Xperia M4 (e2303) stuck in boot loop- can't get past Sony logo - Sony Xperia M4 Aqua

Here's a timeline:
-Got the phone, worked fine
-Unlocked bootloader, rooted & installed TWRP
-Installed unofficial Android 7 as described here
-After a couple of days I got tired of the bugs and decided to revert to Android 6.
-Installed unbloated rom, can't remember which one
-Phone worked fine.
-After a day or so of use, I rebooted the phone, and it would not go past Sony logo (black text on white background)
Here's what I have tried, in a somewhat chronological order:
-Holding combinations of up/down/power
-wiped dalvik/cache
-reinstalled same unbloated rom
-reinstalled stock rom through Flashtool (tried android 5.0 and 6.0 roms, neither worked)
-Completely wiped OS and reinstalled stock rom- up to this point I could still boot into TWRP
-Relocked bootloader and tried repairing through PC companion (said it was successful, but the phone is still stuck on Sony logo).
This is where I am at now. Any help would be appreciated, if I can provide additional data I will.
Thanks in advance
Edit: I don't know if it is relevant, but the phone always gets really hot- at least 70 degrees, sometimes up to 90 according to TWRP.

If it's stuck on the boot logo it's alive. Can you enter recovery, wipe every single partition and then flash ftf with wiping everything including cust-reset

The thing is, I can't get into recovery through holding the vol up and power buttons. When I do, the phone just vibrates once and reboots (or if I hold it longer, it vibrates 3 times and switches off).
Should I wipe everything through TWRP? Is there a way to wipe through adb?

Hi DavidMKD,
I'd like to answer as well because I'm stucking at the same point but with an E2333.
I've wiped every single partition by TWRP and then flashed with an official ROM downloaded from xperifirm.
No changes at all.
I'm wondering it is hard issue, maybe changing the battery ?
It is true as well that the side under the back camera it's very hot when the phone start.
I didn't find any advices works. The only way to talk correctly with the phone is to flash it or root it, then any OS are unusable, in my case 5 mn max.
If I can help to have another try in your experience...
Thx in advance

Hi guys,
I think I've found a turnover to arrange everything, described in a thread :

Hope it helps

[Q] Xperia Neo stuck at "SONY" logo when boot into CWM recovery

Hi everyone. Can anyone help me figure out what's the problem that i cant boot into CWM. I have Neo MT15i running FINE with stock rom ICS .587, locked bootloader and rooted. I also installed x-Parts as well as CWM 5.5 and busybox 1.20. But my problem is that my phone just cant boot into CWM recovery no matter what i did either press and release volume - continuously when "SONY" logo appears, or using x-Parts function to boot into recovery. It just ends up stuck at "SONY" logo (I waited for about 10 minutes but no respond)
You have to press Back button while booting from Sony Logo to boot into CWM.

same problem for me...xperia neo v
Hello.
I have a similar problem, if not identical. I rooted my MT15i today hoping to install a custom ROM I found in this forum.
Everything went fine. I rooted the phone and installed Clockwork Mod Recovery properly.
Then, I downloaded the rom .zip, placed it in /sdcard, made a backup of my current system, wiped data/ full reset and installed the ROM with SUCCESS, as it said in the log.
After that, I rebooted the phone and now it keep stuck in the "SONY" boot screen and won't change no matter what I do.
But I think I know why did this happen. I was following a tutorial found in another site. There was listed only to wipe data and full reset, and not to wipe danvik and cache, as I came to read after I was stuck in the boot screen.
The problem is that now I can't even get to the Clockwork Mod Recovery screen, even if I start the phone holding volume down button (or reset, or any other button the phone might have).
The only thing to do is removing the battery. After starting again, it gets stuck again in SONY screen.
When I plug the phone into my PC, nothing happens. It doesn't get recognised.
It only turns on and stops at the SONY screen again.
I wonder if there's a way to access the Clockwork Mod Recovery menu or some way to return the phone to the stock settings.
Or is it a possible brick?
Thanks for the help already.
Ps.: sorry for the long post.
First of all don't worry your device is not broken
And not every custom Rom support locked bootloader
The reason you can't access cwm because you wiped data
I think you can restore your phone by reflash firmware using flashtool

I can get the phone to conect to the PC in flashmode. I downloaded the stock firmware of Neo MT15i (v 4.1.A.0.562) and flashed it, but no luck. The phone keeps stuck in the SONY screen. Any ideas?
EDIT: actually, when I bought the phone, it came with Android 2.3, I don't remember the firmware version.

It doesn't matter which android version you flash all should work
make sure you checked those boxes in flashmode
Wipe data
Wipe cache
Wipe apps log
No final verification
And just to know when you flashed the firmware. Does it completed successfully?

Well, I got the phone to boot. I was just trying to flash an incomplete firmware, I guess. I downloaded a new firmware I found in a rooting tutorial thread in this forum and flashed it. The phone is now working fine.
But now it's not rooted anymore. Maybe in the future I'll try to root and flash a new rom.
Thanks for the help, anyway. :laugh:
Never mind, but I suggest you unlock your bootloader if you would like to flash custom Rom

What rom were you trying to install? Is your bootloader unlocked? And you can try flashing stock firmware with flashtool to revive it...

NEO V doesn't boot
Hi,
I installed following in my Neo V MT11i
Super Jelly Bean v6.0(16th august 2013)
best kernel for sjb(fusion 5.4)
debloated updated gapps
using following link . http://forum.xda-developers.com/showthread.php?t=2108632
I am using Kernel_Flasher_v2.0 to flash the image kernel. It recognises the device and shows that the kernel is flashed. But the device doesnt reboot. I root the phone through eroot software. Then I install X parts and go into recovery mode.
I wiped the phone fully, including system format.
Please guide where I am missing some crucial step.
I am using windows 8
Thanks in advance

[Q] Stuck in bootloop and recovery vanished

Ok, so something seems to have gone very wrong with flashing my phone :S
I managed to get recovery working yesterday, and followed the steps in this thread, http://forum.xda-developers.com/xperia-z2/general/4-4-4-creating-rooted-update-package-t2933155 , to create a pre-rooted 5.0.2 image. I put it on the external SD card, booted into recovery and installed the flashable zip, then used flashtool to flash with the instructions (though I also cleared Appslog, Cache and Data to get a fresh install). This went fine and everything appeared to be ok. I then tried to get the Xposed Alpha installed, but after that whenever the phone was rebooting it just hung if trying to boot to Android. I tried re-flashing with Flashtool, but still got the same issue. Would boot fine the first time, but then any restart it would just hang and crash out. Tried clearing the cache from recovery, but no difference.
So today, I went into recovery, re-installed the flashable.zip, then powered off the phone and flashed using flashtool, just as I had yesterday. Now though, my phone wont boot. It shows the Sony logo, then a blank screen, then restarts. Even worse, it will no longer boot into recovery. I hold the volume down button when the LED shows, nothing. I try holding the volume down button all the way through several bootloops, nothing.
I've tried to re-flash using flashtool which goes through the process ok, I can hold the volume down button and connect the cable once its in the process of rebooting, and it goes through all the process fine. It then powers off as expected and I can just disconnect and power on the phone. But it's still stuck in the bootloop and I don't have TWRP recovery.
Is there anything I can do to get my Z2 working?
Update - Re ran flashtool, this time not excluding system, only Partition. It now gets a little further, going to "Powered by Android" and giving the purple wavy lines, but after a minute or so it just hangs and restarts again. And still no recovery sadly....
I think I've got it sorted...
Used Flashboot again to do a flash, excluding System and Partition. This time the phone does boot up normally. The downside being that my root was gone. Despite my flashing a pre-rooted image, it seemed to just put a stock image on. And my recovery is still mysteriously gone.
In the end, just to get things completely back to a stable/stock starting point for later on, I ran a repair from PC Companion. Seems I was in the none rooted position anyway so figured I'd get myself to a more certain position. At least this way I can wait for someone to come up with a root for 5.0.2 so I can root and get recovery back.

bootlooping, USB debugging off, looping at Sony logo, have only cynagenmod recovery.

Hello everybody~
1. Xperia SP
2. BootLoop
3. Can't get further than Sony logo (it keep restarting so i assume I can't get to recovery screen)
4. USB debug is off
5. I dont have CWM, the last time i see my recovery screen is the cynagenmod recovery.
6. Now I had a problem turning it off...
I would hope to get the phone back alive, if not then at least retrive some of my files from the inner storage.
Worst case, I believe i can bring it to some techs who will break my phone to get the storage physically to do transfer. (not sure if that works??)
additional details:
I flashed a firmware which is by right the firmware for Xposed, xperia SP and that started the boot loop.
At first it can reach the screen of cynagenmod but it kept flashing for an hour, which i concluded that it is a bootloop.
I had wiped the cache partition as well as selecting the factory reset option in the cynagenmod recovery.
I flashed XperiaSP_C530X_12.0.A.1.257_KernelOnly.ftf using fasttool and from then on, bootloop had leveled up, and cant get pass Sony....
Thank you everyone!!
I forgot to thanks in advance~ hahaha
Flash stock ROM mate, always when that happens flash stock ROM. Did you even read before posting?

Soft brick - stuck on Sony logo

Just gonna cut straight to the point.
Wiped my phone to flash a new ROM, selected 'Clean to install new ROM' but instead of then flashing a zip file, i went to Reboot Recovery.
I then hit No, thinking it would take me back to the main menu, but instead it continued to restart, and now it gets stuck on the Sony logo.
I've tried flashing completely stock ROMs and also this one which, those with similar issues has said worked for them, however nothing appears to be working for me.
It does seem to flash successfully, no error messages that i saw in Flashtool, but upon booting up it still get stuck at the Sony logo. Either just Sony (older ROMs) or Sony with Xperia at the bottom (newer ROMs), so i guess the ROM is installing fine, but there's something else that isn't?
The only way to shut down is holding down Power + Vol Up, and there is no LED light (green, purple, red) to notify of anything.
And because of this I no longer have recovery either, where I could just flash a new zipped ROM and be on my merry way.
Any suggestions?
EDIT:
Ok so I hate when this happens, where I figure it out a few mins after I'm made a post (after stuffing around for several hours already).
I've just tried flashing several different ROMs again to no avail, tried once more and checked the two boxes in the Wipe options, seemed to take A LOT longer to flash, but it's now working fine
flash any ftf or chech here

I also in this situation. I cannot go to recovery and stuck at boot logo. Can you point me the right direction? Thank you.

stuck on boot animation. cant go in recovery

i had my amaze repaired (power IC, bad data cable caused it to not charge or even boot up or go in bootloader). Now within 30 seconds off booting up it used to restart. and i cant get into the recovery( shows logo and powers off when going into recovery from bootloader). i cleared the cache from bootloader and its now stuck at boot animation( not boot logo) and wont boot completely. before clearing cache after logo it used to show 4ext recovery boot screen then screen off, now it just shows logo and screen off. really need help i got this phone fixed after 1 year. im s-off and running any 4.4.4 rom (dont remember which rom, i think pacman rom)
so basically i can get into bootloader and use fastboot commands (no adb, authorized device). cant do anything else on the phone. is there a way to fix the phone?

reflashed recovery for the 4th time and it worked. it said the cache partition is corrupt. formatted it. phone works now. updating apps caused system ui stopped working error. going to flash other roms.

Glad you got your phone working--your persistence paid off.
Be sure to make a backup before flashing other ROM's.
