Hello,

Well from the link you got from kokogambo you will see instruction on top of the page it's the message ofvtge web to tell you how to find your 3 letters of sales code. But the easiest way is connect your phone to PC and run Kies... it will show your current firmware and the last 3 letters in () is the region of firmware you need to download but I've ever read the thread that you can change the CSC of your phone later...

Hope it helps... ;)

Hi,

I'm having the same problem with a samsung s4 GT i9500 that i bought off someone yesterday (claims it's locked to O2 from the UK). I didnt test it cos it appeared new but after after switching it on, it shows invalid imei number. Although the imei is on the box of the phone is there but it shows invalid imei in the settings and immediately the fones get turned on.

I later found out there is an email attached to the phone aswell so it was used. PLS HELP HELP! Not a computer whiz but need help seriously right now. Any help or advice will be appreciated. Thanks

Flashing mg9 modem is just only a workaround and uou cant downgrade...

Btw, Ive been here before.. from crash rom mg9 after downgrading to stock mg1 my imei shows fake imei.. i have different back ups of my efs but evwn restoring, nothing works.

But now Im on mg1 and I even downgrade to mdk...

What I did is on philz recovery I clean the system first then flash a stock rom (the rom when i get my s4 out of the box), that really works for me..

Hello there,

Sorry for late reply... well it seems like there many good advise here for you...from post 57 & 58 it sounds a good way to try... now...for me I also try that MG9 also but doesn't bring my phone back to call as normal phone anyway...and after flash back to other modem the imei has gone wrong again...but I have efs backup so...nothing much to worried and when my phone is already broken(can't make call) so I don't have to worried about the signal that maybe lost if I flash another firmware or another modem... anyway... for the imei problem...well all I can say right now is try to go back to your stock firmware first...if that doesn't help...well let me know later in pm.

Hello Austine,

Sorry for late reply... Well, My phone has the original imei back but can't make any call... so I see no use to tell you now how to get it back when it may damage your phone more than fix it...

At this point all I can say is...I'm still try to fix it... if I can find the right solution then I will update the first post... for now I have to ask to do me favour by searching through internet try to find the way out... and share that info with me first before you do anything to your phone...

If your phone never had efs corrupt problem then I can say it's easier to fix it... but mine is the worst problem...as far as I know...about software issue... I have some good and kind people who try real hard to help me fix the phone and we communicate to each other all the time... If I have the right solution I will let you know...

Be patient my friend...

you can put it in pda or phone or csc or bootloader, same result

sometimes efs is not detected after flashing, it doesnt mean that it is corrupted. usually flashing an older modem twice will fix the issue

Was wondering if you could help me with a simular problem on my US Verizon S4. I am NOT able to make or recieve calls, a message pops up saying "Mobile network not available", However i am able to send and recieve to text, but also a different message does pop up saying "No signal found for mobile networks". I did check my IMEI and it looks the same as on the box it came with. Data works fine as well with no pop up messages exept one at startup lock screen "unable to download" but not sure what this is for, maybe the weather app but not sure. How this all started was i attemped to unlock the sim via hidden menus and seem to do fine but didnt get a confirm after completed that it was successfull as stated in the thread but i may have missed that due to not looking at the phone the entire time while it was rebooting. I am rooted with TWRP 2.5.0.2 and did make sure that the EFS was checked while doing a TWRP backup before the unlocking. So am i able to just restore the nanBU to fix this issue or do I need to try another method like the one stated in this thread dealing with the IMEI? any help or point to a fix/undo thread would be greatly appriciated. thank you

Restoring imei

Hi Angel :) I joined xda just to help you out.

Have you tried a full clean and install of you stock rom? Head over to sammobile.com. They have all the firmwares for your phone including the latest 4.3 android firmware. I read somewhere that reinstalling stock rom will help you to restore ur imei. I think something to do with samsung knowing exactly how to retrieve the imei from the eeprom. I read this on somewhere on xda. I was also trying to install a custom rom and the developer had a warning there that said i shud back up my imei.

Alternatively, since all of ur phone functions are working except the calling function, I recommend you approach your service provider and register the imei number with them to enable calling again. Network providers usually block imei numbers that arnt registered. Hopefully when you present your packaging and ur original imei number (written below the battery) they'll enable whatever imei number u have.

Hope your problem is fixed soon :)
[Galaxy S 4 Q&A, Help & Troubleshooting] aznne0:
Similar problem.. hope someone can help me out.

I purchased a phone off CL. I tried to put a SIM card in but it doesn't recognize one. So i realized the IMEI number on the back does not match the IMEI number in android OS. It doesn't say 000000 or one of those fake IMEI 049 numbers. It just has another IMEI number. My question is, is there a way to modify the numbers to match the IMEI number i have on the back of my phone?

I actually didn't know it didn't match until i sent it to samsung to fix. I thought it was just a problem with the SIM tray but they stated that the IMEI numbers don't match. As a result, they just sent my phone back without fixing anything.

Please help me out. It's on stock rom and not rooted

gt i9500 imei fix 004999010640000 /01

Hi,

I had the problem of fake imei or no service after flashing 4.2, root with CWM and flash cm11. In the process I downgraded 4.2 official samsung rom xuamdk rom from 4.3 official samsung rom on my gs4.

search for days.. but could not find anything to help imei fix and I had no EFS backup, but this resolve my problem finally.

downloaded a new official rom 4.2 from sammobile adapted from my country code.

enable debug mod and then select usb debuging

Hold up key + homekey +power key to enter recovery mod..from there factory reset and wipe cache memory

power of device, hold down key + home + power to enter download mod

flash the new official rom 4.2 into my phone via odin..at that point firmware is still custom and no service imei 004999010640000 /01. update error: could not connect to server.

connected phone via usb to samsung kies and update firmware to 4.3 ..dont forget to give administrator access when prompt to do so

After the firmware update firmware became xuemj8 with official status and imei was repaired

that serves me right.. should get enough information befor flashing stuff on my phone and should back up efs

hope it will help those who have the same problem and has not recover imei or i would be just one stupid guy who "get lucky";)

So I have read 10 pages of BS and the traumatic stories of Angel from Thailand and Co about stolen or fake IMEIs. There is still no clear procedure on how to fix or repair an invalid IMEI. It drives me crazy how people quote or post links to other threads instead of just either type a solution or copy paste the little information that they have. What is the use to confuse eveybody by sending them to another thread so then you have to monitor at least 2 threads!?

The problem is simple. Clean phone, stock ROM. IMEI no recognized anymore. Obviously no network connection with IMEI. How to fix it? I have my IMEI on my phone bill and on my phone box.
[Galaxy S 4 Q&A, Help & Troubleshooting] Skipjacks:
If you have your efs partition backed up in recovery, just restore it.

Problem solved.

If you don't then unfortunately the method to fix it cannot be discussed in XDA because its the same method that is used to replace it with a fake imei (except the 'new' imei for you is the correct imei)

We simply just do not discuss those methods on XDA because we don't want to be a part of helping someone use that info for the wrong reasons.

Google will help you find what you need elsewhere. But unfortunately we can't give it to you here.
