Mi A2 impossible to wake up - Xiaomi Mi A2 / 6X Guides, News, & Discussion

I recently encountered big trouble when unlockin m'y A2.
When in deep sleep mode, pressing touch ID and power Burton didn't wake UP the phone. The only way to unlock was to plug a charger in usbc port.
I finally rémind that it occured since I dropped some water on it 6 months ago.
One week ago, I finally sprayed contact cleaner in the usbc port and MIRACLE, EVERYTHING WORKS FINE

[Q] Meizu mx5 new wont charge and startup

Hello dear Forum members,
ive brought a new geniue Mx5 phone.
the phone worked perfectly for a couple of days.
yesterday i forgot to charge it and it completly drained its battery.
in the morning i connected the phone with its original charger and cable and nothing happens.
the phone wont charge and wont start, i've tried different chargers and cables and even connecting it to my comp via USB and still nothing happens..
theres only a led notification light blinking, the phone and the charger are COLD even after a couple of hours connected to the charger..
i also tried to remove the simcard and enter the recovory mode ( tired pushing the volume buttons [+ and -] with the power button, and all the possible combinations and yet nothing...)
i didnt drop the phone and didnt put it under extreme wheater....
what can i do ?
i'd be very thankful to have your advice and ideas
yours,
Elitemagix
Hello!
Have you tried to let the phone charging some hours? When the battery is fully drained you need to do this

hey iicc thank you for the reply,
after i read your comment i charged the phone for the whole night, and still in the morning nothing happened the notification light is still blinking and the phone is cold
any other ideas???
Ive had the exact same problem, just ordered the phone came today... let it die then charged and now its not charging! I don't know what to do! Did you find a solution?
Hi, I've the same problem with a Meizu MX3. Have you found any solution?
Hold power till stops blinking, should just boot after that.
hi i have this problem too has anyone fixed it ?
I had and have the same issue with my Meizu MX4, with the Ubuntu Touch (OTA-14) OS.
I have changed battery and connector and the problem still remains.
Taking out the battery and charging it externally works, but charging it through the connector and micro-USB plug does not work.
As I suppose other people higher up in this thread have Flyme as OS, it seems to be a motherboard issue to me.
Any solutions found meanwhile?
Since I don't have the necessary equipment at home to perform the external charging, and I have so far relied two times on a repair shop to do so, I would also be interested to get references of universal or Meizu specific external charging equipment.
Thanks.
I had the same problem with my meizu m5c
Idont know if it will work on your meizu models bu i fixed my by just pressing the volume up and power button then it showed “battery lower than 25%,update available” then i pressed restart and placed it on my charger and it was fixed

"Moisture detected" Bug Causing Charging & VR Issues

So I've had my phone for just over 2 weeks meaning unfortunately, I can't go into Verizon for a quick exchange. So I'm not sure if this is a hardware bug that I should be worried about in the future, but ever since I was playing with my gear VR a few days ago my phone randomly enters VR mode. The display goes max brightness, screen goes all black, little "x" on the corner pops up. Another issue I'm facing is it sometimes gives the moisture detected error and doesn't let me charge my phone normally. Luckily I have a wireless charger, and I was able to get the fast charger to work when I got home. I also put it in some rice for the last two hours before going to work.
My main issue is, I haven't actually gotten the phone wet and this problem started a few days ago when I first setup my gear VR. If it somehow got wet could it stay wet for almost 3 days before giving me the "moisture detected" popup?
Oddly, I had exactly the same problem with mine, it hadn't been wet recently, but started flicking between Fast Charge, Cable Charge and refusing to charge at all with a Moisture Detected warning. Only wireless charging would work. I didn't try plugging into GearVR but I did try to connect the phone to my PC via USB and that didn't work either. This started about 9 days ago, got progressively worse.
I'm not sure what has fixed it (fingers crossed) but I tried two things the morning before it sorted itself out. I blew a hairdryer into the usb port on the cool setting for a few minutes, not enough to heat the phone up but I thought it was worth a try to get rid of any moisture that might have gotten in there. I also reset my Google advertising ID, as I'd been having problems with dodgy "virus warning" adware popups in Chrome and the stock Samsung browsers, even after a factory reset and a Malwarebytes scan. The popups stopped, at roughly the same time the USB charging started working again. I'm not saying it's linked, it might just be a coincidence that the moisture sensor started working at the same time I reset my ad ID, I don't know enough about malware to know if it could mess with the phone's moisture lock software. Possibly the hairdryer has dried some moisture or blown out some residue but it didn't start working until several hours after I tried that, but only a few minutes after the ID reset. Might be worth shot trying both?
NB occasionally when I plugged the charger int he screen would go black with a little white 'x' in the lower corner which switched sides a few times before the moisture warning popped up. That sounds similar to your issue with VR.
I had this issue as well. I used a set of tweezers to slightly push up on the plastic piece that holds the contacts inside the charge port and also lightly scraped the contacts with the tweezers to remove and possible corrosion on them. it seemed to work for me. I would caution anybody who is willing to try this to be very gentle and careful while trying this. this is just what worked for me
Had the same problem with brand new galaxy S8. Turned out to be the car charger. No problem on home charger. Had a spare car charger and problem went away.

Phone Just Died

So earlier this week, I was using my phone with Google Maps like usual. I plugged in my vehicle USB port to the phone to save battery. I had +50% on the phone and 1A USB port. So after like 5 minutes of it being plugged in, my phone just turned off. I tried turning it back on and all I get is the boot screen, then AXON shows, and puff... Phone off again. I tried booting into recovery but phone turns off before TWRP finishes loading. Phone doesn't seem to be charging. Tried different cables and charger to charge phone but nothing. No charge light. Seems like battery is dead because the phone turns off during boot and battery not charging.
Nothing seems shorted. Phone been working great for weeks before this. BL unlocked, Debloated stock, TWRP. Any ideas other than sending back for warranty? Luckily I still have my S7 as primary but I had my Axon for primary for my trip for real world daily use. Needles to say, photos and videos are wanted off the phone.

Have you tried going to bootloader mode by holding power and volume down
If the battery has died, then the phone wouldn't turn on is my thinking as everyone you then it on it eats some vattwry
You didn't mention specifically, but have you tried using the factory wall charger & cable and leave charge for like an hour?

Original charger but with certified Micro-b/USB-C cable I've been using for weeks between my S7 and the Axon.
So I left the phone alone for the last few days as I was busy at work and Just didn't feel like messing with it when I got home. I tried to turn the phone on but battery was dead. The quick flash of red led was the indicator trying to power it up. So I used my Samsung charger as it was right there and the original ZTE cable. Phone lights up charging and so I left it as is to go to work. I get home, the green led is lit, so I'm hoping my phone will power up now. Nope, right back to my original issue. Power on phone, gets to Axon logo then eventually turns off or goes black screen. I tried booting into recovery but turns off before fully loading. I try to charge phone again but no led indicator.
So later today, I'm going to try to boot into fastboot and try the new TWRP recovery. Maybe it was enabling r/w on system that caused this. I had downgraded to unlock bootloader and then installed ZADmix. I've been usuing it nonstop for 2 weeks with no issues. I have xposed installed so I know rebooted a few times to get everything working and it never turned off since then.
Really frustrating as that's the phone that had my pictures on it.
Hi @RoninBlackSoul, so what did you end up do ? Have you found any way to bring back the Axon from the dead or sent it back to ZTE for repair / replacement ? Same thing just happened to me, and for me Axon 7 is my primary phone ... if the phone is really dead ... will neve buy another ZTE phone ever !!!

Honestly not sure what did it. After battery drained, plugged it in to charge for 2 or 3 days. Then remembered some note about enabling write access in TWRP (something like that) would cause bootloops. Which is weird, rebooted the phone a few times when it was working.
Any case, I reflahed the recovery/bootstack in EDL and got my phone back. Been working great 5 months now

@RoninBlackSoul, thanks for the feedback.
Got mine working also, my phone was not charging at all. After suddenly rebooting and battery went dead fast, phone was not able to charge for about two days. After which, suddenly started working again, was able to charge and works normally now. This is weird. From my point of view this could be: 1. some sort of auto-protection perhaps or 2. an actual hardware design issue that manifests at random (for some after few weeks or months after purchase). For the 1 point: I was using a non original cable using the original charger, and the USB type c plug was hot at the time the issue occurred. Perhaps due to that heat some protection mechanism manifested that got reset after phone was completely out of juice. Will use only original cable with the Original Fast Charger from now on, as the usb-c plug of the 3rd party cable was fine with a normal charger (non QC3). Hope issue will not manifest again or, Axon 7 will be my last ZTE device ...

I only use good chargers rated for QC or 2/2.4 amps like samsung, anker, aukey. Haven't had issues since. Plus certified type-c cables at all times

Help! Battery drained, phone won't turn on, battery charging icon flashes on and off?

My phone had been working perfectly fine, as well as charging perfectly fine. Recently, I accidentally let it drop to 0%, which I don't usually do. I went to plug it into the same wall outlet as always, but instead of the usual charge process, the battery icon with the lightning bolt in the middle simply flashes on the screen and then turns off, which happens over and over again.
It should be noted as well that about 3 weeks ago my phone get fairly wet. After that incident, I turned it off till it dried, powered it up, and everything appeared to be totally ok. No problems since then until this.
Other facts:
-I can safely get into the recovery menu (power + vol down), which is stable, but any menu selections result in the Motorola splash screen for a quick second and then the phone powering down.
-The computer will recognize the connection to the phone.
Attempts to resolve:
-New cable, new usb hub, new wall outlet
-Trickle charge from the computer (same flashing)
-Phone in rice to remove moisture
-Toothbrush cleaning of Micro-usb port (suggestion from another thread)
I'm pulling my hair out, and I am considering prying off the back and replacing the battery. I have searched other threads, but have seen various solutions none of which worked for me. If anybody has any idea how I can fix this please help!!!
Thanks in advance.
Unfortunately most probably is the hardware problem. I had similar issue with razr. Splashed it on the beach, quickly washed with tap water, dryed it and for couple of days like nothing happened. Then suddenly digizer stopped working. It was motherboard. Luckily one xda member donated me the same phone with broken screen so I replaced motherboard by myself.

Thanks for the suggestion. Well, I got it back working again, by charging it for 5 hours straight and then not charging it for an hour. Now it appears to be functioning alright, with the exception that it once went from 40% bat to 15% to 0% in a matter of seconds and I had to repeat the procedure to get it back on. I have another turbo with a broken digi that I could cannibalize but I have no idea what to replace... the battery? Bizarre issue, but I guess that comes with the territory of water damage.
Maybe some part is still wet. If another Turbo has only broken screen, then is probably the easiest solution to take screen from the (ex)wet and put to another one. You just have to have proper screwdriver.
Replaced battery now Droid turbo flashing when I charge?

Xiaomi Mi 9t completely dead(?)

Last night I've put my Mi 9t to charge and went to sleep. When I woke up, the phone was turned off.
I've tried to restart it and also pressed the volume + power button combinations to force the recovery mode - unsuccessfully.
No blinking lights, no MIUI entry, no vibration, zero response from the phone. (Is it bricked?)
I've started to research and since my computer can't find the Mi 9t (running Windows 10) the only solution seems that to disassemble it and do the EDL Mode Test Point, to acess the recovery mode and try to flash the phone.
Do you have other sugestions to try?

This is weird. Maybe it's not charged? Did you try another charger and/or cable? How can the phone get bricked overnight by doing nothing? Never heard of it.

I've tried today during all day with a different charger, no response.
It's the first time a thing like this happened to me as well. I've never flashed it before or did any major modifications. I was running MIUI 11 still.
If the battery runned out how can I revive it?
On another forum a user told me it could be the integrated circuit broken or a battery problem.

Then I really don't know. Like I've said, never encountered this before. You could try going to a repair service.
you could open backcover and charge battery directly to see if thats usb problem
You can make an EDL cable. is very easy to do and you have a lot of videos and pictures about it.
Dont worry if you have to open the phone is really really easy. With a hot air gun or a hair dryer you can do it in 2 minutes. You are going to need also a piece of radiography to separate the cover
Then the test point is really easy to do it, check some pictures in google, also you can check the usb port if it is damaged or not once the phone is opened, but of course if the phone stoped working from day to night is weird a usb faulty port
Pls don't open anything or try an trick. Just take it to a repair service so u don't make things worse
I've tried the test point and didn't work, as well
So I took it to a repair shop that accepts xiaomi. They are going to order a new battery and a battery connector (2-3 Weeks).
I'll post when I'll get more updates.
I had a lg g3 that did the same thing. Charged it over night and it didn't work the next morning, could be power surge. Ever since then I never charge my phone over night
So, I've picked it from the repair shop and they couldn't fix it. They changed the battery, the battery connector and the display. They said they don't have a solution for the phone.
My next step is to contact gearbest to see if they have a solution for me.
