[Q] Totally messed up my phone after attempting to get root.

I just tried to use this method on my Inspire today and there was an error when flashing back to the stock AT&T ROM after gaining S-OFF and root. When I try to start up the phone normally, it gets stuck on the HTC screen. When I try to boot into recovery, it just shows a black screen while the LED is green.
Anybody know what I can do to fix my phone?

which root method did you use?

I used the one click root method.

Sorry your link doesn't seem to work.

If you press the down volume and hold power can you get to hboot?

Try using bubby's tool to fix the CWM black screen. Its under the fixes link.

I can't seem to access any sort of recovery or hboot. Holding down both volume buttons and turning the phone on will result in the black screen with green LED. Holding the down volume button and turning the phone on does nothing.

Sorry go to Bubbys super one step and search for CWM black screen....

If it helps, the phone vibrates 5 times then shows a black screen.

Well I was able to get into HBOOT but when I tried to go into recovery, the screen would just turn black.

You need to get the stock rooted PD98IMG.zip into the root of your sd card. Then go to hboot and let the phone find it. Follow on screen instructions. Note the progress bar will be vertical on upper right. I bet that fixes you up on getting the phone working. Black screen on cwm is a whole nother issue. One that I share. I think I'm going to revert to stock unrooted and then our attn1 hack kit.

There is a solution you can eng s-off, but I would not advise this there is no need to eng s-off your phone.
The simplest way though it may take longer is to, revert to stock and reroot and s-off with the hack kit.
This is a very common problem with the one click. To be honest there is a thread made just like this twice a day.

Thanks for all the help everyone. I managed to fix everything on my phone. I just flashed the rooted AT&T stock ROM with HBOOT and then used the one-click ENG S-OFF method to fix the black screen on CWM. Now running CM7 perfectly. I'm glad I no longer have to send it back to AT&T.

kinder gentler XDA i guess. Last year posts like these would have been flamed right off the board. Thats not a bad thing, but new people are wasting everyones F'ing time with these posts.
RTFM! w/e it is you decide to do , how about looking for help in the dam thread you downloaded the stuff from? I duno maybe we have a bunch of people brand new to Forums or something.

Ok I don't mean to thread jack, I just didn't want to start a new thread for this. I've been running the Coredroid Rom since I first rooted my phone. I have never had any problems with my phone even when trying out other roms. Today I tried installing the new Coredroid 5.0. It all went well as usual except this time on the last step of the setup wizard, it said something like "setup has stopped working unexpectedly and will notify HTC" and only let me press ok to force close.
After that happened all I couldn't even go to my home screen. I then tried restarting my phone but got stuck on the Coredroid rotating logo. Only way out of that was to pull the battery cover. Tried going into recovery mode but the screen would just be black and I would have the orange light flashing. That didn't work so I tried restarting again. Again just got stuck on the spinning logo.....This is where **** gets weird. I began to receive a call while on the logo and that allowed me to answer thus leaving the spinning logo. I still could not go to my home screen. I could only use the drop down notifications menu. I restarted my phone again so I could call myself while on the logo and again it got me unstuck from the logo. Only way to fix every thing was to use the search option and run Rom Manager and recover from my previous back up.
So I was wondering if this has happened to anyone else? I always fallow instructions and hardly ever have any problems but this was just odd. I felt like I had to solve riddles in order to get my phone working again.

See if you can boot to bootloader by means of ADB (adb reboot bootloader). If so reflash the stock rooted rom then reload CWM. You might need to Eng-S off if you have a corrupt file / bootloader? When done reflash CorDroid 5.0 (What I am running by the way)....

black htc screen
I tried to root my phone like an idiot because I dont know anything about this stuff and I got a black htc screen and i cant do anything. HELP!!

I see a lot of motivation in this and other threads to leave well-enough alone. Going to leave mine unrooted-stock.
I just had an excellent session of Google Nav where it performed exemplary. My phone does all I need and remains within the rules as the OEM wants it.

[Q] bricked htc inspire frozen on htc boot up and cant get to fastboot

hello.. i have looked for the answer to my question but i cant seem to find it, therefore i created this post.. sorry if i posted in the wrong section or if it is already out there.. i hope mr clown doesnt close my thread.
i rooted my phone doing it with the one click tool, and it worked perfectly fine.. the problem started when i tried to install a custom rom on it.. i installed rom manager and cwm fine.. but the problem is that i was following this instructions..
http://forum.xda-developers.com/show...php?p=11557769
which i read i had to get this rom...
http://forum.xda-developers.com/showthread.php?t=868720
the problem is that i didnt realize that i needed eng s off and i had s off wich therefore i wasnt able to see the cwm screen..
following the steps that told me to wipe the data with the wipedat.zip.. i did it through rom manager.. when the phone rebooted it went to a dark screen slowly so i took the battery out, and now is frozen in the htc logo... i have tried the up/down/power combo but the phone vibrates 3-4 times and then it goes to a black screen with the light on... but i dont get anything else.. so im really stock at either htc screen or black screen... i need help!!! i hope some one nows a good way for me to fix this.

have you tried...
adb restart fastboot
or adb restart recovery or whichever it is
someone more familiur with adb can explain alil more on this

Download the stock ruu exe and run that from your computer.
Sent from me using this thing.

Try running adb reboot bootloader but first off run adb kill-server then adb devices to see if it is picking up your phone. If that doesnt work download the stock ruu and run it, hopefully all goes well with either method.

Just FYI - this was taken care of over in the General Forum.
Haven't heard from him since, but he was able to get into hboot.

Hey man i had a problem like that i used ace hack kit v9...Just do everything over again and it will work..

This is in the wrong section. Questions should be posted in the general section.
Its not volume up/down/power. Its just volume down + power. What is sounds like you did was restart your phone while it was trying to flash the rom. You should be able to get to the hboot menu just by holding power and volume down to power up the phone and wait till hboot shows up.

This will be probably the best answer I got.
1. Turn your phone off
2. Take out the battery and insert it back it
3. Don't turn your phone on
4. Plug in your USB cord,connected to your computer
5. Your phone will Automatically Boot up
6. You will be in the ClockWork Recovery
7. There will be many options
8. Select "BACK UP AND RESTORE"
9. Restore EVERYTHING.
10. youre phone will start normally, but it will be really LAGGY
11. Then ROOT your phone again to make it normal.
What has happened to yours has happened to mine. This is the way I fixed mine.
If you have any problems or issues, PM ME

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.

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.

im having same issue i have gb stock and i accidtly did froyo ruu phones power bottun does nothing i have to plug it into computer and it will get solid amber light then eventually it either brings up battery charge icon and then if i press power button or unplug it. it just shuts off the i plug it back in and wait sometimes white htc screen comes up and it vibrates for a while then boots ad works like nothing is wrong but i cant flash gb ruu when i try to do that or re root and go to recovery to reistall ics that is on my sd as soon as phone restarts during process it doesnt reboot then i have to go threw whole procss of trying to get it to boot back up

The same thing just happened to me. How can I fix this thing?

Same thing here, downloaded the update fine but when installing got to about 0% and phone locked up with a big red x. Hard reboot got me back in but says update failed. I am rooted but not unlocked, will this affect anything (other than breaking root).

Hard reboot is where you hold the power button for ten seconds right? Because I did that like 5 times. Factory reset is my last option. Maybe I could try running the 1.85 ruu if that can be provided to me and tell me how to use it

I had previously rooted by ONE S T-Mobile version and it had been working fine. I then decided to try out another rom. I likely flashed an incorrect boot img because it would only reboot into fastboot, but would still allow me to go into recovery. I went to recovery and restored my nandroid backup; however, now the phone will get stuck on the opening HTC screen the red language on the bottom, "this build is for development purposes only." It will hang on this screen for about 20 seconds and then turn off. No loop. When I attempt to power up again, I get a quick horizontal flash of light across my screen and then the orange LED comes on in the top left corner indicating the phone is charging. I then hold down power and again the phone gets stuck on the opening HTC screen with the red language.
Any advice regarding a remedy would be much appreciated.

When p hone is on you'll have to power it off manually by pressing power for 10+ seconds. Then you should be able to enter the bootloader and fastboot. (Vol down + power) No matter if you have flashed a wrong kernel.

Thanks for the advice on how to enter the bootloader. Unfortunately, no matter how many times I try, using your method and a variety of other methods, I still can't get past "HTC developmental purposes only" screen. I'm not new to android and have experience with a number of phones, but this is my first HTC. Pretty frustrating thus far.
I'm to the point where I'd love to send the phone to someone who could RUU it and send it back.

Thanks for the help.
Thankfully I finally figured out how to consistently get my phone to enter into Fastboot; however, no the trouble I'm having is finding the proper RUU. I've tried the 3 T-mobile varients available in the RUU depository found here
http://forum.xda-developers.com/show....php?t=2094414
But alas, while I am able to run the RUU program, which enters my phone into a mode where the screen is all black expect for the HTC logo in the middle, I keep on getting error codes. Are there more than 3 RUU varients identified in the depository?
Oh, I should note that I was also able to get into recovery, but my SD was unable to mount so I can't find my Nandroid.
Also, while the RUU program recongizes that I have my phone attached, the Hasson utility does not, nor does my computer.

Please get the correct ROM update utility and try again.
I flashed the stock recovery and tried to use 4 different RUUs, but no luck.

You need to relock the bootloader before you run the RUU
And if your CID is Optus001 and you're S-ON you can't use T-Mobile RUUs (T-MOB010)

I got my phone back! Thanks for the help. Your advice was spot on. What a terrific community of people. I hope that others will be able to follow this thread and fix similar issues.

Thankfully I finally figured out how to consistently get my phone to enter into Fastboot;

How did you enter the fast boot?
I was playing with System Files because of the low mic volume problem, rebooted and since then the phone does exactly like yours: 20sec of "this build is for development purposes only" then it switches off.
All button-combinations tried.
The PC in Printer and Devices sees it as an Android Phone, Device Manager sees a HTC MTP Device, but I don't see it in Windows Explorer.
Adb do not see any connected device.
I guess I have to change the motherboard.
