Problem:i updated my s4 (i9500) with cyanogenmod 5.0 lollipop and once tried to reset from settings and now it only shows samsung logo for some time and wont boot up…..i also tried to enter recovery mode and download mode but it wont work….plz help me
Solution: Did this problem occur right after you installed CyanogenMod on your device? If this is the case then the issue could be with the flashing process. Try to verify that the firmware file you installed in your phone is compatible with the specific phone model. If the wrong firmware is flashed to your phone then issue could occur such the phone not being able to start. If possible, download the firmware file again then flash your phone. Make sure that you have a backup copy of your phone data before doing this.
If you have been using CyanogenMod on your phone for quite some time now without any issues then suddenly this issue occurred then there may be another factor involved. To troubleshoot this issue take out the phone battery and microSD card ( if your phone has one installed) then press and hold the power button for at least a minute. This will discharge the phone circuit and clear out the RAM. Reinsert just the battery then turn on your phone. Try to turn on your phone.
If the phone still does not boot then connect it to a wall charger that is known to work and let it charge for 20 minutes. After 20 minutes try to turn on the phone with the charges still attached. If the phone is now able to boot properly then the issue could be caused by the battery not supplying the correct voltage to the device. Try replacing this battery and see if this resolves the problem. Another option to consider should the issue persists is to flash the CyanogenMod firmware again.
S4 Shuts Off On Its Own
Problem:My phone shut off on it’s own and now it will not turn back on. It had about 50% charge when this happened. I have removed the battery a couple of times. When I put it back in the phone vibrates like it is going to start up again but then it does nothing. I have tried to charge it and turn it back on. Nothing happens. Please help.
Solution: The first thing you should do in this case is to discharge the phone. Take out the battery and the microSD card ( if the phone has one installed) then press and hold the power button for at least a minute. This will discharge the phone circuit and clear out its RAM. Reinsert just the battery then check if the phone will now turn on. If it still doesn’t turn on then leave it charging with its wall charger for at least 20 minutes. If possible try to use a different charging cord. Check if the phone turns on with the charger still connected . If it does not turn on then I suggest you get a new battery then see if this resolves the issue.
If the phone still does not turn on even with a new battery then you should have the phone checked at an authorized service center as this could already be a hardware related problem.
S4 Switches Off Randomly
Problem:Hi. My galaxy s 4 started switching off randomly. I followed all tips found online but to no avail. At last , I took it to the technician and he said it could be the problem with power switch. He replaced power switch but the issue still persist. I can switch it on and it stays on for a few minutes and seconds and gets switched off. Technician said the problem could be motherboard now. I am not sure what to do. Please help.
Solution: Have you tried using a new battery on your phone? This is to eliminate any faulty battery related problems. You should also check if this problem is software related by backing up your phone data then doing a factory reset.
If the above factors have been eliminated then this could be caused by a faulty power IC on your phone. Have the technician check this out. It’s also possible that the motherboard is causing the problem.
S4 Switching On And Off Randomly
Problem:Phone started switching on and off randomly, then nothing at all, still had plenty of charge and holding charge, bought new battery, didn’t work, then when u hold the battery in on an angle it might pretend to try to turn on but doesn’t, (it vibrates then screen comes up and goes properly? please advise again) seems it isn’t contacting the terminals
Solution: It’s possible that this could already be a hardware related problem. Try connecting your phone to its wall charger then turn it on. If it turns on then I suggest you backup your phone data then do a factory reset. If it does not turn on then have the phone checked at an authorized service center. If you suspect that the phone battery terminal has a problem then have this checked first.
S4 Randomly Shutting Off
Problem: My phone keeps randomly shutting itself off. It usually happens after a notification appears on the lock screen but is not particular or consistent with one specific app. I have tried a soft reboot but it makes no difference. I have read your troubleshooting in regards to similar issues but this is different. It’s not battery related, it’s not app specific from what I can tell, and it’s not after an update. Any help would be greatly appreciated!
Solution: The best way to proceed in this case is to backup your phone data and do a factory reset. This way your phone starts fresh. After the reset do not install anything in your phone yet. Try to observe the device for at least a day if it still randomly turns off. If it doesn’t then the issue could be caused by a glitch in the phone software.
S4 Shuts Off
Problem:Playing talking Tom game when the phone shut off. When I turn it back on it will only stay on for a second then shuts back off. It has 45% on battery.
Solution: Try connecting the phone to its wall charger and let it charge for at least 20 minutes. Turn on your phone. If the issue still occurs then try getting a new battery.
S4 Does Not Turn On After Factory Reset
Problem:about a month after i got my phone, my mobile data stopped working. i brought it to the store and they did a factory reset but it didn’t change anything. now, 1 and a half years later, many apps started crashing. my phone would randomly freeze, and after a minute or two, a box would pop up saying something has stopped working. about a week before the crashes started happening, a box would pop up saying that it’s unable to detect my SIM card, and force me to restart. i have cleared the cache, then did a factory reset, but after the reset, my phone cant even turn on. i would press the power button, it would show the samsung logo and go to a bright screen with the at&t logo along with the blue LED light on the top left corner. Here is where it would freeze and can’t get to my lock screen
Solution: Try to check if the issue occurs with the phone connected to its wall charger. This is done to eliminate any problems that could be caused by a faulty battery. If the problem still persists then take out the battery and microSD card ( if your phone has one installed) then press and hold the power button for at least a minute. This will discharge the phone circuit and clear out its RAM. Reinsert just the battery then turn on your phone.
If the above troubleshooting steps fail then you should consider flashing your phone with its stock firmware as its software could already be corrupt. You will need a copy of your phone firmware file as well as a software called Odin installed in your computer. Detailed instructions on how to perform this procedure can be found at several of the popular Android forums online.
