Stuck on boot screen after using Mobile ODIN

[henryronny]

Hey so after rooting and updating to Jellybean I tried to get cute and flash NeatROM using MobileODIN and the process started but my phone is just stuck on the boot screen with yellow triangle. I was using the SiyahKernel S2-v6.0beta5 but thats about as technical as I can get.

I can get into download mode but not into recovery mode otherwise I'd perform a wipe/factory reset

Call me a noob all day long but how do I get my phone back to life? Is Heimdall & stock JB the best way?

I've got all the 'version' info scribbled down but don't know if that would help answer any questions

I live in a mac household which is why I didn't use Odin on the PC to flash the ROM

Any help very gratefully received

Hi henryronny. I moved this to the All Things Root forum for you where the rooters can see it.

I don't have this particular model of the GS2 or experience with Heimdall, but if you can get in download mode loading stock sounds like a good option.

Hope you can get it straightened out soon.

Ahh, I see the problem. You should not have flashed Neat Rom using Mobile Odin. You should have flashed it using ClockWorkMod Recovery.

If you have the time, go borrow a friend's pc running windows and install the desktop version of Odin.

Download a 4.1.2 Firmware from Firmwares | SamMobile (You need to have an account to download, creating an account is free). Also download the .TAR version of Siyah v6.0beta5 and TriangleAway from http://forum.xda-developers.com/showthread.php?t=1494114 .

I guess you already know the process, but if not, continue reading.

PHONE
1.) Boot into download mode
2.) Plug in your device

ODIN
1.) Open Odin; if the device is recognized, a box will light up yellow, it should appear like this.

2.) Click on PDA and find the firmware you have downloaded.
3.) Click Start and wait for it to finish.
4.) Set up your phone and reboot again to download mode.
5.) Click PDA again, and this time, find Siyah and press start.

PHONE
1.) Install TriangleAway.apk by going to My Files > Where you placed it. Be sure to check Unknown Sources at Settings > Security
2.) Follow the instructions.

There you go, you should have a fully functional phone again.
