if you have add Band Class in NV1877 and you want CDMA/EvDo menu

with a root phone and an explorer (root browser)

go to system.build.prop

and change : telephony.lteOnCdmaDevice=0 to telephony.lteOnCdmaDevice=1

[Android General] yakapa40:

N910T: by default NV6828 is DF 08 01 00 00 00 (B1,2,3,4,5,7,8,12,17)

i have not this device but if you are with lollipop you must in first downgrade to Kit-Kat for diag mode

[Android General] ljwnow:
[MENTION=4583018]yakapa40[/MENTION], thanks. I was able to make the value stick and I'm on lollipop. I will let you know the value soon. May I ask why we need KitKat ROM? Thank you.
[Android General] AlpineMan:
[MENTION=4583018]yakapa40[/MENTION] if you're in lollipop and you want to enable diag mode, power down your phone, remove battery, boot up your phone in recovery mode (assuming you still have the stock recovery), then enable CP Logging. Phone will reboot, and then you can turn on diag mode.
[Android General] ljwnow:
[MENTION=1130160]AlpineMan[/MENTION] and [MENTION=4583018]yakapa40[/MENTION] I calculated the value to be DF08 0100 E001 in order to enable B38 B39 B40 and B41. I am not able to test it now. The value was able to stick but service mode does not show that B38 39 40 and 41 are enabled. Is that normal? Is there any other way I could check whether the bands are enabled successfully?
[Android General] AlpineMan:
You can install the latest version of DFS (demo version). It will show you what LTE bands are enabled. Thing is, even though it may say those bands are enabled, it doesn't mean that indeed those bands are present and usable in your phone. Point is... You can enable LTE bands on your phone even if those bands don't exist on your phone.

[MENTION=1130160]AlpineMan[/MENTION]: Were you able to get those extra items that [MENTION=4583018]yakapa40[/MENTION] has in your phone?
[Android General] AlpineMan:
I have not been able to verify that the extra bands I enabled are actually working.

Another user in this thread, I think it's [MENTION=5256159]Azlun[/MENTION] mentioned that in addition to enabling those bands, I'd have to add additional NV Items...which I have not done.

In addition, I don't know if there are other LTE bands in our area that I can connect to.
[Android General] idoit:
Ok, but have you been able to get WCDMA/EVDO/... in your list?
[Android General] AlpineMan:
WCDMA and EVDO are enabled in our Verizon Samsung phones already by default even before I started experimenting with this. I can connect on Sprint's EVDO and AT&T & Tmobile's H and H+.

The challenge for me is finding out whether the additional LTE bands I added is working. I can only verify at this time that I'm able to connect to AT&T and TMobile via LTE band 4...but this band is already enabled in our phones by default. I don't know whether the areas I've visited have other bands. I always connect at band 4, H, or H+ only.

Alright, a very strange thing happened last night. I wanted to try again to root my Mega with KingRoot which didn't happen unfortunately, and phone restarted. When phone came up, SIM card showed No service... I was so angry with the team who made the root method, and I didn't have service for whole day. I was very close to do factory reset next night in a hurried way to get my phone's main functionality back (yes I use phone for calling :D) But then, I fell sleep which I'm glad for. In the morning, I went to mobile network types and weirdly I saw there are 4 options instead of 3!!! I used to have 1. GSM only, 2. WCDMA/GSM (auto connect) and 3. LTE/WCDMA/GSM (auto connect), but now there is another option 4. WCDMA only !!!

I tried to change it to all old three options but it stills showed No service! Then I chose WCDMA only option and in a few second, service came back!!! I restarted the phone and it's all functional. I still have 4 options NOT 3 options that I had. This phone is untouched NO ROOT at all (so I haven't modified build.prop file). I am wondering why? What happened?!!! This is a GSM phone not WCDMA phone! I am baffled. O_o

[Android General] AlpineMan:
[MENTION=5256159]Azlun[/MENTION] the more I've researched the topic, the more I come to the conclusion that you were right all along. For the phones that I've tried to enable LTE bands (SM-N900V, SM-G900V, SM-N910V, SM-N915V), it doesn't appear that simply modifying NV Items 6828 and 6829 is enough to enable additional LTE bands. Additional NV Items must be modified and/or created like in the example you've shown above. My question is, are those the only NV Items that need to be modified/created to enable LTE bands 1/2/3/4/5/7/8/13/17? Perhaps even looking to extend this a bit to LTE bands 1/2/3/4/5/7/8/12/13/17/20/29.

Thanks.
[Android General] botwa2000:
I can second that.

I've been trying to add an LTE band B20 to my SM-G906K (see my thread here http://xdaforums.com/showthread.php?t=2948822) by modifying NV 6828 & 6829 trying numerous options (ie adding the band, replacing one of existing bands, etc.).

It's either additional NV values need to be added/edited or there's a hardware limitation/restriction that doesn't allow using B20 on my device.
[Android General] AlpineMan:
I just purchased an SM-N910T. This phone has the LTE bands I need. Perhaps it will give me a clue on what additional NV Items I'll need to enable additional LTE bands on my other phones. It should get here sometime this week.
[Android General] AlpineMan:
The T-Mobile Samsung Galaxy Note 4 (SM-N910T) just arrived. Here are its default NV Item values.
[Android General] AlpineMan:
I also just received the AT&T Samsung Galaxy Note 4 (SM-N910A). Here are its default values. This phone is very similar to the T-Mobile version.

I think these 2 phones can easily enable additional LTE bands by simply editing NV Item 1877 & 6828 unlike the Verizon model.
[Android General] botwa2000:
Totally keen to hear back from you once you try your theory.

Though as we said you don't see ALL the NV items, just those visible via QXDM

Btw you can export all the NV items with EFS Pro into csv file and easily compare in e.g. Excel
[Android General] AlpineMan:
Good idea. I'll do it this weekend if time permits.
[Android General] Azlun:
Sorry missed your post for weeks. You have right direction being awake that there is more NV to change, but I am not sure you can reach your target, since just fail with my way on s5 SM-G9008V for band8.

Anyway I encourage you to have a try with luck and me. You also are right there is not only NV 24xxx ...v3.. NV to make a new LTE band enabled, there are almost 36 NV for each LTE band, only among of simular RF front end hardware variants that with same WTR, PAM,and FEMiD,and RF PCB layouts, then it makes sense to porting NV values directly with 40% success chance i guess.The policy are: 1. porting only the band NV you are target to, no touch other band RF NV. 2.such 36 NVs, IDs are from 6596 to 26999 depends on different target band, there around half of them are static NV, same values in all varriant, this part no need to modify, some you narrow down to the NV I have changed on XT1103 B1 XT1100 band2/4,D820 band3 and D821 band2/4

3. You may dig more in EFS Professional, which I am not familiar with, to find a way to import qcn file and edit them to compare and porting NV values in above ranges, for each target band ,like I did on oem tool QDART-QRCT-NV Manager which I am not allow to share.

4. After porting such kind of NV, if still fail, two more directions I still not yet try with potential, first is Samsung Android system.img have more limitation than AOSP or Google Edition Android, replace it may bring more breakthrough, and modem image since 5.0 have more limitation, so Android 4.4 modem is preferred if your have choice.

Secondary, in case of your target device WTR is different from XT1103/XT1100 WTR1625L and D820/D821 WTR1605L, or just owns a different modem sw baseline, that means my NV items changed may be not enough, we need to find further more NV to go even based on such 4 devices are success, that need to filter from NV names band by band, and compare each items vaules to filter more new items to try.

---------- Post added at 08:02 AM ---------- Previous post was at 07:52 AM ----------

Can you Send me 910t and 910a qcn backuped from QPST Software Download? I may help on filters them into each band before compare...

---------- Post added at 08:09 AM ---------- Previous post was at 08:02 AM ----------

Band20 will have bigger chanllege that band2, because lower band such in 800mhz mostly need a dedicated PAM/FEMid filters, then there will hardware limitation in many case, you also have luck the hareware is including this band, more info and a qcn here http://xdaforums.com/showthread.php?p=60046406

[Android General] yakapa40:
yes rooting or downloading a new firmware can change some NV values

exemple with the CSC in the product code
[Android General] idoit:
Oh, I was about to restore my NV to the backup I had prior to booting! So that's a bad idea right? I shouldn't do as it's dangerous?!

Also, what do you mean by "exemple with the CSC in the product code"?

EDIT: To be exact, there are 28 changes made to my NV! Weird, as I didn't do anything like new firmware or ... just rooted. O_o
[Android General] yakapa40:
the product code is store somewhere between NV10000 and NV10400 ( non authorized to change it ) .

if your original product code is SM-G900FZBA

XEF

and you flash a new firmware with ITV CSC , your new product code will be SM-G900FZBA

ITV

so flashing a new firmware have changed a NV item value

[Android General] optimustest:
hi, I'm in same jkjambo's situation but with an LG Optimus 3FQ (Tmobile). No 3g in Europe even if there were already the good values in my phone:

NV1877 bit7,8,9,19,21,22,23,25,26 = 06 E8 03 80 = 80 03 E8 06 (flipped)

441: 00 FF FF 00 00 00 00 00

946: 00 FF BF 00 00 00 00 00

2954: 00 FF FF FF FF 00 00 00

I can write succesfully the NV and they are persistant after reboot, for example if I put zeroes in 441 , after reboot i loose radio signal at all as expected.

So why with the good NV values i don't have 3g? what i am missing? any suggestion please?

What a lot of people don't realize, is that you can change the NV value to pretty much anything, BUT if the hardware doesn't support it naively, then it simply won't work and just gonna waste a bunch of time trying.

When they went to order it for me, their system wouldn't take the coupon and they told me coupon could only be used in the store. I reminded them that we were in the store having this conversation. The manager ended up "taking care of it", and knocked $50 off of the price.
