[Sony Xperia Miro, Tipo (Dual), J, E] xperiajproblem:
Hi all,

I will be eternally grateful for your help but I am not holding much hope.

I got this new phone from my operator Three in the UK back in January this year.

All works ok except for the screen calibration which I did not get round to fix.

On Monday I decided to put a pin lock on my phone, as I haven't been using

the pin lock for a few years now. I chose the pin code, then I stupidly tried

"Lock Sim". Then the screen came up with sim locked, PUK needed.

I did not make even one attempt with the PUK code as I decided to phone

my operator for it. We went through the procedure, he gave me the PUK

code and we managed to unlock the sim card and then I remember the

pin code (as I always have) and inputted it and the phone is unpinned.

I need to mention that we did have one or two bad attempts where

I couldn't hear the technical guy too well and I did enter the wrong pin

once or twice, but less than the 3 attempts limit and we did have to

take the battery out 3-4 times due to this and also because

I kept putting the sim card the wrong way round being very careless.

The sim is unlocked but on the screen it is "no service" emergency

calls only, where if you choose the emergency option green button

it will give you a menu and * # . I can see some symbols on the top

such as wifi connected. If I call this mobile phone I can pick up

the call, the screen has the usual answer or reject phone symbol on.

But during and after the call pressing the home/back/menu button

on the phone (off the screen ) have no effect. I told the technical

guy about this. He suggested a new sim but if I put my old sim

in my other three pre-smartphones phones it works. However

this phone is tied to this sim card/phone number only as I try

my other sims on it and they do not work.

I have tried a few things:

the 7378423 thing with all the right *#, doesn't work. but 06 works to get IMEI

cannot enter fastboot mode holding down the volume up button and plugging

USB in, but can enter flash mode.

I do not want to lose data as I have some important data which I haven't

backup to my sin so I don't want to use PCC or SUS to install either

the current OS (I think it is ICE cream 4.04 ish) or the new jelly bean.

To complicate matters my phone is not USB debugged enabled so I

cannot use software to do a quick backup of my phone I tried

mobile me from wonderware(?) and its needs usb debugging.

PC companion doesn't have restore and backup anymore, or at least

not for xperia J as the Sony support guy told me, if it does it probably

needs debugging enabled.

Talked to Sony support, he said the only way is to use PCC to reinstall

software and I will lose data as expected. I asked him if Experia J

and the newer Xperia phones have disabled the 7378432 service

code and if there is a new one which he can tell me. He says there

are no new codes.

The phone is not totally now working, I managed to get into "safe mode".

I wonder if the phone actually is rooted or has bootloader unlocked I

read if that is the case it may explain why the 7378432 does not work

as it only works on sony stock rom. But then I came across other people

whose phones may not be bootloader unlocked and this code does not work.

I also came across people who cannot get into fastboot mode.

Maybe because my batch of xperia J, together with customisation by

my phone operator has disabled 7378432 and fastboot which I don't thin

so as Sony themselves mentioned the use of these two important

elements in their unofficial but be warned section on unlocking the

bootloader. I wonder when I took out the battery a few times when

I spoke to the technical guy my phone is locked due to security but

as I said before the PUK code was entered correctly first time round

if not second time round, so is the pin, We just took the battery out

and retried about 2 times as my sim was in the wrong way round.

Finally my apologies for the long post, the phone still has my wallpaper

on it and the error message I used to get from an app (telling me the

app is not working) when I turned on the phone. If the phone was

flashed/rooted then it was not done by me, it might have been done

by a previous owner and then returned to the operator within 14 days

and then my supposedly new phone is this rooted phone. Without

usb debugging enabled its hard to go into recovery mode via

usb link/flashrom/boot etc? But if we know which rom we can

try to go into recovery mode without a usb link by pressing a few buttons?

At the end if I have enough money which I don't sadly someone at sony

can probably take the phone out and do some high level fixing, as long

as the memory is still in tact which I hope it is. For some reason the

phone is locked in this emergency calls only mode. I have not made

any attempts to root it etc before Monday and no attempts to root it.

I just thought the 7378432 can "unlock" a phone lock like the much

discussed xperia Z - if the phone is on a pin/pattern lock etc.

My attempt to go into fastboot mode is to hope that by getting in

and getting out of it the phone will reverse back to normal. My situation

is mainly complicated by that I really want not to lose the data, sms

particularly when we try to unlock/unfreeze the phone.

Extremely sorry for the long post, if anyone can help I will be

most most grateful, bye for now.
