    I currently have a Lumia 1520.3, RM-938_lta_lta_905. When I checked my firmware it is 2540.19.15236.45004, and that applies to the India build RM-937_im_india_235. Is it possible I received the wrong firmware by mistake? Technically I should have 2540.19.15053.26003

    Is it through WDRT? If so, no problems whatsoever. Even on my lumia 730 new firmware is installed after hard reset which is yet to be rolled out.

    Not sure what you mean by WDRT but I've used it before with no issues. I just decided to see if any firmware update was available with the new insider production option.

    Nokia Lumia 1520.3 here, never off official.

    Manufacturer Name: RM-938_lta_lta_905
    Mobile Operator: 000-22

    Firmware revision number: 02540.00019.15236.45004

    I was made aware that new Firmware might be available and checked OTA. Found nothing. I then plugged into USB and opened Windows Device Recovery Tool (WDRT) which updated from v3.1.4 to v3.1.5. Then it stated I had new Firmware which OTA could not find.
