Hi Everyone,
I am currently seeing unacceptable battery drain on my GT-P7500 (original SGT 10.1).
Battery capacity falls at 1.4% per hour overnight when the device should be in deep sleep. The problem seems to have started when I updated to ICS. Using BBS and other apps, I have established that the KWL l2_hsic prevents my tab from sleeping when mobile data is off. When data is on, other KWLs, notably, multipdp, secril_fd-interface and PowerManagerService, take over. My tab is not rooted.
I have been trying to sort this out for a few weeks but I'm no nearer to resolving the problem. The support from Samsung UK has been extremely disappointing (I'm being polite!).
Can anyone help?

I'm still happy with it. Tab lasts with normal use 4-5 days. Not using it, 1% per day instead of 1% per hour.
Also tried samsung portugal that had no idea about the problem. They told me to do a factory reset....

Hi Phibs,
Thanks for the feedback.
Unfortunately, the link you have provided takes me to a 404 error.
In view of the excellent battery life that you get, I am very keen to see what the link has to say.

Sorry!!!
Here goes
At last.
For those who have the drain problem and don't want to install a deodexed zipaligned and already rooted rom here goes what i did,
1 - Install stock rom from your country using odin.
2 - Install bootloader CWM. (I used CWM 6).
3 - Root your device using superuser or supersu. (I was not able to install supersu directly from zip file!!!???)
4 - Extract boot.img from CHN rom that you can find in sammobile.
5 - "Tar it"
6 - Install boot.tar via odin. Now you won't have wifi.
7 - Copy the following files from CHN stock rom. To copy this files you have obviously to extact them. You may use, I think Toldo won't be mad, his stock rom's Zipaligned, deodexed.....
/system/lib/modules/dhd.ko
/system/lib/modules/scsi_wait_scan.ko
/system/lib/modules/tcrypt.ko
/system/bin/wlandutservice
/system/bin/wpa_supplicant
Voilá. The P7500 finally deep sleeps for long long time.
Heuuu, not completely.
Yesterday, after several days working perfectly i found out that when you unmount a pen directly through the notification bar, the device stops "deep sleeping". A reboot will solve the problem. I already knew about this problem and the solution to prevent a reboot is to unmount the pen via settings.....
Hope this helps someone.
Thanks to Stiffmeister from another forum who used and cooked Toldo's Stock Rom (which are stock rom zipaligned, deodexed and unsecured) and solved the Draining problem.
Thanks to Toldo for his great job of extracting stock Rom's and making them available.

Hi! I'm in same case, but my battery drain about 2%/hour.
CHN Stock ROM is Chinese? I use to flash CM10.1, can I repair the error with this ROM?
In my case Samsung Spain says that it works perfectly...

Whitch version of odin are you using? Never had that problem.
I used version 3.07, choose the file boot.tar via PDA button.
If it doesn't work try to put inside the TAR boot.img and cache.img, both from the chinese ROM.
In reply to your previous questions, CHN is chinese.
Never tried CM10.1 since it still has minor bugs.

Thanks for your reply! Yes, I use Odin 3.07 like in snapshot. It stops in this screen, tab has the progress bar without evolution...
First i would try if battery drian stops with this method, then i try with CM10.1.

So, you first installed your original stock rom xwlp5. Wiped all caches. Then tried to install the kernel from chinese stock Rom, "taring" boot.img and cache.img.
Nothing happens and the odin freezes!?
Try once more to delete all caches and wipe dalvik cache. Currently the bootloader is the original one from samsung or it's the cwm?
Try to change the bootloader.
Is your tab a P7500 locked or unlocked. (ex. Vodafone......). Mine is unlocked.
I yhink the tar file isn't tared correctly, how do yo do?

I used linux.
$ tar -H ustar -c boot.img > boot.tar

Hi folks,
Although I started this thread, I am going to quietly back out and thank people for their replies. I do not want to root my tab as it is well within the warranty period. Besides which, I don't think it should be necessary. It's letting Samsung off the hook.
I am closely following the l2_hsic thread on these forums as the problem I am seeing seems to be caused by that wakelock.
AD
I had my Tab rooted and I tried all programs to delete extra wakelocks and it doesn't be totally effective, tomorrow will send the Tab to Samsung for second time, i hope they change anything to correct the drain.
I will post in few days!
I've loaded older version of modem (XXKK2 - Honeycomb) and I have no more ls_hsic problems! I'm on CM 10.1 (android 4.2.2). Kernel from CM 3.1.10. The modem got from this post:
http://forum.xda-developers.com/showthread.php?t=1867147
Try it!
I flashed the XXKK2 modem and that didn't help with the l2_hsic battery drain...
What did help was putting in a cheap pre-paid simcard and enabling the 2G dataconnection. I don't have the simcard topped up, it does receive a signal though, but bye bye l2_hsic wakelock!!!
I flashed HC modem and, at the moment, all is working perfect!! I'm not sure yet that problem is solvented but for the moment it's working...
Thanks!

You got an i9100 modem on your device from something you flashed (probably the theme package from the i9100 forums - but I didn't d/l it to look) as evidenced by your baseband reporting i9100XXLPH.
Though I think some of the packages you have tried flashing to fix it have modems, I would go to the appropriate modems thread (I think they are linked from the sticky in general) and grab whichever i777 modem you were running before and flash that...

ICScrewD should have given you the UCKH7 modem. Not sure why it didn't overwrite your i9100 modem. As I haven't been in this situation to have to get out of it, there may be more to it. My first step would be trying to flash just the correct modem package over what you currently have...other than that, others have been in this situation - search is your friend.

Ok I was still on ICSrewd when I tried flashing UCKH7 but it didnt overwrite the i9100 modem even after multiple flashes. I tried doing it thru ODIN and it still failed. So I went back to the Stock ROM and re-tried it and guess what....success!! ......which is weird, I'm not sure if it is an issue with ICSrewd new version 2.0.1...anyhow...now I'm experiencing ridiculous battery drain, so should I try various modem combinations to see which one works?

After all that flashing, you'll probably see heavy battery drain for a few days. I usually have to go 3 battery cycles full to empty (which is 3 days for me) before I see stable battery behavior after flashing new roms.

I should've read this earlier
What I did instead was flash the turkbey ROM and went thru 2 cycles with it already so now I'm seeing some level of stability i.e. 19 hrs of battery time approx with about 5 hrs of Screen On time, which is pretty decent I guess.
Thanks for advice mate.
Hi there
So i tried to install Steve's Kernel, but my device is in Boot loop now... (my device is international, it has Physical home button....)
i did some search around and found this : http://forum.xda-developers.com/showthread.php?t=1531850
but i am not sure if this is the solution to my problem...
i can go to recovery mode and download mode by the way
so i am gonna assume i am not completely ruined....
Any ideas guys?
porkho biv9
after my first flash I was in the same situation as you. flashing the stock rom was the only solution.
But in my case it was no problem, because I had nothing important on the device. It was almost fresh out the box.
I've the experience, that doing a full wipe causes a higher possibility of getting bootloops. So I only clear the dalvik cache after flashing roms/kernels. If it boots -->everything is fine.
Do you have a backup? CWM or titanium backup?
Hi
Unfortunately i don't have any of those....
do you think that link i gave in the 1st post can be useful?
Thanks in advance....
Yes, I downloaded the .pit and .tar.md5 file and did everthing of these steps:
Flashing Time
1.3: If your device is bricked and you can go to download mode:
1.3.1: Download one of the roms (according to your device)
1.3.2: Open odin, take the .pit file and put the rom .tar.md5 in the PDA SECTION
1.3.3: Before flashing, ensure re-partition is checked.
1.3.4: Flash, when the flash is finished your device should reboot.
1.3.5: When you device reboots, you will be in recovery with red errors which are saying mostly of the time: Can't mount... To erase these errors, WIPE DATA.
1.3.6 Reboot and enjoy your restored device!

I had no backup too and tried everything. This (zaclimon's thread) was my last hope after 2 hours of searching and it worked.
Hey !
ah, did i read that right? Re-partition HAS TO BE CHECKED??
and do you recommend installing Steve's Kernel after i hopefully returned my device?
yes it has to be checked in this case.
I had terrasilent 1.1 and klassik rom for 2 days but I had a lot of freezes, so I flashed the stock rom 2.3.6 and steve's kernel because the main reason I wanted the SGP4.0 was the combination of wolfson DAC+wolfson+poweramp.
If you are happy with music only, than this is enough.
But now I'm using my device more often (GTA 3 is on sale right now) and flashed terrasilent v1.2 two days ago. Now I'm waiting for the next version of StratusROM and will give it a try. Because sometimes I am not completely satisfied with the performance (sometimes) and it often wakes up while deep sleep causing more battery drain than usual.

Hi there
you guys mind giving me link to that Transilblaba thing ?
Thanks in advance...
Hi,
I have been using variiety of ROMs from 2 years on S2 i9100. Problem started with MIUI. Sleep of Death that used to be cured only with reboots. Then i changed the Kernel to "speedmod-kernel-s2-jb-k5-7-CWM.zip " and problem began.
I started getting Status 7 errors when i tried to update MIUI to newer version. I deleted asserts from Updater-Script and installed new version. Also, changed kernel to "Siyah-s2-v6.0b5-CWM".
But today, i opened MyTracks app and phone rebooted.
Since then, i would restart my phone. The phone will reach the "Media Scanning" stage and would then shut down (not SOD).
I restored my NANDROID backup but phone again shut down just after booting up --- right when "Media Scanning" icon appeared at top.
STRANGER -- when i tried to reboot phone after disconnecting phone won't start --- and doesn't go in recovery.
BUT when is being charged using charger phone is able to get into recovery.. and is able to reach and then shutdown at Media Scanning stage.
I made a mistake of flashing Official Firmware (from Sammobile) using ODIN from PC. Now, i do not have CWM recovery.
My phone behaving same even after flashing :-
1. Two different ROMs (Jellybam 7.8 and MIUI 3.7.5
2. Two different Kernels (Siyah-s2-v6.0b5-CWM and speedmod-kernel-s2-jb-k5-7-CWM)
3. Official Firmware Jellybean 4.1.2 using ODIN.
Now,
1. i can't go into recovery without charger
2. phone won't reboot normally without charger
3. shutsdown at media scanner, when rebooted after connecting charger
4. no NANDROID backup working -- same problem as above
5. Kernel changing did not help
6. Flashing ROM did not help --- MOSTLY switches off during installation process
7. ODIN-Flashing-Official Firmware has made me stuck with official-recovery (going to try deleting the asserts statement to see if installation succeeds without status7error)
Need expert help. Can anybody please help me out.
I won't mind paying for your efforts, too.
Please help.
Thanks.

However, the battery is charged 100% and i am able to enter StockRecovery and browse. It fails only during installation of ROMs / Recoveries/ Kernels.
Run rom nuke and kernel nuke scripts from hawerkpaul then reflash rom+gapps see if that does it. So cwm works ok? with out charger connection? If so try the nuke scripts. Also try super wipe by biftor.
Edit your on stock recovery now or cwm? Dont run scripts in stock get cwm bk on ohone then flash nuke scripts. Or redownload stock firmware and reflash with odin. Then flash philz kernel that will bring bk cwm.
Solved
Hi Friends!
It was a battery problem.
:crying: sad i wiped my emmc before checking battery.
Thanks for support guys.
Nuke Scripts are new for me. Shall explore that area, might be helpful in future.
Thanks again.
Rom Nuke scripts will clean up your system ready for flash. Same as kernel Nuke scripts. I don't use them much. I format system,data,cache,preload if its 4.1.2 and then flash Roms. Always works ok with out problems. Only time iv used kernel nuke is to get of Apollo kernel. Glad you sorted your problem out. :thumbup:
Hi Team,
I have a GT-19100T which had the carriers firmware (Vodafail AU) 4.1.3 (rooted) running with no problems until recently (2 wks ago), prior to the fault I have had this phone for years no glitches great phone for its age.
I had let the battery drain, upon re-energizing the phone and attempting to turn on the wireless i noticed it just reported "Turning WI-FI on" and the toggle switch was greyed out. this would last all day. switching the phone off and on would not stop the process of the phone attempting to turn wi-fi on.
I immediately went searching forums and people suggested hardware fault or perform factory wipe through CWM.
Troubleshooting I have performed so far is:
- factory wipe and cache cleanup (not resolved)
- flashed to CM 10.1.3 (not resolved) (multiple times)
++++
OS: 4.2.2
Baseband: 1900TDULP4
kernal version: 3.0.64-cm-g9c2e2bc
++++
I have found from research that the Bluetooth and wi-fi are the same module (I maybe wrong) and Bluetooth is working fine.
So this leads me to suspect a software/firmware fault.
I'm currently downloading I9100TDVLSM_I9100TVAULSF_VAU.zip from (sam mobile) the latest release for this phone from the carrier to see if firmware will resolve the problem.
In the mean time any suggestion, advice, help or solutions would be greatly appreciated.
Maybe if someone knows of a file i can flash specifically for wi-fi module that I could try.
Thanks in advance

Hi Team,
I have a GT-19100T which had the carriers firmware (Vodafail AU) 4.1.3 (rooted) running with no problems until recently (2 wks ago), prior to the fault I have had this phone for years no glitches great phone for its age.
I had let the battery drain, upon re-energizing the phone and attempting to turn on the wireless i noticed it just reported "Turning WI-FI on" and the toggle switch was greyed out. this would last all day. switching the phone off and on would not stop the process of the phone attempting to turn wi-fi on.
I immediately went searching forums and people suggested hardware fault or perform factory wipe through CWM.
Troubleshooting I have performed so far is:
- factory wipe and cache cleanup (not resolved)
- flashed to CM 10.1.3 (not resolved) (multiple times)
++++
OS: 4.2.2
Baseband: 1900TDULP4
kernal version: 3.0.64-cm-g9c2e2bc
++++
I have found from research that the Bluetooth and wi-fi are the same module (I maybe wrong) and Bluetooth is working fine.
So this leads me to suspect a software/firmware fault.

I have same problem few weeks ago when my galaxy on Stock Rom 4.1.2.
Later, I try to reflash again through Odin, then install CWM and I flash CM 10.2 4.3 through CWM and it solved.
I think you should try to flash Newer Rom version, example CM10.2 or SlimKat.
Good luck

Thanks mate for your reply,
I installed cm 11, this did not resolve it.
need the file for the radio/modem, i'm hoping this will fix it but not sure exactly what I am looking for.
**Update***
Just finished installing I9100TDVLSM_I9100TVAULSF_VAU (latest release from Sam Mobile) 4.1.2
Still wi-fi not working.
will try and install cm 10.2 on your recommendation huytrandinh
Okay latest nightly of CM is installed cm-10.2-20131216-NIGHTLY-i9100.
Still has not resolved the wi-fi issue.
anyone have a potential solution?
there is this post for S4, but obviously only viable for S4

Try to flash a modem using odin,
Sent from my GT-I9100 using xda app-developers app
Modem won't solve the issue as WiFi/BT drivers are in the kernel on the S2. OP was on the right track, but for whatever reason a clean install of stock didn't fix the problem.
Maybe try the 3 part firmware in Hopper8's Odin Troubleshooting thread, then a clean install of the Voda stock rom after that ?
There's 'WiFi fixes' (which are actually the LTE modem) for the I9505 as it actually has two separate modems, and the LTE modem also controls WiFi (which isn't the case with the S2 as per my comment above).

Have been trying that, still no success.
have spent all day trying to find a solution
I tried the modems from here:
##hxxtp://###.veyka.co.uk/sgs2/radios/## (unable to post links ffs)
and few other random links from the forums

Thanks Mistahbungle,
I checked out that thread http://forum.xda-developers.com/showthread.php?t=2345831
Nothing i could really use.
But I did try a few other kernels:
Siyah-s2-v5.0.1
Unfortunately as soon as flashing with other kernels the screen would go black after the initial boot logo.
Only way to resolve it not booting into the OS was to roll back to:
1. GT-I9100_JB_ClockworkMod-Recovery_6.0.2.9 (flashed with odin)
2. flash CWM-SuperSU-v0.97 with CWMRecovery
3. install cm-10.2-20131216-NIGHTLY-i9100
4. then your general cleaup through cwmrecovery
I'm not sure if I'm doing something wrong when trying to apply another kernel.
anyone able to offer assistance please with right kernel?
cheers
**Update**
Just found a post in that thread - http://forum.xda-developers.com/showthread.php?t=2345831&page=6
Will try the 3 part rom XXLSJ for GT-I9100.
Fingers crossed
Yeah, that's what I suggested in my PP. Sorry, seems the 3 part was on HotFile & Hopper didn't have his own copy up somewhere.
The rationale was - there's possibly something from a previous installation causing your issues, and flashing the 3 part would wipe your phone. I realise you've done this manually, but at this stage you're fast running out of ideas before you declare it a possible hardware issue, and it was worth a shot.
So...What I'd try is - while you have a rooted phone, go into CWRecovery and format everything/ (not EFS though obviously, or your external card if you have one), then try re-flashing whatever stock firmware you have with Odin in download mode.
Edit - Also, maybe do a Google search for that 3 part firmware (details are still on Samfirmware, just that the files are gone), you never know, you might find it somewhere.

Okay just finished testing the rom by installing it via odin (3 part)
still has not yielded any favorable results .
Little disapointed as this was a great backup phone and served for the past 12 months as a mp3 player
Guess as they say; It is all planned obsolescent which is fracked ...
Thanks for the suggestion/help anyway.
I know this is an old thread but my gs2 had this problem and I was able to fix it. Using es file explorer made my way to /data/misc/wifi pulled up the properties to wpa_supplicant.conf and changed group to wifi...then wifi finished initializing...hope this helps somebody
Sent from my SM-T310 using XDA Premium 4 mobile app
for consideration.
I have this phone. the GT-i9100. Had this issue also. I took it apart. The little onboard battery had blown and corrosion got all over all it.
and guess where WiFi hard is. Right Next door. I cleaned it up real good. Put it back together and WiFi came back to life.
So give it some thought guys.
Hello.
I was able to fix the random reboots i had with flashing prerooted zip via TWRP, this apply also on the new 26.1.A.3.111, only tested on E2306.
1. Must backup your data. You are gonna wipe it
2. Use flashtool and downgrade to a rootkitXperia rootable firmware. I used 26.1.A.1.112 but other rootable should be the same. (wipe data may not be necesary in this step but i did it just in case)
3. When flashing done, root the device with rootkit, and install TWRP
4. Use xperifirm to download the 3.111 FW then create the prerooted with its system.ext4 and kernel.elf
5. Flash the zip via TWRP, wipe dalvik, then start the phone and check that you have superuser, and go about phone to make sure everything went well and your in 3.111 with its kernel also.
6. Use flashtool again to flash 26.1.A.3.111 but you this time you must EXCLUDE SYSTEM and KERNEL to keep the root, in other words your gonna flash everything but kernel and system so be sure you ticked them, also should wipe data so you can start fresh and avoid possible incompatible things.
7. Let the phone starts, mine took around 10 - 15 min. You should now be in 26.1.A.3.111 with root and no random reboots. So far im using it since 12 days and no reboots nor system hangs, ive updated all apps via playstore, and even downloaded several 500Mb+ games and its working really fine

Sorry for this guide that isnt noob friendly, im doing it quite hurry because im too busy with work but i wanted to share what worked for me with everyone. If this works for you too and someone wants to do a better noob friendly guide with links and such go ahead it is ok.
[NOTE]Random reboots seems to happen when there are diferent modem versions. Special thanks to @sergioslk who discovered this.
Of course, all credits to the respective developers who worked really hard on this tools for us. Thanks devs.
Hey, thanks. I had 26.1.A.2.167 rooted, so I just installed 3.111 with data wipe through prerooted zip on top of 2.167, and then reflashed everything except for kernel and system (also data wipe here) like you wrote in your post. So far so good - almost 30h without reboot, which is far better than before.
Hm, didn't work for me also with 3.111 I reflashed (using stock 3.111 from xperifirm) excluded kern and system but it is still randomly rebooting when installing gapps.

Did you first flashed via TWRP the prerooted zip you created with system.ext4 and kernel.elf extracted from 3.111 FW? did you wiped data after completing flash? which version of FW you had just before flash 3.111?
Yeah, I did as you say. My phone orig had 2.167, but it upgraded itself recently to 3.111, then I downgraded to 1.128 to root, before using the prerooted TWRP zip (with system.ext4 and kernel.elf extracted from 3.111 ftf) to upgrade back to 3.111.
EDIT: I think something went wrong when I created the ftf bundle from the files downloaded from xperifirm. I repeated the whole process and now I'm not seeing the random reboots (at least for an hour with quite a few apps installed and updated) ....So yeah in summary many thanks for this ...It would be nice if it was mentioned on the main how to thread.

Thanks so much for posting this. I had thought of doing this myself but quickly ruled it out because I thought it was a dumb idea (no offense) and wouldn't work, but after hearing of your success I thought I'd give it a try anyways and I've been powering through a ton of app installs/updates and haven't had a single reboot so far. It sounds to me like this is the key.
I'll post an edit after a few days to let you guys know how it holds to my personal test of time.
Thanks again!
Update:
Well, it's been nearly a week now and I've yet to experience a random reboot. This is definitely the fix we've all been waiting for! I hope this knowledge can be spread to all who have been plagued with this issue!
the random reboots are related to different modem versions, that is why phone reboot when using a hi-speed wifi connection, i said this previously but no one matters :'(

Hey @sergioslk,
Thanks so much for your contribution. I found your post about this problem but it was kind of hard to read whereas the original poster here went into a bit more detail. Sometimes that's all people need, is a little more information. I'm sure you've made other contributions to the community that have been extremely valuable.
To reitterate, this is definitely the fix to the problem we've all been facing when it comes to using the pre-rooted zip to get root on the latest version. I had suspected this to be the problem awhile ago but couldn't really figure out how to fix it.
Thanks everyone for all your hard work!

Oh dude many thanks for this contribution, i havent readed your post before, but now i can say theres a know reason why the random reboots occurs. Im not an expert in android, i just tried this as a last hope, ive tried everithing, no google account, no wifi, no moibile data, no sdcard, deleting all bloatware, untouching bloatware, a lot of wipes..... and this last one for some reason worked but i wasnt sure why untill now. Thanks again!
