[Q] Xperia Neo <not working>

I have xperia Neo update with ver 2.3.3 As i come out of my mind to think to root my Neo without unlock the bootloader. unfortunately is being a mess for me right now.
I try to follow the instruction from this link
http://forum.xda-developers.com/showthread.php?t=1115542,that
where i try to first step flash the firmware to the phone.
However, after flashing. as i power on the phone to do the first rebooting, it make me wait up to 20 min, and suddenly my phone make a continuous beep sound, and then leave a blank screen with no respond.
currently i have no idea to make my phone comeback. i try to reflash back with generic firmware "mt15i_3.0.1.a.0.145_GLOBAL.ftf" again with flashloader.
I try to press the back button to insert the USB to bein the flashing, but the pc can't detech the phone at all.
Is there anyone can help me through with this?

is your phone fully charged ?
when the battery is under 30 % or so, it won't go into flash mode ( had this problem with my ARC )

thanks for the reply, my phone back to original already

i wonder since the xda developer don have xperia neo section exist
in case there is new ROM or way to handle the phone.
where should we post it?
I just worry not much ppl gonna look through on the custom firmware and how to root the phone without unlock the bootloader

have u unlock ur bootloader? tell me your details how u make it

yes i unlock my bootloader,but now PC companion and SEUS is updating with my phone before its not due to modified software

root error - aborted. now arc won't start anymore, nor flash. help me plz

I was trying to root my xperia arc.
i started flashtool, everything went alright. then error -aborted.
now phone can't start anymore, I can't do anything with it.
plz help me

You have to tell a little more to get the right help.
Bootloader locker or unlocked?
What firmware did you use when rooting the device?
What did you use to root, Gingerbreak?

i'm sorry
bootloader locked, never touched that
i never touched anything. I'm on 2.3.3, so I was trying to get back to rootable version.
its when i was trying to flash it to previous version that flashtool aborted. saying : power on go to settings and turn on ressources and debugging.
but i can't do anything with. It doesn't even start up.
thx

no prob, can imagine you're upset
did you try to flash it again?
How was your battery when starting in the first place?
Did you try to start up with power cable plugged in?

wow i just tried sony ericsson update service, and now the phone seems to start up.
the mistake i did i think is that i forgot to reinstall the sd card before starting to flash it.
as i'm writing this the phone is correctly working. so now was the sd card remove the mistake ?

1st option
I would say unlock the bootloader and reflash with the newest firmware, or you could just try this
2nd option
http://forum.xda-developers.com/showthread.php?t=1126358
I had the same problem (but my boot loader was unlocked) and it sorted it out, I thought it was just flashtool but it isnt theres special files in the firmware folder that unbrick the arc, let us know how you get on. try the 2nd option first
If its working now then it was a semi brick, option 2 fixes them no problem, try reflashing if you get the same problem just use the 2nd option afterwards and it will work fine

@grat_master
dunno bout the sd card, but glad SEUS did the trick for you.
@yusuo
can you unlock your bootloader when the device won't even start?
anyways, things worked out, no need to do more i think

ok so now the phone is working correctly.
but i tried it a second time to flash with flashtool, and it did the same thing. flash aborted, power on go to settings and turn on ressources and debugging.
what am i doing wrong ? i'm following namaste guide http://forum.xda-developers.com/showthread.php?t=1133650
but it just doesn't work.

yes you can, you put it in fast boot mode (turn phone off, then hold back button and plug usb in while still holding back button)
If is still doesnt turn on after use the brick fix (option 2)

Seemingly others have had problems too..
Common reasons:
http://forum.xda-developers.com/showthread.php?t=1162492&page=2
And try running flashtool as administrator and make sure you have the lt15.sin in loaders directory..
Unlocking bootloader is good if you want to install a custom ROM.. But u void your warranty and loose DRM (If you care bout those that is..)

LT15.sin is already in loader directory
and I'm also running it as admin, I also disabled user control.

Which firmware are you trying to flash, the UK or HK version? Maybe it's a corrupt file?

i live in canada, and i'm using a rogers branded phone, samething as in the video of namaste guide.
i am trying to flash north america generic and world generic, neither worked.

Have you tried removing the battery after flashing, and then putting it back and then boot up?
Sent from my LT15i

it can't flash !
i am not able to flash anything, it stops before end and the phone remains in flash mode even if I deconnect usb cable. I can connect it back to pc without pressing back button and the green light is on again. that's after the flashing crash.
now the phone is ok, I can go internet, receive give calls, but I still have my sms problem that I have since beginning. I'm sending it back again to sony for repairs. HAHA I received it from repairs yesterday, and I got exactly same problem as before. I hope they change it. I think my phone is broken /end of story. Broken from beginning.
Anyway, I'm heading back to my Rogers detailer now to see what they can do again.
Thx for help. I'll try to root again when I get it back.

Okay, good luck, hope you get a replacement!

my service provider Rogers Canada is sending me a new Xperia Arc, should receive it in 3-4 days. As soon as I receive it, I'm gonna try root.
I'll let you know if it's working or not.

ok so i received my new xperia arc. now my sms problems are solved ! hourra
but i still can't flash it to root. It just don't want to do it.
what am I doing wrong ? I'll try a new ftf file. Can it be related to a bad sd card ?

Please Help me! Stuck in fastboot!

Hey guys, earlier I managed to sucessfully unlock the bootloaders and thought i might try to install one of DoomLords Kernals, the Kernal initially loaded and I went to install the wifi module zip. Afer I did that, I tried to reboot but the phone was not rebooting so I thought instead I would try to relock the bootloader anyway. I happened to have installed one img file from a video on Youtube regarding the Xperia S.
I think I might have installed the wrong img file and now I and now I can only enter the fastboot. Whatever I do i cannot get back into the system. I flashed a generic stock rom 2.3.4 just incase I had lost the system files, once I connect the phone to the computer the PC Companion seems to recognise the phone but I do not see anything?
What have I done wrong here and how do I fix this problem!!?!
Help will be well appriciated! Thanks!
PS: Sony Update Service says " The phone has modified software that cannot be updated ".

"What have I done wrong"??
U CAN'T randomly pick IMG files and flash like this buddy...you're lucky u don't have a brick.
Now I suggest you download the update manager from Sony and connect your phone go back to stock. Forget root, forget unlocked boot loaders..

Flash an ftf file, tutorials are everywere, and to relock the bootloader for our device you have to flash another ftf file somewere.

The method hasnt worked.... the phone still does not switch on.... here is the log data from flashtool...

Have u tried Sony's update manager??

It seems that my only prolem now is that whenever i need to restart or switch on my phone, i need to remove the battery and put it back in. It seems to reboot quite often.

If u are back on a running phone, format the system once from CMW...& a stock ROM from Sony will solve all ur problems...

Why is this is the development section? Xda has rules for a reason, and you need to follow them. Moderator please move this to Q&A.

[Q] I think i bricked my Arc, flashtool always gets stuck!

So my phone was running perfectly until i decided to sell it, unfortunately the sales man wouldn't accept my Xperia arc because i had AOKP, i opened recovery mode, choose restore, and i selected an old back up to restore, i thought it would bring my phone to stock.
But then whenever i turned my phone on it would crash with the AOKP start animation half blank, like the bottom half of the screen is completely black.
I googled "my xperia phone is bricked" and i heard that i can flash stock ftf to restore the phone, unfortunately flashtool gets stuck at around 8-13% percent every time.
I tried MANY different versions, many stock roms, turned off my anti virus, changed the cable, booted into safe mode with networking, it still lags. :crying::crying::crying:
Now whenever i boot it up it shows a phone with a warning sign next to it
I looked these forums up and someone suggested that i relock my bootloader and try the Sony update tool, i tried it but it says phone is already up to date
Now my phone is dead, battery ran out and it doesn't show the battery animation when i charge it, does that mean it's not charging?
Please help me, i just want to flash a stock rom and unroot it so i can sell it.

Use PC Companion's Support Center (if I am not mistaken) to repair your phone's firmware.

PC companion keeps saying i should turn on my phone, i can't turn it on.
I flashed KTG kernel and now the warning sign doesn't appear, only the Sony logo, whenever i try to turn the phone on it just shows the Sony logo and freezes, i tried to get into recovery but i can't, the led doesn't flash so i can enter recovery.
Thanks though.

Choose the option that you can not start up your device/repair your phone. It does not require you to turn on your phone.

YES, it's working again, thank you very much!!!
I "repaired" with PC companion and it wouldn't start, it still lags at the Sony logo, but after repairing it with the pc companion i was able to flash stock ftf without any problem, it's very weird flashtool always lagged before, i think it's because i repaired it now, or maybe because i charged my phone over the entire night? can a low battery cause flashtool to lag?
Anyway that doesn't matter now, thanks again.
My phone is working again after flashing generic world stock ROM, now only thing remains, how do i unroot and relock the bootloader? or is it unrooted already since i flashed a stock ROM? :\
I just want to sell the phone but unfortunately rooted phones don't sell here, every salesman i met rejected me, i want to unroot the phone and relock the bootloader, i just want to make it look like a brand new phone, it's in an excellent condition hardware wise.
I heard factory reset would brick my phone so I will wait until the phone is done booting up and i will download root check and see, i will also check if the bootloader is locked or not from the service menu, after that i will update this post. :good:
EDIT 1: Okay this is very awkward, my phone's battery is completely empty, i have no idea why it's at 0% even though i charged it over the entire night???
Anyway once it's done charging i will check the root and bootloader condition.
Sorry for my bad English.

If you flashed stock firmware, then root is already gone.
And if PC Companion installed firmware to your phone, then bootloader is locked, otherwise PC Companion would have not worked.
If you are still sure, that bootloader is unlocked, check the tutorial in my signature, it includes information how to relock bootloader.

Is there is still hope to make it live back?
I really love That phone . I really love it .
pls help me

As i see it, your bootloader is locked, you have (had) recovery for locked bootloader and you tried to flash custom rom and custom kernel. "it won't work" is short description, long description is your entire first post.
You have two options:
A) Unlock your bootloader and try flash kernel and rom again (you didn't say what model you have, so it might not be even possible)
B) flash stock firmware (ftf) with flashtool or even better, use pc companion to get your phone back to life

You can find a ton of stuff here ^^
So find your stock ftf file (depending on what version of phone you have) and flash it via flashtool. Hopefully you still can. Give Google a shot if you need instructions.
Or go here -> http://forum.xda-developers.com/showthread.php?t=2054486
PLEASE USE THE PROPER FIRMWARE FOR YOUR PHONE. You may cause irreparable damage to your phone if you flash the wrong firmware.
Sorry for the all caps, but I just want to make sure that I helped and didn't cause any more issues. Best of luck for you.
