Hello all..How to root Mecool KM3 (4/64) Collective ? Thanks and Happy New Year

[Dicentim]

you need to use this recovery.img ,it's launch from a flash drive https://mega.nz/#F!VtJ1TQTS!hFXf9r8d...w0MOw?V1R1DKCR

Thanks again but we can only flash .zip file from flash drive, so I have to zip the .img file or using USB burning tools ?
And is it the stockrecovery or a custom one ? Thanks.
Your rom seems great hope I'll be able to flash it again.

I found this : https://forum.xda-developers.com/and...to-pc-t3914587
Second post is very interesting as I encounters the same exact problem.

Yes of course I Launched cmd.exe in administrator mode.

I tried the command "fastboot devices" or "adb devices" and nothing appears.
The box is well detected by USB burning tools but not by cmd.exe.

Or maybe it's beause the last command line " fastboot oem reset" failed during the 1st flash...

[b2oba17]

you launch all in administrator mode ?

Hi Bo2ba17, unfortunately your link is dead : https://adbdriver.com/upload/ADBDriverInstaller.exe
I installed this one that is certainly the same : https://adb.clockworkmod.com/

And still the same issue, my box is not recognized by the command lines.
Here is the way my box appears on Windows :



It's ok using USB burning tool but I can't enter any command line.

The first time I intalled your ROM it was ok, I was able to access command line and I could enter :

update bulkcmd fastboot
fastboot flashing unlock
fastboot flashing unlock_critical

I only got an error with the last command : fastboot oem reset
But it was ok the box booted on your rom, but with this slight voice remote bug I decided to reflash again and now no way to enter ant command line.
As soon as I try to enter update bulkcmd fastboot I have the error I wrote in my previous post.

I use the same cable, the same USB port, I even tried on another PC. Honestly I don't understand why... What changed between the 1st time and now ?

Maybe it's stupid but I think that as your rom was root , it changed the recovery and I need to flash the stock recovery to get adb/fastboot commands back. No ?

Or is it possible to install your ROM (.zip format) using USB update ?
If not I'll keep the stock firmware. Sigh...
Thanks.

Hi,
I tried using another PC (Windows 7), always the same : my box is not recognized by command lines.
I can only flash using the stock ROM usingUSB burning tools.
Maybe I have to do this but I'm afraid doing some wrong things :

You need to install adb universal drivers

If Netflix 4K is working with this box, it will be the perfect cheap box for me.

[Dicentim]

Hi,
I managed to flash the KM9 Rom, and the autroframerate worked great but as I had no support for the voice remote I tried to flash again but this time I couldn't enter the command lines.
The KM3 device is well detected in USB burning tool, but not when I try the "fasboot devices" command line.
And I get an error when I try to enter "update bulkcmd fastboot".
So without using the command lines the box has bootloop during the first boot.
Fortunately I was able toreflash the stock firmware back.

I'll try tomorrow using another computer, or wait for a zip update of your ROM.

The error I get in command line :

C:\soft>update bulkcmd fastboot
AmlUsbBulkCmd = fastboot rettemp = 1 buffer = fastboot
Read status usbReadFile len=512,ret=-5 error_msg=libusb0-dll:err [submit_async] submitting request failed, win error: Un pÚriphÚrique attachÚ au systÞme ne fonctionne pas correctement.

return len=-1, buffer=
ERR: AmlUsbBulkCmd failed!

[Dicentim]

Thanks B2oba17 !
One last question, the main difference between the KM9 Pro and KM3 is the double wifi band for the KM3.
With this ROM will the wifi of the KM3 remains as efficient as the stock ROM?
Thanks a lot.
Cheers from Reunion Island.

It would be so good if you can patch Netflix 4K, this box should be a great alternative to Nvidia Shield for third of the price.

Hi b2oba17, welcome back !
Unfortuantely nobody managed to inject the keys to get Netflix 4K working on KM3, although we strictly followed your procedure.
We all got the same DiskInitial error, any further information please ? Thanks

I have not been able to get Amazon Prime to work. Sometimes if there is a preview before the show/movie that will play. Once my show/movie starts I might get audio & and black screen or just a black screen. I have tried several versions of the Amazon Prime off of Aptoid TV & non have worked. I don't understand how it works for some & not others. Any help is appciated.

KM3 Ver - 905300090316

Two of the many veersion that I have tried.

4.14.3-googleplay-armv7a
4.8.69-googleplay-armv7a

I found one for the Xiaomi Mi Box that I had download quite a few months ago that is working. I am curios to know what the difference is though?
