I have been flashing this afternoon trying to find a ROM that meets the following needs (without going into too much detail), but have not been able to find one that will will work without bootloops.
Basically, I am looking for a CM12 5.0 ROM that supports the AK kernel with working encryption. BlissPop has been badly buggy for me since late February, and I just tried with Temaseks 8.8 (last android 5.0.X version, still supports exposed) twice. First time tried to encrypt after flashing latest AK kernel and UKM zip, but my OPO would just reboot without encrypting. Then I tried flashing on a new clean install after encryrpting, and got a bootloop. I have also tried this on some other ROMs, even some F2FS ones but it didn't work (I don't think encryption works with F2FS).
Any help would be greatly appreciated. I can give more details as necessary. I never post on XDA, but I am by no means a novice to Android or flashing.

I have a TF300T with the latest bootloader and twrp 2.6.3.1. I had been installing nightlies for CM11 and using Grimlock kernel and had zero problems until the first nightly after Snapshot M4. Ever since then, after flashing a kernel on any CM11 as soon as it reboots into android I get the message in the title line.
I have tried wiping everything and it still happens after installing a kernel. If I just install any copy of CM11 and GAPPS everything works perfectly fine. It's only when installing any of the aftermarket kernels. I even tried using the latest Philz Touch 6 and still get the same problems. I have searched on Google and find plenty of people asking for help on the same error message for different devices but nothing on how to fix it. Does anyone know what this can be?
Any help will be greatly appreciated. I like our tablet with CM11, but it is SO much better being able to overclock.
Thanks,
Rick

Free gift from Grimlock. It's the kernel that restarts 3 times before fully booting, right? As soon as I took it off my system, the problem vanished. Comes with the package. You like Grimlock, must learn to live with it. I don't like it That much.

Updates have come that fix that problem. Same with Geass, if it's not fixed yet it will be VERY soon.

Or you could file bug reports with the devs, and guess what? They found the problem and fixed it! Instead of slagging people who are trying to improve our tablets, you could help them by letting them know about the issues you have.
The "free gift" is the kernel that's posted for a community. If you don't like it and don't want to help, and would rather tell others bad things about it, then take your nonsense somewhere else.

I upgraded to the latest TWRP 2.7.0.1, deleted everything and started from scratch. Everything works great now and using new kernel that clocks to 1.8 is flying.
Hello and thank you for viewing my thread!
To start, my device is the OnePlus One, and i am running the latest Release of CyanogenMod 13 with the Latest Lightning Kernel for it's kexec/hardboot patch
I have tried multiple times, installing the multirom files, as well as flashing a factory image and flashing from a fresh install. Nothing seems to work.
The exact problem would be, even after performing the inject boot sector action, multiboot or the boot menu fails to appear.
I have no idea how to view kernel logs or anything of the sort. However i will gladly provide any logs or files if needed! Ill just have to figure them out is all.
Any help is greatly appreciated. Thank you in advance!
Edit:
1. I think i have the kernel ruled out as the problem as i have already tried a modified stock kernel, as well as bouffla's kernel.
2. The rom also doesnt seem to be the problem as i have tried both COS 12.1 and CM 13
3. The recovery seems to be ruled out as well. I rolled back to a previous version of TWRP and still have the same issue, no multiboot menu after proper installation.
4. This is really confusing. I even tried using the files built into the multirom manager application and that fails as well.
P.S. (on a semi-unrelated note)
I currently have a strong feeling it is a very low level issue (at least for my experience) due to the fact that kali nethunter is also failing to install and causing my device to brick every time i attempt an install.
tl;dr - TWRP touch screen won't work after installing custom ROM, much hassle to unbrick, looking for a "bumped" (still not actually sure what that term means) or otherwise modified version of TWRP that won't go haywire when installing a custom ROM.
tl;dr 2 - Also interested in the LATEST "stock-based" ROM recommendations anyone may have... G3 backports or whatever. She needs her Camera to work well but older 4.4.x and 5.0.x OS is missing a lot of new functionality and compatibility with new apps.
I'll just start out by saying that I've figured out just about every way to brick and subsequently un-brick this device that is feasibly possible, and am considering starting a thread specific to those various methods... but that's not what this is for.
This is an issue I've encountered a few times now, definitely on my girlfriend's T-Mobile LG G2 D801 with Lollipop (30B and now again on D801 30C), and iirc, also on KitKat.
I'll explain what I can remember, most of this has been done in the middle of the night after many frustrating hours of attempting various methods... I have to say, this phone has been much more difficult to mod compared to my previous experiences with Samsung and Nexus devices.
I had gotten this device all the way through to CM12 or 13 a year or so ago but recent issues made us decide to attempt to revert back to a Stock-based ROM.
Steps:
1. Root (ioroot / Autorec, can't remember which or for what reason, I have multiple versions of each)
2. Install TWRP Custom Recovery (most recently and successfully using a modified version of the "30B Freedom Tool", although I haven't tried that on 30C - yet.
3. Transfer custom ROM & Kernel to SDCard.
4. Boot into TWRP and install custom ROM & Kernel - most recently GoogleEdition 1.5 and then DorimanX 12.0 Kernel
5. Clear Cache / DALVIK Cache.
6. Reboot device. This is where the trouble begins...
Results: Won't boot into OS at all, instead I end up at the text-based "fastboot" screen, which after multiple tries I can eventually get back into TWRP or into Download Mode.
Once in TWRP after installing custom ROM, the bottom ~1" of the screen won't respond and all other touches aren't accurate... playing with it, I can usually eventually get into some of the TWRP screens, but for most purposes it's about useless.
I managed to restore a backup of the original 30B system image via command line over MTP using ADP TWRP commands, but that bricked the phone in an entirely separate manner where I couldn't access Recovery anymore and the system wouldn't boot at all... I ended up using the LG Update tool to get it up to 30C, and was surprised to find that it still had the restored backup data (apps, pictures, settings, etc), and the phone is now working again, albeit back to stock recovery.
Now, as I mentioned, this isn't the first time I've run into this "phantom touch" issue in TWRP on this device, although the circumstances seem to be a little backwards this time vs when I was taking the device over to CM12/13. I think I remember something about a "bumped" or otherwise modified version of TWRP being out there, but I can't find it now or put my finger on what the changes were.
Has anyone else run into this? I am hoping I've just overlooked something, but days of digging through threads hasn't turned up much.
/edit/ To give you an idea, attached is the folder I've got files stored in... with tons more in Archive and Stock-Based... I've used them ALL at some point. I'd like to get enough info in here to write a Step by Step guide for new owners who are picking these devices up on the cheap, and would appreciate if anyone wants to help out with this!
Just signed up here first post to the threads but you guys been helping me out for years different devices programs huge thanks to everyone here.
New to this device I'm starting to really dig it ran couple stable 8.1 ROMs got magisk+systemless xposed running. I previously dualbooted lineage nougat with stock on my droid bionic using safestrap(wanted to add a gingerbread) before getting this phone. I flashed the Multirom Twrp but app said I was having kexec kernel issues then ended up bootlooping os or getting black screen few times ended up just full reflashing cm firmware putting regular twrp back up.
Seen video of multibooting many ROMs( but I assume older non Oreo ROMs) and Ubuntu touch from a flash drive. Is it possible for me to bootup with a safe stock, ubuntu, and a 8.1 ROM(read Aosp extended is compatible but couldnt flash a kernel on top of it)? Couldnt find stock cm 6.0.1 bacon zip was gunna try and flash think it was ap kernel again over that but I tried a couple kernels didn't know which one was the right one.
Is there any newer Multirom alternatives or proper current kernel patch link? Does EFI droid work better could I still get ubuntu? Any advice would be appreciated pointers in the right direction tried to do some digging trying to really superpower my device if I can before I log into my all apps and stuff again. Is this a wild goose chase? Or was I like one step away
*SOLVED: see reply*
The ROM I used before was LineageOS [10.0] and used a custom ROM with Android 9 before that. Needed to unlock my phone, and couldn't do that on Lineage, and had troubles flashing firmware with Odin, so I ended up using FrankensteinS6. The Stock kernel seems to let me input the NCK, and unlock the phone. So that's luckily finally over.
For about 4 days now I've been formatting phone and trying again and again. FrankensteinS6 works, some other 6.0/7.0 ROMs work. But LineageOS now enters a bootloop, and Pixel Experience (9.0 and 10.0) and Evolution X 10.0 don't detect the SIM. The ones that don't detect SIM also show no IMEI, which was worrying at first because I though I lost a partition.
Possibly related, the ROM of Pixel Experience Android 10.0 for G920W8 will not install because (paraphrasing) "This device is zeroflte, this file is for zerofltecan, zeroflte***, zeroflte***" claiming that my phone isn't one of those models. I got this S6 from Bell Canada, and I still have even the sticker that says it is a G920W8, not G920F. However, the Pixel Experience ROM for G920F flashes fine (sans the main problem).
I don't know the exact LineageOS ROM I used before, but I've tried all of their 10.0 releases, tried redownloading, and I get the bootloop every time. I see some info online of flashing modem firmware, but... I don't even know where to start with that. As I mentioned at the start, Odin is crapping out. I couldn't flash firmware with it, because it would reject the phone right after I started flashing. Anything I could do within TWRP would be great. I moved it back to FrankensteinS6 for my sanity, I started doing this Sunday and I'm starting to repeat steps over and over hoping that it just solves itself.
I tried to keep this straightforward, and I'm sure I did a bad job. I can extrapolate on what I have attempted. Please tell me what I have to do to get an android 10 ROM working on this old beauty again.
I do not have all the solutions. As per my tests with my SM-G920W8. I have managed to find ROMS and try them out. I have only seen Nougat 7.0 ROMS to work almost flawlessly. NOT 7.1.2, important, 7.0 only.
I have also tested some Pie and v10 ROMS like Pixel Experience. The ROMS boot nicely but since I do not use a SIM card to call as I use SIP phone numbers and require WiFi. But that left asside, I came upon serious camera issues no matter what I try. Up to now, SamStock ROM is pretty much the best Stock ROM I found but I always need to run the Magisk UNINSTALLER before re-installing the latest Magisk version..
As for Kernels, well, Anything that is oriented with Lineage OS, I've had camera issues even with Nougat v7.0. So basically, the only ROMS I found good, as of today, for now, are stock ROMS v7.0. But, to do your tests, Even if you have a 920F ROM, you can download a 920W8 kernel as long as you download a kernel which supports your installed Android version. Also make sure to download the proper Stock or AOSP kernel (AOSP for LineageOS). There's not many but there's a few ones that work properly.
Another option is to download an AOSP ROM that works for W8 phones, unzip the file and grab the boot file inside corresponding to the W8 or T-Mobile version. You simply unzip your real ROM you want top install, replace the boot file for the one you got and rezip it. This made my phone boot properly for some F version ROMS but again, not without issues. That's why, I really suggest v7.0 Srock ROMS. I hope this helps you a bit. Again, you can have your own tests and other users may have other answers, but this is based off over 30 bootloops in my case of trying to mod a ROM for the W8 model. It's not easy to find a good one for Canada, I admit!!!
I flashed TWRP years ago, and I found out that I had a G920F version flashed. I don't know why Lineage allowed me to use SIM before, but rectifying this issue seems to made the SIM work in newer versions.
I don't know what the S6's predisposition to having crashing cameras is, but I have avoided this in the past by using custom camera apps, like Open Camera. This has saved me every time.
As for the boot loops... I think another thing that helped is that "format data" doesn't wipe the OS. When you are in recovery, having issues with bootloops in various ROMs, try advanced wipe, and wipe the system. It didn't fix right away, but the time I got Pixel Experience 10 up and running that was the trick.
