Blob files for Nvidia Tegra-powered Asus devices are incredibly useful. This is because they allow us to easily flash images to our devices using Nvflash at an extremely low level.
Given the low level at which APX (Nvflash) mode runs and how this is much more primitive than booting into a standard Android recovery partition, a device with the appropriate blobs is practically unbrickable. Thus, blob files can be used to get us out of seriously sticky situations that would otherwise be unrecoverable without major device surgery.
Naturally, you’d want to have the appropriate blobs for your device just in case anything goes wrong. Thanks to XDA Recognized Developer rayman (and the rest of the crew on the AndroidRoot.mobi team), this is now possible on the (original) Google Nexus 7, as well as the Asus Transformer Prime, TF300T, and TF700.
Flatline creates these blobs for the aforementioned devices. A custom recovery image is used to flash a custom bootloader, as well as to generate the appropriate blobs. This solution is unique from other Nvflash solutions in that doesn’t require a working /data partition for image storage. Rather, blobs can be retrieved from /tmp/AndroidRoot, as explained in the guide linked below.
You can get in on the discussion by visiting the original thread. To go ahead and get started on your own device, visit the developer team’s full guide, complete with modified recovery images and all other required files.

When it comes to source-built releases, there always seems to be that one glaring issue that lingers around long after the others are fixed. For instance, last year the EVO 4G developers had some trouble with getting WiMAX on CyanogenMod 7. Usually it is something minor like the camera or Bluetooth. Two devices that have struggled with this are the ASUS Transformer Prime and the AT&T Galaxy Note.
The original mod for the Transformer Prime was created by XDA Forum Member eSbek and was later tested and confirmed working on the AT&T Note by XDA Forum Member linkkoriri. Given the large number of differences between the ASUS tablet and the Samsung phablet, the method is likely compatible with other devices as well.
It only works CM10 and ROMs based on CM10, so if you’re running a different build, you may be out of luck. To use, download the mod and replace the audio_policy.conf file with the one you downloaded. After that, reboot and you’re done! For the Galaxy Note owners, it has also been confirmed that using the audio_policy.conf from the Galaxy Note 2 dump.
We recently told you about the CyanogenMod team beginning work on CM10. Now, a significant milestone has been reached: CM10 Nightlies have appeared for select devices. For those who aren’t familiar, a nightly build is an automatic build incorporating the latest changes in CM source for a device. Yesterday, CyanogenMod released the list of those devices that would be getting the first round of nightlies:
# The US SGS3 variants (AT&T, T-Mobile, Sprint)
# The Galaxy Nexus variants
# The Nexus S varaints
# The Nexus 7
# The Transformer and Transformer Prime
# The SGS1 variants (Vibrant, Captivate, International, and i9000b)
# The SGS2 i9100g
# P3 and P5 tablets
That list will grow as other devices become ready and receive the blessing from their maintainers to begin nightlies. Be sure to keep your eyes open for when your device joins the list.
Update: We’ve received various reports from XDA Forum Member Scotto70 and others that the Nexus 7 build is currently nonfunctional. So if you’ve got a N7, we recommend that you hold off for the time being!

For those who are unaware, a bottleneck is when a device’s performance is affected by a single weak link. This can be found on electronic devices across the spectrum from tablets to phones to computers, and so on. An example of a bottleneck would be like building a computer with a quad core processor, dual high-end video cards, installing 64-bit Windows 7, then only putting in 128 MB of RAM. The entire system is awesome, but because there’s no RAM, it’ll lag and crash frequently. Bottlenecks can happen in Android as well, as many ASUS Transformer Prime users are well aware. While there may be no helping the guy who puts 128 MB of RAM into a modern computer, ASUS Transformer Prime users may actually have a fix for their bottlenecking woes.
XDA Forum Member TweakerL, after some experimentation and help from a number of others, came to the conclusion that the reason for the bottlenecking may not be only software related. As TweakerL explains:
So, the whole idea here started with me reading an article on how part of the whole I/O problem with the transformer is partially caused by the hardware used as internal storage. I wanted to find out if this had any merit and I figured the best way to do it would be to “replace” the internal storage. I did this by mounting the /data partition to the exteral SD (which according to my research, my specific SD Card is better at writing speeds – allegedly the main problem with the transformer’s internal storage hardware wise). Then I ran a bunch of benchmarks and have been running it that way for about 24 hours and so far it feels great. Anyone is welcome to give it a try, and hopefully with help, suggestions and feedback from the community, we can all take as much advantage of this idea as possible.
In essence, the issues with the Transformer Prime is that when the device is writing data to its internal storage, the very slow write speeds bottleneck the system causing serious lagging problems. The answer is moving the /data partition to an external SD card with better write speeds. Of course, this is only the beginning.
The next steps in development involve also moving the /cache partition to increase performance even more and testing to see what effects this will have on every day activities like Nandroid backups. Additionally, TweakerL gives kernel devs instructions on how to implement the fix on their kernels should they want to. Want more? Okay, TweakerL has also provided a short, easy to follow guide to cloning the data on the internal storage to the external storage so when you flip flop the two, you don’t lose any data. Apparently, the only thing this thread doesn’t do is print money.

Not too long ago we reported to you about the Tegra2-packing ASUS Transformer TF101 being given a solution to bypass the ASUS-locked bootloader. Today, we bring you more good news: You can now use NVFLASH on the Transformer Prime (TF201). The AndroidRoot team (comprised of XDA Recognized Developers rayman, apache14, ieftm, kmdm and lilstevie) are once again responsible for this monumental piece of work.
While Nvidia has provided a Tegra3-compatible NVFLASH binary in their cardhu android images, the specific Tegra3 device needs to be enabled to work with NVFLASH. To deal with this restriction, the AndroidRoot team provides a new version of their Wheelie tool for the Transformer Prime. If you recall, Wheelie acts as a pre-loader for NVFLASH, getting the device ready to interact with NVFLASH and accept commands.
You will need to have an unlocked, unbricked device in order to use this new tool. However, once the procedure is done, you will always be able to recover any software brick—even bootloader—as long as you keep the device-specific files this tool creates safe. The process requires that you follow a number of steps, including flashing a patched bootloader, and that you meet the following prerequisites:
- An unlocked Transformer Prime tablet
- Working fastboot binary & all necessary drivers
- The nvflash binary from NVIDIA (ICS version — this is important!)
- Nerves of steel!
The tool is currently only available for Linux, but there is a Windows version coming very soon. Visit the original thread for more information and to download the tool. Visit their blog to follow progress on other devices.

Much Android development has come in the way of schedulers. Schedulers tell the system how to handle I/O operations. More specifically, they control how devices determine which processes can access your device’s memory, and when. With many schedulers out there from Completely Fair Queuing to Budget Fair Queuing, users can tune their Android devices however they want.
ASUS Transformer Prime users running the stock .28 firmeware now have a new option called Simple I/O Scheduler, which has seen some pretty good results. Applied to the Transformer Prime by XDA Forum Member batoo, the scheduler comes in the form of a module that users can install and enjoy. According to batoo:
I compiled SIO (Simple I/O scheduler) for Prime.
It seems faster than CFQ to me.
It was developed mainly for SSD drives!

Creativity and resourcefulness are two crucial values a good developer must possess. Occasionally in the community a project or an idea pops up that utilizes these values to accomplish something other than fixing code or implementing features. From time to time, a user finds a creative new use for something they already have. One such resourceful Asus Transformer Prime owner, Jason Harrison (XDA Forum Member iksteh), used his tablet as a replacement CCD (Charge-Coupled Device) sensor for his telescope, churning out some really fantastic shots of the moon fueled by the power of Android.
Jason is an Android and Linux fan who dabbles in amateur astronomy. After using several cameras and setups, he decided on using the Transformer Prime’s 8 megapixel camera with the focus mode set to infinite, the exposure set to -1.3, and the white balance set to ‘Cloudy’. Jason, an Android fan since 2.2 (Froyo) and owner of several Android devices, says the camera aperture on the Prime fit perfectly with his 15cm Dobsonian telescope. He is located in Tasmania so the light pollution levels are low.

While not fatal, soft-bricking your Android device can be a disaster. For many devices there’s no clear cut method or tool that will help you out in such a situation. While rooting and unrooting tools usually take much of the press and popularity, tools that help users get rid of soft bricks are every bit as important. The Transformer Prime now is lucky enough to have all of the above.
XDA Senior Member MasterZen88 has released a tool dubbed WSG UnBricker that helps users recover from soft bricks and, as noted by MasterZen88, should only be used as a last ditch effort if none of the other methods to fix soft bricks works. The process, which is a Windows-only .bat file with a number of helper files, is easy to use but users should definitely take care when using it so they don’t flash the wrong files at the wrong times. The tool allows users to select the function they want to use, and then users drag-and-drop the appropriate included file to flash. The flashing takes place via Fastboot, so any Prime that hopes to get fixed with this method must at least have access to that.
Please be careful as to what file you drag and drop when it prompts you
One final note do not give it a file from another device or a non .img file it will flash it anyway no matter what file you drag and drop once you press enter it flashes what ever was dragged onto the script. Also do not drag a radio img when it asks for recovery or in revers, bad things will happen Wile they are fixable by repeating the process I dont want anyone to mess up their device making such a simple mistake.

With the Asus Transformer getting a little home screen love, it was only a matter of time before someone would figure out an awesome way to modify the home screens of its younger brother, the Asus Transformer Prime. Since tablets bridge that gap between mobile devices and computers, their screen size is ideal for not only mobile operating systems like Android, but they can also be skinned effectively with UI’s designed for full sized TVs or computer monitors. An example of this would be the Xbox 360 Dashboard.
The example is not a coincidence, as Transformer Prime users can now make their tablets look and feel like the Xbox 360 Dashboard. XDA Forum Member Charlos_OOO has written up a very nice tutorial with a list of all the software required to make the Transformer Prime look very much like the popular gaming console. To be frank, this process takes some time so don’t start if you have pressing engagements in the near future. The software list required to make this all work is quite long as well. According to Charlos_OOO, you’ll need at least:
DesktopVisualizer ImageCrop (Trial)
FolderOrganizer (light) … to get a text-style app-launcher-Pop-up
A 2D-graphics-tool of your Choice
From here comes one of the longest three step processes on XDA, which each step being broken down into many sub-steps. Don’t be alarmed, however, as Charlos_OOO has written out the instructions beautifully so even those who aren’t as Android savvy can understand them. It just takes a long time.
Additionally, Charlos_OOO has put up a few pieces of opinionated information for discussion, such as the ideal Android launcher that would improve over all the current Android launchers. While not a part of the tutorial, it is an interesting set of fun and awesome features that were suggested.
More information, the full process, screen shots, and more can be found in the original thread.
This week on XDA TV, XDA Forum Moderator and Recognized Developer shenye gives us a basic rundown through some of this week’s biggest development stories. In addition to talking about some April Fools news, Shen highlights the release of the HTC One line and how it should not be compared with the OMAP-based Galaxy Nexus. He then talks about CM9 on the Galaxy W, and how CyanogenMod itself has now found itself a new mascot.
Next, Shen talks about development work and ICS updates for the Transformer, Transformer Prime, Galaxy Nexus, Nexus S 4G, Xperia Play, and the AT&T Galaxy Note. Finally, Shen discusses the release of Instagram and Swiftkey 3 Beta for Android.

It wasn’t long ago that we at XDA brought you news of the Asus Transformer Prime’s Unlocker Tool, and it was only a matter of time before we saw similar user-created tools. As root methods go, there are few easier ways than simply installing an APK. XDA Senior Member sparkym3, with some help from others, has now released his Transformer and Transformer Prime root tool, which offers a number of advantages over the official tool.
The steps are pretty easy to go through and involve really only pressing a single button. Basically, you install the application, run it, click exploit, use the Asus Backup to backup an app, install superuser and then cleanup the temp files. The developer doesn’t specify if the tool is based in any way on the official Asus unlocker tool, but the root method does work on just about all Transformer Prime firmwares. In the words of the developer:
This root app has been confirmed working on current OTAs for the ASUS Transformer (TF101) and Transformer Prime (TF201) Devices.
This includes v22.214.171.124 for the TF201 and v126.96.36.199 for the TF101.
A recent user reported that v188.8.131.52 on TF101 may have fixed this exploit but I have no further confirmation on this.
This method (as it is currently implemented) no longer works with the v184.108.40.206 ROM on TF201.
If you’re looking to easily root your Transformer or Transformer Prime and aren’t running v220.127.116.11, this is the method you’re probably looking for. It has also been confirmed that this tool will be supported for a while, and that future versions will also have new features such as unrooting.
More information, download links, and the full set of instructions can be found in the root tool thread.

XDA Senior Member 1wayjonny has decompiled the Asus Transformer Prime tool using APK Tool, and provided a .zip file for anyone who wants to go rooting through the tool to see what it does, how it does it and, very likely, modify it to work in different ways and possibly for different devices. XDA Forum Member sparkym3 then posted a java version in the second post.
So far, the code that does all the magic has been isolated and revealed and it appears as though the tool registers the Transformer Prime as an unlocked device before actually unlocking the bootloader as was observed in the UnlockFlagandReboot.smali portion of the apk and there have been several other pieces of the code that have been identified as important to the overall process. A few things remain unclear about the process itself. As observed, there’s a registration that occurs before the unlock, which leads some to believe that the unlock tool will blacklist any Transformer Prime and prevent warranty coverage if something bad should happen.
Those eager to check out the code and the apk for themselves can find it in the original thread.

The Asus Eee Pad Transformer Prime is arguably the most versatile and featured packed tablet available today. In addition to packing the exceedingly-fast Nvidia Tegra 3 processor, it lives up to its name thanks to its convertible form factor. And now that we have been graced by the official bootloader unlocking tool, things will only get better.
Thanks to the work of XDA Recognized Developer Diamondback and the rest of the Virtuous ROM team (XDA forum members Flemmard, cjward23, rmk40, chrisch1974, cypis, m-deejay, seo, and eViL D:), we now have the the first custom ROM for the device. The ROM’s initial beta release is limited in scope, essentially offering a full de-bloat, deodex, zipalign, and a few performance tweaks. However, it can be seen as the harbinger of many good things to come in the Transformer Prime development world.
In the words of the developers:
- Virtuous S Series
- Based on the lastest ASUS release (WW 18.104.22.168)
- Fully zipaligned
- Stock kernel
- Optimized for fluid performance and usability.
- Included 1.6Ghz OC (more on that below)
First custom ROM for the Transformer Prime. Need I say more? Head over to the ROM thread to get started on your device today!
