hp rw6828 wm6 (odd conditions) -> wm5

[elus]

Hi guys,

Hi,
I'm a hp rw6828 user and is very much enthusiast to try out those wm6 roms made by those experts. However, i did a mistake while trying to flash.

I tried flashing with a rom from wantat but i forgotten to delete the EBOOT.nb0 before i clicked "upgrade". Then the program stopped at 6% for a long time and didnt move. I disconnect the cables and tried to turn the device on.

THe device can go into the wm6 and the start button can be use but the screen is "moved" to the right side and other function is not working.

After that, i did a hard reset and the the os seem to work like normal. However, when i tried to go into bootloader mode by pressing both "_" and soft reset. That didnt work. I tried another way by taking out the batt, leave it for a 10mins, press both "_" and soft reset, put in batt, release soft reset then "_" keys. That didn't work either.

But, just lately, i've tried taking out batt, holding the camera key and softreset, place back batt, release soft reset n camera button. This method works and i get what it seems to be an atom bootloader?

i get a black background with "MN1 Bootloader Mar 29 2006 13;52;14 copyright..... 1) debug module through UART 2) jump to DM Enter your selection.

I've searched the forums and found few ways to downgrade back to wm5 but those aren't the same conditions with what im facing. Can someone recommend how can i downgrade back to wm5 with the conditions that im facing? All you help is much appreciated. THank you.

You are lucky , at lease your device now become atom. My was totally cannot on power and just vibrate. Till I have to sent it back to HP SC and change the main board . Can you understand chinese , if yes than I have a solution you may try . Else you have to wait . I just download a program and doing some testing , the program is in chinese language .

Thx for you reply. I guess u can say that. I'm from msia but cant read chinese.
Is it possible to solve the problem by sending back to hp using warranty claim? I think i still have warranty left but its ending very soon. One more week i think.

I don't think you still can claim under warranty unless you can make your phone total can't on and access to windows mobile. Last time I sent it back they charge me RM 385 to change the main board . I did talk to their technical personal , it seen like they don't know what is bootloader and flash it back to original rom . What they do was just change the main board with preloaded program .

Good luck

If you think that you can claim you warranty , than you just go a head . If not , may be you can access my thread "HP6828 WM6" , download any one of the rom that I post , follow the instruction accept downgrade bootloader . Enter your phone in bootloader mode . If you can start the process , than it will flash a new hp bootloader into your phone .

Against . Good luck

Cheers
I'm from malaysia also.
