Boot Loop On Reboot After Successful Root (With KingoRoot & KingRoot) - Galaxy Grand Prime Q&A, Help & Troubleshooting

I first tried to root my Samsung Grand Prime (SM-G530W) a while back using KingRoot and it succeeded, but after restarted my device it got stuck in a boot loop and eventually showed the "Custom binary blocked by FRP lock" error, but after factory resetting it everything was fine again. Now, I tried to root my phone again using KingoRoot this time, once again it was successful, but now it's stuck in another boot loop and there is no error message. I tried booting into recovery mode and factory resetting, but the problem still occurs. What can I do???

You need to flash officiaal firmaware and flash it with odin

Did u enabled USB debug mode on developer settings? Flash stock firmware via Odin and never try install superSU via KingoRoot. Or find another way how to root.
Try this: https://www.skyneel.com/root-samsung-galaxy-grand-prime-sm-g530w

Enable OEM unlock in development setting :good:

Problem solved
I just flashed it with official firmware using Samsung Kies 3 :good:. This video helped me figure it out:

Boot to recovery & factory reset / clear caches
Actually my phone is stuck in recovery and unable log in recovery mode. I think problem is in the boot loader. Because if i flash any custom recovery odin shows success but there is no change in the knox counter.

Samsung S4 wont stuck in boot

So ive rooted my phone in the past and flashed custom roms(downloaded from samobile).I used triangle away to trick the phone that I was not rooted. I began upgrade process in kies. All went well, but root was gone and supersu didn't work so I uninstalled it. I then decided to root with kingo root. All went well again(root succeeded). Here is where the problem starts: when the device rebooted it shows Samsung logo with these little lights flashing around the logo. I left the phone to boot but 1 hour later its stuck in the same position. I thought it was a boot loop but I accessed recovery and wiped cache partion. Still nothing. I went to recovery again and did factory reset. Still nothing help me please guys.

Issues when Rooting S7 Edge, wont enter Recovery, HELP!

Hi!
Ive tried to root my phone for the whole day without any success.
First time i rooted it (successfully) i forgot to check the OEM unBlock in Developer tools, so i had to re-flash the stock Rom to be able to boot it.
then when i enable the OEM Unblock in Developer Tools, i shut off my phone and go into "Download Mode".
Im using the "CF-Auto-Root-hero2lte-hero2ltexx-smg935f" to root the device.
It goes so far as it reboots, then when it tries to enter Recovery Mode to finish the Rooting it gives me the message: "recovery is not seandroid enforcing"
Suddenly im unable to enter Recovery Mode.
To solve this, i yet again re-Flash the Stock Rom to be able to both Boot and to be able to enter the Recovery Mode.
And this is the Loop im stuck in.
Whenever i try to Root, it wont let me into Recovery, and whenever i try to fix it im back at Stock Rom again.
Please Help me, what do i do, and what am i doing wrong?!
Ps. Already checked so i got Exynos Chipset, so it should be able to root?!
What you did wrong was that you didn't let the root process finish. You see "recovery is not seandroid enforcing" and panic but actually you should wait for it for at least 5 minutes as chainfire(op) said himself in CF auto root thread.

How to root my phone?

'Encryption Failed, unable to start up your device' after flashing with Odin

I have a Samsung S7 Edge that kept rebooting itself randomly. I thought it might be due to a corrupt update. As time went by it started to bootloop several times before booting properly.
I managed to remove my Google account to disable FRP but I didn't manage to activate the secure startup pin before flashing.
Used Odin 3.14.4 and downloaded the BTU version of the firmware, but I later realised that the version used was XEU. Does that matter at all? Once the flash completes it auto reboots and begins bootlooping again. I have tried to clear cache partition and also factory reset via recovery menu. It again starts bootlooping many times, until it reaches the following screen that says;
Encryption failed. Unable to start up your device. The encryption process was interrupted. You need to reset your device to factory default settings. This will erase all your data. [Reset].

What else can I do here? I have not tried changing any settings in Odin, I left it at its defaults.
I am also unable to flash TWRP, as I understand I would need to unlock the bootloader beforehand and I'm not able to get it to boot.
Any luck? Its too late though

Bootloop after updating magisk

I have an asus zenfone 2 laser running android lollipop. I have turned the USB debugging on for my laptop.
I used to install kingoroot for rooting my phone, and it works fine.
For no particular reasons, i switched over to magisk and uninstalled the kingoroot apps.
The installation was successful, then the app asked me to update it via the app. I updated it, and then it asked me to do reboot.
I rebooted............and i got stuck in bootloop.
I got into the recovery mode and factory resetted the phone but i am still stuck with the bootloop.
I tried to install magisk uninstaller zip from sd card but the installation was unsuccessful
I tried to install the latest firmware from ASUS's official website from SD card and was unsuccessful
I tried to flash the latest TWRP to my device via flashboot. Since many tutorials out there have a TWRP Recovery mode to fix the problem which i don't hace at the time. i used "fastboot flash recovery TWRP.img" command and it said finish.
But it lead me to a new problem. I cannot use "power button+vol.down" key combination to access stock recovery mode. And the TWRP recovery mode doesn't come out as well.
One thing that i can use is the "power button+vol.up" key to access fastboot mode..
I stopped messing around with my devices for now so that i don't make the problems worse. I hope someone can help me out with this problem
BIG THANKS
