[Q] Flash Mode Not Working

I recently flashed DooMKernel for my Xperia SP via fastboot. After that, I flashed the kernel (only kernel) of the stock 12.0.A.2.254 via flashmode. However, after that, both fastboot and flashmode are not working on my device. When I hold either the volume up/down button when I plug my phone into my computer, the notification light turns blue/green for a while before turning red for a while and booting normally. I have already installed the fastboot and flashmode drivers successfully and I recently upgraded to Windows 8.1 x64. What can I do to fix this?

The funny thing is that it actually does turn blue/green. That goes to show that it's working, it's just that after a certain time of being in that mode, if there are no detectable data transfers, it will restart.
Also, have you disabled driver signature verification and test signing on Windows 8?
This message was sent so that I'm slightly more useful

As CallMeVentus said it works but then reboots. If you're using flashtool you can first select the firmware to flash and when you start it will ask for you to plug your phone in flashmode. Do it and it should directly copy the files, so your phone will stay in the right mode.

CallMeVentus, I have already disabled driver signature enforcement in Windows 8.1 and have reinstalled the flashtool drivers three to four times already. When I plug the phone in fastboot or flashmode, Windows tells me "USB device not recognized". However, when I plug it in as MTP, it detects the device normally. I have used many different USB cables and the problem still persists. Does it have anything to do with my recent upgrade to Windows 8.1?

Cant connect to PC and access my data

Hey guys,
long story short: I flashed my device and now my pc wont recognise the usb-connection between my phone and computer. The hardware-manager describes as if the phone cant tell the computer that it is a z3 compact.
Errormessage: Unknown USB-device (Cannot get the device description)
*something like that*
what I did to troubleshoot:
- reflash the device with firmeware: A.1.264 (without this strange script)
- reflash the device with the concept preview (without this strange script)
- installed PC Companion from Sony
- Linux cant see the phone, but can flash it
- USB-Debugging wont work as well
Nothing worked for me so far. Anyone an idea what to do?
thanks in advance

Some roms come with the usb functions disabled, removed as bloatware. So it's possible the first rom you tried didn't have the usb functions installed.
Do you have the correct drivers
Presumably flashtool can see your phone and it's still charging, so I'm sure the hardware is ok.
Did you try a repair with PC companion?
Do you have a different usb lead you can try?

Hey,
thanks for your answere. I found a "solution" to connect the phone via fastboot to the pc and with this I could do a complete reset with the PCC. When the phone is booted however I get the same error message over and over again: Cant get a device description!
Maybe you can look up the specific driver which is used in the device-manager so I can force windows to use this one?

Did you install the ADB drivers that come with flashtool? Look in the install folder for a folder called 'drivers' run the exe in there and tik the fist two and then Z3c.

Yep, all three unsigned drivers.

Can't enter in flash mode

Hello to all,
I would like to install a custom ROM but unfortunately my phone doesn't want to enter in flash mode! Once switched off, I plug it to my computer while keeping vol down button pressed but instead of entering in flash mode, it displays the battery charging icon.
I hard reset the phone but the problem still remains. Any idea.
Thanks, have a nice day!

My guess is either the USB cable (did you use the OEM cable?) or the drivers (does windows recognize your phone?). Removing the SD card or first entering recovery were suggested earlier (http://forum.xda-developers.com/xperia-l/help/update-volume-connect-doesnt-t2613733). But more experiences Z3c owners may have better ideas...

Using flashtool:
Turn phone off completely.
Start flashtool, choose flashmode and choose which firmware you are going to use. Tick Exclude TA.. Click on flash.
It will start preparing the build and after a few seconds it will ask you to connect the phone.
Plug the phone in while holding volume down, as soon as flashtool starts doing something, you can let go.
If you don't know how to use flashtool then I urge caution, Sony's aren't like flashing a Samsung, it is actually possible to brick your phone with flashtool. There are lots of questions on 'how do I fix my phone?' in this Q&A thread from people who didn't read up on what they were doing.
Recommend you read bilboa1's great guide on what to do, starting with backing up your TA partition..

Thanks for your answers but I think the mini usb from my phone must be dead.
About Flashtool, I can't use it because I can't go into Flash mode! Moreover, my phone is not recognized by windows. I tried with several usb cables and computers when I plug it, I don't have any MTP or PTP choice, it can only charge..
On Windows 10, devices is not recognized and Window 7 see it as a 5880!
And I tried to remove SD and SIM cards..

If the USB lead was dead you wouldn't get the charging icon on your phone.
Have you installed the Sony drivers.
You also need to run exe in the Drivers folder within Flashtool, to make sure you have correct flashomde drivers available. Installing these drivers is very difficult in Windows 10 and it require restarting the machine in safe mode, and going into the advanced settings to disable driver signature checking, this how to video is for windows 8, but you'll get the idea
Have you installed ADB?
Sonys PC Companion should set you up with the correct connection to your PC

Have you tried other USB cables?

Yes, I've installed PC Companion, adb drivers but nothing appears when I use command "adb devices". I've also installed flashtools drivers but deactivating drivers signatures in Windows. But when I try to flash, flashtool ask me to turn my device in flash mode (switch off then volume down + power) but I can't do that.
I've tried several usb cables. Some are charging my devices, some are aren't but none of them allows me to data transfer!
I've also tried to force MTP or PTP usb transfer in developper option, it doesn't work more..

Do you have any warranty on your phone, you could be right that the usb socket is damaged somehow, but it's strange that you can still get a charge through it.
Your only chance at moving to a custom rom change is flashfire
This should let you flash a rom without recovery.
Edit: Flashmode is just holding down just - volume button, not volume+power
Obviously your chances of rescuing a failed install are going to almost zero without recovery and flashtool, so be very very careful about what you try and flash in flashfire. Read up completely that the rom you want to flash is going to work pushed on top of whatever you are running at the moment.

For anyone who might be interested, sometimes you have to try a USB 2.0 port or just a different port. I had the same problem while using a usb 3 port, switched to 2.0 worked like a charm.

Try to open the back of the phone and removing/unplugging the battery wait 5 seconds and then put it in again. Then try holding down the volume down button while you connect a usb cable.

Device won't be detected in fastboot mode

My device is H811 running 10N version (rooted), but I'm unable to update it using because it won't be detected once it goes into fastboot or download mode. I have tried many drivers, and different PCs (running different OS, Windows 10, 8.1, 7) but still can't get it to works. Is there something I'm missing?

No it doesn't. LG Up detects it when phone is On, but when LG Up restarts the device in fastboot, it says no devices connected, even when drivers are installed. Yes, the USB port is 2.0, and it can't be problem with port of phone since it is detected in normal mode. I will try these drivers and let you know if it works. Thank you

Okay, that's the problem actually. I was confused between fastboot and download mode. When I press volume up and connect the cable it boots into fastboot mode instead of download mode. What could be the problem?
BTW here is the log from fastboot mode:
usb_error();transaction failed.txn_status = -1
usb_read(); DONE. ERROR. len 64
SECURE BOOT: DISABLED
LOCK STATE: LOCKED

can you do a factory reset.? can you try again to go into download mode.. maybe use an app that has download mode recovery mode one click on phone to take you there.?
its weird .. something not right when vol up and connect usb.. doenload mode should pop up. with screen showing usb icon.

I had the same exact problem for 6 hrs yesterday and i came across your thread and the problem is when you do adb reboot bootloader, and your phone doesn't show up on your pc under 'Computer management > devices', the driver says unsupported, follow this video starting around 4:50, you'll find all the drivers that way and it'll work right away

PC will not detect Mi Mix

kernel: 3.18.31 perf-g0bf156d-01070-g4aac0b4a
Phone came unlocked from seller HongKong Goldway on Aliexpress.
I have tried to download the usb drivers for my laptop which is on windows 10 and a PC running windows 7 and did that update driver thing and tried to use the downloaded winusb_inf file. I've also tried going into windows INF folder and right clicking that wdptmp.inf file and trying "install".
The laptop says Unknown USB device ( Device Descriptor Request Failed) and the PC says Unknown Device. Both are under the USB section on Device Manager
I installed ADB Fastboot tools, turned the phone off and held power + vol down to go into "Fastboot" where it loads a white bunny with a green russian hat holding cords behind a green android robot. Fastboot on the computer doesn't detect any devices.
I also tried Mi Suite and nothing detects. I am using the original usb type C cord and I also tried 3 different usb Type C cords.
Any help guys?? (Also I can't find any update app icon anymore...is that new?)
I want to install TWRP and root so i can do that performance tweak for the mix. and load up a custom rom.

Sounding like you might have a vendor ROM installed, you should follow the guide in the guide's section, follow the guide for installing twrp with vendor ROM. The unlocked bootloader is a sure sign the vendor installed their own ROM.

No follow the guide for the correct install of driver's, disable driver signature in windows 10.
http://en.miui.com/thread-345974-1-1.html#post_6279092
There are 1000s of people on this forum who have done the same thing you are trying to do. So basically you are trying to get China dev ROM installed through miflash, then your PC will recognize it then you can install the rest after.
Search vendor ROM mi mix, even if it isn't vendor ROM sounds like you are still going to follow the same guide.
Have you tried another PC? Don't see anyone else complaining about not detected

i have tried 2 and 3, nothing. method 1's steps didnt really make any sense to me so i didnt do that one.
im dumbfounded because im reading posts on XDA and MIUI forums and theres like 30% of mi mix owners that never found a solution to this while the other portion did easily. I have no idea what I could be doing wrong and I'm starting to think it's the phone and not my laptop. I also found out that when i go into fastboot mode on my mix, it only stays in fastboot mode for like 30 seconds and then ejects itself out of fastboot mode (im not sure if this is normal)
Ive also tried to download older official china roms and tried updating them through the mix's updater option. nothing. what in the hell is going on here?!??!?!

Hey thanks for the reply.
Do you see picture 1 you uploaded, where its device manager and you can see Portable Devices and there you have that One A2001 device that shows up?
I don't have ANYTHING that pops up under portable devices or portable storage.
Mine only has a notification under the USB serial bus controllers. Mine says only this
Now, I know what you mean by trying to install the MTP USB Device, except you can't do that when you have this kind of USB error because it doesn't even detect a device to even update a driver to MTP.
If you read back you'll see that I have tried installing USB drivers before, I've also used the MiFlash tool to install drivers through there. Still nothing. If someone can find a fix I'll paypal them a few bucks for their trouble because I seriously don't know what to do from here. I've searched many forum posts on here, miui forums, reddit and everyone seems to at least have something detect in their Device Manager as a device. OR some people are able to detect their device in ADB boot but mine doesn't and mine also can only stay in fastboot for 30 seconds before it kicks itself out.
I also don't believe I have a vendor rom because it only has 4 numbers despite coming in the mail already with an unlocked bootloadeder.

Try right clicking on the unknown usb device and if it shows that you can update your driver software so try doing what I sent in my first reply (I hope your phone is connected to your pc in this picture ?)

phone is connected. and ive already tried what you're guide says. except this is what it looks like on mine\
no MTP option at all
when i uncheck compatible hardware box (there is no mtp as far as i looked in the options)
I believe yours gives you the MTP option because your computer picked it up as a device. Whereas mine is having some kind of USB error and doesn't know wtf is plugged in? The thing is, it will detect my Redmi Note 4 Global with no problem... so

Damm.
IDK maybe there is a problem with your charging port.
You can try another thing, If you have another phone with a USB type C port and you have a USB type C to USB type C charging cable, then connect these 2 phone and try transferring files from one phone the to other (Did it with my phone and my friend's Nexus 5X).
