Xiaomi Redmi 7A missing instructions for stock upgrade to android 10

[Gredin67]

Trying to flash a Redmi 7A to /e/OS. Last week no TWRP was available (it came out today https://twrp.me/xiaomi/xiaomi-mi439.html), although the device was marked as supported.
Also, no instructions were provided to upgrade the device to Android 10 (MiUI 12/12.5), although it was said to be linked in the instructions. Which is the recommended way ?

I think it would be better to wait for all devices to be tested in real conditions before adding them to the list of supported devices. Otherwise, there is a risk that e.g. no twrp is available (only recoveries from /e/OS or LineageOS).

I think in this PR a batch was added without testing of all devices.

Redmi 7A (pine) is one of the phone I have the most tested... At the beginning, it was even working with OrangeFox, but official TWRP was already released when I push this PR. Don't know why you didn't find it last week. It was tested with official Lineage, among others official & unofficial custom ROM... So, what more do you want I test ?

Also, no instructions were provided to upgrade the device to Android 10 (MiUI 12/12.5)

On which version are you? One way is to use https://xiaomifirmwareupdater.com/miui/pine/, download "fastboot" version (so a .tgz file), then unzip it, they execute flash_all.sh or flash_all.bat depending on your OS.

The #226 was tested. Untested PR are mentioned as untested.

Even unofficial TWRP usually works, so we can support it. If we're waiting for official support of all ROMs and recoveries, our list will not be long...

Why did you put the "bug" label? You don't even seem to have tested it.

I've spent more than 6 hours trying to flash the 7A, first time because I did not find the TWRP. Because it was not listed as 7A, but as SDM439 Devices https://twrp.me/Devices/Xiaomi/ And as it was all fresh, it was not indexed in the search engines.

And second time because I could not manage to get the device upgraded to Stock android >10 (which is marked a a mandatory requirement in both LineageOS and /e/OS doc). No OTA available (because the owner of the device had already unlocked the bootloader I guess), and no way to flash a manually downloaded upgrade..

I'm pretty sure I've read that instructions will be added to explain how to upgrade stock ROM. So I'm just pointing out that those instructions are important for this device.

It is the second device in 2 weeks that I test and is not flashing with OAI (FP3 and 7A). I think it is better to have a shorter list that is working 100% rather than a longer list with frustrating experience, which results in users not advertising the tool anymore.

Nothing new here, Redmi 7A has been unified with others devices for years... By the way when OAI recognize this phone, it says "Mi439", it should put you on the right track (or a quick search for "TheRomYouWant Redmi 7A download"...). Potential mitigation: add TWRP link on the device config. (maybe it's already ok, don't remember)

No OTA available (because the owner of the device had already unlocked the bootloader I guess)

Nothing to do with OAI, that's Xiaomi. I already answered to that, please see previous message.

@tsterbak What do you think about adding some instructions for it? I think using brand metadata is enough... Or just a link to the website?

Sorry about hat issue, I'm not the maintainer of FP3. But that's another issue. By the way, the tool works for Mi439, you don't even tested it.

By the way, the tool works for Mi439, you don't even tested it.

Well then close the issue if you think that... OF COURSE I tested the tool, why would I open this issue otherwise, for fun ?
Maybe the tool is able to flash the mi439, but the aim of the tool is not only to flash, but also to help people in understanding the tedious process of flashing a new phone from a new brand. And for Xiaomi, this includes upgrading Stock ROM to Android >=10, Thus NO the tool did not work for me.

OK, you answered here but did not provide a fix/PR. I would consider this issue solved once instructions are added on how to upgrade those devices from stock Android 9 to Stock Android >=10 in following cases :

• OTA available
• Bootloader unlocked
• Bootloader locked

The web is full of misleading solutions on this, reason why I lost so many hours trying.
