Can't Get Phone to Boot - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

Hello,
I accidentally pressed Format Data while I was on TWRP trying to wipe for a fresh install and now I can't get it to boot up. All i see is the Samsung Galaxy S4 boot animation and nothing more, Can anyone please help?
I think i screwed up my phone right?
Damn...

If you have a backup you should be able to restore your data

Long waiting times for boot ups! Galaxy Note.

Hi,
My Galaxy Note start having this long boot up waiting times after reverting back from ICS update.
The phone would wait for around 5 minutes on the Samsung splashing boot up screen and then a vibration with a light would emits the lower menu buttons when the phone is about to start.
It's like the waiting time for "Android is upgrading... Scanning applications XXX - 296" on the ICS!
Any help or ideas on how to fix that? Maybe a change in the numbers of "boot up timeout" file or something, if there's any can fix it???
Thanks!

Have you tried clear cache n wipe data?
Yes I've done cache wipe, dalviks cache wipe, system restore before reverting back!!!!
some time post flash it needed.
you can try again still not works, Reflash stock ROM again
I really have no time of doing so, it's time consuming...! Can I do that and then apply CWM backup restore??? Or it's going to conflict?
Cwm backup will push system junk if restore completely, so restore data only

I haven't had the need since going to the Note, but there's a neat program called alogcat which, for the boot animation, shows the logcat file scrolling by.
It might be useful to see what the Note is grinding on as it's booting up.
I used it for my mytouch 4g. Also nice to know that the boot is actually still 'booting' versus totally hung.

How do you go over th boot menu in alogcat? You just scroll and search for boot?

Which recovery do you have?

If you can get into dl mode, and hopefully you made a nandroid, flash this:

As soon as it finishes, hold power, volume up, and home simultaneously to boot into recovery. That should get you out of the water
Edit: my fault, didnt read closely enough. If you have a microsd adapter for your computer, save a copy of the stock rooted on your sd card via your computer and try a new flash. Sounds like you may have gotten a bad download

You might want to try this one click of the stock image. Just run the program, put your phone in download mode and flash. I would recommend doing a full restore just in case http://www.rwilco12.com/downloads.php?dir=Files/Devices/Samsung Galaxy S4 (SPH-L720)/Stock ROMs/MDC

[Q] Need help with VZW Note 3

Hi I rooted my brothers Verizon Samsung Note 3 which was on 4.4.2 NC4, Installed the safestrap recovery and have setup Hyperdrive on rom slot 1. My problem is when I try to access the stock rom slot it hangs at the Verizon logo. I've pulled the battery and same result time after time. I flashed a prerooted de-odexed 4.4.2 nc4 stock rom to the stock slot and it still hangs at the Verizon screen. Today I tried to do a factory wipe on the stock rom slot to see if I could flash another rom to it and it said it could not mount /system and /systemorig. Can anyone provide some info as to how I go about fixing this so he can have his stock rom back? Thank you.
Odin back to a stock ROM, non-rooted. If you want to, you'll have to start the root process from scratch.

That's what I figured the answer would be. I do have a 4.4.2 NC4 non rooted stock to flash. Thank you for your help.

One thing you might try first. I don't know about your initial problem getting stuck at the boot screen. But I tried the other day to do a complete wipe and wound up with the "unable to mount" errors. I had to go into the Mount screen in safestrap and uncheck all boxes, then recheck everything. For some reason, I had to click the System box several times to get the checkmark to show up. Might be worth a shot. Helped me avoid the hassle of having to odin back to anything
When I setup the 1st custom rom on the sd card I accidentally did a full wipe and after that I've been getting unable to mount errors like you stated. I will try that this weekend when I see him. Thanks again for the help and I'll report back with the results.

Clicked system for 10 minutes and the check mark will not show up.

Sorry to hear that. I wish I knew more about the error. Or the "mounting process" that seems to have failed. It was only by luck that I figured it out on mine. I was already downloading the files to odin my phone back and start over when I lucked out. Figured I would pass it along before you had to lose all you had done. But I'm not sure what else you can do at this point. Maybe someone else will chime in.
I was able to successfully recover from a "hang at the Verizon logo" soft-brick on my NC4 4.4.2 Note 3 by following the directions in this thread: http://forum.xda-developers.com/showthread.php?t=2483380 It seems like it might be worth a shot.
I tried flashing 4.4.2 NC4 non rooted and now it just hangs at the Verizon screen. When it boots up it still shows the custom logo under the Samsung Note III logo as well. What can i do or is it time to get a new phone? Thanks.

Click to expand...
Click to collapse
i'm having all the same issues you are... I cant even install new custom modified or non note 3 apks... you may have to factory reset one more time after ODIN.
I can't even get into recovery to factory reset it. We destroyed it. Lol. Just going to buy a new phone.

Replaced the phone but I'd still like to see if I can fix this one.
Does anyone have a prerooted 4.4.2 NC4 tar.md5 or other tar.md5 that I could flash in Odin? I have tried the stock 4.4.2 NC4 tar.md5 and it still just hangs at the Verizon screen and it just reboots when I try to enter recovery to factory wipe it. I have the 32g pit file already. Thanks.

[Q] Need some help

Rooted a friends note 3 so he could be free from lock down and now he wants the note 4. Tried to unroot it by using the feature in supersu and uninstalled safestrap and when i went to show him how to wipe it in stock recovery it wouldn't go to the recovery. Trying to avoid using a computer if possible and Odin back. Anything I can do?
Sent from my SM-N900V using XDA Free mobile app
OK I think I know why I couldn't get into stock recovery but I have another question. Is unrooting using supersu and wiping data and factory reset good enough to send the phone back in for trade if I didn't install any roms just rooted or will I need to Odin back to stock?
Sent from my SM-N900V using XDA Free mobile app
I generally find that it is easiest to use Odin and the stock firmware (make sure it is the right firmware for the version of android that is on the phone). It will remove root and put the phone back to the condition it was in when it was purchased.
OK so I used Odin and got his phone back to stock but it seemed to have deleted every photo he has taken in the past 5 months. Does anyone know of a way to get them back without having to root his phone again?
