Have somebody checked if the M4 Aqua is listed in Sony's Emma tool? Free Xperia Project wrote about this new bootloader from Sony, so we could have direct access to recovery partition (root and custom recovery no problem in this case)
In flashboot mode, Emma tool recognizes my m4 aqua.

The Xperia Z2, and many other Xperia devices, don't have a recovery mode.
In addition to the above post, no model in all Xperia phones with stock recovery menu, it can be installed later after Root device and only then will it be possible to enter the same installed recovery.

Greetings dear xda members,
i've got a sony m4 aqua e2303 from my friend, i cant get out of bootloop, it shows sony logo, then black screen, then sony logo and whole thing repeats forever. It is also getting very hot during this process. i CAN put it into fastboot and flashmode, but when i tried to unlock bootloader by official sony method, it says "remote: command not allowed", but about a week ago when it was working, i checked and it was "bootloader unlock allowed: yes". i know that i must enable oem unlock in dev settings, but i just cant get there since i have a bootloop. flashtool flashing doesnt help, tried 3 different tfts. fastboot works but i cant execute any command.
xperia companion repair doesnt work, "update failed"
any help would be gratly appreciated, thanks in advance
How to get Android 7.1.1 working on E2303 - Update: April 2018
Hi,
i have spent days to finally get my own Sony Xperia M4 Aqua E2303 updated to Android 7.1.1 and it was a pain in the a**. (Android 7.1.1 is in early dev state for the Aqua M4, so e.g. there is no working camera and no working speaker/audio)
Now i write some tips in thread to help others because this thread is the first one the google search found when i looked for E2303 bootloop.
Most time i was stuck in the endless bootloop, too, after i tried to update the 7.1.1. android rom. (Today i have discovered this is because i tried updating from Sony's Android 5.0 stock rom (26.1.A.3.111) to Android 7.1.1, but i have to flash the Sony Android 6.0.1 stock rom first (26.3.A.0.131) prior updating to Android 7.1.1.
After i had the 6.0.1 stock rom installed, i never had the boot loop again. (Expert tip: Prior updating to 6.0.1 stock rom, the sony boot logo was white letters on a black screen, after flashing 6.0.1 stock rom, it's black sony letters on a white background.
Just to mention, the flash of the latest stock rom i have done with the software "Flashtool 0.9.24.4" in so called flashmode.
Expert tip: Always turn on "usb debugging" in developer options
The bootloader of the Xperia M4 Aqua E2303 is locked by default, but Sony have a special developer website where you can generate your personalized unlock code after entering your phone's IMEI number.
I tried unlocking the locked sony bootloader with "fastboot", but no luck (error message was something like command not allowed/unknown remote command). - I also tried unlocking the bootloader with Flashtool, but also no luck at first (some kind of oem error message)
But then i found a hint on some web forum, where was described that i have to create a new folder with my 10-character phone serial number and my personal bootloader unlock code (i get from sony's dev page) in a text file in the path C:\Users\<Your Username>\.flashTool\registeredDevices\<Serial number of your device>\ulcode.txt
So for example i created the folder "YT9114CNHN" under C:\Users\Thomas\.flashTool\registeredDevices\YT9114CNHN\ and there i generated a textfile which is called ulcode.txt and has only my personal unlock code from sony's developers page in it, lets say E8D20BE5BAC1E27C .
With that folder the bootloader unlock with flashtool was no problem at all, and i had an unlocked bootloader. (Just to mention: Do not copy my file paths, your needed file paths will differ)
I also managed to install TWRP in version 3.2.1-0 with "fastboot"-tool. Downloaded a twrp-recovery-image 3.2.1-0 for my Xperia M4 E2303 and flashed it with the command "fastboot flash recovery recovery.img".
After that i was able to boot directly to TWRP.
There are also some "keyboard shortcuts" you have to know when working with Sony M4 Aqua:
Fastboot-Mode:
Device has to be powered off. Then press and hold "Volume up" when attaching a usb cable to start fastboot mode. The LED should light up in a blue color. (Drivers for fastboot mode must be installed inside windows, there should be no question marks in device manager)
Flashmode: (whenever you think you have bricked your device you can flash stock rom with flashtool and it comes back to live again)
Device has to be powered off. Then press and hold "Volume down" when attaching a usb cable to start flashmode. The LED should light up in a green color. (Drivers for flashmode must be installed inside windows, , there should be no question marks in device manager)
Boot to recovery (After TWRP was installed)
Device has to be powered off and absolutely NO usb cable should be attached to the phone. Press and hold volume down while you press power button until display comes on. Do not press power any more, but still hold "volume down" until you see TWRP boot screen.
After that is is simple: Wipe -> Advanced Wipe -> Wipe everything (data, system, cache,) and install the latest 7.1.1 zip, in my case this was tulip-ota-eng.e2303-7.1.1-NOF26V-20170217.zip . After installing cleas dalvik & cache and reboot. - Now Android 7.1.1 should load, but it will take a while, long boot time...
Your integrated chip of your device has been damaged. It is called boot ic. Repair it and flash to latest stock rom. will solve your problem.
Hello all,
I have xperia Z2 tablet which is now dead after I accidentally flash twrp to boot partition.
What I did before I went to recovery mode and try to install TWRP-3.4.0-sc-1_castor_windy_20200606_1419.img but I chose "boot" partition and after restart, the tablet is dead.. black screen and no red LED when I charge it.
One thing is, when I press power button, the tablet is vibrating once then nothing...
Can somebody help how to resurrect this tablet..
Thank you.
Installing TWRP to the boot partition? Why?

yeah, stupid me.. my finger is faster than my brain
the tablet is not responding by pressing power button, so I can't start adb devices nor detected by my laptop
so, what should I do?
if it's hard brick, is there any way to flash using jtag?
Is recovery mode or bootloader working?

It works now,.. yeeeayy
recovery mode is still active, so I use Sony Mobile Flasher tool from the thread and flash the FTF again.. and now working back. Thanks @ze7zez for the hint.
Anyhow, I have second Z2 tablet when I connect to Sony Mobile Flasher, it hangs on "Reading device information". What I did so far:
- Install (all) complete driver from Flashtool-drivers
- try different USB cable
- try different USB ports
- when I try to flash with EMMA, it can't be detected
any thought? Thanks..
