Custom ROM installation
AshThe instructions for installation are just like any other recovery ROM.
**Please Read Everything**
Download the recovery images mentioned below from Lineage OS
https://download.lineageos.org/devices/bramble/builds
https://download.lineageos.org/devices/redfin/builds
• boot.img
• dtbo.img
• vendor_boot.img
Or extract the ROM zip with a payload dumper and flash the same images from there. Either way is fine.
Next boot the phone into bootloader with buttons or CMD;
adb reboot bootloader
Once in the bootloader flash the recovery images from earlier;
fastboot flash boot boot.img
fastboot flash dtbo dtbo.img
fastboot flash vendor_boot vendor_boot.img
Then use the volume buttons to highlight recovery mode and press the power button to select and the phone will reboot to recovery.
format data/factory reset >>
apply update >>
apply from ADB >>
adb sideload rom.zip
Let it complete and reboot system ✅
( see below )
**If you have flashed a Gapps build or do not want Gapps then you can skip this part**
If you want Gapps, when prompted to reboot to recovery to install additional packages after the ROM install select yes and when in recovery follow the same steps above but for the gapps.zip and again let it complete and format data again just for good measure and then reboot system ✅
Notes:
• Do not type out rom.zip or gapps.zip, drag and drop the respective files.
• The CMD sideload may stop at 47%, this is normal and the ROM has still installed successfully.
• If you get a signature verification error with Lineage recovery images just select yes.
• When using Local Update it may appear stuck at finalising installation package, but it will start moving after 5 minutes or so, let it do its thing. Once it reaches 20% it will get faster and faster and then jump straight to 100% and be ready for reboot. This is basically OTA update but the user downloads the OTA package manually instead of the updater doing it for them. This method retains gapps that have been manually installed on vanilla builds.
