[HowTo] solve power on u-boot bug in NEXBOX MXQ PRO (s905)

Quote from sYCO

Oh, *****, okay. I have the Nexbox MXQ Pro 4K
and I thought that uboot fix is for both boxes,
because the thread opener was talking about
a Nexbox MXQ Pro, too.

If you past me remote control power button ir code - I recompile uBoot with MXQ Pro power button remote code.

And yet, on your current firmware, the indicator LEDs work correctly (Blue - on, red - off)?

You can flash my uBoot or firmware as a test. Should work, but I'm not sure about the power button MXQ Pro, if I throw here the code of the power button on the MXQ Pro, then I'll add it to uBoot.

Hello everybody! I'm glad to inform, I fixed uBoot:

1. Turns on and off from the home remote with the native "Power" button (Android / AlexELEC / LibreELEC)
2. The LEDs-indicators (were "confused" in places) are fixed: the blue LED is on, the red LED is off.

Firmware(NEXBOX-A95X 8189etv 8g1g 160812 with uboot fix) and uBoot separately can be taken here: MEGA

This is great. Thanks. I originally used elbuit solution and flashed your firmware as a replacement.

I have a Nexbox A95X S905 1G

I'm not sure why but on my box after the Nexbox logo it doesn't actually load Android but hangs on a black screen. However I tend to replace Android with Libreelec and by using the toothpick method I can first boot to SD and then used the installtointernal to copy Libreelec to Nand. Libreelec is working as an internal installation, I can use the remote to power up the box and the LED colours are correct.

What file and how you flash?

I flash with USB Burning tool and file NEXBOX-A95X_8189etv_8g1g_160812_uBootFix.img All was excellent, the android was loaded without problems.

Hi. Thanks for your work.

At first I tried Burn Card Maker v2.0.2 and wrote to a microSD card leaving the options at default; erase bootloader (yes), erase flash (yes - erase in normal), reboot (yes). Using the toothpick method I tried to load from the microSD but something went wrong and my box would only show a black screen, it wouldn't even boot to the splash screen Nexbox.

I then connected my box to my computer with a male-male USB cable and used the USB burning tool v2.0.5.15-build7 along with the file you uploaded, NEXBOX-A95X_8189etv_8g1g_160812_uBootFix.img. This unbricked my box and showed the Nexbox splash screen but wouldn't load Android. This was enough for me to use the toothpick method to load Libreelec from an SD card and then install onto Nand.

I guess the failure to load Android is unique to me because of the failed initial installation. My advice for anyone else having trouble is to use the USB burning tool to install the firmware upgrade.

Thanks again djspawn. I appreciate what you've done.

Hi djspawn,

I've tried with my Nexbox A95 (without X) S905Box. Your version didn't work for it:

- toothpick mothod is not working (box always boot into andriod)

- remote control is not compatible

This means for me: there is really a difference between A95 and A95X (both S905 version).

So I stay on elbuit's version. The only minor thing here is the reverted LED.

Hi

I have A95x 1/8G S905 (without X). Guess this fix is just for this model. GREAT!

Im using LibreElec in Nand.

I'm about change firmware but have questions - just like before - Is it possible to just exchange the uboot without the need of a new installation LE?

If not possible - how to make complete copy/backup of LE with outside path (not enought place in nand to save backup) and then after changing firmware (new with uboot fix) how to restore it to have just exactly the same LE configured just like before?

in libreelec setting is option for backup/restore

Yes, you're right. But you can't choose path and I alwas get information - not enough space for backup.

in system/settings/file manager add custom samba folder then you will be able to choose it in backup/restore

Thanks, will try

I add samba folder. When making backup I can choose it but when I clik ok nothing happened. Backup isn't making.

It works only when choosing internal storage.

Mate just insert a USB Stick and back up to that.

Do whatever and once you're back to a fresh install LE just restore from previous backup with the USB Stick inserted.

This thread is not meant for back up issues.

Is it possible to only flash the uboot?

I have a box here ready, only the power on bug is a real pitty.

I would like to flash only the uboot and keep the Libreelec install on the nand intact.

I'm tring to flash the u-boot for my device using linux.

I have downloaded the last firmware and extracted it using this guide

now I have

$ ls 
aml_sdc_burn.ini    
aml_upgrade_package.img  
bootloader.VERIFY  
boot.VERIFY  
logo.PARTITION  
manifest.xml  
platform.conf       
recovery.VERIFY   
system.VERIFY
aml_sdc_burn.UBOOT  
bootloader.PARTITION
boot.PARTITION
DDR.USB
logo.VERIFY
meson1.dtb
recovery.PARTITION
system.PARTITION
UBOOT.USB

now I need to "dd" one file to /dev/something.

But...

• Wich file I need to flash uboot aml_sdc_burn.UBOOT ? boot.PARTITION? bootloader.PARTITION?

I have probably another box coz it's name is only MXQ PRO, and I have Android firmware with proper uboot - power button is ok but if I boot Libreelec from SD my remote is not working and I'm not able to power-on the box.

I was redirected here from another topic and would like to understand is it possible to fix problem with LibreELEC on SD by replacing uboot on internal storage?

hi thx to elbuit for the power on fix. i add boot logo and elbuit power on fix to this rom
