I9000t ime

I had an issue after updating my Telstra branded i9000t from stock 2.2 dvjp8 to i9000xxjpy i had no phone service and no IME trying to restore my efs folder had no effect.

Reinstalling the telstra rom still failed to fix my problem.

The way i solved this was to remove the sim card delete the efs folder and then copy over my backup of the efs folder from my internal sd card using File Expert in root mode i also did the same thing with my csc folder then refit my sim card power up the phone problem solved.

Im not sure exactly what is different with the telstra i9000t in the past I have had many problems updating this phone anything from internal SD card read problems to failed boot loader update and no 850mhz mode tried all the fixes on xda for various problems I personally feel telstra has locked down the phone so much its just not possible to have 100% success and maybe the galaxy s or odin etc are not the most stable of platforms to work with in the first place.

I hope this information helps someone.

i had a problem with my internal sd, i sent it to service and got the internal sd changed for 130$. today i received my mobile, and recognized that the imei changed to fake imei. i had backups. i decided to use them with efs.tar method and with copying the nv_data.bin to efs folder, but none of them worked.

I will tomorrow again take the phone to the service with the backups of course, but because of i am in Russia, i think i will have some problems with the service guys.

Have any idea why i cannot restore it?

Regards
[Galaxy S I9000 Android Development] _murray_:
Yesterday i talked with service guy. They told me that they have changed the motherboard and the new mother board do not have a valid IMEI.

When i mentioned, it is not possible to use it in other countries, they told me that, i did not say them that i will use the telephone out of Russia. And according to Russian rules, it is forbidden to upload or change IMEI.

Is there any way to upload my old EFS back up to my phone with new motherboard?

Regards!

it's useful thank u
[Galaxy S I9000 Android Development] Candanga:
Sorry for the late reply, I've been very busy with work; nevertheless, here goes my best effort to your non-related-thread question :p

I'm afraid its not legal (anywhere I guess LOL) to change an IMEI. It is the Service Centre responsibility to make sure the MBs have proper IMEIs programmed as this are flashed from the factory line to the board (as you know they come with a sticker and fancy bar codes with version # and all of that).

Either-ways, I'm sure if its a certified Sammy Dealer they have the appropriate Riff-boxes to flash it back, which I don't know is a normal method. There's also the hypothesis that you got a refurbished board, which is a common practice in tech-support.

Cheers.

Hi

I tried to unlock my SGS 2.3.3 with SGS Unlock but something went wrong, and now the phone doesn't ask for pin.

I have a backup of my EFS, but when I replace the nv_data.bin, the phone always screws it. That's what I do:

1)Copied good nv_data to /sd_card

2)Deleted with Root Explorer nv_data, md5 and .bak

3)Copied good nv_data to /efs

4)also tried the chow 1001:1001 suggested trick, but nothing changes

Reboot , and I can't login in SIM. If I pull the nv_data from the phone, it's hex different from the backup.

I also tried to reflash original modem.bin, but no luck.

Now I'm lost

Please I need any help!! (getting crazy)
[Galaxy S I9000 Android Development] Rahulrulez:
Can anybody integrate the code in shell scripting and pack it as CWM?
[Galaxy S I9000 Android Development] Candanga:
Is 2.3.3 the original ROM for your SGS? Try going back to a stock Froyo or Eclair closest to your provider. Make sure you flash via ODIN all the CSCs or w/e the package includes.

Check your IMEI. Try the steps you tried again under Eclair/Froyo and flash back to your 2.3.3.

I have two Clean NV_Data files. (From my two previous Galaxy S devices) Can I interchange them with the current one i have without Flashing Stockroms or Kernels ? (I have root access, ADB and all that $$$ )

Im not asking for the legal possibility, Im Asking about the technical possibility. Will a new NV_Data file work without bricking/corrupting IMEI of my Device ?

Also I wanna restore my Existing NV_Data file when I want it back.

Thanks and Best Regards,

JazonX

[Galaxy S I9000 Android Development] ZeroPDA:
There is a mistake. tar says about invalid options

should be

tar Zcvf /sdcard/efs-backup.tar.gz /efs #yes, the letter Z should be capitalized
[Galaxy S I9000 Android Development] pepemosca:
So, is the same if I use ADB commands or Root Explorer to backup my /efs folder on my Samsung Galaxy S2?

Thanks!
[Galaxy S I9000 Android Development] pepemosca:
Bump!

Can someone confirm if it's ok to just do a RootExplorer .tar with the /efs folder.

Should I do something else?

I don't think it makes a difference, but i can't really confirm it ;)

Problems

Hi Thanks a lot for your tutorial. I have few questions! You mean I have to unzip the tar file and should copy only the nv_data.bin right?

If that's correct then I did and I'm having issues. When I run the above command without 'su' in terminal emulator I get,

Then I type 'su' and it gained root access. But this time I get different error..

What should I do now? I lost IMEI after installaing ICSSGS RC 4.2 and I want to restore it!
[Galaxy S I9000 Android Development] kathees:
I don't know what changed I tried again same commands it worked. I have my IMEI again!

Thanks for the guide!

[Galaxy S I9000 Android Development] jacobuscuracao:
it keeps telling me that the copy failed, many many times over

nitrality has a tool to restore /efs from backup, but that keeps telling me that it went OK but it doesn't seem to have worked

I'm root of course and EStrong file explorer and root explorer both get the same problem when I try to paste from a backup folder after deleting the wrong one
[Galaxy S I9000 Android Development] SGS_elko:
He Guys, here my story how I recovered my IMEI without ADB. Only with root explorer and terminal emulator!

The IMEI changed since i flashed JW6! But I was clever and backed up my efs folder a year ago. The backup was from the famous JPY (2.2.1) ROM.

Attention: don't do this if you haven't a backup of your efs folder!

1. I flashed back to JPY and wiped the phone because of many fc's. Rooted the phone with CF-root.

2. Copy the ziped efs folder (the backup) from my PC on the internal SD of the phone and extracted it with root explorer.

3. First I deleted the whole efs folder in the system root directory with root explorer and restarted the phone. After that when you go back to the system directory, there is a regenerated efs folder!

4. Delete in the regenerated efs folder nv_data.bin and nv_data.bin.md5

5. copy from the extracted efs backup the folder imei in the efs folder of the system root directory!

Then copy the file .nv_data.bak from the backup in to the efs folder in system root directory. It will ask you to overwrite the existing file and choose overwrite. Copy the same file again so that you have 2 copys of the file .nv_data.bak in the efs folder in system root directory!

Rename one of them in to nv_data.bin and the other leave as it was (.nv_data.bak). Close root explorer.

6. open terminal emulator and type:

su

chown 1001:1001 efs/nv_data.bin

Now exit terminal emulator and restart your phone. Your imei should be back :D. Proof it with *#06#

As you see the file .nv_data.bak is verry important, because it is the backup of the original nv_data.bin. If you haven't a backup of your efs it should go with the file .nv_data.bak in your efs folder of the system root directory (only if you did NOT delete anything from the efs folder before!!!). First of all you have to copy the whole efs folder on your internal SD card of the phone and do the steps I mentioned. Because if the IMEI changed after a wrong flash it didn't change the file .nv_data.bak ;).
[Galaxy S I9000 Android Development] dreamer94:
yeah.i faced with that when i was installing aokp m5 .but i now why my imei changed i tested it.i was flashed m5 over the stock rom with cwm3(cfroot).After i recognised my imei is changed to 0049.... ,i flashed stock rom (without restoring efs) and my imei was back.then i tried to install m5 over cm9,and it worked like a charm.

Anyway i also tried restoring efs when i was on m5.like you said when i delete main efs,it always created itselft and in efs there was a "lost+found"folder

Either way now i never flash any roms over stock.except cm9 the only rom that can install perfectly over the stock for me :)
[Galaxy S I9000 Android Development] skells:
Uhh i have a fake IMEI myself, but i don't have any problems connecting to 3G or anything. What should I do?

The above code worked for me.

Luckily I had a copy of the good efs folder.

Thank you sir..
[Galaxy S I9000 Android Development] Dingo_HR:
I can not delete efs folder with root explorer, also can not from aroma file manager in recovery.

UPDATE: I did made it to delete in recovery FM, but after restore folder is empty, what now ?

UPDATE #2: Solved by returning to stock GB and flashed different JB ROM

[Galaxy S I9000 Android Development] ficko_98:
This is i9000 thread, anyway you will probably get your original IMEI by flashing stock rom via odin, stock rom you can find on sammobile.com site.
[Galaxy S I9000 Android Development] gverma1:
If one installs stock ROM via Odin from sammobile.... and all people will use the same file from sammobile, will the IMEI be different or same on all those users' mobiles?
[Galaxy S I9000 Android Development] ficko_98:
IMEI will back to normal and ofc IMEI will be different to all people who installed it.

[Desire Q&A, Help & Troubleshooting] tucka20:
Hi, I am currently experiencing a wierd SMS issue on my Desire running Robo's HD rom 0.13. Lets point out first that my sms is fine, I can send and receive texts perfectly. Except for one contact.

Me and my girlfriend text a lot, and I believe my phone doesn't want me to. Whenever I text her, she texts back, and I go to text her back,it says message not sent. However, if I delete the thread (with two messages in) and create new message,it sends fine. Baring in mind we exchange around 100sms per day, I am having to delete the thread and create a new text message just to get one through, which is getting quite annoying. I shall just stress this is the only contact out of the 25-30 people I text regularly who I am having this problem with. The things I have tried are:

Deleting and creating new contact

Changing her number to various formats (+44, 44, 07 etc)

Reboots (many of them)

Changing her contact name

Different sms apps (chomp, stock, handcent)

Nothing has worked, and the problem still remains. I would really like this sorted, as it is getting quite annoying. Any help will be greatly appreciated.

First the good news.....

Samsung have put Asphalt 5 HD on the Samsung App list.

Now the bad news.....

1. It does not configure correctly to the Tab's screen size.

It displays in the top left side of the screen.

None of the radio buttons work because the screen positional data is incorrect.

2. It automatically Force Closes after 10 seconds.

Clearly whoever released this to the Samsung App list did not check it out on the Tab.

The version is 3.1.3 and that is not a Tab version.

EDITED:

Posted in error, sorry guys it should have gone into the Galaxy Tab section. Still unsure how it ended up here.

So...I'm planning on converting to amonra 1.8 (hopefully it's the latest version) and I was wondering about the nandroids that I made on clockwork. How do I move my recoveries from clockwork to amonra? Or how would I backup and restore my old nandroids with amonra? Thanks.

yes but how would I be ABLE to restore old nandroids with amonRA without having to keep flashing the recovery images each time?

:/
[EVO 4G Q&A, Help & Troubleshooting] hooover:
you would have to restore the back up then flash the alternate recovery and back up
[EVO 4G Q&A, Help & Troubleshooting] drmacinyasha:
Simple idea:

1) Restore Nandroid via Clockwork.

2) Use ROM Manager to flash Amon_RA.

3) Take Nandroid backup via Amon_RA.

4) Repeat as needed.

However, if you do something stupid which causes you to screw everything up (like using a Nandroid backup from another device), you're on your own.

5. Touch Access Point Names

6. Press the MENU key

7. Touch New APN

8. Touch Name

9. Enter Vodafone MMS, touch OK
