Mi A3 screen won't turn on after finishing a flash process - Xiaomi Mi A3 Questions & Answers

Hello,
I did flash my phone in fastboot mode to the official Android One ROM and after finishing, the screen doesn't turn on.
What can I do?
Thanks

You need to provide more information.
You need to at least state which android version you are flashing and which android version/ROM you are coming from.
To me it sounds like you have flashed android 10 on an android 11 ROM. This results in a hard brick due to anti rollback.
Please state the firmware version you tried to flash, the ROM/firmware you are currently using and the process in which you flashed it.

I was flashing from a custom ROM of MIUI 12 by xiaomi.eu to the lastest available of Android 10 in order to get back to Android One.
Thanks

Did you have Android 11 before installing MIUI (did you do the conversion to cc9e)?

There's your problem. There is anti rollback in this device so essentially you hard bricked it.
You can't go back to android 10 stock at all once android 11 is flashed.
The only way to recover is flash stock ROM through EDL mode which may require a Xiaomi authorised account or bring it to a service centre for repair

Then my phone is done... There is no use trying to fix it.
Thanks anyway!

Hello.
I'm bringing this up again as I have now more free time in Christmas. I've been charging the phone fot a whole day but nothing appears. I don't know if I need to send it to a repair store or something.

Miui Stable vs Developer

Hi guys,sorry for this stupid question but after the xiaomi's news about the bootloader re-lock that causes a brick...i'm not sure of anything...so i'im asking this
I bought a mi8 6/64 global version(bootloader locked) so i think that is coming with the global stable.
So if i want to put the global developer can i just download the package from miui website and then install it from.the system update settings on the smartphone without problems?
Like bricks,errors or something weird? ?
If yes...afyer that,can i come back to the global stable without issues?

Sorry but i can't find the answer to my question.
Ok for unlocked bootloader and china/global.
Ok for anti rollback for android 8/9.
But my question is about a Mi8 with locked bootlader and Global stable and developer

Context:
Over the few months i have seen many Mi 8 owners who tweak their phone end up with a bricked device, of all the cases, a huge majority of them is due to the lack of research and jumping into modifying their phones before fully uinderstanding the situation (I almost made the mistake too, taking for granted that all android phones have minimal restrictions)
There are two things to take note of (especially if you decide to tweak your Mi 8/SE):
1. Xiaomi implemented a policy that prevents relocking of bootloader if you install a Global Rom on a China Variant Mi Phone
What this means: You cannot relock bootloader if your Mi8/SE is a China variant and ou have Global Miui version installed (Developer/Stable)
Common mistake(s):
1. Avoid 'Clean and lock' option when using Mi Flash. Only use 'Clean all' or 'Save user data' option
2. Do not relock your Mi8/SE if you are on Global Beta or Developer or Any MIUI rom that is Global
2. Google implemented a policy that prevents rollback to older Android versions for Android Oreo and above Roms. This is for 'Security' reasons and affects MIUI.
What this means: You cannot rollback to an older Miui version (Below Android 8.0) if you already you are currently on Andorid Oreo (i.e Miui 10) and up.
Common mistake(s):
1. Do not restore an old backup with Miui that has any Android version less than 8.0 from Miui 10 ( Android 8.0)
2. Do not install Miui 9 (Below Android 8.0) after installing Miui 10 (Android 8.0 Above)
*Tip: Ask yourself if the Android version you are about to install is lower than the Android version currently installed, if it is, DO NOT flash it. (Applicable if you are currently on Android 8.0 and up)
Please keep all of this in mind before you start tweaking your phone as you will run the risk of bricking your Mi 8/SE. After which, your Mi 8 becomes a very expensive paperweight. I hope this helps to clear things up for many people! Do know that while I disagree with Xiaomi's new anti-consumer policy, i also feel that it is YOUR responsiblility in your own actions, especially when you decide to modify your device and when you do modify anything (not just phones), there are always risks involved. When in doubt, it does no harm to Google it or just ask around in the forums. Moral of the story: Proceed with caution!
For those already bricked:
1. Contact Xiaomi Customer Service and try obtain edl permission to peform Testpoint fix.
2. Bring your phone to a Mi Store and hope that they can help you with it.
*In the case where my information is wrong, please correct me so that I can update accordingly for the benefit of everyone!
Have a nice day ahead and all the best in your phone tweaking adventures! Hopefully I helped you in clearing things up

I have the bootloader that is locked and i would like to leave it locked.
Then, is it possibile to change rom from GLOBAL STABLE to GLOBAL DEVELOPER without unlocking the bootloader and making other "modding things"?
Then(only if the 2 roms have the same android,so not now) can i switch back from DEVELOPER to STABLE (with locked bootloader and only if they have the same android version)?

I see what you mean, so yours is the global version and you want to flash without unlocking, http://en.miui.com/thread-720781-1-1.html (google search). Yes u can, from my personal experience, upgrading shouldn't require data wipe, but if you downgrade be prepared to wipe data, thats the only drawback, but you can definitely do it without a bootloader unlock using XiaomiTool or Miflash as well. For upgrading to developer just use updater app and select package, if not possible then miflash. Be careful flashing, you shouldnt have any problems as of now as long as you stay away from China rom. Miui roms are all ARB:1 which means ARB not yet activated, so downgrade possible. Have a good day ahead and have fun with your new Mi 8, it is a great phone (apart from the EDL lock **** Xiaomi pulled)

you can switch from global to dev with locked bootloader. Just download the dev of Android 8.1 and install it via settings - choose package, this will format the phone. Then you will get the Android 9 8.11.8 update
Thank you guys!
Perfect!

Yes,please add it.
Maybe for the "normal" XDA users it's too easy and obvious...but not for me xD
Sorry guys if i bother you again.
But someone just told me that, yes it's possible to change from global stable to global developer but that i should have the same Android version (in this case right now stable is 8 and developer 9).
Otherwise i should unlock the bootloader and then i can switch...
What do you think?
Download http://bigota.d.miui.com/8.9.7/miui_MI8Global_8.9.7_fb7963a71d_8.1.zip and install it via phone updater.
That ROM was the last beta Android Oreo published.
After installing it, you'll receive an OTA update of the current beta ROM 8.11.8 Android Pie.
Done.
Hi xandreasx,
did you do it? Did it work? I tried and it did not work. If it worked could you send me the link where you downloaded it?

You can keep your data only if you do a backup before switching to beta
I have global stable 10.0.3.0 on global mi 8, locked bootloader. I downloaded 8.9.7 Global dev but the updater app says that it's not allowed to update to an unofficial rom. What version of oreo global dev do I have to flash?

Hello everyone one. Somebody Help me pls
2 days ago I updated my honor 8x(jsn-l22) to android 9 and it was awful. I didn't like so I decided to downgrade to 8.1. I used hisuite to downgrade but the speed of downloading was really bad so I couldn't do it. So I gave it to someone to do it. He flashed the official (8.1.0 oreo) with some tool and when the flashing operation was in 99% it faced with an error user data part. And now my phone is running Android 8.1 but not correctly. The build number is changed to this
(chipset-miamic20 8.2.0.001(00X4)) and system UI is totally different and I don't know what to do now.
We tried to flash other versions but actually nothing is able to be flashed. It comes with error even at the first step of flashing. Every ROM we tried flashing all were unsuccessful and came with error.
Please if there is any way to fix this problem, let me know
The phone is stocked in this ROM.
Here is a screen shot of about device. I'm really disappointed HELP PLEASE.

Unfortunately Iran. I haven't find anything
I read a post about Hisuite in a Facebook group and successfully downgraded to Oreo. PIE was slow glitchy and battery was bad on it. Although i liked the look of it a lot. Specifically in some apps and the usual app switch transitions.
Re
Can you give us a link or maybe copy and paste the instructions here, for those of us not using facebook, please? Thank You
I don't have the screenshot of that post anymore i remember the steps.
You connect ur fone to laptop and connect hisuite. Backup ur fone via hisuite. Go to updates and click install older versions. There u ll find oreo update. Install that update. Do not disconnect ur fone in the process. And also, remove any lock passcode etc. After installation fone ll restart a couple of times ans voila. U r in heaven again ???

I did a full downgrade this more to oreo using hisute after the successful downgrade I then proceeded to use the tools to install Google play and services on the device after installation was complete I rebooted the device once it started back up I tried to laignch the play store which refused to proceed from the sign in screen.
Tried that and still having issues not really sure what would be the next step to get the service to work.

Update I was successful in getting it to work after the downgrade I used the GMSanzhuangqi.apk. Prior to me starting the process of trying to get the google apps to work I initially installed the GMSanzhuangqi.apk and didn't run it per instructions. I installed the Google installer v2 and let it do its thing once that was done I rebooted and it didn't work play store or Google services didn't work either I was getting a blank white screen opened it and installed it. it will manually remove the google apps you may have manually installed before once that done the phone will automatically reboot once I has been rebooted use the Appgalery select China region from the setting and search for Google play store and install it. That's it hope this helps some one else. :good:

They suggest me to install NV - but I don't know what it is. I have no original backup. If it stays that way - do google play, services, gmail work? thanks for any advice.

Check fail (bootloader) Device 7 Binary 6

I'm using the SM-A505FN version but yesterday in sammobile firmware list, I saw that on SM-A505F One UI 3.0 already available so that I try to install the version but I didn't know that it will give me huge trouble. While installing in Odin stuck for 1 hour. Then I realize maybe it's a version difference. So reboot the device and then I saw this error.
I saw a few forum posts that if I flash again with Odin it will be solved but it won't. Because those ( SM-A505F ) versions changed my kernel from 6 to 7, Now I can't install any downgrade firmware and my phone stuck at this error. When I try to install the regular firmware it's giving me another error which is " Check fail (bootloader) Device 7 Binary 6 " Now I can't install anything. Is there any way to solve this problem until One UI 3.0 hasn't released for my model? Like using TWRP or any custom recovery?
Hi, ma friend!
Try to flash the latest firmware for your device model and region, but load only AP, CP and CSC files by skipping the BL (bootloader - leave it blank).
Device 7 binary 6. Means no, your device bootloader is newer than your package/binary your attempting to install. I don't know how to fix that. I've heard of cracked versions of Odin that won't do version checking for some devices but I never got one to work because the phone rejects it, not Odin. Maybe if you had a backup of the entire phone you could dd the entire nand. I think your best bet is trying different roms with One UI 3.1. Good luck.
There is Android 11 with One UI 3.1 update for FN models in Poland (XEO). You can download it and flash it. I've already done it.
Idem lo stesso problema, non fa tornare indietro

What are you going to do? If you are about to use Odin flash tool, the only thing is needed is entering download mode of your Samsung device.

I want to go back to Android 9, currently my A50 is using Android 11, which is binary 7 and Android 9 is binary 5.
I want to use Odin. You said to just deselect the bootloader installation, so I don't need to activate either USB debugging or OEM unlocking?

I don't think it is possible for now. After updating to Android 11, the bootloader won't let you install any ROM below Android 11. You can downgrade by installing a custom rom using custom recovery like TWRP.

I'm not sure if this will downgrade your device. There is a chance your device not to boot up after installing custom ROM with lower Android version. Give it a try and write us back.

My phone model is SM-A505GT, it looks like this ROM was not made for this model.
I'm going to search ROMs for my phone model. Thanks for the suggestion anyway.

General I found OFP firmware for Realme GT CN version :)

To fix my Realme GT, I paid a whopping $25 for a 9008 fix, and the guy who flashed it left the OFP firmware, if you're interested, look into it.
Note: You still need an authorized MSMTool account to flash directly.

Some games offer lower FPS in Android 12, and Android 12 cannot install Deep Testing

The CN version of the firmware is a total disaster, it is pre-installed with up to 20+ useless software
what did you do to turn your cell phone into a brick? I'm on ROM CN with locked bootloader, I'm thinking about installing ROM IN.
