Please help - Samsung Galaxy Y Bootloop and not recognized

I am having the same problem as in this thread:
https://forum.xda-developers.com/showthread.php?t=2371548
The phone is stuck in a bootloop and is unable to mount /data.
But when I attach an USB cable, Windows says: "one of the usb devices attached to this computer has malfunctioned and windows doesn't recognize it"
I tried this on 3 different computers with Windows 10 and they all say the same.
I did everything: Another usb cable, usb port, drivers delete and uninstall and reinstall, samsung kies install and uninstall, but nothing works.
The phone is charging and sometimes it is vibrating, but other than that it does nothing. I tried to manually mount data, format data, flash a custom Rom, and everything by SD card, but nothing works and it keeps getting stuck on bootloop. The problem is I can't use Odin to flash the files manually, so how do I flash the files from http://d-h.st/PF5 with a SD card only?
Please help!
Edit:
Flashed CWM and stock ROM with SD card - but it says 'unable to mount /data' and it's still stuck in a bootloop
Windows says in device manager: device descriptor request failed
I tried flashing the files in http://d-h.st/PF5 with SD card, but that didn't work? Can anyone help me?

[HELP] Soft bricked smartphone

Hi everyone,
For some stupid reason a reset the file system i now I'm stuck in the LG logo.
1. I can enter in download mode - in Device manager the PC recognized as LGE AndroidNet USB Serial Port (41)
2. I can enter in recovery mode (Cyanogenmod recovery, which is very based) - in Device manager the PC recognized as Android ADB Interface
So far, so good. BUT. I'tried to flash the phone with LG FlashTool 2014 and i'm stuck at 2%. Ok, i was tried the fix with FixedDownloadcmode.bat, but when nothing is uploading on the phone (which by ADB is recognized as sideload when i'm in recovery mode and apply the ADB connection). I tried to push by ADB but nothing is uploading - error: protocol.......
LGUP recognized my phone as unknown, so this method is not working now.
Via ADB i can't send even TWRP recovery, which is so much flexible than cyanogenmod recovery.
I will be thankful for any help from your side.
Thank you in advance!

I had a very similar problem with it getting stuck at the logo after pushing supersu to the phone. I followed Supersport every single step of the way in his video. I think his links are the only valid ones online now, so just download them and reflash your phone. If your G2 is anything like mine, drivers will never appear to be installed correctly and it never restarts, only shuts down.
His method is:
1) Download and install LG drivers on PC
2) Download and install the flash tool and patch it
3) Download and load the .tot and .dll files into the flash tool
4) Enter download mode on G2 by holding volume up while connecting USB
5) Switch G2 Com port to 41 in device manager
6) Once Flash tool shows that all ports are ready, power down G2 and disconnect
7) Hold volume up and reconnect to get back into download mode
8) LG Flash tool starts flashing
9) Complete
Note: If your G2 was screwed up as bad as mine, it'll say failed but all the main system files will load to the device before it restarts and it'll even shut itself off while doing it's installation on first reboot. Mine somehow was still revived from this state with his method.

I forgot to add this but couldn't edit my post for some reason.

[HELP] MI A1 Failed to load BCB message, failed to fsync (operation not permitted).

Yesterday suddenly while turning on my device it stuck at android one logo.
Device status : Bootloader locked, No Root. Never hard reset in past. it was running as it was out of the box with latest May 2020 security update.
So, i tried to unlock bootloader with adb which offcourse failed.
then i tried to hard reset, as i opened recovery mode (power + vol+) there was an error E: failed to load bcb message, failed to fsync : operation not permitted.
still i choose wipedata/factory reset. it stuck at [wiping data... formatting disk...] for 5 hours. i understood it wont proceed.
Then, i opened the device went to unlock bootloader with EDL method as shown in few videos ( by connecting pins and plugging usb to pc). it showed in the pc ( qualcomm was listed in device manager> ports)
Then i downloaded Mi flash and official rom, was unable to flash with error "ack count don't match".
Again reading here and there, i downloaded miflash-beta, it was able to flash the device successfully.
disconnected the usb, connected the battery strap and started device > Again it stuck at android one screen for 1 hour.
So, i again went to recovery mode to find out that the error " E: failed to load bcb message, failed to fsync : operation not permitted." Still exists.
Read here in some thread that it is related to partition damaged, but no solution anywhere.
Please help me with solution. This is my only phone. i don't have any job nor money to buy other phone during lockdown.
HELP.
Thanks everyone for this wonderful forum.
