Do you put your phone on a back pocket?

No man, actually I dont think this is a hardware problem, because the patron of the grain change, sometimes there are more, sometimes is a green color, or a purple color.
Edit: other reason that I dont think this is a hardware problem is because this issue it had already hapenned to me other times and always fix itself automatically with the time, but this time I dont think so.

Broken Kaiser or it's a software issue? please help! I can't start my phone

Htc tytn II.
It happened already once before two weeks and today again and i can't start my kaiser. First time i manage to start it somehow i don't even know how and i thought it won't happen again. When i push a start button only green color light appears on it, and nothing on screen. like it didn't start at all.
After that i can't do anything except soft reset which only shut down phone and green light gone then. Or take battery out! so i tryed everything later and now can't even start my phone anyhow!
I flashed rom in past and have some of dutty's rom in there
Please help me and tell me what is wrong with my phone and how to repair this problem?
now i can't even get green light. now is completely dead. I am worried if i send it at service with warranty that they will see i have no official rom (i'm on dutty's)

Flash it back to stock, all the details are in the wiki, you just have to read. Then you can warranty it.

If it is dead and won't start how are they going to find out you don't have a stock rom?
It is not like they have a bunch of brilliant guys sitting around HTC miraculously reviving dead phones. They through it in the dead phone pile and use it for parts.
Could be a battery issue (highly unlikely as I havent really heard of this happening ever) but still, its possible. So, if you have a replacement battery try it out. Also, has it been water damaged, have you dropped it multiple times or has something hit it hard? These things could also brick a tilt, something like that happened to my friend when a door slammed his wizard.
I doubt its a software issue, a software issue would still allow it to turn on.

now i tryed again in the morning and green light on phone again works. but only it!
So it is now a battery issue then ?!
doesn't help anything else again. didn't had any hard hit in it. i was yesterday at Prodigy music concert so maybe there get some hit but it should not be anything seriously.. For the first time it didn't get any hit.. It was rainy here yesterday and i had it in my pocket, but first time when this happened it wasn't rainy, than it was on hard sunny day and for the first time i thought it was because of sun! Now was quite rainy and wet day...
hm. i have news now here, when i leave it on green light started for a longer period, i get those multiple lines colors on screen i see. it's approx. 10 colors lines... and it stays for a 10 sec. approx. and after that it shuts down itself! And now again i cant even get green color. Disaster!

I suggest trying another battery as was said before. Or it can be also broken screen or something.

it's not broken screen because first time i somehow manage to start it and it works normal for 2 weeks.. so it must be a battery...
i will try with other battery later from friends kaiser

ok, let us know if that worked.
i tried with friends battery and it's not a battery problem. With his battery same problem, and when i put in my battery in his phone it works normal...
looks like I'll need to go to htc service using warranty... i hope it won't be some problem with them because i have dutty's rom
argh... not good!
now i got phone call from servicer who manage to turn on phone. And he saw in there dutty's rom, not official and my warranty now won't worth
now everything what he will do with phone i will need to pay by my own money.
Now he started phone and he says that he will return it to official rom and see will phone work then normal. If not he said he should change whole mother board to fix this problem which is really huge expense. He told me price almost same as new kaiser!!! terrible!
disaster, now i heard with service and the phone is not working well even with official rom now. I don't know what to do! He said he need to change motherboard and the cost for that is like new phone! Terrible. So, to be honest, this rom flashing is total mistake because could easy loose phone just like i do.
i would like to sell it but don't know how now because he don't work properly!

That's the risk you take when flashing a non OEM rom. If the rom your using isn't worth that risk, then don't flash it.
I bet the rom you were using didn't cause the problem either.

The problem can be or can not be caused by rom flashing. It could be just some hardware fault which has nothing to do with rom flashing.

i agree. i also don't thing it's because of rom flashing. probably some hardware failure...
but problem is when i can't start phone i can't change official rom offcourse
anyone know how much new motherboard cost and can i get it online somehow? here in croatia is not easy to find this because very few this phones are available... same with parts of this phone

Hello. I'm experiencing the same issue, which I detailed a lot here. So far, not a single answer. But the more I Google, the more I find people with the same issue, but still, a bit rare...
http://forum.xda-developers.com/showthread.php?p=35018530#post35018530
Additional symptoms before this unusable state: after a phone call, when removing the phone from your ear, screen stays black. You have to press any button you can to finally switch the screen on again.
Crazy !!
If you read my post, you'll see that I can use the phone as long as it's plugged to a power source...

[Q] Why did my Ace goes mad when I decided to turn EDGE network instead 3G (HSDPA) ?

It also happens when I'm not in a range of 3G connection. I though that there is a mistake in rom but it does in every single rom i tried. Should I try it in the Stock rom or what ?
Symptoms are...my phone decide to click on whatever in middle row of a screen or it holds a specific place of a screen and sometimes it becomes uncontrollable (I have a fight of clicking f. eg. The phone taps on Calc when I'm trying to open Settings and it opens calc.)

I never had such a problem with my Ace. I have pretty much tried all the roms here. Can you check this with a stock rom? If you are still experiencing this problem even in the stock rom, then it must a hardware problem. Do post the result. Hope I Helped

Yeah I will try in a few days...I wonder that it could be hardware problem because I changed a digitizer two months ago and I could damage something
Same problem is there on my friend's Micromax A45 on stock firmware(only while charging)

Well, where did he bought the phone ? From second-hand (I mean from another user) or brand-new from a shop ? He could try fix it on his own but I don't recommend it with non-popular brands they are difficult to repair (I know I had some chinese phones) or try his luck at service center or if he still has a warranty he could reclaim it.

How long have you had this problem, have you done any customizing that requires root? Sounds like a hardware defect to me.
Buy it on ebay

Yeah sadly you probably got a lemon. Two things to try
1 factory reset
2 odin
If both result in the same problem you have a hardware problem and need to contact the seller. If he refuses to refund or send you a new unit tell him you will report him to eBay and if you used PayPal tell him you will report him to them as well. If he still refuses do what you threatened to do. This might sound bad but when you report to PayPal tell them you were scammed and you should get your money back, if he doesn't help you he gets what is coming to him. Of corse you should go back to the page and make sure he didn't state this as a known issue because if he did you can't do anything.

Well I figure factory reset then odin if the problem continues. Odin is pretty safe but there is risk of bricking every time you use it, just takes a communication error while flashing the bootloader to perma brick. Good luck, hope it all works out in the end.

You could also contact samsung. They will probably fix it for free + shipping but you will be without your s6 for up to 3 weeks so you would need a backup phone.

Question Mi 11 Ultra Dead screen

Hello all,
I've been using my MI 11 ultra with the Xiaomi.eu latest stable version for months and never had any issue. Today, I was making a videocall on Whatsapp, and after hanging up the phone, the screen just turned black and never came back.
I tried to reboot on fastbook/recovery, but seems like the screen is just dead. Things that I tried.
- Plug in the phone charger (nothing happens)
- Force restart phone by holding the power button (It makes a little vibration like it's rebooting, but nothing happens after this)
- If I connect my phone to my laptop, it detects the phone as MTP, but I can't do anything with it.
- I tried to list device through ADB, but I doesn't appear in the list.
I have no clue what to do, at the moment it died, I wasn't doing anything special, I thought It would be because of the heat, but the phone wasn't hot.
It's really weird. Is there anything else I can do? Am I missing something?
Thank you in advance!
I think it's time to take your phone to service center...

Agreed!!!
has anyone sent the phone back to china for screen repair during the warranty period? Wonder how the process works.
Warranty with Eu. rom?! highly doubtful.
if you can fastboot your device, i'd suggest that you install original rom. (DONT LOCK BOOTLOADER). then jump to fastboot again and lock your bootloader. then send it for warranty. I don't think you'll need the screen to do that.
dont worry about device access and boot inside, doesnt matter.
Thank you all for the answers.
I stil have my last breath of hope, I found someone who had a similar issue with an Mi 11 => https://xiaomi.eu/community/threads/black-screen-on-mi-11-ultra.63498/
I wasn't expecting it for this phone, you never expect this kind of weird issue from a 1k phone hahaha. It never happened to me and I've been flashing my Xiaomi devices since 2010
I'll try one last time, the back screen is not responding neither and as far as i know, they have different video controllers and since my computer can recognize it, I still have some hope.
This issue got me on vacation in the middle of the rain forest, and as you can imagen, internet here goes really slow.
I'm trying to download all the stuff that I need and once i have it, I'll try to restore my phone. I'll update you all with the results
Thanks in advance!
that would be great because if one of us should have the same problem then he can look in here and help himself
Hey all,
After fastboot, nothing changed unfortunately, I think I'll need to send it to warranty.
thank you all for the help

I had similar problems on my samsung galaxy a12. I flashed older fimware and the screen would just not work, it would be pitch black 24/7 no matter what I have done. I had to blindly enter in to odin_mode and flash new fimware. Similar thing is for you, try blindly booting in to fastboot or what ever you and flash the orginal ROM and don't use EU one because they probably wount accept it with in the warranty. AND UNDER NO CONDITION, DO NOT RE-LOCK THE BOOTLOADER
Hello all,
I have fresh, happy and weird update!
I was decided to send my phone to service center, I was just waiting to come back to Spain from my vacation, meantime, my phone was between my clothes since my last update.
Today I took it again while I was packing my things and voila! Screen is working again
My guess is that after taking a heavy rain, it got wet somehow (I say this because it supposed to be waterproof) and this caused the screen issue (3 days after the my rainy day).
Leaving the phone between my clothes, it my helped to dry out any water that could have leaked inside and phone is working again.
So, what I learned from this experience, never trust the waterproof certificate, hahahha.
I think once I'm back home, I'll put the phone on the water and try make the issue happen again, then send it to the SAT.
Thank you all!

Warranty doesn't cover water damage as far as I know
You might be safer not trying to repeat the experiment
