think i got it sussed why i was getting crashing...... i was using a multi input power supply which i had set to 5amp.... changed to standard power supply and seems all good..... just a note for all....cheers pinky

Glad it's fixed now, since you were the only one with crashing problems.
For others: If you are not using a 3A charger, you are going to experience issues.

For HPH devices the ROM is overclocked to 1.8Ghz, but not for other devices.

1.8GHz it's not overclocking. It's stock clock from original Rockchip SDK. Have no any overclocking here.

Working on o/c on kernel and have found something I think is unusual. In rk3288.dtsi frequency Tables can be found. CPU show what I think is a CPU running at the 1.8 GHZ will need to be set by the user.

operating-points = <

Hi,

Been following this forum for a while before deciding on a new box (I have an old MK808). Finally picked the HPH one with 4gb/32gb and following speedy delivery and good comms from Tina it arrived safely and the first thing I did before even turning it on was flash this rom. I must say this is a very smooth and quick device and the Rii remote is excellent. I only have one issue, installation fails while trying to update su binary and any help is appreciated.

Thanks for the excellent thread guys and this forum in general. It really gave me time to review and decide without actually buying any device.

Usually a restart and trying again to update su works.

The left box works good for me since we do not have cwm/trwp installed.

Excellent ROM

It runs at 1.8Ghz.
For 2Ghz, you will need extra cooling.
Will see if I can get 2Ghz in future ROM.

Have the firefly scavenged one of my wife's dead heli for a heat sink and bought a new fan. Set my board spacers and height of heat sink to mount fan properly. Ready to make some smores or play some serious games.

Looks as though this Rom should work for the Firefly. Waiting for delivery, I have one Question, is there an upgrade for Kernels to run the advertised 2.0Ghz. Been looking. but can't find anything.

In your changelog it syas that ROM 1.2 uses loader uboot 2.17 though but the one included in zip file is 2.15. I am a bit confused

It is actually for the 17/11/2014 ROM, not the 12/11/2014 ROM.
I changed it.

[oldhouse]

No, a different bootloader won't make any performance difference.
Any firmware released after 12/11/2014 doesn't have any improvement compared to this one except to Realtek wifi and the build-in video player, so it's not worth wasting time flashing another ROM.

[mo123]

I have seen that my stock firmware seems to have a more recent loader uboot: RK3288Loader_uboot_V2.15.02.bin . Does it make any difference with 2.15 included in your package?

Yes, there are lots of apps.
If flashing doesn't work, you can just reflash.
You can also use MaskROM flashing(short 2 pins on board) if your device seems dead, so don't worry.
