I have n7100, I had corrupted EFS partition, because of which my phone was stuck at samsung logo. I had no backup of EFS partition, so I flashed the EFS i got it from online. My phone was able to boot without any problem but Cell phone is not getting registered to provider because of IMEI.
Next I wanted to root the phone.
I flashed the root file (CF-Auto-Root-t03g-t03gxx-gtn7100) from odin and in haste immediately flashed the recovery file without waiting for the next reboot.
Usually the root file installs the stuff after the first reboot, in my case it didnt happen since I installed recovery on top of that.
Now I am facing problem in full flash with pit file. Odin is stuck in Set Partition, Get Partition Mapping.
I can access Download mode and recovery.
In recovery the following errors are shown
Cant mount /system
cant mount /efs
Is there anything I can do to make the full flash work?
Your eMMC chip is corrupted, or, worse and probably, you have SDS.
Try and flash a stock ROM
Change the USB cable

There are a number of threads throughout xda-developers, but I had a very long journey to find a fix that worked with my T-Mobile T989 Galaxy S2 phone. In a nutshell, sometime over the last week I somehow corrupted my /efs directory/folder enough so that it wouldn't mount. The symptoms I started to have was that I couldn't load any custom ROM without it going into a boot loop eventually. Even the backups that I saved would not work! I was able to use Odin to factory reset my phone back to 2.3.6 gingerbread, and it would run, but if I tried to load any ROM including going thru a Kies factory update, it would fail. (Note I still had a valid IMEI number displayed) Then I saw the failed to mount /efs error on the factory recovery window. So after many attempts to find and try a specific fix for my T989, I came across this thread in the Skyrocket phone section. This guy named icenight89 came up with a method to fix their phones, with a note that it will work on T989's as well.
The fix for me that worked was for me to factory reset to 2.3.6 via Odin. Then load in CWM recovery and then Super-SU to root the phone. Then download a file on icenight89's thread called EFSFix.zip and upload it to your phone. (Nandroid backup first) then boot into CWM recovery and install this .zip file, and reboot, and voila the efs partition is mountable again!! Here is the link to icenight89's thread and in there are the file links: http://forum.xda-developers.com/showthread.php?t=1611796
Hope this can help shortcut the fix for our phones for someone else who runs into this.
I just got a note 2 (i317m - canadian carrier model) that got messed up some how. When attempted to boot the phone it said unable to mount efs partition. My research tells me that partition that contains module info such as IMEI, bluetooth, wifi are stored in that partition. Now I realize why the repair guy wanted $350 to fix it.
Is there a way I can tackle this problem on my own and try and fix it? Apparently there is a tool here in XDA that can wipe the partition but I am not sure if that would rebuild it and allow me to mount it so I can create a new data file with the IMEI number in it.
Where should I start to attempt to fix the problem.
Please note, I can still access recovery (currently TWRP installed) and download mode and use ODIN if necessary to flash back a stock rom BUT can't mount to the computer for any file transfers nor can I boot the android device (stays at samsung logo). I have no issue using ADB is neccessary if I am lead in the right direction. This phone is already trashed in the eyes of the owner so its basically a little project for me to tackle when i have time to kill.

Have you tried flashing your official rom? Flash your official firmware by downloading it from sampro.pl or sammobile.com, flash it with PC Odin under PDA tab.
After you done, don't let reboot your phone, goto recovery by pressing vol up+ menu key then power key(continuously hold it until your phone restarts might be 4~8 secs.) Then check 'Wipe Cache Partition', and then reboot phone.
Yup and nothing worked.
Anyone?
So the only solution is a $300 fix?
Today my N7100 suddenly rebooted without any warning and got stuck at initial Samsung boot logo (even sound gets into loop). I managed to enter recovery and tried to wipe cache partition. But every time I try to wipe anything or delete via twrp file manager - phone reboots
Should I try re-partitioning via Odin? What pit file do I use?

you can try to use Odin, but probably you have faulty eMMC, many similiar cases around the forums about rebooting and stuck on Samsung logo.
Probably PC won't recognise your phone and there will be nothing else to do, but to give it to service
Miracles happens! Re-partitioned and fully erased nand via Odin and managed to upload the rom! Have tried 3 time before it succeed (crashed few time on system and cache image writing). Everything seems fine so far. Won't upgrade the rom from the stock 4.1.2 for a while to keep phone working. I have the insane emmc chip by the way. Hope it won't fail again.
Hi I was wondering if someone could help me.
My dad's phone which is a S3 somehow soft bricked itself. It was on a stock rom before.
It turns on and then gets stuck on the Samsung Galaxy SIII screen.
I am able to boot into download mode as well as recovery.
I was able to flash a stock ODIN file UVUEMJC as well as the PIT file and everything went smoothly and it passed.
However, the same problem remains, it is still stuck on the Samsung Galaxy SIII screen when I boot it.
Also went into recovery and tried to wipe data, but it is unable to mount any partitions, e.g. can't mount cache, can't mount data, etc.
I was able to throw on TWRP and boot into that, and it gives me similar errors as the stock recovery. TWRP also says that my internal storage is 0 GB and I can't put any files onto the phone.
I am quite confused because if NAND was corrupted then I shouldn't I not be able to boot into recovery at all?
ADB is also working...can't push/pull anything though.
If someone could help me I would really appreciate it. Thanks.
So I flashed CWM cause I read on XDA someone said that formatting data through CWM works, now...it says there is no pit partition and there is a flash read failure whenever I try to flash a stock tar with odin w/ pit. Also tried flashing pit by itself, doesn't work.
Try installing cwm or twrp again, boot into recovery, mount sdcard0, connect to Windows machine, and try to format the partition using fat32.
So, a little background. Full stock recovery, latest Telus 4.4.2 firmware.
Phone may have suffered a drop and/or some water damage during an episode of blackout drunkenness. Yes, I know, I'm an idiot.
Worked fine for a day or two, then began randomly shutting off, seemingly at times when the phone's CPU was under stress. Keeping it in airplane mode seemed to help avoid the reboots somewhat but not completely.
This began right before I was leaving for vacation, and had no time to go replace it. Then, after successfully taking a bunch of awesome pictures while on vacation, the phone decides to go into a boot loop. Can only boot into download mode.
I've got another phone now, but would REALLY like to get the data off the phone if at all possible. I'm assuming there must be some hardware issue at this point causing the boot loop, so I'm guessing that restoring the phone to 100% original working order is probably out of the question.
Any suggestions? I'm guessing something got corrupted, but I'm wondering if maybe I can flash a new recovery or re flash the stock rom via odin and hope it boots up long enough to get the data off? Will it wipe all my data if i try to flash via Odin? Should I take it in for a JTAG? are there other options like getting someone to dump the data off the memory chip somehow?
Thanks in advance.
Since the phone will enter download mode, I suggest flashing twrp 2.87 onto the phone, boot into recovery, mount the data partition, connect the phone to a computer, and try to copy the data to the computer.
Okay, where is a reputable source to download Odin, and what version should I use?
Also, can you provide a link to the exact instructions for flashing TWRP? I looked at the info available on their website and it's not that clear...
And so once I've booted into recovery and mounted the data partition, I leave the phone on, correct? Dont do anything, just connect it to the PC, and it should show up there?
Thanks so much for your help

Okay, I was able to flash TWRP successfully and boot into it.
However, when I attempt to mount the data partition, it won't let me. When I go into the log files, it says unable to mount /data, unable to mount /system, unable to mount /cache, etc......
Also says Internal Storage 0mb ....
So.... i'm guessing this is really not good
Any further suggestions??
If it can't mount the partition and the size is 0, looks like the internal memory is shot.
The only other thing you could try would be to re-flash the stock ROM without wiping anything to see if it will boot. If it fails to flash via Odin, I don't there is much you can do.
