Can anyone help me installing this kernel in Linux Mint, or a generic procedure for Linux?

I bought an used Arc with Free Xperia Rom then I installed the ROM called "S.E. Tweaked" and now it's stuck post SE logo with black screen. Every ROM I try the phone can't complete boot.

Then I realized that I need this kernel, but I'm using Linux and don't know what to do. I'm getting crazy with this....fu** I can't even flash back to stock ROM... It's so difficult, with other devices the kernel update procedure is far more simple: put zip in SD card, flash kernel.
[Xperia Arc Android Development] Flo95:
Do you or one of your friends have a Windows pc?

If yes, flash the stock ROM with FlashTool to get it running and then flash the kernel.
[Xperia Arc Android Development] Duvel999:
use Flashtool 0.6.6.0.for linux, flash the kernel again then

you got the Bootloader unlocked?

try a windows pc from a friend

I got Macbuntu 10.10 here, but use a W7 laptop for this..
[Xperia Arc Android Development] GhostR1der:
Can you link me the stock firm and a guide to flashboot? I have little knowledge of Windows OS...

6016 as most are using that one. I don't get very good battery life, even worse than v15 so I want to use that one for a bit longer. I also reflashed the device so maybe it's now better. Overclocking and underclocking still much less stable than before on v15.
[Xperia Arc Android Development] Duvel999:
I use it on SE Tweaked 8.5 & several customizing etc., It's Really a big improvement compared to V15.

The Draining is over...

Ok, will do as soon I can get into fastboot mode ;)

My phone has stopped liking fastboot mode lately and blinks blue once when I insert the cable while holding the menu button and then just shows the doomkernel logo without entering fastboot. Works one time out of twenty maybe so it takes some time. Same thing happens when I choose to enter fastboot mode from the menu in recovery mode. It has worked before so it's a bit strange, anyone else heard of this?
[Xperia Arc Android Development] DooMLoRD:
take out battery for few minutes

then connect USB cable and keep MENU button pressed... now connect battery... device should enter fastboot mode directly
[Xperia Arc Android Development] frelle218:
Thanks a lot, it worked :)

I get same with test5.

with V15 there is no problem.

How to fix it ?
[Xperia Arc Android Development] DooMLoRD:
governors have not yet been optimized to use new cpu freq table...

that is why i have mentioned before that this test kernel should be used only with stock settings
[Xperia Arc Android Development] Flo95:
InteractiveX works fine for me, even if it isn't optimized.

Sometime ago I used smartass(V2), too. Bur interactiveX gives more performance :)

[Xperia Arc Android Development] iridaki:
Here are my results from testing test 6 kernel, on stock firmware .58, baseband -64 and appropriate libraries, kernel stock settings, no overclock or undervolt.

I managed to get 26 hours before the phone reached 5% but my battery graph was unusually steep. I see nothing odd in the BatteryStats though.

All in all, battery life is improved and the phone is reliable and stable.
[Xperia Arc Android Development] DooMLoRD:
hmmm

can u check with -36 baseband?
[Xperia Arc Android Development] St0rmer66:
No actual graphs/figures but I can DEFINITELY say that v16 #6016 is giving me a MUCH MUCH MUCH better battery life compared to on v15 on my Arc. Mostly the improvement is when the phone is idle, when the phone is "awake" then drain is approx the same as before (to be expected!). Added literally HOURS worth of battery back to the phone now per charge.

Have been overclocked to 1.4ghz with "On Demand" governor and no stability problems at all :cool:.

Thanks so much DoomLord! :D. I loved using your kernel even with the bad battery life, now it's close to perfect :).

Here's my final for #6016.

Doom, I did two things that improved a lot: disabled the CallRecorder in the preferences options of the app (it's better to activate it just when needed), and removed the Fast Dormancy (even though it still shows wakeups in the Battery Stats but it's like it didn't drain any battery at all!). I forgot to dump the stats to file but you at least the screen will help for something. Just AWESOME results :)

sd-ext partition not mounted (DoomKernel)

On the attached screeenshot you can see the identity of my phone:

XperiaArc with Doomlord Kernel and V6 Supercharger script running.

My problem is that although I have partitioned my sd 8 Gb card, the ext3 partition cannot be mounted. I failed mount it using either CWM Recovery or Link2sd.

I moved my applications to sd card manually, but I suppose that having a functioning ext3 partition could more efficiently decrease the application storage size of the internal memory.

I desperately look for the solution of the problem. I searched a lot of threads but it was impossible.

How did you create your extended partition?

using minitool partition.

The partition has to be primary and no label name. Have you tried that
[Xperia Arc Android Development] iridaki:
Testing V16 test 6 kernel, on baseband -36, haven't turned on WiFi at all.

It's been a busy day so I didn't use the phone much, just lots of calls and data on.

[Xperia Arc Android Development] nigeta_gr:
Problem solved thanks to harfot and irid@k!

Thanx, harfot and irid@k! !

Finally, it was like a plane crash:

There were more reasons than one to create this problem.

I had to uninstall Swapper 2 from my Arc, to erase existed swap partition on my sd-card, to format ext partition as ext2 and not to use a label name.

Applying all these, I finally saw my ext partition mounted.

Now i am looking for a way to merge swap and ext2 partitions (as I don't have minitool pro), but it is not crucial.

I suppose that I'll leave the 256 Mbs of the old swap partition unallocated.

No more experiments!

Thanx, again. I'm greatful!

well then #6016 + -36 baseband seems to be a winner then :)

what do u guys think?

well currently since the main battery draining issue has been resolved i am concentrating dev work on other devices i have...

in anycase i will shift the modular based kernel to a later date, too much work needs to be done on the related aspects (app, recovery menu based selection, etc)...

the next kernel release will have 0% battery fix/patch integrated!!! we have tested and the 0% battery fix/patch doesnt affect normal working of users who dont have that issue... so from next kernel onwards even those users can now use my kernel :)

THANK YOU ALL FOR HELPING OUT WITH TESTING!

it is clear to me that #6016 is the best option and is giving incredible results coupled with baseband -36 and undervolting... so the future kernels will be based on these #6016 changes...

DooMKernel v17 released!!!!

DooMKernel v17 released!

firstly thanks to everyone who helped with testing v16 test kernels! it is from this feedback, which was posted by many users in this thread and even via p.m., that we were able to figure out the best combination which will give better battery life and great performance!

[ tips / recommendations ]

for optimal results it is HIGHLY recommended to use -36 baseband with corresponding libs... the baseband files and libs can be found here:

http://xdaforums.com/showthread.php?t=1382657

(thank you Iris!)

for better battery life try undervolting... start off in steps of -25mV and see which is stable for u... for my ARC -100mV was stable...

before u report any battery drain issues please read this:

[GUIDE] HOW-TO Properly Evaluate Battery Life and Provide Useful Reports

[ features ]

changes in cpufreq driver & cpu freq table - acpuclock-7x30 from fw 3.0 + removed pll2_fixup + acputable based on 19.2Mhz as base clock

disabled NFS/CIFS - this was causing increased battery drain in new kernel sources

incorporated "Workaround to 0% battery issue" (modified battery driver) - thanks to Bazoocaze, this does not affect normal users, users who face this 0% battery issue should check the above thread for corresponding app/script]

incorporated small fix so that on ARC S the device will boot at 1.4Ghz as bootup max speed - the kernel (ramdisk script) will search for ro.product.model in build.prop... if it sees LT18 then 1.4Ghz will be set as bootup max speed else if it sees LT15 then the bootup max speed will be 1.0Ghz

tuned all governors to new cpufreq table - not sure if this works correctly please test with ur fav governor

the battery drain will be slightly higher when WIFI is active, i am investigating this...

download links at first post!!!

enjoy!
[Xperia Arc Android Development] Flo95:

No flashing problems with v17 - only problem was me forgetting to wipe dalvik casche so that brought me back on baseband 64, but then I start testing there.

Overclocked to 249Mz~1.4GHz,

- rebooting at once with smartassV2 and noop.

With this kernel I have to wipe cashes to get phone connection after reboot.

I will now test the kernel the next 24 hours at 249Mz~1.4GHz and with ondemand and deadline without undervolting.
