Actually the post you linked doesn't include the bootloader unlocking instructions and on the next page someone says it's not needed but I assume I have to do it with the standard command. Also will this wipe everything because my plan was to install TWRP and back up everything before continuing

Quoted from the link I sent you:
"3. Enable OEM unlock (Settings> Developer> Unlock OEM)"

I agree, it's not very clear, but they mean the bootloader by this. There should be an option called "Unlock OEM" or "Unlock Bootloader", I can't remember which one exactly, but you have to check that one.

And yes, the wipe option in TWRP will wipe everything.
I recommend using "Advanced Wipe", then check everything except SD-Card and USB-OTG.

Before you wipe everything however you can make a backup with a build-in tool in TWRP.

Here you can read how it works: https://www.howtogeek.com/240582/how-to-back-up-and-restore-your-android-phone-with-twrp/


Good luck!

Please ignore such kind of people, they are rude and uneducated and in all probability do not have a ghost of an idea about what they are doing here.

enable oem unlock in developer settings. reboot to bootloader.
then open fastboot and run

fastboot oem unlock

your data will be wiped.
place twrp img into adb fastboot folder and run

fastboot flash recovery <twrp image name>

Hello,
I have tried everything on the in the forum, but still can't flash TWRP recovery on my phone. The phone is rooted and if i do it through the app that is on the google play store, booting in to recovery gives only black screen and can't do anything else. The only way is to take out the battery. If i try to do it through the abd fastboot option it gives me that fastboot is locked and when i try to unlock oem it says it is not allowed.
Also i have tried it with a a6020a40 stock rom ( i can flash TWRP recovery), but it is for dual sim card phones and my phone has only one sim card so i have no signal (radio turned off).
Thanks in advance.

What model and hw number do you have?
I have a41 and had the same thing.
If you have an SD415 then go to K5 (non-plus) forum and find the tutorial i made for locked bootloaders.
If you've got an SD616 then you're out of luck. Only thing you've got is a vibeui marshmallow port (again, by me) for locked BLs.

Infact, if you find a way to sign boot and recovery images, then you've got a chance.

Ok i did some googling about that and it is just to much for me to understand, just going to stick with the stock rom.

Yes, that's over me too.

Know what, someone did flash wrong bootloader file and hardbricked his phone. He sent it to repair, and those repairmen replaced his mobo. the phone was sent to service with SD616, and returned with SD415. Then he unlocked the BL.

Not tryna saying to do that or to give false hopes, but what's happened is real afaik.

That one way to do it, but i also read on the lenovo forums that you can ask your services provider to unlock fastboot if they would like, or ask lenovo to send you some code to unlock the oem. I don't like my services provider (not the smartest people, at least where i am), and it could be a hole process, i don't feel like asking them.

@333vasc, you know what?
Go to a file explorer and see what is the TWRP img file size. a few kb right? because you surely had downloaded it from a common browser.
That is what you flashed. A corrupt file.
SAME happened to me a few moments ago, trying to update to the latest version.
I flashed and got an endless lenovo logo.

Solution: Download the file with a download manager, like ADM, the one what I use.
Final img size should be around 15 MB.
Flash it and enjoy the life.

The TWRP file is 15mb. Using qfli i installed another rom, not for my phone but a similar and it worked on that, TWRP recovery worked. The problem whit that was that the rom was for a dual sim phone, and my phone is singal sim so i couldn't get any services.

A6020a41 devices have bootloader unlock bug, unlike other variants. European phones with SD415 are identical to Indian a40 sd415 so flashing their firmware works. Since there is no K5 phones with single sim, 720 screen and sd616 soc except a41, there is no firmware to flash to unlock it properly.
@333vasc you have a41, right? I hope I'm not mistaken.

Yes that's the specifications for my phone, a european version K5, single sim, sd616 and a41 firmware. Thank you for taking the time to explain this.
