[Lenovo Vibe K4 Note Guides, News, & Discussion] Sahil_Sonar:
Overview ​

Now, I have seen many people facing problems like lost IMEI or NVRAM warning in their wifi list! Well, these are normal errors when you often flash a custom and wiped system or update using SP Flash Tools. So fix isn't that hard! But still, many people suffer from this! Now, this guide is applicable for every device(MTK) but BPLGU modem file will vary from device to device. I have specially made this guide for Lenovo Vibe K4 Note users!:laugh:

So lets fix it up !:D

Required stuffs !

Windows PC (7/8/8.1/10)

Usb Cable

Few tools

Drivers

Your device, ofc !

Download Section !​

1. Scatter files !

2. MauiMETA

3. Temoprary IMEI fix.zip​

Now before we start doing anything make sure you download everything from the download section. Also, make sure your device is having TWRP installed.

Process !​

Now most of you must have thought hey Max where is NVRAM fix? There was nothing about NVRAM in title Well chill down I will target NVRAM NOW !! :cool: So let us begin! Now as you have downloaded entire scatter files so NVRAM needs entire scatter files. "Woosh! Thank god it was useful somehow" most of you must have thought :rolleyes: Hehehe Well one more thing if you are using permanent NVRAM fix then use it before you flash IMEI or else you lose it again if you fix NVRAM after IMEI. However, a temporary fix can be flashed later on.

* Now navigate to the firmware folder

* Look for scatter file open it in notepad or notepad ++

* There look for this line, "partition_name: NVRAM"

* There you will also notice, "s_download: false"

* Just change it to, "s_download: true"

* Save and exit!

* Open Sp flash tools and load scatter file(Remember a thing, you will have to use an older version of SP Flash Tools)

* You will see checkbox of NVRAM just choose it and keep rest options unchecked!

* Flash into your device and all set!

NVRAM IS FIXED PERMANENTLY :good:

But now for those who are lazy doing this, there is a temporary zip file which you can flash and NVRAM problem will be fixed for a limited time to do so just go to download section and download temporary fix zip file and flash it into TWRP (Yes, that's why we needed TWRP):angel:

Now before we start doing anything make sure you download everything from the download section. Also, make sure your device is having TWRP installed. (YES AGAIN MAKE SURE YOU HAVE EVERYTHING)

• After that, run Maui META 3G

• Use USB COM

• From Options menu, select “Connect smartphone in meta mode”.

• Press Reconnect and connect the phone in the switched off state.

• Wait for a minute. Your Device automatically boots into meta mode. The blinking led will become yellow and you can see "connected with target"

• Now from the drop-down menu select “IMEI download”. Click ok till you see IMEI download box.

• Click Change NVRAM Database FIle and browse to “MT6753 DB” folder and select the following file.

File\MT6753\

BPLGUInfoCustomAppSrcP_MT6753_S00_K5_ROW_LWG_V56_ 1_lwg_n (BPLGU modem file for mt6753, do a double check as the name might change with firmware versions).

[Well I have not extracted this file yet from stock ROM scatter files. However, I have given you the download link of entire stock ROM look the file there itself !]

• Click ok on any warning.

• Leave IMEI Increasemnt 0.

• Write first 14 digits of your IMEI in IMEI box and last 15th digits will go in checksum(should be entered automatically). Eg:- if IMEI is 123456789123456, write 12345678912345 in IMEI and 6 in the checksum. Do same for Sim_2

[Now most of you must be wondering where is my IMEI. I don't remember it and also it's not there in the list. Don't worry pull your back cover and you will see IMEI sticker there just type the same IMEI]

• Press Download To Flash. You will see Download IMEI flash successfully. Now close the box (or alt+f4 or close from task manager if stuck).

• Restart the phone

• Open Dialer and type *#06# and you will get your valid IMEI number.

* Well if you saw the same IMEI then you are done !!! :good:
