OK,

I have finally fixed my wifi issues manually on my GT-P6810 Wifi only model CM9.

In case some of you don't know not all users can use wifi with this build of CM9.

I have previously attempted to apply the hotfix (see this thread Wifi-hotfix installing the wifi-hotfix.zip from recovery.

I took a look inside the wifi-hotfix.zip file and noticed it was copying a file called wpa_supplicant to /system/bin on my tab.

I then browsed to the \system\bin folder using Root Explorer on my Tab and noticed the files were different byte sizes and file dates. A sure fire indicator they were different.

So setting my file system to read/write on the TAB I extracted and copied the file wpa_supplicant from the Wifi-hotfix.zip to my TAB in /system/bin.

After turning off then on my wifi, it immediately found my wifi and connected. (all this with out a reboot of the TAB)

Sowheat!!

And now the litmus test.

Will it survive a reboot!

It sure does!!

This just posted using my GT-P6810 on my home wifi...

I read in another post DSP manager may have something to do with the audio bug where the sound always reverts back to max volume after switching tracks or playing another video file. One possible solution was to disable all the options in the dsp settings but that has no effect for me. This was really annoying using Google music as I would have to hit volume down after each skip to not have my music blasting out.

My solution was to first check the apps section of settings and clear all data from the dspmanager app then hopefully disable the built in app within CM9. Unfortunately this is not an option but since we are rooted by default with the rom I installed Root File Explorer from the market and removed the apk file from within the system/app folder. I also removed the Apollo apk as I don't use local music playback anymore. Worked like a charm and no more issues with music or video playback. Also no more running dspmanager in the background saving some memory and possibly a bit extra battery life. I don't miss the equalizer or enhancements too much, I'm fine with stock sound and options. Thanks again loccera for this awesome cm9 rom!
[Galaxy Tab 7.7 Android Development] Gilbot:
Thanks, I do like the audio enhancements from DSPmanager tho, but i think I'm going to uninstall it then try installing a different version, maybe not as a system app as well.

All else fails i'll uninstall DSPmanager. Thanks for the heads up.

Well, I played "stupid" and just went with step 4 - but it fixed my problem immediately! Thanks!! :good:
[Galaxy Tab 7.7 Android Development] Gilbot:
Thanks, That DSP manager works perfectly. Not sure about contacts and dialer... def wont do anything in the i815 seeing as how mobile data is disabled.
[Galaxy Tab 7.7 Android Development] aletheus:
mobile data is disabled? as in the GSM radio is on the MB still, and just not active? or it's actually been removed?

@locerra

How can I make a video call?
[Galaxy Tab 7.7 Android Development] Gilbot:
I'm referring to the Verizon variant, GSM version probably works fine? locerra has disabled mobile data in CM9 for now on the SCH-i815. Wifi works. I'm sure LTE/Mobile data will be figured out later.
[Galaxy Tab 7.7 Android Development] admiez:
So the DSP effects work for you all? I thought they didn't work, as for me it makes no difference whether they are enabled or not. Though I'm using the other CM9 ROM which has the same base as this one.
[Galaxy Tab 7.7 Android Development] Gilbot:
Its working with the link Josvaz provided. I had to use root explorer to delete the DSP manager apk that comes with CM9 in system/app. To be safe I fixed permissions and rebooted the tab. Once rebooted, I used root explorer to paste the new DSP manager apk in system/app.

Audio levels and effects work fine now.
[Galaxy Tab 7.7 Android Development] admiez:
I tried doing the same and in other different ways with no luck. Replacing the apk with the one from that package resulted in a constant message saying "DSP had stopped working". It would start happening only after the equalizer presets were visited. The only two effects that seemed to work were the equalizer and room effect.

I tried one last thing by just replacing the system/etc/audio_effects.conf file and leaving the original apk. The compression, equalizer, and audio room effects work with no problem, however bass boost and loudness don't. It's probably just the configuration file what is wrong.

Update:

Actually, bass boost is also working, as for loudness I can't really tell.

just a small question guys, it is safe to change dpi in this rom? the tried to change dpi in the zeta rom and i just got stuck at the boot screen. and if it is ok to change dpi, can i use the dpi changer app?
[Galaxy Tab 7.7 Android Development] tr2ride:
Gilbot, would you mind downloading one of the free GPS test apps and verifying, I'm using the one by chartcross, my tab sees no satellites ever

I can get within 40 feet using wifi based location

I think all google skymap should need is general location then it works off the accelerometers not gps ( guessing )

If you can confirm your i815 sees satellites I'll keep looking for a solution to my issue

Thanks
[Galaxy Tab 7.7 Android Development] mcbooth:
Using DPI changer is what put me in a boot loop too. Manually edit the build.prop with Root Explorer and it will boot up fine
[Galaxy Tab 7.7 Android Development] s28:
May I ask how is this done?
[Galaxy Tab 7.7 Android Development] mcbooth:
Use Root Explorer, browse to /system and find build.prop. Ensure the file system is set to read/write at the top right of the screen. Select edit file. There will be two entries in the build.prop where DPI is set to 160, change them both to the Nexus 7 DPI of 213. Save and exit. Reboot.

If you dont like the result you can always revert the changes.

Warning - I tried this on the stock P6800 ICS firmware with no issues other than a larger screen, I assume the same will happen on the CM9 rom, but make a nandroid backup first in case it does put you in a bootloop.
[Galaxy Tab 7.7 Android Development] sman55:
I tried doing this and it did work. It looked a lot better in regard to the small fonts.......however lots of apps failed including the dialler, so I had to revert back.

Thanks for the info. A dev on the Magnolia rom sk806 (Steve) said to get it to work properly was a very difficult job
[Galaxy Tab 7.7 Android Development] wintermute000:
So you're saying DPI213 works fine on stock ICS but not on CM9?
[Galaxy Tab 7.7 Android Development] mcbooth:
No, i'm saying DPI213 works fine on stock ICS, and that I haven't tried it on CM9 - however I dont see why it wouldnt work.

Also if you try changing the DPI with the app 'DPI Changer' on stock ICS it will cause a bootloop, so you are better off manually changing the DPI in the build.prop on both stock ICS and CM9.
[Galaxy Tab 7.7 Android Development] wintermute000:
thx works fantastic on stock
[Galaxy Tab 7.7 Android Development] locerra:
Ok, back (although won't have much time to work on it for the next couple of days). From reading, it seems like these are the big five bugs that are plaguing the rom:

Wifi wonkiness (I have a network to test this on, but it is a hard issue to fix, and will probably take a good while)

A2DP support (I don't have a device to test this with, so this might take a while, but it shouldn't be too hard to fix)

USB host/dongle support (again, don't have a device to test with)

Camera force closes, especially with video

LPM (charging while off)

I realize that there are other bug reports, but those were the 5 that I saw most frequently or thought were most important.

I815 users: for the moment don't expect CDMA/LTE support or fixes for the autobrightness and GPS. Seeing as the stock release for ICS should be out soon, I don't want to invest a bunch of time working with the HC blobs when we should have ICS blobs soon. There are other issues common to all devices that I want to work on for the moment. Also, I've decided that I'm going to configure the device without phone support, since it was never intended to be a phone.
[Galaxy Tab 7.7 Android Development] rEVOLVE:
aw, booo. :) But but but, it was intended to be a phone as the Int'l version has it, but Verizon just didn't enable it on their version, right? Sorry - not accusing you of copping out or anything, especially since it was never promised in the first place.

Thanks anyway, I guess I should just be happy for what you've given the i815 - esp. when you fix the other issues. sigh. Hoping the i815 ICS comes soon but the way they are at releasing this stuff, I may have moved on to a newer tablet by the time it comes (happened w/ my 1st gen Galaxy Tab, GT Plus).

[Galaxy Tab 7.7 Android Development] locerra:
Yes, but that is not a permanent solution. I will never be able to include that hotfix in the actual rom, and it doesn't work perfectly for all users + networks. Plus there is issues with the MAC address on many (if not all) devices.
[Galaxy Tab 7.7 Android Development] sman55:
This was on a stock ICS (Hongkong) ROM - does work but at a cost - contacts failed, calendar failed and the phone dialler wouldn't come up. I've not tried it on cm9 rom with different dialler. Might try i tonight. The type was so small in text edit when I went to change the settings I had to use a magnifying glass!

By the way, if this rom is developed as a tablet rather than a phone, I assume we can just flash the phone features into it - or not?

Keep up the good work.
[Galaxy Tab 7.7 Android Development] Gilbot:
You're right, GPS is borked. ;p

---------- Post added at 11:43 PM ---------- Previous post was at 11:40 PM ----------

Aw, sucks no phone support, but no biggie. Do you plan on working on mobile data at all tho?

To be honest with you, the remaining bugs or items needing fixes for the i815 are non-issues for me and this tablet has never got so much use out of it, thanks man.
[Galaxy Tab 7.7 Android Development] globiboulga:
Well, that'll be the end of Cyanogen for me then. This is an oversized phone. Use SMS continously with it as well as the dialler on occasion when I can put the tab on speaker... I could probably live without it, but I'd rather have the option...
[Galaxy Tab 7.7 Android Development] locerra:
Not until either an ICS leak or release for the I815. Working with the ICS blobs will be far easier, as that is what I'm working with on the P68x0.

I personally don't see how anyone could consider a device this large a phone -- regardless, it is clear from the design aesthetics that the Verizon variant was not intended to be a phone, while the international variants were designed to allow this possibility. I intend to keep true to the designs of the tablets, the international variants will have phone functionality (assuming I can figure out how to configure it properly for the P6810) and the Verizon variant will have data (in the future), but no phone functionality.

while looking at the kernel resources, can you check for the now popular emmc brick bug? we need to be safe while wiping our tablets and avoid hard bricks. its getting very common now, just check the general section. lots of people are losing their tablets for this brick while wiping.

Kernels with MMC_CAP_ERASE removed from mshci.c should be safe - look for it in the listed features of any kernel

you can read more about the brick bug here
[Galaxy Tab 7.7 Android Development] s28:
another question, though mobile network is working i can't seem to find the option where i can force my tab to use wcmda instead of auto? or where i can force my tab to use 3g instead of auto?
[Galaxy Tab 7.7 Android Development] globiboulga:
I did us the tablet as a phone a couple of times (meaning holding it against my ear) and yes, people starred and I looked like a douche. But that worked. I mostly use the proper phone functions during meetings as a speaker phone since it's way better than my phone (speakers are loud and clear)... But I use the SMS functions daily and it makes loads of sense on a tablet this size (begging for a dedicated client)...

PS: glad to see you still intend to have the functionality available for the international version... Thanks...
[Galaxy Tab 7.7 Android Development] s28:
One more problem I noticed is that photos and music on my sdcard don't show up on my gallery abd play music respectively. Any work arounds? Maybe its because the external card isn't under /sdcard anymore?
[Galaxy Tab 7.7 Android Development] rEVOLVE:
I think a lot of us when we bought the Verizon i815, sort of hoped at some point some awesome Dev here at XDA would be able to free it from the limitations that Verizon placed on it and add the phone functionality that Samsung originally intended for this device.

I would probably use it like the way Galaxy Note users do - with a bluetooth earpiece or one of those little bluetooth handsets. With this capability at least it would have been a nice situation to sometimes just go out with the tablet only and leave my Galaxy S3 at home.

I could -sort of- do this with a SIP provider when the data was working, but because the i815 is missing the bluetooth phone components, the way bluetooth worked was not satisfying because it couldn't handle incoming calls or initiate dialing out from the bluetooth headset/handset.

In actuality THAT is what I desire more is just the bluetooth phone support to be activated so i can use the google voice/grooveIP more reliably with a bluetooth setup. If that can be accomplished without having to turn on phone capability I'd be happy.

What do you think about just adding the bluetooth phone profiles, locerra?
[Galaxy Tab 7.7 Android Development] chrisrotolo:
i think its possible, but you would likely need a new modem.bin either from a similar device or build your own. maybe you could even swap out the modem but not likely.

then theres the verizon network which could be an issue but i expect you could work something out.

would be very difficult but i believe possible, personally i would look into a sim/unlocked variant.
[Galaxy Tab 7.7 Android Development] miiike:
See, there is NOTHING to figure out with the VZ network. If you have a data SIM purchased with the 7.7 and put it into a regular VZW phone it will be able to send/receive SMS messages at a per message cost. Take your SIM out of a phone (with a phone plan) and put it into the 7.7 and 3G/4G work. Hopefully another dev can pick up on locerra's (awesome) work and get us what we're lookin for.
[Galaxy Tab 7.7 Android Development] paranoiadk:
The USB host/dongle mode is working.

I used a free app from Play and later bougth the EzyMount app from "hokikoki", which manages better.

I now auto-mount a NTFS formatted microSD card (in the internal SD card slot) and could mount a 750GB external Seagate drive (with it's own power supply of course), and could see all three partitions on it. Tested it with playing an HD mkv (don't really remember if it was 720p or 1080p) and it worked perfectly.

Almost forgot to mention, I'm using a 3in1 usb adapter I got on DealExtreme for ~5$. It can do with USB, standard SD and micro SD - one at a time.

Quick update:

I have fixed issues 4 (as far as I can tell) and 5. Unfortunately my build system is not cooperating and I have been unable to make a full build, so I'm planning on setting up a linux system to build (I've been stuck on a mac for the past few weeks), at which point I'll make new builds.

I have also done a bit on CWM, and am making new builds for that presently.

Outstanding!

Maybe this isn't the place to ask but when I try to run the music player app "Rockbox" on an i815 with CM9 it works fine except when the main screen is closed (power button pressed). The screen remains closed, completely black and all I can do is force a reboot. Any ideas anyone? Works fine on stock HC and other Android devices with stock ICS.

The app: http://rasher.dk/rockbox/android/

Turn lock screen off on the tablet.

Install the 1280x800 version of Rockbox

Start Rockbox

Press power button to close the display

Press power again to restore the display --> but it doesn't happen.
[Galaxy Tab 7.7 Android Development] rEVOLVE:
just some observations since I've flashed this on my i815:

-since I applied the wifi fix, I've not had any problems and it reconnects to all my regular APs (including my LTE MiFi and when I turn on hotspot on my GS3 ) work just fine.

-I got an Samsung HS3000 to test bluetooth audio via apt-X (besides my Galaxy S3, the GT 7.7 is supposed to support apt-X for higher BT audio quality). I cannot get any audio stream via BT. The HS3000 works great with my Galaxy S3.

-I tried the 30-pin to USB dongle w/ some of the USB keyboards that I used before I flashed this. None of them work anymore.

-There was an issue yesterday where the time displayed on the taskbar got stuck and wouldn't fix itself until i rebooted. Beautiful Widgets clock was fine while the other clock was frozen, but I could interact with everything else in the bar just fine.

Also does anyone know if the INT2EXT+ script from this thread would work with this?
[Galaxy Tab 7.7 Android Development] paranoiadk:
Also, I've tried to connect my Nikon D80 camera yesterday and used "DsrlDashboard" and works great. :) Finally, I can do automated timelapses withoud dragging my laptop around (and I can finally delete the WinXP the software required. :) Although I don't get LiveView, since my camera is too old.

However I can't seem to get any usb keyboard or mouse to work. I don't really need any, but I've tried and had no success.

So the USB host/dongle support gets 4 out of 5 stars. :)

New Builds...

Hey everyone,

I spent the last day working on setting up a new build system so that I could make new builds.

I would like feedback on LPM (offmode charging). Currently I'm using the ASOP icons (which I personally prefer over Samsung's images), but because of how Samsung configured the device, when it is booting into LPM, you will see a brief Samsung icon.

The only way to change this is by messing with the efs partition, which I'm not willing to do in a script (restoring from nandroid backups or even odin images does not revert changes to the efs partition), although I'm perfectly willing do it on my own tab, since I know how to revert the necessary change (just replacing a png with another one). The alternative if this is a huge bother is to use Samsung's charging images -- this is done in pretty much every Samsung device, mainly because of the issue I mentioned (otherwise CM was intending to have the ASOP charger across all devices).

Let me know what you think on the issue: keep them with ASOP images, or change the Samsung battery images?

I personally don't watch my tablet charge cause of much more interesting events in the world. But I haven't minded the Samsung stock images.

Be glad to give my opinion between the choices though. point being whichever you decided should be okay with people, especially, if they don't like it, if they can change it.

[Galaxy Tab 7.7 Android Development] dfkt_:
Hmm, not sure I ever saw the AOSP battery animation, my Tab always reboots when connected to USB or AC. I guess the grey battery with the on/off symbol I see briefly is from Samsung then?

A much bigger aesthetical issue, in my opinion, is that CM9 assumes landscape as default orientation for the tablet, while the Sammy firmware assumes portrait. It might be just me, but I use the thing 90% in portrait mode - not to mention the silver Sammy hardware logo is on the bottom, and everything.

Having the landscape boot animation (after the portrait Sammy logo), landscape upgrade notifications, and the CRT-off animation in landscape is just 'off' looking, in my opinion. I tried to fix that myself, but couldn't. (Of course I changed my boot animation to something else, but that's just the smallest part of the orientation issue.)
