[Galaxy S6 Q&A, Help & Troubleshooting] Frankbrazillian:
Maybe you are trying to install an wrong firmware.... Are you sure, your phone CSC is ITV? In case If you buy this phone from third parties. If you are flashing the stock firmware with Odin and stuck at boot logo, I believe something is wrong. I 'm pretty sure your issue is related to dm-verity verification. Like I said, in my case, If I try to flashing any custom rom, I got the dm-verity verification failed on recovery. The signal bars appear on the status bar, but I can't make calls because I have no service. Flashing the stock (untouched), no problem. Sometimes the problem is much more simple than we think. Hope you find an easy and cheap solution. Good luck!
[Galaxy S6 Q&A, Help & Troubleshooting] brenner650:
Phone is from a third party, and was stuck at logo when I got it.

I assume phone CSC is ITV, because that is what Smart Switch flashes via emergency initialization.

Is it possible I made a wrong assumption, and for some reason SS is flashing wrong fw?

Anyway, even with Xtrestolite rom, the issue remains.

DM-verity verification fail appears to me too, right after 1st reboot, after flashing.
[Galaxy S6 Q&A, Help & Troubleshooting] Frankbrazillian:
Reading your first post again, i notice you already posted all info there. Have you tried to install the stock firmware for the carrier you are trying to use and wipping the data and cache before or after? Maybe the problem is not with the device, but with the carrier you are trying to use....
[Galaxy S6 Q&A, Help & Troubleshooting] brenner650:
I did.

Browsing this forum I found out that there was a similar issue on S3, I think, which was solved with ariza patch, too bad there is no such thing for s6.
[Galaxy S6 Q&A, Help & Troubleshooting] Frankbrazillian:
Why you don't contact the dev who create this patch? Maybe he can help you....

wrong
[Galaxy S6 Q&A, Help & Troubleshooting] brenner650:
Well, after fixing with that guy`s box 98% of calls were lost or unable to place, so if you ask me I wouldn`t bet that he has done things right.

SN of the device turned to android sn, it showed up in about the phone, only after I wrote it to file in EFS folder.

Unfortunately I don`t know anyone else with a box here in Prague where I live, so cannot give it a second chance.

[MENTION=5440239]Frankbrazillian[/MENTION] unfortunately developer of that patch for S3 was last time logged in to the forum over two years ago.
[Galaxy S6 Q&A, Help & Troubleshooting] Frankbrazillian:
Sorry to hear that. I'm still trying to figure it out, about this issue. I have worked with a lot of japanese Samsung device, building custom rom's, but its the first time I see this. If I figure it out, i'll let you know. Good lucky!
[Galaxy S6 Q&A, Help & Troubleshooting] brenner650:
Thx, I keep my fingers crossed, cause I couldn`t find a solution in last four months.

I posted link to bug report if it is of any use on page 6, and if you need any other info I will gladly provide it.

Saw that there are couple of more people with similar issues, and no one found a solution so far(except motherboard replacement), so if you find it I`ll buy you a beer. :)

If not, motherboard replacement, it will be..
[Galaxy S6 Q&A, Help & Troubleshooting] brenner650:
Out of curiosity flahed cm13 yesterday, but nothing changed, still NO SIM, and phone SN turned to what is shown as android SN in phone info, so I am guessing that there could be the issue probably.

Mobile networks menu is shown in CM, but it is greyed out.
[Galaxy S6 Q&A, Help & Troubleshooting] brenner650:
Update:

- during last Smart Switch emergency initialization phone serial number changed by itself, and no longer is as it is on back of the phone.

-DRK repaired by [MENTION=7253997]Guardian of the Galaxy S5[/MENTION], phone booted for the first time without any custom kernel

-however IMEI was reset during process, and baseband turned to unknown.

-after several reflashed firmwares, bootloaders and modems, downgraded to 5.1.1 BTU (phone original CSC is ITV according to Smart Switch), and baseband is fine now.

to be continued...
[Galaxy S6 Q&A, Help & Troubleshooting] brenner650:
Thanks to [MENTION=7253997]Guardian of the Galaxy S5[/MENTION] who let me use his Octoplus box, new cert written and IMEI fixed.

However no SIM issue still present, so I guess unfortunately it is a hw issue :(
[Galaxy S6 Q&A, Help & Troubleshooting] brenner650:
What do you mean by averaging the service menu?

Also the link is broken (404).

I had no issues with pit, but I flashed pit with 5.1.1. BTU fw few days ago, just incase, had no issues to flash 5.1.1 ITV afterwards.

Got advice today to try OTA update, but that also didn`t change anything, after successful update, still no sim detected, and before that I flashed stock 5.1.1 ITV fw via Odin.

I also have both:

ITV (5.1.1+6.0.1) + ZEROFLTE_EUR_OPEN_HIDDEN60M.pit

BTU (5.1.1) + ZEROFLTE_EUR_OPEN.pit,

and also have converted 5.1.1 ITV fw to .oct file yesterday.
[Galaxy S6 Q&A, Help & Troubleshooting] brenner650:
Well I am not sure which settings should I touch, and all sim related options are unavailable due to no sim :/

I guess it would help if I`d have seen service mode of a working phone :D
[Galaxy S6 Q&A, Help & Troubleshooting] Androidps3:
Is your phone unlocked or carrier locked. Try factory reset/cache data wipe. Then contact stifilz2@gmail.com???. Sprint s6 on tmo
[Galaxy S6 Q&A, Help & Troubleshooting] brenner650:
Service mode says it is unlocked.

Factory reset/wipe data/cache I tried many times so far, with no results.

To contact him for what, service mode settings?

I am in Europe, I think here are different bands used than in USA, so I guess that settings could also be different.

Please correct me if I am wrong, I know only pure basics of gsm networking.
[Galaxy S6 Q&A, Help & Troubleshooting] Androidps3:
Thts who unlocked my phone. No root. System update caused me to lose it i thnk. He unlocked it again. Idk how to back up my efs. But no problems wit phone.
[Galaxy S6 Q&A, Help & Troubleshooting] brenner650:
Well last time I flashed 5.1.1. BTU fw, I flashed it also with a ZEROFLTE_EUR_OPEN pit, and after flashed 5.1.1 ITV just fw, without pit, without any problems, so I am guessing that they both use same pit, please correct me if I am wrong.

Sure, we can try that when you will have time, I would apreciate it, but still I somehow feel that it is high probability of SIM reader malfunction, or some cold solder, after all I have tried. :)
[Galaxy S6 Q&A, Help & Troubleshooting] RaySteel:
I have quite the same issue.

I was using my S6 G920F nearly for a year (LP5.1.1., Root, XPosed, WanamLiteROM) very much and happily. So I decided now to buy 2 other new ones and restore a full TWRP Backup to the both new ones. It seems everything was alright, till I put Nano-Sim into them and try to use phone and mobile data :(

I also tried everything from above within this thread.

In the moment when the EFS was overwritten (with wrong IMEI/Serial) the DRK (Device Root Key) was changed (I think it is similar to the Know-Counter).

Everything seems fine (with settings-about phone or Phone Info app) when I flash the latest stock firmware (via Smart Switch or Odin 4piece-FW with Re-Partition ticked) and flash the SpaceX RC2.1 ROM, Xposed Framework and IMEI changer...but I can´t use phone and mobile data yet :(

Sure, in the last few days I learned that I must backup the EFS just after buying a phone, but actually I have only the backup from my old one :(

I live in Germany in the near of Düsseldorf, who owns the Octoplus Box and can help me ? (I don´t think that it is possible remotely via Teamviewer)
[Galaxy S6 Q&A, Help & Troubleshooting] gwest04:
Yes

get an octoplus back up his stuff. Read security, read efs, read cert. Good luck
[Galaxy S6 Q&A, Help & Troubleshooting] brenner650:
First I apologize to everyone for longer post.

After a long time of messing around with Octoplus box, by various people, myself included, writing different certs I decided to replace SIM reader (Ofc. IMEI in the phone was different, than on the back of the phone).

So I went to one 3rd party repair shop in Prague, Czech Republic (where I live), which wanted me to sign that if the back glass is broken during procedure, it is not their fault (ofc. they would be so kind and sell me replacement glass, and charge the replacement), so I took the phone and went to another.

Some Russian 3rd party repair shop, in which they told me a story I heard a thousand times before, that Samsung blocked my phone, and was jabbering something about iPhones and FBI and who knows what (low level English speakers, so I didn`t understand much, and frankly, didn`t even care).

Decided to spare myself some time, and tried to contact few more repair shops to change SIM reader, but somehow didn`t manage to find anyone who would do it here.

So I decided to bring phone with me to Croatia (where I was born) for Christmass holidays, and while I was there, in between of Christmass presents shopping, decided to stop by authorised Samsung repair shop.

Left the phone there, said there is no warranty since I bought it from the ad on the web, and after two days, when I called them, lady on the phone told me that they are waiting for spare parts from Samsung (SIM reader, and, you won`t belive it, back glass plate), and in case of repair price evaluation, I will be contacted by them.

Also she pointed that I can check their web for repair status.

Thinking, ok, guy who was opening the phone smashed the glass, and since the price was still 0 on the web, they will replace it on their own cost.

Who knows, maybe some young technician is practicing on my phone :D

Yesterday, I checked the web and was really surprised to see that complete motherboard was changed FREE of charge (in Samsung service center in Prague they wanted to charge me more than a completely new, unopened phone costs on the web ads + charging module + backpanel glass.

Phone is now on its way to Czech Republic from Croatia, and will be here in few days. (my gf`s brother picked it up and sent it to me)

I still cannot belive that after almost a year, and lots of lost time, some little amount of money, and a ton of nerves, the phone is, and I quote: repaired, and working as designed by manufaturer`s specifications.

Can`t wait for the phone to arrive here, to see it with my own eyes. :D
[Galaxy S6 Q&A, Help & Troubleshooting] Brontok:
I`m glad they fixed your phone. I had a similar, if not the same case with my s6. Bought the thing with 5.1.1 installed, took OTA to 6.0.1 and the phone got stuck in bootloop with "drk verification failed" message. The guy who sold me the phone flashed it several times, but never made any efs backup. So I was stuck in the same situation as you. Managed to boot it, but it couldn`t accept sim cards. Long story short, a guy with a z3x box "fixed" it. The phone was able to register on a network, but the signal bars would drop from time to time. And the UI was often laggy. The phone would be fast, and then suddenly stop completely for a few miliseconds( just froze the entire picture, whatever was on the screen at the moment). The thing is, I had no efs backup, my imei, sn, and baseband were corrupted. He told me not to flash anything, or the phone will die for sure. He was barely able to get it to work (spent several days trying). One more thing, the way to see if your efs is corrupted is to connect to a wifi network, disconnect, and try to see if the phone will connect again. Mine couldn`t connect for the second time. Each time I had to enter the wifi password. Backup people, or even better, stay away from flashing, if you own a samsung device. :)
[Galaxy S6 Q&A, Help & Troubleshooting] brenner650:
I agree with you, but what is weird is that in Croatia factory warranty was accepted, no questions asked (knox was tripped and IMEI changed), even if I told them that I don`t have any warranty, and in Czech Republic in official Samsung repair center, they wanted to charge me 355 $ for a new motherboard.
[Galaxy S6 Q&A, Help & Troubleshooting] wilksy1:
All they did in that authorized samsung repair shop in Croatia was break your back glass opening the phone, and then realized they cant repair a carrier blocked motherboard and then replaced the glass back for free and said come get it, its working, they didn't replace the motherboard with a new one on a rooted security tripped phone with no warranty for free, no one believes that
[Galaxy S6 Q&A, Help & Troubleshooting] wilksy1:
they didn't replace the motherboard for free on a no warranty, security tripped, rooted, carrier blocked phone, no one here believes that, they just replaced the back glass they broke and said its fixed, u need to buy a replacement motherboard and do the repair yourself,it's easy.
[Galaxy S6 Q&A, Help & Troubleshooting] brenner650:
Sorry for the late reply and raising the topic, no need for me to repair anything, phone works fine.

I am still using that phone, and Knox is no longer tripped since the repair.

Phone is full stock, unrooted and with new IMEI. (you can see it has been flashed to hell and back in the previous posts (and only god knows what did the previous owner do))

And yes, they did replace the motherboard and back glass. ;)
[Fire TV Q&A, Help & Troubleshooting] cybrid3:
Hi guys, wondering if you can help me. I have a firestick, its the voice control one. Its not rooted and is stock. I installed FireStarter on it but now its unuesable. Everytime I boot it, it says loading home but never does, it then goes to network issue but the remote does not work. I am not able to do anything. I want to be able to hard reset it but without the remote I cant do anything. I cant ADB via network as its not connected. I can plug it to a PC and it shows USB. The screensaver eventually comes on. I have changed the batteries in the remote but no joy. Can anyone shed some light please?

You probably already tried this but in case you haven't you have to hold the home button sometimes for a really long time for the fire stick to pick up the remote. I had to do that for a fire stick I was setting up, it took a long time holding home button but eventually it paired the remote.

[Fire TV Q&A, Help & Troubleshooting] firesticktv:
hi,

If you have adb debugging Enabled on stick,

you can connect the stick on usb PC , and you can send adb command and move into stick Menu settings with adb command:

http://www.aftvnews.com/how-to-remotely-control-an-amazon-fire-tv-or-fire-tv-stick-via-adb/

For adb drivers on Windows PC , look here :

http://www.aftvnews.com/fire-tv-stick-usb-port-not-for-power-only-adb-over-usb-confirmed/

use Moborobo.

Or if you on a Mac/ PC Linux , just open a terminal

and send adb command.
[Fire TV Q&A, Help & Troubleshooting] cybrid3:
Tried all that. Is there a way to flash stock firmware via adb?
[Fire TV Q&A, Help & Troubleshooting] firesticktv:
but can you send adb command via usb/PC?

If yes, you can move into amazon settings with adb

command to On bluetooth or connect wifi or reset factory ..
[Fire TV Q&A, Help & Troubleshooting] cybrid3:
I have tried to toggle WiFi and Bluetooth but no joy. Do you know the adb commands to factory reset?
[Fire TV Q&A, Help & Troubleshooting] firesticktv:
i think you can't launch factory reset via adb on firestick.

And command: svc wifi enable on did nothing?
[Fire TV Q&A, Help & Troubleshooting] cybrid3:
nothing. cant do anything with it
[Fire TV Q&A, Help & Troubleshooting] firesticktv:
but if you send via adb:

adb shell am start -n com.amazon.tv.launcher/.ui.SettingsActivity

Can you see the amazon Menu settings ?

I don't understand why you can't do this if you can

connect via adb/PC to go after with

command adb shell input keyevent xx in menu to launch factory reset or reconnect wifi ...
[Fire TV Q&A, Help & Troubleshooting] cybrid3:
I can only connect while it is plugged into the PC. So I am unable to see anything. When it's plugged into hdmi nothing at all works.
[Fire TV Q&A, Help & Troubleshooting] firesticktv:
ok :( i will try if i can find a soluce via adb..
[Fire TV Q&A, Help & Troubleshooting] firesticktv:
Ummm, If you take screenshot via adb command ,

you can see where you are in the Menu settings

to gradually move to change/launch what you want

with input keyevent xx ..

After stick is connect via adb/PC

1) take a screenshot to verify what appears on amazon Home

2) Launch Menu settings with adb command

adb shell am start -n com.amazon.tv.launcher/.ui.SettingsActivity

3) Take a screenshot to verify Menu settings appears on screen

4) if it's good , use adb command input keyevent xx to move accross Menu settings and take screenshot to verify your move.

Adb command for screenshot:

adb shell screencap -p /sdcard/filenameXX.png

### pull screenshot to windows pc in c:\

adb pull /sdcard/filenameXX.png c:\

Now you can open filenameXX.png in c:\ to watch firestick screen and verify what you do on it :)
[Fire TV Q&A, Help & Troubleshooting] firesticktv:
Ok , sorry for last post , screenshot via adb is not working if the stick is not rooted ...

So , i have try to connect my firestick to my laptop port usb

and plugged into tv hdmi and adb command works !!!

So i can send adb input keyevent xx to move and watch

where i am on the Menu Settings ...

How: (windows 8.1 laptop)

1) plug my Firestick to Pc/Usb and to Tv/hdmi ( booting on amazon Home screen )

2) Download/ install google drivers:

link drivers:

https://dl-ssl.google.com//android/repository/latest_usb_driver_windows.zip

And follow instructions here to install drivers:

http://www.jocala.com/usbdriver/

3) Download/install adbfire for windows

http://www.jocala.com/

4) Just Launch adbfire ( see my serial firestick in connected device)

And click on button 'console'

5) it's open a Dos Windows and i can send adb command and watch my firestick amazon screen on TV.

6) i send command to verify : adb devices ( i see my firestick)

i launch Menu settings:

adb shell am start -n com.amazon.tv.launcher/.ui.SettingsActivity

and i use adb input keyeventXX to move ...

Link :

http://www.aftvnews.com/how-to-remotely-control-an-amazon-fire-tv-or-fire-tv-stick-via-adb/

So you say you can send adb command but not when the

firestickTV is plugged in hdmi ..

Its works via hdmi !! so i can't help you more...

Perhaps can you retry with my instructions here...

You can easily reconnect wifi/ pair your bluetooth remote but for launch a factory reset , i don't know if you can because firestick is connected on PC/usb port and can says error power problems ...

Hello,

I have similar problem and trying to learn how to get my stick working.

How did you connect Fire TV Stick to your laptop? Did you use HDMI to USB convertor?

Thanks,

Apur
[Fire TV Q&A, Help & Troubleshooting] harlekinwashere:
HDMI is for video/audio out only. if you are thinking about connecting it to a laptop to watch movies on it - you cant. Most laptops don't have video in connectors.

If you wan't to connect the Fire TV Stick via a data connection (basically to troubleshoot, install stuff, poke around in the file system - you always do that via its USB port. Or wirelessly - having adb debugging enabled in the developer options.

If you have issues getting adb to connect to your device, especially wirelessly - toggle the adb switch in the developer options off and on again (only one remote adb connection is allowed at a time - sometimes the channel is "busy" already - togling it off and on a again "clears" it). If you still have issues - its most likely a networking problem. Usually, that you don't know much about networking.. Or adb. But you can learn that.
