[SOLVED] Touch not working at all - Xiaomi Mi 8 Questions & Answers

Hi here!
I bought my Mi 8 some days ago (China version, since I live there), and yesterday I finally got time to work on it to move to Global or EU_multi.
After some minor trouble (bootloop after installing magisk), the touch screen now is not working anymore: wherever I touch it, no response, both in recovery (TWRP) and normal system boot. Everything else is working, I can flash ROM via fastboot, and the ROM (I tried official China and Global) are correctly booting, but then I should touch the screen to complete the first time boot and I'm blocked, because it is not responding to touches. All other buttons are working (I can turn off/on the screen with power button, and I can hear the related sound). I can boot to recovery and fastboot. Everything seems OK, except the touch itself.
Is it possible that I did something wrong while trying to flash magisk? or disabling dm-verity and forced encryption? or anything else that could have caused this issue?
I tried to flash different TWRP recovery and different official ROMs (China and Global), but no result, touch always not responding...
If anybody have suggestion, please say.
And thanks in advance!

How about going to the thread about 'non-functional touchscreen solution'. It will fix your exact problem. No need for a new thread, you should have searched first.

new twrp's won't work
Hi there,
I just tried to root my htc mini 2 with and it says that it is tampered now and I can't reboot my recovery. So I tried the newest twrp and some in between because I've read in this forum that somebody had the same problem and he just got the newest twrp but that didn't work for me at all.
Is there any way to undo the whole thing by replacing the twrp with the original one or do I have to wait till there is gonna be a root for the htc mini 2?
When I try to recover everything it says that this build is for development purpose only...
Does somebody have an idea?
I would appreciate it a lot if somebody has an idea.

When the bootloader says "tempered" means that it was unlocked. when you see " this build is for development purpose only" its referring to TWRP because you now using a custom recovery. Not sure the nature of your problem but to undo, simply boot into boot loader and flash original recovery.img you can find in the forum.
I can't you open TWRP?

Thank you for the quick respond and I wanted to try and undo everything but no my problem is that my phone completely froze in the twrp screen. I can't do anything, I can't unlock it nor shut down my phone or start the bootloader... that kind of sucks. Any suggestions now? Is it possible to open the htc one mini 2 and take out the battery? or do I have to wait till it runs out by it self and than start it again?

Unresponsive after boot up from dead battery
THanks to U-ra I get the enjoy my fav DSP Viper!!!
Cheers Man,
I have a small niggling problem that I can't work out, My battery tends to die alot, once I place the phone on charge after a flat battery, the phone auto boots to Twp, I am really cool with that but the annoying thing is buttons and screen are unresponsive? I can't do a thing, just have the Twp menu. The power of button does turn the screen off/on but thats its. Tried doing factory resets, reboots holding down power, vol buttons. Just nothing.
only way around it is to use adb and reboot command.
Is anyone else experiencing this problem.

@u-ra is there any clue about getting official twrp support? (I was thinking about that problem of the self-booting recovery when phone is off and plugged in)

Help: Stock rom updated between boots, TWRP non responsive, fastboot doesnt recognise
Hello to anyone that can help or in a similar situation,
Have brand new HTC one mini 2, rooted. Am trying to install cyanogenmod and followed the instructions on their page. All went well and was ready to flash the rom from TWRP. Decided to do a backup to SD first and then apply super user. Forced to reboot and accidentally let it boot to android (stock rom). Didnt notice the last time i had it booted wifi downloaded a system update which was automatically applied next time i booted into the stock rom after backup and Superuser in TWRP. Rebooted to recovery (TWRP) as soon as i could, but TWRP is no longer responding to touch. I realise i have probably updated the phone to a point where TWRP is no longer working, and i have to use something else to flash my rom. Am trying to flash an updated TWRP or Clockworkmod recovery, but fastboot/adb no longer recognise the device when booted into the stock rom, and when i boot into TWRP (non-responsive) it also doesnt recognise the device attached, even if i catch it before the screen goes black from inactivity. Any suggestions greatly appreciated....

A kind member replied to me in another post indicating that fastboot commands only work in the bootloader, and that adb commands only work in TWRP which is why I am having problems re-flashing TWRP (requiring the "fastboot flash recovery TWRP.img" command). However I thought TWRP replaced the bootloader, so I seem to be locked out of re-flashing TWRP because i have TWRP. This seems not to make a lot of sense, can anyone else confirm or otherwise explain what I have misunderstood about that? As stated neither adb nor fastboot recognises the device is attached to the computer any more, so commands are not executing...

I think I have found the solution for myself: I went back into the stock rom and did a factory reset (from within android booted up as normal), which after completion rebooted me into TWRP which now works fine (is responding to touch again, and i can flash the Cyanogen image now). Hopefully this helps someone else in this situation one day, or maybe I am the only idiot that needed to ask hehe. I should clarify that after flashing TWRP I lost access to the fastboot screen and could not push anything over ADB or fastboot commands from windows (plugged in via USB). Holding down volume down and power booted directly into TWRP, and i had no way to get to fastboot screen. After doing factory resent from within the Android OS, holding volume down and power booted me to the fastboot screen, and only when I selected "Recovery" did it take me to TWRP, and I was again able to run fastboot and ADB commands from PC. Weird (or maybe not if you know more than me), but there it is...

Sorry, but it seems to me that you don't know the difference between bootloader and recovery. I apologize if you do. If not, search in CM wikis or ask here for explanations.

I do indeed know the difference between the bootloader and recovery, its just that the bootloader (Hboot) was not longer accessible in my situation and TWRP (the recovery) was imposing itself when you would normally expect to find the bootloader (i.e. my bootloader was for all intents and purposes replaced by my recovery, while I am sure this is not true in fact, it was in effect). As I say, doing a factory reset from within the OS restored the bootloader (HBoot) and I was able to continue modding. I am today extremely happy with my fully secured cyanogenmodded HTC One Mini 2 via TWRP recovery method. I hope that is somewhat clearer.
Can you enter bootliader now? I got stuck in a bootloop once and couldn't enter bootloader because I continued pressing power and Volume down like I did on my One S. For Mini 2, we have to hold the Volume UP and Power buttons until HBOOT appears, then release the buttons.

That may well have been an alternative solution to my problem, however it was fixed by the factory reset and volume down and power then took me to HBoot (this would appear to contradict what you have said above, but maybe volume down and power does different things depending on how what you have done to the phone, not sure), so I cannot confirm whether or not that also would have worked for me. Good suggestion though, especially if you are not in a position to do a factory reset. and it would certainly be easier if it worked...I am convinced my problem was the result of a conflict between the TWRP version i installed (downloaded from here) and the android update that occurred between boots.
I am indeed able to get into bootloader/hboot and successfully flashed cyanogenmod from TWRP. I can confirm post flashing TWRP and Cyanogenmod, holding volume down and power takes me to HBoot (and then the option to go to fastboot or recovery).
Holding power up and power just loads cyanogenmod for me now as if I had just pressed power.
I thought I should confirm whether or not holding volume up vs volume down with power results in bootloader vs recovery loading. For me, they both took me to TWRP.
Also, TWRP doesnt seem to work on HTC One Mini 2 after you do anything to set up your phone. It just doesnt recognise touch input any more so you cant do anything with it. However the fix i noted earlier (factory reset) even works with other roms installed, confirmed for cyanogenmod 11 and 12 nightlies as at the date of this post. After factory reset TWRP works again, but if you go through the setup steps and start installing apps, TWRP goes unresponsive again. I hope we might get an official TWRP update soon!

Bricked after installing twrp, any ideas?

Hey, was just setting up my mi5 for custom roms. Got the bootloader unlocked, then installed TWRP via fastboot as per the instructions here (https://twrp.me/devices/xiaomimi5.html).
After I got into TWRP I made a quick backup of the image, and then set the phone to reboot. Now its in a bootloop, flashing the mi logo (and bootloader unlock on the bottom). Doesn't turn off, doesn't do anything when plugged into pc, fastboot reboot doesn't do anything.
Any ideas? Didn't think I had done anything wrong (done this kind of thing a couple times before).
Cheers!
EDIT: Hang on, managed to get into fastboot, I guess I should be able to sort things out from there? What should I aim to do. I can also get into recovery. Still won't boot into system anymore though.

Which twrp version are you using?
Did you actually flash any custom rom or do you try to start miui?
Did you change any partition?
Something similar happened to me one time. I solved it by doing the root right after installing the twrp. And magically started my rom.

Rog phone 2 stuck on a bootloop without ever trying to install a custom rom

I have my rog 2 stuck in a bootloop. I don't really know why in the first place, because I don't like to change and mess around with custom roms. So i've never done that.
The case was that I was watching a video on YouTube and suddenly the touch screen stopped responding, the phone kept responding to other inputs such as the power button and the volume rocker. So I decided to restart the phone. And then it didn't turn on again. Got stuck in a boot loop.
I've been trying to fix it for a long time. But I just can't do it. Nor am I able to see what is happening with the phone. I have used this guide.
EVERYTHING works perfectly, it doesn't give me any errors during flashing or anything like that. Even the program tells me that the rom has been flashed correctly, and even the rog logo during boot, changes (I suppose because it is a version of the rom prior to the one I had.). The fact is that even with that the phone is still stuck in the bootloop. I have tried more things but this is the one that has taken me the furthest. I don't know what else to try. If anyone has any ideas, please tell me.
P.D. Sorry if my English is a bit rusty.

Any suggestions which rom I can use? I have tried the rom of the guide and the ones that Asus has on their website. None of them have bailed me out.
@Arnau17 Any Updates? I am facing the same issue. Mine reaches till boot logo and then freezes and reboots again. Tried flashing stock ROM as well but no Luck
I am in the same situation, tried several raw rom files, still in bootloop
USB plug correctly on side USB port? can you enter recovery or fastboot mode?
i have same problems before, if fixed after flash RAW rom, hope this help.
is there a guide to fix AVB VERIFY FAIL on Rog Phone 2

[Question] Pixel Experience 12+ on my Redmi 9 is rebooting on lock screen.

Hello, it's my first post on this forum so sorry If I made this thread in the wrong place.
I have been trying to install PE 12 (plus edition) using official PE site (https://download.pixelexperience.org/lava).
After many attempts to do so, I ended up installing different TWRP recovery images and wiping everything from my phone.
Then I've tried installing official recovery image from site and I've installed ROM by adb sideload and it worked.
First boot wasn't a problem, but from start phone would sometimes crash when attempting to turn it on (or, attempting to unlock lock screen. I can write my PIN, but then rebooting happens). When it wouldn't crash (it's not happening every time) everything would be working as long as I don't turn it off. I don't know what is causing that behaviour.
Would reinstallation help or is it hardware problem (not enough RAM etc.), or lack of swap partition?
PS: Updating every app on phone doesn't help, as well as removing lock screen (no PIN etc.).
Update: I have installed different ROM from sourceforge dedicated to my phone version (galahad). It is android 11. Works 100% fine.

touch screen doesn't work with twrp (or pitchblack)

I have a Redmi 9c on which I try to install a new rom like many tutorials suggest
So once I switch to bootloader, I run fastboot reboot recovery I get to twrp (3.5.2) but my touch screen doesn't work, I can't do anything.
do you have an idea of the problem ?
(in doubt I tried with PitchBlack but I had the same problem, when it turns itself off, I can't even swipe to unlock it ^^)
I think I forgot something or did something wrong but I don't know what, and I can't boot on the original rom anymore, at best I have the fastboot

Hi, I think the issue is that twrp and PitchBlack is not compatible for your device. I don't think the error is in your phone, but in those costum revovers.
I tried to put back a stock rom because even with orangefox it didn't work, exactly the same problem.
but i must have done something wrong because the phone doesn't answer anymore, it's always trying to reboot and when i plug it in the pc, it's not visible on the usb.
✝✝ it's the end. ✝✝
we'll all go through it one day, and for the redmi its done.
thank you for reading my sad story^^
