How to fix “Invalid IMEI ” after Factory reset?

Solution : 1

Install the Mobile MTK Engineering Mode app. This will only work on devices with a Mediatek chipset.

This Application allow you to run Advanced Setup from Engineering Mode Menu of MTK phones, also called SERVICE MODE

Other apps which can show the MTK Engineering Mode Menu will probably work too.

If you can't find or don't know your phone's IMEI, then install the Bb IMEI Generator app to generate one for you. If your phone has dual SIM support, you'll need two IMEIs. Note the generated IMEIs by Bb IMEI Generator.

In the Mobile MTK Engineering Mode app go to > MTK Settings > Connectivity > CDS Information > Radio Information > Phone 1.
At the AT+ line:

Enter AT +EGMR=1,7,"ENTER-IMEI-HERE", then tap on 'Send AT Command'. If you have a dual SIM phone, enter AT +EGMR=1,10,"ENTER-IMEI-HERE" then tap on 'Send AT Command' again. Note: The quotes are included. There should be a space after AT.

You should get a notification that the AT Command(s) were successfully sent. Restart your device. You now shouldn't get the 'Invalid IMEI' notification.

Solution : 2


Need to root the phone - I use z4root
Install Root.Explorer (in the archive)
Using Root Explorer you must replace (maybe you will need to press "Mount R/W" on top right corner of the program screen) .modem.img from the archive to this location of the phone /etc/firmware/.modem.img (do not delete the old file !!! replace it!)
Set permissions for the .modem.img file to rw-r--r--
Restart the phone and maybe will be OK, but if it is not go to next step
IMEI information is stored in /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001. Maybe changing of your original IMEI is not good idea because it is against the law but if you don't have copy of that file BEFORE the factory reset you can use temporary IMEI file located in the arhive.

Turn An Android Phone Into An Infotainment System

of 07

No infotainment system? Grab an old Android phone, and you're good to go.

the items you'll need for this project

If you have an old Android phone laying around, it's surprisingly easy to turn the device into a serviceable infotainment system. The end result won't exactly match the kind of functionality you get out of a fancy new OEM infotainment system, but you can make a pretty good stab at it without spending a lot of money.
The main features that you'll be able to add with this project include access to vital data from your vehicle's onboard computer and the ability to play music, video, and other content via your vehicle's sound system, and turn-by-turn navigation, just like a real infotainment system.
In order to complete this project, you will need:
  1. An old Android phone you aren't using anymore.
  2. Bluetooth or WiFi ELM 327 scan tool device.
  3. An FM modulator or transmitter, or a head unit that has an aux input.
  4. Some type of mount to hold your phone in place
  5. An OBD-II interface app
  6. Navigation and entertainment apps
Your results will vary depending on the type of Android phone you use, but this project was completed with an old G1. The G1, also known as the HTC Dream, is literally the oldest Android phone in existence, so just about any handset you have laying around should work. The phone in this tutorial is running custom firmware, however, so a G1 that has an outdated version of Android may not be able to run some of the latest diagnostic and entertainment software.

Locate the OBD-II connector in your vehicle.

an OBD-II connector

Unlike old OBD-I connectors, most OBD-II connectors are very easy to locate. The specifications state that the connector has to be within two feet of the steering wheel, so most of them are located in that vicinity.
The first place to look is under the dash to the left or right of the steering column. You may find the connector right up front, or it may be mounted back near the firewall.
If you have trouble locating your OBD-II connector right out in the open, you'll want to be on the lookout for removable panels. Some connectors are hidden behind removable panels under the dash or even in the center console. Your user’s manual will often show you where to look, or you can look for a picture on the Internet.
Some OBD-II connectors look a little different than others, but they all use the same pin-out. If you find a connector that is about the right size and shape, even if it looks a little different from the connector pictured here, it's probably what you're looking for.
If you gently insert your OBD-II wireless scan tool device, and it goes in, then you're on the right track. If it doesn't go in easily, however, you probably haven't actually located the OBD-II connector. The fit should be smooth and easy, and you should never have to force it. In some cases, the connector will come with a protective cover installed that you will have to remove first.

Plug in the OBD-II interface.

Install the Android interface software.

G1 running Torque

Once you're all plugged in with your wireless OBD-II scan tool device, the first step toward really turning your Android phone into an infotainment system is finding the right apps, and the first one you'll need is an interface app.
There are a number of OBD-II interface apps available, so you should be able to find one that will work with your specific hardware and version of Android. Some are free, while others are quite expensive, and some paid apps also have free trial versions so you can get your feet wet before you spend anything. Torque is a popular option that offers a free “lite” version that’s useful for just testing your system.
You may also want to try out a free version first to make sure that the app will run on your phone and connect to your ELM 327 device. Even if the Google Play store says that an app will run on your phone, you may find that it refuses to pair with your scan tool.

Pair your Android and ELM 327 scanner.

android wireless settings

If you’re using a Bluetooth interface device, you’ll have to pair it with your phone. Pairing sometimes fails, which typically indicates an issue with the interface device. In that case, you may have to obtain a new unit.
Once your Android is paired to your scanner, you'll be able to access all sorts of important information from your vehicle's onboard computer. It isn't exactly the same as the types of monitors often included in infotainment systems, but it's a close approximation that you can get working on virtually any vehicle built after 1996.
of 07

Set up your FM transmitter or auxiliary cable.

An FM transmitter plugged into an Android phone

Once you have the information part down, it's time to move on to the entertainment.
If your head unit has an auxiliary input, then you can use your Android phone to play music through that interface. However, it’s also possible to do the same thing with an inexpensive FM transmitter or an FM modulator. You can also use a USB connection if your head unit has one.
The sound quality can vary from mediocre to great, depending on the connection method you use, but either way, you’ll have access to your music library or Internet radio apps.
In this case, we have hooked up the G1 to an FM transmitter and tuned the radio to an unused part of the broadcast spectrum. This allows the phone to transmit music, or anything else, over the vehicle's speakers.
Many Bluetooth car kits achieve this same basic type of functionality, and you may be able to use your Android phone for hands-free calling if it still has an active voice plan.

Install other infotainment apps.

G1 Infotainment Device

After you're up and running with your OBD-II interface app and have your old Android phone connected to your car audio system via an aux input, FM transmitter, or other means, you're good to go. You'll already have the basics of a do it yourself Android infotainment system going on, but there's no reason to stop there.
If you have an active data connection on your phone, or a mobile hostpot, you can turn it into a true infotainment system that can monitor your vehicle through the OBD-II interface, play music, provide GPS navigation with turn by turn directions, and virtually endless other functionality through other apps.
