A while back, several XDA members were concerned with MTP. For those who don’t know, MTP stands for Media Transfer Protocol and it replaced USB Mass Storage on a good number of Android devices as the de facto way of connecting to a computer. There were quite a few problems with this—none bigger than some operating systems not working well with MTP. Our TV crew has discussed solutions before, but not every device had a solution for MTP. Now, LG Optimus 4X HD users have a solution.
XDA Forum Member bullghost has released an application that gets USB Mass Storage working on the Optimus 4X HD. The tool started out simple at first, but over the last few weeks it has gotten a number of stability and usability updates. Currently, it is on version 3.0.
Using the application is pretty simple. Users will install the app just like any other APK. From there, simply open the app and follow the instructions. Once all the settings are in place, users will be able to connect to their computers and use USB Mass Storage instead of MTP. This will definitely be helpful to those Optimus 4X HD owners who use an operating system that doesn’t support MTP.

Obtaining root is definitely among the top priorities of developers when a phone is released. Root and custom recovery is about as far as most users go, as once they get the ability to flash ROMs and other mods, they don’t need much more. However, many who wish to dig deeper require an unlocked bootloader. The LG Optimus 4X HD has already attained root. Now devs are looking to unlock the bootloader using a recently released bootloader dump.
XDA Senior Member wkpark has uploaded a bootloader dump from a Korean post in another Android hacker forum. It was ripped from the stock KDZ file, and is ready for devs to play with. In addition to the bootloader dump, wkpark has added a couple of other useful items, including:
●dzextract script added
●flash.bct.encrypt file added
Discussion has already begun on the possible ways to unlock the bootloader. Several members have already dug in and started looking around for possible unlock methods or exploits. There isn’t anything successful yet, but brainstorming is always important. That’s always the process, though. It’s unclear whether the LG Optimus 4X HD will ever get the bootloader unlocked. However, if you’d like to contribute, be sure to visit the original thread.

A short time ago, we brought you news about root and recovery for the LG Optimus 4X HD. Thanks to this, ROMs could be created and development could begin on LG’s newest Android offering. This is definitely good news for early adopters of the device. Now, there is an application that can help control things like processor clock speed on the Optimus 4X HD, and unbelievably, it actually doesn’t require root thanks to an undocumented LG API that works on stock firmware 10C.
We have brought you news on multi-core mods that bring more control over the CPU before, but this is definitely unique. XDA Forum Member atipon has released an application called LG GearBox, which can change things like the device clock speed and the number of active cores without requiring root access. As atipon explains:
- Help extend your battery life.
- Manually control CPU speed and active cores
- Integrated with Power saver option in system settings.
Whenever your turn on Power saver, cpu and active cores will automatically adjusted.
It uses undocumented LG API, tested on stock firmware version 10C.
No root required
The application has had a few testers and has been reported working for users with and without root. It hasn’t had a lot of testing as of yet, though, so the old adage of your mileage may vary applies. As stated, though, more testing is required.

As usual, the first thing device owners strive for when a new device is released is root access. Without it, more than 90% of the things we do around here wouldn’t work. So when a device gets root, it’s much like a welcome party courtesy of our developers. The LG Optimus 4X HD, which was released a little more than a month ago, has received not only root, but recovery as well.
For root, XDA Senior Member alexp999 posted the tutorial. XDA Senior Member Dexter_nib posted the tutorial for custom recovery. Combine both, and you have the freedom to do pretty much whatever you choose to do.
The root process is a little tedious, but pretty easy. Users must first enable USB Debugging and Install From Unknown Sources, and then install IS11LG_SystemBackupTest.signed.apk to their device. After that, reboot, connect the phone to your computer—this is a Windows only tutorial currently—and run the root script. Once finished, users install SuperSU, remove IS11LG_SystemBackupTest.signed.apk, and rejoice in the rooted goodness. Installing recovery is even simpler, with users installing a single APK to their devices.
