[Q] Flash mode won't work - Xperia Z1 Q&A, Help & Troubleshooting

Hi!
My C903 cannot access flash mode. The led is flashing red and green like a second, then dissappear. Then I have to hold power+vol up to be able to start the phone. Everything else works great, fastboot and everything. I have flashed roms on this phone work flashtool before and it has worked great. I have DoomKernel and rooted stock. 290. Anyone know why the flash mode won't work. I have nandroid backup and unlocked bootloader, so I can try any suggestions.

You turn off your phone then when it is off you keep pushing volume down, connect to PC and the PC do not recognize the phone?

Win 7. It worked earlier. I have not changed anything, at least not in Windows. I guess it's the phone.

Follow these steps....After clicking on “Flash” Button FlashTool will prepare file for flashing.Now enable USB Debugging on your phone and enable unknown sources option in your Xperia Z1 and switch it off. When prompted the notification of connecting your phone, connect it in flashmode.Press Volume down button and then insert usb in phone, you will see red and green light blink once, it means phone is connected in flashmode now.
As soon as phone is detected by FlashTool, flashing beings and wait till it is finished.......
Where is ur fon getting error in above procedure?????

Actually the only things that don't work is flash mode and that I can't charge phone while turned off. It boots into system and starts charging. Anything else works. When I try to flash with flashtool it says connect phone after preparing files to be flashed. The red/green led flashes, but no flash mode. Everything with the phone works, but not flash mode...

I don't know exactly why you want your phone in Flashmode but probably because you want flash something so if you don't mind wipe your phone try use PC Companion and repair the phone to stock, maybe is the custom rom making problems.

[Q] Flash Mode Reboots while connected

Hi, so I have a stock ICS rom on my lt30a, and im trying to put the Jelly Bean update. This is the first time im using flashtool but I did my research and knew everything I needed to do. One thing keeps preventing me from flashing it to my phone. I put the phone successfully in flash mode, green light, its recognized in flashtool, excellent, then after a short period of time my phone just reboots, shows the sony logo and is charging normally. I think my computer just keeps not recognizing the phone again and again but as far as I know all the drivers are installed.
Any ideas?
Cheers

Ok then looks like usb debugging is turned off goto developer options and turn it on and try flashtool again also make sure to allow mock locations in that same menu
hope this helps
Huh it says in developer options that usb debugging is on. I turned on mock locations and will try again. It could be the problem is with my computer or Windows 8 not flash tool or my phone

Well, thats the way to do it. You must let flashtool prepare the files and only attach the phone when it prompts you to do so.
Tell me what happens when you do it. I cant help you if I dont know if it disconnects whilst actually flashing. Please copy and paste the log from flashtool

Actually one thing I just noticed that my phone is doing which as far as I know has never happened before yesterday is when I hit turn off the phone turns off then reboots normally when it should just stay off. Might this be some contributing culprite. I cant try to flash it right now but i will when i can. Thanks for the help
Edit: Also just noticed that windows drivers is having trouble downloading S1 boot drivers. I dont know if this is relevant

No need to say thanks, just hit someones thanks button if you want to say thanks.
That is a seperate issue from 303 or 195 FW, I beleive it is gone on 223 and 498 FW
But what you can try is to press volume up and power button to hard reset the phone. Do it untill it vibrates once AND THEN KEEP PRESSING UNTILL IT VIBRATES 3 MORE TIMES. Then try connecting in flashmode

I should have asked this but is there actually a time out for the flash mode?
Power and volume up together until you get three vibrations. There is no time out for flash mode

Could the problem be driver related? When im in flash mode my computer starts to look for S1 boot but doesnt have enough time for it to download the necessary driver. If so can i get this driver from somewhere else?

I hope you have USB debugging turned on. For flashtool you need this.
Turn off your device. Open flashtool and click on the lightning. Chose your stock rom. Wait until the command comes to plug your phone. Hold volume down and plug your phone in. Wait a few minutes. You are done.

If you haven't got debugging enabled the Sony Update service (SUS) will do it, this will only work for locked bootloader

I hope someone is subscribed to this thread. If i use flashtool, does it mean there is no way someone can retrieve my deleted photos? Am sending my phone to the service center and i dont want them getting some private photos
If you have a broken touch panel but the screen is still good enough to see, all you need to do is get a USB OTG adapter/cable (micro USB plug on one end and a computer USB socket on the other) and a USB mouse. Plug the mouse into your Android device via the USB OTG and it will give you a mouse pointer on screen which can be used to do any single touch action you would normally do. This works in TWRP's recovery too.

[Q] lost usb charging on mtp connection

could I have lost this after a failed attempt at getting into flashmode? And how to get it back? PCC or flashtool doesn't see the phone. USB charge works in MSC mode but still PCC and flashtool cannot see the phone. I've hit the little red button but no change. So I can't see away of flashing or updating via PCC until this is resolved.

Try going into flashmode this way.
Hold volume down button, attach usb cable, keep volume down button pressed and then press and hold the power button until something happens (LED blink or vibrate) then let go of all buttons.
I had to do that on my Xperia T because getting into flashmode the normal way didn't work

Thanks for the suggestion but it didn't appear to make any difference but something I realised is that I might have been holding the volume - fir too long. Also the green LED indicating flashmode doesn't stay on just flashes briefly. Still I was able to get PCC to see the flashmode and 'repair' it but it has made no difference. In USB mode MTP the battery is not charging hen connected to a PC and is when connected in MSC mode. I realise it is not hugely important but it would be nice to have it working the way it as two days ago PCC doesn't recognise the phone nor Media Go; maybe it is pc driver issue though I have uninstalled and reinstalled the pcc software.
Install flashtool and run the drivers.exe from the driver folder in the instalation folder of flashtool. Choose flashmode and fastboot drivers

At the start the phone went to flashmode as i hold the volume up button , and also the soft / hard reset gave me a vibration feedback , but for some reason i had to wait a night for test to flash the stock firmaware and when i woke up the day after the phone was in the situation that i described in the first post.
Do you advise me to put the phone in charge even if the phone don't give me a feedback when i plug the charger?
Hi Kidamundi,
I've the same issue. I've tried to update my cyanogenmod 10.2 yesterday. Now the phone is dead.
I've tried the reset (power and vol+ until 3 vibrations), then I've plugged in the charger over night but the phone won't charge.
Now I've blinking red light (2 times) if I press the powerbutton.
I've no idea where is the problem ...

reanimated
Hi,
I've reanimated my phone!
First of all I've charged my Phone, but it has only worked with the rubberband on the powerbutton. After 1 hour charging I've connected the phone to flashtool and have flashed an old stock rom. After flashing my phone has booted.
But still 1 problem I have. If its powered off the phone will not charge. No red light, no animation on the screen, nothing. I think its a problem with the kernel but I don't know it. Do you have an idea?

my xperia v
i have the same issue with my xperia v. phone won't boot. whenever i hold the power button. red led light just blinks 2x/3x. i tried taking it to a service center and they said they have to change the lcd together with the whole base. which will cost me 12,000 pesos. i bought my phone for 12,400. so i think its really stupid to have the lcd replaced. i'm gonna try what you guys did and update you if this works. good luck to us guys.
ps: when i unlocked the bootloader it did a factory reset and i think what happened is it disabled usb debugging that's why it won't turn on.
sorry for the double post guys. i really wanna fix my phone. i left it charged for at least 1 hour. i used this program called update service. it actually detected my phone but it gave me this message that reads "the phone contains modified software that cannot be updated" does my phone still have a chance? ):

"For flashtool, Unknown Sources and Debugging must be checked in phone settings"
Turn your phone off. Open flashtool and press BLU. Then go into flashmode (volume up while plugging usb in). You do not need usb debugging to unlock/relock bootloader via flashtool

Red light blinking is because your phone voltage is less than can running kernel and charging program. You need like a car put together a battery
I dit it after trying all button, software, etc rescue.

Brick after format microSD by CWM
Before few days I successfully managed to gain root access, unlock the bootloader, and finally install a functional CyanogenMod ( 10.2.0 stable) on my Xperia V.
(after one softbrick, when I learned how to use flashtool and fastboot).
Yesterday I was install in to the phone a new 32 gigabytes SD card, but Total Commander file manager in the phone didn't show contents. I decided to format this microSD. The mistake was probably that I used to format ClockWord mod in the the phone. Twice times I check whether I will formated external microSD. And I format it to the default format. After format I confirmed the fix root privileges (I put YES) and then just reboot.
However didn't reboot phone and no reaction, no led or vibrations. Bricked.
I take SIM, microSD and battery from phone.
After instalation battery back, my brick "symptomes" are same like Kidamundi and others:
-if i try to turn on the phone the red led blink 2 times, pause, 2 times, pause, etc (no vibrations)..
-if i try to push the buttons for soft/hard reset the red led blink 2 times, pause, 2 times, pause, etc (no vibrations)..
-if i connect to the pc and try flashtool, answer is "USB connection is not in Debugging mode, Device disconected",
-if i connect to the pc and try fastboot, "waiting for device"-if i connect to the pc no response even if i try to hold the voume up button during the connection( i tried also with flashtool)
-if i try to connect the phone with flashtool opened ,and i press power button the red light still on like 5-6 second and flashtool recognize the phone but as the red light turn off flashtool show "device disconnected".
Is relock bootloader safe way for me too (with succesfull Cyanogenmod before bricking)?
And which is next step after relock booatloader?
I tried to explain the problem as better i can, and sorry for my english. Thank you.

-if i connect to the pc and try fastboot, "waiting for device"-if i connect to the pc no response even if i try to hold the voume up button during the connection( i tried also with flashtool)
-if i try to connect the phone with flashtool opened ,and i press power button the red light still on like 5-6 second and flashtool recognize the phone but as the red light turn off flashtool show "device disconnected".
Is relock bootloader safe way for me too (with succesfull Cyanogenmod before bricking)?
And which is next step after relock booatloader?
I tried to explain the problem as better i can, and sorry for my english. Thank you.

I had no echos from flahtool and fastboot. Service confirm hardware issue. I have hard brick, but relation with my Cyanogenmodding is unsure, inconclusive. I'll try complaint procedure.

Though I hold vol.+ and power ,device vibrated ,but nothing happen.
Dont press power button for fastboot mode just do power of if its vibrate 3 times than your phone is off OK? Next step is connect ur USB cable to PC than press only the vol up button !!!!!! not the power button!!!!!! and then connect ur phone with the USB cable so then just make fastboot flash bootimage Form a Rom of your choice vor stock firmware

Have you tried the hard reset button?
Under the flap next to where the sim goes, is a tiny hole. You need a pin to press and reset.
Edit: Do you have ADB installed? Have you installed the Sony drivers. on your PC?
You also need to run the 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
All of those need to be in place before flashtool will work.
Does it go into flashmode? Make sure it's turned off, start flashtool on your pc, then hold the volume down while plugging in the usb cable. If flashtool recognises it then you can follow bilboa1's great guide. You will probably have to start from scratch, old firmware, root exploit, recovery etc etc.

I installed all the drivers correctly , hard reset yellow does nothing. Now I use window7 to save my phone , I have found sth. useful. The device cpu send sth. about QHSUSB_BULK driver . Which means the the most basic software had lost. Now I am searching for the device bootloader .

Thread here lists installing QHSUSB driver, worth a go perhaps?
There is a thread dedicated to rescuing hardbrick devices

Exactly the same happened to me this morning. I had not time so I left it and came back at midday. After trying to reset it many times it finally turned on (maybe 15 min trying), but the USB port completely died... Then I notices son humidity in the two cameras crystals. The phone was working great, I even play asphalt 8 for 20 min and nothing wrong happened. I've just sent it to repair. Tech guy told my that maybe the motherboard is compromised.
The only thing I can surely tell you is keep trying, it worked for me.
