xenon e79 after writing xell

[BGAMods]

As the topic says. Before people start saying bad soldering, remember who I am. I did 5 xenons the other day and 4 were fine but 1 just gives e79 when trying to boot xell. Nand is exploitable, 7371 dash, using diode method. I've even removed the diodes from a working jtag and installed them to rule out bad diodes but still e79. I've rewrite the stock nand and it boots fine.

Johnny had 1 exactly the same the other day. So has anyone else got any ideas? Martin c?

Thanks guys

I've seen you before but can't remember exactly who you are!!!

CB1888 or 1921? Did you flash xell on first 50 blocks or as whole 16mb file?

 

[BGAMods]

1903 and shows as exploitable in xnand healer.

I wrote xell with jtag tool.

It's been a while since I used it but if memory serves me right then try >nandpro usb: -w16 xell.bin 1 50

Any possibility that it's one of those odd xenons that needed the E79 kit which in that case you can solder wires according to that kit?

 

[BGAMods]

I'll grab xell and write it manually with nandpro. If that doesn't work then f**k knows.

I thought the e79 kits were for non xenons? Never even looked into them cause never had e79 till now lol.

 

[manwithoutname]

You must have seen this!

 

[BGAMods]

Bloody hell that's over 12 months ago. I've had a drink since then. Looks like I need one of them kits.

Modtraders sell them so ill grab one tomorrow.

 

[manwithoutname]

If you trace the design or find a better picture you can just make your own.

 

[BGAMods]

now that wouldnt be a good example to set would it now lmao.

ive gotta shoot modtraders tomorrow anyway so ill grab one whilst im there.

 

[Martin C]

Have you checked your J2D2.1 and J2D2.2 resistance values yet matey?

 

[BGAMods]

nope, never had to before lol.

tell me which points to test and ill try it now.

 

[Martin C]

ground your black probe on the board and get resistance readings for the two points. They should be 1.5k each.

 

[BGAMods]

yes mate both 1.5k.

 

[TilVl]

You try the 330OHM method?

 

[BGAMods]

never used resistors in my life, only ever used diodes.

 

[Martin C]

What do you have between J2D2.4 and J2D2.7? A bridge or a resistor?

J2D2.1 and J2D2.2 look ok though.

 

[BGAMods]

simple bridge.

 

[Martin C]

try a 330Ohm resistor....

 

[BGAMods]

ive not got any lmao.

gotta go modtraders tomorrow anyway so im gonna grab an e79 kit and try that and ill order some resistors today off ebay i suppose and see where it gets me. if not then im just gonna update it and be done lol.

 

[BGAMods]

330 Ohm 0.25w Carbon Resistors 1/4w Resistor 330R

is that what i need?

1/2 WATT, CARBON FILM RESISTOR, 330 OHM

or these lol
