Thanks to everyone who has replied
On closer inspection of my device the following info was present.
Model- NEO-U9-H
Build- U9-H FW008 20180209
Version- 6.0.1
Android security patch level- 01/08/2016
Thankfully I have FW08 ...I think?
But my android version is old V6
Can I update this ?
If so how?
Will it be worth it?
I have tried to update over the OTA but says there are no updates or server is down
Finally, current release keys are:
MHC19J.20180209
Instruction tells me to do over wifi, using battery with 30% charge and unplug before upgrade, quite confusing.
I know theres a lot in here but it may help in anyone helping me?
