I have a Samsung Galaxy J5 2017 with a broken screen, the screen is black and unresponsive. I found an app that I can use to mirror my phone screen to my PC so I can recover my Google Authenticator codes for my accounts which requires USB debugging to be enabled. Unfortunately I don't have USB debugging enabled on this phone, I found a few ways to enable USB debugging but none of them work for me. I can't use an external keyboard / mouse or go into recovery mode because the screen is black. I also can't use the screenshotting method because the screen is unresponsive. Is there a way to enable USB debugging using my PC?

I have a Chainfire-rooted Samsung Galaxy J5 with Android 7.1. The $PATH variable is /su/bin:/sbin:/vendor/bin:/system/sbin:/system/bin:/su/xbin:/system/xbin But /system/sbin appears not to exist at all. Why is this? Is it normal? Could the manual creation (and planned use) of this folder cause problems? (I run into huge ones, but not sure this was the cause.) --- *(I probably have made several mistakes, and I will post my questions one-by-one to avoid confusion. This is the first.)*

**The Iusse** ------------- Well, this is normally a simple task but I have a lot of problems. I hope you can help me. To begin, let's explain the situation: I have an *SM-J510FN device with firmware from Spain* to which, according to what I have been told, the unlock pattern was changed and the owner does not remember it, so he can not unlock the phone. ---------- **What I've tried** ------------------- **1:** The first thing I did was enter Recovery mode with Power + Volume Up + Home. After showing me the android icon looking for updates, I get a screen that says "Sin comandos" ("No commands") for a few seconds. Then the menu appears in which I choose "Wipe data / factory reset". When doing this, this message appears in red: E:format_volume: make ext4 failed on /dev/block/bootdevice/by-name/userdate with 1(I/O error) ---------- **2:** After this failure, I downloaded Odin3 (V3.12), Samsung drivers and a firmware from sammobile, the most updated with Android 7 for this device, which is not rooted (I say in case it has something to do with the problems ) I open Odin, I select the firmware where it says "AP", I connect the phone and start it with Power + Volume Down + Home, and the screen that says "Downloading, Do not turn off target" appears. In the log, odin says: Added!! I configure the options in this way: After a few minutes in which progress bars in Odin and on the phone are advancing, and messages appear in the log, Odin looks like this: Obviously, the phone restarts, but it does not start the system normally. Return to the Recovery menu, the same one that I entered to try de factory reset. Select "Reboot system now" and this time if it enters the system... but the same system, with the same unlock pattern. Nothing has changed. I tried to go back to the Recovery menu in case at least the error had been fixed when I tried to do the factory reset, but it was still the same, I have to say that I have tried the same with previous versions, even with Android 6 that is the one that comes from factory, but the problem is the same. ---------- **3:** I tried exactly the same as before, only adding Odin a PIT file for this device and checking the option of "Re-Partition", but the result is the same: Odin does everything he has to do without giving any error, but when it's over, the phone restarts and everything stays the same. ---------- I do not know what else I can try to restart this device. ***Any ideas?***

"Unfortunately, the process com.android.phone has stopped" error occurs when i try to change my network mode to LTE only. The phone i'm using is Samsung J5(SM-J500H).

## Context While trying to sideload [this LineageOS](https://forum.xda-developers.com/t/rom-10-arm64-lineageos-17-1-for-the-galaxy-j5-pro-j530-02-02-2021.4227945/) from [this link](https://androidfilehost.com/?fid=17248734326145727245) , on a Samsung J530F I'm getting the error: > E3004 This package is for device: j5y17ltexx; this device is . Normally that message can be used to indicate you are trying to install the wrong/an incompatible operating system on the phone. However, in this case the this device is . does not show what the device type actually is. And when I rebooted the phone into its original recovery mode, it said on top:

Phone type is:
j5y171texx/j5y171te.

So I think the lineageOS package is the right one for the right phone. ## Image with Error: ## TWRP version TWRP version is: 3.1.1-0 from the Team Win Recovery Project ## Question Why does the phone not indicate what type it is/how can I ensure the lineageOS file is installed anyways?

I dropped my Samsung J5 2017 in water. I tried to turn it off straight away but it wont turn off. I cannot access the battery as it is built in. My touch screen does not work and nor do the power buttons or volume buttons. Is there anything I can do?

I've got Samsung Galaxy J5 with Marshmallow 6.0.1 and in this phone I've got internal memory of 8 gb and a memory card of 8gb. I've stored every little picture and audio in external memory and many apps too but the system memory takes up 3.28gb and the apps take 3.83gb and there's no space left after that. I don't know what to do I don't even have many apps and games in this phone. Please help me on how to save up internal memory space without having to move everything to external memory?!!

I booted to TWRP recovery and tried to shrink /system and extend /data in the following way:

parted /dev/block/mmcblk0

(parted) unit s
(parted) print free

Then I removed last 3 partitions and resized /system:

(parted) rm 28
(parted) rm 27
(parted) rm 26
(parted) resizepart 25 3186687
 
(parted) mkpart physical ext4 3186688 3596287
(parted) name 26 cache
 
(parted) mkpart physical ext4 3596288 3602431
(parted) name 27 hidden
 
(parted) mkpart physical ext4 3602432 15269847
(parted) name 28 userdata
 
(parted) quit

Then you need to sync changes to be able to mount /system again:

sync
blockdev --flushbufs /dev/block/mmcblk0
partprobe

However, nothing is changed.

parted /dev/block/mmcblk0 print free

After mounting partitions in TWRP or after reboot to system the partition sizes remain old. What am I doing wrong? Has Samsung Galaxy J5 (SM-J500FN) any hardware lock?

I know it's difficult or rather almost impossible to change a 32 bit to 64 bit with or without root but is it possible to run 64 bit apps on a 32 bit Android smartphone without root access ? I am using Samsung Galaxy J5 Prime.

I'm running Android 6.0.1 on Galaxy J5 (SM-J500FN) and the main issue is disk space. If a system app is updated, old .apk remains on /system partition and the updated one is installed into /data partition. You may permanently remove useless system apps and free up space on /system partition, then convert user-installed apps into system apps using Link2SD. But after reboot all settings are lost because these apps are reinstalled again. When you update these apps again, old versions stay in /system and new are installed into /data. You cannot change this behavior, can you? I found another trick:

su
mount -o rw,remount /system
mkdir /system/xapk
mv /data/app/pl.blinkee.mobile-1 /system/xapk
ln -s /system/xapk/pl.blinkee.mobile-1 /system/app/pl.blinkee.mobile-1

You cannot make hard link between different partitions but you can make symbolic link. However, after app update, this link will be overridden and updated .apk will be installed into /data again. Workaround is to set up cron job that moves these apps into /system and makes symbolic links in /data. The best idea seems to repartition drive, shrink /system, extend /data. Any safe way to do it? BTW: What suffix -1 or -2 means at the end of folder name?

I have a Samsung Galaxy J5 and it isn't booting since I patched an app with Lucky Patcher (first time I tried it). I have had the root for some time, with no problems, but now I boot it and it goes black after showing the logo and 'Set Warranty Bit: recovery' for a second. I have a backup with Titanium Backup in my PC, and would like to know if I should **flash a custom ROM** I found for my device or **flash a stock version** (custom ROM works for everyone and comes with instructions, but I don't trust so much the stock version). Also, the custom ROM has a lot of steps, but there is no cyanogenmod version for the J5. Thanks in advance! (also, is there any other solution?)

I get "Internet may not be available" on my new Samsung J5 Prime around every 5 minutes. This did not happen with other Android devices on the same Wi-Fi router. What can be the problem? Model SM-G570M Android 7.0

I bought this brand new Samsung Galaxy J5 yesterday, but I'm stuck with an internet connection problem. The thing is that the WiFi connection worked properly on the store and at some other places, but in my home, it connects to the WiFi but I don't seem to have any network (I open the browser but can't access any URL). All others devices that I have in my house work very well (other Android devices). I'm assuming then that : 1) The J5 is working properly (as I can connect it at other places); 2) The WiFi in my home is working properly (as others devices connect to it *and* can access any URL). I was digging many hours yesterday on the web to find a solution for this but nothing has worked so far. By the way, all "J's" devices seem to have a lot of these issues. Is it correct to say that I may be facing some kind of compatibility issue, between J5 and my WiFi? If yes, what could I do to solve it?

I have a Samsung Galaxy J5 2016. It's gotten extremely slow and buggy (>10 crashes a day, waiting more than 30 seconds to open default apps, ...). I've done a factory reset, with removal of all data, including SD card. And... It's just the same. I'm already looking around for a new phone, but I'm wondering what can cause this? When I google why phones get slower over time, they point to more and heavier apps. But this doesn't explain my case. What can cause this behavior, even after a reset?

I removed my phone battery when the phone was on without turning it off first, my SD card was encrypted, so now I cannot access my SD card contents on my phone while phone detects the SD card. Moreover, when I turn my phone on, encryption page shows after boot, giving me the option to encrypt or decrypt the sd card and selecting either encrypt or decrypt won't do anything. So how can I decrypt my SD card and access my data? My phone uses android version 6

My phone origin is the UK and I am in Sri Lanka now. My phone modemst1, modemst2 were reset and also I forgot to backup.

dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst1

dd if=/dev/zero of=/dev/block/bootdevice/by-name/modemst2

After reset it has asked to unlock the network. I've tried many solutions such as flashing stock ROM of UK before I had custom rom(arrow os), zx3 tool pro. I could not do it. I don't plan to buy a code since I think, It can be recovered. I think it can be done via modifying the CSC file since it is specific to geographical region and carriers and it contains the software packages specific to that region, carrier branding and APN setting but I don't have enough knowledge to modify the CSC file. Another possible solution may be flashing the living country CSC file but I could not find CSC file only for my j5nlte phone with Sri Lanka. Can anyone suggest how to modify the CSC file or **provide any solutions to unlock the network in my device**? Thanks in advance.........

I want to recover user data still on device memory on a Samsung Galaxy J5 2016 that won't start. When i try to normally boot up the phone it goes to the model screen and then switches to a screen animating the samsung logo once and then continues with pulsing brightness. It stays like this seemingly forever while the battery is running hot. During some research i stumbled across the wording "boot loop" but i'm unsure if this is appropriate, since it is not shutting down and restarting. I'm able to access the recovery menu and tried the "wipe cache" option and tried restarting without sim/sd card which both did not help. To clearify my intentions: i want to recover left over user data left on the phones memory (not on sd card). The hardware itself will be dumped afterwards, so resetting to factory state would not help in my case since it would delete user data. (Or am i wrong at this point?) If, for example, a desktop crashes, you could still reboot from an other drive and access the harddrive with the faulty system. So might it be possible to boot something else up on the device without touching the existing system. Notably the device is unmodded. It has never ever seen the development settings, no USB-Debugging, no OEM-unlock. So flashing will not be possible from what i've read. Funny (or frustrating) enough that samsung devices softbrick on their own. Whilst writing this question this thread popped up in the suggestions with astonishing similar symptoms though in that case, as in all other articles i read, the problems were caused during tinkering on the device so that the oem-unlock already happened and a new recovery was already flashed on, which, as mentioned previously, is not the case here.

I have a rooted Samsung Galaxy J500F. Trying to get more storage, I moved all of the system files to the sd card and now the phone won't turn on. The PC will not recognize the phone (no ding, no device manager detect). Not able to get into recovery mode. Im not able to charge the battery either. How to recover a phone in this condition? I used two JIG's (one I bought and one I made) it didn't work. I have downloaded the firmware but I can't flash the phone (or can I?).

Move installed apk from phone memory to sdcard on android 6.0.1 without root and install new apk to sdcard. My device is Samsung Galaxy J5 (SM-J500H os updated to 6.0.1). Phone's memory is too small to use install big applications and games. I installed asphalt 8 but cache files are too big for phone memory. What can i do?

### What I have: I have a Samsung J5 (2015) SM-500FN which ran out of storage and basically hung itself up. There is no data I want to recover, but I want to install either a stock ROM or (preferably) something else like Lineage - I just want to get a usable phone again. ### My problem: 1. I have tried to download *many* stock ROMs from reputable sources like SamMobile (for this specific phone , but trying different release dates and country codes) but every single one of those ZIPs is corrupt, even when downloading from a different computer. 1. Flashing with ODIN anyway gives a FAIL result and a device that cannot boot, not even into recovery: It gives a green screen with the text: An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch PC software. 1. Ironically, the Smart Switch software just says this device is not supported. The older Kies3 software lets me enter the exact model# followed by the serial# - but then it says this device is not supported. So neither Samsung software is usable, but I can still use ODIN. 1. Even with the phone in this broken state, I can install TWRP again. So it is not completely bricked. I boot into TWRP and copy a LineageOS ZIP file to /sdcard, but when I try to install that, the TRWP console says: E3004: This package is for device j5nlte,j5nltexx; this device is . Note it doesn't appear to recognize that this device is indeed the model j5nlte! 1. Android.SE says that "E3004" means my TWRP is too old, but I use twrp-3.1.1-1-j5nlte which is currently the newest version for this phone. 1. I would also like to try a factory reset, but that requires the stock recovery which won't boot (see step 2 above). ### My question: How do I get out of this catch-22? It seems that if I could just get around that E3004 then I would be fine. But I have found no ways to trick the installer into ignoring that error.
