Installation of new versions of LE-9 (with 4.18 kernel) in eMMC is possible in two variants.
- With preservation of regular u-boot-2015 (recommended option). Retains the ability to return to Android using the standard tools of firmware of the USB Burn Tool and etc.
- With the replacement of u-boot-2015 to u-boot-2018 (in this version all eMMC is used for LE operation and there is no possibility to use standard USB Burn Tool tools).
For installation on the first option.
- Start LE from external media.
- Check the operation of all the necessary functions in the new LE (I strongly recommend that you carefully perform this item, that would then not have to solve the issues of recovery to previous versions).
- If the new version is satisfied. To include in the LE access mode via SSH. Connect via SSH and run “/flash/create-mbr-le-2015.sh”. If there are no errors, run “/flash/install2emmc.sh”.
After these commands, the LE will be written to the eMMC and when the power is turned on without external media, the LE from the eMMC should start.
The second installation option (with the replacement of u-boot-2015 to u-boot-2018).
- Run from external media and perform a full scan, as in the first option.
- Connect the external media to the PC and rename the external media file " vim-2018-u-boot-emmc.img " to " u-boot-emmc.img."
- Start the system from external media and connect via SSH. To run the command “/flash/update-u-boot.sh”.
- To run the command “/flash/create-mbr-le-2018.sh”.
- To run the command “/flash/install2emmc.sh”.
In order to be able to revert to the current state of the system in eMMC, prior to all experiments with installing LE in eMMC, I strongly recommend making a full backup of the entire eMMC. To do this, you need to connect via SSH and run the command “/flash/ddbr-backup.sh”. This script will create a full compressed copy of the entire eMMC under “/storage/backup/ddbr”. In the future, you can run the script “/flash/ddbr-restore.sh” and it will restore the contents of the eMMC exactly to the state it was in when the copy was created (with the loader, settings, and other elements). Depending on the size and size of the eMMC, the copy creation process can take 5-30 minutes.
