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?

Find them in post 3 of the all in one thread.
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] Update Help

So today i got a new unopened xperia Z from a friend for free
So i went on connecting to my WIFI it shows that the device needs to updated to frimware 10.31.A.2.67
(which i later learned that it was a update released in 2013).But i didnt update.
My phone is in frimware 10.1.A.1.434 which i guess is an old frimware.

You can install SONY PC companionon your PC and use that to update your phone.
If that still doesnot help, you can use flashtool which is unofficial way to upgrade/downgrade your phone.
You would need FTF from general section and also flashtool which you can get from here. Make sure the FTF is device specific or your would end up bricking up your phone

You can search xda for how to use it. If you still have questions, quote me and I would be glad to help

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:

Did you drop the phone or hurt it physically? Sounds like a hardware issue to me.

no sir.. no physical damage at all..
do you think flashing it can fix the problem?
thanks sir

@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.

@yngwie_m
thanks for your reply.. I have no idea regarding flashing of my xperia.
can you send me a tutorial on how flash xperia z1. I want a stock firmware flash.
again many thanks..

I am now on my Xperia. When I get back home to my laptop I will try to gather links and make a fast tutorial. Or if anyone else can do it that would be nice too.
Will be right back.
No need for thanks. I 've been to where you are now it was annoying.

@yngwie_m
I already flash it using a ftf from xperifirm. no changes, still no signal from my network.
i am still hoping that i can solve this problem...

In that case I am out of ideas too, and close to thinking it is a hardware issue.
Because in my case flashing a clean ftf brought it back.

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.

Updating issue

hello everybody , So, i bought this XZ2 a while ago on some one that labelled it as "Slightly used" and been using it for a while now and its been working okay apart from the fact that it randomly overheats some times . I think the phone is refurbished.
The other Big issue is that ive been stock on the same software version since i got it wich is : 51.1.A.2.213. The update manager finds an update wich is : 51.1.A.3.159 and downloads it normally but then faills installation at 99% and tried again maaany times always the same. i also tried with Xperia companion and its the same
So is there any sollution to the problem , i note that i dont have much knowledge on software and i dont want to accidentally brick the phone

If you have the original packet with the phone name you see the hardware revision somewhere.
At least revision 2 is okay.
Revision 1 was not available for sold.
You can use xperifirm to download the latest firmware and newflasher v13 to flash the phone in download mode.
You'll find the download mode manual in the TWRP thread.
Feel free to flash the phone country you want but maybe a different firmware needs a full wipe.
And what's important, remove the userdata.sin if you don't want to full wipe the phone.
But a full wipe may fix your bugs.

Thanks a lot for the answer. no risk to brick the phone if i do a mistake or something goes wrong ? i want to update the phone to Pie should i look directly for the Pie update ?

and i also read that it was possible to fix it by using the "repair" Function on Xperia companion which way should i go for ?

Of course you can try the repair function.
About the brick.
The worst thing happen is that you need a full wipe to fix a bootloop.
But btw I recommend a fullwipe after pie upgrade in your case and Everytime if you switch an entire Android version

Maybe your phones bootloader have been unlocked.
Then it will fail on OTA and also in Xperia companion.
You can se the status if you put this in the dailer *#*#7378423#*#*
