I bought this device 2 months ago, I'm very pleased with the price / quality ratio that the Blu Vivo 5 offers.
However, the lack of supported Lte bands (2, 4 and 7 only) is remarkable, especially since the mediatek processor mtk-6753 supports the 'worldmode' 4G / Lte feature which means that all Lte bands are supported. This would be just perfect if it would be supported by the firmware on this phone... Especially since I live in an area where AT&T broadcast Lte signals on different lte bands than supported by the Blu Vivo 5.
I have done some research and I have been trying to read out the current baseband flash file and I'm positive that the current (2, 4 and 7) lte bands are enabled / controlled by this modem baseband (MOLY.LR9. W1444.MD.LWTG.MP.V42.P71).
Anyway, I made some progress by locating the files that holds the lte bands configuration in the device. When I make more progress by successfully enabling more lte bands, I will start a new post in the right section of this forum. For now I'd like to ask if anyone has more info about enabling / tweaking the baseband and / or lte bands configuration with mediatek based devices.
There are many threads and info about Qualcomm based devices where the nvram has been tweaked to enable more lte bands. But as far Mediatek based devices, there is not much to find, other than tools (like MTK engineer mode) to display info. So any helpful background info is highly appreciated!
