[Xiaomi Mi A2 Lite ROMs, Kernels, Recoveries, & Oth] alopez_666:
Yesterday I installed SUPERIOR OS with bluetooth improvement (SBC Codec I think), maybe it is the same bt improvement than your rom and it does not work for me: no ringing sound when in call and no audio sound playing music, so the point is: the more bluetooth improvements, the less bluetooth works.

All of this what I'm telling is just my experience, and now the question: is there any way to rollback bluetooth with improvements to the first one with no improvements at all??????? I mean: I do not want you to do it, I want just to know if I can do it somehow.

Sorry if I am the only one complaining about this but I am facing this issue with all roms. Thanks in advance.

I installed AEX GSI and bluetooth works 100% but rom seems unstable for me (apps won't start unless you reboot phone 3 or 4 times) so I uninstalled it. Another question: is there a way to port bluetooth from this rom to another one????

Thanks in advance.

Did u have installed magisk 19.3? Maybe is the reason for the open delay, work without problem with 18.1
[Xiaomi Mi A2 Lite ROMs, Kernels, Recoveries, & Oth] alopez_666:
Yes, I'm using magisk 19.3, I'll give a try with 18.1

[Xiaomi Mi A2 Lite ROMs, Kernels, Recoveries, & Oth] alopez_666:
I installed the rom without magisk and bluetooth did not work as it should, afterwards I tried installing Kernel, nothing happened, so I do not know where is the problem.
[Xiaomi Mi A2 Lite ROMs, Kernels, Recoveries, & Oth] solved:
try a clean installation, stock firmware first 10.0.9.0 , then reflash the rom , with DragonHeart Kernel
[Xiaomi Mi A2 Lite ROMs, Kernels, Recoveries, & Oth] alopez_666:
Not all gcam apps work, the one I use (and it works) is 5.1.018.177470874. I do not remember where I downloaded from, sorry.

I doubt the 10.0.9 is the problem here. I use the 10.0.10 and flashed it without any issue.

You might want to skip gapps first: so wipe Data, ( I also wipe system, internal too), flach AEX, TWPR 3.3.1 offfain and Force Encryption Enabler. Change Slot, reboot to recovery. flash kernel (optional) and magisk 18.1 (optional). Reboot. Set up devices/AEX. Reboot to recovery and flash gapps.

Hello

Hi there, i tested many custom roms (AEX Rom, Superior OS, EvolutionX 2.0, AOSIP Rom, Havoc Rom, Others...), and i could find a great trouble (for me), when I use my FM RADIO then my sensor proximity call is not turning of, I am sure that the problem is the FM RADIO...so maybe it is not compatible...I was thinking in a solution...it could be to put another APK FM RADIO (maybe from marshmallow or nougat - great apk). Thanks a lot for your awesome.

[Xiaomi Mi A2 Lite ROMs, Kernels, Recoveries, & Oth] celrau:
This is the second rom I see with custom vendor and I need a few clarifications. Would this custom vendor be universal or each rom with its own, will it be the new standard? I can see the benefits of not relying on stock vendor but if say, I want to try out AEX with custom vendor will I be able to go back to my current rom which uses stock (just flash vendor.img)? I'm just trying to avoid spending hours figuring this out on my own...

Thanks.
[Xiaomi Mi A2 Lite ROMs, Kernels, Recoveries, & Oth] acras1:
This vendor will be quite common. And yes, if rom was not built with new trees but with offain's one, you should flash stock vendor.

Honestly, I haven't tried to use previous build with custom vendor

Hello..

Tried both vanilla and gapps ROMS (not today's builds, previous ones of 3/10)...

Followed instructions (https://github.com/tkchn/daisyinstall/blob/master/README.md) to the letter...

After final reboot in both cases ROM was staying in green circle without booting to ROM... Was waiting for over an hour in both cases, though nothing happened...

Before starting installation I flashed stock 10.0.13.00 through MiFlash...

Any clue, how to try it again?

TIA

[Xiaomi Mi A2 Lite ROMs, Kernels, Recoveries, & Oth] celrau:
I know, I had a hard time flashing this myself. Everything became a lot more unpredictable and difficult since this stupid a/b partition scheme. My base is 10.0.9.0 and it took me like 3 tries (stock+AEX) to get it to work. I didn't use miFlash but fastboot flash_all.sh (or .bat if on Windows) and TWRP 3.3.1. So keep trying following the mentioned instructions.

Hello...

Thank's for answering...

MiFlash uses the appropriate .bat file (cause it's windows only)...

So in my case, it used flash_all_lock.bat to also lock back the bootloader...

I think it's right... But I'll try your suggestion, too...

I also use TWRP 3.3.1 from Offain... If that matters...

Theodore

P.S Maintainer might have a clue as of what causes this? Any other suggestion?
[Xiaomi Mi A2 Lite ROMs, Kernels, Recoveries, & Oth] celrau:
So how do you flash/boot TWRP if you lock the bootloader? If you can unlock again it try following the instructions ad litteram. Unless I'm missing something..

Update May 23 2019

Now with new Twrp wzsx150 u dont need to follow this Tutorial to get full Backup to work because twrp can Auto decrypt your files

For all Who followed the guide already and want a encrypted device. Do a Format and dont use remove forceencrypt.

New twrp

https://mega.nz/#!TG4RwCrJ!9E0gOOoDaWjtSIS9GoB0pGvCc2BhRU7rSTNNJbAeUxc

---------------------------

Hello

Many people ask me to make a Tutorial HowTo have a full decrypt phone with full backup working.

Before we start u need to flash the newest Recovery from wzs150 Team https://mega.nz/#!WOZEBCpD!UlyCdDaP-UxuwvzLzDE4yzaqi5qMz-I8iOkseQ5gmP0

Steps to flash recovery should be already known or are available in other Threads on xda

So Now lets begin.

First of all you need to know you need to do format Data through the following process. So Backup your Data on your PC, TWRP NOT working

Lets Start.

1. Boot into TWRP

2. Format Data in Wipe Section (The one you need to type yes) i dont reboot TWRP after that

3. Flash the Rom u want

4. Go Back to the Start Screen of TWRP and Click "Advanced" and "RM Forceencrypt"

5. Uncheck "Remove DM Verity" and check "Remove Forceencrypt"

6. Now youre phone is full decrypted and Backup of all partitions are working

7. If u want Magisk flash it now

Notes:

Dont boot your phone before you did the "RM Forceencrypt" step or your decryption gets lost

If u update ur Rom you ALWAYS need to do Step 4 and 5

If u coming from another Rom and want to restore the Rom u need also to restore "Boot"

If u flashing now another Rom you dont need to do format data,wipe data is enough, but always RM Forceencrypt after Rom Flash

Have a nice day

Greetings from Germany

[Xiaomi Mi 9 Guides, News, & Discussion] baszu:
Thanks for the step. I can backup now.

But the next time I update, always need to repeat "Remove Forceencrypt"; otherwise, phone cannot boot.

Assume this is needed until future update twrp version. a bit inconvenient, but ok.
[Xiaomi Mi 9 Guides, News, & Discussion] simcold:
Hello. I now use xiaomi.eu I don't want to format data.

I do a step 4 and 5 and can't backup. When I want to boot system nothing.....

I back to Twrp and make reverse step 5 and flash the same rom I have and system working fine. How to make backup without format data?

[Xiaomi Mi 9 Guides, News, & Discussion] MangoMC:
Not possible. Maybe only wipe of data works but i didnt tested it. Twrp cant decrypt the data on your Phone it can only prevent the Phone to encrypt it
[Xiaomi Mi 9 Guides, News, & Discussion] doggydog2:
still no encryption support with twrp beta 10:( people call formatting data "decrypt" or "unencrypt" all across board, so it adds to false expectations. would never turn off encryption to get, like, backup?
[Xiaomi Mi 9 Guides, News, & Discussion] vtec303:
Is the b17 still good if I want to decrypt ? b17 and follow the rest of the decryption steps you have mentioned ?, or shall I flash b10 if I want decryption ? cheers.
[Xiaomi Mi 9 Guides, News, & Discussion] MangoMC:
U can use both to decrypt with my tutorial. B17 only can decrypt the Data Partition while its encrypted. So u can Backup All data with b17 without the need of remove forceencrypt

OK cool, I get it, thanks for the quick reply, cheers
[Xiaomi Mi 9 Guides, News, & Discussion] reg66:
I've not ried it yet as I don't have the phone yet, but apparently this twrp (mi9-3.3.0-9.0-b17) supports encryption, you can use it to backup your encrypted data partition. Though, I'm probably too late and you've wiped already...

EDIT, just read the rest of the thread, seems I'm a bit late to the party! That twrp is already mentioned!!
[Xiaomi Mi 9 Guides, News, & Discussion] picitup:
I just installed B17 and backed up to SD. Seemed to work fine :)
[Xiaomi Mi 9 Guides, News, & Discussion] vtec303:
Is that the twrp full rom backup you are talking about ?, backup has always worked for me its the restore which does't works and always ends up with an error, cheers
[Xiaomi Mi 9 Guides, News, & Discussion] picitup:
Ahhh no. I tried to backup with earlier versions of TWRP and they failed with an error message. This version seemed to backup OK, but I've not tried a restore yet.

I'm just playing with Titanium backup so once I've got a good backup with that, I'll try TWRP B17 and report back.

[MENTION=614135]vtec303[/MENTION] I just had a play and restore seems to work fine. My TWRP is:

recovery-mi9-3.3.0-9.0-b17.img by wzsx150.

Here's what I did:

Booted into TWRP and backed up Data, System and Boot to an OTG SD card

In TWRP performed a factory reset.

Booted into System, went through the Android setup (not wifi) and checked that all my 3rd party apps had disappeared, I had no SMS or calendar events.

Booted into TWRP and did a restore of all 3 partitions from the previous backup.

Booted into System and found all my 3rd party apps, SMS, Calendar and could browse the web so wifi was configured.

Hope this helps

Cheers
[Xiaomi Mi 9 Guides, News, & Discussion] picitup:
Just a bit extra....

As we know, TWRP doen't back up media data (photos music etc) but I was interested to spot that a factory reset using TWRP doesn't delete all that data either. Pretty handy for me as I'm testing out some backup packages and I don't have to restore all my media files lol.

Cheers
[Xiaomi Mi 9 Guides, News, & Discussion] vtec303:
ok sounds good, I am gonna try that with that b17 twrp, previously I backed up rhe full ROS rom (boot, system and data} on the internal storage using b17, then I wiped system, data and cashes and tried restore but it was a no go for me, may be cos I backed up on the internal storage? but can I ask why did you backed up on a OTG and why not on the internal storage? cheers buddy.
