I have a rooted desire which was s-off. I have installed a few custom roms and have not had any problems. On my latest rom, Leedroid 3.0.8.2 i was preforming a nandroid backup and when my phone restarted it went into bootloop.

In recovery an error came up, E:can't mount/dev/block/mmcb1k0p1( No such file or directory.Error mounting SDCard!

My SD card works in other devises and I have tried everything, even reformatting the card.
In my bootloader it says
Bravo PVT1 SHIP S-ON
HBOOT-0.93.0001
MICROP-031d
TOUCH PANEL-SYNT0101
RADIO-5.09.00.20

I have no idea how I S-ONed my phone, but now my superuser applications will not work. PLEASE HELP!!
Can't read my SDcard or perform any functions like AlphaRev to gain S-off again.

 

I am sure my phone was s-off. I bought my phone in China because I am living here for the next few years. It is a real phone, made sure of that. I have installed a custom roms before.
I will never use rom manager again because it has already screwed up my phone once.
this time I did a backup in recovery mode so I could install a new rom, (I want one with sense 2.1) and when I rebooted my phone, it went into a bootloop. Constantly loading the Leedroid start up screen over and over again.
I then went into recovery again to flash to my older backup, but kept getting that error message about being unable to mount sdcard.
I went to my bootloader screen and it now says s-on. I am stumped. I will look into usb brick and get back to you all if that doesn't work.
Thanks for the fast reply. I am really scared about going to a Chinese phone shop and having them try to fix my phone
