Should I reflash the original kernel after rooting? - Galaxy S II Q&A, Help & Troubleshooting

Hello everyone,
Am asking the above question because while backing up and restoring
my current ROM using ROM manager, the phone (Galaxy S2) restarts with
an exclamation mark above the android man (plz see attachment below).
It gets stuck at that screen and am forced to again restart the phone
after which the back and restore process goes smoothly.
1) My question is will flashing the original kernel solve the above problem?
2) Also will I be able to install apps requiring root permissions after I've
reflashed the original kernel??
3) And will I be able to restore my backed
up ROM if I've reflashed the original kernel??
Android: 2.3.3
FW: XWKF3
Please help

It should and it will get rid of the yellow triangle. just follow instruction in the second post of the thread from chainfire rooting thread.

Thanks for replying. Will it also solve the 2nd and 3rd queries??

2. yes, because your phoe will still be rooted.
3. yes, but you will lose any new apps that you have downloaded in te meantime because you are using a back up made from an earlier version.

Flashing the stock kernel via ODIN in Download mode will remove the Yellow Triangle.
After flashing stock kernel, you lose ROOT, so no, you cannot use applications that requires root.
If your kernel comes with CWM app, you can use that to install a rooted kernel again without incurring another tick at the Custom Binary Counter, and because of that the Yellow Exclamation will not appear.
Backing up with ROM Manager should not invoke the wraith of the yellow exclamation, and neither should restoring either, since it doesn't use Download mode. Are you sure you were using clockwork recovery to restore, and not ODIN to flash?
If the attachment is the blue triangle and not yellow, then it is not the same as the one that custom binary counter triggers.
That looks like 3e (Samsung's recovery)

Hi LiFE 1688,
I rooted my phone with an insecure kernel using this method:
http://forum.xda-developers.com/showthread.php?t=1125414
Then I downloaded ROM Manager, flashed CWM then backed up
my ROM using the option "Backup Current ROM". For restoration
purpose, I used "Manage and Restore Backups" option within
ROM Manager.
The problem is when I try to restore or take another backup
with ROM Manager the device boots up with the exclamation
mark (as seen in the attachment above) and it gets stuck
there.
Then am forced to shutdown and restart my device after which
the backup or restoration process goes smoothly. My question
is how do I remove that exclamation mark which I get after
my device reboots for back/restore purposes.
Note: The yellow exclamation mark which is shown underneath
the Samsung start logo also persists so it would be great that
the solution also removes that yellow exclamation mark as well.
Thanks for reading.
Please help

[Q] Problem using ROM Manager Premium

I have just installed Rom Manager Premium, and when I click in the "ROM backup option " in the menu the phone reboots, than appears a small android and a white triangle with an exclamation mark inside and stops the process. If I take the battery out and put it again, the phone restarts than the backup process is completed.
Someone can help me about this issue ??
Regards
Richard
Clockwork Recovery and ROM Manager are not so compatible with each other.
This has something to do with which kernel you are using. Try switching to another kernel instead.
Or use the CWM app from Chainfire's kernel. It works perfectly for me every time.

Stuck at yellow triangle..

Hi,
I've flashed the official MIUI ROM. And I've tried to replace the standard arial.ttf and arial-bold.ttf in system/FONT with a other font but with the same name. That didn't work as planned so I changed it back to the original fonts which I backed up before. The strange thing is, when using the standard theme, the font does not work in settings menu e.g. So I decided to delete the arial and replace it again, but after deleting the fonts the phone shut down and now it's stuck at starting up, it shows the yellow triangle and it just stays there.
So.. it won't start up because it's missing the arial font.
How do I fix this?
Thanks in advance!
Reflash the ROM.
Either via Odin or CWM, w/e form the ROM comes in.
Do I have to do all the wipes again? As in data/factory, cache, dalvik and format system?
If you flash the same ROM you had before, you usually do not have to do the wipes.
That worked, thanks for your help.
To bad that tutorial on how to change font in MIUI brought me to this. But thanks again.
Not a whole stock ROM, only a stock kernel.
Then flash your custom kernel back via an app running on the phone, that doesn't trigger the triangle.
Check my kernel post (link in sig), there is a short and quick way described on how to do that.
Nope, if you flash via CWM or an app, no triangle.
The yellow triangle is only triggered when you flash a non-stock kernel via Odin and downloadmode.

[Q] clockworkrecovery isn't working.

I just rooted my phone using superoneclick, flashing insecure xwkdd kernel then flashing stock xwkdd kernel to remove yellow triangle. after purchasing Rom manager from the marketplace, i used it to flash clockworkrecovery to my phone. it then displayed that my current version was 4.1.0.5. I believe it is the latest.
Next was to boot into recovery so i could install cyanogenmod from my sd card. however when i appt into recovery from Rom manager, it would go int o recovery but while loading it will show some message about file certificate and not able to read whole package. So all im left is to reboot back to normal. I can't get tos the clockworkrecovery page. even when i do utter manually and use vol up + home + power, it goes to stock recovery. why!!!¿¿ Help please as im starting to wonder if the firmware issue.
Before anyone jumps in here to help you out, I'd just like to remind them of your last thread which looks rather familiar, with a slight difference:

ok guys i odin the stock rom with root, how in the heck i get into recovery mode and install cm7? i tried rom manager and it didnt work any other ideas?
Rom manager does not work correctly on stock. (It will work once you are on cm7.) You need to install a kernel that contains ClockworkMod Recovery. If you install the kernel with Odin or Heimdall, it will increment the flash counter and cause the initial I9100 boot screen with yellow warning triangle. If this is a concern to you, use the Guide linked in my signature to avoid that.

[Q] yellow triangle after having flashed bootloader via Odin

Hi,
I've rooted my device via ODIN (it works fine) & then I wanted to install CMW to be able to install the latest Mokee KK
Unfortunatelly I've checked bootloader & selected the zip file of CWM-KitKatCompatible-i9100 ... and clicked start. Yes I know never flash a phone when you're tired ...
Then my phone never wanted to reboot in the previous OS and got stucked on the boot screen + a yellow triangle
I've tried to flash CWM (it worked) & I've boot into recovery (installed KK + Gapps) ==> OK
BUT now every time my phone boots it is showing the yellow triangle.
My quesiton is : what can I do? Is it a real problem now after having managed to install a custom rom?
flashing anything from odin besides official stock roms, will increase your flash counter,
hence the yellow triangle. its normal but you could use Triangle Away by Chainfire in Original Android Development, to remove the yellow triangle
where do i get bootloader for kitkat 4.4.4?
