Q&A: [ROM-1.2/GRJ90] CM7Tab for the GTab (based on CM7 Nightlies) [Update: 08-15-11] - G Tablet Q&A, Help & Troubleshooting

Q&A: [ROM-1.2/GRJ90] CM7Tab for the GTab (based on CM7 Nightlies) [Update: 08-15-11]
MOD EDIT: THIS IS THE Q&A SECTION FOR [ROM - 1.2] CyanogenMod 7 nightlies for the GTab
ALL Q&A FOR THIS ROM HAPPENS HERE.
Thanks.
---------------------------------------------------
As suggested, I have decided to make my own thread for the Cyanogenmod nightlies and other ROMs. It will make things a lot easier in the long run.
Disclaimer: as with the other Roms, Use at your own risk! Since the CM7 nightlies are basically an ongoing beta, you run the risk to brick your Gtab if you are not careful. Use to learn NxFlash first before attempting to flash ROMS. Also, do yourself a favor and get Titanium Backup! Always backup yours apps/settings and wipe data/cache/dalvik before flashing.
These will be using the bootloader's 1.2 Pershoot's kernel (2.6.32.43 / 1.4 ghz Kernel) for GB. This ROM works with the Gtab and should work with the ZPAD altough I have no confirmation of this yet.
Thanks goes out to: Team Douche/Cyanogenmod Devs for making a great ROM, Zyhong for showing me how to update to 1.2 and a few more tricks, Maxdamage for taking the time to compile the nightlies for 1.1 users, Pershoot for making such a great kernel and Roebeet for being the one that inspired me to take my journey down the Android rom lane.
1) latest version of CM7Tab: CM7Tab build 08082011 (Nightlies changelog)
2) Test CM7Tab with 4950 drivers: Test Build 08152011
Changes in modified version
1- replaced DSPmanager.apk with a previous version that is known to work (7.0.3) (if you open it, it FCs)
2- vold.fstab is setup as sdcard for internal storage & emmc for external card
3- using pershoot's 2.6.32.43 GB kernel for 1.2 bootloader (For more info, check his blog.
4- Read_ahead_kd increased from 128 to 2048.
5- Set up overclocking by default and battery saver script + cpu governors via userinit.sh (from Zyhong's ROM, based on Caulkin's scripts).
6- Replaced Camera libs & apk to stop the 8-bit pixelling.
7- Increased dalvik.vm.heapsize to 64m (07102011)
8- Set some values to improve video playback (07272011)
9- Changed values for lowmemorykiller minfree in init.rc (08072011).
10- changed EMMC to microsd (08072011)
11- updated ROM up to 2.3.5 (08072011)
12- Camera fix (08082011)
To-do list:
1- remove some apks (such as Rom manager) & create a removed apks folder.
--------------------------------
Issues:
1) Once you set up DSPmanager, it force crashes.
1) Vanilla CM7 nightly (only vold.fstab was modified): Latest build: Build 07262011 (Changelog)
If you have suggestions/ideas, do not hesitate to share them.

thank you.

Going to give it a try, tried cm7 a while ago and was great with it but seemed a bit slow. On Iluminate now do I have to flash back to stock?

How long ago did you try it? I try to play areound with CM7 with the CM7tab ROM to see if I can speed it up a little as well. You can give it a try and tell me what you think.

personally I have been using your build for a while and quite happy with it except the market which sometime shows my apps and other time it doesn't. I have not tried any market fixes yet, so it is partiality my fault as well.

I tried it today but was getting a lot of fc's, it did seem a little faster then I remember except the boot up was really slow as I remember. I did not give it a full try because I failed to wipe everything because I was at work and wasn't really supposed to be on it. I will do it again tonight with full wipe and see if it gives better results and let you know.
I just realized you have a tab build so I will try that one. The one thing I noticed right away with cm7 is that my tablet looked like a phone and I have been jumping around from HC roms and got used to a more tablet specific rom. I will give you update in a few hours I think.
Edit: have been trying for a couple of hours now but sent me in to boot loop had nvflash back to stock, will give it another shot once this silly Tap n Tap is finished loading.

Dalingrin was kind enough to provide a fix that seems to resolve most of the problems with market (including buying apps). It was merged in build 07092011+ so give it a try and tell me how it goes.

The FCs you were getting were probbly from DSPManager. It is a known issue that seems to come from a "broken pipe" in one of the libs. For now, it is best just to remove it.
For the bootup, someone suggested moving apps to the SD card. Apparently, it would speed up the process.
I am conscious that 2.3.4 is made with phones in mind but it is a step up from Froyo and having partial hardware acceleration helps.

Just tried again and got stuck on CM7 logo boot loop, this was with the CM7 tab build. did full wipe of cache, dalvik, and user data. Not sure what happened. Restoring to Illuminate rom if you have some ideas on how or what else I can do to try this rom let me know.

Hey there Ice.
First off, awesome work on this and thank you for taking the time.
I would recommend editing the build.prop file to set the Manufacturer to HTC. This fixes the playback issue with Netflix (Chipmunk). I tested this out fully on my gTab last night and it's the ONLY setting that needs to be modified. Aside from that, everything seems to work.
Good work!

Hi
Has anyone tried installing volume+ on this rom? I'm on BL1.1 CM7 rom but volume+ does not install. If this works, I'll take the bold step to upgrade to BL1.2.
I don't know if it's just my hardware. My gtab's speaker is very soft and I want to try cranking it up with volume+ (which works on my phone running cm7).
thanks a lot.

DroidTV phone size not full screen....Anyone have other apps that did that after....
I was using DroidTV, and it was full-screen and then rebuild my G Tab with the cm7tabl-0710200-1.2 and when I reinstalled DroidTV it is now phone size display on the G Tablet.
I used Titanium Backup to restore the app and the settings. Anyone have issues like this with an app that did that after re-installing after a full rebuild? Any build.prop setting or somewhere I could check?
Thanks. Steve.

Thanks everyone for your feedback.
@Mike: I have heard of this before and wasn't sure if anyone would be interested in it. I will change that on the CM7Tab version in the next few days.
@Vhend: Yes, Vol+ works on 1.2. You enter CWM and it works great here.
@Artful: I will look into this. It might just be that the rsolution isnÈt set right. I will let you know how it goes.

Thanks Ice. Other than that I have yet to find any major issues that in the build.
Other than apps that open portrait only with the bottom on the side with the power button. Tried to say to not rotate 90 degrees but they still open that way Apps that open landscape then won't rotate to the 90 degree position but portrait apps still open that way
This is the most stable I have used and performance seems good. A co-workers has the same build, I installed it for them since they are techie-challenged, and theirs is turtle slow because I think they have Skype running all the time.

sorry for not being clear. I did not mean pressing the volume+ button. i actually meant this app to boost the volume of gtablet.
http://forum.xda-developers.com/showthread.php?t=1023433
I guess the app has dependencies on dsp manager, that's why it did not work on my B1.1 cm7. Since you have replaced the dsp with a workable one in your rom, I would like to check if the volume+ app works here.
Appreciate your work on the rom!

Actually, I think it has more to do with a problem with one of the audio libraries. I did a logcat and it seems something called AudioFlinger can't set a parameter properly.
If anyone can fix this, I can send the logcat to help out.

I wanted to apologize for not being able to upload the new nightly today. I had to rebuild my computer and took the opportunity to switch to a new Linux distro. Just tested the new system and all is great.
I will post Build 07172011 later this morning.

---

Where are the nightly's getting posted now? Thanks and this is the most stable MOD I've had on my G Tab.

---

Do video apps work as far as no rotation with Oovoo, yahoo, reelportal, etc? Audio work okay with chatting?
