After installing this version Vim_Nougat_Root_170612 my device does not delete the emmc anymore, I tried all the procedures described on the site, I turned on the device by holding the power button together with the function button and then I pressed the breviemnte reset, but I could not.
Do you have serial console access to u-boot? You could erase eMMC
Serial console is a must have for such developers board.
I do not have, how should I proceed to use another version? This nougat version has many bugs, I would like to go back to the original version.
I’ve tried this method but the system does not go into update mode at all. I press the buttons indicated to do the update mode but nothing happens, I tried the ‘M’ option but nothing happened.
You can try to type the adb command when you enter the system.
$ adb shell
$ reboot update
OK. Everything went fine thanks for the suggestion, this procedure is much easier than trying to press several buttons at the same time.
