Xperia E4 Dual bootloop

Hello, I've tried posting my problem elsewhere on xda without response so I'll give it a try in here. My phone shows the sony logo then reboots infinitely after rooting it and I searched everywhere for a solution but all I could do is get this message on flashtool:
06/056/2015 17:56:00 - INFO - Loader : S1_Root_2f8b - Version : MT6582_15 / Boot version : S1_Boot_MT6582_TC9SP_11 / Bootloader status : ROOTED
06/056/2015 17:56:00 - INFO - Transfer buffer size : 262144
06/056/2015 17:56:01 - INFO - You must have the according fsc script to flash this device.
06/056/2015 17:56:01 - INFO - Flashing finished.
06/056/2015 17:56:01 - INFO - Please unplug and start your phone
06/056/2015 17:56:01 - INFO - For flashtool, Unknown Sources and Debugging must be checked in phone settings
It should be a driver problem but I have already installed adb drivers, specific drivers for e4 from sony website and flashtool, fastboot and jdm drivers from flashtool. I also tried switching usb ports and trying on other computers with the same results, and I'm 100% sure unknown sources and debug mode were checked last time the phone was in working condition.
I tried installing all drivers from flashtool's driver folder as well, still nothing. I dunno if it's relevant but the device is recognized as somc flash device in device manager. I'm using flashtool 0.9.19.0 as I read somewhere it works better for the e4 dual (even if it doesn't for me) and the latest version gives an IO exception error.
Any expert who can help me with the problem?
Edit: Bootloader is unlocked but the problem was the same before unlocking

Is there really no way of fixing my phone? Please help. . .

Anyone?

Can someone enlighten me? Now the battery is dead too... phone won't charge anymore.

too bad i didn't see this thread previously.
hello friend,
I too have the same problem now.
i tried to change the build .prop and ended in bootloop today.
i have a similar message
"16/028/2015 15:28:57 - INFO - Please connect your device into flashmode.
16/029/2015 15:29:08 - INFO - Device disconnected

16/029/2015 15:29:50 - INFO - For 2011 devices line, be sure you are not in MTP mode"
I tried to change the usb debugging settings through adb ,it is not working.
the internal storage and sdcard are not mounting. :crying::crying:
I think we will have to get help from sony support and the thread Xperia E4 Development by LeonXperiaXC
Did you try out the sony pc companion ? it is supposed to work as my device has a locked boot loader . but it is not working either.

Yes I did that, device not supported, and that was even before I unlocked the bootloader.
I gave up fixing it some days ago, seeing that neither sony nor xda helped, and I can't afford a new one for now. Please let me know if you do manage to fix it, as I will check here from time to time, good luck to you.

As i couldn't fix the device,I gave the phone to the service center.they had fixed it .I will be getting the device on moday. :fingers-crossed:
By the way,i found some interesting fact why unbricking didn't work for our E4.
sony pc companion unbricked my previous device xperia E1,it is a snapdragon device.
I think mediatek devices can't be unbricked by sony pc companion and also flashtool by androxyde.
Xperia C cannot be unbricked by the both as well.it is a mtk 6589 device.
Xperia C has an unbrick method using a tool/software called WMshua perfect flash.
https://www.informationlord.com/ultimate-guide-to-fix-bricked-xperia-c/
I didn't try it because i was scared of hard bricking the device.
I think it might work.
plus for chinease mediatek devices there is another tool called spflashtool.
also learn to use the spflashtool .there is a begineers guide at mtkroms.com
http://www.mtkroms.com/2015/02/how-...howComment=1447795342637#c6494565355265496004
give it a try.
If you have warranty definitely get it repaired by the service center.
or try the above methods if you have no choice.
I hope you will get your device working as soon as possible. :good::good::good::fingers-crossed::fingers-crossed::fingers-crossed:
Good luck.

force locked bootloader by lenovo care center

Recently I have owned lenovo zuk 1
Then I try to unlock bootloader and root my device and get successful in this process and try some custom ROM's to make my handset with more interesting features ( thanx for the those developers who develop such ROM's , hat's to you guys) but after some weeks I try CM 14.1 , I messup with that process and got bricked device then I try to reflash that ROM , I have completed all processes very patiently , again and again I was ported to recovery ,not able to access my device. I became fed up with this then I leave my phone on customer care , after some days I get my zuk 1 with stock firmware
Now the main problem arises
Again I try to unlock my device
I have already install the adb and fastboot drivers and that working fine
I tried , adb devices
Its working
Then I try ,adb reboot bootloader
Its also working
But when I try , the script for unlocking bootloader
I get , { waiting for device }
Idk what's this happening
Lenovo USB drivers are property installed on my PC
Adb and fastboot drivers are also installed properly but I don't know ,what i am doing wrong
I think customer care ppls forcefully locked my bootloader that I can't able to root my handset in future
If anyone here to solve this issue ,ASAP

Hy bro.
I m having same problems two days ago.
I found the solution which issuccessfully working for me. First : downloade the universal necked driver (google it mostly found on google nexus 5 thread).
Second : change ur phone's battery. Get a new battery.
Third : remove ur batterry. Reinsert ur battery. Press volume down & connect USB cable u see the fastboot mode release volume down. Then go to device manager in ur computer and search unknown driver. Right click on it and select update driver update it manually ( google it how to manually update driver) browse the necked driver & select winusnb.inf then select Asus fastboot interface ur device got connect. Now flash official stock cm11 firmware through ygdp tool. That's it. Sorry for my bad English.

Fastboot can't detect my coolpad cool 1 dual. Please help.

I am facing an issue. I want to flash twrp into my coolpad cool 1 dual but my fastboot can't detect my device. ADB is able to detect it but as soon as I run the command "adb reboot bootloader" to boot my phone into fastboot mode fastboot doesn't detect my device any more.. I have tried updating the "android bootloader interface", " android adb interface" drivers but still nothing does work.. Tried a various types of usb driver available at xda in various threads but none work. What to do now? Please give me a solution to install twrp~

I got the same problem here, I installed a lot of several drivers and nothing. I keep surfing on the web trying to find a solution. If i get one I will notice you.

Same here.
Now i have no recovery, no system (ROM), and no EDL mode too.
Fastboot mode runs partially, with errors (REMOTE ERROR blablabla).
sad :crying:

I have already ripped apart the device. Took out the battery made an led emergency lamp out of it. The rest of it lies in some corner of my workshop!

Tried already bro nothing works i read somewhere that windows 10 have issues to unlock bootloader and everything works fine with windows 7.. But this thing doesn't make any sense according to me :/

Well, I am not an expert in this. It should just work. And the Windows 10 thing is absurd. I am using Windows 10. Plus, development mode is not enabled in my laptop.
Credits to the following -
@Sudeep Duhoon for this guide - [UNLOCK/RELOCK] Bootloader Unofficailly and Flash TWRP+Root
ASUS for phone, drivers, rom, this and that
Mod edit. Link removed. Reference: https://forum.xda-developers.com/one...rward-t3765018
@Saktis_STi for raw factory rom
@Shivam Kumar Jha for fixing the script
@Sujeet Ranipa for drivers link
@esashwin for testing

Use unlock.sh instead of unlock.cmd
If the phone is indeed detected in fastboot mode using
Code:
fastboot devices
, try running the script from unlock.sh instead of unlock.cmd.
I have not been unable to flash fastboot stock ROM from this laptop using the .bat file but for some reason, .sh file works fine.
Just install Git on windows. It will give you a wrapper to run shell scripts on your windows machine (Git BASH).
Again, I am not an expert. This might not work but at least it won't corrupt anything.

This happened to me as well, its problem with your pc(i mean drivers or just your os or maybe the usb ports, use 2.0 ports preferably) i have two pcs with windows 10 installed in both. One is updated and the other outdated. It failed in my updated pc, tried all methods like install, uninstall drivers, disabled driver signing, used different cables, used different usb ports 3.0, 2.0 but nothing worked. Atlast i gave it a try with my outdated windows 10 pc. It worked liked a charm. It has something to do with the drivers i suppose. Try in a different pc it might just work right for u as well

I had the same issue, after reading to many webpages, stumbled on this official unlock tool apk. Once the bootloader is unlocked using the app, the phone reboots into ASUS UNLOCK MODE with device status as unlocked and message to restart the phone. Heres the catch this is already the fastboot mode so flash TWRP at this stage. If you restart the phone in fastboot before flashing twrp, on running the flash cmd the screen of your phone would black out with a message "press any key to shutdown". Hope this helps.
unlock tool apk

then how do I install that official unlock tool in fastboot mode. since I can only access CSC FASTBOOT MODE.
