Wait a minute!!!

Hello all,

Down below you will see the original thread of this topic and the help from many people who are very kind to me. Anyway, I just wanted to update that I found a way to get my original IMEI back now. But... still can't make any call... :(

So, for everyone who has the problem of "Error mount efs" just wait a minute before try to do anything with your phone... I have posted the new thread about the problem of my phone but seems like people like to come and post in this thread more...

First Issue!!!!! for people who have efs corrupt...

Your problem started at the same point as mine... If you need me to help please, kindly explain all the details to me to my private message box... and please leave your e-mail so, I can mail you back in case I don't have time to come and answer you here... Normally when your efs corrupt, your phone can't boot up normally. You will stuck on Bootloop... which is softbrick... so, don't panic... be calm... everything's gonna be fine... I was panic at that time and ended up that... there must be some mistake been made to my phone when I sent it to repair... So I suggest you who have this efs corrupt problem to take a deep breath and search through internet a lot... learn more about your phone first before you do anything...

Second Issue!!!!! for people who have imei changed...

For the phone that has problem about imei changed only...(no error mount efs) I strongly suggest you to... restore your efs backup first... If you don't have efs backup... Then I suggest you to go back to the last firmware you are on... if that's not help... let's try the stock firmware of your phone... If the single file is not enough let's do it separately with PDA, MODEM and CSC...

I have learned new thing about the Samsung firmware that... they are not prefect... many firmware of Samsung can harm your efs folder and make your imei change... even though your phone never been root, never been on custom firmware, never installed infected apps, doesn't mean you will never ever have this imei problem... Again...people, be clam... everything's gonna be fine... There are tools and methods that can fix your situation... but as I said...you must know your phone first before you do anything...

BEWARE!!!!!

I must tell you the truth that I'm not an expert... I'm just the girl who has the problem with my very first Samsung phone, and I'm trying real hard to find a way out from this situation... with help from good friends of mine all around the world... They all are so kind and so helpful to me so, my phone can boot up normally again but...not completely fix yet!!! My problem is harder, tougher... and more difficult to fix... there's a tool that may fix my phone's problem now...but I just wanna try to do something else first to see what exactly is the problem of my phone... so I can give you all the details about it later, clear and true. Including the solution of these problem also...

Down below is the beginning of my problem...

Original thread:

Hello everyone,

My name is Angel from Thailand, I have problem with my S4 GT-I9500 two weeks ago about "error mount efs" anyway, after a week of searching for solution I've finally made my phone boot up normally.

But the IMEI is a fake one "004999010640000" I'm trying to find a solution for this problem but so, far...going nowhere... tried many methods from this site and many other sites but still can't fix it... the phone right now can connect to wi-fi, I can use social app and connect internet as usual but can't call out or accept call...

The phone is on latest stock firmware I9500XXUBMEA root already... I try to look in the files from efs folder, open nv_data.bin in Hex Editor but can't see IMEI anywhere... I'm not sure if it's the right place to look for or not but after search through internet for week I found some picture of nv_data.bin in Hex Editor, it's from the good phone with good IMEI, I can see that in text field it has IMEI there...but mine is not!!!

Then I found article about EEPROM, that it contains the real IMEI permanently. So, I'm trying to find a way to read or pull out that file from EEPROM but...there's none can answer this...

So, I'm back to search for IMEI repair service, but no one can guarantee that it supports model GT-I9500...

So, I'd like to ask...if anyone has idea of how to fix this IMEI problem?? I'm so exhausted now... I just bought this phone for only one month...now it can't make any call... I really need help for this issue... so, please...if anyone has idea for a way out, please point me direction...(not SAMSUNG Service...my phone is not in service...) Thank you so much for your time...:)
