That did not work . twice .
You get it boot up but than only black screen , it does not go all the way .
I think you have to get a image that works with the chip and has 89 .
You have to flash it with DreamUP_1_3_3_12 , flashing with browser does not work .
The boot 89 in an original image , wich you use with the brower does not flash the jahar image ok .
it does not flash the boot .
I think that only DreamUP_1_3_3_12 flashes the images right .
I did some 40 different flashes on 2 v2 boxes solderd the chip in and out 20 times or so .
This is all i come up with .
But have enough of it now , it works now with openatv , the motherboards do not survive more soldering ,
had to fix one bypass already .

Did you ever put a japhar sim in a V2 ?
I have some 15 Dreamboxes 800 ( friends , family , holiday homes, give them away )
and 4 Formuler F4 turbo (and some 15 tuners in the loft , am crazy ) so not all the way a beginner . And make mistakes .

My first V2 went well , these 2 should not be a problem .
See if can find another V2 , not easy , sellers don't even know they have a V2 , the remote is the indication .
