Here is a little program that can obfuscate and deobfuscate Samsung SSD firmware files. I'm against obfuscation because it's a stupid malpractice aimed only to keep off unliterate people. Use as you please and drop me a comment/email if it was useful to you. Drop files here or Donations are welcome.

In the last few weeks I noticed a heavy battery drain on my Galaxy Note 3, which has always been perfect battery-wise. After further inspection I noticed that the phone stopped to go to "deep sleep" when it was connected to my home WiFi. I even banned my phone from my LAN, just to exclude any external cause. Nothing changed. I checked the wakelocks and didn't see anything "strange". After a few days of inspecting and testing, I found nothing.

What if one of my many tests launching "act...
