II have posted a question regarding Google's FRP on the LG K8 M200n (2017) in the correct forum:
https://forum.xda-developers.com/lg-k8/help/lg-k8-m200n-2017-frp-bypass-t3889757
I'm just spitballing here but I was wondering if an OS downgrade removes the installed Security Patch and reverts it back to a previous one or if the security patch is a permanent thing?
If it's removable I am wondering whether downgrading the K8 in the thread linked above would resolve the issues I am experiencing.
Cheers

If you're looking for a solutuon to FRP, that is actually not supposed to be discussed here at XDA, it's against the rules because that kind of information could be used by the wrong people for the wrong purposes.

OK, that's fine. I understand that but that doesn't answer this question. Is it possible to downgrade a device and remove the most recent Android Security Patch?

If the downgrade does not have those security patches or the same bootloader as what is currently on the device, they won't be there after you flash the downgrade, nothing should be there from before. Flashing firmware using the firmware flash tool designed for your device is virtually the same as wiping and reinstalling Windows, but it has to be a complete firmware downgrade, as in, nothing the same as the newer firmware.

Guys.......plz tell me how to flash android l final preview on n5 safely my n5 is rooted and running slimkat rom i have few questions regarding this...?
since my phone's bootloader is already being unlocked is it safe to flash factory image directly......?
im running slimkat rom does it cause any problem in flashing the factory image of final preview android l
thank you,
Regards
Flashing a factory image shouldn't even require a bootloader unlock , as long as it isn't a downgraded version, so yes from my experience with my RAZR at least that shouldn't be a problem, are you flashing complete stock ROM or just restoring system using twrp?
Might want to try that website.

It's an https://
Sorry I can't post outside links yet
Does that answer your question at all?

Yes. You need a unlocked bootloader to flash factory images.

Hello, apologies if this sounds like a newbie question but I'm currently on apc8 firmware on my galaxy s7 and when I click into software update in the settings it says that the current software I have is up to date even though there have been 3 or 4 new software releases since apc8? When android nougat comes out will I be able to update my phone to that or would my phone have to be running the latest software (the September patch) to upgrade?
Also when I try to back up my phone via smart switch it freezes at 81% when it is backing up documents and won't go any further. Not sure if anyone else has had this problem before but could shed some light on the issue.
Thanks for any help

Not rooted. I've found the firmware for my region and model but the phone still isn't backing up through smart switch and I don't want to flash a firmware with odin without having it backed up

Hey guys! So I have a few questions about the oneplus one here, I'm checking for a friend and I always had a nexus where matching firmware doesn't really matter much. So here they are.
1) What happens if you have the wrong firmware for a rom? Softbrick? Hardbrick? Nothing at all?
2) For a Nougat rom, what firmware do you use? Since this phone hasn't got an official firmware update for Nougat yet.
3) Is there a special recovery here on XDA that can flash all roms? (there was one for the oneplus two) or is TWRP good for all roms?
What confuses me the most about oneplus devices is how the firmware works different from most Android devices. Thanks guys!

Thanks! So it's not as important as it seems? I notice some roms here on XDA specifically say to have the newest firmware, or a certain version. The rom is still expected to boot? And what's the worst case scenario? A soft brick that can be easily fixed with TWRP or something worse? Thanks for the reply! Like I said, I'm coming from a Nexus 6 where none of this firmware stuff really applies :angel:

Yes the rom is a still expected to boot,though,the recommended frimware is to be used so as to avoid any bugs.
However,some roms do require the recommended frimware in order to boot but I don't think even if flash any rom which needs recommended frimware will take you in any kind of brick condition as when you flash a rom on incompatible frimware you'll see error in Twrp,if so happens you just need to have recommended frimware in your storage and flash it then flash the rom again and you'll not face any errors.
Good luck!

1. If you are using TWRP, nothing will happens. Because when you flash a ROM, TWRP will comparing your phone model with build.prop on the targeted ROM. Because based on my experience, somehow i download LineageOS for d802 and flash it to my bacon. TWRP gives an error and didn't flash any firmware. I don't know about CWM or other recovery
2. I'm using Lineage OS. It's pretty good so far. No bug or whatever
3. TWRP is good for all ROM. i think any recovery will do

Settings about phone. Software info. What's the base band and such...
From my understanding they can't patch the root method or at least have not. Yet. You should be good to go

If you have updated to Android 8.0 you CANNOT downgrade to 7.0. The bootloader is updated.

You can't root 8.0. Downgrade with your bootloader revision is possible with the same revision combination firmware. But it's a rest rom. So only option is to immediately flash part cyborg
Just for downgrading to 7.0 stock no. You cannot

You can't. You can port an already existing firmware from one device to work on a different device if the two devices have the exact same hardware, but you can't just "create" your own firmware.
