Phone vibrates on startup. After all these tries, my phone, on boot-up show nothing just black screen and the green led blink 2 times. Please help, thank you !

[Q] Xperia x10i wont boot after root atempt

Hi,
Last night, i tried to root my Xperia x10i phone, following the steps in this article:
http://forum.xda-developers.com/showthread.php?t=711907
After completing the 1st step, i tried to boot my phone. I get the usual vibration when booting, and after a second or two, the phone had started vibrating endlessly.
Then i tried to recover it using PC Companion (Connected in flash mode). It downloaded the firmware and installed it to the phone flawlessly.
I disconnected the phone, in switch on. Get the usual vibration, and then the screen backlight starts to turn on and off constantly. As the PC Companion says this could happens for a few minutes at first boot after update, i waited, but it simply remains doing the same thing, and never show the SE logo.
I tried to repair again, this time using SEUS, following all the instruction, with same result.
I dont know what else can i do... Please Help!!!

You mean try to flash it to 2.1? Or to 1.6?
flash it to 2.1
Ok. I've just tried to flash with a 2.1 x10i generic rom and a 2.3 x10i generic rom, following the steps in the video. Dont work...
hmm.. weird, any1 can help here?
Yesterday, i left the phone in the office, with the battery out, hoping that something i read in a forum, about this could work, was true. Today i take the phone, put the battery back, and turn on the phone, and... No luck... My xperia is still dead...
Try using SEUS instead of PC Companion.
Follow the instructions ins SEUS and make sure that the phone is off and hold down the BACK button before you plug in the USB cable and make sure you keep it pressed down until the software tells you otherwise.
I've done so, but still dont work... But i'll try again...
I've just tried with SEUS, which download the 2.3 update. SEUS run all the way, and says disconect and turn on. Same result...
Any sugestion?? I almost give up on this... =(
I have the same problem, i have tried to flash my phone like 30 times i have bought a new battery and still no go, it continuasly vibrates.

Use pc companion to repair phone.
Sent from my X10i using XDA Premium App
I tried to update my phone (2.3) with PC companion, it worked well until the end but i had an error message, I tried a second time but the same, and now I have a warning logo immediately after the sony ericsson logo :
When I connect my phone to my computer, it boots and I have the same logo, and it reboots, I tried to press the return button and it didn't work...
And I can't access to the repair function of PC Companion.
I hope you can help me...

Thats exactly what i did too everytime i brick my Xrecovery.
SEUS..
I tried all those softwares (PC Companion, SEUS, FlashTool) and nothing worked...
With SEUS and FlashTool, It seems to work, but in the end, I have an error message. With FlashTool the installation aborted and with SEUS a failure.
Could it be the battery? (I can't charge my phone...)
Try and diconnect the battery for a few minutes and plug the charger in again and leave it for a few hours.
If you take the back cover off there is a small rubber cover that can be carefully takem loose and beneath that cover you see a white plug and that is the batteryconnection to the phone.
I´ve bricked mine so many times now that I just leave that rubber cover off...

[Q] Xperia Neo won't start

Hi. My xperia Neo crashed, I tried to send a photo via bluetooth and the phone just turned off. I tried to turn it on, it appears the "SONY" screen, then the "XPERIA" screen, and then it restarts, over and over again with the same 2 screens. I searched topics, they say that I have to flash it, but I can't start the phone in flash mode, with power and back buttons, any software (Companion, flashtool) don't detect the phone. Is there any solution?
Just like death

Hi, I´ve got similar problem. A year ago my Neo V went dead (I thought so). Just for fun, I tried to connect it to PC yesterday and what happened? It started charging and after few minutes I started it (YAAAY)! So I thought It was just some bug that disapiered after discharging. So I did a hard reset, to gain factory settings, repair the firmware via PCcompanion, everything was OK until I shove a memory card inside. After that it died again. Its not charging, no reaction after connecting to PC, no reaction on ON/OFF button, no reaction for button-hard-reset, no response while trying flashing with EMMA or FLASHTOOL, nothing... Does anybody knows what to do with it or do I have to wait again until it discharge and pray it would work after that?
help
I have the same problem as you did it to solve? :crying:

Xperia Z2 keeps bricking no matter rom or kernel

2 months ago I unlocked the bootloader and flashed a rom, everything went fine until 1 month ago when it stopped without a reason. Restart using the red button because nothing else worked, repaired it with the Xperia companion. after that it kept hard shutting down and it won't respond to the red button in the first tries to restart(10 mins of pressing the red button), I have to try multiple times to boots back. it workes for a day or so if i flash any rom but then it hard shuts down again and i have to flash a rom again. Any ideas?
edit: i might add that i used flashtool and when it hard shuts down fastboot or anything wont work
Clean flash a stock rom using flashtool v0.9.18.6
