[Galaxy S 4 Q&A, Help & Troubleshooting] flexyneat:
So i have a week old galaxy S4 and everything is fine until i realise that it only sees and connects to my 2.4Ghz SSID. I use a dual-band sitecom WL-309 extreme gaming router. My laptop, ipad and galaxy tab can scan and connect to the 5Ghz SSID. I'm really surprised that a phone that boasts 802.11ac isn't even able to see 5ghz wifi. i recently installed the wifi analyzer app, and it doesn't help, can only still see 2.4.

I recently upgraded my firmware to the indian MEA stock ROM. Dunno if anyone out there has experienced this, help apprectiated.

Thanks

I saw in a post that wifi channel may be the problem, my router has the following 5ghz channel options: auto,36,40,44 and 48. Just tried all and still no joy.

im having the same problem exaclly.

i cant see any 5Ghz network at all.

i tried replacing channels on my router and still. cant see.

I have an AT&T galaxy s4 that will not boot up. I tried to flash the ROM and install SlimBean 4.2.2 build 6. after it was installed and everything, the screen went black and will not show anything. It wont go into recovery mode and vibrates every 5 seconds whenever i power it on. i tried to flash the stock rom using odin, but that didnt work either. somebody please help!

I'm unable to get into recovery mode or boot up the device. I can only go in to download mode. Any attempt to boot up the device or go in to recovery mode results in a blank screen and small vibrations every 5 seconds.

this all started after i attempted to flash SlimBean on to my US AT&T Galaxy S4.

can somebody please help me? im desperate and need assistance!

If you can go to download mode you can Odin back to stock. There's tons of Odin guides. I can't link because I'm on mobile but I'm sure you can search. As long as you have download mode youre not bricked and all is fine. Just be sure to have latest Samsung drivers installed for your PC.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] scott14719:
It sounds like you tried to flash a ROM or Kernel that is not intended for the AT&T S4 and bricked your phone (screwed up your partitions). If so, you might want to look into JTag repair services. There is a PIT file available for the 16GB version of the phone but I wouldn't touch it if you don't know what you are doing.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] HackAttackXx:
Odin is working fine, and whenever i try to flash it back to stock, odin says that it passed, everythings good, etc. But then when phone reboots, it just stays at that blank screen and keeps vibrating.

And could you refer me to a guide or something on PIT files or JTAG services, please?
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] AxAtAx:
Exactly what he did, looks as if he flashed the incorrect kernel.

Odin is the answer.

pull your battery and wait a few seconds. place the battery back in and immediately press the recovery button combo (vol up + home + power. release just the power button when the device vibrates and you see the blue script in the top left corner).

if this gets you into recovery, wipe data and cache. reboot.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] joeybear23:
In Odin are you using the phone option or the pda option?

Please make sure you follow the Odin instructions exactly to the T.

in Odin im using the PDA option, just like all of the threads and guides said to do.

and i tried the recovery combo a few times, nothing showed up. it just kept vibrating like before

I'm having the exact same problem, seems like I did something similar (i.e. install the wrong kernel). Any help/assistance would greatly be appreciated
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] plwalsh88:
You guys need to start providing links to exactly what you flashed. How is anyone supposed to know if it really was a "wrong kernel" or if it was a seemingly correct kernel that people should stay away from?

Edit: sorry, not you HeartAttack; I know you did.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] HackAttackXx:
i did earlier. i tried to flash slimbean on to mine (http://xdaforums.com/showthread.php?t=2292474) which is under the AT&T GS4 section, so i thought it wouldve been compatible. i was obviously wrong.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] xFierce:
So this is what happened to me:

I flashed the foxhound rom (link) using CWM, (Wipe data, clear cache, & clear delvik cache. It installed perfectly, but because this is not an AT&T rom, I was having wifi issues.

Rather rewiping the data, clearing all caches and reinstalling the rom and then the ktweaker kernel, I just installed the ktweaker kernel (link) that I got off from galaxys4root.com.

This was my first time using this kernel with this rom. Since it was an AOSP rom I uses this kernel because it was also AOSP.

So now I'm stuck in this cycle where my phone vibrates every 3 seconds on a blank screen. I can enter download mode and I have used odin to flash original stock firmware, but I come back to this same issue every time. As OP mentioned, I am also not able to access CWM recovery after holding down keys to enter recovery.

NOTE: I believe every time the phone vibrates (every 3 seconds), the phone itself is rebooting. Therefore I don't have enough time enter recovery.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] plwalsh88:
I would venture to say you are correct in that it's continually rebooting itself. Maybe it's some sort of bootloop at the kernel level since it's before the OS splash screen. I duno, but this seems to be the way S4s are bricking. Every report I've seen so far over the last month and a half has mentioned being able to get into download mode, Odin passing but not working, not being able to make it to recovery, and the 3 second intermittent vibrate on a black screen. Someone should start a thread to try and collect all the different accounts and work towards a diagnosis.

I can't think of any reason why flashing that kernel would cause this, though, since everyone else in the KT thread seems to be okay. The only thing I could think of is that website you downloaded from is a little suspect. You should download everything directly from the source in an xda OP, or sammobile for stock tars.

FoxHound is a TouchWiz (TW) based ROM. So at least we know you're problem. AOSP Kernel on TW Rom.

That'll do it every time
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] scott14719:
I have a theory...but just a theory of what is happening.

I think it is related to the write protection that exists on these phones. I think what might be happening is people are flashing the wrong kernels onto their phones and screwing up the partitions. Normally, depending on which phone this occurs on, it might be fixable or it might cause a brick. The difference with the AT&T (and maybe other S4s) is that several levels of write protection exist on the phone. Not necessarily the locked bootloader, just the write protection.

Anyway, the combination of the screwed up partitions and the write protection are creating a somewhat unique condition in which ODIN reports successful flashing of the stock firmware, but it actually doesn't flash.

If you check in the Dev only forum...

http://xdaforums.com/forumdisplay.php?f=2321

...there is a thread in there about "Manually patching files with OTA patches". I didn't directly link the thread because it is a DEV ONLY SECTION! And I don't want people reading this thread to jump over there and post unless they are Devs. Anyway, in that thread it explains a similar problem caused by the phones write protection that makes it appear things are flashed successfully, when in fact, they are not.

Maybe this isn't the issue, but it is just a theory I have.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] acruxksa:
I haven't messed with Odin since my Atrix 4g days so I don't know if there's a way to get odin to flash the right kernel. Is ADB and option? I wouldn't know because I try my best never to need either.

anyway to flash an aosp rom sans kernel on the phone with odin or adb? Then perhaps he would at least have an aosp rom to go with the aosp kernel. Just a thought.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] HackAttackXx:
that was pretty stupid of me, and ill make sure to stick with these two sources from now on.

so we either have to wait for a solution, replace the device, or use the JTAG service?
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] plwalsh88:
Good catch. I just took his word for it since it was an i9505 ROM. So next time, Fierce, you might wanna read the OP a little more carefully rather than just flip through all the pretty pictures.

As of right now I don't know of any other resolution besides JTAG, which mobiletechvideos will do for you for $60.

---------- Post added at 06:20 PM ---------- Previous post was at 06:11 PM ----------

I like your theory, Scott. Seems very possible that something like this is happening. The only thing is that I'm not convinced it has anything to do with the partitions. Because flashing an AOSP kernel under a TW ROM shouldn't change the partition table because the kernel was still made for this device. It was still an S4 kernel, not like an S3 or something. But if I recall correctly, doing such a thing on the Skyrocket only caused a recoverable soft brick (I could be mistaken though). And the weird thing here is that this is technically still a soft brick. Because the device still functions -- tries to boot, vibrates, gets into download mode -- they just can't recover from it. I think it's the screwing of the partition table (flashing kernel for wrong device) that immediately caused a hard brick, write protection or not.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] scott14719:
Yea, that sounds right. A way to test it would be for someone in this situation to flash the pit file through ODIN (must be 16GB version) and then try to re-install the AMDL firmware via ODIN. The pit file is available in the Dev section. Flashing the pit file should erase all memory on the phone and reset the partitions (if it works). Of course, there is all kinds of risk involved at every stage, but if someone is going to send their device for Jtag repair anyway, they should have nothing to lose. There is always a chance that the write protection might not let the pit file properly flash either.

But it would help to confirm if the pit file available for this device works properly, and, if it does, if the write protection is preventing either the pit file, the Kernel, or the stock firmware from flashing on the phone.

OK, so who is currently in this situation that is willing to try this?
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] plwalsh88:
Has no one in the Dev section actually tried the pit file?
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] scott14719:

...I have seen many requests for it, but have yet to see anyone try it.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] xFierce:
Okay so I flashed the .pit file and the AMDL firmware through ODIN successfully, as shown here. I did not encounter any error through ODIN, but needless to say it still has not fixed the problem. I'm still on a blank screen with vibration. I'm willing to try any other reasonable solutions before I give up. And again thanks everyone for catching my mistake, next time I'll make sure I pay attention every detail. I still can't such a silly mistake caused so much stress.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] plwalsh88:
Thanks for trying, and giving us an update. Hopefully someone can come up with another option for you to try.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] scott14719:
Yea, thanks. I think ODIN is reporting the install as successful, when, in fact, it isn't actually flashing the files to your phone. That is why there isn't a change.

Another thing. I wonder if you can flash the stock (3e) recovery through ODIN to your phone. Not the entire firmware, but just the stock 3e recovery? This would require someone to extract the original recovery and have it available in a TAR. I'm not sure this exists for this phone yet? I know it has been possible for other phones. A lokied version would work if you could get to your custom recovery, but because you can't, a lokied version will do you no good it will have to be the TAR..

Also, can you access your phone via ADB? Is your phone recognized as an ADB device. There is information available about ADB in the forums. I am wondering about ADB because I think ODIN might be useless to your phone now. Somehow, write protection just isn't allowing files to be installed on your phone. Maybe ADB can be used to push the stock recovery to your phone?
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] plwalsh88:
As I was making my way through your post, I started thinking about ADB, and then I got to the end haha. I duno if the device will be recognized as it's trying to boot up, but maybe once it's in download mode, since it's in a stable state, it could get recognized. And then possibly from there try a reboot recovery command?
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] scott14719:
OK, it seems that a couple of people in the 'ODIN return to stock" thread had a similar problem. At least one of them was able to get into recovery, but they said it took several attempts and was extremely touchy. Here is a post about it the key sequence...

http://xdaforums.com/showpost.php?p=42297611&postcount=198

The only thing different is that I would let go of the power button as soon as the phone first vibrates, but hold the other buttons until in recovery...if it goes into recovery.
[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] xFierce:
So I basically gave up with ODIN and the whole process of restoring my phone. I went back to AT&T warranty & repair store and they were able to swap me another phone (refurbished/recertified) since everyone who buys a new phone from AT&T is guaranteed a 1 year warranty. Of course, I didn't mention what exactly happened, as I stated that it merely stop working. The service rep did try to see if it entered download mode, and then told me he couldn't do anything to fix it and I ended up getting a replacement for free. So if anyone is in this chaotic moment as I was in, keep note that you are able to swap your current phone for another.

I am in the same situation with the same slimbean. Our ATT store does not open until Monday so I am willing to try stuff on it. I got it not this past friday but the one before that, so I can hopefully slide it off as a device that was slow and eventually quit working but it would be wonderful if we could possibly find a fix. I am downloading SDK now to see if I can see ADB in Odin. I only got tonight and tomorrow so if we can hustle lets do it :). It cant get no worse than what it already is. Is it not possibly to flash a kernel? If that seems to be the cause?

[Galaxy S II Q&A, Help & Troubleshooting] guidostein:
Hey first of all I'm sorry if this is already somewhere on XDA but I really need help.

I have a Galaxy S2 model number SGH-i757m, and I'm trying to root it but I cant get my computer to recognize it.

When it is plugged in it shows that it's charging but it doesn't connect.

I'm using a Mac (if it makes a difference). I've heard that heimdall can screw up your USB ports is it possible that that has happened to me?

I did try it on a different computer and still no luck. I was also wondering if it could possibly be the cord. (I'm using a stock samsung USB cord)

Any help is appreciated.

Thanks
[Galaxy S II Q&A, Help & Troubleshooting] MistahBungle:
Yes, using a Mac makes a difference. Not from my personal experience, because I've never used one, but from the experience of people on here. People on Macs who post here invariably seem to have problems. I doubt Heimdall can 'screw up your USB ports' tho. That doesn't sound grounded in logic even remotely.

If you're having problems at this early stage & want to make life easy for yourself, get access to a PC. Once you root your phone you won't need either the Mac or a PC (because you'll be able to use CWM) unless you end up with a situation where you need to use Heimdall/Odin to recover.

Edit - There are a bunch of troubleshooting steps which people on here try if Odin doesn't work, I'm sure many of them apply to Heimdall not working as well; search for recent threads where Odin isn't working for people & try those steps (I believe Hopper8 is the most recent person to post these steps in their entirety about a week ago, so searching his posts should help you narrow it down).

I got my ZL yesterday applied the international firmware with flashtool everything was working fine, but then i noticed that wifi disconnects randomly all the time. Today when I went to work I tried to test the Mobile connection but it also just shows the "E" "3G" "H,H+" sign like 6 seconds then goes blank and i have no mobile data, could this be a firmware related issue or a hardware one?
[Sony Xperia ZL] butatx:
For the mobile data, i think it is how the mobile data work, when there is no use of data (downloading, syncing) the sign will disappear to save power consumption. When u need the data it will show the sign back.

For the wifi, sony OS for ZL sometime suffer this low connectivity range. You can try to repair using PC Companion if you want. Before this i'm using Incredible S and suffer wifi connectivity loss frequently, i can't finish any download but when connected to other wifi it has no problem, the solution is to change ur wifi modem channel, then the problem solved.

For sony there is solution by altering your build.prop (in Z forum, i forgot the thread) but some user said that it will drain ur battery quickly. I never test it.
