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.

[Q] Unbelievable Galaxy Nexus problem.

This is my first post on the XDA forum. I registered only 2 try 2 have a reply 2 a problem that in my language (italian) is impossible to find out.
This is the best place for everything concerning android world so I hope to be lucky.
This morning my galaxy nexus, while I was playing @ paradise island, freezed and started to play several times a sound that was like an emergency (almost like the overheat processor beep in the computer cases - never heard that before). After this emergency beep the phone shutted off.
When I turned it on the Google logo appears but it start having gliches and reboot. This infinite times until the battery is removed. Sometimes it arrives to the colorful background but that times also it freeze (without gliches) and reboot.
Tryin 2 find out the problem I had a soft reset (battery off for 10 mins) but nothing.
I tried also an hard reset. The phone anyway after having selected RECOVERY MODE from the apposite menu start the google logo and when reaches the "red alert signal droid" the droid is gliched and the phone freeze and reboot. And start another time infinite reboots.
Someone know what kind of problem the phone have? It enters without problems in odin mode and the (I kind is called) bootload mode but don't start the recovery mode. I'm totally n00b, the phone is in fact stock, and I don't want 2 wait 1 month of assistance time if is a problem that can be resolved also @ home.
Please help me if you can and thanks for gifting me with your time.

Sorry to ask but I don't understand gliched, can you get in Stock Recovery (the "red alert signal droid" as you call it), push volume up and power at the same time and enter the recovery menu? Or not?

no I can't. The droid is gliched so the volume up + power combo doesn't work. The phone reboot some times. Some others times (like the trying I had now) the phone freezes.

Try flash the google stock images through fastboot, there are threads with instructions and links to everything you will need.
You should be able to fix whatever is wrong.

If doing it I can loose warranty?

No, you can re-lock your bootloader when you are done.

It MAY solve your problems, if they are software related.
If its a hardware problem it won't.
Give it a try anyway.

He is better off using fastboot and learning something.
Tool kits are the wrong way to do things, it is better to know what is actually happening when you pick an option in a toolkit.

the problem is that I don't know anything of this stuff. I don't know how to start.
The toolkit guide is huge and I think i should do only 2 or 3 of the all listed operation...
For now i took only the kit, the pdanet for win 64 and the yakju 4.0.4 from the google page. I don't know how 2 put them on and in which order.

.....

Oh, phone of my colleague has the same issue. We don't know what to do cause we can't connect Nexus to computer. When trying to do this Fastboot 2147483647 error occurs. Adb devices gives empty list.

Sounds like a hardware problem to me

Not sure if this is different on other phones but for me to get to recovery its not Volume up + Power. Its Volume up + volume down + power (i.e. hold both volume buttons then hold power button until it vibrates or the google logo shows up)

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.

Probably true that motherboard is dead, but I was mostly wondering if you did anything to the phone that caused it to do that. There is a hard-brick fix in the forum... https://forum.xda-developers.com/showthread.php?p=71495218

I'm so stupid...
so i have the same problem...but i don't think the motherboard is dead for only one flash zip...
I have installed magisk on my Xperia Z1 Compact and i bricked my phone. I was in a hurry and i didn't read properly how to installed it. The requiments wasto have an unlocked bootloader and i have lockedbootloader....
Now my phone didn't start. After i flashed magisk from TWRP and i received a message that i have to install SuperUsr and i choose "no". After that my phone doesn't boot up anymore since yestarday.
I tried to power up with simultaneously pressing volume up and power button and is not vibrating. All i have is a red light when i press power button. First time when i pressed power button it has vibrated one time.
I have put the phone to a charger and the light is red and pulsing and the charger isn't warming.
In flashtool i get that the phone is disconnected and in fastboot mode i can't get in, when i pressed volume up and then i put the usb cable all i get is a red light not blue...
Should i unlock the bootloader? But how, because i can get neither in fastmode or bootloader mode...
If you guys know a solution to boot up my phone i will be so happy.
Thanks!

I went to a local mobile repairing shop and the guy told me to replace the battery as the circuit of the battery was not working. So I did and now my z1c is back to life and working fine.
Hope this help someone in future.
Thank you

Hey ejay_gl, did you check the video that I have posted at the top?
The way you have described your problem I think you have hard bricked your mobile because I have faced the same a month before for flashing a kernel meant for unlocked bootloader in a locked bootloader device.
Luckily I recovered from that problem within 1-2 days.
Solution is little bit complex but I think you can do that with the help of google and YouTube.
Good luck.

Yes. I went to a local service shop and the guy over there manage to get my phone working. I'm so happy that i didn't have to buy a new motherboard.
But damn now i have another problem. i have rooted with kingroot but i can't replace kingroot with supersu.
I can't do this steps:
Open the Terminal app in your mobile , enter the command " su " ( without quotes ) . Allow Root Access in your mobile.
5. Now run the command - " sh /sdcard/mrw/root.sh " ( without quotes )
6. The SuperSu app will launch automatically , it will ask to update binary , click on CONTINUE , then Select NORMAL method. After the Binary is installed it will ask to reboot your device.
Is there another way to get supersu or a recovery. If I can get a recovery i will flash a pre-rooted firmware.

Question Pixel 6 Pro won't boot / Pixel Rom recovery

Hello hello,
Someone on another website told me to visit you guys here!
My Problem is as follows:
So around 6 hours ago my Pixel 6 pro decided to just turn itself off. I tried various methods of starting it, pressing different button combinations etc but it is completely unresponsive. I tried charging it for several hours but that also didn't do anything. The screen won't turn on at all.
The only sign of life that I have is when connecting my phone to my PC via USB and pressing all 3 buttons (Power, Volume up and down) then a device called "Pixel Rom Recovery" will pop up for a little bit. It disappears when letting go of the power button or after around 20 seconds. If I keep pressing the buttons it will apear again and do the same thing.
What I basically wanna know is:
Is there a way to still recover my data?
Is there a way for me to save my device?
I got some more or less important stuff on my phone and it would be a shame if it all was gone.
How ****ed am I?
Thank y'all for all your help!

Hi,
If you cannot turn on your phone, it'll be difficult to help you. Pressing other 30 sec power button doesn't run ?
In parallel did you contact the Google pixel support ?
It's not to scare you, but I had the same issue on a old Samsung S8 and it was the motherboard 🫤
Hope it's not the case for you !!

So this is in fact just an undocumented Emergency Download Mode that Google Custom Exynos SoC has natively built into it in case of the rare event of a bad boot loader.
I’ve been doing an extreme amount of research lately about bootROM’s, how they communicate, the Driver rule support for interfacing with the phone while it’s Pixel ROM Recovery. The viewable name for the Exynos USB DownLoading mode.
Can I get you to dm me on Telegram? It might be helpful to have more people. I’ll be glad to help in getting this figured out. It could help a lot of other people who don’t have a Pixel 6 too

I have the same issue after trying to update to 1205. I see the Pixel ROM Recovery and a COM port.

If you cannot enter fastboot mode, no way to recover your phone.

Was there a solution to this? The same thing happened to me. When I get to the bootloader and hit recovery the screen just goes black.
