LG H918 Bootloop Download mode not staying on - LG V20 Questions & Answers

Hello Everyone. I have a problem and unable to find a solution. I am new to LG and I was using an app and realized that the sound suddenly stopped working. I checked and was getting sound outside of the app. I decided to restart the phone thinking it was a glitch, I used the restart option via the power button and upon restart it went into bootloop. I can get into recovery and I hard reset the phone but it remained the same. I can get into download mode but it only stays in the mode for approximately 5 secs then goes into bootloop again. I can get into fastboot and it will stay in that mode. the bootloader is locked and I believe I am on Naugat.
I do not know what else to do, please help!

Nope.
You need download mode open for that.

Then it depends. If unlocked version you are correct, on the T-Mobile version, H918 , that will not work.
Also for models with eng boot, I don't think that's how it works. Though I could be wrong since I own the H918 and don't follow the other models.

hmm... there are kdz files available for tmo version, right?...
---------- Post added at 02:49 AM ---------- Previous post was at 02:46 AM ----------
all partitions are flashable throuh fastboot... so if he can get a kdz, unkdz it, then grab the laf partition, then he can reflash laf using "fastboot flash laf laf.img"

I appreciate and understand that you are trying to help.
But seems like you don't have much experience with the tmobile version of V20 (tmo version is quite different from the other ones), so why comment and mislead other people!
(I am sorry if I seem rude, but that is not my intention.)

@runningnak3d
Maybe you can shed some light on this for the OP?

Yes please... I am learning so much already and really need this phone up if possible!

Not rooted + bootloop = hardware failure ...
Send it to LG and tell them you want it fixed as per the class action lawsuit settlement.
-- Brian

Ok. Out of frustration I left the phone plugged into the computer in fastboot mode. I went away for 2 hrs and return to find the phone booted in normal mode and working flawlessly.
I have not idea what happened, could it be a power management ic like the g4 or a battery problem? I immediately turn on oem unlock and usb debugging just in case the phone has a software problem and I need to flash in fastboot.
I strongly believe that this could be a hardware problem though. I sent this msg from the same V20. I am just happy it is working.
I would like to thank everyone for their help, I appreciate it.

It may be a faulty MB

Hi,
I have a similar problem. I used the lafsploit method and rooted my h918, installed h91820h. I then updated TWRP using the twrp app to the latest twrp. Then I went and updated Magisk to v21 and let in reboot. It is now stuck in a bootloop. I cannot boot into download mode, recovery mode, or the system. I can only boot into fastboot mode. I can't boot into a twrp image using fastboot because a command is missing. Is there a way to bring my phone back from the dead?
Thanks,
Rob

[Solved] Tmobile LG G2 Stuck at TWRP

I am stuck at TWRP boot loop. None of the data shows, or anything, says cant mount data sometimes. isn't recognized on my PC by ADB, in Device manager it just shows Other Devices, LG G2 with a yellow exclamation. I have the drivers installed. I tried the fix that is provided on here that you do by accessing the TWRP Terminal Command Line, and typing in the command given in the post, but that doesn't do anything. Says something about device is full and that 32GB were written. I am at a loss here, need help right away.

How did you get this problem? Then a answer will be easier....like sideload a ROM, and using koush universal drivers.....
So...I sold my phone and the guy accepted the OTA and got stuck in recovery boot loop. He lost my number so he took it to the local phone repair/ripoff guys. They used twrp to delete everything on the phone. No system or internal. I used adb to sideload clean rom. It installed but I'm still stuck in twrp boot loop. My pc wouldn't recognize my lg either. Device manager have no the same problems. Luckily some research lead me to adb via pdanet drivers. I'm thinking he's in the shoes.

Great! Sorry man was eating....the devs did it again!
I just ended up flashing stock images to the phone then re-rooting and flashing twrp.
Sorry I didn't have more detail as to how it happened. It was a friends phone. I initially did the root and custom recovery for him but then he accepted some update which I am assuming was an OTA.
Also said he tried flashing a Neo Geo ROM via twrp haha. So I was completely lost on where the problem started.
Thankfully its fixed now and I learned something new today. How to flash a factory image to a LG G2 lol

You can also use adb sideload to flash the ROM. Install kouch universal adb drivers and download minimal adb and fastboot both can be downloaded from a Google search. Then on your phone go to twrp advanced and adb sideload. Then put the ROM.zip folder in the minimal adb and fastboot folder. Then hold shift right click and press run command line here. Type "adb devices" if it finds your device then use this command "adb sideload *ROMNAME.ZIP*. Replace * and ROM name with the proper name of your zip file.

How to root Honor 8 Lite PRA-LA1 Android 7.0

Hi
After successfully unlock bootloader i am not able to root Honor 8 Lite PRA-LA1 Android 7.0 with xposed tools because in recovery mod there is no option for install zip files.
How i can root .?
I wonder the same
I tried "adb reboot bootloader", but when tried "fastboot oem unlock", I got "failed, password wrong".
I unlocked bootloader http://emui.huawei.com/en/plugin/hwdownload/download and Open road to root....
However is not sense, because will deleted all you stock apps (include keyboard), include Google app and Google Play. For this model NOT PRESENT AND probably WILL NO any stock firmware or recovery! Will every boot "Unlocked and not thrusted", and if try flash this recovery (https://twrp.me/devices/huaweihonor8.html), you got soft-brick (will available bootloader).
If you tried, probably you have no any chance....
Type "fastboot oem relock" with gotten early password, but you anyways will have no Google Play and keyboard.... For full worked firmware you anyways have no chances.
And... RIP finally, not possible even to bootloader.
I waiting when battery fully lost of charge.... Probably will chance to enter to bootloader.
I partially restored firmware...
can anybody give me huawei honor pra-la1 firmware its stuck on logo just go fastboot mode but bootloader locked there any sulation??????
