Dear Secondkai,
Greetings !
1st Remember One Thing. Downgrading Is Not A Easy Task. If You Want To Downgrade Your Device From Pie To Oreo, You Need To Unlock The Boot-Loader Then Download Stock Oreo And Flash It With The Help Of IMFlash Tool.
But I Suggest You Double Check And Read Each An Every Steps Two Times Before Downgrade.
Please Refer To Mentioned Below Link...

If you flash Pie modem.img, you'll have video recording issue; if you don't flash it you'll have SIM card slots swapping issue. I just flashed Oreo over Pie (via MiFlash) and it's working good (I don't use 2 SIMs though)

I have the 9.6.11.0 too, latest Oreo. I have 2 bugs so far: SIM cards are swapped (not sure if 2nd SIM works, didn't try) and storage in settings shows I have 30 something GB of apps installed which I don't, but this doesn't affect usage at all.

what is the difference b/w RETASIA, RETIN and RETAIL Firmwares for Moto Z Play India?

Q: what is the difference between RETASIA, RETIN and RETAIL versions of Firmwares for Moto Z Play. Which one is particularly for Indian Moto Z Play?
[Request]: Please somebody upload official stock Nougat 7.0 Firmware of Moto Z Play for Indian version (RETASIA/RETIN)? There is a 7.0 RETAIL firmware version for Moto Z Play https://mirrors.lolinet.com/firmware/moto/addison/official/RETAIL/XT1635-02_ADDISON_7.0_NPNS25.137-24-1-4_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip but I doubt that it is not official for India. So please upload stock Nougat 7.0 for Indian version (RETIN/RETASIA) Moto Z Play.

Baseband is the important part of the Firmware. As you say that they have different basebands. So which baseband version (RETASIA or RETAIL) is for Indian Moto Z Play?
Nobody is telling the exact difference between RETASIA, RETIN and RETAIL versions of Firmwares for Moto Z Play.

But there is no RETIN firmware for Moto Z Play. There are only two types of version for Indian Moto Z Play i.e., RETASIA and RETAIL. As you said you have checked the RETASIA version but what about the RETAIL version firmware for Indian Moto Z Play?
And why are you talking about RETIN? Do you type RETIN mistakenly instead RETAIL? And If not then where you find it? I can not find it anywhere?

Why my Moto Z Play become bit laggy after unlocking my bootloader? I am on stock Indian Nougat 7.0 ROM (latest updated March security patch) and have installed twrp recovery and Magisk Systemless root v12 without messing any system file/partition. Mobile seems little laggy/jerky sometimes in settings and apps. This problem was not before the unlocking bootloader and installing twrp recovery and Magisk systemless Root. I have also factory reset the mobile and also wipe the Dalvik cache, cache and Data through twrp recovery. But I didn't get any improvement then I reflash stock nougat rom. But the problem of laggyness/jerkyness still existed. What should I do? Any fix or any suggestion?
And please also tell me does most of the android phones get laggy after unlocking the bootloader or after installing the Root?

Q1. Yes I have installed the stock Nougat Rom (RETAIL version) with stock recovery but I still get laggy experince some times especially with jerky/laggy status bar and toggles.
Q2. And also please tell me that during installing stock nougat ROM, should I completely install all the files in zip like bootloader and modem files etc or just install system files, recovery,boot.img, without touching any modem files & bootloader?
Q3. Currently I am on stock nougat 7.0 Indian Rom, so please tell me 100% accurate safe method (adb commands) to install RETAIL nougat stock Rom.
(Please read all questions and give all answers step-by-step. And please give complete answers. Please, No short answers. I Will be very thankful to you for your help.)
Hey, Mate, I got lags on stock nougat even without root and twrp.
I really doubt that systemless root is to blame here, and definitely not TWRP, since there is no possible way it can affect system performance.

Which custom GSI ROM works well with the stock Android pie?

I've been using Pixel experience ROM without issues until I upgraded my phone to latest pie and went back to the custom ROM. However, the fingerprint is not working on Pixel Experience again.
Any help on a working GSI ROM will be appreciated. Thanks.
Good question

Hello,
I tried AEX, Arrow, Descendant and Havoc (On android Pie)
The screen border are good only on havoc and the fingerprint work.
Fingerprint doesn't work on AEX sure. I don't remember on Arrow and on Descendant.
Here a list of the GSI Rom:

PS : Doesn't forget to flash GAPPS
I'm here if you have any question !
Sorry for my bad English,

Wich havoc version?
Worth a try? Or better stick with stock?
How is the camera?
Thx

Hello,
27/10/18 update, official download link,
https://sourceforge.net/projects/ha...0181027-GSI-ARM64-AB-Official.img.xz/download
This GSI is beautiful, there is a lot of possibility to customize with full darktheme. If you don't want to use the gapps you can, else you have to flash open gapps. Personally my two favorites gsi are Lineage OS and Havoc OS because Havoc is based on Lineage.
The Camera is the google camera, the same camera of the pixel experience rom.
If you have to install a gsi install havoc.
Pierre
The pixel experience fingerprint bug also happened to me. What i do is repeat the whole flashing by flashing stock 9.6.4.0 in edl and then flashing the gsi. Works well again. Btw im using havoc it has alot of customization and features but not so fluid

Thanks for the response. But have you tried the latest stock pie for mi a2 lite before going back to those custom ROMs. Downgrading from pie screw up the Sim 1slot. I don't know if you've noticed that.

I tried what you said bro. From pie 10.0.2, I downgraded to 9.6.4.0 via edl flashing.
However, the Sim 1 slot does not work. I repeated same procedure flashing 9.6.9, same outcome.
Eventually I had to re-flash 10.0.2 to make the two Sims work.
Problem with flashing GSI ROM on 10.0.2 is that the fingerprint does not work. You cannot even do fingerprint registration.
In the end, I had to install the GSI (pixel experience) not minding a screwed fingerprint.
The ability to copy texts from recent apps is one cool feature of that ROM that I can't meet go
Câmera does have Night mode?

to fix sim cards you need doing some commands from PC when phone in TWRP mode:

exit

SIM Card Swap after downgrade from Pie

Hello
First I'd like to apologize if I made thread at the wrong place
A few days ago I tried some custom ROM base on Pie like RR , Arrow, Liquid Remix, MIUI.eu, etc. (I can't remember exactly all of them.)
And then I went back to Oreo stock ROM. But so weird the SIM card now swap from original. (SIM 1 become SIM 2 & SIM 2 become SIM 1.)
I already tried many ways but still no luck until now. (Flash Pie again & downgrade to oreo.)
This also happened to my Mi A2 Lite before & already solved by replace modem.img file in Oreo with same file from Pie when flashing.
Unfortunatelly the method from Mi A2 Lite can't be applied here cause sakura doesn't have modem.img file.
Would be very appreciate If anyone know how to solve this & willing to share here.
Thanks a lot

You have flashed Pie version eu.
That problem wont happen with AOSP based roms like RR, LOS, Viper etc.
Many people lost their VoLTE also. As of now there is no solution(As far as i know). You have to stick with Pie build itself. If you fixed it, let us know.

Even if I flash back again to Pie (MIUI.eu, RR, LOS, also Mi-globe, etc) the problem still exist.
I have tried with other SIM card as well. But nothing fix.
So I guess must wait for next update to get fix. Thanks for the answer.

I'll still stick with android oreo 8.1 till now. If I flash miui android pie 9.0 (maybe u mean android 9 ? ) , I will activate ARB which I avoid it. So I can keep the getvar anti version null.
I already tried to flash the latest firmware from yshalsager but nothing has change. The problem is still exist.
You can try & let me know the result. Good luck.

No it's a problem, even if you flashed firmware-less most of the functions won't work, at least that's what happened with me, no camera, no earpiece, no vibration and ofc more under the hood.
We're stuck on pie and even the custom ROMs need to be updated to the new vendor because the situation is the same.
Pie is so far so good but I'm surprised that exFAT isn't working!! now my sdcard is useless! i checked and the module is missing which is exfat.ko, don't know if they forgot to add it or what now!! also all the recoveries i tried give a problem with data and encryption so it need to be updated, other than that all is good.
Anyone tried latest xiaomi.eu build 9.3.25?

TBH I didn't try because of the problems I heard people were having. But with the original pie update I had to use orange fox recovery just to get out of encryption it was a mess. I am going to try to flash a pie rom but if you are flashing an Oreo MIUI make sure the firmware folder is not in the zip or you will brick your device.

Agreed. This seems a bit strange for me. Are you sure guys you cant simply go back to Oreo?
As long as anti is fine, it should not be a problem. Maybe there is a new mechanism now which we dont know.

I've Installed China and Global Pie then reflashed 10.2.2 without problems with MiFlash, haven't tried with custom recovery, i think you will not have problems.
Guess I will hold off MIUI Pie until its finalized.

Yes you can do anything if the anti version is same..
But Xiaomi recommends not to downgrade to Oreo after android pie update. (There won't be any problem as long as we use MiFlash tool)
Maybe Xiaomi will introduce new anti version for stable android pie update
Here http://en.miui.com/thread-6004916-1-1.html you can read moderator suggests not to flash Oreo ROM after updating to android pie.
Maybe Xiaomi moderator mentions same thing for our device during public beta release
For those stuck on the new miui pie, a possible solution:

Fake as tits.
I downgraded from 10 to 9 including hopping between some custom ROMs here and there and I'm currently running the latest Android 9 version.
Mi A2/Lite has anti rollback so this holds true, Mi A3 however does not.

Going back and forth between android versions on a device with an unlocked bootloader using a custom recovery, and doing so in a stock device are two pretty different things.

Yeah, I think what Xiaomi meant is that apps may have issues with it, which is to be expected as such
I flashed fastboot rom for android 9.0 pie with no issues after getting Android 10 OTA.
How come there are others who has no problems while others have sensor problems
Downgrade and sensor malfunction
I downgraded android 10 to 9 in MI A3 and the sensors are not working after.
light sensor
proximity sensor
gyroscope
compass
non of the sensors are detected following downgrade
how to fix this? if anyone could downgraded without sensor problem please share how .
thank you.
