go into settings / general / about phone / software info / and click model number 10 or so times to unlock developer options. you will now find it under settings / general / developer options. you will want to check the enable OEM lock tab. you now have an unlocked bootloader and can access recovery from any app.
[LG Leon Questions & Answers] oldsysop:
Not "OEM lock tab" in H340
[LG Leon Questions & Answers] LuciIT:
It exists if you upgrade to 6.0 Marshmallow, but is useless because we can't access bootloader or fastboot mode to flash twrp without root which is unavailable via one-click root methods.

ROOT AND TWRP

HOW TO ACTIVATE USB DEBUGGING

1. Activate the Developer options (Settings> About phone> Device Information> to tap 7 times in Build number)

2. Enable USB debugging (Settings> Developer> USB Debugging)

3. Enable OEM unlock (Settings> Developer> Unlock OEM)

4. Connect the phone with the USB cable to the computer

5. Install the drivers that come on the CD cell partition.

TWRP:

Download TWRP from HERE or TWRP WITH EFS BACKUP AND MORE

Copy it to the folder where abd is installed.

On working adb, type in these commands

adb reboot bootloader
fastboot flash recovery LenovoA6020_TWRP-3.0.2-r3_7M.img

OR

fastboot flash recovery TWRP-k5-3.0.2-r2_shreps.img

This will permenantly flash twrp instead of Stock recovery.

If you just want to boot it once. check backup guide by using this command instead

fastboot boot <file name>

ROOT

Download the ZIP file SuperSU v2.76 and save it in the micro SD card.

Restart the phone in recovery mode:

Turn off the phone, then turn it on while pressing the volume up button. a screen appears with various options and choose "recovery".

You can even boot by adb commands using

adb reboot recovery
[*]

When opening the recovery, select Install and locate the file you downloaded just now.

Confirm execution flashing, restart the phone and voila!

BACKUP GUIDE

I HIGHLY RECOMMEND TO BACKUP YOUR DEVICE BEFORE YOU NEED TO EVEN ROOT YOUR DEVICE OR FLASH TWRP . IF YOU FAIL TO DO THIS, YOU WILL HAVE TROUBLE UPDATING YOUR PHONE VIA OTA ESPECIALLY IF YOU ROOT YOUR DEVICE

THIS IS MUST AS YOU CAN ALWAYS EASILY REVERT BACK TO YOUR ORIGINAL STOCK STATE IN CASE YOU NEED IT.

Download TWRP from HERE or Download recovery from this forum. All credits to the developer to make it possible DOWNLOAD IT FROM HERE. TWRP WITH EFS BACKUP AND MORE

YOU DO NOT NEED ROOT

I suggest you use the second TWRP as it supports more partitions than the first one.

Open working adb

TYPE IN

adb devices
adb reboot bootloader
fastboot boot LenovoA6020_TWRP-3.0.2-r3_7M.img

OR

fastboot boot TWRP-k5-3.0.2-r2_shreps.img

You will be booted into recovery.

Select Read only mode

Go to backup

Backup all partitions by selecting all of them

Swipe to confirm.

Make sure you have about 6GB for a full backup

You can skip user data if you do not want user apps backup

Nothing will be changed unless you enable system modification. So on first boot, simply do not enable system modification and go to backup and then backup all partitions. Keep these safe in case you need them.

Keep it in a safe place

doesnot work for me. Anyone can check by updating their busybox ? I couldnot on supersu 2.76 without updating busybox

OTA FAIL

ERROR 101 System doesnot allow change of carriers

download lenovo smart assistant

Install it and try to update it using this. If it does not update, find update package in lenovo tool folder

C:\Program Files (x86)\LenovoSmartAssistant\LenovoSmartAssistant\plugins\75fc9be6-29e6-495f-8c0a-93f9e1971133

Extract it and find system.zip and your country ota (both) in the sequence

Country.ota.zip (image taken from QPST)

Country2Default.ota.zip (image taken from QPST)

System.zip (image taken from FullOTA)

Does not flash with no error but system not updates and shows update again

Must flash system using QFIL

I used Indian firmware as I couldnot find for my region and thus I always had the error. Can not switch carriers.

I went to recovery and then 0>OTA> Flashed India OTA

Checked for system updates and this time it worked fully.

You can check which is supported by ####6020# in dialer

THIS IS GOLD. DO NOT MISS IT AT ALL

[Lenovo Vibe K5 Plus Guides, News, & Discussion] Hnk1:
It should work flawlessly. I do not see why! Did you do as instructed ?

Well, I have not tested this with a XIOAMI device with QFIL. In theory it should work, but I have always preferred MIFLASH as it is designed specifically for Xiaomi devices. Most of snapdragon devices has an emergency download mode.

Do you want me to add it to the guide ? Which region is your device from ?

What do you mean ? QFIL should work on all lenovo devices (snapdragon) provided you have proper stock images which are specific to your device. Google is your friend ? TWRP and development is not currently my aim for any device yet. As i did all my experiments using a K5 plus so I could write in length about it specifically.
[Lenovo Vibe K5 Plus Guides, News, & Discussion] rafaellancas:
Thank you for your time man! Twrp does not work with my phone (I mean, I can install it, and root/flash some stuff, but it definatelly does not work for flashing any of the images uploaded here, including the backups or the pac/cyanogenmod roms, they all give the same compatibility erros as the roms were not made for this phone). I followed the instructions, wiped system/data/dalvik, tried to flash, compatibility erros. There is no way of backup too, since it crashes at the ending. I'm starting to think that my phone is not the a6020l36 (even though it says that on a label under my battery, on my phone's setup and also on the box), but some variant made for my country only. And I know that are brazillians that claim to make it work on their phones, but since there's no way to guarantee that we really have the same phone, I don't now what to do. The QFIL stock rom (that I got from another place too, the ones uploaded here don't work either (another reason to think that my a6020l36 is different from the ones people claim to work here)). Thank you again for your time.
[Lenovo Vibe K5 Plus Guides, News, & Discussion] Hnk1:
Sorry mate that this did not work out for you. I am sure your device be in warranty. Use that. Always remember the rule " I put it on charge and in the morning i found it like that" or "I tried to update over the air ( OTA) and then it wouldnot turn on " Update me what happens. If it is not in warranty, it could be that your bootloader is locked by your carrier.
[Lenovo Vibe K5 Plus Guides, News, & Discussion] rafaellancas:
Thank you again man, you're awesome! I made it back to stock through QFIL, it's working fine. I just wanted to test and give logs to people on cyanogenmod or pac rom to help it get good on my phone, but since I can't do it, I'll just use the crap stock rom.

I bricked a previous Huawei Nexus 6P phone, and I could only get it to boot into EDL with the computer detecting a COM port attached.

to my knowledge, neither Huawei nor Qualcomm provide the necessary files for an owner to restore a Nexus 6P if the bootloader isn't working.

do you know of any way to extract the necessary files from a working phone, in case it gets bricked in the future?

The QCN backup section is of interest to me, but where would I begin to look for the correct firehose/MBN file and xml file for my device? any suggestions?
[Lenovo Vibe K5 Plus Guides, News, & Discussion] Hnk1:
I am out of touch with Nexus lately, but if i remember correctly, Nexus is so easy to flash regardless of the situation. Were you able to boot into bootloader or recovery or download mode or adb?

Usually the files are provided on google nexus website and just find how to manually flash them. You need to extract them in a certain way (I have guide on Nexus 7 2013 I think) and you can flash it easily! (Google flash Nexus manually)

Plus, i think you can make backup of your device including system using DIAG mode and root. once you are in DIAG, then you can easily make using QPST.

This is a rough idea mate as I have never tried to do that.

Have you tried EFS Backup Professional tool on xda ? It can backup partitions as well.

Another way to restore is by using adb commands. That should help too but you will have to manually give commands.

Hi there mate

Which device are you using and which firmware are you trying to use ?

Are you sure the firmware matches your device ?

Kindly give me more details please!
[Lenovo Vibe K5 Plus Guides, News, & Discussion] Turbonanox:
First of all thank you for your answer. Well I have a lenovo vibe k5 A6020I37. I'm using the original firmware downloaded from the lenovo smart assistance tool. The story started when I tried to recover the efs folder flashing this rom with qualcomm tools (Qfil), but when I tried to run properly to flash I entered into this constant state of brick. Reading more I find that is a emergency download mode, plugged in pressing the keys or not it always get dame download mode (just red led on and nothing boots). Qfil shows a Sahara fail always even trying to chose different files from the firmware. And I guess that's it. Deleted accidentally efs folder, rooted phone using temporary custom recovery (twrp),not sure but I never unlock the bootloader, just enabling the option from programmer options. I know this case is very heavy or bothering to check but I'm very desperate to get a solution and I'm hoping anyone can help me. And if you need me to do something to facilitate the recovery process I'm totally agree and able to make it. Thank you again for your answer and for your attention, I really hope you can help me. Have a good night. Saludos!

[Lenovo Vibe K5 Plus Guides, News, & Discussion] ADelacroix:
Its a windows driver problem. This happens because windows can't know what drivers to use in every kind of situation, and when you install minimal adb drivers your windows stays with more than one driver.

You will need to change the lenovo active driver in windows device manager. So just put the celphone in download mode (shutdown the phone, press the volume up button and the power button, select download mode), with the phone connected to your PC go to the devices manager in windows, select the device (k5 Qualcomm or something like that) and change the driver to another one.

Changing drivers solves the Sahara problem in qfil, the lenovo smart assistant flash fail and the waiting for device in minimal adb software.

Additionally, perhaps just trying the procedure in a different USB port solves the situation, because in every USB port can be active different drivers.

And by last, remember that your phone have different modes, download mode, fastboot mode and adb mode, every mode have your own driver. Its a mess, good luck!
[Lenovo Vibe K5 Plus Guides, News, & Discussion] Techbox24:
I should change the drivers to which one
[Lenovo Vibe K5 Plus Guides, News, & Discussion] ADelacroix:
It is a good question, unfortunately I don't remember the names(neither if they have different names), I think you will need to change and test, this is why I have said "its a mess, Good Luck!"

And I don't know for sure, but I expect that just changing the driver for download mode will solve, if not, try to change the fastboot drivers too!

For me, the device manager shows a lot of drivers in every mode (I have installed too many drivers on my machine).

Tip: if you are impatient and have another machine available that never gets contact with these bunch of lenovo drivers, you can try installing your firmware by this clean machine!
