So my phone running CM 10.1, turned off randomly. So I tried to reboot but kept getting stuck on the Samsung boot logo. I rebooted to CWM recovery mode, wiped cache and dalvik and rebooted which I thought would fix the problem somehow which it did. However, when it said "Android upgrading, optimizing apps", my phone lost battery (thought the phone charger was plugged in). When I plugged it in the outlet properly this time, I got through the battery charging logo. But when I tried turning it on afterwards, nothing. The phone doesn't respond when I tried to turn it on. Took the battery off, placed it back and when I plug it into the outlet, there is no more battery charging logo and I can no longer reboot. How can I fix this? Somehow, the phone might be trying to continue to turn on but is not responding when I try to actually turn it on. When I plug the charger, take off the battery, unplug and replug charger, the battery charging led lights up for 5 minutes (which is weird cause I disabled the indicator led when charging in the system settings). I allowed it to be plugged in to the charger overnight and when I checked this morning, nothing. No symptoms that it was charging; no heat on the phone. Is not being able to charge a symptom of a bricked phone. I have yet to try using another battery.
If you can't power on or get to DL mode or anything and none of the buttons respond it could be a hard brick

I checked at a Sprint store and the device they have couldn't make a reading off my battery meaning it was most likely dead. I'm gonna try with a new battery and hopefully my phone isn't actually bricked.
Best of luck sir

Ah, just my luck. A Sprint representative placed another battery on it (I didn't see it though) and told me that the phone still won't turn on and told me he can open and check the phone if I pay. So, I think it is hard bricked. :crying: How did I brick it? Ugh..I'm just dismayed on the information and data I lost. What are my options? I heard Mobiletechvideos.com does a jtag brick repair with an option for internal sd card recovery?

I had to get a JTAG when I flashed a wrong kernel. Although when I got it back I had lost nothing still had custom ROM and recovery and all my data and apps were there. If its hard bricked its because something happened to the bootloader

How can I know if I need a JTAG or my phone need an eMMC Chip Repair Replacement. What if my phone experienced a sudden death. If it's the latter, it's expensive as the website lists it for $150, almost the price of a new two-year contract phone.
Oh well, I'll send it in anyways for a jtag. Hopefully they can fix it.

Its kind if hard to say if this was a brick or not. Usually sudden death is out of the blue, as far as I know the only way to achieve a hard brick is flashing a bad or international zip file
What's 150$ though? The emmc or the jtag

I just experienced a similar problem as OP, and I didn't even flash a new ROM or international ROM. Since January, I've been using the ICS version of FreeGS3, stock kernel.
http://forum.xda-developers.com/showthread.php?t=1748818
I haven't flashed any new ROM's since January 2013 and have not experienced any problems until now.
This morning, however, when I woke up, I discovered that my Sprint S3 was stuck on the "Samsung Galaxy S III" logo. I pulled the battery and powered up, and it got stuck on the same logo again. I repeated this process several times and the same thing happened. After looking at some XDA threads, I went into recovery and decided to wipe cache and dalvik to see if that fixed anything. Again, the phone booted up and got stuck on the "Samsung Galaxy S III" logo again.
However, when I tried to boot into recovery again, I wasn't able to do so. I tried several times without any luck. I decided to see if I could put the phone into download mode. I did, and it was successful. I didn't do anything just yet because I needed to research more fixes before seeing what needed to be done. I put the phone into download mode several times without doing anything, but then later, the phone itself wouldn't power on.
No matter what combination of buttons I pressed, the phone simply wouldn't power on. I even tried other batteries which I knew were fully charged. When I put the phone on the charger or plug it into my PC, no charging lights light up. However, when I pull the battery an plug the phone into my PC, the charging light lights up and it the PC seems to try to install drivers. However, despite the charging light lighting up with the battery pulled, but phone plugged into the PC, I still can't get the phone to power on at all and therefore can't get into recovery or download mode.
It's similar to the problem the person in this video is having where he uses a jig to get back into download mode.
http://youtu.be/FdrdWqaXUBE
I have a jig on the way, so hopefully that helps fix my problems, but I don't really understand how the phone got bricked in the first place; First it was soft bricked when it got stuck on the "Samsung Galaxy S III" logo, but I was still able to get into recovery and download mode. Then, it was hard bricked when it wouldn't even power on to get into recovery or download mode. Did it get hard bricked because I went into download mode too many times? What might have caused it to be soft bricked. The thread for my ROM is now closed, so I don't know where else to ask these questions. I'll update you as I try to fix this problem. Any other suggestions are welcome.
Your device is not bricked your device doesn't even have a software failure. What you are describing is SDS sudden death syndrome.
Your power button has failed. It's defective and the manufacturer knows it. It fails at the motherboard not the physical button itself. Since you where able to get into download mode I suggest you return the device to stock unrooted, do a triangle away function and take it to Sprint. They usually repair of exchange it for you.
Have a great day!

Hmm...I suggest you are talking about the other poster since I am not able to power it on at all (Recovery nor Download mode). I don't have insurance nor have warranty, I don't think Sprint would be able to fix it without me paying an incredibly huge amount. I was hoping that my data would be recovered but now that you mention the possibility of sudden death syndrome, there's no way I can recover the data if it is. A sudden death syndrome would require a replacement of the eMMC which is rather costly.

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 !
Last week,before going to sleep, I put my s3 phone to charge before going to class. When i woke up in the morning i knew something was wrong because my alarm never rang.
Because i live in india now, I first called samsung and they told me I would have to pay 70$ just to ship it to texas center and then have to pay whatever the cost is to fix the problem.
Naturally, I took it to a mobile repair shop down the road. They first said my phone had some boot problem. After a week they said nothing could be done and that the motherboard is fried.
Here are the problems.. When i woke up, the phone was off and the charging light wasnt even showing. I kept trying to turn thr phone on and it tuened on once all the way to the samsung logo and sound and then shut off again. After that, it hasnt turned on since. Boot menu doesnr work. Download menu also doesnt work.
It doesnt turn on but the charging light shows uo when i insert thr charging cable.
What do you guys think? What should i do? Is my motherboard really fried? Should i try to find a new motherboard on amazon and try setting it up myself? I dont think my warranty is still active with at&t if that makes any difference.
Looking forward to any help,thanks.
Plug into a computer and check device manager. If it says qhsusb_dload or something similar it may just be bricked. If so try the debrick method in this section. Worth a shot before spending money on it.

After I plug into the computer..nothing happens.
Ill try again after i get home.
The phone is rooted. Though i havnt updated it in a very long time.
Also i should mention that sometimes the red charging light comes on and sometimes it doesnt. Also when i connected it to a different computer it showed a message rhat something failed to download.
Which charging adapter did you use? Was it the stock samsung adapter or an aftermarket one?
so after plugging in the phone to the computer, I tried to look for anything in the device manager, however have come up empty handed.
So, its safe to assume, its not bricked (as that is semi-reversible).
And that the phone is most likely motherboard fried...which sucks and means I have to get a new phone.
Is there anyway to extract the information from internal storage? like documents and pdfs and possibly notes? Or is that option not available aswell?
I am thinking it is a hardware failure at this point. I would say to check the USB port as those to tend to get damaged sometimes, but you took it to a shop already and they should've noticed it if that were the case. These devices are getting old though, and I've been seeing more and more hw failures lately, so considering all that you said in the op, what the shop told you and what has been discussed here I am thinking that will be the most likely conclusion.
As for getting your data back, I kind of doubt it will be possible. If a shop can't get to it with special equipment and programs, you won't be able to do much more on your own. If its very important/valuable data, you could always try a professional data recovery service, but you're probably going to pay a good bit for that.
I am sorry that this happened and that I can't be any better help to you. Good luck with whatever you decide to do. And feel free to ask for a second opinion. Its always possible I could've overlooked something.

Have you tried a fully charged different battery. You're USB port could be bad not allowing your battery to charge or connect to the computer. If this is the case, your battery didn't charge and went dead during the night and it also may not be getting power from the computer when plugged in. With another battery you might power up and retrieve your data.
S3 motherboard replacement
Hi guys,
I hope somebody here can be of any help. my i9300 (s3) got fried while charging last month. while i was planning to dispose the phone. due i cannot use it anymore and i bought one for good which currently in use, my co-worker just broke the screen of His phone too (s3), fortunately,he agreed to give me his and ask a friend of mine to replaced the motherboard on my s3 with the one from my co-workers phone. the replacement proceeded successfully but upon testing any sim card does not work. it display it has a coverage bar signal, but the notification on top says no sim card.
anybody who would share a thought about what will be the solution is much appreciated!
thanks in Advance
If I posted this in the incorrect place or there is something related to my issue, I apologize in advance.
I've been searching here and all over the internet and no progress yet so I decided to make a new account here just to see if anyone can help me because I'm out of ideas right now.
This morning my Nexus 5x (Non-rooted Nougat) woke me up like every morning, after dismissing the alarm I left it on my bed and when I came back to grab it later I noticed it shut off.
Here are the facts and what I have tried so far:
- Battery level was almost full
- I tried to turn it on but nothing happened, not even the Google logo
- Connected it to power and no icons or any response at all
- Left it connected for like an hour and tried to get it into recovery mode
- I was able to get into fastboot mode a few times but after electing "start" or "recovery mode" the Google logo comes up and then shuts off again right after.
- Tried getting into recovery mode after leaving it charging for a while again but I couldn't even get into fastboot this time, no signs of life at all.
- Disconnected the battery for a few minutes and tried to get into fastboot mode again, this time it worked but same thing happened. (Google logo then shuts off)
- Tried connecting it to my PC but doesn't show up on Linux nor Windows, on Windows it makes the sound like I connected a peripheral but that's pretty much it.
- I have USB debugging enable but never accessed my stuff through usb connection because I have had this issue before where it is connected but it won't show up or it shows up but won't let me access the files even though the phone is unlocked.
At this point it just won't do anything and I ran out of ideas. I just want to at least recover some pictures and information I have in it that isn't backed up, if anyone can help me I would greatly appreciate it.
Thanks in advance
It sounds like you might have encountered the hardware bootloop issue. This is theorized to be caused by bad solder for the eMMC chip or bad eMMC chip. This was an acknowledge problem on a related model LG phone, but hasn't been acknowledged for N5x.
If you are under warranty, you should start the replacement process before it runs out.
If you want to try something that sounds crazy but has worked for some people, put the phone in the freezer for 15 minutes then see if it boots. If it does, quickly back up as much data as you can, then wipe the phone in preparation to RMA exchange.
Just boot to bootloader (fastboot) then unlock it and flash a factory image... u can find many guides to this operation on the XDA

Same here... cannot enter recovery mode, so flashed new rom stock rom.
The flashing was fine but it didn't help.
guys if u can get to the bootloader, sure it can be fixed.. everything is possible with the fastboot, u can fix any issue. if it's a hardware issue the bootloader wouldn't work as well.

I've had the same problem with my 5X, except my alarm didn't even go off! I woke up 15 minutes late to see the boot screen "enter your pattern to start Android". I entered my pattern and it looked like it was going to boot up but when I went back to it it was blank. Tried again, got to the Google loading dots and it switched off again and I haven't been able to power it up since. No bootloader, nothing. Tried all the troubleshooting steps on the Nexus Google Support pages (I did post a link but because I'm new it won't show, so just Google "Nexus Support") and nothing worked. I also knew the battery was fully charged because it had been on charge overnight and when I did get to the 'enter your pattern' screen, the battery icon in the notification bar was full.
I requested a call back from Google and nothing happened so I tried the chat and they said it sounded like a hardware issue and are sending me a replacement device within the next 3-5 working days. Good that they're replacing it. Bad that it happened on a device less than a year old and they only offered £10 Play Store credit by way of compensation, when I've had to spend £15+ on a PAYG sim card to use in my old phone in the meantime because the nano sim in my 5X was too small and I've spent over an hour and half this afternoon wasting my time with troubleshooting and waiting for a call back... Not really the customer service I expected from Google for what appears to be a hardware issue. If you bought the phone from Google, my advice would be to get in touch with Google Support and they should replace it under warranty.

I contacted Google and they didn't help me at all because my warranty expired last month, they literally just told me to put in a repair request at the LG repair webpage....this sucks
My experience exactly...
My wife's Nexus 5 exhibited the exact same symptoms this morning. It's been running perfectly for 20 months and today it died, and we're unable to even get into the bootloader screen or power on the phone.
Taking your advice, we put it in the freezer for 15 minutes and were able to perform a factory reset wiping all data from the phone. We are going to take advantage of Google's Christmas 2017 promotion and return the Nexus 5X and buy a Moto 4X. They require you perform a factory reset before returning the phone in order to receive a credit for the returned Nexus 5. Thank you so much for the help!

I've just posted this thread overlooking yours. I think this is becoming another common issue. Has the freezer trick worked with anybody else?
I am having the same issue described here. My Nexus 5x went into a Bootloop about one month ago, but I was able to get it working again by going into Recovery Mode. About 4 days ago it went into a constant Bootloop, just showing the Google screen, and I couldnt get back in to recovery mode. I ordered a new phone on Tuesday (Pixel 2) and as long as I am able to do a factory reset I should get a $150 credit when I send this phone back. So, in desperation, I took a chance on the 15 minute freezer trick, and it worked! I was able to get into recovery mode (power + volume down, select Recovery Mode, little dude on his back came up, pushed power + volume up once) and cleared the cache and applied the factory reset. Ridiculous that this phone only lasted 18 months, but if I get the $150 credit I will be happy.
Same problem here -- just froze for a few seconds, powered off, and won't turn back on. Not a boot loop issue as there is no response at all from any buttons. Swapping the mainboard from a working phone powered up without a problem, but obviously that's the other phone's emmc.
I tried the freezer thing and it sort of worked- LCD powered on for a couple seconds, but then shut back off again and even that only happened once. That's progress over the usual absolutely no response though... Anyone have insight into why the temperature would matter? something is overheating that this gives a bit of wiggle room since it starts much colder than usual? maybe a more complex analog electronic situation?
I would happily pull the flash chip off and put it in a emmc reader, but I think I'm out of luck because from what I've read the dm-crypt key is generated from some data stored in in the processor's trust zone thing. I know the "password" but if that's only part of what makes the key and the rest isn't on the flash chip I suppose there's no point in going that route.
I don't care about the hardware surviving; mostly just looking to recover my data. Anyone have suggestions? Hardware debugging direction? I'm willing to buy some electronics test equipment (within reason of course; not picking up a 10000USD rework station for some old photos and contact list...)

Same problem here -- just froze for a few seconds, powered off, and won't turn back on. Not a boot loop issue as there is no response at all from any buttons. Swapping the mainboard from a working phone powered up without a problem, but obviously that's the other phone's emmc.
I tried the freezer thing and it sort of worked- LCD powered on for a couple seconds, but then shut back off again and even that only happened once. That's progress over the usual absolutely no response though... Anyone have insight into why the temperature would matter? something is overheating that this gives a bit of wiggle room since it starts much colder than usual? maybe a more complex analog electronic situation?
I would happily pull the flash chip off and put it in a emmc reader, but I think I'm out of luck because from what I've read the dm-crypt key is generated from some data stored in in the processor's trust zone thing. I know the "password" but if that's only part of what makes the key and the rest isn't on the flash chip I suppose there's no point in going that route.

The only way to connect that buddy to PC is to get SoC (CPU) working, so theoretically you can go towards reballing the chip. But I guess it's not an easy thing for such a little chip. Also u will need kinda plate for balls, i think there are no common ones, so u can make it yourself if have a technical education.
Another way is to connect memory right to PC without a phone but with some connector. IDK if there are any available, but this looks much more simple. I actually got the same happened, and tried to heat the plate, but with particular success.
IMHO

Here's the reader
https://www.amazon.com/ALLSOCKET-eMMC169-Programmer-Kingston-Interface/dp/B06Y55DKND/
But I assume the problem is I will not be able to generate the encryption key because part of it is in the processor.
If someone has tried this and it definitely works, I'll give it a go. Just don't want to buy the emmc reader and heat gun this chip off if it's certainly a waste of time.

I've seen a post of a guy who sent his motherboard to china and got reballed it and gained 4gb of ram. Can be wrong, but it was around $50 and a month of time.

Hi
The other day I was looking for cell ID info on my LG G4 that I have had for a long time in the "hidden menus". I accidentally clicked on the radio test and the screen froze up. I tried to get out of it, but noting would work, not even the power button. After a few minutes, I saw the power off sequence. When I went to turn if back on, it would not power on. I plugged it in, no charge. I tried to boot to recover, nothing. I have the service manual for the h815 variant which differs from mine. I do not have a boardview or anything.
I know trying to permanently fix it is a lost cause, it is old and it had other problems, such as the headphone jack not working even after I replaced it, and the read camera's autofocus being stuck after I replaced it with a cheap knockoff. However, I want to get it running long enough to get important things off of it. I was foolish and a few of my 2FAs are only on that device, and while I have gotten most of them switched to my alternate, I need to make sure to get the rest. I'm not sure which troubleshooting route to follow: Power? Crash/No Boot? No charge? I would follow each but some of the differences between the board I have and the service manual includes a few of the test points I need. Currently I have to attach wires to my multimeter leads to get small enough tips.
If anyone has anything that can help me get this running for a bit, let me know please.\
edit: biggest problem is I don't know how to tell from the schematic what pin is which on the board

Sounds like the ilapo but as you have modified the hardware it can be everything of course . anyways it wouldn't hurt to try some of the Bootloop fixes which you can find in my signature . Your best chance might be flashing the TWRP version for the ilapo and trying to load the recovery. Another option is of course to get into download mode and use salt to backup the user data partition.
Ilapo TWRP (when your device is unlocked only):
