I picked up a decent used SGH-i747 to use as a spare house phone. It was bone stock UCUFNE4, and I went through the rooting process, flashing TWRP, some custom ROMs, and restoring my nand backups. Yes, on a nearly decade old phone! I forgot how much I missed this phone after it took the splash.
DO THIS FIRST : Network / Carrier Unlock SIM
I was finally running my old system but then tried a Red Pocket SIM card...I didn't think ATT locked their SIMs. I don't remember having to unlock my old d2att, but I've slept since then. You'll most likely have to be on the stock OS to network unlock the SIM. *You get 5 attempts to enter the unlock PIN code.
Have your device and IMEI handy.
Follow the directions on ATTs unlock site https://www.att.com/deviceunlock/
Insert a non-ATT SIM card and turn on the phone.
After fully booting, enter 8 digit PIN unlock code you recieved from ATT.
If unlock is "unsuccessful", you'll have to go through extra steps.Extra Steps
Insert a non-ATT SIM card and turn on the phone.
After fully booting, cancel / dismiss the unlock code screen.
Open the Dialer and enter *#197328640# to enter the hidden Service Menu. If entering the numbers in the dialer does not open the hidden Service Menu, you'll need to return to stock firmware.
In the hidden Service Menu, navaigate to: [1] UMTS > [1] Debugging screen > [8] Phone Control > [6] NETWORK LOCK > [1] Perso Sha256 INFO
If the value for Sha256 is "0" and off, this is the problem why entering the 8 digit PIN code was "unsuccessful". We need to turn it on.
Touch your left capacitive Menu key opening a navigation menu, and touch the "Back" option. (not the right capacitive Back key, that will exit the Service Menu)
Select "[2] Perso Sha256 ON" (I'm not sure if it's actually on yet, or touching the item "Perso Sha256 ON" in the resulting cascaded menu turns it on, so I touch it also)
Touch your left capacitive Menu key and select "End" to close the Service Menu.
Reboot phone and now entering the unlock code should work.
Return to stock firmware
Assuming you have TWRP recovery version >= 3.0.2-0
Download bootloader-modem_I747UCUFNE4_4.4.zip to a micro SD card. (I've tried other bootloader-modem packages that didn't work)
Download I747UCUFNE4_Stock_Rooted_Deodex.zip to micro SD.
Backup or transfer to external storage anything you want to keep on internal storage. (*you might be able to skip internal storage wipe)
Make sure micro SD is properly mounted as portable storage in the device, and boot into recovery.
Backup system/data/etc. *optional
Wipe partitions: Dalvik, System, Data, Cache, and *Internal Storage
Install bootloader-modem_I747UCUFNE4_4.4.zip
Install I747UCUFNE4_Stock_Rooted_Deodex.zip
Reboot to system.
Root and/or flash TWRP with ODIN

Here is my SGH-i747 download archive. I never delete my shared files off Google Drive, so they'll be here. Everything you should need to bring this device under heel.

Hey, just want to say Thanks for this.
I had a Galaxy S III kicking around and wanted to put in back in action - just like you for a house phone. Up until about 1 year ago I had GBs of ROMs for the phone - and then did the housecleaning "Who will ever need this old stuff anyway???" and deleted the whole works. I realized the error in my ways when I started looking for the files this AM
So, you've got me back on track with your "One stop shop"
Cheers
PS. By the way - which of the ROM's did you find smoothest & most responsive to run?

Seems like custom ROMs for this device were better than other droids I've had. I think Liquid Smooth was the best performer, but limited to KitKat apps.

So, unfortunately I encrypted my phone. I didn't realize that you lose face unlock, pattern unlock and some other features.
I want those features back, but I don't want to lose any of my home screen setups, apps and app data. What is the right way to decrypt the phone and restore as-is. It's rooted, with CWM recovery and running stock 4.1.2.
Will Titanium Backup do the job and restore as-is after I decrypt my phone as decrypting it restores the entire phone back to default settings,
I want to make sure I get the widgets on homescreen features when 4.2 update hits, and I have a feeling they won't work with an encrypted phone.
Thanks for the help! =]
Yes, TB should work. Back up everything using TB, copy that to your PC, factory reset your device, copy the files back to your device and restore.

Alright cool, thanks! I noticed that I have to tap install for every app when I had done a restore for a friend. Is there any way around that? It's time consuming to have to press Install and Done for every app being restored.
You need to by the pro version for batch restore. Or buy another backup app like rom toolbox

Here's a post with some info on the decryption part:

decryption on android
You can decrypt on android without having to factory reset and losing data.
Follow the procedure below:
Go to settings menu >> select lockscreen >> select password >> type a six digit password containing atleast one number or as shown in encryption option >> now select security (it should be right below the lockscreen option) >> now select encrypt extsd or encrypt device (whatever you pressed while encrypting your device) >> deselect all the check boxes (not a single option to be ticked) >> press the continue button below >> press disable encryption >> you will be asked for password . Just enter the 6 digit password you recently set under the lockscreen option >> your device/extsd should get decrypted .
Works well for my galaxy tab 2 running jelly bean.
Pls report if it works or doesn't work.

It did not work as the encrytption option is greyed out and nothing pops up even if u click on it. I guess the only way is to take backup and then rest and then restore.
Works for me
Works for me (Android 4.2), I have the same key as lock and as encryption pw, so I am not sure which is which.
I have to enter the key after clicking decrypt and then click on decrypt again (to confirm the warning).
Device reboots and starts decryption process.

I am using a Samsung Galaxy Note. I just followed these steps and it worked for me. There is a crucial step. Selecting a password of more than 6 characters. First pass I tried a shorter password in the "lock screen" step mentioned above. However when I navigated to the Security page to choose Decrypt, that button remained greyed out. When I repeated the same steps with a longer password it was enabled.
Thanks for trying

Doesn't work on moto razr hd xt925 with stock android 4.1.2
The "Encrypt phone" option (under Security Settings), used to encrypt it in the first place, will be disabled no matter what I do from all you listed.
also make sure you have your battery at >80% and plugged in to a power source. on my galaxy S5 the option to decrypt was grayed out until my password was at least 6 letters and 1 number and my phone was plugged in and over 80%.
if you have met those requirements and still grayed out then not sure.

What I accidentally did was Encrypt my device thinking I was going to put a password on my phone so people couldn't get on my phone. Not wanting to have
to put the password in every time I looked for a way without resetting my phone. What you need to do is click on Device then to Lock screen. After an update the screen
password is now under that section and not Security. After clicking on Lock screen you can click on Screen Lock under Screen Security. There you can put in a different
password and then you can remove the password and now it wont be Encrypted.
One other things besides the password and such:
If you were forced to encrypt by connecting to you company email or something, make sure you disable it in device administrator (under the same security tab). If there is a device administrator enabled, it might be forcing encryption on (which will grey out or remove your decrypt option).
Of course disabling the device administrator for your company email or such will erase your emails on the phone but you can resync it once you install it again.
Just another thought since that was my case. I have to do that everytime samsung updates since it will only update when the device is decrypted.

Thank You!!!
I was getting tired of the tedious password prompt to decrypt my phone everytime I needed to use it. This actually worked.

So guy,
I've copied my files to SD card and have wiped everything.... After i have flashed a new ROM from my SD and it continues encrypted
Looking to disable encryption Galaxy S5 version 6.0.1
Anyone know if there is a way to disable the encryption on a Galaxy S5? It has the latest version (6.0.1). I was attempting to add my work email account to my phone and
while doing so it popped up on the screen requiring the phone to be encrypted. However, either I didn't enter the information correctly or something, since I wasn't able to
view my work emails. I've since removed that particular account I added. Just looking now to disable the encryption portion and go back to way it was. Thanks guys
I ordered a Samsung Galaxy SIII (US-Cellular) on ebay and tried to follow the instructions below:
1. Type *#197328640# and it brings up the factory service menu
2. Select (1) UMTS
3. Select (1)Debug Screen
4. Select (8) Phone Control
5. Select (6)Network lock
6. Inside the Network lock menu, Pick option (3) Perso SHA256 off, Passed that is a screen that says something like "no options in this menu, current command is 11863", Wait for 30-60 secs, from there hit the menu button on bottom left of phone to bring up options, Select "Back".
7. The last command should have brought you back into the Network Lock menu, at the bottom is (4) NW Lock NV Data Initialize, Select it. You might be asked a saftey are you sure, some people not, after it begins that process wait a good 60 sec the reboot. Thats it! Phones Unlocked
Somehow the phone is not reacting on the USSD 'secret' codes. I can push the hash-button, but nothing happens. I found on a forum that I should root my phone. So I did through Odin. But superSU keeps crashing and I get the error: Security Notice, an attempt to access a secure area...
I don't really need a rooted phone, would be nice, but I would like to use USSD codes, like *#06# for example.
R530 is CDMA based and might not function correctly on TMo.
Also, USSD codes only work on TW-Based ROMs or stock. Root should have no bearing.

What you are trying to do is unlock the phone from US Cellular to use on T-Mo. If that's the case, you will have to downgrade the firmware to Android version 4.1.1. This does not require Rooting. You will see appropriate firmware on SamMobile.com. Try the same process after the downgrade.
Don't try the downgrade if you are on android 4.3. It will Hard Brick your phone.
Hello all
I own a N900T. The phone is completely unlocked (via a sim unlock code).
I Rooted the handset and then flashed a custom rom (Jedi Elite Rom).
It was working flawlessly on AT&T. It picked up LTE perfectly fine. It was sending and receiving sms/mms fine.
Made calls perfectly fine.
Recently, I did a wipe/factory reset (holding the volume up + home + power key) in recovery mode. Because I will be giving the N900T to a family member to use.
After the reset, I inserted a T-Mobile sim card. The phone then appears to say "not registered on network" when I try to dial out.
A friend of mine had informed me that I might have corrupted the EFS partition when I did this wipe/factory reset.
After reading through the forums, I've come to realize that I should have backed up my EFS prior to me installing a custom rom.
Is there anyway I can fix a corrupted EFS partition?
The handset is displaying the IMEI perfectly fine.
I have flashed it back to the official stock rom.
Still no luck...
Any advice/help would be appreciated.
This should help you.

If you can display your IMEI, then your problem is not a efs issue, do a factory odin install again, and when it does it thing, go back into the stock recovery and do a factory reset, it should work properly after those steps.
Thanks

The only other thing it can be is blacklisted from the carrier.
>> Blacklisted
Most likely the case. The OP has been ignoring me saying that since December, so that's probably the case.

I've tried doing a clean install through Odin and that does not solve the problem.... (I recently downloaded Android lollipop for the N900T)
Wipe in recovery still doesn't solve the problem.....
The IMEI # is not blacklisted... So no need to make the assumption...
Well, you never replied to my posts asking, so you can't blame me for assuming that.
Try this.
- Dial *#197328640#
- Press Menu -> "Key Input" -> "Q0000" (Q and then zeros; no quotes)
- Wait a few seconds for the menu to change by itself
- Press "UE SETTINGS & INFO"
- Press "SETTING"
- Press "SYSTEM"
- Press "NV REBUILD"
- Press "ALL"
- Reboot if it doesn't automatically; it's normal for it to take a little longer this time around

sir, your PM is full!!!!!!!!!!!!!!!!! clean clean clean
Quick back Story---
Just bought Phone
Rooted using Kingo Root
unable to get Phone to read my metroPCS simcard
Unable to enter download mode to install TWRP
Rear camera displays all black (if software does not fix its only a $5 part, so no biggy
IMEI Clean
So I've tried using RomToolBox, to boot into Bootloader, and it just reboots the phone (obviously I do not have TWRP on there, and idk if Odin counts)
I am pressing Volume Down + Home + Power
Back Lights turn on ...(Important no warning message)
Then I get an android on its back with its lid open
I press home key again and it opens the "Android Recovery Utility A3"
I have tried pressing the Volume up key directly after the Back lights turn on, and same thing... Also tried removing battery for 1+ minutes, no go.
Heres my about phone info, the build seems off, I think the previous owner may have install a custom Rom on there but no idea...
Model: GT-N7100
Android version: 4.1.1
Build Number: ALPS.ICS2.MP.V1.3
Custom Build Number: 1359719440
Edit: Thought I would Add, The phone is unable to connect to a mobile network. When I put my sim in, I can see my phone number, but it thinks im on Tmobile, and not Metro PCS. Soo, I figure my first order of buisness is to Root, Install TWRP, then Install a CM 13. Rom. I am able to connect to my wifi, and Im assuming that the actual sim reader is working since it is reading my phone number off of the sim card. But I figure if worse case scenario I can replace that sim reader. I am pretty confident that the previous owner ran into the bug when updating it fails to reconect to the network and gets glitched out, sold it to a local bodega, and Im lucky.
Added a Video of the issue im having full boot, including my root access, about phone, and the Lack of Samsung logo, and how Vol Down Home and power bring me to Recovery mode.
Please close this thread, I just realized I got conned. This phone is a Fake Note 2. 2 gigs internal space etc... fml.
After having a great deal of trouble getting my phone unlocked I've decided to post a short how-to in the hopes that I'll save some people from the same aggravation.
This was on stock Samsung ROM, and of course your IMEI must be clean. You will also need an active SIM card from another GSM carrier that can do LTE/4G.
First, go to the AT&T Device Unlock Portal and go through the steps. I didn't enter my real name. It's an automated system that will email you the unlock code.
You should get an email from AT&T fairly soon. It will have a link to check the status. Follow the link and if the status is complete you'll be shown the unlock code for your phone. Write it down if you're viewing this from the phone.
Shutdown your phone, open it up, remove the battery, and AT&T SIM. Put non-AT&T SIM in, replace battery and close it up.
Boot your phone and you should be prompted to enter the unlock code.
If the code works, then it will take you to the home screen and in the status bar it should not say there's an invalid SIM.
If the code does not work, then hit dismiss and do the following:
Dial *#197328640#
Tap the following: [1] UMTS > [1] Debugging screen > [8] Phone Control > [6] NETWORK LOCK
Tap [2] Perso Sha256 ON, and wait about 30 seconds
Reboot the phone.
You should be prompted for the unlock code again. Enter it and it should work this time (you should not see an invalid SIM icon in the status bar).
I'm anything but a phone expert so if these steps did not work for you, then I probably cannot help you, sorry.

What you linked was actually the very first thing I tried. However, the [4] NW Lock NV Data INITIALLIZ option was not there for me. It was RAT FREE SUPPORTING or something like that. The steps I posted were what worked for me.
