O2 XDA Exec Won't Power On after Unccessfull ROM Upgrade

[dineshkumaar]

Hi...

I was trying to Upgrade my O2 XDA Exec Rom with Windows Mobile 6.5 by explode. The process went successfully till 99% and after that it ended up with Error. Then I unplugged my pda from the pc and tried to restart the device. I was surprised that the device did not respond to any of the following

Soft Reset
Hard Rest
Boot Loader mode Start (Bulb + Power + Reset)

It is totally blank screen whatever you do.

When I connected the device to the pc with usb cable, a Red Light is shown for 2 seconds and then goes off and a message comes up on the pc that "USB DEVICE NOT RECOGNIZED".

Then I tried to Remove battery from the device for a whole night and the next day morning i did all the above procedures again to get no results.

Kindly Help me out

Thanks

if it's not recognized, remove the SIM card, the SD card, and on the PC open activesync and disable usb connections. for more info open this link

you have to find another rom and try to flash it to your PDA.

ARE YOU RUNNING windows XP on your PC?

[dineshkumaar]

Yes ! I have Windows XP SP2 and Active Sync Version 4.5.0 (Build 5096)
Thanks

have you tried to upgrade another ROM, and if you did, is your PDA now working?

[dineshkumaar]

I cannot update my rom as my pc cannot recognize my device. is there any other way to update rom?

Try to reflash with another ROM

Hope it helped
And don´t forget to vote!

[dineshkumaar]

I had already done those steps to get no results.
its my badluck.

[timmymarsh]

If you cannot get into bootloader and you have done the steps above, then you cannot flash to another rom.......it would seem you now have a paperweight im afraid:o

[dineshkumaar]

I am still not able to revive my device. I know that it is just due to corrupt bootloader but don't know how to repair it.

If anybody ever has solution for this... kindly let me know.

Have you tested mtty?
I would recommend to PM a chef on Universal forum

Good luck,

[dineshkumaar]

Mtty is not detecting my device
it says can't open usb port

[dineshkumaar]

One More thing I have noted is that when I keep the device connected with the pc, at a certain interval of about 10-15 mintues my device's Led shows RED Light for few seconds and then turns off followed by the the "USB device not recognized" on my pc.

I hope this can be used as a hint towards reviving my device.

Regards

[timmymarsh]

have you followed orbs advise above and pm a chef on that section, they maybe able to help. From my knowledge (limited on that device) i ddont think there is any recovery proceedure that you have not tried. Have u downloaded offical wm5 rom and tried it. I know and appreciate that it will probably not work due to corrupt bootloader, but what else is there to do??

To understand more, what did you do PRIOR to trying to flash to 6.5.

Did you hardspl correctly? Had you already flashed to another rom and just felt like flashing to another new rom?? Give us more detail.

[dineshkumaar]

Thanks for your reply

I dont know how to PM Chef.

I had used 3 other Rom versions of WM6.1 on my device. They ran very much fine on my device. But When i found WM6.5 xplode, I wished to try that too. But the rom update procedure went successfully till 99% and after that it showed an error that upgrade was not successfull. I pulled out the device and tried to restart if by all methods but I wasnt able to power on at all.

Thanks
Regards

ok, goto the thread that you got the rom off, click the chefs name and you will get a menu there to send pm, do it, he might have seen a similar problem or know how to correct bootloader.

good luck

Is bricked

my bro has bricked an Universal and the same led turns red no power off no bootloar no power it means the flash chip is dead!

Sorry to heard that.

He waits too long for the upgrade it tooks at least 40 minutes
then ERROR... but you know... the batt was died in middle process ( th batt was fucked up, it say full charged but no! it was on 60 or 50%) then the stupid thing is make a hardreset.. i told him dont hR your device... justa simple reste and reinit the process... and huh! its bricked.

if you are interested on sell your parts
maybe my bro want some parts. :cool:

my advice(similar to other people):
1. Charge your batery somehow (in other device or anything else)
2. put your devce in bootloader mode and connect it to pc - it wll be detected like microsoft usb sync
3. use mtty try difrend versions becuse sometimes 1.42 does not detect it properly - read here for what to do with mtty (http://wiki.xda-developers.com/index.php?pagename=Uni_Stuck_Bootloader)

IMO this may be battery problem or nand chip problem - in both cases it is hardware fail

[dineshkumaar]

Thanks for your suggesstions but my Battery is fully charged. Even it doesnt show the charging light, I keep on charging the device and in fact the battery is also geting heated normally. I checked the battery with multimeter and it shows the value of 3.78. It means the device is charging but not showing the chargin led.

further I dont have any other such device to charge my battery with. I couldn't get it from shops too coz it is a rare piece in india.

any further sugessions please..
