Fixing the light ambient sensor?

Hello all, I've got a rather complicated problem I was hoping that someone here would be able to help me with, before I have to resort to getting a replacement phone.
I while back my Hero stopped working after some water damages. I managed to fixed the thing by cleaning it with rubbing alcohol, it turned on and everything, but the brightness setting would cause the screen to flickers out of control, or just go off altogether, until I decrease the brightness to the lowest setting.
Ok, this still works out for me, unfortunately due to some carelessness, I broke the connector on the screen. Of course, the next best thing to do was to buy another screen from ebay. I was hoping that somehow that this would fix the brightness issue as well, but of course it didn't. The phone boots and runs just fine once I lower the brightness all the way, except for one problem: I get no bootscreen.
When turning on the phone, I can feel it turn on because it buzzes once, but I will see nothing on the screen until it gets to the lockscreen. I assume that this has something to do with the sensor keeping the screen off because the system hasn't boot completely to get the brightness setting down? Anyways, I was happy with it able to boot, so I went on to do my normal rooting thing. Everything went fine except I get no data connection after rooting Cyanogen/AOSP, so I used ROM Manager to install the OTA update, and after the phone restarted, it never comes back on again...
I have a feeling that it's giving me some sort of error, I just can't see it because I don't get to see the boot process. I can't boot into recovery either because I can't see that screen either. My only guess is that the light sensor has something to do with this.
Does anyone have any idea how I can go about to fix it if this is at all possible? Is there any way I can revert it back to factory without having the need to see the recovery screen? Or maybe if someone has an idea on how I can do this blind...
I know, crazy problem, but I'm really stuck here, and looks like I won't have a phone for the next few days...
I appreciate any help in advance.

Ouch.... it is alot!
So I hope ur due very soon for a new phone... sometimes u can see old heros for $30 or $40.... but until then...
I think ur best bet is the RUU via usb from HTC since u can't see certain screens and with this method it's just plug and wait Cuz ur computer will tell when it's finished.
The RUU zip file requires that u can load into hboot screen so unless u can, then that's no good.
Good luck

Thanks! I'm not due for a discount for another month, and my contract doesn't expire for another 2 months after that...
Can you tell me how I can get to the hboot screen? I think I can get to the Recovery Screen by holding [Home]+[Power], although I just can't see it to make any selection/change. Is there a specific button combination to get to the hboot?

Hboot:
From off...
Lower Volume button + power button at the same time

Basically I just hit [+] twice and let the software does its thing. Thank you!

You've got a hard brick, seems to be happening to many lately. Get a replacement or get the motherboard changed under warranty.

Was this brick caused by the S-Off and restore? or just randomly?

Apparently, it's random. Mine bricked like this too. They'll replace/repair it under warranty, they can't know about unlocked bootloader or s-off after a hard brick.

Well, mash the thanks button all you want . I'm having a hard time keeping my anger with htc down. My phone was repaired 5 times within 5 months, and yet had problems, so they replaced it and gave me a new phone which was defective and now they're gonna replace that phone too.. Damn, I feel like killing them

When I was trying to do MID change, part of the process puts the phone in QHUSB_DLOAD mode, I ended up getting out of it by shining a bright light on it a few times with it plugged into the computer and having a device manager open so I can see any changes. It took a few tries, but it got detected eventually.
Try that as well.

Hi, Thanks for the reply!! Im willing to try ANYTHING...the light was directed at the proximity sensors? and were u holding the power button? because if i hold the power button it goes in and out of the qhsusb mode but if i dont it just stays there

Correct that's what was happening to me too. Yes shine the light on the sensor. I will suggest keep trying. You don't have much to lose, unfortunately

Sigh...still no luck..and i dont think there are any htc repair centers in m country

UPDATE: Tried the bright light trick, tried holding all button combinations separately...tried everything..left the phone plugged into the pc, left it in the wall, still no red light but now when i connect it to the PC the device manager list just refreshes. No more qhsusb_dload it just refreshes over and over...i saw on a thread that some guy left his plugged in for 4 days and it came back on. Whats the chance of that happening for me?

If you have a QHUSB_DLOAD device then there is nothing to do. Your motherboard must be replaced.

[Q] can't boot

Hello xda, I just want to ask what did happen to my G1, I'm just using it ordinarily everyday but a few days ago something happen, it cannot boot but only led lights flashing, I can't even reach the recovery or bootloader, is this a hardbrick or something? I'm using a froyo rom I forgot what rom it was and I also using the right radio and SPL combo required for that but I don't know what happen, It just can't boot. Help please.

Is it just blue led? If so then yes its bricked and you need JTAG, if not you may be OK, but as to what happened that's hard to say
May be a battery issue but with LEDs flashing less likely, try to get a PC to recognize, try charging over night and testing with PC again, try booting without SD or sim, try any button combo you can

no not blue

hello demkantor, the led light wan not blue it was like a pink? or something like that, I've tried home+power button no use, camera+power button still no use, really can't boot only led flash, that's all, is there any way I could save my G1? please help, thanks

Can you get a PC to recognize it and are you able to get a new battery?

I dunno the problem

Hello again dem, since my phone can't boot, my laptop can't recognize it, and I'm confident enough to say that my bat. don't have any problem, I do have a universal charger and my battery are charging using it, one strange thing, I also have a cabled charger for my G1 which has a led light as well, I've tried charging it using that and the led light of my charger are blinking which means it is charging but the led light of my G1 was not blinking, I really don't know what happened to my G1, I hope you could give me some help, any way I tried to search for what JTAG is, but I think I can't do it since I don't have any ideas when regards to the hardware aspect of android, I'm even a noob on software aspect of adroid devices.
P.S.
I forgot to say this, sometimes another strange thing happen on my G1, whenever I try some button combo to reach either recovery or bootloader, my buttons and keyboards have lights but my screen is totally blocked out.

Sorry to say but I'm thinking your motherboard is shot. Send me a pm when you get a min. May be able to help you out

hi again dem, I don't think its on the battery, call me crazy or anything but still remember N70? I have one, though their battery differs in size yet their gold energy conductor or whatever they call it is just the same. Since the battery of the G1 are easily drained I need to have two battery but since I'm from Philippines I have hard time looking for battery of my G1 that's the reason why I used my N70 battery on it as a backup whenever my G1 runs out of its juice. Before I can successfully use my N70 battery ( I just place a paper or anything on its side and lower portion to make the fit right) but since the problem on my G1 occurred even my N70 battery are useless and unusable because it still don't boot. I know my problem is a weird one but I'm looking for a way to recover it without modifying or replacing its hardware. Don't have money for it. Hope you could help me with this. thanks.
P.S.
I never run any problem before using my N70 phone, its maybe because they have the same voltage which 3.7 the thing is their capacity. For you to believe me I attached here the photo of my G1

Xperia Z confusing problems, please Help me.

Hello !
A few weeks ago my XZ fell down and the display (glass,lcd,touch) was broken so i had to fix it. I decided to fix it by myself, i bought a display and started to do it on my own. Everything went fine. After I finished i wanted to charge my phone and the red (bright) led was on. I knew, that this was the symbol for charging so i was happy and waited a few minutes. But my phone never went on, there was no Sony Logo, no battery logo, nothing, no vibration. I decided to take another look into my phone, and checked if anything wasn't right reconnected, but everything was correctly. With still no success i thought, the battery was dead (because it lay down about 4 weeks with no power) and ordered a new battery. I inserted the battery, but all i got was this damn constant red light. (at the beginning its a bright light and then switches to a darker light).
I read about 5 Million forums and got in contact with flashing my device. First i tried it with the Companion (no success), later with flashtool (no success).
All i have to say is that, i dont even now if my screen is working, i easily come in fastboot/flashmode and i'm definitly at the end of my possibilities. I need someone's help, and if you say my phone is completely damaged, then please say, so i can stop working on this matter and sell it!
Thank you very much, and sorry for the long read.

Maybe motherboard got damaged or check the connections

I checked again my inner phone and, okay im new in fixing phones, but it seems to me that nothing got damaged, everything looks fine, the flex bands don't look different as they are shown in the videos. The connections are 100 % connected. But i have to admit: New battery -> not working, check connections -> all are stable , PC companion repair -> nothing. After all i think i destroyed something but i cant figure out what. On Monday i'll go to a repair shop and let them check what's the issue. If somebody has another idea, please let me know, i will try to repair it then.

Hey thanks for answering! As i mentioned in my starting post, my PC detects my phone without any problem. I also used PC Companion to repair my phone. So i dont think it's a software matter. Also Flashtool detects my phone, i could even install a new software.
But i gave my phone today to a repair shop, they'll analyse the problem... for 20€.
I'll tell you what exactly is damaged in a few days if somenone has the same problem like me.

I destroyed the Display Connector. Sold my phone for around 40 euro. -.-

SAD DAY, is my Note finally DEAD? :(

Hi Guys,
So this morning, I woke up to find my phone had rebooted overnight. Not surprised by this, as it often happens randomly from time to time. This time however it was stuck on the Samsung splash screen, black screen with white writing, saying N7000 blah blah....
So I rebooted the phone, and it was still stuck on the N7000 splash screen. I left it like this whilst I drove to work, and it was still like it.
I took the battery out, and left it for a little while and put it back in, but NOTHING. black / blank screen... I left it on charge on and off through out the day, as I was trying to fix another phone issue (someone elses at work...)
Anyway, got back to mine, and still nothing. Still nothing booting or displaying on screen now, just blank / black screen. As our phones don't have LED notification light, can't tell if there's life there or not. The [Open Windows] and [Back] buttons don't light up or anything.
I've read about the famous "Samsung, Black Screen of Death" which appears to affect many Galaxy branded devices, S1 - S5, Note 1 - 4, and some other models, higher up without removable batteries.
They all seems to post positive remarks, getting their phones back from the dead, by holding power button down for 1x minute and leaving the battery out to drain phone of residual? power.... I've tried this, and still no life yet. They say it may not work first time... I've tried it a few times.
Do I keep going, or is it DEAD DEAD now?? Anyone else had this? Has it worked for you guys or not??
So gutted, loved this phone...
Thanks, Lister

:crying:Still DEAD:crying:

Have you tried using Kies to restore the OS? Or download the OS file from Sammobile and install it manually using Odin.

Hi @iceepyon,
Thank you so much for replying, I appreciate that... :good:
Sadly though, I think my Note is a little beyond that stage... It doesn't even turn on, with or without battery/mains power. I think either the eMMC chip is toast, or some other hardware failure now.
All these Black Screen of Deaths for Samsung video's appear not to apply to my device, and think my device is actually just a paperweight now. Gonna try one more time to bring it back from the dead, with a JIG and see if I can repair it that way... Otherwise, it will be going to the great Silicon Heaven, in the sky.....
Thanks again... Lister

Best of luck to you. If the eMMC chip is indeed toast then you would have to purchase a replacement motherboard. It is very hard to find a N910C motherboard.
