In an effort to get back to stock I took things a step too far and now have a phone that won't power on. I had successfully rooted the phone and installed Rom Manager and flashed the clockwork recovery and immediately created a nandroid backup. Sometime later my phone started acting funny... usb connected/disconnected events when it was not plugged in, crashes, etc. I felt confident that this was a hardware issue (started after my daughter chewed on it when I wasn't looking). Anyway, I followed the instructions here in the dev forum (True Stock 2.1 firmware for vibrant) for the vibrant to get back to stock ( I apparently can't post the link because I'm new...) . So that I'd be able to try and get it replaced. I kept noticing that no matter how hard I tried clockwork was still installed... then I did the bad thing. I should have known better, but I made the rookie mistake and deleted the clockwork folder from the internal flash. I don't know what possessed me to do it, but I did. Since then the phone doesn't seem to boot. I can get it into download mode to flash images from odin (battery out, battery in, volume up + volume down, connect usb and download comes on). And after a successful download it seems to restart ok. But if it crashes (which it is now prone to do) or is powered off it won't boot after that. Worse I can't get to the stock recovery either.
I'm hoping that someone who has a nice rooted stock phone with clockwork installed can just help me get a copy of that folder back and everything will be fine... if not I may just have to see if playing dumb with tmobile will get the phone replaced as is...
Thanks in advance for any help.
Are you talking about stuff in /sdcard? If so, that won't effect the boot. You could delete everything in there and not change anything. Some apps might not work as you will have deleted their data, but if you're flashing a stock ROM with Odin, that's fine.
Enable debug mode in the settings and use "adb reboot recovery" at a command prompt. That should get you to the stock recovery. Try a factory reset from there, that might help. If not, delete anything in /sdcard that's not supposed to be there and swap with TMobile as it sounds a hardware issue at that point. Don't forget to keep your external SD card if you've replaced it.
Is USB debugging on?
When you get the phone up, can you connect to it via ADB and then adb reboot recovery or adb reboot download?
Thanks for the suggestions. I did get the sdk installed and used adb to reboot into normal recovery, so it's not completely boned. Since I could use adb for resets I went ahead and followed the rooting process again and reflashed clockwork. The phone still won't boot on it's own. I'm starting to think whatever was going south with the hardware has continued to get worse. I'm going to use odin to get back to "true stock" again and try to use adb to reboot into recovery and do a factory reset suggested above and see if that helps.
Thanks again.
I went back to stock with odin, ran the factory reset, and still can't power up normally or into recovery. I can get into download though, load with odin, come up normally after the reset. I'm going to try giving it back to Tmobile in it's refusing to power up state and see if I can get them to swap it. It's as stock as I can make it so the problem should not be mine.
Thanks again for the help.
FWIW - i just installed Rom manager this morning, the premium version, and today experienced 5 force closures, one on google maps
before this i've had maybe one FC some 2-3 weeks ago - and like you i did a clockworkrecovery backup or nandroid backup

Hi,
Just wanted to share my experience getting JPC Rom installed and rooted.
Prior to upgrade, I had the JP3 Rom, rooted with clockwork and 1-click lag fix.
I had some major issues installing JPC. In fact, I ended up with the dreaded USB logo a few times.
This is not a complete guide, but hopefully it will help avoid the problems I had.
1) Before installing the new rom, I strongly suggest that you Factory Reset the phone.
2) Install the JPC Rom using the other guides on this page. I used Odin and choose Repartition to get a clean install.
3) Here is where the problems started. After the rom installed cleanly and the phone rebooted, it would get stuck on the second Samsung logo and eventually go black. This happened to me twice. The fix I found out, is to go into Rececovery mode (Vol Up, Home, Power) after the install and clear the cache, reformat SD and factory reset. After you do this the phone will boot normally.
4) After that I followed the rooting guide on this forum, but ended up with the dreaded USB logo. If this happens to you, just go back into DOwnload mode and reflash with Odin again (following the guide in this forum)
IMPORTANT: I have TWO galaxy s phones. The strange thing is, one of them is VERY easy to get into Download or recovery mode. The other is almost impossible. For those of you that have a similar model to me that seems like it does not have a 3 button download or recovery mode you probably do.
I thought I was bricked, and tried for over an hour to get my second phone into download mode (take out battery, hold three buttons, put in battery, over and over again). I was about to give up, but found I was able to get the phone into download mode if I ....
1) Take Battery Out. Put it back in.
2) Plug phone into USB on computer (do not turn it on)
3) Now try to do the 3 button Download mode. Press all three buttons at one time and release power about 1 second after seeing Samsung logo.
Again my second phone I can very easily get to download mode 100% of the time. I am really not sure why the two phones would be any different. I hope this helps people that have a stubborn phone like mine.
P.S. I did not install Clockwork on JPC, but I did root the phone and installed 1 click lag fix. Phone is running VERY stable and all features seem to work (including Mobile AP).
I hope this helps others like me who tried to install update.zip as explained in some posts & got the dreaded USB logo on boot & didn't know what to do because I am sharp but no programming & all that. I got mine to go ahead ONLY after I put in my SIM & External SD card. With both OUT, I get the USB logo 100% of the times.
I hope this helps.
Ive installed jpc a few time now and a factory reser after flashing did it for me every time
ok..im new to the galaxy and android phones .. i bought the phone rooted..not sure all what it had but i was running i believe a different rom on the phone, 2.1 update 1 i believe, it had rom manager and clockwork recovery on it, anyway .. i tried doing the lag fix and now the phone just turns on and stays on black screen.. keys at the bottom stay lit up also.. i can get into recovery but not really seeing anything in there that is helping.. can i factory reset or something from this recovery screen? like i said im not real familiar with these phones but im good with directions so if someone can explain how to fix this that would be great! thanks!
Hi, did you try using odin to flash back to stock?
the files you need to flash are in this thread
forum.xda-developers.com/showthread.php?t=734475
Also make sure you have samsung drivers installed on your computer. Which can be located here forum.xda-developers.com/showthread.php?t=728929
A stable version of odin is in this thread
forum.xda-developers.com/showthread.php?t=790026
steps
1. you will need to download odin..open it
2.Make sure your phone is off. connect your phone via usb and get into download mode(hold the volume keys+power when screen turns black let go of power button) now you should see a yellow triangle with android icon
3.to make sure your comp recognizes the phone.. pull out usb and put it back into the phone.
4. look at the first link i posted and flash the files accordingly and you should be good to go.
ok..i will try it. unfortunately i use my phone to tether so now im back on my blackberry which is SLOW.. odin is saying like 4hrs to download..loL!
I had the same issue. It sounds like you didn't install a BusyBox version that has extfs support built in. I could swear that the lag fix option I pulled down was supposed to have it, but it didn't. If you made a nandroid backup before you tried this, you should be able to get into recovery and restore. If not, you'll have to get to download mode and Odin flash back to stock.
If your phone is hardware locked, with the state your phone is in, you SHOULD be able to do an "adb reboot download" or "adb reboot recovery" to get into those modes.
A message popped up from Samsung to install an update (I had been pressing cancel for the past week on this update). It says click OK to reboot and apply update (something along those lines) so I do. Now I am stuck with a tablet that won't boot. If I hold the power button it says "Samsung Galaxy 10.1" after about 12 seconds, but then it goes away and back to darkness. Nothing else. Holding power and volume up does nothing.
Someone know what is going on and have any idea how to resolve?
The best way is to restore any backup you have from cwm recovery. Else grab a stock firmware and flash it with ODIN or if zip than CWM recovery. For luck, try clearing cache and data in recovery, first!Perhaps it may work saving you all fuss of flashing a firmware.
I cannot even boot that far too get into recovery. And I just noticed that although I can't boot, the backlight is on (on a solid black screen).... wtf
You can't hold volume down and power button to enter recovery?
Nope. I plugged into my computer and for some reason with the USB connectd it let me enter recovery. Flashed a backup and rebooted, but now I have no wifi... im confused.
it occured once to me when i tried to overclock, it never worked except when installing a new rom... Try to root the device and then install a new rom
OK, was a helluva night messing with ROM and kernel installs... I have yet to go back to completely stock (that's next up tonight, unfortunately), but I installed Starburst ROM and the Wifi still didn't work so I then installed pershoot's kernel and now when I boot the screen is extremely distorted kind of like this: http://t1.gstatic.com/images?q=tbn:ANd9GcTsKa5IoQxnesGdUjykWDDggoQZ38yZ2VXSgPAQ09NOCnETzl9-
As a side note, when I say the wifi is not working, it still shows all networks and allows me to connect just like normal. However when connected no apps can access the network...
Can someone point me to a thread on how to revert EVERYTHING back to stock so I can start fresh? TIA!!

Should have all the files you need. From where you are now I would flash the stock OTA 3.1 or TW then flash the stock recovery and do a factory reset from that recovery. That should get rid of the garbled screen.
Thanks buddy. On my way to grab the files now
I heard the update was pulled as it sometimes rewrites the bootloader improperly. You might need to send it in, unfortunately.
I rooted my G2 about two months ago. I'm currently using MIUI, not the latest but the one before it. Somehow, my phone got turned off and when I tried to turn it back on, it was stuck in a bootloop. I have a custom recovery image so I don't know if that affects anything. I tried to reboot into recovery by pressing volume down and power, nothing happened. I then did volume up and power. It vibrated three times and the orange light started flashing. I pulled the battery and now when I try to turn it on, nothing happens. So how do I reboot into recovery and so I can restore my backup? Any help/suggestions would be greatly appreciated.
Never pull the battery during something like that. It sounds like your bricked. Someone else confirm?
I don't think it's bricked. I plugged it up and then Clockwork came up so I selected reboot now. Clockwork came up again so I tried to restore my latest backup and the screen went black. I'm going to let it charge and then give it another try.
Ok good. That's lucky because whenever you pull on a boot like that, it usually bricks. If you have the option, try to re-flash your ROM. Maybe even try stock. If you were getting a black screen, it's most likely you flashed incorrectly.
Ok, I was able to boot into recovery and now I'm restoring my backup. I don't think I had a custom recovery image with this one so hopefully I won't get stuck in a bootloop. When you say stock, do you mean before I flashed MIUI (it was the first rom I flashed)? Thank you for your suggestions and all of your help.
first install adb on you PC, it helps a lot in these kind of cases.
1. try "adb logcat", it would tell you about what's going on in your machine.
2. once you get your adb working, try "adb reboot recovery" to see if it could boot your phone in recovery.
3. if after doing everything you fail to boot either your phone or in recovery then try using PC10IMG to boot a stock rom and then re-root your phone.
I got it back working. For some reason, I'm just starting to think that it needed charging (the battery had been out for about a day or two). I do have adb installed and configured on my computer since I needed it to root. Thank you for your suggestions, I will definitely rember them if this happens again.
lol of course when you get black screen and led blnking means your battery begging for juice, you're lucky that when the phone booted back in recovery and you tried to restore a backup the phone went off before actually starting to restore, that would've bricked your phone
DO NOT FLASH ANYTHING WITHOUT AT LEAST 40% OF JUICE LEFT
Good evening everyone,
I will start off by saying that I really didn't do things by the book this time around. I have run out of ideas even as to what to Google to find similar cases to mine.
I wanted to flash Cyanogenmod onto my G2. Since I already had CWM installed, I loaded the ROM and Gapps. After wiping the phone, I went to flash from the zip. The flash failed. I tried again, and it happened again. I wiped the cache and dalvik again, and tried again. Still no flash.
At this point I go for the reboot only to realize that my phone is now stuck in a bootloop that is contantly landing me back into recovery.
I believe I really screwed up from here as I read about a way to exit the cwm bootloop by flashing a new "exitrecovery.zip" file. Since ADP wouldn't push the file for some reason, I used that function where the phone waits the file to be pushed and flashes it. That succeeded.
The phone switched off (after hanging on CWM for a bit) and now won't do anything at all. No boot logo, nothing. Can't get into CWM anymore either.
The computer brings up a bunch off drives which it wants me to format when I plug the phone in. Only one of them has a folder called "image" on it.
The display switches on, but won't do anything there.
Holding power+up reboots it after a few seconds and so does power=down.
I am thinking of just seeing if I can get it assessed by my carrier, hoping they'll have the tools to just reflash it... somehow. Else, is there a way to potentially fix this?
Back to stock
Put the phone in download mode (vol up while plugging in USB) and use the LG Flash Tool to return to stock. Instructions are posted in General section.
Rule number 1.
ALWAYS MAKE A BACKUP.

I have a backup I made with CWM.
If that helps, please point me into the right direction to restore it. I fail to see how I can do that without even being able to start cwm up.
