Well, I need to help a friend also. He took ota and now there is no Download mode or recovery.

If I press power or try to enter in recovery, I get only a red pulse led.

I connected with Ubuntu, but I don't see it under disk drive partition. Is there any help guys? Thanks in advance
[G2 General] snnail:
how can I flash the laf image from the kdz to the laf partition?
[G2 General] spikyshotgun:
I hope somebody can help me out here. I have a Att G2 on stock 4.4.3 kitkat D80020y. I was rooted with stumproot but still on stock recovery. Then I heard the lollipop OTA coming out and in trying to prepare for it I "unrooted" the phone by selecting permanent unroot in Supersu app. Following that when I checked for OTA and it wasn't showing up, I realised it won't show up as I was using T mobile on Att phone.

So, I thought that's easy, let me just root again with stump root and manually install it. But the problem is Stumproot is now unable to root my phone! Towelroot doesn't work either.

Now, if I try getting the OTA by borrowing an Att sim from a friend, will I get the issue in this thread? If yes, then how do I get lollipop OTA?

Thanks a lot.

[G2 General] bitdomo:
You will use the dd command.

dd if=/sdcard/laf.img of=/dev/block/platform/msm_sdcc.1/by-name/laf

You have to do this in superuser mode. For that you have do to the su command before flashing the laf image
[G2 General] bender_007:
I will. Currently on work
[G2 General] snnail:
This is too complicated to me, I flashed 27a bootstack and right now I can get into fastboot mode.
[G2 General] bitdomo:
Then just use this command

fastboot flash laf path_to_laf.img
[G2 General] snnail:
How do I get the laf.img?

After I Extract my kdz file I got a laf_622592.bin file.
[G2 General] bitdomo:
That is it

fastboot flash laf <<path_to_laf_622592.bin>>
[G2 General] snnail:
Is this the exact command?

Sorry, i'm not familiar with command mode.

I did the flash, and it became my question at first.

Everything works fine and I also got TWRP recovery, I believe it is 2.8.x.x and it runs good also.

My problem is I want to unrooted it and flash it back to factory stocked version, I cannot get into Download mode.

It shows some "error: Boot certification verify"

Quote:

ERROR : boot certification verify

[1040] ------------------------------------------

[1090]

and the screen goes black but still power on.
[G2 General] bitdomo:
try this

dd if=/dev/zero of=/dev/platform/msm_sdcc.1/by-name/laf

This will nuke the laf partition

and then flash the laf partition

dd if=/sdcard/<<wherever the laf.img is>> of=/dev/platform/msm_sdcc.1/by-name/laf
[G2 General] snnail:
Thanks for your reply, problem fixed.

This man@da_reeseboy gave me a solution.

"It sounds like whatever method you used to get recovery didn't replace the laf partition (download mode) when it replaced your aboot and boot partitions.

Assuming you are on 39a, you should be able to flash the 39a bootstack from xdabbeb's resources thread and that will get you a working download mode again."

[G2 General] paterantonis:
Hello, my LG G2 d802 was showing as unformatted disk drives, so I started doing what this guide says. Everything went right up until to the point I had to flash the recovery file. Before that everyone one of them (1- sbl1.img 2- aboot.img 3- rpm.img 4- tz.img) worked fine ( I was getting the data that got in and out). For some reason, when I was trying to flash the recovery file it would say that there is no such file or directory. Then, I tried to rename the file, check the location but everything was correct. Then I pressed the power button to see what the phone would do (probably silly move) and now it has stucked showing the logo. The computer won't recognise it at all (not even as unformatted disk drives) and the phone is on boot loop. Any ideas?

Do you get multiple partitions mounting on Windows when you connect your phone?

When you disconnect your phone, do you still have /dev/sdc? It's possible /dev/sdc is something else, like your live usb.

If /dev/sdc is being mounted when you plug your phone in and unmounted when you disconnect your phone.. try the following commands,

su
partprobe -s /dev/sdc
ls /dev/sd*

Wait my mistake, is there any way that does not involve installing/booting an operating system?
[G2 General] d00lz:
Without an Operating System all you have is your BIOS and maybe some form of redundant Bootloader. Both are very basic when it comes to functionality. You absolutely need an Operating System for this method. Just download a Linux distro that includes the GPT fdisk utilities and dd binaries (almost every single one includes both of these) and make a Bootable USB with Rufus.

RED LED blinking when i try to get into Download or Recovery mode

[MENTION=6518747]hacklockx[/MENTION] and [MENTION=4554553]aftabalam8c2[/MENTION]

I was trying to flash stock rom using LGFlashTool and suddenly i got error and everything went haywire. Then I tried to get into download mode, the LG logo popped and then RED LED was blinking.

I followed this method. Extracted .bin files from .kdz(except misc which wasnt there), after that renamed the .bin files to .img. I copied (using dd command in Ubuntu) the .img files to their respective partitioin(such as sdc1 for modem, sdc2 for sbl1 and so on) after that i tried to boot my phone in dowload mode (removed the USB cable, pressed Vol down and power key and plugged my phone in PC) I am still getting RED LED blinking. Same thing happens when I try to get into Recovery mode (THE RED LED BLINKSS :/)

[G2 General] kuwlij:
It all started from flashing a rom intended for another G2 version :( every recovery attempt seems to be throwing me further and further back.

I got to the point that this post was meant to; phone showing up as qhsusb_bulk in Device Manager, a bunch of drives are mounted, etc..

I followed instructions .. Partager.info specified in the OP in big red text to get the right firmware version - not knowing precisely, deduced that since I have an LG G2 d802 , 16GB (from Europe), I would use files from 10b_EUR_16G directory. I followed the instructions correctly, when rebooting, it did not fix the issue. If anything it's made it worse now.

The device is still being recognised as qhsusb_bulk but the drives are no longer being mounted; not in the windows pc or linux one.

Any help on this please?

Did this happen because I chose the wrong d802 firmware version? How do I confirm which firmware version is the right version? I don't really care what firmware version i'd get installed, I just want to get to the recovery screen. At this point, I'd be stoked if I can just get it back to stock.

I had backed up everything (clockwork & titanium) before jumping into this rabbit hole of hell :(

[G2 General] N3M3SYS:
Hello, to all, I'd like to share my experience and problem with my LG G Flex, as a last hope to find a solution to unbrick it.

I know that the talk here is about G2's, but I saw many users reviving their Flexes with OP's method.

So here is what I did in steps:

1)I rooted my Lg g flex F340L

2)New OTA, downloaded, but failed to install after reboot. The message was no OTAs for rooted devises

3)Tried to unroot, but with no success. Still no installation of OTA.

4)Found, and flashed the stock F340L rom , (had an EFS backup), from another user here(.tot file), with LGFlashTool.

5)SIM card was not recognized any more (Greece, Vodafone), so no calls. Did all the updates, but no SIM, still.

6)Hard reset, still no SIM.

7)Decided to flash stock F340K kdz rom, and install CWR. All good, SIM detected, OTA downloaded, but after reboot stuck at CWR nenu. Whatever I do just CWR.

8)No download mode, or usb support, just an LG FLEX unknown device. Got some drivers only to be seen as lenovo ADB device.

9)I found the test point on the motherboard and short circuit it. Got a qhsusb_bulk(qualcomm 9008) under COM ports, but not on a specific port.

10) No flash capability, and no partitions to try and flash the 10 or so, images. Ubundu, no luck with the partition detection either.

11)After many reboots and button long presses the CRW came back...again :(

Well as I can see, there is not so much support for the korean variants and I might have destroyed my phone. So, I need your advise in changing the motherboard. I found M/B's from AT&T and Sprint variants, to install to my F340L. I think it will work. After I will purchase an unlock code from lets say ebay to unlock it to all GSM networks ( I live in Greece).

Comments, suggestions, guides welcome. Thanks

[G2 General] thebufenator:
Hey I really need some advice.

I bricked by phone using the one click root tool.

VS980, had lollipop on it.

I had fastboot, and used the tool on my computer to reflash the aboot, laf, recovery, etc. Now nothing works.

I followed this guide to relfash those files using the dd command in Linux. Including twrp recovery for the recovery partition.

Now the partitions never show up. Phone still doesn't boot. If I plug it in on windows, I get the QHSUSB_BULK, but no drives or partitions appear.

I am at a loss at this point, what can I do now that it only shows QHSUSB_BULK but no drives?
