[Q]How does the WiFi remeber old networks? - Xperia Arc Q&A, Help & Troubleshooting

Hey guys, I have my arc and I used it to access multiple WiFi networks, after that I falshed new Rom, downgraded and did many things, in the end I open my WiFi settings and I have all the names of those old networks there, I wonder how come they weren't removed after flashing?
It doesn't bother me, but I just want to understand

Yes I did wipe the data, the cache and even formatted the system, when I saw the old WiFis I was really surprised
I totally agree with the sdcard explanation even though I don't know how or why the WiFi modules would use it??
Sent from my LT15i using XDA

Did you sing up to sync your data with Google or Sony account? I think this might be the thing. It happened same to me, and I also wiped all data (/chace, /data, /dalvik,...) changed my rom to ICS, and on startup all my old WiFI networks were already there. And I think, I have also formated my SD card, so it could not be SD card.

I'm sure google back up remembers them so when you log in your settings are there. the back up your data setting I think

You are right, your setting is backup with google account, you might be using same google account in old and new ROM, so after signing with google account in new ROM it will sync all setting and contact no etc....
I think this the reason you are getting old wifi listed over there. My own experiance

Right guys, google backs up the information, thanks everyone

Datasd2 help!! Phone semi bricked!

Hello forum, I just joined today mainly for the issue I'm going through right now. I have a Motorola Triumph from Virgin Mobile that runs Froyo 2.2. Lately, I've been getting low storage space notifications and it was driving me nuts. So I went on Playstore and downloaded Data2sd and to be honest, I really didn't know what I was doing. I launched the app, granted the superuser permission, and I created a 300mb partition onto my sd card. Then I selected data on the menu option and started selecting all the movable directories to move into my sd card. Everything seemed fine since I was keep getting the "moving succeeded" message, only until I rebooted my phone. That's where my problem is. I noticed my wallpaper was gone and the android launcher was keep crashing, not letting me do ANYTHING at all. I'm so frustrated and I really dont know what went wrong. Please help! I don't wanna reset my phone because I dont want to lose all of my important contacts! I apologize in advance if this has a simple solution, I'm still kinda a noob at modding android phones. Thanks.

If the contacts are the only problem, i believe you can backup them via ADB. Also, try uninstalling Data2sd. If you want a guide ask me

Nevermind, i got it fixed! all i did was somehow manage to open my browser and download home++ beta launcher. Through that, i was able to back up my contacts and whatever I needed, and did a factory reset. That fixed the problem! now I've found a better app than data2sd and that is links2sd. That works like a charm thanks for taking your time to help

Google music and flashing new roms.

We have been blessed with so many devs for the incredible 2, that it can be easy to flash a new Rom often. My question is this:
How can I keep my google music that I keep on the device to each Rom? That way I don't have to download it each time I flash a new Rom or update one with a full wipe?

Music on your sd card under mnt>sdcard>music, shouldn't be affected when you flash a rom.
If you recently flashed a rom and it is no longer showing up, you may have a media bug that seems to be going around. I would recommend reading through the rom thread to see possible solutions.

fyi...if you do have the same problem many of us had, flashing a rom may not correct it, but deleting a file on your sd card root called .nomedia may fix it even without a flash...

You really need to be more specific with what you are trying to accomplish. If you are wanting google play music to just remember what music you have in your account, titanium backup works very well for me, I believe it also keeps the music that got cached by play music to play offline.
If it is music you proactively transferred to your sd card and your phone isn't seeing it, you need to reconsider my advice of searching through the rom thread for a fix. I don't believe you have mentioned which roms you have tried, nor did you acknowledge if you had looked for the .nomedia file.
Your correct,sorry about that.
I am trying to keep the google music cache. (i think). I have done something to tb in the settings or something to where it won't restore it.
Tb just has so many things you can do with it that I think I have messed some stuff on it. Maybe with having different profiles.
Maybe I should just clear all my data with it and start over. And then backup my phone three easy I have it now?
And no I have not found the nomore file. Would that be under the music or somewhere else in android?

The .nomedia file would be in the root of your sd, but that won't apply if you want to just preserve your cache info. Here is what I would recommend, although I haven't used profiles in titanium, so take it fwiw...
In each profile of titanium, tap on google play music and tap delete. Then go into manage apps, tap on google play music, clear data.
Then go into google play music, make sure it signs your account in, let it run the process of finding all of your cloud music.
When that is done, go back into each profile of titanium, backup google play music, flash new roms, profit...
I don't know if it will work, but I think it is your best shot.
Okay I still am missing something. I cleared all data in google music.
I uninstalled the app.
I cleared all data on TB.
I deleted all the files on the sd card for TB.
I reinstalled both apps and set it up.(meaning getting all my music to on device.)
I backed up everything.
Flashed new rom (ukb)
Restored my apps and data.
=fail it just installed the app not the cache, to tell google that it is there. Unless TB does not save the music? So now I am unsure what to do?
I guess I will have to get all my music in a folder and place it on the sd card somewhere (which in turn I am nit sure where; in order for gmusic to see it.
Any other thoughts or suggestions would be much appreciated!
Now that we have the leak for the dinc2 I am sure there will be some fun stuff to flash soon!

[Q] I've had my T-Mobile Samsung Galaxy S II since October 30 of last year

Almost a year now, haha
I haven't rooted and/or put a custom rom such as cyanogen mod or anything, although I have been curious.
If I do go ahead and do it, how would I keep all my data and stuff, like pictures, contacts, messages, game data, etc.?
And how easy would it be to revert back to the stock T-Mobile ICS rom and stuff including the unroot, e.g. factory (how I got it)
This is the general statement and I might have more questions about this later

Stuff like pictures are stored on your SD card and wont get wiped by flashing a ROM. Stuff like programs and settings can be saved with Titanium Backup.
Don't I have to root to use titanium backup? In turn, doesn't that wipe everything?

No, rooting only gives you root access. All it does is give you permissions that you or apps will usually don't have. Like stated earlier deleting data or system will not delete your files and pics. To do that, you will have to format your SD or internal card. Quite different from rooting.

Back your pics up to a computer. Game data, messages, etc., can be restored via titanium backup or other similar apps. Your contacts should be backed up on your Google account. You can log into the account on a PC to confirm this.
I'm not sure on the unroot process or the level of difficulty since I've never done it.
Rooting does not wipe your data as previously mentioned.

I used it religiously for over a year but have since stopped. Its nice and might do you some good, but rooting and flashing a custom ROM will alleviate most battery problems.
I read that Tasker is a good app for managing your phone, battery, and a lot of neat things.
Is it worth the $6.49?
Also, do I need to unlock the bootloader?
You would lose all of your app data and that kind of stuff but don't worry about your pictures. Also, just backup your contacts to your SIM than restore it after you flash what you want. Also, it is super easy to unroot. Check in the dev section. You will find stuff about returning to stock.

Airdroid deleted my "sdcard" ?

So I already had songs, pictures, etc on my Nexus 4, now decided to install Airdroid.
The app didn't work as I wanted it but anyway, I opened my Gallery on the Nexus 4 to find out that all my images/photos are gone. The next thing I do is connecting Nexus 4 to my laptop. All folders/files are gone ?! Or maybe they only got moved?
wtf ?!
That's weird. I have air droid and just used it last night. Works great for me.. I don't think stuff can move by themselves after disconnecting. Maybe try a media scanner app. Rescans SD and organizes stuff.. I have this one https://play.google.com/store/apps/details?id=com.clypher.mediascanner
Sent from my Nexus 4
nope re-scanning didn't work... I just wonder what else airdroid could delete... pretty much my whole "internal space" is gone (the space that shows when u connect the nexus to your windows 7)
Flash a Google stock image to your phone.
why would flashing a new OS bring back my old data ?
Sorry I don't know then.. That's a new one for me. Never had that happen..

It may make your storage usable again. But if you try that your old data will be gone.
Well the storage is usable...its just that all my old data is gone. So there is no need for doing that? Atleast aslong as airdroid didn't delete anything else :S

[Q] best way to back up personel

before i take the red pill and flash the wicked rom, what is the best method to save personal data phone #,contacts, calendar appointments, email passwords, alarms, etc.?
the wicked rom says not to backup system apps, does that include app data?
thanks
Titanium Backup. You can restore app settings, say alarm clock settings, Temple Run accomplishments, etc.
I just export my contacts to my sd card and import back on a new rom. You can also link your contacts to a Google account.

Search your internal storage, it shouldn't of been deleted. Go through a file manager and if you can find it, go to titanium >preferences >and restore location.

yeah, you have to change backup location in titanium settings. In the S3, it uses your internal memory as an internal sdcard. That is where it saves all your personal junk by default. When you wipe though, it is possible to wipe without wiping that data, a factory reset should be enough. If you change in settings though, you would need to configure it to use your external sd card.
