SB5101 flash not detected

[D3m0n]

Out of curiosity , can you connect up the 5100 you have and see if that detects ?

 

[Kris]

I don't have it here with me so I will try later tonight.

 

[D3m0n]

I find it hard to believe that there is an issue with the board itself , if you have a multi meter you should be able to check the continuity of the pins from the board to fcusb

 

[Kris]

I have it. Will check

 

[Kris]

Ok. It's all good with continuity

 

[D3m0n]

Can you now check the voltages on your fcusb pins and then the votages on the pins on the board

 

[Kris]

How do I do that?

 

[D3m0n]

On the modem just connect power then with your multimeter check the vcc on pins 1,3,5,7,9 whilst grounding it , similar with FCUSB just connect usb and then check VCC on pins 1,2,3,5,7 obviously both devices are not connected together when checking the relatice voltages

 

[Kris]

Board all pins about 16VAC , FCUSB about 3VAC

 

[D3m0n]

On the board pins 1,3,7,9 should all be about 3.3v and nothing on pin 5

 

[Kris]

Not sure if this is correct but my power supply says the output is 12V but if I measure with mutlimeter it shows me 25V

 

[D3m0n]

Sounds like your multimeter needs re-calibrating

 

[Kris]

Give me a second. I will test it on adjustable power supply which is calibrated by professional company

 

[Kris]

I used second multimeter and it shows me 2V on the FCUSB

 

[Kris]

Later tonight I will check with the right power supply and SB5100 and let you know

 

[Kris]

Do I connect pins on the SB5100 the same way as SB5101?

 

[Kris]

Hey I got the SB5101 connected again. Don't know why but it all work only if I switch to +5V power on the FCUSB. And script works also.

 

[D3m0n]

5100 connects in same manner as 5101.

Excellent at least we know the modem and device is fine , and as script now loads you should be able to flash your desired image ,,, but once again , make sure you have backups of your original cfi flash before you do anything

 

[Kris]

So I just load the Haxorware LITE or DIAG version?

 

[D3m0n]

Yes in the hax write load the lite version
