Recently I bought an s20 ultra from Ebay and I can't get it to upgrade. It says the operating system is up to date. I know I can do it manually if necessary. My question is why can't it do it automatically?

Is it AT&T locked or that (ATT) is just a coincidence? Maybe it really is the latest version for AT&T locked devices.

Thanks for the reply. Yes, it's locked to AT&T and I have checked on sammobile and there doesn't seem to be an update available for my specific model number but for the SM-G988U1 there are, also for other model numbers of the S20 Ultra, why would mine be left out, do you have any ideas?

Because your mobile carrier can't be arsed to validate the update and distribute to its locked devices. I've heard a lot of grief over the years over locked devices and updates and being unable to tinker with the phone because the bootloaders are all locked.

Thanks I guess the best thing to do would be to have it unlocked and then hope it gets updated. or do it manually.

So I was plagued with the task of rooting an s3...
I managed to root and flash twrp. However I want to make sure before I flash a rom. Is the bootloader locked on NJ1 firmware?
SANSUNG-SGH-I747
VERSION 4.4.2
I747UCUFNJ1
it's probably been asked already but I haven't been able to find an answer. Thanks
The bootloader cannot be locked if the phone was successfully flashed with twrp.
The bootloader on the att s3 has never been locked, unlike many other phones from att.

Awesome thanks! Would you happen to have any insight on why the phone would be stuck in factory mode? And would flashing a new rom take it out?
What do you mean by factory mode? What message appears on screen when you boot the phone?

You have the international version of the s3? The North America version is either i747 or i747m?

Tried to unlock my phone from unlockriver.com (I did it before). However, I am on unlocked firmware and I was expecting an unlock code. However, instead I just got instructions telling me how to use the T-Mobile unlock app. I paid $45 for instructions on how to use something that will not work considering I have not had the phone long enough.

EDIT: To even use the T-Mobile unlock app I will need to revert back to T-Mobile firmware and then use the app. The device T-Mobile variant shouldn't even be listed on their site as it is just a scam.

on the site there is this
Remember: * if we can’t unlock your phone, you will get your money back.
get your money back. there is no need to unlock the HTC sim card I'm pretty sure. if your trying to get unlocked bootloader go here http://htcdev.com/ if your trying to get s-off also go here http://theroot.ninja/
Isn't there a law (at least in the US) that carriers have to unlock their phones for free so long as there isn't any payment due on the device?
Hi,

I'm not sure why it won't show on your device.
I have it on mine.
I'm using the China Dev rom though, and I'm in Indonesia, maybe it's a carrier specific thing?

i using global rom not sure if thats the cause
Using the global rom, it's also active here in Switzerland. Your provider has it enabled for your contract?
Which exact ROM version do you use?

Yes it is enabled, i was using Samsung S6 previously and it works. i'm using global rom 8.0.3.0 unlocked bootloader
No idea then, here it's enabled. Can't say if it's working though, as I barely ever make phone calls.
i just read from my country mobile provider it only supports volte on some devices not sure if thats the cause

The firmware (rom) installed is not a determinant of what your phone really is. I suspect this is a frankenphone. If you bought it this way, I would try and get your money back asap.
The only way to be absolutely sure as to what the phone really is and what firmware should have been installed on it, is to open it up and see what is stamped on the motherboard. Unfortunately with the firmware installed now, you have most likely, with an ARB of 4, negated any chance of unlocking your device unofficially if it is still bootloader locked or doing much else with it for that matter.

Android 6 and on Developer Options I enable BootLoader Unlock but after enable he still disabled
I've only had my Pixel XL 2 for about a month. It was given to me and I know it's an older phone, but I like it a lot so I'm going to use it a while.
Anyway, playing around with the radios and APN's my phone says that there's access to 5G, but I didn't think this was a 5G phone. So is it possible to get 5G with the Pixel 2 XL? I'm on T-Mobile at the moment. We have 5G in our area with T-Mobile.
So like I said I'm curious if I can get 5G on this phone and why it says 5G recommended in my network options and why there's "NR" radio options in the radio/band settings menu.
Thanks for any insight into this!

No way you'll get 5G without the hardware.
That it shows in your settings must be a bug - probably a T-Mobile bug. It is not listed on my phone.

Sorry I've taken so long to reply to this. And yeah I thought the same thing also, that the SD 835's modem doesn't have the necessary hardware to get 5G. I have a Verizon SIM in my Pixel XL 2 now as of the time of writing this, and the NR option is still available in my radio menu. So idk if it's a T-Mobile bug or just a bug with my phone. It still gives me the option for 5G recommended in my system wifi/network/bluetooth menu also. But ya know, never connected to 5G so idk ya know? But thank you for replying!
