cannot mount or reformat internal sd card
hello everyone! first time posting on xda. i've researched everywhere, and yall are my last resort. here it goes........
sprint 4g lte, rooted, s-off, cm10.
somewhere in the processes of rooting and turning s-off, i lost my internal sdcard. can't mount it or reformat it.
my first indicatation something was messed up was when i tried to download a new rom, the phone gave me a message saying "cannot download without a valid sdcard." but i had a 32gb sdcard in it... also when the phone booted up it said something like "process.android.phone has failed." and when i tried to connect my phone as mass storage on my win7 32 bit pc, it wouldn't ever see the sdcard. not even the 32gb external.
i figured it was the jelly bean (or something like that) rom i tried first after rooting. maybe the zip was corrupted or something. i took out my 32gb sd, hooked it up to my computer, downloaded cm10 and gapps, then put it back into my phone, wiped everything and flashed.
that's when i discovered all the errors listed above.
so i figured i would try to do a factory reset. when i try to wipe data/factory rest through cwm recovery, this is what it says... E:format_volume: make_extf4fs failed on /dev/block/mmcblk1p2
i've read about people getting twrp, booting into it, mouting the internal to the pc and reformatting that way. but how can i do that without the internal sd? the same way i got cm10 and gapps?
so all in all i'm pretty lost and pissed off. i'm somewhat droid savvy after having an evo 4g. but this a new beast..... please help!!!
let me know if yall need any more info. thanks in advance!
EDIT: FIXED!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! !
i was finally about to flash twrp recovery and dumlock through twrp. i then mounted my internal storage via "mount usb storage." my computer recognized the drive and formatted it! mounted and working great!!
