Just seen this before going to bed... Not a G6 owner as it's too expensive for me ATM (and also because the G3 still gets the job done for me), but I came here to thank you anyway. Wish you good luck with your new development, and hope it becomes a BIG hit like your previous releases for the G3 and G5! :cowboy: Keep the good work up, xpirt! :good:

updated faq #1 with a note.

twrp can't mount system when /data is encrypted. in order to decrypt data you have to format data using the button called "format data" (note: it's different from advanced wipe data!). after that you can flash fulmics.

for first time, my advice is: format data with the proper button, then go in advanced wipe and wipe system, data, dalvik, cache, internal storage too and then install fulmics rom.
this has to be done only the first time.

did it exactly this way.(format data, confirmed "yes"...twrp formats to ext4, wiped system, data, dalvik, cache, internal storage) ..still bootlooping...flashing from sd card...coming another custom rom (resurrection-remix) ...can this be the cause for the loops?

At last!!! Fulmics for G6. Awesome!!!! Working great. Got one question/reguest tho. Is it possible to enable WiFi Calling, as in put WiFi Calling in Call Settings list and a WiFi Calling tile in quick settings? I switched to Fulmics from stock rooted V10H, which is P4P Polish rom, and it has the above enabled. My carrier supports WiFi Calling, but there is no settings enabled for it in Fulmics :/.

At last!
Before flashing it I need to ask something. What should I do prior to flashing this ROM? Only rooting is necessary or something else either? How can I root, can someone provide me an step-by-step instruction how to do it? And the last thing - is it possible to transfer .obb games files to memory card (something similar to FolderMount app)?
Thanks for any help :)!

It's not "wipe" data the requirement, but to "format" It in order to remove encryption.

Thanks for this, finally G6 is usable! With all that tweaks even xposed is not needed. Although I miss little thing.

Can you add "Screen Off" to "Longpress Home" actions? If it is simple and not so much bothering you. If not, thanks anyway :)

Does Qualcomm DAC high-performance work on the UK version that was shipped with no DAC? Stupid question maybe?!?

Wasn't sure whether this was hardware change or locked in the software and your brilliant brains managed to unlock it.

    the rom is still active and will be updated in case of any issues, therefore the thread will stay opened.

    as for the re-base on oreo update, I didn't even have time to work on my current device (S9), so for the G6 it will take even more time till I look into it.

    that's due to my exams and my limited time as usual. you'll understand that by working on the rom I neither graduate nor make a living out of it -- it's just a hobby.

    who wants latest base and security patch can obviously revert to stock and enjoy oreo (till - if it will happen - next update).
