"Cleanest" way to upgrade? - Nexus 7 Q&A, Help & Troubleshooting

What is the cleanest way to upgrade for Smoothest Rom? I've read its just cleaning cache and dalvic but for others I also read factory resetting makes it so its completely cleaned before upgrading?
So which way is the "cleanest" way to upgrade?
I just wiped both caches and then upgraded to smoothest 5.1. Is this gonna cause problems later?

Please help

Whenever I flash a new rom I always:
Wipe both caches and then Factory Reset
Then I flash the new ROM, it's always a safer bet too.

I do the same and it always works.

The absolute cleanest way to upgrade will always be to format system and data as well as cache before flashing. When you're just updating top a new version of the same ROM, though, that usually isn't necessary.

Yes, but next time please ask questions like this in the thread for the rom that you want to switch to as this question did not warrant the starting of a new thread! We already have way to many threads like this cluttering up the forums!

ok sorry. So all I do is boot into recover and wipe cache then install?

For me I leave it on charge and at 100% I boot into recovery wipe cache, devlik cache, then factory reset but you may get buy without having to do factory reset since although different it still is cm 7 but if you don't factory reset and it won't boot do a factory reset then it should boot

It does support them but not as a blur rom does cm7 puts internal under mnt/emmc and I think miui best I remember is the opposite. But mods can be done to switch them.

Can I do a restore when on a custom Rom?

Ok I can't find anything to answer this question. Therefore I am asking, because I just don't believe this has been asked be4. I am running Revolution HD 6.3.1. My phone(HTC INSPIRE 4G) sometimes just slows down to a halt. It started about a week ago. I have uninstalled a good many apps, and cleared plenty of space. Prior to rooting, and flashing I had this problem and restoring to factory setting fixed this. Ok now that I've explained that, the Rom(as stated above) I'm on has the option to do this. I want to know if I do this if it will "restore back to just flashed condition" although it says factory condition, but Is a flashed ROM. Will it just simply put, brick my device, or reinstall the Rom as if I had just flashed it. Thanks ahead of time.

Ir you factory reset the phone you will get stuck in the splash screen. If you want to go back to stock, the restore a backup from CWM or flash a stock Rom from CWM. Factory reset does not work in custom roms...

Thanks for that response. I'm not interested in stock at all. I just wanted to know if it would work. Root and flashed Roms are always smoother, even if some of them have bumps. Truthfully I'm waiting on a RC Rom from Existz, as I just want a stock android experience

In CWM wipe data and cache and it should be some sort of factory reset.

Update rom

My first ROM on my N7 is paranoid android of course. I have the build from September 9 and the latest is now available (goomanager informs me). After I down load this zip, all I have to do is flash this new file in order to be up to date?
Thanks

All you have to do is reboot into recovery, wipe cache, wipe dalvik cache, flash the ROM, flash gapps, then reboot. Always wipe caches and re-flash gapps when you flash an update to a ROM.

So if I'm understanding you correctly, after I wipe the caches... reinstall the rom and then put the latest version of gapps? (Just like you did to get the rom working in the first place?)
Thanks

Yes. I don't know if you did this before you installed paranoid android, but it's a good idea to do do a full wipe/factory reset when you switch ROMs.
Once you're on a particular ROM, you only need to wipe caches before you flash the update and gapps.
Sorry if that was confusing

My pleasure. Watch out though. Flashing ROMs can get very addictive.
Have fun, Doctor!

Getting fc's on on all roms

Just like its says. I even backed up stock ROM and now getting fc's on July plus
Sent from my Nexus 7 using xda premium
No need to start a second thread for this... I'll say it again, have you wiped data in between ROMs? Or what are you doing after installing the ROM if you've wiped it?

Make sure to wipe everything before installing a new ROM, then run fix permissions (advanced options in CWM recovery) from either your recovery or from ROM Manager. After reinstalling all your apps and settings, make sure to fix permissions again.
Wipe system before you install your ROM, in addition to wiping cache, dalvik, data. If you do it right it will work

Typically unnecessary, as it its generally wiped during the install process.

I like to be sure, and I haven't had any problems installing ROMs on my N7, and I've flashed pretty much every one there is, kernels too. There have been ROMs that liked to be flashed 3 times for no real reason, so I say its good practice to manually format partitions, caches etc yourself, even if it's supposed to be done on install. If I do it manually, I know that it has been done

You could probably use adb to side load a ROM and gapps, here's a example of how to http://forum.xda-developers.com/showthread.php?t=2317986

Isnt factory reset, just wiping cache and dalvik? If yea, then dirty install isnt the best, depends on rom that im moving from.

factory reset wipes /cache, and /data (without wiping /data/media <--thats where all your pictures and rom zips are stored)
factory reset is needed when moving between completely different ROMs (you can get away with dirty flashes between SOME roms, but its rare)
Oh yea yea, I didn't wipe the internal, something went wrong and the file was deleted, but gapps was there and all my data was there, anyways fixed and got the new nexus 7, enjoying it, much faster and better!
