I rooted my hero last night and tried out a few different ROMs but eventually decided to revert to stock and make some manual changes. I used nandroid to restore to just after the root (1.56.651.2). I was able to remove some apps using adb, but the adb remount command fails (permission denied), and I'm unable to push a new bootscreen on to the phone. I also tried a Root File Manager and pre-kitchen as alternatives for the bootscreen, and neither one works. The Root Manager won't paste the files from SD into /system/media/ and pre-kitchen just reboots the phone.
Any suggestions?
Any chance this has something to do with downloading only up to SDK Platform 1.5? I'm at a total loss. I RUU'd my phone, did a clean root at startup using adb shell, and I still have the same problem. The adb remount command won't work, and I can't push anything into the system directory. For what it's worth, when I still had Root Manager installed I was able to toggle RO R/W in any directory with no problem, and I could move files around within the ROM... but I couldn't move anything into it from the SD. I'm new at this, so I have no idea what the problem might be. Anyone else had this problem or have any suggestions?
If anyone else runs into this problem, this solution worked for me:
adb shell
# su
# mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
# chmod 777 /system (Or any subdirectory you want to push to inside system)
# exit
adb push <local file> <device location>
Restore modified permissions when done.
Though I'm still not sure why this is necessary in place of adb remount.
I'm pretty sure the adb remount command will not work on the stock rom. You should be able to do it with just this command instead:
mount -o remount,rw -t yaffs2 /dev/block/mtdblock3 /system

Thanks... didn't realize stock wouldn't accept adb remount. If I use the above line from within shell, that doesn't help me push anything on to the phone though... so I needed to enable global permission and then do the push. Oddly enough I tried the same approach last night using Root Manager, and the transfer from SD still failed, even after I applied 777 to the dir I was trying to modify. The current solution may be kind of tedious, but at least it works.
you really shouldn't do 777 on your filesystem, ANY app can then write to your system, overwrite things, or install malicious code. Just remount manually and you should be able to push anything you want, just remember that w/ the stock rom you also don't get a full busybox either.
I'm not positive, but I would think after you remount, you should be able to "adb push" to /system. I suppose it might be specific to that shell, but I would think not.
You just may have to do it once each time you boot your phone.
Edit - err nevermind... you're having permission errors.... um... change adbd on the phone to run as root? not sure how off the top of my head...
I can't mount r/w through root explorer.. I also tried mounting in recovery but it wont stick when the phone boots up.. anyone know how to do it?
assuming you have root, open a terminal and type the following
su
busybox mount -o remount /system
i am rooted, and i tried it.. still a no go on the r/w.. its not that big of a deal at this point i guess, just seeing if anyone knew what the deal was
my busybox won't update either.. saying i may not have nandroid backup or it was unable to remount..
my bad sorry. the second command should be
busybox mount -o remount,rw /system
awesome.. worked
Hi everyone,
A few days ago I got the OTA 2.2.1 on my MT3G and then rooted it using the SuperOneClick tool. I was able to remove all useless apps, pushed others to /system/app with Root Explorer, etc., there is only one to do, and I am clueless: how to replace the stock Android System Recovery <3e> with a custom recovery image, so I can do Nandroid backups, flash .zip files, etc?
I used the ROM Manager app to flash Clockwork, got an "Installation successful" confirmation, but then on reboot into recovery mode my phone got stuck on the MT3G logo. I had to remove the battery, then in second attempt the phone booted into the <3e> image. Restarted again, opened the ROM Manager, according to it Clockwork was installed. Total craziness! Then I tried to flash it using Better Terminal Emulator (su, flash_image recovery /sdcard/Clockwork.img) but I got a "flash_image: not found" message, though I had the image on my sd card.
Any good ideas, folks?
All useful suggestions much appreciated, thanks!
They've been excluding flash_image from htc roms lately. What your gonna have to do is put flash image on your sdcard with the recovery.img. Then mount your sdcard and run the flash_image from your sdcard and flash the recovery image. After your done then you remove the installrecovery.sh from system/etc. That is what keeps installing the factory recovery when you reboot. I get home and onto a decent internet connection in a few hours and I'll upload some adb commands to help you do this.
make sure you have the recovery.img and flash_image on your sdcard
run these commands in adb
Code:
adb shell
su
mount -o remount,rw -t yaffs2 /dev/mtdblock3 /system
rm /system/etc/install-recovery.sh
cd sdcard
mount -o remount,exec /dev/block//vold/179:1 /sdcard
./flash_image recovery /sdcard/recovery.img
exit
exit
It's kinda relative to the topic. I'm stuck on clockworkmod and would like to get back to stock recovery as the new HBOOT doesn't let me flash roms. Is there any way I can do so?
Look in my guide... all the files, steps and binaries are included...
Check out my signature!
Thanks, Asadullah. One more question: Are there different versions of flash_image for different android versions, because I saw in another forum a user complaining he/she didn't use the right binary.
Edit: I've extracted a flash_image binary from CM 6, hope it will work
Edit2: It worked, thanks a lot, man!
I think that flash_image from different devices is different someone correct me if I'm wrong. Glad it worked

I forgot to ask you one more question, don't want to open a new thread for this one, perhaps you can help again
I put the code you gave me through the terminal, since adb denied me of su permission. I installed the SDK, and after typing "adb devices" in cmd it saw the phone. "Adb shell" worked (saw the dollar sign), but then intead of getting the pound sign, su gave me "permission denied". But I get the permission when using the terminal. I also cannot see the phone directories when I open DroidExplorer, but otherwise it sees the phone and I get su permission when I use its command prompt. I thought there may be a problem with the root, but if there was, then how was I able to delete and push system apps and install the custom recovery? What do you think may cause the problem? Thanks.

I know it's been a while and you didn't get a reply, and while I found this thread because I too am having enormous trouble rooting this whatever it is cheap chinese android 2.2.1 momo 2 thing covered completely in chinese language apps that I simply cannot use even for the low price it cost me - I thought I'd offer an answer, most likely wrong, but one that may help the next person who may fall into your position.
adb root is an option to start the adb service in root mode, and I can only assume that means for the device.
As I have not been able to get this thing sorted, not knowing what it is really - no phone, no camera, no buttons on the case apart from power/sleep - Home/Esc which do nothing on booting apart from alert the PC to detect a new USB device, no market access, but otherwise exactly what I required - I dont know if it'll help.
But I hate threads left in a question, because I always find them. And this circle of frustration seriously should not be real, it just cannot be this damn hard to do something...
yikes!
help please

sir is this CM.12 cyanogenmod fakelollipop is an example of flash_image even its in a zip file? because i cant get it at all, im stuck at flash_image not found
I perma rooted my G2 using using the rage method a few months ago and when I was done I was able to delete some of the bloatware. Today I decided I would like to delete the remaining bloatware but have been unsuccessful.
I installed the latest Android SDK, enabled USB debugging, ran adb shell, and then su. I exited adb shell and then ran adb remount which results in the error "remount failed: Operation not permitted".
Any ideas on what I can do? Did I somehow lose my perma root?
Edit: My bootloader looks exactly like the image depicted in this post: http://forum.xda-developers.com/showthread.php?t=833965
Solution: mount -o rw,remount -t ext3 /dev/block/mmcblk0p25 /system
In recovery mode I am not able install any ROMS, theres the error Failed to mount /efs (Invalide argument)
I can only flash stock roms using odin, everything works on stock roms except for the wifi, after connecting/disconnecting multiple times, the wifi stops responding and wont work in the future
---------------------------------------------------------------------------------------------------------------------------------------------
(( SOLVED ))
First thing you should do, is to backup your EFS if you still have it.
I had mine but it wasn't mounting properly.
In order to back it up, please download terminal emulator on a rooted device and follow this video
I would try to back it up, even if you think the efs is messed up... worst case scenario is you end up where you started, not worse off.
---------------------------------------------------------------------------------------------------------------------------------------------
Your device needs to be rooted.
1.) Download SDK tools here - Scroll down to the bottom and "Get just the command line tools"
2.)Install TWRP , Find your device, download the .tar and flash it using ODIN
Boot in to recovery, in TWRP you want to go to mount, make sure system, esf are checked.
3. If you installed SDK tools, go to c:\android tools\SDK tools. hold shift and right click on the area inside the folder and select run command line from here.
4.) In cmd, type
Code:
ADB devices
ADB Shell
SU
mke2fs /dev/block/mmcblk0p10
mount -w -t ext4 /dev/block/mmcblk0p10 /efs
5.) You should be good!!!
