Hi guys!

After flashing custom rom my IMEI from my new S3 is lost. I have no backup of original efs folder, but i found efsbackup.tar.gz and efsdev-mmcblk0p1.img.gz on my sd card. Don't know what made them appear there.

When i follow the steps by threadstarter - I can't delete efs folder. Inside my efs folder there is nv_data.bin, nv_data.bin.bak, nv_data.bin.md5 beside some other files, but no .nv_data file.

Also Ktool is not working on S3. What can I do? Any help is greatly appreciated. I have Root explorer and Terminal running on S3.

Thank you!

Check this thread out..

OP is active(online now) and might help you...

http://xdaforums.com/showthread.php?t=1308546

and were you using siyah kernel because I have heard it backs up the efs folder automatically..

Not sure though..
[Galaxy S II General] innahouse:
Ok, I just renamed that efs folder, that was possible..then I did reset the phone, instead of .nv_data i used nv_data.bin.bak . copied them into the efs folder two times and named them nv_data.bin and the other nv_data.bin.bak

After that I started terminal then su then chown 1001:radio /efs/nv_data.bin hit enter.... then I did reset the phone...still my imei is gone

what can i do now?

EDIT:

SORRY, I was wrong, Slim ICS is using 3.035-Siyah-s3-v1.2.6 kernel

thank you for that, I will try it, hopefully i can restore my s3, no fun to lose that money on that one :(

EFS Pro also could not restore my IMEI . . .

damn, is my ****en s3 completely broken?

[Galaxy S II General] Osutin:
Will this method help restore the IMEI on a phone who's IMEI has been completely destroyed? I recently had to go through hell to get my phone in a reasonably working state, and during this hell, whether it be at the very start or somewhere in the middle, my original IMEI was completely destroyed/lost, along with my EFS folder which contained the following (empty) folders: "bluetooth" & "wifi". I got help from someone, and now I have a generic IMEI that doesn't randomly disappear, but is it at all possible to recover my original original, or is there no known way (ie, I'm screwed)?
[Galaxy S II General] darlidar:
no files in efs folder

hello,

i do not have any files in my efs folder, and i have no backups,is there anything that remakes the efs folder and the files in it?
[Galaxy S II General] cdaarif:
Same problem.
[Galaxy S II General] trilok31:
i tried it but still have the fake imei number i know my imei number how can i manualy change it
[Galaxy S II General] AlwaysDroid:
This guide worked great for me, and I used it on my i9000. Thanks a ton :)
[Galaxy S II General] ZRong223:
When I copied efs folder, I put in external sd. Then copied another one at desktop. I deleted the efs in external SD. Then I deleted original efs in root section and restarted the phone. Android then auto generate the folder.

But when I looked back to desktop, I realize PC didn't copy the hidden files!!! OMG!!

The key file is hidden one.

Then I stopped. I know I failed...

Is there any solution? T.T
[Galaxy S II General] AlwaysDroid:
Not sure if its the same for galaxy s2 but when we flash back to froyo or gingerbread our imei gets properly regenerated. Then copy /efs and go back to custom rom!
[Galaxy S II General] ZRong223:
Can you give me a full tutorial?

Or some steps before following the 9 steps?

I am currently on the fake IMEI, that means the "bad" efs folder.
[Galaxy S II General] AlwaysDroid:
Okay,

0. Do a nandroid/titanium backup

1. Load Odin with a GB firmware

2. Flash it however you do on an s2

3. Wipe data/ factory reset from stock recovery.

4. Boot into the os and see if you have your imei. If you do, do a couple victory laps around your house doing your happy dance and screaming "victoryyyy!"

-If it doesn't work I'm really sorry, it was worth a try though.

5. Root the firmware with something like superoneclick so you don't have to flash again.

6. Download a root file manager. I use "file manager" by rhythm software.

7. Copy your /efs to your sdcard of computer.

7b. Only restore with this method if needed.

8. Do another happy dance just for show and post it on YouTube so you can get famous from messing up your phone. Then you can get money so that you can split it me, cause without me you wouldn't be famous.

9. Profit.
[Galaxy S II General] ZRong223:
Don't you think that I need to follow the 9 steps after step 4?

Ok I reached GB now, but sadly IMEI didn't come back...
[Galaxy S II General] AlwaysDroid:
It wont work if you have a valid backup of your imei, so no. :/
[Galaxy S II General] jalal.arkat:
my back up folder not have .nv_data only have .nv_data.bak
[Galaxy S II General] lyriquidperfection:
Install terminal emulator from the market place, make sure you are rooted with busybox installed, then type:

su

cp /efs/.nv_data.bak /efs/nv_data.bin

chown radio.radio /efs/nv_data.bin

reboot

Should restore your imei. :)

Worked great for me few days ago. Well done ;)

Samsung Galaxy Nexus restore IMEI help

Hi,

I have a Galaxy Nexus, I had my phone unlocked at a shop from o2 so it would accept my Orange T-Mobile Sim, a few weeks after i wanted to root my phone, I Successfully rooted my device, but It was locked to o2 again, I used doCOMO V3.1 to unlock my device and it ended up giving me that fake IMEI that you were talking about and locked me out of every network.. i tried getting my phone flashed, that didnt work, so i tried restoring my phone, then re unlocking my phone with doCOMO. it ended up giving me a IMEI that recognised o2 but nothing else. the IMEI for this is 351554052322998. i want to get my original IMEI back and restored on my phone. im a noob, could you provided me with a step by step guide with links to restore my IMEI. i would really like your help on this cuz you seem to know what your talking about. i will provide you with ALL the info you need on this matter.

Thank you

[Galaxy S II General] NoP_Compiler:
Hi.

After reading this thread, there is something I'm not getting.

I bought a SGS2 with Android 2.3 and updated via OTA to ICS...

Then, I installed CWM and flashed Cyanogenmod9 nightly... and I never made a backup of the IMEI / EFS...

After flashing CM9, I issue an *#06# and I get the right IMEI number (it's in the phone box and below the battery)... so it seems that CM9 didn't crushed the EFS folder... I don't understand why flashing CM9 preserved my IMEI... maybe CM9 zip installer preserves the folder before formatting / ? Maybe EFS/IMEI is located in a different partition that CM9 does not format?

What's the point I'm missing?

PS1: now that my IMEI is OK... which folder/files must I backup to preserve that info?

PS2: Can't the IMEI/EFS files can't be regenerated if you know the IMEI? (it's both in the phone box and below the battery).

Thanks.

Tried it, but my IMEI is sometimes appearing then becomes blank again. Wait for sometime IMEI appears again. What's the problem?
[Galaxy S II General] hy3na:
hey..somebody had the same problem like me ..no nv_data or anything else but .files , bluetooth , upgaddr and wifi folders in efs folder which are almost empty..i'd love to try gs2repair..but wifi isn't working...no signal no imei or imeisv (in status) no baseband,no bt no wifi ...this 9 step method seems the best but i don;t find the needed files to delete...anyway SORRY FOR BAD ENGLISH AND ALL..but i spent the last 7-8 h trying to find a solution ..my head feels like exploding..Sorry...so waiting for reply...oh ..maybe somebody can help me get gsii repair.APK file..for computer so that i could tranfer it on the phone...Sorry again..and thank you very much

ps: i still tryed the process and skipped the 4th step since i had no files to delete...and when i typed the adb cmd SU nothing happened ,no super user request

THX :d
[Galaxy S II General] bdkminang:
thanks. i new user on Galaxuy S2. That guide very helpfully for me.

:good:
[Galaxy S II General] remorema:
Its all good till step 3. I had to format efs with ktool to be able to delete it but when I reboot/reset after that I end up with only to folders in efs. Wifi and bluetooth. I never got to that standard imei allways get unknown imei and radio and the folder never recreates itself with more than that two folders. What can I do more?
[Galaxy S II General] frrustrated:
TIRED!

I tried all the little tools like gsii repair, hc ktool but they only seem to help restore the generic imei if you have non at all. Am stuck with it and after doing this on rooted ICS 4.0.3 (just thought i'd mention it in case its important) i get a string i don't understand in terminal. Any help with what it means or what i should do next? My imei is still the generic one 0049....:(

[Galaxy S II General] lyriquidperfection:
Seems you called the command incorrectly.

Type the following and it should work:

chown radio.radio /efs/nv_data.bin

Then restart your device.
[Galaxy S II General] frrustrated:
...

I tried but nothing. I tried with a space in the command between 'radio' and '/' like you posed but nothing happens. It just takes me to the next line. And when i enter it without the space, i get the same thing as above...any other ideas?
[Motorola Photon 4G] justindcarter79:
Can someone post the optimal handbrake settings for handbrake to rip movies to the photon. I ripped movies for my epic and they don't play now on the photon. I assume because of the h264 incompatibility. so for now what settings should i be using ?
[Motorola Photon 4G] mybikeisblack:
I'm also interested in this.

I use just the normal settings, but don't know if that's "optimal"
[Motorola Photon 4G] kennypow3rs:
Why not just use the evo 3D's settings for non 3D movies? Its the same 960x540 settings, same resolution, and same formats.

http://www.knowyourcell.com/htc/htc...deos_and_transfer_them_to_the_htc_evo_3d.html

These settings should be "optimal" for the photon.
[Motorola Photon 4G] Kcarpenter:
These should be known as 'the Photon settings' instead of the evo 3D's - because everything else is inferior.
[Motorola Photon 4G] justindcarter79:
I was putting full size hd videos on my epic and it would scale them down and it looked perfect. i am looking to keep the resolutions as they are so if i plug the phone into the hdmi it will still look great. those settings are way compressed and of not a good quality.
[Motorola Photon 4G] justindcarter79:
I am still having problems with playback on my photon that i had no problem with on my Epic. Can someone please help !? Search option is worthless it keeps giving me results for the xoom.
[Motorola Photon 4G] MultiDev:
You'll need to clarify your problem a bit more.
[Motorola Photon 4G] justindcarter79:
Movies that played on my epic will not play on my photon. when i rip movies on handbrake some will play and some won't. I am starting to regret getting the photon due to all the bugs with video playback ! I was wanting to know the settings i should use for handbrake but everyone short answers me and won't give the full rundown like bitrate container and if h264 is even compatible with this piece of crap phone !
[Motorola Photon 4G] Kevets:
The link posted above has all the information you're requesting. I'm not aware of the Photon scaling video on-the-fly and I doubt it'll work properly.
[Motorola Photon 4G] justindcarter79:
that is bare minimum i am looking for max quality
[LG Optimus 3D] N!ghtgold:
Thanks for the rom will test it out on my thrill
[LG Optimus 3D] kingfisher1111:
Thrill? Will this work on Thrill?
[LG Optimus 3D] noxxio:
oc possible?
[LG Optimus 3D] N!ghtgold:
I have gotten the other roms to work on my thrill. Example power froyo and kingdom 3d. The only thing I can't get 4g until someone pulls the radio off. I might try to get the thrill radio off tomorrow if I have time but yeah everything does work
[LG Optimus 3D] Meemo23:
Finally i see light at the end of the tunnel for our lg optimus 3d's thank you ThiaiZ..
[LG Optimus 3D] leekeithlee:
installing thanks
[LG Optimus 3D] malickie:
Yes it functions on the Thrill I Just installed it and so far no flaws. No OC ability, at least not on the thrill anyway. Regardless though nice Rom.
[LG Optimus 3D] N!ghtgold:
Installing on mine now.. Soooo excited
[LG Optimus 3D] ThiaiZ:
No OC guys. But even with all the LG stuf

it feels smoothier and faster than the other ROMs I tried before. First time I dont get laggs on LG UI.
[LG Optimus 3D] malickie:
Have to agree with you there, even without OC the LG Launcher which did Lag Slightly every once in awhile is now fluid, also like how you got rid of the AT&T Logo and have the droid guy as the battery meter. Now once this sucker gets GB and an OC Kernel than we will see some **** hit the fan lol. Anyway good work like that you kept it mostly stock considering for some reason I am not really a fan of the other launchers.
[LG Optimus 3D] wc326:
i was using the rom with arcura kernel.

and those 2 rom are laggy as hell.

did you manage to fix that?

thanks
[LG Optimus 3D] isaias19:
How to change the permission on es explorer?
[LG Optimus 3D] malickie:
So I noticed something with this Rom compared to Stock Rom on the Thrill. My GPS fixes position about 90% quicker which is a bit nuts actually surprised the hell out of me when that happened.
[LG Optimus 3D] abo_mara7:
Thanks for your work. That is what I really wanted:)
[LG Optimus 3D] PROTOCHIP:
Dear ThiaiZ,

Thanks for your efforts.

Just installed and it is really snappy but even if i try to change the ringtone it always plays the default one. Have u deleted the other tones or is it a bug? Thanks in advance...

Kind Regards,
[LG Optimus 3D] Claudio67:
Just installed and i have the same issue...

Anyway seems the rom I was looking for :-)

Performance pack should be installed?

Thx for your work!
[LG Optimus 3D] PROTOCHIP:
Dear Claudio67,

I have just tried to set an mp3 file as ringtone but still plays the default ringtone alson even i cant set to silent so i am sure it is an annoying bug and hope to be fixed soon... Also i agree that rom is really lag free and seems so stable...

Kind regards,
[LG Optimus 3D] Cancel357:
I have this issue as well. I hope there will be a fix soon because this is a great rom.

Ive just updated from v1 to v1.2 and im only get 2600 on quadrant? when before I was getting 3600. Why is this? Thanks for the good work.
[LG Optimus 3D] abo_mara7:
Can I get the 3D convertor workign without the need to install v1.2? Like by installing an apk?
[LG Optimus 3D] ThiaiZ:
Hi mate. V1.2 like i wrote a few pages behind is more like a test for those who wanted to see how 3D converter works and dont have to flash a .kdz file, this is why I made a .zip. There arent tweaks or the apks are not deodexed or zipaligned and the kernel is stock, this is why you get 2600 in quadrant. New version is coming tomm if everything goes like Im planing, and its giving me around 3000-3200 in quadrant with stock kernel.Its very good.
[LG Optimus 3D] ThiaiZ:
You can try and post here the results. I havent tried.
[LG Optimus 3D] typhex:
hey thiaiz any eta on the new version? :D i am on 1.0 ... i am very excited
[LG Optimus 3D] discoferret:
Ok thanks. Look forward to the next one. When I get paid I will donate for your effots. :D
[LG Optimus 3D] ThiaiZ:
I think its ready. Just gonna test it until tomorrow cause i dont want to make another version because or any bug.Want it perfect this time so i can start to work on kernel.
[LG Optimus 3D] abo_mara7:
I tried to put HRZ.apk & HRZ.odex in system/app folder, but it didn't work.
[LG Optimus 3D] ThiaiZ:
I tried the same but with HRZ.apk deodexed in V1.1 and didnt work as well. Something else than just the .apk.
[LG Optimus 3D] tiggerbcn:
This application has dependencies and needs the framework of the 10j, the framework is different than the 10e, why doesn't work.

the battery of this rom is so great.

i hvn't touch my phone in 24 hours + stil, have 80 % left
[LG Optimus 3D] DevJackey:
+1 this

my battery life improved so much with this rom.

Not sure did they make any changes or is the rom just void of any smoothness tweaks that uses up more battery.

But my battery has lasted much longer than normal, especially during time when screen is off.
[LG Optimus 3D] wc326:
at first i thought there were something wrong with battery status...

it stayed at max battery for like 12 hours.........i was like.. hmmmm another one of these rom lol
[LG Optimus 3D] DevJackey:
truthfully, i thought there was something wrong with the battery indicator too.

After a reboot, the battery was pretty much the same. And the phone was still alive after so much hours.

though, for you... 12 hours max battery? o.O that's awfully strange.

For me, its like... first 5 mins, 99, after 10 mins, 97.

after an hour, 90. then about 7 hours later its around 70
[LG Optimus 3D] jaikben22:
Indeed battery works is far better. who needs gingerbread lol. I hav a hd2 with 2.3.5 and I don't really see a lot of difference??

this rom is very smoot and very responsive
[LG Optimus 3D] abo_mara7:
I have a problem annoying me which is this message when I try to install some apps in the market: "This app is incompatible with all of your devices."

Anyone has an idea to get rid of that?
[LG Optimus 3D] Virtualizer:
I think I have to test this ROM.

My 2 year old HD2 with 2.3.5 is way faster and smoother than my new dualcore O3D :(

Where is the Tri-Dual Power?
[LG Optimus 3D] wc326:
this is the funny thing about android

single core system are mostly faster than dual core when it comes to UI speed.
[LG Optimus 3D] ThiaiZ:
Agree with you. My old HTC Desire is way smoother(UI takling) with new sense in it than our O3D or even my old SGS2.Is it for someone else or just for me , but does the camera take faster shots ? I mean it doesn open faster but takes faster shots ? BTW 1000 download just of V1.2 :D Me like it.
[LG Optimus 3D] ThiaiZ:
What SDCARD you have please?

ThaiZ my LG Prada camera app will not record video is there a fix also i dont see any difference in Sony BRAVIA engine also my LG Prada widgets are not working
[LG Optimus 3D] ThiaiZ:
-Nope, camera is how it is, use your O3D app to record videos or set resolution to 720x480 on Prada camera and it will work normally.

-Bravia engine depends from user to user, some say it works some not.

-There aren't Prada widgets in this ROM.
[LG Optimus 3D] -_-Help-_-:
ThiaiZ does your O3D sometimes stop keeping time, like for some reason my O3D's time will stay at like 2:39 AM and not run untill I reboot the phone.
[LG Optimus 3D] ThiaiZ:
No, haven't had this issue. Do you experienced it in any widget or statusbar clock?
[LG Optimus 3D] kylereid:
ThiaiZ, I don't want to stroke your ego. But you're the man! My phone hasn't run this amazing since i got it! Thanks so much!
[LG Optimus 3D] tampaboy1984:
I have experienced this issue with both the weather clock widgets. Also my phone gets really really hot while charging.
[LG Optimus 3D] mrbandwidth:
Do you use a task killer? If yes, exclude your clock process from being killed.
[LG Optimus 3D] ThiaiZ:
Thank you very much man, I do really appreciate that. :-)

Btw I set sdcardbooster script inside system/etc/init.d back to 128 or even 64 and it works very good. So what I conclude is that the value depends on your SDCARD, try different values to see what is better for your usage.
[LG Optimus 3D] sadegh1993:
hello

excuse me could you bring your ROM with v20e and GPU Overclocking ability?

thank you
[LG Optimus 3D] ishma:
I try change to 64, and yes it works, but the choppy not entirely gone.

it decrease the choppy a lot.

I had one little choppy sound after 5 song played.

btw, I wanna ask to you sir, is there any side effect to the phone performance if we change it to 64? because its so much less value than 1024..

thx..
[LG Optimus 3D] sketch2k278:
really great rom no major problems at all but I do have one issue whenever im on a browser, looking through my apps, playing a game etc. whenever I click the home button im always asked to choose my home app (like go launcher, adw, milocker etc.) Now is anyone else is having this issue? or could it be one of those apps causing it.
[LG Optimus 3D] cyclonmaster:
I leave it at default 1024. No problem at all here. Btw, I'm still on v2.5. Love it simple as it is.
[LG Optimus 3D] ishma:
this is not issue.

you can checked the "use by default for this action" and choose which launcher your prefer... and then the chosen one will be your default home screen.

if you want to change it, you can go to app manager and find your default chosen launcher and then you choose to clear default.

with this you will have to choose again among the launcher that you installed..
[LG Optimus 3D] sketch2k278:
that's the thing I do choose the launcher that I want to use by default but I still get that notification
[LG Optimus 3D] nanodigit:

It's you, sorry.

(Have you put the headphones on the radio? They're needed!)
[LG Optimus 3D] mrbandwidth:
Hey ThiaiZ,

I have noticed at build.prop (using ROM Toolbox) some values which are enabled and disabled at the same time:

user.feature.lgpoweroff = true

user.feature.lgpoweroff = false

user.feature.lgresource = true

user.feature.lgresource = false

user.feature.sui = true

user.feature.sui = false

dalvik.vm.checkjni=false

dalvik.vm.checkjni= 0

dalvik.vm.checkjni=false

(the last three at least are in concordance)

This is as intended? If not, which values are correct?

Tx,
[LG Optimus 3D] ishma:
If you still get the notification although you had the setting, I have not idea how to fix it.

Because it works fine with me..
[LG Optimus 3D] Kodaro:
Works really great and maybe even more smooth than 2.5 I think. But an issue from V2.3 has appeared again. After 1-2 days my WIFI won't work anymore. Handy needs reboot and then it's okay again.

Unfortunately you gonna have to extract the games from another ROM, cause as long as I remember I have always had them like this in my ROMs .
