downgrading to imate rom

[turbominor]

I updated my mteor to the new ROM: 1.34.251.1 Radio: 1.38.00.10 and am having more trouble with the homeservice or no signal problems.

I want to downgrade to the imate sp jas rom but get the invalid vendor id error even if i rerun the update

any ideas how i can downgrade

I am facing a similar problem, I accidentally upgraded my radio to 1.38 from 1.21 and I want to get it back to 1.21 but I am getting the update error 260 saying it can't find my phone :S

Unpack the nbh file from the JASJAM upgrade and write onto a microsd flash as breeimg.nbh and use the custom SSPL in this forum to flash.

To be safe I'd extract just the os rom element and flash that.
