Despite having had a few issues with the volume from time to time, I am still using a Q10 Pro with Android 5 / OFW 1.0.7. A few years ago I installed a Seagate Archive HDD and currently I am using about 90% of the available space (8TB). The media player was not cheap, but considering the availability of a long term support from a helpful community and the relative stability of the system I believe it was a fair deal.
Right now I am contemplating on upgrading to Android 7 and a later version of the firmware. The installation instructions seem to be clear:
stage 1 -> migrate to Android 7
stage 2 -> install the Android 7 OFW version 2.0.0 or higher
a) Having had a few troubles in the past flashing other devices I know that later firmware versions sometimes remove crucial features. Therefore the latest firmware is not necessarily the best option. Which one would you recommend?
b) Should one remove the internal HDD before starting this process and re-install it only afterwards?
Looking forward to your replies, have a great day
