Here's what I did to get CM7 working, coming from Overcome and using CWM to flash:

Let's assume you have a Overcome 2.0.0 Gold, working, with the Overcome ClockWork Recovery, the one with blue lines. (very important)

Make a backup of your current rom.

Download the CM7 for CWM, put it in the internal memory card.

Download the 3.0.0 Kernel from Overcome here (informations here) and put it on your

EXTERNAL SDCard

Reboot into recovery.

Wipe everything

Install Zip from Internal SDCard, choose CM7

Reboot.

And it's working !

If you want to reinstall your Overcome:

Restore backup you made before installing CM7

Flash the Kernel 3.0.0 you downloaded on your external SDCard (because the CWM Recovery from CM7 doesn't see the Internal SDCard)

Reboot

I hope it will work for you.

I don't understand why flashing the kernel also flash the recovery partition on my gtab. I own a G2 and when I flash the kernel, it doesn't alter the recovery partition, if someone could explain this... could be cool :-) Thx !
[Galaxy Tab  Android Development] pendevous:
I opted for Heimdall. However, I didn't factory reset my tab. Now my apps are acting all weird. -_-;

Edit: Working fine and smooth. :) Thanks all.

Edit2: Spoke too soon. I can't play avi files. O_O

Anyone tried Netflix yet?
[Galaxy Tab  Android Development] wallah:
thanks

Hello,

i flash the new update and all works fine !!! just one question, how i can use the internal storage ?? when i mount the usb i can use only external sd.

Thanks for the hard work and to give us the new rom for our Tab !!!

I can't do the donation but i very, very grateful for your work and all the dev !!!!
[Galaxy Tab  Android Development] af974:
Because in Gtab the recovery is inserted in Kernel (zImage)....i know, that's sucks lol.
[Galaxy Tab  Android Development] pendevous:
My Titanium backup seems to not work. I can't batch nor restore even when I downloaded the new busybox. :S
[Galaxy Tab  Android Development] af974:
When i mount it with pc i can see both internal and external sd card, what's your detailed problem?

Are you able to see your folder backup in Titanium B. ?

In CM7 sdcard is the removable sd not internal.
[Galaxy Tab  Android Development] pendevous:
Nope. How do I set it to detect mmc instead, because that's where my internal backup is?
[Galaxy Tab  Android Development] af974:
You can copy your Titanium folder from internal to external.

You can use Titanium backup setting to let it see external sd.

Or you can extract attached file to /system/etc with rootexplore or adb and you will have your internal sdcard as primary card.
[Galaxy Tab  Android Development] pendevous:
My Tab can't be detected by my laptop though. :S

And There aren't any settings in Titanium Backup to let is see external SD. O_O

And I have no external SD so...
[Galaxy Tab  Android Development] wallah:
Thanks you,

yes i see only my sd card 16giga, but not the internal storage, and i can't not copy the movies.... :o

EDIT !!!!! Forget my question, im just reboot and after that i just mount the usb, now i can see internal and external storage !!!

Thank you !!!!!!!!!!!!!!!!!
[Galaxy Tab  Android Development] af974:
You Laptop cannot recognize your Tab because you did use heimdall for flashing thi firmware.

Install those drivers http://www.multiupload.com/RYT34OMSEJ and you will be fine with that.

As for Titanium backup, extract the vold.rar to system/etc and you SDcard will be the internal again.
[Galaxy Tab  Android Development] Technomancer:
Doesn't work, starts playback and returns to queue screen.
[Galaxy Tab  Android Development] maxtcee:
Netflix works just need to install adobe air and reboot

HBO go also works but has some video complications and freezes now then
[Galaxy Tab  Android Development] pendevous:
Replaced the void.stab in the systems/etc and restarted my Tab. Didn't make any difference though. :(
[Galaxy Tab  Android Development] af974:
Uhm....go to setting/memory and check Sd card what say.

Mine works fine with that vold, sdcard is my internal and emmc is my esternal.

What did you use for copying it into tab? You need a rooting file explore or adb, normal file explore doesn't work.
[Galaxy Tab  Android Development] Technomancer:
Update, kernel changes

Update:

2011-06-05

Added 10-point Multitouch to kernel (thanks to The_Double and hoss_n2)

Added overclock (1.4GHz) and undevolt (thanks to Richard Trip and Koxudaxi)

Added Voodoo Sound V9 (thanks to Supercurio and Richard Trip)

Switched to (some) Crespo EGL SOs, hopefully will fix some OpenGL issues.

Hey folks,

So here is another update. A bit of kernel goodies. And OpenGL libs from Crespo. Please test your OpenGL apps/games and see if anything is better/worse.
[Galaxy Tab  Android Development] maxtcee:
Great downloading now

side note can you put on the updated zips got so many hard to tell which is which
[Galaxy Tab  Android Development] dan13l:
Anyone had any joy getting CWM to work for backups? I get told the sdcard can't be mounted. I've added the vold file so the volumes are switched within the OS (working fine), but CWM seems to ignore that. I tried mounting the emmc volume from CWM too, but it seems to be hard coded to back up to SD.

Any ideas?

Edit: worth pointing out I don't have a card inserted, otherwise it'd be less of an issue. Maybe I should just buy a card...
[Galaxy Tab  Android Development] TheGrammarFreak:
Backups work fine for me. Changing the vold in recovery is a bit tricky, I think you'll need to pull the zImage apart to do it. Hex editing FTW ;)
[Galaxy Tab  Android Development] dan13l:
Have you got an SD installed? Thinking maybe that's the way to go.
[Galaxy Tab  Android Development] Technomancer:
There are two zips linked from the first post. Is it too many?

Yes, you should have SD card inserted if you want to backup to sdcard.
[Galaxy Tab  Android Development] pendevous:
File Expert with root explorer option on. :S

Edit: Tried with the normal Root Explorer. Worked. I spent money, but it's worth it. Thanks a lot, man! :D
[Galaxy Tab  Android Development] TheGrammarFreak:
Of course ;)

@Tech: the zip issue is that all version of the ROM have the same name in the zip. It's not a problem for me, I delete old zips as I go anyway. Just to clarify though ;)

Also, the new version is cool. NOVA still doesn't work for me, I still get a white screen. And fitting 10 fingers on that screen is absurd. Lol :D Chrz dude
[Galaxy Tab  Android Development] YoMarK:
Great job Technomancer, CM7 on the tab is getting better and better.
[Galaxy Tab  Android Development] grukko:
Was wondering if someone can explain how to get the stock gb browser working in this rom. The version that comes with it is not as smooth and reminds me of the stock froyo browser. Aside from that this rom is awesome!
[Galaxy Tab  Android Development] wackymix:
Stupid question here, but what has CM7 Gingerbread better then Gingerbread stock rom ?
[Galaxy Tab  Android Development] af974:
I ususally don't play games with my tab but in quadrant, with latest version , there is an improvement in 2D graphic fps but 3D is worse then before.(690 against 790)

Thanks for new version though.
[Galaxy Tab  Android Development] iamloco:
there's a lot of customization and optimisation like

- profile that let you disable some setting for notification , network etc

- tweaked powerbar (those icon when you drop the notification bar)

- no samsung/carrier system apps that no one use anyway

- no TouchWiz

- quicker update and support event after Samsung pull the plug on their device.
[Galaxy Tab  Android Development] paulshields:
Overclocking the kernel seems to be working ok with new build. Running fine at 1400MHz. Definitely a noticeable performance boost. Did need to reinstall Flash do get iPlayer working properly. Not sure if that's related to the upgrade.

Also I tried a nandroid restore from recovery and noted that it hung when creating .android_secure - may be similar reasons to the previous issue when hanging in install?
[Galaxy Tab  Android Development] TheGrammarFreak:
3D gaming is definitely slower now :(

Also, setCPU shows the CPU going to 1.2GHz, despite it being set at 1GHz...
[Galaxy Tab  Android Development] razibhasan:
Just installed the new update. Quadrant score is 3033 :D. It's amazing and blazing fast. Keep up the good work :-).
[Galaxy Tab  Android Development] grukko:
Sorry to keep posting this question but can someone explain why the browser that comes with this rom is so slow/choppy? I really want to continue using cm7 but the choppy performance of the browser compared to stock is frustrating since I mainly use the tab to surf the web.
[Galaxy Tab  Android Development] -Howard-:
my browser is lightning fast no problems and it is faster than the stock Samsung one for me. So im unsure of why yours is so choppy and mine is smooth :confused:
[Galaxy Tab  Android Development] grukko:
Hmm that's strange. Maybe it's the way I'm going about installing this rom. I used the gb stock safe rom from overcome, then installed the tcm7beta files using heimdall, then flashed the update with cwm.

Going to try using the original stock rom from chainfire.

Do I need to use heimdall at all or can I just flash the update after installing the stock rom?

Thanks!
[Galaxy Tab  Android Development] Jeffro64:
I think he was asking if you could add build numbers to the zips like they do on the nightly roms. :cool: I gotta download and try this new one soon as I get back today!
[Galaxy Tab  Android Development] TheGrammarFreak:
It's fast here too. Post a logcat, there might be something running amok

The way you install it is somewhat arbitrary, and a restock won't help. Just do a full wipe from recovery (format /system too) and re-flash the zip
[Galaxy Tab  Android Development] Technomancer:
No, it should be flashed with Heimdall (or you can repackage it in tar file for Odin).

I'd rather flash via Heimdall or **** with redbend and CWM which is a mess.

As long as you don't flash bootloaders you can't brick your Tab with Heimdall.
[Galaxy Tab  Android Development] Landroid:
Didnt work :(
[Galaxy Tab  Android Development] GANJDROID:
Thanks for the answers :)

I'm new to the Samsung flashing ways, more used to downloading roms and flashing from Rom Manager.

Is the CM7 zip the only file needed for Heimdall?

[Galaxy Tab  Android Development] julianLo:
the flashe just contains the command line for heimdall. It's not needed if your using the heimdall gui.

Problem with applying zip file updates in recovery

I flashed the CM7 beta on my T-Mobile Galaxy Tab and it comes up and works. When I try to update the google app zip file in recovery it gives many errors. It seems to have CWM 3.0.

Even booting into recovery gives a lot of errors about mounting. It is not mounting:

system

sdcard

and a whole lot of others

But booting the system in normal mode seems to work. Both internal and external sd cards seem to be mounted in proper places:

/mnt/emmc

/mnt/sdcard

But there are no linked folders in the root directory for emmc and sdcard. Additionally, accessing the sdcards using the USB connection does not seem to work either from the booted system.
[Galaxy Tab  Android Development] Technomancer:
/sdcard link is supposed to be removed in Gingerbread.

I know recovery is hosed. No need to post about it anymore.

I haven't looked into vold/usb mounting issues yet.
[Galaxy Tab  Android Development] julianLo:
regarding bluetooth:

did you try restarting the service:

# adb shell stop hciattach

I could start bluetooth, but since I somehow lost the charger for my BT headset, I couldn't test it any further.
[Galaxy Tab  Android Development] vinclar:
8 MIXER 0 0 0 1 rw ENUM FM Radio Path { FMR_OFF=0, FMR_SPK=1, FMR_HP=2, FMR_SPK_MIX=3, FMR_HP_MIX=4, FMR_DUAL_MIX=5 }

Do you think is posible to enable FM Radio? I mean its hardware capable and the software resources are avaiable?

This belongs to kernel development or full rom development? Thanks for your time.
[Galaxy Tab  Android Development] Technomancer:
I think radio needs to be fixed in the kernel. I don't have source for radio module.

Eventually I will try to fix it, but there are more important things not working at this time.

@ayman07 please read the readme.txt file. adb shell and stop hciattach and try enabling bluetooth again.
[Galaxy Tab  Android Development] TAMIM2007:
Great work.

I am excited to experience.

Please explain the development of easy to install.

Thanks :)
[Galaxy Tab  Android Development] Technomancer:
bump, new release, zipfile has been updated

2011-02-03 New kernel from Update1

Refreshed repo and rebuild with latest

added codeworkx's brcm_patchram_plus fix that should hopefully fix bluetooth initialization

PS. also gapps have been integrated so stop *****ing already ;-)

I suggest clear /data, /cache and /dbdata before flashing.

edit the file: vendor/cyanogen/products/AndroidProducts.mk

remove the system/device/samsung/crespo directory.

then it should work.

Hey tech

Is it possible for you to jump our framerate up past its current 60 limitation?

I will look for some links, but i know other devices (gtab?) have achieved 70 and 80. This will make all video and games blow our mind!
[Galaxy Tab  Android Development] Useless_Alias:
This rom is smokin' with the new kernel, 3600+ quadrant, vast improvement over the previous release. Nice work! I haven't seen it anywhere and no one answered me few pages back, does this rom support TV-Out, if not will it in the future possibly?
[Galaxy Tab  Android Development] OrionBG:
1+ on this! Any news about the BT Handfree profile problems with sound?
[Galaxy Tab  Android Development] Jeffro64:
Has anyone flashed the CWM zip over a Heimdall install? I ask because I had everything working well before trying to do a update and I got stuck at the Samsung screen and it wouldn't let me wipe and flash again. I would wipe and go to flash the zip and it would error out. Just want to check and see if anyone had luck that way... if not do I only need the zimage and the factoryfs.ext4 to update with Heimdall?
[Galaxy Tab  Android Development] af974:
I did it but since i was coming to another firmware, i did it stock before.

Anyway yes, only factoryrs and zimage is what you need.
[Galaxy Tab  Android Development] Jeffro64:
Kewl thanks! I'll just load up Heimdall then... seems a lot easier anyway now that i've used it.
[Galaxy Tab  Android Development] jeremysv:
I just tried Netflix on the latest build and was able to resume a movie with no problem.
[Galaxy Tab  Android Development] maxtcee:
Anybody got a basic oc/uv settings everyone I try puts me in a freeze

I know its trial and error just want a starting point
[Galaxy Tab  Android Development] TheGrammarFreak:
I did. Installed CM7 via heimdall before the CWM version, and I've used the CWM version since. No wipe ;)

I have no OC, but -125mV across the board. Works fine like that on higher frequencies too :D
[Galaxy Tab  Android Development] paulshields:
I just set the max to 1400 in setCPU and it's been very stable so far. I have set up other profiles to reduce clockspeed when screen is off etc, but most of the time it's running flat out. System panel not showing any overheating or big battery life issues. The tab is very fast now.
[Galaxy Tab  Android Development] TheGrammarFreak:
@Tech, how complete does this have to be before you can/will push this upstream?
[Galaxy Tab  Android Development] Jeffro64:
Good to know... Maybe i'll try the CWM again next time.:cool:
[Galaxy Tab  Android Development] nobleskill:
@tech

Mate unbelievable!!!! It is very smooth, seems stable enough and the tablet tweaks!! Wow.

So I note a few post about quadrant scores of 3600 so I guess I'm not the only one with no x264 hardware acceleration!! Lol. Obviously making the changes in blade buddy made no difference and I noted that in the build.prop there is no reference to hardware acceleration. Prolly over simplifying but can I just add the required lines in? I guess the question is does the libs from the other setup used support hardware acceleration for x264/acc ect?

Why, you ask? Well I get 720p avi and 1080p mkv animation (16gb class10 SD) and use my tab to watch them alot. I must have misunderstood the first post about it working.. on an interesting note 1080p x264 mp4 works fine so maybe its an easy fix to unlock mkv? Im not sure why 720p avi is broken... tbh im not really even sure what codex they are base?

Really happy to experiment if you send me on the right path cause I don't think I can give up my cm7 now, its pretty!! But I need me videos!!. ;-)

Sent from my GT-P1000
[Galaxy Tab  Android Development] paulshields:
Yeah, HW acceleration is definitely a big thing to get on this rom. Or at least, HW accel for all video types. I can play some 1080p high profile mp4 files without any slowdown so I'm sure there is some acceleration going on, but it's like it's not there for all codecs. Samsung has DivX licensing on this device - not sure if that can be carried over into this rom? The Tab can certainly blow away current Tegra dual core tablets in stock form when playing HD material. Would love that to be possible here :).
[Galaxy Tab  Android Development] grukko:
Hi grammarfreak. Finally got around to reflashing everything. This time I used the stock gb rom from chainfire. Installed the archive factoryfs and zimage with heimdall, factory wipe and formatted /system, then flashed the 6/5 update. Browser is still the same. As far as I know, I'm doing everything pretty much correctly.

I've included a video of a comparison of the stock browser vs. the cm7 browser. The stock is on top. It's perfectly smooth while the cm7 one is choppy. Can you compare with your browser?

[YOUTUBE]6igopuKKDeg[/YOUTUBE]

Btw, logcat didn't show anything suspicious.
[Galaxy Tab  Android Development] TheGrammarFreak:
Oh wow, mine's about the same actually. I'd just never seen anything better on the Tab. Lol. I wonder what Sammy did to make it work so smoothly?
[Galaxy Tab  Android Development] af974:
Hardware accellerated?

In fact, it's not only browser that is a lill choppy but overall scrolling is.
[Galaxy Tab  Android Development] nobleskill:
Yeah. So a a little early morning experiment has established for me that with the right player I can get the 720p avi running smooth, I can get the 1080p mkv with terrible frame rate but anything more than a SD avi through the core player fails. I like rock player for testing these days, its good to be able to specify hardware/software decoding.

Having 720p avi is kinda good enough for me I think. Its the lions share of my videos and looks sweet on the tab. Would it use more battery though? It would have to as it's using the CPU a lot more than if done through GPU I'm guessing.. and it would be nice to be able to show off to the lads with the 1080p mkv back! Anyways, very busy day today so will check back periodically but if I'm honest with myself, there won't be time for sitting round watching view on my tab today!!

The tvoutserver and associated libraries are there. I don't know if they do anything useful though. You can try and let us know.
[Galaxy Tab  Android Development] grukko:
Hehe. Atleast now we're on the same page ;)

Maybe technomancer can take a look into this? Hopefully it's something that can be carried over from stock.
[Galaxy Tab  Android Development] TheGrammarFreak:
Yes. @Tech, you reckon it could be "fixed". Or is it beyond the scope of what you want to do here?
[Galaxy Tab  Android Development] nobleskill:
Yeah I think its related to what I'm looking at. Dolphin seems smooth though and tbh I never use the stock browser but its still nice to know it works.

As soon as I'm sure I've got the ability to live without my phone I'm going to start tampering with the build.prop and add in the required lines. Hope for the best plan for the worst and I really need my phone for atleast the first couple of hours this morning...

Is it just me or is typing about a Million times faster and accurate? I use thumb keyboard and its going like the blazes.... faster than a real keyboard now I think.. love that!!

I stopped using dolphin after the official gb rom came out. As smooth as dolphin is, it cannot compare to the speed of the stock browser. As someone who also uses an ipad 2, I can say the the performance is comparable to safari.
[Galaxy Tab  Android Development] Technomancer:
I don't know, but it needs to be very clean, minimal changes to framework and other libraries besides device_samsung_galaxytab. Everything should be working and I am not sure about whether they accept binary drivers in vendor/samsung/GT-P1000.

I have noticed that SetCPU sometimes shows 1.2GHz for short time even though max is set to 1GHz. I ran Quadrand and polled /sys/devices/system/cpu/cpu0/cpufreq/cpuinfo_cur_freq in adb at the same time and it was showing 1000 most of the time, sometimes 800. So maybe something is weird with SetCPU?

Everyone: How you install it (Heimdall or CWM) doesn't change how the ROM works. Either way is OK.
[Galaxy Tab  Android Development] Useless_Alias:
Hope to have my cable in a day or so, will provide results.
[Galaxy Tab  Android Development] TheGrammarFreak:
CPU Spy shows that 1200MHz is in use, and that my Tab has been using that frequency. Also, the frequencies don't show up in CM's built in CPU control (CMSettings --> Performance)
[Galaxy Tab  Android Development] Technomancer:
We have the same browser as everyone else in CM7 has. "Fixing" it is frankly beyond my abilities and interest. I am not going to fork the browser and try to fixit just for the Tab. It should be fixed upstream (in main CM7 repo) by people who know what they are doing. The problem with the browser is kind of unclear and "smoothness" is not very quantifiable.
[Galaxy Tab  Android Development] Technomancer:
That I know and maybe can fix.

Hmm CPU Spy shows 43 seconds total in 1.2GHz state for the last night. So it appears it somehow goes to 1.2GHz, but never to 1.4. Maybe something weird with the governor?
[Galaxy Tab  Android Development] TheGrammarFreak:
I thought as much. I did a bit a of Googling and it looks to be a nightmare to do anyway.
