NEXUS 6 US MOTO XT1103 Band1 Enablement Tutorials
Foreword:
With the US version NEXUS6 XT1103 Chinese users, most of them come for China Telecom
, but is there such a telecommunications in many indoor shopping centers and car parks, do 4G LTE band1 2100MHz coverage, but also greater bandwidth than band3 15MHz with 20MHz bandwidth with China Telecom license.
What is a pity, XT1103 band1 RF front-end is shipped out without factory calibration, so only official usage is [email protected] only for China Telecom.In fact, as NEXUS5 band3 enablement, NEXUS6 RF front-end hardware also left a tiny space to enable it. The following tutorial is the first edition, With more extensive testing,It will needs correction on your demands.
I am sorry I do not have English version computer to reworks the Chinese screen captures,
I believe you have some way to understand around.​

STEP1: using TWRP backup EFS
you can nexus6 of TWRP-Backup-EFS. More insurance after the phone Root, you canalso EFS Professional to backup your original EFS.

FINALLY: Check Whether Band1 Enablement successful methods
Method 1: Insert China telecom USIM cards, confirming a place where band1 with LTE Cell ID can be found with the end of HEX is 00,01,02,03,04,05 of LTE base stations (in the dial-up interface, enter * # * # 4636 # * # *, open "mobile phone information ", the" Set preferred network type "to LET ONLY, and then find the" Location: LAC = 7101 CID = 1924c01 "in this column, the CELL ID is inside this CID.
3.1.png
Method 2: Use the LTE Discovery watch band states.
NOTE: These two methods are there GCI (CID) guessing band, is only applicable to some of operators such as China Telecom, the absence of good planning China Unicom 4G CellID, and also China Mobile is not applicable for this .
[email protected], we have LTE Discovery update to 3.19, support NEXUS6 display the real MODEM LTE Band!! thanks for Danial and his great team!!

While you want to Check real band PC tool QXDM may help if you have such tool, menu path is View-LTE- RRC layer-RRC/NAS Status Screen- Frequency band, wait for 10mintues for update or use airplane mode on/off to Tigger update.
In case you are not in LTE covered area, but just want to check the qcn is applied or not, reset your phone in boot loader mode, select BP TOOLS again,them use QXDM-view-NV Browser-Item 06828- read to get the value, it should be 1099830466655 for add band1 while stock default is 1099830466654,
Other qcn XT1103 add:
B1/8 1099830466783
B1/9/19 1099830729055

Could you send the xt1100'qcn to me? Q2954103426 . If I retore xt1100's qcn to xt1103, it only can make xt1103 support band same as xt1100?

No, you can not enable all the band but some, and it need some technical filtering job,
RF front end hardware is arm and body of RF driver software soul.
I will try to bring band8, but need more weeks to find time gap during my work.

Hi, I messed up my NV values and I can't get signal anymore. Can you please post original XT1103 QCN file so we can restore the backup? Thanks. :eek:
Please note the normal QPST-Software Download backup qcn will not works for restoring,
and older QPST-RF NV Item manager backuped Qcn can not cover all RF nv now, so it is also not good choice for you to restore Solutions for your issue,
Soution1. In case you only lost your signal after you use 4636-Phone Info-Select UMTS band- US band, Try to set NV00441 to 0xFFFF with this qcn, by QPST-Software Download, an old post is here:
http://forum.xda-developers.com/nexus-6/help/help-locked-nexus-to-usa-band-t2975290/page2
Solution2. for others failture reason, To NEXUS6 reflash the factory images will help to reset all your nv from backup eMMC partition,

Thanks! Is fastboot flash radio enough to restore everything to normal? :laugh:

edit: looks like you have to reflash everything. Oh well.

---------- Post added at 06:28 AM ---------- Previous post was at 06:14 AM ----------

I restored the factory image and it's fine. There's a bug with the current factory image where it doesn't flash system and userdata when you run flash-all.sh, but it seems to have flashed the nv value backup without that. I didn't reflash system and userdata manually so I get to keep my phone without wiping.

Any idea why line 6828 in NV browser says 268501086 in my XT1103? According to LTE band calculator, this means the phone supports band 2/3/4/5/7/17/29. But Google Play says the phone supports 2/3/4/5/7/12/13/17/25/26/29/41. Any idea why this supports seemingly less bands?

Looks like some Moto X have this band configuration, but my Nexus 6 shouldn't. Can someone confirm their stock line 6828?

  1. Will this change stick even after a firmware upgrade, say, after upgrading to Lollipop 5.1?
  2. Is this technique applicable to a D820 Nexus 5 as well?

1: Is fastboot flash radio enough to restore everything to normal?
Az:I never try, may be you can try when you have enough partition backuped.
2. for nv6828, the stock default is 1099830466654
and after my qcn written, it should be changed to 1099830466655 (add band1)
in fact there is many other nv added and overrided, so a EFS backup before qcn write in is suggested.
I can not understand why your value become an unknow one.

<!-- Add Band1 in LTE bands over XT1103
default 1099830466654 decially = binary:
00000000 00000000 00000001 00000000 00010011 00000001 00011000 01011110B
(band 41 29/26/25 17 13/12 7/5/4/3/2 )

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://forum.xda-developers.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 :(

Anyone know how to get the SPC/MSL code if it's not all zeros? My N6 is Amazon sprint version but I'm using it out of 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,
Sam.

    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.

    I just ran this process with QPST 2.7 Build 425. I am on an XT1103 in Switzerland for vacation and was not able to get Band 20 to work. The phone supports ALL the other bands that are used for LTE, but apparently the area that I am in on Swisscom is using 20. I flashed the file that says it has 20 in it, but I did see some notes from Azlan that he wasn't sure that 20 would work due to some kind of overlap with 17 that is already supported on the XT1103. Azlan, if you have anything you want me to try while i'm here, I'm in Switzerland/France for the next 7 days.

    Thanks for all your work on this, I'm sure most of the people that are successful don't ever come back and say thanks, just like everyone who posts ROMs, myself included. Thanks for what you do for the community.

    Hi, I messed up my NV values and I can't get signal anymore. Can you please post original XT1103 QCN file so we can restore the backup? Thanks. :eek:
    Please note the normal QPST-Software Download backup qcn will not works for restoring,
    and older QPST-RF NV Item manager backuped Qcn can not cover all RF nv now, so it is also not good choice for you to restore Solutions for your issue,
    Soution1. In case you only lost your signal after you use 4636-Phone Info-Select UMTS band- US band, Try to set NV00441 to 0xFFFF with this qcn, by QPST-Software Download, an old post is here:

    Solution2. for others failture reason, To NEXUS6 reflash the factory images will help to reset all your nv from backup eMMC partition,
