How to restore a Galaxy Note 2 from rooted to factory settings

Had enough of customised Android? Or has your Note 2 been bricked while you've been tinkering with it? You've come to the right place.


So, you've been tinkering with our favourite custom ROMs for the Samsung Galaxy Note 2, but oh no! Something's gone wrong and you've ended up with a bricked phablet? Or perhaps you've just had enough of customised Android and want to go back to the stock ROM the phone came with? Either way, you've come to the right place.
If the Note 2 is bricked, you may still be able to get it up and running again using this guide. As long as you can boot into download mode, there's hope.
As per usual though, it should go without saying that tinkering with your phone like this isn't something that Samsung or your mobile network will be terrible happy about. CNET accepts no responsibility for things going wrong (or any more wrong, if you're already bricked). Got it? Grand.
Right, ready? Let's get cracking...

1. Backup!

If your phone isn't bricked, this is simple enough: backup any texts, photos, notes and so on before you begin. There are various handy apps for this on Google Play, and photos can just be dragged and dropped on to your PC. Contacts, of course, are synced with your Google account anyway, so assuming you're logged in you don't need to worry about these.
If it is bricked and can't boot your phone, you'll just have to accept some losses are possible, but you can at least get anything off your SD card if you have a card reader, or another phone.

2. Find that ROM

First, you'll need to download the Note 2 stock ROM. This article assumes yours is a UK model, the GT-N7100. If your phone isn't bricked, you can double-check this by going into the settings of your phone, and scrolling down to 'About Device'. Tap into that and scroll to Model Number -- if it's GT-N7100, you're golden and we can carry on.

Here's the stock ROM for the GT-N7100 flavour of Note 2. It weighs in at a whopping 1GB in size, so you may be waiting a little while for it to download.
While it's doing that, don't just twiddle your thumbs: make sure you've downloaded the Odin tool, and have the Samsung USB drivers installed.
To be clear, you should have both of these already if you need to return to the stock ROM (otherwise it's a mystery how your phone was bricked by a custom one), but I thought it best to cover it anyway. Besides, you've got nothing better to do than get this recap if your download of the stock ROM is going anything like as slowly as mine.

3. Back to stock

Once everything is in place, unzip the stock ROM and make a note of where you put the file within. It tips the scales at 1.42GB unzipped, so it shouldn't be easy to miss.
Odin prepared
Open up Odin, press PDA and select that 1.42GB file, named N7100XXALJ1_N7100OXXALJ1_N7100XXALIH_HOME.tar.md5, which you may want to make a note of as a beautiful name for a child, or pet. 'Auto Reboot' and 'F: Reset Time' should be ticked, but everything else should not be. It was like this by default for me.
Galaxy Note 2 download mode
Boot your Note 2 into download mode. You do this by holding down Power, Menu and Volume Down (not Volume Up -- that's a whole different kettle of fish). You'll see a warning about the dangers of custom ROMs, but you know about that already, right? Now press Volume Up to continue.

(Apologies for the shaky photo -- if you've done this yourself you might be able to relate to my quivering hands.) The image on the screen will turn to a green android with the caption, 'Downloading... Do not turn off target !!'. Connect your Note 2 to your computer with the USB cable. Odin will react to this -- the ID:COM box in the upper left of the screen will turn yellow, and you'll get a message saying 'Added!!' in the message box in the bottom left. You can now press Start, and let the ROM installation begin.
Odin added
Once that's done -- it'll take a good few minutes, but there's a status bar to keep you company -- the phone will reboot itself, with the familiar Samsung boot screen. It'll probably take longer than you're used to, so be patient.

If after 10 minutes it still hasn't loaded, something's probably up. Reboot the phone into Recovery Mode by holding down Power, Menu and Volume Up (Up this time, not down) and scroll down to 'wipe data/factory reset', and select it. Reboot the phone and hopefully you should be good to go this time. (This did the trick for mine.)

4. Done!

Galaxy Note 2 bootup
Aaaaand we're back! There's the familiar sight of your Note 2 asking you to select a language. Now you'll just have to connect to your Wi-Fi and log back into Google and Samsung (if you want to), and then start the thankless task of getting your phone setup just how you like it all over again.

That's it -- you're done, back with a Samsung Galaxy Note 2 with the stock ROM as nature (or Samsung at least) intended. This means that if you want to customise it again, you'll need to go through the root procedure again. Here's a handy recap if you've forgotten how.

How to set up a smart garden for free

You can use the free Koubachi application to get all of the care advice and email reminders you need to keep your plants flourishing without paying a penny.


The price of connected plant sensors lessens the lure of the smart garden for many cost-conscious consumers. Yes, it would be cool if technology could give your plants a voice, make care recommendations, and send you reminders, but why would you want to pay $60 to $120 to monitor a houseplant that you only paid $10 for in the first place?
Fortunately, you can set up a smart gardening system, complete with reminders and recommendations, and it doesn't have to cost you a penny. Here's how you can use the Internet to help you care for your plants for free.

Get a free Koubachi account

A couple of weeks ago, I reviewed the Koubachi Wi-Fi Plant Sensor. The device worked well, if a bit slowly, but I still felt the high cost was hard to justify. One reason for this was the capability of the Koubachi app, which, with a little more setup on your part, can do just about everything the sensor could, without having to pay for the sensor. Thus, the Koubachi app is the key to free smart gardening, and I'll walk you through what that setup looks like.
You can download the Koubachi app for iOS or Android, you can also sign up on the website and access the same system from any Web-enabled device.

Identify your plant

Once you have the app up and running, you can use Koubachi's system to help you identify the plant or plants you'll be monitoring. If you know your plant, skip this step and search the database by name. If not, you'll have the easiest time with the beta version of Plant Finder on the iOS app. Plant Finder will guide you through the process with step by step questions and pictures, and you can skip any questions you don't know. For a novice, it's the easiest way to identify your plant out there.

Unfortunately, it's not yet available for the Web-based platform or Android. The Android app will limit you to browsing pictures and searching by name. On the website, you can narrow your choices by stem and leaf criteria.

Temperature, light, misting, and fertilizer

Next, you'll want to pull up the info Koubachi has on your specific plant. There, you'll find its preferences for sunlight and temperature in specific and understandable terms. Now you'll know if your plant likes direct sunlight, shade, or anything in between. The info will also list the ideal temperature ranges for your plant in both summer and winter. Follow these basics when deciding where to place your plant, and you're done with temperature and light.

For upkeep with misting and fertilizer, Koubachi will give you scheduling recommendations right away, based on your specific plant. My giant yucca didn't require misting, but Koubachi instructed me to give my coffee plant a full misting every four days. Similarly, the system will tell you how often to fertilize and the type of fertilizer to use.

Customize reminders for these tasks, and you'll start receiving emails when your plants need something. Just make sure to tell the system when you've misted or fertilized so it can update the schedule for you and keep the reminders accurate.
Within a couple of minutes of downloading the app, you'll have light, temperature, misting and fertilizer covered.

Calibrate a watering schedule

Finally, you'll need to help Koubachi with the last and most important piece of day-to-day upkeep: watering. Koubachi needs to know how long it takes the soil around your plant to dry out after you've watered your plant. Once it does, it'll remember that time frame and send you reminders for this as well.
Koubachi calls this learning process "calibration," and it's as simple as the rest, but it does take a little more time. Start by fully watering your plant. If you don't know how to fully water your plant, Koubachi can give you more detailed instructions, but you'll have to manipulate the system a little to see these. When you first start calibrating, Koubachi simply tells you to water, no specifics provided. To get these details, tell the system the plant is dry. It'll be surprised this happened so quickly and ask if you're sure. Confirm, and it'll schedule your next watering, complete with the exact watering instructions for your plant.

Now, restart the calibration. Getting these specifics is more of a pain than it should be, but if you need the help, it'll really only take an extra minute or two.
Once your plant is watered, you'll need to check the soil moisture regularly. For a sensitive plant, check daily. Most of the time, checking every other day will be fine. Don't worry -- Koubachi will send you reminders for the calibration process as well.
To check the moisture, take a pencil and insert it an inch into the soil. When you pull it out, dirt will stick to the pencil if it's still wet. Once its dry, the dirt will fall right off as you pull the pencil from the soil. Update Koubachi, and you'll have a set watering schedule. You can even adjust the schedule as necessary if you have an outdoor plant. Just tell Koubachi whenever you water or if it rains. It'll keep the same reminder interval and simply shift it accordingly.

If you like Koubachi's app and don't want to calibrate yourself, paying for $99 for the indoor sensor or $129 for the outdoor version can provide added convenience. Alternatively, the PlantLink from Oso Technologies costs $79 and can take care of the moisture part for you.
However, if you're willing to help Koubachi calibrate, you can setup connected plant care, get advice on temperature and light, and receive email reminders for misting, fertilizing, and watering, all for free.
