I didn't find in the changelog that in the version k3-30, the emmc bug was disabled. But Was the bug actually disabled in k3-30. I am currently running on CM10. So now if i flash XWLPO - 4.0.4 firmware from samsung (which has the emmc bug) via ODIN. And after that, I flash Speedmod k3-30 via ODIN. Now is my phone safe? Can i do normal things like wipe data/factory reset in recovery, nandroid backup/ restore in recovery, install another rom from recovery? Can anyone confirm that i will be safe so that i can flash now. My phone is so valuable for me so that i can't do any wrong things :). Thanks in advance :D
[Galaxy S II Original Android Development] iNeri:
You're safe with this kernel:

I guess you did not read the change info did you ?

Not for 4.0.3

anyway... sensors work.

dialpad key code *#0*# brings up the hardware test screen... the gyro graph is very stable ... compass very stable.... light sensors function fine... auto rotate fine... all good here.

I am on 4.0.4 ROM (XWLPO)

CWM 5.8.1.8 issue

Hello,

I using this kernel just because it comes with the latest WanamLite 12.3 rom. I think that the CWM 5.8.1.8 has a bug. It seems to me that the menu items for Internal and external SD cards are exchanged. When I choose install zip from SD card, then I was pointed to internal SD card, and when I choose install from internal SD card, then I was pointed to the external SD card. Can anybody check that. I reinstalled that rom several times with full wipe, etc. but still the same behavior.
[Galaxy S II Original Android Development] ducutu:
Yes, that bug is an old one, in CF-Root CWM is fixed
[Galaxy S II Original Android Development] danielo:
Can you tell me how can I change CWM to proper one without changing the kernel, please?
[Galaxy S II Original Android Development] fenomeno83:
Problem is in 500mhz freq...don't use under 925mv in ics...
[Galaxy S II Original Android Development] Qwerty__-:
after 1 days of use, i see some app which need grant root acces like luckypatcher doesn't work, he says me i'm not root, but i'm...

same case for Droidsheep...

any idea ?

btw thx for this kernel ;)
[Galaxy S II Original Android Development] VAXXi:
Also, another bug (I know everyone hates these, but ...): on a stock kernel, adb push to external_sd works as normal. On K3-3 it fails with "permission denied", even with adb started as root and the external SD card mounted as r/w.

adb push to /sdcard/ works, but when trying to move the file in the shell:

shell@android:/sdcard # pwd
/sdcard
shell@android:/sdcard # mv test.file external_sd/
failed on 'test.file' - Cross-device link
255|shell@android:/sdcard #

No changes done to ROMs between tests, of course; just the kernel changes.

The mounted devices are of course different:

/dev/block/vold/259:3 /mnt/sdcard vfat rw,dirsync,nosuid,nodev,noexec,noatime,nodiratime,uid=1000,gid=1015,fmask=0002,dmask=0002,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0

/dev/block/vold/179:25 /mnt/sdcard/external_sd vfat rw,dirsync,nosuid,nodev,noexec,noatime,nodiratime,uid=1000,gid=1023,fmask=0002,dmask=0002,allow_utime=0020,codepage=cp437,iocharset=iso8859-1,shortname=mixed,utf8,errors=remount-ro 0 0

This is my battery using speed mod kernel k3-3......great actually this is my first time i get 4 hours.....thank you hardcore.....
[Galaxy S II Original Android Development] LNJ:
K3-3 works great on LPS.
[Galaxy S II Original Android Development] eric-filth:
Hardcore really good work. Before running two days with your kernel want say somethings.

- Always smooth and not only some parts. Is amazing what you did. All tasks here was smooth. Enter, exit app, minimize, maximize, screen transitions all perfect.

- very good performace with benchmarks and games

- good battery life about 1hour screen on + 3g i lost 20%

- and works perfectly here undervolt using tegrak ultimate.

200 - 1.200 (825, 925, 950, 1075, 1150) same uv using gb with except 500mhz

Congratulations.
[Galaxy S II Original Android Development] hirak99:
Though I have been using these for only a short time, let me take a shot.

In general Siyah offers you more control over the features, and has added undervolting/overclocking support. If you use Siyah, you must download ExTweaks, the complementary application, from market, which exposes all the settings. Search extweaks on xda to learn more about the settings.

Speedmod on the other hand comes with carefully tweaked optimal settings to strike a good balance between battery & performance.

Both support CIFS, high speed USB charging, etc.

Both kernels are undergoing rapid development with onset of ICS -

Problems to fix in Siyah's rc1 -

1. Wifi breaks for some ROMs

2. External_sd inaccessible for some ROMs

3. Data usage limits are not accessible (for anyone who tried)

4. Frequent reboots, probably associated with those who use undervolting

Though development on Speedmod started late, I daresay the wait has paid with a stable enough kernel to begin with. Nonetheless following problems have been reported -

1. Cannot push to external_sd through adb (I can confirm, but you can ignore if you don't know what it means)

2. Problem with some apps loosing root reported - though it may have been fixed by updating the superuser from market

As to which one is better, it's your choise :) If you like tweaking numerous settings to your content, or need under/overclocking, Siyah is for you. If you want a pre-optimized kernel which eats less battery and yet provides great performance, Speedmod it is.
[Galaxy S II Original Android Development] pikachu01:
The root problem is caused by SuperSU. Just select "Switch to other Superuser app" in SuperSU and install Superuser and you're good to go :)
[Galaxy S II Original Android Development] hirak99:
That's great will remember the option for future : )

I like superuser more than SuperSU myself, and may be I didn't notice it because I am already on superuser. SuperSU somehow tended to forget rooted apps everytime I used the later versions of CFRoot, whereas with Superuser it's a breeze.
[Galaxy S II Original Android Development] akbarhash:
Hi hardcore thanks for the kernel, It is working well.

One small request though, the superuser app that comes with the kernel is an old version and not optimized for ICS. It is not a big deal just have to update from market but the thing didn't show up in updates automatically had to manually update.

So my request is can you use the newer superuser app (It has been updated since Nov) in the next version just to make the experience easier for new users.
[Galaxy S II Original Android Development] planetf1:
Thanks for building this kernel. I loved the GB ones!

I ran speedmod briefly over the weekend - after experimenting with siyah and plain cf-root (neak seems to have some challenges).

I'm still finding the LED brightness levels in auto on the over bright side. I'm running LPS now. I know you felt the display was no longer oversaturated so modification wasn't needed. For me it does feel over bright - just wondered if this is an area you may relook at in future?

Also do we know how close the released kernel sources that speedmod (and the other kernels) are based on is to the current kernel being used by samsung is LPS etc?

Thanks
[Galaxy S II Original Android Development] monster75:
Thank You. I'll try with next ICS ROM. Now I'm back to GB and everything works great :)

---------- Post added at 10:11 AM ---------- Previous post was at 10:04 AM ----------

Why should hardware stability depend on OS? Why with GB it's stable and with ICS no? I'm thinking about some optimizations that ICS doesn't have yet...
[Galaxy S II Original Android Development] Qwerty__-:
Always done and nothing appends :/
[Galaxy S II Original Android Development] sayem_unlimited:
Thanks for your work Hardcore. Enjoyed SpeedMod Kernel K2 release on GB.

Now i'm running on CriskeloServanTeam V05 -ICS 4.0.3 (Firm Official XXLPQ) rom. Can i install Speedmod K3 on top of it? Please forgive for such noob question.

Please reply.

Thanks.
[Galaxy S II Original Android Development] hardcore:
Thanks, that's how I would describe ICS in general - it is really smooth. And once optimized with Speedmod it is really unbelievably smooth. I really like it. Can't wait for Samsung to release ICS for the Galaxy Note.
[Galaxy S II Original Android Development] hardcore:
I don't see why not, as long as it is a Samsung-based ROM.
[Galaxy S II Original Android Development] ducutu:
Just get used with that. Don't play with CWM in brick bug times .... :D

After all how often do you play with CWM? Enjoy your phone !

[Galaxy S II Original Android Development] ata1918:
Rebuild your kernel with the newest sources. Make sure to disable mmc cap erase.

Cheers
[Galaxy S II Original Android Development] Gammelgustav:
?

SpeedMod is based on update4 sources right?

But there is a 4.0.4 Camera fix - (in the Patch files I think), but where to find in the patch file K3-30
[Galaxy S II Original Android Development] hakaz:
SpeedMod K3-30 depends on Update7 and the camera fix is a value change of CONFIG_VIDEO_SAMSUNG_MEMSIZE_FIMD=12000 to CONFIG_VIDEO_SAMSUNG_MEMSIZE_FIMD=9000 in the source (it's mentioned somewhere around here in the thread). But CONFIG_VIDEO_SAMSUNG_MEMSIZE_FIMD is set in various source files, I dunno if they changed all occurences or in u1camera_defconfig only. Cheers :)
[Galaxy S II Original Android Development] Gammelgustav:
Ok thx will look it up ;)

[Galaxy S II Original Android Development] cammel:
Sorry to ask this again, I know that everyone will answer me that this kernel doesn't have the emmc brick bug enabled, but I couldn't find anywhere on the first post or any answer from Hardcore itself telling that it is disabled. I really would like Hardcore himself to say that it is disabled and that we are safe performing wipe actions on cwm with this kernel on 4.0.4 Sammy roms with the faulty chip.

Sorry if this sounds bad, it is not my intention at all, so please don't kill me, I'm just trying to say this with all the respect I can to Hardcore and to all of you guys, so please don't take it the wrong way... Please...

[Galaxy S II Original Android Development] ciprianruse88:
how is the charging speed?
[Galaxy S II Original Android Development] SaneinOne:
Charging speed would seem to be back to status quo. That being said, I did experience an issue while charging decide this afternoon. Rooted LQB using latest SpeedMod. Device charging froze at 3% and extremely hot. Pulled battery and reboot resolved issue.
[Galaxy S II Original Android Development] kotaxor:
Yup, after a day of use, the usb charging speed has increase to 2x that of version 30 and it's not that hot during charge.
[Galaxy S II Original Android Development] hardcore:
The charging driver has not been modified between versions. It is quite advanced and takes into account battery conditions and temperature.

Maybe this is a sign of battery wear and tear.

I tried using 4.0.4. however I had a hard time modding the mms apk to have aosp mms with 2 avatar on sammy roms. I tried using aokp and cm but have issues on overheating and media scan and beside no FM radio.

Thanks anyway
[Galaxy S II Original Android Development] kotaxor:
Lol...think I need to get an extended battery.

But why would version 31 charging and temperature better than 30? It should be the same if its due to wear and tear or worse.

Or maybe I did not have sufficient time to test 30 thoroughly as I have just upgrade my rom 3 days ago.

Could it be due to the rom or the modem usage?

As GB seem better in charging and temperature.

And in my previous rom 4.0.3, version 20 charging and temperature is so much better than 25 or 26.:confused:

It's not a bug ... SpeedMod is not 100% compatible with CWM Manager app (and never was).

But CWM recovery (mode) works fine. You can do everything after booting into recovery mode.

Sorry, that's nonsense. The kernel cleaning script should remove traces left over from kernels. When you run it after after installing Speedmod it may remove necessary files (when there is anything Speedmod related in this script, don't know).

My observation was on clean install stock wanam XWLPT then 3-31, after full wipe, reduced heating while surfing and playing games, also i checked phone while charging, it was cool.. no exessive heat.. battery consumption ok, 2 days testing, no problems or FC or reboots...

Note: On previous install - NO WIPE, over other rom (XWLPT wanam modded), experienced force closes and reboots, and some slowdowns (dont remove or freezze stock touchwizz).. baseband dissapear, i did 2 times no wipe install to fix all but no success - after full wipe all ok...

All wipe recommended for xwlpt install... (and in my case - dont touch stock touchwizz / apps that I have removed: all hubs, all SNS, all readers, news etc. mobile tracker, samsung acc, software update)
