[Solved]MiA1 shutdown after Booting UP

Hello guys,
I am providing Log-cat(Removed) for issue present.
Only thing I am think of is that I have restored EIS,Modem,Android Secure,persist from TWRP recovery than this started
For current situation this is stock Rom flashed with Mi Flash tool.
Also lineage OS 15.1 shutdown before showing Bluetooth stopped.
Any idea how to solve this?
or I have to visit Mi Service store?
In last few line in logcat there is something related to Bluetooth.

It's never a good idea to restore data because the stock rom has encrypted data, so once you restore stock rom with twrp you'll end up in a bootloop (happened to me). All I could think of is for you to reflash with mi flash tool.

I have encountered that same problem last June as i returned to stock in preparation of android 9, this is what i did
1. using MiFlash to flash - tissot_images_V9.5.4.0.ODHMIFA_20180226.0000.00_8.0_5773957dcd.tgz - in fastboot
2. i followed Method 2: (skipping to step 3) as described in this link - https://forum.xda-developers.com/mi-a1/how-to/guide-how-to-restrore-persist-partition-t3765643
3. i used this persist.img instead - https://drive.google.com/open?id=1SyzQsyCv_dfxrOUYetG-dtx3RW_4p9H6
4. reboot - hoping that your device will not restart again
5. flash your desired rom as you wish
Hope this helps - it took me almost 2 weeks to crack this case. This could help you also
After that incident I continued to flash other roms - right now im on liquidremix
Goodluck

4-6 months back there was thread why we should not restore efs of someone & proper tutorial for people who messed up their mac address with some kernel.
Now this tutorial on downgrading pie to oreo. I have no idea. Someone's efs would mess your IMEI, wifi mac, Bluetooth mac, thats what i think. But there are tutorial how to edit imei using some Qualcomm tool.
Ask @CosmicDan. He's the expert.

Just flash Oreo on fastboot, with full wipe. Why doesn't that work?

I was having an issue since using custom rom with december fw btw.
and I was mistaken flashing november fw back to solve some calling issue, so I ended up with no signal which should be came from I didn't restore dev's efs backup.
So I start from flashing full clean stock november and ended with bootloop on it, which is something I still curious what cause it.
At that times, I'm on locked bootloader and can't even enter edl to reflash the rom and can't unlock bootloader since the rom still not booting to enable oem unlocking option.
I don't remember what I have done to it, but at times my phone can boot with no signal, 0 imei on sim1 and null on sim2.
So I start to rewrite the imei then everything is back to normal.

Downgraded using the method of restoring boot and efs... Nothing changed for me, imei is the same as in the box of my mi a1. ? Maybe people did something before doing the downgrade that messed up something.

Well you can try it I guess, just backup the EFS partition and other stuff with my backup tool and you can always go back if worse comes to worst.

Xiaomi put out a message on their forum that after the Pie update, the phone should not be rolled back. Its for all Android one models. When users flash an older roms, bootloops occur.

But what he is saying is that he did downgrade EFS, but IMEI didn't change. This suggests that EFS isn't the original source of IMEI after all. Or maybe the bootloader can re-write IMEI and stuff on boot, who knows... Surely others have actually confirmed that EFS cross-flash = IMEI change, right? Not just assumed?
...point is, you can backup your EFS via EDL mode so there should be no risk. If you made a full EDL backup of your own device when you were still on Oreo then you would be golden, as EDL has full access to all partitions.

IMEI problem on october patch oreo rom (stock moto)

Hey guys, I tried flashing the stock moto oreo rom (october patch) through 1. flashing via fastboot and 2. twrp flashable rom.
Both methods worked but I lost my IMEI, regardless of which method I flashed the rom with.
I had made two EFS & Persist backups (one from resurrection remix rom and one from a twrp nougat june patch rom) and tried to restore them after flashing the moto oreo rom, but no success.
Can anyone help me with this? I really want to use the stock oreo rom!

Please help guys!

Try flashing one of the full flashable zips from that thread, get the last one. But in the installer, do not select firmware.
Hopefully that will get you going again. And no, don't ever install an ota.

Thanks for all your help is there any way to fix OTA updates? like relocking bootloader? or should I just leave that unlocked ?
I just installed \POTTER_NPNS25.137-93-4_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml
and am getting a 3g \ H signal now but its a different sim card and service from original card, seems to be working now
Is it just oreo that screws everything up , I know this is all over but its not very straight forward
im no android expert clearly

Bootloader doesn't matter, can stay unlocked.
And the IMEI/4g problem is Nougat only, never heard of someone who lost something on Oreo or when updating to it.
If you flash latest Oreo firmware for your region (endings with 17-xx are US, 13-xx is for the rest as far as I know) you should be good to go.

Will I loose DRM functionality when the bootloader is unlocked?

Just bought a new Xiaomi mi 6T device. My previous phone was a Sony Xperia m6. To unlock the bootloader and get root access was a bit of a pain on the latter. I remember having to backup a ta-partition to secure my DRM-keys.
Wanting to unlock the bootloader on this device I couldn't find any information about backing up and restoring a certain partition to secure the DRM-keys. What I did find was this post on the mi community forum about how unlocking the bootloader results in the widevine beïng downgraded from L1 to L3 (read the post for further details. The only way to reverse that process is to relock the bootloader again according to the the information I found.
So this is my question: Is there a way to keep the widevine L1 version, with better HDR performances, with an unlocked bootloader by backing up and restoring any data or partition on the phone that is responsible for widevine or other DRM content?

No, you don't loose L1. You don't need to backup anything. You will allways have L1 with the official roms (global/eea) and L3 with all other at the moment including china official, xiaomi.eu and all forks.
e.g:
I have L1 with global rom, unlocked BL and magisk.

I'm unlock and rooted, on L1, but u can't install Netflix from play store, so no full HD

I kinda anticipated that, since when you root your device with magisk, Android prevents you from installing Netflix. Which is no problem in my case, since I only watch Netflix on my television or Pc. You can watch Netflix though on an unlocked device if don't root your devices, isn't it?

I just installed magisk and remains L1. Just that the app doesn't appear on play store. Sideloeaded and got hdr working just fine.

i think only SONY has this problem with drm keys and widevine l1..if you unlock the bootloader of any SONY mobile said goodbye to this keys.And the hdr of the camera i think..

I only recommend that you back up the persist partition with TWRP if you are going to change the ROM on the Mi 9T. Some ROMs try to damage this partition and if it does you will Widevine L1 forever as I lost it

No, but you will lose the safeties that could lead in to a persist partition corrupted.
Backup your persist partition and store this backup OUT of the phone, on a cloud or a PC.

If you will flash ANY different ROM, you NEED to format. since the ROM wont be able to access a encrypted data partition from another ROM/Encryption key.
Also, you can do a forum search for the chinese TWRP, i don't have the link

You could try that but I am not sure if that would restore the wiped DRM keys. In some phones (Moto G5 Plus?), backup of persist from other phones would do no good.
Also you can try flashing stock ROM through AFT and see if it helps you.
An please REMEMBER TO TAKE BACKUP before attempting any of the above methods.

Already tried flashing stock rom via AFT, but Widevine stays at L3. I am not risking to flash persist of other device as it may lead to further issues. Please let me know if there is some more efficient way out of this issue. Thanks.

I heard flashing q firmware permanently causes issues with widevine l1. The only way to bring it back is to restore a previous persist backup or flash a qfil rom (not sure about the latter). If you don't have a backup, too bad chief.

Partially correct. QB1 update caused widevine downgrade to L3 but QB2 restored it to L1. Of course, you have to be bootloader locked all the time. Too many theories going around to restore L1 on UBL but none proven, even persist backup method isn't 100%
