Hi,
Edit your post and remove your IMEI and S/N. Just in case to protect your device from illegal tampering or any illegal things.
Where country did you live in? Could you check your phone box for CSC code? It looks like this: GT-I9500ZWAXSE or anything similar.
Sent from my ASUS_Z00AD
Your original CSC according to IMEI is XST
Model number is GT-I9505ZKAXST

Enter the IMEI and it should return the original CSC, which will be the last three letters of the model number, e.g. O2U in I9505ZKAO2U.

Install this APP and it will give you all the info you need about your device.
@Joku1981: He was trying to discover the original CSC/country code the phone was sold under, which is why he needed to parse the IMEI. Phone Info wouldn't help in this instance because it reports the CSC/country code of the currently installed ROM.

In this case, he lost his IMEI because he has flashed other modem and needs the original CSC code. So, Phone Info will useless.

Follow the link of Strephon Alkhalikoi.
Download mode shows your original Country code, no matter what CSC you flash
Turn off your phone, then press Volume Down + Bixby Button + Power button once for 4 seconds.
A blue screen will appear saying that do not flash non original firmware, press Volume Up.
A screen will come up saying at the top "ODIN MODE".
In this screen, you have some information about your device, but the one that we are intrested is a red line "CARRIER_ID: XXX"
That ID is your CSC code, no matter what firmware you install it on. Mine is PAN - the original - even though i currently have DBT installed.
and just press Volume Down + Power key for 7 seconds to restart to normal mode.

I got this I9500 international phone and my LCD display has a pink line across it now.
Samsung USA said they are not covering the warranty since it is an international phone. I need to know where the phone is made so maybe I can contact the Samsung international to fix my phone.
Does anyone has any idea what to do with this case??
Thank yoU!!!!

IMEI can be found under your battery. Do not think of altering your IMEI as this is illegal.
Please also use the Q&A section for questions next time, as this section is for general discussion.

If you are still on stock firmware check your firmware version.
Sent from my LT26ii using xda premium
There are 4 ways to check imei.
1. Checking imei within Android (Dial *#06#)
2. Checking imei within Android and select apps, settings, more, device info, status
3. Removing battery and check the sticker
4. Check the galaxy s4's box
You can check CSC Code of your phone. If you haven't modified it then.
Check the CSC with *#272*IMEI#
And check country list from here.

Hi,
Does anyone know where I can find the stock firmware for the SM-G530T1? I've looked and have not been able to find it.
Edit: It would be possible to get the firmware using the IMEI number in SmartSwitch. Unfortunately I and another are unable to access our IMEI number from the settings in the phone since our phones are bricked. We'll need someone else with the phone to take care of that. It would be tremendously appreciated!

I'll see if that works. Thank you for the info.
Edit: Okay, I've got some good news and some bad news.
The good news is that I found my IMEI number using the method described by Eker. Also, the IMEI number is on the sticker behind the battery but it doesn't say it's the IMEI number, so now we know that. It's the number above the long bar code with the slashes in it.
The bad news is that SmartSwitch says the device is unsupported and when picking "Emergency Software Recovery and Initialization" from the "MORE" menu at the top, nothing appears in the first tab and in the second tab, entering the phone model (SM-G530T1) brings up a new box asking for a serial number. I entered the IMEI number (with and without the slashes) but it says the serial number entered is not corrected. Same thing using Samsung Kies 2 & 3.
I don't know what to do

Damn, that sucks. I mean, that's not totally bad. It would just be better to get the firmware and do it ourselves. That way we can post the firmware here and other people who can't or don't want to go in to a service center can do it themselves. Hmmm...

Just chatted with someone from Samsung and they said the firmware will not be available online. I'm not sure if they ever officially provide firmware to begin with though, so that may or may not be news. I guess the only way to get it is if someone else unofficially provides it...

Even with serial number it wont be possible, smart switch just closes with serial number. Looks like samsung doesn't support smart switch recovery for this device.

I seem to have deleted my IMEI after recovering via TWRP and now I am not able to connect to my network operator anymore...
I was in a similar situation a while back. The tool and steps found here helped me rewrite my IMEI on my A2017U. I lost it after a couple of mindless flashing.

It was simple and effective. Like I said, I rewrote my IMEI ( the one ln the back of my device) and didn't have a problem with cellular, data and/ Wifi.

Mi scuzi
Mmm... I succeeded in rewriting my IMEI numbers, had to go back to stock and had a hassle with rerooting the phone, but in the end that part was succesfull.
Sadly the network connection is still non functional. After rewriting the IMEI numbers it started of with full bars but no data connection, after a few minutes
the phone disconnected from the network all together.
Seems that the issue is a bit harder to solve and according to different topics pretty much unsolvable...

Well, I'm on the A2017U, and I followed the exact steps on the page. Make sure you meet the requirements before starting and take your time. It's easy to make a minor error in these things if you're desperately looking for solutions
After an update to B13 without bacukp, my A2017 B07 has lost the IMEI, when 'call' * # 06 #, imei 1 and 2 are 000 ..., when accessed through the phone menu, a different value of the real appears.
I tried
- https://www.gizdev.com/repair-imei-snapdragon-device/#prettyPhoto
- https://www.youtube.com/watch?v=m1zwvTU7ajM
but the two options unsuccessful.
Could someone help me in any way? If I had some EFS backup, could I change the IMEI with ease?
Sorry for my english, I'm using GoogleTranslate.

Combo files don't work on the newer T720s. But, there is a good chance that your tablet is still in warranty in which case you can contact Samsung and they'll send you a free shipping label to send them the tablet so they can remove the lock.

There is a serial number printed on the back of the tablet. (Very hard to read!) Call 1-800-samsung and give them the number and they will tell you. You'll need proof of sale and they'll send you a shipping label.

No, you can't at this time. Everytime someone finds a way, Samsung fixes it. I don't doubt someone will find a way around their latest fix, but for the moment, only they can remove the lock. Of course, the whole purpose is to prevent theft, so if neither you nor your friend can prove it is a legit purchase, you are out of luck.
