WP8 custom roms for older devices - Windows Phone 8 Q&A, Help & Troubleshooting

Hello ,
Does anyone know that Is it possible to cook WP8 roms for older devices? I know what Microsoft said about it but maybe some people can o it ...
I've did some digging about it , there are some points to consider :
In hardware view :
* compatibility of the Qualcomm Snapdragon S1 (First Generation) and S4 (Forth Generation)
The S1 Chipsets are 65 nm and the S4's are 29 nm
Dual core architecture of S4
There are some newer technologies like LTE that older chipsets doesn't support...
* Driver compatibility for OS with old hardwares...
In software view:
* hacking the OS and reaching source code for cook
WP8 have bit-locker encryption (Mobile Version) and it's so hard to break ...
if anyone know anything else about it or right now he/she is jailbreaking the OS please let us know ... thanks

I highly doubt it. The operating system is built to run on only that chip set. That's why most wp7 phones had the same CPUs and why most wp8 phones have very similar CPUs. I don't think Microsoft is lying to us about this one.

I really hope so. I don't feel like upgrading my HTC Titan, the hardware is fine but WP 7.5/7.8 is garbage.

Non so se potrebbe servire a qualcosa, ma vi allego uno screenshot che ho fatto con il mio lumia 620 quando, scaricando HERE drive+ , durante l'installazione mi è uscito questo codice per pochi secondi. :fingers-crossed:

To address the actual image... that's a weird glitch, but not a big deal. We already know where apps get installed to (you can actually query an app's install path from within the app).

nothing is impossible, it just require hard work. if d wp8 official rom can be compressed to a size to be able to load on old devices, den it can work. like i said it requires hard work.

I can post with a fair amount of certainty that those of us who actually do anything in WP8, has no interest in doing so.
I'd go bother WP7 devs, because they have the old WP7 hardware and might have a slight interest in putting WP8. Those that did set it aside long ago due to the difficulty of booting it. Now that we have figured out the ROMs, there might be a way to do it, but I'm not sure how it would interface with the cellular settings, and the interest has faded even further.
Most of the WP8 people who post here are Android converts or just new to the platform in general, but that's me making generalizations of something that could be completely different.
WP8 supports quad-cores and apps made for it would cry on devices with 2010 specs, so....
It might happen, but I certainly have no interest in using it on my HTC Trophy.

Windows Mobile 7

Does anyone know when will MS launch this version of OS ? Really would like to test on it or see how does it looks like..
If I understood it right, is the OS still under development. So you will probably not see much from it untill next year.. I guess
jea in half 2010 is release... win7 mobile vs iphone
it will be f**king good
Microsoft will start sending builds to OEMs to begin testing in Q1 2010. WM7 will be released in Q3 2010. I expect to see builds out sometime in Q1....however, I'm not too sure these builds will run on anything presently out besides the HTC HD2 because the CE kernel would have been recompiled for ARMv7 cores.
and that will be great. what is coming out from iphone next year to fightfwith android 2.0 and winmo7 ... and ppl will start porting their hd2 to android 2.0 and then to winmo7... lol
In the first place X1 probably can't support WM7
doesnt the 6.5.1 need to be released first?

It's a very technical requirement.
The Windows CE kernel, very integral part of Windows Mobile, is being compiled for ARMv7 for Windows Mobile 7 (thought to be based on CE6.0 or CE7.0). Currently Windows Mobile 6/6.1/6.5, the CE (CE 5.X) kernel is compiled for ARMv6 which runs on many chipsets today (Qualcomm 720X for example).
ARMv7 architectures (ie. Snapdragon, Cortex A8, NVIDIA Tegra) are backwards compatible with ARMv6 which is why the HTC Touch HD2 (Snapdragon) can run Windows Mobile 6.5. However, ARMv6 architectures (X1, TP1/2, Touch HD, etc) are not compatible with ARMv7 code (missing/different instructions).
So unless a very smart cook can somehow recompile code (need the source code) or combine different parts, there will be no WM7 for any current windows mobile device besides the HTC HD2.
x1 didn't get wm6.5 officially if it will get wm7 which will prob not be out until a year from now don't expect it to come from official sources.....
Min requirements for WM7 is 1Ghz CPU (actually because of the instruction set), but also G-sensor and compass. HD2 maybe. Xperia no way.
Well you say processors like Tegre will be able to run WM 7, but i checken and Tegra is still ARM v6...
Anybody has any real source saying Wm 7 will be only for ARMv7?
As for G-semsor multitouch and sucks, that is all softwere, you can turn this things off, so apat from procesor, nothing else matters for WM7 to run X1, onl ARM v6 code is needed, all else can be done by cooking.

Hello,
I am brisschris.I am new to this site,but I’ve enjoyed posting in your forums.Microsoft confirmed that it is planning for Windows 7 to hit retail shelves and start showing up on new PCs on October 22.To reach that milestone, Microsoft plans to wrap up development of the operating system by the middle or end of next month.The tech guarantee program is not beginning immediately, but Microsoft did raise the possibility it will offer some sort of lower-cost upgrade to those who are already using Windows Vista.it is "Depending on when we do it there will be the associated accounting for it".
Thank you very much and Stay connected with me.

Uh.... we're talking about Windows Mobile 7, not Windows 7.
Come on Guys!
Please dont speculate about things there was lightyears ahead. Wait untill the time will come. We dont have seen WinMo 6.5 official on X1 yet, therefore we think about other things, which atm is morge important.
with best reguards.
sorry for my poor english
Well lightyears ahead you say, but i am certain i will have WM 7 on Xperia in abaut 3 months XDA does miracles
Certainly the most x1 user will it and im sure that the devs find a way to port it on x1. But except a few screenshots no specification of WinMo 7 was published. Therefore hope that the x1 get an official 6.5 Update. I think, this will reveal the way to WM7.

WP7 on X1

Hey all has anyone been secretly working on the wp7 rom for the X1? if so lets start a thread for it
i don't think its been leaked yet, has it?
Well I dont know if anybody is working but I trying to make this theme
http://forum.xda-developers.com/showthread.php?t=633755
I love to have WP7 on SEX1 (if it is possible)
I guess hardware requirements wont let you to function smoothly but chefs here can save us with a barebone edition of WP7
Cheers
i hate to break it to u guys, but we don have a proper OEMXip and drivers from wm6.5 which is the same CE version as 6.1
how do u expect a XIP + oemdriver for wm7 when its completely different driver set + newer version of CE.
n lets no forget the touch capacity screen requirement of wm7
so unless MS decides so make it backward compatible to older device, i just don see it. and knowing MS i don think they will. coz they cant sell just an OS at retail. it comes with a device. so if the old device can run 7, it will mean less sell of newer products will be sold and no company would want that.

Yes, that's correct.
But can't you guys, extract WM6.5 drivers out of the xperia X2? The hardware is almost 95% the same as our beloved X1 D), right?
sadly we wont be getting windows phone 7
but there are rumors that microsoft is making a sucessor to the 6.5.X line. I really do hope so! CE is soooooo old! and the new 6.X better not be CE.

Now i know that there is a good chance the screens were added post recording and are all fake... but lets all just keep our hopes high and fingers crossed
i'm not very sure about drivers. We have seen that htc devices are quite similar about hardware so maybe possible, as we are already doing with wm 6.5, to use drivers of other devices.
cant we update the CE..

If you mean update the CE to CE7 then No, as stated above it is pointless to even be discussing this right now since we don't even have the proper hardware/drivers to even run WP7 properly and the beta isn't even out yet, your just going to have to wait for 6.6.
If you guys want WP7 so badly try upgrading to new hardware.

Yeah, but like if they build an htc with such low-end hardware like the xperia for such a high-end os like windows phone 7, no way thats gonna happen. No way they are gonna beat iPhone then.

We are not using drivers from other phones. Atleast not the whole OEM shizzle. Drivers(except some video drivers etc) are device specific and can't be used on other devices
min specs for WP7 is quite high... i read snapdragon +1Ghz CPU would be required...
credit to msoft for raising the bar (ensuring user experience will be similar all round)
sadly this means that our qualcomm 528mhz processor + ati graphics might not cut it...
While this does make wp7 look nice with the high specs, it would also make the phones more expensive. Though, snapdragon should be cheaper by then.
WP7-lite for us 528mhz people!

[Q] WP7?

Hey.
I noticed, that the Omnia 7's and the SGS's specs are just the same, and I wonder if it could be possible to port WP7 to SGS. What do you think? I'm not a programmer, so I can't do anything for it, just aksing.
Android = Open source, developper friendy os
Widnows = Closed source, licensed used.
altouch might be doable, since phone with WM6 got 6.5 (HTC Vogue or the likes), I assume if all the drivers are available it would be.
BTW: Question already asked and answered many time, you can always use the "search" fonction
A custom bootloader to start up WP7 would need to be created. You can start Android on Windows Mobile hardware because of Haret.
It also looks like Microsoft standardized the 1GHz Qualcomm QSD8250 Snapdragon chips for all WP7 hardware at the moment (yes, even Samsung's devices, you'd think they'd want to use their own Hummingbird) in order to reduce fragmentation. The S5PC110 in our Galaxy S's uses completely different hardware drivers and compiling them to be compatible with WP7 would probably be quite an effort or impossible.
If at at all possible development would begin on QSD8250 handsets like the HTC Nexus One or Desire. Maybe we'll see more developments as WP7 begins trickling out but I have my doubts.

Windows 8 on the Touchpad?

Hey Guys!!!
I've read threads here and there about porting Windows 8 into the Touchpad, but I want to have as many answers as possible in one single thread.
Will it be possible in the future?
What obstacles will the devs find porting it?
I know this website is big in Android development but I want to see different options
licensing
unless microsoft starts selling windows 8 licences for ARM devices (meaning by itself, not pre-installed in a device), porting windows 8 to another devices that doesn't already come with it would be considered piracy.
it is possible to have development to figure out a way for windows 8 to install on this device...but it's not gonna include windows 8 binaries.
I guess these threads need to be merged. http://forum.xda-developers.com/showthread.php?t=1229307
Per that thread they say the biggest issue is the drivers.
why wouldn't MS sell it?

I think what the point was, that MS has 2 options:
Sell the OS as a standalone or sell the OS to OEMs and the OEMs sell the product.
If the latter is the case, you cannot legally install it on something else, that would break the EULA.
Drivers would also probably be an issue, but it's hard to tell until we know what hardware is running Windows 8 whenever it comes out. It's possible that it'll be a non-issue.

Simple,no one would buy it. Chances are,it will be shipped by OEMs with their hardware with custom hardware abstraction layers,if its on consumer devices at all. There is a school of thought that its going to be only for servers. The idea is that taking into account cooling,a rack full of arm servers will have vastly greater performance than a rack full of Intel chips because they can be packed denser. Still,it probably wont be generic,but tied to the particular hardware. It also solves a lot of piracy issues. You cant pirate the software because you cant buy the hardware without buying the software.
It also would give them a leg up on Linux servers. While there COULD be Linux versions ported to the hardware, the manufacturer would probably not give you ANY hardware support,any more than HTC will support Honeycomb on an EVO. They would market it as an appliance rather than a fully configurable server.
There currently are not hardware standards or BIOS/EFI standards for arm that I know of,so a generic version is not possible and I am not optimistic that it will be. Until those things are spelled out there wont be generic hardware like there is with Intel/AMD.

For the same reason that Tablet/Phone makers don't sell devices without an OS. Embedded devices (As the name implies) are supposed to be tied to a single OS.
If you happen to have an MSDN account, you can generally find things such as embedded windows version there. Windows 8 will probably be there as well for ARM. However the biggest problem I think would be hardware working out with it.
ARM for Servers is definitly an option, but MS would be stupid not to offer it to consumers in Laptops and tablets as well.
Currently most tables use ARM and having an Intel x86 in there would not be good for the battery life, ARM is definitly a good option for tablets.
Also Windows 8 will not load Explorer by default, so it will be more power efficient on tablets since it only loads and shows that new Tile (codename was Wind if I'm not mistaken) interface.
It has been demo'ed already on ARM based tablets, if you look at the demo videos on youtube they explicitly mention ARM tablets, and a large part of their plan for Windows 8 is to get onto the ARM based consumer device market.
I agree with posters above though, the ARM version will probably only come through OEM channels. OEMs will probably need to create/tailor a bootloader for their hardware, and preconfigure the OS with the relevant drivers etc.
The best hope for a port will be if an OEM uses hardware close enough that porting their bootloader will be possible and the relevant drivers can be grabbed somewhere. I'm hoping the driver situation will be helped by MS bundling enough generic drivers to get it to run first and that updated/specific drivers can be installed later.

I know nothing about development, but figure if the right devs got interested, it should be possible. I'm watching the build demo, and they had win8 running on a a 3yr old netbook, only using like 270mb of RAM. I know drivers will be an issue, but... anything is possible, right?
Maybe I'm being a little too optimistic.

Really ? Did you do any homework or read any of the blogs about Windows Phone 8 ? I guess not. A key word that you should know is "search" as you would of found your answer.
To answer your question, NO. Window Phone 7 users will get a upgrade to Windows Phone 7.8 and it will give you the new start menu of Windows Phone 8 but, nothing else.

Hey guys,
Firstly please don't get this wp8 forum off to a bad start and keep flaming each other? Respect each other and the rules please :cyclops:
Secondly, from my understanding current hardware specs of wp7 phones are not high enough, do not meet, wp8 requirements so the answer is probably no. The official line is a definate no, wp7 devices, even new ones like lumia 900 will not get wp8 update
Hopefully soon wp8 on WP7 by Custom Rom

Definitely not via an update, that's clearly been addressed by Microsoft. However existing WP7 hardware is surely powerful enough to run WP8. The single core processor is definitely not a problem, and low end WP8 devices are looking to be lower in specs than current WP7 devices.
I'm no expert in usermode on WP, but I know the NT kernel extremely well, and it's more than capable of running on our hardware.

Hahaha. If you read ANY PLACE on this site, it says to SEARCH before posting.
You must not know how to read. This has been a major topic of discussion over every Windows Phone 7 related site.
It does not take a geek or loser like yourself just to spend 2 min reading before posting a subject that has been posted everywhere.
The new upgrade goes to the NT kernal over the WinCE one. That does take more horsepower than current devices can do. It will have native support for C++ and a lot of other modern tech (NFC and others). The current chipset in current devices will not be able to handle it with reasonable performance. As I understand it.
IF some hacker was to create a rom for a current device, it would not support more than 1/2 of the OS and the performace would not be anything worth using unless they stripped everything out.
It's really questionable if a hacker will be able to get it working on current devices and what type of performance. If you really want to know the changes, it's a little long but, it really shows what it can and will do...

Absolutely not true. The NT kernel will run on seriously low specs without any issues. It'll happily run on an old pentium 233 and 32MB RAM without any notable issues in performance. In fact,WP7 hardware is sufficient to run full blown Windows 7, not just the NT6 kernel (assuming the processor was x86 and not ARMv7)
I don't se drivers being a huge blocker as the number of drivers for NT6 is huge, and even in the worst case scenario any drivers we may be missing can be written.
It'll be interesting to see how quickly someone gets WP8 running on a WP7 device.

It's a good question. As I got that from a Tweet by someone at MS. As I understand Windows 8 has a updated kernel that they are using on WP8. Not sure on it, as I thought it was the same as you (I'm a 20 year Windows Systems admin, I know the NT kernel COULD run on 286 machines if needed, not sure on the updated one, just going on what I heard).
It might of been the option of forcing users to have not hard reset their phones (like going from 32bit to 64-bit, no upgrade path) and that would cause a big impact on customer reports. As I have understood from watching the whole MS thing on it, it came down to performance problems that ended it before it started. Some chipsets to support the new OS are not on WP7 devices, so it limits the options current users can take advantage of.
It's not just about the devices and the end users , its' about the PR nightmare. Any press is good but, bad press is a whole different story. In a year or 2 no one will even talk about this. Android does this all the time and even Apple did it to their first gen device.
Who knows. Maybe one of the great hackers here or DFT will make it run on a current device. It makes me question it though.
As long as WP7 devices have been out, Not one WM 6.5 devices (not incuding the HD2 as it was used as a test device for MS on WP7 and drivers were leaked) got a WP7 upgrade OR No Android device got WP7 or the other way around. There are plenty of Android devices or even a handful of 6.5 devices that could of run WP7 fine.
The hackers can do only so much but, time will tell, I just wonder IF POSSABLE (with out MS), just how long it would take.
It will be interesting to see tho...
I do know I am about 95% sure I will be buying one on release, just depending on the models on release.
The reason for almost none of the 6.5 devices running WP7 could be that most of the old devices running 6.5 didn´t have the needed display (capacitive and the WP7 resolution) or processor. Take the Toshiba TG01: resistive display and higher resolution.
btw....moved to Q&A:good:
this will be possible atleast for hd7 and focus 1st gen:good:

Just wondering... Where did you get your info on that ? Your HD7 and focus besides the display and case is almost like every other Windows Phone 7 device (standard hardware across all models).
Even though it has been clearly said by Microsoft that NO 1st or 2nd gen devices will get the update you seem to think the HD7 will.
Maybe it's me but, I'm smelling a little BS here....
Unless Microsoft says that they will be updating or DFT decides to dig in, your not getting a upgrade on any first or 2nd gen device and that includes the HD7 and Focus.
The problem with the kernel is not that it by itself would need that much power to run but rather that they would have to develop loads of drivers for it to work, as they would not be able to use those that already exist for Windows CE.
A bigger problem might be the Bootloader process. The NT Kernel at least on ARM requires an UEFI firmware which is likely to be pretty different from the bootloaders we currently have on our phones.
So the steps would be:
- Develop an UEFI firmware for current WP7 hardware (HSPL needed because it would replace the old bootloader) - including UEFI hardware drivers
- Develop drivers for the chipsets from scratch
- Find out on how many hardware characteristics Microsoft chose to rely that are simply not there on old devices
I'm not saying that it is impossible to do or that it won't ever be done but I guess until it's done almost no one will still be using such an old phone.

Hahaha. If you read ANY PLACE on this site, it says to SEARCH before posting.
You must not know how to read. This has been a major topic of discussion over every Windows Phone 7 related site.
It does not take a geek or loser like yourself just to spend 2 min reading before posting a subject that has been posted everywhere.
The new upgrade goes to the NT kernal over the WinCE one. That does take more horsepower than current devices can do. It will have native support for C++ and a lot of other modern tech (NFC and others). The current chipset in current devices will not be able to handle it with reasonable performance. As I understand it.
IF some hacker was to create a rom for a current device, it would not support more than 1/2 of the OS and the performace would not be anything worth using unless they stripped everything out.
It's really questionable if a hacker will be able to get it working on current devices and what type of performance. If you really want to know the changes, it's a little long but, it really shows what it can and will do...

It's the full streaming event, and it's almost 2 hours but, it's impressive and I can see why they went this route.

Helooo???
Low end WP8 devices will have lower HW specs than some current WP7 devices.
WP8 could run very well on a focus s or HD7 or any other.
There will be custom roms for many current devices, there are many smart guys here that I'm sure will try to do this. Let's hope they will manage to do it.
