[Q] Bootloader Bricked - Sony Xperia M2

My phone is Sony Xperia M2 (Single Sim) D303
I'm on android 4.4.2 and booted Doomlord kernel which was for android 4.3 So my phone got stuck in a loop. After factory reset(hoping it would work ) i can't enter fastboot mode. hoping for advice on how to enter fastboot mode and on someone with Sony Xperia M2 kernel so i can restore boot the stock kernel. Or on some other advice to help me get my phone working again. Right now im getting "device unauthorized" and can't even enter adb commands.
Flash tool doesn't recognise phone. It'd be helpful if someone even knows how to shut down the phone.
I got CWM recovery. So no longer got CWM but can now get into fastboot. Still no ADB and im stuck on Sony image.
Please help me.Thanks in advance.

Have you tried what I suggested in this thread?

My phone is a black screen right now. Can't shut it down,reboot, use adb commands, fastboot or anything. I'm worried if the power reaches 0% it could not even start up again. I'll try it tough, but really looking for diffrent options right now. I would try and flash it but i need to turn phone on and off for flash. I currently can't even do that. Phone doesn't start in flash mode. Maybe i should give it to someone for repairs but it'd probably cost me well over 200$.

I also need some MTP (i think thats it) drivers... Kinda strange don't know what im doing but sometimes i got the drivers and sometimes i don't

flashtool has all drivers needed from what I know. If you want to access phone data, MTP is the protocol used, and that should work out of the box.
Also, to flash the ftf you can use flashmode, so even if fastboot doesn't work, maybe flashmode will.
How do you know the phone is on btw? The only thing I to fix it is to flash ftf in flashmode, but you could wait if someone else has another idea.

The phone has a red light on and the screen is lighted black. I tried flashmode but i need to turn phone on and off for it to enter flashmode... I can't do that becouse buttons don't work for some reason. And i had all the drivers but since factory reset i lost them all (don't know how it works) well i got em all back without the MTP and can't install it with flashtool tried already. Also can't enter adb commands. It's like the phone is stuck on end of a loop. It's not looping the logo it's just stuck on the black screen after the logo and doesn't budge like an Iron Brick.

Answer
if you have kernel with CWM you can download flashable zip with rom and just copy zip to sdcard a then flash it in CWM.

Maybe you can try this,
1. Turn Power button and Vol Up, until first vibrate, keep hold it, and you will feel three times vibration. Now your device is off.
2. Open Flashtool, enter flash mode (push Vol Down and connect your device), reflash your ftf (if you are using DoomLord kernel that supposed to be 4.4.2 ftf), after flash is done, disconnect the cable and redo #1 (above).
3. Push Vol Up and connect your device to enter fastboot mode.
4. After that, go flash DoomLord Boot Kernel. When finished, disconnect your cable, but do not turn on your device yet.
5. Turn on and repeatedly push Vol Down to enter Recovery, go to install from sd card, and install SuperSU-Update.zip file (you must already have SuperSu-update.cip in your external sd)
6. After install supersu, you should go to advanced and choose power off instead of reboot it.
7. Do #2 again, but this time, when choosing the ftf, keep in mind that only kernel and loader to be flash (untick only for Cache, Data and Kernel). And do flash.
8. Turn on your device, and now your 4.4.2 is rooted.

does this work cause my xperia m2 dual is bricked after the logo it just turns blank

Is my Xoom bricked?

Hey All,
I know there are a lot threads like this on here, so I made sure I tried everything possible before asking for help.
First off, It is a MZ604 wifi version.
Ok, upon powering up my Xoom, it will get to the Motorola screen/ dual core and stall.
I am able to get into recovery, however the version I am running, 5.8.3.1 apparently does not allow sd card mounting, so I am unable to restore or flash a new rom.
A factory reset/ data wipe does nothing.
I have tried to flash a new rom via ADB, however my computer will not install the Xoom drivers. It will say "installing device drivers" for about 2 minutes or so before failing. I have tried using moto helper and the other Motorola usb drivers
I am unable to boot into android to enable usb debugging
I have tried all of the above on my laptop too and to the same result.
My question is, is this a brick? or can it be solved.
Thanks for your time
Yes it can be fixed, if you can access recovery then it means you can access fastboot. So what you do is once you're in the fastboot protocol, is flash in TWRP recovery http://forum.xda-developers.com/showthread.php?t=1782235
With that recovery you can mount SD cards, so use a computer to download the ROM you want then flash. Hopefully you get the idea, but I can post in more detail if you want.

Thanks for responding, I appreciate it. The thing is that my xoom cannot connect to my computer, and therefore and cannot use fastboot to send it the image correct?
I could fix all of this if I could just get the drivers to install, but because of my xoom's condition, the drivers cannot install no matter what.
Hmm usually fastboot drivers should automatically install. Does your recovery have an option to boot into fastboot? Once you're in fastboot it should automatically install the drivers, and in the android sdk folder in CMD (assuming you're running windows) put in this command: fastboot devices
It should show up your XOOM if not install this http://www.motorola.com/Support/AU-EN/Support-Homepage/Software-and-Drivers/USB-PC-Charging-Drivers
And try again
Hi all!
I got the same problem...
I can connect it to PC and do fastboot, I've flashed it many times, but it didn't affect my Xoom, i've reflashed the recovery to a lower version (tiamat rc4) but the recovery still shows version 5.8.3.1...
I even tried RSD, but it still the same...
no errors, and no effects...
is my Xoom bricked?
^I heard of this before, sounds like your new recovery image just gets overwritten by the current recovery. Though I thought it was only for stock recovery.
but, how can I overwrite it? it seems like they are read only...
It's all about timing, to access recovery once you see the Moto logo wait 2-3 seconds then vol + then vol + again. This is right after you flashed in your new recovery.
You can also access your fastboot like that as well, instead of pressing vol + again, press vol - then vol +.

that's not the problem... of course I can access the recovery, fastboot and RSD, the problem is that I whatever I do to the xoom just don't work... and it reports no error at all... it's just succeed, but nothing happened... It's like a PC running windows with DeepFreeze installed...
Anyone got the same problem? can anybody help me?:crying:
No you're missing the whole point, after you flashed your new recovery it may get overwritten if you don't reboot into recovery straight way. It never happened to me but I have read that people has that issue.

Restoring stock ROM

Apologies for dumb questions but I am really newbie with Sony phones (I know my way around HTCs though).
I have the Xperia Z3 Dual (D6633). After some reading, I've managed to unlock bootloader, installed TWRP recovery and rooted the phone.
My wife somehow locked the phone without memorizing password and the brightest idea I've had was to perform factory reset. Accidentally, I have managed to perform a full wipe, wiping everything except mSD card (I have experience with CWM recoveries but not with TWRP). I did not backup software before accidental wipe.
Phone obviously wont boot but I am having hard time to get to recovery as well, phone just hangs with TWRP recovery logo on the screen.
The first step I intend to perform is to try to re-flash recovery again a go from there.
My intention is to restore stock ROM using Flashtool and d6633_23.0.f.1.74_1288-7362_r8b_ru.ftf
I've read how to enter appropriate boot mode, however, I am not sure witch one to choose for Flashtool to work. BTW, is it possible to restore stock software using Sony PC Companion software?
Can anyone point me in a right direction? A simple guide to follow to in order to get out of this tough situation?
Download your desired firmware and install latest flash tool on your computer.
Copy the downloaded firmware on to the flash tool folder which can be found on your C drive.
Hold volume up and power together till your phone vibrates thrice (power shut down)
Now open flash tool, select flash mode and then your firmware. Now press start.. You will see animation there asking you to connect your device.
Hold your phone's "down volume button" and connect it to the computer. Flash tool will recognize the device and starts flashing. Wait for it to finish.
Boot your device and you are good to go!

Success! Thank you for your hand holding.
Order of steps to get the phone to flash mode was slightly different in my case though. When I pressed volume up and power key the device did not react. Repeating the same process with USB cable inserted worked. When pressing volume down the phone was tying to get to recovery but then it hanged there. In the end when Flashtool asked me to connect the phone, I've kept pressing volume down key with phone turned off and inserted USB cable and it got recognized and software got flashed in the end. BTW, Flashtool does't contain drivers for Z3 yet, therefore I've installed drivers for Z1 / Z2 in addition to flashmode and fastboot drivers.
Currently I am updating software trough Sony Update and then I will check if bootloader is still unlocked ant will try to get to recovery. If no luck I will reflash recovery.
Thank you again!
P.S. I've noticed that there are slightly different application included in this ROM. FTF file in these forums is a slightly different version that came with my phone originally. It might be useful to get more versions of FTFs for D6633 model uploaded...

The recovery you're booting to is not a custom recovery ,anyway I'll giude to installing I'll give some useful links.
First if all you need to unlock your bootloader go here

You may run in a bootloop (the phone stuck at bootanimation)
Just flash the stock ftf via flashtool .
Now go here and take the first method , it will guide how to install CM12

YU Yureka with no OS stuck on a Bootloop and unable to enter recovery mode.

Hey guys!
So, i was trying to install CM13 unofficial version, and wiped the system and internal storage using TWRP recovery. I was supposed to install the rom from a zip file i had placed in the external memory card. What i did, was, i rebooted the phone by mistake, after wiping it from the recovery without installing the ROM and now the phone is caught in a bootloop. I know i am an idiot to do that. I tried removing the battery and reboot it in recovery mode using the key combination with no luck. It just starts the boot loop. I tried using fastboot and adb from pc to push files into the internal memory, but my device is not getting detected on the adb anymore (maybe the usb debugging is disabled now?).
What i guess is stopping TWRP recovery from showing up is the lack of twrp/themes folder in the internal memory since i wiped it. But there might be some other cause that i am unaware of. What do i do now? Any help will be greatly appreciated!
Hey! I'm having the same problem with my yu yureka.. Can anyone help me please!

Hi! I'm having the same problem with this post... Does anyone knows the solution of this problem. I'd be really glad if anyone could help me with this..please!
Hey are you able to boot into fastboot mode? If you can....
Prerequisites –
1. Make sure that you have 70-80% battery on your phone.
2. You need a PC and a USB cable to connect your phone to the PC.
3. Flashing the factory firmware will wipe all the data present in the internal memory. So, make a backup of that if you can.
4.Install all the necessary Device drivers.
DOWNLOADS -
1. Download the flash tools from here . http://www.mediafire.com/download/87gfz7mdch188an/Flashtools_For_Yu_Yureka.zip
2. Download the factory firmware from Here (cm 12.1) . http://builds.cyngn.com/factory/tomato/cm-12.1-YOG4PAS3JM-tomato-signed-fastboot.zip
Steps To Flash Factory Firmware –
1. Extract the flashtools zip in a new folder on the desktop.
2. Extract the factory firmware zip in the same folder and make sure that all of the flashtools files are also present.
3. Now, power off your phone. If you are stuck in a bootloop, then pull out the battery and reinsert it. (Do not switch on the phone.)
4. While pressing the Volume Up key, connect your phone to the PC with the help of a USB cable.
5. You should now see the fastboot logo on your device. If you did, leave the Volume Up key. (If you do not see the logo, retry the process.)
6. Now go to the folder where you extracted the flash tools and factory firmware and run the flash-all.bat by double clicking on it.
7. A command window will open and the flashing procedure will start. (Make sure that your device does not disconnect from your PC during the procedure.)
8. The command window will automatically close once the procedure is completed.
9. Disconnect your device and boot it up by pressing the Power button. (Since this is first boot after flashing the firmware, it may take upto 5 minutes.)
Done you should be back on cm 12.1

I am also facing problem maybe worst
I dont know what wrong I am doing but I am getting "FAILED (remote: unknown command)".

3. I have red light on, phones keeps rebooting 4-5 times than red light goes off and charging stops.

Ignore that and use other fastboot commands and go ahead, as your device is being detected in fastboot mode.

But when I am executing other fastboot commands it halts the process between with error "FAILED (remote: unknown command)".
I have read about this error and people suggested that I need to get into "Download mode" not "fastboot/bootload". To get into "download" mode I tried pressing "VoulumeDown+Power+Home", but nothing happened, it simply restarted the phone.
Please advise.

bootloader disabled

Hi all, recently i've flashed Nitrogen rom with kernel, but i was flashed the wrong kernel. 2202, mine is 2203. The phone is rebooted but no screen just it's screen on. After reflash the right kernel, 2203, everything got to normal but my bootloader is missing. Can't access to him. I try everything, reboot mode in bootloader, vol - power. The phone boot but by pass the bootloader and goes directly to system. I tried resolving issue with Sony companion but an error when he told me to reboot with vol- power, it's booted directly to system after few second.
Someone can help me ? Please.
Thks
Try with Emma (Sony flashtool) insted of Sony companion or use Flashtool by androxyde (community flashtool) and flash .ftf file.
