Hold power and vol down for 7 seconds, after device reboot and screen goes black press vol up and power
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
I've unticked auto reboot in odin, when i press vol down and power for 7 seconds the screen goes dark but the phone boots up again. will this work on the july patch ? did sammy change something ?

EDIT: never mind, it's booted into TWRP for me now, the extra screens in the booting process made it more confusing. MANY THANKS!!
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
@afaneh92 I've tried creating backups 4 times now with the latest version twrp-3.5.2_10-4_afaneh92-R-r8q.tar and it's failed all 4 times.

if I download it again would I be able to flash the extracted image from the tar directly from TWRP ?

the only thing I've done with is flash magisk 21.4 zip which worked OK, so I'm wondering if can I take this lazy shortcut ?

I'll try and backup again and ask for logs now that I think about it.

the backup size was 15gigs so that didn't seem quite right already.

EDIT : failed a 5th time to backup, tried twice to internal storage and 3 time to USB OTG.

recovery log isn't uploading here... will keep trying on that.

backup partitions selected were BOOT, DATA, CACHE, EFS and SUPER... I got backup sizes of 14+ 15+ gigabytes on my last two attempts. this doesn't sound right all!

I tried to shortcut reflashing just recovery.img from USB OTG and TWRP could not see the recovery.img... I clicked from flash zip to flash image a few times.

G871BXXU3CUG2 July 1st security patch.

EDIT 2 : recovery log is 5.6 megabytes and not uploading. if you want it I'll put it on an external host.

I had problems last week with restoring my backup from otg. I just remembered. Mohammad helped me. I had to move the location of my backup
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] afaneh92:
I need recovery log.

and make fresh log only backup one time then take the log
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
just took another backup with the intention of getting fresh logs, this time it worked though. I reboot from a root app as I don't like doing key combos, this time once it loaded I put it on charge and rebooted from TWRP into recovery again and reapplied the settings because they didn't stick from the first time I applied them.

I turned off screen timeout. I think it's either the timeout (I've had that on other phones) or how I boot into TWRP. you might know if the timeout thing is still an issue with TWRP.

I can still try more if you want to narrow it down.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] afaneh92:
Yes please try with timeout
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:

it's still getting larger file size wise, 6.1mb backup started about 10 minutes ago with timeout on

I flash twrp but stil I'm able to boot into stock recovery. What am I doing wrong. The flashing is successful.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
you've got to exit download load by making the phone reboot with a long power key press (I think) with the cable out... then quickly switch your grip to instantly try to enter recovery with key and cable combo.

turning off auto reboot in Odin might make it a little easier.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] riddle13:
I'm leaving with volume down and power combo, then volume up and power. Stil stock recovery.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
you've gotta flash again, if you're not quick stock recovery comes back and remains there. don't forget the cable too when going to recovery.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] riddle13:
Ok. I made it but now I cannot accees my external sd car to flash the disabler.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
nope you can't, external SDcard is not visible in TWRP for some reason.

you should always read through a thread before acting on it.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] riddle13:
so where should I put files to flash them through twrp?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] butchieboy:
I use otg
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
yeah a USB OTG is what I used too. if your internal memory is good you could reboot and move the file to internal. not sure but I think it shouldn't be encrypted. @riddle13
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] b1k3rdude:
Same. But no point comping to internal as you may have to format data at some point during the flashing process. Just get an NVME SSD and USB-C external enclosure. Way faster than a regular USB stick.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
yeah I tried backing up to a brand new USB 3.0 thumb drive and TWRP would always fail at the thesuper partition.

I'll probably just backup data, boot and efs in future and flash back to stock first.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] b1k3rdude:
I think its might not like the file format of the USB stick, try doing a format of the stick from the phone and then do a backup. I believe ExFAT is what Android would format it as.

And regarding USB sticks, TWRP dosent like some of them, irespective of file format, so it could just be the stick your using.

Hello,

I have twrp-3.5.2_10-4 on my SM-G781B(Snapdragon). Everythings seems to work greate except access to my Micro SdCard (0MB).

Firmware version G781BXXU4CUH1.

Is there any solution except OTG? OTG works fine.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
no, no solution. the dev doesn't have the phone to work through the issue.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] b1k3rdude:
Hence you back up to OTG storage instead. I can confirm you can do backup and restores on the SM-G781B via all versions upto and including 3.5.2_10-4
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
since I'm here, can anyone confirm whether the latest version works with August and September security updates (some people have September already it seems) ?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] tardoro:
I can confirm that TWRP-3.5.2_10-4 (and backup on OTG) works with August security update.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
I think it's that there's an individual file size limit of 4gb on fat32 and vfat must be the same.

took your advice and formatted to exfat and had zero issues backing up 16gb+

thanks man.

[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
does anyone know what partition must be backed up to ensure your pin number works when you restore ???

got into a situation yesterday where a GSI failed to flash and I restored data because the system was never wiped.

it asked for a pin number but always said my pin was incorrect.

that's a bigger nightmare than it sounds. no pin means you can't turn the phone off. booting into download or recovery is almost impossible. only hearing the windows device disconnected sound helped me know when to switch key combos.

EDIT: I'll just make my backups with fp and pin deactivated I guess.

is this a thing I'm just learning about ?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] butchieboy:
If you have an issue with pin after restore. Boot back to Twrp...then in twrp go to file manger..click system..data..delete the 3 files that have lock screen..reboot then all is good
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
just leaving the pin and fp off before backing up is working OK and less effort.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Svan987:
Hi, finally Magisk rooted on my new SM-G780G (S20FE-4G) and changed CSC from XEC to BTU with Phone info +

I followed those instructions on this video : How to root the Samsung Galaxy S20 series

Don't know why it's written in OP that you need to flash "vbmeta_disabled.tar" in "AP".

From the tutorial it's in "USERDATA" and don't need to press any button after flashing just wait the double reboot to recovery ("Auto Reboot" and "F. Reset Time" enabled in Odin options).

After the reboot in the tutorial he reboots directly to download mode. Me I finished the setup since it was the last factory reset.

I will not install TWRP for the moment since I have trouble to reboot from download mode to recovery.

(I tried also ADB fastboot command with "boot.img" file but it's not working)

Cheers.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
had another night in bootloop hell after another failed attempt at flashing a GSI.

the GSI wasn't the issue, chondoe couldn't see the system.img again and didn't flash anything.

I reflash August, vbmeta and TWRP. flashing multidisabler is where things went down hill. the phone stayed on the Samsung logo so I got into recovery and tried to restore. the restore failed half way through but the phone booted, just without any internal storage.

flashed August again and felt wary to try TWRP again so I patched the AP.tar instead.

is there a reliable way to flash recovery from the phone so I don't risk screwing up root ?

is this version of TWRP really compatible with the August update ?

before I fixed things I think it was magisk that said my phone appeared to be android 16 !!! it was multidisabler.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Svan987:
If you are rooted with magisk I just installed the extracted "recovery.img" with the official TWRP app.

When you start TWRP app. read carefully need to check the first 2 options (one is for the root access).

Then don't bother to select the phone, just select the "recovery.img".

When you got all the trouble like you describe, I recommand you to start from fresh. Odin this official firmware, then answers all the settings without lock features, and reboot with adb in recovery and do a factory reset.

I had to do that after a fresh install with official firmware and odin and when I was in OS I got trouble with WIFI.

The factory reset fixed everything.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
UPDATE: without being 100% sure of the cause i just recreated the exact same issue.

i'd say don't flash the multidisabler AFTER Magisk. i'd like to flash the patched AP but that would wipe out TWRP straight away. so it looks like this is the only way to have both without encryption.

just reflashed stock, and now vbmeta.tar fails to flash. guess i'll flash my patched AP and call it quits.

EDIT: 100% working again.

you CAN flash TWRP over a patched AP and then flash multidisabler and format data.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Svan987:
I was stuck in TWRP impossible to find the zip file. When looking files in internal memory I saw only strange characters. So I created a new directory at the root but impossible to see it too.

Sideload not working. I will restart a fresh install without magisk and try to install TWRP with Odin, to see if it's Magisk messing up something.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Svan987:
I did the mistake to format "data" in TWRP and reboot to recovery to may be fix the strange letters and then reboot the system without flashing the "multidisabler" and It was a big mess no more internal memory.

I got same like you went back to fresh original stock then factory reset and I wasn't able to flash "vbmeta". Was "fail" in Odin. I was thinking to not see the line "OEM unlock" in developpers grey out will not have an impact but it was that. As usual connect to a wifi and set manual date like 1 month earlier. Then you can see the line and be able to flash "vbmeta" again.

Update : For those with OneUI 3.x to enter recovery mode is "Power + volume up" and plug usb cable
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Svan987:
Hi,

Your TWRP not working on S20FE 4G - Snapdragon 865 - SM-G780G

The phone in windows is identified as SM-G781U (S20FE 5G)

So Magisk was not involved.

Thanx if you can fix it.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
@Svan987 I think my mistake was not formatting data directly after flashing multidisabler. that MUST be done to remove the existing encrypted file system. multidisabler turns encryption off but the existing file system is still there.

after a fail in Odin everything you try will fail (did for me) unless you reboot and re-enter download mode.

remember this TWRP wasn't designed for your phone at all. your phone didn't even exist when this TWRP began. it happens that it works on it but it wasn't made for it.

use a USB OTG adaptor with a flash drive to get files into TWRP. TWRP can read OTG connections with no problem, just tap select storage...
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Svan987:
@3mel Do you have the same result like in picture in internal memory before flashing "multidisabler" and formating data ? I read all the post and some users said it was working on SM-G780G. That's why I tried.

Will think if I try USB OTG adaptor and wait if the author is agree to do the 4G version.

@afaneh92 Can you build a TWRP for the 4G version please ? The difference should be minimal.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
@Svan987 this version works fine on the SM-G780G. I meant you shouldn't expect it to be "fixed" to accommodate your phone more.

everyone will have folders and files with scrambled names until they flash multidisabler and format data. if you boot into TWRP before flashing multidisabler your external memory card doesn't work because it just doesn't, your internal memory will be encrypted and useless (for the time being), the only thing you could use is OTG in TWRP.

EDIT: General Observation...

what threw me off the first time was that after flashing multidisabler on a magisk patched system the onscreen log in TWRP says your device appears to be android 16. hopefully that's just down to file system encryption giving bad info.
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Svan987:

September users, is TWRP still working OK there ?
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] Tungstwenty:
I read some info on this thread about keeping data encrypted but still have some doubts. Can you enlighten me on this?

- If I choose to keep encryption on, TWRP won't be able to access individual file contents for backup/restore or even flashing onto the /data partition. But flashing or backup/restore of other partitions is possible with OTG storage.

- Are "full partition" backups of /data itself possible onto an external OTG storage? And working restore of course :)

Apart from these encryption limitations, any known issues with the recent builds of android 11?

(my device is the 4G version (G780F/DS) but there is no big reference in its thread about the encryption implications and the TWRP features should be the same)

Thanks!

if that model number is accurate you're in the wrong thread.

[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] shouk_1987:
Thanks for the details,

So in order for me to summarize and to double check if i understand correctly,

Right now i have Magisk only with the stock recovery ( Filesystem is encrypted normally )

I want to add TWRP without formatting or losing the data and i am accepting to have it working only on USB OTG ( i have a usb type C and type A flash )

I want to have TWRP mainly for bootloop safety precaution ( that can be caused from LSposed or a Magisk module )

Is it possible to Flash TWRP ( suing the userdata in Odin ) along with the same session of Patched Maigsk AP + Home CSC + BL + CP ?

then Enter TWRP and then Flash multidisabler and then reboot to OS and that's it

( from the above i understood that flashing mulitdisabler without format is the source of issues )

If not possible then is there a workaround to Flash same above process but flash Stock AP instead of Magisk patched one then from TWRP flash multidisabler then Magisk ( again without format but the difference this time that multidisabler is flashed over a stock AP )

Thanks for your assistance in advance
[Samsung Galaxy S20 FE ROMs, Kernels, Recoveries, &] 3mel:
if you're already rooted you don't even need to touch Odin or a PC, Flashify or a kernel app with flash capabilities will do for recovery, some people even successfully the old TWRP app to flash recovery.

you could flash TWRP and then multidisabler from TWRP without formatting but as I understand it you might not be able to use TWRP at all because of the encryption still being present.

if you're already rooted get a memory card, a decent root file browser (X-Plore is excellent) and download OAndBackupX via F-Droid. there's only the settings you like to do again, everything else can be moved or backed up.

there's no value in not going the whole way. use the root that you have to backup, then use it to flash the recovery image from that's inside the zip. flash multidisabler and then format JUST DATA. root will still be there once you install magisk manager again, but you might need to update it.
