Solved Samsung Galaxy S8 Custom Binary Error

The #Samsung #Galaxy #S8 is a former flagship phone released in 2018 that has some of the best features in a mobile device. It uses a 5.8 inch Super AMOLED display that occupies most of the front part of the phone since it doesn’t have a physical home button and only has minimal bezels. It also uses a powerful Snapdragon 835/ Exynos 8895 processor combined with 4GB of RAM allowing the device to run any app smoothly. Although this is a solid performing phone there are instances when certain issues can occur which we will be addressing today. In this latest installment of our troubleshooting series we will tackle the Galaxy S8 custom binary error and other related problems.

S8 Custom Binary Error

Problem: Hi, I have a Samsung Galaxy S8 – bought in Oct 2017 at the AT&T store – has been with AT&T ever since. I have no idea what operating system it had. My phone was working just fine last night. I wake up this morning and it is stuck on samsung screen.  I took the phone to AT&T and they tried to reboot and clear the cache, but neither worked — it looked like it was re-starting, but came back to the same screen. I took it to another phone repair store to try and have the memory flashed or something, but they couldn’t do anything either – said it was giving them a ‘custom binary’ message. I have not installed anything on this phone except apps from the Google Play store and the Samsung software updates that it says are needed. It did pop up a software update message yesterday. It downloaded and tried to install, but gave me a message the installation failed (like it does every time). However, my phone was working fine after that. I don’t know what happened overnight while I was sleeping (gremlins???) but it doesn’t work now

Solution: When you get a custom binary error on your phone this means that the system is detecting that the phone has an unauthorized modified software installed. There are instances when this could just be caused by a software glitch in which case you will have to try doing a factory reset from the recovery mode. Take note that this will erase your phone data.

If the issue still occurs after the reset then you will have to flash the phone with its updated stock firmware file. You can get the firmware file as well as instructions on how to flash the phone from the Sammobile website.

S8 4G Not Working When Mobile Data Is Off

Problem: I have an S8 phone. The first few months I had it I never dropped a call and always received my text messages. For the last 4 months or so I cannot keep a connection and cannot get my text messages unless I go out of my way to put my phone somewhere that will hopefully get signal. Went to Verizon store today to see if they could help. She noticed my 4G was not lit up and had a line through it. I just thought everywhere I was going I could not get a 4G signal so that is why it was not lit up and had a line through it. She reset my network and the 4G lit up, no more line through it. Which I had already done that before but did not pay any attention to whether the 4G lit up, it just did not seem to help. So when I left Verizon store I had to go into my settings and turn my mobile data off because I was afraid she might of turned it on. I never leave my data on because I do not want to go over on my data usage and I do not trust that some app or something is going to use my phone data in the background. So hours later I noticed the 4G was not lit up again and a line through it. I reset my network and it came back on. I went into my data usage and my data was on again and I did not turn it on. Turned the data off and I noticed the 4G light was out and a line through it again. How can this be fixed?  I need the 4G back on so I can hopefully be able to use my phone again but it keeps turning my mobile data on. I want my mobile data off unless I have to use it because I do not have access to Wi-Fi. I have no idea what Android Version this is. I just guessed because I had to choose.

Solution: Since 4G is a mobile data connection type you won’t be able to get this signal if you turn off the mobile data of your phone. The best thing that you can do in this case right now is to turn on the mobile data of the phone then manage the way your apps access the Internet.

You can turn on the data saver feature of the phone which will prevent apps from sending or receiving data in the background.

  • From home, swipe up to access Apps.
  • Tap Settings >  Connections > Data usage > Data saver
  • Tap On/Off to turn Data saver on
