My Mi A1 has fallen into the water and is now experiencing a major problem - Xiaomi Mi A1 Questions & Answers

Unfortunately, my Mi A1 dropped in water. I put it inside a box with silica for 48h and it come back to life. ( I'm sorry for the bad english, i'm brazilian). However, I have a problem that is bothering me.. when the mi A1 is charging (almost when it is in 85%) the phone starts to bug, sometimes the mesage 'interf sist stopped' appears on the screen, and my phone stops working. Fell minutes later it turn on and work fine but the max battery is 84%.
Could I do someting about it?
Please someone help me ! (in Brazil do not exist a technical assistance from xiaomi):crying:

I already did it. Nothing different happened.

I wouldn't recommend opening your phone on your own.
The best thing you can do is dont let the temperature of your phone increase. Keep it in rice/silica every night. Don't let it charge over 50%.
Once all the moisture is gone it will work normally again (hopefully).

Even I had the same issue..
Just place Ur phone inside a car then put the car in sunlight.
Let it bake for 3 hrs
Remember to keep the phone off
Hopefully it helps..
It worked for me.

i wouldnt do that, you will most likely damage permanently your battery
i would open it up and "dissassembly", i mean, disconnect the main components and put it all together in silica/rice or whatever for a deeper drying
i think you can not do more

Thanks for the answer. Put the main board into isopropyl alcohol is a good thing to do?

i dont have any idea, sorry, but you can google for any guide talking about tips for drowned phones, all are the same

Today I tryed a thing .. I let him charge and put his screen to be on all time, and I see the screen freezing, but when put the charger off after some seconds it comes back to life. I'm very angry about it, nobody has an idea to solve it?

Faça como falaram e deixe ele esquentar desligado. Formate ele para configurações de fábrica e tente de novo ver se carrega.

Don't do that.
There's moisture in your phone. heat will expand it and it will spread. Keep it at normal temperature and periodically in moisture absorbing material. That's the best thing you can do.

hardwarre problem on wing

so i think my wing may be in the process of biting the big one. A few days ago, my wing restarted itself for no reason, i figured it was probably a system error and didnt think twice about it. Now all of a sudden my wing will constantly restart, sometimes in the middle of a call. Sometimes when it does restart the screen will either turn white or fade to white. I reinstalled the original rom to see if it was a software issue and it is still doing it. Also, it doesnt normally do it when it is just sitting there, and sometimes i cant turn it back on. Any ideas?
Make sure the battery isn't loose inside the case... and that all the prongs are making contact.
For the life of me, i cant figure it out. I know it has to have something to do with the phone not getting power. At this point, it wont even fully turn on. Short of taking it apart and checking the solder, does anyone have any ideas?

If you already reflashed the original rom, and it is still doing it, that tells you it is definitely a hardware issue. It does sound like it's losing power which could be a host of things. (loose battery, defective battery, loose solder on board, etc) I would try what duprade said, and check to make sure your battery has a good connection first. If you had a friend that had a wing as well, you could try his to make sure it's not the battery.

Brand new battery (free from tmo to replace the dynapack) Everything on the mainboard looks like it is soldered well. There is an internal watch batter though, could that have something to do with it?

I doubt it. I would guess that's the cmos battery. If that were to go, then your phone wouldn't keep time, but that wouldn't stop your phone from functioning. (I used to work in the service center at a computer store).
maybe its the processor then. sometimes, after it freezes, it artifacts before shutting off

There is the possibility of you overclocking your phone, and it heated up and could have burned or cracked some solder. It might even be overheating and that's why it reboots. At any rate, it def. sounds like hardware though. Sorry man. You could try to resolder the connections on the board just to make sure, but it sounds like you have a paperweight. Is it under warranty or do you have insurance?
only ever oc'd once, for a few minutes, and not very high (like 267 i think) It's on right now on the power cable (this wouldnt work yesterday) I honestly have no fricken clue whats going on with it.
Is it possible for the battery to completely diminish itself without being used for a day? Before it died on me last, it had a full battery, now it is showing 1% (and charging).
By the way, as I stated above, it is a brand new battery sent to me by tmo.
Dang it all! Stupid thing just shut off again... ARG!!!

Hey dcmtnbkr. I seem to have the exact same problem with my Wing. It shuts off for no reason, and it does it absolutely randomly. Sometimes it would work for 3hrs straight no matter what i use it for. And other times it shuts off every 30sec. and it takes 3 to 10 tries to turn it back on(most of the times it would not get past the windows mobile welcome screen). I was gonna flash it with the newer Rom, but i'm afraid that the damn thing might shut off during flashing . So i'm stuck. If you find the way to fix it - please let me know.
actually, i just talked to tmo, and apparantly NOW after i told them I'm cancelling when my contract is up, now they can apparantly cover it under manufacturer warranty (as opposed to the last time i called about a week ago) I would call them even if you didnt buy it from them, tell them you dont remember where you bought it, but it was some company online. These phone's arent that old and you may still be under the manufacturers warranty. Also, i would try and flash it back to the original. These phones are very hard to brick, and i would ask around to see if a powerdown in the middle of an upgrade would do it. I just got mine to reflash without a problem.
my wing rstarts itself wen i jus tap the back of it where the battery cover is but it wont restart everytime. anyone have any ides?

Death HTC 8525

My 8525 does not turn on anymore, changed battery several times, let it under charge 2 days, no sign of life in there....should I trow it away or is there hope? Help please I am LOST without it!!!
Try chargin the phone without the battery for about 20 minutes and then insert the battery to see if it'll sprint to life. If not, try a differen outlet or charger. If all fails, don't throw it away, it's not that useless.
Thanks I trying that now,but I do not see any led turning on...keeping fingers crossed!
Were there any other symptoms before hand? Had you had it hooked up to your comp recently before that? Hard reset? Check how snug it meets the gold contacts. Ive seen situations where they get spaced just enough where it wont make contact. Check battery and contacts for buildup (happens over time. had this SAME heartattack awhile back with mine ) Lemme know if you need more help.

Hello Black Joker
what do you mean by "buildup"?
1Hard resetted a couple of days before (I am a ROMburner junky
2Turned itself out a couple of times before...
3When I do not use it I always keep it in the craddel hooked up with pc...
All I know is that I replaced the micro SD, put it down and when I pick it up 2minutes later it was death...
Now is under charge without battery...will report later...sig...
By buildup I am referring to this black looking stuff on the gold contacts. It happens over time. Another thing you might try is a different battery. Ive seen em on eBay for a few bucks or try a buddies battery if you know someone w a similar phone. If thats not an option some local cellphone store may have one u can try to see if she comes on. If all else fails, PM me. I would be more than happy to see what else I could do.
I did try everything but no way to wake "her" up...I have sento you a PM black-joker...
Its possible there may have been a surge that fried the internal fuse. That would account for it working then suddenly not with no LED response.
Check out Mike Channon's post for a link to his website, you'll find more info there...
Good luck...
Happy New Year to All..just came back...
Backy to my sorrow..could not find any solution jet!...

[Q] Dead HTC HD2 (Why? Don't know - explanation inside)

Hi
I was playing an android game, can't remember wich one, when suddenly my HTC HD2 turned unresponsive (bloqued), so I removed the battery and powered it on again. When I did this, the bootloader opened but it seemed bloqued too, no android message, no bootloader opening, anything... And once again, I turned it off and powered on but now without any response, completly dead (Only a small vibration, diferent to the one when it power on. [equal like the one previous to the boot one, I don't know how to explain])... No charge led, no bootloader, no tricolor, but without any flash or something similar (Like most posts I have read)
Anyone knows how to fix it?
My htc is a HTC HD7 T-Mobile with MAGLDR (last version) and android 4.0.4 completly working before this
Thank you!
You mean you have an HD2 with MAGLDR, WP on NAND and ICS on SD, right?
First thing to check is the battery pins, easily bent after a battery pull. Make sure they are straight and make contact with the battery. Second thing, are you sure the battery has enough juice? It could be just an unfortunately-timed run out of juice.
If above is all checked, was the phone running hot (like .. HOT) prior to the freezing?
Thanks

Thanks for your answer!
Not sure of the battery juice, I will try to charge it with a broken USB, directly with the cable or with another battery.
Pins seems to be OK, but I don't know. When the phone turned off I was only playing a 2D game ,for no more than five minutes, so I don't belive that it might be hot.
Some unsuccessful attempts
Okey, i tried to charge the battery with the usb but it does not work, so I tried to boot the phone using directly a 3.5 batery (similar to the 3.7 Output of the battery) and it does not work too... The mobile is completly unresponsive, the same vibration in the begining but nothing later..
Thank you!

Well, this is weird. ................. I recall seeing a similar problem somewhere around here, but I don't know if it was fixed or not. Even if it were, I don't know how we're supposed to look for it.
You can try some basic stuff like :
- Changing the battery *try to use an HD2 one*
- Try removing the battery, sim and sd card. Leave them out for a few units time and put in the battery back and try it again.
You can try your luck and search the hd2 (you can use the link in my sig) fora with potential keywords..
.. I can't think of anything else ... I'm sorry.
More of it sounds like BGA failure. Did your phone got hot while playing games?
Also what settings on CPU were set?(freq and voltage)

I have already asked him about that and he said "When the phone turned off I was only playing a 2D game ,for no more than five minutes, so I don't belive that it might be hot."
One more thing you can try, put the device in a sealed bag and put it in the freezer for about ten minutes. Then try to boot it up into bootloader (boot up while holding volume down). If it boots, then it's 99% the infamous overheating issue.
Report back.

It is widely known that putting an HD2 with a faulty mainboard in a freezer for a few minutes will make it more likely to boot up (before it freezes or restarts again).
I don't know *why* this happens, I just know that it does. If you are not convinced, please do your own research
I do know how does BGA fail, and putting your phone in freezer WON'T do any good. It can only worsen the fate of phone, further damaging board or battery.
With all respect, don't give advice if you don't know what are you doing.
Anyway.
If you got warranty - RMA
If not, get infrared soldering station or look for one. Resoldering BGA(ball grid array-micro soldering points) on motherboard could help - CPU BGA tend to get loose sometimes. It's just the way it was designed.
Otherwise, if failed, replace mainboard.
That's it.

How can you be so sure it is faulty BGA as to start saying use this and use that?
I did not say the freezer will fix the problem, I just said it will help us identify it!
And to reply to the "won't do any good", here are two examples OF MANY:

@op An advice: don't do any of the IR soldering mentioned above or even open the device until you are certain it's the mainboard.

Because that's the symptoms of faulty BGA. System stop. Different vibration pattern and bootloader lockout. If memory failed, it's on motherboard. If CPU failed it's also on motherboard.

How in the world does freezing help identify motherboard fault? It's just nonsense.
Freezer trick can help identify BGA contact issues as the cooler temp contracts the CPU & can temporary cause the the solder points of the ball grid to contact and also keeps it cooler for longer sometimes allowing for longer run time or boot progress.
You are not freezing the device to -20 just simply quickly getting the device cool.
Done it myself to more than one hd2 & is a useful diagnostic prior to buying & swapping a mainboard or getting a current one reworked.
Okey, I tried again and nothing happened. I will call to HTC tomorrow and ask for a diagnostic (And price of repair...). I will coment it here as soon as I'll know something. Thank all of you for the help

Wait, is it a bad thing if the touchscreen does random stuff only when you try to use it whilat charging on a different brick?
I use a Sony Xperia Z3 brick to charge the phone more slowly...
I remember it does adjust and then work flawlessly, but honestly I can't say this happens everytime with 100% confidence as I don't really use it while charging.
ONLY while charging, don't know about original brick.

From my own expirience i can safely say, that while charging the touchscreen does react more slowly and it does some random stuff. I would say that it is some isue in device construction as when i tried to meassure voltage on devices metal frame i was able to measure around 600mV on it. I am always using original charger and the same thing was also happening on my previous Mi A1. Also if you are charging a phone and you rub your finger litly on its metal frame you can feel a small vibration (due to the voltage on it.)
