Question A22 5G A226G Bricked, Can Brom/Bypass. Can't find correct firmware

[Decmanager]

I messed it up, I'm sure I flashed sp tool with just preloader All format + download by accident.

Now can't recover, I can bypass auth and connect on Brom and flash but mainly arrive at role back error or not signed etc.

I've done filter on com / mtk driver etc.
Authentication bypass all goes fine.

All firmwares I see are for A226B etc but no A226G, I've tried to flash many FW without much success. I'm not sure what I'm doing anymore and my head hurts (I was pretty new to this a week ago).

I'm sure it was on Android 11 with 3 network but not sure if EU or not etc.

I see something about binary version or patch etc, is there a way I can read what's on there at the minute and find a way to paste that here for someone to help with without much hassle for them?

I know I'm close, just need a path to follow.

Thank you so much

I've tried, doesn't work for me. Which firmware am I supposed to extract, the one originally on my phone or the latest? I've tried many and have no luck. I get "status sec imghdr type mismatch" on most other than "anti role back"

I've tried various FM and I get

"status sec imghdr type mismatch"

What is that normally? It's frustrating, I feel like it's something simple. I've tried different SP tools, different ways to extract firmware like Android utilities and auth tool v30 etc to arrive at the same error.

Download the firmware and see if it works.

3.7 GB file on MEGA

mega.nz

We will then try to flash using paid software Unlock Tool.

Don't worry I won't charge anything.

Transsion tool come up with this error, I also just tried another version which also gave the same outcome.

Are you saying that I need to try other MTK download tools?

What is my ultimate goal

 

[Decmanager]

I found version SWDv4.1901.23.17 opens correctly, I'll try generate a .ini now

 

[Decmanager]

Not working for me, I get this error:

checksum dochecksum fail: unknown target bbchip


I've put about 40 hours into this (I don't mind doing more, I learn lots)

Doing some more investigating on where I went wrong, I noticed a product read out in Android Utilities:


This product points to a Samsung A12?

Possibly why I'm getting errors.....
