Folks,

Just make sure you format the /system partition before you install any new ROM. CWM > Mounts and storage > Format /system. The new ROM contains all the system files you will need, so you don't want any left over from the prior build, unless you are doing an upgrade. Some ROM install scripts will do this for you. Others won't.

Next, wipe (format) Dalvik cache. This is where the dex files from the apps are built when the system boots (if not already present) and ones that don't match your executable system and data apps will cause you problems (this is what causes the "Android is upgrading" message at CM9 boot after a Dalvik wipe). So, whenever I install anything, I wipe dalvik. It's a good habit to get into.

Just fyi, dalvik-cache is a directory in the /data partition, so when you "factory reset" (wipe or format /data), you automatically wipe dalvik-cache too.

The /data partition only needs to be formatted (wiped) when changing between ROMs with different data formats - i.e. GingerBread to CM9 or reverse. Always read the ROM instructions...

The /cache partition usually only needs to be wiped if you are changing applications. A new ROM may have different applications or versions thereof, so it doesn't hurt to do it, and can cause you less grief down the road...

If you follow these guidelines, there will be no need to wipe anything more than once.

I think most of you know this already, but just in case... :fingers-crossed:
[Samsung Galaxy Exhibit 4G] Seminoles:
That is what I'm saying I did the wipes and changed roms like the op says but after I login and uncheck everything by the time I get back into settings there checked again and something is syncing it's like the GB and CM9 keyboard were mixed. I don't know how to explain it all there backups were missing up my stock install which I never had a problem before.

Had to do the cache wipes after install just to get market to down load.
[Samsung Galaxy Exhibit 4G] strtkempo:
A wipe is a wipe is a wipe. Titanium backup and factory reset flash and done. Having issues after flash wipe cache. I'm a veteran flasher one wipe is all you need!
[Samsung Galaxy Exhibit 4G] ricedragon:
Doesnt romwipe take care of the required wipes?
[Samsung Galaxy Exhibit 4G] jgrinst1:
Yes, a ROMwipe will format the 3 basic partitions: /system, /data and /cache and the extended partition on the sd card if you use one. You could do this every time you did an install but you would find yourself rebuilding all your user apps and data endlessly...

For most installs, and certainly a new CM9 build over an old one, a wipe of /system, /cache and dalvik cache will do the trick.

For people still using version 5 of cwm, I've found Appextractor from the play store to be useful: https://play.google.com/store/apps/details?id=com.handyandy.appextractor. Note that this currently does not support cwm 6.
[Samsung Galaxy Exhibit 4G] Kamatari+:
Is it possible because certain applications and settings are syncing with Google servers that it is causing you to experience these issues?

Is it possible that you may have not done a full rom wipe?
[Samsung Galaxy Exhibit 4G] Seminoles:
This what I'm trying to say I did the full ROM wipe in CWM 2x and other wipes 2x even factory reset 2x reason why going from CM9 to stock odexed 2.3.5 to see if the stock root zip would work on it since it was made for 2.3.6 and not tested on 2.3.5 yet while trying to move apps to SD card got (failed to move app) popup so back into CWM mount sd card and then format back into ROM apps now on SD card no problem. Now Google market will not update to Google play tried clearing cache and data in app no go so back to CWM wipe wiped the caches now it updated. So this is telling me like older windows computers the hard drive is getting old deep format 2x good to go. Now installed stock ROM logged in unchecked backup and restore before the setup wizard is done have lunch come back well the ROM is setup just like it was a year ago same wallpaper and settings as then not downloading apps as market will not download again.

Why am I writing this not to get into a debate on the ways to do things or make anyone mad, just to though out a thought some one might come up with a reason some people have no problems like i did when I first started with jocala's ROM's and the other ones he listed all are great better then stock but now I'm having problems something is going on in the background. Who knows might be ICS is more cloud oriented then it needs to be and getting mixed in with the other ROM's all I know is that after forcing Google not to backup or restore 3x I'm back to everything works as it should be even Samsung keyboard showing letters typed in little popup and predictive text.

Am I still the only one having issues with SMS notifications? It seems kind of random as to when I get a notification. Sometimes I get one for every text, then sometimes I only see new texts if I go into the app and check manually.
[Samsung Galaxy Exhibit 4G] netbuzz:
So you've been wiping multiple times for many years now??? I'm just saying because I've been around since Windows 3.1 through every release, also bunch of Linux distros and never ever have I heard of a need to format a drive twice because the first time was not good enough. That goes against the meaning for a format function itself.

What is this backup you are referring to? Are you restoring from Google when you first login to a new ROM? You need to not do that. You need to backup and restore your apps with Titanium or a similar program. And even with that you only restore user apps and data, not system.

You really need to step back and sort out the basics. Somewhere along the steps you're making a mistake. It really all works just as designed. I just went back from ICS to Rebel on Exhibit last night in 30 minutes, and upgraded to another AOKP nightly on my Nexus this morning in 15. Rooted and installed CM7 on Nook Color in under 60 minutes last week. Doesn't matter what the device is, the process is simple, quick, no problems.

Sorry but I just get irritated seeing 1000s of posts and half of them are made up conclusions and inaccurate info, everyone all of sudden is acting like an expert, and people asking same thing over and over. Well, they need to, how can anyone be expected to read all this and sort it out? Maybe that's how it has to be since we don't have our own exhibit forum on xda and must pack all the info into 6 threats.

For those of you having issues with chargers (or that external battery pack I saw someone mention), the problem is that the chargers are mostly configured to work with Apple products since they're so popular. They do this by using resistor networks on the data pins to let the device know how much current it can draw.

I fixed the problem for my phone by making a charging-only cable from a spare cable. To make a USB charging cable, open up the middle of the cable and short the two data pins together (usually white and green) on the Phone (micro USB) side. Leave the data pins floating on the charger side so the charger doesn't get messed up.

Pin Signal Color Description
1 VCC red +5V
2 D- white Data -
3 D+ green Data +
4 GND black Ground

This worked for me, my phone now charges on every charger I've tried. Don't blame me if it blows up your phone. :)

I haven't tried it, but maybe a cord like this would work if you don't want to build your own:

Just installed the newest version of CM9. I setup all my gmail, yahoo, hotmail, and exchange server as push and all my other programs just like my previous installation of RebelROM 3.0.7 which seemed flawless at 2.3.6, but it seems like CM9 is super super laggy to the point where the OS things the app isn't responding and asks me to wait or force close. Google Now is super slow...when I tap it I get a white screen for about 5-10 seconds then sometimes it loads. Have I done something wrong? Prior to installation I wiped everything that could be wiped in the recovery menu at boot.

I'm going to use ROM manager now to fix all permissions and see if that works. I'm sure CM9 isn't this bad because I don't think it would be released with performance like what I am feeling. There is a fix...I know it! I just have to find it. :fingers-crossed:
[Samsung Galaxy Exhibit 4G] afwolfpacked:
It just needs memory tweaks and I preference v6 and now use chainfire 3d in conjunction. System s smooth as silk here
[Samsung Galaxy Exhibit 4G] a0b1c2:
Hi,

I too am a RebelROM convert. CM9 is slower than RebelROM but far more packed with features. However, it's not as slow as you're seeing. Make sure you're running with the latest bits because previous versions were slow: cm_9_20120814_UNOFFICIAL_ancora_tmo.zip

Now, I haven't tried to do any of the Turbo'ing stuff so that may be next on my list to get the "smooth as silk" effect! ha!

Cheers!

-pablo
[Samsung Galaxy Exhibit 4G] rovert:
I did download and install that ROM, thank you. :) I'll go through some more testing and see how this goes. I am confident that CM9 quality is up to par with the quickest of ROMs. I don't really see the extra features that RebelROM had unless they are mostly transparent. All the major apps I use are the same as well as the basic functions of the phone. I just got this so I can use Google Now and have a trusty digital companion but it's a little too slow right now to be useful. LOL. Is this the effect of a single core CPU?
[Samsung Galaxy Exhibit 4G] a0b1c2:
Howdy,

If you look at the settings offered between RebelROM and CM9, you can note the difference. Also, CM9 has far more eye candy than RebelROM.

Now, with respect to performance, why is it not as quick. This I do not know. One of the things I do is Performance Tuning so I'm not keen on going on "feeling" (e.g. "wow, this release feels more _snappy_"), I need hard data ... and I don't have anything to present ... plus, I'm a newbie on these devices (but not to Linux/Unix).

Cheers,

[Samsung Galaxy Exhibit 4G] netbuzz:
Yeah, afwolfpacked is right. See Rebel ROM already has the V6 settings integrated, so it helps the system deal much, much easier with the little amount of RAM. Also, ICS handles memory and background tasks in a completely different way from Gingerbread which is good for devices with more RAM, but actually worse for the Rebel. So look in to that V6, I was only 75% successful with it myself, but even that made a difference.
[Samsung Galaxy Exhibit 4G] 954wrecker:
I like the extra cm9 features, but the few programs I use most often simply run smother on rebelrom. I have noticed with each release cm9 is getting smoother
[Samsung Galaxy Exhibit 4G] a0b1c2:
Dang, that's what I need ... another little side project. I hate you! Just kidding. :)

When you say you were only 75% successful, what do you mean? This way I'll be prepared.

Have a good weekend folks ...

---------- Post added at 06:09 PM ---------- Previous post was at 06:08 PM ----------

The above is very true and that's why on the last (well, minus two rev's ago) revision, I switched over to CM9 (deleted my backup of RebelROM)

[Samsung Galaxy Exhibit 4G] afwolfpacked:
In v6 set up with all options it ask to do. Reboot check to see setting stuck then enable nitrolag option. That is biggest performance noticeable change you will see. V6 will allow better memory management thus less fc and I have yet to get one. I now use rc11 test 4 version installed via terminal editor.
[Samsung Galaxy Exhibit 4G] Crow550:
If the kernel gets updated to support Battery Monitor Widgets USB fast charge (which also allows charging of outlets under 2.1amps) then I believe it it should work just fine?
[Samsung Galaxy Exhibit 4G] netbuzz:
The new V6 version has somewhat of a wizard built in. Because it's ICS and certain setting are read from different files than previous ROMs, there is a step where you upload one of your files and download a replacement. File is called services.jar. I never could get this step to work right, though others here like wolf had success. But as far as I got was quite an improvement. In the end my wife got pissed off and made me put rebel back on.

[Samsung Galaxy Exhibit 4G] shakatu:
Yes. I tried for a while with V6 turned off and the phone would often go to a crawl making me want to throw it across the room. Now I turned V6 back on and am trying out that Nitro Lag... Seems to be running great again.
[Samsung Galaxy Exhibit 4G] rovert:
Where can I find out more information about this V6? I did a google play search but that didn't get anything...I feel as though I'm the only one who doesn't know what/where/why V6 is...LOL.

Two hours ago I took my phone off the charger at 100%. Now it's at 57% with mA usage from -7mA to -474mA. Average temperature is about 35C using Battery Monitor Widget. Sometimes it would take 5-10 seconds to load after clicking the widget icon (along with any other program bringing up the "program not responding - wait/close" dialog box) and right now it's almost instant. I'm finding WiFi signal is the pits as it can't maintain a reliable lock from less than 50 feet away to the floor below and over one room in this wood framed house.

Using CPU Spy my phone would go into Deep Sleep mode a majority of time with RebelROM. I'm finding in this past 2 hours the majority of time is spent at 1024MHz is 13% and 245MHz for 80% of the time. I'm feeling as though when I turn off Syncing abilities the OS speeds up but turning it back on now and playing around has not shown any slowdown thus far.

Something is truly up because if this ROM was functioning like this with the majority of users, CM9 would have a nasty reputation. If even one person has some extra knowledge to pass on to someone who is willing to learn, I'd love the advice to make ice cream sandwich sweet again! :)

No offense to anyone as I believe one wipe actually does the job. However I do know when I uninstall apps there are still traces and parts of that app that remain on the phone. I have never examined a wiped partition to see if there are any remnants left over. I do find it somewhat ironic that we can all install the same rom and have totally different problems, all of us claiming we did a full wipe. LOTS of people who having been doing this for years longer than myself swear there IS a need to do multiple wipes... SO call me superstitious but I'm going spend a WHOLE extra 3 min. and do a few extra wipes. So far I haven't had any problems I didn't create myself playing around but I always have a backup anyway. If you don't mind excuse me while I pat my chest, tip my hat and clink the bat against my shoes, I'm hitting a home run here.

a few guys that may know more than you too, just sayin...

Download the V6 RC11 Test 4. You have to right click and "save link". Rename the file in root explorer so the extension is ".sh" (example: V6Supercharger.sh). Then go into terminal, type "su". Next type sh /sdcard/"Name of directory goes here"/"Whatever you named the file.sh". Hit enter and then hit "y" for everything you are asked to do. The rest will take care of itself.

I didn't have much luck with an earlier version so I'm going to try this one. Auto Killer settings aren't "sticking" so I'm going to try this newest script. Just ran it, so we'll see.
[Samsung Galaxy Exhibit 4G] shakatu:
ArtfulDodger beat me to it! :p

Have you tried Script Manager?
[Samsung Galaxy Exhibit 4G] rovert:
Sounds confusing..LOL..I'll figure it out. :) Thanks.
[Samsung Galaxy Exhibit 4G] ArtfulDodger:
Auto Killer/V6

Seems like so far the best course of action has been running the script, and then unfreezing Auto Killer letting the extra tweaks it adds work with V6. The problem was the min free values were not sticking and reverting to system default. Now no matter what the values V6 has set will stay in place.

Hope these 2 will be a good tag team and not conflict with each other. So far things are silky smooth as everybody likes to say here. Still once again, with only 356 of the 512mb of RAM being usable, some lag will still occur. Just not enough no matter what you do.
[Samsung Galaxy Exhibit 4G] Mwas.:
I run v6 (only 50% supercharged) what am I doing wrong? The strange thing though is, wifi calling now works for my phone after not working all this time since I flashed ICS. I don't know if it has any relation with the script or it is just a mere coincidence
[Samsung Galaxy Exhibit 4G] HeavyYeti:
I'm using the latest build, and must say I'm loving this phone. These are just minor concerns, nothing deal breaking at all, merely things that'd be cool to have.

Flash kinks worked out. I.E. Torch app and possibly active flash during video recording. I ran into instances the last week where I wish I had both lol.

Phone alerts (messages, calls, alarms) being routed through a plugged in headset. Someone else mentioned this earlier....I thought it was mainly weird, not really a bother, that suddenly my music stops and I hear my phone ringing faintly through the speaker.

Thanks again Jocala. Next week when I get paid I will definitely donate.
[Samsung Galaxy Exhibit 4G] afwolfpacked:
Rerun the v6 script. Either something was not checked to allow or something didn't stick. As a side note nitrolag portion makes the biggest difference and needs a reboot anyways so you can enable it with the rerunning of the script. You may have enabled that and that might have had something to do with the wifi calling. All other portions doesn't have anything to do other than memory management.
[Samsung Galaxy Exhibit 4G] ScipioWarrior:
I had the same issue. I had to download script manage and set it to run /system/etc/int.d/99SuperCharger with the options at boot/as root. These instructions are also available in the Owner's Guide that comes with v6.
[Samsung Galaxy Exhibit 4G] Mwas.:
I ran it again a couple of times and now am at 100%. Only thing I did different was select no when it asked if com.golauncher...goweather... (something like that) was my default launcher. All other times I was select yes since I use go launcher. The other issue was the services.jar which was successfully updated after a few tries

how does the battery life compare with stock

I'm getting around 75 hours with 10% left with probably 95% of the time on standby
[Samsung Galaxy Exhibit 4G] rovert:
I'm wondering how to get this ROM to get the phone into Deep Sleep mode when it's off? I just V6'ed my phone now and I left it unplugged for 4 hours. It's gone from 100% to 86% when my RebelROM would maybe take 2%/hour. Using CPU Spy, 94% of time my phone spent at while off was 245MHz. Deep sleep is said to be unused. My next goal is to get power usage down. Anyone have any advice on that with this ROM? :)

Also how do you make the lights on the 4 lower buttons to stay on all the time. I remember it being a setting in the brightness section of my previous ROM and I'm sure there's a way to do it here.

Have any of you found a specific flashlight software that works with this phone or is it only 100% reliable in camera and camera focus mode?
[Samsung Galaxy Exhibit 4G] afwolfpacked:
There is an an app for button lights. I did read about it in a post.

For power settings go into profile and configure there.

For torch use flashlight HD it will flicker about 3 second intervals but it works.

[Samsung Galaxy Exhibit 4G] rovert:
Thanks for all the quick replies. You guys are amazing here. May I ask what you guys are getting for battery life with your phones?

I'm so used to having 24 hours per charge on RebelROM without any tweaking. I didn't do anything but restart and whatsapp'ed a few times and within 8 hours I'm at 25%. Is this normal for Ice Cream Sandwhich? It's it's supposed to have a totally new memory management system I'm not feeling it...and I'm still getting "application is not responding: wait or close" dialog on most programs. When I go into settings > apps > running programs I have 25MB left and to even get there takes 20-30 seconds when it should take a few button clicks and less then 5 seconds. I have installed V6 and it's running at 100% but I don't see any changes as of yet. Maybe my phone is just a freak and it hates being upgraded? LOL
[Samsung Galaxy Exhibit 4G] shakatu:
No, it isn't normal. Go into settings, Performance (agree to the popup), processor change CPU to interactive, minimum to 122 MHz. Now set memory zRam to 18%, Allow purging selected, Kernel samepage selected.

Another thing to try is to install ROM toolbox and check which programs start at boot, disabling the ones you don't want.

After doing these things I've found that each time battery seems to drain quickly I reboot and it goes back to normal.

Oh, I also don't have a ton of apps installed cuz I use my tablet for that...

Here to report a bug with the camera. Its not a big deal, actually a really small deal, just thought I'd mention it.

When you are going to send a picture message and use the "Capture photo" , if you use flash, the preview it gives after you press the shutter button is a pre flash photo, but the actual photo shows the flash.
[Samsung Galaxy Exhibit 4G] ArtfulDodger:
A few things about V6 after using it all day today. I have to admit, if used properly and you do your homework, it works. Last time I used it, I rushed to implement it without reading up on it. Mistake. What I found was that first selecting option 5 after letting it perform all tweaks is best. This is the 512 option. Secondly, ScipioWarrior's advice about setting 99SuperCharger with the options at boot/as root is spot on. Using the Nitro Lag nullifier however is a no no. That caused more problems than it solved, and if you read other forums most people admonish not to enable that.

I had to disable Auto Killer and I also disabled zRam. Just letting V6 do its thing without a cluster of memory tweaks will allow it to do the job effectively. I did have to Bullet Proof Apex Launcher, Avast and Juice Defender also. So far this has produced the best results, as I can run Neutron and Dolphin without a snag unlike before.
[Samsung Galaxy Exhibit 4G] SurgeRush:
My battery is a little worse than stock, but not bad at all. I mean a day of pretty low use, but I'm at 52% with 10.5 hours on the battery, which is perfectly fine for me. I plug my phone in every night anyway.
