So a lot of us have used THIS ( http://forum.xda-developers.com/showthread.php?t=2014982 ) method to unlock the ATT Note 2, and reported that it works, well, for me it "worked", it unlocked the phone but with a Simple Mobile and T-Mobile SIM it just never gave me access to the network, it connected to it but I wasn't able to make a call, only emergency calls. ( if anyone knows what I'm talking about and has a fix please let me know )
So I looked all over for a way to revert the changes done to the phone and was not lucky. I started playing with that Service Mode menu till I found a way to revert the changes, so I will post here the steps just in case someone wants to do that.
========================================
Do this procedure AT YOUR OWN RISK
========================================
I navigated the whole Service Mode menu of the Samsung Note II and finally found the option to revert the changes made to the phone.
Steps:
Enter the Service Mode menu:
Dial *#197328640#
//After keying the last # sign the menu will open by itself now follow this menu options:
[1]UMTS
[6]COMMON
[6]NV REBUILD
[4]RESTORE BACKUP
//There should be a written msg in the bottom that says "Golden-Backup exists..." after selecting this option the phone rebooted by itself and all the changes I did reverted back to how they were ( I did lots of changes trying to get this phone back to defaults but I logged all changes I did and they reverted after this )//
When I went back to this menu after using it, the written MSG changed to "Golden-Backup does not exist you man not use option 4-5" I believe that the Golden Backup is created when you do the first change on the phone using this Service Mode menu, I have not verified what I just said because I haven't made any change to the phone after this.

I wonder if it resets the entirety of the service menu? I just tried it The reason why I wanted to try this is cause I messed up something in there that didnt allow me to use the menu to change UMTS to EDGE and so on

I want this to be a thread dedicated to help others to flash the mentioned devices to Page Plus / Selectel / Next-G / Service in REAL 3G....
I have been flashing phones for a several years now as a hobby and want to pass on some of my knowledge and advice to others making this transition.
A few things I want to do when time allows as I work a full time job and have a family.. (Not to mention my Flashing Phone Hobby)
1. Keep a list of PRL's that work with Page Plus with no roaming symbol...
2. Maintain a summary of how to get into Diag Mode on all phones and methods to get your SPC/MSL on Sprint Phones......
3. Post useful Apks,, 16 Digit Passwords, and other instructions on flashing the phones.......
4. Maintain a Current List of Page plus Sids for Flashing..........
5. Make this a thread that people can come to and discuss issues etc....
Now I am not good at writing Guides and truthfully at this time have no desire to do so, but I will however try my best to help you along the way when my time is available. So please I ask do not flood my Inbox with request for a guide etc. (Post here so others can contribute and everyone can learn together)
One thing I have learned over the years of flashing devices is its better to think it through and work by trial and error so you can truly learn the skill of performing successful flashes.
(Please everyone keep it civil and make this a community effort to help each and everyone)
Current Status is that I can pull Keys/Passwords on Verizon S3 / S4 / S5 / Note 2 and 3, Sprint S2 / S3 /S4/S5 / Note 2 and 3, US Cellular S2 / S3 / S4/ S5 and Note 2 and 3 phones, Plus several other Phones and get REAL 3G with no donor on Page Plus / Selectel / Next-G....
(Again let me stress, please do not flood me with request to show you how to do this, as currently I will not post this information, I have my reasons and I hope you can respect that and use this thread for the other benefits you can get from it)
** Note: I did not include Verizon Prepaid or Straight Talk in this due to my beliefs that the cloning of esns/meids to obtain service is not LEGAL **

What is a PRL and what it does:
PRL=(Preferred Roaming List)
The PRL is a list of information that resides in the memory of some kinds of digital phones. It lists the radio frequencies the phone can use in various geographic areas.
The part of the list for each area is ordered by the bands the phone should try to use first. Therefore it's a kind of priority list for which towers the phone should use.
The PRL helps determine which home-network towers to use, and also which towers belonging to other networks to use in roaming situations (areas where the home network
has no coverage.) When roaming, the PRL may instruct the phone to use the network with the best roaming rate for the carrier, rather than the one with the strongest signal at the moment.
Since a PRL tells the phone "where" to search for a signal, as carrier networks change over time, an updated PRL may be required for a phone to "see" all of the coverage that it should,
both with the home network and for roaming.

Android 4.3 Upgrade Methods for Verizon and Sprint Phones
DO NOT DOWNLOAD THESE FILES AND ATTEMPT UNLESS YOU ARE 100% SURE YOU KNOW WHAT YOU ARE DOING
THIS WILL LOCK YOUR BOOTLOADER FOREVER NO GOING BACK TO PREVIOUS VERSIONS EVER
Let me stress that anytime you flash either with ODIN or normal methods you take the chance of BRICKING your device.
SO be sure you know what you are doing as I am not responsible for anything that may go wrong.....
These will wipe your devices and bring the phone back to like is what was brand new, and should not affect your flash, but then again do at your own risk.....
______________________________________________________________________________________________________________________
ODIN 3.07 Program to use for the Update: https://www.dropbox.com/s/zjw7zhr9br...Odin_v3.07.rar

2. Start Odin
3.At this point please make sure that ONLY TWO OPTIONS TICKED are "Auto Reboot" and "F.Reset Time" (otherwise you could end up with a very expensive paperweight)
4. Select the PDA button in the Odin program: Direst it to the tar file that you are using to upgrade the one you downloaded for your device......
5. Plug your Phone into the computer, wait for the drivers to install and then wait for the ID:COM section to turn blue in ODIN.
7.Press start and the flash will begin, once this has started do not remove the usb cable or turn off your computer or the device (or you will have brick for sure) the phone will reboot once the flash has finished.

Things Not To Do With A Flashed Phone
1. NO OTA Android Updates Period (You will break your flash)
2. No OTA Programming *228, *22890, *22800, *22801 or any other Variants
3. Some Rom's do not play well with Flashed Phones do your research before flashing.
4. Never do a RTN (Return to Network) Reset ##786# on a Flashed Device (Most definitely will break your flash)
5. Some Radios/Modems cause issues if you flash (If the phone is working leave it be)
6. Factory Reset ( I recommend not to do this also, some versions of Android phones it will break things period)
7. PRLS ..... aww my favorite, everyone thinks these are the answer to all their prayers
a. If the phone is working leave it be (my personal stance)
b. Some PRL's are not EVDO or have not been Modded and will break your 3G or throw the Roaming Symbol
c. I have posted many PRL's above that will work with 3G (Latest one I modded is 60007 for all carrier phones)
8. No Phone Number Change (You change your carrier assigned number, you must reflash)
_______________________________________________________________________________________________________________________
Why Is My 3G Data Slow?
It's a complaint I hear everyday from people using flashed smartphones performed by them or another flashing provider...
Why are my speeds so slow and is it possible to improve the situation?
There are a variety of reasons why 3G data speeds may be less than stellar, and each one requires a different solution.
Before assuming there's a problem, though, make sure you understand the realistic capabilities of your service.
VERIZON/Page Plus/Selectel:
2G 1xRTT: 50-100kbps download and upload with bursts to 144 kbps
3G EVDO Rev-A: (shows up as "3G" on your phone): 600-1400kbps download with bursts to 3Mbps, 200-800kbps upload with bursts to 1.8Mbps
(Don't get to caught up in running speedtest as these can be very confusing and fool you at times into thinking you have a problem when actually
the way they test and the servers they use get congested also)
POTENTIAL PROBLEM #1: Weak signal
If you're too far away from the tower (or if there are a lot of obstructions/interference between you and the tower), your device won't be able
to pick up a strong signal and your performance will suffer.
Solution: Try other locations in your home or area you are in, some areas do not get great signal strength and this could be your issue.
POTENTIAL PROBLEM #2: Tower overcrowding (Network Congestion)
The bandwidth available from a cell tower is shared amongst all the users connecting to the tower. A cell tower can only provide so much bandwidth,
and the more users there are connecting to the tower, the slower everyone's speeds will be.
Is this YOUR problem? If you notice that your speeds tend to follow a pattern most days (for example, nice and fast late at night or early in the day but slower in the evening when everyone is home from work and school) and you've confirmed that the problem isn't signal-related (by testing your speeds at home and then again somewhere closer to the tower), you'll know your tower is simply being used by lots of other subscribers at the same time.
Solution: Unfortunately, there's nothing you can do about this (other than consider switching to a different provider who might have more capacity at their towers or isn't as oversold in your area).
POTENTIAL PROBLEM #3: Incorrectly Performed Flash
It's very common for flashed phones to have been done incorrectly.
Is this YOUR problem? This is very possibly the source of the problem if your flash was done incorrectly or you made changes to your setup recently.
Solution: You'll need to either troubleshoot the phone and or reflash the problem phone.
POTENTIAL PROBLEM #4: Tower issues
Providers periodically do maintenance or upgrade work on cell towers, which can disrupt service; other factors like severe weather occasionally damage cell towers and cause problems.
Is this YOUR problem? If your service suddenly degrades significantly and doesn't improve much during non-peak hours (which it would if the problem was overcrowding), and you've confirmed it's not a problem with your flash, the problem likely lies with the tower. The best way to confirm is to take your device several miles away where you'll be connecting to a different tower and test there — if everything works fine when connected to a different tower, you'll know something is amiss with your home tower.
Solution: Out of your control, bear with it until the provider finishes work and repairs.....
Potential Problem #5: Sprint and USSC Devices
I hate to say it but I have seen some Sprint/USSC phones have this issue, likely due to weaker radios and or hardware implemented in the device.
Is this YOUR problem? This is very possibly the source of the problem if your flash was done correctly and you verify that other devices on the network in the same location as yours get consistently better data speeds.
Solution: Verify flash is correct and that your connected at EVDO in settings and passwords have passed authentication. If so this most likely a Sprint/USSC device issue out of control by the user. Replace device with another Cellphone Carrier brand and most of the time problem will be solved. (I see this allot with some of the Samsung S3 Devices from Sprint/USSC, almost like certain lots had a weak radio for whatever reason)
In the end your speeds can be related to any or all of these issues, and a proper flash is key to performing at optimal speeds.
Sometimes as much as we hate to admit a professional flasher is needed to correct speed issues, you would not believe some of the poor flashes I see when I read preflashed phones everyday that so called professionals performed
Definitely keeping an eye on this thread! Thanks Viper for putting this together. As a current PP customer with a Sprint GS3, I'm interested in learning more.
I personally used DFS / QPST and a Fascinate to get mine working w/ 3G. A couple things I'd be interested in documenting / learning:
1) Updating the PRL on my GS3 (or other flashed Sprint phone). I currently have to activate my Fascinate, *22891, downloading PRL w/ DFS, loading it onto the GS3, then reactivating the GS3
2) The proper procedure to get AOSP roms to work 100% (MMS in particular) on flashed Sprint phones. I haven't tried yet, but I believe AOSP roms (vs TW) require some extra work to get full functionality.

Yeah good questions, I want this to be a team effort with everyone helping and learning together......
Couple of comments on your questions..
..
1) Updating the PRL on my GS3 (or other flashed Sprint phone). I currently have to activate my Fascinate, *22891, downloading PRL w/ DFS, loading it onto the GS3, then reactivating the GS3
I am not clear on why you would need to reactivate to update PRL, What PRL are you using now?
2) The proper procedure to get AOSP roms to work 100% (MMS in particular) on flashed Sprint phones. I haven't tried yet, but I believe AOSP roms (vs TW) require some extra work to get full functionality.[/QUOTE]
This one hopefully some others can chime in as I run TW Roms myself, but this is exactly the things I want this thread to answer for ones needing help.....

#1 - Right now I'm just using the Verizon PRL that was on my Fascinate when I got the 3G keys from it - 53022. To get rid of the roaming icon, I loaded eri.xml onto my phone and changed the carrier name to Page Plus (actually I'm not sure if this actually removed the roaming triangle, but I rarely see it anymore.)
I know there has been a VZW PRL update since then - It's something like 53078 or 53096 now. I'm in the Chicago area so the exact PRL number probably depends on that.
I'd like to update the PRL on my (sprint) GS3, however the only way I know how to do it is by reactivating the Fascinate on my account to get the newest PRL, then saving it w/ DFS, then loading it onto my GS3 using DFS (then of course reactivating the GS3).
I was under the impression that *22891 to update PRL doesn't work on flashed Sprint phones, unless I"m mistaken?
***
As for #2, I did ask xda member alphahere about getting MMS working on AOSP roms, as he had mentioned in one of the PagePlus threads that he had AOSP fully working on his Sprint GS3. He gave me the following advice (which I haven't tested yet):
/system/etc/apns-conf.xml changed to the following to fix MMS
<?xml version="1.0" encoding="utf-8"?>
<apns version="7">
<apn carrier="Verizon"
mcc="310"
mnc="004"
apn="internet"
type="default,supl,mms"
mmsc="http://mms.vtext.com/servlets/mms"
/>

I believe you can do the *22890 option 2 new PRL
the problem is that when it reboots it will have a roaming unless you go into dfs/cdma and change the Preffered Settings
Sys Pref=.HomePref Pref Mode= CDMA_HDR Pref Serv =.SystemB Band Pref= Auto Roam Pref= Auto Analog=Dis
Thats is what I do
A way to tell which US Cellular S3s are unable to have keys/pass pulled?
Hi @Viper32 -
I have two quick questions:
You had written
Current Status is that I can pull keys/pass on ... Some US Cellular S3
Click to expand...
Click to collapse
. I'm looking to buy an S3 and was wondering if there was a way for me to determine if I could use your technique(s) to pull the keys/pass from a phone. Is there anything particular I can look for?
Lastly, I am wanting to flash the phone to Straight Talk and not Page Plus - do you know if I'll be able to get 3G with ST as well?
I greatly appreciate you sharing your thoughts and time here @Viper32 - huge thanks!

That is correct dirkdigles
I also believe that if your in a 4g area that it you may get a message saying " I'm sorry but we unable to program your phone at this time " when you attempt
I am in a 3g area so that might make a difference as well; since it not looking for 9900000000's to program to 4g

Some US Cellular
Does anyone know what @Viper32 is referring to when he says that only "Some US Cellular" phones are able to have pulled keys/pass?
I only have one chance at buying a phone, if it ends up being a no-go I'm out the $$$ - is there a way to know if this process will work with a particular US Cellular phone?

Well I quote that because I have only come across 2 US Cellular S3 phones, one I was able to pull keys/pass the other I was not. I would not personally run away from it if its a great deal.

Can you share your method of how to pull the aaa keys from the device?
Hello, users of I9195!
We are (users of 9195 in Russia) have a trubble with network of this model. It was found that some Samsung phones have default AQUISITION ORDER like UMTS->GSM. I.e. UMTS has higher priority than GSM. And this is a problem. Because there is not so good 3g coverage. And when you are in that area, and level of 3g goes down, we have no network signal at all. For a few seconds (tens of seconds). After that phone is again registered in the network in GSM (2g) mode. May be the problem is not in AQUISITION ORDER, but I would like to test it.
So I need to enter into servise mode (to see DEBUG SCREEN). I know that it was possible using *#0011#-back-input key 1-back. But in my firmware it is impossible.
Could you please try to enter this mode and then say if it was successfull what firmware (modem) you are using.
Great thanks!
in new firmware samsung is blocking the full servicemode
You can just manually select the mode to 2G only?
yes, I can use only GSM, but I don't want to do so. Because I constantly use mobile internet.

Now you can!
[REF][ServiceMode] How to make your Samsung perform dog tricks
i have entered the service mode after reading your guide. first of all thanks for it bcoz no other method was working.
i am getting no service message there and moreover under network lock i only have the option of sha256 info, no other option of turn it off. how i can get these options. need help.kindly reply
Hello XDA,
As many of you have been flashing custom ROMs; some of you have had an issue regarding broken mobile data/LTE/GPS has arisen. I too had this same issue when I was flashing ROMs and decided to post my fix. This is a guide that MAY fix your problem. NO GUARANTEES
For this to work properly you MUST be on a STOCK TW ROM. I used S3R.x's ROM but you can use whatever works for you. After you have gone back to a Stock TW ROM follow the steps outlined below:
1. Enter the Samsung service mode by typing this code into the dial pad *#197328640#
2. Then go to Mainmenu>UMTS>Common>NV REBUILD>NV REBUILD> (Important: don't exit the menu yet!)
3. Wait 30+ sec
4. Long press power button and select "Restart / Reboot"
5. Now check your GPS from any software that may use GPS like "Maps" or "GPS Status"
6. Flash your favorite ROM and go about your merry way!

Again this is a fix that worked for me and may not work for everyone. Also if any of this info is wrong or needs corrections, I am always open to suggestions! :highfive:
I get a connection problem or invalid MMI code error.
I can still make phone calls and sends and receive texts though.

Worked wonders on stock rom after 4.4.2 update. had lost all gps and glonass, now the reset has brought my phone back from almost being thrown out of a 3 story high window to the ground. I also reset gps from the GPS Status app as well and downloaded the Xtra data and a-gps data. locks in seconds now. Thanks so much for the assistance.

first, thanks to everyone on this forum. helped a lot in unlocking my device.
however there is no access to options. for example, at the Network/apn page, i cant add a new access point, another example is on the contacts page, i cant check contact options.
I have a bad "back" and "switch" so i downloaded button savior, works fine.
pressing either the home, back or the switch key doesnt help open the options menu.
this started after i installed zedi x20 custom rom. and i dont wish to revert back.
the device is a verizon samsung note 2 model number sgh T889 (model no changed after custom rom was installed)
also, after network unlocking, device doesn't work with a particular sim network (globacom), i.e network not registered, but works with others, any particular way around this?
finally, i am overwhelmed by all the various options regarding upgrading android firmware, since am scared of bricking, i wish to update to a higher android firmware. any suggestions for my note 2?
thank you.
