Can't boot system and/or TWRP running on SM-A12F - General Questions and Answers

I decided to root my phone with running latest version of SM-A12F, but ended of the following:
System: One UI 3.1
Currently Running about
Android Security Patch Level: October 1, 2021
Additional: Unlocked OEM Unlock(Grayed Out), Device Unlocked
Attempt 1. After flashing twrp(many times, but different who bulid twrp), can't boot system. So i decided to flash stock recovery and goes running normal.
Attempt 1b: I flashed multidisabler with twrp but can't boot system and restart freqnently.
Attempt 2: After flashing twrp and vbmeta, booting to TWRP successfully but can't boot System.
Attempt 3: The basic solution about rooting with magisk was successfully but after an hour Google Services got often stopped and Google Apps too. I decided to restart and got warning message about "Security Error: only official BOOT to solve the solution", so i decided to roll back to reflash a new firmware.

[SOLVED] Serious problem - can't install any rom

Hello,
Today I've been trying to root my HTC One S (S3) and install CM11 (cm-11-20140210-SNAPSHOT-M3-ville)
1. I made successfull S-OFF

"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
2. Installed wrong recovery (r2-modaco-recovery-clockwork-touch-ville.img)
3. Then installed correct (working) recovery for s3
4. Flashed my boot - fastboot flash boot boot.img
5. Made backup
6. Factory reset (everything)
7. Tried to install cm *.zip but here it is (tried also another CM's):
What is more phone freezes during start, display non-stop the same:

did you downloaded the rom fir your device ?
cause, as i look at your pictures, that rom isn't for your device, see picture number 2,
or there's something wrong at updater script, contact your rom developer about the updater script
edit : you can aslo try to replace your recovery with the others, maybe it's the problem too
http://download.cyanogenmod.org/?device=ville
Here is source of my roms. However there is no info if they are for s3 or s4 ..
Problem SOLVED
ROMS located on the cyanogenmod site are for ville (but not ville c2).
I used "Stable: cm-11-20140110-UNOFFICIAL" from http://forum.xda-developers.com/showthread.php?t=2527962 because it's especially for C2
Before flash I had to flash the kernel file from THIS NEW version
Then made factory reset in TWRP 2 Recovery (versions for c2 - http://techerrata.com/browse/twrp2/villec)
Finally, installed the rom from xda and everything works fine !

LineageOS 14.1 stuck in fastboot & rescue Huawei mode after successfull installation

LineageOS 14.1 stuck in fastboot & rescue Huawei mode after successfull installation
Hello, people,
I did comprehensive research how to avoid fastboot & rescue mode after successful LineageOS 14.1 update, but still cannot boot the installed LineageOS. I already executed the following steps:
1. The phone is already unlocked. (Huawei Honor 4/4x)
2. TWRP downloaded and installed, version 2.8.7.0, already has been used and through it has been installed one of the previous releases of LineageOS 14.1, successfully running for more than a year.
2. Downloaded latest compatible LineageOS 14.1 .zip for Honor 4, and for my model cherry. (already has been installed on my Phone a 1 year old version)
3. Downloaded LineageOS extras, su-root, etc.
4. Downloaded Gapps, compatible for my model AMD.

5. Advanced Wiped: Dalvic Cache, Cache, Data and System.
6. Installed all above mentioned downloads in the following order: LieangeOS su-root extras, LineageOS 14.1 (lineage-14.1-20180410-nightly-cherry-signed.zip), Gapps.
7. Scripts output: successful installation.
Unfortunately after reboot the phone stuck in fastboot & rescue mode, and cannot boot the installed LineageOS.
Here you can find the system recovery.log and open_gapps_log.txt from the installation.\\
It's seems like a selinux permissions failure.
Can't check permissions
after Factory Reset.
Please boot rom and try
again after you reboot into
recovery.

Do you have an idea how to fix them, I cannot find solution within xda forum?
Any suggestions will be appreciated!
P.S. Do not recommend to backup to the phone original firmware.

Question The system cannot be updated

T-mobile version! After the phone is rooted! Click update and download in the system, then insert an empty slot in magisk, restart, and check the system version number, which is still 11.2.2..2! The system update still prompts 11.2.3.3 update! Unable to update the system now! Flashing back to boot.img without a patch still cannot be updated

Your probably gonna have to do a complete uninstall of magisk. Reinstall original boot image then take update . Reflash patched boot image of update to regain root. Just my thoughts.
I had to completely re-lock my bootloader and factory reset to be able to take the update. Make sure your boot.img is stock before doing this though, as having a modified one will render the system unable to boot (you can still access the bootloader, though).

OK!I flashed my phone to the international version based on this GUIDE,Guide reference . and then updated it to EU 11.2.3.3, everything worked normally
And that worked for the TMO 1+ 9?
Yes, I updated it to EU

Question Rooting attempt ended up with no playstore

I recently attempted to root my op9 following the guide in the pro forum after booting a rooted bootloader and installing via magisk everything seemed fine, I actually use my phone a lot for contactless payments so I needed to pass safetynet and this is where everything went wrong, I followed the magiskhide guide and hid from gms and proceeded to reboot.
When my phone booted up I had lost the playstore and my phone was no longer rooted to make things worse safteynet failure.
In the end I had to flash a standard bootloader into both slots and relock my bootloader just to get stock working correctly.
What could I have possibly done wrong to lose playstore?
Fixed the issue partially following the rooting guide on the pro forum
[GUIDE] [Magisk] [Unlock / ROOT / Keep Root] OOS 13.1.0.500
Different variants of Magisk that are available for use : Magisk Variant Stable / Beta / Canary Release Official Android / OOS OOS 11 and above Maintainer topjohnwu Project Link GitHub Zygisk No...
forum.xda-developers.com
I restarted the process after I factory reset and updated to LE2113_11_F.72
extracted the boot.img and patched it and finally got everything working...
it's been a while since I've rooted anything and the whole ecosystem has changed but I still managed the basics My only thought is I used the wrong bootloader.
