Unable to install custom ROM on Pixel after downgrading from O DP2 tp 7.1.2 - Google Pixel Questions & Answers

Happens in this order:
Flashed May full image to both a, and b slots
Fully booted into stock 7.1.2
reboot to bootloader
boot twrp RC1
flash twrp RC2
flash BootSigner - successful
reboot recovery to RC2
wipe cache, system and data
flash Resurrection Remix 7.1.2
flash twrp RC2
flash BootSigner - boot was already signed (also gave warning that there was no functional framework on active slot (active slot is b))
boot to system
White google boot then reboot
White google boot then ram dump
and loop

I was having issues with installing custom ROMs as well. I finally got it to work by not flashing twrp at all between flashing rom, bootsigner, SuperSU, etc. It was kind of a pain because I had to boot twrp from fastboot Everytime but I am now running a custom ROM and kernel.
Once I had everything installed I did finally flash twrp RC1, and everything is working.
I seemed to have issues with twrp RC2. Maybe I was doing something wrong though...

What did you wipe after TWRP booting from stock? (Cache, System, Data?)

I just did the wipe without changing any settings. I believe that includes cache, system, and data.

A default wipe is just cache i think

I was able to update to the June build with no issue from the full image without losing data and was able to keep TWRP, install ElementalX, and Magisk with no issues. Followed https://forum.xda-developers.com/pixel-xl/how-to/guide-stock-7-1-2-root-safetynet-ok-t3617347 (just replacing XL files with non-xl equiv)

Nexus 5 bricked while theming

I've done ****ed up,
i found some free time to update my cataclysm rom from 5.0 to the latest 5.1 version.
ive finished everything and all was good, but i wanted to theme it before my gf arrives.
now i've searched for a cataclysm black theme and flashed one that said it is for stock & cataclysm.
now when my phone boots up it shows the boot animation and then it shows only black screen.
i haven't made a backup nor do I have the cataclysm rom on my phone cuz I dumbass deleted it imediately after installing it.
any ideas how to dirty flash the rom witout booting up the phone? adb?
Can you boot into recovery. If do, if you have twrp, just copy the rom from your pc to the device and dirty flash the rom. Latest twrp supports mtp.

Wipe data, cache and dalvik cache from TWRP. The rom should boot.

phone boots into bootloader mode, even with a fresh rom flash??

Hi. i need some help.
I have a huge problem regarding getting my one plus 6 back up and running.
Here is what i did.
Downloaded a rom, gapps and magisk.
wipe in twrp, install, rom, gapps. worked fine, booted up rom.
when i flashed the lastest version of magisk, it boots into bootloader.
Then i did a DATA wipe. start a fresh boot.
*booted twrp via adb.
* pushed, rom, gapps, twrp into sdcard.
* installed, rom, twrp, gapps. reboot.
goes directly into boot loader.
WHAT DO I DO? my phone is screwed.
EDIT: Room bug. nothing wrong with phone or recovery. just bug in the rom.

Save everything from SD card to PC and try with:
fastboot -w
Then just try installing ROM
And rebooting to it.
Worry about gapps etc after,.
Possibly bad download too
Did you try booting into the other partition. A/B?
Use magisk 16.4 and then you can update thro the app. 16.7 has a flash bug
From seeing him in another thread I think he got it

when a wipe does not get it working, then ( sadly ) go to the next step of "format data", but "BACKUP" stuff you want to keep ( ie. /storage/emulated/0/Download ) to pc first . . .
( it's what I had to do )
Same issue here...
Tried to fromat data but still boot into fastboot.
Rom: Havoc

Had the same problem, boot to temporary TWRP with the fastboot command "fastboot boot <twrp img>", wipe /system and then try flashing stock ROM via fastboot, it worked for me, hope it helps. Good luck! :good:

Problem booting TWRP recovery (Crash Dump Mode)

I has a pretty big problem of that Crash Dump screen some hours ago and i still can't get to fix it. Here is the story, after trying Havoc 2.0 rom i decided to go back to stock so in TWRP i erased the system, cache (dalvik cache and cache), data and internal storage (i wiped internal storage because TWRP just couldn't decrypt it even though the passwd was correct), after that i flashed the stock OOS rom and the TWRP installer (all these being booted on twrp), but when i rebooted into recovery the twrp splash screen just froze there, so i tried to boot twrp through fastboot, but then the crash dump screen apeared, this post: https://forum.xda-developers.com/oneplus-6/how-to/tool-msmdownloadtool-v4-0-international-t3798892 said this was a way to recover from that problem so i tried it, it worked as far as booting into OOS is concerned, but when i try to boot into twrp through fastboot the crash dump screen keeps showing up.
Any ideas?

It worked!
Now i'm installing all my mods again.
Thanks!
UPDATE:
Nevermind, it boots into twrp, but it wont boot OOS, i already tried erasing all the partitions (system, data and cache) and installing OOS and bluspark TWRP.
It turns on, shows the bootloader unlocked screen and then it reboots back to twrp.
UPDATE 2:
Fixed it by erasing all data on oneplus recovery, thanks again, my phone is back from the death (a quite unrooted one).

What's New(?) procedure to install Custom ROMs coming from OOS 9.0.5?

Hello guys,
I'm having trouble trying to install a Custom ROM (Tresk Mod, but I get it with others too)
So basically some days ago my whole Internal Storage got encrypted so I had to a full wipe.
From there I decided to use Msmtools just in case, so I got back to OOS 5.1.5 from there I updated to OOS 9.0.5 via OTA and unlock the bootloader and install TWRP everything works fine.
But when I tried to install any custom ROM I either cannot boot and just boots to Bootloader (Not even the recovery works) and I get "Failed to load/authenticate boot image: Load Error" which I can fix fastboot flashing all the partitions...
Or I straight get a black screen with the White Notifications LED whenever I try to boot either to system or recovery and from there I can only recover using Msmtools...
So I'm now asking, what are the steps for flashing Custom ROMs now?? Because seems like I'm doing something wrong since I'm ending having a Bricked device...
try to flash rom with bluespark recovery
Nothing changed that I'm aware of, but I found that I'll have the same experience if I try to root before booting the system at least once rootless first. Also, I have issues like that whenever I keep TWRP (even Blu Spark) installed. Now I only use it via sideload every time. I never have issues anymore.

I did the following:
1. Upgraded from 5.1.5 to 9.0.5 (Since I was coming from Msmtools fix)
2. Unlock bootloader
3. Reboot to system and then boot again to bootloader for doing (fastboot boot TWRP.xxx.img)
4. Once in the recovery flash recovery and Magisk (just because) and back to system (where everything was working perfectly)
5. Rebooted to recovery and did the following:
Factory Reset (The one that you slide which should wipe Cache, Dalvik and Data)
Flashed the ROM (HavocOS 2.5) and right after that TWRP
And at this point I tried to reboot back to recovery but black screen and cannot boot to recovery nor system not even via fastboot
Is your order different? Am I missing something?

You have to install twrp.zip again after havoc, boot Back Into Recovery and then gapps and magisk

Agreed. Always reboot from recovery to recovery after flashing a new one (TWRP). THEN, go ahead and flash gapps and magisk.

I finally figured it out
The problem was that as I was updating via OTA OOS 9.0.5 was only installed in one Slot so I need to install it in the other as well.
Did the following process:
1. Boot to Bootloader and do "fastboot boot TWRP.img"
2. From there flash TWRP.zip and Reboot back to it (Recovery)
3. Flash OOS Latest (9.0.5)
4. Flash TWRP
5. Reboot to TWRP
6. Flash OOS Latest (9.0.5)
7. Flash TWRP
8. Reboot to TWRP
9. Wipe data, dalvik cache
10. Flash ROM
11. Flash TWRP
12. Reboot to TWRP
13. Flash gapps + Misc (Magisk, etc)
14. Boot system
Technically just one 1 installation should do as the other slot was already populated but the twice just to be safe.

Android 10 & Custom ROM & Slot A + B

Hello Android developers and enthusiasts,
I've been installing ROM since 2011 so I would not call myself a n00b however I seemingly cannot install an Android 10 ROM without issues. So this is a plea for help and advice!
I know you need to have OOS installed before you install a custom ROM so I use Auto Flash ROM to install OOS with Android 9 via System Update. I then boot and set up phone, install update, reboot and then install the OOS android 10 via the System Update. I then have a OOS installed with Android 10.
Why would I use such an elaborate method you may ask? Well, I tried to download latest OOS from OnePlus site and wipe phone and then install OOS but that fails (didn't record the error I'm afraid).
I then download all the ROM + dependencies on an USB stick and use fastboot to flash Mauronofrio TWRP. I then follow the steps in the ROM instructions. For EvolutionX these were:
First Time Install / Clean Flash
- Have OOS 10.3 flashed to both slots!!
- Boot to recovery
- Flash BUILD.zip (TWRP built-in)
- Wipe Cache
- Format data
- Reboot to recovery (optional)
- Flash Magisk.zip (optional)
- Reboot to system & #KeepEvolving
Click to expand...
Click to collapse
I followed these to the letter but when i rebooted system I got a snapdragon error and it wouldn't even boot into TWRP until I used fastboot to flash boot into TWRP. I also tried HavocROM and same happened.
I did manage to install Syberia using above method but I didn't like the ROM that much unfortunately.
Finally, I've also read up a lot on Slot A and B but it still is not very clear to me. I think I understand it but what happens does not confirm my theories
I therefore have some questions:
- Should I be able to wipe my phone and install OOS on a wiped phone and then install a custom ROM?
- When I install ROM and it says "Reboot Recovery" and then install ROM again. But if I check what slot is being used the reboot doesn't seem to change the slot. My assumption was that booting recovery was to install ROM in the other slot. Is that correct?
Any other tips you can give me?
Again, I like to stress I am not new to installing custom ROMs so I am a bit disappointed that this is causing me such grief.
Following some answers I will retry tomorrow so I can give some more details if needed. For now, appreciate any help.

Hi!
I had this exact same problem a couple months ago. Rebooting to recovery used to change slots for me, but then it stopped.
What you can do is change active slot manually on Reboot section. By doing this, you don't even have to reboot to recovery in other to flash the other slot (altough I do it just to be safe).
And remember: the rom is flashed on the inactive slot, so after the final flash you gotta change slots one more time.
When you flash one ROM on top of another different ROM, particularly OOS to custom, always wipe data and not format data, because some custom ROMs do not support being unencrypted in the first time and then encrypt on the first boot. So do it like this:
Flash OOS
Flash TWRP
Reboot recovery
Flash OOS
Flash TWRP
Reboot system
Complete initial setup
Reboot to recovery
Wipe (not format) data
Flash custom ROM (start here for dirty flashing ROM update)
Flash TWRP
Reboot recovery
Flash custom ROM
Flash TWRP
Reboot recovery
Flash Magisk
Reboot system
I don't like built-in TWRP in custom ROMs. I always use @mauronofrio's TWRP. So regardless if the custom ROM I'm using has TWRP built-in or not, I always use the method above. I didn't have a problem with installing ROMs using his TWRP. Slots always switch when flashing ROM.
Thanks for the info, it really helps.
One question: in your experience can you wipe your phone and then installl OOS on the wiped phone?
So I just booted into TWRP, did standard wipe action: Data, Cache, and Dalvik. I then try to flash the latest OOS zip and I then get this error:
Error applying update: 7 (ErrorCode::kInstallDeviceOpenError)
Updater process ended withL ERROR: 1.
Error installing zip file: '/usbstorage/00, INSTALL/OnePlus6Oxygen_22_OTA_044_all_2002220042_a46425f1bfe43d2.zip
FIXED: I was using TWRP 3.3.1.11 and I then found out there was a newer version: 3.3.1.18 which you can get here: https://sourceforge.net/projects/mauronofrio-twrp/files/Enchilada/
I am now able to install OOS from scratch (ie wiped phone).

I tried this method and everytime I can't seem to flash oos onto the other slot because when it reboots to recovery the folder is encrypted so I can't see which file is the zip. How do I flash the seccond OOS if it shows up encrypted in TWRP.
I have a OnePLus 6 with the latest OOS now because I got into boot loop and i used a flash-all.bat to get back to stock. I also use maronofrio's twrp because that works.

If you can boot OOS fine, try to do a local update so that both slots have OOS. Then try to flash a custom ROM again using the method I've mentioned.

When you say local update you mean while I am running the rom, go to settings then do update from local source?

@Cypher_01, Try this guide. This worked for me. I did not reinstall Nikgapps. Maybe that's where the problem lies? Don't forget to change the update slot at the end before you restart.​
