Or relock bootloader
Help please
Sent from my LT18i using XDA

use flashtool.flash new firmware..n you can relock bootloader...

When you change to ics the pc should automatically download new drivers. Try connecting in msc first, then disconnect and try mtp

nothing
no flash mode, fastboot, mtp and msc mode

download acronium 7.2..use card reader n put to mmc..update using recovery...try it

thanks
before flash arconium
i wait a reply from http://unlock-bootloader.com/
Trim Area (GDFS/EEPROM) is the most important part of the software on the Smartphone. If your device doesn't turn or even if PC doesn't detect it for flashing, this service is what you need. Also works for fix IMEI problems when you can't get signal.
wait & see

Hey, seems yes maybe its a problem with trim area. We can fix it.
But since the phone boots in recovery first i think is a good idea to try to flash a different rom to see if something changes.
Anyway i will send you more info to your email.

my pc wont recognize the phone.. i think i need to charge it for far longer time to have it the first cycle as the guide for recovering a bricked xperia device.. thanks for your reply sir..

2 hours is enough. At some point it will try to boot. Then put it in flashmode and flash with Flashtool the ROM. Do not try to power it on. Wait,it will try to boot by himself.
Don't charge him from pc. Use wall socket.

Cant Get To FastBoot or Flash Mode

I recently flashed CM9 to my phone, but now i want to move on to JB, but for some reason i can not get into flash mode to write a different FTF.
When i I try to get into flash mode, I power the device off, hold the back button, and insert the USB cable. The LED on top flickers green then the screen comes on the the charging screen.
The same happens when I try to use fastboot except blue light flickers.
I have tried diferent computers, cables and OS's im not sure what else to try.

Download flashtool and install the drivers for your phone then leave your phone and enable unknown sources and enable usb debugging then open flashtool then press flash icon and select fastboot mode then plug your phone in then select reboot into fastboot mode via adb

I ran the driver utility and even when I send reboot bootloader via adb, the LED only flickers blue for a moment, then it boots to CWM.
I didn't think the drivers on the computer would change if the phone goes into flash mode or not though.

Default Cant Get To FastBoot or Flash Mode
You would need to be in flashmode (green light) to install a stock FTF not fastboot mode has suggested above. Have you tried flashing another version of CM9 with your phone via cwm and then trying from there see if the problem is not your rom.If not it could be a driver issue.

I know i need to be in flash mode, i just reinstalled cm9.1.0 and it still has the same problem. I dont know what to do. I have tried multiple cords, I have used ubuntu ,win7 and win8 with the drivers installed and reinstalled. Im worried that my phone is broken.

(1) Have you installed other roms before your problem started did this only start after installing CM9
(2) Have you flashed any other kernels before CM9 or was CM9 your first rom/kernel flash
Noticed on your first post you wrote that you hold the back button then attached the usb did you do this when flashtool said or before, you need to connect the usb exactly when flashtool tells you to like below step 5
(1) How to flash a stock .ftf Rom
(2) load & place .ftf rom in Windows/flashtool/firmware folder
(3) Open flashtool press lightening icon press flashmode
(4) Select your .ftf you placed in flashtool /firmware folder earlier
(5) Wait! Flashtool will tell you to connect your phone!
(6) Press & hold back button while connecting phone to PC green light will come on.
(7) Wait while flashtool starts flashing your stock rom.When finished it will tell you to reboot
(8) Finished unplug switch your phone on done!
Sorry if you already do it like this but some people forget and connect the usb too early Also I would recommend downloading a different version of flashtool some people have managed to get there phone working by using a older version of flashtool:good:

(1) yes, i have installed several roms before CM9 and i was always able to enter flash mode.
(2)I have tried doom kernel and several other kernels as well
I have waited till flash tool prompts, but IIRC id didn't matter in the past, flashtool would see what mode it was in and proceed.
Thank you for the descriptive reply.

Did you try a older version of flashtool http://androxyde.github.io/index.html?1375894152000

I just tried versions 7 and 8, it doesn't seem to help.
I feel like this is something wrong with my phone though, I remember the phone being able to go into fast boot and flash mode at any time, as long as the computer was on. It is really weird how it flashes the color on the LED.

I so this quote on another thread similar problem to yours this is what he did:
Quote: Funny thing though is that in order to get into either mode, I have to remove the battery while it is plugged in and then hold down the corresponding key while inserting the battery and the corresponding light will then light up. That seems to be the only way to get into the modes. And sometimes this does't work, but it seems to work more than not.
This guy did this to get into fastboot and flashmode worth a try?

no luck... The light only blinks then goes into charging mode...
Edit:Is there a test point or something that would force the phone into one of these modes?

I read this for another phone and it is a shot in the dark, but if the boot block were zeroed out, it forces it into fastboot. If this can possibly work, what block device is the boot partition?
I will not bee too disappointed if the phone is bricked.

Hi guys!
I have Sony Xperia Arc S.
Is it possible to put it in a Flashmode without a "Back" button? My BackButton is broken, I think it is a road-wire on the button's board.
BTW Fastboot mode working fine.

Root with New Kitkat Update!

The old root process will work with newer Kitkat Update on our Ultra Dual? Or somebody needs to create the new one for kitkat?

towelroot not
towelroot no working em xperia T2 dual

Towelroot works fine in T2 Ultra Dual.
First install SuperSU from Play Store
Enable USB Debbuging
And then follow towelroot steps.
And if you get stuck in a 'Clean' message on the prompt,just disable and enable USB Debbuging without disconnecting your phone.
It works for me. Try it for your own risks.
Sorry for bad english.

What version do u have?...If its 4.4.2 then u must try EasyRoot Toolkit. It works like charm.

The only method that worked was this:
In the 19.1.1.C.0.56
1. flash 4.4.2 stock kernel
2. root by Easyroot tool
3. flash 4.4.3 stock kernel
4. Install recovery
5. Flash Supersu on Recovery

If you have the ftf file,just flash it with flashtool but exclude everything except kernel...that will do

select all options except the kernel and uncheck data. After giving Flash the kernel 4.4.2, the screen will turn black, so this leaves the USB enabled before the deputation process. After restart, wait for 10 minutes and do the root.

Here is what to do in order to get your T2 Ultra Dual rooted:-
Assuming you are on stock KitKat 4.4.3 ROM. First thing you need to do is.. You need to enable USB debugging and Installation from Unknown Sources....Accept your computer on the phone screen if it prompts to do so...check these thinigs before u flash the 4.4.2 kernel cuz afer flashing it u will endup with a Black screen and wont be able to do the changes.
1) Flash the 4.4.2 kernel with Flashtool.
After flashing is done ...reboot your phone.....your phone will boot with a black screen on....you would be able to hear the boot up sound tho and the touch sounds as well when u press the volume rockers. Wait for the phone to boot properly with the black screen for about 5-10 minutes and then move for step 2.
2) Root your phone.
While its with a black screen but u have already enabled USB debugging and Installation from Unknown Sources ...You are good to go...Just plug the USB in and root your phone with Easyroot Toolkit....Move to step 3.
3) Finally Flash back the 4.4.3 Kernel.
Now this is the final step to get your monster rooted with 4.4.3. You need to flash back the 4.4.3 kernel so prepare ur Flashtool and wait untill it prompts you to connect the phone. The phone is with a black screen so there is no way you can normally shut it down with the soft keys. So this is what you are supposed to do. Connect the phone to the PC while its "Switched On" and press the "Volume Up" Button and the Power button together (Hard Reset) ...The phone will reboot...but here is the trick....You have to press the Volume Down Button before the phone vibrates and reboots. If the phone reboots..Flashtool will not detect it...So press the volume down button at the right time....right before it vibrates..If you can find another way to switch the phone off....that will be more easy....atleast i couldnt find a way lol.Once you successfully connect the phone to Flashtool it will flash back the new kernel and Voila!! You have Root with KitKat 4.4.3.
Show me your Love once You succed

thank you so much for your detail instructions, i will going to try again and back to you, i think i tried to root my phone while it was in black screen but it was not success anyway i will try it again..

Thanks for your explanation.
I'm still at rooted 4.4.2. Can you kindly share how I can install a rooted version 4.4.3? Thanks in advance

Bricked my phone

bought this cheap xperia z1 compact off a friend, never used a sony phone before so i thought rooting and installing custom firmware would be same as other android devices, the phone was running lolipop and i used kingroot to root it and then used flashify to install a custom kernel without knowing the device requires bootloader to be unlocked now my device wont turn on at all it vibrates 3 times and flashes red led if i press volume up +power button, i have been reading stuff online no solutions to my problem. tried flashtool but i cant get the device to recognised on the flashtool or get into recovery mode. which ever volume button i press and hold and try to power up it flashes 3 times red led. also tried volume up/down plugging into my laptop still red led. so can this device be unbricked or is it good as dead?

If bl is still locked, official Sony repair software might work, (but not sure if it will recognize that it was rooted and reject it). It's been a couple of years, but it used to be called PC Companion. You go to 'software update', and there's a 'repair phone' option.
Besides that, Flashtool is definitely your best bet. It takes a little setup, but not too bad - install Flashtool, and in the Flashtool folder is a 'drivers' folder, with a drivers.exe file. Run the exe and check boxes for 'fastboot', 'flashmode', and 'Rhine'. Let the drivers install, then connect phone in flash mode, (power off, hold volume down and plug it in). You should get 'installing device driver' popup. Click 'skip windows update check', and it will find the drivers already on computer from Flashtool. Now you need to download an ftf. Open Flashtool, and click the 'XF' button at the top. That opens Xperifirm. Find D5503, and click whatever regional fw you want. Now it will download and unpack. Whole thing takes about 10 minutes. When it's all done, open Flashtool, and select '' at the top, then choose 'flash mode', and navigate to the ftf file you downloaded. You need to double-click all the way down to the actual file and you will see all of the empty fields on the screen suddenly get filled in. If you want to go ahead and flash the whole thing, just click 'flash'; it takes about 10 minutes. Since you really only need the kernel, you can go to 'exclude' box and check everything except kernel files, then click 'flash', and it will be done in less than a minute.

Really appreciate for the information. But i just can't get flashtool or the pc companion detect the device. I don't know how to get it detected

Did you run drivers.exe and select the 3 checkboxes mentioned? Did it install successfully? If so, what happens when you plug in in flash mode?

Hey Levone. This bootloop thing has happened to me too. When i use flash mode, the led flashes green and then red, and nothing happens. I have my bootloader locked, and i flashed a new version of supersu, and got a bootloop. I lost my recovery, my OS, everything. I tried to get a stock firmware through xperifirm but that had a weird problem (some of the filenames were too long, so windows decided to not let me get that firmware). PC Companion does not recognize my phone. Could you help me?

Yes i installed driver.exe and checked those 3 you mentioned. When i connect my device holding volume down it does nothing. It shows on the flash tool device disconnected.

I think you're not powered off. Hard to tell with black screen. Try holding power and volume up for a few seconds, and see if you feel 3 vibrations. The you're powered off. Then try to connect in flash mode. Flashing a bad kernel shouldn't hurt your flash mode or fastboot.

Did you follow the drivers install instructions above? The green flash is a good sign, even if it doesn't stay lit. If you have the drivers, (and adb too, I think), you should get 'installing driver' message.

Yea, i got the "installing driver" message. It installed the driver "adb interface" or something like that. I don't remember what was it called, but something with adb in it. I will try using flash mode with flashtool, but i need a firmware. It would really help if you could get the ftf file from your phone and upload it to mediafire or somewhere where i can download it.

BTW - if you're going to go full ftf flash, might be a good idea to flash KK, which is easier to root, (doomlord toolkit), and then install recovery and flash LP prf. Otherwise, your either going to use Kingroot, or unlock bl.
