MR207 Now I know why the gpt is corrupt : [ 2.209381] [c1] GPT:Primary header thinks Alt. header is not at the end of the disk. [ 2.209381] [c1] GPT:15253503 != 15269887 [ 2.209411] [c1] GPT:Alternate GPT header not at the end of the disk. [ 2.209411] [c1] GPT:15253503 != 15269887 [...

PuYaU Yes for now ... but you cannot format a partition to f2fs. The encryption on los15.1 have a little difference the footer reseved space is allocated automatically by the framework so the option to reserve space is useless. For this reason mkfs.f2fs can't reserve 16KB at the end of the...

Encryption fully working on the latest rom and some bad denials from selinux removed :) sm-j320fn => lineage-14.1-20200125-UNOFFICIAL-j3xnlte.zip sm-j320f/g/m => lineage-14.1-20200125-UNOFFICIAL-j3xlte.zip

There is maybe a big problem with encryption so it's not a good idea to try it now, I need to verify all ... A sim not detected problem on the j320f. I will check all and also I found 2 selinux denied, one on at_distributor and one other on the audioserver :x 01-20 17:14:57.656 3291 3291 W...

Always no gpu driver :x

Yip, I changed one or two things to get the encryption works ... not fully tested, I don't want to crypt my phone. https://github.com/djeman/android_device_samsung_sharkls-common/commit/06a6ca6260caefd95c30836b31cbd3acb22ecf02...

Sry but I don't understand what you cant to say with "an automated auto clicker". So it's definitely not possible to use an old gpu driver on oreo and sup. I think the only solution is to port the sprd adf (atomic display framework) driver to replace the framebuffer driver and after maybe we...

Yes, the model with nfc is with a "n".

Since the 25 december build :)

I tried all things possible on the hwcomposer and gralloc, tried a lot of versions to finally create my version ^^ The problem is not here it's a really inside the mali driver. The new release to test latest gralloc modifications : lineage-14.1-20200104-UNOFFICIAL-j3xnlte.zip...

The memory used by the framebuffer is defined in dts files for 3 framebuffers so 720*1280*4*3 = 0xa8c000 (screen size = 720*1280, argb so 4 bytes by pixel and 3 framebuffers)...

Yes very very difficult ... a guy have make the job for linux in 10 years and it's not completely finished :x (lima driver) But maybe it's possible to modify only some parts. I found a debug version of the driver so ida works fine on it and to be compatible with android there is a group of...

I will rebuild the full rom to make a good test, on my phone I've do not see any difference. Thanks for the reply on the test. For oreo the problem is always the same ... maybe if I recreate an old surface class to cast the new to the old before to send it at the driver ... or I can reverse the...

https://github.com/djeman/android_vendor_sprd/commit/9eba58ab682207fa89079113406d7e46e2ba3b6b I forgot one line in the test build :x

Very hard to build rr nougat now, all rr repo has stop to merge lineage commits since the 13 december 2017 :x I have create a new test build : ... bad test need to be rebuild ^^ I separated completely the framebuffer device and the allocator device ... it's a try ... I need it for los15.1 ^^...

Maybe if you know the difference ... there is only 2 differences : - Inside the kernel, configuration files for the material are not identical (m compatibility and lte radio memory size) - On the j320f version the nfc is removed (driver and all softwares) So if you use a version fn on a f I...

Yip, I found some missing options in our kernel compared with the android base config: - CONFIG_PM_AUTOSLEEP - CONFIG_IP_MULTICAST - CONFIG_NF_CONNTRACK_SECMARK - CONFIG_NETFILTER_XT_TARGET_SECMARK - CONFIG_IP_NF_SECURITY You think it's a good idea to enable it ? A test kernel for the j320fn...

pacurarelvis With the latest gpu driver added in the rom all old "boot.img" not works if you do not change the gpu module (mali.ko). The driver is not the same version so the userspace is not the same.

Ah ok perfect because it's not a little patch. For the moment I pushed nothing on github but I changed the gpu kernel module, modified gralloc and hwcomposer, replaced the mali binary driver and putted a lot of patches on the lineage sources (surfaceflinger and some headers). And after some...

MR207 I tried to get some flickering on youtube and I see nothing. How have you get a problem ? Maybe just no chance ? ^^ I did a lot of tests on the hardware composer and the flickering problem was inside the gpu driver, some surfaces not released at the good time.

New christmas builds :D lineage-14.1-20191225-UNOFFICIAL-j3xnlte.zip lineage-14.1-20191225-UNOFFICIAL-j3xlte.zip Maybe the best build I have ever created ... or the worst ^^ It needs some tests but for the moment all works very fine on my smart :) 2019/12/25: - december security patch added -...

Nope nothing on mms ... it works anywhere excepts for you :x You do not need to enable data roaming ? And have you reset the apn list with the 3 dots menu and reboot after ? Sometimes it's the solution ... I changed my operator at the beginning of the month and to fix mms the only solution was...

You're "out.pit" is an empty file. MR207 have demonstrated that it's not necessary to modify the pit. If you are not good with an hexadecimal editor do not try to modify the emmc manually :x My twrp recovery can handle all operations with a script in a zip or by adb.

A big protection system very restrictive => https://en.wikipedia.org/wiki/Security-Enhanced_Linux It's only to make a test, a lot of custom roms not active it. https://github.com/djeman/android_device_samsung_sharkls-common/tree/cm-14.1/sepolicy

MR207 Have you disabled selinux before to try ?

system.new.dat, System.patch.dat and system.transfer.list are together the system partition image. There is a lot of tools to decompress new.dat. Not protected, if you can't open the build.prop it's an other problem. The twrp reads only normal zip files.

I don't want to download your rom ^^ It was just an information, if inside the zip you have a system.img file so it's normal to have a size error when you try to flash it. Disk image is bigger than the partition. But my rom do not use partition images so normally you can flash it if the space...

Ok so you have changed 4 numbers in the gpt header and after you have formatted the 3 partitions. Thanks :) Inside your zip the rootfs is a "system.img" file ? Because in my rom I don't check the size, I choosed the old mode with all files and a big script ^^

Yeah congrats :) So it was only an error to use the software ? We can modify only the gpt header and all will be ok after to have formatted new partitions ?

Not really, my twrp have adb so you can restore the mmc if something is not ok. And yes I think you need to edit it manually because it's not a standard gpt. First the header have not the good length compared to wikipedia ^^ And secondly each part entry have a guid and a name predefined...

Yes after a reboot, partitions are modified I think ... need to be tested but normally after a reboot it's modified. But only the partition table so to make proper you must to format the 3 partitions. Before to format maybe system will be continue to work but the 2 others have not the same...

MR207 I updated my partition scheme to add the gpt header, now it's complete => https://forum.xda-developers.com/showpost.php?p=81245313&postcount=2509 I checked fastly on the hexadecimal editor and it seems to be simple to modify a partition. In my partition table I have : to dump the "gpt...

Opengapps are fine, I never used pico it's too light. Opengapps or thing aroma the two install the gapps inside system it's not really a choice but all updates are installed on data :x So nothing changes, with aroma you have just some choices ^^ Yep with a shell and "dd" it's easy to dump and...

.... it's not possible to change only the size of the latest partition ... it's the latest, it uses the remain space ^^ offset size name (filename) part 0 512KB BOOT (spl.img) EMMC_PART_BOOT1 /dev/block/mmcblk0boot0 0 1MB BOOT2 (spl2.img)...

We have a samsung to modify partitions I think you need to modify the pit file before to flash it with all others parts in odin (CP, BL ... very important) ... it's more dangerous than all others flashes and do not forget to backup all before (efs, ...). I never tried. Pit magic do not seems to...

Yep I can :) BL_J320FNXXU0ARB1_CL12808116_QB17100580_REV00_user_low_ship.tar.md5

Ok so it's not that. Nothing is modified on the mms service but it not works for all ... your honor uses the 3g on rmnet1 and the j3 try to use the 4g on rmnet0 with no success ... I will try another thing when I will got an idea :x Thanks for logs and the build.prop.

I make some progress on eap sim/aka => https://pastebin.com/YBxXLm90 And maybe it was the problem for ims/volte, eap-aka is used for the authentification of the ims/volte ? There is some weirds debug logs as "IPC_SEC_IMS_AUTH_TYPE_3G", "SRIL_IMS_AUTH_MAK_CODE_FAILURE", ... on the sim-aka...

Yip, I started the reverse of my samsung wpa_supplicant to extract the eap sim/aka code. https://pastebin.com/YBxXLm90 So if someone want to help it would be very appreciate.

Thanks, few days is not a problem ... the j3 is old, nothing is urgent and normally all development is stopped. Me, I'm trying to reverse a part of wpa_supplicant to create a eap-sim patch for some samsung ril drivers. But it's hard, I make just a try to test if I can pass the challenge :) The...

lmi01 So with this config : <apn carrier="Carrefour Mova" mcc="260" mnc="01" apn="www.mova.pl" type="default,supl" /> <apn carrier="Carrefour Mova MMS" mcc="260" mnc="01" apn="mms.mova.pl" mmsc="http://mms.mova.pl:8002/" mmsproxy="212.2.96.16" mmsport="8080" type="mms" /> You have an error...

The new release : lineage-14.1-20191107-UNOFFICIAL-j3xnlte.zip lineage-14.1-20191107-UNOFFICIAL-j3xlte.zip A little changelog : - october security patch added - mms workaround patch removed - ril driver patched to remove an error on all "chown" (unknown group id 8001 - Operation Not Permitted)...

Yeah, I'm not alone :) No one of you have found some sources of wpa_supplicant that uses libsecril-client to communicate with the sim ? One guy have asked me for the eap-sim but as always it's a samsung implantation ... I removed 2 errors on the ril to understand all the system to get eap-sim...

Yep but ... so ... someone have a j3 here ? :D

https://github.com/djeman/android_device_samsung_sharkls-common/commit/bc3873eeb020c07eb65f9cb764164de221212789#diff-1266e32bfe8142dc3fe87826463ac32f Do one of you remember why I added this workaround ? :x Because it's not very good with one apn for both data+mms ... I'm trying on my j3 without...

https://review.lineageos.org/q/branch:cm-14.1 Always the same thing, lineage updates.

It's only lineage updates as declain12345 said. I only launched a build without modifications except the lineage repo updated. I agree it's not fantastic but it's better than nothing :x

gellmar With the patchset 5 all timezones work for me too ;)

curiousrom gellmar All timezones work except South Georgia GMT-02:00. But I tried the patch set 4.

Ok, yesterday I was tired ... I missed this part of the message ^^ So I will build the rom for my device and I will try myself.
