Hello all,
Quick background - my wife's T-Mobile S4 went kaput on our honeymoon last night, but I was at least able to save some of her data. The problem now goes to installing a new ROM on her device.
I have wiped EVERYTHING and formatted the data, but when I install ANY ROM (I've tried multiple), I always get the E: Unable to mount '/data" error. Normally, I would just ODIN the stock tar, then install a custom recovery again and then the ROM, but I only have my work computer for the rest of my honeymoon and I don't have administrative access to run ODIN (you might not think it requires it, but if you're only a standard user then you cannot bypass UAC to run it).
Does anyone have any ideas on how to get this to mount? The phone will not boot past the "Samsung Galaxy S4" screen. I've tried going into TWRP and mounting Data but it will not work.
Any help is greatly appreciated! Please keep in mind that I don't have access to ODIN!

Sounds like a twrp issue. Try grabbing the cwm flash able zip and adb push to the sd card and then use twrp to install it. I've read so many issues about twrp. I recommend staying away from it. Philz touch recovery is really awesome too.

Hello! I actually downloaded Philz touch recovery in both .zip and in .md5, so that is what I intend to go with. The issue is how I push it using adb, as I believe I need to install something in order to do so, but I don't have any administrative privileges! This is what's preventing me from running ODIN in the first place!
Can you confirm that I can push using adb without installing anything?
Thank you! - Taxmaster
I had this issue. Odin flashing and then booting into "STOCK RECOVERY" after flashing and then a factory reset in the stock recovery followed by a fresh re-flash from Odin worked to get my phone back up and running again.
I don't know how you are going to be able to fix it by just flashing a recovery. I tried for hours and could not get it to boot from just recovery alone.

What you noted would be my plan if I had admin rights to my computer, but since I cannot get ODIN, I'm screwed at the moment. I'm hoping someone can assist with the "adb" proposal, however I'm not sure one can download/run adb without installation or prompt from UAC

I don't believe admin is required for adb... You could always try it... worst thing that could happen would be nothing.

Using ADB does not require admin privelages, however, if your computer does not have the necessary drivers to detect the device in recovery, then you will have to install the drivers, which then yes UAC is required. HOWEVER, if you have another phone or device that supports MicroSD cards, you can just pop in the MicroSD into a working device and transfer the zip that way, then transfer back the sd card and flash

I did exactly what's noted above --> took out the SDcard, put it in another phone, transferred over the .zip, put it back in her phone, went to TWRP, wiped everything on the device, installed the .zip, and rebooted into recovery from TWRP, and then the new recovery booted! I did another wipe/factory reset and then installed a ROM, but when I hit reboot, it didn't reboot past the Samsung Galaxy S4 splash screen , and to make matters worse, when I go to enter recovery pressing home+up+power, it says "Recovery Booting ...." in the top left corner but it won't boot into recovery!!!
Thoughts?
If someone could strip administrative privileges off of a version of ODIN v3 for me, that would be great! I don't see how else to get around this now!

Out of curiosity, are you flashing a ROM for the T-Mobile S4? If no, are you using a T-Mobile kernel? I only ask because a kernel for a different device will normally cause you to not be able to pass the initial Galaxy S4 screen... Also, as far as TWRP goes, sometimes it doesn't go right into recovery. If it fails to enter recovery after a reasonable amount of time, just hold power to turn it off and try again. I've had to do it 2-3 times at least just to successfully enter TWRP.

I am installing a T-Mobile S4 ROM that uses a custom kernel. The ROM before was the same ROM just a lower revision, same kernel.
With respect to TWRP, I thought it was all gone now that I installed the CWM touch version. I've tried doing it a million times and cannot get back into either TWRP or CWM. At this point, the only thing I can do is turn on the device to see the "Samsung Galaxy S4" screen, attempt booting into recovery but never make it past the screen saying "Recovery Booting", or enter Download Mode but I cannot use it since I can't run ODIN on my work laptop .... stupid admin privileges!

Not sure what happened there.. very strange. But seems as if you have no recovery xD lol Maybe heimdall will work. Never used it not sure if it needs UAC to work. But dont use TWRP anymore
As far as your situation goes, maybe if you have the time and fast enough internet, see if you can download a linux distro (i recommend fedora as it is small and light) then make a bootable USB from that distro (if you have a flash drive) then use Heimdall in linux to flash the tar image.
Or just wait to get home. not sure how long your honeymoon is xD

I think I just need to accept that fact that I have been had and that the only thing I can do is wait until I'm home to use ODIN. Absolutely asinine in my opinion, however it seems the only logical conclusion at this point.
If anyone else cares to chime in with suggestions, please let me know!

I have had the same problem several times. The only way I have been able to boot up is to completely format data and either restore from backup or reflash a new ROM. If I wipe the dalvik cache after doing so however, it will not boot (hangs at the galaxy s4 screen like you said) and I will have to reflash or restore a 2nd time. (I'm using twrp too, but will switch to cwm if this happens again)
I m curious. Have you run into this problem again? Seems like every time my phone shuts off and tries to boot I have to restore from a backup that is days or weeks old. Super annoying. The first time this happened I restored to stock from Odin and did not use any backups in the hope that it would solve my problem and prevent it from happening again. No such luck.

I ended up having to wait until I got home to use ODIN. I ODIN'd up the stock .tar and then installed Philz touch recovery (CWM-based), then I did a full wipe of everything and installed a ROM. Problem solved.
With that noted, I abandoned TWRP and am now only using CWM on my wife's phone.

Same, TWRP just has too many problems.
CWM is much more reliable.

If you were using TWRP 2.6.0, that could have been the problem. I reverted back to 2.5.0.2 and like many others, have had no issues. If you had a TWRP backup, that might have fixed it early on.
I'm a newbie and I am in trouble. I have a rooted Nexus 7 2013 and I have a TWRP Nandroid backup which I had copied to my WIndows PC.
Now my Nexus 7 crashed and won't go beyond the X on bootup. The Nandroid and Titanium backups are on my windows PC.
How do I restore the Nexus 7 to working status by restoring from the Nandroid backup and data I have copied to the PC?
Please help. Thanks.
Guys, someone please help.
I don't know how to get out of this mess. I'm still stuck on X.
I can power off the Nexus 7 and power to the recovery screen where I find Teamwin's menu.
I restored (several times) the nandroid backups I found on this menu (they were all done after the last reset) but rebooting then just gets me back to the X screen and no further.
I have a good nandroid backup on my PC but no way to get it into the tablet so TWRP can restore from it. Is there a way to transfer a file to or from the tablet when it will not boot completely?
The advanced screen of the Teamwin recovery menu lets me access a file manager. Is there any way I can use it to move files on or off the tablet to "anything" else?
The last time the boot froze on the X screen, I was able to go to the recovery screen with the android on his back and an X and from there to a reset. But this time I cannot get there and the recovery screen gets me to the Teamwin recovery menu. This has a wipe option. Will this reset the Nexus if selected. Will it remove root? I don't want to go through rooting it all over again.
Essentially I just want to do 2 things:
a) extract data from the stuck Nexus 7
b) reset and restore the nandroid backup I have on my pc.
Please help.......

Just choose the wipe option in twrp.
That should allow you to start android.
Then copy your backup from PC to virtual sdcard, reboot to twrp, and restore.
You can copy files while in recovery but it is more involved so I would try this first.

But will it remove the root I worked so hard to get?
If you worked hard to get root on a Nexus device you did something wrong. It should be as simple as unlocking the bootloader (already done), flashing a custom recovery (already done), and flashing the SuperSU ZIP file (this is the only step you'd need to repeat).
That said, doing a factory reset should not remove root. Even if it does, it would be restored when you restored your rooted Nandroid.

Easy for an expert. I'm a newbie. I used the WUGfresh toolkit and it took multiple frustratng attempts and forever for it to finally download the correct adb drivers that would recognize the Nexus 7. Then all went smoothly.
But back to the present. I'm all fine now (till the next time the Nexus 7 crashes on me). For other newbies like me who run into this problem and need simple instructions here is what I did.
The first time this crash with the boot stuck on the X screen happened, going to the recovery screen (Power button + Volume up simultaneously) showed me the android on his back with a red triangle. Pressing power button and briefly volume up gave me the option to reset the tablet without removing root. Because I was traveling and did not have my TWRP backups with me (they were on my laptop 1,000 miles away) this removed all my data and I had to re-install all my apps and everything again.
The second time this happened, the recovery screen took me to the TWRP recovery screen. TWRP recovery had apparently survived the crash. I needed to save my data before reseting the tablet again. By trial and error I discovered that the TWRP menu has under the Advanced Tab a file manager. also discovered that if you connect a flash device to the tablet's usb port the TWRP file manager could read and write to it (!!!) in a folder called usb-otg (but not to my windows laptop). I copied what I wanted to save to the flash drive. Then I used the "wipe" tool to return the tablet to android.
I installed a free app, Recovery Manager, to reinstall TWRP recovery. Copied my previous TWRP nandroid backup to the tablet and restored everything as it was.
Easy as pie if you know how. I hope this helps some other befuddled user.
sfhub and raptir: Do you know what can be done to prevent this from happening again? Could Google Play being conected to in Europe after it was used to being to conected to in the US cause the problem? Both times the crashes happened shortly after I used the tablet in Europe and the the second time after I used it for the first time in the US.

I can't say for sure what is happening in your case, but in my experience getting stuck on X means your user data got corrupted. The cases I've seen fall into 2 categories:
1) faulty EMMC flash memory. Sometimes if you wipe a couple of times the bad blocks get locked out and you don't see the problem anymore. Other times, they keep coming back. In the latter case, return/exchange/rma the unit
2) android crashes (random reboot) and unfinished writes are not completed corrupting the user data. They put in code in the latest ROM to mitigate this so if you think you are suffering from this type of corruption, install the latest ROM if you haven't done so already.
Thank you for the excellent and clear reply. I'll hope the 2 wipes I did may have gotten rid of my bad blocks.
I'll update to the latest stock rom too.
Thank you.

The updating part got me in trouble.......
I accepted the system update and am now running android 4.3 but lost root.
So I went back to the WUGfresh Nexus Root kit. Updated everything, am now on version 1.7.3 of the toolkit, followed all the instructions (uninstalled and re-installed driveers) and got stuck on the same problem I had the first time I tried rooting: the adb : step3 of the full driver test. adb device not found .
I did reboot twice, am using the oem asus cable, etc. What a pain!!
Unfortunately I am dependant on the toolkit because I do not know enough to root manually.
Suggestions? Thanks.

So you're stock 4.3 now? Rooting manually isn't hard bud, setting up the toolkit is harder IMO.
You just need to download and install the Android SDK. Then download a custom recovery .img file, and a SuperSU flashable zip. Put the SuperSu flashable zip on your /sdcard. You'll then boot into the bootloader, open a command prompt and change directories to your Android SDK (Ex. mine is at C:\sdk\platform-tools) and run the command: fastboot flash <name of recovery file>.img
Then reboot into recovery, flash the SuperSU zip, reboot, done. You're rooted. There are plenty of How To's stickied in the General Forums for the N7 here.

Will look into your suggestions later because I am rooted again. It was the adb drivers again. The universal ones just would not work for me. The Samsung signed drivers on the other hand worked smoothly and then the toolkit ran smoothly and I am rooted. But it wiped out my TWRP recovery so I will re-install that next.
Thanks for the help.
About your advice, than you. But as a newbie I need clearer instructions. "download and install the Android SDK". Where? to the pc or the tablet? etc.
I need to learn more so I don't keep getting into these ridiculous binds!

Review the General forum for the N7 2013 here, as there are threads stickied to the top of that forum which has write-ups and video how to's that'll explain it all. I suggest to review those FIRST before you try doing things just so you can get a picture of what's going on. It may seem like a lot, but once you do it, it really is not.
The Android SDK is installed on your computer.
I got myself into trouble and I hope that someone who knows more than me can answer two questions.
Background:
I bought a new Nexus 7 2013 WIFI (razor / flo). I loaded TWRP recovery, and rooted the device. I decided to encrypt the drive, but TWRP doesn't appear able to do that (when the device reboots to start encryption, it just boots normally into Android). However it does appear that TWRP can mount an encrypted drive, so I decided to flash stock recovery to do the encryption and then reflash with TWRP.
Problem 1:
I accidentally flashed with the wrong stock image. I used the image for the Nexus 7 2013 Mobile (razorg / deb). The flash-all.sh script includes a step for flashing the radio (fastboot flash radio radio-deb-deb-g00_2.37.0_1024.img). It executed the command without error, but I don't think there is a radio partition on this device. Does anyone know if there is a radio partition to control the GPS, WIFI, and/or NFC? Should I do something to undo this problem? I cannot find a radio firmware for this device, and the WIFI and GPS appear to work fine so perhaps I should just move on.
Problem 2:
Even when I use the stock recovery image for the correct device, it does not appear to load correctly. fastboot runs without errors, but when I boot into recovery I get the unconscious android with the red exclamation in his tummy. I have done a full wipe of all partitions, and a full restore. Based on my search in the forums, this appears to be a common problem but the suggested solutions don't seem to apply to my device. Any suggestions?
I should note that re-installing TRWP works fine, and I was able to restore my data from a backup. But I can't encrypt the device or install future updates until I can roll back to the stock restore image.
Thank you in advance for your help.

Flash the wifi factory image. I assume you're talking about flashing in adb. Once you flash the correct image it should all be good. I've never even tried to encrypt the drive so can't offer any help there. If you use flash-all you will need to reflash TWRP afterwards then SuperSu.
Still no stock recovery

Thank you for trying to point me in the right direction, but I had already tried your suggestions.
The link you shared is for the official distribution of twrp. I tried it, and though it flashes fine, it did not help me return to the stock recovery.
I have been flashing the stock recovery from developers.google.com/android/nexus/images. It flashes without error, but when I try to boot to recovery I get the sick android (red exclamation mark). This happens whether I flash just the recovery image, or do a flashall, or an update.
I have been using fastboot instead of adb to flash the images.
Any ideas on why after flashing the stock recovery I cannot boot into it?

I'm sorry about the link, not that it does any good now but the link is corrected. Using fastboot to flash the images is correct, I too often use adb as a generic term for both. When you boot into the stock recovery you will see the android with the exclamation mark and that is normal. Finally got the new 2012 N7 I bought as a gift and was updating it. Been a while since I've booted into a stock recovery. So... Boot into stock recovery, when the Android with the red exclamation mark appears, hold down power first, followed quickly by volume up. You should now see the recovery menu. Whoop, Whoop! :laugh:
It works!
Thank you very much for your patient explanation. That helps a lot.
I hadn't realized that there was an additional step after the display of the warning android in order to enter stock recovery. All that time I spent trying to fix something that wasn't broken! <sigh>
I was unable to get the device to display the stock recovery menu, because it appears to require a very precise timing (I just keep rebooting it back to the system by accident). However, encryption did work fine. My confusion with the encryption was compounded by the fact that encryption of the Nexus 7 in 4.4 doesn't always work the first time (see this thread at android central: forums.androidcentral.com/google-nexus-7-tablet-2013/337078-experiencing-difficulty-encrypting-my-2013-n7-after-4-4-build-krt16s-upgrade.html). After trying 4 times in a row, the device encrypted. I was then able to put Team Win Recovery back on the device, and everything works perfectly.
Thank you again for your help. I don't see how to mark the thread as solved, but I am glad that everything appears to work now.
My device decided to randomly encrypt itself after using the CM12 port that is available. How this happened is beyond me. Anyhow, I tried to do a factory reset... Nothing would mount because the device was encrypted. So, I thought it would be a great idea to flash a different recovery. By now, I have flashed over 6 recovery images (all different) even the stock. Fastboot says that the transfer went through successfully only to find when I try to boot into recovery, it boots into fastboot instead.
Yes the device is unlocked.
I don't know if there is a ROM on it, but when i try to start it normally, it wont boot past the splash screen (before the boot animation)
Please help, as this is the only phone I am stuck with for a long time
Here's a thread with people that have a similar problem. There are some suggestions of what to do in there, but personally none of them worked for me. I ended up having to send it back to Amazon.

Never factory restore when you have a Custom ROM as it isn't made to reset with the devices stock hardware and causes things to go crazy.
Always use a nandroid of the original system with root, then unroot, then factory restore from that.
Also. YouTube search - HTC Desire 816 root unlock bootloader.
Use the .exe recovery from that video in fastboot at least twice without exiting fastboot or rebooting.
Now try the recovery.

Didn't work. Thanks though.

When you were on the stock recovery, could you wipe partitions?
Also what model do you have?
I was trying to degoogle my phone with adb pm uninstall following some tutorial, when I think I uninstalled something crucial under com.google.android.#### because the system crashed and went into a boot loop.
Is there anyway to recover the data I still have on my phone? Is it salvageable?

Are you able to get to recovery, or get to fastboot and then flash a recovery?
I'd make a full backup in recovery, restore same version of whatever ROM you were using, and then restore backup.

Hi thanks for the reply,
I'm in recovery mode now.
After downloading many different usb drivers (this one worked for me) and selecting the recovery mode option Apply update from ADB, I can now use adb devices.
The device is in sideload mode unfortunately and I can't use adb pull. Is there any other way to make a backup?
Are you able to get in to fastboot at all?
I was hoping you get TWRP or some kind of recovery working.
So thought I'd provide a quick update, after trying for ages to access any part of the filesystem, I was on the verge of giving up.
However by sheer luck, I found my phone was not too corrupted to launch safe mode, as a result I was then able to transfer all my files before resetting the phone.
Keep this on the dl before they get rid of adb to. I'm glad you fixed it, but is it deGoogled? Using adb I'm pretty sure a factory reset would fix just about anything. I had no Gapps for about 3 hours once, I found it very annoying, lol. Googles claws are sunk way to deep for me to live without.
