[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] wickedjoe1:
I can't seem to be able to use adb commands when the phone is booted into TWRP. adb Does work as expected when the phone is booted into android.

When in TWRP however, "adb devices" lists my device as "offline". All of the adb commands fail to execute complaining the device is offline. The various start/kill/reconnect commands likewise don't do anything.

Is this behaviour expected?

When trying the same on my Nexus 5 TWRP 3.1.0-0, "adb devices" lists the phone state as "recovery" and all the commands indeed work. Is the A8 an exception? Or did I miss something?

Thanks for any insight!

Phone is A530F, TWRP 3.2.3-0 from the twrp website.

If it isn't listed here:

https://twrp.me/Devices/Samsung/

Or here:

https://twrpbuilder.github.io/downloads/twrp/

Then it is not available.

What you can do, is use the 2nd link and if i remember correctly, you can submit a request and your phone will send data to begin the process. Read what to do, follow the instructions carefully of course, and you'll get your prize. Might need to get an app, but i did this on the A5 and was using the recovery produced prior to official status. Chances are it's been started if not already available. It'll eventually become official.

If you're impatient and have a good understanding of the process, you can invest your own time and do it yourself. Definitely do what is required and just have a look once a day, once a week.. and it shall happen.

Hi BlackMesa123, thanks for great work!

I have followed the instructions carefully and repeated several times. I initially tried things on linux with adb and heimdall, however heimdall was failing to flash, so I returned back to your exact instructions for Windows using Odin3 v3.13.1 you linked. When I try to flash twrp-3.4.0-0-jackpotlte.img.tar into my Samsung Galaxy A8 (2018) aka SM-A530F, Odin fails consistently with this log:

I believe my phone is not RMM locked because I see Developer Options in my settings. I tried the process with OEM unlocking enabled and disabled in my phone Dev Options. No success yet.

I googled the issue for a few hours, however people mostly report seeing RQT_CLOSE when phone is RMM locked, which I believe is not my case. Maybe this is related to the recent Android update I installed yesterday.

yes, latest version for our device "jackpotlte" is 3.5.1_9.0. You can download it from the official twrp website.

@BlackMesa123, bro the screenshot ability is kind of bugged in the latest version of twrp, all the colors are inverted in the screenshots taken, for example blue appears red, pink appears purple, etc. This is kind of a bother if you want to share some twrp theme related data/ files.

jackpotlte TWRP will never boot in your device since the recovery.img requires the correct kernel/dtb. I'm willing to rework the device tree/kernel since it hasn't been updated in a while, will also look at making builds for this variant. I just need people to test since I don't own the device anymore
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] amaris.homero:
It also failed for me. Device would not boot due to "error while updating". I had to use Odin to reflash stock firmware. I wonder what I did wrong.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
Seems like something is off with the latest 3.7.0 build in twrp.me. I'll try and see what's wrong once Samsung releases the latest kernel source code I requested (knowing them, a month at least)
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] DuskGolem:
I can confirm that twrp 3.6.2_9.0 is working absolutely fine for me on A530F running latest stock rom (nov 2021 security patch, CSC is XSG "United Arab Emirates"). I have flashed using odin as well as from previous version of twrp and everything works fine. I have also clean installed the OS atleast 4 times in 2022 alone and never had a problem with it.

The only reason I can think of that is causing these problems for some of you is "RMM State Prenormal" which hides the "OEM Unlock" option from developer options and only appears after keeping your device on for 7 days straight without shutdown or reboot. To bypass this is pretty simple. Simply follow the guide HERE. Also I suggest to re-read THIS guide about rooting and installing twrp on our device as a refresher.

Hope this helps.

P.S. twrp 3.7.0_9.0 is not working as @BlackMesa123 said in the post above. It gives error about target device partition being too small for the selected image.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Noisette42:
Bonjour, et bonne année à tous,

Un grand merci @BlackMesa123 et tous les autres contributeurs à la création de l'amélioration de notre téléphone.

Je me suis inscris sur le forum, d'une part pour remercier et d'autres part pour indiquer qu'hier soir le 06 janvier 2023 j'ai pu installer TRWP et que cela fonctionne après une lutte acharnée de 2 jours.

La raison en est simple, c'est que les TRWP supérieur à 3.5.0_9-0 ne fonctionnait pas avec ma Rom custom constructeur.

Donc je pense quand 2023 si vous n'avez jamais fais quoi que ce soit sur votre tel, il vous faut flasher la version 3.5.0_9-0 depuis Odin sur votre tel pour pouvoir ensuite rooter et/ou installer une rom custom.

Je n'ai pas eu besoin de m'occuper du RMM car mon telephone n'avais pas ce verrou.

J'espère que ça en aidera plus d'un.

Hi bro, thank you for your job, I'm very happy it was ok. Sorry for my English, I need to improve it.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] RootedLee:
Hi @BlackMesa123 Is there any news about TWRP 3.7.0 (with hopefully correct image size)?
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] RootedLee:
The same "Size of image is larger than target device" error was also occurring with TWRP 3.7.0 for the Galaxy S7. Ivan_Meler found out how to fix it and posted a fixed version for the S7 here. It's not compatible with our A8 (flashing fails), but at least there is hope on the horizon.

@Ivan_Meler : is there any chance you can apply the same fix to TWRP for our Galaxy A8? The non-flashable 3.7.0 recovery images are here at twrp.me, and the device tree source code (outdated/ 2019) is here at GitHub.

That would be really great because this has been a pending issue here since last October. Hope it's not too much of a hassle (y)
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] Ivan_Meler:
i can try but communication with twrp team has been a pain so even if same fix applies here no idea when and if it would get merged
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] RootedLee:
Hi @Ivan_Meler Thanks for trying. I'm aware of the communication issues with the twrp team. Merging would be optimal but secondary. If your fix works here, too, it would more than suffice for now.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] RootedLee:
Unbelievable but true: the knowledge how to fix this (addBOARD_RECOVERYIMAGE_PARTITION_SIZEin the Image section of BoardConfig.mk) has been around since at least 2016, see here ..
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] RootedLee:
@BlackMesa123 from what I see, all you'd need to do so we get beyond the v.3.7.0 Size of image is larger than target device error is to addBOARD_RECOVERYIMAGE_PARTITION_SIZE := 48234496in the Image section of BoardConfig.mk (taken from Ivan's android_device_samsung_herolte/BoardConfig.mk).

@Ivan_Meler please correct me if I'm wrong
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
No, this flag is only used by mkbootimg.mk to check if the built image size is bigger than the one set in BOARD_RECOVERYIMAGE_PARTITION_SIZE, in this case the build will fail. Also the S7 recovery partition size might not match the partition size in this device.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] RootedLee:
Ok - thanks for trying. Ivan has figured this out, so hopefully he can share whatever more code needs to be changed or added.
[Samsung Galaxy A8 (2018) ROMs, Kernels, Recoveries] BlackMesa123:
TW_EXCLUDE_PYTHON := true

is probably enough to free up enough space in ramdisk and contain the recovery.img size.

Hello guys, how i can make sure my phone isn't RMM Locked?

i read the topic about RMM, it said

How to know if you are locked

There are 3 things at this chapter:

1. "Only official released binaries are allowed to be flashed" message shows up and now you know for sure you got locked outside your phone

2. Missing OEM unlock toggle in developer settings, if your device has FRP

3. "RMM state = Prenormal" in download mode

Last week i checked and enabled the OEM unlock toggle. But when i flash the TWRP 3.7 through odin. After restart my phone only shows the messege like this.

And i flashed the stock rom to make my phone work normally.

Now i don't know where was the problem , not sure my phone is RMM Locked or not :(

Hi all. I have an unlocked A8+. I rooted when I had Nougat. I installed the oreo firmware from Columbia and the phone works great. I like the enhancements. I followed the instructions to install the new twrp. Took a bit but got magisk working and root explorer but had issues with busy box and titanium bkup. No biggie. The issue I had is the when I went to send a text I got an error and then I noticed I had no signal. So I checked and low and behold I had no mobile networks in the connections list.
