Hi all,
So I'm considering buying this device. But I do have a question about it.
Hopefully this isn't a stupid question. But does unlocking the bootloader on this device, thus permanently removing the DM partition (Unless you back it up), disable some functionality that would otherwise be provided with the stock firmware? Like image rendering... etc
I only ask because a long while ago I read an article stating that Sony are relaxing their stance, making their devices more open to custom firmware being installed on their devices. I checked the Sony Mobile website, on the "Current platform functionality" page (Where it details the quality reductions in hardware by choosing custom firmware over stock, in the list of devices) and this device isn't on it.
So, is this device not restricted in terms of hardware by Sony through choosing the install custom firmware?

Hi all,
What is the mechanism that Android uses to update phones?
In case it is Manufacturer specific, both my phones are Sony.
However my new M5 does not yet have a custom recovery so it is not as easy as my previous phone to just load a fully built OS.
My undertstanding of the general path is:
1) Android release an update
2) Manu customises that
3) Network operator customises that again and maybe adds bloatware
If you CHANGE networks, does that break your update path, or do you continue to get updates, but from the original network who provided you the locked phone, which is now unlocked?
Any thoughts on this?
If my question is not clear happy to re-phrase any confusing parts.
Hi all. I'm a complete newb and don't even know the correct terminology to use. If I should not be posting this here maybe someone could point to the right place for me to post. Here is my issue/question: I have a Moto E (the second generation model, aka Moto E 2015) and it is the LTE version - the XT1527. I bought it used and it had originally been an ATT phone. I went to the ATT website and got from them a code to unlock the phone so I could use it with my provider (Ultramobile, an MVNO that uses T-Mobile's infrastructure). It's a pretty basic phone and pretty slow. I have removed all the ATT-branded apps I can but there is still plenty left. What I am wondering is: Could I somehow load what I think is called firmware so that the phone was like the versions actually sold by Motorola? I figure the less branded crap on it, the more space I will have for my own apps and perhaps it may even be a little faster. I have read quite a lot of posts on this forum and it seems to be quite hard to do because ATT phones do not have unlockable bootloaders (and I don't even know really what that is yet). But when I go into developer options on the phone there is an option called "OEM unlocking" that has, as a subtitle, "Allow the bootloader to be unlocked". It is currently switched off, but it does allow me to turn it on if I want to. It gives me some sort of warning about "Device protection features will not work while this setting is turned on" but that doesn't sound too scary (although I am of course totally ignorant and could be totally wrong about that). But does this mean that on this phone if I unlock the bootloader, I could load the original Motorola firmware/ROM once I learn how to do it?
Thanks for any help.
Dan
P.s. this would sort of be a learning experience. I have another phone I would use while I try to play with the Moto E.
I actually didn't see the part where you said ATT can't have the boot loader unlocked my bad, you can still check using the Motorola site I guess but yeah you can't change the ROM unless you can unlock the bootloader
So the first thing you should do is unlock your boot loader
Note: this will wipe all the data on your phone so back it up before hand
https://forum.xda-developers.com/moto-e-2015/general/guide-unlock-bootloader-moto-e-2015-t3045748
Then I would actually suggest that you change to Lineage OS instead. The Motorola stock ROMs are no longer being updated with security updates AFAIK and you are stuck on marshmallow (android 6). Lineage OS has all the security updates and is on nougat (android 7)
To do that first you would flash a custom recovery (TWRP)
https://forum.xda-developers.com/mo.../twrp-squid-twrp-recovery-moto-e-lte-t3137649
Then you can find our official Lineage OS here https://forum.xda-developers.com/mo...ment/rom-cyanogenmod-14-1-moto-e-lte-t3516694
Thanks but you have not addressed the main point of my post, which was whether my phone's bootlocker is or is not unlocked. Also, I am not interested in anything other than stock ROMs and I prefer Marshmallow (or better yet Lollipop). Definitely don't want Nougat.
I have this phone to, I have a question, this device exists possibly to unlock bootloader and put any custom rom? I can't find tread with this info
Hello all,
As a frequent user to the XDA Forums but a first-time poster, please allow me, from the onset, to express my gratitude for the litany of assistance this forum has offered. The resources here and pure talent have proven invaluable; from assisting me in actually taking a Nokia Windows Phone and installing Android, bypassing Google's FRP on an LG Tablet to mirroring a broken display and thus saving my S5 Neo. Please accept my humble thanks and heartfelt gratitude. Perhaps one day, I will be able to offer something back to this amazing community. Kindly bear with me as I need to ask you all for some expertise and guidance one again — I have some specific questions — as a segue into the first inquiry, pardon me if this is the wrong subforum.
Question the first. And you have my permission to all point and laugh at me for asking this one: Is this subforum dedicated to a device with a specific label of LG G Pad X 8.0 or is X expressive of a variable employing categorization of many devices? I know how to research, but I still can't find a direct answer or mere suggestion; deduction implies the latter. Specifically, I am enquiring about the LG G Pad III 8.0 FHD (the LG-V522). I do hope X was a prelude to "insert Roman numeral here" or now I just sound like a verbose moron with too much time on his hands.
Background & Specifics:
- Google FRP was bypassed and a clean, stock installation of Andriod 7.0 Nougat was employed.
- While this tablet was originally sold with Marshmellow 6.0.1, support for OTA updates extended to upgrading to Nougat which became accessible upon the successful factory reset after bypassing Google's FRP.
- This tablet is not rooted.
- According to LG and LG's Developer Blog, the V522 bootloader is not unlockable.
- This tablet does employ a SIM card slot and I've been using an active cellphone SIM (and of course, WiFi where available), but apparently the tablet is only utilizing the data component of the Rogers Share Everything plan and when I dial my own number from a third-party phone, it goes straight to voicemail. Yet sending texts to my number will pop up as a notification just like any other smartphone.
- Tablet is "Canadian" and SIM-locked to the Rogers / Fido network.
Tablet Details:
- Android Version is 7.0 Nougat employing a security patch level dated December 1, 2016. Baseband version is MPSS.TA.1.0.c3.3-00015-8952_GEN_PACK-1.79167.2 and it's running a kernel v3.10.84-g22068de [email protected]@ ) #1 SMP PREEMPT Mon Dec 19 14:48:23 KST 2016. Its build number is NRD90U and it runs a software version V52220a. Firmware version is 7.0.
- Factory Version is specified as LGV522AT-01-V20a-302-720-DEC-19-2016-ARB00 with SW Original Version being specified as LGV522AT-00-V20a-RGS-CA-DEC-19-2016-ARB00.
- Apparently, this product is also categorized as "b3_rgs_ca". I have seen this label, almost to the point of a recurring motif, through my research, as simply referred to "B3".
- The LG "hidden menu" is accessible by dialling *#546368#*522# via the Google Hangouts "Contacts" app.
- "Download Mode" is accessible through ADB commands and respective key-combinations and I have been able to reload or "flash" V52220a more than I'd care to admit.
Questions:
- Since the bootloader is apparently "unlockable" by official standards, does this explain why even through ADB I cannot get the tablet to boot into the bootloader partition? I'm familiar with ADB, Fastboot and the Command Prompt and all respective drivers on my Windows 10 desktop are the most current and configured correctly and the step of enabling USB debugging, OEM unlock, et al has already been covered (unless you've got a completely random idea of some random setting I may have overlooked). Invoking the command "adb reboot recovery" triggers an entry into the stock recovery mode, but selecting from the menu "reboot into bootloader" merely restarts the device; as does invoking "adb reboot bootloader" from the command prompt.
- If "download mode" is supposed to be synonymous with fastboot or bootloader mode, why does the tablet not acknowledge any fastboot commands?
- Can or would anyone be kind enough to explain why there is such a diverse categorization of this tablet and what the specific nuances imply (i.e. model B3 vs. LG-V522 vs. LG G Pad X)? What is the meaning of V20a contained within the descriptors/identifier of SW Original or Factory version?
- Is it possible through an entirely unofficial method to root the tablet without unlocking the bootloader (some users have reported yes, but never when utilizing the "Canadian" version)?
- Employing "dirtycow" is no longer an option as the security patch installed precludes this possibility (unless there have been updates to the process of using a muddy heifer that I haven't found yet).
- If rooting is not possible at the moment (even through unofficial methods), is it still possible to establish and employ an "emulator" on the Stock OS to "trick" the tablet into thinking it has a built-in cellular modem? I've found several references that suggest this tablet does have a cellular modem because of the SIM card, but when I try and look at the tablet's hardware on the actual device, telephony information is lacking.
Trying to unlock or hack the bootloader or even just rooting this tablet seems more like a beautiful woman slapping you for simply asking if it'd be okay to buy her a drink — yes, you want her to give you full root access — but hey, you're being a gentleman and trying to wine and dine her first (I know I'm a nerd and it has been awhile, but I digress).

FRP reset on the LG-V522
Hi Carvio,
I haven't been able to perform an FRP reset on my LG Gpad3 LG-V522. I didn't want to use the device on the cellular network just as a tablet at home.
I ended up buying the Octoplus FRP reset dongle but it turns out to not have the correct model in the setup.
How did you manage to bypass the FRP rest or rest it on this tablet?
I think Chimera may have a tool to do the reset but that means another $100 to unlock the tablet...
Thanks in advance,
REDRONAN.

i tried to frp myself and i got it in qualcomm 9008 mode. can you make a backup of your device?
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.
