Need help with 'Nand Kernel Open Failed' while running backup in recovery.

I've done a bit of searching for my answer, however, am not able to find the answer.
I am having a problem running a restore in AD Recovery in the Magldr (v1.13).
Let me explain the situation:
I wasn't able to get App2SDPro to carry over apps to my SD card. I was informed it was because it was that I did not have an EXT2 or EXT3 partition on my SD.
I did that and then my SD was erased, but luckily I make regular backups of my SD card.
So I put all the information back on my SD card. I then realized that my ROM was erased as well.
So I tried running the backup I made from the recovery and got the error mentioned in the title.
I then tried to reload a ROM that I have on my SD at all times and then tried to do an advanced restore of the data and system and cache while leaving the boot but nothing works..
Am I destined to start from scratch, lol? (I had 140 apps installed)(and I'll be using a different form of backup next time, lol)

i have the same problem . while i was recovering from nand backup i have this notification 'Nand Kernel Open Failed'

Just flash again the kernel of your rom or the rom without wipe

you have to flash your rom om the kernel again and hopefully the problem will be solved

[Q] Unable to mount data after restoring partition

Guys, need help. I used this way way back (genokolar partition) http://forum.xda-developers.com/showthread.php?t=1112857 Im planning to go for ICS yesterday, i flash back the official partition, now my phone stuck at IDEOS logo. I tried wiping everything and reflash (tried MIUI,CM7,Elite SX still no luck). I use Miui before flashing the official partition. Im pretty sure i did what the step asked. Flash, no clear/wipe. Stuck at Ideos screen. Then i clear and wipe still the same. Then i go to the pink screen, restore back the original recovery and BOOT files, and flash back the official froyo, error at 2/2 update. I cant mount data in cmw. Tried factory reset in recovery but no luck, got error msg ( Mount data error ) using 4.0.0.5. I cant delete/wipe data.Keep giving me error mount data. Even in official recovery cant mount, got msg ( no such directories,Can't Mount @(or/dev/block/mmcblk0p13 ). Is this the problem ? How can i mount the data back?

Did you try official gb? You don't need froyo, it has wrong kernel for ics aurora.

Can't mount sd? Go to recovery, take your sd out, and put it back in. If that works, you try flahing the custom partition again (not the original partition). After that, try flashing a rom.
Edit: but try to flash the original again first. Make sure you flash it, reboot recovery, flash it again, reboot recovery, and then flash your rom.

hmm i would probably try restoring sans odin...should fix whatever partition issues your having

I had to restore from KIES...
Wouldnt boot again.
Go in stock recovery and
Format data / factory RESET the thing...
WTH I almost tought i lost it for a sec !!

Never format data. What you should have done is odin back to stock, then factory reset through stock recovery. Kies is hit or miss when it comes to recognizing the phone in that state. You got lucky. There are a few topics on how to fix the problem you had.

I format /data every time I flash a new ROM and I experience fewer bugs because of it.
I just back up all my important files (data folder) to external SD and then restore after I install the new ROM. Works great for me. :good:

What do you use to format data ?
Stock ?
CMW ?
TWRP ?
Thanks

I'm mostly on TWRP but I do it in CWM also.
At most, your issue (whatever it was) was due to user-error or a random system glitch.
At worst, you have to ODIN back to stock which only takes about ten minutes to do, five minutes to re-root and install TWRP and then you're good to go again.

Don't know if any further research has been done on this subject, but it's the only thread that came back with TWRP+format.
This same thing happened to me last week, I *think* it was my first internal format on my i337, was able to boot then fail.
Odin back to stock fixed issues.
Any thought why this happens? Any suggestions for best clean format approach besides an Odin? Flash CWM/Philz for the format then back to TWRP if desired?

I'm currently stuck in the same situation. Used TWRP to format /data to try and clean up the internal sdcard and now I'm bricked. Flashed 3 diff recoveries and about a billion roms, nothing works. Downloading a fresh odin flashable stock rom as we speak.
edit: so flashing stock rom via ODIN wasnt quite enough. I then had to enter stock recovery and do a factory reset. I noticed any time I tried to format /data the system would crash and reboot. The stock recovery was able to properly format data and now I'm back on a custom recovery/rom again.

[Q] [Solved] Data not being formatted!

Hi,
I have installed Ultra Gb revolutionary 1.6 Rom and have been using it for a while. I wanted to remove all content on phone..so i tried to wipe data and reinstall the rom again. Rom flashed correctly and i rebooted the phone..but user apps were not removed, they are still on the phone.
I tried changing kernel, flash another rom, flashed utra gb again, the apps are still there, why?

You can try to conenct your sdcard to your PC and delete .android_secure, it contains sd apps that don't get deleted with /data
If it doesn't work you can use Wipe data option in settings :good:

Well, that may be a kernel issue! Try to install stock kernel/ROM via odin and get it all clean!

I think that's not the kernel, he said he tried to change it, i think he haves a problem because /data is not mounted,
OP use CWM and mount /data, then do wipe data & cache

While selecting Factory reset on cwm, data & cache are automatically mounted and both data, cache and .andtoid_secure is wiped! I'm jst sharing my experience, it happened with me few times while using percy_g2 kernel! The best option for me was odin!

In CWM in general partition is mounted when wiped, I think switching kernel and try again
Flash another CM kernel and wipe data then return to your kernel, or do a factory reset from setting in phone

Try to use odin. Your userdata.img may be Corrupted
Press Thanks if Helped

Well a simple solution to the problem :
1.Go to CWM,mount all the partitions and flash percy's kernel (CyanogenMod #2)
2.Go back and then go to advanced > reboot recovery
3.Now you'll be in Percy's recovery and from there,under mounts and storage,format data and format cache.
4.Go back and then go to mounts and storage and mount all the partitions.
5.Flash back to bieltv.3's kernel and reboot.

Finally, i had to flash flash stock Rom via Odin and go back to ultra gb.. Thanks for all the help guys

First things first, try booting regardless, every time I flash the stock Oreo rom V20A, it says no os installed
(I recommend having an SD card to put the rom on) go to wipe and format your data, once having done that wipe everything Dalvik, Data, System, Cache. But not the SD card. Then after that, go to flash, select your SD card then flash the rom.
