[Galaxy Tab 10.1 Android Development] pershoot:
disable setcpu (and any overclock) and reboot. set your wifi to never sleep.

put the device to sleep and come back to it later on.

try to get the log as quick as you can if it occurs again. i would like to see a better log of the incident.

if it does not occur again, move to 1.2GHZ and then observe. stay with ondemand, min 216. leave wifi to never sleep.

also ensure you are not using any apps which would cause issue (another member found the touchscreen app was causing issues for him).

Does this drain the battery?
[Galaxy Tab 10.1 Android Development] pershoot:
your device is running faster and with more voltage. it is bound to get a lil hot. i myself havent felt anything that is alarming tho.

thermal throttling is enabled, and it will clock down itself, if things get too hot.

you can also setup profiles in setcpu as well (im unsure if the temp reported in setcpu is accurate tho).
[Galaxy Tab 10.1 Android Development] EvoXOhio:
So i installed kernel earlier today, been running fine. Just turned the screen on after sitting out off unplugged and it took 5 tries to unlock iit, and it unlocked at a snail's pace. I swiped a whole bunch and got it to switch screens once. Tried to correctly power it down but it locked up. I had to hold the power button for 10 seconds to get it to forcefully power off.

I was running at 1.2 ghz with a sleep profile. I just deleted my sleep profile to see if that was the problem.
[Galaxy Tab 10.1 Android Development] pershoot:
Some people have sleep/wake problems with setcpu.

Stop using it and echo in your values to cpufreq.

[Galaxy Tab 10.1 Android Development] EvoXOhio:
Well I set it down for awhile and went to pick it up, and the screen wouldn't even turn on. Tried it 10 times. Had to hold the power button down for 10 seconds again to force it off.

This is even worse than what happened earlier. I am going back to stock until the next release assuming it fixes the waking up issues.

Looking forward to a new version.

Edit: damn you lol. You posted a new version right as I posted this. Does the new version address the wake issue at all?

uninstall it, and then flash the refresh.

be sure you are stable at the frequency you are intending to run at.
[Galaxy Tab 10.1 Android Development] EvoXOhio:
Done. However this means I've changed Max speed, changed kernels, and uninstalled setcpu. So if its fixed now I won't know what did it. Now I need to read up on changing frequencies directly without setCPU. Thanks.

[Galaxy Tab 10.1 Android Development] The Root:
He shouldn't have wiped...
[Galaxy Tab 10.1 Android Development] makbil:
Theoretically it should. I OC to 1.2 GHz/On demand and can't really see any difference because the tab only goes to the higher speed if needed. On the other hand, a process that could take 1 sec on 1 GHz most of the time will take less on higher speeds so you win some loose some. I wouldn't consider battery consumption very relevant for OC'ing. If your tablet is stable at higher speeds give it a go.

I just headed over to the Droid Basement to download the release kernel and saw a note that Jabra BT headphones not working. I tested my Jabra Halo and it does work, however start/stop and volume functions do not but no problem with the audio.

One more thing I noticed, when I switch on or off Bluetooth, all wireless connections are terminated (wi-fi and 3G) then they are reestablished.

Still on tt7 but that shouldn't make a difference right?
[Galaxy Tab 10.1 Android Development] pershoot:
Your looking at the wrong posting (notice the headline/kernel -version, device name).

This tab is called galaxy tab 10.1

[Galaxy Tab 10.1 Android Development] makbil:
Yeah, I just noticed that I was reading the wrong one. :o

Not too sure if the disconnect issue was there in previous kernels. I can flash 102411 and check.

Check both 102411 and 112011.
[Galaxy Tab 10.1 Android Development] makbil:
112311 (22:00:47 EST) gives me the problem when I do the following sequence:

Turn on BT -> OK

Connect Jabra Halo headset -> All wireless connections are turned off then back on.

I need to do the exact sequence with 102411 again. Stand by.
[Galaxy Tab 10.1 Android Development] pershoot:
1120 then 1123
[Galaxy Tab 10.1 Android Development] makbil:
No wireless disconnect on 102411. Now to try 1120.

1120 is good.

---------- Post added at 05:26 PM ---------- Previous post was at 05:17 PM ----------

Back to 1123 but not getting it right now. Had it twice but not this time. I'll try some more on this kernel and see what happens.

Edit: Disregard this for now. It may have been my tab temporarily acting up. All seems to be good.

Wifi issue

Hi,

I have wifi problems using this kernel.

I set wifi to turn off in standby (screen off), when I turn on the device wifi does not reconnect anymore.

I have stock ROM P7500XWKK4 and Kernel 2.6.36.4 from boot-cm_2636.4_p4_ux_hc32-oc-xtra-vfpv3-d16_fp-112211.zip

Using the older version boot-cm_2636.4_p4_ux-oc-xtra-vfpv3-d16_fp-112011.zip the wifi issue is gone but the autorotation of the screen does not work anymore.

I run at 216/1400 ondemand.

Any ideas?
[Galaxy Tab 10.1 Android Development] pershoot:
wifi is the same module between hc3.2 and non hc3.2 in those builds. it has not changed between 1120/1122. 1122 was just a maintenance update for MPU3050.

you should keep wifi to never sleep. that has been a possible longstanding issue with wifi (which causes other wierdness in HC).

at any rate, try to get an update for your rom, as was the case for 7510 users for wifi.
[Galaxy Tab 10.1 Android Development] Hulzer:
But it's 100% repeatable. If I use 1120 wifi reconnects after standby (waiting 20min.) but 1122 doesn't.

And with 1120 autorotation does not work, with 1122 it works.
[Galaxy Tab 10.1 Android Development] pershoot:
the 1120 you are using there is for hc3.1 not for hc3.2. not a valid test. the new MPU has a chance to play as a variable in the mix.
[Galaxy Tab 10.1 Android Development] pershoot:
if you want to validate this, roll back to 3.1, and flash 1120. observe. then flash back to 102411 for hc3.1. observe. then report back.

if that is done, then it can be investigated, if needed.
[Galaxy Tab 10.1 Android Development] pershoot:
on UEKMN (OTA yesterday) for 7510, on -1122, wifi sleep when screen off works ok.

screen off for 5 mins, wake up, i see it connected and data arrows move.

tested three times.
[Galaxy Tab 10.1 Android Development] Hulzer:
If think P7500XWKK4 has the same problems as the first HC 3.2 for 7510. Maybe that's the reason why Samsung pulled it off from the server. Maybe it will come a second HC 3.2 update for 7500.
[Galaxy Tab 10.1 Android Development] notfaded1:
did u flash back to stock before

Did you flash back to stock before the OTA?

Wondering if you can just do OTA then flash new -1122 kernel and be ok and even have root remain?

Or if you didn't P has anyone else tried it?

On my Gtab 10.1 P7500, I was using Pershoot kernel (boot-cm_2636.4_p4_ux-oc-xtra-vfpv3-d16_fp-102411) on 3.1 (many ROMs) and everything sound working well (thanks for that).

Now I am on 3.2 (stock P75000XWKK4), I've tried boot-cm_2636.4_p4_ux_hc32-oc-xtra-vfpv3-d16_fp-112211, but seams not work.

- Can not UC with setcpu (stuck at 1000Mhz)

Need advice

I have 7500 on stock 3.1 rom

Would like to install Pershot's Kernel with Overcome 2.1 Rom

1) I want to start with blank TAB so I don't need any full system backup. But maybe I have to save some important data (EFS backup or something else)?

2) What to flash first, Kernel or ROM?

Additional noob question :) This Kernal is improved HC 3.1 base adopted to support HC 3.2? If yes - any plan to use HC 3.2 basis in the future?

Thank you

[Galaxy Tab 10.1 Android Development] nightmarebadger:
Flash ROM first (ROMs almost always include a kernel which overwrites the one you have installed before flashing), then Kernel.

For flashing Overcome I'd recommend going with their instructions, they are well written and noob friendly. (Basically, you need to flash CWM first, then flash ROM and Kernel through it).

After that, just flash kernel and everything should work.

Which important data is that? Most stuff can be saved via synchronising with Google, and quite some app data is saved on the "SD card", which doesn't get deleted with flashing a custom ROM.

If that doesn't suit your needs, try Titanium Backup (you need root for that) or something similar.

And don't worry about the kernel, it works awesomely, as for what is the base kernel, the author already answered that :)
[Galaxy Tab 10.1 Android Development] nebvanbgd:
Thank you very much !!!

Overcome ROM is flashed successfully :)

Will continue with Kernal.

Unable to Copy files via USB between Tab and PC

Hi OP/All,

I have 7500 on stock 3.1 rom and rooted only, I flashed this kernel yesterday to get the USB charging and Overclocking and its been great, But I have just noticed that I am unable to copy files to the Tab and away from the tab.

I made a backup using CWM before flashing the kernel and I was trying to copy the image file to my pc but unable to , also unable to copy music video etc from the tab storage to my computer.

I get the error shown below:
[Galaxy Tab 10.1 Android Development] nightmarebadger:
Do you have USB debugging enabled? It's under settings -> applications -> development. The computer shouldn't even be able to see the device with debugging disabled but it might be worth a try :)
[Galaxy Tab 10.1 Android Development] saayinla:
Yes I have it enabled and still the same result. I normally do not have to enable it to copy files as once USB is plugged in I can see the tab on the pc and copy files.
[Galaxy Tab 10.1 Android Development] pershoot:
launch usbdeview (as admin; http://www.softpedia.com/get/System/System-Info/USBDeview.shtml), highlight the driver being used, disconnect tab, purge the driver, connect tab and ensure usb debugging is off (if you are using 3.1), then connect tab. once it reinstalls the driver you will see it via MTP.

Thanks in advance.
[Galaxy Tab 10.1 Android Development] pershoot:
use ADB to pull the backup (you can do it when in recovery if you like).

adb shell mount /data (if in recovery)

adb pull /data/media/clockworkmod/backup/DATED_FOLDER_NAME .

you can certainly copy files from the tab, just not the backup because of permissions set on the backup (most likely), via MTP.
