I've just installed Android 4.0.3 ICS onto my Samsung Galaxy Note with 2.3.6. The installation was done by wifi via official installer. I did not download anything specifically, just got a popup with something like "Do you want to upgrade to 4.0.3?" After answering 'yes', it downloaded some files over wifi, and restarted the phone.

But the restart didn't go well. I can see the initial Samsung animation, but after that the text "Samsung" keeps flashing in the center of the screen and nothing happens. I left it for a couple of hours - no changes. I tried rebooting and even remove battery - the same thing, it does not boot. I have never rooted the device or replaced the ROM.

What can I do? How can I enter recovery mode or something? I tried to enter safe mode by tapping menu button while booting - didn't work.

forum.xda-developers.com/showthread.php?t=1658440 enter recovery and try to wipe data then restart. what you describe is a bootloop after rom update, wiping your data should work. hope you made a backup! –  svarog Jun 29 '12 at 17:06

I think if he was rooted the OTA kies wouldn't update –  svarog Jun 29 '12 at 17:22
    
Holding Volume Up + Home + Power buttons while turning the phone on should boot it into recovery mode, where as @svarog suggests you can do a wipe. –  Chahk Jun 29 '12 at 17:33
    
@svarog, jlehenbauer, Chahk: Thanks for your help. I wasn't rooted. Successfully entered recovery mode, then wiped all user data. Then rebooted. Didn't work, the same bootloop occurs. What should I do next? –  Denis Golomazov Jun 29 '12 at 17:44

I would suggest flashing the stock ICS (or Gingerbread, if you prefer) ROM via Odin. Full instructions here.

  1. Get the official image from http://www.sammobile.com/firmware/ (search for "N7000" and select the download for the appropriate region.)
  2. Download and install the USB drivers (for 32 bit or 64 bit Windows)
  3. Download the Odin tool.
  4. Extract the contents of the downloaded ROM and place it somewhere on your PC.
  5. Reboot the phone into Download mode (Volume Down+Home+Power buttons.)
  6. Run Odin and connect the phone to the PC via USB. Odin should recognize the phone by showing a yellow [0:COMX] sign in one of the "ID:COM" boxes.
  7. Select the "PDA" button and browse to the extracted TAR file.
  8. Make sure that only two boxes are checked in odin - Auto Reboot and F.Reset Time.
  9. Click "Start".

This should refresh the phone with a brand new OS and all prerequisites.

It worked! Thank you very much! –  Denis Golomazov Jul 1 '12 at 18:16

With the phone off, press power then let go and press and hold home and menu while it boots up.
