Mugger · 05-22-2011, 23:10

I have a 6288 whit 6.4 FMW and want it to become a 6280 whit 3.81 or lower (found 3.7)
Is this possible whit JAF 1.92.62 Or Phenix SS 2011.14 whitout anny boxes and a usb ca-53 cable?

What is the reason for downgrading ? As I know, the latest firmware for 6280 ( RM-78) is 6.43 .

Well Dejans unlocker works whit 6280 so i thought, if i can downgrade my 6288 maby its possible too unlock it

So my original idea of downgradeing was a failure (no support for it) so its time too buy a cheep box so i found 2 JAF boxes(

) and 1 UFS box
JAF 1 a silver box 30 USD
JAF 2 a red,gray black box 30 USD
UFS Blue ufs-3 box
So are anny of theese boxes capable of unlocking bb5 sl1 phones?
and whats the differenses in them?

Yes im fully aware that its only boxes, no cables or other stuff

Jaf (silver one) can unlock 6280/6288, but you need a P-Key to use the software.
