PLEASE BEFORE YOU decide to try this rom, you MUST read all of post 1 and 2 (about 3 minute read). If you think this is an unreasonable request, then stop reading now and find another recovery. Thank you.
I am not responsible for lost data, identity theft, lost money, security vulnerabilities, bricked devices or any other hardware or software malfunctions that comes as a result of flashing this software.

Installation Instructions
Note I do NOT run Windows OS so there are no provided instructions on how to install TWRP using Windows. There's lots of tutorials and videos online on how to install TWRP via Windows. Do your own research. If this is unreasonable to you, don't use this TWRP. Questions regarding how to install TWRP using Windows/odin will go unanswered.
You need to boot the SM-T357W into download mode. Power off. Press home button + power + volume down (farthest away from power button) at the same time. Let go when you see "Warning" text on the screen, then choose volume up to continue. Your screen should now show "Downloading... Do not turn off target"
Linux users can use heimdall to flash this recovery. For example,
Code:
heimdall flash --RECOVERY TWRP_3.5.2_9_SM-T357W_20220125_Unofficial.img
After flashing the recovery image, you must boot into recovery immediately (using the hardware key combination) to run TWRP, otherwise the Samsung software will overwrite TWRP and you will have to start over again. I usually am already pressing the recovery hardware key combination while the recovery image is being flashed. The flash process will be very quick (a few seconds at most).
The recovery hardware key combination is home button + power + volume up (volume up is closest to the power button) all pressed at the same time.
Updates
Unless Android 12 or LineageOS 19.0 requires some mandatory changes to TWRP, this will be the only TWRP build I make for the forseeable future. There will be no planned updates to 3.5 unless there's a major bug or security vulnerability. The only time you need to boot into TWRP is to upgrade the custom rom.
I have been using this TWRP now for almost 2 months before sharing it here.

[Q] GTablet hangs on recovery mode

When I try to start my buddy's G tab in recovery mode (power button + volume up), it hangs on the "bird screen" / recovery key detected screen. The only way out is to manually shut it down with the power button.
The first time I started it in recovery I was attempting to install CWM, and the Android recovery screen came up. I couldn't get it to take any commands with home button or any other, so I shut it down manually and tried again. That's when it stopped giving me anything.
Mine didn't act that way ... did I do something wrong, or has VS changed something in their latest updates?

NV-Flash your device back to a stock firmware and try again. Or you can just NV-Flash a new recovery file. That would also work.
If the stock recovery had a menu that you were trying to select a command from then the device has a ROM based on the 1.2 bootloader and there are a few things you should know.
1) The home key doesn't activate the selected command. It toggles the display. The power key activates the commands.
2) The standard CWM for 1.1 based ROMs doesn't work with 1.2 based ROMs
3) If the device has one of Roebeet's custom 1.2 based ROMs then you can use the built in recovery pack to flash between Stock Recovery and ClockworkMod with a simple command line script. It may even work to recover from the situation you're in now.

Many thanks. I've learned tonight that his tablet has the new 4349 build, and that does have the 1.2 bootloader. That's apparently why CWM didn't load.
Where I am now, though, is that I can't get ANY recovery menu to come up. It merely sticks on the main screen with the recovery key detected message, and I have to manually turn it off to reboot. Therefore, loading anything from a zip would be difficult - which I guess might have saved us since I didn't realize VS had slipped in a new bootloader.
But for future use, I might need to get access to that recovery menu ... how do I do that?
.
.
Sounds like stock recovery got flashed over by cwm for 1.1 bootloader. You could try looking over at another site that is something like [email protected] d®∅¡d.com for the new cwm modified for 1.2 bootloader and load it through nvflash. Good luck.
Thanks!

What is TWRP?
I quote
TWRP is an open source, community project. TWRP development is done by roughly 4 people at this point. We also have a large support community with many people who are willing to answer questions and help people with their devices either through our IRC channel or on forums like xda-developers.
Team Win was originally formed to work on porting WiMAX to CM7 for the HTC EVO 4G. After our work on the EVO 4G we wanted to work on a project that would work on more devices than just the EVO 4G and we settled on working on a recovery. Today TWRP is the leading custom recovery for Android phones.
WHAT IS THE USE OF INSTALLING TWRP?
TWRP is used for installing custom software on your device. This custom software can include smaller modifications like rooting your device or even replacing the firmware of the device with a completely custom "ROM" like OmniROM.
You can find the source code for TWRP at github.com/omnirom/android_bootable_recovery/

I just followed your upgrade instructions and was successfully able to upgrade from TWRP 2.7.x and it works great! Results were instant and I was also able to immediately successfully flash a custom ROM to my SM-T230NU. Thanks so much for posting this!

This is where you lost me.
I have Odin v3.12, and it only has one AP button, but no PDA button.
I clicked on AP button in Odin, and selected the twrp image.tar file. Check.
Then you tell me to click on the AP button again and select the CWM file, but if I do that, then the twrp file is no longer selected.
I'm afraid to guess because even though it's old, I don't want to brick this thing.

To get TWRP on my device, I followed the instructions listed here: tab-4/orig-development/twrp-install-twrp-root-samsung-galaxy-t3111934
(I can't post links. Just put forum.xda-developers in front of that)
Instead of using TWRP 3.0.0 or 2.8, I used this newest verison with Odin 3.09 (instead of 3.12)
And it worked on my T230NU
"SOMEONE ANYONE" ...those mysterious instructions entries...
i probably qualify as an anyone, that is im doing this for the first time, though i have some experience with doing the same thing to my old HP Touchpad (tenderloin) device over and over again over the years, to keep it from throwing up alerts about apps stopping... So yes i was confused by the same glitches in the instructions since i dont want to brick my old tablet and try to follow instructions exactly:
A) in STEP 2:
"Device Added on ODIN"
>> no Odin doesnt actually print those words out, i think the op is sort of restating the sentence above it.
B) in STEP 3:
"Click on the AP button (PDA in many Odin versions) and select the CWM recovery file"
>> I think this is just a copy/paste error the op took from some other post and never cleaned up, presumably CWM refers to ClockWorkMod which is different recovery in itself, and i don't suspect you can have two recoveries installed, no? plus, its not mentioned anywhere else in this thread no link of anything, so i just ignored that line and proceeded according to the rest of the instructions.
C) STEP 4:
"Select the ODIN Options"
>> another instance of repeating whats already been instructed in the sentence above it.
So I just ignored the items noted above, the only other thing i did that is different from this thread is i had previously installed the samsung USB drivers noted as seemingly important in other threads, i dont know if that matters since ive never tried it without them, but anyways, I hit 'start' and it worked fine and said PASS in about 5 seconds, then a bit later rebooted, but took a couple minutes to get out of the Samsung logo boot screen -i almost thought it was bricked for a moment there- but it finally came through and it all seems okay. so now i can reboot into TWRP and see all of its options, so now im ready to give a try to install the Pixelized OS!
For my T230NU, TWRP reboots (crashes) reliably in the middle of the wiping-the-cache process:
The TWRPs i tried are "twrp-3.0.0-0-degas.img.tar", "twrp-3.2.1-0-degas.img.tar" , "twrp-3.3.0-0-degas.img.tar"
I selected the usual four items to wipe: "Dalvic cache", "cache", "system", "Data"
(the built-in one-swipe factory-reset wipe crashes just the same)
I installed them all with Odin 3.12.3
This older version seems just fine: "openrecovery-twrp-2.8.0.1-degas.tar"
Will this image work with Verizon Tablet SM-T537V?
Hey, will this work on degaswifi (regular SM-T230)?

Flashed it successfully on my SM-T230NU, however I am also experiencing a crash during a built-in wipe. I reverted back to v3.0.0 and it seems to be working as expected. Thanks,

I have a SM-T230NU (nook). It freezes at boot after the "nook" logo screed is displayed. When I power down it immediately reboots to the same logo screen and again freezes. I can't turn it off without taking the back off and unplugging the battery. When I plug the battery back in after a few minutes, it stays off until I try to boot again and the same cycle repeats itself. Any ideas how to fix this.

[Yes, I'm x-posting. Desperate times, etc.]
I can't get there. Could someone point me towards a solution. Here's the OP link
Thanks
Note 5 doesnt have a bootloader
If you want to root or use any custom roms, you need TWRP,
Steps to root:-
1) Download the latest version of twrp.tar for your device from TWRP's website
2) place it in AP in Odin
3) Shut down your phone then press Volume Down, Home Button, Power button simultaneously to boot to Odin/Download Mode
4) connect to your PC and flash twrp
5) Download Magisk v23 from Magisk's github.
6) use an OTG or place it on your phone's sdcard.
7) TWRP is a recovery, so, to open it, shut down your device and then click Volume Up, Home Button, Power button simultaneously until you see the Samsung Note 5 logo, then release the power button only until you boot to recovery.
8) Install it from TWRP
The reason i said v23 instead of v24 is because Magisk Hide is off as default for v24, so, better to install v23 then update magisk later from its app.

You are kind. Thank you.
Even with the information you shared, it still wasn't a clear road ahead. After numerous attempts it became apparent that the ROM revision on the phone ( *DRH1) will not allow TWRP to be installed. After flashing the closest ROM I found (*DQJ1), things finally proceeded as you outlined. Thanks again. I was really stuck.
Thank you both, as this information will be vital, as I try to continue to use my N920P as a daily device. As I am needing to update to a more secure version of Android.

Beware of format Format Data with yes

Some threads suggest that you should Format Data with yes but I would strongly suggest you check twice what you are doing, think again and be sure everything is as should. I bricked my device twice doing format data from TWRP (maybe I should have done this with fastboot). TWRP said it's done but no softbutton, no option to go back and it stuck on that screen for a longer period of time. Forced reboot and you go into bootloop, looks like device wants to go into recovery but nothing happens. The only way out for me was to go into fastboot/rescue and flashing proper (matching what was already on the device) system/kernel/recovery.
OK I admit that format with yes might be safe and OK and it might be only my problem but be warned about possible outcome of doing so.
You most likely didn't brick your device. Ask yourself these three questions (if yes to all of them, then you have bricked your Huawei Honor Note 10):
Can you enter stock recovery? Press and hold VOLUME DOWN and the POWER buttons.
Can you boot to CFW recovery (TWRP only EMUI8) via VOLUME UP and the POWER buttons.
Can you enter fastboot recovery? Press and hold VOLUME DOWN + POWER buttons while plugging in your Huawei Honor Note 10
I have often succeeded in 3 with my own Huawei Honor Note 10. Try all three of these and see if you have any success.

PLEASE BEFORE YOU decide to try this rom, you MUST read all of post 1 and 2 (about 3 minute read). If you think this is an unreasonable request, then stop reading now and find another recovery. Thank you.

Installation Instructions
Note I do NOT run Windows OS so there are no provided instructions on how to install TWRP using Windows. There's lots of tutorials and videos online on how to install TWRP via Windows. Do your own research. If this is unreasonable to you, don't use this TWRP. Questions regarding how to install TWRP using Windows/odin will go unanswered.
You need to boot the P550 into download mode. Power off. Press home button + power + volume down (farthest away from power button) at the same time. Let go when you see "Warning" text on the screen, then choose volume up to continue. Your screen should now show "Downloading... Do not turn off target"
Linux users can use heimdall to flash this recovery. For example,
Code:
heimdall flash --RECOVERY TWRP_3.5.2_9_SM-P550_20210515_Unofficial.img
After flashing the recovery image, you must boot into recovery immediately (using the hardware key combination) to run TWRP, otherwise the Samsung software will overwrite TWRP and you will have to start over again. I usually am already pressing the recovery hardware key combination while the recovery image is being flashed. The flash process will be very quick (a few seconds at most).
The recovery hardware key combination is home button + power + volume up (volume up is closest to the power button) all pressed at the same time.
Updates
Unless Android 12 or LineageOS 19.0 requires some mandatory changes to TWRP, this will be the only TWRP build I make for the forseeable future. There will be no planned updates to 3.5 unless there's a major bug or security vulnerability. The only time you need to boot into TWRP is to upgrade the custom rom.
I have been using this TWRP now for almost 2 months before sharing it here.
