After a long wait, the wait for Android 6.0 Marshmallow update for MetroPCS Galaxy users is now over as a new update with build no. G920T1UVU3EPE2 has been released as an OTA.
The model no. of MetroPCS Galaxy S6 is SM-G920T1, which is tad different from the model no. SM-G920T of T-Mobile Galaxy S6. The phones are exactly same, which is why T-Mobile Galaxy S6’s firmware work on MetroPCS too.
Anyway, there’s a new Marshmallow build available now, which MetroPCS can truly call their own.
Look up for the OTA update under system update in Settings app. If you don’t get the OTA, which could take days or weeks, then just download the update from our firmware page below to upgrade manually.
