NO 4G/LTE - Baseband Needed (kenzo) - Xiaomi Redmi Note 3 Questions & Answers

NO 4G/LTE - Baseband Needed (kenzo) - Xiaomi Redmi Note 3 Questions & Answers

Hello everyone!!
I received my Redmi Note 3 Pro last week. Yesterday, I received Xiaomi message saying I had been allowed to unlock bootloader. I did it, I flashed TWEP and SuperSU.
I was trying to unlock the 800mhz LTE band, although I had LTE with the other banbds, with the tools QPST and QXDM. First of all, I did a backup with QPST, in software download. In QXDM, I edited 06828 line, following this tutorial (http://forum.xda-developers.com/redmi-note/general/unlock-lte-bands-step-step-xiaomi-mi-t3084774), and transforming my original number to make it has LTE 20 band, with an app of Play Store.
What I got is no LTE, when I put the original code, after reboot, it kept without LTE. I flashed miui.eu ROM, later Resurrection Remix and today, fastboot ROM V7.3.2 official with MiFlash, and there is no LTE anymore, except in RR, in which changing the mode from settings, it catched LTE (but no WiFi).
Therefore, I think I need the originao baseband to flash it trhough TWRP or whatever, to make the phone has LTE as it had.
Thanks!!
Regards!!

Showing.
-8976_GEN_PACK-1.54366.1.54508.1
With 2 SIMS, no LTE on any of them. With SIM2 LTE. With SIM1 no LTE.
I also tried this: http://forum.xda-developers.com/showpost.php?p=66889532&postcount=13 But not results at all. After putting another time SIM1, SIM2 gets LTE, but SIM1 doesn´t.
Thanks!!

Hi everyone!!
I finally managed to fix it!!

I´m having problems with the ADB drivers. I have tried to reinstall ADB drivers trhough 15 second xda tool, MiFlash, MiPCSuite, MiPhone, updating "Android phone" in Device manager, with 3 warning symbols... Here it´s what it shows me while I try to open adb shell:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",

Any idea?

I re-tryed, but I got the same results, no LTE, just HSPA+.
Maybe some of you could try and maybe you get better results...

Dont give up miguel! Are you sure your carrier has active band 20 in your area? I've unlocked extra bands and what I've found is with our note 3SD's we cant check the frequency that our phones are actually using to determine what band we have in our environments. The reading of the incoming frequency(number) isn't built into the software. There is that small disconnect between our roms and the hardware. Unlocking extra LTE bands work. I unlocked all possible extra LTE bands. The problem is I cant tell what bands the carrier I use is using by looking at my phone to see what band its connected on.
The best way to see if band 20 is working is use another phone that doesn't have the hardware to software disconnect. See if the device connected to lte band 20 and if you have connectivity. Then on the note 3 only enable band 20 LTE on line 6828 of sim0. I'm not sure what the value is for only band 20 LTE. Maybe someone can post it.
After you restart the phone, switch the sim to slot 2, go to cellular networks in settings and connect manually to your 4g network. After it connects and before it gets data, pop sim out while phone is on and put the card in sim0 slot. let it load for a few min, and if you don't see anything after like 3 min go to cellular networks and see if you can select the local 4g network that you know works and on band 20. If it cant see the network or doesn't automatically connect then band 20 wont make it past the phone bandpass filter.
A bandpass filter is the only thing that stands between us and being able to receive all frequency of signal: https://www.google.com/search?q=bandpass+filter&ie=utf-8&oe=utf-8
If the filter is infact the reason our unlocking full bands doesn't work then I need someone to link a bandpass filter from ebay that will allow the extra lte bands and write a short tutorial on how to solder in the new filter.
I think unlocking bands the way the hardware currently is already works. I'm not in a location to be able to test my successful lte bands unlock until next month when I'll be on AT&T.
Good luck and please PM me any new information on nv memory hacking on redmi note 3's. I am very interested.

Any progress? I can't test Band 20 because my provider doesn't support it.

check link in first topic above, there is manual how to unlock B20 band and in step 2 use that commands instead dialers code (you see nothing on phone, just your phone opens port in device manager in PC). I have tried unlock B20 but without success and now I dont have any LTE
I am on AOSP 5.1.1

when the phone is booted up go to developer options, turn on usb debugging. Go to notification bar, turn off MTP mode. The phone should say, connected as installer. Then you go to your adb folder and open a command prompt and put in the three commands, one at a time.

i tried what you have posted, but still nothing happens, no ports tab on the device manager
i found the error, i typed usbconfig instead of usb.config
done editing,, is there an app where i can see if the bands are added??
or just by enabling the data to check for lte?
although i think it worked.. before no reception on some part of our house
now i got signal on those areas.
i researched all the lte band provided by the network(both sims)
i come from
11110000000000000000000000000000011011111
to
11111010000000001000100000000000011011111

Sorry for late reply friend. I first tried to just enable the LTE 20 band, disbaling the rest, but no result, I would try that hardware hack, but I will have to change to MIUI 7 once a time more.
I will give u more news soon!!!

Try CM13 build from @banmeifyouwant
I have fully working LTE/4G now 100% of time in Vodafone, UK. Before on MIUI... Only in some parts of Manchester, about 10%, now, perfect

QPST Help

First off, thanks for tolerating this somewhat noobish post, but I've searched through almost the whole internet trying to find answers.
Alright, so here's the dealio.
Sprint Galaxy Note 3. UICC unlocked via idoneapp, then used on domestic T-Mobile through GCF settings. I want to enable more bands as described in the following links: here and here.
I get as far as Step 9 in the second link. Then, I go to select a port, and it's not there. OK, so I uncheck the "diagnostic port only" check box, and select COM12 which is what my phone is on. No big deal, right? So I go to read/backup my NV and I start it; it only gets to 12% and says "Could not Communicate in Diagnostic Mode"
That's it. I've tried different USB ports, different USB cables, other USB modes on the phone, I even have a custom kernel. I really hope it's something obvious that I'm doing wrong instead of something that's a niche error.
Thanks, guys.

I ended up being able to read the LTE bands with DFS and write them with QXDM. The only thing is that there is no LTE/GSM/UMTS mode on the phone, so it's either LTE/CDMA or GSM/UMTS for now until I figure out if I can flash some other ROM to it to let it use the other bands, cause right now it only wants to look at band 25.

So I've been trying to flash the N900T MI7 modem/baseband on my N900P but I can never get it to flash in Odin. I've been able to put the modem and non-hlos in flash able zips and flash those but it never shows up. I've also tried to dd the files directly but that doesn't work either. Ideas?

I am impressed it's not bricked yet.

So basically what happened was I found a couple other tools to do what I wanted. First was DFS tool. This works well, because it can both read and write bands to the nv of the phone. I forget what the second was, but it could both read and write the raw value of any given value in the nvram. I'll have to dig through my stuff again if you want to know what the second program was. The fact of the matter is that I was never able to get it working right. The phone always looked at band 25 LTE no matter what bands I turned on/off of the phone.

another ?

hi
how did you connect QPST to your phone? i can't do it,
installed QPST under windows 7, QDXM and kies, but in QPST configuration i get "No Phone" when added new port

I never did get QPST to connect to my phone. I think I was able to get it to see the phone at some point, but it would never read anything from it or write anything to it. The program always froze up or something when I tried that. If I could remember the second program I used, I'd share it with you all, but for the life of me, I can't think of it.
Edit: Oh hey, the two programs I used are RIGHT IN MY SECOND POST. lol. Yeah, use DFS tool to read the NV and QXDM to write the NV. It'll save you a whole lot of trouble over doing stuff with QPST.

3G work fine but not 4G, i will install custom Rom and see if it will work.

Well, 3G will work fine without changing anything anyway. All of the bands are already enabled. 4G is the issue.

i tried to find SPC /MSL code but no chance
I will install SPR-N900PVPUBMJ4 rom and after SPR-N900PVPUBMJ3 modem and use DSF tools to set it 000000
hope i will work

Flash the MI3 (that's emm eye three) modem and then use the app included in the zip file to find the MSL code. Here's a link to the zip file: http://bit.ly/1oZDO9t
I was not aware that you could change the MSL code with DFS tools. At least I have a Verizon Note 3 now, so I have a lot more LTE bands than the Sprint version does (although I don't care all that much; I think I may switch to the Nexus 6 soon). But yeah, try the stuff in the zip file from the link, and you should be able to
Find your MSL code
Unlock your phone internationally
Use hidden menus
Most of all, have fun! I know for sure this can be very very frustrating a lot of the time, but if you don't have fun, then I don't think there's much profit in trying stuff like this. Good luck!

After many try, finaly i get my MSL code (24 hours).
I have downgrad my phone to 4.4.2, and install custom rom Galaxy-Note-fre3-2.26,
and after using adb and logcat i got my code.
Now how can i activate it for internationally ? i have added all LTE band (3,7,20) but still H+
I will try with QXDM, but i have windows 10 and give me error acces denied.

I just did it with my Verizon Note 3 on Windows 10, so I know it's not a Windows 10 issue. Also, QPST seemed to work with my Verizon phone but not my Sprint phone. Weird. Make sure you're running QXDM as administrator. Also, I unlocked all of the LTE bands in this way but I can't seem to get LTE from my GSM sim card, even by going into the service mode and enabling all LTE bands.

Yes; for LTE i found in hiddn menu, that they use Tri Bands (25, 26 & 41), so for others bands will not work.
I don't know how i can disable this and force it to use bands 3, 7 20.

I honestly couldn't tell you, and I'm not sure how much help I'm going to be in general. I've tried it on both of my Note 3 phones but have had no confirmed success. Sprint especially is the one carrier that sticks out like a sore thumb, and by association, so do their phones. I've had plenty of frustration on that front, that's for sure.

Just one question if have any idea for it
can i install Firmware N9005 using PIT file for N90005 in N900P?
Because when i received my phone(from china) , the first time i see that BaseBand version is for n9005 and phone name n900 but in download mode i see n900p
i think chines have a method to do it

Maybe. Really they have a method to do anything I would advise against trying to do that, although I'm not sure what harm it could do if you can still get back into download mode. I've tried flashing different versions' firmware to the N900P with no success.

4G / LTE connectivity on SIM1

Hello,
Are there any users with Redmi note 3 Pro / Snapdragon version that have issues like no 4G or LTE connectivity while using sim1?
this has worked for me when I first bought the phone.
I unlocked the bootloader - unofficial version, installed twrp, tried to flash a rom, bricked my deice, than I managed to flash 7.2.3 global stable official rom - my bootloader was relocked, but sim1 could no more connect on 4g network.
while searching for it manually I can see it, but when i click it to connect, it just registers on 3g network.
since than I have tried to reset the device, full erase, no luck.
I installed global developer rom - with locked bootloader - no luck
I received a code to unlock bootloader, i Unlocked it, but still no 4g connection on sim1.
Any idea what could be wrong?
P.S.
If I put the same SIM in slot 2, 4g connects with no issues, but I want to use that slot for the Microsd card.

And I kind of found the culprit.
The phone that is sold in many countries comes with customized miui 7.1.9.0.0 (note the extra 0) and on this rom version 4g works on sim 1, on global versions it does not.
And now I am searching for a customized rom that can't be found anywhere.

Well I had the same version 7.1.9.0.0 (the unofficial multilanguage) when I got the phone, but I have not activated the 4G on my providers. In the mean time this rom had many issues (didn't recognise the second sim etc) so I flashed with EDL and MiFlash the original Global rom (7.1.7.0) and was ΟΤΑ updated to 7.1.8.0 . Since then I have no 4g on SIM1 but it works fine in slot2
I then got permission to unlock bootloader and unlocked it by flashing the official Chinese Dev 6.3.31.
Someone on the official site reported that the baseband of the AOSP and/or 7.1.7.0 solves the problem if you flash it manually via fastboot... I tried all the following basebands but no luck either.
- AOSP rom baseband (A.2.0.c1.1-00005-8976_GEN-PACK-1)
- Stable 7.1.7.0 rom baseband (A.2.0.c1.1-00019-8976_GEN-PACK-1)
- Stable 7.2.2.0 / 7.2.3.0 rom baseband (1-00019-8976_GEN_PAC K-1.49420.2 .)
Now I have the Greek Stable 7.2.2.0 (based in the Chinese Stable and made by the official fan site in Greece Xiaomi-Hellas) and yet no 4G.
It has been reported as a bug on the official site and as they say the developers are looking to solve it within the next updates..

Hi Project_P we meet again! heh
OP: if you don't need dual sim, try adding a dummy sim on slot 1 and turn it off and keep your normal sim in slot 2. That fixed the issue for me (obviously not ideal if you need dual sim OR if you need to expand storage).

That is the trick, I want to be able to use the microsd slot also. I am thinking of stripping a sim card and glue it to a microsd card as per the many tutorials out there.

Have you tried changing the cellular network type to "LTE" or similar?
I managed to regain 4g by doing this

I have tried to select it manually, but as soon as i click it, it just connects to 3g network.

There are many people who have this issue on en.miui.com/ thread-265011-1-1.html (correct the link) including me.
I came from a modified ROM 7.1.99.99 by the seller and I flash Miui (7.1.8.0) without unlocking the boatloader. Result: No LTE.
I flash the 6.3.31 the same way. No LTE too.
I set preferred network type to LTE only and no signal.
I've 4g on SIM2 when I've two SIM cards and sometimes on SIM 1. It's not stable

Hello,
I am French and I also got my phone with the Rom 7.1.9.0.(0) and I also lost 4G on slot 1. Sometimes I can have it on slot 2 by putting a second SIM card slot 2, but it is very unstable and sometimes I lose it also on slot 2. I installed all the Rom that exists but the Chinese / English, but nothing has changed . Even forcing the preferred 4G, I stay in H / H +. It's hopeless, now I think selling it but I will lose money because the 4G does not work.

Up ! We need some help here

Hello,
Are there any users with Redmi note 3 Pro / Snapdragon version that have issues like no 4G or LTE connectivity while using sim1?
this has worked for me when I first bought the phone.
I unlocked the bootloader - unofficial version, installed twrp, tried to flash a rom, bricked my deice, than I managed to flash 7.2.3 global stable official rom - my bootloader was relocked, but sim1 could no more connect on 4g network.
while searching for it manually I can see it, but when i click it to connect, it just registers on 3g network.
since than I have tried to reset the device, full erase, no luck.
I installed global developer rom - with locked bootloader - no luck
I received a code to unlock bootloader, i Unlocked it, but still no 4g connection on sim1.
Any idea what could be wrong?
P.S.
If I put the same SIM in slot 2, 4g connects with no issues, but I want to use that slot for the Microsd card.

Same problems here. Have to try changing to SIM2 slot and will report back. Weird bug.
edit: Better late than never. SIM2 only supports Nano from what I can tell. Couldn't switch since I'm on Micro. Will have to try with another SIM.

Same issue here. I lost 4g in sim slot 1 somewhere along the way through changing MIUI roms (Official/Dev/China etc) trying to unlock officially.
Until today with SIM1 slot Active, and SD Card inserted - No 4g anywhere.
Today I tried the hardware mod (sticking SIM to SD Card) - I now have 4G!

This is a method to get 4g working on SIM1 for a while. I got this info from XIaomi forums:
1. Turn off your phone
2. Put two simcard (micro & nano) that support 4G
3. Set data/internet to simcard 2
4. Eject your simcard tray without power off
5. Remove simcard 1 and put only simcard 2
6. Set LTE only on simcard 1 (using *#*#4636#*#* method)(dial that number, click phone information 1 and "Set preferred network type:" to LTE only)
7. Eject your simcard tray, and put simcard 1 again
8. Wait a few minute, if simcard 2 change to H+/3G
9. Switch data/internet to simcard 1
10. And ...... 4G/LTE work again using simcard 1.
11. After this you can eject the tray again without turning the phone off and swap SIM2 with microsd card.

I have the exact same situation as OP, even living in the same country. The thing is other users on the phone's softpedia section don't have this issue after flashing the 7.2.5.
I was hoping the 7.3.2. OTA would resolve this but there's no change.
My bug report was closed saying an update will come: http://en.miui.com/thread-280981-1-1.html.
Edit: I don't have a 2nd SIM to try that, nano-SIM too.

Whenever you can do the truck, do it. I also got the update to 7.3.2.0, but it is now back on 3g. I will do the mod again now.

A few have reported that a factory reset solved some issues.

I have the same issue with my handset too. even after update to 7.3.
Today I tested with only nano sim in slot 2 & it started finding 4G signals.
But slot 1 still work only for 2G & 3G

Hello,
I will repeat myself once, but I can confirm that if you received your phone with the Rom 7.1.9.0.0 dealer, it is because of her that we lost 4G on slot 1.
I really tried everything, even change the line build.prop but nothing has changed, still no 4G on slot 1.
Maybe if Xiaomi is an update of the Baseband, we can recover but this is not certain.

I know that, but still, it should work normal with international rom, because it uses the same modem as all redmi note 3 snapdragons out there.

Basically, Redmi Note 3 comes in 3 versions, two Chinese ones (One with MTK and one with SD650) and Global one(SD650). The Global version is the one that is sold in India, Taiwan, Singapore and part of Europe. The Chinese SD650 version, mostly sold in China, says it supports more bands than the Global one.
Chinese SD650 version LTE bands:
B1/B2/B3/B4/B5/B7/B8
B38/B39/B40/B41(2555-2655MHz)
Global Sd650 version LTE bands:
B1/B3/B5/B7/B8
B38/B39/B40/B41(2555-2655MHz）
I bought the Chinese one as I need to have Band 4 to work with my USA carrier. It worked when i was in China, but same unfortunate thing happens the me when I came back to the States and wiped my phone to dev. I can't access 4g band 4 on Sim 1, 3g connection is bad on Sim1 too. Sim 2 works fine for two days and then the 4g downgrades to 3g and then 3g connection is on and off.

[GUIDE] Band unlocking for OP2

After reading through the OPO thread and someone confirming they saw bands unlocked for their OP2, but could not test if they are working as well as reading through the OP3 and similar threads with our processor I finally delved into trying this. Here is the quick guide of how to do it. Sorry if there is any confusion I will try my best to make it concise as possible. This is my first time writing a guide up for XDA.
I have not been able to test each band to confirm it's working, but it is showing up in Network Guru. I am on AT&T so I only unlocked AT&T bands (bc that's all I care about currently and it makes it easier for me to test)
I WILL NOT BE HELD RESPONSIBLE IF SOMETHING WRONG HAPPENS TO YOUR DEVICE BY FOLLOWING THIS GUIDE!
Credit: All my fellow XDA'rs who have been diligently testing, experimenting, bricking/unbricking, creating ROMs, FLASH, Root ability, and Bootloader unlocking. You are the heart and soul of XDA!

[URL="https://forum.xda-developers.com/member.php?u=7846474" @baskaflyfer[/URL] Rmt Storage Patch Zip
Here is the OP3 thread I based this guide off of and credit to all those mentioned in there as getting this far would have been impossible without them: https://forum.xda-developers.com/oneplus-3/how-to/guide-unlock-additional-lte-bands-t3519563
OKAY:
PreReq's:
1. Rooted
2. TWRP or like
3. RMT Storage patch from OP3 forums: SEE POST BELOW!
4. DFS Explorer - Find via searching XDA, again checking OP3 thread or OPO
5. ADB installed (whether that be minimal ADB or like from other toolboxes out there)
6. QPST - Check forums for download
Guide:
1. Put phone in MTP mode if not default (Some default to charge mode) Just go to status bar and press the charging mode to change to file transfer
2. Place file from PRE-REQ #3 in a folder you'll remember
3. Reboot phone (or shut down) and when coming on hold Vol Down+Power for a few seconds and let go
4. Boot into TWRP
5. Backup (If you don't have a backup of EVERYTHING at this point, probably a good idea to do so)
---If you do take only EFS
And install file from #3
6. Restart into System
7. Open up your CMD and run this ADB command :
adb devices
adb shell
su (you will get pop up on your phone to give root authorization for ADB, authorize it)
setprop sys.usb.config diag,adb (this will open your OP3 diagnostic port)
Click to expand...
Click to collapse
This forces it into DIAG mode, check your Device Manager to see if you see a port connection displaying a COM PORT.. IF NOT, you need to install drivers--Search thread for drivers, likely will be find in original OPO or OP3 thread.
***********THIS SECTION IS PURELY PRECAUTIONARY*********************** SKIP TO 11 IF YOU WANT
Purely precautionary we did not have to restore any QCN as they do in OP3 due to encryption:
8. Install QPST, open QPST
Now fire up QPST and go to "Port" tab, and choose "Add New Port" ,
9. On "Serial/USB Port" tab, unchecked the option of "Show Serial & USB...bl bla bla" option, you will see your phone listed there as a "COM#" (# is a number depending on your PC) choose it, and click "OK"
10. Now choose "Start Clients" from the Menu tab above, and choose "Software Download"
**********************************************************************************
11. CLOSE QPST. Open up DFS Explorer, when the signup option comes up it is up to you whether or not you want to register for an account (Good to support them since it's a good application) If not, press the X and the app will be there
12. You should see your PORT listed as you did on QPST. Double click on it (If you can't; confirm QPST is closed otherwise you won't be able to connect to the port) You should see it turn green and highlighted ONLINE if you successfully connected
13. Go to the "Band" option then click on "LTE"
14. Press READ; Give it a second and you should see all currently enabled bands listed; If you want to compare you can go to "Network Guru" and press the 3 dots on the top right and press Band Locking and then press LTE.. Should list the same ones
15. Check the additional bands (Just because it says it's enabled, doesn't mean hardware wise it will work due to chipset hardware limitations; This is why as you all do this if you can confirm which bands for you connected and/or didn't connect we can keep a running list.)
16. Press "Write"
17. Since we're in Demo mode it will count down and then in the LOG box you'll see operation successful
18. Restart the phone at this point and disconnect the cable
19. Wait until it boots up again and go to "Network Guru" press the 3 dots again and go to Band Locking and you should see the new bands listed
*If you don't press the 3 dots and press Clear forcings and it'll prompt that a power cycle may occur; That's okay, let it, mine did, wait until the phone comes back up and repeat 19 and the new bands should be listed.
20. LET US KNOW ON THIS THREAD what bands are working, what aren't. It will allow us to further play with the device to discover if there's limitations or if further editing is required like in the OP3.
*Please press THANK YOU if this guide was helpful.
**Sorry for the missing of some info in the guide! Seems when I added the HYPERLINK it removed most of the other text before it so it started at #4 instead of the remainder of #1-3

Direct link to RMT STORAGE PATCH:
Rmt Storage Patch Zip

usb debugging should be enabled i think, you didn't mentioned that. " (this will open your OP3 diagnostic port)" and here should be op2 i think. thanks for thread, i have a2005 and want to unlock 20 band(800mhz), will try asap, now i have exams running out of time. btw, so the risk of breaking phone is low right, this steps only modify EFS partition only? so hybrid recovery and flashfire can backup/restore if enything goes wrong

What is the benefit from this? Better reception?

Still something is missing
Hi, I think something is missing. Let me describe what I have done on a A2005:
1- I downloaded the rmt_storage from the link provided on Pre-reqs #3.
2- I backed up EFS, installed the patched rmt_storage, reboot into system.
3- I installed the modified HTC modem driver as unsigned driver, did the adb diag port commands, and the phone is recognized by DFS.
4- On DFS, I must click on SPC 000000 since the log shows errors. I'm not sure if a specific SPC value is required ***
5- When I click on Read, it captures the values, I wanted to add Band 3 (1800) so I checked it and then clicked on write. The logs showed that the write was successful.
6- I restart the phone, connect it and load adb diag port commands again, load DFS, click on read and the values stay
7- When I open Network Guru on locked LTE bands, the list shows me the previous one, as if nothing has been written. I restarted the phone already several times, still no LTE on Band 3.
Besides the SPC code, I might think that:
- The rmt_storage somehow it's not working
- DFS keeps the values but they are not reflected into Network Guru or phone. I already set 4G/3G/2G enabled on the connectivity options. No changes
- Maybe there is another value that needs to be changed with another tool such as QXDM
Any help would be very appreciated!!!

In Network Signal Guru, choose clear forcing. And check the LTE bands again,
or, install Network Signal Guru after you done unlocking, else it will show what it remember on previous set up

the guide forget to mention that u need to flash rmt storage patch before do any modification,
else no mod will be saved (will revert upon boot)
the patch is in my OP3 thread

Thanks! So today's update:
1- I connected the phone again, ran adb commands, reviewed the bands again on DFS tool and settings stayed. I'm pursuing to enable Band 3
2- I uninstalled Network Signal Guru
3- On Recovery, flashed again the patched rmt_storage, boot the phone, wrote the values again on DFS tool. Reboot phone
4- I installed Network Signal Guru and now it's showing up on the bands lists. I unchecked the bands default on A2005 and used the ones from Eruper/Asia Model as FDD-LTE: Bands 1/3/5/7/8/20 and TDD-LTE: Bands 38/40/41. My provider in Costa Rica (Movistar) uses Band 3 (1800) for their LTE. I clicked on Band locking, clicked on GSM and WDCMA and removed all checks. Then clicked on LTE and left all LTE bands in hopes that it will connect to that frequency. The list shows:
B1: 2100
B3: 1800+
B5: 850
B7: 2600
B8: 900 GSM
B20: 800 DD
B38: TDD2600
B40: TDD 2300
B41: TDD 2500
When I only picked LTE bands as checked, it never resovled to get connected to any cell base.
5- I dialed *#*#4636#*#* to access the information about the phone and monitored the signal setting it up to "LTE Only". No signal on that either
Top of my head, I will restore the qcn backup I made and restore the backup I made for EFS and start again. Now it's saving values after reboot, which is great, but not identifying anything.
Is there any log worth posting here? I read on the OP3 guide that they were restoring a qcn file with bands enabled. Is it worth trying the same?
Anyone that has LTE band 3 enabled would be very appreciated if they post their qcn backup

I have not been able to further test as all the phones I compare to that are also AT&T ie: AT&T S6 are connected to the same Bands as me so cannot test til I get to an area where other bands are available currently. Will report back as I can test, but was hoping others can test in the mean time as well.

You shouldn't need to restore any QCN or EFS, just re-check the bands you unchecked and it should pickup all the bands again. Also, confirm your APN is correct to be used with LTE?
Did you get ANY LTE Bands before this mod? Or you only have LTE on Band3?
You can use RAT locking to enable LTE Only rather than unchecking all the WCDMA and GSM bands. that way it'll force LTE, if it doesn't go to the Cellular Network tab and press the Preferred NETWORK to go to LTE ONLY.

sadly for me nothing happened, i have a2005 and want to add band 3 and band 20, did everything 2-3 times whats in a guide, everything went well, write process was comlete but bands didn't added

When you say didn't add, you don't see them in network guru or you see then, but unable to catch signal on them?

You tried to force clear in network guru? If so, when you reconnect and enter diag mode and go to DFS, press bands and LTE, press read, did the changes you made stick?

Just so ppl around here know... there is old forum about band OPT band unlocking with various trials of changing bands, which failed, due to missing RMT patch OR BUT it got MANY juicy info !!!
in the past other users sent me qcn/qcnx files of the EU and CN models ( credit: whoever sent me these files from the old thread ) - I hope this help you out.
keep up the good work ! :good:

Have you tried what we said here? And tried to see if you can band lock on 3?
I'm going to see the qcn based off of the op3 guide as well as they had to do qcn restoring.

not yet...it will take me some time, i'm a master's student in exam period.
nontheless, as you can see from the old forum, i'm really interested in opening LTE band 3 on my A2005.

Thanks guys! I live in Venezuela and we use band 3 for LTE and I have the EU version. I'll try this guide today
EDIT: I tried without success, I did all the process but i do not have LTE signal on Band 3. On Network Guru, Band 3 appears as supported. I tried RAT locking but It keeps without signal.

Thank you for the qcn files. I've tried it, and it overwrites my imei, which is expected. Then I tried to replace the imei with mine by hex editor, but flashing the modified qcn still overwrites my imei. We may get into the same trouble with op3, which is the imei encryption.

[Guide] Enabling additional LTE Bands on the Galaxy S7 with U firmware

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) With the Android Oreo Update, you no longer need to insert a US based sim card, to enable Diagnostic Mode, just dial *#0808#.
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) (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)

}
3. Once Reboot, go to the phone dialer, enter *#0808#, a USB Settings screen like this will appear. Click your home button to go directly to your home screen, do not click back.
4. Remove Sim Card, insert your carrier sim and reboot the device without closing the USB Settings (if your carrier is one of the above skip this step)
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.
18. Say thanks if successful.

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.
3. Once Reboot, go to the phone dialer, enter *#0808#, a USB Settings screen like this will appear. Click your home button to go directly to your home screen, do not click back.
4. Remove Sim Card, insert your carrier sim and reboot the device without closing the USB Settings (if your carrier is one of the above skip this step)
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:

Why more LTE bands ?
OK, please fill me in, I have u firmware and hotspot and I love it. I rooted my old phones and know enough to probably brick a phone although fortunatly I never have...Knock,knock... Why do I want more LTE bands, I travel over the road all the time and I am constantly in and out of signals, will this help my data, or signal in remote areas or am I totally lost here?

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

Moto Z LTE band issues after 7.1.1

Hi All,
Recently Moto has pushed 7.1.1 update for Moto z. But as always, update is not flawless. It seems like LTE Band 5 and Band 40 is not working after the update. It works fine on Band 3 though.
If you guys have the same issue of 4g, kindly do the following and post the band number (or LTE frequency) on which it is not connecting.
1. Install the app LTE Discovery
2. Remove sim tray and open LTE Discovery.
On right top box, you will see LTE information as shown in below screenshot.
{
"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_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
3. Now insert the simtray with your sim in slot 1. You will see the app picking up information. (Note: be quick to take a screenshot or remember the band number. It will disconnect shortly. If it disconnects before you could get the band information, repeat the steps 2 and 3) If you have successfully taken a screenshot, it should look like the below pic.
4. Now post the Band which is not working in your phone and the Band that are working (If the Band is working, it should not disconnect immediately) along with your software channel.
In my case, Band 3 is working and Band 5 and 40 are not working. Mine is RETIN.
PS. If you cannot view the image, please download the attachment as a zip file.

Same issue since 7.1.1
Hi,
after installing 7.1.1 this morning it seems i got the same issues.
My little network strength display triangle shows a very small x on the right side, and no mobile data flow.
If connected to HSDPA everyting works fine, as well phone calls are ok (no phone via LTE here).
Talking to a technitian of my provider (Hutchison 3 Austria) he told me he could monitor my phone trying to connect,
changing between 4G and 3G but no data flow.
Now, LTE Discovery shows my Z jumps between Band 1 and 3, but not establishing any stable connection.
Softwarechannel is 'reteu'
Talking to a Motorola online help chat they just told me to send my Z in for repairing (after it didnt work in safe mode as well).
Now, what to do?
P.S.: its already my 2nd Z, as my first one crashed its SW and after restart had excellent 4G internet, but no more phone working, as it didnt switch back to HSDPA or 3G

4G/LTE issue after 7.1.1. update - Moto Z
Hi,
This LTE / 4G issue is the same on my Moto Z too after the 7.1.1. update.
Only 4G/LTE not works, 3G/2G works fine... but who use those?
I've contactet the US and the Europe Support of Motorola too.
And after reading a lot of topics about this problem, I said them, to make a fix for this, because its a global issue, and lot of people just can't use it's 4G/LTE mobile network.
They told me to go to my service provider. I did it, we tried my SIM card in other mobile brands, 4G works perfectly, only the Moto Z can't connect to 4G/LTE.
As U guys said, yes the LTE Bands are the problem on our region.
For example, my case is the following:
Region: Hungary
Service provider: Telenor
Bands that are have to be enabled/supported on this region with this service provider: B3, B7, B20.
I tried the LTE Discovery app too, and I saw that my phone trying to connect to the B20 and B3 but not establishing any stable connection.
At the moment I really don't know what can I do.

Hi, I am from India. After the update, my phone worked fine.. I was very happy, but I came to my hometown for the weekend. On my way, signal dropped. And since then I am managing with wifi. My carrier is a 4g only carrier. I don't have any other number too. I really hope to get signal back in the place where I work. (Band 3 seems to be working in RETIN device).
I am quite sure this is a minor bug on the technical implementation front. Moto can fix it in a week, if they come to know about the issue and it's seriousness. Being a well established brand, this is definitely not a thing you wanna do. It is a blunder by Lenovo owned Moto.

The same problem in Poland. No internet on B3/B20. LTE at B1 works (other provider).

Is there anyone in the USA that is experiencing these LTE issues since installing 7.1.1, or is this purely an international issue? So far since installing 7.1.1 the only problems I've encountered were screen freeze/reboot. But as far as my LTE strength with Verizon Wireless goes, everything is status quo.

I am in the USA, using att, and after updating to 7.1.1 I had the phone set to 3G only here and it was effectively stuck with no option to enable LTE. A network reset fixed that and now I am ONLY on LTE and often it seems to lose the signal. I will try to run the diagnostic tool today. Seems it is a problem on Lenovo side for sure.

Same issue for me in Hungary (B7 connects well in the downtown area, but suburbs only has B3 and B20, those don't have any data connection at all).
I started a thread on the Lenovo forums about this, and many users confirmed, but still not reply from any official Moto account. I also tried the Moto UK support by email, and they said if factory reset doesn't work (no it doesn't), i should send the phone in for repairs. Since my phone is from Germany, that would be quite a hassle
Has anybody tried to downgrade? For RETEU models there is a 6.0.1 fw version available that would be installed via mfastboot. Or maybe just the radio modem...?

Don't try to downgrade to M, it will brick your device because the bootloader has changed from M to N. You can flash the RETBR N firmware via fastboot or RSD-lite. This is the only way to revert to stock 7.1.1 for RETEU devices. The softwarechannel changes automatically into RETEU after flashing and, once booted, you can take several OTAs until 7.1.1.

If you had issues with 7.1.1 you could stay with the latest 7.0, witch is NPLS25.86-30-12 and don't accept the 7.1.1 OTA.

I have the Moto Z force from verizon and after 7.1.1 i can not connecto to LTE 4g,
I'm using this phone with T -Mobile, but i was working fine before the update..
Any news?
Thanks

Band 7 and 8 missing
Getting Band 1,3 and 20 here in Czech Republic with Vodafone.
Band 7 and 8 are missing, as well as the complete absence of LTE-banner, enchanced LTe and VoLTE.
Been using LTE-discovery-app to log, as well as a brief switch of provider (Telenor) to confirm. Have also reported in the Lenovo-forum.
mirrormurr

This is still an ongoing issue for me. I guess we just live with it dropping the connection and not having full LTE support until the next update, anyone who had their device "serviced" have any better luck?
Well, I ended up sending mine off for service and I am on 7.1.1 from the factory on retus.
My problems seem to be fixed. I'm still pretty salty about this and will likely wait eons before Oreo if it ever drops.
