Hi all,
I've been trying to root my A505FN all day with the help of various guides but everytime Magisk starts up via Recovery method I get a bootloop. It starts up the startup wizard, then 10 seconds later reboots.
I have flashed a stock Android 10 firmware on it with BIT5 - A505FNXXS5BTLA - all working fine.
Took the AP file, and pushed it to the device, and stripped the .md5 off the end.
Installed Magisk.
Patched the AP file using Magisk App, and the log looked ok and said -patched recovery.img
Pulled the magisk_patched.tar file
Put the magisk_patched file into AP slot on ODIN, and added other .tar.md5 files as normal. Unchecked Auto-reboot
Flashed successfully, rebooted myself, and then held the recovery buttons to enter recovery to do factory reset
Rebooted again and held recovery buttons to the OEM unlock splash screen and then let go.
Boots up fine, but then 10 seconds later, reboot, can't even get past Wi-fi setup.
Any ideas? Thanks
Trying this again and flashing multidisabler, that could be the issue. If that still fails I'll be using OrangeFox and trying that method.
OrangeFox Recovery method worked with the following
- recovery sequence is Vol Up + Power button
- to get to download, from a powered off state, press Vol Up + Vol Down and plug in cable
- to get back to rooted/Magisk state, I have found the following works better
- power on device, you will see Samsung startup A50 'Secured by Knox screen'
- you then need to press power button to continue booting
- you then see Samsung startup 'secured by knox' screen again.
- once you see JUST the Samsung logo with black screen, now press Vol Up + Power
- seems to boot to rooted state with no issue

I purchased a used Samsung Galaxy Tab S 10.5 on ebay. Originally it had Android 4.4.2
When I turned it on the device is in retail demo mode.
I have tried the following
1) passwords found on this forum such as (5444, M729Q16K8546, blue, unlimited, easy, galaxy)
2) none of these worked
3) Can not deselect "samsung retail mode" in settings/security/administrators
I tried updating to android 6.0.1 by doing the following but the retail mode is still there
It will not enter into download mode so I did the following
1) Enabled developer options on tablet
2) Used command "adb reboot download"
3) Installed Android 6.0.1 stock rom (T800XXU1CPH7_T800XAR1CPH4_XAR.zip) from sammobile.com
4) Tablet installed and updated Android
5) Retail mode is still there and I still can not get rid of it
Any suggestions are greatly appreciated
Thanks
Never had a retail demo device so my answer may be limited.
Did you tried/are able to install TWRP ?
If you can get TWRP you can try to make a complete factory wipe (Advanced Wipe > check all the boxes > wipe)
Then reboot to download mode (Reboot > Download)
Install the stock rom again
Here is the link: https://forum.xda-developers.com/ga...p-2-8-6-1-unofficial-sm-t800-805-807-t3074633
Flash it via odin
I have tried to do TWRP but can not get it to work. I did not use the apk I was using ODIN on my pc. I was using a TWRP file twrp_3.0.0-0_T800. Not sure if that was the issue or not.
Here are the steps I used:
1) put phone into download mode by using adb on pc (adb reboot download)
2) In ODIN
a) turn off autop reboot
b) select AP file twrp_3.0.0-0_T800
c) wait for success in ODIN
3) tablet never rebooted so I used these keys (press at same time until reboot power+vol down+vol up+home)
4) Tablet rebooted into normal running mode
If you don't enter in recovery right away you flash it the system will revert the changes back. so if the system start to boot normally you need to flash via odin again.
I recommend you to flash the version i linked, as it is more compatible with MM bootloader, also turning off auto reboot is a very important thing.
You need to press all the buttons together power+vol down+vol up+home, (press power last) . when the screen light up release the volume up button (the next to power button) and keep holding the rest.
also...
You can try one trick that i use sometimes, it will give you more time to make the key combination, connect the device to the charger and press and hold power+vol up until the screen turn off, it may show a battery icon, so you disconnect the charger and wait the icon go away. the device should be turned off now. so you basically press and hold vol down+home+power (press power last)
If you done the combination correctly and the screen became black, don't worry, it is a bug, just wait some time (1 min i think) and press home key, it should show the recovery.
It can be a pain in the a** sometimes... but trust me, it generally works.
Ok, so far so good. It took a while but I got into TWRP. But I can't seem to select the image file.
I have it on an external MicroSD in the root. File is called T800XXU1CPH7_T800XAR1CPH4_XAR.zip
I can browse files on the list on the left. But I can't seem to find the file
Did I miss a step?
Somehow after going through menus, it recognized the file
But when I tried to install it, I got these errors
Zip Signature verification failed!
Error installing zip file /sdcard/download/T800XXU1CPH7_T800ZXAR1CPH4_XAR.zip
Could not find 'META-INF/com/google/android/update-binary' in zip file
Error installing zip file /sdcard/download/T800XXU1CPH7_T800ZXAR1CPH4_XAR.zip
you got me wrong, in the TWRP what you need to do is make a complete wipe (Wipe > Advanced Wipe > check all the boxes > wipe)
then you need to enter in download mode. (Reboot > Download)
and flash the rom via odin!
extract the zip on your pc, it should be a .Tar file, select AP mode on odin, select the .tar and flash it in there.
I apologize for the confusion. Those steps worked!!
I think part of the problem is that I did not extract the firmware file. I kept trying to flash the TAR file.
I did a wipe in TWRP
Then rebooted into download mode
Flashed extracted firmware file in ODIN in AP Box
Then the tablet rebooted and was in setup mode like a brand new tablet!! Who hoo.
Works great
Thanks for all the help

You have to downgrade magisk to the version 19.3 because the TWRP is patched with magisk 20.1 (unusable version for the a50)
is there a compatible version of TWRP for the new released Android 10 A50 update yet?

I am not responsible for any damage to your device, when you root you lose the Warranty
This guide collects A107F development info, but with the files ported to the A107M.
Thanks to the Galaxy A10s Development team for the original files.
You need to be on Android 10, if you are on android 11, there are tutorials to downgrade.
[BootLoader Unlock]
- Backup all your media, this process will delete your internal media including music and photos
- Go to developer settings and enable [OEM Unlock]
- Reboot to download mode (Turn off, press VOL- & VOL+ and connect the USB)
- When prompted, press and hold VOL + to enter bootloader unlock mode
- Press VOL + to confirm you want to unlock bootloader, this will wipe your data
- If you think the bootloader is fully unlocked, it is actually not! Samsung introduced VaultKeeper, meaning the bootloader will still reject any unofficial partitions before VaultKeeper explicitly allows it.
- Go through the initial setup. Skip through all the steps since data will be wiped again later when we flash TWRP and magisk
- Enable developer options, and confirm that the OEM unlocking option exists and is grayed out. This means the VaultKeeper service has unleashed the bootloader. This step is MANDATORY
- Perfect! Your bootloader now accepts unofficial images in download mode.
[Twrp Install]
At this point, you will need to install Odin on your PC.
Bootloader unlocked is OBLIGATORY.
On your MicroSD, put the "A10s-encryption-disabler.zip" file.
Boot to download mode, load "VBMeta" file in AP and "TWRP Ported to A107M" file in BL
- Disable [Auto Reboot] in Odin
- Flash
- Force a reboot by pressing VOL+, VOL - and POWER buttons at the same time
- With the USB connected, and after the screen goes black, IMMEDIATELY let go of all buttons and IMMEDIATELY press and hold VOL+ and POWER button at the same time to boot to TWRP Recovery
NOTE: TWRP on this phone is not perfect, after booting to it, the screen will remain black after the Samsung logo disappears, simply wait 10 seconds and press the power button 2 times to have acces to it.
- After booting to TWRP successfully, go to WIPE in TWRP
- At the bottom, you should see an option to FORMAT DATA. After you select it, you will be asked to type "yes" in your keyboard. If you do not see this, you probably selected the wrong option.
- After formatting data, flash the "A10s-encryption-disabler.zip" with TWRP. This is done to avoid future bootloops.
- Optional, flash "Magisk.zip" if you want to keep on Stock ROM with root.
- After doing this, boot back to system and you are done
- Wait patiently for the device to boot for the first time
[Custom ROMs Install]
Bootloader unlocked and TWRP isntalled are OBLIGATORY.
Most of the GSI ROMs of this forum works fine on this device.
Only download a64 ROMs, do not confuse with ARM64.
On your MicroSD, put the ROM image.
- Boot to TWRP
- Go to Wipe > Advanced
- Wipe ONLY the System partition
- Go to Install
- At the bottom, select option "Install Image"
- Search for your GSI. It should be something that ends in .img. If it ends in .xz instead, you need to extract the image first
- Optional, if you want Root, flash the "Magisk.zip" file
- Go to recovery main menu
- Go to Reboot
- Reboot to Recovery
- After that, go to Wipe and perform a Factory Reset
- Reboot to System and enjoy!
