How To Update HTC Dream G1 to Gingerbread 2.3.5 Firmware

Procedure to install Cyanogen Mod based Gingerbread 2.3.5 ROM on HTC Dream G1:

  • First up you will have to ensure that the Clock work Mod is installed in your phone which you can do it by installing the ROM Manager which you can download from the Android Market Place.
  • Now, all you need to do is to first root your phone before further proceeding to the method. The HTC Dream G1 can be rooted by following this link. Now, once you have rooted your phone you will have to proceed to download these two files which are the Cyanogen Gingerbread 2.3.5 ROM and also you will have to download the Kernel additionally followed by the Google Apps. All these files are the zips files which you need to download it from here.
  • Now, as soon as you download all of the three things which are the Gingerbread 2.3.5 ROM, Google Apps and also the Kernel, now all you need to do is to just copy all of these files to your HTC Dream G1 Phone.
  • Now, you will have to enter the phone in the recovery mode. The recovery mode can be entered by Booting the device into Recovery by holding the Home and Power button while the device boots. But before you proceed to enter into the recovery mode, you will have to turn off the device.
  • Now, from the list of the recovery mode options, you will have to select the option of “Install zip from sdcard” which you can select by scrolling down with the help of the Volume keys.
  • Now, first you will have to select the file which is nothing but the ROM which is named as the “update-cm-7.1.0-RC1-DS-signed” and then after that you will have to again come to the recovery mode and then select the option of Install zip from sdcard” and choose the kernel file which is “ezgb-2636-v1.5_S”.
  • Now, once both files are updated and are applied, you will now have to now again go to the recovery mode by holding the Home and Power button while the device boots. But before you proceed to enter into the recovery mode, you will have to turn off the device. In the recovery mode, select the option of “Install zip from sdcard” and then after that you will have to choose “gapps-gb-20110613-signed” file which is nothing but the Google Apps.
  • Now, once it’s done, just reboot the device. Now, again turn off the device and then you will have to again boot your device in the recovery mode so that you can clear the cache which can be done by selecting the options wipe data/factory reset, wipe cache and wipe dalvik cache.

That’s it you have now successfully updated your HTC Dream G1 Phone with the latest version of firmware 2.3.5 Gingerbread version. Do let us know in the comments section below if you face any issues while updating the device.

    hope you can help
    Thanks in advance

  • richard

    Ok so I’m rooted already and running CM 6.1.0 (FROYO) ON MY g1. Theoretically that means all I have to do is just boot in recovery mode, flash the ROM for the current revision – which is actually a version of 2.3.7 now – and flash the kernel then apps, correct? I’m actually using an old cyanogen recovery image via flashrec, as every time I tried to use rom manager to update my recovery image it will SAY it updated but won’t.

  • Paolo

    Hi Neal,
    thanks for the tips
    The problem is….

    I have Clockwork Mod.
    My dream is rooted
    I tried to do all you said but when try to install the zip from teh SD card it says:

    Installation aborted.

    Any solution? ;)

    • http://twitter.com/pradeepneela NeaL Pradeep

      is the phone rooted?

  • Bill Wetzel

    Your instructions specify using ClockworkMod. There is a strong statement on the CyanogenMod wiki that ClockworkMod should not be used on the Dream (G1) because of low memory issues and file corruption.

    Can I use the recommended Amon_ra instead with this build of Gingerbread?

    Thanks,
    Bill

    • http://twitter.com/pradeepneela NeaL Pradeep

      yes you can use that one too!

  • SASWAT

  • muispluis65

    Hi there,

    Last January I have bought a G1 with Mod version BiffMod-2.1 from my nephew.
    My question is if it is advisable to install this android version 2.3.5 according to the instructions on this site.
    P.S. I also understood that a part of the Biffmod installation is on the SD card, is that a problem?

    Greeting,
    Muispluis

    • http://twitter.com/pradeepneela NeaL Pradeep

      but in the biffmod installation, you need to install the CWM, have you installed it?

      • muispluis65

        Sorry to be a newb but I learn quickly. Is CWM to backup? How can I check if it’s installed?
        When I hold phone and Home buttun at the start up I get an menu with folloing options:
        -reboot systems now
        -apply sdcard:update.zip
        -apply any zip from sd
        -wipe data/factory reset
        -android 2.2 backup
        -restore latest backup
        repair ext filesystems
        -go to console

        Thanks in advance,

        Thanks,

        • http://twitter.com/pradeepneela NeaL Pradeep

          you can download titanium app for all your backup!

    Hi Androids,
    I’ve tried this method, but failed. “Install zip from sdcard”is not a option in recovery mod. I’ve renamed the rom to update.zip. Afterrunning that option an error occur. What do i wrong?
    Greeting,
    Lucas

    • http://twitter.com/pradeepneela NeaL Pradeep

    • The Eaglet

      • Pradeep Neela

        there will be an Option in the recovery mode

    • kuldeep tyagi

      actually you have not install recovery image……after rooting first install telnet and type telnetd press enter 2 time open telnet type the command “recovery_image sdcard/recovery.img” press enter and reboot with pressing home botton to recovery
