no recovery mode after OTA update - Samsung Galaxy S7 Active Questions & Answers

Received OTA update last week, device seamed to freeze on AT&T globe had to use power button to reboot twice. Now i cant get to recovery ( hold power + volume down + home ) and it just keeps flashing samsung logo. Only mod is dev mod for system panel 2 access.

Vol Down is Odin / download mode. Have you tried Vol Up to access the bootloader to do a hard reset?

I have this same issue.
Volume up will load recovery, which will eventually work, but a factory reset there will not restore the recovery to what it was. Volume down will bring it into Download mode, but there's no way to reset using that. It will only allow an ODIN flash.

Does an Odin flash not help?

Correct. I used the ODIN QB2 image before. I just flashed the latest QB4 image.
Every time I enter Recovery, it's trying to install some system update (looks like an OTA?).
I'm going to try updating to the latest OTA and see if it helps.

Updated from QD4 to QF2 through OTA. Same issue. It's trying to install a System Update when I boot into Recovery, then shows No Command. It eventually loads the recovery.

So what happens now when you try to boot? Stuck on Samsung logo?

Boots fine. This error appears to be from the patched engboot failing dm-verity. It should thus show an error until the check fails (AKa working as intended).
@noob21:
If you wait about a minute and press the home button, your recovery will work and you can ignore the error.

AT&T galaxy s3 softbricked

I was trying to install one of drewgarens touchwiz roms. touchwiz milestone 5 firefly i believe. not the most recent one because i was too lazy . boy was that a mistake. everything was going smoothly until it booted and it got stuck on boot. I thought no big deal just go into recovery and use a backup. until i did so and recovery was gone and there was only download mode. I have spent the whole afternoon trying to fix it and none of it has worked. I tried flashing the stock rom and it as well got stuck on boot. I looked at all the AT&t relevant ones and also the international versions. so all in all is there anyway to fix this and has anyone had the same issue? i was flashing from cyanogenmod 10 m1 to the drewgaren rom btw. I can also go to download mode. I tried to flash stock but it still gets stuck on boot. log. I flashed the ATT boot logo and it did not work. all of which were flashed through odin.
any thanks in advance is greatly appreciated.
I think you can flash back to stock with just download mode + odin

Unplug your device. Hold the power button to turn it off. Hold volume up, home, and power. It should go to recovery. If you do the same thing with volume down instead of up, you can get into download mode.

Follow the instructions and you should be able to flash the recovery and continue on with what you were doing. Remember to wipe really good when going from aosp back to any stock based ROM. They are completely different and will cause boot loops if you don't wipe.

K I made it home lol. I'll attach a Odin flashable cwm, it's an older one but it'll get you a recovery, I hope. I just tried it on my phone with Odin, 3.07 both with usb debugging enabled and disabled on my phone and it worked both times. Crap keep getting errors uploading right to xda servers, I'll drop box it in a minute.
Ok here we go Odin cwm--> https://dl.dropbox.com/u/28590257/Odin recovery/CWM-Recovery-LTE-SGS3-v4.tar.md5
Newest twrp --> https://dl.dropbox.com/u/28590257/Odin recovery/twrp2.3.1install.zip
I'll add the newest twrp for you lol. Flash the cwm with odin, should work and then the twrp is a zip you can flash in cwm.
Hope this helps get you a recovery.
Remember in Odin use only PDA and only have auto reboot checked.

This may sound like a stupid question but what boxes do i tick in odin?
After your hooked up and Odin is open under the options on the left side check only Auto Reboot. On the right under files check PDA and use that button to browse your computer and find the cwm you downloaded from my dropbox. Then just hit start on the bottom of the Odin window and let it finish, your phone should reboot when its done. It will get stuck again like you described in your first post but pull the battery, put it back in and boot into recovery using vol up,home and power buttons. That should (if everything flashed OK) put you into cwm 5.5.0.4. Once there wipe data/factory reset then restore the back up you mentioned in your original post, that should get you running again.

If something has happened to your backup then you could try the stock rooted stuff here , just pick the one for your carrier and follow the instructions. :highfive:

I was able to get it into recovery but i realized i did not have my sd card in so i turned it off and put my sd card in. unfortunately i was not able to get it back into recovery i tried flashing it again with the sd card in and no luck
That's odd. Couple of stupid questions on my part just to make sure, you had the right button combo, and, you released the buttons soon as the splash screen came on? Can you still get into download mode? Oh and did you do the wipes while in recovery?

oh my gosh THANK YOU SOOOMUCH. I was worried i would have to take it to at&t ill be sure to press the thanks button.
I take it you got your phone working lol. Glad I could help a little. Little advice, anytime you switch to a different type of ROM (aosp to stock based or the other way around) make sure you wipe data/factory reset before flashing anything. It will save you problems in the long run.
Oh and could you go back and edit your original post and just add solved in brackets to the title for people in trouble looking for info.

Depending on which stock ROM you flashed with odin you should now have a recovery, if not then something isn't right. The full bone stock ROM should have the factory 3e recovery, and the root injected stock ROM should have some version of CWM recovery. A factory reset will most likely fix your boot loop, if there is no recovery flash the rooted stock ROM that matches your device from this guide.

try wiping... 2 different roms won't pay nice if you don't wipe

I'm actually in the exact same situation. I was simply transferring music to my phone when it went into this boot loop. I've tried using ODIN to flash every possible ROM I've been able to find.
Desperately in need of help.
How exactly do I perform a "wipe"?
1. Can you guys get into Download and or Recovery mode?
2. If recovery is available, did you back up? If so, restore or flash back to original Rom.
3. If you can get into Download mode, flash back to a stock Rom, and start fresh.
Might sound obvious, just trying to help. I've learned that often I thought the phone was "done", but after refusing to give up on it, it came back to life...
Just keep trying , sounds recoverable for both.

You can wipe by getting into recovery. Wipe Data, cache, dalvik cache.
I can only get into download mode and I've tried to flash to stock ROM SEVERAL times now to no avail.
I've noticed that the binary counter isn't going up after each attempt though...

Easiest way to install latest TWRP once rooted

Install latest TWRP once rooted, I have a separate thread about how to root your device.
1. Download latest twrp from here http://techerrata.com/browse/twrp2/d851
2. Download Flashify (for root users) from play store
3. Open flashify select recovery file you downloaded then flash it to your device. Done
(Boot into recovery menu when device is powered off)
1. Hold volume down and power button simultaneously
2. Soon as LG logo appears immediately let go of both volume down and home button
3. Repeat step one right after step 2
You will be asked to factory reset your device SELECT YES BOTH TIMES and you should boot right into recovery menu.
Done
Thanks for the guide bit it does not work.
I did as you have explained, flashed the twrp image but it does not go to recovery mode after pressing volume down plus power butto. It turns on normally..??
How do i know if the twrp is properly installed??

PLEASE MENTION THIS IN YOUR GUIDE THAN ONE HAVE TO PRESS THE SAME BUTTONS AGAIN "IMMEDIETELY" AFTER SEEING LG LOGO.
This only works if you have the play store (and thus GAPPS) installed. I however do not.
You should modify the title to reflect that.

Great work on this TWRP. Works great on LP also after using a bumped boot.img and kk aboot also. Anyway to speed up backup's? Seems like over 10 minutes+ to backup to SD Card.

Ok, tried my first backup restore on TWRP from SD Card and it failed! Hmm. Anybody else have a successful restore? Just got my G3 so this is the first TWRP I've tried. Send you a PM OP.
---------- Post added at 12:48 PM ---------- Previous post was at 12:29 PM ----------
Tried TEAMWin's TWRP and backup restore failed also. Must have been a bad backup. Gonna try backup again with TeamWin's and restore and see what happens.
this link from the stock rom thread points to a version 2.8.6.1 which is newer than everything in the OP link
https://docs.google.com/file/d/0BxgcaWaR5dRTZExOQnZGWV91U3M/edit?pli=1
is this the right one to use?
what are the steps to go back to no twerp and no root and back to oem phone?
on my g2 I would go to factory reset in the setting and it would only boot into recovery mode..
I just searched for TeamWin TWRP and D851. Got a link to here: http://teamw.in/project/twrp2/249/ Seems twrp-2.8.7.0-d851.img is latest.
Update: I was trying to find a safe way to update TWRP and went back to the below site. The instructions now say to update with TWRP Manager. It worked flawlessly.
http://teamw.in/project/twrp2/249/
Install TWRP Manager. Tap on Install TWRP. Select your device from the device list (d851) and then tap on Install Recovery. The file will download and be installed automatically.

[Q] Stuck in download mode / boot-image

Hi guys,
could anyone please help, I've been playing around quite a lot with rooting and flashing, but now I'm stuck with a problem I can't solve...
Device
Galaxy Tab S 8.4 WIFI (SM-T700 klimtwifi)
Starting point
Flashed CM12 , with CF root and TWRP
Everything ok, but had some trouble with wifi and root, so I wanted to flash a new rom.
Problem
Tried flashing another rom (can't remember if it was AROMA or BlissPop...), but the flashing got stuck.
Now I can only access Download-mode, not Recovery and normal boot gets stuck in the white Samsung-logo, I get past first screen and some other Samsung-animation.
What I've tried
Access to Recovery, not working (I have a stock-backup on internal SD)
Flashed stock image via Odin (T700XXU1ANL1_T700AUT1ANL1_HOME.tar.md5). Should be on right now, but no change in working.
Re-flash TWRP via Odin (tar-file)
Have I missed something? Any problem with going back and forth between Android 4 and 5?

To elaborate, pressing vol up + power + home does not have any effect. Pressing vol down + home + power gives downloading mode as normal.

Sounds like one of the partitions is damaged, its strange because when you flash the stock firmware it relays all the partitions, just to verify you downloaded one of the big factory images from sammobile.com that's 1.6gb big, then flashed with Odin the extracted tar file...also you might not have a custom recovery installed if you have so vol up and home n power wouldn't work......
Maybe your way out of this is going the other way, flash a custom recovery through Odin, then get into that and use it to install ironrom which is like stock but cleaner.

Just to elaborate when flashing stock through Odin it wipes your custom recovery and root...hence why you need to use auto root again through Odin.

Okay sounds like you've hit a dead end but don't panic your not the first to hit this point with t700.
Okay here's what I want you to do,
1. Open up device manager and completely remove your adb driver making sure to check the "also delete driver " box if shown
2. Download this http://developer.android.com/sdk/win-usb.html the latest Google adb drivers ..DL this ready actually.
3. Completely disable anti virus..remove if you have to, along with windows defender .
4. Restart
5. Download "i know it seems mad" the austrailian firmware http://www.sammobile.com/firmwares/download/43233/T700XXU1ANL1_T700XSA1AOA1_XSA/ and extract the file inside the archieve
6. Right click Odin and run as administrator to be safe.
7. Go for gold and try this...if it works your laughing and can change the firmware or ROM to any local area.
8. If...this doesn't work...restart one last time n try again, if still no then try using another laptop or PC if you can
Good luck keep me updated...I am trying to find you another solution too, got an idea with something called heimdall but not sure as never used it, supposed to be an alternative to Odin.
Hi All, finally had the time to sit down and test your solutions. As it happens, the first (easiest) thing I tried was the timing in pushing recovery boot, according to great help of Maxal. Worked on first attempt, booted into stock recovery, wiped everything and stock rom booted. I was prepared to do it all, so it was funny that a few well-timed presses of buttons solved it .
Now I'm rooted with TWRP and BlissPop again. Thanks everyone for great suggestions and assistance!
I also solved, it was enough to wait for the battery becomes exhausted, recharge the tablet and once off from entering recovery and do a factory reset.
The system is restarted.

Recovery gone / corrupted.

I am no longer able to boot into my recovery. TWRP nor stock / default. I am on a custom ROM. I am on 7.1.2 root with magisk 12. I have tried all the fastboot commands to live boot into recovery. I have tried TWRP official app. I have tried FlashFire. Everytime I try to boot into my recovery my phone just reboots back into the OS.

So you have tried booting into the bootloader and entered "fastboot boot twrp.img" in adb?
This happens to me all the time. Using the advanced reboot menu on my ROM or "adb reboot recovery" while connected to my PC just results in the phone booting back into the OS. Pretty annoying. It has to have something to do with the Slots.
Anyways, to get around this, disconnect the phone from any power source, turn the phone completely off, wait 5-10 seconds, then press and hold Vol Down + Power to get to the bootloader. Then use the volume keys to select Recovery Mode and press power to boot into recovery. This method works every time for me. If this does not work for you or results in some other screen/error/whatever other than booting into TWRP, then you must live boot (as suggested in the above post) into TWRP and flash TWRP RC2.

This happens to me all the time. Using the advanced reboot menu on my ROM or "adb reboot recovery" while connected to my PC just results in the phone booting back into the OS. Pretty annoying. It has to have something to do with the Slots.

I have done this 100+ times. Booting into recovery using any method does not work. Including live booting.

If you are still able to access the bootloader, I would suggest flashing a factory image (removing -w if you want to keep your data) with the flash-all.bat. It sounds as if your recovery partition has been removed somehow making it unable to be booted into. Perhaps flashing the factory image will fix your partitions and solve the problem. It's worth a shot I guess if you can't access it at all. Good luck to you!

How am I supposed to flash a factory image if I can't flash anything? Plus I am on a Linux computer not windows. Isn't .bat windows? Would I need a .sh type of command?

The factory image flashes in bootloader mode and should correct any issue you have. You have to install the Android SDK platform on your Linux machine. Go to this link https://developer.android.com/studio/index.html#tos-header and scroll down to almost the bottom for just the command line tools and follow the instructions to install. Then go to https://developers.google.com/android/images and download the factory image you want to flash and follow the instructions in that link to flash. I don't have a Linux machine myself, but I believe the process is fairly similar and it should work just fine.

Sweet I'll give it a try when I get home later. We got a nasty storm blowing in so I may not get to it today. Also I'll remember to Thank that post tomorrow lol limited to eight a day. When you have 100+ people helping you out at once it's hard to thank each one.

Don't worry about the Thanks, cause I'm sure others have contributed more. Sorry I'm not more familiar with the Linux instructions!
Ok having the same issue as OP. A and B slots do not allow me to boot into recovery mode. It just immediately restarts as soon as the white Google splash screen appears. I have just done a factory reset with N2G47O. After complete, the stock default recovery works fine. I booted TWRP from fast boot to install the latest, issue came again. Trying to get into recovery mode just causes it to bootloop until you hold the volume down button to get bootloader up to boot to system instead. I am downloading and will flash NOF27D (last 7.1.1) to see if I can reinstall twrp from that. I can confirm that installing twrp when on that image worked. Will report back...

I forgot to ask if you were on the latest May security update. If you were on that version then you need to use the Android Verified Signer.zip from chainfire after you flash twrp. What version are you running?

Here is the link to the verifiedbootsigner.zip from Chainfire: https://forum.xda-developers.com/an...signing-boot-images-android-verified-t3600606
Make sure you give him some Thanks and Donate if possible! He has earned plenty of both from all of us Android users!
Instructions: Anytime you flash anything that affects the boot partition (ie. twrp, rom, kernel, etc), make sure to flash the boot signer zip at the end of the flashing before a reboot.

That's only for May and so on correct? I am on April. Heard nasty things form root uses about root screwing up, bootloader problems, etc. So I stayed away from May and stayed on April.

Correct. Only the may bootloader requires the extra zip file to be flashed. I am still on April but I have heard people not having any problems and some having nothing but problems from May. I think I'm going to give it a try tomorrow and see how it goes.
Edit: Tried the May bootloader and couldn't get it to boot a custom rom or TWRP, so I went back to April after flashing the Android O Beta and playing with it for a couple of hours. I feel that the Beta is still too early for a daily driver, but it was nice to mess around with some of the features we will have once this OS is released.
