[Q] Need help with a bricked i9100

I was running Resurrection Remix on a Samsung Galaxy S2, which was working well, except that it was not compatible with one app. The apps developer recommended flashing Cyanogenmod. I picked CM9, because I didn't find a stable CM10 mod. Anyway, I proceeded to install CM9, and GApps. The GApps version I used was not the right one, and I rebooted without installing the correct GApps. Now, when I boot the phone, I cannot get into recovery mode, and it only displays the Cyanogenmod 9 splash screen endlessly. Kies cannot see the phone, nor can Windows 7. Is there anyone who can point me to directions on how to unbrick this phone?

Need a few questions answered to getting to stock and then custom ROM

I'm confused on a few things,
I once had Cyanogenmod with Marshmellow, after updating to an OTA Cyanogen version I got stuck into bootloop and for some reason I couldn't get back to Cyanogenmod in TWRP recovery and the only nandroid backup was B331 which is only Lollipop Stock which i'm currently on. Now I just want to start from scratch and get back to latest Cyanogenmod with Marshmellow. Where do I start? I have Current Build KIW-L24C567B331 that is currently Lollipop and I wiped my internal SD. When I try and look for Stock OTA updates it says no updates, the update client has NEVER worked on this phone. I have currently TWRP recovery on it. Do I have to go to a certain build to get back to Marshmellow? then go to Marshmellow Stock then to Cyanogenmod?
I tried following this guide: http://forum.xda-developers.com/honor-5x/how-to/guide-kiw-l24-to-stock-t3318268 but I don't understand which stock I should go to and the instructions aren't very clear (maybe i'm just dumb)
Another question: for each Custom ROM I install do I go back to a certain stock build then flash the custom ROM?
Much help appreciated,
Thanks
Are you in stock Marshmallow before you flashed CM?
Sent from my honor 5X using XDA Labs
if you are saying that you have twrp, with lollipop emui on, due to twrp, you will never get any update,
since you want marshmallow, i think you need to be upgraded to marshmallow firmware,
to do so, you need to download the marshmallow build, generally the b331 firmware in the link you provided...(dated:10/07/2016)
go ahead and download that firmware and follow the procedure, in the end, you will be left with the marshmallow emui build with stock recovery on (eligible for ota and warranty )...
now, since your bootloader is still unlocked(i guess), you can reboot to bootloader and fastboot twrp recovery(latest twrp is recomended)..
and now, you are pretty much good to go.... download latest cm13 nightly and install... enjoy
please do perform the steps carefully:good:
AND NO, YOU DO NOT NEED TO GO BACK TO A STOCK BUILD TO FLASH CERTAIN CUSTOM ROMS

Flashing a different Custom Recovery without a charging port (Broken charging port)

So i wanted to install custom rom(cyanogenmod 14.1) on my S3 device I realized that my device has already CWM (v5.5.0.4 :: CF -v1.5 ). I can flash cyanogenmod 14.1 with no issues but I can't flash gapps. After installing gapps, I get a lot of errors when I boot(Setup wizard has stopped). I tried 2 different versions of gapps(aroma,nano) both of them didn't work. I started to think that my CWM version is the issue. I want to flash another Custom Recovery like newer version of CWM of TWRP but as I said my charging port is broken. I just want my device to have android nougat with google apps. I hope I can find a solution
Download the TWRP App from Google play and install. You could also search for a flashable TWRP recovery und Update within TWRP to latest version by flashing the .img file.
The problem wont be the recovery. Make sure gapps is the correct one for your device. Check the software versions and cross reference them against Apkmirror.com.
Beamed in by telepathy.
That's a problem of Cyanogenmod 13 / 14.
Wipe your Cache/System/Data Partitions and reflash Cyanogenmod 14.1. Then don't boot up, you've to install the gapps package directly after that.
Make sure that you have downloaded the ARM 7.1 gapps-package.
You can flash twrp or stock rom from 'mobile odin'. Or you can download flashable twrp.zip....but flashing stock ROM requires additional download
I solved the problem. The problem was recovery and i knew it. I downloaded the apk of TWRP App from their official website. It worked flawlessly. After that i Flashed Cyanogenmod 14.1 then gapps with the latest version of TWRP and perfect! Everything works without any problem. I hope this answer is helpful for the other people having the same issue.

Messed up a ROM install, now can only install Pre-Pie ROMs.

I installed the 5.8.020S ROM (Stock EUI) for Le 2 instead of Max 2. Luckily it didn't brick my phone.
When I tried to roll back to Lineage 16.0 (Pie) it didn't work. Tried a bunch of ROMs, Lineage 15 works, some others work but no Pie ROMs. My phone also resets itself on Lineage 15 every few hours for no reason. And the pre-boot screen has changed to a penguin instead of the "Le Eco" one.
Is it possible that when I installed the Stock EUI ROM that the boot partition and kernel were altered and that if I can get those back it will fix all my issues?
Or is it more likely that this is a hardware issue/irreversible?
Any suggestions? Thanks a bunch in advance. : )
Heyyo, boot partition is the kernel partition, so that should be overwritten by new ROM installs so that should be fine.. but yikes! I'd highly recommend using a fastboot ROM installer for EUI ROM for x2 just to ensure your device is as x2 as possible.
You could try this one from cuoco92 and use a PC with fastboot to install it. I believe there is readme files for instructions on how to do so.

If that fails? I would recommend qfil which will guaranteed reset your device to x2... albeit, with an older x2 developer build based on 5.6 I think? So from there I'd recommend upgrading to EUI ROM based on 5.9 like 19s and up before swapping to a custom ROM if you wanted to go that route.

Good luck!
It worked! Lineage 16.0 installs and runs just fine!
Also the stock ROM fixed my camera issue (original reason for going to stock) but lineage broke it again. At least I know it's not a hardware issue.

Updated to Android 11

Hello,
i need your help.
I flashed the latest update for the Galaxy Tab S6 with android 11. I fully wiped everything and i want to root my device again. (was already rooted in Android 10)
TWRP has now a offical Recovery Support so i flashed this one instead of the unoffical one.
Worked well and booted directly into Recovery after flash.
I did the common things: format the /data partition, system’ partition is unmounted
Then i flashed the Encryption-disabler file first, then WETA_Kernel_T860-7.0_TF2 and then Magisk.
After that i rebooted my device, but somehow my device is stucking in a loop now.
Do i need any wipe?
Is android 11 the issue?
Is the WETA Kernel 7.0 not compaible with Android 11?
I dont know what i do wrong honestly. I did the same thing, when i updated to android 10 and everything there works
Any help is appreacited.
Thanks in Advance
