Instructions
How to install TWRP using ODIN
1) Go to Settings » About phone » and tap “Build number” seven times to enable “Developer options”.
2) Go back to the main Settings page, scroll to bottom and select“Developer options” from there.
3) Under Developer options, look for “Enable OEM unlock” checkbox/toggle and make sure you check it or turn it ON. If the checkbox does not exist, you can skip this step.
4) Now boot your Samsung Android device into Download mode. To do so follow the steps below:
5) Switch off your device.
6) Press and hold “Home + Power + Volume down” buttons for a few seconds until you see a warning screen.
Press Volume Up on the warning screen to accept it and boot into Download mode.
Once your device is in download mode, connect it to the PC with a USB cable. The Odin will automatically detect the device and show an “Added!!” message. If not your device is not connected properly.
7) Now click on the AP tab on Odin window and select the TWRP recovery .tar file that you downloaded for your device.
8) Uncheck auto reboot in the options tab.
9) Click the Start button on Odin to start flashing and wait for it to finish the process.
Once it finished successfully, a pass message on the Odin screen will pop up.
Now you can disconnect your device. Reboot the device by pressing volume down + power + home.
When the screen goes black, press volume up, power and home to get into TWRP recovery.
Done! TWRP is now installed on your device.

There are two versions of the Samsung Galaxy Tab A 9.7. One without pen and one with s-pen.
SM-T550 = no pen.
SM-P550 = s-pen.

I stand corrected/informed now. I hadn't come across this version in stores before. I was under the impression that only WiFi & LTE/WiFi versions were available.

Hey @virsys, if you have time can you please create a twrp also for the sm-t555 (gt510lte). @ashyx also built a working one a few years ago, but it's not updated.
I'm not able to build/update one due to lack of skills and i don't really feel to f**k up my device trying to do that.
Here's the link of ashyx with the devicetree: https://github.com/ashyx/TWRP_Samsung_gt510lte
Thanks in advance,
Cheers,

Hello!
I'm trying to upgrade TWRP on my SM-T550, from 3.6.2_9-0 to the (current) latest 3.7.0_9-0 (from https://eu.dl.twrp.me/gt510wifi/).
However, when trying to flash twrp-3.7.0_9-0-gt510wifi.img from TWRP, I get the following error message:
Size of image is larger than target device
Am I doing something wrong?
FWIW, this tablet is running LineageOS 19.1 from https://forum.xda-developers.com/t/...-for-galaxy-tab-a-sm-t550-dec-9-2022.4479347/

There's a reason my FAQ states that you MUST use a certain version of TWRP when using my roms/builds. More details already written at
https://forum.xda-developers.com/t/...or-sm-t810-dec-12-2022.4430349/#post-86745013
Again, even though it's on the official TWRP site doesn't mean it's been tested or code is maintained and kept up to date.
As newer version of TWRP add more functionality and get more code bloat, the recovery size will get bigger and may not fit the recovery partition. There are ways to minimise the rom size, but the maintainer has to make those changes, test and submit them to TWRP github.

Thanks @retiredtab for explaining why it is necessary to stick with your recommended TWRP version, and not the latest official one.

Why is it possible that there are many newer Versions at
Download TWRP for gt510wifi
Download TWRP Open Recovery for gt510wifi
eu.dl.twrp.me
At https://eu.dl.twrp.me/gt510wifi/, there is linked this thread.
So if maintainer has changed, is there a reason why the link has not been updated?
@ maintainer (virsys??)
- would you be so kindly and update the recovery according to this:
[CLOSED][RECOVERY] [TWRP] Fix • Backup Internal Storage • backup option
O B S O L E T E Fix for • Backup Internal Storage • backup option Universal TWRP Bind Mount Enabler It is a well known fact that TWRP Backup does did not include Internal Storage aka /storage/emulated/0 If you ever wonder how to backup...
forum.xda-developers.com
- shrink your recovery as described from retiredtab to make it working with his custom-rom
Thanks.

official TWRP releases are auto-generated even if maintainer is absent. (actually you can patch your fstab yourself in 5 minutes, just unpack twrp.img, add the line /storage... repack and flash. it's so simple it's not even worth a guide.)
as for the file size.. well IMHO this a big failure not including some file size check according to partition size. reminds me on the days of clockworkmod recovery. should be fixed in build bot ASAP, consequently not releasing new versions without maintenance.

wait... file size is 15 MB so this can't be true? partition should have at least 32/64 MB nowadays.
did you repartition whole phone with LineageOS or something?

I think so. I am not sure.
I am using LOS 18 unoffical from retiredtab.
When I installed this image the first time, I set the tick at "install LOS-Recovery".
This was a mistake. So I installed TWRP 3.6 from this thread.
Is it possible to change partition sizes without flashing any Partition? How?

---

do you have the same warning?
Size of image is larger than target device
@Leonniar had similar issue
Leonniar said:
When trying to flash boot and the patched .img I get:
Code:
fastboot: error: boot partition is smaller than boot image
Click to expand...
Click to collapse
turned out it was just issue with length of file name, not actually partition itself...
Leonniar said:
I fixed it by shortening the name of the file from: magisk_patched_[random_strings].img to magisk_boot.img

Hi! I have a question, I have a Samsung tablet with the model SM-P555M, can this recovery work without problems? I want to install the official Samsung ROM that comes with Android Nougat
