About:
LineageOS is a free, community built, aftermarket firmware distribution of Android 9 (Pie), which is designed to increase performance and reliability over stock Android for your device.
LineageOS is based on the Android Open Source Project with extra contributions from many people within the Android community. It can be used without any need to have any Google application installed. Linked below is a package that has come from another Android project that restore the Google parts. LineageOS does still include various hardware-specific code, which is also slowly being open-sourced anyway.
All the source code for LineageOS is available in the LineageOS Github repo. And if you would like to contribute to LineageOS, please visit out Gerrit Code Review. You can also view the Changelog for a full list of changes & features.​
Introduction:
This is the unofficial Lineage OS thread for the Motorola G7 Power, codename ocean.
We support all the T-Mobile, International, and Project Fi variants, as their bootloaders are unlockable, while we can't support the Verizon and AT&T variants, as their bootloaders are permanently locked.​

04. Flash your factory firmware image on slot_A
Hold power + Volume down untill you reach bootloader (fastboot mode)
In your extracted firmware folder open a terminal and flash your firmware files with these commands.
NOTE: This last step installs vendor.img to slot_b as well.
05. Use terminal to boot latest twrp.img "fastboot boot twrp.img"
06. While on Slot_A Flash copypartitions.zip (This step only needs to be completed Once only after updating from stock factory firmwares.)
07. While in TWRP choose Reboot > bootloader
08. Now you're ready for ROM Steps below
ROM - Installation:
01. Download the ROM, TWRP and GApps from the links above.

Thanks for the rom. Do you know if the Moto gestures work? Like chop twice for camera....
EDiT..
Yes moto actions are included in this ROM. Awesome job. Buttery smooth so far. Nice attentive display. LTE+ I see now in the status bar. No issues to report yet.
Just to root. Flashing magisk from twrp won't boot system. I had to back up the boot.emmc.win from twrp and use the install via patch boot method. Bam rooted on Lineage OS.
I'll report if any issues should arrive. So far Great ROM.
Make sure you fastboot flash your stock firmware first.

---

YES! I've been waiting for this since I bought the phone, and had almost given up all hope seeing the lack of activity in the forums for this device. While I'm far from an Android dev, I'll get to tinkering with the unofficial TWRP port and with this ROM during the weekend and will let you know how well it goes
Thank you!

---

Thank You , Awesome answered prayer overnight. As an inept tinkerer I typically brick phones or have days of migraines attempting this sort of upgrade but your guide may be almost idiot proof. Working for me at least, only snafu was flashing the ROM , I guess my phone wanted partitions mounted first as I got the " Not enough space in Data or System " error. Persistence a reread of guide and another prayer put me over the top. I went from soft-bricked to rooted linage in minutes. XDA rocks ! Peace

Does VoLTE work? If the camera, Bluetooth, and VoLTE work I'm installing it.

Everything works on my variant. Retail...Im not going back to stock.
So smooth no bloatware. An option in settings you can turn off all animations besides the settings in developer options. This phone flies with impressive battery life. The bugs are very minimal. Like i use LG tone Bluetooth headsets and when i get a text it takes 7 seconds to read out loud. On stock it was 2 seconds before my texts would be read. I noticed on you tube vance the 720 p streaming sometimes gives a slight second blur. Other than these two bugs. The rom is near prefect.

Works.
Been experimenting with it to see if the rom allows simple bypassing of the Metropcs sim lock. So far no luck. Keep in mind I dont have a working sim card for it, and am attempting to have a standard lte t-mobile sim work.
Also experiencing an issue with the screen colors going bonkers randomly, requiring restart (or two) to fix. Not sure if this is a device issue, a screw up during flashing, or a rom issue (keep in mind this was a phone only rarely messed with, not a daily driver).

Just fyi, there is no way at this time to bypass a sim network unlock simply by using another software.
Sim unlock is a Carrier Remote over the air network in which requires a program to unlock. (imei) Only carriers or sim unlock service's like on ebay can achieve this with a fee of course.. older phones which dont have an unlock app may have been able to sim unlock using a third party tool but that was ages ago.
Average sim unlock cost for newer devices $35 u s dollars. older phone's around $10 u s dollars.
Metro by T-Mobile unlocks for free after 180 days of service.
Hope one stops thinking sim unlock is free.
Buying a phone from a carrier will be sim locked automatically. Buying the same phone that can be bought in different regions and is not exclusive to any carrier will be sim UnLocked. Buy non- carrier branded phones in the future to avoid being stuck to one carrier. (Amazon,Ebay and BestBuy)

Is it possible to bring the stock firmware back via fastboot in case I face any problems with the ROM? Is the procedure ordinary?

---

weird colours
Mostly it works, but the screen behaves strangely...
The colours are messed up, it looks a bit like if it was using 16 colours, and there are some horizontal lines close to the top and to the bottom of the screen.
I've tried to take a screenshot, for showing you, but on the screenshot the colours are fine
I've tried also AOSP Pie, and there the colours are ok.
My device is XT1955-4 retail EU
Anyone else is experiencing my problems?
Can I help debug somehow?

---

The benefits of this rom I like:
No Bloatware
Fluid , fast and responsive
More data options on Metro by T-Mobile. I get HSDA+ and LTE+ always. Stock i hardly saw anything but LTE and HSDPA only.
Selinux off by default with init.d support.
Near Stock Pie experience.

Unfortunately, I dont have a color issue.
I use color changer pro for this phone because how dull the colors are. So my screen is great
I saw a color changer option in the settings you can tinker with to get your colors the way you like it.
(Under Live display)
I have mines set to sRGB
DPI set to 420. wink wink...

so I have to flash the rom and twrp to ramdisk

I can't install gapps says insufficient storage. When I check the size of the system partition it says 4mb.
Edit: I fixed this somehow so nvm

Hey!
So, I tried installing this, and I've encountered a roadblock. I think I've got all the steps from "Preparation for A/B Roms" category right, my issue appears when actually flashing the LOS zip file. When I'm on TWRP and I go ahead and try to Install the ZIP, it simply stops after "Done processing script file" (after both steps of Checking for Digest file... are complete) but actually there's nothing on the internal memory of the phone. This means that after rebooting, I only get a bootloop on the "bootloader unlocked" warning screen.
Some things to note:
I've copied all required files to the microSD card on my phone, and I'm trying to install everything from there.
I've been doing all the TWRP stuff from the CMD prompt in Windows using ADB because for some reason the touchscreen won't work on my phone while using the unofficial port of TWRP.
I've copied a log file from my console right after step 6 of the preparation, that is, flashing copy-partitions-payton.zip up to where I get stuck, in case this is helpful to help whoever wants to lend me a hand with this

The good thing is that I was able to recover the original system image from the lolinet file I downloaded, so my phone is fully functional and ready to give it another go hehe.
Any help will be more than welcome. I'll try giving it another go on my own during the weekend.

I had a snafu because i tried to install the rom using the TWRP already installed and I was rooted with xposed.
You must start from scratch before flashing. The OP's directions were spot on if you follow to the T.
The TWRP in the OP is important and I notice in TWRP im on slot _b.
Hope this helps ya..

Nope, in my case I had the phone fully stock before trying this. I did the whole preparation first anyway, removed my Google Account from the device and factory reset it, then flashed the downloaded factory firmware image as instructed in step 04 with the console commands in dogbin.

I'm using TWRP-ocean-test-1 from the thread OP linked. I can't use the exact one posted by the OP in that other thread since for some reason the touchscreen doesn't work with it.
By the way, how did you end up in slot_b on TWRP? Unless I'm missing something, in no step the OP says to change to that slot during the preparation or installation steps :/
--------------
Also, I just tried starting everything from scratch. Before going to bed last night, I reflashed the original factory image I downloaded from lolinet only to install WhatsApp and use the alarm. This morning, I re-did everything carefully and got logs at every stage, here they are:
Stage 1: These are steps 4 and 5 of the preparation. I removed my Google Account and factory reset the device, then I rebooted into fastboot and began entering the commands from the dogbin page. As far as I can tell, the console shows no errors at this stage.

Now I'm in TWRP, instead of using the interface on my phone, I used ADB Shell to flash copypartitions to gather the logs. Here I flash copy-partitions-payton.zip while on Slot_A as instructed (I checked by going to "Reboot" in TWRP, and it says "Current Slot: A" at the bottom, so I know I'm using the correct one). Here's where the first issues appear. I check the log in TWRP and it says at the top in red:
Code:
Could not mount /data and unable to find crypto footer.
Failed to mount '/data' (Invalid argument)
Unable to recreate /data/media folder.
Updating partition details...
Failed to mount '/data' (Invalid argument)
Full SELinux support is present.
Unable to mount /data/media/TWRP/.twrps
MTP Enabled
I proceed anyway, and install copy-partitions-payton.zip.

Then I go to Reboot > Bootloader in TWRP. I get a warning that no OS is installed, but I swipe to reboot anyway and proceed using the -w command in fastboot.

Here I still get some errors about metadata and some permissions denied, maybe some of these errors are the cause of my problems?
In any case, I keep on going and reboot to TWRP again using the Windows console.

Now in TWRP, I proceed to install the ROM zip + TWRP on Ramdisk as instructed in Step 3 of "ROM - Installation". Needless to say, the errors about /data are still present when TWRP boots up.

Now I go to Reboot > Recovery in TWRP. I still get a warning saying that no OS is installed, but I reboot anyway and I succesfully get into TWRP again. I try to install OpenGapps but I get an error 70 complaining that there's no enough space in System partition. If I reboot my phone to system, I get into a bootloop on the bootloader unlocked warning.
Thank you in advance to anyone willing to help me out! Surely I'm missing something trivial due to lack of experience. I've flashed many ROMS before, but this is my first time giving it a try since the A/B partition stuff was implemented :silly:

Okay i do recall i had to format data so i could mount all partions. The copy partitions zip has to be flashed in the twrp of the o.p
In regards to me being on slot_b. the copy partiitions zip accomplished that part. The rom is flashed on slot_b. The O. P TWRP is needed. You keep using the wrong TWRP.

Homie as soon as TWRP installed you gotta format data where you type "yes" and reboot recovery or you end up fubared in loops or worse. Follow steps exactly...
