Develop Rom For CPU With Same Instruction Set - Upgrading, Modifying and Unlocking

Hello evrybody!
i wanted to know if is it possible to develop a rom from a rom for OMAP 850 Cpu (here) for OMAP 1710 (here).
They both got the same Instruction Set: ARMv5TEJ.
Another thing that i can't understand is how wm5 works.
just do i need to change drivers from a similar device to get a good rom?

a rom is the core plus 100% correct drivers and 100% correct settings
or it will never boot
same cpu don't mean a thing
apart from features embedded in the cpu
such as qualcomm got wifi,gps.... on cpu
apart from that they're all arm and is code compatible as in
use the same cpu instructionset

So... if i find correct drivers and good settings can i build a rom?
Can i use wm2003 drivers and settings?

yes device makers get platform builder from ms which makes it possible
and no you can't use wm2003se or earlier drivers or settings

And if i take driver for a device (wifi card) From another phone with wm5 and the same wifi card? Are they good?

How can I dump the rom?

Hello everyone, I'm from China and I got a new CDMA 1X Pocket PC Phone which runs on WM 6.0. But I don't know the hardware of this device. It's an engineering sample. What I know is that this device use Intel PXA 27X CPU.
In this case, how can I dump the rom of this device?
If not, is it useful or helpful for anyone who doing the research of CDMA device in order to make WM 5.0 runs on Harrier(CU928 in China)?

Maybe a stupid question...

Why isn't it possible to install a eg. Hermes WM6 ROM on a P3600?
Sorry for this question..

No, and if you do this you send your P3600 directly to the trash!
Hi,
Windows Mobile - as Windows XP - relies on drivers. Since the devices' ressources are a lot smaller, the Plug'n play is limited to real peripherals. Concerning the core drivers like processor driver, graphics driver, keyboard/screen-driver and so on, Windows Mobile relies on the OEM to preconfigure the OS to load the correct drivers for your device.
Furthermore, HTC has changed the internal format of the ROM-file over the different generations of devices. The OS occupies only a part of your devices' rom, and it needs to be in the same format as the rest of the components.
However, it is possible to transplant a large part of on devices' rom into another device. The rom is structured into an xip, an oem and a sys-part. The xip and the oem-part are device-dependent, while the sys-part is portable.
Have fun!
try it ......please don't
you will just make a nice looking brick

Upgrading Hitach g1000 from sprint

Is it possible to flash the sprint hitachi g100 (sh-g1000) to linux or a later version of windows mobile?
i dont think so, unless you can port the xip and cid unlock it yourself. or find a forum for the device itself. this forum is for htc phones, and as its made by hitachi, i dont think it can be done here
Rory
from what i recall then that device dont even have a flash based rom but a hardcoded one so it can never get any rom upgrade at all official or otherwise

It has a PXA cpu, and an ATI W3200 video+USB+SDIO.
AFAIK nobody tried to port linux to this device, though it should be doable.
You may run haret.exe on it, and post the haretlog.txt here.

Google Android running on the hermes

On a whim I was browsing new posts on the xda forums. it seems that the guys over on the kaiser rom forum have gotten google android to boot on the kaiser. I thought hmmm... the hermes is like the kaiser, lets give it a try. So I installed the HaRET loader, got the 24mb cab file, and the latest zImage and installed it. Followed the instructions and got the hermes booting linux. I thought hey this is easy! next step, ditch WM and go with tux only. Whoops! not so fast. seems that linux won't load past the 'jump to kernel' part. I urge someone else to try this! You really need to install the cab from your sd card, and it eats up all your ram but hey its something new.
btw, use your hermes kb in the complete dark.. your eyes color shift and the buttons take on a red hue. weird. also the forum looks like crap on my hermes. isn't that ironic?

Booting Google Android
1. Goto: Start -> Programs -> Accessories -> Android.
2. Pres: Listen for network connection. Meanwhile also press run (Doing this makes Android boot most of the time).
3. Google Android is now booting or you're Kaise freezes.
4. Have fun or Soft-Reset!
If Android Is Not Booting?!?!? (Even after 20 tries). Run ClearTemp... http://www.4shared.com/file/50007273...ClearTemp.html Then Boot again!!
Menu
At this moment there is no back key mapped. So the only way to get out of the menu is by soft-reset. Ppl are working on this issue, tyring to map de back key.
FREEZES
You are probably using the original zImage of SH4Y'S CAB. Use one of the latest zImages...

All I did was download the files, install the cab, and run HaRET and try to boot. I get the "booting linux" screen and then the linux "boot list" but then it hangs. I'll post a few pictures. My rom doesn't have a screenshot grabber, plus I don't think you can get a screenshot when you aren't even running WM?
Click Here for a way to create a fresh kernel (zImage.bin) which is possibly the fix for the hermes.
Click Here for images of Android running on a TyTN II.
EDIT: Ok so I know why its hanging on the loader... The kernel is compiled for the wrong processor. The vogue uses a different processor than the hermes. Working on this.

The phone power, reset and AT CMD serial port settings are missing
in the hh.org CVS kernel. It's not very difficult to do, but nobody
has done it so far.
Interesting...Here's the original hermes discussion thread on linux (over 100 posts):
http://forum.xda-developers.com/showthread.php?t=273579&page=5&highlight=Android
Looks very cool, but I guess a long way before it will work with all hardware like, radio, wifi, bt etc?
Perhaps I hang on to my Hermes for a while to run Android!

Honestly I was thinking of jumping ships to either an iphone or a clone but I think I may wait a year and see what happens to the hermes with android. It would be nice to get it and play with it for a while so in a year I will know exactly what I want to buy and the market will have settled down a little bit.
I have compiled new zImage and HaRET. In default.txt I have lines:
Code:
set kernel zImage
set initrd initrd-android
set cmdline "root=/dev/ram0"
boot
I loaded newest initrd-android from http://it029000.massey.ac.nz/vogue/
With these settings Hermes boots and it even set system clock (2028-07-05 10:40:21 ) but hangs after that, HaRet says in last line: "Freeing init memory 88k" and thats it. The initrd-android is not for Hermes and I don`t know how to make new one for Hermes. Or is this memory freeing thing more about problems with zImage?
Did you compiled it with the HTC HERMES flag?
Maybe you can upload the zimage/Harret to your post? sow more people can play with it... would be cool.
I also tried to compile a new zimage...it compiled, but it stucked at booting it with Harret. "Load kernel image" (or something like that)
Here it is. I used branch "work" and from there you can found htchermes_defconfig.
Thx..
I have the same issue as you have
But it dont give any error messages...and some key's on the keyboard(buttons) still give some respons on the screen...
And when you boot it with the usb connector with it, it says something more about that conexxion..

I can't even run haret.exe (the android entry in Accessories). It says it's not a valid Pocket PC application. Any ideas??

Android Running on HTC Hermes
Hi guys, I've two days trying to run android on my htc herm100 but I can't do it. Someome may help me to compile a new kernel whit the features of my htc?? The only thing that i did was run linux on my device.
lol, why are people still messing with this?
It is NEVER going to run on the Hermes.

dude...
It's not a simple matter or using the right version of this or that, or configuring it a certain way.
Haret will never run on the Hermes, making it impossible to ever run Android.
Hermes hardware is too old and too slow to run Andriod.
Haret can't even access the sd-card. Even if some how, some one re coded haret with the proper driver (which will not happen), there are still 100 other hurdles to over-come. They would have to get the graphics acceleration working with the ATI chip, Wifi drivers, Bluetooth drivers, etc... not to mention the actual instructions set of Andriod won't even run on the processor in the Hermes.
It will never run on the Hermes.
If you want to run Andriod, you should buy a device that supports it. Hermes will never be one of them.

is this some kind of a subliminal reverse-psychology message designed to challenge some dormant genius out there to waste a coupla month of his life to prove u wrong for the benefit of everyone else here at xda-dev?! ... if so, keep it up.. I hope such genius(es) picks up this post and gets all fired up and go "HOW DARE HE! I'LL SHOW HIM"... then.. *tick...tick...tick*.....*ping!*...
oh and while ur at it... Android will NEVER run on the Trinity either!!!
Funny thing....
Hi there,
it's getting funny how many poeple out there discuss the android on hermes issue.
Basically it's not the speed of MPU or a memory issue on hermes platform.
I'm quite sure that android would do it quite well on a machine with 400MHz and 64MB of RAM .
Android in fact has another important basic requirement:
It will require at least Xscale CPU or SoC with ARM926 or higher to run properly.
All binaries in the root filesystem of android are compiled to run on an ARM platform with at least V5 instruction set.
Some older devices use some kind of PXA SoC's or OMAP SoC's which talk V5.
That's why android may be ported to run on those .
Hermes uses ARM920T SoC with ARMv4 instruction set, so a standard Android root image will not work.
That's the reason why it will be very evil thing to make it ever run on the hermes platfrom.
Someone has to fix all parts of the source code that requires V5 instructions and do a complete compile of all binaries suitable for V4 command set.
Of course to do all this a nearly complete linux subset is needed too.
As already mentioned the kernel for hermes is far away from some kind of usability .
Nevertheless, it would be very cool to get any kind of linux run nicely on hermes. Please help out with reverse engineering and writing drivers to make this come true. Perhaps also other dreams may become reality this way
Best regards,
scholbert

MS20 ROM Upgrade

There any rom compatible with LG MS20(a brazillian version of KS20 without 3G, WIFI and front camera) the others specifications like processor is the same Qualcomm MSM7200 400Mhz, 128MB RAM, 256MB ROM, the frequency is the same too, But i don't know if a can install the KS20 ROM, if i try may i can brick my phone?Or there a way to i extract my rom to you modify?
You can use any rom from KS20, it's the same phone, with the 'same' hardware.
PS: processor is not the same one. MS20/MS25 use MSM7200 250mhz, and KS20 use the same MSM7200 but its 400mhz.
But, if don't work, i can go back and reflash the original rom?
Sorry for the double post
Ok, i found the engineer menu, the ROM Version is V10a, and i wanna try upgrade, make a tutorial(if possible in portuguese) to upgrade the phone without lost the nv2, imei number, i am newbie on flashing wm phones, so please make a detailed tutorial to all people of Brazil. And the KS20 WM6.5 rom works perfectly on MS20?
Sorry, but anyone can do a tutorial to install the windows mobile 6.5 in the MS20/KS20.
