4X extremely slow after rooting/reboot

---

So, I followed the guide we all did here:

http://forum.xda-developers.com/show....php?t=1818502

And before someone asks: I have deleted the Backup app (IS11LG_SystemBackupTest.signed.apk) we had to install during rooting after the phone was rooted.

The phone then happily ran, rooted. SUpersu was installed/updated, the phones root check said it's all perfect, I was a happy camper. But today I had to reboot it. I can't say if it was the first reboot after rooting, sadly. The phone boots up, arrives at the lockscreen (some colorful defaultthing, before I get to see my GO Locker screen after login), and then stops being responsive, it basically at first feels like it's not reacting at all. Some things are responsive, strngely ... I get accurate sounds when touching the screen for instance. If I then wait, I eventually get to the SIM Unlock ... which is also totally unresponsive, it will maybe show two digits, then freezes up. Strangely, I could type the remaining digits and hit OK and the SIM would unlock ... but the screen no longer showed what I typed. I then arrive at GO locker, can unlock it (sluggish and slow again) and finally am properly logged in, but still totally sluggish and slow. Needles to say it's a pseudobrick that way, unusable.

What's going on and what could I check?

• Remove the "SystemBackupTest" app, if you haven't already.
• On your phone, go to "Settings -> Developer options" and make sure "USB debugging" is TICKED
• Connect your phone via USB to your computer.
• Open a command prompt (may need admin privelages, right click, run as administrator)
• Type without quotes "cd C:\o4xr" and press enter.
• Type without quotes "adb shell rm /data/local.prop" and press enter.
• Type without quotes "adb reboot" and press enter.

Thanks, that fixed it! It's not easy to do, as the scrolling lists do not work, either, and you can't seem to get to the developer options, it won't scroll. Strangely enough "internally" it seems to do things ... if you re-enter the options, they're down to the end of the list, it looks like it doesn't update the screen properly (much like when I had to enter the SIM code).

Anyway, it's fast again, whew ... I was scared. What is the local.prop thing, if I may ask?

I'm not entirely sure, I just know it gives us temp root for the rest of the root script to run.

Hm, so its' not a systemwide ini file or so, that existed before ... it was created during the above rooting process and was an undesired leftover from it? I'm always a bit worried if I delete something with such an unspecific name in the OS

Its actually created by the SystemBackupTest app.

The script then removes it just before issuing a reboot.

The only way it can come back, is if you accidently open that app again before uninstalling it.

I see, I might have done that ... good to know. Anyway, great that it works again, thanks again
