Guide to flashing rom - OnePlus 8 Pro Questions & Answers

used to flash my phones back in the day, seems a bit has changed. If you could point me to a guide, maybe where to start?
I've flashed TWRP on a and b, and trying to figure out how to flash a ROM now.

It depends on how the Dev set up the rom to be installed. Typically if the rom is .zip, you can install it with TWRP. Once you have downloaded your rom, copy it to your phone to a folder so you can find it easily. Reboot to TWRP and hit the Install button. Then navigate to your folder that has the rom in it and click on it. It should go through the install process and when its done, go back to the main TWRP menu and hit WIPE. If you are changing roms, you have to wipe your data or it won't boot up.
Also when you flash a rom, you are also flashing recovery from that rom and wiping out your TWRP install for that slot. You can re-install if you want.
Usually if your installing an after market rom, the dev will give you installation instructions. Most of the time they use Fastboot & ADB for these double slot phones since TWRP has not been available since its inception until lately.

Here's a bit of a explanation..
[GUIDE] The Noob's Guide to A/B Partitions and Other OP6 Idiosyncrasies
If you've just arrived on the phone modding scene, or are coming from another phone that uses traditional approaches to flashing, you've likely come across people talking about the "A/B partitions." If you don't have any experience with this...

Need Help on Manual Recovery Screens Clockwork Mod

Got Rom Premium, CWM, and AmonRa on N1.
Playing and trying to learn about the manual (green) recovery screens.
Q1: What is the Apply Update:Update.Zip for?
Q2: When in those screens, no buttons I try can take me back to previous screen, like vol- does in AmonRa.
Thanks for any help and I read dozens of search results without really understanding Apply Update and no luck on going back on screens.
I am not expert yet, so please keep replies at a for dummy level.
Ken
If your using Clockword Recovery then Ill help ya out.
1: Thats used if you have the rom or update on the root of your sd card and have it named update.zip. This is how we used to flash roms on the old recovery menus on the G1, they just left it in. Now you can just search your sd card for the rom you want.
2: The power buttom will go back, and if your on the main screen the power button will turn off the display to save power.
What do you mean when you say manual recovery screen? Do you mean the stock recovery or are you talking about a custom? With the stock recovery it will only install files named update.zip signed with google keys. If you are talking about a custom recovery that means that it will search for a file named update.zip and flash that.
Thanks a lot,
1. I thought the zip wasn't needed anymore based on my research.
2. Got it, I swore I tried that.
When on main screen how do you exit it?

1: It isn't, they kind of just left it in as a fast way of flashing without having to look for it.
2: Just hit the reboot option at the top.
One more question, at least for now.
Is going back and forth between recoveries, as easy as just "flashing alternate recovery" from that selection. I.E. CWM to AmonRa and vice versa?
Your help is greatly appreciated

Yup. Tho id recommend Clockwork, since im a little bias.
And no prob, I was an android noob at one time.
Ninja Edit:
A warning tho, if you use nandroid, the 2 recoveries don't play nice with each others nandroids.
Thanks McFroger3,
I like what CWM offers just heard some problems with it and AmonRa is rock solid, but more manual and doesn't allow for quick flashes of the CM6 nightlies I am on.

I am just talking about the green screens where you do your backup/restores, flash roms etc. Bad semantics on my part. It's where you go when you select Reboot into Recovery on the CWM main screen.
I think I am good to go,
Thanks,
Ken

Right, I am assuming you are talking about Backup with CWM, restore with CWM and same for AmonRa.

Yea, if you back up with CWM, and try to restore with Amon, you will run into issues lol.
Thanks Again for the heads up,
I read that during my research to solve these issues which you quickly helped me with. I won't mix the two. If CWM works well for me, I will use it most if not all of the time. I got into this helping new rooters on the Nexus One forum when most used 1 click to root and started using Rom Mangager and CWM.
Got to call it a day!
Thanks,

OK,
I want CWM Recovery to work for me. I flashed the latest nightly from the list in ROM Manager. Followed all prompts and allowed the Google Addons to be downloaded also. OK'd backup. The backup and nightly went fined. But, the gapps hung on installing. Had to pull battery, reboot, and restore to previous backup. All Ok now, but it bothers me and not sure if I want to try again. Have been flashing roms, gapps etc with AmomRa for awhile.
Did I miss something? CWM did all the choosing of what to dl and flash. Something different on gapps? It was hdpi-frf91-2-signed.zip. I know that is not the latest. Latest is frf91-UP. Don't know if that matters.
If I have to copy that to sd and flash, what is the procedure? If I select the latest nightly, I have to tell CWM I don't want the gapps, then does it give me that opportunity to grab the gapps zip from sd card before it flashes the nightly. If not, I have no market on phone to dl anything like Titanium to get phone running.
What am I mising?
I copied latest gapps zip to sd card, did not rename. It has .zip on end. Playing around I selected Install Rom from SD Card and found the zip. Clicked on it. Options under Install Queue screen: Ok or Add Zip. Do I zip since it has one. And this allowing me to queue it and go back and add another rom. Didn't see those choices when I did the procedure from the Download Rom choice on Rom manager main screen.
Easier question may be:
If I want to flash latest nightly and a gapps zip I copied to sd card, the latest. What is the procedure?
It seems CWM won't let me install latest nightly without installing gapps, not the latest. Don't know if that is my problem.
Seems I would need to flash latest nightly again and if ok, just flash latest gapps, no wipe, over the just installed nightly.
And if gapps don't install, I can go back and flash my latest gapps from the sd card.
Any thoughts.
Had to flash my latest .zip fromsd card after the gapps attached to lastest nightly failed to install again.

[Q] how to install custom rom over another custom rom on i9500

Hv been using Arrow rom 8.0. Works fine but wanted to upgrade to Arrow rom 9.0 which is based on the rom for India.
The phone is rooted and custom recovery installed(don't know much about the way to use it). Downloaded the rom and went into recovery mode. Ok'd the wipe data/factory reset. Ok'd wipe cache. Ok'd the option of upgrade from external storage and the phone went to the manual mode with csc as inu and asking for the filename. Didn't know what to do so yanked the battery and rebooted. The booted to Arrow rom 8.0 with all data gone.
One more thing I noticed that in recovery mode I had to use a magnifying glass to read the options. Also there was no option to choose the external storage ie the sd card where I download or copy the roms it only shows phone storage.
Would appreciate the help received in pointing me to the right direction.
These are really basic questions. I'm supprised you managed to flash a rom in the first place.
Full wipe in recovery, if you still could boot after wiping, like in your case, then you didn't wipe correctly. Your phone shouldn't be able to boot anymore after the wiping (because there is no more rom installed).
Then flash the rom. If there is no option for external storage (i think this is highly unlikely), then just copy it to your internal sd card and flash from there.
Are you really sure you have a custom recovery? Because the way you are descriping it, it sounds more like the stock recovery.

Thanks for the advice. Checked using recovery tool and it says current firmware: stock.
How do I make a full wipe. And also what about the manual mode I get in the recovery mode.
Can mobile odin be used for flashing.
Again, these are really basic questions. You should read the forum more, my guess is you have a I9500, so start reading in that section. Read the parts about rooting, flashing a custom recovery and flashing.
All the information you need is there. I can tell you the exact steps you need to take, but figuring it out for yourself will save you lots of trouble in the furture if anything goes wrong.
I have no idea what manual mode is, so my guess is that you don't have a custom recovery installed. What is the name of the recovery? Or doesn't it display any name? You shouldn't be needing Mobile Odin, maybe only for rooting or flashing a custom recovery, but not for flashing the rom.

Had read the forum before flashing the rom. Rooted my phone and had installed CWM via Odin and confirmed it in the recovery mode. And only after this flashed the Arrow Rom and used it for couple of months.
Don't know what happened to CWM it wasn't there this time in recovery mode, it showed Android System Recovery and not CWM.
Anyway have flashed CWM again along with Crash Rom 11.
Thanks again bro.

GT-I9505 Constantly restarting

Hi all
Got an I9505 on O2 and since lollipop update it restarted a few times by itself. Now it keeps going into a loop where it will restart and the home screen loads, you can use it for about 20-30 seconds and it will reboot again!
Initially when I researched I though it was an app problem but couldn't find the culprit. Then I took it into the Samsung repair centre and they said it needed a clean flash by them. This didn't work and they fitted a new mother board and this still hasn't worked.
I can say that it has twice happened when the Wifi hasn't been working properly so I have turned it off but other than that I have no idea!
Also I have tried rebooting into safe mode but it still does it, aaarrrggghhhh!!!
Any ideas where I can go from here please?
P
Return to kitkat if you can. Otherwise use a custom rom. These would be my suggestions. Since Samsung's repair couldn't fix it, warranty should not be a problem anymore.
Thanks, I am more than willing to try a Custom ROM. Any recommendations? And how easy is it as never done before!

It's fairly easy. Depending on what S4 model you have. Some models have a locked bootloader and that makes the whole thing trickier.
This is what I did:
1) Root with CF-Auto-Root. Thread here.
2) Backup all my apps.
3) Install a custom recovery (TWRP). Download and instructions here.
4) Flash custom rom. Most roms have their own instructions.
You can skip 1 and 2 if you don't want to backup.
Installing a custom recovery can be done using Odin. I recommend TWRP since it's the only one I've used.
Lollipop GPE rom. I've used this rom and didn't have any issues. CM12 seems a bit faster, but the GPE was more stable and bug-free.
Thanks I tried to install the CM12 before you posted using the instructions there but it failed, I assume that it needs to be rooted.

You need a custom recovery to install any rom. It doesn't matter if it's rooted or not.
Get a custom recovery. Get all the necessary zip files (rom, gapps, etc). Place all the zip files on the external sd card. Boot into the custom recovery. Wipe /data, /cache and /dalvik-cache.
Go to Install (if on TWRP), go to the location where you saved the downloaded rom zip and select it. The swipe the slider to begin flashing. Afterwards flash the gapps zip. Reboot.
Also, don't use the recovery posted in the CM12 thread. It was specially made by the dev and will convert your file system to f2fs. What it basically means is that it will wipe your internal storage completely.

On the CF-Root page it says to open Odin and click on the PDA button but I cannot find a PDA button!

You don't have a custom recovery installed. That is probably the stock recovery. You can't flash a rom using the stock recovery.
You absolutely need a custom recovery if you want to flash a custom rom.
Custom recoveries are: TWRP (Team Win Recovery Project), CWM (ClockworkMod Recovery) and PhilZ Touch Recovery. Either one should work. But you necessarily need one.

Thanks I have installed TWRP, then it asked me to install Busybox which I did. Tried to Install from Zip and it went back to the original recovery and now when I am trying to restart the phone I just get messages telling me things have stopped working (Google play, settings etc etc) and a black screen!
Currently factory resetting and will try again

Follow the link I gave you. They have several instrunctions on how to install TWRP. You can install TWRP with Odin too.
Here, There are 3 ways to install. Use Odin. It doesn't require root and should be the easier one. Just UNTICK auto-reboot in Odin before flashing. Once it's done, turn the phone off and use the key combo to get into TWRP recovery.

I guess that's the CM12 logo. First boot after flashing always takes some time because the rom is configuring stuff.
If you still don't get into android, turn off the device and turn it on again. If you've done everything correctly there is no reason why it shouldn't boot.

No problem. You could try a different build. Or you could try a CM12 based rom. SaberMod worked fine for me. And it's the closest to the actual CM12 you can get.

Cheers, I have CM12 up and running now. Downloaded the files straight to the SD card and they worked. Seems OK but might try others, how do I go about trying SaberMod, do I need to flash that? Sorry to keep asking what are no doubt pretty obvious questions but I'm pretty new to this!
Want to get rid of the google search box for starters!

SaberMod is a rom. SaberMod CM12.1.
They are very similar. The difference is how they tackle optimizations.
Yes, you will have to flash it. But you can also stick with normal CM12 if you don't have any issues.
The google search box from the home screen or the recents?
You can change the launcher to get rid of it from the home screen.
To remove it from the recents there is an option somewhere in the settings.

Linux based restore to stock

New around here and I'll pitch in as able but unfortunately start with a question...
I am running LineagesOS 14.1 now and would like to return to completely stock. I don't run Windows. Could someone point me in the right right direction to a howto that would work using only Linux as the PC OS? There are a plethora of various restore to stock articles on here but some have missing links to software and most involve using Windows, etc.
Thank you in advance.

Use my restore guide if you have an A2017G. If you have an U you could find the flashable files too, but idk.
It's basically: get into TWRP, wipe data, system, cache, dalvik, then flash raystef's bootstack zip, then his stocksystem zip, then the stock recovery img from one of those versions. Then go to the Reboot section and select reboot to recovery, you'll get into the stock one. Select factory reset, and you're done.
You didn't mention it but I guess you wanted to relock? If you do, I think this is enough, but you might want to reinstall TWRP with your PC and follow the "remove unlocked bootloader inscription" guide by raystef, which basically gives you fastboot back. Then flash the stock recovery img again

DrakenFX made the U flashables. And you can get the recovery img from a stock system file, e.g. b32 or b35, just open the zip and you should find a recovery.img, then install it via Install - Install image

Us996 TWRP not sticking

I'm using the tutorial on the LineageOS wiki for the Us996. I've unlocked the bootloader via official means from LG, but when it comes time to send the recovery via fastboot, it successfully sends and writes it, it even let's me boot into it, after pulling the battery, and using the correct button commands. But if I restart and try to enter again I'm greeted by the official erase everything recovery.
Does anyone know what I'm doing wrong? Do I need to flash root to get the recovery to stick?
Take a look at this video. If you have TWRP installed right, and are going to it through a battery pull and the power button volume down combination, then the screen that comes up looks scary and looks like you'll "format" your phone, but as you see in this video, you don't.

Not sure why it isnt happening automatically (it usually does when flashing things like magisk to root) but when you get into twrp or with root rename /system/recovery-from-boot.p to /system/recovery-from-boot.bak. If in twrp first go into the mount page and uncheck the box at the bottom that says something about system read only first, then you can use the file manager.
Or since it sounds like you want to flash lineage, just flash the lineageos zip (and then optionally opengapps and root). Be sure to format data too (wipe->format data->yes). Then if you dont have lineage on an sdcard ready to go you could reboot recovery so that the formatted data is ready then connect to pc and send the zips over by using adb push C:\path\to\lineage.zip /sdcard/

What I'm thinking about doing is flashing TWRP again, on first boot(of TWRP) backing up my current rom(stock) and trying to boot into recovery again, because if it doesn't stick again, it'll wipe but at least I'll have a backup.
I've noticed a lot of different root files which would you recommend?

What I'm thinking about doing is flashing TWRP again, on first boot(of TWRP) backing up my current rom(stock) and trying to boot into recovery again, because if it doesn't stick again, it'll wipe but at least I'll have a backup.

Sorry for the double post but does the "LG factory reset" stay even after having TWRP installed? Like will I always have to answer yes twice to enter TWRP?

Yes thats always the same.
If you don't flash lineage or something to root stock (I reccommend magisk since the alternative, Supersu, is owned by some Chinese company, and magisk has various modules that do many things) and don't rename /system/recovery-from-boot.p manually (theres a file manager under advanced in twrp) the stock rom will use that file to reflash stock recovery any time it boots.

Awesome I think my issue is not renaming that file and the stock rom reinstalling stock recovery. I've used SuperSU, never used magisk, is there a stickied release thread for it?

You've been a huge help, thank you! I'll report back later tonight, when I can actually work on my phone
So i was able to obtain root aswell as installed twrp, the only issue I had was every rom I tried refused to boot. They just hung at the loading screen, that includes the back up I'd made of stock, is there something I missed?

If you mean the boot animation, the very first time can take a good while, like 20 minutes. Also make sure you've formatted /data if you havnt yet especially going to lineage.

Sorry for the late reply, yeah I think I just let the boot animation go for around 5, I'm gonna have to try reflashing it and hoping for the best, I'll be sure to answer back when I get a chance
OK, I know this is an old thread - but I just got a replacement US996 phone; my old standby has a charger plug problem so I decided to get another one and put a rooted stock Oreo ROM on it. However, I'm having the same issue as the OP. Get into fastboot, flash TWRP (I have the 3.3.1-0 version, as the newer 3.3.1-1 version does not have any download mirrors). The flash appears to go just fine, it says the write was completed. However, when I reboot into adb mode and do "adb reboot recovery" I get "no command" and the little droid with his belly hatch open. So obviously TWRP wasn't flashed. The OP says he eventually was able to get it to work and install root. How did you fix the issue?
Do I still need to do the old recowvery shenanigans that we had to do back when the phone first came out?
Thanks!
I believe you MUST use the button combo to reboot into twrp.

I've done that. The problem is that TWRP hasn't actually been installed via fastboot flash recovery - it goes through the motions, SAYS it's been installed, but when I do the button combo, it actually does reset my phone rather than booting into TWRP.

Disregard the above. Flashed it again (4th time), and it finally took.
The same happened with my wife's US996 now that you mention it. Took a few tries and was a bit frustrating.
When I flashed TWRP on mine it was a "one and done".
Glad you got it sorted.
Thanks - all good. Rooted stock Oreo ROM installed, working great.
