phone dead ;(

Have been running various cooked WM6 builds for weeks now on M700 and put on the latest AX3L WM6 build last week. Worked well. Then on Saturday noticed it was running very slow. Turned it off and didnt use it Sunday. Came to it Monday morning and it wont turn on. Nothing happens. Occasionaly i get the HTC boot screen but nothing else.
Tried hard reset - nothing.
Tried forcing it into bootloader screen (power+camera+reset) - nothing.
Does anyone else have any help as my phone is toast?
Thanks

Is your battery empty ?? (stupid question but we never know)
Otherwise, if it's not empty, try to remove it for a while and put it back into your device. If it doesn't work ... I don't know.
The buttons light up quickly and the power green light comes on for about 1 second and then goes out but the screen remains black

Try to reload your battery or change it maybe.
OK followed this post http://forum.xda-developers.com/showthread.php?t=308691 and it seems to have worked. Although not sure what I was doing

G1 Black screen, Cannot get to bootloader

Hey, I have been given a phone off a friend to fix but it wont turn on. Booting normally, I get a vibration and then the backlight comes on but i cannot see anything. When i try to boot into the bootloader by holding the camera button and powering it on, the backlight comes on but nothing else. I cannot see the bootloader. Under both circumstances, I cannot turn the phone off. I have to pull the battery to turn it off.
Does anyone have any suggestions about a possible fix? Thanks
Havie you tried send when trying to enter bootloader? If it resets then you can still get to bootloader. If not, your friend has soft bricked and only way is to JTAG which takes strong hardware knowledge and steady hands.

ok im having the exact same problem. actually i thought it was a battery problem so i spent 77$ on a 3700 mAh new batter i guess tripple life... and got it yesterday booted gave same problems. black screen where T-Mobile should be yet the rom loads with scribble screen meaning u see part but it looks like the pixels are messed up. so actually decided to resort to what someone told me a Factory Reset so Pressing Camera + Power i got a Black Backlight screen yet wont show... and I cant turn it off without Taking out the Battery this has become a issue after installing cyanogen 5.0.7 T5... since then i Re-rom'd to superbad 1.2.5 same problem screen scribbles and stops im thinking did I fry it i dont even know how to google my problem because its pretty unique it isnt a battery issue its something in the hardware ... or am I wrong please send us some feedback... ill keep this thread in mind
Sorry, what do you mean by 'send'. I am a complete noob when it comes to G1's. I have worked out i can shut off the phone by holding call + menu + end but thats it. I still cannot see anything at all on the screen. I still only get a vibration on boot. How would I know if the boot has been sucessful but i simply cannot see?
Could the flex ribbon cable be nackered?

[Q] Help!!! Grainy green screen With lines during boot up

It started about 30mins ago, was on a call which the screen locks off when u on a call like stand by, but when ending the call the screen would turn on back no matter what. anyways i took out the battery thinking maybe the roms just buggy or the battery dead since it was on low. puttin back the battery the phone wouldnt turn on, took it out and tried again same result.
so i put it on charged nothing, gave it about 2mins charge it came on, but the boot screen with the X just had some green pixel dots all over and horizontal lines for about 3 secs then back to normal, but the phone wont boot pass that.
took out the batteries again, back in then try boot into fastboot or bootloader but nothing, just the boot screen, then the rom booted after waiting, took longer than normal. so i turned it off and try the bootloader or fastboot but it wont load just the rom, so i restarted to recovery mode from the rom it worked, turn off and try bootloader or fastloader mode they worked, now it seems all working fine, also my touchscreen is responding perfectly and the rom loading ok.
but anytime i boot the phone the bootscreen has the green pixels and lines just the same. im abit worried as i dont want things getting worse, is there anyway to fix this, is it some virus? could i just flush everything and start over???
any help would be greatful, thanks.

You guys think updating my radio from 4.06 to probably 5.08?
Almost similar with few different colors but I dropped my n1. It took me almost a day to see that the LCD was broken. Turn off the phone or screen and look in sunlight. They really were hard to notice and I showed to 4 different peoples whom all failed to notice until I showed them. Hope yours is just a minor software problem.
well i just check its not broken and it didnt fall from me so im guessing its software but im wondering if it can fix but i dont wanna flash my phone and things get worse or even brick my phone, so im asking before i try anything more.

Screen stays black! Audio and touch are responding.

Hi all,
I woke up this morning and my note's screen hasn't been working. I didn't drop it or spill anything on it, it just doesn't turn on. I know the phone is on because i can hear and see the capacitive buttons light up when i touch them. Does this mean i need to replace the Super AMOLED/digitizer unit?
The only thing i can see is the white Samsung logo (very faintly at that) when its booting up.
I found a site that sells replacement units but i don't want to buy it unless i have to.
I need some advice.

Hey thanks for the reply. But i my phone is not even rooted. it was working fine last night.. the only thing i did different was i didn't charge it over night. So i thought at first it was a battery issue. I'm so sad... lol
sounds like the backlight is burnt out... unfortunately this is not something that can be replaced itself... the digitizer/lcd will need replaced. now is the fun part... either find the country your note is made for and mail it to the warranty dept, or have it fixed by a reputable repair shop out of warranty...
No need to have root, to go to stock recovery
Just switch off device, keep holding vol up + Home + Power
when light turns, release power button, but keep holding other two.
If you able to enter in recovery, N can read on screen, means screen is intact.
wipe cache, wipe data
N still error remains, flash Stock ROM

[Q] Samsung Galaxy S GT-I9000 won't work if not plugged on external power source

Hi guys,
The following problem has taken me litterally DAYS of reading XDA, trying everything I could, but still no solution. Googling and searching this forum didn't help either, and it's totally weird.
It's a Samsung Galaxy S GT-I9000, on which were installed, almost two years ago, the ClockWorkMod recovery, Darky's ROM, Froyo, and everything was fine for months. Then, one day, out of nowhere, it switched off, without notice. Impossible to switch it on again! I remembered having seen some strange battery behavior few days before, like falling from 80% to 30% with no reason, so I thought of a battery issue. I plugged it for a full night. In the morning, I was able to boot it, but not easily, and all apps were crashing: during boot, or when launched manually. Yes, all I tried were crashing! Then, the phone became fully not bootable: press the power button, the screen shows "Samsung GT-I9000", then switches off...
I ordered a new battery: same result.
A guy from a phone repair store told me to plug the phone, and keep the power button down for 2 minutes: after this, I could reboot the phone, and thus, wipe data (factory reset). But it didn't help.
After "playing" a bit with it, I realized that the problem is:
the phone won't boot if an external source of power is not connected (as said above, white text shows, then the phone "dies")
if started with power cord/usb, the phone will work fine, all the time
if started with power cord/usb, and the external power source removed once the phone is booted, the phone will work fine, UNTIL the screen goes black for power saving mode or by pressing pwoer button, after which, within seconds, you can't open the phone anymore. I mean: if you press the start/power button immediately after the screen goes black, the screen goes on again, and the phone is ok. If you wait for few seconds, it's over, you can't do anything, and have to reboot the phone. This said, the phone doesn't vibrate, so I suppose it's not really off. But then... what is this state??
I really tried my best: updated to GB2.3.6, bricked my phone trying to re-install the CWM and having a bootloop, installed and used Odin and Heimdall, reverted to stock kernel, etc, etc, etc.
I feel sorry to bother you guys, I was really convinced that with the incredibly huge amount of data, how-tos, explanations, etc. I would manage to get rid of this, but this problem, though I don't really think it's hardware (but maybe it is?) stayed across so many kernels, roms, etc. that it's killing me!
For the record:
Model number: GT-I9000
Micro-software (?): 2.3.6
Baseband: I9000XXJW4
Kernel: 2.6.35.7-I9000XWJW7-CL1125830 [email protected] #2 (problem was the same with [email protected] #2)
Version number: GINGERBREAD.XXJW4
Any help would be greatly appreciated, considering that a wireless phone that needs to be wired is a little bit of an issue... :laugh:
Thanks in advance !

That's a very strange problem... let's try something, remove the battery, sim card and sd card and hold the power button for 1-2 minutes, btw when the screen is off, is really the phone off or just the screen? did you try to make a call to your phone when the screen is off?

Hi timberman thanks for the answer!
You're very right: I totally forgot to say that what initially allowed me to restart my phone "regularly" was this procedure of pressing the power button for 2 minutes (hint given by a man from a repair shop). Before this, I couldn't (kind of a bootloop).
It's a very good question! I don't think the phone is really off in fact, because there isn't this vibration saying the phone turned off... Let me try to call it!
F..k! I was redirected right away to the voicemail... so... phone was off
I'm starting to think it's an harware issue... I reinstalled lots of ROMs, kernel, etc. Same ****...
Any idea?

Hi! Answering is already nice
I tried the button pressed for 2 minutes without battery: didn't change anything.
I tried playing a sound: MAN, YOU'RE A GENIUS!!! Launching the music, then forcing the screen off with power button lets the music play, and OF COURSE, I can reactivate the screen by pressing the home button. The screen goes off normally again after few seconds, but the music is still playing, etc. So, as long as the music goes, the bug doesn't happen!
Other hints:
For some time already, when I was removing the phone from my ear after a call, quite often, the screen was staying off, and I had to press a lot of buttons to have it on again, and be able to close the call
The moment where it crashes when booting without power is the very INSTANT where the initial white text (Samsung Galaxy S) goes brighter. So, if you unplug the power cord just after this, the boot ends normally. In summary, something happens at boot just after screen brightness changes which is the same thing happening when the screen goes off for power saving. All this, only when no external power is plugged.
Hehe, we (you) are making progress

Hi again, it seems like your phone is unable to exit the deep sleep mode or something like that so, let`s try another thing, in ICS or JB there´s an option in the developer option settings that unfortunately is not present in gingerbread roms, so, you can try to switch to a ICS/JB rom and go to settings-developer options and disable the "PM sleep mode" let`s see what happens then

I tried to install ICS, with a GREAT tutorial found here: http://forum.xda-developers.com/showthread.php?t=1494493 Sadly, the phone reboots after installing the ICS kernel, and then doesn't work anymore, I had to reinstall the Gingerbread (I tried twice).
Last news: I let the phone play music (sound muted!!) for about 12 or 18h: all was fine! So I decided to pause the music, and see what happens. Boom ((c) Steve Jobs)!! The screen went black, and phone was "dead". I was expecting this, so no panick, I put back my SIM card, my SD card, and tried to reboot, with power cord plugged: it boots until the screen shows the small loader animation, then the empty battery image, but then goes black again, instead of showing the charging battery!! Download mode is still available, so I'll try to reflash the kernel, say.
It's like if each time screen was put black, phone was dying.
I can't stress enough how I appreciate your help: even if we can't save my phone, it's very pleasant to be able to TRY things. Thanks man!! :good:
Update: I reinstalled all... and it's not, even with power cord in, going further than the "Samsung Galaxy S" white text. The moment this picture disappears from screen, phone is dead. For good this time ?

Hi! No, I didn't, I used Odin. But now, I can't try anything anymore The only "results" I can get from this phone are:
- enter download mode and update from Odin (maybe from Heimdall, too, but I didn't check)
- reboot until the first moment the screen goes black, after which, the phone becomes fully unresponsive
