Booting to recovery with button combination not working

So, after trying out a few firmwares (JM2, JG8, JM5) and kernels (Samset&OC) I can't no longer boot to recovery with Vol UP + Home + power. I can't really say when this problem first occurred, but maybe with JG8 flash. The strange thing is that I can get to recovery with adb reboot recovery and through android console with reboot recovery (when rooted ofc). Also download mode works great.
Things I have tried:
-flash again to JM2 and JM5 with re-partition checked (512 PIT)
-cleared cache+data through recovery
-factory reset through phone code (this also cleared the internal SD)
-took out the battery multiple times
-booted phone without sim
-flashed phone without sim
-changed CSC with phone code
-restore a nandroid backup of JM2. Recovery worked with this one when I took the backup
-there's no external flash card inserted
Soooo..does anyone have any idea about this kind of problem?

i had a similar problem after trying few ROMs. In my case, when i pres the key combi i get the boot logo and then few seconds later the screen goes black and then i see the boot logo again, and this goes forever. and then i tried pressing the same key combination simultaneously and once i see the boot logo i let go the power button and keep the vol up and home pressed, and then only it went into the recovery mode.
hope it works the same for you
Cheers

Agreed, 99.9% chance you are doing it wrong.

mmthabet: I had the exact same experience. Letting go of the power button when the logo appears lets me enter recovery.

or you may need to take out the battery first for a few seconds... after that, you can reinsert it back and try recovery mode...
at least this work for me...

Thanks for replies but none of the solutions work. The recovery mode button combination DID work for a few weeks, but then just stopped working.
I know that I'm doing it right. I have always pressed vol up and home down until the phone loaded recovery and only briefly pressed power button just at the start. I have also tried to remove battery multiple times and once waited 30 mins before re-inserting it.
Trust me, I'm not doing it wrong :s And recovery is working great through adb reboot recovery and shell.

More so a timing issue. Buttons not pressed at the same time.
I get it all the time for all combo's.
Just keep trying.

You might already have this however just in case you dont, check out Quick Boot.
http://www.appbrain.com/app/com.siriusapplications.quickboot
With this app you can boot into recovery mode. Have to be rooted though.

this wont work, if you bricked the phone in a bad flash situation.
in times when this app works, you can easily do adb reboot recover
so this app still doesn't address the real issue of how to get the 3 buttons press hardware recovery mode

I release the buttons right when the first Samsung texts comes on the screen. It will take it to Recovery mode. I also had a "boot loop" few times, if I keep pressing the buttons all the time.
Have you tried release your fingers right in the first texts? I really don`t know what is exactly the right way to press the buttons, but this always have took it to Recovery.

Looks like my latest full wipe with *2767*3855# cured it. Flashed JM5-->full wipe-->samset1.9b-->samset kernel and now it works. It must've got stuck somehow in my previous JM5 installation.

yes
adb reboot download
but it is dangerous, as you can not recover from a bricked state, if your flash is not compatible or if something went wrong with odin, etc.

I you're bricked and can't get into Download or recovery mode, leave the device to boot, it will just show a black screen for a while then will turn its self off, once this happens you should be able to use the key combo.

Any idea how long you waited? Been waiting 5 minutes, hasn't shut off. Mine's a Bell though so I'm guessing I won't have any luck.

The way i do it (no chance of doing it wrong and timing):
hold down+home and then also press the power button for a little more then 10 seconds (so all 3 buttons for 10 seconds). The phone will reset into download mode, never fails in whatever mode the phone originaly was..

Semi Bricked/Bricked Phone Needs Fixing

Hi Guys -
First time android user and attempted rooting using the odin method. I followed the instruction listed here http://forum.xda-developers.com/showthread.php?t=1311194 to the "T" before starting. I was doing alright until after flashing the recovery-cwm-hercules.tar, then it gets weird. It didn't flash to recovery but just rebooted to the main screen (where I could see the background picture with the locker pattern), then it immediately shuts off and the cycle begins again.
The weird thing is that I can't even access recovery mode (hold vol. up+down+power), because I'll see the Clockworkmod logo then it flickers and reboot itself. This happens every time I attempted recovery mode.
My attempts to fix it:
1. I flashed the recovery, http://forum.xda-developers.com/showthread.php?t=1315390, to see if it makes any difference. The same story happens with loading to main screen w/locker then it reboots itself again and again. Sometimes I'll be lucky to input the pattern but before soon it will reboot itself again. Same thing with recovery mode as described above.
2. Flashing the stock kernel provided by http://forum.xda-developers.com/showthread.php?t=1311229 to see if it does anything. Nope, same story for both recovery mode/home screen.
3. The insecure kernel, http://forum.xda-developers.com/showthread.php?t=1320946. Same story. nope, nope.
4. Tried these in all order and permutation. Nada.
5. Tried it both ways using samsung driver/kies.
6. Tried it both ways with/without SIM card.
7. Battery is fully charged when attempting any flashing.
8. All the above in my second computer to no avail.
I'm sorry if this might come across as long winded but I just want you guys to get the full picture. I would really appreciate it if you guys could offer any solutions or advice on how to correct this problem. Please be gentle with this first time android user haha, thanks in advance man.

Manually boot into recovery (vol up/down keys) and make a backup (be sure to do this). Then try wipe data/factory reset through recovery. Sounds like a ROM issue not a hardware issue

First off, thanks roman for the quick reply. That's the thing I can't get to recovery manually with the button combinations. When I do that it gives me this message:
[Picture]White dropbox/mail box with a yellow arrow pointing to the Android
"Verifying internal mmc block
Checksum confirmation check (0)
No need checksum confirmation already exceuted
#manual mode#"
It would then reboot and goes to the screen with the locker then immediately repeats that cycle. It doesn't have any wipe options/restart now/etc.
No way to power it down except with battery removal. I've attempted what you suggested many times too to no avail.

Ok, so if it actually boots into the ROM but reboots, try rebooting to recovery from adb -- "adb reboot recovery"

think it's a no go . i tried using adb recovery method and the same thing would occur, it would restart and seems to load into recovery mode but then I would only see the logo, then it flickers and restart itself.
then the vicious cycle of loading up to the screen-locker and restarting itself begins. guess this is the smartphone version of being friend-zoned.

Have you tried taking battery out then back in and while holding volume up/down plug it back into computer? That has never failed to get me into d/l mode. Man I hope you get it working.

Yeah I tried that and getting to download mode is not the problem. just that recovery mode doesn't boot properly in that it would restarts itself. and when i boot normally to screen, i would see the locker and background picture then within 3 secs, it would restart itself.
Guess last resort is to go to t-mobile store, play dumb, and get samsung on it. only problem is that i worry about the flash rom counter # since mine is like 10 already (my attempts to address this problem). Let's hope those tmobile reps aren't that tech savvy.
Thanks for all the help fellas, great early posting experiences so far.

I'm sorry I've read your post..and i'm confuse, if you're able to go into download mode, then why could you just start Odin and flash the recovery again. If its unsuccessful then check the MD5 to see if you have a bad download. I think you should download the recoveries files again add give Odin another shot..Good luck..

are you able to go into CW recovery ?
if so, you can mount the USB, download a stock ROM, and then flash it using CWR

I understand that but that's the a big problem. If I could go to CW it would be a different story but I can't go into CW recovery. I would be able to see the logo CWR and the version number then immediately it shuts off again and reboot. Happens every time without fail.

did you let go of holding the vol+ & vol- buttons as soon as you see the blue text in CWR ?
it can easily reboot by accident when holding those buttons and hitting power, but the buttons are so responsive it selected the first option to reboot the phone by accident a couple of times on me

I'm positive that I held it properly and long enough. I never got to the blue text, just the CWR logo showing then turns off (like you shutting off a tv) and reboots itself. Trying to flash it again with Odin didn't work either and I tried the recoveries from different sources as well.
I went to the Tmobile store today and seems like they'll mail me a replacement then I'll return my current one to them. Only thing is stocking/processing fee but it's a small price to pay if it resolves everything.

glad they will give you another one..

Dude if you can get into download mode then it can most likely be fixed by flashing stock through odin. This would save you some $$. Just saying.

Dude, I understand that it should but it's not. I've flashed the stock recovery for more than 10 times and I still can't past the home screen. It would just reboot itself in less than 3 sec. And I'm positive I flashed it properly. Believe me I don't want to spend extra money if I don't have too.

[Q] Note 3 wont reboot successfully after flashing CWM recovery

So i decided to flash CWM recovery on my Note 3 via CWM (I had phillz recovery installed already), now the phone just wont boot up. It keeps saying Recovery Booting above the Note 3 logo for 2 seconds, then the phone restarts again showing the same message. I pulled the battery out and then inserted it back in but it boots the phone automatically with the same recovery booting message and restarts every 2 seconds. I cannot boot into recovery or put the phone in Download mode. Have I finally screwed my phone up? Any help would be very appreciated.

Can you Boot into download mode and Odin to stock?
Sent from my SM-N900T using XDA Premium 4 mobile app

I cannot. I have the battery of the phone out right now. As soon as i put the battery in the phone, it tries to reboot into recovery without me even pressing the power button. Then it again shuts off and tries to restart every 2-3 seconds.

Just some additional info, I flashed CWM recovery through Rom Manager. After flashing it, it asked to reboot the phone. As soon as the phone rebooted, i started having this issue.

I'm in a similar situation. I used to be able to use the phone controls (power-home-Vol Up) to be able to go into recovery mode, but even that has stopped functioning. The only way to get the phone to boot normally after that is to pull battery, put the phone in download mode and then cancel download mode to boot up normally.

re: download mode

I think the only way to get your phone into download mode now would be
to get a USB Jig from eBay or some online store.
They are under $5 bucks shipped.
Once you have that you would simply remove the battery from your
phone and then plug in the Jig before putting the battery back in.
The usb Jig is basically meant to be used for those
phones which will not go into download mode any
other way.
I have a Jig and as soon as it's plugged into the phone when the phone
is powered down it goes into download mode within 2-3 seconds.
Soon as its in download mode you can remove the jig and start a
clean Odin flash of the official stock firmware for your phone.
Good luck!

Thanks for that USB Jig suggestion. I guess that is my last hope.

Per suggestion from Misterjunky, I've now been successful in installing the Stock Tmobile 4.4.2 NB4 formware that I downloaded from sammobile. I used Odin 1.85 to install that on the Note 3. So far, the phone looks functional again.

So pressing power, vol down and menu doesn't get you into download? Have you tried holding them for at least 30 seconds?

I had this happen to me when I messed up flashing twrp. Pull the battery for 30 minutes, then put the battery in while holding power home and vol down.
That's what worked for me.

I encountered the same issue after flashing CWM Touch to my SM-N900T (Note3-Aus) running Infamous Rom on the BioShock kernel. After being stuck in the loop for a fair while I removed the battery, went to grab a cup of tea before completely raging at the phone, went back and put the battery back in. The phone did not boot automatically this time, a good sign I thought to myself. I then went on to hold down VolumeDown + Home + Power to see if I could get into download mode. I successfully booted into download mode and selected the reboot option. My Note3 then went on to boot successfully. Hopefully this helps :fingers-crossed:

I recently had the same issue......heres step by step:
1. with the battery OUT, grab the usb and plug into phone and computer
2 press volume down, power, and home at the same time.you should be in download mode at this point, and just press volume up to get into download mode.
3. open kies. and at this point you'd want to restore back sto stock as follows:
4. go to tools, firmware upgrade and intialisation
5. follow the on screen direction and then just wait.
6. if you want to re root, then feel free to once the phone is up and running.
i have tried this method so many times and hasnt failed me yet. IF this has helped anyone, please press the thank you button! :laugh::fingers-crossed:

I resolved the problem by flashing the phone back to T-mobile stock using Odin. In my case, the recovery was corrupted and hence the issue. After flashing back to stock, I was then able to root and install a TWRP recovery successfully.

I'm having the same problem, what I do is take out the battery put it back in and try to turn on the phone on recovery mode, and it will give me the option to restart the phone. Hope it works

Same problem has happened to me, do you guys know if the jigs are universal? The ones I see on amazon and ebay dont list the note 3 at all so I just want to be safe. Since upgrading to nf9 the recoveries have given me major issues, TWRP was really buggy so I switched back to CWM and this happens.
Scratch that, just rebooted. I would still like to know if its universal though, in case this happens again. Doesnt hurt to be prepared

You're a life saver, Thanks a ton

Then I Flashed CWM ( n900-cwm-recovery-6.0.5.0-kk_L5.0(0812)) and all seemed to go well but .. I could not get into
recovery mode. when I pressed vol up + Home + power key at the same time it went directly to download modes second screen..( the one that is ready for you to hit start on odin.) ...
I was able to reboot and try several times with the same result.
I then went and got the CWM app and tried to enter form there to only get stuck on the download mode without being able to reset.
then I flashed the CWM again and was back to being able to reset but not being able to get into recovery mode.
I updated CWM recovery setup from the app to the latest 6.0.4. and then tried to back up my current rom ... this let to a boot loop that said something like ..... Kernel is not seandroid enforcing...
once again I was able to get into download mode and had to re flash CWM and get back to my original problem ... not being able to get into download mode

[Q] Need Help - SM T705 stuck on start up screen.

Greetings XDA Developers,
Newbie here. I own a Samsung Galaxy Tab S (SM T705). I was able to root it a few weeks ago and I decided to install a custom recovery (TWRP) using an app from the Playstore named "TWRP Manager". I didn't hesitate to do so using this method because I was able to install TWRP on my GT I9300 successfully from the past using this app. However, after being prompted by the app that the recovery was successfully installed and needs to reboot the device, my tab was stuck on start up screen ( See attached photo ). I tried long pressing the power button but nothing happened. I waited until the device ran out of battery and when it did, I plugged in the charger and I'm back at the same screen. After google-ing some possible solutions, I tried to boot it into recovery but was unsuccessful, however, I was able to boot into download mode.
I'd like to ask for the help of some "experienced" users in this forum on how to solve this problem. And if possible, I'm hoping that flashing a stock recovery using Odin wouldn't be my last resort.
Thank you in advance.

Your going to need some fast hands for this one! I've ran into this lots of times when testing kernels and such. Any force reboot by holding Power Button+ Home Button + BOTH Volume buttons all at the same time. Press and hold that combo until the screen goes black. Then once the screen goes black quickly press and hold Power Button+ Home Button + Volume down buttons all at the same time. You should no enter into download mode. You said that you drained the battery so I would suggest charging it in download mode for 30 minutes or so then flash TWRP with Odin.
Your going to need to flash stock recovery or TWRP with Odin to override the boot and get it working
The TWRP app doesn't always work in which is why I use Odin.

As a side note for future reference, hard reset is simply hold POWER + VOL DOWN.
As said all you need do is boot to download mode and flash recovery.
If you're on lollipop you may need to immediately boot into recovery after flashing to make it stick.

Hey, thanks for the heads up. But how exactly do I "immediately boot into recovery after flashing to make it stick." Since after I flash recovery via odin, it would obviously automatically reboot my device? sorry for the dumb question.

You either be quick and hold POWER + HOME + VOL UP as soon as it reboots or you uncheck auto reboot in Odin then restart manually.

OMG Please help! Bootloop, can't get into recovery but able to get into download mode

I have a SM-G925T and it started boot loop today. I tried to get into recovery mode by holding Power+VOL UP+Home but that does nothing. When I tried to go into download mode by holding Power+VOL DOWN+Home, it works fine.
Symptom:
Phone boot loops displaying only the very first Samsung screen with Galaxy s6 edge (no samsung boot animation). Once this very first logo screen comes on, the screen goes black and loops again. Even if I plug the OEM Samsung USB charging cable, screen does not show the battery charging screen, just the same Samsung Galaxy s6 edge screen.
I have already tried the following:
1. Flash stock rom using ODIN, flashed successfully, still boot loop
2. Holding Power+Vol DOWN to reset, still boot loop
3. Flash stock rom using ODIN again, flashed successfully, still boot loop
4. Let battery drain, waited 3 hours for screen to boot loop and battery died, plugged back USB charging cable back, still boot loop
5. Flick the power button many times to loosen any dirt, still boot loop
6. Hold the power button for 1 minute, 2 minute, and 3 minute, still boot loop
Please help, any advice very appreciated!

Hm, I had this 2 month ago with a S4...
Same thing, I go to my provider he checked the Handy and said I have a defect on my Mainboard... He use dos tools for Handy analysis... I flash stock with Odin, too... Success but no boot...

I have a SM-G925T and it started boot loop today. I tried to get into recovery mode by holding Power+VOL UP+Home but that does nothing. When I tried to go into download mode by holding Power+VOL DOWN+Home, it works fine.
Symptom:
Phone boot loops displaying only the very first Samsung screen with Galaxy s6 edge (no samsung boot animation). Once this very first logo screen comes on, the screen goes black and loops again. Even if I plug the OEM Samsung USB charging cable, screen does not show the battery charging screen, just the same Samsung Galaxy s6 edge screen.
I have already tried the following:
1. Flash stock rom using ODIN, flashed successfully, still boot loop
2. Holding Power+Vol DOWN to reset, still boot loop
3. Flash stock rom using ODIN again, flashed successfully, still boot loop
4. Let battery drain, waited 3 hours for screen to boot loop and battery died, plugged back USB charging cable back, still boot loop
5. Flick the power button many times to loosen any dirt, still boot loop
6. Hold the power button for 1 minute, 2 minute, and 3 minute, still boot loop
Please help, any advice very appreciated!

Hold the button combo pwr, vol down and home as if you want to go into download mode, but try to time it that immediately before the download mode screen comes on, use the Vol up, home and pwr combo and keep holding it down, till it goes into recovery. You have to time it so that right begore the download screen lites up you shift to the recovery mode 3 button combo and hold it till it goes into recovery. This works for me and how I do it all the time whether using stock recovery or TWRP.

Thanks for your suggestion Docmjldds but that didn't work either. I think I timed it within 0.5 second of the download mode screen. I always tried cancelling out of download mode and quickly holding the combo vol up, home, and pwr immediately after it and it that did not work either.

What version Odin?
What version stock ROM?
What version Recovery?
Have you tried to simply install latest TWRP 3.1.0 "twrp-3.1.0-0-zeroltetmo.img.tar"

I have the solution for you my friend. Flash TWRP using oding (in download mode), then from TWRP install or flash this rom(for this you need to download the rom, connect your phone to the pc and while you have TWRP open in your screen put the file of the rom in the phone)
Rom right here:
https://forum.xda-developers.com/ga...ied-development/noble-nougat-rom-1-0-t3565293
This works because this rom comes with its own bootloader and kernel.

Really appreciate your help here. Would flashing TWRP with odin trip knox? I'm afraid to flash anything not stock rom related.

Really appreciate your help also.
I'm using Odin v3.11.1
Tried both stock ROM version
- G925TUVS5EQA2_G925TTMB5EQA2_TMB
- G925TUVU5EQC2_G925TTMB5EQC2_TMB
Stock recovery was flashed successfully as part of ROM above
I've not tried installing TWRP, could you please point me to where I can find it and how to install it? Also, would installing it trip up my knox?
I also flashed recovery.img by itself by extracting that from the ROM and converting it to recovery.tar.md5 using tar-Tool and successfully flashed recovery only but still no difference.

Flashing TWRP WILL trip knox. So, if that's a concern to you, then not much more I can tell you about that. BUT.....3.12.3 is latest ODIN. I would use THAT. Then try flashing complete stock firmware from download mode. QC2 being the last. Here is latest ODIN I attached.

PS: Have you tried turning phone off. Then power on and then immediately hold the vol up home pwr buttons combo. That should also get you into recovery mode. But that said, I would still try my last.

He wants to keep stock. NOT a good idea

I used the ODIN 3.12.3 that you posted and flashed QC2 again (Passed/succeeded). Still boot loops.
I can easily get into download mode but not recovery mode. I don't know of a way to power off, just reset by holding power button or (power button and vol down). I just realized how ridiculous this sounds but is there any way to actually power off the phone without loading android and holding power button, and selecting power off? As far as I know, there's only soft reset or hard reset.
I'm pretty sure my hardware buttons work fine since I need to hold power button, vol down, and home at the same time to enter download mode perfectly. Then I have to press volume up button to enter download mode. So all the buttons that's needed to enter recovery mode (power, volume down, and home) works.
Wonder if bad battery can be be the cause? I don't get any charging indicator (screen with battery animation) when I plug phone to USB charger. Seems to be able to hold a charge but not that long, no way for me to check battery percentage though.

It's your only option right now. I was where you were and I have the same phone 925T. I flashed the rom I told you about then I flashed the stock nougat rom that just came out 2 days ago. I'm running the stock nougat and I'm happy at the moment. Battery and performance are great. I tried flashing all of the stock roms using ODIN and nothing would work but flashing that rom I linked you before worked and then I was able to go back to stock. Trip Knox sure but you will have a working phone again.
The reason why I went back to stock is because I need WIFI calling.

Before doing all this, if you don't want to void your warranty.
1-Download the stock NOUGAT, flash it using odin and then if it lets you go in recovery mode, factory reset your phone then try to boot. Give it 5-10 minutes to make sure it doesn't actually boot. I know the first boot takes a while so you will be stuck at the t-mobile logo. If after 10 minutes doesn't go on then try number 2.
2-Having the phone in download mode use the software smart switch.

If none of that works, either use your warranty or

So I just flashed the latest nougat stock firmware with ODIN. Flashed passed/succeeded. No difference, still boot loop Still cannot get into recovery mode but can get into download mode fine like before.
My phone is out of warranty so I'm just gonna buy a replacement battery off ebay and see if that makes any difference. Hope someone has other ideas. I'll use TWRP as a last resort. Maybe that will work but I don't know how not being able to get into stock recovery would be fixed by installing TWRP custom recovery. I suspect I would not be able to get into TWRP recovery either.

Why are you so concerned about tripping knox, since you are out of warranty anyways. And BTW it's a myth that a rooted phone loses warranty. I have had plenty of my phones covered under warranty and they were ALL rooted. With TWRP installed, you can use the advanced wipe actions to basically factory reset and load either Nougat or MM stock. I am rooted using stock just released Android 7 for TMobile firmware. Odin Firmware. Odin TWRP. Then install anything you like. Yes...knox tripped. Yes, you will lose Samsung Pay. For me not a big deal. Otherwise just fine. The warranty comany has to prove that your act of rooting caused the issue the phone has. Samsung will tell people that phone warranty is voind if rooted. But it's ONLY a line they are told to state. Again, I have used Samsung warranty direct...NOT TMobile and obtained free warranty service and my phones were rooted.

The biggest concern about tripping knox for me is that I lose Samsung Pay. It's actually the most useful thing I have on the phone. I can do pretty much every thing on my old phones that I need but it doesn't have samsung pay. I understand it's useless for most people, but for me it's the most important feature.
Do you think i would still have the same problem getting into recovery even if I flashed TWRP? Right now I can't even load stock recovery.

I really have no idea why you are having this issue. The one time my phone was so screwed up was I could ONLY fix by doing a complete factory reset including internal memory and that was via TWRP. Installing TWRP WILL kill Knox, therefore no more Samsung Pay...period. Have you tried smart switch out of curiosity?

I think my problem is worst than what you had before because I cannot even get into recovery mode not just a normal boot loop. This issue is boot loop and not being able to get into recovery mode.
I have not used smart switch yet. I was going to do an emergency software recovery but that would basically just wipe all internal memory and flash the stock rom. I thought I could save some of my data by just flashing stock rom with ODIN, which flashed perfectly every time but still boot loops.

The only thing I can think of is that your setup is so corrupted you basically have no choice here. It's kind of the old adage about knowing it's important to occasionally back up the internal data, but just never get to it. I'm kind of paranoid to every now and then make sure I have copies of stuff around. I know it's zero solace for you, but without getting into recovery mode, there is no way to get to the Internal stuff that I know of. I'm assuming you never used smartswitch to backup or just use a computer to copy paste Internal stuff to a folder for saving.

Try this stock Recovery. I found a post I made almost two years ago with a link to this file. Use the password to open the file and try ODIN again

Really appreciate your help. I'm starting to think more that it's a bad battery now. Hope that's just it instead of the main board.
I left phone on charge for a few hours (constantly boot looping the whole time). I'm able to power off the phone by holding Power button and Volume down for 10 seconds. Screen is completely off, no boot looping.
Step1: When try to simply turn phone on by holding power button for three seconds, the first samsung galaxy s6 edge logo screen pops up but then goes away and phone looks to be off. Like it's trying to get power from the battery but can't.
Step2: If I keep holding the power button, that first logo screen would turn on and off as if it's a boot loop. If I let go, then phone is off again.
Step3: If I go into download mode and select Cancel (restart phone), it goes into boot loop with only first logo screen again. It loops until I hard reset by holding power button and volume down again for 10 seconds. Then phone is off. Same thing repeats if I go back to Step1 again.
