Came across this article about sysctl tweaks and it seemed like it could be something cool to look into. I was just wondering of this is something that could be done to help tweak out our Revo's, even though BO 1.1 already has them tweaked out pretty nicely. Thanks a bunch MT!!!
So does anyone know if this is even worth looking into?
From the brief read I had it seems like it just controls how stuff is done and tries to optimize everything so it's very little. Could be useful possibly.
I installed this and the script it installs in init.d is there and runs. We shall see how it goes

Hi
I've been having a look at the firmware files released by NI to fix the update blunder they had.
From a quick overview the following nice things appear to be true:
* NI is using test-keys to sign everything which means there's no security really
* /xbin/su is present. I'm not sure if this means you can just adb shell and type /xbin/su to get root (since I don't have an adam yet)
* The boot image is standard format. It appears you can just unpack/repack with secure set to off (making sure that offsets etc are correct!)
Based on this, rooting this thing should be piece of cake..Just repack boot.img and flash..Getting a custom recovery probably requires a bit more to make sure the LCD/PQI actually works in recovery?
Great work so far Rayman. I posted over on this thread in an attempt to get some Adam users to come over to XDA and lend their tablets. http://www.notioninkhacks.com/forums/viewtopic.php?f=29&t=227&p=2406#p2406
It would be nice if we could minimize the duplication of efforts and get this thing rooted and unlocked.
Agreed. Thanks rayman. The gtablet folks are already messing with Eden and the Adam Rom, I can't wait until some more people get their Adams and hacking starts. I'm not so sure that notion ink's idea of what we would like in a Rom is actually right. I will be checking the xda dev section often.

Did you see the Eden Plus thread by Rothnic? Looks like he's got it rooted and the stock Google Apps added.
My own observations (and I could be totaly off base)
I have yet to hear of a successful update.zip, so I'm wondering if their recovery is borked, right now.
Look at their LCD.zip. It's an nvflash format, and yet there's still some remnants of an update.zip, namely the command file. My guess (and it's only a guess) is that they were initially going to create the fix using recovery, and then switched over to nvflash later.
Has anyone managed to get an update.zip working, yet? Man, I wish I had an Adam just to punch this through and get it fixed - I hate sitting on the sidelines like this.
I have my adam, got it yesterday, and would be willing to test for devs. I have rooted it and have the market and adw on it now. I have decent knowledge of android, using adb, recovery, flashing roms and mods.

Sorry to be off topic but. Here is the question: those of u who own a Adam, is all it was cracked up to be or just like a Gtab by veiwsonic, that might have Ben rushed into production? I'm not looking for fanboy type of answers but good, well informed, educated answers.

I believe it is a great tablet. All the apps and games run great on it. The resolution is amazing. The Eden ui is a little glitchy but adw runs amazingly fast. I haven't had any issues with it yet and I am a long time android user

Sounds promising as I am waiting for mine to ship. I heard Eden is very beta quality. I would actually prefer it wasn't there at all. Looking forward to the Honeycomb update. All the new honeycomb tablets coming out at $800+ certainly makes the Adam look like a steal once it gets Honeycomb.
what is fugu? i hear about this in firefly 7.0 and did a google. i got something like... Fugu is a graphical frontend to the commandline Secure File Transfer application (SFTP). what exactly is this and its benefits?
after doing a google search i got this thread that says, "This tweak adds responsiveness on the phone" on the fugutweak thread here:
http://forum.xda-developers.com/showthread.php?t=981125
Been running it for awhile now and the biggest improvement I see is the screen sensitivity. I can barely brush my finger across the screen and it switches homescreens. Pretty nifty, no complaints yet.
I am running pheonix 7 with paragon 1300 uv and occur. Ir is smooth as butter. The figure is noticeable when you scroll and flip through screens. I am a fan.

Big fan here also. I'm running Firefly 2.5 and the screen response is like lightning! I just THOUGHT about opening the XDA app and it popped up! OK maybe not, but the screen feels like its been greased. No lie.
^ That was funny... lol
I assumed this would be in the right place since this would take some tweaking of the guts. Aside from throwing on a custom rom (since we have none yet) what can I do to make this phone run even faster?
I like using LauncherPro found in the market, seems to drastically improve the performance of the homescreens.
I'm using Go launcher. I liked LP+ but invariably it seemed to eventually stop running correctly after awhile. GL hasn't done that. Thanks though
I have some tweaks I will post AFTER we get a working backup solution. Not my work...but worked on my phone. I had one person out of a handful say it boot looped the phone so better safe than sorry

I always use SPB Shell 3D. For4 what it does and how badass it looks it uses very little resources. If I could figure out how to upload my screenshots I would show you what it looks like.
well i was using nemus but cant tweak it the way i want with the themes... so i tried iLauncher which mimics the ios and it was running really smoothly untill i changed dpi and had 2 reflash... now im giving a 2nd shot to GL
THIS IS NOT MY WORK, PLEASE THANK THE OP

Hey everyone,
So, I was experiencing significant lag as we all do from time to time, and decided I was going to get to the bottom of it.
After tracing and debugging for hours, I discovered the source of 90% of Android's lag. In a word, entropy (or lack thereof).
Google's JVM, like Sun's, reads from /dev/random. For all random data. Yes, the /dev/random that uses a very limited entropy pool.
Random data is used for all kinds of stuff.. UUID generation, session keys, SSL.. when we run out of entropy, the process blocks. That manifests itself as lag. The process cannot continue until the kernel generates more high quality random data.
So, I cross-compiled rngd, and used it to feed /dev/urandom into /dev/random at 1 second intervals.
Result? I have never used an Android device this fast. :good:
It is literally five times faster in many cases. Chrome, maps, and other heavy applications load in about 1/2 a second, and map tiles populate as fast as I can scroll. Task switching is instantaneous. You know how sometimes when you hit the home button, it takes 5-10 seconds for the home screen to repopulate? Yeah. Blocking on read of /dev/random. Problem solved. But don't take my word for it .. give it a shot!
Update!
I've built a very simple Android app that bundles the binary, and starts/stops the service (on boot if selected). I'll be adding more instrumentation, but for now, give it a shot! This APK does not modify /system in any way, so should be perfectly safe.
This is my first userspace Android app, so bear with me!
Note that this APK is actually compatible with all Android versions, and all (armel) devices. It's not at all specific to the Captivate Glide.
Caveats
There is a (theoretical) security risk, in that seeding /dev/random with /dev/urandom decreases the quality of the random data. In practice, the odds of this being cryptographically exploited are far lower than the odds of someone attacking the OS itself (a much simpler challenge).
This may adversely affect battery life, since it wakes every second. It does not hold a wakelock, so it shouldn't have a big impact, but let me know if you think it's causing problems. I can add a blocking read to the code so that it only executes while the screen is on. On the other hand, many of us attribute lag to lacking CPU power. Since this hack eliminates almost all lag, there is less of a need to overclock, potentially reducing battery consumption.
If you try it, let me know how it goes.
ROM builders - feel free to integrate this into your ROMs (either the .apk / application, or just the rngd binary called from init.d)!
If anyone's interested, I've launched a paid app on the Play store for non-xda users. As I add features I'll post the new versions here as a thanks to you guys (and xda community at large for being such a great resource). But if anyone's interested in the market's auto-update feature, just thought I'd mention it.
Cheers! :highfive:

Just wanted to share this with anyone who hasn't found it through the portal or general thread popularity yet, the original thread can be found here.
As you can see, this .apk (it's easiest to download it from the original thread which has a QR code) claims to increase speed and fluidity in any ROM on any device. Having installed the .apk and set it up correctly, I don't see any significant difference whatsoever. The phone feels marginally faster but I'm almost certain this is just a placebo in my case. HOWEVER, I am very clearly in the minority here as there have been 499 posts in that thread almost all of which are praising the OP, so you should definitely try this out. There are no downsides to it and it doesn't even involve flashing. Just download and install an .apk and turn the thing on and all should work.
Please post any results with as much information as possible here too, it may be down to NexusHD2 JB

just installed it and like you see no difference yet,,so will wait a couple days
and see if anything changes
Cheers for the feedback, having now used it for slightly longer I still see no change. The thing is, there are so many positive reports that I don't think this is just a placebo, but it unfortunately doesn't work on our device.

yea its garbage no difference at all been messing with my phone all day and
still have lags
it may work on other phones but it does not work on our HD2s
uninstalled it
Wow. I didn't believe it at first, but it's for real.
I heard about an app that someone on XDA released that helps generate random numbers for /dev/random. The theory was that the phone was blocking all over the place while trying to generate random numbers for various processes. This would slow things down considerably.
The app creates random numbers and feeds them to /dev/random every second so the applications don't have to block. It's unreal how much difference this made instantly.
Here's the thread with the explanation and download!

Wow it really works...

I just did a whack of reading on this topic... There's a huge fire fight going on at google code as to whether or not this actually works the way it says it does... Many say yes, many say no. Either way, it sure does cut down the lag. Personally, I don't care how it works as long as it's not eating battery to do it.
I've had my phone on the charger all day. If I can still get my 24 hours on battery with this app, I'll be a happy man. I will also try integrating it into CM10 so you we can have a flashable add-on for CM10 based ROMS, with no need to have the app installed.
