Hi Magedanz
Is there a way to fix the ATV remote ?

Not really sure what could be the cause, since I don't really mess with the remote in my custom ROM other than remove the initial pairing requirement (which causes problems for everyone using the original IR remote). Are you pairing it via Bluetooth?

No, i use stock firmware without problems for d?cember, i found the remote is very slow when i click.

Edit : i've test with old firmware it's okey, do you know the problem ?

Is it the same behavior in the stock OEM firmware?

Hello Magendanz,

Fiesta, thank's for your rom and your work. I've two box with your rom (km9 and m8s).
i've problem on km9 with remonte, when i push continually down or up juste go one Time up or down, you understand ?

Edit : i've test with volume UP and down, same problem.


Thanks for help

This was a common problem with the Mecool M8S Pro series, but I thought they'd fixed it in the KM9. Sad to see that doesn't seem to be true.

Hi Magedanz , my KM9 was working fine , it started overheating i took apart the box and the IC S905x2 was getting hot ,The box boots and work for less than a minute and then keeps restarting.

update:
i was doing some tests , i placed a piece of playdoug between the board and the case to push from the other side the board against the IC 905sx2 to the heatsink then i flippled the box and placed a small fan with a circular plastic rim to pull out the hot air , also hard wired the network to prevent wifi heating and seems to be working now , hope it solved fro other users

I made an sdcard with this method:
- https://forum.freaktab.com/forum/tv-...upt-bootloader

and i selected the "erase bootloader" in the burning tool and i managed to flash this ROM successfully. Dont know if the sdcard even had any effect, it was probably just the erasing of bootloader that did the trick. Anyway works now, maybe we should warn future km9 users to stay away from "boot to bootloader" option

Remember these u211 and u212 reference board are incredibly finicky when it comes to USB cables, so I recommend you try one with a ferrite core and braided shielding. My old male-to-male Type A USB cable that had worked for years on other devices just allowed too much signal noise for the KM9.

Also, this is why I removed the Reboot to Bootloader option on my TWRP build.

Hi, i have a KM9 with android 9.0 and it was very buggy and most apps from playstore could not be installed. So i wanted to try this ROM but i had some trouble getting my PC to recognize the device at first. I was booted into recovery and tried the "reboot to bootloader" option. Well now my KM9 is stuck in a boot loop... It seems just selecting that option crashed the bootloader?

- I tried wiping/factory restore, no effect.
- I finally got my PC to recognize the device and tried to flash this ROM with the usb burning tool but i get a diskinitial error at 7%
- i tried flashing from sdcard/usb but it just boots into the recovery without automatically flashing like its supposed to. I used the sd card maker tools from this forum and I tried fat32 and ntfs.
- recovery does not mount sdcard/usb when i try opening them. sd card errors with invalid argument and udisk just doesnt show any files.

Did i perma brick my box just by selecting "reboot to bootloader" ? Help much appreciated, thanks.

I've had one on order for over a month from Gearbest, but it still hasn't shipped. I'll need to look at the hardware to say anything further. These Google Certified boxes tend to have locked bootloaders, which limits what we can do.

Guest , sorry to digress, any chance of doing a custom rom for the KM3 any time soon please?

As a rule I don't play these games trying to deceive apps into running by spoofing a different environment, since it's usually a losing battle. I'm sure there are tricks that might work for a time, but I'll leave that to others.

However, you can disable debugging (and all other developer features) in the Developer Options menu.

Thanks Megadanz, great job. You help to make a serious tool from a toy.

I have installed your ROM on KM9, but I have an issue with this ROM. Maybe you can help me.

For some Channels (e.g. HBO) does my TV provider some checkings, and I am not able to watch them. The checkings are:

1. is device rooted?
2. is the device in debug mode?
3. is some unofficial ROM installed?
4. is some app for RAM debugging installed?

I have checked, the device appears as not rooted. Also, I can turn off USB debugging and developer options.

The problem are items 3 and 4. Maybe item 2 also.

My questions for you are:

• Is there a way to trick my TV software, so that it thinks it is official ROM version? (e.g. like hiding root from some apps)
• does some debug app run in background in your ROM?
• is there any other way to turn of debug mode?

Thanks in advance
