How to unlock bootloader without wiping data? - Xiaomi Mi A3 Questions & Answers

I've read a guide for mi a2 that after unlocking the bl , holding volume down helps reboot to fastboot mode instead of wipe data menu . Does this work on mi a3 too , as I have data I can't afford to lose

It was a bug on A1/2 and it's been fixed already as far as I know. It's a serious security flaw, so hopefully A3 got it right. Backup your data before BL unlock.

Ok thanks. How do I backup app data?

Some apps backup data on Google drive, others allow manual backup and for the rest you're out of luck without root.

Without root it seems that you'll have to backup your data on external sd card and reset the phone

SMS failure after root with Magisk

Hello,
maybe someone would be able to help or explain. Running on 9.1.0.215 (but tried with 9.1.0.210 as well), after I try to root with Magisk (=flash patched recovery_ramdisk), my SMS stop working. I've tried more applications (default 'Messaging', Google 'Messages', also Facebook 'Messenger') but no chance, phone is not able to receive or create any SMS messages. However, everything else is working fine.
I'm pretty sure that it's caused by this activity, because when I flash back original RECOVERY_RAMDIS.img, SMS are back again.
Any ideas what could be wrong? I really like to use Magisk, but unfortunately, it's no go without SMS.
Thanks!
1. Flash stock recovery_ramdisk. (If you already flash magisk patched ramdisk). Stock recovery is needed to factory reset.
2. back up your data.
3. reboot to recovery. Perform factory reset
4. Power off device. Hold volume down, plug usb to boot to bootloader.
5. flash magisk patched recovery ramdisk
6. Reboot by holding power + volume up button.
7. Done

Thanks for hint!
Doing factory reset isn't exactly one's wish, but if there is no other choice I will definitely give it a try. Speaking of backup/restore of apps - can you please give me a hint, what could be the most comfortable way of doing that? I do not care about data - that is easy to backup/restore - but is there any simple way how to avoid manual re-installation of all apps after restore?
Thanks again!

Hi, just to confirm that I had exactly the same problem. To solve it, I had to reinstall the original recovery ramdisk.

When you go through the setup it should suggest it if you've backed up to drive. Otherwise use titanium backup. It saves the apks and works with root

But reinstall original recovery ramdisk means no root, right?
Did you succeed with rooting afterwards, e. g. with factory reset like suggested above?

I ran into this problem on my honor 9 and in addition to a not working sms-app,the dialer app was broken aswell.
I did find this thread https://forum.xda-developers.com/mate-10/how-to/fix-messages-dialer-9-1-root-required-t3955964 and this fixed both issues.
adb shell
su
rm /data/user/0/com.android.providers.telephony/databases/*
rm /data/user/0/com.android.providers.contacts/databases/*
Go back to phone and wipe data of Phone and Messages
Go back to command prompt and:
reboot recovery​

Glad I could help I tried a factory reset and rooted afterwards, but as soon as magisk was flashed, sms stopped working and tons of "access denied" or so errors started to show up in the log.

I unlocked my bootloader last year, when you could get the unlock code from their website. Unlocking your bootloader on Pie with one of those codes should still work.
I don't know, if other unlocking method like dc-unlocker or funkyhuawei will work. Sry

Thank youuuuuu this worked perfectly for me. I had to change the directory name from user to user_de, but once I did that, it was perfect And I didn't even lose my text messages
Oh no This solution worked, but after doing it, I no longer have access to 4G/LTE on my phone. Did this happen to anyone else? Is there a fix for this?

How do I enable encryption?

Hello there,
I had rooted my phone before the official TWRP came for POCO with the support to decrypt encryption. I used to flash DFE then which disabled the encryption on my phone. I use the Official TWRP now which support decrypting the phone. I want to enable encryption again for my POCO F1 to make the files inaccessible in case my phone is lost/stolen. How do I enable encryption on my phone without formatting the data?
Edit: I just ran getprop ro.crypto.state in shell and it says encrypted. I am confused. If my device is encrypted then why does not TWRP ask me for a password to decrypt my phone when I boot into recovery? Please help.
It is encrypted with the default android key right now, thats why you got that message.
To encrypt with your private key, go to Developer options and Encrypt device using lockscreen password(at the bottom). This is in MIUI 11

Got it. Thanks! Will there be any issue if I enable it now? I am on stock miui 11.0.8.0 with bootloader unlocked and rooted with Magisk. I just don't want to lose any data.

Sorry can't help you there. I'm running locked bootloader with 11.0.8.0. It worked perfectly here without losing data but I have no idea about unlocked bootloader.
I guess you can just make a full backup and give it a try. Best of luck, let me know how it goes!
REFLASH the desigred vendor image and reboot you will be encrypted on your next boot
usually data will not be deleted but its always best to take backup

There is an option to enable encryption in the settings as mentioned by Nik2424 "To encrypt with your private key, go to Developer options and Encrypt device using lockscreen password(at the bottom). This is in MIUI 11"
I am attaching the screenshot of the same with this post for your reference. Can I enable this setting without losing data and root?

Xiaomi Mi A3 "Can't load Android system" error

Hey guys, I would like to ask for advice.
My phone suddenly stuck at this screen:
Android Recovery
Xiaomi/laurel_sprout_eea/laurel_sprout
10/QKQ1.190910.002/V11.0.2.0.QFQEUXM
user/release-keys
Use volume up/down and power.
Can't load Android system. Your data may be corrupt. If you continue to get this message, you may need to perform a factory data reset and erase all user data store on this device.
- Try again
- Factory data reset
Its very similar to an issue already discussed on this site: https://forum.xda-developers.com/mi-a2/help/xiao-mi-a2-load-android-t3993067?nocache=1
However, in my case, i'm unable to access the Recovery menu. It results in Error screen: https://imgur.com/a/2rPDGQa
I would really appreciate some help as i have data inside my phone which i need. So if possible i would like to retain the data.
Thanks for your help!
If you have already unlocked bootloader, flash TWRP, make backup of all partitions and copy it to the PC. If you're still with locked bootloader, then I'm afraid you're out of luck. There is probably no way how to restore user data.
Also happened to me not long ago, interesting, did you do some system changes before that?

No, I don't think so. Although there might had been some kind of a system update few hours before.

Hi @_mysiak_ I'm in a similar situation (Mi A3 too) but instead of eMkoC4, I can access to Recovery menu. Is there anything I can do to recover some data?
Thanks in advance, Simone

I would try pulling the data via ADB (if you have it enabled) in stock recovery. I am not sure how it will behave with encryption, but it's worth a try. Boot into recovery on the phone, connect it to the PC and use this command on the PC:
"adb pull /storage/emulated/0"

In such case I'm afraid that you're out of luck as well (it probably wouldn't work anyway due to encryption).

But i am thinking how any locked bootloader device can go into boot loop, without doing any wrong to it

I did made a mistake by flashing the stock firm in EDL ( therefore, the unlocked bootloader will be replaced by the original one, locked ). But lucky me, it was an OnePlus 9 Global

The exact same thing happened to my factory Mi10. It went into boot loop for no apparent reason and now I have a locked bootloader and am desperate to save my data, which has the only video of a deceased relative. So far nothing has worked and I need some help

Mi flash tool with "authorized account" (required for latest snapdragon devices) to flash in edl mode with option "lock" will relock the bootloader
Otherwise all other options available to flash in edl mode will not relock bootloader, as i know
