Install Windows 10 Mobile Build 14364 on older Lumias
Recently Microsoft released a new Redstone build 14364 for fast ring insiders for Windows 10 Mobile and as build was only available for some newer selected models (Lumia i.e. Lumia 550, Lumia 950XL, Lumia 650 and for Xiaomi Mi4) so many insiders are certainly upset (including me also). But as there are limitations, there are some weird solutions.
Now the popular modders community XDA developers published a discussion about the trick by which you can get this build on your phone although if your phone model is not listed.
1.1) Download WP sdk tools 8.0 lite :source zippyshare and click on “ ” click “Yes” for every prompt

a)change ” PhoneManufacturer ” = MicrosoftMDG
b)change ” PhoneManufacturerModelName ” = RM-1085_11302 (for Single SIM devices) // *** For all dual sim devices try = RM-1116_11258 ***
4) change PhoneModelName = Lumia 950 XL (single sim) or Lumia 950 XL Dual SIM (for dual)
5)change PhoneHardwareVariant = RM-1085
6) install windows insider from store
Some are also trying Lumia 830 for changing the settings,
PhoneModelName: Lumia 830
Some report even Lumia 635 settings work fine,
PhoneModelName: Lumia 635
7) After that open Windows insider app, the apply for builds select fast ring then your device will reboot as usual and then check for update in phone update setting. You will get it. The update size is all about 600MB.
