Yes many people have used the Super sume app before on 5.1.1 including me. And I have used the script several my Stylo and Leon.

I meant if anyone has tried it on MM.

But from the sounds of it this version of Kingroot is having its problems on our device.

Ok, so ive installed the 15 second program to install fast boot and adb system wide. I have an adb application in C:/adb i have a fastboot file in the same folder. Yet when i try to "fastboot adb devices, i get nothing. Ive been trying to figure this out for 2 days. Ive installed android studio, sdk, minimal adb and fastboot, drivers, and the 15 second adb fastboot installer. What do i do? More importantly, how do i install fast boot if its supposed to be installed already. I am at my wits end here, but would really like to be able to enjoy MM with root. Anyones help would be highly appreciated. Thank you.

I dont know if it matters but i uninstalled minimal adb and just installed the 15 second program it also didnt want to work. and i also just opened the cmd program in the c:/adb folder holding the shift key and right click and select open command window here

I tried that too and it didnt work. When i plug my phone in, i verify the usb debugging toast. I think that when my phone reboots to fastbootmode, something is going wrong. Ive tried every adb fast boot app i could find. All to no avail. Once in fastboot mode, if i type adb devices again, my phone doesnt come up in the terminal. I just have absolutely no clue as what to do. I am beyond frustrated, to the point where im just about done. No matter what i do, no matter how many times i try, i cannot get my device to be recognised by my pc once in fastboot, which means i cannot acheive root.

Are you absolutely sure your device drivers are installed correctly? Not adb or fast boot drivers, but device drivers?

Jack Mickey · Mar 21, 2016

@TMacgnolia , if you can find the time to explain to me how i can fix this, id be highly grateful.

joethe 1 · Mar 21, 2016

did you try revoke usb debugging authorizations and plug your phone back to your computer and let it ask u again

joethe 1 · Mar 21, 2016

Jack mickey I'm not seeing where it ask to "fastboot adb devices" in the instructions also

Jack Mickey · Mar 21, 2016

I have. My issue is as soon as my phone reboots to fastboot mode( on the lg splash screen) it loses connection to my pc. From here, all i can do is a battery pull. Here are the steps i took. Revoke usb authorizations, enable usb debugging. Plug in. My phone asks if it want me to connect my data to my pc. I hit yes. The toast for usb debugging pops up. I allow. I go to C:/adb. In this folder i shift right click. In command i type adb devices. My phone comes up. I type fast boot devices, nothing. I type adb reboot bootloader. My phone reboots to fastboot mode(LG splash screen). During reboot i hear my phone disconnect and reconnect to pc. My phone stays in fastboot, and NO command in terminal does anything to it. If i type adb devices again, nothing comes up.

Jack Mickey · Mar 21, 2016

@Blu8 , ive tried installing the drivers for my device 5-10 times. Each time my pc says lg drivers installed successfully. How exactly do i properly install the drivers if i havent done so already. This is the only thing i can think of that i may be doing wrong.

joethe 1 · Mar 21, 2016

when you typed fastboot its one word on your post you put it as two words is this a typo

Jack Mickey · Mar 21, 2016

I do this to the Tee. Once i reboot bootloader, my device boots to fastboot mode. (lg splash screen). If i type fastboot devices, nothing.

Jack Mickey · Mar 21, 2016

Once i try to oem unlock, terminal just states "waiting on device" all i can do on my phones end is a battery pull.

joethe 1 · Mar 21, 2016

thats all i know sorry couldnt help more

Jack Mickey · Mar 21, 2016

@joethe 1 , no. It was just a typo in the post. Lol darn spell check

Jack Mickey · Mar 21, 2016

Here is what im gonna do. Factory reset my phone, install drivers, adb and fastboot to a different pc. And then follow the guide. If it doesnt work, well i wont know what else to do.

Telyx · Mar 21, 2016

When you type "adb reboot bootloader" and the phone boots, make sure you type "fastboot devices" and not "adb devices." That said, when I tried this with adb in Windows, "adb devices" always said my phone was offline even after revoking debugging permissions and reaccepting the key. Tried it in Linux (Mint 17) and it worked perfectly.

HallOfPromise · Mar 21, 2016

Is it still possible to unlock the OEM in the dev settings or is it required to do it via fastboot?

Telyx · Mar 21, 2016

On the phone you can allow unlocking the bootloader, which doesn't actually unlock it. I believe you need fastboot to unlock the bootloader.

Blu8 · Mar 21, 2016

Either way works I'm pretty sure

Telyx · Mar 21, 2016

Checking "Allow OEM Unlock" in Developer Options doesn't unlock the bootloader. I had that checked when I tried booting TWRP in fastboot and got an error message saying I had to OEM unlock in order to boot a custom recovery. Once I did, I could boot TWRP. It's like a Nexus--you have to fastboot OEM unlock to use a custom recovery.

Blu8 · Mar 21, 2016

Alright, now it's like that. Back in lollipop that check sufficed. Good to know though.

HallOfPromise · Mar 21, 2016

Damn! I was hoping it would carry over to MM. Looks like I will need a computer to get this done. Kingroot doesn't seem to be fully successful and OEM unlock can only be done in fastboot, from the sounds of it. I can get it done, I just need to make sure my computer won't crap out like it did the last time I did this (upgrading to 10L).

Telyx · Mar 21, 2016

I think the bootloader was already unlocked in the Stylo on LP and the MM update locked it (but gave us adb & fastboot capability).

I truly do not understand why you are having so much trouble with fastboot unless it is a driver issue. When you install your drivers for your device make sure your device is connected to your computer ass this does make a difference
Also try installing the drivers while your device is connected in fastboot mode. Wish I had more advice than that.

I did not test this but I feel like we could do the fastboot oem unlock in 5.1.1 as well. I think the Enable OEM unlock in developer options only unlocks the system, boot, and recovery partitions and allows booting of none factory imgs that are installed to one of these partitions. I think the fastboot oem unlock unlocks all the partitions and allows use of all fastboot commands.
