Flash Android to eMMC

Hello,

erased my eMMC and flashed another OS on it. Now I want to go back to Android but it doesn’t work.

I used following documentation and tried it on Windows 10: https://wiki.radxa.com/Zero/install/eMMC_Android9

The flash-all.bat disconnects the device and I had to reconnect and switch to fastbootmode again. Then the script goes further. When the script is done the OS should be flashed. But in my case it only shows the first splash screen again and again. I tried it so many times and with so many things but always the same result.
Now im at a point where im not be able to turn the Radxa Zero in Fastboot mode. The bootloader.bin and the factory-loader.bin are not working anymore for it.

What am I doing wrong?
Is there a IMG file for Android to just flash with BalenaEtcher?

i have the exactly same problem. i tried so many different things from the wiki guide, and no result.
I feel like my problem is connected to Uboot. It seems like it doesnt boot at all. Screen is just black.

Same issue here. I tried In windows and Ubuntu. No Luck. I gave up and switched to Lineage OS (Used AML Flash Tool in Ubuntu to flash LineageOS)

Coreelec and Ubuntu also work fine. Their Android Image instructions are non working

Do you know if Manjaro on SD Card boots with LineageOS in eMMC?

My goal is to run Manjaro and this only works with Android installed in the eMMC.

Haven’t tried Manjaro, not a fan of Arch Based stuff.

I just reflashed Stock Android to emmc, stuck at “MBOX” logo.

Tried in both Windows and Ubuntu, same result. They need to fix this

Heres an error i got in Ubuntu

/tmp/TemporaryFile-lvYJfl: Unimplemented ext2 library function while setting up superblock
/usr/lib/android-sdk/platform-tools/mke2fs failed with status 1
mke2fs failed: 1
error: Cannot generate image for userdata

******** Did you mean to fastboot format this ext4 partition?

Android stuck at boot screen

Yes I stuck on the first boot screen too. I tried it so many times and always the same result.

Im stopping, i dont want to burn out the emmc. I switched to Coreelec. I erased with radxa-erase-emmc.bin. Plugged into Ubuntu and flashed with etcher. K*di works perfectly on the Zero

I GOT IT !!!

Install ADB/Fastboot tools (just google it) and add them Both to PATH in Windows 10 (It has to be added to path to work) (add both adb.exe and fastboot.exe to PATH)

Step 1: Hold USB Boot button and Use RZ Boot Helper to flash radxa-zero-erase-emmc.bin (this will erase the emmc so back up first if necessary)

Step 2: Open RZ Boot Helper and also Open Flash-All.bat, then Replug in while holding USB Button and flash bootloader.img from the Android image folder, the moment it stops flashing it it’ll reboot into Fastboot mode and the Flash-All.bat script will start.

Step 3: The Flash-All.bat script will STOP early and your device will disconnect, just unplug it and plug it back in. The script will finish. And board will boot into Android 9…

I already had my monitor plugged in. The MBOX logo takes a few, be patient

No I don’t get it. The first half of the “flash-all.bat” runs fine. But when I replug the device I have to press the USB Boot button and run the “bootloader.bin” from the android folder again. Then the script goes further. But the writing for near everything fails. How exactly do you reconnect the device? Just replug the USB cable or what you have done?

All I did was run the flashall.bat when it disconnected I just unplugged and plugged back in. I didn’t hold down the USB button at the point where it disconnects

Holding down the USB button puts it in Maskrom Mode. You want it in fastboot mode not Maskrom

When I unplug and replug it, it wants to boot the half flashed OS and it shows the first splashscreen again and again. To come in fastboot mode again I have to replug it with the USB button and execute the bootloader again.

Did I forgot something to execute that my Radxa Zero doesn’t comes into Fastboot mode again in the middle of the flash-all script?

Can you try modify the flash-all.bat and delete fastboot reboot-bootloader line that’s above ping command? I flashed Android with flash-all.sh in Linux before without problem so this is the difference between those 2 files.

hi, have your rom setting wifi?

Hello Radxa,
in my case the flash-all.bat does not run till the end. It always seems to fail at
fastboot flash system system.img

I tried to erase fastboot reboot-bootloader. That did not change anything. Re-plugging in also did not change anything in the script.
