My phone has been running super laggy lately. Shiny ROM (CDMA) 4.4.2 Rooted. I tried clearing cache and davlik through CWM. Seemed to help for a few days. I usually only wipe cache partition and dalvik before flashing a ROM or something. Without that second step, what (if anything) does this accomplish? Any chance that this temporary lag reduction is a telltale for a particular problem I should know about.
Thanks!
Did you wipe data and system before flashing your rom?

I've never found a convincing answer for your question. But from what I can tell a cache partition is probably meant to keep things the system uses closer at hand. Wiping it will force the system to create a new cache of things it needs and may possibly improve performance. However I believe the guys from google are good enough to keep a caching system that doesn't "age" (I mean it shouldn't slow down with time).
I believe the reason it should be wiped when you flash a new rom, is because a new system should create it's own cache...
Anyway, if I were you, I'd try flashing a new kernel. Personally I find Fancy Kernel to be the best. I've tried a few and they all let me down eventually. Fancy Kernel has helped in android 4.3 when my phone was getting extremely laggy with franco kernel. It was like buying a new phone.
I've recently used Dirty V that came with OmniMetal Rom and, although it was fast, it used too much battery. Once again Fancy Kernel helped with that issue and the phone is just as fast.

that's called a Force Close (FC). It usually happens with an unstable ROM/unstable app but more often it happens when you don't wipe (Cache/Dalvik) before installing a custom ROM.
Backup any important data that's not already on your sdcard, go back into recovery, wiple your cache and dalvik, and flash the ROM again. see if that helps you

even if im coming from the old fresh to the new fresh i still have to wipe
I'm not familiar with Fresh's ROMs, if you read his threads carefully I'm sure he'll tell you which version upgrades require a wipe and which don't. Usually a drastic upgrade will require a wipe. In your case a wipe will most likely fix these FCs
With the learning curve for the EVO still growing, its usually a good idea to wipe data/cache/dalvik when flashing new roms. Even updates. I haven't seen too many "No Wipe Necessary" around this forum. As long as you've got Titanium or MyBackup, wiping isnt as big of a headache as it used to be. Hope you get things figured out. Screwing with these phones can get frustrating. Dont know how many times I wished I hadnt messed with anything.
well i just wiped and reloaded fresh so hopefully this will fix everything
I am not new to this, I have experience with rooting htc and samsung devices. I have also searched, and searched, and searched with no luck on this.
However, I am stumped on this phone. I am using ODIN to flash the S/U script, I can gain root, install CWM and install it. I can load a ROM but one of 2 things happen: when I boot it up I get stuck in a boot loop, or it won't even install in the recovery.
I have a few questions / statements:
WHY am I getting stuck in this boot loop?
I am wiping cache/dalvik before I install the new ROM.
I am installing the ROM on the SD card vs the internal memory, is that why?
I got stuck 3 times in the boot loop, and I have had to use ODIN to flash my phone back to stock to start over.
Thanks in advance for the help.
If you have searched, and searched, and searched you would have realized that this is not development related.
for someone who's been around then, you should first off know that this belongs in q&a, not development.
that being said, which recovery are you using? i don't think that's your problem but a little more info would be helpful. also, which rom are you trying to use? when you're wiping, try using this, it'll wipe everything necessary. you only mentioned wiping your cache's so maybe that's it? in any case, flash the file i linked, then your rom. check the md5 on it and make sure it's a match. after you reboot, let your phone sit for 10 minutes and hopefully all will be well.

If you look in the darkside rom thread, and some of the other rom threads, you will see three recommended wipes: darkside super, kernel and darkside cache. I would suggest you do all three.

Here is a big problem as well. You wipe cache and dalvik AFTER you flash the rom. I usually do it before as well but always after. That's like wiping before you **** and not cleaning up after

I used an old version I couldn't get the latest one to work. But it wouldn't even load for me. It been a min sence ive used odin. But my replacement phone is at the house I'll pm you the steps I'll take. Everyone else try to be nice even if you think the question is stupid. Try to show some love
sorry i read wrong. i thought you couldnt gain root. as far as boot loops follow darksides wipe method it work. as far as my replacement phone rooted after first boot. my usb port is broke on my old phone
anyone know how to get back to stock with out it?
sence we are asking crazy ass questions?

Questions go in the Q&A section
To those of you who helped by answering my question, thank you.
To those of you who told me I posted in the wrong sub section, get over yourself. Especially the guy with 13 posts.
I am wiping cache/dalvik before and after.
I am using CWM from the market, so it should be the newest version.
Ill check out the darkside thread.
You really don't need to wipe dalvik cache after a fresh rom install, unless you didn't delete the data partition (wipe data). And you certainly don't need to do it before and after.
Wiping cache and dalvik cache is really only useful if you make changes to the system but don't want to format the data. This includes flashing themes, and other enhancements, because most of them are replacing system files. On your first boot the dalvik cache gets built. (This is why a lot of devs recommend letting it sit for a bit before using it, it's giving it time to build the cache.)
The reason they tell you to wipe dalvik cache is let's say you're installing a theme, and it replaces systemui.apk and framework-res.apk, located in the system partition. The dalvik cache is already built for these files, so in some cases if you don't wipe the cache you'll boot loop. When you wipe dalvik, you are letting it be rebuilt with the current files.
Also, while we're on the subject, another misconception I see alot of, you don't need to wipe the dalvik cache after you wipe data. Dalvik cache is located on the data partition, it's a folder there. If you wipe the data partition, you've already removed it. (Not to be confused with cache partition, which is used for different purposes. That is it's own partition.)
Been a bit confused on this. When I initially got this phone i317 (rogers), I rooted no problem, got TWRP running no problem and first thing did a nandroid. Flashed the older stable version of paranoid android 2.54 (i believe) which is based on 4.1.2. No issue what so ever.
As well before i go on, I've been rooting phones a while. Never bricked anything and definitely know the concept of the search button.
After running PA for a day or so and not seeing too many people having issues flashing roms on this phone i flashed another ROM (unfortunately I cant remember which one, but it was one of the popular ones on xda) TWRP had no issues flashing.
When the rom booted and android itself loaded i then had three FC errors and android rebooted. Ok thought it was a bit odd. Said screw it and recovered a backup. However any backup i flashed the error continued. Tried flashing the original PA rom again, the issue continued. Eventually had to reflash in odin the original rooted stock rom.
As you have read this issue has been resolved. My question is what happened? Is this a common problem with this device? Is it perhaps an issue going between 4.1.2 and 4.1.1? Is this just an issue with the devices internal memory? I have yet to read anyone having similar issues, however am not on xda as much as i used to be.
I am really just making sure that i am not missing something obvious or if this was simply an isolated issue before i sample some other ROMS floating around this site.
Any input is appreciated.

Did you happen to wipe data before you flashed the new Rom? I have never experienced any force closes while flashing roms.
This is what I usually do when going in between roms.
1. Wipe data/cache twice
2. Flash rom
3. Usually start to hate the Rom after the first minute.
4. GO into recovery
5. Wipe data twice
6. Restore from CWM recovery.
7. Fix permissions (just in case there was a mixup (usually helps resolve force closes)
Hope this helps. If you do happen to wipe data then I am as lost as you are . Maybe try fixing permissions? I am fairly new to android but I have been picking up modding it pretty quick.

I don't think this is a process thing.
I always full wipe before a new rom, clear dalvic and such. This was something different.
Have been stuck in many a bootloop, but never one that caused rebooting when a recovery is flashed or a different rom for that matter.

Some ROMs require a factory reset wipe on top of the cache and dalvik wipe. I've used PA, and when I did the standard cache and dalvik wipe to PA from JellyBeer, I had repeated FCs, which namely was System UI. Even a nandroid restore after a cache and dalvik wipe had no effect. I was still getting the same FCs. I ended up using all four wipes with TWRP and a clean flash of JellyBeer, then a nandroid restore, to get rid of the FCs. Of course, several of my settings got wiped, including DPIs. Some ROMs just don't play well with other ROMs without a factory reset after the cache and dalvik wipe, which gets rid of your settings for a clean flash.
The other possibility is you're going between 4.1 and 4.2 ROMs. 4.2 ROMs create a new directory that puts all your files into due to multi-user login capabilities. Switching to a 4.1 ROM would certainly cause confusion within the phone without transfer the files back outside of the new directory.
Thank you. That was exactly what I needed to know. Was a scary issue the day after I purchased this phone outright lol. Not an issue I've experienced before with any other device.
Cheers.

So I've been flashing a couple of different roms this week like Carbon (based on AOSP), PACMAN (Don't know what it's based on), Rootbox (based on AOKP) and Slimbean (AOSP) the method I've been using to flash is wiping data/factory reset, wiping cache/dalvic cache, flashing ROM & gapps, flashing NexusLouder mod, flashing custom kernel, advance restoring data only then rebooting. I think this could be the cause of the boot loops. Or... it could be the function implemented in Carbon which doesn't require you to constantly flash gapps anymore since it backs everything in /system/apps. Anyone know what the cause of the boot loops are for sure?
Extra details - I started using this method ever since I was on AOKP which was my first custom rom. Then a few months ago, I moved to Rootbox, then Carbon, then I tried out PACMAN for a while then reverted back and just today I went back to Rootbox for a while, then I tried out SlimBean and ever since today, I've been getting random bootloops when I restart my phone. It doesn't happen every time I reboot my phone but when it does, clearing the cache solves the problem temporarly and I also had to do a full restore of my nandroid a couple of times today.
Also, I use this method because I have over 75 songs on my playlist which I spent hours creating and I don't want to start all over again. I also don't want to set all my rom settings again either.
Reduce any OC
Undo any Voltage mods
Disable any apps that alter how the system behaves
Disable all apps and enable one by one until you have an issue
You get the idea.
Definitely want to avoid restoring data from another rom and flashing audio mod. If after flashing a new rom you still get the random reboot then you can narrow down the problem.

Hi, in the last minutes i've flashed the 2.7 build of LiquidSmooth Rom from the Paranoid Hello Halo rom... I've done the prcedure like XDA said : Wipe Wipe Wipe (cache, dalvik, system) Flash Rom Flash Gapps. It booted fine but all my apps that i've had on my previous rom was still there... all of them. The most disturbing is my settings were also like I've left them ( disabled pie wifi etc) also my Google Accound was already setuped and good to go. Is it a new feature from flashing 4.2.2 rom to an other 4.2.2 rom ? I've never seen that before. I've also rebooted to make sure it wont boot loop on reboot, and it booted like a charm!
Any clues ?
Weird, never seen that before. Tell us what recovery you have and exactly what you are wiping. Can't think of anything else at the moment I'm sure others will chime in.
Sounds to me like you're not wiping /data. This is where your apps and setting are stored and unless you factory reset using stock recovery, deliberately wipe/format /data, or flash a Rom that wipes it for you, all your apps and settings will remain.
Seems like normal behavior to me.

Ya I re-read it and he just wipes caches and system, definitely need to factory reset lol.

Got it that's why. I was sure wiping system would wipe data too. But do you think its dangerous to not wipe data? Because actually my ROM is rocking right now without issues? Should I reflash it for safety?
It just depends....
It's always best to start clean, especially if you were having problems. But if you want to keep data intact, you should be ok as long as you don't go to an entirely different rom, base, or build.
If you are updating to a newer version of the same build, you're fine. Also if updating to a newer build/version you should be ok, but may have a few hiccups.
However, anytime you go backwards (4.2.2 to 4.1.2) you should wipe it all. The same is true if you are moving to a different base, such as CM to TW. Keeping your internal sdcard data is usually ok, but sometimes it can cause some issues.
