ok, now with [ROM] ISI-GALAXY 10.1v 0.3v with pershoot's kernel smooth [08/08]

* booted from stock recovery (fastboot boot recovery.img) and did a full reset

* booted into CWM (adb reboot recovery)

* installed ISI-GALAXY.0.3v.zip (adb push ISI-GALAXY.0.3v.zip /sdcard/ ,then install from sd card in CWM)

* booted up the tab into honeycomb

* back to recovery (adb reboot recovery)

* installed boot-cm_2636.4_p4-test1.zip (adb push boot-cm_2636.4_p4-test1.zip /sdcard/ ,then install from sd card in CWM)

* booted into honeycomb

* adb shell uname -a : Linux localhost 2.6.36.4-cyanogenmod+ #1 SMP PREEMPT Tue Aug 9 14:43:16 EDT 2011 armv7l GNU/Linux (which looks to be ok)

The problem definately does not go away in this setup (loosing 2%/minute).

I will now start making those logs.
[Galaxy Tab 10.1v Android Development] m3taverse:
Ok, i followed your instructions for creating the log files.

I can't have it run for an hour, at least not with the screen on, so this is from half an hour.

This is what i did:

* Booted up Corrie's rom

* Battery at 78%

* adb shell dmesg >dmesg_1 (battery at 78%)

* unplugged usb cable

* let it run for a while, a bit with the screen on, a bit with it off. Within 17 minutes i'm on 27%, so i thought that would be a good time to make the second file

* plug in usb cable, adb shell dmesg >dmesg_2 (battery at 27%)

* unplug usb cable, switch off device, plug into mains

* battery graphic appears, but it is shown completely empty and there is no animation at all

* unplug from mains, battery graphic dissapears but device does not boot (which i think is not the normal behaviour). I have to long-hold the power button for it to come back on.

When i boot into Honeycomb, i can just see the battery indicator being 70%+ when the tab briefly shows a power warning and then instantly shuts down the tab.

* i plug it into usb, and boot it up

* boot into honeycomb, which now does not shut down, and the device reports to be at 77% battery

* adb shell dmesg >dmesg_3 (battery at 77%)

I'm using 1.0.3 with pershoot's last kernel and I don't have any problem.

Are we even sure that it's related to the kernel? Only some people are having that battery drain problem and some are reporting that drowngrading doesn't fix anything.
[Galaxy Tab 10.1v Android Development] m3taverse:
Also check out this screendump of Honeycomb's battery usage thing... the weird spike in the middle is where i booted it up and it briefly reported to be at 70%+ and then immediatelly decided it was really empty and shut down.
[Galaxy Tab 10.1v Android Development] tinglez:
Anyone tried flashing to stock, running down battery, and then flashing 3.1 rom while connected to a charger and leaving it to charge to 100 percent after the rom has been loaded?

I'm also having a wakeup problem where after a few hours the tablet will have a black screen and be unable to do anything for a good few minutes before it wakes up.

re flahsed from stock after wipe and still have volume issues with headphones plugged in, and still can't get windows explorer to show my tablet (grr)
[Galaxy Tab 10.1v Android Development] pershoot:
usb charging appears to be detected. iwall charging that appears broken (not from your log but another log from another devie).

funny thing is, it reads the battery without issue.

investigating..
[Galaxy Tab 10.1v Android Development] twigster:
Hi Pershoot,

Unfortunately I cant see any better battery usage on my tab after trying your test kernel, and not on Corrie's ROM so havent included logs for you, my data package is already under strain this month.

Funny thing, upon seeing your post quoted above, I thought about it, I had my tab plugged into my PC USB last night while I was working with it (to be able to work with it), and that included extensive WIFI transfer for about two hours. The battery did decrease but only slowly, while it was plugged into the USB. However I stopped using it when I plugged it back into the wall charger, so I cant confirm if I would have still been able to use it as I had been, while it was charging in the USB.

And when I tried it later in the night without being plugged in to charge at all it died quite quickly again.

So maybe the USB charge is fine, even though it shows that cross over the charge symbol, and we are thinking it is charging on the wall because it shows the normal charge symbol, but it actually isnt. When I get home tonight i'll test a little.

Id be interested to hear if others have tried this and their results.

And i agree with your comment on the battery being detected / read fine because in OSmonitor (which reads a constant 4mv on my tab now, by the way) it showed the USB charge as detected. Unfortunately, once again, I didnt check OSmonitor while plugged into the wall. And it states that the batteries health is good, which if it didnt detect the battery, wouldnt it show an error of some sort?

My next question then, is why does the battery issue remain when we flash back to stock or other rom versions? It must be deeper than just the ROM and Kernel.
[Galaxy Tab 10.1v Android Development] CorrieM:
I am not experiencing the issue with battery drain or charging, So it could be a device issue, if you are experiencing it on stock as well.

I left my tab on standby with wifi on at 10:00 last night, at 97%, this morning at 07:00 it was at 94%.

My device battery died on me on Monday night, battery was at 2% when I started to charged it and it did charged back to full in about 6-7 hours if I remember correctly.
[Galaxy Tab 10.1v Android Development] seo:
the thing people reports is very very strange. couldnt reproduce it. I have something like 6 to 7 percent bat drop for a hour on screen always on plus music playing and wifi/3g on. never more than 7%. seems like there are no two exactly same tablets :) pershoot can it be caused by latest tegra dc patches ?
[Galaxy Tab 10.1v Android Development] m3taverse:
I switched off the tab and plugged it in the wall charger. The battery graphic appeared, again showing completely empty and no animation.

After i slept for a few hours i switched on the tab (again needing long-press on power button to wake it). I then set out to run an hour long test, like you asked for originally, with the screen off for the duration of it.

So these are the logs for that:

00:00 - battery at 96% => dmesg_1 -> unplug usb cable

00:30 - battery at 86% => dmesg_2 -> unplug usb cable

01:00 - battery at 85% -> switch off device, connect to wall charger. device shows battery graphic, showing to be completely empty and no animation -> disconnect from wall charger -> i need to long press the powerbutton to get it to boot -> although showing a pretty full battery bar, android shows a power warning and then instantly shuts down -> connect to usb and boot

01:05 - battery at 92% => dmesg_3
[Galaxy Tab 10.1v Android Development] tigerminx:
I think I may have resolved the battery issue, well at least for Stock 3.01 anyways. Here is what I have done:

I was running 1.04 when I first experienced this issue, I think I was actually the first to report the strange behaviour. I flashed back to 1.03. and the problem persisted (Massive battery loss, and then rebooting, I would recover almost all of what was lost.) Flashed back to 0.8, and the same thing continued. At this stage I thought, I must have a faulty charger or something...

I then decided to flash back to Chainfire's BUKDF 3.01 Stock via Odin, thinking this would definitely solve my battery issue. This wasn't the case, booted into the OS and lost about 30% within about 5 minutes of use. So I presumed it was a calibration issue. So I drained the TAB completely. Rebooting, all the time until I eventually couldn't even switch on the TAB anymore, (When I couldn't boot into the OS, I would just leave the TAB in the Fastboot, or Download menu !!!)

I then charged the TAB while the device was powered off, and what I noticed was something different, I was actually seeing the charge animation this time, where as before I would just see an empty battery, and if the screen powered off I would just see a blank screen, when powering back on.

It finally charged to 100%, turned on the TAB immediatley booted into CWM, and wiped Battery Stats. Booted into OS, and ran the Battery Calibrate APP from the Market to clear battery stats again (just to make sure).

I can safely report after almost 24 Hours, and quite a bit of use I have only lost 16% battery life. (Not bad I say) however this is still on Stock 3.01.

Hope you guys come right as well.
[Galaxy Tab 10.1v Android Development] m3taverse:
thanks for that tigerminx... i actually tried that route (i've wiped battery stats through CWM and Battery app, and tried to restore stock through odin), but for whatever reason i cannot get odin to get past SetupConnection (i've tried on 2 machines, one of which doesn't have any of my dev and weirdo tools), and i wasn't as persistent in actually getting the battery to completely run dry. But perhaps returning to stock isn't even required, it seems like you're sort of resetting the battery.

What is OSmonitor reporting now about your battery?
[Galaxy Tab 10.1v Android Development] gruhlstein:
odin never worked for me also... is there anyone who knows an way back without using odin?

thx
[Galaxy Tab 10.1v Android Development] tigerminx:
Last night I noticed that it was 3mV before going to bed. This morning it's showing 4mV. Not sure if that has anything to do with the issue though. I am certain though, that my issue has been resolved.
[Galaxy Tab 10.1v Android Development] sitiweb-italia.com:
Hello Sorry I am new, but I wanted to speak my mind

I have the Rom SEO 1.03 and the battery only lasts about 48h wifi, 3g using I do not know do not use it in that mode, only problem is I do not see the icon when it is charging the battery recharge

greetings
[Galaxy Tab 10.1v Android Development] scarflex:
I try to make full discharge, i left tablet for almost tree day's without of power to show me 0% couple of thimes,and turned off himself, but when I turned on charger snow's me 36% a start to charge.

I will charged to full again and trying something else...
[Galaxy Tab 10.1v Android Development] m3taverse:
try like tigerminx said: boot up honeycomb untill it won't boot anymore, then boot to bootmenu (volume button down), and then leave it on that untill the tab will not actually start anymore.

I'm actually on that last step myself now, waiting for the bloody thing to be out of juice.
[Galaxy Tab 10.1v Android Development] tigerminx:
What you could also try, which worked once for me, is if you can't boot into the OS (Gets to log in screen and immediately switches off), boot with charger plugged in, reboot to CWM, and delete battery stats file. Then unplug charger, and see if you can boot to OS. In my case the battery showed 99%, then about 15 minutes later switched off, and I was then unable to turn the TAB back on. Might speed up the process :)
[Galaxy Tab 10.1v Android Development] m3taverse:
there's prolly something more cleverer that can be done, like

fastboot boot cwmrecovery.img (boots cwm, which in turn gives access to adb)

and then adb shell some-crazy-intensive-task ... but i dunno if that process would end when you unplug it from usb, probably does, but perhaps some-crazy-intensive-task could be started as a background process i think (&). Or maybe shell is not available from cwm adb, dunno.

Anyways, i'll report back soon.
[Galaxy Tab 10.1v Android Development] pershoot:
so your all telling me this was not a kernel issue?

because im literally pulling my hair out here.

nothing ive brought in should effect this at all.

the other devices using rhe same source do not have this issue.
[Galaxy Tab 10.1v Android Development] pershoot:
now that you know how to sort this issue if it comes up again.

go back to 3.1, and then flash -test1 over it.

report back on whether you can charge from wall or not.

whether you can usb charge.

whether you get excessive battery drain.
[Galaxy Tab 10.1v Android Development] pershoot:
4mv is normal. this is what is shown on 10.1 wifi, in osmonitor.
[Galaxy Tab 10.1v Android Development] pershoot:
forget -test1.

stay on -0807, and test this stuff out.
[Galaxy Tab 10.1v Android Development] tigerminx:
What's the best practice for flashing a new ROM. Fully charging the battery then flashing, or can it be done during any point, provided you do some sort of battery calibration afterwards? I must say all this battery nonsense has got me a little confused especially since I am not sure what caused it.

So to answer your first question regarding kernel, I'm not sure. But the problem definitely came along when I tried charging on 1.04, and in the changelog Seo mentioned a new kernel was implemented.
[Galaxy Tab 10.1v Android Development] pershoot:
it can be done on any point. you should have some battery tho when flashing.

im going to rework the kernel for this device to make it a lil less hacky using this src. then all this stuff should smoothen itself out.

ill pm you with a test when i get some downtime from work to do this.

in the meantime, im going to pull the -0809 kernel for 10.1v. -0807 should work fine (as you've tested this already on your device).
[Galaxy Tab 10.1v Android Development] tigerminx:
Thanks, is the -0807 from Seo's 1.03 ROM?
[Galaxy Tab 10.1v Android Development] pershoot:
no idea whats in there.
[Galaxy Tab 10.1v Android Development] wsmit:
Hmmm,

Let me also put my head into the hornet's nest..

My Tab was fine on 1.0.4 until yesterday when I enabled the power saving mode. Then something messed with the battery stats. Last night, despite a day's use the battery was on 100%. Left it off the charger overnight, and this morning it was still at 100% Got suspicious and plugged in the charger. Battery went down to 24% almost immediately. Unplugged it after 15min and came to work. Battery at 35% when I got here. Left it on the charger for 2 hours. Battery at 36%. Rebooted the tablet. Battery indicated as fully charged afterwards. etc. etc.

Finally disabled *all* the power saving features, booted into CWM and cleared the battery stats. 1 hour later and the battery appears to be holding fine. Have my fingers crossed..
[Galaxy Tab 10.1v Android Development] tigerminx:
Sorry to sound stupid, but where can I get the -0807 kernel from? From droidbasement.com?

[Galaxy Tab 10.1v Android Development] djden:
when i noticed battery drops

I sure remember my battery drops started when it was flashed to 1.0.4 and after that i installed SETCPU, and like after 5 minutes when i was changing some Mhz from 1000 to 1400 and back and switch between interactive and ondemanod ,did some playing with setcpu have anything to do with? because i also played with setcpu on 1.0.3 and dont have seen that problem, so kernel or setcpu is involved??

maybe you have something on my info thats when i noticed first time drops

...time will tell, can set cpu settings not do any damage to the battery for sure? in combination with diffrent kernels?

btw thnx for this rom and this interesting forum

Updated to 1.0.5 - Reboot Loop

Hi Guys,

I've installed version 1.0 successfully and decided to install 1.0.5 as the comment stated it is for 1.0 only.

Now my tab is in a reboot loop. The first screen would show, then it would reboot then back again.

Anyone installed 1.0.5 successfully?

The battery sickness is gone, will see how long...
[Galaxy Tab 10.1v Android Development] m3taverse:
Ok, i've done all this now, and i installed corrie 0.3. It appears that completely draining the battery, and then charging it full does in fact solve the issue, at least temporarily.

In corrie 0.3 there are some power related issues: When device is off and connected to wall charger, the charge animation will no longer appear. When the device is on and connected to a wallcharger and the device wakes up from sleeping, it will now report what must be an incorrect charge value... it looks like it hasn't received the charge while sleeping. I can imagine this causing problems if it affects battery stats.
[Galaxy Tab 10.1v Android Development] pershoot:
any 10.1v folks awake that want to help test?

ive started this process of deconstruction/reconstruction.

lemme know.
[Galaxy Tab 10.1v Android Development] Crudeoil:
I did your procedure without flashing flashing 3.01 tho. I'm now waiting till its full charged for turning it on.

This is what I did..

- (on corrie's rom) flashed 080711 kernel

- full discharge battery till it was completely dead -> did as tigerminx did

- while off, plugged it to the wall

It showed no animation, just the battery icon with no movement..

In 3 more hours from now it'll be 10 hours since charging. Only then i'll turn it on and flash the newes Rs's rom with last update and hope the best..
[Galaxy Tab 10.1v Android Development] Foggcas:
The only time I've ever seen the charging battery icon animated (green bar filling up) while the tab is off was on 3.0.1. I've never seen it on any of the ROM's released by seo. The TAB has still charged though...

Hi to everybody,

Following your instructions, I'm working with my 10.1v updated to version 1.03 and the 1.05, withou any problem since 3 days.

Battery is ok: tab is on since 2d 19h 43m.. without any strange restart, freeze or else.

Battery charges both via USB either via AC supply.

No problem with 3G connection.

I use 90% in wireless mode.

No problem with the camera resolution after final update.

The only one thing I've not tried is to put the module to send SMS (I don't need it) as, for the moment, I've read it's not perfectly compatible.

Finally, I'm not having all the troubles I'm reading on this pages....

Thank you to seo and peershoot ! ;)

loading screen failure

Hi guys,

I got a problem. I tried flashing this ROM. Got working fastboot, unlocked bootloader and device was rooted. Then I flashed it with CWM, now all seemed fine, but now i am stuck with loading screen "Samsung Galaxy Tab 10.1v" only those lines, nothing happens. I then tried to get it back to factory settings, worked aswell, but still stuck on loading screen. I cant do anything anymore.

Any tips?
