The complete step-by-step guide to rooting your Android phone: " Android

This tutorial will guide you every single step of the way through the process of rooting your Android phone, and installing the Cyanogen ROM.

I’ve created this guide by using several other sources I found online. None were (in my opinion) as comprehensive and easy to follow as this one.

If you’re wondering why you’d want to root your Android phone, give Lifehackers Five great reasons to root your Android phone a read.

It should be noted right up front: following the steps in this tutorial may void the warranty on your phone. All of your settings and applications will be wiped out (but the data on your SD card will remain intact).

Note: the steps and screenshots in this tutorial are specific to the HTC G1. It’s my understanding that this process will work perfectly fine with the myTouch 3G, but I cannot personally confirm that, as I don’t have one.

Here goes:

Start out by plugging your your phone into your PC via USB. Once it’s connected to your PC, you should see a small USB icon in the upper left corner of your phone. Drag the “menu bar” down and there will be an entry titled USB connected. Tap (or click) it.

Now tap the Mount button.

In your browser, visit this page and download the latest stable release of CyanogenMod. The file will be in the format of update-cm-x.x.x-signed.zip (make sure to download the zip file and not the md5sum file). At the time of this tutorial, update-cm-4.0.4-signed.zip was the latest CyanogenMod. Use the date column on the right side of the page to determine which one is the latest version.

Once you’ve downloaded the file, copy it to your Android’s SD card. The SD card can be found by going to My Computer and locating the drive that represents your SD card.

After you’ve copied the CyanogenMod .zip file to the SD card on your phone, slide down the menu bar again and this time tap Turn off USB storage.

You’ll be prompted with a Turn off USB storage window – tap the Turn Off button.

Now open the browser on your Android phone. Enter the URL http://ryebrye.com/files/flashrec.apk.

The file is just about 4MB in size, so it might take a minute or three to download.

Once the download has completed, tap the download entry for that file.

If you haven’t previously enabled installing 3rd party applications, a warning window will pop up. Click the Settings button on that screen. Note: if you have previously enabled installing 3rd party apps, skip down to step #12.

The Application settings window will open. Tap the ‘grayed out’ check mark next to the Unknown sources entry (so that a green check-mark appears).

Tap OK on the warning window.

Use the Back button to return to the downloads list. Now tap the download entry for flashrec.apk again. This time you’ll be prompted to install it. Click the Install button.

Once the installation has completed, tap the Open button.

On the Recovery Flasher window, tap the Backup Recovery Image button.

Let the recovery flasher do its thing. It’ll only take a few moments.

Once the backup has completed, you should be presented with a screen that says Backed up. at the top. Now tap the Flash Cyanogen Recovery 1.4 button.

Once this process has completed, you’ll be presented with a screen that says Flashed new recovery image. at the top.

At this point you need to power your phone off. Hold down the power button and select the Power off option.

Tap OK to shut your phone down.

Hold down the Home button and click the power button to turn your phone back on. It’s very important that you hold down the Home button when turning your phone back on or Android will over-write the recovery image that you just installed.

When Android powers up, you’ll be presented with a new screen – the Cyanogen recovery image. Use your trackball and navigate down to nandroid v2.2 backup. Click this entry with the trackball.

Cyanogen will now create a recovery image for you. This is very helpful if you ever need to restore your Android phone. Don’t skip this step.

Once the backup has completed, you’ll see a screen with Backup complete! at the bottom.

Now scroll down to the entry titled wipe data/factory reset and click it with your trackball.

You’ll be asked to confirm this action by clicking the HOME button on your phone. Do so now.

Cyanogen will now wipe your Android phone. Once this process has completed, scroll to the apply any zip from sd entry and click it.

Select the .zip file that you copied to your SD card way back in step #3. Again, this file should be titled something like update-cm-x.x.x-signed.zip. Once you’ve selected that file, click it (using the trackball-button).

Click the HOME button to confirm this action.

The process of applying the CyanogenMod can take a couple of minutes to complete, so don’t worry if nothing seems to be happening.

Once it says Install from sdcard complete at the bottom of your screen, scroll to the reboot system now entry and click it.

Your phone will now restart. You’ll notice that the boot screen is slightly different now. This is a good sign.

Once your device finishes starting up, right away you’ll notice a new background image.

If you’d like to confirm everything installed, open your Settings, scroll down to About phone and select it. There should be a new entry in that list titled Mod version. It should say CyanogenMod-x.x.x (where x.x.x is the version you downloaded and installed).

Once again mount your SD card in Windows (see steps #1-3 above). There should be a new file on your SD card titled recovery-backup.img. Copy this file to your PC. This is the backup that you created in step #14, and it’s very important and helpful to have if you should every decide to restore your Android phone. It’s also a good idea to copy this file elsewhere – to your online backup service, a DVD, an external drive etc. You may even want to email a copy to yourself if you use an online email service like Gmail, so that it will always be stored on the Gmail servers.

That’s it! You’ve now rooted your phone and installed the CyanogenMod mod. Explore your Applications and phone – you’ll notice a number of new apps and features. One of which is that you now have 5 ‘home’ screens instead of 3. You should also notice that your phone is considerably faster – one of the main reasons to go through this process.

Water powered cable trains: "

Cable
trains (or funiculars) are one of the most energy-efficient modes of
transport out there. A large portion of the power required to pull up the ascending
car is delivered by the counterweight of the descending car. Many
historical systems used this efficiency and took it one step further with systems exclusively powered by water and gravity.

----------------------------------------------------------------------------------------------------------------------------------------------

Cable trains first appeared within the second half of the 19th century. Many of them have survived and continue to be utilised
(mostly in a modernized form) and new systems are being developed. A cable train system is operated on a steep slope with a
gradient of up to 55 percent and consists of two passenger cars which are
connected by a steel cable. Both cars travel on the same single track,
which is undoubled in the middle so that they can pass each other.

Cable trains prove extremely energy efficient because a large share of the power
required to pull up the ascending car is delivered by the counterweight
of the descending car. Since the system only needs one track and can go
straight up a mountain, it also saves a lot of materials and space (some systems use
two tracks but follow the same principle).
A funicular should not be confused with a cog wheel train - even though
many older cable cars applied a similar mechanism, as a braking system and speed governor, not as a traction
method.

Water powered cable trains

Originally, cable train systems were even more energy-efficient than they are
today. Instead of using an engine to pull the cable, the extra power
required to overcome friction and to pull up the ascending car was
delivered by filling the water reservoir of the upper car (see an
example of the mechanism below).

Before
departure, the employee in the upper station was informed of the number
of passengers that had entered the ascending car. He then knew exactly
how much water the reservoir of the descending car should contain
(around 80 litres per passenger).

From the moment the
descending car became heavier than the ascending car, the brakes were
loosened and both cars were set in motion powered solely by gravity.
Once the descending car arrived, its water reservoir was emptied and
the process was repeated.

Most cable trains using water counterbalanced energy have been replaced
by systems that utilise engines. One famous example is the Funiculaire de Montmartre in Paris, France,
which was operated by water power from 1900 to 1930 and
transported one million passengers per year (illustration below).

Thankfully, a few water powered cable cars continue to be in service, and have remained so for over a century. The Elevador do Bom Jesus in Braga, Portugal, has been in use since 1882. The Nerobergbahn in Wiesbaden, Germany, has been working since 1888, the Lynton & Lynmouth in North Devon, UK since 1890, and the Funiculaire Neuveville-St.Pierre in Fribourg, Switzerland since 1899 (see picture intro, note the water filling system on the side of the car).

Perpetuum mobile

Most water powered cable cars
require energy to operate the pump that transports the water up the
hill again, so of course, perpetual motion does not exist. There are however some exceptions to this. The 120 metre track in
Fribourg, Switzerland, operates without a pump.
It makes use of the natural flow of water along the track, more
specifically the waste water infrastructure which connects the upper
and the lower part of town.

How it works is this (illustration above, source):
The
waste water flows into a reservoir of 100,000 litres. From there it
flows in the water tank of the rail car . Around 1,500 litres of water
is required to pull up the other car from 60
meters below, and it takes 3 minutes to fill up the tank. After
approximately 1.5 minutes, you will have arrived at the ground station.
The reservoir is
then emptied and the water continues its way downwards through the
sewer
system. The train route was designed as a (very creative) way to lower
the flow of the fountains in the lower part of town.

Gravity

To add to this, in
the case of the Lynton & Lynmouth Cliff Railway, no water is pumped
from the bottom to fill the tanks at the top station - the water is
taken from a nearby river. Moreover, at this track the method is reversed.
Both car tanks are full of water, the tank of the bottom car is
partially discharged until the bottom car becomes lighter than the top
car, and gravity takes its course (source & more info). The Centre for Alternative Technology built a similar system in 1992 with a lake at the top of the mountain supplying the railway with water.

The
main disadvantage of a water-balanced railway (just like any other use
of hydro power) is that it cannot be operated when the water freezes
over. Bummer.

You need a mountain as well, of course.
