====================================
Upgrading LineageOS on OnePlus 7 Pro
====================================

.. warning::
   Always backup everything!!!

FIRST (update recovery img)
===========================

Update the recovery img with::

    fastboot flash boot_a ~vladan/Downloads/twrp-3.5.2_9-0-guacamole.img

The ``a`` in ``boot_a`` is the output of ``fastboot getvar current-slot`` because
the installation didn't have a recovery partition. The boot partition is used
for recovery, hence the command above. More info `here
<https://forum.xda-developers.com/t/no-such-partition.3733811/#post-75165281>`_.


.. warning::

    If this is not done in the first place, then `download twrp
    <https://eu.dl.twrp.me/guacamole/>`_ and boot it. I ran into a boot loop
    because I didn't do this in the first place and had to resort to TWRP.

To work around this issue, run::

    fastboot boot /home/vladan/Downloads/twrp-installer-3.5.2_9-0-guacamole.zip


Manually flash all partitions
=============================

.. code:: bash

    git clone https://github.com/vladan/payload_dumper.git

    python payload_dumper.py --diff payload.bin

    cd output
