[Q] Wifi frosted out after un-brick - T-Mobile Samsung Galaxy S 4

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

[Q] flashed stock 4.3 (rooted) with ODIN, can only connect to EDGE data.

Hi everyone, this is somewhat complicated and il try my best to describe what happened.
My device is a i747m (rogers).
I was running CM10.1 (running gapps-jb-20130812 and CWM recovery 6.0.4.3) for a long time, tried to update to 10.2.
(i messed up on 2 things.I don't think i cleared neither of the cache or data and also didn't have proper gapps which would be 20130813).
After installing 10.2 through recovery, it would just stay in the boot Cynogen booting logo.
i restarted into recovery, since my old CM10.1 zip was still there, i installed that instead, but same thing happened, it would just stay at booting logo.
I had made a nandroid back up from before all of this, and so i wiped data, dalvik cache, cache, formatted system, and i recovered into that, which was a stock 4.1.2 rooted (rogers).
However, nothing worked, only WiFi. I couldn't make any phone calls, send/receive messages, or get data.
I then used ODIN 3.07 to flash the new stock 4.3 rooted (rogers). WiFi worked as before, but i still couldn't make any phone calls, send/receive messages, or get data.
i then re-installed the latest recover 6.0.4.5, and installed paranoid android 4.4.2 and gapps for this version. But still nothing, so i went back to the stock 4.3 rooted.
4 months ago, when i made the nandroid back up, i also made an IMEI back up as well (i did not do a full imei/NV/EFS/IMSI/data backup) , i only had my IMEI backup, so i wrote using "NV items reader writer" the IMEI back onto my phone, and now i can recieve/send messages, and get phone calls and make phone calls. wifi also works.
But my data is stuck in Edge, its extremely slow, takes 10min to download a 15mb file.
so far:
-The APN settings are correct
-my IMEI number in settings menu, matches the one on the back of my phone.
-network mode is GSM/HSPA/LTE
-i have installed the latest modem for i747m through CWM recovery and also tried slightly older versions.
i am pretty much lost and i dont know what i should do.
-rogers has told me to use kies and perform backup and then recovery, apparently that will factory reset my phone.
-should i simply use kies to install the latest 4.3?
-does anyone have the imei/NV/EFS/IMSI/data files? or the full NV file?
-should i install CWM recovery and wipe everything that i can? and re-install stock rooted 4.3?
-should i use QPST to fix my IMEI? <-- dont know anything about this, noticed a few threads.
i have used these threads in all my rooting and so forth.

[Q] [Help] I was on the Davandh Rom Kit Kat 4.4

I have a UVUEMK2. I had to get the phone encrypted for work, little did I know it would cause issues. I would have to go back to stock for the work email to work. Wouldn't sit well with root.
I backed up everything and tried to remove encryption before doing ODIN to no avail. No one really knew how to remove encryption. I tried factory data resets, and finally I tried to ODIN my stock firmware but now that's stuck on the T-Mobile 4G LTE Boot Screen.
I went into recovery and tried to factory data reset from there, but somethings fail because of the encryption. I did it anyways, wiped data at least. Reboot > Still Stuck, but no encryption screen this time?
Now I flashed the same stock firmware again, if anyone knows what to do or how to remove encryption that would be awesome. Right now I can only access recovery and download mode.
I don't need anything from the phone, everything is backed up.
It was rooted, on Davandh 4.4.4 Kit Kat. Encryption from the security settings. Baseband UVUEMK2.

[Q] screen on lag after downgrade from 5.0.2 to 4.4.4

Can anyone help with this. I have a sprint note 4 that I rooted and was working great, but wanted the stock 5.0.2 upgrade. Used odin to install stock 4.4.4 and remove root. Worked fine phone took the 5.0.2 upgrade. Rerooted and installed wifi tether router but could not get it to work, found it is not working on 5.0.2, dam. Used odin once again to return to stock 4.4.4, rooted, installed wifi tether, everything works with one problem. When turning the screen on I now have a severe lag between the button push and the screen light up.
I odined back for other issues and still had problems. .even a backup was not working... i wiped everything, all data etc, 2 times then went back to nie....then took the otas back to lollipop. .now everything works fine except i still hate the colors

Fixed, it was a bad sd card had nothing to do with the dowgrade.
Good to hear you found your problem. However if it's tethering that's keeping you away from Lollipop then you can put that to rest because you can easily enable wifi/usb tethering without the need for a third part app like tether router (which i have payed for as well). If you expect to stay on the factory rom/firmware then Lollipop would be a wise choice due to the new ART (android runtime) and it's overall effeciency compared to KK . It has a lot of benefits and other than the stock colors, there's no reason you shouldn't update to Lollipop. Do a little searching here in the Sprint Note 4 forum and you'll find a few easy ways to enable the built-in tethering.
Thanks for the info, did exactly that, found galaxy tools would provide the tether

You are SOL for now. Cant downgrade rom OE1, but a new OTA is about to come out, I'd sit tight until then. or...Many people flash Noterized Rom. Try flashing that and continue your troubleshooting.

OH1 recovery image -or- help getting back to stock firmware

Hi folks. Admitted Noob here asking for help.
[backstory]
After many years resistance I finally decided to get a phone. Freedompop's free plan was enough to push me over the fence. Found a nice S3 (L710VPUDOH1) on ebay and bought it. Everything was fine...except the stock rom had so much crap in it I was about to have a seizure. Back in the day I had put CM on a nookcolor so I thought that was the way to go. I consulted with a friend who assured me that CM played nicely with freedompop so down the rabbit hole I went.
[the first sign of trouble]
Installing CM went fine. Odin. Heimdall. I installed the latest clockwork mod touch recovery (6.0.4.5). Then I installed the latest CM snapshot (cm-12.1-20151117-SNAPSHOT-YOG7DAO1K7-d2spr.zip) and the appropriate gapps. Worked great. Nice and fast, good configuration options, no bloat....but it couldn't connect up to the 3g/4g network. Freedompop worked as long as WiFi was on and would not otherwise. Crap. What's the point of a cell phone if I have to have a WiFi hotspot???
Some googling revealed that the APNs were wrong so I tried that route. I was able to get LTE working but never got 3G. I live out in the boonies, so 3G is kinda important. Also found that CM breaks Sprint's PRL auto update which doesn't seem too happy.
[^H^H^H^H^H]
So, I decided to go back to the factory ROM and see how FP worked as I dutifully made a backup before installing CM. Now the SHTF. When I restore from backup in CWM (followed by a factory wipe data and cache to avoid the boot loop) the ROM cannot connect to Sprint's network. Doesn't know its IEMI or much of anything. It does connect up to wifi, log into my google account, get my paid apps, etc....but still no phone.
I installed Kies and attempted to restore/upgrade firmware (non-emergency mode). Kies got to about 66% and said there was an unexpected error. I'm guessing it didn't like the custom recovery and just plain quit on me. Was worried that I'd made a brick but alas I could still get to download mode. </bullet dodged>
I would like to put the phone back to stock (including recovery) but I have no factory recovery image. Does anyone have a recovery image for L710VPUDOH1? Alternatively, is there any harm in flashing the full ND8 onto the phone even though it had OH1 running before? I seem to remember reading things about bricking phones when trying to downgrade....which is in effect what I would be doing.
Any other suggestions about how to get back to stock would be most appreciated.
TIA
You can flash nd8. Nj2 is newer though. I don't think anyone has captured the oh1 tar yet. The only thing you should not do is flash anything before nd8 (pre Knox) like mk3 or older. Which is jellybean anyways so....
Hope this helps.
Yes, thank you; that was exactly what I needed to know.
I have a working phone at the moment so stock is not necessary required. For others that may be interested I flashed in Wicked X 8.2. From there the phone once again knew its IMEI and I was able to carrier reset and get it activated with Freedom Pop.

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
