[Q] Samsung gt-s7562 duos won't go into download mode

Hi everyone, I hope someone can help with this.
I have the Galaxy S duos which has problems with connecting to data for both sims. I am trying to flash a later formware in the hope that it is more stable. I have the firmware, kies, odin and drivers.
The problem is that the phone will NOT go into download mode. When I press and hold the vol down/menu/power buttons I go into a Factory mode instead of download mode - the following options are available in this mode:
Full Test
Item Test
Test Report
Clear eMMC
Reboot
When I press and hold the vol down/power buttons I go into Recovery
Is there anything I can do to get into download mode??

i face the same problem . . . it connected to chinese box , it was a high copy phone

100% solution
just press and hold volume down+home+power at a time
and when device vibrate just leave all keys
then download mode will appear then just click on volume up
but its important to leave all key when device vibrate
thanks

Same here. I don't know what to do!

I have the same problem with my phone , but when I checked the IMEI of the phone by site imei.info, I saw that the phone is a copy ...

Step 1 – Turn OFF your Galaxy S Duos.
Step 2 – Make sure your phone is unplugged from the USB cable.
Step 3 – Now press the following keys on your phone: Volume Up + Home + Power.
Hope this helps......bcz it works for me and all other, and might not work in some cases like......Replica version etc

its not original its china high copy if you choose lear emmc it will be format try it if its dont work with you search for a firmware to youre mobile .......
anyhelp told me

PRESS POWER+VOL DOWN+HOME keys after it vibrates TAKE YOUR HAND FROM POWER KEY and keep pressing on VOL DOWN AND HOME......works for my old phone

Reboot only in my case

its MTK phones sir...i'm sure 1000%
this is good firmware for this phone(tested)

HELP: stuck in Smart Switch mode

Need serious help. My Samsung Galaxy S6 Edge is soft brick I think.
I was able to go into recovery and download mode (VOL DOWN + POWER + HOME keys).
Now it's currently stuck in Smart Switch mode.
I cannot take out the battery so the phone cannot be switched off that easily.
Does anyone know how to get out of Smart Switch mode?

Press 'Power' + 'Home' + 'Volume -' for about 30 second, phone must restart that way. Just reflash your phone using latest Odin 3.12.7 (and latest Samsung USB drivers) to latest stock firmware for your model (you get it via SamFirm) then flash CF_AutoRoot & TWRP and do what you want!

I figured out how the DOWN POWER HOME button works only while usb is connected.
I can now use odin.. but now I get NAND failed during flash

So can be just hardware issue, for example eMMC broken.

check drivers or change usb port on pc/laptop

Yes you can check also on another cable or/and another USB-port or even on another PC... But I don't think so that help... Did you tried like I told HERE?

could not do normal boot, invalid kernel length
Click to expand...

, then i connected the phone to my computer it constantly restarts and says the same thing
could not do normal boot
Click to expand...

, can't enter into recovery mode, c'ant enter in download mode, even my pc and odin doesn't recognize the device at all, please help I can't afford a new one.
Thanks in advance.

Just flash stock rom with odin, conect to pc pressing vol + and vol - to get download mode

It doesn't react with + - buttons, that is why i can't flash it

What is the last OS you are running?
If the phone keeps restarting, first connect the phone to your PC via USB cable.
Then
1. Keep Vol+ and POWER pressed.
or
2. Keep Vol- and POWER Pressed.

Thank you but it seems that my motherboard is damaged
Thank you but it seems that my motherboard is damaged

I do not think it has been damaged, try pressing vol + vol- boot at the same time a couple of times and then the third release the vol + i the boot and it will restart in dowload mode. then flash with odin each of the partitions of an original rom.
good luck

Samsung Galaxy A7 (2018) - No Download mode or Recovery and infinite bootloop

Hi,
Recently i was trying to apply another rom to my Samsung Galaxy A7 2018 edition and i am stuck in an infinite bootloop. I cannot enter download mode with the Volume Down and Power keys and the only thing it does is showing the logo of Samsung every 5 seconds and restarts. I have tried to built a usb jig with 300k resistors and still does not boot up in download mode to flash with odin a stock firmware. Also i left the battery to drain and now it is turned off,but when i plug in the usb cable and power it up it still goes into infinite loop. Any help?

I was trying the Android 10 Magisk root for A750F and was greeted by a similar situation after ODIN rebooted my phone after flashing Magisk image.. Anyways, don't panic, try all combination of buttons. vUP,vDN,PWR or vUP,PWR or vUP,vDWN while connected to usb.. It wasn't working for me too but i tried all combinations and it landed me to download mode where I flashed the stock rom

just press those button and connect to usb

im glad i read his, had just the same issue while flashing wrong twrp on A750FN .. yihey thx budies

how did you solve this issue.
---------- Post added at 06:54 AM ---------- Previous post was at 06:45 AM ----------
which button combination helped you. I having a similar issue. can not enter download mode.

Solution that helped me
Just Press the volume plus + volume minus + power button at once. Once the phone reboot black screen appears, Leave the power button and keep pressing the volume plus and volume minus button. It will redirect to the download mode. and reflash the room using Odin. Only use official sammobile rom file as other files may be corrupted. The issue may arise. The problem is in rom.
If any issue query me at : [email protected].

try this bro

I have tried keeping all 3 buttons (vol up + vol down + power), tried holding vol up + vol down and then connecting to my PC (nothing happens, I always see the same screen (SAMSUNG Galaxy A7 Secured by Knox and Powered by android underneath)).
Tried vUP,vDN,PWR or vUP,PWR or vUP,vDWN while connected to PC via USB.
Tried vUP,vDN,PWR or vUP,PWR or vUP,vDWN while NOT connected to PC via USB.
Phone sometimes reboots but always gets into the screen I mentioned above.
Odin, obviously, doesn't see the phone either.
Also, adb devices command deosn't show the device in the list.
Anything else I should try?

Ah I solved it, and nobody mentions that you have to be SUPER quick!?
So you hold down vol down + power button and keep the USB cable at hand and the millisecond your phone reboots, reeeealy quickly release vol down and power and quickly afterwards press vol down + vol up and again quickly plug in your USB cable, if you did it before the Samsung logo appears you will get into Downloading... screen.

Question my Galaxy A12 won't boot to android or download mode help me pls

so I just tried to install unofficial TWRP 3.5.0 on my Samsung galaxy a125m and everything went fine, Odin said done. Then I just tried to start TWRP by pressing power and vol up and it didn't start, so I thought I might have done something wrong and rebooted to download mode and flashed it again, Odin said done, then I unplugged the USB cable and now it won't boot, neither to the system or recovery, even to download mode, it did enter download mode a few times before but I pressed the wrong button and had to cancel and enter again, now it won't even enter download mode so I can't flash stock rom to fix bootloop... pls how can I solve this I'm desperate
when I try to enter download mode by pressing volume up + volume down it just shows up charging mode without any numbers, then it turn on and shows Samsung logo, unlocked bootloader warning screen, and the Samsung logo again, but then just restarts and repeats all again...
when I try to press volume up + volume down + power, nothing really happens...
someone help me please

You need to keep both volume up and down pressed, then plug in the charging cable. It should enter download mode, no need to press the power button like in older samsungs.

yeah I did that a lot of times, it used to work now It doesn't anymore
in this video you can see what's going on, I'm pressing both volume keys and nothing happens
Your browser is not able to display this video.

Is the cable plugged into a charger and on?
Have you considered that your volume buttons may not be working?

Same hear

Try attaching your phone to the PC, and then pressing volume down + power to reset the phone, (for about 7~8 seconds) then immediately press the volume down and up buttons, that's how I recovered from it. Tell me if it worked

Please help it dosent worked
No pc detection
No download mode
No recovery
No charging

Hello, unfortunately in these cases the only solution is to enter download mode, check if any button is damaged or if the cable works and if it is well connected, press the buttons harder, hold down the volume up and volume down buttons at the same time , by pressing the strong buttons, for about 6 seconds and then connect the cable. If you don't try another cable to see if that's the problem there is no other solution as the phone is not recognized by an app that can put it into download mode when turned off the solution is the one I already told you about. I hope you have fixed that problem. Sorry for my bad English.

I am having a similar problem with the Samsung A12 SM-a125u
I never could enter into this "Downloading mode".
I tried flashing the stock ROM through ADB with fastboot, and I have another problem that I've never seen before: ADB can see the device while in recovery mode, but fastboot can't. And so it won't allow me to flash the ROM and I don't even know how Odin is supposed to help yet; I think I needed to enter Downloading mode for that, but I can't get into it.
I'm working on this phone for a friend who was given it because his friend's mom doesn't remember the password to it. Does that matter? It's worth noting that because of that I cannot get in to turn on OEM unlocking or dev mode, but idk why that would come into play in recovery mode. Also, the model indicates this is an AT&T phone, and tutorials online have acknowledged this model in their "applicable models" list at the beginning of their tutorials, but I know that carrier phones can cause problems all over the place (stop buying carrier locked phones people!); is this a problem?
How the heck do I flash the stock ROM to this this?
