[Sony Xperia T, TL, TX, V] daemin:
Hi there,

I would like to post my 2 cents here too, cause this is bug or whatever it is so annoying that I want to smash my Xperia against the wall.:eek:

It started shortly after I upgraded my Xperia T to 4.3 (.295). First I thought it is caused by wrong USIM placement, but even if I pull it out and follow the click to be sure it is placed properly, reboots appear from time to time. I was trying to track the source of this with "standard" steps like factory reset, installing apps and do settings without using Backup&Restore app, testing another USIM however without success, using phone with/without microSD card. I even upgraded to latest bugfixing .199 today but those damn reboots persists.

Maybe these observations will help to solve this issue:

- reboots appear usually after using apps using internet connection (mostly local news, gmail, Chrome etc) and, whats interesting, when screen is off

- mostly when on HSPA, not wi-fi

- when I play music, using PowerAmp, not tested on other mainly because I have no other installed :p

- sometimes after the call

- once or twice it happened when unlocking the phone

- reboots stops only if battery is totally drained or if I notice smell of the the burning flesh of my thigh and I put my screen on/or reinsert USIM.

I will observe more, but Im loosing patience :mad:

There were no reboots when on stock 4.1.2 with locked bootloader with root. I also had to turn off SIM card lock, because I need to be reachable. I like this phone, 4.3 is nicely done but this is driving me mad. I consider to downgrade and visit my local vendor, but beforehand I decided to ask community.

Sorry if this is discussed somewhere else here, I just spotted this post and added my POW. Thanks for your help :cool:
[Sony Xperia T, TL, TX, V] zy4377340:
it may related to the battery
[Sony Xperia T, TL, TX, V] bruce1x:
mine was the opposite, reboots all the time when tethering unless I kept the phone on charge on stock 4.1.2. now on 4.3 and only had two reboots after heavy usage, but the phone wasn't on charge and was hot.
[Sony Xperia T, TL, TX, V] daemin:
Looks like the reboots are caused by handover between 2G and 3G networks. I have set my T to stick on the 3G only and reboots have disappeared. Two days without single reboot :)

However I have found strange dots on the display recently, like some layer of the display is too thin and light is bit brighter in these parts, so I need to pay a visit to my vendor anyway.
[Sony Xperia T, TL, TX, V] Talgarius:
Theme

Hello. I updated to 4.3 rooted ROM, and always restarted and I cant start the phone when is SIM in. Tried reinstall via CWM, nothing helped. And... yes.. maybe installed programs caused this boot loop, try install step by step program to program and succes. I found Woody theme. When I setup this theme, phone cant process Sim pin code section at start. Deleted theme helped me, and now work fine Darklord Rom :)
[Sony Xperia T, TL, TX, V] daemin:
Well, I have finally isolated issue and it is not related to cellular handovers. Reboots are caused by faulty mechanism holding SIM card in place. Despite I hear and feel obvious "click" indicating SIM card is in place and mounted, it is not. After undefined time SIM card gets loosed and you can take it out very easily. Not sure if this is just me or it is a construction issue, but I saw too many posts regarding reboots. Time to check guts of your Xperia folks..
[Sony Xperia T, TL, TX, V] Felsar:
This reboot issue start happening to me just last night, no Wi-Fi no 3G, just using "UBreader" (reading a ebook, obviously :P) before sleep... it reboots 3 times within an hour calling for "sim/usim card removed"... After third reboot, I open the card holder and removed SDcard, nothing happen, then I remove the sim card and did it again [the reboot] this time on porpuse, so... yeah, I think what [MENTION=5134611]daemin[/MENTION] says is true, the mechanism for holding sim card gets loose after a while... sad but true...

Maybe, when holding the phone, we press to hard on that side without noticing and that cause the problem, I don't know... but this morning I check at running apps and all or mostly all say 7 hours "running" so I think phone didn't reboot after I left it there for sleep... who knows... :eek:
[Galaxy S 4 Q&A, Help & Troubleshooting] jadajada:
I have just bought a new S4. I have had one before and I like to root my phones. I was hoping that this one would come with 4.2.2 so I could keep it on the old bootloader for a while and be knox-free.

It came with 4.3 preinstalled, so I already have the new bootloader, but I am still on 0x0.

Are there any reasons not to update to 4.4.2 now? Is it possible to root and keep 0x0 on either 4.3 or 4.4.2, or do I have to trip knox to root now? I know that I can't install any custom roms yet without tripping the flag (I think).
[Galaxy S 4 Q&A, Help & Troubleshooting] Jonny993:
rooting on stock 4.4.2 kitkat rom will trip knox warranty void to 0x1 and there won't be any turning back.. however, on 4.3 jb stock rom there is the possibility to root the phone without tripping knox warranty void;

so If I was you, I WOULDN'T UPGRADE TO KITKAT! And believe me, I would have rooted it if I was still on jb! But for me there is no other way but tripping knox for root.. I only have to hope and wait to see if someone can figure how to root 4.4.2 kitkat galaxy s4 without tripping knox..

And the reasons to not update to 4.4.2 are unlimited! The very first reason is the fact that non-system apps can't write on the external_sdcard anymore.. this due to limitations on sdcard by Google; and the only way to fix this is to modify a system file, the "platform.xml" in the system/permissions folder.. and you know, to be able to modify that file you have to be rooted. But rooting your phone will trip the knox flag....................
[Galaxy S 4 Q&A, Help & Troubleshooting] qtwrk:
Despite the KNOX, none, since you already on 4.3 so I guess you won't be able to keep KNOX free anyway if you decided to flash
[Galaxy S 4 Q&A, Help & Troubleshooting] jadajada:
How do I root 4.3 safely, while keeping knox at 0x0? I have tried SAFEROOT, but it didn't work:

[*] You phone is detected and ready for rooting.

[*] Sending files to your device...

[*] Starting rooting program.

ro.build.product=jflte

ro.build.id=JSS15J

setsockopt() failed: Bad address.

this device is not supported.

kallsyms_addresses search failed.

[*] Checking if rooting succeeded

[*] Unfortunately, rooting failed. Cleaning up.

[Sony Xperia L] rayleigh2010:
Hi I would like to ask for your help on working with my Xperial L. It is free phone from my network plan so when I checked the unlock bootloader is set to NO. that is my problem at the moment. Is it still possible to root, and port a kernel/custom rom even if the bootloader cannot be unlocked? I hope you could give me the proper steps so I can arrive at the same set up as yours.

Here are the details of my unit at the moment:

Model - Xperial L C2105

Android version - 4.1.2

Build number - 15.0.A.2.17

Bootloader unlock: not allowed

I haven't started anything yet as I'm unsure which to steps to follow, hope if there's someone who had the same details can help me to root and port a kernel/rom.

Many Thanks in Advance!
[Sony Xperia L] Navneet Suresh:
[MENTION=3468820]rayleigh2010[/MENTION]

Yes you can root & also install ROM too without unlocking (Which is risky). Kernel needs UBL so you can never have kernel for your device(AFAIK). Try to get it unlocked from your vendor or ask him for a replacement for your phone and get a Unlock able phone.
[Sony Xperia L] rayleigh2010:
[MENTION=5324073]Navneet Suresh[/MENTION]

what are my options then and what are the risks if I don't unlock my bootloader? I don't think my vendor would change it so I'll just have to live with it.. can you provide me a tutorial please with these limitations..I would be very grateful if you could help me. thanks again.. :good:
[Sony Xperia L] Navneet Suresh:
[MENTION=3468820]rayleigh2010[/MENTION]

Use the below link to root latest build it works (AFAIK).

And for roms CNT ROM has installation option for LBL.

And why? Pro's + cons?

I've always used Google maps just because it's there. Never really looked into others but my friend says Waze is great. My dad says sygic is what he uses.

What's your opinions on the matter?
[Xperia Z2 General] Chad_Petree:
I'm about to preorder the Z2, but there are some things that I need to know before doing it:

1.Has sony had problems with too cold (blue)/ too warm (yellow) screens?

2. The holes on the left side are for a charging dock, that I know but I don't i'll ever use it, does the phone come with a flap to cover it?

3. Do Z/Z1 have been known to shatter easily? I've always thought having a glass back is a terrible idea, and after havinf the Nexus 4 I promised myself I wouldn't buy a phone with a glass back again, I was always so paranoid, it wasn't fun, I still see Iphones 4/4s and nexus 4 with cracked backs :crying: , I know the Z phones used to come with a screen protector out of the box, but I'm interested in the stories of people who took it off, since the new Z2 does not come with this protector anymore.

4. Can you get rid of that ugly bar with icons when you multitask to put some kind of widgets on the homescreen?

5. Is it true that the corners have been softened? They look identical to me on pictures

6. how long did it take developers to unlock the Z/Z1 bootloader? I'm not planning on flashing roms ever again, but I like having root and couldn't have an android phone without xposed :laugh:

7.Why was the battery life just ok with the z1? It has a 3000 mah but the LG G2 for example lasted quite a bit more with the same battery capacity and so did the Note 3 with a considerably bigger screen

8. No hope for a 32 gb version?

9: Does the phone have qualcom's quickcharge 2.0 like the G2? The LG G2 battery charges in under 2 hours! The Z1 doesn't have it, it takes the phone 3 hours to go from 0% to 100% :(

Thanks guys :highfive:
[Xperia Z2 General] :
Can't answer every question but I'll do my best.

1. The Z1 has had problems with warm screen colors. Actually to an extent that they made an update that brought a screen calibration app to help with the issue.

2. At least my friends Z or my Z1 didn't cover the magnetic charger pins.

3. No, the Z1 has actually been surprisingly durable in drop tests and there doesn't seem to be many complaints of shattered glass. Sony claims that the Z2 will also be shatter resistant even though it doesn't have that ASF (anti shatter film)

4. Not sure what bar you mean but you can add widgets like any other Android device.

5. This is a claim about the lens and even though it may be valid I haven't seen people complain much about this. The problems with the past Xperia phone cameras are with software and processing mostly.

6. Sony gave instructions and tools to unlock the bootloader for everyone and I believe they will continue with this trend - this is basically a non-issue. Unlocking the BL on the Z1 did remove access to some of Sony's proprietary software though such as Bionz which then affected picture processing negatively.

7. The battery life was greatly improved with an early update and is now a lot closer to the LG G2

8. Never seen even one Z1 with 32GB... But they all have micro so slots.

9. The Z1 doesn't have quick charge however I don't know about the Z2.
[Xperia Z2 General] Chad_Petree:
So that's why they created the calibration app, haha I was so naive I thought it was just because they wanted to give the customer some extra tweaking options .

What about scratches?

I meant this bar :

And I meant the corners of the phone , I've read the corners of the z/z1 dig into the palms of people

And the camera issue with the sides of the picture concern me, I'm thinking its a hardware issue because the z2 samples show the same situation :'( check out the grass on the left and right corners :'(

OK Sony provides with instructions to unlock the bootloader but does it void the warranty?

Gesendet von meinem Nexus 5 mit Tapatalk
[Xperia Z2 General] :
The ASF is extremely easy to scratch but I haven't heard about people having problems with the actual Dragontrail screen under it and I doupt the ASF-less Z2 will have issues with scratching.

The corners of the phone I guess can be a little rugged but I haven't had an issue with that and they don't dig into my hands. I suppose it's up to people depending on how and where they hold the phone and how large their hands are. The Z2 indeed seems the same corner-wise as the Z1.

And yes, unlocking the bootloader does void warranty as it does with all manufacturers, however at least with the Z1 it could be rooted without unlocking the bootloader. Also it's possible to go back to a factory looking state (unlike Samsungs Knox which will always show 0x1 even if tripped).

Could you please reload the attachments or upload them to flickr/dropbox? I can't see the attachments at all.

---

Edit: If the picture quality concerns you then I suggest waiting until you can see more pictures from commercial units. The Z1 has it's issues and due to the same hardware it is entirely possible those will follow to the Z2.
[Xperia Z2 General] Chad_Petree:
I thought the xperia z1/z2 used gorilla glass 3 , that's interesting .

Yes HTC does that too but a couple of months after the release of the phone ,developers make "s off" and you get to unlock your bootloader without voiding the warranty .

You're right I should wait a bit to read people's opinions, I saw no mention of this issue on reviews :/

I reuploaded the attachments :)

Gesendet von meinem Nexus 5 mit Tapatalk
[Xperia Z2 General] :
Dragontrail should be just as good as Gorilla Glass - it's just a different product for the same purpose.

I have HTCs One X and to this day it doesn't have S OFF. The grass always seems greener on the other side :)

That issue you mentioned in pictures, I never saw it in Z1 reviews either. I first bumped into it here at XDA.

And oh THAT bar. It's just for opening up mini apps that work a bit like floating video from Samsung i.e. on top of the system. Widgets are added from the home screen settings as usual.
[Xperia Z2 General] Chad_Petree:
I'm not saying it's bad ,I just thought gorilla glass had a monopoly on the high end .

I didn't know the one x didn't have s off :( , now I'm confused, s off is basically unlocking the bootloader but without giving HTC your serial code, so you can keep using your warranty, right?

Yes that's the bar I meant, can you get rid of it ? I don't like it :(

Gesendet von meinem Nexus 5 mit Tapatalk
[Xperia Z2 General] :
No, S OFF is basically access to a certain portion (NAND) of the device which is locked and unwritable when S ON. In a nutshell - read around the internet for more information. But not every HTC phone has S OFF so development on those phones isn't always any better.

And I don't think you can get rid of that bar because it's literally the only way to open those mini apps. You can just ignore it.
[Xperia Z2 General] Akiainavas:
From all the tests I've seen - Dragontrail is not as scratch-resistand as Gorilla Glass, but it's a lot harder, able to bend and survived in most cases where GG shattered during tests.
[Xperia Z2 General] vicedens2002:
This thread answered me a lot of questions. I hope I will dive into z2. Currently having HTC desire HD. Only I miss is the IR
[Xperia Z2 General] rowlers:
Yep this is an informative thread... Answered many of my queries too!

What are sony's like for flashing ROMS? With my s3 it's very easy - I can download and flash on the go. Is this the case with the z1/z2?
[Xperia Z2 General] stress40:
Yep, I agree that this is a very informative thread. I am also curious about the flashing aspect of the z2 and Sony phones in general. Like the guy above me, I have also nearly flashed my s3 to death. As this will be my first Sony Android phone, are they as easy as my s3 to root and flash? I have been on the other forums and trying to read and see but, it gets all a bit confusing with info here, there and everywhere lol. I have my z2 on pre order so have made the commitment to jump ship already. Will be sad to see my s3 go :crying:. It has been a great phone. Anyway, heres to a great future with an awesome phone :D
[Xperia Z2 General] :
Sony gives tools and instructions to unlock the bootloader and flashing isn't too difficult. The process is different from flashing with Samsung though. It even used to be possible to root without unlocking the BL but they have made that harder in later updates at least on the Z1. You need a computer to root and install the recovery but after that flashing can be done rather easily.

You have to be sure to install a recovery and do a backup before unlocking the bootloader or you will lose a partition that holds Sony's proprietary DRM keys forever

(they are unique for each device). These keys hold access to BIONZ and some other tech/software that isn't accessible on unlocked devices.
[Xperia Z2 General] stress40:
Thanks man :good: That's the most important bit I was looking for. So, you can install a standard recovery like Phil's touch etc? or have the devs. made one specific for Sony phones? I think I may have to buy a second hand Sony for a bit of practice lol... Anyway, thanks for the reply and info mate :D
[Xperia Z2 General] Why So Serious?:
I think one really important thing that the people new to Sony need to know is that when purchasing via a carrier, the carrier can disable the option to unlock the bootloader and there is literally no way around this.

To this date, the devs have still managed to obtain root and recovery on Locked Bootloaders but it has become more and more difficult (I'm not even sure if the latest Z1 or Z1C firmwares have been rooted yet - could someone confirm?), but custom ROMs and Kernels that aren't based on stock can't be done.

To ensure you get a device with an unlockable bootloader, avoid purchasing through a carrier. I'm pre-ordering mine through Clove as they don't sell locked down devices.
[Xperia Z2 General] :
Yes, most standard recoveries work including CWM, Philz and TWRP

This is true but carriers also do this on other devices, they aren't singling out Sony. Especially American carriers do this.

So my next tip is really a general tip, not just for Sony or Z2:

If you want a phone with development opportunities, get an international edition if possible because they usually don't have locked bootloaders like carrier versions. Secondly be prepared for issues; manufacturers are complicating flashing and giving a hard time after unlocking bootloaders.

- Samsung has Knox (bye bye warranty)

- Sony has proprietary DRM stuff that will be gone after unlocking

- HTC has S ON

Etc.

It seems that gone are the days of fully accessible development unless you get a Nexus or Google Play Edition.

[MENTION=2770867]akselic[/MENTION]

Thanks for the rely m8 :good: .

Yeah, I only buy unlocked phones anyway. My days of buying carrier branded phones and being tied to a 2 or 3 year contract are long gone. Just now, I am on a 1 year plan- mainly network access i.e. 3g unlimited with 3000mins for €20 month (calls to any network included) sim only. So, in April I will go and haggle a new LTE one for another year :laugh: . Like most carriers, it is easy to upgrade before end of year.

Let's see what the z2 brings in terms of modification potential. Can't wait :D
[Xperia Z2 General] vicedens2002:
Thanks guys. Few posts above clarifies another set of questions. Actually what is the need for unlocking a boot loader. Because root and recovery and custom roms can be installed even with locked bootloader, it's hard but it can done right? There are custom roms based on stock Sony Rom? Another thing, if google announces z2 google play edition. We still be getting the play edition updates unofficially?

P.S..Am coming from HTC Desire HD. Which has been flashed a zillion times in the past 3 years.
[Xperia Z2 General] Sensamic:
Sounds difficult. Didn't know all that stuff about Sony phones: losing DRM keys, etc.

So what happens after unlocking and rooted? Does this DRM keys and propietary software get lost forever? Then you can't go back to stock Sony rom? Or you can but there are things that won't work?
[Xperia Z2 General] :
No maybe I was being vague, sorry. Rooting and recovery installing was possible without unlocking the bootloader. They made it harder in later upgrades though. You need to unlock the bootloader to be able to install custom roms or kernels.

There are both AOSP based roms and stock based roms for the Z1 and I think the Z also.

I'm not able to answer about Google Play Edition - there never was one for the Z1.

If you didn't backup, then yes, the DRM keys are gone for good. You can go back to stock but some things including BIONZ won't work.
[Xperia Z2 General] Chad_Petree:
Can you root the xperia z1 with 4.3 out of the box without unlocking the bootloader? Like I said , rooting the xperia Z2 is my only concern , I'm done with flashing custom kernels and roms.

There's a google play edition of that monster called the Z ultra, sony should market it like a tablet, it's even too big to be a phablet :eek:
[Xperia Z2 General] :
Out of the box you could. It came with 4.2.2 though. It got more difficult after some updates, I think 4.3 was one of them. Not entirely sure can you still root without unlocking now as I returned my Z1 due to a faulty touch screen.
[Xperia Z2 General] vicedens2002:
That seems bad. I will be keeping the phone for alteast 3 years. Till they release official roms, I will keep the phone as stock. Once Sony drops support I will install custom roms. What does the DRM keys have ? Bionz and?
[Xperia Z2 General] :
BRAVIA/X-REALITY engine and BIONZ are the ones affected at least. In other words Sony's copyrighted screen and camera tech (software).
[Xperia Z2 General] vicedens2002:
That seems too bad. I rarely use camera but display tech is very important.. may be I will switch to HTC New One, but I hate it's bezels...
[Xperia Z2 General] Felimenta97:
X Reality is only activated when viewing images (with Sony's Album app) and videos (Movies app, Youtube and MX Player with H/W+ mode). It does help a lot, but is only activated at those times.
[Xperia Z2 General] SwiftSmoke:
Hopefully it's just like my tab z, that you can root only without effecting bootloader then make a backup of TA which holds the DRM software keys for any Sony software u might break unlocking bootloader. Then have option to unlock bootloader if wanted.

As far as I know unlocking bootloader is only needed for installing roms with custom kernels. I could probably get most mods I'd be interested in with xposed and root only.
[Xperia Z2 General] Chad_Petree:
If we have the same situation on the z2 then I'm sold!

[Xperia Z2 General] vicedens2002:
Is it possible to relock the bootloader and make things work again like its intended?
[Xperia Z2 General] :
If you took a proper backup before unlocking then yes, you can go back to a stock like state.

This is what I'm looking for in the Z2 too. I just want to be able to have full control of my phone and get rid of crap I don't use. So bring it on. Hell a month is gonna be a long wait :eek:
