Unlocking and Flashing to OEM Firmware
1. ATT changed their unlock policy on 3/18 to require 60 days of service before they can unlock a fully paid device. Previously, it used to be right away if you have paid in full.
2. There two timeline for the cancellation. If you cancel a line before 3 days it was active then the activation fee is waived. If you cancel it within 14 days from activation under buyers remorse then no bill is charged but activation fees need to be paid. The line activates on right when you place the order not the day you receive the phone on hand so you might have to pay the activation fee of $35.
3. You can use a tello number and port to ATT but you would have to make sure porting is successful by going to https://www.att.com/portstatus/. Many from z fold 3 got stuck in porting limbo and got the ATT account cancelled.
4. As with many deals here, a SIM swap method is found which can be used to unlock the device. This was working recently but not sure if ATT would fix it by the time you try it. The steps are as follows.
a. Pay in full for the phone.While your payment will quickly reflect in your account it will be at least a few hours before it updates for the unlock request.
b. When you receive the phone activate it on ATT with the SIM provided. Make sure it shows up on myATT app/in the web so ATT knows and registers the IMEI in the network. Then put the SIM in another unlocked phone, reboot, make some calls and make sure this unlocked phone is now showing under the line in app/web portal.
c. Now go to ATT unlock portal https://www.att.com/deviceunlock/ and then choose not an ATT customer and use the IMEI of ATT phone and submit an unlock request.DO NOT attempt more than twice or you will be blocked for 24 hours.
d.Confirm the unlock request email and receive the unlock code.
e. Only cancel the line after you have unlocked the phone.
Then after unlocking if you are feeling adventurous and want to flash the phone to an unlocked firmware to get rid of ATT bloat you can follow these steps. It's actually very easy to do with Odin.
1. There are many models of S24 ultra but in US two models are imp. S928U is carrier locked version and S928U1 is the unlocked US version. The firmware for these versions are interchangeable so you can flash the ATT model with S928U1 firmware.
2. Download patched odin v3.14.1_3B_PatchedD.zip from https://xdaforums.com/t/patched-o...1.3762572/ as regular odin does not allow flashing mismatched firmware.
3. Download the firmware from S928U1 XAA version from https://samfrew.com/model/SM-S928U1/region/XAA/ Extract as there will be multiple files.
4. Connect S24U to the windows PC.
5 .Put S24u in download/recovery/odin mode. Power down. Press Volume up and down together and then press Volume up to go into recovery (a green screen would appear).
6. Start odin and then select different files for different categories and then start.
7, It should be now the US unlocked version.

ATT requires 60 days active before unlocking the phone. However, there is SIM Swap method which worked well in the past for unlocking paid-off ATT phones right away.
0. Do the following steps after paying off the phone fully and then waiting for a day or so for the unlock portal to get the paid off status.

You should cancel ASAP. The clock starts from when the line is activated so during order/when the phone is being shipped out. There is no need to wait for cancellation if the phone is paid off. Make sure to get the activation fee credited etc as well during the chat
Yes they do run a soft check so you need to unfreeze them.
Do you think I did the canceling att service correctly?

You should try to chat again and ask for immediate credit on the current bill. That is better than waiting for credit to apply as doing credit on a cancelled account is tricky if things don't work. I think you did but make sure the line is cancelled.

Do you see the bill yet? You can get the activation fee voided instantly, see my pinned comment. I'd chat again, CS reps can apply credit to the current bill but I'd first void the activation fee myself.
Did you get email from VZW about new line/account? If so your line is already activated and the counter for 3 days has started. Unlike ATT, Verizon does not offer one time courtesy waive of activation fee. CS reps can apply any credit but it's hard to convince them.
I paid off the line I was trying to upgrade and unfroze my credit and I still get same "unable to retrieve account" error from Walmart. Anyone have an idea how to proceed?
