What is this for?
This process is for the Lumia 650 RM-1150 sold via Cricket Wireless in the United States
What does this process do?
It replaces the stock Cricket Wireless firmware with the stock factory unlocked US variant firmware that supports NFC payments through Microsoft Pay, enables Double Tap to Wake screen and enables seamless future firmware updates directly from Microsoft along with additional stability fixes.
Microsoft Lumia Update History
So should I proceed?
This process is mainly targeted for advanced users who like tinkering with firmware and registry. I wouldn't deep dive much into the interop unlock or registry editor sideload process. Whether to proceed or not is solely at your discretion.
What do I need/how should I prepare?
- Backup device (download link)
- Download Windows Device Recovery Tool (download link)
- Download Official unlocked FFU from LumiaFirmware (download link)
- Interop Unlock dependencies (download link) credits gus33000@xda-developers
Steps:
- Developer unlock your device from Settings >> Update & security >> For Developers >> Enable "Developer Mode"
- Side load Interop Tools along with dependencies
- Edit following registry entries:
- HKLM >> SYSTEM >> Platform >> DeviceTargetInfo >> PhoneMobileOperatorName >> "000-US"
- HKLM >> SYSTEM >> Platform >> DeviceTargetInfo >> PhoneManufacturerModelName >> "RM-1150_15887" (FYI - this is US unlocked single-SIM variant)
- Check for updates >> the MicrosoftMDG firmware will start downloading >> Reboot to update
- Run this using command prompt to permanently set the product code for WDRT reinstall:
- thor2 -mode uefiflash -ffufile "location of ffu downloaded from lumiafirmware" -productcodeupdate "059X7P2" -skip_flash >> followed by
- thor2 -mode rnd -bootnormalmode
- Run this to perform a final full firmware flash
- thor2 -mode uefiflash -ffufile "location of ffu downloaded from lumiafirmware" -do_full_nvi_update -do_factory_reset >> followed by
- thor2 -mode rnd -bootnormalmode
- Check for Anniversary Update and proceed setting up device as usual
This process has been tested on 3 Lumia 650s and everything has been working as expected. I haven't tried going back to the Cricket firmware and probably won't.
