its not a real error, mmcblk0p2 is optional, its a second partition with linux format on the SDCard

Try wipe cache and data after the install. It not Flash T-Mobile 2.2.1 stock
I had the same problem, and it was solved by
flashing T-mobile 2.2.1 stock (link found in xda).
However a later thought (without proof) is that
you should wipe both cache and data AFTER the
installation of the new ROM and this might help.
Please update.

This message is harmless so you can easily ignore it.

harmless it is haha.
anyway my prblem is I still cannot do any nandroid restore or backups.
why?cwm gives my **** of errors.
I think its sd-ext or something like that

Used ODIN to go back to stock and now stuck on SAMSUNG screen

I can get to download but nowhere else
the phone wont get past the glowing Samsung after the ATT "rethink" animation
I used ODIN 3.07 and the root69 LG1 file

LG1 from here?
http://forum.xda-developers.com/showthread.php?p=31039805
Try using ODIN 3.0.4

SIMPLE FIX....
preform factory reset in recovery before (or after) flashing stock.
Stock odin flash does not flash or wipe data partition. and some files that you have in there become incompatible with older firmware and stop stock from booting.
NOTE!!!!! factory reset from STOCK recovery WILL WIPE SD CARD TOO!!! CWM recovery factory reset WILL NOT wipe sd card... backup your pics and downloads!!!!

I had a similar issue and was able to resolve it by using this guide to install CWM
http://www.androidauthority.com/galaxy-s3-sgh-i747-att-clockworkmod-recovery-99791/

reviving this thread because I'm having a similar issue. It was all my own doing I know I know. I was flashing the rooted/cwm tar from the sgs3 toolkit and the phone would do this thing where it would show the first 2 boot screens then go black and keep the blue LED on which actually alternated from lightblue to dark blue. I then tried to flash stock which did nothing. Then I got it to boot past the boot screens and show me both the samsung and att animation. it now hangs on the SAMSUNG screen. when I try and wipe data in CWM (6.0.2.3) it says this
(re-written)
-- 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.
I cannot get anything to wipe or mount and I cannot efs clear it in odin. I would love to be able to get back to stock since I believe this is recoverable. Thanks for reading my mess of problems and attempting to give some advice.

If you Odin back to stock, it should give you the stock Recovery, not CWM or TWRP. Try doing the Odin to stock again, then use the stock Recovery to reset to factory defaults.
If you used a JB stock with Odin, then try using an ICS stock with Odin. ICS is more reliable when it comes to fixing flash issues.

it looks like you didn't wipe cache and dalvik.
just go back to recovery and wipe them.

Don't know what I did but I fixed it. Thanks for replies. We can lay this thread back in the ground now.

Also, CWM gives me error message on load:
e: cant mount /cache/recovery/command
e: cant mount /cache/recovery/log
e: cant open /cache/recovery/log
e: cant mount /cache/recovery/last_log
e: cant open /cache/recovery/last_log
Additionally, phone switches off itself when idle in CWM ;/

I did all wipes except dalvik cache, because when I open that option the recovery goes back to the initial menu again.
and what about the backup thing?

you need to revert filesystem back to rfs(i am working for a convert tool but need some time,so you'd better follow the guide)
http://forum.xda-developers.com/showthread.php?t=1915998

Are you on the latest 6.0.2.9? The 5.*.*.*. Doesn't work well with the newer roms. Update your cwm or switch to twrp, then you should fine.

No. It's been so long I forget what all happened but during my attempt to fix it, I hard brick it. It was dead as can be, no life. Sold it as is. However, I bricked it because I made the mistake, the fix is out there I believe it is a matter of repartitioning the internal storage using ADB which I have limited knowledge of.
Good luck!
