CMP741E Complete Nandroid Backup

[c19932]

So I downloaded 3 compatibility zips from here: [rom] Unofficial CyanogenMod 9 for many AllWinner A10 tablets - xda-developers and looked through them.
In all 3 zips, they flash "script.bin" and "script0.bin" into the /bootloader folder of the tablet ("/dev/block/nanda). I have really high hopes that this is the part that's missing!

if possible, could you please make a dump of your nanda, or provide copies of your "script.bin" and "script0.bin" from your /bootloader? I am not sure how to put them into my tablet, but I guess I could put them into one of those compatibility zips and flash it.

If this does fix touchscreen/g-sensors, that means a compatibility zip for cm9 or cm10 is possible =)

Good looking!

So while doing some more searching I found this information here:
How to restore your tablet from the dump !

Here is Nanda which should be bootloader.img
Dev-Host - nanda.img - The Ultimate Free File Hosting / File Sharing Service

---
I will make the rest later today... CWM 5.5 doesn't have ADB and I think we'd get a better IMG if I made the dumb via CWM so I will try to install CWM 6 later and see what happens.

FYI dump was done via:
cat /dev/block/nanda > /sdcard/nanda.img

---
If you read the link about restoring, you can probably use the A10 Dump I made before
http://d-h.st/CKF It has all the files they ask for.

Verified that the bootloader.img from A10 dump and from ADB dump have same MD5.

ok... so I restored bootloader.img to nanda, and...


IT WORKED BABY!!! my touchscreen and rotation sensor both work! Thank you mastermind. I could not have done this without you. I am going to try flashing cm9 on it along with the old bootloader and touchscreen/gesensor drivers to see if it works =) Thanks again

c19932/ mastermind278 could either of you outline the steps in one post so I and other newbies can follow along??

[mastermind278]

Glad it worked. Yes, this will hopefully open up new doors to CM9 and CM10.

I recommend first trying CM9 (ICS drivers should work that way).

Now that I know it can be restored I can once again start playing with the CMP741e without fear of bricking. When I was developing for the Motorola CliqXT I ended up bricking the touchscreen on it [nothing could bring if back] due to some silly driver messing things up, and I didn't want to once again be in the awkward situation of a nonworking touchscreen.

how far have you gone through? are you able to boot into recovery? please clarify your current state, thanks

1) I downloaded your 4.03 file in a previous thread and successfully flashed it to the unit (livesuite). The unit boots up all the way without touchscreen.
2) downloaded the recovery files (cwm_recovery_6.0.1.0_a10c_28072012.zip)
3) pending: I have to download ADB to push the recovery files using the commands you had specified. (new to android debug bridge, will have to figure out how to use it and push the files). I assume after this step I can boot into recovery.
Thats as far as I got.

mastermind, do you know know to repartition /system to bigger size?

[mastermind278]

I am thinking you could possibly format /system again, and then push nannd to it and see if it will go through?
No idea if it will work though... chances are it will not.

Hopefully someone else can chime in!

[c19932]

ok thanks mastermind. I saw that you made cm10 worked for cmp741d. have you considered making it work for cmp741e as well? that would be great.

I just tried loading drivers and such and it did not work for me when it comes to cm9 or cm10
