X96 Max+ and ceemmc -x failure

me 2 i’m very confused does it matter dat it is een b grade brand ? chipset is al the same wright? on the bottum i see TT TV BOX android player model:X88PRO X3 RAM:4GB ROM:32GB

What is booting if you remove all USB and uSD?

Here is a technique I have found to help boot when my emmc gives me errors:

  1. Boot USB or SD card to CE
  2. Choose “reboot to nand/emmc” from power menu
  3. Once android starts, reboot.

It should then boot to emmc properly.

the tv lights up nothing on screen.

i’m not seeing reboot to nand or emmc or simmelar. Under Power Options i see: power off system, customshutdown timer, suspend, reboot, restart kodi.

my X88 has 32G when android was working i saw 28GB something in the partioning went wrong ? or is this normal ?

I don’t know what is wrong on your box. The internal memory should still work as you still able to boot something. I guess best is to recover your box by a vendor Android image.

finaly it let me instal coreelec after i try to instal a rom with usb buring tool,
but it’s not booting after instaling en restarting tis is what i did :

CoreELEC:~ # ceemmc -x

You can now power off the device, remove the used boot media (SD or USB) and
power on again to boot the device from eMMC!

So CE only on eMMC. Does it boot now? And when you run the ceemmc -vx now what is the output?

no it is not booting same as before, CoreELEC:~ # ceemmc -vx

Thank you, I will test it later here if something is broken on the tool.

Thank you, please let me know.

I just tested a single install on one of my devices with current 9.2.2 and it is working fine:

CoreELEC:~ # ceemmc -vx

Also this is working here:

I don’t know why it should not work on your device. What happening if installing in dual boot mode?

What does this mean? You install in single mode so only CE is on eMMC, Android get deleted.
How you where running ceemmc again? Botted from uSD/USB?

I wonder if it has something to do with the bootloader?

I was playing with my A95X Max trying to run from eMMC in single CE boot mode.

The process of installation seemed to go fine, apart from one warning message that read Warning: Could not find ‘dtbo’ partition!.

The 64Gb eMMC was seen and all the formatting and transfer of data looked good.

After the process was complete, I removed the original boot sourse and restarted but all that happened was that the vfd shows the word boot and stuck there with no further progress.

The one thing that I noticed that was different with the boot process was that the A95X Logo that normally appears as the first thing on screen when starting up was no longer being shown.

Putting the boot source back in the box enabled the original boot again.

When i ran the ceemmc process again it was interesting to see that it said ‘No CoreELEC installation found on eMMC’ which was unexpected.

So perhaps just a case of some boxes not capable of eMMC installation because of not having the necessary bootloader present?

This is warning only because some vendor name it different.
What happen if install in dual boot mode? Maybe there is something different in bootloader, yes. I don’t know because I have no such hardware -> unsupported by CE.

In dual boot mode, android boots but when switching to CE just a blank screen unless the original boot media is inserted.

In my case I’m not surprised that it didn’t work because I know that it’s been a struggle for people to provide custom Android ROM’s for this box because of the bootloader, so perhaps Bubble’s box has a similar kind of issue.

I boot directly from an internal SSD in my box anyway, which works well for me, so the use of the ceemmc tool was more of a what if rather than a desire but might indicate the kind of direction that the issue may be coming from.

Any of you have a chance to get a bootloader log? It have to be a UART log, dmesg is not enough.
When you do not want to open the device this is may a alternative: CoreELEC Team SDIO Debug Board

i’m goning to try dual boot, yes i boot from usb, to use the ceemmc command.
How i get ceemmc get running again , is by try to install(alm buring tool )with rom version x96p3 air because it has identical specs so it is my best bed. i can’t find original rom for this box

aml usb buringtool ease flash & bootloader that helped so de ceemc tool could clean install CE.

A have a FTDI adaptor and soldering and open up tis box is no problem, but how do i create a log do you have a guide ?

Just use putty and record every print on booting. Maybe there is some information why it is not working. When you post pictures of your opened box we can search the 4-pin UART header. Sometimes there is also the mark with RX/TX.

I fond 3 holes named DBUG with labeling i connected the FTDI adaptor(ft2332rl) GND>GND TX>RX RX>TX . In putty tick serial com3 try diffrent bauterate en other serial settings, check drivers comports also linux and windows10 get no output, even if i boot from CE usb NO OUTPUT.

i ordered a new adaptor to rule out if its broken FTDI adaptor.
