LG V20 H910 Root attempt fail, any plan of recourse? - LG V20 Questions & Answers

Hi. I'm just gonna say this first: I didn't know entirely what I was doing when beginning this operation. I was just trying to do something fun and new, and it didn't pan out. I fully acknowledge that I am an idiot.
Now, the story. I was attempting to root my LGV20 with this guide: https://forum.xda-developers.com/v20/how-to/root-h910-v10m-t3664500 .
I have read over this thread more times than countable and thought I was doing everything correctly. I got to the "STEP3.BAT" portion of the guide and long story short, my phone crashed during it and somehow got foobarred.
It *kinda* works (as in it will boot for around a minute) and then blue/black screen into a reboot.
Is there any way I can save this phone? Hard resets, going into software, more dumb computer stuff, anything. I don't *need* to get this phone working again but it would be really preferable.
Simultaneously I fully accept the responsibility in failing the operations. I know that somewhere I must have messed up. If no-one wants/ can help me, tell me so. Just means new phone time.
If any more detail on what happened is needed, tell me.

First off: that guide is ONLY for the H910 (AT&T) variant, so make sure with your model
and also, when you said a "blue or black screen" it also has very small writings too, right? If so, then you may have faced a kernel/bootloader panic
Technically your phone is *still* alive, and your best method is to start over again, assuming if you read the whole guide carefully then you have backed up your firmware and can still access download mode.
Flash your stock firmware back (or use the H915 firmware provided by the guide), wipe and setup your phone again, then root the phone again.
I also suggest replacing the TWRP recovery inside the provided Dirtysanta folder cuz that's what i did when i faced the kernel panic

Thanks so much. Freaked out over this for a good bit. Came back, did what you said and we're back at that step fully working. Life saver.
Now my first guess as to why step3 failed is that i didn't have the latest version of TWRP. How can I set that up?

Inside the root package folder you can see an .img file named twrp 3.0.2-1- us996.img
What i did was downloaded a later version
(not latest cuz my phone won't boot at the latest version for some reason), copied the name of the original twrp and renamed it, paste it to the folder, overwrite the old one, and try to root it again

Alright, i've done that now too. Thanks. Is there anything else i should/need to keep in mind to ensure failure is not going to happen? I want to make 100% sure I get everything right this time.

No i don't think there is more things to do, the guide you're following is pretty much straightforward already.
100% guarantee is always a stretch here in XDA. But if you're still facing problems you can ask for help on that guide's thread.

I really want to give up on this. This time I successfully made it through all Step 3, but I also noticed that my screen was kind of glitched and not rendering properly at that stage. After it rebooted, I unplugged my micro usb cable and it gave me an angry green warning message I will attach here.
If you/someone can tell me what to do with this message from here or instruct me on how to flash stock H910 10 q back onto the phone without doing TWRP (since i'm evidently incapable of installing it) I would be most appreciative.

Slightly better picture without anything cut off.

The screen glitching is normal, the green text after boot however is somehow not.
Sad to hear that it still didn't work, there something seems to be interrupting the process of rooting your phone. I dunno if it has something to do with ARB (anti rollback) preventing you to root
If you want to go back to your stock firmware that you backed up, you can:
-Carefully flash each file of your backed up firmware through adb and fastboot mode
-build a zip file of your firmware and flash through TWRP (since it didn't succeed tho)

Unfortunately i can't find any guides when it comes to flashing the back up.
I did read something back then on turning it into a zip file, but even if you can build one you still need TWRP, in which case you haven't successfully installed, so that's no option
Flashing the backup files requires specific commands, especially to the part on what partition should it be flashed to
When LGUP backs up your phone's firmware, you can see a vast number of files(i can't remember how were they named, I'll look up a reddit post about it)
The files where named based on what partition it came fom (H910_modemxx_COM12, H910_system_COM12 or something like that)
These are image files, what i did as far as i can remember was rename these files by adding an IMG extension for ADB to recognize
Flash them according to it's partition name:
"Fastboot flash system H910_system_COM12.img"
"Fastboot flash recovery H910_recovery_COM12.img'
Etc.
To go to fastboot, turn off your phone and hold the volume down button , then plug your phone to the PC.
But i really cannot guarantee this, because for all i know, in order to flash this you need fastboot, and to get fastboot you need to root your phone, because only the engineering bootloader has it (i'm sorry if it's wrong tho), and flashing these files to fastboot might be a bit dangerous because it will not verify the files, there may be chances that you might flash a corrupted file. so flashing via LGUP is the safest option so far if you don't know what you're doing

[Q] Xoom files doesnt change

Hello guys,
i got a serious and frustrating problem here.
A few days ago my xoom was stuck on the M screen, so I used a thread in the forum and recovered it.
It solved myh problem back then, but since I had 3.2 before this and the solution injected me with Android 3.01 my problems started to show themselves.
the first one is that
<b> Through Fastboot, RecoveryMod, ADB </b> and any other way you can Imagine to install a new ROM or even remove or create a file,
All of them show success message but when I check them out I see no changes.
i tried fastboot and Recovery to install nearly every ROM,Recovery and bootimage in this site but so far it was wild goose chase.
so I want to ask if I'm doing anything wrong or if you need any more information here, but please help me with this
wow I cant believe it, All these masterminds here and no answer to my distress signal??
Guys I am so in trouble and this is the only place I hoped to get answered.
I can provide you with more info if you need, but please dont say I'm on my own here.
all these years this forum was the last hope for me.
i know I'll get my answer here one day
You are not being very clear about what you have done,, but I'm assuming that you reinstalled the stock image that got you back to HC 3.01. Can you see if you are able to get OTA updates to get you back to at least 3.1, or 3.2 if possible?
If that's my problem forgive me please, Ive written that post in 3:00AM
for the sake of clearity I should add some info:
1. I even tried stock ROMs but you see I cant even flash them (Not from Recovery nor Fastboot) the steps seem successful : it opens the package,it installs them and it says everything was a success. But when I restart the device I see nothing has changed.
2. OTA updates are the same, they keep downloading and when the sysem reboots to recovery to install them it cant find them.
3. You dont believe it if I say even files and programs that I remove from device by my hand(Android OS) are back after the first restart.
And you see it's dark magic! everything from a file to a partition are back by one reboot. I dont know what should I call it but I havent seen anything like it on the whole Internet.
So seems like I should make a competition for the xda experts here
Can you publish it so all of them can see it?

Actually, I have seen someone with the same problem here on this forum, but I can't recall exactly what the solution was.
Can you describe, step by step what you are doing, what cable you are connecting to your pc with, etc?

That would be relief to know this could be solvable.
I will look more too.
As for your post I must say:
1. I plug the Xoom to the PC using the included cable
2. I start the xoom and start fastboot
3. on the PC system has the drivers and completely knows it
4. I start with SDK:
I. Fastboot oem unlock (Completing onscreen instructions and reboot device)
II. Fastboot mode again I use Fastboot flash boot boot.img
III. Continuing with Recovery,System
IV. Rebooting the device anything is the same.
My ROM is unchanged by the process and keeeeeeeeps giving the damn error of System process error please submit
5. And with ClockworkrecoveryMod I have the stock ROM on my sd card.
I. I choose install zip from sd card.
II.Choose the correct zip file and start flashing.
III. Choosing Wipe Data/Factory reset will take the device into a complete hang. unless I first use the mount page to mount the System/Data
IV. I reboot the device and ..... you know nothing changed.
so thats my story.
Still hope to find something about it.
Thanks...that was helpful. But now I want to know the following:
Were you rooted before the trouble started?
What did you do to recover?
If rooted, what version of CWM recovery did you have installed? Did you do a nanadroid backup? (I guess the answer is no, because you could have just restored with that).
What recovery are you accessing when trying to flash a zip file?
If you can answer these questions I will continue to wrack my brain trying to recall where I saw that thread.
Edit: please check out this thread http://forum.xda-developers.com/showthread.php?t=1370312
Some of what I said to him may help you .

I was thinking of may be the userdata partition is corrupted and I gotta find a way to flash it completely.
Somehow I used Fastboot utility to do this and after saying Success, Nothing changed again.
Do you know any other way to physically do this job?

[Q] After 4 1/2 yrs on XDA I am finally stuck! Bricked No download mode, No OS.

Hello my fellow XDA Members. I am stuck in a tight spot and after reading and re-reading some things the situation doesn't look very promising. I hope this is the moment that Karma shows up and I can get some help on this. Here it goes.
Specs - LG G2 D801 Variant > TWRP V2.8.3.1 > NO OS Currently
I was running Cloudy G3 Rom smoothly and got bored and decided to flash that new rom that is a 5.0 Rom all variants. Did the usual back ups and flashed it. Something happened when I flashed the rom. It went through the Aroma installer and then said "successful" but stuck in a bootloop. I tried it again and nothing happened. Then I tried to wipe everything again and started getting an E: Cannot mount (data or system I forget which as that error went away after I completely formatted data, wiped everything and reflashed Cloudy Stock. )
> Cloudy stock bootlooped and nothing is happening in TWRP. I Am using the USB OTG method of getting files on the phone and getting it charged but anytime I try to do anything (flash a rom, an older version of TWRP) it just immediately restarts TWRP and thats that. I have No OS at all.
> I tried to use one of the methods to get into download mode and flash a stock KDZ but the phone acts like it is going into DL mode (shows the little blue transition screen) but never gets into the ACTUAL download mode where the PC or flash tool can recognize it.
So in a nutshell > No OS > I can get into TWRP but it does nothing > No Download Mode > Don't want a new phone > Don't want to take it apart and try to short circuit anything if possible. LOL.
I am totally stuck here. I am done alot of work and even helped friends and family out with their devices over the years. I am just not sure if I need to consider it a done deal and get a new phone or maybe one of you guys know of something easy and obvious (please let it be the latter) I am missing. Thanks for any help you can offer. I Will be standing by.

I haven't thought about flashing a bootloader. How would I flash the bootloader if I can not the phone into either DL mode and or TWRP doesn't do anything either? Is a bootloader file just a flashable file like any other .zip file?

The first one I can not do as I do not have any knowledge at all of Ubuntu, Linux, or any of that. It would take forever to get a working knowledge of that software in order to get things going again. I would probably just have to either take it to a cellphone repair shop or get another phone before I could do the first link.
I have not tried the second one but it is a viable option. I was looking at it online and trying to talk myself down from having to do that. I would reallllllllly rather not have to take my phone apart if I can keep from so that's kind of what this post is all about. Just trying to see if anyone knows of ANYTHING else before I go taking apart my phone.
Can you describe more about "twrp doesnt do anything"?
Does twrp boot up?
Can u see/wipe partitions?
Can u install any rom in twrp? Does it finish?

TWRP boots and I can go into wipe, advanced wipe, and format data and it says it's successful. I can use file manager and move items back and forth from USB OTG. If I try to flash anything it just reboots TWRP immediately so I can't install any .zip files at all.
My guess is that your bootloader is damaged.
The only option i can see for you is that Ubuntu thing i shared with you. So, lets stop acting lazy and do what needs to be done. Dont scare since there is nothing to loose. LG G2 is unbrikable
Booting up ubuntu or any other linux os is so easy. And there is nothing much to learn. Trust me.
Go to ubuntu website and download their newest iso file. Burn it on dvd and boot it up. You dont have to install it, just choose "live mode" and it boots up. Just like that. Then yiu can proceed with tutorial mentioned above and it shouldnt take more than an hour from you. Its all typing some commands in terminal (remember CMD in windows!).
Just make sure to download the files mentioned in that tutorial before proceeding.

First of all calling people lazy is not nice. I'm not lazy I am trying to play it safe. I wouldn't want to brick it to the point to where I don't even have recovery and it can not even be charged any longer. I have Ubuntu on my desktop upstairs. I have used it a little. It's not that I am completely ignorant to Ubuntu I am just a total novice. Also the issue described in that post doesn't exactly match my situation. I am not in a black screen. It's more like a bootloop that I can not get out of because TWRP is not doing what it needs to do and I can not flash TWRP a ROM or get into DL mode at all. Also that post says,
"VERY IMPORTANT!!!!!!! You must use the img files that correspond to the ROM you have installed before getting the problem to avoid breaking your phone."
I don't have a rom on my phone soooo...
You didn't answer my question well. If on TWRP you can finish installing rom without any error, and you keep coming to twrp after restarts, that's another situation. Try this:
http://forum.xda-developers.com/showthread.php?t=2451696
But if you cant even finish install in twrp (twrp gives you errors or just restarts before giving you "successful", either you have problem in rom you try to flash or you need to build everything up from start.
That lazy thing was for encouraging you to do it.
And you cant brick your device. There is always a way on G2.
For img files: find them from last stock rom that was working on your phone.

[How To] Root - Backup - Custom Recovery - Blu Studio C (D830U)

What you will need:
KingRoot V4.5.0.901 (latest version as of this posting)
Rooting your phone will void your warranty.
Terminal Emulator for Android
Replace KingUser with SuperSU
MtkDroidTools v2.5.3-updated
adbd Insecure v2.00
SP Flash Tool
I am not going to get into how to install ADB drivers, MtkDroidTools, or SP Flash Tool. If you are not experienced with rooting, flashing, etc., please do some research.
Okay, let's get started
First you will need to get your phone rooted. Download KingRoot using the link above and follow this guide.
Next you will need to replace KingUser with SuperSU.
Now that we have the phone rooted and SuperSU in place, we can use MtkDroidTools to make a backup of the phone.
This video will show you how to backup your phone with MtkDroidTools (make sure you have downloaded the version I provided, as this has updated ADB files). Also make sure you enabled adbd Insecure before you connect your phone (you don't need to check enable at boot).
Once you have a successful backup, you need to create the files for flashing (scroll down to PREPARING EXTRACTED MTK ANDROID FLASH FILES FOR FLASH TOOLS) if you need to flash back to the original firmware.
Hopefully you now have a backup of your phone. Now we can install a custom recovery. You can use either TWRP (rename to recovery.img) or PhilZ.
The easiest way to flash the custom recovery is with SP Flash Tool. Connect your phone (you don't need adbd Insecure enabled for this). Run flash_tool.exe as administrator. For scatter-loading File click on the Scatter-loading folder
and navigate to your MtkDroidTools backups folder. There should be a folder that starts with BLU-STUDIO-C. Open that folder and select MT6582_Android_scatter.txt. For the recovery file, navigate to the one you downloaded (TWRP or PhilZ) by clicking on the Location column next to RECOVERY.
Make sure RECOVERY is the only box checked before proceeding. Now you have your scatter file and custom recovery loaded. Click on the Download button. Nothing will happen at this point. Now shut down your phone (not restart). Once your phone shuts down completely, plug it in via USB and you should see it begin to flash the custom recovery. If not, then you need to make sure you have the necessary drivers installed. Once it's complete, you can close out SP Flash Tool and disconnect your phone. After your phone is disconnected, hold down the power and volume up buttons until the recovery menu appears :good:
Post your feedback, and if you encounter any problems, please be as descriptive as possible. Good Luck

Thanks for this guide, it has worked for me so far (backing up with mtkdroidtools now). Can I ask, why is it neccessary to use SPFT to flash the recovery? I have used fastboot to flash the recovery without issues. I just
$ fastboot oem unlock
and then was able to
$ fastboot flash recovery recovery.img
and it worked.
html
Also, would you be able to port some custom roms for this phone?

Glad it worked out for you. Yes, fastboot is also an option (as you all ready know).
Recovery could probably be flashed with Flashify, but haven't tried it. I am not a developer, so no I can't port any ROM's, and take no credit for the custom recoveries listed here.
If someone can post Cyanogenmod for a phone that uses the same hardware, I can port that for this phone.

Bricked Blu Studio C (D830U)
Hey,
Was wondering if you could help me out here, as I'm a TOTAL Noob when it Comes to BLU phones But not to flashing....
I've Bricked by Phone, The Computer and SP Flash Tools still recognize the phone..
I've Downloaded the proper ROM from NeedRom.com....
My Issues:
1. Can you Verify WHICH Driver I should Be Using for a FULL either Erase/Download Or a Firmware Upgrade (Not Sure Which)
2. I need a Scatter File the Contains ALL the Memory address and Supplies ALL the Check Marks for a FULL Rewrite Flash....The One with the rom is missing Preloader Android, Cache, and usrdata...
When I did JUST the Scatter file flash attempt I got the BROM_ERROR : S_DL_GET_DRAM_SETTING_FAIL ( 5054 )
I googled that and it said the Perloader wsn't right So I added the Perloader (And checked the "firmware.info file" and seen the Memory:
preloader 0x0000000000c00000 0x0000000000000000 2 /dev/misc-sd
So I tried Anyway and got the same error except this time it's 4032.
So Basically Can you tell Me Which Files In the ROM I Download Go Into Which SLOTS on SPFTools, and Which memory address' are correct the firmware file or the Scatter??
I really don't want to keep slamming the phone with "STUFF" and REALLY screw something up, I think I'm lucky it's even being recognized at this point....
Also the MTK_Allinone_DA.bin that comes with SPFTools is the right one??!?!
I'm Using Version 5.13.52.200
I'm Assuming Just a FULL Scatter file would solve the problem?!?!?
ANYHELP In this Would be VERY much Appreciated....
Thanks
Mike
EDIT:
Ok, I got it to 4001 Error, And it's saying that error is it's not connecting with the preloader, So I'm thinking (hoping) if I can get those 3 files, even if the cache is empty as long as the memory address is right, and the scatter.txt, and do a Firmware upgrade, Hope, will solve the problem, if not, On to Test Pins...
@bobl61
Could work together to enhance MTKDroid liek as
Increae number of CPU recognize by it (ex. MT67xx - just recognize it - not work with it)
Update the apk included and sued by MTKDroid (like MobileUncle/Root Explorer/SuperSU)
Upload the ROM or the link I think I know what's the problem @Miker1029
Fixed from the dead!

Hey Thanks, I've made some progress today, The rom is on Need Rom.com so best to just google Needrom and D830U as It's internal search doesn't work so well....
I Got a New (Cheap, Used Phone) and to my Suprise It's an MT65XX Chip set Also (ACK!!!!!)..................... NO WAY IT JUST BOOTED UP!!!!!!!!!!!!!!!!!!!!!!!!!!! TOOK FOREVER!!!!!
Ok I learned that with the Downloaded ROM from Needrom, You Need to Go to MTK Tools and Process blocks for flash, The go to the Directory you Extracted the ROM to, And It'll bring up the MD5 file click it and It'll create the Scatterfile and the "!FLASH" Directory, Then Navigate to the !FLASH (something) Directory and you'll have your scatterfile.txt, Load it up, I added ALL files (see Screen Shot) and it's booted up.... You need to use Preloader Drivers for it, And I HAD TO FORMAT AND FLASH.... And what you see in the SPFlashtool screen shot is what I flashed....
I'm not a GUIDE writer sorry, But Hopefully this will give hope to those like me (that have been bricked for ALONG TIME) Hope.....
If anyone needs info on this Ask, I'll try and answer.....

Ok I learned that with the Downloaded ROM from Needrom, You Need to Go to MTK Tools and Process blocks for flash, The go to the Directory you Extracted the ROM to, And It'll bring up the MD5 file click it and It'll create the Scatterfile and the "!FLASH" Directory, Then Navigate to the !FLASH (something) Directory and you'll have your scatterfile.txt, Load it up, I added ALL files (see Screen Shot) and it's booted up.... You need to use Preloader Drivers for it, And I HAD TO FORMAT AND FLASH.... And what you see in the SPFlashtool screen shot is what I flashed....
I'm not a GUIDE writer sorry, But Hopefully this will give hope to those like me (that have been bricked for ALONG TIME) Hope.....
If anyone needs info on this Ask, I'll try and answer.....

Update, Just a Heads Up I'm Assuming from Googling around, that Installing the NVRAM will wipe your IMEI, Still working on this aspect, But it doesn't seem to be Hindering the phone in anyway, As I said It Took along time to boot up, So I'm not sure if Re-writing the NVRAM made it work or not, I do know I formatted + Download, and It Sat On the Splash Screen, I shut down and Flashed just the NVRAM file, and It booted.....
NOW Should I go for a Custom Recovery??? LOL.... I'll wait.... But now that I know I can Fix it......Hmmmmm

You are correct. I didn't realize the video on how to backup the stock rom did not include the next step which is to create the files needed to flash with MTK. Good catch, Miker1029 :good:

Hey Thanks, Maybe you can redo it or whatever, I was bricked for Months (Mainly Because i didn't know the Phone Type), Check out the screenshots to see the extent I went to Googling My Butt Off trying to figure it out, But once I did, All went good, I've flashed Atleast 100 Phones, For me, Friends, Family, Never had the Kind of issues I had with the MTK Chipset...
But now that I have it, It's rooted, Flashed, Xposed Framework Installed and working, Exactly what I was "Originally" trying to do....LOL, It's good now tho...
Now Funny thing I lost My Compass on it, and Sensor detector says it's working fine, So Not sure what's Interfering With it.... Hate to Re-Flash
SOOO, If I GOTTA re-flash Been looking around for 6.0 (Marshmallow) Build for it (No Luck)
1st Pic, Just the Face.
2nd Pic, Where I Cut the Battery Connector (Casing) to the Board so I could Disconnect the Battery without taking the phone apart....
3rd Pic, I left the screws out as There's a Little spring on the Bottom-Left (Looking from the back) that Makes the speaker work, And On the Bottom-Right is the antenna connection that I can't get to "Snap" back in..... So I left the screws out to fix those minor issues, I'm trying to NOT open it anymore then I already have LOL

Little. More details would be nice..
Did you download the rom from needrom?
Did you create the flashable files from that rom?
Did you generate and add scatter file?
Did you format and flash?
Did you check device manager to see if it's using the pre drives?
Did you remove any and alll USB / MTK drives, except the pre driver?
Disd you start the flash THEN plug on the phone? Does MTK say on the bottom PRE driver?
And finally i believe my issue was some kind of lock up as the battery isnt removable so i cut the casing to access the battery connector and basically stated the flash and attached the battery connection..
Alls i can say is i was at the exact same spot as you i flashed 3 or 4 totally incorrect roms, and had that driver issue, when i finally got the proper rom and fixed the driver issue it worked, and it did take like 20 to 30 minutes for the ohone to boot the 1st time..

Also, i used the recovery that came with the rom and when it finally booted up, i flashed the custom recovery...
And if you decide to go with disconnecting the battery be careful as some months after the female connection on the board broke completely off... I hate any phone without a way to break the electrical connection think it's stupid..
Good luck,

Ok i'm going to explain my journey from soft-to-revive history:
I was trying to install a custom recovery for my D830U (Blu) and end up in this thread. I made all the steps
-Rooted the phone with kingroot
-Removed kingroot and installed SuperSU
-Instaled insecure adbd insecure
-I made a backup of my stock rom with MtkDroidsTool(wich is the needrom provided, since i flashed my phone while ago)
-Drivers are installed (VCOM)
Everything is downloaded from the links in the post
Ok at this point i did everything exactly like the guide, great
Ok now the part were "something" failed is:
I got the scatter file in the mtkdroidstool backup folder and REPLACED the recovery to the PhilZ recovery.img in the link of the first post. And flashed normaly. Here is where things got bad
I disconnected the phone and realized it got bootloop, couldnt start the phone and can't get into recovery (when i press vol+ button it goes to black screen), because i installed a bad/not compatible philz recovery.img(AGAIN ITS FROM THE PROVIDED LINK) ok now i'm worried but no problem, i tried to reflash with original stock rom and eventually after many tries i got into a normal recovery mode and the phone boots normal..
Now my phone is at the start point. Can you tell me which version of custom recovery are you currently using? Or what procedure should i follow to get into it? Again thanks! Cheers.
Ya I'll upload the recovery i used, I'll get it here sometime today..
I'm not sure which it is, as i said, the power connection for the battery broke off the board awhile ago, so it's either philz or twrp.
Also, if I'm remembering correctly, you have to add the other drivers, not the pre driver, you can try it with the pre, and if you don't get the green check use the other ones, and when you go flash, I'd backup your recovery you have now and put it somewhere safe...
Ill also add the version of xposed i used, if i can find it.. I know i had to install the. Zip files from recovery...
Mike
I believe this is the custom recovery i flashed, i no longer have the phone to test, but i believe i removed all except the stock and custom..
As i said back up your current recovery..
Let me know so i can mark it my puter.. Thanks
Mike
Also let me add, I had a bad philz also, not sure if i got it here, or somewhere else, but i have it marked as philz doesnt work on my computer...
Ok folks, two downloads, can you provide an update?
I'm trying to help with an obscure phone..
So a report back, for the people, would be nice.

ZTE Axon 7 USA Bootloader/TWRP/Update Help

So here's my story,
I bought this Zte phone off someone on craigslist a couple of weeks ago, and I've loved it every since. In fact, I have yet to turn it off, I've kept it on the entire time. Today the new update 29 came out for the US, and I tried downloading. To my dismay when the phone restarted I was greeted with a bootloader screen, and then a TWRP screen. I freaked out and panicked and emailed the guy I bought the phone from since I heard that unlocking bootloader on your phone voids the warranty. He told me he had done it in such a way OTA framework that it didn't void the warranty and also I can always relock the phone but be careful because I might brick it. I'm not a very tech savvy person and have no idea what to do to relock the phone so I can download this new update. Could someone please help me out and walk it out with me step by step so I know what to do. Thanks so much guys!
Look in the section rooms, recoveries,etc... look for one the says roms update stock DrakenFX
Since you are not tech savvy, you could just keep it unlocked and use those twrp flashable files to update B29.

However If you will wish to restore to locked state without twrp, I will be happy to guide you but you'll have many more steps to do.

If you're not tech savvy, you probably don't want to do this. It's not simple and for whatever reason, some people (who would consider themselves more tech savvy) have had some issues.
Your best bet is to copy all of your data from internal memory (just in case), flash a new copy of TWRP (recovery only, you don't need to do boot) using tenfar's tool (http://forum.xda-developers.com/axon-7/development/wip-axon-7-root-bootloader-unlokced-t3441204), then follow the steps in DrakenFX's thread to get B29: http://forum.xda-developers.com/showpost.php?p=68873482&postcount=2
I'm happy to write you a guide for getting back to bone stock, but I'm not going to do it until next week when I have time at work and as I said earlier, some folks have had issues. For what it's worth, you likely won't hard brick the phone. So far, we've only seen soft bricks AFAIK.

Boot to TWRP
Push Install (top left)

find the recovery.img and push it - TWRP will install it for you.
Then reboot into recovery.
You will now be in stock recovery and can use it to install update from SD card and install the B20 firmware from ZTE

Hah, no, your guides are not hard to follow. They're great
I think the bigger problem is that there are a lot of threads to wade through and there are various posts within in each thread that address specific issues users have run into. If someone who claims not to be "tech savvy" doesn't understand something in your thread (not because it's unclear but because they have zero experience with this and need some hand-holding) and then happens to read something else in the thread and tries that, it can get messy.

That is my problem entirely! I AM tech savvy as I have worked as a Microsoft/VMware Systems engineer for over 20 years and when I try to make heads or tails of doing some of the things necessary to flash a ROM, or root, or unlock the bootloader.... after my eyes glaze over I just stick with Nova Prime and hope the original manufacturers get everything worked out. What's really needed is a well written manual detailing step-by-step basics on what all these various things do as well as how to do them. Then more specific guides on a per phone basis. I know, it's asking too much! LOL :silly:

OK. Step by Step to get it back to B20
1) Move anything you want to save off your internal storage to your sd card or computer.
2) Download B20 image button.
3) Save file to SD card
4) Boot into Recovery by shutting it down and then push Volume Up Button+Power Button
5) When screen comes up boot into Recovery
6) in TWRP click Install, choose Select Storage, Choose Micro SDCard, Locate your update.zip file and click it
7) Swipe to confirm flash
WARNING: This will clean out your phone and turn it to B20. @DrakenFX can tell you how to not wipe the internal storage if you want to edit the update.zip file.
Hope this helps.
Thank you this is exactly what I was looking for. However, when I tried this the other day, it reset my phone as planned, but TWRP and bootloader were still on there. Any way of getting them off?

[Dirty-Santa Root] Bricked Verizon LG V20 Please Help!!!

I have rooted many phones before without an issue, and during the root process for this phone, everything was going great, I flashed SuperSU zip in TWRP and rebooted, since it was the first boot I expected a decently long wait, after about 25 minutes I followed the guide's instructions for Verizon since it did say some Verizon users were experiencing long first boot times. I took the battery out like it said, put it back in, then proceeded to fastboot boot2.img, like the guide said. After letting it sit for an hour this time, I got the idea that something was obviously wrong. After multiple attempts with no success I tried to fix it myself. So far I have learned that on the fastboot screen it says my bootloader is locked again, even after unlocking it. I have tried flashing TWRP as a recovery, just to at least have a recovery boot, that does not work either unfortunately. So as of right now, all I have is a v20 that has no OS, a locked bootloader, no way of booting recovery, I can fastboot with no ADB, and its virtually a paperweight. If anyone has a solution to at least get back to Stock, I would greatly appreciate it! Thanks!
First off. It will say: Bootloader Unlocked: No
Thats normal. 2nd. you are not bricked. You have TWRP installed. You just need to redo some steps.
PM me. and I will help you.

In his case we needed to redo from step 3.
I managed to un-brick mines after returning sadly from the Sprint store.
First, get to the boot loader screen and try running thru the steps again, especially step 3. You need to make sure you have TWRP.
Use this link to make sure you can get into the different modes (Download mode, fastboot, etc) http://www.hardreset.info/devices/lg/lg-v20/
Once you can get TWRP to show up,then you are good. In the mean time I downloaded "LS997-deODEXd-signed"
When I got into TWRP, I transferred the file to my phone. Rebooted from TWRP back into TWRP and flashed the ROM.
During my reboots, I do get a message saying my phone is corrupt, blah blahblah, but I just wait a few seconds and it will boot up.
Hope this helps.
I had managed to brick mines only 3 hours after upgrading from my Note 4. It took me from 9pm to almost 2am to get it back up again. I can live with the message about my phone being unbootable until someone comes up with a work thru.
Bricked T-Mobile v20
I have rooted many phones before without an issue, and during the root process for this phone, everything was going great, I flashed SuperSU zip in TWRP and rebooted, since it was flash a new rom on it then i get boot loop with TWRP. so i decide to OEM LOCK again after that everything was stuck on my phone just boot loop with LG so any solutions please help me...... THx u for help me.
Kinda nerve wrecking to read about all these "bricked" phones popping up after trying this method lol.. Perhaps I'll just wait until a more tried and true way comes out...
Dirty Santa root is not for the average user who has a couple of experience in rooting.
You have to at least have background on Hard bricking phones to fully understand what you are getting yourself into
For anyone that isnt on sprint that has "bricked" their phone. There are kdz's that will allow you to reflash back to 'stock". Someone had an issue with the kdz, but it was an easy fix. If you failed the process, it can be restored. Just if it doesnt want to boot, just lock and unlock the bootloader...
If your phone doesnt have a kdz, I know TeamDev is working on a custom kdz for such phones. Don't bug him if it isn't finished as I type this.
Anyone that can't get into TWRP, or has failed the process. Either start back at step 3, or if you have TWRP installed but can't get to it, the manual way to get into TWRP is a pain.
Keep your back cover off and hold the volume down button for ease. Now press the power button and as soon as you see an LG logo, let go and repress the power button. Its tricky.... If you get the corrupted screen, pop your battery out and put it back in quick and repress volume down and power. Usually if Im quick enough the first LG logo will hang a lot longer than usual and that gives me time to enter TWRP. A factory reset screen will pop up. Hit Yes twice.
Please help urgent

What does that mean? Not for the average user who has a couple of experiences in rooting.
I've only rooted 2 phones, this is my 3rd (maybe 4th). I am on Sprint. Instructions worked fine for me. I did have one hiccup, but it was my fault, and I was able to root just fine. I've been running for a few months now.
I have not flashed any custom ROM yet, I'm going to wait for the next major version of Android to come out. The only mods I've done so far are Titanium Backup install so I can remove Sprint crap.

it means dirty santa root got a high posibility rate of bricking a device compared to other root methods for other devices and if you have no experience in bricking phones before then you're screwed if it happens to you
Actually, if you follow the directions, almost none of the problems create a true brick-- which means unrecoverable. For most of the cases, you might get a soft brick, meaning you have to back out, use a KDZ to repair it or reflash something else, or start over from scratch and try again-- but usually (maybe with some help from here) you can pull the phone back into a usable state.
I would hazard to guess for the vast majority the process works fine, maybe with a hiccup, but I've not seen many reports of a truly unrecoverable brick from this method. It's complicated, yes, and you need to be ready to read a LOT to understand what's going on, but it seems pretty difficult to end up with a $700 paperweight with this.
So i have been trying tonroot my sprint lg v20 and everytime i try and go to the phone on mobile terminal to enter id
Then enter the apply patch /system/bin/atd /storage/emulated/0/dirtysanta i get this message and i cant go to step 2 to boot into recovery
Any help would be appreciated: i have a sprint v20 and i wanted to know if i have to flash the stock sprint rom or can i just flash lineage rom following this guide? I have it running on AT&T and i want to keep it on AT&T...
can you please assist
Could you help out, please? I don't believe I have hard bricked my LG V20 H910. However, I have read and tried all of the unbrick info out. It seems my screw up is unique. I completed dirty Santa then went to flash a custom. in the boot between that. I get a black screen and cant do anything even download mode will not come up. My PC does make its usual noises when i connect or disconnect, but my phone does nothing.
Ok, I managed to brick mine too. It's a VS995, it was running stock 1AC. I used the LGUP tool to downgrade it to VS99512A, and then did Dirty Sanata and TWRP. After booting into TWRP I decided to try lineage OS with Android 8.0, I did not make a backup of the Stock ROM, which was very stupid. Lineage OS 15.1 flashed but I had no cell service so I panicked and instead of wiping it in TWRP and using the backup of stock I should have created, I just opened LGUP and tried to downgrade it back to stock VSS99512A. Well LGUP said it worked, but when it went to boot it would hang at the Verizon logo with 4 pastel dots. Device manager could see an ADB device and I could connect to it with ADB. So I did and read the logcat. I could see it was trying to update as part of the rollback, but it appeared that some components from Android 8x could not be "upgraded" to Andoird 7.x. There was a repeated error about failing to update SQLite instance version from 3 to 1.
The one feature that could fix this is if the refurbish function worked with any of the VS995 KDZ files we all have access to. But alas, none work instead we only get the upgrade function... or so I thought. Somewhere in my search for the past 2 weeks I found a modified LGUP https://forum.xda-developers.com/v20/how-to/guide-patch-lgup-to-unlock-features-t3652222
**Please be warned what I did was absolutely ****ing stupid, and it was sheer luck I didn't screw anything up.**
From what I can tell if you only flash ("LGUP Upgrade") the KDZ from the same model it never clears the partition it just adds to it. My problem was there was stuff from lineage OS 15 stuck on one of the partitions that was making the rollback to stock fail because it kept saying it couldn't update the SQLLite DB from 3 to 1. So no "upgrade" within LGUP would work because the upgrade function does not clear internal storage. But the link above is to a version someone modded so you can force a partition update from any KDZ onto the system. So I started playing around with forcing KDZs from other models onto my VS995, and I noticed when using the Partion DL function with non-VS995 KDZ files it would say something about the partition changing. All I can assume is that the partition layout is so different on each model and it forces LGUP to re-partition the storage.
**Again I state for the record this was stupid, and I'm only fortunate it worked.**
I forced Partion DL of H91510d_00_VTR_CA_OP_1110.kdz, then H990N10b_00_OPEN_HK_DS_OP_1017.kdz, then back to VS99512A_06_1114_ARB00.kdz, then when it booted it gave the Verizon hello, and moved on finally but the setting service kept crashing while it was trying to load the Secure Boot screen. So I yanked the battery and went into the boot menu and did the Factory Reset function, and it worked.
Lesson learned, always make a backup and don't be so hasty to use tools that aren't fully functional (LGUP).
Perhaps what I've done may help others, maybe I've found out how to reimage or unbrick our V20s. Or maybe I just got really stupid lucky.
