Manual to get root in cell G1 with Android (1.6 or 2.0)


From version 1.6 1click root system does not work if your Smartphone is in any previous version skip to item 3.2 below.

I updated my phone to version 1.6 for there to decide that I wanted a little more of it, and from this version is a bit more complicated to obtain root privileges and can install the modified versions of Android eg CyanogenMod .

To follow this manual recommend having at least a basic knowledge of Linux alias without it I would not advise putting the phone in Root, it will be much easier to damage the unit. I am not responsible for the following, I followed the manuals that will show and for me it worked but I could have lost the device if something went wrong.

But what are the advantages of this process:

  1. limiting the official version only allow you to install programs on internal memory in my case was 60MB, with the latest versions of programs CyanogenMod go directly to the SD since it has an ext2 or ext3.
  2. The possibility of using a partition-partition Linux SWAP
  3. Be able to provide the Internet appliance (tethering) to your computer or laptop via USB Wifi
  4. And much more see the list at http://forum.xda-developers.com/showthread.php?t=567610

Of course there are disadvantages for example the automatic update is off but for that we already own Cyanogen an application that makes the upgrade from them.

1-DOWNGRADE

So let's start first of all you must do a downgrade to version 1.0, or we will return the phone to its original form before the updates, this procedure will also be necessary if we are to withdraw privileges Root and again have access to the automatic updates direct from Google.

Here I had two paths or two books a lot like an easier and one that worked . The easiest basically do not need Goldcard. I advise trying first to make this straightforward procedure if the author could perhaps work with you and save you some steps, the manual Cyanogem own says nothing of Goldcard.

In both cases we must first file DREAIMG.nbg RC29 (U.S.) [Link1] [Link2] if you have an appliance or American RC7 (UK) [Link1] [Link2] if you have a European device, unzip the file and put DREAIMG.nbh the file to your microsd card from your G1. Do not rename the file, the file name has to be DREAIMG.nbh

The procedure without Goldcard just switched off the device, press and hold the button to take photo and power button.

Bootloader It will connect in recovery mode, in my case I received the error 00028002 (not allow) and returned to the screen of the rainbow. I have checked the message and found that it meant that my CID was wrong, this error also happened to me once with the Goldcard but I think I must have done some mistake in time to copy the number of CID, for the second time worked. In the comments of the manual also has a user who received an error message but simply formatting the SD, and placing the file DREAIMG.nbh worked, is one possibility.

To exit this screen you can dial by pressing the Menu + + End, in my case I was forced to remove the battery and USB cable as this combination was not working.

Downgraden_2 Downgraden_1 If you run these two screens will appear next, the first asking to push the power button to start the process. Care for your cell phone battery does not run out this procedure because it can be to defeat the device. If managed istalar will not be necessary to mount the Goldcard, and the device will be in version 1.0.

2-GOLDCARD

If you did not install DREAIMG.nbh is necessary to mount the Goldcard, first install the application Astro File Manager and then go with him to the folder / sys/class/mmc_host/mmc1/mmc1: / XXXX where XXXX is a hexadecimal number, ICD-click the file and open it as text, vai aparecer um número, na verdade são uma sequencia de números com dois algarismos por exemplo:
vai aparecer um número, na verdade são uma sequencia de números com dois algarismos por exemplo:

035344535530314780601c619e00822e
03 53 44 53 55 30 31 47 80 60 1c 61 9e 00 82 2e

It is necessary to reverse this sequence and then remove the spaces:

2e 82 00 9e 61 1c 60 80 47 31 30 55 53 44 53 03
2e82009e611c60804731305553445303

Place this code in the form below, or on site http://revskills.de/pages/goldcard.html that you receive via email the file goldcard.img

Email:
Confirm Email:
ICD code (already inverted):

Now format the SD card (Backup if required) I preferred to copy the image (goldcard.img) with the dd command from Linux, but you can do in Windows with the hex editor HxD Hex Editor, see the manual:
http://forum.xda-developers.com/showpost.php?p=4289899&postcount=1

Following with Linux, connect the device via USB, it should automatically mount with the command "mount" where we discover that this unit:

/dev/sdb1 on /media/disk type vfat ↩
(rw,nosuid,nodev,uhelper=hal,shortname=mixed,uid=1000, ↩
utf8,umask=077,flush)

In this case at / dev / sdb and the first partition is in / dev/sdb1 with the command "sudo umount / dev / sdh" disassemble this unit, with the command "sudo fdisk / dev / sdh" and then "p" check in this case it appears fat32 "/ dev/sdh1 1984 991 747 + 6 FAT16" in this case press the "t" for partition type and then the "b" at the end will have this "/ 1984 991 747 dev/sdh1 + b W95 FAT32 "by pressing the" p "(print), press" w "to save and Ctrl + C to exit.

Then format the partition "sudo mkfs.vfat-F-32 s 8 / dev/sdb1" and being in the directory where the file goldcard.img apply it to the SD card with the command "sudo dd if = of = goldcard.img / dev / sdb "care that is not for the partition sdb1 and yes to the root of sd card.

Now copy the file back to the SD DREAIMG.nbh unplug the unit and repeat the above procedure again going into recovery mode. (Picture taking button and power button)

3-ROOT

Now we again have two paths we can install version 1.5 and get the Root with the application or take FlashRec we're on version 1.0 and get the Root via Telnet.

3.1-TELNET

Copy to SD card file cm-recovery-1.4.img [Link1] [Link2] to the root of the card (no directory).

Remove the USB cable and the WiFi connected press the Enter key twice and then "telnetd" (no quotes) and enter again

Now enter the settings of your modem to see the IP of the device after the command " telnet" eo IP do aparelho(Tanto no Linux quanto numa janela do DOS), no meu caso foi "telnet 192.168.178.24", se ficar só o simbolo # é que você esta conectado.

Enter the commands:

# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# cd sdcard
# flash_image recovery cm-recovery-1.4.img
# cat cm-recovery-1.4.img > /system/recovery.img

Congratulations you now that the unit under Root.

3.2-FLASHREC

Another way to get root privileges is putting the official version 1.5 Cupcake [Link] , rename the file to restart your update.zip G1 pressing power + box and install it.
Now your G1 is in the cupcake version 1.5 but without root access.

Download the application flashrec.apk [Link] , open the application. Once open you will see two buttons, click the "Backup Image Recovery." Expect him to conclude the process and click "Cyanogen Flash Recovery 1.4", wait a little longer.

Give a reboot in recovery mode on your G1 + Power house and now you can install the room you want.

4-HardSPL (Alternative Bootloader)

If you are wanting to install only the versions of CyanogenMod not nescessário this procedure, but if you want to install any version, for example JesusFreke nescessário-ROM is one more step.

Copy the file update.zip [Link1] [Link2] to the root of SD, unplug the appliance, a relic of the House with the button (Home) + Power, select [Alt + S] apply SDcard: update.zip and ready Home + press return to restart.

5-Flash & CyanogenMod 4.2.3/4.1.9999 Android 1.6

    I would like to make any changes before an original backup of my phone is htc g1 Tmobile with the 1.6 firmware would love to put htc superhero g3, but it goes in the middle of the year HTC chose to release the update for htc g1 android 2 that liked most of these changes are support for flash that I learned that soon everyone will have flash support and one thing I liked in htc superhero is the system of music album. what do you recommend? to wait a little longer or make changes as htc rom for a superhero.

    Not tested yet the ROM of Hero. studies and also hoping to leave the 2.0 version superior to the G1.
    Once released the Root options by turning the equipment holding the home increases, among them is released Nandroid that makes up the whole system. But to get the Root have to go back to version 1.0
    If you later want to return the unit to its original form and without access Root have to do the first part of the Handbook back to version 1.0 and then upgrade straight through the settings menu with the updates.
    The ROM I'm currently using is that of Cyanogen with Thema BlackIce, the theme adds many cool things like folders in the main menu, because with the applications installed on SD just exaggerating the amount of stuff installed, and so it was easy to organize everything .

    First you with this Cyanogem ROM and installed with root access right?
    If you are doing the update via EDGE or WiFi switch to 3G, operators have to limit the download 5 MB.
    Try to uninstall the program and reinstall it, and once with the care Cyanogen running is no longer possible to remove the SD if you have a second partition to the APP. For he can not dismount more SD.
    Today I took the SD without disassembling reintalar and now I have several applications that are in error.
    What part is giving this error in the download or installation?

    Do not know anyone in Brazil, but a look at the forums.

    Alias the current version of Cyanogem is 6 which is based on the new Android 2.2. In G1 there's no way if you want to have a newer system has to crack because there saira updates. Care but to lose the unit, check whether the model is the same manual that you follow and is preferably not install packet radio

    Search the forum http://forum.portalandroid.org staff it is very good

    Hi Do you know any place where I can take my G1 to do this upgrade process. I'm not very familiar with Android and even Linux. I'm afraid to damage the unit.

    grateful
