Nokia Lumia 625 no 4G only 2G & 3G

^ Did anyone try this (from post above)? I don't wonna lose my guaranty just because of experimenting, when hardware spec. are saying that there is no 4G possibilities.
 
Hi, I have purchased a Nokia Lumia 625 in India "059T1M1 RM-941 VAR IMEA IN CV" I don't get the highest connection speed as 4G when I travel to UK or Malaysia when using a 4G enabled SIM. Can I cross flash it "059T454 RM-941 VAR EURO GB CV" and will this enable 4G option? or can I just replace this file "NWP8 simlock 3gstandard bb5 crcA59A.bin" from the Euro ROM to the Indian ROM and flash to the get the 4G option enabled?

It also depends where you travel to in the UK as not everywhere supports 4G yet, and if you are roaming, both networks I think need to have an agreement for 4G access.
 
There is an Indian version of the Lumia 625, and it doesn't use 4G (ROM limitation or HW one I don't know for now).
 
With the latest update, the 4G option is enabled on the Indian Variant as well. Good now we don't have to flash.
 
I'm based in India.
I had the same issue but it got automatically fixed after the 8.10.14203.306 build update.
This is PD update to my knowledge.
