[Q] Can't turn On WIfi after new installation roms - AT&T, Rogers, Bell, Telus Samsung Galaxy S III

Hi
i had some software trouble with my SGH-i747M, any way I ended with cyanide Rom, but because the camera doesn't work i want to come back to the original roms.
So i find a stock rom 4.4.2 (from March 2015 ?), but after booting i can't turn on wifi (it not grey, it just can't stay ON, i mean i click and immediately i came back to OFF, like and auto switch or something). So, i try with a backup. samething happen. Each time a make a clean install, reset de system, Data, cache, delwick ect.
After that i try again with Cianyde lollipop (the same rom than the first time). and then the wifi is ok. So a re try it with and another backup, and the wifi can't turn on gain.
I don't know if is the rom, the firmware, the modem but.. why the cianyde lollipop rom work but not my kitkat back up ? everything elle in the rom seem ok.
I have a SGH-i747M from Bell, looking for a solution (stock) because i want to sale it in a working version.
thank you

My problem is with stock rom. After i flash with clean install stock kdz rom 20e, my so is messed up.
I already tried factory reset after clean install and didnt work. stock 4.4.2 is ok but stock 5.0 no
when you flashed kdz did you choose cse flash?
Yes i did. Many times. It is very strange. I flashed again Android now again and everything alright because i want 5.0 fully functional
But someday i Will want stock on my g3. I even tried update 4.4.2 to 5.0 by ota and i lost WiFi. Then i made a factory reset and lost nav bar, status bar again
gc device locked
i recently bought a g3 and i factory resetted it but mcafee app locked my device and i can no longer use it , i thought flashing stock firmware would solve it because hard reset was blocked by the stupid app. im not sure but i think download mode is also blocked , how do i go back to stock then?thank you guys your help will be much appreciated.
Download Mode is Blocked?

[Q] Wifi frosted out after un-brick

Ok bricked my Metro GS4 the first time I tried to root, did the un-root and it worked fine, except the wifi will not turn on, I installed TM 4.4.2.
I rooted it with towelroot so it is rooted, I have read that a factory reset worked for some people where their wifi was frosted out, but my question is,
1. Do I need to worry about that since I am wanting to install custom roms, is the wifi just a problem in the rom I used to flash it to, or something else that will be wrong in any rom I use?
2. If I do the factory reset, does this remove root access?

1. You should make sure everything works before flashing any ROMs. You should consider using Odin to return to complete stock, then check wifi before moving forward. Then never flash any stock based ROMs with later version OS than your modem and bootloader or you will again have wifi problems.
2. Factory Data reset does not remove root. It does remove all other user data and downloaded apps as well as things stored on internal storage so back everything up to a computer first.
You stated
"Then never flash any stock based ROMs with later version OS than your modem and bootloader or you will again have wifi problems."
I not sure if I understand, "stock based" I think I used a stock, out of the box, backup, for my un-bricking, that is a 4.4.2
How do I know if they are a later versions OS of my modem and bootloader? I see one here on XDA that is "Stock/Base" that is 4.4.4, but don't know if it is later OS or not.
Factory reset did not fix wifi, and I had backed up with Titanium, but once it restarted titanium cannot find the backup on SD card, so I guess I don't know how to do that either.
Got it going, flashed it to 4.4.4 NH7, and Titanium worked great, I did the backup and then copied them to the SD card, not sure why I can't save them straight to the SD card, but this way worked.
Got your wifi back?
Pp.
Yes got the wifi going

Service issues after upgrading to 5.0

I upgraded from a stock rooted 4.4.2 to the OTA 5.0 using the ROM that was rooted. Some apps for my smart watch don't work in 5.0 yet, so I went TWRP and restored my backup. After booting, the phone will not get any service at all. It shows it's searching for service then gives a red "x" then starts searching again. This is process that just keeps going. I flashed the stock .tot file using the LG flash tool to get the phone completely back to stock. After doing so, the radio still won't get service. I then applied the OTA push of 5.0. After 5.0 was installed, the radio gets service without any issues. I used the LG flash tool again to go back to 4.4.2 stock and same issue; no service. Updated again to 5.0, and I get service. Any ideas on what's happening here? Is it the firmware for the radio that's having issues?
I was able to fix this by playing with the APN settings and it was able to get service, but no data. I then went back to the default t-mobile APN setting and now it works.
Same Issue
After using lg update tool to go to new 5.0 update, I put twrp back on and flashed cm12 and bliss pop rom on mine and service 100% drops out and only came back after a battery pull or a reboot, e tried to re-install roms on both and after having the same issue with the roms i tried a custom kernel issue went away and then came back, so i haven't tried AOSP since the t mobile said they'd send me another brand new phone ....but once i put everything back to OEM using the lg tool it's been 100% working again with no issues... i will try AOSP when the new phone gets here,, im thinking its kernel related
You need the new modem, boot loader, and boot images. You can't simply just flash a ROM unless all 4 (system included) is packaged as so

Upgrade broke the GPS

Hi all, I have a note 2 shg-i317 that was originally on Bell in Canada. It was unlocked and the aws mod done to it, I use freedom mobile, aka T-mobile in the states.
I was running a Rom for the past 3 years Slimfast 4.4 and liked it. I had tried Nugat on another phone, thought I would try the [ROM][7.1.2][OFFICIAL] LineageOS for N7105
I did the upgrade, broke the root, could not get a few things working, so I decided to restore the Slimfast backup I had just made (complete including modem etc) and everything works except the GPS.
GPS for me is huge, I use it a lot. I cannot lock on to 1 satellite now. Before i was able to lock onto a minimum of 16 in about 30-45 seconds, if outside.
I really dont care if I can get to 7.1 at the moment. I need my GPS back - any troublshooting for getting GPS to work on this phone?
James
I would try to flash the original stock for your phone and country from sammobile. com
Gps should work normaly then. If not your hardware is broken. If it works you can always flash your data back from your Slimfast rom.

Crap, I am posting here, because I did it again. Again not sure how. I tried to run Reserection, and I guess that messed up the GPS.
To put the original stock rom on.. I have to do that through ODIN? I dont remember how I fixed this last year.. Sorry.
Hope somone can help I need the GPS.
James
ps. Used odin 3.09 to flash the original rom... still no GPS
You flashed the latest 4.4.2 room?

The Rom that I flashed to try and restore the GPS was I317MVLUDNF1_I317MOYADNF1_BMC (mine was an originally BELL phone)
But that did not repair the GPS from me flashing resurection.. I THINK did it. I flashed an android 6 and an android 7 rom. (Mokee) but tried to go back to my Slimfast.. and the GPS was now broken.
Basically what I did a year ago.. somehow I fixed it then.. but cannot remember at all how I did it.
James
The note 2 sold by Rogers, Bell, and Telus are exactly the same model and stock roms from these carriers can be cross flashed.
Try flashing the stock ROM twice in Odin with a factory reset in between each flash.

Do you mean boot up the rom.. run the reset in the rom? or flash.. - load TWRP back in.. WIPE.. then FLASH again with odin?
Thanks for helping btw.
James
I have backups (complete all partitions) of my rom.. Slimfast 4.4 from 2-3 days ago.. when I tried this. SO.. if I can get the Factory rom to restore the GPS.. how can I restore the backup.. I saw somewhere that the EFS partition could be left out and that might help? dont restore the modem? how??
James
I meant flash with Odin, boot into stock recovery, factory reset, flash again with Odin, boot into stock recovery, factory reset, and boot into the stock ROM.
Nope, still no GPS lock.. I have the flashing circle (always had) and it will not lock.. I read about where people go into a service mode and rebuild the NV? .. I assume this is something that Mokee or Reserection did.. not sure how.
Any other ideas?
James
what about using Odin or TWRP to put different modems in? does the modem effect the GPS?
tried this.. does not seem to. grrrrr wish I knew how I fixed this.
James
I assume there are no loose wires. Does it get a lock when using wifi? Not sure what else to suggest.
Not sure about rebuilding NV.
No.. I broke it with playing with custom roms.. Liniage was last year.. I did not try that this year.. but tried both android 6 reserection and android 7 Mokee.. and I am pretty sure they messed it up.. I am also pretty sure there was something I did .. easy like load an old STOCK rom and it fixed it.. I was then able to put my slimfast 4.4 back over it and it was fine. Unfortunatly .. not enough people still using this device.. I will have to have patience I guess.
James
So I have tried differenct stock roms, but I think the issue is ODIN will not restore code from a rom image that is HARDWARE based. I wanted to use Samsung smartswitch but they disabled the part of it that allowed you to factory reset the phone, this seemed to work for several people. Many have also reported entering a code and going into a service mode.. there you can do to a menu that will rebuild hardware modules back to default. But I have not been able to get into that mode because it seems to be a touchwiz only option, and I cannot find a factory rom that is touchwiz based for this model.
What needs to be done is a true FACTORY ROM image.. that would revert all software and hardware back to original, but I cannot seem to find that anywhere.
James
The only factory roms that I know of come from places like sammobile.com and they are all based on TouchWiz which is Samsung's launcher.
So guess what? put Ressurection back on.. and the GPS is back.
I cannot get it to work in any KitKat based rom.. but now anything Marshmellow up.. works.. HMMMMMM

Converting back to stock firmware from Custom Os [HELP]

I'm currently on DotOS 5.1.2 currently and want to go back to stock samsung firmware. I have a sm g9600 from mexico i believe. If i try to flash whatever the newest firmware is for mexico would that work? Is there anything special i need to do to prep for the new firmware? DotOS is on android 11 and the highest android version i have found is 10 from samsung. I'm wanting to revert back so i can have bluetooth calling and screen mirroring working properly again, and hopefully less battery drain.
It should be working fine, just flash the newest rom via Odin. After flashing you might get some errors during the first run. In such case you need to go to standard recovery and do a factory reset + wipe cache.
I am also unhappy with the amount of time I have wasted with custom ROMs for this phone. How do I go back?
