You can install OTA via twrp

First of all you have to unlock bootloader and then type fastboot boot twrp.img

And then open twrp change current slot and then flash this zip file

My phone is bootloader unlocked from September and i got all OTAs

---------- Post added at 02:56 PM ---------- Previous post was at 02:55 PM ----------

Try to flash a fastboot rom via Mi Flash (without wiping data) and see if it fixes your problem

---------- Post added at 03:00 PM ---------- Previous post was at 02:56 PM ----------

You cannot Flash OTA zips directly

All the available flashable ones are modified to work with TWRP

There's a stock recovery but it is meant to flash only test-keys builds, so the official full roms n incremental OTAs (release-keys) will fail to install

[Xiaomi Mi A1 Guides, News, & Discussion] nehalem176:
[MENTION=6345368]Displax[/MENTION] thank you for TWRP image, successfully update without any issue.

Prior flash update, I do have Magisk v16 and Systemless xposed installed.

1. Disable Xposed Framework in Xposed app (don't restart)

2. Turn On Magisk Core Only Mode (don't restart)

3. Disable PIN on Device startup (if any) and change unlock pattern to 'None'

4. Copy tissot-T-OPR1.170623.026.8.3.13.zip into root folder

5. Boot into TWRP by clicking 'TWRP reboot' using Xiaomi Mi A1 Tool by [MENTION=8676627]AridaneAM[/MENTION]

6. Flash "tissot-T-OPR1.170623.026.8.3.13.zip"

7. Reboot then open Magisk then click Install button, it will prompt either 'Download Zip Only' or 'Patch Boot Image File'

8. Just select 'Download Zip Only' then repeat Step 5

9. Flash 'Magisk-v16.0.zip' and restart

10. Open Magisk, disable Magisk Core Only mode, restart, open Xposed then enable Xposed Framework then restart again to take effect (too many restart right? but this certainly no bootloop)

11. Enable Pin/fingerprint/pattern or whatever unlock pattern that you have disable earlier

Because booth won´t work.

Unzipped looks this and i can´t use these =/

first is normal OTA from #1

the 2cend from you

and the third one i thing was G+ a guy and this has many more images in in and was working with twrp.
[Xiaomi Mi A1 Guides, News, & Discussion] Ratha ITC:
Download the correct one!

For TWRP recovery, download the tissot-T-OPR1.*.zip

For fastboot, download the tissot-F-OPR1.*.zip

Use the TWRP method if you're not familiar with the fastboot.
[Xiaomi Mi A1 Guides, News, & Discussion] Maximaro:
Thanks for showing me this...

Sadly i do not get it!

The Toturial from here isnt compatible with the version i already have downloaded =(

see pictures and names of these.
[Xiaomi Mi A1 Guides, News, & Discussion] Ratha ITC:
I've never tried that reversed fastboot ROM. Try at your own risk!

As far as I understand, if you want a clean install by flashing the fastboot ROM, you have to flash the stock fastboot ROM from Xiaomi in fastboot mode, and after that, do not boot your phone (keep it plugged), then flash the latest reversed package "F" by using the "flash_A.bat" (flashing .bat requires fastboot & adb tool sets, so download and copy and paste into the same folder of the flash_A.bat file before flashing).

Edit: Please be noticed that the tissot-F-OPR1.*.zip is for manual flash only. It is not for Xiaomi Flash tool.
[Xiaomi Mi A1 Guides, News, & Discussion] Displax:
So, OK. A few explanations about the installation of this "handmade" ROMs...

https://drive.google.com/drive/folders/1dw87qgRNGxfj7UZduHK91LE6X1Xs7CWL

As I mentioned here:

"F" - for Fastboot.

"T" - for TWRP.

Installation​

TWRP:

1. Temporary boot actual TWRP image or boot up to the already installed TWRP.

2. Download and copy "T" ROM to device.

3. Flash it. It is flashed to both slots (A+B).

Fastboot:

1. Download "F" ROM and unzip it to the any place on PC.

2. Download actual version of Platform Tools utils (adb/fastboot): https://dl.google.com/android/repository/platform-tools-latest-windows.zip

3. Unzip the contents of folder in zip to the ROM folder. Or just this files (full pack):

adb.exe

AdbWinApi.dll

AdbWinUsbApi.dll

fastboot.exe

libwinpthread-1.dll

make_f2fs.exe

mke2fs.conf

mke2fs.exe

4. Run "flash_all.bat" for flash with no wipe or "flash_all_clean.bat" for flash with wipe.

It is flashed to both slots (A+B).

Note:

Ignore error "Invalid sparse file format at header magic". Just wait.

Is the fastboot firmware file available at the first page are full firmware files and can i flash them using mi flash tool?
[Xiaomi Mi A1 Guides, News, & Discussion] marhensa:
thank you for your effort.

but one question,

you do realize there's lot partition besides boot, modem, and system right?

your zip consist only those three.

is it safe?

i mean, real fastboot image normaly have at least 17 img partitions.

when we only flash those three image partition from your zip, the rest partition still have previous release version.
[Xiaomi Mi A1 Guides, News, & Discussion] oreo27:
Edit 3 - As already mentioned by [MENTION=6345368]Displax[/MENTION] and as far as I've tested, we only need the boot, modem and system partitions to be flashed. In addition, before flashing TWRP, Magisk or a custom Kernel, you'll want to boot fully to system to finish the update within Android. Once finished, you can flash all 3 without experiencing any bootloop.

Edit 2 - [MENTION=6345368]Displax[/MENTION] - While I was able to extract the OTA, I'm not sure if this is flashable similar to your ROMS hosted on Google Drive. Upon extraction, I ended up with several files:

aboot.img
boot.img
cmnlib.img
cmnlib64.img
devcfg.img
dsp.img
keymaster.img
lksecapp.img
modem.img
rpm.img
sbl1.img
system.img
tz.img

However, yours has only:

boot.img
modem.img
system.img

Shouldn't we be flashing the other partitions or is there something else to be done after extraction that I missed?

Edit - Nevermind. I got it to work by installing a missing dependency. I've never tried Python before but I've had a lot of experience with NPM so that helped (sort of).

pip install protobuf

Please note that I installed Python and PIP. Both are also added to my PATH. I'm on Windows if anyone wants to do that.

I tried this and I'm getting an error:

C:\Users\User\Desktop\7c05474d9be8a1856d1ca319ddac13eb72839e6f>payload_dumper.py

Full OTA Images installing if yet fully updated

Hi everyone,

so this is my scenario: I am fully updated so far:

Build Number Android 8.0.0 [OPR1.170623.026.V9.5.9.0.ODHMIFA]

Android Security patch level: March 1, 2018

I have a question:

can I install first this OTA

Android 8.0.0 [OPR1.170623.026.8.3.16] via TWRP an then also via TWRP install

Android 8.0.0 [OPR1.170623.026.8.3.22]?

TNX:cool:
[Xiaomi Mi A1 Guides, News, & Discussion] nehalem176:
you can skip OPR1.170623.026.8.3.16 because OPR1.170623.026.V9.5.9.0.ODHMIFA is later version to OPR1.170623.026.8.3.16. Just download link sorting in OP bit confusing to you.

as per my previous post, I do have version OPR1.170623.026.8.3.16 installed but upon checking update, I receive an OTA update notification (around 1GB++) and my version after update is OPR1.170623.026.V9.5.9.0.ODHMIFA
[Xiaomi Mi A1 Guides, News, & Discussion] maxpaguro:
TNX,

so having OPR1.170623.026.V9.5.9.0.ODHMIFA installed if I via TWRP install Android 8.0.0 [OPR1.170623.026.8.3.22] maybe I have April Ota update?:confused:
[Xiaomi Mi A1 Guides, News, & Discussion] nehalem176:
what I've meant is you can skip install OPR1.170623.026.8.3.16. Just straight install OPR1.170623.026.8.3.22.

By the way, OPR1.170623.026.8.3.22 is not April OTA. it's Beta version after OTA update OPR1.170623.026.V9.5.9.0.ODHMIFA

I'm sure this is probably covered somewhere else, and I apologise for the redundancy; but,

Whats the difference between Google's ota image and Xiaomi's?

I was going to ask which to flash, but it seems [MENTION=6345368]Displax[/MENTION] knocked that one out.

I intend to use TWRP, does that change which i use? I got the context that the fastboot img was to be used with the Xiaomi tool.

And lastly, please forgive my ignorance.

I believe the only difference is which server you'll be downloading it from.

If you're going to flash it, you'll want the TWRP flashable version which Displax provides on his Google drive.

The OTA images aren't meant to be flashed using TWRP or Fastboot. If you go that route, you'll need to extract the images from payload.bin using python then create a TWRP flashable zip or flash it using Fastboot. The former method is easier.
