I have a Samsung Galaxy S4 (SGH-M919N) from Metro PCS.
First I rooted it, then I flashed Cyanogenmod. I didn't like Cyanogenmod so I tried to flash it back to the stock rom. The problem is that there is no stock rom out there yet for my phone. So I used the stock rom for the T-Mobile version (SGH-M919). After I flashed it, the Cyanogenmod whirling blue circle came up so I knew something was wrong. It stayed on that circle for about thirty mins then I turned the phone off. Now, even CWM recovery won't come up(just the android laying on its back with a !red triangle above it) and anytime I try turning the phone on, it just goes back to the Cyanogenmod screen and stays there. Somebody please help me!

If you check the sub forum you'll find that there definitely are backups of our stock rom available. Theres no need to flash the Tmobile rom.

What you have is called a boot loop, not a bricked device. A boot loop is just what it sounds like...the boot animation (in this case, the Cyanogen boot animation) loops over and over. This can happen for a number of reasons and is easily fixed. Since it doesnt seem that you have CWM recovery installed any longer...I'm going to suggest you flash TWRP recovery instead. Relax...its easy :)

Go to the first link and follow the directions and you'll have TWRP recovery installed.

[RECOVERY][unOFFICIAL][TWRP 2.5.0.2]

Then go to the second link and follow the directions to restore the stock rom that your phone shipped with.

[Stock Backup] Restore Using TWRP

After following these you will have the phone back to factory.

Please....Read before you Do.

Let me know how it works out :)

What I ended up doing was reflashing the CWM recovery (sorry about that I did it before I read your post haha) and I did a factory reset of the data, partition, and dalvik. then I flashed VirginRom to the instead. And this seemed to work as I can finally use my phone now.

Also it would be really helpful if you could link the stock rom for SGH-M919N because I can't find it. Thanks!

No problemo. Glad you got it back :)

You misread me. There is no stock rom that you can flash for our phone yet. What we have at the moment is a Backup of the stock android OS that can be Restored via TWRP recovery and one for CWM recovery too (they are not interchangeable). Its a good idea to keep the CWM backup on your phone in case this happens to you again.

Heres the link for the CWM backup of our operating system:

lol, They're sort of the same thing actually, in that they are both operating systems that are compressed and packaged so that you can install it on your phone via recovery.

I just wanted to be clear that i was talking about a backup of a rom and not a rom like VirginRom because rather than using "install" in CWM to flash it (like virginrom and cyanogen), you have to use "restore" in CWM to restore it. Cause its a backup (that someone made by hitting "backup" in CWM) of the stock android os from that persons phone (without the data portion, cause thats private). This is called a Nandroid and is compressed and packaged by the recovery and then posted by a helpfull user. Have you ever used the backup part of CWM?

Now that your phone is running, you can boot into recovery and make a backup of what you have on your phone right now, including the data and apps, so that you can restore it back to that state whenever you need or want to.

Just about every thread recommends making a backup before you flash anything....no one listens :( lol

I glad my post was helpfull :)

Okay I understand now! So I guess the only way to restore that backup is by restoring from sd card (I tried restoring from internal storage but it doesnt recognize the backup file) and the problem with that is that the backup is 2.11 gb and my sd card is only 2gb, is there a way around this?

There's not much you can do about the file size except get a bigger sd card lol.

I haven't used CWM in a while (preferring TWRP) but i think you can restore from the internal sd with CWM. You might have to select restore first, then look for something like "advanced restore" i think its in there, something like "restore from internal sd".

Perhaps someone in-the-know can chime in here....
