Hiya,
So my colleague gave me an USB stick for me to copy some photos on to, and it seemed to of killed my N7.
Here's how it all went down:
I have an Intel MBP and when I plugged the USB drive in, it didn't recognise it (it didn't even show up in the Disk Utilities). And yes, it was directly connected to my laptop, no USB hubs involved.
I tried even the other USB port, and even with a USB hub, no difference.
I've installed a program to write onto NTFS formatted drives, and OS X natively can read just about all the Windows file formats (in my experience any way). And so, just for the giggles, I popped the drive into my updated and rooted N7 via a Motorola USB OTG cable (which has worked for a long time and no flaws) and then my N7 could read it. No worries.
I copy all of files into a separate folder on the drive, and then pop it back into my MBP. It then detects it. Very strange. I copy over some files, and unplug. Later on in the day, I remember that I forgot some files, so I plug it back in, and my laptop starts going into some crazy lag mode as if it just got Parkinson's. Unplug the drive, and then it freezes (i have to do a force shut down) and when it boots back up, it's seriously FUBAR'd.
I felt the drive belonged in the pits of Mordor with what havoc it was causing.
I didn't plug it back into anything else after that. Told my colleague and he did a virus scan on his Windows work comp: nothing.
Battery dies on the N7 (ie, ran out), and when I go to charge it. Nothing. Okay, something happens. The backlight goes on, but no battery symbol. Just see some sort of light leek (which I had before, but nothing dier.)
It's a 32GB CC0K "generation".
Any clues, tips?
Thanks for any and all help!
TL;DR version:
A) Big long story about MacBook Pro and a wonky USB drive.
B) Separately, "Battery dies on the N7 (ie, ran out)", N7 won't start up.
Not clear from story if (A) has anything at all to do with (B).
Try charging battery for a while? Hold Power button down for 20 seconds afterward? If not, unplug battery connector, wait 10 seconds, plug it back in, charge device, try to reboot?
There have been a number of similar sounding stories on here. Some of them seem to self-resolve after charging, some of them are reported to respond to various voodoo operations (e.g. battery disconnect/reconnect), some of them the person making the report never checks in again. I suppose that leaves open the possibility that some devices never turn back on?
It isn't obvious if there is a single syndrome or mutiple problems that exhibit similar symptoms.
good luck.
Thank you for shortening it!
I tend to go a bit overboard with details and what not.
Ok, will try having it in the charger and see what happens.
Thanks!
I also find it strange that a USB drive could be so destructive. However, if you do have a wonky USB drive, what chance of is there for its faultiness doing harm like I just described?
Don't forget to make sure the internal battery lead isn't disconnected!!! It happens..
Ok, plugged it, it sat in for a while, held the power button for a few seconds longer (along with the bottom volume rocker) and it turned on!
So, thanks for the help!
Must be the 100th time I've read about grouper's funny little "death" because of drained battery. Hasn't happened to me but if it ever does I'm prepared and properly informed lol

Hi everybody
I have a problem with my Galaxy S5 (no custom rom, official)
I normally used my phone, I locked it. But, after about 10 mins I tried to unlock my phone, but nothing happens
I tried to reboot, nothing happens. I tried take out and put the battery - nothing happens. So I searched on Google and tried some keys combinations, but nothing happens. My phone has about 80% battery. I tried to charge it in the charger, but nothing is happening (black screen, no notiffication light). Also I tried to put off my SIM and SD Card, but nothing happens
Do you have some skills in it? Can you help me?
Few days ago, I faced the same problem..
http://forum.xda-developers.com/showthread.php?t=2853472
Then I'd to take it to the Samsumg store.. And they return it back in 2 days and said me it was a software problem..
I wanted to do a recovery reset, but i can't boot my phone anymore, also the Kies doesn't see anything, so. Did you really think that is a software problem? Because my phone won't vibrate at boot. So maybe it can be a hardware prob :/
EDIT: Phone started blinking red light... (nottiffication), I tried to charge it, but nothing...
Mate as mentioned early, same problem I faced..
It'll be better, if you return it to Samsung customer care..
You seem to be saying that the problem occurred unexpectedly. So presumably this isn't subsequent to a flash error, newly installed app or a trauma (dropping the phone, etc).
First ensure that your battery is charged, plug in the phone to a charger as well and try turning it on. If at all possible, borrow a battery from a friend's S5 or go to a store and borrow a battery for 30 seconds to confirm that the battery isn't the issue.
If the problem persists, then remove the cable and battery. Then put the battery back into the phone and press and continue to hold in this order, the volume down key, then menu key, then power key. Hold all three until the screen powers up (about 5 seconds). If this doesn't work.. the most likely problem is a damaged power key - try pressing hard or "wiggling" it to see if that makes a difference.
If you still can't start the phone, then see if a local cellular repair shop has a "jtag jig" that you can borrow. Or you can buy one on Ebay for a few dollars. When this jig is plugged into the USB socket, the phone should automatically restart.
If all of the above fails (which is unlikely), you would seem to have a hardware problem or unknown origin. Which would be very unusual. If your phone is under warranty, make a claim. Otherwise get an estimate to repair it.
.
If I hold all 4 buttons at the same time and connect the phone to PC, PC recognises the phone for a few seconds. Well, maybe not recognises, I cant see it, but it plays the same sound as if connected flash drive to pc. However, everytime it disconnects within a few seconds...
I´m in the same case, but I was flashing the Galaxy S5 with the four files ROM and the pit file using Odin3.09. All the process ended well, but after rebooting there apeared one Screen sayin something like "Some files at this phone are encripted and there can´t be modified......." so I did a manual reboot and take off USB cable and from this moment the phone don´t do anything but giving a sound when I plug USB to computer cable and I can see new COM --> Qualcomm HS-USB QDLoader 9008, and there repeat a loop.
I´m still looking for a solution, but it gives me that there is time to change phone.
Possible Fix
This thread is old but idk if this was ever solved, so in case anyone else ever has an issue like this. My Gf is still rocking this phone so i've had a little experience with it. The phone wont turn on or charge. I got it to work by sticking a flat head screw driver and prying it fairly hard against the bottom of the battery (the side closest to the charge port) and forcing the battery harder against the metal contacts. While pushing the battery I turn on the phone and it starts right up and continues to run even after letting the pressure off. I've noticed this happens every few times i take the battery out, but this method has never failed for me turning the phone back on. Hope someone finds this helpful.

weird, youd think that bending the tabs out to force contact with the battery better would do the same trick fwif
So I was using my phone (with 1-2%) and someone called me, so I forgot about everything, and I went to talk. I was talking something like 5 mins, and then it stopped. Nothing to worry about, I put it to the charger, but the notification led didn't even started. Tried to boot up, no even a vibration, after 5 min, I tried again, I could heard very small vibration. I got worried, I waited like 20 minutes, still nothing, but the vibrations we're powerfull now.
So my phone is detected by qdloader. I tried with flashone+qfil, succesfull BUT STILL COULDN'T POWER UP. Ok, tried qtps, exactly by tutorial, everything was done, succesfull, BUT STILL ONLY VIBRATES AND NO SIGN OF LIFE, not even notification led when I plug it into the charger. No nothing. So, battery "somehow, I guess" isn't dead. It is soo strange. I contacted @tsongming and we try to fix it later at night, but until then if someone has an ideea or had the same problem, I would be very gratefull, it would be a disaster now to lose this phone
tldr: discharged, put to charge, no led no life, only warming up and 9008 mode works. Qfil doesn't help.
@F.J.V any ideeas ?

Change the graphics card to see
I do not know what to tell you, maybe so much overclocking ...
I can only tell you that I had a terminal that I left flashing, I forgot and the next day it seemed that everything went well, but the terminal did not do anything.
The terminal was dead, it did not charge, it did not vibrate, the computer did not recognize it, we go as if it had been fried.
After a couple of weeks, the terminal was still the same, it did not matter if I left it charging, it did not react to anything.
At the end I opted to open the terminal to see if I saw something melted, everything was fine, provided with the screen disconnected in case it was the problem and nothing, but ... I disconnected the battery for a few minutes and when reconnecting it the computer recognized 9008 I gave him the qfil and the mobile was as good as new.
The hardware is very damn, sometimes the least unthinkable fails. I have an old notebook, which once stopped working, did not start, but apparently everything was fine. I completely disassembled it and I did not see anything strange, but when I mounted it again it worked perfectly. But every two or three weeks the same thing happened to him. I was trying disconnecting and connecting pieces to see if I found fault, until I discovered that it was the screen.
The fact is that every time it happened to me, I would disconnect the screen, reconnect it and fix it. The funny thing is that there came a time when it did not spoil anymore, now even if I just take it never fails.
I think your failure can be something of that, the bad thing is to open it, but if you can not fix it via software try disconnecting the screen and the battery for a few minutes.
Greetings.

Now I can't even enter in 9008 mode. What the .... you have telegram or something so we can talk more in depth about this problem ? I really need this phone, and it's a really strange case After some time, the vibration got very low, and 9008 doesn't even get detected anymore.

We worked on this for a while, I agree this issue is hardware based. Unfortunately it could be anything, in my case disconnecting and reconnecting the battery did not work.
In his case, I am thinking that it may be a shorted usb card, especially because of the port issue.
Symptoms are zero battery, very soft vibrations and after a while at rest vibrates stronger for a moment and stays at zero.
As I mentioned in my case, the USB port did not work at all, neither recognized the computer, nor charged the battery, for some reason there was a blockage that only deactivated when disconnecting the battery for a few minutes.
The USB port is usually burned in the load, but it seems that this is not the case, unless it burned with the battery charged, and when downloading and trying to load appears the problem.
I hope you are lucky.
P.S. I suppose that D1stRU3T0R has tested with another usb cable and another PC

I bought another cable now, and the symptoms are the same. Also tried on another laptop.
So, if I charge it now, it's vibrating every x seconds (something like 10-20 sec), even without touching it. BAttery getting warm when charging. 9008 mode still disappeared for no reason.
So, by judgind this: Battery: Cannot REALLY be, because it's still alive, charging and somehow working. Maybe the voltage dropped and the vibrations are the sign of it?
Port - Don't believe, I can clearly charge it, so what's the problem here?
Motherboard/CPU - hmm, still doing something, something is controlling the vibrations, so not really
Soft - maaaaaaaaaaaaaaaaayyyyyyyyybbbbbbbbbbbbeeeeeeeeeeeee, when I used qpst, I didn't installed qfil with erase option, maybe that would help. When I tried to do that, I got a sahara error(maybe I did something wrong) than I lost 9008 mode.
Today, I got another ideea. Maybe I bricked the UFS memory ? it can't load anything, soooo...... it doesn't start, doesn't know what led color to select? And the vibration is just a sign....
Tried QFIL, 2-3 times, 2 with flashone 1 with qpst.
I went to 3 services, all of them refused me(one only fixing easly fixable phones, another was pretty **** service, and the third .. well I refused it, bcs he said he can try, but he doesn't quarantee that he can open the phone whitout breaking the glass ) But maybe I will try that. I bought another cable to try that EDL force flash, but tsongming is offline, so maybe tomorrow. I'm having some bad times bcs of this loss :crying::crying:
The glass is very hard, I doubt it breaks, but do not pay much attention to the videos that are out there of leeco. If you have never done it better, do not do it (as it happened to me).
I give you some advice in case you try.
Try to use only heat, I do not know if a hair dryer will work, better a heat gun.
Try not to introduce anything to separate the glass, at most a few millimeters, because you can damage the back of the screen and then it looks bad. Above all, do not put anything under and on the left, because you can load the connection strip and goodbye screen. Do not insert any plastic card to separate, because it will fill with glue and will damage the back of the screen.
When you take out the screen it will be full of glue everywhere. In the videos of youtube it says that you scrape it, but it is very easy to scratch the edges or the top part, if the stripes will be transparent and the backlight will be seen.
Do not even think about using a product to eliminate the glue, the screen will be deformed and you will never look good.
Well, you know what you should not do, to see if someone can explain how to do it correctly.
Once you take off the screen remove a small screw and the connector with a slight pressure, then you will have to remove a few more screws to remove a metal plate to access the battery, it may cost a little because it is stuck, but make sure you remove all the screws.
Once you remove the plate you find the battery. If you think it's okay, do not try to remove it, because it's stuck tightly, simply remove the connector for a few minutes and give the power button a moment before reconnecting the battery again
The USB port has not been removed but it seemed easy to remove.

Absolutely it sucks that you have these issues, I know how it feels.
But we need to clear a couple of things up, first just because the battery vibrates doesn't mean that it has enough charge to operate the phone. The battery may have enough charge to vibrate but not enough to power up the phone. > The battery would still be shot.
Next, to remove the glass, carefully and briefly use a Heat Gun. The screen can then be removed with a cloth to protect yourself from the heat, no guitar picks needed, no chance of breaking glass. Leeco simply uses A LOT of glue.
QPST use isn't related to the port issue, the port not showing is a driver issue.
The erase function of QPST clears items in the NV memory and then are backed up automatically during the download/restoration process per QPST user guide.
From QPST Technical Journal:"Nominally, each NAND block will survive 100,000 PROGRAM/ERASE cycles With an HDD, as long as there is no failure of mechanical or circuit parts, data on the platter (disk) can be rewritten for an almost unlimited number of times."
When something goes wrong
It's either drivers, improper QFIl preparation, windows related issues such as antivirus/windows security is not fully disabled, or damaged hardware.
Edit: It seems that @F.J.V already covered it.
@F.J.V new update, so my phone is now opened but the beginner at the service said that the motherboard is dead, didn't specified more. The phone is still open, and after 2 days I'm going home to check what's up. Any ideea what to check ( with voltagemeter, or to try plugging in whitout battery etcetc, checking battery voltage )

If the battery has an acceptable voltage, plug it in, do not connect the screen, and test if it recognizes 9008.
If it is totally downloaded, you have to try to load it in some artisan way, and do the same test, without plugging in the terminal screen.
If it is impossible to recognize 9008 almost certainly the motherboard is broken, but as the port of loading, which also manages the data between terminal and pc, is worth little money, you can try a new one. If there is not 9008 something on the motherboard is broken, and I do not think it's viable to find out the problem.

I had 9008 mode, and there are 2 people, tsongming and noel who can backup this theory. Even after I got the brick I had the 9008, but only after somehow it died. Maybe I tried qfil too many times, or I charged too much ?

Hi, I'm not a terminal technician, so all I can say are simple theories, similar situations that I've read or things that have happened to me, so what I say can work or not
I do not think that his problem is present in many flashes, or in many qfil, it would happen to more people.
My intuition tells me that it may be forcing the processor for a long time.
Well, what I can assure you, because it has happened to me with an X722, is that sometimes there is some type of blockage that leaves it totally dead, and the only way to make it work again is to disconnect the battery for a few minutes. In my case, there was no 9008, it was not charged, it did not do anything, but when I removed the battery and plugged it back in after a few minutes, the 9008 returned and I was able to retrieve it with qfil.
Also, and this is just a theory, I think some of the terminals when in edl mode, even if you put the charger and the terminal is hot, in reality the battery does not charge.
In my case, the terminal was connected to the PC one day after making a qfil, when I went to restart it it was already dead, it got stuck for a week in the charger, but when I removed the battery and reconnected it, the battery was for the minimum , but it worked, I passed the qfil and I was able to load it with the new rom.
By this I mean that I think the lock was caused by not restarting after qfil and running out of battery, despite being connected to the PC, which in theory should charge the battery.
So I recommend whenever you can, and more if you have the terminal open, disconnect the battery, but this is not a miracle, is to discard this rare block that sometimes suffers.
It is not the first time I see that a leeco has run out of battery and could not be charged in any way, the only way has been to change the battery and pass the charging port, but I do not know if these people tried to reconnect the battery and make a qfil later, the same would have saved a new battery.
If your problem is the motherboard, I recommend that you look for YouTube to repair the graphics card of a PC. Generally, overclocking damages it, but it does not break, it's because the chip reaches temperatures so high that you can lose a solder, which in some cases can be easily repaired with a heat gun. I know people who have worked for him, it's easy, you just need a heat gun.
I hope you can use some of what I told you, it worked for me to disconnect the battery, but Tsongming did not work.

hmm, so in 2 days i'll try this. DIsconnect the battery and let it like that. Also can I connect to the PC whitout the battery connected? Also, I can try to see if the battery is warming up, not only the motherboard or whatever, cpu.
This OC what we're using aren't damaging our hardware. Believe me, i'm OC-ed, and I overvolt and overclock for almost 50% stock speed and still didn't broke anything (top 1 hd 7750 on userbenchmark, biggest benchmark site)
My phone doesn't turn on nor can it turn on in recovery mode neither and seems to be dead... The only signal of life is the blinking white led next to the fingerprint scanner.
Here's how this happened: The phone was charging very slowly, I thought this was a problem with the cable so I tried other ones without success, I continued using the original, days later it stopped charging so I opened the phone very carefully and saw the battery conector raised ever so slightly, I pushed it back in place and noticed that the flash flex cable had some kind of bump that was caused by some kind of chip under it, maybe I sat on my phone some day and caused this but I don't really know. So I reassembled the phone and now it won't turn on.
I've tried to "unbrick" the phone since apparently that's what causes the blinking white led and not being able to turn on the phone, but unfortunately, the phone won't get recognized when connected to a computer, this means I can't do the unbricking.
I want to know what else could this mean? Is the motherboard dead? Would the led blink even when the motherboard is dead? What can I do?
I've tried(in order to get my phone to show up on the computer):
*Using different kind of usb cables(including the original).
*Connecting to other computers.
*Installing Qualcomm and Motorola drivers.
*Running PC on test mode and disabling signature checks.
Please tell me your opinions, do I buy a new phone or is this fixable?
Originally, I would have thought your issue might have been to do with the charging port (possibly explaining that your device can't be identified).
Just to confirm, all the connectors that you saw, including those attached to the motherboard, are all connected and it's a good connection?
It's entirely possible the motherboard/flash memory is dead - so not being to load the bootloader, though I would have thought you'd be able to see Qualcomm HS-USB 9008 in Windows if your device can't boot to the bootloader (it'll drop to the Emergency Download Mode).
I honestly do not know what the issue/issues might be, though you could take it to a service centre/repair shop and see what they say (get them to inspect the device). Given what you've described, it's possible you may be better served by a new device rather than spending money fixing up this one.

It's entirely possible the motherboard/flash memory is dead - so not being to load the bootloader, though I would have thought you'd be able to see Qualcomm HS-USB 9008 in Windows if your device can't boot to the bootloader (it'll drop to the Emergency Download Mode).
I honestly do not know what the issue/issues might be, though you could take it to a service centre/repair shop and see what they say (get them to inspect the device). Given what you've described, it's possible you may be better served by a new device rather than spending money fixing up this one.

Thanks for the reply, I checked all connectors and none seem to have problems so I'm going to take it to a repair shop as you say, depending on what their diagnose is, I'll consider buying a new phone. Once again, thank you.

My phone doesn't turn on nor can it turn on in recovery mode neither and seems to be dead... The only signal of life is the blinking white led next to the fingerprint scanner.
Here's how this happened: The phone was charging very slowly, I thought this was a problem with the cable so I tried other ones without success, I continued using the original, days later it stopped charging so I opened the phone very carefully and saw the battery conector raised ever so slightly, I pushed it back in place and noticed that the flash flex cable had some kind of bump that was caused by some kind of chip under it, maybe I sat on my phone some day and caused this but I don't really know. So I reassembled the phone and now it won't turn on.
I've tried to "unbrick" the phone since apparently that's what causes the blinking white led and not being able to turn on the phone, but unfortunately, the phone won't get recognized when connected to a computer, this means I can't do the unbricking.
I want to know what else could this mean? Is the motherboard dead? Would the led blink even when the motherboard is dead? What can I do?
I've tried(in order to get my phone to show up on the computer):
*Using different kind of usb cables(including the original).
*Connecting to other computers.
*Installing Qualcomm and Motorola drivers.
*Running PC on test mode and disabling signature checks.
Please tell me your opinions, do I buy a new phone or is this fixable?

Try to hold the power button and the volume down buttons together for more than 2 minutes. My moto g4 goes dead sometimes and nothing I do will turn it on except holding those buttons for like 2 to 3 minutes then it reboots to fastboot and turns on. It might not work but it works for mine and its worth a shot. It takes a few minutes and I dont know why but it does no more 3. Let me know if it worked.
