Hey guys,
I ran the Suckit Verizon boot unlocker exploit, and it was successful. At which point I used TW Recovery to flash Android Revolution HD 8.0 (N7100 ROM). My phone wouldn't connect to the Verizon network, saying I did not insert the proper SIM card. I found this strange, but realized Verizon locks their network to international phones. I then used the Verizon Toolkit to flash back to stock recovery and ROM. After doing so, I still had no luck in activating my phone.
I called tech support (now having stock everything) and they told me it was likely my SIM card. After spending 2 hours at the store today, it is clearly not the SIM card. They have no idea what the problem is...
When I flashed Android Revolution, I wiped my efs. Could that be the problem? Is it possible to flash a new EFS or COM3? I have no clue how to reactivate to the network..
Anyone have this problem? I did a search on both Suckit Verizon and the Verizon toolkit thread and no one appeared to suffer from this. Please help! Any solutions are greatly appreciated. Thanks in advance. Will update if those guys at Verizon come through.
Definitely has to do with wiping my EFS and not saving it. Under Settings > About > Status IMEI is unknown as well as all other carrier info.
Can someone send me their EFS or is their a way to restore the EFS without having backed it up?
Flash the full Odin restore image and that should fix the problem. Note, it will wipe your data and re-lock the bootloader, but it should at least connect to the network again.
If the stock Odin doesn't work since your imei is unknown this may be what you need, but listen to imnuts first

Flashed stock rom. No luck. Now I have to root back, as one of the prerequisites is being rooted. Will get back.
I kind of had this same problem right after I rooted/unlocked and before flashing any ROMs. I was getting signal bars but kept getting a cannot connect to network error every time I tried to place a call. I called customer service and they "reset" my account, whatever that means but it still didn't work. Started driving to the Verizon store and decided to try one last factory reset and it started working! An IT guy at my work said the account reset plus factory reset got my device sync'd with Verizon signal again. Don't know if what he said is true...don't know why it worked...don't know if this will help you but I thought I would share my experience. I know what you are going through so good luck!

I had almost the same problem using MIUI for AT&T's variant. I was able to get most functionality back by accessing the hidden menu and doing the ##RTN#, but still cannot get 4G LTE back. Maybe this will help you get started too.

According to the OP instructions - which I have done entirely correct. Put phone in Debugging, Went to Qualcomm settings in Hidden menu and set to "RMNET + DM + MODEM" , connected to the proper COM port, clicked the READ on top, however when I go to click the second read to populate the information -> Says cannot set device into DM mode.
The instructions and accompanied video do not reference having to place the device into DM mode at all. The fact that I am getting this error message is also a unique problem.
Anyone know what this could mean or how to fix it? Could it be due to the USB Qualcomm settings not "taking or shifting", although it does confirm that I changed by saying "Saved"
Also, can Verizon Wireless sync my IMEI in store if I bring the original box with the IMEI barcode on it ? Can they flash / scan it to the phone?
anybody?
Can Verizon Wireless sync my IMEI in store if I bring the original box with the IMEI barcode on it ? Can they flash / scan it to the phone?
I know with a fact that the stores do not carry any flashing software for any smartphones. So there is nothing they can do.

When I put Galaxy Note into "Download Mode" the mode says:
Product Name: SGH-I717
Custom Binary Download: Yes (1 count)
Current Binary: Custom
Underneath the green android reads "Downloading Do not turn off target!!" It stays that way for hours. When ever I go into Download mode, it ALWAYS reads the same.
Why would that happen?
Why are you in download mode? The only reason to be there is to connect your phone to a pc while running Odin, as a means to flash a rom or a recovery.
Explain please.
Odin

That's exactly why I'm there. I'm trying to flash a stock AT&T ICS rom in order to unlock my Galaxy sGH-I717. I have Padawan JB 2 now, and cannot unlock b/c it is not ICS. I have the ICS radio (I717UCMB4).
When I start the download, then open Odin or vice versa, and chose the PIT file as well as the PDA file ( ATTStockrom), the flash succeds in Odin, but the download never happens....just says Downloading...Do not turn off target.
Its been doing that for any and every Odin rom I turn to install.
Here are the settings for the phone:
Model Number: Samsung -SGH-I717
Adroid Version: 7.12
Baseband version: I717UCMB4
Kernel version: 3.0.80-g2bd6dbe, (and some more numbers)
Build Number JB 2
I have no servicemode.apk no longe, ror any of the files that should be in the phone since resetting to factory setting (reset according to instructions before installing a rom). I did a backup before hand, but that was erased as well.
I have a backup via Samsung Kies, but it says phone is unsupported, even though I upgraded, and the software did a backup to my pc before I did the factory reset.
So, now I have the dilemna of not being able to download the necessary file(s) via Odin. I do have TWRP, but I haven't been able to get any roms to restore to ATT stock. TWRP never gives me a problem.
Less than 2 months ago I unlocked my phone, on padawan, with a jb modem.
Not sure why you think only ICS can unlock.
But, since you do, here. According to bigfau's post it's 100% pure stock.

Before I did the factory reset, I'd tried to unlock my phone numerous times, to no avail. I thought maybe I needed to go backwards to the ICS version.
Nothing has worked. The service mode app is not showing, when I look into system and other folders via TWRP they are ALL empty. The only thing that shows up when I key in *#197328640# is the message "right-hard: Back.....". Looks like the service menus items are hidden. or gone.
When I was able to access the service menu and select Unit, etc. I still could not unlock my phone.
Regardless of modem, you're not going to unlock on an AOSP. When I was standing in a t-mo store switching my service, I had to restore (to padawan/stock) to get it to pop up asking me to unlock. No codes I would enter would work at all.
Do you have a foreign SIM card in it? Or are you trying to unlock it with an AT&T inside? If you're on stock (ics or JB) and have a non-AT&T sim card in there, it should pop up as soon as it boots. Stock being anything based on stock samsung (non-aosp) firmware. Blackstar, Black Jelly, Padawan (either), and the link I posted above will all have the ability to unlock.
Padawan Stock

I am running Padawan JB 2. I even purchased an unlock code from the Unlock My site. All I get is "unlock unsuccessful". I have the AT&T sim in, which is "unprovisioned mm2. It is a U.S. card, the same one that came w/my phone when I purchased it. Right now it is deactivated. I had tried putting in a T-Mo card after trying to unlock my phone via service mode. All I got was something about a subscription, and I still could not unlock my phone.
So padawan, turn phone off, put in t-mobile card, turn it on, then what?

You cannot unlock any phone with any SIM provided by the carrier that the phone is locked to.
Do what Anthony820 says, turn the phone off, place the T-Mo SIM in the phone, then turn the phone on normally. Most TW ROMS (if not all) have not been stripped of the SIMlock code.
T-Mobile Sim

Thanks guys, but I've also been doing that off and on for the past 1 1/2 months. Nothing seems to work for me.
Sadly, you may be SOL.
As you have stated that you have made multiple attempts to unlock your phone, it might now be the case that you have permanently locked the phone to AT&T, as that is what happens after 10 unsuccessful code entries.

paid for unlock does not work. I went into service mode>Main Menu >Debug Screen > Phone Control > Simulation > Network Lock > Perso Sha256 Off >, reads "Menu Not Exist, Press Back Key, Current Command is 18543.
I press Back Key, this is what is showing in Network Lock:

[3] PERSO SHA256 OFF
[4] RAT-FREE-SUPPORITNG ON
I have not misspelled anything.
Been getting that for 1 1/2 months. I even go all the way back to Debug Screen. Nothing, no unlock, no joy.

That's so sad. I really didn't know about the 10 limit. That doesn't have anything to do with the counter does it?

No, the download counter / custom binary download flag is a separate tool which Samsung uses to deny warranty claims.
Does it not prompt to unlock, or does it just fail to unlock?
Reflash a rom and modem? Possibly reset the unlock count?
Kies Reset?
As a last resort you might like to do a full reset using Kies. Put the Note into Download mode and follow the step by step instructions at Kies -> Tools -> Firmware Upgrade and Initialization. This will return your Note to full factory default settings, with the latest AT&T version JB 4.1.2.
Of course you then need to root, customize, etc. This may allow you to start fresh.
Good luck.
I could have sworn in Crixley's post on how to unlock your phone he said to install a T-mobile ICS modem if you are trying through the service menu. Might be best to use an ICS ROM too. Doesn't have to be T-mobile.

Hi,
so I have an unlocked AT&T G850A that I'm using on T-mobile. When I tried to enable the hotspot, it gave me an error "Mobile data is not available or invalid sim card'. After long research, I learned that i need to root the phone and replace a file. I searched all over the web, but couldn't find root files for the G850A.. I'm currently using PDanet to connect to the internet using a USB, but i really need to get the wifi hotspot working.
IF anyone knows any solutions please let me know.

I am in the same situation but I dont need hotspot on this phone. I remember someone telling me it cannot be done if you are on KK 4.4.4.
But once you update to Lollipop, then the Hotspot will work on T-mobile. I read someone. Maybe someone can confirm.

SM-G850A AT&T Unlock Issue
Hello,
Hope you guys are doing well. I followed the above thread and re-flashed the firmware as recommended. However when I try to enable the mobile hotspot functionality it states that I must contact att to enable hot spot functionality. My carrier is straight talk. I just wondered if they are locking the tether functionality at the sim card level? I was planning on using the hotspot with pda net. I will mention that I left the EFS partition entact since it contains me IMEI info. Not sure if I needed to wipe any other partitions before I flashed this firmware. Thank you guys for all the help.
Thanks,
Coop
How to Hack Your Samsung Galaxy Alpha SM- G850A into a Free Wireless Hotspot even it is unlocked from AT&T?
OK so freedompop is an app that lets you call, text, and get data for free. They also include a sim card, but you need to make an account and order it. Add your credit card to make account, once you get it make sure to call them and tell them you want to be on the free service, i got some special that gave sim card plus unlimited call and text with 2gb for 5 dollars. Once you make an account go ahead and go to your sim port and remove sim(easly done by taking a small flat head at 20 degree angle to push sim out, the you can use your finger to push it down or get another small flat head and grab from both sides to pull out). It will say invalid sim.....now thanks to darksavior, this is what i did and the idoneapps gt
Rooted
Step
1. Open up odin, click options and select nand erase all if you want, then click ap and select the N900PVPUDNH7_N900PSPTDNH7_N900PVPUDNH7_HOME.tar. Connect your phone in odin mode(power down, hold volume down, home button, and power button, press up to accept and your in odin mode) then hit start untill your phone reboots
2. Mine gets stuck at the samsung logo so what you do is go to recovery mode(power down, hold volume up, home, power)get to factory reset and reboot. 5 mins later it should say setting up phone for first time, this may take 5 to 10 mins.
3. Congrats, your on stock rom. Invalid sim and attempting to activate phone should pop up, you click active and it will say failed and hit exit. Power back down to odin mode
4. Click ap again and choose the CF-Auto-Root-hltespr-hltespr-smn900p.tar file, it will restart and root, when the message appears 10 seconds to restart try to go into odin mode again and choose the twrp-2.8.7.0-hlte-4.4.img(this is the verision needed to install most roms nowadays) and install twrp. Go to recovery mode, wipe, advance wipe, select delvik cache and cache, then reboot to system. Power off phone again and go into odin mode last time, and click CP button and choose the modem.bin file and reboot to system.
5. put the GTv3.1.5.apk in root of your sd or phone so you can find it. So we need to go to settings, general, security, check mark unknown sources and discheck verify apps. go on apps, samsung, my files, all, choose where you put your file,and click on it, then hit install, open, grant root access, it should say Baseband: N900PVPUBMJ4 and Bootloader: N900PVPUDNH7
6. Click sim uicc unlock, success, and should show UNLOCKED. Click the off button on hiddenmenu and it should turn on, click the IOTHIDDENMENU button on bottom of screen, TestMode Menu, UE SETTINGS AND INFO, SETTINGS, PROTOCOL, GCF, GSM/(E)GPRS/WCDMA GCF ON, success, restart phone to see At&t at bottom
7. Settings, connections, more networks, mobile networks, network mode, Gsm/umts, automatic, then access point names, plus sign, name what ever you want, apn fp.com.attz (or what ever it says in envople your sim came in) the button on the left from home button, save, and click the circle so its green.
8. Turn on your wifi and go to playstore to download the freedompop messaging phone sim app, open it up, it should read your sim and sign you in. Turn off your wifi and you should see an H+ network. Thats it your on freedompop now
9. Since this is older firmware i looked and saw developers stopped making roms for this back in 2014, so your pretty much stuck on this firmware but its not so bad your rooted. So what i did was install System app remover (ROOT) from play store and removed the annoying samsung dms service to get rid of the activation screen and anything else i didnt want on the phone.
Bonus, my 3 year old orginal samsung battery went crazy and kinda got fat. So i ordered another orginal oem note 3 battery because ive tested batterys through AccuBattery app and found out batterys lie about their mAh size orginals dont. Anyways got the new battery, used the battery repair on it, and advanced battery calibrator app, (calabrate, ok, close ad, shut down, charge to 100%) so now my freedom pop working and brand new battery
and here is link to all files from google drive https://drive.google.com/drive/folders/0B9MVYh1yVnznNzhQeWxtUTJhZnM?usp=sharing
Yes, it works. I sim unlocked my note 3 for domestic use without sprint's help. I did it two weeks ago. My phone now gets LTE gsm through freedompop's gsm sim. There's two threads in the general note 3 sprint section to read up on, but this might be the simpler one:
https://forum.xda-developers.com/note-3-sprint/general/sprint-galaxy-note-3-international-t3339789
The tutorial needs to be re-written. The goal is to be on NH7 bootloader, 4.4 rom, and MJ4 modem. Galaxy tools will unlock the sim only on 4.4 and it only needs to be done once. I installed NH7 stock rom, rooted, then installed MJ4 modem. You won't be able to use sprint roms anymore after you're done altering stuff in the hidden menu. It will have trouble getting a gsm signal. I am on a note 7 ported rom from the main note 3 section. You can try any others if you want.
Here's the corrections from the tutorial thread:
Step 1: Do NOT install the cf-auto root recovery from that thread, since its meant for lollipop, and it won't work on kk.
Step 2: You only need GT 3.1.5 apk
Step 3: You only need MJ4
Step 4: You need to be on a 4.4 rom to do this.
Step 5: You can open the hidden menu with GT. No need to open the phone app and dial to get it.
If that doesn't work, I also installed the regionlock away app and changed some other settings of the hidden menu from the other sim unlock thread. I'm not sure if that makes a difference.
Ill try this. So from what i understand. Download stock NH7 rom from sammobile, root, install gt apk, flash the mj4 modem, and follow the directions on gt apk

Sounds right. Also install twrp 2.8.7.0 recovery so you can install a rom from https://forum.xda-developers.com/galaxy-note-3
It has to be that version because newer versions have issues with roms that use aroma installers.

Fp uses the att network. Make an apn with fp.com.attz then download the fp messaging app. It should give you a notification of your phone number. If the connection is unstable, use another rom.
ok i will try again, i did all those steps without the modom. I installed the modom last and was on at&t...then i installed rom and said invalid sim xD so ill try again the right way. it should no longer say invalid sim any more at all right? and i dont need to select the gsm network or lte cmda? just once it shows at&t at bottom make the apn?

Make sure you're on the correct bootloader and modem. It shouldn't say that anymore. As i said, you can also try the other tutorial that has a bit more stuff to edit in hidden menu. Use GT to access it.
You can try the regionlock away apk.
What darklord rom are you on? Darklord roms tend to be junk compared to the new note 7 ports.
Phronesis might work but I'm on a norma note 7 port, installed with tmobile option(not sure if that helps), and mobile networks I did not touch. It was set to auto (lte/3g/2g)
Ill try the tmobile option also, it doesnt have at&t option from install
So region lockaway didnt do anything, i try click unlock from gt and it asks for a code. I did the dial and domestic unlock but it also didnt do anything
Unless....i can only use 4.4 roms
I tried "FREEDOMPOP(CDMA sprint sim LTE)" on "MM 6.0.1 Darklord Modded V5 By JCordero31 N5N7 APPS 1/22/17" with MVNOBuzbee.zip
but it did not work. MVNOBuzbee.zip might need edited but i just decided to move on.
So then...is just this rom not working with or i need be on any 4.4 rom

You are not on the correct bootloader or modem. That's why it got locked again. Also, you can't unlock on a LP rom, so you''ll get that window for a code. So let me repeat myself:
You have to be on NH7 and MJ4 and a 4.4 rom to unlock sim. you HAVE to stay on NH7 and MJ4 FOREVER in order for the sim unlock to stick. You don't have to stay on the 4.4 rom. NEVER flash a stock rom again since it will flash its own bl and modem, in your case, PH1.
You undid all your work by flashing a stock rom...
Ok i can live with that. So as long as modem and bootloader stay same...i can unlock, then flash any 4.4 rom and not have ti redo all this?
Enabling additional LTE Bands on the Galaxy S7 with U firmware (Root not required) (North American Qualcomm S7)
In this guide, I will guide you on the steps that are needed to enable additional LTE bands on your SM-G930U device and allow you to use LTE if your carrier uses an LTE band that is not supported out of the box by the U firmware. This guide may work for the Sprint, T-Mobile, AT&T, Verizon, US Cellular and Tracfone variants of the S7. For this guide, I will enable LTE band 17 for use with my local carrier here in Belize.

1. Eject your Sim card if it’s not one of the above (If you have a SIM from one of above carriers, skip this step) (UPDATE 8/6/2018, NO LONGER NEEDED TO INSERT US BASED SIM CARD IF YOU ARE ON ANDROID OREO)
2. Insert an AT&T, T-Mobile or Tracfone SIM and wait a few seconds, a pop-up like this one will appear, tap OK. Your Device will reboot after a few minutes. (UPDATE 8/6/2018, NO LONGER NEEDED TO INSERT US BASED SIM CARD IF YOU ARE ON ANDROID OREO)

5. Once rebooted, click on the app switcher, select usb settings app, tap on DM + MODEM + ADB, tap Reboot. (do not close the USB Settings app yet you will need it again)
PC STEPS
6. Once booted, connect device to PC, wait for it to install all the drivers, verify it on device manager.
7. At this point you should be disconnected from your internet connection. MUST DISCONNECT!
8. Fire up DFS Tools folder on your desktop, double click on Qualcomm Tool
9. It will ask for login but ignore it, select your Samsung Mobile USB Serial port to connect DFS to your device.
10. Click Band Tab>LTE tab>click read, click read again.
11. Check your LTE band you want to enable (do note that some of these bands may not work. For this guide, I will be enabling LTE band 17 (700).
12. Click on write, click yes/ok on warning diag, wait for timer to go down and it writes the changes to your device.
13. Reboot your S7, connect it again to DFS and verify band was written successfully to the NV by going back to the LTE tab and clicking “read”.
14. If the band you enabled stays checked, disconnect your device at this point from PC, if the check goes away, it may mean that band is not supported in the U firmware.
15. Dial *#0011# and verify your device is connected to LTE. See below images:
17. Switch to the USB settings app, select MTP, Tap reboot. Once booted again you can now close it.

I did it, does enabling some of them cause more battery drain? and I've seen posts where people say it could cause hardware problems is that true?

It maybe can cause issues, for me i just enabled one extra band which is band 17. I didn't enable anything else because i don't really need them. My battery seems the same to be honest.

Enabling additional LTE Bands on the Galaxy S7 with U firmware (Root not required) (North American Qualcomm S7)
In this guide, I will guide you on the steps that are needed to enable additional LTE bands on your SM-G930U device and allow you to use LTE if your carrier uses an LTE band that is not supported out of the box by the U firmware. This guide may work for the Sprint, T-Mobile, AT&T, Verizon, US Cellular and Tracfone variants of the S7. For this guide, I will enable LTE band 17 for use with my local carrier here in Belize.
Ready? Cool!
Disclaimers:
I am not responsible for any bricked devices
Even though this process does not void or trip Knox warranty, you can never be too sure of what can happen, these steps have been done multiple times by me and have not experienced any issues at all.
Follow this guide at your own risk.
Things you will need:
1. Windows PC (Windows Vista, Windows 7/8/10)
2. USB Data Cable
3. USB 2.0 Port (have not tried on a USB 3.0 Port)
4. Samsung USB Drivers
5. Install (disconnect your PC from Internet once installed) CDMA Tool
6. USA Sim Card (Can be from AT&T, T-Mobile, or Tracfone, have not tried with Verizon or Sprint SIMs)
Procedures:
1. Eject your Sim card if it’s not one of the above (If you have a SIM from one of above carriers, skip this step)
2. Insert an AT&T, T-Mobile or Tracfone SIM and wait a few seconds, a pop-up like this one will appear, tap OK. Your Device will reboot after a few minutes.

You'd need to go flash the G930P PL6 firmware and then flash the universal PL2.

Flashing u firmware allows the userof any sim card flash u firmware through Odin and place the sim card desired to use, and it will give a confirmation to restart the device. It will then load into the recovery and setup the sim automatically, WiFi calling features are enabled also
