TWRP recovery not working - Samsung Galaxy S7 Edge Questions and Answers

Boot animation just does on forever after I do a TWRP recovery.
What am I missing?
8.0 Samsung rom with Magisk 18.
Is there another way to backup/restore entire device? with a pc software like odin maybe?

Replacing CWM With TWRP

I am trying to replace CWM with TWRP but not having any luck. I installed GooManager and used the option to install open recovery script, but I still have CWM. So I downloaded the twrp image and used the terminal method
dd if=/mnt/extSdCard/twrp.img of=/dev/block/mmcblk0p34
This completed successfully, but after reboot then reboot into recovery I still have CWM.
I am currently running latest Cyanogenmod Rom.
Why do you want to replace it, anything that TWRP can do better than CWM? If you still want to switch, you should flash TWRP via Odin.
And/or flashing TWRP zip file through CWM recovery
I like the TWRP interface over CWM. I guess I'll try the odin route.
Well I was able to flash a recovery zip file, but now if I attempt to boot into recovery it just stops at the Google Logo (Google edition phone) and I have to pull the battery, boot into download mode and select restart to get out of it.
Just flash the recovery with Odin. Uncheck auto-reboot in Odin. If it doesn't work the first time, flash it 2 times in a row.
I was having a problem with Odin crashing when I attempted to flash. I finally got it working, apparently I had the wrong img file and dd statement. So now everything is working great.
Making Nandroid Backup first thing.

TWRP Auto boot

Helped a friend recently to install custom recover (TWRP v. 2.8.7.1) so she could install a Kit Kat rom, as she doesn't like Lolipop at all.
Anyways, since we did this, TWRP keeps auto booting. Is there any way to disable that and instead boot straight into the system?
your phone its now without os .... so you will get TWRP Auto boot.. try install stock rom then install twrp via odin
We still can boot into the os trough TWRP.
It's just autobooting instead of going straight to the os.

a2017G can't boot after installing twrp (nougat)

After I got my axon 7 it was on android 6 mm. I unlocked the bootloader, then installed twrp. With twrp I tried to flash a bootstack and a nougat. It didn't boot so I flashed stock recovery from twrp and installed official nougat update from there. Now when the phone opens there is that screen says "lock bootloader again, wait 5 seconds phone will boot". Everything is fine and phone really boots but when I try to install twrp again it gets stuck on that screen and doesn't boot in 5 seconds.
So right now:
I have unlocked bootloader and stock recovery
And I am looking for a way to install twrp and nougat rom
Thanks in advance :good::good:

Install TWRP, right after you install it boot to TWRP, format data (check that it formats with ext4) and install Magisk or SuperSU. Your problem may be dm-verity, and magisk or supersu patch the kernel to fix this.
What is weird is that usually if you install TWRP and just boot to system, the system should boot normally, but it should replace TWRP with the stock recovery... This doesn't happen, right?

Because it didn't actually boot, it failed to boot. But it should have booted afaik
Whatever, it works now

TWRP Not working

Hi, I have a essential phone running Oreo 8.1, just recently I have rooted the phone with magisk v16 an twrp 3.2.1, I successfully flashed it with twrp but after the flash whenever I want to get into twrp it just freezes up on the mount data screen and I have to force reboot it, does anyone know a solution to this problem
Make sure you're following the exact steps from this post. Every step is crucial (except #3, because you have to disable your screen lock before booting twrp.
You shouldn't have to manually mount anything in TWRP either. The magisk installer might give you an error about mounting system but it doesn't seem to make any difference.

You cannot have TWRP installed with 8.x.
TWRP is not compatible.
You must flash the original boot image, then install magisk.
TWRP cannot remain.
You will boot loop.
Please read the instructions on rooting carefully.
Ok thank you
Why can't TWRP replace recovery instead of boot?

No one has created a bit image with TWRP as the recovery.

Because the partition layout of the Essential does not have a recovery partition.
Recovery is contained in the boot image.
So to have TWRP resident/permanent, the boot image must be patched.
It has been done for 7.x, but sense 8.x is still beta, there is no official TWRP for Oreo.
Once Oreo is final, I expect we will get a TWRP that works.
The current limitation, means you can't flash without a computer handy.

Boot loop after trying to install an older version of Magisk

I had Magisk 16.0, but Magisk Hide didn't work very well. I wanted to see if it would work with Magisk 14. Not it's stuck in a boot loop. It shows the "Samsung Galaxy S8 powered by android" for a few seconds then reboots. I can still boot into TWRP recovery and access the storage. Download mode works too. I tried uninstalling Magisk and flashing the stock boot image. Neither worked. Is there anhthing I can do to make my phone work again without losing my data?
Update: if I have to flash the stock ROM, I'm planning to do the next thing: back up my data partition to an external hard drive with TWRP. After I flash the ROM and wipe everything, I want to reinstall TWRP and restore that backup. Would this cause any issues?

I think you cant, since your phone is bootlooped there is no way to get your data back ..
You should backup your data even before root your phone ..
Just flash latest TWRP img.tar from odin, disable auto reboot from the options on odin , after the success flash you need to press the buttons to enter recovery mode .
