That's really weird, how do we figure out, whether we are on ics bootloader or not, any hints anybody?

Sorry if this is an stupid question!

Swyped from my GT-I9100 using XDA App.
[Galaxy S II Original Android Development] It_ler:
Look into settings menu => phone info => status/state => serial number.

If there is "unknown", you are not on ICS bootloader.

If there is a sequence of numbers and characters, you are on ICS bootloader.
[Galaxy S II Original Android Development] Karpfenhai:
So, yay, im still on GB bootloader... But i don't have this issue, my phone is booting flawless every single time...

Btw, how do i update my bootloader without loosing data?

Sorry if this is too off topic.

hi mate

here you can find ics bootloader http://skywanker.net/download/download.aspx?link=GT-9100/bootloader/GT-I9100_ICS_BOOTLOADER.7z

you have to flash with odin

Thanks.

No. Mobile odin does not flash bootloaders.
[Galaxy S II Original Android Development] zool84:
if you can flash bootloader / PDA through it, yes
[Galaxy S II Original Android Development] It_ler:
Just to confirm:

1. The bootloaders from Intratech's thread and skywanker.net are all unlocked/open.

2. Use PC version of Odin to flash the bootloader via Bootloader or PDA section of Odin.

3. This will be no wipe.

4. Mobile Odin does not flash bootloader and pit files.

Hope everything is clear now.
[Galaxy S II Original Android Development] zool84:
i never used mobile odin that's why i answered " if " :)
[Galaxy S II Original Android Development] Karpfenhai:
Thank you all guys, now i know the reason why I'm still on GB bootloader :-) I flashed my first ICS ROM with mob Odin...

Maybe this is also the reason why I'm not having the reboot issue?

One last question, do i have any benefit using ICS bootloader?

[Galaxy S II Original Android Development] zool84:
i noticed that with ics bootloader my phone start and shutdown are faster than with gb bootloader

if you want to reset the binary counter with a jig just flash old gb bootloader then flash back ics bootloader

cheers
[Galaxy S II Original Android Development] Agent_Adodas:
No need to Flash old GB bootloader, you can use Triangle Away to do this (works only on ICS).
[Galaxy S II Original Android Development] It_ler:
Ask the other way round:

Is there any advantage of staying on the old GB bootloader?

If you use TriangleAway app to remove the yellow triangle and reset the counter, you do not need a Jig any more.

And that was my only reason for using the old GB bootloader.

As Intratech provides old GB, new GB and new ICS bootloader, feel free to flash and use the one you want.
[Galaxy S II Original Android Development] Brotuck:

K3-17:

- Reverted some compiler flags to fix the problem of sometimes hanging at boot logo
[Galaxy S II Original Android Development] hardcore:
Guys, do try this and let me know if it fixes that problem. I suspect it could be due to a timing issue caused by one of the newer compiler flags.
[Galaxy S II Original Android Development] Roz3buD:
First reboot from recovery after flashing K3.17 : stuck on boot logo... A simple reboot solves the problem.

FYI, i wiped cache/dalvik before flshing the new kernel.

Just flashed some hours ago K3-17.

First boot : freeze at samsung logo.

1 boot each 3 (approx) : freeze at samsung logo.

For me it's same as K3-16 when before flashing ICS bootloader, then I prefer to revert back to it ;)

Hi there everyone..

Does anyone have problem with the wifi? I switched to speedmod k3-17 and I'm not able to on wifi at all... Switched to k3-16, same problem as well...

I've used the latest ultimate cleaning script 2.6.4 before flashing speedmod as well, cleaned cache and dalvik cache and still no change, wifi still cannot even be on... I've sinced restored back to my original kernal though but i would still prefer speedmod... Is there any fix for this?

I've flashed k-18 via CWM on XWLP8 (new Bootloader) now. No problem while booting. Also another reboot worked fine.

PS: also no WiFi-problem.
[Galaxy S II Original Android Development] pikachu01:
The wifi issue can be fixed by updating the drivers in which gokhanmoral has. I think that would resolve the min_free_kbytes problem causing boot hangs.

Anyway to have recovery use external sd as default for backups and restores?

Reason is in the event of a hardware failure the backups by default are saved and performed on external sd which is removable
[Galaxy S II Original Android Development] dee163:
Hey Hardcore,

Is it possible to include lower auto brightness values in your next release.

The default auto brightness for kernel K3-2 is too bright.

You can use titanium backup.

hi guys, which one of the downloads should I use for this kernel 3.0.15-i9100XWLP7-CL340913 etc? should I root the phone first? thanks!!
[Galaxy S II Original Android Development] It_ler:
Try the latest SpeedMod kernel version => K3-18.

Should work fine.

No, you do not need to root your phone first, if you flash SpeedMod by using Odin.

SpeedMod will auto-root your phone by/after flashing.

Use TriangleAway app from Chainfire to remove the yellow triangle and reset the counter.

Good luck !
[Galaxy S II Original Android Development] defenderko:
so,by flashing this kernel phone will be rooted and it will have cwm installed as well?can I expect better battery life? thanks
[Galaxy S II Original Android Development] It_ler:
Rooted: Yes, CWM: yes and batterylife: maybe ;-)

Have a look at my latest kernel test results => http://xdaforums.com/showpost.php?p=26088502&postcount=35

So, on my phone, nearly every SpeedMod kernel version has better battery life (in mixed usage) than stock XWLP7.

Could be the same on your phone, but could also be different on your phone.

Test yourself.

Results for SpeedMod / Phenomenal / Siyah / N.E.A.K. / Dorimanx / stock kernels

Everything is specific to my phone, my "normal" usage and my home location. Most values are exact results, but some are rounded. I usually have wifi, synch (three email accounts, calendar and news), Google Talk and Skype on.

For all custom kernels, I was running on ICS XWLP8 „Frankenstein“ ROM.

For stock kernels, I was running on the corresponding stock ROM.

Always using the Samsung's standard / stock 1650mAh battery.

For all kernels, I have changed nothing - just default settings.

I flashed SpeedMod K3-17 and added its results.

Here are my current results:

Benchmarks

Battery stats

SpeedMod K3-17 is very stable, very smooth and has nearly the same battery life as K3-16 on my phone.

Seems to be only a minor change to fix the stuck-at-bootlogo issue for some users only.

had a boot hang this morning with k-19 stuck on second boot screen, so rebooted, stuck on first boot screen, went into recovery cleared dalvik and cache, rebooted stuck on first boot screen.

rebooted into recovery, used kernel cleaning script, and reflashed 19, stuck on initial boot screen.

Then flashed 16 and left it, stopped at initial boot screen for a while before jumping into life . . but seemed to hang after android updating dialogue .. . so rebooted and it went through ok.

Flashed 19, again, without clearing anything . . and rebooted fine.
