HELP!! Lg optimus l5 keeps rebooting after unlocking bootloader and installing CWM

my lg optimus l5 E612 keeps rebooting itself after the media scan. this didn't happen untill i unlocked the bootloader and installed CWM. i have tried to wipe the cache, the dalvik cache and a factory reset in CWM but still kept rebooting. So I restored the original bootloader and recovery than done a factory reset and that stopped it. I downloaded the the ulocked bootloader from a diffident website and tried doing it again but still did it. how can i fix it??

The solution !!!!!!!!!!
Enable USB debug (before your phone reboots).......... very fast!
first
you must have patched you phone with recovery (mmcblk0p17) and boot (mmcblk0p5) partition
This file is extracted from the russian firmware....... is the bootloader!!!
I try this process with my phone (lg e612f)...... and no more reboots
copy the file to the sdcard
docs.google.com/file/d/0B-im6Vo1WjAEV1phbWRLOXIzX00/edit?usp=sharing
run from ADB
adb shell
su
dd if=/sdcard/immcblk0p9 of=/dev/block/mmcblk0p9
reboot recovery
enjoy...... your phone is unlocked!!!!!!!

willthis work with mine because mine is not the f model

HELP!
I would try this method above but the LINK IS BROKEN...
Thanks in advance

Hello,
I have exactly the same problem with my Optimus L5 after unlocking the bootloader. Any idea where this problem comes from and how to solve it?

Did you use the exact bootloader for your model?
See this post

Thanks for the answer,
I used this OL5_1.0

Also according to Android my phone is E610, but on the back it's written E610/E612F, so which one should I try?
Last problem, since I have installed Cyanogenmod there is no more "charge only", I don't know if it's really important though. I will try to have yours work.

In android the model can be changed by modifiying one line of build.prop, so i'll trust what the back of the phone says...
To me, while connecting usb is the same on pc... nevermind the "charge only"

I was about to commit suicide because I couldn't get adb working. But finally I managed to enter those 3 commands in the integrated Terminal Emulator, having previously installed the file for E610:
Code:
su
dd if=/sdcard/emmc_appsboot.bin of=/dev/block/mmcblk0p5
reboot
And it worked. That was quite hard because I only had 2 minutes between the boot and the reboot. Thanks for helping me. :good:

[Q] TMobile D801 Stuck in TWRP boot

Needing expert help. I have a rooted LG G2 D801 with a custom ROM installed. Was stupid enough to accept the most recent OTA and now it just continually goes into TWRP. Have tried to reinstall custom ROM from TWRP. Have tried the LG software to install the kdz file. Always gets stuck at step after extracting the kdz file. Even took it to a local guy and he got stuck in the same place.
I just want the phone back in working order. Don't care which ROM. Will pay $20 for anyone with the working answer.
Thx.

you can do a couple things. Sideload a new rom from your computer. Google how to setup the drivers and do it. OR from what Ive read you can delete the system partition like you are gonna flash a new rom then you wont get stuck when using the kdz to go back to stock.
Also look on the forums, I think you can run a command via shell in twrp to delete the fota dir and it should boot to. Dont quote me on that

I found this other solution in the noob friendly help thread which helped recover from my specific situation with less hassle:

At first, the terminal seemed to show an error after the operation ("not enough space"), but it did fix it none the less and the phone rebooted normally again.

If you get into a recovery boot loop (where the phone keeps booting into the recovery, and not the OS), 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

This should boot up your phone without any changes.

did you tried to restore everything to stock with a kdz file? you can find it on google and you can flash it putting the device in download mode and using lgUP / uppercut to do so.. if you need help you can send me a PM

Is there any better solution for this problem?
I solved it once with a full reinstall an this uppercut tool.
On reddit for other phones there is the solution to boot to bootloader and do
Code:
fastboot continue
resuming boot...
FAILED (remote: unknown command)
finished. total time: 0.001s
But this does not work.
It seems my phone boots to twrp because the lineage os updater app set s.th. to automatically boot to twrp. How can we remove this auto-boot to twrp flag?

Sorry for bringing up this again. I did an OTA update on lineageos on my lg g6. The phone booted correctly in twrp, I installed the update but now the phone boots directly to twrp without any way to let it boot the os. How did you resolve this?
Thanks

Only solution back to stock & after install LOS and wait until bug is fixed.

I use a lg g pad x 8.0 and ran into the same issue.
fastboot continue would not work.
the dd commands did not work either
I think the "msm_sdcc.1" is device specific.
In recovery, I used the file manager to look in /dev/block/platform and notice that "msm_sdcc.1" did not exist but there was one folder in there. I went in there and there was another and kept going til I found the "by-name" folder
then I ran the dd command replacing "msm_sdcc.1" with what was on my device.
I did it for "fota" and "misc" and then my device booted

Someone else has had this problem @gnackwatschn, you can find a way to fix the boot loop here https://forum.xda-developers.com/lg-g6/help/twrp-bootloop-lineageos-ota-update-t3746014/post75488796#post75488796

WARNING! I ran into the same problem on the LG G6 with the nightly update dated Nov 1, 2018. Did what you did, but wrote down the command.
After navigating to the TWRP > Advanced > Terminal, first do
Code:
ls /dev/block/platform
Mine had one entrie: soc, which had two entries: 624000.ufshc and 74a4900.sdhci
only 624000.ufshc had a by-name directory containing fota and misc, so my commands ended up being:
Code:
dd if=/dev/zero of=/dev/block/platform/soc/624000.ufshc/by-name/fota
dd if=/dev/zero of=/dev/block/platform/soc/624000.ufshc/by-name/misc
The commands run, saying:
Code:
dd: writing '/dev/block/platform/soc/624000.ufshc/by-name/fota': No space left on device
8193+0 records in
8193+0 records out
4194304 bytes (4.0MB) copied), 2.783000 seconds, 11.5MBs
and similar for misc.
Reboot to system gives a warning, Your device has failed a routine safety check and will not boot.
Now I'm stuck.... guess its time to start another thread.

Always booting to TWRP

I've installed TWRP last weekend and installed LineageOS 14.1 for my LG G6 H870.
I was tinkering with Magisk and Magisk Manager to be able to use Netflix, I didn't restart my device after this step.
Last night LineageOS offered an OTA update and afterwards it restarted to recovery mode.
I assumed I had to install the new image manually so that's what I did.
After the installation the phone rebooted back to TWRP Recovery so I wiped cache, data and dalvik.
It still rebooted back to TWRP recovery so I tried to reinstall LineageOS again by following these steps: https://wiki.lineageos.org/devices/h870/install#installing-lineageos-from-recovery
The phone still only boots to recovery so my assumption, after some reading on XDA, is that something is wrong with the bootloader.
This could have happened when I was tinkering with Magisk, I think I've seen a notice that I tried to make changes to the bootloader.
To fix the bootloader the main suggestion is to flash the stock rom so i've started that path.
I've installed Uppercut and LG Up use links from this thread: https://forum.xda-developers.com/lg-g5/development/uppercut-lgup-loader-g5-variants-t3511295/
I found a stock rom at https://lg-firmwares.com/lg-h870-firmwares/#firmwaresList and I assume I need the "NEU/NORTHERN EUROPE" rom.
When I open Uppercut it says "There is no handset connected".
I've got no clue what steps to take at this point.
FYI I'm able to get in to the bootloader mode and the recovery mode but havent been able to get into the download mode.

If you still have twrp just flash stock from there.

I didn't know it was possible to flash a kdz file using twrp.
According to this reply it isn't possible using kdz files https://forum.xda-developers.com/showthread.php?t=2650569
Do you know for sure that this is possible?
I think I need to flash the bootloader using fastboot but I don't know what source to use, and I hardly found bootloader files on the web.

I don't think Magisk is modifying the bootloader, but I could be wrong.
You can find the H870_v10T and US997_v14A bootloaders here:

Thanks for pointing out that thread!
I downloaded the bootloader and succesfully installed it using `adb sideload LG-H87010f-Flashable.Bootloader.zip`
But the phone still only boots to TWRP.
So I tried to flash a complete stock rom from https://forum.xda-developers.com/lg-g6/development/rom-eu-lg-h870-10t-rom-t3654134
I did wipe Dalvik/ART, Cache, System and Data and afterwards installed that rom.
Unfortunately these steps didn't make any difference to the boot sequence.
I've been trying again to get into the download mode using key combo's and using `adb reboot download` but it reboots to TWRP instead.
What should I try now?

I finally managed to enter download mode!
In the end I figured that I confused the key combo from my previous phone with this one.
I should only hold the volume up button and then plugin in the usb cable.
What I tried numerous times was a combo of volume up and power button.

for reference and people showing up here later. Doing lineage OTA updates on the G6 forces the device into that endless boot loop into recovery. You get out there by entering the shell in TWRP and dd'ing some zeros somewhere. I had it once but sadly did not write down how I solved it. Google for boot loop and twrp you will find hits here on xda where you see a dd if=/dev/zero line and explaining what todo. It is a bit different for each device, but the article tells you what to look for. As I understood it, writing some zeros at the start of a partition ends the loop, but I am no expert there, it just worked for me.
Oh yes, and stay away from lineage OTAs
Edit: ok, not xda but reddit, anyway here is the link
https://www.reddit.com/r/LineageOS/comments/5riech/how_fix_twrp_recovery_boot_loop_after_lineageos/
The life saving post is a comment further down by muniak
I'm using TWRP 3.1 and still had this issue.
Despite thinking my phone was rooted, I couldn't su, adb as root or anything, so I couldn't /fstab. I ended up looking around and comparing the path I was in with other's. So if you're having this problem just keep going around typing ls and pressing tab like below. Basically you're looking for "by-name/misc" in "/dev/block/platform/".
ls /dev/block ls /dev/block/platform ls /dev/block/platform/[dir or two] ls /dev/block/platform/[dir or two]/by-name ls /dev/block/platform/[dir or two]/by-name/misc
Then the dd if=/dev/zero of=/dev/block/platform/[dir or two]/by-name/misc count=1 bs=32
Good luck and thanks so much for the help!

Same happend to me, there are some post that say you have to boot to bootloader and send bootloader continue command with your PC, however that didn't work for me. To flash with LG UP you have to have your phone off, connect USB cable to PC, press Vol+ on phone and connect the USB cable to the phone, it should start in a mode called download mode, then LG UP should find your device
