[Q] How to upgrade ROM and keep installed apps?

Since CM and Virtuous updates itself once every 2 weeks or so, I don't want to keep on reinstalling everything over and over and over again.
Is there a way to keep all my settings on all my apps AND have my ROM upgraded from CM 6.0 to 6.1?

Yes you can keep everything if you're upgrading from CM 6 to CM 6.1. When you flash from recovery, all you'll want to do is to wipe cache... you don't need to wipe the phone unless the upgrade is causing you trouble. When switching roms entirely, you may need to wipe the phone.
But I flash the nightlies all the time, and wiping the cache is sufficient.
If you are switching roms, use titanium backup. The batch operation definitely makes restoring apps and data quicker.

Same is true for virtuous. Only need wipe for major changes. If i remember right its major.minor.bugfix i forget the last one but anyway only wipe on the major updates.

1. How do I wipe cache only?
I rebooted into recovery and i saw several wipe options but didn't know which one i had to wipe.
2. I was actually already at 6.1 RV3. Is there any point at all in upgrading to RV4? Or can I wait until it's at like 6.2 or something.

I cant answer number 1. Id guess if there is an option for wipe cache then select that. To answer number 2. RC4 will be more stable then RC3 or more features at least. If you dont want to help test these then i would wait until the official stable release. Fyi 6.1 has been released you should install that one.

[Q] Flashing from CM7 nightlies to a different ROM?

Hi everybody....Ive been flashing ROMs from ROM Manager and never had problems...until I tried to flash from CM7 nightlies #66 to a leaked G2 ROM][04/28/11] TMOUS G2 Gingerbread 2.13.531.5.
I did the usual wipe cache and dalvik and proceeded, it seemed like it was downloaded but got stuck on the reboot, it was stuck on the HTC logo for a long time. I thought I bricked it but managed to get it to work by taking the batterie out and going into recovery by clockworkmod.
Is there any special way to flash ROMs from the nightlies on a G2?

You said you wiped cache and dalvik, but did you wipe data too(factory reset)? Pretty sure you need to do that if coming from cm to the stock tmo leak. Could be wrong but sounds about right

that is right anytime change roms that are not linear to the same dev, it is best to wipe all, data/factory/cache then flash rom

Hmm, I checked everything that ROM Manager suggested, cache/ dalvik, the only thing I didnt check is to back up current ROM.
If you wanna wipe all that data/factory/cache do yo have to flash it manually?

Flashing other roms I think messed up my phone lol. I just stay with cm7 now lol
Nonsense!

even if you did say to wipe /system and /data in addition to /cache, CWM is notorious for not actually formatting the partition. go into the dev section and find SuperwipeG2 and if you are switching from aosp<->sense or, as earlier mentioned, from one dev's rom to another, run superwipe before doing so.

[Q] ROM with Settings Profiles besides CM9?

I am currently using CM9 on my GNex because it has a built-in Profiles management application in Settings.
Is this feature exclusive to CM? Do other ROMs have this feature? I have tried various market apps to replicate this functionality, but none of them seem to work the way the CM9 one does.
I thought I had seen someone using AOKP and it had this in his Settings, but when I tried to Flash that ROM, I got a ton of errors on reboot and didn't find Profiles in the Settings section either.
Also, as I am relatively new to Android (this is my first Android device), should I do a complete wipe data before installing a totally different ROM to avoid process errors? I am using Clockwork Mod recovery to flash ROMs and just performing the default "wipe Dalvik cache" before installing a new ROM. So far, the only ROM I am able to install/update is CM9. AOKP and Codename Android just gave me a ton of process errors after booting and were just unusable. As such, i am currently stuck using CM9, but have really bad wifi performance with it.
TIA!

Yes. Yes Yes Yes Yes. ALWAYS do a full data wipe when moving from one ROM to another ROM. You can sometimes get away with not wiping if you are simply upgrading to a newer version of the same ROM, but anytime that you run into issues after installing a new ROM please do make sure that you wiped data before posting/complaining about issues.

Thank you for your clarification. The next time I try a completely different ROM I will do a full data wipe. I assume flashing new Nightlies of the ROM I am already running doesn't require a full data wipe?
But can you or anyone else tell me if AOKP or any other ROMs have the "Profiles" feature in Settings, like CM9 does? Or is this exclusive to the CM9 ROM?
Thanks again.

I haven't seen it anywhere else, though AOKP does offer a Quiet Hours option.

THANK YOU!
Using your suggestion to do a wipe data when flashing a rom, I downloaded the latest CM9 nightly, and just installed it wiping both the data and cache.
After my initial setup and installing the speedtest app, my ping is back to normal at ~25ms and 15mb down and 2 up!
Do you always (or recommend) wipe the data even if you are just updating the current ROM?
Hopefully one of my other apps wasn't the cause of this issue, but I'll soon find out once I have re-installed everything.
Thanks again.

The ROM developer will usually state in the changelog / release notes if a wipe is required/recommended for an upgrade. Rule of thumb though:
1) Updating ROM to newer version, same Android release (ex: 4.0.3 -> 4.0.3) ==> No wipe
2) Updating ROM to newer version, different Android release (ex: 4.0.3 -> 4.0.4) ==> WIPE
3) Changing from one ROM to another ROM (CM9 -> AOKP) ==> WIPE

Interesting. After reinstalling my apps one by one, I've been running speedtest and found that Airsync/Doubletwist is the cause of my slowness. Uninstalling and rebooting fixes the speed/ping issue right away. Glad I bought this app. Not.

Galaxy Nexus Frequently Boot Looping After Reboot

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.

an easy hint may help: always wipe cache and dalvik AFTER flashing rom, mods... to prevent conflicts :good:

[Q] Flashing issue or not ?

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.
