k510 to w200, possible?

I wish to convert a k510 cid49 onto a w200 cid52, is it possible?
And, in case of success or insuccess, would it be possible to flash back (from w200 cid52 onto k510 cid49), or my phone will be forever a bugged w200?
Unfortunaly k510 fw are cid49-50.

thanks for reading

It is possible.

is it possible to flash back too? (cid52 to 49)

thank you

You can't downgrade CID. But still can flash back software.

but, if I flash k510 with a w200 cid52 firmware how will I flash back to k510?
Firmware of k510 are cid 49 or 50...

let me understand please

You can flash k510 to w200 and vice versa. About changing CID i'm not sure but i think you must upgrade CID to 52. This don't disturb in flashing.

but is cid connected to the firmware or hardware? If I flash with a firmware cid52 my phone will be a cid52 so I cannot flash back to k510 that have only cid49-50 firmware...

isnt it? or did I misunderstand something?

thank you for patience

You can upgrade CID to 50. Is software for K510 and W200 with this CID. But you don't must to upgrade CID, i think.
