[Q] N5100 in critical state?

Hey guys,
Yesterday I noticed my My Note 8.0 looping on it's bootscreen. The screen was also flickering...
I haven't been able to reboot the device ever since... I have tried al the conventional ways...
First attempt was through stock recovery... it returned a fail error message when I tried to factory reset, wiping cache,... every option available gave some kind of error:
Code:
E: failed to mount /system (Invalid Argument)
can't mount /system (Invalid Argument)
E: failed to mount /data (Invalid Argument)
can't mount /data (Invalid Argument)
Device has always been rooted. I have done this soo many times so I am 100 % positively sure that I didn't do anything that would explicitly cause this kind of error. So I am sure that I didn't remove or alter any files in system or data directory.
But anyways... How can I fix this...
Device doesn't get recognized anymore by my computers...

You are rooted but no custom recovery? I take it you do not have nandroid to restore from? I have only had this tablet for a few days but imagine it being Samsung you can Odin back to factory stock if you don't have a backup or flash a stock image from stock recovery: http://forum.xda-developers.com/showthread.php?t=2289441

I did have CWM Touch Recovery installed prior to the showing up of this error...
Device doesn't get recognized any more by any computer I own (different OSes, no success on neither one of them...)

I was trying to address your issue with it not booting properly. Have you gotten it to boot up? Did you have a backup to restore from in CWM?
As for recognizing on the PC, I'm sure you probably have the correct drivers installed already. I have had the same issue on my S4 and have not found a solution yet so have been using a cloud service or yanking the card out to transfer. Have not tried it with the Note yet.
**Edit....I might add that most will suggest checking the USB cable and trying different USB ports (to get on a different IRQ) but none of this has worked for me in the past. Might be worth trying at least to make sure.

I'm gonna bring it back to the shop and hopefully, if I put up a poker face if they ask me about rooting my device :angel:, they accept it and treat it with warranty

For some reason, I really don't know what I have being trying...my tablet miraculously is working again!

[Q] Factory Settings - pre operating-system

Back story: OTA update to 4.3 killed USB on this phone, so there is no USB access to it - at all. I don't have a Windows computer, so I never downloaded ODIN to root the phone. It is completely stock, other than the unlock code obtained from T-Mobile.
I just switched from T-Mobile to AT&T, and for some reason had no data connection on the phone, even with the correct APN settings. I decided to try a factory reset. I went through the system settings menu and found the "Reset to factory settings" menu item, selected it, acknowledged the warning, input my PIN and let it go to work.
A few minutes later, it had rebooted into recovery. Sicne it was there, I took the opportunity to use the boot-loader's reset function and wiped the cache while I was at it. That was a mistake.
Now, the phone won't boot past the pulsing Samsung logo. I can get back to the recovery, and it pops up these errors - first, the droid on his back with the red triangle over him flashes "No command", and then it dumps me to the recovery menu with this scrolled at the bottom of the screen:
Code:
# MANUAL MODE #
-- Appling Multi-CSC...
Applied the CSC-code : TMB
Successfully applied multi-CSC
E:failed to mount /data (Invalid argument)
can't mount '/data' (Invalid argument)
E:failed to mount /data (Invalid argument)
E:Can't mount /data/log/recovery_log.txt
It's obviously soft bricked. I can't use ODIN to flash anything. But, since I'm at the recovery screen, it is giving me the option of loading an update from external storage - what should I put on the SD card to load in order to fix it? Can I fix it without ODIN?
edit to add:
I've already tried the stock UVUEMJC firmware from DocHoliday77's thread, but it threw a bunch of errors across the screen that I didn't catch in time and rebooted to the same point.

Try @saranhai's StockMod Rom. Put it on the External SD and flash it. If that fails, please post the error log.
On another note. can you try in Recovery and manually mount /Data Partition ?

Stuck @ work today, and I didn't bring it with me. I'll give that a shot when I get home tonight. I don't recall seeing a "mount" option in recovery - it's the stock Samsung recovery, I'm not sure I made that clear in the OP.
My Nexus 5 arrived last night, so this is becoming a project for me. I just want to know if I can make it work, but without USB access to it, that is probably a non-starter.

If you have Stock Rom, there isn't anything you could flash that way. At the most you could flash a Stock firmware via KIES.

[Q] Serious help needed! failed to mount /data

Ok here is the story about a year ago I rooted my AT&T GS3 installing CWM and Cyanogenmod. I hadn't had an issue until mid-september. For some reason one of the updates caused certain phone functions to quit working, specifically my mobile data. I searched around on the internet and found out that it had probably affected my modem files, and was told to flash back to stock and that that should solve it. I found a stock firmware file and flashed it with odin. When my phone rebooted it boots to the point of the samsung emblem with the oscillating blue background and just sits there. I tried flashing different versions of the firmware to the same result. I later learned I probably flashed just the modem which I found while trying to solve the problem. When I boot into stock recovery i receive the following message:
E:failed to mount/data (Invalid argument)
can't mount '/data' (Invalid argument)
# MANUAL MODE #
-- Appling Multi-CSC...
Applied the CSC-code : ATT

Anything will help because I am currently without a phone so.... thanks
Edit 1: The Firmware I attempted to flash came from samsung-updates.com though I am not sure of what build and can't check since it won't boot all the way

What firmware build are you on?

I cannot tell what build, I got it from samsung-updates.com in a zip titled ATT-I747UCDLK3-201211116120549

I would download it again in case it was somehow corrupted. The build is in the filename, LK3, which appears to be 4.1.1. I would say to try 4.1.2 instead, but it appears that wasn't released by AT&T either.
Or if you want you can try flashing the root66 firmware instead. It's LK3 too, only pre-rooted. It's in this thread: http://forum.xda-developers.com/showthread.php?t=1739426
Either way, redownload and try flashing again. Then boot recovery and factory reset. (Will wipe internal sd)
If it still won't mount /data, try flashing Twrp recovery and factory reset. (Will not wipe internal sd unless you choose advanced > Format /data.)

Thank you so much! I ended up having to flash twrp but when I did what you said it booted just fine. Now the only question remaining is do I try to go back to cyanogenmod?

Since you have TWRP working, copy CM11 to your phone, boot to twrp, and flash CM11. If CM11 does't boot, try wiping data, cache, and dalvik.

Just remember, anytime you go between different based roms, such as TW and CM, you have to factory reset or it'll hang during boot.

[Q] Stuck On Boot Screen Even After Flash With Odin

I drop my phone one day and this nightmare started. When I power on my phone it then stuck on bootloop. I then start the phone in recovery mode and I got the error messages as below.
Code:
# MANUAL MODE #
-- Appling Multi-CSC...
E:failed to mount /system (No such file or directory)
can't mount '/system' (No such file or directory)
E:failed to mount /data (No such file or directory)
can't mount '/data' (No such file or directory)
E:failed to mount /data (No such file or directory)
E:failed to mount /system (No such file or directory)
E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/log
E:Can't open /cache/recovery/log
E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/last_log

E:failed to mount /cache (No such file or directory)
E:Can't mount /cache/recovery/last_install
E:Can't open /cache/recovery/last_install
E:failed to mount /cache (No such file or directory)
Then I go on and try to flash with stock ROM using Odin. I am pretty sure I did the steps right as I follow online instruction and I flash my phone before. At the end my phone just stuck at bootup screen and when I try in recovery mode it shows the same error message as above.
Is anyone have any idea how to get this fix? I am suspected that my internal storage is corrupted but that's just my guess. Thanks in advanced!
*****I notice that when I start Odin it get through the "Get PIT for Mapping" step very quickly unlike what I saw on any other youtube video. Is it possible that my phone PIT is corrupted and need a new PIT file?

try downloading this and flashing via odin
http://forum.xda-developers.com/showthread.php?t=1975560
i just had a problem with trying to restore a stock rom using twrp and got stuck in a boot loop, even after wiping and installing another stock rom... then i flashed this one via odin and for some reason it worked and i'm back into my stock rom w/ root.

I did try flashing with Odin but it end up in a bootloop. I will look into the thread you provided and see if I miss something. At the meantime, I hope there will be another way to work around.

I search online and found someone having the similar issue to their phone but it is on HTC device.
http://forum.cyanogenmod.org/topic/6433-solved-messed-up-partitions-on-internal-storage/
Therefore, I believe my internal storage partition is mess up or corrupted and need to repartition. In order to do that I believe I need the PIT file for my T-Mobile Note 2 is that right? If so can anyone provide me the PIT file for T-Mobile note 2? Or is there something I am missing still?

Anyone have any idea about this? Please I really need help on this.

Really sorry I missed your previous post. Have you tried to ODIN a custom recovery? Download this and flash with ODIN, then try to boot to recovery.

If you can get to recovery, follow the instructions in my ROM thread for wiping. If you want to give my ROM a try, download the D edition. The wifi will work no matter what bootloader you currently have installed. You'll have to take out your sd card and get the ROM file on there with another device before you proceed.
http://forum.xda-developers.com/showthread.php?t=2631278
This is a T-mobile stock, rooted and debloated ROM. There is a link in the thread for the stock 4.3 modem to flash too in case you need that. Put that on your sd card too.

I tried flash the CWM recovery with ODIN but my phone start bootlooping and cannot get into original recovery again. I believe my phone's motherboards is damage in some way that cause the internal storage fail to be detected. Do you think putting in a new motherboard will work? I search on ebay and it's like $80 for a new working motherboard.

If you haven't figured this out yet I'll throw in my 2 cents.
Start here: http://forum.xda-developers.com/showthread.php?t=2678420
I don't know exactly what heimdall is but odin should work just fine for this. Try a few different odin versions if you have to as it has changed a lot over the years since the release of this phone.
Also make sure to uncheck reboot from odin, unplug after reflash, pull battery, then manually go to recovery immediately after flashing. If you get anywhere besides the TWRP you have to flash again.
