I have an S4 i9505, never rooted or flashed any custom roms. Running the latest OS version from Samsung.
Phone was on the desk while I was working, suddenly it vibrated and turned off.
Now it's stuck in a boot loop, sometimes gets stuck on the Samsung logo.
Tried booting to recovery, worked on my 3rd attempt. Wiped cache, booted past the logo into the carrier logo and the SAMSUNG logo and then went back in the loop.
I have not installed any harfmul apps, I don't want to do a factory wipe yet because of precious data on the device.
Is there anything more I can try?
Download a stock ROM for your device from sammobile.com and install it using Odin. Since Odin doesn't wipe data when it installs, your data should be safe. With luck, the reinstall will correct your bootloop.

I'm not sure why i can't get it working but i was flashing back to stock rom. I have the correct rom and everything flashes fine on odin. I am unable to reboot to recovery. it says its loading and goes to black screen, and tries to boot to OS again. I tried flashing twrp with odin and same thing. I flashed the stock rom multiple times and it just won't boot. I even used Kies to flash it to stock rom and it was successful however stuck at boot logo again. The one thing i didnt do was wipe data/cache etc before flashing to stock rom but every tutorial i seen doesnt state to do it before the flash anyway. Has anyone ran into this problem before?
How are you able to get into download mode to flash rom but not be able to go into recovery? I had this issue once with my note 2 and went into recovery and wiped data and rebooted successfully....
I recently installed Cyanogenmod 10.2 then wiped factory data and cahces the whole 9 and now when I restarted the rom it wont boot past the samsung logo I even tried restoring a nandroid backup of the original rom rooted and it still wont boot past the samsung logo, im unsure of what to do and its really frustrating any help would be much appreciated thank you
You should do the wipes before you flash the rom. You booted up without a system to boot to. Odin maybe your option at this point
A few weeks ago I rooted my Samsung Galaxy S5 (G900H) and flashed a custom ROM on it. But after a few weeks I reflashed the original 5.0 ROM. I then installed cwm and rerooted my phone but something didn't go well because it failed to open cwm 2 out of 3 times, some apps failed to recognize it as a rooted phone (because of improper root maybe) and even some Samsung features were having a trouble in running and my phone was lagging and hung, a lot. So I backed up all my data and decided to do a factory reset.
I went into recovery and pressed on wipe all data/cache but it hung up while formatting. After half an hour or so I pulled out the battery only to see that my phone was stuck on the Samsung logo on boot.
I can't reformat it again as it keeps on saying error mounting data. So I decided to flash it with pit and the android 4.4.4 but since I had my reactivation lock on and usb debugging off, I couldn't flash it with anything.
Please help me in getting out of this situation.
Rooted S5 running Lollipop. Followed the instructions here: goo. gl/QkooVR to upgrade to Marshmallow and keep root.
I flashed the stock ROM with FlashFire and set the reboot mode to download. Everything was fine except that it never booted into download mode, it just froze at the Samsung logo, so I waited 30 min, no result, took the battery out, put it back in, went to download mode manually.
Then I installed the PF4 tar.md5 file via Odin. Again, everything went fine except it never booted up properly and was again stuck at Samsung logo. So, I waited 30 more minutes, no result, took the battery out, put it back in, manually booted into stock recovery. Checked the android version and it said it was 6.0.1.
Tried installing the md5 file several more times, same result. Tried rebooting without installing it again first, same result. What do I do? Should I wipe data partitions and dalvik cache? If I do, then what happens?
I have a faulty Galaxy S5 (G900M). One day I was using it normally and suddenly it rebooted and wouldn't boot to the stock ROM anymore, being stuck at the boot logo. I then decided to install CyanogenMOD and it worked. Now I want to sell the phone, so I want to revert it to stock ROM, but flashing a stock firmware gives me the same error as before.
What can be the issue?
First boot can take as long as 15 minutes. Did you allow such a length of time? IF so, pull battery, boot in recovery, wipe cache and dalvik cache, boot system and try
