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

[pprajaa]

Lol, guys more questions without reading please.

My questions was regarding 3t

My questions was regarding 3t

procedure should be the same, drivers will work but you need to edit them since the 3t is a different phone (get your phones hw id from hardware list in windows when your op3t is in diag mode and paste it in the ini file of the driver)

then only issue i see is the patched rmt_storage that might not be the same in the 3t.

Do a nandroid and flash it to see, maybe it works, otherwise you'll need to patch the static_nvbk on your own, because no one has done it for the 3t yet ?

But yeah, band unlocking works for some bands but not without downsides like someone already said... it's pretty sketchy right now but will eventually get better ! (atleast i hope lol)

Has anyone tried to do a side by side hex comparison with 2 qcn files from 2 differ t devices with the same model? (e.g 2 us versions) to see if there is any differences they can pick out which may help find the missing part to this puzzle to unlock bands and keep your own Imei number

Stuck

Hi. I'm new here. Sorry if I break any rules. Btw, I'm stuck at step number 6. How do I install the Qualcomm Diag Driver? There don't seem to be any installation file inside the zip. Please help.

So OnePlus releases the nugat kernel for 3/3t this is helping with something?

Kernel doesnt manage radio, it's to high level

I have one plus 3 US version,
Can I use A3000CN base to unlock all TDSCDMA&TD-LTE band?

I have a trip to china next month, it would be great to have all China bands if possible.

If you don't use CMCC in China, the TDSCDMA and TD-Lte support isn't important
In China most cellular use FDD-Lte Band 3 as their main band, and use Band 1 as the second band.
But CMCC only use TD-Lte, and you will seldom find TDSCDMA in China.

I have a A3000 CN and I tried to follow this procedure but it's unsuccessful. First I have a problem with QPST reading the phone's port - it worked if I input the com port manually, then it reads the phone and it looks like it writes the qcn correctly but then in 23 I only get the A3000 bands. I ticked all the A3003 bands, written them and now in Network Signal Guru I can see them all, but I constantly lose signal (in the middle of a 600K city) and that didn't happen before. Someone encountered this? Also did someone succesfully enabled band 20? Maybe the problem lies in my PC (win 7x64) or the system on my phone (Nougat)?

There's no method for band 20 right now @baskaflyfer is trying to unlock it and has promising results.

 

[Toldo]

Yeah, but other A3003 band doesn't work also. What's more interesting, after efs restore, guru still shows the band that I tried to add (the reception got back to normal tough).

What band are you trying to unlock ?
Happens to me too in nsg, just press the clear button and the correct bands will apear

 

[Toldo]

Well, what I would love to have is to make A3000 into an A3003. In my country, most providers use band 3 in suburban areas, and band 20 in less urbanized areas. So in cities I get LTE with no problem but outside I get mostly H+ which is still satisfying for most uses but... LTE would be much more comfortable.

For band 20 you will need to wait

Hi everybody. It's all for testing.
I'm sorry it took so long. I was a little busy.
1. Here are archives which include separate QCNs for each LTE Bands from those versions of the phones:
A3000_cn
A3000_us
A3003_eu
A3010_cn_3T
2. Use QXDM and NV Calculator for unlocking LTE Bands, if it needed.
3. Here are archives which include one QCN with frbx_cal for the seven working modes with values from those versions of the phones:
A3000_cn
A3000_us
A3003_eu
A3010_cn_3T
4. The most important thing that you need to do is to change the value in id1878, it's hardware config, in QXDM.
I know 7 working modes:
225 - ???
226 - A3003eu
228 - ???
229 - ???
231 - A3000cn
232 - A3000us
237 - A3010cn
5. It's patched_rmt_storage, tested on A3000cn OOS 4.0.1
I know that it will work on A3010cn_3T Marshmallow, but, just in case, copy rmt_storage from the phone on the PC (path: root/system/bin)
and if you will have a problem after flashing patched_rmt_storage via TWRP, just replace your rmt_storage in archive, don't extract, only replace!!! And flash it again via TWRP.

Anybody can share the backup QCN from 3T_eu and 3T_us, please in PM???

And about B20 i still didn't test nothing. I have almost no free time
And sorry for English

 

[Toldo]

So how do we proceed?

 

[Stupifier]

So how do we proceed?

My recommendation......wait around and follow the thread until others with more time and expertise can figure it out. Hopefully, an updated Guide will follow.

Thanks @baskaflyfer

So i confuse what use of file at point 1 and 3?
Point 4 are we key in code according our model or other model are we want to use?
If you free, can you update instruction? Sorry little bit confuse and thanks for your great job! :good::highfive:
Do i do your guide on Beta 11? or 4.0.2?
My telco using Band 5 for their LTE :crying: (other band will be expand)

If you need B5 use 1. A3000_us 2. Unlock B5 3. A3000_us 4. Set HW =226 or you can try another, maybe will work 237. and i'm on OOS 4.0.1

No B3 for US?

I'm sorry, i don't have US version
You need to test all of this for yourself

As i said that's all for testing.
