How to Backup NVRAM Image for Lenovo Devices
Get the scatter file
First thing to do is we must get the scatter file of your device, scatter file is file that arrange a partition on your device.
MtkDroidTool will only work if you already install ADB driver, so please see Tutorial : Manual installing Android ADB USB Driver
Enable USB Debugging on your device also, System Setting ? Developer Options ? check USB Debugging option.
Open MtkDroidTool, connect your device to your computer, wait until it appear on MtkDroidTool then press "Block Map" button (1)
On the next window, click "Creating scatter file"button (2) and save it as MT6577_Android_scatter_emmc.txt *MT6577 is your processor model, so you can change it with your processor model
Done, above guide is how to obtain your device scatter file. Now continued to the next step.
Find the address and length of nvram
Now we should read the scatter file and find NVRAM block partition.
Open the scatter file with any text editor, it recommended to use Notepad++ because you can see the format and that make easy to find the block.
Find the __NODL_NVRAM
The string after __NODL_NVRAM maybe different each and another, on mine is 0xA08000
Now look at the next block __NODL_SECCFG and the string after it 0xF08000, *On other devices this maybe different, depending on which block is come out first
So now we already have 2 numbers, 0xA08000 and0xF08000. To find the NVRAM length use programmer calculator and calculate that 2 numbers : 0xF08000 - 0xA08000 = 0x500000
So on this step we got 0x500000
Merge the nvram.img
Create folder named target_binand put the scatter file on the step 1 inside it along with flash tool folder.
Open flash tool folder and run flash_tool.exe
On flash tool, click "Scatter Loading" button (3), browse to target_bin and select the scatter file MT6577_Android_scatter_emmc.txt
Then click "Read Back" tab (4)
On read back window, click "Add" button (5), the table will show N/A row, double click on the line (6) and name the file. ie ROM_NVRAM and the click "Save" button (7)
On the "Read block start address" window, insert address and length that we have received before on the previous step (8).
Start Address: 0xA08000
Length : 0x500000
now you can click "OK" button (9)
Click "Read Back" button (10) , now turn off your device and remove the battery but if your device use non removable battery then you must make sure device is already completely turn off, connect your device. Flash tool will immediate starting the process to read your NVRAM block and save to computer. It will show GREEN CIRCLE on the middle of flash tool once it finish

If device bootloops after flash process, do a factory reset from recovery.
If screen of device divides/displays funny colours when boot up, use another ROM or Firmware
Stock firmwares for LG devices come in KDZ (and sometimes TOT)format. You can flash these firmwares using the LG Flashtool on a Windows PC to either restore a device stock firmware or downgrade from an updated release.
Below is a guide on how to flash KDZ firmwares on LG devices, follow the instructions carefully
Extract/Unzip the LG Flash Tool 2014 .zip file on your PC. You’ll get a bunch of files required to run the program.
Double-click/Run LGFlashTool2014.exe file to Open LG Flash Tool. ? If it doesn’t open, install Visual C++ Runtime Library from here and then try again.
Boot your LG device into Download Mode:
Power off your LG device.
Press and hold Volume Up button.
Connect your device to PC with a USB cable while holding the Volume Up button.
You’ll boot into download mode with “Firmware Update” written on top of the screen.
Now load the .kdz firmware file into LG Flash Tool window on your PC. Click the browse button at the end of the “Select KDZ file”line. Leave every other option as is on the LG Flash Tool window.
Once you’ve selected .kdz firmware file, click “CSE Flash” button to proceed on flashing the .KDZ firmware to your LG device. ? FYI, the “Normal Flash” button doesn’t wipe data and the “CSE Flash” button wipes data. If you’re upgrading from a stock firmware, then “Normal Flash” might do.
You’ll get a “Read Phone Information” window, it will be blank for the most part. Just hit the START button and proceed.
You’ll be asked for administrator permissions for some LG program on your PC, accept it.
Now you’ll see “Select Country & Language” window. Select“Different” from the country list and then “English” from the language list. And remember to NOT tick the Smartphone upgrade checkbox, it’s for Windows Mobile phones not your LG device running on Android.
To finally begin firmware flashing process, hit the “OK” button.
You’ll see a progress bar now. Just wait until it’s 100%, after which you might get an error “Connection to server failed”. This is okay. DON’T disconnect your phone at this point.
Watch your phone closely, you’ll see some activity going on the screen with “COM” written in green text. Once that happens click OK to the “Connection to server failed” error.
Now watch the firmware update progress bar on your phone. Once it’s complete, your phone will automatically reboot. And then you can disconnect your phone from PC and close the LG Flash Tool utility as well.

Improving GPS on MTK devices, Especially on Lenovo - I got this article on the russian Lenovo forum, maybe you interesting and wanna fix GPS on your device, so read and understand it.
What is "Chinese" GPS and how to fight it ... or why not working GPS on CN (and not only) devicesThe bulk of the owners of mobile devices brought from the capital city of China and not only faced with the problem of "not working» GPS. Why in quotes? Because it actually works, the problem is not on the device (or GPS-receiver), and in running with the device almanac of GPS satellites. In this topic I will try to briefly reveal a theory of GPS-positioning and explain how without deleting and editing any system files, including gps.conf, calibrate and customize your device to work correctly with GPS.
* A small digression for amateurs and professionals straightening and replacement gps.conf - this file in OS Android 4.4X (aka KitKat) is absent.
First, a little theory
- GPS ( Global Positioning System ), in a literal translation - Global Positioning System. The GPS system operates on the basis of orbiting satellites that are in six orbits, whose height is about 20,000 kilometers, and the velocity is 3000 m / sec (i.e., daily for each satellite completes two "spiral" around the Earth). Data from satellites are transmitted on two frequencies - both civilian and military. We omit the military, our device is not available, but a civil (1575.42 MHz) allows for error less than 3 meters ( declared by the error of 10 meters smartphones or GPS navigators caused international or other laws on the use of GPS for civilian purposes ) GPS satellites transmit two types of data - the almanac and ephemeris .
- Almanac - contains the parameters of the orbits of all the satellites. Each satellite transmits almanac for all satellites. Almanac data are not very accurate and are valid for several months.
- Ephemeris - the exact coordinates of each satellite, adjusting the parameters of its orbit and clock (these data are not collected in one day, based on the tracking of its orbit and position in the sky, not only on Earth, but also of other celestial bodies). Taken separately GPS satellite transmits data only own ephemeris. Retransmission of satellite ephemeris occurs every 30 seconds. These data are not valid for more than 30 minutes. If the GPS-receiver was switched off for more than 30 minutes, and then re-enabled, it starts looking for satellites, based on his famous anthology. According to the data recorded in the almanac, GPS satellites to select and initiate the search. Now imagine - not only that our GPS smartphone / tablet does not work more than a few months, so it has taken a couple of hundred thousand kilometers from the last-place calibration. From here and "grow legs" in "does not work" GPS.
To our built-in GPS device wound up he needs Almanac of the satellites in the area and their ephemeris.
Creating almanac and ephemeris receipt
* To create an almanac and ephemeris receiving satellites requires ROOT access * All the procedures recommended in the open, or at least on the street
Turn on GPS (this requires lower "blind" and click the icon GPS )
With the help of the engineering code or MobileUncleTools log in Engineering ( MTK ) mode device ( EngineerMode ? MTK )
Once in the engineering menu phone to navigate to the tab Location and go in YGPS
On the tab "Satellites" should be red dots (that satellites), and below them (bottom) signal scales. If the signal scales absent, and satellites (red dots) is, it is said that the satellite phone sees, but can not connect to it because of incorrectly recorded anthology.
For proper operation of the GPS to create a new almanac, in line with our current location : In paragraph YGPS go to the tab "Information", and then, with an interval of 5-10 seconds, alternately press the button "full","Warm","hot","Cold"(thus causing a complete reset of the old almanac).
Warm, Hot and Cold - there are three modes of starting the GPS receiver :
hot - time, position, almanac and ephemeris are known, takes a few seconds
Warm - time position with some restrictions and almanac known. Ephemeris from at least 3 satellites, known since the last shutdown.
Cold - time coordinates are known with some restrictions. Almanac and ephemeris are unknown.
Full, most likely it through all three modes to search for satellites
After that, go to the tab NMEA Log and click on the start - will burn and create new Almanac
After you run the NMEA Log turn on the tailgate "Satellites"and wait for 5-10 minutes until the phone itself does not find all the satellites and connect to them ( * not necessarily all ). Indication of the connection are "greenish" point satellites (remember before that they were red) and "suddenly" earned scale satellites (will bottom) We are waiting until the scale also changed its red color to green.
When the GPS receiver records the satellite, then it shows "empty" bar signal strength. At this point, yet there is a process of data collection ephemeris. When ephemeris of each satellite is adopted, the corresponding signal strength bar turns green, and the data received from the satellite are suitable for navigation.
After connecting to the maximum number of satellites back to the tab Nmea Log and click "stop". Exit the engineer mode, launches Navitel (Yandeks.Navigator, MapFactor: GPS Navigation, Igo Primo or others. To taste) as well as the status of GPS, Google Maps, GPS and other GPS Test app and enjoy life.
And finally, a few words about 2D Fix and 3D Fix 2D Fix and 3D Fix it two modes of error correction using GPS
DOP - indicator of the quality of GPS reception
GPS has its own system of quality criteria for receiving a signal - DOP (Position Dilution of Precision, deterioration of positioning accuracy). DOP quality depends on the ability of GPS [receiver] corrected signals from satellites. Availability 3D fix is ??not a sufficient criterion of quality. If more than 6 DOP indicates poor signal quality. Less than 4 - enough to record tracks OSM (openstreetmap - street map). Less than 2 - very good quality.
When 2D Fix correction occurs based on latitude and longitude
When 3D Fix correction occurs based on latitude, longitude and altitude
Therefore, a good DOPa can achieve even with 2D fix Finally fly in the ointment from Navitel: I do not know 9 (current) version of the program (maybe fixed a), but in the 3 and 5 versions so accurately, DOP is missing. No, of course it is (without it would not work), but only corrects the error in the horizontal (HDOP) and vertical (VDOP) planes
PS In order to calculate the exact coordinates with GPS navigation enough to connect to only three satellites. Video Guide : Original source : http://lenovo-forums.ru/topic/8945-lenovo-s660-?????????-??????-gps-gps-?-???-?-???-????????/
