My phone is stuck on the android screen (X5)

I have ideos X5. I flashed B522. Next day, touch screen freezed. I restart phone and phone is stuck on the android screen(android animation). I tried to flash diffrent stock roms but "Update failed" in all of them. Can you help me, please?
Sorry for my bad English.

Does it fail on the first part, unpacking? or the second part?

it usually fail the second part. any ideas?

That's the issue I have too, it seems it is bricked because the bootloader is locked. I would recommend just getting a warranty repair on it. I was refused that because I have already had a motherboard changed and now they refuse to do it again.

I just found this thread today, but I am having a problem downloading the file.
If you can download the file and open it, you could upload it somewhere for me. I can try it out on my phone first if you want.

How to unlocked the pink screen? What do I do, now?

After you download it, unzip it and take the UPDATE.APP and put it in a folder dload and move it to your sdcard. Then hold vol+/- and power, let it flash. Pull the battery after it has restarted and go into pink screen again and plug in to your PC

Thank you for answer. But I put dload folder in the pink screen partition. Now, that partition locked. Version 2.3 installed now. I can't see the internal SD on my PC.
I will try it. I write the result.

Yes!!!! My phone works"!!!!!!!
---------- Post added at 11:21 PM ---------- Previous post was at 11:05 PM ----------
Ok here's what I did
Download mediafire.com/?1hbk6n46hgamyt6
Unzip it, and find UPDATE.APP
Put UPDATE.APP in a dload folder and upload to empty sdcard.
Put sdcard in phone, and hold vol+/- and power and flash it.
After phone has restarted pull battery.
Download http://www.mediafire.com/?6hrfz36b8e2vw87
Unzip and copy the dload folder to empty sdcard.
Hold vol+/- and power and flash it.
After it fails near the end or if it restarts then pull battery.
Download a rooted boot.img and a clockworkmod recovery.img (got both mine from links at modaco)
Attach phone to PC in pink screen mode and delete the boot.img and recover.img files.
Upload the downloaded root.img and recovery.img to image folder in phone.
Download any custom rom from XDA, I used http://forum.xda-developers.com/showthread.php?t=1475687 and upload it to sdcard
Pull battery.
Hold vol+ and power and go into clockworkmod, wipe everything and flash the custom rom!!
Good luck!

Try hisuite It's drivers are prefect

Yeah I think I have HiSuite installed already too so the drivers were from there.
You should only see 1 partition anyway.
But it looks like the pink screen is unlocked because before it says drivers not found when the bootloader is locked.
Try unplugging and plugging in again.

No I meant just for the drivers it installs.
Try again from the beginning, it should work for you.

Look for a file v10d_downgrade.kdz in the net, you have to flash that. And the flash whatever kdz you want
It wont work with other kdz.

It does not work, the KDZ throws me the same error. Look:

DELETED sorry wrong post

First of all reinstall the drivers on your computer
Then, did you try to remove the battery, plug the phone to your computer (without the battery), then try to start the phone in Emergency Mode?
If you get to the Emergency Mode with the correct drivers installed, you should be able to flash anything from KDZ.
This method was the only way I could get my L7 in Emergency Mode AND recognized by KDZ, so you could be in the same situation as me maybe?

That method never worked for me, did you get a "UpTestEX_mod2_marwin.exe" in the packge that you downloaded? Use that, select emergency and the v10d_downgrade and flash! (follow a tutorial, you need to install small http server before...... like here)

have u tried "vol down" + "power button"
and when buttons light up, press the "menu" button
and do it a couple of times?

Nothing I've read has worked for me, trying to read the information on the device I get this:

Hey friend. I have already almost lost my phone several Times.
But persistance is the best to resolve your problem.
Firstly ur phone isnt bricked as it turns on!!!
So try this:
1° turn off phone
2° bottom up + down + turn on
3° should apper "emergency mode" [if this didnt work, try And get in this screen"
4°flash KDZ ( MAKE SURE ITS ON EMERGENCY MODE ON KDZ UPDATER ! AND THE MOST
IMPORTANT WHEN YOU FLASH IT WILL POP UP SEVERAL ERROS . DONT DO NOTHING LET IT CONTINUE )
5° Phone will boot loop (resolve it making a HARD RESET (bottom down+ menu+turn on)
6° now it will reset everything. Then u must flash AGAIN KDZ UPDATER (BUT NOW IT WONT SHOW ERROS ON KDZ UPDATER )
Job done
Phone recovered
PM ME IF ANY DOUBT OCCOURS
Sent From ... Lg e400 <-- {[Brasilian Here]}

Enter in DIAG MODE vol up+vol down+ turn on
(Just do it IF -> u have tried my tip ABOVE this one.)
After that , make sure u connect ur phone then, flash in KDZ UPDATE.
NO ERROR . THIS MUST WORK FOR YOU . AND AS I SAID
IF IT DONT RECONIZE YOUR PHONE THEN U MUST HARD RESET IT .
Sent From ... Lg e400 <-- {[Brasilian Here]}

Finally I could fix the problem without using KDZ and now I want to share with the community.
1. Remove the phone battery.
2. Press the button '+', and connect the usb (without battery).
3. Wait until the drivers are installed on the computer.
4. With the program of LG Mobile Support Tool, and with the phone connected press "Upgrade Error recovery" within the program.
5. Let it download the rom, you unzip and install.
Note: All this process without the battery attached to the phone.
That's all

Bootloop on CMWR and phone never close, only without battery!
Hello.
Today i want to upgrade my android, and surprise! When i push "install"and phone is was restarted, is entered in a continuos loop restart directly in CMWR mode. Here, it was impossible to install anything or make any changes, only "restart", and again, the phone is restarting directly in CMWR mode. At first I thought I bricked my phone, because even in emergency mode it could not start
BUT all this is madeit with battery inside!
After reading what was written here, I realized that I have to remove the battery, and surprise, on the second attempt i managed to start in emergency mode! (with usb cable connected to PC! ) :laugh:
Good...
Now, i openet the "LG Mobile Support Tool" (with usb connected to PC), and after LG mobile tool i let to check and install the last version of USB drivers , it was able to communicate with my PC. After that, i installed the latest available version of Android, via LG Mobile Tool and now is working.
BUT i lost the root of the phone. Anyway, it's the phone of my wife, and she's not interested in "walked" through it
Thanks to "andersonlima" , i understand that as long as boots, is not bricked !
Good luck in the future, and most importantly, read well, with calmness, that can occur various ideas, along with what you have in face, may lead to solving your problem! :good:

LG G2 D802 stuck on gray lines

So when you turn it on your phone after turning off you don't see the LG screen but only the lines? or only in the recovery?

Try entering download mode - poweroff the device -> hold volume up and connect to pc. Then try flashing your stock firmware.

Just tried that - it switched the phone on - the lines moved around again then settled into the screenshot.
Do I need the drivers installed on a PC for this to work? I tried it on a mac with Android File Transfer.

You need windows + lg flash tool 2014 + your kdz, drivers would install through the lg suite.

Unfortunately I can't get to the dialer to get my IMEI. I know they used to be under the battery but thats obviously a no no on the g2.
Regardless, I found the .kdz here http://storagecow.eu/index.php?dir=Xda/LG+G2/Stock/Hong+Kong+D802/
Installed the drivers, LG Flash Tool 2014, attempted to put my phone into Download mode (The phone has the grey lines in different places) but the PC still doesn't recognize the phoen when I plug it in and the flash tool cannot read the phone also.
Any other suggestions please? Thanks.

You may also try the tot method.
Can you recognize if the image behind the lines is small (centered on the screen) or a larger one ?
Because it might be that you've got blue circles, which are shown prior to entering the actual download mode..

I don't actually know if its going into download mode or not. I've taken another photo as below which shows what my phone looks like when plugged in, the lines move around like an animation to start of with then settle in this position - there isn't actually anything behind the lines. It's almost as if the screen is messed up and the pictures aren't displaying correctly. I seriously doubt it is a hardware issue as it was working just fine before using AutoRec.
Just so annoyed at myself for doing this so soon after I got it -_-

1. power off
2. hold volume up and connect to pc
3. flash kdz

or just connect to pc if it doesn't boot, see if there is some device in device manager that wasn't there.

Iam facing the exact same issue right now
Phone was already soft bricked. user to get stuck at the lg logo and download modestopped working , volume + power would bring fast boot so i used adb command prompt and flashed boot,aboot and recovery files and then did a reboot and all i have are these moving gray lines
IF anybody resolved this issue please help with the steps

I have a same problem. Please help me, please !

Where did you buy the phone? Some online sellers combine parts from all variants and sell refurbished phones under D802 so when you flash it bricks your phone.
Do you have IMEI on box?

Same thing happened with mine. Got it fixed for 20$ through Jtech service.
Beware people.

I have same problem here. When connect via USB, Showing in device manager as Android device. But not showing anything under COM port. I tried to flash via LG flash tool. But flash tools fail to connect device. please help me to solve this. I am a Sri Lanka. If you a place to repair my phone. Please advise.
Thank You.

Same thing happened with me when i use autorec, lines on the screen but the phone work normally, receive calls and messages, the touch works normally, every thing work normal but there's no screen output or colors only gray lines wuth black screen. I think it's a refurbished phone with a different board that written on the cover, and we use the wrong autorec according to the board.
I don't know how to fix it. Any help ?

This is probably driver issue, remove LGUP, drivers and all the LG software including registery entries. Then install LG driver and LG Bridge, your device should get detected by LG Bridge.

LG G2 - secure booting error after installing SuperSU

Hi guys.

The only reason is the wrong version of SuperSu. Maybe I use custom made SuperSu for OnePlus 3T.
Before I flashed that SuperSu Zip file using TWRP there is no such problem. Only after flash SuperSu cause this issue .. ?
Before this flash, LG G2's is a new fresh install custom LineageOS for LG G2. Everything is OK. Only no root access. TWRP already installed.
LG G2 still can go to Download Mode as shown by holding the power button and connect USB cable to PC. But the problem is the PC & laptop cannot install the required driver properly. I think I've tried installed/reinstall all the suggested drivers but to no avail.
I even cannot enter the recovery mode using the key combination. When the phone is power on, it will continue to show that Boot certification verify alert.. Ermm ...
Just now just praying PC / laptop can detect and use tools installed on my computer to get to boot into the recovery mode. But is it still possible?
Or this totally means that I will never can use my LG G2 anymore?
Thanks guys.

wtf same thing happend to me

This happened to me too once.
Security error normally means that you should have flashed bumpboot.zip after supersu.zip.
You should still be able to get into TWRP (PWR+Down until Logo appears, then Up+Down).
Some LG drivers seem to miss something. Try older versions or alternative generic ADB drivers.
TOT method always worked for me in the end.

Install SRK Tools to fix boot partition. After that, you could enter in download mode easily.
Edit: LinageOS have your exclusively SuperSU. Next time, install the proper version in lineageOS Website. That problem happen to me, same problem...

Thanks to all.
But whatever fix you suggested, first the laptop/PC needs to detect the phone and install the driver correctly first right?
That is where I'm stuck now.
Even my office laptop also have the same problem, cannot install the driver properly.
Any help?
Thanks.

I've already downloaded this before.
But I could not find the option you mentioned.
Can you please guide me more details.
And if the laptop still cannot recognized my LG G2 properly, can I still proceed?
Thank you.

Latest status at my office laptop...
I have tried numerous drivers but to no avail.
Any help?
Thank you.

I mananged to get into this when I let the phone boot with a totally blank and black screen...
Any help with SRK Tools in this case?
Thank you.

Thank you so much guys.
Yes this SRK Tool is really amazing - https://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076
I can now get back into recovery mode and most importantly my computer can detect my phone!! Thanks a lot.
But now it seems that my Lineage OS has become corrupted and I don't think I want to install it anymore because the display is very poor in brightness.
So my next question is with such condition ie improper Lineage OS installation on the phone right now, how do I get back to the latest stock OS.
How do I start?
Thank you so much for the help.

After flashing SuperSU do as @MB525 suggests, flash Boot Image Bumper/ bumpboot-v1.0-blastagator-signed.zip

This needs to be done with Magisk too.

Same thing happen to me
