[Google Pixel 8 Pro] leveleyed:
I have a few issues. I'm guessing it would be better to make one post and number them instead of several a separate post for each.

FULL DEVICE BACKUP: Is there any way to copy files from the root level of my P8P to my PC, or from one P8P to another P8P (both rooted)? I've tried via cmd.exe adb pull, but get either adb: error: failed to stat remote object or adb: warning: stat failed for path <path>: Permission denied or adb: warning: skipping special file, so then I tried adb root pull but get adbd cannot run as root in production builds. I want to be able to copy all settings forall apps AND the system/OS, just in case I run into any problems and need the data later on.

REASON: google device setup SUCKS! and after doing it like 3 times, factory resetting after each time because, every time, it missed restoring a bunch of files/apps/settings from my old P8P (the defective one one I need to return), and because I only have like a day left before I need to ship it to Google lest I get charged full retail for it (and I'm pretty broke rn), I want to make a full backup of EVERYTHING on it before I have to wipe and return it, because with as poorly as the setup of the replacement P8P is going, I know I'll be kicking myself if I don't have a full backup copy of all the files on the old P8P.

NOVA LAUNCHER: I was convinced by someone on here to use Nova Luncher when I first set up my P8P. I tried restoring from a backup I made. on the replacement P8P. It doesn't add any of the home screen shortcuts I made from Chrome webpages, or any of the folders or the shortcuts they contained for literally dozens of Google Home Automation Routine shortcuts I made to control various devices/lighting in my home. Is there any way I could restore these by copying app data for Nova Launcher from one P8P to the other, or perhaps via restoring from a Swift Backup of the Nova Launcher app?

WIFI AND MOBILE DATA LOSING INTERNET CONNECTION (I seem to have resolved this one for the time being, but will add it here anyway in case the problem returns. Mainly just wondering if anyone else has had this issue, and what you found that ultimately resolved it for you): After installing all the apps from the Play Store, rebooting, downloading and installing Magisk, hiding the app, and installing systemless hosts and play integrity fix modules, searching for "google" in the deny list, and checking the box for every app listed (including system and OS apps), every time, after restarting the phone, it would have a working internet connection (WiFi and mobile data) for only a few minutes before both WiFi and mobile data would die and show no internet connection. I tested in safe mode, and didn't have the same issue. Then after rebooting, I used SwiftBackup to disable a ton of apps I suspected might have some potential to cause an issue with the internet connection, and rebooted again. Now it seems to be working okay. However, I'm afraid to reboot it again in fear it may stop working again, and also worried what will happen if/when I need to use one of the apps I disabled if that app might break the internet connection again.

I appreciate any help anyone can offer on resolving these issues. Thank you in advance!
