It's been awhile since I was on the forum but thought I would create a quick post for those who wish to enable LTE on the Samsung Galaxy Note 3 (model: SM-N900W8) where LTE has been crippled. I have compiled the following steps and this should get you up and running without having to ROOT your device, install RECOVERY software or FLASH a new modem.
1) Obtain the device IMEI by pressing *#06# on your dial pad and record this number to reference later.
2) Type in *#272*[IMEI Number]# Where [IMEI Number] is the number you recorded in the step above.
3) You will be prompted with a 3 letter "Regional Settings" menu. Cross reference the 3 letter code with the carrier list at the following link: http://www.samsungis.com/Firmwares/SM-N900W8.html. You do so by hovering over the 3 letter code under the "Region" column. If the SIM you wish to use is from one of these carriers and the carrier supports LTE, we're on our way! The above steps are confirmation, do not modify anything yet!
4) Unlock your device using a preferred unlocking method. Myself, I use http://www.cellunlocker.net which charges $32.99 US for a Samsung Galaxy Note 3 unlock code. It's a reliable site with quick turn-around.
5) Once you receive your unlock code, put in the SIM from the carrier you wish to use and enter the unlock code when prompted.
6) Once unlocked, it may reboot and when at the main menu, follow step 2 and 3 above but this time, select your 3 letter carrier code for the carrier SIM you just inserted then click on OK or INSTALL.
The device will go through a boot up sequence but once complete, you will have LTE enabled. If you do not see this, go into your network settings and you should have the option to select GSM/WCDMA/LTE (auto connect).
Hope this helps those of you wishing to enable the crippled LTE band but do not wish to delve into all the technical jargon related to ROOTING, RECOVERY and FLASHING.
Thanks for this.
Thanks
Thank you for sharing this wonderful trick. I was looking for something like this for a long time.
Please be noted that the secret code *#272*[IMEI Number]# does not exist in many recent models.
You can use Phone INFO ★Samsung★ app > Menu > 'Secret Codes' to check if this code does exist.
THIS WILL ERASE YOUR PHONE...
But it works...
Hello everyone,
I have a Samsung SGH- T839 Sidekick, Android 2.2 Froyo OS stuck on T -Mobile USA, I am trying to unlock. I followed the instructions in this forum: " http://forum.xda-developers.com/showthread.php?t=1110263 " .
I think I have managed to unlock since I managed to get the unlocking code in question and to inform . Besides, the message " Network Unlock Successful" appeared on my screen, more and inserting the code " * # 7465625 # ( View Phone Lock Status) " , the " Network Lock" is off.
My problem is that my phone still does not recognize my SIM card ( that of a Méditel Moroccan operator ) and by going to: Settings- > Wireless and network- > Mobile Network , I still have a window under the name "Insert SIM CARD " with the following message : "Insert SIM card to access network services ." Knowing that at any moment I was prompted to enter my PIN.
What to do? Could you help me please ?
Thanking you in advance,
Samsung Sidekick SGH-T839 Unlocking problem
Any suggestions please?
You might be able to request a SIM unlock code from T-Mobile; see http://www.t-mobile.com/Company/CompanyInfo.aspx?tp=Abt_Tab_CompanySimUnlockPolicy. Or maybe try one of the many SIM unlock services available on the Internet; just be careful, because some of them are scams.
I don't understand
Hello,
I don't understant why I should find a new code if, like I said, The Network Lock Status is off?
( " * # 7465625 # ( View Phone Lock Status) " , the " Network Lock" is off. )
Have you ever lose your phone ‘s signal due to accidentally selecting USA BAND in *#*#4636#*#* menu? If yes, this guide is for you. Thanks to @ian.anindya for guidance and clues on how to restore my phone’s signal back.
Requirement:
1. Rooted HTC One E8 phone
2. Knowledge on how to use ADB command
3. Software Qpst, Qxdm and Mztool
4. A cup of coffee
This is how to do it:
1. Download all necessary software here and extract to separate folder.
2. Install Qpst and Qxdm.
3. Enable USB debugging on your phone and connect it to PC. Verify with command
Code:
adb devices
It must show your device ID and must not be offline.
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
4. Input command below to activate diagnostic mode
Code:
adb shell
su
If this is the first time you issue the command, check your phone. There is a prompt asking for root permission, grant it. Continue with below command
Code:
echo 1 > /sys/devices/virtual/android_usb/android0/f_diag/on
5. Your PC will detect new hardware and install necessary drivers. If you do not have the drivers, browse to HTC Diag folder which you download together with qpst and qxdm software. If the drivers installation succeed, check your PC device manager and it will show your HTC Diagnostic Interface (in my case COM5, the value can be different on your PC).
Your phone is now ready for the fun part playing with NV items
6. Open QPST configuration from your windows start menu. Go to Ports tab, and then add your HTC Diag com port.
7. We need to backup current NV items in case something goes wrong. Choose start client, software download. On backup tab, select where to store .qcn file and click start and wait until finished. After finished, close QPST program.
8. Open QXDM professional from your windows start menu. Select NV Browser in the drop down list. Since we do not connect our phone yet, the NV list is not editable.
9. Choose option, communications. Select HTC Diag com port in the target port. If succeed now the NV browser window is editable.
Tick Dual SIM if your phone is dual SIM version. Subscription ID field will be activated.
ID 0 is for SIM 1 and ID 1 is for SIM 2.
For this purpose, we will only need to edit NV item 1877, 441, 946 and 2954.
10. SIM 1
Make sure Dual SIM is ticked and Subscription id is 0.
We use Mztool application to define frequency parameters.
Go to Band Preference (NV Value) tab to configure GSM and WCDMA frequency that we want to put in our phone. Choose the frequency that supported by your phone.
Mine is like this
According to the picture,
Box No.1 refers to NV item 1877. Value is 73925504 (remove commas)
Box No.2 refers to NV item 441. Value is 896
Box No.3 refers to NV item 946. Value is 1128
Box No.4 referes to NV item 2954. Value is 0
All values are in Decimal
Now we need to input these values in NV browser window in Qxdm.
NV Item 1877
On column ID, find item 1877. Click Read to read current value. Take note of it, in case something goes wrong. Write the new value 73925504 under input field and click Write. Click Read again to verify.
NV Item 441
On column ID, find item 441. Click Read to read current value. Take note of it, in case something goes wrong. Write the new value 896 under input field. The value is automatically converted in to Hex.
In my case 896 in decimal is the same as 0x380 in Hex. Click Write. Click Read again to verify.
Do not touch the nam value.
NV Item 946
On column ID, find item 946. Click Read to read current value. Take note of it, in case something goes wrong. Write the new value 1128 under input field. The value is automatically converted in to Hex.
In my case 1128 in decimal is the same as 0x468 in Hex. Click Write. Click Read again to verify.
Do not touch the nam value.
NV Item 2954
On column ID, find item 2954. Click Read to read current value. Take note of it, in case something goes wrong. Write the new value 0 under input field and click Write. Click Read again to verify.
Do not touch the nam value.
Up to here, if you reboot your phone, It should get GSM/WCDMA signal on SIM 1 only. Now we are working for SIM 2.
11. SIM 2
Dual SIM is still ticked but this time choose Subscription ID 1
Remember that SIM 2 supports only GSM (no WCDMA). So in Mztool, choose only GSM signal.
Mine is like this
According to the picture,
NV item 1877 value is 2622336
NV item 441 value is 896
NV item 946 value is 40
NV item 2954 value is 0
All values are in Decimal
Do the same procedures as SIM 1.
12. After finished editing NV items, close Qxdm and then we have to close the diagnostic mode.
Wait around 10 seconds and then input command below to deactivate diagnostic mode
Code:
adb shell
su
echo 0 > /sys/devices/virtual/android_usb/android0/f_diag/on
13. Reboot your phone using ADB command
Code:
adb reboot
After rebooting your phone, wait for 1 or 2 minutes and then hopefully you will get the GSM/WCDMA signal.
Later on, I will continue this guide on how to add LTE Band

hi there,
thanks a lot for putting up these recovery steps..they were really helpful..but only one thing is that i'm still unable to get a signal while roaming..
do you have any solution for the same..or atleast if i can get a backup of qcn file from stock untouched htc e8 ...that should help..

I have not tried roam with other network, but have you checked frequency band of your destination network? and compare with the one in your NV items list?

Hi, this is more about a national roaming within india and i dont think the bands will vary in such case...and to be more clear i had searched the bands listed for E8 dual sim on htc site and added them on the mz tool. i believe there is some other nv item that needs an edit to enable the roaming, would be of great help if you could suggest reg it.
Install Superuser "The su binary is out of date."

I am having difficulty in rooting my phone (HTC One E8 Dual Sim) completely, as I get error message "The Superuser binary (su) must be updated. Please choose an installation method. Recovery mode installation is recommended for HTC devices." Options are --> Cancel/ Recovery Install. When I choose Recovery Install, I get another screen which states "There was an error installing Superuser. Please send a log of the error to the developer."
I used TWRP 2.8.7.0 to flash recovery through ADB and installed superuser.zip obtained from clockworkmod site which I guess is the latest version of SU.
I request for your technical expertise to help m e out as I need to perform lot of troubleshooting steps further to rectify the issue with USA Band.
Thank you.

For people under warranty !
Hey Guys ! I had the same problem in my HTC E8. Gave it to the service centre and got the motherboard replaced after ~25 days.
Just got the phone back . Has a different IMEI number now.
Phone now has Wifi signal issues ( Getting very less signal strength in relative comparison to my other phone ) and it takes about ~15minutes for the data to turn ON.
Hence the phone is back to the service centre .
can be refurbished device

The warranty replacement can be refurbished ones. This is the only reason I did not send my mobile to HTC US warranty claim centre. The Indian purchased mobile also have global warranty , but the claim device can be refurbished. I purchased mine just 3 month back for full price and dont want to receive refubished unit
So still working on my second sim slot, hopefully if the first sim slot works in India once I reach , I will be very happy . Atleast i dont have to fight with HTC for warranty replacement .
Anyways i will never buy another HTC .

From an upgrade he stopped receiving GPRS signal both slots in my Xiaomi mi4i.
I've tried everything, factory reset, load roms from TWRP recovery from ADB sideload and from FlashBoot. ROMs development, global and weekly roms, and happens all the same, impossible to receive GPRS, GSM and WCDMA signal.
- No coverage icon appears on the card itself detects the mobile operator, but if you go to Settings / SIM card is deactivated status for the two and there is no option to activate.
- If you go to call tells you the radio is off and take away the airplane mode.
- The IMEI SIM cards is not lost, if frame ma * # 06 # IMEI appears both SIMs slots.
- If I go to Settings / About the phone / state in state service said Radio off / turn and Cellular Network Data desconnected state.
- If I go to Settings / About the phone and pulse several times on Kernel version, entered the Test Hardware, skewer in "3. SIM card" and the only information provided it is that it detects the SIMs but the test result is Fail.
- If I go to Settings / About the phone and pulse several times on internal memory from this menu you access to information from the SIM cards (Phone information). That I can see:
- Phone number:
- Current network: off
- GSM service: Radio Off
- GPRS service: disconnected
- Network type: unknown
- There are few buttons turn on radio, select the type of network does not work etc but the option to enable it.
If anyone knows how to fix appreciate it.
