[Q] Verizon Trophy AWS or just PCS?

Does anyone know if the Verizon Trophy will do CDMA on AWS with the correct PRL on any of the available radio software?
Also is there a app or a way to show cdma call info such as channel, PN, rssi?

http://www.microsoft.com/windowsphone/en-us/buy/7/details.aspx?id=1685
It says "HSPA:AWS 2100" and that is the GSM Trophy. I think its safe to assume that the Verizon model supports it as well + CDMA.. but.. well.. AWS is new one on me. I won't pretend to fully understand what your talking about. XD *haha* I better go do some reading.

AWS is advanced wireless services. It's the FCC name for the band of spectrum the 1700 and 2100mhz range.
What I'm not really sure about is if the same radio is used for both CDMA and HSPA. The phone can do AWS if using HSPA, but it uses the cellular and PCS bands for CDMA. (800 and 1900mhz)
The issue is that the radio need to be programmed for those bands and there is hardware needed to make it happen. So a phone programmed for 800mhz can't just switch to 2100mhz unless there is hardware present.
The Verizon version of the phone might just have an extra radio thrown into the case that operates seperatly from the GSM one. If that is the case then it wouldn't be possible to use CDMA on that frequency. If it's all tied into the same radio then it seems like it could be done in software. In either case I'm not sure if will ever happen because you'd probably need to write your own firmware to do so. (It really wouldn't make sense for HTC to waste time seeing if the phone would do CDMA on 2100 if it wasn't designed to)
For reference there is a great article covering the bands here:
http://www.phonescoop.com/articles/article.php?a=99
There is also the full version of the spectrum chart online here: http://www.ntia.doc.gov/files/ntia/publications/2003-allochrt.pdf
There is a dev screen you can get to on the phone to show signal strength and a few other options. If you dial ##634# you can select field trial. You can see Channel #, band class, Active Set Pilot PN, Rx Signal Strengh, Rx Power (dbm) under the EVDO screen. There is also a section for 1x and GPS. I'm not sure if another option shows up for HSPA if the phone is on GSM...
EDIT: The best I can tell is that AWS uses UMTS/WCDMA so the phone should support that. HSPDA is just a faster version of WCDMA so since the phone can do HSPDA on 2100mhz it would be able to slow down to WCDMA speeds. The only time I could see it possibly being an issue is if CDMA was being used on 2100mhz and not UMTS.

Only thing I am seeing inside of the newest Verizon Trophy software (mango v3 8107) is that they added support for CMAS.
Code:
[HKEY_LOCAL_MACHINE\Software\Microsoft\ShortMsg\Settings]
"CmasOperatorEnabled"=dword:1
[HKEY_CURRENT_USER\Software\Microsoft\ShortMsg\Settings]
"CMASAlertOption"=dword:1
[HKEY_CURRENT_USER\Software\Microsoft\SMS\Broadcast]
"TestPort"=dword:4370
As for radio, there is only one radio software.. but from what I can tell, the CPU/radio has all the same support as the Trophy GSM, but with the added CDMA. AWS should work, but only via GSM bands.

[Q] "Unregistered Network" after 5 days of fully working Galaxy S5

Hi everyone,
I got a new Galaxy S5 (sm-900-w8) for my birthday. The device was bought in Canada.
It got unlocked for international usage (entered the 8 digits pin-code) and it worked PERFECTLY for 5 days.
After those 5 days the device got turned off because of the battery died. Recharged it and turned it on, and suddenly I get "Unregistered network" message on my lock screen.
Tried 4 different SIM cards from 4 different providers. Still, nothing.
The device DOES recognize a network when I turn it on, but after I'm trying to make a call 2 times (and gets a "call ended" message), it goes back to "Unregistered network" message or "Emergency calls only" message.
Please note that the signal bar is full.
Any idea how I can fix this problem?
Also, I rooted the device after the 3rd day. Does it mean I don't have my warranty anymore?
Thanks.

You didn't provide enough information for us to know what is going on.
The unregistered network simply means that your phone isn't detecting a valid SIM card. First try your SIM in another unlocked phone to see if the SIM card and or your account appear to be working. If not, then contact your carrier to check your account settings or replace the SIM card if necessary.
If the SIM works in another phone but not yours then we'd like to know where you bought your phone as the number one suspect would be IMEI blacklisting. If that isn't the issue, then the first thing to try for any unexplained anomalous behaviour is to wipe the system cache from recovery mode.
If the problem persists then you need to start troubleshooting which is nearly impossible without a detailed description of your situation. You didn't even tell us any basic info e.g. what carrier you are using, whether the SIM works in another phone, what S5 model, firmware, a step by step description of the changes you made to your phone, etc.

Thanks for the answer.
Now that I know which information you need:
- I tried my SIM card on a different device (Galaxy S3). It works perfectly.
- Also, as I mentioned earlier, I tried 3 additional SIM cards, all of them works perfectly on other devices, but not with my Galaxy S5.
- The device was bought from Rogers in Canada. I talked to them, they said it isn't blacklisted.
- I already tried to wipe the system cache from the recovery menu. Didn't help either.
- I wrote the model in the previous message: SM-900-W8.
- The current carrier is Golan Telecom in Israel.
- The firmware is 4.4.2 that came with the device. Didn't have the chance to update.
The step by step description you requested:
- I rooted to device.
- I unlocked it using a code that was given to me from some kind of shop in the mall (wasn't there, my gf took care of it), but it worked perfectly.
- The device worked well for 5 days, then the battery died and after I recharged it the problem started.
- If I disconnect my battery for several minutes and connects it again, the device DOES SHOW that it is connected to the network ("GOLAN T"), but if I try to call, after several seconds it disconnects and the "Emergency calls only" or the "Unregistered SIM" message appears.
- Tried reseting it to factory settings and to wipe the device's cache from the recovery menu. Didn't help.

Bingo. That is why you can never have too much information when troubleshooting.
Until proven otherwise, your problem is almost certain to be the fact that you are not using the S5 model that your carrier expects. Most Israeli carriers use the 900F model and you bought a 900W8 instead. The W8 is not intended for use in the middle east and has a different spectrum allocation than the 900F model.
Ask your carrier to spell out exactly what frequency bands they use in their network. More than likely one or more bands is missing in the W8 and that will be your problem. Other possibilities include region locking, which is Samsung trying to block you from doing exactly what you are attempting.. buying a phone in one country and using it elsewhere. You should also check the carrier blacklist (this is not the same as the IMEI blacklist).. but rather a roaming block that may be interfering because you are using the phone in a country that it wasn't intended for.
And possibly.. although unlikely, your carrier may block foreign IMEI numbers. You'd have to ask your carrier if they have any restrictions regarding handsets that customers purchase from third party sources.
There is one possible anomaly here. Your first post said that your phone worked for 5 days before failing. Was that 5 days in Canada or Israel? If Israel, that makes the last possibility more likely, although it could also be attributed to other factors.
Even though your SIM card working on a different handset tells us that there is some incompatibility between your phone and your carrier's network, you may still want to open a technical support ticket. It's possible that your carrier support department may have run into this issue before and have an expedient solution. Perhaps something as simple as needing to manually add the correct APN info.

Hey, thanks again for the answer.
The 5 days that I mentioned (when the phoned worked perfectly) were in Israel. The phone was never used in Canada, so do you think the frequency issue is still likely?
I already talked to my carrier, and tell you the truth, the carrier doesn't sell any devices (at all), so I really doubt they will block my device.
Again, they didn't even knew I changed it. They checked it out when I called them, and they said they never block any device - I did mentioned that the device was from Canada.
And again: I tried SIM cards from 4 different carriers (except for Golan Telecom, I tried Cellcom, YouPhone and Hot Mobile).
Is there any other information that you need me to provide?
Just tell me what and I'll give you the information you need.

BTW, I've checked the APN info, but it's just needed for MMS and for the 3G internet.
Tried with that configuration and without, it didn't matter.
Oh! I just remembered one more thing.
I succeeded browsing the internet VERY slowly, several times (it wasn't WIFI of course). Super-weird.

That datum confuses the issue, but yes the ostensibly missing frequency bands are still the most likely culprit. Particularly since you tried multiple known good SIM cards in your phone. Something is conflicting between your phone and your local networks. And by far the most obvious cause is the spectrum allocation. Meaning that it may work erratically (or for five days) but can fail when the system tries to use the missing band(s).
Less likely, your local carriers may be conflicting with something else in the phone. Or it could be a random hardware failure, although that is very improbable. If it was a hardware failure, I'd think more in terms of a damaged SIM slot than semiconductor failure. Troubleshooting is all about ruling out possibilities and looking for patterns. So you need to work though the list of the most obvious candidates. For a start:
- Find out what frequency bands your carrier uses. And compare that to the W8 specs (Google search: sm-g900w8 specs)
- Check the roaming /region lock blacklist i.e. /system/csc/customer.xml and confirm that your Israeli carriers are not listed in that file.
- Find out what your carrier's APN information is and confirm that your phone has the same settings.
If you don't find a solution there, you should wipe your system cache from recovery mode and do a factory data reset. And failing that even write a full stock firmware image to the phone again - the latest firmware available just to cover the slight possibility that it could be a firmware bug.
And while not a panacea, you should still open a support ticket with your carrier. Don't get them mired in a long set of I've already tried this and this and this.. Just tell them that your phone worked fine for 5 days and now gives an "unregistered network" error. And that your SIM continues to work in other handsets. That should spur them to look into your account settings and hopefully identify anything that may be conflicting with your W8 phone.
And as a last resort, I guess claim it under warranty. If you used Towel root your warranty is probably still intact. You can boot to download mode or install the Phone Info app to find out your Knox flag status. If it is 0x0, then you only need to restore the stock firmware and you should be fine with respect to warranty.
If your Knox flag is 0x1 for any reason, Samsung will raise a stink about it. A lot of carriers don't care about Knox with respect to warranties thought. I don't know Roger's position on that point but in any event don't make a warranty claim directly with Samsung if you have a 0x1 flag. Make a warranty claim through your carrier (presumably Rogers) instead.

OK, thanks!
I'll check all of those and will let you know.
Can't call my carrier on Friday here in Israel, but I'll do that on Sunday and I'll update with details.

Nope, not really all that weird. It sounds more and more like you are missing a key GSM frequency band.
Nevertheless you should check all of the possible culprits.
Good luck

Quick search using google:
According to this: http://www.worldtimezone.com/gsm.html, Golan uses 3G 2100 frequency, which is supported according to this: http://www.samsung.com/ca/support/model/SM-G900WZKABMC (tech specs are expendable at the bottom).
Other frequencies seems to be supported as well. Actually, all the frequencies of the Israeli carriers seems to be supported.

If your handset supports all active frequencies that is great news, but you still need to work through the rest of the list of things to look into. Also, if you know anyone local with an unlocked 900F S5 phone, try your SIM in their phone.
Specs for Israeli 900F and Canadian 900W8, differences in bold.
You need to confirm that your carrier does not use the missing frequencies i.e. B8 (3G GSM 900) & B20 (LTE 800)
SM-G900F
2G GSM B8 (GSM 850MHz), B10 (E-GSM 900MHz), B13 (DCS 1800MHz), B14 (PCS 1900MHz)
3G UMTS B1 (IMT 2100MHz), B2 (PCS 1900MHz), B5 (US 850MHz Cellular), B8 (GSM 900MHz)
4G LTE B1(2100), B2(1900), B3(1800), B5(850), B7(2600), B8(900), B20(800)
SM-G900W8
2G GSM B8 (GSM 850 MHz), B10 (E-GSM 900 MHz), B13 (DCS 1800 MHz), B14 (PCS 1900 MHz)
3G UMTS B1 (IMT 2100 MHz), B2 (PCS 1900 MHz), B4 (AWS), B5 (US 850 MHz Cellular)
4G LTE B1 (2100), B2 (1900), B3 (1800), B4 (AWS), B5 (850), B7 (2600), B8 (900), B17 (700)
.

OP this may sound ridiculous but go into your System>About Phone and check for your imei... you can also do *#06# hit send on your dial pad...
If your imei shows 000 or something weird other than the one that is printed on the sticker under the battery or box then you have a defective phone. I usually see this Unregister Network thing happen to quite a few Samsungs over the years, starting with the S2. You may have done something and caused the IMEI to get lost/wiped in the EFS.
The best thing to do in this case is you have to have the IMEI rewritten. This may be really easy if there is still an EFS backup on the phone or if it is still accessible. Otherwise at the time of writing this I think both the Octopus/Z3X cannot write IMEI on the S5 so taking it to repair shop can be pointless until it does.
Worse case scenario is your actual baseband chip is screwed.
Anyway, check to see if your imei is there. No IMEI = network cannot register you on as you device doesn't exist.

Meizu MX5 no 4G network capabilities

Hello,
I have been using my Meizu MX5 for about two months now without the 4G network working. I have recently updated to the latest firmware and I am currently running Flyme OS 4.5.2.7A and that has not solved any issues either.
I have checked that the phone settings are configured properly.
Network Mode is set to "4G First".
The phone is pending between, H-, H and H+ connection (3G I believe?)
I have checked with my provider and these are the following frequencies which should be providing 4G in my country (Sweden) for the provider:
800Mhz, 900MHz, 1800MHz, 2600MHz
Other providers have the same frequencies as well.
I have also gotten two new SIM-Cards during this period of time without it solving any issues. I have tried the SIM cards in some other phones and they get 4G connection without any issues.
I have been in contact with Meizu customer support in China and after some random troubleshooting of factory resetting and reinstalling the same firmware on the phone without solving anything.
They have also provided me information regarding the different bands/frequencies which the phone operates on:
GSM/GPRS/EDGE (900/1800/1900MHz)
WCDMA/HSPA+: Band 1/2/8 (900/2100MHz)
FDD LTE: Band 1/3 (1800/2100MHz)
TD-SCDMA: Band 34/39 (no freqency specified)
TD-LTE: Band 38/39/40/41 (no frequency specified)
I am not 100% sure on how this works but according to the information I am given, the phone and my provider share at least one frequency for the 4G network and therefore I do not understand why it is not working.
I am sure that it is software related and thus I won't send my phone back to China (4-8 weeks delivery time and all expenses has to be paid by me) for them to troubleshoot.
Anyone here who has knowledge which could give me an answer?
Kind regards,
Martin

Hi mate.
I had this problem but upgraded to new firmware late last night and it came on. Thankfully!
Give it a try

Hi,
I have checked the upgrade app on the phone and it says I have the latest firmware.
Which firmware version are you running?
Kind regards,
Martin

Maybe it is an APN related problem. Look if you have the same data as in the other phones that 4G works

Hi iicc,
Thank you for the reply.
I have checked the APN settings about four-five times and I can't find any inconsistencies. I have even crosschecked it with a support technician from my provider.
The only things I can think of is either my anntenna being gimped, that the firmware is not properly developed or that somehow there's trash in my system and that my phone maybe needs a complete wipe and reinstallation.
After the upgrade to firmware 4.5.2.7A the phone does not even hint on trying to connect to 4G. Pre-upgrade it atleast connected to 4G for about 5 seconds and then went down to 3G.
Kind regards,
Martin

Let me try to come up with something that might be your problem. If you are using 3 as your mobile provider then they use FDD-LTE band 7 & 20 none of which are supported by the MX5 and 3 are also using TDD-LTE band 38 which is supported by the MX5, but might not be available in your area.
If you are on Net4Mobility then they use FDD-LTE 3,7,8 & 20 of which only 3 is supported, so it could that in your area there is no coverage with band 3.
If you are on Telia, the story is pretty much the same as Net4Mobility as they use FDD-LTE 3,7 & 20.
In order to get more from your phone. You can open up google and search for 'meizifan eu' and go to the website. They have a pretty good description of how you install the international version of FlyMe on your MX5, the international version is called 4.5.2.7i. I believe it activates some other FDD-LTE and TDD-LTE bands.

1800Mhz band is a short range, higher bandwidth frequency which usually is less common and given that it has a short range it most likely isn't available in your area.

Let me try to come up with something that might be your problem. If you are using 3 as your mobile provider then they use FDD-LTE band 7 & 20 none of which are supported by the MX5 and 3 are also using TDD-LTE band 38 which is supported by the MX5, but might not be available in your area.
If you are on Net4Mobility then they use FDD-LTE 3,7,8 & 20 of which only 3 is supported, so it could that in your area there is no coverage with band 3.

Thank you for the reply nasty_suicide!
I am using Comviq Tele2 as provider, which should use the Telia net.
This is what I believe as well, but I really thought there was no way to flash the international version onto the phone and was about to abandon ship by buying a new phone yet again.
I will try to install the International version as soon as I have time to follow through the steps. I have found the guide on Meizufans.
Once I have installed the international version I'll let everyone know the outcome.
Kind regards,
Martin

Hi Hawdes,
I've exactly the same problem as you do, please post back once you instal I version. I was planning to do so but since I already have everything installed I didn't want to go through trouble for nothing.

What were the results of this? Is it true that firmware can affect the signal received?

upgraded to the latest firmware yet?

What about in Samsung galaxy s7 version of Flyme OS?? I cannot see 4G option.

[GUIDE-WIP] Unlock 3G/LTE bands your LeEco Le Max 2 & fix USA Band selection issue

[GUIDE-WIP] Unlock 3G/LTE bands your LeEco Le Max 2 & fix USA Band selection issue
When people received their X829 (without the B20 support), they realized that unlocking bands does not work in this way for this device. Some are working at the moment to figure it out. Until then, only fixing USA band selection will work. Thanks for understanding and sorry for any inconvenience caused.
Hi all,
After getting into some trouble with accidentally selecting USA Band in "Select Radio Band", I started to search for help on the forums and read a lot. Below you will find an easy way to unlock additional bands on your device or fix the issue of improper band selection.
DISCLAIMER
Given that maybe nothing will happen to your warranty or there are small chances that your device might get bricked, I feel the need to say that I am not responsible for any damage caused by following these instructions. Any modification that you do to your phone you're doing at your OWN RISK.
The steps are quite easy to follow and the instructions are made for beginners and for those who don't know ADB commands (I am one). There are plenty guides out there I should say, but this one is adapted to our Le Max2 and I need to say that it WILL FIX the USA Band selection mistake that some might do
Lets pass to the instructions:
1. Make sure your phone is rooted and you have SuperSU installed, ADB drivers installed
2. Download "Setup DFS Studio" from http://cdmatool.com or the DFS Studio 16.05.31.0 (an older version) from here https://mega.nz/#!h1ImHJyK!gBcp2j6wIp6e6smNvwuQ-GvxNTL6mYSoIjPkY_hJJVY
3. Connect the phone to the computer via USB
4. Select MTP and USB debugging
5. Open command prompt from Start => Run and type "cmd.exe". Once opened, type "adb shell". It should show "[email protected]_x2:/ $"
6. Open the SuperSU app on the phone
7. Type in cmd.exe "su" and grant access of ADB shell in SuperSU, you will see "[email protected]_x2:/ #"
8. Type in cmd.exe "setprop sys.usb.config diag,adb" and your phone will enter into Diagnotics Mode - this means that the MTP connection will be lost (you won't find any portable device in My Computer).
9. The drivers should be installed for the Diag Mode (in my case automatically - Win7 32bit) and you can see in Device Manager at Ports - Qualcomm HS-USB Android DIAG 901D (COMxx).
10. At this stage, if all should be well, you can start the "Qualcomm Tool" from DFS Studio folder. You can close the login window and it will run in demo mode (enough for what we need)
11. In the "Main" tab, double click on "Qualcomm HS-USB Android DIAG 901D (COMxx)" to select it - in the DFS log you will see "Qualcomm HS-USB Android DIAG 901D (COMxx) device in diagnostic mode"
12. In DFS Tool select tab "Band"
13. In tab "CDMA/GSM/HSPDA" select "RF BC Config" and then "Read"
14. Select the bands you need and then press "Write"
15. In the same tab, select "Bands Preffered" and do the same as above (read-write)
16. Select "LTE" tab which is aside "CDMA/GSM/HSPDA" and do the same as above. I changed values only in "LTE BC Config #6828" as the "LTE BC Config DIV #6829" didn't work for me when I pressed Read (there was nothing selected, all blank).
17. After operation had been completed, close Qualcomm Tool, unplug the phone and restart it.
Notes:
1* At point 9 if the drivers do not automatically install, search for HTC DIAG DRVIER and change the .inf file and install them manually
2* To exit the diagnose mode, just unplug the phone from the computer and it will return to normal on the next connection. Kindly note that during the diagnose mode, the phone will be in "Charge only" state.
3* To make sure that the procedure is successful, do the steps once again and press only "Read" after the restart to see that the bands are indeed added.
4* This guide might be used for any Qualcomm device as long as it can be entered in diag mode.
5* To fix USA BAND Selection issue, it is necessary to select in "Band Preferred" the same bands as in "RF BC Config" and then write them.
6* Some might think that if they will select all bands, then the phone will work also on the Moon/ Mars. Well, that's not the case... I'm not sure what antennas are within the handset itself and if it will be able to work on different bands than specified by LeEco, but one might give it a try.
Original bands of the Le Max2
2G: GSM 2/3/5/8; CDMA (BC0 / BC1)
3G: WCDMA B1/2/5/8; TD-SCDMA: B34/39; CDMA (BC0 / BC1)
4G: FDD-LTE: B1/2/3/4/5/7/8/12/17/20/25/26; TDD-LTE:38/39/40/41
FAQ:
1. Will it work on my device? A: The tool is only intended to be used on Qualcomm devices, it won't work on Exynos, Mediatek, etc...
2. My device has a Qualcomm processor, can I unlock additional bands? A: In theory yes, but the hardware matters the most. This tool is just to unlock the software side.
3. I have unlocked band 20, why doesn't it work/connect to a network? A: As stated above, this depends upon the phone's hardware and antennas. Nobody can guarantee that if you'll unlock a specific band, then the modem will connect and operate on that band. The phone needs to have all the necessary hardware in order to operate properly but to only be limited on the software side - this is why we use this tool
4. What phones have been reported working until now? A: Why don't you give it a try and write down your feedback here?!
Credits for this goes to chatmonchy who actually gave me the idea to restore the preferred bands; the various guides for a lot of Qualcomm devices that can be found over the web; XDA community.

I am wondering if this is needed for Indian variant which already supports the above list of LTE bands? In India, they are using only 3 LTE bands. B3, B5 and B40.

Well, for sure not in your case. If you travel a lot, then you might feel the need to change something. I saw over the forums that some people ask about the bands supported by the phone or some complain about not having signal on some networks, then at least they should check what is enabled in their device.
I noticed that on Indian ROM when you enter *#*#4636#*#* in dialer and you select Phone information and then Select Radio Bands, there is nothing to select. Can you confirm please? On the Chinese rom the options are "USA Band" and "Band 6". Selecting any of these will break the preferred bands in Le Max2 resulting in loss of network in Europe or somewhere else.

You are right, on Indian 15s firmware, there is nothing to select under Select Radio Bands in testing menu.

Any way to check the LTE-A/4G+ support with this method?

Thank you soo, soo much for this solution. A life-savier. Setting the band-preferred worked for my LeEco Max 2.

I tried step by step but after completing there is no extra band options in band selection I.e *#*#4636#*#*, log says nvwrite complete.

thread: [GUIDE] Unlock 3G/LTE bands in your LeEco Le Max 2 & fix USA Band selection
Hi, gyus
I had the same problem, i select USA band and everything went wrong,
The simplest way for me was:
installing "X820 LeMax2 RevolutioN_Team Resurrection Remix", no other from TeamSpain, only Resurrection Remix
http://revolutionlemax2.blogspot.al/
https://mega.nz/#!T9o0wAhJ!iLa9mrPAr5wObvygnF5giyioUnJKnVkCg3_L-q2RgnA
then after installation, go in dialer and call *#*#4636#*#*.
There are three band: Automaic, USA, and EURO.
I select the EURO and everything i'ts OK.
BEFORE DO ACTIONS DON'T FORGET TO BACKUP ALL THE ROM WHERE YOU ARE WITH TWRP

Generally shouldn't be any visible changes in there. The change you will see if you will have a network working on a different frequency than it was phone's default. Also DFS will show at next connection what bands are enabled.

Thanks, good to know. I think it would have been better to select Automatic and not Euro, despite that you may live in Europe, if you will travel outside or you will sell the phone, it might not work anywhere else except Europe. Maybe I'm wrong...

Okay, i didn't think it, you can select Automatic without problem and the band will return.
I don't know why, but in this ROM the selection band have change. Not have more Euro band and in his place are Japan and two others, but the Automatic and USA are there, no problem

This link is CM13 modified by TeamMSpain [RR] ResuRRectioN RemiX LeMax2 x820 RevolutioN_Team (the name of the ROM: RR TeaMSpaiN RevolutioN FINAL) and is good ROM, but have problem with recent button, not have RemoteControl and CallRecorder app, but you can record manually when you call and the recorder you can find in FileManager. After installation you can type in dialer *#*#4636#*#*. Click Phone Info and after in dot menu click the select radio band. There are the bands what's your needed. But the Automatic is for all us LeMax2. Don't forget to Backup the ROM where you are now.

I am in Canada using Wind Mobile. Is there any advantage if I pick USA bands? Can I switch back to prefer bands if I want to? Thanks

It's possible that you might not get any signal although I'm not sure about Canadian networks if they have anything in common with USA ones. In Europe won't work, this is for sure.
You can try selecting USA Band in the dialer. To restore you have to follow the procedure in the op.

I added the bands for Japan that I need (especially 800mhz for 3G in rural/mountain areas, and a couple of the lower frequency LTE bands my carrier uses). Although the Qualcomm tool on the computer reports them added, and I am given the option to select Japan bands on the phone, they don't seem to make any difference to my reception - they should improve reception in mountains and inside concrete buildings, but they don't whatsoever. I see no change at all and am therefore sceptical if the modem hardware is actually capable of accessing these bands even if they are turned on in the firmware.

Is there any harm in enabling every single bands? I know most of them won't work but there is no way to really tell which ones will work and which ones won't. And as long as there is no harm in enabling them all I might as well try it. Has anybody tried enabling them all?

This is why it's written in the op that the phone maybe does not have the hardware capabilities. This is like the first confirmation that it does not work, although we should see if more people claim it not functional.

I have enabled all the WCDMA bands and there is no problem with my unit. I can't guarantee for yours, but I don't believe that will happen something.

Well, was no harm in trying anyway.

It has LTE bands for Sprint, but I do not know if the Sprint store can add it to its whitelist and let it work.

Unlock Bands is already possible

I have a ta-1083 with bands b7 and b28 blocked, I've searched in several places on google and still could not find something that can release these bands,
Has anyone with this problem been able to solve this problem?
I like the device, but it's already boring with this situation
Thank you all

No way. It's not going to happen. Quit wasting your time and buy another phone that has the bands you need.

Thanks for the answer, and this is very sad to read

6.1 plus supports all the bands. You can use this code *#*#4636#*#* to change bands and it works.

Yes, it runs on 4g, but in bands like b5 and b3, but these are not standard here in Brazil, the network with the largest coverage is b7 that runs at 2600mhz,
So it fluctuates a lot between bands and often loses the signal altogether
I've changed a lot in these settings, but it doesn't solve 100%

No, you don't know what a band is. You can't use the test menu to add additional LTE bands. Kindly refrain from posting this idiocy here.

I know what is LTE Bands. 6.1 Plus supports all the bands but the fact it is configured in such a way the user can't change it hence the network switches bands automatically.
The LTE Only option configure the network to the 4G but yes you don't have the option to lock a particular frequency unlike other stock Android devices.
I dont know about other countries but here in India I use Jio 4G with 6.1 Plus my phone locks into 850Mhz , 1800Mhz & 2300Mhz (Jio supports it) simultaneously depending upon the conditions in my location.
The Android one might have disabled advanced band locking (FDD & TDD) feature. I'm not talking idiocy here.

You are not talking about the same thing. The OP of this thread wanted to unlock bands that this phone doesn't normally support. We're not talking about "band locking".

Oh yeah this doesn't supports 2600Mhz
