Linux Users, Coby 8042, Root, Recovery, Update, All Without Livesuite

Thank you for putting the work into this!

I am trying to get this to succeed with my Coby 8042, but am not successful when installing the 8042_boot.zip:

-- Installing: /sdcard/8042_boot.zip
Finding update package...
Opening update package...
Installing update...
Installation aborted.

I've tried several things, but still am not successful. I've confirmed my boot.img md5sum matches:

eda433b85d9729422a4be5889982d46d

Any help would be greatly appreciated!

Thank you!

*** UPDATE (fixed)

So the issue was that I unzipped the file, looked at it's contents and then zipped it back up. This corrupted it somehow. When I re-downloaded the zip file and then immediately installed, all worked well.

This is a newbie question, my 8042 is rooted so can I install the recovery using only a terminal app on the device?
I have Ubuntu but for some reason my adb can't get the right permissions

Yes you can use a terminal app to install a recovery. Ubuntu uses sudo so to use adb from ubuntu, you would need to do it via sudo.

Thanks, I will try then.
I use adb with sudo but I read somewhere that some steps are needed to proper configure adb.
Another question, my tablet is rooted, I only need the recovery.
My commands are these?

chmod 0777 /data/local/tmp/install-recovery.sh
/data/local/tmp/install-recovery.sh
/system/bin/reboot-recovery

Thanks for your patience

You would need to push the files first, then you can chmod them and use them.

 

[manusilvestre]

I think the recovery installed successfully because "done" appeared on the second command, but I can not enter with this command

/system/bin/reboot-recovery

 

[vampirefo.]

Verify that reboot-recovery is in system/bin

 

[manusilvestre]

The file was not in the /system/bin, so I copied it.
Now when I try to run the reboot-recovery I get a message that says something like "no permission", I tried chmod the file but it gives me an error like "Read only file system".

You need to mount system as rw before you can chmod a system file.

Many thanks now I have a recovery!
I will test your CM version for Coby 8042.

[coolwaterz]

upload your backup, I want to see if your device is different than the one I have.

If you not booting you would need to go back to stock.

Also what have you done, ie replaced recovery? replaced boot.img? replaced system?

post exactly what you have done, and when problem started.

your boot.img matches eda433b85d9729422a4be5889982d46d checksum?
