Installing Windows 10 Mobile Tech Preview on Lumia 925 & Old Lumias after downgrading

Howdy Guys,

Windows 10 Anniversary update is out!! Well there is good news and bad news as well. Good News- Windows 10 Anniversary update is awesome and its stability is also good it is available for all mobile as well as for PCs. Bad news is that now old lumia(925,920,820,1020) will not even be able to install threshold build that means no Windows 10 update when you downgrade to WP8.1.

All the registry hack tools for WP8.1 require Memory card so folks running WP8.1 with no memory card are helpless but, but there is a way you can install Windows 10 Mobile. This process is tedious and requires lot of patience. Don't give up!!

Step 1- Install WDRT so that you can get all the necessary drivers. you can easily search for it on google.

Step 2- Install Windows Phone Internals from here. thanks to [MENTION=3254428]Heathcliff74[/MENTION].

Step 3- Check the getting started page of WPInternal.

Step 4- Now first we will unlock our bootloader and to do that we will be using WPInternal.

Step 5- For Lumia 925 you have to select FFU file from C:\ProgramData\Microsoft\Packages\<Your Device Revision>\ Remember to select FFU file of the same version as of the version installed on your phone. If you have an FFU that is of older version than please flash it first with the FFU then proceed.

Step 4- Then download the Emergency Flash Loaders by going to http://lumiafirmware.com. I have included for Lumia 925. It should be a .HEX file.

Step 6- Then select the SBL3 engineering file and to enable ROOT access it is IMPORTANT to Select this file. I have included some files.

Step 7- Now click continue and wait for the process to complete.

Step 8- Now you can Enable root access.

Step 9- Open RegEdit in your PC and click HKEY_LOCAL_MACHINE and then select files == > Load Hive.

Step 10- Now in the dialog window navigate to MainOS ==> Windows/system32/config and select SYSTEM, it will ask for a name and name it such that you are not confused.

Step 11- Now change the necessary keys. In this you have to navigate to Platform-->DeviceTargetingInfo and then need to change

PhoneManufacturer = NOKIA,

PhoneManufacturerModelName = RM-984_1006,

PhoneModelName = Lumia 830,

PhoneHardwareVariant. = RM-984

For Lumia 925 I used the details of Lumia 830 Indian Variant. You can use the supported lumia which is close to your model in terms of spec.

and after editing click unload Hive this will save your data and everything

Step 12- Disable root access and press power+volumeDown key to soft reset and start your device.

Step 13- Download Windows Insider and select preferred ring and you should see an update. Note after various updates release preview ring doesn't work for Lumia 830, so if you are using Lumia 830 or any unsupported devices then please use slow or fast insider ring

Thank You.

I would also like to thanks to [MENTION=4980790]tofuschnitte[/MENTION].
[Windows 10 Mobile] ArkhamX:
Thanks!, but... I'm a lumia 928 user and I can't find a SBL3 file in my case, can you help me out?
[Windows 10 Mobile] gakshat14:
You can use SBL3 file either of Lumia 925 or Lumia 920.
[Windows 10 Mobile] ibbbo:
Hello ArkhamX, did you try to use different SBL3 file?

I also have 928 and need to make the same steps, in order to enable mass storage mode on this device (to allow me to fix the missing Glance after RS Update).

Dear gakshat14, as far as I understand from the official site of WPinternals and around the forum, if you use different SBL3, you can't unlock Mass Storage Mode.

Also, there is a risk to brick your device (despite, that 928 is based on 920, but still).
[Windows 10 Mobile] gakshat14:
if you will go through the video on their official website you can use it. just go to the website then navigate to tutorial and click on creating custom rom and watch it carefully. SBL3 files are based on SOCs so these phone use same SOCs.
[Windows 10 Mobile] djtonka:
Similar but if know little polish :)

[Windows 10 Mobile] ArkhamX:
For some reason, I'm getting an unexpected error... why's that?
[Windows 10 Mobile] mahdi75:
Will it directly update from 8.1 to Redstone? Or 10586 will be downloaded first, and then Redstone?
[Windows 10 Mobile] djtonka:
ok, first Custom ROM done. Fully unlocked based on 586.494 :)

BTW, you can't install RS on SOC8960

[Lumia 625][Custom ROM][Denim][Windows 10] WindowsMania v1 os: 10.0.10586.494
[Windows 10 Mobile] gakshat14:
It can be due to driver issues

---------- Post added at 10:35 AM ---------- Previous post was at 10:34 AM ----------

I just did and it's working fine.
[Windows 10 Mobile] Nightsteed:
I have RS running on a 810 and a 928 lol.
[Windows 10 Mobile] Odin9126:
Hi,

I just followed your step by step and I want to thank you !

I tried multiple time before and I was not able to update my phone as I pushed an app on it.

Thanks for all the steps described and a huge thanks for SLB3 files !

:good:

On my phone it's actually downloading a newer version of WP8.1

I guess W10M will be the next one :)

Edit : FYI, after the update Insider app was not working anymore and Windows Update said : No update available.

I simply restart my device, then seems like an new update is avaialble. Should be W10M.
[Windows 10 Mobile] djtonka:
try it now, where is now CABs for this SoC, install it form th2
[Windows 10 Mobile] mahdi75:
Was the upgrade successful? Were you directly upgraded to 14393? Or 10586 came first?
[Windows 10 Mobile] Odin9126:
So the process was successful ! :)

I was under WP8.1 Cyan (restored by WDRT) > Updated to WP8.1 Denim > Updated to W10M TH2 > Updated to W10M RS1

It took me :

15 min to restore to Cyan

15 min to go to Denim

45 min to go to TH2

45 min to go to RS1

Plus all the manipulations you have to do with WPInternal, all the system update to download and then update all system apps...

It's about 3 hours to get all working (also depending on your connection speed, mine is about 2Mo/s)

I have to say it seems to be working well, but still not as smooth as WP8.1 unfortunatly.

At least we can enjoy a fully fonctionnal W10M and hopefully a lots of new apps (Instagram, etc...)

Cheers

PS : If after an update the system doesn't find the next one to install, simply give it some time and restart your device. I suspect Windows Insider app to be reinstalled after each update.
[Windows 10 Mobile] tofuschnitte:
did you do a hardreset after reaching the newest rs1 build? give it some time after that (~12 hrs) and reboot it. my 920 is in most cases as fast as it was with 8.1, th2 was slow compared to that
[Windows 10 Mobile] raghav9 9:
I had successfully updated my Nokia lumia 1020

Correct HEX File?

Thank you for this guide. The hex file on on lumiafirmware.com for my Lumia 925 RM-893 is FAST8960_CATWALK_AMERICAS.hex which is different than the one included in the post. Which one should I use?
[Windows 10 Mobile] Stealing_heart:
The one which you found on lumiafirmware.com FAST8960_CATWALK_AMERICAS.hex

Need quick help about the step number 11

What is "the necessary keys"??? How can I check whether data is saved or not???

Is the solution working on L520???

Thanks a lot
[Windows 10 Mobile] mac_pry:
how you've solved this situation? can you post a step-by-step guide for that? It is necessary another System installed inside the PC?
[Windows 10 Mobile] GeoffreyK:
This is a known issue with older Lumias on Redstone. The only "workaround" is to leave it on "Auto" brightness. This setting works and is pretty effective at allowing the brightness to change according to the ambient lighting conditions.

4G not showing after upgrading to Windows 10 preview

Sir I tried looking for the entries but couldn't find them. I went into root access and loaded the hive and there were no connectivity folder please guide me................ one more thing while getting into root mode i get a message on WPinternals "Failed to get root access on EFIESP! Check the OS version on the phone and verify the compatibility-list in the 'Getting Started' section". But still I get the access to root. Please guide me through in getting my 4G option back its 3G&2G only.
[Windows 10 Mobile] Stealing_heart:
Most easiest way is to roll back to WP8.1 then get 4G update and then install windows 10 you will get 4G option.
[Windows 10 Mobile] colossus_r:
Its the way i use it but Its not a solution for me.

Thanks for the answer.
[Windows 10 Mobile] augustinionut:
Wptweaker.
[Windows 10 Mobile] jimmyjakhar:
I have tried everything even downgrading to WP 8.1 and upgrading again still no 4G
[Windows 10 Mobile] Stealing_heart:
I don't know dude!!
[Windows 10 Mobile] Ocasek:
Funny

Windows 10 is working good in my Lumia 928. I found it curious that after changing registry to Lumia 830 as per OP's instructions, my 928 would identify as Lumia 830 for a few days in the About and Extras & Info screens . Now, a week and a few updates later it shows as Lumia 928 back again.

Anyone knows why is that? Will I stop getting updates because of it?

Thank you guys
[Windows 10 Mobile] Stealing_heart:
Yes you will but you can always change your values again.
[Windows 10 Mobile] yusufkeskin:
I have a Lumia 925. When i see this topic first I really excited and felt myself lucky. But it didn't worked. I tried the method after WDRT. WPI program stucks at the emergency download mode screen. I am using the same sbls3 files, same catwalk and my phones original ffu but it stucks at that screen. I am hearing an usb disconnect sound from my computer and it stucks. I already tried with different usb cables. Any ideas? It became a great pain to me. I was unaware about unsupported phones situation so returned to wp8.1 but regret it entirely.
[Windows 10 Mobile] Alin63992:
Hi! I have the same problem with Glance. Can you tell me how can you fix it? I have Lumia 925 but it is probably the same (somehow)
[Windows 10 Mobile] Stealing_heart:
It worked for me, I would suggest to try different PC.
[Windows 10 Mobile] dipayans24:
I want to unlock the bootloader by going back to 8.1

Any user can help me out by answering these questions.

Q1. For 925 users in india,the upgrade path is 8.1>8.1.1>4g update>10586.107.correct??

Q2. The available ffu for 925 is WP8.1(not 8.1.1), so i have to use that only to unlock bootloader?? or can i use 8.1 ffu file to unlock after updating to 8.1.1??

Q3. Does 'enabling root access' require a ffu file(don't know as i am new to it)??

Q4. After enabling root access, do i need to disable it before updating to 8.1 update 1/10?? or it can update w/o disabling??

Q5. At any point of time, do i need to do 'disable root access' & 'restore bootloader both'??
[Windows 10 Mobile] Stealing_heart:
ans 1. Yep if you want 4G then that is the way.

Ans 2. Well I tried that way also and it worked so you can also try.

Ans 3. IF its asking then yes it is required but more importantly engineering SBL3 is required.

Ans 4. No you don't need to. It can update without disabling.

Ans 5. No you don't have to.
[Windows 10 Mobile] yusufkeskin:
Thanks for the advice. I tried with another pc but didn't worked. I think there must be a problem in my usb connection circuit in my Lumia 925, but WDRT is working somehow. Still disconneccting at the emergency download stage.
[Windows 10 Mobile] pradeepn17:
Will we be able to just change it from regedit hive or do we need to start the process from scratch i.e. by using WDRT & going to 8.1 & the entire process...? Please let us know
[Windows 10 Mobile] jayb800:
Hi There. I hope you managed to fix your issue? In case you haven't, I suggest you try reflashing your phone using Windows Phone Internals tool.

Lumia 925 firmware available from lumiafirmware site (look for RM-892)

Windows Phone Internals available from WPinternals site

Windows Phone Internals videos on YouTube (look for videos from user HeathcliffXDA)

(sorry, not posted enough times to include URLs)
[Windows 10 Mobile] Stealing_heart:
I had this problem with my laptop too but when I tried from my friend's laptop it worked and my friend's laptop didn't have anything pre-installed and I would also suggest to insert correct SBL3 file and try re downloading the file and then try with the new one.
[Windows 10 Mobile] Stealing_heart:
You can do that as long as bootloader is unlocked, in Windows 10
[Windows 10 Mobile] Mrwizard0:
After I did this my camera stopped working and isn't even recognized. Is there any place to get/reload the drivers?
[Windows 10 Mobile] Stealing_heart:
Which model did you try this on??
[Windows 10 Mobile] Mrwizard0:
the product code is RM-893. Last night, it did another update for windows 10, and now it works again. I'm assuming it just installed badly and the new install cleaned it up. thanks for trying to help though.
[Windows 10 Mobile] nhrpress:
hey dudes

I installed windows 10 mobile on my Lumia 925 by changing the registry to Lumia 830. but after one week my phone suddenly stopped working and it is dead now, it happened in midnight! now I am gonna follow the tutorial about unbricking without JTAG that was described in another topic

do u have any idea if I should use the emergency files of Lumia 925 or Lumia 830 now?

however I tried both and they are not working.

will be great if someone help me what to do!

thanks!
[Windows 10 Mobile] dipayans24:
Let's see, can you answer the following:

1. Does it boot (lights up)?? If no, try holding vol up(or vol down) after you connect to your phone's charger (should show a lightning symbol)

2. Does the phone is recognised by wdrt??

3. What was the build number when it did happen??

4. Did you restore your registry back to lumia 925 after you update it to RS1?

Even i am having a 925 and updated using 830 registry, that's why i am interested.

and you should be always using 925's emergency files.
[Windows 10 Mobile] nhrpress:
hey. i did not change the registry back to 925.

when i connect it to pc, the microsoft logo's light is on for some sec. usb connection sound in pc also is heard and it shows that phone is connected with driver of QHSUSB_DLOAD, but phone is dead and even not vibrating. just the light is on for a short while. when it is connected to pc and I press power+volume, the light is on again for some sec. WDRT does not recognise phone at all, and it does not have lumia 925 in its list.

btw i forgot the last build number, but it happened one week ago and I was in fast "mode" to get new builds.
[Windows 10 Mobile] dipayans24:
okay, that shows phone's battery has gone completely dead.

you should have restored registry back to 925 and it looks like that your were downloading 14926 overnight and might have been run out of battery while installing it as you were in the fast ring.

now, you can flash an wp8.1 ffu through wpinternals or nokia care suite. either way you need to have a ffu rom. But before that your phone needs charging so keep pressing volume up button untill you get a lighting symbol after connecting it to charger.

And keep us posted if i had guessed the situation or have you found any solution.
[Windows 10 Mobile] nhrpress:
thanx a lot for you respond. you mean do I have to charge battery before using Nokia care suite or WPinternals? and if I plug it to charger, the dead phone is charged?

ps: when connecting to charger, the MS logo light blinks for less than one sec.
[Windows 10 Mobile] titi66200:
It seems that your battery is totally discharged.

Let your phone plugged to charger and wait.
[Windows 10 Mobile] dipayans24:
yes, you have to charge your phone and that also upto 40-50% to get recognised by wdrt/nokia suite/wpinternals. I remember some rs1 build had caused similar issue for L550 (please search for that) and many websites did post

the troubleshooting.Keep your phone connected to charger for atleast an hour and see what happens.Get us updated about the issue.
[Windows 10 Mobile] nhrpress:
I charged the phone for some hours and then tried again. nothing special happened. WDRT, Nokia care suite and WPinternal do not recognize the phone.

when using emergency files, I get this error like always:

As you have messed up your phone pretty badly, you can try for a last time from my side to install a custom rom if you have boot loader unlocked.

Hi guys,

I successfully updated my Lumia 1020 with 930 settings. Everything seems to be ok except Glance screen. I tried to look all over for the issue but no solution. When I click it opens and close immediately. I tried sysapp pusher but no luck. Any other recommendation?

Build 14393.189 and after factory reset...

Thank you

EDIT: I managed to get it worked...

[Windows 10 Mobile] nino90res:
i have unlocked bootloader on my Lumia 920. But it stopped responding during root enabling. i used soft reset to restart the phone and now when i click Enable root access it shows a message:

Failed to switch to Mass Storage Mode. I used SBL3 engineering for Lumia 920. What should i do now?

Also, when i try to select the SYSTEM file in the regedit i get message: File in use. And i can't do anything.
[Windows 10 Mobile] Foto-AG:
Hey.

I think a USB Driver for the Mass Storage Mod is missing

Its a good idea to install Windows Device Recovery Tool...It installs ALL the Drivers you need.

Hope that Helps you out. Let me know...

Watch my Video too..

https://www.youtube.com/playlist?list=PLxKMSSBRUsxE_k5stHhLvfy8GyS--c6Fp
[Windows 10 Mobile] nino90res:
Ok, thanks man! I'll check your tutorial.

But i had installed WDRT already....i don't know how it failed to install a driver?
[Windows 10 Mobile] nino90res:
i was doing the same as you did in the tutorial and i still get the same message: Failed to switch to Mass storage, when i click the Enable Root Access button.
[Windows 10 Mobile] Foto-AG:
There must be a different you did and what i showing in my videos....

Have you the same ffu Image on your Phone thats stored in the "your_ffu_here" folder ?

Have you the correct FAST8960_CATWALK.hex file ?

Have you the correct Engineering-SBL3-Lumia-925.bin ? There are some bin files on the Internet they didnt work, the correct

bin file must have 325kb, there are some files out with less 325kb...so pls double check

Did you unlock the Bootloader first ?

For a correct unlocking you MUST have the same ffu file in your Folder and flashed to the phone !

Have you installed WP8.0 SDK Tools Lite Setup Av1.20.zip AND WP8.1 SDK Tools Lite Setup Av1.00.zip ?

So sorry for my questions, but there must be an error in your configurations ....
[Windows 10 Mobile] nino90res:
I used the SBL3 file from your link. Yes, i installed WP8.0SDK and WP8.1SDK.

I manage to unlock the bootloader successfully but root access don't work. It gets stuck trying to enable root access.
[Windows 10 Mobile] Foto-AG:
Okay..then i give up, i have no more ideas..

Only what you can do is to start over...flash it again with a new ffu file and do all steps again...

Sorry mate.
[Windows 10 Mobile] nino90res:
No problem buddy, thanks for your help and a great tutorial. I guess i'll do it all over again.
[Windows 10 Mobile] Foto-AG:
I think this is a good idea ! Hope you have luck now..
[Windows 10 Mobile] umair_819:
cant get redstone

Successfully update to win 10 but cant get win 10 RS on my lumia 625. i use lumia 830 detail. can i use lumia 950 detail??
[Windows 10 Mobile] Foto-AG:
I think you can´t do that with Lumia 950 detail. The 950 has 3GB Ram..i think you will get the wrong Windows 10 made for 3GB Devices....

But you can test it out...
[Windows 10 Mobile] umair_819:
:laugh::laugh::laugh: This is working for me, i was use Microsoft Lumia 950 detail and after remove insider program, my phone officially update to win 10 14.393.106 :)

i ask one more question that i have lost my lumia 625 detail how can i get my Nokia lumia 625 RM-941 detail back .??
[Windows 10 Mobile] msnguy:
Hi all!

I tried this method and it kinda worked... After a lot of hours! It seems that the SBL3 file of the Lumia 620 is corrupted. I've surpassed that by making a Custom ROM with built-in ROOT support and that works...

Now I don't understand what is ment by: "SStep 10- Now in the dialog window navigate to MainOS ==> Windows/system32/config and select SYSTEM, it will ask for a name and name it such that you are not confused.". I've tried that, but Windows Explorer keeps telling me that "SYSTEM is in use". How can I change this?
[Windows 10 Mobile] Stealing_heart:
One thing to troubleshoot is this first open regedit then click HKEY_LOCAL_MACHINE then select import now navigate to desktop or anywhere else (Remember do not enable root access). Now enable root access and then repeat step 10 now it will be open.
[Windows 10 Mobile] Biosek:
It worked! Thanks!
