[Q] Boot Loop

I have a Samsung Galaxy S4 with T-Mobile (SGH-M919) on which i had previously flashed CyanogenMod 10.2
-I recently decided to get Android 4.4 on my device so I attempted to flash the AOSP {4.4.2} S4 Google Edition Final-R4
-I installed it through the "Install ROM from SD card" Option on ROM Manager
-When i rebooted the google logo came up, but then the phone loops on the 4 colored balls
-Also, the phone doesn't go into recovery mode, the screen just stays black until I finally let
Can anyone help me fix this? Or explain to me a way to at least reset the phone.

U can try flashing stock rom of ur fon through ODIN through PC....
Please, Don't forget to hit THANKS if i helped you!

well first of all, before you do what mohit378 said which is right, you need to see if it will go into download mode, im not sure the button combo for the s4 so you will have to look that up, then like what mohit378 said your going to need to find a stock your FOR YOUR PHONE MODEL ONLY on sammobile and flash that in odin.

[Q] Samsung Galaxy note 10.1 2012 stuck at "samsung" screen

Was playing some castle clash with my friends the other day and suddenly my note goes black and restarted. however after that is will not boot up. mine is stuck at the "samsung" with the swirling blue ....thing around the logo.
i see alot of people get to the "samsung galaxy note 10.1" logo and stuck there with no recovery, but min goes to the next "step" in the boot prosess, i have access to recovery and odin.
one odd thing, if the charger is connected it stays on the samsung logo over night. however without the charging it stays at samsung logo for about 1 hour then i hear the boot sound witch should have been played with the blue swirl and it reboots
and it all start over.
I use Android revolution 21.0 HD as my daily rom.
i have tried to dirty flash android revolution, same happends.
i have tried to wipe data/chache/dalvik/factory reset. same happends.
I have tried to flash Cyanogen 12.1 same happeds (exept now it get stuck at the blue cat pic with the pulsing circle behind it)
anyone have an idea how to proceed? it looks like a hardware problem to me, but ill ask here first.
Edit: Installed TWRP 2.8.6.0 and tried to install CyanogenMOD 12.1 again, it finished and i looked at the log/shell window and found "unable to mount /efs pretty sure that is the problem, however i see some conflicting info when i google. Anyone can tell me clearly what to do to fix it?
Edit 2: Issue fixed thanks to BaDaB!ng505 post number 4 here: http://forum.xda-developers.com/showthread.php?t=2204960
It pays to pay attention to log output.

Deleted the very first samsung boot logo

Hey guys, I accidentally flashed a rom and removed the battery during the process, my phone soft bricked (saved it, its not the question). However when I'm booting my phone up I get a weird screen as a system boot logo. I can understand that its the Samsung Galaxy S3 Mini GT-18190 boot logo because the brightness level maxes out. And the weird boot screen pattern changes all the time. How can I find the stock "system boot logo" and fix this issue?
(Can't put the image here because I dont have 10 posts.)

Can't you just re-flash the stock rom and fix it back to it's factory state?

Fixed it by downloading the original bootlogo (the one before the rom boot logo) from novafusion.pl and flashing it.

Sm-g920f / powered by android screen.

Hi, All.
Galaxy S6 stuck at android screen in black, the powered by android one.
Tried various combinations of flashing via odin.
Tried searching the threads.
There are a few discussions regarding this matter but none are definitive or even clarify what the problem may be.
The phone just went off unexpectedly, will not boot into recovery only download mode, will not go past the black powered by android/samsung logo screen.
flashed latest OS in odin, flashed android 6 and 5 too just too try.
Tried re-rooting/twrp, etc. the only thing that changes is that when it gets too the black logo screen it has seandriod recovery not enforcing.
will not enter recovery in any state or go past black samsung screen. when I flash I can get the binary to official but not the os. when i root i get the binary back to custom but still loads the black screen but now with seandroid not enforcing when attempting recovery.
Old firmwares bring up the check sw match in the download mode.
SO...NOTHING.
There are mentions in the threads about using old bootloaders, can anyone clarify the procedure/issue regarding this and if or not it may apply.
Any Ideas?
I understand the main motherboard may have possibly failed but this is not a definite when the phone is still booting into download.

How to restore stock boot logo and animation?

So I modded my Galaxy S7 (flat) with a custom rom. the custom rom was a port of the S8 rom with some tweaks and in the end I didn't like it because there were a ton of broken features so i flashed my TWRP backup onto the device and everything works fine except my boot logo and animation are not original. When I power up my S7 it shows up as if it's a Galaxy S8 booting instead of an S7. I know how to change the boot animation but I don't know how to change the logo that pops up when you first power up the phone.
Anyone know where I can find the original logo and how to replace it?
