On ICS i was using 3G normally, then i upgraded to JB via Sony PC companion
i lost the 3G signal
i rooted the device using (Bin4ry_v28 tool), it's fine, no rooting problems at all.

OK
Find a ftf file for your phone (Probably one in the all in one thread) and flash it using flashtool. Just make sure your exclude everything except baseband. That will restore your phone radio settings

yes. Find flashtool in the first post in the dev section
Flash the ftf using flasdhtool. You will be given options to exclude certain bit of the file. Tick everything except baseband so that only the radio bit of the file is flashed
And welcome back from the dark side...iOS is like swearing here...

HIiii ..
i had troubles downloading the FTF file, so after some googling i decided to make my own 1.
1- i downloaded SUS
2- updated my phone
3- got the 3 update files from the file db
4- downloaded the latest Flashtool 0.9.10.1 from th official page
here comes a problem ..
there's no toolbox in this flash tool, so i wasn't able to decrype the files, i also couldn't fine LT29i in th devices list.
after some googling i downloaded th 0.9.10.2beta6 from this forum, which has a toolbox
1- i ran flashtool 0.9.10.2beta6
2- decrypt th files
3- created the FTF file
4- flash-mode
5- connected my xperia while pressing th volume key
6- phone connected in flash mode .... stuck here
7- nothing happened after that.
so i tried to flash it with 0.9.10.1
i just didn't have the option to exclude baseband from the list.
so :
1- i went back to 0.9.10.2beta6
2- i created a FTF file with baseband excluded from the hole file
3- i put the file in the 0.9.10.1 folders
4- i ran flashtool 0.9.10.1
5- flashed the phone
6- turned my phone on
8- every thing is OK BUT i still dnt have 3G coverage
can u help ?

Have you tried just a repair via PC Companion? Flashtool seems a bit long winded when PCC should do all this for you.

The problem is the file that pccompanion is downloading for you. It has the wrong baseband. That's why you need to get another ftf file for your phone.
If you create a ftf file from your pccompanion (Or SUES) download you will still be using the wrong files.
What was the issue with downloading the ftf file?

For flashtool, find it in the first post of the first thread in the dev section.

If PCC is downloading the wrong basband shouldnt it have killed the 3G on everyones TX who has updated to JB using PCC?
IMHO I feel that something went wrong at the time of update specific to this user and rerunning the process would fix it.

No, he already tried that.
It seems it is downloading a wrong ftf file because of a corrupt build.prop or some changes made prior to using pccompanion.
If you change the device name to something else it prompts pccompanion to download another set of files.
That's how people manage to download multiple ftf files for different regions and different operators. They change their build.prop.
This is the first step in a problem solving process and if it doesn't work it could be something else, but he has stated he has already tried repairing using pccompanion

Fair enough. I cant see the post were they stated they had already tried that. I was under the impression the build.prop hadnt been touched as they stated root wasnt available to them until after the upgrade. Also I would assume TX is TX it is not like T/TL if the wrong update was pushed via PCC the deivce would not boot at all.

Yeah, I just looked back through the thread, I may be getting mixed up, I have so many people I am currently helping on this forum and in PM....
@OP
Did you try to repair the phone using PCCompanion or SUES yet?

why are you excluding baseband...the whole point is to exclude everything EXCEPT baseband!
the baseband controls the radio.
try your FTF file again in flashtool and tick all exclude options EXCEPT baseband
let me know how it goes

Just out of curiosity have you tried: Settings -> Xperia -> Internet Settings?

[Q] Xperia V update from android 4.1.2 to 4.3 / firmware 9.1.A.1.140 to 9.2.a.2.5

Good day, I have a problem with my android and firmware update. I have seen some blogs about xperiaV posting that they already have JB 4.3 update and the latest version of firmware 9.2.a.2.5.. I am wondering how they update it 'cause when i connect my phone to Pc and run the PC Companion, i check the update and it says my phone/tablet is up to date, but the android version of my phone was still 4.1.2 and the firmware version is 9.1.a.1.140.. I don't understand what is the problem of my phone or at my PC Companion Software. I tried also connecting my phone to internet and check for update and still it says my system is up to date. My main concern why i wanted to update my phone, it is because my phone is now dead signal as in no signal (by the way i'm form the Philippines using Smart Communication Network postpaid) I've already switching the network from GSM only and to other choices provided but still no signal. I tried switching my Airplane mode and it displays an airplane icon on the signal area (I think airplane mode is working well, never tried using is). I've read some blogs also that you need to root your phone and flash the firmware and so on to update the android version, but i think its just changing the room, not really updating the system. I don't want to do that 'cause my phone might turn into bootloap 'cause i don't have much knowledge on doing that. I've read also some blogs stating that there is a bug or network issue on version 4.1.2. So i am looking forward from anybody here in the forum who can help or teach me what to do to update my android and firmware version.

I am not sure of it useful to 'upgrade" the phone to solve a problem - this problem of yours. If I were you I'd use the repair my phone option in PC-Companion first, and then see what happens with the phone signal.

You can simly flash any ftf file for your phone with flashtool. Not the sony one. You don't need root access for it

#Mr. Peter-K I've tried it already just a minute ago and still no use. Related to the blogs that i have read regarding on the 4.1.2 version network bug. there problem has been solve after updating the version of there android.
#Mr. Jimmy i'm new here, i hve knowledge on doing flash but i dont have any idea what file to download so that i can update the version of my android to 4.3 and the firmware also. I would like to ask you help if its ok for you,.

Look at this: http://forum.xda-developers.com/showthread.php?t=2648320
Download 9.2.A.2.5 unbranded coming from Singapore or HongKong (since you're from Asia) and follow the instructions to flash.
Good luck

Follow up question. Base on my current system version that i have witch is "Build 9.1.A.1.140, do i need to update my system first to 9.2.A.1.210 or its ok if i will go directly to 9.2.A.2.5?

You can jump straight to 9.2.A.2.5
It's important that you wipe all your data... and Flashtool will do it for you automatically if you don't change anything just before flashing

Mr. Istux got an OT question here. I have concern also on my network set up. I want to unlock my network so that i can use other sim card. My phone is Lock to Smart Communication Postpaid. So i wanted it to be open-line. Hope you can give some advise to solve my concern..

I actually don't know how sim-unlocking works.
Have you ever asked to your network? Usually they give you a code after having paid a little fine.

Back to my thread.still my phone signal is not working. i just found out w while ago that if i am in the higher place like 2nd floor of the building, i got a 2g network and my phone signal is working. but if i'm already at the ground floor the signal is not working. is it ok if i am going to do open line on my so that it will receive any type of network or is it really the software problem of my phone causing the signal not working??

[Q] How to fully restore Xperia Z1

Hi,
Im trying to restore Xperia Z1 original firmware (that can get updates from Sony) and I cant seem to succeed...
I have used flashtool but the software is just not right:
I can't use Wi-Fi, the sim is not working anymore (Im from Israel), everytime the phone get shut down - it asks me in what language do I want to use...
`I have tried using PC companion (Repair) also` but it tells me that my phone doesnt have an update.
I dont know what to do anymore
any advice?

Just download a rom for your model z1 and use, 'Flashtool' to flash the image.

I did that.
The IMEI is gone. Nothing seems to work ...

its probably because the flash version is not compatible with the baseband. Try flashing an older version (for eg. .108 version : u can get it from mega ftf thread in general section) and then after the flash, pc companion should detect and install the latest update.

xperia z1 no signal problem (HELP!!!!)

my xperia z1 suddenly have no signal.
i already tried my sim to other phone, it works perfecting and have a full bar of signal.
i also tried other sim network to my z1, but it also indicates no signal.
i tried to repair it using pc companion, but the problem is still the same.
i also tried hard/factory reset my z1, still same problem.
i can access the sim option and function, but still no signal.
i also try using simcard reader app, it can read my sim card and i can view my simcard information.
so i think my phone simcard reader is functional.
I need your help to solve my problem on my only phone. thank you:crying::crying::crying:

@lonesome10
I tampered once with the radios and selected USA bands, and had no signal but clean reflashing a rom brought it back to life.
You said though, you already tried repairing it through PC Companion so I don't know if you can solve the problem.
If you have flashtool, try flashing an ftf from here and see if that helps, otherwise I can't think of anything else.

i want to downgrade my phone of software.. is that possible? sorry i am new on flashing an android phone..

@lonesome10
Yes it is possible. You wrote you managed to flash an ftf from xperifirm, which means you downloaded the files, and used to flashtool to create an ftf. Correct?
Now go to xperia z1 general section and in there, there is a thread containing stock ftfs.
Download one (preferably a kitkat 14.4.a.0.108), and flat it through flashtool again. Do not check anything in flashtool, that means wipe everything and do a clean flash.
See how that goes.

@yngwie_m,
Yes I manage to flash it by downloading a firmware from xperifirm then create a FTF using flashtool and I flash my phone.
If I download a firmware (preferably a kitkat 14.4.a.0.108), do I have to use flashtool to create a FTF file then flash my phone? or I don't have to create a FTF file and directly flash my phone with the firmware I downloaded using flashtool. I am from the Philippines, is there a firmware that is made for PH user? What is generic/unbranded or branded FW? what is rom and kernel?
Sorry again for the inconvenience, I don't have experience with flashing using different firmware.. again thank you for your effort to solve my phone problem. I appreciate it so much!!!

@lonesome10
On the 3rd page of Xperia Z1 General subforum, there is a thread called "[FTF] C6902 & C6903 & C6906 & C6943 FTF Mega Collection".
On the first post it has all stock uprooted ftfs.
So find which variant you have (C6902, C6903, C6906, etc) and download the corresponding ftf. Any Generic or Global ftf will do.
You will be downloading an .ftf file so no need to create it. Just flash it through flashtool.
Don't worry about roms and kernels. You have to make the phone work again for starters.
Branded is an ftf that contains stuff from a brand, like Vodafone or o2 or whatever.
Unbranded is a clean ftf as given from Sony to carriers.
So to sum up, for starters go to that thread and get an ftf to flash through flashtool.
To check your variant, see the phone package or in dialer press *#*#7378423#*#* and in Service Menu go to Service info -> Model info to see which one you have and download appropriate ftf.

Can I use Xperia Companion to Install UK Firmware?

I swear that when I first got this phone i used the Xperia Companion tool to select the UK firmware to Install it to the device? Everything i see now points to using the Flashtool.
Am I crazy? did i use the flash tool and just don't remember?

I'm pretty sure you can't use Companion for changing region (not sure if it was even available earlier), so you need to go with flashtool or newflasher.

I believe Xperia Companion can be used to reinstall the current firmware you have on your phone, regardless of whether it was the original firmware the phone was sold with.
