Hello.
I used the ubuntu restore from AdamOutler. It worked like a charm to restore my borked Nook tablet. But for what ever reason it picked up a serial number that doesnt match the one that is registered to me and my tablet. Is there a adb command or something along those lines that i can restore my serial with? I changed the serials via root explorer but it always defaults back to the wrong serial. I know it must be something I did along the line of trying to fix it but it bothers me it doesnt match to my account. It wont let me register it again. Thank you for any help...

Since no one has answered I'll give it a try. The place I find the serial number is
/rom/devconf/SerialNumber it is 16 bytes and permissions are r--r----- or
440. Since you didn't say where you were making the change this may not help.
also for info you will find /system/xbin/setserial hope this limited info may help.
Good luck!
Forgot something. I believe you can register multiple devices with google and use the same account. Mine is registered two different ways. I am registered as
Bn Nook Tablet
and
Barnes&Noble BNTV250
both are the same unit just different builds.
I'm glad im not the only one that this happen to there nook.
i sent Adam a PM last week about it and he told me that he will be making an app for that so let's hope he didn't forget.
In the mean time any help will be greatly appreciated.
Hello again,
I found two places where the serial is stored both in the rom folder. One is the "Serialnumber" file and the other is label "deviceID". Changing both will not outlast a system reset. There must be a hidden backup file where this number is stored also.

I tried this method, but for some reason, I kept getting errors when trying to write from the unmounted SD card with DD, and, when trying with the device mounted, it would continue to write the .img file, (3-4 gig before I realized why it was taking so long.)
However, once I had the "ROM" sd card, and modified the files as necessary, I booted a CM7 SD card with my nook, installed one of the many "Root" filesystem managers, and replaced the edited DeviceID and SerialNumber files on my Nook's internal ROM.
This worked -- to an extent. B&N's default software now shows my proper Serial #, however, my B&N will still not pass registration.
I'm thinking that perhaps there's something more to the registration process, MAC address perhaps?
((UPDATE))
So, I took the plunge, cracked open the back of the nook, and found the MAC address on a sticker inside, handy that, eh?
However - This still will not pass B&N registration, so there's something that I've managed to mess up beyond that. I'm guessing this particular NT will never be able to use stock ROM's again. Oh, well, not a huge loss IMHO.
((END UPDATE))
I'm probably not going to poke at it further, as I dont acutally plan on using B&N's default software, I purchased my NT with the express intention of rooting. My only worry is warranty, however, I purchased the Best Buy "Accidental Damage" warrenty, so, if it does break. I just need to "drop" it so the screen cracks! LOL!
Nook Tablet Serial Number Restore & MAC Address restore
Thanks to all for the help with repartitioning/rebuilding Nook Tablet. Here's my input to help others on their way.
Serial Number and MAC Address restore.
You will need to install a hex editor to your laptop - one like "Free Hex Editor Neo".
We will find every instance of the serial Number and of the Mac Address in Partition 5 and change them to the correct values.
This also will automatically correct the DeviceID.
Write down your incorrect values and your correct values for Serial Number and MAC Address
Now we will modify an existing rom image for Partition 5
-if you have an existing image for Partition 5 in your laptop make a copy of it and put it in C:/download.
. -skip to step 9
-otherwise do the following:
Get the image for partition 5 from your Nook Tablet and copy it to your laptop.
1. adb shell
2. ~# mount sdcard
3. ~# dd if=/dev/block/mmcblk0p5 of=/sdcard/blk/mmcblk0p5.img
..-this copied the rom image to the sd card. It is about 48MB.
4. ~# exit
5. cd /
6. adb pull /sdcard/blk/mmcblk0p5.img /download/mmcblk0p5.img
..-this copies the image file from the SD card to your laptop. Places it in the C:/download subdirectory.
7. adb shell
8. rm /sdcard/blk/mmcblk0p5.img
..-this deletes the image file from the SD card
Edit the image file
9. Open Free Hex Editor Neo
.......-file, open file, C:\download\mmcblk0p5.img
10. Search for the old incorrect value for the serial number
11. click on the right side of the hex editor (on the ansi script)
.......-do a replace
...............-type in correct serial number
...............-replace every instance of the serial number in the file
12. Do the same operation to find/replace the MAC address
13. save the file. remove the “.img” file extension from it.
14. put it on the sd card in the root directory (either push it or place the SD card in your laptop)
15. adb shell
16. ~# mount sdcard
17. ~# dd if=/sdcard/mmcblk0p5 of=/dev/block/mmcblk0p5
18. ~# exit
19. remove sdcard, reboot internal.
Cheers.

Hi all and hope your okay,
I have an android 4.0.4 dual sim chinese tablet that i would like to root. I would like to know if there is a working one click root android app or a pc software that would root this device of mine?

I cant thank you enough my freind, this guy femmy4us is a superstar a truely considerate helping genuine kind person. Now the Dual sim MTK6575 Android 4.0.4 tablet phone with the build number: Alps.ics.mp.v2.2 can now be successfully ROOTED. I will post detailed info. on how to root this device in a moment, NOTE: this method well may work with other Android 4.0.4 devices but has not yet been tested. Please inform us all if this trick works for your device and state the device and its build number etc.
MTK6575 Android 4.0.4 build: ALPS.ICS.MP.V2.2 OneClick ROOT Method
This is a modified Haipai I9220 root method used to ROOT the MTK6575 Dual Sim Android 4.0.4 chinese tablet phone with build number ALPS.ICS.MP.V2.2.
NOTE: This method may well work for other Android 4.0.4 devices but has not been tested.
This is a ONE CLICK root method but needs setting up before use.
Before using this method please make sure you have your usb cable driver installed and working! (search the net for MTK65xx usb driver on google if you dont have it already)
First of all Download the attachement file Android 4.0.4 mtk6575 Alps.ICS.MP.V2.2 ROOT.rar and extract it to you system using winrar. Then
1. Go to your device settings and turn OFF usb debugging and connect the device to the pc using the cable and select "Turn on Usb Storage" on your device when the prompt appears.
2. Now your internal memory and sd card should be mounted on your computer as drives e.g F:\ and G:\ so you should be able to access your devices internal memory and sd card as drives in my computer or windows explorer, go to your devices internal memory drive on widows explorer (NOT THE SD CARD DRIVE) e.g the first of the two drives and
3. Locate a folder called ‘ data’ (if its not already there create it) and open it
4. Create a new folder inside 'data' folder and name it “local” . Remember it is without apostrophy
5. Open the local folder created and create another folder inside the local folder. Name this folder “tmp”
6. Open ‘Root- without- unlock- folder’ (It is in the file that you downloaded and extracted to your hard drive) and copy both “su.file” and ‘superuser.apk’ files to ‘tmp’ folder you created on your devices mounted internal memory drive.
7. Now turn off usb storage on your device and unplug your device
8. Go to settings, developer options, make sure usb debugging is checked this time (ON)
9. Plug in your device again (it may also be wise to enable "stay awake" option in developer options so your screen wont switch off and you will be able to see whats happening on your device).
10. Open Root haipai I9220 folder. (It is in the file that you downloaded and extracted to your system)
11. Double click root.bat and carefully follow the on screen instruction
12. After it is completely done and your device is rebooted for the 3rd time, there will be a prompt to allow superuser installation on your device because the option will come up on your device after restart, choose accept or allow and thats it your device is fully rooted!
To make sure your device is rooted you should now see a new app called superuser in your device.
NOTE: Make sure you dont unplug the cable halfway during the root process or you may brick your device!!!!
All thanks and credits go to the original developers of the programs and to femmy4us for bringing it to us and sharing it with us.
ENJOY!.

It's been confirmed working only on the build number ALPS.ICS.MP.V2.2. I havent heard from anyone else reporting its worked for them or it hasent worked for them on their device so you may well go ahead and give it a shot it may work for you aswell since its Android 4.0.4 with the same file structure.
If you do go ahead and give it a shot do please remember to give us feedback and make sure you follow the instructions carefully!
V1277 or V12 or Starlight Dou Chinese Dual SIM Phone
I have this lovely Dual SIM Chinese phone which I would like to root for several reasons. I am told by a Chinese correspondent that it uses either the MTK6575 or the MTK6577. The build is E1911_V77_BAOL_G20_20120813. I suspect from the build that it is the MTK6577. I am having an issue with Play Store only showing free Apps and I would like to fix that. Also, I would like to fix the red underline (incorrect) English words that is showing while I am using the android keyboard.
Do you know of any specific Root script that will work with this?
And in you instructions you mentioned the folder /data, however, on this phone that folder is a sub folder of Android folder. i.e. android/data. Will I need to rewrite the runme.bat to reflect this path or make a folder /data?
Thanks
P.S. The phone is called the V75 or V1277 or the Starlight Duo on this website Lightinthebox.com

I couldnt find any information on your tablet my freind, Is your android device android 4.0.4? You you may well try what you are saying and it may work. Personally i am only a messenger passing on the information and dont know anything about android programming.
It looks like this method will root most android 4.0.4 tablets with the same file structure.
Thanks alz_uk, Your guide worked for me. Much appreciated.

It is really a phone although I don't think that makes any difference. Yes is it is an Android 4.04 phone.
Thanks
I used it on my friend's Chinese knock off Htc 6" screen phone running 4.0.4 and it worked with no problems.
I've just rooted yet another android 4.0.4 phone with this technique. Remember if there isnt a folder called data on your phones internal memory then creat it and follow the instructions in the first page of this post and you should be okay.

Hi all, who know, where to get the firmware on my phone GT-I9220?
OS: Android 4.0.4
Model: GT-I9220 5-inch MTK6575
Kernel Version: 3.0.13
Build Number: ALPS.ICS.MP.V2.2
Custom build version: L207.MTK6515.2012_09_10
Hello everyone, i recently purchased one of these from newegg at a reasonable price, but I can't seem to find rom's for them anywhere. Does anyone have any ideas on where to look, i've been hunting on google for hours. It's currently running 4.2.2
Kernel 3.0.36+
Firmware: CT9706_RK610
Im not sure what else to do. I would hate to have to stick with stock considering it's a little laggy with the junk that they piled onto it. Not to mention i know it has the chinese OS installed on it. Luckily i WAS able to root it, and even get cwm installed on it, but i have no rom to flash to it as of yet. Any help is appreciated, thanks!
Soft Bricked Taipad 10s
I have this tablet, and was able to root it, and all was fine until I realized that it was not utilizing the Nandflash. The internal storage was full, and the Nand was empty (ish). SO i decided (as a newb) to pull the boot.img, edit the init.rk3066.rc and attempt to re-route the emulated storage to /mnt/sdcard. Recreated the new_boot.img, and pushed it and cat to mtdblock2 as i got it..(correct base address) - and reboot takes it to recovery. over and over.
I am looking for a rom that will work, from what i find CWR and CWM are a no go due to stopped development, but im still searching. There must be a similar tablet somewhere.
Oh and b4 the softbrick i used to get adb shell cmd line "[email protected] #" or something like that - now i only get "#" - so i could not cat the original boot.img - yay fail.

Do either of you still have the original firmware for the Taipad 9X? I've essentially bricked mine by loading an incompatible firmware and would love to get back to the original.
I'd be willing to pay a small fee to get it.
This has been posted elsewhere on XDA however it was suggested that this would be a better location to post so here goes:
'Good day all,
I have the above tablet which has been bricked . (We sell these and a customer has returned a unit to claim warranty so I am not 100% sure what has occurred to make the device what it currently is.) Basically I have another identical unit and have created a backup image with MTK Droid Tools. However when I try to load this image with SP Flash Tools I get errors. These state that the image I have is not correct (as it is from an identical unit I can safely say this is not correct) to the device storage not being available. The second error is the one I believe may be the problem. Is there a way that the internal storage may have been compromised and if is is there a way the storage can be fixed?'
I have tried to study the posts relating to partition dumping but am simply not bright enough to figure it out. Is there a way I can make a 'ghost' image of the working tablets partition table and then tranfer that to the bricked unit?
Thanks in advance for the help and time.
Alternately is anyone able to confirm a partition backup and restore tool?
Hi all,
I'm quite new with android and this explains why I'm here asking for help and direction to solve a problem. I've a chinese phone based on MT6577 hw; it's branded ORDRO P550 4.1.1. Well, months ago I was able to root it but after some months it started to be unresponsive and very slow. Perhaps because I moved some software from ROM to SD in order to get more free memory. In fact, MT65xx comes out with only 512 MB of ROM/RAM. So, I found and application named MT65xx_repartition and I decided to check if it did what it promised. Basically, it claims to be able to repartition the internal memory, using phone's internal memory to increase phone's RAM.
I made a backup of what I needed and I was able to find a stock ROM of the same model from a web site.
After running the repartition program my poor phone did not start up again; it only showed the small robot wit a big exclamation mark. OK, I thiught, I've the original ROM.....let's re-flash and learn something new. After several attempts to install USB drivers on my virtual Win7/64 box I was able to re-flash the ROM again. Et voila'....it was reborn but, alas, a little bit handicapped.
First of all the IMEI was wrong or not existent so I got no carrier and secondly, the camera didn't work at all.
For the IMEI issue I was able to fix it thanks to Mobileuncle Tools (fortunately I made a backup of IMEI before proceed) but I could not find a solution for the camera.
I checked and googled everywhere and I think that it could be a driver issue...something related with libcam*.so files but I have absolutely no idea how to fix them; do I need to recompile the drivers? I checked init.rc file but I found no evidence of libcam*.so modules nor any insmod instruction to load them. I'm not really familiar with linux; I'm moving my first steps with it and the only complicate thing I did was to recompile wifi drivers for my Debian Virtual box.
Here a partial list of phone's details collected by Mobileuncle Tools:
CPU
CPU ARMv7 rev 0 (v7l)
Hardware MT6577
Kernel
Linux Version 3.4.0
OS
OS brand ORDRO
Model P550T
Bootloader unknown
Prouct e1901_v77_gq2002
Display e1901_v77_gq2002_2013.03.25
Release 4.1.1
fingerprint alps/e1901_v77_gq2002
MTK Build
.platform = MT6577
.chip_ver = S01
.wlan.chip = MT6628
The main difference between this ROM and the previous one (for completeness I forgot to download) is the ROM size; now is 878MB (?) instead of the previous one that was 493 MB.
Thanks a lot for any support or direction you can give me; I'm looking for a set of instruction to solve this problem and learn something new.
