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.

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.

I cant get into the download- or recovery-mode by using these keys... so i am not able to flash a new firmware! can anybody help me please? is there a chance to get into the download mode by using an adb-command?

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.

I usually release the power button on the boot screen first and then the other two buttons

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..

From download mode to dead ?

Hi,
yesterday i got my sgs and first i wanted to update it to JM5.
Because 3 of my friends have the same phone i know what to do.
First i tried to get into download mode but it doesn´t work.
I found here in the forum (thread 749470) "Australia Optus Galaxy S no download mode!" that i´m not the only one with this problem.
Someone told me to use "adb reboot download" to enter download mode - and this worked fine. The working android appeared on the screen.
Odin now found the phone and i tried to flash but it always ended with "file analysis....". So I found help in this forum - restart pc, start odin as admin, use another firmware, try other usb port - nothing happened - last thing: remove the battery for 30sec and try again.
NOW: SGS alway shows the same pic: a phone + ! + PC - but PC can´t find phone, phone can´t be switched off - nothing!
What can I do now except taking the phone back to my dealer?
I appended a pic from my display.
Thanks for your help!

if you can not get into download mode, then there is no way to fix it
you'll have to send it back to the store, to have it repaired

hmm, you can press at least the power button for 7-10 seconds, then the phone reboots, mybe you are able to go into download or recovery mode, with those button combinations.
but isn't that icon his screen shows, meant to connect the phone to pc and start kies so kies can fix it? (at least i read sth like that on forum) but if this all doesn'T work i don't know

You can always switch the phone off, pull the battery out. ( Avoid doing so when flashing though. )

This guide is really not all that useful.
Take out the battery, and reboot by first pressing voldown+home and then power and wait until you see the yellow download screen.

I'd recommend not doing anything with a phone that you can't get into download mode from a cold start with. Too much can go wrong. Leave it on stock.

I remember seeing that screen when I thought I had bricked my phone, I think I managed to pull back by removing the battery and trying again.

that is only because your 3 button combination was working
in his case, his 3 buttons are not working
there is a batch of samsung phones that came from factory with the 3 button combo disabled

Having the same issue. Think the stores will replace it under warranty like this?

Then you hard bricked your device, sorry to tell you that. Take it to a service, and see if they can do anything to it, but you most surely bricked the hell out of your device, up to the point of no return.

If you want to boot into download mode try this:
When you see Samsung logo immediately press volume up + down and while holding connect the phone to PC using Type-C.
A warning screen will appear now press Volume Up button to boot into Download mode.

Download mode not open for me :crying: :crying: :crying:

If you are stuck on Samsung Logo, connect to PC and press Vol Down + Power for 7 seconds. It will go to charge mode. Disconnect from PC and it will power off automatically. After that press Volume Up + Down and connect to PC while holding and you will enter download mode. It will ask for confirmation.

Useful. Works

Thank you for this post. I did this and my phone booted to TWRP. (I was flashing TWRP when I encountered the bootloop)
After booting to TWRP, I did an advanced wipe (I left System unchecked). After the wipe, the phone booted normally.

Bricked Phone

Hello, I have the A705FN/DS and I tried do Custom Recovery and ROOT but i'm suck on this screen ( https://imgur.com/lVOX4rt ), i can't boot in recovery or download mode, i can't use the phone, Someone can help me?! Already tried a lot of things on internet but nothing so far..

Try not to panic, I've seen this several times.
- Plug the charger cable into the phone.
- Press and hold all three buttons (up volume/ down volume / power) at the same time and keep holding them, wait (at least 10 seconds+), phone will reboot (keep holding all three buttons and wait), even if it says 'press power button to continue, wait), hold the buttons and wait. It may reboot again....
- Keep holding the buttons until the screen goes black then release all 3, this should take you to a blue screen, slightly different blue to the normal download screen, with 3 options:
1. Press the up button once and quickly to download a customer OS. <- Select this option.
2. Long press the up button to go in device bootlock mode.
3. Press 3 to restart.
Start ODIN and download/flash stock firmware for your phone.
If you do get to download mode, be sure to uncheck 'reboot automatically' in Odin, just in case you have some failures, you can click on the 'Reboot to download' in Odin without have to fuss about with all the button all the time.
You must reboot to download mode EVERY time a failure happens before trying to flash again, else you'll need to do the 3 finger thing all over again.....
Worked for me! :good:
Might take a few attempts to get to the download mode, but you should be able to recover it, no worries (had this last night).
Update if it works!

i installed trwp successfully. After that i decided to flash havok os. After that phone went into bootloop. It loads only to twrp and stacks on twrp logo screen(with its build number) no reaction on buttons. Any chances to do something with Odin?

First, make sure that you've the latest official firmware is downloaded on your computer. Then, prepare your phone's cable by connecting it's one end to the computer, keep the phone disconnected for now.
Open odin, prepare all the official firmware's files including ap, bl, csc etc. All of them. And make sure that you've selected the CSC file, NOT the HomeCSC..
Now, you should read this paragraph completely before taking action. First take yor phone and put you fingers over the volume buttons (both of them, up and down) and the power button. Wait until screen turns off (as you said, it was stucked on TWRP). Once it turns of and it's black, dont waste so much time and connect the other end of the cable to your phone and wait till a blue screen shows up.
Now, if the screen is showing you options like Download Mode or Bootloader Unlocking, tap to volume up to enter download mode. If it's not showing you options and it is showing a warning screen like the screen mentioned in the first entry up here, it's ok, you're in download mode.
Start the proccess with odin. Then tell me the result. If it stucks at the end of the 'SYSTEM' installing, tell me that before waiting longer than 10 minutes after all the sign of life dissapears in odin. Waiting for your respond ^^

Ok, tbh you're phone is in a nice condition. You can relax if you're not. Several hours? This seems long, if it is not about your network speed, I mean if you're installing the firmware from a website please try to install it via frija instead. You can find it here.: https://forum.xda-developers.com/galaxy-a70/how-to/galaxy-a70-firmware-list-variants-t3957239
And, please be sure that you're installing the right firmware for your model.
The only thing you should do is pressing all the buttons simultaneously and connect the phone to the computer while the phone's screen is off. Then enter the download mode.

Oh yes! Thank you, sir! i got to that blue screen.

Why only flashing ap? Flash all the files. Csc And Home_csc has a difference. if you flash csc, your data will be formatted. If you want to keep your data, flash home_csc. Dont flash only ap. How did you try to enter twrp? did you try to flash ap over a phone with custom recovery? Flash all the files. Hope you backed up your data. Try to flash all files with home csc, not only csc. if doesnt work, flash all the files but with csc this time.
To enter download mode, be sure that your phone's screen is black and connect the phone to pc at the same time you press all the buttons.

Samsung Galaxy A50 Issue after Update

Hey People,

I made a normal Update of my Phone 5 days ago after the Update my Phone went off and now it shows a Blue Screen with the Information that something went wrong while the Update.
I tried to repair it with the Smart Switch Pc Software but it don't worked.
I gave it to the store where i bought it but they want that i pay for the fix. Honestly i didn't tried to root it because i needed it for work.
Had someone that issue and can help me how i can fix that by myself?
Kind Regards
Saint

yes you probably can fix it easy
connect your phone to a pc with the usb cable
hold vol- and power to force the phone to reboot.
when the phone shut down, rapidly hold vol+ and vol- .the phone should enter download mode
use odin software to upload the latest firmware of your phone

download mode

That's because only the first part is needed. Just turn off your phone normally and then turn it on simultaneously pressing Volume Down and Power.

Thanks for your reply. I did as you suggested but that gave me a normal boot. I tried as someone else suggested, pressing power+UP volume and that did finally get me to recovery mode! Played around with that for half hour
