Bricked Phone during root. 720 Model - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I encrypted my phone several months back. Today I decided to root the phone. I followed the directions here http://forum.xda-developers.com/showthread.php?t=2291827. Problem is phone won't boot. I get to the enter password screen, but once I enter the password the phone shuts off. Please
Update. I tried reinstalling the stock rom using odin, but even though odin said the install was successful. I still have the same problem. I enter the password and the phone shuts down

Did you try the Factory reset in the stock recovery to remove password ( and also your data) ?

Rooted with CF-Autoroot, now encryption not possible anymore

I just rooted a brand new Galaxy S4 on i9505xxuemke
Before I encrypted and decrypted several times. Always worked great. Now after root when it should encrypt display shows shortly the green android and then it goes black. Device does not react anymore. After about 1 minute it vibrates and reboots. However I don't have to enter my password to boot. Only to unlock. Now I can go to options and try encrpyting again. Hower same behaviour as before. Any suggestions?
There are no apps installed, no google account and so on. Its factory fresh. I even restored factory settings. Same behaviour.
Any ideas?

[Q] Unable to boot after encryption

Hi everyone,
I enabled the encryption on my unrooted unlocked G2. Once the encryption was done, it rebooted and asked for the pin to boot. In entered the pin but the phone keeps rebooting and asking for the pin again and again.
I have tried more than 20 times, sometimes it boots to android but it shows a warning sign in notification (backup account needed) and then reboots after a few seconds. I tried turning on/off but the same thing happens again.
Is there anyway I can get my data out of this mess before doing a factory reset? Maybe rooting it from download mode and mounting from recovery?
Thanks a lot!

[Q] Can't disable factory mode because I can't root

First off, the phone is reading an IMEI of 0. The phone was rooted successfully, I did a factory reset to hopefully get the phone to refresh the IMEI information as it was disabling me from receiving data from my provider. The factory reset must of corrupted the root and now the phone gives me this annoying yellow block of info and says it is in factory mode. I have tried to root the phone to follow steps in order to disable factory mode but odin and the original motochoppa method are both failing.
I am now downloading an original firmware for the SGH-I337 but the phone is still in download mode from the previous failed attempt, it blatantly states "Do not turn off target!!" so I am under the impression I should leave it plugged in until this original firmware downloads and try again.
I would greatly appreciate the help from everyone here! Samsung wanted to charge me $70! And I know it is simply a matter of restoring it back to original firmware.
Issues-
-IMEI reads 0 in settings
-Phone was rooted successfully
-After factory reset root became corrupted
-Phone now stuck in factory mode (huge yellow box)
-Failed root attempts in order to disable factory mode
-Phone is now left on "Downloading... Do not turn off target!!"
1. Reboot ur phone in DOWNLOAD MODE again.
2. Flash the firmware that u downloaded before through ODIN.
3. Dial *#06# for see if you recovered your IMEI. If dont, you will have to pay what Samsung told ya for fix it.

Need help! Unlocking bootloader without using the app

Good day! I wanted to ask how to remove the bootloader for zenfone max (the old one 2015 model) without using the app from ASUS as I cannot really use my phone. It boots then restarts. I already tried Wiping/Factory Data reset and Wipe cache with the Power and Volume down (Is it Recovery mode?) but still bootloops, by the way when I factory reset, my phone showed "Unknown volume for path /factory". My friend told me it could be that my OS was corrupted. So here I am wanting to unlock the bootloader so I could install OS for my phone.
**Note1: Sometimes it would boot to the "Welcome!" screen, then when I reach to the Wifi selection, it would always restart.
***Note2: This bootlooping happened when I restarted my phone because my wifi suddenly couldn't connect. After I restarted, it looped.
Noob here btw. Sorry and I would be glad to provide additional information if needed be.

Samsung Tab A SM-T580 WIFI USA - Brand New, No Root, Boot Loop

I've purchased 12 of these Tablets for my company. Out of the box they were android 6.0, as soon as we connected them to WiFi the 7.0 Update option came up so we updated all 12. We then loaded our Comodo MDM enrollment on them. Well Next time they rebooted 9 of them would not come up, they just sit at the samsung screen fading in and out. I went into recovery mode to try factory reset & wipe, I get the message that "mdm does not allow factory reset". So I tried resetting the cache which did nothing as well. So I loaded Odin and booted into odin mode tried to load a stock rom and I get the message that the device is in FRP mode and cannot load a custom image...
I have ALWAYS had droids and I favor Samsungs normally.... I have always rooted and unrooted every device I've ever had, but these have me stumped... I cannot get into USB debugging mode, I cannot get the things to boot at all. Every tutorial requires debugging mode. Samsung Business support is NO help at all. So I turn to the dark side... HELP!!!

Sounds to me like the problem isn't with Google's FRP lock but with the Comodo MDM enrollment. First thing I'd do is contact their tech support. The FRP lock doesn't prevent you from flashing a ROM with Odin. The FRP lock would just ask for the Google login and password on the first reboot. And I have seen other security apps blame the FRP lock for not allowing a ROM to flash via Odin.
