[Q] ReactOS ARM port on Rhodium?

Ok, so...
At first I found a ReactOS offical ARM port.
It is here(delete spaces, forum still prevents me from inserting any link): htt p:/ /ww w. rea cto s.or g/wik i/ARM_ Port
At second I don't understand it at all so if anyone are good in this type of thing, tell us is it possible to have it working UNDER HARET?
And finaly at third If yes, is it will be possible to run any applications excluding a orginals one?
And that's all
P.S. There is already a topic here(ht tp:/ /foru m.xd a-deve lopers.co m/sho wthre ad.php?t =791800 ) but it is quite old and not for our device.

Ew, why would you want React on your phone...?

i'd say ehm.. for the heck of it?
don't really think there is a point tho in rOS, both windows that comes natively and android have a massive userbase and for a 'full OS' there is already someone building linux version of Ubuntu.
beside that, the React OS makes use of 'windows' binaries (from what i read on their website.) which are in x86 format as far as i believe, running them on an ARM processor isn't likely to work.
if i'm incorrect please correct me

Not really, all the binaries were written by ReactOS Team and they are open source... So in practise we can compile it and have it running on ARM processor.
And why? Simply. If all the dll's and files can run exe files we should be able to run normal applications like firefox, flash, etc. Maybe not at maxiumum speed(because of alpha build of ReactOS) but still it can be quite useful.
I didn't managed to build it. As far as I read it is imposible beacause of compiler which doesn't compile it correctly, or at all.
If anyone have any ideas how to do it tell us...
P.S. The full source of ReactOS + additional appliactions included is avaible at ReactOS main page.

Well ReactOS to my knowledge doesn't run that well on x86 machines, so I doubt our tired old phones will run it very well...
Rhodbuntu isn't good enough...? I'd say that's your best hope - in theory it will run FF & flash...

ReactOS of course is not the faster system ever but it it a only(actualy) operation system that is in open source and have a fully rewritten binaries, etc.
And BTW you still can't have a flash and Java(SE) running on armel(rhodbuntu)

Ah didn't realize. What makes you think it'll work on React? lol

Theres a possibility. But as I test the recent version out, there are problems with it, so I dont think its a good idea to port. There are issues from clicking to how things are displayed to windows sticking & not listening to me when I click close or minimize/maximize.

WinRT on Nexus 7

Good afternoon!
A few days ago came into my hands one file, it was a way I've found windows rt restore img. Googling found that hardware stuffing differs only display resolution and count-tion of memory (in Asus Vivo RT 2 GB, Microsoft Surface 2GB while the Nexus 7 1 GB), but the problem is that all WinRT tablet is uefi bootloader. Remembering Projects OSX86 and about chameleon, empire efi, decided to port the bootloader on Nexus. Make the type MultiBoot.
who will help me in my endeavors?
Cotulla make with htc hd2 magldr>uefi>win rt (magldr this is custom loader with sdcard boot support) / can we make a analog of magldr for nexus 7?

Hi, I acan't help but don't see why this isn't possible (albeit very hard) as win rt has been run on htc hd2 http://www.xda-developers.com/windows-mobile/htc-hd2-refuses-to-die-now-runs-windows-rt/ however I beleive a custom firmware was written for the very purpose.
I am trying to do the complete opposite and install android/ubuntu on the vivo tab tf600. Best of luck and please post updates if you make any progress.

need people who can write uefi loader/ please write.

Unfortunately I don't have the technical knowledge to be able to help you with that...
But I think I've read that MAGLDR-UEFI was based on tianocore, so you can start with that!
Code:
tianocore.sourceforge.net
But it's an awesome project!:highfive:
I hope you can make it happen! :fingers-crossed:

Just now, we need MS SurfaceRT tablet, and I collect the money for it.

hello my name is mike clery I was wondering any info on a 8.1 jailbreak I really want to install legacy apps on my surface rt so if you can tell me anything its December 26 and still no info on it

Dude. Don't pester the devs. Don't post questions that have already been asked and answered over and over again. Don't, ever, ask for ETAs or similar concerning hacks like this. Leaving aside the simple fact that it's impossible to predict anything of that nature (and thus asking is simply useless and annoying spam), people on here are volunteers doing this stuff in our own time. You are not our boss, to ask for regular status reports or some such thing. It'll be posted when it's ready. No point asking for anything else.
There has been plenty of discussion regarding an 8.1 jailbreak. I get that you're new, but time was, new members of a community had the courtesy to observe, and emulate, the behavior of the older members of the community. At a minimum, check the forum rules... the very first of which is: Search before posting!

cameyo ? work with jailbreakoen surface rt ????
Have you guys heard about cameyo ?????
Its pre pacakge apps taht dont need to be installed to run.
download them and run them, wonder if we be able to use those apps after the RT is jailbroken? any idea ?
search for online . cameyo . com / public - (no spaces)
here is the link to hugh list of apps that can be downloaded as n exe file and run on any PC, offcourse not on rt . i tried. Anyone with a 8.0 surface RT jailbroken devce, wanna try and let us know if they are working ?

Nope. Cameyo is for x86 not ARM and would need porting, as it is not open source that is not possible.

Possible alternitve?
Is is possible to just get a developer license on an rt device and then use your own signing certificate to sign some application (like audacity) then import the certificate into the trusted root authority list using certmgr.msc? If that worked then we could get something going that would work with few risk of problems. Also for anyone else who might find this useful, you can download a windows rt debugger and it has a built In kernel debugger (maybe could be used to jailbreak???).

... And we come full circle. @johndc7, thanks for your suggestion but did you really think that wasn't among the very first things we tried?
The requirement isn't that the binaries are signed. It's that they're signed by Microsoft. Your suggestion does actually work if the tablet is in Testsigning mode - which means, basically, treat any trusted signature as if it's a MS signature - but putting the tablet in Testsigning mode requires editing the BCD (Boot Configuration Database) and the SecureBoot feature prevents any modification to the SecureBoot flag in the BCD. We even have tried complex steps like exporting the BCD, enabling Testsigning on it, marking it read-only, and re-importing it. No dice. Feel free to experiment more yourself, though...
Oh, and as for kernel debug, that's definitely another way to disable the signature enforcement... and it's just as unusable as your last suggestion. Secure Boot blocks the Debug flags in the BCD. You don't need any special software to perform kernel debugging of RT - any build of kdb or windbg from the last few years can do it - but you do need to be able to put the tablet in debug mode to begin with. Again, if you find a way to do *that*, then that would be very valuable.

Another idea........
Hopefully this is something that is actually somewhat realistic..... I have been wanting to run audacity (mainly) on windows rt. Does anyone know if it would be possible to recompile it to run full screen in metro? Even though this method isn't really ideal, it would be something to temporally use instead of having nothing until somebody finds a better way of doing it. I understand that it probably wouldn't be able to be released to the windows store but a developer license could be installed to run it.

Well, at a bare minimum, you would need to re-write the entire UI. Metro apps don't (can't) use the standard Windows GUI frameworks, so any graphical app that isn't completely DirectX-based (which is to say, pretty much anything except games and command-line apps) will need to have their interface re-written.
Then there's the issue of things like getting it to work within the sandbox (you can largely work around the API restrictions, but the privileges issue is a problem) and, unless it is already possible to compile it under modern versions of Visual Studio (a lot of open-source software isn't), you would need to fix it for MSVC compatibility too.
Short version: Not practically.

Possible Alternative
I did find a folder on my RT device called "CodeIntegrity". The path is "C:/Windows/System32/CodeIntegrity". It contains drivers and stl files that I assume prevent the use of unsigned exes. Permissions that are not normally granted on the Surface are needed to disable the files, but if we could somehow do it maybe it would solve the problem?

Not exactly. They can be signed by any certificate listed in the kek or db and not listed in the dbx. So microsoft (though there are different signatures in rt 8.0 and rt 8.1) and the OEM, and any third party that made drivers that are used on the platform (at least in general). But those are just technical details and don't help find a solution all that much.

[Question]Is it possible to install windows 10 on mi6?

Since windows can already run on snapdragon 835,i want to try it out on my mi6.
Is it possible and if so how to do it?

We need to have bios for our devices to boot it directly and since we don't have one, our best choice is to wait for a project on xda (I don't remember the name well but I'm pretty sure you can find easily if you search for it) that ports bios for android devices.
But to be honest even if you can run windows on mi 6 there are 2 bad news for you:
1) The vast majority of windows applications are written for x86 architecture and we have arm architecture, so to run them you should emulate either os or run the app in an emulated sandbox - so no good performance.
2) As I said in 1st one, emulation is a must (if you aren't planning to compile all those apps for arm architecture). Also windows 10's capability of running x86 apps on arm is based on that very emulation method, it runs them on a WoW (Windows on Windows) so there's clearly a hit on performance.
I suggest you to not to expect to have a decent windows system running on your arm device but if you need/want to run more basic windows apps, you can try Limbo PC Emulator. That way you can run some older or stripped down versions of windows with no heavy performance loss. For most of the basic things I find MicroXP project enough but don't expect to be able to run Photoshop on that I hope this answers your question.

I see, thank you ccelik97 for your clear answer.

Help needed to install Windows 10 for ARM32 for Nokia Lumia 2520 RT

Hi guys, can anyone help to install Windows 10 for ARM32 for Nokia Lumia 2520 RT tablet?

Same procedure as other devices but you will have to substitute the drivers with ones from the 2520 aside from qcpep which has to be replaced with an alternative one which I think came from the Lumina WoA project staff (From Lumia 930?). However, if your 2520 has been kept up to date with the latest patches under RT 8.1 then you won't be able to jailbreak it in order to use 15035

Hi JWA4 could you expand on this? Also is it the case for the surface RT as well (latest up to date version can't be jailbreaked) or just the 2520?

The short version as I understand it is that Nvidia screwed up in users favor which makes the Tegra Surfaces immune to permanent effects of the jailbreak killing Windows RT updates. On these devices reversing the negative effects of theses updates is as simple as a factory reset.
Sadly with the Lumia 2520, Qualcomm did the job right and at present there is no going back if a jailbreak killer has ever been installed.
I will try to find the detailed explanation I read and post it here asap.

I was unable to find the explanation that I read but if I find it again I will post.
I could be wrong and there might be more to it but I think the general idea was that Nvida did not implement the mechanism that handles the revocation of previously issued certificates correctly whereas Qualcomm did. On a previously updated Lumia 2520 this prevents the Secure Boot Debug Policy from working because its certificate is no longer going to be valid on the device.

Go to Discord. I discuss all the sub-genes there. The system is not ready for public use. Testsign, secureboot and everything you need is there. No problem using Linux via grub uefi. It is much more difficult to find developers who will do this. And Tales about the impossibility of disabling Secureboot is just a fact of bygone days. The device is now free of these restrictions.
No touch, no modem, no BT, no audio, adreno 330 not work.
But yesterday qcpep and qcpepproxy did not work as expected.
Today they are working as expected.
I will start other hardware devices too. It just takes time.

i need help to install windows 10 rt on Nokia 2520

I know this device is so outdated and all, yet it'd be nice to get some use out of it. Anyone have a proper guide on how to accomplish what @CageOff was saying in order to bypass the security update patches and getting securebooot unlocked. I've tried so many different methods and gotten nowhere in my attempts to get working BOOTABLE USB media for 8.1. No guide clearly explains/points out that the Myriachan's Jailbreak is the exploit specifically intended for the Qualcomm Nokia Lumia 2520 to get the test mode exploit going (if it works). Longhorn obviously doesn't work as it can't install Golden Keys. I went to the Telegram group @CageOff mentions, but there is no way to talk to the person nor any clear info about how he managed to dualboot win10 arm/win8.1 arm. If anyone could shed some light on me here, It'd be much appreciated.

Myriachan is not specifically intended for Qualcomm devices, its just that it can't be permanently patched against but this won't help you for 15035.
I don't have a 2520 but from what I can tell CageOff seems to have booted 15035 on a 2520 but the details are getting lost in translation and a writeup doesn't seem to be forthcoming. From what I can gather even though he has booted 15035 on his 2520, he has done so without the installation of the QCPEP driver and without this driver virtually nothing else will work.
On QCEP - BetaWiki.net
This build does not support the Nokia Lumia 2520 Qualcomm Power Engine Plugin driver. Loading a newer driver for the Snapdragon 800 is mandatory.

The newer driver I believe is harvested from the LumiaWOA project, specifically taken from the Lumia 930 package. It could be worth looking at how WFAv7_Installer installs 15035 on a 930? It might shed some light on the driver ordering, as far as I've been told Qualcomm stuff has to be dealt with in a certain order.
Before you put too much time in to this though remember 15035 is about as much use a chocolate teapot so remember its just for fun. If you spend a week figuring it and actually get it all working in the hope of making an ex-RT device useful you are going to be a little disappointed at the end of it.

That's definitely worth looking into in regards to the "WFAv7_Installer". I just tried the WOA Deployer v2.7.1 and it seems it could be of great use in getting Win 10/11 arm onto this device. Of course, if one can figure out how to access/enter a Mass Storage mode first.
I also read in another forum article that the IOT versions of Windows seems to be more useful for this device, rather than trying to get the standard Pro/Home editions. They also mentioned that one may need to apply the drivers from the original Win 8.1 RT in order to get all of the devices hardware working though. I would personally like to give this a try, but I can't seem to get to the point of being able to install Win 10 build 15035 onto my device. I can't enable test-signing mode, nor disable bootloader with any of the jail breaks available. I get the error code 0x000000000000d (not sure i put the correct amount of zero's there), which seems to give no existing info on the net for that error code, only a few forum posts regarding the variant to that code which ends in "f" which seems to be related to the Surface 1/2 devices.
I know I can format the eMMC properly via command prompt, diskpart, and dism (for Win 8.1 RT), then disable BitLocker (even though C:\ still says Bitlocker Encrypted). Yet, I just can't get the Win 10 media to work which i assume is due to secure boot. Does it make any difference if I'm using the install.wim or install.esd versions of the media?

WOA Deployer is specifically for deploying WoA on the Lumia 950 & 950 XL, it doesn't support Windows 10 15035 or ARM32 devices like the Lumia 2520.
Windows 11 is out of the question, only small parts of it were built for ARM32 (nothing close to a full client) and the bits that were built won't work with this SoC. I don't believe WFAv7_Installer ever had the 2520 in mind, I only suggested it because how it prepares an image for some of the Lumia phones might shed some light on how an image would need to be prepared for the 2520.

That's going to come down to what you define as useful but personally I don't see any point in running IoT on a tablet. At the time of writing only the 15035 client build is available and that's now over five years old. Drivers taken from the RT 8.1 recovery image would be required along with the replacement PEP driver mentioned previously but its possible not all drivers will be compatible with IoT.

To enable test mode you would need either Golden Keys or the Myriachan jailbreak, unless you are lucky then the device you have might not be capable of using Golden Keys anymore. If I'm remembering correctly the Myriachan jailbreak is only useful for running third party applications under RT 8.1 and wouldn't assist in running another OS.

Windows 10 15035 isn't available as an ESD, you would need to take the 15035 installation files and properly add the drivers to boot.wim, install.wim and winre.wim before copying them to USB and attempting the installation. CageOff seems to have installed 15035 without the use of Golden Keys but even when booted the installation of 15035 is useless because he has not added the PEP driver.
