I bought my own nook color on saturday, there doesn't appear to be a factory image that can be restored. My new nook color came with version 1.01 preinstalled. Before turning it on the first time I put in nookie froyo and did a dd of all 8 of the stock partitions. Below is the zipped up .img files of mmcblk0p1/mmcblk0p5 (boot/system) from a stock untouched 1.01 nook color. I am also including the factory.zip. This should be enough to restore a bricked nook color with a corrupted boot or system partition. Many people have been able to restore to stock by just using the boot.img because after 8 failed boots it will do a factory reset.
To make this work you must have ADB working first. You may be able to get this to work on ADB Wireless, but I don't recommend it. For instructions on getting adb to work with the nook color go here:
http://nookdevs.com/NookColor_USB_ADB
To use these files unzip them to the sdcard portion of a nookie froyo sdcard, or just about any other rom that runs from the sdcard and run the following commands in an adb shell:
dd if=/sdcard/boot.img of=/dev/block/mmcblk0p1
dd if=/sdcard/system.img of=/dev/block/mmcblk0p5
Boot
System
factory.zip
Thanks, you're a life saver!

Did it fix you samuelhalff?
Yes. But I only used boot.img. Then restored to stock with 8 failed boots. Dd'ing system will also work.
If it dosen't boot, do a factory reset with power+n.

So if I put the factory.zip on /dev/mmcblk0p3 and replace the current one, when we do the 8 bad boot trigger we would get 1.0.1 flashed instead of 1.0.0 right?
Yes. And I would also do a power+n reset at the end, to avoid any problems.

shad0wf0x,
I am having the same problem with my NC not booting after a failed attempt at
re-rooting. I will tell you in advance that I am VERY tech-phobic and don't comprehend all this command-line stuff well at all.
Given your original post above, could you please explain in layman's terms EXACTLY what steps to take to restore my NC to like-new? And hopefully it can be done with just simply putting some files on a micro SD and that's it. Please let me know from start to finish how I do this. Appreciate your help in advance.
vigeh4
P.S. I know I had no business doing this, but I screwed my unit up anyway. I already tried the 8-step interrupt thing before re-rooting but with no success.
vigeh4,
First download the first 2 files, system and boot, and then unzip them. Then you need to copy those 2 files (system.img and boot.img) to the sdcard, either while booted up in nookie froyo or by putting the sdcard in your computer. Then you must have adb working on your computer. open a command prompt or terminal(windows or mac/linux) and go to the location where your working adb is and copy and paste those commands into the window to run them.
Code:
dd if=/sdcard/boot.img of=/dev/block/mmcblk0p1
dd if=/sdcard/system.img of=/dev/block/mmcblk0p5

Sorry, I am WAY confused about how to do this. This adb crap is over my head.
Maybe I just have a $250 paperweight at this point. If I mail you my NC, would you reset to "factory" for a small fee?
Thanks.
OMFG, thank you very much for these files and instructions.
I really thought I bricked it to the point of no return. I initially screwed it up when I installed Clockwork and wouldn't boot past "N", then after tinkering around some more, it wouldn't even turn on ... lol.
@vigeh
First you need to unzip those files you just downloaded. Second, you need to copy the "boot.img" and "system.img" (not the *.zip) to the "/SDCARD" folder on your SDCARD. I had to use WIFI FILE Explorer in Nookie Froyo cuz I messed up my nook so bad, i couldn't copy these files by turning on the USB Storage through the regular method. It took me days to figure this out cuz i'm kinda slow.
I hope you installed the Android-SDK on your computer already. If so, then go to the folder named "\platform-tools" on your PC - this is where ADB.EXE is located. Connect your nook and type "ADB DEVICES" just to make sure your nook is connected to the computer. It'll show up and tell you it is or not. If it is connected then do the following:
1. Type "ADB SHELL" then you'll see a "#" symbol after you hit enter.
2. Type "dd if=/sdcard/boot.img of=/dev/block/mmcblk0p1" just the way it is written by the original poster (minus the "" marks)
at this point, it usually wont say anything. Just wait a few minutes and something will pop up. In my case, it says:
"477033984 bytes <454.9MB> copied, 138.757660 seconds, 3.3MB/s"
"#"
3. Type the second command next to the "#" sign "dd if=/sdcard/system.img of=/dev/block/mmcblk0p5"
wait another few minutes til the next confirmation pops up.
4. turn off nook, remove SD card
5. Hold the N button and the Power button at the same time and it'll ask you to reset the nook to factory settings.
I hope this helps you ....
well im a tard... i did this without reading that YOU CANNOT HAVE GOOGLE APPS!!!! so anyway Im trying to get back to a stock image, but i cant figure out how to copy 700 med +/- of images to 134 meg f free space. someone un-tard me plz . thanks
I have ClockworkMod Recovery installed, and if I put the factory.zip you provided on my sd card and use the option 'install zip from sdcard' will that in fact install factory settings on the nook?
I tried to do the 8 failed boots, but cannot get it to work with this installed.

How do you get to your "working adb?" I'm probably even more ignorant on this SDK stuff that vigeh4. I have SDK installed though.

Thanks to Shadowf0x for getting ABD to work
I have a question though, if I dont have the file "SDCARD" in my SD card then can I just make a new file and name it SDCARD, and put both of the .img's into it?

I'm not sure if that will work, I guess it's worth a try, however if you replace the existing factory.zip and do a factory reset you will restore back to 1.01 instead of 1.0 if you don't already have a nc that has 1.01 on it. I saw another thread about trying to use the factory.zip with cwm, but I didn't see anyone coming back and say it worked. How to flash back to stock is found here:

You could try to mount the media partition in nookie froyo and put them there.
The partition is /dev/block/mmcblk0p8 and type is vfat.

Evening Folks,
Hoping someone can help. I've been trying to install a custom rom onto my mini pro (Any custom rom!). Done a lot of reading and have managed to root my phone but am now stuck when trying to install xrecovery and CWM.
I've put xrecovery, busybox, chargemon and the cwm zip file onto my sdcard. I've been trying to move busybox, chargemon and xrecovery to the /system/bin directory using Super Manager. But it keeps telling me I do not have enough space, even tho I have 150mb internal space free on the phone. As far as I can tell the three files I need to move are less than 1mb and I've deleted just about everything I trust myself to delete.
ALong the way I managed to muck up the google acount password and ended up resetting the phone to the factory defaults, so there is nothing on it. Currently the only downloaded apps are Root Checker, Super Manager and SuperUser.
So I'm hoping one of you fine chaps, and chapetts, is going to be able to point out the stupid mistake I'm making.
I have to escape sooon, so will not be able to reply util tomorrow. Thanks in advance.
SteveG
You realise the /system partition is seprate from the /data partition, so internal free space does not mean free space on the system partition. And did you remount the system partition yet? (This command in terminal emulator: mount -o remount,rw /system) Or you could simply use root explorer and save lots of trouble figuring out the terminal.
i would advise you to install xrecovery via aais, it is quite simple; download aais and put on your sd, download terminal emulator from the market (needs root, you are rooted you say so that is fine) type the commands:
su (start superuser, click allow)
cd sdcard/aais
sh install.sh (now you see the menu)
type 0 for installing xrecovery. phone will reboot and you're done. Download cwm for recovery.zip from xda and install cwm via xrecovery, now you can install custom roms.

Ah, no I didnt realise that. Anyway I can tell how much space in the system partition? Any reason why it should be full after a factory reset? If it is full, any suggestions?

If I do this where does the xrecovery file need to be for the install?
Thanks for replying guys. You have givne me some suggestions for the way forwards.
SteveG
AAIS is an automatic installer for xrecovery, sorry..was not clear enough apparently. You can find it here on xda (xrecovery automatic installation script or something like that) and works like a charm! No need to copy files yourself, run the script and you'll have xrecovery, afterwards install cwm via xrecovery..simple as that
AAIS did the trick (Although I had to use a magnifyng glass to use the terminal emulator. Currently waiting for the rom to finish installing.
Thanks for your help
WARNING
If your bootloader is unlocked and you flashed a custom recovery, YOU WILL BRICK YOUR DEVICE BY ATTEMPTING THE STEPS BELOW!
Description
This method will allow you to apply any ICS or Honeycomb update to your tablet, no matter what the SKU of the update. This makes it possible to switch SKU's (eg. from WW to US) or to downgrade from ICS to Honeycomb. This means non US tablets can install the 9.4.2.13 US version or downgrade to 9.4.2.11 or even Honeycomb if experiencing problems.
Requirements
root access
ADB access
Disclaimer
While this process appears to work on everyone's device, you have to assume all risks due to unforeseen circumstances and need to understand there is a risk of bricking your tablet during the update. Although someone else was successful in downgrading from ICS to Honeycomb, there has been a report of a TFP bootlooping. Everyone else has been successful in downgrading from ICS 9.4.2.13 to ICS 9.4.2.11.
UPDATE: 2 reports so far of tablets bootlooping after downgrading to Honeycomb.
Notes
It's possible OTA updates will not apply when switching SKUs. However, you can always switch back to the proper SKU once an update is available. The Honeycomb update may wipe all data so ensure a full backup of apps & data is performed (eg. by using Titanium Backup) It's not recommended to restore "system" data using Titanium Backup when changing between Android versions When downgrading to a previous version of ICS, "Launcher" will force close requiring to wipe Launcher data in the Apps menu. Voodoo Rootkeeper may not be able to restore root after updating to 9.4.2.13. The "blob" file is contained within a ZIP file contained within the downloaded ZIP file.
Instructions
1. Download one of the updates (eg. US_epaduser9_4_2_13UpdateLauncher.zip) from here: http://support.asus.com/download.asp...2&hashedid=n/a (older firmwares are available at the end of this post) 2. Extract files from within zip 3. Extract files again from the extracted zip 4. Copy extracted "blob" file to root of folder of the removable Micro SD card or some other folder 5. Through ADB shell or Terminal Emulator, run the following: (May take from 5 to 20 minutes) Code: su dd if=/Removable/MicroSD/blob of=/dev/block/mmcblk0p4
If copying the "blob" file to the SD card in the keyboard dock, use: dd if=/Removable/SD/blob of=/dev/block/mmcblk0p4 If copying it to the internal memory, use: dd if=/sdcard/blob of=/dev/block/mmcblk0p4
6. Reboot only if the following is displayed: Note: This may take up to 10 min so be patient
1068769+1 records in 1068769+1 records out 547210197 bytes transferred in 153.991 secs (3553520 bytes/sec)
7. Update process will automatically launch 8. OPTIONAL: Once booted up, root device by using Mempodroid Root or some other method that supports the new version.
8. Now install new firmware. Go to Settings-About Tablet-system firmware
Older Firmwares
8.8.3.33 US: http://dl.dropbox.com/u/8822437/Upda...er8_8_3_33.zip
we already have this In developement section. its been there for the longest time now. good info though

I know just reposted it for those that don't visit the forum often
It worked.....yes
So I have WW version and was rooted and tried to OTA update to 4.2.2 and got the red triangle.
After much looking on these threads and help from a user I proceeded to do the dplpkgfile method, copy file and command etc to cache and cache/recovery. temp unroot and tried recovery.
It still wouldnt work so did a factory reset and still no go.
Even tried manually installing firmware by placing it on an sd card, that failed as did renaming the firmware on the sd card and trying recovery
So I am at a loss.. I havent modified build.prop or frozen any apps.. Don't know what else I can try to get this thing to update.. Should I try to do full unroot with Super SU?
Appreciate any help
Cheers
I've got a cheap Chinese tablet (WM8850-MID) running Android 4.0.3 based on WonderMedia 8850 processor.
It's not rooted.
Here's what i found:
/system/xbin/su is present:
-rwsr-xr-x 1 0 0 68528 May 14 11:07 su
But I can't run su in a terminal:
su uid 10064 not allowed to su
Using adb.exe I have the same problem with uid 2000.
There is a script /system/etc/init.sh which is called a boot time, but If I modify and push it via adb it won't execute (lost execute permission)
adb reboot-bootloader does reboot the device, but it does not stay in bootloader mode and just go straight to Android.
I'm not sure where to go from here. Is there a way to root that device ?
Try ./adb root to run as root.
Use oneclickroot.

I forgot to mention "adb root" says I'm already root.
If I copy files with adb push, the owner is root, but If I use "adb shell" I'm user uid 2000.
This is a new tablet, but I'll give oneclick a try anyway. Thanks.
I've just tried SuperOneClick 2.3.1.0. It says it's already rooted because it can find /system/xbin/su, but I continued anyway. It can copy busybox (temp) but cannot change the permissions and it stops there.
Try resetting your tablet and if the su binary is stil there remove it. After resetting retry with superoneclick.

Thanks, but how do I delete it since I don't have the permissions? In case it's possible, is it safe to remove the su binary? I have no way to recover my firmware...
Use ./adb root to remove it because you will be root.After removing it reset your tablet to factory settings. It is safe because the su binary is not part of the os.
Then try rooting with oneclickroot.
Hope it works for you.
i also bought wm8850 tablet in china..can you teach me how to root in detailed its my first android device....i dont understand the other terms u are using....
Hi jallaine12gil,
I think that you should first try to root with oneclickroot. Post if it worked or not. Oneclickroot is a rooting program for android devices.
download the firmware. then find the android4.0.tgz file open it with 7zip, add the su file to system/bin folder and system/xbin manually.... then put the superuser.apk in the system/app folder then save changes.... then flash firmware from sdcard

Here's my sugestion ...delete what you have on sdcard for the root process..put the zipped file on the root of your sdcard... Download a zip extractor app(free on play store) use it to extract the zipped root file straight onto your sdcards root dont change anything then follow the instructions from there in the emulator.
I answered this in the General forum "all things ME7" thread.
The problem is that when the root zip file was unzipped, all of the files were extracted to the root directory.
You need to unzip and create the proper folder structure on the sd card - then it'll work.
