[Q] Evo Buttons Stopped Working

I've seen a lot of these threads on random android forums, never with much resolution, which is frustrating.
My power button has stopped working entirely. I took it into the Sprint shop, they spent an hour with it, came back out and said they could find no reason it shouldn't be working. It's an obnoxious fix, but I downloaded "No Lock" from the marketplace and set the screen to shut off after 15 seconds. Now I press a volume key to turn on my screen...
Now, when it gets annoying is when I went to install Cyanogenmod 7 tonight. The power button obviously doesn't work. Widgetsoid's reboot button is ignored entirely if I do Shut Down, Reboot, Bootloader, or Recovery. It's A-OK with Hot Reboot. So the only way I've gotten into the bootloader to wipe/install CM7 is to pop out the battery, hold VolDown, and put the battery in. Peachy. But once I'm into the bootloader, now not only does power (which is now my "enter" button) now work, but the volume buttons are unresponsive as well. So no scrolling.
I'd love to call up HTC or Spring and see what I can do about a replacement (which might not even happen, I don't have a warranty), but I can't un-root the device to send it in.
Any insight you guys have would be greatly appreciated...

Is there an SDK or something that would allow me to remote control the phone using my computer via USB? I'm completely at a loss here.

I believe you are referring to adb?
and you can unroot via adb, just search around, I'm sure you'll find something on it.
btw, does Sprint know you rooted your phone? if they didn't find out, then you still have a warranty

Yeah, I'm just not as familiar with ADB as I'd like to be.
Not so much looking to unroot, as reload HTC Sense so they don't think to look haha. And yeah, when I brought the phone in today it was very obviously modded. They restarted it and the Cyanogenmod 6 flash screen came up. The guy looked a little confused. He was more than willing to help out, but I'm not so sure it would be the same if I sent it in. They definitely wouldn't replace it.

Alright, so I have ADB up and running with no issue. Got it to give me my device's serial #. At this point, how do I hijack the phone's bootloader and force it to wipe and install the ZIP of CM7 that's on the SD card?

[Q] Please help

My phones screen just stopped working and T mobile agreed to replace it but now i have to unroot it. I Rooted with Visionary and have S off, i found the guides to unroot but I cant see my screen for half the stuff i need.
Is there anything i can do?
Please help me.
Thanks in advace.

...deng that's not good. Since you can't see then I don't know. Maybe with sombody with adb knows as for me I don't know... you should not accept the replacement because if they find out ur rooted you will pay 300+ bucks

Ahhhh. Can someone please help me out? I remember when one of my older phones broke i found some program to pull up the screen on my comp. Is that possible with the G2?

That's adb. If you have adb you should be able to find the phone if you hold volume down + power. But from what I know you need usb debugging on

ADB is for like giving the phone commands. Im talking about a program that will bring up the phones actual screen on the computer and you can see everything.
Anybody else know what i could do?

Putting myself in this situation...I would pull the SD card, get it on the PC or whatever and copy PCIMG10.ZIP (or whatever it is - the stock OTA) to the root of the SD - put it back in the phone and start up in recovery (vol down + power). Then wait about 5 minutes (shouldn't be that long tho) until the phone has a chance to parse the PCIMG recovery file. After that I think the response is Volume Up to confirm the update?
The fact you rooted with visionary may be a deal breaker however with my Blind_Ota_revert_method(tm)
I guess, if at that point that bricked your phone, at least it will appear to any techs that you had/have OTA firmware on it...not sure though

Yeah I think I know what you are talking about, my old Vibrant had a TV Out feature to display the screen on any tv you hook it up to. Unfortunately, the G2 does not have this functionality out of the box or available in any custom capacity. It may be possible to manipulate the USB driver on the phone to achieve this, but I have not heard of a way, you'd need to talk with a dev to find out for sure.
As far as getting past this issue, your best bet is going to probably be to try to hard brick, but without a screen to work with that will be damn near impossible. I hope you're able to do it man, I would not want to be in your sitch. Good Luck.

The screenshots your asking about is DDMS, it's in the sdk/adb folder.
I've always worried about this too, I was thinking do what he said with the stock stuff but do the fastboot reboot bootloader command and try running it there. I gotta do a vibrant warrently here soon so I gotta do the same thing.
So you can't do that with visionary? I hope so... cause that's how I did it lol.

Question about Rooted G2

I have a question. My G2 Screen turned off and won't turn back on. I've tried everything but nothing works. The phone still charges and turns on but the screen is black. My phone is rooted. If I send it back to T-Mobile for a replacement, will they find out its rooted?

Possibly.
I believe there's a way to go back to stock without using your screen (via ADB).
Are you sure its turning on at all? To the capacitive buttons/keyboard buttons light up?
Sent from my HTC Vision using XDA App

Personally I had my first G2 malfunction on me after I had my phone perma-rooted. The SD reader no longer functioned properly so I couldn't access any data consistently which made it impossible to unroot it.
In the end I called tmobile and told them that my phone's sd card stop reading properly and they sent me a refurbished model with no additional charges to my account. I know for a fact that if put the phone on recovery mode you can definitely tell if the phone is rooted or not. If it's your last resort then I would chance it, but you're risking them sending you back another phone with a pretty hefty bill. (read somewhere if they find out that you're phone's been rooted, they're required to *keep* the phone)

Yes the phone turns on and the capacitive buttons and keyboard buttons light up. I can hear the sound if someone calls it rings. The only problem is the screen is black and won't turn on. If there is a way to unroot it via ABD that would be great. Do you know where I can find instructions on that?

Yeah that will be my last resort. But right now I'm trying to look everywhere for instructions on how to unroot it using ADB but no luck yet.

If anyone on the forum can point me in the right direction as to where I can find instructions on how to unroot using ADB will be great.

So I turned of the g2 and plug it in and webt into adb devices and it says the phone is in recovery. So if anyone knows a way to unroot this way from ADB would be helping me out a lot.

idk how to unroot via adb but have you tried putting a stock rom in the sdcard, go into hboot mode on the g2, even though you cant see anything on the screen just find a pic online of hboot mode, then move the volume button to recovery then select it, then you will be in recovery the select install zip and even thought u still can see anything you could do the same thing i told you to do for hboot mode, so then install the rom. tell if that worked. i have the same problem with my htc g2. if that doesnt work then its the lcd screen its self.

[Q] inc 2 with dead screen

So i recently got a free upgrade to a inc 2 by turning my og inc in under warranty for a blow speaker (for the third time) and i naturally rooted it and installed a nice miui rom. Now about a month later im out of town for work and the screen has died. The phone is still operational, but the screen is black.
I am wondering if this could possibly a firmware issue? i have tried pulling the battery and booting into recovery but the screen is 100% useless. the touchscreen still seems to work, i can unlock it and answer calls ect...
My hunch is that its a hardware problem, but i'd like to try and flash it back to stock if possible to eliminate the possibility of a rom issue.
Does anyone know a way to flash a rom onto it without the use of the screen?
Can i use the HTC sync tool to set it back to stock like i could with the OG incredible?
Any help is much appreciated, i'm pretty desperate here.

if it was me, I'd flash it back to stock using a ruu file, then do a warranty claim, cause then if it's a firmware/software issue the ruu will fix it. There's a thread somewhere around that has instructions to do that, give me a minute...

Sent from my Incredible 2 using xda premium

ok, so my new issue is that if i flash the ruu, and the screen still doesn't work, i'll be stuck at the setup wizard right? then i won't even be able to use google voice to make calls from my laptop. i guess ill have to wait till i get home, this would be so much easier if my pos nextel work phone had service out here in wyoming.

Yea, that's a tough one, I definitely wouldn't flash an RUU for the exact reason you bring up.
One option, although it isn't without it's own challenges, would be to try to install a VNC server on your phone, so you could then connect to and use it through a desktop computer. You could probably install it easy enough through the Android Market web site. Here's one: https://play.google.com/store/apps/details?id=org.onaips.vnc
If you download the Android SDK (http://developer.android.com/sdk/index.html), connect your phone to your computer, open a command prompt and run ddms, it'll bring up the Dalvic Debug Monitor. Here, you can go to Device>Screen Capture and it'll bring up a window showing the screen of your phone. There's a refresh button which will refresh the screenshot. It'll be a little hit or miss, but you should be able to reference the screenshot to tap on your blank screen to open the VNC app, hit the start server button, and then see what IP/port it's listening on.
Once you get the VNC server running and connect, you should be able to use the phone fairly easily, although if the screen is dead even during boot (no initial boot screen, no display in h-boot) it would seem like a hardware problem and there's probably not much you can do about it.

I ran into a similar problem with black screen over the weekend.
However my phone was not rooted.
This is how it happened.
I was using my phone then I saw the screen flicker once or twice, then it went black.
I pulled out the battery and powered up again.
The phone vibrated, and after a while the four bottom buttons light up.
The volume keys work and I could receive incoming calls, but the screen just stays black.
One thing to note is that my pocket was a little wet before I pulled out the phone to use.
Also that I did use my phone for a good 5-10 mins before it went black.
What I am trying to determine is if it is a software issue or hardware.
Are the bottom button lights separate from LCD screen, so that even if they light up it could still mean LCD is bad?
Any help would be appreciated, thanks!

[Q] I need help, possible bricked phone

I tried to flash the aokp m5 rom but didn't flash the el26 cwm file. Now when i try to boot the phone, it doesn't start. the blue light just lights up and stays light untill i pull the battery. I also tried to get into recovery and it just does the same thing. I downloaded odin, but im not sure what im supposed to do with it. if anyone knows how to help, i would be extremely grateful. Thank you

Pull battery, put back in, hold volume down to get in download mode, start Odin on pc , plug in phone, press volume up, Odin should respond with COM# click the phone button and select your stock from such as the cwm el26. Just read the forums. Don't feel bad it happens to all of us once in awhile. Thankfully I have managed to fix most of my screw ups. Next time just read everything and save yourself hours......experience
But then again that could make it worse. So for ya sake use the search button

My phone doesn't allow me to get into download mode mode... Does that mean it is bricked?

Well I have more than once brought my device that I though would never come back. I know I have got ton my phone and my friends att infuse to connect to Odin without actually getting a screen on the phone and was able to get a recovery to restore the phone back to normal. From my experience though its been hard to brick these things... I sometimes wonder if people bricking is just user error.... knock on wood....

I don't know what that other guy was saying but you have to hold the volume down Button and the power button until it shows the custom OS menu the press volume up and then download sfhubs one-click EL29 and then open it, its in development fyi, connect your cable to your PC and your phone and the program will have a yellow box light up that will say COM#, don't worry about the number next to COM, then press start and wait until it reboots. Do not unplug the phone or close the program. If it works for you please respond back here so others can hear the results.

Is your phone recognized by adb? Maybe try "adb reboot download"?

Also if you read up about a jigg for the epic touch, in case this doesn't work, them that could also fix it. You might need to spend something though but I can't clarify this because i've never bricked before.

Yea he's explained it better than be. I'll just be posting from my laptop here on out. On screen keyboards kill me. I miss my g1s QWERTY. Ah well.

I press volume down and power but the custom os screen doesn't show up, all the phone does flash the blue notification light and the screen looks as if it is off.

This isnt something that a jig can help and for everyone else trying to help he cant access download mode or recovery.
You're most likely hard bricked and the only thing you could try is to leave the battery out overnight then try to turn the phone on again. If you still have black screen with just the notification LED on then the last resort would be a jtag service which isnt guaranteed to work either.
This is a known issue from wiping any partitions on an ics kernel.

What would a jtag service be?

You're going to need a USB jig to get your computer to recognize your phone to download the firmware over the current one. Wait till tomorrow if someone doesn't respond because i'm assuming all the devs and admins are knocked out and they are the ones who can help.
Sent from my SPH-D710 using xda premium

Geez a lot got posted while I was typing.
Seeing as how you can't get into download mode or recovery I'm afraid you're out of luck. (unless the jigg thing works, which I don't think will at this point)
This is a hard lesson to learn but exactly why you don't take any shortcuts when flashing custom ROMs.

What is a jtag service, and how would I go about it if I tried to get it done?

Thanks for helping them out! Its late and I forgot about the overnight battery pull and jtag.

Do a search in this forum, since there's been a lot of bricking I'm sure you'll find a ton of threads concerning this.

http://mobiletechvideos.mybigcommerce.com/samsung-epic-4g-touch-jtag-brick-repair/
Thats one of the companies offering jtag services. I believe some people have used it before but im not sure of their results.

Yeah, I'm only sixteen, so I'm trying to grasp all these different things. I'm used to htc because i had an evo, then i got an evo 3d. I use the e4gt as a second phone, but all the things for a rooted samsung are completely different compared to an htc. Thank you for all your help guys. I have learned my lesson now

Good luck. I hope the overnight battery pull helps or that the jtag folks can get you up and running.

For the overnight battery pull, when I try to boot it, should I try to put it into download mode? Or just plain boot? Thanks again
