Preparing to take the plunge and root - not clear on a couple steps.

---

This much is what I have clear...

·Format my SD card for FAT32
·Flash down to RC29
·Download recovery.img
·Download hard SPL
·Copy both to the root of my SD card
·Restart, go through the telnet process to gain Root
·Apply the Hard SPL

I already know what build I want - JFv1.51 ADP

However, I've been unable to find instructions on how to install it once I've gained root. I keep hearing some stuff about the radio and whatnot and I'm a little lost. :3

Blarg. Had a nice reply typed up almost ready to submit, and we had a power outage at work. Guess I get to type it up again.

After you gain root access, you need to download the radio update from here and the JF 1.51 update from here (assuming you don't have it already).

Copy the radio zip to your SD card and rename it to update.zip. Turn the phone off and boot it into recovery mode (Home + Power). Apply the radio update with Alt+S. Reboot the phone with Home + Back when prompted.

After it boots back up, move/delete/rename the radio zip and copy the JF 1.51 update to the SD card and rename that to update.zip. Reboot the phone into recovery mode again. Press Alt + W to wipe data (can't remember if this is needed or not for going from RC29 to JF 1.51), and then press Alt + S to apply the update. Reboot again when prompted, let it boot up and you should be good to go.

If you decide to go to other builds, the process will be the same.

I have a question along these lines. I did all of this and it updated fine, but I lost root. Was there a step I left out or something that I needed to do after?

So long as you followed everything in the rooting guide here on XDA to the letter, you should have root. Applying the radio and build image should not remove root access.


To verify if you do, open up the terminal emulator and type su. If it comes back with a # prompt, you have root (Superuser Whitelist may come up asking if you want to allow the action, tell it to allow the action).

And it's safe to flash the radio after the spl?
