Sony Z Ultra - C6883 Unable to get into fastboot mode - Sony Xperia Z Ultra

The phone has been in the drawer for quite a long time (5+ Years)
I come to try flash root to it and it wont boot into fastboot. all that happens is a black screen and nothing else.
ADB reports it as being there till it reboots ( 'adb reboot bootloader' ) , when the phone reboots its a black screen and if i plug in a usb lead then i get the standard windows was unable to recognise this device. ( Attached is a device manager Grab of it )
I have tried to use Flashtool64 (latest version) it reboots to the same black screen. The only way then to get it back to a usable phone is to unplug the lead and press the power button till it vibrates.
I have spent 10+ hours reading and reading everywhere and nothing that has been suggested has been succesful.
This is my last hope ( I realise its a 10 year old phone) and am hoping someone can help me sort this out.
Many Thanks in advance

You wrote nothing about the version of adb and drivers you are using.

Tried that.i have spent a very long time on this. Starting to get to the point that the phone is poop. And needs to be binned

To confirm the functionality of the equipment.
Can you transfer files from/to phone in adb mode?

Yes, the device problem only happens when it reboots to bootloader for fastboot access. I think bootloader is corrupted . Can't flash new one without boitloader/fastboot access. Well that's my understanding

What about flashmode?
Flash mode:
1) Connect the USB cable to the computer (do not connect it to the phone yet)
2) Turn off the phone
3) When the phone turns off, plug the USB cable into the phone and hold the Volume Down button
4) The phone should boot into Flashmod mode!
Your Xperia Z Ultra should be in Flash Mode now and the device’s LED light should turn into Green
Fastboot mode:
1) Connect the USB cable to your computer (don't connect it to the phone yet)
2) Turn off the phone
3) When the phone turns off, plug the USB cable into the phone and hold the Volume Up button
4) The phone should boot into fastboot mod!
Your Xperia Z Ultra should be in Flash Mode now and the device’s LED light should turn into Blue

Same. Even EMMA doesn't work. Which was a suggestion. Or flash prog (used old and new) all seem to reboot to bootloader/fastboot which has same error as stated.

The usb vol down with plugging in usb / power on doesn't work either.
neither does the vol up + power / usb
ammended to clarify

when powering up/vol down i get a short vibration, then it boots normally. pressing vol up + power gets black screen.
usb + vol Down does nothing, usb + Vol up also does nothing

I am thinking that the phone is not booting into a software that 'tells the USB what it is. Th OS boots fine tho and it sees the phone and can xfer to and from the phone

1. Get into Download Mode (WITH THE PHONE PLUGGED IN) by following the steps below
*Turn off the phone until you get to the charging battery screen (keep in mind, your phone is currently PLUGGED IN)
*Press volume up and down, and power all at once.
*As soon as the screen turns black, release your power button.
2. Unplug phone from USB
3. Open Odin (in Administrator if you're running W7 or Vista), try one of the ones I attached to this post, at least one of them is bound to work, some don't work for me, but works for others, some doesn't work for others, but works for me, whatever floats your boat
4. Load in the files into Odin that you have downloaded from above Just load in the files corresponding to the text field.
DO NOT CHECK REPARTITION.
5. Plug in your phone with the DL mode
6. Click start and wait for the magic
i can get into recovery mode but not dl mode, an my pc never recognized my phone via usb even when android worked

Try my how-to...
Also, try pulling the battery, and then holding the Vol up+Vol dn keys, plug the usb cable in, then plug the battery back in..., make sure the usb cable is plugged into your computer...
Or.., if your phone is partially booting, then:
Code:
adb reboot download

i think i have a hardware locked phone, i just got it today.
But i can get into recovery mode via hardware, so maybe i dont have hardware locked? and it IS possible to get to download mode on my phone via the buttons right?

1. Turn off device
2. Remove battery
3. Hold Vol up and Vol down (works best upside down)
4. Insert battery into device
5. Plug USB cable into device (also plugged into your computer)

If you follow the steps your phone will enter download mode, In order for your PC to recognize what kind of device is plugged into it you need the samsung drivers. Which are here http://forum.xda-developers.com/showthread.php?t=728929

yes, so is that fixable?
Yeah definitely fixable, You just need to install the Samsung drivers onto your PC. Use Odin to flash a stock ROM onto your device and things should be better for you. I would suggest doing some research here on XDAand getting familiar with flashing a phone. Ive recovered from where you are now(a long time ago) this phone is very resilient. I have a thread over in the Q&A section with links to a video tutorial that I made for flashing a phone from stock, rooting, then all the way up to nero. Do a search on it, Good luck!
i just need to get into need to get into download mode and get odin to recongnize my phone and i should be good, it's such a pain! ;(. But THANKS for your help! I wish theres just ONE way to get into download mode.

Xperia Z Tablet Bricked

Hey,
I have a problem. My tablet is SGP312 has Cyanogenmod 11 (FXP247 - Android 4.4). It was bricked when I type in Terminal:
Code:
su
reboot recovery
Was turned off and will not turn on at all.
Power button = NOTHING
Power button + Vol(+) 3/10/25 secs = NOTHING
Power button + Vol(-) 3/10/25 secs = NOTHING
Power button + Voll(+) + USB = NOTHING
No LED light, It's literally a paperweight. I can't even put it into Flashmode.
Please help me!

Are you sure u can't put it in to flash mode, because that's the first thing I would do
Try putting it into fast boot mode
Hold volume up button and keep holding it and connect it to the pc
If you see blue light on your tablet, it means it has successfully entered fast boot mode
Make sure all the drivers are installed
Or
Follow the following procedures
Install Sony Ericsson flash tool and install all the drivers
Hold volume down button and keep holding it and connect it to pc
Once you hear the connecting sound our Any notification on your pc saying that it is connected, go ahead and flash the ftf file

in my opinion, the drivers are not correctly installed
http://developer.sonymobile.com/downloads/drivers/xperia-tablet-z-sgp311-sgp312-driver/
go to the website and download and load the drivers on your pc
its just weird that it says device connected with Usb debugging off when it is actually powered off
try charging your device, maybe the battery needs to be charged leave it there for atleast 30 mins then try the steps
let us know if you fixed it or not

I have a similar problem, I've flashed plenty of devices before, never briked a thing.
By unloking the bootloader the data partition of my brand new tablet Z went corrupted. I've tried to flash several firmware but none was succesfull (couldn't format data...), and finally it get totally bricked! no light, nothing... I was not even able to put it in flash mode (no light ever!).
I've tried after a while, I've read with some other Xperia devices, it would be possible to recover it after some time, by letting the battery die, then use some rubber trick to keep vol- pressed... you can find it in XDA forums what I'm talking about. However after a month my tablet was still dead. no light, no nothing!
I've sent it to warranty and the just said that "an alternative firmware was flashed" (voiding the warranty) "and has rendered the logic board unusable".... and they have to order a new unit!!
I feel so surprise that even the cheapest chinese tablet have an harware mode that allow to reflash and resuscitate it back to factory... even if the firmware is completely screwed, and a 600$ tablet for a simple bootloader unlock got totaly bricked.
I wonder if there is an "hardware" way to recover the tablet (I saw it's pretty easy to tear down the Xperia tablet Z), by directly accessing the NAND... or by accessing some PIN (well I know sony would have not leaked such information)

My Device isn't recognized by the pc and the fastboot or bootloader mode don't work

I know that this thread is more of same, but I didn't found any answer that helps me.
The story is:
My Xperia 2363 M4 Aqua Dual recived a call and I lost it. Then when I took it and turn on the screen to see the caller, my device just restarted and went to the purple waves screen, but stuck there the system didn't start. Since this, the only thing that phone do is that, it never starts the android system.
I've tried everything that I read
So the things I've tried is:
Restart the phone by holding the power + vol up buttons
Turn off the phone by holding the power + vol up buttons until 3 vibes
Turn on the phone holdin the vol up + vol down buttons
Reinstall software by xperia companion but the software didn't start the process
reinstall software by flashtool but the device isn't found by the flashtool
connect the phone on pc holding vol up button
connect the phone on pc holding vol down button
connect the phone on pc holding vol up + vol down buttons
connect the phone holding all the buttons
the fastboot and bootloader modes don't enter and the pc says that usb device can't recognized by the windows.
I have no ideas of what i do
Can you help me?

Thanks for reply. No, didn't flash a blue screen, it just restarted like when we hold the power +vol up buttons
And it not keep restartin, the phone turns on and stays on the waves screen. don't start the system so as don't restart.
If you device is not being recognized by you PC, Try fastbooting the device using a linux (Mint, what i used for similiar issue), it will hopefully recognize your device and you would be able to flash it.

Unfortunately no. I couldn't fix this yet, it is because I' can't go fastboot mode on my device
have you any other suggestion?
no i have that problem by the way if you can fix the prob. then contact me pls
The other phone you tried was a Xperia?
And are you on Win8 or Win10 because if you are, you have to install the drivers in unsafe mode(Don't remember how it's really called).
Furthermore if you don't have anything important in the phone try flashing a new version of Android or the same but do a clean install I.E Wipe everything and leave like new by installing with Flashtool(unsafe mode too, because it needs drivers if you are on Win8>10 when installing)

My phoned is dead and i dont know why!

So i was using RessurectionRemix (a version from last month) and recovery twrp 3.1.0-0 and the phone was working great!
Yesterday i left my phone charging over night and in the morning i wake up to my phone bootlooping!
So i tried different things including everything it says here https://forum.xda-developers.com/le-max-2/how-to/guide-hard-brick-fix-qualcomm-hs-usb-t3492949 without luck
I can get it into recovery and fastboot but as soon as i let the key combination go the phone stops and just shows a black screen (screen is on) and i cant get into qualcomm recovery to flash!
And the only way to shut off the phone is by holding power + vol up + vol down!
Any solution or suggestions?

connect phone to computer, try force shutdown phone by hard button, ater phone shutdown, immediately release power but keep both volume. Phone maybe will enter Qualcomm flash dead mode, and Flashone will regconize com phone (refresh nedded)
Hope you success ! And believe, if a phone can flash with Qfil or Flashone, almost that phone never die (software)
Are you able to connect to the phone via Vysor, either via Chrome browser or as a standalone app on Windows PC when you do not see anything on the phone screen? Please post if Vysor install goes thru successfully. Hope your developer options/USB debugging are on. I assume your phone boots but may have display issues either hw or sw.

Phone gets recognized but not long enough to do anything (windows makes sound but doesn't install anything and doesn't show up in device manager)
try this guide
https://www.gizmochina.com/2016/11/20/leeco-x820-max-2-super-unbrick-guide/
You have mentioned that you are able to see the device in recovery and fastboot till you release the buttons - does this mean if the buttons are held say in fastboot mode you are able to see the device via "fastboot devices" or in recovery the twrp screen or nothing ever shows up at all? Are the buttons clicking properly? Check individually to make sure - particularly the power button. Does it vibrate at any point of time when you press and hold the power button? Are you able to see any backlight when you say the screen is on?
If there no backlight shine a torch or sunlight from the side of the screen to see anything at all on the screen.
Vysor reports apk not installed when it attempts to download from PC to phone but fails. With Vysor you will have two windows one showing status of phone - this is the main window. The other is the mirrored one - that of the phone when you click view on the main window. I forgot that the phone requires approval to install the apk. Please see the attached thumbnails. Keep touching the screen about 3 cms up from the bottom of the screen (not the phone) to see any change. Hope your touch works.
I know it is quite frustrating to try a number of things. I recently went thru the same on Galaxy S4 to make sure the phone but for the screen works OK prior to ordering the screen. Besides in my case developer options was disabled and touch also did not work. It took about a week of learning and trying to see something on Vysor. I never have used a Sam phone till that time this broken phone was handed over to me.
After a lot of trying i found out that when i keep pressed power + vol down or vol up while connected to pc and device is off it gets recognized as
qualcomm hs-usb qdloader 9008 long as i keep the keys pressed so i tried the flashone method but it just says could not connect
Are Qualcomm drivers loaded on your computer? I have not used flashone. I used QPST to see if phone is connected. I am not sure if they are same.

It doesn't stay long enough in recovery or fastboot to do anything it shuts off after a few seconds even with the buttons pressed after that it just shows a black screen
Phone vibrates when i press power and shows leeco logo (not os logo) and after 1-2 seconds screen goes black and phone vibrates again and shows leeco logo again and just continues looping
if i try to press power + vol up normally it goes into recovery but as soon as recovery is loaded screen goes black (screen on just doesn't show anything) the same goes for fastboot if i press power + vol down it loads fastboot but after 1-2 seconds screen goes black
if i keep pressing keys the phone just stays longer in recovery/fastboot but only 4-5 seconds
I assume you have adb and fastboot. Since you say the screen remains on when booting to recovery open a command prompt at the directory where adb is and issue a command "adb devices" without quotes. Does it just exit without showing any device or throws up some error? Try this irrespective of the black screen.
Have you looked at and tried what is given by @HTC-TYTN2 at post #8? It is for Le Max 2 and you will find a link to Quallcomm drivers too. Do not bother that the link mentions X820 even your Max 2 is 821, 829, etc.
since it happened after charging, you might want to check your cable and battery. best is to get a cheap usb multimeter.
Gesendet von meinem LEX820 mit Tapatalk
I too thought it could be the battery based on that's the screen goes off. But he also mentioned that the screen remains on but nothing to be seen after a short while. Wanted to suggest slow speed charging probably via a laptop usb as I'm not sure if he used high speed charging resulting in battery issue.
Did you solve the problem?
My phone just died completely! No response at all anymore. I'm contacting the seller now to send the phone back.
Looks like it is a hardware defect! A pretty odd one but nothing i can do anymore. I send it back and post what the problem is as soon as get any information.
Thanks to everyone who tried to help!

Sony XZ1 G8431 bricked

Hello guys, i have sony xz1 g431, i bricked my phone when i try to install another rom of another device via twrp. Now my phone no light when connect to pc, no light when charging, flash tool doesnt recognize my phone. When i connect my phone to pc it only shows QUSB_BULK on my pc. I think it lost fastboot or something. I try hold down button, up button or both when connect to pc but still no light and nothing happen.
Please help me fix this problem or atleast some good suggestions to solve this problem. I will really happy for that. Thanks :crying:
Just have the phone powered off, hold just only the volume down button and while holding it, connect the phone to usb cable to your PC.
It should enter flash mode (green light), where you can flash stock firmware via newflasher (or possibly also via flashtool, but I do not use that).
If you have the phone off, hold volume up button while connecting to usb, it should enter fastboot (blue light), which also may be used for some recovery, if the phone has been unlocked (or for the unlock itself).
If any of those modes are available, the phone should be possible to recover.

i have tried it but there's no light. I think it's dead :crying:
@Karl Einstein, have you tried both ways as suggested above?
Maybe you can examine what usb device appear (if any) in each of the described modes (tried to enter flash mode, tried to enter fastboot mode, tried to just plug the phone to usb without holding any button from power off state).
What happens if you try to enter recovery mode (twrp) - having your phone powered off, without usb connection, holding volume down and power, should enter twrp if you had it flashed before.
Do you get any vibration when hold the power button and.volume.key.up?

Well...I think your phone is dead...I'm really sorry to say that, but in this case, that is the only reasonable explanation.
Yesterday I flashed the GSI image, then tried to flash to eXistenZ, it just stuck in the startup interface. However, it can still enter flash mode and fastboot mode, I have no choice but to use the newflasher to re-flash the firmware, it will return to normal.
In general, Sony devices are hard to change bricks, unless the phone is a Japanese carrier's custom phone (generally can not unlock the bootloader, and can only flash some firmware).
I have seen users who have flashed CE firmware for the docomo version and then can't enter flash mode and fastboot mode.Unlike your device,her phone is totally dead...It can't be charged, and there is no prompt to connect to the computer.
If you can buy a motherboard from eBay or somewhere else,you can disassemble your phone,then replace the old motherboard.
Hope these helps.
Thank you guys for all your support. Finally i decided to skip this problem and i will buy a new device

Just a side note , why flash existenz on a gsi rom... As it is made for stock Sony only or did I just misread something..
I had the same issue before on my lenovo p2 it lost fastboot and download mode but the PC detect it as qusb bulk then Qualcomm USB h9008 I searched all solutions but no good I think it needs some kind of box to push the modes or change the mother board. So I changed to Sony instead of repair it

Sad to ear that...
I had the same issue with my previous Htc10.
As it was still under warranty, I have had to contact HTC support and told them that and OTA bricked it.
They accepted the issue and replaced the motherboard.
I was BL unlocked, rooted and custom rom when it happened and no issue with support as they had no mean to prove it ?.
If still under warranty try to contact Sony support and tell them the same story... Ota bricks my phone ?

I've flashed eXistenZ before flash GSI in my phone. I thought GSI image would cover my origin ROM like eXistenZ, so after flash GSI image in,I flash eXistenZ again.

Just have the phone powered off, hold just only the volume down button and while holding it, connect the phone to usb cable to your PC.
It should enter flash mode (green light), where you can flash stock firmware via newflasher (or possibly also via flashtool, but I do not use that).
If you have the phone off, hold volume up button while connecting to usb, it should enter fastboot (blue light), which also may be used for some recovery, if the phone has been unlocked (or for the unlock itself).
If any of those modes are available, the phone should be possible to recover.

I have the same issue. My sony xperia xz1 G8342 got sudden dead. (Before dead, I remember I disabled "Developer Mode"). Now its not response by any mean except charging sign when i connect to Power source or PC. Xperia Flashtool shows "device connected with USB debugging disabled".
So, How Can I enter flash mode or fastboot mode? Is My phone recoverable? Please Help.
Thanks
Yesterday I was struggling with my XZ1 Compact and came across this thread that gave me some light to get my mobile phone back.
I guess it's way late for Karl now but just in case, I'm sharing my experience. I was working on my device to get LineageOS 18, as I'm a total newbie with roms I followed the different articles that were posted on Getdroidtips for this particular case: Unlocked bootloader, flashed TRWP and installled lineageos. But then I realized it would be good to have Google Play for restoring my files and apps, but when tried to reboot into recovery mode to get Gapps flashed, Black Screen Of Death started.
After that
with the phone plugged to the pc it wasn't recognized as a device (so adb or fasboot where useless)
the only thing the phone reacted to was to press and hold power + volume up (either for reset or power off)
but no matter what, next boot again BSoD
Tried the Xperia Companion but it prompted that repair was not possible as bootloader was unlocked.
Eventually found this life saver

From there, using fasboot I could reboot the device back with the LineageOS. I was still having issues with recovery boot but I'll post that on a different thread.
Thanks again to everyone for sharing thoughts and tips!
