Hi!

This is my first post on this site an im looking for help.
Serached for a solution on many sites but the most of them is either dead or mising pictures etc.

So, I decided to RGH a Jasper console that I had laying around.
This was my first attempt on RGH, i´ve flashed several consoles but never RGH'd.

Using Coolrunner rev. C and JR Programmer v2
Soldered everything (with flux, experienced in soldering), looked good, but then, sh*t happened!
I somehow got stuck in the yellow wire when connecting the psu and ripped off the solder pad completely :(.
Searched the net for a solution to this and found some french post showing an alternative to the FT6U7-point. http://www.gamergen.com/tutoriels/points-alternatifs-coolrunner-fat-13053-4

So, I managed to get an extremely good trace soldering (as I said, used to solderng tiny things) and its not interferring with any other traces or points.

Hooked up psu and tried j-runner.
Got the error code 0x00.

Measured voltages and ohm and got following results (psu connected, not JR v2)
3.29v
3.29v
0.4v (154 ohm !?)
0.02v pwr off 1.07v pwr on
0
3.3v


Is the shielded cable the problem with its high resistance??

Updated driver etc with same results.

The console boots up and operates as normal otherwise.


Would really appreciate an answer :)
Thank you //Victor

Have u installed the drivers for Jr programmer.Also look up rgh1.2. It will give u better boot times and it has different post out point.
Pics of all soldering will help also.

Thank you for your quick reply!
drivers are installed correcty.
As a noob on RGH is a f-ing jungle trying to understand everything!
RGH 1.2 really seems to be a great alternative, didnt know I could do that with my chip, I was so focused on RGH 2.
Will probably try the 1.2 solution tomorrow =D
