wondering if anyone else facing kind of issue,

regards
[LG G Flex 2] ralphn8r:
I just rooted ZV9, found the rooted image here: http://xdaforums.com/showpost.php?p=64087953&postcount=378

EDIT: Just tried typing supers into play store, didn't get a crash. So ZV9 might fix your issue.
[LG G Flex 2] mauchito:
Is ZV9 better than ZV6? I just saw that it contained some security fixes, but is it any faster or something like that? Any noteworthy changes?
[LG G Flex 2] ralphn8r:
ZV6 was already well-optimized, so I don't see too much in terms of speed, but I have noticed that I'm getting much longer battery life, and the phone doesn't get as hot as it used to. Not sure if this is what everyone else is experiencing. But either way, I updated for the stagefright fix, which is super important to me. There's also a GSM improvement, but I haven't had a chance to see if anythings really changed with my network.

Anyway, here's my battery life now:

Hi Alex_XV6700.

Thnks for zv9rooted. And thks for all tour advises.

I want to ask before i do because i did brick 1time. Now i m in zv9 unroot, can i flash unroot zv7 by dd commend or not?

Thks a lot
[LG G Flex 2] abhishek.banerjee:
No you should not

This has been mentioned

Why do you want to go back to zv7 from zv9?
[LG G Flex 2] larrylong:
I want to try back to zv7 and ota update to zv9
[LG G Flex 2] Alex_XV6700:
If you're on ZV7 flash the zv7 stock and then ota update to zv9.

But if you're already on zv9 then all you have to do is flash rooted zv9.
[LG G Flex 2] larrylong:
Thank for yr advise.
[LG G Flex 2] larrylong:
I forgot and did factory reset,now stuck on lg logo,only enter download mode,anyway can use dd command from ext sdcard or any solution?i m in rooted zv9,ls996.TIA
[LG G Flex 2] Alex_XV6700:
if you formatted internal sd there is no way to flash from external sdcard...
[LG G Flex 2] larrylong:
You mean factory reset? It is so sad and have to wait for solution from dev.thks
[LG G Flex 2] chetveriks:
use of sdcard in Firmware update MODE

hi

as phone freezes at SETTING UP YOUR PHONE while android starting up...i cant upload any ZV to the phone

i tried Factory reset - so all memory erased. only can use external cards

was with rootedZV9 - phone was frezzing time to time. Downgraded to rootedZV8 - and it was saying Google services stopped, and phone was freezing.

after Factory reset - it freezes on SETING your phone.
[LG G Flex 2] Alex_XV6700:
Didnt you read the thread? Its pointless to downgrade using stock or rooted imgs. Its best to use backup or stock sys img to restore the phone. Test it and then root with the corresponding rootedsystem image
[LG G Flex 2] chetveriks:
.It is now zv8 rooted. How I flash stock img having no acces to internal memory?
[LG G Flex 2] Alex_XV6700:
You just cant...
[LG G Flex 2] chetveriks:
So. It is a brick?
[LG G Flex 2] Alex_XV6700:
Yes sir... If you can send it back for warranty.
[LG G Flex 2] chetveriks:
No waranty unfortunately. But I can not get why G Pad can be flashed using flastools and LS996 not?
[LG G Flex 2] chetveriks:
And. In case with HardBricks phones not even turns on. This even loads Android. And enters Download Mode.
[LG G Flex 2] Alex_XV6700:
Sprint hasnt released any TOT or KDZ for this model. And ZV6 - ZV9 have anti rollback so if you try to flash ZV5, you will hard brick your phone. I dont get it either why they dont release the firmware that way we can clean update or clean restore.
[LG G Flex 2] chetveriks:
Isn't kdz can be created by local guru's?
[LG G Flex 2] asamu694:
HI

What process did you use? Can you please share.
[LG G Flex 2] Alex_XV6700:
No. Or maybe?

Usually we get kdz or tot from leaks or someone in the community gets it from a friend or contact inside the carriers techs.
[LG G Flex 2] Alex_XV6700:
Download stock image from here and use the same process as rooting goes in development section. Always remember to keep a backup on internal sdcard if anything goes wrong!
[LG G Flex 2] chetveriks:
Let's write a comunity letter to Sprint asking them to release tot of each version argumenting that they used Android which supposed to be an openware like Linux on which it based. Bla bla bla
[LG G Flex 2] Alex_XV6700:
That would be great... But we know sprint is pretty stupid with those things...
[LG G Flex 2] CloseCoder:
I tried rooting ZV8 but now my phone boots with a blue LED slowly blinking while the screen is black. I was stupid to not make my system backup but i rooted it in the past and no problems until now. Is there a way to push the stock system image to the internal or to flash it from desktop to the phone? i can only enter download mode, my computer reads the COM port as 441. Please Help
[LG G Flex 2] Sunnyartwani:
I mistakenly deleted lgsetupwizard.apk and now my phone boots with security error and turns off, moreover i dont i was on which firmware but the only thing I know is it was 5.1.1, can someone please guide how to get back phone to life
[LG G Flex 2] Alex_XV6700:
Nope. The only way is sending it to warranty.
[LG G Flex 2] Alex_XV6700:
Which model do you have?

How did you root?

Do you have a backup on internal storage of system or rootedsystem image?
[LG G Flex 2] Sunnyartwani:
I have LS996 , I bought it from ebay & it came rooted ,unfortunately I don't know if it has a backup on internal storage .The only thing i know is that it was on android 5.1.1 & build number is lmy47s , I have access to download mode & recovery mode.

I deleted lgstartupwizard.apk via titanium backup mistakenly thinking it was causing hand free activation & restarted.
[LG G Flex 2] chetveriks:
Is there a chance to get to inernal memory at service desk? Maybe they have special software?
[LG G Flex 2] Sunnyartwani:
Another thing I am sure of is it was not ZV9 as it was showing system update downloaded , can someone please let me know how to try zv8 system image over my system ?
[LG G Flex 2] Alex_XV6700:
If you didnt have a rooted or stock system image on the root of your sdcard you cant do anything. Unless someone releases a modded tot with only system image included in it. But thats pretty difficult...
[LG G Flex 2] Sunnyartwani:
unfortunately I am in India & can't send it back for warranty in USA , with lg g2 I remember we had total commander on pc by which we can see root folders if we have a similar software for ls996 it would work as I just need to place lgsetupwizard.apk file in the apps folder.

lets hope something happens soon.
[LG G Flex 2] Alex_XV6700:
Can you still access the phone then? Cause total commander only worked with adb and rooted device accepting shell commands... I remember this from flex1
[LG G Flex 2] Sunnyartwani:
I can only access download mode and recovery mode, my phone is rooted and recovery mode also showing many options such as apply update from sd card
[LG G Flex 2] Alex_XV6700:
You mentioned G2. Back then we had custom recovery... With flex2 we dont plus like I said you need a working system to use total commander so my best guess is wait for a modded tot or for sprint to release an official one (might be never) -_- sprint sucks at this with flex devices...
[LG G Flex 2] Sunnyartwani:
this guy claims he has tot file for zv8 : http://www.lgbbs.com:41/thread-973-1-1.html

seems fake what you guys think ?
[LG G Flex 2] Sunnyartwani:
Hello I just downloaded LG mobile support tool & it says its ZV5 rom , see the attached screenshot , now can I flash zv5 tot file ? If yes can can you guide on dll file & board dl (upgrade or new ) ?

Will wait for your response before going any further.
[LG G Flex 2] zinababo:
Hi

or any other way to get back to stock in order to recieve OTA

Amazing

Kinda new here so dunno if this is ok but kudos sir, both on the root for zv9 and the stock images.

Also to tdorid44 and randrew87 for root. :)

Truly, Thank you.

Real kudos also applied. ;)
[LG G Flex 2] Alex_XV6700:
If you remember that you were on ZV5 then use tot and flashtool method.

"How Can Flash my phone with img file ￼ my phone was zv6 android 5.1.1 after flash with zv5 turned off...

Use this guide (http://xdaforums.com/showthread.php?t=3169212) to flash. Read the whole guide to understand the process then follow it to flash your stock zv6 img. Where it requires you to use a rooted image, just use your stock image instead.
[LG G Flex 2] Alex_XV6700:
Read carefully he flashed zv5 over zv6.

That means his phone is hard bricked...
[LG G Flex 2] Lesta786:
Ohh, crud, yeah I definitely miss understood that. :( So there's no way back from that yet I'm assuming?

[LG G Flex 2] Alex_XV6700:
Man you gotta read the forums its all in here... Guides after guides...

And it has been said too many times "DO NOT FLASH BACK TO STOCK OR YOU WILL HARD BRICK ON LS996" Unless you are on ZV5. if you arent then you know what will happen.

really wish I had read this sooner:

[LG G Flex 2] Alex_XV6700:
EMMC backup of your version.
[LG G Flex 2] rAndroid3:
Hi there, sorry for posting before reading/searching info about it, I was a G3 user so I thought things were similar. Well, I was trying to replace stock apps with G4 apps, they don't work. I made a back up before and redo changes without problems, except contacts.apk and contactsprovider.apk, they FC's, tried changing permission, new apk and nothing. So I can't use now the dialer. My question is:

I'm on zv7 rooted, flashing system.img will fix the problem? Have I to flash stock img or rooted img? Thanks!
[LG G Flex 2] Alex_XV6700:
Flash any you want zv7stock or zv7rootedsystem.img any will work cause you're restoring complete system :good:
[LG G Flex 2] rAndroid3:
Thanks, last questions. Will I loose all user apps? It doesn't matter that I had some system apps frozen on TB?
[LG G Flex 2] Alex_XV6700:
Like I said you are only touching system not data or any other partition. This is not flashing complete firmware. I dont know what will happen with the TB thing. I dont use that...
[LG G Flex 2] rAndroid3:
Ok, I'll try and let you know. Thanks.
[LG G Flex 2] Alex_XV6700:
Alright :good:

Lemme know how it goes.
[LG G Flex 2] rAndroid3:
Hi there, I made a back up and flashed, anyway that ain't fix the problem. I think it's related to a different thing than system, idk, I keep receiving contacts FC's and can't access to contacts. As far as I remember I didn't touch anything else from system folder. Any advice\help.? Thanks.
[LG G Flex 2] Alex_XV6700:
Use flash fire and clear wipe cache and dalvik. Something must be bothering there.

Make sure you only select dalvik and cache.

The backup was before or after making changes?
[LG G Flex 2] rAndroid3:
Sadly, after changes, :( I'll try flash fire, I'm a little afraid of flash fire, I haven't used it before. But I'll follow your instructions and update. Thanks.!
[LG G Flex 2] Alex_XV6700:
Wait...

Can you access the phones internal storage?

If you can send the stock zv7 sys image from my forum and flash that one dude.

Do not hard reset your device ok?
[LG G Flex 2] rAndroid3:
Yeah the phone works completely, I can receive calls but can't access to dial or contacts. I installed 3rd party dialer and contacts apps and can dial, but you know, nothing like stock. It's weird cuz I can't see call log, but from 3rd party app can dial without problems. I think if I flash stock system.img the problem will persist, because I flashed rooted system without luck. I'm thinking in something, I can go back to stock and update to zv8 and see if that fix the thing? Idk you are the expert here :b
[LG G Flex 2] Alex_XV6700:
If you have those apps cached on normal cache and dalvik thats why standard apps wont work even though you flash stock or rooted system. Like I said b4 this doesnt touch any other partition. I suggest u remove TB, wipe dalvik and cache from flashfire and flash stock system image afterwards to see what happens.
[LG G Flex 2] WhiteWidows:
I inadvertently purchased a international unlocked LS996 from a ebay seller not realizing it until I tried to activate it on Sprint today. So hoping dd'ing ZV6 stock image would remove whatever the seller did for some reason still will not activate on sprint. Profile/PRL both fail. I have updated to ZV7 as well with no luck. I get 3g data. no lte or calls. I had called sprint and they said they had issues provisioning phones today and had a backlog. Not sure if i believe them or if its something with the phone

What else needs to be done to get this back working on sprint?
[LG G Flex 2] rAndroid3:
hi, its going from bad to worst. i used flashfire to wipe cache/dalvik, now i had all system apps crash, especially *system UI has stopped* now i cant use the phone. i flashed back up and system without luck... please help. :(
[LG G Flex 2] Alex_XV6700:
are you sure you just wiped dalvik and cache and not system?

Another way would be wiping data partition.

I saw that a user got his phone working on the LP Mods forum by Bountyman.

Wiping data and flashing stock system image.

You did use the ZV7 stock system image right? not ZV6,ZV8 or 9?
[LG G Flex 2] rAndroid3:
Hi, look, long story: as I told you, I made a dalvik\cache wipe, after that all system apps FC's and didn't let me use the phone. So I flashed back up, rootedsystem img without luck. Here comes the surprise; after several minutes receiving those system errors, I ended up receiving only one crash: "process. acore has stopped ". So every 5 seconds got the crash. So searching around on web I found so e information that the problem is caused due " contacts and contact provider apk (the same apk that begun all this) so the solution is to wipe data from those apps. So I frozen them on TB and wipe data from apk. And Bingo! Everything is working perfectly!! Also now I can use stock dialer and contacts! I think the problem was related to a bad data on cache\dalvik and wiping on flashfire and wiping apk solved the problem. The only thing I want to tell you is THANK YOU VERY MUCH! without your help I was lost! And something that I learned: wait until a .tot or custom recovery to be released or some secure method like G3 has. Now I'll be an average smartphone user like my girlfriend :p hahaha.
[LG G Flex 2] Alex_XV6700:
Hahaha. Thats great to know man!

Good that you did your research too...

Now if you´re gonna do some mods keep a backup on your internal sd always.

I debloated from gapps and other unnecesary apps by deleting them with root browser but I always keep my rootedsystem.img where it has to be just in case anything goes south.

Thanks for posting your solution :good:

Unroot and back to stock from LS996ZV4

Hi my Flex2 is LS996ZV4, it never got any OTA update since i rooted it very early.

i´ve been using it with Exposed Framework and some modules all this time to cope with its overheating issues.

a few weeks later i talked to a friend of mine who bought one with LS996ZV9, and it runs flawlessly!

So my question is:

Since i haven't had any luck finding the LS996ZV4 Stock Image, is there any other way i can unroot my cell and apply the updates? :p

thanks!
[LG G Flex 2] Sw33t_Lov3r:
Hello guys!

Where can I download the LS996ZV9 for the Gflex 2 (Sprint)? I can't find a KDZ nor TOT :(

I hope someone could upload a KDZ to flash and have the lattest update. My Gflex 2 is currently on LS996ZV5, I'm outside the US so I can't get the update from Sprint.

Please help :)

- Leonardo
[LG G Flex 2] rAndroid3:
There is not KDZ or .TOT for zv9 yet. But it doesn't matter u r outside USA, are u rooted or what?
[LG G Flex 2] Sw33t_Lov3r:
Help me updating my Gflex 2

Hey! Thank you for your reply.

I just want to update my Gflex 2, not interested in rooting it at the moment. It's on the olv V5 and the latest is V9

It's stock Android. Not rooted.

How can I do it?

I've seen there is a V9 image in a rooting thread. I may try it.

But I just would like to have it updated! :(

- Leonardo.
[LG G Flex 2] rAndroid3:
No way, never try to flash zv9 over zv5 or you'll get a beautiful brick. But it's odd the fact that you can't update. Have you checked for system update? What does it says when u tried?
[LG G Flex 2] ganbold:
after this flash, can i factory reset my phone?
[LG G Flex 2] Alex_XV6700:
Sure...

Already tried on mine and no problem.
[LG G Flex 2] informramc:
Hello,

I just bought a new flex2 LS996 from ebay India. The phone came with ZV6,rooted and SIM unlock. I am currently using it with my Indian SIM.

But with few days of testing, I feel the phone is getting overheated/performance lag during normal usage itself. I may be wrong. But I want to return to stock with ZV9 which said to be fixed some of those issues.

So my question is, if I go back to ZV6 stock and get OTA to ZV9 , will I loose the unlock. Still i will be able to use it with Indian SIM?

Thanks

Ram
[LG G Flex 2] chetveriks:
You can easily flash rooted zv9 after OTA. But there is a big chance you will not loose unlock. You will loose root for sure.

Remember to use equal stock ZV you have now installed.

BTW I have had the same phone from USA. It was unlocked with zv6. After OTA it was always freezing. Whatever I done to it nothing helps. Now it is a hard brick.
[LG G Flex 2] informramc:
Hi

Thanks for the response. Currently I have received an OTA of 117mb or something, which if I try to install failed(obviously) as I have root.

I am ok to loose the root, but not the unlock. In case after returning to stock and ZV9 if I loose the unlock, is there a way to unlock it again?!
[LG G Flex 2] chetveriks:
Yes. U will be able to unlock. Just DD rooted zv and change files in carrier folder again. Look thread with instructions for zv6..zv8. Search in last post there is a link to download rooted zv9
[LG G Flex 2] informramc:
Thanks again, let me try this.
[LG G Flex 2] zoundguy:
Well, awesome, after a year with this phone, and being very careful with it,I finally bricked it.

if there is any option I'd love to hear it.

I flashed the zv8.TOT and that worked, but I wanted to then flashed this zv8.img. (so I could install zv9).

This has resulted in a black screen with blue flashing light.

I can enter Download mode, the computer recognizes the phone as being on port 41, but the LGFlashTool just waits for connection (regardless of whether or not I plug it in or not).

I guess I stilllll dont understand post #89

anything else I can DO? besides sending it back?
[LG G Flex 2] zoundguy:
Flex is back. Holding off on rooting in case marshmallow comes out this week or next. But I am mildly curious while it bricked in the first place. I flashed the zv8 TOT, which was rooted. So I thought I could use the zv8 IMG to return to stock (unrooted). This is what bricked me. For the future, what should I have done to return to unrooted?
[LG G Flex 2] ndubat@gmail.com:
please how do i transfer this file to my internal memory? ls 996 on zv9....the phone comes on but then i get "...phone not responding"...hard reset with volume down and power does not work....and am at a loss what to do......i am re-downloading zv9 stock image but it seems it has to be transferred to my internal memory before i use L.G Flashtool....
[LG G Flex 2] Alex_XV6700:
Not really... You could flash the zv8 tot and then transfer zv9 sys image and update... That could work. I dont have the phone any more and I am going to delete the stock system images they are taking my personal space. I hope you can fix your phone. :good: good luck

Before you delete those stock images, give me some time to get them, I'll mirror them myself on a site, a few hours if you don't mind, then I'll provide links you can edit back into the original post.

Then head over to one of the unlocking threads since this one has nothing to do with that, this one is strictly about returning to stock using the .img files in the OP.
