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 ?

[Q] Having some Big problems on my motorola razr i! please help.

Hey guys.
So i have this razr i with TWRP 2.8.0.0 recovery installed on my phone and my bootloader is unlocked. I have installed several diferent roms on it over time, and this time i tried to install the unofficial Cyanogenmod 11 (http://forum.xda-developers.com/razr-i/development/rom-unofficial-cyanogenmod-11-t2966855) but things went totally wrong when i formated the phone on recovery.
Here's what i did:
1- booted into recovery
2- went to the "wipe" tab
3- taped on "advanced wipe" and selected eveything (Dalvik cache/System/Cache/Data/Internal storage/Micro SDcard), then started formatting
4- after about an hour and a half it was still checking for md5... so i rebooted
5- when i rebooted i realized that everything was gone, including the rom files on the sdcard, so i passed the files from my pc again and tried to install but nothing happend.
6- now for unkown reasons all i see is:
Code:
E: Unable to mount '/data'
E: unable to recreate /data/media folder.
Updating partition details...
E: unable to mount '/data'
E: unable to mount internal storage.
E: unable to mount /data/media during GUI startup
FUll SElinux support is present.
E: unable to mount /data/media/TWRP/.twrps when trying to read settings file
E: unable to mount '/data'
MTP Enabled
So... My PC has the motorola drivers installed and i've also tried on mac (i have a Macbook pro with widows and mac os), but none of the recognize my phone so i can't use adb or anything that could help with this.
Does anyone know what to do? I just want to install stock jellybean again and then try the cm11 rom.

Can you boot into recovery? maybe you can try adb sideload.

Yes i can, bootloader and recovery, but as i said my phone isn't recognized so adb sideload does not work.
I tried using mac because i read somewhere that you don't need drivers on there, but it didn't work either... unless i'm doing something wrong

I've experienced with similar situation getting no adb in TWRP. However, when I chose Advanced/Adb sideload, adb sideload did work for me.
PS: Maybe you can try install aother recovery.
Hey! Apparently, your phone has now all the partitions corrupt, because of that failed format. Have you tried installing a stock ROM through RSD Lite?
I once had a similar issue, solved it with a clean SBF flash.
Also, to install a new ROM, you should:
1.Boot in TWRP
2.Go to 'Settings'
3.Check 'Use rm -rf instead of formatting.'
Then, the wiping process wont take more than a couple of seconds, and should install ROM's without problems.
Hope you solve it, and sorry for my english if I made any mistakes.

Have u read the install instructions? The instructions stated that u needed to use the latest recoverys and u still use the 2.8.0.0 one.
The earlier versions have problems on some phones like the one u have now. Some do have the problem some don't. U can fix it by erasing the userdata through fastboot hopefully or by installing touchcwm (the earliest of recoverys for this device) and formatting it that way. Most of the time this fixes the problem.

i tried what you said but i still get this problem:
Code:
E; Unable to mount '/data'
E: unable to mount internal storage.
EDIT:
By the way, how do you do an SBF flash?
You have to download one from your region. You can make it to the fastboot menu? And it doesn't detect the phone?

Help twrp vtr-al00 failed to mount data cache and system

Unable to storage
My device is locked storage
Sd card is still displayed
Now I don't know what to do
I Need help from everyone

Up help me
What you want to do?
Maybe you need a different twrp?
You can go back to stock using this guide tool.
https://forum.xda-developers.com/mate-9/how-to/guide-mate-9-flash-update-package-t3593108/page68
I also tried but still failed.
twrp failed to mount "data" "system" and so on.
I cannot backup or wipe any thing in twrp.
I also try to rebrand my VTR-AL00, but
It doesn't work.
I think there is a limitation in Chinese edition P10.
I even cannot install zip files in twrp and I flash a modified rom to root , using fastboot

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?

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

Problems with installing on a samsung S7 (930f)

Hey - so far I've used odin to add twrp, and I've gotten to installing the zip - when i try install it, it works through the list, unmounts partitions, then says 'Done'. After that it says 'Updating partition details...' before failing with the message 'Failed to mount '/data' (Invalid argument'. I've tried wiping the cache/dalvik, but that still does the same thing. any fixes/things I should try? Any help would be appreciated as when i reboot, my phone now says - Verification Failed, and the reset option just takes me to twrp recovery and does nothing
