Today I got my new Xiaomi 3S (4G, 3GB RAM, 32GB ROM) played around with it a little bit and disabled all Google Apps to be found on the phone Except Google Services that couldn't be disabled.
Connected it via WLAN and got promptly OTA offered. I didn't wrote down the MIUI and Android builds but remember manufacturing date August 2016, MIUI was version 7 something.
After the updates where downloaded I was asked to reboot the device what I confirmed and the updates where installed. Now the phone is stuck with a black screen and white "MI Powered By Android" on it.
Nothing changed since 3 hours now. Any idea what to do?
Phone can't even be turned off/does not recognize hardware button presses.
This is a known issue, disabling google apps causes issues . You should now try following this guide http://en.miui.com/thread-327861-1-1.html

Thanks a lot for your reply, tried it already yesterday while the Phone was in endless boot queue without luck, hence the non working buttons update.
But today after the battery was emptied over night I got into the recovery mode menu!
Just a question before I go ahead to follow the step by step guide:
Though I read this thread/vote I'm non the smarter. If I want to go google free, Xiaomi Global or Xiaomi EU ROM?
I'd also use XPosed framework with XPrivacy again. IMUI seems nice, is CM 13 the only alternative for non google/XPosed/Xprivacy then?
I currently have a 3s prime but it's a present for my son so haven't flashed anything, just take ota's. I have read quite a bit though and you should maybe just check the rom threads for roms with separate gapps packages, that way you could remove what you want prior to flashing. Don't know about xposed but again, ask in the rom threads. [emoji106]
Update: No success, when going into recovery mode (pushing volume up and power button) and choose download mode the phone will just reboot into endless boot-loop.
For people with the same problem (after disabling google apps) maybe they can get their device back to work with this http://en.miui.com/thread-378963-1-1.html
The only Way to get you phone back is to use a Deep Flash Cable i think
I was able to solve the problem by installing a fastboot-rom. Pressing power button and volume + for around 20 seconds got me into recovery menu.
Than I was just following a guide to install an original MIUI rom on devices with locked bootloader.
well to get to download mode you can enter "fastboot oem edl" without the "" and you will go to edl from fastboot mode. HOPE THIS HELPS

Now I know why my phone went into a bootloop. Won't disable any Google apps anymore.
Disabling any apps in MIUI8 will cause the phone cannot reboot... you can format everything through a recovery (have to flash manually because it doesn't come with recovery), or flash a new ROM through fastboot mode (if you have unlocked your bootloader), or send back to service center to claim warranty (if there is any service center in your area), or throw it and buy a new one

I have same problem but in my case developer option is locked so oem is off and thus port COM10 is not being shown in Miflash, also fastboot oem edl says device is locked, oem edl is not allowed. In my case 3s prime went into bootloop while Iwas using youtube. Please help!!
Alright. just to get this out of the way, I used to do tech support for HTC many moons ago. like back when they were *the* name in originating new tech to smart phones. I worked my ass off to get into the R&D team that handled all the new products that got released and to our product recovery team(the idiots that try to put a good light on a bad decision made by corporate). I have rooted and installed custom ROMS and recovery software on several phones from them as well as since then with the latest being my old galaxy S7 loaded up with TWRP and lineagoe OS(although i do not remember which version now)
But i did not do literally *ANY* of that with my Xiaomi MiA1. the phone functioned how i wanted it to out of the box and with the stock ROM, i had no need or desire to do anything with the ROM.
I have all but completely given up on doing this on my own now. I have gone over every guide on the MI forums for xiaomi and i think i may have even exhausted the ones that are available here now too. I am not sure WTH the problem at this point even is but here is the lowdown:
:fingers-crossed:
got the update near the end of December/beginning of January to update my MI A1 to the new android pie version that just came out OTA(i actually have two of these phones, one i have not updated since the first update to oreo, and this one that is hardbricked from after the PIE update)
At first when i got the OTA update, my phone started to act sluggish. simple apps like messenger, or google drive that had always worked flawlessly suddenly were taking ages to load. So like any sensible person, i pulled my info to my SD card, took it out, and then did a system recovery to restore factory defaults and start with a fresh OS again, just like when windows starts behaving poorly.
only this did not fix the problem. It persisted with poor performance after the factory data reset and upon my next reboot, my phone just stopped loading when it got to the MI logo on the screen. i literally let the phone sit on this screen overnight thinking just maybe it was being slow to boot after the reset. No luck and in the morning it remained at this screen.
just to make a note:
-phone was purchased off of amazon, i have reached out to the seller(it was a business)
-phone is in CANADA, so there are no service centers
-i CANNOT enter recovery mode(pwr + volup + voldn), it just freezes at the mi screen
-i CAN enter fastboot, but cannot flash room
-bootloader is locked and i have not yet found a method that will successfully unlock it
-the miflash tool does not work(on any version what-so-ever)
-the mi unlock tool gets to 50% and then fails, cannot unlock
-i have installed minimal adb for fastboot, none of the related commands succeed(yes system sees the phone:
c:\adb>fastboot devices
91c0963c0804 fastboot)
-i cannot unlock bootloader here and cannot install twrp or any other recovery image and it will not allow it even temporarily
I've gotten desperate enough to have even gone to the extreme and tried EDL mode by using test point to enter, computer recognizes the device even as the qualcom 9008, still no luck with any of the tools or ROMs provided on Xiaomi's website.
So be real with me here ladies and gents.... should i take this thing on my next trip up a telecomm tower and biff it as hard as i can at the ground(obviously in a snowless area for the most satisfaction) or can you saintly people actually offer me some support on this to turn my brick paperweight back into a phone again?
it is also worth mentioning that this is my first post here because i have never before had a problem with following any of he guides on here to accomplish any task i've ever set out to do with an android device, but this beastly lil mother is seriously making me consider becoming an iphone person(not really but do you get the frustration here?)
I'm writing this at 5:30 in the morning after being up all night working on this task so if my info is missing somewhere along the line just poke me with stick and i will fill in the blanks as needed.
I couldn't be bothered to get and load screenshots tonight but i will get some up tomorrow after sleep, for now i am going to the graveyard to rest.
Thanks for any responses in advance here.

take your sd card off your phone i had similar issues and fixed them that way

it depends on which version of the flash tool is used. the beta version of the flash tool claims that it is successful, but the phone will not load to the Android OS after that is completed and it still will not load into the recovery mode to attempt to factory reset or anything else.
other versions have given errors:
miflash 2017.7.20.0 gives the response after attempting for about 10 seconds of "ACK count don't match!"
miflash 2018.11.15.0 gives the error response of "cannot receive hello packet"
and as stated before the miflash beta goes through the complete flash process with the result stating a "success" response, but the phone will not load to OS, just remains stuck on the MI logo screen when the phone is booting up
i have some screen grabs of all this but i am not yet worthy through XDA to be permitted to share them
thanks for the reply

i dismantled the phone manually bro, when you use EDL mode this way the SIM/SD tray is removed you then remove the entire backplate and then disconnect the battery cable from the circuit board and you use the test point method to short two pins that force the system to start in EDL mode when you connect the usb-C cable, so unfortunately that is not the issue :crying:
it never seems to be the simple solutions
Thanks for the reply!
Still dead in the water on this one.
Going to look into getting a replacement, that is a disappointing end to the Xiaomi experience
Facing similar issue. Am able to flash however still stuck when device is rebooted with this message;
Supported API: 3
E: Failed to clear BCB message: failed to FSync/dev/block/bootdevice/by-name/miscperation not permitted.
Hi All,
I'm new to this as I'm not an Android developer but a good Android user. Requesting moderator to update anything required.
I've Xiaomi mi A1 and it was working for the last 3 years. Last Sunday, it just got hanged while kids were playing with it(maybe multiple apps/videos/some ad clicked) and it got hanged.
I restarted and it stuck on "Android One" screen till now even after multiple attempts.
What I tried:
1. I tried to wipe/factory reset from the Android recovery option(power off + volume up) then it stuck there saying "Formatting data" and I've restarted it to come back to Android One screen after hours.
2. I tried using MiFlash tool and it continues throwing the error "remote device is locked. cannot erase".
Then I got to know bootloader must be unlocked. and for that:
1. I tried fast boot oem unlock but it just says OK and device reboots. When I check status back, it's again locked .
2.I tried to unlock it using MiFlashUnlock tool but it says not able to find account details as I may have logged in once but probably I may not have used Xiaomi as cloud instead I prefer Google cloud.
You can assume I'v already searched possibly all threads on the internet and added here all possible information.
Attached getvar-all.txt output
Is there anyone on the platform who knows on this issue?
Or it's just a platform of Ads?
oooooof, sounds like a harsh brick from some sort of malware downloaded into the device or your kids diddled with some kernel settings somehow
is your device running on qualcomm snapdragon? i have the fix for it in this site
but first try the update option on the recovery, might fix something

found some fix on a russian website, gonna translate it:
im gonna make a warning there off-script of the russian website, this is NOT guaranteed to work. if it doesnt, send it off for repairs.
what do you need to do this:
1 - fully charge the phone
2 - a working usb cable
3 - a computer with wifi on it (i can tell you have it since you likely posted it on the computer)
4 -you should have Mi flash pro
5 - a recovery image on chinese (WARNING: 1.9 GB, BE PATIENT)
6 - actually working braincells and hands ( you guaranteedly have em)
THE STEPS:
1 - Load in mi flash pro and register in it under your name (not always under your name)
2 - press recovery
3 - you should see a lightning bolt icon along with the IMEI of your device
4 - type in the path of the firmware
even if your device shows your system has been destroyed you can still boot into recovery.
5 - in your device boot into recovery
6 - you see connect with mi assistant? choose that option and confirm it
your device should direct you to connect the usb from your computer to your device
7 - After you setup everything you should see your device, if not, press refresh device, then you should see the flash button, press it
8 - and there begins the magic - wait 5-10 mins for the firmware to initialise, DO NOT DISCONNECT THE USB FROM YOUR DEVICE AT THIS POINT, IF YOU DO, YOU WILL SCREW IT UP AND HAVE TO DO IT ALL OVER AGAIN!
if you dont screw up and your device actually boots congratualtions! the power of xi jing ping has restored your phone to normal with a small drawback - its all in chinese
worry not, it doesnt end here:
9 - Unlock the bootloader AKA Unlock OEM (This is important, because otherwise you will brick yourself again and will have to do it all over again)
10 - boot your device into fast boot and flash the global firmware onto your device (the global firmware can be found on the same xiaomiui website you got the chinese firmware from)
i hope this lengthy guide helps

crud, i forgot the critical part:
it doesnt boot you to the average xiaomi screen, its the A1 model
at this point you need to use the ADB to flash the chinese firmware and unlock the bootloader on the chinese firmware, then flash the global one
though you can still use the same method i typed above
How's the progress so far?

Hi i dont have that kind of a problem!
my problem is when i try to do oem unlock it says error 0x1002 and idk what to do (i have same phone btw) i tried anything but nothing works!
Very quick guide for how to return to stock, factory reset, and relock bootloader. This is if you're going to trade in the device or re-sell it.
I am assuming that you're pretty familiar with this process based on the assumption that you unlocked the bootloader in the first place, but it was 2+ years ago so you don't remember the details. This is for you.
If you don't correctly re-install the factory image in step 12, you are at risk of bricking your phone, stop and ask for advice if anything isn't clear or if any step fails.
This will DELETE all your phone's data, proceed with caution.
Tested on Windows 11 PC and Pixel 3a
First make sure you have the Prerequisites here: https://forum.xda-developers.com/t/...ootloader-update-root-pass-safetynet.4443459/
Enable Developer Mode and USB Debugging as described here: https://developer.android.com/studio/debug/dev-options
Remove the sim card from the phone and erase any esim cards, restart the phone and enter your password/passcode, go to the home screen
Download the latest Factory Image (not OTA) for sargo, sargo-sp2a.220505.006-factory-978959e1.zip, to your PC, instructions are in the link in step 1 under Spoiler: Downloads
Unzip the factory image to a known location on your PC
Open a command line tool in the folder extracted above, confirm the flash-all.bat file is in the current directory
Plug the phone into your PC with the appropriate USB cable
Run adb devices on PC, if your device is "unauthorized", then approve the connection on the phone.
Rerun adb devices and confirm your phone is authorized
Run adb reboot bootloader, phone should restart to the bootloader screen
Run fastboot devices and confirm your device is listed
Run .\flash-all.bat, wait until the command says it is done, press any key to go back to command prompt.
Eventually the phone will reboot to Google Setup, may take 10 minutes, don't get worried unless it takes more than an hour or if an error is displayed while restarting
Skip past everything, do not connect to WiFi, do not enter an account, get to home screen
Go to settings and re-enable Developer Mode and USB Debugging
Run adb devices on PC and approve the USB Debugging on the phone
Run adb reboot bootloader
Run fastboot flashing lock
Follow the instructions on your phone to confirm and finally lock the bootloader
Unplug phone and restart it
Confirm Google Setup starts but do not proceed, just power off the phone, it's ready to ship
or just use this official web tool https://flash.android.com/welcome
You still end up needing to have all the USB drivers setup, and will have to run the `adb flashing unlock` using ADB and it is a less reliable process in my experience, particularly if you don't use Chrome.
Does still works if you're coming from an Android 13 ROM or does the "anti rollback" feature not apply to the 3a?
I'm thinking of installing Ubuntu Touch. The requirements is to return to Android 9. Is that still possible? Anyone reverted back to previous Android version?
Haha. Terrible Jan 2023 update. Cellular connection not stable on my P7P while posting this asking for my newly bought Sargon for Ubuntu Touch project
Update: revertable. Even on flash.android.com you can choose previous stable public build including Android 9 ones
