Need help with 'Nand Kernel Open Failed' while running backup in recovery. - HD2 Android Q&A, Help & Troubleshooting and Genera

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

[Resolved] Boot Loop due to corrupted filesystem CWM 2.5

So just wanted to share this in the event anyone else runs into the problem. I was running CWM 2.5 and CM7 RC2 just fine for a while now and I decided to clean my SD card yesterday since I have tons of empty folders from prior app/rom installs. After deleting some folders, my SD card would not be read by the phone. I rebooted and it sent it into a bootloop. Tried to format SD card in recovery and the settings menu, no avail. Tried to partition in adb to correct the issue and /DATA would not mount for the life of me. I could get it to mount via adb, but not in recovery. Any time I tried to factory reset or format DATA, it would say it cant mount the partition.
Anyway, I tried the latest version of CWM (3.8) and it managed to format each partition without any issues. I could then install CM7 without any issues and it booted right up.
So if anyone is experiencing SD card issues when altering the filesystem in any way, try upgrading the recovery image. It would have saved me a good number of hours troubleshooting, but hey at least I learned adb better lol
I am having the same exact problem, bootloop with no way to access card. How did you get CWM updated?

*solved* /data/data/com.google.videos/cache/-1755362040.cacheError while fo

ok im freaking out a little, hopping that you fine ppl here at xda can help me agian.
i had a working rom on my tab, md's alaxandra III witch was my first rom it was great but i decided to check out another with a lil more customization. i did a backup and flashed the new rom.
it was a little twichey didnt run smooth so i decided to revert back to md's rom.
the first backup had an eror, i cant remember exactly what it said something about android media, so i tried an older one.... same thing. it was able to boot after the restore, i could see my custom live wallpaper so the restore somewhat worked but there was a force close window up that would not go away.
so i decided to just whipe and flash original zip for md's ROM. that did not work now im stuck in a bootloop.
HELP ME PLEASE!!!
how can i fix this my wife will kill me if i brick this lol
this isnt looking good... usually i get a fast response
when trying to restore i get
error removing /data/data/com.google.videos/cache/-1755362040.cacheError while formatting/ data
then when it boots i get the application launcher (process com.android.launcher) has stopped unexpectedly. please try again.
this will not leave the screen
Can you get into recovery? Try wiping everything and flashing a fresh ROM like Epiphany
yes i tried puting alaxandra III fresh and got stuck in boot loop
Dont panic YOU ARE NOT BRICKED..
oK FIRST OF STOP THE PANIC ATTACK.. this will likely cause you to miss a step..
1st .. Can you boot into recovery.
if so ..
i suggest .. start from the beginning.. TALK ALL VERIABLES OUT..
Format your SD CARD with a android phone or a sd format utility.. i use the one from pnys website..
re download the rom you wish to flash . To the SD CARD WHILE its in your computer i believe is best..
put the sd card in your computer..
boot into cwm or ra
wipe as usual
format partitions NOT THE sd card
Flash the newly downloaded rom..
reboot recovery .. go back to wipe menu
re wipe. as usual..
Reboot the tablet and set your google account back up. the above will KILL ALL OF YOUR DATA...
THIS IS HOW I Get out of trouble when i toast something.. I ALSO not only backup everytime i take a backup. i try to restore it to be sure its working correctly.. and i push it to my personal ftp site .
good luck...
ok i will try this thx ill get back....
also why did my backup not work? there would not be an issue if they had worked?

This is something i always do..it insures that the rom is clean and Fresh. sometimes if you do not take this step you will have ghost directories in /sdcard. directories that did not get deleted. why this happens i have NO IDEA..
Im just a average user that follows what i read.
ok it happens so fast i cant read what come after but when i wipedata/factory i get the same
error removing /data/data/com.google.videos/cache/-1755362040.cacheError while formatting/ data
then it says something else 2 lines i think then it says done, not sure what that means ill try and keep going and see what happens
and wipe cache says e:unknwn volume for path [/sd-ext]
nope it did not work.
back to the forceclose pop up
i didnt get the set up stuff.straight to the rom. im getting notifications in bottem left like new email and wifi availible. shouldnt i get the set up ie. google account time zones and such?????
what ever that error is, its stuck in the system somehow
and one more thing i noticed.... there was a volume error i mentioned in a past post. well when im sitting here stuck with force close pop up, the volume is the only thing i can get access to. i can mute, vol up and down.
everything else is behind the pop up
http://forum.xda-developers.com/showpost.php?p=20680452&postcount=137
im kinda lost with the sd/ext error.. you might try the above.. i think this is how you rooted to begin with... via your computer thru adb.. or you could ask in the recovery thread . the ra recovery thread talks about a similar issue not sure its the same..
wish i could do more but i would get some clarification before you proceed .
so sorry i cant do more..
oh no............. i feel that panic

Hey, trying to put Alex III back in?
Ok, you need to tell me which Recovery are you Using? Thor's CWM? Or RA Revamped?
If you're using CWM, you should go to wipes, and do all the wipes (data, Cache, Dalvik,System if it has it also, not sure if his new version has it or not) Then goto Mounts and format;
1. Format System
2. Format Cache
3. Format Dalvik
4. Format Flexrom
Install Rom.
If you get stuck in animation loop, reboot back to recovery and do wipes only, then reinstall the rom.
If using RA Revamped 3.15,
Wipe;
Data/factory reset (you shouldn't lose any data)
Dalvik
System
If boot animation, go back to RA Recovery
Data/factory reset
Dalvik
I have RA Recovery down to a fine art with this rom.
Should get you hooked up.
thanks moscow
im past boot loop.
when i wipedata/factory i get the same
error removing /data/data/com.google.videos/cache/-1755362040.cacheError while formatting/ data
then it says something else 2 lines i think then it says done

"wipe cache says e:unknwn volume for path [/sd-ext]" is normal, don;t worry about it. But the other error, is corrupted data I believe.
Are you using Thor's CWM Recovery? What version?
or Do you use RA Revamped? What version
It sounds like you have some very corrupted data in there.
If you are using Thor's CWM. And his recovery only;
Here are the steps to completely wipe all internal data. And give it a clean internal system (according to Thor)
Note: Optional Formatting.
If you really want to remove EVERYTHING in Internal Memory, at this point, go to Backup and Restore. Select "Toggle backup and restore of internal storage (/data/media). Enable this setting by selecting it. By default, it is disabled. Then proceed to the formatting steps. This will format the Entire Internal Memory when you proceed.
Note, this will format EVERYTHING in internal memory (not ext sd card)
Select Go Back, Goto Mounts and Storage
1. Format System
2. Format Cache
3. Format Dalvik
4. Format Flexrom
After you reboot, I believe it resets back to the defaults.

Oh, and once you are done, try to install the rom with the normal procedures. It's quite possible the rom on the sd was corrupted, so you may want to re-download it again if you have the same error.
IF you are running RA Revamped Recovery, then you may want to contact Drellisdee at his thread;
http://forum.xda-developers.com/showthread.php?t=1459821
He knows the procedures to do the same. I would tell you, but it's a tricky process, and he knows more about his recovery than I do.
One more note, if you have an extra SD card, even a 2gb, I would format that to FAT 32, and also copy a rom to it and use it. (remove all doubt)

cannot delete from from internal sdcard

I searched but could not find the answer. I'm sure it's a simple fix, but I am a semi-noob.
I've been trying to find the right rom for me and I installed cm10 with no problems.
After that, I tried cleanrom v1.1, but it would not boot.
Since then I cannot write or remove files from internal sdcard.
Can someone point me in the right direction to remedy this situation?
can you not remove from it when you are booted into the rom or when u r on PC ?
format it and do data reset, wipe cache in recovery, flash the rom afresh .

I was unable to remove files when booted into the rom. I did not try from PC.
Formatting the internal sdcard did the trick. I wasn't sure if that would be destructive.
Thanks for your help.
formatting storage solves 60 percent of most of our small time problems, even for symptoms like rebooting / freezing etc
but keep a back up

Partition damage? Not sure whats wrong...

Hey all,
I have an S4 i337m model. I've installed a custom ROM that is essentially a rooted stock ROM (I do not remember the exact build/version of the ROM). I realize having this info would be useful, but at the moment, I cannot access this info.
While running this ROM, everything was fine. Last week Friday, I attempted to install FoxHound 1.6. Had to play around with the installation options, but I got FoxHound to work. However, I need to get back on my old ROM as I needed some files that were deleted during the FoxHound install. So I wiped my phone, and restored my nandroid backup of my rooted stock ROM. again, everything was fine. No issues.
Here is where the problem is; after restoring my rooted stock ROM, I could boot into the phone and access the files needed. However, when I reboot/shut down phone, upon restarting/powering up, my phone is stuck at the 'Samsung Galaxy S4' logo right after power on. So, I boot into recovery (the latest version of TWRP) and I navigate to 'file manager' to take a look at my storage/files. And this is where I believe the issue to be; I see virtually no files at all. I can see many folders/partitions, but there are virtually no files anywhere (i.e. the system and data partitions are empty). I am assuming this is the reason why my phone doesn't boot past the Samsung Galaxy S4 logo. Now, when this happens, I wipe my phone again and restore my working nandroid backup. Everything works fine. I can get back into Android without issues. Until I reboot/power off my phone. Then this happens all over again.
I believe I may have damaged(?) the partition(s). When I installed FoxHound, I also installed an option during installation titled 'EXT4'. I know linux uses ext2/3/4 partition tables. Did I damage my storage/partition by installing EXT4 from FoxHound? Do I need to repartition my phone via Odin PIT file or something similar? Am I totally wrong with my analysis? Any help/advise/insight would be very welcomed.
Thanks
Additional info
Baseband: I337MVLUAMG1
Build number: JDQ39.I337MVLUAMG1
ROM: Rooted stock ROM 4.2.2 (with some bloatware removed)
While my phone was in the it's 'logo stuck' state, I entered into TWRP and selected the Wipe option, then Format Data. I must select 'Format Data' in order for my phone to work on it's next boot. Manually formatting System, Data, etc... will not allow my phone to boot up at next boot. And, my phone will only work on the next boot. If I power off/restart phone, it will get stuck at the logo again. So my phone is only good for 1 boot up after a wipe.
And, after I restore a working backup and boot into the phone, everything works until next power down/reboot. Once I power down/reboot phone, I must go into recovery since it will not boot into Android. When I get into TWRP, I see that my Internal Storage has 0MB free and I am unable to see any files. I can see folders/partitions, but there is nothing in any folder/partition. My external SD card shows nothing as well. My external SD card however is unaffected as all the data is still there once I get into Android and look around.
Also, I just restored a backup I had before I was having this issue. After restoring and rebooting, the same thing happens. I get stuck at the 'Samsung Galaxy S4' logo.
So I'm guessing there is some partition troubles here. Maybe I'm wrong, but I'm scratching my head as to the cause of this problem.
It could be some hardware issues too. I'd Odin back to stock and see if the problem persists. If it does its hardware.

I thought the same thing. I'm downloading the stock ROM now and will give it a try.
One other thing I noticed during my last restore/fix attempt... After I perform a wipe -> Format Data (from TWRP), I notice that it reverts to my rooted stock ROM without me restoring anything. So, after I do a full wipe/format, and reboot my phone immediately after the full wipe/format, my phone will boot into the rooted stock ROM. I thought that wiping/formatting via TWRP totally cleans the internal storage of all data. So how can I be booting into any ROM after a wipe?
Unless I'm mistaken in my thinking and the full wipe/format option in TWRP just reverts back to the stock ROM I had installed prior to installing further custom ROMs?
If you wipe system and data there shouldn't be any rom it would boot. Don't try that though unless you have a nandroid because it shouldn't boot
What version of twrp ate you using?
Do not format data in twrp.

I hear ya... I have several nandroid backups. All work (minus this 'stuck at logo' issue I am having). I am using the newest TWRP version 2.6. It's very strange... after I perform a full wipe, I am able to boot into my rooted stock ROM that I flashed shortly after acquiring the phone. This was a bit over a month ago now. I do not know how this is possible.

Use twrp 2.5.0.2 or cwm. The newer twrp has issues.

Is TWRP 2.5.0.0 ok to use?
Ok... It's really starting to look like my partition table has been damaged. Every time I flash a new ROM or restore a nandroid backup successfully, and then restart my phone, I get stuck at the S4 logo. Upon starting recovery, my internal storage reads 0MB free. It seems like my partition table is becoming corrupt after a reboot, or it has already been corrupted.
I tried flashing the stock ROM for my phone (I337MVLUAMDJ_I337MOYAAMDJ_I337MVLUAMDJ_HOME.tar is the one I used), but that didn't help at all. After installing this stock ROM, and I go into stock recovery, I get an error: E:failed to mount /data (invalid argument).
This really is looking like a partition problem. Is there some way to re-partition my phone? I remember a PIT file was used to partition my old Galaxy S i9000. Is there a PIT file for the S4 i337m?
I would also like to try CWM but I am having a hard time finding a ODIN flashable version.
I wouldn't mess with a pit file and I haven't seen one anyway. It's sounding more and more like your memory is bad. I'd keep it stock and see if you can get an exchange on the phone under warranty.
Further investigation has lead me to the culprit... sorta. It's my /data partition that is screwing everything up. If I format /data and then reboot, I can get into my phone. But if I reboot again, then my /data partition becomes corrupt and my phone hangs at the S4 logo. And then if I go into recovery, I can see that my internal storage is at 0MB free.
However, after formatting/restoring /data partition and rebooting into android successfully, everything works fine. If I reboot from this point and enter recovery, I am still able to see my /data partition and files. At this point, everything seems to be fine. Once I reboot out of recovery and let the phone boot into Android, I get stuck at the S4 logo and my /data partition screws up/becomes corrupt. It looks like my /data partition is only becoming corrupt after the 1st successful boot into Android. If I enter recovery after the 1st successful android load, I am still able to see all files and partitions. It is only trying to load android after the 1st boot that my /data partition becomes corrupt. Very strange...
So, I can always boot into my phone as long as I format my /data partition prior to loading Android. Anyone experience this before? Any ideas? I realize my memory may be damaged, but I'm leaving that as a last resort possibility since my phone was working fine up until I started installing FoxHound with the EXT4 option as well as installing 1 or 2 of the kernel's FoxHound provides. Namely Adam kernel is the one I tried.
All good... I think/hope
Well, I think I got the problem solved. After toying with this thing all day. It seems like TWRP 2.6 was the problem in some sense. Looks like TWRP 2.6 does not format the /data partition correctly. I had to get restore/install a working ROM, boot into my phone and install ClockworkMod Recovery via ROM Manager. I then used CWM to format /data. Once I did this, and loaded back into my phone, and went through the setup process since /data was formatted, everything was working fine. I just rebooted 5 times and shut down twice and my phone booted back up into android without issue.
So as one user in this thread had mentioned, formatting /data with TWRP 2.6 was the problem.
Hope this helps others avoid a similar issue.
Thanks everyone for all the help. It pointed me in the right direction.
Glad you got it fixed.
I'll be giving these steps a try, having somewhat of the same problem!
i've been having this exact same problem but with TWRP 2.5.0.2 since July. Its been driving me insane and I have not been able to find any one else having this issue until now. I think i might finally try CWM instead as a last measure before I finally give up!
Try TWRP 2.6.3.1 version. It works pretty well even though it's unofficial http://forum.xda-developers.com/showthread.php?t=2262996

[Q] SafeStrap 3.71 Formatted my EXTSD card!

I have a pretty serious issue. I was trying to upgrade to the latest version of Hyperdrive, and somehow using SafeStrap 3.71 I emptied my stock OS slot (System partition size is 0, and it says no OS installed when I try to reboot). Obviously, I had put all my backup files and the new ROM on my external drive. In the midst of trying to restore my stock ROM, I tried the "Wipe" Format Data option just to get back to a fresh start. It says all "internal storage" will be formatted. I had no idea this included my EXTSD! Now I can't install the custom ROM that was on it, can't get back to factory ("no os installed"), and I've lost every bit of data, pictures, business files etc.
Any help here? I'm pretty intelligent but this is over my head. I've got to restore that data on that SD card if nothing else.
Thanks,
Matt
You are in the wrong section. Our S4 don't use safestrap. You need to be here:
http://forum.xda-developers.com/galaxy-s4-att
ps try to read your sdcard in your pc to see if the data is really gone.
