S8+ Bootloop After Software Update

Problem: I have a Sprint Galaxy S8+ which I purchased shortly after its release last year. For the past 10-11 months, I’ve loved the phone. I typically root my android devices to install custom ROMs and remove carrier bloatware, but I have not felt compelled to do so with this device. Yesterday (3/14/18), I got a notification that an update was available. It looked like the same type of security patch/bug fix minor update that comes along every few months, so I thought nothing of it. I downloaded it and when I returned to my office, I made sure that my battery was above 90%, then hit the button to restart and install. After the update applied (seemingly without issue), the phone restarted, but only got as far as the “Galaxy S8…Powered by android” screen. It would sit there for about 20 seconds, then reboot back to the same screen. After about 30 minutes of this, I attempted to power down the device so I could boot to recovery and perform a cache wipe. Wouldn’t power down, so no luck. I was, however, able to boot into download mode. Finally, the battery died. I plugged it in and within a minute, it went right back into the boot loop. I let it charge up completely anyway. Next step, I manually flashed an official firmware from Samsung using the latest version of Odin I could find. The file took almost 3 hours to download to my PC before I could even attempt to install it on my device. I booted the phone into download mode, started up Odin, selected the proper AP file and hit START. Everything worked exactly as it should. Odin said “Success!” when it was finished. The phone, on the other hand went right back into the boot loop. This time, however, after about 20 minutes, the screen went black. No combination of button presses have any effect. I connected to a charger just to see what would happen. The circle with the lightening bolt in it appears, but the circle never fills. That’s where I’m at now. At my wit’s end. My next step is to take it to the Sprint store, but I don’t have insurance so I doubt they’ll help. I am desperate for any suggestions. A simple OTA update bricked my phone beyond anything I’ve experienced before.

Solution: Since flashing the phone with a stick firmware file using Odin fails to work then this is most likely caused by a hardware component that is failing to work properly. This component might have failed at the same time the phone was performing the update which is why it might look like the update is causing the problem.

The best thing that you can do right now is to bring the phone to a service center and have it checked.

S8+ Is Not Charging

Problem: My phone at first , was draining my battery, from 24% to 0%. Now when i charge it, its not working, i used my dad’s phone to charge, it works for his phone but not mine. Now it’s 0%, no matter i use which kind of charge or plug, it’s still the same. I don’t have a battery to take out to change. So could you help me please??? I have lots of important information inside and its Samsung S8+

Solution: You should try cleaning the charging port of the phone first using a can of compressed air. Make sure to remove any dirt or debris stuck in the port as this could interfere with the charging process. Once the port is clean try charging the phone for at least 20 minutes using a different charging cord and wall charger. You should also check if the phone can charge using a wireless charger or from a computer USB port.

In case the issue persists then this could already be caused by a faulty hardware component possibly the battery or power IC. The best thing to do right now is to bring the phone to a service center and have it checked.

S8+ Not Turning On After Drop

Problem: I recently dropped my samsung galaxy S8+ phone, it had a protective cover on it. nothing is physically damaged on the outside. screen is intact, I have tried restarting my phone several different ways. Pressing the power button and volume down for 1 to 3 minutes .Taken SD microchip out and other chip out… nothing is working. A blue light appears at the top of the phone and the noise comes out like it is starting, but the screen is black.

Solution: It’s likely that the drop has damaged a component inside the phone. You can however check if another factor is causing this problem by following the troubleshooting steps listed below.

  • Charge the phone for at least 20 minutes using a wall charger.
  • Turn on the phone by pressing and holding both power and volume down buttons for at least 10 seconds.
  • If the phone does not turn on then try starting it in recovery mode. From here I suggest that you do a factory reset. Take note that the reset will erase your phone data.

If the above steps doesn’t fix the problem then you will have to bring the phone to a service center and have it checked.
