1 my NV items will be kept in EFS until a factory restore including erase EFS partition to trigger factory EFS restoring.

so OTA upgrade will be fine, but next factory image whole reflashing will erase nv items in this qcn.

That is MOTO design while LG NEXUS5 have not such issue.

2. NEXUS5 D820 can enabled band3 band8 in the same way if you are in track of http://xdaforums.com/google-nexus-5/general/radio-enable-lte-band-3-nexus-5-d820-t2928561

but qcn in that post will NOT bring CDMA+LTE 1xSRLTE dual-stanby working, it is still in LTE only mode.

why NEXUS6 support 1xSRLTE is come from facotry by default, DI4.0 new modem firmware and trigger by right carrier_policy.xml from m_bing.

Hmm, I seem to remember my line 6828 was the same unknown value before I changed anything. Stock. Then when I flashed your qcn, it became the 1099830466655. I have no idea why my phone came with less bands stock. :confused: it is XT1103 Bought from moto US store. :confused::confused: no way to test it either, until I am out of the US :(

XT1100 to XT1103?

Is it possible to convert an XT1100 to an XT1103? Is it a hardware thing?

I would like to enable band 2 and 4 in the XT1100, is that at all possible?

I have both an XT1103 (borrowed) and my own, an XT1100. Could I copy the NV values from the 1103 onto the 1100? Would it cause any damage to try?

I dont mind formatting, but I also don't want a brick.

Thanks,

Hi. A quick question. In post #33 last paragraph you say that "...but according my knowlege in NEXUS5, to enabled band 17 and band 20 at the same model will NEED addtional components in RF Front End hardware design.." Do you mean Nexus 5 or Nexus 6? Because I have Nexus 6 XT1103 and want to activate Band 20. Please help.
[Nexus 6  General] Azlun:
Yes, I mean both. Please note since Nexus6 RF front end schmatic is not in my hand, l just guess it for nexus6, but nexus5 is 100% sure.

Firstly, thanks for efforts. This worked in my xt1103 in Turkey, Vodafone TR. But whenever it drops to 3G, the phone can't connect to 4G automatically. İ have to do this manually, is there a solution for this bro?

By the way, İ used b1-8-9-19-20-merged.qcn file on my phone.

Solution for QPST error "roaming list receive failed" or "roaming list could not be read": remove SIM card or put in SIM card from other carrier while using.

[Nexus 6  General] sanju_barc:
Hello seniors,

I have Sprint HTC M8 & M9 with LTE band 25, 26 & 41 enabled by default. My carrier here in INDIA uses LTE band 3, 5 & 40. I tried enabling these bands by writing corresponding NV values in NV item 6828 & 6829. NV values stayed written even after reboot but, required band did not enable.

Please guide me. Is replacing QCN file(indian version which contain band 3, 5 & 40) necessary? If yes, where can I get these files for these devices? Pls help if someone is aware.

Thanks

Hi guys, I'm currently running a Nexus 6 and I'm in the proces of enabling the rSAP protocol.

http://www.android-rsap.com/41-support/128-enable-qualcomm-sim-access.html

Somehow, I think I can't get the phone to boot into diag mode (boot into bootloader, BP Tools, power). It boots like normal.

QPST doesn't recognize the phone either, but I do have mdm_diag in device manager. But then, the driver fails to install.

I'm running WIndows 8.1 with the latest QPST program.

XT1100 Band 38 TDD

Not sure if Azlun is still checking this thread or not but... How do I enable Band 38 ( TDD ) and keep all other bands enabled ? I'm using XT1100 . I used both QXDM & DFS tool to enable the band, when I check it after a reboot it still shows as enabled, however LTE still does not connect on band 38, but it does on 41 ( carrier uses band 38 ), and whenever I do a phone call the phone does not switch back to 4G. Or can someone help me with the .qcn file for all default bands on XT1100+band 38 TDD ?
[Nexus 6  General] SebaTuren:
thx for this!, I can't speak english very well, but, I only said thx for this!, I'm liveing in Chile, and use WOM, Ban 4 LTE, and every working, Android 6 now Android 7 :D

Thx!.
[Nexus 6  General] Azlun:
yes，you can use DFS 14.x to tick the LTE bands. Or QXDM-NV Browser to write NV06828 or NV65633,keep the bit as zero in binary.
[Nexus 6  General] Azlun:
Interesting topic, keep me in if you have good user case. You can set your win8 as force driver install mode by F8 Options when windows boot manager is on display. Then use my driver installation step here.
[Nexus 6  General] Azlun:
Sorry for miss you all for long. Since band 38 is. Sub band of band 41. You phone is default support it. Most network and your phone support MFBI to let your phone use band 41 to connect to a band38 network.

I think I replied,band20 has less hope on xt1103 even I have shared that Rf NV in qcn at this thread. Just try it to see.
[Nexus 6  General] duttyend:
Dear Azlun,

Thank you very much for your time and consideration.

I have a XT1103 and use it in Europe. I tried activating band 20 with the file you posted (B1/8/9/19) knowing it was unsure and, indeed, it doesn't seem to work :(.

If I understood correctly, you explained that it might not work because it was too close to other frequencies in our modem, so my question is :

Would it be possible to sacrifice one or several other bands (even all others if necessary) to make room for B20 if we need this band above all others ?

Thanks again and have a great day!
[Nexus 6  General] Azlun:
No, my reason before was not means about PCB size. I was said b20 is a band need dedicated pa,possibly like nexus5 case. And, do you try my b1/8/9/19/20 file?
[Nexus 6  General] Benzema9:
I just got a new Nexus XT1100. Would I be able to activate the LTE bands for T-mobile or would I have to buy the XT1103? Thanks for your help.
[Nexus 6  General] duttyend:
Thank you for your answer.

Yes , I used your B1/8/9/19/20 file several months ago. Did you make a new one? because I can't find it anymore in the thread.

Yes, I know you didn't mean that PCB size was the problem. What I meant was if sacrificing/disabling some LTE bands would make it easier to enable B20?

And the last question :p : would it be possible to enable B28 for LTE 700 Mhz?

Thanks again and have a great weekend
[Nexus 6  General] Azlun:
It is a pitty,have to answer all your question.NO,NO,NO. only one that file you used . Disable other band can not help band20 enablement. Since rf front end hardware today still a hardware depend issue. And b28 also a band need dedicated rf front end hardware as my knowledge.
[Nexus 6  General] duttyend:
Thank you very much for your answers!

What a shame that those bands need special hardware :(

I need an advice here.

Even after reading this thread, I still have some questions to make sure if I really understood everything right.

My issue: I got XT1103 and my GSM service provider is operating only on 1800 and 800 LTE bands.

According gsmarena

So is this from OP

What I need to enable Band 800 LTE?

I have some experience with flashing etc, but I never played with bands before and I do not want to loose 1800 instead of gaining 800 :eek:

Also, I am interested if there is any application, which gives information about bands of the device?

I tried a dozen but none of them is showing bands.
[Nexus 6  General] Azlun:
my qcn file just add 2nd list bands onto offical bands,you will not lost band3,you can flash it. For 200% safe,you can backup efs.

And I want to remind such rf front end bands will be filtered by efs/policyman/carrier_policy.xml if you found this file on your device by qpst-efs explorer.

You should awake that which band you are targeting to. 800 LTE bands can be band5,19,20, or 26 in different carriers expression.

A apk tool can display device support bands,required root.

Search NSG in Google play, it is named Networks Signal Guru, it's unlocked band function may not works for enabling unofficial support bands, not need to try. But for official bands controll I guess it works.

Due to the restriction by the china gov and my study .I haven't been to this website for 2 years! but when i see your word i feel very very warm!
[Nexus 6  General] relaxable:
Big thanks to OP for this work! I have used it several times on 2 Nexus' to add the LTE Bands. Just did it again today as I wanted to try newer radio (flashed the last one from Google's factory image for 7.1 - have hesitated updating the radio because would lose the added LTE bands, I think....) Anyway, everytime I do this, I always have trouble with the process somewhere, so I thought I would add this post here to help myself next time and maybe help someone else also to clarify some of the steps from the OP ---

This will start at Step 3, so assumes already that have obtained the QPST, and installed the moto drivers for the diagnostic interface.

Start the phone up to Bootloader, and use the volume button to move the boot selection to BP Tools, and when that shows, press the Power button - the phone will reboot & start normally. (I had to use an older AOSP ROM today as the custom Oreo ROM I was using would reboot when connected to PC with the BPTools activated...)

Phone connected to USB port on PC.

(Device manager will show the COM port(s) for the phone - in my case, 3 ports, COM10, 11 and 12 all showed)

Run QPST Configuration program. If any ports are showing, REMOVE them all.

Then, ADD Port & you should see the port(s) for the phone. You can do this multiple times to add them all, although only 1 of them is actually needed - but has to be the right one.

Once the port added and showing in the QPST configuration window, go to the 'Start Clients' menu item of QPST configuration, and select 'Software Download' - This will open up the new Software Download QPST Window, with your phone shown as connected; Use the Restore tab, and select the patch.zip file that adds additional bands (links to download those files in Post 1 & 33 this thread). Won't work unless the 'Allow phone/file ESN mismatch' is checked.

Having Band 1 has been so helpful when travel in Asia and getting local SIM card!!!
[Nexus 6  General] BigM69:
If I can add LTE bands for Verizon on XT1100. I also plan on rooting and unlocking bootloader. Do i need to root before I add the LTE bands for Verizon, and if I flash custom roms will I lose the bands I added?

Thank God I found this site! I bought the XT1100 on eBay by mistake. I tried to get a refund before they shipped it but was to late. I am on Verizon, I may need some help adding the LTE bands when my device arrives. I'm so Glade I googled this. I clicked the attachment for the XT1100 file but it doesn't download. I'm needing to go ahead and download the file I need so I can set up on my computer that way when my XT1100 arrives I'll be ready to go with the installation. When I get my XT1100 I'll pay someone to help me add Verizon LTE bands! Please message me if interested.

LTE Band 2 and 4 enabled and working on XT1100 in 2018!!!! YEAH!!!!!!

Not sure. I am guessing yes. However, I was able to accomplish enabling Band 2 and 4 TODAY on XT1100. I am on MINT Sim and my LTE works flawlessly.

I am trying to figure out however...to be a bit more greedy :p:p and see if I can somehow add the third band for Tmob and Verizon (12 and 13 respectively) in this puppy. Both 2 and 4 should work with both providers.

Since this is the only thread that every single user from everywhere (Reddit and other sites) keeps referring to, way back from 2015, and since OP has stopped being active, at least on this thread, I am guessing there has not been any updated work on this.

With custom 8.1s, for instance, will flashing a custom over the AOSP I have make me lose my lte privileges? THAT is my biggest question.

Anyways, if you need instructions, the OPs still hold true. I would be happy to tell you again what I did.
[Nexus 6  General] wavedashdoc:
I also bought a XT1100 64gb (deal of the day amazon for $180). I currently have the Verizon Variant Nexus 6 but would also like to enable all LTE bands (2,4 and if possible 12 and 13 on the XT1100 for Verizon. Can you please explain your steps? The OP is a little unclear.
[Nexus 6  General] sdg1980:
Thanks for that offer. I too had MintSim and had no issues like you. I was able to enable Band 2 and 4 a while ago (as you said) but strangely, currently, I don't get to text or call on Total Wireless/Verizon network but only get LTE data. So I am depending on Hangouts for wifi/data calls.

May be enabling Band 12 might help (?) for those on Total Wireless. Thoughts?

The 1103 has same bands as the 1100 for the most part, so I'm not sure what it where is the issue with calls on Verizon network for 1100
[Nexus 6  General] wavedashdoc:
I was able to activate all required CDMA and LTE Bands on the XT1100 following this guide on XDA.

The phone reports all the required bands but I think it's verizon that is seeing this IMEI number and blocking it from full network access. I have LTE, but can't make a call. My next step is to either take it to a Verizon and try to get them to activate it or call customer service. Customer Service might be a better option as I can hopefully get a tech that understands.

Hope this helps anyone in a similar situation.

Edit: I also used this site for a guide on all the bands I needed to activate.
[Nexus 6  General] sdg1980:
I've never used post paid service on Shamu, so I've never been able to use the 'full' Verizon network, if that's even a thing. Total Wireless being MVNO is perhaps blocked from using some specific bandwidths of its parent network.

From what I was told, Total Wireless needs 850 gsm to facilitate calls but my 1100 already has that (?).

I unlocked my bands using QPST tools, as per the OP from China/Azlea, specifically tailored to N6. Does the generic Qualcomm bands unlocking links that you provide do more/unlock more bands for Shamu? Have you tried both?
[Nexus 6  General] wavedashdoc:
Yes you can unlock all bands available on the device with the DFS tool. I still haven't had any success with calls. Tried talking to a Verizon chat rep, they refused to activate the phone. I think I just need to go to a store and try at this point.

[Nexus 6  General] Viva La Android R.I.P.:
Works flawlessly for enabling LTE Bands 2 & 4 on the International Nexus 6 xt1100. This enabled T-Mobile's 4G/LTE data, a GSM-based network that utilizes LTE Band 2 (1900MHz), Band 4 (1700/2100MHz), Band 5 (850MHz), and Band 66 (Band 4 Extension of the 1700/2100MHz Spectrum). T-Mobile's 3G (UMTS/HSPA) frequencies are covered by Band 2 and Band 4 as well. Band 2 is likewise used on 2G (GSM, GPRS, EDGE) for voice or data, but not voice & data simultaneously.

This mod makes for the perfect solution for T-Mobile, its subsidiaries and MVNOs on the XT1100 Nexus 6.
[Nexus 6  General] wintoon:
I have been looking into this and please correct me if I am wrong. IN THEORY, I should be able to load up the NV values for BC4 on an XT1103 and copy them onto a XT1100, I dont care if other bands on the XT1100 stop working. It should be straight forward in that sense? Am I correct?

I believe this is exactly what you are doing in order to enable BC1 on the XT1103?

Thanks, and sorry for all the posts.

I dont think the newest version can be modded.

To tell you honestly the thing is enabling bands on a phone that doesn't have a hardware for it won't do good if yout just gonna stack it up with a software..it doesn't do good at all..after using this bands it made my signal useless and even though i had the lte its not what its capable of being the lte i wanted it to be..
[Nexus 6  General] _Dennis_:
So I tried this on the 95R radio. It seemed to work, only 2 unknowns. I'm not able to check band 1, being in the USA still. And I'm not able to ensure band 12 works as there is no band 12 deployed near by. So far bands 2 and 17 from AT&T works, and I'll check T-Mobile's bands in the area later.

and Band 1 and band 8 or Band 1/9/19 or Band 1/8/9/19 for XT1103 View attachment XT1103_B1_B8_B9_B19_Patch.zip

to trial.

for new comers HOW TO questions, please read POST#1 first, just replace the qcn files attached named with the band you want.

I have never test these qcn since no such band signal in my city, So YOUR feedback after 1 day test is preferred

Your sucess will lead me to update the POST#1 1-stop with full info .

AN important NOTE for XT1103 band 20, the fact is I have attached

XT1103_B1_B8_B9_B19_Patch.zip\XT1100toXT1103_RF_LTE_B1_8_9_19_20_Merged.QCN here,

but according my knowlege in NEXUS5, to enabled band 17 and band 20 at the same model will NEED addtional components in RF Front End hardware design, so mostly , XT1103 enabled Band17 will NOT support band20.

so you are free to try XT1100toXT1103_RF_LTE_B1_8_9_19_20_Merged.QCN, but do not have too much hope to get band20 works.
[Nexus 6  General] Azlun:
According to NEXUS5 experience, such method can also applied on Android 5.1, and I can see a later post here mentioned,

95 Radio, that is latest radio works....

for the link pakgamers.com in fact that source is from same title post in XDA GS5 forum member fffft,

I believe that can works for some models for some band, but not all.

the key point is, those method only config rf setting nv, but not patch to add RF nv lack to make Rx and Tx paths do their job correctly.
[Nexus 6  General] Azlun:
you means band 39 and band 40, I have to say NO, as I explain you may see on bbs.gfan.com NEXUS5 forum you may see RF tx rx paths need filters to remove noise from band3, so mostly MOTO will not keep it in NEXUS6 XT1103 but provide it only on X Pro XT1115.

[Nexus 6  General] Azlun:
Which qcn I sent make your xt1103 works? Thank you to share.

About LTE discovery, the app does not tell real band from modem, it just guess your band according your last two digit 66, since moto do not have a field test to display real band, so you need qxdm to monitor it from PC, search my words in forum to find the menu path in qxdm.
