Something similar hapend to me yesterday, flashing older baseband. Twice and the both times it delited the cache partition and could do anything about it.

Even if I restore older copies using recovery there was no cache.

So I flashed the the latest firmware using flastool and then restore a copy I've made with v13 or v14 (cant remember) and now everything is fine.

Forget about flashing older basebands.

Doom, any plans on a new kernel for FW .58 users? Its got the newer baseband 58
[Xperia Arc Android Development] plopingo:
Same here Baseband 58 since I've flashed the last FW 4.0.2.A.0.58
[Xperia Arc Android Development] DooMLoRD:
WOW... that is a LOT...

i am sorry but i am not able to understand why only a few users are having such high battery drain... in my tests in 7 to 8 hrs with all settings as urs i have total 10-14% battery drain... 22% in 7-8 hrs is high...

hey guys i have already checked the kernel sources for .58 only one small change is there and that too related to voice (calling i think)...

please try my v15 kernel on that FW...
[Xperia Arc Android Development] rahul.pillai:
Okay, but can you expand on changes in terms of "Voice"?
[Xperia Arc Android Development] DooMLoRD:
here is the diff:

@Doom

For any reason I'm getting a forbidden message when trying to download v15 modules.

>.< This evening that I have time to install new kernel and reconfigure all...
[Xperia Arc Android Development] DooMLoRD:
damn it... seems the server went down again x-(

wait i will upload to mirror
[Xperia Arc Android Development] xexijreil:
Thanks a lot!!

Btw, I was going to try v15 with latest .58 FW and -56 baseband, also gonna install SE Tweaked v0.7, but I'm up to test any other FW if it's better for your development. Any suggestions?
[Xperia Arc Android Development] DooMLoRD:
done mirrors added please check main post...

kindly test on latest FW
[Xperia Arc Android Development] xexijreil:
Thanks! I meant -36 baseband, is it better that I leave it like it is the FW?

I know some users have had some issues cause of putting older basebands in newer firmware but maybe it's because of procedure. I remember a user named babygau saying this was the way he did it:

And he didn't report any issues with this. Should I try .58FW with -36 baseband??
[Xperia Arc Android Development] DooMLoRD:
just use newest flashtool to flash baseband only...
[Xperia Arc Android Development] plopingo:
Have 1 issue with the kernel on the last .58 rom , my phone restart randomly.

Otherwise all run fine, good battery improvement :)
[Xperia Arc Android Development] Ninolina:
I have a huge battery drain with v15.. can somebody give me the link to stock Kernel just to try if there is a problem with my phone or my phone just is not compatible with this Kernel.. My Battery usage shows that the biggest drain is from Screen and it is set to 20% brightness..:-( What to do?

Thanks in advance..:-)
[Xperia Arc Android Development] swavab:
Download .42 stock rom ftf file and extract with 7zip and flash the file inside kernal.sin with fastboot with command fastboot flash boot kernal.sin...to get stock kernal
[Xperia Arc Android Development] Ninolina:
Thank you both for answering..:-) I will try that.. It was different on my previous device HTC Desire... There were Kernels in flashable. zip files..:-)

Thanks again..:-)
[Xperia Arc Android Development] spida_singh:
Flashed the latest HK Global FTF (.58 FW) using latest Flashtool (latest 58 baseband)

Flash latest DoomKernal (V15) using latest Flashtool

Installed Acronium 2.1 ROM via recovary

Installed latest DoomKernal modules via recovary

Performed factory reset (wiped cache, data, sd-ext and android secure)

Wiped Dalvik cache

Fully charged today, in just over an hour, with some whatsapp usuage, facebook and text messages, it used 3% in one hour.

Which is well within my expectations. Can you guys try the latest aronium ROM frm sratch, its excellent on battery life.

No issues here :-D

I will report again at the end of the day.
[Xperia Arc Android Development] adamtan:
Just wondering if you are doing the same steps as me.

im looking to flash .58 also with DoomKernel from .283, without wiping user data.

So i flash .58 without wiping user data.

flash Doomkernel, and recover my previous backup

Zergrush it to root it

am i right in this manner?
[Xperia Arc Android Development] Flo95:
DooMKernel rootes the device, so you can skip the ZergRush thing to root it.

[Xperia Arc Android Development] iridaki:
Hello guys!

Some of you know me from the X10 forums, but anyway I bought an Arc S and I am loving it! :D

I immediately unlocked bootloader and flashed this kernel. I also downgraded baseband (to -36) as I gathered older basebands are gentler to battery life.

So far, I am amazed. Kernel seems almost too stable to be true! I overclocked, undervolted, played with governors, etc. DoomLord does know what he's doing!! ;)

I had a small issue though and a huge thanks again to DoomLord for his kind advice:

Sometimes apps could not gain superuser access and so they froze and/or FC. This was annoying, especially for startup apps that require root, such as SetCPU or Call Recorder.

So, as per Doom's instructions, I removed the busybox binary from /system/xbin (this was the version included in the kernel itself) and then downloaded Busybox Installer from the Market and installed the latest version. Rebooted into recovery, fixed permissions and the problem disappeared! :cool:

I hope this would be of some help for other people too.

Cheers!!
[Xperia Arc Android Development] iridaki:
I have been constantly using the phone for almost straight 9 hours (as it's my new toy!! :D) and I still have 12% decreasing fairly slow.

WiFi on a lot, data always on, autosync Google, FB, Foursquare, Tapatalk, taking pictures, browsing, browsing the Market... The list is endless, I've been stressing the phone to its limits! LOL!

Here is my graph:

I think it's pretty impressive, especially considering the phone is brand new, battery has only been discharged and recharged once.

I am on baseband 36 and the latest stock firmware 42.
[Xperia Arc Android Development] ShyamSasi:
I tried to flash baseband 36 but it's stuck at the initial bootscreen :( Not sure how to flash it. Extracted the ftf package for 386 and replace system.sin and repacked it and tried still same result.
[Xperia Arc Android Development] DooMLoRD:
iris u going to kill the phone arent u? ;)

just use the new Flashtool... it now has options to flash baseband only...
[Xperia Arc Android Development] iridaki:
You think? I think it's holding up really good!!! :)

So, it shut down after 11+ hours, with 7 hours screen on!

I think I can safely say that this kernel is not cause of abnormal battery drain.
[Xperia Arc Android Development] Duvel999:
THX. DooMLoRD :cool:,

V15 works perfect on HK Generic .58..

Glad I unlocked the BL...LOL

Recovery works good, missed it since X10i (Wolfbreak..:p)

Any advice for SetCPU governors ?
[Xperia Arc Android Development] Ninolina:
Can you, please, give me the link to the file which I have to flash so that I can downgrade baseband (to -36)? I have so big battery drain that I dont know what to do with my new phone... I also have ARC S, its just a few days old...:)

Thanks in advance...:) I really hope for help...:)
[Xperia Arc Android Development] Duvel999:
tried battery calibration of market?
[Xperia Arc Android Development] iridaki:
I downloaded the ftf package from this thread and then flashed

baseband ONLY

,

with the new FlashTool. Good luck! :)
[Xperia Arc Android Development] Ninolina:
Yes, I did... Its even worse after calibration...:( It use almost 5% of battery per hour in stand by mode (screen off)... I had HTC Desire and that device had a poor battery but this is much worse than Desire... I use the same apps and screen is on 20% brightness... I dont know what to do...:(

[Xperia Arc Android Development] Ninolina:
Thank you very much...:) I managed to change Baseband...:) It was not all easy since I did have some problems and had to flash several times but now it is 36 at last...:) So now I have Arconium 2.1 ROM with my girlish theme, Old Baseband, DooMKernel [Rel:v15][Dt:17/Nov][FW:4.0.2.A.0.42]....:) So I hope I will solve my battery drain problem...:) I will report how my device is working after downgrading Baseband...:)

Thanks again...:)
[Xperia Arc Android Development] NeoCream:
So is it possible to flash the -36 Baseband on the .58 firmware? Currently I have the -56 baseband and I hope to improve battery life with the -36 baseband. Is the -36 baseband the 'oldest' or 'best one' or can I even go further back and take the very first baseband that was shipped with the very first ROM?

How about MIUI? Can I flash there the -36 baseband or is it a prerequisit to have -56 baseband to get MIUI (BlendMIUI) running?
[Xperia Arc Android Development] Ninolina:
It is possible...:) Here is my screenshot...:)
[Xperia Arc Android Development] xexijreil:
Willing to hear about your experience with battery drain =) I installed doom's v15(with latest FW and baseband) three days ago and I've got like 15-16% drain during night(6-7hours) just with data 2g on.
[Xperia Arc Android Development] ShyamSasi:
With baseband 36 battery life has improved for me. Today morning it was 100% 2 hours of music. I have configured JuiceDefender so Wifi is on and off by schedule few e-mail and Facebook updates and now it 8:45PM and I have 74%
[Xperia Arc Android Development] Duvel999:
man o man .58 drain my Arc like a new born thirsty Vampire..:cool:

time for .36

http://xdaforums.com/showthread.php?t=1302802&page=20
[Xperia Arc Android Development] joecool1029:
Switched to -58 and seeing the best battery life I've ever seen on the phone, well over 20 hours with moderate usage, sync on, a crapload of background widgets and stuff.

I had heavy drain on -36, only two things I did were flash the system and baseband on .58, I left the user, and the doomkernel v15, after flashing those two I just reflashed the doomkernel modules.

For the system I did my usual cleanup which was removal of anything facebook related, copying various package updates into system and I'm running overclocked at 1.4ghz now. Doesn't seem to matter too much on what scheduler I use, I'm getting MUCH better battery life on -58.

EDIT: I have a LT15a, please state your model so we can see if this is model specific, sometimes the radios do not function the same between model, on Arc I know we can flash LT15i or LT15a baseband no issue but older SE devices 3G may not work, or mismatch in baseband firmware and radio libs on the phone cause excessive battery drain, this is the case for the X10 mini pro.
[Xperia Arc Android Development] Duvel999:
removed all the crap too.

What tweaks / updates etc. you use?

:cool:
[Xperia Arc Android Development] Ninolina:
Well, I must say that downgrading my Baseband to .36 didnt do any good to my battery...:( It still uses 5% per hour in stand by (screen off) I am now back to Baseband .56.. I see you are talking about some Baseband .58? Are you sure there is .58 and that you dont mean .56? If there really is .58, where can I found it?

Thanks in advance...:)

I flashed 36 baseband yesterday and ended up with memory corrupt this morning. Dont know how it was related. I cant install anything, I cant received any message. Switching back to 56 now. I have no battery issue in standby. Only during data usage.

Thank you for links, but I know about Firmware .58...:) My asking was about Baseband .58 as people here were mentioning Baseband .58... So I have this Firmware .58 and it use Baseband .56...:)

This LT15i_4.0.2.A.0.58 Generic Global Hong Kong(World) contains the .58 baseband.

[Xperia Arc Android Development] Flo95:
Since 4 days my Arc sometimes bootloops while charging or once while lying around. 2 times while charging and once while tethering.

But the guy I opened the hotspot for could still browse the web, so it doesn't really crash or WLOD like the X10 did.

It repeats the startup animation again and again, shows the lockscreen for a few seconds and then repeats the startup animation and that untill I do a battery pull.

Does someone know the reason for it?
[Xperia Arc Android Development] DooMLoRD:
Strange... What's ur current setup?
[Xperia Arc Android Development] Chewitt:
Just want to say Thanks DooMLoRD My Arc is a completely different device thanks to your Kernel, Great work you are doing here.
[Xperia Arc Android Development] spida_singh:
A bit more on battery

I can get 1.5 days usuage with it with light / normal usage at times. Excellent battery with latest baseband and .58 firmware.

This is with 1.2 OC, smartass V2 and noop, DK voltages applied :-D

This with Aroniums ROM and DoomKernal, can't breat it :D
[Xperia Arc Android Development] Crocodile1973:
anyone got the .58 baseband only. cannot download the ftf from the link in UK for some reason.
[Xperia Arc Android Development] tRippinthehead:
With the stock kernel the battery life is excellent. Using the SmartassV2 governor only and this is the only change. The problem still hidden somewhere in the custom kernel.

LT18i .42 firmware @ 56baseband.
[Xperia Arc Android Development] iridaki:
OK, it's off-topic, but I got to ask: is this for real?!??? :eek: Excellent indeed! :D

I get 4-5% drainage when screen off with DoomKernel and 1% or less with stock.

When screen on, usage seems to be the almost identical.

But I don't really mind, because of all the extra features. :)

And the fact that I do own a charger! :D
[Xperia Arc Android Development] megacrazy:
So any ideas on what's causing the battery drain? I've tried quite a few versions of this kernel and they all drain about 5% if the phone is not used. Stock is about 1% as many mentioned. I noticed that if I turn off the cell data connection drain slows to about 2% from 5%.

The positives clearly outweigh the negatives but it would be nice if the problem was solved. It would probably make more sense to solve existing issues before adding new features at all?
[Xperia Arc Android Development] DooMLoRD:
i had posted this a few days back....

anyways if i get time i will try making a clean merge of my modifications into .58 kernel sources to see if it helps with the increased battery drain issue..
[Xperia Arc Android Development] joecool1029:
Really, the -58 seems to fix the drain issue here most of the time, i still get some excessive drain once in awhile but it only lasts short bursts, not around the clock now. The -56 baseband was just crap.

This doesn't appear to have anything to do with the kernel.

hi, today i decided to unlock my BL...

and now i don't mean to sound noobish but is there a new version for .58 FW? or will .42 kernel work with .58?

Root is only working partially for me, busybox does not work right and the busybox app from the market says that remount does not work properly.
[Xperia Arc Android Development] babygau:
Stay calm, DoomLoRD is double checking his mess-up kernel and will be having a stable version very soon
[Xperia Arc Android Development] rafuru:
Same here, but with adb enter "su" and "busybox" and works..
[Xperia Arc Android Development] DooMLoRD:
There is no "mess-up kernel"... the only issue was that of cpu max freq getting set beyond bounds... and this can be resolved using setcpu/nofrills cpu app...

And in anycase, since SE have released new kernel sources overclock can now be implemented...

Which version of busybox worked properly from market?
[Xperia Arc Android Development] tRippinthehead:
Cool, looking forward to the new version for test :)
[Xperia Arc Android Development] ranblv:
The market version of busybox installer does not work, it says that remount is not working properly.

which installer did u use there are many available ;)
[Xperia Arc Android Development] babygau:
Just my kidding friend, btw, looking 4ward to ur new version
[Xperia Arc Android Development] DooMLoRD:
thats ok mate ;)

i am slightly bugged cause my main linux machine is acting up on me :(

darn thing is corrupting the ramdisks (i dont get whts the problem)
[Xperia Arc Android Development] jlmcr87:
Please Doomlord make and only rooted .img file
[Xperia Arc Android Development] DooMLoRD:
i am not following... why u dont want an additional featured (recovery, pre-rooted) boot.img?

the kernel is same as Stock SE... currently it isnt even overclocked..
[Xperia Arc Android Development] kistigun:
why not use the rooted boot.img?
[Xperia Arc Android Development] jlmcr87:
If its the same why the lag? I don´t want to install set cpu
[Xperia Arc Android Development] DooMLoRD:
hey mate:

for the time being u can use NoFrills CPU app (its free) to fix the incorrect cpu speeds (lag)...

it will be sorted once i implement the overclock kernel..

but if many users want a simple ONLY insecure kernel (that means not rooted by default/no recovery/no extras) then i can make that too...
[Xperia Arc Android Development] jlmcr87:
I know you are resolving it, i only want if you can explain me whats causing the lag, and why this lag if you say you are using the original kernel.

I don´t know about this things....but i want to ask you if maybe with an only rooted .img there will be no lag? This is why i´m asking for this all time. Thanks for your hard work! Sorry for my ignorance
[Xperia Arc Android Development] kiz1983:
izzit lag tht bad? i rooted mine using bin4ry script n does not hav tht lag u all mentioned..
[Xperia Arc Android Development] kistigun:
after flashing back the stock kernel i still have root(but no cwm). Is this normal?
[Xperia Arc Android Development] babygau:
I think it's ok, coz the superuser is on ur system partition, not on kernel partition, but i don't think it's working OK
[Xperia Arc Android Development] DooMLoRD:
ok i will explain why the "lag" is there... ok so the thing is i was using the OC compatible ramdisk on non-overclocked kernel... ;)

thats why that max was getting throlled way out of spec :D

so it was setting min freq to 245Mhz (which is ok) BUT the max freq was getting set to 1017Mhz (which on stock/non-overclocked kernel is not there :eek:)... so when the phone booted up the max freq was getting lowered to some ODD values as u can see here:

so that is wht was causing the "lag".. anyways since sources are now available (just posted by SE yesterday) i can now implement the overclock (which will have the 1017Mhz freq) and this problem will be resolved...

sorry guys for the small error

yes my kernel has the autoroot script i made which will copy su to /system (BUT busybox wont be copied as currently busybox is used from my boot.img).. i will add that soon...
[Xperia Arc Android Development] babygau:
So, when is the new kernel ready :)
[Xperia Arc Android Development] Crazypinoy9:
I'm not really sure if this has been talked about already because the search isn't pullin any results...but I just switched to the lt18a from the lt18i, flashed the lt18a with v15 and for some reason I have no more data. Wifi is working fine so assume i flashed the module correctly but can be wrong.

the kernel works ok on the "A" version right?
[Xperia Arc Android Development] DooMLoRD:
It shouldn't matter... It will work on both A & I versions...
[Xperia Arc Android Development] Crazypinoy9:
Thanks for the quick response!

That's what I figured. So I did a little bit of digging outside of XDA and found the correct access point settings for AT&T and now it's working again.

One more question that I do have is where are the LT18i/a firmwares? I flashed the LT15i_4.0.2.A.0.42_Generic Global and it seems to be working fine but now my phone says it's an LT15i...LOL! I've found the UK and Nordic firmware but not a global firmware that will work in the US...or can I flash the UK version and be ok?
[Xperia Arc Android Development] DooMLoRD:
they are the same mate... lt15/lt18 i/a the ROM and other stuff is same... only based on the CPU stepping the stock kernel will run either at 1Ghz (on ARC) or 1.4Ghz (on ARC S)
[Xperia Arc Android Development] Crazypinoy9:
Thanks for clearing that up for me!

I really appreciate the help!
