[Q] Is it possible to flash WP Tech Preview to your phone? - Windows Phone 8 Q&A, Help & Troubleshooting

In other words if i was on a fast ring build and wanted to get back the slow ring build is there anyway i can have a backup to flash rather than returning to wp8.1 and downloading the windows insider app all over again?

developer unlock to full interop unlock ? possible after Tango ?

I've been running around in circles for hours, is it possible to go from a developer unlock to a full interop unlock -after- having updated to Tango 7.10.8773.98 ? I can load some XAP's, but root tools and wintt fail.
I had to format my PC and lost my backup.
I'm sort of in the same boat as you. I will be going to my local at&t device support center and getting my phone flashed. I'm hoping the guy there can use the oldest rom he has and or give me a copy of it. I'll post results.

no is the short answer if you have already got the newer firmware, the Windows build has little to do with it,although the tango builds do phone home to relock but that can be prevented
dev unlock is not interop unlock, which is needed to access high privileged functions
if you didn't update the firmware but you did let it relock then simply reapply the unlock and then apply the relock prevent xap, but I suspect you have already tried that suggesting you have the new firmware as well

perhaps ATT will flash the older ROM, I doubt it though and I doubt it even less that they would give you a flashable copy
but stranger things have happened so lets (hope) wait and see
Not what I really wanted to hear, but that's about what I figured/expected. I can't imagine going into AT&T & finding someone who had a clue about re-flashing a WP device.

change the device ID to a nokia
goto HKLM system platform
change OEMdevicename to Lumia 900
OemName to NOKIA ( that is case sensitive)
MODeviceName Lumia 900
that will stop the Samsung update notification and also let you use nokia apps
oh before you change them can you post what yours say? im curious about something

[Q] Windows Phone 8.1 (Nokia Lumia Icon)

Hey everyone, I'm new to these forums but was recommended by a friend. He said that if anyone knew how to do what I need to do, this would be the place so I appreciate any help given.
I am looking to wipe out my Nokia Lumia Icon which has the Windows Phone 8.1 Dev kit on it and put on Android. I tried Windows Phone out but there is still a few kinks that need to be worked out before I fully commit. I would normally just go get an Android Phone but finances don't currently permit and the hardware on this phone is nice.
Thanks

Hi,
If I understand correctly, you want to install Android on this phone? If this is so, then you can not.
By cons, I do not quite understand "Windows Phone 8.1 Dev kit" You mean the Preview for Developers?

Yes, I was looking to wipe off Windows Phone 8.1 and install android. Any reason behind why you can't do it? Just software/hardware compatibility or what?
I did mean the preview for developers.
Thanks!
... you're awfully new to this smartphone thing, aren't you? With *very* few counterexamples, what you're asking for is almost never possible. Without going into the technical details:
1) Most smartphones have locked bootloaders. WP8 devices won't load any OS without a MS signature; good luck getting one of those for your Android image.
2) There's no "installer" for Android (or for WP) the way there is for Windows 7 or Ubuntu or something. You have to customize an Android image with device-specific firmware, then flash the whole thing. There currently doesn't exist any Android-compatible firmware for the Icon.
3) Most important of all: SEARCH BEFORE POSTING! It is literally the number one rule on this forum. Lots of noobs have asked this question; it's annoying answering them over and over again.
If you want to install Android on Lumia Icon, why don't you just buy an Android phone ?

Install Windows 10 Mobile on unsupported Lumia

Hello everyone,
I am interested, is there any way to install Windows 10 Mobile on Lumia 925? Maybe some hack or editing the registry will help? Please help me ))))
Thanks!!!

Install the Windows Insider app and select the release preview ring.
No need to mess with the registry.

EDIT: It now started downloading .164
One more question: What about Redstone builds? How can I install them?
Thanks again!
For Redstone builds you need to fake an entry in the registry.
To be exactly in HKLM-->SYSTEM-->Platform-->DeviceTargetingInfo change the entry in PhoneManufacturer from NOKIA to MicrosoftMDG
But beware, major bugs can occur since your device is not supported officially.

I have a HTC One M8 Windows running 10586.164; that said if you're attempting to run the very latest builds which as of this typing is 14295. Microsoft releases a list of supported devices and the Lumia 925 and the M8W are not on the list and trust me, I'm not happy about their decision and I blame HTC too; a two year promise that has been deliberately broken and for HTC users this is twice and I don't care what some post about their decision being faired; I'm sick of the general device manufacturers thumbing their noses up at us and if the Tech Previews work on our device then why can't the gold release be made to work on ours too.

Hi!
I can't install redstone on my Lumia 520,because i can't install vcREG and CustomPFD.
I've set my phone to developer mode in the developer options settintgs page,and after that i tried to deploy vcREG and CustomPFD to my phone with application deployment tool from windows phone sdk 8.1.When i try to deploy vcREG,the app deploy says the app manifest could not be loaded or not valid,and when i tryed to deploy CustomPFD it throws this error code: 0x81030120.what can i do?i have 10586.164 build of w10m,and i've tried any other methods (for example root tool's interop unlock),but nothing worked for me :/

Hi,
First of all before you will attempt to install Redstone on your device I want to say to you that Redstone on my Lumia 925 was not stable enough. Yes, it was faster than 10586.164 build but it had some bugs listed below:
1) When SIM card is inserted you can't get any notifications and when you try to download app from the store, store freezes. If you will remove SIM card from your phone you will get notifications and store will work properly.
2) If you will reset your phone you will stuck on Welcome Back screen. (If you want to avoid that you need to remove SIM card from your phone)
2) Phone has also charging bugs.
3) Phone restarts very often.
4) Sometimes phone can't find any Wi-Fi. (Restart helps)
So this are the bugs that I noticed when using latest Redstone build on my Lumia 925. If you want to install it anyways I have some suggestions.
1) Restore your phone to Windows Phone 8.1 and ensure that extras+info will not get any update.
2) Install only Windows Insider app and choose Release Preview.
3) When you will install build 10586.164 make reset and again don't update extras+info. (Turn off auto update in store)
4) Choose Developer mode and deploy vcREG. Before you deploy CustomPFD go to templates in vcREG app and click on first and fourth checkboxes and hit apply(or something like that) then deploy CustomPFD.
If you will update extras+info you will not be able to deploy this apps. If you will deploy CustomPFD without using vcREG you will get error: 0x81030120
If you have further questions I am here. ))))
Does anyone know if in the future 520 will be able to update to 14295 without registry hacks? 10586 is unusable for me since it has the bug that prevents installation of extra language packs/keyboards
I was JUST about to flash it and read this. Thanks for the info. Wondering if future builds will be more stable.
Also, say if I flash this, can I revert back to either 8.1 or 10 Preview?

Yes you can revert to WP8.1 and then install W10M preview.
Also not every user had this bugs... Maybe if you will update to W10M you will not get this bugs... But it's risky...

Then I am not willing to take the plunge. I was planning to flash a FULLY working ROM as I was going to give my 925 to my Mom.
But if that is the case, then I might just wait for a fully functional, stable ROM.
What say/?
Update

Thanks for help I've installed Redstone,but it produced a lot of bugs...wifi adapter not working good,mobile data completely not worked,lock screen service seemed to stop after some time...i've used wdrt,and now i want to install w10m 10586 to my phone,but it's not working.i've set the insider app to fast ring,and restarted the phone,but it says it has no new updates.what can i do?i really want to install w10m 10586 :/

Yes it's W10M build 10586.107. When it will be installed check for updates again and it should download build 10586.164. This build is very stable and useful for everyday usage. ...And also I don't understand why they removed Redstone builds from older Lumias with 1GB of RAM, it was very fast on my 925(Except of Bugs)... Lets see what we will get in future...

Unfortunately, that's not true. With 10586 you can't download language packs/keyboards (at least not the ones that include the swype functionality). Anyways, you didn't answer my question - can I expect to be able to install 14295 without registry hacks on 520/521?

LUMIA 925 ROOTED - Customization possibilities

Hello there,
I have questions about my rooted Lumia 925.
I bought it used, with the latest Firmware. Then I loaded up the correct Firmware with Windows Device Recovery Tool, then I unlocked the bootloader, and now I have root access.
I wanted to load up Win10, I haven't made yet, as my phone works fine.
My very 1st question is: IF I'll be successfull with the OS-update, will I lose the root access later on?
I know I could flash the phone back to Win 8.1 but actually the very annoying part is to customize again the device.
Moreover I have a huge problem with "Back-up" built-in function of my WinPhone. I NEVER had a successful back-up of app, settings and SMS... Fortunately my contatcs are secured as they are synced with my account, but that's all.
This bring me to the 2nd question:
ANYONE HAS N IDEA HOW TO FIX THE BACKUP PROBLEM?! ... my phone backs-up pictures and Video on OneDrive BUT NOT the Apps and Settings and SMS...
I got this idea: since I have no chance to back-up my data and settings, what IF make a Back-up of all partitions let's say once a week, following this thread https://forum.xda-developers.com/nokia-lumia-520/development/make-backup-windows-phoneguide-t3628612 or using WPInternals, do I keep my contatcs/sms/settings/apps and so on ?!?
Anyone can confirm this ?
3rd question concerns UPDATE.
since i loaded the firmware 3051.50009.1424.0010 I keep getting this annoying message "there is a critical update, do you want to download it?" If I press on "agree" the phone gets the Firmware 3051.50009.1451.1011 . Then I lose all superuser rights... I tested it.
Is there a way to DISABLE the update completely? Like on Windows Desktop ?!?!
I have to say I got lucky here.
WPINTERNALS warns :
Updating your phone
After you unlocked the bootloader or enabled Root Access, you MUST disable Windows Updates on your phone. Future updates may corrupt the SecureBoot modifications and your phone may not boot anymore.
After you unlocked the bootloader or enabled Root Access, you can only update your Windows Phone by flashing a new Custom ROM which is based on the latest OS version.
Well I did this:
With "ROOT ACCESS ACTIVED" I pressed on agree to get the critical update. The updated failed. The Package has been downloaded but could not be applied (ERROR 800..... don't remember the error-code)
With "ROOT ACCESS DISABLED" the update has been made w/o errors.. and I had for a while the 3051.50009.1451.1011 ... no bootloader corruption !!! , then switched back to 3051.50009.1424.0010 to keep root access.
BUT can I get rid completely of this annoying message about the UPDATE !??!?! I do not want to challenge my luck again.
OR can I block completely the Win-Update process ?!?
OR can I force the phone to check on 127.0.0.1 instead of checking the Microsoft servers thorugh a registry modification?!?
OR could I modify the HOST file instead !? If I would know the server name, I could try to limit the contact by adding 1 line to the HOST file, something like: 127.0.0.1 windowsupdate.microsoft.com !?
Would this work!?
3rd question: I searched long about this... it seems nobody knows... well I try and ask it directly: is there any way to change the GUI ?
I want to know IF / HOW throug registry
1) I can change the tiles fill-colors using custom HEX or RGB format,
2) I can tiles outline/symbols color instead of using the annoying WHITE using HEX or RGB values.. (my idea is to make a "total-black" GUI with darkgrey symbols... )
3) If I can change phone FONTS (dream)
4th question:
My phone is branded Vodafone (as it has 32GB memory) I would like to unbrand it and use the nice computer Boor Screen "Energy Star" . I read I have to make actually a Custom-ROM since the splash-screen is part of the firmware. OK. So following WPINTERNALS, I can select a source FFU-file and extract the EFIESP partition and MainOS partition.
WPINTERNALS says: "You can enable Root Access on these partitions"
Well HOW?
If they are not on the phone how can I enable the root access and how can can I customize MainOS if it is on my Desktop Hard-Drive ?!?
I'm sure I do need another tool for that... Any hint for me please?! Anybody?
Then ok... "After you have unlocked the bootloader of the phone, you can flash the custom ROM to the phone". that's easy.
Last question, just curiosity: is there a SHELL in Win 8.1 mobile ?!
It wuold be nice to have sometime a hack-library divided by phone sometime.... hope that XDA mods will think about it.
With WPINTERNALS for WinPhones there is a fully new world to discover.
Thanks everyone for your answers.
In case you decide to reply, please be kind... since I cannot read your mind nor I have any "palantir" nor divination skills, try to explain things esaly.... e.g. as you would explain them to your dog.... :good:
Have unlocked bootloader and rooted old Nokia lumia 925 through WPINTERNALS... As I did not have many apps or games on it I would like to install some but now am stuck for how to get apps to phone or even is there a custom rom I can flash to it?...any help please..
PS: Phone is on windows 8.1 CYAN, I have made a full backup to pc with WPINTERNALS just in case anything goes wrong/
PS:-All fixed now and can now deploy xap

Use Windows Insider app, will get you windows 10 mobile 10586.107 at first. Once you get it, you can take a lot of paths to get AU(14393.x), CU(15063.x) or FCU(15254.x) builds. I've tested all of them on my device and all work well, you'll need to increase the pagefile for the best multitasking experience. I would suggest that, before getting w10m, get windows device recovery tool and run it on your device to get a clean 8.1 rom, once you get it, download windows insider app from the store, enroll and search for updates, this will get the w10m rom download and once it finishes, it will as you to reboot, do it and it will install.
Remember always to have 40% or more battery. And save your photos, videos, etc. before doing anything.
