Detailed Guide for Installing PostMarket OS on Xiaomi Mi A2 Lite (xiaomi-daisy)

Written with 💖 by DiabloSat

Prerequisites

• The device bootloader must be unlocked.
• platform-tools installed on your PC.

Preperation

It is recommended to flash the latest stock firmware before installing PostMarket OS

1. Select your desktop environment and download the prebuilt images (example 24.06/sxmo-de-sway/20241127-1248): Xiaomi-daisy 24.06 prebuild images link

2. Extract all archives, rename files, and move them to a separate directory for convenience

3. Download the updated, modified lk2nd.img for your touchscreen and rename it to lk2nd-updated.img"

   You can download either of the two images, and if your touchscreen doesn't work, you can reflash the other image

Flashing

1. Enter fastboot mode and connect the device to your PC (POWER + VOLUME DOWN).

2. Load the lk2nd.img loader into RAM

[!] If you skip this step and directly flash the updated loader lk2nd-updated.img, you won't be able to flash the boot.img!

3. Flash boot.img to the boot partition

4. Flash the updated loader with modifications for your touchscreen (lk2nd-update.img) to the lk2nd partition and reboot into it

5. Flash the system image (userdata.img) to the userdata partition and reboot

Fixing "mdtp image is corrupted" Error and Fastboot Bootloop

After step "Flashing (Step 5)", there is a high chance you'll encounter a fastboot bootloop and see the error "mdtp image is corrupted" when trying to load the lk2nd loader into RAM.

What's the Problem?

When you flash the updated loader lk2nd-update.img, your active slot changes to Slot B (and Slot B has no valid data)

Simply switch the active slot back to Slot A in fastboot mode and reboot

Подробный гайд по установке PostMarket OS на Xiaomi Mi A2 Lite (xiaomi-daisy)

Написано с 💖 от DiabloSat

Предварительные требования

• Разблокирован загрузчик устройства
• Установлен platform-tools

Подготовка

Рекомендуется установить последнюю стоковую прошику перед установкой PostMarket OS

1. Выберите окружение рабочего стола и скачайте уже предварительно собранные образы (например 24.06/sxmo-de-sway/20241127-1248): Xiaomi-daisy 24.06 prebuild images link

2. Разархивируем все архивы, переименовываем и перемещаем в отдельную директорию для удобства

3. Скачиваем обновленный, модифцированный образ lk2nd.img под ваш сенсор и перименовываем в "lk2nd-updated.img"

   Можно скачать любой из двух образов и если у вас не будет работать сенсор, то просто нужно будет повторно прошить другой образ

Прошивка

1. Переходим в режим fastboot и подключаем к пк (POWER + VOLUMN DOWN)

2. Загружаем загрузчик lk2nd.img в ОЗУ

[!] Если вы пропускаете этот шаг и сразу загружаете/прошиваете обновленный загрузчик lk2nd-update.img, то вы не сможете прошить boot.img!

3. Прошиваем boot.img в раздел boot

4. Прошиваем обновленный загрузчик с модифицией под ваш сенсор lk2nd-update.img в раздел lk2nd и перезагружаемся в него

5. Прошиваем образ с ситемой userdata.img в раздел userdata и перезагружаемся

Решение ошибки "mdtp image is corrupted" и бутлупа в fastboot

После шага "Прошивка (5 пункт)" есть большая вероятность, что вы получите бутлуп в fastboot, а при попытке загрузить загрузчик lk2nd в ОЗУ ошибку "mdtp image is corrupted"

В чем же проблема?

Дело в том, что когда вы прошиваете обновленный загрузчик lk2nd-update.img у вам меняется активный слот на B (а в слоте B у нас ничего нету).

Просто поменяйте активный слот обратно на A в режиме fastboot и перезагрузитесь.

Hey o/ Thanks for sharing ur knowlege. I'm stuck with pmbootstrap scripts for a couple days and never got it to work. The closer I got was using fastboot commands, but I can't get the touchscreen to work.

And then I found your guide and saw something I was doing different:

[!] If you skip this step and directly flash the updated loader lk2nd-updated.img, you won't be able to flash the boot.img!

I was flashing the boot img before loading lk2nd into ram or was not flashing the boot img at all.
So I tried your way, but the touch doest not work on none too. I was trying with phosh.

Now I tried with sxmo -- with goodix touch does not work and with edt the rom does not boot.

I flashed the stock rom using mi flash, but think it's not the latest. It's pretty hard to find those roms lately.
May u have some idea of what I have to do?

THX!

As i understand you have touchscreen edt? I can make a build again for edt, maybe I made a mistake

Follow here, I'm sure you just need to flash a modified lk2nd to get the touchscreen to work - progzone122/lk2nd-xiaomi-daisy-sakura-prebuild#1

Thanks for answering!

I'm not sure what touch I have. When in lk2nd bootloader, I can see qcom,mdss_dsi_ili7807_fhdplus_video in panel line. Is this a good info?
But I don't think it's a issue with your pre-built version, because I can use both with phosh (even if I can't get touch working with none).
