Phlipines Smart should be in band1/3/5 ,but it is not in records your GCI surfix 66 relative to which band,

to help LTE Discovery for static source, you need QXDM to read the truth band and give email feedback from EARFCN-tap to see "Report" button to send email to developer for later release.
[Nexus 6  General] arregull:
Hello. Yes I sent an email to the dev for future release. Thank you so much. :) Your contribution to the nexus 6 community really helped a lot to us XT1103 users. :)
[Nexus 6  General] joaquinpb:
Thank you for your work!!

This is working perfect here in Argentina. B2 I think.
[Nexus 6  General] Azlun:
let me share the XT1103 and XT1100 B2/4/17 nv items for your to compare in xml text.

I am sorry I can NOT share QRCT Tool. it is only for QCOM licensee.

Argentine operators are deploying LTE on band 4 (not band 2) in urban areas. Their plan is to get LTE on band 17 for rural areas in the coming years. Eventually they will reuse bands 2 and 5 for LTE which are now used for GSM/WCDMA.

It's good news that you could enable band 4 on your XT1100!
[Nexus 6  General] Azlun:
I think you should already trial my B2/4 qcn. If it works, please comment the file name and you USIM operators.

then, you are just asking for band 12 now? Should band 17 will work for it? I am still not sure band 12/17 is support in XT1100 RF Front end hardware or not.

Another question, do you have some rules about Argentine GCI surfix coding vs bands ? If so, then LTE discovery app can integrate such rules to guess LTE bands for all Argentinese...
[Nexus 6  General] jasalta387:
Sorry, I meant band 17 instead of band 12. I corrected my post.
[Nexus 6  General] Azlun:
so, you can have the way to do it yourself,

1 Download NEXUS6 XT1103 B2_B4_B17 RF NV.zip

2 find the B17 qcn and restore to your XT1100

3 use QXDM-View-NV Browser-06828-read-Write to modify your NV06828 to a value enabled band 17,

NV Calulator is an apk tool can help you to calculate is in Google Play.

please note, above method is assuming that XT1100 RF Front end support Band17, but mostly the band 20 compoments have have confict with band 17, that make it not works even you have all Band 17 nv items in phone.

I was wondering.. Is their a way to get LTE band 12 on nexus 6 XT1103 this is the international version on course
[Nexus 6  General] Azlun:
XT1103 is us version support band12 by default, did you asking for band 12 for XT1100?
[Nexus 6  General] chronos00:
Thank you Azlun for all this effort! I am looking forward to try this.

I am trying to install the drivers in a virtual machine with Windows XP, but it is not recognizing the drivers. It is fails after step 2-7.

Do you know if these drivers would work with windows XP?

I am using a Linux box, and the only windows I have is a virtualized Windows XP. Is there a way to flash the modem software from Linux?

Thank you!

i'm having hard time doing it i live here in the phil too,could you help me?

thank you
[Nexus 6  General] mimsiroll:
All i can say to help is read the op's instruction, and re-read each step. Not responsible if you wont heed my instruction. Last would be not really use it since your phone rrally cant sulport the band which doesnt have the hardware for it, and smart isnt that goof for lte..you can just use 3g for it..im using this xt1103 since im traveling u.s.

Any chance to enable CA with B3+B20 and B3+B7 configs?
[Nexus 6  General] yunxch97:
Yes, I mean to have CMCC 4G support on xt1103. I wasn't able to find the post on gfan.com you mentioned. And I don't care about noise from band3. I was wondering if

a) Are XT1103 and XT1115 exactly the same in harware?

b) Could you make XT1103 CMCC 4G compatible?

And if it's OK, please also provide a reference explaining why(maybe a previous post by you or somebody else)

Thanks.

想了下，还是把中文敲出来会比较方便

我的确是想在xt1103上用移动4G，你说的机锋论坛的帖子我没找到。。。band3噪音的问题，我无所谓，所以我想知道：

1、XT1103和XT1115在硬件上是否完全一样？

2、是否可以把XT1103搞得也支持移动4G？

你可以只给我答案，如果没时间解释原因的话，贴我一下你（或者别人）之前的帖子链接，我自己去看就行。

谢谢！

XP is OK, Linux is not workable for pubilic, only QCOM customers can have QPST Linux version.
[Nexus 6  General] Azlun:
Thank you for your offering about host ROM,but I do not have a ROM for you to host, and no need.

Answer your question,

my qcn is different from normal qcn from QPST backup, it is just an additional patch in 1-20 nv items inside it,

it add the items lack for Band1 on topic of stock NV items, it never touch your other bands nv items, that is more safe for all to use it.
[Nexus 6  General] Azlun:
I don't known, no time to research CA.
[Nexus 6  General] Azlun:
1. NOT, XT1103 and XT1105 own the same CPU and RF Tranceiver, but different RF Front defined different RF bands.

Above is my expereience guessing since I can not find a XT1103 and XT1115 service manual currently.

2 NOT, with out right HW to support band 39 and band 40, the it is not a problem about noise performance, but you will never success to communicate with the base-station, that is digital protocols..

more reference is for NEXUS5(NOT 6) RF Front end in Chinese language

UMTS/WCDMA

Hey, [MENTION=5256159]Azlun[/MENTION], really nice work! But is it possible to merge XT1100's WCDMA/UMTS bands too(NV Item 1877, bands 6, 9 and 19)? Is it possible with 1103's hardware? Also, in your 33rd post you've told it's impossible to have both 17 and 20 LTE bands, so maybe it's possible to turn off 17'th and switch on 20th band, if XT1103's hardware supports it? And one more thing-is it possible to define carrier aggreagtions(LTE-A) somehow? Thanks!
[Nexus 6  General] Azlun:
Since band 6,19 are all inside band5, so I guess possible in hardware but need to check sw setting on many radio frequency front end rx tx nv 2xxxx. Band 9 mostly part is in band3, so that is also possible. For band17 and 20, post33 is just a guessing based on Nexus5, I am still lack of nexus6 repair/service manual to confirm it. For CA, that is out of my current knowledge, I need to learn it in the coming months...
[Nexus 6  General] pernik:
Thanks Azlun for your sharing to enable LTE Band 8. I can use it in Indonesia.

But I'm still confuse when I change only nv 6828 to add LTE Band 8 and use in LTE Network, it don't have success use LTE....just still in HSDPA. And after I used your QCN, I can acsess LTE Network.

Could you sharing to us what other nv to be need change add LTE Band 8 in a device which I would like to add other device as like HTC One M7 ?
[Nexus 6  General] Azlun:
I have shared such background somewhere, key point is, each LTE band have 20-40 Rf nv items in 20xxxx - 26xxx, depend on RF front end hardware solution. Since in factory, unofficial band is not gotten calibrated, so some of rf nv will not written, we need to find the gap and patch such nv in to efs.

So, with xt1100 LTE band 8 dynamic(unique for each produced pcb board)nv 20848,20852,20853,20867,20869,20871,20883,20884,20895,20896,20896,20898,21313,and especial nv24233 values, you can make your xt1103 work on band8.

But there are some pre conditions:

1 your device own such band rf front end hardware of PAM and FEMiD for your target band according your device repair manual

2 you can find such rf front end hardware solution workable rfnv values from your phone viarrant brother devices.

3 you have right tool to filter out such nv compare and make gap qcn files to restore to phone.

Many nv tools on PC can write and read nv, but,currently,only QRCT can fullfills such purpose, I am sorry only Qualcomm can provides it.
[Nexus 6  General] pernik:
Thanks Azlun for your sharing.

Btw any link to learn or know more about nv items 20xxxx - 26xxx ?
[Nexus 6  General] 469589757:
If i need to enable XT1100 B2/B4, is it the same method like post #1 you said ? :)

[Nexus 6  General] pispuso:
Thanks for this tutorial! Thanks to it I was able to enable bands 2/4 on my XT1100 in Argentina!

Just one question though... If I backup EFS partition via TWRP now, next time I update my ROM, can I restore the EFS backup to get Bands 2 and 4 working again without having to patch the phone again?

Thanks!
[Nexus 6  General] Azlun:
Yes mostly. In fact only your flashing ROM included modem or MDM efs contents will make patched bands rf nv lost, if you just flash system and user data or boot, the nv iteems will been always kept.
[Nexus 6  General] trewaicr:
Is there any way to add B28 to the XT1103?

Hi everyone, this tutorial seems wonderfull!

I have a problem.... when i try to find the COM port in QPST Configuration, that doesn´t appear... but in Device Manager appears connected in COM26!... i try to do that in 3 diffrent PC´s with the new version 2.7 build 425, and the another one recomended by the tutorial.

At first i was worry about forgot some steps, but i do well and nothing happens!

Some guys from Argentine has been tryed to help me, but they dont know what is the problem.

Can anyone help me?

My phone is XT1100 and I want to put band 4 on it.

thank you for your time! :good:
[Nexus 6  General] Azlun:
Do you noted to removed the com26 n/a auto add port and manually add it?

Yes, i do everything like the tutorial say... and try to another thing to, like disconnect and reconnect the celphone, remove moto driver and reinstaling it, re launch the program with admin privileges, put the phone in usb debbuging on and off...

Hello, I flashed android m to my n6. Tried this to enable LTE. When I tried to activate BP tools, the required drivers doesnt appear in the device manager's list. :( It would be perfect if your work, works with android m :)

I went back to 5.1.1
[Nexus 6  General] Azlun:
if you are flashing but factory images command script, yes, I guess the new boot.img cause bp tool not works, and efs is reset while modem image is flashed. So what I have did, do this mod at android L and use multirom to add new ROM with mpz44q_sham.zip as 2nd ROM. the we can keep the modded EFS. OR, I Guess if you have a two efs backup after modded, restore it will also possible work, sorry no much time to test above idea above, just suggest you Try it yourself.
[Nexus 6  General] Azlun:
My opinion is, band 28 is an 800MHz band need a special filters. For band3 I think even you can have a place without LTE band3, but in fact such 1900MHz will full filled with 2G or 3G carriers channels which full used all over the world. So if you are expecting band39, it is far from possible.
[Nexus 6  General] Azlun:
Yes, no band40 rf front end as my guessing, if anybody can share service and repair menu, I can double confirm it from schematic.

Hey all,

Just wanted to give a warning that the version of QPST linked in OP's post contains a backdoor and a keylogger. Thankfully it was flagged by Windows Defender on installation, and there's another helpful post on XDA that explains how that QPST v422 was tampered with. If you installed QPST from the first post of this thread, I highly recommend changing your passwords and scanning your computer for malware.

Please know that I'm not saying OP's being intentionally malicious, in fact I appreciate the work put into this tutorial since I'm trying to unlock band 1 for my XT1003 just the same. Hopefully he was just caught unaware same as me, but yea, stay safe. :eek:

[Nexus 6  General] draiko913:
First off, thank you for all the hard work you've done to help the community with this information. It's greatly appreciated!

I followed the instructions with the exception of rooting and doing the backup with TWRP. Otherwise, everything ran smoothly and it appears that the value took when checking in QXDM, but even after a hard reboot and using the hidden menu to change to LTE only, I'm still not getting an LTE signal, even though I'm in an area that I have had LTE with the same sim card in another phone. Is being rooted required for this to work, or are there any other suggestions on what I might be doing wrong?

Edit: Forgot to mention, I was running M preview, but I flashed the 5.1 factory image before following the steps to enable LTE bands 2 and 4.

[IMG="Verification"]http://s3.postimg.org/9fop920wj/Update.png[/IMG]
[Nexus 6  General] Azlun:
For nexus 6, LTE only will too complex to works, it can only useful for Android 4.4 devices such as nexus 5 old images.

Another thing to check is from QPST-EFS Explorer, can you find a ./policeman folder, you can delete all files in it to try, if still fail, put a copy of carrier_policy.xml from a working phone model. If you are in Argentina, I believe somebody success even without above suggestions.
[Nexus 6  General] draiko913:
I'll give your suggestion of using QPST-EFS Explorer a try when I get home this evening. I'm actually in the USA trying to enable LTE for AT&T on bands 2 and 4. Didn't realize when I purchased my phone that it was XT1100 instead of the XT1103 model.

Hey, first of all I want to thank you guys for this tutorial. My XT1100 now works flawlessly on Band 4 here in Colombia (Movistar).

Hello Azlun,

I have accidentally purchased a XT1100 model for the US on ATT network. Doing a quick search they use other bands as well (AT&T 4G HSPA and HSPA+ use 850Mhz(Band 5) and 1900Mhz(Band 2) bands but it all depends on area if they own a license. LTE uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz), Band 4(1700/2100Mhz) currently.)

I have enabled the band 2 + 4 through this guide. However, the problem is that it only sometimes switch to LTE auto. This means I have to force to switch to LTE in the Settings > More > Cellular Data > LTE

I checked the *#*#4636#*#* settings and it says LTE/GSM Auto.

Do you know why it is not switching to LTE by itself? When I reboot phone it goes to LTE auto but it never switches back unless I reboot, or force it by going into settings. I get really good LTE when I do. Thanks for all your help!

Edit: Any way to enable Band 17 as well?

[Nexus 6  General] aoleg:
Azlun, thank you for your excellent tutorial. I used it to enable LTE bands 2 and 4 on my XT1100.

After updating the phone to Android M 6.0 (final release), I lost LTE connectivity with radio from 5.1.1. I had to flash new radio that came with the 6.0 build. I then followed all the steps in the tutorial, successfully enabling LTE bands 2 and 4; however, unlike on the old modem, the new one hardly ever switches to 4G LTE anymore (and if I force it by enabling LTE Only mode via *#*#4636#*#*, it displays zero bars, although the actual signal is sufficient for 3-4 bars).

May I ask you to please make a new file to enable bands 2 and 4 on XT1100 based on the new modem from Android 6.0? :)
