Hi. This is my first post in this forum. I had this problem, the phone always started in TWRP Mode after updating by OTA update, I should NOT have updated it this way, but I have done it still. XD
To fix it, try this:

TWRP Method:

1- Go into TWRP -> Go to Advanced -> Go to Terminal:
Enter

2- Please make a backup first of these files in SD card:
Code:
cp /dev/block/platform/soc.0/7824900.sdhci/by-name/mota /sdcard/mota2
cp /dev/zero of=/dev/block/platform/soc.0/7824900.sdhci/by-name/misc /sdcard/misc2
3- Type this exactly:
Code:
dd if=/dev/zero of=/dev/block/platform/soc.0/7824900.sdhci/by-name/mota
HIT ENTER
Code:
dd if=/dev/zero of=/dev/block/platform/soc.0/7824900.sdhci/by-name/misc
HIT ENTER

4- Restart the phone.

Recommendations: Freeze or change name of the Motorola Update App "com.motorola.ccc.ota" ( /system/priv-app/3c_ota/3c_ota.apk ) to solve the continuous update message.

Work fine in my:
MOTO G4 XT1621 Athene
Android version: 7.0
Kernel: 3.10.84-ElementalX-G4-1.04
Firmware version: NPJ25.93-14-8.1

Sorry for my bad writing. Correct me if necessary.

Hi,
Thank you very much. It worked on my Moto G4 XT1621, but there is an error in the cp command (backup): "cp /dev/zero of=/dev/block/platform/soc.0/7824900.sdhci/by-name/misc /sdcard/misc2" should be "cp /dev/block/platform/soc.0/7824900.sdhci/by-name/misc /sdcard/misc2"

When I ran the dd command I had an no space error, but I ran the second dd command anyways (it also had the same error) but after the restart the phone boot directly to android and not to TWRP

Thanks again.
David.

Both dd commands worked for my XT 1643.I deleted 3c it's file before doing this. I get normal booting after trying lot of tricks.

There is no mota file in my phone's /by-name folder. Instead there is the following:
boot
cache
expdb
flashinfo
frp
keystone
lk
logo
metadata
nvdata
nvram
oemkeystore
otp
para
proinfo
protect1
protect2
recovery
seccfg
secro
system
tee1
tee2
userdata

And the path is slightly different: /dev/block/platform/mtk-msdc.0/11230000.msdc0/by-name

My phone is a Moto C Plus xt1723 2GB ram/16GB memory dual sim

Which file do i go with?

Sorry for bringing this up in 2019, but I got stuck in recovery bootloop when upgrading Stock Nougat to Oreo (OPJ28.111-12).

Even when flashing via fastboot adb, it did only boot by pressing START button on fastboot mode, after flashing any ROM, or after any reboot.

Your method worked perfectly in my XT1640, thank you !!
