Step 5: Connect your device to your PC and start Odin3 v1.83. If you installed Samsung Kies correctly, you should see the box in the top left corner of Odin underneath where it says ID:COM should be Yellow and displaying the name of a Com Port your device is connected to.
I cant get there, it doesnt go yellow. I have kies installed correctly, not sure whats wrong

Did you make sure you are in Download mode, and the drivers were installed correctly? Also, did you make sure you added the kernel file in the correct section? (without ticking any unnecessary things)

---

Yes.
Now it wont switch on.
Firmware upgrade encountered an issue. Please select recovery mode in Kies & try again.

---

Did you tick the PIT box?
Edit - sorry, just reread, you haven't. I hope..

---

No i didn't. I restored the original firmware but it still wont turn on normally.

---

Did you have kies running in the background? Make sure you end all kies applications - end process

---

Nope had shut kies.

---

Could be a cable failure. Try a different USB cable.

---

I only have 1 cable. I restored the kernels and it went green that it worked. But my phone doesn't work.

You can get a new USB cable for a couple of bucks. I've got like 6 due to all the devices I've had over the years, and 2 of them are bad. They don't last forever.

Managed to restore device using tutorial i found on google androidcute.*com/install-android-2-3-6-gingerbread-for-samsung-galaxy-s2.html

---

after restoring i decided to give rooting another go.
all worked out fine, i installed rom manager after and it keeps rebooting itself after every few mins
i have cpu tuner installed too i also restored the original kernel after rooting.

ROM Manager is the devil. I don't think it plays well with CWM. How are you rooting? If you root using a CF-Root kernel, it will auto-install the CWM app, which I believe does everything ROM Manager does.

I used S2 Root, i uninstalled rom manager though.

Last time I had this issue, it was some app I installed, but I couldn't figure out which one. I flashed back to stock and was more selective in which apps I chose to reinstall. I've also made sure that all the apps are on phone memory instead of SD card as there was some speculation flying around that this could also contribute to this issue. Haven't had a random reboot in months now.
