Out of my depth with MultiROM/TWRP problem; could use some guidance

Hi, All . . .
I believe it would be appropriate to label me as an intermediate-to-advanced newbie. That is, I'm not clueless, but there are lots of blind spots in my knowledge.
I just bought a 6P and while I've been waiting for my SIM card to arrive, I've gone ahead and rooted, installed TWRP 3.0.3-0, and made a few customizations here and there. One thing I don't understand is the significance of the vendor image now. I'm coming from a 6 where that wasn't an issue. Also, in the rooting instructions it indicates that one should "find the correct vendor image," without really indicating how one can go about learning which one is "right." In the end, I took the latest one I could find, because my phone did an OTA update and I simply reasoned that I should match latest with latest.
In any case, I want to install MultiROM and I keep running into this problem:
The MultiROM version of TWRP doesn't load. It hangs on the splash screen. The version it uses is 3.0.2-0, so I suspected it was an issue with that. I flashed the TWRP-only recovery version 3.0.2-0 after having no luck, and it wouldn't load beyond the splash screen, either. Finally, I re-flashed the stock system recovery and tried flashing both the 3.0.2-0 TWRP-only recovery and the MultiROM-integrated version, both without success.
Is there something about the move from 3.0.2-0 to 3.0.3-0 that makes a rollback impossible. Is it even necessary?
Re-flashing 3.0.3-0 solved the problem of basic functionality. TWRP comes right up after I do that. But I can't get the MultiROM recovery or the 3.0.2-0 TWRP recovery to work no matter what I try.
My phone says that the vendor version is N4F26J and my "build number" is N6F26Q, and I'm running PureNexus 7.1.1. Those two numbers appear like a mismatch to me, but everything I could find indicated that the vendor version I have, being the latest, is the right one.
What am I missing? Can someone with more experience solve this puzzle, or at least lead me in a direction where I know which questions to ask on my own and can get things to start making sense again?
I appreciate your help! Thanks!

Hey there,
Regarding your TWRP 3.0.2-0/MultiRom 3.0.2-0 and TWRP 3.0.3 issues, check out post #1152 in the official TWRP 6P thread. If there is an update to MR to support Nougat encryption, you'll just have to follow the MR thread or Github for updates.
Here's a brief explainer from my guide in the Nexus 5X forums about Vendor.img:
9. After updating my ROM, I get this message on every boot: "There's an internal problem with your device. Contact your manufacturer."
This warning signifies a mismatched vendor and system partition. The vendor partition was integrated in the system partition for previous Nexus devices but is now a separate partition that must be flashed for each Google security update. Download a factory image and update your vendor partition using fastboot so that it matches your rom's OS base. If you have a file explorer installed on your phone, you can determine which vendor.img is installed by navigating to /vendor/build.prop and clicking on the build.prop. The specific vendor installed will be a combination of six numbers and letters listed in all capitals (example: NMF26F) in the ro.vendor.build.fingerprint line.
Vendor.img is specific to each OTA and contains proprietary binaries for the phone. The phone will fail to boot if you mismatch the vendor.img with a different OS base. For instance, a 6.0 Marshmallow vendor.img will not allow your phone to boot on 7.0 Nougat.

Hope this clears things up for you!
Edit: Also, certain rom teams keep an up to date listing of vendor.img available on their websites. Usually this is detailed in the rom thread OP. Find a reliable thread and bookmark their vendor.img downloads, if not download the factory image each month and extract the img.

Your vendor image and build number do sound like they are mismatched. If you can't find the vendor image you need on XDA you can find the matching build on the Google site, download the whole factory image and unzip it and get the vendor image that way.
I believe TWRP 3.0.2-0 was buggy. I'm not familiar with Multi rom and I don't know why they would use that build. You should be using 3.0.2-3 or 3.0.3-0.
I personally wouldn't install a custom ROM before activating the phone. I know a couple people have reported in the past that they were unable to activate their phone on a custom ROM. Hopefully you won't have that issue.

MultiRom support for this device was released when Marshmallow was out. So MR33 is based on the Marshmallow branch and ships with 3.0.2. The developer just isn't ready to release support for Nougat 7.0 and couple that with the issues of TWRP 3.0.2-x. He's actively pushing commits to support Nougat.

Thanks for the input! I actually just got my card and some of the activation seems complete. (I got my voice mails and so on, but no data connection yet.) I didn't have a problem with the Nexus 6 on PureNexus, but we'll have to see how this one plays out. I'm not able to call over WiFi yet.

It might just take a while for the service to go through. Good luck.

Vendor Image Mismatch

[SOLVED; MOD PLS DELETE]
Hello guys,
Well, short story: had an oneplus one, today i woke up with the usb port melted and a very dizzy burnt smoke. The replacement phone i got is a Redmi 2. Since i'm a "pure" Android fan, can not stand with the MIUI.
I used the "Newbie" guide here to unlock bootloader and install twrp(i'm pretty used to it and know the basics).
After that, i installed AOKP 8, it boots correctly and it work, but a message keeps poping up every boot:
"A vendor image mismatch has been detected. Typically this means your vendor image is out of date. Please ensure your vendor image matches LMY47V".
Any help with this? Any fix? Anything that i did not notice?
THANKS!

I think (just think, not sure) it's about the firmware. If you got a Redmi 2, it's probably that it runned KitKat before you flash a custom ROM.
As you didn't mention flashing Lollipop firmware, my suggestion is: If you want to use a ROM that is Lollipop or higher, you need to flash Lollipop firmware before flashing ROM. You can find it in the third post in Lineage thread for Redmi 2.
I say I'm not sure, because I've flashed Lollipop firmware a while ago, but last week when I flashed AOKP, the same message came every boot.
Maybe you can try wiping everything, flash Lollipop firmware and then flash ROM and Gapps.
If that works for you (or not), then you can confirm here and help someone else having that same issue.
Good luck!

What were you coming from? Base version? Were you on nougat moving to Oreo?
Have you updated your firmware?
Use the newest version of TWRP.
Are you encrypted? Decrypted?
If you're on nougat, follow the now relatively up to date guide In my signature.
You'll need to back up first.

Error E3004 when trying to install any ROM on Samsung J5 (2015) SM-500FN

What I have:
I have a Samsung J5 (2015) SM-500FN which ran out of storage and basically hung itself up. There is no data I want to recover, but I want to install either a stock ROM or (preferably) something else like Lineage - I just want to get a usable phone again.
My problem:
I have tried to download *many* stock ROM
s from reputable sources like SamMobile (for this specific phone, but trying different release dates and country codes) but every single one of those ZIPs is corrupt, even when downloading from a different computer.
Flashing with ODIN anyway gives a FAIL result and a device that cannot boot, not even into recovery: It gives a green screen with the text: `An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software.`
Ironically, the Smart Switch software just says this device is not supported. The older Kies3 software lets me enter the exact model# followed by the serial# - but then it says this device is not supported. So neither Samsung software is usable, but I can still use ODIN.
Even with the phone in this broken state, I can install TWRP again. So it is not completely bricked. I boot into TWRP and copy a LineageOS ZIP file to /sdcard, but when I try to install that, the TRWP console says: `E3004: This package is for device j5nlte,j5nltexx; this device is .` Note how it doesn't appear to recognize that this device is indeed the model j5nlte!
Android.SE says that "E3004" means my TWRP is too old, but I use `twrp-3.1.1-1-j5nlte` which is currently the newest version for this phone.
I would also like to try a factory reset, but that requires the stock recovery which won't boot (see step 2 above).
My question: How do I get out of this catch-22?
It seems that if I could just get around that E3004 then I would be fine. But I have found no ways to trick the installer into ignoring that error.

Flash an updated twrp .IMG file which you can extract from the file here j5nlte (TWRP)
Just flash the img in twrp and reboot to recovery
Then with the updated twrp try flashing the rom again

THANK YOU! This did the trick. May I ask: what is the origin of that TRWP image? How could I have found that on my own?

No problem at all, glad all is working for you now. Happens all the time with people having the wrong recovery its no big deal but a lesson learned is always make a backup in twrp before going tinckering around with things or keep a copy of a rom, that you know works, on your SD card.
From the bootleggers pie rom thread.
The Dev of that also builds his own twrp for all j5 2015 models.
he's a really great guy to have supporting our j5 community

lineage 17 on samsung galaxy a20e

there are some instructions how to install twrp or lineage on nnthe samsung galaxy a20e. it took me a while to manage it, for one part because it seems sometime i did not do everything exactly like it was described (old fault of mine...) sometimes i found some explication in another instruction.
this is why i post my experiences, to encourage those who also struggle with problems, don't hesitate, sometimes it only takes a bit longer, but also because some things i still don't understand, maybe somebody can explain me what happened..
naturally, firsty of all i first had to install twrp. so i searched for instructions and found some, including liks to download the twrp.tar for my model. some of them i was able to flash by odin, but when i then restarted the phone it only showed a black screen with some pink in the middle, with some fantasy i could read a slight samsung or samsung a20 in it. this happened when i tried to restart in recovery to flas disable-dm-verity, also when i tried to restart direct to system. with all the attempts i got very experienced in flashin back stock rom...
then i found a working recover after restart to recovery i got my twrp screen and was able to flash the no-dm-verity or magisk.
so next i tried to flash the lineage (unofficial lineage 17.zip) but always got the message invalid zip format. tried to unzip and zip again but no way. so i thought i might get lucky with adb sideload, entered the twrp advanced and clicked adb sideload, the screen told me starting adb sideload but the phone could not be detected by the computer. the computer detected it when switched on or in fastboot, so it seems the sideload did not really start.
so i searched the interenet for roms because i really wanted to get rid of google and a million of apps in the stock that i don't need. i found the links to andyyans gsi and several other zips.
as i was not used to the gsi installation i thought i better stick on what i know and tried to install another zip. but most of the time i got the invalid zip message or the zip is for another phone although i downloaded it for the a20e. but then twrp accepted the crdroid.zip (eureka) i downloaded, i was very happy, after the instalation was finished i restarted the phone and the screen went black, turned off and it seemed not pressing to download, to recovery or to start changed anything. i also tried with pressing vol up, vol down and conecting with computer but also no downloadmode started. so i pressed very long always several buttons and after a while the phone vibrated by pressing long vol down and power, but no screen. after it vibrated sometimes like this i turned to vol up and power, it vibrated again and finally twrp started. although the phopne was fully charged when i started the process, it now had only 8% battery.
so i charged the phone again, flashed the stock rom and twrp to try again to find a solution. at this time i also found an instruction that explained why after flashing twrp the system can't recognize the folders (downloads, music... ) and only gives them combinations of letters and ciffers, i have to decrypt it in twrp, wipe, format data, yes and this problem is solved. i don't know it happens always and who made the instructions to flash twrp thought this is common knowledge but in the first innstructions i read it was not mentioned.
i tried again to flash zips and now got a funny eroor message from twrp, unable to zip, this zip is for a20 but this phone is a a10. i tried another zip, the installation started and in the text i could see that it was for a10... so somehow twrp was sure to live on na a10, how could this be??? i thought maybe the twrp was for the a10 (it was a 3.4.x), so i again downloaded a tar directly from the page of twrp for the a20. but when flashed this twrp (3.5.x) and tried to restart to recovery (or to system) the phone was still in downloadmode and refused the custom rom. i had to flash back to stock, then flash again the twrp3.4 that thought my device is a a10, then i could flash the new twrp3.5 i was sure it was from the original site and for my device. i don't know the 3.4 was patched, i got the downloadlink from one how-to-site, but i did not read anything that it was patched...
but after testing all the zips that did not work, and also with the new twrp i was not able to sideload i decided it is time to learn how to handle the xz. so i extracted first the lineage 18, installed it by clicking install image (after wiping) but again the phone turned black and i had to press a while to get twrp restarted and the battery again was nearly down.
the same process worked with the lineage 17, so this is what is now innstalled. both where the correct ab versions, i checked before with treble info what version i need.
so, can anybody explain me
-what happened with my battery when the phone turned to apparently death?
-why could twrp think my phone is a a10, would a twrp for a10 work on my phone?
-is it possible that the sideload feature does not work on this phone?
¡¡¡and many thanks to all those who upload roms and instructions so people like me can make their phones a bit more like they want them!!!

The first time I flashed my A20e (SM-A202F) had the same problems with finding the right TWRP. I cannot answer your questions, but I can tell you what I do.
Beforhand: unloock the bootloader. Upgrade to the latest Samsung firmware. Download AndyYan's 18.1 LineageOS GSI arm64_bvS. Thought arm64_bvS-vndklite can work as well, I found that bvS has less bugs.
After installing the Samsung drivers and the adb stuff on a PC with Windows, I install Odin and flash with Odin the attached TWRP (AP), while phone is in Download mode.
I then go to recovery (TWRP) and if the folders and files are encrypted, I format, then yes. I wipe 4 things: dalvik, catche, system and data.
I then move the GSI image file inside the zip (not the zip) by drag and drop on my PC. Then in TWRP I click install, select image, not zip, select system and flash. Then I reboot to system.
I never had any problems with this installation process. The bvS has a bug with the Lineage music app, but simply install a local music app, such as Musicolet or AIMP from the Aurora Store (from F-droid).
On the camera side I haven't seen any app that significantly improves photo quality. My recommendation would be FreeDcam from F-droid. Use it on special occasions, as it tends to heat the phone.
