Big problem with i9300

Hi everyone!
I was running crdroid 6.0.1 (after resurrection 5.6..0/cm 13), it was ok, but trying to install an apk to make virtual ram in my ext memory card, my i9300 turn of.
Now I can't do anything by Odin because in downloading mode Odin mode is in red and it doesn't detect my phone.
In recovery mode say " Installing zips or performing adb operations may still modify the system partition".
Tried to wipe but said " failed to mount /data /system (operation not supported on transport endpoint)
I want to delete everything to install a crom again but I don't know how to do it, somebody can help me please?
Thanks a lot
Ed

Samsung S3 i9300 Dead after trying to install a custom ROM (noob here)

So here is what happened.

I wanted to upgrade my android 4.3 to newer versions. I rooted my phone using kingoroot. It said it was successful. Then using TWRP manager app I tried to install the latest recovery image for samsung galaxy s3 i9300. It told me that it failed and that i could reboot now. i selected that but the app hanged (the rest of phone was working fine). then i manually restarted the phone using power button. it did restart but the screen remained black and the led (which glows red while charging) turned on and was changing shades of blue. I waited a bit then took out the battery. After that the phone is not turning on at all. I tried the soft and hard reset (pressing vol up+ home+ power button) but no luck. When i connect the phone to my laptop it gives a notification sound (ding!) but nothing more.

Please help me bring back my dead phone.

P.S: All this just to play pokemon GO

Samsung S3 i9300 Dead after trying to install a custom ROM (noob here)

So here is what happened.

I have a Samsung S3 i9300 with android jellybean (4.3). I wanted to play Pokemon GO real bad (damn me ! :( ) so I tried rooting my phone and upgrading it to 4.4.

I used the kingoroot from PC and successfully rooted my phone. Then i downloaded the TWRP manager app in my phone and went to install recovery (i have no idea what that is but i went as per instructions given on TWRP website), chose my device, the latest image available and then selected "install". It ran and then gave me a pop up that it is not successful because either the image is not for my device or my phone's "something" is locked (i don't exactly remember what it was.. but i searched and found out that Samsung galaxy S3 i9300 has "that" feature always unlocked). Then it gave me an option to "Reboot Now" and i chose that, which hanged my phone. I pressed the home button and it went to the home page and the phone was working OK besides the TWRP manager app which was stuck. So what I did was that I restart my phone using the power button. My phone restarted and then I got a black screen and the LED which indicates the charging status was blue (with changing shades), It got me worried so I took out the battery. When i put it again it was DEAD :(

I tried the soft reset, hard reset but no luck.

When i connect it to my PC it does give that connected sound but nothing else.

Samsung Galaxy S III I9300 - Download Mode

I've search around and everything I find looks kinda fishy.
I am planing on rooting my Samsung Galaxy S III I9300, but I noticed that my Volume Down keys doesn't work.
Is there anyway where I can go to download mode without using the Volume Down key?

Sorry for the short question.

Thank you.

[ROM][6.0.1][UNOFFICIAL]Paranoid Android 6.0 for i9300 [AOSP]

Ahoy! Once again, PA's back (for our device, I mean)! This time, this ROM isn't based on CM rather AOSP (The nexus sources). I don't know if there will be legacy sources as such, but looking at how today's ROMs are basing themselves off of AOSP-CAF and AOSP, I don't think they will but hey enough with the reading already, go enjoy the ROM :P

Bugs:
Gapps may not install on first boot, you'll have to boot ROM first, then flash gapps, then wipe data and then boot.
Keypress light is back to the old always-on kinda style (Tried various things, wouldn't work :/)

NOTE: This ROM is based on AOSP so it has that weird chipset-specific boot issue. So flash the included zip (Thanks @orsonbear)

Download:
AndroidFileHost
Bootloop fix (for users who can't boot their device)

Even then if the zip doesn't work, you can try @orsonbear's fix or @turbolukex5's fix

WiFi Doesn't Connect, Only Saved, Secured on S3 i9300

hi guys, my s3 i9300 wifi doesn't work , it says " Saved, Secured" since about 6 months ago.
the phone DETECTS the signal of a lot of wifi routers at almost 60 mt away, but don't connect, BUT when I go close any router that I have password ( almost 1 or 2 mts. from it )the phone check the ip address and connect.
first I thought that was the antenna, but if were it, the phone shouldn't detect the wifi router, and here is the problem, the phone detects the signal and only connect when is close to it (1 or 2 mt)
I tried changing the rom, it stays the same; reset my router ( or any other ( cause it happens with anyone else) nothing happen; in internet everybody says to reset phone, or reset router, but I think( I am not a developer) that the problem maybe in some system file ( probably in the efs folder, cause so many times I erase that folder by mistake, and when I have problem with the imei, I found solution to recover it).
there are a lot people finding solution for that problem, if you guys in XDA can help us we appreciate that
thank you
