[Q] I brick my nexus, need help

Hello everyone.
Yesterday I tried to flash my nexus to f2fs. After that I wanted to go back to the stock, but forgot format filesystem to ext4 and run flash_all.bat.
Flashing was stopped on system write with error: "Unknown chunk type". After that i can't open recovery or turn on phone.
On 4pda i read, that bootloader reopen can help fix this problem.
When I flash new boot, nexus was died.
Can you help me?

Hi,
Please provide a link to exactly what you've flashed? Can you access the bootloader?

i flash google original rom
no, i haven't access to bootloader

you need to put your device in fastboot mode, keep retrying
then to go back to EXT4 :
- Flash back an official custom recovery (CWM or TWRP)
- Format Data from recovery
- Flash a kernel compatible with your ROM
- Reboot.

What happens when you hold down Power + Vol down keys together? Hold them until you feel a vibration. May be the battery has died? Keep it on charge for an hour and then try to enter bootloader?

nothing happens. When I put the phone on charge, it starts to warm up a bit in the camera, but even the display does not light up.
when i connect the phone to computer, it is defined as qhsusb_bulk or unknown usb device

Your memory is no longer accessible unfortunately, you most likely need to have it repaired (new motherboard) :crying:

If all the key combinations don't work, them your device is done for! Since it's totally dead there shouldn't be any problem to RMA it! Good Luck

Press and hold volume up while you connect usb cable to pc.
can you see download mode on device screen?
if yes read this thread entirely http://forum.xda-developers.com/showthread.php?t=2515760
Edit: try this also:
connect your phone to the pc, open device manager.
hold your power button until QHSUSB_BULK disappears, then in that split second press and hold both volume key while you still press the power key. it may end up into the second bootloader

thank you all!

[Q] Bricked : Flashing sbl1

I was trying to flash BlissPop. It didn't flash. So, I decided to flash fastboot image of CM11s 44.
I issued this command :
Code:
fastboot flash modem NON-HLOS.bin
fastboot reboot-bootloader
fastboot flash sbl1 sbl1.mbn
fastboot reboot-bootloader
The flash sbl1 command gave an error.
I rebooted bootloader. The phone turned off, but it never turned on.
I don't know how could it brick my phone, because I've done it a few times without any error.
My battery was on 65% when I was doing all this. So, I don't suspect battery has died.
But, I'm charging the phone anyway. There is no lead, but the power bank shows that battery is taking charge.
When I connect the phone to PC, it shows no signs of any device connected. Device manager doesn't show any thing/any refresh.
I've tried to push the power button for about a minute for 5 times, as 1+1 site says.
I've tried vol up + power and vol down + power buttons. It doesn't boot it.
I've no access to fastboot, recovery, OS, anything.
Please, suggest me solutions.

Did you flash the firmware updates before you flashed bliss? There is a toolkit out there, linked in bliss thread, on how to unbrick. I'll see if I can't find it.

First look at this perhaps. If not there is a toolkit out there to flash back to stock. Should be able to communicate w the phone if it can turn on at all.

Thanks. I looked at it.
But, as you said I can't do anything till the phone turns on even once.
BTW, I highly suspect battery drain, because I was in TWRP for long to take backup, flashing MultiROM, etc. TWRP is known to not allow charging, as reported by some people.
Can you tell me whether flashing sbl1 could have bricked it or not? It didn't fail to flash in past and it never caused problem.
I had flashed CM12 firmware update before flashing BlissPop. Could reflashing CM11s fastboot image over it cause problem. I think it should not, because fastboot image replace all things. What's your opinion?

Had the same problem. Try first leave it charging for 12 hours after that plug it in. Then get into fastboot this is not easy. Just hold vol up and power together for atv least 5 Sec.

I guess its possible. But I would do what falastine said. Charge it for some time. With a soft brick it may not show anything on the screen but could actually be on. So be patient trying to get the toolkit to find the phone. I've heard in another thread someone's phone did in fact connect but nothing was on the screen

any progress on this? i think the exact same thing happened to me. was trying to flash back to CM11s using fastboot, but it died. now i dont get anything at all. no response to the chrager, or the computer or anything.
ive tried holding the power button, holding the vol keys with the pwr button, but no avail.
let me know if you figured it out!

I left the phone in charge for 24 hours using original charger and wire.
Tried long presses for multiple times - nothing happens.
Tried vol up/ vol down combinations with power button for long nothing happens.
I am now waiting for 12 hours and then will plug it again, as some thread said.
In between I'm trying to download a tool from here : http://forum.xda-developers.com/oneplus-one/general/tool-oneplusrecovery-tool-v1-0-restore-t2991851
I hope it detects my phone.

There is no progress.
It appears that we are in same situation.
I highly suspect dead battery, instead of dead phone. Anyway, I'll post updates.
Please, share if anything works for you.

I had the same problem and had to restore the phone with this tool:

open your device manager in your pc and use volume up and power button while connected to pc to get into qualcom mode.most probably it would be detected as android fastboot interface just click on it and update the driver to qualcom usb serial interface then use http://forum.xda-developers.com/oneplus-one/general/tool-oneplusrecovery-tool-v1-0-restore-t2991851 this tool to recover

I could understand that once my phone is detected as even unknown device, I can install drivers and try to recover through the tool you mentioned.
But, the problem is that my phone is not recognized as anything. The Device Manager shows no reaction when I connect the phone to computer.
I have disabled driver signature on my Windows 8.1 64 bit. I've Qualacom drivers installed. Rebooted computer in disabled signature mode.
I've connected my device through official cable and I've tried the key combination mentioned.
My other devices show up when connected to PC, but 1+1 doesn't.
Any other thing which I could try.
I had left my phone in charging for 24 hours, but it doesn't wake it up.
Any suggestion is appreciated.

So this is how i did it.
1. install the drivers from OPO (located in the .zip file from this tool https://forums.oneplus.net/threads/t...ks-etc.237827/ )
2. Open your device manager (Start - right click on computer - properties - devices manager)
3. Press on power + vol up for like 10 sec until you see a device showing up (called QHSUSB_BULK)
4. Download the qualcomdriver ( https://www.dropbox.com/s/vgujdut93m341qm/Qualcomm 2012.rar?dl=0 ). Right click on this devices and click on "Update Driver Software" -> "Browse my computer for driver software" -> locate the Qualcomm 2012\fre\Windows7 8 or vista folder depending on your setup. Update the driver.
5. Now the OPO tool should recognize your device. I turn off all my network connections so the usb device can't find other drivers. (in case windows overwrite the driver).

The hard part is that I could not get the phone detected by PC as anything.
I followed the same key combination which you mentioned. It doesn't help.
Can you tell me if battery is totally depleted, will it be possible for phone to be detected?
I've tried to charge my phone with various chargers and power banks. The battery stays cold, the charger stays cold, power bank blinks and get depleted, but phone is not vibrating even on long press.
I've tried on virtual PC, a XP machine. And on other real XP PC.
Thanks for your help.
If you have some more suggestions based on information given by me, kindly post it again.

Even if your battery is depleted it should get detected in your machine when u press volume up and power while its connected to your pc.hold it for a minute this combination should show something also keep your pc volume up to hear any port connect discconect sounds.If this doesnt happen then your hardware is dead no other option but try to give it to opo for service.

So, nothing ever comes on the screen? Does the phone vibrate if you hold the power button for 20 seconds? If so, this might be of help, if it sounds like it's bricked: http://forum.xda-developers.com/oneplus-one/help/guide-unbrick-oneplus-one-t3013732

Problems with my d6633 Z3 Dual

Hallo people,
I have a very big problem with my d6633. I installed tonight TWRP - so fas, so good. After installing TWRP asked me to root the device, I said YES. My bootloader was unlocked. Then I couldn't exit TWRP. After every reboot the device started into TWRP. Now I can not start the device. I tried with Power+ Volume+, reset button - nothing.
Any suggestions?
Thanks for your help.

Sony Xperia Z3 Dual D6633
I have tried just about every method seen. My problem with the flashtool or PC companion is that the phone is recognized by the computer but I can only start to turn the device on which I don't believe it actually boots. Broken display and new display does not power on.
Or it connects in fastboot by holding volume up when connecting. This shows a blue led.
But trying to connect in flash mode by holding power down just makes the led flash red then green continuously.
And for the pc companion it always says the connection was unsuccessful once the led turns green on the device.
I got the phone for only $40 in this condition. So I cannot say what entirely was wrong or what it's last working state was.
I bought a new screen and power flex cable. As well as a back plate and tempered glass protectors. I was going to wait until everything works perfect speakers and all before I sealed it tight with water proof adhesive stickers.
Even before I bought the new power flex the computer recognized it and the battery health and charge %. The battery was able to charge. But I couldn't turn the device on.
The computer confirmed that it had been at 29% after some time charging and then 100% after leaving it on charge.
Now with the new screen and power cable the phone still does nothing if not plugged it. The light was red at first, but then yellow, then after some time green when the battery fully charged. This was again even before the new parts.
I have to plug it in to try anything.
It goes red then starts to turn on and turns green.
But I hear no sound, get no vibrations, the computer only sees it as the phone and shows absolutely nothing on the removable disk. Just blank when I click on the drive volume. But it is seen as an Xperia D6633 phone or fastboot Android device.
I've tried the reset button, holding power and volume up, volume down, all three. Tried my factory cable. Different cables, different ports, uninstalling it from service manager and letting the flash tool recognize and install it.
I also tried the new display on the old power flex and the old display on the new power flex.
Nothing changed, no vibrations, no sounds, system never actually fully starts as far as I can tell, and cannot connect in flash mode only fast boot. And the flashable file is only seen in flash mode. Fastboot can only see the folder but it is ready to flash files as far as I can tell.

@xdathekilljoy
That's a lot of money you're putting into an (apparently) broken phone Brave!
Okay so what happens if you hold Vol+ while it's shut down and then connect it to USB, the LED turns blue, right?
So why does flashing it from there on not work?

Well it didn't seem that broken at first and both it and the display were only about 37 piece. Power flex was almost 10. Seemed like a rightful price.
Yes the led turns blue and it is in fastboot mode. The flash file seems to only be readable for flashing in flash mode "volume down". I can see the folder of the flash file in fastboot mode " volume up ", but not in a flashable format.
And when connecting " volume down " it fails a connection while the led just flashes green to red to green to red continually

Two updates
1. I thought I should mention that when I do plug the phone in to a charger or computer the top does get a bit warm or hot as well as the led turns on. Different color depending.
2. With much fiddling and trying if holding the volume down button for different lengths of time while connecting up a computer I finally got it to connect in flash mode and flashed a file...... No change.
At this point maybe I should try a new battery for the hell of it even though this one seems to be working.
Or there is a minute hardware damage somewhere. Maybe the power ic? Or s capacitor?

Hard Bricked T-Mobile Z3, Doesn't turn on at all

I have T-Mobile Z3 (D6616) that I rooted and flashed TWRP on with no issues. Today I tried to flash ZyxxOS on it. after wiping and installing I went to reboot. The phone only powered off and then no matter what I do will not power on. I've tried all the button combos, LED's don't flash, I used the little yellow button by the sim, nothing.
If there is anything I can add let me know and I'll try to help to the best of my abilities.
thanks, Nathan
EDIT: If anyone can help me to the point that the phone boots or is completely fixed, I'll buy you a 6 pack of beer (or soda if you're too young to drink)
EDIT2: I let the phone charge all night and now (still plugged in) the notification LED is glowing red

Try to boot into Fastboot mode by holding the volume up then plug in the usb into your phone, if it detects then use the sony tool to reflash your firmware and it should work. If fastboot doesnt detect then I don't know what else to say.

So I left the phone on the (wall) charger all night and when I woke up the notification light was red. I hit volume down +power and the phone vibrated 3 times but nothing else happened. After that I tried connecting it to flash tool with a rubberband on the volume up botton. Flashtool's notification screen thing kept repeating "phone connected adb disabled" and then "device disconnected". I let it do that for about an hour before I took it off and put it back on the charger.
Should I still try and reset it by holding it for a few minutes? I read the softbrick thread linked above but i'm not sure what I should do or where my situation fits into that thread.
thanks, Nathan

Try this, open up flashtool and select your firmware, then click on the flash icon, after you clicked flash hold the volume down while connecting the usb cable and see if it the led changes from red to green/blue. Also what version of flashtool are you using? Maybe thats why its not detecting via the rubberband method. Also give this a go as well:
Recovery Mode:
Turn off the device
Press and hold Volume UP + Volume Down Key
then Press and hold Power key while pressing these keys
then press Camera key to enter Android System Recovery
Release all key when you see Android icon

im using version 0.9.19.8 but I am updating to 0.9.19.10 right now to see if that changes anything. Also how do I know if it's off? the phone doesn't do anything when i hit the power button.

If you plug in your charging cable and a red led is on that means it is powered off. So just try the button combination I have mentioned and hope it boots into stock recovery to try a factory reset.

I did the rubber band trick with the new flashtool, and the flashtool log just says,
device connected with USB debugging disabled
for 2011 devices line, make sure you are not in MTP mode
device disconnected
I get this over and over and it has been like this pretty much all day.
*EDIT: i held down power and volume down for a really long time this time and the led blinks red 3 times while I hold the buttons down.*

Darn, not much you can do since USB Debugging is disabled. Also is PC companion running the same time as Flashtool? That can conflict with it. If they are both running make sure to close PC companion and give it another go. Three red blinks means the battery is drained completely, but you said you charged it overnight. hmmmmm.....
EDIT: Leave it charging using original cable + wall charger for 10-30 minutes, after that unplug from wall charger with cable still intact then hold volume up and plug to PC and hope you see the Flashmode LED.

So I tried that and just got the same thing as before, with the "device connected with USB Debugging disabled." is there anything we can do to try and re-enable usb debugging in the phones current state?

Try these methods, if still no luck your last option is to send it in for repair

Dead 955F (dualboot)

so, i flashed lineage in dualboot on oreo firmware and my phone went completely dead, no download no vibration no response to anything i do to it. i just wanted to ask this question here too, is there any way this device could be brought back to life?

Try hold on volume up and down and power button at the same time for 30 second I think its kernel panic.

Also leave phone charging for a few hours and don't touch it see if it also was a bit low battery.

none of it works, left it overnight and tried every button combo

Power + Volume Down for 10-15 second simulates a battery removal, so try that.

Given it's not responding to that, and no lights when plugged into power, I'd say it's probably hard bricked and unrecovaerable. That's the risk when playing with things like dual boot etc I guess. Or just bad luck.
