I've been trying to figure this out all morning and I was directed here.
Basically, I locked myself out of my phone and I am unable to unlock it. I cannot transfer data from computer to phone or phone to computer without unlocking it first. I cannot move or look at the data without unlocking it first.
I tried downloading the dr. fone unlocker, but that was incompatible with Xperia XA2. I did read the rooting guide, but I didn't see Xperia XA2 listed in the compatible phones section.
As far as I'm aware, this means no data or code can be transferred from computer to phone or phone to computer. Given that, I'm not sure how I could possibly remove the lock screen without losing data, but I'm hoping the tech geniuses on this forum can help. This is so far outside my realm of comprehension, I honestly do not know where to even start. Hopefully somebody else does.

I bought this tablet 2 months ago in our local t-mobile. And everything was fine until 2 weeks ago when it suddenly started loosing gsm signal.
At first i thought it had something to do with me rooting it. So i tried repairing it 2 times but with no luck. After that i tried downgrading to 4.1.2 and that didn't work either.
So basically i can be online (surfing,downloading etc.) for few minutes before it drops gsm signal (no signal icon in statusbar) and after few minutes it comes back and then it drops again...
I'd like to know if it can be fixed without taking it to nearest sony repair service. Did anyone encounter similar problem and manage to fix it?
btw bootloader is locked (unlock allowed: no) so flashin another kernel/ROM is out of the question...

Have you tried factory resting it ? Also you can unlock the boot loader just search xda im sure ive seen a guide somewhere ? i was going to say take it back to Sony as it might be a hardware problem but since you have rooted it your warranty has been voided...

Well firmware flashing via SUS repair option usually does that for me.. but yeah, i tried factory reset as well. And about bootloader unlocking i've been searching for a guide ever since i bought it. No such luck... Apparently if it's "bootloader unlock allowed: NO", it's meant to stay that way. At least until someone finds a way around it.
I've got a vague idea about how does rooting work and that tells me if i did a complete wipe and flashed my tablet, how can they detect it?
I mean.. it's a complete reinstall, how are they supposed to know that the tablet was rooted on previous firmware if it currently isn't?

Well im no pro, but don't they have some kind of binary counter witch tells the manufactures the devices has been rooted ? i know that's how Samsung goes about identifying if the devices has been rooted... But Sony im not too sure, Also your theory does hold ground, if you clean install from the ground up then Sony shouldn't be able to tell, if the device has been rooted, also you do know that Sony have a guide on there website on how to unlock the boot loader ? Here check it out http://developer.sonymobile.com/services/unlock-bootloader/

I know about that website. That's how i unlock every sony i come across that needs unlocking :laugh:
But it also says if the "Bootloader unlock allowed" is NO in service menu, then there is no hope for unlocking the bootloader. At least not officially.. until someone comes with a solution for that..
So i managed to get some extra details on that problem.
Apparently i can't get LTE signal anywhere. And when i get LTE, connection automatically drops.
Could it be that the LTE chip is faulty? Does that mean that i'll probably get another device... because somehow i doubt that theyll try to replace the motherboard
OK, So I purchased this LG Treasure about a month ago and of course. I'd like to root it, Problem is Tracfone has this thing locked down tight. the bootloader/Recovery is not accessable. If you do the volume down/power button combo, it only brings you to a Factory date rest option. . I went to LG support and had a chat with them. I was informed by the tech that the bootloader access has been disabled. I asked if there was a way to enable access and he said that there is a way but he is not allowed to tell me and suggested that i come here to inquire. So i am hoping some here might be able to help, I don't even care if brick this device , it's worthless as is. Adb will see the device but fastboot will not leading me to think it's disabled by the carrier as the tech suggested. So any help would be greatly appreciated. Some one please point me in the right direction with anything i can try . Thanks All.
thank you..

Thank you so much for posting this question as I have that same issue. Your question was well put. Yet no one has responded. I hope there is a solution to this issue. :good:
these questions regarding the rooting of the lg treasure, which is my phone ironically, brings us to 1 definate answer, and that is that tf already knows how to unlock the bootloader, and thus, root the phone. it seems logical if any other tf/st phone has a similar os/locked bootloader that has been rooted, we might try those, or find someone recently seperated from the employment of tf who may spill the beans perse. just my input.

Thank you for giving me some hope lol. But still I have had no luck rooting this phone. Pretty aggravating. It's a decent phone and all. Sad they ruin it by locking it.
oem unlock
Did you first go and turn on oem unlock in the developers section of the phone? It is required by many phones under loli to unlock the bootloader. Might need to turn on usb debugging too in order for fastboot to be able to access the bootloader to get root on the phone.
My OEM unlock option has been enabled. However I have had no luck at all rooting this phone. It's unfortunate. Again I'm asking any developers available to please work on this project. The LG treasure is a very popular phone. Not only because of the price, But the features the phone has. Please I have done my best getting this phone to root.. But I'm out of ideas.
I have the lg rebel 2 lte and same problem. There is of course a way, their official unlocking policy is they'll grant us the unlock after a year of service paid. So they charge you for the device then charge you for a whole year for full access to said device. $$$
But lg has an official developer thing now where they'll email you the unlock.bin file to unlock it.
However the only; and I can't stress this enough, the ONLY problem is they've coded the bootloader to skip fastboot entirely. Somewhere between the first and second splash screen the bootloader and fastboot are working, soon as it shows the tracfone logo that's when you know its booting android. I have yet to figure out how to read the logs of the boot process to see how.
Yes, enable oem unlock and usb debugging.
However everyone with a new lg phone under any of the tracfone subsidiaries will find that those options don't matter. There must be a dialer code for the bootloader deal.
This is a problem, and it's doing my nut. I have a Vodafone Smart Mini 7, which I desperately want to root, to get all of Google's bloatware and the stuff the original network provider put on it.
I've already unlocked it to all networks, but the bootloader is being a PITA. I've done the usual with adb and fastboot, namely put it into USB Debugging, and then done this;
Code:
adb devices
adb reboot bootloader
fastboot getvar all
When I get to the section on the bootloader, it advises me that it's Secure.
I tried to use
Code:
fastboot oem unlock
and when I confirm on the phone that I want to unlock it, I get told that Remote Unlock is not allowed.
I assume that the fact that fastboot getvar all says that the bootloader is secure, means I need some sort of key to get it off. My old network provider don't know where to get it from, my tech team don't know where to get it from and I'm screwed.
Anyone got any ideas on whether I can get round the "secure" part of this, like some way of finding the key for it? Thanks

I have the exact same issue I read some threads and nothing solid has come out of it some say they managed to get root but others say they bricked the phone
Any news on this topic? I too have one i desperately would like to root because it is permanently full and you cant do anything wih it. The Google apps and the apps installed by my service provider take up all the onboard storage space. I downloaded only Whatsapp and Facebook Lite and bam,the phone is completely full and useless as it cant do updates,runs extremely slow and does all sorts of random stuff like restarting on its own etc. driving me utterly insane.
This is the first Huawei device I own and I was wondering, what are the consequences of unlocking the bootloader?
Would DRM be lost forever like in Sony Xperia phones?
And if they are lost, does any software on stock Huawei android OS stop working?
Please give as much detail as possible in your answers since I do not want to mess up my new phone.
Unlocking the bootloader permits you to modify entirely the system.
However it comes up that he puts you an annoying message saying that "this device cannot be trusted" EVERYTIME you restart your phone.
Even when you go to your stock or TWRP recovery, it always says this.
When you're rooted and you decide to relock your bootloader, it'll tell that your device is modified so it failed verification... so it's another message in your face !
You'll lose warranty it seems, you'll lose all your data, and DRM might be deleted too (due to the "factory reset lowlevel")
But there are no losses in functionality like on Sony devices. So in general, if you know what you're doing you won't run up against any problems.
Hi there,
So I am a bit confused, but mostly I am curious... So I have a Sony Xperia Z4 Tablet (SGP771), I bought it off ebay pre-owned and for awhile I have been curious about rooting this device (mainly to block ads and remove unwanted and unremoveable content [ie Facebook] whilst still using stock android, but rooted). But for awhile now I have known that my device in the service\configuration menu has said 'Bootloader Unlock Allow: No' which has excluded me from what feels like everything available in terms of modifying the system to actually be rooted. The device is network locked to O2 UK, which I also assume the device is network restricted in relation to the bootloader also.
So I am confused because some threads have said about unlocking a locked bootloader, whilst most have clearly stated that their modification is not for my device (After having the bad bootloader message after all). So my question is, could someone tell me what actually is available (If anything at all) For me to root this device?
What I have learnt so far is that if I want to change the 'Bootloader Unlock Allowed: No' I would have to switch the motherboard with another one (Which is clearly an extremely expensive process and not something I would want to do). Other than that I would have to wait for an exploit, But I am not sure if there is one available (Yet?) which brings me to my earlier question. Otherwise I would have to continue to use the unrooted stock android, which I dont really have any issue with because I would definitely still root it and use stock if that was available to me (Blasted bootloader rejection).
I would really apprechiate a response on this and thanks for reading XD
I would contact o2 and see if they can help.
Maybe SONY (doubt they will do it) or a SONY repair center (third party).
Replacing the bootloader should be doable in software.
No solution to Xperia Z4 Tablet Locked Bootloader
Hello, I got the same model locked to O2 UK as well and as far as I know there's still no solution to that problem, ie changing the rooting status to YES or rooting the device on a locked bootloader like we all rooted previous Xperia devices. O2 requested Sony to lock the bootloader on purpose. There are many reasons for this. One of them is, O2 doesn't want anyone to change the IMEI of their device if it gets blacklisted, for example. Of course Sony (Service Centre) can unlock it but I doubt we find a Sony member of staff who will risk losing their job for doing so. However, there's a way of uninstalling unwanted apps (bloatware) without root, but this method uninstalls the bloatware for the current user only. So basically if you have several user accounts, you'll have to uninstall those apps as many times, and also keep in mind that the operation is not reversible. So the only way to restore those apps is by factory-resetting the tablet which leads to wiping all the user-data. That method is done via a PC and you need to install, I think, Android SDK as well as Sony drivers. The full guide can be found here
https://www.xda-developers.com/uninstall-carrier-oem-bloatware-without-root-access/
Again, this is not reversible unless you factory-reset the tablet.
If I ever find a solution, or a renegade Sony guy lol, I'll let you know.
