Phone shows no sign| Seems like a dead phone

So everything was working fine a few minutes ago until i put my oneplus2 in my pocket, after sometime when i removed it there was no sign, nothing seems to work, it wouldn't boot neither into bootloader nor into recovery, and when i charge there is no indication either, anyone knows what would the problem be? or is there any way to make it work?

have you tried to enter QHS HS-USB mode?

how to do that?

hold press volume up+volume down and plug in usb cable..see whether it detected something like QHS USB in device manager

bro it ain't detecting anything, everything was working fine then how suddenly it looked like it's dead?

Did you have a custom ROM on it? Did you install a custom kernel? Were you tweaking around voltage/CPU etc..values?
Some more information about the "crime scene" would be nice..

ok so i had flashed h2os a week ago everything was working fine until yesterday when suddenly it stopped showing signs, neither does it shows charging signs nor does it boots into bootloader or into fastboot mode, i did not tweak anything either, i charged it the whole night but it ain't showing any signs yet, battery was working fine the other day so can it just die so suddenly?

may be you should try hard reset.
check if it gets detected by your pc in auto restore tool software. your phone won't show any signs even if it gets detected by your pc in such situation.

but the phone is not detected at all

I'm trying to unbrick my x720 by QFIL but my pc won't recognize Qualcomm 9008 port

My problem is that I can't even try to do the procedure in the other threads that i've read because my pc simples dont recognize anything when i install the qualcomm drivers. Any tips? Thank you in advance. I want to try this thread [GUIDE][QFIL MODE]Unbrick your Le Pro3, tested and working. But simply the qualcomm port doesnt appear in the device manager.

Bad cable or need to reinstall drivers...

I tried with two different cables and reinstalled the drivers a few times now. No port in the device manager. Just the Android ADB Interface tha showed when I installed the leeco adb drivers. On the ports just appear the standard Comunication port and printer port. I tried everything, the volume bottons power, etc. The Flash One dont recognize the phone for QFIL.

I dont have hardware problems. I flashed the Pixel Experience rom in february with sucess but I didnt like it. It had too much battery drain. Then I wanned to try some other rom like AICP. But in the process of flashing something went wrong. I wasnt able to flash it, always gave me the error 7. Then it simply died. I was rebooting TWRP mode and it went dead. Now just vibrates when I try to turn on. I tried the QFIL process (both volumes + power) but I dont even know. How can we know that it in qfil mode? My pc wont recognize anything. Not in Flash One, Not in QPST, nothing. Am I doing something wrong? The phone vibrates so its charged. I installed the Qualcomm drivers properly, I thing, eventhow it doesnt appear the qualcomm 9008 port in the device manager. Its suppose to appear before the phone is pluged right? Thank you for the reply.

I've no idea how to help you... Sorry.

Instead of creating a new post why not just read the enormous unbrick forums that exists and have proven steps. Many, Many phones have been debricked using those steps.
Hint, read the last pages for updated links to the software tools needed.
Next, I just found this cable which will help immensely with unbricking your device: https://www.amazon.com/GPG-EDL-Cabl...r1&keywords=edl+cable+for+wall+qualcomm+usb+c

Completely dead, just vibrates when I press power and yes, I sometimes have the red light, sometimes flashing, sometimes stable.

Your phone is probably fixable.
Based on what you stated above, it seems that you downloaded and attempted to install the wrong version of TWRP and now your phone has no recovery at all.
Here is partial instructions I posted in the unbricking forum : https://forum.xda-developers.com/showpost.php?p=76100899&postcount=121
Use those instructions along with is mentioned below. I have personally helped so many people unbrick their phone that I have lost track and this is the reason why the posts are so long and extensive. Because sometimes what works for one person does not work for the next. So I have essentially have taken everyone's great advice and updated the links, made the instructions steps a little more concise and easier to read, fixed some incorrect steps or added the needed skipped steps. Plus added my own research into what I believe is now a definitive guide for unbricking the Leeco variants X720 and X727. The point of not reposting the information here is to keep everything from becoming more fragmented.
Yes, it's possible that you have a hardware issue. But, its also possible that it can be fixed!
Remember that you will not see the port unless you are in EDL mode
Just press volume △ (+) and volume ▽ (–) buttons together while powering the phone on.
It should now be EDL mode. If you cannot get into EDO mode, you cannot do anything else.
If you get an error, press and hold the power button while at the same time hold vol up + and down simultaneously plug the usb cord into the back of the computer while holding the buttons.
Yes, It's a pain and this is why the deep flash cable is handy....it's a special cable ( so your extra cables will do nothing to help you) The deep flash cable will automatically put your phone into EDL mode and allow you to use Flash on.
Install the Qualcomm QDLoader 9008 driver: https://goo.gl/9E3bKq or the from links provided in the unbrick forum.
There are multiple versions or Qfil, some have issues. I posted the correct one that works.
FOR anything else go to that forum read my and everyone else's posts. Again, I keep all of my linked files are up to date, and many are located on my own drives.
You can make one of these cables. Here's a video that shows you how:
https://www.youtube.com/watch v=kSiGsYK66gM&lc=z220yhtqvwyyct21pacdp432sh2xjecek10dae1jen5w03c010c.1524884617336803
it will not be a quick fix.
There are 4 or 5 different unbricking options and it requires persistence and patience.
The good news is that your phone has a solution that may work.

So when your where flashing a rom you got error 7 and your phone went dead.
I had gotten that same error.
Error could mean two things 1) update recovery or update firmware.
My point is sounds nice like hardware issue.
These phones are known for just dieing.
Also getting into that mode you have to push power+volume+volume- at the same time.

[SOLVED] A2017G Hard brick, Unauthroized ADB and DFU Only.

Hey guys,
Guess today it was my turn ****ing up.
I apparently have completely bricked my Axon 7 after trying to go from LOS 15.1 to stock oreo beta. The only thing I seem to be able to boot to is DFU mode and for some reason, if I press the Power button + Vol Down I will get stuck on the ZTE Logo and my PC will detect my phone through the ADB interface but every time I try doing something it says my device is unauthorized. Is there any way I can authorize the device whilst being completely bricked?
The only other thing I get is the unlocked bootloader warning screen. If I don't press anything the phone will be stuck there, if I select recovery the phone will simply shut down and anything else will result in a reboot. I have also tried a deep flash cable that that only results on the phone being stuck at the unlocked bootloader screen.
I cannot access the bootloader,
I cannot access EDL mode
I can access ADB, but device shows as unauthorized.
I can access DFU mode.
Any suggestions would be appreciated. I have looked at the Hard brick guide that involves taking the phone apart but that's not something I really want to do.
Thanks in advance.
Edit: My phone gets detected by MiFlash but every time I try flashing I get a cannot receive hello packet and object reference not set to an instance of an object.
ZTE axon 7 EDL tool detects it in ADB mode but says ERROR! NO ANSWER FROM PHONE!. Possibly since its not authorized with ADB.

Ouh....DFU? I think this thing is totally bricked.

I can access my phone in ADB. If only I could make it reboot to edl or something like that through ADB even though my device shows as unauthorized. That is the only problem why this thing is completely messed up.. ADB works but I can't do anything with it because my phone shows unauthorized. Does anyone know if there's a workround or a bypass for that?

Hi Victor !
Like we discussed before there is nothing much left as to use the DFU unbrick-disassemble guide or buy something like this to be sure you tried everything.
Good Luck mate !

Thank you for your help . It's a risk you take when flashing phones.

Can you get custom recovery in it some recovery allow you to get in to EDM from there you can flash stock rom with Mi flash tool.......try to push both volume buttons at the same time don't touch the power button this might get you in to EDM.

Nothing, you'll have to use my guide for that (the one that raystef linked). Otherwise try entering FTM mode (Power and Vol-) but it's surely not gonna work. If it does, you'll see a screen with a square that says "FTM", and you'll be able to do " adb reboot edl" and flash stuff from there.
Unbricking by disassembing the phone is the most reliable method; an EDL cable just might save you the hassle but it's not guaranteed to work; some phones won't accept it for some reason. In this case just follow the guide unless you want to try your luck with an EDL cable

Hello. Thank you for your advices, it is as I feared.
I have however already bought another Axon 7 which I'm using at the moment, and I have plans for mine since it was only bought new about 8 months ago and I believe I could get a replacement for a fee even if its bricked to fault of my own. So I will try that since I'm not in a rush.
This thread can be closed.
Cheers!

In that case you can just pretend that the phone got in that state by itself, it's not too morally correct but some people here pulled it off...

twice now i have gotten an axon 7 into this state. while mine have been a2017u models, i dont know that they are different than yours in that regard.
What worked for me the first time was letting the phone completely die. Being unable to boot into anything, it was somewhat a task to actually make it die, so i kept powering it on (which merely made the red led indicator come on). i did this over and over again over the course of a day at work whenever i noticed it had powered off.
eventually, the phone had no response at all. then, i plugged it up to my laptop, and left it, convinced i had killed it. a dialogue popped up after a minute or two on the phone screen saying to charge the phone by plugging it up. i had no access to fastboot or EDL mode prior. once i got that 'plug in to charge' screen, i switched it to the wall charger, and left it to charge a bit (50-60%) from that state, then, i unplugged it again, and somehow, i managed to get edl mode to work by unplugging it and pressing all three buttons and holding them (typical edl boot).
once there, i reflashed via MiFlash an earlier build. i rolled back using MiFlash as far back as i could. in the process, i lost my imei and serial, which i have yet to successfully recover, but i did get out of DFU pergatory. the imei thing seems to be caused by going back to MM which i did on both of my IMEI-less a2017u boards, but im only guessing. my dd axon 7 is the only one of the three boards with imei and serial, so maybe MM is a bad idea. lol.
The first time i recovered from DFU, i did it inadvertently by letting the phone die and then flashing in EDL mode as well. (i left it for a few weeks as i had given up on it.) after it died completely, and i plugged ut up to the computer and had the same experience, I flashed the beta oreo build for a2017 using miflash. the screen had stopped responding. and i ended up doing a RMA. I now know the screen response thing was bc of a faulty EDL file of B15. (happened again to another of my axon, so i retraced my steps and realized it was when i flashed b15 that it died) . the fix if your screen ever stops responding, but isnt physically damaged? re-flash via EDL a different file. it may take a few tries, but eventually a build will work. for me, it was Marshmallow. I still do not know for certain, but that possibly is what killed my IMEI. but hey, it boots and the screen works.
I genuinely hope posting my idiocy in toying with axon 7s has helped someone out there.

Dead Xiaomi A1

I have tried to upgrade my Xiaomi to Android 8.1 through flashing. I rebooted the device after fastboot. Now every time i hold the power button it vibrates like a heartbeat and stops when i let go of power button. When it is plugged in with the cable it doesn't stop vibrating (like a heartbeat). I don't know what is going on, hard bricked?? Is there a way I can fix this. Thank you...

I have the same problem after a flash with Miflash Plug in USB in phone keeps the phone vibrating but don't start up. Put the phone in EDL mode by test point method stops vibration.

White blinking LED = EDL mode. You can flash in MiFlash in this, with the right driver.
Check my thread, something called "Mi A1 Low-Level Backup Tool" or similar (i'm on phone) for details about EDL mode.
Just flash stock ROM in EDL mode, if it doesn't fix it then you have some serious issues (like damaged hardware).

@CosmicDan I know that white blinking led is EDL mode but for me it is something different.
I put my phone in EDL mode by test point method and the phone got recognized as USB 9008 or something like that. Than I open Miflash and my phone got successful flashed with stock rom. but after that it don't start up but only thing I see is white blinking led when I connect it to a charger.

So something else is broken then, something the stock firmware doesn't flash. Dunno sorry, could be hardware issue for all I know.

Oké thx I think I have to send him to a service center

Can anyone backup a rom of mi a1 using twrp? Then I could fix my Xiaomi

Bricked phone

Hello, i think my phone is completely dead. Here's what happened : i wanted to go back to a stock ROM so i used MiFlash, but it gave me an error really early after a couple seconds (modem flash error i think) and now it doesn't respond. When i connect it to my PC nothing happens (nothing in device manager). The only sign of "life" is that when the battery is low (i think that's the case), the LED starts flashing RED until the phone runs out of juice. Any ideas? I already tried charging the phone all the way up and then discharging it completely(those are the only things that seem to work as they should) but the phone seems completely dead. I had a similar thing happen to me before on my older Xiaomi phone but that time my PC at least managed to detect it in device manager as qdloader 9008 (EDL mode) but that just doesn't seem to work now. Would shorting the test points work to make it go into EDL mode or is it a lost call? The bootloader was unlocked before flashing and i chose the option in MiFlash that doesn't lock it again. Thanks for anything. EDIT: Phone sent to a repair centre.
