Phone stop and won't turn on - Xiaomi Redmi 4a Questions & Answers

Hello,
I have a Redmi 4A with RedFox as Recovery and Pixel Experience ROM randomly the phone turn off and then it won't turn on anymore with power button and won't charge neither.
Only way for it to came back to life is to disconnect the motherboard from the battery and to plug it back.
Then it turns on normally.
Any idea where it can came from?
Regards,

Probably a dying motherboard. It happened to me twice before and the solution that worked for me was to charge it via PC/laptop and wait a few hours.

OK, thanks I will try but it seems it won't last long.

CM9 My Optimus wont turn on

Hello Pleashe help!
I have installed cm9, and for the night plug it in the charger, and now it wont turn on! It's plugged to the charger but nothing is working! Please Help! I cant turn it on! SO many thanks to helpers! Please guys!
I'll be so glad if you help me!
Have you tried a battery pull and then turned it on again? It could be a BSOD.
had the same problem (sort of) yesterday without the powercable connected, it seemed like the battery was empty while it shouldn't be, i fixed it using power+ vol up but i guess a battery pull should work aswell
sent from my LG 2X using cm9
Well i have tried for 5-10 mins to fix it, plugging it on the charger, and pulling the battery, this morning, but i can't get anything. What can be that for?
Can i revert back to stock (nVflash), or even turn it on? MUCH much thanks to everyone!
I really want to get my phone working, If someone can help me, i can give him some money in PayPal!
P.S I'm in school now, and with another phone! When I go back home i'll try what you say again! I left it in charge (from pc) and hopefully, it's because battery has drained or something! Thank you for the replies! I look forward to reply's, about how to solve this. Thanks!
had same problem this morning (left phone in charger for night).... i just disconnected phone from charger, removed battery for 10 sec, put it back - and phone is on...
only problem is that battery level was showing 999% (unknown), and after ~10-20 minutes it was 1% all the time (worked with 1% 2+ hours).. now it is charging again.. everything seems ok.
**
If it wont turn on, just remove battery, and connect it to PC while holding volume up key (or down.)... it should boot "upgrading firmware" mode... after just use smartflash and restore to stock.
hm... happend second time, when phone was on "wall" charger..
when charging from PC - no problems... when from "wall" charger - always BSOD after few hours...
anyone else have similiar problems?
I had the same as in OP during first night while it was hanging off the wall charger. It hasn't happened since, but I enabled "keep screen awake during chargin". I beleive I read somewhere here it should help with that.
Same problem here overnight charge and the phone wash dead.
After a battery pull it was ok.
It 's a bugg.
Mine survived overnight charging just fine...
And it rocks (ICS i mean).
Solution for Me
Hey i got my optimus 2x just yesterday on Starhub Singapore, and similarly, i HAD the same problem until i followed some post above about removing the battery, plug in the computer/laptop with proprietary usb cables, WHILST HOLDING THE VOLUME UP AND POWER BUTTON TOGETHER. Hold for 10 seconds at least
Nothing happened. So i didnt get the flashing menu or mode on screen
Then i put unplugged the phone, put the battery back in, and tried again, suprisingly the LG Logo came up, but now it hung there.
Removing the battery...
EDIT: I removed the battery, now working good. Hopefully this dumb sH*t wont happen again. Beautiful phone. Hope this solved everything
If not, try doing a hardreset maybe? Hold power + Volume Down Key BUT ONLY IF YOUVE TRIED THE ABOVE METHOD A FEW TIMES. cause all your data will be gone POOF

Mi Mix almost totally dead - is there life?

Ok, it's been a couple days since I posted on the Q&A about my Mi Mix suddenly not turning on after powering it down with close to a 100% battery. Now, for the first time since this happened I plugged it into my computer (Mac) and although the computer didn't recognize it as being attached the led light above the charging port is flashing red every half second. Any thoughts or ideas?

Looks like your device switched to QCOM 9008 Download mode.
It should be detectable via MiFlash; you will probably need to flash a fastboot rom with full factory reset.
But try the following first:
- disconnect from charging for 1 day
- charge it for a few hours
- hold on the power button for 2 minutes
I'm happy to report that my phone is now working again! I have no idea what happened but after charging it in the official charger and cable for a while it took a charge and changed green then powered up. Really hope it doesn't happen again though

Cool, probably battery percent froze so looking full when actually it was flat.
my own xiaomi wont start too
My Xiaomi Mi Mix showed low battery sign so I plugged it in to charge. The phone immediately went off. I pressed the power button to restart it, it showed the Xiaomi logo then immediately went off and since then (this was 2 days ago) it has not powered on.
Kindly note the following:
1. It didnt have water spilled on it
2. It didnt fall or have any mechanical damage
The only thing was, the battery was low, I plugged it in to charge and it went off and never came on again. I have used the same charger to charge other phones so I doubt if the charger is the source of the problem.
Kindly help, what is wrong with the phone?
thanks

Try maybe flashing a custom rom, or even flash a custom recovery and check if the phone charges while in recovery mode so you know if the problem is with hardware or software.
Just unplug battery overnight, usually sorts this sort of thing out, while the back is off disconnect the port cable from motherboard insure it's clean and reconnect
I replaced my battery and it really was not that hard at all. Mom had a
i have the same problem. I believe it is a software problem. hope for a update to fix it.

Naa, just leave the battery unplugged overnight, will take awhile to start charging again but should be fine
Yes, same here. The phone just stops charging and as well starts discharging rapidly with the charger connected.
I am on the PIXEL rom currently.
As I had tried the RR ROM and the look and feel for the phone wasn't quite to my liking.
The phone charges fine when it shut down. But refuses to charge with any PC/brick/cable.
Also, the phone heats up hard at the general fingerprint scanner & Camera area. When this happens.
I have no other choice to shut down the phone and charge it and then use it. Whats can i provide for any DEV to check the problem?
Is it a kernel fault? Software? Hardware?
Any help would be appreciated.
TIA

Hi, I get it back to charging after doing a hard reset by plugging the charger to the phone and at the same time press and remain power button, the phone shut down and when i re-start again it keep charging. Try that
I have Xiaomi Redmi Note 8 and my phone was shut down when i completely discharged the battery. I tried the charging with original cable and adaptor but didn't charged, only seen battery icon. For just trying, I charged with a powerbank and ITS WORK. Firstly the powerbank light is going off within 5-10 second, I tried a few times reconnect the charge cable and booting my phone then the powerbank light wasn't off and my phone started normally charging.

Yup.. I hv tried all the above...and also tried connecting to laptop thru USB cable.. but absolutely nothing happening.. it's dead as a Brick
What did you do before
Nothing actually.. went to bed in the night and kept the phone aside.. morning it was off thought battery empty and kept for charging. But even after an hour I noticed it wasnt charging and I cudnt turn it on either..
maybe open back cover and see What happened?
replace battery or What?
or replace Screen?
have you done any system updates or opened auto update?
There was an ott update that day which got auto updated..
Mostly is that OTA hard bricked your device. Your device ran out of battery while installing it.
The mobile had enough battery and the update got fully installed over wifi. After that I hv used the phone too. In the night I went to sleep keeping the phone aside and morning this happened.
Maybe Another OTA came and bricked your device.
My Y9 Prime had recieved 2 updates in a row so I can confirm it is possible.
if that is the case I cannot help you but if it is battery bug(like Note 8 battery drained overnight and battery failed)you can try reconnect the battery or replace it but I am a noob of doing that
Do you have spare phones?
What happens when plugged to computer?
Ohh. 2 OTA updates....
No sound or anything Wen plugged to comp. It's still dead.. tried all combination.
then mostly 2ota bug or battery bug
if screen bug you will hear vibration
Ohh ok.. any solution for this...???

Question Redmi Note 11 4G (Global) won't charge and turn on after a update try

Hello,
My costumer tried to update his Redmi Note 11 from 13.0.9 to 13.0.12 rom via Update App, I don't know if he made something wrong, but now the phone won't charge and not turning on.
When I put the charging cable, the battery symbol blink some times but nothing happens. I'm sending a video that shows it.
I can't get into fastboot mode and when I plug it on PC nothing happens, only the battery symbol blinks and Windows not recognize the phone
Can this phone be saved?
Thank for all help in advance.

My guess is that they tried to update when the battery was so discharged, then the update didn't finish correctly, still seems no battery.
When you charge the battery again, try to enter to recovery mode and do a factory reset, try to boot.
To enter to fastboot mode you can, either press volume down + PWR button, or pressing volume down and at same time, connect to your PC, but not much you can do through it, if the bootloader is locked, and plus, the user didn´t start the process to unlock it.

Thanks for your answer.
I charged the phone for 24 hours and it is the same as it appears in the video. It didn't charge and it won't turn on. Only the battery symbol appears.
I can't get into recovery mode or fastboot mode.
I tried to connect it to the PC holding Volume- but nothing happens, the same battery symbol appears
Bootloader is locked.

Well, you don't need to charge for 24 hours, it seems to me that something in the hardware is damaged or was disconnected, like the charging flex connector, it could be an internal error, you should check it with the help of a technician, the symbol shows no charge at all. After you solve it, at hardware level, then you should try some tips at software level.

Hello brother. Im facing the same exact issue. did you fix the phone. Any way to fix it?
Today my phone has fully discharged and I have the exact same issue.
Impossible to boot and I cannot charge it, as it results as the blinking of the battery icon...
On my side, if I plug the USB-C, it does not even says it charges / but it vibrates each ~5sec with the same (empty) battery icon...

hi..i have already posted this on a thread in the morning. i have same exact issue.
I dropped the email to xiaomi and they after lot of back and forth emails, and trying everything out, they asked me to visit a service center. apparently after doing some research the only way to fix it is by opening the phone and disconnecting the battery and connecting it again.
My phone was less than a month old and ordered from amazon. they are going to accept the return request luckily.
I know guys, no one likes to disassemble a device or take it to a repair service center, but the issue is clearly related to a hardware fault, i.e. battery, charge flex connector or whatever they are called.

I had the same issue, wouldn't boot or display anything, so I took the phone (spesn) to a service center.
The technician told me all he did to repair the phone was a software upgrade... No problems since then, it probably can be done at home somehow...

It seems a hardware issue, but...
Some bad flashing cycle can cause the display not "turning on" at all, but really, it's just not showing a thing, to cover and check this possibility, you should flash a different firmware, just check out, the state your device gets connected, and try flashing a firmware.
For everyone who has this problem, remember that with locked bootloader it is impossible to flash the official rom by miflash.
The only alternative you have at the moment is to try to start the phone in EDL mode and that means opening the phone and seeing how to do the test point.
IF the pc recognizes it, they are in luck and it can be recovered, but due to xiaomi policies, only some people have accounts authorized to flash by EDL and charge for the service, many do it remotely and are found on telegram.
All the lot of issues, users are reporting on this device, they are realizing that Xiaomi is forcing them all to unlock the bootloader.
Unlocking the bootloader may be the fastest and cheapest way to escape from an eventual disastrous scenario.
I have the same issue with my Redmi Note 11, I successfully update it, I have 3 other chargers and cables I try all possible methods to eliminate possibilities even check type-c port but phone not charging after mini 13.0.12 update. How we gonna have fix this or is the are a plan from xiaomi to have solution?
