I had vibration working on PE Slim, maybe it's the way how we install it? I flashed so much, I can't still remember how I have done this
[Xiaomi 11T Pro] MrScarl3t:
vibration is a vendor problem, depends on what version of miui u used as a base. 12.5 does the auto brightness not work, and 13 the vibration doesn't work. im not a dev just a guy trying to find something better than miui.
[Xiaomi 11T Pro] Bojanum:
So if I downgrade to 12.5 as a base vibration will work? Is there any ROM with the 13 base that vibration works?
[Xiaomi 11T Pro] bariz143:

Does video playback work for you? Most apps crash with an out of memory error when playing a video.
[Xiaomi 11T Pro] Hash.IM:
Never happened to me on Lineage or Arrow!

Even I had a 4K Movie that I couldn't play on my laptop, It played on my phone just right.
[Xiaomi 11T Pro] Shubham1815:
are these GSIs stable??
[Xiaomi 11T Pro] RainGater:
I am planning to flash PE GSI. I am currently on 13.0.1. My steps:

adb reboot bootloader

fastboot reboot fastboot

fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img (extracted vbmeta from MIUI 13)

fastboot erase system

fastboot flash system PixelExperience_arm64-ab-12.1-20220322-UNOFFICIAL.img

fastboot reboot recovery
--- wipe data in Mi Recovery

reboot

I am NOT really sure why the OP and others ask you to reflash the stock ROM at the beginning when you are already on v13.0.1. Any ideas?
[Xiaomi 11T Pro] MrScarl3t:
clean flash makes sure that your a and b slot are correct sometimes things just get messed up this prevents other issues later on

So whats the best gsi for our beloved device?

Bluetooth, Sms and Haptic Feedback is a MUST WORK for me.
[Xiaomi 11T Pro] MrScarl3t:
Haptic Feedback is not working but if you wait till phh realease higher than >411 it will
[Xiaomi 11T Pro] bariz143:
Im good with Haptic not working for now. But bluetooth and Sms needs to work. Wich one would you recommend?

Never mind. Tried all the GSI images and non of them have sms working either.
[Xiaomi 11T Pro] RainGater:
What GSI's did you try?

What about crDroid-8.3-arm64_bgN-Unofficial.img? Did you try that?
[Xiaomi 11T Pro] bariz143:
Yes i did. Did not boot. Have you been able to boot it and does it work?
[Xiaomi 11T Pro] donjamal:
Texting works on ALL GSI, you just need to do this: ims features/install ims apk for qualcomm vendor - reboot.

And before doing so, tick the checkboxes on the same screen if texting does not work. I'm on T-Mobile HU and worked without any issues. Bluetooth audio is a no go for now but calls are working.
[Xiaomi 11T Pro] bariz143:
OMG you are a LIFE SAVER. Tried it many times but never thought of rebooting the device. Awesome man :D
[Xiaomi 11T Pro] RainGater:
Yes, crDroid does NOT boot as it gets stuck on Mi Recovery. Tried two times and no buenos!
[Xiaomi 11T Pro] MrScarl3t:
you need to go to phh settings > ims features > install ims apk this will make it work

i use Arcana 5.0 cuz the 5.1 has battery problems Waiting for dotos 6.0
[Xiaomi 11T Pro] pimpo154125:
i have the same issue and i don't know how to resize partitions anyone help?
[Xiaomi 11T Pro] Cubiss:
While resizing partitions is possible, it's really easy to hard brick your phone. I'm not gonna link any guide as I never tried doing it on phone.

I recommend using a different GSI (PixelExperience vndklite works great for me).
[Xiaomi 11T Pro] toniteixiera2007:
Can anyone tell me the difference between pixel experience and pixel experience plus? And whats the difference between normal, slim and vndklite?

Is 5G available in any of these roms?

120w fast charging working?

By your experience what's the more stable rom? Pixel experience, crdroid, aosp, etc?

Thanks
[Xiaomi 11T Pro] MrScarl3t:
5g no, 120w yes, slim is less then 3gb, vndklite/lite read write system.

difference between pixel experience and pixel experience plus not much just small customization things nothing major.

Pixel experience most stable but I like to use Arcana or Superior (Get them here) bit less battery life but much more customization options, mi 11t pro doesnt like the build from Nazim dont know why.
[Xiaomi 11T Pro] toniteixiera2007:
Thanks a lot! Tried to install the standard plus but got an error about partition space... So installed slim plus and it works very great! At first sound was horrible but went to phh settings and disable sound volume effect in qualcomm features and i resolved the sound problem except whatsapp calls... Super distortion...
[Xiaomi 11T Pro] mlgWOWmeme:
I also stick with the Pixel experience although it's the full version. I'd like to ask that Dolby Atmos is lacking and not found on Tidal or even the settings and the refresh rate settings. *Note: I installed a Dolby Atmos module for Magisk but it failed to work and caused me into a bootloop got to re-install the Pixel Experience.
[Xiaomi 11T Pro] money29:
I have manage to install multiple gsi and resolved every problem by reading comments.

But I have new problem now, I cant able to make calls from my JIO sim.

There is no VoLTE Options in pixel experience. Any solution for that?
[Xiaomi 11T Pro] djkrish5610:
Hey,

GSI rom with Magisk+root or without root.

Magisk root is being detected since April 2022 hence i switched back to stock .

Please let me know is root being detected in banking apps ?
[Xiaomi 11T Pro] FantaC4t:
Hey, After doing the first step in the second step i have this error: "C:\adb\fastboot.exe: unknown option -- disable-verity" anyone knows how to fix it?
[Xiaomi 11T Pro] mlgWOWmeme:
Did you use minimal adb? Use the one (latest version highest number) of this forum post. Adb tools have to be changed.
[Xiaomi 11T Pro] FantaC4t:
Yes I did use minimal ADB and did everything according to the tutorial, could it be because its the Xiaomi 11T and not the pro one?
[Xiaomi 11T Pro] FantaC4t:

Can you tell me if you have managed to solve this issue and how?

is there gsi rom selinux enforced?
[Xiaomi 11T Pro] morpheus620:
I managed to install PE with MIUI13 firmware.

At the beginning of the setup the vibration still works but after my account was restored it no longer works.
[Xiaomi 11T Pro] Sammmnh:
Ok guys , nice work here

I have the following questions if anyone like to answer :

1) I have some bank accounts that I need to hide , is there any hidden apps option , if yes , how to reach it after hiding , and dose it appears in the recently used apps menu ?

2) out of the many things that I hate the most in the official software is the speaker sound , the phone has strong hardware , but the sound is very low especially when making call in car or crowded place , or even watching videos , so is the speaker sound louder in this Rom ?

3) the only thing that I found good enough in the official software is the lock screen notification animations , and the good battery performance , I hope that it is the same in this rom , so is it ?
[Xiaomi 11T Pro] morpheus620:
I had some problems with GSI.

Auto brightness was not working properly.

No vibration for that. And the GCAM could not record videos in 4k.
[Xiaomi 11T Pro] Hash.IM:
For hiding apps I use Neo launcher (formerly known as Omega launcher) it has a feature to hide some apps from the app drawer. And IMO it's the best launcher you could find to replace nova launcher.

Speaker sound is good, I didn't actually used the stock rom so can't compare but after flashing LineageOS and applying the GSI tweaks mentioned in OP the speaker sound is pretty loud (Lacks bass I guess but loud).

Can't speak for stock rom animation, but for battery I get a massive 9 - 11 hrs SOT on LineageOS.
[Xiaomi 11T Pro] Cubiss:
I'm using PixelExperience GSI.

Does updater work for you? I have two issues with it.

1) It stops the update when I move the app to background or when screen turns off.

2) When I make it run till the end, it says "Switched slot. OTA finalized.", but after reboot I get to the old system.

I tried switching the slot manually via fastboot but that didn't let me even boot.

EDIT:

I can't update via fastboot either. And I can't even flash the old one, which is weird to me. Is this a common issue?

PS D:\Downloads\test> fastboot flash system_b .\old_slim.img

[Xiaomi 11T Pro] TheRomFan:
If you experiencing any issues with the GSI roms

You can check my post on how to fix most of these issues i.e (LTE, 5G, Audio, Whatsapp audio , Auto-Brightness etc..)

It took me along time of testing and erasing my phone multiple times!

[Xiaomi 11T Pro] TheRomFan:
Can you tell me what version of MIUI are you using for example V13.0.9.0.SKDEUXM
[Xiaomi 11T Pro] Cubiss:
You're using PixelExperience GSI, right? Can you update your ROM via Updater?

Great post btw.

How do i fix 5g ?
[Xiaomi 11T Pro] Edoardo001:
The op not mention nothing about bootloader or custom recovery. Do I need a custom recovery? Do I need to unlock bootloader?

Thanks in advance
[Xiaomi 11T Pro] Gabrielmonsa39:
Booloader unlocked required. No custom recovery is needed though.
[Xiaomi 11T Pro] Cubiss:
In "Settings/Phh Treble Settings/IMS features":

1) Install IMS Apk for qualcomm vendor (if you didn't do this yet)

2) Enable Request IMS newtork

3) Enable Force the presence of 4G Calling setting

In your Dialer app:

1) type *#*#4636#*#*

2) In testing menu open Phone Information

3) Set Prefered Network Type to anything including "NR" (NR = New Radio = 5G)
[Xiaomi 11T Pro] aldiandrew:
Hello sir great explanation since this phone doesn't have custom Rom yet can you list any gsi Rom that available right now, thanks sir
[Xiaomi 11T Pro] Cubiss:
There's a link to Github in the original post.

I'm personally using PixelExperience and aside of OTA updates it works great. I update manually via fastboot.
[Xiaomi 11T Pro] azizolmez:
For non pro?
[Xiaomi 11T Pro] Cubiss:
Xiaomi 11T Pro. But most GSIs should work on both.
[Xiaomi 11T Pro] aldiandrew:
Cool thanks for reply, I will try it on weekend, anyway for 11t pro it's works almost everything right? Because MIUI Rom it's so damn slow lol
[Xiaomi 11T Pro] Cubiss:
Most will work pretty well with fixes found in this post.

[Xiaomi 11T Pro] VicVance:
Hi guys, I also have the same problem, I can't boot any GSI custom ROMs on my 11T Pro.

I tried replacing "system" with "super" as the system partition doesn't seem to exist.

The ROM is flashed but when the device is restarted it automatically returns to FASTBOOT.

Solutions about it?

Thank you very much
[Xiaomi 11T Pro] TempestHunteye:
what GSI you use?
[Xiaomi 11T Pro] VicVance:
I've tried installing several.

Including the Pixel Experience, the Android 13 Google beta 2 and the squeak.

Each of these flashes to me only with the command "fastboot flash super namegsi.img" but then when I restart it automatically re-enters me in fastboot.
[Xiaomi 11T Pro] dantk:
what about battery sot without playing games ?? is still ugly like in miui ??
[Xiaomi 11T Pro] TempestHunteye:
fastboot flash system Gsi.img... that the command i use

Disable setup wizard on setting - apps - show system, and you can set fingerprint

Best way to make it work is patch your own boot.img

I've heard that ANXcamera isn't available
[Xiaomi 11T Pro] lythongac:
Thks your rep! Hope best choice for me, but do you try android 13 gsi gsm in list?
[Xiaomi 11T Pro] aldiandrew:
Camera works but not as best as miui, im using gcam for camera and video and yes its possible to ultrawide video record, and can switch it real time (i forgot miui cam can do it or not lol) anyway im using corvus os, and for your question about android 13, i think its still beta and cant be use to daily driver
[Xiaomi 11T Pro] Matty0201:
I didn't, I only tried Lineage before PixelExperience but it had some weird bugs preventing daily use. PixelExperience is a solid choice for stability and reliability. Only thing to mention is that sometimes I get some weird battery drains (still better than the miui) but apart from that it's all good
[Xiaomi 11T Pro] lythongac:
So I using Miui 13.0.6 so with above guide! Do I need run file flash_all.bat to flash rom stock 13? or just from this command

[Redmi Note 10] Vuxoni:
Hi,

The power button on my Redmi Note 10 has become too sensitive. It reacts to the slightest touch, I just put the case on it, they literally barely touch each other, and immediately the phone turns on or off. I had a problem with restarting tself, probably because the button is stuck. Does anyone know if the problem can be solved without changing the button, and what is the approximate price for the button?

My phone is out of warranty because camera glass and back cover are broken.
[Redmi Note 10] muneeb rizwan:
same thing happened to my volume down button

for me the solution was to press the button really hard until its sensitivity fixes itself
[Redmi Note 10] 11111aa:
Hello,

I just wanted to say thanks to this solution. It sounded ridiculous at first and then i tried it and it worked!!

So yeah thank you so much :)

Till it works
[Redmi Note 10] howitzer777:
Just 4-5 seconds
[Redmi Note 10] nuyuyui:
Wow, it's real!

Last night I encountered this type of oversensitive, but now my F3 works properly.

I tried 3,4 times of few seconds strong pressing with towel, depends on your phone.
[Redmi Note 10] Boxu:
Literally created this account to reply. Same phone. Same issue. I had lost hope and thought this won't work but just wow! My heart nearly sank when it happened and just like that it's fixed!

Sending Much love to everyone who contributed to this and my thanks!
[Redmi Note 10] troolie:
Those buttons are built as cheaply as possible. A springy steel dome that you squeeze over a coper pad to make contact. The two parts are held together with tape. Dirt or corrosion on the pad will make contact unreliable. Or it can also become weirdly sensitive if the dome slides out of position under the tape and can't spring back anymore.

Anyway, use software features as much as possible to wake or turn off the screen (double tap to wake/sleep, lift to wake, fingerprint reader...). Especially when you can't leave the damn thing alone and press the button 1000x a day.
[Redmi Note 10] ZetshkiYT:
Thanks man, you solved the problem I was looking for.
[Redmi Note 10] ..k..l..m..n..:
As weird as the solution may sound at first - it actually worked with my Redmi 9 as well, I stressed the button for some time, tapped here and there - and all went back to normal :) Thanks!!!

[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] ganapathyraman_s:
I am not clear about the following steps:

Install microG services core (F-Droid)

Install microG services framework proxy (F-Droid)

Can u kindly guide me on the exact files to be downloaded and how to install them?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Neurotical:
Yes the support for signature spoofing is enabled by default for you in this ROM.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Neurotical:
The first thing you need to do is install the F-Droid store from the official source: https://f-droid.org/

Then you need to add the microg repository in F-Droid per the official instruction: https://microg.org/fdroid.html

Then, you need to click on the links on your Note 9 with F-Droid installed, and those magnet links will open F-Droid and bring you to the proper package for installation.

Is microG services required and Is this done after you install the phone and restart it?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Neurotical:
MicroG is not required, but the ROM supports it if you want to install it.

If you want it, you need to install it after the ROM is installed.
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] jdennis61:
Thanks. Is baseband updating just for backing up your stock firmware in case you want to reinstall it?
[Samsung Galaxy Note 9 (Exynos) ROMs, Kernels, Reco] Neurotical:
Good question! Baseband updating is flashing new drivers (closed source from Samsung) for your cell phone modem. It usually results in better efficiency and signal status, but is not required.
