Hi, I've tried many times to root my Vodafone Smart Prime 7 Marshmallow (VFD 600) with Android 6.0.1, but just can't find out a working method to do it. I've tried almost every one-click-rooting apps, such as Kingroot, Towelroot or Wondershare's Mr. Fone for my Windows, but none seems to work. They all say that root for my device is still unavailable. I also tried the Poot+Ministro method, with different versions of Ministro, but still keep receiving errors such as "Invalid qt version" or "Ministro can not satisfy your application dependencies". Can you help me out step by step? I'm new on the field, so I still have little knowledge of rooting. Thanks.
Up, please help! I've been trying for about a week now, and still can't figure out how to do it. In the meantime I also tried ADB+Fastboot, installed all drivers properly, both ADB and Fastboot recognize my device as connected with "ADB/Fastboot devices" commands, but any other Fastboot command refuses to work. I always end up getting the error "FAILED: [remote: unknown command]". What should I do? I have both Debug USB and Allow OEM Unlock enabled in Developer Settings. I think I should unlock the bootloader, but can't make "fastboot oem unlock" work. Any help please? Also, is it normal that in bootloader mode it gets stuck on "powered by Android" screen?

Having trouble rooting my LG K40. I have the same problem as this person when trying to boot into fastmode: https:// youtu.be/yQ99lQv0rQk?t=26
You can find his post here explaining the process more in detail: https:// lgk20.com/root-lg-k40-lm-x420-bootloader-unlock-twrp/
MODEL #: LM-X420MM
Any help is appreciated,
Thanks in advance.
im having the same problem. i must have a proclivity towards phones with what seems impossible rooting methods. the first was the samsung j7 prime and now the lg k40 lmx420mm. ive gotten as for as adb reboot-bootloader, just restarts device, fastboot commands are either not recognized or i receive "waiting on device". Ive updated drivers, followed a diff. method found on reddit posted by jamesrascal (i cant post url here because of my newb status). Phone just stays stuck in firmware update. i feel as if ive exhausted all resources, any direction or help would be appreciated, im not educated on rooting ive been successful a few times on other phones and jailbroken some iphones, im mostly doing this to learn and teach myself so it isnt urgent but i need help to continue any further. thank you
Same problem for me. Because the device has good value for the money it would be nice someone can help us here.
Further this device seems to be full android treble conform I like to know how benefit from this circomstance.
I have LG K40 LM-X420EMW with dualsim.
Thanks for every hint!

IIRC an Android user can not unlock the bootloader without first OEM unlocking, because without this process the device will not accept the bootloader unlocking command.

OK, but it is not possible to get into fastboot mode to enable the OEM unlocking. I marked the slider in developer option butz still there is no chance to get in fastboot mode.
After command "adb reboot bootloader" the device always reboots in normal system mode.
@baerenbisch
Once you enabled the OEM unlock on your Android, the “unlock ability” flag is set to 1, which allows you to use the
Code:
fastboot flashing unlock
command what unlocks device's bootloader.
BTW: Once you have enabled OEM unlock, it stays on. Even if you do a factory reset, it stays unlocked until the setting is manually altered again by going into the Developer options section.

Hm,
may be it is "allowed" to unlock but in the "LG K40 (LM-X420EMW) real world" it is not possible.
You dont reach fastboot mode which could enable using the order you proposed.
Device reboots into standard mode instead of wanted fastboot mode after sending "adb reboot bootloader"
I think thats the problem.
Code:
[email protected]:/# adb devices
List of devices attached
LMX4205P4TU4S4HEOJ device
[email protected]:/# adb reboot bootloader
[email protected]:/# fastboot flashing unlock

Temp root does sound nice, but what can you actually do with it. Can you change the OEM unlock key?

Hello guys, recently I bought Chinese AllCall Madrid phone. I was searching for twrp port for that phone and I have found it on {MOD EDIT: reference to warez site} forum, only twrp for this phone on internet. I tried to flash it using flash tool it failed(flashing stock rom fails too), then I rebooted to fastboot to OEM unlock and no OEM unlock is available, output is remote failed unknown command, ofc I enabled OEM unlock developer options.. I managed to use mtk-su exploit to gain root, and I can run adb and apps with root permission. My real question is has anyone unlocked this phone? If yes pm me please :laugh:
@Mr nobody 1312
Assuming you want to unlock the bootloader.
IMO before trying to unlock a device's bootloader it's always a good idea to check by means of ADB whether unlocking the bootloader is natively supported on device:
Code:
adb shell "getprop ro.oem_unlock_supported"
If returned value is 1, then it's supported otherwise it's not.
If it's supported then you run
Code:
fastboot flashing unlock
to unlock the bootloader.
Yeah output is 1 but no OEM command is found in lk.bin I decompiled it, they locked it to push their malware I have found addups fota malware and virus in helper apk, anyway is it possible to crack bootloader with custom lk.bin, where I should look for exoloitable bugs? Is there any freaking way to crack it?
Hello,
I've been trying to Root my Samsung C7 SM-C7000 phone but I keep getting the error that my phone is factory locked.
Is there a way to overcome this or unlock the phone?
I have read some threads about Enabling OEM Unlock in Developer Options, unfortunately this OEM Unlock is not available in my Developer Options menu no matter how much I tried getting it available by resetting dates.. etc.
Can anyone please help?
Can anyone help regarding this matter please??

If option OEM unlock isn't offered in Developer options then phone's boot-loader can't get unlocked: Live with it.
Is it confirmed that OEM unlocking cannot be turned on on my device?
It's Samsung Galaxy C7 SM-C7000
Only to have said it: To root device's Android ( Android 6.0.1 ? ) it's not a prerequisite that phone's boot-loader got unlocked before.
The software on it is Android 8.0.0
I have tried to Root it and it said Factory locked.

You probably did it the wrong way.
Well in the download mode it shows me "Installation Failure" and under it
"You need to unlock your device to install a custom OS"
"For more information how to unlock visit samsung.com/cn"
I have even tried Rooting by going through recovery mode then selecting Reboot into Boot-loader, Same error.
@KHAWaNAWA
Look inside here.
Tried that too, same error still, phone is locked.
