Thanks but i dont had anymore my lumia 640XL 3G ver doesn't any posibility to get things like WOA or a custom win10m rom but i unlocked the bootloader correctly using and old version of WPI (plus moded WP8.1 and installing apps)
Today I installed 10240 build in my lumia 640xl lte dual sim. RM-1067. Installed the build without unlocking the bootloader. Flash the rom on windows phone 10 final build. with the help of wp internals. Installed whatsapp different versions. None of them worked for me. Only one got worked till otp. After that it is not opening... Exiting. Gb whatsapp and yo whatsapp not working. Tested only two or three versions. After some time developer menu not opening. So only one chance to install apk files through apk deployment tool. There is a glance screen but no option to turned it off. It remains always on. Everything working fine. But windows update getting download. I think 1475 version or like that. Store not working. Will post more.
When you first get to the home screen immediately turn on airplane mode. After that go into settings and check for an update. It should say no updates found. Now you can turn airplane mode off and download app updates. The reason you must do this is because the phone will try downloading a system update but never actually starts downloading. The pending update causes all the app updates to wait until the system update is done. But it wont ever be done.
Before flashing make sure you have a backup ffu. Flashing this ffu will change your product type so to revert back to normal you need to have a retail ffu file for your phone. If youve used the recovery tool before you should have a retail ffu file in C:>ProgramData>Microsoft>Packages.

WARNING: SOME PEOPLE HAVE BEEN GETTING A SECOND SIM ICON ON THEIR PHONES AFTER FLASHING THESE ROMS EVEN AFTER REVERTING BACK TO WINDOWS PHONE 8.1 USING THE WPRT OR A BACKUP FFU. THE ICON WILL NOT GO AWAY AND CURRENTLY THERE IS NOT A SOLUTION TO FIX IT. IT ONLY OCCURS ON SOME PHONES NOT ALL. YOU DO THIS AT YOUR OWN RISK

Lumia 930 unable to find a bootable option. press any key to shut down
I downgraded my phone to WP8.1 and I bricked it. I looked for fixes but I didnt find it cause there're no GDR2 for this phone. Then I downloaded this L930 10240 ffu file and flashed using WP Internals and done! Fixed and working! :victory:
