Going back to stock - Redmi K20 Pro / Xiaomi Mi 9T Pro Questions & Answe

Hey, i want to return my phone to the stock xiaomi android.
anyone knows how to do that?
currently im on latest evolutionX.
thanks

Was about to ask the same... I think you just need to flash the stock rom, if you are on f2fs you will have to format and change partition type, as stock kernel doesn't have the drivers for it

[Q] Wifi problem

Hello! I just bought this phone today and I've just managed to unlock the bootloader and install my first rom. However my wifi has been acting very weird. It works when using stock kernel and stock rom but hasn't worked on a single custom rom. I've tried a lot of them as well such as "xenon" and "pac". What is wrong here?

I'm a new user aswell, but I used other phones b4 and I recommend you to factory reset before Installing these roms (If they are not installed over stock rom), if you install them over stock ROM(which means the zip file DOESN'T format your /system partition) you should consider a factory reset after installation.
Before trying these, if ROM developer told you to use a specific kernel, try to flash that kernel back, I had some problems while installing some kernels and could never get my Wifi to work until I reflashed the kernel.
Take a nandroid backup to your external sd card before trying these, better safe then sorry
Maybe e reflash using the lastest original kdz firmware and going to alll the root - > CMW(now is oficial) - > install custom room should be the way.

Is this ALL Wi-Fi connections, or just a particular one that you are having trouble with? Is the Router set to use WEP? If so then you're out of luck as WEP has big problems, but as it is old technology you shouldn't really be using it anyway.

[Q] I cant install CyanogenMod on my LG G2. Any more ways to install it?

I am unable to install Cyanogenmod. I have TWRP that was installed with AutoRec. I tried flashing the Stable 10.2 CM version,and when I flashed it said "Failed", which put me into a security error boot loop. Then I tried a nightly, and it said "Success" and when I tried to start it up, it put me into another boot loop. I have the stock Kernel, and I am rooted. Is something like goo manager or rom manager better to use for this? Or what is the safest way to install a custom ROM

What he said, the official nighties only work with the JB baseband.
So is there any other way to do this? I saw that is is extremely risky, and it will permanently brick my phone. Is there any other thing im able to do to flash this?

If you want CM11 with the KK baseband(24A), use the version z3pp3lin pointed you to, otherwise most other AOSP based roms have already been upgraded to work with the KK baseband, use one of those. Just double check the notes on the rom to make sure it's KK/24A based.
Do I have to do all of those steps? You said there is a like for cyanogenmod for 24a. I don't see one though

All those steps are required to manually install a recovery on KK, that was pre-autorec, if you've already installed TWRP, you can skip to step 11.

You have the 24A KK baseband on your phone, you can only use roms that work with that baseband. If you specifically want CM11, you need to use the rom linked, otherwise any other 24A KK based rom will work. Check the notes for any rom you want to install to see what baseband it works with.

So If I want cm, I have to use his links correct? I just want to be sure so I don't get another bootloop
Why not just use a AOSP or CM based ROM that works with the 24A baseband... CM is good, but hardly the "best" ROM out there, if there is such a thing... Try AICP 6.0, it is extremely stable and the VS980 version is excellent and very feature packed.

Not too freak you out more, but no, there is no guarantee. That's why every ROM has the disclaimer in the OP. By flashing you're taking responsibility that you understand the risks involved. If you flash cm and damage your phone somehow, it's on you. So it's either stay with rooted stock where you know nothing will happen, or flashing and taking the risk. Your choice...

Nexus 6, probably a messup. Help needed.

Alright, I'm in need of some help, and I'm not sure if this is the right place to put this thread, so if it';s in the wrong place, I'm sorry for taking up space in the wrong section.
My issue is with my Nexus 6, the Verizon variant; I had a custom kernal, running 6.0, and was rooted. I wanted to upgrade to 6.0.1, and downloaded the newer version of the ElementalX kernal, the one I was using, as well as the necessary SuperSU files. I downloaded the new Android version, installed it, and before it went intoi the OS, I flashed the kernal and SuperSU upgrade, and now my phone either won't boot, or is taking the longest time for a phone to boot on the planet.
I need to download a 6.0.1 ROM that I can flash with TWRP. Any links or advice anyone could offer would be grately appreciated, because right now, I'm drawing a massive blank.
Many thanks!
Do you need to backup any data?
Could you not just flash a stock "like" rom such as this one by Danvdh http://forum.xda-developers.com/nexus-6/development/rom-5-1lightromstock-lmy47e-03-19-2015-t3059493 as it has already been rooted.
I have been running it for a while, very solid and stable rom.
Which SuperSU did you install?
Reflash the rom youre using and then flash Super su (asuming its not a pre-rooted rom) BEFORE flashing elemental x. Other kernels work the other way around
Question?
Are you trying to run systemless root wit EX? If so did you click on yes when TWRP asked you to root your rom?
That would would cause the rom not to boot.

Don't flash anything else till you boot at least once.

I decided to download and flash a custom CM13 build, but it's a bit finicky, kinda to be expected with an early release, though. I'm using that ROM, for now. I'd still prefer getting something from the CM team, something that's supported and I can download upgrades to.

Pretty sure it was 2.61. I have a few versions of it on my phone, ready for flashing, but was careful, making sure I chose the right one.

I'm not great with this stuff. Sorry4Noobishness. I'm not sure what systemeless rooting is.. Originally, I just flashed SuperSU and EX onto the stock ROM I was using. Worked fine. When I decided to upgrade, I downloaded the 6.0.1 ROM, installed it, but didn't boot into the OS. I booted into TWRP, and flashed the new EX and SuperSU stuff. The phone didn't boot after that. It was just stuck on the Google boot animation of all the interacting circles.
I decided to use a custom ROM, a CM13 ROM, but it isn't supported, which is why I'm not looking for a CM13 ROM I can use, because, well, I'd kinda like to be able to upgrade when an upgrade comes out.
Flashing a nightly build from their site did the same thing. I flashed the ROM, then gapps, then SuperSU, and it gets stuck on the boot animation. I let it sit for about half an hour, then restored the custom build I was using. I'm not really sure what to do to get a REAL CM13 build on this thing.

Sounds to me like you dont have the correct bootloader. Which bootloader are you currently using? try flashing the newest bootloader and radio then flash your rom again. It should then boot up fingers crossed.

Alright, I decided to go with this ROM, but now I'm stuck with an issue: It won't let me install any apps. Minimalist gapps was used, so I'm not sure what's wrong. Should I just flash stock gapps and see how it goes?

Why did you flash gapps? It seems that this rom comes with gapps already.

Wouldn't let me use the Play Store. Nothing would install, and it's kinda pointless to have an internet-capable device if it can't connect to what's supposed to provide me with that internet connectivity (downloading Chrome, for example). Had to flash stock gapps, but it all seems to be working now.

Appreciate your help on my LG G4 H811

Hi, guys:
I really need some help to make my LG G4 H811 work.
I flashed latest lineage-14.1-20170404-nightly-h811-signed.zip but my camera app "Keeps Stop Working". I tried other camera apps, none of them work.
I also flashed cm-13.0-20161010-NIGHTLY-h811.zip, same problem
I even flashed stock (but rooted) ROM, LG-G4-H811-20R-Stock-Debloated-Rooted, still the same problem.
I am using twrp-3.0.3-0-h811.img (the latest version for H811) and flash my phonh using ROMs from SD card.
Before I flash anything, the camera worked fine out of box.
Should I bring back stock ROM with LGUP/KDZ? However, I really need some 3rd party ROM working because I need multiple-user feature which is disabled in Stock ROM.
Any suggestion is very much appreciated.

thank you for the kindly reply. The issue has been solved by flash Stock 20p KDZ first in download mode then flash the same LineageOS through TWRP. Not sure which step really fixed the issue though.
I do have issues of video recording for 4K and 1080p, which is OK to me for now.

Question Debloated stock firmware/rom

Does anyone know of a stock miui rom for the Spes that has been debloated of ads and other crap and optimised? Don't mind whether it is a recovery rom or needs to be flashed with fastboot (or miflash).
I'm currently on v13 Android 11 the global version, quite happy to remain on that.
Can someone provide a link to the rom?
Thanks.
Look here: https://xiaomi.eu/community/threads/miui-13-stable-release.64441/
I have tested a lot of roms, and in the end I installed the official one and removed software through adb, today I don't have any bugs or strange problems, besides that I can use the camera in its entirety. I got bored with the custom ones, some games don't run, others are terrible and at the moment there is no fix for this.

Ditto, I always appreciate the custom roms and appreciate the efforts developers go to because there are a lot on here that do nothing but complain about custom roms, however I think I'd prefer a stable daily driver. There is no sign of the kernel source being released which would be a big help for the devs.
I've just finished flashing the stock rom and will go about debloating. There are a number of "safe to remove" lists for miui roms so I will get to work.
Thanks the replies guys.

Hi, may I ask how did you flashed stock ROM? I recently tried to flash 13.0.5 A12 on mine through TWRP, it probably refuses to boot because after the ROM has finished flashing I flashed TWRP next. I also know the fastboot + miflash method but everytime I do it, it gives me anti rollback check error
I downloaded the miui.eu rom which is debloated and allegedly more optimised. I went back A11 the same as I had before I unlocked my bootloader. I flashed the fastboot version and used the bat script inside the zip to flash it.

Ok, that's strange, it shouldn't give an antirollback error when you have the same version of android and miui.
Try again with myflash
But surely when flashing the official rom by twrp you damaged something, if I remember correctly the twrp of spes does not have support for flashing a stock rom, even less if it goes as an update.
Anyway, if you want to make your rom boot, try taking the boot.img out of the fastboot rom and flashing that boot.img to your phone and see if it boots.

My first guess was that it was because at that time I was on an Android 13-based custom ROM (Pixel Experience Plus 13 and CrDroid 9.0), but I was proven wrong after I flashed PE+12 shortly before trying MiFlash. Because it gave me the same error (Anti-rollback check)
Oh, I actually tried the flash-stock-ROM-via-TWRP method after I tried MiFlash method, so I doubt that's the issue. But all I can say is a few days ago I flashed 13.0.5 A12 firmware (latest at the time of writing), so could that be that issue?
I might wanna try what you said, thanks for the suggestion. But for now, I'm on EU and may stay for a few months

Always that I need as a base a stock ROM flashed, I "simply" use the fastboot commands that are inside the ROM, I open my ADB/fastboot CMD/terminal, and drag and drop the flash_all.bat file while in Windows or the flash_all.sh file while on Linux. This method allows to me, to can follow the process while the scripts are running, and search for issues (if there are some)
As per the TWRP flashing the stock ROM, it worked fine too. You just need to flash the ROM, then boot to recovery once, you'll find the stock one, then format data from it, then you are ready, either to go straight to system, or if you prefer have TWRP (or any custom recovery), go to fastboot and follow the method to boot to, and then flash it permanently to the ramdisk.
