Your ROM not start ?
[Samsung Galaxy J7 (2017) ROMs, Kernels, Recoveries] Alvin50:
I have no problems in starting this ROM, I only asked to be sure I did all I had to, because of some problems I have seen, for example that one of the screen that turns black when I take a call on or call out. That moment, the phone appears to go out of control, black screen, buttons unoperative, until either it powers off itself after about a minute, or I shall force it to power down to regain control. So my first approach is to see if I missed something by the way, then I'll try to hunt a possible cause in the setting, and, at last, set guilty the ROM itself. Some other times, if I let the phone on and put it in charge, instead of going to sleep, it turns off and then takes four/ five times the normal time with PWR button pressed before lighting again, or refuses to start with power button and needs the forcing to Odin download mode (Vol-, PWR, Home, then Vol-) to restart.

Then, can you please confirm that the install checklist I followed and forwarded is correct?

Kind regards

Hi Micro[ice],

your steps where the key to succeed!

* GPay refuses to work, because it detects a device with root access - can i omit the Magisk step?

* Is there a way to remove the navbar on the bottom? Because the J5 has a 3 hard keys.

[Samsung Galaxy J7 (2017) ROMs, Kernels, Recoveries] thalesv666:
Salve meu consagrado. Tô tentando há 2 dias inteiros instalar essa rom. Não sei exatamente onde tô errando. Já tentei outras roms daqui e outros processos, não importa o que eu faça, só dá boot loop. Primeiro fiz todo o processo de retirar RMM STATE prenormal lá, instalei a ultima rom clean BR binary 10 e em seguida a twrp 3.3.0-0, conforme as instruções. Depois disso consigo entrar no recovery e instalar as coisas, mas não importa a ordem que eu siga, só dá bootloop.

tl;dr I've tried multiple times to install this rom but all I've got is boot loops.

edit:

SOLVED

I installed the Orange Fox recovery and it works!
[Samsung Galaxy J7 (2017) ROMs, Kernels, Recoveries] jaggedN:
Hi again,

i recognized, that the installation works without step 7.

The problem with magisk is: after doing a update the boot screen is shown forever (i think this i because the update installs a magisk version which is not adopted for this GSI version.).

But even without Magisk the app GPay does not work.

Is this the kernel or something else?
[Samsung Galaxy J7 (2017) ROMs, Kernels, Recoveries] Micro[ice]:
ofc works without magisk thats optional but whats the point of GSI without root ? but again thats your preference

as u noticed u get bootlop if u update magisk so dont update it stay with v20.3 or u get bootlop ? (thats for all gsi)

idk if this is the right answer but i read somewhere that once you root rom/gsi it breaks some apps like google pay , samsung health , samsung pass and secure folder basically anything related to knox so blame google ?

try to go magisk manager -> swipe right -> magisk hide and tick google pay and see if it works ? (this kinda hide magisk so the app think u dont have root)
[Samsung Galaxy J7 (2017) ROMs, Kernels, Recoveries] Ticamus:
Hello, I can't get it to work. I followed every steps but I always get an inifinite boot loop (I used the magisk that was in the first post)

[Samsung Galaxy J7 (2017) ROMs, Kernels, Recoveries] jaggedN:
Without magisk: gpay does not work

With magisk and hide: gpay does not work

The point is: on another phone with lineage installed it works - so custom kernel are not a problem...

How to update havoc os 3.4 to 3.5.2?
[Samsung Galaxy J7 (2017) ROMs, Kernels, Recoveries] Alvin50:
As I'm trying variuos Treble-like OSs on both J530F and N910C, I'm looking for help in the respective threads, and shall post similar queries in different threads. I apologize for this, but I don't see a better way to find the right people.

I'm having problems with calls: If I either try to reply to an incoming call or to call some number, suddendly the screen goes black and I cannot do anything else than trying to reset it.

Is it there some trick to have the call screen visible and, possibly, set loud voice on?

In a bunch of like systems I never succeeded in calling!

Mumbling on this failure, I remember that, among the button pressure to operate the call, and the black screen, I see a flashing blue screen that could be the right one, that instantly crashes, as the program hadn't all data needed to its work. Could it be some personal data I presently never compiled? Or some Google service needed that I, by default, deny? I never installed neither GApps nor MicroG.

Can this help to solve that problem?

Any suggestion on what and how to better report this bug?

Kind regards

I'm having the same problem. I can't receive calls because the screen turns black and the phone becomes unresponsive.

Already set all the permissions to the calling app.

Looks like it is some problem with the proximity sensor.

Ok so I got a workaround to the black screen. Go to Developer Options, scroll down to Quick Settings Developer Tiles, and activate the Sensors Off toggle. Reboot the phone, then swipe down to show the screen where the control toggles are (where things like Wifi, flashlight, bluetooth, etc are). There will be a new tile called Sensors Off. Activate that, then the phone app will show the screen. The problem is that now you can activate things with your cheek. Also my received calls are totally muted my mic just stops working.

When I receive calls, speaker and mic are muted, but works ok if I make the call. Already tried other call apps.

Thanks in advance ?
[Samsung Galaxy J7 (2017) ROMs, Kernels, Recoveries] Alvin50:
Congrats!:highfive: At last the black screen seems to tear off! Despite I tried to follow your hints enabling Sensors Off in Developer's options, I am not able to locate the second tile you mentioned. I looked into "Phh Treble Settings", "Network and Internet", "Configuration Center", but didn't find it. Can you please detail that route?:)

Edit:

At last I understood what you meant...

It's not to search in the "settings", but to swipe down the very first status bar of the phone, the one in which is normally seen the battery and signal level!

Dragging it down, swiping it down, in the lower left corner there is a pen icon: tapping on it opens a lower screen where other services can be picked up and added to the first list, that grows to another screen to its right side. Sensors Off is the (greyed) lowest left icon, representing a barred resistor. After adding it to the main list it's possible to turn it on (turns to blue), and then it's finally possible to get rid of the damn black screen. HURRAH!! :good::good::highfive::victory:

I have to add that, in my SM-J530F I can make and receive calls and hold them. The installation is identical to yours, Havoc 3.5 + Ares. I shall make some more investigation on how I have set USB parameters because I'm not able to see the USB connected phone from PC, showing internal and SD memories as usual.

Havoc OS 3.5 Gapps Package Variant

Hello there Hacker, I've by God's grace finished installing Havoc OS 3.5 on my Galaxy J7 Pro. Thank you! I wanted to ask you about the Gapps package variant, "Stock", that you provided us with in that #opengapps.org website. Can I install "stock package"? and I also wanted to ask you, when i was in One UI Pie, I installed CPU-Z to check if my phone is ARM or ARM64. I found out that it's just ARM, and your Havoc OS is ARM64, but i proceeded with installing it and ended up okay. Should I choose ARM or ARM64 for my Gapps package after i installed your OS.

browsers freezing

Hi

Tell me, does everyone have a freeze in browsers (no matter what - chrome, opera or built-in)? It freezes for about 40 seconds, then for a while it works normally. Then, for example, follow the link or open a new tab, and again hangs.

I testified to this problem not only on HavocOS, but also on others, for example AEX. I must say I tried different kernels Kraken RC14 and Ares Kernel RC 02 and Cronos - there is only one problem everywhere.

I tried without root and with root. Without Gapps and with them.

I also noticed that while the browser freezes, if you scroll through the page, then after it stops freezing, the pages are at the very bottom.

You didn't "Detail" your operations.

please, be more extensive.

Suppose to speak with one that never heared of TWRP.

Like as if you were describing how to start driving your car: "I open the driver's door, seat on driver's seat, close the door, look if I have a good sight from mirrors..."

You can omit details of TWRP and Treble OSs installations, but, please, describe step by step what you do every time you want to make a full TWRP backup of a Treble installation. Then, step by step your TWRP recovery. A sentence says "Devil hiddens himself into details"... to look at a recent post, thalesv666 did a great discovery, but imho didn't explain it in a fool-proof way, and that's the reason of my detailed subsequent post, in which I tried my best to rewrite his finding so that it could be understood at first sight.
