Question How do I install ArrowOS 13.1 - Xiaomi Mi Pad 5 Pro

Hi All,
I'm trying to install ArrowOS13.1 on my Mipad 5 Pro without sucess and wondered if anyone had been sucessful?
I tried some stesp I found here https://forum.xda-developers.com/t/arrowos-v13-1-mi-pad-5-pro-12-4-dagu-step-to-install.4579335/ but just up to the flashing the payload file as I don't think the vendor boot etc are required since I think those steps were to get the elish rom working on a dagu device.
From the start it didn't go well. I had the Lynnrin rom on originally. When I went to flash 13.1 it worked, but although I had the vanlla version the tablet had gapps on it, Doh, I need to wipe the data partition. So I did that with XiaomiToolv2 (i think it was a few days ago), but after that no booting at all. Damn, ok lets recover with XiaominToolv2, i've done that before sucessfully. That failed becuase because no matter what I could not get into fastbootd mode. But i eventually got the machine flashed by using the flash_all.bat file in the stock rom from XiaomiToolv2 by using an updated fastboot and shortening the file path to the rom. What I didn't realise at the time was thatit was now a different version of the rom (MIUI 14 now)
So great I've got stock back. Now I try to flash the payload filefor 13.1 which flashes, but won't boot. I tried swapping slots for booting but that didn't help.
Has getting it on MIUI 14 locked me out?
I don't want to flash back to MIUI 13 stock as I've heard XIAOMI has an anti rollback thing in place that bricks devices (but I think but not willing to bet, that this doesn't have anti rollback)
Thanks

Hey crass00,
If you're still wondering on how to install Arrow 13.1 on elish, I think you can just follow Lynnrin's past instructions on installing Arrow 12. Copy-pasted below (credit to Lynnrin, modified for clarity, link replaced with the new one you posted in another thread):
Spoiler: Install Custom ROM on Mi Pad 5 Pro (elish)
1. Unlock bootloader
2. Reboot to fastboot
3. Flash MIUI Recovery by this command fastboot flash boot miui_recovery.img
4. Reboot to recovery by this command fastboot reboot recovery, and format data on MIUI Recovery
5. Hold power button + volume down, when screen off, release power button, release all button when it get in bootloader.
6. Flash AOSP recovery by this command fastboot flash boot aosp_recovery.img
7. Reboot to recovery by this command fastboot reboot recovery
8. Enter to sideload mode by this command adb reboot sideload-auto-reboot
9. Sideload zip by this command adb sideload ***.zip (change ***.zip to the Arrow13.1 ROM zip file, in my case I used Arrow-v13.1-elish-OFFICIAL-20230426-GAPPS.zip)
10. Once that custom ROM installed on your Pad.
p.s. on number 9, when sideloading the ROM, the percentage progress seems to be stuck at 47% for a long time for me, don't panic and just leave it for a few minutes, it will magically finish the process and reboot the tab automatically.
I don't think there's any need to flash back to MIUI 13 as I've also made the mistake of flashing it to MIUI 14 first, and there doesn't seem to be any problems so far.

Super that worked. Many thanks.
I actually tried this way last night but failed at the step to delete data. I don't read chinese so couldn't delete data, figured I'd just wiped the device fully with a MIUI restore anyway so whats the need and moved on. That was a mistake With the confirmation it works i installed google translate on my phone to find my way though the menu.
I hope now once an update comes out the data delete step isn't required. That could get annoying if it is

Yeah, I'm wondering about that too actually.
My assumption is that the aosp_recovery.img is already installed as the recovery, so maybe we could just start from step 7?
I'm completely unsure though.
For other devices that I used usually there's a working TWRP recovery and I could just do flashing/updating through TWRP.
At least there doesn't seem to be any major bugs for this Arrow 13.1 build for elish (dagu in the other thread has camera problem).

What's wrong with the official instructions from the maintainer?

Didn't notice it

i can verify this device does not have anti-rollback
I once went from android 12 to android 11
and from android 13 to android 12
so it should be just fine
it's just that sometimes miflash showed an error after flashing

I succesfully flashed this on enuma after 2 attempts using Lynnrin's past instructions but with the newer build
first attempt was with miui 13 (Android 12) but it automatically stopped at 47% and rebooted so it didn't fully flash arrow
for my second attempt I first flashed miui 14 (android 13) and then did the same process again but this time it worked just fine
I guess the logic is that you have to be on the android version you want to flash
camera works (on dagu it doesn't for some reason)
and the xiaomi smart pen also works
edit: is it just me or does the wifi feel slower?

Click to expand...
Click to collapse
All process being run by AOSP recovery will stop at 47%. But you will be noticed by a line of message saying successfully or not.
In my case, I flashed MIUI Android 12 and using A13 GSI ROM. Everything works fine except the GSI ROMs do not support Xiaomi peripherals.
