[Q] SCH-i800 fail to mount error

Hi guys, received a VZW sch-i800 from a friend and trying to get it to work. Any relevant searches have led me here, but no suggestions I've seen have worked so far. Tab is stuck in boot loop. I've flashed it with odin and heimdall (versions 1.1 to 1.3.2) with various files suggested, but everytime I get back into recovery mode and attempt to do a factory restore I get the following:
--Wiping data...
Formatting /data
E:format_volume: rfs format failed on /dev/block/mmcblk0p2
Formatting /dbdata...
Formatting /cache...
E:format_volume: rfs format failed on /dev/block/mmcblk0p1
Data wipe complete.
E:failed to mount /preload (no such file or directory)
E:install_application_for_customer: Can't mount /preload
your storage not prepared yet, please use UI menu for format and reboot actions
and then a line of code telling me it can't mount cache.
I was able to get CWM recovery and the device would give me a different menu, but still the same issue with mounting cache. The instructions on CWM mentioned running a zip program from the sdcard, but no zip showed up in the directory when I looked on the device.
Any help greatly appreciated.

I have the same issue you reference. Did you ever figure out how to fix this? Thanks

I'm also having the same issue with my SCH-i800 after getting CM9.1 up and running. I'm thinking (hoping) it could have something to do with me updating CWM through Google Play (from v5.0.2.7 to v6.0.2).

got sch-i800 broke from someone we know

Lg Optimus 4x HD Won't boot, System error, no mount

Ive had this phone for a month as a backup and I rooted it perfectly. Now for some reason it just stopped working. When I turn it on, it shows

-wipe data/factory reset
-wipe cache partition
-apply update from cache
-wipe nv partition
-toggle console VART Log
None of these work and I cant even factory reset.
On the start up, below it shows the Prompt

PLEASE HELP ME

How did you manage to get your phone in that state? But seriously, what did you do after rooting your phone that could cause this?
Bad thing you rooted your phone but didn't install CWM, you could recover a nandroid backup but, somethings weird here, "can't write NV partition" some people say restoring a nandroid backup fixed their issue.
Does your phone write this "E:can't write NV Partition." itself or did you choose option "Wipe NV partition" ?
As far as I know, NV partition contains IMEI etc., if the files are corrupted in there, theres nothing much you can do.
Try wiping cache partition, shouldn't be any danger in doing that, perhaps factory reset too but I don't think this'll fix your NV partition, you'll probably need to get your phone repaired and its rooted so your warranty is now void.
This problem is common among SGS3 & samsung users, but they usually can boot their phones, but can't access network.They r using some programs to re-flash their original files, they wouldn't work on our phones though.
I'm used to get such errors on my old phone. (not NV partition though cause I didn't touch it ever) These errors were usually due to using ext4 filesystem on kernels that didn't support ext4, so I guess your partitions are corrupt and your phone can't format them, did your phone sustain any physical damage lately?
Cache partition is supposed to be corrupted over time and formatted by system whenever that happens, It's easy to corrupt it but the problem with your phone is that it can't format it.
Try getting your cache partition working, perhaps you can still boot with your IMEI etc. corrupted and rescue your phone.
Try that 'KDZ firmware flash' method, most people use it to update their firmware versions but seen some people using it for unbricking their devices, however I didn't use anything other than LG pc suite so I don't know how you'd exactly do that.
It could also be that CAC file "/dev/block/platform/sdhci-tegra.3/by-name/CAC" corrupted, I don't know what that file does but it sure does have a role while formatting /cache, so firmware flashing may help with that
I'm not an expert, these are the only methods I have in my mind, good luck mate

there was none from the start. and I didnt do anything. I was just texting people.
Also do you have a skype? i need your help|

Hi,
First of all what important is that you keep yourself cool. Read first and understand it then take any step.
http://forum.xda-developers.com/showthread.php?t=2179126
Try the above given link if you can reboot into software update mode.
Otherwise you can try the instruction from @RuedasLocas in Post 7.
But as far I think LG Flash Tool should do the trick for you.
Hope you will be able to do it.
All the best.

TF701T partitions appear corrupted...HELP?

I stopped using my ASUS tablet a couple of years ago when internal memory started giving me trouble, but recently I started messing around with it again to see if I could get it working again. It appears that all partitions have no free space so that i cannot install a custom rom, fix anything, or really do anything. If I go to fastboot and try to force install a new recovery or new rom or anything it looks like it works but it really doesn't. if I try to boot, I just go in a boot loop.
I got twrp to boot(can't get it to install) and it tells me when I try to fix the partitions that they have 0 space?
Anyone have a tool or know the steps to delete and recreate ALL the partitions for the TF701t(K00C)? Any help would be appreciated.
I've tried twrp fix partitions, I've tried it's resizing as well. I've tried to install a stock rom, hoping it would rewrite them. nothing works.
Worse case is it possible to convince the tablet to just use an SD card as the internal storage and not use the emmc at all?

twrp cannot access/read data partition because it's encrypted. while in TWRP, you have to format the data partition to remove encryption and then you be able to access data. be sure to backup your data/internal storage before formatting, otherwise you'll lose what's stored there it's mentioned in most (if not all) TWRP threads related to Samsung devices.

thanks for the info I actually googled and found the answer however ,I do have another question the no-verity-opt-encrypt-5.1.zip is just for whatever rom you have installed to remove the encryption ?In otherwords if i just want to do a clean install from TWRP and install a custom rom I dont need no-verity-opt-encrypt-5.1.zip ?

A problem with installing any ROM - unable to wipe or mount /vendor and /product

I have a problem with my phone ... Recently I unlocked the bootloader, installed TWRP and moonlight rom. Everything worked the first time. Something fooled me and I formatted the phone through fastboot, I wanted to re-install the system and from now on worse ... started with hanging off at startup, so I made a "wipe" of everything again and again, later attempt to restore the backup from recovery, although it went but without half of the application (? by the way I have no idea how or why?). So it could not be so I started again ... later I read on the internet about the change of the file system and started to combine to switch from f2fs to ext4 and vice versa. In the end I did not know what were the default systems and the phone does not boot at all: /
I noticed that now when I try to install anything, wipe or whatever jumps in TWRP error:
Unable to wipe Vendor.
Unable to wipe /vendor.
Updating partition details ...
Failed to mount '/vendor' (Invalid argument)
Failed to mount '/product' (Invalid argument)
I do not know whether this should be so but you can not mount these partitions in menu and in the "Change file system" /vendor has 0MB.
I will also add that I tried to install using three buttons (VOL UP + DOWN + POWER) and the firmware on the SD card update.zip but at 5% crashes with the message of failure.
I have no idea what I can do right now, what actually happened and why, so I am asking for help in solving or at least clarifying the matter.
I apologize for the language but I can not speak English very well and I used Google Translate.
Thank you in advance and best regards
