had lite'ning 1.4, updated to 6.1, now wifi issues

ok basically i bought the phone second hand with lite'ning 1.4 on it and the wifi worked perfectly ok all the time. Since it was very old i updated it to 6.1. ever since then I have had issues with the wifi. it will connect perfectly fine to the router but i have no connectivity from it, nothing will get any net access at all. This is also not 100% of the time, its MOST of the time but not all, i do have moments where it does work fine. very very odd.
I have since tried updating the kernel to ninpho 2.1.3 from the 2.0.5 that comes with lite'ning 6.1, but that made no difference.
Someone suggested i try a wifi fix app from the market so i downloaded "FXR wifi fix and rescue" and ran that. It ran ok, wiped all my wifi settings and i restarted, but it has not solved the problem at all.
i find it very very odd since if it was a problem with the kernel OR the rom then everyone would surely have exactly the same problem. I know some people report wifi issues but most dont seem to.
anyone have any other ideas?

The odd thing is that it worked before the update. That means that it will most likely be software related.
You could try flashing something totally different like MIUI or CM. They provide kernels too, so this might resolve it, if your kernel and rom don't "like each other". This usually shouldn't happen, but updates breaking wifi shouldn't too. So it might be worth a try.

if i went to something completely different i assume i would have to factory reset the phone to wipe it first? (or factory reset it AFTER installing the new rom?)
was trying to avoid wiping it as i dont want to spend endless hours setting up everything again. i have backed it up with the free titanium but id still like to not have to find out whether the restore actually puts everything back properly
its very odd as its not completely broken, sometimes it does actually work, and it always connects to the router itself without any problem.

Probably wrong modem for you, flash another one. You can find modems in the developement section.

ok thanks I will have a look at that. It is currently on XXKH3 which is what came with lite'ning 6.1. i am confused though, all SGS2 hardware is identical so if this modem in 6.1 is causing this issue, wouldnt it affect every sgs2 that uses that modem?
I found the "shipped modem collection" post in the original development thread so have asked in there which modem i should try.
ok apparently i should try XXKI3. for o2 UK provider.
although i have now read that wifi is not managed by modem but by kernel only. if this is true then modem will not help me

Well, if the wifi is not managed by the modem, try what I proposed you earlier. The simplest would be to flash CM. Make a backup of your current rom, then do a full wipe and install CM.
As for your data:
1. Titanium backup restores your apps with their data (if you wish). That means that, for example, your games will keep their saves, other apps their settings and so on.
2. Assuming that you have a google-account, you don't have to worry about your contacts, calender,... Just sync it before you flash.
3. The backup you make in CWM will backup everything in case CM doesn't work for you.
In case it does work and you'll want to keep it, the other two other parts of your backup will minimize the remaining work. Note that you shouldn't restore "standard"-apps like the media-player or the SMS-app if titanium backup tells you that the app is not currently installed on your fresh CM. This means that CM uses it's own media player or SMS app. It could lead into problems to mix TouchWiz apps with CM.
A side-note:
Don't use the "stable" version. It had more bugs than expected and they made it a RC again. However, it is still in the stable folder. Get the latest nightly.

yep i think it is kernel. just noticed that 1.4 had cf-root, 6.1 had ninph 2.0.5 and i then tried ninph 2.1.3 and both ninph's have had the issue. i just tried speedmod k2-13 as i already had that downloaded and so far the wifi has been ok so hopefully thats it fixed. i guess it was something to do with ninph (i am thinking that because i have it set to sleep the wifi when the screen is off that somehow ninph is not handling this properly).
possibly one good thing to come of it all, ive updated the modem to KI3 which is supposedly the best one for o2 UK so i may even save more battery and speedmod is meant to be really good for battery too. I still have lite'ning on it at the moment.
i might have a look at CM anyway but i do kinda like lite'ning (although i havent actually used anything else since the phone came with it!)
also need to look at wakelocks to see if i can save some more, although not sure how i go about 'fixing' them at the moment

The choice between CM, MIUI and the stock mods is the choice between three different UI's.
I've had all three of them for some time. As you got CWM, you can just create a backup and do a sightseeing tour through the world of custom roms. Believe me, it's absolutely worth it. To get an idea of the main differences, I've written a short overview for you:
Stock mods use Samsung's TouchWiz. The default user interface that you get when buying a Samsung Android phone. So it mostly looks and "feels" the same and you can't do much about it.
CyanogenMod gives you the pure Android user interface. It's the closest to the Nexus phones by google, but gives you some extras. It is much more customizable than stock roms. It's sleek and fast.
MIUI is a whole different story. They're "Redefining Android". I think calling MIUI an "Android custom rom" is an understatement. It's an entire OS. The result of putting the best from iOS and Android into one powerful OS. It adds tons of useful(!) features. If you've ever used Windows Phone 7 or an iPhone, you know what a big step forwards Android is when it comes to features. Switching from Android to MIUI is just like that. There is just so much more. It is BY FAR the most customizable Android you can get.
Wow. If I look at how long the texts are, I see that I'm pretty biased. :O
Well maybe because I've switched so often between them. The stock roms had no chance, because after I used one of the others I found out that TouchWiz doesn't cut it anymore. I hate how "iPhone-ish" MIUI is, but if I flash CyanogenMod I just miss so much. Giving you a list of what MIUI adds would be another long post of this length.

cool thanks will have a look at MIUI at some point.
spoke too soon earlier, the wifi is maybe slightly better on this speedmod kernel BUT when i wake the phone from sleep, it takes about 30 seconds before i can connect to the net with anything. the phone connects to the wifi straight away, but i have no connectivity for a good 30 seconds and then it starts working. (its not the router, i am getting a connection and an IP pretty much as soon as i wake the phone). also the 30 seconds or so only STARTS once i try to connect to something. if i wake the phone and do something that does not want net access for a few mins and THEN try to get on the net via wifi (which shows as connected the entire time) then again i have to wait about 30 seconds from when it first tries to connect before it will start working.

ok slightly confused again.
I have lite'ning 6.1, speedmod k2-13 kernel and XXKI3 modem. I am trying to get cwm installed so i can make a full backup image of the entire phone while i try to sort out the wifi issues. i downloaded rom manager from market, and selected the firstion option in the app 'flash clockworkmod recovery'. it brings up a menu saying 'confirm phone model' with AT&T galaxy S2, a coulpe of i9000s and a plain "Samsung Galaxy S2" which is the one i selected. it downloads something and says successfully downloaded clockwork mod recovery.
i then choose reboot into recovery. when rebooting it attemps to install something but then says "failed to verify whole-file signature" and aborts. so im just stuck with the standard recovery instead.
so now im confused, have i missed something?

Ehhhhm, you don't need to do it.
Have a look at the features of the speed-mod-kernel:
Current features:
Root and CWM:
- Automatically installs root (su)
- CWM 4.0.1.5 recovery
It already installs it right away.
Just in case you messed something up. You should flash the kernel again.
Besides that you don't need the RomManager at all. Just shut your phone down and boot into the recovery with the key-combo. Create and restore backups from there.

[Q] Did any custom rom solve reboot issues?

I agree that each phone might behave differently. But did any one had relief from random reboots after loading any custom rom?
I have tried to format the phone, once even without the memory card but still face the reboot. Some times it goes into reboot loop. Searched on the internet and made changes to the reserved space in Zune as well. But no luck Only thing haven't tried is to load a rom !!!
I have been facing random reboots earlier like once in a day. But now it reboots more frequently, mostly when browsing or switching between apps that connect to internet.
Want to get some suggestion before loading any custom rom that might brick or make some features unavailable in the phone(like i read in other threads).

Some pointers

Some useful pointers
1. Always flash a ROM for your rev. # example: only flash rev 1.3 roms to 1.3 rev. phone because flashing a rom for a different rev. WILL COMPLETELY BRICK YOUR PHONE
2. Always reset phone before and after flashing to prevent further errors
3.Always Backup phone
Im 17 and I have flashed my phone with 0 errors.. If you have a rev 1.3 phone I strongly recommend flashing Clean ROM .. link here: http://forum.xda-developers.com/showthread.php?t=1528984

Thanks for the info. The phone is working fine since last 4 days, i might wait for a week and then go for the custom ROM. Meanwhile, would wait for others to add their experiences or ideas !!!

Hi. Try turning off location services. At least in my case, it was the major cause. I had restarts once or twice a day, now have twice a week. Also try the clean rom. It is much stable than the other roms in this case.

In addition to turning off location services, disable closed apps from accessing internet. You can then re-enable the apps one by one to determine which ones may be causing a problem

Turning off the location service seems to have solved the problem to an extent. Would use the phone for some more days and then will decide on loading the custom ROM as i am little hesitant to change the original ROM.
Anyways, thanks for the replies guys

My phone has never restarted
Hi, My phone has never restarted in particular and i've flashed all possible roms and they all generally ensure a good performance .. May be a h/w issue like my wife's focus which we have returned. Try asking for a replacement if possible.

MDOB rom messed up S4 (full wipe doesn't wipe everything?)

System Specs: Galaxy S4 Canadian i337m OTA 4.3 (jfltecan), carrier is Bell, stock Samsung firmware, stock kernel (use wicked rom 9.1 sometimes too)
WARNING:
lot's of reading so go grab a coffee and have a cigarette before you sit down to read this, you'll probly be here for awhile
The rom/fix in question: MDOB rom/i337m fix - here's a link to both.
http://forum.xda-developers.com/showthread.php?t=2280556
first off i'd like to mention this phone was 100% perfect on stock Samsung rom 4.2.2 using Ktoonsez KT-SGS4 kernel for many months, until the day I installed this dreaded MDOB 4.2.2 rom and the "fix" that came with it
everything went bad on me back while I was running 4.2.2 stock unlocked boot loader and could never get it back to normal so this isn't a issue caused by 4.3 knox or 4.3 itself that i'm currently using. (i'm stuck on 4.3 roms but had this issue way before 4.3 existed)
i'm having an extreme amount of issues AFTER installing the MDOB rom, even after changing rom back to stock (flashed back to stock rom with ktoonsez kernel which is what I was using before I installed MDOB rom and phone has been royaly screwed ever since that day) more specifically I think it happened from the "i337M fix" that's included with the rom, either way after installing this rom I've never been able to get my phone back to normal.
everything runs fine except until I install a custom kernel (Ktoonsez KT-SGS4 kernel) then all hell breaks loose.
I don't blame the kernels or my current rom since I've ran this before for many months until the day i installed MDOB rom on my phone my phone was a dream machine.
issues since this rom has been installed include:
Issues:
A. RANDOM SLEEPS OF DEATH (phone shuts off or freezes)
B. random freezing while trying to turn on phone or enter recovery
C. some kernels won't work proper (specifically ktoonsez KT-SGS4 kernel) example gpu stuck at max while idle and downclocking when screen is touched with this kernel
D. wifi won't work with custom kernel on stock 4.3 rom without build prop edit to ro.securestorage.support, although it should
E. weak wifi and mobile signals
F. bad battery life
G. bad call quality
H. More that I can't remember off the top of my head
here's my flashing process, in attempts to remove as much as possible:
I know a few of these steps are probly pointless but hey can't blame me for trying.
step 1. enable usb debugging & unknown sources
step 2. install root & recovery
step 3. fresh boot phone let files settle so they can save (5mins or more) then plug into computer while turned on and delete everything
step 4. reboot into TWRP recovery (version 2.6.3.1) and clear everything, full advanced wipe, factory reset, format data than clear cache/dalvik afterwards just to be sure
step 5. remove SD card plug into computer and format to make sure there's nothing
step 6. install rom
step 7. (sometimes) clear cache/dalvik/permissions after rom install, although fix permissions seems to break my permissions rather than fix them or maby my permissions just break during flashing and I just can't fix them (haven't tested enough to be 100% sure)
i'm SOOO temped to try a full nand erase since i noticed there ARE still lot's files on my phone directory even after wiping, but i know that isn't a good idea;(
once stock kernel is back on my phone these issues are all gone.
Ktoonsez says it's not his kernel (used to work before, so i have no reason not to believe him), he says it's the rom well i'm on 100% stock Samsung rom (exception of kernel) and the rom was built to act the way it does so you can't really blame the rom so who do i blame??
until i went to go try wicked rom and flash back to stock I didn't realize these things were still on here, but now they emerge! wicked rom was giving me some (unrealated?) issue so i decided ima go back to stock so i flashed stock rom via odin (pc) and right away i noticed the 4G symbol, Samsung wallet, desktop not setup proper (no shortcuts) this ONLY happens when switching from wicked rom to stock rom on the first flash, i flash again everything looks how it should, and in order to get it to do this again i have to flash back to wicked rom and flash stock rom again and BAM it happens.
i knew my issue started on the same day that i installed this MDOB rom but after doing a full wipe and MANY "fresh" stock rom installs later i stopped questioning the rom and just lived with a crap phone that reboots itself all the time and has bad battery life, AS SOON AS I SEEN THE SAMSUNG WALLET bam it hit me like a truck, IT WAS THE MDOB ROM INSTALL.
UNLESS stock Samsung rom comes with wallet preinstalled and hidden on stock/wicked roms than the ONLY other way it coulda got on my phone is from the MDOB rom.
I can wipe/delete/factory reset/flash with twrp & odin on pc all I want, my roms are still messed up after FRESH installs. I believe there is still left over files from this rom/fix, I didn't think there would be anything until I noticed when i'm flashing from wicked rom back to complete stock rom using odin on pc I experience things from MDOB rom (while It should be 100% stock after odin (pc) flash, but it's not)
after the first flash from going from wicked rom back to stock I always experience the following "bug" i'll call it a bug since these things ALL HAPPEN AT THE SAME TIME: once I flash AGAIN all these symptoms go away until I go back to wicked rom and flash back to stock rom than right there after this first flash going from wicked rom BACK TO stock ALL these symptoms come back until I flash stock firmware AGAIN, a second time (even though I just flashed it)
Symptoms:
1. Samsung wallet appears in my apps (this was only EVER on my phone once, when I had the MDOB rom on my phone), this thing shoulda never somehow appeared back on my phone in any way shape or form after ditching the MDOB rom, but again is comes back after the first flash going from wicked rom to stock rom.
2. I get the 4G icon from MDOB rom (not the LTE icon I SHOULD have while on stock, when on wicked rom I have a little LTE icon with a tiny 4G above it, the only time I've ever had just a 4G icon (without LTE) like this is when I had MDOB rom on my phone (which is the only other rom I've run other than wicked rom and stock rom).
3. this icon ONLY shows up after the FIRST flash from wicked rom back to stock, once I install stock AGAIN than it returns to it's normal LTE icon.
4. now i'm not just *****in about an icon here, this is just a part of my problem (indicator if you will), when my rom is "bugged" after first install from wicked rom to stock rom my wifi works normal how It used too. but once corrected (flashing again) AND using custom kernel on STOCK firmware it breaks my wifi 100% broken until I use this little build prop edit fix, set ro.securestorage.support = true to false, bam wifi now working but the rest of my problems are still there (wifi used to work 100% on custom kernels and everything until MDOB rom touched my phone and left this "bug" behind)
5. when this 4G icon appears after this "first" flash back from wicked rom to stock rom I also experience something else, my wifi button works during first boot setup and auto enables itself and I have no issues with my wifi connecting (as soon as I see this toggle on I already know once my phone locks onto the network it's gonna give me a 4G icon and not an LTE icon like it should and sure as shiznit it does, as soon as I get my icon back to how it's supposed to be (LTE icon) all of a sudden wifi won't auto connect on a first boot anymore, never, 100% never. (back before installing MDOB rom I used to auto connect 100% of the time on first boot) like it does now only when it's "bugged" out.
6. apps are missing, when this "bug" appears there's no app shortcuts on the desktop of my phone by default after fresh flash like there should be, sometimes they appear on first flash once in awhile (some apps might not even be installed? or just shortcuts missing, have yet to verify)
7. it feels like the phone flashes way too fast (second flash takes longer, I think?) and more/all? apps get installed on second flash, and Samsung wallet get's REMOVED (how'd it even get there? other than bein left behind from MDOB rom, same with the 4G icon, that icon isn't in either of the two roms I use so how does it get there? and ONLY at the same time the wallet magically appears and the rest of this stuff)
8. when this 4G icon appears my phone seems to be great except for the fact that I know my rom didn't install properly since i'm still missing apps ect, once I flash again, apps appear, Samsung wallet DISappears, 4G icon gets replaced with LTE icon and everything is A-OK until custom kernel is installed, remember this is NOT the kernels fault as it ran 100% perfect for many months ON THIS PHONE until the day this MDOB rom was installed, and it's had these issues ever since.
some of the things I've tried:
- Countless wipes, including full advanced wipe, restore to factory, data wipes
- Ton's of fresh installs of BOTH versions of 4.2.2 - now doing same with 4.3 and wicked rom 9.1
- Tried wiping using TWRP and odin mobile (flashed mobile odin via TWRP, it works incase anyone didn't know)
- Tried flashing roms using odin (pc) v1.85, v3.07, v3.09
- Downloaded new copys of roms from new sources to make sure my roms weren't corrupted in anyway
i'll hopefully edit this post and get some pics up soon and simplify my text to help you guys better understand my situation and i'll also add a list of things I've tried to fix this problem when i have time.
any thought would really be welcome, there's sooo many of us s4 users with random sleeps of death, i'm sure if we could fix this it would help out a lot of S4 users.
thanks, dustin

Have you tried to flash the stock firmware in Odin. You can get it off the Samsung Updates site.
The guy who puts MDOB together generally makes great rom's. If everyone had the same issues then no one would use it... you really could have gotten a bad download, user error somewhere or one of many other problems.
With apps' just "appearing" are you certain once you log into your google account that it not set up to automatically start downloading apps ?

don't get me wrong, i'm sure it's a great rom but my battery drain was worse than stock so I went back to stock, I REALLY appreciate his hard work towards our community. I just dislike what it possibly did to my phone is all.
and I don't have issues with the MDOB rom itself, it's AFTER that rom has been on my phone EVERY other rom ever since then now has issues in some way shape or form, no matter what I do.
if it's user error I put down the steps on how I flash in OP, I dunno what's going wrong
i'm gathering screenshot's to better show my situation.
I am 100% positive GAPPS is NOT installing anything after rom installs (I don't connect to wifi until after setup is done spacificlly to prevent this from happening, my rom just flashes this way (only on first flash from wicked rom going to stock rom) once I flash again a second time my symptoms part goes away and I get the issues part of my OP
if i'm on wicked rom and flash to stock = symptoms listed above
if i'm on stock rom and flash to stock = issues listed above
I can replicate this problem all day long.

I've flashed his rom on and off. Never had the issue. The rom doesn't invade anything a full wipe wouldn't cure. If it doesn't full wipe then it's the recovery. It helps once in awhile if you Odin back to stock or even copy your sdcard contents and format your sdcard to make it fresh. read up on it first.

Also I recommend doing 9 wipes when swapping roms. It sound ridiculous I know but I do it and have never had issues.

Just odin back to stock and set if that clears things up. It should solve any odd problems. The thing with flashing rom's is that someone's issues cannot always be replicated.
Going back to Odined stock will take it back to factory stock then do a factory reset in stock 3e recovery and you should be fine

[Q] (Q) Screen stays on when I miss phone call or msg

Hello.
I posted the question in the Q & A thread but I fear my question got lost in between the many that are asked.
I own a rooted S4 from Rogers Canada, which used to be on Alpha Infamous rom, an old version like the 5.0 from at least 6 months ago. Everything runned fine until recently. The phone started giving me some trouble. After missing a phone call while I didn't had the phone on me, the screen stayed on showing missed call until I happened to see the phone and pressing power to close it. The same started happening with message at about the same time.
Since I thought I might have installed a dumb apk on gplay that messed something in the settings, I went to get a new Rom. Alpha having no development for a long time, I thought I'd try something else.
I have tried both omega v25 and [23/03][4.4.2][XXUFNBH]< Echoe v18 > [07/02][4.3][NA4]< Echoe v12.1 "The Final Bean">, the latest which I run at the moment. Both gave me the same trouble with the screen staying powered after missing a msg or a phone call.
Since I don't know how to fix it, I was wondering if anyone could help me out ?
I'm no pro at rooting/flashing but I did the wipe dalvik, cache and everything before flashing both of the new rom. I didn't update the bootloader as I didn't remember clearly how or if it was necessary but the rom in general runs great so I figured out it was ok this way. The only trouble I have is with the screen as previously stated. I didn't flashed the modem either as I seem to have great download speed (without testing, simply feeling it).
So as of now, I'm running Echoe V18 with most of the bloatware disabled in aroma installer.
What can I do to fix this? I've tried googling but nothing close to my trouble came as result. Neither could I find an answer here, there's so many result I might have simply missed it.
Thanks for the help!

Anyone's able to help out ? My question is getting phased out but still has no answer. Please ?

Refresher on world of custom ROM's

Hi all
I have a Samsung Galaxy S5 G900F, which when I got it 18 months ago was very eager to get involved in rooting and getting a custom ROM on it.
Fast forward to present day and the novelty has worn off, I haven't kept up to date with anything, and I am probably very out of date.
As such I would like to either update to the latest ROM or just flash the latest stock - I am not sure I really use much nowadays that even requires anything other than stock (used to play a lot with Tasker, sysadmin apps)
What has prompted this is of late my phone has been very laggy, crashing, sys apps hanging, etc. I also dropped my phone ages ago and occasionally the screen stops working (although still responsive) and I have to take the battery out to get it back (sometimes it reboots to a full screen of coloured static, and I have to repeat this several times). Now I know this seems like a hardware issue but at times the phone will not have been touched or moved and it'll do this, which makes me hope that maybe updating it will help.
I have a paid version of Omega Files Pro but apparently there has been no update for a very long time.
Hopefully you guys can help me get back up to date and on a level
Android Version: 5.0
Baseband version: G900FXXU1ANCE
Kernel Version: 3.4.0-Omega-1.0
Build Number: Omega V17 - XXU1POCF
I have PhilZ Recovery iirc.
Thanks in advance, if you need anymore info please say.

Install the rom from alxndr thread. Its a stock rom slightly optimized. It is the best for stability, performance and battery. There is only great reviews about it, it has a great community, and he updates it very frequently.
He has roms for either android 5 or android 6, which could can find in the second post of the thread.
If you choose to install android 6, you will have to update the bootloader and modem. They, as well as instructions, can be found in his thread.

To correct the issues, you will probably need to perform a full factory reset before installing the rom. Before anything, I recommend you to do a full rom backup (using your recovery). That way, if you forgot to backup something (like your taskers profiles), you can always go back.
Before doing the factory reset, you should backup your SMS, calls and apps. The easiest way to do it is by using the integrated backup tools in your S5 options : in the backup&restore sections, you will find a Samsung section that can backup messages and phone calls. There will also be a Google section where you can choose to backup your apps. If everything is set up correctly, once you will boot the new rom, you will be asked sequentially if you want to restore the samsung (Messges, call logs) and google (apps) data.

Thank you I'll have a read.
