Hi Eric,
I was able to unzip the bin files with Un archiver last night.
Unfortunately ,after transferring the files using Pumpkin (which took over an hour ), the 902 still just running stock TP link firmware. I followed your excellent instructions exactly. I am confused. I already has the Ian Canada linear Pro 3.3 and it certainly made a big difference.
Do I first need to flash open WRT onto the 902 and then flash your minimal image recovery file?
Appreciate any help in advance!
