[Completed] Android freezes while writing to /system - XDA Assist

Hey guys, I've got THIS going on.
I have a Samsung Galaxy J5 (SM-J500FN) running on stock ROM (a HUN Telenor one BTW).
I have rooted it, and I have TWRP on it.
OEM unlocked. No triangles at boot. Not even one-eyed ones.
Now, here comes the problem.
Whenever I try to copy write or edit files into my /system directory (and it's subdirectories) in any way, my phone freezes for 5-10 seconds, then IMMEDIATELY reboots. I can see the file I copied, but....
It's LITERALLY empty. Seriously, 0 bytes.
I replaced my bootsamsung.qmg with one I freshly converted from a .zip, same. Freeze, restart. At the boot, instead of my new bootanimation, I've got the "Galaxy J5" screen (y'know, "powered by android" etc. Also, yellow "Set Warranty Bit: kernel" in the top-left corner. Whatever.) STILL playing when the bootanimation was supposed to play.
And my phone doesn't respond for approx. 1 min. after the boot finished and the lock screen appears.
I cannot edit ANYTHING. I have my /system mounted R/W, I have permissions OK, root is working.
TWRP also happens to be unable to write, and I tried adb.exe on a Windows 7 PC tried to "push" the file (adb push C:\Users\ProtonPig\Desktop\bootsamsung.qmg /system/media/bootsamsung.qmg), with no errors. But once it finished, I looked at the directory on the phone and... - Guess what? Absolutely NOTHING!
Could someone tell me WHAT is going on, and how could I fix this?
Appreciating ANY kind of assistance.

[Q] Help with my Android Phone

About the phone:
1. I dont know the exact phone model, but it is Cloudfone Ice plus. There is a phone called Cloudefone Ice (Huwawei u8500) but i dont know if mine has another name.
2. It looks like this,
h++p://cdn2.sulitstatic.com/images/2012/0926/222830332_22162996997ba02ceb979675b8093b33516b3b725d6504ce0.jpg
3. Adroid version 2.2.1
4. Detected as "Globe Phone" in Google Play Market. *Globe is a carrier in our country.
The Problem:
When I turn it on, the android logo appears, and stays like that forever.
Cause:
After I tried to install a custom ROM using update.zip in recovery mode, the process got aborted in the last part of the installation.
5. I'm not sure if it's fully rooted, I have superuser but when I tried Root Checker before, it's not.
Other info,
I already tried to boot in recovery mode(it's the only mode that I get into now), I wiped data and cache/factory reset.(still stuck on boot screen)
I tried to install other Roms(update.zip), but all gets aborted in the beginning
I tried to download an update.app file in a dload folder in the root of sd card(firmware for huwawei)- I can't go to update firmware.I can only go to recovery mode.
I tried adb, I can use adb devices, it shows MT(serial number)
adb shell shows adb shell exec '/system/bin/sh' failed: no such file or directory exists
superboot cant detect the device.
I boot the device using power button+volume up,
when I use power+volume down, android logo appears and "Factory Mode" in the lower left (then It stays there forever, whatever button i press)
These are the infos that I can give, please help, I'm looking for fixes since yesterday from google and forums but no luck, nothing works so I decided to post my own.

[Q] Pls. modify system/app, ended with bootloop

you can call me a fool in this case
but anyway please help..
so please, hear my whole story first, so that you can examine the solution quickly.
my phone is: samsung W gt-i8150, rom: Liquid Smooth 2.9. build 3
first story. i wanted to replace the phone.apk with the one cm 10.1 own. so i copy phone.apk from CM10.1 zip file (that i got from arco official site). i wanted to copy it to root/system/app with X-plore root manager. but i cannot copy it even with superuser previllage.
second story. with no desperate to try, i delete phone.apk from system/app. then error message shown "com.android. bla bla not working". i dont remember whole message. i press OK, but the message keep showing up. can not get rid of the message, i decided to turn off my phone by holding power key. and after reboot, phone dont show signal bar, and of course, i can not make a call eventhough phone app could be opened.
third story. i'd remembered from somewhere, that i can flash apk with zip. then i decided to experiment a bit. i dont read any tutorial how to make update.zip (that's my fatal mistake.. my bad). i make my 'own version' flashable zip. making the original LS zip as an example. i deleted everything, and leave some that i thought important as you can see below :

}
The 'phone.apk' there, is the one i copied from cm 10.1 zip folder.
finally i install the zip via cwm recovery hope it'll work. i have seen your first paragraph LS instalation, but then it said "failed". and NOW, my phone ended with bootloop. it just stuck at samsung logo.
PLEASE,, how to fix this?? i dont want to re-install all over from the start... :crying:

Restoring the file should get it working as usual. If you don't just re flash your ROM. That's the only way I knit that will fix it. Or open your ROMs .zip. Locate the file and push it to your phone.

ok, I cant flash a new rom because i cant figure out how to connect unlock the boot loader. so where in the zip would be the setings.db file? so i can push it to the phone

I'm not sure, I don't own a lg.
Just open up a file explorer in your phone. Then just type in the search "settings.db" and it should should the file. Up the top it shows you what folder its in. Then just a find a ROM or stock ROM you're using then find it in that, then push the file to the destination in your phone using adb.

Maybe you use titanium to remove some development install. Here is it, on my phone

Need help for Nexus 7 2013 wifi

Hi everyone,
I bought a NEXUS 7 2013 (ASUS-2B16) a few days ago and I didn't like 5.0 so I started to downgrade by myself.
I followed the instruction of this page (I chose 4.4.2 (KOT49H) rom)
https://www.androidpit.com/how-to-downgrade-a-nexus
When I finished everything (I assumed everything went well because I didn't see any error message) and start to run the system, it stays on this screen
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",

"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
I thought 4.4.2 is not compatible so I flashed with 4.4.4(KTU84P) manually but with no luck.
So I tried Nexus Root Tool Kit see if I could fix it but again with no luck.
I started to do the research and I found this post from XDA
http://forum.xda-developers.com/showthread.php?t=2380913
The post description shows the same problem that I have so I followed the instruction until the step "FORMAT DATA in TWRP" then I am stuck again. IT shows an error message that the formation is failed.
After everything I gave up and I tried to follow this post to restore my Nexus 7
http://forum.xda-developers.com/showthread.php?t=2381438
Everything went well but AGAIN I am always stuck at loading page.
I started to look at details and I found some error messages as following.
First I found my Nexus 7 has no OS installed (I am not sure)
Secondly I found the tablet is trying to mount files from E drive but always fail.
I am totally a noob with Tablet but from my experience on Windows system I guess I deleted backup partition by accident. I am hoping this information could help you guys to help me repair my tablet. If you guys need more details please let me know. Thanks in advance.
Sorry, one more thing. When I enter the command "adb devices" at DOS mode I am not able to find the devices. However, when I enter bootloader mode my computer is able to connect to my tablet. Hope this could help. Thanks.
nobody can help ?

[Completed] Asus eepad transformer Marshmellow

Hey,
So this is my first foray into this sort of thing. I have some computer background but I haven't really gotten into this sort of stuff.
I have an Asus Eepad Transformer T101. I was requested to load Android 6.0 on it.
I followed this thread:
http://forum.xda-developers.com/eee-pad-transformer/development/rom-t3318496
I had to learn some things my way. User Debugging was on but I couldn't flash recovery. I ended up finally flashing recovery (I forget what step I had to do to use Clockwork Mod Recovery).
Once I was into CWM I had E:\Cannot Mount \sdcard\.
I then found out I had to use a micro SDcard, fine.
I couldn't load anything, and no solutions were working for getting SDcards to work.
I found a thread through google that said to use SD Formatter, to no avail.
Then I found this:
http://www.transformerforums.com/fo...x-bootloops-soft-bricks-all-ics-firmware.html
I have the files and. It was a batch file that loaded ADB then I could flash recovery. I attempted to flash recovery and I got to rogue XM recovery 1.5.0 (CWM - based recovery v5.0.2.8)
I used Nandroid Backup (Note, still could not mount SDcards)to do a backup of everything to the internal storage. I then did a wipe of all user data.
I have a folder called Marshmellow with Katkiss-6.0_025.zip, open_gapps-arm-6.0-pico-20160219.zip and BETA-SuperSU-v2.52.zip.
I attempted to install the KatKiss one, and it failed saying:
"Installing Update...
set_metadata_recursive: some changes failed
E:Error in /sdcard/marshmellow/katkiss-6.0_025.zip
(Status 7)
Installation aborted."
So here's where I'm pretty sure I screwed up.
I loaded the Gapps and SuperSU.
Tried marshmellow again, and no luck.
Now the device boots to the eepad transformer screen, lasts a few seconds (usually no more than 10) and then reboots.
I've tried
http://forum.xda-developers.com/showthread.php?t=1688012
and
http://justanotherdave.ca/?p=351
The latter simply doesn't work. And I don't think I can get into ABX mode for the former.
Are there any resources on how to "unbrick" the device that may still work. Right now it just keeps rebooting at the nvidia eepad screen. I can get into recovery still.
