<<<Which firmwares can be downgraded. Which cant>>>Dont hardbrick your device - Sprint LG G4

<<<Which firmwares can be downgraded. Which cant>>>Dont hardbrick your device
I'm posting this because there seems to be new g4 users popping up.....
LG Uses antirollback or qfusing to stop you from downgrading certain firmwares
Ends in secure boot errors or worse!!!!!
!!!!!!!!!!!You cannot currently downgrade ZVD to ZVC or lower. Or brick will result!!!!!!!!!!
And as of rite now there is no Zvd .tot file available that I know of,To fix bad things when they happen and they will.......
Update there is now a ZVD .tot and it has been confirmed we can go from ZVF to ZVD safley no lower.
I dont know the exact method but it seems that you can go from ZVC to ZVB no lower.....
If you are on ZVA or lower u can downgrade to ZV6 and that's it no lower. Or if u go any higher ZVB,C or D. You can never come back to ZVA or lower......
!!!!!!!!!!!!!!!!!!There is no root method for any other firmware than ZV6. !!!!!!!!!!!!!!!!!!!!!!!!!!
So please for the love of it all. Please be careful in upgrading and downgrading. be sure that is what you want before taking upgrades.. you may never get back where you want to be.
Even with a pending nougat update. dont jump he wagon unless root is confirmed...
a zvd root method could come out tomorrow or never you never know.
IF U HARD BRICK OCTOPLUS BOX WITH JTAG IS ONLY FIX NO OTHERS
I hope this helps with some of the confusion. ...
So no up and downgradable firm wares go as follows ZV6 7 8 9 and A can be downgraded to ZV6 so if B or higher THIS IS NOT FOR YOU..... ZVB and ZVC are interchangeble only betweeen the 2
A ZVD E and F are inter changable between the 3 SO FOLLOW THESE GUIDES HARD BRICKS CAN AND WILL OCCUR!!!!!!!!

Maybe that's a bit too limiting of a description.
From what I understand, it's perfectly fine to downgrade from ZVC to ZVB, correct?
So you can downgrade if you are on ZVC, just don't try to go all the way down to ZV6. Just downgrade from ZVC to ZVB, so you can install the mellowmallow ROM.

ok i was starting safe as i am zv6 i dont know exactly which ones
but again there are some newbies with the g4 and am trying to avoid bricks
i know to flash the mellow mallow zvb over zvc u have to open send port at 9 % which is extremly dangerous.
not sure if a man just flash zvb .tot over zvc in flashtool.

hey check that out and see if thats better im not a guide poster kinda guy more of a doer does that suit a little better and clarify.
and man if u know somethin i dont feel free and please add.

"I dont know the exact method but it seems that you can go from ZVC to ZVB no lower"
Yes ZVC can be downgraded to ZVB (no lower). Mostly for the purpose of Mellow Mallow global unlock rom.
You simply flash ZVB ls991 stock downloadable firmware over ZVC with LGUP
Additional notes
ZVB cannot be downgraded
ZVC can be downgraded to ZVB (no lower) (Mellow Mallow global rom is available on ZVB)
ZVD cannot currently be downgraded............there is no known method.

So, if I'm on ZVE, I'm out of luck?
Didn't really think to look to see if the G4 was rootable. Digitizer is cracked on my G2 so I grabbed a second hand G4 for 100 bucks as a quick fix. Whoops. May have to resell.

Yeah, I'm not that worried about bootloops as I don't use my phone for hours at a time. I really like the camera, too bad it doesn't look like I can root. Some things are really annoying though, like the huge nav bar. Xposed/tweaksbox helped make things pretty nice on my g2.
I was planning on just using this phone for a few months until next gen and see if any interesting phones come out.

Some of the best pics ive ever taken has been with the g4. I got a tripod setup i made. I do a lot of light scribing lite writing and star shots. You wont be disapointed there.
Ive been working on some crap for the g4. A zv6 rooted rom. Not goin to well but im hoping to release it in the next month or so ive been keeping up with all kinds of new exploits to test to see if we can get root but not going well either

Nice, I do have a dslr for that kind of stuff, but it is nice to have manual control on a phone camera. Can get some nice shots.
It looks like mine in the newer revision at least, Nov 15, 1.1 board so maybe it won't bootloop and someone will figure out how to root this thing, I may grab another damaged one for cheap and have a go at it. I may add some thermal paste as well just to feel a bit better about it. It does get to about 80-90c during benchmarking according to cpu-z on the large cores (sensor 13/14 I believe), idle is decent though, around 35-40c or so across the board which seems to be lower than many I've seen online.

Ha, nice. How about if you run stress test in antutu and check temps in CPU-Z? Mine gets toasty if I do that. I would be a little more comfortable at like 65-75c like my G2. 80c+ makes me a little nervous. I remember a lot of PC GPU's had that issue in both laptops and desktops and everyone was trying to bake them. The key is to keep it cool, and the G4 seems to be hot because LG skimped out on some aluminum.

had to bump this back up

Has anyone tried to downgrade ZVF to ZVD?
I know ZVD has antirollback, but I don't know if E or F does too.
I have the ZVD tot, but don't want to risk it...

[Tutorial][Bell Atrix]What need to be done before Warranty Service?

[Tutorial][Bell Atrix]What need to be done before Warranty Service?
It applies all the Bell Atrix, doesn’t matter you have Orange FR 2.1.1 or UK 2.2.3 on the phone or whatever
Simple Version:
Make sure you have CWM Recovery on it(http://forum.xda-developers.com/showthread.php?t=1019143)
Download the stock system.img (http://www.multiupload.com/T6L5RS2WH1), if you have the backup by nandroid, you can skip this step
Enter CWM Recovery to restore system.img only, then do Wipe out Data&Cache, or Force Close will be with you!
Install GingerBreak to root your phone, you can download from here: http://forum.xda-developers.com/showthread.php?t=1044765
Install CMW Recovery again, but this time, choose CHARGE MODE in order to uninstall the custom recovery
Use GingerBreak to un-root the phone
Do a factory again, then you are ready to throw this phone to any Bell Retail Store for repair
Just remind that Bell will take 4~6weeks to get your phone fixed, if you need a loaner phone, it’s $25+tax, ask before borrow since some store doesn’t even have smartphone to lend…
Full Detail Version coming soon...
Thanks, good tut to have.
Stock Bell Atrix on Rogers with updated radio, Rooted, deodexed, Honeycomb theme, and frozen!
With glad root and webtop mod on stock firmware would it be ok to just return the stock web top files and unrooted for warranty?

Yes, but in your tutorial you're just removing root access and custom recovery. You're not changing the firmware from the phone back to 0.3.7 (Bell firmware) because there isn't a Bell SBF to flash (you're right about that). If one was already running 2.1.1 or 2.2.3 with root access, they could simply reflash their respective SBF's and it would produce the same results as your tutorial. Maybe I'm missing something from your guide, but as far as I understand, once you've flashed a different SBF, there is no way of getting back to official Bell. Your guide seems to be a roundabout way to get back to stock 2.1.1 or 2.2.3 for warranty purposes, while a simple reflash would produce the same results.

absolutely true.
best chances for full repair is flash stock SBF 2.2.3 and then if you really wanna get technical, simply edit your prop file for cosmetic purposes.
NFHimself has this crazy way of flashing close to stock images but thats pretty much retarded as there's no point as it really doesnt mean any closer to stock than this crap and is fickle/easy to detect as it is if Motorola was looking for it.

You are right, however stock system.img(from original bell firmware, not 2.1.1 or 2.2.3) already has the right prop file and bell bloatware, comparing 2.1.1 or 2.2.3, im too lazy to look for bloatware and changing by root. this seems the easiest way for me.
other than the radio version, i dont think motorola could find out this is flashed Atrix but anyway, I am still waiting for my atrix back

I work for bell. and all I have to say about this thread is that it should be closed and deleted. I actually thought these kind of guides were frowned upon...
If the phone was working 100% before you starting screwing with it, we shouldn't have to honor your warranty. Thats why ROOTING VOIDS Warranty.
If you screw up your windows load, Best buy doesn't say, heres a new pc. They say, here's a bill for the techie. We work on commission in these stores, and i hate wasting my time with some moron who shouldnt have screwed with what he couldn't fix. /rant
Its annoying to deal with people who brick their phones, and then give bs excuses as to why its not working. I usually do my best to help people, but its better to tell us the truth and have us help, then lie through your teeth that its a problem with the device.
It costs me extra hours of work to deal with DOA phones, and it costs everyone including motorola tons of $$$ for stuff that is screwed up by the consumer.
Why can't the people who don't know what theyre doing, leave the dangerous stuff to the guys who know how to fix their own problems?
Edit: the exception to this is true hardware issues. But those don't seem to come up all too often with this phone, just battery life issues.
But thats the thing if you brick your device, this guide won't help as the phone is a brick.
As for hardware issues, this is the exact reason for this thread IMHO, something useful to me as my fingerprint reader is slightliy off physically which results in the device thinking that fast swipes are taking place when they are not. now I can use this when I am ready to take my device in without being harrassed about software.
With my N1 even with the bootloader unlocked they still took in the device if it was proven to be a hardware defect (again had a problem with my power button - just my luck i guess) Doubt bell would do the same.

QFT, but......we are referring to hardware isssues here, not software.......and rooting has nothing to do with that.
Sent from my Blue Myst GladiAtrix on Bell using the XDA Premium App.
I agree, its totally cool for hardware issues, but i'm thinking about the guys who have the lower half of the touch screen not working because they screwed the software up. 9/10 issues with any smartphone is software related.

binary110 Your completly in the dark if you think this phone or any other smartphone wont have defects and hardware malfunctions.
My Atrix has wicked bad screen response when plugged into any power source with stock charger or other... im not returning mine as this is a minor issue. Although my roomates cant hold gps, drops calls constantly, misses calls and msgs for lack of signal and has constant reboots since stock with only root to obtain webtop mod.
So according to your logic he dosent deserve to have his 500+ $ phone replaced cuz it will cost motorola money and your lazy ass some commision ??

I never said the phone was not capable of being defective. I said that when someone brings it in for an issue that they caused themselves. The phones are more often screwed up by a customer, than they are actually defective.
90% of the charger issues are from using a charger different than the motorola one that came with the phone. Especially the ones with the screen response. I noted it on my atrix as well. I also have replaced a customers phone for this.
This IS a valid reason to replace the phone.
But this is also easily noticeable BEFORE you go through the process of rooting/modding the phone. and as such, you should take it up with the place your purchased it before modding it.
Its like buying a car, ripping the engine apart right away. only to find that it runs like crap after you've ripped it apart... You probably should have done a test drive before purchasing. Do you understand what i mean?
Furthermore, your friend has a legitimate issue, I'm talking about people who brick their phones and play stupid. As well, I can tell you're a part of the generation who feels they're entitled to everything under the sun from the carrier you deal with. Yet, no cable company fixes your damn television. And especially not if you screw it up yourself.
Its not apples to apples, in the sense that the cable company doesn't subsidize your tv. but even if you got a tv as a promotion through them, they'd send you to the manufacturer. Which is what i'd prefer to do with people who do stupid stuff and want it fixed.
Don't act like my time isnt worth money just because youre a needy consumer. What i'm saying is just man up, tell us you screwed it up, and we will do everything we can help.
For you to be trolling the way that you are, its obvious that this ISNT THE FORUM FOR YOU.
Thank you.
By the way, Watch your language on the forums.

Uhm, what? How did I get dragged into this PMS fest?
Ridiculous.
Be nice guys... We are all Canadian, we love peace, don't we?!
In my case, my touchscreen's digitalize is 100% broken, it's either hypersensitive or non-sensitive at all... It happened on Bell Stock rom but I was trying to flash sfb to see if it could be fixed...
Unfortunately, i got my repair back today and still the same issue, i asked the bell staff to try the touchscreen and she said the phone is not boot up properly...
Oh well, after 90s, I ask her to try again, she clicked "BACK" 10 times in order to get back, and 5 times to run Bell Self-serve
well, I really unsatisfied with the result and I had to left the phone there and waiting for another 2 weeks, AGAIN!!!
I have 3yr contract with Bell so it has to waste time and money to get my phone fixed cuz its carelessness and impatience are wasting my money and time... The $30 loaner phone sucks and cannot even been changed...
well, looks like a little away from the topic but I've just out of the store...
even according to the repair menu, the bell stock sbf has been applied on and change of the part which i know its not the digitalize, the phone is still unusable...
AT&T users are lucky since they have their own stock sbf to flash when they wanna a repair but poor Bell users they have to use those tutorials like mine to do repair, OR UNLOCK THE BOOTLOADER AND I WONT ASK FOR WARRANTY
btw, maybe that's the reason why Apple is cool, they can get your iPhone replaced in maximum 60min not 60days even there is just a dust in screen

I understand where binary was coming from but again this thread isn't for that reason. At the same time I bet we can all say we wish carriers like bell and rogers were completely full of staff like you that come with the line we will do whatever we can to help. most times reps come off as just going through the motions or looking for whatever reason to close the case.

Is anybody else considering switching to a nexus?

I have missed my nexus 5 ever since i gave it up for the s5 and now the g4.
Anybody else gonna switch when the new nexus comes out?

Just my 2 cents worth, but I would actually wait until the Sprint update ZV6 (releasing now), see if it fixes the lag/touch and other issues we are experiencing. I am confident we will eventually have an unlocked bootloader, but as long as we don't lose our root method -it really isn't required since i'd rather run a stock modified anyway (for myself at least).
Rumors show it to be less of a phone than the G4. If it was equal I would have considered it.
Smaller Screen, no rear buttons, no laser focus, no spectrum analyzer, no SD card, lower res camera, less RAM, Non removable battery.
It does add two tone flash like HTC phones (better white balance). But I love what G4 does in that space, Auto White Balance is amazing on G4.
G4 doesn't feel like a phablet, but has the screen of one.

I don't feel lag/touch. However I did HAVE to remove my screen protector, that was definitely messing it up (never happened on any phone prior). The phone feels zipper than my HTC M9.
I'm not confident at all we'll get an unlocked bootloader. I think carriers won't allow it. Just like Verizon blocks unlockable HTC phones. Things are moving towards more lockdown, not away.
Might see it on T-Mobile or something.
Also I looked at the unlock procedure for the European models. First step is enter Bootloader. I can't, it zips right past it. Maybe I'm doing something dumb.
Also I'm not saying an update would allow entering the bootloader.
Someone also posted a chat with LG on this topic that there is some technical reason it's not possible to do on the non European models. That's might be B.S.

Yeah im not very confident we will see a bootloader unlock, if they would have let us unlock it from the get go we would have fantastic aosp roms already, i willing to take the compromise of a nexus in lieu of stock android and bootloader unlock right out of the box.

Even if all the US carriers allowed the bootloader to be unlocked this instance without voiding your warranty it still would not matter. There doesn't seem to be that much interest with this phone in the modding/dev community. I doubt that will change because everyone is always waiting/looking out for the next big thing is it is doubt we will see a surge this late after it is released.
I am just keeping this phone to get used to the fact that rooting and modding phone is going to get increasingly difficult as time goes on. The good days are over
Really wish the One Plus One would give non-gsm some love.
We may never get an official unlock, i bet there will be a workaround of some sort just like the G, G2, G3. If not, this would be the first G series that doesn't get a recovery workaround. I've been working on the LG series from the start, not giving up now.
Just waiting on the new ZV6 update. We should also have M being their flagship.
My last phone was a Nexus 5 and I prefer the G4. The battery life is just way better and my extra batteries makes it sweeter. I do wish G4 has vanilla android, but the G4 is good enough.

Even if all the US carriers allowed the bootloader to be unlocked this instance without voiding your warranty it still would not matter. There doesn't seem to be that much interest with this phone in the modding/dev community. I doubt that will change because everyone is always waiting/looking out for the next big thing is it is doubt we will see a surge this late after it is released.
I am just keeping this phone to get used to the fact that rooting and modding phone is going to get increasingly difficult as time goes on. The good days are over
Really wish the One Plus One would give non-gsm some love.

I agree, most developers have chosen their phone for the season.
I had an HTC M9, just got it replaced and gave it to my wife. I really looked carefully (Spent way to much time). But this is one awesome phone. Assuming I don't run into reliability issues some folks have.
I see quite a few regrets in the XDA Samsung Forums which I monitored closely.
One plus about how we are rooted is, it won't void warranty (you can get it back to pure stock). Samsung you are screwed if you have an issue.
HTC you can relock and most techs won't care if it's relocked. If the tech saw S-Off on an HTC and knew what it was (some do) you'd be screwed.
I just used Ut-Oh to replace my M9 that had S-Off, so that's another plus.
Will be curious what HTC's next phone looks like. It has quite a distance to catch up. I'd much rather have wireless charging than a solid metal body.
I came from a S6 Edge 64gb which I got bored with and gave to my wife and got this phone. I think this phone is awesome. The S6 Edge doesn't have anything on this!
SD card support with removable battery were huge factors! The only downside is the locked bootloader with no TWRP support

Inducing Bootloop

Hey I'd like to know the best way to make my G4 bootloop. I've already had a past G4 replaced due to the bootloop issue with Sprint and just recently people are getting their G4's replaced with newer phones if they bootloop. Now this replacement phone already had a screen issue giving me horizontal grid-like lines underneath the glass and I've about had it with LG's crap. I want to induce a bootloop because a Sprint representative said that would be the only way to do so.
Nuke the bootloader. Theres a post around here somewhere about zeroing out the aboot or something
Honestly the funniest thread I've seen on this forum in a long time. :laugh::laugh::laugh:

Are u rooted if you are just delete a load of system files delete it all
If ure on zvb try to flash zv6 firmware i heard it bricks
Best way to get a free g5 or HTC 10. Break the device and have the g4 replaced by insurance for as long as they are swapping people out to those models.

erasing laf did not seem to have any effect and flashing zv6 on top of zvb is not possible lgup will refuse. even if you somehow force zv6 ROM via dd, you should always beable to go in to download mode and reflash with LGUP or LG Flash tool. or am i missing something? I do not think there is a software method to hardbrick this phone on purpose?
I dd systemZV6.img and phone will get stuck in LG logo screen. But if I put it in download mode and LGUP ZVB image it's back up and running
Who is it doing the replacing?
If it's LG sending out G5s or V10s when you send in a bootloop G4, then I'll let you know if it's true or not since my LG G4 started to bootloop as per the known defect and I sent it in for warranty replacement. Though it's been two weeks as of tomorrow and they still haven't updated the status of my claim since receiving my phone.
If it's supposedly Sprint replacing the phone with a newer phone, I find that hard to believe since they told me to go through LG if I didn't want to pay the insurance deductible because the bootloop from hardware defect is being handled by LG directly.
Either way, as soon as I receive a replacement device, I'll post an update to this reply to let you know what happened.

I can confirm that LG will not replace the phone with anything newer. I just spoke to someone at the warranty and repair center for LG and they're replacing the mainboard, flashing a factory image, running it through a battery of tests, and shipping it back out to arrive in 5-7 days.
I wouldn't get your hopes up about Sprint replacing it with something new this late in the bootloop game as their early upgrade and exchange offers have all ended for the LG G4. Unless it was the retention department of customer care, they're probably not giving out any replacements of a different model.

Based on what seems like tons of reports from XDA and the LGG4 sub-reddit, it is Sprint stores that are exchanging boot-looped G4s for newer devices. I'm also interested in inducing a bootloop for this reason, and am running a looping CPU stress test app to get the phone nice and toasty for a sustained period of time (days). I will report back if I have any luck!

I'd be careful with that. From what I understand, Sprint isn't doing that anymore and they tell you to go through LG. I just got mine back from LG literally 8 minutes ago after waiting almost a month.
Though they did replace more than the main board, which was nice. They replaced the front bezel, screen and digitizer as well. Except for the battery and battery backing (you don't send those with it) they basically gave me a whole new, thoroughly quality controlled, G4. I think the display was upgraded in some way though, because the sticker covering the screen was different than when I bought my G4 originally. It says "Quantum IPS Display", where it didn't on the first one. I haven't seen my g4 in over a month so I can't say whether it looks more vibrant like they say, though.

What firmware did they ship it with? I'm still rooted on ZV6 and don't want anything newer if I send it in.
I can verify that Sprint is not exchanging these phones out with newer or different models/brands. My phone just slowed to a crawl and then stopped functioning and when rebooted stayed at the LG Life is Good boot screen. This happened only 2 days ago, 3 weeks after my sister's exact same phone/model did the same thing. I had to lay down the "I've been a loyal customer for x years" line on them just to push my upgrade up so I could buy a new phone (HTC 10 here I come). I will however send this phone in to be repaired, but I doubt I will buy another LG phone again after this issue.
new idea for bootloop

My phone has dead because bootloop but i leave it in to fridge (supercooled) my phone frezee but i open it and it not bootloop. wow amazing revival.
straightway i think need close chip A57 (dead chip) by app Knel toolkit (pls search google) . now time it working normal.
but app knel toolkit problem stop working if you use phone alo app and hang on app.
i have new idea.
1st: why not use editor new build prop not use chip A57 at boot startup.
2: write good app for close chip A57 (Knel toolkit stop working if you hang on app.. and A57 working again to errno your phone)
my video revival my phone facebook ..../ntientuan/videos/951862408255600/
Will an induced bootloop work for the warranty replacement, or will they only fix it if it has the actual defect?

LS991ZVD Has upped the count

With this update no longer able to use the ZVBTOT as it is lower then the current version. LGUP gives the error message and phone reboots to system. Another door closed on the G4.
Not paying attention I thought I was only updating to ZVC. When I checked the screen to if any progress had occurred; I saw same message the update was downloaded etc.... In my haste I thought I had not started the ZVC update, so answered yes and slept in the recliner too tired to get to the bed.
Got a rude awakening today while trying to go back again to MellowMallow_LS991ZVB_v1.04. After attempt bombed out with error message, I checked to see what was happening - I have ZVD instead of ZVC which did work with the ZVBTOT.
ZVD closes another door. There may be another way around it, but I haven't found it.
A plus for the ZVD is my phone only used about 5% power during the time I was sleeping. usually I wake up to a phone with 30-45% left.
hope this helps someone avoid going down this path.

I was forced down this path by bootloop and LG repair practice of updating all repaired phones to latest firmware, posted about it yesterday.
I have noticed better battery performance too, that is the first thing I noticed. BUT I would sacrifice that for self-unlockability by global mellow-mallow rom.
A lot of people are anticipating the possibility of further news about a possible all-variant unlock/relock BL breakthrough, and if thats the case, hopefully there are enough devs left with G4 sprint interest.

As i am still on zv6. Dont know how this works on zvc or zvd.
But worth a shot
I think i tried that right after she upgraded it. Forgot to tell her not too when we got the replacement. First g4 bootlooped after 8 months.
I got the screen from amazon only screen with 12 positive reviews....teseko brand. Hope is good if its ok i might get one for my g3.
Running my g5 now, had it for about 5 month but only really used it as daily the past 2 month and my power button barely works. Went from acting up to almost not working in a few days. Getting fed up with lg.... The g3 was/is great....after about 2 almost 3 years my g3 just now has an issue where the screen doesnt respond that great...as in i try to scroll up but it clicks the page......
The g4 (my wife's) bootlooped after 8 months. My g5 has the power button issue after 2 months..... I wonder if i replace the screen on her g4 how long it will last till it bootloops..... Or if my g5 will too.
I think at some point i will have to switch over to galaxy or something else. As much as i like both g4 and g5 the quality is just way too too bad.
Anyways im venting......but....
Thank you for all the tips..... Hopefully a way is found eventually.[emoji4]

Since i am replacing her screen i am going to do that too (thermal paste)... Too bad i cant root it it for tether but oh well.
I think i will fix the g5 myself and use it or fix the g3 and keep the g5 as backup. Sprint did away with the bestbuy 2 year upgrade and their online 2 year is not the best of deals so.....who knows. Cant leave sprint though....service has always been great, my old truly unlimited plan is crazy compared to whatever they have now anywhere.. Just under 300$ for 6 lines unlimited data.....only got one warning letter when i forgot my home cell phone playing a romanian radio station on high bitrate for like the whole month.....used about 300gb and they sent a letter for that line....i checked and i was like what a moron i am...:laugh:

I came here with the same question as the OP. What is the deal with the LG G4 and rooting? I've had this phone for two years now and not once has there been a root option for it. I've never had this issue with any devices I have owned previously. And I'd hate to have to buy a new device just so I can finally have control over what I own. Especially since I just paid off this one. Sorry for my frustration nothing personal to you but I'd really like to know why we don't and never have had a root available.

Cant root mm without a unlocked bootloader because to root mm u have to modify the kernal which messes with the secure boot chain. And gives secure boot errors.
Anti roll back prevents u from downgrading to a rootable version. Making hard bricks. Its sad but true. U need a diffrent device to root.
I actually put my g4 up again. Its having some issue
Im sure a really good dev like chainfire or someone of that knowlege could root it but theyve all moved on to more worthy devices
The g4 died well becore its time.
Only reason i got root is mine never bootlooped. And at the rates its goin never will.
Ive atempted so many diffrent methods and ideas to root mm on emulated mm roms on pc. Nothing.
Ive atempted some many methods of downgrading and nothing but bricks. Never boots. Always boot errors. I wish i could update. Being stuck on lolipop with no hope for mm or nougat if i want root.
But again. It is most def better to get a root friendly phone
Had I know this was going to be the outcome I would have gone with something else maybe even waited longer to upgrade. I bought this one on the promise it was rootable with a matter of time. I won't do that again. I simply can't afford to spend $500+ every two years to make sure I have a rootable phone when it should have that control stock. Just hidden toggle for it so morons don't do stupid stuff.

i know its dumb i learned a valuble lesson in the g4 one dont buy the newest unless its confirmed rootable.
and 2 do my research and make sure what i want to purchase is rootable.
i know how u guys feel now my g4 is about dead i just like skulking around the threads still
i got mad and threw it. busted and bent almost in half.
well i put a old cracked lcd on it i dont have wifi any more thn 5 foot from my router.
my earpiece is dead. ir ports gone. rear camera also but it still makes and recieves calls and data
i got a zte max x 2 i think it is but im in the same boat crippled fastboot and bootloader
on mm with absolutly no root in sight no stock firmwares to fix it even if i brick it in testingroot methods

no this is one of those things id put my g4 on a shelf and get a rootable device i know easier said than done but will save u a lot of headache if u quit on it now
this thing prob wont be rooted anytime soon
ive tried everything i know and ofcoarse all in sdk simulation and all leads to hard bricks
it sucks i have mines still on zv6 rooted but the mother board is damaged and i have very little wifi signal and no mi crophone
ive tried to update a zv6 rom into thinking its zvb and higher but no luck anywhere
im def no developper but i really dont think the real devs even trying to do anything with this device which i cant blame them moved on to better devices
It sucks. I have been using my g4 for two years and am pretty happy and dont have plans to upgrade, since newer phones do not offer much as compared to g4. I was hoping that someone will eventually find a way to root it again, whats wrong with people, no one has time to make this happen?
