[laleyandasvivenporsiempre]

After I mistakelt upgrade my s200 with a Kjam rom, the device will not turn on again, now I need to boot from the sd card has anyone an OS backup which work on Sd card?

I ll try to alive the device from sd card but I dont know how I copy the os to the sd card.

Do you have the bootloader alive?

thanks for your help, no I could only reach to Bootscreen when the wall charger plugged, but naturally I could not update the rom from the charger, so I think the only solution is using a backup image from the sd card.

AFAIK, it means that your battery is empty. Try to charge the battery with any working S200/100/110/9100 and you will be able to run the bootloader, then you will restore the device. Correct me, if I wrong.

the problem is not about the charger or battery, although the battery 100% it still cant be opened the problem is after load the Kjam ROM, the device reject to open, it could onyl turn on if the wall charger is pluged however I could plug the USB data cable at the same time. I send it to the service center hope they could recover the device...

This behaviour is typicel for a device with both broken image and discharged battery. The battery WAS at 100%, but the Prophet does not charge it if has no working OS, so the batery was drained until you tryed to reanimate the device. Ensure that the pattery is full with other, working device.

Walker;

I charge the battery with an other prophet I ll wait untill the light become green and battery is 100% then after when I tried with the boken prophet it did not reanimate the device. it is very interesting to see that wizard could work with prohet's rom but not vice versa

Let me relate my experiences; exactly the same problem.

Update KJAM rom on DOPOD 818Pro ... Damn phone could not power on at all, at most on bootloader, plugin USB cable --> no USB word displayed at bottom.
Try to flash any RUU also no go ...

ON battery, could not power up at all, only plug in wall charger then managed to get to bootloader ... so all was lost.

Send to EBAY (where i bought from) and they flash the bloody Dopod 830 ROM..
During collection, plugin my own battery, same cannot power up... evidently the flash to Kjam killed my battery too !

The good thing was that with the 830 rom, my IPL became 2.16 (from 1.00).
So i reflashed to Dopod latest 2.15 ROM ok... further flash to AKU 2.3 hacked ROM also no problem.

SO, ultimately the cause was a killed battery from the ROM update.
Use a meter to measure contact pt 1 & 2 from top edge of battery, (supposed to be min 4.7V) I believe it's 0V or totally shorted out.

This battery cannot power on the phone, but still can be used as spare battery by power up with wall charger first, the battery still has it's 3.7V available to sustain operation.

So u can go buy a new battery and Flash to the correct ROM now.
Good Luck

to buyaoxiao;

Thanks for your comments but;

I think there is something more serious than the battery; I have two prophets, and I also try with the other's battery and still nothing happened, more than that, both of the batteries work with the non-broken prophet.

[buyaoxiao]

Hmm.. that may be true also.

I cannot really conclude as i was lucky the ebay shop i bought from agree to flash my S200.. i believed they had some trouble too as it took them a week to get it to Dopod 830 rom ... when normally they say 1 day will do. They refused to go into specifics though... (afraid that i demand for 1-1 exchange)

I have had the same problem, so that's why I decide to sent to dealer to try to fix it. Now I'm expect to have a call to pick it up. Hope they can improve my prophet to the new chip G4.

I tryed several times, hours to fix it, but no way. Sorry I can not tell you something good.

[laleyandasvivenporsiempre]

I am sure that there should be a way to fix those devices Jtag should not be the only way( if it really works) it is meaningless to loose a device only because of a wrong rom update:(
