[Q] Is it possible to perform really low level operation with XPosed modules? topic

Hi,

I'm trying to code my first XPosed module.
What I'm trying to achieve is very low level operations, such as reading/writing the process's memory, or hook the core library functions and run my own functions.
Can this kind of stuff be achieved with XPosed modules?
My first idea would be to inject a function that loads a custom *.so file that performs such tasks.
I was wondering if there was a better way, without the need to use .so files.

Thanks!

[Q] How do I perform the OTA update to Lollipop when rooted? topic

I recently unlocked the bootloader of an HTC One (M8) running Kitkat, installed TWRP then flashed a .ZIP file to root the phone. Now Lollipop has been released there's an OTA available on the phone but I'm not able to update through it. I've seen different posts all over the place about how you have to just install the stock recovery or how you have to use an RUU or how you have to use a NANDroid backup so the opinions are quite conflicting.

I basically just want the phone to run the stock unrooted version of Android so I'm able to perform the official OTA updates to Lollipop so how do I go about this? Any help is greatly appreciated!
