Hi, I have an old Xenon that been working for the past few years. Recently I've done the JTAG hack with the three 330ohms resistors and flashed XeLL.
All went fine, a couple of days ago I flashed the new and wonderful XBReboot 0.05 bin file and I played a little bit with that xbox; no problems at all.
Yesterday, I saw the new XBReboot 8955_1 so I tought I'd give it a try. At the same time I decided to update my JTAG hack from the one with the three 330ohms resistors to the new and "safer" one with the 2 switching diodes (I used 2 1N914) and a jumper. After applying the new JTAG hack and before flashing the new XBReboot I tried booting and everything was OK.
I then flashed the new XBReboot and that's when the RRoD appeared (secondary code 0102). I then flashed back to the initial release of XBRebooter and then to the original nand backup I made. After every flash I got the same RRoD code... I'm beginning to think that the new JTAG hack is not so safe after all. Maybe have fried the GPU or maybe it's a pure coincidence that this Xbox finally died on me...
Thanks for your advices.
