Thanks very much to all Masters for the advice!
@ Littlesat - That’s great news
@ Pr2 - In my case is it is able to detect the flashdrive and show the word flashing on the Lcd display. But it never ends and after you stop by switching off the electric supply, the old image is still working. Please tell me what you think might be the problem?
@ Erkman - Noted, but it is able to read the flashdrive.
@ 40H3X- Yes, the flashdrive I use is good because I did try on other stb.
@ ColinB – Great news, so if the image I am testing does not have a built-in option for local flashing, I could use this method. Please tell me how to find out whether I have “ofgwrite” installed?
@ Betacentauri – Thanks again for the precise instruction.
@ ColinB – I will try doing this first.
@ Littlesat – Thanks again for the much easier instruction.
@ ColinB – Thanks for the confirmation on the instruction and the appended process sample.
@ Betacentauri – Thanks again for the advice.
Best Regards to All
