Getting rid of that pesky warning triangle during boot

It is definitely possible to remove that pesky warning triangle during boot when running a custom kernel, though you should be well aware that this method does NOT reset the custom kernel flash counter. The steps are not complicated, but they aren't easy either, so read well.

(1) Make sure you have CF-Root flashed (see the first post). You must have the "CWM Manager" app available.

(2) Make sure you have the same version of CF-Root extracted until you have the zImage file. (ZIP --> extract --> TAR --> extract --> zImage).

(3) Push the zImage file to /sdcard . It must still be called zImage !

(4) Find an original Samsung signed stock kernel (preferably from the same stock firmware you have, but it's not terribly important)

(5) Reboot into download mode (adb reboot download, or boot the device with home and volume-down pressed)

(6) Fire up ODIN, and flash the Samsung kernel

(7) Boot the device with the stock kernel. CWM Manager will still be available.

(8) Start CWM Manager, select Flash Kernel, and select the zImage from CF-Root you previously put on your SD-card. The kernel will flash and the device will reboot.

(9) You will now notice you no longer have the warning triangle during boot, but you are actually running CF-Root with all it's goodies!

(10) In the future, if you only use the Flash Kernel option inside CWM Manager instead of ODIN, the triangle will not return, neither will your flash counter increase. But keep in mind, that CWM Manager can only handle a direct "zImage" if you are NOT running a kernel with full busybox support (this is currently needed for flashing kernels out of .TAR and .ZIP files)

Hi guys,

I picked up a SGS II the other day and decided to extend my development of the SGS boot screen MOD to it and was able to port it the same day as not much as changed in the way the param.lfs operates. I know this works just fine on the English i9100 in which the param.lfs calls for logo.jpg but if it fails, you can always re-flash a stock param.lfs to restore the boot screen. I have written this for (i897, i9000, T959, T959v and now i9100). Per XDA's rules, I'll just attach the RAR package as an upload at the bottom of this post.

If you appreciate my work, just tap THANKS or DONATE me a drink or two if you are feeling generous. Here is the read me in case you don't want to open it with an additional text editor:

Code:

Brought to you by MOBILETECHVIDEOS.COM and CONNEXION2005 of XDA-Developers.COM

If the instructions below don't make sence to you,

JUST DONT DO IT!

To change logo again, repeat whole process!

=========================================================

| 2. Boot Phone into Download Mode	|

| 3. In Odin PDA select "SGS2_custom_param_lfs.tar"	|

| 5. Boot Phone Normally and reconnect USB (dont mount)	|

| You will have a garbage screen! DONT WORRY!	|

| 6. Rename the Picture you want to use to " logo.jpg "	|

| 7. Run "MobileTV_SGS2_BootScreen.bat" from PC, follow |

| instructions. Keep phone screen ON, allow SU request. |

| 8. Reboot and Enjoy!	|

=========================================================

If Odin hangs on the flash reboot odin and phone into download mode.

YOU WILL HAVE SOFT BRICK!, just keep forcing the params file.

NO NEED to go back to stock!

NOTE about custom images!

If it helps you can follow this older video I made for all the original variants when I first developed this MOD. I'll make a newer video to show it off soon. For now you can see it first hand on my phone by checking out my Lite'ning 1.4 Review on the Youtube channel. I highly recommend you subscribe to that channel as well since I will be popping out lots of SGS 2 reviews and tutorials.
