Hey guys, I am facing a weird problem.
I was running the January patch, rooted with magisk, but I was facing some problems so I decided to return to the December Oreo patch.
I flashed the official patch (xiaomi firmware site) and I did a clean flash but after I flashed it when my phone booted it wouldn'1 detect my sim card and it reboots every minute and it's unusable because it keeps rebooting.
I tried flashing the January patch again but the same problem remained and it wasn't fixed.
I tried returning to the Nougat but when I flash the official firmware image, my phone enters a bootloop and doesn't start.
I don't know what caused this problem but I need help.
Update: wifi doesn't work either.
Try to flash the .18 nougat build with miflash, if I remember right it maybe could fix your issue. Nothing to loose anyway and do a clean flash.
Flash persist.img from August build, I'm sure it'll work.

I had custom roms installed on my device but decided to go back to stock rom. I was able to restore the stock rom, updated and installed twrp and root on my device. I noticed that after I did this, my headphone jack stopped working and my PC doesn't detect my phone for USB file transfer or MTP configuration anymore (on stock, rooted). I wanted to know if I have the same problem on custom rom so I flashed a custom rom and both issues are resolved. Although I liked the Custom roms I tried (Havoc OS and Arrow OS Pie), I decided to go back to stock again this morning because one particular game that I'm playing (Mobile Legends) isn't working properly on custom roms (screen would sometimes flicker or go into black screen, I didn't experience this on stock). This time I decided to forget about root and relock my bootloader. After updating, I ran into the same problem with my headphone jack and usb file transfer. Does anyone have the same problem? If so, how did you get the headphone jack and usb file transfer to pc working again? Please help. Thanks.
I am facing the same problem ! anyhow installed lesser and switching between speakers and headphones ! Usb still isn't working !

The only way I could use usb file transfer is when I boot into a custom recovery. I went back custom rom for now, until I find a permanent solution for both. I tried searching for answers at the Zentak forums but couldn't any help there.
Have you tried flashing the raw firmware first than update? It's here somewhere on unofficial unlock/re-lock post, I went back to stock ROM after re-lock without any issues. I did have an issue flashing using AFT after re-lock, but flashing corresponding recovery.img than flash firmware using recovery solved that.

Hi! Thank you! My problem is now fixed, both headphone jack and USB file transfer, although I'm not really sure if it will work for others. What I did was I flashed (while device is unlocked) the Nougat raw firmware (WW_ZE552KL_14.2020.1712.85_M3.10.47.15), tested it and both were functioning. I decided to update to Oreo using the system update feature and it is still now working after I installed all the Oreo updates. I'm not planning to re-lock anytime soon as I installed root and found it beneficial.
I did follow the unofficial unlock/ re-lock prior to doing the previous steps, although I first flashed the factory raw rom (CSC_ZE552KL_13_13_1_36_M2_6_7_P7_userdebug.zip), unlocked and the flashed the Oreo raw firmware (WW_ZE552KL_15.0410.1806.68_M3.10.47.19) . Maybe skipping to flash the Nougat Raw firmware caused the problem? I'm not really sure, sorry I'm relatively new to all these.
Glad to know it's all ok on your part

Yup you should flash Oreo RAW as custom ROMs (Android 8 and above) needs latest modem.
HI guys please help me,, i upgraded to android pie via ota,, and my wifi was not working after updating and mac address was showing 02:00:00:00, so i decided to factory reset but it didn't help,
Then i downgraded to 8.1 nov rom, after that it keeps on bootlooping, flashed many times with clean and clean and lock, still not working.
i can go to fastboot mood , edl mode, bootloader unlocked,, please help me
I suggest clean flash last official rom on xiaomi site using Mi Flash tool.
I think this is the only correct return to the basic ROM
for more is your choice.
i have done that.. still in bootloop
https://forum.xda-developers.com/mi-a1/how-to/solution-bootloop-9-0-beta-t3876533
Try this solution
tried.. no luck bro
any help here? between i again flashed pie update through twrp, and its working again,,, but i am not able to downgrade and wifi still showing random address or 02:00:00:00 sometimes
Check for IMEI with *#06#
Is correct or not?
What Pie update did you flashed?
imei is correct , but wifi mac has changed
Have you fixed ?
I have the same issue
I had the same issue, bought mi a2 lol.
I finally give up. I had lineage 15.1 running on the device and decided to upgrade to a pie based rom. So I flashed november firmware, rom etc. then I only had 3g. Now I decided maybe I need to flash latest december firmware so I flashed the 10.0.3 firmware zip and lost my sim card completely. I reflashed the november firmware. This made the device bootloop so I decided to flash stock november rom again and start all over. Now it's independent of the rom it's running it boots until the sim pin dialog, i can even press some numbers but it just reboots after a certain amount of time. Access to fastboot works fine so any idea how I could fix this would be greatly appreciated.
Looks like you got a corrupted EFS partition. If you have a TWRP backup for that, just restore. And if you don't, there is a thread in the Mi A1 forum about restoring EFS when downgrade from Pie.

First of all try to disable SIM Pin Lock from another phone. It was a bug from previous releases.
Second: never downgrade from Pie because it will causes issues and potential corruption.

But is downgrading from a custom rom comparable? And the firmware zips only have modems and bootloaders don't they? I am always struck how difficult the a1 is compared to my pixel 2

Well, you upgraded to 10.0.3.0 so you must use only that Pie firmware for now
Hi Guys, hopefully someone will be kind enough to help me out here!
So I flashed my S7 Edge with Superman Rom a week or so ago and loved the Rom itself, however all I have got since is no signal, no imei, and won't read my sim. I've tried everything I can 're flashing Rom, trying to replace efs file (no backup as it got deleted ☹) and tbh I really haven't a clue what else to try.
I did try to refresh a stock nougat Rom through Odin but this now fails due to boot.img ?
So bloody lost.
If anyone has any ideas what to try I would be really greatful.
Cheers
Matt

Thank you mate! ...seems that the firmware I was flashing was not the newest version so couldn't update the boot to flash. Downloaded most recent Oreo and it flashed through dirty. Had to then flash TWRP and new root before installing would complete past the dreaded 'No Command' with yellow triangle screen! (Probably my fault for dirty flash - but just incase yours doesn't fully wipe if you get same problem as me). Rebooted and Oreo installed no probs and both my signal and IMEI have returned!
Custom ROM flashed and all still working no probs.
Much appreciated for the help!
