step by step to change any device IMEI

When people hear imei tweaking, they wonder what exactly it means... but it not something  one need to wonder about. here are the step to follow:

Dial *#06#, write down your Default IMEI, or
Simply Back it up on ur SDcard >> See this Post on
How to Backup IMEI on Android.
2. Run the MobileUncle tools App
3. Go to >> Engineer Mode >> Engineer Mode (MTK)
4. Scroll down to CDS Information
5. CLICK
>> Radio Information
You'll see something like:
Phone1 -
Phone2 -
In that select Phone2, because in most of these
Chinese cloned phone, the 1st Sim which is a 3G will
work perfectly. Problem only happens when we insert
the second sim. Such cases are experienced if after
you check, you can see the IMEI of 1st sim starting
with 35xxxxx and the 2nd will start with 88xxxxxxxx.
That is why the second sim is not able to register to
the network, because its not in international formatted
IMEI. So usually we need to change the IMEI of
Phone 2.
When you select any of Phone1 or Phone2 - you'll
find AT+ __________
Inside there input your new IMEI number,
click >> SEND AT COMMAND
That's all!
Some devices are different and may want to prove
stubborn, so here's an extra tip just in case the steps
above didn't work for you.
TO CHANGE IMEI FOR SIM1 OR
DEVICES WITH ONE-SIM ONLY:
Type the following command then Press Enter or click
SEND AT COMMAND
echo ‘AT+EGMR=1,7, “IMEI_NUMBER” ‘ >/dev/
pttycmd1
TO CHANGE IMEI FOR SIM2 (DUAL
SIM):
If your phone is dual-sim, type this
command: echo ‘AT+EGMR=1,10,
“IMEI_NUMBER” ‘ >/dev/pttycmd1
Press ENTER or SEND AT COMMAND
if you get errors saying "Sending Failed" or "module
not supported for device errors"
When you get the AT+EGMR
Make sure you leave a Space between ‘AT+EGMR=
(and) the IMEI Number
For example > ‘AT+EGMR=[space]"2345XXXXX"
Now Click SEND AT command, You'll get response "AT
command is mSent"
Now restart your Infinix Hot. That's all.
Yes we are done… now you can restart the phone and
check the IMEI. See if it worked by dialing *#06#
