Recover Samsung Galaxy S2 from a black screen
If your phone doesn't want to boot up again after the update, it gets stuck in a black screen, follow this tutorial where we root the Galaxy SII with Odin and put an official Samsung Android 4 ICS on it.
|
|
 |
|
|
|

|

|
 |
1.
|
|
|
In order to rescue your phone, you will need: micro USB cable, Samsung Kies installed on your computer, Odin program to root the phone, rooting file and original Samsung Android 4 (ICS) image file.
Click here if you don't have Kies for Samsung installed and click here to download the ZIP package with Odin, rooting file and ICS image.
When you have all the things installed, downloaded and ready, take your Samsung Galaxy SII and press center/home button, power button and volume down button all at the same time and hold them for about 10 seconds ...
|
|
| |
2.
|
|
|
... you should now see the Warning!! screen.
Before we continue, it's not recommended to "flash or root" your phone as you may lose warranty or harm your phone even more. We cannot be held responsible if something of above happens. Action was performed on Galaxy SII stock phone and it won't work on carrier phones like TNT and similar.
If you still want to go through, press the Volume Up button to continue.
|
|
| |
3.
|
|
|
Connect your SII using microUSB cable to your computer.
|
|
| |
4.
|
|
|
Unzip the Dreevoo_com_odin_root_and_ICS.zip you downloaded and start the Odin3 v.185.exe program you find in Odin folder.
|
|
| |
5.
|
|
|
In Odin you should now see a yellow field with similar entry as in my case. If you don't see yellow field then you probably don't have Samsung Kies installed on your computer. Download and install it then plug out USB cable from your phone and plug it back in. Yellow field should now appear. If not try closing and opening Odin program.
|
|
| |
6.
|
|
|
Let's now "root" the phone, click PDA ...
Rooting a phone means, gaining access to phone system files and having ability to change things you normally could not.
|
|
| |
7.
|
|
|
... and choose the CF-Root....tar file.
You can find the file in ZIP document you downloaded earlier.
|
|
| |
8.
|
|
|
Click Start and off it goes!
|
|
| |
9.
|
|
|
If everything went according to plan you should see a green PASS! field.
It takes a couple of seconds for the procedure to end.
|
|
| |
10.
|
|
|
Your Galaxy SII should now reboot and there should be a yellow warning sign meaning your phone is rooted and custom android ROMS can now be added.
But your phone is probably still in "black screen of death".
"Black Screen of Death" is a synonym for the unresponsive state of your phone. It's similar to "Blue Screen of Death" known from Windows systems.
|
|
| |
11.
|
|
|
Let's now put a stock Samsung Android 4.0.3 onto a Galaxy SII. In order to do that, we need to put the phone back into Download mode.
Again, press center button, power button and volume down button all at the same time and hold them for about 10 seconds ...
|
|
| |
12.
|
|
|
If you are again sure you want to proceed, press the Volume Up button ...
|
|
| |
13.
|
|
|
... phone should still be connected to your computer via USB cable.
|
|
| |
14.
|
|
|
Again in Odin program, click PDA ...
|
|
| |
15.
|
|
|
... and choose the ICS image .MD5 file that was included in ZIP file you downloaded earlier.
|
|
| |
16.
|
|
|
Click Start and wait for it to finish its business.
|
|
| |
17.
|
|
|
It can take a minute or two ...
|
|
| |
18.
|
|
|
... and if everything went smoothly, you should see a green PASS! field.
|
|
| |
19.
|
|
|
Your phone should reboot automatically ...
|
|
| |
20.
|
|
|
... upgrade the system ...
|
|
| |
22.
|
|
|
... and load successfully with a brand new ICS 4.0.3 Android system, with all of your pictures, videos, contacts and other stuff still in tact!
If you get stuck somewhere during procedure click Comment and tell us what is up.

Hey atvasanth welcome to Dreevoo.
First, if you already haven't, try this:
- turn off the phone
- remove the battery
- put the battery back in
- connect your phone to the charger
- turn the phone back on
If this doesn't work, try resetting your phone to the factory defaults, but mind all the data will be lost so you need to back it up first. This is how you do a factory default reset on Galaxy S2:

If non of the above works, let us know. And don't worry, we will fix your phone one way or another.

| Sounds like the actual flashing didn't go all that well. I would suggest you to try and do what you did, following the instructions one more time. It should be ok, if not, again let us now |

Another possible cause of problems might also be faulty battery.
Before doing upgrade procedure please be sure that your battery have enough charge.

Hey liawuzier,
it could be the battery, but I'm still considering other options. I'll get back to your asap.
p.s.: 100 tokens have been added to your Dreevoo account for posting a question on the forum.

Also make sure that in Step 5 in Odin you should see a yellow field. That is how you know the phone and the computer are connected.
Can you also explain a little bit more in detail how it is failing. Do you maybe see any error message?
