[SOLVED][Xperia M4 E2333] - Startup Logo bootloop or Android continous rebooting - Sony Xperia M4 Aqua

Hi all,
after 3 days of searching, maybe I've found something sounds good, but I'll stay in test mode for a while and I'll keep you in touch in case it is really stable.
What's happend :
3 days ago I did a simple ''factory reset'' and since then I experience a continous reboots after a minute or two alive in Android official 6.0.1 and a bootloops when processor cames really hot.
At this time on internet you can find lots of people with the same issue and all of us without any solutions at all.
Now here the list of my tries :
- Did again a ''factory reset'' with Sony companion and Sony flashtool Emma : no changes
- Call Sony for support? Warranty still okay? : do not waste your time, Sony wants your money and thats it ! (take a try anyway, you will see by yourself)
- So let's root the phone! Even if you do not know what to do, you can find looots of Tutorials and lots of very geek competent guys to help you (better than Sony support anyway), thanks XDA Developers !!!
- Even if I've completely erased all partitions with TRWP, when flashing and back again in stock Android with xperifirm : still no changes !!!
Now, during those tries I've noticed that the temperature of processor is dangerously high, and that for every startup process.
You know, at the end I think that the bootloop (I guess in that case only) it is made by temperature mainboard automatic protection.
Anyway, before to play freesbee with and go to buy a new one, I've tried to :
- open the back side (very simple but all operations should made very carefully)
- unplugged the battery for 15 minutes
- take off processor's metal protection to avoid heat retention
- plugged the battery again
- close the back side and started Android
Since then the phone is still alive !!! Just working as it should...
I'm trying all I can do to stress it to see if any problems happend again, installing back all apps, using Root features to uninstall useless Google or Sony apps, restet the phone several times.
The processor still heat up every time you do something or restart, but I do not experiencing sudden rebooting or bootloops again at the moment.
As far as I'm concerned, I would say as well that it is a processor issue, but I'm not a scientist, so I guess this apply to different Xperia models and not only to M4 Aqua Dual.
DO NOT FORGET that this is not a real solution. I just did the only thing that you cannot normally do with that kind of phone : unplug the battery.
I hope I can give some good ideas to all of you, or maybe a good way to a solution .
Happy to share,
Flaximuss

More information please
Well, now I'm sure it is hw problem.
A guy solved this doing some trick:
www(dot)youtube.com/watch?v=mgCSPAmJld4&feature=youtu.be
and it works pretty nice, for a while.
I'm more interested in your solution, how far it didn't bootloop, etc.
Could you tell me how is your phone doing?

I betrayed my Sony Is there any way to bring it back???

So, I will explain what has happened.
I received a Warning Statin "Unfortunately, Hike as stopped" followed by "Unfortunately Google has stopped" "Unfortunately home has stopped"...
So I shut my phone off, which I used to do every time and restarted it.
My what happened next is something I haven't experienced before.
My Xperia, just displayed "SONY" logo and nothing else. I know to flash and I have done that many times before. So I was lethargic that I could easily bring my sony back to the world. but that didn't happen anyway :crying: :crying:
I read so many threads in XDA but none of them could have faced what I'm facing. Coz my Sony Xperia Aqua M4 will not vibrate so I couldn't able to differentiate Hard and Soft boot.
After waiting for a restless 24hours I tried to open my Sony Xperia Aqua M4 that's when the real problem started...
I found a video that if we remove the battery and reinsert it then everything will be fine.
so, I removed the back cover.
Flip opened that Copper Layer (I really don't know its purpose though) and unplugged 3 battery plugs. That when the things began to get out of my hand.
After reinserting the plug I started my mobile once again only to see the Sony Logo and not the blue waves. So I tried to restart the mobile by pressing the Rest button near the SD Card Slot only then I came to know it stopped working.
So once again I unplugged the battery and this time I had that copper layer trimmed and replugged the battery.
And this time no Sony Logo too :crying: but I could feel the temperature of metal on the board rising to its peak. I don't know what to do...
Is there a way to make my Sony work again?
Pieces of Advice Please.......

Temporal solution
If you don't want to disarm your phone I got one solution:
1) Press the screen with your thumb and the back panel with index finge, near the nfc logo
2) At the time of starting it helps sometimes.
It is an hardware problem.

The solution worked but...

Hi, the phone has started up, however, is there any way to make the solution last?
Please it would be really nice that there is a chance to recover the phone.

Of course there is a way to save your phone, but nowadays the process cost more than buying another M4 AQUA used. You can do "reballing" or a little "reflow" in any refurbishing store if you want but I recommend changing that phone. It is not so good to use mate.

[Q] Random Reboots?

Have you guys ever experienced your x10 randomly restarting itself? Sometimes when I'm talking on the phone or just have my phone lying on my bed, it just restarts itself. I doesn't bother me too much since it isn't that frequent, but it pisses me off when it does restarts while I am on the phone...
Does anyone know why it does this and how it can be prevented?
Hi shukla,
I've got exactly the same problem! Which firmware is on your phone? I've got the 026 on my X10i. I think it's the firmware or the new root method?!
If I'll find some time this week I would like to try some things out...Some other experienced that problems, too?
Regards,
Martin
I've had random reboots as well running 26 firmware (using the 3 step root method) thankfully never during a call last time was while in Toronto this past Saturday taking pictures with Vignette.
I'm on 024 (rooted).
I think I was wrong with my thoughts. Today I've read a lot about our problem with rebooting. Seems it is the Sony backup application. It is randomly accessing the SIM card and thats the reason why our phones crashes. Right now I am going to flash my phone again. I'll tell you some more details after flashing is done.
Ok, well it's not easy to fix that problem. Yesterday I flashed my X10 about 6 times. With original SEUS firmware and the problem still appears. Then I flashed with 026 debranded firmware. After that I rooted my phone with the doshaska.net method. After that I removed the restore/backup app from /system/app. The problem still appears till now - but not so often. In fact, I had reboots every minute, so my phone didn't came up. I really don't have a clue why it happen. Someone else got an idea?
Regards ,
Martin
The only way I could stop mine from rebooting was to remove SetCPU. Are you using it? If so, feeze it or remove it and see how it goes. I do have another problem now with the damn screen not sleeping unless i push the power button! Oh well, the joy of fiddling
Nothing out of the usual battery dain yet. I am running the branded Dutch t- mobile firmware. I'm going to root it soon.

alright i found the solution myself...this post is just to help others
flashing did not solve my problem at all, through SEUS or rooting method nope the problem didn't go
finally i removed my memory card and everything was fine
some things on memory card could cause reboot during calls or randomly, next time try formatting your memory card
hope it help someone
cheers!
luv my x10 though i ve also got iphone but i ve never looked back
Just curious, how hot is everyone's phone when it reboots? I've noticed my x10 doing the same when its running a little warm. It usually starts acting up when it's over 105 degrees Fahrenheit.
Sent from my HTC Desire using Tapatalk
Gitin thx..it looks much better now, however yeasterday I was carrying my x10(still with no memory card in it) in the pocket, it got pretty hot (most probably over 38 degrees) and it turned into this rebooting "mode"..finally I left battery for 20 minutes in cold place..x10 got back to normal..I think that random reboots are the matter of memory card issue (You have solved this problem) or/and overheating of battery - still couldnt find any clue how to ease this pain but read somewhere that Froyo for x10 will have this problem taken care of..
i think ( depends on my experiences) the telephone need to reboot coz one applications from SD card want to launch (send or receive) some commands from or to internal (built in memory).
that's means this applications needs to move temporary to internal memory just to execute this command so absolutely android system will restart to create virtual memory to this application to let it runs correctly
first it's better to remove backup/restore programs or make its runs manually, if you have another software need to save data to SD memory ,remove it.
it's better to launch applications directly from internal memory to win the time and performance but At the expense of the memory size
ps: all that explanations depend on the framework version.
sorry for complex explain but i don't have easy way to explain this problems
i suddenly have it now to, first every hour, now every 5 minutes, my phone won't start up anymore
sorry..bad news..its pretty cold here in Poland so battery shouldnt turn to hot that easily but apparently the problem is more serious..I have to admit that random reboots occur less frequently than before but that **** still hapens to my x10..after no more than 2 days I had gotten memory card removed it got back to malfunctioning again..
it really pisses me off that I cant enjoy this phone anymore..
android 2.1 or higher is my only hope..
if anybody solved that issue entirely..please, dont be shy, do not hesitate..help us, please!

i too am hanging on for the 2.1 update to hope it solves the problem. I've a feeling there's going to be a lot of x10s going into SE for a service though when it is released and doesn't solve the problem!
I'm not 100% but is this problem the entire phone powering down, or just the connection to your network, mine just loses its network connection and then connects again, over and over ........
there's nothing 2.1 update will do
as our phone was working fine when v bought it, its completely a hardware fault
ok do this...
1.take out sim
2.format ur memory card
3.repair through SEUS or root process watever..
4.turn on ur x10 without sim and leaving formatted card inside
it will still give u hard time u can try putting some video on ur memory card and try to play it few times, ur x10 will turn off and wont turn on until u take out battery for few seconds or take ur x10 in front of Air-Conditioner
as someone suggested in rooting thread to keep ur x10 in front of air-conditioner if u get errors while rooting or if rooting process stucks in middle
the same thing applies in our case...try using ur phone in front of A-Con it wont turn off
i tried with a new battery ...still the same
as i ve been repairing mobile phone from last 5 years, i opened my x10, took out the motherboard, took out all plates over IC's, cpu and cleaned it with acetone properly and heated cpu and whole board with Hot Air Gun...everybody who repairs mobile phones knows what i am talking about
still its the same....
still i am not saying i know everything, anybody knows what the problem is and suggest the overcome is most welcome
nxt few months gonna b really cold at my place...i definitely think i'll notice a difference as its really hot these days which is causing my x10 to die
I did experience this when I debranded my AT&T X10. I have since gone back to the AT&T ROM and have not had this issue since. My battery life has also improved. I did root and remove all the AT&T bloatware. I also edited settings.db to allow for installing non-market apps. This phone is very fast and smooth now with almost no glitches at all.
mine won't even work anymore..once per every 20 or 30 times and than it turns off itself very quick..I can't recharge battery, nothing..really hope that 2.1 will help somehow..I am thinking of getting back to very first soft that x10 was launched with..seriously I am sickin tired with that ****..

Hi, I have an AT&T X10 and wonder what you debranded your phone to? I debranded mine about a week after I got it to R2BA026 Latin America and never had any issue with rebooting.
Aside from needing to power off the phone to check for software updates (two weeks ago of course ) my phone has been up for +358 hours without an issue, and that's with installing the AmbientTime home screen several days ago.

[Q] Restarts.

I have bought xps about 20 days ago. Yesterday and today , while I was surfing the net via wifi (both times) , my phone suddenly switched off and made a restart. Did anyone experience a problem like this ?? It never happened before.
Not had that problem - infact I was just thinking today that I haven't restarted my phone for a week.. and it still feels super smooth... which I've never experienced before on Android!
Never had a sudden restart, lag or unresponsive device. Seems that you are the only one here with such a luck...
Is this a reason for returning my phone to Sony? Is sony obliged to replace my device with another one?

Unfortunately sudden restarts are very common in the android world. I think 80% of the android smartphones had at least once this problem. You should wait to see if it happen again and if so try a hard reset or a software repair using sony pc companion. If it will become a common problem even with other users sony with a future update it will fix the problem. What software version do you have .62 .67 or .73 ?
Hi,
If you have this reboot issue
Nothing can resolve this!
But,just in case
Do not use your phone with charger pluged in for long time!
This kill your battery very quick!
And cause autoreboot
And be careful with internet!
If you flash some FW or rom or kernel
Made a full charge before flash

I've had this happen to me on my Xperia S twice already while using it.
It also randomly restarts while in standby once in awhile.
Not sure what's causing this. Any suggestions?

If it's not happening very offen like twice a day, the only thing you can do is wait for the 4.0 update, because If you look in all the other android smartphone forums you will see that every android model have this issue from time to time. I think is something like the Windows OS bluescreen...very very difficult for normal users to detect where is the problem. I think with the 4.0 update the problem it will be solved. But if the Xperia S become unstable and randomly rebooting every day try a software repair with pc companion and if this is not solving the problem just go to a Sony support center and give them the smartphone for replacement.
I have the reboot twice
Refresh ROM good!
Hi, my phone also has random restarts. It becomes sluggish and unresponsive, then just restarts.
I think mine has done it once or twice when just in standby mode as well.
I actually got my first Xperia S replaced as it had this problem, but the replacement is also suffering from it.
Seen a few other people saying they have the same over on the Sony forums, so I think its a software problem somewhere.

I have .73. I didn't flash my device nor I use it when charges(and I don't let it charging for hours).
I think that there was not enough RAM at that time but I am not sure. I'll have to check it out.
I just experienced the same problem not too long ago. I was web browsing and my phone crashed and rebooted on it's own. I'm on the phone with Sony right now because I have the youtube issue as well. This sounds like a software issue.
Had mine since March 6. So far only one random reboot, none since update to 6.0.A.5.6
Sent from my SO-02D using xda premium
I called Sony Mobile Canada to report this issue. I told her others are having this issue as well. She's going to escalate it. I would like to encourage everyone who's having this problem to call Sony tech support in your Country and let them be aware of this issue. The more people call about this issue, just maybe they will work on a software fix sooner rather than later. Strength in numbers!
No restart on mine
I heavy use internet 3G/wifi on it
But,
I never flash anything on mine with flashtool or seus or pcc
Pure stock FW.67
12w14
AAD-AV
Only 2 "big" issue
Phone freeze one time
when plug charger in
VolumeUp+power solve the bug,
And the yellow tint on the screen.
Normally,when the phone keep autoreboot,or autopowerOff
It is caused by a dead battery
You can identify it
by keep hold power when the phone restart by itself
and at reboot
If the led blink 3 time red when holding power
That's indicated battery die
Or made a battery test in service *#*#7378423#*#*
But your phone is new !
So try a full charge with reset battery to get best power (volumeUp + power 5second one vibrate)
If your phone is rooted
you can delete manualy "power_supply"
in sys/class and reboot
with charger pluged in
After that,
try a full restore with seus with wipe data ect..
Can't help more :-(

Of course it getting hot.
Power means heat...
Logic.
This isnt a overclocked pc with grammacs core mg..
Kills battery and reboot. Right. Your right.

Hi
What do you want to do?
If your screen is broken, you could "do" something via ADB, but not so much.
PERHAPS you could delete your lockscreen (you can do, search), make the device boot wisthout sim cadr (=no pin), install (adb install) something like airdroid or similar (i do not know such apps), launch it (inside ADB with "am" + something) and hope you can "use" your phone via PC.
Ok looks more like SCI-FI!

My friend has a Mini Pro with broken lcd , he broke it 6 months back but he still manages to use till now with out any problem....
try flashing custom kernel and a new ROM , If that doesnt help.... u have to go to customer care..
Re:all
thanks all, but i'm sure that lcd is fine (maybe), because, before that (suddenly restart) my phone is allready fine with all function normally (although my lcd is broken but touch function is normal). until restart happen, my phone was not start up again. in lcd i see blank, no logo and anything. just vibrate 2 times. in that condition i think, i can make a call for test but the warning from sim operator said that my phone was turn off.

for Publiuss, i hope you can give me tutorial how to controllling my phone via pc in condition my phone like now.
maybe use the usb cable to know that my phone (until flashing rom or kernel) was working or not, and if i can getting that, means, my phone trouble in lcd.
i will keep out for cust care if i can solving my trouble by self, because maybe if i have to go cust care they will charge me cost not much different with new buying this phone.

Well Man i say is not software problem. If you flash stock firms, custom roms and kernels you manipulate all the system if the phone dont turn on is a ardware problem. Search a tuto how to open you phone and see if dont have nothing wrong. The conection screen "flex".you see all ok buy a new screen on eBay. Try. After all that phone is very important for you.
Press thnks if I helped to your mind.
Sent from my SK17i using xda premium
actually i had the exact same (or similar) problem after 6 months of ownership.
1) broken screen, dropped phone several times, everything still works no trouble
2) random restarts
3) boot problems, restarts got more frequent
4) can no longer boot, only a lit black screen, no SE logo
Does that sound familiar?
I understand it could be a HW problem but the only thing I can think of is the digitaliser/screen. Try to replace that and see far you get, you can find a replacement cheap from ebay (they come free with tools) and also disassembly guides are on ifixit
please post your results!!
Mini Pro screen is really vulnerable, so even a little defect can cause further issues.
I had a Mini Pro which its screen cracked when I dropped it, it was fully functionable for weeks then one Friday touchscreen didn't response anymore.
I visited a technician and paid about 4,000 Philippine pesos to get it fixed.
Second defect happened after I came back to Korea, when I dropped it toward the wooden frame of my bed.
At first the screen had several purple horizontal lines, then soon it completely blacked out.
It still exists inside my drawer, and since I loved its keypad, I recently ordered $20 screen set in Aliexpress.
I have a question: Did you fix your device after writing this thread? Was the problem related only with the screen?

M4 Aqua - Blue screen / boot loop?

Hey all,
My gf has an M4 Aqua.
She has never done anything with it.
No root, no custom roms etc.
Suddenly today phone shut down, Sony logo appeared, blue booting waves and then just pure blue screen.
She did the Software Recovery via Xperia Companion.
It booted normally, she set up everything (although she said it was running very slowly) and while she was just in the home screen it shut down again and did the same thing.
She clicked the red reset button and it booted fine.
Edit: Shut down and blue screen again.
Edit2: After Software Recovery she is on 6.0.1 now.
Edit3: Even when idle it gives the blue screen after some time.
Any ideas why that is happening, how to fix it permanently?
I've seen posts but people said the Software Recovery helped them which is sadly not working for us.
We just need to wait till next month so she can give this one for proper service check.
Is this a hardware issue? I've never encountered a pure blue screen on Sony before.
Cheers, thanks for any help.
Hello friend, i have an xperia m4 aqua dual, same problem than yours, already used xperia conpanion 3 times trying to solve the problem, the cellphone works like a charm for 10min and the problem gets back again, blue screen if i launch some app like facebook and running slooooow, i have read that this is a hardware failure, but don't know what is the ic failure.
Edit: Now i found the problem, the xperia has 2 module of 1gb of ram on the motherboard, when the phone boots (congrats no blue screen) you can go and see how much RAM it haves, it will just show 883mb of total RAM. so... 1 module of RAM is dead.
Edit²: Saw on the xperia forum that sony is pushing an new update on xperia companion, solved the problem of ram and blue screen for some people, i will give i try later today, can be just a software problem.

Hey mate, thanks for the reply!
Will check RAM and try the Xperia Companion again. Gonna update soonish with the results.
It happens alike, ram, blue screen, and in my case at first had problems with the network signal (it was for a while), and the camera (worked sometimes in or out an error log . So YouTube I found this:
Apparently there is a problem with this smartphone after a period of use, and seeking information on the internet apparently called blue screen of death, and happened to the iPhone 5 and even g3 lg, but in this smartphone presents with different symptoms. Unfortunately in my case it is out of warranty two months ago
By the way the new version of PC Companion commenting here will not let me install it, I get a kernel32.dll error in Windows, but the previous version if you install without problems, someone knows what is due?

Thanks for the vid. Good to know it's kind of popular. My gf gives it to service today so we won't check ram etc. But ye this is a bit of a ****ty phone.
These memory problems, speaker broke now this.
I hope they gonna give her a new one.
Also check a statutory warranty (i think that's how it's called) in your country.
Here in Poland apart from the producers warranty we have a warranty from the seller. (its a law)
If seller sells us a product that breaks (no matter if it's producer fault) they need to repair it or exchange for a working one.
This warranty is valid for 2 years.
i updated my xperia m4 , the problem got worse, can't pass the blue screen now, just a constant boot loop of blue screen, i never want a xperia again --'

We did it with Xperia Companion which is the same **** as far as I know.
The phone is sent to service, she'll probably get a new one.
Thanks for the tip though!
Had the same blue screen after installing a incompatible xposed module. But i had not that ram problem. It sometimes booted and sometimes reboot at bluescreen. Re-flashed firmware using newest Flashtool (include "wipe Sin, wipe Misc TA") blue screen was gone.

Hey all, i had same problem with my M4 before, blue screen, ram just read 883 mb, suddently restart, n very difficult to turning on.
I get problem after upgrade to marshmallow. I have been tried to reset, flash software, and downgrade, but my M4 still problem.
But now the problem has been solved.
Root cause of problem on my device is bad emmc connection.
I found it when i tried to hit my m4 caused felt angry, but my device be normal.
So i tried resolder the emmc n test.
I don't know what the related problem bad hardware connection with upgrade software, but that's actual root cause the problem on my M4.

Please help me!!! If possible!?

Hi, I bought a ZTE K92 (AT&T Primetime) tablet new and unlocked on eBay back in June 2018 for $149 and did not open it up or turn it on/set it up till just yesterday (10/6/18) because of a move to a new residence and I kinda forgot about it since I do have quite a few other devices and it was packed up in boxes I just never got to unpacking until recently. Anyways... I was hoping for a good experience since it had received good reviews and seemed like it was a fairly high speced tab, it is a nice device, unfortunately, at&t screwed it up with A LOT of they're bloatware apps, one named as "device help" continually reloads an icon on the home screen EVERY time I unlock the home screen! I've removed it a kajillion times and tried like hell to disable it but it's greyed out, tried to remove at&t associated files through my file mgr, but to no avail since I don't have root access. BUT... These are minor problems!...
MOST DISAPPOINTING/DEPRESSING is that I have *thin black/grey (depending on the background colors being displayed) lines on the entire screen/display, in normal (vertical) view mode the lines are *horizontal*, in landscape mode the lines are *vertical*, AND... they pulse on/off at a steady rate , as if it was related to the clock but at a slower rate, approximately on for 2 seconds, then off for 2 seconds continuously.
It has done this since first starting the tablet up new out of the box!
I have searched hell and high water to find the cause and or a fix, I've tried apps for screen issues, I've tried restarting, I've tried YouTube videos on how to fix, but nothing has worked and what's worse is i have not been able to find ANYTHING related to my exact problem, only problems with flickering or colored lines on they're screens!
The closest thing I found in relation to my exact problem was certain screens made for Lenovo tabs/laptops, but I don't think the ZTE K92 tablet has the same display as those devices?!?
I have not done a factory reset or a partition wipe as I don't think it will solve the problem.
I DO NOT really want to take the tablet apart to mess with the screen ribbon cables!
It's running 7.1 nougat stock, and I have dev options enabled/on, I've tried different settings under drawing and hardware acceleration settings but it had no effect.
I was wondering if there's a way I could get the tablet back to marshmallow O.S. for a fix, but again, I don't think that would solve the problem, I'm pretty sure it's a hardware/setting or calibration issue.
I did not find or attempt any firmware updates as I'm worried if I do and it doesn't solve the problem, I might not be able to undo the update, and I'm a firm believer in NOT updating, a don't fix what ain't broke kinda thing, yeah I'm old school.
In my opinion, I think it is a screen digitizer issue and I honestly don't know if there is a fix for this AND if I could find a *qualified* technician to fix it!?
This is really very annoying and sucks!
Is there not a single sole through XDA that knows about this type of problem AND MORE IMPORTANTLY, does anyone know how to fix it!?
P L E A S E ! ! ! This is such a shame for this tablet as it is a really nice device.
