Enabling ADB on the InnoTV

[is0-mick]

On the latest version of firmware, they have changed the boot image, so you are no longer root when connecting with adb.
You get a prompt like:
127|shell@android:/ $ su
su: permission denied

I did the following to re-enable root once I found it had been disabled.

Dump the boot.img with

sudo dd if=/dev/sdb of=innotvboot.img skip=49152 count=24576
(the 49152 and 24576 are calculated from the table in the first post 0xA000 + 0x2000 = 0xC000 (49152) and 0x6000 = 24576)

I then used a program called imgRePackerRK to unpack the image.

imgRePackerRK innotvboot.img

this will then make a folder called innotvboot.img.dump/ramdisk.dump
go there and edit the default.prop file

change the following lines from:
ro.secure=1
ro.allow.mock.location=0
ro.debuggable=0

persist.sys.usb.config=none

to:
ro.secure=0
ro.allow.mock.location=1
ro.debuggable=1

persist.sys.usb.config=adb


and save the file.

To repack:
imgRePackerRK Innoboot.img.cfg
(notice the .cfg at the end)

To re-flash:

sudo dd if=iinnotvboot.img bs=512 obs=512 seek=49152 of=/dev/sdb

Re-insert SD, and reboot

127|root@android:/ # cat default.prop
...
...
ro.secure=0
ro.allow.mock.location=1
ro.debuggable=1
ro.build.root.date=Wed Jun 17 16:37:22 CST 2015
persist.sys.usb.config=adb
root@android:/ #
