Sony Ericsson Xperia LT18i no flashmode, no fastboot and stuck on logo - Android Q&A, Help & Troubleshooting

Hello friends, i have a problem with an old Sony LT18i from a cousin, he brought it to me because he has the China Mobile variant with no GApps and android version was 2.3.4, i thought it might be solved with a simple flash via FLashtool, but when i've completed the downloading of the ftf file and went to flashtool to flash it, when the flashtool ask me to put it in flashmode pressing the back button and connecting to usb the phone led only blinks of 0.5 sec and then boots into normal mode.
Tried the same with fastboot and then i got the same blink for 0.5s with no detection at all. That surprised me as well i've have flashed succesfully other Xperia devices with no problems of led blinks at all. Now my problem is that later i tried to root the phone and installing CWM to flash another ROM or GApps package, and when i finished to install the recovery now the phone is bootlooping and never gets to boot normally.
I've tried with 4SE dongle to flash it via Testpoint and it doesn't work as the phone manufacture model is 12W13 (new security) which the dongle doesn't support, tried with S1 Tool with version 28II215 and 080714 and i only get PHONE NOT SUPPORTED IN THIS MODE when i try to flash and when trying to unlock the bootloader it gives me NOT SUPPORTED MCU REVISION.
The phone was working well until the CWM installation except for the flashmode and fastboot mode, now i really need to flash it and i can't find a way to do it, i also have RIFF JTAG and Z3X Easy JTAG box but no JTAG available for this model except for Medusa Box which only supports phones with manufacture date less than 12W10, i was wondering if thereĀ“s a way to access via QHUSB_DLOAD mode doing the testpoint to manually flash partitions to device or something like that. If you might have a workaround or a solution to at least let the phone in the way it was it will help me a lot. Thanks in advance, sorry if my english isn't so great.

sorry if i made any mistakes im new to this forum
it just shows the sony ericsson logo
have you tried pc companion and update service it may get your phone working.
yes but it says i have to activate the usb on it to connect/use it with pc companion. and as i doesnt boot, i cant do this.
Have you tried se update service as you say your phone is not booting.
If update service can't do the magic then you will have to go for flashing tool ....
i cant get into flashmode (when the green led is on). so update service and pc companion dont detect it
now use flashtool and follow all the instruction on this link below

HElp Help Help!!!!
Ok. Judging by the fact that you're stuck on the Sony Ericsson logo, I'm assuming you're on the stock kernel and also on locked bootloader. Because you tried to install BlackHD Edition as well, I'm assuming you also have CWM.
The simplest method is if you made a backup in recovery and can access recovery. If you did this, you can simply restore the backup to get the ROM and data you were using before back. If this does not work properly (sometimes backups are screwed up somehow in recoveries), read on for the flashing method.
The X10 showed a green LED when you plugged it in which suggests that it can access flash mode (which is what I'd expect if you didn't tamper with the X10 so much as to break even that). If you have FlashTool, the following series of instructions should work:
1. Download the Xperia X10 stock firmware and move them to the firmware folder of the X10 FlashTool (the firmware can be found in this thread as well as the latest FlashTool: http://forum.xda-developers.com/showthread.php?t=920746)
2. Open FlashTool and press the flash button at the top left of the program
3. Select the stock firmware from the list and press ok
4. Instructions telling you to turn off and unplug your phone and plug it in with flash mode should pop up (hold back while plugging the cable in). Follow them and wait.
If you did this properly, you should have flashed the stock Sony Ericsson firmware with everything as it was when you bought the phone (if you flashed the 1.6 firmware) or updated the X10 to 2.3.3 (if you flashed the 2.3.3 firmware). That should be the most fail-proof and reliable way (I've saved my X10 from my stupid experiments through this several times already)
Just a little side note: If my assumptions are correct, you tried to flash the BlackHD Edition MIUI-based ROM through CWM on a locked bootloader and stock Sony Ericsson kernel probably without flashing the lockedbl.zip that's provided in the BlackHD Edition thread. Most FXP custom kernels work with that ROM without a problem, but the stock one just doesn't because it's far too different. You could have either chosen the locked or unlocked installation method on the thread (I know because I've done it before). The unlocked one requires an unlocked bootloader and a FXP custom kernel, neither of which I think you have. The locked method only requires CWM installation and for you to flash the lockedbl.zip after installation. I think your issue must have come from the fact that you forgot that last part, or some other strange error occured.

yours assumptions are correct.
About instructions to how to connect to flashtool, i know they. i click on flash button, select firmware and when pop up to plug-in, i do it...but don't work...don't connect...
As in, it doesn't recognise the device?
I think there's another way where you take the battery out and plug the phone into the computer. The green LED should light up for about 5-10 seconds (when it's in flash mode) where you have a window to select the firmware and flash. I haven't personally tried it, but I'm asking someone who has done it about how it's done. You might want to try that method as you can't really do much else with your phone right now. I'll update this post once I know the exact method and details

thanks a lot
anything news? please i need help!!!!!!
Once flashtool asks you to connect USB cable..connect the phone with the battery removed. THEN replace the battery while holding the power button and it should start up into flashmode.
It may even work without holding the power button...
Its strange because when stuck at SE logo you can't follow the on screen directions to get it to work

If your bootloader is locked, you can choose the option to repair phone in pc comp. Another possibility why your phone is not detected might be because of drivers.
It may also because of his usb not working , the problem might have started . I want to check out whether your phone is charging and i also want to know that in devicemanager your phone when connected in flash mode shows as "semc usb device "
Thanks

Try This Once..Worked For Me

Rooting failure

Hi, so..here's the problem. I've tried to flash my tablet with a 307 firmware, mine was 253.
now i downloaded Flashtool, Downloaded the firmware. done everything the way it meant to be.
and then in the middle of the execution it said something about failure and stopped.
now my tablet won't boot.
When ever i try to boot it, it just shows the Sony logo and dies.
and when i hold the volume down and connect USB the green led light is there just for a split second.
but the volume up and connecting USB shows the blue with no issues.
any chance anyone can help me ?
Edit : I Understand now that those things are normal. the problem is that no software would recognize that the device is in flash mode or fast boot mode.
With that I do need help.-
Edit : What? that's it? I can throw it out of the window or what?
Nothing?
Anyone?
It's been few days..
have you unlocked the bootloader to do your root or did you just go straight ahead to root your XTZ? either way is fine as the root tool kit by doomlord works both ways.
make sure your tablet is charged. did you use the flash tool by bin4ry and androxyde? you can also download sony software emma (if you've unlocked your bootloader)which will restore your tablet to manafacturer default. or just use sony pc companion software if you havent unlocked the bootloader this will work too.
the fact that the sony logo still appears on your tab at least shows its not bricked, ive had my fair share of thinking i'd bricked my tablet but if you've done your research you'll find you can get it back to working order.

[bricked] Can't get back to stock

Xperia MINI ST15i
I have exhausted every method I can find. Fastboot seems to be broken. Fastboot and Flashtool both do not detect the device when it shows BlueLED(fastboot). PC Companion doesn't detect at all.
Flash Mode seems to be working. It seemed like it was flashing, progress bar and everything. When it was done it said for FLASHTOOL, the phone has to have usb debugging and unknown sources checked. Being that I am bricked, there is no proper system installed .
In FLASHTOOL & EMMA unlock bootloader doesn't work. I got the code for it to do in FASTBOOT or keypad but neither are accessible.
I believe I flashed a recovery for the wrong xperia model =/
Are there any other potential solutions?

[Phone bricked] need help

So my mothers xperia z5 compact have gone totaly bricked after making a software update and i can't find a way to fix it in anymay. It bootloops and after the white sony logo it shows a dead android with the message "Fel" (Wrong in swedish) and and just continue in a cirle like that. I can't seem to get into either recovery or fastboot tried with adb/fastboot with the computer still can't acces it, neither sony companion recognice it. Anyone can maybe have a solution will make a big help here because i'm totaly out of ideas to fix this.
This will remove all data, except SD card.
Requires Windows and a 2.6GB download.
Search for flash-tool-for-xperia-devices download Sony''s website and install, will install as Emma
Hold volume down and insert a USB that is already connected to your pc, release when power LED turns green
In Emma chose an service and click Apply Service
This will download and install it to the phone.
Download flash tool and download the proper tft using xperifirm then flash it.... http://www.flashtool.net/downloads.php
If you search the forum you can definitely find a guide on how to use the program.
I also bricked my phone. Tried flashing a generic TFT in Flashmode via the Flashtool, and it seemed to go through.
But now, it shows "Update failed, please connect your computer" logo when I try to boot it.
I had previous tried mucking around in fastboot mode trying to flash Lineage.
I may have accidentally messed up my boot.img. If so, which one will I need to flash, and how to go about doing it?
