Samsung A5 - SM-A510F: WiFi & Bluetooth Malfunction Post Android 7 Nougat Upgrade

As in the subject, I had an Android 6 phone and everything worked fine. After upgrading to 7nougat, I lost the ability to turn on WiFi. Not that it does not see any networks, it just tries to turn on "on" and so much on the topic - the slider returns to the OFF position.

In addition, I noticed that Bluetooth also does not work, for me it is less important, but maybe it has to do with WiFi. With Bluetooth, it sometimes turns on and displays devices, but I can not send anything.

I've already tried the factory reset, but with the wipe I noticed something disturbing:



I also tried recovery from a smart switch, but I have to enter the recovery code I do not know. The phone is from Germany and it turns out that someone was already doing something there.

I also tried to upload the Polish Xeo Softs from Odin, German DBT downloaded from SamFirm, some progression when I uploaded DBT with Android 6 marshall, because with wipe there was no error.

Anyway, there is no WiFi, no switching, and my hands are already falling

Enter the factory settings ... start from the beginning because maybe he did not like something ... - best regards

The factory settings do not give any result. ADres Mac is displayed, Wifi Version is 0 and it does not work.

I do not know if I understand correctly, but when I try to install software with smart switch I get a message that I will install PDA, CSC, PHONE version with CKQ3 terminals.

After installation, the version number changes to just that, but the modem version remains unchanged:



From what I read the versions should be identical? It's a damage to the module, it's just weird that after updating the android from 6 to 7.

I could use a soft repair multi-file, I found 5.1 if you are not scared then try to upload it. https://www.androidfilehost.com/?fid=24459283995296401

There is no valid download file in this link, only a mirror with a transfer for 2 days of downloading - is there any alternative?

Well, unfortunately, I do not have anything else and from this source I often download and usually 3-4h is made.

Check it out: http://www.emmc-files.com/index.php?a=browse&b=file-info&id=774

Okay, we'll wait. The downloaded file should contain 4 files, successively to be loaded with the Odin program (BL + AP + CP + CSC) plus unpacked from the CSC PiT with the AutoReboot + RePartition + F.Reset.Time options selected. Is everything correct?

PiT does not have to be and repartition do not tick too.

In the end I sucked in, I started, but from what I see it or the program has hung up, or waiting for PiT?

I have a small problem here, because the file I downloaded from your link did not want to take off at all.
So I decided to put on the phone system 6.0.1 where the wipe was not an error E: misc partition like from the photo from the first post:



Here in this system, the modem version has also changed, theoretically correct because the same as the software version:



The attempt to upload your "recovery" has failed, probably at boot.bin:



Yesterday I returned to the old "working systems" several times and with each trial I was blurted by the "System Rev. Check Fail" error with the differences between DEVICE and BINARY numbers, DEVICE: 1, BINARY: 0 - and I had DEVICE: 3, BINARY: 4.

I am currently loading the phone again, because it lay all night on the "Recovery SMartSwitch" display - after charging I will make further installation attempts.

If you have any suggestions, please write to me if this file from the link is definitely in my A5 version. When searching for a firmware on a sammobile, 3 versions are available for selection:



My model is A5 (6) SM-A510F or the middle option of choice.

The version is two A510F and A510FD so your A510F is correct, but as I wrote at the very beginning these are 5.1 repair files and I do not know if the undervaluation from 7.0 will fix the problem or not worsen the case. I think the problem would be solved by the soft 4 file system with 6 or 7 only somewhere to find it.
Maybe you have a guarantee on this phone it is worth to use because the damage you write about after the system upgrade is strange.

I know, I would use it, but it is not possible. Overseas phone, gift, no bill etc. etc.

Write to me how it is with this version of modem = fw, because somewhere I read that the modem version should not be changed to work properly. Here, what changes once, sometimes identical to FW and sometimes not.

Here you are looking for an error when downloading and installing the software - a phone with German, so has a different region designation, update downloaded from the Polish language, Polish region, SmartSwitch PL, so maybe the program installed an inappropriate FW and hence the problem with WIFI?

When displaying "Advenced Devices" at WIFI Version is 0 "zero" - so it does not detect or read information about the module.

You have saved or know what version was original, if so download the highest available on sammobile and upload.

Here, it is not certain that the telephone bought in Germany outside of the mobile phone operators' salons, should also be DBT? Only that in every FW from the DBT region there is an error "E: failed to find misc partition", where there is no such error with XEO 6.0.1 and ITV 6.0.1. And to make it more fun with the XEO 7.0 the error "E: failed ..." appears in the same way as in the DBT versions.

You can combine and even need, because there are no alternative solutions ... but I will also ask about this smartswitch recovery code. Since the program asks you to enter the recovery code from the first computer, does it mean that such code was once generated? What if I do not have it, I lost it or I forgot, or the "first computer" broke down, or anything else that could have contributed to the loss of this code - in this situation the user / owner of the phone is not able to use this mode in any way?

I did not have certainty and I do not have one, but I found an old backup made with smartphones, there are data to be read out there somewhere?

Added after 4 [hours] 10 [minutes]:

I confirmed the DBT region - designation from the page: SM-A510FZDADBT

Currently I am restoring this backup, in the meantime I am downloading the latest version with sammo ... because from 2 days it is newer. I'll let you know what will come out.

BTW. I talked to a Samsung consultant and told me that my model did not provide for the possibility of changing the region, and possible, and even more "recommended region change" (because it will avoid similar problems in the future) is only available at authorized Samsung services (for a fee) .
Overall, a great idea ... I can already see it as a Polish diaspora from abroad arrives on holidays, someone will probably fall for such equipment as a gift and immediately service

I had the same problem in this model after installing the wrong softa. The phone was Russian and the soft was uploaded to the European version. After a few attempts, we managed to upload the right one and everything returned to normal.

The strangest thing was that everything worked as it should, only you could not turn on WiFi. The slider settings could not be moved. As for bluetooth, I do not know if it worked because after the discovery of a non-working wifi I immediately took on the installation of another softa

Well, I think so, at the moment something has gone down because I can not change back DBT region, both DBT single file download and download the latest version from samFirm with the DBT region marked - both installations do not change the ITV region

Currently I need a DBT rom to be installed by TWRP.

Added after 10 [hours] 22 [minutes]:

Actually, everything is OK:
- return to DBT
- currently Version: A510FXXS4CQK3 / A510FOXA4CQK3 / A510FXXU4CQH2 / A510FXXS4CQK3
ie the latest software with the SmartSwitch update

EFFECT? there is still no WIFI

I dug the last parameters with WIFI working:
- A510FXXS3BPI8 / A510FOXA3BPI1 / A510FXXS3BPI1 / A510FXXS3BPI8

Unfortunately, the binary update does not allow you to return to this version.

I am continuing this subject with the conviction that the fault lies on the side of the software, the hands are already falling out of the lack of ideas for new solutions.

Maybe some suggestions?

last correct update:
PDAs: A510FXXS3BPI8
Phone: A510FXXS3BPI1
CSC: A510FOXA3BPI1
SM-A510FZDADBT
Version: A510FXXS3BPI8 / A510FOXA3BPI1 / A510FXXS3BPI1 / A510FXXS3BPI8
Board: EXYNOS5
Modem: SHANNON310

maybe I missed something ... maybe even the obvious fact of module damage?

Have you tried to download the soft 4 file by SamFirm? The latest version is probably from December 12th. Someone, something obviously mixed up on the phone, because you have a Knox flag on it. In such a system, I would recommend you, a custom rom Revolution Os, with XDA. I've been using a few months myself, and it's really ok. And if it solves the network problem, it will turn out.

I've tried, will this custom after the installation give the answer? If the wifi still will be unavailable then it will confirm the damage to the module?

Here you have this version of the software:
https://dl.samsung-firmware.org/f2a8bab3d1771...9c48afaf/XEO-A510FXXS3BPI8-20161008162810.zip
maybe not a speed demon ... but it is
Probably not help, but try. Probably the module is released.

I can not install this because it is binary secure: /
