Hi, i have a rooted SPH-M840 (Galaxy Prevail 2) and when my phone boots up it displays the message "shell has been granted Superuser permissions" and everything freezes (time doesnt change, superuser notification stays on screen) except the blinking cursor in the password box. also the low storage icon appears in the notification bar. while its in this state, the hardware buttons do not work and once you either press somewhere on the screen or press the volume button the cursor stops blinking and freezes completely. i can still soft reboot with the power button after its frozen but that's all i can do. i have tried two solutions which have failed to work but i need suggestions as to what i should do. i have tried hard rebooting but when it gets to the second boot logo and the message "boot to recovery mode by key" displays, it never goes to the recovery mode menu and shuts itself off. another method i have tried is going into my phones files by connecting it to my computer and either disabling superuser or deleting some files if storage was the issue, but when i connect it to my computer i cannot access the files because it says i need to troubleshoot my device. when i troubleshoot it says i need to install a driver fro my phone, when i accept the download, the download fails and there are no further options. I should mention this has happened before but the first time it only acted like this for 3 days and returned to its normal functioning state by itself but this time it has been 6 days and im looking for a solution. any help?
Hello, and welcome to XDA Assist! It seems to me that the best solution would be to reflash stock firmware and start afresh. But you might want to post your question first to this thread: [HELP THREAD] Ask ANY Question. Noob Friendly. You will need to register in order to post.
Good luck!

I tried factory reset and still got the same problem. service center told me that i have to pay 210 euros and that the root caused the problem..
Hello World.
I got this black screen with red and blue flashing LED after i tried to do a TWRP.
Mainly, people get this because they got the wrong .img for their phone. I live in Quebec with Koodo and i used the D852 wich I'm pretty sure is the correct one for my phone.
At 1st, i was using the command prompt method to install TWRP.
From that, I got the LEDs but i was able to boot the phone after pressing volume down + power.
So because that didnt work, I used an app called flashify.
From that, I got the LEDs but I can't boot the phone anymore, doesnt work when i try to factory reset it, I get a message in the top left saying boot error.
Please help me! I just want to install Pure unchanged android 5.0 like nexus users
PLEASE HELP :'( Can't use my phone anymore

Hi,
The problem I have is really very common to most Samsung Galaxy users, but I haven't found any solution to my particular problem. Well, basically my Samsung Galaxy won't get out of bootloop. It just won't go beyond Samsung Galaxy SIV I9500 screen. The phone never did this before this. The phone did, however, rebooted occasionally by itself when running normally.
My phone is rooted, but it runs the official version of Lollipop for Galaxy S4. I had to factory reset my phone one day, and I decided it to reset from the Recovery Mode. After successfully resetting the phone, it booted as usual. Soon after it suddenly turned off, and went into this complete bootloop and would not stop until I remove the battery. Whenever I insert the battery back in, the phone starts by itself, without me pressing any button, and goes in the bootloop again. I can only enter the Download Mode that too for a couple of seconds. When entering the download mode I don't have to press the power button.
Is there any solution to this? I am assuming that my power button suddenly failed. The power button is definitely not stuck. I have opened the entire phone and cleaned the motherboard, and rechecked, it still showed the same problem.
Really appreciate any kind of help.

Really appreciate the prompt reply. My bad, sorry. Not quite familiar with XDA Forums. I have posted a similar question there. We should end this thread.

Very new to this but I finally got my g pad rooted. Now when I try and flash a rom it just goes to the lg screen and displays the error mentioned in the title. When I try to manually enter the recovery menu via the volume and power keys it only goes to a factory reset screen with no way around it. Any help would be appreciated.

Hi, Thanks for using XDA assist
It looks like there is no dedicated forum for your device, however
There is a general forum for android here http://forum.xda-developers.com/android/help where you can try to ask to get expert's help.
Good luck.
Before you read my problem plz note that i am only 16 and i have very little knowledge about anything related to rooting.
I rooted my phone a month ago because i wanted to use Xmod for Clash of Clans. I tried using Kingroot but it didnt work so i installed TWRP using Odin through my pc. After that i flashed SuperSU and the phone got rooted.
I didnt want xmod anymore so i decided to unroot my phone. I wanted to install the stock recovery and i read that i can do this by flashing the recovery.img file using Flashfy. So when i flashed it the app said that i need to reboot my device. So i pressed reboot and the screen went blank. But it didnt reboot. The screen that says Samsung Galaxy J7, which comes whenever i reboot or restart my phone, shows up but doesnt change. It also says "recovery is not seandroid enforcing" on top of the screen. It started coming when i installed TWRP. Nothing happened when i long pressed the power button. So i took out the battery, put it back and did 3 things:
1) Switching it on using the power button,
2) Directly going to recovery, and
3) Putting it for charging without switching it on.
The same screen comes everytime. PLEASE tell me what has gone wrong as soon as possible and if there is a way to fix this. Thanks a lot in advance.
