[Q] Telus P935 Cyanogen recovery image?

I have rooted my Telus LG Optimus LTE (P935) successfully.
It is just the CyanogenMod 10.1 recovery image that isn't working for me.
I get the
Code:
---------------
Secure booting Error!
Cause : boot certification verify
-------------------------
------------------------------
Enter the fastboot...
Enter the fastboot...
Long time no see!
-------------------------------------------------
message when I boot to recovery.
Is there a simple fix for this i.e. use an different Cyanogen Mod, or my phone isn't really rooted at all and I think it is, or...?
The phone boots into the Telus ICS just fine, works ok and all, but if I want the thing to be upgradeable over time, I think I don't want to just rely on Telus to keep it up to date, do I?

You have to unbrick; final answer. No other way around it. Just pick one of the numerous guides here in the general section and follow it.

Unbrick? But it's not bricked...

Thanks for that, but I just want to confirm that even though I have superuser installed and working, and ClockWorkMod is installed and working, and when I boot the device normally it loads up into Ice Cream Sandwich just fine, and everything works great, I STILL have to follow a full "Unbrick" procedure just to get a "proper" recovery.img onto the device?
I'm not afraid of ADB / command line, but if you say "do the unbrick", well, OK, but could you recommend a SPECIFIC guide? The one I used to get where I am is this one:

Root Telus P935? post #13
So could you advise if I should retry that method or if I should try a different method, which one might be most likely to leave me with a LG Optimus LTE with a more-current version of Android than 4.0.4, AND leave the device with the ability to update to subsequent Android releases (either stock or Cyanogen?)
I am just trying to avoid a lot of fruitless trial and error if there's a known "best way" to do what I'm trying to do.

I haven't asked and I am only assuming that you are on an official version of ICS, right? If that is the case, it is fully possible to have root privs yet fail to flash a working recovery.
The thing is; if you are trying for a custom recovery, such as TWRP or CWM, then most assuredly you must unbrick. On the official ICS releases, having root privs means nothing as far as flashing a custom recovery is concerned.
Flashing a custom recovery+ROM will not hinder your ability to update either your custom ROM or upgrade to any (unlikely) future LG update.
As for which method is best, I personally say that ANY of them work as I have tried each one listed on this board and have encountered not one single problem. My personal recommendation is Hereric's guide, but in general, they all do just about the same thing. Other members do not share my "luck" as problems have been experienced with each method. The most important thing is to read through the guide a few times before starting it. One thing I will recommend is that since you have a P935, whichever method you choose, make sure you use a P93x .kdz instead of the Korean SU640 .kdz. I mean, it will work with either one, but there are a few minor gremlins that can pop up if you use the SU640 .kdz to unbrick.

Yes, the official Telus ICS. It was installed using the Windows LG upgrade tool.

Cyanogenmod 10.1 now stuck at boot screen
I have got Cyanogen 10.1 installed, now it's stuck on the cyan (I just got that!) boot logo (the circle with the hexagon screen with the moving spokes) and left it in that state far longer than should have been necessary for first boot... should I not have used 10.1?

Shouldn't matter which ROM you install. I'd wipe everything and try it again; or try a different ROM. You should be good to go once you've unbricked.

first boot with cm 10.1 will take about 10 minutes if i remember right, its probly not stuck on logo, just wait and let it install., if u leave it on logo for 30 min and its not booted redownload/flash it again.

Thanks; managed to get it installed

I had to flash / boot a few times... another tip is that in order for the "boot to recovery" to work, you first have to do a full wipe: once I realized that I was able to get various cyanogenmod firmwares onto the device and if I had problems, had to do a wipe then I could use the recovery firmware to try another.

[Q] (Help: Can't boot) Lollipop + eager urge for Xposed

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?!

Requesting assistance with baseband version, TWRP 2.8.7.0, and custom Roms....

After running a very very slightly modified stock room back from 10b (kitkat LG base image with bloatware removed), I finally had enough this past weekend and went looking for a new ROM for my LG G3 vs985.
I tried CM-12 initially, but as it was only nightlies and not a stable, I ended up with a few more problems than not, and they were noted so I moved on. After reading a few things, I decided to go with Resurrection Remix ROM. (I still want to.) After trying a few different times, I moved on to BlissPop, and got a similar-ish error, but it was simply a long overdue modem/radio flash. BlissPop installed fine. It's not exactly performing the greatest, though, so I went back to attempt installing Resurrection Remix.
When I try to flash it, however, I now get the following (somewhat confusing to me) error:
Code:
Comparing BASEBAND version MPSS.DI.2.0.1.c1.13-00053-M8974AAAAANPZM-1 to MPSS.DI.2.0.1.c1.13-00053-M8974AAAAANPZM-1_20140813_223054/b/modem_proc/core/securemsm/mba/src/mba_main.c
assert failed: g3.verifyh_baseband("MPSS.DI.2.0.1.c1.13-00053-M8974AAAAANPZM-1") == "1"
Now, mba_main.c is, at first glance, a compiler file (or code file, but that extension is what my classroom code has had since I started studying). So, I have no idea how to get it to the "right" baseband version.
I am not completely incompetent, thankfully, but I do have a couple of issues that may make it more difficult than I would normally imagine. Fastboot has not once worked with this phone. ADB works just fine, I can (and have) done everything from wipes to sideloads to install from zip files located on internal and external sd with no problems whatsoever. [Given what I have read, I'm going to assume the fastboot issue is related to Windows 8 and leave it at that; I could not get it to work in Linux either, however].
Any assistance would be greatly appreciated, and I hope everyone is having a good day.

Randomly, I resolved this. For anyone having a similar issue:
If you download the modem.zip for 23b and apply it via zip, it returns a lot more than just the baseband version when ROMS query it during the installation portion in TWRP.
The solution is to download the modem.img file from http://forum.xda-developers.com/verizon-lg-g3/general/reference-stock-img-files-t2966958 and then use the instructions in That post (the dd command lines for the modem block device in this case) from an adb shell as root for it to work.
Happy modding everyone

Flashing a New ROM, Get an Incompatible Baseband Version Error?

Warning: This post is long, and probably full of grammatical errors due to my writing it late at night. a TL;DR is included at the bottom, but to fully understand my problem, I encourage you to read the whole post.
Hello, xdadevelopers community. I really need your help. So, recently I learned how to install custom ROMs myself and the experience has been really informative but also very struggling. To make a rather long story short, I bought a used G3 from my friend, had him root it, put a custom ROM on it, and everything was working fine. Only, that ROM was on Android 5.1.1, which was contemporary to when it was flashed. I wanted 6.0.1, so I went about getting it. I eventually got that up and running with Resurrection Remix, but the battery life was completely awful. Idle is okay, but using the device results in completely intolerable battery life. I asked Reddit what to do, and someone recommend crDroid for it's great battery life. I attempted to install that, and that's where I got the problems discussed in this post.
Post where I got the ROM and GApps from
Specific ROM and GApps I got:
- crdroid-6.0.1-20160118-vs985
- So I go the one for Android 6.0.1, and the most recent one at that, last updated on the 18th of January, for my G3 model the vs985
- for GApps, I selected "ARM", "6.0", and "Stock" from the menu
Could another problem be that the ROM is 6.0.1, and the GApps are 6.0? If so, open GApps version exists of 6.0.1.
Basically, I downloaded the two zip files, the ROM and the GApps. I then formatted my device, wiped it, did a real quick, skip through everything set-up of my current ROM, enabled USB debugging, copied the two zip files (ROM and GApps, both of which were inside a folder I made called ROM) onto my devices internal storage (I don't have an SD Card), and rebooted into recovery. I'm using Team Win Recovery Project (TWRP) v2.8.6.1 if that's helpful at all. Once in recovery, again I wiped the device (using the default wipe function in TWRP, then doing an advanced wipe and specifically selecting cache and Dalvik Cache, just to make sure), and went to flash the ROM, finally. I navigated to the ROM folder it was located it, selected it, and swiped to flash the ROM. I got the following in response:
Installing '/sdcard/ROM/crdroid-6.0.1-20160118-vs985.zip'

So basically it failed to flash, apparently because of both an unsupported baseband version and a failure to execute a certain binary. Well, if you know how to fix the executing issue, that'd be great, although that's now what I'm focusing on here. I'm focusing on the baseband, because I believe that may be causing the failure to execute (although, as a newbie, I'm not sure if that's actually true). Apparently it was looking for version 35B, and that's not what I was running. When I set up my current ROM again just to be able to use the device, and checked for the baseband verion, it simply says "Unknown". Also, if you check out that link to the post above, it says:
We're mainly based on CyanogenMod so use custom kernels compatible with them!

. Well, I never installed a custom kernel, but I assume my friend did, because when looking at the kernel version on my phone it says:
3.4.0-CM-g74498f7

.
I'm assuming if it was a non-custom kernel it would just have multiple numbers separated by periods, not have all that info, and it specifically says "CM" in there, so I assume that should work, but am not for certain.
Anyway, back to the baseband. It was looking for a baseband version 35B, which I apparently don't have. I have a few questions about this
1. How are you supposed to know your baseband version if your settings app returns "Unknown"?
2. How are you supposed to know what baseband versions work and what baseband versions don't work on the ROM you plan on flashing prior to doing so? I saw nothing about this from from start to failure to install.
3. If the ROM I intend to flash doesn't support my baseband version, can I install a custom baseband version?
I will admit, I don't even know what a baseband is, and I'm too tired to look it up as I write this.
So that's it. I realize this post is incredibly long but feel like if it was shorter, potentially important information would be nixed. I have a TL;DR below for your convenience, but as I just said, to get all the important information, read everything above, please.
TL;DR:
Tried to install a new ROM
Failed
Failing apparently due to unsuppported baseband version
I can't determine my baseband version b/c my settings app returns "Unknown""
If baseband is unsupported, how do I know which are?
Also apparently "E:Error executing updater binary in zip '/sdcard/ROM/crdroid-6.0.1-20160118-vs985.zip' " is a thing. Caused by unsupported baseband version or entirely different problem all together?
Also maybe the ROM being 6.0.1 and the openGApps being 6.0 is a problem? If so, no openGApps 6.0.1 exist.
Please read the whole post to get all the detail needed.

NeatAndClean,
Thank you for providing the detailed information in this thread, so let's get to business.
First thing I want to straighten out is that you said your Baseband Version says "Unknown", i think you should check your IMEI information, if your IMEI is "null" then there is another problem to fix first.
If you have tried restoring from a backup after the "Baseband Unkown" issue and the Baseband Version still says "Unknown", then something happened whilst, or after you tried flashing CrDroid. At this moment I am not so knowledgeable about how to fix the Unkown Baseband issue, but it is a well known problem and usually coincides with the IMEI "null" issue. If you still are having that problem, I will try to find out how to fix it.
However, I will provide you with my full answer so this can hopefully get fixed at your preferred pace.
To start out, my questions are:
1. What ROM/Version of that ROM are you running right now? (I assume it is Resurrection Remix 6.0.1?)
2. Do you have a backup before trying to flash CrDroid? If so, I would suggest restoring from your backup to fix your "Settings Unkown" issue.
Once your Baseband "Unknown" problem is fixed, you can continue on to flash CrDroid (This time, it should work). Now I just downloaded the CrDroid zip file, that you used, on my PC. And just from opening it I can already tell that it is deeply based on CyanogenMod, but with some tweaks to make it CrDroid. Reason I mention this is because of this quote:
We're mainly based on CyanogenMod so use custom kernels compatible with them!

I'm not super knowledgeable on downloading Custom Kernels, but i do know that your Kernel:

is (I'm 99%sure) a CyanogenMod Custom Kernel, which comes when you flash a CM ROM.
Mine is:
3.4.0-CM-gc6520f1
[email protected] #1
Click to expand...
Click to collapse
and I'm running CyanogenMod 13, 6.0.1 on my vs985. Point is, you should be all set to flash CrDroid based on your Kernel.
Now, the "Unsupported Baseband" issue when flashing, at least CM based ROMs, is a known error recently. (In the past year I'd say) So the very common way to get around this, without having any issues, is to:
1. Go into your downloaded ROM zip, the zip you wish to flash, in your case it's crdroid-6.0.1-20160118-vs985.zip.
2. Extract the files into a folder (I'd recommend naming the folder the name of the .zip file, for ease in the end)
3. Open the extracted files folder
4. Open "META-INF" ==> "com" ==> "google" ==> "android"
5. Within that "android" folder, open "updater-script" file with Notepad, or a similar text editor.
6. Delete this line of code:
assert(getprop("ro.product.device") == "g3" || getprop("ro.build.product") == "g3" || getprop("ro.product.device") == "vs985" || getprop("ro.build.product") == "vs985" || abort("This package is for device: g3,vs985; this device is " + getprop("ro.product.device") + ".");
assert(g3.verify_baseband("35B:MPSS.DI.2.0.1.C1.13.4-00005") == "1");
Click to expand...
Click to collapse
7. You should be left with "ui_print("Target: lge/g3_vzw....." in your case.
8. Overwrite the edited "updater-script" back to it's directory (the android folder)
9. (Make sure you don't save it as a .txt file, it should still be a "File" (no extension))
10. Now go back to the "crdroid-6.0.1-20160118-vs985" folder after editing and saving "updater-script"
11. Select all the files/folders within, and add them to a .zip archive (Recommended by using WinRar)
12. You should end up with a .zip file visually identical to the original crdroid-6.0.1-20160118-vs985.zip, except this one has the edited "updater-script"
13. The edited one^ is the only one you need now, and is the one you will be flashing
14. Also, if you're curious I have done this many times with CyanogenMod, on vs985, and can assure you nothing bad will come of this... I assume the same is with CrDroid as it is deeply based on CM. (As long as you're "Unknown Baseband" problem has been fixed.
This procedure essentially gets rid of the Baseband/Model Check, ensuring a successful flash. Also as you can see in the code, it checks for the 35B:MPSS.DI.2.0.1.C1.13.4-00005 Baseband/Modem version, I believe "xdabbed" makes a flashable version of the 35B:MPSS.DI.2.0.1.C1.13.4-00005 Modem, which should eliminate the need to edit the updater-script. However, I strongly recommend to do the "updater-script" fix rather than trying to flash a different Baseband, as I have heard flashing a new Baseband can easily brick your phone, and you really do not need to do it.
I have Baseband: MPSS.DI.2.0.1.c1.13-00008, which does not match the "Baseband Check" and my ROM still works like a charm after the updater-script fix.
However, before you flash the edited crdroid-6.0.1-20160118-vs985.zip with your TWRP seperately, with the Marshmallow (6.x) ROMs right now, if you plan on using GApps you need to flash the ROM AND the GApps file at the same time in your custom recovery. Otherwise you will most likely get errors and you will need to re-flash the ROM and GApps.
Also maybe the ROM being 6.0.1 and the openGApps being 6.0 is a problem? If so, no openGApps 6.0.1 exist.

To answer this, no it is not a problem, you were correct.
1. The LG G3 is an ARM device
2. GApps only uses the first two digits in the OS version (i.e. 5.0.x or 6.0.x) (<==That "x" variable is the third digit in the OS version, and does not matter in GApps
3. All in all you have the correct version of GApps, no you just need to flash it at the same time as your edited ROM.
The procedure you did to flash the ROM was all good:
Basically, I downloaded the two zip files, the ROM and the GApps. I then formatted my device, wiped it, did a real quick, skip through everything set-up of my current ROM, enabled USB debugging, copied the two zip files (ROM and GApps, both of which were inside a folder I made called ROM) onto my devices internal storage (I don't have an SD Card), and rebooted into recovery. I'm using Team Win Recovery Project (TWRP) v2.8.6.1 if that's helpful at all.

This is great, again the reason it didn't work was because of the mismatch in the Baseband Check, which shouldn't persist after following the instructions in the "updater-script" fix.
Anyway, back to the baseband. It was looking for a baseband version 35B, which I apparently don't have. I have a few questions about this
1. How are you supposed to know your baseband version if your settings app returns "Unknown"?
2. How are you supposed to know what baseband versions work and what baseband versions don't work on the ROM you plan on flashing prior to doing so? I saw nothing about this from from start to failure to install.
3. If the ROM I intend to flash doesn't support my baseband version, can I install a custom baseband version?

1. The Baseband Version is not supposed to state "Unknown", as i said in the beginning, this is a problem that happens sometimes, I am not sure why, or exactly how to fix it, but if you do some research I'm sure you will find something, I will also do some research so I can try to help you with that if it is not fixed by a Factory Reset or a Restore from Backup
2. The Baseband Version that a specific ROM calls for will be in that "updater-script" I was talking about, at least that's how it is for CyanogenMod based ROMs. I think your stock Baseband Version will work with any custom ROM, as long as it is a ROM made for your specific phone. That being said, I do think that the latest Baseband Version for your specific phone does improve Network, Cellular and GPS Connectivity, but again I do not recommend venturing there yet, until you have alot of background on it and can do it safely.
3. If the ROM you intend to flash doesn't support your Baseband, chances are the ROM is not made for your phone or you somehow have a Custom Baseband that is not made for your phone. I say that because even though you get that Baseband error when flashing CM based ROM, it is still supported, it's just that you do not have the "latest" Baseband Version I believe.
I do believe I have answered all of your questions, at least I hope so. I'm sorry that some things I could not answer in great detail, but I tried my best so that you could continue on enjoying your device. I also have the VS985 so I'm familiar with the device.
Summary:
1. Before anything try to Restore from Backup to fix the Baseband "Unknown" issue, as fixing this is priority. If that does not work I will try to find a fix online, or you can try to beat me to it.
2. Once that is fixed^ you can carry on with the "updater-script" fix i included.
3. Then flash the edited ROM and your 6.0, ARM OpenGApps at the same time (one right after another, without a Reboot in between)
4. Then you should honestly be all set
5. Your Kernel is all set for CrDroid
6. The GApps you said you downloaded is all good for the CrDroid version you downloaded
7. You could also try to flash back to vs985 stock (10B) this will hopefully give you your Baseband back if you still need it after Restoring from Backup
7. You should get no errors now! Yay. Now you can enjoy a Battery Optimized beautiful Marshmallow ROM

Please let me know if you have any confusion, I would be happy to provide you with clarification, screenshots etc.

I've run into a huge issue. My phone is semi-bricked now, and I don't know what to do. I was getting the baseband version error as well, and I removed the lines in the script and then it failed stating "wrong footer". I tried first installing CM, then like a fool, I installed Cyanogen Recovery over TWRP. Cyanogen Recovery can't do anything. But the install failed. I no longer have any version of Android on my phone, I can't install that baseband package with Cyanogen Recovery. Stock ROMs all come back "wrong footer" as well. I can't install anything. I have Fastboot/ADB installed. Please help!
Edit: I'm not sure if Fastboot is actually working. I can't get it to do anything. It just hangs on whatever command I give it, and it continues to hang until I unplug USB, then fails.

First off, in my response to @NeatAndClean I said to have the Baseband error fixed before proceeding, which is probably what caused your error.
For your Fastboot issue;
1. Make sure you are using the original Slimport cable (over-suggested, I know, just making sure)
2. Try USB 2.0 ports if you got them, if not, give this a shot forum.xda-developers.com/showthread.php?t=2256359
3. Try updating the phone's drivers
4. Otherwise, reinstall fastboot/ADB drivers or SDK Tools
5. Alternatively try this forum.xda-developers.com/showthread.php?p=48915118#post48915118
Assuming you have a VS985, here are stock IMG files:
forum.xda-developers.com/verizon-lg-g3/general/reference-stock-img-files-t2966958
(If you do not have VS985 just find your Model's stock IMG files)
Here are commands you can use in fastboot once you manage to get it working, which will hopefully bypass your "Wrong Footer" issue. Obviously use your stock IMG files.
I would normally recommend flashing full stock TOT with LGFlashTool, but I'm not sure if it may worsen your Unknown Baseband issue (i.e. You may erase your IMEI if you Factory Reset when you have the Unknown Baseband problem) Here is everything you would need for the TOT Method: forum.xda-developers.com/showthread.php?t=2785089 - Also the old .dll needed for LGFlashTool probably won't work, so search LGUP_8974.dll and use that alongside the TOT instead) <== This should work if nothing else does, however, I don't think it will fix you "Unknown Baseband" but it may... I am not sure.
Finally, if you have ever made a previous backup, and still have it, if you restore from that your Baseband should re-appear and the error should fix itself. (I just figured you tried this already)
I once got the Unknown Baseband and IMEI - null issue, you could try to flash the stock Modem.img file for your phone, and try an IMEI injector program using the IMEI number in the battery compartment (Under the physical battery) But to fix mine I ended up calling the Customer Service and they eventually pushed an update file to my phone. I assume it was a Modem update of some sort, but it was a long time ago so I honestly don't remember.
I wish you good luck, as I know how frustrating these situations are. And keep in mind, I am only trying to help.
Please, to anyone experiencing the "Unknown Baseband Version" issue, focus on that before anything else, as you will most likely worsen your problem the more you do with the issue persisting.

Up until this point, I've only had the phone stock with the OTA updates from Verizon. It was updated the day I got the phone, so the baseband must be official, even if not supported by CyanogenMod. I wanna say it's 23B. I tried everything to get fastboot to work. I'm using the original cable that came with the phone "LG Electronics DC1501" plugged directly into a USB 2.0 port on my motherboard. If fastboot doesn't work, I can't flash imgs. An OS doesn't exist. I don't have a versatile recovery (Cyanogen Recovery might as well be stock). You say there's a chance TOT method will erase my IMEI, but you say there is an IMEI injector that can restore it, correct?
At this point, I'm at a loss. I really don't know what else can be done. I'm going to give the TOT method a shot. The website you linked has been suspended, so I'm following the 2015 updated method here: http://forum.xda-developers.com/showthread.php?t=2432476

OMG! It worked! My phone's still activated, so no problems with IMEI. I may be coming on kinda strong, but I LOVE YOU! I spent several hours yesterday, and I've been stressing about it ever since. I even put in a repair request with LG...now I can cancel that request. Thank you thank you thank you!

@Knux Kitsune Haha I'm glad that you finally got it working, I apologize about the problem with the link... I think I messed up all of the links in my response I'll fix those for the future. But again I'm just glad you got it working with no more problems, thanks for being so patient, XDA is like the best forum out there IMO.
Also, just curious, if you don't mind responding.. I was just wondering, did you use the KDZ method from the link you posted? Just want to know so that I know how many solutions there are for problems like these.
Anyway, enjoy your "new" phone lol, and be careful in the future because I know how painful these situations can be!
Glad you got it fixed!

I actually downloaded the KDZ, but I used the TOT method. I actually almost did it again, because in KitKat, my connection was very unstable, I did install the 35B baseband from XDABBEB, but that didn't fix the problem. I tried updating the firmware legitimately via LG Upgrade Assistant Utility (Verizon), but it kept giving an error everytime it got to 20%. I found no support online to get past this error, so I looked into stock ROMs and found XDABBEB (again) had built a flashable stock ROM for my phone, identical to what Verizon released last month, but with root access. I flashed TWRP 3.0 with Flashify, then flashed the ROM. The first time I flashed it, the phone showed that the phone service had stopped responding, a dialog box that only comes up once per cycle...super annoying. I managed to get back into Flashify and attempted installing the ROM again. I was actually prepared to do another TOT flash if it still had issues, but the second time wiping and flashing worked. My connection is solid, and I've had no errors (so far). It seems to run faster on Marshmallow than it did on Lollipop. It's pretty much the end result I was going for when I tried upgrading some 35 hours ago.
Update: Apparently, my baseband is fixed now. It did say Unknown before, even after flashing the 35B baseband from XDABBEB (initially anyways, reflashed after wipe just before flashing the ROM), but now it says "VS985-MPSS.DI.2.0.1.c1.13.4-00005-M8974AAAAANPZM-1"....so that's...good?

Awesome, well that's good that you eventually reached your goal. I can't say for sure why your connection was unstable on the Stock Kit Kat, but the 35B baseband is for 35B (5.1.1) Lollipop. The TOT method flashes back Stock Firmware, which is 10B (I believe 4.2.2) - KitKat so you would then need the Stock Modem IMG: (10B Modem File) but you are past that.. which is great. The Phone Service not responding is, I'm sure, a result of the incompatible 35B Modem mixing with 10B (4.2.2) Software Version. That's why flashing XDABBEB's Stock ROM fixed it (at least the second time around), because it includes all the stock IMGs, including the stock Baseband Version (10B).
But I'm so glad that you re-flashed and wiped again, because you have literally managed to return it to complete stock. Your baseband is official, and seems to me.. completely fixed!
Just confused with this:
It seems to run faster on Marshmallow than it did on Lollipop.

Are you running Marshmallow now? Or Kit Kat? I think I just lost you at some point haha.
But congrats on fully flipping your situation around! And in fact, because you fixed your Baseband issue, this thread is now completely answered! :good:
The TOT Method does wonders, doesn't it :victory:

Sorry, the stock ROM I used is http://forum.xda-developers.com/ver...t/vs985-46a-stock-flashable-firmware-t3304365
It's identical to what Verizon sent out last month except it is rooted, which I don't know why phone providers are so against letting their customers have full access to phones they either own or are leasing. I own this phone. It's paid in full. I want root access... Anyways, yes, it's Marshmallow.

Ohhh, I see. I totally agree with you, it really makes no sense... the phone was built a certain way, it was meant to be used like that. Why the providers "nerf" them, I don't know. Even with the FM radio, they disable the receiver on the phones, I assume so that we are forced to stream instead, and they make more money. It's absolute sh**. But yeah, alright well that's cool, I might have to flash that myself actually, Marshmallow is lookin' really nice, as long as the battery life ain't too bad I'm gonna test it out myself!

Excuse me, first i´m sorry for my bad english language. I have same problem the unsupported baseband, but till now i just feel confused. I flash the Resurrection Remix Nougat on twrp and says unsupported baseband error. What should i do first? Flash the new baseband? If it yes, which baseband version is suitable for my device. Im using LG d855 and running android 6. Or i must unlock bootloader before flashing the new ROM? Thankyou, hope anyone will answer my stupid question.

I am using micromax q372 smartphone, had an android 5.0 stock ROM, and now i have installed resurrection remix 5.5.9, and my DEVICE OFFICIALY DOESN'T SUPPORT, and I garbed all of my luck and installed it, and now I have a fully working custom ROM on a unsupported device, the only problem I had was with the data connection, and I sorted it out, now everything is working, .............now I want to install resurrection remix 5.9.X , and my device doesn't is not on the support list, so ....can I do it , without any bugs? .......plz advice me

Question Bricked for Days and usable WiFi is $$$ for vanlife, help!

I was ALL good with my Pixel 6 pro, rooted and hours of tweaks in. My idiotic mistake here was I did not make a flashable backup before flashing the magisk-rooted despair kernel. Instead, because of laziness to find a nandroid backup method, I made a half-assed backup by dragging and dropping on my pc, and this has cost me.
Immediately after flashing via the 99 cent kernel flash app (can't remember the name) I was getting caught in the G loading screen bootloop.
Since then, I've tried everything. Every combination of every fastboot command I have found, on Windows and Ubuntu, multiple cables, etc. This has worked for me in every version of Android since 4.0 or earlier, as I've gone this whole time without really gaining understanding of any of the back end.
Now I cannot enter fastbootd. I get errors in fastboot that the "/system" partition does not exist. I have no stock recovery and can only enter Fastboot bootloader mode. GrapheneOS will not install due to an error at the final step indicating that fastboot is too old, despite the updates I keep reinstalling (Graphene web installer failing on download portion). Stock Recovery Flash Tool never works for me, always an error on the download. When manually flashing Stock, I am hit with the missing system partition error, the error that the image is too large for the partition, cannot determine image filename, etc.
Now, fastboot reboot bootloader doesn't even work until i unplug and replug the phone back in. And no flashing commands are attempted until the phone is unplugged/replugged. My bootloader is still unlocked as confirmed by the fastboot oem unlock command response.
Essentially I believe I am in need of a complete wipe, beyond anything I've done yet. I think I need to create new partitions before flashing? Someone please help me I'm dead in the water and on motel wifi to try and fix this stubborn beast.

When I first got my pixel 6 pro, I didn't let the update fully install and ended up using the web flasher to get it working again. Have you tried that? It'll be a full wipe but at least you would have your device.

Oh I've wiped it along the way already, since the "incident" of the kernel flash. Multiple ways. I would love to use the web flasher, but it just doesn't work for me. The download never completes, and I suspect even if it did that at this point it would get stuck right away and throw me an error message, likely deleting the whole download along with it.

Not sure when you said you used "Stock Recovery Flash Tool" if you meant the "Android Flash Tool". But just in case you didn't, that can force flash partitions with it. Probably your best shot.
Android Flash Tool
flash.android.com

Android Flashing Tool online unbricked me the other day. You have to be patient with the tool as it took me several tries. It will totally wipe your phone, but at this point you just need to rescue your device. Keep us posted.

thanks for the tip. i'm trying the android flash tool again now. and will keep trying it until it at least passes the download stage. and yes i tried all the manual flashing guides out there...and hybrid combos of all as well. i mean i'm positive its my fault for missing SOMEthing somewhere but many hours have been spent with overall negative progress.
my track record is still zero hard bricked devices or soft ones I couldn't fix over all these years so i'm not too worried but i could use my phone back haha
will keep posted as requested. ty again.

I know this doesn't help your immediate situation, but when flashing anything like custom kernels, I would advise not to use some random app to flash it with, just follow the directions in the OP of the kernel's thread, and make sure you have up to date Platform Tools and driver. CleanSlate and many or all the custom kernels also require flashing more than just the boot.img.
Good luck, I hope you get it back working for you.

Hey guys, the Android Flashing Tool finally worked for me and I am up and running again. Thanks for your help and tips. Hacking phones is more important every year and thus I truly value your skills and advice. This community must survive the new world order. much love folks
