While I know that it would not be a good idea at all to flash my G1's system or boot images to my Nexus One, I'm wondering if it's possible to flash my G1's userdata image to my N1, which comes in tomorrow.
Thanks for the help
If you are talking about things like your contacts and calendar, that will sync automatically.
I would recommend against flashing it, if you don't have the same apps installed and since you (probably) won't be using the same OS build, there could be differences in the partition that could cause problems.
Nah, I meant things like my wireless networks, texts, etc. I can deal with starting over, was just curious if anyone had done it before.

seems like whenever i run an update.zip (superhero recent build is an instance) i get the same issues with each rom, i'm thinking when i do alt+w its not fully wiping the g1 and that theres another way for me to do it. mainly thinking this because some people are having paid apps issues where they have to run a command to fix permissions, etc. and i dont have to do that at all with any build so far...
thanks in advance and to the devs, keep up the good work, you guys seriously kick @$$.
a wipe does exactly that... wipe.
what about you spl and radio?
as far as i know i have the newest radio and spl, otherwise it just wouldnt boot up correct? for instance the main issue i have with the hero rom is that facebook photo sync causes crash in acore
After reading a few threads regarding issues when it comes to flashing, I would like to do Public Service Announcement about flashing ROMs. I want to compile tips and advice to people who are noobs like myself. Feel free to add/modify/correct these.
1. Back up personal photos, videos, music, whatever you consider valuable, onto your computer. Often. I remember reading someone lost all his son's newborn pictures because a ROM fully wiped his internal SD card. Don't let this happen to you.
2. Use Titanium Backup app. If don't know what this app is by now, you should. This will back up all your downloaded apps from the Market. DO NOT, I REPEAT, DO NOT BACK UP SYSTEM DATA. Get the paid version! Only back up your own apps. If you flash a new ROM, restoring system data from another ROM would/could screw up your freshly install ROM.
3. If you're flashing a new ROM, I highly recommend this method for a fresh and clean install:

4. Flash at 100% battery. Never risk bricking when your phone has low battery. The phone could die when the ROM is installing. It's basically full of DO NOT WANT if you're flashing on a unfull battery.
4A. If you didn't flash at full battery, use the app called Battery Calibration. The app resets the battery info, so ideally use this app when at 100% battery. Or follow the instructions in the app.
5. Make a Nandroid backup via CWM. Preferable before you flash a new ROM, kernal, framework, ect. I'm OCD, so I personally make a Nandroid backup about once a week. You never know if your phone is gonna bootloop or boot properly. Backups WILL save your life.
Again, feel free to correct me if anything is wrong. Happy flashing!

I always wondered about backing up system settings and restoring on a new rom. Granted, it'd be perfect if you're wiping the current rom but flashing a new one and then restoring old settings would probably mess it up! Great post, bookmarked!
So only my second CWM flash coming up (work takes up way to much time to be playing with it as much as I'd like)
Currently on Alien #2, going to upgrade to 4 and the 1.77.30 radio.
Will going through all the fastboot wipes eliminate EVERYTHING? And then, when flashing Alien4, will it all be restored?
It is my understanding, perhaps wrongly, right now that Alien does not touch the webtop, so if I wipe the webtop partition, flashing alien will not restore it and I will need to restore is separate/manually for example?
Whenever I flash a custom blur-based rom (not cm7) - sorry if I am using the wrong
terminology, it still has some reminiscence of previous setting - mainly is the screen
setting. For example, a quick note widget with content I typed in and a whatsapp app
shortcut on the Home screen even though the app is not installed after a flesh flash .
I did do every steps listed by op. However, I did skipped the fastboot steps after wiping the big
3 in recovery during my first few times of flashing a new rom.
Is it normal that some of the previous settings are retained?
Photobucket is great for backing up pics in the cloud, every time I take a picture its instantly automatically uploaded to my Photobucket for storage. You can pick a picture quality to match your battery/data usage. I know this is slighty off topic but hopefully noone looses any more baby pictures..
ok guys, i have had my ****ty 3rd gen ipod touch for a while now, and this christmas i know I'm getting a nexus 7. now i consider myself fairly good with technology. but the only realm i havnt explored is android and that starts with the nexus 7. I am planing on rooting, but keeping the stock rom. I know i can't do ota updates with root. So the only way if i wanted to update my nexus 7, would be by flashing the next stock rom via twrp. the question is will it keep ALL MY DATA (apps, media, and settings)???? if not how can i keep it?
thank you and thanks in advanced.
if the update changes the version of Android, like from 4.0 to 4.1, then a wipe is recommended. if its only a small update, like minor ROM update, and the android version stays the same (eg. cyanogenmod nightlies) then there is no need to wipe. You get to CHOOSE (and you will hear this word a lot in the world of android) to wipe your data or not with a custom recovery. just dont blame it when your apps keeps crashing after an major update.
how does keeping your data work with ota updates then, wouldn't it be just as dangerous? also i would format? then restore my data with titanium backup?(right?)
If you just unlock/root, but do not install a custom recovery, you should have no issues receiving ota's. It's the addition of a custom recovery that prevents the ota from installing. Though you may lose root, so an app like ota root save is a good idea.

Can someone give a straight answer?
Do you lose data if you flash ROM?
For example flash the exact same ROM twice? Would data, like SMS get deleted?

Straight answer is... no...
If you're flashing 'like-for-like'... that is to say UPGRADING a given ROM, then generally, you just 'dirty-flash' over the top.
If your're changing ROM completely, then a full SYSTEM WIPE is probably recommended.
Rgrds,
Ged.
Usually if you already did the unlock and recovery process (usually a one time thing in the beginning), then you mainly just have to understand the 3 main partitions you're dealing with on rom flashing from recovery.
/system = this is where the system/OS files live, and where for the most part the roms install to
/data = this is where the usual user data lives, since the /system rarely changes, stuff like settings, downloaded applications, etc is stored here. Rom installs rarely ever wipe this, and normally it does not need to be wiped if you're upgrading from one rom to the next (such as going from SlimBean 6.0 to 6.2, same type of rom just an upgrade). If of course they are different roms a /data and /system (and cache/dalvik-cache) wipe is recommended before flashing the rom.
/data/media (if I got that right) = sort of the "media" area of the device where you will store most of your stuff like downloads, music, pictures, etc. In recovery, wiping /data will usually not touch this, it's just like the /sdcard partition on older phones.
When trying out a new rom, it is always best to backup via recovery, the backups are stored in that media area I spoke of, and it's also advised to copy them onto a computer when you get a chance. The Nexus 7 and TWRP Recovery supports USB-OTG so you could plug up a thumbdrive and save the backup there directly. If you run into problems, you can always go into recovery, wipe everything and restore from a backup.

By the way forgot to mention, even if you're just flashing an upgrade, it's still idea to wipe the cache/dalvik-cache (it won't affect your data, but new binaries should be reloaded by erasing the cache so they can be re-built).
Thanks guys. My phone was stuck in boot loop and I had to flash the stock ROM again and again and again until I got it working.
I lost several messages, that is what I expected.
However, before I torched and burned the phone with ROMs, I backed up the device (or whatever I was backing up, I dont know) with CWM backup.
Is there a way I can get those SMS messages out of this backup?

If you have the PRO (paid-for) version of Titanium, there is a way you can extract stuff from Nandroid backups... but I don't have a 'Tilapia' Nexus 7 to test. (with regard to your SMS problem).
Just running it (Extract from Nandroid backup in Titanium PRO) on my 'Grouper' Nexus 7, and I can see all my apps (and associated data) in my last Nandroid available for individual extraction and restore.
Rgrds,
Ged.
It was a stock ROM, nothing out of the ordinary. I mean, there was a different kernel, I've put root kernel. So, if there is option to get it from stock system, that would be nice.

I have a 32GB N7 that I share with my girlfriend. I quickly learned that if I flash a new ROM, that whole other user's info is gone.
After trying to restore apps and info using both Titanium and ROM Toolbox, I couldn't get it to function like it was before.
I tried to restore to a backup I made prior to doing this and it won't get past the boot screen. I can safely assume that whole other user account is gone. The question is, how can I bring that from one ROM to another? Or how can I restore back to a previous ROM that had it setup?

I could be wrong about this as I am very new to serious mucking around in Android but...
Were ROMs you were using previously based on 4.1.x or older? I know that it is only a very recent version of Android that has proper multi-user support (4.2.2 has it for instance.. I'm not sure about 4.2.1 etc..) and thus now places a "0" folder in which the main user's data is saved, and then there will be "10', "11" etc.. for subsequent users. I'm not sure if your data is gone or not depending on your exact situation, but there are issues that can come from trying to get recovery/data from "pre-MultiUser" and "post-MultiUser" ROMs. Sometimes you may be able to manually move or stipulate where you want to recover from etc... others, it may be gone. There was a post about this from TeamWin and their TeamWinRecoveryProject that explains a bit more of it... http://teamw.in/DataMedia
Not sure if this is helpful, but it is worthwhile to look into regarding multi-user Android.
I am having same problem as OP. I share the N7 with my wife and when I flashed ROM I wasnt able to restore any of her data through Titanium, but it would let me restore everything that was on my main user account. Had to switch back to stock rom nandroid, and her data was still gone and mine was all intact. Now she won't let me put a custom rom on If anyone has any suggestions/fixes I'd really appreciate it. Thanks!

Probably had to have titanium on both accounts, then created the account after ROM flash and titanium restore on both accounts sperately

If anybody had seen my previous issue I apologize for wasting your time, I was able to resolve the issue by wiping every last bit of data from the system, which resulted in the tablet having no OS and I was able to re-install Pacman without further issue.
But now my question is this, with seemingly everything back to normal, so far as installing a new rom goes, how can I get my necessary google apps back onto my tablet?
Also how can I restore the apps I previously installed? I see that everything is still on the storage but I can't access any of the apps.

Did you reflash the gapps? Thats the only way to get the necessary gapps that I know of. As for the restoring your old apps if you didn't use an app backup like mybackup pro or titanium backup then I don't know how you'll get them back.

So far as the apps were concerned I suspected as such, I just figured that the data would be readily available but a lesson was learned.
And yes I did try to reflash gapps but I still got the error prior to reflashing the rom after wiping the system data.
But I got frustrated with it and backed up my system data back to stock; I was thinking maybe I used the wrong gapps file for my rom but the app I used found the file that was compatible with it and so I thought it was safe to use, but after trying to reflash gapps 3 times it didn't work at all.

Thank you very much for your help, I'll have to try this next time I use a rom, won't be any time soon after my first bitter taste of having used one but I still appreciate the help.:good:
