DUDE:eek::eek:

Are you serious????

K750i is a great phone(I have one)... but not that good...

I've got one aswell.. It runs perfectly without Windows Mobile.. Hope it does with tho :rolleyes:

[Sina™]

I have an SE K750i (Black)
SE K750i hardware specs is near to HTC Typhoon.
Also the OS of K750i is: OSE:

Win Mobile ROM upgrade for SE K750i can be the new software revolution.:cool:

[Slayer23]

Omg....

well even if what you are proposing was possible due to driver availibility and compatible hardware, the phone wouldn't be much of a use, video driver will be sure incompatible with any WM build and there would be lack of hardware for input and stuff

If any1 could make that working, i'll eat my shoes :D

[Sina™]

Yes, you're right, but...
The SE K750i input hardware is very similar to HTC Feeler.(Only lack of 1 key).
HTC Feeler is just same like HTC Typhoon.

Is there someway to develop Win Mobile drivers base on those drivers?

[Slayer23]

Well the recompilation 'd be suicidal, but i don't see, how you could be able to decompile the entire GDFSs' and EEPROM for the k750 and extract the necessary drivers for thinks like entire SE based radio stack (GSM and stuff) separatley, so the new WM based stack could be engeneered and implemented as radio stack in rom. The video driver and it's kernell shouldn't be that much of a problem, so if this idea is possible, you could only build a wm2k3 based phoneless rom, without BT and GSM support. And that's just for starters, you'd have to decompile the EEPROM and EROM's to get all the stuff necessary, just to get the entire core of the system working, so the hardware such as CPU could recieve instructions... it's difficult as hell

From my point of view, it would be easier, to compile this stuff for linux, the instructions are more similar to linux, than to WM based core

[Sina™]

IDK...
I prefer Win Mobile instead of Linux.
If there is no way, I prefer Linux instead of OSE.

[Slayer23]

Oh and new finding - i just tried to flash blank rom using Cruiser, and there is no way in hell, you could make something as bootloader for the K750i, so only way, how to get WM to the device is either buying a SE TOOL Box, which costs around 100 Euros, or get some sort of davinciteam.org or wotan.com like server->client based flashers. For instance XS++ is able to read and WRITE the k750i's EEPROM and EROM, but unfortunatley it couldn't write our desired 16/32bit filesystem...


maybe if someone 'd be able to make a virtual bootloader as the phone OS with full internal ROM/RAM read/write capabality - that way we could use normal flashing procedures, perhaps modifing Typhoons or some other similar machines SPL, but still, i don't see how you could push them into the device to behave as we want it to.

Yes, i know you can extract them, but u know, what hexadecimal gibrrish is the GSM driver? i don't think so :D - SE TOOL box is the option - it has sort of predefined links in it's hardware, it basicly simulates the devices RAM/ROM on the run, cuz the devices (SE has no such thing as bootloader or something, the system either runs or it doesn't) can't just "write the stuff on the fly"

[Sina™]

OK...
Just tell me the name of all softwares you need.

[Slayer23]

OK i need someone to make a virtual bootloader / hardware bootloader (SE TOOL Box based) for SE devices, correct me someone, if i'm wrong, but i don't see any other way, how to get entire WM core to SE K750i. The ROM itself wouldn't be a problem, but since there's no SPL, we can't use absolutley different filesystem, than OSE uses

We need high-end SE tech guy.
Did you visit the official OSE website?

[Slayer23]

As a matter of fact, i have a friend working in GS Mobile as SE service guy (it's major HTC and SE devices service center in our country) i'll be seeing him on sunday for a couple of beers, so i'll tell him about our idea, he'll let me borrow their tool box 4 sure and he might even have few other suggestions but since he's a hardware mechanic, i'm sceptic about his knowledge of the software issues - as i said before, the OSE either runs, or it doesen't and what that means for him? Dead phone? -> se tool box -> GDFS, ROM, Filesystem flash -> phone alive, but maybe he knows stuff i don't - we don't talk about software a lot, i personally hate OSE and he hates WM so ... :D (It has gone so far, that when i bought my Touch, he took a deep red (bordeaux for bitches) w910i from his job and showed off all day :D). Maybe some of his coleagues from the HTC division could help us out with the bootloader issue

[Sina™]

Great...
Thanks a hell...;)
Also, the CPU clock of HTC Feeler is 200 MHz, SE K750i is 110 MHz
The SE K750i display is little small, no problem?
What about FM radio & infrared & J2ME?

[Slayer23]

The display size is 220*176 pixels, that is (at least i think) sufficient for rescaling the ui, motorola mpxsomethin220something has kinda same resolution (at least i think (again))
You can forget FM radio and IrDA, J2ME shouldn't be a problem

[Sina™]

Thanks...
I really don't use both FM radio and IrDA.
Yes, K750i display: size: 28 x 35 mm resolution: 176 x 220 pixels, color quality: 18 bit, color support: 262K.

[Sina™]

Since the K750i and W800i are essentially two phones with exactly same hardware specifications, soft modifications are available to convert a K750i to a W800i (software-wise). It will then feature the Walkman feature which is supposed to be available to W series phone only.

& then upgrading to Win Mobile.;)

Enough for Win Mobile ROM upgrade?

Any news...?

Not yet, dunno if i'll get to my PC after the visit in the Pub :)

You can xtract anything from SE K750i with those tools.

Hey :)

So i takled with him and he was rather sceptic about the idea, what he mentioned the most, is the processor speed and RAM Size, he said, that even if we were able to flash the k750i with a WM rom, it would be so damn slow, that it'd be unusable. Anyway, i asked him, to give some of his HTC colleagues my mail, and the moment he writes me, i'll start asking qustions :D

Hi...
I knew it.
It has an ARM9 core CPU clocked at 200MHz, which is likely the
part of a TI OMAP 850 chipset.
After installing WM ROM, we can overclock RAM & CPU.:D
Also, the name of this project is: "WM2SE":D

Did you get that mail from your friend?

[Slayer23]

So we were in pub yesterday, and he said, that there's no way to get WM filesystem to the phone and even if it was, the processor was too slow, but he said that it wouldn't be a problem, to put there 200MHz processor :)

[Sina™]

So, you mean we can't do that?

[hirad_sabaghian]

i think it is not possible, for wm 6.0 we need at least 200mhz but 110mhz?!?! i dont think so...

[Sina™]

I was wrong about CPU info, true info is:

You need the source code for the phone drivers (all of them) you need to compile specific kernel for this phone, you need platform builder and wm6 6.1 sdk, also you need damn good programming skills (or maybe a large team of programmers with damn good skills)

I will explain you why this is inposible, you will never get the source code for the phone drivers :) (ask sony), so there is no way to rewrite the drivers to work in windows mobile

Do you know the name of 1 of platform builders?

[Sina™]

Finally, is this possible with those drivers?:confused:
Please check & test those drivers guys...

I find the solution for drivers:

So, what do you think?

[IkE Blaster]

It's only calibration file, own driver you can't get. It's the same with original k750i language files - you can't extract it.

[Sina™]

From se-nse.net:

Regarding the sourcecodes only SE-people under heavy NDAs have em, you need to reverseengineer them. Everywhere it says "k750 drivers" it's not really drivers, just configs for the devices.

[Sina™]

What this mean?:
Reverse engineer...

[IkE Blaster]

I think they want say that you must totally recode and recompile sourcecodes. Still impossible, forgot on it.:rolleyes:

[Azimuth21]

I don't see how this is at all feasible. The only people that actually have the ability are Sony or Micrsoft themselves, since they have all the resources. You have more hope porting Android to your device, since Android is completely open source, unlike Sony's UIQ and Windows Mobile.

I'd also prefer if you went about this differently, rather than constantly making new posts in this thread for every bit of information that you find. Btw, reverse engineer means that you're fgiven the end product, and you must examine it and take it apart to see how it was put together. We need to reverse engineer so that, once we know how it was put together, we'd know how to put it onto your SE device, which again, I think is impossible.

I hate to burst your bubble, but this clearly can't be done, for a large number of reasons.

Why don't you just buy a real WM phone?
