I just bought a Z3CT(SGP612) and am a bit confused.
The first big question is about DRM key thing. Why do I care about them if I don't have any other Sony devices (Playstation etc.) and probably won't ever. I read in one thread that these keys may be non-recoverable, but in another thread it was said they could be saved and restored. What are the best practices for doing this?
Second, and I'm stuck here until this thread works, or further research surfaces the answer. I just bought this unit, it's brand new out of box. I'm probably the last man on earth to buy one, but....The device is nagging me to update, but I think that may end in tears. I'm afraid Sony official updates may render the device unrootable, or permanently lock the bootloader forcing me to beg Sony to do whatever I want to my own device. I think on 4.4.4 there is a way to unlock the bootloader without begging Sony to do it. The device is presently 4.4.4, build 23.0.1.A.0.167. The nagging update will take me to 23.0.1.A.3.12. I'm assuming there may be further updates beyond that to get to 23.4.xxxx. Should I accept this, and do any other updates, or proceed directly to one of the pre-rooted stock ftf files (sorry, what is ftf and acronym for?). I'd like to get to the latest 5.11 and have the ability to run adaway, make backups, have proper working SD card and USB OTG, and maybe run a few Xposed apps all of which mean I need root. As it's a virgin device I don't care about if I have to wipe the device in the process.

as i´m in the same situation as you i will share my experience / research so far:
1. Rooting works on different firmware with different methods, kingroot being one rather easy but with the drawback of sending personal phone data to uncertain chinese servers. Rooting 4.4 seems easier than 5.x.
2. Research showed that the DRM keys / TA partition is something to be backed up, just in case. But for backing up you need root but no unlocked bootloader (unlocking erases the keys).
3. Recoveries can be installed without unlocking the bootloader but need root(?).
This is where im right now with my progress - rooted, TA/DRM keys backed up and on a custom recovery but bootloader still locked and TA intact .. getting root demanded some patience and several tries though.
4. next step will be installing a prerooted 5.1 firmware i guess and everything has to be running fine
Hi Everyone,
Wanted to know if anyone has already figured out or through a different method, can help me root my phone.
It's an LG phone under GSM technology by TracFone for Walmart Straight Talk service. the Model is "LG l21g" or "lgl21g".
It is specifically running Android 5.0.1
I've learned it's better to follow a root process specifically made for the exact model of your phone. But since TracFones lack much in rooting fame, I'm hoping that there is a safe method used to provide basic root access to phones/devices that have the respective OS. For which in my case is version 5.0.1
I am new to rooting but not computers in general. I have searched for quite a while for a way to root my device by model. I've found nothing, and AndroidArea51 seemed to have a little success, but are not sharing a clear tutorial sadly. But I am skeptical about 1 click root apps and how they may tend root the device for a few months before unrooting automatically and then forcing the device owner to pay to root again. You know, the old regular malicious hijacking software you can't get rid of without a hard reset or what not.
I am also aware of locked bootloaders but am not sure of what it means for my request to root. Should i unlock mine if it is locked in order to root? Or is it unnecessary unless i want to flash a new rom onto my device? I've obviously read things online, but am still learning the relationships of all these things
I greatly appreciate all your time and help in anyway you can.
Thanks.
I used kingroot for a successful root on my LG destiny. Im hoping for recovery and roms soon but I don't know if any devs are intersted in our phone.

hey Failbringer60,
Hope your holidays were great and thanks for your comment. I am very skeptical of software such as kingroot and iroot and others of the same nature that are usually one-click root types. Though i'm not against using it if it's the only way to root less popular devices such as ours, i would rather have a little tutorial/guide on how to use the app/software to root the device then get rid of that app and its bloatware (and any other malicious ware that comes from it) and sustain a more honest or reliable superuser app/access to more precisely control the permissions that apps from the app store demand before download and use.
I have seen in other forums where users find that these one-click root apps aren't so trustworthy after a few months, and the device doesn't adhere to them as it did before. It's these kinds of things that sort of scare me. but if you are aware of a way to use these apps to gain root access and then a way to get rid of them while keeping root on my device safely, I would be more than glad to learn.
I am very new to rooting android devices since i've never done it before. and am trying to use my knowlegde from some PC maintenince to understand these things. so i hope that you can excuse me for not fully understand some things. But i am open to any help that can be spared.
Thanks in advance
hi
try kingroot on playmarket it worked in my tablert, only takes some minutes if you are lucky
Thanks.

Thanks, I hope your holidays were great as well. I understand your reasoning for concern. I haven't been able to successfully use supersu to handle root operations. Busybox will not install correctly either for me. I have successfully achieved root access though through kingroot. I don't remember the version I used but it has been rooted for well over 2 months with zero issues. I have replaced my bootanimations without bootloops as well.
I am currently trying to romdump and pull device tree to see if I can get a KDZ created or ported. As I am trying to get twrp recovery installed. And I think the only way for that to happen is to get to 5.1. But to answer any doubt. My experience with kingroot has been okay. Also rootchecker apps confirm root as well.

Thanks for your reply. I apologize for not being able to understand all the technical jargon when it comes to the android platform, but as i ask questions, i can pick up on it fairly quickly.
For now i take it that you are still figuring out a way to backup your android system, since the only offer the LG Destiny has, is to back up your data to google cloud. It seems that either tracfone devices took that ability away (since i think that any computer like device should have a recovery system - though i could be wrong) or it is a flaw in android 5.0.1 which is what our devices are running.
I take it that you are "romdump"-ing to kinda like create a clone in a storage space which you can turn into a recovery rom in case the device messes up - i think.
I'm glad to hear that Kingroot worked for you. I would like to try it too but i would first love to back up my system entirely so that if a noob like me does mess up, i haven't completely lost everything.
Can i ask you if you are able to delete/uninstall bloatware from your Destiny now that you have it rooted. But you say that you are not able to install supersu (which i assume is software that lets you control your device with admin rights)? Reading things online, i've come to see that kingroot has a supersu type of software, but that it's inferior or malicous or something, hence why people are trying to install supersu in replacement. I may be missing some facts there, but i'm always see a relationship between the two.
Would you lose your root access, or ability to remove bloatware and control other app permissions if you removed kingroot? Or is it supersu that retains the root access that kingroot achieved, but people are ridding their devices of kingroot because kingroot inevitably introduces its own bloatware at the price of a rooted device?
Sorry to sound all over the place. I've just seen a consistent connection between kingroot and supersu online everywhere i look. I've never seen how either of these apps work on a device once installed, but i do know that people are always using supersu right after using kingroot.
Exactly, for the LG leon user they got the update to 5.1 which enabled them to unlock the bootloader and flash a custom recovery for the ability to back up the rom. As for us Destiny users I think we aren't going to ever get anything but root for a while. And yes kingroot does install its own bloat ware. And I have removed all the stock bloatware that came with my phone.

Hi Failbringer60,
Were you able to somehow successfully backup your Destiny's rom to use as a recovery source? I myself just went through a whole lot of folly and have practically lost my device. I believe my spoiled Destiny is soft-bricked. It will not boot past the LG logo screen. I don't think it's looping since it doesn't fade to black and return repetitively. It's just frozen on that screen. Now i'm diving deep and reading a whole lot more about such problems and solutions, and am learning much more. But sadly, the design Tracfone has left the Destiny (and most likely it's other android models alike) is quite handicapped. I've come to understand that there is absolutely no boot menu with particular options you'd normally find in flagship models, and recovery only works if, well, if the device still works (as far as i've tried everything i know). Part of that recovery would make sense if content was the only concern. Though any system based malfunction is merely a complete loss. I have yet to download and try a few pc applications that others use to connect to their android devices. But since needing exact phone/model firmware or system image backup to fix many android issues are what these pc applications use, and LG having completely omitted the lgl21g model from all their lists on their site (except for the product landing page of course), I have no idea how it would help my situation. For all I've said, i may stand corrected, since i have yet to attempt the revival of my device.
So i hope no one gets annoyed when i ask weird questions, but i'll do what i can and document my findings. If you or anyone else may know how to help me, I would very much appreciate it. If you need more info from me. let me know.
Thanks.
Hello everyone,
Right now I have another thread for the root over ADB with DirtySanta, I've that far. I have a potential method but I need more information on it from somebody else so I am waiting on a response from him, once i have that I'll work on it. If you guys have any other potential ideas that'd be great.
Thanks,
Abine45
This is my link to the root on ADB. I will be updating it tonight or tomorrow for the convenience of others. Thanks for waiting.
http://forum.xda-developers.com/verizon-lg-v10/general/temporary-root-adb-t3523538
NEW INFORMATION FOUND! I GOT SIGNIFICANT ROOT ACCESS WITH DIRTYSANTA!!!
SO i used the DirtySanta fearing for my life I wouldn't ruin my device, well the v10 failed it. rebooted and it didn't do anything but reboot back into the normal bootloader and stuff. But what i found is that he go the dirty cow to just work under root, so maybe from there we could do something, anybody have any ideas?
people care but it seems kind of like you expect people who have no clue to do any of this to assist. Hence the reason they are willing to pay a rather large sum of money for a bounty.
1. You cannot repackage a TOT file, well you can but, because it is digitally signed so that the locked boot loader will recognize it and allow it access to image the system. Repacking a rooted version on MM or Nougat will brick the phone if it is not digitally signed by LG.
2. You can pull a copy of the boot image with dirty cow but you can do that from the TOT or KDZ. You cannot put a new one in with dirty cow with out bricking the phone.
3. Most likely not. SELINUX policies combined with updates and fixes have removed most of the previous exploits.
4. Nothing personal but if you are asking us where the boot image resides... that does not inspire anyone here to give you a hand. You need to be in the android devs forum asking these questions.

How did Tungkick manage to repackage it then? The dirty cow exploit can exchange recovery though on an unlocked bootloader so shouldn't I be able to replace the boot image if done correctly wouldn't it work? I could possibly unpack everything and modify it all and test it but the issue comes back to repacking and flashing?
Ask him, but if you attempt to do this on a locked and encrypted boot loader then you will brick the phone. I mean think about it, if it was really just that simple every phone would be rooted and rom'd. Most phones running 6 or above have had the security vastly increased to make the phone secure so they can be used by government employees. Hence the introduction to SELINUX polices into the kernel which is why getting root is so unbelievably difficult. The locked boot loader resets everything at boot so getting root and maintaining is so hard combined with SELINUX does not allow standard root to perm. write anything to the system partition and then good old hboot kills anything you did mange to write on reboot... you can start to see how difficult this really is.
Tungkick did this on 5.1 Lollipop not 6.0 Marshmallow. The above mentioned difficulties with increased SELunix security plus 6.0 and up requires systemless root.
Still would love to know why no dev will go near this Phone. Does XDA have some deal with LG to not hack their phones? Very fishy why every dev avoids this device like it has the plague.

LG are just not popular devices for hacking due to they make if extremely difficult. LG is a Corp. friendly company it is why Verizon loves them where companies like HTC are a bit more user sympathetic.
Funny you say that

Funny you say that! Tungick said to me, and i quote "[email protected]#$g you" and blocked me from Facebook. He also told me that he wouldn't tell me because it's a secret. He didn't speak very great English, that's why there is an ing at the end of the F-bomb. I asked Jcase through XDA and he said he wouldn't and so i put it better explanation of help through an email and he said I was harassing him... In which case before hand he said he doesn't develop for LG because he says basically we are A-holes sadly and that we don't live up to our donation pledges.
That's what I'm saying though. It's like no dev will go anywhere near an LG device, at least the newer ones anyway.
They can't be much harder to crack than Samsung and those are getting cracked.
The person who rooted 5.1 on V10 basically tells you to F off. Yeah there is nothing odd about that.

True, that's why I'm going to try to do it. If you know anything and want to help could use it.
Wish I could help. All I know here is you need systemless root on 6.0+. This has nothing to do with the v10 in particular. Systemless root should work on all devices 6.0+. It has already been achieved on the Galaxy s7 and it has locked bootloader. I don't see any reason why this can't work on the v10.
I just installed Linux on my computer gonna try somethings this weekend... We need to keep in touch

Anybody can help! Do some research and send it and whatever you would like to do. Try different things, Try to modify bits of code and see what you can do! Always gotta start somewhere!
Modify code? You just went way above my head. I know about root, certainly don't know how to achieve it. That's why I count on the folks at XDA. I only have one v10, can't afford to brick it. Plus I already have root on 5.1.1 and I heard that 6.0 causes this phone to have problems.
Many, many v10's were offered up in order to attain root. Not one was taken by any dev. Maybe you can still get your hands on one of those.
You need to find someone that knows about systemless root. Without that you aren't getting anywhere.

The thing with that is the fact that even if I know how systemless root works, I still have no way to install it, so first I need to find a way to get in the system.
Think I might have a way though
From what I understand systemless root will modify the boot image to attain root. Super SU will decide how to flash based on firmware version. Will automatically root normal with Lollipop and down, will automatically modify boot image on Marshmallow and up. How you will be able to modify the boot image on a VS990 without bricking it I don't know.
In order to do system less root we need a unlocked bootloader... It says that everywhere I'm reading
Hi abine45,
Please read this post completely, the guys here are close to obtain the perma root on android 6, using dirty cow.

Hello,
i know there is plenty of this kind of threads. But i really need simple guideline , already tested way to root this device. I have rooted couple phones, (note3, sonyz3, galaxy s4, etc), but never this model before, or any model where i have to touch the bootlocker.
So, this is now new to me and looks like there is too many way to do that, and it´s confusing. This girls is on fire, at least my brain are
The phone is my 12 years daughters phone, and my son has also this phone, and the internal memory is straight from a...
So i assume, only way to solve this is root the phone and use the external memory as internal memory, right?
And what about this, have you tried this, is it valid way ?
(Tried to put url, but i am newbie, so i can´t, but what i ment is one click root, is it even possible)?
Anyway, can someone please give me a hand and tell me easiest way. The way which working and tested
I´ll appreciate this very much.
Have a nice monday all of you.

this is a good tutorial https://forum.xda-developers.com/m4-aqua/general/guide-unlock-bootloader-twrp-touch-t3247939 for unlocking bootloader and flashing recovery
but rooting with an old version of su, you need to search for the newer su version, and beware, do not update su from Play Store
one more thing, you didn't mention Android version of your devices, settings-> about phone
for root you need a specific way for Android version Lollipop or Marshmallow
Im interested in picking this phone up but my main holdback is whether or not you can root it. Ive been living that root based adblock life and I cant go back. Non-root based adblocks just dont work as well as the rooted ones.
Has anyone rooted the phone? does magisk + adb flash work? Has anyone rooted CN phone with global rom?
You should be able to but I would be cautious.
Firstly, the service for unlocking the bootloader seems unreliable from some reports (apparently you need to use some Chinese portal for requesting an unlock file - if you don't have luck getting that or it doesn't work, you're stuck and I bet getting help from Lenovo is not easy). Secondly, unless I've missed something, I don't see proper official ROM image downloads from Lenovo for extracting/patching boot or safely reflashing the device from bootloop/soft brick, so you have to go with whatever is available around for download here or elsewhere on the net and hope for the best. Even more important since you don't have custom recovery options (like TWRP) on this device.
In summary, yes, but it looks like risky business. This device doesn't seem to be root friendly...
