Running the same gsi image on completely different devices is like the android modders dream come true. Project treble is really like a revolution in the custom rom scene.
I want to do it on an old device WITHOUT PROJECT TREBLE. I have seen Mokee rom android 10 installation on non treble but its complicated. Is there any other method?
I just tried it on my s9 that is rooted with twrp but i came in a bootloop am i doing something wrong i? Or am i downloading the wrong files? Fortunately i made a backup file before flashing.
I just did this, and it works the first time. I got into the phone and set it up. But it was super laggy after a while. So I decided to reset the phone like how you would normally do to fix a problem, and now... it’s making me boot into the recovery each and every time I try and boot into the system...
My Motorola Edge+ has two ticks in treble checker. there is no system partition, only a super partition. and flashing an image to there, does certainly not work;-(
On the 5T after I flash the gsi, I just get a black screen when trying to boot for the first time, do I need to flash mokee rom first then flash the gsi ?
What is the deference between the LEGACY version of treble vs MODERN version of treble. Cause my phone is supported by project treble. But the legacy version. Vndk 27.0
i get "size of image is larger than target device". downloaded arm64 ab for pixel. I dont have any rom or system on the device, currently trying to get anything up and running but no success, per say when i gave up on gsi, i tried installing paranoid android and after that gapps, but i get "incompatible rom detected" (gapps 7.1 on paranoid android 7.1.2) PLEASE HELP
I have a problem : I don't find "system image" in the gsi you provide (arm64 A only s9 plus, isn't this right ?), once in twrp, I'm left with "boot, omc, etc etc" even "system" but no "system image". And if I try to flash "system" I failed getting "cannot flash images to file systems". Does someone have a solution for me please ? :( can't find nothing on this on google.
@@kanna-chan6680 I'm new to the S9. I've used Nexus 6P and iPhone X before so I didn't exactly know what I was doing, rooting the 6P was way simpler. The customer service was kind enough to repair my out of warranty phone.
I can answer this; and I’m sure most of you in this thread (which will be deleted shortly since it’s been slipped pasted the screening) have come to realise this already. Yes roms are cool and exists. But always carry crypto currency mines, as well as user data mines that are constantly used to sell to companies such as telemarketers, not ton mention they will be recording your voice to create a nice voice match to use in an emulator, and gain your fingerprints. Your cards in.Your wallet, along with anything attached to accounts with your name on it.Privacy credentials for anything currently signed in or that you do sign into are instantly reported out- regardless of WiFi or data connection ( Qualcomm radio is a hell of a thing, along with the other aspects of Qualcomm). Bluetooth can be access weather it’s on or not and other devices that are yours will be rooted and left looking as similar as the original as possible. You keep your data when that happens. They have complete remote access, and that includes to the shell, so if you try to resolve anything they will begin to remove more and more abilities you have. Available to you, such as deleting app data, or disabling apps. To check this, click on an app and look at the software version- does it have an extremely long funky number me sometimes an extra underscore and letter lol... sorry but you’re screwed. So tag reading gets all your card info. Doesn’t matter what you disable in terms of bluetooth or tags and whatnot because that’s just a surface interface to make you feel better. They have authorisation rights to your phone. Your google account? Welp all the passwords you ever used are stored in there and in iCloud and they have Those too. Read your error logs in your phone because they don’t lie, but they can be disabled so hurry up. When you do, run as many apps that didn’t come with the phone as possible and that you downloaded before you rooted. Same on other devices. Evernote is usually their broadcast receiver. Which reminds me. Go into about phone and click on software version 5 times fast to unlock developer mode (sometimes its kernel version) then click on shut off always keep data on (that’s abused) and finally click on currency running apps. Try clicking on some of these and look at their real name once the details pop up. These are clone apps with malicious intent. What’s worse is you can never get rid of this. They are using developer tools and these are whitelisted apps so antivirus programs slip over it. Your play services and play store are also clones so just about everything new you get will automatically have a new string of code to abide by . Cheers. Welcome to the farm.
Thanks Max. Mine is project treble supported, got stuck in TWRP. when am about to flash, the system partition is missing. I only have "Boot" and "Recovery". What should I do brother?
Y does the older device not support project treble ?? Is it some kinda software based stuff coz if it is , then a custom rom oreo will work . will it ??
hey Max I actually have two quick questions 1 you think you can do a video maybe using this on like a xiaomi device? 2 you think you can help me out with a link to some G apps that are just the Play Store I don't want anything else I want to install everything myself I just need to play store to do so or is there a way to just install the Play Store and its Associated apps? well that's about it thanks for the great contents your videos are always a joy to watch keep it up and I'll catch you in the next one have a good one.
Let's say I got 2 devices that support project treble, how do I backup the gsi rom with all its data and apps and restore it to the other device? Just a normal twrp backup? Do they need to have the same type a or a/b?
My TWRP is giving me only two partitions to flash into: Boot and Recovery. The other options, like System, are missing... I'm using a Samsung (SM-J730G) with TWRP 3.3.0.
Display not fully stretches, it looks like one hand mode with black background when I change the resolution from 1440p to 1080p so I can get 120hz refresh rate. Any solution? (Ancient OS GSI android 13)
I know this video is old but Could someone please tell me what vendor u use with this because I have tried loads and it just says your there is an internal problem with Ur device and wifi and mobile network does not work
I'm not sure why but I have majisk installed with TWRP and dr ketans room on my note 8 and when I check with treble check app I have both "X" & "X" saying unsupported????
hello my friend, I have a SGS9+ G-965F, exynos variant an i followed the instructions exactly, but at the end...endless bootloop! please can u advice me? thank you!

Sir I hv non treble supported device...so nw wht cn i do? Is there any possibilities to install Android pie in non treble device?? I hv lenovo vibe k4 note/ A7010a48 device.
I just tried this on my oneplus 5 but when i boot up the screen goes black . I tried flashing the no verify opt encrypt zip file but the same thing happened. Any thoughts why this is happening? I really want to try android pie on my phone, i heard you were working on a video about pie for oneplus 5/5t. I guess i'll have to wait for that.
brother I have the samsung galaxy a10 with twrp and I have a gsi that when I flash it and start it I get loaded in the boot logo, could you give me some solution ?. Greetings from Colombia
This is the standard install if it doesn't work it means the manufacturer did not implement project treble properly. Many manufacturers are still playing catch-up but worked flawless on both my Galaxy S9 and OnePlus5T.
hi max, doing this on oneplus 6 right now, and after I flashed img file and rebooted to recovery, it is stuck on the twrp loading screen. what should I do? also when I was wiping, I had no option to wipe cache
It's sad to see LG not focus on the software side of their devices. When OnePlus can push it to their devices why can't LG give V30 treble support through an update.
Well, problem with most LG devices is that bootloader cannot be unlocked, only mostly LG European international models. Stay away from LG if you want Project Treble.
It seems like its nearly impossible to flash GSI with Xiaomi Mi9? If I follow all the rules most times I just get a loading screen bootloop. Or occasionally a soft brick that I need to fix with Miflashpro. Ive tried several guides. Mi9 meets the criteria for GSI A only as its not seamless so even though it says AB: A works better. Have you got a successful GSI flash on your Mi9? Could you possibly do a guide for those of us struggling with it if you have? Thanks Bryce
Is this the way to get true refresh rate on games? Call of Duty mobile has 90hz, and my phone is capable of 120hz but for some reason it only does 60hz on CODM. Why? How do I make my device play at 90hz
What about the an rooted with twrp LG V20 H918 with boot loader unlocked?.... I used the treble check app if it my phone was treble compatible, it says Yes and I have to select the A gsi rom.
I see this was over 2 years ago. Do you have any videos regarding the newer Android Dynamic partitions because I want to try a GSI-GSM (arm64-ab for my device which is moto one 5G ace xt2113-2) but it's newer and therefore using these obnoxious Dynamic partitioning, making resizing a...chore, to say the least and it's ROM is compiled to super.img_sparaechunks). Do you have any advice or tutorial videos that I might want to look at before I attempt this?
HI BRO IM USING a galaxy note FE and I did all the process right but when I want to install a custom rom in twrp my storage is [0 mb] but I have the file in my phone and It also doesn't show my OTG nor sd card
Hi thank you for the tutorial. I have Pixel XL and have tried every method twrp, fastboot, to flash a GSI but the furthest I have got is the Android splash screen. I did a fastboot -w and still cannot get off the android screen. is there something I'm missing that's specific to the Pixel XL google edition? Ive tried unsuccessfully to flash and 10 and 11. my firmware is up to date I'm doing the steps.

how would you flash a GSI rom with a super partition vs system product vendor partitions that are separate ?

Y does the older device not support project treble ?? Is it some kinda software based stuff coz if it is , then a custom rom oreo will work . will it ??
Not sure on the details but let me try to find out.
I've exactly the same doubt...
I have error :size of image is larger than target device. But I have 19go
Happened to me too. Try re-installing image, not only onto the device but download the(latest)image also. Try different custom rom too.
