[G1 Android Development] crouchingpossum:
please help, stuck trying to root g1 first time. spl problem perhaps?

I have a US T-Mobile G1 (black)

an ativa usb microsd card reader (that stopped working last night)

radio: 2.22.19.26 (i think)

recovery: cyanogen mod v1.4 + JF

attempted rom: cyanogen: update-cm-4.2.9.1-signed

hangs at g1 screen after I tried to flash : cm4.2.9.1 (i think I forgot to wipe the first time)

a 1g microsd card (another 4g sd card available as well)

First off I apologize if this is an inappropriate place to post a "please help" ... I am quite the noob ... I followed directions from:

http://androidandme.com/2009/08/news/how-to-root-a-t-mobile-g1-and-mytouch-3g-android-phone/

(Method B – Manually downgrade your phone to RC29 to replace the recovery image)

I followed steps more or less successfully (thru the dreamimg and the telnet part, etc then I updated radio from:

("The new radio image has been posted on HTC’s support website, Android Roms page, or Haykuro’s Sapphire Port page. In order to apply the Radio update, we must download the file “ota-radio-2_22_19_26I.zip")

Then I stopped to verify 2.22.19.26l in my settings. All seemed to be dandy. Then I tried to flash the spl

(using the following instructions:"

Download the latest SPL(1.33.2005) from Haykuro’s Sapphire-port page.

Copy the SPL file(spl-signed.zip) to your SD card.

Reboot your phone into recovery mode. (Power off phone. Press and hold Home key then press power)

Wait for Cyanogen’s recovery image to load and select “apply any zip from sd”. Flash the spl-signed.zip file.

After flashing the SPL, you must flash a custom rom or your phone will not boot."

This is where my problems began. The previous two .zips were easy to drop into the sd card bc the g1 was able to mount to my pc)

After flashing the spl I realized I needed to put the custom rom on the sd card using my sd card reader

(which stopped working somewhere in the middle of the process, so I started to freak out a lil bit ...)

This is where I get a little hazy:

My g1 kept hanging on the Tmobile g1 screen (i popped the battery and sd card out to copy the custom rom onto the card)

henceforth:

(unless I held home+end to boot into cyanogenmod v1.4 + JF recovery)

I tried to drop update-cm-4.2.9.1-signed into the sd card using my nokia phone to write to the sd card"

It continued to hang on the Tmobile g1 screen :

Then I realized I had forgotten to wipe. I've been Popping the battery and sd out every time it'd hang (is there a more appropriate force restart key combo or something to safely stop a g1 that's frozen up?)

and then restarting in recovery by pressing [home+end]

Then I performed a wipe and tried again, still hangs, then I read a post from: the link:

“Let’s fix that SPL“.

then I tried to rename my update-cm-4.2.9.1-signed to update.zip instead using recover tool to "apply any zip from sd",

then I tried Hard SPL , to sd card, rename to update.zip, restart with recovery [home + end]

now I'm hella confused and I am afraid to try to go back to the beginning to start over because my understanding is that if I try to revert to RC29 using DREAIMG.nbh I'll end up with a brick because I think inside the guts of this hanging tmobile g1 screen that this phone has a

Hard SPL so I don't want to allow DREAIMG.nbh to roll back to the old ota radio file that'll brick me.

sorry so long-winded.

Please help.

peace,
