Help please! Phone wont boot. Need adb expert.

Hey all. I did something silly and deleted a file in system/bin folder while troubleshooting a problem. I made a backup of the file before deleting it in sdcard/download but my phone wont boot so I can copy the backup file back to system/bin. I am able to get my phone into download mode and I believe I could copy the file via adb. However I do not know how to get adb to recognize the phone in download mode. I type...
adb devices
and it states "List of devices attached" and there is nothing under the list but when I plug my phone via USB it shows "SAMSUNG Mobile USB CDC Composite Device" in device manager so I know my pc is recognizing it. I have used adb before with batch files like 1click root and things like that so I know its just me not knowing the right commands to get my device recognized.
Any and all help is appreciated! I just need to copy 1 file from sdcard/download to system/bin and I would assume it would boot back up with no problem!
Thanks!

do u have cwm installed?

I just installed CWM v5.5.0.4 via download mode using this method. http://www.theandroidsoul.com/skyrocket-root-clockworkmod-cwm-recovery/
So now that I am in CWM I am trying to mount things like /system and it shows an error mounting /sdcard and I get that error messaging for mounting all except mount usb storage which works great. I was however able to get the file off my phone but now how do I get the file back to system/bin?

Yes.. you can (and really should) flash CWM from download mode via your PC/laptop. A few weeks ago I did something very similar and soft-bricked my SR by renaming an in-use file (framework-res.apk)... I also only had 3e, so couldn't just restore a nandroid or flash a rom zip. Go to the Dev section and find the thread by Copperhed ("Root the ATT SGH-I727 Skyrocket..."). read through the OP and follow instruction exactly. You will be Odin3 flashing just the CWM recovery partition... this will NOT trip your flash counter. If you are already rooted, you should retain root... if not, you can root via his OP. After you have CWM recovery, there's a way you can mount the sdcard so you can transfer files between your PC and SR... then, you can put the sbin file back and see if it reboots fine... if not, with CWM installed, you can flash (via zip.. not Odin) any rom/kernel/modem zip package you want.

Even though I installed CWM from a different source I thanked you anyways DoctorQMM! Now that I have CWM installed how to I transfer the file from my pc to the system/bin directory? I have been able to mount usb storage and it show up as a drive on my pc but when I mount /system nothing shows up. What am I missing?
Thanks for all your help! I am almost there! ^_^

hey, I recommended it first . Seriously though, download a kernel from the dev section, any kernel. Open it up in winrar, winzip, etc... and delete everything except the system folder. Now take the bin file u copied to ur computer and put it in a folder called bin. Put this bin in the kernel zip inside the system folder. Now delete everything else in the system folder. Put this file on a microsd, slip it in ur phone and flash it through cwm. this will put the bin back, and allow u to reboot phone

JDub... PM cdshepherd.... he's the one who shared with me you can use the mounts and storage option in cwm (then click "mount USB storage")... then you can copy files between your sd and computer without having to do what I did (which was pull external sd out of SR, mount in micro adapter, plugged into laptop and loaded files on the sd... then put sd back in phone.. booted into CWM and flashed the rom zip I put on there). Yes.. you are close! If you can't get that one file back to sbin on root, you could try to flash a stock rom/kernel zip (KK1 or LA3)... you only need to put that rom/kernel zip on your sd or external sd so CWM will see it.

icenight89 your right you provided the inspiration so I thanked you as well and appreciate the explanation. I will perform it now and see where I get. Let me understand this correctly in steps..
1. Download a kernel, any kernel.
2. Open it up, delete everything except the system folder.
3. Create a folder named bin and put the backed up file in the bin folder.
4. Delete everything else within the system folder except the bin file and bin folder. So it should be /system/bin/xxx.file
5. Put this on a microsd card and flash it through cwm. I assume I do this by selecting "install zip from sdcard?"
Thanks for the continual help! ^_^

I am having trouble with the kernel part. I downloaded a i727 kernel from here http://forum.xda-developers.com/showthread.php?t=1340114&page=2. Opened it up and it has boot.img in it. Am I missing something?

Alright. I downloaded the kernel from here http://www.mediafire.com/?85g701ate11zdc9. The kernel contained a folder named system and deleted everything else. I then added the folder bin and added the backed up file I deleted to the system/bin/ directory. I then mounted usb storage via CWM and put the new .zip in there. I then selected "install zip from sdcard", "choose zip from internal sd card" located the zip file and selected "yes." I then get the following read outs...
Installing update...
Installation aborted.
--Installing: /emmc/sgh-1727-skyrocket-att-original-kernel_2.zip
Finding update package...
Opening update package...
Installing update...
Installation aborted.
So it looks like it is not installing. Am I doing something wrong?

wrong kernel, download this one:
http://faux.androidro.ms/sky-kernel-010b1.zip
delete everything from in there except system folder, including boot.img, and follow instructions again, should work

these steps are exact, nice

Unfortunately I get the same error message with the kernel you supplied. x.x

Installation aborted.
Are you sure I can just delete and add stuff like that and It will work? I mean it makes sense to me but since it keeps aborting there may be something crucial missing that I need to keep in the .zip file. Any ideas?
Here is a link of my modified zip. http://dl.dropbox.com/u/6778642/Android/sky-kernel-010b1.zip

pm me when u get a chance

download a rom from Dev section. Doesn't matter which one. Try silvers rom you'll like it. Mount USB storage in cwm. Copy rom to sd. Eject SD from computer. Go back to main menu in cwm. Wipe data/factory reset. Wipe cache partition. Wipe dalvik cache(under advanced in cwm) format system under mounts and storage. Back to main menu in cwm. Install zip from sdcard. Choose zip(rom) you just placed on your SD. Flash it. Reboot device. Enjoy. And make a nandroid after it boots for the first time.

Did you make a cwm backup of rom you were using prior to this?

No, I did not make a nandroid backup. I had to install CWM from download mode and then I was able to get into CWM all without booting.
I appreciate your time in writing a solution however I am not interested in wiping everything and starting from scratch which is what your proposing. I simply deleted a file in system/bin named mediaserver so system/bin/mediaserver. When I rebooted the phone would not boot. I made a backup of the mediaserver before deleting it and placed it in the sdcard/download folder. All I need to do is copy the mediaserver file back to system/bin/ directory and phone should boot backup as if nothing ever happened. That's is how I understand it. Its just missing a file and I know what the file is and I have the file I just need to figure out how to copy it back over to where it belongs.
I do know how to install stock and other roms but after spending numerous hours on my first phone, SGS Captivate, to experience others roms like Darky's Rom the end result was that it was not worth me having to keep up with all the releases and bug fixes, loading in working kernels to make things work correctly and the like. I would rather just stick with stock. Its just a personal preference.
If anyone knows how to copy a file from my pc or from internal sdcard to my Skyrocket using Download mode or ClockWorkMod using any means but without wiping my data please let me know. Eventually if I do not get a solution I will be forced to revert back to the stock rom but I would rather leave that as a last resort.
I look forward to any other suggestions!
Thank you!

Without the ability to push/pull with adb your running out of solutions. I do hope that you get your skyrocket up and running no matter what method you use. And I do hope that someone with the ability comes along to help you. My way is prob the easy way out. If it were me ide cut my losses. Start from scratch, and try to figure out where my prob starts. Good news is there is a great community with plenty of help. Good luck mate.

Since my zip suggestion didn't work, try flashing a different kernel, romracer stockish 0.3 is a good choice, from cwm

Based on your first post, I don't think your pc is FULLY installed your device. Download mode requires additional drivers.........adb devices should return a serial number.
I have not tried adb on my skyrocket...I will do that for your sake and reply with my experience..

rom manage recovery problem

I cant go to recovery through Rom Manager for some reason. It works manualy( power+volume) but when I click it from the app it freezes, and shows an exclamation point triangle

have you tried to reinstall the app?
Wich CWM do you have?

thy the above post; if that doesn't work, go into recovery manually and fix permissions

that must be why
I was following this video http://www.youtube.com/watch?v=PVyGw6vycFo
and it said I had to wipe my data which I did, and maybe CWM was removed?
Ill try to flash CWM and see what happens.

Worked! thanks

In wich way?
Have you reinstall Rom manager App or reflah CWM Recovery?

actually, theres been a trend going on here....
I went on recovery to check if its working after I flashed it and it worked, after turning it off and removing the usb out of my computer I tried again and it didnt work.
Any ideas why?
Edit: when I had ROM manager I already tried to Flash CWM there if you're wondering.

Rename /etc/install-recovery.sh to something else with your preferred file explorer with root capability. Now reflash cwm and it will stick. What you are seeing now is stock recovery.

where can I find /etc/install-recovery.sh and what do you mean by file explorer with root capability?

Root explorer, ES File Explorer or something of the sort. This will let you directly modify files on the /system partition. Just enable root functionality in the settings, allow root when the popup comes up and rename/delete the /system/etc/install-recovery.sh file (this is the correct path, /etc is a link to /system/etc - ignore the other one).
Directories work pretty much the same as windows except it doesn't use "drives" (ie, C:\, D:\, etc), everything is found within the root directory (which is /).

fairly new to android so I have no clue what you are talking about sorry... can you give me some steps on how to do that. again I apologize, Im still new

Download this from the market, i'm sure you'll figure it out

quick unrelated question: I tried to apply the ROM and it didnt continue, it said it was aborted or something

Will not Boot into CWM

Ive been trying to install Glorious overdose for three days now and no matter what I do, I cant get my SK4G to boot into CWM, im rooted, have rom manager and have the zip for GO 3.3 in my root folder but it just seems to boot to normal recovery no matter what I do, any help please? I read that rom manager doesnt work, is that still true?
Thanks

Have you overwritten the stock recovery file on your phone? You'll need a file manager that can use SU in addition to root access. Also, you'll need to mount your internal storage as rw in order to overwrite the stock recovery using the root file manager of your choice.

Alright, bear with me I am a mega noob, I pick up on thigns fast though.
I have ES File explorer, and downloaded total commander, I tried to overwrite the recovery file in the system/bin and it says SU error, only giving me the option to Skip "failed /mnt/sdcard/sdcard" cross device link
Im not really sure how to mount/ unmount

I would download Ghost Commander from Google Play. It supports SU mode and is free. Most options to do anything can be accessed through the menu key. You'll have to enable root/SU mode in Ghost Commander since it's not enabled by default. Plus, you'll need to copy the file in that app and mount the file system as rw- (read-write). I forget the folder off-hand where the recovery is located at. *Standard Disclaimer*: Do these things at your own risk.

See, I still have no idea how to mount or unmount lol. And Ill try that, thanks
I moved file to bin with the ghost commander app, it had a #rw next to the bin folder name. Now how to check mounts?

I'm guessing you are referring to checking mounts during ROM installation? That is done in CWM itself. If it says # means you have root and if it says rw means you have read and write capabilities. Once you have that, move the recovery.bin you downloaded from krylon and move it to system. It should ask you if you want to replace existing recovery. Then once thats there and you have the update zip on the root (main part of your SD card, not a folder or anything), go into normal Samsung recovery and reinstall. Should take you to CWM if you moved recovery correctly! Thats when you need to check mounts.

I haven't used Ghost Commander, but I downloaded the free version of SuperManager 3.0 to move the recovery file.
If you use SuperManager, you just go to the file manager (slide to screen 4, top left), you will start out in MNT/SDCARD. First, click the menu button and choose "setup." You will see "ROOT" and click on it, check "Enable ROOT function" then you will be promoted by SuperUser [su] to allow access, hit yes. Back out of the menu so that you are back to the SDCard [note: sometimes you find that you are in the system file after enabling root, if so scroll to the top and click 'Back up level folder' then choose 'SDCard' If you get a popup which says "Switch system r/w" at the top, choose "R/W"].
Once back at MNT/SDCARD, scroll to the recovery file, click and hit 'copy'. Scroll back to the top and click 'Back up level folder' until you are back where the "system" file is located - top where it read "MNT/SDCARD" will read "/ (R/O)" or "/ (R/W)" and if it only shows "/" then you need to enable ROOT still. If it shows "(R/O)" at this level, that is okay. Scroll to "system" [if you have already been promoted to choose "R/W" you will likely notice that the top reads "/SYSTEM (R/W)"] and click to enter, click "bin" to enter, click "paste." If you have not already been promoted to do so, you will be promoted to change directory to R/W [read/wright, versus R/O read only]. If it asks about replacing the file, choose whichever option replaces the file, you do not want to save with a different file name.
If you are using a different file manager, you may find the process very similar. Good luck! Glorious Overdose is a good ROM [though I have not used v.3, I have used v.2 and really enjoy it].
You may find this thread very helpful.

[Q] I can't get my cwm to work...

Hello,
I am having a minor problem, I am a newbie to rooting and things a like.
I've been trying to setup cwm recovery and I go to stock recovery and I select reinstall packages,
it will work for a second and then it will say "Whole signature failure: Installation aborted"
And then it will automattically reboot. Any help will be appreciated!

Two things, you must:
1. Have modded recovery binary
and
2. Make sure you are using the correct CWM 3.0.2.8
EDIT:
http://www.mediafire.com/?mex4qna8rr3urck Modded Recovery
http://www.mediafire.com/?jvtpra5ashdmctn CWM
Make sure you change CWMx.x.x.x to update.zip and the modded recovery must be placed in /system/bin
Backup current recovery file and make sure you overwrite with this, using a file explorer that allows you to get to root access.

One thing to remember about this is that you MUST mount the internal storage as read/write. Ghost Commander (free on Google Play) lets you do this. You have to enable root explorer in its menus, and then go to where your stock recovery is and mount the volume as read/write. Then, paste the modified recovery in the directory and overwrite the stock one. Now, you should be able to get into CWM.

First things first: did you successfully root your phone?

No some permissions are unable to change because it is for safe purposes because you might screw up your phone if you change the permissions or there is a duplicate file of it

ok... i think there is a newer one in development section, with superuser 3.1.3
but i don't know if that is the problem, anyway you can redo the whole process of rooting, starting with flashing stock or you can change the app
i use root explorer and it works nicely, never had a problem with it
another thing you can try is flashing a custom rom, maybe its a firmware problem
