[Q] No backlight

[ctennenh]

I've been running ViperXL (Bulletprrof 1.3 kernel) just fine fine for a few weeks. It's been nearly flawless. Just now, though, the backlight went out and nothing I do seems to bring it back on. I've rebooted, plugged into AC, and tried booting into recovery. In the sunlight I can see just enough to know the device is on. I've managed to get into settings, which thankfully has a white background, and verified that brightness is at max.

There is no backlight even through the reboot process.

When you reboot the phone, does the boot image (Default HTC Screen) also have no backlight? Or in recovery is there a backlight? If not, it's a hardware failure. Screen would need to be replaced. If the backlight comes on when in recovery or during first boot image, then it's something software related which is easier to fix.

There's no backlight anywhere. I know it's not kernel since I was able to fastboot flash the default kernel for ViperXL over USB.
If I bought this through AT&T less than a year ago does anyone know if it's under warranty? I'd hate to pay to get the screen replaced. I'd rather try to get it back to stock and take it in.

That's assuming, of course, someone can point me to instructions for getting back to stock! I've looked but haven't seen any in the forum.

It's hardware. You need a new screen. You would need to s-off if you're not already and then run the appropriate ruu for your carrier. I believe at&t will warrant it np.

S-off directions are stickied in original android dev section and ruu's can be found in the resource compilation thread linked in my signature.
Make sure to download an executable Ile and not a zip. Easier to return to stock with exe

Thanks a ton. I'm already S-Off. I spoke with customer service and they're going to send me a replacement device (same model, though I asked if it was possible to change). Should I be using the one labeled [ruu] [stock] att 2.20 ota? There are a few whose names look like what I might want.

No you'll want one that is ruu and not ota. Doesn't matter what version so long as it's at&t. The filename will end with exe

Ok, so like [STOCK] AT&T RUU_Evita_UL_Cingular_US-1.85.502 ? And the RUU will wipe anything that's not stock, right? Thanks.

It will return your phone to stock but your bootloader will still be unlocked and you will still have s-off. You can spoof it like it's never been unlocked and return it to s-on though I doubt that would be worth the trouble.

I see. So you don't think they'd bother digging too deeply to notice it's s-off and unlocked? I'll run the RUU tonight and check in later.
I really appreciate your help this evening.

Since it's a hardware issue, I doubt they'll care to dig That far into it. From what I see on here AT&T is pretty lenient about unlocked phones, especially when it's a hardware issue.

I'm having difficulty running the RUU. I've rebooted and connected my device to my computer and run the RUU utility. It says it can't find the device and to check the connection. I can't see the screen well enough to turn debug mode on or off on the device. What can I do to run the RUU?

 

[exad]

Try running while in bootloader/fastboot?

That did it, thanks. Now to wait until the sun is bright enough out today to wipe the SD card through settings.
I'm going to miss being rooted.
