[Nexus 5 Q&A, Help & Troubleshooting] -Raffa-:
First of all thanks for the answer, I really appreciate it.

Well I tried million times, one time only recompiling, another time recomiling and adding to the new apk original META-INF and AndroidManifest, another I added also .arsc file, another I treid to sign the apk. Every time I got a bootloop.

I took other logcats I and noticed a recurrent error: (idk if it is usefull)
