[GUIDE] Unbrick a Hard Bricked L90 all variants

[tramuyo]

I have tried everything mentioned here but it's not working for me. When I connect an USB cable to my LG L90 this is what I see under ports (see device_manager.png attached)

When I use the boardiag application to run the test I keep getting the message "No response from the device. Check PMIC first and if still boot problem, replace AP." See error message screenshot.

I love this phone and want to get back working. Please help me.:crying:

seems boarddiag is outdated or phone AP (application processor) is totally messed up. Im at the same boat, hope to get some sort of solution... soon

hello

how to flash these files and when i enter the button it shows partition does not exist please extract the files from the total binary image.. WHY

Hi... this post is creating an optimism in me for a lovely LG D410, L90.. that broke into a boot loop, and only option was to remove the battery to keep it at peace.
When I found this post, I was delighted, and I then followed the entire process of shorting the test point to ground, and got the HS-USB QD Loader 9008 on the Device manager consistently. I then followed the further instructions to download aboot, BackupGPT, but when I tried the restore boot img with 'boot', I got this error "boot partition write fail.. sector 0x50000 test aborted". I tried several times ending at the same. Can any one guide me from here?

Hi guys.. now I am not sure what worked.. I tried one more time after logging the above post, and voila.. the flashing of image files are completed one after the other without any error.. ! However, after I reconnected the battery and to USB, I get flashing battery charge icon at 0%!!.. The same repeats even if I plug to main charger.. I made a progress.. but still way to go.. any clues how to come out of the battery icon flash issue and what it means??? The phone does not start when I press power button... after a while, I see LG logo also is flashing alternately with 0% charge indicator.. dont know if its a battery issue.. getting optimistic further.. but not sure what the fix is..

 

[opeller]

Thank you!
You made it possible to save my device. Was sure it was a gonner and that I made 1 mistake too many to be able to fix it myself. Thank you so much!

Umm..... How did you get the IO shield off?

---------- Post added at 06:25 PM ---------- Previous post was at 06:21 PM ----------

So I hardbricked my D415. I don't know how exactly but there was a guide on XDA where it mentioned flashing aboot and using Flashify to flash TWRP. Now, Windows sees my phone as multiple drives (probably every single partition) and no qhsusb or Qualcomm 9008. Should I try this method?

The d415 doesn't need its aboot flashed to unlock bootloader you just need fastboot to do this and the IO shield just pops off.

Can anyone help me? On PC only appear Unknown USB Device (Device Descriptor Request Failed).

 

[DavidXanatos]

My phone is being detected as "QHSUSB__BULK" not "QHSUSB_BULK" when i force it to install the driver, the b2b application complains when I press start.
the log says Failed during lading flash programmer
Test Aborted!!!

I did not have to short the pin to get to this state, just hold down he power button and plug in the cable.

is that wrong? do i need to short the pin in any case?

Also I see a device called "Qualcomm MMC Storage USB Device" which appears to be the internal MMC exposed as a normal writable usb drive can I use this somehow to flash the flash? DD some image files to it may be?

Updating the drivers as said in the first post does not work as the device name is slightly wrong, reinstalling them manually also does not help.

About the unbrick process: All passed well, with success.
But now, after the unbrick process, my L90 D410hn shows only "Battery 0%".
How do I solve this?

i know im a bit late but i still have a question, i somehow ****ed up my download mode (it now thinks its fastboot) and i cant factory reset. when i try to reset itll get stuck at factory reset processing.
i tried these steps again but it still doesnt seem keen on working. any advice?

 

[hessien zaghloul]

when i put the battery it showed me

450 Fastboot mode started
500 udc_started()

automatically and starts rebooting, and when i plugged the usb cable

450 Fastboot mode started
500 udc_started()
660 -reset-
670 -portchange-

and there's no way to turn it off
and still rebooting after 10 seconds and i can't enter the download mode.. is there any thing to stop the phone from rebooting?
