Update and Jailbreak iPhone 3G
and iTouch 2G 4.2.1 using the
latest redsn0w
This TUT is for iPhone 3G and
iTouch 2G users who wants to
update to 4.2.1 firmware and
jailbreak untethered. The
difference with this TUT from the
one that I made a month ago is
that you will be using the latest
redsn0w in jailbreaking your
device. The latest redsn0w is
faster and safer in jailbreaking
compared to earlier versions,
however I haven't tested the
automatic, mode only manual on
older devices.
iOS Firmware 4.2.1 is the last
firmware released by Apple for
iPhone 3G and iTouch 2G.
Unfortunately the multitasking
and Homescreen Wallpaper
features are still disabled due to
hardware limitations. Although,
jailbreaking enables it,
personally I don't recommend
enabling it because it will slow
your device's overall
performance. Gumawa rin ako
ng TUT on how to make your
older devices faster on 4.2.1 with
some tweaks. Links are at the
very bottom.
Requirements
- iPhone 3G or iTouch 2G
- 4.2.1 Stock IPSW (For Manual
Jailbreak Option B)
- latest redsn0w
- Internet Connection
- Windows XP/Vista/7 32-Bit
Please backup and sync your
device to iTunes or you'll loose
everything.
Disclaimer: I am not in anyway
responsible for anything that
will happen to your device or
be held liable for any lost of
files and personal data. Your
device is your sole
responsibility, and it is by your
own will that you chose to
jailbreak it.

Note: screenshot below might
show an older version of
redsn0w however interface is
just the same with the latest
one.

Update Instructions
1. Download 4.2.1 Stock IPSW make sure
to choose the correct IPSW for
your device.
2. Connect your device to the
computer and open iTunes.
3. Click your device and go to the
summary tab.
4. PRESS and HOLD the SHIFT
KEY on your keyboard and click
RESTORE.
5. Look for the stock 4.2.1 IPSW
file that you downloaded and
open it.
6. Wait for iTunes to finish the
update process.
Jailbreaking
Option A (Automatic)
Automatic jailbreak is process
wherein, redsn0w will detect the
firmware of your device and
download the necessary files to
jailbreak it without the need of
the large stock IPSW file.
Note: Please provide a feedback if
the automatic method works or
not because I haven't tested this
method on older devices only
newer ones, and for me to
remove option A from this post.
1. Connect your device to the
computer and make sure that
you are connected to the
internet.
2. Download redsn0w 0.9.14.b2
from the link below.

3. Click JAILBREAK
4. Follow DFU instructions
5. Possible Error: redsn0w
identified that you are using an
older device and it is
unsupported, if none proceed
with the next step, otherwise go
to Option B for the manual
jailbreak.
6. Wait for redsn0w to verify,
download and run the exploit on
your device. You device will
reboot once and wait for the
ramdisk to finish
7. Check the following boxes
shown on the screenshot below.
iTouch 2G users you won't see
the ipad baseband. It is your
choice to enable multitasking and
homescreen wallpaper, but, just
like I said, it will affect the
overall performance of your
device. It will slow down your
iphone and itouch.
8. For 3G users it is required to
install the iPad baseband for
your device to be unlocked using
ultrasn0w. Click YES on the pop-
up windows.
9. Click NEXT
10. Wait for the jailbreak process
finish.
11. Congratulations! Your device
is already jailbroken!

apple.

computer.

administrator
3. Click EXTRAS

Stock IPSW that you downloaded.

redsn0w while it prepares the
jailbreak data.
9 . Check the following boxes
shown on the screenshot below.
