This will sound extremely stupid but,can anyone do a video of this? im a huge noob,all i saw on youtube was S20FE but when i checked it said exynos and then other type of version like "SM XXXG" so i tough it wouldn't work on my snapdragno 865 SM G781B.

Im not trying to be rude or anything but can you provide us the room already flashed to install with odin?,it's because i tested everything and nothing works,either is magisk that gives me error image.boot or odin showing failed when i try to do this,in fact i don´t understand some words.

Disable encryption:

- Flash multidisabler-samsung-3.x.zip
i don't know what to do there haha,im an extreme noob,rooting for example s5 and j7 was so easy,these are haaard for me,especially when you guys say something like,then you need to disable or decript and not saying like for example,go here,go there,push this and then do this etc,it´s different haha.So,what im i soppose to do there?,the disable encryption,i looked on internet and there´s nothing how to do that,in fact,they show the entire thing and still don't understand it.This is for root right? otherwise im doing everything for nothing haha.

Its a link if you press on it.
And in the same step there is "OR"
You can skip it and do the easy part.

hahaha not that,i meant to say i don't know how to do that part,i know it's a link,i just don't know what it means by Disable encryption and flash that file,i did the rest and no error coming from odin like the other mate said,at least for me no error on odin,but how to do the part of disable encryption and flash that file?

Go to twrp, advanced> terminal
Type multidisabler and press enter
Then format data and type yes to agree.

I manage to go to the recovery mode but it shows the official one,the one that shows black backround and then letters in colors white,red and green,you know,the original recovery mode,it doesn't show the one that shows in the post,the one with gray and blue screen,weird,since i installed everything and didn't show any errors on odin,do you have any clues of why is that happening?.

There´s no way this is true,s20 FE UI4.1 SG781b is not rootable,trust me guys when i say i tried everything and no luck at all,TWRP fails to open even with no errors on odin,the other metods like kingroot,kingo root,iroot and so,everyting shows me that i need wifi bu i do have data to use internet but still doesn't work.

And still i can't root mine,so what is that tell you?.I didn't touched anything of normal use of it,so why TWRP doesn't work?.
after flashing twrp you must boot straight into the recovery and not the system. if the system boots and multidisabler wasn't flashed the stock recovery will be restored.
flash twrp again and start holding volume up and power straight after clicking start in Odin. leave the cable plugged in.

I did everything Mr Burns,and still didn't show it up,what do you guys mean by "flashing"?,because i only use odin as the tutorial said and nothing happen,im just stuck in that part.

I understand now,the thing was that i was pressing power + up a liiiiitle bit too slow,in fact,i notice that when you start flashing TWRP in odin you need to start pressing power + up inmediatly in order to make it work,but also you need to be fast in the menu of "the bootloader is unlocked" by pressing power and then fast hold power again + volume up,at least that worked for me.So,now that i have root,i was locked the bootloader but once you do that the error ! shows up and not letting me enter again,so i needed to start all over again,is there a way to avoid that bootloader unlocked screen and also the "you´re using an unnoficial samsung software?"

    Hi everybody,
    Sorry in advance for this noob question.
    Starting from stock Android12, I went thru all @afaneh92 process and it's working nicely.
    Now I'd like to upgrade to Androi13: do I have to rerun exactly all the process (& so loosing my data)?
    In other words: are BL unlock and avb disable persistent after an Odin flash ?
    Thank you for sharing your skills !
    Note: steps 2-6 are important, missing any will lose your data.

    1. Load all files to their respective slots in odin, pick HOME_CSC instead of CSC.
    2. Uncheck auto reboot in Odin and hit start.
    3. Reboot to download if possible from odin options (not working on all devices), or using buttons combo.
    4. Keep auto reboot unchecked, Flash TWRP in AP slot and vbmeta_disabled.tar in USERDATA
    5. Hold volume down and power until the screen goes black then immediately switch to holding volume up and power to reboot into TWRP.
    6. Disable encryption:
    - Go to Advanced > Terminal, type: multidisabler.
    You will see " - Finished." When it is done.
    7. flash magisk then reboot to system (optional).

    Hi again,
    Some feedback after applying carefully your procedure @afaneh92 : Android13 installed with all features and data preserved :love:
    I'm really impressed by your knowledge. One more time: thank you !

    Thank you for your quick response, I also have the G781B model and was wondering if it would work with android 13. Now that I have the answer, I have another question. I'm also looking forward to installing a custom kernel, (That's why I was wondering if twrp would work with android 13) what would you say is the best custom kernel for my model when it comes to performance and battery because I want a good balance between good battery and good performance. Form what i have collected the best kernal are primekernal, bandido and kimbokernal. So what would you say is the best kernal when it comes to balance between good performance and good battery life?

    Thank you in advance.
    I really dont know what about other kernels, but now I can say that Bandido works pretty well, you can try Prime and tell me what about that cause Im looking for that experience too, sorry ^^

    Wow: that's a quick, clear and detailed answer to all my questions ! :D
    Thank you so much for your great work afaneh92 (y)

    Hi everybody,
    I've got a S20FE SM-G781B snap 5G with Android12 / One UI 4.1.
    Thank to @afaneh92 and many people here, BL unlock, TWRP install and root with Magisk ran perfectly.
    For about 1 month now, Android13/ONE UI 5.0 stock FW is available. As a noob, I have some questions about upgrading my phone:
    1 - We have to upgrade manually with Odin. But do we have to reflash the vbmeta_disable tar file after (or during) FW upgrade ? (guess the FW flash will enable the verified boot check)
    2 - The same way: I imagine that the stock FW flash will overwrite the recovery so we have to reflash TWRP ? May be we can avoid this rebooting on existing TWRP after FW flash and before 1st system boot ?
    Is afaneh92's TWRP Rev. 3.7 compatible with Android13/ONE UI 5.0 ?
    3 - Is root cancelled by the upgrade ?
    As a last question, is there a chance to keep our data thru this procedure ?
    Sorry for this bunch of questions but I prefer prevention to fixing if I do something wrong...
    Thanks guys ! :)

    I have the same doubts about upgrade from android 13 without losing data to the last OTA Android 13 (january) (already downloaded with frija and generated patched AP with magisk GVK6)

    i'm already in Android 13 (previous version from December or so), unlocked and rooted...
    Thanks!


    EDIT:
    Following your steps : All OK

    Using patch AP from magisk method: nevers works for me (bootloop)

    Thanks!

    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.

    Code:
     * Your warranty is now void.
    * I am not responsible for bricked devices, dead SD cards,
    * thermonuclear war, or your getting fired because the alarm app failed. Please
    * do some research if you have any concerns about features included in this ROM
    * before flashing it! YOU are choosing to make these modifications, and if
    * you point the finger at me for messing up your device, I will laugh at you.

    Supported Models:
    Galaxy S20 FE 5G G7810, G781B, G781N, G781U, G781U1, G981W and G780G (4G).

    US/Canada bootloader unlock thread:
    here

    Download & Guide:
    1. Unlock your bootloader.
    2. Download S20 FE 5G: r8q.
    3. Reboot to download mode and flash vbmeta_disabled.tar in AP slot and reboot. Device will reboot to stock recovery mode prompting you to wipe data so wipe data and reboot to download mode again.
    4. Put the TWRP tar for your device with Odin in the AP slot and click start.
    5. Reboot to recovery via recovery key combo.
    6. Disable encryption:
    - Go to Advanced > Terminal, type: multidisabler.​
    If vendor complain about free space left on device, will attempt to resize vendor. and it ask to - Run multidisabler again!.​
    - Type: multidisabler again. will see - Finished. when done.​
    7. Go back to Wipe > Format Data > type yes.
    8. Reboot to recovery.
    9. Flash magisk apk in twrp.
    10. Reboot to system, Enjoy.

    Note:
    To disable encryption manually:
    You need to replace fileencryption=ice with encryptable=ice only in userdata line (maybe rest lines) in vendor/etc/fstab.qcom
    To avoid stock recovery restoration manually:
    Rename system/recovery-from-boot.p to recovery-from-boot.p.bak

    Support:
    Live support is available via #twrp on Freenode with your IRC client or just click this link.

    @afaneh92 just checking in to ask what if any sources to you want / need to help you ?
    I'm on the Samsung open source site now and downloading a zip for G781BXXU2CUD1 but I've no idea if it's kernel sources inside (280mbs ish). another page I saw here mentioned using the inquiry tab to submit a request.

    if you can tell me exactly what you want I'll more than happily put in a request for it, I'm sure others would too.

    I'll edit this later and add the zip files full name that I've downloaded and if you want that I'll put it mediafire or similar.

    SM-G781B_SEA_RR_Opensource.zip is the archive name, taken from clicking on G781BXXU2CUD1 which matches my current baseband and buildnumberView attachment 5299763
    I will start working on the new kernel source soon.

    @QRCode please consider making a thread about the exact method it required, resources needed and your experience with it.
    this sort of thing will be useful to others. particularly of interest is the features that don't work currently.
    I'll do my best still testing everything compiling my data etc
