First this is the wrong section for this. Second just restore the phone back to stock.
Click HERE !!!!!
Before you do this turn off your device, press volume up and power at the same time !! That should take you to Bootloader Menu !!
I recommend you to stay stock, if you have no experience rooting, flashing or unrooting don't try again BEFORE educating yourself more.

Try going into clockwork mod mount USB in advanced menu download a new rom put it on your SD card and flash it. Just so u know this belongs in q/a not development.

Install the drivers on your computer. U cand find them here somewhere and hold volume up + power and try to use fast boot to flash cwm

Can you access recovery by holding volume + and power? If so, just wipe everything and reflash the rom on your sd.

Im new to this also but im running EC05 froyo on my epic 4g and i rooted it lastnite to SyndicateFrozen 1.1.0 Twilight 1.1 kernel jst by looking at the youtube vids and coming back and readin this site. Its fairly easy honestly...let me see if i can post a link. Oh and have u tried to boot it into recovery urself by turning the phone completely off holding down the volume buttons, camera and power button until it turns on that will put you into recovery mode jst make sure you already have your file saved to you sd card or your gonna have a nice time converting back to stock like i did lastnite lol. Are you familiar with Odin?
You 2 should not be rooting your phones. All phones are different, and neither one of you posted what phone you have.

[Q] I Think I KIlled MY G2X HELP!!

I was Removing Tmobiles built in Apps when I acidently deleted the telephony apk. I rebooted to see if the the devide would restore the file then it began to boot loop. i pulled the battery like three times then i tried to power on using both volume buttons and power and the device never turned back on. Is there a way to fix it? Please anyone who knows something can you help?
Try resetting your device. Turn it off then turn it on and keep the volume down button pressed.
The phone wont turn on now
Take out battery, hold both volume buttons down and plug usb cable in

About 47 minutes, until your screen rapidly starts changing colors.
first off wrong section.
not sure if it works with this works with this phone but you can try oden.
you will have to find a oden flashable rom and boot your phone into download mode.
or you could put your phone in a microwave for 10 secs and take it back to the store and tell them it wont work. they will replace it as long as the water meters arent red.
Look at the post for one click installing clockwork mod and do that. Then find the post with the stock nandroid (or eagleblood) download it either put the files on sd via a reader or boot to recovery and use adb push to get the files on the sd card.
Then wipe the data and cache and apply the new rom. That should work. Don't use Odin as that's only for Samsung phones.

Do you have clockwork recovery installed via nvflash? If not, you need to do that, then download the stock rooted backed that is posted in the development thread...Once you do that, download SuperOneClick and unroot your phone, you should not be messing with this stuff if you don't know what your're doing...After that, check out the stickies in the G2x forums and read the rules about what should and should not be posted in the each of the forums.
sorry about the miss posting never posted before and thanks for the help.
still no success i cant get the phone to stay in recovery to flash nvflash im pressing power and down volume but the phone reboots and begins to boot loop again
You don't go into recovery to flash nvflash. You hold down the volume buttons while plugging it into usb with the battery removed. Search for the thread on one click nvflash.

Solid amber light with no/long boot

I know this title comes up a lot but I can't seem to find my problem.
I wanted to go back to the stock rom and I used the proper RUU but totally forgot to use the S-ON tool before hand. It installed successfully but now I get a solid amber light and so far I got my inspire to boot once only to get stuck on the splash screen with it vibrating non-stop.
And now it just vibrated once, went to a black screen and then shut off. I really don't know what to do since I can't even get to HBOOT nor will the computer recognize it.
I've done numerous batter/sim card pulls as well as clean them out.
Any help would be greatly appreciated
Have you tried booting into the bootloader and doing a factory reset?

I think he was referring to the bootloader as HBOOT. I had this problem while rooting my sisters Inspire. Might be a corrupted bootloader.

Last I remember my bootloader was TWRP which I guess I had accidentally installed somehow. If you think its a corrupted bootloader how would I go about solving this, if there is a solution?

It seems that the RUU you flashed was a Froyo one and your phone was running GB so you messed the bootloader. Hit the Hack Kit IRC channel (is in the OP thread) and we will lend u a hand to fix that....
Alright so I went to the IRC and they told me they couldn't help because it did not deal with the hack kit, fair enough.
I have been able to get the phone to boot after waiting for about 10 minutes but I cannot get to the bootloader. I tried rooting the phone again this way I can turn s-on then flash the stock rom again but the phone ends up not being detected half way through the process.
I really don't know what else to do...
Forgot to mention, now my inspire boots but then fades to a greyed out screen. My computer recognizes the phone as something occupying the usb port but is not accessible. Wish the phone had a physical reset button somewhere that i can poke with a paperclip...

I will get back on the IRC this evening when I get home from work thanks again!!!
Does it say anything about QHUSB_DLOAD USB device being connected?
I ran into a similar problem not too long ago, immediate vibrating followed by a solid amber light and no phone activity (nothing on the screen at all). I knew I had a backup in Recovery, but I couldn't even get into recovery.
In order to work around this, I did the following steps.
1. Deleted the PD98IMG file from my SD card (so I could get to recovery once I made it to the bootloader).
2. Take out the battery, then put it back in.
3. Plug in the phone, and let it sit for a few minutes.
4. Start into bootloader (hold power + Volume Down)
Now, in my case I was just trying to get back into recovery. if you don't have a working recovery, or no ROM to flash, you'll want to grab a few RUU 's to try from the bootloader. Try stock GB first, then try a stock Froyo just for the heck of it.
Hope this helps! Good luck to anyone else that's stumbled into this problem.
side note: I've also heard of this "power problem" occurring to other people without bootloops or screwed up bootloaders: which is solved by doing steps 2 and 3, then it'll boot up normally.

Stuck at intro screen. Bricked! Help!

OK so I used the CWM recovery to flash the GenericGinger2.0 ROM and since then my phone wouldn't boot up. My recovery became the red voodoo recovery i gues... and it kept saying cannot mount SD card when i try to recover the backup i created before all of this. then it finally let me go back to the orange CWM recovery. it tried to recover my backup, but froze. now I am stuck at the sidekick 4g screen that comes on when u start the phone. BRICKED. what the hell can I do?
Sorry, best bet is to odin, and reflash the original stock rom and kernal. No hope getting your recovery fully back. Did you check your mounts ??

if you figureanything out let me know. im totally stuck right now. still cant find the rar.md5 file and still cant even boot into download mode to use ODIN anyway. even when i plug it in to charge, it freezes at the first charge icon (empty battery) so im thinkin its worse than just a simple solution

I got mine to go into Download mode as like this, Take out Batter, **Plug Phone Into Computer USB** then do the VOL - + Power + Track Ball
My problem is I also can't find the KD1StockODIN.tar.md5 that was originally used in the process =/ . Let me know if you come across it.
Thanks in advance.

I think I'm bricked, what should I do?

I flashed a Jellybean touchwiz rom for Verizon GS3, and went to reboot and now nothing, zero zip nada. No charging led light, no way to get into recovery and no response.
Anything I can do?
what happens when you do vol up + home+power button?
Absolutely nothing. I tried to get back into the recovery to see if I could restore my backup and nope.
did you try leave it pluged in for 30mins ?
does it vibrate once when you try to turn it on?
No vibrating and no sign of life at all. Even when plugged into my computer, I was going to try the unbrick guide but it listed that I should be able to get into the recovery still.

leave it plugged in for a while to make sure its not drained battery
do you have a usb jig?
I don't have a USB jig but this is possibly good news. I removed the battery and SD card and plugged it into my computer and it tried to install drivers (failed but tried) and the led light comes on red.
if your gettin led now you more then likely need to let it charge
It doesn't give me the led with the battery in
Plug it into a wall charger for at least 30 or even better if you can get a battery from someone.

I think its gone still nothing.
red led means qualcomm download mode. sounds dead to me
Yeah, haha. I saw it and mentally prepared myself for it. Literally just got the phone today so Verizon had no qualms with just sending me a new phone. Guess I'm reactivating my Rezound in the meantime. Thanks for the help guys.
you know
I am surprised. That also happened to me the first time i flashed that very same rom (touchwiz) with twrp . I have done this so many times , i literarily can flash a rom on the way to work .
I was in shock , i still dont know how the heck can i flash a rom and brick .
I plugged mine into windows and i got the device manager driver error from hell . and my phone never came back up again
I stayed away form twrp and touchwiz and i still cant possibly comprehend how a simple rom flash can brick my phone .
Which ROM did you flash?

you could probably send it to get Jtag'ed for around $60 if your warranty is invalid (ie used device)
You just hard bricked it. I did the same thing. Check here - post 5 shows the same symptoms :http://forum.xda-developers.com/showthread.php?t=1770341
And here: http://forum.xda-developers.com/showthread.php?t=1791721
I was pushing a copy of root66 that I hadn't md5'd. Took a JTAG to bring me back (twice) .
Sent from my SCH-I535 using xda app-developers app
So, in the future, md5 checksum absolutely everything since I'm assuming now that that is why this happened? (Since I made doubly sure I was flashing a rom for my phone).
If you still have the file you downloaded, you can check it. That would answer that question. If it checks out fine, then we have to look elsewhere for the problem.
BTW, MobileTechVideos.com can bring you back - based on my experience with them, I highly recommend.

Please share exactly what you did so others can benefit from your unfortunate experience.
What ROM did you flash?
Did you use ODIN or a recovery?
If recovery, which one - CWM or TWRP?
Was there any unusual condition you can think of ... low battery, USB connected to computer or to charger, etc?
