Have you modified the system in any way, like installing Magisk?
What happens if you turn the phone off and connect it to your PC via USB while keeping Volume Down pressed? It should boot into fastbokt mode so you can change the active slot with fastboot --set-active=[a|b]. The current slot is written on top of the screeb.
• Upgrade to iodéOS 4.0 based on Android 13 / LineageOS 20
○ Improved blocking settings. You can now choose ‘Standard’ blocking (ads, trackers, malwares, etc) or ‘Reinforced’ blocking (same objective but more extensive), and then select additional categories.
○ The ‘Porn’ category has been extended to a wider ‘Sensitive content’ one, that also includes fake news, gambling, drugs, piracy, torrent…, with mainly child protection in mind.
○ The ‘Extreme’ category has been removed, as it is now part of the reinforced blocking.
○ Improved blocking lists. We merge several acknowledged and up-to-date sources, and have diversified our sources to produce more complete lists. The standard list has however been reduced a bit, to avoid as much as possible interference with apps expected behavior.
• Added a new network location provider: Local NLP Backend. It is an improved version of the DéjàVu NLP backend which was already available in iodéOS. Like DéjàVu, it builds a local database connecting localizations learned from other NLP backends and apps using GPS, and mobile antennas/Wifi; but also has an active mode (not preselected) that can trigger GPS requests. To configure it: Settings → System → microG → Location modules
• LineageOS synchronized with January security patch included
• All apps updated
• New devices support: Pixel 3, 6, 6a
I recently received my new FP4 and I’m still considering which custom ROM to install. iodé is currently my favored solution, but not 100% sure yet. What I’d like to do: just install iodéOS , try it out, install some apps that are important for me and check whether they run smoothly. If not, then I’d consider trying another custom ROM as well.
In that context, my question is: after flashing iodéOS, how easy is it to set back the FP4 to its original state? Or at least flash a different custom ROM? Or is there any" permanent" change introduced to the FP4 when installing iodé?
Of course, I’m aware that I need to the backup all the data and that I risk bricking the phone if something goes wrong during the process. My question is more about: is there some principle limitation to be expected, even if all the steps are executed correctly?
I would like to try iode and running my FP4 currently with the latest version of calyxos. Can I just install the iode os or do I have to return to stock rom first? Any other things to consider? I just really dont want to brick my phone. Thank you all for advice!
or with my instaructions, which are already actual:
Two important things
be sure to remove calyx avb_custom_key before flashing iodèOS fastboot erase avb_custom_key
before re-locking bootloader, be sure that:
check if bootloader unlock ability is possible =>fastboot flashing get_unlock_ability
→ (bootloader) get_unlock_ability: 1
==> if you get 1 then you can re-lock
==> if you get 0 do not lock bootloader
a good starting point for questions in case of problems is the iodé matrix room:
