Hi there,
I've recently moved from CM10-M2 to CM10-Nightly (10/19) and it seems to have mucked up interaction with Google (not getting pushed emails, problems with Google+)
I liked CM10-M2 well enough, and I was to revert back to that version...however, I've never reverted before, only ever moved forward.
So:
1) Is it complicated to revert to a previous version within the same tree (ie CM10 to older CM10)?
2) Is it complicated to revert to a previous generation (ie CM10 to CM9)? (Don't know if there's a point to doing this)
3) How can I upgrade/revert without losing ALL of my apps? Last time I did the upgrade I lost everything, and when Google Play started auto-downloading everything I wound up with a lot of apps I had previously uninstalled. When I upgraded, I did the full wipe cache/wipe dalvik. Do I need to do both of those on upgrades/reverts? (I had searched for the answer to this question, but it appears that maybe 'revert' is not the correct phrasing of this question).
Thanks a ton!
Save all your settings and apps with titanium backup and just flash the older version over it.

Hi, I've got a recently rooted HTC desire, and since rooting it I have been playing around with a couple of roms; I have tried both cyanogenmod and a desire hd rom. However with both I have had the same problem - having to start fresh completely, without any of my data. And then having to restore a backup.
So my question is firstly, am I doing something wrong? I have tried restoring my data before but all I ever get is a bootloop when I restart so I have to wipe it again.
And then, if you do have to start afresh, is it really worth it? And why.
Thanks for reading

I try to keep it simple.
You say you've tried restoring your data? With...Clockworkmod? Or what? If you restore only /data-partition with Clockworkmod (I'm not sure if it's even possible, never have tried it) you are bound to have problems.
Same goes with Titanium Backup. When you're switching ROM from say, a Sense rom to Cyanogenmod - don't ever restore all settings. The ROM's are too different and their settings aren't compatible with each other! I myself only restore WiFi Access point list (and installed apps) when switching ROMs.
So if I've understood you correctly, you're not doing anything wrong (unless you're restoring a nandroid after flashing...)
A correct procedure for switching roms (not for updating the same ROM unless stated explicitly!) is:
-Titanium Backup/Mybackup/whatever your apps (and as little settings as possible, it's mostly trial and error)
-Nandroid backup (so you can revert when there are problems)
-Wipe data / factory reset (wipes everything but FAT32-partition of SD-card)
-Flash the new rom
-Restore your apps with TB/something else and manually input your settings (accounts, etc shouldn't be backed up either...)
Something you could consider if you want to jump ROMs all the time, is to set up your installation the way you like it, then do a nandroid backup, install a new rom, then set it up again and backup it, then if you want to switch these 2 roms you can just restore the one you want...Of course replacing the nandroid backup if you've done a lot of changes
Now for your last question: Starting fresh is worth it. Otherwise you will most probably run to force closes and other problems that force you to do a factory reset anyway.
Thanks for the reply! Very helpful... so if I go into titanium backup and backup all apps, will that backup contacts and text messages etc. also? Or will I have to lose them?

Umm, I can't say about contacts, because I always sync them from my work Exchange & Gmail, and for text messages I recommend a free app called SMS Backup+ https://market.android.com/details?id=com.zegoggles.smssync&feature=search_result
The software backs up your SMS to your Gmail as messages, to a label called SMS , and they can be restored with a click to your new rom.
Also People app (in Sense) and Dialer (in AOSP roms) can export contacts to SD so you can easily import them back.
Alright so I had Google backup my applications, and I was running CM7. Then I tried flashing to SalvageMod (I did factory reset and everything) and since Google backed up my apps it put back all kinds of stuff from CM7, which makes everything a little wonky because it turned into a mix of the two ROMs. How do I access what Google backed up for me so I can alter what does and doesn't get backed up when I flash new ROMs? I tried Google.com but I couldn't seem to find anything pertaining to Android phones, but maybe I missed it. Many thanks in advance! I would really like to try out SalvageMod without CM7 interfering haha.
That is one of the reasons why I don't have my apps, data and settings automatically backed up to Google's servers. However, to attempt to answer your question, one step is to disable the "automatic restore" feature located in Menu-Settings-Privacy Settings. No, I have not tried it but it seems like a good starting point.

I'm pretty sure that this hasn't been covered specifically so I'm posting a new thread.
I backed up all my apps and data on a stock rooted Sprint 4.24.651.1, 2.3.3 ROM via TBU Pro. I also performed a backup of my current ROM with ROM Manager. I then installed Team Nocturnal _Shooter_RLS_2.3.(after, of course, all the recommended wipes and resets) When I went to restore my apps and data I wondered if some of the previous app versions (where both ROMs have same apps/diff versions) would hose things up. It did, I think. Maybe all that I needed to do was clear some app caches and reboot. Not sure, I couldn't get any of the HTC widgets to load but I did see in another thread that cache clearing may fix that. But other stuff was goofy after the restore too. It became buggy and horribly slow, so I think that there's more to it than just the HTC stuff. I wonder if something I restored and maybe shouldn't have hosed it up. What I'm wondering is if someone would be so kind as to scan down my app lists and tell me which apps and/or data that are obvious that I shouldn't restore? For example, this new ROM has a different dialer, it makes sense to me that I wouldn't restore that. Same with anything to do with Sense, since this particular ROM I believe has a newer version, but not sure. I am thinking that any time I install a different ROM this will be a consideration but maybe I have the wrong idea about the whole thing. I have attached 30 images captured (incl the Software info screen) of my app list in TBU.
Lastly, I'll add that since making the move to Android from WinMo about a year ago I am very glad I did it. I could not have possibly been able to learn and do the things (rooting, S-off, flashing ROMS) that I have done without XDA! You folks are brainiacs and I greatly admire what you all do. (blatant a**-kissing)Thank you, thank you!
You have to be very careful about what you restore using Titanium when you are moving from one ROM to another. I found this from personal experience (moving from Stock to Synergy RLS1 and then to MikG). There is some good info in the Titanium Backup Wiki.
The part that you need to be careful about is restoring system data that is incompatible with the newer system apps in your new ROM. Your best bet is to only restore the User Apps and their data. You can do this in Titanium by selecting Menu > Batch > Restore missing apps with data.
There is some system data that you can restore without getting into trouble (probably bookmarks, SMS Messages, Sprint Voicemail) but you are going to have to experiment. I restored my missing apps using the batch option and then went to the Backup/Restore screen to look at the System Apps and Data one by one to see if there was anything that I could restore. Sometimes I would restore some data that would cause a problem and I would have to Wipe that data (also in Titanium Backup/Restore screen) and move along. I know at least once I was forced to start fresh and Wipe and reflash the ROM.

Yeah, I had a feeling that there would be conflicts like that before I even restored. I never thought to read the TBU wiki...thanks for that tip! It looks like I have a lot more homework to do before I flash again. I really have to decide if the time investment is really worth the return. There are so many cool ROMs out there but what a lot of B.S. sorting out what works and what doesn't. It is excruciating to have to read through 50+ posts following a ROM release to find out what you're in for. What would be super-cool is if someone was able to construct a spreadsheet of the most popular ROMs in a column with all of the popular features (4G, Wifi Tether, Mirroring, etc), kernel compatibility, Sense or no Sense, etc in a row at the top, with check marks indicating whether or not the feature works or is baked in. I'd pay to see that. Especially if it were linked to the downloads to the ROMs and kernels.
Thank you very much for the reply!
Hey guys. I just wiped and upgraded from CM10 8/14 build to the 8/31 build. I always hate the arduous process of reinstalling apps (for some reason, the automatic restore of all apps from the Play Store has only happened once, I can never get it to happen consistently)
Anywho, I wiped, flashed the new build and gapps, and then rebooted and signed in. It decided not to auto-restore, so I decided to try and boot into Clockwork and do an Advanced Restore of only /data. Rebooted and I have all my settings and apps back perfectly fine. Is there a downside to doing this? It seems to have worked without an issue but I don't think I've seen people saying they do this regularly.
Also, does anyone know how to get the built in auto restore to work reliably? I have all the settings checked.
Thanks in advance.
I have done it numerous times that way, but as you go along, you will find that is not that reliable, use titatium or mybackup. Those always have better results. Either way is fine.

Titanium Backup is your friend! Its way more easier and you can transfer that folder from iPhone to phone. It makes life easier for us flashaholics.
I have a GSM Nexus 4.1.1 rooted using my Mac and it's running the XenonHD rom. I rooted a while ago and do not really remember the nuances of it.
I would like to flash a new rom that includes the enhancements of 4.2 but obviously want to keep all my texts, music, programs, settings, etc. I have read around but need some definitive answers on steps to take to flash a new rom but keep my phone entirely intact. I also remember having problems with the google apps when I first rooted and flashed, and would love to avoid that.
Any advice would be appreciated, and my apologies if this appears to be redundant. I am just not very good with technology and would prefer to have all the facts pertinent to my situation beforehand. Thanks!
First of all - make a nandroid backup through your recovery menu. That way, if things go bad, you can flash your backup.
To backup messages, application data, programs etc, I'd recommend using Titanium Backup Pro. Its a few bucks but if you flash often, its money well spent for sure.
Remember though, that when you flash a new ROM, restoring all your apps and settings from a previous ROM can cause problems. I would recommend backing up messages and non-system application data only. You can restore apps through the play store and then use titanium backup to restore the data for the app.
Depending on the ROM you install - you may have to install the gapps separately. See the ROM thread for details on that.
Lastly, if going to a 4.2 ROM, make sure you have updated your recovery as there can be some SD card issues otherwise.
