OK Guys,here is a easy guide on how to flash a recovery image to your ALREADY ROOTED android phone using an app called TERMINAL EMULATOR.this is very easy if you follow my directions without mistake. (terminal emulator is case sensitive,so ONLY use capital letters if there is a capital letter in the name of your recovery image.if you follow my directions,this wont matter)
you will need to be rooted already or this wont work.
download terminal emulator off the market.
Download the Recovery Image and Flash Image.
step 1:name your recovery image, "recoveryimage" for simplicity sake,and place it on the root of your sd card. (root of sd means,dont put it into a folder) ALSO,place the FLASH IMAGE on the root of SD also.
step 2: open terminal emulator and type "su".(do not include quotation marks)
you will get the superuser request pop-up.hit allow.then you should see a # appear.
step 3:type this exactly how i type it.if there seems to be a space,there is one.
cat /sdcard/flash_image > /system/bin/flash_image
hit enter,then type the below line
flash_image recovery /sdcard/recoveryimage.img
Once you enter that command,your all done..to get into recovery,power off the phone.hold home,vol down and power until recovery shows up..hope this helps and remember,hit the THANKS button!
Now if the terminal emulator method isnt working for you,try it this way...
You will need to still download the recovery and flash.img and place it in the root of the SD card (meaning not in any folders)
1. Install android SDK..after UNZIPPING IT TO YOUR C DRIVE,open the exe. once it opens,it will ask to install optional packages,DENY ALL EXCEPT PLATFORM TOOLS...after the PLATFORM TOOLS is done installing,close out everything.
1.5. Navigate to the android-sdk-windows/platform tools/ folder..hold shift then right click inside the platform-tools folder..select "open command window here".when it opens,type "adb shell" then hit enter..if you get a $ symbol,skip to step 5. otherwise resume to the next step.
2.now that you have the platform tools installed,go to the start menu,right click on my computer,then select properties. on the left side of the screen,select "advanced system settings". A window will pop up and at the bottom of it you will see "environmental variables"..select it.. now under system variables,scroll down to "path"..select "path" and hit the "edit" button...
3.Now,(WITHOUT ALTERING THE EXISTING CHARACTERS THAT ARE ALREADY THERE) COPY+PASTE the below string into the END of the "path" section.
;C:\android-sdk-windows/platform-tools;
4.now hit save and exit out of every thing..hit the start button and in the search bar at the bottom,type,"cmd" and hit enter.the command prompt will open.now when it opens do the following..
type- adb (hit enter and a bunch of text should appear and scroll down the screen)
type-adb shell (it should now say *daemon not running,starting it now on port 5017*,then under it, it should say *daemon started successfully*).if your phone is not plugged it,after daemon started it will say,error device not found..thats normal..if your phone IS plugged in,after daemon started,it should display a $ symbol. if you got the $,then go to the next step.....if you still have devices not found,plug in your phone with usb debugging ENABLED (its in settings/applications/development/).once its plugged in,enter "adb shell",hit enter,now you should have $.
5.type "su" .then your phone should ask for superuser permission (make sure the screen is on) hit allow.now instead of a $,you should now have a #...now go to the last step.
6.copy and paste the following commands into the terminal,(assuming the flash.img and the recovery.img is on the root of the sd card)
mount -o remount,rw -t yaffs2 /dev/block/mtdblock5 /system
cat /sdcard/flash_image > /system/bin/flash_image
chmod 755 /system/bin/flash_image
mv /system/etc/install-recovery.sh /system/etc/install-recovery.sh.bak
mount -o remount,ro -t yaffs2 /dev/block/mtdblock5 /system
flash_image recovery /sdcard/recovery.img
once you hit enter after the LAST command,close everything out,unplug your phone,power it off..now while off,hold home+vol down+power,until recovery pops up (about 10 seconds-ish)
