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
Hi! Similar problems have been posted on the forum before, but none of the solutions worked for me.
Stock Mi A1 with vanilla Oreo (latest official patch), everything stock & vanilla, no hacking, no rooting, no modifications etc whatsoever. All apps installed through google store, nothing fancy.
In short: put my phone into airplane mode about a week ago (battery at 90%), then a few hours into the flight the phone blacked out. Won't react to power button, power+volume up, power+volume down, all buttons, no buttons, any combination of buttons for any length of time. Phone was in my pocket, no physical impact or anything, just "died".
There are 2 signs of life:
- If i plug it to charge the notification LED blinks about 1 / sec
- If I connect it to a computer, it recognizes it as Qualcomm 9008 blabla device.
What I have tried so far and didn't work:
- All imaginable button combinations: no reaction
- Fully charging phone: doesn't help
- Letting battery deplete: doesn't help
- Disassembled the phone, disconnected the battery, put it in charger, reconnected the battery: this fixed the issue for some, didn't work for me.
I GUESS that since the computer recognizes it I could try to "flash" it or whatever, although 1) there are a lot of negative posts about it 2) I have no idea how to do it (which exact ROM, using which exact tool, etc).
I wouldn't mind not losing the data on the phone though, if that is an option: I was about to back up my photos on the flight, but it died before I could have done it.
There is no official Xiaomi support / service where I live, bought the phone while visiting a country which sold it.
Any suggestions?
Small update.
- adb doesn't see the device.
- Miflash sees the device, but dies at "ping via firehose" stage.
-A1 low level backup tool doesn't see the device.
After 2 weeks of googling I have found around 50 forum threads around The Internet with similar issues, but no solution as of yet. Sounds promising!
I had this problem 2 hours ago and fixed with the Disconnect battery, connect charger, reconnect battery (while charger is still connected just to clarify). you tried this fix like this? reconnecting battery while charger is still connected?
Maybe try getting a different battery and connect it, and/or maybe let the battery discharge itself.

Thanks for the replies fellas. I have tried this before. Now I have tried this again just to be sure. Did it multiple times. Disconnect battery, connect charger, reconnect battery. It doesn't alter the phone's state in any way. Doesn't react to buttons, flashes led on charger, shows up as qualcomm 9008 device on PC, but doesn't let me flash anything. Sad.
Qualcomm 9008 is sigh of faulty emmc chip. Bad soldering i guess. Take the device to the service center. My 1 cent op. Regards
Its very simple the solution. The problem is the cable. Try to change the cable, charging the phone and turn it on. I my case works

Have you had any progress? I'm having similar issues with my mi mix 2s.
The answer is to replace the battery. I have two dead batteries for my Mi A1. Both batteries were left in the drawer for several months and upon connecting them to my Mi A1 they showed the dreaded blinking light. After trying to fix this for a day I gave up. I disconnected the battery, the phone booted up right away. Bought a new battery and everything is working again. Hope this helps!
I too had numerous kind of hard bricks with my previous smartphones.
Here are the links that will save your life:
Link 1
Link 2
Link 3
Try the ones that you think fit the most.
I had the same issue just today
removed the battery connector and connected it back without touch any other component
phones working fine now
its bricked and get into edl mode just try to flash with MiFlash tool i have faced this problem some time ago when i flashed an ota with twrp recovery then my phone went dead and when i connect it to pc led blinks and phone recognise in ports as "diagnostic port 9008d" something like that then i install the drivers and flash stock pie rom with MiFlash tool but after successful flashing phone wont boot but after pressing power button for 10 to 15 second phone starts. i have unlocked bootloader so it works for me but i'm not sure it works on locked device try it or use QFIL flash tool from QPST
This happened to me but all i did was charge the phone the whole time.
My Xiaomi A1 had the same issue, I think I have tried all available solution but unfortunately mine still dead, and when I connect the charger it blink.
I guess the ultimate solution is to throw it to a recycle bin.
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)
Please can someone help me with a problem I’m having with my Samsung Galaxy s5.
I put my phone on charge before I went to bed and when I woke up it was still showing a red LED. I knew this was wrong because it should have had enough time to charge and turn green. I had not powered the phone off before putting it on charge and I plugged it into the same USB 3.0 charging lead I have been using for the past six months. I unplugged the phone and pressed the power button to light up the lock screen but it didn’t light up.
I’m thinking possibly something has either shorted or over heated and fried something either on the charging port assembly or one of the chips adjacent to the port while the charger was plugged in. It seems like only a trickle of power is getting through to the phone. When I plug a different USB 2 charging cable into the phone, without trying to power on, the charging icon appears but shows no charge at all in the battery.
I have also tried the spare battery I have but it’s still the same. I know the spare battery is 100% fully charged because I store it in a separate charging/storage box which shows a green LED when it is full. In fact the one which was in the phone at the time is also fully charged according to the charging box. Neither battery has got warm at all inside the phone. I’m confident both batteries are fully charged and totally fine and the problem isn’t with the batteries.
At this point I removed my sim card and also the MicroSD card. I needed the sim to use in my spare phone and I wanted to see if the sd card could be causing the issue but after again trying a normal reboot it made no difference.
I’ve tried several possible things I found on google but nothing has worked. Between each different thing I tried I had to remove the battery for 10 seconds and insert it again to get it out of the boot loop so I could try something else.
Initially when I tried booting into safe mode, then recovery mode and then download mode it brought up the screens for those but in each case after a few seconds the phone powered off and went into a boot loop so I couldn’t attempt any recovery options such as clearing cache etc. Now I cannot even get it to start any of those modes at all and all that happens is the phone does a little vibration, displays the Samsung logo and then just boot loops no matter what I try.
I have tried removing the battery and leaving the phone for a few hours then powering on again but it still just loops.
I have tried pressing and holding Vol-down when plugging it into my PC using a different USB 2 cable and windows acknowledged a phone was plugged in but said it couldn’t connect or recognise the phone and suggested the phone could have a fault.
I don't know if maybe my USB 3.0 lead has a fault that could have caused it or if there could have been some electricity spike while the phone was plugged in, or as I said a component has just fried.
I strongly suspect this is a hardware fault and not a software fault but as I’m not a phone engineer I have no idea about how to trace any possible hardware issues or what might have gone wrong. I would really appreciate any help or suggestions about what the problem might be as this has been a great phone for the last 2 years since I got it and I’d be sad to have to junk it and buy a new one.
Thank you.
I would not junk it yet......
You had mentioned that you go through a lot, just to get phone into Recovery ( " Initially when I tried booting into safe mode, then recovery mode and then download mode it brought up the screens for those but in each case after a few seconds the phone powered off and went into a boot loop so I couldn’t attempt any recovery options such as clearing cache etc. Now I cannot even get it to start any of those modes at all and all that happens is the phone does a little vibration, displays the Samsung logo and then just boot loops no matter what I try." )
OK, just my 2 cents here on this... Why not trying to goto Recovery by pressing and holding the Volume Down (vol-); Home button, and The Power button all at the same time. (yes, if you have a Recovery, and its works, you should be able to boot right into Recovery- >Now, (I would, cause I've been there..) I would also have a PC going with Odin open (Plus the Latest Stock Rom) ... If it works, you would flash the Stock ROM, to clean up anything, giving you all stock, but you can change that of course ...then go from there...
Second, if you can not still get to Recovery.... Have you tried a Stock USB Cable, only asking.... Obliviously something is a miss... with Power... IF phone is off, and you plug it to a power source ... then system has power, and these can power up with just the usb cable, without having the battery in..... Been there. Can add the simple fact, if using just a Micro SD cable, they can bend the Power Board. Believe me (Had to fix the Wife's S5 a few Frinkin' times....) That is why, I say using the Stock Cable, or even a USB 3.0 Cable (like the stock one) does help with power issues when the Micro has bent up the power board...
Will check back and see if this may have you to Recovery or fixed... sure hope this can help you out
Thanks for replying godofsalt.
At the time the phone was plugged in to my USB 3 lead which charges faster and all I can think is that perhaps there could be a fault with the lead or the higher ampage of using this lead caused a circuit to burn out.
I have around a dozen USB 2 leads and I've tried your idea with 3 different ones but none of them will fire up the phone at all with the battery taken out.
I am sure this is going to need some kind of replacement either of the charging port or the motherboard. I don't rate my chances of trying to do it myself and I don't think it will be economic to take it to a shop so I've found a better option by buying the same phone which is second hand but in good condition. That way I know I have all the additional accessories already for probably the same price any shop would charge to fix it.
In future I'll stick to using a decent USB 2 lead on the 1 amp charger I used to use before and hopefully this will not occur again.
G500F battery graphic/boot loop
Had the same problem a few days after installing a 9.0 Rom. My battery is brand new and all cables aren't too aged, so I thought this had to be a physical fault of some kind, but then I had the thought to flash an older bootloader and just like that my battery started taking a charge again and I could boot up. Switched to Flyme os for a while the went back to 9.0 again, with the lastest bootloader and the thing stopped working again. Don't know too much, but I'd try and flash a different bootloader to see if there's any difference. My device failed right at the Galaxy logo, then looped the charging graphic endlessly but would strangely go into download mode and not fail. Don't know if this helps, just thought I'd share my solution.
Thanks for replying henderia93.
My symptoms are very slightly different in that the phone couldn't maintain any of the modes I tried for more than a few seconds before going back to the boot loop again so there was no chance of trying any software fixes including flashing the ROM. Now it won't enter any of those modes at all. I'm certain that's due to only a trickle of power getting through to the main board, not enough to maintain any recovery modes, so there is just enough power for it to attempt to boot, but no more so it just keeps looping, most likely caused by something that has blown while on charge.

I ha e taken so many of these a part... Like I may have mentioned, there is a Board, just for the USB (data and power (i still have 2 of them)).... In short, you really have to pretty much take the phone a part. Being very careful with the Screen, and the "Sticky" LEDs and the Home button. There is a lot to it actually.
Like I said, been there done that... Cheap to get, takes some time but it is possible to replace that board. It's a separate board different from the actual main CPU board.
I would have to find it, but I had a manual, for taking these a part.

While I've been looking for answers about this I've seen teardown videos for the s5 so I can see what the port assembly looks like with it's little PCB behind it. As I have a replacement s5 on it's way all I need to decide now is whether to keep the old handset for spare parts or see if I can follow the teardown video to try and install a new port assembly to get the phone working again as a spare.

Yep, me too, seen many vids on the tear down. I decided to go a bit more, IMHO, to have an actual manual, PDF, when I did my first one, many years ago. So, can read, and use photos wisely. Seen too many Utube crap, where the break it, destroy it..... crazy!
Well, at this age, not too sure what to do my self. In our case, our present service is cheaper to Keep these. Grandfathered in, and we pay a but less, than going to any other carrier. Plus, these newer phones are not cheap at all.
True, it up to you. hope all goes well.
Sorry I am a novice so please excuse my question.
Are you assuming that the usb port is shorting even when no usb cable is inserted? As you put a fully charged battery in with no change it would seem that the act of charging is not involved.
Have you tried a voltmeter to check the voltage at the battery charging pins?
Have you tried to check the voltage at the two pins commonly used for a wireless charging adapter (to the upper left of the battery) to see what the voltage is?
Sorry if I am off base.
