Hi everyone, i'm new to xda forums and is complete noob. I recently tried to flash a .434 ROM in order to root my device. I followed the guide posted on (http://forum.xda-developers.com/showthread.php?t=2240614) the forum on how to do so but when i boot the device afterwards i get a message saying my NFC is updating do not turn off the device and the phone restarts and continues on bootloop cycle.

Xperia T - Not possible to turn on Wifi after Updating to Android 4.3

Yesterday I updated my Xperia T to Android 4.3 via Sony Companion Software. My phone is not rooted. Everything apperently went fine, but after the Update process I wanted to turn on my Wifi, but it did not work. I tried that from the quicksettings and form the settings directly. The button remain grey for a certain time and the turns back to off.
I turned off my phnone and on again, but a white triangle with a screw came and the phone remained in that status for more than 6 hours. After that it turned on, but the Wifi problem remains. Regarding Bluetooth, that works fine.
What I noticed is that when I check the phone info and the Wifii settings, no MAC Adress is listed there for Wifi. I don't think its a hardware problem, because everything was fine before updating.
What should I do? I am afraid to turn my phone off bcause it could go back to the white triangle remaining for several hours in that state. I dont think a factory reset would help, because there seems to be an update problem and I would like to rather not loose all my settings.
Any help would be very appreciated, because I urgently need wifi in my university.......

The ftf file is the stock Rom, you can find it here on xda. Flashtool also. Flashtool only works if you have windows xp, vista 7 or 8. Not on 8.1. Repairing it using pcc should be easier though

Tnx again. Regarding stoch Rom, I think I am a newbie in that field. I will try to repair via PCC. I have sony bridge for Mac or a Windows PC with Windows 8.1. Which one would you prefer? I updated to Android 4.3 on a Windows 8.1 PC. Do you think that might be a reason, why there is an issue with the update process or something went wrong?

Windows 8.1 works with one of the updates the launched not so long ago

Unfortunately, reparing it with PCC did not help and I am quite desperate. I bought the phone last year as a used one. I am quite a newbie in this field, but could it be, that the rom installed is an altered one and a normal update via PPC leads to this Wifi problem? Normally that should not be the case, but how can I find that out what is causing the problem and what must I do to overcome this drama of mine. I whish I didn't perform that update, because everything wAs working fine before.....

Bluetooth conflict with wifi
I just upgraded to the latest build 9.2.A.1.205 and bluetooth and WiFi seem to conflict with one another. To have Wifi working i have to stop Bluetooth.

A factory reset would definitely work. You don't know how many times I've seen people (even with different phones) have problems like these because they change their Android version and/or flash different ROMs without wiping their partitions, i.e., doing at least a Factory Reset. If you were rooted you could try deleting the "wpa_supplicant.conf" file in /data/misc/wifi. The problem is, since you're already on 4.3, there is no sure way to root 4.3 unless your bootloader is unlocked. So unless you find out a way to backup your data/settings, you're either going to lose it all when doing a Factory Reset, or downgrading to 4.1.2 (to root), or even flashing a stock 4.3 FTF, because I'm sure your problem is that you haven't wiped.

[Q] Bootloop on C5302 - No ROOT, 4.3

Hello guys.
Almost 2 weeks ago I had a really strange issue with my SP. I force stopped a Sony Select app, and then my device got in bootloop - over and over again, never stopping. I got home and repaired it successfully with PC Companion.
Now, it happened again... But it wasn't Sony Select Force Stopping now. I changed my theme - to a downloaded one; the wallpaper wasn't showing. Redownload the same theme - the same issue. Then I also got no wallpaper on the other themes... I thought of restarting the device. Then, SURPRISE! Bootloop.
Now I am repairing my phone again using PC Companion.
If anybody knows what causes this issue, please let me know, I never ever rooted this device, only upgraded via PC Companion, not other sources.
Thank you.

It's probably hw problem. If you still have warranty take it to the repair center.

What if you flash the last rom where it did work.

Sony Mobile Flasher stuck on getvar:max-download-size (Flashing Xperia 10)

Hello,
I got my Xperia 10 into a bootloop. I'm still able to enter recovery, but I've never been able to get out of the bootloop, no matter what I tried.
I started trying to flash software onto it with Sony Mobile Flasher. I'm using version 0.9.28.0. Every time I try flashing, the process gets stuck on the same line:
Sending getvar:max-download-size
Does anyone know what exactly this means or how I can fix this?
Any help is greatly appreciated. :good:

Did you find a solution, I am facing the same problem.

The problem stopped occurring.
However, I began having problems with the missing flash script. I fixed that and was able to flash firmware from XperiFirm.
Do you have a missing script file as well or is it just me?

Update
Here's an update.
The problem with getting stuck on getvar:max-download-size only occurs if it's the second time flashing the device after initial connection (and any attempt after that I guess).
This means, connect the phone, try flashing. If for some reason you try another flash without disconnecting the phone, it will get stuck.
This has always helped me, not sure if it's a universal solution.

Delete all of them! The one in the partition folder too! Then drag the rest of the folder into the Newflasher folder and then follow the instructions on the Newflasher page

I see. Thanks! Just curious, that applies to all Xperia phones and all ROMs or is it different for older ones?
Also, is a flash script needed for NewFlasher. I don't think one is, but I haven't looked into NewFlasher as much as I should have.

I think it's for all Xperias after 2019! No flash script needed. You just have to have fastboot drivers and the drivers for your phone! No need to have your bootloader unlocked either.

You can use newflasher(https://forum.xda-developers.com/crossdevice-dev/sony/progress-newflasher-xperia-command-line-t3619426 to flash the firmware

Tried via newflasher, deleted all .ta files, even in boot folder, but i got again and again getvar:max-download-size error. Any solution, please?
Edit: Solved. Forgot to tap on usb debugging option and then allow to computer
Solutions:
1. Tap many times build number to open developer options
2. Turn on usb debugging
3. Connect phone via cable while it is turned on and press Allow when computer asks in it
4. Then try to flash android 10. Write n n n to commands, no need any gordon driver or etc
Maybe need restart phone and pc one time, when you turn on usb debugging and then Allow it
Also i installed android driver, after connect via cable, it was yellow ? <= that sign (in computer > manage > device manager)

Try closing the program and opening it again.
Make sure it's always the first flash after opening the program.
That's what solved it for me. Though honestly, this was more than a year ago , new versions of FlashTool might not have this problem anymore? I honestly don't know, haven't tried in a while.
