Hello everyone, I hope you are all fine.
I just brought an S4 2 days ago, and I was forced to Root it using Odin.
The process went well I had my phone rooted and working Fine,Until today when I was listening to music in my phone, and I wanted to turn down the Volume a little bit, but the Volume down button didn't work !!!( it's not a hardware probleme because it was working perfect this morning, but after I gave the phone to my lil sis she had done something in the settings I thinks), so after that I tried to turn off my phone to see if the volume button will work(it was the first time I shut down the phone after the root),and then an error showed up with a yellow triangle on the bottom of the screen, the error message is ''Warning!! A custom OS can cause a critical problems in your phone and installed applications. If you want download a custom os press the volume up key. Overwise, press Down key to cancel. Volume up : continue Volume down cancel ( restart phone) '' . I tried to press both Volume buttons but it didn't work, so I tried to shut it down again and press volume up buton +home+ power button then the phone turned on with the Samsung galaxy S4 screen I was so happy but when it did turn on it was On safe mode -_- , right now I can't flash the room because I can't press the Volum Up button to Continue to Download mode, Right now I'm still at safe mode and waiting for your ideas , Please help me guys I'm new in this Forum a friend of mine told me to post here and they will help you.So please help me.
So you're no longer stuck in download mode but are in safe mode. Power off the S4 and turn it back on. If safe mode reappears then your volume down button is stuck. [EDIT] If you cannot enter download mode, your volume up button is stuck. Exchange the S4 for another unit if possible. If not possible, whack the left edge gently against a table to try and unstick the button. If that doesn't work the button on the motherboard needs to be replaced.
Problem: Power button is not working on my D800. It doesnt turn on or off when I try to click on it. If the phone is off, the only way to turn it back on is plug in the USB. However, the phone still reset if I hold it for like 10sec. I can't get into recovery by holding the power button and down.
History: The phone was recently bricked into qhsusb_bulk mode. I followed the instructions on this board and re flashed some files. I think this is when the power button stopped working. After that I used LG Flash tool to restore to stock 4.4.2.
If anyone can help, I would very appreciate.
plzzzz help mee
Hello everyone
lately i entered to recovery mode through adb but my power button is not working and when i remove the battery and plug it in and turn on the phone trough the charger and the battery it keep booting to recovery mode is there any way to get out of recovery mode without using the power button your help is really appreciated
Doesn't the recovery have a reboot option?
In case, your volume up button might also be stuck. The device can't enter recovery just with the power button.
Either that, or your OS is messed up.
I used adb terminal and enter it by mistake and my volumes button is working but the power button is not
Hi Masters,
Need your advice here.
My p9 lite cannot boot up and only shows your device is booting now screen.
I cannot power off even force power off, and there is no responding whatever key combinations i pushed.
The step taken to this error is I did unlock my p9 lite and tried to flash twrp by following the guide, then I cannot enter fastboot mode and recovery mode after that.
I tried take out the battery and let the phone disconnect with power supply, after i put back the battery, i push the power key it still shows same screen as your device is booting now.
Any idea how to resolve this? I assume some fatal error with the motherboard, but i can say nothing after i unlock the phone.
Your suggestion and advice are much appreciateļ¼ thank you!
I had the same problem,what I did was force power off by holding power button for ,well idk how long but until device booted down,then I held volume down and connected it to pc,so it enters fastboot,but you have to do it fast,as it will reboot once its turned off.Then I tried various twrps,revolution recovery etc,and the only one that worked was meticulus twrp.I know you said you cant force power off,but try holding power key long
Once you hold the power off button, the phone will never power off, instead, the phone will reboot and bring you to the error page "your device is booting now" and stuck there. I tried to push the power up or power down button before i see huawei logo, but it will show me the same page.
Yes,when you hold power off phone will reboot,and you have to be fast with volume down and cable.Pre-plug the cable it computer ,bring it near phone,power off and before it boots plug it in while holding volume-
thank you for your suggestion. I tried many times, no matter how quickly i am, I only able to see the device booting page. I have mentioned one point above, i did take out the battery, and i see the error screen after i put back the battery, so i assume the problem with motherboard.
How many of you did return the faulty and unlocked phone to service centre then get "free" services?
