If you started once in fastboot mode it should start again... Keep the power button and volume up pressed with usb connected until it boots in fastboot.

[Q] - TF201 - booting big problem :(

after installation: recovery-clockwork-touch-5.8.1.8-tf201.zip
think my tablet is broken: (
Do not start!
if I want to run in recovery mode (PWR + Vol-down)
I have just read:
Android cardhU-user bootloader ,2.10 e. relased by "WW_epad-9.4.2.15-20120221" A03
Booting recovery kernel image
and nothing more
tablet hangs on this screen
What can I do???
ADB device not found
only works : APX mode
How about fastboot?
Sent from my Transformer Prime TF201
How can I run mode fastboot?
I choose at startup:
recovery mode - pwr+vol-
APX mode - pwr+vol+
any other combination?
RMA is probably only
http://forum.xda-developers.com/showthread.php?p=22897771
There is no APX mode here. When booting with vol -/power, and doing nothing after, you must face a screen with three icons. You go on the middle icon with vol down and validate by volume up and you're in fastboot mode.
When booting with vol down + power then immediately after volume up then you boot in recovery mode.
Are you sure to do the right thongs?
the problem is that when booting with vol -/power, I've screen with "Booting recovery kernel image" and nothing more!!
I don't have with three icons

No,

have you tried to install the drivers in apx mode?
Yes,
APX it works very well, but nothing can do about it.
When booting, are you trying to boot into recovery or is it automatically booting to recovery.
After flashing the recoveries that Roach has in his thread, you have to let the tablet try to boot normally. This is the point at which the recovery is actually flashed.
When you flash the zip it puts the files to the staging partition and then when you boot normally the staging partition flashes the new recovery.
I hope that all makes sense.
Basically if you haven't tried to boot normally since flashing the zip, then the flash process has not yet completed.
Well, I had the same problem today... and am in the same situation... rebooted the system after flashing and it just sits at the screen trying to boot into recovery... Can get into APX but not into recovery or Fastboot.
I guess I either send it in for service, or wait for NVFLasher.
Well after some long conversation with Asus, basically it is bricked. I can send it to them at my expense and they will give me a quote on repair. They said according to their records my serial number has the bootloader unlocked and is therefor off warranty.
This is true, but I just wanted to offer an update on my situation..
great , i think i did the same thing
can you pass me the contact?

Bricked Xperia Z tablet

Hey guys,
I've got the xperia z tablet (16gb wifi only)
and I had unlocked it, the other day I saw it finally got an OTA update, so I let it update.
apparently that was a bad idea?, I was stuck with the broken android symbol every time i attempted to start the tablet..
I tried the sony software, the recovery thing it has. That has only made things worse, now the tablet refuses to start whatsoever.
Can anyone point me in the right direction? I'd appreciate it very much.

Hi
I had the same issues when I flashed the wrong ROM. Nothing worked no power light or anything.
Now I can't remember exactly what I did but I started to press buttons and I'm sure that holing the power button and the vol up for a while made it start again and it displayed an error and then went into flash mode .
As I said I'm not sure which buttons I pressed but I know that I held them in for a while
Try using Flashtool... Im pretty sure you can rcover it by flashing a FTF file.

So there is hope. :highfive:
I think I found the testpin. My sgp311 has started to blink after being dead since November, when I bricked it.
I don't have the device pack though.. Do you have any clue on how to find it? I think I just need the sgp311 SEMC package to resuscitate it now... Hopefully...

get the stock ftf file and flash it using flashtools, I was in a bootloop and it worked
i know its an old post but i have to try
i m in a boot loop and i want to find the Fed file in order to do a fastboot....
Can someone give them??
I test my tablet SGP321 with many ROMs.. I end up going to boot loop... Crashes and stuff but I always recover from it.
The things I do before doing anything insane with my tablet
1. Take backup off apps/data
2. Always enable debugging and Unknown Sources
3. Keep the backup of the ROMs
4. Always have the xperia flashtool on my computer
Here's what you can do..
Press and hold the Power button and the Volume Up button for ten seconds until you see a white light flashing three times. While doing this somewhere around in 5 seconds you'll see white led flashing once, but keep on pressing those buttons till it flashes next three times.
After that your tablet will be turned Off.
You can put your device in flash mode and flash a new ROM from Xperia flash tool.
If you get the error "Unknown sources and USB debugging must me enable for flash mode, then your option can be to flash the ROM from fastboot.
Download a ROM (CyanogenMod or any with custom recovery).
Flash the boot.img via fastboot and reboot your device.
Once done you should see a led lit up while the device is booting (pink/magenta color in case of CyanogenMod).
Press the volume up/down button and you should be able to go to recovery mode.
From here you can recover your device easily
And before you do anything make sure you've charged your device well.
Good luck

Xperia Z Ultra Stuck on Sony screen

my xperia device is stuck on the sony logo. wont pass that part. doesn't go into flashmode or fastboot, nothing. what can I do plz I need help. cant use flashmode on the pc as the computer never recognizes the phone bcuz it doesn't go into fastboot mode.
If your phone even starts, then fastboot and flashmode should work just fine. What's the last thing you did before it wouldn't boot?
1. Hold VOL UP while plugging it in the USB on your computer. The LED should get blue
2. Either use fastboot through command-line or use QuickIMG to boot a custom kernel with recovery.
3. Flash or restore a ROM

Do the following exactly as outlined.
1- with the phone DISCONNECTED from your pc or charger, hold the power and up buttons until it vibrates and turns off.
2- open the flashtool and select an ftf to flash, and wait for the message that asks you to connect the phone in flash mode.
3- the phone must still be off. Hold the down button and connect the phone to the usb port in the pc. The flashing will start.
I tried that it goes back to the sony logo.

How did you try to unroot? It's weird if you don't have working fastboot or flashmode, and without those, you're pretty much screwed. Those two should work even if you screw up big-time, like flashing a wrong kernel, but you must have done something weird if they stopped working?
And let me get this straight, you are pressing and HOLDING the volume buttons when you plug it to your computer, right? Make sure that the device is completely off by pressing and holding POWER + VOL UP. It'll vibrate a couple of times. Note that you're not supposed to be connected to the computer, since it'll then just boot again.
Then press and HOLD VOL UP for fastboot (blue LED), OR VOL DOWN for flashmode (green LED flashing shortly)
You probably already know these steps, but we have to make it absolutely certain that it's a hardware issue, and not an issue with the thing you do

I was going to flash the stock rom using flashtool right but everytime i tried to put the phone into fastboot mode it would go to the battery icon. At this point the phone was working fine. But no fastboot mode at all. Then i factory erased the phone through twrp. After that it doesnt boot up. Just sony logo no led lights. Even if i do vol up or down. Straight to the sony logo. Vol up plus power button, vibrates couple of times. I redo the process and it goes back to the sony logo.

The thing is that the screen shouldn't power on when you enter fastboot. The only thing that should go on is the blue LED. I don't use TWRP, and I don't know how it wipes stuff and if it only deletes user data, or if it formats the system. If it does the latter, then it literally wipes the system partition, making it empty, so if you ever format the system, you should flash a new ROM ASAP. A little late for that now though, but I'm still not convinced that fastboot isn't working.
ONE LAST TIME :laugh:
NOTE: The device should be disconnected from the computer.
1. Turn the device OFF by holding and pressing the POWER button and VOL UP. It should be disconnected from the computer by now. Got it? Nice.
2. Plug the USB-cable in the device first, since it's easier to plug it into the computer. Do not plug it into the computer yet. Only the Ultra.
3. Now HOLD VOL UP. Just hold it in.
4. Stick the USB cable, which is already inside your Ultra, to your computer WHILE still holding VOL UP.
5. The blue LED above the screen should light up now. The display should not power on or anything else. The blue LED is the only thing that should turn on.
Still nothing?

Check whether the drivers have been properly installed in ur PC. If u can't get into flashmode try another system to flash the ftf. Procedure hold volume down while connecting the usb to plug. U will see a green led blink.

The TA partition is where your DRM keys are. It's a good idea to backup those keys in case you want to revert to complete stock in the future, or when you need to send it in for repairs. Unlocking the bootloader will remove the keys, but since your device was - weirdly enough, already bootloader unlocked, I don't think you even had DRM keys to start with, which is again, very weird.
No biggie though. Gone is gone. The reason why PC Companion told you that it's been modified, is because you're rooted, and it knows it, so you'll have to unroot before you update. That's only if you're updating through official channels, but you have a second alternative; Flashtool. It allows you to flash stock Sony ROMs, or FTF-files.
But you're saying that you flashed a stock 6806 ROM now, and that's what? 5.0.2? Why don't you just download the .368-update (Android 5.1.1)? Then you'll be on the latest version.

Hard Brick ?

Ok, I just want to know if my phone is hard bricked, or if I still have a chance...
I tried to install an update (121 to 170 for plk-l01) on my rooted phone, with local update. It didn't worked, twrp show errors everywhere, and after turning off know i can't access the recovery. when I press on vol+/- and power for 10-15 second, it vibrate but nothing else.
Is there anything I can do ? my phone isn't recognized by my computer, by the way...
Why you did that? You can't update rooted phone

Try to boot into fastboot (phone turned off - connect with data usb to the computer - vol down + power on). Extract rom which is currently installed or higher (for your respective model) and flash from it:
fastboot.exe flash boot BOOT.img
fastboot.exe flash recovery RECOVERY.img
fastboot.exe flash cust CUST.img
fastboot.exe flash system SYSTEM.img
Reboot.

If anyone have any clue on how to force recognizing the phone storage, it might really help ^^
That is what my phone is doing, I tried to upgrade to marshmallow though with no root!! I put the zip in the dload folder and went through the upgrade process everything went through the phone rebooted and now its dead. Blank screen and if you hold power after a few seconds it will vibrate but that is it. I presume its hard bricked? no matter what combo of buttons I press I cannot get it in to fastboot.

ok I'm looking for a solution for hours now... so I just lokked how works our phone and I think the trouble must be in the preloader, because I can't even make my phone being recognized by any computer and I can't access to recovery.
I found this :
http://www.droidgyan.com/soft-brick-vs-hard-bricked-vs-broken/
Which could help. I'll leave that topic on for some days (if it could help someone) and I'll open a new one to know if there is any easier solution ! thanks and good luck.
I sorted mine, it was only 2 days old so I got it replaced by the shop I bought it on. I would say it was something like a pre loader from what I saw. I have never bricked an Android phone and I must have had 15-20 of them since my first HTC Magic and before that Windows Mobile which again I messed with tons reloading with all sorts of ROM's!! These phones are wayyyy too sensitive to being messed with, I always remember though that you never mess with the boot loaders, but it looks like these updates do to get it bricked to that point.

I just hard bricked my Honor 7 the same way. Is there really no solution? Other China-Phones are pretty much unbrickable, since you can always fix it via the preloader. No such luck here? Back to the shop and hope they actually replace it? While I admit it was stupid to just hastily start the OTA while having twrp and not stock recovery (no root, though), this is a terrible design flaw on Huaweis side.
Anyway... any hope or no chance?

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!
