Re: Flashing unlocked phone questions

I have carrier. ATT locked. I was trying to change to unlocked XAA.

You used Odin patch B?

Re: Flashing unlocked phone questions

Yes. I spent time on it. I got frustrated that it didn't work. The Complete write (failed) thing was really strange to me. I will try again today by changing my USB cord maybe.

Re: Proper T-Mobile firmware?

Yeah try different ports and cables

I guess this does not work for ATT. Neither Frija nor SamFirm can find firmware.

Re: Flashing unlocked phone questions

This is the steps :

Windows computer needed

Latest Odin can Google it from XDA Forums and download the latest should be Odin 3.14.1 B Patch / and Frija tool or samfirm (i usually download both)

Download samfirm v0.4.1 tool and frija, extract it with 7zip.

You will extract files for Odin prince comsey 3.14.1once download with 7zip and will do same for firmware with 7zip .

Put your model number then region and select check for updates , then download the FIRMWARE , extract the FIRMWARE with 7zip.

There will be 4 files after you extract the firmware


BL

AP

CP

CSC

Each of those files will go in Odin when you open to the corresponding slots

BL

AP

CP

Home slot don't put anything

CSC USE HOME CSC FIILE TO SAVE DATA /THIS ONLY GOING BETWEEN CARRIER FIRMWARE OR IF YOUR ON UNLOCKED GOING BETWEEN UNLOCKED FIRMWARE

If you going from carrier to unlock firmware keep regular CSC not home CSC and do a back up it will factory reset the device.

connect your phone with cable to computer , once the files are in its slots hit start, once done you'll see pass in Odin and it will reboot





*Make sure you put phone in download mode
*If dont see your phone connected in Odin change cables or ports in computer .
*Never disconnect the cable in middle of flashing.


Use model # SM-F926U CSC -VZW

What do you select to go from Verizon to unlocked?

You have to choose U1 model then use Prince comsey (PatchB ) and use home csc so doesn't factory reset

Hi all, can someone guild me to install the OEM 12, 12 android firmware?
My Z Fold 3 currently is running 15, after 14 update, no sound now. No sound from either screens or open or closed. I read from samsungs community after 14 others have no sound. I posted on the XDA forums and nice replies, stated could be the hinge cables. I have never changed those. I have done batteries, front screens. Looks like the inner is difficult, the cables are $19, its the possible of ruining the inner screen.
I would rather first rule out the software if possible. If it is then i will try to tackle the cables. It is no longer under samsung care, it is a SM-926U1. I tried to flash it from samfw but it failed, maybe i have the wrong software.
Any help would be greatly appreciated. Thank you

Hi unfortunately you won't be able to downgrade from Android 15 to 11 or 12
I would let Samsung look at it or repair
