Kexec Bootloader Bypass Released for Motorola Droid Razr

Kexec

Users of many Motorola Android devices have been clamoring for an unlocked bootloader for quite some time. There have been petitions signed, social media accounts spammed, and users have really shown that bypassing that unlocked bootloader means a lot to them. While Motorola hasn’t been much help in unlocking bootloaders, there has been some development going on to fix the problem once and for all. While many Motorola phones are still without an unlocked bootloader, users who own the Motorola Droid RAZR now have the option to simply bypass it completely.

MultiROM Available for the Samsung Galaxy Note II

20121118T055436

With so many ROMs available on XDA, it’s incredibly difficult to find the one that suits us most. We must choose between modified stock firmwares, AOSP-derived ROMs, or alternate OSes like Ubuntu Touch and Firefox OS. There are solutions to make the choice a bit easier, and one of them is multiboot. XDA Recognized Developer Tassadar‘s MultiROM is the ideal perfect solution for all you folks that can’t decide which ROM should be used as a daily driver.

In the last few weeks we have been seeing MultiROM popping up on various devices, but it’s certainly nice to see its debut on the popular Samsung Galaxy Note II, a device that was released nearly two years ago. Kernel and device tree imp. . . READ ON »

Learn How to Boot Multiple ROMs on Your Sony Xperia TX

Xperia TX_white_group_SCR1

If you’ve ever tried to get multiboot functionality to work on your Android device, you’ve probably heard of kexec. This is a method of live booting different kernels without having to flash them or using fastboot. Kexec has been used as the basis for bringing multiboot functionality to various devices such as the HTC Droid DNA and Sony Xperia M. And in fact, as of right now, it’s pretty much the only viable way of getting such feature working on your Android device.

With this said, we see another device taking the kexec route in order to boot multiple ROMs, this time being the Sony Xperia TX. This is made possible by XDA Senior Member updating, who has written a tutorial going through the necessary steps i. . . READ ON »

Learn How to Run a ROM Off Your External SD Card

Run ROM off your internal SD

Aftermarket modding has been around since practically the beginning of the modern day smartphone, but its build-up on Android has been pretty explosive. Since the early days of the HTC Dream right up to the current generation of devices, almost every device has received its fair share of third party modifications. These can come in the form of ROMs, kernels, scripts and more, but ROM development has taken front and center stage. Obviously, the word ROM stands for Read Only Memory. And for our modern devices, that’s the NAND-based Flash ROM that makes up their internal storage. However, in the development community, the term has come to mean a custom operating system image that you insta. . . READ ON »

Xperia Boot Menu Ported to the Xperia P in Preview Form

CPyC0nW

Back in September, we talked a little bit about XDA Recognized Developer munjeni‘s Xperia Boot Menu. The project, which was originally compatible with the Xperia U, Sola, and GO allowed users of those devices to enjoy the benefits of multiple ROMs without having to lose any data while switching between installations.

While the previously featured Xperia Boot Menu was great for Sola, U, and GO users, this naturally caused Xperia P owners to feel a bit left out. Thankfully, XDA Senior Member percy_g2 has made progress in porting munjeni’s Xperia Boot Menu over to the final member of the device family, the Xperia P.

Just like munjeni’s original work, this solution relies on kexec to . . . READ ON »

Boot Multiple Roms on the HTC Droid DNA with Unofficial MultiROM Port

droiddna

It seems like XDA Recognized Developer Tassadar‘s MultiROM seems to be quite the popular method for different devices to boot multiple ROMs nowadays, considering that MultiROM was originally developed for only the Nexus 7 and has since been ported over to a number of other phones such as the Sony Xperia M and the Optimus One. And the community doesn’t look like stopping any time soon, as the HTC Droid DNA, a.k.a. HTC Butterfly, has recently received an unofficial MultiROM port.

This comes thanks to the efforts of XDA Senior Member jamiethemorris, making it possible for users of the Droid DNA to run multiple ROMs (not at the same time of course) without the hassle other devices must go through. The in. . . READ ON »

Boot Multiple Roms on Your Sony Xperia M with MultiROM Xperia

MRX

MultiROM is probably a name that many on XDA will recognize, especially if you’re an owner of one of the officially supported devices, such as the Nexus 7, for which MultiROM was originally developed by XDA Recognized Developer Tasssadar. As you may have guessed from the name, MultiROM is a tool that enables one to boot multiple different ROMs on a supported device, without going through all the hoops such as wiping a ROM or performing backups.

Well, it seems like another device has discovered the magic of MultiROM, with the Sony Xperia M receiving an unofficial port of the tool called MultiROM Xperia, courtesy of XDA Senior Member alvinhochun. As of right now, MultiROM Xperia is in its alpha phase and is . . . READ ON »

Enable Multi-Boot on the Xperia U, SOLA, GO

CPyC0nW

We’ve featured multi-boot methods for various devices in the past. If for no other reason, having multi-boot is just plain cool because it allows you to try various ROMs without having to lose your current installation.

Now thanks to XDA Recognized Developer munjeni‘s app Multi Boot Manager, you can accomplish this relatively easily on the Xperia U, SOLA, and Go. And thanks to Senior Member NoobCoder, there is now an easy guide for using munjeni’s creation. The guide, which is available in our newly created Sony Cross-Device Development Forum, shows you how to get multi-boot up and running on your own device.

Kernel Lighter Loads Kernels on Tegra 3 One X Away from PC

slide-1-white

Up until recently, loading kernels onto the Tegra 3-powered HTC One X has been a relatively difficult affair. This was due to the fact that unlike its Qualcomm Snapdragon-powered cousin (originally called the HTC One XL), the Tegra 3 variant has not received S-Off. While not everyone would be bothered by needing to be stationed at a traditional computer in order to proceed with kernel flashing via fastboot, it can’t hurt to have these restrictions lifted.

In order to get around the issue, XDA Recognized Developer Thunder07 first looked to kexec. The name should sound familiar, as it has been used countless times to bypass various security measures or add additional functionality to unlock. . . READ ON »

Get More, Much More From Your Nexus 7 with MultiBoot

n7multi

The Nexus 7 is one of the best devices for a few reasons: perfect size, loaded with power, easy to use, and most importantly best bang for your buck. Yes, it has a few quirks, which many of us are annoyed at like the lack of an SD card port (devs are working on this as we speak), but overall this is a great device for people getting started on Android, as well as for those who are more seasoned in the field of Android development. So, how could you make something this good even better? XDA Recognized Developer Tasssadar can answer this question with his latest creation: Multi-Boot for the Nexus 7.

Official CM9 Getting Closer for Epic 4G Touch

cm9

With the title of “Worlds Longest Name for a Smartphone” already in the bag, the Sprint Samsung Galaxy S II Epic 4G Touch (SSGS2E4GT) has become known as the SGS2’s Red-Headed Stepchild. Back when Samsung released the US variants of the SGS2 i9100, the E4GT was the first to appear. However, it has taken the longest to receive official ICS from Samsung. Coupled with taking longer to receive official CM9 love, and you have a device that seems to have been forgotten.

XDA Recognized Developer darchstar has done a great job, with the help of the rest of Team Epic CM, in continuing to work on CM9 for the E4GT without much help, naturally, from Sprint and Samsung. After months of leaks, Sprint sta. . . READ ON »

Bypass the Locked Bootloader on the Verizon Galaxy S III

Verizon Galaxy S III

It can be said that development on the Verizon Samsung Galaxy S III has been a struggle. What was once anticipated to be a utopia of development between the four major carriers due to having nearly identical Galaxy S III devices has been marred by the locked bootloader on the Verizon version. Understandably, this has somewhat stifled development for the device, as the other three US variants rush forward at a breakneck pace while Verizon developers are held at the starting line.

This is a problem that CMTeamEpic is looking to fix. By reviving a concept Motorola Droid RAZR members will recognize, CMTeamEpic plans to get beyond the locked bootloader using Kexec, the bootloader workaround. The premise is t. . . READ ON »

Atrix Bootloader Almost Bypassed — Like a Boss

atrix_lockdown

Cracking the Atrix bootloader is something man has been on a quest to do ever since it was released. When I say man, I’m of course referring to the fantastically techy ladies and gentlemen in our forums.

XDA member kholk has been working very hard to make this a reality, rather than a dream. He’s successfully managed to run Kexec, but he needs a kernel and the exact address of the boot parameters.

The kexec has been provided for any developers who wish to help, and this is exactly what kholk is looking for. Some dashing, strapping, and helpful developers, who are willing to lend a hand to a great member of the community.
