Hi everyone.
I have an LG G Flex 2 (H955) that suddenly went on a fritz. It used to be rooted fine, it was on default firmware, 10 something (wouldn't OTA due to rooting), no issues, but as I am a heavy user, enabled multiuser, had a bunch of apps installed and running it started to slow down on occasion, but nothing unexpected. Anyway, few days back, it shut down on its own while I was typing a message and the phone entered bootloop - on it's own. I decided to cut my losses and did the factory reset the hardware way, it booted up, did the "optimizing apps thing", got to welcome screen and - froze - then just restarted. It's been doing that ever since. Sometimes it boots all the way and then freezes and starts, sometimes it gets stuck on LG logo, sometimes even boots and works for a minute or two but still freezes and reboots.
I can access Download mode, and HW factory reset. I flashed several stock ROMs I found with LG flash tool 2014. It goes without a hitch, boots up, again gets to the welcome screen and reboots. I tried to to the dd cmd way to flash the only system.img I found online, but I get a security error at boot. It gets fixed when I flash the stock ROM again with flash tool. I am at my wits end. I have no warranty, I have no backed up original dump. With my limited knowledge I have somewhat of a hunch that one of the partitions might be corrupted as it boots most of the time but as it tries to write or read something from somewhere (hence showing the Welcome screen) it dies.
Would anyone have a suggestion as to what I might try next, or had a similar experience?
Thank you all very much in advance for any help.
Have you tried this tool with the appropriate image?

Hi and thanks for the tip. However, no, I have not tried this method as my device is H955, International version, and I am not keen on messing up the phone worse then it already is.
I will look it up in more detail, but as far as I can see it only pertains to the H950 (ATT version)
Edit: I looked it up in detail, and the developer removed the H955 support as there is a KDZ for it and he claims the .kdz is a much better option - however - .kdz does not work for me. It flashes the rom all right, both in Normal and CSE Flash modes, but the problem persists. Turns on (if I'm lucky), freezes, reboots and so on.
D'oh, didn't see the H955 part. :-|
Sorry to hear you are still stuck, can't offer much more unfortunately.
I know one of the flashing modes does a reset, but maybe a reset after the flash might help.. i think it's, from powred off, down plus power until the lg logo then release and then hold power on its own until you get to a recovery screen where you can reset.
you probably already tried that I'm guessing though. taken memory card out if you're using one?

Hi and thanks for yet another tip. However, you guessed right - I tried everything - reset from the recovery, before the flash, after the flash, in the middle of flash, with memory card, without memory card, tons of times - you name it, I've tried it. And still, it boots up (sometimes, though), freezes and go bye-bye. I'm completely out of ideas. If I could somehow rebuild partitions from Download mode, or use ADB, or push some image I found and flash it directly, but there is no way to push files to phone in Download mode (and 5.1.1. disabled external memory, so that is out of the option too).
It seems I'm stuck for now. I'm wondering if the repair guys have some tricks up their sleeves, perhaps with those hardware boxes, jtag something or other...
im on same boat with h955p, any solution?
the battery is the problem 100%. i had the same problem and i managed to fix it with buying a new battery and replacing it. 10$ on aliexpress plus you get the tools and it is really easy to replace.
hi. i was stuck in this situation. you can reflash the original stock rom back from LG UP software. at me this was the problem. my friend have a korean model and at him the 4g data connection was the problem...i was on the update of the marshmellow and freeze and reboot...factory reset didn't do something cool and keeps rebooting...but i was smart and lucky and my brain was thinking at the reflash of the phone...so i was to the reflash so my phone was completely and fully functional...no freeze , no reboot...and look for the v20a italy firmware (stock rom)...i say this because this v20a italy rom is so f***in stable and no battery drain...better than other stock rom marshmellow. Thanks me later.
Hi everyone. A friend of mine gave me this falcon to revive.
He just unlocked the bootloader and never booted again. When it starts, it gets frozen after the world bootanimation in this retroiluminated black screen.
When i go to the fastboot screen and reset the device to factory state, the phone stays the same. When i go to Recovery mode appears there's no command. And i got to press power+up several times 'til 'Recovery' pops out. But when it does, none options makes any difference (factory reset, cache and data user reset, etc).
I tried to push a rom or install with adb from this recovery, and tried to install a new rom in fastboot. No matter what i do, it always stays in this black screen after the bootanimation.
I left it turned on for a day and nothing, i charged and nothing, i try some other versions (5.0, 4.4) and nothing.
If there's something that isn't clear or any question and solutions, tell me.. i will give you any information. Thanks.
Thanks all for reading and please help!.
Hi there, my mother have an XT1033 and some days ago the phone got bricked in a black screen. I don't know what she was doing when it happened, but i know that the phone have its storage almost full, maybe this is the cause.
But the problem is that i tried to do a hard reset, but got an "Boot up fail!" trying to access the Recovery.
So i tried to unlock the bootloader, aparently it was succesfull since i could access the Recovery. But the wipe data/cache option solved nothing and aparently no data was wiped.
I tried to flash a new recovery, got the "OKAY" output but the recovery stills the same. Tried to flash a stock rom and still nothing changed. And actually, for some reason the phone did a successfull boot after all this, and was still with the old system, with the same data as before, and spamming error messages on the screen untill going to the black screen again.
I tried almosst everything, someone have some tips?
And sorry, english is not my first language.
I found the phone in my bag with a discharged battery and does not want to boot all the way. It shows the animated MIUI logo for about 1 minute and then restarts, sometimes showing the menu to switch to 'wipe data' and 'assistant'.
It's all stock, locked, up-to-date, I think still on Android 10 or which one it is. I did not install any new apps and don't even use the phone for anything other than gaming.
I've tried connecting with PC Suite but it doesn't see the phone. Fastboot anything does not work since the bootloader is locked. I know I can wipe data and be done with it, just wondering if there is anything else I can do.
EDIT: I've wiped the data and reinstalled the phone but would like to know if there is a way to avoid this in the future.
Unlock bootloader. This is very important. Then you have full control over the device.
For example the other day I had hard brick because fastboot flash was interrupted. And I still managed to unbrick the device thanks to unlocked bootloader and custom recovery.
It's really hard to hard brick this device. I love Xiaomi <3
Hi everyone.
Last night my phone ran out of power and when I charged it back up it wouldn't boot at all, so this morning I decided to try and fix it but I think I have just screwed it up even more to the point that its completely bricked.
I could still access TWRP and tried to reinstall the firmware and flash TWRP through the checkbox execpt about 1 minute in the screen went off due to the time out, but the screen wouldn't come back on at all so I left it for an hour just in case if it was still running in the background, after this time I hard restarted the phone and entered TWRP again and but it didn't install the firmware properly and my computer wasn't reading the phone properly so as a test I tried to swap bootloader from A to B stupidly and now I can't seem to access anything, only thing I can do is the menu where it says start, power off, recovery mode and restart bootloader. Pressing any of these settings seems to just put me back in to this menu again.
When plugging in the phone in to the PC it make's no noise at all as well.
Have I completely hard bricked my phone? Or is there a way to fix it?
Thanks Ben
All fixed I flashed the RAW firmware
