Autorec is just the first step to twrp. Go to https://forum.xda-developers.com/lg-g2/development/twrp-twrp-2-8-0-0-kernel-f2fs-tools-t2898705 and get the bumped version 3.1.0-1.
Then put it in your phones memory, boot into twrp you got from autorec and flash the new version.

Hi,
It seems I have the same issue :
I tried to install LineAge, using TWRP 3.2.1 (from CM12.1), but nothing is working (I tried 20180425 and 20180404 nightly versions). After reboot I can see the backlight on the lcd screen but nothing else. Then I tested the installation of a CM12 version, all is right, normal boot. No error message written in the console. i tried also a CM13 install, same as Lineage.
Do you think I have to flask back to LG "OS" ?

Are you clean flashing? Make sure to factory reset, wipe system, data and cache before flash. Never wipe internal storage. Swipe factory reset again after flash. Try flashing gapps later after confirming that Rom boots fine.

Hi,
yes I wiped Dalvik, system, data & cache through TWRP, before flash. But I don't wipe after, I rebooted without GApps...
Maybe, because I read that somewhere, I need to flash a bootstack. I don't know when I have to di it, if I have to do.
Thanks

Yes, you don't wipe after flash, but you swipe the factory reset, it does not wipe but resets the flashed Rom. Give it a clean shot again. Check MD5 of the all files you downloaded with original MD5 to confirm the file didn't get corrupt.
Boot stack flash not needed. Please read the first post thoroughly in lineage thread
"""
Requirements:
Custom recovery (TWRP or any other)
KitKat (KK) bootloader (included in the lg-devs LP bootstack)
KitKat (KK) bootstack minimum; Please read the entire FAQ for important bootstack information. Installation of bootstacks is NOT recommended.
Clean flash if coming from another ROM or CM 13 (no dirty flash, wipe system too check you bootstack(needen bump support)

Hi,
what do you mean by "you swipe the factory reset", I'm not sure what it is, either "give it a clean shot again".
Sorry I'm not very aware of all those processes ^_^, and I'm french so not very aware of some vocabulary words
Thank you

Phone always booting into twrp recovery mode, any solution?

2-3 days ago I successfully rooted my Moto E3 power by unlocking bootloader and installing twrp recovery. Yesterday I installed Lineage 14.1 custom Rom (7.1.2) for Moto E3 power from here
https://forum.xda-developers.com/moto-e3/development/rom-lineage-14-1-moto-e3-power-t3610435
The Rom installation was successful. Phone was working fine. But there was some minor lag and screen was appearing to be yellowish. Hence I decided to Factory reset the phone. I tried to reset it from phone settings. The phone switched off and turned on into twrp recovery mode. Then I tried to factory reset through twrp mode. But it is always booting into twrp recovery. I wiped all cache and data including system data and flashed the above Rom again. But whenever I try to system reboot, it is not booting normally, but always going into twrp mode.
Please provide solution for the issue with appropriate information and links.
Thanks.

Beauause u delete the all ROM
For Reset phone -: not need to wipe system and boot.. Only do a factory reset

Yes, I know that
I had done just factory reset earlier, but after that it kept on booting into recovery mode everytime I reboot the phone. Then I cleared system data to flash the ROM again. I should have done factory reset through recovery mode rather than from phone settings.

Update: Don't know if you still need the solution, but I am gonna share my info. Although as the phone you were talking about must be Moto E3, my phone is Lenovo K3 Note, but the processor should basically be the same, as both runs on Mediatek processors. And for the same reason, they both would use the SP Flash Tool to flash a ROM. You'll need to download the Stock ROM file for your moto E3, and flash it through SP flash tool installed on your computer. You'll get the tutorials on youtube. When the stock ROM is flashed, the phone will start with your stock ROM. I have had my phone do the same and it is fine now.

Yes i recovered from the situation.
You just had to download the sp flash tool and the stock ROM for your respective phone, and flash it . Remember for the above problem you just have to use the "download only" option in your sp flash tool and it will work. if you use "format all+download"
you will left by losing imei number of your phone and then you have to follow other procedure to fix that. but according to me your phone will start by choosing download only.

if u want to use custom rom just follow proper steps and it will install.
-unlock bootloader (which i assume u already have)
-fastboot boot latest twrp
-do a full wipe and reboot to bootloader.
-again fastboot boot the latest twrp
-now copy rom,gapps,magisk(mandatory) and twrp installer(optional)
-install rom and twrp installer only
-reboot to booatloader and fastboot boot twrp again or if u installed twrp installer just reboot to recovery.
-now flash magisk and gapps
-reboot system
By mistake if u flashed factory.bat then read this : https://forum.xda-developers.com/mi-a1/how-to/guide-how-to-restore-imei-permanently-t3759190
if your phone is rebooting after every 60 sec then u most probably corrupted /persist. Don't worry custom roms will work without any problem as they don't touch persist.
did you by chance used flash_factory.bat in mi flash tool ?

and i did use flash_all_lock_crc.bat in mi flash tool then i'm start getting the restart problem with unread sim card

use flash_all_lock.bat only or flash all except storage.bat or flash_all.bat .except these nothing else.
flash custom rom or flash_all_lock.bat in mi flash tool (it will work work most probably).

I used partition dl mode to flash the stock oreo rom over 7.0 to keep the root. Then i flashed custom kernal for stock 8.0 but it didnt work. I have done the same procedure before and it has worked like a charm. But it keeps on giving the encrytion error when i try it now

Odd. If I had to guess anything, it would be that not all the partitions were flashed when going from Nougat to Oreo.
I once flash a Nougat ROM from an Oreo ROM and I had the same encryption issue and lost everything.
That was the last time I would trust myself again and not do a backup.

Flash stock recovery from KDZ through patched LGUP & do a factory reset .
After stock recovery completes the wipe do a battery pull, flash TWRP via fastboot, format data, flash Kernel & Magisk & you should be back on track...

I tried that as well. With stock recovery is says data is corrupted and doesn't do anything. I think it might be a problem with patched lg up because when i use normal lg up to flash oreo it works. But I cant root then.

I would try changing to 3.2.3-4 TWRP and then trying the procedure again. It seems that the 3.3.0 TWRP does not decrypt properly sometimes.

In the same boat as OP

Hi
Looking for a way to keep TWRP and root ... any help appreciated
I've got a US996 with the same issue as the op. I have the latest TWRP 3.3.1-0. The phone was working fine until I upgraded twrp but I might have done a mistake resetting phone outside of twrp.
I can still get back into twrp but I haven't been able to install zip files without getting that decryption unsuccessful message when booting to system.
When getting back into TWRP using hardware buttons sometimes there is a prompt asking "keep system read only?" which I never chose and swipe to allow modification. I think this happens after
I pull the battery after getting the decryption unsuccessful message. There is a reset system that I could chose under the decryption unsuccessful message but I'm assuming that will make me lose twrp
...but if my phone is a us996 and is still
unlocked, would it matter if I did select it? Wouldn't I be able to reinstall twrp using adb again on a computer after Oreo is reinstalled?
To do Prowler_gr's suggestion which guide do I follow (sounds like I should do the second option)
"Flash stock recovery from KDZ through patched LGUP & do a factory reset .
After stock recovery completes the wipe do a battery pull, flash TWRP via fastboot, format data, flash Kernel & Magisk & you should be back on track... "

Don't blame me if this goes wrong but I'm pretty much 100% certain that you mush press the rest button. This has happened to me a few times I'm sure. You won't loose twrp. Whatever resetting goes on in the background I don't think it's an actual Factory Reset.
Edit: Just to be clear you taking about a white screen with I think in dark blue or black text ENCRYPTION UNSUCCESSFUL and something like "reset phone" option directly under it, on the upper half of the screen?

Hi ezzony
Yes you are thinking of the right decryption unsuccessful page. I get it when booting to system
after installing Oreo and magisk 19 and having wiped everything (format data too). I will get the exact wording of it tonight
Thanks!
