[Q] Flashing e250k modem to e250l? topic

Is it possbile to flash other e250x modems to e250L?
I think this is a modem issue.
I'm from Myanmar and I only get 2g connection on my note 2 shv-e250L. (There is no lte here but 3g bands 900/2100mhz Ooredoo, which my phone can't read now.)

Help me brothers. Thanks.
