How To Guide F711U and F711U1 Firmware Links and Flashing Discussion Here

[Solihudeenconcept]

Flashed a physical T-Mobile F711U to a F711U1 XAA firmware using Odin(Can't stand the bright pink boot up animations).

Flash worked perfectly. But, when I tried to test doing an update from Google settings it failed every time with "Registration Failed". I flashed the device back to the T-Mobile F711U firmware and was able to update without issue.

Not sure if you ran into this issue, but it's worth noting you might not be able to update the phone if the carriers are checking the Firmware.

Edit: Also forgot to mention, had to use the patched Odin due to the Firmware Model mismatch. Phone does work properly though.

How did you flashnit back... I have been trying tonflash my Z Flip 3 back to F711U after I flashed it to F711U1... it has not been going through... please put me through how you flashed it back

Simply saying "not going through" doesn't give us any details. You need to be specific, and tell us exactly what happens, including any errors that appear in Odin or on the phone screen

I'm presently trying to Sim unlock my Tmob Flip3. I willing to go to an unlock service but most can't work with the Tmob unlock method. They just want to provide an unlock pin for you to enter. Does anyone know of a work around such as mybe flashing another carrier' rom such as Verizon or US Cellular? Just wondering if one of these would pop up the message to enter an unlock pin when a I put my mint mobile sim in???

If the phone doesn't ask for a code by default, then no working code exists for it. Even if you could somehow force it to prompt for a code, it would reject any code that you enter. Unlocking it isn't anywhere near that simple

YAY! I bought a F711U from ebay that was locked to Verizon ("sorry, a carrier switch can't be performed at this time...") and it refused my Hello Mobile SIM. Verizon refused to help as I'm not a VZW customer of course.

Flashing the U1 firmware worked a charm! and the verizon bloat is gone to boot! And I didn't need to factory reset!
EDIT: JK, message still appears and SIM is shut off, but it takes several minutes from boot to happen.

How I did it:
- Odin 3B Patched v3.14.1
- Bifrost tool to download all the files (did not need any of the outdated ones in this thread)
- Fill in all the slots as the files are named, I did CSC in CSC (not HOME) and yet my data was still not wiped
- Leave USERDATA blank (instructions were unclear so I filled the remaining file HOME as there was no USERDATA, thankfully this caused no problems)
- Reboot and then insert new SIM. Works! Then stops working after some minutes because you gotta reboot.
- Reboot again! also notice, no more bootup animation or bloatware!

Uhhh, flashing U1 will never magically network unlock a device...

Even on U1, you should still be getting the popup about not being able to use another carrier

You're right... I didn't expect it to be so delayed, everything worked for a good 20 minutes before the message popped up again. Oops, scratch that.
Guess I'll try nagging VZW support again.

I don't think the device can properly process the unlock signal from Verizon while it's on U1 firmware. So you'll likely need to flash it back to U, with all applicable Verizon bloat, if they do indeed agree to do it

One UI 5 is out for South Korea and UK. Anyone can grab the update file?

Edit: I found this guide on how to grab it.
