[Working]Install Windows 10 on Lumia 820 (ROOT access and bootloader methed)

[sun1000]

Hi
Its not good that we don't have Windows 10 on our old devices and I recently found a trick to "interop-Unlock" old Lumia phones . with "CustomWPSystem_0601.xap" (selecting mix radio app and "vcREG_MIX_RADIO_bootstrap.xap" to deploy) and with registry changes you can get Windows 10 mobile. but for Some people like me ( in Iran ) MixRadio is not available.but don't worry its not going to keep us from getting Windows 10 have a lot of this Tutr all around but this is a full ALL-IN-ONE for Lumia 820
BY DOING THIS THE WARRENTY IS PERHAPS VOIDED DUE TO ROOT ACCESS GRANTTING AND BOOTLOADER UNLOCKING( who knows )
I TAKE NO RESPONSIBILITY FOR ANY BROKEN DEVICE IN OF ANY KIND.DO IT AT YOUR OWN RISK .YOU WILL LOSE ALL DATA DURING THIS
Tested on Lumia 820 RM-825 Running Windows phone 8.1
NOTE : These steps are very much harder than a simple interop-Unlock and higher at the matter of RISK OF BRICKING YOUR DEVICE. So maybe you get confused or etc.. if you are new to windows phone or if you are a non-expert user. READ BEFORE DOING

1- Opt a Stock FFU file or Download via "NSU For reatil" or "Microsoft Device Recovery" . then name should be something like "RM825_3051.50009.1424.0002_RETAIL_im_mea3_287_02_440287_prd_signed.ffu"
pay attention to 3051.50009.1424.0002 part of the name it should be EXACTLY THE SAME WITH YOUR CURRENT VERSION IN PHONE (for you maybe a different number but still should be same in both your device and FFU file you got). If your Version is not the same, flash it with "NSU For retail" or any other tool.
2- Download Zip File from below and unpack it somewhere safe
3-Make sure to turn off your antivirus and HIPS and Auto Sand box if you have any
4-Go to dir where you unpacked the zip file and head t o "Windows phone Internals" and run "WPinternals.exe" you need to be Admin
5-OPTIONAL : Make a backup of your data
6-Connect your turned on Lumia to PC and let Driver get installed
7- Install "Nokia Emergency Drivers" . I used this. its better to restart your PC then.
8-In "Windows phone internals" click on "Unlock bootloader". and Select the folder you placed FFU file and set "Emergency Files" folder from Extracted(ONLY FOR LUMIA 820 <<RM825_3051.50009.1424.0002_RETAIL_im_mea3_287_02_440287_prd_signed.ffu>> FOR OTHERS VISIT THIS AND DOWNLOAD YOUR OWN) file to respected field and at last "Engineering SBL3" (FOR ALMOST ALL OLD PHONES IS IN ZIP FILE") folder to respected field. and hit continue. Follow next steps on screen
IN NEXT STEPS IGNORE ANY DRIVE ADDED TO YOUR PC . DO NOT CHANGE ANYTHING
9-Then hit "Enable root access " in windows phone internal and set respected fields then hit continue. follow next steps on screen
10- at last when Root access is enabled . you will in stock in Storage mode.to Escape press and hold "power+Vol Down" about 10 secent until phone vibrate (this is a soft reset). after all your phone will restart and will normally boot
11- Use "WPV XAP Deployer 2.0" to Deploy "CustomPFD_0600.xap" (You can find both in extracted zip file) (no need for "developer register" due to Root access)
12-Open CustomPFD added to your app list and head to HKLM-->SYSTEM-->Platform-->DeviceTargetingInfo and change these
Single sim only :
PhoneManufacturerModelName " = RM-984
honeModelName = Lumia 830
PhoneHardwareVariant = RM-984
13- Download windows insider and roll in
14- now due to checksum computing during updates you need to Disable root access (BUT DO NOT RESTORE BOOTLOADER). so get back to Windows phone Internal and Disable root access. then rebbot and get back to normal .
15-check for update first one will be preparation and at secent you will get Windows 10 :laugh:
NOTE : your bootloaer will remain unlocked no problem till now BUT if we get any update to change anything to Secureboot then we are probably going to have our devices broken.

I have done this, step by step and it works. Regarding bootloader, what can go wrong? Will there be some updates which will make changes to secureboot?

Yes and no!
Microsoft has abandoned lumia 820 updates long time ago so 99% there would be no more updates but in that 1 percent they may release an update which contains new bootloader and overwrite the unlocked one. In that case depend on the new mechanism the solutions can vary ?
Good luck with your new windows 10 mobile device?

If anyone is getting the Bluetooth issues after upgrading (it disables itself/needs to have flight mode switched on and off etc.) I think it's an issue with the latest build that update is sending (I think the last 3 numbers of the version number are 4xx (469?))

With a bit of experimentation (I have a couple of test 820 boards that have broken sim slots) I found that Technical Preview 10.0.14393.67 seems to work OK (most likely with other issues, but Bluetooth is OK) - this is the one you get by signing up for fast loop at all stages during the upgrades

EDIT - Turns out you need to perform a full restore once you've updated to .67 to get Bluetooth working again.

Hi.
I forgot the password of my Nokia Lumia 820 and I am trying to unlock it using the Aroma file manager. I already downloaded and moved Aroma file manager to the memory card. Now I need to boot my locked Nokia Lumia 820 into recovery mode and go to install zip from SD card. BUT I do not know how to enter the recovery mode in a Nokia Lumia 820. I have tried all these combinations: Power + Volume Up - Power + Volume Down - Power + Volume Up + Volume Down, Power + Volume Up + Camera button- etc, and nothing. could you please help me?

Hello All.. I tried to follow the process to unlock the bootloader of my Lumia 820. But in middle of the process, my laptop crashed
Now my phone is not switching on nor responding to anything. Suggest something to revive the phone.

I'm quite new to flashing in Windows Phone. Is the update done through Windows Insider OR Settings > Phone Update?

Hello All.. I tried to follow the process to unlock the bootloader of my Lumia 820. But in middle of the process, my laptop crashed
Now my phone is not switching on nor responding to anything. Suggest something to revive the phone.

I know it's 5 months already. Yesterday my phone got disconnected while flashing with WPInternals. It was dead. Fortunately, it was detected by laptop. Remember to use original USB cable or compatible. I wasted hours dealing with unbranded cable. Then I changed the cable with Samsung's one and found it working.

One of these three command revived my phone and set the screen to red screen with Nokia logo:

thor2 -mode emergency -hexfile "C:\PATH_TO\FAST8960_ARROW_ROW.hex" -mbnfile "C:\PATH_TO\RM825_msimage_v1.0.mbn" -orig_gpt

thor2 -mode emergency -hexfile "C:\PATH_TO\FAST8960_ARROW_ROW.hex" -mbnfile "C:\PATH_TO\RM825_msimage_v1.0.mbn" -skipffuflash

thor2 -mode emergency -hexfile "C:\PATH_TO\FAST8960_ARROW_ROW.hex" -mbnfile "C:\PATH_TO\RM825_msimage_v1.0.mbn" -ffufile "C:\PATH_TO_FFU_FILE.ffu" -skipffuflash

I turned off the phone by detaching the battery and then I reattached it. Execute this command, then connect the phone to laptop.

thor2 -mode uefiflash -ffufile "C:\PATH_TO_FFU_FILE.ffu" -do_full_nvi_update -do_factory_reset

Successfull flash should changed the screen from red to green. Finally, we need to reboot the phone:

thor2 -mode rnd -bootnormalmode

Im trying to upgrade my Lumia 820 to windows 10, all was good until step 9
9-Then hit "Enable root access " in windows phone internal and set respected fields then hit continue. follow next steps on screen
where my phone just went blank, i assume somethings wrong with the bootloader and reflashed the bootloader again(with Engineering-SBL3-Lumia-820.bin)
but its still the same. So I went with rooting into the rom and flashing the rom, which worked. But now since Mass Storage Mode is not unlocked, I can't unroot without flashing again. Anyway, I downloaded Windows insider and tap on getting the preview builds, but a server error occurs. Confirmed that my date and time are alright, I have also did the registry editing. I have tried checking for updates, but it seems like its just another 8.1 update. What should my next steps be? Any advice greatly appreciated!

Try to change the time several hours backward.

When I tried it, Windows Insider successfully checked for update but it said no update. I have no idea if it was my firmware or the update was deleted from the server.
