Fix Wifi and Hotspot Won't Turn On Problem.... - Galaxy E5, E7 Q&A, Help & Troubleshooting

Recently I flash custom rom cm 13 (unofficial) for sm-e500h, after flashing this custom rom I face some problems like audio speaker sound is very low, radio stop working, etc.
After a week my touch stop working and device getting stuck in boot
So I flash official ROM but the WiFi and Hotspot stop working
Formating device even not fix this error
Solution : Flash the same official ROM again using odin to fix this issue. It works for me so I share this to help others facing same problem.

[Q] What is params.bin and can it mess up my phone or can it fix my bluetooth?

Hey guys,
I'm currently using OzcanRom and it's just great - strongly recommended!
My only issue is exactly the same issue as described in this post:
I'm facing a very strange problem as i'm unable to switch on my bluetooth... last week only i rooted my phone and installed CWM recovery...then i installed Custom Rom's like Hassan ROM, Omega ROM, Cyanogenmod 11 Rom, Pacman ROM etc etc just to check various Rom's and their features out.....At first i installed only one ROM at a time and den also dual booted two ROM's by romswitcher...While i was checking my phone once i discovered that my phone's Bluetooth is not turning ON...The toggle is only becoming light green and also from the settings its only showing turning Bluetooth On but it's unable to turn bluetooth On.....Now i googled my problem and read across various forums for solution...I tried various things also flashed my firmware to stock samsung but still bluetooth does not turn On...also i flashed with stock samsung firmware of feb and march 2014 and updated my phone over OTA but still the problem persists....i even installed latest perseus kernel while rooted but still could not turn my bluetooth ON.
I would be very grateful if someone can help me solve my problem and help me Switch ON my bluetooth as it is very needed aspect for my daily use.
My Version of S4 is i9500 with android kitkat 4.4.2. Also all my other features are working normally on custom ROM's too.

I too installed this Omega rom at some point and once I did that these problems started.
A user in that thread posted a reply in which he uploaded a file which he claims fixed his problem.
I really need my bluetooth to work again and would love to flash this file using Odin if it would fix the problem
BUT
I have no clue what implications flashing this file can have, can it mess other things up? I've spent the last four hours setting things up again in my new ROM and I would hate to have to do it again or even worse, cause some unsolvable problem with my phone.
I assume some of the developers here could help me out - should I run it?
Thanks!

Wifi dropping on Miui 7.5.0.3 Android 5.1.1

Hello guys.
I have one Redmi 2 Prime Global with Miui 7.5.0.3 Android 5.1.1 and after it changed, thru OTA, to Lolipop the wifi got crazy.
It's connected in wifi but it, randomly, stop traffinc data. A simple put in airplane mode, fix it, but after a couple of minutes I lose the wifi again.
For the sake of the discussion, I already have searched all the internet and the mess that is the Miui forums. Some other users have the same issues but there's no information about solution.
It seems that it's a driver issue with lolipop and even the Miui 8 beta has this problems. I know because I have tried it.
I trully appreciate if anyone can help me on this issue or knows any more info about it. Thank you.

Welp. flashing Jerrica makes things better, but does not solve it.
Now my phone has a more stable wifi, but its has the same issues still and randomly reboots (something like one time in a couple of days).
Any more suggestions are welcome, as it seems that you have experienced similar issue.
This might not be the Problem but I think it is ....
Flashing MIUI Update 7.5.3 caused many a Problem ,
Like , the Navigation bar Stops working .. Volume keys Stop working , phone Reboots itself and heats like hell ...
I tried Every Method to solve it , even with a Format , didn't work ,,.. then I just reflashed the ROM and it was Gone .. if you don't want to Do a Format (dalvik/cache/data wipe) then Dirty flash it again .. but I'll say , do a proper flash , backup all your apps and data using titanium backup , upload your things to google and do a Proper flash ..
Hope it solves it , I have Experienced the problem and This Solved it in many cases apart from This too . MIUI 7.5.3 supports both 5GHz and 2.5GHz so it shouldn't be a Problem with Wifi ..

I think you should flash a fastboot rom of 7.5.3, i am out of suggestions:laugh::laugh::laugh:
Quick update, for the sake of who has the same problem.
Nothing fixed it (in any lolipop version). But last week Xiaomi published the Miui 8.6.9.29 beta, after a few weeks with a pending update for the Redmi 2 prime. With this update the wifi, finally, is fixed.
Thank you guys for the help.
