4X extremely slow after rooting/reboot
So, I followed the guide we all did here:
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?
