internal format problems-SOLVED

So i formatted my internal storage before a fresh install, which has sent my phone into a bootloop. I've pulled my battery and manually tried to boot into twrp and the blue "TWRP" screen comes up for about 3 seconds and then i'm back to bootlooping. I have the mjb bootloader or I would odin back to stock. download mode does work, and i tried to reflash my recovery which did pass via odin, but I get the same results. Any help would be great

First don't double post. Second press volume button up, home button then power. When phone vibrate let power button go and keep holding other two anthill phone get to recovery mode.
Type from KitKat bar.

First, the double post was an accident, And I and everyone else knows this. Entering recovery is not my issue. But thank you.:good:

Galaxy Tab S SM-800 stuck with flashing TWRP logo

I was provided this device to try and help resolve the issue. I am not sure how it got to this point. I believe that it was rooted with a custom ROM, then the individual tried to install a stock ROM (method unknown).
The current situation is:
Galaxy Tab S 10.5 SM-T800 stuck in a bootloop with the TWRP logo on the screen. I can not get the tablet to go into download mode. I have tried all of the different methods to enter download mode, i.e. Power & Vol - & Home, Drain the battery > Plug into PC while holding Vol - & Home, Power & Vol + & Vol -. None of these combinations do anything. The only thing I can do to get a response is to press Power & Vol +, which reboots the device right back into the TWRP loop after the Samsung Logo. Power button alone does nothing.
The device is seen by Windows with the Samsung Drivers but is not mounted to a drive letter, and I can not mount it.
ADB , fastboot and Odin do not see the device.
I would like to flash a new rom either custom or stock, but I need to be able to get the device into download mode so it can be seen by odin.
Any help would be great.

Probably just timing and pilot error this one. I've never known of any Samsung device boot but be incapable of booting to download mode as download mode is bootloader related.
No working bootloader means dead device.
No matter what state the device is in at the moment with the usb cable removed, hold POWER + VOL DOWN (not up) + HOME until the Samsung boot logo comes up, hold for another couple of seconds then release. Download mode should appear.

I know it should be easy....
I know it should work but it is not, I will make a vid of the process and post. I can not make heads or tails.

Is the home button actually working, are you pressing it firm enough?
If the home button doesn't register then the tablet will simply reboot.
Its a bit odd why twrp doesn't fully boot though unless it's the wrong one.
Does it hang at the twrp logo or continually reboot?

Samsung Galaxy Tab 3 7 Kids T2105 T-2105 can't access recovery mode

I have three (3) Samsung Galaxy Tab Kids T2105 tablets. All are running the latest firmware, T2105UEAOE1.
None of them will boot into recovery. The tabs work, they will boot normally, and then will boot into Download mode. But they will not boot into recovery.
* If I hold down Power+VolUp+Home, or Power+VolUp, continuously, the Tab turns on, and then, about 5 seconds later, turns back off.
* If I hold down Power+VolUp+Home, or Power+VolUp, and release them when the Samsung Logo appears, the device boots normally.
* If I hold down Power+VolUp+Home, or Power+VolUp, and release Power when the Samsung Logo appears, and then continue to hold VolUp and/or Home, the device sits on the Samsung Logo for 20 seconds, then the screen goes blank for a second, then the logo comes back on and sits for 20 seconds, then the screen goes blank... and this cycle repeats until I release the buttons, at which point the device boots normally.
I have done factory resets (through the normal mode settings menus). I have reflashed the latest firmware with Odin3. Nothing seems to fix this problem.
I've been searching the net for hours for this. I see a number of other people who have reported this problem. But nobody has offered a solution. One person stated that he uses "adb reboot recovery" - which is a fine, if ugly, hack - but the fact remains that, for many people, apparently, Stock Android Recovery is not accessible from the Samsung Galaxy Tab Kids T2105.
Does anyone know of an actual solution for this, to restore recovery functionality to this tablet?

Hello,
I have the same tablet, same problem (no stock recovery). None of the button combinations work, and the logo just keeps repeating. My situations is that my 9 yr old daughter locked herself out and can't remember her lock screen password. It's a totally stock tablet (never been rooted or flashed). Because I can't get into the tablet, I'm not sure what firmware version it has, and it does not have USB debugging enabled.
I tried booting into the stock recovery to do a factory reset (since we can't do it in the Settings). I tried flashing the same firmware you mentioned using Odin. It goes through the motions successfully and reboots. But it boots back to the lock screen and its still "locked" (we still see her personal wall paper) - which tells me the flash is not taking. Even though my Odin set up is fine, it does not work (even though everything passed with green lights). I tried going into Safe Mode to try bypassing the lock screen, but even in Safe Mode it still asks for the password. My thinking was to go into Settings and initiate a new password or do a factory reset.
(BTW - the Safe Mode button combination was different for me. Holding Power + Volume Up did not work. Instead I had to hold Power + Volume Up & Down until the logo showed up. Once the logo disapeared, then I had to let go of the Power button only - but continue holding the Volume Up & Down until it fully booted into Safe Mode).
I tried ADB in order to use a password reset/erase command line. But because the USB debugging is not enabled, ADB doesn't see the tablet. There is no other way to enable it via Odin or ADB. And I can't even sideload any Lock Screen Hack apps becuase the table is not rooted, or not USB debugging enabled, or can't get into recovery to flash an .apk or image.
So I am stuck. Why would Samsung block recovery mode??? I have been trying for more than 8 hours. If anyone can help, me and my 9 yr old daughter will greatly appreciate it. My last attempt will be to try Google Device Manager and see if it can somehow unlocks it. Or try Kies (although everything I have read so far says that these have not worked either).
HELPPPPPPPPPP!!!!!!!

Hello,
I'm not sure which one of these did the trick for me, but I was able to get into recovery mode. I'm not sure if your three tables are rooted or not, but I don't think it matters. Try these two methods:
Method #1:
Technically, I think I just stumbled on to this one after successfully completing Method #2 (below). But it's worth trying it first before moving on to Method #2.
-Hold the Home + Volume Up + Power buttons together at the same time (just like the normal process).
-Now, you will probably need to try this next step a couple of time before you get it right. This is because it happens pretty fast and you need to time it perfectly.
-Notice that when the screen turns on, the actual first thing that happens is that the the screen backlight turns on and glows first. This happens first and a split second later the first Samsung logo flashes.
-You need to let go of all three buttons at the same time as soon as you see the backlight turn on, but before the Samsung logo flashes.
This is the sweet spot, and it happens pretty fast. But once you do it at the right time, the tablet will go black again and then the recovey mode will show up. It works for me every time.
Method #2:
I thought somehow the recovey mode portion of the firmware had become corrupter somehow. So I decided to flash a custom recovery using Odin (since at that time I hadn't stumbled onto Method #1 yet). Make sure to use gr8nole's custom recovery version for the SM-T210 and SM-T210R (these are the equivalent wifi versions of our Kids tablet). His versions have fixed some known bugs that CWM/TWRP have with the wifi version of our tablets. Make sure to download and flash the CWM or TWRP .tar file for Odin (I personally have always liked CWM over TWRP).
Here is his link: http://gr8nole.blogspot.com/
Also mentioned here: http://forum.xda-developers.com/showthread.php?t=2437219
-Make sure you have all the correct USB drivers for the tablet installed on your computer.
-Open Odin and load the .tar file that you downloaded from gr8nole into the PDA or AP slot (depending on your Odin version).
-Let Odin check the m5d verification for successful authorization.
-Once Odin is ready, then boot the tablet into Download Mode (Home + Volume Down + Power button)
-Connect the table to a USB cable that is attached to your computer's main USB port.
-Odin should now recognize that the table it connected to a valid COM port.
-Click <Start> button on Odin and it should flash the costum recovey .tar file pretty quickly.
-The tablet will simultaneously flash a progress bar and start to automatically reboot (also pretty quickly).
-Disconnect the tablet from the USB cable now.
If the tablet does not automatically reboot to the new custom recovery screen, then just power off the tablet completely. Wait 30 seconds, and then boot the table to recovery mode use the Method #1 shown above. You should now be able to go into the new custom recovery mode you flashed with Odin (CMW or TWRP). It should all work now.
From this point you can download and install SuperSU to add root (if you want to).
Let me know if this works for you.

How to reliably start TWRP

I have TWRP installed, and have managed to run it a few times. Now I cannot start TWRP at all.
From off, if I switch on, the following happens:
1) Screen with Samsung Galaxy A70 - Secured by Knox
2) 0.5 seconds later another screen, "this phone's bootloader is unlocked and it software integrity. .." and "press power key to continue..."
3) 5 seconds later, same screen as (1)
4) 3 seconds later, red letters "this phone is not running Samsung's official software"
5) 3 seconds later blank screen with "samsung" and then booting to android.

In my experience I have to flash twrp every time I want to use it( I don't know the reason but I couldn't fix it ) , for booting twrp on the other hand I turn off the phone first, then I press power button+volume down until the "this phones bootloader..." screen appears, here is the tricky part, you have to quickly let go of these two buttons, press power button, let go of the power button (after the warning disappeared) and then press volume down button (and hold it) until twrp logo appears, this happens really fast so you may need to do it a few times to get used to it.

Yes, same here, the only time I have managed to run TWRP on this phone, is right after a flash.

Power off the device, plug into a pc, wait for it to start charge, hold vol up and power till it turns on. Wala boots to twrp. If you have magisk installed,you can use the reboot option within magisk.

Samsung changed how to enter recovery on Android 11. Power off device, plug into pc, wait for it to charge, then hold vol up and power till it turns on. Alternatively, if you have magisk installed, use the reboot options within magisk.

I did that. Thanks!
But it has gone to:
Android Recovery
Samsung /a70qxx/a70q
11/RP1A.200720.012./A705FNXXUB5DVB3
user/release-keys
Use volume up/down and power.
Reboot system now
Reboot to bootloader
Apply update from ADB
Apply update from SD card
Wipe date/factory reset
...
...
...
Where is TWRP? It seems it's gone.

That's because you're not installing it properly go back to my guide and follow it exactly and stop listening to these other people. I've been modding this device since it first came out with Android 9, I know every inch of this device. You're getting confused by what other people are telling you

It fails here, on this step. After successful flash of recovery.tar, power + vol down to reboot, cable still connected, nothing you can do now can bring TWRP up. The phone boots into Android.
EDIT: I think I have now got it. I will update in a few mins.

After successful flash of recovery.tar, power and vol down to reboot, as soon as the phone screen goes blank, immediately release all keys and press and hold vol up. Must be as soon as screen goes blank. The device will then reboot twice and land you in twrp splash screen. You must hit vol down and power after successful flash then when screen blanks, vol up. If you miss this step, twrp will not hold and revert back to stock recovery.

Here is the notes I made today:
****************************************************************
INSTALL + START TWRP
phone is off
press up + dn
insert cable
go into download (press up)
ODIN 3.14 + AP:tar(vbmeta.img+twrp.img), auto reboot off, press upload
when it succeeds, press dn + pwr until it reboots
then quickly up + pwr until it starts (no need to hold down)
this starts in TWRP
from powered off
press pwr button
goes into twrp or android(system) -- depending on what was used last time
if we used reboot->system last time it will now **Always** go into system!
to go back into twrp:
switch off
power cable until charge
pwr + up until it starts
****************************************************************
The above means that you CANNOT go back to TWRP unless you have a cable and a PC near by.

Stuck at bootloader unlocked warning

I have TWRP and LineageOS with Magisk installed on my A50. Normally, when my phone boots, I get the following sequence:
1. Phone vibrates.
2. Samsung Logo appears for a very short time, with bootloader unlocked warning at the bottom.
3. A screen showing a bootloader unlock warning at the top and "PRESS POWER KEY TO CONTINUE" appears.
4. After a while or if you press the power key, an additional unofficial software warning appears in red letters at the bottom.
5. After some time the phone continues to boot normally.
My problem is that after the latest reboot ("reboot into recovery" via power menu), it gets stuck at step 4 and won't continue to boot, neither recovery nor system, even if I wait for tens of minutes.
What I've tried:
-reboot with volume +/-/poweroff
-reboot with volume volume -/poweroff
-all of the following with and without USB connected to PC:
-power/volume +/- at boot, both starting after logo screen as well as starting before logo screen, as well as releasing power at logo screen
-power/volume + at boot, both starting after logo screen as well as starting before logo screen, as well as releasing power at logo screen
-power/volume - at boot, both starting after logo screen as well as starting before logo screen, as well as releasing power at logo screen
-volume + at boot, both starting after logo screen as well as starting before logo screen
-volume - at boot, both starting after logo screen as well as starting before logo screen
-volume +/- at boot, both starting after logo screen as well as starting before logo screen
None of these helped. I just get the normal sequence 1-4 and then stuck every damn time. Can't get into recovery or download mode. Can't even power off, obviously.
Is my phone gone for good?

same **** here. for me i cant charge the battery too. but before that with about the same problems i got it to work again for a few days.
now hangs on step 4

With some help I managed to get into download mode, and from there reflash stock rom with ODIN.
Basically, you need to reboot the phone with power/vol+/vol- and as soon as the screen goes black, you release power but keep pressing the volume buttons, and also immediately connect the USB cable with the PC. Timing is key.

bro, you helped me alot, i'm stucked at this screen maybe 2 hours I didnt know what to do.
Btw, I've it just in 1 time =))

I got a way easier Method which has saved me several times
Is something i came up myself
Il be as precise as i can be so everyone understands!
1.Plug the phone to the wall (Your charger to the outlet)
2. Hold Power And Volume - (Volume down) until the phone shows the second charging animation (Which is the one after the first image of the phone charging [A circle with the lightning icon in the middle], this second screen shows a charging animation and the percentage of the battery) This indicates that the phone is fully Turned Off
3. Unplug your phone and the charger off the wall and bring it to your computer
4. Plug your cable to your Computer then back on your phone Hold Volume + and Volume - (Volume up and Volume Down) and plug your phone to your computer WHILE HOLDING BOTH VOLUME BUTTONS.
This little trick will put your phone in download mode so you can restore your device using Odin OR Flash Twrp with Odin and boot to right into Twrp (There is a way to do it without turning the phone on and having to go back to step 1, Follow this Tutorial to do it
(
)
I Hope this helps you all
And Happy Flashing!
