I have been searching for hours to no avail. Does anybody know of a way to restore stock recovery over twrp? I finally got around to rooting today with ioroot and used autorec for twrp, but almost immediately after doing so ZVD update hit my phone. I want to take the update, but don't want to do a full tot restore if I don't have to.
I don't know of a way to flash the stock recovery over TWRP. I would imagine somebody has figured it out. But I do know the OTA's are extremely sensitive and they check for more then just the stock recovery. Back when the ZVC/B update came out I hadn't even flashed a recovery yet, just rooted, and I unrooted and took it and it didn't work. So I'd copy all your belongings onto your computer, make a back up and copy it on your computer as well. TOT your phone. Update. Then come back later and put your files back onto your device and use Titanium backup to take your apps and data off of the backup you made.
Maybe somebody else know of a different way. But you can brick your phone taking an OTA with system modifications, and that will be a whole lot more work than rooting and flashing a recovery again.
Good luck! :good:
Oh I know its a lot of work. I got this phone from a guy who took the zvc update while rooted and it was stuck in a boot loop with download mode unavailable. Fortunately the great resource that is this forum had the information available to get it going. I would like to not do that again. I have everything backed was just hoping to find a way around it.
Thanks for your reply.
I'm going to be away soon and won't have easy access to a non-professional PC (meaning any computer I may have access to - I won't have admin rights with). I didn't want to wait for a root+TWRP dev package for Lollipop to be released. I wanted to just get it done, (I was having bad problems with KitKat on some select apps because of LG's 4.4 coding, long story, but I won't even go there...)
I saw that I can go to the LG support site via a link from Android Central and manually upgrade to Lollipop way before the OTA rollout even begins. I had heard rumors of people having problems, read posts, and learned how to avoid it all. I reset everything before upgrading. I did many factory resets after getting Lollipop, (I know, a lot). I got rooted and set mostly everything up.
I wanted to get Xposed loaded, BADLY. I looked it up for Lollipop and realized that I'd have to flash a custom recovery. I expected as much. When I looked that up, I realized that I would have to either use a downgrade-upgrade method (which I didn't feel like going through) or a mandatory requirement of factory reset though a process. I had already set up all of the system stuff and restored from Titanium backup most of my apps. There was no way I would factory reset because I hate resetting-up the system stuff. - - - - - BIG MISTAKE 1
So I found a thread for the D850 (AT&T) version (no I didn't flash a bad radio or anything, I thought I knew what I was doing because I was only flashing recovery stuff for Lollipop, not an AT&T rom or radio.) This was to install TWRP without downgrading or resetting. The instructions said to copy files from an aboot.img and other boot images and such (to replace the recovery) on to the internal memory and use a terminal to type in code. I did it and rebooted it.
I made a horrible mistake.
When I held the power button on the phone, nothing happened. I found out that when plugging it in to the PC, it seems to be in download mode. It was fully charged. When using the restore/brick recovery software, I have tried different cables, different computers, checking to see if anything is corrupt, different USB ports, etc. with the files... Nothing will work. I keep getting an error with a red box about the model or something. "Model Information Check Fail"
So basically I have broken boot images on my device. I need to fix these.
Where do I go from here? All because I wanted Xposed on Lollipop without resetting.

I have this situation. I messed up with laf.img and aboot.img too (from D850, thinking it was harmless since trying to install custom recovery only) and device won't turn on but PC recognizes as download mode but can't flash. Please read above. I'm bricked and all restore methods have failed so far.
Source from u/nicksteron on reddit.
I'm having this issue now too. It seems the thing I downloaded and tried broke my boot images.
Have you been able to fix this?
I'm trying the LG Flash Tool but it stops me at the model check fail as well. Gonna try a kdz method next.
EDIT: I tried the KDZ method with LG Flash Tool 2014 using both a KitKat and Lollipop based ROMs and I get an error. The S/W Upgrade progress gets to 4% and then the error shows up. I need my phone. Help?!
Ok, here is my dilemma. I panicked a bit and downgraded to KitKat 4.4.4 from Lollipop 5.0.2 while there was some concern over it killing N7's. As is usual, I rooted the install, which means the 5.0.2 OTA will fail to install.
In the meantime, I started playing Agent Alice. (Don't laugh, I like hidden object games) However, unlike most apps, backing it up in TiBu doesn't preserve your progress. If you restore the backup, you start out at the beginning. I'm not sure how or why, but it appears I can't do my standard backup and push to the server routine. Which means I really don't want to blow away user data.
So, I looked into using the factory restore images with the modified flash-all.bat. I haven't yet pulled the trigger on that, because I have been told that going from KitKat to Lollipop without clearing user data can cause problems. I'm tempted to use TWRP to back up the whole thing and give it a go, but I'd prefer to go in as well-armed as possible.
What's the best way to get from KitKat 4.4.4 to Lollipop 5.1 without losing installed apps and user data when an OTA isn't an option?
I used factory images with a modified batch file to go from 4.4.4 to 5.0, then 5.0 to 5.0.1 and 5.0.2. I haven't updated to 5.1 yet.
I didn't lose any data. I installed the factory images, booted once and then ran Chainfire Autoroot each time to get root back. Zero issues, no lost data. As long as your bootloader is already unlocked (assuming it is if you're rooted and have already flashed back and forth), you won't lose anything.
You could still make a nandroid backup and worst case, flash factory images back to whatever version you did the backup from, restore and try again.

EDIT:Thank you everyone for your support in this thread and to those that donated. This thread actually got me the first donations I've ever received just for tinkering around with phone operating systems; super cool. However, I will no longer be actively taking feature requests or looking for/fixing bugs as I have succumbed to the allure of the V10 and have retired my beloved G4 in less than a year of ownership. I must say the V10 is a gorgeous phone and I absolutely love it. I will continue to frequent this thread and answer any questions and offer any help that I can give to help anyone who may need it. My G4 is now on eBay (until Sunday) so if anyone is interested in a MINT condition Verizon G4 with a LOT of extras, PM me and I will give you the link listing as I believe posting it on here violates xda policy. Now time to explore the V10 forums. Cheers all!
_______________________________________________________________
Fellow Big Red G4 owners,
I am providing for everyone a ROOTED BEBLOATED 13B system image for the Verizon G4. I was on 12A rooted and the OTA to 13B failed so I flashed the stock 12A image that I had laying around, took the OTA successfully, pulled a stock 13B image, used the root injection method found in these forums and flashed back. I can confirm this works!! I'm running it on my phone right now. This system image is also slightly debloated. No, I don't have some fancy program that can open the system image files and pick and choose what I want to delete. All I did was boot my phone on the rooted 13B system and use root explorer and root uninstaller to remove a bunch of stuff that wasn't needed. I made a few other changes as well. Once I was satisfied with my debloating I extracted the system image again and am sharing it with you all! Below is a list of the changes I made as well as the download link. WARNING!!!!!!!! I AM NOT RESPONSIBLE FOR ANYTHING YOU DO WITH YOUR PHONE!! I ASSUME YOU KNOW WHAT YOU'RE DOING IF YOU PROCEED!!!!!!
EDIT 1: I put the img file in a highly compressed rar and 7z archive so the you now only have to download a 1.74 GB file instead of a 4GB+ file.
EDIT 2!! It looks like the official 13B KDZ is FINALLY here thanks to @autoprime !!! Get it HERE.
----------------------------------------------------------------------------
The super user binaries are updated. (meaning you wont get prompted to update them on first boot.)
BusyBox has been pre-installed.
AdAway Host file baked in.
Google Chrome browser has been removed and has been replaced with the stock LG Browser!!
The following system apps have been replaced with those from the new LG V10:
SmartNotice (The best difference is that it's somewhat transparent so it looks WAY cooler.)
Calendar
File Manager
Gallery
Music
^^I was able to get odex files for the above V10 system apps so they don't have to be "optimized" on first boot.^^ Even though the Contacts and Home Launcher app are available from the V10, the Contacts app always force closed no matter what I did and the Home Launcher app would randomly pop up with a "Loading Apps..." pop-up box for about a second when you hit the Home button, so I left both those apps out.
All the VZW bloatware apps have been removed, save for visual voicemail, which I like and actually use. In response to a question I received as to why I removed the CallerNameID app, I use Advanced Calling and CallerNameID, as well as a few other Verizon apps, are not compatible with Advanced Calling according to Verizon's web-site. (See attached screenshot.)
The stock, very annoyingly bright red, could-have-been-a-flashlight-app (lol) Verizon boot animation has been deleted and was replaced with a nice, simple and unobtrusive stock android boot animation. White text on black background. Much better.
The DPI has been set to 560 compared to the stock 640. It will go as low as 540 with no FCs but 560 is just about perfect for me. If you don't like this size, use Textdroider app to change the dpi. NOTE: The only stock app I have found that doesn't work with this lower DPI setting is the LG Voice Recorder. It doesn't work on any DPI setting other than 640 (not even 639). However this app is still included in case you wish to revert back to stock 640 DPI and use it.
-----------------------------------------------------------------------
First boot after a factory reset using this image will be really quick as it will only have to optimize 2 or 3 apps instead of 20+. If you don't like anything, such as the DPI, or visual voicemail, etc, you can change whatever you want since you'll be rooted. This is just how I like my phone.
YOU MUST have already taken the 13B OTA and you will need to be un-rooted to take the OTA. If you are on 11A or 12A rooted, the easiest way to un-root is to use the 13B KDZ to reset your phone to factory un-rooted stock. If you use the KDZ method be sure to backup your personal data as flashing a KDZ will wipe all your data.
You can follow the instructions on how to flash the system image HERE. You will more than likely run into problems if you are on 11A or 12A and try to flash this image without having first updated to 13B using one of the methods listed above (OTA or KDZ), so don't even try. I will not be able to help you get out of that predicament.
You can download the image file HERE!! (RAR Archive format)
Same image in 7z archive format HERE due to several users have MD5 mismatches with the RAR archive. (Needs free 7-Zip archiver program to unpack.)
The MD5 of this file (the IMG file; not the archive files) as it sits on my desktop is 1eca2a177f50f4a092bc5ef0939a99a7
Another thing to remember. Once you flash this image, there is no going back to the state your phone was in before (stock, un-rooted) unless you have a backup of your current system image. Meaning, even if you do a reset to factory defaults from the stock G4 recovery after you've flashed this system image, the defaults it will go back to are those of this system image.
IMPORTANT!! Resetting to factory defaults using the stock G4 recovery after you have flashed this image will NOT un-root your phone. You will have to flash a KDZ file to get back to stock un-rooted. There are instructions on how to extract your current system image HERE before you flash my image.
CREDITS
HUGE thanks, kudos and all credit for the LG Browser goes to @xdabbeb. I was never able to find a new version of the LG Browser that would work on the G4. I asked xdabbeb to see if he could get it working for me and he was gracious enough to do so; thank you!! I became hooked on the LG Browser being a long time fan and user of his ROMs for the Verizon G2.
Thanks to @BySezerSimsek for the V10 system apps. His thread with all the apps is HERE.
I do not take credit for any of the methods used in achieving this. All credits for superuser scripts, injection methods, ported V10 apps, etc goes to the appropriate people. You know who you are. I'm not a developer by any means. I'm just a power user who's not afraid to take the plunge and follow instructions from other very respected users who give all of us the tools we need to make our phones what we want them to be. Without these people, we would have very boring phones. lol. This is the least I can do to contribute back to the community who has helped me out in so many ways.
ENJOY!!!!!!!!!!!!
will give it a try in a few. I dont see clear instructions on how to pull my own system .img for back up purposes
Edit: I guess if i look i would find it. HaHA, to early in the morning to be reading XDA!
Anyone tried this yet?

Nope, keeps failing. No worries. It's fairly new. Give it some time to work the kinks out.

Within the last 24 hours I believe. I just checked for an update this morning via WiFi and got/installed it.
https://www.reddit.com/r/lgg4/comments/3u3nfo/verizon_update_1124_wifi_fix/
I was on 11A and the 422.1MB download took me straight to 13B .
Any pointers for this VS986 + forum newbie on how to root 13B greatly appreciated .....

Again, like the 12a rooted image, there is no coming back from this if something goes wrong. Maybe someone could write a short step-by-step for those of us who want to make a personal backup of our system.img, and I really need to go find the instructions to flash the pre-rooted image since that was so long ago now. Really happy to see this though.
ps.- the download worked fine for me.
I second his advice to create a backup of your current system.img. If you don't you will need to factory reset again when you want to install another OTA, that's what happened to me. No matter what I tried, the OTA would not install on my system.img, even after I unrooted etc. I think I also went too far with moving system apps to the SD card and freezing some apps which prevented it from installing.
To install the OTA on a rooted VS986, is it necessary to flash a stock image (kdz), or can we simply unroot via SuperSU?

On 11A as well.
I'm pretty fed up with this phone, so when I get home I'm going to kdz 11a stock with LGUP tool, factory reset, take the 13B OTA, back up the stock system image, then inject root and see how that runs.
Then I'll probably flash the debloated image later this weekend.

The update will not install if you are rooted. You can try, it will go through the motions and throw an error.
If you KDZ, make sure you use the KDZ of the version you are on. If you are on 12A and flash the 11A KDZ, you will brick your phone.
The proper way to do this is to BACKUP YOUR SYSTEM.IMG BEFORE YOU DO ANY ROOTING so you can just restore your original system image and restore back to out of the box experience.
If you did NOT backup the system image, then I would recommend looking for a STOCK UNROOTED system image of the same level you are currently running. Push the system.img back onto your phone, take the OTA, BACKUP, and push a rooted system image.

My plan, too, but without the debloated image. Backing everything up now....
I don't have the original stock image. Can anyone provide a link to an 11A stock image?
Sys img Bkup command?
Is this the correct code to run a backup on my 12a unrooted stock, using the LG Root.zip?
dd if=/dev/block/mmcblk0 bs=8192 skip=65536 count=548352 of=/data/media/0/system.img

Thanks. Maybe I mistyped. What I meant is, the stock image we pull off when we first root. I deleted mine. Is KDZ the only way to go or are the two essentially the same?
usr folder
Hello Everyone,
I was wondering if anyone could pull there /system/usr folder from 13 and upload it?
I'd like to tryout the new idc to see if that resolves the last of my touch issues on 11A
Thanks in advance,

I don't remember backing up system image as part of the Low Effort Root procedure. I will go check, but if it wasn't in the steps, I didnt do it.
If it was, I should have it somewhere.
I do have the original 11a stock rooted image saved. But that won't do me any good.
How is the system image backup accomplished without root? It is probably in the Inject Root thread.
I rooted my att LG g pad x 10 with kingroot and everything was working well until I ran the su-me software to remove the extra apps kingroot added to my device. I looks like the sume app got about 75% of the way through before finally freezing. After rebooting I can now only see the clock and the virtual buttons at the bottom of the screen. I tried to use the lg tool to download the firmware and reflash the device but it says Im up to date and wont reflash it, How do I wipe this back to stock and start over Im sure this is because supersu and king root had conflicts. Is there a way to get the att firmware and force it to reimage the device?

You could follow this thread to restore your tablet.
That's a pretty complicated fix. I'd try a factory reset in the stock recovery just in case to start with.

I need the firmware to restore the backup. I have no problem performing the restore but I cant find the firmware they do everything OTA, If you can show me where the firmware is Id owe you. Im going to try to return the tablet but its got king root on it figures the one screen you can get to is settings and installed apps and since kingroot is a system app I cant remove before returning.

This thread links to a kitkat kdz. It resizes some partitions though. To get your full storage back you have to follow the procedure in that first link.
It's the only full firmware package I know of for the v410. Since you're on the lollipop bootloader it's the only fix I know.
i used that KDZ to fix my LG G Pad 10.1 -- and that s why I am now looking for an actual KDZ or the 10.1 -- that file left my 10.1 DEAD. DEAD. QSHUSB_BULK is what it shows now in the device manager and there is supposedly a fix -- but this forum is waaaaaay bad for these. Most software and help is NOT for the 10.1 -- be careful.
