[Q] i/o scheduler "null" topic

I am using galaxy y gt-s5360 running hyperion 9 gold final rom and savie#73 kernel. I also flashed a tweak Pure performance x stock edition downloaded from galaxyyarchive. My cpu governor is smartassv2 and i/o scheduler is cfq. After i flashed pure performance x, there is a slight lag on my phone. And my internet slows down, im not sure maybe because of my network. I downloaded a game through ucweb browser and at 12:00 am exactly. My phone hanged and i removed the battery and turned it on again, it is stucked on logo, i assume it was a bootloop, so i go to clockwork recovery default for savie kernel. I scroll and it hanged again. I just turned it off and charged it. I wake up 4am and i turned it on and go to clockwork recovery but the phone says no sd card installed even i have sd card inserted in my phone. I rebooted and a notification error occured that cpu set up failed and i go to settings>cpu set up and i see my cpu governor is smartassv2 and i/0 scheduler "null or unavailable" and i cant change it. So i reboot again and do a factory reset and nothing happened. Guys please help me. my phone cant read my sd card and i keep inserting it again. maybe its a bug from pure performance x, because i only get this problem after i flashed pure performance x. so guys help me out. thanks!

[Q] Rear camera firmware appears null topic

Hey everyone, this is my first thread and I am not native speaker so sorry for bad language.

The proble is that my Galaxy S5 is presenting a problem with its rear camera, everytime I oppen the app it says there was a problem and it closes with no explanation. Also I managed to check its firmware entering a code in the dial pad and where it says Rear Camera (main) everything is null. I am no expert, I am actually new at this but my first guess ir that maybe there is a missing driver or something like that?

Any idea how to fix this problem?

Thank you very much

IMEI Null / null / Baseband Unknown topic

Hello there..

Long story short, I bought a Note 3 SM-9005 LTE version from eBay.

The seller said the following:

Before upgrading to Android L 5.0 (Leak) the phone was fine (fully working, SIM working, etc)
After upgrading to Android L 5.0 (Leak) the phone was still fine but.. the SIM card stopped working. Actually, it stopped completely recognizing SIM cards. Also the IMEI turned into null/null and baseband into unknown (something that he didn't tell me.. and of course I found out alone)

Facts: *#1234# = Everything except the modem. It only shows the rest 2 but not the modem.

Also when I saw that the IMEI is null/null I remembered that the IMEI is available behind the battery (there's a label) but guess what.. it was removed..

Conclusions:

A) The phone was stolen by someone (Only the phone came no S-pen, Box, Charger, etc)
B) He indeed messed up with his phone and something got destroyed/corrupted. I don't know.

So I am asking you what can I do right now.. I really need to find a fix otherwise I'm opening a dispute case so I can take my money back.

Thank you in advance.
