[Q] Error when attempting to use TWRP for Backup - Transformer TF300T Q&A, Help & Troubleshooting

Hi, I was hoping someone could help me with a problem when attempting to perform a backup. I upgraded to the OTA Jellybean 4.2.1 stock ROM and installed TWRP. However, when I attempt to do a backup I get an error:
E:failed to mount /data (No such file or directory)
-- Could not mount: /sdcard
-- Aborting
Has anyone experienced this before? Is there a way to fix this issue? Does the SD card need to be in a particular format? Right now it is in NTFS. It's a 64GB micro SD card. Thanks!

I actually figured it out. The version of TWRP was too new. I installed an older version that was posted by Flumpster in another thread and it fixed my issue. Thanks!

Error meesage: failed to mount sdcard

Under the development section I want to use the [ROM/UPDATE] Android Honeycomb 3.2.2 - Stock & Rooted.
I am trying to apply the zipfile through android recovery and I keep getting the same message...
E:failed to mount /sdcard (No such file or directory)
I have used a couple of different Micro SD cards. The cards mount and work fine normally.
Any suggestions

Do you have ClockworkMod Recovery installed? If so what version? They don't all read the external sdcard.

[Q] E:Unable to mount '/external_sdcard

I'm using TWRP 2.3.1.0 to try and install a .zip file (the new JB version), using the Install feature. The situation I'm running into is that on both internal and external_sdcard my .zip file is not visible. I cannot mount the external sdcard, when I use the mount feature the TWRP log shows many E:unable to mount "/external_sdcard errors. Even on internal storage I can just see the folders and no individual files let alone the .zip file. When I boot into my currently installed ICS 9.4.5.30 version I can see all my files no problem including the .zip files.
I"m confused because I successfully used this very same process to upgrade to ICS 9.4.5.30 from .26 with no problem back in Sept.
I've searched and googled but so far nothing has added to my understanding off what is wrong or what to do at this point.
Please help if you can, thanks in advance.
I've found my .zip file!...under the internal directory /data/media (not sure why this file only appears under this directory). I've updated to JB from that .zip using the TWRP Install and it all looks good. Still don't understand why the file could not be found under the internal /sdcard directory nor the /external_sdcard with TWRP. Perhaps my misunderstanding of how TWRP works perhaps some problem with TWRP 2.3.x.
So I guess nothing more required.

Can't install .zip file from CWM

I am relatively new to the world of rooting and ROMs, but I have successfully installed CM10 on a previous Samsung phone, so I am decently literate.
I am currently attempting to install CM10.1 on my Verizon Galaxy S III (following the instructions on the Install CM for d2vzw page on the CM wiki), but I have reached an impasse at step 7. I was not aware that I had to put the VRALE6.bootloader.zip file on the SD card before starting this process, so I am now attempting to get that file onto my SD card either by sideloading through CWM or by pushing it to the SD card through adb. The issue is that CWM gives me an error (can't mount SD card) and adb doesn't recognize my device (I have tried installing and reinstalling various drivers for the past few hours). I enabled USB Debugging mode before starting the process, but I am only able to get into Download and CWM modes right now (if I don't do the Download Mode or Recovery Mode key combination, I am stuck on the Galaxy S III screen). Am I bricked at this point, or is there a way to get VRALE6.bootloader.zip onto my phone and continue with the ROM process?
It is important to note that I formatted the SD card before starting this process because I wanted enough space to put the Cyanogenmod file on it. However, I think I may have formatted it generically rather than into FAT-32. Could this be the issue?
I am going to pick up a microSD card reader today in order to flash the SD card to FAT-32 and put the CyanogenMod file on it.
I am getting 5 errors upon startup of CWM (E: Can't mount /cache/recovery/command, can't mount /cache/recovery/log, etc.). When I try to mount the SD card or external SD card, I get E: Can't mount /sdcard/
Same issue with sd card not mounting.
I'm having somewhat of the same issue. I've tried both Clockwork recovery and TWRP and have the same issue.
Should have mentioned that i still have access to the stock rom and can use my phone just fine.
I some how got Clockwork mod recovery to work using the Rom Manager pro App.
I wish i had been paying better attention to what i was doing but i know i updated CWMrecovery from in rom manager and chose to install my chosen rom with that.
My suggestion is to start over completely. There is a much easier way to do this.
My suggestion is to flash one of the rooted stock ROMs through Odin. There's a thread in android development that has rooted stock. Then when that's done boot up your phone. If it bootloops wipe data. Then use Ez-Unlock 1.2 app to unlock your bootloader. Make sure it's 1.2. Now use GooManager to flash TWRP. You are done! This is probably the easiest way to do this.

I am not familiar with TWRP, so is the process the same for flashing CM (putting CM zip file on sd card and going to install from SD card in TWRP)? Are there any additional steps beyond this?
I am following the directions in the thread linked above to root and install TWRP. So far, I have the rooted stock ROM running fine, but I can't get TWRP to work. I downloaded Goomanager and attempted to get TWRP using the Install Openrecovery Script option. However, it said that it couldn't find a recovery for my device. I also tried to use the adb method, but nothing happened after I put in the commands. I even tried to flash the latest TWRP .tar file from their website using Odin, but it keeps failing. Is there any way to get TWRP on my phone?
EDIT:Whoops, I skipped over the EZ-Unlock step. Now everything works. Thanks for the help, Sandman!

Alright, maybe I'm not quite fixed up yet. I have TWRP installed and I can go between TWRP, download mode, and the normal stock rooted ROM fine. However, I cannot get to the SD Card in TWRP in order to install CM. TWRP gives me the following errors upon booting into recovery:
E: Unable to find parition size for '/boot'
E: Unable to find parition size for '/data'
E: Unable to find parition size for '/recovery'
Updating partition details:
E: Unable to mount '/system'
E: Unable to mount '/cache'
E: Unable to mount '/cache'
E: TWFunc: :Copy_Log - - Can't open destination log
E: Unable to mount '/cache'
Upon trying to go to Install, I am unable to select the external SD card, and an additional error appears when I attempt to touch Micro SD Card (E: Unable to mount '/external_sd').
I guess I could try to sideload the CM zip file through adb, but I would rather fix the SD card for future use. I have been researching and working on the SD card for the better part of today, to no avail. I am pretty sure the issue is in the formatting of the SD card (it appears to be RAW rather than the required FAT32 for CM), but I cannot format the SD card into FAT-32 no matter what I try (both Windows and 3rd party formatting tools). They all say that the SD card is either write-protected (I have already checked the read/write switch on the side of the SD card adapter) and/or the format cannot be completed. I have tried both my old SD card that I have kept for a few phones (an 8GB Samsung microSD card) and a brand new Sandisk 8GB microSD card, both of which will not work.
I am able to transfer files to the SD card with no issue (with both ADB and through dragging/dropping in Windows), but I cannot install from SD in recovery.
Does anyone have a solution to allow me to install CM on my phone?

Yes, I do have root access. I think the problem lies somewhere in my SD card.

Do you have another computer to try formatting the sdcard with? And you said that you receive the same errors when trying to reformat the new 8 GB sdcard as with your other sdcard which is formatted to RAW?

I do have access to another computer, but I ran out of time and patience yesterday. I will try it when I get home later today. And yes, both cards are RAW (even the new one) and I can't get either one to format or work in TWRP.
So it appears the the issue with formatting was due to my computer's drivers (even though I installed the latest Samsung USB drivers) and not the SD card. I was able to format the SD card to FAT32 on another computer and put CM and GAPPS onto it. When booted normally into TouchWiz, the phone sees the SD card fine. However, I still get the same "Can't mount external SD card" error as well as the others previously listed when I attempt to install a zip from recovery. I even tried to sideload the ROM from ADB, but it still didn't work.

Which version of CWM and also TWRP are you using?
And the problems keep rolling in. I was able to mount my SD card and get rid of the TWRP errors by installing a modded TWRP 2.6.0.0 from this thread (http://forum.xda-developers.com/showthread.php?p=44277901). However, when I go to install CM (cm-10.1.3-d2vzw.zip), I get the following error:
assert failed: getprop("ro.product.device") ==
E: Error executing updater binary in zip '/external_sd/cm-10.1.3-d2vzw.zip'
Error flashing zip '/external_sd/cm-10.1.3-d2vzw.zip'
Updating partition details
I did a factory reset before attempting to install this, but I did not format data or do anything else.

Well, that is for the Sprint S3 my friend. We can't interchange recoveries between the different S3 models to flash roms. You may want to ask Kennyglass123 or any of those other guys if they can make a change for the VZW S3 for you to test it out.

Sounds good. I think the problem has been isolated to being something with needing a modded TWRP. I tried using an older, non-modded TWRP (2.5.0.0), which didn't work.

Would you mind trying this soft brick fix? If I'm not mistaken, I believe you're experiencing this same issue--excluding the Sprint TWRP issue you just mentioned. You will need to flash your VZW custom recovery either through GooManager, Rom Manager, or Odin btw.

I can still get between the stock rooted ROM, download mode, and recovery mode fine, so does that mean I am still soft-bricked and should try this?

This soft brick fix is an attempt to correct the /system and /data errors.

TWRP 2.6.1 won't mount file system

Has anyone experienced issues with TWRP being unable to mount the file system?
I can't seem to mount file system while in the recovery. Get the following:
E: Unable to mount 'external_sdcard'
TWRP can't deal with NTFS or exFAT. Is it fat32?

What I meant was, that your external MicroSD may be formatted in NTFS or exFAT and then TWRP won't see it. It has to be FAT32. If you ever formatted that card on your PC, that may be the problem. If not, the card could be faulty??? IDK
I assume you went to 'Mount' in TWRP and the MicroSD is not checked?
Describe a little more what you are trying to do.

Nope - I don't have a MicroSD card. I was just trying to mount the data on the tablet. My initial post wasn't clear - I was try to mount the file system on the tablet and the only error generated was specific to mounting the sdcard (which I don't have).
I couldn't have titled the original post any worse.

BUT I'm facing this bugs:
#No internal storage at all (It says 0 and can't install google play apps because it says that I have no free space)
#Reboot erase all config and apps installed. It takes the phone like it recently flashed the rom.
#EFS is missing (Have backup, restored, but the problem above makes all difficult)
I'm thinking that the /device files might be corrrupted. But I don't know how to solve this.

It looks like that the eMMC is not working, /sdcard and /data are on it.
I don't think the problem is due to the fact that you wrongly flashed the files. As long as you don't mess with bootloaders, things can most of the time be fixed.
It looks like an hardware failure, but I could be wrong. I've no ways to determine it.
Anyway, the eMMC is not the most important memory in our device, you can replace it with the external SD. There are several ways to do it, some users posted their solution here in the forum, this for example.

Yeah, I'm starting to think that.
I will try to swap SDs.
But I have a question. My main problem is that most of ROMS don't boot. Don't know why, but the only ROMs I managed to boot are CM7 and MIUI 2.3 also. Why this? If I try a different rom it gets stuck in bootloop or doesn't even install it at all.
If a swap sd would this limitation of roms will be solved? I mean, this swapping is permanent or it goes away every time I flash a new build????

I can't explain why CM7 is working, there could be several reasons (/cache is inside the OneNAND, it's using your SD card for /data etc...).
The changes for the swap are usually in the kernel ramdisk or /system and both of them are entirerly wiped during ROM updates, so you should do them on every ROM update.
