[Q] Editing /data/system/packages.xml

Hi guys,
I'm currently trying to manipulate the file /data/system/packages.xml in order to make Android start one of my apps with another user id. However, this doesn't work because it seems that Android recreates the file completely when shutting down the system which means the old user id is being written back into the file.
Without rebooting, changing the file's contents (or even deleting it completely) doesn't do anything either, it seems that the contents are being loaded into the memory on boot.
What I need are your ideas on how I can make my app run as another user (or edit the file permanently) I need this because I want to access another app's non-exported service.
Thanks in advance!
edit: Even if I try editing the file and then shutting down the system unexpectedly (One X, holding down power for like 10 seconds without using the software shutdown), the file is being restored after reboot. When I check the file in CWM after a normal shutdown, it's also back to normal. So I guess Android rebuilds it on shutdown AND on boot.. or something?
edit2: I just tried the following: Rebooting into CWM, editing /data/system/packages.xml from there, checking file contents (worked), rebooting system - file contents restored. I'm starting to think that this isn't the file I have to edit. But which one is it?
edit3: Tried editing /data/system/packages.list instead, didn't work either. The file is also being restored to the original state.

Wireless Keyboard problem on Vontar X1

Hello everyone. I recently bought a Vontar X1 4gb ram, 32gb storage. I came with one of those generic wireless keyboards+touchpad. Everything worked fine except the Enter key witch always typed q. After a little digging i found a solution to modify the Generic.kl file to remedy the problem. So i used a root explorer i went and modified a file with a text editor but when i saved it sayed "Failed". I don't know what happened but now the file Generic.kl is empty and the keyboard doesn't work anymore. Only the touchpad/mouse thing works. I connected a normal pc keyboard and it doesn't work either. Did a factory reset the Generic.kl is still empty. Found the file on xda, tried to replace it and "Failed" Tried copying the text from the download file to the on in the system "Failed". The box is rooted and the partition is set to read/write. I tought about reflashing the firmware but i didn't find a flashable file anywhere. Another thing that i tought about is trying to connect the box to my pc and somehow to copy the file through the pc but i don't know how. Any solutions would be greatly appreciated cause i am kind of desperate. Thank you in advance.
