Hi,
I've been trying to install a custom ROM on my grand duos to replace the china unicom rom that restricts access to a lot of things and have run into problems. I have managed to install a cwm recovery using odin but formatted all partitions in the process and now I can't mount the /data partition. The phone is stuck in bootloop when I try turning it on, I have tried using a .pit file to repartition but no success. Can anyone help?

I've already looked through previous posts and there seems to be no avail.
From 4.1.2. stock build, UVDMD5, (I'm assuming, that's when I bought it)
I tried to flash 4.4 ROMS onto it, Both Gummy and Beanstalk with their respective Gapps.
It wouldn't work and I wiped and reset and odin'd in the original firmware UVDMD5, so it successfully led to the beginning phone setup ONCE.
Then, from stock, I figured why not root and flash the ROMS once more? and this time, the galaxy would not have it.
I odin'd myself after the roms failed once more, but now..
Now the phone is stuck at the SAMSUNG loading boot screen.
Everytime I odin in the UVDMD5 setup, it says it's successful but constantly stuck at the boot screen.
I can get myself into recovery but no options are available to me.
If I try to progress forward, the roms will not work and I realized what might've done me in.
Once the roms in the very first trials wouldn't work, I messed with the mounting to see if it would change anything(HUGE mistake I now realize)
I think I unmounted /data and /system and pretty much everything!!!
I'm in the stock recovery so I could pull .zips from the external SD and I've tried to put in Cyanogenmod Recovery so I could get to the mounting options,
but now everytime it says that signature verification failed.
Tl;dr: I'm an idiot and unmounted everything and now it's stuck at boot screen and odin doesn't work. PLS HELP!
ps: ignore the ageold signature
First flash the very latest Recovery with ODIN. You will need to put the phone in download mode to do that. Next, flash Root66 version of UVDMD5 via odin and then flash Rom of your choice via Recovery.
I've taken the root66 and finished odin'ing it in, but no success. It's still stuck on the SAMSUNG screen.
When I boot up to (stock) recovery, the first red messages that appear is
E:failed to mount /data
can't mount '/data' (invalid argument)
and when I go into >apply update from external storage and try to apply cyanogen latest recovery,
all it gives me is E:failed to verify whole-file storage.
There is no /data, what do I do?
Please flash CWM Recovery via Odin.
First of all, thanks for sticking with me for this long.
I successfully installed Clockwork with odin and I thought this would be the end, but
It successfully mounted /system and /external_sd but,
Error mounting /data!
Error mounting /sdcard!
I don't know what to do from here. Is there a simple fix?
Did you flash latest version of CWM ? If yes then try Factory Reset in the Recovery.
I did factory reset it:
. . wiping data . .
formatting /data . . .
Error mounting /data!
Skipping format . . .
Formatting /cache
Formatting /sd-ext
Formatting /sdcard/ .android_secure
Error mounting /sdcard/ .android_secure!
Skipping format . . .
Data Wipe Complete.
Is what shows up and still /data and /sdcard cannot be mounted. Anything else? I'm desperate.
Part 2: I tried moving past all that and tried to run the ROMS, but it goes on to tell me:
This package is for "d2tmo" devices; this is a "d2vzw"
what does that mean?
Can you manually mount SD Card in the Recovery ?
I'd not try any roms until this issue is resolved.
What do you mean by manually?
The external sd card can be mounted, I'm pretty sure it means that the internal sd can't be mounted.
How would I mount internal in recovery? the options says it can't mount /data and /sdcard
Try TWRP Recovery.
Hi all,
Let me start with the fact that I did something really stupid, I formated the storage in TWRP (version 2.8.0), instead of just wiping the dalvik, data and other. After that I installed the custom ROM, however the tablet would not boot, it stays at the boot animation. If I go to the TWRP, I see that the internatl storage is 0MB and it says it cannot mount \data and other files.
I tried installed other ROM as well but same thing.
Tablet is rooted.
Help me please to recover the tablet (P600)!!

Load the rom on an external sdcard, and flash from there. I usually wipe everything when flashing a new rom except for the external sd card. If that doesn't work, try booting into the odin download mode and reflash to stock firmware via ODIN. Then try flashing again.
My Note2 had seen file system related issues (sd card directories renamed to u..., etc.) and finally it stalled at the Samsung logo one night. Booted into recovery and seeing "failed to mount /efs", also /system, /cache, and /data.
Any suggestions? I tried Kies but no luck, I guess the Samsung tech in Bestbuy probably did the same thing. I've been reading through this forum and found this file Stock_Partitions_N7105_T889.zip. Could I just use this without reflash the OS? If so, how? Hopefully I could get back some of the files on the phone. I haven't tried Odin or twrp, or root the phone yet.
Thanks in advance.
Flash TWRP using Odin. Boot into TWRP and see if you can pull off your data. If TWRP mounts the data partiton and you cannot find any files, you may be out of luck.
If you decide to live without the phone's data, you could try to revive the phone by flashing a stock ROM from sammobile.com using Odin.
Hello, I was on a meeting and I turn off Note 2. After this it was stuck on boot logo. My TWRP is v 2.8.0.1 It says there is no os; Internal storage is 0mb, External storage is 0mb. I tried sd card on other phones. It worked. My PC can't recognize my phone. Also:
- unable to mount ''/system; data; cash; efs; internal and external; no valid storage partition found for MTP etc.
Is there anything I can do about it? Thanks in advance!

Change the file system to ext4 (for every partition possible). I had the same issue. You will loose all your data in internal storage. And you probably have to flash new rom.
You could try flashing a stock ROM with Odin but you will lose your data.
Ok... thanks... I change he file system to ext4 (for every partition possible). In recovery i wipe everything - loosing data is not important. Now I have problem with Odin. I tried to flash stock 4.4.2 but i have sbootbin fail. My latest ROM (i think) was 4.4.4. What can I do?
Did you confirm the model # in download mode? Sboot.bin is not flashing in Odin because the ROM is not made for the phone.
Did you try using different USB cables and USB ports? Tried using Odin 3.07?
The ROM is official, and latest for my country and carrier. I dont know if there is a problem with custom rom that was on my phone before - which is 4.4.4. I tried with Odin 3.12.3. Now i downloaded Odin 3.07. and now it says NAND write start! FAIL!

Try flashing any custom rom. When i faced this issue, i just changed every partition to ext4 and then flashed a custom rom of my choice. And everything went normal.
How can I flash custom rom when I cant see my internal and external storage (it says = 0mb and all folders are empty). I tried different Roms with different ODIN's- mostly Nand write fail! I cant change internal storage to ext4 because :"Invalid partition selection"! Can I flash custom rom with Odin?

The 0mb issue isnt fixed by changing file system??
Remove any sd card if you have inserted. Try again to change them.
In my case i fixed 0mb issue by changing file system to ext4. Nothing else.
No... I have 0mb.. I changed available file systems to ext4 with and without sd card.. Is there any way to do something?
Your only hope may be flashing the phone with a jtag cable. If that doesn't fix the problem, the memory is defective.

Do you mean that you cannot mount the data partition in TWRP?
