[HOW-TO][LS-980] Restore, Downgrade, Install CyanogenMod on LG G2

READ ME FIRST I am more than willing to help you guys, so if you have questions, please ask me via my facebook page, as I get notifications there instantly. http://facebook.com/vacationlandtech
Also of note, I no longer have a LG G2, and it has been a long time since I made this, if you can be as descriptive as possible when asking questions, that would help a lot. Also, because it has been quite a while since I've been in the G2 community, I'm not up to speed on anything newer than early November, 2014. I don't have experience with ZVE+, CM12+, CloudyG3, etc. so if you have problems with new ROMs and software, get help from the people who make/support those ROMs and software.
Good luck!!
So I've been helping around the forums with people trying to install CyanogenMod on the Sprint LG G2 (LS-980). I have done this successfully and will outline my steps to do so below. A small caveat – I've only gotten this to work the way I'll outline below. I've tried getting CyanogenMod after the LS980ZVA/C/D OTA and no matter what I do I cannot get it to work. That being said, let's get to it.
Edit: I've added videos!!

*REMEMBER* - Always create Nandroid backups before flashing a ROM or doing anything, really.
Required Materials (some of these files (LS980ZV8_13.TOT) are over 2GB, FYI):
EDIT: I have put all the required files into a .ZIP archive and uploaded it to Mega
There has been a report that that the CyanogenMod .zip in my file is corrupt. You can still download the file I uploaded, just get CyanogenMod from the link below.
Update: I uploaded *just* the LS980ZV8_13.TOT file to Mega. Here is the link (beware it's not zipped, it's over 3GB).
Code:
* LS980ZV8_13.TOT - [URL]http://storagecow.eu/Xda/LG%20G2/Stock/Sprint/LS980ZV8_13.zip[/URL]

* LG G2 (Verizon) USB Driver - [URL]http://tool.xcdn.gdms.lge.com/dn/downloader.dev?fileKey=UW00520120427[/URL]
* GApps - [url]https://s.basketbuild.com/gapps[/url]
Now, back up any files you want to keep from your phone. This process will remove EVERYTHING from your phone INCLUDING Internal Storage! Also install the USB Driver.
Let's get to it (please read all instructions before doing anything):
Resetting to Stock
Required files: LG Flash Tool, MegaLock.DLL, LS980ZV8_13.TOT, USB Drivers.
1. Install LG Flash Tool , but don't launch it yet!
2. Copy MegaLock.DLL to the root of the installation directory of LG Flash Tool.
3. Launch LG Flash Tool.
4. Check “Manual Mode”
5. Browse to the .DLL file you downloaded by clicking the “...” button to the right of the first text box.
6. Browse to the .TOT file (it'll have to be unzipped) by doing the same thing for the 2nd box.
7. Click okay, then click the green arrow at the top right of the window.
8. Wait for one of the boxes to turn green and say “Ready”
9. Turn off your phone.
10. Plug in the phone to your computer while holding the Vol+ key to put your phone in download mode.
11. Open Device Manager on your computer by pressing Win+R and typing “devmgmt.msc” without the quotes, then pressing enter.
12. Scroll down to “Ports” and expand it.
13. There will be an Android entry, right click it and select “Properties”
14. Select the Port Settings tab, and select Advanced.
15. Change the port number to 41.
16. You may have to unplug and reconnect your phone.
17. The box that said ready should now have some messages inside it (ie. “Waiting for connection.” and stuff about phone checks).
18. Allow the flash tool to do its job, after anywhere between 10 minutes and half an hour the phone will be done resetting. In my experience, the flash tool will always say there was an error after the phone reboots, this is because the phone reboots into Android, but the flash tool has done everything it needs, don't worry!
19. You can now unplug your phone and close LG Flash Tool.
20. Your phone is now on stock LG firmware LS980ZV8!
** - If you're going on to flash CyanogenMod, get through the initial set up, let the phone activate, but don't worry about getting apps or settings, they'll be gone after we flash CM.
Rooting
Required files: IOroot25, USB Drivers
** - I'm going to write this as if you've just reset to stock firmware.
1. Navigate to Settings > About Phone > Software Information
2. Tap on Build Number 7 times, or until there is a pop-up stating that “You are now a developer!”
3. Go back to Settings
4. Go into Developer Settings
5. Enable USB Debugging
6. Plug your phone into your computer.
** - If there is a RSA Fingerprint pop-up, accept it and check Remember this fingerprint
7. Navigate to Ioroot (you may have to extract/unzip the files) and execute root.BAT
8. Follow the on-screen instructions.
** - Note that Ioroot automatically backs up your EFS partition, make sure to keep these files in a safe location, as they can come in handy if something goes wrong.
9. After Ioroot is finished, you can close the program, unplug your phone and disable USB debugging.
10. You're now rooted, you may verify by downloading a Root Checker app from the Google Play Store.
Installing a Custom Recovery
Required Files: None
1. On your phone, navigate to the Google Play Store.
2. Search for FreeGee and install it.
3. Open FreeGee and allow it to download the device list.
4. After the download is finished, you will see a changelog list, close this.
5. Tap on install TWRP (or CWM if you're more comfortable with ClockWork Mod).
** - I recommend TeamWin Recovery Project for newer users because it is more end-user friendly, touch-capable, etc.
6. Wait for FreeGee to do its thing, then you have a custom recovery installed.
7. If you want to, let FreeGee reboot you into Recovery in order to verify.
Installing CyanogenMod 11
Required Files: CyanogenMod 11 ZIP, USB Drivers
** - Get the CyanogenMod 11 ZIP from https://download.cyanogenmod.org/?device=ls980 I recommend using the latest SNAPSHOT – get the NIGHTLY only if there are problems with the SNAPSHOT.
1. Place the CM 11 ZIP on the root directory of your internal storage.
2. Power off your phone (without it plugged in).
3. Turn on your phone holding PWR+VOL-Down until the screen says “Recovery mode”
** - The screen may say something about a factory reset, in this case press the power button 3 times and you'll be brought into recovery.
4. Tap on install
5. Scroll down to the CM 11 ZIP and tap it
6. Follow the instructions and when prompted to wipe the dalvik and cache, select yes.
** - you may have to do an advanced wipe and select everything except for internal storage, but do this only if CyanogenMod doesn't install properly.
7. You now have CyanogenMod 11 on your phone!
**- You will have to install GApps in order to access the Google Play Store and other Google Apps. You can download it using the browser on your phone or by transferring the .zip file to the root of your phone.
**- To install GApps just boot into recovery, select Install, and navigate to the GApps .zip. Swipe to install.
If you have any questions or any issues, just let me know. Not everything is accurate as I don't have access to Windows right now so I'm going based off memory. I plan on reinstalling Windows 8.1 Professional and making a video to go along with this. If at any point throughout this walkthrough you find inaccurate information or something goes wrong, let me know and I'll help out/update the article. Good luck!

Thanks so much for your sharing this. I have downgrade my phone from ZVD to ZV7 and get it rooted and CM11 installed. However, I found CM11 is not stable and my GPS module didn't work now. Could you recommend a everyday-use ROM with tethering capability? Many thanks.

I am using the same ROM as yours. I will flash back to Stock ROM and if the GPS still doesn't work, I have to contact LG to get a replace one.

Can U help me with this....
I have LG G2 LS980ZVC Rooted device, and SuperUser is installed.
I want to migrate from stock ROM to CyanogenMod ROM.
But I want the device to work as of the LG G2 D802 (International).
As I will be using it in INDIA (GSM 850/900/1800/1900).
I am very much new to Android and confused to pick the ROM and about the installation procedure.
Seek expert advice about this concern.
Plz suggest... ( attach Hyper link of threads / Videos about the procedure of installation and ROM download link while replying).
Thanks in Advance.......

AJ, I will do some research as to unlocking this phone. I am a bit busy right now but I'll reply by the end of the day.

This phone is already unlocked and works fine with Indian SIM
This phone is already unlocked and works fine with any Indian SIM. I Just want to migrate to CyanogenMod ROM.

I can't find any information regarding unlocking on CyanogenMod specifically, but maybe you could do the same steps at: http://forum.xda-developers.com/showthread.php?t=2655133 after you follow my instructions to install CyanogenMod.

Never, I repeat NEVER flash or install ANYTHING that is not specifically for your phone!! This is the fastest way to brick your device, possibly permanently. I understand that you have already unlocked your phone, but you've done so on a stock ROM. What I was saying is follow my instructions to install CyanogenMod (the LS980 version) on your phone, then (re)unlock it following the instructions at the thread I linked to. I'm not sure how to unlock on CM11, but it can be done: LG G2 LS980 GSM UNLOCKED!: http://youtu.be/r8XCpm046-k

I did try and after a lot of got it to work CM11, you only need ZV8 modem/radio.
Had problems with the GPS even try a lot of apps none of them got it to work, then change the gps.conf file for the orginal LG conf and worked great. The only ROM that the GPS worked since the start was PA all of the others are based on CM so the file wont work, at least for me.
The gps.conf file its on "etc" folder.
CM really its great but to me Omni and most of all that i try in this days (trying to get a good GPS just to play Ingress) Its PA
Good luck

I've never had an issue with CyanogenMod. If you wipe before you install and don't do anything funky with it you shouldn't have a problem. Following my instructions CyanogenMod works flawlessly (for me at least).

I am in the process of resetting everything back to stock. However, I was reading other articles and it mentioned that you must choose the correct files that correspond to either the 16gigs or 32 gigs. In this set of instructions however, it only provides users with one zv8 file for download. I just don't want to mess something up by using the incorrect files. Would appreciate someone's help. Thanks

I have seen what you're talking about elsewhere but I don't believe that this applies in this situation. I have the 32GB LS980, and haven't had an issue, still have all my storage space. From everything that I've gathered from the internet when learning how to do everything a wrote the size doesn't matter. If you're still concerned I can do some more digging, but I don't think you'll have a problem.

[GUIDE]How to install latest Marshmallow KDZ on the LG Spirit

Hello, as some of you may already know, we can't flash MM kdz on our LG Spirit using LG Flash Tool, so we have to use LG UP, a method which is also used by LG G4c owners. I drew the idea from them, since G4c and Spirit are practically the same devices. I've modified a script from G4c, all credits go to @bender_007.
So here are the steps:
1. Make sure you have USB drivers installed.
2. Download and install LG UP: http://www.filedropper.com/g4 ---- First install LGUP_8994_DLL_Ver_0_0_3_23, then LGUP_Install_Ver_1_14_3.
3. Download the script that makes LG UP recognize our device as H440n(Courtesy of @bender_007, I only modified small parts of it). Link: https://www.dropbox.com/sh/lbxdwloffi75qqg/AABfz5e9AIiSxipsnZQIiikGa?dl=0 (Download as zip)
4. Extract the zip and run h440n.bat
5. Connect your Spirit in MTP mode.
6. Run LG UP and wait for it to load.
7. Leave all settings as they are.
8. Under file path, browse to the kdz file you downloaded. NOTE: It won't show in the directory it is in, because the browse window sees only .tot files, so you have to manually type in the KDZ name in the text field and select it that way.
9. Click Start
10. Wait
11. ???
12. Profit! Enjoy your LG Spirit running Marshmallow!

Thanks, I had to manually copy the dll in the LGUP folder, dunno if it's my fault, or script's fault though.
EDIT: It gives me an error on boot, about CUST not existing... Nothing important, I can continue to use it but it's rather annoying? Fixes? Thanks.

I suppose yours, because it worked for me flawlessly. If someone notices any errors in modifications I made to the script, feel free to correct me.

Depending on OS and security level it can happen, it might need an elevated access- Try: right click - run as administrator

Had to also copy everything over manually, running as admin didn't help. I haven't done anything to my security settings and am running on the only account that was created with the install. I think it might have something to do with me running on dev mode though.

nah, I also run dev mode. No worries I'll create a desktop app which will then work.

Afternoon fellas. I have reached the part of runinng the kdz via LGUP however the kdz i have (named H525n20c_00_0321.kdz) brings back an error of invalid kdz. Could someone be so kind as to point out a working link for the kdz if possible?
Thanks

Firstly, do you have LG Spirit or LG G4c?

guglicap said:
Thanks, I had to manually copy the dll in the LGUP folder, dunno if it's my fault, or script's fault though.
EDIT: It gives me an error on boot, about CUST not existing... Nothing important, I can continue to use it but it's rather annoying? Fixes? Thanks.

Wait until H440F kdz is released.
P.S.: I had to copy all files manually and manually Merge registry script. Probbably some Windows 10 BS with UAC and bat scripts lately.
Another BS, now from phone - MSC error on boot. But that temp root isn't availiable :/

Regular mode what is enabled by Deafult on KitKat and newer ROM's. It is also known as Media Transfer Protocol and when you connect phone it should look something like this (screenshot from my PC with my current device connected because of copying nandroid backup to PC)
Antoher note: for LG Spirit it looks like Phone Icon, not Media Device.

Yes, you can get back by flashing kdz using LG Flash Tool and as far I saw there isn't enabled Adoptable Storage.

Can you do the same for the LG Spirit h420?

To anyone interested:
I got adaptive storage to work! It's pretty simple. Just follow the guide from modaco.com (search for "modaco adaptive storage galaxy s7" on google", I don't think I can post links).
Then go to Settings -> Storage & USB -> Your SD Card -> Merge (in the additional menu).

Honor 7X with installed TWRP bricked by OTA update ... any help?

Hi,
the first time after years of installation of custom roms ... seems it happens to everyone once a while. What happened? I installed TWRP and Magisk with a bit of trouble but finally it worked well. Put the box aside to finalize installation a day later. During the night an OTA update came in together with a Magisk v15 update. So in the morning not really fresh in my head I looked on the display, thought it was my son's 7X (which is untouced on stock rom) and accepted installation and reboot ... BAMMM ... only the line "Your device is booting now ..." gets added to the unlock message screen, that's it. TWRP can still be reached, it is the only mean of shutting the box down, since holding down the power button until shutdown gets it back to the boot screen.
AH ... just for completeness: It is a BND-L21 ... or at least it has been one.
Update: After another night just laid down and switched off even TWRP is gone, now the EMUI recovery gets booted. No way to shut down the device besides let it drain the battery. I have no idea what this piece of crap will do after next reboot.
Already checked: There is currently no way to download the stock rom. And also the EMUI recovery can't locate a downloadable package on the servers.
Second Update: I still can reach TWRP by pressing all 3 buttons together during boot. By this I can get to bootloader and it gets recognized by fastboot on connected PC. But the EMUI resore kicked in again and now TWRP is again on just Vol+ together with PWR. TWRP is not able to save the settings (e.g. TZ). Is there a corrupted file system responsible for some of the issues? Power off initited by TWRP can only be reached if no charging USB cable is connected.
Any help or any idea? Tnx in advance. :good:

Restoring the backup is the only solution it seems.

Yes ... hmmm ... backup ... that was what I intended to do that morning when the BAMMMM happened. I really had a bad start with the 7X ...
So in case someone has a backup of a clean or nearly clean system partition, please send me a PN. Tnx in advance!

Normal make a Backup in Twrp before modify the System Partition.
Make not an Official Ota Update with Rooted and Twrp installed Rom

Its not the phones mistake that you mess up and wakeup and take the phone for a spin in half sleep
and bamm, i really dont know what that meant. i would say go to the honor care center and get it to them to work.
the procedure which i know of is tough and things like bamm happening might worsen things like TWRP not starting at all.
i have seen people bricking their phones but its never the phones fault.
i would never recommend doing a "BAMM" thing doing and flashing all the stuff randomly cz i dont think magisk is supported fully yet to our phone and you flashed it without asking anyone.
the other russian forums are flashing chinese stock firmware which is the only original firmware available, but the task to change the settings to work for other variant is a huge stock which i gave link to a few people but for you i wont recommend that cz obviously your situation is totally different so go to the honor center and explain them and they would help you.
good luck! next time verify and be careful before flashing anything at random cause its not the phones fault.

Thanks for help, guys. Really ... even though it helped me not a single bit.
My activity has obviously not been on purpose. 2 phones, both looking exactly the same and they are without any apps so far. Since TWRP installation did not went smooth I will not tweak my son's device, therefore even if I have a second device more or less available, I will not touch it to get a system backup. And yes, TWRP backup should be the first thing to do but I have not had the time at that moment. So ... it is the way it is. Magisk is been described as a recommendation at another site, therefore I put it in also for the root hide functionality (my son loves Pokemon go, which will not run on rooted phones), because I wanted to try it first on my phone. Bad luck I would say.
And yes, I'm quite clear about the fact, that the computer just does what you tell it to do ... if you ruin the areas where the OS is located, then it is your own fault and not the device's. Nevertheless it freaks me a bit.
I am really looking forward for a nice AOSP or LineageOS version for the 7X. Oreo or Nougat, I'm fine with any of those. But I would expect, that this will take some time.

Im sending u the link and use google translate but obv.. No one from xda can help you if its from another forum.. Test if you want to at your own risk.. Good luck.. Or wait for a release

I am in contact with the user who posted the article and tested it himself and requested a proper one in english language but he is busy so it hasnt proceeded.. But soon he ll be free to write one up for me so i will post it on XDA..

I'm in a very similar boat. The Magisk v15 update bricked my L24. I had another one available and have made back ups through twrp to restore on the bricked one. It actually boots, but all I get is a black screen with the menu, home, and back buttons now. Holding power gives me the options to restart and power off. Hope they release the stock rom soon, or custom roms be available soon.

root your son's 7x, make a boot and system backup and restore that in your phone.
reboot

Back to life ... at least about 80%. Rooting leads to corrupt system partition (unable to boot afterwards) and bootloader can only be reached while a USB cable is connected (unusual behaviour). Nevertheless ... got it running. SID ... you are my hero of the day. Will PM you regarding comments for your thread.

i think i have to write a guide now. this was the first but more can come soon enough. may be today i'll write a guide to backup your phone (all 48 partitions) and then root so you always have all the necessary files to restore it back to life.

So why are you even asking me for a custom rom?
If you know no one has made yet

UPDATE ... got it back to life, at least partly. The only thing is, that constantly the android adaptions of Huawei is making it unnecessary complex or is stopping progress at all. This is the log of my actual tasks. Key to progress was the unlocking of the system fs, which has some inconsistencies in the file system. In general, it gives me a 7X, that boots and I can install apps via HiSuite. Nevertheless I have no idea how to deal with Gapps. If I install opengapps, I will not be able to register an account - just hangs for a long period and then comes back (are there any logs written on the device to analyze a bit deeper?). Gapps without an account maks no sense. So I tried it without opengapps but with installing play services via HiSuite, granting rights, rebooting twice, installing Playstore, granting rights, rebooting twice, but starting Playstore after this procedure just tells me, that gms has to be installed (which in fact is already).
Any hint?

Bricked Phone After Magisk Install

Today, my phone got bricked after I installed Magisk, am i am looking for a way of sorting it out. The phone was running Android 9 DP3 when rooted, and I was following HighOnAndroids root guide on Youtube for reference,
I unlocked my bootloader and successfully installed TWRP. After this, I installed Magisk, which went throuygh perfectly fine. However, after rebooting the phone, I am stuck on the google splash screen, with a small progress bar that stays for the duration of the time on this screen. After about 2 minutes, the phone reboots into TWRP again.
Does anyone know how I could return to stock Android or at least escape this issue?
Many thanks
James

umph....hate to tell you, but you have a long way to go...
so before going on this "journey", I would suggest you booting into TWRP again, and try installing (not adb sideloading, just in case you're doing that) Magisk again. Also, be sure you are using the latest (might be considered "beta") 16.4 for taimen... I'm thinking your boot.img or dtbo.img simply may have gotten glitchy and repatching (by installing Magisk again) might fix it...
Also, if you want to go a step further, you might want to consider using the official Magisk uninstaller. Since Magisk makes a copy of your stock boot and dtbo image, it may put that back so you can get it in working order to get into the system (although without root), and then figure things out and/or reinstall Magisk (through TWRP is best) while all things Magisk was removed...
Good luck and hope this helps....

Make sure you are trying to open from the correct location, and put .\fastboot

With the unlocked bootloader it'll always say the device is corrupt. Manually put the device into the bootloader & flash the DeucesScript. You're basically starting over at this point but it is possible to get up & going again.

EvilDobe might be right...but I have a bit to offer before maybe starting all over...
I doubt you needed to edit the script and "change the paths." Most likely you merely did not have the images (you extracted from the .zip of the Full Factory image you got from the Google Developers site) inside the "platform-tools" folder with the adb & fastboot .exe and all the other files and folders.
In any case, I suggest you get the TWRP image file [.img] (NOT the installer .zip necessarily), put the .img file "... inside the "platform-tools" folder with the adb & fastboot .exe and all the other files and folders." (I've seen some users simply cut and paste those 2 .exe files only to the extracted folder -- this is why I state it this way) Then, power down your device. After it's off, hold down the Volume Down button and press & hold the Power button (this is the manual way to get into the Bootloader Mode). Once there, plug your phone into your computer (USB-A to USB-C would be best) and open a command prompt/powershell ("run as administrator" or with administrative priveleges) and direct it to the platform-tools folder (i.e. if I put it on my desktop, it would be "C:\Users\MyName\Desktop\platform-tools"), you can temporarily boot into TWRP via command
Code:
fastboot boot twrp-3.2.1-2-taimen.img
When in TWRP (hopefully), I suggest trying to do what I advised before -- try either Magisk installer to repatch the boot and dtbo image, or Magisk Uninstaller to attempt to replace your boot and dtbo to stock.
*NOTE: Of course, this is assuming you are running Microsoft Windows (if not, you will need to input .\ as @naiku suggested) and also the whole "device is corrupt" is due to "funky" boot image issues. If not, I/we can guide you to flashing the Full Factory back onto the phone (hopefully without losing data and settings)...
Good luck and hope this helps...

I wouldn't go that far with staying away. When I come across people IRL that want to start doing this stuff I always tell them to read the instructions, step through them, read the instructions again, ask questions (as you did here) BEFORE you get started, read the instructions again, and only when you're confident start messing with your device. This is a fun, and at times stressful, hobby. It's great when everything goes according to plan but it's an omg omg omg omg omg omg moment when you mess something up.
Start with baby steps. The straight upgrade to P is fairly simple provided your device is unlocked. Get that working & you'll be set. I have root on my DP3 & the only thing I've done so far is delete some apps from system that I know I don't want/need. If your main goal is to just enjoy your phone, test out Android P, and maybe go back... root isn't needed. Once everything is squared away & you're running for a day or so you can always fastboot to recovery, make a backup, and then try to add root. I hope you don't shy away & get deeper into the hobby. It truly starts to get fun when you begin to understand more of what is going on.

When I come across people IRL that want to start doing this stuff I always tell them to read the instructions, step through them, read the instructions again, ask questions (as you did here) BEFORE you get started, read the instructions again, and only when you're confident start messing with your device. This is a fun, and at times stressful, hobby. It's great when everything goes according to plan but it's an omg omg omg omg omg omg moment when you mess something up.
Start with baby steps. The straight upgrade to P is fairly simple provided your device is unlocked. Get that working & you'll be set. I have root on my DP3 & the only thing I've done so far is delete some apps from system that I know I don't want/need. If your main goal is to just enjoy your phone, test out Android P, and maybe go back... root isn't needed. Once everything is squared away & you're running for a day or so you can always fastboot to recovery, make a backup, and then try to add root. I hope you don't shy away & get deeper into the hobby. It truly starts to get fun when you begin to understand more of what is going on.

And it's as @EvilDobe means.....
I remember back in the days of the Motorola Droids (OG Droid1, Droid 3, & Droid 4) where you could really mess things up and come out with a big ol' "brick" "paperweight" as there were many instances where you could not come back from (i.e. updating to a certain point, then attempting to downgrade when Google/Motorola/Verizon put blocks that breaks it). But this isn't the case these days. @Jameswebb97, at least with the Pixel 2's, Oreo and/or P(Android OS 9), it's actually more difficult than easy to get that too far gone. The only reason why I can help so many troubleshooting their issues is because I, myself, have wrecked my current device in some serious ways! So I can relate and have experience in helping in the same situations. I've gotten it to where it says "device is corrupt," (which isn't all that uncommon), BUT with the added desperate troubleshooting where I had to wipe/erase, changing partition types, format several partitions, even go about "resizing" the partition to match the "target extraction size" of the Full Factory flash, and even as far as learning to manually flash the various system partitions and that there are two (system_a & system_b) but, in Google's infinite wisdom(?), one flashes to system_a and the other to system_other!!! And I haven't even started on reading others' issues when going after the Slot A and Slot B complications -- I didn't even attempt to touch this in that troubleshooting story.
My point is: I think I've broken my device farther than most people and got it so close to the brink, and yet I was able to bring it back and am still using that same device today (most people would usually, at that point, go and get a RMA replacement). Honestly, as long as you have access to Bootloader Mode (which Google, in their infinite wisdom, seems to have placed it in the main board memory or separate memory rather than storage as to make it always accessible which makes it hard to "lose"), you have a really good (seemingly perfect) "safety net" in which you can always flash back to a working, stock state -- which is why it's the best policy to just make good backups before experimenting so, if anything, you get back to this state and restore all your data. I'm not trying to convince you to root or to try custom ROMs or anything -- even though there are many great reasons and capabilities of rooting -- I am simply appealingl to your sense of curiosity and reassure you so you aren't held back and you don't restrict and limit yourself if you don't want to, but are to fearful to experiment.
I hope you don't take this post as "lecturing" or anything, just some thoughts I hope you consider...
Glad it worked out in the end for you!

DId i Brick my Samsung Galaxy A505FN?
Hello one Question:
"did i Brick my device if for some reason after Trying to flash TWRP it fell back in to OEM-locked and i’ am now in a Boot Loop, ore is the any Hope?
I used Heimdal and at first it did the Job but then it would not start again as expected.
After some attempts to flash it Properly it suddenly fell back in to OEM-Locked!
Pleas if you now some advice it be greatly aprichiatet
My device is a Samsung Galaxy A505FN (Spain)

I found a way to Unbrick my device
Just to let anyone that pass her know i finally found a way to unbrick my device here it is:

All i know in case of my Samsung Galaxy A50 it is Possible!
To lift the OEM-Lock mode again.
i do not know if that is true for every Device.
Ultimately i was successful to install full Root-access!
I had great difficulty tho to use Heimdall ore any tool on Linux so i ended up using Odin in a VirtuelBox with WinXPpro
but do to no support of Long file names i had to trick there, to to make it work.
I just shorten the Names of every .tar to the first 2 letters.
I was able to successfully flash TWRP with Heimdall but not the Android ROM for my Phone.
I still wonder how to make it work!
There was one Thing i Noticed when Using Odin it seams in the Process he flashes vbmeta.img twice.
That impossible with Heimdall it creates a error message.
Well if anyone - that passes here - knows how to flash a Android 10 ROM of a Samsung Galaxy A50 using Heimdall let me know i tried very very hard to no avail.
I was surprised to learn there is no Good Tool for Linux-user doing this Task.
i only found Old Tutorials!
Is it truly possible that Heimdall dose not support modern Phone-flashing anymore properly?
As of now if a Linux-user ask me about Rooting i would advice him/her to do it in a VritualBox with windows installed.
If you have a License of a Windows Version Higher then XP good otherwise you have to Shorten File names if the very long to make it work.
I scarcely use windows anymore that why i only have a old WinXPpro legally in my Possession.
Unbelievable that the Linux-Community should not have a modern Flash Tool!???

Hello to @everyone
I had great difficulty to do this as a Linux User using Heimdall and eventually had to give up (after trying for 3 full days)!
I ended up doing it using Windows out of a VirtualBox!
It was Possible tho to successfully flash TWRP using Heimdall!
It also showed Success when Flashing Android 10 Version for my Phone but would not work.
Using the same Firmware with Odin it worked just fine.
When i compared the Flash-Protocol of Odin with what i did i only Noticed that Odin would flash vbmeta.img twice in the Process something that cant be done with Heimdall as it produces the duplicate error.
I wonder if this is the Reason it would not work.
I was also surprised to Learn, that there is virtual now Tutorial out there using Heimdall on a Modern Phone (last 12 Month ore less).
Is it truly Possible that There is now good solution for Linux Users?
I also Looked in to Fastboot and ADB and other Tools for Linux Platform and they all seam to be outdated!
Also all this Tools could not accomplish the task at hand.
Now if its me and anyone knows how to make it Work on Heimdall let me know as it is a Pretty good tool after all and by now i know it well. I would gladly start to make a tutorial and provide it here for free if i know how to make it work.
I have a txt file where i made a complete Protocol of all i tried if someone is curious ill send it to you.
Saludos Hans
##################################################################
I send some more Details of my Challenge in hope someone my know what it is i have to change!
My Device:
Samsung Galaxy A505FN
I created a .txt file protocol of all i did, i gladly provide it if someone ants to see it.
I analyzed the Whole Firmware-archive and the Pit file of my Phone to eventually find the Problem.
Note:
The Firmware was the correct one as it worked just fine using Odin!!
Analyzing all this, i only noticed two things:
First:
There are 3 seemingly identical files in the Archive and two so called
fota.zip files witch are not Identical
(one in the AP-Packet and one in the CSC-Packet)
Those where:
– cache.img one in the AP-Packet and one in the BL-Packet
– vbmeta.img one in the AP-Packet and one in the BL-Packet
– product.img one in the AP-Packet and one in the BL-Packet
Second:
Once i used Odin to finally flash successfully i noticed that in the Flash-protocol of Odin it seams Odin flashes the vbmeta.img twice in the process!?
Heimdall would not allow me to do so giving me the “Duplicate Error message”
Furthermore i tried one more thing in my desperation to make it work:
i thort: “maybe the order in wish the files a flashed chronologically matters”
So i did exactly that, trying to flash in the same chronological sequence as Odin did.
Note:
Every time i flashed, Heimdall would successfully finish the process but the Phone would not start with android
no matter what i tried.
ALSO i did successfully flash TWRP to my Phone using Heimdall
SO Heimdall works just fine on my system!
I spend a Long Time searching the Internet for a workable Tutorial or glue’s as to what is missing and how i could make it work.
I really want to succeed doing this, as i want to provide my folks offer her in Germany and also English and Spanish speaking Linux-Community with a Tutorial to do this!
I did also drop this Question and Challenge i face in some other Forums no useful answer returned so far
The latest Governmental Abuses and infringement on Peoples Privacy using Corona as excuse, makes it abundantly clear how important this kind a work is!
As for now i think, the only true option for a Linux-User is to run Odin from a Virtual-Box Windows installation, given
you have a legal copy in you're possession and have higher then Windows XP
(else you must change the Filenames of the .tar archives as WIndows XP and lower did not support excessively long filenames.)
Also you have to Install you're Phone USB drivers and have them up and running properly!
Internet access to you're VB makes it all more comfortable, but you can also use Shared folders with the Host-System to do the job.
Note:
I did indeed tried the "WINE-plugin-environment" (Windows 10) under Linux. i could not get it to work.
It was to much messing around make it recognize the USB-connection to the Phone!
I could not get it to work, I don't know if you can?
I guess that would be a nice way for Linux-users if it could be made to work!
What do you guys think, can this be solved?
Pleas let me know if you know the answer to my Challenge!
You're help is not only needed but would be greatly appreciated
Sincerely yours
Hans from Germany

well I Found this from 2017;
Yes you can do fastboot and adb cmd in Linux but you have to install adb and fastboot drivers to Linux by using
1) sudo add-apt-repository ppahablet-team/tools && sudo apt-get update
2) sudo apt-get install android-tools-adb android-tools-fastboot
That's it you get your fastboot and adb cmd’s all the cmds are same just as windows just you need to add sudo in front if not in root

so maybe have a read of this too; https://android.gadgethacks.com/how...actory-images-android-using-fastboot-0175277/

Well i do know
Of course i know how to Install a Software on Linux and i did indeed installed those Two
But both of them would not even Detect my device jet Heimdall and Odin had no problem doing that.
Anyhow i might go about and try those Two harder.
And no Iam not confused
thank you anyway

USB File Transfer Does Not Work
After flashing the ROM, when I connect my phone to my PC with the USB cable to transfer files, it does not work. No errors on my PC. I tries switching between modes and back to File Transfer as some suggested, but no luck.
Has anyone experienced this and if so, any solution?

This is what you get with a GSI, finger print wont work either.

Actually it's the only Custom ROM where the finger print works. My only problem was with the USB File Transfer.
