Root [AT&T] Did I just brick my new LG G2 ?

Spakxxx · Feb 7, 2015

can you show me some custom roms? just to be sure and see what's like

iowabowtech · Feb 7, 2015

Sorry man I haven't done custom roms on this phone for well over a year so I don't even know what's out there anymore. You'd want to peruse xda developers for that.

Cheers mate.

You certainly can though it's concerning that the D800 tot did not apply and reverted you back to fastboot mode. It did say D800 inside the phone as the model right? If so, this has happened one other time. In that case what we did was flashed the d800 bootstack. This should return download mode again. Then use download mode to this time flash the REGULAR unedited tot and dll via LG Flash Tools.

So...
download and fastboot flash aboot, boot, laf, dbi, tz, sbl1, rpm from HERE.

Remove any numbers/dashes in the file name by renaming them so you end up with 7 files called..
aboot.img
boot.img
laf.img
dbi.img
tz.img
sbl1.img
rpm.img

Then fastboot flash those..

fastboot flash aboot aboot.img
fastboot flash boot boot.img
fastboot flash laf laf.img
fastboot flash dbi dbi.img
fastboot flash tz tz.img
fastboot flash sbl1 sbl1.img
fastboot flash rpm rpm.img

Once done, disconnect phone from PC. Long press power for 15 seconds to power off. Then press and hold volume up while connecting to PC to enter download mode which should be restored now.

Next use LG Flash Tools to flash the regular 10o tot using the regular lgflash.dll both found here:

http://downloads.codefi.re/autoprime/LG/LG_G2/D800/Stock_Firmware

The last 2 files in the list are the tot and dll. Unzip the 10o file to reveal the tot inside. If that doesn't work to restore the phone, I'm not sure what's up.

Where can i get these files for the T-Mobile version?

Thank you, I'm going to attempt this with my G2 I've managed to break.

I'm assuming i need the 20A files because my software version is 20e?

Yeah either would work but I typically go with the newest available so the 20a is what I'd do.

This is a T-Mobile G2. It boots fine but I accepted an OTA and now I can't get to download mode. OK, I've booted into Ubuntu. When I plug in the G2 it doesn't show me the multiple partitions, it just shows me the correct internal memory of the phone. When I type ls /dev/sd* it doesn't find the phone. And I thought this was going to be easy.

If you're booting fine, it's not going to be detected like that in Linux. That is for phones that are in bulk mode which yours is not. So depending on which OTA you accepted, if it's Lollipop (without working download mode), hopefully you somehow managed to get root. Because if not, you're stuck as is right now unless somehow you managed to retain TWRP recovery in the process, assuming you even had it to begin with.

I have root. I'm on D80120e. I never had a custom recovery. Just root.

You can dd write the bootstack from a booted state then with usb debugging enabled and in adb shell after having placed the img files onto your sdcard ahead of time.

adb shell
su (if not already # prompt, otherwise skip that)

dd if=/sdcard/aboot.img of=/dev/block/platform/msm_sdcc.1/by-name/aboot
dd if=/sdcard/boot.img of=/dev/block/platform/msm_sdcc.1/by-name/boot
dd if=/sdcard/dbi.img of=/dev/block/platform/msm_sdcc.1/by-name/dbi
dd if=/sdcard/laf.img of=/dev/block/platform/msm_sdcc.1/by-name/laf
dd if=/sdcard/rpm.img of=/dev/block/platform/msm_sdcc.1/by-name/rpm
dd if=/sdcard/sbl1.img of=/dev/block/platform/msm_sdcc.1/by-name/sbl1
dd if=/sdcard/tz.img of=/dev/block/platform/msm_sdcc.1/by-name/tz

If you have a working stock recovery right now, you'd be safest to either zero it or install a twrp recovery.img. In case anything goes wrong with restoring download mode using the above commands, you don't want a working stock recovery or it'll leave you in a state where you may not have any means to recover as the stock recovery is worthless but will also prevent fastboot mode from presenting itself as a bailout.

Once done with the command set, disconnect phone and close out of cmd/terminal. Long press power for NO LESS than 15 seconds. Do not let up when you feel the first vibe at around the 10-12 second mark, you must keep holding for another solid 5 seconds after that to power down the phone entirely. Then you should be able to enter download mode at that time and flash stock firmware. Which I'd personally recommend in order to get all your partitions updated to the same firmware version as you're going to be flashing older ones along side your otherwise newer 20e in your current state.

Then you can decide how far you want to OTA your way forward, root, etc.

I have no recovery. I get the secure booting error when I try to factory reset. Trying to go into download mode does nothing!

Then you're all set to do the above as written. Should give you download mode back and you can recoup from there.

If this works I'm going to find you and kiss you. After I grow a couple days of stubble.

This LG FLash Tool. In the select type which one is GSM?

The one that does kdz's? If so, just leave it cdma, it doesn't matter in that tool. Choose the CSE option when flashing. It's the one that will totally wipe and clean install and from your current position, that'd be highly desired.

Demontooth · Apr 2, 2015

Here goes nothing.

You are the man. THE MAN.

I'll take a raincheck on that kiss but if you spot any wayward Victoria's Secret models with a similar mentality, send them my way will ya?

Will this method (the ubuntu stuff) work for an AT&T LG G2 that, for reasons unknown to me, bricked itself out of nowhere and is now only detected as qhsusb_bulk? I've never rooted or tampered with it so I don't have root. I just want to make sure this won't further hinder my chances of getting this thing back to working order.

You should be able to restore download mode from a linux environment yes. Provided that you are dealing with qhsusb_bulk (9006). A good clue that you are dealing with a 9006 brick is when plugging into a windows machine, it'll try to mount a bunch of "drives" which are actually the phone's partitions.

tenagainstsix · Apr 17, 2015

Yes, it did exactly that. So, I guess I'll give this a go this weekend when I have lots of time to devote to it. If you don't mind the question, do you have any idea why a plain, unrooted, completely stock phone would do something like this? Is it a sign that it's dying/dead in some way?
