Lg G5 Boot loop HELP - T-Mobile LG G5 Questions & Answers

So yes I can't remember if I had unlocked it or not. Right now I am stuck in bootloop with red small txt i can't even read. Guessing its boot failure. I tried doing what ppl have said by downloading a full tot but LGup keeps telling me anti rollback ver is smaller than the device version. I am stuck and need help plz.

Im in the same boat as you bro
Any luck?

Same thing happened to me.
You have to unlock the bootloader before flashing the tot file.
I rolled back to orig firmware using kdz file from lg, unlocked bootloader then followed rooting instructions.
All rooted now.

I'm not sure what version I had to unlock boot loader. I do remember rooting was the hardest problem to get started. Kingroot was the only way I could root but its a pain in the ass and I didn't like it but I was only temp till I unlocked and flashed CM. I couldn't find one that worked but kingroot.

Hi, you can root your device easily but you'll have to unlock bootloader first... maybe you have to ask motorola to do that.. and install MotoRoot or PwnMyMoto and hit setup and you are good to go :fingers-crossed:

Are you able to access recovery? if you have flashed the firmware and still stuck at boot animation or motorola logo then try wiping cache and perform a factory reset
Hit the thanks button if it worked
My device is not eligible for unlocking bootloader
Try to manually flash via fastboot

I think you had a higher version of the firmware, you can download the latest compilation (su6-7.7) but I think it couldn't be rooted because I tried with the method you posted and I couldn't root the phone so I just reflashed it manually via fastboot with the latest firmware available

Rooting 10D with tot issues

Has anyone successfully rooted 10d with the tot method? My phone always fails to boot. I get a red boot method saying boot verification failed. I've followed the instructions exactly on the guide posted in the dev section. If anyone has any ideas, let me know. Thanks.
You might of forgotten to unlock boot loader first? Or forgot to check off USB Debugging? I had a similar problem. I solved it by using LGUP to flash stock tot. Then I retraced my steps and start all over again. Step by step.
Yes u need to fastboot oem unlock
Your bootloader before hand or it will fail
Sent from AOSP Developer Cfox88
I'm having the same issue. I was able to flash the kdz after a lot of headache and reinstalls. That reset my phone as it was supposed to. I then unlocked my bootloader again and tried flashing the tot but no, it fails every time. My computer just broke down too so I'm completely stuck in limbo now.
Sent from my LG-H830 using XDA-Developers mobile app
I could be mistaken, but I think once you upgrade to 10D without following @autoprime instructions you're stuck.

Hey bro,
You don't need any DLL file.
To flash it you simply have to use same LGUP version used for LG G5 and follow same steps like you flash for KDZ files.
Just tried and it works perfectly
Also, LGUP can take dz file for upgrade (data stays intact).
is it possible to insert SuperSu directly into the restore file to have a pre rooted stock rom, while we wait for TWRP??

That's what @tungkick did.
He made prerooted .tot for G5 and .dz for G Pad X 8.0
Both are T-Mobile version with unlocked bootloader with missing fastboot commands.

Actually, locked bootloader does not matter anymore.
You have to do reverse engineering with hex editor to retrieve keys in order to bypass the bootloader. This is how Samsung Tab A6 can be rooted and TWRP installed even the bootloader is tight locked (and you have to patch the kernel to change SE Linux policy).

It would be great to bring all our computers together to crack the code like mining bit coins. How neat would that be.
Are you guys optimistic for root on the V20? Or will it be a similar story to that of the Note 7 with 99.9% stable root?
Thanks for your efforts.

Problem after flashing firmware and skipping Supersu

So recently I wanted to flash 20a via twrp on my G5 but it wasn't working. I reflashed 10i and my phone didn't want to boot up. So I decided to charge my phone after reflashing 10i once again without flashing supersu and I powered off the device and it turned back on with the "Your device is corrupt and it cannot be trusted sign" and so I tried to boot to recovery and my phone just factory reseted itself. I tried to boot into recovery with adb but to no avail. I even tried to flash 10d kdz and 10d tot both getting an error on LGUP and my phone is still stuck on firmware 10i. I even get an error when trying to update it with stock recovery. So now I have a phone with an unlocked boot loader and I cannot reroot again. Is there a way I can regain root? I knew I should have flashed supersu

I bet you didn't followed or read the 20a thread by autoprime nor did you bothered to read the TWRP thread as well. there's still a bug that prohibits you to downgrade from 20a unless you have a nandroid backup or a twrp recovery backup for the 10i. best option for now is to go back to 20a and wait for an update from the devs on fixing TWRP or try to follow the dirtycow method.

Look under the dev thread on autoprime topic about the stock N zips, if you read through last few pages you'll find all the links you need for recowvery to get root and twrp. Also if you're on 10i, why not just use lg up (make sure you either use older version or autoprime uppercut app) to flash 10D tot that already has twrp and then upgrade to stock 7 through twrp. Either way, all the info you need should be in last 3 pages of that thread by autoprime.
*** Edit ***
Just reread your post. If your getting errors flashing the 10D tot it's most likely due to you updating lg up, the .DLL, etc to install N. If so, uninstall lg up, and then download the lg up files and. DLL from the 10D thread. You can try uppercut app too as it's supposed to work between versions but I have not tested it myself. If all else fails then use the recowvery method.

Yeah not sure about uppercut. If you're still on 10i you should be fine using lgup to downgrade as long as you use the right version of lgup and h830 .DLL file. Also I'm not sure you can use refurbish option with kdz, but I know you can with tot. So maybe downgrade to 10D using tot and upgrade through twrp. If all else fails, use the recowvery steps on the above linked thread and you should be all good. Quick question, when you first start your phone, does it just show phone can not be checked for corruption or does it show the message can't be checked for corruption and visit this site... Etc. ? Reason I ask is the second message is updated bootloader and you won't be able to use lg up to flash MM firmware until you downgrade your bootloader.

Updated bootloader? I had no idea that was a problem. But since I'm on 20a i get the corruption message plus the link so O guess my bootloader is upgraded. How exactly DO you downgrade the bootloader?
I will mention that I'm stuck without twrp

Okay since you have an upgraded bootloader and no twrp you will have to follow the steps in that post for recowvery which will give you Root and twrp. Once you have twrp, download the bootloader zip for whichever version you're planning on downgrading to (I.e. 10I bootloader if flashing 10i kdz) from autoprime and flash in twrp. You can also flash the complete zip (i.e. 10I complete zip) in twrp after flashing the 10I bootloader if you want to keep root and twrp (you will also have to flash SuperSU after flashing those files). But you can also flash kdz or tot with lg up after downgrading bootloader via twrp but you will lose root and twrp unless you flash 10D rooted tot.

I don't think so but not 100% sure. If you follow the steps carefully you'll be fine. I didn't directly post the recowvery steps as I have not used this (I've had twrp and root since 10D). You can look on the v20 thread as it has a post for the v20 and our h830 recowvery method. Sorry I can't be more help with that specifically.

Can I use LGUp...?
Good day,
First, let me say THANKS for an amazing effort! I've been successful in rooting by installing the H91810j image and performing the dirtycow exploit.
Now, I'm wondering if I can update to H91810k, and still preserve root access, by using LGUp to install the modified 10k image you posted...?
Let me know... Thanks!
Ok I got a V20 today and it came out if the box with 10K is it possible to root possibly through downgrading in lgup or am I going to have to not update and wait for a root for 10k I'm on T-Mobile variant

As far as I've been able to find out (since I was in the same boat), 10k has not been successfully 'rooted' as yet. You'll need to load H91810j and use the dirtycow exploits to enable root.
Once that's done, THEN you can install the modified version of H91810k mentioned earlier in this thread. Be sure it's the modded version, if you expect to keep root access.

Think I need a kdz?..Just got replacement with H91810K that I want to unlock and root.. realize I need to downgrade, but just looking for a thread on downgrading I think.. All help sincerely appreciated. Thanks in advance

I believe all you need to do is boot into fastboot thru ADB and type fastboot oem lock. I may be wrong on the typing part. But that's the general idea. Find out what command unlocks and just do the opposite and type lock instead.

you'll need to downgrade to 10j with the KDZ, root, install TWRP, then flash the zip here https://forum.xda-developers.com/v20/how-to/h918-twrp-flashable-stock-firmwares-t3619671 to bring yourself to 10k while still retaining root
