guys question regarding flashing custom roms/oos ?

id like to know if it is possible to flash OOS without needing to wipe the internal SD somehow?
i always flash custom roms to another custom rom without needing to wipe internal sd and thats rly cool.
but whenever i flash oos i use those fastboot zips and it wipes my internal SD.
is there some way to get OOS to boot up when i am on a custom rom ?
so question is , can i flash stock OOS while i am on a custom rom without wiping my internal sd.
if yes please guide me how to do it !
edit : So e.g i have this flashable zip of the latest oos "OnePlus6Oxygen_22_OTA_015_all_1808102118_770880.zip" can i somehow flash it within twrp and get it to boot up without wiping my internal sd ?
i had tried it before and i just couldnt get it to boot up.

It is best practise to wipe your data if your coming from another rom Otherwise you will get some error.

You can flash the full ROM in TWRP. The full steps are to flash full ROM zip, flash TWRP zip, reboot recovery, flash magisk, reboot. Data stays in tact. SD stays in tact. There is absolutely no reason to wipe sdcard and anyone who tells you is full of crap. The only reason to wipe sdcard is to decrypt your device.

Also, stop using fastboot ROMs. It will wipe your data. It is meant for an emergency recovey, not for regular flashing.

thank you so much man, i initially had no idea ..
i thought for OOS stock roms id always need to wipe sd as it is a A/B device
thats why i often stayed away from oos.
but hot damn oos pie beta is so snappy and smooth..
same goes for Oreo oos stock what i find lots better is the speed /smoothness it blows custom roms out of the water..
and i even noticed that the FP sensor works a lot faster on oos.. in custom roms fp feels slow to unlock phone.
whereas on oos its instant.
i only wish stock oos had FLING.... the only reason i use custom roms at times is the usage of Fling..

The a/b makes ota updates easier. While booted in system a, an OTA will flash to b while the OS is still running and after a reboot, it will boot to b, and vice versa. The reason for a reboot recovery after flashing stock oos zip and TWRP zip is to get TWRP to flash on the correct slot. You can change it manually in TWRP, but that method requires you to keep track of your slot. A simple reboot of recovery will put it on the correct slot to flash magisk. Without flashing magisk, bootloop will happen.

I also forgot! Delete your lock screen before flashing another ROM. That is why your sdcard is inaccessible. If you delete it before going to TWRP, it will automatically decrypt since the password would be technically nothing.

How to perform a clean install?

How to do a clean install(no rom installed just recovery)? I want to format everything and flash my rom thru otg. Shud I wipe everything when I boot to recovery?

I think internal storage is the correct option then though it also removes all media on the device. Otherwise clear system, data, cache, bootloader, dalvik. Then install the rom from external source.

Should I flash from fastboot the recovery(twrp)? It might get wiped once the wipe everything.

I have same doubts....

So do I... You necro'd a 8 month old thread...

I tried to go through few thereds however I was unable to find an answer.
I'm still on 5.11 oreo a d official TWRP. I would like to update to newest pie, however I would go for clean flash.
How should I do it?
I already backed up all app+ data using titanium.
Should I just go to TWRP
1. Factory default
2. Wipe all
3. Wipe system. Data, davlik and cache
4 flash latest pie and don't reboot
5 reboot to twrp
6 flash twrp
7 reboot to TWRP and flash magisk
It it right?
Thank you

Flashing this phone looks like sorcery....
Miss all days we could go to TWRP, erase all **** and then just flash rom. Period.
Now, doing this can even brick the dam phone.
It sucks!
EDIT*
Did Nuke 9.0.5 and install fresh 9.0.3.:angel:

That also happened to me. I do not know how to go to another custom ROM from another custom ROM without going to MsmDownloadToolV4 to unbrick my device. Actually i did unbrick my device twice already because of trying various custom ROM.
Also, is there a way to just restore from recovery then flash another custom ROM. Then if we want to change custom ROM again we can just restore from recovery again then flash another custom ROM?
Please help us guys. Thanks.

Can't install Lineage OS properly; device freezes and reboots after startup

Hi people,
I've been struggling with this for the past 2 days and I'm trying really hard not to give up
I downloaded the stable rom from the MIUI website (for Mi Note 3 aka jason), installed it successfully via MiFlash, and tried flashing Lineage after I did a factory + data + system + cache wipe. It ended with me getting the dreaded error 7.
A bit later, I realized I had to get the dev build from the MIUI website and flash it before flashing Lineage OS. So I did - I updated to MIUI 10 using the dev build, made sure it was working and tried flashing Lineage OS on top of it (after wiping the partitions I mentioned earlier, following the Lineage OS instructions).
So eventually I got it to work - sort of.
Lineage OS is booting properly, but the device freezes before it can find any wifi networks to connect to (and then reboots), and that's why I think the culprit is the modem.
So, a few questions -
1. did it happen to anyone else? I searched endlessly but came up with nothing
2. If it is a modem issue - where can I find a working one? I looked it up and found nothing
3. If it isn't a modem issue - what should I do?
If I'm doing anything wrong - please tell me. I'm flashing custom roms since 2011 and this is the first time something like this has happened to me.
Thanks for all your help!

Hi, first of all you need an unencrypted phone - Format data in TWRP (3.2.3.1), then wipe system, data, cache, dalvik. Flash the Miui 10 china stable firmware 10.0.2 or 10.0.4, then rom, gapps and reboot.
Good luck, zaqm

Mi Mix 3 bootloop

Good day all,
for some time, i have been using the Mi Mix 3 CN version with Xiaomi.EU weekly Rom and i loved it.
Today, I decided to try install the Unofficial PE Rom witch can be found here (https://treble.andro.plus/pe.html)
I Followed these instructions (https://www.getdroidtips.com/pixel-experience-rom-xiaomi-mi-mix-3/)
For some reason i decided to do a full wipe ie. ;
Dalvik/ART Cache
Data
Internal Storage
Cache
System
I went to install PE ROM and upon completion, i was boot-looping and rebooting into TWRP Recovery 3.2.3-1205 for MIX 3 --by wzsx150.
In a panic, i tried reinstalling the weekly ROM again by doing the same steps above, and behold i am still getting the same problem.
Would someone please help me out here as for this is my only phone and need to get it back up and running.
Thanks in advance.

Going from one rom to another requires you to remove encryption so format data

1. Flash the China dev vendor.img, or the full China Dev ROM, or Xiaomi EU (works ok with PE)
2. Install PE zip
3. Quick Wipe and format 'yes' in twrp
4. Flash Magisk
That's how I do it for all ROMs and GSI and works fine.
You'll get the China dev vendor IMG from the link on post one of the PE thread. You can flash it with twrp.
Always recommend to use the vendor IMG from China Dev instead of EU, especially with the GSI ROMs.

are you on global?
In twrp: factory reset then format data (hit yes to accept).
Reboot phone and reenter twrp.
Connect to computer and transfer xiaomi.eu rom onto root of device (I suspect any would work but I happen to have used 10.2.2.0.PEECNXM_v10-9 which is believe was xiaomi.eu stable release), pixel experience ROM zip and magisk-v17.3mod4mimix3
Flash the xiaomi.eu rom first then without rebooting or any formatting or factory resetting immediately flash the PE ROM zip and then magisk 17.3.
Once those three files are flashed via twrp go to wipe and the factory reset then format data again
this always works for me
thanks to @homer.ali

Works for the Mi Mix 3 coming from MIUI 11 EU

Thank you so much for these instructions. Coming from Global MIUI 11, I tried to figure out how to install PE for the last 2 days and every time I ended up being stuck in a bootloop. So far, I tried to install Resurrection Remix, Lineage OS and Evolution X without success.
Your instructions solved this issue. BTW: the only working version of TWRP for me was twrp-3.2.3-8-perseus-mauronofrio. After flashing this version, I was able to install the latest TWRP.
this always works for me

Do you (or anyone else in this thread) know whether these steps [install order: xiaomi.eu, rom, magisk | then: factory reset + wipe data] work for other custom roms on the Mi Mix 3 as well? >> Short answer: no. Tried it for the above roms. I always end up in TWRP (or bootloop) after flashing either way (the official or the on I 've tried here).

@chromanju did you solve this problem?

If you have TWRP, flash the OOS Stable Zip + TWRP, reboot the recovery, and there flash only OOS.
You will have OOS Stable in both slots, and the second flash will replace the recovery with the one from OnePlus
You may have to Format Data at the middle of the operation (When you reboot the recovery before the second flash). If that's the case, you won't be able to do the second flash, because the OOS zip will be erased !

Not necessarily. If you just flash OOS Stable, and Format the Data after, you will have a perfectly working device, with OOS Stable and OnePlus stock recovery. The storage will just be totally empty (So no Zips left to flash anything else like TWRP or Magisk), but the phone will work, just like when you first bought it ! If you don't want to flash anything more than OOS, then yes just flash the ROM, Format Data, and reboot
A PC would be useful if you want to flash OOS a second time to fill the second slot. But even then, you could do without one :
- Flash OOS
- Format the Data
- Reboot, setup the phone, install apps, ect
- Download the OOS Stable zip that has been erased when you formatted from Chrome on your phone
- Do a "Local upgrade" from the Updater in the settings, and flash 9.0.5 again
- Now you have a totally stock OOS Stable phone, with 9.0.5 on A and B System slots, clean as a baby !
I did this exact procedure myself this moning after being stupid and messing with the encryption, and not having an USB cable near me to use a PC

Bro last question, the local update metod works too?

Just install the rollback zip through the local update and reboot.
Nothing else is required
It'll wipe out your data though.
