[Galaxy S II Themes and Apps] pinsb:
Just generates a generic IMEI, I suspect you'd have to restore other files in the /efs directory as well to get round the problem....the md5 file is one that immediately springs to mind.

If someone is willing to let me have a complete copy of their efs folder I'm willing to test it on my phone and post the result here. But frankly I'll be amazed if this is as simple as copying a folder.

My guess (and it is a guess) is that during the bootup process a GUID of some kind is generated against say the mac address of the network interface and the bluetooth interface (but frankly could be numerous other devices and/or the serial number if it's hard coded into the phone anywhere) this then generates a key which generates a validation value against the IMEI in the nv_data.bin file if the value doesn't validate then it installs the generic IMEI value.

However reading things elsewhere regarding certain boxes if they really can re-program the IMEI to anything of choice then it really will just be a matter of cracking the nv_data.bin encryption system to be able to generate any IMEI you wanted.

For the avoidance of doubt I'm not advocating anyone changing their IMEI, but I find it an interesting intellectual exercise.
[Galaxy S II Themes and Apps] lyriquidperfection:
Mac addresses are also stored in the efs folder. ;)
[Galaxy S II Themes and Apps] HellcatDroid:
Copying the EFS of one phone to another results in the generic 0049.... IMEI and the usual broken things AFAIK.

No matter if it's a good copy or a corrupted one. There is device specific / unique keys used for crypto in the nv_data.bin, like serial no. and such things, I'd guess.
[Galaxy S II Themes and Apps] pinsb:
That's what I'd suspect, but reading elsewhere there seems to be a box that can program a new IMEI code onto a SGS2. However I don't know if it's true or indeed if it works.

I don't want to post the name of the box on a public forum but I'll PM it to you.

Hi, I am trying to do the clean and raw commands in terminal emulator, but I their not working, and I can't seem to see what I am doing wrong, could some one help me please. I have attached screen shots of the terminal emulator.

Thank you very much :)
[Galaxy S II Themes and Apps] zrzhu:
A very good guide.
[Galaxy S II Themes and Apps] ithehappy:
Yes, but you need to create 'efs' folder to complete the terminal process successfully. However I heard for some people it worked without creating the efs folder!

[Galaxy S II Themes and Apps] gixie:
I was getting errors when run in the terminal and I checked them out and figured it was an argument problem.

The code below

Clean :

su
busybox tar zcvf /sdcard/efs/efs-backup.tar.gz /efs

should be

Clean :

su
busybox tar Zcvf /sdcard/efs/efs-backup.tar.gz /efs

Notice the capital Z in the list of arguments passed to the tar command.

I was looking at the error and noticed invalid argument and then the list of possible arguments among which I saw the Z argument with a description next to it: Z - (de)compress... (don't remember the full description).

I ran the command like that and it worked for me. I had a 20Mb file on the card.

Mods and OP feel free to correct me if I am wrong (also, please PM me if I did something stupid).

I had a backup already with Ktool, but then again...one cannot be too sure.
[Galaxy S II Themes and Apps] HellcatDroid:
Depends on your build of busybox.

Most busyboxes use the lowercase "z" for compression, some use the uppercase "Z", and some others take both and treat them equal.
[Galaxy S II Themes and Apps] gixie:
Hi Hellcat,

..and thanks for the reply... My god...you're a God on this forum...

I was reading about my SGS2 and found out about the horror stories with people that erased the efs folder...

I actually have the latest version of busybox, downloaded it yesterday, so people that read the guide and follow the instructions will most likely have the same version.

Just my $0.02, maybe the OP should update the 1st post, because I was not the only one to complain.

I'm by no means a linux guru, but as far as I know commands are case-sensitive, which brought me to my "discovery".

Thanks for the Ktool I backed up my efs folder with it ;)
[Galaxy S II Themes and Apps] ehknaton:
Try issuing the commands without the words "busybox"; like this:

tar zcvf /sdcard/efs-backup.tar.gz /efs

Also described here: http://xdaforums.com/showthread.php?t=859914

Goodluck
[Galaxy S II Themes and Apps] scandiun:
This is because moving from ext4 filesystem to vfat (called fat32) just blows the folder permissions, that is very important under Linux - Unix. You should tar the folder prior to copying it.

Check if the files are 0 bytes. Otherwise it may have skipped the warning and do it anyway.

Because Root Explorer has kinda of symbolic link following. Try instead Total Commander and enable Administrative functions in settings (you need root). Then you will see filesystem as it is, showing corresponding symbolic links with -> symbol.

If using Root Explorer look recursively into /dev/block/ and you will see related devices.

Yes, the operator > pipes it to standard / error output or a file overwriting it. If using >> instead just binary appends.

i cant take my phone to samsung service centre if i backup EFS?

Why back it up?

Well, let’s resume it saying that backing-up this little folder will keep you away from Samsung service centres.
[Galaxy S II Themes and Apps] tofupekoni:
The version of busybox that i got has been compiled w/o bzip or bzip2 function. So it gave me an error about the "z" in tar -zcfv. I did pack the backup w/o the "z" option and gave the file the name *.tar. I think its ok, is it?
[Galaxy S II Themes and Apps] portalgod:
If we are worried about permissions preservation, why don't we do tar -pzcvf instead of tar -zcvf?

after reboot, my device is hang on the HTC logo~~

i try to restart, but no work!

i still can go in REcovery, so what can i do now??

PLEASE! i need help!

T.T
[Desire HD Q&A, Help & Troubleshooting] Mr_JMM:
If you made a backup (using recovery or ROM Manager, use recovery to restore it.

If you didn't make a backup (silly) then...

If you can get to recovery, put a ROM that you want on to the SD card and use recovery to install from sd card.

If you don't wipe and it works you may not have lost data.

Did you try to flash a radio by using recovery? You shouldn't do that.
[Desire HD Q&A, Help & Troubleshooting] crossrt:
ok~~ i try to restore to official rom...

CM7.0.3 nid pair with wat radio?
[Desire HD Q&A, Help & Troubleshooting] superstick1:
Hi crossrt

Did you do a ENG S-OFF?
[Desire HD Q&A, Help & Troubleshooting] crossrt:

thx guys~~ i can start my device normal with restore to official rom~~

i think i should learn more something in XDA...

[Desire HD Q&A, Help & Troubleshooting] superstick1:
Haha. No worries dude.

If you want to flash any radios, make sure you have ENG S-OFF. Else the flashing process will not work.

Cheers. =)
[Desire HD Q&A, Help & Troubleshooting] crossrt:
but i had flash before with ARU Wizard~~

it is work and no problem...

but this time...XD

make me really scare~~

haha~

is tat ENG off is better?
[Desire HD Q&A, Help & Troubleshooting] superstick1:
Erm.. nothing is better. It is just another form of HTC security that we need to do it. Doing a Radio S-OFF only meant that we can flash custom ROMs. Doing ENG S-OFF together with Radio S-OFF now meant that we can flash anything! haha.

Practically nothing much left after doing these two things.

By the way. please mark this thread by editing it to [SOLVED] since you have already solved your problems.

[Nexus S Q&A, Help & Troubleshooting] reapur:
Hi,

I can't find an answer to this question, maybe I don't know what to search for.

I have a new Nexus S that is rooted with CM7.0.2 and Clockworkmod recover installed already, as well as ROMManager (I've already had it d/l 7.0.3)

I see that CM7.0.3 is available, and I read in the comments that a wipe and a dalvik wipe are recommended.

I'm up to date on my backups with TB and Mybackup pro, but I just wanted to know if these updates will reset the phone to an initial state or not.

thanks
[Nexus S Q&A, Help & Troubleshooting] buachaille:
It does not bother me but it will bother others, so I'll tell you. You should have posted this in q&a. Easy mistake to make though, but I bet you get some grief for it :D

Anyway, you need to wipe data, cache, and dalvik cache before you flash, but this will not delete all your personal stuff on your sd partition. You will still have all your folders containing pictures, music, etc. It will not be like going back to when you bought the phone. Nothing like it. And if you have a TB backup then you're cooking with gas. Just tell TB to restore all missing apps or restore all user apps. Do not select the option to restore system data. That brings system info' over from one rom to another and can cause problems.
[Nexus S Q&A, Help & Troubleshooting] reapur:
Thank you.

My bad. I had the General section open in another tab and I just overlooked where I posted.

Please go easy :)

[Nexus S Q&A, Help & Troubleshooting] buachaille:
you wont get any strife off me anyway :-)

Does that help. You know what you are doing with this now?

If you are on 7.0.2 then you should be fine going to 7.0.3. But don't go from any other build of cm7 to 7.0.3. I don't remember the details, but apparently it causes problems.
[Desire Q&A, Help & Troubleshooting] fabulous69:
Hi all

I have changed the screen of my HTC Desire (so had to opened it)

I replaced it, re assembly all the phone without doing it fast to avoid to kill some piece of other stuff.

When everything is done, the Desire can be put ON, i got the HTC white screen with the vibration

The phone took 2 minutes to show me a black screen with a phone into a green circle.

I flashed it with the RUU, (fastboot USB works) he rebooted after installation.

Same white screen, and after a few minutes, the HTC quietly brilliant screen appears, but the letters were very very very laggy.

Now, it is stuck on this image and i dont know what to do

I suppose if i had damaged something, he couldnt works no? usb is ok, fastboot, installation of RUU...

I'm scared having killed my Desire (the operation was risky but a really payed a good attention when disassembling and assembling.)

Thx for help

USB Ethernet for USB Tether from phone to Xoom

In the OP for the Tiamat kernel, BRD states that USB tethering has been implemented on 1.4.2.

I just made a USB host cable following this guide.

I also downloaded Gscript lite and tried to follow the few simple command steps in the referenced thread above. But.... nothing. It says, "Select a file ( .sh from sdcard )

[Xoom Android Development] Jewremy:
Okay...did you do ls /dev/block? That's where sda is. I'll write a script tonight.

Usb tethering has to be done from the phone side. Its meant for wifi xooms to get internet.

To get at your phone's storage, you have to enable usb mass storage from the phone.
[Xoom Android Development] cam30era:
I typed :

CD /dev/block

Ls

(Exactly as written in OP)

I do see the SD card, internal storage, and a lot of other stuff. But no sda1, etc. It seems like the two devices don't recognize the USB connection? But I was very careful to follow your fabrication directions.

When I tried to enable USB tethering from my phone, it says "no USB device connected ".

Thanks for your help.
[Xoom Android Development] cam30era:
How do you do this from the phone? I probably won't use it much as I'm primarily interested in tethering, but it would be a good test, and learning experience for me.
[Xoom Android Development] Jewremy:
It is android, right? Then there should be something in the notification bar. Try doing "adb devices" in terminal on the xoom while your phone is plugged in. Take a picture?

Host cable is plugged in to the xoom, right? Not the phone?
[Xoom Android Development] cam30era:
Yes, Android. Droid Incredible running Cyanogenmod 7.

There are no USB notifications in address bar on either device. But phone is charging.

ADB devices shows nothing when phone plugged in.

Host cable is plugged in to Xoom.
