I have been trying to root my phone. I ended up downgrading my phone back to 2.1, but when I try to flash a rom using the update.zip I end up getting the following errors:
E:Can't open /cache/recovery/command (this comes up before even trying to run the update)

--Install From sdcard...
Finding update package...
Opening update package...
Verifying update package...
E:signature verification failed
Installation aborted.

I don't have root access. I haven't really found a method that I could understand fully. I want to flash a much better rom on this device. Any help would be greatly appreciated.

I too am having problems rooting. Here is an output from adb of what is going on with me. I imagine it is something pretty simple.

Code:
$ cd /data/local
$ chmod 04755 *
$ /data/local/flash_image misc /data/local/mtd0.img
[1]   Illegal instruction     /data/local/flash_image misc /data/local/mtd0.img
$ chmod 04755 * /data/local/flash_image misc /data/local/mtd0.img
Unable to chmod misc: No such file or directory
$
Thanks!

Thanks!

I am having the same problem with the above error:
cd /data/local
$ chmod 04755 *
$ /data/local/flash_image misc /data/local/mtd0.img
[1] Illegal instruction /data/local/flash_image misc /data/local/mtd0.img

I am definitely a noob and could use a little help to get this old phone rooted so I can flash CyanogenMod 7.2.

Thanks,
Dan

Same issue here when running flash_image.

Prior to attempting to run it, though, I can't get the "rageagainstthecage-arm5.bin" to work correctly. When I run it, debug mode never comes back until I reboot the device. So, I tried using superoneclick to root it, assuming that grants enough permission to run flash_image, so I'm not sure if this issue is related or not. (FYI: I'm using the cyanogenmod instructions, which I assume you're trying to do too). (Superonecliek DOES give me a root prompt [#])

Anybody have any ideas?

I have tried googling that, and almost every possible combination of "espresso, android, s-off, root, flash_image, misc, etc.".

I have tried at lease 4 different root methods:
One gets stuck at "adb push exploid /sqlite_stmt_journals" erroring: "failed to copy 'exploid' to '/sqlite_stmt_journals': Read-only file system"
One gets stuck at the place i described in my prior post.
Others fail otherwise.

One thing I haven't tried is factory resetting the phone (clear user data) before trying.

I've spent hours and hours researching and trying things for this. Just keep getting stuck.

I'll see how it goes from scratch tonight (forgot to bring my microSD card with me today).

For some reason, factory resetting was the key.

Thanks for the suggestion to google, though.

Post problem with rooting
pls i nid help urgently.
i hav been on attemps to rooot my t-mobile mytouch 3g slide for more than four weeks but have been unable to get at anything untill i stumbled over the superoneclick method which helped me to effect root, but i got stocked at the point on of flashing clockmod recovery. instead of displaying the downgrading bar at the uper right angle in recovery mod after holding down volumedown and pressing power, it takes me to the this "image not found....." and the
fastboot
recovery
.bootlaoder
........
if i select recovery, it will tell me
E: cant open .......catche......bla bla bla,

it will display the options to r
reboot system
,....update.zip from sdcard,
wipe catche/factory reset
wipe catche/sdcard partition

(this is just an idea of what is displays not exactly word-for-word).
if i select install update.zip from sdcard it ends up telling me several junks and that update.zip file verification failed.

PLEASE WHAT DO I DO GUYS.ALMOST FED UP PLSSSSSSSSSSSSSSS
