Finally I have managed to put OS6 on my 9700 and get it to work!
whenever I tried to install any build I ended up with a warning at the end of the loading process that some cod failed to install due to invalid digital signature! and consequently "Error 200" when the device reboots!
So I disabled the forced installation of the applications: bbm; memo pad and Tasks during the OS software loading by editing the corresponding alx files in the OS installation files folder setting <required> value to false.
in effect I installed a stipped down OS and it worked. then I went back and used BBSAK to install everything else (I don't trust the desktop manager)
still I have 2 issues and I wish I hear from you guys:
1> does the operator logo; the on that appears after reboot, changes if I have installed as OS from a different Operator. the original OS5was etisalat (UAE) and I upgraded to OS6 Telus (CA) but the logo&default wallpaper is still that of etisalat!
2> did anyone get problems with GPS as it seems BB Maps & Google Maps are unable to obtain a satellites!?
