I used 8.2.4 subtitles ff.tar and device tree gxm_q200_3g.dtb
After I took an other SD card and made a fresh install with the same files (img.gz) of course. And again the same problem, no boot.
Then I deleted the dtb file and pasted the old dtb file (used with 220.127.116.11) back and the the device was booting perfect again.
I could set the GPU clock to 792 Mhz in display> community extras.
Then testing it with some critical movies and wow!! for the first time no framedrops when enable external subs.
Sometimes the first sub is having the old evil, but after everything is playing fine and smooth, I read this before in this topic, no problem for me.
But... why does the H96 pro+ not boot with the dtb file as you advice?
I am happy allready but could it be more better if this adviced dtb file should work??
The CPU temerature is various between 54 and 61C
And clock speed is showing 1000 and sometimes 1500 Mhz
On my X92 box, if I don't use new dtb.img from 8.2.4 folder I don't get full 792MHz freq.
With old dtb.img, with which my box also boots, I get 400/666 freq and with new dtb.img I get 500/792MHz.
CPU clock freq is of no interest here, you should check GPU clock freq with comamand:
What is correct dtb.img for your box to achieve this OC freq I don't know.... Did you try with gxm_q201_3g.dtb?
I ask because my box boots with both versions q200 and q201...
