Mate 30 Pro 4G blackout and won't turn on - Huawei Mate 30 Pro Questions & Answers

Hi, I bought the International unit (Malaysia certified) on December, 2019.
Today marked 2nd time (yes, actually there was first time; last week) that this unit suddenly just blackout by itself during use and never able to turn on again.
I tried to hold the power button for several minutes and also charge it and try to turn it on, I think that's the only steps I can think of try to turn it on, but to no avail.
If I just let it charge, it actually didn't take in any charges cause I have a cable that can tell if the unit is taking in any electricity (LED in blue if nothing charges, orange if the unit is charging). So, this phone is now (in this writing) behaving weirdly and it just flashes the Red battery circle (every 15 seconds or so) and the cable's LED turned to orange for just a second before become blue again, so I don't know what's going on for my unit.
FYI, I was using this phone just regularly WhatsApp (last week) when it suddenly blackout (that was like 90% battery left), I thought it was just the usual screen timed out, and to my surprise, I was unable to turn it on using the power button on several tries. Now, it was on Bluetooth playing music when it just suddenly turned off (I believe it was 70% issh battery left).
I am a bit dumbfound to find this happen to flagship phone? Does anyone have such experience?
Please enlighten me before I try to turn it on again and trying to salvage any data inside before sending for warranty (or force them to change a new one).
Thank you all for your time reading and effort for replying this.

I would contact a Huawei service center straight away, sounds like a genuine fault with the battery connection inside.

Hi,

I have to say that mobile is bought less then month ago and no modifications are made like rooting or something like that. Today it worked without any problems and when i got home i left it on my desk but two hours later i wanted to check for my e mail but screen/mobile is not turning on. I checked on/off button and it's not jammed. What else can i do considering that i can not remove the battery

Charge the phone. Could be dead. Are you SURE nothing has been modified? Also, hold down the power button until you see the capacitive buttons flashing, and don't let go until they stop flashing and the phone reboots.
Battery probably died. This phone is known to lose power abruptly. It's happened to nearly everyone at some point--it will appear to have some charge left and then suddenly drop to 0%.
Just leave it plugged in for a while and see if it revives.
nothing helped from what you mentioned but it works now. When i plugged in the charger there was no sign of charging. When i pressed and hold power button also nothing happened. Then i tried to hold volume down and power button but also no reaction from the phone and then i pressed the mobile bit harder around display to check that maybe there is no loose wire and at this point mobile turned on by itself (boot screen) and after booting there was crash report. I have HTC phones for years now and such problem never occurred to me before but phone works for now :good:
thank you
Hopefully it isn't a defect, my one x has never went off on me at a random battery percentage, except for some ROMs he he
As mentioned, some people have had instances of randomly losing charge, or phone not seeming to take a charge after running the battery down. Leaving the phone on the wall charger (not USB, which takes much longer) for several hours (overnight) and then trying to power on seems to solve the problem. One guy here could not get any response (even after charging for hours) except by holding the power button while the phone was on the charger.
The issue seems completely random. So unless it persists, probably nothing to worry about.

[Q] MotoG dead after, can't boot.

Hello,
first of all, I've read every other guide on the internet with the same problem, I haven't found a fix yet.
My problem is a little bit different then others.
A couple of days ago my phone got really hot, so I decided to stop use it so it can cool a bit. It still had like 80% battery remaining. After it was cooled down a bit it wasn't powered on anymore and I was unable to boot it up, it was just dead. I placed it in the fridge for about half an hour, after that it was working fine again.
Now I have the problem that it won't power on again. If I plug it into the wall (original charger) There is just a white LED on the front, which means the phone is too low to turn the screen on, After 2 minutes or so the white LED disappers, but the screen is not turning on. If I plug it off and on again the white LED is back on.
When the LED is gone i tried pressing some buttons according to some guides in the internet. The only result was, when I pressed the power down and the power button while the white LED is off, it just comes back on after exactly 2 minutes.
I also tried 3 different batteries, 2 of them are original motorola batteries for the MotoG, the other one a cheap ebay one.
Is there any chance I can bring it back to live? Or at least get my data recovered?
Greetings,
Lukas

Nexus 5 suddenly shut down, won't boot anymore.

Hello,
A couple of weeks ago I noticed, that the battery life on my Nexus 5 was significantly worse. I used to get about 3-4 Hours onscreen time. Now I would only get 1-2.
Sometimes when it reached 0% it did not only shut down, but it also updated all Apps on startup.
Yesterday I walked home at about 11pm and wanted to check some emails, when it suddenly went black with about 80-90% left. After arriving at home I plugged it in with my charger and it booted up again, but only to the point where you see the google colors swirl around (after the google logo). I left it plugged in the whole night.
Today I checked again, it starts to boot but after 2-3 seconds it goes black and starts again at the google logo when plugged in. When not plugged in it sometimes reaches the "Updating Apps" (or updating android something similar) but also after about 10-20 seconds it again starts at the google logo. Also trying to get into recovery mode also causes it to "reboot" to the google logo after a couple of seconds..
Has anyone experienced this before? Google search only led to a broken power button, which I don't think because I Never had problemes with the on/off switch before.
I bought the phone about 1 year ago (+2 - 3 months) from the google store, do I still have warranty? (I'm from germany and the phone is rooted and the bootloader is unlocked)
Thank you in advance and have a nice week
Did you try to enter the recovery while plugged in to a charger ? If it´s still not possible, the device might be fried.
If you´re from Germany and the device is older than 1 year, you´re out of luck. Google up what "Gewährleistung" really means and you will see that chances of obtaining a free repair are very bad
All you could do now is to try to check the phone with a charger attached to it, flash a Factory Image. Replacing the battery is not as complicated if this one is faulty.
Btw, a stuck power button can also cause a device to restart itself.

That happened to me with my Samsung Galaxy Tab 2. My problem was a haywire USB cable. And another time the charger was not of enough power (I was using my phone's charger on my tab). It used to boot up for a second or two and then switch off. Get your USB cable and charger checked.

Will do. Thanks for the help
If anyone else has other ideas I'd be glad to her them
If you can use another phone I'd recommend "ampere" tho check your charger and cable.

G Flex 2 keeps shutting down

I recently dropped my phone on the ground and the glass is now broken. But it worked normally for about 14 days. Then suddenly one day at work it shut down on its own. After that I wasn't able to start it. No reaction for any of the buttons, nor their combinations. Even when I plugged the charger in, no sign of life. I thought it's over.
Then the next day, I plugged the charger in and the screen with 0% battery appeared. So I left it charging, but when I came back to it (20 minutes) it was dead again. Not even the diode indicating it is charging. Again no response for the buttons, nothing. So I tried to disassemble it, disconnected everything. Put it together and viola! The screen indicating 0% battery was there again. I left it like that for a while, and when it was charged a little, I tried to start it. It started and normally worked. At least it seemed to, but after a while (1 - 3 minutes) while I was using it, it went to the dead phone again.
So I discovered, that when I disconnect the battery for a while and then connect it again, I am able to boot the phone. I was even able to do factory reset. I thought I got it and that it was some software fault. However after like 5 minutes (it downloaded all apps, logged to my google account, looked all ok) the screen shut down again and again the phone played dead.
Now I have the phone booted, and charging (almost 100% now). But I guess when I start using it again, it will again go to the dead mode (since it did it everytime after I used it a little, no specific action done, totally random).
I guess it has to be related to the broken glass. Maybe some water or humidity got through it and the phone is trying to save itself from damage by going to the dead mode. It's weird because sometimes (like now) the phone is OK when not used, normally chraging and not shutting down (now it's ON for about 40 minutes), but if it shuts down, it takes about 3 or 4 battery disconnect and connect again, before it boots to the main screen. Sometimes it just dies before the screen, sometimes it dies when I try to plug the charger in, really no idea what causes it.
How should I diagnose it? USB debugging and check the log when using it and when it dies? Or has anyone experienced this too? Or could the battery be damaged? Or can I somewhere set the phone to prevent from selfkilling actions? Today I will try my main board in my friends G Flex 2, to see if it's the board, or something else.

Adding the error log from console
OK so it was probably mother board fault, so I had to buy a new phone It is like 3 months, and I just yesterday accidentally poured some water on it, so i destroyed another one. It is still in warranty but I guess with water damage there is no warranty. Anyone knows where to find all the water damage indicators? Or is it even possible to make it look like there was no water damage?

Red Blink Errors - No Screen

So I have no idea what's going on with my phone:
It consists of 3-4 sucessive red LED flashes, can see a charge icon on the screen for like 0.25 ms (literally haha), and then it shuts off and this process just repeats.. any idea what is going on?
I've attached the video here: https://youtu.be/rnW2euEdKaE
If it matters: The screen was cracked, and subsequently replaced, but that was some time ago..
Hi,
Did you try another charger ?
Definatly for some service

I was having the same issue... Try holding the power button for 10-20 seconds too and see if that brings it out of its coma...it helps with my phone
Hey all, thanks for the suggestions.
1. I tried different charger, in fact 3 different ones.. still nothing
2. Service? What kind of service?
3. I held power down, it gets to the huawei splash screen, for again.. 1 sec than restarts
Any other suggestions, thanks!
I don't know if it's exactly the same thing, but perhaps Is this a way to make your phone working again

Tried that, took the battery out, plugged it in.. no more flashing red LED.. i see the huawei screen now, but it boot loops. If I insert the battery in while its plugged in like the above, than it does that led flash, and no screen.. so i'm thinking bad battery??
It's certainly the battery,
Last time your phone was working, did you use all the battery (until 0% and then power off by itself ? )
You can search a new battery on the Internet,
With the Model code at the top of it, you will find easily a new replacement battery)
If your battery goes under a certain level of charge, ie close to 0%, it's possible the onboard security prevent it to charge normally.
You can try the freezer trick, it helped me to recover an ipad with the same condition.
-Put your phone in a ziplock bag to prevent frosting and humidity.
-Let it rest at least 1h in the freezer
-As soon as you get it out of the freezer, plug it in a wall charger and wait at least 15 min before turning it on.
You should claim your warranty, contact your vendor.

I don't believe so, Its my backup phone so there is potential the battery would have hit 0% as I don't frequently use/charge it..

Hi there.
Did you managed to fix that? I have same problem. I just replaced screen with new one.
Firstly I connected new screen to motherboard and it worked perfectly. I put it all together, glued new screen to frame, connected flex'es to mobo and... nothing. Red light blinks, and screen flashes with "HONOR powered by Android" screen if I disconnect battery and just plug to usb.
Battery is not a problem, before repair it had about 70%, and now it's voltage is around 4,05V.
Any ideas?
same thing was happening to my huawie honor 8 for some time now... i brought a new screen n that didn't fix the problem ,,,,, the person that fixed the screen for me said it needed a power boost( or something to that extent) n in like a hr or so after not being able to start just the screen blinking it came on!!!!!!! i was ecstatic tbh... sadly like a week n a half- a month later the **** stopped working again ... the red light comes on when it charges n every thing but the screen doesn't fully respond just stays blank. i definitely think its a battery problem but not too sure
