b20 research default value NVram - Xiaomi Mi 5s Questions & Answers

am conducting research on the band 20 for MI5S. I need know your default values NVRAM the following settings. The values you can read them by installing QPST and QXRD. Thank you for participating.
Below my original
441: 0x387
946: 0x04E8
1877: 562950035734915
2954: 131072
6828: 2061584302293

nobody?

Should be getting the device soon, I'll see then, also in the regular Mi 5 xda there was some progress with unlocking bands, maybe they can help.

The values are the same on every Mi5S. Did you try changing the lte_bc_config value to enable b20? But anyways I don't think it's that easy to activate b20 on the Mi5S.

not to dirty the other post, I created this my idea, is to verify this information on our devices, if they have a fixed value, or changes to the device, since the limitation is not hardware but it is "just" software.

yes, these are fixed values. You can calculate them with this app https://play.google.com/store/apps/details?id=org.vndnguyen.nvcalc
calculate the value including b20, change it on nvram and you should see if it's just software locked.
Edit: checked on my device and def. the same.

I know this story, my MI5S never finds any 4G network, pictured a MI5S and redmi notes 3 MTK. I can not find an explanation

Well,
I have an idea but only someone with Redmi Note 3 Pro could help us to active the Band 20.
Redmi Note 3 Pro have 2 Global Roms:
- Global Rom (without B20)
- Special Edition (with B20)
Some of RN3P are using the Special Edition in order to have the Band 20 enabled.
Since that I don't have the phone neither the proper technical skills, I'm not able to explore this idea. Hope that someone could help us to enable that thingy.
------UPDATE------
I've been doing some research:
In the official forum post about the Special Edition, Xiaomi tells that if you flash the Special Edition ROM on the Regular Redmi Note 3 Pro, you will wipe your IMEI information.
Since the IMEI info is on EFS partition, could be that partition be the key to unlock the bands?
Is anyone able to: Backup EFS\ Install Special Edition\ Restore IMEI Info and check LTE Bands on a Redmi Note 3 Pro?

The special Edition is snapdragon the note in photo is mediatek

I know man, we have to wait for someone to help us.

many views, few answers!

I highly doubt you could enable it just by changing NVRAM values, people have tried it on the Mi5 (http://forum.xda-developers.com/mi-5/how-to/progress-trying-to-unlock-bands-t3337476) but to no avail.
They're already looking at changing SNR levels and sync values...
My wishful thinking is that, since China Telecom announced that they'd start using LTE band 20 in 2017 we COULD get an update unlocking band 20, so people with Mi5s's on China could use band 20.
But, like I said, wishful thinking...

the problem on my mi5s is, that does not hook any band 4g. the question of the band 20 I know, my operator does not use it, use the frequencies 1800 MHz, 2600 MHz. b3 and b38, but I never find any 4g network.

To be on the save side have you tried already:
- with different SIM cards (maybe also of other providers)
- changing the SIM slot on your phone

Xsiriusx, some providers disable LTE on their side for certain contracts. You should call your provider and ask him if LTE is enabled for your contract and sim card.

Band 17 LTE?

From what I can see, the GSM unlocked version doesn't support Band 17. Can anyone confirm?
If you are talking about the US version, the GSM unlocked version of Z (not play) supports LTE band 17. Z Play unlocked version most likely will be the same.
The listing on B&H does have band 2 and 4, but not 17. Might be an issue on AT&T.
If you really need that band, you might look at the Mexican version. It supports: 4G LTE (B1, B2, B3, B4-AWS, B5, B7, B8, B12, B17, B19, B20, B28, B38, B40, B41)
This makes no sense for the unlocked version of the phone to not support AT&T's primary band for LTE. But to sell the identical phone in mexico with that band supported.... Maybe an error on motorolora.com?
I placed an order and then realized at&t might not actually supported. I tried to cancel and they make it impossible to do so. We'll see what happens but I'd be shocked if its not. I only looked because I was curious about band 30.
I have the Moto G4 2016 XT1625 and Motorola website doesn't mention band 17 for this phone either, but according to Signal check lite app it shows I'm connected to B17. So I must be a typo on their part? Let us know when you get your phone if you get B17

1) signalcheck isn't entirely accurate. It uses a database to infer lte band (based on network tower sector ID and other stuff). It doesnt ask the phone modem for the actual info
2) att's 700mhz block b+c spectrum falls under both band 12 and 17 now(12 is a superset of 17). Att broadcasts on both band 12&17 on the network side via mfbi, att will push for band 12 on newer phones instead of 17(17 will be deprecated, but continue to be used network side to support legacy band 17-only phones)
Both Band 17 or 12 phones can connect to this spectrum (aka your g4 2016 works on att's 700mhz). Again, due to (1), signalcheck might have old data saying it's band 17 even though your phone is technically connecting to band 12.
3) moto z play doesn't have 12 or 17... So who knows?
Thank you for the explanation! Well I guess I won't be looking at Moto Z Play then.

try https://play.google.com/store/apps/details?id=com.qtrun.QuickTest
Currently I get LTE on my Moto X Pure on AT&T, when my moto z play arrives today (hopefully soon) I will report back. Honestly though I only get 5 mbps on AT&T LTE where i live anyways so HSPA+ probably wont be much different in terms of speed. Data limits and local network server make me want to use wifi anyways.

Thanks for app! Looks like after all I am not on B17
Interesting... being on band 12 is OK. AT&T uses 17 (B,C) but 12 has A,B and C. I hope the numbers on their website are a mistake. I'm in the process of attempting to procure a mexican model but if this is true I can pick up the one off motorola.com
Just recieved my Moto Z Play (US Version). Put in my AT&T sim and boom I have LTE. I will check what band in a few minutes.
Edit: I tried checking what band I am using with the network signal guru, but it wouldnt tell me. LTE works regardless.
Awesome... looking forward to your results

try cclick the first wizard like button on top left (1st icon)
select band locking (not sure if you can select without root)
select LTE or wcdma or gsm,
depends on which one you need to check
and it will show all band which are supported from your phone

Hi..It would be great if you could give your APN Settings. My phone only shows "H" and no LTE.. I do not know if the phone does not have the bands or it is an ATT issue.. Thanks!

Does your phone still have a whole bunch of different apn settings in the apn menu? If so, I would select the apn setting with nxtgenphone or pta, I had a problem with not getting lte at first when I first got my phone but playing around and rebooting a few times eventually gave me lte.

Xiaomi Mi Max 3 Global (9.6.7.0) Freedom Mobile LTE?

Hello
I was wondering if anyone had any experiences with the Global version the Mi Max 3. Did i make a mistake of purchasing a Freedom Mobile LTE incompatible phone? Or it should be asking myself whether this is really the Global Version?
Boot-loader seems locked, box in proper English with UK adapter, that makes me think its the Global version.
When i put my sim card in Data works, SMS works, but no phone calls in or out, even tho in the Network options Freedom is fully detected as the HOME network.
Any ideas?

I bought one exactly the same, in the same version of global Miui (9.6.7.0) and had no problem at all. In the box that came your device is written on the side "global version"?

No, I'm in Brazil and here are other operators. These are the bands that the unit has:
2G bands GSM 850/900/1800/1900 - SIM 1 & SIM 2
CDMA 800 & TD-SCDMA
3G bands HSDPA 850/900/1900/2100
4G bands - LTE band 1 (2100), 3 (1800), 4 (1700/2100), 5 (850), 7 (2600), 8 (900), 20 (800), 34 (2000), 38 (2600 ), 39 (1900), 40 (2300), 41 (2500)
See if your operator has the machine's bands.
Sorry to be the bearer of bad news my friend but yes, you did just buy a phone incompatible with Freedom Mobile as I just did the same lol. Yes, messaging and data does work but you'll never get phone calls to work. I was wondering if it was worth sticking with Freedom anyways because of the deals but in the end I decided to switch over to Fido which works fine with the Mi Max 3. Also the version I have is def the Global Version (9.6.7.0) as I checked on the official website.

Haha yeah closure def makes things easier to handle. Tbh the phone is good enough that if you don't make a lot of phone calls it's still worth it but the problem for me is that in order to unlock your bootloader you need to get permission from Xiaomi. In order to get permission you need to have your device linked with your Mi Account. And in order to to that a confirmation text has to be sent (think Whatsapp). However, even tho you can send a text normally this automatic one fails to send on the Freedom network. So basically if you want to do any rooting whatsoever you'll need a SIM from somewhere like Rogers or Fido which ended up being the deciding factor for me aha.
If you have no plans on rooting then you should be fine :good:
Your phone should connect on LTE band 4 with Freedom Mobile. Mine connects flawlessly on LTE bands 4 and 7 with Telus.

moto e4 not picking 4g signals in pakistan

hi sir best wishes from pakistan for all
i purchased verizon moto e4 from karachi 120$ its best phone but not picking 4g signals i tried all network sims but vain
its hurting me every day my friend has moto 4g play his mobile get full 4g signal i surprised
pls tell me solution i serched in net many times but not get answer but today i looked this forum i hope you will never disappint me
if my post against wrong place then sorry
can i install moto 4g play firmware in this moto e4 pls solve my issue
3g speed 200 kb and 4g speed 3mb/second
i think i need to hospital for mind treatment
pls suggest me thnx
no reply i m disappointed
only tell me how it possible to bandwidth change in moto e4 i install mtk sof bt not working
Verizon model is not mtk. It's Qualcomm. You can't flash different firmware. If you can get the msl number you can change bands, but the device doesn't have all bands.
You need either root (not possible on Verizon, locked bootloader) or your msl number from the phones original carrier. That's why no one has answered.
Not likely any viable solution for you

No, actually there are different LTE bands available per region. The difference is less significative than, for instance, on 1+7, but they're still there (and the reason why I need to get the NA version, in my case).

Don't do it... the Chinese variant is missing B66/AWS3 which is in use by all US carriers. Read my other post: https://forum.xda-developers.com/showpost.php?p=80892995&postcount=8

So did having read that, if there is a 256GB EU version, get that as it has the B66, according to the Connectivity section: Bands (EU) FDD-LTE:B1,2,3,4,5,7,8,12,13,17,18,19,20,25,26,28,29,32,66
but I don't think they did
No 256gb variant that was released has band 66.

Don't do it... the Chinese variant is missing B66/AWS3 which is in use by all US carriers. Read my other post: https://forum.xda-developers.com/showpost.php?p=80892995&postcount=8

Appreciate this insight man!!
I'm in the US, NYC/NJ. I was super torn. I wanted to upgrade my op5. I wasn't a big fan of the pop up camera or the curved edges of the 7 Pro...plus I wanted a T.
The MacLaren edition is really nice, but...popup camera and like 400 more than the Chinese 7T. I couldn't justify it. So I took a chance and ordered the HD1900 Chinese version of the 7T with 265gb. So far, after about two weeks, it's excellent. I have no issues with not having a fast connection

No issues with not having a connection. Maybe it's because I'm in an area with good coverage (t-mobile). But so far, for $500 - HD1900 has been excellent.
I'm just waiting for twrp so I can root the thing.

You don't need TWRP to root it: https://forum.xda-developers.com/oneplus-7t/how-to/guide-how-to-root-oneplus-7t-twrp-t3979307/page56
Does anyone know if HD1907 US T-Mobile version works fully on Verizon i.e. HD Voice, Wifi calling and Visual Voicemail?

-1900 (pcs)
Umts and Lte:

Yes. Compatible.

Got the 7T rooted...no problems. Not used to doing it without TWRP, but it all worked fine. Magisk, root all working flawlessly. For 500, the 256gb hd1900 has been excellent. I know it didn't have band 66 (or something) but in NYC and Quebec I haven't noticed any problems. I'm coming from an OP5 and mobile connectivity is at least as good with the OP7T HD1900.
For me, the decision came down to value. I wanted the 256gb, which ruled out the US OP7T. The OP7 Pro is nice and I came close to choosing it but I don't like the curved screen edges and I'm not a fan of the pop up camera. The notch doesn't bother me. So, no 7T pro either. The t-mobile McLaren edition was tempting...12gb ram, 5g. But at almost twice the price...not worth it. So far very happy with the hd1900 in the US with the 256gb.
Once I got it rooted, of course.

Question LE2120 unlock 5G EU Bands

Hi,
my wife bought a brand new Oneplus 9 Pro as a present for me from Ebay.
They say that is "European International Version", infact it runs Oxygen OS 11.2.6.6.LE15BA.
A few days after receiving the gift I asked my operator (Fastweb) to enable 5G because it doesn't Work. They say that 5G is enabled by default, so i inserted my SIM card in a friend's Samsung S21 and... all was ok.
After some research I realized that they had sold her the Chinese version that supports only few 5G bands (not the italian of course) flashed with the EU ROM.
Now the question is: it's possible to unlock missing 5G frequencies?
I tried to modify carrier policy.xml, but with no results.
Pls, help me.
No you can't, hardware (I mean including non-flashable memory) is completely different.
Completely different?

Theres a workaround. Try this:

No you are wrong it is not hardware. All use same snapdragon with the same modem inbuilt. So it can be fixed.
I've just modified the xml like in the First post.
But...

Technically it's the same hardware, but the bands are baked into the baseband firmware and not user modifiable. Messing with carrier_policy isn't gonna change that. Unfortunately OP is SOL, hopefully it's still a good 4G device for you. Here is from mt-tech (author of the qtsp article)
This instruction only allow enable/disable 4G Carrier Aggregation & 5G EN_DC combinations and band support if hardware support it. If hardware doesn’t support, you can’t enable/disable band. Example OnePlus 8 (China) 5G doesn’t work in USA even it support n41 (T-Mobile/Sprint) band because it doesn’t support 4G anchor band used in USA.

We see this all the time, where Chinese OP devices are sold by 3rd parties cheaper but does not support everything and then people complain.
And it's possible to flash a different baseband?

The "baseband" you flash (non-hlos / modem.img) should be treated more like a driver for the hardware you are running. Technically it's more complicated than that since it handles the low level modem stuff prior to Android. There is no (known?) way to modify the actual firmware by the end user.
Oh... I remember that on the old S3 it could be done. If the hardware is the same we could try.
But it pains me to think that we have been scammed, that my wife threw a month's salary away and that I find myself with a neutered device.
Sorry to hear that, hopefully it's within the seller's return period. It's usually a caveat emptor kinda thing, the listing will usually tell you exactly which base model it is and the bands listed. If the seller misrepresented the device as a LE2123, then you can probably dispute it. Otherwise, most sellers offer a return period with a restocking fee.
AFAIK, the older device's modem img is actually the entire baseband and not non-hlos, so it can drive the entire modem.
First of all thanks for understanding.
So, do you know where to find the img and how to flash?
In the meantime, I try to contact the seller: luckily I haven't removed the protective plastics.
The Global ROM (AA) has the global non-HLOS, EU (BA) has theirs, etc. You can extract them from the OOS full update images, but like I've said, it's not gonna make a difference.
Hum... I will try.
Do you know if there is a standard procedure to do this?
I had LE2120 Chinese on AA version, no volte no 5g

I tried, but with no luck.
In the first post you can find my modified subscriptions.xml, but i think the problem is at the firmware level.
I also tried to delete the "persisted_items" subfolder in order to recreate it with the new policies, but still without success.

Are you getting 5G in Zain KW? Even I get 5g in preferred network type. But when I select the option, I see the same image as highlighted. there is no option to select 5G
Just to clarify, i see this:
but no 5G connection in signal status.
Once again: i'm in 5G zone and my operator (Fastweb IT) supports 5G by default for all customers.
This is the result of scan. As you can see, no 5G networks can be found.
