Hello!

I have solved this problem with adb. You can enter to your wifi g1 settings and connect the phone to the internet by wifi, and sign in your gmail account.

There are different howtodo, for example this, but I have followed another from taringa.

Bye!

advice please: new to android

First Q: If i am using Amon recovery-RA-dream-v1.5.2.img then should i rename it to recovery.img before moving it to sd-card. Should i be using the newest version of Amon recovery-RA-dream-v1.7.0?

Second Q: Do I still use the Hard SPL provided in first post OR Have THINGS PROGRESSED? If so, which Hspl should be used?

Third Q:
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.

First, choose a modified image from the list below:

ADP1.1: (md5: bacc58302e0b239d66c7bcc8db6c434b)

http://andblogs.net/2009/02/new-rc33-based-images-from-jesusfreke/

RC8: (md5: de2d0d34adbb4015ee3aa5e4e7ca3c07)

http://andblogs.net/2009/01/jesusfrekes-14-images-are-out/


  1. Download the image.
  2. Rename it to update.zip.
  3. Copy it to your phone's SD card.
  4. Turn your phone off.
  5. Start up in recovery mode by holding Home and pressing Power.
  6. Press alt-W to wipe your device. (You need to do this, or the device may hang at the flashing Android screen)
  7. Press alt-S to apply the update.

And that's it! Remember to check the links up top to learn how to use root to do the advanced things I mentioned.

First, choose a modified image from the list below: How do i do that? I am guessing RC8 but I see on this thread that JFv1.43 for UK RC9 is also available.
Which one should i use for UK Tmobile G1. Pointing towards the download link would be much appreciated :D

Also: In this last step I am confused :confused: wether I am supposed to use the 'downloads' or 'build enviornments'.

I would also like to say that I want to flash the updated image/rom which does not require the initial registration process as my sim card does not have data enabled.
I was able to bypass this at the initiall step by using adb but this doesn't work builds higher than rc7.

after third command line, it says cannot find recovery.img. any suggestions?

---------- Post added at 01:18 PM ---------- Previous post was at 01:14 PM ----------

I had root already but it got stuck on the g1 screen . I tried everything I could think of, and then decided to the the dreaming.nbh and now I have it down to the 1.0 version, and after putting the two files on my card and going to telnet, the first two commands do fine, then after the third command it says it cannot find the recovery imager(or it cannot open the recovery image.) this sucks. any suggestions?

Why should you root your Dream/G1?

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:
RC30.png


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)
  1. 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.
  2. Download and unzip the RC29 or RC7 image file. Copy the DREAIMG.nbh file to the SD card. (RC29 for US, RC7 is for UK)
  3. Turn the device power off.
  4. Hold Camera button, and press Power button to entry boot loader 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.
  5. As per the on-screen instructions, press the Power button to start upgrade procedure. DO NOT DO ANYTHING TO INTERRUPT THIS PROCESS.
  6. 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:

Instructions:
  1. Download recovery.img or the new version by Amon recovery-RA-dream-v1.5.2.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).
  2. Download the Hard SPL and copy the zip file to the SD card.
  3. All files must be on the root of your SD card.
  4. Restart your phone. Wait for your phone to start up fully and show the home screen.
  5. 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.)
  6. Download an Android "Telnet" application from the Market and connect to localhost.
  7. If you connect successfully, you will have a root prompt "#".
  8. 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
    • cd sdcard
    • 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.

  1. Power off your phone.
  2. Start up in recovery mode by holding home and pressing power.
  3. You will now enter recovery mode. You should see an exclamation.
  4. If you do not see a menu on screen, press Alt-L to show the menu.
  5. Press Alt-S to apply the update from the SD card.
  6. 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.

First, choose a modified image from the list below:

downgrade is obsolete.
just to root you may want to use SuperOneClick for example. the above cyanogen tutorial is also a very good start ( not only for rooting ).
