These were the commands I ran (these are the ones [MENTION=2260280]doree[/MENTION] linked)

fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash modem NON-HLOS.bin
fastboot flash fsg fsg.mbn
fastboot erase modemst1
fastboot erase modemst2
fastboot flash bluetooth BTFM.bin
fastboot flash dsp adspso.bin
fastboot flash logo logo.bin
fastboot flash boot boot.img
fastboot flash recovery recovery.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 system system.img_sparsechunk.8
fastboot flash system system.img_sparsechunk.9
fastboot flash system system.img_sparsechunk.10
fastboot flash system system.img_sparsechunk.11
fastboot flash system system.img_sparsechunk.12
fastboot flash system system.img_sparsechunk.13
fastboot flash oem oem.img
fastboot erase cache
fastboot erase userdata
fastboot erase customize
fastboot erase clogo
fastboot erase ddr
fastboot reboot

Is it because the image is XT1635-02 instead XT1650-03?

EDIT:

I did flash it this way now anyway (I probably shouldn't have done this, sorry) but reboot failed now and moves directly to fastboot with the following error message:

Start Up Failed:

Your device didn't start up successfully.
Use the Software Repair Assistant on computer to repair your device.
Connect your device to your computer to get the Software Repair Assistant.

EDIT 2:

I tried ADDISON_NPNS25.137-24-1-4_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC with Android 7 now with the same effect. I guess I am missing something here?

PS: I absolutely appreciate your help and it's impressive how fast you answer. Thank you very much for this.
