My 3g/4g doesnt work after flashing - Xperia Z Q&A, Help & Troubleshooting

Yesterday i decided to flash and update to .253, but unfortunately i soft-bricked my device. So, i used sus to get it back, and then i flashed a 434.
I rooted the device, and installed CWM. Then i followed the guide to update with root. So i used CWM to flash .253, and then i used flashtool to flash the ftf. Everything works perfectly except my 3g/4g. It just doesnt seem to work!
Any advice?
Thanks!

Check your apn settings.

[Q] 3G on custom ROMs

Hi guys, finally decided to put down my sensation and move onto the Galaxy S III. I'll miss it =[
So I've bought a UK Galaxy S III I9305 from T-Mobile.
I've managed to root and that and it everything was working fine so I thought I'd flash some ROMs and see what one I like. I flashed two of them (Pandoriam and rXTREME). They worked fine except mobile data would not work on either of them. I followed some instructions in the thread which said to turn on GSM only, restart then switch back to WCDMA. But it still wouldn't work. I flashed different radios as well (or modems as they're called for samsungs) and that didn't help either.
I've just flashed a stock 3.1.2 EE firmware and the device is back to complete functionality and the 3G came on immediately. I also noticed when I booted the phone the first thing that popped up was a box asking if I wanted to enable data connections; this never happened on the custom ROMs. I figured it must be me or my device since it didn't work on both ROMs, hence my posting here instead of their threads. Am I doing something wrong here?
Any help appreciated. Cheers.
Did you check the apn settings? When I flashed those roms I had to re enter the settings again

Ah this wasn't suggested. If you can be bothered could you possibly outline what I need to do. I know how to get to APN settings, do I just note down what they are now on a stock ROM and set them the same way on a custom ROM?
Thanks.

Xperia T can't perform root actions

My XT used to be fine: unlocked bootloader, rooted, could uninstall what I wanted...
But as some of you know, after flashing Sony's JB ftf, and following root methods, the SuperSU apk is installed, but doesn't work...
My phone claims to be rooted... but no system apps can be uninstalled, I have now realized that this is permanent. I have flashed CM10 and the deletion of system files still fails...
Thanks in advance.
P.S. Just encase you tell me to try again or that I did something wrong, I DEFINITELY did stuff how they are supposed to be done and tried many times.

Yep, checked, the permissions are also correct.
have you tried to factory reset and reroot device could be a glitch in the matrix
I noticed that I removed system apps with doom kernel and that when I flashed stock kernel the apps were still there... I thought I had this problem as well. But I removed them again using titanium and now they are gone.
One thing to note. I also rebooted my phone for the first time last night and when it rebooted I got the grey triangle thing. I left my phone overnight and now it's fine... Not sure if it's related but...

Nope did that, not working.
Doesn't even allow me to remove apps when using Doom Kernel...
Which method are you using to remove them?
Are you using titanium or removing the apks from system\app using root explorer

Uninstalling via ES File Explorer.
I also cannot delete the apks.
Then when flashing a new ROM (even after wiping everything), still no luck.

I'll use Sony's flashtool and go back to ICS, that should fix it.
I might just have to wait for the official update, things might work for me then.
Have you tried flashing supersu and binaries in recovery? You can download it from chainfires thread
Sent from my LT30p using Tapatalk 2
Or just use the pre rooted zip from timin8r in development section (stock, rooted and deodexed).
Also kernel is flashable trough zip so all you need is cwm to start with.

Yep, tried all of that, still didn't work. Very strange. Flashed stock ICS ftf, just gonna wait until the JB update is available on Sony Flashtool, things might work better then, for some reason.
I've heard about some system apps being not just in the system folder, but in another folder too (might have been data?) It's happened before that people delete the one in the system folder but the app pops back after a reboot... probably won't help, but always worth checking?

Going to try my luck with the new kernel with recovery.
EDIT: No, still not working...
Thought about formatting all partitions and sdcards, and then flash ftf , boot, flash kernel with twrp, boot, flash superuser and/or update.zip?

I've got Polish 370 and BT works fine.

DJ-Tumor: I have a European version of Tablet Z. Originally, it came with .344 firmware which I rooted using some method floating around this forum. Then the update to .370 came. First, I installed OTA RootKeeper as advised by someone and made a backup of the root. Then I simply updated the tablet using the built-in Sony's Software update app.
After reboot, the system was still rooted. I am not sure if root survived the update or RootKeeper did it (I am not really familiar with the application). Nevertheless, I now have .370 rooted system and can verify that Bluetooth works fine (I just tried it and it discovered two BT device).
I have the 16GB model SGP311.
Good for you guys....but I still can´t update (Update impossible it says even though I ONLY ROOTED IT).
But what I wanted and seemingly no one understood... I NEED EUROPEAN FIRMWARE 344.
I have a feeling that it´s the Japan firmware why my tablet has infunctional Bluetooth.

4.3 OTA ML2 Root Method!

Hello there fellow XDA peeps. I figured out the way to root the OFFICIAL OTA 4.3 Update. Build Number UCUBML2.
1. Download the the following file http://www.mediafire.com/download/x4n952wzyr3eobd/pwnedkernel.tar.md5 and flash it with odin under PDA. I pulled the boot.img from the 4.3 leak and as we all know it is vulnerable to saferoot and other root method around.
2. After phone reboots enable USB debugging mode try using saferoot or Vroot..google it... it will work .
3. Because this is an older kernel, wifi and some other stuff dont work but dont panic. Flash the next file https://www.mediafire.com/?08j1wqn0x7igjq0 with odin under PDA . This is the stock ML2 kernel.
4. After phone reboots launch Supersu and allow the binary to get updated. Also disable that pesky Knox :laugh:
5 .???
6. Profit. Enjoy your rooted apps and safestrap :good::good:
P.S. I have the 4.2.2 modem because I had to repair the imei of the phone..but just ignore it. and again enjoy
Credits to all the people that came up with the kernel exploits like Saferoot etc.
confirmed root access for 4.3 OTA Ml2 worked perfect .. thank you man you are amazing
