G3 Fastboot Issue/Cannot format laf partition

[Meshuggah27]

Hello All,

I am currently trying to flash TWRP onto my phone, and booting into the Operating system is not possible at this point. I can get the phone into download mode and stock recovery (The phone has never been rooted or flashed, it is bone stock). I cannot figure out for the life of me how to get TWRP flashed onto the phone with either download mode OR ADB commands via the stock recovery. I cannot figure out how to successfully format the LAF partition to access fastboot. Can anyone provide some assistance? I will paypal you money if necessary. I need this phone up and running ASAP. Please help!

You MUST have a "Bumped" TWRP.

The BEST way to do it is to flashtool zv4. Root and unlock it.
As for rooting zva-e, there are procedures linked in the thread. Unlocking the boot loader are there too, I believe. Doing it this way may cause issues. So I all depends how much work you want to go through.
Personally, just use ZV4, root/unlock. Then flash modem and whatever ROM you want.

Hey engine,

I did use flashtool to restore to ZV4, but it will not boot into the OS and just keeps powering itself off at either of the LG bootup screens

And that's just stock? Straight from flashtool? That shouldn't happen unless you wiped something out trying to do the laf partition.
Are you sure you have the Sprint 990?.

There's other threads here, one is stickied in "General", that you might need to read then. They're about fixing other issues that might feel you.

I appriciate your help! Yes, the phone restores just fine using flashtool with the ZV4 .tot file, but once it reboots it wont make it past the LG logo bootup screen. One time it made it all the way into the OS, and went through the activation process, then powered itself off. Now it wont reboot past the second animated LG logo.

I should also mention that sometimes when restoring the .tot with Flash Tool, it powers itself off in the middle of it and just keeps booting into download mode. It always happens anywhere between 30-60% when it says SYSTEM in the progress log. Could it be that my phones internal memory that stores that information is bad?
