[Q] Potential brick? Device not powering on

Hi all, i have a ZTE blade which i have rooted and flashed CM 7.0 successfully without upgrading the radio to GEN2. I've done this and much more without problems, however today for some reason the phone isnt even powering on. The only thing i did before was installing theft aware 2.0. Note that i dont have a SIM card inserted so it's unlikely that someone have sent a command that turned the phone into a... vegetable.
I tried removing the battery and trying to turn it on, nothing. I tried connecting it to the USB power charger without a battery, still nothing. This phone is supposed to be a birthday gift for my friends 30th birthday, so i'd really appriciate help getting it back to life.
Thanks in advance
EDIT: I've tried the following: with ADB devices the phone dosen't show up.
Trying entering field test mode with VOLUME DOWN + POWER key does not do anything. same result with VOLUME UP + POWER.
Tried different USB cords without success.

Have you tried holding volume up & down together along with the power button. Make sure you have the usb cable connected from the phone to a pc. So long as you have the zte drivers, it should show up in DFU mode in device manager (from what I remember).
I think from there you can flash recovery using fastboot again.

I tried that, nothing happens. Thing is, the phone dosen't give any kind of life signal at all, not even the button backlights turns on during charging. Could it be that it suffers from a hardware defect? Or is there more things i can try?

Yeah sounds like you may have a hardware issue; especially if none of the LEDs flicker on when trying the above.
hmm, ....out of ideas for now fella.

Any news on this?
I am having the exact issue, phone is like a real brick:
- Won't do anything when trying to press power and/or any other buttons one by one or at the same time
- Won't do anything with or without battery
- Won't do anything when pluging it to the USB/Charger, not even a led response
- I've tried with and without sim, with and without sd card, trie everything and still nothing, seems complketely without any kind of life inside. The only thing it does is get heat when you put it to charge with battery
I had it with cyanogen 7, max overclock to 710mhz, min arround 200, and it happened (turned off) 5 minutes after I installed Launcher Pro...
Any ideas?

I actually gave up and sent it in for service which returned me a brand new one. I suspect that ZTE dosen't have much of quality controls since a friend also suffered a case of "true-death" on her unmodified ZTE blade...

Similar issue here. If I press the power button (with or without any combination of other buttons) it just vibrates - no lights, display or sound. Doesn't power on so no fastboot/adb etc. Same behaviour with battery, charger, or both. If I hold the power button the vibration sort of pulses, a vibration every 0.75 seconds or so. I recently opened it up to get dust out from behind the screen, so no warranty :-(
Will ask at the shop what the options are for maybe paying for a repair..

Your issue is different than the one i had, you phone is at least being powered on since its vibrating.
Most likely you broke when you opened it or you simply didn't reassemble it correctly - if i were you i'd do it again and check that all the connectors are connected.
If its a software issue, you can always try TPT - total phone transfer. google it, i read it but didnt try it myself so i cant vouch for how it works.

Stupid stupid mistake!

I think I have fried my Nexus 7.... didn't even think about what I did how stupid am I....
I decided to wire up a Hella connector to a USB cable the idea being to plug it into my phone for charging on the road... I then had a not so smart idea to use my OTG cable to connect the USB A connector to my Nexus 7 to see if it worked...
Nexus 7 booted past the bootloader and then nothing.... I realised then how stupid I had just been...and still nothing...
Presumably I've run a shed load of power down one of the data line..... what a fool.....
ARGH!!!!!!! anything I can possibly do to salvage it.... please!! :crying::crying::crying:

you could try something ASUS support told me, press all buttons (volume + & -, power) for 30 seconds, and if it won't boot after that, you should get a RMA

Going the RMA route would be costly. If it is dead, he'd be better off just bring a new N7.

Thanks for the suggestion but no it hasn't worked...
I've had the N7 plugged into the charger for the last 30 minutes or so and when I went back to it the screen backlight was on slightly (you can see if you look at the screen from the side)... but the whole unit was really really hot... I've obviously disconnected it but now can't get the thing to turn off, if I hold down the power button the screen flicks off but then back on.

I would think that "broken display” units on eBay/CL probably have working mobos and batteries, as the owners are trying to dump them because of the broken screen. But, buying used is a crap shoot.
Nice that Google is selling N7s at cost (or even a loss) - but it does mean that any oem component replacements will be a significant fraction of the original price.

I was reading in Play Books when my N7 shut down due to low battery. I plugged it in and it wouldn't charge or boot and I noticed a faint light bleed and faint dots streaming from right to left on the display. I tried things like holding the power button for 30 seconds to reset, holding vol down and power to try to get to recovery, but it wouldn't take. Finally, with it plugged in, I held down the power button for just about 10 seconds and backlight and dots stopped. A few seconds later without pressing anything, it booted up. It would start to charge, but if the screen timed out, I was back to the earlier state and it wouldn't come on. So I got it started again and immediately went to developer options and checked Stay Awake while plugged in. Eventually the charge built up and I'm back to normal, at least my N7 is normal. I only mention this because the OP talked about the faint backlight and it may be worth trying.

A standard hella charger outputs 5V at 2A which is the same as your N7 original wall charger.
I doubt your problem came from the charger, it might be softbrick at an unfortunately moment.
I came across a similar problem when i was editing a custom kernel.
If you tried every method to shut down the device and failed do the following:
1. Open the case (it's quite easy to open with a plastic card)
http://www.ifixit.com/Guide/Installing+Nexus+7+Battery/9895/1
2. Unplug the battery and hold the power button 30 seconds (with the battery detached)
3. Let it soak for 10 minutes
4. Reconnect the battery and close the lid.
5. Put your nexus 7 in the wall charger, and you should see the battery bar on the screen.
After that, let it charge a few minutes and boot the device.

[Q] N4 doesnt turn on. Red Light blinks once.

Hello.
When I try to turn on my N4, I hold power button, and after about 10 seconds Red light blinks (just once, if it's connected to USB that 1 blink last for 3 seconds, if connected to wall, it's just quick 1 blink. If it not connected anywhere there is no action at all, it just stays dead, no blinks, nothing). Same if I try to go in bootloader by holding volume down+power.
This happened after I successfully installed CM12, with no errors. Then I rebooted my phone, and it just stayed black as it is now. Battery was around 25~30% that time, and phone was connected to USB.
Did I bricked my phone totally? I am now trying to charge it up already for 1 hour... but it nothing changes.
I have searched here for similar problems, but couldn't find solution...
Edit: Charging already for 10h+ , still same..
Edit2: I removed battery, reconnected after a while, still same problem.
So I tested it with multimeter, it says 2.6V, but fully charged must be 3.8V. Could this be a problem? I was charging it for whole night.
Edit3: I just got new battery . But it looks the same.. phone doesn't boot up.. same red light blinks once.. so.. its my phone is dead? I can't believe that...
When I connect to PC usb, there are unrecognized deviced called "QHSUSB_DLOAD".

easy fix
Hold down the power button and the volume down button at the same time until phone reboots. If you see the little android no need to worry just let go and wait for your device to reboot on its own. This is not a factory reset it's just like restarting your device. :good:

I have tried that many times. Nothing. It's bootloader screen, but I can't get there. Nothing happens. If I keep holding volume down+power it just keep blinking once every ~10 seconds, same if I hold just power button. If phone is not connected to charger, there are no blinks at all.

I removed battery, reconnected after a while, still same problem.

I had the same problem a year ago, I tried to remove the battery, charging all night, and other solutions that I found online and no one worked.
Finally I found here in XDA a user with the same problem and his solution was charger the phone with a wireless charger, a friend of mine has one and I put the phone to charge and after a few minutes the screen goes on and the phone was charged, then I press power button and the nexus run again.
Hope this works.
Sorry for my bad English, I'm from Spain.
Good luck.
(I bought a wireless charger in case it happen again)

I don't know anyone with wireless charger. I already ordered a new battery, and then I probably will get wireless charger also. Ty.
But this problem is very weird if you think so.. I think it happened because of many aspects together:
1) Battery was already below 30%
2) I pretty regularly charge phone with USB (won't do it again)
3) It was connected to PC USB in same time.
4) I installed CM12 ROM in same time
So main reason I think is USB, that I restarted phone while it was on pretty low battery and with USB connected.. phone restarted and got invalid voltages and couldn't even boot up or charge phone. I also found an article which says, minimum voltage, when phone battery has 0%, it's 3.0V, so I was below that.. it just screwed everything and battery died. Well, I am not sure for 100% that it's battery fault, but I hope so, I really love my N4 and still wanna use it for long time, I hope it's not dead phone, just a dead battery. Lets see! I will update this thread , when I get my new battery (less than month probably).
Sorry, my english is also not perfect. I am from Latvia.

I was playing when it happened to me. The phone was very very hot and the battery was around 70%. When I put in the wireless charged and I can reboot the phone the battery was at 65%, so it had charge but the phone won't boot.
I charge my phone almost every day, sometimes with AC, others with USB (plugging to PC) or wireless that depends of my needs
I hope you can fix it. Good luck.

Btw. Do you know if battery charges with wireless charger, if it's removed from the phone?

Don't think it does, since the receiving coils for wireless charging are located just behind the glass back.

Major Issue Google
This "Nexus SOD" issue is showing up on many sites across the Internet. I have multiple "Nexus" devices including 2 Nexus 4, 1 Nexus 5, 2 "Nexus 7 2013". It suddenly started out of the blue with one of my Nexus 4 phones. Symptoms included rapid battery discharge. I am using Lollipop 5.1 on all devices. There are many claims as to the cause, Hardware Motherboard, Power Button etc. Others claim it is "Software Related" or App Related. The problem effects Nexus 4 and Nexus 5 phones. I have ordered a new motherboard for my nexus 4 device and see if that makes a difference.
This problem should warrant a "Major Android Lollipop Crisis Team" by Google to investigate the cause and let us know what it is and what Google is doing to solve the problem before moving to announce "Android M". This issue needs to brought up and actively pursued at the upcoming "Google I/O Conference" by the strong Android Developers Groups to press for "Formal Action"

I had this problem a long time ago and my fix worked for me after doing a little research it seems like this is a case called battery total discharge. The fix was simply to charge your phone using the wall adapter that came with your phone (I still use my old apple cube wall thing) and to wait for the red light to appear then wait about ten minutes before trying to reboot.

I just got new battery . But it looks the same.. phone doesn't boot up.. same red light blinks once.. so.. its my phone is dead? I can't believe that...

I have checked all kind of videos there. Also that one. Most of these cases are related to battery, but it seems in my case it isn't. I just searched for QHSUSB_DLOAD unrecognized device, all posts says it means phone is bricked... But cmon, how? I installed CM12, successfully, without any errors, then just restarted phone, and its dead...

Did u try booting the phone without battery by connecting to wall charger and what about flashing stock ROM via PC
Also check that the power button works
This case should be solved

Just tried booting without battery, and connecting to wall. Same - red light blinks once, after I hold Power button or Power+Volume down for about 15 seconds. If I keep buttons pressed, it just repeats every ~15 seconds.
Power buttons works fine.
After I checked that Device manager thing in google.. it looks very bad.. phone is dead.. probably need to change motherboard. I am just shocked, how this could happen... I didn't receive any errors during CM12 installation. Phone just instantly died after restart.

S4 i9500 dead without reason

Dad's S4 i9500 suddenly died.
Won't turn on at all. No recovery mode, nothing.
No damage, phone is immaculate.
Was not dropped, nothing.
Phone will not charge and screen that shows charge when charging shows nothing.
Any ideas, anyone?

Double check your power supply and your usb cable. Probably the battery is totally empty and will not been charged...

I keep a few spare batteries on me that are always fully charged. We have tried a couple of those in Dad's phone, then put them in my phone to check they had charge. They had 100% charge.
The phone was still 100% dead with the 100% charge batteries in them.
I have replaced the charging port ribbon last night in case this was causing a short.
The new ribbon made no difference; still 100% dead. Nothing at all. No sign of life at all.
I'm thinking the on/off button or the power IC.
Of course it may be something else.
Your thoughts?
Thanks

It can be the power button has gone faulty it happened to me before try smacking the power button couple of times to see if it makes any difference i pushed mine against a desk a couple of times and it worked after that i installed a shake lock app so i don't need to press the power button anymore unless i need to turn on/off the device.

I put a ohm meter across the on/ off switch this evening.
I get infinite resistance when it is not pressed, and finite/ no resistance when button is pushed.
So the switch is working perfectly and it's definitely not the on/off switch.
Any other ideas?

guess your motherboard is x_x then

Yes seems to be the board.
What's the best way to work out what's wrong with it/ get it fixed.
Anyone know the most likely cause/ who does, or how to do such trouble shooting analysis.

Did you take the phone in for service? What did they do to fix it, if they fixed it... I have a dead phone and need some answers if they are out there. I'm looking through every post that has anything to do with this subject and coming up blank - just like my phone's screen!
Part of my issue is that I had a shut down from out of nowhere on NYE. I was able to bring it back up with the power, volume up, and Bixby combo the next day. Foolishly I assumed it was a fluke and went right back to using my phone just as I had before. I saw an article about disabling the Bixby button, which seemed to be the thing to do... When the phone shut down the next day again, I couldn't bring it back because I no longer have a Bixby button for the combo. It's been down since Jan. 2, and I'm at my wit's end. Can you please update your phone status? I'd appreciate it if you can!

Lol disabling the bixby button in software does not mean you can't trigger download mode. That level of software has no idea what packages you disabled ?

Did you have Substratum themes applied before updating?

Happened with me last night, bunch of updates and then black. I was gonna send to warranty, then someone told me Power + Bixby + Vl down and it worked. How can I find out what did it

When I called Samsung, they were clueless how to get it started again as we walked through all the button combinations they had. It was fully charged when it stopped working, both times. The second time it took me a few days of trying on my own, calling, Samsung and then going into their repair store.
They took it back to work on it after I explained what was going on. He tried several things and came out and told me it may need a replacement but wanted to try one more thing. Hours later, he came back and said he hooked it up to a charger and it had been dead. Once it started charging, it showed the green battery, lightning bolt and blinking circle. It still didn't start normally, but the three button combo worked at around 20%. I'm not sure if he tried before that, but it came back on.
I've discovered that my handset is extremely sensitive to cold temperatures and shuts down. I'm in the Midwest and have been working outside in a tent like structure. I listen to music, books, or podcasts while I'm working. Many times, I will put my phone on a shelf while charging but still listening. The phone shuts off and first I have to wait for it to warm up, then it has to drain the fully charged battery, and then I start charging it again. After the first time on my own, I did the button combo right after it started taking a charge and it worked.
I'm not sure if a replacement phone is the way to go, because if this is common on the S8, I might end up with another dud that would just frustrate me more. I like the phone, but this quirk is annoying.

Last night my phone was charging and accessible fine. This morning I have a green light at the top showing I assume that it's charged but the screen is totaly black. nothing I do brings up any screen. I tried all the button combos I tried plugging it in to the charger and nothing shows any kind of reaction. I tried plugging it into my computer and the computer said it was setting up device QUSB_BULK. Then said it was set up but even after it supposedly complete I could not find the device. What the hell?

S8 Black Screen
Is the green light staying on? This happened to me on one of the many shut down times I experienced. I think I narrowed it down to my phone not liking cold temperatures, but I don't know if that is your phone's issue. It hasn't happened since last winter, so I haven't needed to do any of this for quite some time, but I'm trying to remember all of the steps I took.
I'm gonna suggest getting the battery drained back down to zero. In order to drain the battery when it's black screened, I kept trying all the button combos repeatedly for, it seems like, maybe three or more days... I couldn't tell if it was dead on several of the occasions, but when I had an indication light, it went off after days of doing any and all button combos, just to drain what battery I could.
Once you do that, while keeping it out of any extreme temps, (if there have been any) then plug in the adapter that came with it, using a good quality USB-C cord and charge it again and see if the charging screen comes up. (The Fast Adapter Charger that connects with USB 3.o is the best to use. Samsung wanted me to use the original cord, but I have no idea where that is! I just used a good quality cord.)
If that doesn't do the trick, then it's not the same issue I had, and I wish you luck on finding out and getting it fixed! Don't forget to update the site for others to find out if your tricks work... (You can still try this, but it may be just to rule it out as a possibility.) Try draining it more than you first did, and then plug it in again to see if it takes a change.
If it is taking a charge again after draining and plugging in your power cord, wait until you get back up to at least 20% and then try the three button start (Bixby / Power / Volume Up at the same time) and make sure you hold them for up to 30 seconds or until it kicks on. One time, I think I held it for almost a full minute. But it did take the change, restarted on the three button combo restart, and didn't have any new issues from its down time.
If this works for you, come back and tell us! If not, come back and report what you try and what the results are.
I really hope that helps! Good luck!

Sounds like a system problem, you can try to use the button to force a reboot, if there is no response, you can try to reinstall the system, if this still can not be solved, then you may need to replace the new screen, you can go to Witrigs to see Note 8 screen, they There is an original Note 8 Super AMoled screen for sale. The price is also relatively low.
