[Work in Progress] Trying to Unlock Bands (Including B20)​

Conclusion

Changing the NVRAM values, may be the first step in the right direction, but it's not the end. It needs more than this to enable B20 and more.

Introduction

This topic is work in Progress; I edited some NVRAM values in hopes to unlock more bands for the Xiaomi Mi5. Have a look at the following topics.

I've tested it and by the result is that the NVRAM values alone are not enough to enable more bands. In the next paragraph I will shortly explain the test setup and test results.

About the test

Test-Setup:

Xiaomi Mi5, In Norway where carriers use Band: 3, 7, 20; Band 20 is for rural areas; Band 3 and 7 are for crowded places

How did I test the NVRAM values:

All but Band 20 were disabled, and I drove out to the countryside (rural area)

Result:

No Band 20!

Conclusion:

The NVRAM values are a good start, but not enough to enable more LTE operating frequencies.

Short Documentation: A short documentation of the performed test.

Original Bands

4G	FDD-LTE bands 1 / 3 / 7

4G	TDD-LTE	bands 38 / 39 / 40 / 41

What will happen next?

4G works on Band: 3, 7 and 20 in Norway. Usually, Band 20 is used in rural areas, and Band 3,7 are in use for more populated areas. As I live in Tromsø, I had 4G out of the box.

So I will have to go out of the city, to test if Band 20 is active, after changing the NVRAM values, on my Xiaomi Mi 5.

Why post this now and not wait a bit?

Maybe there's a mistake in here, and someone has the time to find it.
[Xiaomi Mi 5 Guides, News, & Discussion] TheUltrametricSpace:
Why have this value?​

​

If you look at it in binary, each 1 represents an active 4G band. So by changing values from 0 to 1, in theory, additional frequencies are enabled. (Only if the hardware allows it.)

lte_bc_config (64-bit, of which 44 bits relevant):	Bands Active:
2061584302149	00011110000000000000000000000000000001000101	1.3...7. 38-41

How can you help?

Double check the numbers and share your knowledge, pretty please. If something looks fishy to you, ask a question.

MTK has an engineering mode where it's easy to see what bands are enabled. Is there something similar to the MTK engineering mode for Qualcomm SoC's? Is there an easy way to test enabled bands?

What hardware is inside of the phone?

(Just another wild guess, be careful)

I googled a bit, instead of learning Norwegian and found the following. Link: Intrinsyc Introduces Qualcomm Snapdragon 820 Cortex-A72-Class Development Board, SoM and MDPs

How did I stumble upon this, I read on en.miui.com that the SD 820 has Qualcomm WCD9335 audio codec, and so found that link.

In the link a as connectivity the following hardware is stated: Qualcomm IZat Gen 8C GPS (WGR7640); and googling for this brought up that the same chip (WGR7640) is used in the SD 410.

One phone that has the SD 410 is the MOTO G (2015); so that allows us the very wild guess that the SD 820 will support at least all the bands of the SD 410.

Please share your opinion on this matter.

Try with "lte discovery" app.

On Samsung phones you can use *#0011# code to check it, but I'm not sure wheter it does work or not for other phones.
[Xiaomi Mi 5 Guides, News, & Discussion] idranoel:
I have the MI5 and I'm in your same Situation, ist not really needet to unlock B20..... but I can try.

I'm not expert, but I have a Problem to see on what Band I am.

I tryed a lot of apps..... discovery lte say me "lte band unknow".....

so if I make changes I can't see if they works..........

Doesn't work for me either, tested with LTE-Discovery in Version 4.4 and MIUI 7.2.6

@ TheUltrametricSpace : your mi5 is unlocked? rooted?...... I was thinking that because my is locked unrooted that I can't see the lte band.
[Xiaomi Mi 5 Guides, News, & Discussion] TheUltrametricSpace:
My phone is unlocked but not rooted.

I would assume that the app states somewhere "I want root", so don't think it's needed. But I don't know.

I tryed to send an email at the "lte discovery" so know what's the Problem....
[Xiaomi Mi 5 Guides, News, & Discussion] oile:
I guess that root privileges are necessary. We would have to analyze what scripts this software uses to state it with certainty but it would be better to have it rooted before trying.

[Xiaomi Mi 5 Guides, News, & Discussion] St3pH56:
It's written in the app description -> "Identifies EARFCN and Band for any country/provider when using a Qualcomm processor and ROOTED" :)

[Xiaomi Mi 5 Guides, News, & Discussion] duraaraa:
Would it not be simple to disable, first, all LTE bands. Then ensure you don't get a signal. Then enable just the LTE band you want to test (20 in this case) and see?
[Xiaomi Mi 5 Guides, News, & Discussion] TheUltrametricSpace:
That's more work than just rooting the phone and using LTE Discovery.

At least, I don't have the time disable all bands but B20... drive to (and find) an area where B20 is active, test it out .... go back home and start all over again.
[Xiaomi Mi 5 Guides, News, & Discussion] idranoel:
I think could be a good idea to enable only the B20, I don't know exactly how my carrier send the 3 bands in my Zone. If they send all 3 bands 3-7-20 in the City.

The Problem is to know where can I find a covery area for the B20, than your idea will be good.

First I have to be sure that if something happen at the phone, I can reinstall it. I read that with Mi PC Suite is possible but now is not supportet the mi5 on this tool
[Xiaomi Mi 5 Guides, News, & Discussion] kylemd:
Could always take a laptop with you :silly:

Seriously though as long as LTE Discovery is doing its' job though you wouldn't need to disable the other bands.

Keeping a close eye on this thread :cool:
[Xiaomi Mi 5 Guides, News, & Discussion] TheUltrametricSpace:
Right, yes I have a notebook, and will bring it to the cabin next weekend. (Where there should be B20) ... if I didn't root the phone by then, I will go for your suggestion :)

Also this one might be of interest. I only plan on using mine in the middle east. I'm removing the cameras from my phone and filling in the camera cutout for work in a high security offshore installation. So the LTE bands are really of no consequence for me but that doesn't mean I can't help scour for info. Seems some progress was made here...

the guide confirm unusability of band 20
[Xiaomi Mi 5 Guides, News, & Discussion] j2002:
I'm supposing this unusability is related with opo and its hardware and this is not related with our phone (or maybe yes).

I'm still wondering how art000 knows it is working in his case.
[Xiaomi Mi 5 Guides, News, & Discussion] Joboy13:
What j2002 sais is true. The Band 20 unuseability is for the OnePlus 1. The Mi5 has different hardware (and software). The thing is, we probably have to use a custom kernel (to negate the anti-tamper code from qualcomm), which without the source code is nearly impossible to make.

I do have high hopes for this, as MIUI 8 will come out 10 may and maybe they will release the source code of MIUI 7 for the Mi5.
[Xiaomi Mi 5 Guides, News, & Discussion] NZnewbie:
Im with you.... Lets hope they do release it sooner rather than later. I dont mind 3g only atm but that will change :)
[Xiaomi Mi 5 Guides, News, & Discussion] Termynat0r:
Maybe we can ask on the Xiaomi.eu forum.

Since they released a rom, they might have some source code or could implement the patch that allows us to enable band 20.

Agreed. I know that people have had success with other qualcomm devices but they have had to use custom kernels and ROMs to negate the anti-tamper that locks the bands. The Samsung Galaxy S5 is a good example.

Why would Qualcomm put in anti-tamper code into the kernel, locking bands? The price manufacturers pay should be the same no matter how many bands are opened, right? All I can think of is that the antennas aren't optimized (or tested) for the additional bands, and that's why they've locked them, not to give users the opportunity to complain about sub par performance?

Let's hope we get this solved soon ☺️ Thanks for all the testing and effort put into this but all of you guys already!
