(Q) kernel development / restore - Barnes & Noble Nook Tablet

When developing kernels for this device, if you make a "bad" kernel, does the 8 restart method restore the original kernel?

Need more informations...
Where is your new kernel? on sd card or internal emmc? Did you use CWM?

Good question. Say if its on the device and/or on the sdcard. I would presume the sdcard would be a quick fix. On the device I guess would be the real ????.
And I guess it would have to be CWM.

If you have CWM installed, make a backup of the system and if something goes wrong restore it.

"lost" my CWM backups...but not really?

I think I'm too inexperienced to be rom'ing on my everyday phone. I was running Team Objection lf5 and it was great except for google voice and MHL-out. So I decided to play with CM9. Now I cannot revert back to Objection? CWM recovery menu does not see ANYTHING on my external sd card. But when I pop the card into my laptop everything is still there, including all 3 of my CWM backup dates. What gives? I installed TWRP recovery to see if that was any different but it shows my backups as blank too. (Can TWRP even see/use CWM backup files anyways??).
So if the backups are there....how do you recommend I go about regaining access to them? Thank you in advance for saving my butt!
TWRP cannot use CWM backups and when u boot into CWM u should have an option to restore from internal memory or SD card, which is external. Try that

CWM gives me something like "directory not found" both when SD is mounted and unmounted.
Might be that CM9 is having terrible seeing the external. Put the backup on your internal.

This is true, it's only navigating the internal SD. BUT I can't mount the internal in CM9 to move the backups there. I'm stuck right?
No, flash a ROM, then move the backup on your phone, them restore the backup

Got it. I'm in CM9 right now. Got USB storage "working" in that it connects, but while copying my clockworkmod folder to the internal it will cause the phone to reboot each and every time. (4x so far). I'll keep trying but this was an absolute waste of a day.
External has been wonky on CM9, just flash another ROM, preferably tw based, so you can transfer the file, then restore your backup.

Holy crap the whole problem was incompatibility between CWM and CWMtouch versions. Never would have guessed, but then again I know so little that I thought the backups they create would be compatible. Thanks everyone for your help.
CM7 was/is great on my Incredible, but it appears I am not ready for CM9 on the Note. (With the bugs in CM9 I cannot believe people are asking for CM10 already, yikes). Then again, the is on my everyday, daily driver including work phone so I need every little thing to work right.

need info

hi all can somebody direct me to modding the sgs3 as i am doing it for a friend need some steps like do i have to unlock bootloader before i root and stuff i am using hox so new to sgs3
Galaxy S3 has an unlocked bootloader, use CF-root to root it. The GS3 also uses a flash counter, if you root or flash a custom rom it will trip the flash counter, and unless it's reset with triangle away even if you reflash stock you may not be able to claim warranty.
Check out the development section for some mods (there is also a sticky in the general with some mods, and roms.)
No, Sammy bootloaders aren't locked (except verizons b*stard child S3)
Flash cf-root 6.4 via odin and you are rooted and have recovery.

soft brick please help with firmware i can flash through odin
Just go into recovery and wipe data/factory reset.
Get into recovery by holding vol up + home + power.
Try that first.

tryed it need to put a rom onto the internal memory but it not letting me mount sd to comp
And how did you delete your system?
It should boot after doing a wipe, unless you formatted your system partition.
Sent from my GT-I9300 using xda premium
think i formatted system via super wipe for arhd
Christ sake, another person f*cking themselves up because of that script.
Why didn't you follow the instructions properly? Especially the part where it says put the ROM you want to flash on the external SD?
You need to boot into download mode and flash a firmware via Odin.
Sammobile.com is where you need to go now.

am going to try put arhd on a extern sd and try flash that way will that work n i didnt put it onto exsd because i have arhd on my hox so didnt think to do that as i said doing for a friend
Ya put it on the external SD and flash from there.
Superwipe wipes internal storage, which is retarded, but that's how that dev does it.
Sent from my GT-I9300 using xda premium
How did that dev not see this coming with the useless super wipe. But yeah put a Rom on your ext sd send flash. Or flash a stock rom through Odin and start again.

That's because hox has no external SD so wiping internal SD would cause this problem every time someone used that pointless script.
Its an absolute joke of a script, it shouldn't touch the internal storage.

i must of got on the wrong board, i have the nook color, is there a similar thread for nook color
thanks
Probably but I'd suggest getting your fundamental understandings down first. Cwm is a custom recovery; the recovery is a completely separate partition on any device and that's why you can't just install an app. You could possibly find an app like ROM manager that you could install and from there flash CWM to the recovery partition.

Format internal sd card question

I'm currently using twrp with the eclipse rom. If I flash cwm then format my internal sd card, then flash back the rom, will I be gtg? Just wondering if I lose root or recovery by formatting the internal sd card. Thanks in advance!

Anyone?

You will not lose root, but you should NOT format your internal SD card, unless on the stock rom. Formatting the internal SD caused a boot loop for many S4 users on custom roms, including me, and the only solution is to ODIN back to stock. There is really no need to format your internal SD. If you don't have enough memory, just see what is taking up the space and delete it manually. If you want a squeaky clean slate, make sure you know how to ODIN to stock first.
Also know that after you ODIN back to stock you WILL need to root again.
Hope this helped.

Thank you for your reply and yes it had clarified. I'm looking to format to clean up all of the framework/mod/extra installs that I have done between roms. I know to Odin back to stock and all of that. Thanks again!

Please excuse, not pertinent to OP's problem.

Returning to stock ics from cm10.2

After trying cm10.2 I decided to go back to ICS, it appears that I now have two lots of directories some in root and others in 0 directory.
Is there a way I can use Odin to reformat and put all back in its place? Di I need a PID file to repartition back to ICS partitions.

No, your SD card is messed up due to the jb 4.2+ file system. If you don't wanna waste time moving them to the correct places, backup what you need to your computer and format your SD card in cwm recovery. If you do not want to format, then move all your files out of the /0 folder to /data/media(which is the SD card partition), i.e. /data/media/0/blabla to /data/media/blabla.

Thannks for your help. I ended up formating all, using Odin to reflash stock, reinstalled root and cwm then used my previus backup.
Thanks for your quick response.
