[Q] Phone is stuck at android logo

My phone wont start up... It stays at the android logo.
I did Vol. down + power on.
then KDZ_FW_UPD and reflashing with the rom but it didnt work. AFter the phone restarts by it self it still stuck at the android logo.
Help me
Type: 3GQCT
PhoneMode: DIAG sometimes i try cs_emergency
Version: nothing
I disabled the android modem
I don't really know which rom it had but i am trying some roms. I baught the phone in carphone warehouse in England (UK in summer 2010.

when your phone stucks on android logo,let it be at there .. connect phone to the computer and try to flash with kdz updater again. (my computer finded phone then [adb device] )

i tried that but after the phone restarts by it self it still stuck at android logo

Try it again and again in cs_emergeny or in standard emergency mode. Delete all LG drivers, boot your device and connect it to your pc. Your Windows will check for drviers and updates automatically. After installing the drivers u can reflash your phone without any issues

what rom you have installed? do you have fastboot or recovery installed there ?

I tried many roms. I tried fastboot,recovery but it still stucks at the android logo after the phone restarts by it self..

before all this hapend i installed app2sd then my phone went very slow and got frozen after i restarted it got stuck at the android logo.

anyone know?

The only thing I know is that I had the same problem...
I tried to flash a UK Vodafone ROM on my NL Vodafone phone, and apparently that didn't work...
The only thing that worked for me was starting the phone into download mode (Volume down, home button and power button, if I recall correctly) and then installing the 2.2.1 OpenSwift ROM via Windows Enabler and KDZ_FW_UPD.
Good luck!

1- Hello you need Press VOLUME UP + HOME + SEARCH buttons, you see the lg logo
2- update wiht Clockwork recovery rom.kdz
the phone started.. you need remove the battery.
3- Put the battery again and then press Power Button+ Camera you see LG logo but whait the screen black its recovery.
Flash wiht Black system by Quarx (extract the .zip in a folder -
open the folder you see fastboot, system and flash, just click on flash)
Sorry for my bad english and i hope this help you

use cis custom rom with fastboot and enter fastboot with Camera+Power and install quarx or recovery and restore from there

Not really downgrading but i will try.
EDIT: Thank you soooooooooo much, i flashed it with the Black system rom and it is working now. My phone was like dead for 1 month and u made it alivee thank u soooooooo much omg.

I'm also having the same problem but no luck yet

You need to factory reset your device if you are downgrading from 2.2/2.3 back to 2.1 etc. Go into fastboot and use the following command
Code:
fastboot -w
fastboot reboot
The boot loop is caused by incompatible data that is on the data + cache partitions. A factory reset will solve most 'android screen' boot loops.

[Solved] Phone is stuck

Hi.
Phone is not bricked, but stuck at a moment of the boot process. Whatever I do, it gets stuck in a loop. It seems that it's a kernel issue. I've tried everything I know to fix this (kdz updater & more than 5 firmwares), unsuccessfully... It happened while flashing with a stock 2.1 firmware from a CM7 M4 ROM.
screenshot:
I think I simply ****ed the phone so it is impossible to solve that now.
Any suggest is welcome.

Fix
IT'S A KERNEL ERROR
READ ALL FIRST!!!
Have the necessary software.
- Phone Drivers
- KDZ_updater
- The Room you want to install (.kdz)
When we light up the phone and leave us this error screen:
1. Pull battery, sim, sdcard out
2. press the power key + the Volume Down key to set the phone into download mode or (Download Mode), and only then plug USB cable... (if its not recognized unplug and plug again)
3. Disable USB LG Driver Model, this will change depending on the operating system we have in the case of windows will be in Manage> Device Manager> Modems> LG USB Drive Model -> Right Click "Disable "
4. Open KDZ_FW select type 3GQCT, Phone Mode: DIAG (if not try with CS_emergency), consider the room to install (File *. kdz).

Hey Veronica.
thanks for you attention, but I already tried every possible things at playing with kdz updater. When KDZU send the IParam 215, the phone reboots, and the error keeps happening, whatever the mode used or the firmware version.
just for saying, there is no need to hold the power buton when the battery is out. Just hold V- before pluging the usb cable.
is there a way to "format" all the datas of the phone ?

first off you do no that the only way you could have went back to 2.1 is with clockwork.
have you tried to see if fastboot works if it does flash a custom rom onto it.

Hey eoghan2t7
I have new events. I've just successfully flashed it with the 2.1 open + fb firmware. Now, it is stuck on the android logo (seems to load but keeps looping).
Fb seems to work (performed a reboot with cmd), What should I do now ?

ok go in to fb and run
fastboot -w then try and boot the phone normally.

thank you very much eoghan2t7
Phone started normally. I didn't know that to downgrade the firm it needs to do it by recovery. However, I rightly tried to flash preciesely by recovery (so wihout knowing), then I got an error and it said something like "update aborted, reboting". The kernel error appeared after that, but before I even try a normal boot. Then I directly flashed using KDZU.
So, it is solved. Thanks again.

glad you got it sorted.

always do a full wipe data/factory reset BEFORE and AFTER flash any rom!

okay Ill' remember it

[Q] Problem re-flashing Swiftdroid

It seems that I'm in a pickle here.
I already had swiftdroid installed but then I wanted to re-install it. So I tried but after flashing euro+fast.kdz , I got stuck in boot-loop. I tried doing the steps but I think I might be doing something wrong. Well, to get into fastboot to test if it went through would be holding the "camera" button or is it "home+camera" button during reboot? Thanks. Been at this all day.
Oh, and it appears every time I try to power on and hold the camera button first, it just goes to a black screen. So, by that have I already installed the rom properly even if it gets stuck on the android logo?
and an update as to what's happening:
going into download mode detects my phone on "device and printers" but as soon as I click on "Launch software update" I lose all the icons and KDZ returns a message saying "Phone was not found" I just noticed this now. What should I do?
I already uninstalled all drivers installed on my pc and re-installed them. After doing so, my phone detected a whole bunch of LG devices. Now on Android logo -- That after doing the Euro+fast and now am trying to do the out.kdz. By the way, even if my phone restarted during the "Launch software update" I waited for it to say finish right before I took out the battery and the usb cable.
After param 207 my phone went into boot stage and my pc re-detected the LG stuff. Now my phone is on the LG logo and it's been like it for a minute+.
I am following several steps on doing this procedure.
--Now question is again.. After this step should I be able to launch fastboot via "holding the camera" button? Do I need to do this while the phone is plugged in to the computer?
......
already tried euro then the out then euro using phone cs_emergency. Currently on Android bootloop. So I think I'm kinda back to step 1. Because initially, when I had swiftdroid, I just did euro using phone diag then afterwards, it went to bootloop. Now when I tried to restart my phone then I press and hold of the camera button, phone goes into a black screen. But looking at the "devices and printers" page, it shows "unspecified--android" on the bottom. What should I do then?
So right now, I'm currently on Android logo bootloop and if I reboot then hold the camera button, it goes to a blank black screen. What should I do next? Thanks
Update:
so yeah, after dwelling on the black screen, I tried to open up Mur4ik's old thread looking for the files I downloaded last year. Tried the command prompt and typed this in
fastboot -w
fastboot flash boot boot.img
fastboot flash system system.img
fastboot reboot
After doing so, phone rebooted okay. Right now, phone status seems fine. Some adventure I had. Will try to work on how to upgrade the version on this unit.

Nice work dude I too did all that stuff, its really adventures
Now I came over it and now I'm trying all roms

[Q] Please help! L7 bricked...

I was flashing a new kernel and then after reboot the phone got stuck at the LG logo. I couldn't and still can't get into recovery-mode. I tried this this and that. But nothing worked.
I can get into emergencymode though, so i tried this page, i have flashed a couple of firmware kdz-files in emergencymode. Some got errors, but the only that changed after that i got to "moving" LG logo (after i hard resetted the phone again after flashing). And when i plug the phone in my laptop i get a battery-icon. Nothing more...
I am at a loss! Can someone help me?

Can you enter emergency mode?
If yes, use lg official b2capp program and flash again everything by your IMEI.

yes, i can get into emergencymode. But the B2Capp program freezes after it tries to find an update... Now trying LG PCsuite...
[edit] LG PC Suite cant find the phone. Now back to kdz-files...

ok, im at a dead end:
- i can get in emergencymode, not in recovery;
- i can install kdz-files from laptop with the phone in emergency-mode, but only the official kdz-files are installed without errors. All other options for installing firmware from a pc fail, i cant get it installed (b2capps) or i can but the program doesn't recognize the form (lg pc suite). Flashing new CWM from laptop failed also.
- even with kdz-files installer android doesn't go past second boot screen (the live one). I got past it once, but i cant repeat the process. i got to CWM then, but when i tried to restore a backup it got in a bootloop. After that all attempts getting past bootscreen have failed.
I got my old phone back, but if somebody has a idea how to revive the LG i'll appreciate it! Right now i'm considering it bricked.

Try To reflash it with LG Software update tool (not PC suite) in emergency mode (voldown and plug in USB) if this won't work i can't help you

Hold the power button until you get a black screen. Download LG Mobile Support tool and the LG Drivers. Plug USB In and then hold the Power + Volume Up key. On your screen, click Upgrade Recovery. From there, you can do a factory reset through download mode of your phone.

In case you did the latest firmware ota upd,there is a topic that can solve you problem as long as you can access TWRP(even if you didnt do the ota it will,i tried that myself) Here is what you need to do.
use TWRP's "terminal command" option to run the following:
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
You'll have to type that whole thing out, and be VERY careful with spaces and punctuation. One wrong letter and you could nuke your phone.
This will probably fix you problem when it has to do with any update.

Thanks for the responses. I finally fixed it.. I started the procedure from scratch with a new laptop and somehow it worked lol

It happened to me and now phone hanged in download mode and can not connect to pc. Did you have a solution?

Solve
Guys! I had the exact same problem today. My solution was to keep pressing the "try again" button every time the error appeared on my computer screen. It took some time but the error was appearing at different levels each time in this order : 45% 57% 65% 80% and next the instalation was completed. If it doesn't work try switching to another computer if you can. After the firmware update hits 100% your phone will restart and the LG logo will appear(the led changes its color during this process). At this point you have to just wait a while. Then a dialog box will appear saying that the applications on your phone are configuring themselves. After that your phone will start and work normaly. The cause of the error is the lack of memory on your phone. If those idiots working for LG would say "YOU DON'T HAVE ENOUGH STORING SPACE" this stuff would not happen.
The phone is not rooted!(IMPORTANT)
Phone name: LG G2
Phone model: D802
Old software: 4.4.2 (KitKat)
Actual software: 5.0.2 (Lollipop)
I hope this hellped you solving the problem.

Hello
I can't access my LG g2 after trying to wipe the system and it runs on frozen screen. Kindly help out please

My LG x power died and I went to plug it in and a screen popped up saying,"Firmwire Update 0%", so I kept it plugged in for the next half an hour, and it still said 0%. I've tried resetting it and powering it off but nothing seems to be working. What do I do?

Download lg flash tool.
Download lg g2 stock firmware.
Press volume up button and insert usb cable. You will see download mode.
Open lg flash tool and flash the kdz( original firmware) through flash tool.select cse flash.

My LG V20 got stuck on the Firmware Update screen. It appears every time I restart the phone and I have to take the battery out. If I start the phone plugged in it starts normally. I was able to do a factory reset, the phone started normally a few times without being plugged in, now it's back to the Firmware screen. I can use the phone but need to restart when it's plugged in. I hope Oreo Update will fix it. I don't know much about updates, but do big updates like that reinstall the drivers as well?

Hello everyone I also have this kind of experience so many times in my g2 mini.stuck on Firmware update. What I’m doing is,
1. remove the battery to turn it off. Plug your charger and before plugging it to your phone hold the volume down and plug in until tou see the android is updating; or
2. Just simply hold the powerbutton + volume down until you see Android is updating.
I would love to see your feedback if it helps.
