[Moto G7 Plus Questions & Answers] KtownJeff:
Why is it important not to have the copy-partitions.zip installed?

Ok so the copy partitons zip is only supposed to be installed when you install the first custom rom coming from original stock..... because it breaks the chain for OTA from motorola.... If you root stock and flash recovery only Its not necessary.... so that way when OTA comes it will move to the B partition the way that it was intended to.....but the boot-loader is unlocked now both slots start with a boot-loader, bootloader_a and bootloader_b.. .and the on board preboot chip will trip the first flag that communicates with stock flashed boot image which also holds the recovery and the kernel... even if its backed up stock.img with magisk, it will break the next flag on the device along with the custom logo.bin.... now the custom logo if it is cloned with a moto signature official it wont matter and the only one Im aware is logo.bin for the TMOBILE REVVLY variant.... when you boot not flash the stock boot.img it bypasses the security chain until reboot.... I've flashed b slot on accident and then booted several GSI and other lake Roms and at some point ill notice on the bootloader screen that maybe i have April 2020 when Im running July 2020 version....which is headache to fix and i booted to b slot flash stock as normal let boot to the setup wizard then reverse to a and do it again because it brings it back together... now the mapping for the AB partition with duel slots t is standard for all ARM64 AB devices Bootloader a and b Boot a and b Radio a and b which is (firmeware) slot Vendor a and b System	a and b....

the reason why I wrote it the way that I did was because I tried everything to OTA back and this was the only way it worked for me.... and trust me I stayed up for weeks trying to break it or fix it....I finally I came across a moto g6 thread where some one relocked there bootloader and didnt have the oem unlock set and they couldnt do anything to unlock it again using fastboot because the switch was grey out on developer options which means they couldnt root to fix..., I believe it was Sd_shadow that recommended trying to boot the boot.img like how we boot the twrp.img because it bypasses the security flag... well my first attempt it didn't work which led me to the mismatched boot-loaders and I kept at it and by process of elimination and fully learning the way these partitions communicate..... which is totally backwards from the way it used to be... If u leave data then flash back stock, the boot-loader thinks its fresh but finds its not......so boot-loop... tried it cussed and tried again and screamed but now its automatic. for me because of trial and error... I've been at this a few years now and I'm learning something new all the time and most of time when people don't post is because they either don't know or don't wanna give wrong info or maybe nobody showed them. There kinda is an unwritten bylaw at XDA (tough love)... you gotta learn by experience that way when get an opportunity to help or find a new way it makes it worth the stress

That is why I wrote it the way I did step by step in the easiest way possible because of my experiences and headaches...If it don't work you didn't follow directions.... Now I'm gonna tell you I re-locked my bootloader too and was not able to flash back ota don't even try its a waste of time because the only way to get that flag back is to re ball a chipset, or replace the motherboard, or buy a new phone....

Sorry, but this is the most complicate way for an OTA I have ever red. You could sum up these steps to "flash the stock firmware". In the end the result is the same. But it's much easier.

Our device is unbreakable... trust me I've tried to and still haven't managed to Qualcomm brick it.... test point is the only way to get it to EDL mode and i plan on taking my screen off tonight just to see if I can..... and write another essay because some ass hole from Germany thinks he know everthing
