Раньше, когда я пытался распаковать с помощью сторонней утилиты она жаловалась на отсуствие рамдиска, но когда ссылка вела на сайт с этой утилитой у меня получилось пропатчить своё ядро

Модель телефона: Redmi 8a

How to Patch my boot img?

Hi,

I am using Redmi 8A (olivelite) device. I want to root my device, for which I need to patch my rom's boot image.

But in a video tutorial shown here, to patch boot image, we need to use this site and do like that.

But now the link is redirecting to this github and I don't have idea how to do that.

Please help.

usage confusing need more guide (and also facing many strange bugs?...)

I tried to run it on my PC(win10) but failed...

C:\Users\rightester\Desktop\temp>py
Python 3.9.1 (tags/v3.9.1:1e5d33e, Dec  7 2020, 17:08:21) [MSC v.1927 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> exit()

                                                     ^
SyntaxError: invalid syntax

So I once tried to delete all the "f" before the string and it can run but will exit with low version warning

C:\Users\rightester\Desktop\temp>py main.py boot.img
ERROR: Python version too old. at least 3.9.0

(Oh no this is so weird, I just install the py 3.9.1 for this warning but it's still not working...)(actually 3.7.5 won't raise SyntaxError (?) (maybe it require only 3.9.0?)

Anyway, I annotated(#) that line, added a line "pass", and tried to run it again, and...

C:\Users\rightester\Desktop\temp>py main.py boot.img
ERROR: Can't found IMG magic number

oh...
the tested two boot.img files are Redmi7A MIUI global version and CN version, so maybe not the version's problem
I have no idea if I have properly settled down the environment

Can any more detailed guide or tutorial be added to this project for more easily getting started ?

I browse this repo because the redirect of the link patcher.yaalex.tk , thanks for this website I got my Redmi7A rooted. but there are other guys asking for the method to root and stuck on the step packing the boot img...

Sorry for disturbing, thanks for glancing, hope to be replyed soon(
