The word "cold flash" got me curious. Is it flashing fiasco and emmc image together without restart in between each flash or is it even deeeep flashing than this. Coz my N900 was stuck in the 5 blinking dots, I flashed both fiasco and emmc without reboot in between but to no successs. So, I sent it to US coz I bought it from there.

While on the thread, I got I question: I have installed enhanced kernel, swappolube, web OS games, etc etc... but when my device refused to go pass those blinking dots, I flashed like I mentioned above with global firmware (I was already using global firmware from the begining) and sent it to US for repair. Now they are saying my device is out of warranty, does any of these void warranty? (remember I flashed everything before sending it but with global is that the case? coz I know I had couple more days left for the warranty)

Thanks
