Question [SOLVED] Going into recovery mode issue - Samsung Galaxy A12

Hi. I have a Galaxy A12 that Im trying to get into recovery mode so I can reset it. I cant remember the pattern. I have tried two methods but both have failed, each time, where you would normally see the Android person and it boot into recovery, it just beeps and boots normally.
I have tried putting a pin locked SIM into the phone, powering it off. Holding Vol Up and Power until you see the Samsung logo. Then letting go of Power and holding Vol Up. Doesnt work just get the beep.
I have also held Vol Down, held Power and restarted the phone then switched to the Vol Up key.
Both times I just get a beep and it boots into normal OS.
Anyone come across this and know how to get the A12 into recovery mode so I can factory reset it.
Thanks in advance.

[Q] Phone won't boot into recovery or otherwise

Hi there,
Sorry but I think I finally found the right forum for this and I wanted to take one more stab before kissing this phone goodbye.
I have a Rogers Galaxy SGH-i727R. About three weeks ago, the phone started re-starting on it's own. I though maybe it was a sticky power key and had that replaced. The problem persisted. I then noticed that it was primarily upon receiving text messages that the phone would reboot. So it seemed it was a software issue. I am running the stable build of CM9.
Yesterday the phone rebooted and never got off the angry alien screen. I pulled the battery, charged it etc and still could not get it to fully boot up. I left it for over an hour. I finally decided to call it quits and re-flash the phone. Problem is, it will not boot into recovery at all. When I hold down Vol + - and Power, it jsut goes into a loop of vibrating every three seconds until I let go and then it tries a normal boot again. Once, I briefly got a screen saying I was trying to install custom software and to press volume up to do so, but before I could hit volume up, the phone cycled off.
I should also mention that the four buttons on the bottom of the screen do not work. I accidentally sliced the wires on the side of the phone when opening it up. I use a software button saver widget to access their functions. I wonder if that issue is related....
Thanks for any advice. I would like to get into recovery so I can load a new ROM or a stock ROM.
If you haven't ventured there yet in this forum I'd recommend Vincom's roundup on just about everything http://forum.xda-developers.com/showthread.php?t=1652398. I don't know if it will help much in your situation but it's worth a look. Also, you may want to research usb jigs, not sure if they will work with our devices though ... research is the key word.

All I can tell you is that your problem sounds exactly like a stuck power button. I know you replaced it but all the symptoms you point out suggest stuck power button. Maybe try cleaning it again?

But if it were a stuck power button it would not stay on the loading screen indefinitely, no? If I hold down the power button while booting, it will turn the phone off.
Hold vol +- and pwr until it vibrates let go of pwr continue to hold vol +-. You were letting go of all of them at once going by your described method.

[Q] All my buttons just stopped working!

Haven't changed anything on the phone at all today, no new apps or new settings.. About half an hour ago all my buttons stopped responding. Power button, volume rocker don't do anything. Strangely enough, holding the power button still restarts the phone, and holding the volume down button at the same time still gets me into fastboot.. so clearly it's not a hardware issue.
Also, plugging the phone in doesn't register that it's charging.. however if I restart the phone while it's plugged in it will register that it's charging, but unplugging it will still show that it's charging. I've obviously restarted the phone several times already.. any clue what this bizarre issue could be?

S7 maybe fullbricked

Hi,
i update my Galaxy S7 today with the new DBT-Firmware. I follow a Tutorial in which you can update a rooted Phone with flashify it without loss any data. Also the TWRP works still great after this. I did this with the last Firmware few weeks ago and it works great.
Today it works great also, everything was perfect. Than a last step: I flash the the bootloader seperately in odin. i did this the last time too and it works well. but not at this time.
After Bootloader flash, the device stays in the first Screen with Samsung Logo, i cannot go to Download Mode or Recovery. I tried a USB-Jig, but it changes nothing. The only thing you can do now is, to make a Reset with Power+Volume Down. Than the screen goes black for a second and it shows the Samsung Logo Screen again.
bad thing is: I cant turn off the device!
i remove the SIM and the SD-Card, but no reaction.
Anybody an idea? The battery was half loaded, so maybe it takes a while, before it will shutdown itself.
Mhhh, that's a bad day, i fear. But iam an Idiot, it was the Bootloader-Flash at the end, before that everything was perfect.
Maybe anybody can help me, that were great.
And sorry for my bad english.
Thanks,
Jan

No. Iam holding it about a Minute, a few times, nothing happends.

There is a hacky method to remove the back and get to the battery
https://www.youtube.com/watch?v=u1naej9BnfM
But it will no longer be waterproof
I can't think of any way to power off the phone if holding power does nothing
Have you tried resetting it with the USB Jig inserted?

Yes, i tried that too. with and without I just can turn off this thing off.
thanks for the link, but i think before i remove the backcover, i better will bring it to repair first. i got an official samsung repair center in my town.
by the way: it was the bootloader from the latest official firmware (G930FXXU1BPH6, DBT-Version).
i cannot explain to myself, what happend i done all this a few weeks ago with the last firmware without any problems.

i will now wait, until it shuts down itself, maybe that took a few hours.
if i can charge it, maybe i can than go into the downloadmode.
If you had 50% battery left, and it's just sitting on the Samsung logo, it might take days to run out
50% battery on idle with the phone booted into Android will last a day or two on its own, just on the logo is like ultra power saving mode

Found this, try holding power and volume down & up together for safe mode (Might not work if it's stuck on the logo, but worth a try)
---
Okay. This morning my S7 would not turn off, its not the edge, but basically the same phone.
You must hold down the power, the volume up and down all at the same time for about 15 seconds. (All 3 buttons).
It will go into safe mode. In the safe mode screen hit the volume button down a few times until it moves to restart.
Click the power button, as "enter" and the phone will restart.
It did a restart and I tried again to turn it off and this time, it did work. I will keep you all updated if I have any more issues.

Does Smart Switch see it?
All this is unlikely due to where it is stuck, at the logo, you shouldn't have been able to kill download mode is the thing, that is part of the hardware, nothing to do with the ROM, you 'should' always be able to enter download mode if you hold Volume Down & Home & Power at boot, not sure why it's freezing at the logo before that point
With the S5 there was an unbrick image you flashed to a MicroSD card, put that in the phone, and that took you to download mode where you could recover the phone
See if there is the same thing for the S7, I'm not sure
ok, after the phone shut down itself, i was able to go to the download mode. but only on first try. when it boots normally, it stuck again on that logo an i must wait again until it goes off itself.
flash it than in download mode with latest firmware in odin with 4 parts. power from the usb was enough to stay it on.
now it seems ok, back on latest firmware.
what a hell of an evenig, need a beer right now
You can switch your phone off with the 3 key pressing and holding (vol+, vol-, power) but your phone needs to be connected to power otherwise it will reboot.

yes, iam happy now, seems to work fine.
i think it was because the new bootloader don't work with the twrp version that was installed.
on the twrp page there is a new version especially for this firmware. it was published yesterday and i didn't see it.
so i think, after flash the new bootloader over the old twrp it chrashed the whole system.

Well if you do it again, make sure your battery is low first in case you have to wait again
Any reason you needed to flash the bootloader over the one that was already there?

an no, there's no reason to replace the bootloader, i only did it to make the whole flash "complete".

How'd you managed to power it off? just waiting?

TWRP seemingly bricked my pixel

So I was trying to make a backup with the latest twrp and I got this error code: createTarFork() process ended with ERROR=255.
I figured, to hell with it I'll reboot. Twrp asked if I wanted to install the twrp app, I said no. Screen goes back, never to turn on again. No button combo holding for any length of time helps. Bummer, right? I was running DU at the time.
Now I'm worried about the RMA, I hope they don't deny me after they get it back into the warehouse.

Does anything happen when you plug the phone into the wall or into the PC?
Have you tried just holding down power for a while?
are you on beta hardware. i noticed today my phone was unresponsive installing twrp it would go black and disconnect from pc. what i had to do to get it to turn back on since it stayed lik that even holding the power button for a while was just hold the volume key and power for a couple min down and power if that dont work try volume up and power just random pushes to get the phone it will go to some debugging screen then just holding buttons till it restarts

I've tried every button combo. Plugged it in to wall overnight and computer. No response. Makes me paranoid about twrp for pixel because I was rebooting from there, but then again it doesn't seem to be a big problem in the community

I also had the same situation go on as well. I'm not sure what's is happening but when I boot TWRP the thing just becomes unresponsive and a black screen. I had to hold the buttons for nearly 30 seconds before it worked. Pixel isn't a friendly device to mod. :-/

Yes I was using twrp, I was flashing test build. But it put me into a loop. U got a black screen, and if your computer won't even recognize it , you may be out of luck. I have been using rc2 I know it's not great for restoring backups, but it works good for everything else
That is so strange. I have never come across this issue before. Unfortunately, if you can't seem to get your PC to recognize the device, I don't think there's anything you can do. I guess we will have to be wary about using TWRP. I haven't had any weird issues myself with TWRP but I know others have. Here's hoping google will honor your warranty. I think they will, I don't think see them spending the time to look into what caused your phone to die so I think you'll be able to get a replacement without much hassle.
If you wouldn't mind, please keep us updated.

Samsung note 20 ultra 5G U.S model

Hello everybody.
I am trying to get to recovery mode but I did not succeed so far.
I looked at a few sites and youtube,too.It was advised to insert the earphones and to press the on/off and vol+ at the same time.I tried to press on the the on/off and vol+ and tried after the on/off and vol- but nothing happened so far.
Does anybody know what is the REAL WORKING WAY to get to the recovery mode?
Thanks a lot,
Arye
Press and hold Vol + and Power button until you see the Samsung logo, then release both.
No need to plug in anything.

Ahh yes... the Steve Jobs "you're holding it wrong" comment comes to mind.
Gotta hold both buttons until the "Samsung", or carrier logo shows up. Then release.
I don't have carrier branding, so I forgot most will see their carrier logo instead of the Samsung logo.
If you're releasing during the device startup logo, that's too soon.

Probably got the China model that why it doesnt work. You need to plug in the usb c cable to computer then do what others mentioned.
