Is this installation tutorial by munchy still relevant? (Invidious Mirror) this will be my first time installing a Custom Rom so if this tutorial is now outdated i'd love to be sent an updated tutorial if you have one.
YouTube tutorials for this kind of stuff are usually always shitty. I suggest against following any of them.
I heard the LineageOS Tutorial is outdated and doesn't work and that I should use the XDA Tutorial, but I find the XDA "tutorial" expects you to know how to do most of the steps, where as I do not. The video I found seemed to me to be the best combination of the 2. I'd love some advice on this.
The official wiki install guide is absolutely fine except for the need to install this copy partition zip mentioned in the XDA post. Just follow the wiki instructions but flash that zip before the LineageOS zip. The method is the same, once you flash that zip go back to the TWRP main menu and do the LineageOS one, no reboot necessary between those two.
and can the Amazon Prime Exclusive version of the phone be used for LineageOS install or is it incompatible? Figured it'd be nice to save a few bucks if possible.
No. They are not bootloader unlockable. Get standard unlocked retail or Android One.
Do you know if Google Fi will be adding any new phones to their collection by the end of the year?
By the end of the year? The Pixel 4 for sure. Then there are rumors of a mid-range Pixels.
You've got a pretty good list of compatible phones: https://fi.google.com/compatibility . You can't find one that is black and it's good enough for you?
How about SuperBlack?
Yes, it is. I used it myself when unlocking and installing lineage on my own Moto X4 about two months ago.
I heard the LineageOS Tutorial is outdated
It's not outdated, but they're generic steps, not specialized for each separate device, in other words, it is quite useless.
I should use the XDA Tutorial
Yes, and you're right that it isn't very newbie friendly. The munchy video tutorial you posted follows the XDA tutorial, but makes it a bit more easily understandable.
can the Amazon Prime Exclusive version of the phone be used for LineageOS install
I'm not sure, but there IS some info on this at the XDA forums. Keep reading.
I have the Moto X4 (XT1900-7) with LineageOS installed and I'm very happy with it. I do recommend reading the XDA forums a lot, understand the A/B slots, partition scheme, and just have a general idea of all the steps before you actually take them. I followed munchy's tutorial with the XDA tutorial opened next to it. Also, make sure not to skip any steps, a lot of people forget to install the firmware to the B slot (the copy partitions zip from post 2 on XDA forums) and they run into trouble later on.
This phone is pretty stable, it's pretty hard to completely brick it, however, a month ago the lineage updater would/could cause your phone to soft brick. (Meaning, after downloading and installing an update from within lineageos, the phone screen would go off, and never turn back on again) This looks and feels like a hard brick, but isn't, and can be fixed by following this thread.
It was this one... It now lists at $140, but I bought it when it was $120.
