[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] jazee:
I have the Samsung Factory Unlocked version of the S20+ (model SG-M986U1).* This means the phone is not carrier-specific, it works on all carriers (CDMA, GSM) and supports both millimeter wave (Verizon 5G Ultra Wide UW) AND lower frequency band 5G (usually called Sub 6).* The 5G UW super fast network is typically only available in highly populated areas (cities) because it that frequency signal doesn't travel very far and is easily blocked by buildings.* However you will notce the Verizon 5G coverage map shows 5G as being pretty widespread across the country.* Most of that is their Sub 6 5G Network which was launched in mid October 2020.* The 5G Sub 6 network, to my understanding, is using some of the same frequency bands as 4G so essentially it's really an amped up 4G signal using what is called Dynamic Signal Sharing (DSS)*(A lot of people don't understand all this.)*

I'm curious if there's anyone on the forums with a factory unlocked version of the S20 (typically the model number I think has a U at the end instead of VZW) can confirm if their phone shows a 5G icon when you are in sub 6 5G or does it show "LTE+"* I read somewhere the unlocked phones show LTE+ because technically that is what Sub 6 band 5G using DSS really is and 5G in that case is more of a marketing term.* Because different carriers use different terms for different networks, the factory unlocked phones can connect to all the different 5G networks but they can't accomodate all the different marketing terms.* I'd also be curious if when connected to the millimeter wave 5G in the cities if these factory unlocked phones show the "UW" designation which is bascially a Verizon marketing term, or if the phone just shows "5G".

There was also an article that talked about these phones needing a software update to use 5G and supposedly the updates were pushed out right after Verizon announced their Sub 6 5G network launch in mid October. But the author wasn't sure if the Factory Unlocked non-carrier specific models would receive the necessary update. Considering Verizon and Samsung just signed a 6.5 Billion Dollar agreement for SAMSUNG to further build out their 5G network, I would be very surprised if it were the case the factory unlocked models didn't get the update.

My S20+ model SG-M986U1 is showing Service Provider SW Ver. SAOMC_SM-G986U1_OYN-VZQ_QQ_0027 wondering if that's the 5G compatible version?

The other thing is a lot of people just swap SIM cards when they get a new phone. With 5G in most cases, if your SIM card was issued may months ago, you need to go into the carrier store and have them give you a new 5G compatible SIM card. I honestly can't remember if my phone was showing LTE or LTE+ before and after SIM card change. I tested the bandwidth after the change and in a strong signal area got 60mbit download but I didn't have a pre-SIM swap test in that area to compare to unfortunately.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] jazee:
Well I feel like I'm going in circles but now found a Reddit thread that confirms what I originally suspected.

The Factory Unlocked (model ending in U1) S20 phones apparently have not got the update from Samsung yet to allow sub 6 5G connection. But there is a hack in that you can change the carrier network code to ATT even though you are on Verizon and it enabled the N5 band which is what Verizon uses for their "Nationwide 5G" To do this you dial *#272*your IMEI number# Then select ATT and Install and change network code only. Phone will reboot and now you will see 5G UW symbol.

I tried the CSC change on my factory unlocked S20+. I ran three successive bandwidth tests on bandwidthplace.com before and after the change so 3 times on VZW and 3 times on ATT. As others have alluded to the LTE DSS Sub 6 Flavor of Verizon 5G is on average about the same speed as 4G LTE+. So I just turned it back to VZW and will wait for the update from Samsung. I'm surprised a month and a half later it still hasn't got the update to allow N5 band on Verizon.

I'm also wondering is the S20 always show 5G UW when connected to any 5G including sub 6 5G and not actual millimeter wave ultra wide 5G? Or is that just a side effect of "spoofing" the ATT carrier code when actually on a Verizon network IMEI?
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] chesterkatz69:
Hello Jazee, this is my first response to anyone on xda, and I know that by now you probably have your answer I notice this is an old post. I have an unlocked Samsung s20 5g. And depending on where I am, it says 4g let, and when I'm closer to the city, or hold my leg right(I live in the country), my phone shows 5g. It's shown lte+ before. I think it depends on your carrier. Some I've noticed share 4 and 5g lte simultaneously depending on the current speed. As you mentioned earlier, 5g signal doesn't put up a big fight when it sees a tree or building. Anyways, that's my 2 bits worth, hope this helped. BTW, lte+, when I get that, it is pitiful. Nothing like either 4g lte or 5g lte.
[Xiaomi Mi Max 3 Questions & Answers] hassan216:
Can i flash a custom rom similar to stock Android on mi max 3

Im currently on miui 12

I still didnt unlock the bootloader

I keep hearing something called antiroll back and bricking the device

So please if there is anyway kindly put a link for instructions as my knowledge isn't great at flashing roms.

I am following this guide

gearallnews.___/how-to-install-lineage-os-17-on-umidigi-a5-pro/ (sorry for the circumvent. felt it was important for the pros to check the source)

since I have a newer phone (at the time of this writing) Android 9.

but regardless of the above site or any instructions regarding "adb" and "fastboot" it always takes me to the black screen with tiny print at the bottom that says "fastboot mode.." and thats it. If I just do Vo+Pow it will take me to a menu from clearing cash to rebooting the system and factory reset. Can even boot to bootloader, but it gives me the same black screen with those tiny words at the lower left of the screen, everything else is blank.

I have to use the power button to shut off, then again to reboot to normal.

when I type fastboot devices, nothing,

adv devices (before the boot) will show the correct phone

All the other UMIDIGI AS5 PRO tutorials seem to work fine.

This is a dual sim, unlocked phone.

Any suggestions?
[Upgrading, Modifying and Unlocking] Deleted member 11273737:
OK fixed all the issues (a5 pro driver missing, FIXED, mtk67xx installed)

(thought) I installed TWRP but when booting to bootloader, all it says is "fastboot mode..." and the screen in blank

So tried a different method, by rooting this from scratch, so first thing was to make a scatterfile.txt

Powered up the MTK DROID ROOT & TOOLS and got the following message (of course because of this, cannot use the ROOT button successfully)

--->>> Connect to device <<<---
--- ERROR : --- TotalBytesPerChunk Not Found. Set default Page/Spare=2048/64 !!!
--- Unknown ROM structure, backup NOT possible!
ATTENTION! File /system/recovery-from-boot.p which restore factory recovery in case of phone switching on in a normal mode Is Found!
"/data/local/tmp/pwn": error: Android 5.0 and later only support position-independent executables (-fPIE).
ATTENTION! Requests for confirmation on the device screen are possible!

What to I have to fix/clean up?

Thanks for any suggestions

EDIT: Yes the phone is still working fine, (other than th emessage the phone is not safe because the booloader is not locked)

Hi all

Just bought a Pioneer DEH-P700BT Bluetooth headunit, my XDA Orbit will not pair with it. It used to pair with my old bluetooth headunit but not this one.

From reading around it has known issues pairing with PDAs but apparently there are ways around it

Are there any mods I can do with my phone to make the bluetooth pair with the P700BT stereo?

Help appreciated
[Android Q&A, Help & Troubleshooting] decemberhat:
(this is my first post, so I apologize if it's in the wrong category)

I bought a used tablet that was originally sold by AT&T. I unlocked it and wanted to use it as a hotspot, but the settings menu for (a) configuring the hotspot and (b) enabling hotspot and tethering is missing/hidden. (Apparently the original data plan it was sold under didn't include connection sharing, or something.) So I couldn't set up a hotspot or tether.

I've been able to do 2 things so far using adb:

add a quick settings tile for turning the hotspot on/off (via this post).

This is great, but doesn't ultimately help because I'm not able to configure the hotspot (i.e. set the name/password) and I can't connect to the default hotspot it apparently enables

get the tablet to display a limited settings menu that lets me (a) turn usb tethering on successfully, and (b) toggle the hotspot - but again without being able to configure it. [adding to clarify: the menu has just those two toggles, but no settings for actually configuring the hotspot.] The command I used was:

adb shell am start -n com.android.settings/.TetherSettings

What I want to be able to do:

get the tablet to display a menu that lets me configure the wifi (name/password), or alternatively do the configuration via adb

if possible, get the menu I described to be permanently added to the tablet's Settings menu. Right now, whenever I want to tether I first have to run the adb command to turn on the menu that lets me enable it.

Is any of this possible?

The tablet is running 7.1.1.

Many many thanks for all help.

Why not create a .sh script - that runs the AM as shown by you - what is run when Android is booting?

If you have Magisk installed you can place the .sh to

/sbin/.magisk/img/.core/service.d/

or to

/sbin/.magisk/img/.core/post-fs-data.d/

( Don't forget to make it executable: chmod +x your-script.sh. )

Otherwise running .sh scripts when Android is booting can be achieved by Init.D Scripts app. A rooted Android is not required.[/QUOTE]
[Android Q&A, Help & Troubleshooting] decemberhat:
Thanks, that's an interesting idea. It has the drawback that I'd still have to be careful never to close the menu it launches, since once closed I don't know any other way to access it. But it's definitely better than nothing. (And I didn't know it was possible to customize init scripts! That is really useful.)

Any suggestions on a way to configure hotspot settings?
[Android Q&A, Help & Troubleshooting] decemberhat:
I should probably clarify: the menu I'm able to launch has only two items - a toggle to turn the "Mobile Hotspot" on and off, and another toggle for USB tethering. There's no submenu for configuring the hotspot, and I don't know how to access those settings.
[Android Q&A, Help & Troubleshooting] Deleted member 1890170:
I must admit that I completely misunderstood your issue. Now I know that's related to your Samsung device where you modified its quick settings menu. Anyway: you can't by means of ADB change layout of this menu.

Recommendation: Add SAMSUNG to start of this thread's title.
[Android Q&A, Help & Troubleshooting] decemberhat:
Ah, good point. I changed the title.

What I was hoping was that there was a second, separate hidden menu I could access for hotspot settings, similarly to how I was able to access the hidden top-level tethering menu.

Or, barring that, some way to configure the hotspot directly via adb commands.

Hello,

is there a specific easy step by step guide to flash Android 11 on Umidigi Power 3?

I read many articles on the web and I am pretty confused.

Looking forward to hearing from you!

[Android Q&A, Help & Troubleshooting] Deleted member 1890170:
Installing Android 11 GSI requires an Android device that is Treble enabled.

You check your device for this feature by means of ADB

adb devices
adb shell "getprop ro.treble.enbled"

If true is returned then you can flash Android 11 GSI

Hello,

thanks for your answer. I checked and my smartphone is treble enabled!

What procedure do you suggest to follow? I found many and I don't know which one to pick up...

Anyone can help me with the steps and the links to the files I need to use to install a working recovery? I'm on the latest MIUI 12.
[Redmi Note 9S / Note 9 Pro (Indian Model) Question] Jas Grover:
If you just want to root, it's possible without TWRP too

You need to be googling every fact that you don't know, cuz I did in the same way

1. Find the original ROM file online

2. Verify that the version is same

3. Use online extractor and find boot.Img

4. download it, install magisk apk, open it, browse the boot file and patch it

5. Now copy patched boot file to ur adb folder in PC and rename it to boot.img

6. use fastboot flash boot boot.img

7. You've got root access, magisk works, boom!

first check if you using the newest fastboot version via: fastboot --version

are u sure that you have the EEA Hardware?

when u have access to twrp(recovery) try sideload via adb sideload

this could happen to you with any device! for me the 7A is a really great device. if you unlocked your bootloader you know that there is always a chance to brick your phone! so take responsibility for your actions and don't blame the manufacturer.

PS: if you use more dots and enter it would be much more better to read through your post if someone is trying to help :/

I see the ethernet is actually a daughterboard, which is connected by a ribbon cable. Anyone think there is a chance this is just a USB-to-Ethernet hub? If it is, it would be an easy mod to swap over to a USB port, which would dramatically enhance the functionality of the non pro version. Why they didn't do this in the first place amazes me... it looks like a 10 pin ribbon cable though, so not sure if it's USB...

I'm interested in adding a USB port myself. But the mainboard has a Realtek chip (according to photos at fccid.io), which I assume is an ethernet chip. I have however seen people mention a soldered USB connector somewhere, but I haven't been able to find where.

Did you ever manage to find something out? I'd be happy even with SPI.

Got a brand new fire hd10 9th gen has the software it shipped with I didn’t do the OTA. Using fire toolbox that I got from xda thanks! I made all the mods I could and got play store set etc. got apps downloaded no big deal.

My problem is specific and strange to me. The app Jurassic world alive is important to the person this gift is for and google play states the app is incompatible with the device.

So I figured ok just side load no big deal I have a good apk of it from a good site and any time I attempt to side load it gets 3/4 through the install bar and abruptly changes to app not installed. No error message or anything else. Any ideas since I can’t root this and change the build prop to download it from the play store.
