Updating custom Roms (Noob question)

I have TWRP on my phone already, and everything is backed up. I am currently using the older Sprint Hybrid-X 4.4.4 version of the Rom found in this post.
I recently got the Samsung Gear VR for the Note 4 from Amazon and I have enjoyed it. Unfortunately, 5.0.1+ is needed for Netflix on the Oculus VR app so I assume it will limit other things staying on 4.4.4.
Long story short, I would like to update to the 5.1.1 version of this Rom in the link above. I'm guessing since I have everything backed up all I need to do is put the Rom on my Micro SD, Wipe everything x3, and flash the new Rom, correct? I know this is a simple question, but I just wanted to double check that I don't have to do anything else before jumping in. Thanks in advance to those who may reply.

Confirm your device is rooted. Clear dalvik and other caches and then flash the zip..

Thank you for your post. My device is rooted, and I will make sure to clear; however, it seems I may need to update TWRP to the latest version for Lollipop support. I am currently on v2.8.1.1 with the latest being 2.8.7.0 of TWRP.
Does this seem necessary, and if so would I be able to flash the latest update within the older version of TWRP or should I just do it via Odin?
Note: I guess TWRP says TWRP Install (Requires TWRP 2.8.4 or higher already installed) but I may be able to update with TWRP app.
Update: For those who do want to flash a lollipop ROM you need to upgrade your TWRP if on an older revision below 2.8.4 I believe. I used the TWRP app on google play store. Easy as pie, but you will need your phone to be rooted + have an unlocked bootloader.
- Download TWRP Manager from Google Play Store
- Select Install TWRP from Menu
- Select Your exact phone (make sure you've got this right or you could soft brick your device make/model) as well as latest TWRP version (may need to install at least TWRP v2.7 first via Odin)
- Hit install and on reboot Wipe Dalvik Cache + Cache then reboot system and wait for the update to finish.
Now that I've got that updated I believe I can install the new Rom, I will update my post when I do so if all goes well.

Upgrading from CM 12.1 to 14.1

Hi, running OnePlus One rooted with CM 12.1 and I have a question about upgrading it to CM 14.1 https://forum.xda-developers.com/oneplus-one/orig-development/official-cyanogenmod-14-1-oneplus-one-t3501278.
Do i need to first upgrade it to CM 13.1? Or, can I go directly from 12.1 > 14.1?
If the latter is possible, do I follow the instructions in the thread quoted or do I need additional steps?
thanks

Hi ,you can directly go to 14.1 but now isn't CM but LAOS , you only need to wipe data , system , dalvik except otg & internal and you should go install firmware , not sure cm12.1 one will go on 14.1 and flash rom + gapps + addons ( if you want )

If you want root you should only follow this : https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
after ending rebooting your device redo your things with setup wizard … reboot recovery and follow the guide

OB10 to custom roms

Hi there, can someone enlighten me how yo flash custom roms?my device already unlocked bootloader and i know how to flash cuz i play with xiaomi mi5, sams galaxy3 , sony x8.
For now i dont have a twrp. Im going twrp by fastboot before this.
Im really sure that i already go through all of the post. But seems from OB10 is really complicated.
1.ready fastboot twrp, bluspark twrp,roms, gapps and magisk( if necessary) and custom kernel
2.fastboot twrp by cmd or else
3.wipe what here? Or just factory reset and leave internal storage?
*Here i confused, do i need to wipe for both slot. Im still new to a/b partition. And do i need to do that for both slot to flash as steps 4-10 as below?
4.flash roms then bluspark twrp
5.reboot to recovery
6.flash gapps,magisk? Then twrp back?
7.reboot to twrp
8.flash custom kernel then twrp again?
9.reboot system
10. End right?
Please help me here. I cant find the real and proper steps. The only way i found is from OB7 to custom roms as they share same security patch.
Thanks for any help.

1. Flash any strock rom.zip partition A.
2. After that recovery.zip
3. Reboot back to recovery
4. Confirm you are in another slot B
5. Flash stock rom.zip. Which slot first is not important.
6. After that flash recovery.zip and then reboot.
After that you can install whatever you want.
That what I do if im switching roms and trying new stuff.
Working everytime.
Until OB7 and stable 9.0.2 I used fasboot roms, flashed via AIO tool, but new fastboot roms working different and I got laggy video and audio.

Okeh thats clear for both slot. But for OB10 to any customs rom is it needed to flash OB7?
What do you mean by stock rom?bete rom or stable rom?

Stock any offical rom for OP6
9.0.2 or 9.0.3 or any OB3,4,5,6,7,8,9,10
If you want custom rom, look instructions, there is mentioned what is base rom. That you need flash.
If there is custom rom based OB7 then you need flash OB7(probably working lower builds also)

Thank brotha. I think they need to state which firmware do we need to start from. Otherwise it will be like me that confusing as they will patch up more and more security.

Pie ROM, pie firmware. (Except pre release betas)
Oreo ROM, Oreo firmware.
ROM - always flash latest firmware of the OS you want pie or Oreo (I always go for latest and don't have any issues . Tho I'm back to oos ,debloated now.)
Twrp - Always after ROMs, before roboot.
Gapps - after twrp and reboot, to make sure it installs to the right slot, that's why you install twrp and then reboot.. this will change your slot from A to B or from B to A. Manual switch is never necessary
Flashing gapps flashes to the slot you are in right now, so flashing before the first reboot (after twrp flash) Will get it to the wrong slot.
Magisk - if you want root. After all.
After all this you can, if you want, flash decrypt ..if you don't need your device to be encrypted,this Will give you more to think of tho.. let's just not go into this now.

i understand the process, but get confused at which file to specifically flash twice when they say
"latest firmware of the OS". So lets say the custom ROM i want to flash needs a PIE firmware 9.0.2 or higher,
what file am i supposed to flash?
9.0.2-PIE-OnePlus6Oxygen_22_OTA_027_all_1810260000_d46787d2c9-FASTBOOT.zip
or
OnePlus6Oxygen_22_OTA_027_all_1810260000_d46787d2c9.zip

[GUIDE][FLASHABLE][H990] Downgrade Firmware [Oreo 8.0] to [Nougat 7.0] and back

About
**********
I created this to make it easier for users of the H990 (single SIM) variant to downgrade to Nougat from Oreo.
This is untested on any other variant. If anyone does brave the unknown, please let me know the outcome.
This is particularly helpful when using LOS 16 with working fingerprint sensor,
as previously we needed to KDZ to Nougat and then reroot. This is not the case anymore.
How
**********
This is a tricky process, so I cannot stress this enough: BACKUP EVERYTHING. Your ROM, your pictures, files, Whatsapps, Internal storage etc.
1 - The Downgrade
Do not reboot out of Recovery at all during this process.
Put all these files on a USB OTG or External SD Card.
1. Reboot to Recovery
2. Install the "old" TWRP 3.0.2.1 (for some reason only this version wipes data correctly)
3. Reboot to recovery
4. (This will delete all of your data) Format Data (type "yes")
5. Wipe Data, Cache, Dalvik and System
6. Flash the downgrade zip
7. Flash SuperRom 4.1. Do not choose a kernel in AROMA. Do not reboot in AROMA.
8. Flash MK2000 BTTF Nougat kernel
9. Flash Magisk
10. Reboot
2 - Going to LOS 16
1. Reboot to Recovery.
2. Flash the latest TWRP
3. Reboot to recovery
4. Wipe Data, Cache, Dalvik and System
5. Flash LOS 15.1
6. Reboot
7. Check camera and rotation work
8. Reboot to Recovery
9. Flash LOS 16
10. Flash Gamma Kernel (if desired)
11. Flash GApps Pie (9.0) Nano
12. Flash Magisk
13. Reboot
3 - Going back to Stock oreo
Do not reboot out of Recovery at all during this process.
Put all these files on a USB OTG or External SD Card.
1. Reboot to Recovery
2. Install the "old" TWRP 3.0.2.1 (for some reason only this version wipes data correctly)
3. Reboot to recovery
4. (This will delete all of your data) Format Data (type "yes")
5. Wipe Data, Cache, Dalvik and System
6. Flash my Rooted Stock H990 Oreo ROM (this restores all Oreo partitions)
7. Flash MK2000 Oreo kernel
8. Flash Magisk
9. Reboot
10. (Optional) You can now flash the latest TWRP again and restore an Oreo ROM backup.

Hi JL
You have kindly help me rooting my phone ( I posted in Q&A and you gave me helpful answers. I have the DS version, and I am now now rooted with the 10B ame version. I would be tempted to install this, which seems straightforward. I will probably loose the dual sim, right? Anything I can do. I think I should backup EFS and modem,, and re-install them, right? (BTW, I am looking for how to back up these - the method I found doesn't seem to work with Magisk)

Sure, I can try help
My first question though, is what the aim is? If you are on Nougat, and you want to go to LOS, then you don't need this.
This is mainly to go from stock Oreo to Nougat again (or Nougat again, then to LOS).

Thank you very much for responding.
I am going for stock oreo, just trying to recognise what I need to be aware of before upgrading. Can I just install this or alternatively the oreo AME in this track?
https://forum.xda-developers.com/v20/development/rom-h990ds-20a-ame-flashable-t3883897
Will I run into any problems about oreo partitions/ modem or is it simply to install this or alternatively yours?
Another q. - you use the old twrp, there is quite a lot about encryption in the twrp track, and the fhashable 20a ame I just linked to insists on the newest TWRP. j

thanks so much great guide

Hello bro, can you make one for 990DS or this can also be used for the same without any problem? All I want is to make fingerprint sensor to work with Oreo rooted. Please suggest how to go about it.

yes, I am asking the same question. is it working for H990DS? if not, could u make one for us?
thanks

Probably encrypted device TWRP files with weird file names - Android 12

Since oneplus 6 nas no security updates i decide to install custom ROM LineageOS 19.1 the newest build from official website.
Before installing this ROM i do all steps gently from Funky Wizard guide.
I have ADB drivers, unlock bootloader, installed magisk (rootet phone) backup my OOS and EFS, and installed twrp.
All basic stuff. Now i was ready to go to installed lineageOS.
I install lineage and i do all steps by their official website but with twrp. ( only what i dont flash copy partition zip file i wasnt sure if that will be work with twrp ).
After restart to recovery i must install gapps. Unfortunely the recovery was replaced i was assumed istead of twrp.
I installed gapps with their recovery and all work fine until i want to replace to twrp.
Now when i boot temporarly from img to install it perm. I have weird folder names wihtout any possibility to add ZIP file.
With some research i guess that folders are somehow encrypted.
Could you help me to install twrp with lineageOS when i have still access to this files? I need it for ex. recovery to stock if something in future goes wrong.
And i am currently on android 12 for sure.
Thank you from feedback!

first of all, you'd be better of if you posted this in the right area ==> https://forum.xda-developers.com/t/rom-official-enchilada-12-lineageos-19.4437321/ ==> more chance to get help related to LOS 19 questions (it's pure chance I saw your post here)
second: make sure to follow the instructions given at the LOS instructions pages ==> https://wiki.lineageos.org/devices/enchilada/
Mostly it is important that you have latest OOS 11 firmware installed in both slots before you start with LOS.
For the first steps never mind which recovery you have, just follow the instructions using LOS recovery. Reason is that TWRP is having problems wiping data / performing factory reset, at least it never worked for me. Then later on you can switch to TWRP
Back in May this year I wrote an instruction set here: https://forum.xda-developers.com/t/rom-official-enchilada-12-lineageos-19.4437321/post-86879331
Interesting for you right now is everything below 1.x
2.x is a separate instructiopn set for OTA updates coming later on
Good luck!

Thank you for response. You have right its better to install it directly from dedicated recovery (lineage) and than replace with twrp. Also i fill missing steps (install recovery again and flash parition integration file) and also wipe all data as instruction says. Now after reinstall lineageos and then install twrp i have all normal structure files as before. Thanks again
