TWRP installed, but unable to boot into rom - G2 Q&A, Help & Troubleshooting

Hello,
I've installed twrp on my lg g2 802. Using twrp i tried to install lineageos, but on reboot the screen remains black. I see the monitor on but nothing happens. I have to force the reboot. I can still go into recovery but i don't understand where is the problem.
I already tried to wipe everything, and i installed latest nightly of lineageos (no gapps).
Da you have an idea?

I have this same exact problem. I hope a solution is out there!

i installed from a kitkat. Maybe this can be a problem? Should i install lineage from a lollipop?

I got LineageOS to work!
It was a long grind of reading various posts on here and looking up other info on google, but I finally got my phone to run LineageOS.
The three things that I think are key are:
Making sure your phone is starting off with kitkat. I wasn't able to root my phone with lollipop. Stumproot, towelroot, and ioroot all didn't work. Once I downgraded to kitkat, I rooted successfully with ioroot.
After getting TWRP, updating it to 3.1.0. I had to first get an older version and then flash 3.1.0
Change the bootloader to kitkat if it isn't on it already. I used Bootloader Changer.

Yes u need lp bootstacks. Or you can simply get to the stock lollipop using flashtool and then flash lineage os

Thank you for support. Now it works

[Q] No Recovery after CM upgrade

Hello,
hopefully someone could help me solve my issue.
i've installed the latest nightly of cm 12.1 today overwriting my previous installation of cm11 with a build from january.
the recovery i used so far was twrp.
after upgrading cm to 12.1 i can no longer access the recovery. the phone shows a black screen and reboots when i press the power button.
i've tried reflashing current and older (2.7) versions of twrp with odin but with no success.

You should have flashed official lollipop first, to get the latest bootloader. And you should begin there. And then flash twrp for your rom and cm12.1 using twrp.
Use a cm12.1 rom from development forums instead. E.g temaseks.
so just to make it clear for the dummy kind of user which i seem to be the necessary steps are:
1. getting a stock lp rom and flash this
2. flashing a custom recovery
3. flashing custom rom (e.g. temaseks or standard cm12.1)
Does the Phone have to be rooted for these steps? It looks like it has lost its root status with the update to 12.1 or when i tried to re-flash the broken recovery partition.
thanks for your patience.

Cannot install Android 7.1 (Jiayu S3 MT6752)

Hello,
I tried to install the new Nougat rom for jiayu S3, but it was unsuccessful. Phone got soft bricked, but I recovered it with a twrp backup.
My OS is android 4.4.4, and TRWP is 2.8. After installing the new rom , an installation error appeared and phone did not work.
I wonder it it's due to twrp 2.8, but I can't install twrp 3 (S3_h560_TWRP_3.0.2-0). There was an installation error with flashify...
The question is: can I install 7.0 from 4.4? Is it an Android problem, a TWRP issue, or just my clumsiness?
Thank you!

in short:
To go from 4.4.4 to Nougat you need to go via LP RC5 via flashify using firmware upgrade.
This is because the partition layout is different from KK to LP onwards.
Then you can flash Nougat using TWRP (which will be version 3)
Thank you very much for your answer.
Please forgive me for my ignorance but, which LP ROM should I download? Can I install it via flashify, via TWRP 2.8, o flash?
Thank you again!
You can not use Flashify, you have to do it using Flashtools (with a PC) to go from KK to LP. Download LP 5.1.1 RC 5 from MAD.

thanks to correct me, I thought Flashtools was meant
Well, I'm in trouble now... I installed successfully 5.1 in my S3, but when updated twrp 2.8 to 3.0, it did not work, so I can't install Nougat...
Now I have no twrp, and no root. How can I root to install twrp? I can't install superSU neither....
I'm sorry if it has been already answered but I can't find it.
Thanks a lot
I re-installed LP with Flash tools and everything worked right. (In twrp , it says 2.8 version, instead of 3.0, though).
Now I installed Nougat, and everything is ok.
Thank you for your excellent job!

Moto G4 no longer booting after SuperSU flash

I have a Moto G4 Athene (not Plus, and not Play).
I did the following:
unlocked bootloader
flashed TeamWin recovery
installed SuperSu 2.79 SR3 from TeamWin install
The phone no longer boots. Just a black screen. Flashing notification light if put on USB.
I can still get into the bootloader, and from there into TeamWin recovery, but I'm not having any luck beyond that.
Sadly, I didn't create a backup.
I tried installing LineageOS 14.1, pushing with ADB in recovery, and then installing with TeamWin. Even though I can add the file to the phone and I can run the install, a reboot returns a black screen.
Any advice? I'm afraid this isn't looking too good.
By the way, you can just work with twrp after installing that... stock recovery (fastboot adb) doesn't belong anymore. At first I would suggest that you post the details which are shown in your bootloader.
Furthermore I would recommend just to flash stock rom and testing that case.

First of all, if you read their corresponding threads, you need to do the following when rooting:
- Unlock bootloader/flash TWRP (you did)
- Flash a custom kernel (Vegito or ElementalX)
- And then wipe ART/Dalvik Cache
Second, for LineageOS- you cannot dirty flash custom ROMs, EVER EVER EVER! By this I mean you have to wipe system/data/cache/dalvik etc.- you can ignore Internal Storage and the SDCard/OTG.
You may (should) have to flash the Moto G4 Nougat radio that's floating around XDA somewhere. LOS worked fine for me without doing that, but I know other ROMs require it.
Finally, as a quick heads up, all Moto G4 Plus ROMs work fine with the G4, including any stock ROMs/backups.
Edit: I heavily suggest Magisk or phh SU over SuperSU- Magisk allows you to use SnapChat and Pokemon Go, and phh's is open source.
Thanks for the responses.
I was able to restore the phone with a stock rom I found on these boards. After that, I received two OTA, one to 6.0.1 and then the current to 7.0.0.
I have the same problem than you... Can you send me the link that you use to fix it?

Just flash ElementalX 1.04 kernel (after flashing SuperSu or Superuser or Magisk) when trying to root STOCK Nougat 7.0 as it's designed to thwart any root attempt.

Can't install TWRP higher than 3.0.2.0 & Update to Nougat

Hello, i was using Skydragon 5.1.1 and it started to become slow, got optimizing apps everytime i restarted the phone, and wanted to flash to LineageOS
Figured I`d update TWRP to latest version, so I got that from their site, version 3.1.1-0 and when I wanted to boot to recovery it would become stuck at the bootscreen. Same thing with any other version over 3.0.2-0.
Used FirstAid to revert to older version of TWRP, and managed to install 3.0.2-0 again and boot to recovery normally.
With this version it seems i cannot install LineageOS because it gives an error.
How do I go about installing Nougat ? Thanks !
First u should install the 3.6.0 Firmware then try install Nougat

Always returns to stock recovery

Good morning all,
I tried 2 days ago to upgrade to Oreo and since then all my troubles began.
I have unlocked bootloader and encrypted device.
The problem is that in every reboot a stock recovery shows up ,while i have installed the latest blue spark or any other recovery.
Now i can only install stock rom with no root.

Are you going for root? I think you have to flash Magisk (or other root-solution) in order for your custom recovery to stick.

In Nougat that was not the case,maybe in Oreo there is something different?
I'm having a similar problem! I'm rooted, unlocked, and decrypted but I can't seem to install any Oreo Rom. Do I need to re-encrypt my rom??

No, I managed to load the latest twrp recovery and without reboot I installed the xXx rom Oreo.
After that there was an App installed already called TWRP recovery. Since I flashed the recovery again through that app the problem is gone.
Now I have Oreo xXx rom and everything works fine.
After fastboot flash recovery, reboot into recovery and flash recovery IMG again. Then it will be there regardless of what ROM encrypted or not.
