[Q] Xperia X10i Bricked ! - XPERIA X10 Q&A, Help & Troubleshooting

Device Xperia X10i, Unlocked Boot Loader, Rooted, Installed Jelly bean Rom of Feralab. Device worked perfectly on it. Since yesterday, after waking up, found my device bricked. Symptoms displayed after device got bricked :
a) If connected to wall charger with battery present, device only displays green light for 15 to 20 seconds max and then green light goes off. Then no activity in the whole device.
b) If connected to wall charger with battery absent, device again shows green light (with battery absent that is).
c) Tried SEUS, Answer : After the complete successful operation : Nada Nothing !
d) Tried Flash Tool, Still Nada. Tried flashing Xperia Stock Rom : Replaced System.sin , Header.sin and what not etc. "Even checked No Final Matchup" while flashing. Answer : Nada. !
e) Stock Used is "X10i_3.0.1.G.0.75_CUST-IN_GENERIC_1237-0692.ftf" flashed it. Still Nada ! However, no errors occurred while flashing.
f) Device when trying to switch on, displays green light blinked once, then vibrates and then just goes simply Naaadaa !!!
Nothing at all. Please help. If this helps, I am attaching log file of flashing device via flash tool. Man, device is just bricked. Answer and help appreciated . Thanks in advance.
Since I can't attach link to external log file on paste bin : here's I have uploaded the log file.
Update : Since I was on Fera Lab's Jb earlier, I want to notify that my "Unknown Sources and Debugging" was not checked in phone settings. It wasn't on and now that its bricked, I dunno whether it will make any difference or not ? In bricked state, with "Unknown Sources and Debugging" not checked. Can't get device to on, blinks one time green signal and then vibrates and nothing afterwards !
Update Number 2 : Hey, after completely keeping aside the battery for more than 24 hours, I connected the device to external wall DC supply (while battery was removed and never inserted after the 24 hours interval that is). After connecting the device to DC wall supply, it gave me the same response, flicked and showed green light and then vibrated and then nothing ! F1 anyone. !!!
Update Number 3 : http://talk.sonymobile.com/t5/Xperi...on-Flash-mode-even-when-plugin-to/td-p/273134
Just Googled my problem and came to this link. I can very much relate to the link although, His device was water locked, (there was this small white rectangle, if it is water damaged then it will be red) Surprisingly, his device which was water damaged shows the same symptom as mine. So, i checked mine, but the sticker or white rectangle for moist / humidity checker is white totally. So I guess it can't be water damaged, although, it showed the same symptoms !
Update Number 4: Since green Light was always On, I thought what if its in flash mode and much to my surprise, the device is in Flash Mode when I switch it on, how I found out : While flashing via SEUS, I didnt press the back key and the device got connected in flash mode by default, So i narrowed down the problem to something that : My device boots to Flash mode and not as it normally should ? Is it a mother board problem ? Can it be cured ? (god no please not mother board problem) So ? Any thoughts anyone to make it come out f the flash mode. ?

C] Tried SEUS, Answer : After the complete successful operation : Nada Nothing !
after the Successful Operation did you unplug the phone and tried to turn it on?
After the Successful SE Update Services was successful my phone didn't start, then i removed battery and reconnected, power on and works fine.
search in forums for Dr Goodvibes his suggestions did help me.

Your phone indicates an unlocked bootloader, just for your information.
What's the thoughts on the battery? Was it in a good service state?
Take the battery out of the phone for 48 hours and then put it back in the phone and power the phone on.
The green light for a few seconds indicates the phone is attempting, or in a recovery state.
Your phone may have just had a 'moment' and has a "locked instruction", that just needs to be cleared with no power applied to the chipset.
This has worked for others and is more voodoo than science, but worth a try.

Oh thanks for the update about the boot loader state. i definitely be keeping it apart for 48 hours and will update you regarding the same. thanks for the reply, you know i love this set of mine and your precious replies gives me hope.
Regarding the battery state, i guess it was okay, gave me a 1 day backup on the phone. So i guess it was in a kinda okay service state. though am not sure whether its fully charged or not. i don't actually know the power state / current charge level of the battery though coz i found the device bricked. if there's anything you can suggest, will be really helpful. though thanks for the information.

So I waited and waited for some more time, couldn't wait any longer for the 48 hours duration. Does t has to be 2 days ? I just wanted to bring my device back to life. Though, after giving up shortly after 12 + hours, I flashed it again, it did successfully, although, nothing even now, green light followed by a vibration and then boom. nothing ! f1 help needed ? btw, does it has to be 2 days?

I would have placed the battery back in the phone and pressed the power button and see if it booted, or allowed you to get to CWM Recovery with blue light or xRecovery(if installed).
One day, one week. How long does residual power remain in a circuit board to hold the current date/time before resetting?
Maybe buy a cheap BST-41 1500mAh battery for the XPERIA X10 and try that. Could be just a bad battery.
You could check the battery with a multimeter and see if it still has a charge.
My knowledge base stops at this point as I have no experience beyond this.
Good luck.

Thanks Dr. Goodvibes, I definitely will keep you posted. Though, when I plugged the battery in, first I did check, nuthing ! green light + vibration. and then it goes blank. I installed my feralab jb rom via xRecovery so, yes it is there (installed) but afterwards I have flashed the stock via SEUS so i guess even xRecovery is gone now. I am not for sure. Though it was installed earlier. Right now I am thinking of keeping it apart till the time i found a new battery, it can be even 2 + days. Even 1 week. I will wait for a week now. Thanks for letting me know all about this. Keep me posted.

[Q] Xperia X10 won't turn on.

Hi. The phone application was not functioning well and the F/C dialog showed up. I powered off the phone and from that point, the phone won't turn on.
The battery was fully charged before this happened.
When I press the power button, the phone vibrates for half a second, the screen brightens up but does not show anything but a black screen.
I removed SIM and SD cards, removed the battery and performed the above steps but nothing happened.
I also tried to put on the charger to see what's going on. Once I plug the charger, the phone's screen brightens but shows only blank (even without pressing the power button)
When connected to the charger, the green light for charging is on for some minutes, then goes off automatically.
I tried to connect it to the PC, and PC Companion finds the device as usually. It even shows the dialog on the pc screen to mount the device.
I tried a hard reset, but does not work
On some point, the sony logo appeared and then a dialog saying: "sorry process system is not responding". The first time I pressed Force Close and the phone turned off. Immediately after that, the phone turned on and showed the exact message. I pressed "Wait" but nothing happened in the next 15 minutes.
I called Sony's support center and they suggested a software update. Did the process exactly as it should, but again, even after the software update the screen shows nothing but black. It is all the time brightened for some reason.
I tried to turn off the phone for some time by removing the battery, but as soon as I put the battery back on, the phone's screen brightens and stays that way forever.
The phone was functioning perfectly up until this issue. The only application I had installed apart from some games, was AWDLauncher. On the screen I had only a TASK widget and a battery status widget.
The phone is 3 months old and has been always in perfect condition.
ANY help would be appreciated!!!!
Many Thanks
Try to format phone with this method hope it should work as it seems the issue is with OS only ..

I tried the steps found in the link you gave me, but I couldn't go any further after step no (5) from the tutorial, as it would require to enable Debugging mode and I cannot access the OS (since the device won't turn on).
Is there a way to format all the contents of the device and have them replaced by running SEUS (as it always says that my device is up to date now)?
Was it this:
http://www.sonyericsson.com/cws/sup.../detailed/updateservice/xperiax10?cc=gb&lc=en
That Sony Ericsson told you to do?
If not, use that.
Download it, follow the steps when it says you have the latest version, press "Install Anyway".
Hope this works.
Hi itTim. thanks for the response
this is what i did but no improvement at all ((
Sounds like you broke your LCD screen somehow.
That would suck because I broke mine and it cost me $200 to fix.
Hi Hypercore.
Yes that could be the problem. The thing is that I always took rally good care of the phone, always carried in a leather pouch and never droped it. How sensitive is this lcd anyway?? Did you notice any cracks on your lcd or was the problem simillar to mine?
Thanks
When you turn on the phone does the lcd backlight turn on?
If so, look for any faint lines of color (usually a hairline size). If you see any of those then your screen is cracked.
the backlight is on, but there are no lines of colour on the lcd screen.
another weird thing is that the green light on the top blinks one or two times every time i put on the battery. even if the phone is off, once I insert the battery turns on automatically after a couple of seconds.
If all else fails you could try to flash back to your original fw with the tools here:

That won't do anything.
I had almost the same issue. Nothing worked. But, when I removed the battery and left it for a day (24h) without it, it just started working again. Still working without issues..
Good luck!

Phones are very wierd pieces of technology. I once bricked my k610i and that's a phone that's supposed to be impossible to un-brick, but out of nowhere a month or so later i picked it up, hit power and it turned on perfectly. Made no sense at all, but it worked.
Taking the battery out for a long time probably took all the electrical charges from it (kind of like how a computer power supply / monitor can hold power charges) and reset your handset.

Indeed. It could be a frozen chip, memory fault, power-regulator and so on.

if you have done this and did not worked , then it is the LCD.
send it to workshop and check it there.
Guys i Really need the solve of this problem , my xperia has blank screen now without backlight and the phone completely doesn't work . when i put the battery and prees the switch botton it gives me 3 red signals , i've updated and hard reset but it didn't work , and btw the LCD is fine , any idea. did removing the battery worked???? . please answer
After a looooot of time since my latest post, finally my Xperia came back to life. There was a battery failure which means the phone was ok all the time. Weird thing is that the led light showed that the battery was charging ok. I removed the battery and after a lot of time it is working ok again. This was really really odd.
FYI for anyone else that gets this issue.
I just had this for the past hour after trying to change my baseband....could not get it back for anything.
What I did finally try was run another baseband via flash tool, connected to usb and it started flashing....after flash phone powered on again...yeah I agree with everyone, that is freaking scary when it happens.

[Q] Semi-dead X10

Greetings!
This isn't the first time my X10 stops working, but most of the times simple SEUS or flashtool flash fixed everything. But this time it's diferent, that's why I'm asking for help.
For the whole previous week my phone was playing with me. Random reboots, power button stopping to work, taking the phone out of the pocket just to see it turned off and such. This is how it reacts now:
1. Trying to turn it on: Green LED flashes for a split second and then the phone vibrates and that's it. No reaction. If I leave it then, green LED flashes for a split second from time to time. Have to reinsert the battery to make it 'react' again.
2. Trying to use SEUS: It detects the phone alright, the phone seems to enter flash mode, but the status bar doesn't even start filling. After some time I just get the message that the flashing failed.
3. Trying to use flashtool: Pretty much the same: status bar doesn't move, and after some time 'Flashing failed'.
4. Plugging it into wall charger or usb: Green LED lights up like in flash mode for 5 secs, then turns off, then lights up again and alternates like that every 5 seconds or so.
Any suggestions? I was on Wolf's V6 rom, locked bootloader, and my warranty ended like 5 months ago. Pretty sticky situtation. I'd really like to revive it without the need to bring it to repair or something. Eagerly waiting for every reply.
Thanks in advance!
Bump!
Please anybody!
probly cos of dead battery
I would say it was most probably because of your battery is ****ed, your battery connecting pins are screwed, or something gotta do with hardware.
Try leaving the phone on charge for at least 2 hours to see if that fixes it.
Or try to "Jump" start your battery.
I have read how to do this in a thread somewhere...i think by omegared...try and search for it
U can use external battery chargers to charge your battery. Or you can borrow it from someone for few hours
CheersS!

Thanks for all the replies, I really appreciate that!
>pheel
I kinda suspected my battery would be faulty. I remember I dropped it accidentaly around the time it stopped working. The fall won't be over 50cm, but I guess it was still fatal...
>gregbradley
After it stopped working, I left it plugged into wall charger overnight. Had just green led flashing and still no boot. Jump starting seems to be something I don't wanna mess with
>milton.bain
Don't really have access to any of these items, but I guess I'll try to get it from somewhere.
Ok then..
just buy a new battery then
if you want to check before you pay, find a friend with a working x10 and borrow theirs...
Noone I know owns a X10, but someone I know works at the place I bought my phone, so I'll try to borrow a battery from there for a few moments.
some of the symptoms of your phone indicates that it might be a motherboard problem.
the best suggestion is that you try out another battery in your phone, and see if it will act the same. if it is, have it checked, it might be hardware.

[Q] Xperia Ray not charging/ need to unroot to send for repair

Hi guys, i consider myself an intermediate around the android OS and i have tried most solutions that came to my head with no results.
My problem is the following:
My xperia ray is running stock rom ICS and is rooted. That's it
One day my battery suddenly drained to 0% and phone shut off.
Since then, i cannot charge it. Whenever i plugged it, the led blinks red /sometimes keep blinking/something always red/sometimes the phone boots after 10 seconds from entering the main page it will reboot.
I tried a different battery, the phone worked, so i bought another battery but the same happened, it suddenly went to 0% and not charging anymore.
Now I cannot access the phone via USB since it is not recognized and i can't work on it since there is no power,
What can i do to at least unroot it before sending it to warranty?
Try reflashing..

Heard of universal charger??Charge your battery to 100% using a universal charger..get a stock ftf file from here
http://talk.sonymobile.com/thread/35239
use flash tool and flash your phone with this stock ftf file..
then your phone should work..
hope i helped you..btw have you unlocked your phone's bootloader ?

unlocked bootloader and rooted, or can you root without unlocking it? I actually forgot since the ray was always my secondary device.
Do you mean i rule out any hardware problem, this is related to software only ? Since my Pc cannot recognize the phone, it gives me usb device not recognized..
Might be a hardware problem..cant say for sure..

We cannot rule out any hardware problem as of now..,yes you can root without unlocking the bootloader.
This might be a software issue..are you running on stock kernel ?
Can you enter into fastboot or flash mode ?
Have u installed the adb drivers? does your pc recognise any other xperia 2011 phone ?

My phone isn't holding any charge, the battery is always 0, when charging it only gives red lights. Sometimes the phone will boot, it will show the xperia logo, go into the main lockscreen for 5 seconds then shuts off.
Buying a universal charger would mean waiting for 1 month for it to be delivered since i only found it on ebay

Was it damaged by water?
it's really easy to check if it was water damaged, open the back cover and look for a small WHITE rectangle, if you see a red rectangle it was water damaged, same with the battery it has a small white rectangle
IF NOT..see if SUS or PC companion recognises the phone..Repair your phone if it recognises.
IF NOT take out your phone battery for 15 seconds..put it back turn on the phone..and connect the charger but DO NOT SWITCH ON YOUR PHONE..let it charge for 5 HRS continuously..
IF NOT Try using another battery to turn your phone on...and see if it charges up..
Still NOT working?,Have you unlocked your boot loader ?

Thank you for your suggestions, i did something in the meanwhile.
I have a co-worker who has the exact phone, so i put my battery in her phone and charged it. In the meantime, i used her battery inside my device and used flashtool to flash stock ICS.
My device had bootloader unlocked, i managed to lock it back.
Now after i have a clean ICS copy unrooted. I return my friends phone, put in my battery and put it on the charger, the phone recognizes the charger, it gives me the small flash logo on the battery icon but the battery meter is not charging.
I'm afraid it's going to stay on until the battery drains to 0 and then i'm back to square one.
At least now i'm unrooted and can check the sony service center if they could do anything.

The battery voltage is increasing or not ?
Do not trust the battery meter...The voltage reading will tell whether its working fine or not..
Close to 4200 mV is 100%
While 3400 mV is low battery less than 10% typically..
Hope i helped you..Just hit thanks instead of sayin..U know there is a button..

Well when it's plugged in, the lockscreen says charging. The battery icon has the flash sign on it. It is recognized by my Laptop. But the battery status is discharging and i monitored the voltage, it was decreasing.

Check if the port is clean and check the battery pins and pins on your phone.
Do you have the possibility to test another battery? So you can be sure it's not just your battery...
did you have try to let the smartphone shutdown by itselft? and charging the battery after that...
Sounding more and more like a hardware problem. If you have access to a voltmeter, turn your phone off, remove the battery and plug your phone in, check the voltage coming out of the battery terminals in the back. It should be ramping from 1 V to around 3.6 V (at least from the USB port, it might be higher from the wall charger).

thanks for the reply guys, I'm updating the thread so other people might benefit from reading it. I went to Sony service center. The technician first told me there was water damage, although i'm confident that the phone was never dropped in water. Also he showed me that the pins for the battery were bent.
He said he will inspect the motherboard, if it's not corroded (from water) he will replace the motherboard since it's still on warranty.
If it is corroded, he can't do anything.
The strange thing is that the phone is working 100% except i cannot charge it. USB function is working correctly.
PS: Always Unroot and re-lock your bootloader before sending to service, they will check for these and can refuse to serve you by the warranty.

Changed LCD, dead battery? - Troubleshooting help.

Hello XDA.
Update.
Changed battery. Nothing changed.
Tried the suggestions posted Here no change.
Before I started this process, I was able to turn the phone on, hear the startup sounds, and charge it, no problem.
Yesterday I changed my cracked LCD (and digitizer) with one of these witrigs .com/oem-lcd-with-digitizer-for-sony-xperia-z2 (I'm not allowed to post links)
Followed the instructions provided by witrigs.
However, after having put it together again, when I try to turn it on all I get is 3 red blinks. (This would indicate low / empty battery, right?)
So I connected it to the charger (tried both wallsocket, and USB from two different computer, and different cables.) and all it gives me is a red light.
Normally, this would mean that it's charging, as far as I know, but it stays like that for hours, without any changes. So I was puzzled by this, googled to no avail.
I can not get it in flashmode, nor fastboot mode. However, here is the interesting part. When I disconnect the battery from the back and connect the phone to a charger (or USB from PC) the screen lights up, and shows me the charging animation.
In addition to this, when the battery is disconnected, I can get it into fastboot (Blue led, if I've read correct, I can not get into this with the battery connected.)
With this information, and my lack of real knowledge about how this technology works, I assumed the battery was broken, so to test that a bit further, I checked it with a multimeter.
It's currently showing 4.2v. I don't have another battery I can try with as of now, nor do I have other readings from other batteries. Maybe some of you do.
Anyway, have any of you encountered anything like this before? and or have any suggestions as to what I can / should test or try next? - I'm running out of ideas. (I will buy a new battery when I have money, but it probably will not be here in 5-8 weeks, due to when I get money and shippingtime.)
Thanks in advance for your time, and I'm terribly sorry if this has been talked about before. I searched, but maybe my searching skills are bad, as I could not find anything like this.
Edit: For the sake of trying wild things, I tried to un-brick it using flashtool and a custom FTF. Exact same condition.

Same problem help us guys
What THE?
Your situation is exactly mine :crying:.
Always dreamed of this phone model, bought a cheap one with broken glass, it was working fine, I tried with a controller and was working.
Bought a high quality screen replacement that wasn't so cheap (quality seems pretty good actually).
Opened the phone using a hair dryer, it was easier than I thought and actually easier than any phone I ever opened.
Changed screen, and SAME PROBLEM AS YOU, 3 red lights, no boot. I also tried everything you tried, it shows up the battery charging icon without the battery.
ps: There got to be something pretty wrong with this, PLEASE SOMEONE HELP.
Keep Cool

I also am in the exact same situation. I was very carefull when I changed the display and I took my time for it (two hours!)
I used a hairdryer to make the glue soft. Maybe this overheated the battery? That is the only thing I can Think of.
Anyone else with the same problem?
Anyone else with some tips?
update: ordered a new battery. If I overheated it, it will probably work again.
Does any one now if there is some intelligence that checks if the battery has problems / damage / too high of a temperature?
Try flashing kitkat ftf without the battery. I think this is a firmware failsafe thing due to difference between display panel and display firmware on the device. Battery even when damaged should not prevent boot if the device is connected to a power source.
This is just a wild guess, too. Try flashing older ftfs that may be free of these failsafes.

Thanks for the good tip! Sounds like that could be something too.
I tried/will try it in this order :
1) original loader, load the phone for 2 days (no success)
2) wait three days without loader ( I read about others that were about to send their phones away and then they started working again)
3) change the battery with a new one (its on its way)
4) your idea, flash the phone
I was thinking about overheating sensors in the battery. Maybe it "says" to the phone "I will not charge myself. I am damaged" (because of the high temperature when using the hair dryer).
Maybe the battery has to forget that it once was too hot?
I also thought about that the phone does not want the battery because the battery reported the high temperature to the phone (and probably an unique ID).
Maybe the phone stores somewhere that that battery is a battery with problems and thus has a "ban list" somewhere?
Any way, thank you for the tip! As a final solution, I will do that.
If that does not work, I will probably look for another phone

I was thinking more about the things you wrote....
What about if it is a failsafe that is written in the firmware. So that it does not matter what battery you put into it afterwards. That is just is a "WTF! HALT! BSOD " and that this is permanent untill you flash it (because you Clean the flash then).
I will follow your device right away. You gave me hope again
Update 19:26 GMT+1 : I can unlock the bootloader, I can boot in flash mode and fastboot mode, but only without battery.
With battery in it nothing works. Only the red light.
The only thing I can get on my screen is the battery logo, and only if the battery is not in it.
As soon as the battery is in it, nothing works.
I think the Z2 cannot boot without a battery?
update : 20:24 GMT+1 : I read that someone could not charge the phone i normal mode, but it worked in fastboot mode.
So i now booted the phone in fastboot (without battery) and then plugged in the battery while in fastboot mode. The system does not hang itself, so maybe it is charging? Maybe it is not...
I will reboot in an hour and see if I can notice any difference...

I sure hope you'll fix your Z2, this is indeed a weird issue. I can only add that I have repaired Z, Z1c and Z2 devices with heat gun and hair driers with battery inside and never had any issues with batteries, not even weakened capacity. Of course in your case it only remains to exchange the battery for a new one. If that fails then IDK, logic board is next, but that is just not economic anymore. Hope you sort this out, GL

It looks like it is another problem, maybe the logic board
I took out the battery again and measured it using a multimeter. It says 4.3 volts.
On the battery, it says 4.35 volts, so I assume the battery is fully loaded.
I am running out of tricks

And now I changed the battery. Same problem.
Long story short: Some z2 owners around the world have changed the broken LCD screen and now they get the "red light of death" (I googled "changed lcd / digitizer" "red light" and found a few with the same problem. Not just Z2, but also Z and Z3
Its not the battery. Its not the screen (without battery ,you get the battery logo on the screen when you try to turn it on, so the LCD screen works).
The facts :
- 3 flashes when you try to turn on the phone without charging cable + battery in it
- i can lock and unlock the bootloader without problems
- nothing happens when you try to turn on the phone with charging cable in it. (The red light stays on)
- with the charging cable in the phone, you get the red charging light, but thats all.
- holding in on/off + volume up with the battery does give 3 vibrates, but nothing more
- without battery I can flash and fastboot. Without errors. Even the Sony tool can flash the phone.
- if I give fastboot commands I get three dots as an answer and then nothing more. It just hangs there
- a new battery does not solve the problem
- magnetic charger does not solve the problem
- original sony cable + sony charger does not solve the problem
- dock-loader from sony does not solve the problem
- flashing the phone with the oldest firmware and the newest does not solve the problem
- the battery is fully loaded and the voltage does not drop if I measure it during a "power on"
I guess I am out of luck It feels crappy to but a new phone. Not that I cannot afford it, but it feels like such a waste of money.
Another thing is that I really like my dedicated camera button, so I am kinda stuck to the brand too
If any one has any tips, or things I can try, please tell me!
After some more googling, I discovered that there is a japanese version of the Z2. It is called "Docomo SO-03F". This seems to be real Sony (so not a clone). This phone has its own firmware too! Maybe this is the problem? That people with the same problem are installing a Docomo screen in stead of a real Z2 screen?
Does any one know if this could be true? That the hardware is too different?
Just found out about an older post about this phone, but it does not specify about the hardware that much.

No... I hate to say it, but no... :crying: :crying: :crying:
If you take out the battery again. Then you can flash again (holding the volume button down). But as soon as you put the battery back in, it is the same problem. It is so strange.
First I was concinved that it had to do with the battery, because if you take out the battery, and put the cable in the charger (not the computer!), then you get the battery logo on the screen. Do you have that too?

What firmware did you flash? I flashed android 4.x (two different versions). Then I also got no battery logo.
I think the logo is included in the firmware.
When I flashed android 5 again, then the battery logo came back again. Of course, ONLY when the battery was not in the phone. Else I only get the red light.
Android5.1.1 but now when try to flash no reaction when plug the usb cable. Is dead

Try this :
1) take out battery
2) start flashtool (download the latest)
3) hold down powerbutton and then plug the cable in the computer
4) Does it say device connected then? Then you can probably flash it using Flashtool
I assume that you have all the correct drivers (ADB drivers) installed and that you flashed before using Flashtool

---------- Post added at 07:54 PM ---------- Previous post was at 07:34 PM ----------
you buy a new baterry?
Yes. that made no difference
I think this is a firmware compatibility problem. The screen is not compatible with the phone and thus creating a kernel panic on startup. But,Im just guessing. I am sure I did not destroy anything in the phone when changing the screen. I was extremely careful.
Did you also buy it from China. Does it have the Sony Logo on it? (mine does).
There are also version with the sony logo on it, but there is some black stuff over it, that you have to scrape off. Mine was not like that.

Redmi Note 4x 4/64 Mtk - Stuck in the bootloop after battery drainage, cannot charge.

Dear all,
I hope there is someone here, who can help me with my issue. I lost my hope after trying almost everything found in the internet.
So here is the problem: I was using my phone as a navigation in my car. The battery was low, so I used the car charger and kept it plugged, while driving. I observed, that even though I was charging my phone via car charger, the battery continued to get low and finally the phone turned off. After reaching home, I plugged my phone with an original quick charger from Xiaomi. Unfortunately I was not able to charge my phone and it got stuck in a bootloop, with a phone showing Mi Logo, vibrating and switching off repeatedly.
When I connect the phone with the laptop, it is shortly recognized (when it is booting) and then disconnected and again and again. I can go to fastboot mode but I cannot flash my phone using MiFlash, because I get an error: Failed. Low battery.
Does anyone know the solution? I would really appreciate any help.

Are you on miui or a custom rom?
I think I know what problem you are facing, your device's battery is actually drained of all the power, like it empty. So drained that it doesn't even have the energy to turn on the phone to get power. I had a lenovo a560 last year, and it had the same problem, so what i had to do was either leave it for charging and pray that it begins charging (and sometimes after 3 or 4 hours the battery started charging as normal when it got 1% battery), or the second method was that i took the removable battery out and charged it externally using wires. The second method worked since the battery got enough power, to keep the phone on during charging.
Now the problem is that redmi note 4 doesn't have a removable battery, so either you can leave the phone for charging, and actually forget about it for a day, or the only other thing is that you have to visit a service center.
Not joking about the charging process but that is the only thing you can do.

But wait, if the phone is able to stay in fastboot mode, why not charge it there? Like just open fastboot mode, and connect the charger. It will atleast charge some percent.

Hi, i thought about it before, but the phone was staying in fastboot mode for a very short time, to short to charge any resonable amount of power, and kept rebooting quickly. I left the phone for two days without trying to fix it and I tried just now to go into fastboot and try to charge. It stays now for quite a time in fastboot so I will keep my fingers crossed that I will be able to charge. I will update here if it was a success or not. Meanwhile, thank you for all your ideas! Lets see what happens...

Unfortunately, no good results. I kept my phone in fastboot mode multiple times, but I was not able to charge my phone. Turning off fastboot is only causing phone to stuck in bootloop.
I also had an impression, that the phone was not warm at the back, where the battery is. Now I am starting to think that the battery is completely dead and I have to change it. But how is it even possible, that after 8 MONTHS the battery is completely f***ed up?
Can I somehow check the state of the battery? I would like to be sure, that there is no way to bring the battery back to life and I really have to go somewhere to change it. I am really reluctant to have a battery from some unknown company. :crying:

Are you rooted?
This is really a kernel fault man, I had the same issues with mediatek Chipsets before, but you are saying in "8 months", so that means you are well covered in warranty. You can send an e-mail to Xiaomi customer care or visit a service centre with the phone bill. I am pretty sure a faulty battery or such happening can be covered using warranty, plus I would suggest NOT to get the battery changed from a 3rd party store.

Sorry, I actually don't know much about the phones, so I don't know what 'rooted' means. I never did anything with my phone, software or whatever more than required.
With the warranty there is a different problem in my case: I bought my phone in China when I was there for my business trip and I live in Europe (yeah I know, my own fault, I should have bought it at home). I have bill and everything but I guess it will not help. Besides, Xiaomi gives 6 months warranty for battery (in case this is really the battery).

Knowing that you are not rooted is a positive thing when regarding the warranty, ok so here is the thing which you should do. But first of all please stop the battery charging process, since this can now be harmful and can damage the components. Ok so here's what you should do -
[email protected]
Send an email to that address regarding the battery problem. And provide the details including about the drainage of battery, and the methods which you tried. Plus attach the bill also. It doesn't really matter where you bought it, because the bill serves as to give them information that the device you own is actually bought by you, and it contains details about device like IMEI etc. If they respond and say that you can send your device to them, (in this case they will give you an address) you should do that. If they say they cannot help it, then consider getting a repair from a local shop.
I just checked my phone's inside and found out that you cannot externally charge the battery, so this means you need a repair, unfortunately.
Before ending this reply I just wanna clear the fact that,
The battery isn't damaged, it just isn't able to get power,(here it is because of the device) this means that if somehow some energy can be provided to the battery, the battery need not be replaced.
I wish you luck , may you be able to fix your phone again.

Dear all,
I hope there is someone here, who can help me with my issue. I lost my hope after trying almost everything found in the internet.
So here is the problem: I was using my phone as a navigation in my car. The battery was low, so I used the car charger and kept it plugged, while driving. I observed, that even though I was charging my phone via car charger, the battery continued to get low and finally the phone turned off. After reaching home, I plugged my phone with an original quick charger from Xiaomi. Unfortunately I was not able to charge my phone and it got stuck in a bootloop, with a phone showing Mi Logo, vibrating and switching off repeatedly.
When I connect the phone with the laptop, it is shortly recognized (when it is booting) and then disconnected and again and again. I can go to fastboot mode but I cannot flash my phone using MiFlash, because I get an error: Failed. Low battery.
Does anyone know the solution? I would really appreciate any help.

I am still waiting for the response from Global Service. If nothing happens, I will go to local 'mi center', where I know they can repair xiaomi phones, but not on warranty.
Apart from that, phone is still dead, but I have not tried yet anything else. I found this: https://xiaomifirmware.com/guides-and-tips/fix-bootloop-redmi-note-4-mtk/
But I am not sure, if this should work. Anyone have tried?

That post shows you how to enter deep flash mode. You can give it a try. If that works, Voila, If it does't better go the service center.
So I got the response from service (it took them ages). Maybe it will help someone:

I did not try anything from this yet, I have my phone at home, but maybe it will help some of you.
btw. the previous method from the link (deep flash mode) is not working for me.
PEOPLE I FIXED MY PHONE!!! I used again and again this method, which I have already posted before: https://xiaomifirmware.com/guides-and-tips/fix-bootloop-redmi-note-4-mtk/
I didn't work at the beginning, so I left my phone and actually wanted to wait till I go back home to my country for the weekend and visit Xiaomi service, but FINALLY IT WORKED!!! I cannot explained what was the reason that this time it clicked. My phone was completely drained, left for long time without touching. As a result I have a battery icon now and it is charging, no bootloop anymore. Hope this method would help someone. Be patient and try multiple times!
So it is not software problem causing the bootloop
So it is not a software, but only hardware - the battery - as the only problem in this case. I am facing a very similar case with my Redmi Note 4x Mediatek (4/64 Memory) just starting Friday morning (9Feb). I thought it was charging overnight, but in the morning found the power totally drained, and stucked not be able to recharge for hours. This phone is still under warranty (9month use) but ridiculously the Official Service Agent said they need up to 40days to fix this phone. This is worst experience comparing to other phones I ever had.
