Currently running a custom ROM (1.55.605.2) and would like to change to another custom ROM that is 1.54.401.5
Are there any precautions to take when going back? Do you just do the normal wipe (factory reset, wipe cache partition, and wipe dalvik cache) and then install ROM?

You probably didn't do a full wipe. You need to format the data, cache, dalvik cache and system. Everything but the SDcard.

I Did That Three or four times and it still doesnt change....All it does is a factory reset on my phone
If I want to update my MIUI rom, can I do it by only removing cache only or do I have to do the factory reset?
Only cache and dalvik cache (advanced-->clear dalvik cache) is needed. If you're running 2.3.3 or 2.3.4 it's a good idea to do a full wipe before upgrading to 2.3.5.
Remember next time that you only need to wipe the caches and simply flash the zip. Easy peasy!
- If you want to flash a new ROM, then you'll need to do a full wipe.
- If you only want to upgrade from 1.x to 2.x you only need to clear cache and dalvik.
- If you want to upgrade, but the upgrade includes jumping to a new version of Android (2.3.3->2.3.4->-2.3.5 etc.) then it's a good idea to do a full wipe. It's not needed, but again, it's a good idea.

i personaly never do a factory reset or full wipe unless its recommended by the DEV. this way all my settings and aps are saved and still in their respective spots when switching over. most of my experiences are trial and error based.
just remember always NAND backup before you do anything. its just a android life saver. this way if something doesnt workout you just go back and start over

Thats what I thought. Thanks for the answer.
how much wiping is necessary on the nexus s when flashing roms and kernels? i've had a habit of wiping data/cache/dalvik 3 times each from my epic days when it only had a broken clockwork recovery to work with. is that a recommended procedure?
i also see that when you select wipe data/factory data reset in clockwork, it wipes cache. does this make the wiping cache step unnecessary when installing a new rom?
one last thing. . . every time i wipe dalvik cache the prompt delivers an error. is this normal? is anything actually being wiped?
thanks in advance for your help

Use dalvik-wiper.zip from morfic to wipe the dalvik on your Nexus S.
Steps to flash a rom, kernel:
wipe cache
wipe dalvik using dalvik-wiper.zip
flash rom/kernel
fix permissions
If you're having any issue, boot loops, wipe data.
wow i can't believe i went this whole time without ever actually wiping the dalvik. . . heh
thank you! armed with this info i couldn't resist the itch to do a clean install of my favorite rom/kernel
Hey, I'm currently on MIUI ics. I know I have to wipe/factory reset everything. But is it safe to flash on the current CWM? Or do I need to update it or something? Do I just flash the new JB rom like I would switching from MIUI to a stock ics rom? I'm a noob, sorry if this doesn't make sense.
What version of CWM are you running?
You should be fine, but it never hurts to check. You flash a JB rom just like any other. Wipe wipe wipe and flash.
The whole wipe wipe wipe is completely unnecessary. One wipe is sufficient and any additional won't do anything.
It's like saying that unless you wipe exactly 3 times the Android Gods are going to demand a human sacrifice for your phone to boot.
lol i think dvorak meant wipe cache, wipe dalvik cache, wipe data (wipe wipe wipe) but that's my take..
anyway, if you can flash MIUI ICS with whatever CWM version you currently have, you should be able to flash other JB ROM. Nandroid as always.. Goodluck!

This is what I did :
1. Boot into recovery and perform a nandroid backup of my MIUI installation.
2. Wipe.
3. Flash XenonHD 9 JB ROM + marmite 4.2 kernel.
My phone is running really smooth now. Good luck.

Yep, that's it. Of course wiping everything 3 times would be unnecessary.

if you get a cluster f*#@ of problems then clean install. It isn't that hard. Use Titanium Backup and good to go.
In Recovery:
1. wipe data/factory reset (this formats /data, /cache and .android_secure on sd)
2. format /system, /boot
this leaves you with only bootloader, recovery and radio...dalvik-cache resides on /data, so it's gone already.
3. flash rom
4. gapps & custom-kernel (if needed). No need to let the phone boot & settle before flashing them (most custom-kernels have a script that automatically wipes /cache & dalvik during kernel-install)
5. reboot
6. Run TB -- restore missing apps with data --1st option under restore
just updating rom:
1. flash rom-zip
2. wipe /cache and dalvik-cache
3. reboot
Do this before reporting any issues on the thread since the problems are often related to this and not the ROM or kernel.
when i flash a rom i always wipe cache, factory reset, and wipe system. those steps will erase everything from the old rom? any custom kernel? i know it does not do anything to the radio. what else doesnt wipe? what does it wipe? i am soff 1.09
wiping everything in custom recovery does not wipe the kernel ie boot.img. it also does not affect any firmware related things, it only wipes rom related things like cache,data,dalvik,system,sdcard
