Tutorial How to view Network/Bands

Hi Everyone,
Many People here want a 100% confirmation of what Bands this phone supports, i am also interested in this. I want to know Both 8gb/12gb band differences. I am currently waiting for the shipment of the 12gb ram version of the phone. I am providing a quick simple guide on how to show/list network bands, Please keep in mind that below is a guide from "ANOTHER PHONE" (screenshots are from a galaxy phone), I am asking for you to follow the same steps and reply with your own screenshots showing the supported bands from both 8gb ram & 12gb ram versions:
Requirements:
1) internet connection
2) Rooted phone
3) Download/Install this app called Network Signal Guru
Follow below steps :
1) Open Network Signal Guru, it will ask for Root access, and 3 permissions, say yes to all
2) Click the menu Button (picture 1 in attachments)
3) Select "Lock Rat" (picture 2 in attachments), this display supported Network type (as shown in Picture 3 in attachments) (WARNING, DO NOT select anything, take a screenshot and press back.
4) Click the menu button and select "Lock Bands" (Picture 4 in attachment)
5) Here you will have three options to select from: GSM, WCDMA, LTE, select one of them and take a screenshot and hit back, do the same for the other ones: WARNING, don't uncheck/touch anything. (pictures 5-9 shows an example each)
This app only works with Qualcomm processors, i am expecting that this guide also works with the Asus Rog Phone 2 (no guarantees)
After you got your screenshots, you can uninstall this app, please reply back showing bands both models support.

can the phone be unlocked to support many LTE bands or it should hardware support also?

Thanks JasonX,
Your screenshot confirms the 8gb ram version of the phone. Would also like to thank you for your other well-informative posts, easy to understand, very helpful guides. Im sure you took your time writing your posts to help others here at XDA, it doesnt go un-noticed, and i appreciate your posts.
To All,
Now we need a screenshot of the 12gb ram, please someone post it, it should contain more bands.

So no difference between WW and Tencent radios? I ask this because of the post: https://forum.xda-developers.com/rog-phone-2/help/asus-malaysia-addresses-key-differences-t3961135
They show the bands in their image from the Malaysian site. I was under the impression that the WW ROM exposed a couple of new bands.

Band 28
Hi, I have the ROG 2 tencent version 8/128
Before I flashed the global rom, the phone was able to connect to band 28 fine, so I found this thread to try to get that band 28 re-enabled. ticking the Band 28 option actually enables it again, but when I reboot the phone the settings don't stick. any tips? would like to get the settings to stick then, unroot then relock the bootloader so it's back to factory state. thanks in advance!

Hi could you share tutorial how to flash cn to ww rom?

During initial setup of the phone it updated to firmware 1907.33. I then searched around and followed these steps.
1. Remove Google account from phone
2. Install Asus bootloader unlock tool apk
3. Run Asus bootloader unlock tool and let it wipe the device
4. Rooted with patched IMG file from this thread (start at step 3)

Unlock BAND 20 LTE

Hello folks, i need your help to unlock the band 20 of redmi K30 5G. Currently i have Chinese rom installed .
Is a way to unlock the band 20 ? I saw new Xiaomi MI 10, if you change the rom will enable the band 20 . ( in that case is a software limitation)
In our case ?
Thank you !

Nobody can help me ?

i dident tried . i dont think to work, is an old version of snapdragon

Let us know if you're making progress... Trying the same thing with a K30 pro.

Any update? Id love to own this phone but need band 20 here in switzerland. Its the only one deactivated that i would need

People tried to unlock bands at the poco F1, but, there was no success, And people tried a lot

I found the possible files causing the restrictions on LTE and 5G bands, but I have no idea how to modify them to unlock bands.
In the policyman folder, the files:
- china_msim_restrictions.xml
- disable_nsa_mmwave_bands.xml
- lte_feature_restrictions.xml
regards
Excuse my writing (I am using Google Translate)

These files doesn't unlock B20 - this is hardware limitation. Bands are configured to nvitems but on 5G phones many things changed.
But could you please share to me your modem log file so i can list all hardware supported 4G bands to my cacombos.com website? I have here instruction how to get log file: https://mt-tech.fi/en/how-to-get-4g...phone/#Method_for_Qualcomm_Devices_after_2020 and you can send it to: https://cacombos.com/contribute . This help me understand what bands & combinations this device support.

If you change any ROMs from global to China and vice versa won't unlock the bands. This is locked down with hardware, not software. Older Qualcomm devices could unlock bands with Qualcomm tools/programs. This isn't the case with newer models.

Buying N975U (US Cellular) and using in the UK

Hello, I want to get the snapdragon Note 10+, so a friend can get me the US Cellular N975U but I will be using it in the UK. So, if anyone can help to answer my doubts:
1) How do I check if the device is region locked?
2) Will I be able to receive the SW updates with my UK sim here? or am I going to be restricted to flash manually via odin etc?
Thanks in advance

Give this a look & then contact US Cellular with the device IMEI, they'll likely need it to check for unlock status.

As for getting updates with a non-US Cellular SIM Card, I'd definitely ask about that as well.
Hopefully, someone here @ XDA will chime-in with their experience.
