[Question/Tutorial] Make a phone unusable in 4 simple steps

[RenzoMag]

Hello!.

I'm going to show you how to make any phone unusable, like I did with my Sony experia m4 aqua!
Step 1: Unlock the bootloader.
Step 2: Install a corrupt custom rom.
Step 3: To mess things up even more, go to your twrp recovery and wipe everything (even internal memory!).
Step 4: Enjoy your new expensive paperweight!

Well, beyond the joke, yes, that's what I did, without any kind of wisdom I tried to install a custom rom and the only thing I achieved is a completely useless phone which to this day I cannot recover with my knowledge, if you You know more than me (surely you do), you can read my great problem and hopefully know the answer.

Post about my problem:

Hard brick / Device not found. Sony M4 Aqua E2303.

I installed a faulty ROM which caused my phone to not be detected by my computer (it shows up as an unknown device). I want to flash the original rom, but there is no way, because when I do it with the flashtool and it asks me to connect the...

My last chance, the sd.

Hello, first of all sorry for the English (google translator). I will start from the beginning of all my problems. My phone, Sony Xperia m4 aqua e2023, began to have problems with the original rom, so I thought of restoring it with the twrp...

I'm no pros, but as far as I know, your phone can still access TWRP and can still read sd card. Why don't you try flashing a rom by sd card?

Much simple and dangerous:
adb reboot bootloader
"unlock bootloader"
fastboot erase abl
fastboot -w
fastboot reboot

Not really, I can't access twrp, because I inadvertently wiped the internal storage, next to that was twrp, so I don't have a custom recovery, not even the stock one.

And what does that really achieve?

Delete bootloader, the phone then can't boot into anything

Damn, and in case someone does that, will there be any solution? I already think about some management in the hardware

Only solution is to boot into fastboot using testpoint or desoldering emmc and flashing with a flasher

I think that is one of the only solutions I have, since my computer does not recognize my phone, and I also have no way to enter a custom recovery.
I investigated some of the test point, but I don't know if my device supports it and if there is someone in my city who wants or has the tools to do it, I was directly thinking of changing the mother for a broken screen phone, but there isn't even that. .
In this post I talk about that, but do not clarify any doubts

Yes, by the way I would go flashing emmc directly since you have no istructions to use testpoint

From what I understand, that is done with special tools, right?
