Try pressing the power button when green led. It may be stuck in flashmode.

If it vibrates 1 time then let go.

Then see what happens.

Should get a solid red led, meaning dead battery.

When battery is dead you will get a red led until enough charge to boot into offline charging with the on screen icon.

You can also try a power + volume up button reset for 3 vibrations. That will turn it off and allow charging.
[Sony Cross-Device General] Toledo_JAB:
Just Google Flashtool.

They have their own site to get the latest version.
[Sony Cross-Device General] Toledo_JAB:
Sounds like a bad custom kernel.

If you can get into fastboot mode (blue led), then find a good working kernel boot.img and flash it with flashtool and fastboot.

If it has an unlockbootloader then Pc Companion will not work.

Also, if it is a bad custom kernel, then flashing a stock ftf file will also not fix it.

Thanks for replay,

This phone was never modify has original software on it.

Yesterday I successfully connected externally my battery from Samsung phone and system boot up up to screen without icons.

Looks like bad battery to me.

My xperia Z1 (C6902) is soft bricked.

I flashed MIUI7 (4.4.4) via twrp but i lost recovery. I was rooted with usb debugging on and tried different methods to install recovery (fastboot, miui updater, twrp manager app) but unable so, i tried to revert back in stock rom by flashing stock firmware 14.3.A.0.757 via flashtool but stuck into flashing data message. Waited for more than an hour and thirty minutes but nothing happening. After removing usb and tried to on, it appears SONY logo than following message. "this software update failed. make sure your phone is connected to computer and try again". Whenever i connected to charger, it shows red led and restarting again and again.

Did i missed something or i am not doing correctly??

Hi guys,

After doing many things, my phone is having red LED blinking now (from no responds when plugging in to PC/wall charger or pushing power button). Could you please tell me what should I do now? Just leave it charged until stable red or green led show up or just plug it out until battery die?

Thank you.

Xperia Sola apps crash errors & flash mode not working

Hi there guys,

I have an old phone Xperia Sola. Yesterday I did a factory reset from phone setting. Factory reset was successful. Phone restarts but every app starts to crash as soon as phone boots and I am unable to use the phone. Tried PC companion can't get to the flash mode, Tried Flashtool same issue can't get to the flash mode. All drivers are installed but phone doesn't show up in flash mode. It does boot normal but on each restart after sony and xperia logo there is a windows saying (Android is upgrading... Optimising Application 0 of 84) this process runs and then again errors and phone reboots like I just performed factory reset. It does showup in fastboot but not in flash mode kindly help I am stuck here.

Notes:

1. Phone is not rooted/Dont know about the bootloader whether is it locked or unlocked.

2. I am using windows 10 so kindly if you guys know any issues related to drivers on windows 10 do let me know and share drivers If you know about any. (Using windows 8.1 drivers and technique) (Now I have installed Windows 7 but same issues on Windows 7 too)

3. I have installed adb but flashtool show no device even when my phone is connected. (Screenshot is attached)

4. I can't turn on usb debugging mode because I can't use the phone.
[Sony Cross-Device General] mirhl:
Open device manager and make sure drivers are installed.
[Sony Cross-Device General] ireaper4592:
mine was i have a m2 and i flashed cwm through twrp recovery and then did wipes system,data,cache,davlik and when i went to go back option was not there so i tried to reboot back into recovery and now i get no response from device gonna try charging for 24 hours and see if i can get fastboot or flashmode to work hopefully any help would be appreciated
[Sony Cross-Device General] Usman Aly:
Well I have tried each and every driver on win10 & win7 none work. Phone shows in device manager when it is connected in fast boot mode and normal on but it doesn't show up in flash mode there is a sound when I connect my device & device manager refresh's the list of devices but phones doesn't show up in flash mode.
[Sony Cross-Device General] darknessmc:
My xperia SL is bricked when I restart it, just dead no led, no vib, no fastboot or flashmod, nothing, the only thing I get is in PC device manager it changed to QHSUSB_DLOAD and windows is recognize it as SEMC flash device. I tried PCC (doesn't see the device) and flashtool say device connect with usb debugging off. My battery was 48%. I read about this problem here in xda but I didn't found any solution. Is there any suggestions?
[Sony Cross-Device General] nageswarswain:
I think there is no other way than boot repair by JTAG or riffbox.I will let you know if it works for me or not tomorrow. If you found any way to repair then must share it as we both are really unlucky at the time.
[Sony Cross-Device General] darknessmc:
Nothing here except it had red led for 3 hours then dead again.

Update1: I got red led again. I forget to tell you I was at pure AOSP marshmallow.
[Sony Cross-Device General] mirhl:
Which does not support offline charging.

So better for you to flash a kernel supporting it as soon as it has enough battery to enter fastboot.
[Sony Cross-Device General] darknessmc:
No it was caharging for me. I can charge battery without my device but same thing no fastboot or flashmod
[Sony Cross-Device General] cjey:
Due to bad flash i bricked my Z1 (C6902) with message "this software update failed. make sure your phone is connected to computer and try again". Whenever i connected to charger, it shows red led and restarting again and again.

Than my phone is completely dead. I took to sony service center but returned my phone saying that we cant repair.

i thought i will try myself and put on wall charger for more than 24 hrs, i got the blinking red led to no led. Tried to flash, it shows "Device connected with USB debugging off" but nothing happening again connecting in flash mode.

Please help! what should be the next step?

Please help!!!
[Sony Cross-Device General] lenteenes:
After much patients I recovered my phone

thx for your guide
[Sony Cross-Device General] darknessmc:
So, what was your problem and how did you recover your phone?

This is the fourth day at rubber band and nothing happened. Then I plugged out the battery and charge it and plugged it in, the same no fastboot no flashmod no led. Is it the end?
[Sony Cross-Device General] nageswarswain:
Is it possible to recover if the TA has removed??I am getting red led when connecting to wall charger.when trying to connect to flashmode or fastboot the red light turns off for few seconds and again the red led comes in.so what shall I do??
[Sony Cross-Device General] mirhl:
The goddamn rubber band trick, connected in flashmode with wherver tool you want to restore it.

Also, I still don't understand why you say you have lost it
[Sony Cross-Device General] nageswarswain:
I don't know too...the repair boy said I couldn't repair it as the TA partition is wiped...by the way when I was connecting my device to pc it was connected as QHSUB device but now its detecting as semc flash device.I have connected now it to pc with rubber band and flashtool ready but no led is there... Am I going in right way?
[Sony Cross-Device General] darknessmc:
Our internal memory was wiped completely with mm rom, no partitions. I think there is no way to get it work again. I'm sorry to tell you that, accept the situation as it is and go on.
[Sony Cross-Device General] mirhl:
We all had our QHSUB and semc flash device moments, don't worry.

Iirc the first is the hardware-driven charge device. The second is flash mode.

Oh, such a *****.

And just because X made you think Y, it doesn't mean Y should prove X.
[Sony Cross-Device General] nageswarswain:
Yesterday night I used rubber band trick with flashtool ready.after 3 hrs my device charged but nothing happened till next 2 hrs.BTW I charged my battery on a wall socket charger and then put it on my device and tried but nothing happened. Then I put my device on the wall charger but no led.connecting on pc will show semc flash device.so what do u think about the matter.
[Sony Cross-Device General] mirhl:
I once tried to charge XS battery on a wall charger. And you wouldn't believe after an hour it had just enough charge to sustain a stock rom flash and boot into the system (1% there).

Said this, nothing changed in flash tool? Seems weird. Try to uninstall semc flash device driver and see if with windows normal usb driver it behaves differently.
[Sony Cross-Device General] nageswarswain:
I uninstalled all drivers and reinstall only flashmode n fastboot driver..lets see what's happening this time.another thing I have another xperia s.I connect it to flashtool by flashmode but flashtool is connecting to flashmode n after 44 sec it disconnecting.what's the problem.I tried in 3 diff xp systems n with various flashtool versions but same thing happening 44 sec n flashtool saying device disconnected.it is suppose to be like this or something is wrong.
[Sony Cross-Device General] nageswarswain:
[MENTION=4900593]mirhl[/MENTION] I charged my battery on a portable charger for 4 hours so I think it has enough charge for flashing.then I put the battery on device and connect it to wall charge and there is no led.I think it is supposed to be coz the battery has charged.Then I disconnect the battery for few mins and replaced it on the device.

Then I make flash tool ready with ftf and tried to connect my device with vol down.but flashtool said device connected with USB debugging off and the device manager show semc flash device.

So I think now that it is finished.may be my main board is damaged or my TA partition is removed for which it's now unrecoverable.

So please tell me what shall I do.if I will try something else or I have to leave my device as its unrecoverable
[Sony Cross-Device General] mirhl:
Again, if it reads SEMC flash device it means there's something living attached.

Now, being stuck like that is a quite common problem unfortunately. Besides, trying to fix goddamn windows drivers I wouldn't know specifically.
[Sony Cross-Device General] nageswarswain:
If it's windows driver problem then how my other xperia s is detecting fastboot mode??
[Sony Cross-Device General] Toledo_JAB:
I belive that there are drivers for the different devices bootloaders.

I have seen different drivers for the same device when using different android versions.

Try setting up flashtool to flash just the kernel. (exclude all but kernel by check boxes)

When flashtool asks you to connect a device then use rubber band trick.

After flashing with flashmode you need to exit flashmode, on the phone, to start charging.

If flashtool says finished but phone not charging, then do a reset with power and vol up until 3 vibrations. (the 1 vibration reset does a reboot and will cause bootloops until reset again or battery dies.)

If it works you should be able to charge the device but not boot it. (bootloops due to no system files installed.)

Let it charge for about an hour before flashing the full ftf file. The first boot of a rom takes some time and the battery needs to have enough charge.
[Sony Cross-Device General] nageswarswain:
Nice to see ur reply.but I have sufficient charge on my battery as I am charging it on a portable charger.and if I have sufficient charge then the rubber band trick will not need as I think.I have another xperia s and fastboot mode is working perfectly. But flashmode disconnecting after 44 sec.I tried to install drivers in many ways in windows 7 ,xp but its always disconnects after 44 sec.can u give me link to guide to install driver.

I have asked many times that if its detecting semc flash device then does that mean it can be recoverable?? I am afraid that may my device has main board problem or a dead boot.so how to determine these or any symptoms.

My English is bad sorry for that
[Sony Cross-Device General] Toledo_JAB:
http://xdaforums.com/showthread.php?t=2635830&page=11

The link above is a all in one xperia driver pack.

You may need to right click on the program and select run as administrator.

Reboot pc.

Now start flashtool then select flash. Then select flashmode.

Then pick your ftf file on the left. Then in the exclude box check all but kernel.

Then click to start the flash process. When the file is prepared it will ask for the device to be connected in flashmode.

Now connect the phone with the rubber band on.

Once the phone has enough charge it will connect in flashmode.

The pc should install drivers on first connect. (if not already installed)

Then flashtool should flash the kernel.

If flashtool gives error about drivers and stops flashing, then restart the flash process and rubber band trick again.

Do not connect the phone before flashtool asks for it.

Good luck
[Sony Cross-Device General] darknessmc:
Just to explain what I see in device manager, what ever I do, press vol+, vol- ,without pressing any thing, the device has this parameter

USB\VID_0FCE&PID_3DDE and has name SEMC flash device

This name and vendor name doesn't change and I use rubber band since 8 days and nothing happened just red led for 20 minutes and no led for 50 minutes.

I'm in the same situation with [MENTION=5709791]nageswarswain[/MENTION] and we did the same thing in our device and have the same issue.
[Sony Cross-Device General] nageswarswain:
thanks for reply.But i think this is the same driver pack which we are finding in flashtool driver folder.I installed this again but still flashtool is connecting for only 44 sec.Can anyone confirm how much time (maybe 2 mins) flashmode stays connected with pc.BTW after installed drivers when i connect the device the PC detected SOMC Flash device.is it correct or SEMC flash device is correct?
[Sony Cross-Device General] Toledo_JAB:
Do not connect the phone first.

Setup flashtool first.

Then only after flashtools pop-up window asking to connect device do you connect to pc with rubber band.

Flash tool does Not need to recognize the phone to flash it.

44 seconds is enough to flash the kernel.

Please post a screen shot of your pc with flashtools finished for more help.
[Sony Cross-Device General] nageswarswain:
As my fastboot driver is ok I was trying rubber band trick to flash doom kernel v06.elf by PC(command prompt).now my phone is connected to pc with rubber band pressing vol+ from 6 hrs.still no led or fastboot.in device manager its detecting SOMC FLASH DEVICE.the pc is waiting for device saying ( waiting for device)

Is it correct procedure?

And my question is if I will not try to flash any thing in flash mode,then how long it will stay in flash mode?until the battery die or it is suppose to be 44 sec.
[Sony Cross-Device General] Toledo_JAB:
Your fastboot plan should work.

Have you tried to do a power + vol up button combo until three vibrations with the phone plugged in for fastboot flash? With the phone connected and the rubber band on the vol up button, press and hold the power button for about 30 seconds. Any vibrations? If yes then the phone should connect in fastboot mode as soon as you let go of the power button.

Sometimes the phone will try to boot and then lock up. it will stay frozen until the battery dies or you reset it.

Depending on how much charge it can be a long time.

If you connect the phone and get no lights then try a reset with the phone still connected.

It is difficult to know what is wrong with flashmode.

The phone should stay in flashmode until you disconnect it or the battery dies.

I will say that my Xperia X10 will show a green light continuously when connected in flashmode, But my Xperia T2 Ultra only has a green light for about 3 seconds when first connected.

All 3 of my Xperia have a continuous blue light when connected in fastboot mode.

What happened when you used the flashmode and connected the device when flashtool asked?

Any green light?

What did the flashtool log say?

If you are very curious you can change the log level of flashtool to verbose from the toolbar on top before you start the flash.

I really have no experience recovering using fastboot.

I have only used flashmode and rubber band on vol down.

However a few users have been successful using fastboot.

We really need to see the flashtool verbose logs to be helpful.
[Sony Cross-Device General] nageswarswain:
I hold power button for above 30 sec while rubber band on vol+ key n connected to pc.but no vibrations.

I have not seen verbose logs in flashtool.only 4 thing to chose from log level are info,warning,debug n error.so what to select?

I disconnected the device from pc and connect to wall charger but no led.(I already removed the back cover and can easily remove the battery.so I can reset my device by just removing the battery(for how much time).

This is my situation now and what will I do.please help.sorry for my bad English

hi

nice thread .

so i unlocked my boot loader, ( xperia z3 dual ) and my phone powered on no problem, then before the rom could boot, i re flashed kitkat rom , it got flashed without errors , then the phone booted. in the middle of boot the phone restarted, and a very loud beep came out of my device, it got hot so i just force shut down it (power + vol up). after that phone doesnt react at all to anything, no led no power nothing nothing nothing... windows says usb device not recognisable when connecting it...

so im stuck with a dead device now like 3 hours in the wall plug but nothing happens... is there anyway to fix this??

Battery is over 90%

Pc detecting Semc flash device.

I can reset my device by pulling the battery out.

Hello everybody,actually i'm trying to fix my xu. Situation is :

- no flashmode / fastboot

- only red led

Help?
[Sony Cross-Device General] nageswarswain:
If u can then remove battery for few mins then reinsert the battery and try to enter to flashmode.or the rubber band trick.
[Sony Cross-Device General] Toledo_JAB:
Normally a red led is a sign of a type of low power charging that happens after a battery goes completely dead.

It should red led for a time then try to boot.

If there is a bad kernel it can try to boot then freeze until battery dies then red led again.

The trick is to catch the phone when red led goes out But BEFORE it tries to boot.

This is how the rubber band trick works ;)

Lots of good info about battery cycles and more in the first post.

However a red led can also mean a hardware failure.

Out of ideas...

Well, I'm out of ideas. I usually manage to figure everything out by reading, but this time, I'm out of my league. I was trying to repartition my Xperia S, bue something went wrong, and no more internalSDcard, etc. So I went to flash the original ftf file to restore the partitions, but I simply can't get it to work. My bootloader is unlocked, but it does this error everytime (see below). I tried locking the bootloader, and tried to repair via pc companion, but no option shows, just some tutorial on how to reset the device. Afterwards, I unlocked the bootloader again. I'm running windows 8.1 I've tried rebooting to install the unsigned drivers of flashtool. All of them are installed. I can still access TWRP. When I press power, a green led shows, vibration, sony logo, and gets stuck. I'm apparently able to connect via fastboot and flashboot, but I can't get anything to work. Can you give me a hand here? :(

---------- Post added at 08:30 PM ---------- Previous post was at 07:41 PM ----------

Also, if the phone is inside TWRP connected to charger...is it actually charging?
[Sony Cross-Device General] Toledo_JAB:
I think you can try to flash a stock system image using fastboot.

You may need to create the files by converting a stock ftf file into the .sin file set.

I am pretty sure that flashtool can do this conversion but I am not sure on proper steps. Google should help with instructions.

I think that you need to flash the system partition to restore the SD partition. The internal memory partion for the SD card is normally located in the /system forlder. So flashing a new system should get you the proper partitions back.

Flashtool may be finding an un-partitoned area and giving error.

Setting the flashtool log level to debug will give a better output for troubleshooting.

But fastboot should flash regardless of existing partitions.

With the phone booting the kernel and getting to TWRP it should be able to charge.

But the phone may need to be off first.

With phone off, plug in charger should boot into kernel charging with onscreen battery icon.

I am not sure if TWRP has a charging feature.

Since you have a good working kernel you should be able to recover the system.

Just takes lots of reading and trial and error.

If nothing works then try flashing a stock ftf file using flashmode (green led) with the log level changed. It should output a few pages of log you can copy and paste. Then post it here.

This may give more helpful information.

EDIT: does TWRP work for formatting the system or sdcard? May need to change the "use rf- to format" so that it uses the rf option

If this works then try flashtool and ftf file.

Guys, I'm having an Xperia M2 which just died while watching a YouTube video. (It froze).

Now it's just completely dead. No red led...nothing at all. I tried unplugging the battery from the mainboard for a few minutes, but the led still doesn't light up in any color when I plug it on a wall charger. Any ideas?

If i connect it to a PC, windows sees it as a SOMC Flash Device. That's all.
