I am currently running Jellytime R28. Since R31 have been released, do I need to do a clean wipe or can I install over R28?
If it's same rom different build, you can probably get away with just wiping cache and dalvik instead of wiping data
but better check the dev thread
BnD always asks for fresh install if you intend to report any bugs, or posting logcats etc

I am relatively new to flashing ROMs & kernels for Android. Currently I'm using MIUI 1.5.6 and would like to upgrade to the newest version of 1.5.13.
My question is, do I have to wipe data if I'm just upgrading to the same ROM or would wiping cahce & Dalvik cache be sufficient?
Before anyone flaming me I have searched the forum prior to posting and surprisingly didn't find anything useful as I thought this would be a frequently asked question.
Thanks in advance!
I never clear if i'm gonna do the same rom and it seems to work perfect. So I'd say dont it takes less time but if your worried do it. clearing that stuff wont really loose anything so its your choice really
I think you ALWAYS should do a backup, just in case something goes wrong.
You have the device at the Computer, you have the cable hooked up.
What would it take... about 5 minutes to do the backup up ??
oddball69 is right. You should always do a wipe.
Just to avoid problems
Most of the Devs will specify for each version if a full wipe is not required. If you can't find anything about it then do a full wipe.
If they directly say a wipe is not required then it's probably just some small fixes.
Thanks for all the responses.
I was going to do a backup for sure I just wanted to avoid having to wipe everything and then reinstalling and re-setting up all my apps which could be quite a pain
Depends on the ROMs used, usually the developers state if this is necessary.
It wont hurt if you try without wiping, if it makes problem just wipe and do it again.
What is there to loose?
I have just recently begun modding my G2x. I can install ROMs without any problems but I've since been interested in flashing a custom kernel. Information is sort of everywhere and what I do manage to find I am worried about it being out-of-date. Anyway, I flashed cm7.1 (the stable release) and it worked fine until it started fc-ing everything google related (something to do with sync?). I decided to try flashing kernels (wiping caches as instructed) and could never get one to work. I've since flashed the latest cm nightly (201 I think) and tried trinity with it. Still nothing. I've since read that I should let the phone sit for 10-20 minutes but after about 20 minutes it is just a black screen and nothing ever happens. It does get really hot however. Anyway I have tried flashing kernels multiple times and nothing has ever worked, same story every time. Any way somebody could tell me what I'm doing wrong? Tell me what's compatible (as maybe sorta stable) with the ROMs I'm using? HAHA and if it's not asking too much...maybe some links too? Sorry, just very new to this and very eager to learn. I just have a bit of trouble figuring out what's supposed to be compatible and where to find it. THANKS!
Start over fresh, wipe data x 2, wipe system x 2, wipe cache, wipe dalvik cache, flash cm7 nightly, dont reboot yet, wipe cache ONLY, wipe dalvik cache ONLY, flash kernel try faux123 (make sure kernel is for cm7) latest or morfic latest, reboot, enjoy ....

Thanks will give it a shot in the morning. Too much of a headache all day. Back in a useable state and I want to keep it that way for a bit haha. Will post results.
I still haven't tried to flash a new kernel... that is coming in a bit. I do have a question though... I'm interested in getting my phone in the cleanest state possible before doing anything further. I basically want my external sd cleaned up (I want to just reformat it) before flashing a rom again. What files/directories are absolutely essential to keep? As I said, I want to just wipe it clean but I'm not sure I can do that.

So just to be thorough I can safely remove the cwm directory as well? Just delete it all put my rom and kernel zips back and I'm good?

Make sure you flashed recovery through nvflash
NVIDIA NEVER AGAIN!
Tried to just flash 0.4.7 and it did the same thing as before. Waited 20 minutes before taking out the battery then tried to boot it again. Waited 20 more minutes and all it ever did both times was get hot. Same results as before.

OK that's what I was missing. Needed to be running SV. Anyway it's working now just fine. Muuuch appreciated.

Beginning 4 or 5 days ago, the CM nightlies have become absolutely unusable on my phone. Even after a full clean flash (wipe system/data/cache/dalvik), the first boot will yield multiple force closes, usually including SystemUI and com.android.phone. After a couple reboots these will stop for the most part, but flashing gapps prompts a whole slew of new FCs (pretty much every gapp crashes, along with the accounts manager).
TouchWiz roms, older CM nightlies, and AOKP build 2 all run fine. But I simply cannot get CM to work.
Any ideas?

I've tried all of the CM10 bases roms and the one that seems to run rock solid for me with zero issues so far is paranoid android, plus I like the things that he cherry picked, I'd give that rom a try as it works super smooth and fast with imo's lean kernel.

That rom actually runs fine for me too, along with anything else based on a CM before ~9/17, but I'd love to know why my phone wont run the newer nightlies.
I have had no issues at all running the CM10 nightlies, works like a champ for me. If you find out what is going on please let us know!
Still having this problem on a clean flash of the 10-04 nightly. Email, gapps, setup wizard, talk, and Play store all chain force close on the first boot.
Your forgetting to format your system in cwm mounts/storage. That's a true clean install. Double check your md5 and try again doing all you did+format system.

Hey so I have been having the exact same issue! I flashed back to the M1 snapshot and I'm staying there until this get sorted out. Weird how it's only happening to a couple of us...

Have you guys tried fixing permissions after flashing?

So do you think that we should do a full wipe then install, boot, go back into recovery then fix permissions or can we do it without a full wipe?

I wiped system, data, cache, and dakvik. Then I installed CM. Then I wiped cache and dalvik, and fixed permissions. Same issues ocurred.
Still having this problem with M2 and the new gapps after formatting and wiping and fixing literally everything.

What I would do if I were you....
Odin all the way back to stock
Re-root
Re-unlock bootloader
flash cwm
Wipe data/factory reset
wipe cache
wipe dalvik
FORMAT /system <- under mounts
rewipe
install newest cm10
install newest gapps
boot
Odin'ing back and formatting will help wipe out any remnants you may have derp'd along the line somewhere
You should have no issue with these steps. It put me rock solid every single time (along with many many others). Report back and let us know.
I've seen older threads saying that, if you're updating a custom ROM with a new version, usually you will need to clear the caches and re-flash or possibly do a clean wipe.
I have RaymanFX 0.5.0 (which will be updated soon), so I'm wondering if, for an update, I need to do a data wipe or if just clearing the caches and re-flashing is sufficient.
Thanks.
The rule of thumb for upgrading is this:
If you're upgrading within a rom (say RaymanFX 0.5.0 to RaymanFX 0.6.0) then wiping cache/dalvik cache is generally enough. I'd also suggest wiping/formatting the /system folder too, but that's up to you.
If you're upgrading to another rom (say RaymanFX to EOS4) then you should fully wipe/factory reset your device.
The exception to the rule would be upgrading within a rom that changes from android 4.1.x to 4.2.x. In that case you should also fully wipe/factory reset.
Your mileage may vary but this is what's always worked for me. A full wipe each time for every upgrade is the best thing you can do, but it's not needed and means you spend a lot more time re-installing stuff (which I'm guessing is why you are asking).
Thanks, grgmre. That's what I expected. And, yes, I was asking precisely because of reinstalling apps. After I flashed 0.5.0 and played with it for a few hours, I reinstalled most of my apps. I'll install them a bit more slowly after I flash the upgrade or a different ROM.
As easy as it is, it's actually tempting to flash and try out more ROMs.
Hi!
I installed the latest SlimBean on my i9000, I came from CM10.0. It all went smooth, but when the OS started, I was quite surprised: all my old apps from CM10.0 were still installed!
I'm not sure whether this is a bad thing or that a complete clean install is more preferable? I think it was kind of handy, but maybe other things remain as well and make the system go slower?
I followed the official steps exactly:
From another JB or ICS Rom to SlimBean
Download device_x.x.zip, slim_gapps.zip.
Enter CWM, wipe data, format system ( in mounts and storage)
Flash Device_x.x.zip***, then MUST flash slim_gapps.zip (other files optional)
*** - If the flash is too quick ( < 5 seconds or so), reflash device before flashing common or other zip files.

Furthermore: do you guys think there is a lot of battery life gain with this SlimBean OS?
Thanks.
You should always wipe data when switching ROMs

I think you forgot to wipe data which is a "dirty install" and sometimes everything will work with no problems and sometimes you can end up with countless little problems. The more closely related the two ROMs are, the more likely a dirty install will be head ache free. Just remember if you do a dirty install and end up with problems, that you shouldn't report them as bugs until you have tried a clean install (wipe data, wipe cache, wipe dalvik cache).
Changes in battery life will depend a lot on how you use your device, so it is best for you to test it yourself. I noticed that you mentioned that you have a i9000, the best place to get questions answered about that device is here: http://forum.xda-developers.com/forumdisplay.php?f=748
I am quite ashamed of myself, sorry guys. The "problem" was that Google Market automatically downloaded the apps that I had installed on a previous installation because they were "my apps" and somehow Market thought I wanted them in my fresh install :S Thanks...
