CM9 for Coby 9740 + New Recovery

[dukkha67]

Back then I did it on windows, one of those one-click root.


No idea about the recovery. I didn't do any system dump and never got clockworked. Now I know that was such a terrible idea.

post output of lsmod, I want to see if you have nand lock on your tablet.

copy and paste below in a text document name it install-recovery.sh

#!/system/bin/sh

echo -n boot-recovery | busybox dd of=/dev/block/nandf count=1 conv=sync; sync; reboot

busybox mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak

adb shell

su

busybox mount -o remount,rw /system

in another terminal

adb push /install-recovery.sh /system/etc/install-recovery.sh

in first terminal

chmod 755 /system/etc/install-recovery.sh

reboot

Mate I tried that, after the busybox mount, in another terminal window and says...


|1st terminal|

dukkha-post@Dukkha-Ubuntu:~$ adb shell
shell@android:/ $ su
shell@android:/ # busybox mount -o remount,rw /system
shell@android:/ #


|2nd terminal|
dukkha-post@Dukkha-Ubuntu:~$ adb push /home/dukkha-post/install-recovery.sh /system/etc/install-recovery.sh

No luck yet

Are you sure you have the file install-recovery.sh created ? You might try to push another known file.

 

[dukkha67]

Yes, I even tried making it to another location, same result. I re-made the file and put it in different folders: not working.

 

[vampirefo.]

Well if you can't write to system either, then there is nothing else I can think of.

It's ok. I'll try it again sometimes but I believe the tablet is in limbo so it won't come back. Thank you a lot for you help mate!!

Shouldn't be too hard, The Hard part was porting from Aurora/Elf to Coby, I had to compile the libs, and wifi files, But This should be able to be ported to any Coby allwinner.
I am on my way to work, I work nights right now.

Anyway download the rom open the zip, delete /system/vendor /system/usr /system/etc/camera.cfg /system/lib/hw/camera.exDroid.so
/system/lib/hw/sensors.exDroid.so /system/lib/hw/lights.sun4i.so

Now replace the above files and or folders with your own 9742 files and folders.

The next thing most likely add the 180 rotation to build.prop

You then would need to edit the boot.img add your kernel. If you upload your kernel I will do it for you when I can.

From here we see how the rom runs on your 9742, if not working well add more files from /system/lib/hw

I'm gonna ask an extremely newb and possibly stupid question. Can I just drag and drop the boot.img from my dump into the zip file and delete the cm9_boot.img?

???????????????

You can do that, you wont like the results.

 

[iCameronRB]

Ok, so I take that as a no. Glad I read this in time. Was close to trying it since I always restore different boot images on other roms on my phone, I figured it would be the same for a tablet.

 

[vampirefo.]

CM 9 CM 10 and so on need a certain boot.img to work, it's different from stock boot.img.
