[LG Optimus L9 P760, P765, P768, P769] Gainder:
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!

I have this problem, too. Did you find how to fix it?

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.

Does someone solve this?

[LG Optimus L9 P760, P765, P768, P769] lecorbusier:
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.
[LG Optimus L9 P760, P765, P768, P769] facuarmo:
You should try using the CSE Flash mode from LG Flash Tool 2014.
[LG Optimus L9 P760, P765, P768, P769] maniecznik:
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.

Hi my device was supplied by carphone warehouse uk and when i got it thought it to be sim unlocked only to find a European sim lock exists

cant root cause it's mj7/mj4 ?

so can anyone recommend how to unlock it as i am travelling to India in the next week

any help or advice would be appreciated
[Galaxy Note 3 Q&A, Help & Troubleshooting] xclub_101:
I think you need to contact carphone warehouse uk or samsung uk and ask for a code. Other than that you can also root with kies 0x1 and try regionlockaway, but I would first try to complain to carphone warehouse uk and samsung uk first. Whatever they tell - TEST IT FIRST (insert a non-EU SIM in the phone while you are still in UK as a test).
[Galaxy Note 3 Q&A, Help & Troubleshooting] tkwish:
Carphone warehouse completely unhelpful

where would i obtain a non European sim? at this stage don't want to root and trip knox is there any proven and trusted code providers?

I'm not sure what you mean here mate. Do you mean you have a region lock or network lock. If you can use different sims like Vodafone, ee, three etc.. and you had a socket on your phone saying it's region locked then if you been using the phone with an uk sim then it should technically have the region lock removed. (Not always the case) if you can't use different sims in the uk already then you have network lock and can get a code to unlock by calling up the network provider

[Galaxy Note 3 Q&A, Help & Troubleshooting] alom5:
Just stick a different sim in to check. But souls to me out had the region lock. Which should be unlocked according to Samsung sheet you user it with a durian provider for a few calls. ... Only way to check is get a sim from different region. Sure you can buy froom a shop or something
[Galaxy Note 3 Q&A, Help & Troubleshooting] tkwish:
just been on the phone to samsung uk

they tell me all i need to do to unlock to use outside of europe is with the sim provided have a 5 minute continuous conversation from the handset

from then on it will be unlocked guess i'll have to wait and see

[G2 Q&A, Help & Troubleshooting] JelloSS:
Rooted my LG G2 (ATT) recently. Yesterday i got an error on bootup stating that system UI has crashed.. After that all hell broke loose. Phone when powered on only boots into the TWRP, friend thought he could "fix" the issue by doing a format on the device.. FML. SO now when trying to get into download mode to perform the Stock Rom/Unbrick process it just won't allow me to do anything. It just keeps booting into TWRP.

My laptop has all drivers needed, but phone won't be detected by my laptop..

Anyway how i can get my LG back to stock & working? Didn't have a custom rom or anything, only the Camera Mod which never gave issues..

The system UI came on before i did the Camera Mod by the way..

[G2 Q&A, Help & Troubleshooting] letschky:
Copy a Rom on a USB stick and install it in TWRP via OTG, run back into TWRP and enter this line

start at the recovery, go to Advanced, then Terminal Command, press Select,use this code,

dd if=/dev/Zero of=/dev/block/platform/msm_sdcc.1/by-name/fota

That should solve your problem, for me it just works

Only in this way can be turned off Trwp as default and the phone boots normally

Good Luck!

How am i going to get the ROM from a USB onto my LG G2? Cause my pc can't pick it up.........

& yes i have LG Drivers installed.
[G2 Q&A, Help & Troubleshooting] bean373:
Have you tried to use the "sideload" option to see if you can load a rom onto it yet? This requires that your computer sees your phone with the correct drivers and adb working too.

Did you try to do a complete wipe/reboot and see if you can get into download mode?

If none of those methods work then I'm not sure what to tell you. I ran into two problems only so far.

First one was when I accidently wiped everything and had to sideload a rom onto my phone.

Second, I took the OTA update and had the bootloop TWRP problem which was solved by using the LG Flash tool to flash the stock Sprint rom onto my phone by following the directions for the Verizon Method but used a Sprint rom and dll file.

If you can't sideload a rom or get into download mode then you have a major problem there but it could be just that you've overlooked something.

Copy a Rom to Usb and install the Rom via Usb/Otg Cable,it is self to install from internal Storage.You can Select OTG or internal Storage in Recovery to install the Rom.Its easy,I can Backup or install Roms on Otg.

[G2 Q&A, Help & Troubleshooting] heyazzo:
He got out.

I was stuck in the bootloop for about 6 hours before I realized I had the correct dll, and tot file, the correct utility from LGE, and I turned the noodle of a brick into a "unbranded" phone temporarily, until sprint came to the rescue, and branded everything back from the production image I loaded just earlier. I just wanna say this... DO NOT PLAY WITH PHONE DIALER CODES MEANT FOR THE KOREANS WHO TEST YOUR PHONE!!!

You can brick that **** fast as hell. TWRP kept coming in, and I didn't know how to deal with adb sideload, or the basic dd command to get things back to download mode. Now I have a real working knowledge of recovering from an otherwise hopeless state. Take your time, and explore slowly.

Your mileage may vary, just sayin'
[G2 Q&A, Help & Troubleshooting] jcal321:
This is not working for me I still get redirected right back to the recovery screen , none of my backups will work either, they say successful at the end but when I reboot I am right back to TWRP recovery once again.
[G2 Q&A, Help & Troubleshooting] htcm7:
I experienced this situation for a while.

The solution is doing a normal procedure to install custom rom from USB.

Just copy custom rom to USB, choose advanced wipe, then wipe dalvik, cache, data, and system. Then install custom rom in USB, and, reboot phone after installation finished.

Phone should be back to normal again.

Hi,

I'm kinda stuck here and maybe someone know what I'm missing here.

I downloaded the 2.8.7.102 WWE Rom and installed it without any problems. I used aWizard to backup the OS and reverted back to the Qtek_9100_RUU_Prodigy_10107105_Qtek_WWE Rom and modified the Extended_ROM to my likings. I tried to use aWizard to restore the 2.8.7.102 OS for several times now (without problems or errors) but it always hangs at the splashscreen so I have to restore a RUU Rom again to get my device to boot again.

What am I doing wrong?

Is what I want possible?

Thanks in advance on any help :)

Cheers,

Cacti
[8125, K-JAM, P4300, MDA Vario Software Upgrading] ahlok_hk:
I have tested what you want to do in my Wizard and success without any problem.

Please make sure you have unlock CID using 'u' and enabel RAPI using 'e' option.
[8125, K-JAM, P4300, MDA Vario Software Upgrading] Drifter:
Hey Cactus,

Did you get an error while flashing your device or is it when you are restarting it after flashing?

Have seen it with mine that during the first steps of the flash I got this error but when I flashed it on another computer everything went fine.

Cheers,

Drifter
[8125, K-JAM, P4300, MDA Vario Software Upgrading] le_cactus:
Drifter dude!!! Whazup :)

No errors when I run the RUU Rom and no errors when I use aWizard. But it hangs at the splash screen.

I did enable RAPI and I CID unlocked it also (although I'm sure you only need to do that once) but still no go. I reverted back to the RUU_Prodigy_1060204_105_11210_TMO_UK_Ship OS.

I can't stand that it's not working so I ran the RUU with the test ROM again and used aWizard to extract the OS rom again. You never know, it may have gone wrong the first time, but still no go. I was able to restore it's Radio Rom fine but not the OS part. Bummer!

Oh well, seems I need to be patient and wait till someone figures out how to unlock the locked Extended_ROM from newer roms.

Cheers

Cacti
[8125, K-JAM, P4300, MDA Vario Software Upgrading] rdef:
sorry you're having problems. The silver lining is that you can revert back from the 2.8.7.102 rom. Now, I feel comfortable trying 2.8.7.102, since i can go back.
[8125, K-JAM, P4300, MDA Vario Software Upgrading] Drifter:
Sorry Cactus, cant help you with this one.

If you have removed CID and simlock you shouldn't have any problems updating the firmware.

Did you try the update with another computer with a clean ActiveSync?

Someone else with a suggestion about this problem?
[Galaxy S II Q&A, Help & Troubleshooting] real_scree:
Hi All,

When I bought my phone it was locked to a network, I rooted it and installed an insecure kernel using Odin but do not believe I installed any custom firmware at that point, my phone is currently as follows;

Samsung gt-i9100

android version - 2.3.5

baseband version - I9100NEKI2

kernel version - 2.6.35.7-I9100XWKI8-CL616395root@DELL149 #2

build number - GINGERBREAD.XWKI8

I have SuperSU installed

When I boot into recovery it is Android system recovery <3e>

I do not believe I have CWM

I have recently tried to update using Cyanogenmod and Revolt files/guides here on XDA, the latest file being revolt_i9100-ALPHA-20131011.zip however i get the same message on install of;

E:failed to verify the whole-file signature

E:signature verification failed

After quite a bit of reading over the past week I now think the following is what I need to do but could do with a sanity check from you guys first before I end up with the proverbial brick. :(

1) find and install a version of CWM suitable for android 2.3.5 (all I seem to find is for android 4.x.x?)

2) using Odin flash a new kernel that is suitable for the android version I am trying to install

3) boot up CWM and install new fw ROM from SD card?

If anyone could confirm or correct any of the above it would be greatly appreciated :highfive:
[Galaxy S II Q&A, Help & Troubleshooting] MistahBungle:
Or you could make life easy for yourself and:-

1) Update to ICS or JB stock firmware; download a stock rom from Samfirmware (doesn't matter which given you're going custom next; just not 4.0.4) & flash with Odin following the instructions in the thread stickied near the top of Q&A (the one titled '[GUIDE][ICS/JB] 11/03 - Flash Stock firmware/ROM + Root...')

2) Root your phone (which will also give you CWM) following the instructions in the same thread

3) Download your custom rom of choice & flash with CWRecovery

Edit - P.S, in future, please don't double post in multiple fora (I'm referring to your posts yesterday).
[Galaxy S II Q&A, Help & Troubleshooting] real_scree:
356 2992548

That's great cheers, I've read that guide and all seems pretty straight forward.

Just to check, my phone is currently rooted (yellow triangle on start up), It's ok to follow that guide from its current state?

As for yesterdays posts, apologies I had many tabs open from reading different threads and admittedly got a tad lost in the site, hopefully if this all goes well i wont have to bother anyone again ay ;)
[Galaxy S II Q&A, Help & Troubleshooting] MistahBungle:
You need CWM rather than the stock recovery you obviously have. To get that, you need to flash a custom kernel, as recovery is baked into the kernel on the SGS3 (any recovery you flash independently of the kernel will not be permanent & only persist until the next reboot).

I strongly suggest you do all 3 steps.
[Galaxy S II Q&A, Help & Troubleshooting] real_scree:
once again thanks for the reply.

I have every intention of following all 3 steps, i'm currently on SamMobile searching for the firmware now, although the search options do not seem to have my operator on there, they do have an option for o2 and giffgaff run on their network so can only hope thats the correct option lol.

(gone for this file)

Model: GT-I9100

Country: United Kingdom (O2)

Version: Android 4.1.2

Changelist: N/A

Build date: Thu, 01 Jan 1970 00:00:00 +0000

Product Code: O2U

PDA: I9100XWLSD

CSC: I9100O2ULS7

MODEM: I9100XXLS8

DOWNLOAD: Terafile Rapidgator

My only concern is that my phone is currently rooted, has an insecure kernel on it and has been sim unlocked, once again excuse the complete noobishness (I am starting to get a grip on it all i think) but the guide seems to read for those who wish to perform those steps as well as update their firmware.

If you could just clarify that in my phones current state, and, once I have my stock rom from SamMobile that I'm ok to follow that guide from the start I think I'm good to go :highfive:
[Galaxy S II Q&A, Help & Troubleshooting] MistahBungle:
The guide is broken down into sections. You can do one/a combination of/or all of the procedures in that guide depending on what you want to do with the phone.

I've already told you what to do, up to you now (I don't repeat myself; I find it tedious).

I'm on stock 4.4.2. I can fastboot flash CWM and flash SuperSU in recovery. When I boot, SuperSU says there is no su binary. If I reboot into recovery, it's the stock recovery.

[Nexus 10 Q&A, Help & Troubleshooting] abdel12345:
Try twrp. Also It looks like you might just be booting recovery and not fishing it. Though that doesn't explain why you lose root.
