I odined back to brk2 then recovery the zip to csa7

---------- Post added at 11:43 PM ---------- Previous post was at 11:41 PM ----------

Csa7 is the latest, you don't need to reset. Use the csc not the home csc.
[Samsung Galaxy S9  Guides, News, & Discussion] Juice3250:
Well, this sucks! My credit union app won't work with CSA7 on my S9. Looks like I'll be Odining back.... again. So done with trying the Betas.

---------- Post added at 02:16 AM ---------- Previous post was at 02:02 AM ----------

Maybe I'll just use my bank's website. I just lose access to deposit checks. It's slightly more inconvenient. But it's better than factory resetting back to Oreo.

When I tried to sideload brk2 to csa7 it says it's for starqltesq devices and I have starqlteue.

you have to flash brk2 in Odin then flash csa7 in recovery

hello guys I'm going crazy, I installed Pie yesterday and after having reset it 2 times every time on the sides of the screen appear 2 white bars, if you drag them sometimes open the navigation menu and sometimes

it only makes a small vibration and returns to the main screen , someone knows how to turn them off? thank you https://ibb.co/HnGMLyv

USAA works. Google Pay works. I too have a credit union account and the UI looks exactly like yours, and it doesn't work either. The same pop up comes up and it flashes. I have to force close it to make it stop. Very irritating.

I'm thinking the app isn't compatible with pie. Do you know anyone who banks at your bank and has a different phone running pie? If so, does the app work on their phone?

I've been on CSA7 and have been having issues with Spotify becoming unresponsive or lagging. It's sporadic and usually happens when I use wired headphones. I'm also using the AKG earbuds that came with my S9. Spotify doesn't respond to the play pause button from the lock screen. As soon as I unlock my phone, it will work.

Did you manually put those apps to sleep?? Happened to me when I played Pandora.
[Samsung Galaxy S9  Guides, News, & Discussion] :
I'm still on Oreo and have been having those issues as well. I think it's probably a bug with the app.

Dear brother, is CSA7 a final OTA update or do we have more to receive ? Actually battery isn't that much good aur few glitches.

I've been sitting on CSA5 all this time because the "CSAX" updates seemed to be coming so frequently and I didn't want to find a BRK2 firmware to download since I'd been flashing BRJ6.

If I get BRK2, can I flash it and update to CSA7 in recovery without losing data?
[Samsung Galaxy S9  Guides, News, & Discussion] WuNgUn:
Yeah... Odin your Oreo firmware. Make sure you set no reboot for Odin! If it tries to boot up Oreo, you're toast.

After Odin, reboot into recover and flash your Pie build and you should be golden.
[Samsung Galaxy S9  Guides, News, & Discussion] DildoMaster:
Awesome, thanks. I actually got the BRJ6 to BRK2 update from Firmware Science.

Would I be able Odin BRJ6 then flash BRK2 and CSA7 consectively back to back without rebooting?
[Samsung Galaxy S9  Guides, News, & Discussion] WuNgUn:
Yup...

Should be okay...?

[Samsung Galaxy S9  Guides, News, & Discussion] m1batt1:
Just pick any BRK2 and it will work. I believe I used a T-Mobile variant. The only thing is don't flash the user data portion of the download. Once you boot it'll auto detect carrier based and you'll have a full at&t phone again.

I'm on CSA7 for the Verizon S9. If I wanted to install this, would I need to Odin back to Oreo first then flash this? Or can I flash it from CSA7? I already have BRK2 and the latest Odin on my PC. I would probably need to factory reset, correct?

Is that not a Preview String, And im not questioning anybody saying this is the official as i am using CSAB right now and all is good.

Quick question? What will happen if I have the official pie (csab) on the root of my SD card and am currently on csa7 pie beta and just go straight to recovery and update zip from SD without doing all the Odin back to brk2 stuff?? Wouldn't it work since that's probably what's going to come to tmo users from the last beta anyway? I'm a noob and lazy with PC... I'm on a T-Mobile s9 carrier locked 960u.. the person above me seems like he did the same thing from zrkl or whatever
[Samsung Galaxy S9  Guides, News, & Discussion] moisesmcardona:
I used Odin with my G965U (S9+). The previous update that I had installed was ZRGL. Flashed everything except USERDATA.

At first boot, it said an error about resizing /data, but I just pressed "Reboot now" or something like that and then it booted and everything loaded nicely and without problems, with the same T-Mobile branding.

I didn't did nothing about placing an update.zip in my SD card nor I had to do any additional steps other than loading the firmware files in ODIN and pressing the Start button.

[Samsung Galaxy S9  Guides, News, & Discussion] m1batt1:
It won't work. For one thing the user you're referring to used Odin so it will over write whatever build version was on the phone. If he had flashed via recovery it would've required the starting point of BRK2 otherwise it would fail. As for tmobile users that were on beta, yes they'll get pushed an OTA but only if they were on the official beta program using Zxxx firmware and not Cxxx which were leaks.
