Did you successfully boot the CWM? It should have a menu on it above a picture of Andy. When booted, it should give you R/W access.
Also note that depending on what you had on there earlier, the directory /data may not exist, so use /system instead.


Yeah, but boy was it a gigantic PITA... Man that default recovery is terrible. I got CWM on there now, so it's not so terrible but cripes...

What ROM would be the most stable on these things?

Hi, I think I just bricked my white 7" pdn.

Not sure what the FW is. I had used the pandigital fw update before, so I believe it was set to the latest.

Then I mistakenly followed the instructions in the link below w/o doing any research. So I'm pretty sure I used an older FW which bricked it.
http://www.instructa...n-Android-tabl/

I held the vol+ button and power switch until the orange progress appeared. It went roughly 25% then blacked out and unable to power on again.

The orange led only comes up briefly when I it plug in or press the reset button.

Connecting it via usb makes my pc "ding" and I can access the external sd card.

running the command "adp devices" does not detect the pdn. (I'm using win7 64. Do I need to do this on xp?)

Is using the serial connection the only thing left to revive it?


Edit: found driver from link below and now adb shows device! :)

Hopefully now you can write to the beast with adb. I'd suggest going back and reading this entire thread with special emphasis on Giant Wookie's instructions and my later ones. Download the file from Giant Wookie's post, and use adb to push then flash the 4 .img files, and you should be good to go as described above.

I've successfully talked with Win7 x64. Make sure you have the necessary S3C6410 driver installed for it to work.
You should be able to find a driver at:
http://www.the-digit...-the-Novel1.zip

No guarantee your machine will work with it. It took me 3 different computers before I found one that saw the Novel.
Once you're there, go back and read *all* this thread before trying anything. It will be worth your time to do so.

Hi RRA, thanks for checking in and helping out. I've gotten adb to detect the device, however it "failed to copy 'recovery.img' to '/data/misc': Read-only file system" just like edeboss said. So I downloaded mac1_131's clockwork recovery file MAC1_CWM_RECOVERY_C1SL20_20120224_B_PD_INX7E_ENG_6410POP.zip from post #51 (page 3) and placed it (as is i.e. zipped) in the external sd card. Held the vol+ and pwr buttons for up to a minute but the screen never blinks nor turn on.


I'm assuming you have the R7T40WWHF1 version (see the sticker on the back of the reader). If so, go back to mac1_131's earlier post and download his file MAC1_CWM_RECOVERY_C1SL20_20120224_B_PD_INX7E_ENG_6410POP.zip
Place it on an external SD card, or the internal one if you don't have an external card. Make sure you have no other .zip or .dat files on either card. Hold down the volume+ key and press and hold the power on button. Hold both for about 15 seconds (on mine, the screen first comes on, then about 13 seconds later it blinks). After that, it should start flashing the CWM file. Wait till it's complete. The next time you do this, it should boot into the CWM screen. Once there, you should be able to connect with adb and have a writable filesystem. Then you can follow Giant Wookie's instructions (as I paraphrased just above) to unbrick it.


Edit: read post #44 where Joseph Pruitt said to replace 'data' path with 'system' and that allowed the recovery.img and kernel files to be written to the device

But then I got the shell issue reported by wfutch. Downloaded and pushed the sh file from post #46 and now when I run adb shell, it says:

- exec '/system/bin/sh' failed: Permission denied (13) -


Edit 2:
unplugged the 5v adapter and disconnected the battery. waited a while, plugged them back in.
had MAC1_CWM_RECOVERY_C1SL20_20120224_B_PD_INX7E_ENG_6410POP.zip in external sdcard. held power switch and vol+ = nothing.

sometime later...about to try the FRAMEREVERT_AND_SDK7_02_24_2012_PD_INX7E_ENG_6410POP.zip file, but pc couldn't detect device when I connected the usb cable.
I pressed the reset button and held the power switch and the blue screen started up! I can access adb shell now!

so I pushed and flashed the recovery and kernel files and rebooted. now I'm stuck at the blue startup screen again.

I tried flashing with the MAC1_CWM_RECOVERY file again but the blue screen doesn't change. I can't even power it down.

I continued with Giant Wookie's post #69 and flashed the four img files he provided and rebooted.

adb shell

# cat /proc/mtd
cat /proc/mtd

had to unplug the adapter and battery to shut down.
plugged back in and finally flashing MAC1_CWM_RECOVERY_C1SL20_20120224_B_PD_INX7E_ENG_6410POP.zip
andy shows up with yellow progress bar going. fingers-crossed!

yellow bar got about 35% then the blue pandigital splash screen showed up. what now?

booting it by holding power and volume+ brings up the CWM recovery menu :)

following Giant Wookie's steps to push Nandroid into sdcard

pc does not detect device when the blue screen is on. So make sure you boot into the recovery menu to get a steady connection for adb to access device

in adb shell
mkdir -p /sdcard/clockworkmod/backup/2012.10.31

exit shell and push the 4 Nandroid files into that path

C:\adb\adb64>adb push nandroid.md5 /sdcard/clockworkmod/backup/2012.10.31/nandroid.md5
16 KB/s (153 bytes in 0.009s)

C:\adb\adb64>adb push cache.yaffs2.img /sdcard/clockworkmod/backup/2012.10.31/cache.yaffs2.img
2156 KB/s (56548800 bytes in 25.604s)

C:\adb\adb64>adb push data.yaffs2.img /sdcard/clockworkmod/backup/2012.10.31/data.yaffs2.img
2104 KB/s (19707072 bytes in 9.144s)

C:\adb\adb64>adb push system.yaffs2.img /sdcard/clockworkmod/backup/2012.10.31/system.yaffs2.img
2464 KB/s (111196800 bytes in 44.056s)

(I got disconnected once while pushing the last file b/c I wasn't interacting with the menu so it went to the blue startup screen. had to re-push it)

now using the volume up and down buttons I went to "backup and restore" and tapped to select into it and selected "restore"
but it says

E:Can't mount /sdcard
E:Can't find misc

tried "mounts and storage" to mount /sdcard but that results in
Error mounting /sdcard!

according to Giant Wookie, NOTE: the sdcard may need to be manually mounted in the adb shell using mount -t vfat /dev/block/mmcblk0p1 /sdcard

C:\adb\adb64>adb shell mount -t vfat /dev/block/mmcblk0p1 /sdcard
mount: mounting /dev/block/mmcblk0p1 on /sdcard failed: No such file or directory

should I format the sdcard since clockworkmod is expecting a partition? no.

~ # cat /proc/partitions
cat /proc/partitions
major minor #blocks name

179 8 1985024 mmcblk1
179 9 1984899 mmcblk1p1

31 4 3072 mtdblock4
31 5 204800 mtdblock5
31 6 32768 mtdblock6
~ #

sdcard is actually mmcblk1p1 so the mount command works now

C:\adb\adb64>adb shell mount -t vfat /dev/block/mmcblk1p1 /sdcard

going back to the recovery menu, I tried to restore but it now says

Couldn't open directory
No files found.
E:Can't find misc

looks like the Nandroid files I placed in the sdcard folder was not the actual external sdcard

re-pushed the files and now restoring

after files restored, I selected the first menu option to restart. this brings up the blue startup screen and seems to be stuck here.

I insert the internal micro sdcard (which was mmcblk0 - skipping steps 9 & 10 b/c it already has all the files)

I push and flash Wookie's 10,240kb recovery.img

Then I reboot getting the android and yellow progress bar. It gets about 30% and then gets stuck with the blue startup screen.

??? Help please!

I remembered writing down some information when I tried to update my wpdn when I first got it.

model no: R7T40WWHF1
power: 5v

pdc1_20120323_b_pd_inx7e_eng_6410pop
kernel 2.6.29
build pd novel 2012.03.23
device id 7020000312790613

Does this mean it was running the 2012 OP Firmware? If so, it seems I have to wait until more research is done on the 2012 OP.

Anyway, I ruined it by following an outdated article's suggestion to flash "Jackbox's second version" OP_JB_S20_10_10_23_G_PD_INX7E_ENG_6410POP.zip

Then I found my way here to recover it and did the above (previous post) in hopes to recover it. Can't get past blue screen but able to boot into clockworkmod. (similar to what Giant Wookie said in his first post. I'm guessing the blue screen is the loop issue?) Not entirely sure where it stands at the moment. Been plowing through this forum reading all sorts. Much appreciation for all the work done in this community.

I think you're flashing the wrong images. Look in the PandigitalOEM.zip you downloaded from Giant Wookie's link and look in the "dd images from ########### device" directory. Those are the images I used, not the ones in CWM-backup.

THANKS RRA!! (and Giant Wookie) :)

When I originally flashed the 4 img files, I did not have the cwm recovery program as Giant Wookie instructed so I didn't use the reboot option in the menu. (so I did it out of order and needed to flash the img files again)

bootloader.img
kernel.img
id.img
ramdisk.img


Settings say I now have

firmware version
SL20_20120224_B_PD_INX7E_ENG_6410POP

kernel version
2.6.29

Hey, I just wanted to confirm that Mac1s FW worked for me. I have the White PD Novel 7 Inch and I had a black screen from downgrading SL20 to S10. I wouldn't have done it in the first place if I wasn't so dyslexic. Lol. I flashed twice and everything seems good so far. Thanks a lot for everyones input and all the effort put in.

Have a great day guys !

Try following the exact steps laid out by Wookie. This is not a normal Android install, PD really FUBAR on this one.

Good luck with that. These tablets are terrible, and you have to be very careful as they are not the same as the other tablets. the model is very specific.

I don't know if you've bothered to read *all* this thread, but it may be worth the effort. Especially things starting around page 6.
http://www.slatedroi...e/page__st__100

Loading the CWM first to get you started with full adb, and it should only take a few minutes to unbrick the unit. If my instructions aren't clear enough, feel free to ask for clarification.
