[Defy General] shady_lanem:
I flashed to every other possible roms i could think of but to no avail. My flash still remain very weak. It's not totally dead but near to useless to say the least
[Defy General] reinsen:
in the german android forum there were far more ppl with these kind of issues.

and ive not heard of users of other roms with this problem. doesnt look like a coincidence.

as we dont know of the complete constellation of this problem to occur, based on the knowledge we have, the chinese sbf is a factor to consider.

and that someone thinks to have solved a hardwareproblem with software... i guess its more likely that he never had the hardware issue to begin with. maybe another problem with similar symptomes.
[Defy General] Step666:
Well, that's kinda my point, it's not all that clear what the problem is or whether there are multiple similar problems.
[Defy General] Darkcaptain:
I think the Chinese ROM is something problem, I put the ROM China and since then FlashLED burned, I've tried all available ROMs and all possible evidence and have not gotten anything ...

And so I have more than 1 month...

Sorry for my english.
[Defy General] reinsen:
as i said. there might be different causes for the LED to get damaged but the china rom seems to be a factor in every case.
[Defy General] rznag:
On the german forum there are even less people with this problem. They all reference to xda. But the hype about this "problem" is much bigger on the german forum, but no one can confirm it really. I`ve written also on the german forum about this problem. Most of the people on the german forum complain about a yellowish oder greenish led, but the number of burned leds can be counted with maximum 5 fingers. I think it`s 2 or 3.

On this forum + android-hilfe there are just 5-10 people who have really killed their led (not confirmed, some had no problem anymore after a flash or wipe), and no one can really confirm that it`s because of the chinarom.

On the german forum was just said it`s the chinarom and as evidence was said the different names for defy. MB525 vs. ME525. But in my eyes this is no evidence.

I`m sorry to say, but in my eyes this are only single bad luck. If the rom would really kill leds, then there would be hundreds of people with burned leds.
[Defy General] cocus:
Hey, to check if you have burned the LED, just simple look at it. If you se any black-dot in the yellow thing in the center of the LED, then you have fried your led. (Im electronic technician). That could be made by over-current (if you get more voltage, then the current will be great, and the led just could support it).

If not, then it might be a ROM problem (means diffrent Drivers, or other gpio used for that). If another gpio was used, then you have to check if that pin is marked as OUT. But I don't think that is your case.

Anyway, to do a quick test, on a Terminal emulator, put the following:

(I think you'll need to be root)

echo 1 > /sys/class/leds/torch-flash/flash_light

That should turn on the Defy flash light. At least, that path is working on my stock ROM.

To turn off (in case it worked), just do:

echo 0 > /sys/class/leds/torch-flash/flash_light

As I've tested, you might have to restart the phone if the flash light starts to "flash".
[Defy General] Darkcaptain:
The black dot is visible always? Or have to turn the flashlight to see the black spot?

I tried the command in a terminal emulator in my case has not been turned on.

THX and sorry for my english.
[Defy General] cocus:
Yep, the Dark dot means something is burnt inside the LED.

The script gives you any error? Or just it didn't work?
[Defy General] Darkcaptain:
I speak spanish (you are from Argentina).

La pregunta es, que si se ha de tener activada la luz/Flash para ver el punto negro o si el punto negro es siempre visible? (aunque no esté activada la luz/linterna)?

No me dio ningún error, simplemente no se encendió el Flash / did not show any error, just did not work the flash.

En mi caso, el Flash no funciona, pero cuando lo enciendo, se puede apreciar una mini-luz muy muy pequeña, por debajo del 1 % de potencia que tenía al principio / In my case, the Flash does not work, but when I run it, you can see a mini-light very very small, less than 1% of power was at first

Thank you

EDIT: In my defy, I see no black spot .. but maybe I should compare it with another Defy to appreciate the difference. There is a picture/photo to see the difference?
[Defy General] cocus:
Ok, entonces tu led no esta quemado. El punto negro se tiene que ver siempre. Pero si decis que tenes algun tipo de luz en algun momento, me suena a algun problema interno. No estoy seguro de como esta alimentado el LED: puede ser alimentado por un pin de GPIO, o por un regulador. Si es el caso del regulador, puede que haya un conflicto con el driver (baseband o lo que sea, creo). En este caso se puede quemar el led si el regulador puede entregar mas voltaje de lo apropiado.

Si es un pin GPIO, el LED no se puede quemar jamaz, ya que este pin solo puede prenderse o apagarse, con voltajes fijos.

Ok, then your LED is not burnt. The black dot has to be there forever. But if you say that you got some kind of light at some point, it sounds like some internal problem. I'm not sure how this fed into the LED can be powered by a GPIO pin, or a regulator. If the regulator is the case, there may be a conflict with the driver (baseband or whatever, I think). In this case you can burn the LED if the voltage regulator can deliver more than appropriate.

If a GPIO pin, the LED can not be burned, because this pin can only be turned on or off, with fixed voltages.
[Defy General] Darkcaptain:
The only thing I appreciate is a dark dot (light brown almost yellow) ...
[Defy General] cocus:
Take a photo with macro-zoom. Or grab a lens and put in front of some camera to get more "zoom".

BTW, somebody could take a photo of a working-led Defy?
[Defy General] lackyking:
LED has not found traces of burning.

Can use a suitable size to replace the broken one?
[Defy General] lackyking:
I'm so sorry!

How to run this test? What's a Terminal emulator?
[Defy General] cocus:
I dont think that. Those LEDs are SMD (surface mounting devices). They're harder to get soldered because of the size, and the machinery. Of course you can try, you might get a good result. But first try what I suggest, if you're going to open your mobile:

If you have a normal LED (3mm or 5mm), you can test touching the same pins in both LEDs and see if any LED brights up. (Take note that the leds have 2 pins, and they work in 1 combination, not in every position). But this process is hard as hell, as you have to dissasemble the entire mobile and void your warranty.

Find it on the Market: "Terminal Emulator". Or run it via "adb shell". But I think, the access to those paths is restricted to Root only. (as I see, you've changed your firmware, so I believe that you have rooted it)
[Defy General] Darkcaptain:
I have only one compact camera, I can not make good photos ... that's all I could do, the last photo is in a dark room with the flash on.
[Defy General] cocus:
Well, thats not definetively a burned led. In the first photo it might be... but in the other ones, definetively its not burnt.

Here we have a problem with software, or another part of hardware damaged. As nobody knowns exactly how its the defy schematics, I can't assure what kind of problem is that.

Take the phone to your company and take a look if you have good look with the warranty.
[Defy General] lackyking:
Has already been fixed by replacing the LED problem.

[Defy General] shady_lanem:
Can someone translate that to english please! :eek:
[Defy General] reinsen:
is it so hard to use google? :(
[Defy General] psicodelico:
My flash is not burn. I can turn it on and off using a app for that but when i go take the picture the flash color is blue/green.
[Defy General] jeffokada81:
Use Google chrome, it will ask you to translate or do it automatically for you.
[Defy General] Darkcaptain:
Someone who does not work the Flash, has tested the new ROM China?

I want to try, but do not know if it works with the MB525 and the current ROM I have (Froyo Orange PL)
[Defy General] chaihg:
Since it is not even a year since this phone released, why dont all of you who have a burnt LED give back your device and claim it under warranty?.

You would get a new device right. Its easy to restore whatever rom you came from.
[Defy General] Zaben:
I was going through build.prop for some thing else and noticed these settings on my 3.4.2-145 build.

ro.media.capture.flashIntensity=41

ro.media.capture.torchIntensity=25

What are these set to for the Chinese ROM?
[Defy General] Jt612:
So there is no solution for the green/weak flash light problem?
[Defy General] Darkcaptain:
I not think , my phone has been sent to the Motorola Technical Service by the famous problem of the speaker (in calls) and also by the flash camera.

In 15 days say it will be repaired, I will write here.

Sorry for my english.
[Defy General] Jt612:
will it damage my phoen further trying the lightfix? to see if it fixes the gren flash problem?
[Defy General] dogo2:
Yesterday I looked my LED under a microscope and unfortunately there were some brown spots on it. I compared it to a working LED and as you may think it hadn't any brown spots... So I guess it is really burnt :(

I installed the original firmware and sent it back to be repaired. I'm waiting only for an official update now :rolleyes:
[Defy General] edition-:
Us that are on "undowngradable" ROM's i guess we will have to wait for an official 2.2 and then send to repair :\
[Defy General] dogo2:
I'm not sure why everybody speaks of undowngreadable... I have installed this ROM and then flashed back the original 2.21.0 (DE, AT, CH) - MotoBlur sbf from here with RSDLite. Everything went ok.

I have to say I'm not an expert. I cannot promise this will work on your phone too.
[Defy General] shady_lanem:
Bummer :( My flashlight is near to useless. Can't even lights up an inch away. Well, I'm getting Atrix in few days then sending this back to warranty
[Defy General] slashvanyoung:
My LED flash died as well and yes, I did mess with the earlier Chinese Froyo ROMs so that might have caused the issue.

Before the flash completely died, I noticed it going out of sync with the camera.

Fortunately, I didn't have to wait for weeks to get my repaired Defy back. They got me a replacement within a day.
[Defy General] edition-:
Jboogie's ROMs are all downgradable :), i got passed 2.51 and all the froyo builds, can't get back :\
[Defy General] fabianowerner:
My flashlight was OK on Pays Rom 4.1 but i figured that it was weak, reflashed original Eclair 2.1 and now its very weak, barely can see it on video camera, and the photo camera it flashes but only a weak light that cant light up nothing. And when i tried to turn it on using an app (Flashlighter) it went very very weak and only a small brown point turned on. Did i break my flashlight?
[Defy General] naenee:
The LED light was not designed to be used as anything other than a camera flash. Using it as a flashlight may well have broken it.

Hm. That said, the video recording feature has a button to toggle the LED, which would contradict my above statement :)
[Defy General] fabianowerner:
my led now is gone, cant turn it on using videocamera, and its really weak with green light at the end, using photo camera.
[Defy General] walter79:
I sent in my defy with broken LED to Motorola.

"Their unit had an unofficial firmware. We would like to point out that this situation leads to an exclusion of warranty. Your device, we have repaired after consultation with Motorola with 100% participation grace. We recommend future only authorized software updates to play on your device."

:D
[Defy General] farsight73:
Does anyone with original firmware 2.1(never been flashed any rom) having flash burned as well?

Just want to narrow down if it really is all the way came down to motorola own hardware issue..

Will receiving my defy this week. Just want to make sure if it indeed an internal hardware issue all along.
[Defy General] danimagrin:
Did you send it with unofficial firmware or not? How did they discover it?? Curious! :D
[Defy General] Andrew-droid:
Hey Walter,

How did they fix it? Was it a software or hardware problem?

I had a weaker flashlight but used advanced camera app with torch led function or something like it a few times and it got strong again as before using a Tesla Led flashlight app.

Just used Camera app a few times, going in and out until it came back well.

Now I have a firmware with Pay's ROM and led goes weak on flashlight app and then strong again on video recording or camera apps, no problems anymore on this rom and firmware.

Cheers!

Andrew
[Defy General] walter79:

Just sent mine today, waited for the official french froyo ROM since i bought it in france, lets see if they repair it or if a get a new one xD

I was on chinese and sense rom too
[Defy General] fabianowerner:
Will send mine tomorrow cos i got the damned earspeaker problem, i will tell them about the flashlight, i restored eclair and made an official upgrade to froyo, lets see what i will get. Unrooted and uninstalled cwm. Hope they fix everything.

[Defy General] fabianowerner:
My Defy came back from Motorola Brazil and they fixed both earpiece problem and flashlight problem (caused by flashing chinese releases several times) and now im booting into MIUI, lets go back to the modding world again.
[Defy General] alanthemanofchicago:
Depends how damaged it is. If the voltage is too high, and the light is "fried", then no. But if there is some kind of protection that prevents the flash from coming on when voltage is too high, it might be saveable.
[Defy General] psicodelico:
I sent my Defy to Motorola Services today!! I got the problem with earspeaker and I took advantage and talked about the LED:)

15 days without my phone :(
[Defy General] fabianowerner:
im pretty sure that they will fix the flashlight cos they did on mine when i sent the device to fix the earspeaker. i think they replaced the mainboard but they kept my green lense :(

Found a very detailed video on youtube, which shows how open it....seems easy to swap out
[Defy General] nameite:
Ok just to follow up on my last post

I swapped out the flash light

Now everytime i switch the phone on, it gives a blast of flashlight for a split second, then gone again.

And it doesnt work once i get into CM7.1, either flashlight or camera

I'm guesssing something is still shorting the flashlight, so it goes off to stop it from burning each time its switched on?

Anyone have any idea where or how the flashlight is controlled physically/electronically?
[Defy General] nameite:
Ok guess no one can help me.

Anyways, after replacing the flashlight, now the flash light works when taking pics.

Originally it use to light up upon switching on the phone, now it seems to go on every now and then, every few minute to every 2 seconds.

The battery is draining very quickly and my gf is nagging and complaining like a biach.

Isnt any electrican online that can check where and how the flash is turned on hardware-wise? Maybe I can replace a cap or something on the board.
[Defy General] Motivateme:
Maybe different telephony module for CDMA use, not flshlight...

[Defy General] sbashwin:
I recently flashed the chinese rom to downgrade my defy plus. Later I noticed that my led flash wasnt glowing brightly instead it was very dim. Then I flashed sbf and didn't notice any improvement. Since my defy is still in the warranty period, I will claim for warranty. So I guess you will face a similar problem if you flash the chinese rom :crying:
[Defy General] TJKV:
More info about this situation:

1.Camera/LED was never used after the Froyo BL6 SBF was flashed, until it was rooted and a custom ROM (CM9) was installed.

2. After rooting, 2ndinit-ing, and flashing CM9, the boot logo still had Chinese text in it.

3. However many people seemed to have downgraded to Froyo using the same chinese SBF without problems, so this issue seems random.
[Defy General] Krassu$:
i heard its mb due to some other hardware specs in china with different voltage or something for the flash:/
[Defy General] TJKV:
Over current rather than voltage, according to the above person. Either way, using a "safe" /system (cm9) also caused the problem, so it probably originates from the version 6 signed froyo kernel from the Chinese rom...
[Defy General] bufa:
hello I have a problem, I cant install any custom rom. Only 2.2.2 via sfb

defy green lense

I think I might have installed some custom rom with GB Kernel. But I'm not sure.

The problem started when I tried to go from CM10 to Pikachu, Aroma Installer finished but with an error message about the "Bootimg" (or somthing like that, the message told me to reinstall. I did, but then bootloop started).

After trying all CM roms (bootloop), I flashed Nordic 2.2.2 SFB via RDSLite.

Now froyo 2.2.2 works fine, I can root, instal bootmenu, etc, but when I go to custom recovery and install a custom rom (CM7, CM9, CM10) It goes back too bootloop :(

What could I be doing wrong?
[Defy General] Steveletack:

[Nook Color General] adunofaiur:
Long story short (and in a list!)

I rooted my 1.1 nook color with autonooter 3.0

I could not launch YouTube

I downloaded the .apk but did not know how to do adb

Thus I erased and derigestered my nook

I reactivated it

Then I did the 8 reboots

Nook color gave an error at the default homescreen.

I tried to derigister but failed

I removed the autonooter card andput Honeycomb on it.

Honeycomb works fine, but with stock no slide to unlock icon appears.

Help? I would really like stock to work...

Sorry for butchering simple instructions.
[Nook Color General] RickOSidhe:
When you boot the NC w/o the uSD, you state that you're getting an error message at the home screen.

I had something very similar happen to me after I interrupted Autonooter3. If the error message is something along the lines of "The Nook has encountered a system error that requires a restart", then try the following process. It should get rid of it and put you back to stock.
