LS997{Sprint}TWRP stock backup boot,system and data images needed

Does someone has them please PM me I will give you credit$ because I'm in dead end with unusable anymore ls997 device.
I have lost my backup (pre-santa pre-rooting pre-custom roms) it was on my sd card which I formated after a while not thinking.
later I did other mistakes: on my dirty santa rooted ls997 I flashed LS997-deODEXd-signed. All fine but than because in software info it said US996 (yes because of the bootloader) I went for stock us996 10f .kdz using uppercut which didn't stop me because it recognised the device as us996. us996 .kdz rom removed root and twrp, all was fine except I got no service (all type of networks). phone recognises the sim card, but that's that no more (even manual setting the apns and manual choosing the network(can't be retrieved) even 112 and 911 won't work. Than I went re-rooted and re-flashed LS997-deODEXd-signed again, but my service was gone there as well (previously okey). tried other ls997 custom roms, in all of them service was gone. I guess I can fix that with twrp recovory of original stock backup files (mine I deleted by acc). I will give credits to anyone helps me.

You probably need to flash the radio from Sprint using dd
Go here for modem https://forum.xda-developers.com/showthread.php?t=3548454
dd if=/storage/emulated/0/modem.img of=/dev/block/bootdevice/by-name/modem
When the modem file is on root of internal storage

I will try it today and report back thank you fellow.

I flashed (wrong) modem.img via twrp->install successfully. Big mistake as I ended up stuck in (attached photo) green screen after lg logo. Twrp still works, also adb still works when I hit volume down + plug the type-c cable in. Tried fastboot erase system than fastboot flash recovory twrp.img than from twrp flashed 1)twrp flashed other custom rom-no success(green screen still there after flash->reboot->lg logo) 2)flashed twrp backup I created the other day (only boot & system were ticked when I created the backup, they are from working status with custom LS997-deODEXd-signed as it is the same rom on my 2nd working v20) - 2) also went not successfull
3) opened uppercut on my pc but it recognises my device's port but version is uknown therefor can't use uppercut(it won't start because unkown version, pre-issues it worked, also on my 2nd v20 works but I suppose rom must be ok and booted in order uppercut to starts and gets the version of device).
4) I'm stuck. Can I somehow use my 2nd v20 (rooted, twrp ok, custom romed LS997-deODEXd-signed (old one from december),all software and hardware works perfect(including radio I do have signal bars data etc.) to fix my green screen on 1st v20 so if I fix it I can proceed with your instructions for the sprint radio via dd

If you did flash radio then i would try to flash the radio but i have never seen the green screen

If your device has a kdz, you can extract everything from it and flash accordingly. Or I think there is a fix for the unknown thing. My device does it as well.. There are dll files you need to get it to work.

He dosnt have a sprint kdz. Im asusimg hes talking the us996 kdz. Why you would have hit the sprint ls997 with the us996 kdz is unknown to me.. The sprint kdz is not avalible and the version that was leaked isnt in circulation and is encrypted.

Im assuming you'll need more then just system and boot.img
The kdz i assume replaced your custom aboot. And the radio and modems all got swapped with us996 the unlocked version i hope and not tmobile variant.
I have full backups but parts contain things like ur esn imei and cant be shared.. Need more info on what is what. The green sceen is a big issue. Thats aboot crash

Maybe you lost the phone's EFS/IMEI file folder, Did you check that?

yes I used us996 .kdz. Im willing to do it again in order to undo the green screen and unbrick my phone.
your words seems legit yes I assume the us996 replacaed radio and modems that's why I got no service. BUT all else was working, no green screen. AFter that I flashed h918 modem.img using twrp->install->choosed modem.img->swipe to install. Only than I got stuck with the green screen and no re-flash helped. Tried twrp restore with 5gb backup fom us995 nrd90m stockimage (system,boot,chace) with no result - again green screen after lg logo.
If I can get uppercut/lgup reading my phone version again (with dd command and changing dll) I will swap back us996 kdz which was fine (than re-root re-flash twrp and custom rom - all back to square 1). us996 kdz is fine it did not make the green screen, booting h918 modem.img after that through twrp did it. us996 kdz only swapped my radio and modem therefor got no service but that's it no more harm.
I was in the US only temporary, now Im in europe using my tmobile(usa) on roaming(not for long I don't need my us number anymore) and european sim card on my 2nd v20. Therefor I don't really care anymore for my ESNs

Well, i think you have to check on Settings> About phone> Status and here it shows the phone's imei number, if you only see "000000000000000" then your phone does not have the EFS folder, then you have to fix that....

I checked, it's fine, imei is ok - the actual and full one
Update: I'm considering buying another clean ls997 sprint v20 since mine are both rooted etc. My Q is how can I extract the .kdz from the new clean sprint v20 unit ? (As I noted even with full twrp backup images the green screen is not fixed it's deeper issue maybe .kdz will fix it hopefully). I don't mind sharing the sprint .kdz afterwards since I will not use the phone in the US anymore anyways.

The kdz has to be leaked from Sprint....The only one that got leaked wss encrypted and we can't use it...the only way to get it flashed to stock is at a Sprint store unfortunately...it sucks

Lol... As you learned, cross flashing radios is a great way to brick. Also, never flash a radio through DD unless you are 10000% sure you know what every part of what you are doing does, and how it works.
Here is your problem. Your baseband (radio) partition is supposed to be a certain size... However, upon flashing a wrong image, with a low-level tool (DD), the partition is now corrupt and/or mis-sized. That means that another partition is overlapped by radio, or a part of radio is overlapped by another partition.
If you somehow get a KDZ to flash, it may or may not fix it.
The only way to fix this, would be with a very low-level tool, to manually repartition everything in pristine condition. If KDZ does that, then great. If not, then there is really not much you can do.

I'm trying my best to get the KDZ to flash, but it won't let me. Download mode on thehpne successfull, from there on - not.
Please recommend me some workshop where they can fix this green screen and get me going. It's sprint bad esn lg v20 should I contact Sprint and tell them I rooted and soft bricked and can they get me back to stock and charge me for this service that's fine ofcourse ? I can ship it asap since now it's just 350$ piece of shiny plastic in a box.

i get the impression that you didnt actually read the OP's post.
he has a kernel panic, and is unable to get his phone to boot android. the green screen in the very first post indicates as such.
in a small nutshell, OP flashed a file to a place that it should not have been flashed to. most likely, OP has given him/her self a really expensive doorstop.
unfortunate, but a lesson can be learned here. expensive and avoidable, unfortunately.

Lg V20 unlock bootloader problem

I have bought this secondhand handset, he says that it's us996 series, and when i check it in the setting information, it says us996 series, but then i decided to unlock bootloader, we know that us996 series could be unlocked legally, so when i follow the instruction, including put my IMEI and device ID in LG developer website to get permissions, the website says that my handset is LS997, so it can't unlocked legally, could any of you solve this problem? I desperately need your help, thank you (english is not my native language, so sorry for the language)

Sounds like LS997 that was rooted before dirtysanta was patched, and they probably flashed a 996 rom, check ☒ see if you have root. If so it should be unlocked

I've tested it with root checker and it says no, then i checked the bootloader status whether it's unlocked or locked, and it says still locked, it's like no sign that this device had been rooted before

check the sticker under the battery for model number, what does it say? if it is not US996 you can't use LG Dev site to unlock.

WitchKiller said:
Yes it is, does anybody have a solution?
Click to expand...

The problem is you got sold a ls997 that got flashed with us996 firmware including the bootloader while it was still possible. The solution is to use it as is, return it, or root it with the dirty Santa method and make sure you use a kernel with the dirty Santa fix (since most kernels/roms labeled just us996 won't have it)

You need to roll back to version 10f, grab LG up from this thread, put it in
C:\Program Files (x86)\LG Electronics\LGUP\
Grab the firmware
Put your phone into download mode (power off / hold vol. up / plug in USB cable).
And then use the upgrade option in LG up to downgrade. Then follow the dirty Santa instructions

Probably intentionally removed, its literally impossible to miss. It takes up a large part of the back of the battery compartment (here's my factory unlocked us996 sticker on the original screen assembly). The clean back area is of course the battery compartment. The model being listed as LG-US996 (instead of US996) and the USA on the side (as opposed to BPT or UCL) differentiate the factory unlocked from the other two us996 variants

That's just it: there's no ls997 firmware but it can flash other variant's firmware (except the T-Mobile h918) as long as it hadn't gone past a certain ls997 update (others reading this thread in the future, don't try it, if it's been on Sprint firmware and been updated in the past century it's impossible, think the last Sprint update that could was ZV6 or ZV7 iirc).
Since it's on US996 firmware it should be fine. Also a good idea to use the dump option in LG UP to backup the modem, modemst1 and modemst2, and misc before you reflash with LG UP, basically everything but user data won't hurt.

that was basically all there is to it.
Get LG UP (put it in C:\Program Files (x86)\LG Electronics\LGUP) the firmware (kdz)
Put your phone in download mode by powering off, holding volume up and then connecting to the PC. Open LG UP.
Hit dump option, hit select all, uncheck user data on the partition list, then click ok. Since the phone was originally the LS997 the modem may be wierd so having a known good modem and modemst1 and modemst2 backup (done by that dump) is a good idea.
After the dump actually rollback by selecting the upgrade button and adding the kdz to the bottom section.

Flash a kdz with patch level of december 2016 using same above method. After that root using your preferred rooting method (Mine is given in signature, need to see in desktop mode). Then flash either SuperV20 or Vincent ROM and you should be fine (Let's hope so). I personally like Vincent more because it is based upon UX 6.0, looks nice and have most things ironed out.

Lg v35 download mode fix?

Was trying to flash fi firmware to an att lg v35 to try and bypass a FRP lock and it failed. Now i am stuck in download mode when i turn the phone on and can not get anywhere else. Anyone got a possible fix? Im out of ideas since i cant just flash a stock firmware.

i was almost tring to do the same job on my att v35 locked... I don't know how to help you but your attempt stop me to proceed with it.
or you may try to flash a different kdz? Or I knew about the lg bridge... does it have a recovery option?...it should.

Or you can try with
LG MOBILE SUPPORT TOOL
look for it on google :good:

Tried two different kdz files. They all fail at 11% on lgup and get you brinked into download mode. So lg bridge is impossible. I will look into lg mobile support tool, have not tried that yet.

Did you use uppercut? Similar thing happened to my LG G5 and I realized you have to use Uppercut to do that sort of thing.

It may or may not work, it works with the G6 and V20, I’m not sure about V35. But it said it might.
I hoped this works for ya! Check your PM, too.

I had the same issue. Unfortunately I just sent mine in to LG for them to hopefully repair. I tried so many different things to get it going with no luck.
Not much help but that's what I did

Hi just saw your post and I have an AT&T V35 too so this should help:
1. Uninstall any prior version of LGUP currently installed.
2.Head to Post #18 at https://forum.xda-developers.com/android/general/lg-v35-amazon-project-fi-t3819470/page2
3. Download the ' V35_lgup_modded.zip' ; Unzip & install, then ensure the .dll file is also copied to the COMMON folder (C:\Program Files (x86)\LG Electronics\LGUP\model\common)
-If there's no COMMON folder, create one.
4.Shut down the phone completely(phone should also be unplugged), then get into download mode (With phone off,hold down the UP Volume button and connect the phone to your PC while still holding down the UP button) and release the UP button once you see 'Download Mode' on the display.
5.Now, there's no V35 AT&T Kdz file available online so the next best option is to use the Google-Fi kdz you tried earlier; So launch LGUP & select the Kdz file .
6. Next choose the UPGRADE option and flash.
7. Hopefully, that should bring your phone back to life and if not, try again with the REFURBISH option(will wipe user data etc.)
8.Lastly and very important, though you may be tempted to mess around with additional LGUP options such as PARTITION DL etc.; Remember the V35 is still relatively new & has low support so be careful - So far, cross-flashing seems to be fine except for Korean Kdz files but flashing partitions WILL currently cause you to lose either your IMEI/Serial Number or Both.
Cheers

Thanks. The guide works good to flash the fi .kdz but unluckly it doesn't unlock the at&t phone (as expected). I made the try. So people if you have an unlocked v35 branded you can go straight with this guide to unbrand it :good:
If someone can help to find a way to sim unlock v35 please give an help. Thanks :highfive:

Just want to be clear on one point. I have an unlocked att version (v350awm) of the phone and have followed steps listed above. i was about to upgrade to the fi kdz but noticed i have two options on the modded LGUP to upgrade, "Fota upgrade" and "Fac upgrade". I was thinking that it should be the Fota upgrade option.?

Hi, just stick to the 2 options at the top left - REFURBISH (For a total wipe, including User Data) or UPGRADE (To update without wiping User Data)

Wanted to thank you to for the info. Am now using the Google Fi rom on my v350awm without a problem. And the beauty of it is, no bloatware.
Again thanks

Google Fi Rom/Kdz
As I posted previously, I successfully restored V350ULM10f_00_NAO_US_OP_0913.kdz to my carrier unlocked V350AWM (AT&T model) using the modded LGUP. Now my thought was that this was the Google Fi rom that comes on the Google version of LG V35. and I know for fact that this rom doesn't have any of the AT&T bloatware that comes on the AT&T LG V35.. When booting I no longer see the AT&T logo, just the LG logo. But the interesting thing is when I check the software version it shows V350AWM10f which seems to say that I really still have the AT&T ROM but the AT&T Bloatware and logo have been stripped out.
Thoughts?

I just got a chance to try this today and it worked awesome. Thank you! Now I have no bloatware on the phone, and managed to get past a Frp bypass. Now I just need at&t to unlock the device and I will be good to go!

True, after flashing, the software version under 'Settings' does not change to reflect the Google Fi update. This is simply a minor labelling error for now but the important thing is that the update is successful as evidenced by the lack of Carrier bloatware/logo. You can actually verify the fact that you are no longer running an AT&T ROM by trying to update via LG Bridge & it should say there's no available AT&T update.

You are welcome, glad I could help & major thanks to
"metal409" for sharing the modded LGUP in the first place.

I;m gonna have to agree with you as I just installed the latest (just out) version of the Fi Rom, V350ulm10h which can be found here: lg-firmwares.com/downloads-file/17590/V350ULM10h_00_NAO_US_OP_1130.kdz
After installing, my software version is now showing V350awm10h, again indicating that I still have the AT&T Rom.

Hi Yall,
I'm in this same predicament. I've already disabled most of the AT&T Bloatware .... but I'm still super annoyed at the lack of updates (ATT will only let you get OTA updates if you are on their network, my phone is currently unlocked with an unlocked code and on the T-mobile network)
Are there any other benefits to flashing to the Google Fi version other than debloating? Any chance of VOLTE working? or band 71?
Will the annoying carrier branding on the top of the status bar disappear?

Soft brick

I soft bricked the phone and now can only get into download mode. The phone only has two partitions and I was hoping that flashing a KDZ would fix this.
I'm running Linux Mint on my machine and using SALT an LG type open source program in order to flash.
Question: I heard that I should flash something before the Dec 2017 security patch. I can't find any KDZ files unfortunately and was hoping someone here would have a server I could pull it from.

Oh goodness I'm so terribly sorry I seem to have over looked it.
It's an LGV20 H910
What happened is that I used a ROM that was for another model and it kept crashing. After some time I started tinkering with some other software before I realized that even though I bought the device as a 996 I got the 910 version from the eBay seller.
In any case I remember someone mentioning that if I'm going to flash a stock kernel I should stick to something that was before the DEC 2017 security patch so that I can keep the exploit that enables ROM flashing.
Not sure if that's referring to the bootloader that I'll have to flash or the stock ROM itself.

Oh and lastly I remember someone mentioning that the KDZ for my variant of V20 doesn't have any stock images so I'll have to take one from another model flash it to boot then root it and flash a custom bootloader and then re-flash a custom ROM.
That's probably not how it's suppose to work but it's roughly what I remember.

dear what is the condition of your mobile now? does lg up detect the mobile? if so than use LG UP patched version and try to flash your stock kdz.

Sorry darling that it took so long to reply!
My phone is detected by SALT (the open source program developed by steadfasterX) BUT it is doesn't want to work with LGup on a windows system because I don't have the proper .dll to work with my model type.
The LGup log file says
"LGUP can't load the model."
funny enough though the log file shows the model type right after a hex key string.
It says "LG-US996.. US99610d..."
I can get the phone into download mode but the phone doesn't have any partitions right now. So for now it's a paper weight.

every kdz has dll file, even lg up has dll file. you can extract kdz and get dll for your specific model.
use lg up patched version, search on xda, it will solve your problem.
i can not help on linux and SALT, as i dont have these. if you have access to windows machine, than i can try to sort problem for you.

LG UP regognizes the wrong device

When I launch LG UP, it recognizes US996, but I have an H990DS. What can I do to change this?

Did you flash it previously with US996? Or did you buy it second hand?
If there is no issue then there is no problem.
If you use LGUP Patched you can use Partition Download option to flash DS KDZ and if it still says US996 flash it again using upgrade or refurbish.

No, I didn't Flash US996 previously. Not second hand. I uswd LGUP in the paßt and it was alright.
THis I don't understand:

LGUP recognizes the "wrong" device
, when I use a H990DS kdz and it stopped working.

I don't see what the problem is. What difference does it make to you what LGUP recognizes the device as. Just ignore it.

When I ignore it, LGUP stops the uploading process to the phone.
For a few minutes I found out, that the serial number of my LG V20 h990ds begins with LGUS996. I think, this is the reason. Shall I change this number?

The serial number should have noting to do with what you can flash on your phone. I really don't understand what your issue is, or what's causing it.
