[Q] Stuck in bootloop after modifying build.prop

Hey everyone,
I've been eyeing this forum ever since I got my XZ, two months ago. I decided to root a few days ago (that Kingo one click program) and tried to improve my phone a bit everyday.
Today, I tried to hide the navbar by adding that line at the bottom of build.prop. I edited the file with QuikOffice but when I wanted to save, I couldn't simply replace the one there so I saved it somewhere else and copy/pasted it in place of the old one. I shut down the phone and when I tried to turn it on again : bootloop. I don't know how an extra line could mess the phone this much but I'm wondering if I haven't modified some other line without knowing it.
I read that using flashtool was an option so I downloaded an installed SEUS and then Flashtool (EMMA). I connected the phone following the instructions (volume down button) but I got a "Locked phone error". I haven't done much after rooting, especially not setting up a recovery or unlocking the bootloader.
Can anyone guide me through this ? I read things about using an update.zip file but have no idea how that works. I also don't have access to the original build.prop. I've also read people who espaced a bootloop without losing data. But the "locked phone" part doesn't seem to be common. As for the Sony Update Service, it just tells me that the phone already has the last "software version" and that's it.
Thanks.

hm, can you download sony pc companion and try? I used it yesterday and there is a service tab where you can fix and download updates etc. Maybe there is a reinstall firmware or some such

Thank but PC Companion offered to repair the device but at the cost of all data.
I was able to solve the issue and keep my data by flashing a stock ROM using the actual Flashtool and not Emma. I'm not running CM10.2 and everything is looking great .

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] All sensors broke

All the sensors on my Xperia z1 stopped working and aren't listed on CPU-z. Light, orientation, proximity, and the screen never shut completely off when locked while the device is on.
Already tried flashing a new firmware and putting a custom rom and nothing worked. Any suggestions?

Did the sensors stopped working after you Flashed/installed some Rom/Mod/Kernel,etc. ... or it just normally happend?

Just normally

Any news about this? I've the same problem. Tried nearly anything to get rid of this problem.
Afer a reboot alle sensors are working (again). After a few minutes/hours they stop working (don't know when exactly).
I have no apps installed, only the default apps from sony's stock rom ( 5.0.2 / .270 ).
Is there a possibility to reset/reload the sensor drivers or something like this. Don't want to reboot any time.

I've found a way to live with this "bug".
Now, I use "Tasker" to execute the following shell command, when i switch on the display:
kill $(pgrep sensors.qcom)
This kills the sensors.qcom process. ( It will restart automatically )
After this restart, all sensors are working again.

Just do a complite wipe (system,data and all of that) and re install another rom. If it as u say, a software problem this should solve the problem.

Thanks for your reply ... tried it many times. Wiped everything, flashed Stock-Rom with Dual-Recovery AND Flashtool ... nothing helped.
Searched the internet many hours and read, that many people have this issue, on several devices ( Samsung Galaxy S4 / some LG's / Nexus 5 ).
Seems to be a bug, but i don't know when it's appear.

Although unlikely it might be an app, you should try leaving the phone with its stock apps after a fresh install and see if the issue shows up again, then one by on install the apps again, if you decide to this you can pm me the list of apps which you have and I can compare then check them off for you.

Hi,
tried many things again, but nothing works:
- wipe everything and flash the latest stock firmware (without installing any apps)
- wipe everything and flash the older stock firmwares e.g. 4.4.2, 4.4.4 (without installing any apps)
- wipe everything and flash a few custom roms ( cm12, cm11, crdroid )
Nothing helped. After a few minutes/hours in deep sleep the sensors does not wake up again until i reboot the phone.

[Q] Bricked Xperia Z

Hello,
I think I did something really wrong with my Xperia Z. I rooted it a month ago, I have the latest stock rom. Yesterday, I downloaded an app called Flashify on the play store who claimed to be able to flash recoveries and zips directly from phone, as long as it was rooted. I tried to flash the purexaudio mod to my phone, and since then it has become unusable. It first started to be very hot, then laggy, which forced me to shut it down. Now everytime I turn it on, it is usable for barely two minutes, before it becomes really laggy and nothing works or it freezes. Some actions directly crash my phone, such as opening the developers settings. I looked at the RAM usage on the phone's settings and the RAM is filling up progressively until the total 1.8GB of RAM is used and my phone freezes. I really don't know what is causing this.
It gets even worse, as I've managed to factory reset my phone with the sony PC companion, but the problem is still there. I can't access reccovery but I can access fastboot mode. However, neither Flashtool or fastboot command shell will flash a recovery for me (I get an "access denied" error). I can't flash the stock kerne with Flashtooll, I have the message : "Processing of loader.sin finished with errors." (I had this problem when I rooted it but I really can't remember how I fixed it).
I'm really anxious about what I've done with my phone, I hope someone could help me recover my phone as I honestly don't know what to do at this point...
Thank you so much in advance.

Well, that's not weird at all that you're getting "access denied" via fastboot. You said you've rooted your device, but did you unlock your phone's bootloader?

No, I guess I didn't... My bootloader status in Flashtool is : ROOTABLE I'm going to try doing that first. Thank you so much for your fast answer

I have a big problem actually now, as repairing my firmware with the sony software removed the USB debugging option. And opening the "developers settigns" to turn it back on still makes the settings crash. So I have no way of unlocking the bootloader now have I?
EDIT : Okay, nevermind. I managed to unlock the bootloader and flash a custom recovery (Cyanogen recovery). But now I'm on a boot loop (Sony message then Xperia then phone restarts)
What should I do now?
EDIT 2 : Solved the problem by simply wiping all caches/data from my recovery (ended up setting up the more traditional CW recovery) + sideloading a custom ROM (Ultimate PureZ). Now everything's working perfectly.
Thank you again for suggesting to unlock the bootloader, I couldn't have flashed the recovery otherwise. Have a nice day!

You're welcome, but in this case you've made a major mistake - you didn't take TA Partition backup in which all DRM keys are being kept. Now you've erased them permanently, this will cause some stock applications to won't work (camera stabilization and etc.,).
Have a nice day you too

Really? :/ What won't work exactly.?. I bootloaded my phone the official way though...
And BTW that's strange but when I put my SDCard back into my phone it crashed just like before? I guess I should format it?

Guess so. If even will update to earlier version (4.4.x) or later BE2 won't work, as well as camera stabilization (focus, well, it works, but photos are a bit like blured) and some other functions that I don't remember at the moment. It doesn't matter how did you unlock your bootloader, the fact that you've unlocked your bootloader is the most important. I'm sorry, but there's nothing we can do about it (DRM keys recover) at the moment. Maybe in a future there will be found a solution for this, but then our phone, I suppose will be like a nokia 3310 in nowadays.
Btw, you can still get some functions working, just surf this forum for unlocked bootloader functions "Get back" or sth., don't remember thread name either.. :|

Check Fail error

Hello, XDA community,
Since I couldn't find a thread here discussing this problem, I'm starting one now.
Everytime I start up my phone or whenever it runs out of RAM and tries restarting background services/apps, the "First Time Start" application reappears in the taskbar (it actually is com.sonyericsson.startupflagservice) and then the screen opens up the "Check Fail" screen (image attached). Tried looking at ADB logcat at boot, nothing useful (will try again soon). This problem began occuring since Jan 22, when I first started my phone. The phone is not rooted nor messed with (bootloader still locked). Contacted Sony for that, they suggested the obvious and costly solution, to bring it to them so they could examine and fix it, but is there a manual fix? I want to know exactly what is causing the problem and be able to fix it for myself only, since this phone isn't that popular where I live. I have nothing against Sony fixing it, but most probably they won't even explain what caused it (and it happens for me to be a curious person). The phone is bought at RDE.lt , which is a general tech shop, not a phone vendor, and thus no warranty is given.

To be honest, I would fix this by reflashing the phone, either reflash the current firmware (Country and provider the exact same as before)
Or flash a new firmware which is not buggy. It is known that firmwares are not the same as some of them are buggy mess.

Tried reflashing through Sony PC Companion, no go. If I try FTF flasher, is unlocked bootloader a must? I have flashed ROMs before on Huawei u8160, Sony Xperia X10 mini e10i and Xperia Go st27i, but most of them were custom, so I'm unsure if I have to unlock it now.

Download a firmware from XperiFirm
And flash it with Flashtool
It does not require an unlocked bootloader as it is not a custom ROM

Solution
Hey guys. I got the same problem on 20.1.A.2.13, tried to flash the 20.1.A.2.19 twice, tried factory reset but nothing happened, after starting the phone I always got the Check fail message. The problem is caused by the Startup Flag Service 2 (com.sonyericsson.startupflagservice), but I got a solution for the problem. Because it always shows up after the systemboot, we simply just have to prevent it from running at startup.
I used SD Maid (Pro or simple version doesn't matter). Go to App Control, than type in the search box: "startup", tap on it. Tap on Toggle Autostart Components. After that switch the On to Off and reboot the phone. Thats all

Hello, im having the same error. I have installed sd maid. I have searched startup and clicked on it however there is no toggle autostart components option.
