After waiting over a year for the Nougat update (still nothing) and almost a year for a security patch (nothing since Dec 2016), and now knowing Moto will probably never patch the KRACK wpa2 bug, I'm officially done with Motorola and their carelessness with our security.
My questions:
I assume if I load a custom ROM, I will be able to stay up to date with patches and new Android versions? True?
Which one do you all recommend?
Edit: A solution which can pass Safetynet is HIGHLY preferred
I don't need anything fancy, I just want everything to work properly like the stock ROM, but be able to stay up to date
I don't even need root, as in the past I've had some apps stop working if I was rooted, although with systemless root, that night not be a problem anymore. I guess it would be nice to be able to root if desired, but have it as an option only.
Edit- probably should have mentioned I'm on the US Moto X Pure Edition (XT1575)
Thanks for any help.

First off it's a 2 year old phone. That's a normal end of update cycle. Second the 7.0 update is out for the 1575 but for some reason only Sprint Sims seem to have gotten it so far. It's still coming to your phone. Custom roms are nice for updates to a point but safety net still doesn't like them if I recall properly. I switched from the pure to a Moto Z play and have loved it. About to get the October security patch and they're already working on Oreo for it. The pure was the last phone before Lenovo took over. There were issues with the hand off but they seem to have it together mostly now.
@xantanion, thanks for your post. I could argue with you about whether the phone was updated on a timely basis over the last 2 years, but I don't want to get into that right now.
Good point about safetynet. If I'm going to go custom ROM, I'd like to be able to pass safetynet, whether by using Magisk, not rooting, using a custom kernel, whatever options are available/necessary.
With this in mind, any suggestions for a solution?
Not getting security patches (my current situation) is not acceptable.
I'd like to squeeze another year out of this phone before replacing. Thanks for any suggestions

I'd switch to Dirty unicorns. I retired this phone a couple of months ago, but they maintain it regularly, and release monthly security patches. As for safety net, magisk works great. Since on Android 7.0 + even an unlocked bootloader trips safety net, then you actually NEED magisk to patch that and then pass safety net. DU is an unrooted ROM but just flash magisk afterwords.

Lineage OS 14.1 (based on nougat 7.1.2) gets security updates monthly. It's close to vanilla android and doesn't come with all the bells and whistles of unicorns or aicp. This is good for those happy with the stock android features like myself. I don't need custom themes and crazy config options. Never needed a custom kernel. Battery and performance is exceptional as is.
https://download.lineageos.org/clark
Rooting with Magisk 14 will pass safetynet. I use android pay daily with no problems.
https://forum.xda-developers.com/attachment.php?attachmentid=4302781&d=1508010356
I run with a fairly minimal OpenGApps 7.1 arm64 aroma installation. I use the aroma installer and pretty much only check the boxes for a few apps to be pre installed. If I really need something I can grab it from the play store or apk mirror. My base config for OpenGApps aroma is here: https://drive.google.com/drive/folders/0B2lKWOIH0bTqMEQ1cmo2QjlydDA?usp=sharing

If the new stock 7.0 nougat release is what you're after you can get a twrp backup here you can restore from. Keep in mind this is 7.0 not 7.1.2 and security patch up to only September 2017. This will be the last update to the Moto X Pure/Style. So no further security patches.
I tried stock 7.0 for a few days but went back to Lineage OS. I missed the long press on icons to get actions menu that isn't in 7.0 (among other things).

Thanks, @Spencervb256, for the recommendation and comments on Safetynet and security patches.
Double thanks, @ptn107, for the helpful recommendations and files. I really appreciate you sharing that info.
If you'll continue to put up with my ignorance, do I correctly understand how to restore to stock if I choose to do so later as listed below. I'm still on MPHS24.49-18-16. I didn't update to 7.0.
1) According to this thread, the MotoX Pure can only be returned to the stock firmware it was running before switching to a custom ROM, or to a newer version. You cannot go back to an earlier version.
2) There isn't a firmware .zip available for 24.49-18-16, so according to this post, you flash the 24.49-18-8 .zip (which IS available) and then sideload the .zip from @annoyingduck to update to 18-16 to get back to where you started.
3) Alternately, since the file for Nougat 7.0 is available, I could also update to 7.0, then load a custom ROM, and later return to 7.0 using the available file.
Am I understanding this process correctly?
Thanks in advance for your help.

I'm not extremely knowledgeable on the whole returning to stock unfortunately...but if you're currently on 6.0, almost all the custom roms are compatible with that firmware, and only a SELECT FEW (such as a lineage os test build) are compatible with the newer 7.0 stock firmware. Paging @dzidexx for a better explanation

Thanks again, @Spencervb256.
So you're saying that the Android version of my custom rom has to match the version of the stock rom that I'm coming from? No mixing marshmallow and nougat?
Also, if I stay on marshmallow and want to return to stock and unroot, I wonder if I can just flash the available nougat firmware and restore the stock recovery. Maybe @dzidexx can help with that question, too.
Wish I was more skilled in all this. Thanks for the help.

No haha it's hard to explain. But until about a month ago, no custom roms could be flashed if users were running stock 7.0 from Moto. Now there are a couple builds of roms which can be flashed over stock 7.0, with no bootloops. This is because Motorola upgraded the modem firmware in stock 7.0, so the custom roms did not work with it.
You can 100% mix the two, so if you are in stock 6.0, you can install any rom you like, as they are made to work with the 6.0 firmware. Even though they are nougat roms.
When stock 7.0 was released, people had issues with installing custom roms over that, because of the modem upgrade, but now there are a couple builds that will install over this firmware and not result in a bootloop.
I will try and find a few links for you which can explain some things, this is all from my mediocre memory haha
If that confused you even more then just stay tuned, I'll send you a pm soon with links to some reading in different threads which explain it much better than I can!
@Spencervb256, I think I understand you. Most of the custom ROMs, whether MM or N, use the stock radios released with MM. When Moto updated to N, they also changed the cellular radio, so the custom ROMs don't work properly unless they are updated to be compatible with it.
So then, if I stay on MM, I can use any custom ROM, if I would've updated, I'd be limited to the few ROMs that were updated.

My rule of thumb is simply wait for the official supported OS version. This means everything (including modem) will work - the community will then hack and modify from there.

That's exactly it! You nailed it. Explained it better than I could, so yeah, you got it!!
Hello, could someone explain me why magisk is necessary for custom roms for our device? When bootloader boots custom kernel it should boot rest of the system without any problems but it bootloops even before bootanimation
I also need custom ROM without Magisk. Is any Oreo custom ROM supports SuperSU?
RR-O ROM+Gapps goes to bootloop without Magisk and RR-O ROM+(Gapps)+SuperSU goes to Bootloader mode.
RR-O ROM+Gapps+Velocity Kernel boots & works, but RR-O ROM+Gapps+Velocity Kernel+SuperSU goes to Bootloader mode.
So anyone can please help for any Oreo custom ROM + Gapps + any rooting app (SuperSU, Lineage addonSU, phh's SuperUser).

Have you figured it out yet? If not here, we go...
A Custom ROM is to give you 100% control, it's the point, and to have 100% control, the phone needs to be rooted to access the system.
In Linux, 'Root' means, what the Admin is in Windows...
Kind of pointless to install a custom rom, with limited control, of course you can root a stock rom too.

Not necessarily. Custom roms may have up to date security patches vs out of date stock roms on older phones. And custom roms may have extra functionality especially on bare bones stock rom like the MiA1.

Yes of course all the 'Bells & Whistles' I didn't mention... But that's not the reason for rooting, which is what the OP asked...
Anyhow Custom ROMS give us many things, but it's about being in Control...
Cheers
I seem to remember reading something some weeks ago that Samsung did something in their latest few updates for the S8+ that made it impossible to root them... is that true?
I'm running a SM-G955F - DTM here... and I'd rather keep it rooted. I'm using magisk to root my devices.
Any insights for me?
AFAIK, as long as if you have twrp installed, you can update to whatever you want.
you then can:
make a full backup with TWRP, and Samsung can't do anything against you just restoring the full backup (with the old update and root)
just flash whatever (custom)ROM you want.
You already are rooted, so OTAs aren't a thing for you. I don't know if there even exists a twrp flashable stock ROM, but why don't you just switch to a custom rom (with the newest updates installed)?
Honestly, the only custom rom i know of is lineage (nee cyanogenmod), and at least on my old S5 I found that the fingerprint reader does not work on cyanogenmod. also, anything that checks safetynet does not work either.

LieangeOS isn't even available for our device (infact it is, but unusable).
The custom roms available right now are all stock touchwiz roms with slight modifications (most of them aren't even necessary, thx to aroma).
Look over to a thread like the one from Renovate ICE, most of the time roms like these are based on the newest sources from Samsung with the newest security patch level. It has root (Magisk or SuperSu) included and also passes safetyNet.
As I said in the post above, you always can make a full twrp Backup, try a ROM like Renovate Ice and if you don't like it, just go back to your stock ROM in minutes. :fingers-crossed:
hey ! i want to flash fastboot rom , currently im on custom rom. please tell me what is the latest firmware for indian varrient & link also of firmware.
If you're on a custom rom, and that rom is an Oreo rom, you will need to apply the persist fix to make sure you don't have any problems when moving to stock (e.g. lost IMEI, no Volte, no 4G, etc). For the guide here:
https://forum.xda-developers.com/g5-plus/how-to/fix-persist-resolve-imei0-explanation-t3825147
If you know what you're doing, here's a link to NPNS25.137-92-14, the latest for the retin channel.
https://mirrors.lolinet.com/firmwar...ubsidy-DEFAULT_regulatory-DEFAULT_CFC.xml.zip
Edit: Also, do you really need the fastboot roms? Unless you're looking to lock your bootloader, maybe you'll be fine with the TWRP flashable stock roms - available for both Nougat and Oreo (soak test, not yet official).

Comes down to what you want to do with your phone. If you want to keep root access, then you may as well stick with the TWRP flashables, as the full stock firmware will not install OTAs if you are rooted. Quite often the TWRP flashable builds will be available sooner than a lot of people receive OTAs through official channels. That is, once one person receives the OTA and shares it with me, I build the next flashable zip normally within a couple of days (I'm the maintainer). The modifications are minimal - just disabling dm-verity and forced encryption (the latest Oreo flashables built on the Aroma installer make that optional).
If you want to lock the bootloader for any reason (e.g. in order to sell your phone, or you want to ensure the highest level of security) then you only really have one choice - full fastboot stock.
Anyway, you can have a read in the two threads for Nougat and Oreo:
[Nougat][Stock][Rom] TWRP Flashable Stock Builds
[Oreo][Stock][Rom] TWRP Flashable Stock Builds
I was using Xtended Custom ROM (Oreo) with a rooted device and then i was just trying to unroot the phone and flashing Stock ROM but it didnt worked so i rolled back to Custom ROM and then my fingerprint sensors are not getting detected in any Oreo ROM.. please help!
If you really want to stay on an Oreo custom rom, you have to downgrade to stock nougat first. Easiest way to do that is use the latest nougat twrp flashable stock rom
https://forum.xda-developers.com/g5-plus/development/twrp-flashable-stock-builds-t3813351
Other option is to just go to a pie custom rom.
Edit - just remembered the is another thing you can flash that will just get back the fingerprint, but if you use NFC that won't be fixed. Maybe someone else has the link.
I got my fingerprint sensor back but lost VolTe now!

If u had nougat and the u flashed PE 9.0 then volte will have issues. PE moved to oreo base long time back. Its better u flash stock oreo first and then move to any Pie Rom. There are some guides around to get volte back might wanna look around. Did you not make a backup of the stock image?

Did you boot into stock nougat before flashing the custom Oreo rom? If not, it is probably necessary. (When you had -a at the end of that filename, I assume you mean aroma? If so, then that one applies a fix to your persist which is needed going back to stock nougat, so that's all good.)
If you did, then it may just be a case of needing to go onto stock Oreo then a pie custom rom. Some things about the stock nougat just don't work properly after being on Oreo...

Try clearing cache within twrp. You shouldn't take any OTAs from the twrp flashable. If it was the OTA for Oreo, then might be easier to do a wipe, as I can't remember where the OTA gets saved.
I'm assuming that your device is trying to go to recovery all the time as it knows the OTA is there to be installed.
Worst case, total clean flash and install again.

Two basic rules:
- Make a backup. Every time before you flash anything. Every time.
- You only can apply and install OTA updates when on a signed and unmodified fastboot firmware.
Twrp flashable ROMs have a lot of advantages but they are not unmodified.
Agree with @NZedPred: Make a full wipe and install
a) a fastboot firmware if you need to take OTA updates, these are found here:
https://mirrors.lolinet.com/firmware/moto/potter/official/RETAIL/
b) a twrp flashable ROM if you won't take OTA updates, these are found here: https://forum.xda-developers.com/g5...flashable-stock-builds-coming-t3830482/page68
