[Huawei P8max] wendyalison:
Nearly bricked my phone from flashing stock Xposed (xposed-v87-sdk23-arm64.zip), after flashing it via TWRP and rebooting after the procedure, the phone boot-looped at Huawei Logo boot screen and got stuck there. I panicked and tried to go into TWRP (vol up + power button) and it goes into EMUI recovery (the instructions were all in Chinese, after trying to install the recovery package via Wi-Fi per the instructions and failing, I thought my phone was screwed for good), but here was how I got back everything in the end and even have Xposed down!

NOTE: MY PHONE WAS ROOTED PRIOR TO THIS AND WAS ON EMUI 4.0, ANDROID 6.0, DAV-703L (I rooted using the rooting guide!), IF YOU DIDN'T HAVE THIS ALREADY, THE FOLLOWING INSTRUCTIONS MIGHT NOT WORK FOR YOU!

1. Plug your turned-off phone to PC with USB, go into USB recovery mode (vol down + power buttons pressed down for a few seconds until it powers up to the screen with the android mascot and "PHONE Unlocked" in red letters), use the packages from the P8 Max Root Guide on PC, and then follow the same instructions for where you install TWRP (flashboot boot.img, and etc.)

2. Boot into TWRP (you'll be so relieved seeing the TeamWin bootscreen!), ensure you can see your data and stuff on internal storage and external storage.

3. Backup your stuff now, while you have the chance.

4. Now on your PC, download the uninstaller for Xposed, put it in your phone storage (external SD is also fine in case you cannot get back into internal storage via PC), have TWRP install/flash it.

5. This doesn't fix your phone yet, it still keeps boot-looping (trust me, I've tried it), so now on PC download the latest package for KangVIP Slim, and put it into your phone (or ext SD, whatever works for you as long as the zip files can be seen/read by your phone eventually), unplug your phone from PC.

6. Boot back into TWRP and flash/install the 1gb plus "P8MAX_KANGVIP_SLIM_B211_8_18_16.ZIP" file (or later) you downloaded earlier. Once installed, it should reboot on its own or you reboot manually. The other package is if you need to reinstall the apps KangVIP removes and is a lot smaller (that one is OPTIONAL)

7. You will see a new greyish Huawei boot logo, after which is a long EMUI Systems Optimization procedure (takes over 30 min if you have a bunch of apps and stuff installed). Eventually you'll boot back to your usual desktop.

8. Some things might have changed such as your usual wallpaper, and some system apps and equivalent widgets gone, but all in all, you get back everything PLUS Xposed safely installed (sdk23 arm64 v86 framework when I checked, so that might be why I nearly bricked my phone as I got the v87 framework)

9. You can tweak some stuff via "K Settings' in your "System Settings" to get back to how your phone interface used to be like and even get some new nice modifications in place.

Previously I had rooted using TWRP (nearly bricked my phone that time as well when the phone kept boot-looping to Teamwin Recovery, but managed to get back into regular boot via a backup recovery.img downloaded from the mentioned root guide). My biggest piece of advice is FOLLOW instructions and be emotionally and financially ready to buy a new phone or lose ALL data if you haven't backed-up prior to tweaking your phone. ANOTHER piece of advice, ppl like ajsmsg68 and Hirs_E_Fruit should get major thanks, love, and donations because they basically saved my flippin' phone (and many others), not just from bricking but all the data and everything within, ALL while rooting and unlocking essentially everything in the darn thing.

Hope all this works for people who struggled to get Xposed.
