Is it 100% neccessary to wipe before updating a rom if its the same rom just a different version? Like I have cyans 3.6.8.1 and want to go to cyans 4.0.1
I'm just looking for some clarification on this matter. I know when you switch roms you want to but I haven't really seen anything concrete on upgrading roms. Any help would be appreciated
No, no, no.... you need to wipe when you use a bathroom, not when you flash software
People will hate me for this but... here it goes
We wipe to avoid problems with the new rom. We DO NOT know if we will have problems, good chance that we will NOT. I never wipe untill something goes wrong, and I was just fine for last 14-15 flashes.
Here's another way to think about it.... do OTA updates wipe your phone? Didn't think so.
Flash away. If you have problems then, and only then, nand back to your previous configuration, wipe, reflash. Don't wipe after flash... Cyan's roms don't like that AFAIK.
Good luck.

I heard somewhere that it's best to wipe when going from HTC rom to Google rom and vice versa. I know that for cyan's roms that if you rarely have to wipe (I had to wipe when trying out 3.9.11.*), but for the most part you won't have to (went from 3.4.6 to each update until 4.0.1 without wipe)

At this point..the only HTC roms we have are Hero and that's a whole another story. Not only you have to wipe but also reformat your sd. Big mess... not worth it IMHO. Your mileage may vary.
Thanks for ppointing this out though...
Personally, I wipe, then repair ext filesystems before I flash a new ROM. The only time I don't is when I'm updating a ROM that I have, cm x.x.x to cm x.x.x, in hich case I'll just repair ext's then flash. But, when in doubt...
Original question(s) seem to be solved.
Closing thread
I have a rooted cdma sprint hero and i hear every once in a while that there are some left over stuff that may cause problems with new roms. Now i was wondering what would be the best way to wipe to make sure that there is nothing left over from previous roms.
This is what i do;
1 back up pics and music from sd card
2 format sd card
3 put new rom on sd
4 flash into recovery
5 wipe all that i can cache devalk (sp) etc
6 Run moduler remover
7 Falsh rom
8 Flash kernal
I was also wondering if doing this removes any kernal that i have put on there or am i just adding them on top of each other?
Sorry for such a noob question but i would really like to make sure that my phone is running how the guys making these roms intend them to run
You're being real thorough for sure! LOL! I just boot into recovery and wipe dalvik, cache and ext. I t really depends on how different the new ROM is, as incompatible files are the problem.
Sorry for putting in the wrong thread i wasn't where i thought i was and im not sure i am where i thunk i am. if this needs to be moved feel free
Switching between ROMs all you have to do is wipe data/factory reset and wipe dalvik cache. That's it. No need to reformat your SD card..
what about if you use ap2sd?
Looks as if wiping/resetting the device directly from Fastboot is starting to become fairly popular as well. May want to give that a go...
-Reboot to Fastboot
-Wipe/reset
-Reboot to Recovery
-Flash ROM/Kernel
-Reboot device

If you use apps2sd, that's what wipe ext is for. I actually forgot to include that in my previous post.
wow didn't know that thanks
Just making sure, you're talking about apps2ext, right? Not the built-in froyo version aka apps2fat?
Yes I am not running froyo ... yet

Since the topic is up I have a question on my own. Are all the wipes necessary when I flash one rom and then nand restore to another?
I just Nandroid, flash and pray the new ROM works I may do a Dalvik wipe now and again. Fingers crossed I have had no problems so far, except when I figured there would be one

See my post above...Some do, I don't, and the last few days I have flashed, Nand, reflashed new ROMS, themes, etc while messing with CM6.1 and have not even done a Dalvik wipe...that's just my style though Is it necessary? I would say no, others would say yes...
However, I do have a collection of working ROMS on my SD from Nand all set up the same way that were done correctly (i.e. proper wipe, etc.) with different themes I can go back to if need be.
Hey I have a question I am on Darkyy 9.3 and have flashed to stock before numerous times and have a Download Mode Jig always handy but I have been hearing and reading recently that with good ROMs with the new install script that you can just flash ROMs over each other if you wipe data and cache and dalvik cache and if you get in trouble just flash to stock.
The reason this interests me is because im a build 1011 and its super annoying because I have to flash to JH3, then Root, then apply 3 button fix.zip sometimes if the 3 buttons dont work, ROM Manager, Quick Boot, JH7ota.zip, then flash the next ROM.
I am willing to do this but I am feeling lazy today and wanna try out Serendipity so Im asing YOU do you think i'll be alright if I flash Serendipity JS3 over a JS5 Darkyy 9.3?
Also one more questions related to that is Serendipity users does it overwrite your Kernel and modem when flashing? I have Suckerpunch and JL3 and am wondering if I should disable lag fix-->Install latest Speedmod. Or would the ROM script just overwrite that.
Finally a question that was posed to me today from a user that doesnt flash to stock and hasnt had a problem that really made me think that what really is the difference when using Odin which installs an unneccesary bootloader and ect going from a JS5 base to a JH3, then using CWM to go JS5 to JS3? Wouldnt it seem logically easier and safer?
Any input and comments about your experience will be GREATLY appreciated.
you can use odin1click, or odin3...
since you have a jig, flashing to stock is not a big deal to you.

he cannot use odin 1click since the build is 1011. it will brick the phone, for sure.
I Odin3 back to stock, but I'm also on the safe side. I have heard more and more people flash over the old ROM with using Odin though.... I figure that it only adds a few more minutes to the overall task, so why not?
always flash stock imo
just best to go to stock , flashing over has created small bugs for me ..., i do this even for common builds or updates, even though the Dev's work hard to make them upgradeable...i still do .....and if your courageous,,, its good you have the jig or a 1007 build
My personal choice is flash to stock if the roms use different kernels. If the kernel is the same, even different revs of same, I don't bother with stock.

I always flash to stock and go through the whole process. I find it less buggy and the mental idea of a clean slate allows me to address issues solely on that rom and not past components.
It's sure as heck faster to flash to stock than to read through 1000's of posts to figure out if it's a good idea or not when I don't know as much about it...
I'm still new to the flashing ROMs world, but I'd rather be safe than sorry at this point so I go back to stock whenever I switch.
Ive now just wiped data cache and dalvik cache, and flashed over 4 ROMs in the past week with ZERO problems.
That being said im always safe I do it at home with my jig and odin ready on my PC.
But i actually havent had a single problem.
Darkyy-->Andromeda-->Paragon-->Serendipity
Hey all. Just joined the forums a few minutes ago and I have a burning question on why it is necessary to flash back to stock with odin before you try different roms. Why can you not just boot into clockwork, factory wipe, wipe cache, wipe d cache and then simply load the new rom from sd? The reason I ask is because I have been bouncing between cognition and paragon for about 2 weeks now NOT using the method of flashing back to stock 2.1 without a single problem. I'm sure there is a good reason flashing back to 2.1 before trying new roms, I would just like to know why. I was able to preform a stock wipe using odin3 one time last week (just did it to make sure the phone would do it) it just seems like a really long process, but I'll start doing it that way to avoid a brick.
Thanks
to be safe, and some roms mod files that others dont, some roms depend on apps and files in the stock rom that might be different or not there at all in other roms.
long process? extra 5 minutes when you get used to it. if you are ATT use ODIN ONE CLICK to restore stock 2.1 (hint: it takes one click)
For the most part, you don't really need to flash back to stock. It used to be a bigger deal to flash back to stock because some of the Roms would intervene with each other and mess things up. It is still recommened for a clean flash, but I rarely do it and my flashes work great.
EDIT: @Trusselo: damn it! Second time someone beat me to the answer tonight!
HAHA
and forget ODIN ONE CLICK !!
i keep forgetting about this

I have been trying roms weekly since November and have only needed to flash to stock twice, after failed flashes caused by my lack of patience. YMMV of course

It's not necessary and not even a good idea. Also, why wipe cache and d-cache when the install script does that?

ROMs don't mod or use any files which are on the phone prior to installing them. All the files on your phone after the install were in the CWM flashable zip file. Any ROM cook would be stupid to do otherwise. The exception would be no-wipe ROMs, but you would never flash to stock before using one of those.
Ive also wondered this as well and talking to guys like opcow, and a couple other Devs such as MikeyMike and a lot of guys at the Andromeda IRC they all agree that you should be perfectly fine now as long as you wipe everything before you flash.
I may try with Andromeda when I get home because I have my PC and Jig there just in case but still may try now. But also tlaking to a lot of users that they dont even do it anymore now because of the install scripts and as Opcow said if you think logically its technically safer.

Actually thats not true at all.
If your a build 1009 and under you can use the one click. Although the build 1008 sometimes have problems.
But for the Build 1010's and up (like me) you have to use Odin3 and take a good 30-40 minutes just to get to JH7 because half of the time I lose my 3 buttons then have to push the 3 button fix over via ADB. I have gotten use it and its a pain in the ass.
And the time I listened to someone that says ALL ATT people can use the one click it completely ****ed my phone and if I didnt have a jig my phone would have been completely screwed up.
Im not trying to be rude im just saying I saw a post very similar to that a couple weeks ago and it came very close to completely bricking my phone and reading posts here now saying they have the same problem and if they dont have a jig they just got a 200 dollar paper weight.
Sorry for getting off topic back to topic today Im going to flash Andromeda over Darkyy 9.3 and wipe data cache and d cache in CWM and see how it goes although everyone and even the devs and a lot of users now a days say it should work perfectly.

+1 Guys if you don't know exactly what to do/suggest please don't say it. I'm not trying to start a war, but a wrong suggestion can easily soft or hard brick someones phone. This is a forum, so no one can stop you from saying things, but think about if it happened to you? You would be pissed!
Anyways back on topic, what model phone do you have, because having a 1009 model phone makes flashing and going back to stock (usually) so much easier. But then again, I rarely use odin because all the roms are compatible for the most part.

I've never used ODIN because I haven't wanted to try to run it from GNU/Linux in a virtual box.
I just wipe and flash from clockwork like the op. Been flashing roms for a couple months now, never had a single problem. (except when I noobed it up by trying to flash back to a nandroid backup via Rom Manager. Even then, didn't need Odin to sort it out).
If I ever run into a problem, then I'll try Odin, but I'm waiting to cross that bridge till I come to it.
To prevent exceptions or troubles from the version you already have... so everybody comes from the same rom, understand?
I flash to jf6 because that's what I have been conditioned to do for a while. However, the few times I was impatient and didn't....no problems either.
From all the reading I've done here, the only reason to do it is for the placebo effect.
There was once a time when all the new roms were built on the unofficial froyo and it only had 3e recovery. The quickest way to get around that was to flash stock. Also the lag fixes were tricky and easily fixed by flashing stock. Now recovery is in the kernel. As long as you insure the kernal lag fix in rom A understands the kernal lag fix in rom B flash away. Nandroid backups are kind of useless they don't backup the kernal or the modem. Save odin for when things go really wrong(;~ )

I have done it both ways, and there its no difference going back to stock and or flashing over other roms. I flash often, have not got stick in boot loop in months
I like to go back to stock since I KNOW that everything has been defaulted back to normal. Just a security blanket step for me.
I flashed andromeda over darkyy 9.3 just wiping data cache and d cache. Nothing wrong. Everything worked perfect so I got to believe that if you just wipe everything it should work perfectly.
Just for safety I got a jig and odin but for now I'm saving a good 45 minutes to not flash back to stock

I've flashed and flashed and flashed both ICS and GB roms on my bionic and I've yet to find one that works. I've had more luck with ICS roms than GB, but still I get roms that the dialer is bugged and you can't hear anyone or anything when using it. My data drops every 2 seconds on both ICS and GB roms.
I've tried Eclipse roms, everything worked fine, but I couldn't hear no one on the phone unless they called me first. So I had to get rid of that one for that reason.
I've tried every ICS rom out there, gummy works the best for me, but I get data drops every 2 seconds, bluetooth (which I use all the time) works, but if you forget to leave it on you can't hear nothing on calls. And for some reason it's started doing the same as Eclipse rom is doing, I can't hear no one on the phone not even if they call me and bluetooth is not on.
I've then tried Liberty rom, and I couldn't get data working period, the phone wouldn't work either.
Did I just get a crappy phone that just doesn't like to be flashed so many times or what?
Are you wiping data, cache & dalvik when you switch ROMs? Not doing wipes is the biggest cause of ROM malfunctions. Some ROMs just don't like it when you don't wipe. ROMs are built under the impression that they're starting out with a blank /data partition.
I ran Eclipse 2.2 for a while and everything on it worked without issue. However, Ice Cream Sandwich ROMs are a problem and will continue to be a problem for everyone. To me, it's a miracle that ICS ROMs even boot up on the Bionic. The locked bootloader means that the kernel cannot be modified except by official Motorola updates. This means that all these ICS builds are running on a Gingerbread kernel.
Yea, I'm wiping everything on each flash.
When I flashed the Eclipse rom, I wiped data, cache, dalvik and everything was fine except the call issue where I couldn't hear anything but people could call me and it'd be fine.
I've had better luck with the ICS roms than the GB roms though for some reason, minus the bluetooth/data issues.
What are you using to Flash, Bootstrap or SafeStrap? I know Eclipse has been giving me minor issues, but all and all it still works. Forget about trying Liberty or even anything else unless the Dev. modifies them to work with the 902 radios. There have been some people trying out the new radio leaks such as 904 and 905, but if they ever issue a true OTA you have to FXZ back to the 902 in order to apply the update. To touch up on some other stuff you can do also is format the internal storage. There could be something in there causing those issues to happen. Before I flash a new 902 compatible rom I go and backup everything important onto my external storage using ES file explore and then format the internal using the storage settings in the system settings.
I do the wipe data/factory reset, not sure if that gets the internal storage or not. Followed by the wipe cache, wipe dalvik.
I was using Safestrap, but FXZ'd back to stock and started using Bootstrap. Right now I'm sitting on the stock rom with bloatware frozen.
