I accidentally flashed a Retail US version on my Moto Z Retail EU, and now I am having a "bad key" at the Warning on boot up. Can someone provide me with a 7.1.1 or 7.0 link for Retail EU for the XT1650-03? It's for the normal Moto Z, not Play or Force. I NEED an Retail EU Boot as I flashed a wrong one and I cannot go back to 6.0.1 to fix it, so my Boot is broken until someone gives me a proper EU one for 7.0 or 7.1.

Thanks in advance!

Note: I am getting this when trying to flash the "XT1650-03_GRIFFIN_7.0_NPLS25.86-17-3-8_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC" files:

D:\MAIN FOLDER\Android\Moto Z\XT1650-03_GRIFFIN_7.0_NPLS25.86-17-3-8_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml\GRIFFIN_NPLS25.86-17-3-8_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml>fastboot flash boot boot.img
target reported max download size of 536870912 bytes
sending 'boot' (32768 KB)...
OKAY [ 0.078s]
writing 'boot'...
(bootloader) Image signed with key bad key
OKAY [ 0.805s]
finished. total time: 0.885s

So yeah, I need a boot image that isn't signed with a bad key for RETEU.

Alright, here. Make sure that you have ADB installed System-Wide on your PC, you can use ADB-AIO for that if you don't have ADB and Fastboot Tools installed yet.

Anyways, once you have that, download my .rar file (Yes, .rar, install WinRAR if you don't have it, I won't use .zip in order to compress much more and save space and download time for you), and then run the "Moto Z Automated Flash.bat" file, it should do everything for you, but make sure to READ what I wrote in it, when it asks you to "Press Enter", please READ everything carefully, I will NOT explain further here, everything that you need to know is described and explained to you while you use the "Moto Z Automated Flash.bat" file as a form of guide.

In case you wonder, it is 3.5GB large because it contains the STOCK 7.0 ROM for the Moto Z (that you will flash first), and then the 7.1.1 ROM from erfanoabdi that you will flash through TWRP. It also contains TWRP (which will be flashed during the guide/bat file) and a logo.bin that covers over the stupid "N/A" at bootup.

Hi,
I tried to unlock bootloader following instruction on Motorola website then my moto z play has "BAD KEY" and keep restarting with that message on the screen. I found and used your file but it didn't help my device out of the "BAD KEY". Please help. Thank you
