Some questions about rooting, custom roms etc.

Hello.
First I'd like to say that i haven't ever tried anything like rooting my phone or custom roms so that you know what you're dealing with
Lately I've been bored with my s8 plus(SM-G955F). Was even considering buying a different phone but then i remembered reading about rooting and custom roms so i thought i might give it a try.
I've been reading a bit about rooting and roms but all the information and methods can be a little overwhelming for someone like me who doesn't really know what he's doing. Basically i need help.
While looking for custom rom i'd like to try i settled on renovate ice and i have some questions.
Do i need to root before flashing a custom rom or does the rom come rooted already?
From what i understand i have to start with installing TWRP with odin but what then? root or rom?
Basically if anyone would be kind enough to provide some links with steps i need to take to install that rom and root my device and not mess it up i'd be grateful.
In case you need it I'm on the latest OTA i've received.

Hello there , you do not need to root your to flash a custom rom . All you need is to backup your data for you own safety and flash TWRP recovery through Odin probram . Renovate ice is most famous and stable rom you can try . It has same UI as the stock rom . Little changes only you might wont see me . If you want to change UI you should for another rom . Also root comes with the rom inbuild, specificaly renovate ice has two options to chose, magisk or supersu . Personally i prefer Magisk before through this app ' you can' modify your system, its like xposed framework.

So I installed TWRP like in the video.
Everything seemed to work i had a clean install of stock ore with twrp. When i tried to boot into twrp i had the "only official binaries" bootloop. So i flashed a bootloader and i was stuck on galaxy s8+ screen. Went into download mode to flash stock firmware but can't do anything. Stuck in download mode and can't flash anything now... How do i get out of it?
Edit:
Ok. Found a way to flash the bootloader. now I'm back to "only official binaries" bootloop.
Edit 2:
Ok managed to get everything to work. At least it appears so for now.
Had to flash nougat firmware then installed twrp, rom and root and it worked.
I thought something went wrong because it was very laggy but after rebooting it seems okay. We'll see how it goes from here.
Gonna google it and try to fix it but if anyone has any ideas i'd be grateful

Android Q update and Rollback

Hello,
I tried to install a custom rom on my phone, but i never achieve it...
I always stuck on booting screen (soft brick).
So i decided to flash official rom with miflash.
I had a rollback error (rollback version 1).
So i remove the check in the all_flash.bat file
I made the flash successfully.
I tried to install the zip file for android Q and i got this error in picture attached.
looks like current android version is different from that in the recovery package
Any idea how to fix it?
Rollback anti is still 1.
Thanks guys!
There are Global and EEA official Android 10 ROMs. Check if you pick the right version with your actual ROM version.
Thanks for your Reply.
My phone is in PDJEUXM rom ans i have download SFJEUXM.
so i think i pick the good one...
PDJEUXM
SFJEUXM
LOL what??
I think it's not possible to install the eu rom cause it's a beta rom.
Until we get like a version 11.0.4.0 or something Higher i think it's impossible to install.
Welcome to the K20 or Mi9T Forum!
Redmi Note 7 isn't here!
Finally, i install it using TWRP
Thanks for the help guys!

need help

Hello friends,
I hope you can help me understand if it is already explained in any thread of this forum, I had the rom stock 8 with turbo game installed, it gave failures and I decided to try another rom install twrp 3.2.3.0-hi6259-askuccio-v1, clean and install the rom lineage 15.1 the most recent but I no longer load the start logo when in the previous version if I loaded it now I do not load anything from used erecovery to restore a rom stock b366 my doubt is if there is any way to return to Try a custom rom and I did everything again from the bootloader to install in this official rom stock, if it will not be a nuisance to be stuck in roms stock when I have worried other beautiful roms.
by the way my device is WAS-LX3 AT&T Mexico, I am currently stuck in the rom stock WAS-LX3 8.0.0.366 (C212CUSTC212D001)
first of all, Thanks.

Twrp for 11?

Hey guys,
Anyone have any info when either unofficial or official twrp is coming for Android 11? I made the mistake of upgrading to 11 from 10 then tried flashing twrp which bricked my phone ( I fixed it, no biggie ). I just really want to flash a custom ROM and I can't find any other custom recovery that will do that and side loading twrp also gives a crashdump error. Unless anyone knows how to downgrade to 10, the the furthest downgrade I've achieved is 11.0.0, once I hit 10.x.x I get either a black screen or crash dump.
It's a lot there, I know. Much appreciated everyone.
Edit: reading more on this forum, I think I found a way to flash a custom ROM on Android 11.. I guess you can side load roms? So I guess I'm going to give that a try. I'm so old school, like back in 2011.
I had the same problem. Im using the Lineage recovery atm an idk why tbh. I think i used it for rooting and for now im only using magisk modules to obtain some featurers.
Sideloading roms is a thing but man i miss those old HTC Hero., HTC Desire times. Last years i was using a P30 pro without root and im so happy to have root again.
Anyway read carefully and have fun. I would love some answers from your experience here.

Most custom roms include all the files needed to flash the entire rom from a batch file. CrDroid for sure, but also Lineage. I'm sure there are more. My issue is not flashing, it's that all important nand backup from TWRP I miss the most. Switching roms is a lot more tedious when you have to re-install everything to revert back to your old setup.
Twrp for 8 and 8 pro may not happen ever, encryption is the problem
TWRP doesn't look promising considering the time that has passed since 8 launch...

First custom rom flash help please !

Hi guys,
I am a long time rom flasher. My wife has a Poco M3 (citrus?) and would like to flash it with CrDroid since she's experiencing some lags with MIUI (12.5.8.0 RJFEUXM UI).
I have looked everywhere for hours and still can't figure out answers to these questions, can you please help me ?
- Can I flash CrDroid Android 11 over her curent stock version ? (I just want something very stable and reliable)
- Any better rom (even on A12/13) ?
- Any link for a working recovery ? (can't find that for sure)
- Do I need to flash anything else like vmbeta, verity no encrypt... ?
- Any comprehensive first flash guide even from another thread ?
I want to avoid any bootloops. I have already unlocked the BL via MiUnlock.
Thank you very much for you time
