DEsire HD Vibrate 4/7 times SOlution ..

[psytr0nic]

not 100% solution but 45% the way

if I'm not wrong , after alot of research and reflexion that is what I concluded .
to finish I think Desire HD vibrating without Power up is HW issues .
mainly due to EMMC . ******* SDIN5C2-8G , MMC/flash Memory IC .

I noticed during Jtag scan sometimes this error '' Flash ID can't be detected'' .
and everytime Flash IC was detected , I had bad Vref Voltage , which not allowed to write dump or repair boot .
Normal Vref is 2.xxV but I had always 1.xxV and with Density:0 ( right is Density:4096MB ) .
when Vibrate only it's not detectible by Pc on USB , detectible via usb if you keept JTag Jig connected .
also reading some topics like that http://forum.xda-developers.com/show...1366795&page=2 have little confirmed my opinon so what is yours ?
better is to let's know your opinion about it . I have one Phone in same condition .
but I cannot work on it now , becoz my hot air ( yaxun 881d ) gun is damaged days ago .
didnt yet found a replacement gun . it will be better if I could try one to confirm my idea .
but once done I will give feedback. Ps : I'm humain like you and maybe I'm wrong so help ... sorry if I duplicated on two forums , I want it be more visible .
