Terminal which comes with CM13 does not allow me to ping ip's and websites.

I keep getting socket permission denied errors or unknown host errors.

I simply type "ping google.com" and it gives me "unknown host google.com"

A separate ping app can ping google and ip addresses no problem.

Why doesn't Terminal work?

I am also having the same issue, the focus doesn't work, neither manually nor in auto mode. Sometimes, just sometimes, it luckily does work, but most of the time it doesn't.. i dont understand what the problem is..

Recently, the camera was acting way weird, like showing dark picture with green lines, and sometimes it wouldnt even open, it showed just a black screen, i cleared data of gallery and camera, which resolved the issue, but still void of ability to focus. :(

I've been on a quest to find a rom where the wifi works. Every wm6 rom I've used, wifi shows the APs, it connects then disconnects soon after and the AP says unavailable, then it'll work again for a sec then disconnect. I read somewhere that a rom based on build 318 would work and someone gave the XDAr6 rom as a suggestion. Same thing. works fine in every WM5 rom, just none in WM6. Anyone have an idea why? Maybe I'm missing a step to get it working or something?
[8125, K-JAM, P4300, MDA Vario ROM Development] elcanela:
Hello. Install Battery Status, (I have version 1.04.203.beta4) and it has several tabs, one of which has a checkbox that disables the proxy if WiFi is enabled. I ran into this issue too when i first started playing with new ROMs, and was very frustrated until I found this nifty app, and best of all, it works with all the ROMS I've used. Enjoy, hope it helps.

I don't know why this fixed my Wi-Fi, but it did. I just got this phone a few days ago and I was having trouble since yesterday getting the WLAN to enable. I would click it in Comm Manager and nothing would happen. Something I did broke it.

Of course it still won't connect and says "Unavailable" whenever I try to connect to anything that was just a second ago "Available", but at least it's back to the way it was when I got it. :)

Try this when you get a chance...

Go into your registry and change the following settings

HKLM\Comm\TNETWLN1\Params

HTCPreloadStatus = 1

HTCPreloadWifi = 1

This solved my issue I had with Wifi after I reflashed my device a couple times to various WM6 ROMs.

For some reason the HTCPreloadStatus never sticks and always converts back to zero. But I was reading a thread and found this solution and it said to do both reg edits. The fix did work for me so I didn't question it.
[8125, K-JAM, P4300, MDA Vario ROM Development] endolith:
Mine says "Available", then I enter the network key, and it says "Connecting" and then changes to "Unavailable". It has done this since I got the phone. Today I unlocked it all and upgraded to the latest T-Mobile ROM, and it still does this. I guess I'll keep going and upgrade to a WM6 ROM, but I'm afraid it still won't work then.

Quick facts

Exynos bootloader is unlockable, which is why we won't talk about that here!

S7 Variants https://en.wikipedia.org/wiki/Samsung_Galaxy_S7#Variants

US & China use a Snapdragon processor, all other locations use the Exynos

Knox counter: will void warranty (if you still have one!) Most could careless if there's a remote possibility of unlocking the bootloader. Methods or tampering could possibly trip this counter.

Mostly when people say a phone is "locked", they mean locked to a CARRIER. That is NOT what we're talking about here - we're talking about a locked bootloader which allows you to install a custom ROM.

Locked bootloader

Easy way to tell you bootloader locked status(?)

What is the bootloader? Part of the Android boot process. See all about it here: http://newandroidbook.com/

Why can't we currently unlock the bootloader? There is something called the chain of trust, whereby 'everything' from when the phone first turns on, through each 'piece' it verifies the contents of the flash is legit and from a listed trusted source (either Samsung or carrier). What controls this is the current, existing software/FW on your phone. So if we took what's there and removed these checks, we currently don't have a way to write this to your phone, since "we" aren't from the list of trusted sources. How do they enforce this? The images need to be digitally signed.

What does it mean to digitally sign a file (or image, FW in our case)? There is a private key and public key. Samsung and/or Carrier have the private key, your phone has the public key. Author writes a new SW package, then uses a tool to get a checksum. The checksum gets encrypted with the private key. The encrypted checksum gets appended to the SW package. Using OTA (over the air deployment) or ODIN, we push the package to the phone. The phone decrypts the appended encrypted checksum using its public key, does a checksum on the remaining package, and makes sure they both match. Now you can see why we can't fake this! Only way would be to find an exploit or get the private key so we can sign these ourselves!

Unlock Methods

High-Level Ways to Unlock:

Get leaked private key so we can sign our own images

Find exploits

Dev bootloader gets leaked

?

What does work:

Can flash digitally signed images

Can write to partitions with engineering kernel

Ideas:

Use engineering kernel that has root to somehow modify bootloader partition to remove digital signature checks - at level/entry point can or should this be done? (ie, where in boot process at a minimum do we need to remove the check?)

Attempted Methods:

OEM Unlock in Android Settings menu: YES! We tried that!

Flashed Chinese images via ODIN. People used PIT (Partition Information Table) files and checked reformat partitions in ODIN and still failed.

Result: Errors during flash process, won't take, "Thread Failed" error

Chinese bootloader is v2 where all US models are v4(? How to determine?)

Convert Chinese ROM to another variant: https://xdaforums.com/android/general/guide-how-to-convert-chinese-roms-based-t3577469

Use CROM app (Chinese phones have this app to unlock their phones):

Result: This app communicates to Samsung servers and ends up writing a flag (kiwibird?) to STEADY partition. US phones dont have this partition so this currently wont work.

Where are you finding a "BL.mdf" file? I'm looking at stock images and see mostly mbn, bin, and img files. Is this an extraction of one of these files, images? Not sure this will help but here they talk about "brushing" (flashing) 'pick and choose' images making a compilation for a full flash (like pick US modem, with chinese bl, etc) & the Chinese are successful using US "pieces"/images despite having a different phone variant https://xdaforums.com/verizon-s7-edge/how-to/g935v-cross-bootloader-flash-chinese-t3432190 Another possible way could be the opposite of what you're trying: implant the international device ID on our phone so the image can flash without your error. (via engineering kernel possible to change this value, wherever it sits?)

Also, another thought: I wonder if there's a way to modify the PC ODIN tool (or Heimdall since that source is easily available) to add functions to talk to "hidden functions" on ODIN (on the phone) to unlock it that way. Or modify it to turn it more into an interactive console so we can navigate and investigate the phone's ODIN program. Does anyone know if the ODIN source for the

phone side

has been leaked? If not, any intelligent folks out there know how to 'reveal' all methods so we can go through it and maybe find exploits? (This been done already?)

One more thing: Those thinking the S8 is nearly out now so let's give up... Well, can anyone predict the future like I can?!! I'm SURE it will be locked as well. I wouldn't be surprised however if any exploit we can find for the S7 will be relevant on the S8!

I'm not sure what's accurate. And Does ODIN/bootloader allow you to go from Nougat to Marshmellow? Knowing this will help with our unlocking methods...

[Samsung Galaxy S7 Guides, News, & Discussion] Chillstice:
I have a rooted SM-G930v using the engineering kernel, but I find the limitations of having a locked bootloader hyper-frustrating. In fact, I started researching which non-samsung android phone will be my next. (Looking at the Huawei P10/P11). I've been trying to use Magisk, TWRP, and a few other tools and have come to the realization that none of these are possible with a locked bootloader. Why is it that the Chinese variants have unlocked bootloaders? Samsung surely didn't make the decision to lock down their devices. It must be the US carriers that insist on locking down their devices and systems so that people can't modify certain apps, systems, and roms. Like bloatware for example. We just can't have nice things.

I wish I had more time to work on this, but I am not very experienced and I would almost rather get a similar device that is easier to root. I will however follow this thread and contribute what I can.

Folks,

I really need your help.

I bought p9000 a week ago, and did the standard upgrades via OTA.

I read about the Android Nougat version, and I decided to install via Flash Tools, however, due to the various bugs, I decided to go back to Marshmellow version 6.0.

The problem happened after I used the flash tools, it simply bricked.

The process happened correctly, but it just does not start.

I read in other forums to try to remove the plug from the battery, and so I did, but did not solve anything, my computer simply does not recognize the device.

I use Windows 10 x64 ... Please, anyone know how to recover a braided device?

I used the Nougat version bootloader, and I connected the phone.
