[Question] How do backup from persist partition on redmi note 9S - Redmi Note 9S / Note 9 Pro (Indian Model) Question

hello friends I wanted to ask if it is necessary to make a backup of the PERSIST partition? or is there no risk of losing it during a bad flash? I saw your online but they are for other cell phones. And the ones I saw use the terminal, but they are all different between devices.
I await an answer and I greet you at the beginning of the year, wishing you the best for you. I am sorry for my bad english.
PS: In recovery mode this PERSIST partition does not exist

If you don't do something extremely stupid like wiping the super partition or using fastboot to specifically wipe persist. Nothing bad should happen to it.
If you still want to be super secure, take a look at this guide here

[Q] I can't delete, or put anything on my atrix.

Hi, this is my first thread.. I'm from Argentina so i'm sorry for my bad english..
I've problems with my atrix ATT.
Since a week i've been tried with GB roms and ICS, JB, but yesterday, I realise that couldn't erase anything, i tried to erase internal memory from the phone, even from the computer.. It looks like it makes the erase, but when I rebooted the phone, everything it's like before..
I tried Wipe data, wipe cache, wipe dalvick, and when i reboot, again, nothing happened.. It's just like before was.. I tried erase with scripts, with fastboot, but nothing.. I tried to flash some rom's again but i couldn't..The phone flash the roms, but when it starts, it starts like before, nothing changes.. The phone is working, and fine, but, i can't change roms or put files into the internal memory because when i unplugged the phone from the computer, the files are not there.. It's like the internal memory is in only read mode or i don't know..
When i tried to restore my nandroid (in other times it worked fine) when must to restore data it says Error while formatting /data! .. I tried from advanced in format data, but it says Error formatting /data.. I know that i can't flash the original firmware because i've unlocked the bootloader, so I beg you for a solution.
I really would appreciate your answers, and more if they are in basic english... hahaha
PD: i think it's in the correct section, i apologize if it's not there..

Do you have root access? and if so your apps may be stored on your sd card wich would cause them to stay after a data wipe.
fastboot erase everything except radio , including sdcards and do frash nandroid . Maybe it could help !

I tried with fastboot, but nothing happens either ..
It seems very likely this is a hardware failure. Not sure there's anything you can do, other than send it in for repairs...
In which case they will very likely either replace the motherboard or just give you a new phone, in both cases you might end up with a nonunlockable BL.
Sucks, I know.

i'm looking everywhere for a solution, but don't find it.. My warranty is void now, and a change of mother board would be too expensive I think.. I know that this is crazy (having an unlocked atrix 2.3.6), but i think that i don't have other option that trying to flash the .sbf 2.3.6
Do you know someone who did that?

I am having this exact same problem
Epinter cm10
cannot format, cannot flash, errors while booted up
It looks like a problem with mounting data drive, or some problem with the data portion itself.
When i wipe, nothing happens, if I try wiping individual drives, I get errors when trying to wipe /data and /cache.
If I try rebooting into fastboot, it wont detect it on my PC (and it seems to get stuck at starting protocols on my phone).
All in all, I have no idea what the solution is, or even the problem... but this certainly doesnt sound good :/

Hi,
Downgrading in general is almost impossible. You might need to do a full wipe. Sometimes it may work without, but you may experience strange problems and will spend more time on solving them compared to a clean install.
When changing ROM editions, you should also format the system partition (TWRP -> advanced wipe, you might find something similar in other recoveries).
Perform a full backup first and keep it on a safe place. It's also recommended to keep a backup of the EFS partition (if you don't have one already).

Not true. ...
You can always downgrade.
Just do a factory reset and full wipe before.
Repair a imei nr. just search the hundreds post here on xda.

Sure, that's what I meant with "formatting the system partition". I just wanted to mention that this is not something like a "smooth" downgrade where you switch to another version and everything else can remain. The term "downgrade" may imply that you just "change" something. In fact you setup a new phone.
Sorry for confusion.

Watch out what you advise people.
"Formatting" is something else as doing a wipe.
My system is formatted to f2fs file system.
If someone tick the option to format the system in odin it good end up with a brick.
Then you need to flash a rescue system with pit file.

While I was talking about TWRP, I thought this was clear. However, I should have used the correct term. You are totally right. Will try to be more precise in future. Thanks for the hint.

Remove Android from phone

Hello!
Please excuse me and my language. I am also kind of a noob.
Is there any way to completly remove Android from smartphone?

I find the best way is either letting it go for a swim or run over it with a large vehicle. But seriously, what do you mean by that? It's like asking how to remove Windows from your PC. There wouldn't be anything on it to actually use the device.
Wipe partitions
I want to wipe all my partitions (including the kernel) in order to reinstall my firmware. I have rooted my phone and messed up with some kernel settings. I want to erase everything so I can start over. I may be a little stupid to ask for this but sorry. I am a noob. Is there any way?

For most devices, this is not necessary - to wipe everything. Rarely would you ever need to wipe the boot partition (where the kernel is stored), as just flashing another kernel, rom, or reloading the stock firmware with the appropriate tool would take care of this. Why don't we backup a bit and start with which device do you have, what update was it on before you started, and what have you done to it (which rom, kernel, etc) as any or all of those things can affect which steps you should take to resolve your issue.
Fixed it!
Nevermind.. I fixed my issue. There was a problem with com.android.systemui. And about partition wipping.... I managed to do that with SP Flash Tool from MediaTek
Thank you for your support!

[Q] Is "L Speed" compatible for any note 5 device now?

I am using note 5, SM-N9200, Samsung stock rom, rooted and TWRP recovery installed.
Does anyone, especially the owner of L Speed, can tell me the answer of the above question?
Thanks for any help!
If you can't find that info in the thread about the tweak, then you can just do a nandroid backup in TWRP and try it yourself. Worst case scenario, with a mod like that, is that you might have to restore your backup and the only thing you have lost is a few minutes of waiting for it to restore and reboot. That phone is crazy fast with those kinds of operations, so shouldn't even be down long if it does not work well.

Bootloop after removing finddevice on miui 10

Device: Redmi Note 4X (mido), Android 7, MIUI 10
Hey! Pardon me if I've placed my thread in an inappropriate place.
So, what I did was remove the system's finddevice app.
Then on some forum I read that it will cause a bootloop (phone is still on, working at this point). So I backed almost everything up and, in a moment of brilliance, went and rebooted the phone, at this point I went in and made a TWRP backup of the whole thing too.
I've got an unlocked bootloader and I am here for ideas what I can do with that in order to somehow fix my broken system. I know that I can just do a factory wipe, but since I only made a MIUI local backup prior to turning the phone off, that would mean setting up a lot of things from scratch, and also I see it as sort of an experiment to try and revive the dead system.
What I've tried is doing a wipe and only restoring the data partition from the old system. This doesn't seem to change anything.
I also tried making a backup of a working system and then recovering only the system partition of that, onto the broken version.
My experimenting leads me to believe that the data partition is indeed the one broken.
I will be interested in reading what you guys think about this.
