Yes, it does

What issues are you experiencing? Is it failing to connect, or falling to stay connected, or slow speeds? What router do you have and do you have Google Cast enabled?

I'm curious, as I'm on the NPJS25.93-14-13 build and am connected to a TP link W8960n router and do not appear to have WiFi issues. The router is set to WPA2 AES (no TKIP) broadcasting on 2.4 GHz (802.11bgn)

The router is ZTE ZXV10 W300 series.
Don't have Google cast.

Thanks, and if you reboot the router, does the connection still drop out after a while? Do you then have to reconnect to the router, or does it refuse to connect?

Can i ask if this occurs on any other WiFi networks?

Also, is your router set to WPA2 AES or TKIP (or both), are you on 2.4 GHz or 5 GHz, and do you have a fixed frequency channel for the router WiFi?

You can only reflash September 2017 firmware if you unlock your bootloader (which voids any remaining warranty and wipes your device in the process).

It is set to WPA-PSK.
The Chanel is 11.
And i don't know how to figure if it is 2.4 ir 5 GHz.
When i reboot router, it connected and after a while it drops, by saying "connected to wifi, not to internet".
On other networks, does the same.
Sometimes it works, but at very low speed.

Flashed on a XT1644 US retail model, using the method that doesn't erase user data. Flashed the ElementalX after that and then flash-rooted with Magisk. Replaced the boot logo with my own.
All good.

Hello everyone,
I have a G4 plus XT 1642 Reteu stock NPJS25.93-14-10, TWRP SHREPS, Kernel ElementalX-G4-1.04, SU root.
I simply removed the root, reflashed boot.img stock with TWRP and recovery.img stock with fastboot and then installed the patch.zip : I am now with the build NPJS25.93-14-13.
After I reinstall the ElementalX kernel and the SU with TWRP Shreps. No problem, no data loss. Thank you.

i just applied this update, i dont want to have any issue again. cause i want to root it, so, i have to flash elementalx kernel to be able to root? i wanto to flash SU cause severalmonths ago i used magisk and i think the battery was drained. i just have to flash latest versions of elementalx and supersu or what?

Yes, for rooting on Moto G4/Plus devices, flashing a custom kernel is still the straightforward way to get root. Attempting to root the stock Motorola kernel appears to result in soft bootloops, requiring either a flash of the custom kernel or a TWRP backup/reflash of the stock ROM to recover from. I did try attempting to flash a magisk modified stock kernel (a patched kernel), but my device failed to boot, either due to incorrect patching or the /data partition being formatted as f2fs. Besides, custom kernels give you more options to tune your device.

Bear in mind Chainfire appears to have retired from SuperSU development, I do not know if another developer has taken up SuperSU duties.

Regardless for rooting, the general procedure is:
1)Flash/boot TWRP. Back up device and additionally make a duplicate stock kernel (boot partition) backup.
2)Flash ElementalX v1.04 or v2.0.
3)Flash SuperSU or magisk. Wipe cache/Dalvik.
4)Reboot.
5)Any issues, revert to the backup you made in 1)

Magisk 15.3 is running well on my device with NPJS25.93-14-13 and ElementalX v2.0 and I'm not noticing any major battery drain, your experience may vary.

Hello, yes, you only have to flash the new version of ElmentalX and the SU with TWRP to root your phone.

i have a question, can i reflash this update without issues? i took my moto to a friend of a friend so he check out an issue with the phone's mic (i don't have a service center nearby) and i think that guy performed a factory reset, now i cant enable wifi among other issues, i'm really sad and dissapointed right now.

    Some observations about this patch:

    a)36.2 MB in size, carrying the December 2017 security patch as noted above with a final build of NPJS25.93-14-13/3. md5: 28d24a02c7e7caecf4be102a6059074f Though it's the 1st December 2017 update, I'm not sure if this update has the KRACK patches built in (as they were covered by the 6th November 2017 patch) - depends on when Motorola got the patch. Apologies for misleading anyone.
    b)From the updater script, requires NPJS25.93-14-10 already on your device to flash.
    Code:
    Package expects build thumbprint of 7.0/NPJS25.93-14-13/3:user/release-keys or 7.0/NPJS25.93-14-10/10:user/release-keys
    c)Looks to be carrying updates for some apps/services, such as BellTVWidget and OmegaPttMX.
    d)As helpfully noted by RenePaul99, updates the bootloader to B1:07 (with a build date of 2017-11-07) from B1:06 in NPJS25.93-14-10. This may result in the blankflash we have at https://forum.xda-developers.com/moto-g4-plus/how-to/moto-g4-plus-hardbrick-solved-guide-t3657761 failing to work if this OTA update is applied - it may check and only work on B1:06 and earlier bootloaders (and no, generally you can't downgrade bootloaders) I'm not certain of this, though I dislike seeing devices bricked and the only resolution being an expensive motherboard replacement. So crucially, if you've updated your device to this OTA update, be very careful if you decide to flash older Motorola stock ROMs (e.g. after flashing a custom ROM), as an OTA update could hard brick your device, and the current blankflash may not work in rescuing your device. The safest way to revert, if you updated to this stock patch level, would be to use your TWRP backup or wait for the NPJS25.93-14-13 fastboot ROM to be 'obtained' (leaked) from Motorola.

    EDIT - 17/01/2018 - I've seen one possible rescue with the latest blankflash we have from a user updated to the December 2017 B1:07 bootloader. Though it suggests the blankflash is still working, be very careful regardless.

    As generally with OTA updates, they only will flash successfully onto a device with a clean stock system, stock recovery and stock kernel. Unlocked bootloader status doesn't appear to matter.

    Of course, if you're rooted, then the above aren't true; I was running a XT1642 with TWRP, ElementalX and magisk 13.3, so the OTA update is a no-go. One straightforward way to restore my device to a OTA friendly state was to re-flash the NPJS25.93-14-10 stock ROM (which we have here: https://forum.xda-developers.com/moto-g4-plus/how-to/stock-rom-npjs25-93-14-4-march-1-t3608138)

    The following flashing commands I used should not affect your data and return your device to an OTA friendly state, but as always back up your data just in case. You may be able to use fewer commands but I prefer to flash all these partitions (you probably want to do things properly with the core firmware running your device!) As far as I know, system, OEM, boot, recovery and logo partitions need to be stock at the very least. GPT/bootloader/modem you could omit if you're sure they are the same patch level as NPJS25.93-14-10 (bootloader should be B1:06 and modem should be ending in 62.01R), if you're not sure, I'd flash them too to ensure all your firmware is of the same patch level. Don't mix and match patch levels when it comes to OTA updates... Oh, and check that you have plenty of time, you don't want to rush firmware flashes.

    Code:
    fastboot flash partition gpt.bin
    fastboot flash bootloader bootloader.img
    fastboot flash logo logo.bin
    fastboot flash boot boot.img
    fastboot flash recovery recovery.img
    fastboot flash dsp adspso.bin
    fastboot flash oem oem.img
    fastboot flash system system.img_sparsechunk.0
    fastboot flash system system.img_sparsechunk.1
    fastboot flash system system.img_sparsechunk.2
    fastboot flash system system.img_sparsechunk.3
    fastboot flash system system.img_sparsechunk.4
    fastboot flash system system.img_sparsechunk.5
    fastboot flash system system.img_sparsechunk.6
    fastboot flash system system.img_sparsechunk.7
    fastboot flash modem NON-HLOS.bin
    fastboot erase modemst1
    fastboot erase modemst2
    fastboot flash fsg fsg.mbn
    fastboot erase cache
    fastboot reboot

    After manually flashing each command (copy and paste is your friend, though nothing to stop you using a script), my device rebooted to system (complaining of bad key or N/A on the bootloader warning screen, that's normal). Rebooted to stock recovery (with the Android on its back and the no command), then held the power button before pressing and releasing the volume up key, then releasing the power button. Took a few tries before getting into the recovery menu. (as explained here: https://forum.xda-developers.com/moto-g4-plus/help/command-stock-recovery-xt1642-t3484616 )

    As before, flashed the OTA update without issue from the SD card/internal storage (though had to mount /system as the recovery complained it couldn't mount internal or external storage, after mounting the 'apply update from SD card' worked and loaded up internal storage...), wiped cache after installation and rebooted.

    Now I'm running NPJS25.93-14-13 and still have all my data :) Not rooted or having TWRP on, but I might see how I get on with this new build. Initial impressions are that it's fast and stable, though early days yet. As for the camera, photos and video with the rear camera appear to work okay with version 6.0.86.7 of the Moto camera app, what problems have been mentioned with the camera?

    I'm from Mexico too, I received the OTA today too

    ---------- Post added at 10:37 PM ---------- Previous post was at 09:52 PM ----------

    It seems that this update will also update the bootloader to B1:07(in the September patch Rom, it was B1:06)
