I've found a variety of posts throughout XDA regarding changing or adding LTE bands to a phone via Qualcomm's software. I'm wondering if any of these are an option with tethered CWM on the PadFone X Mini.
Has anyone tried this? A few things I've found:
All-in-one tool, flashed in recovery
Possible way to enable USB modem mode
Changing configuration of Qualcomm modem to enable additional bands
I'm wondering if the all-in-one tool will do it. It seems like with root and recovery (even tethered), we shouldn't necessarily need to figure out where the diagnostic menu is to enable USB modem mode...
ETA:
So I did a little more poking around, and it looks like AT&T and T-Mobile use the same LTE bands/frequencies, so the issue may be the radio's baseband firmware. If this is the case, has anyone tried alternative baseband firmware for the radio?
I am interested in reprogramming the Qualcomm wireless modem on a OnePlus Nord 10 5g. Anyone help with where to start?
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.

I am facing same issue regarding back up nv at 12%

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 ?

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.

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

Yes 4G is the big pb, i found that DFS Tools write 3G bands but for LTE, the issue is in BC Config Div, need SPC code
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.

Thanks for your help,
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.
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!

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

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?

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.

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 !!!

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.

no success every time.these artical are very helpfull for me to
get the main idea and communicate direct with the pones modem and
unlock lte band cause they all are lock or restrict with

1.root the device (necessary only if you want to see which lte
bands are open in your device with the help of network signal
guru apk)
2.install adb and fastboot driver(enable usb debugging)
3.install qualcomm driver .(google it) and write mi5.qcn file
with the help of qpst software after dialing (*#*#717717#*#*)to
enter diag mode.
4.change the value of line 06828 (lte_bc_config) to 2061853925599
but believe me guys there is no succuss every time edited the
same.
next step is all my... i search and edit my self and unlock lte
bands which i know how important for me.many people struggling
like me to unlock but they are far away. i dind't prove here that
iam genius, but i work very hard to achieved.please do not copy
and modified this artical.if you like my work than hit like
button:good:.
5.one thing i clear to all iam not responsible if your device is
bricked due to any wrong step. plz read carefully to avoid. lets
play with lte bands plz go to line no 65633 that is lte band
preference line. and feel free to change the value after read and
change it to 0x111101E111110045 and write. plz follow no.4 step
also before to do this(plz copy the original value in safe place
if any thing goes wrong than revert back with that easily.
all done:angel:
after that restart the phone as regular restart.i personally
tested this on my mi5 64 gb there is no need to root the device
cause you found signal that is important even not to see what lte
bands are working after follow this....
this is only my hard work not a copy of any other person from
this and other forum, and all credit goes to me only lol>>..:laugh:
if you want lte band of your choice then plz. use nv calculator
to find your suit.and replace with value of step no. 4, any doubt please ask.
Tried it but doesn't work - I only see LTE band 7 as before. Can you post screenshots in an app like Network Signal Guru?
Hm, it's interesting, but can you share some evidence of your work? Like Signal Guru screen and overall explanation?
I Would try that after some proofing screenshot.

Can you include your rom version? I think this work for developer rom while most global isnt supported.
hi OP, any screenshot proof?
****DISCLAIMER****IMEI will change. Please follow procedure and change the IMEI of your own. Any damage may happen will be your own responsibility.******
Hi All,
I stay in Pune and Vodafone 4G never worked for me as 3s Prime (Land) doess not support LTE Band B1 (2100mhz). I thinks its same issue with other states like Chennai as well. Not sure though.
I referred to many guides to unlock LTE band which I did but still it never worked.
Luckyli a thread by @bharatg http://en.miui.com/thread-299779-1-1.html caught my attention. In that thread there is a QCN file backup for IDO.
I tried it and it worked for me. Vodafone 4G is now compatible with my 3S Prime. Several other bands are also unlcoked which makes it a global phone now (not fully but almost). All credits goes to @bharatg and "Thanks to @RR_30 for helping me with the QCN file. Also Thanks to @candicesu and @technoking2020" as mentioned in his thread.
Step 1) Root required (Only required for Network Signal Guru app which we will use later to activate and lock LTE B1)
Follow the guide linked above. All steps must be followed. Don't disconnect phone from QPST until it confirms restore is completed. Bcoz, it will say 100% but it take a minute or two more after it show 100%.
Once completed, reboot phone and open network signal guru app. Click on Lock bands option, select LTE and you will see several bands are now activated. CLick on first option that is LTE 2100 B1. Click ok to confrim.
Profit: Vodafone 4G will now be detected. Turly this will be a global phone.
So, we can use Redmi 3 (IDO) QCN file to unlock our Redmi 3S (LAND) band?
Anyway, thank you, will try it (just to unlock, my country use the other band which is pre-activated by Xiaomi, so no need to unlock actually)
hello. i need to unlock LTE Band 4 AWS (1700/2100Mhz) on my Redmi 3S 2016030 . can you please tell me if this method unlock that band?
Followed each and every step, now my device shows NO SIGNAL in both the sim slots! Forget about 4G, not even 2G works now...

There must be a misconfiguration when you're doing this tutorial.
Maybe you can try this to revive your signal : http://en.miui.com/thread-315019-1-1.html | http://www.mediafire.com/download/0k35nqs1ga1bc85/Xiaomi_Redmi_3s_QCN_File_IMEI_800000000000000.rar
That worked!

That worked! Flashed the qcn of Redmi 3S over Redmi 3. I got my network back.
Please explain detail steps

Please explain how did you revive your phone signal in detail ....as it would be helpful for me as i am facing the same problem on my device redmi 3s prime
Interesting topic, thanks for resurrecting it, I hadn't seen it.
Is there any way of unlocking the LTE band while keeping my original IMEI? Thanks
CAUTION!!!: The method described DOES NOT work and will get your phone unable to call or use mobile data. I was trying to unlock bands to see if I could activate the LTE 800 band but luckily I first created a backup of my qcn file before attempting to install the qcn provided.
I was able to restore it and recover signal. Some mod please LOCK or ERASE this thread, I can see people turning their phones into a Wi-Fi only minitablet doing this.
Anyway, B1 (LTE 2100) should work in every 3s. B20 (LTE 800) works fine in my phone (as it is international version).

Yes the B1 band is available in the Chinese version too. B20 is absent for I haven't had any problems so far in Spain.

How did u backed up your qcn?
It was very intuitive, if you follow the exact same steps as the guide that was linked in the OP, instead of restore you should choose the option to backup.
It's important to choose the file format .qcn . In any case, it's quite straightforward to do and I'm quite relieved I did. I'd like this phone to keep phoning a bit longer.
Use this guide and QCN https://xiaomifirmware.com/guides-and-tips/guide-how-to-restore-imei-on-redmi-3s-3x/
As mentioned in previous post take backup and then restore.
Tried and tested on 3S prime and it works
