[Q] I9000B OS doesn't load/ "Failed to mount /data" / Almost bricked

I got a long story here. First i got this Galaxy S TV (GT-I9000B) from a friend who broke it's Android and I thought i could fix it. I could restore from a brick status to a clockwork mod which failed because that CWM was made for I9000 and not mine which is I9000B. Then, I went to sammobile, downloaded everything to factory reset this phone using Odin. It worked, but when i tried to boot, this thing appears:
-- Copying media files...
Successfully copied media files.
-- Deleting files...
E: failed to mount /data (File exists)
E: delete_data_files:Can't mount /data
your storae not prepared yet. please use UI
menu for format and reboot actions.
-- Updating filesystem...
verifying the filesystem. please wait.
already updated filesystem. finished
successfully update filesystem.
-- Wiping cache...
Formatting /cache...
Cache wipe failed.
-- Appling Multi-CSC...
Installing Multi-CSC
Can't access to '/system/csc/ZT0/system/'.
Successfully applied multi-CSC.
And beside this, the boot is stucked. It can't load anything. I tried using Heimdall to fix but some error (ERROR: Failed to access device. libusb error: -12) shows up, ADB can't access the phone. I also tried learn how to format the internal SD, go through every single error and fix each one but i got lost again and now i don't know what can i do.

Yeah, that is the one that i did. And the results were the ones that i told.
I mean. This one fixed but was incompatible. Somehow this I9000 and I9000B differences affect everything.

My Redmi 4x Is Bootlooping and TWRP Won't Start

So I have this problem. When I tried to flash clarity kernel for my device, it won't boot, but I still able to access TWRP and then I try to Format Data so I can restore my backup later.
But, my device suddenly turned off while it was formatting and still won't boot.
Worse, when I tried to go to TWRP, it just show some log like "failed to mount data (invalid argument)" and "failed to mount /twrp/twrps (invalid argument)". Though, I still able to access fastboot mode, but I dont know what to do with it.
Could somebody help me please? I'm stuck right now.

Please boot in fastboot mode and run:
fastboot format userdata
fastboot format cache​Then try TWRP again.
