Some way to root Lenovo Vibe B? - Android Q&A, Help & Troubleshooting

I was trying many ways to root my Lenovo Vibe B
but didn't work
if someone knows a way to do that please help me

There is currently no way to root it with twrp + supersu or any other open-source project. A Google search indicates that the application "King Root" does the job, though I would not trust it. There are twr and supersup builds for similar models, you could get one of those and try to build for your phone. That being said twrp is a complete mess of a project, documentation is simply nonexistant or in the form of poorly written "tutorials" in this forum, and supersu seems to be organized in this mess of a forum so I'm not sure I'd trust them either.

Hey, do you speak spanish? I've rooted my Vibe B (A2016b30 model), where did you bought yours? Maybe the files I have could work, also I have a PDF step-by-step tutorial, but is in spanish. It worked great.

I found this on Youtube, it looks like it involves flashing a hacked bootloader (although it seems to be for the dual SIM version) https://www.youtube.com/watch?v=8aLpy1qbn8s
I've done a Google translation on the instructions:
In the cell phone:
1. Activate the "Programmer Options" menu in "Settings / About Device / Build Number". (Press 7 times until the message "No need, you're a programmer.
2. Enable the "OEM Unlock" and "USB Debugging" options in "Settings / Programmer Options".
In the PC:
1. Connect the cell phone to the PC.
2. Install the file "Lenovo_USB_Driver_1.1.34_Setup.exe".
3. Open the "ADB_START.exe" file that is inside the "ADB" folder, a console will open.
4. The phone will display a message, just select the "Always allow from this computer" box and "OK".
5. Type: adb devices, it will display a list of connected devices.
6. Type: adb reboot-bootloader (The cell phone will display a small message)
7. Write: fastboot oem unlock (In the phone it will show a small menu in which you have to select "yes" with the "volume +" key)
8. Write: fastboot flash boot boot.img (Once the startup flashing is finished, the battery will have to be removed from the phone for 3 seconds and then re-set to restart the phone)
9. The cell phone will be returned to its initial factory state so the first Android startup will have to be configured and connected to the PC to copy the file "SR4-SuperSU-v2.78-SR4.zip" to the internal memory of the And then turn off the phone.
10. Turn on the cell phone by pressing the "volume +" key and the "power" key in "FASTBOOT" mode (Selecting with "volume +" and accepting with "volume -
11. Write: fastboot flash recovery recovery.img (On the screen of the cell should appear something like this: "USB Transferring ... USB Transmission OK Time: XXXXms Ve1: 10154KB / s")
12. Once the process is finished, remove the battery, replace it and switch on the cell phone by pressing the "+" key and the "power" key in the "RECOVERY" mode (selecting with "volume +" and accepting with "volume - )
13. Start the TWRP, select the "Never show this screen during boot again" box, select the corresponding language and slide the blue bar at the bottom.
14. Press the "Install" option, select the file "SR4-SuperSL1-v2.78-SR4.zip" and slide the blue bar at the bottom.
15. Wait until you finish installing and finally reboot the phone, Done.

Thanks for posting the instructions.
I got my a40 (dual-sim) with fw S219, upgraded to S235, then unlocked it.
For whatever reason, I could not "fastboot boot twrp.img", so I had to actually install it (not having a backup of the stock recovery, this made me a bit uneasy). "adb shell 'su -c id'" confirmed that rooting had succeeded.
Thanks to all involved in this success!
