Follow the instructions to go back to RC7 until you have (permanent) root and then go to 1.5 (pref. with a wipe). Don't forget to upgrade the radio to the one that comes along with 1.5 (see jf's blog also).
So, I have a Dev Phone1, and stupidly let it apply an OTA update to 1.5. It appears that this (of course) didn't use the rooted version, so here I sit with a Dev phone that's not rooted on version 1.5. My question is does this procedure work with 1.5? My thoughts are to use this to downgrade it to a rooted version of RC33, then get JF's 1.5 build.
Sound about right?
seems right .. i don't remember if there's anything special to do with Dev Phones but it should work when you flash back to the earlier image
well like most ppl i watched plenty of videos and read a lot of how to articles but i found a video on youtube of a guy explaining every step of the process... and i know a lot of ppl are still confused on how to do the rooting and getting cupcake... i am running off of the model number android dev phone 1.. firmware version 1.5.. and i can tether my phone to where it is a wireless router for my laptop... very cool... i am now just trying to find whatelse i can do besides new widgets and storing to sd card... i would like to run apps from the sd card... havent figured that part out yet... but anywho .. here are the links of the exact steps i followed to root my phone...
Well, hopefully one of those reasons convinced you to get root access on your phone!
Preparing to Get Root on your Phone
Getting root on your phone involves exploiting a security hole that existed in an early version of Android. The versions with the security holes are known as RC19, RC28, and RC29 (or RC7 or lower for UK phones). As of RC30 (RC8 on UK), Google patched the security hole so that your phone can not be rooted (don't worry, we can still root it!).
To check your version, go to the Home Screen, click your menu button, choose "Settings", and then click "About phone". You will then see the following screen:
If you have US-RC30/UK-RC8 or higher, you will first need to downgrade your phone to a previous version. (Skip these steps otherwise)
Format your phone's SD card to FAT32 mode:
Hook your phone up to your computer using a USB cable and then wait for the notification to show up in your title bar of your phone.
Click the notification, and then click "Mount".
A new removable disk should show up on your computer. Right click it and select Format, and select FAT32 as the file system type.
Download and unzip the RC29 or RC7 image file. Copy the DREAMIMG.nbh file to the SD card. (RC29 for US, RC7 is for UK)
Turn the device power off.
Hold Camera button, and press Power button to entry bootloader mode. You should see a gray/white screen with instructions to flash your phone with the update on your SD card. If you don't see that, make sure you followed the instructions properly.
As per the on-screen instructions, press the Power button to start upgrade procedure. DO NOT DO ANYTHING TO INTERRUPT THIS PROCESS.
After it is finished, perform the restart your phone.
Rooting your RC29 or lower phone:
On RC29 phones and lower, anything you type into your keyboard is also being run in a hidden console with root permissions. More information regarding that at the bottom of this post. But, to get root access, do the following:
Download recovery.img and copy it to your SD card (see the previous instructions on how to copy from your computer to your Phone's SD card).
Download the Hard SPL and copy the zip file to the SD card.
All files must be on the root of your SD card.
Restart your phone. Wait for your phone to start up fully and show the home screen.
After your phone starts up, hit the enter key twice, type "telnetd" and press enter. (Yes, it will start up a contact search, don't worry. Just type it.)
Download an Android "Telnet" application from the Market and connect to localhost.
If you connect successfully, you will have a root prompt "#".
Type the following into Telnet (these commands will give you root access easier in the future):
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
flash_image recovery recovery.img
cat recovery.img > /system/recovery.img
Now you have root!
What To Do Now That You Have Root
Now that you have root, you will want to apply "Hard SPL" to your phone. HardSPL is what will allow you to apply flash images from other regions (like UK on US phones, and vice versa), create full backups of your phone, install the latest build from the Android source, and usually resurrect your phone if it is "bricked". You have already downloaded the file to your SD card, so now you can apply it.
Power off your phone.
Start up in recovery mode by holding home and pressing power.
You will now enter recovery mode. You should see an exclamation.
If you do not see a menu on screen, press Alt-L to show the menu.
Press Alt-S to apply the update from the SD card.
After the update is complete, hold Home and press Back to restart.
And now, the last step! You are still running an old version of Android, but you want to upgrade to the latest and greatest update! You can do this, and not lose root by downloading modified versions of the updates.
