WM6 for HP iPAQ hw6515e

[krrrajah]

Hello bros! Is it possible to install WM6 into 6515? Please advice! Regards, RAJAH

very interested.......:) :) :) :)

technically possible, but if you want it, you do it!

Can you just tell me how can we do it ?

You must find how to load a WM5 ROM filesystem from a 2k3 made bootloader...

Step 1. Analyze the bootloader:
What kind of ROM format can be handled for updating (2003 and WM5 are clearly different, and WM5 ROM formats differs from a device to another)

Step 2. Find a nk.exe:
It's the kernel, it needs to be tooken from a device which is hardware-speaking as close as possible (same processor, same sets of chips, same memory map... Which is possible) from 6515. After some tweaking with initializations (like the 240*240 screen which is particularly rare), you should have a windowed crash. (but it's windows!)
Problem1: No DiskOnChip on the 6515 - harder to find a compatible device - In the HTC Magician forum, someone mentioned the Ubiquio 401 (or Gigabyte GSmart) which has 64MB ROM (and no DiskOnChip?)... But many non-HTC devices are not well described and it's hard to know more about it...

Step 3. Identify all drivers and settings for chipsets
Quite easy since most hardware have been used in many other devices using WM5

Step 4. Build your ROM (using the yet-unknown format)

Step 5. Test and share (use beta testers for massive driver compatibility tests)

Step 6. Declare yourself as a new XDA DEV GURU

PS: Maybe somewhere determine what differs between a/b/c/d/e/f/g/h/i revisions and how to manage it

Has anyone tried flashing a rom dumped from a ipaq 69xx?

[b0ris747]

The problem still the format...

And 69xx has DiskOnChip... I think 69xx drivers could be used in a potential WM5/WM6 65xx... But flashing the ROM as-is would result in a giant error...

The component used to store the ROM in the 69xx is not present in the 65xx... Different low-level technology (CPU/ROM/RAM) means different kernel...

If you want, I have a hw6xxx bootloader (surely a HP mistake, wrong string in the bootoader) which comes from 69xx. And a 69xx ROM updater (I don't remember if it's hpRUU or sable_ruu) contains code to handle (or reject?) 65xx ROM updates.

Things are possible, maybe flashing the 69xx bootloader would permit a new ROM format, maybe would it brick the device?
