my battery was running low, (and coz poor battery issues with JPY), i didnt notice when it switched of. normally i use the power button to turn the screen on to unlock, but instead i realised the phone had been off as it was now booting up...it booted up fine went into the homescreen and then vibrated once and powered down.......now it was powering down for a long time and occasionally there were vibrations and the lights on the home keys were constantly on. the screen was black. i got home and tried to charge it but the progress bar showed no progress on charging, i tried to switch it on but it would go to startup screen vibrate cupla times and power down. so eventually had to do a hard reset in recovery mode. tried every option but in the end had todo it by wiping data.
now the thing is, is this supposed to happen? if ur battery suddenly losses power ur whole fone will screw up?
for future ref if ur battery dies dont try to switch ur fone on until u got some charge in it and use the home key to put screen on..
Sounds like it could have been faulty firmware .
JPY does not have a significant battery drain problem per se .

Black screen, vibrations and no boot after restart
Hello! I had almost the same experience (Black screen after reboot and occasional vibrations) only mine refused to boot even after memory wipe and after flashing new roms.
Was your phone rooted? Because I think rooting a 2.2.1 rom (XWJS3) was the beginning of my nightmare. keep in mind that the phone was working like charm for two months. This was the second time I had a problem. The first time the phone started after performing a factory reset by itself!
In case this happens to you next time and for every non experienced galaxy player (like me) reading this:
Don't panic! Blank screen, vibrations and no boot doesn't necessarily mean a hardware problem. Finally I managed to fix it flashing eclair and repartitioning with pit512. Now I'm a happy XWJS8 user
And a question for the experts: Any clue why this happened? Is it really a rooting issue? Can a cheap Chinese battery from ebay cause this?
everything was stock on mine, no root.......maybe thats why i could recover it??!!
Maybe! and I hope the reason is faulty firmware as JJEgan says. If this is true, your phone will be fixed by the next update.
I was very urge... the same happened again. It's been a month of smooth functioning and now after a simple restart, the device doesn't boot for absolutely no reason (Stuck on black screen constantly vibrating). Since my phone wasn't rooted, and I haven't seen many people talking about a problem like this I suspect:
1. Faulty hardware (for a few devices including yours and mine)
2. A Bad app.
Contacts Vanished
Hey Everyone
Im having similar problems, i updated my sgs to the js7 version of froyo, then rooted it with oneclick method. this was as i got the phone a month ago. Its been smooth sailing since then. But last night the phone powered down and wen it loaded up it had no contacts, my sms where still there but all the apps had a force close issue none worked. so cleared the cache in recovery. Still nothing so i did a factory reset and once loaded up. i formatted the sd and internal within the settings option. So the phone was now clean. I then connected to pc luckily had backups so installed titanium restored all my apps n settings. Using kies restored my contacts n thanks to an app called sms backup i restored those.
So all was well and worked again. I didnt restore the apps i had installed within the last week to make sure it was not a faulty app. I was happy, but now tonight it did it again. No contacts again.
Pls help
Any suggestions
That's exactly how it started for me. One month after rooting froyo 2.2.1 Suddenly everything force closes and the device hard resets by itself. I reinstall all the apps and then after one month and performing a simple restart, it refuses to boot. Stays in a black screen and vibrates every some seconds. I flash a new rom but does the same. Problem solved after repartitiong and flashing original eclair with pit 512. Reflashed a 2.2.1 rom and everything works perfect (the phone now is unrooted and with a nice clear stock rom). But then after one month again (!) I realise that some videos refuse to play. Trying to restart and craaash. black screen, vibrations and no boot. Did the same again (repartitioning and flashing) and now I wait for another month to pass and lose an hour of my life to do the same again. No idea why this is happening. Is it possible that rooting messes with something that stays faulty after restoring the file system? is there an app that we all installed and caused this mess? please this is the most serious problem I've red in this forum and still a mystery. I believe this thread should be sticky and we all share similar experiences because this looks completely random!

Hi everyone, after trying everything I could to fix this phone I don't know what to do anymore so I'm here asking for other options.
So the story is, I was just using my phone as I usually would that day and it just randomly turned off and won't turn back on anymore.
(it randomly turned off before a couple of times but it would always turn back on)
- It won't go into recovery mode or any other of the 'modes' (I tried all the different combinations of pressing the keys).
- It's not a battery issue as I've tried my battery on my brother's phone (he has a Note 4 too) and it worked fine and I tried his battery on mine and it wouldn't work.
- I tried the 'drain' method (removing the battery and holding the power button for a minute or more).
- I tried using multiple cables to charge my phone nothing worked.
I didn't drop my phone, wet it, root it or anything and it was working fine the day it happened until it just powered off by itself. When I plug it in my laptop it would make
a sound indicating I've plugged something in but nothing happens. It was version 5.1.1 model SM-N910F.
TLDR; Is there a way to somehow recover the files in the internal phone memory?
This is happening to me as well, also started in February. I'm suspecting a hardware issue. Tried it ALL but rooting. In the past 30 minutes my phone has booted and rebooted itself till it died. If someone can confirm it is a hardware issue. Maybe it's time to unite and get it fixed for free. ~Tamarnouche
Recovering data from a brain dead phone may not be possible, as it probably need some internal component replacement which may erase the data(Mostly). Have u tried connecting it to pc? Better give it to service immediately. Good Luck.
My phone has done exactly the same thing, happened in February too, initially it did the random freeze then started to reboot itself, went back to stock software and full wipe but no improvement; now it will only boot if I leave the battery out for a prolonged period, otherwise it doesn't respond to the power button at all.
I occasionally see MMC Read Fail on boot but not all the time so presumably the internal memory has a bad contact or is failing.
Can it be replaced?

I have the same problem with my Note 3. Only if I keep the battery out for a long (over 24 hours) time I can see the boot logo. So if you find a solution to this kindly don't forget to tag me, will really appreciate it.
I was wondering..
I came across this Forum group since I was looking for boot problems with my SM-N910T3
I hope flashing pit will resolve this..
I recently started to have some low level issue and was hoping it was partition/boot related and not hardware.
Randomly phone boot directly into Download mode with error;
ddi: mmc_read failed
Often I have to pull battery and hold down /power / home for 10 sec to boot up again.
Thanks
Saturday night, I plug my 1 week old phone on the charger at 9%. I power off the phone and see the battery charging animation. I turned it back on as usual but this time my phone did something I've never seen before.
It started bootlooping!
I was like what the hell.
It loaded up to the lock screen and then rebooted. This happened over and over again for about an hour.
After googling, I found a thread about a Redni Note 5 pro having the same issue.
The solution was to hold power and Volume down until the phone rebooted to recovery.
After doing that, I was presented with the option to reboot to system, wipe phone (which I definitely didn't want) and connect to My Assistant.
I chose the first option and sure enough....my phone was stuck in a boot loop once again.
This is my first Xiaomi phone. It's not rooted at all and has locked bootloader on the stock 10.3.5 ROM. Fresh out the box...just a few apps, some photos and texts.
I've seen stuff like this before happen with rooted phones but never on a brand new non rooted phone.
Fortunately (and with lots of prayer), I was able to let the phone battery drain out completely since it wouldn't power off.
Sunday morning, I plugged it back on the charger and to my surprise, I saw the battery animation only this time!
After charging fully, I turned it on and saw it bootlooping again. After 5 mins, I decided to remove both my SIM tray with both SIM and micro SD.
THIS time, the phone stopped bootlooping entirely! Again....what the hell was my question ?.
Normally, my nerves are steel but yesterday, they were more like spaghetti lol
Against my own judgement, I wanted to test if it was my own SIM card causing the issue or if my micro SD card caused the issue.
I placed the SIM try back in with each card 1 by 1 however, the phone immediately started bootlooping on it's own right from system!
I've never seen this before with any other phone or brand I've used in the past.
This activity occurred again and again regardless which card was inserted. With no cards, the phone worked normally.
I decided, you know what, at this point, I'm going to back up my data during and factory reset since now I have access.
Thank God that worked!
After many hours of backing up data, factory resetting my phone and then restoring everything on Mother's Day ( which meant working around free time and planned activities with my Wife), I am happy to say my phone is back working normally with the same SIM card and Micro SD as if nothing happened.
Fluke or not, definitely going to be watching this phone carefully to see if the problem is gone for good.
I will say this, when I first took the phone out the box last week, I turned it on and watched it update to MiUI 10.3.5. Normally I factory reset my phones after updates to be safe but since the phone was still new, I did not factory reset this time. That could be the reason it did this...I'm still not sure.
Sometimes I power my phones off, connect the charger and turn them on. For years I've never had an issue or doing it this way. For a few days I didn't have an issue with my Redmi Note 7 either. After this experience, I will stop doing that entirely.
My question is, have any of you encountered random random boot loops with any of your Xiaomi products? How did it occur and how did you fix it?
Got the same problem, fixed it the same way

Hello,
today I got the same issue as you stated above.
I tried to remove the SIM card (while the phone is on) and the phone brought me to the startscreen instantly. Inserting the SIM card caused the bootloop again ..
I googled this issue and found this thread,
went into the Recovery mode (Power + Volume Up) and did the Data Wipe.
Consequently, I could start the phone with my SIM card without problems ..
Later I found out, that removing the "Telephone"-permission from the "Contacts and dialer" app caused the bootloop.
(On my Stock 10.3.4 MiUI non root)
Greeting,
Dorian Rec

most probably removing the "Telephone"-permission from the "Contacts and dialer" app is causing the bootloop - remove SIM and data card, start phone, fix the settings issue the get back the SIM

It's MIUI 11.0.1 still the same problem
Ok I updated my phone to MIUI 11.0.1 it still has the same problem but thanks to everyone in this thread I
finally fixed this problem that kinda scared the crap out of me.
Thanks Everyone
I did not know this was a thing until last night. I'm on MIUI 11.0.9
My phone restarted out of nowhere and then my flash light came on by itself, gps was turning on by itself and the reboot/switch off screen kept coming and going, little while later it went into the loop. wouldn't even get to the android screen, i couldn't go into recovery mode either it was so bad. I let it die last night and after seeing this thread i plugged it in, and took out the sim (no memory card). So it seemed to work, though the torch and reboot/switch off screen did show up but nothing like yesterday where it kept interrupting me while i was trying to backup my data. Luckily i do a manual back up regularly.
I changed the "Telephone" permission and it went into the bootloop immediately. It turned on, and i started to backup the last of my data and it went into bootloop again. It's been 10 minutes now.
I noticed it seemed to go into bootloop every time i turned off gps,cell data, or was clearing files from my phone. Honestly i thought i was being hacked. Any suggestions on what I can do?

It looks like a hardware problem, if your phone gets into bootloop even there is no sim card - try to change to the other position for the sim card
same issue
gosh scared the xxxx out of me too! I was uninstalling updates uninstall to my redmi note 7 cause too little space and it went into reboot loop. removed sim and giving permission works. I wonder how to do it if removing sim didn't help me boot! how would j have been able to add back permission. what's worrying was I didn't remove any permissions , I only did uninstall updates to all xiaomi apps

Seems like this problem exists on MIUI 12.5 too. I haven't tested the fix yet.
