Hi folks ,
I am running CM 7.1 on my SGS2 , all is fine , but I fumbled my way through the root process due to only having limited access to a poorly specced PC , and an awful internet connection at work ! (Mac user at home) this was a real nightmare ,and I'll spare you the gory details , but the result was this


*Flashed an insecure Kernal with Odin ,with a view to Rooting , was unable to run the root app (like I said long story !)

*Found a "pre-rooted" kernal on XDA devs that seemed appropriate for my device , so flashed that with odin

All worked fine , I was rooted !

I used CWM manager to install CWM recovery , which appeared to work , but I could not boot into it ! , so in the end I installed ROM manager and installed CWM via that - this seemed to work ,

I then installed CM7 Nightly via ROM manager , and all is good in the world , EXCEPT the yellow triangle on boot up (not a huge problem , but I'd prefer to lose it)

Can anyone tell me how to lose the triangle ? - I assume I have to flash a Kernal via Odin , but which one (considering I am running CM7.1 & CWM 4.0.1.5

Any help would me much appreciated ! thanks

to loose the yellow triangle you cab either use a USB Jig or reflash it with CF - root (not need for you but alot easier, for future reference) Anyway, to get rid of the yellow triangle you need to reflash your stock kernel (You won't loose root)

Hope this helps.

EDIT 1: CM 7.1 is out, i never knew that, thank you.

it is possible to get rid of it using a software solution but considering the nightnare you just had it might not be viable for you, there are some instructions over at XDA however that will not reset the flash counter, the easiest way would be to get the USB dongle for about £5 that will fully reset the counter

Hey thanks for the quick replies !

Just to clarify , (probably what I should have asked in the first place !) The original Samsung Kernel WILL be OK with CM 7,1 then ?

Thanks again.

Since you have CWM already. Check whether it have flash kernel option or not. If yes, flashed the original kernel till it was booted and the triangle was gone. Used CWM flash kernel again, this time you flash CM 7 kernel so you CWM recovery will worked for you.
If your CWM without a flash kernel option, then you used DarkyROM tool which can be downloaded from market.

Brilliant , thanks ! But ......

(this just gets worse !)

I have forgotten what Kernal I started off with , I didn't make a special effort to remember it as I left the file of the Signed kernel on my desktop at work - I now find a collegue has not only deleted it , but emptied the recycle bin too.

Now when I look at the kernal in "about phone" I get

2.6.35.7-g1e46077

Is this the end of the world ? is there any way I can find out which Kernel to flash ?


Thanks !

Have a look for your service provider here: http://forum.xda-dev...d.php?t=1113928

It will most likely be one of those kernels, that's if you bought it on contract,
If you bought it unlocked/debranded then i can't help you.

If your from the UK, these are our networks that sell this phone
3 Network (where i got mine)
o2
Orange
T-mobile
Vodafone

Good luck.

p.s Sorry if this does not help you.

LOL !! Erm , that went well ....

OK I chose the o2 Kernel (I am 100% sure this was the actual one I needed , KF3 )

Downloaded it to the Card , and flashed it from Darky2

All seemed to go OK , and I booted up without a yellow triangle - but that was it, didn't go any further than that , just a boot loop with the Samsung I9100 screen , and a black screen. Tried wiping etc. all to no avail !
I figured I didn't have anything to lose ,so looked around on the net , and I stumbled on this guide
http://www.techofweb...nding-sgs2.html

So, I downloaded the UK o2 .tar from that page and flashed it via odin

This brought the SGS2 back to life , but not rooted obviously , to be honest I am just glad its still seemingly alive ! I think I'll leave it for a while and worry about rooting again when I get time.

One last thing though, As said I am sure the "XF3" was my orignal Kernal , (might have been KF3 ? ) It was definately an O2 UK device though -The file I have flashed is XWKDD - Everyhting seems to work fine though , is there anything I need to worry about here ?

Thanks for all your help on this

I was assuming you were going to flash the Kernel through odin in the first place, but there is nothing to worry about from what i can see,

if i were you i would Use CF- root in future, it's 1 step (Flash via odin) you have instant root and CWR
Make sure you use the CF root kernel specific for your stock kernel though.

I will do that -

Half the problem is the crap PC I have at work here ! for some reason once I have Kies installed on it , it slows down to a snails pace and the internet connection drops , so I have to install Kies everytime I want to use Odin,and then when I think I won't need Odin anymore ,or I need to use the internet for work purposes I remove it (seriously, its been installed and uninstalled about 3 times today !)

I must buy myself a Windows Laptop for this stuff !

Anyway thanks for you help on this !
