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.

Booting to recovery with button combination not working

So, after trying out a few firmwares (JM2, JG8, JM5) and kernels (Samset&OC) I can't no longer boot to recovery with Vol UP + Home + power. I can't really say when this problem first occurred, but maybe with JG8 flash. The strange thing is that I can get to recovery with adb reboot recovery and through android console with reboot recovery (when rooted ofc). Also download mode works great.
Things I have tried:
-flash again to JM2 and JM5 with re-partition checked (512 PIT)
-cleared cache+data through recovery
-factory reset through phone code (this also cleared the internal SD)
-took out the battery multiple times
-booted phone without sim
-flashed phone without sim
-changed CSC with phone code
-restore a nandroid backup of JM2. Recovery worked with this one when I took the backup
-there's no external flash card inserted
Soooo..does anyone have any idea about this kind of problem?

i had a similar problem after trying few ROMs. In my case, when i pres the key combi i get the boot logo and then few seconds later the screen goes black and then i see the boot logo again, and this goes forever. and then i tried pressing the same key combination simultaneously and once i see the boot logo i let go the power button and keep the vol up and home pressed, and then only it went into the recovery mode.
hope it works the same for you
Cheers

Agreed, 99.9% chance you are doing it wrong.

mmthabet: I had the exact same experience. Letting go of the power button when the logo appears lets me enter recovery.

or you may need to take out the battery first for a few seconds... after that, you can reinsert it back and try recovery mode...
at least this work for me...

Thanks for replies but none of the solutions work. The recovery mode button combination DID work for a few weeks, but then just stopped working.
I know that I'm doing it right. I have always pressed vol up and home down until the phone loaded recovery and only briefly pressed power button just at the start. I have also tried to remove battery multiple times and once waited 30 mins before re-inserting it.
Trust me, I'm not doing it wrong :s And recovery is working great through adb reboot recovery and shell.

More so a timing issue. Buttons not pressed at the same time.
I get it all the time for all combo's.
Just keep trying.

You might already have this however just in case you dont, check out Quick Boot.
http://www.appbrain.com/app/com.siriusapplications.quickboot
With this app you can boot into recovery mode. Have to be rooted though.

this wont work, if you bricked the phone in a bad flash situation.
in times when this app works, you can easily do adb reboot recover
so this app still doesn't address the real issue of how to get the 3 buttons press hardware recovery mode

I release the buttons right when the first Samsung texts comes on the screen. It will take it to Recovery mode. I also had a "boot loop" few times, if I keep pressing the buttons all the time.
Have you tried release your fingers right in the first texts? I really don`t know what is exactly the right way to press the buttons, but this always have took it to Recovery.

Looks like my latest full wipe with *2767*3855# cured it. Flashed JM5-->full wipe-->samset1.9b-->samset kernel and now it works. It must've got stuck somehow in my previous JM5 installation.

I cant get into the download- or recovery-mode by using these keys... so i am not able to flash a new firmware! can anybody help me please? is there a chance to get into the download mode by using an adb-command?

yes
adb reboot download
but it is dangerous, as you can not recover from a bricked state, if your flash is not compatible or if something went wrong with odin, etc.

I you're bricked and can't get into Download or recovery mode, leave the device to boot, it will just show a black screen for a while then will turn its self off, once this happens you should be able to use the key combo.

I usually release the power button on the boot screen first and then the other two buttons

Any idea how long you waited? Been waiting 5 minutes, hasn't shut off. Mine's a Bell though so I'm guessing I won't have any luck.

The way i do it (no chance of doing it wrong and timing):
hold down+home and then also press the power button for a little more then 10 seconds (so all 3 buttons for 10 seconds). The phone will reset into download mode, never fails in whatever mode the phone originaly was..

Xperia Pro MK16 Power on one time only

Hi everybody

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.

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.
Use this thread for all instructions and download links - http://forum.xda-developers.com/showthread.php?t=1642480
I forgot if flashing by flashtool requires to have unlocked bootloader.

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

You might have to factory reset in recovery (vol up + home + power). I read you removed the power button, that's so not useful lol.
Maybe you'll be able to use ADB to boot in recovery or a jig to boot in download mode (if it gets to that point).

no luck

Hold all 3 buttons until he boots up (vibrate), then release the power, while still holding home+vol up. It should boot in recovery.

Depending on your carrier, you may be able to flash a stock ROM via Odin.
If you have the 4.3 bootloader, only flash a stock 4.3 ROM. If you have a 4.1.1 or 4.1.2 bootloader, you can flash either a stock 4.1.1 or 4.1.2 ROM via Odin.

NOOB: hard bricked op3, volume up button hasn't been working

First off, I did do a search, but as far as I can tell no one has had this problem so far.
This is all after modding using a tool kit: (i can't include the url but it is the toolkit by neisor on the oneplus forums)
tldr: phone stuck in bootloop, computer wont recognize the phone, maybe because it keeps shutting off and then booting to the 1+ logo, then shutting off again, would drivers help? what can I do about the volume up button?
So for a while my volume up button hasn't been working, and the mega unbrick post shows that I need to hold the volume up button for at least 25 seconds and while holding, plug my phone in. I have also seen some posts that say the volume up button could be a software issue, and the button itself could be working, and it is just not registering, as well as someone saying that you could take the back off and manually press the button, instead of using the bar on the outside of the phone (would this work?). I have gotten the button to work in the past by pressing the volume up button to the side instead of straight in, but I haven't been able to get it to work since my phone got bricked.
Another issue: my phone is stuck in a boot loop, I can't access fastboot, and I'm unsure of recovery because my volume up button is not working. would it be worth it to deal with the constant vibrating to try to get it to recovery?
I have been able to shut the phone off by holding the power button for something like a minute and a half, though.
This is my first post, and if I have broken any rules I am very sorry, but I need help and am tired of not having a phone.
Thank you everyone,
Mark
Edit: this is what I did to root the phone:
1. download the toolkit
2. unlock bootloader (when fastbooting the phone said unlocked at the bottom, and a message about not being secure showed every time I rebooted the phone)
3. flashed twrp (no issues, still booted, recovery went to twrp. for some reason I had to flash multiple times as every now and then recovery would revert to stock op, although I did make a backup through twrp)
4. send supersu zip file to phone, install using twrp (phone would not boot, op logo stayed on phone for 2 hrs + until I rebooted to fastboot and tried to reinstall the backup I made, still nothing)
5. Try magisk (still stuck on op logo)
6. try to go back to stock, accidentally lock bootloader (now the phone is stuck in bootloop, don't know what to do from here as I cant get to fastboot and am unsure of recovery's accessibility.)

If you are sure you have a broken volume button, you need to replace it first in order to get the phone fix.
Correction:
Fastboot/bootloader = Power+Vol Up
Recovery = Power+Vol Down

This happened to me except I didn't even get anything appear on the screen -- the phone just periodically vibrated with the screen not even light up. I tried the reset toolkit which is meant to flash your phone back to normal using Qualcomm drivers or something, but that didn't work either. Eventually I had to send it to OnePlus who fixed it for free in under a week! They said the motherboard had failed.
I hope you get this fixed!

Thanks

Damn, that sucks, and besides being unfixable (doubt it), this is my biggest fear. I'm in the US and really don't want to have to ship my phone to china to have it fixed. If you are in the US as well do you know if there is a OnePlus branch I can send it to in the US?

There seems to be one in Texas. Anyway, contact OnePlus and they may try to solve it over the air.
Apart from that, did you install the Qualcom drivers properly? Even with your faulty power button, try to hold it down for 40+ seconds (for the phone to switch off) and then immediately hold down the volume up button for 10 seconds and then plug in the phone to the PC. I know I am merely repeating the instructions of Naman Bhalla in his Mega Unbrick Guide but it is crucial to do them correctly especially the installation of the drivers. Try these steps repeatedly because for some people, the phone gets recognised after repeated attempts. Or else replace the power button and then try these steps.
I had to use the Guide last month and successfully resurrected my dead phone.

Can you boot into recovery by pressing power+volume down buttons?

Update: Got phone to show on computer as qualcomm under coms and ports
So last night I went ahead and held volume up for about 20 seconds, then plugged the phone in, keeping the volume up button pressed the entire time. my phone stopped bootlooping and showed up as a qualcom device! So I have downloaded the new driver the stock os, and am going to proceed to try to unbrick my phone.
Wish me luck,
Mark

Yes, I did, and its working so far

I still need to turn off the signed drivers features ( a huge bi*ch, I have to use another computer to contact microsoft or something to get my computer to load when I turn off safe boot or whatever its called), but once I do that I can install the driver and attempt to reinstall the stock os. Hopefully everything will go well.

So far recovery has not been loading, just the bootloop, but I have gotten the phone to power off by pressing the power button for 40 seconds, and the volume up button plus plugging in does make the phone register as qualcom 9008 or something like that. Basically everything is going well so far, and the faulty vol button seems to have been a software bug, as it does work when plugging it in. I will try to get to fast boot, but it did not work last time.
