custom roms keep puttimg me back into fastboot - OnePlus 7 Pro Questions & Answers

So long time android user. I have the tmo variant of the Oneplus7 pro with unlocked bootloader via exploit found. Have twrp installed amd stock rom rooted with magisk. I tried installing the Havoc and the Aosip rom followed directions step by step. Havoc booted to the first gteen splash screen then reboots to fastboot. Aosip gets to the settimg up wifi then reboots to fastboot. I made a backup of the stock rom before installing anything and im able to restore it with twrp and root. I looked in the threads but didn't find anything unless i missed it. Also been sitting on telegram waiting on someone to shed some light.

S7 G930F stuck in a bootloop after attempt to install TWRP

Hi everyone!
I wanted to finally flash a custom ROM on my G930F (vanilla, with the latest official update) and started by installing TWRP (twrp-3.3.1-0-herolte.img.tar) via Odin (3.13.1) following this guide: https://forum.xda-developers.com/galaxy-s7/development/recovery-official-twrp-herolte-t3333770.
Everything was going smoothly until step 9, because after swiping right I tried rebooting before flashing anything (found a thread on Reddit advising to just follow the guide without proceeding with rooting as indicated in the last steps). So now I'm stuck in a bootloop and I have no idea what to do, I can only access Download mode but that's it.
How do I solve this problem?
Step 10 included scenarios for both if you want root, or if you just want to boot successfully
Did you download and flash the dm-verity and force encryption disabler zip as per the step 10?
Repeat steps 6-10 and flash that zip

Thanks for answering!
Yes I figured out, installed TWRP via Odin again and then tried flashing that thing without wiping as shown in the video, but then I got some error messages and the device wouldn't boot up again, telling me I had to do a wipe. So I just went into recovery and did a factory reset.
Now I'd like to flash LineageOS but I'm not so sure anymore since I've had so many problems, and I have a few questions:
Do I need to reinstall TWRP?
Do I need root?
What version of LineageOS should I download?
Is there a guide for flashing LineageOS on the S7?

Do I need to reinstall TWRP?
No TWRP will remain until you remove it or flash stock firmware.
Do I need root?
Not required to flash custom Rom's but useful
What version of LineageOS should I download?
Look at the ROM section and read up on which one you want, there are several different ones and builds so the choice is yours.
Is there a guide for flashing LineageOS on the S7?
There is always a guide contained in the post for the ROM usually at the beginning. The process of flashing Rom's is generally the same no matter what Rom you use.

From OOS 10.0.1 trying to install LOS 16.0 as a beginner and failing completely

I'm trying to install LOS 16.0 but it just won't work. I've tried using the TWRP 3.3.1-16 Q Unofficial by mauronofrio and it works that I can get into TWRP and can flash the rom and GApps, but then after that process once I try to boot into the OS it is just forever stuck in either fastboot or stuck on the bootloader unlocked warning screen. I did realize that I had to use fastboot flash boot twrp*.img because they disabled fastboot boot twrp*.img in the Android 10 update, but then am I supposed to reflash something on that boot partition now? The whole process is very confusing and the instructions from the LineageOS seem to not work at all. Is there anything I can do right now or is it just not possible to install this until TWRP, or OOS, or something I'm not knowledgeable enough to know about updates?
It's because you are using OOS 10.1 as a base (android 10) and you are trying to install Lineage OS 16 (android 9), so it's quite obvious why it isn't working. Try lineage OS 17 instead.

Lineage OS 17 won't work either. The developer intentionally used OOS 9 as base since fastboot boot command doesn't work yet on OOS 10. OP needs to downgrade to OOS 9 first, whichever of the two Lineage OS versions they wish to use.

I tried this. I downgraded to 9.0.9 and still the fastboot boot command is not working. Apparently this has something to do with the bootloader image itself not being downgraded?
I give up now, my temp phone I was using for holding backups for chat data just randomly wiped itself on havocOS and I've just lost years of chats and stuff and it's got me really down right now. They did fix the fastboot boot issue with today's 10.3.0 update but still nothing is working from any tutorial to get this thing to work on lineage, it just won't boot to it and twrp keeps having errors during flashing. This used to be so much easier on my older phones and I've installed this OS on about 5 phones now but OnePlus 6 just doesn't seem to work no matter what. I'm just going to go back to OOS and hope LineageOS 17.0 will get these issues ironed out by the time it releases. Severely disappointing and a waste of 3 days now but oh well
In my opinion, this is the easiest way to downgrade everything to OOS 9, including bootloader https://forum.xda-developers.com/oneplus-6/how-to/op6-collection-unbrick-tools-t3914109
After that, just unlock the bootloader again like usual and follow the LOS16/17 page's install instructions and you should be good to go.
I tried to install Havoc 3.5 while i was on 10 Ob2, unlocked bootloader and installed patched twrp, then rom. Got stuck in fastboot mode. **** hell i messed everything, later i found fastboot recovery rom from xda, flashed it, thank god it saved me. For me, msm tool was not getting connected, got an error like sahara xyz something... Then after refering to multiple xda threads came to know that most of the present 10 custom roms are based on oos android 9. Then again i used downgrade package from community, reverted back to ob 25 oos (pie), then as usual installation process. So if you are interested in custom roms, downgrade to pie. And again i wanted to go back to complete stock from havoc but unfortunately msm was not responding and fastboot roms wont support upgradation (im not sure), i went to twrp and installed stable 9.0.9 to both partitions + twrp installer. Then 10 oos stable to both partitions + twrp. Then booted up and installed Ob2 again from system updater, lost twrp on that process, then locked bootloader, so mow completely stock ? lot of work for nothing ? oos is better for me.. infact i got used to that. maybe i should purchase another phone to continue the momentum of getting latest updates. crazy oos influence ?

Really confused on steps to root / custom rom.. Help me please

I have the GM1910 version of the OnePlus 7 Pro
Ok so I had a stock OOS 10.3 on the 7 Pro I just bought used, went home and was super excited to get a custom rom installed. From my previous experience back in the day, I knew to USB Debug, OEM unlock, Advanced Reboot for convenience and followed the Havoc Custom ROm guide that said to:
1. Download the ROM, TWRP Installer, GApps, Magisk.
2. Wipe Data, Dalvik.
3. Flash the ROM, TWRP Installer (Use Unofficial Q compatible version, starting at 3.3.1.575).
4. Reboot to Recovery.
5. Flash the ROM, TWRP Installer again.
6. Reboot to Recovery.
7. Flash GApps (Optional), Magisk (Optiona).
8. Reboot and Enjoy.
Never Wipe System or Vendor partition.
After doing so, I first ran into an issue with Fastboot Mode being indefinitely stuck, but fixed that with a TWRP 3.3.1-75 version I downloaded, and was able to boot TWRP. After that, and following the guide above, I noticed it was stuck on the Havoc boot animation. I waited a good 20 minutes before realizing its likely never going to boot. I rebooted twice after that, waiting 10 more minutes each for a total of about an hour, thinking "Hey maybe it takes time". Nothing. I then tried flashing NikGapps for Android Q compatibility as latest Gapps on the OpenGapps website allows up to Android 9. I realized afterward that it was a n00b mistake so I downloaded and flashed the Beta Android 10 Beta Pico OpenGapps and Magisk Canary that also failed.
After that, I started searching around for finding a way to return to stock Android 9 to start over, thinking Android 9 had more stable support, so I downloaded and fastboot flashed the Android 9.5..11 GM21AA - Direct Download, but while showing the OnePlus stock boot animation, it freezes and then the device turns off entirely.
I'm currently waiting for the 9.5.13 Repack (taken from the Collection of Unbrick Tools thread) to finish downloading to see if I can use MSM tool to restore stock Android 9 and kind of start over. I would prefer to root / custom rom Android 9. I have no clue what I'm doing now, but honestly recall it being so easy back in the day before this A/B partition stuff and I would have considered myself to be not so much a n00b, but at least quite "experienced" but I guess thats completely irrelevant now hey!. Can someone please guide me on how I can fix this and get a custom rom booting? Thank you very much!
Update: I managed to restore to Android 10 using the Decrypted Oxygen OS 10.3 ZIP from the "Collections of brick tools" linked above, then rooted that stock OOS using the standard guide. I got Havoc Android 9 working prior but ran into tons of bugs so I just decided to stick to stock for now.

Unless there is something specific you need with a custom ROM, I'd stay stock and root.
I have EdXposed installed and can tweak most things.
I really need ad blocking and some basic customization.
I don't need a full ROM to get what I want.

I would have agreed with you yesterday, but I've used the phone for a few days and cannot stand the insanely rounded corners so I tried finding a work around. So far reducing screen height and getting rid of Oxygen OS's software rounded corners is the way to go but stock OOS doesnt give you the option, I'm hoping a custom rom will. Currently in the midst of flashing RR Android 9
Which boot slot are you trying to flash the rom on and have you tried flashing other roms? I know I've tried flashing havoc a few times and no go. I'm using blissrom right now and it works great until I get the rom I'm building and configuring and have data and messaging working lol

Flashing recoveries never work (except for one case)

Hey everyone,
I have an unlocked OP 7 pro.
Lately, I decided to go back to custom roms after a year or so of sticking with rooted stock.
I've tried to flash Pixel Experience & Flamingo OS and while both completed successfully, they won't pass the bootloader.
Then I tried to install crDroid using the script the author has provided and suddenly it does boot to recovery and I was able to flash the rom completely and boot to it.
Has anyone encountered such a case and has a workaround for it?
Thanks

Just wanna to let any future visitors of this thread how I've solved it.
1. I use the msmtool to reflash stock and lock the bootloader on the way. (Here)
2. I installed OTA stock updates.
3. I unlocked the bootloader again
4. Voila, now I was able to flash stuff.
Good luck everyone

My story and a couple of questions

Hi All,
I have a new-to-me Oneplus 7 Pro. I have been trying to get Lineage with MicroG running. Well it has been quite the adventure and I have it to the point where I have Lineage running fine, and go to reflash TWRP and have bricked the phone, which takes a bit of time to get back to the point of having Linage running again. Specifics:
Lineage version: lineage-19.1-20221219-microG-guacamole.zip
TWRP Versions: I have found that twrp-3.6.1_11-0-guacamole.img works since my phone is at Android 11.
My questions are:
Are TWRP versions tied to Android versions?
When I am trying to get the last version of TWRP installed I have tried 2 approaches:
fastboot flash recovery
fastboot flash boot
Neither worked, phone always ends up bricked. I have used:
TWRP-3.5.1-guacamole-Nebrassy-3.img
twrp-3.6.1_11-0-guacamole.img
twrp-3.6.2_11-0-guacamole.img
I also have tried to boot the images 1st using: fastboot boot twrp-3.6.1_11-0-guacamole.img
and that bricks things.
What am I doing wrong?
Thanks

If you look at the official installation page for your phone, you will see that Lineage OS 20 and 19.1 are supported. So you should reinstall Lineage OS 18.1 again, and then follow the steps on this page. Don't bother reinstalling GAPPS until after you upgrade it.
If for whatever reason you don't want an Android version higher than 11, let me know.
I specifically don't want GAPPS or anything remotely Google related. I had tried OS 20 and found that I had a problem installing apps - probably user error, but I don't need the latest and greatest. I am currently at Android 11.
I will read through the instructions, although the number of tutorials I have gone through is craze.
Can you tell me what the relationship between TWRP and Android version is, and are you able to sus out what I did wrong with my efforts to get TWRP loaded over the lineage 19 version I was using?
Thanks

So I guess you don't want GAPPS, just MicroG. Definitely read through the instructions I gave you, as they are the official installation and upgrade instructions.
I would recommend installing Lineage OS 20, because it is the version that is being maintained right now.
I will attempt to guide you through the steps, but I need to know what your situation is right now: Is your bootloader unlocked? What OS do you have installed right now? What recovery are you using? etc.
I appreciate your help. Currently I am looking at a freshly updated phone with Android 11, and Oxygen 11.0.9.1.GM21AA.
The phone is a GM1917
Bootloader is unlocked and I am in developer mode. I have adb and fastboot loaded on my computer. I also have a working version of msm as I have bricked this thing 6 or 7 times...
Several times now, I have done the following:
Install TWRP
Install Lineage
Try and reflash TWRP <-- consistently fails at this point, gets stuck in a boot loop in the bootloader screen
Thanks

"Try and reflash TWRP" what do you mean, update the OS over TWRP?
I mean trying to re-install TWRP after installing Lineage

OK. Can you try following the installation instructions and skip the unlock bootloader step? Do so at your own risk, because the steps say you have to be on Android 12 first. If you do follow them, just make sure you follow them very carefully.

To my knowledge the guides that are provided on the TWRP site don't work for Android 12 and 13. From what I've heard, you have to root your phone and then install TWRP through Magisk.

Yeah, but I was just saying how they should probably reflash TWRP instead of how TWRP's site says to, which doesn't work

I know, but TWRP can be installed with Android 13 custom roms according to the TWRP thread.
