Dropped my phone, and now it randomly shut down - Xiaomi Poco F1 Questions & Answers

Hi, i accidentally dropped my phone, and the glass shattered on the top right part of the phone, now my phone randomly shut down or reboot (sometimes it takes hours, but now it reboots every 5 min approx). I don't expect to repair it, but its more for curiosity, someone has an idea of what could have possible broken?, i had disassembled it and reassembled a little, (just enough to pull the battery out). Can i disassemble the motherboard and put it back without having to reapply thermal paste?.
Anyway, i feel more and more that something is broken and not just disconnected or got loosen with the hit.
I guess im a little off topic here, with hardware problems.
Thanks in advance!

Sorry wrong thread, should be on questions and answers but dont know how to delete it xD
MOD EDIT: You cannot delete threads or posts. Thread moved to the correct place.

i have a 8125 and for some weird reason it just started fading to white screen i have tried soft and hard reseting to no avail...i also tried reflashing radio roms and wm6 roms and nothing at all? any help would be greatly appriciated thanks in advance
seriously no one as had this problem or is it that no one wants to help or did i just post it in the wrong section?
mkay, first off, not to be rude-but you waited for less than one day before whining that no-one has the answer to your problem..I say this all the time, WE ARE ALL VOLUNTEERS! BE PATIENT! Now, secondly...this has been answered MANY times, and a simple search would have provided you the answer, which is-either your LCD is starting to go out, or the small flex cable that connects it to the motherboard is loose on one end. Try opening your device and checking the flex connectors first, and if they are fine, go ahead and get you a new LCD and digitizer.

[Q] Phone acting weird post water splash...

Hey guys,
long story short....I splashed some water on my phone...had a heartbreak...put it in dry rice....worked well next day...phew!
Now, though it seems to be working fine. It has this post water symptoms.Like, it does not charge at times, shoes charging even when i remove the charger.The screen does not respond at all at times. Random restarts. I swipe one part of the screen and the other part responds...
So, in all, I am really really confused on what the hell is wrong with it.Should I put it in rice again? Probably drain out anymore water still inside?
Its been 2 days since the water fiasco. Any help would really be appreciated!!
Thanks!
holy **** .... maybe you don't need turn on until a few days to be sure to there no water inside. maybe put in rice a few more days..... but .... no promess
good luck

My Galaxy S II dropped in water and i want some help

Hello community.
I have a serious problem and i want your help.I read all the articles about dropped in water but i can't solve my problem. So i am starting from the beginning.
Yesterday my phone was dropped in the toilet for 2-3 sec (stupid i know). I took it, i remove immediately all the parts (battery, sim, external sd) and i start blow with hairdrier (mistake i know) after 2-3 hours i try to switch on the phone with no result so i continue my stupidity... I connect the phone on the charger with no result but as i noticed the back of the phone was warming. After that i read the articles (the first correct thing). So i put the phone in a rice inside a Tupperware and i wait for 8 hours. Then i start the phone and WOW it was working fine for only 10 sec. Then a battery message appear that i must charge the phone and the screen went black but the sounds and the touch was working. So i close the phone and i put it in the charger ( i know,,, i know...) After 10 min i remove the phone from the charger because was warming. I tried to switch on but the screen continue to be black and the sounds and the touch working... So i remove again everything and i put it in the rice again until today 2 hours ago.
I switch the phone and the phone started and the screen working except 1/4 of the screen in the above right place. So i close the phone and i put it in the rice again.... I noticed that when the phone is closed there is difference in colour between the black screen that working and the black part that is not working. So after again 2 hours in the rice i noticed that the black screen that is not working start to expanded in the left top side of the phone... and i am wondering, this thing is a water or something from the screen liquid?
Please help me if you can. I will appreciate your help.

I don't know if anyone can help you, it is a smelly affair.
If you were using some kind of disinfectant inside of your toilet (especially the smell of the sea or green apple) you have a huge problem.
More seriously, the layers of the screen stratify from each other. You can only replace whole screen, but I suppose that the rest of your phone also will die sooner or later.
Sell ​​it as defective. Repair will be too expensive.

Dear friend i appreciate your knowledge and i want to inform you that inside the toilet their was NOT any kind of disinfectant inside.
Any suggestion except of sell it as defective???
Okay, don't be nervous, just kidding.
No, unfortunately there is nothing you can do yourself, only replace faulty screen. You just can't stick your digitizer to screen with somekind homemade tricks. And I don't want to worry you, but I'm afraid that there will be also micro corosion on your phone motherboard.
If you really want to try to reanimate it, than you must take it apart, dry all components with rice method or better by using special adhesive liquid used in electronic to remove all wet.
If the glue from the screen has not been rinsed completly than you can try to squeeze layers by placing a book or something heavyweight and flat on top and simultaneously heat it with a hair dryer. Repet this operation few times without taking out weight.
I really doubt that this will help much but if you really wish to try than go ahead. You can always sell it after that. Even in parts.
There is somewhere on this forum instruction how to unscrew i9100 completly.
Good luck.

I will give a try.
Before try your tricks my friend i am informing you that the whole screen went black.... (Ohhhhh).
I just want to know.
The screen was broken or there is water inside the screen? (If you know)
Where car i sell the phone for parts or as a defective? (i ll give a try at ebay but if you know somewhere else give me a hint)
Thanks again guys :angel:
Theres guys on here that have went swimming with their phones and they still work.Youd only get about £130 max on eBay for the phone if you admit its water damaged.
Youd be better soaking the phone in that alcohol stuff then drying it via rice for a week.
What can you get for £130.....

I forgot the name *-) but it was a kind of copy of the iphone at that time and it had a pressure touch screen *-)
Thats all the experience I have I hope it helps

MY phone AND water:

hi every body i want to share with you my experiment when my phone fall in water:
my phone is Galaxy S II G ,after my phone has fallen in water first i get my battery out and put my phone in rice for one day
after one day in rice the work fine but after 24hours the screen didn't response to any command immediately i concoct my phone with computer
and backed up my data.
then i turned it off .
I have tried to put it in rice for to days but no result, i have tried to turn it on but no things happened i toke it to expert but he told me that the charge socket I didn't trust with what he say, so i take my phone and tried to charge the phone and the phone charged fine,then i tried to push the power bottom very hard and the phone has started working and the issue was just the power bottom ,
after the phone started the screen worked good and every thing worked fine except the power bottom and either this after three days return to work fine the issue is just left your phone to get dry.

Change the font size to normal. It looks ridiculous at whatever size it is. Most people won't even read your OP if you keep it the way it is (I still haven't read it & probably won't now even if you do change it).

[Q] Need MAJOR HELP **A PHONE FROM HELL.*

Hi guys! I'm new around here, I've been lurking the forums for the past year or 2.
I originally had a i9000. Had it rooted, flashed & running 4.2.2 Hellybean, it was a dream, easiest android phone i've ever dealt with.
Today, I bring you a device that is so mind boggling and mysterious, it's ridiculous. Before you ask, yes I've searched and searched countless hours on end & sleepless nights. Trying to work out how to PERMANENTLY fix this device.
Straight up, I'm going to tell you what I've done, what I've tried, where the phone came from, model of the phone & all the useless stuff.
OKAY. Go.
I got the Samsung Galaxy S2 (i9100T) off a friend recently, about a month or two back. He didn't have a back cover for it, and the camera was all smashed up (back camera). It was running on 4.1.2 Vodaphone Stock DVLSH. It had a few issues when the phone got to me.
I wasn't sure if the phones battery was depleted, but I had to muck around with the phone for a couple of hours just to get the damned thing to turn on.
When I had got the phone to turn on, I kept getting "Warning! Battery Disconnected!" messages, this was frustrating. I eventually let the phone fully charged before I mucked around with it and ignored the warning.
When it was fully charged, I went straight to rooting it. I first rooted it by flashing CF-Root and then flashed a custom rom. (Xylon AOKP. 4.2.2)
From here on, the phone started to randomly restart, drop signal, lose battery after random restarts, get semi boot loops.
So I flashed a different stock (XWPL8) and got rid of the Samsung Galaxy SII i9100T boot logo and it was changed to Samsung Galaxy SII i9100.
After this, I then again rooted the phone but this time a different method and used Siyah kernel and flashed Carbon rom 4.2.2.
I still encountered the same problem as Xylon 4.2.2.
So I kept reverting back to stock, re-rooting & trying again.
I've tried countless methods.
POSSIBLE HARDBRICK RECOVERY DON'T TAKE MY WORD THOUGH: I've even managed to HardBrick the device (yes I mean hardbrick, i didn't even JTAG to bring it back... I flashed Dorimax Kernel at some point and it hardbricked it to all ****.) I spent a few days trying to unbrick it when finally I just plugged it into the charged and forced it to internally turn on (i believe) and let the battery deplete (the phone was hot even when i unplugged it. So I let the battery drain.) Yes I even battery pulled and tried to reboot it to see if I could boot recovery or download or the rom even before I tried any of this! (absolutely nothing.)
I took out my SIM card after a full day of letting it drain (just to be sure) plugged it in, took out the battery while the charger was plugged in, put the battery back in, unplugged the charger while holding power, and plugged it back in and I got the charging logo booted into download mode after 80% charge and flashed stock again.
Now the problem(s) with the phone:
SEMI-BOOTLOOPS: Every time i've rooted the phone and even flashed different roms just to make sure, it does a "semi boot-loop" I've searched everywhere for people with the same problem but found nothing on it.
What it does, is it turns on (boots the samsung logo.) turns off, turns back on, turns off, turns back on etc and then after about 2-8 times of doing is usually it boots to the ROM and the phone works for awhile.
RANDOM REBOOTS: I don't get these much anymore since I found a solution where someone had just folded up a receipt and pushed the battery up against the prongs because it had about .5mm movement off the prongs. This fixed most of the random reboots and don't see many anymore.
SLEEP OF DEATH!?!?!? OR JUST A BLACK SCREEN THAT DOESN'T TURN BACK ON!?: This one I'm not 100% sure what it is, I read it's the S.O.D (Sleep of Death). Which is common on 4.0.4 and was apparently fixed in later Android versions. But sometimes, when I lock my phone, or my phone goes to sleep, the screen stays black even after I press the home button or the power button, at first I thought just restart it by battery pull or holding down power like everyone says, yeah it works, my phone boots up and does a semi-bootloop and goes back on eventually, but one day I left it on in the mysterious S.O.D. and waited 5-10 mins pressed the power button and it unlocked... This one really has me baffled and it does it a LOT.
REALLY BRIGHT SCREEN AFTER REBOOT SOMETIMES!: Okay, so sometimes when the phone finally turns on, the screen is really bright, like the brightness is still on half, but it's a lot more noticeable on how much brighter it is, it's nearly like a white.
It's really really BRIGHT. Phone shouldn't be able to look/get that bright. After a reboot though it goes away and goes back to normal but this leads me to believe something to do with the battery just a hunch.
RANDOM FREEZES!??!?: Sometimes the phone will just randomly freeze, I can be doing something and it'll just freeze, it won't turn off, I still get picture on the screen but it's frozen and I can't do anything until I either battery pull or reboot it by holding down the power button.
Before anyone asks, yes, I Factory Reset from recovery, Wipe Cache & Dalvik Cache before, I flash a new rom etc.
- My GApps matches with my Android versions each time.
- The ROMs I have flashed are compatible with my phone.
- And I've made sure everything I have done is completely compatible with my phone and android version.
What I think!:
SEMI BOOT-LOOPS:
This one, I don't think much of, it's got me baffled. It could be something to do with the Boot-Loader, could be something to do with a bad flash (but I've even tried double flashing a single rom.)
the eMMC could be damaged in a certain way that it causes these self proclaimed "semi boot-loops"
RANDOM REBOOTS:
This one, I've pretty much fixed with the help of lurking the internet over and over for hours, so this indicates a battery problem, will be replacing it this week. (Yes I'm aware that this battery problem could be causing everything else to play up and that it could all be due to the battery but can we leave the battery out of this just for now so I have more options on how to fix it.)
SLEEP OF DEATH!?!?!? OR JUST A BLACK SCREEN THAT DOESN'T TURN BACK ON!?:
I believe that this could be due to either a high load on the CPU (maybe not so much high but a really low load that it goes into a state of nothing for awhile.) It drops into a mode where it's turned off (something bigger than deep-idle.)
REALLY BRIGHT SCREEN AFTER REBOOT SOMETIMES!:
I haven't changed voltages or messed with any voltages on my phone, but I believe that it does indeed have something to do with the CPU & GPU voltages or even the BATTERY Voltages either undervolting or being to high.
RANDOM FREEZES!??!?:
I think this one is something to do with my phone not liking the voltages stock set to it.
I read that somewhere Freezing the System Alarm Clock can fix the random reboots, so I've done that and also pushed the battery up with a bit of receipt so it touches the prongs completely.
Anyway, right now, the phone is on Stock Kernel with CWM Recovery6, with PacMan's 4.3.1 Nightly release on XWLP8 Baseband and it still does this all.
I know i'm asking for a lot of help and I'm probably going to get yelled at by Devs or forum mods or some body because I've done something wrong.
But if it doesn't belong here, move it please.
IT TRULY IS A PHONE FROM HELL.
-Thanks, Just another man who wants to fix silly problems for fun.
Youve said "dont mention get a new battery".What if that is the problem.
Maybe the phone has water damage, or it needs that hawkerpaulls scripts run.
Youve just got to try free stuff, then maybe splash a bit of cash I.e battery.
Nothing software/firmware-side is fixing this. Phone has major hardware issues going on. I wouldn't bother beyond trying the 'free stuff' TheUnderling mentioned.
erm - I'm agreeing with you on this 'phone from hell!' also agree with @theunderling and @MistahBungle - it doesn't sound like its worth fixing if the free stuff doesn't work - sounds like it would probably be cheaper to buy a second hand s2! Don't think dori kernel had anything to do with your 'hard brick' - I've been running dori for some time including the experimental builds, dori tests everything himself as do his team of testers - the 'd team' and I have never known him to release anything that even soft bricks let alone hard bricks.
Good luck :cyclops:
Hey guys thanks for the speedy replies! I love waking up to instant replies!

Sorry, I was half asleep when writing all this! I am getting a new battery this week! But I wanted to have a go at trouble shooting it but crossing out the battery from the list of problems seeing as it's being replaced this week @theunderling

It may sound like it @MistahBungle but I have faith and I come down to being very patient with technology even when I do reach ticking time bomb mode. I believe I can fix it if I just get the right help !
If the new battery doesn't do anything, It might be the logic board and i'll just go buy a new one.

@Jimsilver73 It really is!
I'm not the most wealthy person or have money to just throw at things like new phones etc etc. I'd love to see what I can do on my side and try and trouble shoot every problem for even the simpilest of DIY Solutions. I get a kick out of mucking with phones and computers.
Your probably right, but I was thinking that does Dori kernel keep stock voltages or does it change the voltages at all? Because it just managed to Hardbrick its self a few hours after flashing it which was odd, which led me to suspect that my phone didn't like the Dori Kernel & Carbon Rom Combination!
@theunderling I will try that Hawkers script by the way!
Is this the one? http://forum.xda-developers.com/showthread.php?t=2100558
Phone having no back cover and camera smashed suggests that there is a physical damage to the phone, i wouldn't even try battery to this one, it may just kill the new battery if there is some kind of water damage, tho you seem like having fun trying to repair it Yes, that's hawkers script, use it and couple of ROMs, (ICS,GB etc) to see if there is a software problem. If you can dissamble it, you can check if there are some contact problems between pieces.
Hi @Dakura thanks for the reply!
The camera isn't smashed completely, but at fist I thought that the camera would be screwing up the phone in someway.
I know for sure as well that there is no water damage, and the phone was just sitting around he lost the back cover randomly after he had bought an iPhone 4S.
I can disassemble it, I just need to find my little screw driver I use for stand-off changing on PC cases.
I read somewhere that the proximity sensor has a bit to do with things, so seeing as the back cover isn't on, that maybe dust got into it while it was in his draw and that's the reason for screen-offs? because the phone is still responsive. I can receive calls & text messages just the screen is black and doesn't come back on.
The warning in 4.0.4 "Warning! Battery Disconnected!" leads me to think that in versions above 4.0.4 (4.1.2 for example) don't have warnings and the phone just turns off.
**major update**
@Dakura @theunderling @Jimsilver73 @MistahBungle
Hey guys, so I've just taken the back CASING not the cover. Off the phone.
I've been looking for breaks in solder points on the Logic Board and around it.
- The Camera ISN'T smashed it was the lens on the case..
- Looks a tad dusty.
- Semi Boot-Loops have disappeared! booted the phone with the case off and the semi boot loops are gone tried booting multiple times each time with success!
- No breaks on the logic board from what I can see as far!
- For some reason the Camera app would not connect to the Camera. "Can't connect to Camera!" maybe the camera flex cable isn't in properly.
- First boot with case off, battery gave false reading of -1021032418914 (something along those lines). That's usually caused by a lose battery correct me if I'm wrong?
- Everything seemed a lot more responsive and working.
Hmmm.
So removing the screws and taking the back casing off made the Semi Boot-Loops go away.
Maybe a part of the back casing was pushing on the Logic board and shorting it out?
Maybe the screws torque where messing with it (e.g. on a HDD with computers the simpliest change in toque on the screws in the HDD can screw the HDD.)
But the torque of the screws where very loose.
Any ideas are much appreciated!!
Yep, probably a short-circuit or dust problem or displacement somewhere around there. What you said proves that somehow the phone was physically damaged. You may need to actually disassemble all the pieces, inspect them and put them all back together, and it still may not work, for now, try cleaning the dust and tighten the screws, fasten the board.
@Dakura thanks for the help today Dakura!
Finally got around to putting everything back together after an evaluation, made the flex-cables all snug and tightened up the screws a lot!
The phone appears to be working now.
at 100% it even vibrates now when i tap things it never used to.
I couldn't quite locate the problem, but I have a feeling that one of the flex cables could have come loose but only just enough to generate fluctuation of power between full and under to keep the phone on.
Hopefully the phone stays stable!
@theunderling thanks for recommending me HawkerPauls Nuke script, I'll be using that every time I re-rom my phone from now on!
Will update the thread on a possible fix for anyone else with this problem.
It's always good to run through every possibility and solution to fix problems before going out and blowing money.
