Hey all, I'm a lurking noob here. First android phone, but lots of previous linux experience. I rooted my phone, loved it, installed the 1-click ext2 lagfix, loved it more. Then, got itchy, formatted the phone to JH2, and re-rooted using unleash the beast. Still love it!
However, I'm wondering if there's a way that I can tell if that ext2 partition is still there? I think that reflashing a stock rom through odin would remove it, but I'm not sure.
I'm bumping this in case there's someone who can answer my question on this evening. The lag fix itself is clearly not working, since my quadrant scores are normal (~900), but I don't know how to check to see if the ext partition is still there.
use the following apps: dolphin HD browser, twitter, facebook, k-9 email, touchdown, feedr
if any of these are laggy, there is no speed fix applied. Dolphin is near unusable without a speed fix.
hi all
i followed the disskusion in Milestone XT720 Android Development CyanogenMod 7.1.0 Milestone XT720 RC1
tried 2 reply but i never posted something so iam not allowed to post in def forum
i think iam not the only one with this problem
tried to make my 10 post in offtopic to join the diskussion but faster deleted than posted
so here i go
at first i wanna thank all the devs for the good work
to see cm7 build from source on my xt720 makes me smile
although thanks to all other guys made roms 4 xt720 loved most of the tested but CyanogenMod is my favorite
my last rom was Mioze7Aes cm6.3
so again thanks to all and back to the now
things i missed/bugs found:
still no crystalltalk
missing the standard gallery 4 hdmi /the realhdmi app i used on cm6 although not working
fixed in the builds i got from
https://github.com/peshovec/playground/downloads
when i push hardwaremenubutton/manage applications/running it shows me 0-15mb free ram most time i locked 0-5mb
when i look in other tools like android assistant it says 25-60
is it a bug or is it only cause i have no plan about the ram use
btw what about swap saw the qestion in orginal thread too can we do it the same way like on Mioze7Aes cm6.3
other people with same problems ? some are altough talked about in the orginal thread

hi jensblau...
i'm having the same difficulty with the 10 post issue.
i would also like to post to that forum topic
---------- Post added at 08:27 AM ---------- Previous post was at 08:06 AM ----------
i apologise for the short messages i may post but maybe we can get our 10 post minimum requirement on your thread. or possibly this thread will catch a developers eye and acknowledge our posts.
i have tried many versoins of the roms. however due to functionality and asthetics, i always find myself flashing back to dexters froyo.
i have not been a fan of AWD launcher as the primary launcher of any of the threads until i flashed this CM7 rom. the transitions are smooth and it looks great.
here is a list of things i have found on my side regarding the rom, i have only used the latest build [30.10.2011]:
Camera issues:
hd recording: initially when i went to recording, it partially worked but the screen looked like a tv with an interlacing issue. now the screen is just blank. i'm not stressing too uch about this as the hd recording was never really reliable on any rom, including the stock 2.1.
Widescreen photos: this one bugged me the most so far. there is no longer the option of taking photos in the native aspect ratio of the screen, which makes the phone seem less impressive in the gallery as pictures do not fill up the screen.
Applications:
i have not tested the GPS as extensively as you [30mins] but so far no issues. i cannot seem to successfully launch any gaming applications, whether graphics demanding or not. games just seem to hang on the loading screenshot and shortly after force close. i am not sure if the games cannot load due to an accelerometer issue?
is anyone else having gaming issues?
Memory::
RAM: seems inconsistent, whether 50mb+ is available, or 15mb, i cannot seem to run apps smoothly.
Links2SD: cannot link applications with links2sd, i have triedformatting the partition to all supported formats on the setup screen of the application but still no luck.
other than these issues thus far, i think this looks like a very promising rom
My problem is I can't charge when phone turned off, stuck at M logo @@
gps/navi
my navigation problem was the loadingcable from usbradio in the car it seems
without cable no reboot no force close dont know if the radio is the problem or the phone
@shalzn that was my hope to someone of the other thread recognizing this
@jjackichan works 4 me had that problem with an erlier build
update-cm-7.1.0-MilestoneXT720-beta-26102011-signed.zip was it i think are you running update-cm-7.1.0-MilestoneXT720-beta-30102011-signed.zip
bzw i reflashed 2.1 betwen what i didnt before since cm6.3
swap
this is the thread i found and used on cm6.3 4 swap maybe i ll give it a try at we
i used the file from post 5 i think
http://forum.xda-developers.com/showthread.php?t=1210343&highlight=swap
is there a way to switch ext betwen 2/3/4 without formating it
If you nandroid backup then restore sddata it will restore as ext2. In Mioze7Ae's recovery mod for the xt720 there is an option to convert ext2 to ext 3/4.

Converting along this path ext2 -> ext3 -> ext4 is pretty easy. Going backwards isn't very easy. If you just want to gitrdun, use ORXT720 to make and restore a nandroid of "SD Data". This will automatically backup, format your /sd-ext as ext2 and then restore it's contents. Then you can use "SD Card Utilities" to change it to ext3 or ext4 if you wish.
thx 4 the fast help
nice this tock not long time you found our nerdthread big THX 4 your help
maybe you can answer the qestion about swap too
is it possible like in your cm6.3 with fjfalcons CustomCore3.rar

I think it does. I just booted boot2.img from CustomCore3.rar and it came up with swap enabled. But, swap seems to make things lag quite a bit from what I can tell. It shows 60MB free after boot. I think we have too much memory pressure with our current minfree settings so too much stuff is being forced onto swap and we're thrashing. So, it will probably need tuning using something like AKMO or maybe my swap is just too big.
Caveat: I didn't use the other parts of CustomCore3.rar (because I'm on linux). Also, the build I'm running is very close to the one fjfalcon built and released, but it's not the exact same one (nothing about the swap support should be different, though).
You'll find that our forums are a bit more friendly than some of the others out there. Just keep posting until you reach the min to get into the dev thread and then you can ask directly.
AKMO-autokiller memory optimizer is going to be your friend for awhile until you get your personal memory issues worked out. It is free in market and set it to optimum setting to start out. Then once you get the hang of it, you can tweak at will.
thats the plan
love this forum it allways helped me with my problems
next qestion is how to use akmo strikt or optimum bzw one of the others
wich do you use
and what heapsize should i have tested 32 and 40 i think
but will edit this afternoon after checking this no time have to go to work now
edit:much better after installing akmo
Go with 32 heap size for now and use the optimum setting in AKMO for a bit to get the feel of it. Then we can work on tweaking that. When I was on Kahls V4 my heap was 48 and my custom AKMO were 16,16, 74, 82, 90, 98 and usually had high 50's to mid 70's free ram always with no swap boot. That was on that ROM, not CM7 though.
@ woodrube...
hi there, i am fairly novice compared the skills of the others. i think the reason though is that many of the bugs reported concerning baseband, market. disappearing messages have not happened to me.
in connection with your post above, could these settings be keeping me from running graphics intensive games? they all hang at the startup screen and force close. nfs shift ran superbly on my stock 2.1, and dexters froyo. but now it seems nothing will run unless i rsd my stock rom. i tried brian lee's 2.2 v1.7, which runs the smoothest out of the lot, but still no 3d games.
i would like to be able to run at least something decent to show off on CM7...
You just need a lot of free ram when you run those games. The AKMO tweaks will help with that. I suggest getting Titanium Backup Pro (root) version from market. It is well worth the money. Go into settings, apps, running services and you can see what is running and how much ram it is taking. You can use TB to freeze renegade system apps that eat ram. This will free up available ram to run heavy games. Another app is Chainfire3D with 3plugins. It is used for Tegra gaming and graphics. I can upload the plug ins later on this evening bc they are a pain to find on the net. These should help.
Edit: Chainfire3d app is in the market (root) but I uploaded plugins here http://forum.xda-developers.com/showthread.php?p=19090240#post19090240
@ woodrube
tried these apps. but no luck. as well as V6 supercharge, tried a few of the modes.
the titanium backup pro does not function as you described to view running apps, unless i'm missing something.
i have 61mb free an not able to run anything.
going to rsdlite back to 2.1 to test the games to see if its not something that changed entirely on the phone.
will give feedback and maybe you can assist from there. have you managed to run anything graphics intensive on your handset just?

NFS will not run on this 2.1, i dont recall if i have ever gamed on this sbf. do you think the problem could start with this rom being the start point of all flashing?

Titanium will not find the rogue running services, it can freeze them. Say you do not use Maps for example. Go into Settings>Applications>Running Services and see if it is running. If so, then you can go into TBPro, find the Maps app and "freeze" it, thus preventing that app from running and eating up valuable RAM in the background. FYI without running Swap boot, 61mb is reasonable. I do not run graphic intense games, so not sure if the problem is the 3D graphics, available RAM or something else.
Looks like the SBF that you are running is the Brightpoint one. Maybe try the Cincinnati Bell Wireless one. It is in the SBF thread and has proven to be one of the most stable SBF foundations. I would suggest you try the CBW SBF if you want to test on 2.1 or maybe try one of the other ROMs and test on them to see if it works on those. Don't forget that CM7 is still a work in progress. Build up your posts so you can post in that forum. Others in there might be having the same issue. There are a few gamers over there.

The differences between the brightpoint and cbw sbfs are inconsequential-- just things like default homepage in the browser and preloaded bookmarks.

He is just having 9 kinds of hell getting that game running. Bet Libertymonger could help him since he runs games like those. If he is having this much trouble getting the game running, I dare not say anything about running swap.
thanks for the help guys.
i'm beginning to think maybe there is a problem with my older apk's and data files.
all the games that used to run on my stock rom and dexters froyo are not running anymore on any roms.
however i have gotten NOVA, and Samurai II [tegra 2] to run smoothly and from the experience they seem to be more involved games. so in theory the phone and roms should not have any difficulty with the older ones. so i'm gonna give it up as installation issue. plus i dont really like nfs, it was more of a show piece in the losing battle against blackberry amongst friends...
i have tested the above mentioned on bravo 2.2 v1.7, and cm7. runs a bit smoother on the bravo for now. but it will keep me happy until the kinks are out of cm7.
would you recommend me running swap boot? will it increase performance? or should i not tamper too much now that its running?
BTW, free RAM has dropped like crazy. +-25mb. nothing major running. keyboard t9 mod : 8mb, google framework: 9mb, whatsapp: 10mb. the remainder add up to under 2mb
does this sound right with those figures?

Hi,
I do run swap boot on CM6.3 and have seen almost all games working better except a few (9mm which was quite laggy even after a swap). But I think problem with swap is that It freezes my XT720 once in a while.
BTW, I plan to switch to the Bravo V1.7 for the time being as I want to try HDMI out which I never used even in the stock due to its limitation of gallery view. Does the Bravo HDMI out work on any games?
Thanks to all the Devs for keeping my XT alive.
Cheers
Here's what this thread is about...the Sidekick 4G has a lack luster of performance in regards to speed...so I have a proposal.
Everyone shares tips to speed up the Sidekick 4G...after a brainstorm and some testing..I will compile the best tweaks together and put them into a thread and give credits to the appropriate people! Everyone feel free to join in, don't think any idea is a bad idea, just post it!
1. Tegrak Overclocking on Bali 2.2 at 1.3 GHZ (Generic Ginger 3.0)
2. Using Supercharger V6 Script
3. Use a good launcher (LauncherPro, Nemus) Customize all memory settings for the launcher in the launcher's settings.
4. Flash the Blaze 4G Modem
5. Uninstall the factory default Swype using Link2SD and install Swype Beta
6. Fix permissions on a daily/weekly basis depending on amount of usage
This is the basics of tweaking that I have applied to my Sidekick to get a boost out of performance. Share yours for everyone to use, and brainstorm.
Edit : This research is going to help me compile and cook a ROM. So helping out here, helps out everyone else in the long run.
I'm still on GOv2 now till I get my phone back, but at 1.2ghz along the tweaks I found in other forums this device is totally lag free for me just as long as I keep it optimized. My only issue is ram, I wish this device had more ram.. my low budget Androids actually BOTH have 512mb of ram, and after killing all running apps on those I usually end up with around over 300mb of ram, the Sidekick usually drops to below 100mb in no time and when freeing up ram I never seem to get at least near 200mb.
Anyways.. back on topic, I'll try to find the links to those tweaks so I can share them and give proper credit.

Unfortunately, everyone has mixed success with overclocking on Glorious Overdose V2. If I so much as touch 1.2 GHz, I'll freeze within minutes if not instantly.
Overclocking on GOv2 is hit and miss for me. Sometimes, it can go for about a week on 1.2, or like this morning, it'll crash and shut off. I almost did not wake up in time for work. lol.

Yeah. Which is why I'm trying to also dev like Adjust is, but I'm a beginner. I'm trying to find the Bali 2.2 Voodoo kernel right now so I can get started.
The Bali 2.2 Voodoo kernel is overclockable to 1.3 GHZ (stable) so if that's the case, just being at 1.3 is a huge speed increase, and then implementing the tweaks into the ROM.
it doesn't matter what the kernal allows for clock speed, every phone is different and some can't overclock at all without crashing

True. But at the very least we can try.
Try this and see if it does anything for your device. Just remove any prior init.d scripts you have on your device as these may actually conflict with each other.

cool deal. I was away from the SK for a long time, but isn't the Platypus_Egg kernel basically the Bali kernel adapted for the KJ2 ROM base?(correct me if I'm wrong about that) in which case, you can use the zImage from GOV or GG ROM. I guess it depends what you are gonna use as your base. for KG2 there was a flashable zip for the Bali kernel here and on Rootzwiki... but they might have been posted to Multiupload and not working anymore.
I am running the KJ2 stock ROM with Platypus kernel taken from GG, and it's running great. I also tried to build the kernel from the source we have, and it seemed to build with no errors, but I couldn't get it to boot on KJ2.

oh cool, I have a 2nd SK in my possession right now, so I could flash it and test it a little bit if you'd like. wouldn't be able to flash it until tonight tho.
Maybe by Friday I'll be able to get my hands on the Sidekick again.

Sounds great. I need all the feedback and help I can get.
1) Back up data (you will see why, below);
2) Make a list of all installed apps and their source (Google Play, Amazon, etc.) so they can be re-installed later (you will see why, below);
3) Perform a Factory Reset (this wipes all data and installed apps and brings phone to a "like-new" state --this is reason for steps 1 & 2)
4) Install a Task Killer. Easy Task Killer Advanced works well for this: https://play.google.com/store/apps/details?id=com.mobo.task.killer -- this not only kills background tasks, it also keeps a record of what is killed so you can easily keep a record of what apps keep re-loading into memory.
5) Root the Phone (help on this is here: http://forum.xda-developers.com/forumdisplay.php?f=1128); This allows access to the phone storage area where you can remove bloatware apps (like DriveSpace) that continually load in the background, eating up valuable resources.
6) start removing apps (again get help from the XDA forum for guidance) try MOVING an app (especially those from step 4) from phone storage to SD Card, then reboot the phone. if the phone starts working in a weird way, put the app back. Keep trying this with different apps until you are satisfied.
7) start re-installing apps --try only installing the apps you really need. move as many apps as possible to the SD Card. if a non-essential app forces install in Phone memory, uninstall it. only reason to keep an app in phone memory is to use its Widgets.
I have done all of the above on my own Sidekick 4G and the phone works much smoother.

For #6, do you have a list of apks you successfully removed. I removed a lot, including the logmein services and any apk with the word "test" in it. I have tried removing some others that I think I don't need, but many cause problems. I wish we had a list of all the removable junk (or that ROM cookers would just remove more apks from the system then they do)
For #7, I have to disagree. Apps load faster from phone memory for me, even with a Class 10 uSDcard. Phone boot up is faster (media scanner is much faster, you don't get ugly icons while waiting for them to be read off uSDcard, you can run your apps immediately after boot instead of getting "App Not Installed" until the are read off uSDcard). If your uSDcard dies on you (happened to me twice) your phone remains the same (I also like having the ability to swap uSDcards on-the-fly, like if I am on a trip and have multiple cards of movies).
We have plenty of space to hold ~80 apps and that space it just wasted if we don't use it. I have actually started doing the opposite... integrating more important apps in to system. That way there is even more space on data for other apps, and I can avoid having any apps on the SDcard at all (and still have plenty of free space in both system and data).
ok, heres what im going to do in the next week or so, im going to take time to figure out what apps we dont need through testing and remove as many as possible, then i will put it up for flash. we will see if i can get the zip down to 120-140 mb in size
Hello,
I installed (with pain) the official stock jelly bean on my GEDified Xoom. I thought "project butter" was a real big improvement, according to what I could read in many threads, I was then asking myself why, if it's such a big improvement, the release name didn't change to 5.0 instead of 4.1.1...
Now I have my answer !
Launcher :
I can say yes, there is a fluidity enhancements, but not as much as expected. I could not see much differences between ICS and JB regarding the fluidity, the stock launcher has only been improved a bit : if an icon page is full of icons, with 2 widgets on it, then there are a few lags ...
I use Nova launcher since ICS, and this one is really smooth as butter, much more than the stock JB launcher. You can put 3 or 4 widgets on a same icons page with absolutly no lag at all.
Web browser :
The same with the default JB web browser : I can feel improvements, but some web pages (with no Flash activated) are still laggy ... Compare it with Opera Mini and you will see what smooth as butter should mean ! Opera is just perfectly smooth, no lag at all on any web page.
Non-Google applications :
I couldn't find any fluidity enhancement when running non-google applications. The applications which where laggy with ICS are still laggy with JB, and unfortunatly, perfectly smooth Android applications are too rares ...
I can't even really use most of the new features of JB :
- I can't use the new icons auto-rearranging when moving a widget on a page as the stock launcher is not smooth enough for me, I use Nova Launcher which is perfectly fluid but does not have this feature.
- I can't ear the beautifull voice of Google Voice Search, as I'm french, and it only works for English language ... But I'm not even sure the problem is here, the main problem is that on the official stock JB release, there is no "download offline speach recognition" option in Google Now, so you just cannot activate it. But you can do it on a Team EOS ROM !!!!! This is a shame !!!
- I forgot this one ... I even lost an important feature ! My external SD Card could read or write with ICS, now it's READ ONLY !!!
As the fluidity is my main concern on my Xoom, I was disapointed, I was expecting too many improvements when I read threads of people testing Jelly Bean, so by making this thread I hope I will help people not yet running JB to not be disapointed as I am.
Now I hope the "project butter" is not closed at Google as there are still many improvements to do on this point, I can say that because some third party applications are perfectly smooth where the Google ones are not, so it is not an hardware problem, I am pretty sure that a dual core tablet should be enough to display 2D applications smoothly. But will our good old Xoom receive the future major Android release ? I don't think so as we are already lucky enough to receive JB after more than one year of existence for the Xoom ... But there are still a few bugs to remove in JB, I hope Google will update it (I never had a single crash when running ICS, on JB, I had one the first day I used it when I tried to change the background wall paper, my screen became black and the Xoom rebooted ...).
So now I am thinking of trying a JB custom ROM, but it was so painful to me to restore all my data and applications after the official OTA update (my bootloader was unlocked so the OTA didn't work, I had to put back my Xoom to a factory state with locked bootloader which let me loose all my data) that I'm now a bit lazy and not sure that the custom ROM will be smooter than the stock one.
I have HTC One X and if I get the same JB results on this phone I am definitely giving up on Android and testing Windows Phone. There was a Nokia promotion at my school a few months back and I tested one of their models with Windows. I was impressed by how fast and lag-free it is. I would definitely give it a go.
This phone that I am using has a quad core cpu, 1gb of RAM and what not and OS still lags!! I mean come on!!

Did you compare the EOS rom to the stock one ? In fact I would be glad to see a video of the Team EOS release running on a Xoom ...
One of my friends tried windows phone and said it was like running a Beta. Came back to Android.
Major benefits were integration with Xbox.
Windows tablet may fair slightly better but the ARM not being able to run current apps seems a bit like cutting of their arms
I don't think there is cause to assume we will not get KLP (Android 4.2 or 5.0) yet, its a year old. Google seem to want to support devices for 18 months as per last IO...?

It's time to be honest- there's only going to be so much ANY software can do on our Xooms, as it turns out that part of the issue is a hardware problem- but not where you'd expect. One of the things folks don't realize about Android is that the performance can be heavily dependent on the type, kind and size of the Flash disk storage a device contains. Flash storage, especially the what's-now-older kind that's on our Xooms, just doesn't perform very well if there's a lot of small, random writes to it, and there's a lot of these in a typical running Android system.
What ends up happening during these small writes is the system can end up waiting a relative eternity on any other disk-based I/O once the Flash controller chip (the one built into the Flash device, not the controller on the CPU) determines it's time to reorganize itself- and what that means is that during that time, the system can (and often does) appear unresponsive, or "stutter". I've worked on several Android handsets and tablets over the last few years, and this problem is beginning to be well-known.
A good example of this is to try listening to music, then browsing a complex webpage- as the browser writes its cache and various database files, many times the music will pause, stutter or click.
I've been doing what I can in EOS kernels to improve the random-small-write performance of the Flash disk- changing when and where writes happen, changing the geometry of where they occur, and I'm now actually testing a series of changes that are based on an academic Whitepaper that look quite promising (but it'll require an entire "Factory Reset" type wipe to make it work).
BTW, if you want to see something eye-opening, run PassMark (or some other disk-I/O benchmark that compares against other devices) and see how badly we do against more-modern devices.
(TL;DR: newer handsets and tablets will likely perform better on JB, mostly 'cause our Flash devices could perform better in many often-used scenarios.)
Thanks a lot for this answer, I understand what you mean about flash memory.
But there are some ways, with the current Xoom hardware, to make things very smooth as some third party softwares do it :
- Nova Launcher -> Perfectly smooth, no lags whatever the number of Widgets are displayed. JB Launcher is much more laggy ...
- Opera Mini -> Perfectly smooth, and very responsive.
So I really cannot understand why Google cannot make things smoother if other companies do !
Plus some apps have perfectly fluid menus (I mean when you just scroll a menu, it's perfectly fluid) and some other apps have their menu so laggy ...
So I really feel like it's not a hardware question but more the way the apps have been developped.
and what about the Linaro code ? Wouldn't it make JB smoother ?
Opera Mini isn't really a fair comparison. How does it compare to Opera Mobile or Firefox or Dolphin or whatever? Opera Mini was intended for small memory devices and doesn't even render the pages locally. The are rendered on Opera's servers and then the result is compressed and sent to the device to be displayed.
I'd say your comparison regarding the launcher though is valid. I haven't personally experienced much lag but I don't have many Widgets.

Go EOS you will not be disappointed!! I was very disappointed when ICS came out for my stingray Xoom i didn't even stay on it for more than a couple hours after getting it OTA before i went and flashed the EOS ICS ROM.
As for browsers i love Dolphin HD.
I have stock JB on my Xoom and other than minor launcher lag with multiple widgets, I find this to be really smooth and 100% stable. I see very noticeable improvements over ICS, especially with graphics and overall the smoothness. Overall I am very content.
I will also say, the battery life has surely improved over ICS! For 3D gaming, I lose about 7.5% - 10% in 45 minutes, which projects to about 7.5 hours of gaming with a possible max of 10 hours!!
Sounds like project rusty beans on your Xoom then.

I was wondering if many of the Project Butter enhancements were launcher related. I've always used Nova Launcher as well, and I have seen lag in the past on ICS. Especially since my desktop consists mostly of widgets. PB Launcher is definitely a little better than Nova when loaded with widgets, in my experience. But the ability to customize rows/columns and get rid of icon labels is compelling enough to use Nova. Nevermind the ability to utilize most of the screen without a 1" border on each side, as is the cast with the stock launcher.
One huge difference is with the Netflix app. I remember them talking about Project Butter enhancements to the Framework during the I/O keynote speech, and I suspect the changes helped almost completely eliminate the AWFUL lag I'd experienced in the Netflix app in ICS. Once a show got going, the streaming was fine. It was when navigating through the app that it was horrendous. In JB, it is great!
Fix External Card Write problems
Dizzy,
I had the same exact issue when trying to write to my SD Card - it was write protected and only allowed read permissions. I had problems restoring backups with Titanium Backup and creating new ones - as my backups were on my External card.
I found the solution which seemed to cure-all. I found it with this post: http://forum.xda-developers.com/showpost.php?p=20869996&postcount=7
Basically, assuming you are rooted, in /system/etc/permissions/ mount this folder using ES File Explorer or Root Explorer as R/W, then open platform.xml in text editor and find WRITE_EXTERNAL_STORAGE permission. Add an additional group definition for this permission...<group gid="media_rw" />. Save changes or exit and save changes and then reboot tablet.

Thanks a lot for these informations, unfortunatly my Xoom is not rooted (I had so many problems to update to JB when my Xoom had the bootloader unlocked that I had to re-lock it...).
So I cannot use this solution, and I don't understand why Google put the SD card Readonly where it was read/write in ICS ...
This is really a big disapointment for me from Jelly Bean. I hope Google will change that in the next JB update.
I have tried Jelly Bean as well and noticed that while it is a little smoother than ICS, it isn't "buttery" smooth. That said I don't believe it's so much the software as it is the hardware. Tegra 2's GPU is quite lacking in general and was a huge letdown for many people. If for example you check out JB on an Asus Transformer Prime/Infinity or a Nexus 7, you'll notice it is MUCH smoother overall. Finally, a lot of older apps haven't been updated yet to use GPU acceleration but there is a setting in the developer options to force gpu acceleration which should make those apps perform better.
My Droid Bionic running an ICS leak is smoother than my Xoom on JB simply because it has a faster gpu. The only thing I really noticed that helped with my Xoom's performance was running it at 1.5Ghz OC on the Team EOS rom. There are still websites that lag and have issues, but in general it does run much better than stock.
As for WP7 it is a smooth OS yes but VERY incomplete....WP8 looks to address many of the issues with WP7 but it will also break a lot of compatibility yet again and will basically alienate the current entire WP7 userbase...(if you didnt know WP8 will run most WP7 apps, but WP7 can't run any of the WP8 apps).
Is it just me, or does the Xoom seem to get faster over time with Jelly Bean? I was part of the soak test, so may have had it a few days loner than most, and I have done a couple of resets early on, but over the last couple of days, it definitely seems snappier

I've got a mz601 and i have to say that JB is totally lag-free on my XOOM. I've never used stock firmware (EOS only) and after updating from ICS (that was laggy as hell) i havn't seen any lag whatsoever. But when i updated to JB i did a complete factory reset (formatted system, user data, cache, internal sdcard and external sdcard) and it was as if i had bought a new tablet.
Stock JB launcher has no lag, system ui has no lag, browser has a little lag when opening complex websites, music and videos have no lag. Also Flash works much better (even if it's not officially supported).
Some apps still lag like they did on ICS but i guess that is an app developement problem since most apps also work lag-free...
GO... GO.... GOOGLE... Android just keeps getting better and better...
PS! I also have the original iPad and that lags alot with ios 5. I also have a powerful desktop-PC (i7 with 8gb ram) with windows 7 and I have to say that the XOOM opens websites faster and scrolls much smoother (even with a bluetooth mouse).
PS2! I'm not an android fan. I like all gadgets but android seems to be moving in the right direction.

I have been very critical of JB since getting it last Friday but I have to say that today the whole experience seems to be coming together and some of the early faults I was experiencing have pretty much gone all of a sudden.
It seems quicker now though only marginally but thats still a step up from how it was at the beginning. And since switching to chrome instead of ICS browser it seems to be giving a better browsing experience; which was definitely not the case with chrome on ICS for me.
Bit confusing here, as I understand that ROMs and kernels for the Optimus V (VM670) are incompatible with the P500. I don't see much for the VM670 in the Android Development section.
I recently flashed BobzHome. The camera apps occasionally freeze, which I blame on the camera drivers in the kernel, and when overclocking the only governor that doesn't freeze the phone is Performance - again, points towards the kernel.
ICS for the VM670 seems to be a downgrade from Gingerbread because there is no HW acceleration. "Inferior Human Organs" is not a comforting name for a ROM.
Is there a list of ROMs and kernels for the VM670?
There's tons of roms out there. I can't post links, because I'm new to xda, but you should be able to google these and figure out where the ov roms are.
I love theKraven's cold as ice (cai) ics rom. It's build for the S, but works great on the V with the virgin patch. Basically everything works except native tethering. It's as fast and smooth as I've ever seen my phone.
BobZhome's jb and ics are both good, but Bob hasn't had a lot of time to fix bugs, but it looks like he may be getting back into it.
Tdm's Quatrimus ics is also good, but same as BobZ, hasn't been updated in a while.
Thatguylurkin ported icysnap using cai as a base that is cool, but could use an update. I'm hopeful about that.
Then there's the gb roms, For the most part they are solid. Most overclock well and are fully functional. This list is not comlpete, but these are ones I've tried and like (in no particular order):
Mrg666's mirage build
Leslie Ann's harmonia build
Earthnfire78's om-mandylion
Tgl's gingersnap port
Sellers86's cyanmobile experience port
Beyond that, a few good ports from clodfelterac and ilikechicken, and there's tons of other quality froyo and gb roms. Sorry if i missed anyone, those are just the ones that come to mind.
Recoveries:
cwm is the gold standard, imho. There's a few options, BobZhome, green, Earthnfire78's zen garden
New Cot 2.1 is great.
Twrp from theKraven is fun and cool.
People like Xionia, but i never found the right .img.

Thanks. But none of the JB or ICS ROMs support hardware acceleration, right?
And from my own research, not all of the VM670 ROMs that you say are solid, are solid.
And which of those ROMs support overclocking?

for ics omx libaries has been released
so their should be hw accelaration in ics
roms
I guess solid is a relative term. I would call most of those solid in that all of the key functions work, and they don't tend to crash. Hardware acceleration is still an issue, and idk if it will ever be fully addressed on the ov, but at least Kraven has fixed hq video/youtube in cai. That was one of the main issues that people said would never be fixed without hardware acceleration.
There is an egl patch to force gpu rendering, but idk if it really makes a noticeable difference.
As far as oveclocking, in my experience, none of the ics/jb roms run well over 600. They also can't handle underclocking well, so you need to raise your min clock speed to 480
In general the gb roms overclock well into the 700-800 range, but it depends on the specific rom and your specific phone.
So if I want to overclock, I'm going with a gingerbread ROM.
BobZHome is crashing on me, especially when I try to use the camera, so I blame the kernel because camera drivers are in the kernel.
Can you recommend a good kernel that overclocks well?
If that doesn't work, can you recommend a STABLE GB ROM that overclocks well?

Mirage was used as the base for a lot of the ports, and has a good reputation for overclocking. Harmonia 2 is also well developed.
In general, I don't think there is much of a speed difference between the overclocked gb roms and the non-overclocked cai.
I would start by trying cai and mirage, and move on from there. I think those two will definitely suit your needs, and you'll have to decide which you like better.
ps. I just realized we are conversing on two threads. Sorry, sometimes I don't look at whom I'm talking to.
You know, I just realized we are conversing on two threads, too!
Let's keep it on this thread? The title is more appropriate.
I'm going to stick with GB.
Does USB mass storage work for Mirage?
It does.
WOW! Installed Mirage and boy am I happy! Runs like a champ, overclocked up to 787MHz and so far no problems!
One issue, instead of a Google account, Add Account asks "Add an Exchange account." How do I add my Google account?
Also seems that LGCamera doesn't like the VM670.

When I go to Settings > accounts and sync, when I add an account it only asks for an Exchange account.
I had installed Mirage over my existing install, so I kept all my apps. I'll reinstall gapps and see what happens.
@upconvert, with Mirage can you tell me what are your CPU settings for Min/Max & governor?
What rom were you coming from? I'm pretty sure that there's a "first time setup" included in the gapps that will tak care of that. I think it also includes the google sync that will let you add it from that menu.

I was using BobzHome. But that's not my problem. This phone keeps crashing on me!
What are the recommended settings for Performance? Maybe I'm running out of memory?
The first thing I would recommend is a full wipe before flashing. You can back up your apps with tibu or mybackup root first. I know it's a pain, but it's hard to figure out what's causing crashes when you're working off a dirty flash.
As far as performance settings I would say to start your min clock speed at 480, and then experiment with the max clock speed. Start high and take it down a notch every time it crashes until it stops crashing, then go one notch lower to be safe. Once you have your max setting, then you can do the opposite with the min speed. Start it low and click it up after any crashes.
I also like 16 bit transparency, allow ksm and purging, and disable dithering.
Well, I did what you said and did a full wipe. From the recovery menu I wiped cache and data, cleared and formatted Davlik, formatted all the partitions.
Installed Mirage and everything ran fine! I installed gapps and that fixed the Google login. Installed DroidWall, then AntTek App Manager, everything O.K. Installed Titanium Backup, ES File Explorer, inSSider, MX Player, QuickPic, TuneIn Radio.
Played with all these for awhile and everything seems O.K. then installed Radar Now to really start pushing the limits. Everything O.K.
I then installed Google Maps and that's when it hit the fan. Crashed @600MHz while running Maps. Crashed on next boot and every boot after that. Crashed within about a minute of each boot. It then became a race to boot the phone and get to AntTak App Manager fast enough to freeze Maps. After a frustrating 20 minutes I finally got there fast enough and froze Maps. My OV froze in one last protest, I pulled the battery and started it up and everything's fine now.
Maps likes to run in the background so I guess it's doing something nasty. I'm CPU max at 729MHz and it's flawless. Gotta find a good offline GPS map program.
