Default HELP!boot loader doomed on my dopod 818pro

Guys, I'm frustrated now. I've refreshed the ROM of my G4 version of Dopod 818pro (2.15.0001 or something I just can't remember). Unfortunately it fails and I cannot even turn the power on. My WinCE colleague told me that the Boot Loader was damaged. I am now seeking for some place to re-program the chip and hope if someone can provide me boot loader program. I really appreciate your guys help!!!

Are your Bootloader Realy damage? You mean you cant enter it? Or you havent Power to start your Device?

SD Flashing doesnt work without Bootloader!!

JTAG Flashing (hardware nearest Flashing!!) isnt developed for G4 Plattform. (i think so ... look in the Wizard board ... they talk about JTAG flashing and Wizard G4 must simulare like Prophet G4!!)

the bootloader really damaged, I cannot enter the three stripe screen by holding CAM, PWR button and hit reset hole. Do you mean that I even cannot use JTag to burn the chip???

I do have two fully charged batteries. But it should not be a problem of battery, I tried to connect it to charger but it gives no response, no LED

Using JTAG to revive a wizard is either a myth, or an undiscovered secret. If you cant get into bootloader, your chances of reviving your device are slim.

JTAG isnt a secret ... its more like ... hardware knowlage. If you know what IC is your ROM. You can found over the IC Spec the right Pins for JTAG Programming. If i can get a G4 S200, i can try my best.

yes, I know that using Jtag to rewrite boot loader is complex, but it seems like it's my last chance. NetrunnerAT I really appreciate your help but I'm in Shanghai, China so I have to find someone locally who can help me with that. Wish me good luck and I'll keep you guys updated about the result

guys, I finally found a place to revive my prophet. However, they don't know how to jtag it either, neither do they have a programer to rewrite the chip because they say the programer is very very very expensive. They just changed the old chip with one which has correct ROM and now my G4 Prophet turns to a G3 one...anyway, I can use it now.

Thx!
