How To Guide F926U and F926U1 Firmware Links and Flashing Discussion Here

[iBowToAndroid]

Hello, U1 download link says it's empty

Yep that's because anyone can download it themselves at any time from Frija and the other various firmware download tools - and at (usually) much faster speeds than AFH

Hello guys. I was wondering is that possible to convert F926U (i have unlocked ATT) into F926B? The reason why i'm asking is because i want to have two sim card and i can see second sim card contacts in sim-tray.

I was curious if i try to flash global firmware and order a $5 new dual-sim card slot from ebay will it work? Or i will brick my phone?

Hi guys. After changing to U1 on ATT I noticed sometimes my phone is unable to receive or make calls until I put it in airplane mode and remove it. I was expecting a call for a job interview and I couldn't get it because of this issue. Are there any fixes for this problem?

I've a f926U with ATT I'm trying to reflash to TMB to get all the bloatware and customizations

I downloaded the latest with TMB csc with frija and installed them with odin with the full csc + userdata

my csc is still showing up as att/att/att with my tmobile sim and I'm still seeing att bloatware and boot screen.

what am I doing wrong?

Well, my best guess is you're not using the patched Odin. You need to make sure your CSC (in the phone and in Odin) shows as TMB and need to flash U1 firmware with T-Mobile USERDATA.

ok I was able to get it going.

for w/e reason using a tmb sim in my device didn't change the csc if I was using the U firmware. it kept it at att/att/att no matter what.

I reflashed to the U1 XAA firmware which finally switched the csc to tmb/tmb/att

I then flashed back to the U TMB firmware which now has the proper tmobile bloatware.

I woulda just left the U1 FW w/TMB USERDATA. What's the point of putting the U FW back?

 

[ast11]

didn't know that was a valid option. any downsides either way?

Probably not, but I personally wouldn't want anything even remotely related to AT&T in any phone I own from now on. Loving my F916U1 on T-Mobile with only the necessary TMB stuff (VVM and WiFi Calling) (by flashing TMB USERDATA).

BTW... If you haven't tried Microsoft Launcher, do! Best launcher for a FoldX... Somehow it allows Android Auto to run with normal home screen.

And of course get Good Lock too. Enjoy!

Yes, U1 needs to be flashed first

Any instructions on how you got the CSC to change? And is your phone initially a ATT variant or an unlocked? I have a vzw variant and for the life of me couldn't change it to tmb to gain access to the 5G bands and just yesterday I made the switch to flash Canadian XAC and that actually changed my CSC to XAC/XAC/VZW and now my phone connects to 5G but I'm still missing out on 2 bands for mmwave5G.

Mine's an original F916U1. All I did was put in the T-Mobile SIM and flash TMB USERDATA.
I really don't know what to suggest for your F926xx situation at this point.

@iBowToAndroid ...help?

Hehe all good from everything I've read and investigated it's very hard to switch CSC on a non U1 phone, so I'll be stuck on a Canadian firmware until a work around is discovered

Did someone already get the June update for U1/XAA? (I didn´t. And its not yet on sammobile/frija)
(Just to explain my impatientness: I will have a business-trip in some days, where the eSIM/dualSIM update would be quite nice)

Hmm.. And maybe someone could explain me one thing that I still don´t understand:
If U are the provider version and U1 is the "unlocked and with no carrier bloatware" version. What are the so many U1-fimwares? ATT, TMB, XAA, ..... ? (No bloatware but different optimizations for the provider networks?)

1. It's not out for XAA yet but you can flash any U1 firmware - doesn't have to be XAA

2. Yes, the reason for all the U1 versions is that each one has the Settings preconfigured to different optimizations for the provider networks. The reason that it doesn't matter which one you flash is that the phone will re-configure itself to match whichever SIM you insert

Thank you very much for your answer. Then I´ll try AT&T for now, as I will likely not get any optimizations for my Austrian provider

Anyone received the JUNE update on their FOLD 3 (US version) F926U1 ?
