It will not work, OTAs require the stock recovery. Since you hace TWRP there is also a chance that it might have mounted your system before, so your system image isn't vanilla anymore and the OTA will fail to apply. First try flashing stock recovery from here (search for the version you currently have, which is -33) https://forum.xda-developers.com/g5-plus/how-to/firmwares-moto-g5-plus-t3593160 and then apply the ota. Since the firmware you're on is quite outdated, you'll probably have a couple more OTAs on the way.
Now if that doesn't work, you'll need to back up everything you have (apps and data) and flash system, oem and recovery, and then apply the ota updates, then restore your data.
Long story short, didn't backup before everything, hard bricked with an OTA, recovered only by blankflashing and flashing the feb2018 gpt.bin (NPJS25.93-14-15) and then since I don't have the ROM for NPJS25.93-14-15, I flashed everything else from NPJS25.93-14-13.
Phone is working. Got TWRP in there, made a backup this time. Installing Magisk softbricks it, but that I'm trying to solve in another thread. Got the backup before trying to install Magisk anyways so I don't make it harder on myself to OTA.
I'd like to be able to do OTA updates, mainly due to the KRACK vulnerability that was solved with NPJS25.93-14-15.
The issue is: how do I get the phone back to the same version on everything? Afaik, I can't downgrade the gpt.bin to NPJS25.93-14-13 (when I try, I get the security downgrade error leading to a remote failure), which means I would have to bring everything to NPJS25.93-14-15 straight up? Can I do that without hardbricking again? As in, flash back the recovery from NPJS25.93-14-13 (the only thing that is not stock is twrp) and straight up do the update ignoring the fact that my gpt.bin is already from the version I will be updating to?
TL, DR Can a phone with NPJS25.93-14-15 gpt.bin and everything else NPJS25.93-14-13 make the OTA update to NPJS25.93-14-15? Can one downgrade gpt.bin somehow?
Did you find a solution for your problem? Maybe it's possible to flash all patched files manually to bring all to NPJS25.93-14-15??
1)If you revert back to NPJS25.93-14-13 fully, you should be okay to use the OTA update to NPJS25.93-14-15. This only will work as NPJS25.93-14-13 is the firmware directly preceding the Feb 2018 update. Using a firmware older than this may well cause a hard brick when you try to OTA update. However, you must fully re-flash or revert to a completely clean stock firmware build - no TWRP, no root etc. Unlocked bootloader does not matter. Easiest way would be to fastboot flash the stock NPJS25.93-14-13 ROM
2)Yeah, generally you cannot downgrade GPT or bootloaders - this is the underlying cause of bricks, as flashing old firmware results in applying old OTA updates, which corrupt your bootloader. However, in this case you're applying an OTA update that is as newer or newer than your existing system, so you should be okay.
3) You could in theory flash the Feb 2018 stock ROM - this is not been fully verified but some users have been able to successfully flash it. Verify this first before flashing: https://forum.xda-developers.com/showpost.php?p=75961872&postcount=716
4)Rooting on stock Nougat on our devices requires a custom kernel. Attempts to root on the stock Motorola Nougat kernel appears to trip anti-rooting protections and so causes the boot failures you've mentioned. You'll have to flash the stock firmware, apply the update, then flash/boot TWRP, then flash ElementalX (or another custom kernel) then magisk.
Holy cow @echo92, thanks so much for the detailed answer! I'll give this a try and update here with results.
Firmware Finder shows there's a new update available for my BTV-W09. It's B355 dated 06/05/18. It's a small OTA, only 190mb. Has anybody installed it? Does anybody know what's in it?
Firmware Finder provides the changelog. It has the June security patches.
No netflix hd update? ****!
How install? I don't remember. [emoji28]. Thanks in advance.

Anyone have any luck applying this update with TWRP recovery? Looks like it is going to require a flash back to stock to apply?
I was only able to install it with stock. Even then, it had to be the full install, not the OTA update. That install locks the bootloader and unroots; so I then had to re-unlock, which of course wipes the entire device, and then restore from a Google and Titanium backup. Not sure updating is worth the pain. really.
My rooted tab is now threatening to install this update when I reboot. Does anybody remember how to stop a firmware update when it wants to update on reboot?
I don't think there's much to worry about as if you're rooted with TWRP, it'll just reboot into TWRP and wait for you to manually apply it, if you can find it on the file system.
I'm currently trying to apply B356 which was recently released. This minor update contains the July 2018 Google security patches. The last time I did this from B351, this is what I did:
Via TWRP, Installed the 2 full OTA zip files for B352 downloaded with firmwarefinder. This replaced TWRP with the stock recovery but did not wipe my data.
Rebooted, and applied B353 via the normal OTA through settings. This installed the B353 full package (2.52GB).
Reinstalled TWRP with fastboot (twrp_BTV-W09_5_greatslon.img)
Booted to TWRP & installed Magisk
Re-enabled the 5GHz wifi radio
However, this doesn't seem to be working with B356 thus far. Installing the Firmwarefinder zip files failed (at least update.zip did, I didn't try the other two) so I installed the FF B352 images mentioned above. However, applying the stock OTA through settings wants to install 3 patches (B353, June 18, July 18) of size 786MB. They downloaded successfully but then it fails to apply during the reboot.
Anyone else have any luck? What did you wind up doing?
Thanks!
Every time I've applied an update, I ended up locking the bootloader and then having the phone wiped when I unlock the bootloader. I'd love to find a way to update without locking the bootloader. If you find a way to that with this update, please let post how you did it!
Hi my Moto G4 Plus(Stock Android 6.0.1, xt1642) don't gets updates anymore. I had Custom Roms installed. But restored the Stock Rom via TWRP. But Motorola published Android 8.1.0 a while ago.
Now my question: How to install the 8.1.0 Update?
Thanks in advance

Which route are you wanting to use, TWRP or flashing fastboot stock firmware?
N.B. Back up your device in TWRP and keep the backup off your device before proceeding with either method.
1)Using TWRP to update your device (with an Oreo TWRP flashable) will not fully update your device - it will only update system, kernel and modem. However, this approach might be useful if you wish to downgrade back to Marshmallow, and retains TWRP. Your kernel and root will be replaced. https://forum.xda-developers.com/moto-g4-plus/development/rom-oreo-8-1-0-soak-test-t3873367 for the Oreo TWRP flashable firmware. You will not be eligible for OTA updates.
2)Using the fastboot flash firmware means a more complete update, so possibly fewer issues and greater stability, however you should not downgrade safely after formally updating. For the Oreo fastboot firmware: https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138 You do not have to lock your bootloader (omit fastboot oem lock begin and the fastboot oem lock commands), and if you so choose, you could try to keep your data by omitting fastboot erase userdata. However, in case of instability, you may have to factory reset your device. TWRP, root and any modifications will be overwritten.
My UK XT1642 G4 Plus is running on OPJ28.111-22 with an EMEA baseband without issue. I hope this is the same case for yours.
