have you try hardreseting using hardware button??

To perform a hard-reset, keep the stylus on the reset button and press the lower left (Flag), right (OK) button at the same time. *Note: Hard-resetting the device will cause the device to be reset back to its original default settings and all data will be lost.

yeah. done that. all tried. except for jtag as i hv no idea what it is.

done:
1) soft reset -- no luck
2) hard reset -- no luck
3) remove bat for sometime n then insert back n switch on -- no luck
4) try entering engineer mode -- no luck
5) re-flash -- no luck
6) jtag -- not yet. dunno how. pls teach me.


the only idea left in my head is to sent it to manufacture. but O2 x support stealth anymore. what choice do i hv here? cry.gif



p/s: tomoro i got 2 uni test. why it hv to be at time like this? totally wrong time n atmosphere to spoilt. felt like throwing the stealth kaw². take back then smash till pieces icon_question.gif
