How To Guide SM-S918U S23 ULTRA/918U1 UNITED STATES FIRMWARE FLASHING

[EtherealRemnant]

Nevermind. Backed up my stuff and fired up SamFw Tool. Was expecting to have forcing CSC factory reset but it rebooted and came back up just fine. Had no signal and SIM Manager wasn't working so I rebooted a second time. Once it came back, it popped up asking me to choose which SIM to program the phone for and at that point I disabled CID Manager with ADB AppControl. Rebooted again and now I'm XAA/XAA,XAA/XAA and I can swap between my SIM cards at will without having to reboot.

What firmware can I use for S918UZKFXAA - This is S91U1 Model, got it today and waiting to get/see OEM Unlock in developer options.

waiting to get/see OEM Unlock in developer options.

You will never see it. That feature doesn't exist on US and Canadian models

 

[eatspizza]

Really, is that because it's not a carrier specific phone, so I don't need the OEM unlock to root?
I know my unlocked moto g 5g has oem unlock

 

[butchieboy]

You need unlocked bootloader to root.

 

[butchieboy]

Moto totally different device

Well i guess there is not such a way to unlock the bootloader from what i've finding so this will be an easy return

If you want a rootable device, US and Canadian models are useless and worthless to you. So yes, you should return it for a refund and buy a different model which does have OEM Unlock

Gotcha, which would have to be a carrier specific phone instead? My wife got the same phone and activated on ATT and her model code is different from mine but still unlocked ultra,

Model numbers ending in U, U1, and W do not - and will never - have OEM Unlock

 

[eatspizza]

Alright, i'll just get mine from att, didn't want to be carrier locked but that sucks they didn't get oem unlock for the unlocked version, make it useless for those that wanna root.

 

[butchieboy]

The carrier locked will not have OEM either

I don't think you're paying ANY attention to what I've been saying.

1. You said your wife got hers from AT&T

2. Your wife's model number ends in U

3. I said that model numbers ending in U, U1, and W are NOT bootloader unlockable

4. If you also buy a phone from AT&T, it will also end in U, and will also NOT be unlockable

she didn't get hers from att, we got same ones unlocked from bestbuy so we're both U1 but if ATT is U as well, then i'll just get a motorola so i can root that

From the screenshot of her details, it looks like the model number is U, not U1

But anyways, doesn't matter

So I keep reading that you need to wait 7 days and then some say you can't. Should I just return this phone to att?

 

[butchieboy]

You will never get OEM unlock on At&t device. This was recently discussed in post above yours. Waiting 7 days does nothing.

No OEM unlocking on any US or Canada variant devices. The international variants lack appropriate software support for US networks and would be a poor choice as well.

Already started the return. Going to pick up the OnePlus 11 instead. Sick of my oneplus 9 pro

 

[butchieboy]

Lol...OK good luck. Thanks for letting us know you have OnePlus
