I've just format system and unfortunately the rom isn't installing and now it show nothing when booting up but blank screen. I still have access to boot loader and recovery mode (no backup). Is there anyway to unbrick it?

will this unbrick method delete all the user data ?

btw, if do a factory restore, all data will be delete ? or only data under certain folder will be delete ? anything/folder will left after factory reset ?

Computer crashes
Hey guys, I was having some issues with the computer crashing with usbxhci errors, which sounded like driver errors so I tried uninstalling and reinstalling the usb drivers, (using asus gaming laptop with usb 3.0, windows 8 64 bit), was still blue screening when I entered download mode, what ended up working was using the download mode technique using the usb slot on my nintendo wii, unplugging it and plugging into my computer as it was in download mode. The problem I am having now, is its not wiping, adb wipe just enters recovery, so i'm wondering if theres a way i can wipe using total commander? I tried renaming the /data folder but its read-only, so i'm not sure what else to try.


edit: I wasn't able to get into factory reset using volume down and power, but for some reason now it worked. looks good now, thanks.

edit #2 a million years later

Also found some seemingly more stable intel drivers for any Windows 8 users out there having this problem. Check out

Original LG firmware
As you have the Korean version and you have to file the serial number and type I assume you will get the Korean software again?

Does anyone know how to retrieve an older KDZ file for Bell E973? The URL generates a link for H firmware, I need F to downgrade to root. Thanks in advance for the help!

So, if you get stuck on a boot loop like I did, you can press Vol Down and Power to wipe the data on the phone, as the wipe.bat in the first part is broken.

cab file to kdz file
Ok I have the file downloaded to do the fix, but the file is a cab file but the software wants a kdz file. How do I change the file format?

I have a Sprint LG LS970, but it says made in Korea, so does that mean I have the Korean version?

Also when I try the steps on the first page, I get a cab file. I tried using the app and the link ( way. You can also see in the file it shows it as a .cab file.
and my MEID number on back of phone is only 14 digits.

Any ideas? Thanks for all you do!
