[Sony Cross-Device General] Pr3muToS:
is this working with all qualcomm processors? Or dot the device need to support it with the reciever module?!?

I want to buy nubia z9 mini, but this has not enabled LTE FDD 20 (800mhz) for european LTE usage, so it unusable for me, but i want this phone!!! xD
[Sony Cross-Device General] Product F(RED):
You can't just enable these bands on any Qualcomm based phones. They have to actually have hardware support. For example, aside from Sony devices, most manufacturers don't include North America specific bands (like AWS HSPA+/LTE) in their International variants. This isn't magic.
[Sony Cross-Device General] xda23:
Is this possible to accomplish?
[Sony Cross-Device General] Advali:
Question, do I still need to use *#*#4636#*#* to select the desired gsm/umts band (euro/USA etc) after unlocking the bands or does the phone automatically selects the available/unlocked bands to use?
[Sony Cross-Device General] palmbeach05:
Yes, you still need to do that
[Sony Cross-Device General] Advali:
That's my problem actually, I'm from south east Asia and I don't know which one to select. The options I got were euro/Japan/USA/aus/aus2/cellular/band mode 11-15. And I don't know if we use the same band as Japan including LTE
[Sony Cross-Device General] palmbeach05:
Typically i go for the gsm/cdma/lte combo option, should cover everything. That is the global option
[Sony Cross-Device General] Advali:
I don't have that option on my z3 though. I'll probably just use the euro bands since our standards are more or less the same as theirs.
[Sony Cross-Device General] Azlun:
I think [MENTION=4198062]Advali[/MENTION] means this old menu which [MENTION=4895937]palmbeach05[/MENTION] mis-understand, and I want to note in some phone model, that is an dangerous menu make your phone can lost all signals, so never change it before you have a EFS pro or twrp EFS backup.
[Sony Cross-Device General] palmbeach05:
Yes that is what i mean
[Sony Cross-Device General] Azlun:
Please note, this menu is not the drag down menu, it from top-right ... Option menu-select radio band, NEVER TOUCH ANY of Band in this menu!!

In my MOTO nexus6, if you select any item below, your signal will gone before you restore your efs. I am not sure SONY have such google bug or not...
[Sony Cross-Device General] Azlun:
According my case on nexus5 and nexus6, LTE band1/3,or band2/4 hardware is mostly there since when your phone is LTE band1/3 variant, its supports band2/4 3G WCDMA; so, you can port NOT ONLY OP's rf setting nv, BUT ALSO Rx and especially tx nv items included but not only limited in nv#24226-24229 to target phones, that can increase chance to make band 2/4 enabled.
[Sony Cross-Device General] palmbeach05:
Clarification on my end. On CM11 and earlier there's an auto-select option in that menu. I would use that. But, if i scroll down that page without getting into that menu, there's a drop down menu to select bands right above the radio off button. I standardly now use that
[Sony Cross-Device General] Advali:
Too late for that now, I already selected the EURO band. I should have read Blacksoulxxx warning on post no. 2 not to select anything. But you did say on your first reply that I need to select a band first which is incorrect. But the mistake was on my part though, I should've read other replies first just to ensure everything will work :(
[Sony Cross-Device General] Azlun:
If your phone is already out of service, To resume you phone to works, restore a efs backup is most fast; if no backup files, for nexus6 users, they reflash factory image to trigger efs rebuild from fsg partition to mdmfs1/2/3. And I recommend another method I used in nexus6 is set nv441 to all FF by QXDM or QPST also works, try to search my words about 441 in others thread...
[Sony Cross-Device General] boostnek9:
OK as I previously posted, I bought an HTC M8 from Singapore and I'm on Telus in Canada. Seems LTE isn't working , only HSPA. I've done everything in this thread and I can't make the NV values to stick on 1877, when I write to NV nothing happens. I would really like to have my phone work on the LTE band here for telus and I believe the radio already supports it, just disabled.

I would love someone to help me out and have a 25$ USD PayPal donation to someone who can help me out.. From what I read it a very much possible.

Thanks guys.
[Sony Cross-Device General] Product F(RED):
Most likely it's missing AWS LTE (Band 4) support in the hardware. It's rare that international variants contain North America-specific bands like Band 4 HSPA+/LTE. Rare, not impossible. Like a lot if Sony phones include them. Also Nexus devices.
[Sony Cross-Device General] Advali:
Thanks man, got it working now! Thanks for the advice.
[Sony Cross-Device General] boostnek9:
So how would I figure out if it does or not. This is where I'm lost.
[Sony Cross-Device General] ShiAili:
Dude. You posted your IMEI number in a public forum. You might want to pull that down.

---------- Post added at 06:30 PM ---------- Previous post was at 06:19 PM ----------

Did you try the read-write trick? In an earlier post, it was mentioned that sometimes you need to read the value first before you write to them - that is the case on my Z2 D6503.

You should also note that this is not a sure fire way to enable the bands. It depends on numerous variables. For example, while I can enable B28 on my Z2 from a hardware level, no amount of tweaking will actually make B28 work.

Telus uses B4 AWS, FYI, so that is what you need to add for LTE support. If you see it listed in your diagnostic menu and after restarts still can't get LTE service, it is likely your device doesn't have the hardware you need.
[Sony Cross-Device General] Advali:
Didn't noticed that. Noob error. Thanks for the heads up ShiAili.
[Sony Cross-Device General] Advali:
Will be flashing a new firmware but just to be clear again, I don't have to select GSM/UMTS bands afterwards right?
[Sony Cross-Device General] GeorgeZZzz:
Can anyone help me with my Mi NOTE here please
[Sony Cross-Device General] palmbeach05:
Hardware limitations due to the version you have?
[Sony Cross-Device General] GeorgeZZzz:
I have to admit it If I couldn't try more than that post...
[Sony Cross-Device General] joaquinpb:
Thank you for your work and for sharing it.

I'm trying to repeat what you did but I think I'm no "updating" the drivers cerrectly so I cant connect to QPST and/or QXDM.

Also I don't understand the exact steps you made combining the original post, palmbeach05 instrucctions and the other post you mention.

I'm in Argentina, here we use band 2 and 4 for LTE so if i'm able to apply this, I'll be able to confirm if it works.

Thank you again

D6653 Xperia Z3 - initial result

using d6653 hardware tried to enable AWS UMTS BAND 4 to work on WIND mobile in canada. followed guide, sucessfully added the bands to NV and rebooting shows the bands activated in phone info, however cannot receive any native WIND signals.... only roaming signals from other carriers... same sim plugged into my regular WIND phone works (also a Z3 but d6603 variant direct from carrier), so this mod doesn't seem to work even for SONY device which OP meant it for, and even when every variant of the Z3 is based on the same modem and qualcomm chip it just won't connect to the 1700 band 4 AWS UMTS.... this is the part i don't understand.... [MENTION=5733862]BlackSoulxxx[/MENTION]

So is it hard to unlock 3G 4G & Lte bands on my tmobile Gs6? Thanks In advance!!!
[Sony Cross-Device General] mikuru396:
I think this might be a case for hardware difference ... d6653 is the only model with TD-LTE support ....
[Sony Cross-Device General] palmbeach05:
Idk, why don't you try it instead of asking if it works
[Sony Cross-Device General] weliyt:
[MENTION=385773]oreo[/MENTION] Hey have you tried this:

When inserting the Wind sim, the Z3 will download a Wind provider profile, which overwrites all the changes to your modem and reverts back to default

So... you could insert the Wind sim, let the Z3 download the Wind profile. Your modem should now be resetted to default. Do the mod again, restart and see if that works.

The LTE difference should only affect LTE... Wind is WCDMA
[Sony Cross-Device General] oreo:
thanks i will try that when i get home, just curious though, how would you know if the wind profile gets 'downloaded' or not? is it downloaded from the SIM card? because without the reception where is it 'downloading' the profile from otherwise? when i insert the sim nothing really shows that it 'downloads' anything special
[Sony Cross-Device General] weliyt:
I'm actually doing the same thing as you are: trying to get my D6653 to work on Wind.

What I noticed is that when i insert a new SIM, the phone would pop up a message saying its going to download the new provider's settings. I'm not sure if it does for you but it does for me.

And whenever it finishes downloading, the phone reboots. Afterwards the modem settings get reverted to default (*#*#service#*#* menu)

I can't try this now since I decided to go on to Fido for the time being, urgently in need of a phone. Hopefully you could shred some light if it works (heh...then I'll switch to Wind next month if it actually does)
[Sony Cross-Device General] OB-bob:
Sooo, i have a XZR (C5502). Since it has the same Hardware (does it really?) as the Z and ZL is it possible to unlock LTE? C5502 is labeled as HSPA+ only. I read something about this modem chip and his corresponding amplifier chip, but i don't clearly understand all of it. Just want to know if it is possible to get LTE working at all.

Add 4G/LTE Band 4 or Band 4 + Band 28

Hi, I've got a Samsung S5 (SM-G900F), the original thread on samsung S5 forum was closed so I hope you can give me advice.

I read [MENTION=5733862]BlackSoulxxx[/MENTION] was able to unlock all bands on the same phone model!

I did the same to for the Band 4 + Band 28 (Decimal 134217736)

Hope you can help me.
[Sony Cross-Device General] Product F(RED):
I don't think the international variants have Band 4 antennas.
[Sony Cross-Device General] yakapa40:
@ 1989andres

with NV6828 (Decimal 134217736) you have not add B4 and B28 bands but only select B4 + B28

G900F original values are : D7 00 08 (flipped) =524 511 DEC = (B1,B2,B3,B4,B5,B7,B8 and B20) so you have B4

about B28: 700 Mhz APAC (Asia and Pacific) , so i think it's not the good band for your country and carrier if you leave at NY

if you want to know more about NV and original values you can take a look here: http://xdaforums.com/android/general/3g-lte-frequency-nv-items-qualcomm-t2950491

Do you guys know if it's possible to add the CA configs B3+B20 and B3+B7 for the Nexus 6 XT1100 version. I guess this should be possible because the Nexus 6 works in single carrier mode with b3, b7 and b20.
[Sony Cross-Device General] Pr3muToS:
i thought QPST is only for 2G / 3G?

Anybody got a version of this: http://xdaforums.com/showpost.php?p=55321005&postcount=1 , for LTE, or also for LTE?!?

3. Open the caller app and type in *#*#8778#*#* (it should go off the screen after you type in the last symbol "*"

3.5 Those on custom roms (tested on cyanogen 11 with s4 mini) can use the efs professional toolkit to change the mode to enable the diag port.(Thanks [MENTION=1140654]blackburn[/MENTION] !)

?!

3. nothing happens

3.5 .. do i need a terminal emulator now or not? got a stock rom...

i just want to try to add LTE b20 here..

[Sony Cross-Device General] 1989andres:
Hi, thanks for the information [MENTION=4583018]yakapa40[/MENTION].

I set the NV values to its original values as you recommend.

According to my carrier, they only use 4G: Band 4 (AWS, 1700*) / and later they will use Band 28 (APT700, 700 MHz**) for countryside/rural zones

I'm not understanding if why my SM-G900F is not being able to use at least Band 4, if another users have reported that they unlock almost all bands with the same model.

PS: I'm in Argentina

Service mode has this: http://screencloud.net/v/h3qY
[Sony Cross-Device General] yakapa40:
[MENTION=5802764]1989andres[/MENTION]

only in theory you can add all lte bands but in reality you have physical restrictions with the device chipset

exemple in my link with N9005: post10 .

is someone have unlock one G900F new band and tested ? i don't know , i leave in France and only use lte B1 , 7 and 20

about service mode: take a look in my link post 8 and 9 you can see all the G900F service mode .txt

[Sony Cross-Device General] Azlun:
QPST-Service Programing bands tab on nv1877 and QPST-RF Items manager mentioned in OP is really 2G/3G only.

But QPST-Software Download-Restore is something more you can change or add most nv items with right qcn files.

For LTE, Most common items are NV6828/6829,65633,24226-24229 etc... Depand on what bands and which items are lack of right value in your phones factory status, so it quite difficult for each model to have a common setting or one qcn file to set it but you can try to get success beginning on 6828/6829/65633 in case of nv 24xxx and some other RX nv in your target bands are already there.
[Sony Cross-Device General] oreo:
Final result: it doesn't work even after unlocking band.

I've gone ahead and tried all methods including first flashing to WIND firmware and baseband (d6603) then unlocking Band 4, again same thing unlocked band shows in service info but it will not connect to that band even with when modified with 6603 firmware and modem. Really sad now cuz I was depending on it to work since i had bought the limited purple edition of the 6653 and now it is an expensive piece of metal... And I'm not gonna switch to the robbers networks to pay that extra money for compatible LTE

Upon more investigation seems like this is true for other devices as well looked on other device forums and not a single one has ever confirmed a so called " unlocked " band is actually usabl. Including throughout this 113 page thread... Every " confirmed" case was merely the words that's showing in service info, but none can confirm actually connecting to that band due to them not actually having access to those bands. But other threads have ppl reporting same thing as me where unlocked bands still don't connect... So this all seems just a cosmetic change and not a functional change at all...

Im looking into buying an Xperia Z1(L39t), Z2(l50t), or Z3(L55t). These are the chinese versions, so I want to flash with an english ROM, but I would lose my TD-SCDMA.

Can someone confirm TD-SCDMA unlocked with english ROMs on any of these models, please?

Won't work. Similar to my case. See my posts. The hardware won't let it work still.
[Sony Cross-Device General] eldonly:
why do you want an english rom?

you wish to upgrade to lollipop?

if your radio/antenna support that frequency, then i guess you can get it with baseband unlocked.

you can have a try. worst case you flash back the chinese rom to get tds back.
[Sony Cross-Device General] 3clipse:
Chinese Android build does not include gapps

and certain features are disabled.

I think your case is different. We dont actually know if the D6653 has the modulation hardware to run band 4 regardless of the Qualcomm chip.

In my case, I already know the bands work. I need to know if other ROMs will recognize them.

I want to comment some nv items you may not awake at enough. For band4, nv24198,24202,24229 may be missed in un-support model, you need to copy it from support model to try, tool is dfs or qpst. Surely if you are qcom customer, qrct filtering in XML and qpst for exported qcn restoring is best way.

boost bands

I have a Samsung Galaxy Rush for Boost mobile (Qualcomm). Samsung.com says it only has 1900mhz band. So I need to know if that is a software limitation, or a hardware one? If it's software, then I will follow the instructions on this thread to try and unlock the 850mhz band to flash to Verizon. But I don't want to go through all that if it is a hardware limitation, because it would be a big waste of time. Can anyone advise me?
[Sony Cross-Device General] palmbeach05:
Yes. You see that post right above yours? Read it.
[Sony Cross-Device General] supermaxkato:
Palmbeach05, let me ask my question differently. How do you determine which limitations are software, and which are hardware? If you don't know, then no need to reply. Because you wouldnt advise someone who only has a CDMA antenna to attempt a software change inorder to enable GSM; it would not work and be a frustrating waste of time. So another way to ask: do all CDMA phones have all CDMA bands naitively (and carriers lock the ones they don't want)? Or are different CDMA antennas created with certain bands only?
[Sony Cross-Device General] noahvt:
I did this to my C6903 running stock lollipop, I unlocked all GSM and WCDMA bands and I can see the changes when going to the service menu but I have 2 small issues:

1: Can't get more than 2 signal bars on LTE and H+ when using Edge I have 4 sometimes I have no service at all

2: I do not have the select gsm/utms option like [MENTION=5733862]BlackSoulxxx[/MENTION] does (removed from lollipop?)
[Sony Cross-Device General] palmbeach05:
The internet is your best resource for researching your device's chipset specs my friend. Even if you don't do the research, unlocking a few more CDMA bands won't hurt. And, as a GSM user, i have, just for sh*ts and giggles, unlocked the CDMA bands on my device. No issues were experienced, even if unlocking the CDMA bands was a waste of time. But the program used in this process tells you what bands are CDMA. So just try it out. It takes not even 5 mins to do, and we're discussing this for going on what, a day and a half or something. You could have had your answers already.
[Sony Cross-Device General] Azlun:
I think both your view are right, in some parts of angles. I want to share.

In fact bands aspects are something about rf front end hardwares about Tx PA modules and Rx filters FEMid modules. Outside chipsets MSM89xx and WTR16xxL.

Such hardware solution is not enough to transmit and receive right wireless signals, what we need is arrays of offsets and factors parameters in sw setting called rf nv items. So, in cases you are targeting to a band in side your rf front end HW, then you need a right SW rf nvs in EFS, and even a right modem sw image to support more high level protocols for multi mode X multi band operations.

So, palmbeach05 is right because he believe keep trying is will prove the rf front end hardware capability, but some awareness about such HW limitations is need. And supermaxkato also right since he was trying to find out what is HW AND SW theory to guide the trying in minimum effort, I want to said, if we have a same PCB and same rf front end hardware as reference, for example, band 2 rf nv item values from D820 for D821 enable band 2, them, that will take you one or two days to do it, if there is no such reference, we need luck.. Luck like SONY devices, the target band rf nv items default values are all pre set in each variants models and Sony uses unified same PAM and FEMiD in them.

There also no luck case, for most SAMSUNG devices you will much limited since most their device rf front end hardware is just 4-7 bands for hardware cost controlling. And they do not have enough time to develop and test good default vaules for each PCBA designs.

So they only forcus on customer target bands.
