Hi Guys!
I do have a big problem with my Defy.
I updated the CM9 onto the newest version and had to activate my google-acc. I didnt finish the smartphone registration and put my Defy to the side. Today morning the battery was empty and I reloaded the battery. After that I turned the device on but the only thing it shows is a black screen with stripes (even in cwm and bootloader). Does anyone know how to fix my Defy??? The Defy boots completely but the screen remains crappy ;(
Please help me!!!
With best regards

Edit1: (27.12. 1421): New day, same problem ;( Still found nothing helpful...
Update: (27.12. 1736): Flashed a new fixed sbf with RSD Lite. Still the same problem. Could it be a hardware problem??? LCD-Display broken or stuff like that? Didnt throw the phone through the room like others (^^);
Update2: (29.12. 0801): Error still remains... Is their anyone who had the same problem or who can help me? Do I have to replace my Defy? Might there be problems with Amazon (warranty) because of root and stuff like that?
Update3: (30.12. 2217): Now trying the tip by cengiran:

hi there,
i have the same issue but not due to CM9 installation but due to hardware issue. judging by your writing, this has nothing to do with software and so hopefully this helps.
My screen is also black at boot with some part of it are stripes (and some bad white and blue square w/ noise) and looks like a broken LCD monitor.
This is due to hardware malfunction (probably your battery went bad) in my defy the battery have some water damage and somehow it screws up the voltage regulator or the grounding part, but does boot with the correct screen using some techniques on every boot.
Try this solutions:
1. completely discharge your battery, take it off, hold the phone power button for 30 seconds to make sure every power stored in phone is out. Put the battery back on and connect the charger while the phone is still off. DO NOT turn the phone on. Your screen will look all mess up when showing the green battery, wait until 3hours and take a look at your screen again. In my case, the screen showing the the battery charging image is clear again after i did this. - this is to make sure that your screen is actually okay. Try turning your phone now and see...if its still bad then go to step 2.
2. turn phone off, open the battery case. Connect phone to charger again without turning it on. The phone will do its regular boot up until showing you the battery icon again. when the battery icon is there, PULL the BATTERY out of the phone (the charger cable is still connected to the phone). the phone will reboot itself with the correct screen usually, if it doesnt boot itself, quickly pull charger cable and reconect it again (with the battery still detached from your phone).
mind you if you get to the okay screen, this will not boot your phone, this will bring you as far to the battery icon with a question mark (we know for sure is just battery issue now). regardless screen is okay or not, proceed to step 3.
3. turn off phone, battery out of the phone, and press the power button for 30 seconds. release power button and re-insert battery and boot. (usually still bad but this is to ground any left voltage in there). after it boots (with the bad screen, if the screen is okay then proceed to using your phone like usual) before the LED lights blinks (the 2nd.init lights) pull out battery, press the power button for 2 seconds, re- insert, and boot. repeat this as necessary until it boots with an okay screen.
tips:
battery empty is for step 1 only, steps 2 and 3 needs power form the battery.
You can actually go to step 3 if you wishes, but my experience is by using step 2, it will talke less retry until i boot with the okay screen (i need to do this everytime i restart the phone mind you, so its a daily thing) .
the LAST tip: there no rules of thumb on how many retries it needs, if you have been retrying for 20 minutes on step 3 with no avail, revert back to step 1 or 2 and retry step 3. If this is sill fails, then you might need to consider purchasing a new battery, or take it for a repair!
Im still waiting for my new battery, but now it only takes me 5-6 tries before it boots correctly, in the apst it took me 15 minutes of constantly retrying so be patient, but still need to set a line when to give up!
Hope this helps and good luck
how does it go?
to completely discharge your battery is tricky...and actually not recommended because i heard our kind of battery should never went completely gone, it can mess up the battery capacity. i suggested it because thays what i did and in this case, battery cost much less then actual repair,,call it collateral if you will.
heres what i did to completly discharge it...after the phonse turned off automatically due to battery running out, it still have around 2% in it so reboot and enter 2ndinit/boot loader. let it stay there until the phone turned off on its own again. in 2nd init, the phone wont turn off screen so it will continue using whatever is left in the battery. keep n mind that even at very small amount of juice left, this process can takes up 2hrs or more.

Hi cengiran,
thank you very much for your help. I will try this immediately. The only problem I do have that my battery doesn't want to go empty XD
There are so many people who want their battery to last as long as possible and now I want to get it empty a quick as possible XD Irony
Since 26th December 1004 pm my Defy runs with one single battery charge XD I think thats a pretty good battery life for a smartphone ;D
If your tips don't work I will sent it back to Amazon and hopefully they send me a new one or repair my old one.
Thanks again and I will post if your method works.
With best regards

P.S. Amazing that this thread is the 1st Google search result for this problem XD

Thanks a lot, a mix of these two works for me !
My problem arise after a month that I switched off defy for replacing it with a new smartphone (Xiaomi M2S).
I removed battery to force it to switch off, because I couldn't see anything.
I replaced the battery, I connected the phone to charger and after ten seconds (more or less) I removed the battery.
At this point I can see the Motorola logo. I've re-inserted the battery and it shows that it is at 97%.
For sure, the lcd is working
Hi, so my phone decided to stop working all of a sudden.
I was just doing things on my pc when I heard my phone rebooting, after I had recenly plugged it in.
It's running the latest stock ROM and not rooted. When I try switch it on it shows the Samsung Logo and on some occations some pixels create a fuzzy area underneath the logo text and at the bottom of the screen, it then switches off and after a while tries to boot again. When I try charge the phone it goes to the battery icon with the loading circle but nothing moves and yet again some of the pixles of the battery icon become distorted and then it switches off and tries again(also it vibrates twice before showing the battery icon). I can boot into Dowload mode and my PC recognises the phone(as well as odin) but I can't boot into recovery, or Safe Mode for that matter. I can remove the battery when in dowload mode and the phone remains on but I need the battery inserted to start up anything. I've only had my phone for two months now. Maybe I could be moisture from my shower earlier, I'll leave my phone in a bowl of rice overnight to see if that does anything.
Please try help me fix my problem. I've been looking for a solution all night.
Also due to me being overseas I can't format my phone as I'll lose my WhatsApp validation and all the pictures I've taken so far will be lost.
Thanks in advance.
It's not a software problem so you don't need to format.
My guess would be that you need a new battery.

The battery isn't even swollen though?
I just tried starting up the phone by turning it on, then plugging in the cable and hitting the battery out but it still didn't boot.
Unfortunately I'm far away from a big city so I can't get another battery to test it to be absolutely sure though.
Update:
I just tried booting it again and it got to the other Samsung screen where the LED is Blue and the Logo flashes blue behind it(Only got here once, hasn't gotten this far again yet). I left it for a bit but it just got stuck there and there was the same distorted pixels like in any other type of screen I get to also the logo stopped flashing when I tapped the screen and pressed the home button(this is when the distorted pictures started again).
Here is an attached Image of the flickering part of the screen. It gets stuck on this screen and flickers at the bottom and just underneath the Logo and eventually turns off.
No one know the problem?

It's a hardware failure. Let's hope it's your battery even though it's not swollen.

I tried a new battery today and it had exactly the same problems
So by some miracle it booted all the way to the lock screen and then rebooted from there right back to the lock screen again and I unlocked it and the home screen was fine and the phone seemed to function for a few seconds then it restarted and then got stuck at the Samsung logo again, I did manage to see that there was 17% Battery left so It has enough power to boot it. So I dunno what the hell could be causing it. It's such a weird problem I have no idea of how to fix it(within the warranty that is). I forgot to mention that the screen has 3 stress fracture cracks on the screen so somehow I think it is bending in my pocket, so that might be a reason why it's acting so weirdly.
I also noticed that if I leave the battery out for a decent amount of time and try boot the phone up it boots up for about 20 seconds and then reboots again into a bootloop again. Also the battery percentage is at 0% apon boot, by this stage I've plugged it into my PC to try pull files off of it(Which I managed to get some files off).
Hello everyone! I will try to explain my problem as briefly as i can. Last Friday i was replacing headphone jack, and before this i put away battery. After replacing i sticked battery back to phone and tried to turn it on, but caught bootloop. I put away battery again, and sticked it back, and after that wasn't able to turn my device on with turn on/off button, just with turn on/turn off and volume down buttons. Now i can turn it on normally, but there is a huger issue with battery. It drains faster now, sometimes phone can turn off with no reason, and Nova Battery Tester shows sometimes +10c and after just 10 seconds temperature can become +60. Is it an issue with battery or what? Everything working good except battery.
SO Sunday morning I wake up and my phone has been on charge all night, its 100%, I unplug the phone and about 10 minutes later its very hot and at around 60% battery. So to stop this I go to turn it off and start seeing these red "bubbles" under the screen like water but its the LEDs turning red. I have never dropped the phone or put it under water. Its a hot day as it is and about 5 hours later I turn the phone back on and its fine for around 15 minutes watching youtube videos, it then starts flashing black, like the whole screen shuts off for half a second and comes back, still sound playing, about 5 minutes later the phone starts glitching out and the pixels on the right hand side start turning red (no link) like so. Then the phone starts jumping between that and this ( no link ) which happened for around a minute and since then the phone screen is just black and doesnt display anything but the phone is still active and had feedback on the screen such as touch vibrations. Really want to know whats happened and why if anyone can help
Probably a hardware defect that will be covered under warranty. But possibly a software problem that's causing the cpu and gpu to run really hot. You can try booting into safe mode to see if that makes a difference:
Shut the phone off and let it cool down.
Boot into safe mode: https://www.google.com/search?q=gal...rome..69i57.3932j0j7&sourceid=chrome&ie=UTF-8
Use the phone for a while, and see if the problem reoccurs. (Your 3rd party apps will be disabled, so you won't be able to use them, but you can do other things.)
If this seems to solve the problem, delete any recently installed apps, or factory reset the phone, and see if the problem stays resolved. If so, add your apps back in a few at a time, so if the problem reoccurs you'll have an idea what caused it.
If none of this solves the issue, it's a hardware problem.
My wife had EXACT same problem. Backup everything while you can as my wife's phone died few hours later. (no display at ALL - digitizer was working fine though - so could shut down, etc). Symptom also was that when you reboot, it will display the boot up screen just fine, but as soon as all white screen was able to display, display will just die, etc. Pressing power button repeatedly would eventually turn on the screen but color would be off and simmering, etc.
My S4 keeps rebooting and I think it's a hardware issue but I do not know exactly which part might be the problem. It did slip out of my hand and dropped on my desk (not that hard) but it did not show these symptoms until a few days later so I'm not exactly sure if the drop is the cause of this issue.
It does not necessarily reboot at the Samsung boot screen all the time. It sometimes reboots at the Samsung logo screen or after 1-2 mins at the home screen. It has also frozen at the Download mode screen, so I don't think it's an OS issue or a bad app.
I've already tried a different battery (new one I just bought recently) and I don't think it's a Power button issue because as I initially thought it could be problem with the Power button so I had removed it and had planned to solder a new one. Without a power button, it still freezes/reboots. I did notice sometimes after it has frozen, when I try to charge it nothing happens (no red light) but once I pull the battery out and put it back in, it charges again. Also sometimes when it freezes, I have lines on the screen, but once I take out the battery and restart, it's ok.
I would hazard a guess that the LCD or digitizer might be the problem (but I don't to waste the money if it ends not being that)? The only reason why I say this, is because I managed to get to the home screen and enabled USB mode (screen was off after) and it did not reboot or freeze for more than 5 minutes (longest so far) until turned on the screen and seconds later it rebooted.
Can anyone advise whether it is likely the LCD that is the problem? I plan to get a new phone soon but wouldn't mind fixing this if the parts are fairly cheap.
Any help would be greatly appreciated!
Answer me this: If your computer freezes, would you suspect the screen? I mean, the screen's sole purpose is to display stuff. So why would the screen cause the computer to freeze?
Same story, different device.
Your issue will most probably require a motherboard replacement, as I don't think you can find the faulty parts separately. I suspect either CPU or GPU.
