Problem with TWRP -Solved-

Hi all,
I'm trying to get root access on my OPO, so I read some information about the process.
It has CM 11S R38.
* Update recovery unchecked.
* Bootloader unlocked.
Til here everything is OK. The problem starts when I install TWRP or any other custom recovery (I've tried also with Philz CWM). After the installation (via fastboot) it says everything was correct, but when I restart in Recovery the device just "freezes" (actually is the screen which keeps with OPO Logo) and then it becomes to black screen. After this happens I have to force a soft-reset to restart system.
I've tried to roll back to the stock recovery and it works perfectly. But any time I try to flash the custom recovery again, then blackscreen...
I really want to root my device, but I need the custom recovery to install the binaries.
I would be happy if I can bypass the recovery installation, that's not compulsory for me. My plan was indeed flash the binaries and roll back to stock recovery.
Thanks in advance!:good:

For me TWRP works only on ColorOS but the OS doesn't boot, with 11S the OS boots but recovery doesn't boot.

Wierd Bootloop-Problem when flashing TWRP

Hey Guys,
so i got a wierd bootloop problem and for now i didn't find any solution here on xda or somewhere else,
not even a thread where someone has the same problem.
I'll try to give you as much information as possible in a chronological order.
First of all I got the international model (G920F).
So like 2-3 months ago everything was fine, my phone was rooted, got TWRP working and was flashing Roms with no problem what so ever. TW-Roms like Noble Rom and also AOSP/Lineage OS.
One day I wanted to flash UltImAtE NoUgAt A8 Port and that is where the trouble began, dont think it has something to do with the rom but maybe it helps.
So i flashed the Rom(wiped everything except int. storage), flashing was no problem but it didnt boot.
I know first boot always takes some time but after about 20-30 min I forced a reboot (Power+Vol. Down for 7sec).
After that the phone got into a Bootloop(always rebooted into the "first bootingscreen")
I let this process happen for about 15 min. and then tried to enter TWRP via hitting the buttons between the boots which didn't work. I then did "force" a reboot(Power + Vol. Down) which strangely resulted in one final reboot and turning the phone off after the first bootscreen.
So with the phone finally turned off I was able to boot into TWRP and reflashed the rom but the result was the same.
I did the same procedure again to get into TWRP and flashed the Stock Deodexed TW Rom, flashing worked but then the Phone directly rebooted into TWRP. Rebooting out of TWRP or booting the phone from beeing shut down both resulting into booting to TWRP.
So to get my Phone working again I had to flash stock ROM which in my case is G920FXXU5EQDF_G920FDBT5EQD1_G920FXXU5EQCD via Odin.
That worked but of course root and TWRP were gone so I then flashed TWRP via Odin(both newest Versions at that point)
aaaaaand phone straightly booted into TWRP again all the time. I tried different combinations of older versions of both twrp and odin but the result always was the same.
So at the moment I am on Stock, the phone works which is nice but i really wanna get TWRP working again and i have no idea what to do.
I hope someone can help me with that.
Cheers Guys

You do know that if you flash TWRP, you need to use a kernel that has dm-verity disabled or you need to be rooted. Flash TWRP then Flash Magisk through TWRP

As it seems I did not, good thing that its written right at the TWRP download page...
Can't remember doing this when I installed TWRP first but as it seems I did.
Everything is working fine, just flashed Nexus OS and it booted.
Thank you so much dude

Stuck on LineageOS boot animation (first boot taking 1h+)

Need some help, I keep getting a infinite boot animation. I tried to install LineageOS (thread) on my G920F three times and let them all boot for about an hour without success.
This is the order of how I flashed it:
1. Wipe Davik, System, Data and Cache
2. Flash the LineageOS zip
3. Flash the Zerofltexx kernel img
4. First try flashed OpenGAPPS, second try flashed MindTheGAPPS and third try didn't flash GAPPS at all
5. Reboot and wait, after an hour still booting
Any idea's of what I'm doing wrong?

Fixed my issue!
Hi!
I had the same issue as you, followed the guides and installed TWRP through ODIN and flashed the OS through TWRP to boot it.
When I booted the device it just got stuck indefinitely on the loading animation (the Lineageos loading logo in my case).
Since you and some others had the same issue as me I assumed it was something to do with a new version of some software.
I resolved the issue by installing an older version of TWRP through ODIN,
I installed the TWRP version 3.2.3.
And then I flashed the same ROM with the GAPPS again.
After the ROM and GAPPS I also flashed MAGISK aswell from the magiskmanager website.
Download the MAGISK Zip.
After I flashed the ROM, GAPPS and MAGISK through the TWRP 3.2.3 it booted as intended.
Hope this works for you aswell!

how long did it take to boot

First Boot needs longer...up to 15 minutes is possible.

Remove the TWRP from the phone via the advance key in TWRP. I had tried several ROMs and Gapps only to get stuck on the boot screen then back to the TWRP screen. Removing the app made my new rom boot in less than 10 seconds.

If you can give us exactly the steps you follow

Lineageos 17 boot animation stuck

Steps (I have followed the instructions to the letter)
Wiped all partitions (advanced wipe)
formatted DATA partition
rebooted back into recovery
installed Lineage 17 and Gapps
Rebooted to system and left it all day, still stuck on boot animation
Tried again without gapps same results
Tried other roms they work, AOSP showing no encryption which works fine
What am I doing wrong? Do I have to flash different kernel? TWRP 3.3.1 installed.

Im using G920L it booting to long then just go to twrp anyhelp?

For reference, formatting data after install seems to often be the solution when flashing a new OS to a Moto G5 Plus.

Random continuous reboots on Unstable OP6 - HELP!!!

Hi everyone,
I'd really like some help here.
I have an OP6, 8gb/256GB.
My OP6 suddenly started crashing and rebooting randomly after the update to 10.3.1. It seemed fine before. I did a full factory reset and the problem was not resolved.
It is especially bad when i turn on the lockscreen. So i turned it off and did not turn it on again.
The apps that would crash were random including oneplus launcher, google playstore, and other google apps. the issue remains when I do the factory reset and do not install apps. It is a bit more stable when I do not login to a google account. Even the basic set up leads to multiple crashes and reboots.
The problem continues after i have tried all the steps below.
1) msm downloader to downgrade to OOS9. Worked better, with less frequent reboots, but problem continued.
2) I did a remote session with Oneplus, they installed OOS9. After the install, it restarted, got to the start screen and then rebooted. I was able to complete basic set up. but Problem continued with other apps even though I installed them one after the other and did not enter my google account credentials.
3) did another factory reset and upgraded to 10.3.2. appeared stable but restart was also off as it would reboot every 2 steps in the process. Problem continued
4) I unlocked bootloader, rooted the phone and tried a few roms. With OOS 9 fFastboot, all roms failed to start and put the phone in crashdump mode. I installed the roms using instructions on each rom page. basically, flash the oos, twice, flash twrp, go to recovery, flash rom, flash twrp, go to recovery, flash gapps, flash twrp and then reboot system. When installation failed or rom did not work properly, i would reinstall the fastboot file and then start over.
5) I installed the fastboot 10.3.2 on both slots (tested by booting it from a and then from b). I used twrp 3...18. and flashed pixel rom, bliss rom, lineage os, illusion rom. Lineage and bliss were most stable with little rebooting but the problem still occurs.
6) As of now, I upgraded to the 10.3.2 OOS using the fastboot file. I flashed it twice for good measure. I was able to install my apps and stuff using google setup. But phone is flickering randomly and problem has not been resolved.
I'd appreciate any help to get this good looking phone back to work!

Ur problem is you don't want to format data when switching ROMs (at least not all ROMs) it's safer to just wipe data instead.
Flash OOS
Flash TWRP
Reboot recovery
Flash OOS
Flash TWRP
Reboot system
Complete initial setup
Reboot to recovery
Wipe (not format) data
Flash custom ROM (start here for dirty flashing ROM update)

I have already tried wipping cache and dalvik cache, I even wiped system and data and installed the ROM again but the phone's still stuck in a bootloop.
Now I'm about to flash through Odin back to stock and see if the phone turns on.

Hm... While I was downloading the stock firmware to flash the phone, I thought of checking the data folder inside the TWRP recovery, And turns out The data is still there, It never got wiped, that's why the phone is stuck in a bootloop, Now what could be preventing the data from getting wipped? I don't get any errors when I wipe the data partition, And this is also strange because usually you get a bootloop when you flash some kind of zip file through the recovery (mods or something like that), but I was just using the browser to download a file , And phone suddenly shutdown and got stuck in a bootloop, Could someone pls help me figure out what's causing the problem

That ROM is in BETA mode, which means it could be lost of things. Your question should be asked on the LOS 17 thread itself but when a ROM is in BETA mode it's very difficult to tell what the problem is. Ask the developer @ivanmeler he might be kind enough to answer you.

Sorry but I don't have enough knowledge to help with kernels, Now from what I understand is that you tried flashing stock ROM and your phone got stuck in a bootloop, Right? And just to confirm could you mention the model of your s7?

Flashing stock rom will restore stock kernal. Firmware must be correct for device and region.
Bootloop after Odin Flash.
1. After flash boot into stock recovery
2. How to>>> In this sequence hold volume down+home+power. As soon as phone goes off move finger to volume up while still holding home and power. It may take several attempts as you have to time it just right when the screen goes black.
3. Once in stock recovery choose wipe data/ factory reset. Then choose reboot device
4. Can take 5-10 minutes on first boot. Updating and erasing screens are normal during this process as well as rebooting. Just leave it finish.
If this does not work Reflash stock with Odin but this time uncheck "auto reboot" in Odin options before you start.
Once Flash finish, disconnect from pc and follow 1-4 as above.
