Attention! Before installing firmware (rom) with support for dynamic partitions, read the following annotation/instructions:
1. The dynamic partition scheme differs from the standard scheme familiar to everyone, where there are only “System” and “Vendor” sections, the dynamic partition scheme consists of a common forming section “Super”, which is divided into “System”, “SystemEXT”, “Product”, “ ODM","Vendor".
2. Early firmware (roms) with the standart partitions of the "System" and "Vendor" sections are not compatible with firmware (roms) based on a dynamic scheme, do not try to flash over it even if the firmware is the same but of a different version.
3. Switching to a dynamic partition scheme entails the loss of all data! No old backups made on the basis of a standard partition scheme will help, setting up from scratch, be prepared for this.
4. For firmware (roms) built with a dynamic partition scheme, you need to install a special recovery that supports this scheme; old recovery will not work. In the case of my builds, this is Team Win 3.7.0 12-1 recovery based on kernel 4.9, which is presented here above on the channel.
5. For builds make with a dynamic partition scheme, only those kernels that support this very scheme are suitable (I think they will appear soon).
By installation:
1. Download recovery with support for dynamic partitions Team Win 3.7.0 12-1 based on kernel 4.9 (or possible analogues in the future).
2. Download the firmware (rom) built with dynamic partitions.
3. Back up personal data (photos, etc.) to any file storage device if necessary (I wrote about data loss above).
4. Install the recovery via "Fastboot" or through the menu of the old installed recovery, flash the img image from the recovery into the "Recovery" section.
Using “Fastboot” via a USB cable, we drop it into the root of the Linux, Windows, macOS system, open the terminal and execute “fastboot flash recovery recovery_name.img” (ignoring the quotes). You must first have all the necessary USB and ADB-Fastboot drivers installed.
5. Copy the downloaded firmware (rom) with dynamic partitions to the SD Card or internal phone memory.
6. Install using a new recovery (during the initial installation, some errors will appear, we ignore this since a normally new partition scheme has not yet been formed).
7. Without rebooting, wipe all partitions except USB-OTG, MicroSD, Internal Storage, and also execute Format Data (the one that asks for YES confirmation) and reboot into the system.
Firmware update with dynamic partitions (Retrofit Dynamic Partitions):
1. Reboot into recovery. (We have already performed the operations above, haven’t we?)
2. Flash the firmware (rom).
3. Reboot into the system.
Installing another firmware with dynamic partitions (Retrofit Dynamic Partitions):
1. Reboot into recovery.
2. Flash the firmware (rom).
3. We wipe all partitions except USB-OTG, MicroSD, Internal Storage, and also perform Format Data (the one that asks for YES confirmation).
4. Reboot into the system.
Return to standard partitions:
1. Reboot into recovery
2. Uncheck the “Settings > Unmount System before installing a ZIP” checkbox.
3. Go to Advanced > Unmap Super Devices.
4. Flash the firmware (rom) with a standard partition scheme.
5. We wipe all partitions except USB-OTG, MicroSD, Internal Storage, and also perform Format Data (the one that asks for YES confirmation).
6. Reboot into the system.
In a nutshell, what does this give us (Retrofit Dynamic Partitions):
Improved compatibility with GSI - Fans of MIUI and other similar branded firmware (roms) should rejoice, the sections are dynamic in which there are no fixed sizes, each size changes depending on needs automatically, of course within the main “Super” section (its volume).
