I know it will be better to do for all partitions, but I must first learn how to use some disassembler, then what i look for and so on.
I see messed up picture instead logo, so there is big chances to recover phone. Flashing kdz write system, kernel, recovery, etc. and (now) logo (without properly logo-no boot).
Anyway, dont hurt if try.

what lg mobile usb modem driver does?

If it's not getting in Emergency and not powering on and if you plug in Ubuntu and do lsusb in Terminal and there is GOBI MODEM it's a hard brick.

[Q] Hard brick - ZTE Kis 3

Hi. Recently I have made a very stupid mistake trying to load a custom ROM to my ZTE Kis 3, which resulted in a hard brick. The phone doesn't turn on, even into recovery mode, ani in Windows Device Manager is seen as "QHSUSB_BULK". Is there any way to unbrick it? I have the stock ROM, but I see no way to flash it into the phone... Can someone help?
Are you able boot into bootloader?
No, it doesn't boot any way.
If you have Linux installed on your computer this should work.

Thank you very much, I'll try this method.
Did you try?

No, because the phone doesn't even go into fastboot mode... Nevermind, I got a new one, it was kinda cheap.
Maybe the Open C Upgrade Tool would have worked, too.

Hi xerxes931, QHSUSB_BULK suggests it is TPT mode, which is a mode ZTE uses to recover devices using a windows flasher, apologies for replying to an old post but it is still recoverable if you still own it.

Than you very much, it's a great clue. However, I can't find files or any instructions on unbricking this phone, all I find is for ZTE Blade or ZTE Open...
Edit: I found this program - is it it? Can I just simply plug in the phone, find a stock ZTE Kis 3 rom, select it's directory and click "start all"?

The upgrade tool doesn't recognize the phone, it's saying "searching devices, please wait"... I guess I have to do it on a PC with a COM port? If yes, what cable to use?

Unable to find phone in Emergency or Recovery mode during KDZ flashing

Hello friends of XDA, i'm here to ask you help once again! This time the problem is about a mysteriuos p760 aka LG Optimus L9. The problems in which i came across is the unlocking the bootloader and installing a custom recovery.
I tried so many ways that i'm really out of resources and ideas... Here few screenshots of the phone informations from setting app:

I am using Windows 8.1U3 on an Alienware 17.
I'll try to explain as fast and clearly i can:
First i read about this thread and it simply didn't worked (wow totally unexpected thanks to my fortune (Y)).
Then i thought i could easily flash some KDZ with unlocked bootloader and a sparky CWM built in, so i've google a little around and i found this and I then tried to flash the
with this guide but here the fun begun! No matter how i installed drivers, rebooted the system, tried in recovery mode or S/W Mode, the software did not see any phone at all; on the contrary the device manager sees it clearly and install correctly the drivers.
After posting the errors i found an answer a month later in the same thread.
This guys advices to use this tool instead, but as you can guess from me writing here, it did not work.
Then googling again i found this guide where you can install a CWM without even unlocking the bootloader! So, hey, i just need the root!
So let's go finding some way to root this F device (may LG go bankrupt now)! Again i googled "root p760/l9/optimus/plslgdie" and i found few ways none of them working. The Saurik one tells me that there is no bug available to exploit, the Chinese all-in-one rooter seems not having any green button and other script based on adb simply do not find the phone!
Of course i've tried a lot of cables and computers, all of them not working (still i need to try another OS....) and i'm going crazy. Only another device drove me crazy like that (the e610 aka L5 - wow this too was totally unexpcted!) but i finally found a ways to solve.
Please help me to delete every single line of code LG compiled in this device, please!
Up! Halp pls!

Well no need to apologize, you did not offend me i installed the latest from the site, exactly the LGUnitedMobileDriver_S50MAN311AP22_ML_WHQL_Ver_3.11.3. Furthermore i even formatted the PC to try this because i thought that some Nexus drivers could have messed up with them!

@Rammar515 do not abandon me please :crying:
It's hard to say. I remember some people told me that windows 8 have problems with l9 driver. I don't want to say that you can reinstall drivers, because I'm sure you did it a few times. You can always install windows 7 but it's derp idea (of course if you want, you can do it). Did you try to run official LG recovery program and try to install from it?

Never tried from the official software, but tomorrow i will try both XP SP3 and 7! I fund an old rusty laptop with 2GB ram and a Pentium D! I'll format it until drivers will work :silly:
Ok now i even tried Windows 7 and still nothing.... What's wrong with this phone? It makes me want to kill Bon-Moo Koo...

The same thing happened to my d686, just send it to a LG service with your warnity, it's best not to tell them it was rooted. Just tell them this happened after updating thru LG Mobile Support Tool. They will change the phone's motherboard. Here, in Romania, this worked!

@muehLe82. I also have h960a 32gb European version bought from Czech Republic. The problem is that the Turkish version of marshmallow is not supported by European model. Whn u try to flash it the system detecting as a incompatible version maybe something to do with regional country based lock set by lg. The solution i can think of it is you need the original firmware kdz for the German version and try flash it and see what happens. I didn't find on xda any original firmware kdz file for European version. I m still a newbie so maybe someone else have better solution.

Hi,
as I´m not able to enter download mode, a different kdz or tot-file wouldn´t help I´m afraid
@muehLe82 instead of using lg UP. Try using lg bridge software and see if it enters download mode. Pull out the battery for couple of minutes and try entering download mode using lg bridge software and see if it detects ur phone. I understand your frustration completely as i was also tempted to flash the Turkish kdz update on my h960a model. At last minute i decided not to as i thought i spend so much money on a new phone and marshmallow isn't something huge update to take the risk.,
same boat
im on the same boat. Patience is a virtue but hey im in this now. Ive tried ADB, LG PUP and LG Bridge. the issue i think is that the phone is not detected, ive installed the drivers but im getting a device descripter issue on device manager. If I can get ADB detect the phone i could probably re flash it but i cant turn it on nor can I put it on download mode.
any other ideas before i send this to service center of LG?

Since you want to keep your data, try to get into download mode and flash a kdz.
If that doesn't work, I'm afraid you are gonna have to do a "hard reset" (factory reset/data wipe).
May you provide me with a good tutorial for doing it?
Here is one: https://forum.xda-developers.com/showthread.php?t=2797190
If it doesn't work, just use Google to find another one.
I will tell you about the hard reset, if you want.
I am problematic - and some alternative because I cannot install stuff on this PC - some portable version of LG drivers? I cannot find

Nope.
Get an admin to install it.
No way around it.
Unless you want to try the hard reset, which doesn't need a PC.
But you will lose all your data.
Sic! But on the downloaded mode, it's writing unrooted user b13>?
Sic! But in downloaded mode there's info that it is unrooted user b13>?

Even better!
That is meant for LG's engineers to see if your phone is rooted when you sent it in for a fix under the warranty.
If it says rooted, they will mark warranty void and won't fix it, unless you pay them.
Anyway, it let's you flash no matter what it says there.
So go ahead and flash the kdz.
Okay, cool for me.
I already started it but
1st I am not sure which version I have, can I check it somewhere
2nd the tool shows that my phone is disconnected

Make sure that the cable is good.
The older it is, the more likely it is to cause issues during data transfers.
My suggestion?
Get a new one.
Or, you could borrow one from a friend, but make sure it works on data transfers, not just charging.
I made 2 kdz flashes but the phone still bricks. Rescue data, but all in all install Lineageos- CM RIP. Thank you!
