Flashing latest build of CM7

Sorry, this might be kind of a noob question, but i see build 23 is out for CM7. If i flash the new build, do i need to totally set up my phone all over again?

My last experience with CM ROMS on my G1 was that if you are upgrading to a new CM version a wipe is recommended but not necessary. However, if you do not wipe and experience problems it will be the first troubleshooting step suggested to you
YMMV on the MT4G builds, but that's how it worked with the G1

Thanks. Ugh, i didn't even think about that when i flashed CM7. Seems like it is a real PITA to wipe every time and have to configure all the settings again.

I had good success on my move from stock -> Ice Glacier (un-crapwared stock) by making a full TitaniumBackup of -everything- and then restoring it app by app (along with settings). They are similarly built ROMs, and it worked well for me with minimal downtime. You may want to consider trying that if you are just changing between CM flavors, as I would presume they are mostly backward compatible with a few fixes/features here and there. At worst it may leave you with just system settings to redo.

When i flash a new CMNightly all i do is wipe the cache and the Dalv/Cache and i've yet to have any problems. If you are worried about wiping and restoring everything. you might want to look into Titanium Backup.

thanks. I flashed without wiping and it seems to be fine. I was worried more about my system settings than apps.

Wiping the Cache and wiping the Dalv Cache will not reset the phone. Only a full wipe will do that.

To my understanding, a "full wipe/factory reset" in Clockwork Recovery will only clear /cache, /data, and Davlik cache. /boot and /system will not be touched. Some users moving from Froyo to Gingerbread have had problems with /system, and a wipe of /system (from within Clockwork Recovery or from adb) has solved some problems for people, beyond what a full wipe can do. Discussions are in the CM7 thread in the Application Development subforum.
I know, most people refuse to search for anything.

i usually wipe the Cache and the Dalv Cache when updating nightlies, but several times i've wiped nothing and just flashed the new one on top and its always worked just fine for me

I always do a full wipe when installing roms. Setting it up each time makes me think its a whole new phone which is cool.

You do NOT need to wipe when upgrading to a new version of the same ROM. I've probably flashed 10 no-wipe updates of cm7 on my phone and it's still perfectly stable, no force closes or anything.
Boot into recovery and wipe cache and dalvik cache before flashing. Give it a few mins to "settle" on the first boot, reboot again and you're good to go.
Worst-case scenario you'll just wipe and reflash anyway, and nothing lost.

CM7 Nightly Question

Hi all. I recently got my Inspire and have flashed a few ROMS, finally settled on CM7.1 RC. I want to try out the nightly route, but not entirely sure what order to do it all in. This is what I think I need to do:
Go into recovery, format /cache, wipe dalvik cache. Flash nightly 144 over my current 7.1, flash the bbmod165bBFS.zip, then juwe11 script (does this get flashed each nightly?), then reboot. Is this correct, or am I forgetting anything? Do I need to flash gapps again? I already made a NANDroid. Thanks.

you got it. i dont think you have to flash the script everytime and you will not have to flash gapps everytime. btw you dont have to wipe between nightlys just simply flash over

Thanks, I appreciate the quick reply. So I shouldn't bother to wipe cache and dalvik cache? I thought that was pretty much recommended before flashing the majority of stuff. Ok, so I'm off to flash this nightly.

I never wipe between nightlys. But if you ever do encounter problems, then wipe cache, dalvik cache then reflash

I've always wiped cache and dalvic between nightlies. I don't know if it's needed but I've never had any problems with installs. It only takes a few seconds and it's never hurts to be safe.

I flashed 144, no issues so far. Thanks to all of you for the replies. I ended up wiping cache and dalvik cache just to be safe. I know there's a change log, but has there been any changes of consequence over 7.1 RC that are noticeable?

I know the most easily noticeable is if you put a lock screen on you can disable the lockscreen. Plus from 143 on is now on 2.3.5 if I'm not mistaken which does have some slight tweaks.

Flashing a JB ROM

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.

Anyone else flashing ROMs and finding them sluggish?

I used to flash things like Liquidsmooth and my phone would fly. Now when I flash GPE or a CM based ROM, it hangs and lags sometimes. Anyone have any similar problems?
Would also be a good time to ask, will wiping internal storage in TWRP delete recovery so I can't flash ROMs?

No issues here... To answer your question... no It will remove your backups if you stored any there. Once you have installed twrp it will always be there unless you change it.

That's your whole problem right there.
You are reluctant to wipe /data? You HAVE to do it if you go from one rom to another. Also called a clean install.
If you go to the Wipe menu in TWRP and just swipe the button it will wipe cache, Dalvik and /data except /data/media/ which is where your personal files live. It will wipe you apps and their settings, but you can backup those in TiBu and restore them afterwards. Do not restore system settings from TiBu though!
Give your phone a break. Do that factory wipe I described above, then re-flash your current rom and I can pretty much guarantee it'll be night and day.
This phone is so fast - a shame to gum it up

[Q] What to wipe?

This is probably the wrong place to ask but I wanted to know what I should be wiping in TWRP before I flash a new ROM. It's been a long time since I flashed a fresh ROM (I'm on CM11S for quite some time) and I can't remember what I wipe to give myself a clean start.
Thanks

Depends what you mean by clean start, if you mean you want fresh out of the box experience (no apps, no pictures, no anything etc) goto advanced wipe and select everything apart from USB-OTG.
If you want to retain all of your media (pictures, videos etc) the standard wipe in TWRP should cover you (wipes dalvic, cache and data), you don't need to wipe system as TWRP will wipe it automatically before it installs any custom rom.

Thanks. I do want a out of the box experience but with CM12 nightlies instead of CM11S. It's been too long since I flashed anything to my device...
