[Samsung Galaxy S7 Edge Questions and Answers] bobbaker1970:
Many thanks that sounds like an interesting idea.

But.............. if I go back to the first version of 8.0 (oreo) will it wreck Knox or anything else to do with security. I want to still be able to use samsung pay for example.

Also, i was told by a samsung shop person that you can't downgrade because there are systems in place to stop you. Though i dont know if he meant from 8 to 7 or from recent 8 to older 8.

I am planning to flash this:

https://www.sammobile.com/firmwares/galaxy-s7-edge/SM-G935F/XEU/download/G935FXXU2EREM/222561/

due to fact that its original software was xeu. Is that ok?

Your help was very valuable thank you

Bob
[Samsung Galaxy S7 Edge Questions and Answers] rroyy:
you wont break the knox and you don't have to go that much back just download 2 version back from january or february will be enough.

you can't downgrade your bootloader or turn back to android 7.0 that's what they mean. Smart Switch shpuld fix the problem for you.
[Samsung Galaxy S7 Edge Questions and Answers] bobbaker1970:
Many many thanks again Rroyy

Forgive me but I am new to this.

So are you saying:

1. Download:

https://www.sammobile.com/firmwares/galaxy-s7-edge/SM-G935F/XEU/download/G935FXXS3ERLF/251612/

That's the last but one from January 19.

Which has: PDA	G935FXXS3ERLF

CSC	G935FXEU3ERKF

2. Can I just flash that. Or must I remove the bootloader from that package and put in the current bootloader?

And I was presuming I would do all of that with Odin??? Am I wrong. Is there a way of doing it with smartswitch? (I have reset the phone and got rid of all of my information already)

update: tried flashing last rom , that didnt work. the one before wouldn't flash - i notice it has numbers'3' in the various codes rather than 4.

still not solved

Many thanks again

Bob
[Samsung Galaxy S7 Edge Questions and Answers] rroyy:
Flash the os via odin (select CSC file not home CSC) Untick re-partition option on odin. (Instructions)

Select all files except home_CSC from odin. BL-CP-AP and CSC

After your device boots, skip settings till you see the home page. Connect your device to pc and launch smartswitch (It could ask you to install smart switch to your device) and update latest firmware over smart switch.
[Samsung Galaxy S7 Edge Questions and Answers] bobbaker1970:
Many thanks again Rroyy

Unforunately, I am getting nowhere. And cannot get my phone to work.

Odin will not let me flash any files which have '3' rather than 4 in them. For example I can flash

BL_G935FXXS4ESC1_CL14843133_QB22373776_REV00_user_low_ship.tar.md5

Because it is FXXS4.... the '4' being the important bit

But I cannot flash:

BL_G935FXXU3ERL3_CL14843133_QB20951136_REV00_user_low_ship.tar.md5

because it is FXXU3.... the '3' being the important bit

This seems to reduce me down to the last firmware for both XEU and BTU neither of which enable me to make calls on '3' network like I have done for months before flashing.

Thanks for all of your kind help

It looks like my phone is bricked :((

All the best

Bob
[Samsung Galaxy S7 Edge Questions and Answers] rroyy:
Bob, can you flash latest XEU? We are going to get new security patch update in few weeks. April security patch not yet release. If you can flash latest XEU you can update your device to upcoming update via Smart Switch.
[Samsung Galaxy S7 Edge Questions and Answers] bobbaker1970:
Still bricked: cannot make calls

Thanks for help everyone.

I thought I would give you my conclusions so far in case they are helpful to anyone.

1 My phone was working perfectly for SMS, phone calls and data on the '3' network.

2 Because the battery life didn't seem good I decided to flash it

3 It turns out my phone was initially sold with 'XEU' firmware. But I didn't know that and so I flashed it with 'BTU' firmware - the latest edition.

4 As a result the phone could not make or receive calls on the '3' network. But... it can make and receive calls on the 'O2' network. However, '3' is my contract network and so I want to stay with that. Also, I think the companies are running down 2G transmissions ?? so eventually I may have problems with O2 .

FYI it seems the problem may be that the phone is not sending or receiving certain frequencies as otherwise why would it work ok on O2 but not 3??

**********Tried to resolve by:

5 New sim card

6 Factory reset

7 Clear partition

8 Flashing, again. I tried:

a latest XEU

b latest BTU

c previous XEU

d previous BTU

e previous XEU but with the modem file from EE

f previous XEU but with the modem file from 3

g previous XEU again but then did an over the air update to current XEU

Non of them worked.

*****Conclusion

My phone still will not make or receive calls on the 3 network - it won't register on the network (yes I have tried resetting, selecting network etc etc). It sometimes works with text messages though?? And 4G sometimes works. Otherwise the phone works perfectly, just not for phone calls.

Again on the O2 network all seems to work and I can make and receive calls.

So, to for me, it is bricked in that I can't use it as a phone.

I find it completely inexplicable that I can't get it to work on 3 for calls. There doesn't seem any logic to it.

But thanks everyone for all of your kind help. If anyone has any more suggestions I am willing to try them. Especially if they know how to turn on the relevant frequencies on the phone.

Bit of info: Samsung kindly ran a test to check the reception and transmission of signals. But the test wouldn't even start because it couldn't test the first frequency (apparently it should test lots).
[Samsung Galaxy S7 Edge Questions and Answers] bobbaker1970:
RRoyy

Many thanks again for your reply. You've been very kind with your time.

Yes I can flash the current XEU but it still doesn't work. And I flashed the previous XEU and then did an update using over the air from the phone. But still it doesn't work.

Very best wishes

Bob
[Samsung Galaxy S7 Edge Questions and Answers] bobbaker1970:
Weird

I put an EE sim into my phone (the previous owner had bought it unlocked but used it with an EE contract).

Then I put my '3' sim into my phone. And............ I was able to make one!! call.

After that it stopped working.

That was on XEU where I had downloaded the previous version and let it update over the air.

Does this in any way help diagnose the problem??

Thanks again.
[Samsung Galaxy S7 Edge Questions and Answers] rroyy:
Flash that version and update via smart switch please not ota. I've XEU device and I flashed btu many times to my device never had any problem. Than I update my device to TUR to get updates released bu Turkish operators.

There must be something about installization process that's why I'm asking you to update your device over pc via Smart Switch.
[Samsung Galaxy S7 Edge Questions and Answers] bobbaker1970:
Thank you again RRoyy

I shall do as you suggest.

I think you are saying:

1 Flash previous version of XEU???

2 Then update to current version of XEU using 'smart switch'

3 Should I flash with my '3' sim card in the phone. Or not?

Is that correct?

Also, a small point but I didn't know smartswitch could update firmware. I have never used it. But shall give it a try.

If you could please tell me if the above is correct before I do it I would be most grateful. And thank you again for your time.

Side note: Today I tried an EE sim. It does work, but only on 2G. Not on 3G or auto switch. So, it may be the case that the original flashing of BTU that I did first of all somehow made the phone only 2G? Is that possible?

++Update. Smartswitch spent ages trying to update but failed at the last bit. IT downloaded the software but failed on installation. I have no idea why.

Any suggestions??

Best wishes

Bob
[Samsung Galaxy S7 Edge Questions and Answers] bobbaker1970:
Hello again. So I still haven't had any luck.

I flashed the BTU before the current version. But then the smartswitch wouldn't update it to the current version. It claimed it was already current. It wouldn't update over the air either.

I then flashed the XEU before the current version and I DID manage to get smartswitch to update it to the current version. But '3' sim still not working.

It seems that the problem revolves around certain frequencies that do/don't work on my phone. I suppose it could be a hardware issue though that is unlikely seeing as it happened immediately after I flashed the phone for the first time.

This gives rise to two quesions:

1 Does flashing the firmware get rid of EVERYTHING on the phone. Or does it leave residual bits of information that aren't overwritten?

2 Perhaps the problem is the 'CP' software which seems to be the same for all the options I can flash.

3 If I could flash with firmware from another country with a different CP file perhaps that might push the phone into action.

4 Is there a way to check what frequencies my phone can and cannot receive transmit. I don't mean the specifications. I mean the actual received/transmitted frequencies/bands.

Many thanks again.

Finally, apologies for posting this without logging in but there is a problem with trying to login to the forum on this Chromebook. The space for name and password is not visible. Works ok in windows 10 but not on my chromebook.

[Samsung Galaxy S7 Edge Questions and Answers] UsmaniMustafa:
1) Yes I believe the efs of the phone is not wiped when flashing software. Everything else is wiped.

2) You could try another country rom. Just make sure the model number is the same. Changing the CP could work as CP is the modem file.
[Samsung Galaxy S7 Edge Questions and Answers] bobbaker1970:
thanks

Many thanks that is very interesting.

I just tried flashing Italian software. But still I cannot get onto 3 network. I used the Italian one because most countries seem to have the same CP file - I think?

Is it possible to clear 'efs' before I flash a new rom or will that cause problems?

Many thanks again
[Samsung Galaxy S7 Edge Questions and Answers] UsmaniMustafa:
Why don't you try a software with totally different country like KSA or PAK.

I had a similar problem with custom rom where my sim signals weren't working and I couldn't make any calls. The problem was my efs was either corrupted or deleted. So i flashed a the BTU firmware(my orignal is PAK) and it worked.

---------- Post added at 07:03 PM ---------- Previous post was at 06:32 PM ----------

Have you tried getting a duplicate sim card of your 3 sim, in case the sim it self got damaged somehow. Since other networks work fine.
[Samsung Galaxy S7 Edge Questions and Answers] bobbaker1970:
Hi and thanks to both

I did try firmware from two other countries: Australia and Italy. Neither worked.

I did get my sim replaced but it doesn't work in this phone - it works fine in other phones.

However, O2 sim seems to work okay in this phone.

It's very strange. All of this happened since I flashed firmware with current BTU - apparently my phone was XEU and I should have used that. Quite why that would stop '3' working is a mystery to me.

But thanks again everyone. If anyone knows of any possible solutions please let me know.

I am grateful to you all for your kind help.

Bob
[Samsung Galaxy S7 Edge Questions and Answers] UsmaniMustafa:
Your situation is very strange indeed. Flashing another countries firmware should not cause this. Are you getting reception(signal bars) on the 3 sim. Or it says emergency calls only?
[Samsung Galaxy S7 Edge Questions and Answers] bobbaker1970:
Thanks, but it wasn't caused by flashing another countries firmware. My phone is UK and had UK XEU on it. But I flashed it wit h UK BTU. That's what caused the problems.

Since then I have tried flashing with another countries firmware to try and restore working with '3' network but nothing works.

The only thing that works is 2g and O2.

Thanks for your help

Bob
[Samsung Galaxy S7 Edge Questions and Answers] UsmaniMustafa:
Are your modem and bootloader up to date?

One more thing when you flash via odin which file do you use home csc or csc?
[Samsung Galaxy S7 Edge Questions and Answers] bobbaker1970:
csc

the files come in a set and are the latest
[Samsung Galaxy S7 Edge Questions and Answers] bobbaker1970:
Something strange. My 4g for data is good with my '3' sim.

The only thing that doesn't work is when I call a number it doesn't go through. And people cannot call me.

This is strange.

Also, with an O2 Sim I get voice calling and receiving.

So it would seem the problem maybe with 3G??? Is that the band that '3' use for voice?

Can anyone explain this strange problem.

2G OK for voice and text

3G???

4G OK for data

It seems so strange. Could it be hardware? Or some kind of software switch that remains in place even after flashing new software. Could it be stored in the phone memory and not overwritten when I reflash the firmware?

Anyone know about these things.

Thanks again everyone.
[Samsung Galaxy S7 Edge Questions and Answers] UsmaniMustafa:
Try resetting you APN to default from settings and then changing its settings to what your network weibsite says.

and change network mode to auto connect. (If it is ready auto connect, change it to something else and then back to auto connect.)
[Samsung Galaxy S7 Edge Questions and Answers] bobbaker1970:
Thanks I just tried that but it didn't work.

What do people think about using odin to 'nand erase' and 'repartition'? would they get rid of any residual data that might be causing a problem? Or are they too dangerous to use and might I brick the phone?
[Samsung Galaxy S7 Edge Questions and Answers] UsmaniMustafa:
Nand erase and pit are things that should only be messed with if you know what you're doing. I haven't tried any of those settings personally but there are a lot of threads on XDA that suggest not to temper with those settings.

Really sorry unable to help but your problem is quite unique.

There is one thing you try is downgrading your phone to nougat or marshmallow with XEU firmware which was original. It's a wild card but completely changing the OS should wipe everything.
[Samsung Galaxy S7 Edge Questions and Answers] bobbaker1970:
Thanks I would love to downgrade the firmware but I don't think it's possible. I tried going back 3 versions of software to 8.0 from December 2018 and it wouldn't let me.

If anyone knows how to do it I would be grateful.

Thanks again

Bob
[Samsung Galaxy S7 Edge Questions and Answers] UsmaniMustafa:
That means your phone is one the latest bootloader. Downgrading won't be possible.

Try contacting Samsung, maybe they have a fix for this.

Since nothing seems to work, you could go the rooting route but it has its downsides.( Secure folder and Samsung pass don't work or any other app that uses KNOX)
[X Style (Pure) Q&A, Help & Troubleshooting] Hybrid Theory:
I couldn't find a solution to this problem myself so I was hoping someone else could provide some insight. Whenever I try to flash any Lollipop roms whether it's stock or custom my phone gets stuck on the boot logo and reboots. I tried downgrading TWRP and flashing the stock Lollipop firmware then going to a custom ROM but no avail. Nougat and Marshmallow roms work fine.
[X Style (Pure) Q&A, Help & Troubleshooting] aybarrap1:
You probably will not find a solution as no one has really developed a lollipop ROM utilizing the MM or N bootloader/ radio.

I am running Android 9 on a Galaxy Note 9. On several occasions while reading my text messages my phone will call the contact who's messaginges I was reading. This seems to happen mostly when I try to put my phone in my pocket after reading a text.

I am curious as to what could be causing this and if it can be turned off. I suspect it's some sort of gesture or accessibility feature I am accidentally activating, but it's getting quite annoying so whatever it is I want to turn it off. Any help identifying the source is appriciated.

[General Questions and Answers] mvonobb:
Help! Our "unlocked" Sprint Galaxy 7's won't do wifi calling with our new provider!

We have 2 Sprint Galaxy S7's, GSM-930P. Never set up wifi calling on sprint but had an icon for it and they were always asking me to set it up. Switched to Mint mobile which works on Tmobile's network. When on wifi at home or work can't send or receive MMS, pictures, but turn wifi off and the pictures go or download. Never had this problem before. Have wifi turned on through our provider and there is a greyed out wifi callng icon at the top of screens next to signal strength and wifi icon.

They say I have to turn it on in our phones for it to work properly but that setting isn't in any of our menus. I've found other threads talking about it being gone on sprint phones but the phone is capable of wifi calling from what I've found. I found one post somewhere about someone "flashing" their phone with the tmobile software or something and it working. On Mint mobile's site they have a list of compatible phones and our IMEI isn't listed as being compatible? It's so confusing and frustrating. I know these phones are capable of wifi calling and think that it would make our phones work better if we changed some things up. I'm trying to figure all of this out but not sure how to do it or who to listen to online. I would appreciate any help you could offer. Thank you!

There are 3 bookmarks baked into the Samsung browser that can not be removed. I can live with the one for Google, but the one for Mobile Web and Accessories are annoying the hell out of me, especially the mobile web one as it doesn't even take you to a functioning web site.

Used to be that disabling the partner bookmarks entry in the apps section took care of them, but that is no longer the case. To make it even worse, you can't even reorder them, so they are always at the top of your bookmarks.

Anyone come across a way to get rid of them?

He actually wasn't telling you which browser you HAD to use, he simply stated his opinion which he's allowed to do! If no one gave their opinions about apps we would never know which apps are better than another.. Calling someone names like you did (kid) and telling them to keep their mouth shut is lowering yourself and making you look bad! But just so you know [MENTION=3615140]HipKat[/MENTION] is one of the smarter people on here.. There's a reason his names a different color.. Lighten up some .

Also, if you want the bookmarks gone first try long pressing on them to see if they'll pop up a delete function and if it doesn't then there's only 2 options left and 1 of those you can't do because there's no root access on bootloader version 5 and the second thing you could do is get an app called package disabler pro it costs money but it's worth it to get all the bloatware out of the way or you can look into BK disabler too..

Edit: You can also download the older version of the Samsung internet app in .apk format and uninstall the current version and then install the older version.

Hello. Is it possible to get raw sensor data from Mi Band 3? It must be in real time. By sensor I mean accelerometer.
[General Accessories] sozen:
The post is very old dated but for enthusiast here my reply.

Notify for Miband/Amazfit and Master for Miband/Amazfit apps can interestingly read real time sensor data like accelerometer and PPG sensor. Besides, Notify for Miband/Amazfit app provides lots of Tasker boradcast intents. Here already shared on reddit with an Automate Flow example: https://llamalab.com/automate/community/flows/41408

Tasker like broadcast intent method is the bypass-solution with non-programmers. Further information can be read from this medium share.
