@ Cap, sorry for more OT, but I do believe you understanding my inclination to reply to the above, so if you don't mind, so i'll just hide it :angel:

@computerslayer, yes, i have been made aware of those posts you mentioned, they are very elaborate and true, so I stand corrected, but FYI, this is the first device I intentionally go from S-OFF to S-ON

I can't say it was one of the nicer flashes, (especially when the cable get's removed by accident), and I wouldn't recommend it to anyone either, but the fact remains, that my bootloader is UNLOCKED, I have set S-ON (dont even mention how that sounds coming from me) ;)

so in conclusion:

UNLOCKED

S-ON

was able to fastboot flash ruu.zip (for a non-Developer edition) without [too many] issues

though I did come across:

(bootloader) ERR [SD_UPDATE_ERR] Main version NOT ALLOWED
(bootloader) ERR [SD_UPDATE_ERR] sddownload failed: 19
(bootloader) ERR Update zip file failed.

which [MENTION=1162986]Captain_Throwback[/MENTION] might find "interesting" ;)

will test that part some other time, since I'm S-On again.... yay :p

PS: yes, the phone boots fine :cool:
