help fixing wifi issues

Hi all,

EDIT: I just thought it might be helpful to add that everything is stock/unrooted.

I recently took the OTA update to 4.3, followed by another update about a week later (I forget what this update was called). Since the OTA, I've been having a lot of issues with wifi, as well as some instability. It seems that sometimes I can have luck activating wifi if I simultaneously activate BT. I have disabled wifi power save, and the "Auto network switch" feature. Once a wifi connection is established, it seems to stop working after a while. I have also tried to manually re-apply the update using w8setter's file a few times, with no improvement. It will still ping successfully both from the *#0011# menu as well as from a terminal emulator, but it won't actually load a webpage or data for a game.

I'd like to find a way to fix this issue, preferably without tripping Knox or otherwise observably voiding my warranty. I think my next step will be to apply the update listed on page 17 of this thread. It is 538 MB vs w8setter's update.zip which was about 30 MB iirc. Should I try a factory reset? If so is there a way to manually update to 4.2.2? Will a factory reset overwrite the bootloader?

Software details: Software version: L720VPUEMK2, Hardware version: L720.08, Baseband version: L720VPUEMK2, Build number: JSS15J.L720VPUEMK2

Sorry if this post is too long or newbish, but I hadn't bothered to learn much about my phone's software until I had problems.
[Sprint Samsung Galaxy S 4 General] cruise350:
Updates won't fix you since you already have been updated. What I would recommend is a full tar install through odin. You are on MK2 already, and something must not have updated properly. Your best bet is to download the full MK2 tar file and install it through odin. This will overwrite your current system, modem, kernel, firmware, and recovery. This will return you to full stock with all the updates in one complete install. This should fix your problem. This may or may not overwrite your data partition so make sure your important stuff is backed up just in case. You can find the full MK2 tar file here: http://www.sammobile.com/firmwares/ or you may be able to find it on this forum.
[Sprint Samsung Galaxy S 4 General] crawrj:
Yeah you need stock kernel and recovery. You also need all of the stock apps and framework. It won't pass the patch check if not. Just do a backup and then Odin complete stock on. Take the update and restore data. Or just wait for someone to post the rooted zips.

You know I think that's right in the last update. I was on stock rooted. Just changed the kernel to get out to work. Thanks

[Sprint Samsung Galaxy S 4 General] mjs2011:
That trick must only work to just prompt the update only if it's been pushed to your area.
[Sprint Samsung Galaxy S 4 General] GramKrackr:
Let's get a hold of this we need a ROM!
[Sprint Samsung Galaxy S 4 General] tasked28m:
Cleared data in framework and there you go
[Sprint Samsung Galaxy S 4 General] mjs2011:
Did you have to do anything else to prompt the update? Or did it come automatically?

Where are you located?

Im in Mn.
[Sprint Samsung Galaxy S 4 General] pistolcity:
here

Richmond, VA and i've gotten the update via clearing the google framework services. i would screen shot but it's updating :p
[Sprint Samsung Galaxy S 4 General] likearaptor:
I'm not sure about that. On a previous release I got the update by doing that trick 2-3 times, but I had some custom stuff in the /system partition so it wouldn't flash. After using Odin to set my self to 100% stock, I couldn't get the update to work, it kept saying I had the latest version. It actually took 1-2 hours with me clearing the data many many times. So sometimes it is instant and other times even after your phone tried to install the update the next time takes a little bit for it to come through again. I think there might just be slots opening every hour/minute and it just depends on how lucky you are at clearing that app right when a slot becomes available in your area.
[Sprint Samsung Galaxy S 4 General] tasked28m:
I live in Cyprus where is in mediteranean far away from US. You have to clear google framework date 3-4 times and it works. At least thats how it worked for me.
[Sprint Samsung Galaxy S 4 General] skyyrocket:
You guys updated ?? It It hasn't hit Florida and you know the update has a knox boot loader.... to double check when you update for those who did already go to download mode and see if it says knox 0x0 let me know please thanks
[Sprint Samsung Galaxy S 4 General] ChristianPreachr:
Are you guys clearing cache, or clearing data? IIRC, clearing cache wipes residual data, clearing data however wipes EVERYTHING you've done in the app.
[Sprint Samsung Galaxy S 4 General] pistolcity:
YES!

you are correct, it has knox warranty void = 0x0 and Knox kernel = 0x0

so maybe some should hold off on the update.
[Sprint Samsung Galaxy S 4 General] galaxys3man30:

where is the update.zip file located so i can upload it for you people?

i downloaded update but it wont update since i dont have enough battery.
[Sprint Samsung Galaxy S 4 General] crawrj:
Use a root explorer. Browse to the root directory. Look in the cache folder.
[Sprint Samsung Galaxy S 4 General] galaxys3man30:
Theres Mr.crawrj might have our work cut out for us in this update buddy
[Sprint Samsung Galaxy S 4 General] crawrj:
Yeah I know. Hopefully it won't be that bad though. I don't care about the knox counter as long as it will root and isn't locked. Which I doubt it would be since the note 3 wasn't.
[Sprint Samsung Galaxy S 4 General] galaxys3man30:
Yea I agree I dont think it will ever be locked but the only other main thing is with the knox bootloader it will have a qfuse so if we blow that with rooting it there's goes our warrenty on the phone

First time udpater

Hey guys quick questions. Im a new android user (coming from iphone) and Iam rooted with a few side-loaded programs, etc. My understanding the best way to upgrade as a rooted user is wait till a root is discovered/released for the version and then update; after you restore root. Two questions, one what happens to your applications you have side loaded or root only applications? Last is their a better way to upgrade then what I mentioned and/or a way to save root when you upgrade. Thanks

[Sprint Samsung Galaxy S 4 General] crawrj:
Pull the update.zip before you perform the update or it will be gone.
[Sprint Samsung Galaxy S 4 General] reTARDIS:
You can of course update to 4.3 but won't keep your current root. Any apps that require root will still be installed, they just won't work or fully work since they will not have the access they need. Sideloaded apps are still just apps on your phone. They'll remain on your phone unless you flash a new rom or format your phone. You won't ever really be "saving root", more you'd be holding out until a way (if possible) to root with 4.3 is discovered then you'd do whatever that method is. It might be that it won't require you to lose all your data but chances are to get from where you are today to 4.3 rooted in the future you be flashing a rom or doing something that'll require you to reload your apps with some 3rd party solution, manually, whatever.

Hope that helps.
[Sprint Samsung Galaxy S 4 General] kevinsturf:
How do I do it on a Mac? I'm not going to do the update.
[Sprint Samsung Galaxy S 4 General] Warboy:
umm, Shouldn't MTP mode would fine on a Mac? Just explore your phone for the update.zip
[Sprint Samsung Galaxy S 4 General] Mallen2008:
Thanks for the response. After I posted I did some googling and found a few more answers. Also to note I have a custom recovery so sounds like I cant even update OTA and will have to wait to flash the update.
[Sprint Samsung Galaxy S 4 General] crawrj:
First you have to copy it from the cache directory to your sdcard or internal storage. Then mount the phone to the computer and pull it.
[Sprint Samsung Galaxy S 4 General] kevinsturf:

[Sprint Samsung Galaxy S 4 General] reTARDIS:
I use Macs and Windows. Macs can't mount the phone like a drive like Windows can. Just copy it to your external micro SD, unmount, remove, then mount with a adapter on your Mac to pull the file locally.

[Sprint Samsung Galaxy S 4 General] mmark27:
THESE ARE NEVER RELEASED BY GEOGRAPHICAL LOCATIONS!

They are only released by google's OTA servers and device IDs at random. I imagine a future where we never see "I'm in ______ and I haven't got it yet?!" But that will most likely never, ever, ever happen.

so im assumig that all you guys are waiting on the TW version of the release right? im running slim and we are already at 4.3.1......or is everyone here just excited about the added coding for the gear functionality and of couse the new modem?
[Sprint Samsung Galaxy S 4 General] mjs2011:
I'm at work and still haven't received it. They must be sending it to people that aren't at work first.
[Sprint Samsung Galaxy S 4 General] clshores:
I think it is going to the ones that don't check every 5 minutes. :)

I am more interested in the modem than the ROM. I know it will be a while before root is established and I am pretty happy with an AOSP varient until there is root and it proves to be worth going back to the dark side.
[Sprint Samsung Galaxy S 4 General] SooooneR:
Tried all of the Google versions and I hate the layout and the way they work. I like the stock functionality and the look with a few mods added to make it better. When we get 4.3 with Wanam Xposed I will be happy... happy... happy! :) Come on Update. Will we get the update being rooted or do we need to flash back to stock?

[Sprint Samsung Galaxy S 4 General] garwynn:
Well, unless the missus asks for it I'm holding off on updating hers.

Why? Well, to be honest, she likes the phone as-is and always thinks I'm up to no good when I try to do anything on it.

Besides, if I ever get it back I would prefer to use it again for testing. The current version it's on - I think MF9 - is fine for that.

[Sprint Samsung Galaxy S 4 General] garwynn:
For those flashing, please post updates post-flash.

I think 2 big questions are on the horizon:

1) Root method. I suspect we'll need a "Root de la Vega" version versus CF Auto Root based on N3... but would be happy to be wrong.

2) Recovery/ROM flashing post-update.

I'll be honest though, #2 is at your own risk. If we had a full TAR to restore to you'd probably be okay.

Just make sure you're okay with the risk.

[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] cropythy:
I have had my SGS4 since June running CM with no issues connecting to LTE, but I recently tried PA android and could only connect to H+ as the fastest network connection and Network Mode defaulted to WCDMA preferred and could get no network connection at all if I changed from that. I tried going back to CM and still had the same issue. Reflashed stock using Odin and have since tried Shostock and CM again, but still cannot connect to LTE. I also tried my sim in my Nokia Lumia and get LTE on that so there doesn't seem to be an issue with my plan or sim card.

Does anyone have any ideas on how to fix this?
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] Te3k:
Sorry if this is a silly question, but in the interests of ruling out all possibilities: Are you sure that it's the actual connection, and not just the icons? Maybe you're used to seeing a 4G/LTE icon that isn't used in another ROM.

It wouldn't really make sense if you went back to CM and that issue persists, unless an icon setting is preventing you from seeing the icon. It might be worth checking the settings, because as I recall there are plenty of ways to customise your icon area.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] cropythy:
I am sure it is LTE and not an icon issue, Before flashing PA I was getting 30-40mbps and now the highest data speed I can get it 3-6mbps. If I set the network mode to GSM/WCDMA/LTE (which is what it has always defaulted to before) I cannot connect to a the AT&T network until I set it back to WCDMA preferred. As I mentioned in my previous post it is only this phone, with the Windows Phone I tested using the sim worked fine on LTE. Also as I mentioned this happens on several roms, and has continued after a complete reset to the factory rom using Odin.

Good day!

I found several threads about downgrading from nightly builds to stable versions, but none about downgrade to another, few days older nightly. I've been using the latest CM-10.2 nightlies for some weeks now (using the CyanDelta app to download & install updates), but a since version ...1024... or so, another app started crashing (AntennaPod 0.9.8; upon refreshing podcast feeds; too quickly resuming to be able to take the report option). I'm not sure if the recent nightlies are to blame for this, but I'd like to revert to an earlier nightly.

Therefore, is it possible/safe to downgrade to an earlier nightly, maybe a week old? Or are similar problems to be expected as occur after downgrading from CM-10.2 nightlies to 10.1.3 stable for example?

Thanks for any advice & many greetings!

Cathryne
[Galaxy S II Q&A, Help & Troubleshooting] immortalneo:
Downgrading can be done safely, if you do a full wipe before flashing the previous build. :)

Sorry, for not making this clear before. I meant downgrading without wiping. I know this is necessary for downgrading from nightly to stable, but also for downgrading from one nightly to the one before? Has anybody tried & can share the results?
