[Samsung Galaxy Note 10 Questions & Answers] Guerrerobook:
Of course, my intention has always been to have it done by a specialized centre, my need was to know if it was possible, as well as recovering the data from the chip, mounting the memory chip on a new smartphone and making it work as if it were the old smartphone.
[Samsung Galaxy Note 10 Questions & Answers] blackhawk:
Remounting to a new mobo is really not a good plan. You want the data not 2 damaged mobos. There are less steps to go wrong with just a data recovery and flash memory retention is temperature sensitive; the less heating, the better.
[Samsung Galaxy Note 10 Questions & Answers] Guerrerobook:
One of my goals is to recover google authenticator codes. In this case, by recovering a data backup externally, do you think I would be able to recover the google authenticator codes by transferring the backup to another device? Google authenticator only works locally.. i know its a complicated question..
[Samsung Galaxy Note 10 Questions & Answers] alecxs:
may work if google authenticator does not rely on keystore (idk)
[Samsung Galaxy Note 10 Questions & Answers] Guerrerobook:
No, google authenticator is not based on the keystore.. Is a two-factor authentication application that uses a time-based cryptography algorithm (Time-based One-Time Password, TOTP)
[Samsung Galaxy Note 10 Questions & Answers] Network_Pro:
@Guerrerobook What service do you need from Authenticator? I can help you recover the service without the 2FA. PM me for specifics if too private.

What happened with Data recovery and the board heating up problem?

For certain it's an easy conclusion that current leaks happen after the board becomes dirty corroded or components start failing.

Ask the service center that discovered the heat, which part exactly was heating up and at how much voltage? Did they use heat camera, similar method to discover the exact source of heat?

Team Win Recovery Project 3.x, or twrp3 for short, is a custom recovery built with ease of use and customization in mind. Its a fully touch driven user interface no more volume rocker or power buttons to mash. The GUI is also fully XML driven and completely theme-able. You can change just about every aspect of the look and feel.

Data decrypt support should be mandatory for this device expecially with the newer A13 EROFS partitions, please consider adding it.
[Samsung Galaxy S23 Ultra] afaneh92:
I tried on S20+ and S22 ultra it was harder than A series. But will try again when the device delivered, I may ask for your help. Thanks.
[Samsung Galaxy S23 Ultra] BlackMesa123:
Implementing crypto support is not that hard as it seems, in the S23 family it should even be easier since you can just implement the official TeamWin QSEE scripts in your device tree. I imagine the big deal on S20/S22 is due to those device having an Exynos SoC with TEEgris TZ, but even in that case it should be easy to handle. What I'm more afraid of is that this device probably has Knox SDP in vold so decrypt with PIN/password set won't work, but it's better than nothing atm.
[Samsung Galaxy S23 Ultra] afaneh92:
I was referring to snapdragon, and never worked. I used your implementation and device wasn't able to decrypt data. S22 was harder since data wasn't able to mount. I will wait for device, thanks again.
[Samsung Galaxy S23 Ultra] BlackMesa123:
We can surely work it out to fix it😉
[Samsung Galaxy S23 Ultra] BlackMesa123:
@afaneh92 it looks like S23 vold has no crap A11 code leftovers which does break decrypt with PIN/password on TWRP, I compared the vold bin with my A52s' one and certain stuff is clearly missing. So it might just work out of the box once support for it gets added🤔

I hope so.

I followed the steps above, and when trying to reboot to system I get back to to twrp. Help please?
[Samsung Galaxy S23 Ultra] Techguy777:
I just want to ask if anyone has tried installing viper4android yet and does it work? If it's like the s22 ultra and doesn't work. I might sound crazy but I wouldn't buy it. Music is more important to me then spen and camera although admittedly they are good to. It's mind blowing to think 1200 dollar won't sound as good as my Poco f3 or even my lg tribute 10 years ago.
[Samsung Galaxy S23 Ultra] hurray:
I have exactly the same:

- after following all steps one by one there is only a reboot into TWRP itself possible

I compared the steps from this thread with the steps which are successfully working on my Galaxy Tab S8 Ultra ( https://xdaforums.com/t/recovery-unofficial-twrp-for-galaxy-tab-s8-series-snapdragon.4455491/ ) and I see a difference at step 7:

I do not see any "custom kernel" to download in this thread (at least for now) so I think this is the missing part. Or it only works correct in combination with "dr.ketans rom" (which I do not want to use for now).

@afaneh92: Thank you very much for your work (on "root" and also with "twrp")!

Edit: I just read the installation pdf from "dr. ketans rom". There is written in red letters:

So maybe the not booting system is related to the work which the "multidisabler" should do.

I will be happy if there will be some light regarding the non booting system after flashing TWRP.

Maybe I will give "dr. ketans rom" a try and have an eye on this thread how the things go on. :)

________________________________________

@Techguy777: This is very offtopic but I am with you that "Viper4Android" is a very important part also of my daily used tools. I just have found a (for me) good running workaround.

Search the fDroid store for the app "RootlessJamesDSP". Depending on which parts of "Viper4Android" you care about, the app is an extremely good working replacement. In my example, the "Convolver" with the impulse response files are important and that works wonderfully with the players I use.
[Samsung Galaxy S23 Ultra] lcd047:
Sadly flashing "dr.ketans rom" (or the "unroot" one, for that matter) doesn't fix the problem for me. Ironically everything was working fine with "dr.ketans rom" alone, but I just had to try disabling encryption. Well I suppose better is the enemy of good. :(
[Samsung Galaxy S23 Ultra] hurray:
I just flashed the orginal FW from samfw.com and my S23 Ultra is booting correctly into the system. Now I will try the current "S918B_WA6_DrKetan_ROM_T02". It seems that TWRP is build in into the ROM. If this works I will try a backup & restore of user data (this is the most important part from TWRP for me).
[Samsung Galaxy S23 Ultra] dr.ketan:
After flashing my ROM + Format dara (Read changelog) TWRP backup/restore data should work as expected. And for that purpose mentioned in OP
[Samsung Galaxy S23 Ultra] lcd047:
Yup, flashing the full ROM works. Many thanks, and keep up the amazing work!
[Samsung Galaxy S23 Ultra] hurray:
You have convinced me of your ROM. After flashing I had to reformat "data" but afterwards the system booted correctly.

The ROM works very well so far and the additional functions via "ROM Tools S23" are also good (especially that they can be selectively enabled and disabled).

Backup and recovery of user data has also worked flawlessly. :)

So now I can start with the actual setup of all apps.

Thanks a lot for your work!
[Samsung Galaxy S23 Ultra] dr.ketan:
I have seen many users don't want "custom" roms, but my ROM will have complete stock look + single click all critical fix. It won't force users to use customised look. Also it have more options to make modifications in ui but everything will be by user's will.
[Samsung Galaxy S23 Ultra] hurray:
Exaclty this makes your ROM so good! :)

When I first read the manual and the long changelog, it was not so clear to me that the ROM is very close to the original Samsung ROM and that the additional features can only be turned on and off as needed.
[Samsung Galaxy S23 Ultra] patrick1010:
The installation of Dr. Ketan's ROM was quite smooth and it's great that TWRP is included in this ROM. Appreciate the excellent work of everybody involved!

I'm used to make regular TWRP backups so I can always go back to a previous version in case something I did went wrong. Therefore I would need to backup the system, data, and boot partition. However I found that the system partition doesn't show up when I click the Backup button. The TWRP version is: 3.7.0_12-1_afaneh92.

Does anybody could tell me why the system partion is not listed in the TWRP Backup section?
[Samsung Galaxy S23 Ultra] dr.ketan:
It's in super now

Hey @afaneh92 ;

So no R/W access on the S23 , yeah ?

EDIT: Nevermind, Just saw the Bugs at OP

No erofs r/w support yet.

[Samsung Galaxy S23 Ultra] JazonX:
Awesome, I like all the hard work you dropped into this post with links, sources.

Reminds me of my good old days about 10 years back when I used to waste time on the internet correcting people.

Now go check the first post of this thread, and read the part where it says "Supported Models" in Red.
[Samsung Galaxy S23 Ultra] ScottHW:
I'm definitely a 10 years ago kinda guy. Perhaps that article I linked has led me to misunderstand.

I saw the OP here, and assumed that @afaneh92 was starting work with a model that they actually have. I pm'd them to try to clear this up.

It's gonna be a huge **** you to Sammy if this year they used a uniform chipset, and still went out of their way to create extra locks for specific region variants.
[Samsung Galaxy S23 Ultra] JazonX:
It's alright,

and it's best to let afaneh deal with this in his pace as he wishes, as I'm pretty sure he knows what's required - and finding the motivation to pursue it isn't that easy as the revenue from developing kernels are very low. Most days - its just people asking when eta.

Regardless of the chipset, there are other technical factors that define region specific parameters that require some change on some level. I don't think any manufacturer has truly managed to make a unified global phone. It's a challenge we have to live with.

[Samsung Galaxy S23 Ultra] Didiz0:
A little help needed. I’m new here.

Steps:

8. Flash boot_repack.zip (To fix stock recovery restoration) - removes TWRP recovery, right?

9. Flash magisk canary (Optional) - I can’t find any zip magisk canary version which could be flashed via TWRP, I found only .app canary version which is not suitable for flash tho

Any help will be much appreciated. 🙏
[Samsung Galaxy S23 Ultra] afaneh92:
Step 8 to keep twrp on reboot, making it stick.

Step 9 flash magisk apk in twrp, treat it as zip
[Samsung Galaxy S23 Ultra] Didiz0:
When it’s apk it doesn’t show up in the folder.. o.O

Didn’t understood what do you mean about step 8..? I’ve don’t step 8 and after that holding up + power doesn’t boot to recovery anymore
[Samsung Galaxy S23 Ultra] Master255:
I think the S23 Ultra is Samsung's biggest fault. Not only is it a read-only file system and most programs that require SU do not work, even with SU rights, but it also has big problems with the screen, the main camera. And the selfie camera, even officially became worse and has fewer megapixels (and of course it shoots much worse).

I hope the S24 won't be such a failure. Samsung, I believe in you. Don't die.
[Samsung Galaxy S23 Ultra] afaneh92:
need to flash the boot_repack.zip and twrp can handle magisk apk as zip
[Samsung Galaxy S23 Ultra] Didiz0:
Thank you very much! 🙏all good now 👌
[Samsung Galaxy S23 Ultra] Didiz0:
I don't have those problems. S23 Ultra is the best android phone in Europe. Until now they were selling it with Exynos, SD is a totally different story!
[Samsung Galaxy S23 Ultra] Didiz0:
Now when I’m trying to make a backup with TWRP, EFS folder is stating 0MB and can’t be backed up? 😑Any help
[Samsung Galaxy S23 Ultra] Didiz0:
Failed to mount ‘/efs’ (Device or resource busy)
[Samsung Galaxy S23 Ultra] afaneh92:
Ignore it for now
[Samsung Galaxy S23 Ultra] Didiz0:
But how can I make a full backup of my phone without backing up EFS? Is it because for TWRP limitation or there is something wrong with my phone? The strange think is that SIM card is working properly and everything else. Can I proceed with Dr.Ketan ROM without EFS backup?
[Samsung Galaxy S23 Ultra] afaneh92:
Man, just untick it while making a backup.

I will remove it in next build
[Samsung Galaxy S23 Ultra] Mozie:
Which root programs do not work with SU right?
[Samsung Galaxy S23 Ultra] Master255:
All programs that need to change files in the system partition. For example, Adway.
[Samsung Galaxy S23 Ultra] BlackMesa123:
It’s not a Samsung-specific “limit”, that’s how Android handles OS partitions nowadays. Move to systemless alternatives (Magisk modules), they work the same way
[Samsung Galaxy S23 Ultra] Mozie:
Damn.. AdAway is indeed an important program for me.

@BlackMesa123

Do you mean AdAway (or same kind SU programs) will work with Magisk modules at systems that are not R/W?
[Samsung Galaxy S23 Ultra] BlackMesa123:
Magisk has a “Systemless hosts” feature that should add support for AdAway and similar apps.
[Samsung Galaxy S23 Ultra] BlackMesa123:
This bug might be caused by the mount point set in init.recovery.qcom.rc for keymint to work. Unmounting the partition once the data partition is decrypted should fix the issue
[Samsung Galaxy S23 Ultra] Mozie:
Could you try this one 👇 and see if AdAway works with it?
[Samsung Galaxy S23 Ultra] afaneh92:
Yes because we mounted it ro, will fix it later. not a big deal
[Samsung Galaxy S23 Ultra] Master255:
What do I need to check? I've already checked. On my S23 Ultra Adway gets SU rights with Magisk. But nothing works beyond that. The rights are there, but the file does not change.

I was advised to change the host file manually through the Magisk module. But for me, it is easier to go back to the S22 with its Android 12, where Adway works exactly.
[Samsung Galaxy S23 Ultra] Brava27:
Wrong forum. Go back to S22 please
[Samsung Galaxy S23 Ultra] Mozie:
So because this TWRP is not R/W (yet)

are we missing (crucial) things? Or does it do mostly things what it should do?
[Samsung Galaxy S23 Ultra] afaneh92:
TWRP is almost complete, the device is ro and its not TWRP issue.

Also, remember. It's quite fast in the TWRP, you got to answer quickly.

Otherwise the script times out and exits.

If it time outs, just run it again. Volume up is the select key and down the accept key.

Thank you for sharing this, i tried this method on a normal S23 and it works!
[Samsung Galaxy S23 Ultra] elevatorguy:
This TWRP seems different than I'm used too with encryption being a bit wonky. What is the proper procedure to make a backup do I need to erase password/pin before I backup? Then what parts should be selected ? Thanks for the help
[Samsung Galaxy S23 Ultra] afaneh92:
Yes need to remove pass/pin every time you want to use data, or you can use USB OTG

You can backup what you want from the list
[Samsung Galaxy S23 Ultra] elevatorguy:
OK cool one problem down. To make a backup to be able to fix a big f#ck up and just use backup to go back to before I messed up it used to be boot, system, data vendor what would be the equivalent with the new/different options? Do I need to do anything special like mount anything additional? Kinda feeling like an idiot here thanks for answering my questions

Data, boot and super (has system, vendor, product, odm and other logical partitions) and whatever you need extra

[Samsung Galaxy S23 Ultra] Keller0088:
Hey afaneh92, maybe too early to ask. But what are we missing to make custom roms to our device? I come to this question at the moment I entered your github when I was looking for kernel source and device tree.

I have the pc to compile something but not the knowledge.
[Samsung Galaxy S23 Ultra] JohnTheFarm3r:
Both AOSP device trees and a Kernel.
[Samsung Galaxy S23 Ultra] abhijeet715:
i followed these steps. installed twrp and vmbeta disabled, then booted into twrp, then installed boot_repack first and then magisk and rebooted into recovery again. flashed ro2rw and tried booting - where it says on top no os installed. after that it boots into twrp again and shows warning of android rescue party trigger stating reported problem '--reason=fs_manager_mount_all:'

what is wrong here?
[Samsung Galaxy S23 Ultra] JohnTheFarm3r:
Well, your RO2RW most likely failed on you.
[Samsung Galaxy S23 Ultra] abhijeet715:
Went through the whole process of flashing again. Anyhow cant get twrp there. I think the data partition format to keep twrp is necessary? Not sure whats happening
[Samsung Galaxy S23 Ultra] GoJo ^^:
"Decryption will only work if no password/PIN/pattern is set in Android" -- how it is after you install DR.Ketan rom? This TWRP has a password protection feature to compensate when you're not encrypted?
[Samsung Galaxy S23 Ultra] Man1993:
You have a question. My device has painted himself modified ROM, and decrypt the data, but I brush into your this TWRP recovery, reboot into is no problem, but after I restart the system to reboot into recovery becomes back official recovery, not TWRP recovery

Doesnt work for me. patched magisk image and flashed rom. did not flash twrp. but unable to boot the rom... totally stuck on bootloop.. what am i doing wrong here...

Edit - phone booted.. something is really up.. did a lot of things.. first had installed stock rom but with home csc.. then tried booting same issue. bootloop. somehow got into twrp. usb otg was not working for god knows what reason. took a screenshot and in that path copied the magisk uninstall file. uninstalkled magisk and tried stock rom no luck. tried the patched rom no luck. did multiple tries and then again did the same thing and this time flashed twrp with it. tried booting into twrp it went into stock recovery. from stock recovery tried adb sideload still didnt work. then just rebooted phone and it booted. something is really up with samsung
[Samsung Galaxy S23 Ultra] JohnTheFarm3r:
It's CUSTOM stuff, you can't really blame if something doesn't work as you would expect it to while flashing custom binaries and third-party stuff. NO OEM supports this stuff officially.
[Samsung Galaxy S23 Ultra] abhijeet715:
I know that.. its just weird when it did not work multiple times and then it suddenly worked.. whereas used this same process of flashing always.. still. anyhow seems to be solved for now so i am releived and good to go... making a backup immediately and to be on safe side from next time onwards will always have a backup in place
[Samsung Galaxy S23 Ultra] JohnTheFarm3r:
Well, you're flashing the AP instead of just sideloading the magisk directly in TWRP, there lies your first mistake already.
