If it worked before custom ROM, best to restore stock firmware and test your touchscreen.

I have same problem with the touchscreen and fixed with official N Rom.
Did you try flash another custom rom again? Is it still happen?

Same problem here.
Booted TWRP 3.2.3 off twrp site via fastboot boot twrp.img, phone got stuck, after poweroff-poweron touch sensor calibration was off.
Flashed original firmware, relocked - no go.
It's also hosed in TWRP, so not a firmware bug.
Can someone with a working Mi A1 dump all their partitions from twrp (adb pull /dev/block/bootdevice/by-name) and share privately as i hope touch sensor calibration data was stored somewhere and was damaged by the twrp?

I got the dump from someone with working TS and it didn't help on my device.
From dmesg in twrp I've noticed that my TS firmware was 0x0a version while working device shows 0x10, flashing stock tissot_images_7.12.19_20171219.0000.00_7.1_d39fa89 aaf.tgz helped in the end and TS fw got upgraded to 0x0a as shown in my dmesg after first boot.
Now I'm going to restore my emmc dump (to restore my imei and MACs) and will try to reflash this again.

Solved by installing an old version of stock miui through mi flash tool. Old as in android 7, not 8, be careful to check version when downloading from miui site.

[Q][L5 II] [E460] Fix touchscreen after bad flash

Hello, my friend tried to flash his E460 because his firmware was SIM locked but he used a wrong firmware and now the touchscreen and the 3 buttons on the bottom don't work.
I used LGMobile Support Tool and did an upgrade recovery, but the touchscreen still doesn't work.
Anyone have any solution? Thanks.

you will be able to use kdz updater in attached link LG-RDTT_1.0.5.4 (needs included windows enabler for this version)
use THIS GUIDE to flash just skip the hosts file editing steps

did buttons start working ?
did you flash kernel and/or recovery onto phone before ? <<<---that might have damaged hardware
did you open your phone at any time ?

My friend tried to flash it and he used a wrong firmware for E455 instead of E460.
I don't think he did anything else because it doesn't have a custom recovery installed.
The buttons and touchscreen still don't work.
I think somehow the wrong firmware installed incorrect drivers for the touchscreen or something, but I thought the drivers are stored inside the ROM?
burn it

You probably need to burn it with 10.000V or sell it and give 5 euros to buy new one. :good:

You shouldn't do that at the early release of the phone. Even any phone. You need to wait for the official rom release. How about you try fastboot and flash the twrp/cwm recovery. From the recovery use sideload to reflash the stock rom. Keep in mind that you should wait for a review or someone who actually successfully flash the custom roms/non-official rom. Except root, theres a number of successful root.

I know but i was desperate to get Google to work... Bricked or Chines system is same same for me...
Fastboot and TWRP cant find any device. Factory reset or wipe did not help either. Can access boot menu and Lenovo recovery, but need a recovery file first, and then we have problem with that i cant access the phones internal storage.... And this crap has no SD-memory either...
$700 down the drain for sure... Still have to buy a new phone though, and im still in China... Have to fly to HK to get a new phone... This is going to be expensive.
Thats what happen when you flash the unofficial rom. You know the risk. Make sure you have installed fastboot driver and adb driver. Im sure you can reflash the rom after you able to enter fastboot

[Q] screen wrong calibrated. HELP

Hi guys,
today i flashed the emotion kernel on my cm12.1 n910f, cause i thougt it'd work.
After this step my phone did not boot anymore. I flashed cm12.1 again, boots as usual but my screen is wrong calibrated. I press on the screen and the note thinks i press about one inch down and a little right.
I really tried everything to solve this problem. I had to factory reset because i could not draw my lock pattern anymore.
After that I flashed the stock rom, updated stock rom, reinstalled twrp, wiped everything, flashed cm12.1 again, flashed another kernel, flashed stock rom again.
The s-pen doesnt work anymore, not even on stock rom.
Could anyone please help me?
Thanks a lot!!
First thing you're gonna want to do is ODIN flash your factory base, reboot and test your screen calibration and S-pen now. Report back.
If it works now, you can start over and flash TWRP, and put a rom on it..

Make sure you flashed the full ODIN package and not just firmware... If you flashed the full ODIN package and it's still doing the same, seems you would have a defective device..

After installing RR, restore the original firmware of Xiaomi Mi A1, the problem is that no longer stable wifi connection, find networks but do not connect, try everything and there is no way to connect to a Wi-Fi network.
There is someone who has happened to him this before.

I imagine that soon they will solve it, since the same thing is happening to many of them, what you can do for now is to install RR once again, since Wi-Fi works there.

Please share the procedure, how to flash persist.img
Well, just find persist.img in the stock file like C:\Users\memo\Desktop\tissot_images_V9.5.9.0.ODHMIFA_8.0\images
then turn off your phone and enter into fastboot mode (down volume + power)
connect the phone to pc
the search for cmd
write : fastboot devices and if it shows number it means that is connect
then write: fastboot oem unlock (to unlock bootloader)
fastboot flash persist and grab the file and push it to the cmd
it should be end like this: C:\Users\memo>fastboot flash persist C:\Users\memo\Desktop\tissot_images_V9.5.9.0.ODHMIFA_8.0\images\persist.img

Mi A1 Wifi Issue after flashing stock ROM

Greetings!
I have been using Resurrection Remix for about a month now, but when the stock April patch came, I decided to return to stock firmware. I downloaded the most recent flash package from the official Xiaomi site and flashed it via MiFlash. When the phone booted up, I could see every wireless network, but when I chose to connect to any of them, the signal dropped a bit and it said "Connecting..." then immediately "Saved". After a few automatic try, it would just say "Disabled". The router settings are just fine, the phone could connect to it before I flashed stock rom. I also tried to download a bit older patch (9.5.4), which was neither good. After it I tried Nougat, but it still won't connect to the network. The hardware must be fine, since it was working an hour ago with Resurrection Remix. Could anyone help me out? Thank you in advance!
EDIT: Solved. The problem was with the persist partition, which is not flashed during the firmware flash process, so you have to flash it separately in TWRP. You'll have to download THIS FILE (persist.img), move it to /sdcard of your device, then boot to TWRP (you don't have to flash TWRP, only boot in it), tap on "Advanced" -> "Terminal", then type in the following: "dd if=/sdcard/persist.img of=/dev/block/mmcblk0p27". After it, reboot the phone into fastboot mode, and flash the firmware again. That's all.

Just flash persist.img if you only have the WiFi-issue.

Here is solution: : How to restore IMEI permanently after using factory flash
I have the same problem with IMEI, the fix is permanent.
After the repair can be uploaded any rom, including Oreo .
I also twisted up my IMEI. When I tried to downgrade to 7.8.23 it was boot looping. I was trying to solve it for 6 straight hours. Eventually, somehow the phone became unable to boot into fastboot (or anything else) for no reason. (a random shutdown occured during fastboot mode while no command was given). I had to turn to the Xiaomi service, since nothing could be done with the phone. Guess I'll have to use my old nokia flip mobile for 2-3 weeks.

Sorry I cant posting outside links,
You can try EDL mode:
solution how boot EDL mode via ADB or fastboot: link>> 99mediasector.com/edl-mode-boot-edl-mode-xiaomi-devices​I think this will not work for you​But you can try EDL:​via Deep Flash Cable (how quickly make Deep Flash Cable): link>> en.miui.com/thread-310325-1-1.html​or​via disassembly Mi A1 (Guide to Flash Bricked Mi A1): link>> en.miui.com/thread-1680467-1-1.html​

Greetings!
I have been using Resurrection Remix for about a month now, but when the stock April patch came, I decided to return to stock firmware. I downloaded the most recent flash package from the official Xiaomi site and flashed it via MiFlash. When the phone booted up, I could see every wireless network, but when I chose to connect to any of them, the signal dropped a bit and it said "Connecting..." then immediately "Saved". After a few automatic try, it would just say "Disabled". The router settings are just fine, the phone could connect to it before I flashed stock rom. I also tried to download a bit older patch (9.5.4), which was neither good. After it I tried Nougat, but it still won't connect to the network. The hardware must be fine, since it was working an hour ago with Resurrection Remix. Could anyone help me out? Thank you in advance!
EDIT: Solved. The problem was with the persist partition, which is not flashed during the firmware flash process, so you have to flash it separately in TWRP. You'll have to download THIS FILE (persist.img), move it to /sdcard of your device, then boot to TWRP (you don't have to flash TWRP, only boot in it), tap on "Advanced" -> "Terminal", then type in the following: "dd if=/sdcard/persist.img of=/dev/block/mmcblk0p27". After it, reboot the phone into fastboot mode, and flash the firmware again. That's all.

Now that my wifi issue is solved, can I delete the persist.img from my device? Please advice.
Mods please edit the op with a warning not to flash someone else's persist partition, this can permanently damage your chances of recovering your OEM Mac address and other sensors data, there's already a better solution out the called "persist resurrector" on XDA. !!!!DO NOT USE THIS!!!

Edit: But you need to have you original persist file
Thank you so much, Bro. You saved my day. I am getting the similar problem. And ended up flashing multiple ROMs. but nothing worked out until I found your post.
i used this tool to solve wifi issue.
while using this tool make sure you enable USB debugging or it won't work.
