[Galaxy Note II Q&A, Help & Troubleshooting] imatheus.sm:
First of all, my English is not that good, so I hope everybody understand me :)

I'm a flashoholic (i think this is the right expression); i flash a new ROM almost every two weeks. And, from some days ago to now i'm experiencing some problems. Here's my problem:

Problem: my phone "stucks" when I let it locked for more than some 5, 10 seconds. I lock it now, and... dead. I have to press the power button until it restarts. My phone is having trouble to find operator's network and it's EXTREMELY lagged too. It almost stucks when i try to write something on the keyboard, or draw/write my passwords on my lockscreen.

Here's my "ROM timeline", too:

ROM Timeline: MIUIBrazil v4 [4.1.2] >> P.A.C MILESTONE [4.2.2] >>

TigraROM/Hurricane [4.3 leaked]

>> MIUIAndroid v4 [4.1.2] >> MIUIBrazil v4 [4.1.2]

Bold = problem started

So, let me explain my history: flashing ROM's as always, I decided to change things a bit and go AOSP for a while. So I flashed P.A.C. Milestone. Actually, I've flashed first the Nightly version, but it was a bit unstable. I went to P.A.C and everything went fine. But, hey, where are the Samsung functionality? I missed it. So, after some trouble finding the right ROM to me, the 4.3 from Samsung leaked. I tried it, then. First the Hurricane, afterwards the TigraROM (Note 3 functions :)). And it was ok, but was lagging a lot. Too much launchscreen redraws to handle, so I went back to MIUI (not the first MIUI on the timeline, because I've decided to go right from scratch), and then, i've noticed a lot of problems.

It was not booting up.

I've flashed

A LOT

of ROM's trying to solve this problem. What it was? EFS folder. I went to the TWRP file manager on Recovery and noticed that the EFS folder was empty. And no backup. I went crazy until i found an old backup stored on my PC. Restored it right away, and everything was fine for a while... until it started doing some strange things like extreme lag and dead when locked.

And, when I went to recovery to look again to the EFS folder, it was always empty... i restored it again, again and after locked... BAM, disappeared. But some strange things are happening, like:

My bluetooth doesn't turn on.

My IMEI was fine, even with this EFS showing and hiding like that.

I'm almost finishing. Let me put here some basic questions that I know everyone will ask:

Q: have you tried to wipe everything and go from zero?

A:

yep. It didn't worked.

Q: is your IMEI ok?

A:

yep. But some things that are on the EFS folder doesn't wok, like Bluetooth. The MAC address of the bluetooth is there, but it doesn't show up when I write *#*#232337#*# on my Phone app (this code shows up Bluetooth address and try to turn it on... to me it tries to turn on forever).

Q: do you know that thing about the new modems? Click here to go to the post

A: yes, but only read it when i've had the problem. But i've restore that backup, and it was from the original ROM. So it doesn't seem to be this, because the backup was before this leak. Very very very before, actually.

I hope you guys can help me, and that I don't need to go to the Samsung support with the phone wiped. Thanks,
