Dear all,
and thanks in advance to anyone willing to spend some time to help me.
It all started few days ago when I turned off my LG L9 (updated to the last version available for my brand (Italy - TIM), I believe it was Jelly Bean V20C).
When I turned on the phone again, it was stuck on the lg logo.
Then I started to read this forum, and the first thing I tried was the HARD RESET. After that, a sadly image of the android robot with a red triangle lying upon its body appeared.
This image now shows up every time I boot my phone, just after the LG logo.
Then I tried:
- recovery from LG Mobile Support Tool
- followed this guide: [GUIDE] [UNBRICK][ROOT] FLASH Any LG Factory ROM (kdz) WITH OFFLINE FIX
- tried KDZ update tool alone (3GQCT in combination with all modes: DIAG, EMERGENCY, CS_EMERGENCY).
In order to use the Offline fix guide, I run fastboot with option number 2, to upload ICS x-loader and u-boot, otherwise the phone was not recognized by the tool (_IsConnectedPhone(0)).
But in all cases of kdz update, the phone reboots at exactly 90% of the process and after the initial LG logo the red triangle is back again .
Harder reset won't work either after the update.
I tried Italian firmware V10A_00, V10B_00, V10C_00, V20C_00, but none of them works.
I noticed that after the update to an ICS firmware, when I try the hard reset procedure, I can see the android recovery image just one frame before the red triangle appears.
I also tried to install a CWM recovery, but without the bootloader unlocked I got a "security error", that went away with a kdz update.
I searched this forum and I think I can't unlock the bootloader with a bricked phone, am I right?
I plan to make a last recovery with the LG Mobile Support Tool and send it to warranty, so that no trace of fastboot manipulations should be visible (right?).
I have read a lot of threads on this forum (and others) before posting here.
If you know of anything I can try, please let me know.
Thank you!
Absolutely the same...
I have this problem, too. Did you find how to fix it?
What happens during the recovery with the LG tool? I am sure I read about stopping at 90% and a solution somewhere here... search for it, I dont have the time, sorry...
Sent from my LG-P760 using xda app-developers app
i have the same issue .
at 90% phone reboots and red triangle dead android appears .
i think its a problem with the drivers . tried this on win 8.1 , 7 and xp on 2 different computers . same results .
i got the same with lg recovery and offline kdz method .
would be very nice to find a fix
I brought the phone to the warranty office. They substituted the "pcb main" so I believe it was an hardware problem.
Hello,
I got the same problem. Using the same methods and got no positive results.
Does someone solve this?
hello my friends. have any of you solved this problem?
i did exactly what op did, and no results.
I never had a red triangle issue. This probably neans that the bootloader is kocked AND encrypted. In the beginning this was the case with the US T-Mobile variant, and seemingly for all L9s from the final oroduction run. For other phones you needed to flash a certain stock rom, v10a or the first couple of v20s, then unlock the bootloader.
You should try using the CSE Flash mode from LG Flash Tool 2014.
I have the same problem, the difference is when i try to flash kdz it gives me error at 50%. I tried all the methods that op does but no succes. I also tried flashing img's manually from fastboot, i tried cwm and twrp as recovery.img and even extracted original kdz to img's and flash every partition manually. The system.img is the main problem cause you can't flash such huge file (1gb) through fastboot. Maybe someone have some idea is there any way to unbrick my phone? Bootloader is locked, and device had no root before brick.
After successfully rooting my first Android, I got excited and jumped ahead of myself and indulged into Xposed and then after Gravity Bomb. Just so all OT users know Gravity Bomb will most likely put your phone in to a boot loop!!
After surfing the net I came across a post on another forum by a user named 'Brka' and he educated me on a this tool. To quote him,
Hello all,
in order to keep this section clean, this is the starting point that will (in most cases),
fix your problem, and stop repeatedly asked question, like :
- How to reset my blocked counter ?
- I have a dead phone/tablet, what to do first ?
- My phone doesn't power on, what to do ?
- Please, I need firmware for OT-XXXX Model !
Now, for beginning, some explanation :
Alcatel (TCL) already thought about many user problems that can arise,
like screwed android system (ROM), dead phones, etc,
and gave a solution for fixing most common errors, mentioned above,
called ONE TOUCH UPGRADE a.k.a. O.T.U.
All you need to do is check your model, sometimes you can use model written on sticker,
like ot-985, or M'Pop (ot-5020) etc. (If it's branded model like IDEA Aurus - it's ot-985N),
and download corresponding One Touch Upgrade tool, via "googling" for that model,
or via search on official (or country-dependant) Alcatel site - EXAMPLE for OT-985
Now, after you downloaded and installed OTU, charge your battery,
use classic micro-usb cable and revive your phone, by following what OTU says.
OTU will install drivers, and after you plug your powered off phone,
it will found new hardware (Virtual USB COM Port), so it may give error at first try,
just simply repeat process, it will do it's job, and (hopefully), bring it back to life.
Some nice things that OTU will do for you : (all of them at once)
- It WILL bring your phone back to life (if software problem)
- It WILL FULLY RESET ALL User Data !!!
- It WILL Return Phone to Stock state, in case you used custom rom.
- It WILL Remove User/PIN/Google/Pattern Lock
- It WILL reset unlock codes counter (too many tries)
I hope all is clear now, regarding this case.
Posts containing mentioned requests for ROM's can be posted just and ONLY
in case you have ALREADY tried things from this post,
else it will be deleted / moved to trash.
This thread will also contain successful done phones via this method, to eliminate
the forum space / confusion.
wish you luck with dead phones,
b.r.
Alex

So if you didn't back up your phone properly and can't figure out how to reinstall the STOCK ROM, find the O.T.U. Tool on Alcatel's support website and you should be fine.
Excuse me po, can I use this even for alcatel idol 3 dead phone?
Hi hello
So here’s a head scratcher I hope someone can help me with that won’t involve replacing my main board.
Got myself the p20 lite (ANE-LX1 C432) - Single Sim.
I unlocked the bootloader with Huawei just before they stopped handing out the codes. All was good and happy with the world.
Rooted with Magisk and Was busy messing around With Termux, Linux deploy, Mobile Terminal and some pretty basic stuff. I’ve been out of the android scene for a while so was getting reacquainted with the scene.
Anyway. I was messing around in the terminal in a root shell just fixing basic permissions after messing up my termux environment as root. Phone randomly rebooted (I must’ve messed with the wrong folder -no idea which) came back on and my IMEI and baseband were gone.
No worries, I thought. Happened tonnes of times with my previous Devices (looking at you Samsung) just a quick restore or flash and all will be happy again.
Yeah, not quite.
Note that up until this point I hadn’t touched the system partition (probably besides the mobile terminal mishap -no idea)
So over the last week or so I have tried everything. Restore from Twrp backup. Flashed stock through fastboot, through erecovery. Those flashed ok but didn’t fix it.
Putting numerous different update.app FULL & OTA updates in dload folder on SD and internal all failed. Only used my builds version of course and only ones firmware finder deemed compatible/available
Then I got desperate (read: stupid) Decided to take the unpacked firmware files and flash whichever ones twrp would let me. First tried just the modem files. Didn’t help. Then just went through the list and flashed all I could.
I think the kicker came in when I installed the Trustfirmware.img because once I did that I rebooted and now I was stuck in an endless boot loop. No way to get into recovery. Not with their ton combo nor adb/fastboot.
I still had access to fastboot at this point at least and started doing every single thing suggested all over the net just trying to get back to stock.
Tried the unbrick option on The Huawei Multi-Tool. Flashed ok. Phone still wouldn’t boot. Did it a few times with 3 approved versions. Nothing. Only access to fastboot otherwise I was in a boot loop with error mode error no 15 and the verification failure (Attached below)
Last thing I tried after reading online was to relock my boot loader and flash stock. So I locked it with Huawei Multi-Tool. Reboot......
Now I don’t even have access to fastboot. My PC’s (windows and Linux) don’t even acknowledge it and holding volume down in all the weird and wonderful ways and times does nothing. All I get is startup Huawei Logo, Error Mode as per pic Below and then reboot. That’s it.
I’m assuming it’s trying to do a factory reset after relocking the bootloader (if it even locked properly, can’t check) but it can’t get into recovery/erecovery. I dunno ?
That’s my essay of where I’m at. Warranty is already void so not an option and I don’t want to buy a new mainboard (may as well buy a new phone).
So here I am. Is this my life now or does anyone have any magic tricks to possibly suggest?

Thanks for this.
The battery discharged fully about two days ago.
I haven’t tried plugging it in and out as/if it turns on immediately (though even though it shows dead without charger it still comes on immediately).
I’m gonna get a weaker lower amp charger and see if that maybe helps. Fml ?
***UPDATE***
Been at it for hours. Battery is completely flat. But h second I plug it in the the Black Huawei logo comes up ten a few seconds later it’s on the same error screen for a little longer then boot loops like that constantly.
The error isn’t the same as the post in that link though. And I am FRP unlocked.
Eh.

I guess your previous error was related to ramdisk...
Now what is your current situation?
-What error is showed in the Error mode?
-Can you reach FASTBOOT&RESCUE MODE menu?
-What is your current recovery?

As it stands I cannot enter fastboot or recovery mode. Update from SD also doesn’t do anything. Battery is completely discharged. And if I leave it on the charger it doesn’t charge, only boot loops.
So with all that the ONLY thing this phone does now is:
- Starts up Showing Huawei logo
- Error Mode Screen with Func No: 15 (bl31 image) & Error No: 1 (security verify failed)
- Reboots
Ths happens whether it’s plugged into the pc’s usb or the charger. Tried all combinations of buttons too.
It has stock recovery as I flashed that back when trying to revert back to stock.
I lost access to fastboot after I locked the bootlaoder again using the Huawei Multi Tool. It’s like it trying to do the factory wipe that it usually would after locking/unlocking the bootloader but is unable to due to the error mode screen.

I see, it is really bad
My last hope is to be able to do a forced Firmware upgrade. Press power button and VOL + and VOL- simultaneously. Do you see the same as the attached image?

Ah man, I wish it would even do that. It makes no attempt to even pretend to see the sd card update. If I hold all the buttons in it still only comes up with the error mode and reboots.
I popped it open and connected a charger up battery to see if that would help but it doesn’t.
Do you maybe know the pin layout on the inside or know where I could get schematics? Been looking everywhere.
I’m almost done building my own Jtag box and am hoping to bring it back to life by writing straight to the damn thing.

That is sad!!!
With JTAG and schematics stuff I cannot help you.
What I found recently and it was new for me (I didn't tested yet) is a possibility to install firmware via "dload" folder, but to start installation the stock recovery have to be full functional.
If I found something interesting for you I'll post here.

To my knowledge the recovery is installed. Well erecovery. It was working up until I locked the bootloader again and it went into a boot loop instead of doing the factory reset.
Is there any other way to force sd update other than with the dload folder?
Thanks for tying to help, I appreciate it.

You can check the official documentation about that.
Please let us know how you solved this problem.

Still unsolved as of yet.
I’ve finished building my own version of the Riff/Octoplus box as well as a makeshift Jtag. I’m still trying to find and piece together some firmware files and other board software I think I need.
Also, if anyone has any idea where the test point is on this board I’d really appreciate you pointing it out. I cannot find the schematics or any solid documentation anywhere.
I will attach the pics I have of both sides of the board as soon as I get home.

well, try to restore your device using dload method. It needs you to copy the UPDATE.APP in dload folder of an external sd card(formated in NTFS format) and then just press both vol up+down along with power button for a few seconds. It will auto launch huawei e-recovery and will try to flash the UPDATE.APP you stored in ext sd card. This should definitely work.
Dload method doesn't need you to unlock your device or bootloader.
Maybe?
I know it’s a long shot but I still have this phone. If anyone maybe knows if there’s been a way to fix this as of yet please let me know. ?
Lol. Still got this damn thing. Been searching around and seen a few people reporting similar errors. Never find out if they ever solve it though.
So. Anyone maybe have any knowledge to share? Anything at all.
I don't know if you still have your device, but I had the exact same issue with a P10 (VTR-L09)
I was able to fix fastboot using https://github.com/mashed-potatoes/PotatoNV
That tool was designed to unlock the bootloader, but I noticed that It actually flashes a slightly modified version of fastboot.
PotatoNV can also unlock P20 lite bootloader, so you should give it a shot.
Good luck!
If it works, you should be able to flash stock recovery image and then restore the system using the dload folder.
you can Repair it with Software Testpoint and Full Bootloader Unlock ,and then flash a Board Software via Software Testpoint, that helps 100%!!!
use this Firmware Download ANE-LX1
use the Software with logins and you have all what you need.
you must start the Software Testpoint so!!
VIDEO : how to start Software Testpoint P20 Lite
than in Software Testpoint you flash the included Board Software with DC-Phoenix and after that use the included dload update via sdcard and eRecovery mode and your Phone is running!!!
I would unlock the bootloader via Software Testpoint with DC-Phoenix, then the FBLock is unlocked and you can flash as you wish!!!! And the great thing about it is that you don't need an UnlockKey either, you can then read this with HCU client software, the only thing that's stupid is that you need a time-based license for the two programs, which you have to buy.
HCU client download
https://hcu-client.com
DC Phoenix download
https://forum.dc-unlocker.com/forum/modems-and-phones/huawei/155916-dc-phoenix
Since I accidentally bought a 3-day license twice and my P20 Lite is now completely rooted on Lineage 19.1, I can give away 2 access data, which are still valid for 2 days.
you can edit your smartphone with it.

Hello, I bought a used mi9t and knowing that it had a boot problem (this is what the seller wrote in the sale description) and naively believed that I would be repaired easily as I had already done before.
the mi9t starts but freezes after + - 5 sec and reboot and so on, so I do not have time to do a reset, activate develop mode, unlock the bootloader etc ...
I arrived started in recovery and or in fastboot, a wipe data does not change anything, I of course tried to flash via miflash and miflash pro etc ... but as the bootloader is locked, develop mode not active etc ... nothing did not work. I managed to flash once in recovery, assistant mi but it did not change anything although the attempt arrived at 100%, I tried this method again but it does not want to do it anymore.
it is in miu in V11.0.5.0.QFJEUXM so I tried with the following but without result.
Looks like Android isn't complete, I think the person who sold it to me missed the Flash.
there I do not know what to do, I looked everywhere on the net for a solution but found nothing so as a last chance, I post here and elsewhere while crossing my fingers.
thanks in advance
I tried all these rom but without result
and via miflash I have the error anti rollback check error
error sorry
Try china newest rom with fastboot
Hello People,
I was flashing the stock rom using mi flash but the flashing timed out after 2000 seconds. I rebooted the phone to fastboot but it failed and the screen went black. [Reason For Flashing: We lost the pattern lock so i flashed the stock rom and, then twrp, just in case to avoid losing the screen lock. But then i thought of keeping it stock and when i reflashed, the timeout occurred and phone went black]
Since then i have tried many different versions of MiFlash and even MiFlash Pro, however they are not successful due to authentication issues. I took it to the service center as a last resort but they are asking for motherboard replacement which i am not comfortable spending for.
I researched as much as i could and tried QPST flashing as well but learnt that a patched firehorse file is required. And that is not available anywhere on the internet.
I am not sure what options i have now or am i doing something wrong.
Could anyone please help me in reviving my phone?
NOTE:
Bootloader - Unlocked
PC Detects It as: QDLoader 9008
Regards
i will help you. pm me asap
SORRY CAN'T HELP YOU ANYMORE. Got no more credits on my Xiaomi Pro Tool account. If you want a cheap fix then it is your only choice. Anyway try any MiFlash below 2020 to flash stock rom. Good luck.
Try mi flash tool 2.0 by Francesco tescari it may help
Thank you for your replies. I had to get it fixed from a nearby shop who claimed to have some access to GSM Forum. I am not sure which tool they used but the job was done.
I wish a patched firehorse file was available. QPST would have helped in that case.
Thanks again.
