Hello !

I'm having really annoying problems on my 360 slim .

First, after I got the box, I updated it and then flashed it to 1.90. Then, my brother accidentally updated the dash to a newer version. So now I'm stuck with the 0272 FW.

The problem is, with the 0272 I simly can't get it to vendor mode to flash it to 1.91, and also the flash is gone. With stock, there were no problems, worked like a charm.

So my question is, do I need to get a proffesional to do this ?

NOTE: I DO NOT have any proffesional hardware to do this, I power my drive with the box, don't judge me, for I do not care for LIVE. And don't tell me that I'm power cycling too slow, belive me, I tried. :facepalm:

9504/0272 drives are locked with the new 13599 update. You will have to unlock it via SPUTNIK360 if you have a MXIC flashchip, the Kamikaze hack if you have a Winbond flashchip or use T-X's Unlocked PCB.
