Question Did i kill my phone for good...?

[Justanumber9826]

Hello, i've already asked on XDA but no response there so here i am.

What happened:
I unlocked the bootloader, OEM unlock in developer options, also enabled usb debugging.
From my laptop, with odin flashed TWRP recovery with a patched VB meta becuse without patched VB meta the process didn't work.
Then from twrp installed lineageos as system. For few days all was good. Now after not using the phone for a week, i wanted to boot it up but nothing happened.
It was strange, i managed to boot into twrp recovery and decided to reflash the latest lineageos version, but before doing so i decided to wipe everything, literally everything that was available to wipe in twrp, i wiped it all. And formatted data.
Then i wanted to reboot, but now the twrp recovery is gone, did it wipe itself? I cant boot into recovery anymore. I cant boot into system because there is none installed.
What works is only and only booting into downloadmode.
But...... i have tried on two computers already, installing samsung usb drivers, opened odin, but the phone which is in downloadmode and is connected to pc, doesn't show up in odin... I have also tried using different usb ports, no luck.

In downloadmode, the phone says:

RPMB Fuse Set
RPMB Provisioned
Current Binary Custom 0x30E
OEM LOCK OFF (U)
KG STATUS Completed 00
Warranty Void 0x1 0xE03
QUALCOMM SECUREBOOT Enabled
RP SWREV (long number...)
RP SWREV (long number...)
SECURE DOWNLOAD Enabled
SPU 5
HDM STATUS None

I don't get what's wrong but this freaking device doesn't show up on any computer, not even with usb drivers installed.
The only thing left i can do is boot into downloadmode but it appears completely useless.
I would try another usb cable but i have none, the one i have is from IVON not from samsung but i know its not a charging cable, it can do data transfer because i used this cable to flash samsung A33 and that worked fine.
Also the SPU 5, what does it mean? why is it red? It was some white number before, but that changed now.
How do i fix this bricked phone, anybody please help...

Update:

So both pcs keep responding with "usb device not recognized/malfunctioned", and it doesn't show in odin at all.
But i got into twrp now. Don't ask how.
I booted in downloadmode, connected phone to pc, windows said usb device not recognized so i thought myself F* this, then held all buttos (power+volup+voldown) on phone and it turned off while it was still connected to pc. Suddenly it rebooted into twrp.
So i'm in twrp now, sounds good? But twrp has the same functionality level as downloadmode, none.
I connected usb driver with adapter to the phone and inside of twrp selected it, then i went to install and flashed the lineageos.img to system. After that i rebooted to system.
But it just does not work !!! i did it already 3 times now and the phone just keeps rebooting into twrp. It say the flashing was successful but when i boot into system from twrp, it rebootes into twrp.
I'm losing my S*. Really. Drives me nuts. What do i do?? Sorry for the rant but this costs alot of nerves. Something isn't right with this device

I probably screwed up bigtime.
What i did was trying to flash a new LOS version to system but twrp kept saying "file size is larger than something something".
So i thoght if flashing to system doesnt work, i might try flashing to something else. Ofcourse it was dumb doing so without proper knownledge.
But smart as i am, did it anyways... i flashed lineageos to super. super (system) something something...
As a result, the phone is stuck in an eternal bootloop. I tried several key combinations including connecting and disconnecting usb cable from phone and pc.
It's stuck no matter what i do. Really screwed up here. I did make a twrp backup before doing that, but i can't seem to get into twrp neither downloadmode.
What on earth am i going to do now to resolve this mess? Any advice... (other than not being like me and randomly flashing things to partitions their aren't ment for)

As of now i can't even poweroff.

Welcome to AC!
Odin needs to recognize the device,, is this your first time trying to install a custom recovery? Is it the correct one for your device?

Merged all your threads together

Should have let it be once you got into TWRP and wait for help.
Flashing something to a partition it was t designed to go sealed your fate.

If your PC doesn't see it, ODIN doesn't, and you can't get back to TWRP or download mode you're screwed.

That's what I worry about the damage is done

Thanks for getting back to me, so the first problem was about another device and i fixed that already, but my other post that started with "I probably screwed up bigtime." is about another device and this device is infact still in a bootloop after leaving it on all night.

Any tip to break out of the bootloop? Its the samsung galaxy A54.
Is there really nothing i can do like a keycombination to reset it to factory or just get into downloadmode or recovery? I cant seem to get out of the eternal bootloop

Is there a way to completely reset any modern samsung phone?
I went to a phone-repair-shop and spoke to a person there.
He said he will try to fix my device just with softwarte, i showed him that the device is stuck in a bootloop and that i couldnt get into downloadmode, he said its a bad sign when downloadmode is inaccessible and that he might need to physically open up the phone and reset a switch or something. Reset the baseband is what he said if i recall correctly.
Which reminds me how much i hate phone manufacturers for making it near impossible for the average person to open up their phone by themselfes to switch out the battery for example.
I dont want to pay the phone repair shop, i want to fix this myself. But i lack the knonhow.
Can anyone help with that?

You need to form coherent posts.

One post with exactly what phone(s) you're using. What you did, What happened/Went Wrong.

In a legible formated post, one post.
