Help me Unbrick LG K371 [Answered]


Hello

I accidentally downgraded a K371 from V1.1N toV1.0b
I think it is downgrade from Nougat.

Phone is Dead, and it only connect in 9008 mode

I cant find this software anywhere (the latest nougat) also I cant find any way to recover the brick and get the phone to boot to download mode.

There is a new Octoplus JTAG Box update which says it can boot any eMMC if you have the proper Loader, howeber I dont know where to get such loader for K371.

I have a Firmware Backup from the phone I read before the downgrade, but because I cant go to download mode, I cant flash it.

the backup I have is:

MSM8909__LG-K371__K37111n__V11n__AOSv6.0__LGK371AT-00-V11n-ATT-US-SEP-29-2016-ARB01+0

and it has all of these files:

boot.img
emmc_appsboot.mbn
Extra_files
fact.img
gpt_backup.bin
gpt_main.bin
INF_FlashSet.xml
laf.img
misc.img
NON-HLOS.bin
persist.img
rawdata.img
recovery.img
rpm.mbn
sbl1.mbn
sec.dat
system.img
tz.mbn
_Android_Info.txt

any Idea?

Hello.

Currently we have no eMMC pinout for this device, but You can try to connect it via USB and, if connection will be successful, do "Factory Repair".

To connect the phone via USB, try to do the following:

1. Install the latest Octoplus JTAG Pro Software version (https://octoplusbox.com/en/download/software/).
2. Select "USB" interface option.
3. Select "Brand: Custom Settings".
4. Select "Device (Core): Qualcomm MSM8909".
5. Select "Loader: QLoader_v1".
6. Connect the phone to PC in "Qualcomm...9008" Mode and press "Connect" button in Software.
7. If the phone will be connected correctly, do "Factory Repair" ("Factory repair" tab in Software) using the latest original LG firmware for this phone.
8. Disconnect the phone and try to put it into Download (Emergency) Mode and re-flash it using LG tool.
9. Post here the result.


There are a few USB loaders for Qualcomm MSM8909 CPU in Software. Try also to connect the phone using each of then. You should re-connect the phone before trying to use new loader.
