I am sorry if there was questions before but i read a ton of articles and don't know which one to follow because I am noob, so please if you can explain me step by step what software do i need or whatever. Thanks in advance!
Any help will be appreciate it!
Its miui 12 no roms or anything
and ye I hope that I put question at least on right subforum

Simply flash new software with Xiaomi flash tool. Remember your bootloader should be unlocked if you want to flash "stock ROM"
However, if you're device's bootloader is not unlocked you have to use the test point method or EDL (Emergency Download).
Hope you're problem gets solved.
Good luck!

[Q] soft brick everytime i try and enter cwm

So ive rooted the phone and checked it with root checker says im properly rooted and bootloader is installed properly also. Ive followed instructions on the forum and even watched some step by steps on youtube. My problem that keeps occurring is when i try to enter cwm any which way it softbricks my phone. Ive found a way around having to odin, you just have too put the phone in download mode for 5-6 mins and then hold the power till it brings the battery up, if the battery actually shows its charging you did it long enough and go head and hold power to restart. Ive had to do this like 5 times already and dont know what could be wrong. Any help would be greatly appreciated!
Thanks vguaderrama
This belongs in General, not Development.
Entering CWM would not in any way soft brick your phone, flashing roms can, but not entering CWM. the hard key combo to enter cwm is VolUp+VolDown+Power+Camera, which should work, even if you're soft bricked.
If you were really softbricked, letting it sit in Download Mode wouldn't help without using Odin.
sorry new to posting usually can get most things on my own just from reading thanks for the help tho really appreciate it.

To enter recovery its just Vol Up + Vol Down and power
Touche, I've been holding an extra button all this time...
Hold +/- down like it was a button

You have to hold the volume button down completely not just up or down, plus or minus, press the whole thing down as if it wasn't a multi fuction button.
What's happening?
When you try to boot into CWM, what happens? Do you get a black screen, the sidekick 4g logo or...? How did you install CWM?
I had a problem when I first installed CWM where it would hang on the sidekick 4g logo. It turned out that when I used adb to push the recovery onto the phone it set the file permission as read-only. I used the adb shell to change the permissions ("chmod 755 /system/bin/recovery") and it booted after that.

[Completed] Android boot loop - is my device dead?

Hello All,
This is my first post at this forum.
I've come to a point where I'm on the verge of giving up.
A few days ago my Nexus 5 entered a boot loop without me doing anything special with it - it was just in my pocket.
All see is the google logo for a few seconds , then the screen goes down for a few more, and back to the google logo.
I'm able to go into fastboot by hold down the volume down (only) button when this happens, but the boot loop happens when I choose to boot into recovery mode.
My device has an unlocked bootloader.
I have fast boot access and no ADB (ADB wait-for-device doesn't work).
Went over a tutorial from androidforums.com and flashed a completely new image using fastboot.
The entire process worked, but the phone is still at the same state.
I've read that there is and issue with the power button on these devices - so I tried all methods of knocking it against stuff without success.
I've taken it to a lab nearby and the guy there was sure it was the power button. He said he fixed about 50 of these already - after a few hours he called me up and said he had replaced the power button 3 times and he's giving up.
in short , this is the current situation :
1. Device stuck in bootloop - only google logo is seen
2. can boot into fastboot (and have fastboot access from PC) but can't boot into recovery
3. flushing a stock succeeds but won't help
4. power button seems o.k.
I am about to call this a bricked phone and look for a new one but something inside me tells me that this might still be a software issue and can be fixed.
I would be happy to know if there is a way to know what is failing in the boot sequence. or maybe load a debug application on to the device to check the HW. I've yet to find any help in that direction.
I'm a software eng. working in the cellular comm. field, so I'm up for anything that anyone has in mind.
Thanks,
Ran.

Hello, and welcome to XDA!
It does sound like a hardware issue and it could be the power button, except for one thing: wouldn't a held down power button in fastboot cause a shutdown as well? Maybe not, but I thought I'd ask that.
At any rate, better to get an opinion from someone who actually has the deivce. Please create an account (so you post in other forums) and then post in this thread (can copy and paste from here):

bricked my A9

dottech.org/189086/how-to-install-twrp-recovery-on-htc-one-a9-guide/
I was following the guide at the above link trying to install TWRP on my A9. I had already successfully unlocked the bootloader through the HTCDev website. When I attempted to install TWRP , it failed due to S-ON error. Now it is stuck on the initial boot-up screen that says HTC, has a white background, and says powered by android at the bottom. Additionally, now that screen displays "This build is for development purposes only. Do not distribute outside of HTC without HTC's written permission. Failure to comply may result in legal action." in red letters. I have tried every combination of button pushes that I can think of in an attempt to power it down or restart it. It is stuck on that screen and will not respond. At this point I am just waiting for the battery to die.
Has anyone seen this before or have any suggestions. Thanks
don't understand why this guide makes you flash a boot image if you just want TWRP...
Once you're unlock, the only thing you need to do is flash TWRP from the official thread you'll find on this forum (i suggest the 2.8.8.0 version, seems to be the most stable).
You don't need to be S-OFF either...
You should still be able to boot on download mode to flash the recovery again. I've already been on that situation and I managed to get to the download mode by pressing at the same time power + volume down and holding after having restarted the phone with the power + volume up pushing and holding.

Probably because most of these 'How-to' pages are copying from each other and most of them describe not only the installation of TWRP, but also root (su). It is a simple catastrophy how many 'half cooked' and wrong descriptions are out there. I was roaming the net for 3 days now and I'm more confused than before ...
Actually I have my A9 only a week and experienced the opposite . I wanted it to be TWRP AND ROOT and found a page, that didn't mention the modified boot.img. Now I have NO root and wonder, whether I still can flash the altered boot.img (and which! Are all boot.img for unlocked A9s equal? There seems to be only one version). BTW, after flashing TWRP I also though I can enter it with Vol+ & Power but that leads in my case to also a seemingly dead phone with not even the chance to power it down, no matter how long I press that power button (have 2.8.8.0 TWRP). My only reliable way to enter TWRP is to boot into the standard bootloader and from there to reboot 'custom recovery'. Anyway ... on topic :
@TO: while the phone is showing that HTC-logo and is 'dead' for any buttons, is it still listening to the USB-port? I could reboot mine with 'fastboot' (or was it 'adb'). Something like 'fastboot reboot recovery' (or 'adb reboot recovery') helped to get me out of that dead lock. Did you try that?
P.S.: Did I mention how much I miss my removable battery (though, the A9 is beauty because of that built-in battery!)? But actually I don't understand, why that 'universal' 10+ sec. power-button press doesn't switch off the phone! Normally this trick (also on PCs) works with a kind of software independent hardware timer ... well because, to work also in the worst case of software failure. No idea what HTC did there (the A9 is my first HTC).
Try to flash a RUU related to your phone, it should fix it
You have to Press both Volume Buttons and the Powerbutton at the same time for ten Seconds. This have worked for me every Time.

Huawei p9 lite [Your device has been...etc.]

SOLVED already!
Hello everyone,
i'm new to this so excuse if i do wrong something (title etc..).
I wanted to root my Huawei vns-l31 so i used the srk tool for enable the bootloader and then install the twrp; it seemed that all go right but when i tried to reboot in recovery mode i probably did something wrong in the timing with the combination of buttons and now the phone is stucked on the blackscreen with the message "your device has been unlocked etc etc.. your device is rebooting now.." the problem is that the device it's not really rebooting. I've tried the pwr for 10s, vol up+pwr, vol down+pwr but nothing..the phone doesn't go on fastboot and so i can't flash back anything. Pls help me i've read many threads on xda but no one worked for me.
again sorry if i broke some rules and for my bad english
Thanks to all that will answer this post.
Edit:i Just let the phone turno off because of the battere and then in reboot It showed me the three usual options..Maybe It was Just a bug. Still i dont know why It doesn't open the twrp..I'm Just bad at timing?

Redmi note 9 softbricked

Hello, i do not know where to post this but i really need help solving this issue.
I was installing twrp on my Redmi note 9 (merlin) and once the set up was done my phone rebooted to twrp, but it took time (a lot of time).
And i could not resist the urge of pressing the power button to restart it, problem is miui was not starting and it was stuck at the boot logo, i figured out it was a great idea to press the power button again, but it booted up on twrp, wich worked but the screen seem to be frozen and doesn't register any tap on the screen or anything, and now each time i press the power button no matter how, it either boots on my broken twrp recovery, or boots on my absolutely destroyed os.
PS: No matter how hard i try it seem to be impossible for me to access fastboot too...

I was able to get this issue fixed by :
1 Installing adb
2 Opening cmd inside adb folder
3 Entering "adb devices" while the device was connected
4 Then entering "adb reboot bootloader" while the device was still connected
5 Once the device was in bootloader mode i installed miFlash and downloaded this rom : mifirm.net/download/4163
5.1 If you have an error with the drivers, create a folder named log inside of the said miFlash folder
5.2 Also make sure that the path to the rom is not too long (i heard that miFlash had problems handeling long paths)
6 Once everything was set up i just hit flash and flashed the rom onto the phone
7. You're done ! You successfully repaired your phone and saved him from the depth of hell!
If you have any problems or need precision on certain points make sure to ask me in this thread so that other people can get help too.
i had flashed k20pros dtbo img file by mistake and my phone is not even turning on and no fastboot no recovery what to do please help!!!
