Invalid IMEI P780

Hello,
I have a Lenovo P780 for 10 month now and I love the phone. The only issue was that the 2G reception wasn't good it fail a lot.
I google it and found I thought a solution. But when I used the uncletools trying to install a recovery something went wrong and after reset the Phone entered a bootloop.
I went to NeedRom.com to donwload the Rom I had P780_ROW_S116_130828.
I used a new version of SP Flash Tool and I didn't notice that the option that was selected was Format+download.
I didn't make any backup of my previous Rom.
Now I have the phone working but the IMEI information is gone, so I can't do phone calls.
I went throught the forum I found a solution but it needs the phone in meta mode. When I do that and connect the phone to the PC windows is trying to install a driver CDC Serial but always unsuccessfuly.
Can any one help me with a diferente metod to put the IMEI information or the driver for Windows 7 Pro 64 bits or Windows XP Pro SP3?
Also I only have an IMEI code on the phone and in the box. Do I put the same code in SIM1 and SIM2?
Phone: Lenovo P780
Andoid: 4.2.1
Build number: P780_ROW_S124_140403
Thanks and regards to everyone

Hi
Let's first try the the easiest way to restore the IMEI.
You have to be rooted to do this.You can root your device using the latest Vroot version.
Install THIS > give the app root rights and follow the instructions from HERE.
A quick instructions recap :
Open --> Engineer Mode --> Engineer Mode (MTK) -->Connectivity Tab -->CDS Information -->Radio Information
- select Phone 1
- you can see AT+ at the top
- type AT+EGMR=1,7,"xxxxxxxxxxxxxxx"(your 15-digit FIRST IMEI)
- press "SEND AT COMMAND"
- reboot your phone
For the second IMEI
- select Phone 2
- type AT+EGMR=1,10,"xxxxxxxxxxxxxxx"(your 15-digit SECOND IMEI)
- reboot your phone
*#06# to check imei
The IMEI should also be written on the phone under the battery.....If you don't find the second you can use the same for both sim cards(generally dose't create problems).
If this method dosen't work I will show you haw to ''invent'' an IMEI back-up...and restore that.
Let me know how it goes

Hello there tamaddon,
It sound slike we need to troubleshoot no service to your phone here. We have a great article about troubleshooting what might be causing this, named iPhone: Troubleshooting No Service found here http://support.apple.com/kb/ts4429. The symptoms in the article are a bit different to what you are experiencing but the troubleshooting is valid.

Check for a carrier settings update. Tap Settings > General > About while connected to a Wi-Fi network. If an update is available, a prompt should appear soon. If Wi-Fi is not available, connect your device to iTunes.

Invalid IMEI Number

Hello, For some reason, i am getting an Invalid IMEI number when trying to register the phone on the sony website. any suggestions on how this could have happened? i have had the phone for about 3 months now and the way i got my imei number is by typing *#06# in the phone. Thank you for your time.

Hi and welcome to the community! Since you're new please be sure that you have checked out our Discussion guidelines.
It sounds like you have entered something else then digits or wrong number of digits. The IMEI should be 15 digits. Depending on phone and where you check the IMEI you may see more then 15 digits, in that case, only enter the first 15 digits.

Lumia 620 Invalid IMEI

I purchased a Lumia 620 from O2 nearly 2 weeks ago and I've been trying to claim the free shell case via the nokia620freeshell site and it keeps coming back with an error message stating the IMEI code is invalid - apparently I'm not the only one this is happening to.
I've also just tried to use Live Chat here on the support pages and when I type in the code there it also comes back with an invalid IMEI.
Any ideas what's going on?

I had the same issue when trying to claim mine as I purchased it on the 31st of January. Yesterday they made changes to the site and I was able to claim.
If it's still failing for you don't contact O2 as advised above, call this number instead: 0843 320 9406 If you aren't happy with what that person says to you ask to speak to their supervisor instead which is what I dad and got a call back from someone in the UK. The number they called me from was 0191 477 5187.
Good luck!

Invalid IMEI on my blackberry 8707v

Hi,
My service provider vodafone is not allowing me to call or receive a call on to my blackberry 8707v. My mails are working fine.
They say my model has invalid IMEI no. which is ***************.
In INDIA this problem is with other non blackberry phone which are made in china. Hence they are importing new IMEI no in to them. But there is no facility for importing IMEI into blackberry.
Kindly advice what is the best way to get out of this problem.
Thanks in advance,
Homesh Joshi

Hi and Welcome to the Forums!
Sadly, your only path for resolving this remains with your carrier. Hopefully they will be willing to work with you and resolve it. But, there is no guarantee...and they are in complete control of the situation. I advise you work with them further and hope that they will be willing to help you out.
Good luck and let us know!

A808T Invalid IMEI

Hi Folks,
I apologise because this is probably often asked, however I purchased a Lenovo A808T and a few days ago it arrived. When I started the phone, it worked fine but apps I removed would return upon restarting. I looked up on the internet and a couple of suggestions was to run a factory recovery which is what I did.
I followed the guide to the point, it was written in chinese and the phone restarted.
Upon restarting the handset came up with "Invalid IMEI".
I've tried everything I've found to fix the IMEI and I have contacted the seller who hasn't replied to my requests. Whilst searching since, it seems a common problem people experience but no matter what I try it doesn't resolve.
It does now state "Invalid IMEI - O2" since I followed one tutorial and checking it does seem to have a signal (which was always 0 before).
I've tried the terminal method, two different flashing IMEI apps and the unclemobile method via the engineer mode. Can anyone help me?
Perhaps I am doing something wrong.

Lumia 620 invalid IMIE

I purchased Lumia 620 from Flipkart 2 days back. I wanted to enter into FCB contest and sent message to 55555 with IMEI and name. I received return message saying my IMEI is incorrect. What is the problem with my phone? I checked IMEI tracker in web, there also it says, invalid IMEI. Is there a generic problem with 620 IMEI numbers?? What should I do now to get/register my IMEI number?

My 8830 world edition won't register to local carrier BIS

I just bought this 8830 word edition from ebay. Originally it's locked to Verizion but I already unlocked.
In a first time when I insert my BB enabled GSM sim card, it's registered and my BIS service works fine. But After I wipe and reinstall the OS (I use 4.5.175 from verizon because there are no any local carrier have it the installer for 8830) - I still can registered (got RIM registration message and GRPS signal) but the service book is not pushed to the device. I am tring to push the service book from my carrier BIS site but there is no response in the device to receive it.
Currently, I can't see the email settings icon - and in the setup wizard there are no option to add/create personal email - just BES email activation. When I go to my local carrier CS - they remove my BIS account and ask me to do wipe and HRT. I do it but again, I got RIM registration message and GPRS signal but no icons for email setings, ym, gtalk that's usually pushed when the new device connected at the first time. Then my local carrier trying to create a new BIS account for me - but got "Invalid PIN or IMEI/ESN/MEID format" message. I ask them to use PIN and ESN instead of PIN and IMEI - still no luck and gota message as below:
This BlackBerry(R) device is not registered with your wireless service
provider.
Please register this device and verify that the URL of the current web
site matches
the one provided by your wireless service provider.
To register:
1. In the Application list on your device, click Options, or click
Settings Options.
2. Click Advanced Options > Host Routing Table.
3. Click the Menu key and click Register Now.
If the error persists, contact your wireless service provider.
My local carrier then check to their billing system and they said my simcard was not connected to the device. Then they said is strange issue and mention about the "invalid imei format" is not normal (the last digit of imey number on the device is 0 but the correct one is 8).
I need help for clear out this issues. Any suggestion? Was I bought a suspended device? I'm trying to email [email protected] asking the information but they just auto-replying. I have plan to rise a dispute on ebay but I need to clearly the issue first.
Hope got any enlightenment from this forum. Thanks.

Hey jackonberry,
Thanks for the reply.
After checking your PIN number I see that your BlackBerry® data plan is not active. Contact your network service provider to resolve this issue.
Let me know if you have any more questions.
Cheers.

Unable to Activate iPhone 5s for Sprint in store pick up

I was one of the lucky few who preordered the iPhone 5S at BestBuy.com, but when I came in to the store to pick it up, the employees were unable to activate the phone. Sprint had a notice posted on the Best Buy register about an issue with invalid IMEI numbers and that the problem was being fixed ASAP. Hours have passed and I haven't been able to find out anything new. I had to leave my phone at the Best Buy and was told to try back later.
Does anyone know if the issue has been fixed yet?

Hello willreinking! I am sorry to hear that you're having issues getting your phone activated. The first thing to do is to make sure that the SIM card number has been updated on your account, so your device is able to program. You can update it on My Verizon. http://bit.ly/xB4iTc If it's correct, the next step is to remove/reinsert the SIM card to start the activation again. Please let us know if this continues, so we can get it fixed for you.
Thank you,

Why my IMEI number showed invalid?

Actually I purchased last year from At&t.
And this week I was trying to unlock my iphone online and also put my number there and today when I was trying to look up that my iphone is unlocked or not
But now its saying invalid number.
There are ZERO legitimate sites that can tell you anything about your IMEI other than Apple or the carrier the phone is currently used with. If you entered an IMEI into a site that claims to be able to tell you about your phone you should be prepared to deal with identity theft.
