intelmorino I think you need to trigger "recovery" mode on the box again. This will trigger the factory u-boot to search for boot scripts and read them, and the important bit - store/overwrite the file-search routines. If you've simply switched the SD card the stored config will be set to look for CE/Legacy files, hence LE bootscripts are not automatically found and read. It's also interesting to see the file rename approach, I wouldn't have thought it would work (but then I don't test with Legacy images or CE at all). Also good to hear the A95XF3 dtb is okay.. I've submitted it upstream and it should be merged for Linux 5.18.
No dice. I took your comment on board and reflashed the stock Android image. Then reflashed the LE image and set up the dtb in uEnv.ini. Then tried to recover from Android using the "update" app but that failed and took me to the boot menu. Powered down and repowered with the toothpick method, but that took me into a boot loop. So I think I've excluded the possibility that I've missed something.
Hi Chewitt, some feedback on these January 2022 postings regarding a95x F3 Air. I never did get it to boot then, but since you reinstated the chainload boot into the boot scripts, this device now boots fine. I used a u-boot.bin from a previous Libreelec compilation and changed the extension to "ext".
