I just got a D6603. I'm on T-Mobile and I wanted the phone to be rootable so I got the unlocked version instead of the branded D6616. However, the D6603 doesn't have LTE band 12 support, which means my signal at my desk at work is weak and frequently goes out altogether.
I found this guide on unlocking all LTE bands for a phone with a qualcomm processor. I was wondering if this is actually possible for the D6603 (i.e. band 12 is just blocked by the firmware) or if the D6603 lacks a certain radio necessary for communicating with band 12 towers. Has anyone tried this, or any other similar hack, for enabling a certain band or frequency on a phone that doesn't normally support it?

Check this to see which baseband exactly is you want to unlock and if your device supports that baseband. If the radio is missing, it would be impossible to unlock it. However if it is just the software, maybe following the guide help.
See attachment for your reference.
Or just wait for lollipop update. Just came across it

Hi All,
The issue with my Verizon M8 [the rare LRA (LTE for Rural America) subvariant] is that no matter what firmware version/RUU I use, I only get GSM connectivity on it. No WCDMA or LTE. I have checked the WCDMA bands in my country and that is not an issue. When I select WCDMA only option, I cannot get any signal. I have flashed the all the LRA (*.**.512.*) RUUs as well as all the Verizon (*.**.605.*) RUUs but no luck at all. If this issue might be related to PRL settings then please let me know if any of you have any idea. I have also checked the relevant WCDMA/LTE bands via CDMA tool and they are also enabled.
My M8 is currently S-off and has Super CID. I am using it outside the US on GSM network.
This has got me very frustrating and I need to find out if this is a software issue or a hardware issue. One more thing is that another guy here has exactly the same variant as mine. He bricked his radio by flashing the GSM firmware. I provided him my phone's relevant partition dumps and after flashing those onto his phone, his phone's radio became operational but now he has the same issue as mine. So I think that this issue might not be hardware related.
Any help on this will be greatly appreciated!!
Same problem
Anyone can provide any help on this??

do you know the actual bands/frequency the gsm network uses where you are? the prl is going to be pulled from your sim card. have you also tried a diff sim card?

Hello. Yes, I know the bands used by 2G, 3G and 4G in my country. And yes I have switched sim cards even from different networks. The PRL version shows as 00000 when i look at it from the settings. I have even tried to update the PRL from a prl file provided by a xda user in some other thread but still it shows as 00000. I have seen some threads and ppl had this problem with One S. Though some of them were able to correct it by flashing some stock and custom radios.

odd. i wonder if that lra model is sim locked like the sprint variant. is it also acknowledging you have a sim card inserted when you check in about phone? as in, does it display the sim #

Well, I thought too that it might be sim locked but then why it is working with 2G networks. There should be no signal at all then. Also these LRA variants are being sold by many online retailers including Amazon as sim unlocked phones. And yes it acknowledges when I insert or change a sim. Says "Preparing sim card" and then I get a signal (2G only). When I choose 3G only in network settings, the signal is gone immediately and I have to switch back to auto or 2G only to get the signal back.

So then list the specific band numbers for 2G, 3G, and LTE for your carrier. That is really what the previous response was asking.

900/1800MHz for 2G
2100MHz for 3G
850/1800MHz for 4G/LTE

This is strange, as the 3G band 2100 Mhz is really common (many countries use it for 3G, and most any recent US phone intended for foreign travel will support it), and should be supported by the device out-of-the-box. This tells me the problem is likely not RUU/firmware related.
You sure the APN is properly typed? And does your carrier use any different APN for 3G, LTE, etc.?

No it uses the same APN for all types and its configured correctly. I also thought the issue might rather be related to some NV values or PRL. If I set it to 3G only, it "Sees" the carrier as I can see a signal bar in network signal guru app, but the mobile is not able to connect to it.
so i am thinking that since this is a lra variant, a lot of bands may be disabled. have you seen anywhere else that someone got a lra variant to work outside the us? i know you said people were selling it as being unlocked, but maybe its not

Well the LRA variant is practically the Verizon one with everything same as the Verizon variant. There a lot of links on both Amazon and eBay in which its mentioned that its LRA variant and is factory unlocked and can be used anywhere in the world. And yes I came across various threads on XDA in which people had this same variant, working fine (3G atleast) but they wanted to upgrade to Android 6 MM as there is no official update available for this variant after Android 5 Lollipop. As for the relevant bands (2100MHz for 3G used in my country), they were already unlocked (checked via CDMA Tool and QXDM).

hmm this is quite the problem. if you can confirm you are using the same rom as the others, i would then think the issue is the radio being defective

I am using the stock LRA RUU (android 5.0.2). I have also tried the VZW RUUs from 4.4 to 6.0 but the same issue exists on them all. Even I have used GPE and Sense based custom roms but the same issue. I think that the issue might be related to some NV values or this phone might be network locked. Is there a way to check if the phone is network/sim locked? As I am getting the (2G) signals for all the networks in my country.

it being sim/network locked makes sense, because the phone was made for people who live in the middle of nowhere. there would also be a high probability that none of those people will ever travel outside the country. i do not know anything about the nv values and tweaking them, but i have looked at that thread a few times. lastly, if you have only picked up 2g regardless of sim or apn used, it could be defective radios

yes I got my issue fixed. Can u confirm which device you have? software version *.*.512* or *.*.605.*?
From what I have read here, it looks like T-Mobile support for the OnePlus 6 today is very good. Band 71 is supported, as well as Wi-Fi Calling and VoLTE.
I've read about the lack of certification for Verizon and Sprint networks currently, but apparently the OnePlus 6 has CDMA support.
Of course it is just speculation at this point, but does anyone know of any reason why the OnePlus 6 would be unable to operate on the post-merger T-Mobile+Sprint network? I'm assuming if I buy a OnePlus 6 now, the merger would take place during the lifetime of the phone.
Yeah. But it would be probably years before everything merge together by then this phone would be out dated

The CDMA "support" is bands BC0 and BC1. There is no bands for US carriers. This will only work on CDMA networks in other countries if I understand this properly. I'm not totally sure about how the radios work but the OP5 didn't have the antennas included to add band 71 support for T-Mobile even though the modem itself had support for it. So, I'm not sure if support for the correct bands can be added in an update.
Hi I recently purchased the GM1910 model which is the Chinese model and it's on its way in the mail right now was curious about if it was possible to add Band 71 to the phone. I plan on rooting and using a custom rom already. I have TMobile which I know uses the Band 71. Would just flashing NA build add it or is there more to it.
I'm curious to find out this as well

From what I heard I don't know for sure. But people said the hardware itself is different. So I don't know if you can just flash it.
Your correct, it's hardware and new radio bands can't be added...
I've heard that the phones are identical. They are only switched off bands. Older OnePlus phones were able to unlock extra bands that were locked based on the region. The band support hardware wise is built into the modem. They are disabled by software.
Obviously they have to have antennas for the radio frequencies, but the hardware seems to be the same amongst gm1910 and gm1917. I wonder if someone posed a modem backup from a gm1917 and you flashed on a gm1910 it change the modem firmware to the US.
I'm willing to try this if someone posts the .zip from a gm1917
I want to unlock bands 46 and 48 for Verizon since it's LAA and CBRS/3.5ghz LTE

Hell I'll risk it to :highfive:
I wonder if something like this would work? https://forums.oneplus.com/threads/guide-unlock-aditional-bands-for-qualcomm-devices-oneplus-one-edition.193610/ But I can't seem to get the drivers to work correctly.
does anyone know if the 5g bands are limited by the hardware or software? do i need an in2015/in2025 to work on tmobile or could i get any version and flash it to the proper region?
It's is hardware based and software enabled. One thing doesn't work without the other.
its good but depending on area and if you have root 5gnr isn't enabled at first i had to switch 2g/3g/4g only to make network work stable after i rooted changed database file changed few others network 5g is 5x faster then stock im on global with T-Mobile modem flashed
Best to get that 2015 or the T-Mobile variant. The rest would probably work to some degree, but they'll be missing important bands.
