[Q] Samsung Galaxy S2 i727 ICS Root

I've recently upgraded to ICS, and am now trying to root my newly upgraded SGS2 phone. I am stuck trying to enter the Recovery Mode. I've searched online for guides on how to root, and many individuals instruct to hold the Volume Up + Volume Down + Power button, then when the SAMSUNG logo appears, let go of the Power Button. The recovery mode menu does not appear. Can anyone help?

Have you entered download mode and flashed the custom recovery through Odin? All this info can easily be found in the all in one guide that is stickied at the top.
More info is needed. How did you upgrade? Was it a one click method?
Edit for link: http://forum.xda-developers.com/showthread.php?t=1427268
Here is your link for the instructional thread. Please read this carefully. Everything you need will be on the first page. Any reason why you wish to root? Only reason I ask is because you are a new user.

Regardless of which recovery you have it has to come up.
Turn the phone off, now hold all three vol up/down and power once phone vibrates let go off power, don't wait for the logo

[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??

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?

You are hardware bricked, your Samsung has a hardware component that, once tripped, will not let the device boot.
You tripped the "fuse" by attempting to flash TWRP or some other custom software not approved by your manufacturer or carrier.
Next time, do better research before attempting to modify your device.

Did you try Vol- and power button If it doesn't work the volume up and down and power button

Its volume down+home+power if the device has a home button.
Or volume down+power if the device does not have a home button.
Or a USB jig
If none of these work to get the device booted into download mode, the only options left are a JTAG/Riff/Octobox service or replace the motherboard.

[NEED HELP] Bricked my phone with low chance of any recovery

I need help urgently. I tried to change the splash screen of my Samsung Galaxy A51. I downloaded a custom param tar file, placed it in my downloads folder and used this command in adb shell to replace the older one. I did back up my old param. But there's no way I can restore it. Now, my phone when I try to start it. It doesn't even seem to turn on the screen anymore. I hear the phone vibrating every 2 seconds so I assume it keeps rebooting. I tried to enter download mode but I can't because samsung made it that you need to go into the recovery first, so I tried to go into the recovery but nope, it keeps vibrating and it's not responding to whatever I do. Is there still any hope for my phone? Thanks in advance.

Hello, I had this problem too. My phone also stopped booting into anything, even in TWRP.
For me, the resolve was to make the phone force reboot by holding power button and volume down, then immediately try to enter the downloading mode by holding volume buttons, when the screen turns off

and then you need to flash your device with your stock ROM

I understand you, that you cannot enter the recovery, but for me this method worked

I managed to solve it, the problem I had was that I was unable to boot into download mode. Because I have a samsung galaxy a51 and I did not know how to enter it. The last phone I had was a samsung galaxy s7 edge, back in the old days it was easy to enter download mode, just hold volume down, power button and home button. Now for some reason I need a cable connected to my computer and then hold volume up and down simultaneously. After I figured out how to enter download mode I flashed stock rom and phone worked again.
