Hallo, I have an older tab (ga10h A23). There is fel-sdboot.sunxi installed on the SD card and the tab seems to boot from it. $ lsusb Bus 006 Device 003: ID 1f3a:efe8 Onda (unverified) V972 tablet in flashing mode i:/tmp/sunxi-tools-master# /usr/local/bin/sunxi-fel ver AWUSBFEX soc=00001650(A23) 00000001 ver=0001 44 08 scratchpad=00007e00 00000000 00000000 i:/tmp/sunxi-tools-master# /usr/local/bin/sunxi-fel spiflash-info ERROR: Allwinner USB FEL device not found! Whats going wrong? Is it possible to list partitions on the internal flash with sunxi-fel (or another tool)? and write a file on a partition? regards Andre bg: I tried to replace the recovery partition on the tab (trwp). This going wrong. If turned on then the logo is displayed. After that the display is black. can't switch to recovery/boot-mode. Now I am looking for a way to restore the original. sunxi-fel seems a way. The partition was: # ls -l /dev/block/by-name/ lrwxrwxrwx root root 2023-03-27 08:29 UDISK -> /dev/block/nandj lrwxrwxrwx root root 2023-03-27 08:29 boot -> /dev/block/nandc lrwxrwxrwx root root 2023-03-27 08:29 boot-resource -> /dev/block/nanda lrwxrwxrwx root root 2023-03-27 08:29 cache -> /dev/block/nandh lrwxrwxrwx root root 2023-03-27 08:29 data -> /dev/block/nande lrwxrwxrwx root root 2023-03-27 08:29 databk -> /dev/block/nandi lrwxrwxrwx root root 2023-03-27 08:29 env -> /dev/block/nandb lrwxrwxrwx root root 2023-03-27 08:29 misc -> /dev/block/nandf lrwxrwxrwx root root 2023-03-27 08:29 recovery -> /dev/block/nandg lrwxrwxrwx root root 2023-03-27 08:29 system -> /dev/block/nandd -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
