Way to erase all data without restore?

I just got off the phone with apple and they tolf me to take the phone to verizon for exchange due to wifi issues. I don't really want to go through the whole restore process plus Verizon may not like it restored in order to check it out. If I use erase all content under the reset function, will that securely remove all data?

I recently sold my iPhone 4s and followed the erase all content route but didn't stick long enough to see it through, and I found some iPhone data recovery app can restore deleted data from iPhone without backup files, so, I think we have to permanently erase everything from iPhone device before selling it, some “Deleted operation” really doesn’t erase all the data and it still out there, you cannot it.

  • I live in Canada.  Each time I travel to the US, I lose all calendar entries.  I have to erase all data, then restore from an iCloud backup.  Tedious.  iPhone 4, iOS 7.1, sync set to all events.  Any suggestions?

    I live in Canada.  Each time I travel to the US, I lose all calendar entries.  I have to erase all data, then restore from an iCloud backup.  Tedious.  iPhone 4, iOS 7.1, sync set to all events.  I only use the default calendar.  Do I have an incorrect setting?

    I did find another point worth mentioning. 
    I use my iPhone 4 with a corporate Exchange email account.  I had deleted the account from my phone just before I did this backup/restore process...and I thought my battery drain was much, much better (if not outright fixed). 
    Later in the day, after seeing my battery life improve to near-new behavior, I re-added my Exchange mail account.  Considering I have 1 yahoo account and 3 gmail accounts, the Exchange account adds a 5th email account.
    What happened?  Battery drain back to "worst case".  Removing or re-adding the Exchange account is like toggling between decent and terrible drain conditions.
    Bottom line is that I re-added a couple dozen applications and battery life didn't change.  By far, the Exchange account drains the battery worse than any other app and setting.  This account must be polling very frequently and since people tend to send very large file attachments to that account, perhaps those effect the battery drain even though I have the account set to not download attachments.
    Anyone running Microsoft Exchange might be able to confirm what I see?  If so I can open an enterprise ticket with Microsoft and bug them on this issue.

  • Is there a way to clean up data without restore and backup?

    I noticed recently that too much data is being silently stored on my iPad possibly be apps and caches.
    Isn't iOS supposed to clean up data as it needs free storage?
    most recently, according to usage in settings > general, I had 1.8 GB of free space. I wanted to install an app that is 2GB in size. iOS told me there was not enough free space. I could not find what used so much data, and frankly this time the list of apps in settings > general > usage proved to be pointless. Adding the numbers together of how much space the apps were using up was nowhere near enough to leave me with only 1.8 GB of free space.
    I did a backup, then restored my iPad. After that, I restored the backup with all apps and data I had before. Now I have 7.2 GB free space. 5.4 GB of temporary and junk files, with no way of erasing them, is quite frustrating.
    Anyone knows a solution or shall I just restore my iPad pretty much every 2-3 weeks? (Yes, the last 5 or 6 restores I have performed were solely for freeing up storage space that mysteriously keep being filled up.)
    Additionally, how do I find out which apps use up so much space when settings > general > usage doesn't tell me anything? Only how much space the app itself needs and how much permanent (user generated) data is being stored. Such as pictures, save game files, and so on, but nothing about cache sizes temporary data.
    PS: if the above was asked and answered before, please accept my apologies and could you link me the topic it has been resolved in?

    Hi! And thanks for your reply!
    It sounds sensible. Since the last restore which was just over a day at the time of me writing this reply, there is over 1GB of data unaccounted for. Note that I have not installed new apps, nor DLCs within games. The two I have been using heavily are Netflix and Youtube, both of which should automatically erase temporary data. Or so they claim.
    However, there was a period when I had my iPad on charger overnight. When I woke up, just out of curiosity I checked the usage statistics and I found my free space was about 200 MB less than when I checked immediately before goong to bed. So the iPad was not used at all and somehow I lost 200MB.
    I did try a software for Windows called Phone Clean, but that didn't help. Before the restore, I ran a deep scan, and it only cleaned up about 500MB of data even though there was nearly 5GB unaccounted for. I performed the restore, and that was when I thought this is beyond me, and posted this topic.
    I have also noticed that when I watch a movie with the Videos app by streaming from iTunes instead of downloading, after watching it, the storage will not get freed up. The movie is still there (as confirmed by trying to actually download another that was larger than the current free space, then the previous movie file was indeed deleted by iOS automatically) but it does not show up in usage > videos. According to iOS the Videos.app has no data within.
    I'll try a full reset soon and see how it goes. Obviously it will take some time to test it, but I'll let you know of any results. Luckily, I don't have many apps that don't use iCloud storage so their data should be there despite dropping the backup, and installing them clean should be easy using iTunes on a PC.
    If that doesn't help, I go one step further and download the apps one by one.
    Well, there is plan.
    To be honest, it would really be helpful if we could see individual app containers as that way we can easily find out which app is being naughty.
    Any way, thanks for the tip! Give me a couple of days and I'll let you know how it went.

  • URGENT-Does Erase all Data and restoring from a previously made backup permanently delete text messages after that backup??

    Does restoring from a previously made backup permanently delete text messages after that backup?
    I made a Icloud back up two days ago. I have text messaged and sent emails since. I haven't backed up again yet and I was wondering that if I erase my phone and back up to that Icloud Back up made two days ago, the texts and emails I have sent SINCE then will be permanently deleted? AKA they can never be found again by anyone?

    That is correct you can only get back data that was backed up.

  • Best way to clean all data n8

    Solved!
    Go to Solution.

    Enter *#7370# followed by the security code which is 12345 by default. You must have a SIM inserted for this to work I believe (been a while).
    This will erase all data and restore settings to factory defaults.

    Although not illegal, Apple discourages a user from modifying the iPhone OS in any manner, including "jailbreaking".  Apple feels so strongly about this that discussing methods to assist a user trying to either jailbreak or "unjailbreak" an iPhone are prohibited.

  • My friend borrowed my old iPhone 4. I wanted to erase all the data but I dont have a password and my friend doesnt know his password. How can I erase the data without using a password?

    My friend borrowed my iPhone. I want to sell the iPhone, but first I have to erase all the data that belong too my friend. I don't know his password and he doesn't know either. Is it possible to erase the data without using a password?
    thanks!

    You need the password if it is iCloud locked you won't be able to activate the phone for use.
    As long as he remembers his email,  you can reset the password
    If you forgot your Apple ID password
    or Forgot Apple ID
    https://iforgot.apple.com/appleid
    If it is a lock screen password, you can do a restore.
    Hold down power and home for 10 seconds and release power but keep holding down home. iTunes will say your phone is in recovery mode so you can restore it.

    You have to restore the iPod, no ifs, ands, or buts...
    After iOS is installed you will be asked if you what to set it up as a new iPod or if you want to restore from a backup.
    If you have a good backup you can restore that and you're good to go.
    If you don't have a good backup, then you end up with a "clean" iPod....

    I have the same problem as the emails go to my iCloud account that I cannot access!!! I cannot answer the security questions as someone else must have set up my iCloud account. Nothing seems to work. It would be great if someone has some ideas as what can be done to recover the situation?

  • I am giving my old MacBook Air to my granddaughter.  What is the most efficient way to erase all the data on it?

    I am giving my old MacBook Air to my granddaughter.  What is the most efficient way to erase the data?

    You have two options.....
    One is to do a clean reinstall of your OS - if you still have the USB installer that came with your Macbook Air...
    The second option is to create a new user (your granddaugher's name).....Deauthorize your Macbook Air from your Itunes and Appstore.....
    Restart your Macbook after you've created your granddaughter's user name, login under your granddaughter's username and delete your username.
    Search your Macbook for your old files and delete them.....
    Good luck...

  • Had many issues with phone, decided to erase all data and now it won't finish

    Okay here's the rundown of my problem on my iPhone 5 32GB. I can't check currently (you'll understand why later) but I believe it was on iOS 7.1.1 as I know it wasn't the absolute most recent version. First off, my lock button is sometimes unresponsive, a hardware issue and I haven't gotten around to getting that fixed yet. Anyways.
    Today I wanted to open up my twitter app. The instant it opens, everything freezes. I mean everything: screen, lock button, home button, everything. The screen usually shuts off after 90s if I don't do anything, so the screen went black after this time as everything I did didn't register. Now with the screen being black, still no response from most things. The only thing I can do is activate Siri, though the screen still doesn't turn on, just the sound. She couldn't usually hear me, and if she did it would take her about a minute or so to respond. I can still connect to iTunes (windows 8) though so I did that, but I stopped the initial sync. I tried doing the hold both buttons for 10s thing but that didn't work (might be because the lock button is iffy) so I couldn't start recovery mode.
    At this point, I decide the only thing I could do (because no where on Google anyone had a similar problem) is to restore the phone, either to factory or to a backup. When I tried these options in iTunes, it told me that it could not do this while Find my iPhone is active, and to go to settings on my phone to turn it off. I can't open settings with the screen black. I tried going to icloud.com in order to see if I could turn it off from there. The site could find my phone just fine, could make the sound just fine. I could however not remove the device from iCloud unless the phone was turned off (which I again can't do with a black screen).
    At this point, I went to the directory with the backup on my computer and copied it to another location. Then in iTunes I did a sync to create a new backup. Now the only thing that was available for me to do was on the web site to erase all data from the phone as it did not require Find my iPhone to be turned off. Feeling out of options, I went through with it and clicked erase. For some reason, this is the time that the screen decides to turn on. The phone showed the apple logo and a progress bar. The bar progressed quickly at first but then slowed as it neared the end. At this current point, it's been at what appears to be 100% for around an hour with nothing happening. The buttons do nothing, my computer can't see the device so iTunes won't do anything.
    Is there anything else I could try to do or should I just wait it out. My city does have an apple store which I could go to tomorrow but if I could get my phone running tonight that would be great. Also, if I can't do anything and it doesn't budge, if I take it to the store would it cost a lot to fix or (if necessary) replace? It was a birthday gift two years ago, bought without a plan, and I don't think it's still under warranty.

    Hi..thanks for your advice!
    Ok, I am student so buying a new phone is not possible ;( This experience has turned me off Apple anyway! All I did was click yes to their iTunes upgrade prompt asking me if I want to update....and now I don't have a phone and can't access all my backup etc on my iTunes because it seems the only way to get to it is with another iPhone!?
    I can't believe that through the Apple recycling program I could possibly get $50 for this phone because the hardware is perfect but there is no support for this issue...feels like Apple is just trying to force everyone with hacked phone to buy new ones!
