But my phone is rooted, so why should it keep saying that TWRP needs to be updated.
No I didn’t, but when I looked for it on the Motorola site I couldn’t find it and via Google I landed on a number of dubious sites and my browser started screaming warnings, so I didn’t proceed. I don’t think it will be a solution though, because I can’t seem to install anything or even wipe anything, but if you could tell me where I can find the official Motorola flash software I’ll give that a try.
Still struggeling here. I bought a refurbished Samsung from E to support their privacy cause, so I’m not dersperate, but I’m really pissed off, that I can’t get the moto G4 to work anymore. I’m no computer wizzard, but not entirely dim either. I feel I’tried everything, so if someone has any idea that could help me, please let me know.
Still no succes. and still hoping that someone can help me 
Does your device show up here on the motorola site …they have a chat support link there you can ask for their official software to flash the stock ROM.
Idea: Start from scratch and reinstall everything.
→ Moto G 4G/LTE Stock Firmware (XT1039/40/42/45) via Fastboot
→ /e/ ROM latest dev build for peregrine dev (nougat)
alternatively: → Flashable StockROM via TWRP
TeamWin - TWRP
How can I uninstall or remove TWRP from my device?
For the vast majority of devices, you don’t actually remove TWRP to get back to the stock recovery. Installing a different recovery is your only real option. Simply install whatever recovery that you want and that will overwrite or replace TWRP. …
First I wrongly flashed falcon, and get error 7
I try the peregrine, since CPU MSM8926 seems to be it, but error 7 persist.
So I try your stock.zip file link, and it worked.
But when I try peregrine again (the /e/ nougat), it gets error 7 too.
I’m doing the wipe dalvik, cache, system, and formatting data before flash it.
If anyone had this problem and get it solved, please share =)
Thanks for your idea @archje
