[GUIDE] UNBRICK TAB 3 10.1 P52xx (soft-bricken) - Galaxy Tab 3 10.1 Android Development

Greetings Guys, so after I brick my device a lot of times and i notice there is a limited guide for beginners on p52xx series.So I wrote this guide to share my experience with you guys the different types of brick i have encountered. Please correct me if i am wrong on something.
scenarios:
1) you flash something wrong, got into boot loop and you are able to get into recovery or download more. Please proceed to Odin or Recovery tutorial below, Section A Option A
2) Your device went dark after you flash something wrong, cannot boot up or you drain your battery during or right after you mod your device and it wont charge up. Please proceed to Section A Option B
3) You did nothing but drain your battery and it won't charge up after 0% and shutdown. Please proceed to section A option A *THIS IS NOT BRICKED SITUATION*
Section A: How to boot it up....
There is few options you can do,
Option A: If you didn't mess your boot partition up. you can leave it drain for like hours to days *I have tried to leave it for 7 to 9 days... and charge it again, keep charging about 30 minute to an hour when you see charging sign, then proceed to Section B if you brick your device. If you don't, just start it up normally and let it charge up to 100% before you discharge.
>Drain the battery by leaving it uncharged for days
>Charge it on, you will see charging sign
>Leave it charge for hours
>you can boot up into normal or follow the tutorial below for flashing firmwares.
Option B: If you mess with your boot partition and cause it, better follow @r2d23cpo 's suggestion.
So here is some tip.
When the device failed boot.img and goes into black screen it can make you think it is broken. But In fact it is in boot "Limbo". So because there is no feedback on the screen (image) You never know where the TAB 3 is with reference of Power OFF, Charging, Download mode Boot mode or Recovery mode.
You will be save if you can get away of the corrupt boot. Then get into download mode and use Odin or get into recovery and use a good update.zip or backup.
So our BEST tool is the Three button Start Sequence to get away from the Boot bad image. The truth is that our TAB does not requires the Home Button to be Press. SO we only use Power.,Vol- and/or Vol+.
Here is the Basic.
Get a Clock that shows seconds.
Disconnect USB Cable from TAB. Tab should have at least little battery power. Why, to ensure you get in Power Off Mode and not unknown charging mode.
* Pressing Power Button for 6 consecutive seconds should reset and bring TAB 3 to Power Off Mode. Pressing Longer can actually confuse the device, because it may go in to Boot again or just Get another reset and loop back. So the secret is to Hold Comfortable & Firm you Tab in you hand to ensure you PRESS continuously but only the required time.. Then Press Firm ONLY the Power Button lets say 7 Seconds NOT MORE then release. You do not Know but know you should be in POWER OFF.
* Now Lets go to Download Mode. For That we need only POWER + Vol- ( Vol- is the Closest to Power). Remember to Hold firm your TAB and buttons. A bad contact will interrupt the process. DO not Press TO HARD, you could damage your buttons. But Here is a tip. You want to ensure that your TAB know you Press the Vol-. For this reason you are going to press Firm FIRST the [Vol-]. Now Keep pressing [Vol-] and press [POWER]. In 3 seconds you should see The Warning and the Triangle of Download Mode. if you get there the use Odin to revive your TAB. I am Attaching an Odin Boot file.
If it fails try again. Press [Power] for 7 seconds. Release. Wait 3 seconds. Press [Vol-] then [Power] for 2 seconds. Then while keeping [Vol-] down release [Power], no more than 3 seconds later ===> Download Mode. Now use Odin file
The same goes for Recovery. But in recovery is [Vol+]
Press [Power] for 7 second. Release. Wait 3 seconds. Press [Vol+]then [Power] for 2 seconds. Then while keeping [Vol+] down release [Power], no more than 3 seconds later ===> Recovery Mode., now use your backup or the update.zip I gave you.
Now let me explain.
* Press [Power] for 7 second. ==> This in fact after 6 seconds trigger Power Off Mode.
* Release. Wait 3 seconds. ==> This ensure that you guys do not trigger Power On or even a second time Power Off.
* Press [Vol+]then [Power] for 2 seconds. ==> Please note that we first press [Vol] so that there is no doubt that you want to Power on in a special mode. You press [Power] for 2 seconds only so that it Power On and in fact do not reach the 6 second for another power off!
* Then while keeping [Vol+] down release [Power] ==> You need to release [Power] so that you do not trigger another Power Off. But need to HOLD [Vol] for about 3 seconds so that it boots in Download or recovery Mode.
Please Note the dilemma. Keeping [Power] press more than necessary will result in a unknown state, depending only in how many the devices in fact triggered Power off and or power On!! That is why you need to observe the timing.

Option C: Also suggested by r2d23cpo, Charge your battery separately and see if it works. *I never try that before.* You can actually open up your tab 3 10.1, here is a video, https://www.youtube.com/watch?v=80McioNw3Os
Section B: How to restore back to original firmware with kies or odin
But aware that p5220 p5210 or p5200 are having different firmware and you need to download. So do not completely follow the tutorial in the link below, please check your device model and download the right firmware then you can pretty much follow this tutorial by @Zachisimo:http://forum.xda-developers.com/showthread.php?t=2604681

Nice job.
But I have to raise My PERSONAL VIEW. I know many devices when "leave it drain for like hours to days" to see a device recovery itself works. This devices have a FACTORY image that gets to restore them-self when they see corruption. As an example I seen some PALM devices.
But in Samsung devices you only have one and only one boot.img!!! There is no Factory recovery waiting for you. So discharging the device for me IS NOT A VALID OPTION. Believe me. On top our Device may and most likely WILL NOT charge with a corrupted boot.img. So if you leave the device to discharge you will not be able to recharge the battery unless you open the device pull out the battery and charge it alone!!!. So beware. That is my personal opinion. The rest is fine. Good job.

thanks @r2d23cpo. There is many options that they can chose. I am going to flash stock firmware, i have no choice as my battery is 0% now, it do charge but weird that after i tried option b every time it boot up it will boot up into recovery, but i will shut down again as its 0% battery. It last a bit longer now somehow its 1~2%.
After i force shutdown and i finally stop the boot looping and what i am going to do is wait for it to charge till 60% maybe and flash it with stock firmware and charge it up to 100%. I have a feelings that i will spoil the battery like this. So i have planed to get a replacement.
just now i will get into recovery by pressing (vol - and power and home) it get into recovery. But now i can get into download mode. I am not going to risk now as its still low on battery.
I actually support your view as it is a risk, or we shall call it a gambling. So your option may be safer, however i have no choice but to bet it on my option as this is the 3rd time i did that.

Thanks for the mention! But honestly I got out of this tablet because there was really no development and it was just outright slow. But if anyone needs anything I still have it!

[Q] 2.2 on Vibrant gone wrong

I tried to upgrade to the 2.2 operating system using a guide on android forums.
I originally had a rooted 2.1 OS, I don't know if I unplugged it before the process was complete or if I had to return to a stock OS prior to upgrading; however now I cannot get to download mode to use Odin again.
I have read through some threads and I have a different case, I am not stuck at the Vibrant screen, I get past it. Upon boot up I get the Galaxy S screen followed by an Android System Recovery <3e> screen with some other texts. If I hold the power button, I will get the "Power Reset or Unknown Upload Mode" screen. If I continue to hold the power button, the phone will cycle between those three modes, the Galaxy S screen, the Android System Recovery screen, and the unknown upload mode screen.
I have and am still trying different key combinations to get back to recovery mode in attempts to reload the stock OS and then continue with the 2.2 upgrade.
I have made a video that I will post when I get home later today; any help will be appreciated.
Thanks.

What about pull battery plug in usb hold volume keys while placing battery back in DOWNLOAD MODE
Still flashing , thanks to odin & tw

You will be ok. Learn ODIN and you will have your phone back in a hour or so.

I am no expert by any means but perhaps the following might be of help:
try selecting reinstall packages when the stock recovery screen comes up, this may allow you to access CWM Recovery.
also try-- set up odin on Pc and plug in usb cable to Pc ONLY. Then with power off and phone not connected to Pc hold down both volume up and volume down and plug the usb in FROM computer this should take you to Download mode.

Try to reboot your phone with adb.

To get into download mode do this:
remove battery
replace battery
Hold both volume keys.
plug in USB
at no time touch the power button.
Takes me into download mode every time!

I forgot to mention that although in the android system recovery <3e> mode that I get I can scroll up and down using the vol keys but cannot select ANY options using the power key. None of the other keys can be used for selection either.

When I try to ADB I get the following per command.
If I use the "ADB Devices" command I get "list of devices attached" and nothing more.

HELP! bricked my vibrant

i just flashed simply honey 3.8 via odin, i did back to stock before via odin (came from cm7) but after flashed simply honey, my phone stucked at rainbow screen sayin partition partition stupid partition, so i read that to get rid that rainbow i should flash gb bootloader, then i flashed the bootloader via odin, yeah the rainbow has gone but my phone keeps bootloping in vibrant and bullet screen then sayin partition2 bla bla, i can't get to odin with 2 button combo, it's just go to charging wtf, i can't even get to cwm via 3 buttons combo, help me guys, thx in advance

Have you tried
1. Start Odin
2. Plug USB cable into pc
3. Power off the Phone.
3. Pull the Battery.
5. Plug USB cable into Phone.
6. Press and Hold: Volume UP + Volume DOWN + Power, all at the same time.
7. Re-insert the battery.
8. The phone will power now, when the screen starts a cycle of going to a BLACK screen, release ONLY the POWER button.
9. When you see the download icon release the volume buttons,
10. Odin back to stock by putting the PIT file into the appropriate area and the .tar in the PDA area.

Just checking, did you take out your battery, unplugged the usb, put the battery back in, then held vol up, vol down, and power and released all three as soon as you saw the Vibrant logo?

and if that doesnt work try all the steps above but minus one step! hold down both volume buttons except power and see if that works!

It's not bricked, I know you're mad and frustrated, trust me, I've been there a million times!
Lets try taking out the battery and leave it out for 15 minutes. Reboot your computer and unplug every usb.
Then try the above steps again.

tried it, still my phone can't see the download mode screen, i can't bring it to t-mobile since i don't live in states

If you flashed the bootloaders then the mapping is different. Try power button and volume up without the usb plugged and with the battery in. That should get you in download mode.

You are not bricked. I just had the same thing happen flashing the light version with Rom Manager. Since you flashed the Bootloaders, the key combination has changed. Hold down the volume up and power key. Release when you see the vibrant logo-that should take you into red recovery. When there, go to voodoo, choose disable. It will tell you it is 'actually enable' and will be disabled next boot. So reboot and let it do its thing. When I did it the Android in space finally showed up.
EDIT: I'm pretty sure you don't need to go into download mode to reflash with odin, just disable the lagfix. If it doesn't boot into the Android, then volume down+power will take you into download and reflash after the lagfix is finished disabling.
EDIT 2: And with the Gingerbread bootloader, you can't go into download mode if plugged in anymore. It will not go past the charger like on the Froyo Bootloaders.
EDIT 3: Sorry got the key mapping backwards, lol here it is straight from the Bootloaders site.
Gingerbread Bootloaders - No Rainbow - Fully visible Recovery on all ROMs
Benefits - No more rainbows on Gingerbread 2.3 ROMs like Simply Honey GB, LiDroid, Asgard, etc.
Convenient Key Maps for entering Recovery and Download Modes. (I personally like these mappings over the Standard Vibrant Mapping as you can enter download mode directly without needing to turn off phone or remove battery etc...)
For Recovery - Lower Volume Key + Power Button
For Download - Upper Volume Key + Power Button

I'm impressed with your risk taking capabilities man... Dont know how old you are to Android, and I'm not commenting on that, but from what I see, you are just 15 posts old, and you managed to flash Bootloaders to your phone...
Do read the OP for possible solutions before you flash anything... That said, till you have a screen, its not a brick.
Flash the bootloaders, using the new key mapping, and then flash the ROM, you should be good to go !!!

maybe one of you guys can help me here
i have the rainbow screen and i cannot get computer to recognize phone. i have to get into download mode with a dongle and odin still does not recognize my phone. i cannot boot into recover as the screen is completely rainbowed out and I cannot see what I am doing.
Are there any suggestions on what to do from here?
Thank you

[Q] Old school Note wont boot

I have a stock Note that gets stuck in the boot.
I had a charger cable that was not connecting properly and I was having charging issues. When my phone tried to boot it must not have had enough juice. Here's the recent history
within the last 2 weeks a few random reboots. the ones i remember most were when taking a picture after i took the picture the phone would reboot. there may have been 2 instances when it would reboot and then crash and reboot again and crash. i would remove the battery and restart and it would work fine.
yesterday It rebooted and the Samsung image came up and then the ATT logo along with the Att sound but after that nothing would happen. The Att image screen just stayed on and nothing would happen. i removed battery for a few minutes and retried and got same result. I was able to ( volume down + home + power and get the ": warning customer OS warning " but i could not get anything from ( volume up + home + power. )
today when i replace the battery and try to restart I get Nothing on the screen except the vibration that continues about every 2 seconds as long as i have the power button pushed.
I dont mind rooting if I have to but I assume it would need to boot from SD card or from computer. I do have a backup samsung phone if i need to install something to an SD card.
Thanks in Advance.

sounds like your phone was dirty flashed or something in the system was corrupted/faulty... hopefully not hardware. Are you using the wall outlet to charge with an official.. or somewhat similar, cable? If you can get into download mode (Power + Vol down at boot) .. no need to hold home on the the note i717 by the way.. if you can get into DL mode you can flash a custom recovery (Team Win) or whatever and get into a more robust recovery (stock sucks) by holding Vol up + down + Power at boot then releasing after seeing the samsung logo . . you could try going into the stock recovery and or the system and doing hard resets with wiping the data and all that good... fix permissions for sure
If you are able to get into download mode I would recommend trying to flash a recovery, getting in it.. wiping everything like 4 times and also going into settings and using the -rm way . . then if you wanna keep it stock, go to samsung-updates and get the latest and flash it through ODIN. or if you wanna get root and keep custom recovery just download a ZIP from the dev section and flash it from the recovery. All you gotta do there is put the zip file on the SD card and select flash ... make sure to wipe tho, avoiding the install file of course.
The vibrating every 2 sec sounds like youre not letting it charge right tho... pull the battery , wait.. put it back in. . plug it into a WALL . if it vibrates nonstop when you do that, or when the button is pushed... your button is stuck. may not feel like it but internally those things break. might wanna give it a lil love with the duster. these suckers are easy to open . .
if you need a jtag lemme know!
good luck

old school Note wont reboot
Can I flash a recovery if the phone is not rooted and if so can you tell me how.
If i understood your instructions below I am going to goto samsung-ipdates ( .com/device/?id=SG H-I717 ) and download to my sd card and then insert the sd card and (volume down + power ) and that is all ?
thank you for your patience

You don't need root access to flash a custom recovery, only phone in download mode and Odin on a pc.

I have the same exact issue today. I'm thinking my power button got bumped in my pocket weird and caused a catasprophe. I have a new battery and external charger coming in the mail. Hopefully that fixes me up.
My atrix 2 always had that issue.

Can I flash a recovery if the phone is not rooted and if so can you tell me how.
If i understood your instructions below I am going to goto samsung-ipdates ( .com/device/?id=SG H-I717 ) and download to my sd card and then insert the sd card and (volume down + power ) and that is all ?
thank you for your patience

To get a recovery on the phone you have to be able to get to download mode or into the rom. If you are in the rom, use GOO Manager app from the play store and have it install it. If you cant get into the rom and can just get into download mode (vol down + power) then you will have to use ODIN flashing tool. There are other ways but I recommend getting familiar with ODIN.
You can get ODIN flashable recoveries from teamw.in website... thats the Team Win website http://teamw.in. In odin you are gonna wanna load up the file in the PDA section.. make sure not to select anything other than what is already selected by default in odin.. make sure you have proper samsung drivers installed. if you are unsure, install samsung kies from the website (it installs drivers) or find driver package for samsung devices. With proper drivers installed, you should be able to run ODIN, as administrator, and then plug in the phone that is in download mode... and get a device ID to show up in the box. If you see the box with the device, place the phone down in a safe secure spot, make sure the file is in the PDA spot and then flash. Dont touch it until the box either says PASS or the device fully resets and reboots (sometimes the pass never comes or comes super late). The same procedure goes for downloads from Samsung-updates.com ... PDA slot, device in download mode, ODIN with admin privileges , plug it in, see device ID, put phone down, press flash, wait for the thing to give you a PASS. Flashing full roms takes ALOT long than just a recovery so just chill. When it reboots let it settle for 5-10 min, do a few reboots for good measure.
The instructions to flash a rom via the SD card were as follows: if you get into a custom recovery and have a recovery flashable ZIP file on the SD card that is a full rom which is compatible with the device.. then you can select the ZIP file from the SD card and flash it that way. . . ODIN flashable files come in tar.md5 or just tar. . you cant flash ZIP files from Odin.
To smooth over any issues the phone may have, I would flash a FULL, stock, OFFICIAL rom onto the device.. once booted , if you get that far... do factory reset + format SD.

When you're in download mode does your phone turn itself off quickly? Download mode only stays on for about 4 seconds for me. On normal boot I get 2 glimpses of the Samsung, then a vibration and nothing after that. If I plug into the wall I get eternal rhythmic intermittent vibrations.
Sorry for the questions. I only had this phone for 3 days before this happened so I'm a notenoob.

sounds like a stuck power button. May try and see if its stuck by pressing it a bunch to free it or tapping on the back of the phone where the button is

def a stuck power button.. slide your finger really fast back and forth on it to press and depress it quickly while trying to get it to boot . . . stop to see if it worked, if not keep on doing it till you get lucky.
if youre down to take the phone apart, which is very easy ... 7 or 8 small screws and a lil prying and you can get in there and clean the inside but the button and blast the thing with duster. . on the chip the button is really tiny and could use a lil unstickification im sure. . . duster. . and if youre way down flux remover :x

Thanks.
I took it apart yesterday and ran out of time. I have continuity across both pins on the board above the power button so I imagine you're right.
Thanks again.

No matter how many times I clicked and sprayed duster, I wasn't able to resolve the issue. Due to my lame soldering I used an ebay company for repair. If I am allowed to post the link, please let me know. $40 for the service.

[Q] Bricked phone - Boot loop - Recovery & Download mode not working [HELP]

Hello guys,
I've got a big problem with my I9300 and therefore I would like to ask here for any help. (If I'm in the wrong section, please move the thread to a correct one)
I had installed the Resurrection Remix ROM, v5.2.6. from 30.12.2014 and Googy-Max 2 recovery (CWM based) on my phone. I was using it for days and all worked fine.
One day I turned the phone off and I wanted to restart it. But it never restarted again; it ends up in a boot loop. It shows me the white Samsung Boot-Logo for some seconds, then a total black screen and the same thing repeats in a loop.
So I wanted to get into the recovery for wiping etc. but I couldn’t access the recovery. Nothing happens by pressing the relevant buttons. The device is still hanging in the boot loop. So I wanted to flash via Odin, but this isn't possible. I also can't go into the download mode. After pressing the relevant buttons, the green warning screen appears, which asks me if I really want to go to the download mode. But when I press volume up for "continue" or even if I don't press anything, the phone turns off and the boot loop with the white Samsung Logo starts again.
Therefore I ordered a USB JIG for forcing the device to go into download mode. When I plug the USB JIG in, the device actually goes into download mode but this status holds on only for a few seconds. After accessing download mode through the JIG, after a few seconds the phone turns off, restarts, (and because the JIG is still plugged in) the download mode appears again and it ends in a loop.
At first I thought maybe the power button is sticking and therefore the device turns on and off autonomous. But definitively I can negate it, because I opened the phone and removed the power button and nothing changed. Also by pressing the power button on the mainboard I can clearly hear the "click".
So I started a new attempt. Although the time, in which the device stays in download mode before turning off, is very short (only a few seconds), I tried flashing an other recovery, namely TWRP v2.8.3.0. So I prepared ODIN, plugged the JIG into the device, by appearing the download mode I switched cables and an other person clicked start at ODIN and it worked. So now TWRP is installed. Now I also can't get into recovery but after flashing TWRP there exist two little differences. First, after pressing the relevant buttons, TWRP appears for less than 1 second until the phone turns off. Secondly, when I plug the device in for charging, the Samsung charging logo appears for some seconds, then for less than 1 second appears a charging logo from Lollipop and the device ends up in a loop by displaying alternately the two different charging logos. Before flashing TWRP, the device booted in a boot loop (as I wrote above) by plugging it in for charging.
So the main question: how can I get my device work again
I tried telling you all details so that you have a better view of the problem.
Maybe I should flash a fully (stock) rom, but as I told you the download mode appears only for a few seconds. Flashing a recovery was possible, because the recovery file is very small - 7 MB. A full rom is much bigger and I think by flashing a complete rom, the device would turn off while Odin is flashing, therefore I ask first here for any assistance.
Thank you very much in advance!

Check and make sure that your volume buttons and home button are not stuck also. If they are not, I would suggest a visit to a repair shop as your EMMC chip might be weak already.

Your power button is failing, stuck in 'pressed' position. Try pressing repeatedly power button for several seconds, then release it completely. It shall bring it back to life. Visit your local service, or prepare tin, heat gun and soldering pistol. One button cost $0.2, they are selling them on eBay in sets of three (and 10, and 100....).
Happened to me some time ago, and video on youtube helped me to dismantle my phone, pull broken button out of it, and change it for new.
My phone was cycling like yours.

As said your emmc chip maybe failing.
The dead boot thread maybe of interest to you.

Thank you very much for helping! :good:
So the question is, whether it's the power button's or emmc's fault...
I did a little searching and found this video. I've got exactly the same problem like the guy. At 1:06 following the boot loop, at 1:34 following the problem with downlod mode.
Although he thinks it's caused to the sudden death problem, but at least in my case I think it's wrong because months ago I did the eMMC Brickbug Check.
Also I noticed a probably important detail. When I put the battery in the phone, it automatically turns on without pressing the power button like in 1:04-1:09 in the video. Which normal working phone turns itself on by simply putting in the battery...?
So it must get a command for turning on - (possibly through a defect power button?)
@Virnik0, do you remember, if you could hear the micro-switch clicking on your phone before replacing the button on the mainboard?

Your power button is faulty, replace it before you try fixing anything else.

Thank you very, very much for helping! :good: :good: :good:
Truly the power button was fault although you could hear clearly the "click".
I unsoldered and removed the power module and (by startig with JIG and rebooting via ADB) the phone works as it should. :victory:
Now I'm trying to solder a new power button......it's a bit tricky
Again, thank you very much guys!

I had the same problem, pressed the button many times, and it helped. Thank you for your suggestions

Tab S6 stuck in bootloop, can't get to recovery mode

My Tab S6 tried to auto-install an update yesterday (it is rarely connected to Wifi/internet). It then rebooted. Since then, it's been stuck in a boot loop.
It will display the "Samsung Galaxy Tab S6 | Secured By Knox" logo screen for a few seconds, then switch to the blue "Installing System Update" screen (with the android logo). Installing System Update gets to 28% and stops. Then the rotating icon on the android freezes. Then the device reboots and starts all over again.
Edit: the tablet is 100% stock. It's not been rooted or had any custom ROMs loaded.
I have tried getting to recovery mode, by holding power+volup while it boots. This doesn't seem to change the behavior at all. Any advice is much appreciated.

can you shut it down? try volume down and power button ? if it don't shut down, do this soon as it reboots, hold volume up and down and plug in usb cable to desktop/laptop usb port! it will boot into download mode!

I can't actually shut it down. If I start holding power+voldown right after it boots, the tablet does reboot before getting stuck at 28%. But it reboots--it doesn't power off.
I tried download mode and that actually seemed to work! Specifically, I left the tablet overnight in the reboot loop until the battery drained. Just now, I held down volup+voldown and plugged it into my laptop. I got the green "Warning/Custom OS" screen and then pressed volup to continue. The tablet rebooted pretty quickly after that (I'm guessing due to low battery) so I didn't get a good look at the download mode options.
Once I'm in download mode, can I factory reset the tablet? I don't need to preserve any data/apps/settings.

You cannot reset the tablet from Download mode afaik- You need to enter Recovery Mode to do that.
You can however, flash stock from Download mode using Odin (3.13.3 is best). If you're not confident with doing that, your best option is Factory Reset in Recovery Mode. Hold Volume Up and Power when the Tablet is booting, let go when you see the Samsung logo. The timing can be tricky, but you should be able to do it. Also, you can force a reboot with Volume Down and Power.
Alternatively, if factory reset doesn't work, since you're completely stock, you will still be covered under warrenty.

Thanks for the suggestion. I have tried this many many times. I've tried letting go of the buttons at different times. I've tried holding volup while letting go of power. I've tried this a ton of different ways, and no matter what, the tablet always shows the "Installing system update" screen. Some googling has led me to believe that sometimes, when performing a factory reset, the "Installing system update" screen shows up right before the normal recovery screen. Is it possible that the tablet is trying to get to recovery mode, but can't get past this first step?

Honestly, I don't know - I'm not an expert but I guess it's possible that the update failed and corrupted both System and Recovery.
You'll be covered under warrenty, so maybe just return the Tablet from where you purchased or direct to Samsung, could take a while given the current situation though I guess. If you have a PC, then I think the best option would be to just flash stock yourself, since that's probably all Samsung will do. Even if that doesn't work you'd still be covered under warrenty, as far as I'm aware attempting to flash stock doesn't trip Knox.

Here is solution to unbrick your device!!!

Despair not...I have just come from resolving this exact situation not 30 minutes ago. I'd been trying to flash (using Odin as I decided to stay on Stock and not root this device, for a change) the latest OneUI2.1 releases for my device (SM-T865 - LTE version) and boom in the middle of the Odin update, the flash just failed...I then couldn't reboot and get into neither Recovery, nor Download Mode because it appears my bootloader and recovery both got corrupted.
Here's what you need....
1. Odin app for PC (am on Windows)
2. Your device's Stock firmware (sammobile firmware archive)
3. You will need someone to help you boot the device directly into Download mode (and this is the tricky part because for most of us we are used to get into Bootloader by using the key combination (from Powered Off device) Vol+ and Power On at the same time to get into stock recovery and then scrolling down to option 2 in this menu, "Reboot to Bootloader". Well now you are going to boot directly into Bootloader mode. Here's how you do it...
4. Get your friend to line up the USB-C cable into the port of the device, but DO NOT press it in...yet
5. Press Power off and Vol- buttons at the same time to turn off the device
6. And now you have to to be super fast: if device starts to turn on on its own, YOU press and hold Vol+ and Vol- both at the same time while YOUR FRIEND pushes the USB cable fully into the port - you should now have booted directly into Download mode. (if not repeat this, and remember to be super fast and sync with your friend pushing in the USB cable)...
7. When you get into Download mode, then you are home and dry...
8. Select ONLY the Bootloader file (BL...XX...) in Odin, make sure only "reset time" and "reboot" are ticked, and flash
9. When device reboots, press Vol+ and Power combo to get back into Bootloader mode again...but I think device will reboot into Download mode on its own
10. Now select all the files from your Stock file into the various tabs (BL, CP, CSC, AP...) do not select HOME_CSC as we want to flush this device clean...
11. Flash, and voila...success - you will have lost all your data but rather that than losing the device...
12. Feedback here and let us know if this works? For reference for others in the future...

FYI, I got in this situation, and the previous post did work for me, just takes good timing! Thanks!!!!

Same issue today for me. My tablet showed different screen with green and red text, it allowed me to delete app data, then booted into safe mode, then i had to do factory reset and now i am screwed, as it is refusing to restore any apps and their settings. I will try to flash it back to Android 9, maybe then it will do the restore. I forgot to do any manual backup to SD or so.
Edit: the device upgraded to 10, but reset itself after about 10 minutes of use.
Edit2: i found what caused it. It is caused by Nova Launcher, if i try to set wallpaper.

Just found a news article that there is a RGB/sRGB problem with wallpapers. It might be the problem i had.
I am adding a screenshot of the result.

Yeah, I had that kind of reboot loop from a wallpaper that I downloaded

I can get into download mode. But it kicks me out within a few seconds. Any help please

I have the same problem with a Tab S6 Lite, it is in bootloop and does not let me enter the recovery mode, I can go into download mode and I flashed the latest original firmware Android11, Android10 etc., . I tried them all but always goes in bootloop, and also the bootloop occurs only if I connect the usb cable to the PC, without any sign of life. Do I still have hopes or have I compromised the motherboard?
The reason for all this is because I had followed a guide to give root permissions with magisk, I did everything right, only that the guide was with Android10, while I had Android11 and I was deceived by the fact that in the title of the guide there was written "guide 2021"
, so I did not check the compatibility of operating systems, I was a fool, I know, I hope so much that I did nothing irretrievable, it's my son's tablet!

Did you use HOME CSC or the non HOME CSC when flashing?

Try to install a castom rooted rom which has pre installed also Twrp.

Download the android 11 last rooted rom from there. You install it with odin as as a normal original rom.
Disable in odin auto reboot. After rom install, restart manually and press the correct buttons immediately to boot in Twrp and not to system. Format (not wipe) data from there and reboot to system. If you are lucky it will work..
(I hope you unlocked bootloader before try to root. If you haven't unlocked bootloader this won't work also).

Here is solution to unbrick your device!!!
Despair not...I have just come from resolving this exact situation not 30 minutes ago. I'd been trying to flash (using Odin as I decided to stay on Stock and not root this device, for a change) the latest OneUI2.1 releases for my device (SM-T865 - LTE version) and boom in the middle of the Odin update, the flash just failed...I then couldn't reboot and get into neither Recovery, nor Download Mode because it appears my bootloader and recovery both got corrupted.
Here's what you need....
1. Odin app for PC (am on Windows)
2. Your device's Stock firmware (sammobile firmware archive)
3. You will need someone to help you boot the device directly into Download mode (and this is the tricky part because for most of us we are used to get into Bootloader by using the key combination (from Powered Off device) Vol+ and Power On at the same time to get into stock recovery and then scrolling down to option 2 in this menu, "Reboot to Bootloader". Well now you are going to boot directly into Bootloader mode. Here's how you do it...
4. Get your friend to line up the USB-C cable into the port of the device, but DO NOT press it in...yet
5. Press Power off and Vol- buttons at the same time to turn off the device
6. And now you have to to be super fast: if device starts to turn on on its own, YOU press and hold Vol+ and Vol- both at the same time while YOUR FRIEND pushes the USB cable fully into the port - you should now have booted directly into Download mode. (if not repeat this, and remember to be super fast and sync with your friend pushing in the USB cable)...
7. When you get into Download mode, then you are home and dry...
8. Select ONLY the Bootloader file (BL...XX...) in Odin, make sure only "reset time" and "reboot" are ticked, and flash
9. When device reboots, press Vol+ and Power combo to get back into Bootloader mode again...but I think device will reboot into Download mode on its own
10. Now select all the files from your Stock file into the various tabs (BL, CP, CSC, AP...) do not select HOME_CSC as we want to flush this device clean...
11. Flash, and voila...success - you will have lost all your data but rather that than losing the device...
12. Feedback here and let us know if this works? For reference for others in the future...

Why flashing only the bootloader first? At the moment I'm trying to recover my s20 fe from a bootloop without losing my data

Any tips in recovering my stock s20 fe from a bootloop without losing data? already tried Odin but without success the first try

Same issue today for me. My tablet showed different screen with green and red text, it allowed me to delete app data, then booted into safe mode, then i had to do factory reset and now i am screwed, as it is refusing to restore any apps and their settings. I will try to flash it back to Android 9, maybe then it will do the restore. I forgot to do any manual backup to SD or so.
Edit: the device upgraded to 10, but reset itself after about 10 minutes of use.
Edit2: i found what caused it. It is caused by Nova Launcher, if i try to set wallpaper.

Wiping cache partition in Recovery and reflashing the firmware are basically your only 2 options

Flash in odin the same rom you had. There are 2 csc files in rom, which you use 1 in odin one. Try use the "home csc". Home csc keep KEEPS your data. If you're lucky it may work. (It would work in keeping your data 100% if your rom was ok. Because it isn't you have some changes to work.).
You must try with same rom or newer.
CSC – If you flash the CSC file, it’ll perform a factory reset of your Galaxy device and wipe all data while installing a new firmware to bring your device to the same state as it was when you purchased it. Go with CSC if you want a clean installation.
HOME_CSC – On the other hand, if you want to keep your Samsung phone’s data and settings even flashing the stock firmware, you can select the HOME_CSC file.
