Model - Callbar A1
Android - 2.3.5
Kernal Version – 2.6.35.7
Software version – 2.3.001.P1.12065
Hardware version – P1
CPU – SC6820 (1 Ghz.)
Screen – 3.5” HVGA

I tried several methods such as DoomLord, SuperOneClick, UnlockRoot, Z4Root to root the phone but none worked.

Tried ADB to manually root the phone through commands but almost every command returns – “Permission Denied” or “Read Only System”. However files su, SuperUsr.apk, BusyBox were easily pushed into /data/local/tmp. Further steps like making local.prop and onwards could not be executed and returned above stated errors.

Also tried modifications by putting update.zip on SdCard root and running Android Recovery System but this method also returned error “Signature Verification Failed”.

Tried Nautilus on Linux Mint with OpenSSH while running DroidSSH on the phone but could not mount device by any means.

Scanned my device with ‘X-Ray’ app which reported that device or firmware I am using had been patched and is not vulnerable to any of the exploit available at the moment.

I desperately need rooting to remove pre-installed bloatwares and applications to free internal memory which is very less. I am trying to root phone for the last several days but every method has failed. Can any one help???

I have attached PDF file containing complete details of System Memory Map, MTD Tables, Symbolic Links, Directory Permissions and File Permissions of my android phone. I hope some one having knowledge of android system can help me by suggesting custom exploit after going through these details.
