Reverting from CM7 nightly to stable? - Nook Color Q&A, Help & Troubleshooting

Do I have to clear anything to go from say CM7 Nightly #94 back to the last stable release? I got bored & tired of waiting for a new stable & installed some nightlies & need to back up to fix what they broke.
Thanks,
kev

The big problem is that you came from a stable 2.3.3 to nightlies 2.3.4 and now back to 2.3.3 I read somewhere that going back can cause some FCs if I remember the fix was to go into setting / applications / manage applications / and then clean the cache and data in the app that is giving you the FC. good luck

You should format system before installing the stable. That should help with any problems. Just remember to flash gapps again.

sorry, but do you mean wipe /system?
format before install seems to imply a fresh install, basically doing everything over again?
thanks.

if i were you, i would try the cm6 fix. the instructions for this fix or workaround or whatever you want to call it have been posted numerous times in this thread.
thanks for the reply. i did the cm6 install and then loaded nightly 23. GPS was working. worked great but had to download and install all these apps that weren't backed up properly fom titanium and just had to redo the whole phone, contacts, everything. pain in the butt. then i learned that once on a nightly, all you do is wipe cache, diviak and bam....load new nightly. so i went from 23 now onto the new CM7 RC1 without redoing any apps and contacts and what not. awesome. so zervic, your telling me if i do the cm6 fix, i have to do factory reset and do the whole thing over again as in restoring everything? or can i just wipe cache and divack, and install cm6?

incorrect. you do not have to factory reset. the reason for this is because, you take a nandroid backup of your cm7 before you wipe your data, after the install of cm6 you'll be restoring that back up, settings, apps, etc included. I would search to find the exact steps for this "cm6 fix" though...but yea, do not worry about your apps and all that, they will be backed up. also. factory reset from clockwork, not from within the phone (i.e. in the ROM). if you do that, it wipes your SIM too..

[Q] CM-6.1.0-RC1 ----> CM-7.0.0-RC1 ~ Upgrade Steps

Hi all,
This is probably a pretty basic question for you, so please bear with me, and if it is basic, hopefully there is a straightforward answer .
Having settled on the awesome CM-6.1.0-RC1, I haven't looked to change ROM.
However, with CM-7.0.0-RC1 being released, its time to upgrade .
Can anyone please explain the steps needed to follow in order to go from CM-6.1.0-RC1 to CM-7.0.0-RC1 please?
I appreciate there is a lot of info in ali ba's dev thread [ [ROM] CyanogenMod experimental builds] however, there is approx 235 pages there, and the OP is a little lite.
Would it be possible to have guide here, as I presume many people will be wanting to follow the same upgrade path.
I am wondering how we can 'save' apps, [i.e. Angry Birds status, web browser installation, general settings/config,] during the upgrade... because I am guessing a full wipe is required and therefore a Nandroid backup won't really help...or will it?
Anyone that can help?
I'm also running CM6.1 rooted and I've tried upgrading by downloading Rom manager and then booting into recovery, doing a factory reset/wipe data/wipe cache/wipe dalvik cache - and then flashing the CM7 RC1 zip but I get a boot loop every time.
I've tried removing the SD card and Sim card but same error appears.
Actually it's weird because I've been getting a boot loop with every firmware I've tried to flash except for CM6.1.
Luckily I did a Nandroid backup...

First question should be:
Do we need to wipe when upgrading from CM6.1?
If we need wipe, I suggest you to:
- do a nandroid backup
- backup all apps with titanium backup
- wipe + flash 7.0 RC1
- download and install gapps
- restore apps with titanium backup
If no wipe required:
- do a nandroid backup
- flash 7.0 RC1
Question: does UOT kitchen (for circle mod battery) works with 7.0?

Issues?
Experience issues? Please provide the following info:
If the device was hard reboot, please provide the file "/proc/last_kmsg".
If the device was soft reboot or is "bootlooping", please run a logcat and provide the full ourput.
Please use Pastebin when possible

Upgrading from earlier version of CyanogenMod 7?
* Perform a NANDroid backup of your current ROM.
* Flash CyanogenMod (your Google Apps will be backed up & restored automatically)

So no, you do not need to wipe before upgrading,
The backup is just for security reasons. You never know what could go wrong, so it's good to have a backup in place.
Just flash the new CM 7 and you should be good to go.
^ Mastacheata - thats if you're upgrading from earlier version of CyanogenMod 7
That question we are asking here is what if you're upgrading from CM6.1.
Oh I'm sorry, I misread that the whole time.
Gonna try it now and report back in a few minutes.
I've not gone 6.1 -> 7rc directly, but I did go from 6.1 to a 7 nightly build a couple weeks ago without wiping and I don't seem to have any problems (except GPS not working).
I'm thinking I may just do a full on Titanium backup, full wipe, then go for CM7.0RC1.

GPS not working in CM7.0 RC1 ??
Do we even have a list of things not working in CM7.0RC1? Again, the OP in the dev thread is a little lite with respect to 'known issue' and similar.
My test was unsuccessful.
I was neither able to install directly over 6.1 nor with prior wipe.
My phone would always end up in a boot loop.
Logcat did tell some Exceptions for unknown permissions.
Detailed explanation will follow in the developer thread.
i accidentally flashed cm7 build 0 over cm6.1 stable before. was able to boot but my phone was laggy & some features were broken, as far as i can remember. so i guess the best path is:
TI backup
complete wipe
flash cm7
TI restore
cliche by now, i know. but it never fails...
As we start the RC phase of CM7, many of you are now taking the leap from CM6 stable to the new RC's.
Some of you may be able to get away with doing this without a wipe; however, most of you will not be that lucky.
Differences in the rom, files system, and even Google Addons will likely throw most of you into boot loops.
Therefore, here is my recommended upgrade path:
1) Nandroid backup your current rom
2) Update your recovery to the latest available (CWR is my choice)
3) Format system via recovery
4) Wipe/Factory reset
5) Flash CM7 then Google addon 1/20
If any of you have data that you must absolutely save, then and only then should you use Titanium backup (or other backup apps) to restore your data. Please be sure not to restore any data to /system using these apps, as this will mostly likely corrupt your ROM and/or Market.

Perfect, I shoud've found that myself .
Now its just a question as to whether to go to CM7.0RC2 - lots of people still reporting bugs...

For those who update 'nightly'

How do you do flash the ROM every day and not loose all your settings, apps, etc. and have to re-download and reset everything again?
Or do you not loose all this when you download new nightly builds of CM7?
I never understood this either. Either you can flash over the previous 'nightly' and that preserves the settings and apps or they do a titanium backup of the apps and settings and flash that back on after doing a wipe. Don't know for sure tho.
The nightlys are too bleeding edge for me tho, tend to stick with a stable rom until cyanogen releases a fully compiled version.
I flash nightlies nightly. All you do is flash over the old one and everythings still there.
So you don't do a wipe in Rom Manager before you flash?

Never. I haven't wiped once in about 30+ updates. Phone runs great.

1) download update and put on SD card
2) enter recovery
3) Wipe cache/dalvik cache (notice. Don't wipe data. this is how you keep your apps/preferences/etc.)
4) Apply nightly update .zip
4a) If you're running a launcher mod (other than ADW) you can go to reboot recovery then flash the launcher mod as well to save your homescreens.
5) Reboot.
I don't even do that. Just flash straight from ROM Manager. I also don't backup before every update either. Think my current backup is nightly 15.

But, the very first time you installed a ROM you had to wipe everything?
It's just the updates where you don't need to wipe, right?
Yeah, you only need to wipe when going to a new version of android, eg 2.2 to 2.3

or... between CM and Gv or MIUI or Sense. Just good practice to wipe when making huge ROM changes.

If goggle "what is dalvik cache", you'll probably get back to an xda thread, except that the first reply tells you to go google it, lol. Don't worry, though, cyanogen gives a pretty good summary of what it is in that thread a few posts down.

[Q] Updating Wildfire's Cyanogenmod

Hello, im going to updgrade my wildfire's CM7 RC1 to nightly 203 (or newer if i dont get it done today), so do i need to wipe anything from recovery before flashing? I know u dont have to when upgrading a nightly to newer nightly, but how about this case?
And do my personal settings, data and apps stay after i flash nightly?
Yes, Just flash over the RC. Everything will remain intact. (But, Just take a Nandroid Backup before doing this, in case the new Nightly turns out to be unstable)

Thx for fast answer
What 3xeno said. I flashed a nightly over my stable release version with only clearing dalvik and cache (not even sure if this is nessecary) and all my settings remained. However I have heard from other people that sometimes this can cause instability issues, so if your new ROM is very unstable, it might be a good idea to do a full wipe and start over from scratch (factory reset)

CM7 Nightly to CM7.2-RC1 MiRaGe - KANG

This is my first post and sort of new to this. I have two simple questions.
1) I am running latest CM7 nightly in mSD for Nook Color. Can I simply place CM7.2-RC1 MiRaGe - KANG build onto mSD to run it? Will the system recognize the file and overwrite my nightly?
2) Can I also downgrade from latest CM7 nightly to a stable release by placing stable release into my mSD?
thanks ahead of time for help.

Yes to both.
thanks for the quick reply.
I have one more question if anyone can answer. Sorry for being noob.
I just start using android/Nook from iOS. I can do just about anything inside iOS.
Here is my question when I update to stable/mirage build does my data and settings retain? This just update (overwrite) nightly and install. Correct?

Unless you factory reset, all settings and installed apps will still be there after flashing a new ROM.

Something I've been wondering,,,after performing an update build while running off of mSD should we be wiping cache and dalvik cache? And if so, how?
Or is that only a emmc thing?
I would think that even running on mSD both cache would still be needed by the ROM, and therefore could be wiped.
Thanks.
If you're running off verygreen's SASD... it wipes cache when you perform an update.
Arggh!! <smacks hand to forehead>
I've sat and watched the output numerous times during a install/update and noted the "flushing cache" message. duh.
thanks for the reply.

It does not wipe cache. That message means something else. It is just cleaning up after itself.

The only way to wipe cache with a verygreen SD install is to use third party programs like Titanium Backup. It is not really necessary as the system will rebuild the dalvik cache if it needs it. (Actually you can use a specially modified CWM recovery to do it, but not many people have that installed.)
Thanks clearing that up leapinlar.
I gave it a shot using TIB, and it reported 2 files as not needed for a total of 5.1mb removed.
I do remember viewing a thread somewhere in reference to that modified CWM. After review, I felt that taking simple SD image backups would suffice rather than using modified CWM in this instance. Only other benefit to CWM I felt I was lacking is cache cleanup. So looks like I have that covered now.
Thanks again.
