dastrix11: The TWRP file is Recovery only. This is separate from any ROM or Firmware. When the tablet is off and you push Home+Power+Volume Up, and hold them down, this is what launches TWRP Recovery. You said it it "brought up the screen and I rebooted". You mean you successfully launched TWRP? Your tablet being stuck in a boot loop at the Samsung Logo is separate from this fact.

Are you wanting to just root your device and put custom Recovery on it, or are you wanting to Root it, Install the latest Firmware, Install TWRP and a custom ROM?

If you state your objective specifically, we can help accordingly.

YOU'D ALSO NEED MAGISK MANAGER

Is there any version of TWRP avaiable for T550 with nougat?

I recently got the OTA and I tried yesterday to flash the marshmallow one and got myself a nice bootloop.

Did I do something wrong and it should have worked or its just not the right version the one im using?

tried this one twrp_3.0.2-1_SM-P550_mm_15816 and was scared to try this one (the only one where I can read Nougat) twrp_3.1.1-1_sm-t355_251117

thanks.

wait what? I thought this was the thread for that.

What I mean is I flashed the version from there, but states clearly "Marshmallow only", anyways I tried it and I got a bootloop.

Do you mean it should have worked with nougat anyways or that there is somewhere a link to a version im not using??

thank you!

No, this is the cfautoroot thread.

As linked go to the twrp thread and download the mm 3.1.0-1 twrp for the t550.

Last time I checked it was working fine on nougat.

If Samsung have released another twrp breaking firmware then I'll have to look at fixing it again. :rolleyes:

Post any further comments regarding twrp in that thread please.

Hello.

I have a Samsung SM-T550, with stock rom with Android 7.1.1.

I've been trying to figure out to root and install a custom ROM, so that the device could became more fluid.

Thanks for the TWRP recovery for my sm-t550 tablet. I run the stock 7.1.1 upgrade (XAR version), rooted, and debloated. I would love to have a permissive kernel for it. If you know where or who has one to go with nougat, please let me know. I've also tried the JazzROM 5.0 but it ran very slow after I clean flashed it. Went back to stock. Still hoping for a permissive kernel so I can install ViperAtmos 5.5 w/Beats and AdAway properly.

Stuck in a bootloop

Hi, I was trying this for the first time and I screwed up somewhere. I had my tablet T550 in Odin mode and connected to the computer, then I loaded the sm...autoroot.tar file into the AP slot and told it to go, it went and showed the red android and said it was working, but now it has just been cycling through the boot cycle to the black screen with a white Samsung. It's not responding to the power button to power it off, or to the recovery mode or download mode key combinations.

Any idea as to what I should try? I just wanted to get rid of the bloatware apps....

This thread is quite old now and superseded by the TWRP method.

Hold POWER + HOME + VOL DOWN to boot back into download mode.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] WeyardWanderer:
Hi, thanks for answering. I waited for it to die and then held down Power/Home/Vol down as I plugged it in and got it to go into download mode.

I tried using the Root file on this thread and that's where it went into the boot loop. Should I just start the TWRP directions from the beginning, will that override whatever I did here, or is there a necessary intermediary step? I was confused on the TWRP directions when it says to switch to the vol up button when the screen goes blank, I think I tried that at one point and nothing happened. I've tried several things which is probably why I did this to myself.

Any help you can give is greatly appreciated. Thanks.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:
You didn't need to wait for it to die. You should have just followed the instructions and held down POWER + HOME + VOL DOWN.

Once in download mode just flash TWRP. It's important to manually boot to recovery immediately after flashing.

Which Firmware build is your device running and which twrp version did you install?

Hold POWER + VOL DOWN until the device reboots.

It has Nougat 7.1.1

I installed:

NOUGAT

TWRP 3.1.1-1

Thanks for all thehelp ashyx, l really appreciate it! Twrp is now leading and seems to be working. I have supersu 2.82 on the tablet and tries to install it through twrp.

The good news is that my tablet is booting now and I can use it. The bad news is that I don't think it actually rooted, it doesn't seem any different and I still can't delete stupid preloaded apps like Google hangouts.

I didn't clear the cache/dalvik when I installed it, is that necessary? Or possibly something else I overlooked.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] ashyx:

I started this post in the questions section of forum and was directed here for help.

Hello all I'd like to start out with a big thank you for this forum.

Here's my issue, I accidentally wiped my system from TWRP when I was only supposed to be wiping cache.

I've made many attempts using threads here to reload an OS but with no success.

Samsung Galaxy Tab A SM-T550 WiFi running Marshmallow

I have Odin v3.11.1

It will recognize the tablet if I hold home, volume down, and power. It will not recognize it if I reboot to downloading from TWRP.

I tried the first one several times with ODIN and with OTG USB Install from TWRP

AP_T550XXU1AOF5_CL4815461_QB5392794_REV00_user_low _ship_MULTI_CERT.tar

and this one just the once to be sure.

T550ZCU1BQI1_T550CHN1BQI1_HOME.tar

When I try to install the stock AP file it hangs up like this:

<ID:0/010> Added!!

<OSM> Enter CS for MD5..

<OSM> Check MD5.. Do not unplug the cable..

<OSM> Please wait..

<ID:0/010> SingleDownload.

<ID:0/010> aboot.mbn

I had no back-up files on the tablet and just recently cleared out files on my PC that were my back-ups. Always happens that way, keep something forever and never need it, as soon as you get rid of it it's needed.

When I attempt to install from TWRP I the the error:

Could not find 'meta-inf/com/google/android/update-binary' in the zip file.

Unsure as to what I am not doing right.

Any help greatly appreciated.

I was finally able to boot to stock recovery and found my appropriate MD5 file T550XXU1AOCF_T550XAR1AOCF

and tried to load with ODIN, my results:

It is the P550. If it matters it is the Canadian version. I am downloading the entire 1.5GB firmware from Sammobile to see if I can get it back to original and have a plan if things go bad again.

Update:

Install of full firmware went OK. Was in a boot loop but deleting cache and data solved that.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] retiredtab:
1. What root program were you using?

The P550 is the s-pen version. In order for s-pen to work, it needs to load a specific driver called WACOM and it needs a specific set of kernel parameters, which I have yet to discover, in order for the screen and s-pen to work.

If the root program messed around with one of the kernel parameters or removed the WACOM driver, then the x-axis will be reversed.

2. What LineageOS version did you load? Was it one of my 16.0 or 17.1 roms (see below)?

First, thanks to all you XDA contributors! You've helped me breathe new life (and security updates) into older tablets for various family members. It's great to help them get a little more value out of their purchase.

I'm still very much a beginner and have gotten stuck with this T350. I've tried to stitch together various suggestions and instructions across threads, countering errors along the way - expect I did something incorrectly. Before I grasp at more threads and potentially do more damage, would appreciate informed guidance on next steps.

Thanks!

Here's what I've done:

device was running 7.1.1 Nougat before starting

successfully flashed TWRP (3.1.0-0) to recovery (file: twrp_3.1.0-1_sm-t350_18317.tar) via ODIN (3.14.1). Attempted to initially use TWRP 3.3.1 linked, but ODIN failed. Never experienced the blank screen (backlight) issue others reported. Honestly don't know if that applies to this T350.

successfully installed no-verity-opt-encrypt-6.1 and Magisk-v20.4 via TWRP

in preparation for installing a new ROM (which failed), did a wipe to include the System partition plus the cache options. although i didn't care about the data, i didn't backup any partitions. :(

Here's where I am:

every attempt to power-off results in a reboot. tell TWRP to Power Off...reboot. power button and/or key combos...reboot.

each device restart stops at the Samsung Galaxy Tab A splash screen. Top of the screen states in yellow text "Set warranty bit: kernel".

can still get into recover modes with the different button combos.

can access (ODIN Mode) screen via pwr-down-home buttons. and can connect with the ODIN client. The screen does tell me Current Binary: Custom; System Status: Custom.

can still access TWRP via pwr-up-home buttons.

TWRP and other prompts tell me "No OS installed!"

attempting to install various ROMs is unsuccessful

CRdroid - TWRP gives E3004 error because the device model cannot be detected properly.

Stock ROM (T350XXU1BPI1..) - TWRP gives error "Invalid zip file format".

At this point I don't know if this is a TWRP issue or some other self-imposed issue that is easy (or difficult) to fix. Again, appreciate guidance from those far more experienced on where to spend my time next.
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lpedia:
Holding Volume Down+Power while it's connected to power should turn the device off. Did you try that? Otherwise it simply forces a reboot.

I don't think you can flash the stock ROM with TWRP. Did you try with Odin?
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] wjwjw:
Thanks for catching that. Successfully flashed back to stock with Odin.

It just wouldn't power off even with power supplied. But flashing back to stock ROM eliminated the issue.

----

So I restarted the process...now with Marshmallow 6.0.1

Confirmed via DevCheck my T350 does NOT have BOE panel.

Via Odin, I can only successfully install TWRP 3.1.0-0 (which gives those E3004 errors not detecting device model when trying to install any custom ROM - and fails).

I cannot install the recommended TWRP 3.3.1-0 - Odin fails. A later version of TWRP is presumably needed to install the custom ROMs.

Other thoughts? Is there another approach I should consider? Another TWRP version to try?

Thanks!
[Samsung Galaxy Tab A series ROMs, Kernels, Recover] lpedia:
Have you tried updating to the recommended TWRP 3.3.1-0 with TWRP rather than with Odin? You'll need to unpack recovery.img from the tar file and flash that via TWRP > Install > Install Image.

If you still can't flash CRdroid, try the [UNOFFICIAL][ROM] LineageOS 17.1 for Galaxy Tab A 8.0 [SM-T350] instead.
