[GUIDE][PARTIAL] Unlock Additional LTE bands on Chinese & US variants of OnePlus 3

[otonieru]

Ok
So first I will apply patch
Root is necessary?

Patch can be applied through TWRP

Root is needed to enable diag port, you can use snowwolf apk for that as well,

Please,

Read again the main post. Anything was described there.

Hello to all colleagues, I have less than 24 hrs with the OP3 and I have almost 3 hours reading everything and trying to download the necessary
But I definitely need help to guide me, to begin with I have OOS 4.1.3, model A3000 and I need the band 4 for the LTE to work in my country, But I'm not sure what version of OP3 I have, I have 2 imei so it's not the Chinese version that I read that only has an imei, I already have the bootloader unlocked, twrp installed and rooted with magisk

Attachment screenshot of info showing network signal guru

Try to follow the tutorial but I can not install the drivers correctly on the port diag, and without that I can not follow, and disable the protection of installation of unsigned drivers of win10

If it is possible to enable a band, does it work even after rebooting the cell? Or after a hard reset or even flashing a rom? I hope someone can help me, and believe me, I already read and read but I need help

Greetings and thanks in advance

Very first page of this thread. Step number 5. Has the link you need. Download the app. No driver required once you use the app (at least for me).

Hahaha if you notice it, thanks for your help friend!

Excellent the apk to simplify everything, but I found a problem that I can not solve, I can not install the QXDM, My laptop uses windows 10 and it gives me the error of internet explorer 6... Any suggestions???

Edit 2: Problem overcome, I simply had to find the correct version that works with windows 10

I was able to follow all the steps, but I can not unlock the band 4 that is the one I need, I do not know that QCN is the one that I should flash my A3000 CN to be able to unlock the band 4, any help?

sadly B4 is untested and unproofen, since no active dev (me, baska & snowwolf) of this thread has that band in our country

thus doesnt matter what we tried, we cant really test & debug it realtime

in a normal methodology, what u need is flashing US based QCN (USMODELNOIMEINEW.qcn) followed by the fbrx of US (fbrx_us.qcn) model as well. And finish it by changing the NV 1878 to 232

but no one has much luck with B4 & B12 so far

I understand ... and precisely those files are the ones I use ... I will have to sell it and buy a US version

Oneplus 3T US managed to get B3

Hi, I followed the procedure and managed to get B3 and LTE on a US 3T. However after a while on LTE the phone looses LTE and changes to H+. After reboot I get LTE again only to loose after a while.
Any solution to this issue?
Thanks in advance.

Anyone knows how to enable TDD-lte bands like 39 and 40 on US model? Been trying that for a few hours still nothing. I tried a lot of combinations, still no luck of getting any sort of lte signal

Unlock band 2,4,12 on UE OP3T

Hi everybody,

In August I'll be in the US, and I want to use the 2nd sim feature for a Tmobile sim.

Is there a way to unlock LTE band 2,4, and 12 on OP3T EU?
Or change the frequencies from EU to US till I'll be in the US?

Thanks.

Hi everyone,

am sorry to say that, am no longer having my Oneplus 3 since months back

decided to sell it to my colleague, since he need a good phone more than me,

thus, i will no longer able to test anything related to this unlocking mod,

this thread will remain open though,

other dev and users still can discuss here, and helping each other,

it just you might not see any new updates/progress from me anymore,

thank you for having me in Oneplus 3 forum,

Salam dari Indonesia :victory:

You're welcome to try but this was made with all OnePlus 3 devices in mind. The rmt storage latch especially. Always back up efs in TWRP

Hi everyone
If i will update the software the patch will sty?
Does anyone try to update to 4.1.6?

Its working on 4.1.6... but you will need to re-flash your additional bands again after you update...

 

[otonieru]

Hi everyone

Most important think is to reflash the storage patch.

Quick way to regain the unlock is :

1. Backup EFS
2. Flash 4.1.6
3. Reflash Rmt Patch for 4.1.x
4. Restore EFS
