You should check your APN settings.
Is X552-H952A1-M-170426V52 your currrent build number or the build number before you installed the OTA update?
My APN is correct because 3g service operate and 2g also internet
you skipped some questions
were you able to get 4G on the device before the OS upgrade?
and Is X552-H952A1-M-170426V52 your currrent build number or the build number before you installed the OTA update?
then download, install and launch engineering mode apk from playstore
select MTK settings > BandMode
lets see a screenshot of every item under LTE MODE
then also state which network sim you are currently using
