I've been having this phone for a year, and I've finally had the guts to go ahead and root the phone. I now have super user application. I have also installed Link2sd and linked all the big apps to a separate ext2 partition in my SD.
My question is , now since I've rooted this, what all options are there for me to explore and try out, in making this phone better. I've seen about various Cyanogen Mods, CM 7, CM9, CM10. But they all seem to have some issues. But sometimes even simple issues may be blown out of proportion. I just need some feed back on how bad the issues are, or how good the mods are actually. Basically I want to know if the impact of these certain issues will hinder me in enjoying my android experience. And i couldn't think of a better place to put these questions to.
Summary:
1) What options are present to make my device better, now since I've rooted it?
2) What kind of serious issues are there with the CM versions, and whether i can enjoy the phone despite these.
PS: One more thing. in Link2SD , despite linking those Apps to the ext partition, the internal memory only has 75 MB left, and some portion of it is reduced everytime I install a new app. is it a bug, or I've done something wrong?
I was afraid of rooting first too, but now that I rooted it, it totally worth it. First, I installed hexgore's stock plus rom with some modifications and used it for almost a year, then I decided to try out cm9. It was a lot better, and had almost zero problems (everything was working except the front-facing camera). Yesterday I installed cm10, and it is even better than cm9 I recommend you to install cm 10.
For making your phone better, you can install One Power Guard, Total Commander (give it root permissions instead of java), Cache Cleaner and Super Backup. These are the rooted apps I use/have used in the past.
Your "problem" with link2SD is not a bug, it is how it is supposed to work. It links the apk, the dalvik-cache and the cache, but it does NOT link the app's private data, which then is stored on your phone's internal storage. And that is taking up space.
Have fun with your rooted chacha!
Thanks
Thanks for your suggestion, I have decided to give CM10 a shot. Now, can u please send some link of a guide to follow, in order to flash CM10 in my HTC ChaCha. Also, a guide to revert back to the current ROM in case I fall into some issue with CM10.
Also, I wanted to know, is there any improvement in the battery? Mine is a year old and lasts for about 11 hours max. Anything that can improve this would be of great help.
I had earlier gone through a post on modifying a system file with a # sign in front of a line which makes the battery better, but I was unable to figure out how to edit a system file(I've located it using Astro file manager).
And I cant post there, since the forum rules say that the user must be at least 10 posts old to post in the dev section.
Any help is deeply appreciated.
Thanks in advance

Heyy!
I took ur advice and installed it, and there is almost no problem for me, I never use much of the front camera anyway. The thing is, the Keyboard backlight doesnt work when the brightness is on automatic. is there a work around?
Also, the prediction, as I mentioned in another thread, does not work good. there is no prediction as a matter of fact, no options come out for me to select.
One more thing is that I am unable to see a list of users to select from that and send messages to. I have to type in the name of each user and add it manually. Any work around or apps available to solve it?

Hi all!
I've been regularly testing new ROM releases by the gurus here at XDA on my AT&T Tilt. Each install has been everything from a "close to the brick" experience, to extreme jubilation with new found speed and features. But, one issue keeps re-occuring and I'd like to ask what the best practice is for loading a new ROM image?
I ask this because it seems that each load brings new oddities and new problems that seem to occur due to past ROM images being on the device. Like right now I'm playing with a clean AT&T based ROM. Strangely though the HTC home screen is not included with this ROM, yet after the first load, whamo! the HTC home screen showed up. It was not in the installed programs list, so I couldn't easily remove it. And installs (to create an image that could be removed) failed a number of times before it worked enough to change the installation.
That's just one scenario. And I've had a lot more in very interesting ways. Like for instance, Battery Status 1.04 Ext has a seriously stong liking to my phone. That program I'd like to keep, but it's odd that it is always there, no matter what I do. And usually in some odd state that makes it hard to use until I pound it hard enough.
Also, the time seems to odd too. Every other ROM install, I'm forced to reset the time on the device at initial startup. Otherwise the time is just fine on the even number of installs.
So, what's the best routine of tasks to complete to ensure that a ROM installs as cleanly and problem free as possible. Is there a way to "clear" memory properly so nothing is left over? Dutty once helped out by suggesting that I install the OEM shipping ROM first before anything new. But that even doesn't work 100% of the time. Any suggestions are very helpful.
Thanks all for the Great ROMs. I'm having a great time playing with all the new features and abilities you guys give these awesome little machines.
Scott
weird...
The only things I can think of are obvious, but here it goes. Have you tried hard resetting / clear storage before you flash a new ROM? Are these programs being installed from your computer activesync or something? Have you tried removing your memory card?
Good Luck
When I first got my G-tab I was baffled by all the instructions and the literally thousands of posts in the forum. Even now, I haven't been able to find exactly how (or why) I should update my kernel. That said, I have TNT Lite running and I love my g-tab. Exploring the possible uses and utilities on it provides hours of fun. Now - here is my question. I stumbled on some instructions for installing the ROM and I have used those same instructions to install several patches to the Rom. I see all this commentary on Clockwork, side loading, etc. and I wonder if I am missing something. Today I just installed the .25 patch for TNT-Lite. I downloaded the rar file, unzipped it on my PC to get the Recovery folder and the update.zip file. I plugged the g-tab into the pc and switched it to usb mode. Then I moved the old recover folder and update.zip to a folder (cautious me) and put the new ones in the root. I disconnected the usb and started the g-tab in recovery mode (holding the power and volume+ key. It rebooted, applied the patch and I was done. That seems simple enough. It would seem that this would work for switching roms, applying patches and probably even upgrading the kernel (If I knew where it was and why I should do it). Am I missing something? Everything seems to work.
Sounds like you got the basics ok.
The real main reason to update the kernal as i see it is to add things like driver support for devices like gps and g3, so on, also minor fixs. If your not using your gtab for anything like this you maybe happy to stay stock. But if you like myself like to use your gtab to surf with g3 or as a sweet gps, then thats what the kernal updates allow. Im sure others can correct me if ive got anything wrong or add to what ive said.
You got the basic steps right, but installing ClockWorkMod Recovery has a lot of benefits.
First, built in backup and recovery will save your skin if the gTab get "cranky".
Second, installing ROMs and/or updates saves you a few steps. From "tar" files (TnT-lite), extract the update.zip file to a folder (I created a folder named "xda", just an example) and name it after the version of ROM/update.
CWM will flash "*.zip" file. This way you can keep multiple ROMs/updates on the card and switch between them.
CWM lets you clear cache, wipe Data partition, clear Dalvik-cache (use caution there), fix permissions and so much more! It is a great tool.

So now we peel back another layer
OK so now the question of multiple roms comes up. I am not clear about the role of the rom - can I switch roms and keep all of my apps and data intact? I'm thinking like changing style sheets on a web page - presentation is different but the underlying data is still the same? Is it that easy?
And... if I am doing that perhaps I need to "clear cache" or "wipe data partition" but although I like to investigate new things I'm not willing to just walk up and push the big red button without knowing what it is for. So why would I "clear" or "wipe" things?
I get the impression that I could switch between ROMs just like switching between browsers on a pc - today Chrome, tomorrow, Firefox and never Internet Exploder... Is that correct? It took me quite a while to get the market working and it still doesn't work optimally but I'd hate to undo all the work I've done getting the g-tab humming along by switching roms. Can I?
So - anyone care to expound on the structure and how it all hooks together? What parts can be swapped out and what parts form the foundation? I'd hate to brick the little guy in my ignorance.
One final note if you know and you answer - where did YOU learn about this. Is there a book somewhere to read?
Thanks again for sharing your knowledge.
The Need for A Wiki
I'm in the same boat as enigma. I'm not even sure what ROM is an acronym for, though I think it means operating system. A wiki would be a big help for many people. I bet people would be glad to contribute.
Well, I don't know about Android book, especially about "hacking android book" , but this (and others) forum has plenty of reading material and guides. Not to mention people (a lot more knowledgeable and experienced than me) who will offer advice and lend a hand. And Google search comes in handy too.
Switching ROMs is almost like switching the OS, or a flavor of. Very much like switching between Linux distributions; the base OS is the same, but the overlay changes the user experience. Some things do change deep down inside, that's why is advisable to clear data.
Android, like Linux which it is based on, uses separate partitions for different parts of the OS, like boot, recovery, data, cache and user data. Plenty of write ups and discussions on the web on that.
So when flashing a ROM, you'll rewrite boot and system. Your user apps and data/preferences pertaining to those apps are stored in data partition, and since you are changing the 'OS', the apps need to be recompiled for it. Backup apps, like Titanium Backup, come extremely handy here: backup and restore apps AND appdata with a few clicks.
Backups are stored on sdcard, which is a lot like Linux /home directory, and do not get wiped during flash. Also the CWM (sometimes called Nandroid) backups are also stored there. A backup-of-the-backup is always a good habit (copy of /sdcard to your PC for safekeep).
This is just a quick rundown, hopefully that answered some of the questions.
There is a world of information available out there in "ether-world", Google is your friend.

I just installed Thumb Keyboard on my gTab last night and I guess I got carried away getting used to it!
Yes, I have found some very good step by steps (reflashed to vegan after reading that one). Step by steps are great but I 'd like to understand why I'm doing it.

The explanation that did surface in this thread was great though. Thanks. I'll keep asking questions. There are a lot of smart people out there!
Hi everyone
I am in need of urgent Help
I upgraded my Motorola Milestone XT720 from 2.1 to 2.2 using Cincinatti Bell Manual.
I referred this
http://www.cincinnatibell.com/milestoneupgrade/#howtoupgrade
Now, After successful upgrade, I have some serious issues
1) My Camera's Flash isnt working. I cant enable it.
2) Performance is low
3) Lost MotoNav. How can I get it back?
4) Even if I keep Pattern lock, the slide lock do appears
5) Also, How I can merge duplicate contacts? like one contact has 3 numbers saved that are same..
Thankyou
1. im not sure. should work.
2. performance is low. you can overclock using milestone overclock if you are still rooted. however, if you are not the kind who maintains you phone everyday, i suggest you go back to 2.1 as its the most stable.
3. just google motonav apk
4. thats a flaw in the rom, cant be fixed. if you'd like to try out custom roms and maintain you phone like most of us do here, then go ahead. its very exciting lol
5. you can merge duplicate contacts by signing in to gmail on a computer, click contacts and just look around the buttons. its called "find and merge duplicate contacts" if im not wrong.
hope this helped
1) Tried all level best best to start flash... It didnt. Installed Sleekcamera apk.
2) Google find and merge always crashes and unable to do the action
3) Whats overclocking? Is it a self explanatory software??
4) Dont feel like going back to 2.1...Love App2SD
5) I also have some issues - cant play HD video and my internal video player isnt working to its full potential as I am unable o avi file. I feel, that there is codec problem, as Ringdriod isnt working too...

if you like to have apps on your sd, there's a more advanced way to have it. i think its better than android's own move apps to sd. many roms we have around here have app2ext automatically set if they detect any ext partitions on your sd card. it moves all user apps onto an ext partition on your sd card (you have to use a partition tool to make this ext partition).
overclocking is actually just controlling your cpu clock speeds. most of us overclock our phone because it sometimes get laggy if we use the stock speeds. theres an app that helps us overclock on the market called milestone overclock. please remember that you need to be rooted do these stuff.
for the camera, you might have hardware problems. i dont know. contacts you should try doing the find and merge duplicates again. i'll upload a pic to show you what it looks like.
i recommend mioze's cm6 rom if you ever want to play around with flashing stuff. the stablest i've tried so far. Cyanogenmod is very versatile lol. there are a lot of themes for this rom too, made by Sileshn our master themer. for the videos i dont think i can help. you could try mobo player from the market (i think?)

This is baffling for me. I feel like M not too smart for smartphone
for the videos i dont think i can help. you could try mobo player from the market (i think?)
Yup, I have that. Unable to to pay HD vid. It shows a lag of sound and vid. Tried soft decoding. Didnt work.
Couple of things about this. Are you still Rooted? CBW gave root permissions and then I think later in the tutorial they tell you how to give it back. Don't give it back. For what you want to do, you need to keep Root permission of your device.
Next are you comfortable with flashing custom ROMs and doing realtive non-beginner stuff on your phone. We can help you and walk you through stuff but unfortunately, there isn't an "app for that". If so, then here we go.
If you successfully were able to upgrade your phone, then you can do this. There are many custom ROMS in our forums that you can use. CM6, Hellmonger's, Kahl's V4, Bravo (wip) and CM7 (wip). I suggest CM6 or Kahl's V4 as they are stable enough for beginners to learn on. The have 99% working everything and what doesn't work, is either being fixed or there are already work-arounds. (search the development forums for these)
CBW's ROM doesn't have app2ext. It only has the native Froyo app2sd where you can go to settings>apps>pick your app>move to sd. This is not the same as App2ext or Link2sd. In these you have to partition your SDcard with an ext partition. Do you know how to partition your SD card? All the above ROMs do have the native Froyo app2sd, so if you don't know how to partition your SD card, that is fine too.
Answer those and then you can decide to move forward or not. It isn't hard and you don't have to be super smart to do it, although the more you read around, there are some seriously intelligent people in here. It is just from reading your posts above, how comfortable are you? You will not brick your phone and make it a paperweight, we can bring it back from the brink, if need be. We've done it before.
**Milestone Overclock is an app in the market (requires Root) that is free to download. Just download it and set it at preset 1000/66 and you'll definately seem a boost in performance.
**Google contacts. If merge doesn't work for you, go into google on PC and look at your contact and you may have some duplicates in there. When i first got it, i had 3 of everyone too. Also, go into your phone and go to settings>account/sync and see what is sycnhing. Side note: if you have a Google+ account, unsych that as everyone in your circles will be put on your phone and vice-versa.
**Moboplayer. I use this all the time and have no problem seeing HD vids. Might want to take another look at the preferences. It even says it on the thunmbnails that it is HD.
**Camera. If you don't like the the camera function, there are a few on the market (mostly paid though) that work well. I use Vignette, but there is Camera360 and I think one for LG too. If your flash isn't working though, that might be a hardware issue.
Figure out what you want to do with your phone (flash custom ROM or not) and we can help. If you already flashed the CBW upgrade, then you are really half-way there.
Also sorry for the manifesto sized response.
Hi
Actually thankyou for detailed resonse. I find it very helpful. But, M disappointed to tell, that in afternoon,I installed Moto-optimizer after I couldnt work on Motorola Overclock and Started the process at 800...and then, its only M logo which is showing up.
Will give it to service centre tomorrow and get back to 2.1. I hope, they are not ale to detect this s/w fault..
Will love to learn our SD card partition,

Here are the directions http://forum.xda-developers.com/showthread.php?t=753170 See first post. It's easy to do.
Hi, I've installed several CM: from 7 to 10.1, lately many 10.1 nightlies and I've been using the Nexus S for years.
Right now I've installed SlimBean, build 6, thinking that my phone needed a clean up and a better ROM.
The problem is: the phone is normal after a reboot but after 3 days of being used without reboot it becomes unresponsive, laggish and the free RAM is always on 22 MB with plenty of services that keeps restarting.
By unresponsive and laggish means that sometimes I browse internet (under Wi-Fi or 3G, no difference) and even with the standard browser everything freezes up. Sometimes takes me 10 minutes to get the page and be able to quit the browser, sometimes screen goes of, BLD stays on if I push the power button but nothing appears for minutes and then it probably reboots.
Now on Slim Bean it seems a little better but the performance degradation are very similar.
Since other guys are installing CM 10.1 nightlies etc and are not experiencing my problems I thought it was a problem on my apps. I use:
Faceboook
WhatsApp
Skype only when I have to call, it's NEVER always on
All Google Apps
Cyandelta for getting the latest nightly
Titanium Backup
ROM Manager
Rarely: Chrome/Firefox/Dolphin (since browsing destroys perfomances permanently after browsing. Chrome is particularly slow)
When I told, in the other forum, what I use some guys said that they use way more stuff and they are not experiencing problems.
Please note: I've managed to reinstall CM 10.1 with a full wipe (data-factory, cache, format /system, dalvik from the recovery) and I did the same to try SlimBean following step by step instructions.
Now: I think that maybe there's a problem with some junk in my phone. I've of course run an Antivirus (AVAST) several times in order to exclude some malware and I've found nothing.
By browsing root, folder /, I've found:
/proc - 179 elements
/proc/irq: 159 elements old, some new (updated in these days) but all similar with empty files
The name of the folders is like: /proc/irc/11 to /proc/irc/164
Opening those files doesn't give me much information. Note I'm graduated in engeneering but I'm not pro android developer nor I do the developer for work, even tough I can understand part of this stuff
Also in proc there are other elements with empy files:
/proc/1
/proc/2
...
/proc/15289
Here's my question: since the full wipe raccomended in the ROM update/fresh install procedure has been done step by step, several times, and the phone is still experiencing the same problems (different ROM with different Kernels also), is it possibe that I've installed something that needs to be deleted in order to get the phone less laggish/unusable?
I see that if I access the recovery I can format the following folders:
/data
/system
/cache
/boot
Is there something else that I can do about other folders like, for example, act on cleaning/formatting the /proc folder or something?
What's safe to do? Is there any tool that I can use or a procedure to get the phone fully clean up and then reinstall a fresh ROM?
Thanks in advance for your time
you can't wipe it any better. if you delete some folders you can actually brick your phone. before flashing format /system /data and /cache, that's all you can do. the slow downs are probably caused by a lack of RAM, 4.2 is hungry for RAM and our phone has only 512MB. I tried a lot of 4.2 roms and all of them slow down and stutter after a few days of usage. 4.1 uses ram more efficiently and therefore is faster when you multitask. I use cm10 latest nightly and there are almost no slowdowns, i had my phone running for a month without a reboot. 4.1 is best suited for our phone, no wonder google refused to officialy update it to 4.2, the hardware is just too old.

Everyone is forcing it just because it's the latest version. The same will be when 4.3 gets out, people will install it just to have it, even if it's not stable. Most of the people notice the problem but ignore it just for the goodies that 4.2 provides. Some ignore it so they can tell their friends that they have the latest android. Some don't use many apps so the problem is not noticable.

Honestly the most strange thing is that there's a CyanogenMOD for this...
I don't think they would push it if it doesn't work properly... or am I wrong?
After I do a fresh install of cromi on my tablet, it's just excellent, fluid and smooth. After a while, the performance seems to detoriate. It has done so for about every version I tried and the same goes for my phone (An i9300 running slimkat). So my question is this: What makes an android device inherently slower? Is there a way to see what apps may slow down the performance?

That is a very good question...:good: I have the same question but I can not find a solid answer for it. I hope that some developers or experts can give us a good definition of it...
This is what I know but I may be totally off and wrong, haha..
When you first install the new ROM, all your partitions are new and clean. When you write something to your data partition, it is most of the case, it just writes data to a clean blocks without erasing the blocks. After a while, most of your blocks are dirty even though they are unused or available for writing. This is the part that users see the degradation. When a new data is writing to the available and dirty blocks, first the kernel has to erase the block before writing to it. The erase process takes a lot longer than the write process according to my research...:crying: On our tf700, writing to the internal sd or mmc is very slow already. On top of that, the erasing process has to be done before writing the new data to your internal sd. If you do the math, the performance of the writing will degrade more than twice comparing the new installation..:crying: I believe that google noticed this issue so they implemented the fsTRIM on the newer kernel source to tackle this problem..:good:
However, when you are using the fsTRIM, you have to sacrifice some slightly performance loss and you don't notice performance degradation over time.. During the normal usage, I can not tell the differences if the fsTRIM is on or off but I did see the small performance loss with a bench test.. In short, I know both _that and hund's kernel support the fsTRIM but it is disable as a default. You can try to enable it to see if it is solving your degraded problem....Good luck...:fingers-crossed:
Another method is to use the lagfix manually once a week or more frequently...
Usually I reboot to recovery, wipe cache (don't need to do dalvik), reboot back to ROM and everything is quick again.
I don't know why this works though.

I don't know why this works though.

Mostly correct.

When a new data is writing to the available and dirty blocks, first the kernel has to erase the block before writing to it.

It's the controller in the eMMC that does that. The peculiarities of flash memory - no way to directly overwrite data, need to erase in large blocks before writing, can't write to the same location too often or it wears out - are all hidden by a small (and not very smart, in our case) controller. The kernel sees a block device that it can use like a mechanical hard drive.

Another method is to use the lagfix manually once a week or more frequently...

This depends how much data is written and how much space is free. If you have 10 GB free and you run lagfix once, you won't benefit from running it again until after 10 GB have been written to flash. Random writes cost more than their real size (see above, overwrites must be simulated by rewriting larger blocks), sequential writes translate to about their actual size written to flash.

Thanks _that for sharing the information and time...:good:
I take the mostly correct and hate the least incorrect....:crying: Every time I talk to you. It seems like there is a language barrier. Oh yeah, it is called an Android language, hehe... I will loose a few days researching and trying to understand what you are saying...:silly: However, I feel like that I understand android a bit more in the end and thanks for that....
Now it is time for me to bang my head on the keyboard for the next few days...:crying:
Thanks for the insightful information guys, you are frickin awesome! . I thought the lagfix app was removed from CROMI, since the trim function was no longer needed after 4.2. I might be wrong about this, but in any case I have LagFix premium which can trim partitions on a schedule, and I take it that it doesn't do any harm at least?

I personally like the "discard" mounting option on Cromi x.. It is just my personal preference...:laugh: I don't recall that the lagfix was a problem for me but I heard some issued stories about it but could not remember now, sorry...

CROMI is based off ASUS' stock firmware, hence it is still Android 4.2.1 (and will likely stay that way forever since ASUS does not update the tf700 anymore). As TRIM is only available in Android 4.3 onward, Lagfix is still a relevant. As far as I know, some people reported data corruption from using Lagfix, but I personally haven't had any issue. Your mileage may vary though.
As for performance degradation, I am also quite interested in knowing why. One of the key strength of Linux over Windows is that Linux does not have this performance degradation over time and most Linux users will happily attest to this statement. Apparently, Google has somehow removed that strength when they made Android. Many people who choose iOS over Android will also cite this performance degradation as a factor since iOS does not suffer from this problem as well, if at all. At this point, I am just going to blame Dalvik VM for all this inefficiency. If you look at Windows Phone 8 (made by the same company that brought you Windows) and iOS, both run native machine code instead of a virtual machine and they don't have any drop in performance over time. Practically, a HTC HD7 with WP7 can still compete with current Android handsets in terms of UI smoothness and exhibit no stuttering nonewhatsoever, except when you started using intensive apps, but that is definitely a hardware limitation.

"Trim" is a kernel feature and is activated by using the ext4 mount option "discard", which has been in the kernel since 2010.
Expanding a bit on the issue at hand, I'm curious about two types of apps:
First one is twilight. It's much like the f.lux or redshift program for PCs making the screen red at nighttime, so that falling asleep is supposedly easier. Now I enjoy using this on any type of screen I'm in front of after dark, but the downside to this is that it makes both my tablet and phone really laggy. My phone (i9300) isn't as affected by the performance as the tf700 is, but I wonder why this sort of app slows the device down?
Second app is SwiftKey. I love this keyboard app for its functionality and its predictions. However not being a native English speaker, I also write a lot of Norwegian so I have two word lists installed. My issue is that the keyboard seems slow and sluggish in its response, and sometimes it takes forever to actually write something down. Is this related to using two dictionares instead of one? I really love this app and would like to keep on using it, as no other keyboard seems as good to me.

I also use f.lux on all our laptops. Never heard of twillight. I highly recommend and have used Lux Dash (location based sunset setting etc) for what seems like forever on Kindle Fire, Note, Note 2 and TF700 and it can even dim down to pretty much all black if you want it to. I never experienced any slow-down because of it on the Infinity.
Just last week I read about two apps that slow down the posters Infinity and one of them was Swiftkey and there was no mention of your dual language setting and I suspect it's not a dual language issue. I've used Danish & English (and briefly Spanish for Duolingo app so 3 at the same time) and also noticed it being very unresponsive, but haven't noticed any diffence with 1, 2, or 3 languages. Now it solely resides on my Note 2. Should be easy to test though, just by disabling one language and see if it makes a difference.
I can't remember what the other app was though. It was some post or article about lowering RAM usage by, among other things, using Titanium to change certain downloadable system apps (Gmail, Dropbox etc) into user apps and then using Greenify. Hopefully Greenify will work on this new Cromi-KK ROM I just installed, but that's on tomorrow's To Do List. Note: Greenify can only do system apps (paid version) with Xposed installer and Xposed doesn't work with KitKat.
Hope that was somewhat useful and not a complete waste of your time :silly:
Not sure if I need to create a new thread, or post here, but I'm at a loss. I feel like I've wasted a ton of money on this thing. I bought the TF700 over the Galaxy 10.1 thinking it had better specs and was going to be a great product from ASUS. First problem I had was "phantom touches" and had to send it in for repair. Now it's utterly useless. It SUPER slow, so slow that I'd rather throw it in the trash than deal with it. I've tried Clean Master, but it never seemed to help performance. I installed CROMBI-kk and it's still has poor performance. I've set the wallpaper to black (none), removed all widgets, and installed maybe 2 apps so far. I also tried LagFix but it says it doesn't have permission to modify the directories (or something like that). I've ensured that Root is enabled under Developer Options.
My old Incredible (v1) runs better than this. I really don't know what to do. It's very frustrating. I even wasted the money on the keyboard attachment but in combination with the lag, I can't even bear to use it. I downloaded 2048 and swipes are slow, and once the tiles move, sometimes it takes a couple of seconds for the numbers to merge.
Is there ANYTHING I can do? I've looked through the suggestions. Am I missing something? Does EVERYONE have this problem with their TF700? I wrote ASUS about it and basically said "since you unlocked the device, we would have to replace the mainboard for $300 (parts + labor) in order to undergo any out-of-warranty diagnostics." The only reason I unlocked it was because I've heard that the performance problems were due to the ASUS software, so I thought installing a custom ROM would be the answer to my problem.
Any idea if this is a hardware issue, or something that can be fixed in the software?

Something is not right mate.
Confirm what boot loader you are on please, which recovery and how you updated the ROM then we can get you setup so experience your tab like never before

I followed the instructions in the thread, using twrp-2.6.3-that3_Signed.zip and cm-11.0-20140322-CROMBikk4.4.2-tf700t_Signed.zip. I had already unlocked it a while back with the intention of installing a ROM but never did until yesterday, But I had TWRP 2.3.3.3 installed.
I booted up the tablet, plugged it into the computer, copied over TWRP 2.6.3 (zip) and CROMBI-kk (zip) onto internal storage. Powered down and powered back in into RCK (recovery). First thing I did was an advanced wipe, wiping everything except for the SD card and internal storage. Then installed TWRP from the zip on the storage. Rebooted Recovery. Did the same advanced wipe (x2), then installed the CROMBI zip from within recovery, pretty much leaving all the defaults for the install except for I chose Google Experience Launcher (not sure why, never tried it I guess). That's pretty much it. It installed fine, didn't seem to have any errors or anything odd. Booted up fine, went through the setup process on first boot. Setup 1 Google Account, and installed a few apps (mainly just Chrome and 2048). Other apps installed by ROM were: AdAway, Google+ (for auto-backup), Maps, Hangouts, and I installed SwiftKey. Most everything else seems to be stock.
As far as bootloader, not really sure. When I do the volume-down+power boot, I see Key driver not found.. Android cardhu-user bootloader (1.00 e) released by "US_epad-10.6.1.14.8-20130514" A03. I can get into Terminal Command from TWRP so if I need to run any commands to find out any information, let me know.
Thanks for your response and willingness to help!

OK I don't quite understand your advanced wipe decisions. Also what is 2048?
You need to make sure you are at least wiping /data. It may be worth loading CROMBi-kk to microsd and doing a full format on internal which will do data and the whole internal sd - it'll take about 90 mins+ so nmake sure you have enough juice.
The will eliminate any remnants and left overs.
Your bootloader *should* be fine although it is slightly old as the latest one is 10.6.1.14.10 but I don't think that causes any issues. Also make sure you choose _that's kernel in the installer and it doesn't hurt to disable journaling, disable fsync and enable the 2 GPU options.
Finally after it boots go to settings, about tablet and click the build number 7 times to enable developer settings. Then go into developer settings, enable power menu, root and set your 3 animation settings to 0.5x or zero. Last but not least change the runtime from dalvik to art and then let it reboot.
Let it settle. How does it feel now?

In the past, I've read to do multiple wipes, but the items I'm wiping should be all except the SD_CARD and Internal Storage. 2048 is a little number game: http://gabrielecirulli.github.io/2048/ (https://play.google.com/store/apps/details?id=com.digiplex.game)

I'll make a note of this as well when I go back through this. I'm not sure where I had the choice of kernel in the installer, but I'll make sure I choose _that's. I don't know what those other options are, but again, will keep an eye out for them.
