Bricked MP6900SP

My friend got a MP6900SP, and he tried to download a rom and flash it.
Now the phone is bricked, can't power on.
When connect to PC, nothing happened.
If I press power + volumn down + reset, PC will found a device.
No bootloader screen (tri-color), screen is totally blank.
RUU can't found the phone.
I did some research, but got confused.
Most post are for Verizon phone, not sure if they work the same for spring.
So, I am just checking to see if there's a way to revive my friend's phone.
Thanks all for the help!!

try to update via SD card
search for updating the bootloader via sd and also updating roms via SD
sounds like you may need to try updating the bootloader via SD first
good luck

Have you pulled the battery and let it sit for a minute then put the battery back in and tried to power on?
Blank screen and cant power on? sounds like something far more than bricked from the ROM he tried...
If you can get the screen I would try the suggested route with the flash from bootloader/SD card technique but if you cant get a screen at all no matter what and swapped out batteries as well (have seen a bad battery cause similar issues and may be a coincidence this is happening during a flash attempt)

To enter bootloader:
Power+Camera, then reset. No volume button.

Thank you!!
bootloader mode flash was successfully revived the phone.
Not sure what "power + volumn down + reset" mode is, but PC does show fine a data interface when I press them.
Anyway, thank you all for the help!!
You guys are good!!

i dont know how to put my mp6900sp in bootloader mode i tried the above still doesnt work only the start up screen and then it stays on

I don't know what the OP was saying about the volume button.
But just to be clear: if you are stuck at the bootup screen, having problems connecting and/or need to flash via SD card.....you want to quickly press and hold the top Power button + right side Camera button, then the bottom Reset button. The phone should display the rainbow screen and will say "Serial" on it until you plug the phone into your computer, when it should change to "USB".
For more help see this post and because I recommend an NFSFAN ROM this thread and this thread.

Pressing once does not turn it on. You need to hold it down for few seconds, til it vibrates. Then you can release it.

I do this but wont power on. I dont know why.
Its recognized on my computer as qualcomm usb or zeus flash device.

It's soft bricked, you need to recover your phone with Sony Update Service.

You won't need to power on your phone for this. Install Sony Update Service on your computer and follow the instructions given.

To turn off phone, take out battery (just to be sure)
Put battery back in.
Follow instruction from sony update service.
Press and hold back button first. Dont release
Now connect cable.
Should work now and update service will do its stuff.

Thank you guys but
It work, green led and updates loading, phone detected as s1boot download.
I unplug the phone and hold power button until vibrate but nothing
Now when I plug phone on the pc, the computer detect qhsusb_dload device
what is the problem ?

That is strange. I am running out of ideas to help.
Last idea is to use Flashtool and flash a stock GB/ICS rom.

I forgot if flashing by flashtool requires to have unlocked bootloader.

Ok thank You
I will unlock the bootloader and then flash the phone

[Q] Xperia Arc S Lt18 died after flash boot.img

Hey buddies,
I have a big issue:
My Xperia arc S is rooted, I did the bootloader unlock with sucess, and, when I flashed the boot.img (I had sucess by ADB), after ask to "fastboot reboot' my device died :/
It can't be recognized anywhere (USB-PC, wall charger, vol up + usb but it doesn't enter in fastboot mode), it doesn't turn on anymore.. When I hold "power button + vol up + vol down + camera button it's vibrate, but nothing happened in display. I had just this feedback.
Any ideas?
Thank you!

Try using flashtool. Hold down "menu" key and plug your phone into the usb. You will get into fastboot mode and then flash custom kernel.
After flashing kernel get into CWM recovery. Once you get in there its easy to install the ROM you want.
Make sure you flash kernel according to the ROM you selected or else you will get bootloop.
CHEERS!!

same issue

No, you don't need to press power button.
Switch off your device(which is already in your case) then while holding down the "menu" button on your phone, plug the phone into your computer via USB cable. If blue LED lights up, means you have successfully placed your phone in fastboot mode.
If its not working then probably your device battery is empty. You will need to charge it bro. And this might be a big problem unless you have got one more arc/arc s.

Sounds like the chargemon has been corupted of wiped! That could explain the charging issue. Try vol down & plug in usb for flash mode(green led if good) connect to pc companion and repair phone, or flashtool and the rom of your choice. If not it may be a jtag job im afraid n thats pricey!!!

This phone doesnt have any Volume +/- power button trick. It ONLY has the yellow reset button. Its a pain in the A*S!
Try a few things first.
1) When you hold down the yellow reset button, are you ONLY holding it down for a few seconds, and it vibrates ONCE?
Have you tried holding it down for 10 seconds, until it vibrates TWICE, indicating it has powered off completely, and THEN try connecting it?
2) If step 1 got your phone to power off completely try:
-Connecting your phone to your PC via USB with the volume DOWN button held and see if you get a GREEN L.E.D. If you do you have
successfully entered flash mode, in which case you can simply flash an FTF file with flashtool.
-Connecting your phone to your PC via USB with the volume UP button held and see if you get a BLUE L.E.D. If you do you have
successfully entered fastboot. From here, as long as you have ADB and your devices drivers installed on your computer, you can flash
a boot.img or "Kernel" with a fastboot command in a command window (fastboot flash boot boot.img). The easiest way to get a kernel or
boot.img with a baked in recovery is to download the latest Cyanogenmod, unzip and extract the boot.img, and flash it via fastboot.
Since you have an unlocked bootloader already, your device should be able to use an AOSP kernel.
From there you should be able to at least boot into recovery, and flash something from your SD card.
Id recommend just flashing the latest Cyanogenmod just to get your device up and running. From there you should be able to follow steps
get back to stock if thats what your looking for.
I hope at least one of these options work.
If not, like that last guy said, take it to a service center and get it checked out.
GOOOOD LUUUUCK!!

All ZL's are like that. Hold down till 1 vibration for reboot. Hold down till 3 vibrations for power off. The yellow reset button will not power on the device however. I figured I'd check just incase my power button decided to go for a sh*t.

[Q] Can't enter download mode

Hey guys.A while back I wanted to install adfree so I rooted my e975.Sometime in August I updated the android to 4.4.2 and I think the phone got unrooted.But SuperSU was still installed and I wanted it removed.So I tried a factory reset (settings->backup&reset->factory reset data) but SuperSU was still there afterwards.
Then I thought I should flash the kdz.So I tried to get my phone into download mode (volume buttons pressed and then connect to pc) but the screen shows nothing.I also tried going into recovery (volume down+power button) but that doesn't appear to work either.
Does anyone have any idea what's wrong with my phone?Everything else is working fine so maybe I'm doing something wrong.
Sorry if something doesn't make sense, English isn't my first language.

No one has any ideas?
I think this may be a hardware problem so I should find a way to hide the fact that the phone got rooted in case I need to sent it back.Is there any way to remove SuperSU without flashing the kdz?

Thanks for helping me brijen95.I just tried what you said and volume down+power key doesn't seem to work.The screen just stays black so I can't do a hard reset.Vol+ and connect to pc doesn't work either.The phone just starts charging after a few seconds.I also just reinstalled the drivers but it didn't change anything.

I had a hard time getting into download mode recently as well. What ended up working for me was holding the volume keys for about 10 seconds, then while still holding the buttons, plugging the usb cable into the phone.

No that didn't work either .
Is there any way to remove SuperSU?Keep in mind that my phone is not rooted anymore.
Edit: Well I just found out that the phone is entering download mode but not showing anything on the screen.I managed to flash the kdz with no issues.
