[Samsung Infuse 4G] Fullmetal Jun:
Good luck

Please go and learn the unbrick Odin to stock GB with root guide first.This it's your key!

The unbrick tool guide mentionned in the previous replies is the working and proven tool, but first you must be in download mode.

It's a must to FIRST download and install Samsung Kies on your PC for the drivers or else your phone won't connect (vol Up,vol down simultaneously together while connecting to PC via USB)

Follow the Odin guide in the previous reply step by step and with a cool mind.Don't stress!!!

Try searching for the real download mode procedure as I forgot it.It's found in the unbrick guide mentioned.

If you still can't be in download mode, search the Web a lot and try to do this:

Let your phone battery die out (leave the screen on till it dies or try restarting a few times to let it die.Remove battery.

Forget the phone for a whole day.

Then try to put it back to download mode on your PC.No need to put battery back.The phone will switch on!

But first learn the unbrick Odin to stock guide as it's the whole key to your problem!

If you succeeded, then here is your first step to flash a ROM.

This is a thread for a working CWM on infuse.I used the 04.30 1.2GHz version and you can install it without going into recovery mode using SGS Kernel Flasher in play store for free:

I followed the above instructions and upgraded the Samsung galaxy infuse 4G from gingerbread 2.3 to Android Jelly Bean 4.3.

It will be difficult for you to do unless you know computers well. You will need 1 to 3 hours to complete.

Every single little step must be followed, pretty much fill in every single step.

First you must obtain CWM, it's a flashing utility which is accessed at boot up by holding Volume up + volume down + power

Phase 1:

---------

To obtain CWM head over too Jscotts odin url.

1. download the file which includes root access.

"Stock UCLB3 with root

UCLB3_Unbrick_root_1.1.zip"

2. you will also need Samsung Kies, which will install the usb driver for your Samsung galaxy. The link is on the website.

3. Place your phone into Download mode

To do this, have your usb cable for your phone plugged into the computer but disconnected from your phone. shut off your phone. When the power is off press Volume up and Volume down simultaneously, after the buttons are pressed plug in the usb cable at the same time, which should be connected to the computer.

This will place the phone in Download mode.

4. open the included Odin.exe, when you see the yellow bar under ID:COM then everything is good.

Follow the rest of the instructions on jscotts website.

Finally when this procces is done, reboot into android.

Phase 2:

---------

1) Download SGS kernel flasher

2) Click on the link on jscotts website to download a stock kernel which contains CWM. use "2013.04.30-CWM-Synthesis-1.2Ghz.zip

Phase 3:

----------

description:

Convert the phone from gingerbread 2.3 to ICS Android 4.0, as the instructions say.

Head over too: Entropy's CM9 website:

forum.xda-developers.co...hp?t=1601844

1) There are 3 links on the website for Cynogen 9 rom for Samsung infusion 4g, any one is ok. Download CG9 for Samsung infusion 4g. version along with the Gapps.

2) After saving both zip's on your sd internal memory, shut off your phone. Press both volume up and volume down and power at the same time.

The phone will boot into CWM.

3) Make a backup of your original rom for your phone before proceeding.

4) Select Flash zip, select your ICS android 4.0 rom which you saved on your internal sd. (ie: "cm-9-20120620-UNOFFICIAL-infuse4g.zip";)

5) Install GAPPS as well, after step 4 is complete.
