[Completed] Finally got my SM-T217a running 4.4.2 rooted - XDA Assist

But because for so long the bootloader seemed unlockable, and because when they finally did get it unlocked, it was with a device that was almost 200$, there was a complete lack of development on this particular device once it was given the 4.4.2 upgrade. Over the course of a year, I have found many things about the tablet that I have been unable to find out on my own to get into.
I found that the tab 3 lte was actually designed as a really big phone, but the dialer, phone and dialer storage were blocked by AT&T, so even with a sim chip, the tablet just will not function as a phone without getting a VOIP app, and I really shouldnt have to considering that I have a perfectly good phablet capable of actual phone calls. I dont know how to use terminal emulator very well, or if the language changes drastically between versions of Android.
I was also wondering if it was actually possible to unlock the bootloader from Terminal emulator now that I have full root.
Is there a way of finding out if my current stock rom is one of those that have the SO- attached to the system folders so that I cant write anything to the system folders without reverting to out of the box system restore. And lastly, I was wondering if there was ever any custom recovery that was made for this device that would be usable now, considering that when the device came out it was on Jellybean, not kitkat. If anyone could help me I would be greatly appreciative. I know it sounds like a lot of work for a tablet , but I am not exactly overflowing with money to go and buy a new one. This was a gift and I just want to try to avoid bricking it when I just now finally got the damned things rooted.

[Q] T-Mobile LG Optimus F3 Forum?

Okay, so I know this phone doesn't exactly win the spec war, but it's awesome and would make a fantastic rooted phone. Unfortunately there isn't a forum here on XDA for the device (either because it's too new or there isn't a demand for it)
Do you guys think a forum will be made for this device? It'd be nice to at least have a place to say what root methods DON'T work (I've tried a few)
Thanks for the help, XDA rules!
I second this. I am planning on buying a new phone and after researching numerous phones out there based on my tastes and constraints, I think this phone works very well (another is Samsung Galaxy Exhibit 2). One flaw that I heard is the amount of storage in this phone is around 4gb. Without a way to put apps on an external SD card (which I believe would require a custom ROM), the storage would probably fill up pretty quickly. So it'll be great if XDA opened a forum for this phone.
As a side note if anyone can point to other devices that fit my needs I would be grateful:
- Less than 4.2" screen (preferably 4").
- Android only
I don't have any financial constraints or any favorite companies.
Thanks!
What root method did you find worked? Did you try framaroot? Also have you found any Roms?

Bad news
I have created the recovery tree, and have created a recovery.img for this phone. ok now heres the bad news OUR lg optimus f3 has a stock 3.4 kernel with a locked bootloader. Even worse news is that 3.4 "locking" features a sha5 hash system for its image/partitions (recovery, boot, and bootloader). Even worse news there is no known (or atleast what i know or have heard) way to get around this. The phone will be forever locked until lg updates or allows said lock to be removed. I have flashed the recovery and have had no damage to my device but it just sticks at "unsecure recovery" and does a hard reset (factory restore) every time i try to play with it which is a huge flaw if you ask me.
I have hexedited the bootloader and found that there is indeed "juicy" strings within that may tell to a future unlock these strings being
-Device UnLock!, so Boot Success!!
-oem unlock
-ERROR: Could not do normal boot. Reverting to fastboot mode
Also these strings could just be defualt with all lg bootloaders meaning....there is no hope.
My phone is without a soul and I will never be buy lg again.
If anyone is able to get into fastboot
1. PM ME
2. run : fastboot oem unlock
Again root for this phone works great as long as you dont touch recovery, bootloader, or boot partitions

I've seen confirmations on three carriers (can't remember which ones off the top of my head, sorry [edit-well, T-Mobile and Virgin Mobile come to mind now]), so I'd assume the answer is yes. Regardless, I have yet to see anyone complain about adverse affects, so no reason not to try (though, grain of salt—I'm brand new to android).

BAHAHA me to man i think im down to 10 days. Im trying to get some attention but i need someone who knows little endian, and their way around bootloaders. Id be willing to donate to someone who can help me out, also to support the other 3 variants (if the aboot differs).
I have a recovery created also and a device tree (needs gpio support for kernel).
And to awnser your question, yes loki will work IF i can get the needed values so that when recovery/boot is read into memory that it overwrites the security check feature in aboot. If the wrong values are give you may end up with a brick (very slim chance)
My return window just closed . If it helps, you can pull the open source from LG's website and merge it with the android source. I also discovered an even easier solution: set up the LG Sync application, and select the "upgrade recovery option". Then, when it begins downloading, remove your phone, set Windows (or your relevant OS) to show hidden files and folders, and go the the Program Data folder. There should be something like "PHONEAX" under the LG Electronics folder that will contain the full stock kdz file when the download is complete.
It's really kind of surprising that there's absolutely no dev love out there for the F3. I suppose it's because the phone is entry level, but it's really not that bad but for the storage. I got it as a gift, so no complaints here—of course, if anyone wants to donate a Note or Galaxy gratis, I suppose I'd be willing to switch .
I had a Galaxy S4 from Verizon. I switched to T-Mobile Because believe it or not the network is stronger where I work. Also, there pricing on plans cannot be beat. But, I digress. The Galaxy S4 being a Verizon device never really functioned the way it was supposed to on T-Mobiles network. It was unlocked however was still useless for 4G LTE and while I could do better than edge in some places, those places were few and far between. I started to assess what it is I actually used my phone for these days. I'm not into modding with custom ROMS and kernels anymore and I'm not much of a multi-tasker either so I decided that I did not need the super power device anymore. The specs on this phone are perfect for what I need my phone to do. Its been a long time since I have gone beyond rooting to remove bloat and tether. I agree that the storage on this sucks. I don't understand why there are any devices anymore that come with less than 32gb internal. storage is the cheapest thing that can be added to a device and its not as though it uses much physical space. other than the storage I will say that I am impressed with the quality of this device and I don't know that I would even put this as low as "entry level device." I would say its more of a mid-grade device. I am also happy with the reception on this device and its nice to have a compact phone again that actually fits comfortably in my hand and on my belt.

No argument here. I like it well enough, but I'm (1) a closet geek; and (2) a heavy multitasker, so given the option I'd prefer something with more screen space (I just graduated from law school, so I do a lot of reading on the go). As a phone, however, you really couldn't ask for more—the size otherwise pretty much perfect, it's relatively snappy with most applications, and once debloated the stock launcher is pretty good.
That being said, the second I see a safe way to deal with the bootloader pop up, I'm diving in, no question .

Is the CAT S60 (Snapdragon 617) Rootable?

Morning all,
I have recently received my CAT S60 and I have to say, I am extremely pleased with the device out of the box. It is solid, extremely well built, battery life is amazing and camera quality is far better than the reviews led me to believe. Call quality is also the best I have ever had on any handset.
Unfortunately, I have never before owned a device without root. I have rooted most of my phones + installed a custom rom within a couple of days of opening the box. Sadly, this time round I've bought a less-popular device which is quite new and there is no existing support.
I am able to do most of the root-requiring functions with this phone (flashlight via button from locked, skip tracks with volume etc) using software workarounds, but I am already butting up against things that are pissing me off because I don't have system access, and I am so used to having it.
I've read horror stories about the lockdown function Qualcomm have applied to the 617 chips, but I now see that some phones with this chip have already been rooted (Motorola) so I am wondering, what are the chances that I will see root or a root exploit for this phone in the near future?
I'm not sure that I would sell the device over not being able to gain root, but it is really really annoying me.
I would be interested too. I couldnt even figure out how to set the s60 to downloadmode (If there is such a mode at all) to flash a custom recovery like twrp. Recoverymode is the usual volume up before poweron.

There is a switch in developer options to allow bootloader to be unlocked. Maybe this, combined with factory recovery menu will set us free? Flash a modified factory rom with root enabled? The stock ROM is very clean.

There is an option to unlock bootloader. It's called OEM unlocking
So, flicking this switch should unlock the bootloader???
That gives me a bit of hope for some development on this handset. None of the previous cat phones have seen any real development.

To be honest flicking that switch does nothing for me. I am unsure how to unlock the bootloader
On S60 bootloader is locked.
No fastboot, but you will be able to select recovery mode.
bump. I'd like to see this phone rooted.
Any progress on this or has anyone tried yet?
My SONY Z1C died on me the other day and I'd need to know if there's at least a chance to root this one.
I'm considering getting the S60 but only if I'm able to root it. An unrooted phone is barely usable to me...
Greetz and thanks in advance,

haven't tried rooting mine yet. Not felt the need to yet TBH
Mine is working pretty good without root. Only reason I'd want root honestly is to make backups, and perhaps uninstall a couple apps, but the bloatware is minimal.
Sent from my S60 using Tapatalk
Since the original question was "Is this rootable?" and lately answers have come in the form of "I haven't tried rooting mine" .... which doesn't seem much like an answer at all, to be honest .... I want to join the OP in asking this question. For those of us who have grown accustomed to the freedom and flexibility of having root access to our devices, it would be really nice to know (before making a decision to purchase) whether it is possible to obtain root on the CAT S60.
Does anyone know where to get a zip of the ROM?
After the Arstechnica review this may be my next phone. However, I really require a way to root it so that I can use iptables.
Anyone had any luck?

I tried contacting support about help to root, got the above back. It's a work phone so maybe it's better that I don't mess with it.
If anyone is going to root or make a custom recovery, it'll need to be without any support from the manufacturer. I mostly miss Xposed Framework for adblocking, less frequent notifications and the ability to longpress the back key to enable/disable screen rotation, the ROM itself is 99% "stock" otherwise and I have no complaints on that front.

This is, of course, their right, and buyer beware if you wanted a rootable phone. Still, I can't keep from being annoyed at this attitude; if I'm paying them good money for my devices, I want the freedom to do with it everything that I want, including modifying it and knowingly voiding my warranty, or even breaking it outright, if that's what makes me happy. Especially now that rooting/jailbreaking is a thing. Wanting to keep on controlling and limiting how people are able to use your product after you've sold it to them always sticks in my craw.
I guess I'll be passing on what otherwise looks like a perfect phone for me, unless some shining hero (or heroine) manages to figure out how to root a CAT S60 anyway, despite what the manufacturer might wish.

It is indeed a great phone, but the camera is sub-par. The focus takes an age compared to my Z5 Compact. I would wait for the second-generation version unless you critically need FLIR as a feature.
I've done a bit of poking around. I suspect that the bootloader could be unlocked with the commands "adb reboot bootloader" followed by "fastboot oem unlock-go".
I'm not going to do that at this point because without a custom ROM to flash there is no point in me voiding my warranty, but I believe it should be possible with USB debugging enabled, and the bootloader confirmed as unlockable.
I think this is how root will arrive on this device: by way of modifying a flashable ROM and flashing it to the device using QFIL as you would any other Qualcomm device.
The tools are all there in front of us, we just need someone with the knowledge to create that modified rom file....at this point I can't even find a factory rom to flash.
Given the recent speed and quality enhancements made available through the stock camera app, I also suspect that doing this will send us backwards to a much ****tier camera as has been the case with many sony handsets in the past.

Can someone un-brick an Alcatel 4060a for me?

I recently attempted to root my Alcatel 4060a. It did not go well.
There is a thread here on xda that explains in some detail how to root this phone, but unfortunately I didn't discover that thread until after my failed attempt. I used KingRoot followed by SuperSUMe. This actually seemed to work, and I definitely had root on the phone, but when I rebooted, it got stuck on the AT&T logo. Although it wouldn't go past the logo, I discovered I could still get a root shell on it via ADB. So, thinking I could fix it, I renamed the files in /system/xbin that appeared to have been put there by the rooting process (based on their timestamps) and rebooted again. This made things worse though: Now the phone won't even get to the AT&T logo, it stays stuck at the initial Alcatel logo now. I can still get a shell on the phone via ADB, but now I can no longer get a root shell, just a regular user shell. (And if I run the renamed su binary in /system/xbin now it gives me a new shell, but without elevated privileges.)
From what I've read here on the forums, there's no way to unlock the bootloader on this phone, and even if there was, there doesn't seem to be either a factory rom image or an aftermarket image readily available, so I can't use fastboot to flash it.
In another post someone said that there is an image for this phone available from boot-loader.com. I signed up on that site and looked around and sure enough they do seem to have an image for it. If I understand that site though, you must purchase one of their diagnostic/repair devices to use any of their images. Although that might do the trick, this is a < $50 phone, so it certainly wouldn't be worth it to me to spend more than that to fix it.
So my question is, does anyone here on the forums have one of these devices, and might be able to get this phone working for me again? I'd be happy to pay you for your time of course. Even though it's an inexpensive phone, money is money and I hate to just throw it away and start over.
Or, if anyone has any suggestions on how I might still be able to fix it myself without buying any hardware (or at least not any expensive hardware), I'd be happy for that as well!
It's frustrating because I've rooted every Android phone I've owned over the years and never had a problem before. Fail.
Thanks in advance!
Hi !
I saw your post here , doest it mean that you have fixed your issue ?
As an advice , before doing anything with any device , knowing that you have done rooting plenty of other devices , don`t proceed to anything until you have this basic stuffs around : a flashing tool and stock firmware .
Cheers !

No, I purchased a replacement phone. My comments in that other thread are referring to my replacement phone, which I was able to root without breaking this time. The original phone is still bricked. Fortunately this is an inexpensive phone ($30-$40), so I was able to replace it.
I'd still love to recover the bricked one though. It's not about the money, it just seems like such a waste to throw away a brand new phone just because it has bad software on it, even if it is a cheap one.

Oh, I know, and normally that is what I would have done. However this phone (even though it's rootable) has a locked bootloader. From all the research I've done, no one has discovered a way to unlock it yet, and no stock firmware seems to be available, except, as I mentioned in this thread, if you purchase a commercial flashing tool. That's not really an option for me since the costs of such tools are much higher than the price of this particular phone. That's why I was hoping to find someone here that has such a tool and would be willing to fix the phone for me for a reasonable price. I did find a shop that would do it for me locally, but they wanted close to $70. I could buy 2 or 3 of these phones for that price, so it wouldn't make sense to pay that much to repair it.
Do you know of any flashing tools that will work with this phone that are free or at least inexpensive? Since I have a second, identical, working, rooted phone now, perhaps there is some way I can pull the image off of that one to restore the first one?
Unfortunately no, I'm not aware of any kind of flashing tool for this device, also I don't think that just pulling a backup from a device and pushing it into another would work due to its locked bootloader.
If there is any paid flashing tool then there's is a reason why it's paid, the developer got probably some paid permissions from the manufacturer to use it and he wants the money back plus some extra, certain devices just can't be soft repaired without unlocked sources

Root for the ZTE Avid Trio (Z833) (MetroPCS)?

Okay, I know I don't post much in XDA, but I do read a LOT of threads!
The reason I am posting this is because I am wondering if anybody achieved root on this phone.
I have tried KingRoot, KingoRoot, OneClickRoot, none of those work.
It is running Android 6.0.1 Marshmallow.
I am about to screw around with ADB, see what I can do. I'll post back when I have got something.
Sorry if I posted this in the wrong section, I don't post much on XDA.
any luck?
I've tried every root method available without the PC and nothing. But, there maybe good news. In developers options there's a switch to unlock the bootloader. Now I'm no dev but I hope this makes cwm or tarp easy for devs to port and root.
I found https://mobile.twitter.com/srsroot/status/810325782417592325?lang=en srsroot claims it supports ZTE Z833. I've used srsroot once before but on another phone I have no PC so I can't test it but someone should test Cydia impactor see if it works.

1. I too saw that twitter SRSRoot business and tried it thinking, "Oh joy!" no, not working. Tried it every way you could (yes Kingo, KingRoot, vRoot, iRoot, FramaRoot, uRoot, & we-all_Root (the last two were jokes don't be so serious, nor was it a complete list of what I did actually try, ha!) too). I even wrote the people at SRSRoot telling them that it didn't work and have gone back to download their latest versions, still nada, zip, zero. FML on toast!
2. Cydia Impactor is not for Android devices, it is only for iOS. I went and double-checked just to make sure I wasn't trippin' thinking that maybe they have gone cross-platform. No, they have not.
3. I have the phone in question, I submitted a formal request on here in the best way I could find to get it added to the XDA devices list and I have been eagerly monitoring awaiting the day it happens. I was even considering trying to compile TWRP myself, but I just bought a different phone because I was tired of the headache. I couldn't figure out how to extract the zImage from it in order to give it a go (I think that's what it was). Anyways, I'm writing this before finishing reading the rest of the posts and may be rambling, but I had to respond. I have spent much time doing this. I ended up buying a different MetroPCS phone called the Samsung Galaxy On5 and was able to successfully root it and after much waiting finally got ahold of the Superstarz ROM that finally went out for that one. Just an FYI in case someone happens to see this before making the purchase. I will say that I feel like the ZTE Avid Trio Z833 has pretty good response time for such a cheap phone, then again they had a deal on it in the store, it looked to be more expensive at retail pricing. Anyhow, I digress, but felt the need to contribute rather than just lurk.
Oh, and another thing... The development option to OEM Unlock is "checkable", but as for actually booting to the bootloader it WILL NOT DO IT. The only way this is gonna happen to be rootable is if you use a custom recovery (which none exist yet) in a tar format and ODIN the friggin thing from download mode. So, there's your catch 22. If anyone knows how to extract the zImage and whatnot (without root obviously) I'd be more apt to give it a go and boot my happy bunghole into Linux and give compiling TWRP another go. I finally have had a lot of life stresses temporarily die down since I decided not to leave my current living situation and just stay with these irritating bastards another month at a higher rate. FML & Cheers!: good:
I should mention, however, that SRSRoot attempted to use it's "Exploit 8." So, I went digging into it's directories to see what the script was, but it was binary (and I didn't have reverse-engineering **** handy like PE-ID, and whatever else the kids are using in this newer age). So, I was like "wah-wah", but if any experienced ppl know more about the specific exploits that aren't ancient and actually working with Marshmallow that would be interesting to hear feedback about as well. Thanks. I really would like to use this second phone still, but right now I'm just using it as a Kodi/Megabox HD + AllCast Projector to watch streaming things without having to interrupt my working phone in the middle of it. It would also be cool to use as a straight VOIP phone with no cell service connected, but I've yet to find the free Google Voice VOIP loophole that is currently working. PM me if you know of these
P.P.S. I wrote another spicy post on hardr3set dot info about what crap I felt about their B.S. (weaksauce compared to anything legit which we all know you come to XDA for the meat-and-potatoes) because I was so tired of searching the Goog for root ZTE Avid Trio Z833 and having it be the top result over and over. Finally this has risen up. Thank you for starting this. Oh, and also, please... If you would kindly also request for this device to be added formally, maybe it would encourage development. Not sure how all that works, but yeah... power in numbers right?
Sincerely,
~Ye of little faith
Bump
are you telling me that faults advertising runs ramped all over the internet even Google play store and this is the nondoing phone ever made and it can't be jailbroke nor rooted
Rooting your zte device
Can not be done. This phone is an unfortunate accident by ZTE with numerous problems and they are not small issues but ones that affect the performance of the device. Replace that phone or your only adding to your daily stress.
That kingroot and oneclickroot don't work
For this phone
a
Guessing this is a dead issue? It's an okay phone but lags horribly when it comes to multi tasking
Hey I don't want the root thing to die on this topic. So would it be possible to root via ADB update in recovery mode? Or to somehow update via SD card and applying root? I refuse to give up hope on this device lol
Anyone made progress on this? I just got this phone and it definitely has some issues, but I feel like root would resolve most of them.
Has anyone figured out a way to root this device?
I've searched for a long time without success. I hope something comes up.
Any progress on this? Thanks
following, bought one this morning hoping to have a cheap rootable phone.
I got mine from MetroPCS for $29. lol Yes, it's frustrating and has got problems (I've already put two of them through my dashboard and had to replace them, within the first 2 months, but it only cost 30buck so WTH. Anyways, I decided after I destroyed #2 that I was only going to use it for work and add no apps to it, except maybe GasBuddy and Winamp. Other than that, it's stock and I haven't had any real problems with it to speak of (problems aggravating enough to make me want to destroy it yet again).
So my suggestion to anyone who owns this phone, or is thinking about owning one: Don't install any more than a couple small apps, add a 32GB uSD card for music and other stuff, and use the thing as a phone and a media player only. The camera is pretty much worthless for quality photos, so there's really no other use for it. But it makes a great txting, voice calling, and music playing phone!
Of course, if you end up paying more than $30 for it, you probably paid too much. But it sure is a pretty nice phone for 30 buck!
Yes. root it please
I have a Z833. The phone only lags apps that are over 100mb I'll have test this out agin
I have ordered one of these phones for $20 should be here by Monday. When it arrives I'll be able to confirm if its bootloader is unlocked or not. In the meantime here is the firehose and support files (rawprogram0.xml and patch0.xml) as well as the MetroPCS B16 firmware to be flashed with QFIL or MiFlash. This will allow people to recover their device and hopefully if the bootloader isn't locked flash custom images.

YA 4.4.2 Bootloader Discussion

Hey there remaining Verizon S3 users!
Coming from my favorite device the T959V this has been quite a trip. This device's bootloader is seemingly impossible to unlock on the 4.4.2 NE1 firmware.
I've got a slightly modified Superlite rom rolling with SafeStrap already strapped. And it is great to say the least. Added some initd and utilities. Evie launcher is pretty nice btw- recommend a try :good:
However. I still really want this thing to be unlocked. The T959V has multiple working Fro, GB, ICS, JB, KK, L, M, AND Nougat ROMS. Totally different devices yes but-- even the newer S4-S6 have cracked loaders now.
There has to be a special way to change this things firmware.
Right now I have 2 ideas to throw out to the wind-
1- Would be that there could be a way to trick the device into thinking it is receiving a new update. Maybe somehow with CSC or something. Also I saw a file named authorized.xml and was reading through to find traces of knox. Would unauthorizing knox strings somehow render it useless?
2- I was reading a suggested post about AVB boots and how they can be resigned on devices such as the Google Pixel and allows the newer patches to still install. Including what was described as a forced re-sign method.
--- Could we somehow resign the bootloader on our device so as to gain control of it? Has anybody tried anything like this since around 2015?
I'll gladly talk about all of this more whenever I feel like popping on- and atm I have no web besides this service. :silly: so no DOS updates and no shiny linux for now.
Gladly tell me that it is "impossible" but I'm not asking that. I'm trying to add some ideas to possibly do the impossible.
Edit: This seems to be an interesting lead on emmc cracking this device. It's probably why people in other threads were in search of a "dev" edition.

I've been around this and many many other forums for years now. If there was an unlock method it would of been found years ago. Devs have long moved on from the old S3. I still have my S3 lying around, bootloader unlocked but I really haven't messed around with it for quite a long time now
And yes the dev edition would of been nice had someone actually had one, it would of of course made it easier to crack the bootloader option maybe. I don't know much about the ins and outs of the device but I know many are permanently locked and will probably never be unlocked.
As far as certain other Samsung devices being unlocked those are far and few between. VZW got smart and started just locking them from the start. This is a huge reason why I left Verizon. The S3 was my last device on big red. I since have had a Nexus 5 and 6 and now a oneplus 3t. I really don't like locked devices and the ability to unlock them and customize them just intrigues me to no end. Good luck however in finding something that may work, but I highly doubt it will ever be cracked

Ya I expected your negatude Shapes. Already seen that you have been searching but it isn't just some application you run. It's an unknown exploit that I'm sure exists. There are exploits right now that can be considered viral potentially exploiting my device as we speak. Maybe not granted my semi-precautious take on things.
Quadrooter and dirty cow could be used to exploit the S3 and gain access to a quoted "all" physical memory. So I find it hard to believe that things can't work in our favor.
Being open minded here. After all, this is technically hacking your own device. Which--
Got me thinking the other day, becausr I was setting up my laptop proper- could we run a nix distro and poke through the bootloader's parameters via exploitation tools? Referencing Kali or it's elder BTrack. But I think it is possible and I just haven't gotten around this loop mounting issue.
To be clear, running a distro ON the device. My flat is already running square.

Also a purposely separate post- I'm building a ROM for this locked firmware and the goal is to have some specific updated apps and yet trim it nicely so as to save space and RAM it's mostly stock style-wise but it'd be cool to re-theme it. I haven't gotten things deodexed yet- being I haven't gotten my apktools working proper yet.
Is there anybody left to be interested in this? I haven't posted anything I've made before- usually just keep them lying around for emergency flashes.

I don't think shapes was trying to act negative at all, just stating the obvious. Nobody is going to try to unlock the Verizon S3, it's pretty much a dead end.
The unlock method used on the S5 will most likely work on this phone, but we need a developer CID to rewrite to the emmc as the series chip used on the S3 likely has the same vulnerability. This is what happened on the S5.
If you read some of the other posts (sounds like you have), we looked for an S3 developer edition but had no luck in tracking one down. For one, it's an incredibly old device. Secondly, you'd have to be semi retarded to purchase one as the original unlock method was around before the developer edition was released.
So yes, if you can find a developer S3 this will likely be an unlock method. It tricks the S3 into thinking it's a developer phone and unlocks the bootloader if the method to write it works the same as in the S5.
As for your questions,
1. I think you're underestimating the amount of security that goes into the bootloader itself. If you want to learn a lot about Android security in general, in the Android security discussion section located under general forums, there's tons of info regarding how complex this all is. But basically, in order to send an update patch, it needs to be signed (you can't just fake the signature) and it must agree with the current bootloader. The way the bootloader is written, it simply won't allow a reversion back to earlier versions or it'll abort the boot.
An easier way to think of this is understanding that the changes made are preinstalled before the actual boot. There's no way for us to change this through normal methods as the emmc has to be written to directly. There is no way to do this from download or recovery mode. Wouldn't matter if you flashed it or used and update package, they are essentially the same thing.
So the only way to actually change the bootloader is to write to the emmc directly through use of the JTAG port. This changes the code of the entire bootloader before the boot and the phone will boot up with any version of the S3 bootloader you write.
2. I think I kind of answered that?
Hope it's clear.

Truthfully after being around the forums for as long as I have I'm really surprised there is any interest in unlocking this device at this point in time. There are just so many other options and unlocked vzw s3s are not that hard to come by.
And I wasn't being negative it's about being realistic. Thanks for sticking up for me brother

Are there any updates to this by any chance, I am interested :C
any hope?
