Asus A639 briced during upgrade

[c0r3]

Hi ppl,

I just bricked my Asus A639 while trying to upgrade
to WM6. Probably my own fault, the SD was FAT32
rather then FAT16 and I noticed too late.

Also, I was stupid enough not to create a backup
of the WM5 first so I'm really stuck here.

I have been reading the forums on this but many topics
are mixed up ; they discuss migrating to another language
mixed up with rescueing the device.

I am not interested in switching language. I have read
that it is possible to force a WM5 image onto the device
but there are two issues ;

1. I don't fully understand how to do it
2. I don't have a WM5 image

So I guess I have two questions ...

1. Can anyone provide me a Dutch Asus A639 WM5 backup
2. Can anyone tell me how to get it onto the device.

Tnx,
c0r3

Got it fixed. Many tnx goes to cmonex !

There was a post some time ago which described how to recover from
a crashed upgrade ....

I started of by downloading the official WM6 update from the Asus
site. I renamed the Update.img to A639_K733.DIO and tried to get it
onto the device. Although it did load, the PDA still wouldn't get past
the Asus welcome screen.

It appears the .img file from the update package contains too much
for this to work.


find MSFLSH50 signature (search for string in a proper hexeditor!!) in the file, then go back 512 bytes and cut everything until then.
so the remaining file will have the MSFLSH signature at offset 0x200 (i.e. 512).



So I tried but could not find the "MSFLSH50" string in the .img file. Tried
several different hex editors, no luck.


ok, it is possible it is a XOR'd file, some ASUS updates are like that.


Once I got the correct file from cmonex ;

1. Formatted SD FAT16
2. Rename cmonex's file to A639_K733.DIO
3. Copied file onto the SD
4. Inserted SD into PDA
5. On PDA : press+hold power+enter+reset
6. PDA enters bootloader mode and copies the file into the ROM
7. Press reset on PDA and all boots just fine although it takes a while before
it passes the Asus welcome screen. This is only the first time after the
download however. Reboots after then go as they should normally go.

The hard part in this sequence seems to be to find a decent ROM file.
Once you have a file that contains the MSFLSH50 signature it pretty
straight forward.

as someone sent this link to this thread to me in PM just now I thought I'd clarify some details..


a sample english .DIO is available from my server, but link is not public - you can PM me


otherwise, to obtain a .DIO, just make a backup of your ROM with pdocread while PDA is still working. if help is needed with that, please post the output of the command "pdocread -l"

Hello there,

I have exactly the same problem as described here. I also tried a rename of the
Update.img to A639_K733.DIO which did load and was written in the ROM but the device still "hangs" at the blue "welcome" screen.

Would it be possible to obtain the "correct" .DIO from one of you guys? That would help me a lot! Thanks already in advance!

My system is originally Dutch and I would like to stick with it, so I would need a Dutch .DIO, but since I have a backup of my old system made with SpriteBackup, I guess (or better hope), also an English .DIO will do.

Again, thanks in Advance,
Andreas
