I own a SIM locked Tab from Bell Canada and I'm working on unlock the SIM lock. I just used Z4root get the root privilege and was about to use RootExplorer to backup the /EFS folder to a microSD card. But the RootExplorer didn't show any file under the /EFS folder. I rebooted and checked again, still nothing in the folder.
ROM version: P1000XXJID
So what's going on here? Can anyone offer some suggestions?
Thanks in advance.
Was this an out of the box new tab or used? The empty efs folder is evidence of someone trying to avoid the t-mobile redirect when using the internet.
Go to settings> about device> phone etc and see what your serial number and IMEI number are.
Thanks for you response captain.
The tab is a sealed one (it's from authorized bell retailer), but the store claimed they got a batch of tabs with phone function (could be pre-flashed to some euro rom??). Just checked the SN and IMEI, they all match to the label on the back of tab.
The baseband version is P1000XXJID, don't know if this is the one for bell canada.
Well, don't worry, I deleted everything from that folder and I am in good shape. At least you have your serial number and IMEI.
Other than a blank efs folder, is everything else ok?
Captain, everything else works in the way as they should do. But I cannot unlock the SIM lock until I modify nv_data.bin file under the /EFS folder, can I?
So under this circumstances, how can I perform the SIM unlock?
Put in a sim from another carrier and see what happens - my guess is it's already unlocked. Anytime you use another sim you have to change the apn setting. That's in settings> wireless network> mobile network settings>access point name. If you don't know the particular details (approximately 14 entries), search xda for it, or google it. Usually I get lucky and the settings are already there when I go to change them.
Captain, I entered *#7465625# and it says Network Lock is "ON". I've searched everywhere....ahh, drives me crazy...

The proof of successful unlocking is putting in another brand sim and having the tab connect and run on the other company network, not what some setting says.
First of all, make sure that your device is rooted, after this install from the market: superuser, busybox & super manager.
Open super manager and give them root access in settings. This worked for me.

If your /efs folder "appear" to be empty it's because you do NOT have root privileges. The files are there you just can't see them.
You need to root your tab b4 anything else.

He already has root and installed Root Explorer.
I think you should put in another carrier's sim card and verify lock/unlock.
Cromed makes a good point. Is Superuser installed? And have you installed the latest busybox from the market?
I put in Rogers SIM card, the tab asked me for unlock code after bootup. I dismissed it and then the tab only allowed me dial emergency numbers.
I switched back to Bell SIM and using z4root to unroot and then rooted again. The root explorer still couldn't find any file under the efs folder.
P.S. I have installed both superuser and busybox from the market.
Captain, do you think it is possible that the retailer deleted the nv_data.bin file? It was quite suspicious that he mentioned of "official unlock service is available for $60". Assume they delete such file makes us no way to unlock the tab but pay for an "official service"...
And the tab comes with firmware with phone function which is supposed not available on Bell tab? Is P1000XXJID an euro firmware?
I'm sure that's what happened. I saw somewhere Roto sent someone a blank file for them to edit. Maybe search the forum. Have you flashed any rom yet? I deleted my efs folder contents and now files are in there.
Captain, I have NOT personally flashed any rom. Maybe i should re-flash the tab. Anyway, thanks for your help.
I just backed up my efs folder, then flashed Roto JMG, the full install, which wipes your sd card, and the efs folder had all the usual files and folders.
I would flash, because you don't need to be unlocked to do that.

The files only show up when you use a file manager with root access enabled. I had to download Super Manager (free) and give it root access in its settings and then I could see them.

From the op.
Hello all. I have an S 4 Active by AT&T. It has been rooted by GeoHot's URL. I then installed SU and ES File Explorer. I'm trying to figure out a way to get Tethering to work. One of the suggestions was to pull a custom TetherProvisioning file from a guy from YouTube whose name escapes me at the moment. Then, change permissions on the file, go to settings, then turn it on, get the temp warning, then you're good.
The problem is that I'm unable to change permissions on the file. I've verified the phone is rooted, but not sure what step(s) I might be missing. I went into ES File Explorer's menu and changed the file system to rw instead of ro, but not getting very far. Tried using ES and SU and no joy.
Any/all help would be extremely appreciated.
You have to change the permissions on the specific apk I assume you installed. I have root explorer, not es file, and I just long press the apk and a menu comes up where I can change the permissions.
I cannot access the service menu. I went to efs, then carrier, and changed from OFF to ON using all caps, but still get nothing when I press *#0011# on the dialer. I'm on MJE running cleanrom 1.5. Any ideas?

I just tried and works here. Am also on cr 1.5.
1. Did u reboot?
2. Did u go back and verify the edit to ON stuck?
♢NoteIII♢
I was having trouble too.
1.What are you using to edit the file? I recommend Root Explorer and edit it with text editor and save.
2.Once saved, close out editor and reopen file to make sure it saved it and "stuck"
3.Reboot you phone.
4.Open browser on your phone and go to forum page with the codes on it. Copy the Service Menu code to the clipboard.
5.Open dialer and press and hold in blank area to show option to paste from clipboard. If you did everything right Service Menu will popup right away.
i noticed for whatever reason on my Note on the MJE update if you direct dial the code it doesn't work for whatever reason. Copy and pasting the code is no problem.

First I used solid Explorer, then root Explorer from rom toolbox but it had already stuck. I did reboot,and checked again and it Did stick. I tried Copy and pasting but it didn't work either.
Could this be a Verizon model issue?

Now I can install .apk files from Chrome/Dropbox /es file explorer!!!!.................So I did this by accident I was trying to mess with the keyboard setting in the root folders and I got a setting popup.
1. You must have root
2. Es File explorer / turn on Root Explorer
3. navigate to /Device/System/app/
4. all I did was click on BuellerIME.apk and a pop up settings menu came up, from there a settings menu with unknown sources in it appeared. I checked unknown sources and that was that
anyone else confirm ? i only ask because i am on my second ftv ( bricked the first one some how )
Just tried it an it didn't work for me. When I launcher the app it only gave me the option to "Install" and said "Would you like to update this system application..." so I backed out. I'll stick to the other method.
It didn't work for me either. After I clicked the settings, no further menu appeared so that I can't check unknown.
I use the app root explorer, root permissions on and show hidden folders, but can not find the carrier folder.
This is because it is a terminal factory released?
I need to activate the hidden menu that is in the folder carrier
Is there anyone who knows about this?
