For hardware accelerated problem it's related to multimedia co-processor/ducati and ion memory mapping. I already fixed ducati memory mapping but too tired to analyze ion related part. The good news, the new ducati firmware applicable to CM without negative effect to hardware accelerated media and I got more RAM :D WiFi will be the last thing to be fixed. The target has been reached for this day, dual boot stock 4.2.2 and CM 10.2 :victory:

Hello guys,

Can i flash the exFAT mod in PAC rom? Does it work?

I can't use NTFS, my tablet doesn't see the memory, only fat32..

EDIT: Just try myself

i've maked a backup, flashed the zip and try the memory formatted under windows in exFAT and it works!

A question: why i need USB OTG Helper?

To connect an external drive that have other file system?

Is the same as NTFS Mounter which supports NTFS/FAT/EXT2/EXT3/EXT4 external USB stick or HDD?

Thank you!

EDIT2: WHAT THE...!

i see only now that the last kernel update support already the exFAT! But not in my case! Isn't a good idea to have flashed this zip?

Damn :(
[Galaxy Tab 2 7" Android Development] Skazzy3:
It says for cm10.2 not pac rom
[Galaxy Tab 2 7" Android Development] Aliendex:
Lol, thank you.. So i can use my exFAT memory normal than before?

I'm copying right now all my file to the sd thanks to an usb adapter (19 GB)

Good morning!

Again thanks [MENTION=3208754]codeworkx[/MENTION], omapzoom.org, and CM Team. Hardware accelerated media and camera issues fixed! Yea...yea..yes.. :cool:

Source of my solutions: https://github.com/TheMuppets/proprietary_vendor_samsung/blob/cm-10.1/p31xx/p31xx-vendor-blobs.mk and http://omapzoom.org/?p=platform/har...9;hb=707e301de8b52780a7f0e88e6f25ac919c23671f

It's hard created a single kernel for 4/5 types of ROM but nothing is impossible.

I have 2 options:

1. Modify the kernel part but this solution will break my dual boot rules, my kernel will be not compatible to 4.1.2 and CM

2. Reuse 4.1.2 vendor binary blobs, this is the best solution for now
[Galaxy Tab 2 7" Android Development] antutu:
seems like option 2, is the best we can get now

but kernel modification will be available for next build, isn't it?
[Galaxy Tab 2 7" Android Development] CodyF86:
I agree also; I think you'll have less headaches reusing 4.1.2 blobs...at least for now. :good: :fingers-crossed: :)

Ketut@ I need ur advice..bit off topic.. Yesterday I Installed mythi deodexed rom.. But it was too too too slow for me.. Nothing was opening quick.. Even the messaging app takes lots f time to open n wen it get open.. It's get impossible to type n send messages.. Phone was performing with lots trouble.. Then I install psn deodexed Rom.. Same prob.. But still better than mythi one.. I restore approx 30 apps using titanium backup.. Out of which only 3 restored with data.. So m not being able to understand the problem.. Y the 4.2.2 get hanged or perform so slow for me.. Is it related with titanium or kernel.. Pls help me.. Do I need to install original 4.2.2?

Edit - sir I jus read ur comment in mythi forum regarding my ques.. Sir please upload ur deodexed rom for me.. If pos.. M dying to have 4.2.2..it's awesom.. I am realy realy tired with the current one:(:(
[Galaxy Tab 2 7" Android Development] Skazzy3:
Please use the tar.md5 for now. These ROM's have missing files that are either in hidden.img or cache.img.

My soon to come ROM might fix all of your problems. Since I just did a Odin flash and then pulled it with adb. Not sure tho.

[Galaxy Tab 2 7" Android Development] tobbbie:
Well, I wonder if you can't just test the values for your device yourself? You have all it needs, just get stability tester from the market and start UV you device with system tuner or an other app. Usually you can UV for lower clocks but must OV for higher (than 1GHz). Reserve some safety margin after you found the critical voltage. For UV the sequence is

1. Set upper and lower clock to be the same, start with lowest value.

2. UV for that as you can until the device freezes. Use a tool that does not apply the set values after boot. For higher clocks the device may freeze when setting the clock already, so OV for that clock before you activate it.

3. Reboot with long press of power

4. do less UV or more OV for the same settings

5. Run stability tester for only that clock until satisfied

Repeat above for the clocks you want to check. You may not need all clocks, but just exploit the lowest, regular max (1GHz) and highest with this sequence. Usually you can then interpolate the other voltages depending on clock frequency.

As not all CPU are the same and environment conditions also interfere, there are no safe UV and OC as both are tweaking the limits of YOUR CPU. The only truely safe settings are stock as they comply with the CPU vendor's granted limits.

And after all it is the display that eats most of your power, so keep that at low settings gets you most of your juice.
[Galaxy Tab 2 7" Android Development] iroshan:
Hi dear ketut.

Don't say that. The thanks you get from us (at least from me) are from our hearts. we truly appreciate what you do for our device. Never get discouraged. Even though we are a small group, we care about our developers as we love our tabs. :)

Keep up your work friend.
[Galaxy Tab 2 7" Android Development] Andrev01:
It's true, I fully agree. We like devs that make something cool for us, and your work is great :) But there is always a lot to do, don't get bored with us, we still appreciate your work :)
[Galaxy Tab 2 7" Android Development] tobbbie:
Fully agreed!

Ketut, you are doing a great job here for our tab2 and I am tempted to get dual boot running just to try out another ROM without the usual overhead attached to it. So far the single boot with all the nice OC and UV is enough for my needs though.
[Galaxy Tab 2 7" Android Development] ketut.kumajaya:
CGROUPS, SLUB, and TRACING support back enabled for exFAT compatibility, Android logger disabled by default to compensated it. Performance is important, but compatibility is much more important. That is why currently still trying Samsung S3 4.2.2 vold, fsck.exfat, and mkfs.exfat binaries on CM 10.1, seems works! Settings - Storage works! Still need a final test, but I had to reformat my sdcard to exFAT :( Manually mount exFAT formatted sdcard second partition work without problems :) Anybody want to donate a new sdcard? No way! Even pressing Thanks button always difficult :p Except my old supporter, from Ace era :D You knew who you are ;) But I love my Tab, that's why I love all of the owner :laugh:
[Galaxy Tab 2 7" Android Development] brolee93:

[Galaxy Tab 2 7" Android Development] Dexxmor:
Really great kernel, the one and only for me :good: attached are my current uv settings.

Send from my Blackhawk powered device.
[Galaxy Tab 2 7" Android Development] Andrev01:
You decreased them about 123 - 175 mV. But can I try to decrease them all about 50 mV ? Any value is good, or just some steps or what?
[Galaxy Tab 2 7" Android Development] Dexxmor:
You must find your own setting's, each device is a snowflake. I would recommend that you undervolt in 50 mV Stepps to find a stable setting.

Send from my Blackhawk powered device.
[Galaxy Tab 2 7" Android Development] Andrev01:
Ok, but 50 mV is safe? How to check stabillity? Will device reboot, freeze, or something?
[Galaxy Tab 2 7" Android Development] tobbbie:
How high do you permit your governor to get in reality? Voltages per clock don't tell how high you are stable :)

I also have all voltages but limit clock at 1.42Ghz with 1350mV.

Really not sure how much UV will bring in reality, your device is

either in standby: should be "deep sleep" - CPU not running until wake-lock and your display is off in this state.

or on idle: reading, browsing - but display on, eating most power

or on performance demand: highest clock, relatively most CPU power drain (and this is when you "feel the heat") - but still display ON and still THIS eating most power over all.

intermediate frequencies are not often used, but for all these your display is usually ON.

You can make an art of UV and tweak as much as you like - in the end THIS will not get you much more juice.

To get most from your juice you have to eliminate background hogs by cutting connectivity (either with "WIFI off in Standby" setting or with "Deep Sleep Battery Saver" app) and by sending them to (Linux) hibernate state with "Greenify" app. To observe what your device does, install "Cool Tool" app - the best system monitor around imho. Long term observation is with "BatteryDrain" and for the reasons with "BetterBatteryStats". Armed with those you have all it needs to act. I do the action then finally with "System Tuner" app.

If you want to start scientific observation on the various drains, then read out the (averaged) values available at \sys\class\power_supply\battery\current_avg and observe the values. Non sym-linked path is a little longer: \sys\devices\platform\battery_manager\power_supply\battery\current_avg.

Positive values indicate charging, negative indicate dis-charging.

Mind it is not easy to rule out other influences like charging (should be off), GSM (if you have) BT + WIFI (should be off) and CPU needed to pull the data from that place (you cannot be in deep-sleep).
[Galaxy Tab 2 7" Android Development] Dexxmor:
I don't over clock, for me it's useless. My battery drains (screen of) 0.5-1% per hour (wifi always on)

Hello guys i have a proble i followed all the instruction (i already had latest blackhawk kernel philz recovery so i directly flashed the tool)

so the proble is that i dont se a secondary recovery option in the list so then i dit all the steps again still no hope i did not get the option to hit secondary recovery. i have only one type of recovery and 2 types reboot to android; and reboot to boot loader.

[Galaxy Tab 2 7" Android Development] Caldair:
I would have totally agreed with you, until last weekend, when I upgraded my phone to a Nexus 4. It had totally ruined my enjoyment of my tablet, which previously was by far the best android experience I've had. I now see lag everywhere, though I know it's not even a fair comparison, it is very perceptible at stock 1gHz. So now I too am running at 1.42gHz, with the max UV'ing that my tab can handle and still maintain rock solid stability. Undervolting helps keep the tablet relatively cool (even with my GPU OC'd @ 384mHz) while playing NFS Undercover for hours at a time.

I tend to partially agree with what [MENTION=393455]tobbbie[/MENTION] says above about undervolting; its not going to give you hours of extra screen-on time or anything, so don't expect miracles. But, having said that, I am still of the opinion that every microVolt that can be saved is worth saving. The most important voltages being at your min & max CPU freq, and at your max screen-off freq(for me 800mHz). I could post my specific voltage values, but like [MENTION=4103418]Dexxmor[/MENTION] said ".. each device is a snowflake.. " (:D great way to put it!) so for anyone trying to undervolt you really should experiment and find your optimized voltages. My method was the same as that posted by [MENTION=393455]tobbbie[/MENTION] here.

Finally, [MENTION=4021423]ketut.kumajaya[/MENTION]: Thank you a thousand times for this amazing, peerless work on the Tab 2. I could not ask for more in a kernel, and the dual boot ability is simply phenominal! For myself tinkering around with tabletUI mods on various roms this has made my life SO much easier. No longer do I have to backup my daily rom, flash the rom I'm working on, and then restore again when finished. Now I just flash whatever I want in the secondary slot and I know my primary is there, safe and sound! (Something I got used to on my, now decommissioned Droid3, using [MENTION=4243514]Hashcode[/MENTION]'s SafeStrap) Please, please do not let the lack of feedback or thanks dissuade you from continuing to push the envelope of what is possible on these devices. In my experience it seems like for every 1 click on "Thanks" there are likely 20 happy members using your work. The nature of your work may also somewhat limit your user-base to more of the power users(who should know to hit thanks;)). You can't let yourself get too hung up on thanks here. Just let your achievements be their own reward; and using that scale your reward is massive! It is only thanks to your fantastic customizable kernel that my tablet is able to keep me satisfied compared to a newer device with vastly superior hardware! And, I really don't see a hit on battery life, even using 1.42gHz 24/7.

Thanks again! And please don't stop doing what you do! It won't be much (but certainly what I'd be willing to fork over on the playstore for these features) but I'm going to give your DTM button some of the exercise it surely deserves.

Keep up the great work!:highfive:
