Upgrade Mi8 from Pie to Q

Hello everybody,

I am running /e/OS 0.14-p-2021012798470-dev-dipper on my Mi8 and would like to upgrade to /e/OS Q.

As far as I remember, before installing /e/OS Pie on my phone, I first had to install a developer stock ROM.

As I read in the documentation on upgrading /e/ to Q, to upgrade to /e/ Q the Android firmware should be Android 10.

I am unable to find a stock developer ROM with Android 10 for my device.

The only ROM I could find is the stable ROM, for example this one:

Is this the correct ROM to flash first before flashing /e/OS Q on my device?

Thank you in advance for any helpful answer.

Best regards

Hi @philipp,there are different channels to get Xiaomi Stock Android ROM. I use this source and always flash the Fastboot version.

Our Communication Leader has just checked my link to the source. Since there were no objections to my recommendation, it is to be considered serious, isn’t it…

Thanks for your help.
I had a few issues with the fastboot commands on my linux notebook, but now everything went fine and /e/OS Q is on my Mi 8.

Hi @philipp, can you please post the steps you did for anyone to reproduce. Thank you!

Of course.

  1. I downloaded the last MIUI official Global Android 10 ROM from here:
    Thanks @SuzieQ
  2. I followed the steps as mentioned here:
  3. Then I did the steps mentioned in the upgrade advise from /e/:

The problems I had were caused through outdated platform tools. I could solve this with the steps explained in step 2.

I hope this was helpful.

Best regards

Thank you @philipp !
I under stand part 1 as to download and flash the new firmware for the baseband.
What I don’t get is step 2, what’s flashed there? “Fastboot” isn’t that part of a FW?

Reading through part 3 I sense one will loose all important data, basically doing a full wipe. So far so good, but while I have my personal data saved in my nextcloud instance, is there a way to migrate applications, settings?

Hi @heartshapedbox,

step 1 is to download the ROM.

Step 2 is flashing the ROM.
Fastboot is a tool for flashing ROMs on devices, which are running in fastboot mode.
As I used the flash_all.sh script here, every data was deleted. I wanted to do a clean install, so don’t forget to make a backup first.
It should also be possible to use the other script with keeping your data.

I have no experiences with backup and restore app data, as mentioned above, I did a clean install, including all apps and settings.

Did you use seedvault to migrate your applications and settings?
Is that already possible with release v14 PIE?
