GT-I9300 (S3 clone) MTK6575 SMDK4x12 - Phone Dialer error

Problem: Unable to make phone calls, send messages etc.
The Phone dialer, Contact & Messaging apps gives a error msg
"The system is not authorized will automatically shut down"
Once I click YES, the apps closes. (ScreenShort "dialer error"attached)
Same thing happens when I open Contact apps. (ScreenShort "contact error" attached) once I click YES, apps goes but keypad remains at its place.
I installed "Go Contacts EX" from play store, this allowed me to open contacts, and I'm able to make a call to any of them. Call connects, but same error msg displayed, and I cannot do anything else than clicking the YES. (ScreenShort "dialer error 2" attached)

have the similar phone where the SIM location is at bottom rathen than in between the battery & camera.
I cannot install Whatsapp because the phone model is "I9300" which Whatsapp interpret as tablet and refuse to install
So I ask the shop keeper to root it for me. Did not notice if there is any IMEI before ROOT.
After Root, IMEI is lost. Some SIM is still working, some will get no permission or authorization and cannot make / recv calls.
After searching, find a tutorial to write IMEI to insert into. The site is in Chinese and is follows.
www . 5i01 . cn/topicdetail.php?f=586&t=2849328&p=1 (remove the space)
Goto post #2, will see the link for the little program which run in windows
www . dropbox . com/s/149hywwmdwaaqa9/imei_mtk.exe (remove the space)
anti-virus software may report this as trojan. use at your own risk.
basic requirement : phone is rooted (because need to replace the IMEI record)
1. after download this imei_mtk.exe, rename it to imei_mtk.rar
2. extract ONLY the 2 files : imei.exe and readme.txt
3. readme.txt should read as :
i. at dos command mode,
input imei.exe <15digit_IMEI_1> <15digit_IMEI_2>
and it will create a new file "MP0B_001_NEW"
ii. rename it to "MP0B_001"
iii. replace the same file in /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001
4. reboot the phone and you will get the IMEI
note : IMEI is a 15 digits number
The IMEI will be lost after factory reset. Have to do this again.
Suggest to save the "MP0B_001" for future use.

had the same phone, had the same issue, when i uninstalled some apps, simply, flash the official rom or the updated 1

where did you download the official rom? can you give me a link.. thank you.

[UNSOLVED] Unknown IMEI/Baseband

LESSON LEARNT (for everyone): Please make sure to do a complete EFS backup before you do anything or you will end up like me!!!
So yeah I flashed Deodex_LF2_Cwm.zip yesterday, trying to deodex my DDFL2.
And following that I experienced total loss of mobile signal, baseband, IMEI, IMEI SV, and phone (*#1234#).
And I haven't been seeing this kinda thing to come, I did not back up EFS. (Yeah brilliant me)
So I tried a few of these:
[GUIDE] Recover your IMEI in 9 steps
Repair IMEI using EFS Pro
Reflashing from latona.pit then XXKPE; for a few times
Flashing stock ROM for Malaysia region (Froyo and GB)
Flashing various Modem.tar (DDLE1, DXKP7, etc) via Odin3 at different ROM levels (XXKPE, DDLF2, even CM10A4)
Restoring Nandroid backup from other SL user (Thanks Rich'Dawg')
But nothing worked so far yet.
Now that I checked the /efs folder is empty and there is only a folder named lost+found.
Some websites said about fixing IMEI for small fees but in cases of blank IMEI (*#06#), chances are only 30%.
And my last resort would be getting it replaced in Samsung service centre or any repair shop, which I suspect that the motherboard would be more expensive than some simple new Android phones.
Leaving this forum for the moment as to collect more money to get a new phone . . . :crying:
Lastly, thanks for all the input. Greatly appreciated.

Do you able to call anyone. ? if yes then no need to change anything. if no then you should search for imei solution on xda. there is some tutorial for fake imei.

no idea of how much it should be.
but a idea to help you,
1st idea:
go in recovery and fix permission.
2nd idea:
you said you flash Deodex LF2 in CWM, it should not touch efs folder. so, very high change of your nv_data.bin file backup still good.
OK. use any file browser look in the efs folder, see if the below file still exiting, (they are hidden file)
check on the file date. is the date older than the date you flash the zip, if yes, this is the one original from your phone.
the file name start with a dot
.nv_data.bak - ( this is your imei backup file) copy and rename the .nv_data.bak to nv_data.bin and set permission and change owner.
.nv_data.bak.md5 - (delete this file first)

Fixed permission.
I found one .nv_data.bak dated year 1994 , which I think came in when I was trying to flash some efs fixes i found in XDA.
Without much hope I tried what you said, but still nothing happened. IMEI blank, baseband unknown.
Is it possible to have the mobile phone repair shop with RIFF or Jtag or some box thingy to have this done?

i think you must change the motherboard

Mate, do you like JellyBam V.1.3.0? Because that's the only Nandroid backup i have in my phone. I was thinking to upload it to my Box account for Emergency Backup if i don't have my computer. If you like, i can upload it for you, but the size of the backup would be nuts, it's 850 MB. It's up to you.

a friend of mine ran through the same same problem and i think he did some sort of repair from a shop but later we came to know that the backup can do the task not sure whether that work or not but u can give it a try,, BEST of Luck with that..... Hopit Fix the Issue

Good luck sir! As far as I know, if you would choose to replace the motherboard from repair center, it would cost you more or less 80% of the original price of the phone. So it would seem that you have to buy a new one. I hope that a nandroid backup (as stated above) would solve the problem. God bless you! Think positive

i have the same problem and tried those solution the TS tested and still no luck, i wan't to try those nandroid backup but can't find any.

never thought deodexing gonna brick the phone.. ive deodex once without any problem.. without any doing backup before that.. lucky me.. huhu
try other people's nandroid and see.. i dont think it needs a specific emei or what so ever.. as long as its a backup.. goodluck..

the problem is we can't find someone to lend us their nandroid backup.

I did it!
Bro, try use Efs Pro, http://forum.xda-developers.com/showthread.php?t=1308546
Try the new version, you can choise Qualcom version, write you IMEI number, go back to initial and do NV Restore.
My SG Fit go back to life (after maybe 4 months with 0000000000000 Imei). :good:
I´m very happy
Hope it work for you! Good luck!

How to fix LG G2 with IMEI issue

Long story short, I bricked my lg g2 d801 after flashing twrp recovery and trying to flash custom rom. The phone would restart randomly. I had no connection and the signal bars crosses out in red. In settings most of my info like baseband, imei etc were missing. I was looking up and many people bricked their phones with no EFS backup to restore the IMEI. This is how I fixed my phone. This should also help people who have zeroed out IMEI after bad flash or whatever reason. But you should at least have IMEI number ready (from your box/ receipt or call t-mobile)
1. Flashed the phone to factory firmware using LG support tool. I used the following guide:
http://androidcure.com/unbrick-lg-g2-stock-firmware/
used the firmware: T-Mobile KitKat D80120A_00.kdz
there's also similar guides in xda, follow whichever you prefer. Goal is to revert the phone back to stock.
After flashing the phone, the phone was woking; however imei was null. In phone settings my IMEI was 0. To fix the null/bad imei follow this guide (Not all the steps are my work; this guide helped me http://forum.xda-developers.com/showthread.php?t=1942417 , also watched some you tube videos):
2. You need the following drivers and software:
LGUnitedMobileDriver_S50MAN310AP22_ML_WHQL_Ver_3.10.1
QPST_2.7_378
imei converter: http://www.sendspace.com/file/a3spfh
3. After installing the driver; turn on USB debugging and connect the phone to computer
4. Install QPST, run QPST configuration from from start menu
5. Click on Ports tab. Click Add new port. Your phone should be COM4/5. It will say USB after the port. Select the port and click OK.
6. The port should come up on active phones. Select the phone and and click on "Software Download" from start clients menu
7. Click on Backup tab. Your port should appear. Backup by clicking on start
8. Now go to Program Files/qualcomm/qpst/bin folder
9. Run RF_NV_Manager program
10. Click File read from phone. Your IMEI should appear on number 550; NV_UE_IMEI_I
11. In my case; there was no item 550 as my IMEI was missing. Don't worry.
12. Click on file> Read supported RF NV items
13. Now click on item 550. It should show 9 blank fields.
14. Start IMEI converter. Type in your IMEI in enter IMEI click on convert IMEI
15. There will be 18 digits in groups of 9
18. In RF_NV_Manager program; click on Hex by Write NV button
19. IN the 9 boxes; type in the numbers from IMEI converter starting from left. Type in first group of two numbers in the first field, then go to the next field and type in second 2 digits
20. After you fill in; click on write NV
21. Now click on File> Read from phone. NV item number 550 should appear now.
22. Unplug, Restart your phone and your IMEI number should be there and phone should connect to network.
Above process fixed my phone with full 4G LTE data. Now depending on the how bad your EFS was damaged; you might not get 4G lte data. But at least now; you will be able to send the phone back to LG for repair or return to t-mobile as IMEI number will be in your phone.

You can do this with EFS Professional. It does all the conversion for you and you dont need QPST. Just simply type in IMEI and write to device.

I've tried the this guide and it didn't work for me. I get an error when I try to write NV. The good news is that I don't have an immediate need to change/fix IMEI but I was wondering if it ever gets zeroed out I have a way to restore it. I will give your tool a try.

So the EFS Professional is compatible with phones other than Samsung? Once I've unzipped the file I see a bunch of binaries for Samsung phones, but nothing for LG G2. When I try to run it generates an error the app is for Samsung devices only... Where can I get a compatible binary for LG G2 or EFS professional that works with LG G2?
I've tried Qualcomm NV Tools instead of EFS Professional and I cannot create a backup. When backup is being created it errors out saying the device has been disconnected... Also if I write the IMEI it says it was accepted but it doesn't change.
PS: I should probably start screweing around with these apps since I may introduce the problem. My IMEI is fine.

Imei will only write if zeroed out. You are correct, EFS Professional is for samsung devices but the Qualcomm NV Tools is universal. I am currently in the middle of updating it so more features can be used on other devices.

Hey kingroach, amazing guide, wonderful!
I followed everything step by step. Right now I have some generic IMEI which does not work, I'm trying to write my original one back, but at step 20, when I click "Write NV", the numbers change, the Hex unchecks and the popup comes out. When I close it, Hex goes back to being checked and numbers return to what I made them. and I get this popup:
Here's a video.

Hi, thank you for your help too in these threads. I tried EFS Pro, everything checks out, it says IMEI written, but when phone is restarted, nothing has changed. Do you know if EFS Pro need some other setting enabled to actually change the IMEI?

Try deleting 550 nv item which contains the imei and save. Restart the phone and add it.

I couldn't - you try with the custom list, under tools I think. You move item 550 from the right column, and it dissappears, but when I read NV phone items, its there. It's untouchable I tell you!:silly:

thanks,i was able to change imei,but still can't register on network?any possible solutions?

Go to
Settings/Mobile networks/Network operators/Search networks
And choose your network
If didnt work try to flash your mobile with latest Rom using (smart switch) keep in mind you will lose all data on your phone if didnt work try Marshmalow beta....any way try roms and do same steps...

If didnt work take it to repaire to replace imei certificat with octoplus box or z3x pro box only 10 bucks or 20 you will not get original imei but you will be able to register then set back original imei with apps inside folder
Look you can find the download link

i can change imei easily with your instructions provided,but serial number? ( it works for me i can change my imei to whatever i want to....S/N is easy only modify serial_no file inside \efs\FactoryApp ) <<<<could you explain this? my emei seems to be finally corrupted so only way to get it back is write in id changer manually,so do i need to backup and restore it anyway?

Dude just restore this efs backup with twrp recovery https://www.mediafire.com/?loh80547x1k5cg8
It will say null or something then try to fix imei with apps inside folder...if this didnt work visit repair place...

Sincerely hope you're not in the UK as it's very illegal here to change IMEI and advertising the fact isn't a smart move.

Greetings,
Changing IMEI is illegal in many countries and the discussion thereof is prohibited on XDA.

Elephone U Pro IMEI and Baseband thread

Lost IMEI and Baseband on your U Pro.
lets search for a solution.
forword:
if we flash the 2080227 stock rom we will lose the IMEI and Baseband information in Settings.
the IMEI and Baseband is still there its just that it dont show in settings anymore.
Why:
stock rom 20180227 contains all images of the official Stock Rom as dump.
also modemst1.img and modemst2.img. in that images are the imei information stored.
baseband information is stored in fsg.img
but why it dont restore also the imei info in settings ? maybe its region related. we dont know that yet.
lets Discuss and find a Solution/fix for that

reserved
here i will post the possible solution ..............
1.
This will restore the IMEI numbers into settings for slot 1.
Slot1 and slot2 will be similar then.
1. Install xposed manager APK. You have to have root for that.
https://xposed-installer.de.uptodown.com/android
2. Download in the app framework v90.beta3 and install it ( all in the app)
3. Download this app from playstore (IMEI changer)
https://play.google.com/store/apps/details?id=com.vivek.imeichanger
4. Your imei is written on your u pro box back cover.
Enter the IMEI in the app. Save it and reboot.
Done!

can you maybe transfer from eragon rom thread to here the posts concerning imei?
thank you

LOL . I did not tested that.just uninstalled framework and xposed app and the IMEI is gone. You are right. WTF
In ~2hours I will know if the other fix I found will work

Maybe helpful information:
For me without any changings the IMEI isn't gone. With *#06# I see two IMEI
I'm on eragon 4 but I've had to make a factory reset after update from 3 to 4 (there were some problems like system settings not working)

I guess the problem of losing the IMEI was caused if someone flashed the stock rom 0227. It was overwriting modemst 1 and 2 where the IMEIs are stored. Eragon doesn't do that.

I have found appropriate tools (also via xda), which perfectly fulfill the task...
QUALCOMM smartphone write IMEI tool 1.01
QMSL IMEI and SN writer 1.4
But apparently the tools do not support the chipset, or I have not yet found a way to use the tools accordingly.
If someone has experience with these tools…
Thanks in Advance

Already tested them a few days ago. They don't work.
Feedback of my progress so far:
I use NV ram tool to try to restore IMEI.
I was able to build IMEI but it did not flashed it because of a driver (diagnostic mode) problem.
I just have to find the right driver. Lol.
Sound funny , but I have around 100 different diagnostic drivers for Qualcomm devices.. one is the right one I hope ....

all the best man to succeed, we are with you

Been looking through XDA threads hoping to get some ideas on missing IMEI thing. I'm also trying to run a NV Backup using the QFIL program and up to now I wasn't able to do that, the blue 'start' button was always disabled(diagonal gray stripes) with the COM port and diag driver ON. I think, the problem is related to the lack of IMEI/ESN etc.., because today I hooked up my spare Moto G4 Play and got the NV bckp from it. Then, after that, I actually had a little success with Upro, I used the same diag driver which poped-up with Moto, HS-USB 9091 (instead of 900D), it's also a Qualcomm driver, found it on my desktop(uncheck: show compatible drivers to see it) Not a total success but, at least I could start the bckp. It failed, still, I've never gotten this far. Can you try and see if you're able to get the NV backup w/o IMEI#?
Is there a way to somehow convert to text the .qcn files? How about editing it, if that's possible then the imei could be written into saved files and fed back into the phone using 'restore'. Just saying, am clueless on that.
Ok, here is that link from another XDA thread and you'll find two screenshots below:
https://forum.xda-developers.com/moto-g4-plus/help/diag-mode-g4-qpsd-t3591683/page2

https://drive.google.com/file/d/1xawPNNMCD39nzQJaoBfwwnf0zVFCwQTA/view?usp=sharing

I am ready to try the IMEI edit on my Upro. I was dry practicing today on .qcn files extracted from Moto 4g Play, navigating the .qcn with this editor http://mh-nexus.de/en/hxd/ , finding the proper columns and rows, playing with hex./dec. conversions guided by this: (watch?v=zn_D6TEFABQ)
But I'm still missing the most important element: the actual Qfil generated .qcn backup files from my Upro, can't get it. You guys have any suggestions?

Its a placebo fix or better only a solution for fake/anonymize the IMEI for apps only!
If the provider needs the IMEI to connect to his network it is not working!
With a app on phone you can not bring back the IMEI, its stored in the NVRAM.
You have absolut no write access to this "partiton" on a running system.
for real restoring you must flash it!
