- Thread starter Electronic Punk

I have the g998u1 with buk7 and don't have scrolling issues nor other issue. I just did update without whipping and all my apps are working fine. Battery seems to be the same as last A11 I had install.

I have look it primarily but it isn't something like just version issue. Something needs to look deeply. Will check sometime later when time permits.
The guy who modded the original hasn't responded to his original thread in a long time. So there isn't much hope he can do same with the one I sent you. But no rush anyway. Last seen August 2020

Do you know if this firmware will work with regular S21 5G (qualcomm)? I'm having a hard time finding a specific thread for the Official S21 Firmware (if you have a link, please share it). --- NOTE: when my S21 updated to Android 12/ OneUI 4.0 about 10 days ago, my phone became extremely unstable and was constantly rebooting. Then a Verizon Security patch was pushed and my phone got to 25% install, then bricked at 'Downloading'. Keep trying to reboot but it goes back to being bricked at 'Downloading'. Not sure if anyone else had that issue...

This thread is for exynos phones with model number G99XB. If you want to look for firmware for your snapdragon phone, you can search through the Frija app by putting in your phone's model number and CSC
This is a very eerie reminder of the first few iterations of A11. Hopefully, it should get better after 2 or 3 iterations...I sincerely hope so...

Don t know what that is but i noticed while wearing wireless headphones in any type of calls(sim, whatsapp, instagram) and that the voice sounds a bit robotic at the end of some of the words spoken by the partner. The issue doesn t come from the headphones bc the sound experience for example when watching yt videos is as awesome as before.
So I have 'Samsung Care' Insurance (Asurion) and they are sending me a new device. However, I want to try to salvage this one so I can copy data and factory wipe before I return it. I tried Frija, using my Model # (SM-G991U) and the CSC (VZW) and it's not finding any Firmware to DL... gives me an error saying there isn't anything. I can't imagine that NO ONE has an official ROM for this device. Any help would be greatly appreciated!!!

I checked both Frija and Sammobile's database and nothing comes up for VZW. Latest firmware on sammobile was AUDB (Android 11 with the May security patch). Maybe nobody's grabbed the FW yet but that's unusual since T-Mobile, Sprint, and other carriers are up to date
I'm looing at their Firmware list now on Sammobile, but I don't see anything for SM-G991U..... I must be blind
UK and other countries are now receiving BUKG update. Still no sign of December update which I think will be late this month as they are still rolling out November updates.

November Update was already available with Android 11 as a base. Maybe we it tomorrow or next week
BUKG arrived in Germany 3 weeks after BUK8. Same thing could happen for the next one.UK and other countries are now receiving BUKG update. Still no sign of December update which I think will be late this month as they are still rolling out November updates.
3 weeks = 17 December
I've done a clean install of BUKG, only restored my contacts, music, video, and a few photos. Everything else I've done manually, see how things go. Curious to see everyone's home screens. Here's mine

11@ EVERYBODY AROUND : ENOUGH OF OFF-TOPIC
If you pay attention, you'll notice that the thread is being heavily derived from its main topic which can result in a heavier cleaning if it continues that way.
PLEASE consider staying ON-TOPIC and let the XDA experience continue to be as joyful as it always was !
Thank you all for your collaboration.

XDA Moderation team.965So I decided to send my S21U to Samsung for a battery replacement, engineers have confirmed battery is draining faster than usual, thus faulty, and is been replaced under warranty
so for anyone who's thinking something doesn't seem right with their battery, get it replaced. -
31In this thread, you can discuss and share the Mega links of new firmwares (OFFICIAL STOCK) for the Galaxy S21 Ultra 5G!
NO CUSTOM ROM's and/or ROOT-talk
How to flash the firmware to your phone:
1. Extract (un-rar) the firmware file (i.e. to folder C:\Odin) ***
2. Download Odin v3.14.4
3. Extract the Odin ZIP file (i.e. to folder C:\Odin)
4. Open Odin
5. Power OFF your S21 Ultra 5G
6. Reboot Phone in Download Mode: Connect USB-cable to your computer. Hold down "Volume up" and "Volume down" at same time. While holding down, connect the USB-cable to your phone. Or use the command "adb reboot-bootloader".
7. Wait until you get a blue sign in Odin
8. Add the firmware files to their designated slots (AP in AP, BL in BL, CP in CP, HOME_CSC in CSC). USERDATA stays EMPTY!
10. Click the start button, sit back and wait few minutes for the device to automatically restart.
*** You can always find the LATEST firmware in message #2

Greetings to all. Just dropped by for a little more "Unsubstantiated Update Claim Game" or UUCG for short, cleaning! Since this appears to be an ongoing matter, I will be happy to just drop by everyday and remove these little buggers with immediate effect in an effort to keep the thread on topic, which is why some of you reported these in the first place.
This way, it will eliminate the reports, and save our Mods, me in particular, extra typing practice, even though I need it!
Cheers to all: Badger50
15For the love of Pete!! Thread cleaned again!Can we PLEASE stop with all the unnecessary back-n-forth with these updates!!!! I keep getting reports from various members about constant OT, griping, whining, this that, he said this he said that, and disrespectful and snarky comments CRAP!! So from now on, if I have to action further reports from members that have been repeatedly warned, I will take up the issue with you regarding XDA Rule #2 for member conduct via PM, which can/may result in disciplinary actions regarding your account.
So Please, keep this thread "ON TOPIC" out of respect for the OP, and for all other XDA members. THANK YOU!!

I've cleaned this thread from all the off-topic posts and flamings; my cleaning included all timezone "discussions", not-firmware or S21U related posts, attempts to moderate the thread and much more. Actually, I must say I cleaned the thread AGAIN after all the attempts of my team mates @Badger50 and @V0latyle - and the expectations I'd to read here that the thread gets automatically cleaned e.g. in the morning simply shows disrespect to moderators by wasting their valuable time that could be much better used.
It finally got too much now! I've notified everybody whose post(s) got deleted i.e. everybody should be aware.
I'm requesting my team mates to inform me about anybody who still continues with this type of posting. In turn I'm going to revoke the members write permissions in this thread, initially temporarily for 2 weeks; however, the member will permanently have read permissions i.e. being inform of any firmwarm update. In case of recurring spamming, I'm gradually increasing the write ban to 4 weeks to eventually become permanently. I hope that this friendly warning helps to now keep the thread focussed. Thanks for your cooperation!
