Ok, it's tarted 2 days ago, suddenly my new exec screen going to blue (Like PC)??? just blue color (Sometimes white and black stripes) and hung, so I just restart it. But today, is terrible,its happend 6 times. Tonight the worst thing happend, blue screen come again but this time with soft reset, not help at all. Every time I soft reset the splash screen comes, and then that blue screen again. It happend about 5 times, the machine finally start but can't read my sd card and I try to do soft reset but screen goes and never come back. My exec didn't start at all. I tried to release the battery, leave for few minutes and put it back try to start it, nothing happend... now my exec has die.

Anyone please help me and advice please,

Finally it's start but never reach windows screen, the blue screen appears again.

And I remember, the strange thing, my IMEI that I read from device properties is: 355195002465655
But, the IMEI at back body,(Under the battery) : 355195000360361

Why?And what happen?

OK, I've got the same problems as you did. I was so upset with the device that I hit it on my lap (with the battery clip side hitting my lap) and then put the battery back on. Then it turned on! So everytime I have this problem I just hit the battery clip side and it turns on like 70 percent of the time. I just realized the SD card is on that side...hmmm..must be something to do with SD. I'm pretty sure someday it would just stop working at all if I keep doing this.

I don't advise anyone doing this but so far it works for me. I still have problems waking it up though. I really think the mainboard is messed up so I'm trying to get a mainboard, even a broken miniusb mainboard just to test it out. I opened mine up to the last screw and no loose connections noted. So if anyone has a mainboard then can sell me PM me.

If you still have warranty on the device, I advise you to send it in for warranty repair. It seems to only get worst and not better. Goodluck, hopefully we can find a solution for this. If I do get a mainboard. I'll let you know if that fixed it.

Hmm, I've guess it, I think the pprob is mainboard. I'll send it for warranty, (But I bought it in other city not in my own city) So i'll have to send it then on friday this week i'll go to that store to check arround and maybe choose the best product. I'll give the update then.

Anyway someone can give a advice to choose the mainboard?
Thanks in advanced.

bump..we need help..Is it a mainboard or coaxial cable problem? Please advise..

OK, Problem found.. Thanks Corneluis...It is a problem with the voltage control on the mainboard! Anybody has a workaround for this?

[clemsyn]

SOLUTION FOUND!!! At least for my Jasjar. Thanks, cornelius about the info on faulty voltage control which causes the Bulverde CPU to hang and give funny lines and colors to the screen. The solution is to install Pocket Hack Master and disable the Device CPU scaling in settings and set the speed to 312mhz for standby and before you turn it off. Now you can always clock it to 520 when needed but before you turn it off or close the screen make sure the speed is only 312mhz.

This has worked for me for more than 24 hours without any sngle hang.
