Not sure if this is in the right place but here goes
So I woke up this morning to my phone not turning on past the bootup screen, checked the battery, thats not the issue. A quick google search led me to sudden death syndrome where the mobo just dies. I want to replace it. Thing is, my phone has already been flashed from sprint to boost. I am wondering if by replacing the mobo, do I lose this flash? I noticed when looking for new motherboards on ebay etc that they are listed as bad/good ESN, does this matter for me seeing as my phone had already been flashed and all I am replacing is the mobo? Or will this upgrade necessitate a new flash.
Thanks in advance

I couldn't turn on wifi anymore, the switch stayed greyed out and 1 out of ten times i could switch it on it kept giving the message "turning on wifi". The phone got really hot on the backside next to the camera lens so i send it for repair (Dynafix - Netherlands) now my gnex is repaired and they did a "boardswap" (?) this means that they replaced the whole motherboard? Is this a good thing? An second question, could the wifi module be defect because of flashing roms?
Thanks very much

Yes they likely replaced the whole motherboard.
No, roms should not harm your wifi module.
Overclocking and excess heat might be able to though.
Flashing ROMs normally doesn't do anything to the motherboard, itself, but if flashing the wrong radios, or installing the wrong drivers could cause such a problem...
But as long as the phone is working, all is good, don't you think?
If you ask me, I do it this way:
(This is an example only). Phone broke, phone bootloops, with stock ROM, flashing a new ROM won't help, I phone my carrier, I get a replacement, if I don't like the device anymore, I phone again, say the device I got is also defect, I get a new phone of my choice, for free...
I have had to do this twice (hTC 7 pro and Samsung Galaxy S II, yet the GS II was really defect, so was the 7 pro), now I've got a GNexus, it won't boot, doesn't show up, at all, neither as OMAP, or anything. I could probably JTAG it, but as I regret buying the phone, because I miss the button, and I don't want to risk the same think happening, I phoned up my carrier, I'm getting a GS 3 on Friday...
(I will still help with GNex problems, though)
Thanks for your answers, very clear! By reading this i think i broke it myself because for a while i had an older radio with a ics 4.0.4 rom but i can't recall the exact time wifi died on me. Well.... my gnex is fixed for free (warrenty) a little more reading before flashing Thanks again for the answers!

What? installing the wrong drivers on your computer has nothing to do with the motherboard on your phone. My HTC drivers don't affect my nexus, why would they? Flashing a radio won't hurt the motherboard either. It may disable the wifi but it won't physically break the motherboard.
Hey guys,
My GN's screen randomly just wont work. The system boots up and everything (I can tell from vibrations and notification light). Its unlocked/rooted and running a 4.2 rom. I went to verizon this morning and theyre shipping me out a new one this week. My question is would I be able to swap out the motherboard so I can avoid having to completely reset my phone etc, and avoid any worries regarding them finding out that the phone is unlocked and rooted, I dont think I can unroot it without use of the screen. So can I swap out the motherboard or is the motherboard married to that individual MEID number? Any help would be great, thanks in advance:good:
anyone?
nevermind just gonna swap the screens
Good night xda,
I am once again turning to the forum for help,this time for my older SGS3. While I upgraded to the S4,I gave my ATT s3 to my sister. I've had the phone since it was released. It does not have any physical or water damage.
Initially,I had a custom rom on it and all was well. When I gave it to my sister she did not like the rom so I flashed the stock ATT rom back on it. She used the phone for about 6 months after that with no issue,but about a month ago she complained that the phone sometime shut down randomly with no warning. The screen just went black completely,sometimes when she was not using it at all. I did witness this a few times while looking at it so I was pretty puzzled with what could cause that.
Now yesterday,she called me because the phone was completely dead. It shut down randomly again but she was not able to power it up again this time. I investigated,tried different batteries and plugged it in the pc and had to concur. It does not react at all. Black LCD,no battery logo,no even the power up vibration so I cannot access download mode. I understand the phone is now hard bricked.
I am extremely surprised the phone bricked over a certain period while I was not even flashing it. I did not flash it in the past 3 months. How could it get brick with no flash ?
I tried the SD Card image file from this thread http://forum.xda-developers.com/showthread.php?t=2345860 but it did not work. However,I do not have a 16GB micro sd like the thread suggest using,so I will try again tomorrow after I buy one.
Any ideas regarding this situation ? Is the s3 dead completely ? Would a jtag service work ? Or the sd card method ?
Thanks.

is it possible that the LCD went bad?? when you plug it into charge does it react (lcd or vibrate?) I would also suggest trying out a known battery. could be that if it is the original battery that it is so dead that I got "spikey" and finaly just died.
hope it is that simple

If she wasn't trying to flash anything, doesn't sound like a brick which, to my understanding, results from software failures. The procedure posted in the thread applies when you are trying to recover from a brick caused by firmware failure from attempting to flash the wrong bootloader so I'd be doubtful if it would help you here. This could be a specific hardware failure which is not unheard of with equipment like this. Also sounds like it gave warning of the gradual failure. When you plug it into a charging outlet, does it show any sign of life - a light or vibration? If it's an LCD failure, it probably wouldn't affect charging or recognition by your PC. If there is no sign of life at all even with different batteries, you may want to try a professional repair service as I presume exercising the warranty is not an option in view of the firmware history.
Hi,
Thanks for the replies.
I did try different batteries. The phone does not vibrate or react at all even when plugged in which does not suggest an LCD failure.
I guess you are right,it must be a hardware failure. I'm quite suprised,I thought these phones were well buit and resistant.Oh well.
She's getting a Nexus 5 now.
Thanks for the help !
I am in need of help! My phone is dead. Here's the rundown
AT&T Samsung Galaxy Note II (i317)
Used on the Straight Talk Network
Running the latest Unofficial CM12, Lollipop 5.01 for the last week and loved every bit of it. No problems.
I cracked my screen in July and never got it fixed. The cracks spread and I was planning on getting it fixed, but haven't yet. I dropped it two days ago and then the screen wouldn't come back on. The buttons lit up and it would even ring when called. So I thought my screen was finally gone and started looking for a replacement. I took the battery out because I didn't want it ringing without the ability to answer it. Yesterday I put the fully charged battery in and attempted to turn the phone back on. It will not come back on and I think it's more than just the screen now.
Red LED blinks. Half of the screen seems like it is turning on, but then it all goes dark again. Will not enter Download or Recovery. I've been reading and thinking this is more of a hardware issue than software. I've flashed dozens of Roms with only minor issues here and there. I haven't had any issue with Lollipop and can't see it being related, although I could really be wrong.
My question is, is my phone dead? Do I need a new motherboard, along with the screen I was already gonna replace? If that's the case, I will just replace the phone and start over, unless anyone has free parts they want to donate, LOL! Seriously, just looking for input and suggestions.
Thanks

There's pretty much nothing to say, but I guess I will.
You can't get to download mode, can't get to recovery mode, you can't see the screen......
If you're looking for a second opinion to say you're f*cked, then consider this it.
If you could get to download mode or recovery mode, it has a chance. But you still have hardware issues like the screen to replace. Which is not fun.
Possible yes. But unless you really know what you're doing and careful as hell, you take the chance of hosing something else up. Like ripping a ribbon cable or yanking a soldered wire out....
I tried replacing a Motorola Atrix screen. The result of that was me buying an Atrix 2.
Unless you are emotionally attached to this phone, bury it.
If not,

I did some quick searches and doesn't appear to be any kind souls out there with spare parts. You may want to try CraigList or something like that.
Good luck to you

Hey, Thanks man! That's what I needed to hear. I have been flashing Roms since I had a Sprint PPC 6700 and I have enough experience to now I was f#@$ed, but I really needed to hear it from someone else. Someone with developer experience. A screen assembly and motherboard cost more than another phone on ebay or Swappa. Welp, back to the drawing board. Anyone got a note 2 they wanna sell cheap?

No worries.
Feb 3 I'll be on 2 years with my Note 2. Longest I've kept one. Only have one smallish crack on the lower left corner.
With everything I've done to it I'm amazed it's still working.
Hey everyone... I was using my phone as usual when suddenly it blue screened and died on me. Like dieded died. I've been soft bricked before but this was bad. It wouldn't on after taking out the battery, charging, different batteries (anker)
Left it for a while tried again, nothing. Like not even the boot up animation. Now, the phone had been acting up for the past 2 days. Random reboots every few hours and it even blue screened the day b4 but came back as usual. I was just considering a new rom cos i had been on this one a while so i thought maybe it was just time for a new flash when all this happened. Full disclosure im rooted xposed on Dirty Unicorns Marshmallow. Also not sure if this is relevant but i had recently begun using new batteries from anker for the past 2 months
That's the only new thing i did to my phone. I use my phone to just below 5%, off then pop a new 100% battery in. I hadn't charged my phone my cable since.
I went to a repair shop immediately and they tried hooking it up directly to a positive negative power source but they said it wasnt registering at all, so im thinking this is serious.. I Googled around and best i could find was that this maybe a motherboard issue. The only solution ive found online (https://forum.xda-developers.com/lg-g3/help/lg-g3-d855-blue-screen-death-t3380844) were those saying i need to bake\heat the motherboard?? At first i thought it was a troll but im desperate and not sure anymore
Is that a legit solution and if not, what is...? Please guys i can't afford a new phone for at least another year. Thanks in advance.
