G781B stock recovery always erase TWRP recovery - Samsung Galaxy S20 FE Questions & Answers

Hi there,
I have 2 stange problems. I m trying to root my device following those steps below
Root Samsung Galaxy S20 FE 5G SM-G7810/B/N/U/U1/W Android 10 using TWRP and Magisk
Unlike other mobile manufacturers, Samsung mostly uses two processors in its mobiles. Exynos processor is for International variants and Snapdragon
www.androidinfotech.com
Problem 1 : I manage to succed all the step but i do have pb with TWRP as i can flash it and use it but if i boot on the rom, it will erase it and piut back the stock recovery. So each times i want to use it i have to flash it.
Problem 2 : Then inside TWRP recovery i cant read my sd card ...
Here are the last steps i cant manage :
Now it Will Boot into TWRP Recovery Mode. ok
Select Wipe->Advance Wipe->Select Cache and User Data. ok
Return to Home of TWRP select Install. ok
Select multidisabler-Samsung-2.6a.zip. cant go there because it cant read the sd card
Return to Home of TWRP select Install.

Any ideas?

xiaomi mi 8 bootloop

Hello,
I bought a mi8 with open bootloader and tried to install xiamoi.eu rom. Now I'm stuck in the 'powered by android' boot screen.
How I installed the rom:
1. installed TWRP_dipper via fastboot
2. wiped the phone
3. Copied this 'xiaomi.eu_multi_MI8_V10.2.2.0.PEACNXM_v10-9.zp' to the internal storage
4. Installed the rom
I can't access the TWRP menu anymore. If i try to start it, I get to the 'powered by android' bootloop screen. I've already tried flashing twrp again.
**Edit: I installed a newer twrp version and can now start it***
***Edit 2: Had to "format data" not just wipe, and confirm format with "yes".***
thanks for help.
Hope I have no Brick now

Their is only one way to recover your phone just follow this step
1. Flash stock firmware(stock rom) vie fastboot using MI Flasher
this is bring back you phone and if you want to install custom rom then follow this
1. boot twrp
2. wipe all the data from slot A and B partition(internal storage as per you choice )
3. boot to slot B and copy past the custom rom file in slot B
4. flash that rom and boot to slot B and then flash Gaaps and other staff you want
5. reboot and enjoy.
NOTE: changing the slot require reboot twrp in simple words every time you change the slot you have to reboot the phone and boot again to twrp..
i hope this will work for you..:good:
If you don't have stock flash file then try from step 2. see whether it will work or not otherwise follow from beginning.
facing the same issue
i tried the same and getting the same error. even the twrp3.2.3.0 never worked while tried to flash that one more than 20 times, after flashing 3.2.3.0 my phone either boots normally or it gets completely power off. and if i try to boot into recovery using volume keys and power key , it boots in stock recovery. please help
Mine its ok now... i don´t know whats happen but suddenly it flash withou any problem.
See if it helps...
Make sure you're running a proper working Recovery
Flashing instructions:
Dirty flash (assuming you have rom on slot A):
1. Download all required files and place them to internal memory (ROM, twrp installer, gapps, magisk, ..)
2. Boot twrp to slot B and flash ROM and twrp installer
3. Reboot twrp to slot A and flash gapps (optional magisk)
4. Now reboot to system
Clean flash (assuming you have rom on slot A):
1. Download all required files and place them to internal memory (ROM, twrp installer, gapps, magisk, ..)
2. Boot twrp to A slot and wipe everything except for internal
3. Reboot twrp to B slot and flash ROM and twrp installer
4. Reboot twrp to slot A and flash gapps (optional magisk)
5. Now reboot to system
If you are coming from stock:
1. Download latest TWRP installer and image
2. Open cmd and type fastboot boot twrp.img (change twrp to its actual name)
3. You should be on slot A in twrp, if not change it and reboot to bootloader and repeat step 2.
4. Format data
5. Now follow instruction for clean flash

I have this issue and none of the steps worked.
I got my device 2 days back and it was in Oreo. I tried to update to pie but the update keep failing. I unlocked the phone and flash latest official fastboot rom using mi_flash and installed magisk using this guide:
https://forum.xda-developers.com/mi-a2/how-to/unlock-bootloader-n-root-magisk-easy-t3856800
Everything went smooth.
Today I tried to go further and instal PE rom using this guide:
https://forum.xda-developers.com/mi-a2/how-to/guide-how-to-flash-custom-roms-stuff-t3876375
Everything goes smooth until I boot to TWRP and try to flash the rom. It gave the error posted by OP. I have tried the following things since:
1. Try another two roms, same issue
2. Flash stock Pie using mi_flash then temp boot to TWRP latest version from 'a' partition, wipe everything, then boot from 'b' partition, wipe everything, try to flash. Same issue.
3. Install TWRP (it installed without any issue), reboot to installed TWRP, flash rom, same issue.
4. Try to flash with 'a' as active. Same issue.
5. All other possible combos (i think) of the above. In all cases everything goes as expected until I try to flash the rom.
Currently I have flashed the factory image back. Any help will be greatly appreciated.

Update to DP4 from Official 9.5.11 with root and without data loss

Tried and tested method to update to DP4 with twrp and root working.
If you update to DP4 directly before installing twrp you will be stuck without twrp.
You need USB pendrive and otg for it.
Steps
1. Update your phone to latest available official version.
2. Boot to fastboot and install TWRP (of course you need boot loader unlocked)
3. Flash DP4 from Thumbrive (keep it in external storage only)
4. Flash Recivery TWRP.zip from thumb drive
5. Reboot recovery
5. Flash DP4 again followed by Twrp.zip
6. Reboot recovery and flash magisk and any other mods you need.
7. Reboot
If you followed every steps correctly you will have working TWRP and root on DP4.
I am using it since DP2 and never had issues.
Note. Since Q diesnt allow twrp to read internal storage you will need usb drive for flashing mod also.
I have uploaded a video with DP4 Features if you want to know about its features.
New features
1. Volte working
2. Names of themes changed
3. System UI settings changed
4. Fingerprint faster
5. Overall phone is faster now.
Removed google assistant swipe shortcut.

You need to use msm tool for reverting to stock
Or Stock reset rom for downgrade.
Then follow my steps
Is there any way to downgrade without MSM tool? I have a Mac. Local update doesn't work. Thanks for the reply.
Try MP version from DP Version package via local upgrade.
This will be available once the official thread is created by oneplus.
Or you may try DP to MP version for DP3

I just used the stock firmware .img file via fastboot. I restored 9.5.7 with no issues. Of course you'll lose all your data.

I was able to install twrp and magisk on dp3, i think you can do it with dp4 aswell.
I just fastboot flash boot twrp.img , it says slot a ok, slot b fail.
So i switched active slots and reboot, which boots to twrp installed on other slot. While in twrp (which cannot access data) i installed twrp through adb, switched active slot and installed twrp again. Same for magisk 19.4 installer.
After installing twrp and magisk to both slots i switched active to B and rebooted, which took me to rooted dp4.
Hope that made any sense
Oh and while in twrp, i used twrp installer (latest) to install twrp to both slots.
why do you possibly need to flash the rom and twrp TWICE? shouldn't the usual upgrade process for a rom if you are already rooted still work?
Flash the Q rom
flash twrp
reboot to recovery
flash magisk?
don't understand the reason to flash both twrp and the rom 2 times as posted in the instructions
regardless, i followed the exact steps and it didn't work for me. i boot to a plain black screen and can't get past it. any ideas?

Repeating the steps twice installs the ROM to both system slots

Can you elaborate on step 2? Do we flash twrp.zip the same as the other steps? or do we flash the twrp-installer?
1. Downloaded the 9.5.11 update from Oxygen Updater (DONT REBOOT)
2. Went to Settings\System\System Update and click on the wheel on upper right corner.
3. Select Local Upgrade, then install the update (DONT REBOOT)
*DO NOT REBOOT after applying the update.
4. Remove Magisk modules that may cause problems (Call Recording is one of them)
5. Launch Magisk, and click the first "install"
6. Choose the "Install to inactive slot (OTA)" option
7. Reboot once completed
8. Download TWRP (from another location) and then go into Magisk and install it, but ***DO NOT REBOOT!!***
9. Install Magisk again. Click Install, then select "Direct Install" option.
10. Reboot
Will this work for DP4 as well????

Downgrade using the rollback package, when I did it on Beta 3 it did not relock my bootloader.

I don't think so - what I've read on Oneplus page, when you hit restart (after installing magisk) it will reboot and during that erase all data. then reboot again to system. So you cannot restart via system updater,, you need use TWRP to flash it, so i would stick to the 1st post instructions (including 2-times install t ocover both slots). But hey, ican be wrong, you can try and let us know, it would be easier for sure
Is this the only way to get root on DP4?
Simple way
Info for TMobile gm1915 on 9.5.11
You must have magisk installed.
Update through local upgrade method and don't reboot. Then go to magisk select modules hit + and find twrp installer install twrp and then choose install magisk choose install to inactive slot. Then reboot.
Data does not get wiped but fingerprints need to be added again.
Also twrp decryption does not work so best to keep otg USB with you with whatever you may want to flash.
You don't have to flash to both slots it's not necessary but do as you wish.

Hi, I followed all the steps in OP and didnt. using latest twrp and magisk 19.3 (stable)
Now my phone is still starting its first boot about 15 minutes.
Update:
Probably the problem: installed magisk modules.
Anyway after some research default twrp is'nt mounfing local storage. The latest custom TWRP is! So no issues with USB Anymore, just use local storage like u used to do! This is actualy the only way to use the Magisk uninstaller because you need to mount data for uninstalling magisk modules.

Anyway it took me a view hours of testing but now it works smooth! ?

Proper Upgrade/Flash Firmware

Hello,
I recently wiped my device to start from scratch as in no os. I went into TWRP then wipe and advanced and deleted each option available. Then I downloaded the latest raw firmware I could find which was WW_ZS661KS_18.0410.2108.158_M3.35.19.17-ASUS_1.1.5_Phone-user.raw.zip. After doing a flash_all I obviously wasn't on the latest version of firmware so here is where I get stuck. In order to avoid encrypting the data partition what am I supposed to do to properly upgrade before root? What I ended up doing was;
1. Flash latest RAW firmware
2. Boot into recovery and factory reset
3. Boot into OS, go through basic setup until the home screen
4. Copy latest firmware from ASUS website (WW-18.0410.2203.201) to internal data partition on phone
5. Flash TWRP
6. Boot into TWRP and flash latest firmware
7. Boot to B partition
8. Reboot into recovery and flash firmware again
9. Boot back to A parition
10. Flash twrp on A and B
Is that correct or should I be doing a factory reset / full wipe somewhere in there as well?
Thanks
Why not simply wipe and flash the version of the official firmware you're lookin for with TWRP OR RAW flash flash and upgrade the normal way. And then root. Looks like a lot of unnecessary steps...

Hi I would like to change the version of my phone
How can I do this?
You need to have unlocked Bootloader, there are instructions on official Motorola website, then go to official TWRP site to download TWRP for Moto g7 play, and then put your phone on fastboot mode, unlock bootloader and then boot TWRP (do not flash it), then with your phone connected, put your ROM file into your SD Card (not internal storage) and flash it, after or before that, put some GApps package (Arm64) into your SD Card and then reboot your phone into Recovery mode since most Custom ROMs do install an custom Recovery, there, flash GApps, do an factory reset and reboot your phone, you will have an Custom ROM installed
But i don't recommend it since Arm64 ROMs do give constant app restarting since this is an 2 GB RAM device and new Android versions do consume a lot of RAM
