Root EPE54B to froyo

if you have the unloced pad lock in opening screen. when you tried to load did you wipe before? i had issues because i didn't wipe.

talk to DaffyDuck he is a pro at this.

 

coming off of cyan 506, and lots of people have said 507t2 as well, you dont need to wipe. i didn't, running fine.

and yea, my benchmark is about 5x faster now on a stock kernel.

 

FRF50 (Froyo) pre-rooted update zip - Android @ MoDaCo

I followed the steps there and it worked perfectly (yay froyo!). I would recommend getting ROM manager from the market first, flashing the clockworkmod recovery, and using nandroid to backup everything first, just in case.

 

I went from EPE54B to running android 2.2 (FRF50). My phone had previously been unlocked and rooted running Cyanogen 5.0.6 then back to stock again as I assumed I would get the update OTA. If you want to know how to unlock and root your phone go here:

[Guide] The 100% Fool Proof Guide: STOCK N1 to ROOT to SENSE UI/CM! - xda-developers

Make sure that you read through everything very carefully as unlocking the bootloader voids your warranty and if something goes wrong while installing an image it can brick your phone.

If your still feeling brave here are some links for the rooted 2.2 rom:

can anyone recommend any tutuorials on how to use rom manager and titanium backup.

 

I can just try and tell you. I'm assuming you are using these to backup your data for a Froyo upgrade. Hopefully this will all make sense...

First, for both of these apps you need to be rooted. Make sure you have done that first. I recommend this: 10/May ERD79 -> EPF21B - Superboot - rooting the Nexus One - Android @ MoDaCo
Make sure you select the correct build for your phone.
After you root, you can get the froyo update file from the following link and put it on your sd card: FRF50 (Froyo) pre-rooted update zip - Android @ MoDaCo

For Titanium Backup (which is a great program, but not needed if you are about to do a nandroid backup, but I'll post this just in case you want to use it anyway)
1. Download Titanium Backup from the market.
2. Start the program and allow it to access superuser permissions.
3. click on the menu button, and click the "batch" options.
4. The third option down should be "backup all user apps + system data." Select this option by hitting the "run" button right next to it.
5. Hit the "select all" button, then hit "run the batch operation." (I would have the "kill selected apps" option over the don't kill, but its really up to you I suppose. I'm not sure, but I think that if they aren't killed, it can't make a backup.)
6. And your done creating a backup.

For ROM Manager:
1. download ROM manager from the market
2. start it up, and select the first option-"Flash ClockworkMod Recovery" (It should ask you if you want to allow the application to have superuser permissions, click allow so it will work")
3. First, make sure you have about 300 mb on your SD card for the backup files (at least thats how much room mine took, the more is probably better). Turn off phone.
4. Hold down the trackball and power the phone on. This will cause the phone to start in fastboot, which is a white screen with skateboarding androids on the bottom.
5. Press the power button to start up Bootloader.
6. At the next screen after a few seconds, your phone will check the files on your SD card. When the selection menu comes up again, press the volume down button once to highlight "RECOVERY" and hit the power button to select it.
7. The new recovery you flashed in step 2 should now show after a few seconds, showing you several options. Select the option that says "nandroid", then select the option that says "backup."
8. When your phone is done creating a backup, You are free to install the upgrade. Do this by selecting "install zip from sdcard" in that recovery menu, then select "choose zip from sdcard"
9. Select the upgrade file that you put on your sdcard earlier.
10. Let the phone run its course for a while, and you will get a confirmation message saying that the installation completed successfully.
11. Assuming nothing has gone wrong, select "reboot now" from the recovery menu. (if something goes wrong and you cant boot into your phone, you can restore your phone to its pre-update form by booting into fastboot, going into bootloader then recovery again, and going into the nandroid menu and selecting "restore." Just select the restore file that you want to apply.)
12. Congratulations, you have FroYo!

Let me know if you have any problems and I will try and help out. But honestly, I followed these steps exactly and had no problems, so I'm not really certain I'll be able to troubleshoot that well.

 

i'm alreay rooted and have froyo. i just see those apps dicussed so wanted to see how to use them. i understand the titanium backup now.

the rom recovery app, will that replace the recovery i have now? i have armon1.7 now.

 

Yup, it will replace the custom recovery. Although I think there is another option down the list of ROM Manager that installs that recovery instead. I just listed ClockworkMod recovery because that is the one that I used and had success with it.

 

Turn on usb debugging.

 

You need to be in fastboot

 

Er, you have unlocked your bootloader already, right?

 

Just checking lol

What's the output of the batch file?

From the command prompt type fastboot-windows devices and this will tell you if the fastboot program recognises your phone.

 

Yep that's good, it knows your phone is connected (the HT9blahblah is the phones serial number).

If you run the batch file from the command prompt after is run it should have some sort of message on the screen, that's the output.

 

Well reading that, it seems to have worked?

Do you have a superuser app installed now?

 

what you can do to check (from the command prompt again) is:

adb shell su

If it says 'permission denied' you don't have root.

 

I dont use titanium but now that I think of it this comes up every so often that it will claim someone needs root when they clearly have it. In that scenario you need to go into options in titanium and click one of them that tells it to check for permissions or something or other. I cant remember because it was something that didnt pertain to me. You should also have an su permission icon in the app drawer if superuser installed correctly so you can check that without even hooking up. At any rate if you find you have root go through the options of titanium and you should find a smoking gun there.
