installing root, flash_image permission denied - Droid Eris Q&A, Help & Troubleshooting

going through the entire 1.5 to 2.1 root tutorial to a tee, but once i get to the recovery image, this happens (following is an entire copy/paste of what I went through, incase i did something wrong before i hit the point)

C:\Users\Lemcott>cd C:\android-sdk-windows\tools
C:\android-sdk-windows\tools>adb shell mount -o rw,remount /dev/block/mtdblock3

C:\android-sdk-windows\tools>adb shell flash_image recovery /sdcard/recovery.img
flash_image: permission denied

EDIT: I am a complete ass hat. nothing to see here, move a long. mods delete this if you please.
P.S. Everyone else: ALWAYS DOUBLE CHECK BEFORE POSTING FOR HELP. *ahem* now be on your way.

It looks like you forgot the step where you modify the flash_image's permissions
Code:
adb shell chmod 755 /system/bin/flash_image

---

I had the same thing but I just kept reentering
adb shell mount -o rw,remount /dev/block/mtdblock3 /system
adb push recovery.img /sdcard
adb push flash_image /system/bin
and after maybe 4 iterations it worked.

I have a very simular problem:
(moto droid with android 2.1)
$su
su
Permission denied
Click to expand...
Click to collapse
I have try to use chmod the file but it said permission denied on chmod... please help T_T
note this is rooted, of course, when i'm in the phone type su, it'll pop up ask for me to allow or not, allowed, everything seems fine, but when i try to modify files in /system/etc/wifi (trying to make it work for ad hoc) it said permission denied....(even in su???) I tried in adb and it's the same, very very frustrating, any help is appreciated, Thanks.
edit: here's what it looks like using chmod...
>adb shell chmod 755 /system
unable to chmod /system: Read-only file system

I wouldn't try to flash anything you find here to a Moto Droid.
This is for the HTC Droid Eris.
Otherwise, and if I'm misunderstanding you, good luck with your problem.

I know that the flash_image fil and my recovery.img file is in this library and also on my sdcard, but I cant push the gotdamn flas_image file in the /system/bin catalog.
Can some one please help me ?

How do you know that you have root? Or, how did you gain root?

I'm not aware of that app, and cannot find it in the market myself (do you have a link?)
However, one way to check for sure if you truly have root is run the adb command adb shell and, when you get a prompt, type the command "su". If it returns with a "#" prompt (rather than the "$" prompt that you are seeing), then you have root on the phone.
Most people these days root with either jcase's 1click root for eris: https://market.android.com/details?id=net.andirc.erisrooter or they use the procedure here: http://androidforums.com/eris-all-things-root/127861-universal-eris-root-dummies.html
You may be able to use the steps here as well, since you seem pretty comfortable with adb and have that working already: http://androidforums.com/eris-all-things-root/125436-detailed-leak-root-tutorial.html

Guys new I found another solution (tested on u8150)
First make sure that you are rooted first.
Open adb shell
Type in su.
Remount the system partition as read write.
Change the owner of system from root to system via chown root system
the exit the shell and push flash_image to system/
also push clockworkmodrecover.img into the system partion dont forget the last /.
then exit.
use a file manager, I used rootbrowser.apk without a memory card and installed recovery.
with rootbrowser copy flash_image to the bin directory.
don't forget to change the owner back to root to the system partition after you finish with rootexplorer or whatever u use even adb can work.
then the rest follows.
The above works only if your'e rooted and have adb.
Goodluck

haha am a genius Installing ROM +Recover without sdcard on u8150
all you have to do is:-
1. Make sure u have installed clockwork mode recovery on your device and have su binary.
2. Open adb with the device normally on.
3. Remount the data partition as read write using mount remount in adb .
4. use adb and push the cynogenmode.zip or any rom that fits into the data partition using
adb push romname.zip /data/
5. Reboot into clockworkmod recovery using the various options available.
6. This is what to do if you don't have a sdcard.
open adb with phone connected and run
adb shell
mount /data /sdcard
then go back to the main recovery menu and wipe dalvik cache only
then choose update from sdcard
flash your rom and tadaaa.
your'e done.
NB:CAUTION MAKE SURE TO FLASH A ROM THAT DOES NOT WRITE INTO THE DATA PARTION
THIS CAN BE DONE BY LOOKING FOR A FILE CALL UPDATE SCRIPT IN THE zip OF THE ROM U WANT TO INSTALL
Am going to make a post about this later.
Goodluck

Lol, 3 and a half year break between responses.

The problem with flash_image & dump_image is that it doesn't work on devices devices which use emmc (recent phones)and have
mmcblk0
and cat /proc/mtd won't work here either.
This means that you have to use dd to write to this devices.
I wonder how guys determine the partitions to use on such devices, and someone should hint as to what is going on since it seems manufacturers seriously don't want people to exploit their devices.
