[L7]stuck at lg logo - Optimus L3, L5, L7 Q&A, Help & Troubleshooting

hi guys
im not new to flashing but this is the only problem that makes me very nervous
im on v20e by szymel i have cwm 6.0.3.2 and when i tried to install the slimbean i got status 7 error so just rebooted the device to install rom manager to update my cwm recovery but i cant download it just stays at 0% so i cancelled it and downloaded the official recovery image from clockworkmod web site and i installed it thru terminal emulator using this command
su
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p17
i thought it was success becoz i tried to reboot to recovery it boots to recovery but when i saw the version its not updated, then i recall i missed a sumthing on the command, the command should be like this
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p17 bs=4096
now my phone is stuck at lg logo cant boot to recovery, didnt try to boot into emergency mode though
ill report if i can boot to emergency mode and flash a kdz

Use the KDZ to get back to square one.
Seems to be the best solution to your problem.

Good to know i wasn't the only one
Im just able to start researching now, i'll update if i find anything, but i assume there's some kind of command that can be given via adb to disable the fastboot and allow the phone os to resume functioning, as my logic indicates since the restore worked for you, your phone is now simply at a point with no attempted update. i did the same process of clicking reboot, twrp looping, restored a backup and twrp still looping
EDIT: Pretty sure it's going to be a flag in a flat file. Combing over my init.rc file now, and i found a strange file called smpl_boot with a single 0 in it, not sure what it does

Can you enter Download Mode? (Holding volume down when G2 is turned off and plug the USB)
I also experienced this when restore using TWRP. But fortunately I can flash back to stock.

450 Fastboot mode started
500 udc_started()
Now i cant do nothing with phone, i try to power off and turn on it just go to

ahh i misread your post thinking you somehow had status messages on your screen during boot and that you got into TWRP each time. the question above this post asking about download mode may help you

fixed it for me for anyone finding this post that CAN get to TWRP, the above linked post has other hints as well that may work for OP
I got this same thing when I tried to update TWRP using flashify, I can reboot to phone , running CleanRom 2.0 but not to recovery in order to flash other stuff.

My situation is a little different than yours, but you may be able to do this method (which is what I am working on at the moment). As long as you can get into download mode.

Hi, sorry for my english , I'm french
I wanted to flash a custom rom on my LG G2 D802 .
I wanted the Paranoid Android (PA +) with 4.3 JellyBean .
So I made the
Backup
Wipe data / factory reset
Wipe cache partition
Wipe dalvik Cache
After I
Choose zip ( custom ROM ) from sd card
Then I
Reboot System Now
And turn on my laptop, I get an error message saying
[640 ] started Fastboot Mode
[ 690] udc start ()
I realized I had to flash AOSP kernel before changing to a ROM paranoid . But my kernel is blocked and so I have to go back to the stock ROM
When I did this tutorial using lg tools , flashing stops at 49% with an error message .
I also saw that I could access the recovery mod by following this link http://forum.xda-developers.com/show....php?t=2565904(but I saw that I could not otherwise reboot my phone after it was bricking ) and therefore flash my stock Rom which I had made the backup . But I do not know if the ROM has been saved and if it remained in my files after the Wipes.
If it is not there, is that in buying a micro USB ====> HUSB adapter, I could install a stock ROM from a USB key ? Or is there a way I can put files from my computer to my laptop which has no port micro sd?
And is what I could with my kernel "blocked " ?
Thank you very much
Same problem here too. Can't get a recovery installed no matter what i do
Does anyone have a solution yet?? Same thing has happened to me.
If you can't go into download mode but get fastboot mode instead first repair download mode using http://forum.xda-developers.com/showthread.php?t=2477595 and than flash back to stock 4.2.2 using http://forum.xda-developers.com/showthread.php?t=2432476
My G2 can not go into download mode and recover mode, and my computer can not recognise it so I can not put anything to it.
fast boot
udc error.
CAN SOMEBODY
EXPLAIN IN SIMPLE WAY STEP BY STEP.
Thank you
Had this exact error too, fortunately flashing furnace kernel fixed it.
Tahir, I had to try several times until i succeed to boot to my recovery mode, try several times.
was having this issue. but i figured out my problem. the rom i was installing was a note3 rom. hahahaha. thats what happens when u have too many phones. and files in your computer. anyways.
i ddnt have to revert back to stock. i was able to reboot to twrp via hold power button and volume down buttons, when lg pops up, let go and press and hold both buttons again. when white screen with words comes up, press power then power then power. then ur back to twrp, at least mine did. and restored my recent back up.

How did you flash the kernel if you couldn't get into recovery?
I have download mode, but lg support tool only goes to 49% and I get error.
Would like to flash this kernel if you have another way

Try booting to recovery after you charge your phone for at least one hour and while it's NOT CONNECTED to the computer
If that's doesn't help try using ADB

"If you DONT have ADB access (because of an early build of TWRP), you can simply use TWRP's awesome "terminal command" option to run the following:"
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
That got me back to a working rooted 4.2.2. After that, download mode and everything else will work.

No Download Mode,Stuck in TWRP....Please Help!

Hey,
in the last days I experimented with many Roms and Kernels.When I installed a Lollipop Rom I got a mounting Fail in TWRP,i didnt think bad and got back to Cloudy G3.So today i wanted to flash Cm11,but i recognized that my USB-Stick isnt recognized as normally,but i were able to install Cm11 from my the USB-Stick..So I get into TWRP and flashed Cm11.But after installing Cm11 it didnt start,i get after Lg-Logo into TWRP.So i flashed Cloudy 2.6,the same ****.Then i tryed to get back to stock,with download mode,but my download mode is away,when i want to boot into download mode,i get the download mode picture for some second and get into the Fastboot then.My Pc recognizes the phone.
After that i tried to do that:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
My Phone is a Vs980
After that,nothing has changed....
Please Help me,i wanted to brick my second mainboard again.....Sorry for my bad english.
Do you have any backup? If you can access rec just wipe everything except internal storage and it should work
The Problem was,that my USB-Cable was broken,so TWRP cant mount it and so the rom couldnt be installed,i use ADB to get the Rom on my Phone,everything worked...

d801 boots to cm13 but no recovery and no download mode.

I flashed to cm13 nightly 20160302 and my phone boots to cm with no problem but now I am unable to boot into recovery through any method with twrp 3.0.0.4 or any twrp version I tried inside of twrp manager or flashify, I am put into fastboot mode when trying to enter recovery with 3.0.0.4 and a few other I tried while other versions give me unsecured boot message. When trying to go into download mode I get the first download mode screen and then the screen goes blank and brings up 15 system partitions on my pc with only one partition containing a folder called image with a bunch of files. The phone is detectable through adb and as a storage device on my pc while booted into cm and while in fastboot mode the phone shows up as marshal london device- marshal london bootloader interface in device manager with no storage.
I planned on going to cloudyg2 but now I'm thinking about just going back to stock, would I be able to use the lg flash tool to get back to stock? Or possibly use adb recover to stock or use adb sideload to flash the default lg rom?

System Partition not booting, after reboot its booting into recovery!

Hey, sorry for the ignorance!
I flashed this ZUI (Nougat) rom on top of CM 13 data, phone did boot with old apps. When i pressed factory reset from settings menu the phone went to recovery and since then its only booting into recovery and not into system! everytime i get into TWRP system is not checked. even after mounting system and flashing stock zip. The phone isn't booting into system but recovery only. Tried flashing system.img by Fastboot.
Solved by using QFIl
Flash stock recovery, then boot into recovery.
It will automatically do factory reset, after that your system partition will boot.
Then flash TWRP again.
And do remember, not use Factory reset option from OS while on custom recovery.
Had the same issue, went to fastboot and then flashed through adb. Worked as a charm.

How to switch off the phone stuck in zUK logo with no recovery installed. I tried long pressing the home button but it reboots to zuk logo ,is there any way to switch off the phone
This will fix it without losing any data. (NO FACTORY RESET NEEDED)
Go to TWRP recovery terminal commands, and enter the following:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
PRESS ENTER
THEN TYPE
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
THEN PRESS ENTER
REBOOT
This should boot up your phone without any changes.
