Hello everybody,
I bought a Oneplus 7 Pro a few days ago and I'm preparing it for my daily usage. It's my fourth Android smartphone, and the third Oneplus. So far, I managed to flash everyone of them, with no major issues.
And then, the Oneplus 7 Pro suddenly appeared
I used this tutorial to unlock the bootloader and flash the custom recovery.
From my understanding, the custom recovery is flashed in the Recovery Ramdisk and available for both A & B slots.
For now, I have A and B slots with stock OSS, unlocked bootloader, custom recovery and Magisk. All of this is working.
There began my problems. I want to flash a custom ROM without Gapps and I fail to do it. All instructions around ROM threads seems different to me, I don't get the thing about A & B slots, when I flash one rom, it boots as usual on the stock ROM, if I flash both slots, It causes bootloops and if I manage to launch the recovery, my internal storage isn't detected and I can't restore any backup.
I already used MSMDownload to restore the phone completely once.
Can somebody explain to my dumb person how to do it proprely ? Thanks in advance ! :fingers-crossed:
TL;DR : I fail to flash a custom ROM and make it work.
Yes I had same issues when rooted, it means you lost root. You can try tool all in one to flash recovery and magesik via fastboot. If that doesn't restore your access, on twrp you will have to type in format, then mount, then add rom to storage(this method wipes everything beware)

For now, my phone is working nicely. But that's the process of flashing a new ROM that fails. Recovery and Magisk are already and working.
Factory reset
Flash rom
Flash twrp installer
Reboot recovery
Format data
Reboot system
i boot all roms with these steps

Thanks, I will try.
When you flash the ROM, does TWRP tell you that if you want to continue you need to reboot recovery ? If so, do you ? Do you reboot recovery on the same slot, or do you flash both ?

Nope, it doesnt tell you anything. Just reboot recovery from reboot menu. Don't touch the slot options
Thanks for your advices.
I'm trying right now, here's my steps :
- Wipe Data, Cache, Dalvik Cache (the standard Factory Reset)
- Install ROM : TWRP logs show that he's flashing on inactive slot A, then B. After that logs said " To flash additional zips, please reboot recovery to switch to the updated slot ". I'm going back on the menu
- Install TWRP Installer like previously
- Reboot Recovery : TWRP ask me if I want to install the TWRP App, I dismiss. After reboot of the recovery, it asks if I want to keep System Read Only, I swipe to allow modifications
- Wipe Data : Can't do it because TWRP is unable to mount storage. And after further investigations, I'm now on slot A, not B as before.
- Reboot recovery to slot B
- Wipe Data on slot B
- Reboot system
And It still booting on the stock Oxygen OS Rom, not the custom one installed before. I'm lost
The problem is that you are not performing factory reset.
Wipe data is not enough,you gotta go to wipe-format data-enter yes and swipe.
That is why you are getting bootloops and twrp unable to mount storage problem.
A/B is pretty simple.
You got two slots for many partitions like system vendor boot and all,but a single data partition.
Flash a rom from one slot,it always gets flashed to the other slot no matter what.So next time you reboot to recovery or system it's gonna be on the other slot.So here is the problem..one rom cannot decrypt data which was initially encrypted by another rom..so you gotta perform a data format instead of wipe.Thats it.

Well yes, I didn't understood the difference between Wipe and Format Data.
So let's resume :
Unlock Bootloader
Advanced -> Install Recovery Ramdisk : Install TWRP
Install -> Flash TWRP Installer
Install -> Flash Magisk
Reboot -> System : Reboot on stock OxygenOS Rooted
Then
Wipe -> Factory Reset : Wipe Data, Cache and Dalvik Cache, that means you just have to swipe on TWRP.
Install -> Flash ROM : Use the install function and install the ROM
Install -> Flash TWRP Installer : Don't reboot, go back and install as the previous step
Reboot -> Recovery : Reboot TWRP and it automatically load the other slot
Wipe -> Format Data : Click and type yes
Reboot -> System : Just reboot and it should load the installed ROM
is wiping internal storage compulsory?

Not wiping.. formatting..that is compulsory if your current data is encrypted
After multiple tries to verify the process :
Wipe -> Factory Reset + : Wipe Data, System, Cache and Dalvik Cache
Install -> Flash ROM : Use the install function and install the ROM
Install -> Flash TWRP Installer : Don't reboot, go back and install as the previous step
Reboot -> Recovery : Reboot TWRP and it automatically load the other slot
Wipe -> Format Data : Click and type yes
Reboot -> System : Just reboot and it should load the installed ROM
Install -> Magisk
Reboot -> System
Install -> Whathever you want
Reboot -> System
It worked !

The very first ROM I tried to flash was a version of CarbonRom. I was unsuccessful, as i got the installation aborted message. I then tried a couple of other lesser know ones, with the same luck. Lastly I tried CM 10.1, and with that, i had success. It was the only one that would work so far. Yesterday, I downloaded DU 4.2.2, and A new nightly version of Carbon (Specifically for my phone) With no luck of installation. Am i doing something wrong with these? Is there a different method of flashing i'm missing?
what is the procedure you take to install?
I usually go this route:
1) Boot into whatever recovery you have
2) Wipe Cache/Davlik
3) Install custom ROM
4) run a factory reset
5) Reboot

I have Philz custom recovery which based on cwm version 6.0.3.7 which when you tap wipe data you will then have the option to clean install for new ROM.

Sorry for not replying earlier, i never got a notification. I'm using the most recent version of CWM. My usual order is :
1. Boot into recovery
2. Factory Reset
3. Clear Cache Partition
4. Wipe Dalvik
5. Format /system
6. Mount /system
7. Flash new ROM

well we now have 3 custom recoveries to choose from I like the newer one since I can install a new ROM in fewer steps.
i would do a factory reset after you flash your rom too, can't hurt.
of course on updating the same ROM, I only Wipe Cache/Davlik and that's it.
Bad download? Does the md5 match?
after making sure you wiped everything make sure the download itself was proper I am running it flawless right now
SuperMan-Rom V1.8.1 Aroma - AP will not boot (integrity verification failed)
On My S7 edge, thought I'd give it another go at trying to root since this rom claims to be almost stock with an option to get rid of all the samsung rubbish (like s-voice) that you don't use ever.
Followed all the steps to root, ON STOCK OS, entered developer mode, allowed OEM, allowed USB debugging, turn off verify installs by USB abd. Now It seems the phone is prepped and ready to go.
Flashed TWRP with latest ODIN 3.11, made a backup of stock OS, back in download mode and flashed required bootloader and modem (BL and CP), boot again into recovery to flash AP (SuperMan-Rom_SM-G93XF_V1.8.1.zip). Went through all the process and it seems fine until 1st boot.
***Every try is showing "Verification Failed, Unable to restart your device. The Integrity verification has failed. You need to reset your device to factory default settings. This will erase all your data."***
Have I Done something wrong to be showing this error every time????
I had the same error message. The cause was that my device was encrypted. TWRP can't handle encryption on the S7 yet. Reboot into TWRP and look at the logs. If it says it couldn't mount /data, then this is probably the same issue I had.
To fix it, I restored the backup OS from TWRP, made a backup of all apps and data to external SD using Titanium Backup and wiped the encrypted partition in TWRP (which removes the encryption and all data). There may be better ways, but this one worked for me.
@Davebnly You need to take backup of the Internal Storage data and then do a wipe using TWRP, Since TWRP cannot handle the Samsung's Encryption the only way to bypass this is by formatting again. This is already mentioned in the Official TWRP Installation post here.
I have this same error after flashing a custom ROM. I did not take a backup of the old stock ROM as it's a new phone and I didn't think I needed to!
Can anyone tell me, if I flash the stock ROM will it let me into the device again?
Is there anyway to wipe the encrypted drive without installing stock ROM?
*UPDATE: I just logged into recovery and did a factory reset and it loaded the custom ROM. Not as lengthy a solution as I expected!

Hi, I'm sorry but what does all that mean? Reboot to recovery??? The only option on my phone is the button to RESET DEVICE and I have two weeks worth of photos and videos that I have not backed up yet! Please help!!! FYI, I have the same exact message telling me to erase all my data because I need to reset my device. Nooo, I am so scared right now.
Hello guys .
This is a guide to flash lineage os 15.1 or any other oreo rom on mi a1 without any fuss, bugs, wiping internal storage. And update it by dirty flashing it. I personally use this method and others have also used resulted in booting safely with zero bugs in the rom, no force closes.
So here you go :-
1- boot to twrp
2- wipe system,cache,data
3- check on which slot you are.
4- if you are on A, change to B (after wiping).
5- boot to bootloader and boot to twrp which I gave.
6- wipe slot B also. (System,cache,data)
7. Don't touch slots and boot to recovery.
8- just flash los15.1 rom from there and nothing else.
9- go to bootloader and again boot to twrp
10- flash gapps and boot to bootloader.
11- again boot to twrp which I gave and flash magisk.
12- reboot.
Enjoy. You have los 15.1 without wiping internal or downgrading to nougat or wiping internal storage.
So now here's the guide to update it. (Dirty flash)
(Remember to remove your pattern, pin, password before flashing or backing up)
1- Backup your data using twrp which I linked down below.
2- boot to twrp which I gave you.
3- wipe system,cache,data
4- check on which slot you are.
5- if you are on A, change to B (after wiping).
6- boot to bootloader and boot to twrp which I gave.
7- wipe slot B also. (System,cache,data)
8- Don't touch slots and boot to recovery which i have
linked down below .
9- just flash los15.1 rom from there and nothing else.
10- go to bootloader and again boot to twrp which I gave.
11- flash gapps and boot to bootloader.
12- again boot to my twrp and flash magisk.
12- reboot. Let it boot completely and skip the setup.
13- boot to twrp i linked down.
14-just restore your data backup and reboot.
Congo you have successfully updated your rom without wiping data and also whosoever is facing bugs like fp not working and other bugs use this method. Everything will surely work.
Anyone who has a problem can message me on telegram. Username- droidreboot

Have a good day.

If you're updating none of your apps or data will get erased. But if you are moving from stock oreo to this rom, it's like resetting your device. That's it. ?

You have ro to wipe data if you are changing roms. Like if you are on lineage, and you wanna install resurrection remix then you'll have to wipe system cache data in both slots. And if developer of lineage pushes an update and you're on lineage then you don't have to wipe data. I mean if updating you have to make a backup then wipe. Then after first boot restore that. Don't do this if you're changing roms. You'll get a bootloop

It says if you're upgrading from stock then wipe data. And if you're updating from old lineage build to new first make a backup then wipe and after first boot restore the backup. Read carefully.

Tried that. not working. Also if its relevent system, vendoe, etc are not mounted. only data, cache, and microsd is mounted. Have no idea why.
Me too faced this kind of issue, peter's TWRP worked for me, follow instructions from here
Ok It worked. No need to flash the dm Verity for orange recovery. What I did was simple.
1. Factory reset (Did this step before also)
2. Format Data (Also Did this step)
3. Flash rom (Of course did this too)
4. Then reboot to RECOVERY again, not to system. (did not do this step before). Go to reboot part and click reboot to recovery, not to system.
5. After that reboot to system and it should work. Mine did.
Solved
I to had same problem but mine worked after installing custom ROM install FCrypt disabler.zip from recovery then reboot and enjoy.
Download FCrypt disabler.zip for Redmi note 7 Pro from Google.
Flash any zip which disables dm verity things. Suggestion: flash lazyflasher zip.

hello mate
and when i install Rom, do i need to install on both slots or i can have one has backup (its what i have been doing till now)?
and when i factory reset, what will i lose?
Well, it is difficult to say. Usually, every ROM has its thread, its instructions and its community that helps with problems related to installing that ROM.
It could be a few things:
1) I do not see any mention about wiping data. Usually you need to wipe data and wipe system partition in twrp before you install a new ROM. Maybe that is the issue. However, what you need to wipe is ROM specific.
2) Check prerequisites, what ROM version you need to be running before you flash. Sometimes that matters.
3) OnePlus 6 has these A/B slots that I do not fully understand. From what I have read, if you are running on slot A, update installs on slot B, and then you reboot to slot B and cycle continues. BUT DO NOT TRUST ME ON THIS. You should read yourself. Anyway, sometimes people recommend flashing both slots A and B. For some ROMs. For LineageOS, for example, that is not necessary.
oh, factory reset damn i would want to configure everything again
I think first.
You have to WIPE data, all. Factory wipe option.
Then boot into twrp
First, flash OOS, followed by TWRP
Reboot to Recovery using twrp itself.
And then again flash OOS and TWRP.
Reboot to recovery again (using the option in twrp itself)
Finally, then install your rom followed by gapps etc etc
Then it should work....
is there anyway to do this without factory reset?
no
