Hi everybody,
I'm fairly new to the android world and I don't know a lot about modding. I flashed Cloudyg3 1.3 mod about a month ago and everything went well, but today I wanted to upgrade to 2.0, so I entered in recovery mode using Autorec, as usual, to backup my phone. The backup was ok, then I rebooted my phone and it stuck to security error. I didn't flash anything yet, so I really don't know what may have possibly caused this error.
I even tried to enter recovery mode again to wipe data, dalvik, etc, but when I reboot I still get this error.
Any help?
I solved wiping everything but internal storage, and then using ADB Sideload to flash the CloudyG3 ROM.
@Unichord good to hear that you had fixed your problem, the security error is most time that if you remove or change files that it shows security error, its implented in the kernel ony I believe not in the rom.

I understand that, if I was flashing a rom, or kernel or everything else I would be fine with it (maybe I would have done something wrong), the problem is that it showed up just after a backup! I really don't understand why it did happen.
Thank you anyway for the info
I'm Sorry guys but if I didnt reach a desperate state i wouldn't be posting this, at first i posted this at the nameless rom section thinking that its only related to it, but now i think there is something im generally wrong in the steps that im doing but i just cant figure it out
and before anyone says anything, Yes i did try hard to search and read as much as i can about the problem before posting here, and Yes the solution might be very stupid and i missed it but honestly after flashing my phone soo many times i decided that just like my phone.. i'm looping with no way out :S
Anyhow, to begin with this problem is only happening when trying to flash the Nameless V4... and i have the SM-N910W8 ... and before all this started i was running the Nameless LP v7 (?)
How did i reach this point ? here are the steps :
*Did all the backups needed
*Flashed the phone using Odin to the latest 6.0.1 Stock rom : N910W8VLS1DPK1
*Flashed the latest TWRP
*Wiped System, Data, Cache and delvik
*Flashed Nameless V4
*Flashed Emotion Kernel R25 Rc1
*Flashed the latest SuperSu which is 2.79
and then reboot
at first no matter what i do i could not go past the first screen which says : Galaxy Note 4
what i did to TRY to resolve this issue:
*redo same steps but different kernel (didnt work)
*went back to an older stock 6.0.1 via Odin which is N910W8VLU1DPE2 (didnt work)
only after i re downloaded everything and made sure no file is corrupted, that i started seeing some progress
So at this moment, i can get the phone to boot on both emotion and H-vitamin kernel, but no baseband or IMEI.
Also when i try to install the data fix, i get stuck in a bootloop
If anyone can please give me clear steps to get this over with i would really appreciate it, i dont have any other phone to use at the moment and i cant use my phone in this state
Thanks in advance
NEW UPDATE :
I managed to get all the files i needed to flash working, the only problem i was facing was with the Data fix file and every time i flash it, i end up with a bootloop, so after researching, i ended up replacing the build.prop of the Data fix file with the build.prop from the Nameless v4 rom, after that i flashed the new file, wiped both caches, and after a long wait since i cleaned install everything, phone booted normally, of course i'm still facing the no baseband/imei/sim problem, but atleast there is progress.
I dont know if this information helps anyone but i thought i should mention it just incase.
I think im gonna try testing with the v3 and see if i can get any sign of life when it comes to sim/baseband/imei......(update.. no sign of life)
Just to give an idea on where i am right now, the only way i can get the phone to function normally is by flashing any stock image
You are literally the only person on Google even talking about N910W8VLS1DPK1, so I figured I'd ask you: Did your problems come from updating to DPK1, or are they a result of the custom ROMs you're trying to install? Because I want to upgrade to this version, but not if it breaks everything. I'm just looking to update to DPK1, root, and debloat, maybe even install a debloated ROM if there is one, that's it.
I tried Nameless and couldn't get it working on the Canadian version. Im not sure if it had to do with not having a datafix. But my result was the same. Unknown baseband.
Yeah. I was trying to unlock my bootloader using Controllerboy's guide, and I managed to install TWRP. I also managed to unlock my bootloader. When I tried to restore my phone using the backup I put on my computer and back to my A7, it won't boot - it's stuck on the "ZTE powered by android" boot screen.
I think that the problem is that when I was copying the backup from my phone to my computer it said "unspecified error" but still let me copy the files (the files and the sizes remained the same) so I just ignored it. Whoops!
So I tried to install CM13 in hope that it will somehow fix things, and unsurprisingly everything is still the same.
So. What do I do? I think that the problem was that I backed-up system and tried to restore system (probably).
Anyone got a solution? Or even a system restore that will cure my phone?
Any help will be greatly appreciated! Thanks in advance!
I managed to solve the problem myself by re-wiping dalvik and installing CM 13! Odd that it worked this time and not the other time I tried it, but at least it works

this is normal and a search would have told you the solution after the phone boots up all the way cover the sensor by the front camera turn off the screen once the secondary screen goes off turn the screen back on
I have this problem when installing lineage os cm 14.1 20171205 and now when I install any custom rom now on my t-mo lg v20. How do I know when the phone is all the way booted up though after the flash of the rom?
Without fail every time after the lg logo disappears after flashing a custom rom made for the h918 lg v20 I get a flashing black screen. I'm doing a factory reset/wiping davlik cache/ cache/ and data 3 times each time I flash the custom rom and sometimes I even go as far as wiping the internal memory completely even after a factory reset but no matter what I try without fail I always get the flashing black screen right after the lg logo disappears. I even tried upgrading twrp from 3.0.2.0 to 3.1.1.0 and I even tried flashing the no-verity-opt-encryption 5.1 and 6.0 but nothing I've tried seems to fix it so I'm asking for help now since I've exhausted my knowledge on what could fix it. What can I do to fix that issue so I can finally start using custom roms again? Any help would be most appreciated thanks in advance.
P.S. The only rom I could get to flash successfully was the stock twrp flashable t-mobile rom on one of the threads in the rom section of the lg v20 forum so for now until I can fix that issue I'm currently running that so I have a phone I can still use.

did you ever find a solution? I'm having the exact same issue and am pulling my hair out trying to get something to work
If the version number of twrp your using is in fact 3.1.xx then that could be your problem all the new roms im almost positive need the newest twrp from pheonix i think it 3.2.3.4 its in the deveopment section...ive heard alot of problems on this device with older interations of twrp. I would start there

Official lineage 14.1 only works with pre10p h918, some firmware blobs need changed.
I just built an unofficial for my own use a few days ago that should work, but I havnt gotten around to testing it yet.
lineage-14.1-20180721-UNOFFICIAL-h918.zip
lineage-14.1-20180721-UNOFFICIAL-h918.zip.md5
When lineage 15.1 becomes official the h918 builds will be aimed at post10p. x86cpu is currently doing unofficial builds for both.
