A friend wants her A-14 SM-146U reflashed.

Looking for firmware - there are distinct file differences between the SM-A1426U and the SM-A1426U1.  She plans on using this on Spectrum which evidently uses Verizon's network much of the time.

The SM-146U has two possibilities -

XAU A146USQU1AVKL (2022-11-30)    Android 13

VZW A146USQS6CXC8 (2024-04-01)   Android 14

Which should I use?

Incidentally, the SM-146U1 uses the same for XAA and VZW

XAA/VZW  A146U1UES6CXC2 (2024-03-13)  Android 14

 

Thanks in advance 🙂

@qudrcps Models ending in "U" are carrier branded devices.

Models ending in "U1" are unlocked devices from Samsung.

Hmmm... interesting.  So if "branded" model has been unlocked, and the "unbranded" firmware has less "bloatware", can it be used one the "branded"?

Thanks!

A correction to the above - the phone involved was purchased from Charter/Spectrum (CHA) (not Verizon VZW).

It is currently loaded with A146USQU1AVL2    Android 13  (2022-12-15)   - this is the same as for VZW

The latest CHA update is A146USQS6CXC1  Android 14  (2024-03-11)  - this is the same as for VZW

There is a later version for VZW  A146USQS6CXC8   Android 14  (2024-04-01)

Obviously, this needs to be updated as it is a bit "flaky".

In considering an update, my questions are:

1. Is it "locked" (and how would I know)?

2. Is there reason the firmware is the same for CHA and VZW because CHA uses the VZW network, there latest VZW could be used for CHA?

3. Does "unlocking" the phone change it from a SM-A416U to SM-A416U1?

4. If 3 is true, can one use the A416U1 XAA firmware?    Currently CHA   A146U1UES6CXC2  Android 14    (2024-03-13)    This is that same as for XAA.

Thanks in advance 🙂
