How to Recover Samsung Galaxy S5 from Bootloop and Nearly Softbrick Fix

If it happens that your Samsung Galaxy S5 ended into bootloops, here is how to fix recover it and bring it back to life.  Bootloop mainly only occurs on your Samsung Galaxy S5 if somehow you have messed-up from customizing the system files. Some modified system files are not compiled correctly or if it is it might does not matched with your Samsung Galaxy S5 versions. The Samsung Galaxy S5 comes in different  model variants, each model version uses a different approach onto the system files.

When we have done far enough into customizing our Samsung Galaxy S5 such as rooting, installing custom recovery, custom ROM, other mods and even themes. So bootloops problem basically started here,  if someone had missed figuring it out that each and every custom images has a different build versions that fits on each Samsung Galaxy S5 model variants.

What is Bootloop?

The phone is experiencing constant reboot, auto restart and cannot boot normally.  It couldn't passed the Samsung logo and welcome screen and just stuck in there.  That means your phone is in trouble and you cannot use it anymore.

To easily fix a bootloop  you may only need to find out when and how the bootloop occurred. Is it during the last time you installed a custom recovery, ROM, root kernels and any other mods?  Below are the following reasons causing your Samsung Galaxy S5 turned into unwanted bootloop, just try to figure out on each and then recover your phone to the given solution.

Fix and Recover Samsung Galaxy S5 from Bootloop After Installing Root

If you just installed root image into the system file and then it turned out bootloop once you reboot your Galaxy S5, then there must be something wrong during the flashing process. It's either you have flashed the wrong root image which it doesn't matched with your Samsung Galaxy S5 model number or the root images has not recently updated yet to worked with the current Android version of your Galaxy S5.

You have flashed the wrong root file that doesn't matched with your Galaxy S5 Model number.  

If you messed-up and turned your Galaxy S5  into soft-brick then simply flashed the correct firmware file according to the phone's model number.
  • SM-G900F (International)
  • SM-G900H (International)
  • SM-G900I (Australia and New Zealand)
  • SM-G900L  (The Americas)
  • SM-G900M (The Americas)
  • SM-G900A (AT&T )
  • SM-G900T (T-Mobile US)
  • SM-G900P (Sprint)
  • SM-G900T1 (Metro PCS)
  • SM-G900R4 (US Cellular)
  • SM-G900V (Verizon)
  • SM-G900W8 (Canada)

Read one of our root guide here for the international Galaxy S5 variants - Root international Samsung Galaxy S5 SM-G900F. Once you flashed the wrong root file that let say it was only built for the international Galaxy S5 SM-G900F and you flashed it with your US version of Galaxy S5 then it will also caused into sudden bootloops.

Root image doesn't seem to worked with the newest Android software update version

I have not seen this occurring  on Galaxy S5 for now, but it might also caused once and every future software update to come out.  Samsung might also try to released some patches to the Android ecosystem that might prevent from customizing.  So it will also take sometime  for the root developer to find some exploit to the patches so it will worked with the latest version. Like for example, if you have successfully rooted before with the same Android version like 4.4.2 (KitKat) and then Samsung has recently rolled out another build version like Android 4.4.3 (KitKat), so there is an adjustment going around here.

Fix Bootloop from rooting: Wipe Data Factory Reset

Reboot your Samsung Galaxy S5 into recovery mode then perform  a full wipe or data reset. This will  not absolutely clear the root image you have previously installed but just clean  and reset your phones data settings.  From here your stored will be lost, since you cannot perform back-ups if your phone is already in bootloop state and you don't have any custom recovery installed to do that.

1. Set the phone into recovery mode. First turn the Power OFF, then by holding down the Volume Up+Home and Power button at the same time.
2. Once in recovery mode screen, choose "Wipe Data /Factory Reset".
3. Lastly choose "Reboot System".
4. Then it may boot normally without bootloop.

If the bootloop problem still exists, then you need to try to restore the phone's original system files. See below recover bootloop by flashing the full stock firmware.

Fix and Recover Samsung Galaxy S5 from Bootloop After Flashing a new ROM

Flashing a new ROM into your Samsung Galaxy S5 will also caused bootloop problem. This is basically happens when you flashed a new base ROM on top of the previous ROM you've used and you forgot to perform the  a full Wipe dalvik-cache clean-up. To fix this problem try this solution.

1. Reboot your Galaxy S5 phone in Custom Recovery you installed such as CWM, TWRP and or Philz Touch recovery. First turn the Power OFF, then by holding down the Volume Up+Home and Power button at the same time.
2. Perform a select “Backup & Restore”.
3. Choose “backup” first to keep your data files in safe place.
4. Head-over  to the Advanced options.
5. Choose “Wipe dalvik-cache”.
6. Then go to “Mounts & Storage”.
7. Choose “Wipe /cache”.
8. Select Reboot the phone now.

If it doesn't fix the bootloop problem, then proceed to my last solution below on how to restore the phone's original system files. (See below recover bootloop by flashing the full stock firmware).

My Galaxy S5 cannot Enter in Recovery Mode.

If you cannot set your Samsung Galaxy S5 into recovery mode, then the above bootloop solutions will not worked for you anymore.  At this state you phone is has ended into soft-brick.  Now, let's try a different approach from here and try this solution.

1. Turn Off the phone, then pres and hold the Volume Down, Home and Power button.
2. See if you can access the download mode screen and we still have hope to fix that bootloop problem.
The download mode then displays an Android robot and say’s “Downloading.. Do not turn off target!”

If you cannot access that download mode screen then, the below solution will no worked for you and I only suggest that you may need to send your phone to your nearest support centers.

Fixing bootloop by Restoring back your Samsung Galaxy S5 original firmware

Using the stock firmware is an advantage for fixing soft-bricked phone once the its system files has been compromised and resulted into bootloop and any among other issues. This is a bit complicated since you need to download a large firmware file for your Samsung Galaxy S5, but I can a assure you that this is your last resort to bring back your Samsung Galaxy S5 from nearly softbrick to usable again.

Here are what you need:
  • Odin3_v3.09 - download
  • Galaxy S5 USB Driver  - download
  • Download and select the correct stock firmware file according to your Galaxy S5 model number.  Samsung Galaxy S5 Original Firmware
  • The supplied USB data cable of your Galaxy S5
  • A Windows based computer or laptop
  • A fully recharge battery

Run and Configure Odin
Run Odin downloader Odin3_v3.09 in your computer.  Configure these check-boxes options on the right top of Odin, ensure that the ‘RE-PARTITION’ has no check marked. Just leave alone the the ‘AUTO-REBOOT,  ‘F.RESET TIME’ check-box remained checked.
Reboot your Galaxy S5 into Download Mode
To reboot the Galaxy S5 into download mode , you need to turn the power off. After it completely shut off, just press and hold the Volume Down key, Home button and the Power ON/OFF button simultaneously.

You should then prompted into a warning screen and asking you to press volume up if you want to continue or volume down to cancel, just simply press volume up to get into download mode. The download mode then displays an Android robot and say’s “Downloading.. Do not turn off target!”
Connect your Galaxy S5  to your computer or Laptop
Once you already reboot the phone in download mode, simply connect the phone to your PC or laptop USB.
In Odin window – the ID:COM box will turn to blue color and indicates the COM port number and a word “Added” on a log box will prompt you that the device is already detected or recognized by Odin. USB port numbers in Odin download mode starts from zero to  seven. If you do not see a COM port number then there’s something missing or went wrong. You may read again from the top of this post.

Simply click on the AP button, then browse to the folder where you put the stock firmware file that you have previously downloaded and then select and load it.

Once if all set and ready to fire-up, hit the “START” button in Odin to begin flashing the stock firmware.

Just wait until it completely finishes, it may takes a while to flash a huge stock firmware file. So just wait and relax until it finishes flashing.  Avoid interrupting your computer and your Galaxy S5 while the flashing has started, such as disconnecting the USB data cable or turning off the device.
