For me it was a bit complicated to install the new market because I didn't want to freeze anything. I wanted to delete the old market completely.

That's how I did it (a bit complicated but it worked 2 times with two fresh rom installations):

- I first made a backup of the original Vending.apk in system/app/ folder (just rename it)

- Replace the Vending.apk with the downloaded apk file (of course first renamed it to Vending.apk and set the correct permissions)

- Tried to start the Market app, which I think ended in a crash of the app.

- Then I clicked the downloaded market apk to install the market properly.

- Tried again to start the market app -> worked

- Restart of tablet -> an error message appears that the market was forced to close

- Then I replaced the Vending.apk in system/app/ folder again with the original backup

- Finally I again klicked the downloaded market apk to re-install the new market app

Then it should work without any error message after reboot and the old market is deleted.

But be sure to make a backup with CWM Recovery before trying this :D. At one attempt I changed the order of the points and then I couldn't make it to delete the old market. Then I had to restore the backup and try again :D
[Galaxy Tab 8.9 Android Development] _motley:
Just to be sure everyone understands...installing this kernel has nothing to do with the version of market you have or don't have. I don't mean to be rude, but this should not be being discussed in this development thread. Let's keep it on topic please. Thx.
[Galaxy Tab 8.9 Android Development] SmittyRN:
True dat... that kinda started a "while we are on the subject" situation. Now, back to the show.
[Galaxy Tab 8.9 Android Development] nirogu325:
Motley, this is my skinned Stock KJ5 ROM with your latest kernel (Dec 4 as of this writing). 99% left after almost 6½ hours untouched with Wi-Fi and AutoSync both ON. This is with: no overclocking, using Interactive governor and undervolting (-75 for 1Ghz and -50 for the rest below 1Ghz).
[Galaxy Tab 8.9 Android Development] jenne1980:
Maybe it's really only a problem with the 3G version of this kernel. Nobody else here with a 7300 who is using Motley's kernel v2d_3G ?
[Galaxy Tab 8.9 Android Development] nuttsan:
Yep, I am (UK based GT-P7300), with Overcome rom, left mine last night for ~10 hours with wifi on, sleep set to "Never", went from 81% to 79% in that time.

Am using SetCPU, overclocking to 1.4, voltages all -50mV, oddly just looked and the scaling is set to "ondemand", whereas I thought I had originally set it to "interactive" when I first set it up, but that was under the previous kernel release...

Edit - Changed to "interactive" and left for an hour and it went from 72% to 71%, i.e. it seems to have dropped a %.

Please note my tests are probably not particularly accurate.

p.s. It might be worth going back to without the kernel in one test and seeing what percentage of the battery usage is used by the "Cell standby" vs "Wi-Fi"...
[Galaxy Tab 8.9 Android Development] rosdol:
mine seems to be ok

Hi _motley,

I also have a 7300, Kernel v2d_3G and OC 2.1.1 and experience no rela batt issues. I have setCPU at min 216, max 1504 no undervolt.

I tested for most of the week, had my tab loaded up on the night sunday/monday and it was running down to ~50% yesterday (tuesday) eveneing - had wifi on all the time, BT was off. The Tab is constantly receiving Push's from exchange and I did some work on it on monday on Tuesday.

Could it be, that it is connected to the Basebband used or does this go with the OC ROM ??

My Radio is P7300XXKHC

[Galaxy Tab 8.9 Android Development] _motley:
Thanks for all the feedback and study on the battery standby. I think we will need to keep researching a bit to better understand what is happening. The power management stuff is the same in both kernels. The only real difference in the kernel build is the modem configuration and then ROM's with enabled data services can use it. I have a WiFi model and don't see anything I would call an issue, but will keep my eyes open for kernel patches etc. that could play a role in better performance in this area.
[Galaxy Tab 8.9 Android Development] telarin:
I am having same issues with this as well. MX Video player H/W mode isnt supported. the player is running in software mode and is laggy when playing 720p MKV file. Is there supposed to be some kind of kernel support issue for the H/W decoding feature in MX video player?
[Galaxy Tab 8.9 Android Development] nirogu325:
Smells like an app device support issue. Try BSPlayer. Some are better than others. I've tried the one you said, VPlayer and BSPlayer and found a little better performance with the latter. Honeycomb H/W decoding in those players is still a work in progress so you won't find a perfect one yet.
[Galaxy Tab 8.9 Android Development] telarin:
I've tried BS player, and it does play smooth, but I like the MX players interface more :D and its ability to resume the movie at where you last watched, instead of at the beginning.
[Galaxy Tab 8.9 Android Development] laser21:
Im on a p7300, I noticed the higher battery use aswell. I left my wifi overnight on, and I got a 11% drop in 10 hours. Im running overnights 211 and motleys 2d3g.

just letting you know!
[Galaxy Tab 8.9 Android Development] nirogu325:
Have you tried the same configuration with a Stock ROM like KJ5? I'm asking this to the 7300 users because the current Overcome version is a GTab 10.1 port and ports tend to have battery issues. We're trying to figure out if it's one or the other or both. Anyone with a 7300 KJ5 running with motley's kernel?

Sent from my SGH-T959.
[Galaxy Tab 8.9 Android Development] jenne1980:
Glad that I'm not the only one with this problem :)

My tests with stock rom + Motley's kernel were with KJ5. Was the same problem as with the Overcome rom as you know. But I didn't test again with KJ6 which I have installed at the moment.

Hope that the new v2e version for ICS doesn't cause this problem as it would make Android 4.0 unusable for me :(
[Galaxy Tab 8.9 Android Development] laser21:
last night I left wifi off, and I got a 1% drop in 10hours. Same conditions as the night before.
[Galaxy Tab 8.9 Android Development] jenne1980:
Jep, the problem is only when wifi is activated.
[Galaxy Tab 8.9 Android Development] _motley:
Thanks for the feedback. Since the wifi and power management drivers are identical in the kernel builds, it got to be somewhere in the stack where networking decides which network to use. The modem driver was not chanceg from stock, just turned on for the 3G build. Still scratching my head to be honest. At least you can try the setting wifi off when screen off. If that works, then that is a half decent workaround I hope. Let me know.
[Galaxy Tab 8.9 Android Development] jenne1980:
I already tested that and it works. Normal battery consumption then. But of course this is no satisfying solution because you can't get mails when the display is off (I'm not using the 3G function).

The only solution for me atm is to use the stock kernel. Everything's workin' fine then. I really really hope that I don't have this problem with your new v2e version for ICS. Maybe I'll test the alpha soon.

Edit:

As posted in the ICS alpha thread, I had exactly the same battery consumption problem with your kernel in the ICS alpha. Of course I made a complete user data wipe and dalvik cache wipe before installing the ICS alpha. And I had not installed any apps besides SetCPU and the Icygapps V2. I set the governour in SetCPU to "interactive" and the max clock speed to 1200 MHz.

Have to wait for the official ICS release :(
[Galaxy Tab 8.9 Android Development] NickFluth:
I am looking to root my 8.9. The one question I have not seen in this ROM is does it have the ability to connect to ahoc wireless tethering? Thanks!
[Galaxy Tab 8.9 Android Development] AshamanMokum:
I'm using joikuspot on my Nokia n8, and i'm able to attach my tab running this kernel...

So yes ad hoc tethering works...
[Galaxy Tab 8.9 Android Development] nirogu325:
You seem a bit lost. This thread's about a kernel not a ROM. Yes it does work as mentioned above. For rooting and more info, refer to my guide in the General section of this forum.

What is CIFS?

Could someone tell me more about this XBOX controller being mentioned in the op post? How is it working? bluetooth? cord?

I hooked up the xbox wireless controller adapter to the usb adapter and the 8.9 tab complained about high power device connected. ( this: http://www.nakedchameleon.com/uploads/computer/P1010143a.jpg ) My guess is, i'm simply doing it wrong.
[Galaxy Tab 8.9 Android Development] Stennan:
CIFS stands for common internet file system. If you have a network drive hooked up to your wifi the hard drive will automount just like a sdcard only bigger (haven't tried it yet)

I have a question regarding the different versions. v2d is the same as v2c with the added bugfixes? it's a bit tricky when devs don't follow the regular 2.1-> 2.2-> 2.3 etc...
[Galaxy Tab 8.9 Android Development] taiger78:
Hello, I have installed (I think :) ) the latest v2d_3G kernel. But how do I check that it actually is installed in the tab? When I check Kernel version it says the same as before (2.6.36.3 root@DELL142#1 SHP PREEMPT Wed Nov 23 17:13:34 KST 2011). did something go wrong?
[Galaxy Tab 8.9 Android Development] jzuijlek:
I've tested mx player and h/w player works. Maybe it's a newer version.
[Galaxy Tab 8.9 Android Development] _motley:
Yes, v2d is the same as v2c with the added fixes or changes. Anything that was changed or fixed between versions will be listed.

That doesn't look like the kernel is installed. The kernel will have "motley" in the name. If you flash a ROM with a kernel after you install this kernel, it will be replaced. Hope this helps.
[Galaxy Tab 8.9 Android Development] Stennan:
_motley, I have a network drive shared via samba. What is the best method to mount the drive so that it is available quickly, i've been using estrong so i know it is possible to go through that route but that would be possible even without the CIFS support.
[Galaxy Tab 8.9 Android Development] taiger78:
Yes you are right it's probably not installed. I tried to install it again and attached is the screen. I get a "Can't access to '/system/csc/NEE/system/'. Does this mean that I do not have root when I boot into Android system recovery?

I have applied root as the instruction from nirogu325 (http://xdaforums.com/showthread.php?t=1406137) And when device have booted I'm pretty sure that I have root access. As all programs that need root does not complain. But is there a possibility that root is not active when device is in Android system recovery mode?
[Galaxy Tab 8.9 Android Development] jenne1980:
I would install clockworkmod recovery first and then install the kernel with cwm recovery.
[Galaxy Tab 8.9 Android Development] taiger78:
That is what I think I have done. Or is the "Overcome_CWM_Recovery_v5.1.2.6_P73xx" not the correct file?

---------- Post added at 02:32 PM ---------- Previous post was at 02:22 PM ----------

Okay got it now, reinstalled "Overcome_CWM_Recovery_v5.1.2.6_P73xx" and now the menu is back. I had that one earlier but it looks like id disappeared when I installed HC 3.2. Thanks for the help ....
[Galaxy Tab 8.9 Android Development] jenne1980:
Jep, when you flash a rom with ODIN, you have to re-install the CWM recovery.

Ive tried this kernel but with it installed, auto rotate will not work. I am permanently stuck in landscape until, magically, it rotates for no reason and I am then stuck in portrait.

Is this a known bug?
[Galaxy Tab 8.9 Android Development] nirogu325:
This previous post sounds very similar. Are you sure you installed the correct version for your GTab? Can you give more details like Android version installed and which model do you have?
[Galaxy Tab 8.9 Android Development] tuck4x4:
Thank you so much, that is it! Im running 3.1 flashing the OC Kernel. As soon as i get home ill flash it again.
[Galaxy Tab 8.9 Android Development] nirogu325:
There are several 3.2 leaks around here for both 3G (7300) and Wi-Fi (7310) models. If I were you, I'd install one of them since this kernel's newer updates are 3.2-only.

what can i do to charge my tab faster, it takes 4 hours to fully charge my tab. TIA
[Galaxy Tab 8.9 Android Development] 0okami:
Hmm... Well, this is about the average time to fully charge mine as well.

Have you tried turning it off while charging? Thats what I do before going to sleep if i have to be up in less than 3 hours. usually its fully charged by then. Give it a shot. I know its somewhat impractical, but if it works for me... might for you.

That aside, make sure you are using the wall charger. 2000mah+ output.

I can confirm issues with 7300(3g) model, using this kernel makes the battery drop about 2 percent/hour, I tried to set wifi policy to disable when the screen was turned off, but wifi never turned off.

Mybattery graph looked the same when screen was on or off, I also noticed that the app I had in foreground when screen turned off, took almost the same percent off battery as the screen, to me it seems like the tab does not go to`sleep` when the screen is off with this kernel.
[Galaxy Tab 8.9 Android Development] jenne1980:
Thank you!! So we are already 3 persons reporting this problem here. Glad that I'm not the only one :) But the option disabling wifi when turning off the screen works on my device. But anyway, that is no solution. With stock rom the device has ~0,25% battery drop in standby with WLan always activated and as long as Motley's kernel can't do that, it is unfortunately unusable for me :( I also felt that the battery drop rate was higher when working with the device (but I'm nut 100% sure about that, could also have been imagination).

@Motley:

Is there any progress regarding this bug? It would be sooooo great to have a working kernel without this bug for the ICS alpha :(

Hi guys. Need your help. I flashed back stock rom but I amusing this kernel. I know I am able to oc and uv but I am not seeing it in both security and voltage control. Am I missing out something? I only see the max scaling is 1000.

Be sure to use the Interactive governor in the SetCPU app. Another tip would be clearing both Cache and Dalvik Cache at the CWM Recovery.

Just check now and then if anything of the governor is changed. If not, try clear the cache and dalvik (like what the above said) and see if that works. :rolleyes:

I would like to give a try to the Motley Kernel and check if the battery drain on my P7300 is as significant as previous testers noticed it (Jenne1980 being the first one who raised this potential issue).

A preliminary question though : I have a Titanium full backup (data and apps) and also a CWM backup, will any of those backups give me a chance to be able to get back to the original Kernel in case the Motley's Kernel is not OK for me ?

In that case, will I have to restore the whole thing from my TB (or CWM) backups or is there any way to restore ONLY the Kernel with no damage to the rest of apps and data ?

In your case, from what I understand from the original post, you would have to:

1. Backup your apps using Titanium Backup

2. ODIN

3. Do a NANDROID backup

4. Flash your preferred ROM

5. Follow this thread's OP instructions regarding the Nandroid backup you did earlier and its importance in restoring the stock 3.1 or 3.2 kernel (depending on what firmware you did Nandroid).

Edit: It would be nice (if possible) if someone can do a Stock Kernel CWM flashable so we can avoid all this trouble if we forgot to do a nandroid backup of the stock kernel.

I don't understand exactly what is the role of the UV.

If my min CPU is set by default to 216000, that should be enough to spare processor consumption during idle periods ... so why the need to undervolt on top of that ?
