No

You have to unlock the bootloader. I have same phone and have not been able to find a working process yet. Good luck, please post if find anything.

Has no one found a way to do this yet? I have Sprint Variant. Switched away from sprint so this phone is essentially being used as an extra android device.

Unfortunately, system.dev has stopped.

Hi all. I have LG-F160 and on the display "Unfortunately, system.dev has stopped" so i can't do anything on my phone. What should I do???
Hello. Have you found a solution? What did you to to get this error? Have you fixed it? My LG G2 has the same error.

Have you tried to flash it? Does your device has USB Debugging enabled? My has not, I can't enabled with that Notice showing up everytime!! Any help?
SOLVED! (G2)
Hey! I solved this problem on my unrooted G2 by managing to skip the notice (be very quick) and installing TowelRoot, then AutoRec, Then flashing CloudyG2 from the recovery and done, no more such an error!
And I converted my G2 into a G3 just at the same time
Very easy. I guess you can try flashing a KDZ in download mode or the LG support tool, too.
Cheers.

i can't able to use my tablet now, because its always unfortunately dev has stopped. please help me to fix it.

How to remove EncroChat OS on my Oneplus X ?!?!

Hi there , I have a Oneplus x. It had been remote wiped but still has some strange difficult software. Posted this problem to the Oneplus Forum but have had no response, thought XDA would be more qualified!
From what I can tell it's a Oneplus x with the software on the phone with a high-security version of Android. It's called EncroChat and from their website (encrochat.network or encrochatsure.com) it looks like it removes the recovery from the phone and replaces it with an EncroChat OS (some kind of Cyanogen) that you can boot to in addition to the Android OS.
Well I assume during the remote wipe something went wrong with the software and the phone no longer really functions. It boots up fine but can't connect to Wifi, cellular, not detected when connected to my PC, and has no real apps to speak of. I think most of the device's drivers are missing. Trying to boot to recovery instead boots to their EncroChat OS which is locked behind a password (wich I have) but anyway you can do nothing in it.(no wip, no factory reset)
I can get to fastboot and my PC will detect the phone then but running the bootloader unlock command doesn't work, the phone just reboots into the locked EncroChat OS. My idea now is to try and hardbrick the phone and then re-do everything on the phone over again, but I can't figure out how to do that. Does anyone else have any ideas?
If the bootloader is locked, you wouldn't be able to flash a custom recovery. But there's a special recovery software for Snapdragon chipsets, I'll look up for the link and LYK

1. hold the 'power'+'volumeUP' buttons until you get into recovery mode
2. once in recovery mode, go to and select 'Reboot to bootloader'
3. when the 'Fastboot mode' message appears at the bottom of the screen, plug in the USB-A male to male cable to the PC
4. if you have your device manager open, you will notice that it is recognized as 'Android Phone'/'Android Sooner Single ADB Interface"
i tried rooting with three different 'one-click root' pc applications: iRoot(v1.8.8), Kingoroot(v1.5.0), and King Root(v3.5)
these are the results i got:
-iRoot: it connects but the message reads 'Not support mode'
-Kingroot: it detects the device and trys to connect but gets stuck in a loop trying to connect
-Kingoroot: this detects the device as 'HTC Device'. i click the 'Root' button and it trys to root, but it only gets to 19% and then it fails
i'm theorizing that maybe if i get some different drivers for the pc or maybe making sure that the 'one-click root' applications are the latest versions might help. i dont know, we'll see.
again this is for the RCA RCT6303W87M7 running Android 6.0.
if anyone tries this and has more success, please let me know.
so to update on this, updated and installed the latest versions of the 'one-click root' applications and got the same results as before. let me know if anyone else tried this.
this is for RCA Viking Pro, model RCT6303W87M7, Android 6.0

I have not rooted anything without a how-to. Prehaps someplace there is a how-to to do this but this is what makes sense to me:
My New Motivation:
At this point my issue is that the unit has not had any updates including security since i purchased it. I really expect more and it's to the point where I feel it might actually be more secure rooted than not.
Originally
I just searched , saw it could not be rooted easily and was like whatever.
Ideas about how to get started
Get the adb tools working and using those get as much information from the prompt as possible without root and share it all.
If factory ROM images are around or can be backed up from device then prehaps a disassembly of the ROM images and examination of settings files will reveal any interrupt hooks for getting root that are as of yet undiscovered.
Gleaning any information from online sources .. prehaps a tear down of the unit, we need to find the most similar models to this model family.
See if there is any information available from the OEM. Determine who did the Android build. ....
What do you think?
