[Q] Samsung Tab recovery - Galaxy Tab 4 Q&A, Help & Troubleshooting

I have three (3) Samsung Galaxy Tab 4 on my table.
I tried to enter recovery mode for all three that what happened:
The first Tab: Start up Logo says "Samsung Galaxy Tab 7" was working well. I used CWM to enter recovery - it shut down and booted up to the mentioned Logo. Nothing else goes with this one anymore.
The second Tab: Startup Logo "i Robot" can not enter into recovery.
The third Tab: Startup Logo just "android" no problem to enter recovery with power + volume.
Conclusion(?): As I have tried ALL possible combinations with power and volume ( the i.Robot) even has a hard home button) the first and the second Tab can not enter into recovery. Is it possible, that there are Tabs without recovery function?

To enter recovery, you need to hold down power, home, and vol+
If you try that and get the robot logo again, try the other volume button, it sounds like you might be mixing them up

No recovery?

thanks for your reply. But please read the questions carefully before your reply. I am fully aware of how to enter the recovery mode. I have done this with various devices. My question was if someone knows if there are devices/models which do not have recovery mode at all. I have two devices, tried all button combinations even with different sequence. However i can not enter into recovery at all....

Thanks sub77. I can do that with the Tab that starts, but I have one that, after trying to reboot into recovery from the CWM app it just goes to the startup logo and no further. The hard button as mentioned don't work and ADB is useless if the phone does not start....

Custom Recovery Won't Open

Hello,
I'm having a issue with Custom Recovery.
I've tryed to install both (CWM and TWRP).
The thing is when I turn off my device to
turn it on again pressing Vol Up + Power + Home I got a message saying "Recovery Booting". But the recovery doesnt start, instead my phone vibrate and begins to boot normally. It doesnt enter in custom recovery mode.
I was hoping someone could help me on this.
My device:
Stock ROM
Root (Edited to get rid of Custom status)
1337UCUAMDL
Does anyone know how to unistall a custom recovery or have any idea why this is happening?
By the way I followed this steps

Are you letting go of the power button when the device vibrates?
This is how I get in recovery...while phone is on, long press power button for power menu, press restart...than only hold the volume up while it restarts and nothing else, it will than boot into recovery

have you tried re-flashing the recovery?
Have you tried downloading one of the simple reboot tools that let you choose to reboot recovery?
Thanks for the help guys.
So I tried enter in recovery thru CWM option (Restart in Recovery) it worked.
But it doesnt work when I try manually (vol up + home + power). I really dont know why.
I'm afraid flashing a custom rom doing this way, because if something goes wrong I wont be able to acess the costume recovery.
Is there a way to unisitall the custom recovery?

when you see that blue text, and even right before that when your s4 vibrates, are you releasing just the power button? also, have you tried mg2195's suggestion? what recovery are you currently running?
Just flash a different recovery using the one u have.when I first rooted my S4 I used ROM manager ,it had the T-Mobile S4 option so I tapped it and it flashed CWM .after reading about "Loki"I decided to go with the auto Loki .I downloaded the auto Loki and flashed it with the recovery I got from ROM manager.not one problem and I like MDOB MF3 rom

This is actually a common problem for some reason. There's an easy workaround:
Long press the power button and choose "power off". Give your phone a few seconds to turn off completely. Once it's off, press and hold these 3 buttons at the same time: POWER+VOLUME UP+HOME. Look at the top left of the screen - as soon as you see little blue text saying entering recovery, let go of all buttons immediately...but be ready...if your phone vibrates (it might be trying to reboot normally again), press and hold those same buttons again until you see the blue text again...then let go immediately. Now you will see your recovery!
Alternatively, when I'm not on a custom ROM that has the reboot options mod built in, I use this app to get to recovery/bootloader easily:

[Info] Guide to entering safe mode, bootloader, stock recovery

Yes, I know, everyone knows how to enter safe mode, bootloader, and recovery.
I found there are some inconsistencies to entering and using recovery depending on your which software you are running. In addition there are multiple ways of entering stock recovery.
Also I always see people asking this question because somehow the keypress order is not intuitive.
Entering Safe Mode
Tablet booted and running Android
Press/Hold Power button until power menu shows up
Tap/Hold Power off option
Choose OK to reboot in safe mode
Tablet powered down
Press/Hold Power button until Google screen shows up, RELEASE Power button
Press/Hold VolDn until Android has booted up
If successful, you will see Safe mode overlayed on bottom left of screen.
Entering Bootloader (ie fastboot mode)
Tablet booted and running Android
From adb
adb reboot bootloader
can also choose recovery from menu after bootloader comes up
From app
Use Quick Boot from Google Play
Tablet powered down
Power+VolDn while booting to enter bootloader
Release buttons after you see bootloader screen
Entering Stock Recovery
Tablet booted and running Android
From adb
adb reboot recovery
From app
Use Quick Boot from Google Play
Tablet powered down
Power+VolUp while booting to enter recovery
You can release buttons after you see Google on screen
When Stock Recovery starts you will see the Android fallen down screen
To bring up the Recovery menu
Power+VolUp to show recovery menu
Must be this sequence Press/Hold Power, THEN Press/Release VolUp, release Power
Within menu
VolUp to move up
VolDn to move down
Power to select
In addition, I found an inconsistency with JSS15J stock recovery that wasn't in the JWR66N recovery
While at the Android fallen down screen if you mistakenly press
VolUp
instead of
Power+VolUp
you will still get the Recovery menu.
However, VolUp will no longer function. It will instead become a toggle for switching between the Recovery menu and the Android fallen down screen
Android fallen down screen
VolUp to toggle recovery menu
Within menu
VolUp does not work since it toggles recovery menu
VolDn to move down
Power to select

I don't remember if there are two images one with and one without the triangle. I think I've only seen the image with the red exclamation point.
I've never seen anything to indicate the red exclamation mark is something you need to pay attention to.
Now if you apply an update and there is an error, then that is something I would pay attention to.

It doesn't load the stuff you added.
It is similar to safe mode on a PC, used to diagnose whether the issue is in the stock ROM or is in something you introduced by installing some app.
I Have a probleme
since a bought TAB 3 10.1 and it's boot into safe mode i'v restart it and turrn it off the back on but it didn't go what should i do ?

Bootloader
If none of that works, try the command with a dash "adb reboot-bootloader" Depends on your device sometimes, sometimes unplugging your device right after you enter this command will keep it from getting stuck at the boot logo screen. If that doesn't work, hold the power button to power device down and then boot it into recovery instead using the button combo. Then you can wipe cache & start all over again.
I'm not even able to get into Recovery. I can get to the bootloader, then I select "Recovery mode" and it shows the Google logo, but it never goes into recovery. I have let it sit at the Google logo for a couple of hours, and end up just holding down the power button to shut it down.
I have tried Skipsofts toolkit, as well as Wug's, to try to unlock the bootloader. This ends up with the device hanging at the "Unlock bootloader" screen after selecting "Yes". Again, I have left it in this state for well over an hour with no change.
Here's some info on my 2013 Nexus 7:
KitKat 4.4.4
Never rooted
Never unlocked bootloader
HW version rev-e
Bootloader version FLO-04.02
I suspect my Nexus knew I was supposed to go on travel next week and is faking sick.
Any help would be appreciated. Thanks.
Hi guys i have a google nexus 5 and it is locked state. It is getting booted again and again but it jiust reaches google logo and again restarts. Safe boot is also enabled so i cant enter in recovery mode also. Please help me ASAP.

[Q] Phone will not boot, nor enter recovery mode HELP!

Was attempting to switch back to stock messaging app, and was using some old rom (mint jelly) with Titanium backup/rooted. I made the following changes :
unfreeze messaging app
restart bluetooth pairings
uninstall beauty face
uninstall best face
and then restarted my phone, and will not come back on? What the hell?
Will not enter recovery, at all. Just stays frozen on SAMSUNG. Not amused, please help if you can
Are you sure you are pressing the correct buttons? Volume UP + Power, when the device vibrates release the Power button and when 'Recovery Booting...' blue text appears release Volume UP button.
If you still can't enter the recovery mode there is only one option left: flash stock firmware with Odin!

however there doesnt look like much i can do with recovery mode. the only backup is a year old and might as well be reflashing. is there some way to get into safe mode and maybe undo the changes i made in TitBackup?
To start Safe Mode you have to Power on the device with the Volume DOWN button pressed, until it boots up

[Q] Bootloop, cant get into fastboot

Hi
I rooted my nexus 10 some months ago. All worked fine until yesterday. I wanted to go back to original firmware and used the WUGs nexus root toolkit to download 4.4.3 version and flash it. But afterwards the tablet doesnt boot anymore. Google logo appears and then the circle thing never goes away. I searched many threads, and all base on going into fastboot and flash again, but thats the problem. I cant get into fastboot. The usual combination (Power and vol+ and vol-) doesnt work! I tried many other combinations with different timings, longer press only vol+ and power ...., I always get to google logo after it vibrates.
Is there any other way to get into the fastboot mode ?
Can I connect it to the computer and interrupt the boot process when I switch it on via the PC?
thanks in advance
regards
Erich
Try to connect it to PC with original usb cable and run "adb devices".
If you see Nexus device, you can try "adb reboot recovery" and upload a ROM to /sdcard with "adb push" for flash it.
Hi
Thanks for your relpy.
But thats the problem, even if I could upload a file with adb, which is not working, how would I flash it if I cant get into fastboot or recovery mode ???
thanks anyway
regards
Erich
I think what patzzz is saying is that it depends on your bootloop, often is the case that when someone is in a bootloop the kernel does initiate and adb is functional. Not always but at times for sure.
So if so you can attempt
adb reboot recovery
Or
adb reboot bootloader
If the above doesn't work than you will have to continue trying to boot to bootloader manually with key presses (which I believe is power on while holding volume down)
Best of luck!
Hi
Thanks for the tip. Unfortunately it doesnt work. It made a batch file which calls adb devices and adb reboot bootloader in a loop, so it can send it to the device if it is found, but the tablet isnt regonized, tried some reboots and no luck, adb cant find it )))-:
regards
Erich
It seems a brick, but you can try using fastboot command instead of adb:
Code:
fastboot devices
fastboot reboot-bootloader

I suggest you do a factory reset from the stock. You have gone back to stock firmware so you should have stock recovery. I had this happen once and this work for me.
Hi
I will try it with fastboot too, maybe it works....
How can I do a factory reset without recovery mode ?
thanks

1.If your tablet is on, turn it off.
2.Press & hold the Power, Volume Up, and Volume Down buttons at the same time for several seconds. You'll see the word "Start" with an arrow drawn around it.
3.Press the Volume Down button twice to highlight Recovery mode.
4.Press the Power button to start Recovery mode. You'll see an image of an Android robot with a red exclamation point and the words "No command."
5.While holding down the Power button, press the Volume Up button.
6.Use the volume buttons to scroll to "Wipe data/factory reset," then press the Power button to select it.
7.Scroll down to "Yes - erase all user data," then press the Power button to select it.
>>2.Press & hold the Power, Volume Up, and Volume Down buttons at the same time for several seconds. You'll see the word "Start" with an arrow drawn around it.
Thats the problem, it doesnt work! Tried it a dozent times, only Google logo appears.....

Can't get into recovery mode

Here's my problem.
I can't get into recovery by pressing the power up, home, power buttons. It says it's 'entering recovery', but then it gives another 'buzz' (like when the phone starts), and just reboots normally.
I used to be able to get into recovery with ROMManager, by selecting the 'boot into recovery'. Then I just got into my CWM and could do whatever I wanted. Now I can't do that anymore, probably because my device is not rooted atm (got CM12 on it though). I wanted to root it, but I can't get into recovery.
I already tried flashing TWRP with Odin (download mode does work), but that doesn't work either. I obviously searched google and XDA for the problem, and I saw suggestions for other phones, like updating the bootloader. But I can't find any information or files for updating the bootloader.

Reboots trying to go custom recovery are normal sometimes.
Lil guide for enter custom recovery (TWRP):
1. Power off your device completely.
2. Press and hold Volume Up, Home and Power buttons simultaneously.
3. Release only the Power button when the logo of Samsung in white appears (you will see little letters in blue and red on the top left of the screen).
4. You will see the blue logo of TWRP (pic attached) then and you can release all buttons and start to navigate for the custom recovery.

Thanks for the reply, but I don't think you understood my question. I know how to get into recovery when it all works. I've done it many times before. The problem is that it shuts down while booting into recovery, and then just reboots normally.
I only installed TWRP because CWM wouldn't work, but TWRP doesn't either. So I guess it has to do with how the device boots into recovery, regardless of what the recovery is.
Anyone? I kinda want to flash another ROM, but I'm unable to right now.

I don't think that's the problem. I have 0 issues with the power button. Also, when I try to boot into recovery, it actually says it's 'starting recovery'. Then it stops with a buzz and reboots.
