S5 Does Not Boot

Problem: Hi There. I have a Samsung S5 Model SMG900FD SSN G900FDGFMH which I purchased in Bahrain 8mths ago. The data label states made in Vietnam. I am now living in Bali and am totally reliant on the phone for media,banking etc. Recently I found it will not start up. The start button works and the Samsung logo appears followed by sound and the Samsung coloured display. It then ‘hangs. I have tried everything including battery removal and various combinations of keys with the same result. I took the unit to Samsung Service in Denpasar. They advised a likely software issue and I will lose all data if they reinstall, however as the phone was purchased in Bahrain they advise they do not have software anyway.  travelled to Singapore last week and attempted help at a service centre there. Similar advice; as a dual sim purchased elsewhere they don’t have the software. The phone was sold with a 2 yr warranty but as I will not be returning to Bahrain it seems that it is worthless. Becoming disillusioned with Samsung I enquired at an iPhone outlet whether they covered their units globally. Answer was also to purchase in home country as if the unit crashed then unlikely to be able to be repaired elsewhere. So the message is to avoid purchasing outside your home location (and especially airport duty free when travelling). I now have a ‘lemon’ and must purchase another. I have other Samsung products including ‘Pad’, TV’s etc. Time to change and try my luck with an ‘apple’??? Any advice appreciated. Regards Peter (New Zealander currently living in Bali…without a phone!

Solution: If you have tried every troubleshooting procedure save for the reinstallation or reflashing of the phone software then you should probably try to do it yourself. There are various guides you can check out online on how to do this.

You will need the correct stock ROM for your phone, Kies installed in your computer, and Odin 3 installed in your computer. Make sure to have a backup of your phone data before reflashing your phone and make sure that it is fully charged.

General flashing guide

  • Run “Odin3” as administrator.
  • Click on PDA button (AP if you are using Odin3 v3.09) and navigate to the *.tar or *.tar.md5 firmware file (it will take a few second to check firmware file, if you are using Odin3 v3.09). If the Zip file contains more than one *.tar file then they will be labeled with PDA, Phone and CSC. Put them in the corresponding section of Odin3.
  • Shut down your device and make sure it’s completely off. Put your device into download mode by pressing and holding (Volume Down + Home + Power) buttons then Press Volume up to continue.
  • Connect your galaxy S5 to PC using USB cable and wait until you get a sign in Odin (ID:COM section) and “Added” in message box. Make sure re-partition is NOT MARKED.
  • Click Start and wait a few minutes until you see “RESET” or “PASS!”.
  • If your device stuck in bootloop, factory reset it from recovery mode.

S5 Randomly Shuts Down & Takes A Few Tries To Turn On

Problem: Hi, I read your article on troubleshooting the galaxy s5, but I think I need a bit more help. Earlier today me and a friend were at a pool, and yes, decided to see if we could film him diving underwater. I remembered reading somewhere that my phone (galaxy S5) was waterproof, but it turns out that it is water resistance, and that there was a difference between those. I put it underwater only just barley, no more than 2 feet under, and filmed a short video. We took some pictures, and it was working fine. Then we went to grab some lunch and when we came back we decided to do it again, but I don’t think the back was on firmly, because when we took it out again, the phone wouldn’t turn on. We took out the battery and the SD card and the sim card. We let them dry for a while in the sun, and put everything back in correctly. When we tried turning it back on again, the screen displayed a green robot (I think the android logo) and some small type in the top left (some was red, green or white color) and the screen, which was strange was flickering yellow, sometimes all of the screen sometimes random parts of it. I think it turned off after that. When we turned it on everything was fine, and working well, except the screens response was noticeably more laggy and slow than it was before. I put it down for a while but when I turned it on again the screen was flickering yellow and it was really weird, because that had never happened before. In fact just now, right next to me it just turned on and flicker (spooky). When we got home we put it in rice (case off and battery and the cards were in rice separated. I left it there for maybe an hour, but now I decided to get down to business and fix it. If I try to turn the phone on it usually doesn’t work and will maybe give a slight flicker for barley a second but doesn’t turn on. I took out the battery and cards and put them back in and held down the power button and now it turned on with the screen flickering yellow some more. It opened up to the lock screen, and I can type in the password and open some apps, (screen is still flickering) but then it randomly shuts down, and it takes a few tries to turn it on again. Please send help! Thing to note: This phone is 4 months old. I have a screen protector. No scratches or marks or dents in it (I made sure I never drop it). Ask me anything about it and I will try my best to answer.

Solution: The most likely reason why your phone is acting this way is because it has been water damaged. This is a difficult issue to troubleshoot unless the phone is opened and inspected carefully. The various components inside your phone have to be tested to verify which one is damaged and causing this issue to occur. The best thing to do right now is to bring your phone to an authorized service center and have it checked.

S5 Does Not Turn On After Overheating

Problem: Hello, I just read your article regarding the S5 not turning on. I have encountered this issue 2 times since the update. My phone will get really hot. I will power it off and then pull the battery and hold the power key. It usually would solve the issue, but 2 times it would not turn back on. Both times I have waited awhile tried to turn it on with no response. I, then, pulled the battery and put it back in. It has responded right away. Do you think this is a system thing from the update? I would think if the battery was bad that it would not turn back on. I appreciate any light you can shed.

Solution: If your phone is overheating it means that it is doing a lot of processing work. This could be due to an app installed in your phone or due to corrupt data. Since the S5 has a sensor that protects the phone from excessive heating you will not be able to turn on your phone unless the temperature drops to a certain level.

Once your phone cools down you should turn it on and immediately check what is causing this issue to occur. Start by checking if an app installed in your phone is the main cause. You can do this by starting your phone in Safe Mode.

  • Turn the device off.
  • Press and hold the Power key.
  • When ‘Samsung Galaxy S5’ appears on the screen, release the Power key.
  • Immediately after releasing the Power key, press and hold the Volume down key.
  • Continue to hold the Volume down key until the device finishes restarting.
  • Safe mode will display in the bottom left corner of the screen.
  • Release the Volume down key when you see Safe Mode.

If your phone does not overheat in this mode then the issue may be caused by an app. Find out what app is causing your phone to overheat and uninstall it.

If however your phone still overheats in Safe Mode then the next thing to do is to back up your phone data and do a factory reset.

  • Turn off the device.
  • Press and hold the following three buttons at the same time: Volume Up key, Home key, Power key.
  • When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
  • When the Android System Recovery screen appears, release the Volume Up and Home keys.
  • Press the Volume down key several times key to highlight ‘wipe data / factory reset.’
  • Press Power button to select.
  • Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
  • Press Power button to select and start the master reset.
  • When the master reset is complete, ‘Reboot system now’ is highlighted.
  • Press the Power key to restart the device.

S5 Shuts Down Randomly & Won’t Turn On Unless Battery Removed

Problem: Hello my Samsung Galaxy s5 shut down after inactivity that happened  after i went into the pool and i have to remove the battery and reinstall it for it to work thank you.

Solution: Did this issue occur after your phone got wet in the pool? If it did then you have to make sure to completely dry your phone first by taking out its battery and placing it in a bowl of rice for at least 48 hours. The rice will absorb the moisture inside your phone.

If you are still having a hard time turning your phone on then you should bring your device to an authorized service center and have it checked.

  1. I have a Galaxy 5 from Canada and while on, would not come out of black screen. Tapping the screen would produce a flash of app page. Nothing else would work to repeat that flash just more tapping of the screen. Battery was disconnected and reinstalled. The Top Left red light would appear then green would appear. Unable to start. I hooked up the Galaxy 5 to my desktop with Smart Switch but Smart Switch needs the Galaxy 5 on to work.

  2. Hello. A few days ago my phone overheated from being placed in an entertainment cabinet with several different electronic and improper venting. Since then it gets stuck in a rebooting mode. As It is powering up It will just shut back down and the “Samsung St active” will come on then go off , on, and back off and will continue to do so. However I can plug it in to charge and occasionally get it to fully power on. During that time I have deleted many apps and a lot of data. I’ve done a restart in safe mode. I’ve done a restart to reboot and clear casch. I’ve typed in the battery code. And am currently doing a BBC start. But it seems stuck. With the writing in top left little green guy center and it says Downloading… do not turn off target!!
    What to do???

  3. Hi again, I have read and tried all of the above posts, and I still get NOTHING. NO power, no buzz, nothing. Can the phone be completely dead? It worked perfectly yesterday and nothing happened to it….Thanks!!!

  4. Hi Droid Guy,

    After reading and trying all your suggestions for a Galaxy s5 that will not turn not on, mine still will not. It wouldn’t charge on the charger all night and this morning with 11% charge left on the battery, I removed it and tried to turn the phone back on, it would not and then showed this little robot icon and said “downloading do not turn off” that went away and the phone still will not turn on, buzz, anything. Any ideas??
    Thank you for any help you can provide. Tiffiny
