[q] hard bricked... - Nexus 7 (2013) Q&A

HeLLo , please be cool english isn't my mother language...
nexus 7 2013 . 16GIG WIFI
As it's my son's nexus i don't really know what was happened.
But he doesn't have the age to perform rom updating and this sort of things
As Nexus stayed blank, i thought it was battery , i change it without help.
when i put it in charge nothing happend. no white led nothing no screen
i tried the power + vol - reset ... nothing.
The only thing that i think it isn't completly dead, when i connect the device to Win7, a device appear in ports under device manager

Any reaction during charge: increase of temperature of charger and/or Nexus?

I changed the battery. the new one was charged / i had checked the 5V output .
do you mean that i had to check if the charger temperature is raising during charge ?

It seems that your Logic Board ( = the board with the RAM, SOC etc. ) is fried. The good news is, 16GB boards are still easy to obtain and also easy to replace.
Ebay still has plenty of those while 32GB boards are harder to get.

Thanks you .
Do you know how i can be sure of diagnostic ?

Try home+power+vol up+vol down and hold it for 1-2 minutes or until something happens? Try it also while it's plugged in.

Does it still connect to a PC? If so you can back up all your data if it still connects

Which of the steps suggested have you tried? in terms of holding the power + vol up + home button?

1. Home + Vol up + Power.
2. Home + Vol down + power
3. Home + Vol down and Vol up + power.
4. Menu Touch button + Power.
And i did all this connected on PC, Disconnected, Connected on a original Wall Charger and on a parallel wall charger.
Do you even get the noise on the pc to detect that something is connected?

Hi Gustavo,
Sorry I'm new member but may be able to help you with this.
I had a similar experience with my son's tab 3 kid's edition last year.
It just died and wouldn't turn on. I tried everything but no luck. I then decided to take the tablet back to samsung store and packed it. I was suppose to go the store 2 days later but after 48 hours of device dying I just thought of trying to turn it on and plugged it in to the wall charger.
To my surprise display came on showing red battery icon and after 30 mins approx, device showed green battery icon still charging. after roughly 10 hours I turned the device on and it works flawlessly since then.
Hope this helps.

Hi! Thanks for the help! But before i make this topic i waited for 3 days to put tablet on a charger.... nothing happened =/ But i'm gonna try again!
I had a similar problem.
Do you know how to separate the screen from the body? I found that the connector at the base of battery was very loose. I managed to push it down and it turned on right after.
Hope this helps!
Whilst I agree it could be a loose connector, it would void your warranty. I would see about going to your local samsung repair centre and see if they can have a look without wiping.
This happend to my 8.4 last week, no way to revive but i can feel warm at the back while doing all the first aid trix but no luck. So i decided to bring it to the nearest samsung store w/repair service they remove the back cover and battery, they told me they just ¿¿refresh start?? the battery? because it was drained!!?? wtf i remeber i left it with 30% charge... but anyway they fixd it in less than an hour. But yesterday the symptom returnd again i have to power+down+home just to turn it on :/
Plug in the charger then press power + vol down (not up). Hold for a good while until it restarts.
If it doesn't then it could be hardware related.
With so many people reporting battery problems, you might just have a bad battery and that's why it gets hot when connected to a charger. *I* would open it and check the battery's connection and maybe even replace the battery.
I saw some videos...but i don't want to void warranty :/

HTC One M8 not turning on or charging

Installed Viper Rom 5.0.2 running normally for around a month.
I plugged the phone as usual for charging in night at around 15% battery level.
In morning phone was dead.
Left it charging for a while but unable to switch it back on.
No led comes up while charging.
Did lot of research online and Tried all methods like pressing Power + Up or Power + Down or Power + Up + Down for a while for switching the phone on.
But no response from the phone
Also when I put in the micro-usb socket (when attached to charger or computer) while pressing power + volume up buttons the led flash orange for a second.
Connected with PC shows up as QHSUSB_BULK under device manager.
Please help in reviving my phone.
Thanks

How long is "a while"? Let it charge for several hours (overnight) and try another cable and charger, in case the first one is broken.
Then try to hold power+vol up (or power+vol up+vol down)for a minute or more.
The fact it flashed an LED at all is a good sign. A true brick usually has not LED response.
OoohhhI KNOW...
****...i hope i am doing this rite...
Anyway...what you do is so the volume up , power , and the return buttons all at one time...until it turns on....leave alone so it can reboot.
It should be good to go...
Seriously i found if you do this to any device acting unusual...even for
volume issues...check your devices cpu..if it runs hot a lot,
i found this to be related somehow in the htc..
Call me c r a zy
You have to do it longer...if you have no reply...dude this works ..
Or your phone is Effingham dead dude.....

Naa nothing worked...
led comes on (just for a second) when I keep pressing the power button and put in the cable to the phone.
Also I noted that when I plug in the cable a bit further than the exact slot of charging point led stays for 4-5 second then goes off.
very frustrating it has become...
HTC M8 Completely Dead
Finally I sent the M8 for hardware check and repair.
But unfortunately it was completely dead for no reason.
I left the hope and bought a new phone....
NO Solution at last...
HTC should help me out here...
There phone is completely dead... in just less than 2 years and that to with normal usage (without extreme usage)
I hope someone takes the message to htc for the problems the customers are facing from there devices..
They should just replace such devices with new one for satisfying the customers who had believed in there devices and paid premium amount for the same.

LG G4 doesn't turn on anymore ( H818N)

Hi all,
My LG G4 doesn't turn on anymore even while I am charging it..
I am actually travelling, I suspect it does come from a high voltage when I tried to charge it in a bus.
At the beggining I tried to put the battery off the phone, first the screen with logo for few seconds and after black screen. Now only black screen.
When I try to charge it , nothing happens.
1st question : do you think that a hight voltage can break any other spare parts of the phone ? Do you think the battery can be a fusible ?
Where I am , I didn t find a LG selling point so I cannot try with another battery for now.
My phone is not under warranty anymore.
Do you think that this troube can be repaired in a common repair service center ? ( not LG )
Any advice except waiting to find another battery ?
Thank you guys !

The simplist thing to do is check if the battery is charged and working. Check the serial number on the back and reply with the first 3 digits here. It is likely that you have faulty phone that needs to be fixed by LG (if it is still in warranty)
If you're sure your phone isn't a faulty model, try to enter recovery mode.
1. Hold down the power and volume down button together.
2. If the LG logo appears, continue holding the volume down button but let go of the power button for 1 second. Then hold it again.
If you get to a recovery menu, there is hope.

Thank for your reply.
With my current battery (as I still didn't have the opportunity to try to change it) , I can't even power it on (no logo even while try to enter recovery mode)
I will try with a new battery and let you know !

htc 820 is recognized Qualcomm HS-USB QDLoader 9008(COM4)

About six minths ago, my htc 820 had bricked.
When I connect the phone to wall charger or computer, it only responds blinking a orange LED.
At that time, I tried push a power button, volume - + power button and volume - + volume - + power button, but it failed.
A few days ago, I disassembled the phone cover, and I disconnect battery from the phone. I waited for a day, and I reconnect the battery to the phone. But.......... It didn't work.
Now, my htc 820 is recognized Qualcomm HS-USB QDLoader 9008(COM4). My computer even cannot recognize it correctly. Is there anything I can do to revive the phone, please.

Edit:
WOW... my phone is alive!! All i did now was:
I tried charger from my galaxy core (same amperage like htc 820 = 1A) but i used original cable from my htc charger. The led was still blinking so i decided to "knock" the back panel (around the place where connector from batterry is), then i pressed vol and vol- and power button for around 20-30s, then i pressed vol- and power button for around 30s then i released everything, then i pressed power button for 10sec and my phone turned on!!! im so happy! my phone is still on warranty but i live abroad now so i need to send it to my country to start warranty procedure but no im free of this!
Thank You guys for pushing me to try once more the magical tricks with cables, chargers and buttons
Btw.
My batterry is now 100% = that means it was charging all the time?
i don't know what was that but i am happy that it work now.
I tried this, but failed.

I tried as above. But I failed. I pressed vol+ + vol- + power button, and then released. Then I pressed vol- + power button. Then pressed power button as you quote. Was I wrong?
My htc 820 won't wake up.... and thank you for the reply.

no your case is different, showing up as Qualcomm HS-USB QDLoader 9008(COM4) means your phone has been hard bricked and I dont think there is any way to make it work again as far as I know, there is no fix for hard bricks except for some phones(not D820)
----
but if you connect charger and LED still turns on, there may be a way, take it to a repair store I guess

Thank you for your answer. I want to know what QDLoader 9008 means and you gave me a cool answer. I'll give up reviving htc 820. :crying: There are no htc service center in South Korea.
In the meantime, the phone has been connected to wall charger for 6 hours, but still orange LED blinks.
Something I am doubt about charging process, I found a charger and the phone became hotter. Why they are getting hotter?

Note II cant tutn on. Bad power ic?

Hello, please i need help. My note 2 cant turn on after rebooting. When i conect it to charge, LED charging indicator not working. Phone is completely dead. Problem is in power ic chip? Can be data restored when i replace ic chip on motherboard? On aliexpress i see for note 2 small power ic and big power ic. What is different between small and big ic? On motherboard can i found two chips - smll and big power ic?
Phone is old, but i need data on internal storage.
Many thanks for response.
Try removing the battery and charger, hold the power button for 30 seconds, then replace the battery and try charging the phone again. . Same thing just happened to me today
Thanks for your answer, i tried many tricks and i tried yout trick but its not working after 30 seconds without batery and charging, phone doesnt working phone is still dead
I would like to know too, mine gone ice cold just like that. I do remember my battery was fully charged, then the next day can't power on, no signs of charging when plugged. Did everything I can still no signs of life....
I think it is SDS (Sudden Death Syndrome)
and it is related to EMMC ( bad internal storage ) , so maybe in your case it is not IC power problem
so before you buy any thing , you should ask service person to check your phone

as far I know
when the phone (note2 ) stuck at this point (black screen)
it can be checked via power supply ( service center ) in order to test how much AMP needed to power the phone, so they can decide if it is [[ battery issue or IC power or EMMC.....or other thing
so you cannot go far and buy parts for your phone before you ( or asK) an expert

Ok thank you
by the way before you judge you can try this
in some cases ( black screen ) can be restored via JIG to access to download mode
then you can try to flash the correct firmware to your device via ODIN
