flashing rom on multiple devices at once - ONE Q&A, Help & Troubleshooting

I created a custom rom and i want to install it on 200 OnePlus One (bacon) devices.
there must be a way to do it faster than one-by-one. i think maybe get a high performance USB hub and connect 10 devices on it. then use adb to flash the rom. am I right?
there is little info on the interwebs on how to flash to multiple devices at once.
how would i go about doing that? where should i look for more info?
thank you.
edit:
im using TWRP recovery. and i flash the zip with adb sideload.

Flashing a Kernel via Recovery vs ADB

I was curious as to any difference between flashing a Kernel via ADB using a boot.img or flashing it as a .zip via recovery. Is there a benefit of one over the other. I've always done it via ADB, but I recently tried via a zip file through TWRP but didn't notice any difference, but wasn't sure if I was just being oblivious or not lol
I heard someone mention that when flashing it via ADB you don't get the Modules that come with the Kernel. Which I don't know if that was BS or not, cause as I stated, after trying it both ways, I didn't notice any features taken away i.e. flashed bricked kernel via ADB and then restored stock kernel and then flashed bricked via TWRP, and I was able to activate DT2W/S2W regardless of the method of flashing, as well as OC capabilities, Fast Charge, etc etc.
Just been curious about this for awhile, and there doesn't seem to be much discussion about it, so was unable to find an answer. Dev's always seem to give you the option to download a boot.img or .zip file, and wasn't sure if htat was just due to giving peopel the choice of preferred flashing method, or because of inherit benefits between the two.
Its simply 2 different options of installation. The final result is the same: a boot.img gets extracted and written onto the appropriate partition of your device.
When you use fastboot to flash the img. the executable on your computer does this directly.
When you use a recovery to flash the zip (which also contains the boot.img), the edify script within the zip gives instructions to the recovery on how and where to write the image to.
There isnt really any advantage to doing one over the other.

Fastboot is the tool to which you are referring to, not ADB. You use fastboot to flash image files to partitions directly through the bootloader. That being said, there's no difference which method you use, the end result is the same. Using fastboot requires an unlocked bootloader, flashing through the recovery does not. When you flash a zip through the recovery, the proper destination partition is automatically overwritten whereas when you flash an image in fastboot, you have to specify the proper partition. That's the only real difference.
Excuse me, Fastboot is what I meant yes. My bad lol.
Thanks for the info, I figured as much. Im experienced with both methods and understand how they work. Just wasn't sure if there was a benefit over one or the other when it comes to flashing custom kernels. Thanks bro I appreciate the help. I will stick to flashing via fastboot then. I just prefer to do it that way.
I also use flashify sometimes as well. Seems to work pretty good.

maybe a stupid question, but the kernel is all saved in boot.img?

Yep Indeed. What you can browse is /sys, which are the "files" the kernel manipulates to do what it wants...
..but browsing here is of no benefit to changing a kernel

Unlock your device and just use the a custom recovery.

can we change kernel alone
i am using SENSONIC with stock kernel can i change kernel alone.
I want to change to franco kernel . Is it enough installing zip using recovery or i have to do fresh install of the ROM.........
Thanks in advance.

Marshmallow Rom

I'd like to install something like this "[S6 G920F/S6 Edge G925F] [6.0.1] [3DPBK] [05/03] [v3.2] Pure Stock ExtraLite Rom" but if I wipe everything I can't seem to get the ROM onto the device to flash via recovery. I believe there are two ways potentially adb push and adb sideload but I've no experience with them. I either get a sideload error about "cannot read" for the filename or I get an error closed with push.
I'm happy to continue trying to work out how to do it but am I on the right path with these or is there a better way to get the zip onto the device?
thanks

Why not put your phone into download mode and flash via Odin if you have a pc

You need the new boot loader if you come from 5.1.1.
Thanks guys. The ROM isn't available as a file that can be flashed through ODIN. My issue is if I wipe the device I can't get the file on there to flash it through recovery. I thought adb may be the way but I can't get it to work
Long live the separate sd card in my old S4...

I can however load a standard rom, flash recovery and then flash the zip. Aroma gives the ability to wipe data so that's as good as I can get it.
thanks for the help guys,.

The real question is kernel source. Not much reason to unlock the bootloader without that.

Exactly.
I'm not holding my breath.
I think I'm jumping ship.
thought Magisk works now with just an unlocked bootloader... or was it the other way around... lol
*edit*
Via Magisk Manager (Only support v14.0+):
This method does not need root, and also does not require a custom recovery.
However, you MUST have a stock boot image dump beforehand, and also be able to flash the patched boot image, either through fastboot/download mode or ODIN
Guess we'll need some patched boot image... which I'm assuming no one has yet... lol

Magisk manager will patch the boot image when installing magisk 14.0
We just need the boot.img from the rom or the OTA before it installs.

That's IF You can access the OTA zip. A lot of times it's downloaded to /cache which is not accessible without root. Some OEM's have it downloaded to the SD card but most bigger OEM's have it downloaded to the cache partition

Some people got the update today. If you happen to get it can you try to pull the boot?
I have the update waiting to be installed.

in the build thread, a user was able to capture the OTA url. the only issue, the boot.img is stored in the payload.bin file. Are you familiar with this file and how to extract it?

At this time no. Hopefully soon that will change.
In the Andy Rubin AMA, the official Essential reddit account posted that the kernel and factory images would be released to the public "in the next few days". That probably means next week, business days and all, but it looks like they fully intend to support external development of this phone, and soon. Makes sense--why else would they allow a bootloader unlock from the get-go?
In adb I can find my phone but once I adb reboot bootloader and fastboot devices it doesn't display. Plz help

You need to select correct driver in device manager, maybe even install different drivers

Does anyone have any advice for getting the phone recognized. I installed android studio and google usb drivers. I've unlocked bootloaders on onepluses before but nothing happens when I type fastboot devices, and it stays at "waiting for any device" when I try the unlock command.
Yeah, try another computer. Seriously, my main PC just didn't want to work with the phone. Used my laptop, worked fine. Can't think of anything different, both are Win10, both have the same drivers and sdks. Both work for my other phones, just not this one. Didn't hurt to try. Of course you'll need access to another computer but if you have one or more extras, worth a try. Worked for me.

USB C port is busted, only charges but no data

It's extremely inconvenient since I can't transfer files via USB to PC or to another USB C device.
That's not too much of an issue Thanks to WiFi and NFC / Bluetooth.
But now I want to upgrade TWRP to twrp-3.2.2-0-ocn.img
And reviewing the steps just realized I need to flash it via USB to PC... so I'm kind of screwed in that regard.
Is there a way to flash TWRP via TWRP itself?
my goal is to upgrade to Oreo ViperU_2.2.0.
Currently on ViperU 1.8.0 with the old twrp-3.1.1-1-ocn.... that means I'll run into problem according to others that already upgraded to Oreo ViperU_2.2.0, without first upgrading TWRP to the latest version.

You can install TWRP image by going to the install selection and then change zip to image and flash to the recovery partition

Weee... yaay!
Yup, I just did it that way and it worked!
Thanks!
I did not realize that was possible, cuz I've always been flashing Zip files, never realized there was an option (the 2nd button which I never used) was to flash an image. LOL :laugh:
It's very useful when restoring a twrp backup w/ clean system image and then flashing a stock recovery to go back to stock without needing a PC

Unable to Root/Flash TWRP on OnePlus 7 Pro

Greetings to anyone that may see this - I am new to the android root thingy, so I apologize in advance if I have a stupid question. I have only rooted an old tablet with Kingoroot which used SuperSU as the root manager. First off, I want to address TWRP. What is the difference between the OP7Pro "guacamole" and "guacamoleb" (the "b" is very important and intentional.) I tried the regular guacamole image, but the phone didn't seem to want to boot the image. I am going to try guacamoleb. If I flash TWRP, can I boot my device normally? Some sources say yes some no. Thanks for all your help in advance!

Haven't seen guacomoleb (different code name to me implies a different device, but I'm not sure in this case). Just use the file from the dev's TWRP thread: https://forum.xda-developers.com/on...nt/recovery-unofficial-twrp-recovery-t3931322
Unofficial version -75 is the current version. Use the version ( Q versus Pie) for your current Android/OOS version. Might be obvious, but some folks have asked about that.

Per the developer in his thread I linked above, for a stock device, if you flash TWRP, you should root (with Magisk) or the phone might not boot. Some folks have reported that they can flash TWRP and not Magisk and still boot. But there is not point in risking it, since your intent is to root anyway. Fastboot boot TWRP img, then flash TWRP installer zip, and just flash Magisk right away at the same time, then reboot. It's pretty easy.
Also note that installing TWRP is somewhat optional. You can just fastboot boot TWRP img, then flash Magisk to root. It is a matter of preference whether to have TWRP installed or not, and folks are pretty split on this. My opinion, TWRP installed (while not required) does give some potentially useful features if things ever go wrong. I personally don't see much advantage to not installing TWRP, but just my opinion.
Hi there. I ran into similar problems when I was a Root noobie (which I still am). Try the All In One Tool that can be found in this forum. That will help you flash TWRP. It got me there when I was struggling to Flash TWRP.

Use adb & fastboot via powershell
Get the adb files in a folder
Copy the twrp.img to the adb folder and on phone /storage/emulated/0/
Get a copy of the twrp installer on your phone anywhere works
Open adb folder
Hold shift and right click a empty space
Open powershell & type
Adb boot bootloader
Fastboot boot twrp.img (you can drag and drop the file into powershell if your lazy like me)
Flash the twrp installer on your phone
Done?
Reboot and go back into recovery to see if it works
Tip for updates:
After you get the update
Flash via twrp
Then flash twrp (so you don't need your computer)
Flash magisk if you want superuser
Reboot
Reboot recovery
Flash magisk again (seems it takes two flashes)
None of the tools work for my devices anymore just powershell
All in one doesn't read my fastboot
Cmd has a remote error after attempting to boot it.

Just noticed that the TWRP "guacomoleb" is the "unified" version that works with both the OnePlus 7 and the 7 Pro. Shouldn't make a difference whether you use the "unified" version or the 7 Pro specific TWRP.
