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] 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.

HELP: Upgraded from stock 4.2.2 to 4.4 and lost network connectivity

Hello All,
Tried searching for a case peculiar as mine, wasnt able to find one so here is the lowdown.
1. Xperia C6603 , originally had 4.2.2 stock ROM which was working fine with my local network. Dont remember the baseband version.
2. Used XperiFirm to download the latest firmware as reported in the list. Dont know what does the suffix RxD (R1D--R8D) means. Anyone please explain. As per the below screenshot downloaded version "C6603_Customized HK_1270-5695_10.5.1.A.0.292_R1D" .
3. Before flashing the downloaded firmware I flashed the dualrecovery from XZDualRecovery. I made a TWRP backup of the 4.2.2 stock ROM on an external SD card, for all partitions including TA,system,boot etc.
4. Used Flashtool to convert the downloaded (step 2) firmware "FILES" format to a flashable FTF file. Flashed the firmware , which went on smoothly.
5. At the first startup I got the following screen , telling me that it is a prototype device/firmware . I went on to see that the network which was working fine with stock ROM 4.2.2 was no longer available.
I tried to go to settings to check and search for networks, which shows available networks, but unable to get itself registered to the SIM providers network. Tried all the settings combinations in menu "*#*#4636*#*#" , nothing makes it work to get the GSM network connectivity back. It is supposedly on the correct setting of LTE/WCDMA/GSM which my current operator supports. Following is the "About" screen for current baseband version.
Tried going in the "Service" menu via "*#*#7378423#*#*" , with the following info, having an unknown modem configuration.
6. Tried reverting back to the old TWRP backup, for which I needed the TWRP recovery loaded on the phone. So ran the XZDualRecovery script again (with the new 4.4 ROM on the phone), however the script hangs around in the end and never reboots the phone with the TWRP recovery. So i am unable to revert and use the stock ROM backups .
7. I dont want to root/unlock the bootloader, however I tried installing TWRP via its "XZrecovery.apk", but it requires busybox (which requires a rooted phone). So i tried the rooting script from [GUIDE] How to root 10.5.1.A.0.283 / 10.5.1.A.0.292 [Locked Bootloader], but it also hangs around in the end and never delivers a rooted phone.
8. Tried looking around for assortment of xperia Z baseband files to check and see if flashing it separately can make it work, however to no avail the the condition persists.
Either ways having a prototype version on the phone which transmits all data back to sony is not desirable at all. So need to replace it for sure. Currently I am stuck in the middle without a clue of how to go back and restore the 4.2.2 TWRP backup, or to actually flash a "non-prototype" or retail version of 4.4.x .
Any help/guidance/suggestions to remedy would be appreciated.
Thanks.
=====================UPDATE
Ok followed the instructions at [GUIDE] How to root 10.5.1.A.0.283 / 10.5.1.A.0.292 [Locked Bootloader] , read carefully again to flash the .230 kernel. Flashed the XZDualRecovery and got the TWRP recovery back.
Restored the old 4.2.2 TWRP backup , hoping that everything would go back to normal. However with a successul restore and a reboot, I was amazed to see I still have no network connectivity. The baseband version is "9x15A-ACEFWMAZQ-30110068-44" . Another noticeable thing was that after the restore and first boot, I still got the "prototype device" message again, which was not there when I first booted the device with original stock 4.2.2 ROM before this flashing adventure began.
Any ideas what may have gone bad.
Thanks.
=======================================
Just got to know that my device is a BROWN device, its IMEI number starts from 0044 so it is a prototype. Any ideas is it really good or bad to have one. Also I see that after another restore of the original stock 4.2.2 ROM it is barely getting the signals indoor (1 bar only). The signal reception is very weak and sporadic . Should i keep the device or not and is there any remedy or network signal strength.
Thanks.

Firstly I love the detail you have provided which would save you and me a lot of time to pinpoint the exact problem and work it accordingly.
Firstly, I would suggest that if you have a box or any other receipt that shows your exact device name with its basebands. Where did you buy it from and what is your exact location so we can guess your region. This is the time to show it now. Also which basebands work in your location can also help us out.
The problem you have made it flashed basebands of a different variant which has resulted in loss of network. So to fix it we need, and there are three ways about it.
First, download Sony PC companion and try to repair your phone and see if that helps.
Secondly, download flashtool and ftf for your device (make sure you select the right variant this time. Choosing for wrong device can hard brick your phone. so beware) and flash your phone with it.
If all this fails, you go to Sony flashtool called Emma. Download it and try to flash it with that.
You can google how to use every tool on xda and I am sure you would find a lot of guides for that.

Z1 AU SOl23 No simcard could be recognized

Hi everyone,
I use rom 5.1.1 for Z1 C6903 to upgrade my phone (Z1 AU SOL23).
In previous time I used flashtool 0.9.18.4 to flash rom 5.0.2 C6903 (I ticked at Exclude Partition and Baseband). And everything is ok.
But at this time I used flashtool 0.9.19.8 to flash rom 5.1.1 C6903. In this version of flashtool have no BASEBAND option and I can only tick at PARTITION. And now I can't receive incomming call. Outgoing calls and receive SMS is ok.
And I tried to flash to original firmware 4.2.2 (SOL23_KDDI JP_1275-6766_14.3.C.0.239_R21C). My phone say "No SIM card could be recognized and the phone can only be used offline, with Wi-Fi, and for emegency calls"
I continue to try to flash C6903 5.1.1 firmware by flashtool 0.9.18.4, I ticked at Exclude PARTITION AND BASEBAND but the Baseband still be upgraded to newer version and the phone recognize simcard but can't receive calls
Formely when I tick at Eclude BASEBAND and it keep old version of original firmware and I can receive incomming calls.
There a way to get rid of "No SIM card couldbe recognized"?

I've just found the solution, that I go to Setting => More => Mobile Networks => Network Mode => And select Overseas Auto. Then the phone recognize my simcard immediately. And I flash one more time 5.1.1 International firmware. Now all things work like charm
