Mate 9 bricks when restarted or powered off - Huawei Mate 9 Questions & Answers

As the title states, if I try to restart my phone or turn it off the phone will not power back up. When I plug it into my computer or wall outlet it remains unresponsive and will not charge. The only way I can get my phone booted back up is unplugging the battery and plugging it back in. The power button functions fine when the phone is on. I have already done a hard reset and that changed nothing.
I sent the device back to Huawei initially when the device was unresponsive and they sent it back claiming it was water damaged. I work in a oyster hatchery so I guess the high humidity and salt environment has done something to the phone. Have any of you experienced something like this?
Thanks

Quick update, twice in a row I have tried to open the camera app and the phone shuts down and I have to open the phone up to unplug the battery to get it to start. Im thinking that there is a short in the phone? I was taking pictures with no issues yesterday.

[Q] RIP to my Sidekick

So today, as i was on my way to work I accidentally held down the lockscreen button and the power menu popped up (I was on Glorious Overdoes V2) in the middle of a text and i pressed reboot accidentally... My phone never rebooted... It was stuck on the black Sidekick 4G/T-Mobile screen and then it would go black, then once again that screen would pop up... I removed the battery and put it back in, and without me pressing any buttons the same screen came back up... I let it sit for a while and after 20minutes nothing changed except the phone got really hot. Luckily I had my OLD Nokia in my car and popped my SIM card in it so that i could continue having a phone. I let The Sidekick sit for 4hours and it was extremely hot and then eventually it just turned off completely (Im assuming the battery drained, it was at 90% 4 hours before.) I got home, plugged it in and it wouldn't even turn on the charging screen. Somebody told me that my Motherboard is fried but I don't know. I called T-mobile and they're going to send me a new phone since it's still in the 1-year warranty period.
Anyone know if they're going to be able to inspect my old device and find out if i rooted/flashed it? because i can't get into it or anything to ODIN
I feel like they will try putting a new battery in it, and if it still wont turn on you should be fine.
It got hot because the CPU was churning over something and couldn't enter a low power state. I bet you could coax the phone into download mode and reflash it.
what do you mean coax the phone into download mode? by using the button combo to get it into download mode when turning on? I've tried that and it doesn't work. I tried rebooting into recovery and that wont work either. Also, it wont charge the battery anymore...
I've always had a hard time getting into download mode, and my phone works fine. I just spent 5 minutes trying different combinations until I got it.
I've heard people say trackpad-power button, volume down-home-power button, volume up/down-put battery in-plug in USB, etc etc etc. But the only method that works for me is to put in the battery, plug in the USB, wait for the charging screen, then hold volume down-trackpad-power, releasing power as soon as the screen goes black
You say your phone is turning on as soon as the battery is inserted? What if you have it plugged into USB first?
I had the exact same problem, I sent it into samsung and they just replaced a part(never told me which one) and it was fixed. I did noticed that when the sccreen was poped open to show the keyboard, it would stop. But it's probably a loose cable like I've read before.

Worst case scenario if you can't figure it out here on XDA, you could always sell it on eBay for parts as defective.

[Q] Phone won't charge, no LED, USB makes on/off sounds but won't recognize device

Hello! Last night, my phone died while I was out. When I got home, I plugged it into the wall charger and I noticed the LED didn't come on. I left it charging overnight for about 6 hours and tried to turn it on - no luck. I read on another topic that you needed to charge it to ~2% through USB for it to begin charging on the wall if it's "too" dead, so I left it on my laptop for an hour but again with no luck. I did notice that my laptop couldn't recognize a device though, and since my phone was the only thing plugged in, it means my phone was 'on'. I held the power button and the device disconnected, held the power button again, the unknown device reconnected. So my phone is turning on and off, so I wondered it was my screen. I turned it on, but no sounds worked when I messed with the volume button, so I'm going to rule the screen out. Despite being able to turn 'on', I can't get into recovery and it won't truly turn on.
I'm rooted and unlocked, running a version of PA, though I haven't updated it in some months and haven't downloaded anything other than a picture or two to my phone recently, so I don't think I've bricked it or anything.
I've never used ADB or fastboot or anything like that, so if there's a solution through that I'd be happy to try it out. If there's anything I forgot to mention, please tell me!
Thanks in advance for any help I can get.
This has happened to some people. It seems like going completely dead can somehow corrupt something in the firmware in rare cases.
Open Device Manager and plug in your phone, then see what pops up. If you see QHUSB_DLOAD, your phone has bricked, but it may be fixable. Check into the Unbricking Evita thread and see if the guys there can help.
Failing that, get a warranty exchange.
Try different button combinations (hold power, or hboot combination) while the phone is plugged into the wall charger. At least one person I was trying to help, got his phone to power on this way, when nothing else seemed to work.
Sounds like you're phone is in qdl mode. i second trying the unbricking thread.

[Q] Inspire 4G flashes full battery screen when plugged in, won't turn on.

I plugged my phone in last night and when I woke up today it was off. I pulled out the charging cord and held the power button with no effect. Thinking the cord may have slipped partly out and let the phone die, I plugged it back in and was greeted by the battery charging screen, showing full charge. I pressed the power button and the phone went black. On further investigation, it seems my press of the power button didn't have to do with it turning off, as whenever I plug it in it shows the full battery screen for a couple of seconds before turning off again. If I unplug it and plug it back in it just repeats this. I've reseated the battery, I've tried holding volume down and the power button, and nothing's changed the phone's behavior. The phone is completely stock, and never opened beyond the battery and card doors.
It's pretty old and I'm pretty sure I do have an upgrade available, so I'm not too upset if I have to buy a new phone, but I'd like to confirm that it is FUBAR before I go that far, and I'd like to be able to extract my data if possible. Any suggestions would be appreciated.

If you have access to another battery, you could try that, but since you're seeing the full battery symbol I'm guessing that that's not the issue. You can always recover your sdcard data by putting it in a card reader, but the phone's apps, app data, and settings may be more difficult.
Well, turns out the problem was much less serious than I thought: my charging cord has bitten the dust. I'm not sure why I've been seeing the full battery, but when I took it to the AT&T store, the person who helped me plugged it in and it started right up. I just need to get a cable that's not my years-old piece of crap that came with the phone.

Moto G turning off itself

It's a long history.
One day, my Moto G stop charging. He charge until 1%, then turn itself on, and when it was on, it wasn't charging. I thought that was a OS/software problem, but nothing was sloving. I send to warranty and there they send me back saying that a piece was oxidated and was my fault, so they can't help me. When the cellphone arrive back, it was charging normaly. I really doesn't understand. But my PC wasn't showing the smartphone when plugged in the USB port. I started to use AirDroid.
I have a little struggle to update to Android 4.4.2 but I did it. The smartphone was really weird, but I let it go. Now I have the most annoying problem. It keep turning off by itself. I don't know if is software/OS, hardware, some app, something I'm doing wrong, but it's driving me crazy.
Please guys, help =[
P.S.: Sorry my bad english.
I had same issue where it turned off on its own and wouldn't charge. I plug cable to wall charger and held power button for 1 minute nothing happened so I kept pressing power button repeatedly until it vibrated and started charging.

So, it's charging normally now, but it keeps turning off itself. Another annoying problems is that it turn itself on when I connect it in the USB port on my PC, but not when I plug on wall charger.
Sorry for the double post, but I'm don't know what to do anymore! Please, someone help me! Any ideas!
Try this
Plug it in
Hold power button for 2-3 mins
Leave it charging for an hour then unplug
Hold power button for 30 seconds it should vibrate and boot

I guess you missing the point: I CAN charge and I CAN turn it on. The problem is that the cellphone keeps turning itself off at random. Random time, in random activites.

Hi are you able to connect the phone to a PC? If so I would transfer important data and then do a factory reset to see if that solves your issue sounds more like a software problem to me.
Already did a Factory Reset (the one in Configuration, the one the Fastboot just normally boot the device) and the problem persist.
So no one can help me? =[

does the phone fades purple then goes crazy then shuts down for a while then turns back on?
It did it when I did something different, trying to turning on or recovery, I don't really remember. I remember that I freaked out, because the screen was black, without changing, than I did a reset (Power + Volume Up) and then it reseted.
You already try charging with wall charger? Maybe your PC don't have enough power to recharge this phone
I was able to charge the phone, Anyway, the device stopped to turning off alone. By itself. I didn't do anything different.
I'm so confused.
Something is shorting out inside, probably due to the said oxidation, which will most likely result in such behavior.
If you know how to do it, just open the phone, take the pcb out and clean it well with a dry contract cleaner and a hard toothbrush to remove any oxidation and possible residue.
Later I was thinking that could be it. So if anything goes wrong, I'll do it or ask to someone with a little more experience to do for me.
Thanks.

Some Moto G's do turn themselves ON when you plug in a charger, I have 2 and both do it - you connect the phone when it is turned OFF and then it turns itself on! Sometimes if I plug in the charger and turn OFF the phone quickly it stays off.
It's a bug / feature / quirk but it's unfortunately normal so you can discount that as being a problem related to your other problem.

I'm having this exact problem too. The phone is less than a month old. Twice this week its happened. Phone was close to fully charged on going to bed, I still checked some emails while it was plugged in.. the charging symbol was also on, so I know it was charging ok when I put it down... then in the morning, wake up, phone is off, but the battery display is showing 100% (The big one shown on screen when it is turned off)
Potentially if I was only using my phone as an alarm, I'd have not woken up. I always use a backup, but now this Moto G worries me!
Seems a few people are having this issue!

Bootloop + Power Menu problem

So today i started having bootloops, it was showing the Powered by Android screen for 2 seconds then booting again over and over for few hours
Now after it somehow got fixed by itself, i managed to turn the phone ON and to clear Cache
So far there are not bootloops anymore
BUT
huge BUT
the phone is poping the Power Menu most of the time, and then every touch on the screen just "presses" on the Shut Down option
If i press on the Power button myself it shut him down automatically ...
EDIT:
Would like to add, that i never unlocked it, it's the regular OTA version.
I doubt a wipe wll help, but i really wont mind if thats the case
Its almost like something pressing the Power button sometimes, but even WITHOUT the back case it still pops that power menu. even if no one is touching it at all it still pops it once in a while, which cause shut downs once in a while ...
So i woke up
The phone is off, i cant turn it on
I charge it for few hours already and still nothing happens the power button doesnt do nothing, it doesnt vibrate
So i connect it to my PC, it shows it as a Marshal something in the device manager but it KEEPS disconnecting and reconnecting every 2 seconds
I have found a "fix ur bricked phone" threads but they all using a tool that needs the phone connected to the PC, well my phone cant stay connected more than 5 seconds for some reason [ different cables, different computers] it keeps on popping in and out
Did you drop your phone in the water or something? Wet or damp from the rain maybe?
And did you try connecting it while in fastboot or recovery mode?
Maybe wet from Humidity but thats all
i cant reach fastboot nor recovery
as now it all black, not turning on not even for a bootloop
This problem happen when the phone is getting wet ? its certainly didn't but maybe i should "fix" it as a wet phone should be fixed? should i open it and dry it out? maybe take the battery out? its not that easy to take it out tho
I had a phone which was wet from the rain, it made the power button faulty. It would randomly turn screen on off like in your case. I took it to the repair shop and they cleaned the insides and it was fine again. If you're sure it's not the rain or anything then maybe that's not the reason, just a guess.
How about plugging in the charger? Does it light up? If it lit up and you cant turn it on after maybe its the power button problem.

plugging the charger doesnt do nothing
Although i got a portable charger with a led , the led turns on when i plug the One, BUT, the led bar doesnt decrease even after few hours, so its like "trying" to charge but not charging anything
Try this from OnePlus Customer Support:
2. Power cycle the One by holding the Power button for 20 seconds 5 times.
3. Attempt to start the phone by holding down the Power button along with the Volume down button to start recovery mode and performing a factory reset.

or hold Power button with the Volumn up button to see if you can get into fastboot mode.
lol bro... seriously.. you really think i didnt try that stuff before opening a thread?
I already scanned the entire web and no one with the same issue have posted a fix thread
one plus doesnt even care about their customers
Is this the guide you said you saw? http://forum.xda-developers.com/oneplus-one/general/guide-unbrick-oneplus-one-t3013732
Why not give it a try? Follow the steps and see if you are able to unbrick your phone.
I mean there's not much you can do if you can't even turn on your device in the first place :/
