Development [14.07.21] G998B I Dr.Ketan ROM I OneUI 3.1

Search This thread
I am not sure if this is the right place to ask, but since I am using dr ketans roms for a long time and never encountered this, I will try. I am trying to do a backup via TitaniumBackup and I simply can't copy the folder with files. Seems permission related, I tried some suggestions like chmod 755 via twrp, but it doesn't do the trick. If I copy something into the folder, I can copy those files out, but the files that are made my TitaniumBackup on the device, I can't. It just says "something went wrong"
I've had the same issue some time ago. I'll leave the link to my post with the solution https://forum.xda-developers.com/t/solved-cant-copy-titanium-backup-files-to-pc.4257023/

S21 Ultra is dead, beyond repair. "An error occurred while updating the device software" on the blue download screen. Can't power down..... So, prolly back to Pixel 5 and leave the S21 Ultra for dead ?!

Did you flash the image file?
Sounds like you have missed a crucial step somewhere, never seen this error before.

Thanks for the help. I still can't suss it. I've checked through all ROM settings, and no luck. I can't install goodlock, it says unavailable in my region. I've never used it. And it seems to be quite a recent problem but can't figure out what's causing it at all. Every few hours, AOD disables itself, and I like it all the time, it's maddening. 😔😔
Look for a good-lock that is open in all regions, I have heard it exists. If you cannot find one, you can do what I did:

0. Install Good-lock.
1. Remove SIM cards.
2. Clear Galaxy Store Data and Good-Lock Data.
3. Use a VPN and connect to USA. I connected to Dallas with NORDVPN.
4. Open Good-lock and download the AOD extension.
5. Hopefully, enjoy.

@babyboy3265 and @dr.ketan : ofcourse tried that yesterday eevning, no succes. The process of flashing through Odin halts on flashing the super.img from stock rom. Yep, I tried Freija, Odin etc.

Only thing I'm gonna try: different laptop/PC with different cable (used 2 different cables already yesterday eevning). I'll keep you updated on how's developing.

@babyboy3265: I'v been customizing the phones I had every time untill now. Never had this error before, 1st timer for me too.

[edit] Succes! Back @ stock. Used PC, other cable [/edit]

New update? What?

I want to use all bandwidth of Internet connections.

Is it possible?
Yes, currently we are running Ketan R06 which is based on the AUF2 update. But now they just released the AUF6 which according to what I just read has some further performance improvements.

Let's see when the Doc. will find time for the R07.

And what do you mean you want the bandwidth of all internet connections? Like, do you want to unite the wifi and mobile data and to max out on speeds?

It's complex thing. Answer depends on why you want to restore and your current setup.
Routinely, we do needs boot,recovery,super,optics and data
Now suppose you have messed up something in system, restoring super is fine. In case you have something weird in data (usually happens while you playing with lot setting/third party user app etc and got messed up) - Here restoring data is fine.
In case you want to move on previous version of ROM, restore everything, boot,recovery,super,data,optics + Bootloader and modem of previous ROM. Here again a catch, sometimes, samsung blocks downgrading BL and Modem, in that case you can't move.
So, backup Boot,Recovery,Optics,super,Data and restore according your needs.
Thx for your answer. i have now backup with follow options: Boot,Recovery,Data,modem,optics,Optics Image,Super

Is this Setting Okay? I only want to have this backup for security reasons if I change something and then something no longer works as it should.

Right? They just can't understand... So many people from so many countries and different languages and most ask for help and supply with supportive stuff in their own language. Like we are all obliged to speak everyone's languages..
Okay... my bad. Since i'm not with G998B and there isn't one G9980 custom rom here, I'll keep it myself then ,thanks for the time.

Nice to know!

Yes. I did this with my old venerable Samsung Galaxy S7.

If same csc doesn't get update (uf2 to uf6) then there is no any extra fix but similar update for different csc and need not to update base. Probably within a wk or 10 days,there may be a July update. I don't find any reason to update UF6
Believe me, regarding battery there is nothing better than already you applied wakelock fix. Even UF6 still have those f* wakelock and draining.

I fiddled with the config, now SafetyNet attestation NO longer pass.

I wanted some extra features, such as autoredial. It works, but the system crashed a couple times.

I want to "discover" the secrets of S21u and get the maximum features, but I suspect I need to find a different approach.

Now the bank app crashes, for example :(

Any way to fix it without need to reflash? Thanks a lot in advance and sorry. I used SetEdit app, I exported the config as a json file (only format available). I can't import files, unfortunately.

Dark Mode gets eventually disabled, no idea why as I configured it even in developer options too. I want it always, I even prefer Unix terminal style (green foreground, black background) but better this than nothing.

Any hopes for a custom kernel based on latest ones? What's the status of GPU drivers and drivers for other stuff in this mobile?

    You can't move the file due to its size. Transfer it via a different ROM.

    It's 5 min job to create twrp flashable zip for bootloader and modem, but it always carry high risk of bricking device. If bootloader file is corrupted, and suppose you flash using twrp, your device will hard brick and only way is to replace mobo
    That's the reason, I never provide twrp flashable bootloader. My bootloader files always comes in md5, so in case you have corrupt Download, odin will failed to flash to protect your device.
    So, in sort never expect twrp flashable bootloader by me.

    How?
    Doesn't work for me. I'm on latest R07, using LSposed Magisk module and that seems to have broken the SafetyNet.
    I have tested LSposed yday for other purpose and safetynet passing with it too. Also GooglePay working fine here too.
    Regarding your old query about, dual message screen bootloop is newly implemented security since A11. As of now only Pro version have experimental fix.
