1. HOW TO INSTALL TWRP RECOVERY :

FOR ANY AND ALL STOCK FIRMWARES OR CUSTOM ROMS

NEWBS: READ THE WHOLE POST X2 B4 YOU PROCEED.

1. GETTING PHONE INTO DOWLOAD MODE(aka odin mode):

AT NO TIME IS THE POWER BUTTON TOUCHED FOR THIS PROCEDURE.

Download mode is NOT the same as recovery mode

a. Remove and Reinsert the battery, have usb cable inserted to computer usb port but

NOT

to your phone until step (c).

b. ATT PHONES - Press and keep down both Volume Up and Volume Down buttons simultaneously.

ROGERS PHONES - Press and keep down only the Volume Down button.

DO NOT RELEASE THE VOLUME BUTTON(S) UNTIL INSTRUCTED TO DO SO IN STEP (d)

c. While still holding the volume button(s) down insert the USB cable into your device.

The phone will turn itself on when usb cable is inserted.

* KEEP VOLUME BUTTON(S) PRESSED - DO NOT TOUCH THE POWER BUTTON *

d. When You see the screen warning you about installing a custom OS w/a yellow triangle RELEASE the volume button(s)

e.

1ST PIC: Now press and release the volume "up" button, you should now be at the Download Mode screen w/odin recognizing your phone.

2ND PIC: this is also download/odin mode - the screen will display this when odin or kies has failed/not completed a previous flash, just continue following the procedure and/or read "section #3 troubleshooting odin" below.

1ST PIC >> ....

2ND PIC >>

2. DOWNLOAD twrp-3.0.0-0-skyrocket.tar.md5 - DO NOT CHANGE THE FILE NAME.

3. DOWNLOAD Odin-1.85.zip , Extract the contents of odin-185.zip to a folder, within that folder start "Odin3 v1.85.exe" .

4. Prepare Odin: Check "auto-reboot" and UNCHECK ALL OTHER OPTIONS.

Only Click "PDA" and navigate/select the TWRP tar.md5 file you downloaded from step #2.

DO

NOT!

CHECK "REPARTITION" IN ODIN! YOU HAVE BEEN WARNED!!! SEE COMPUTER SREEN PICS BELOW.

ON YOUR COMPUTER THIS IS WHAT YOUR SCREEN MUST LOOK LIKE WHEN YOUR PHONE IS IN DOWNLOAD MODE AND ODIN IS RECOGNIZING YOUR PHONE

BEFORE

YOU HIT THE START BUTTON.

5. Click Start in Odin. It will flash the new recovery and will reboot the phone when completed.

ON YOUR COMPUTER THIS IS WHAT YOUR SCREEN MUST LOOK LIKE WHEN ODIN HAS FINISHED FLASHING YOUR PHONE

IF YOU HAD ERRORS OR PROBLEMS USING ODIN, GO TO SECTION 3 - TROUBLESHOOTING ODIN

If All Went Well Then You are done using ODIN.

6. UPDATING TWRP

How To Enter Recovery Mode Is In Section #2 Below

Do Not Use Odin To Flash "Zip" Files.

LINKS TO RECOVERY ZIP FILES ARE IN THE 1STOP THREAD

TWRP

Read The TWRP THREAD To See If New Updates Have Any Bugs

PREFERRED METHOD: You can use a flashable zip file to be used by TWRP recovery, check in the 1STOP STICKY in the recovery section for latest files, copy the "zip" file to your sdcard and install it via the custom recovery and reboot back into recovery to see if it installed correctly.

ALTERNATE METHOD #1: TWRP now has odin flashable tar files , check HERE for latest TAR FILE to be used by ODIN. - WARNING - these are not tar.md5 files so check the HASH before flashing

ALTERNATE METHOD #2: using img files read this

7. You're done newbie and soon to be a power user,

read and educate yourself

as much as you can before flashing, happy flashing. :fingers-crossed:

2. HOW TO ENTER INTO THE RECOVERY MODE

ENTERING IN TO RECOVERY MODE IS THE SAME METHOD FOR BOTH ATT AND ROGERS SKYROCKETS.

ENTERING IN TO RECOVERY MODE IS THE SAME METHOD FOR BOTH STOCK AND A CUSTOM RECOVERY.

RECOVERY AND DOWNLOAD(ODIN) MODES ARE NOT THE SAMETHING

Now turn off your phone, unplugged(might work plugged in)

Press and keep both volume keys down

Then press the power button while still holding down the volume keys

When you feel the phone vibrate or see a logo on the screen, release the power button but not the volume keys.

When screen goes black release the volume keys.

Wait a few seconds to boot in to recovery

You are now in recovery mode

.

3. TROUBLESHOOTING ODIN

If Odin Shows An md5 Error Redownload The File Again

If Odin hangs at "Getting PIT for mapping" or giving a pit error - Read This Thread and post number 15 for solution

If the phone boots into any rom, make sure windows can transfer from and to internal and external sdcards to rule out driver issues

Does kies recognize your phone, even if you are on a custom rom kies will recognize your phone, this rules out driver issues

Make Sure You Are In Download Mode On Your Phone

If having trouble getting into dl mode try this>> take out the battery and leave it out. Plug the phone into the micro usb cable. Plug the USB end into your comp. Hold volume rockers down(either both or vol "-") and reinsert the battery

Make Sure Kies, Adb Or Anything That Has Usb Access Like Vm's Are Not Running In The Background or Running As A Service - Check With Windows Task Manager.

Restart computer

Make sure battery is charged

Try different usb port, preferably the rear ones on computer

Use original samsung usb cable, or try different cable but still oem

Uninstall drivers and kies, unplug phone & reboot comp, then just reinstall the USB Drivers from here

Try a different computer

Clean phones usb port w/no battery installed

If Phone Boot Loops Or Enters Into Recovery Mode While Trying To Get Into Download Mode(and you are sure you followed above procedure and also did not touch the power button), You Could Have A Stuck Power Button. To Fix That Try To Repeatedly Keep Pushing The Power Button Hard To Try To Unstick It. To Read More About The "Sticky" Power Button Problem Goto the 1STOP info section.

If you tried ALL of above tests and phone is not recognized by your computer you then have a hardware problem with the phones usb port. Read this for possible fix - FIX FOR PHONES USB PORT

4. WHAT IS AND WHY DO YOU NEED A CUSTOM RECOVERY

YOUR PHONE COMES STOCK WITH A PROGRAM WE CALL RECOVERY 3e.

TWRP ARE CUSTOM RECOVERIES THAT REPLACES THE STOCK RECOVERY 3e.

ON STOCK FIRMWARE YOU NEED TO USE ODIN TO INSTALL THE TAR FILE(NOT THE ZIP FILE) OF A CUSTOM RECOVERY TWRP, ITS THE FIRST AND FOREMOST THING TO DO TO YOUR SKYROCKET TO BE ABLE TO DO ANYTHING ELSE TO YOUR PHONE.

ONCE A CUSTOM RECOVERY HAS BEEN INSTALLED YOU CAN THEN BE ABLE TO INSTALL OTHER CUSTOM RECOVERIES, CUSTOM ROMS, ROOT THE PHONE AND INSTALL FLASHABLE "ZIP" FILES.

YOU DO NOT NEED TO BE ROOTED TO FLASH A CUSTOM RECOVERY

YOU DO NOT NEED TO BE ROOTED TO FLASH CUSTOM ROMS

FLASHING TWRP BY WHATEVER METHOD USED IS NOT ROOTING

INSTALLING A COMPLETE FULL STOCK FIRMWARE WILL REVERT THE CUSTOM RECOVERY BACK TO STOCK RECOVERY.

THERE IS NO OTHER WAY TO ROOT THE SKYROCKET WITH OUT TWRP

CUSTOM ROMS ARE ALREADY ROOTED: FOLLOW DEVS INSTR.

IF YOU DID HAVE ROOT AND FLASHED STOCK FIRMWARE BY WHATEVER METHOD YOU WILL LOSE ROOT.

YOUR PHONE WILL NOT LOSE APPS OR SETTINGS EITHER BY ROOTING OR FLASHING TWRP UNLESS "YOU" PERFORMED A WIPE/RESET

THE PROCRDURES OUTLINE IN THESE TWO PAGES DOES NOT TRIP THE FLASH COUNTER

DO NOT USE ROM MANAGER TO INSTALL AND/OR UPDATE CWM

5. DOWLOADS AND LINKS

MOVED TO THE 1STOP STICKY
