Hi, My SGS4 has never really worked since new. I experienced the same problem as this person when I got it last year, ie, it loses signal and then latches off and needs to be rebooted or put in and out of flight mode to nudge it back to life:
http://forum.xda-developers.com/showthread.php?t=2288744
I've tried lots of stuff the operator suggested and replaced the SIM etc. etc. In the end I got fed up and swapped back to my SGS2, which is works fine, and intended to swap the SGS4 for another one. But since moving to the SGS2, the the 4.3 OTA update has been released. I've NOT moved to 4.3 and it comes up with the new software available message every few hours.
On all my other Android devices I've rooted them and to make use of TiB and other neat tools. I haven't done that with the SGS4 yet but would like to once it's out of warranty.
So my dilemma is this...
Should I send the SGS4 back and get another from the operator and risk getting a 4.3 KNOX device, or
Should I send it to a Samsung service centre (as folks in the thread I referenced suggest) and risk that the service centre updating my phone to 4.3, or
Should I root and update to 4.3 without updating the modem etc. to avoid KNOX and see if the new OS fixes my problems but risk my warranty (which runs until May 2015)?
I'm kicking myself for not getting on with this months ago before 4.3 was released. Any views gratefully received.
-Thanks

Hi,
I take it that you have a pre-knox bootloader.
Me too.
I installed a custom recovery and only used custom ROMS/kernels , so I remained on the old bootloader.
At any time I can use Triangle Away and flash a stock MGA firmware to return to it's original state.
I can flash knox-free ROMS and modems and it still does not affect or change the bootloader.
I suggest you try the same.

Hi!
I remember that in the S2 or S3 i was able to flash stock roms taking out the bootloader and/or that there was a user that did that for us an posted them...
Is it posible to do the same thing on this phone ?
I would need this because my girlfriend has an S4 bought in "personal" (argentinian carrier).
Her display started failing in the red and blue colors, it was a mess (3 months old phone), so i had to flash back the 4.2.2 firmware that came with it.
For some bogus reason, we can't get warranty if we swap it for a newer one that is not from the carrier... (warranty is taken care by samsung, but since the invoice is from "personal", they check that)
She is now on the newest 4.2.2 rom, and she got the OTA warning for 4.3... she almost installed it
Hello Guys
Well, let me get straight to the point. After my old rom (Revolution HD3) was draining my battery pretty fast, i decided to update to 4.4.2. Well, i downloaded the latest 4.4.2 for switzerland from sammobile.com. I flashed it and it somehow was all laggy and i had fc's the whole time. After some time i was able to use the phone anyway, but it was laggy. And the problem was that my 3G connection was EXTREMELY slow. I got connection time outs the whole time and wasnt able to download anything. Well, i thought it was the rom i flashed trough odin, so i downgraded to 4.2.2, my original rom, and updated trough KIES. The rom wasnt laggy anymore, but the 3g/4g was slow. I tried different Modems and Kernels. Nothing Helped. I then decided im going back to a custom rom but the flash failed. Then i tried another rom and it failed again. So i thought it may was cause i was on 4.4.2 and tried to flash a custom rom that was 4.2.2. I then tried to reflash my stock rom trough odin, and it FAILED. And that's how i bricked my phone. I can still enter Download Mode, but can't enter the recovery anymore. What do i do? I'd like to solve both problems.
Thanks guys
Btw: I've got an I9505
I assume you didn't wipe anything before you flashed stuff? Thats like rule number 1 to do.
You can try flashing a recovery true Odin.
Hej Guys
Um.. Just to let you guys know, it is possible to downgrad to 4.2.2 from 4.4.2. I just did it this morning and had sucess. But the problem with the really slow internet connction still is here, when im on a 4.4.2. And, it is the same with custom roms running 4.4.2. I tried different kernels and modems, nothing helped so far. As soon as i was back to 4.2.2 it had the usual connection speed. I called my provider and also called samsung itself. Obviously, they both told me to bring the phone back for garantuee. But well, as i know it's a software problem and not hardware, i wont do that. So can you guys help me? What should i do next? Actually im back on 4.2.2. Thanks
Edit: Oh, and ofc, i did everything like wiping/factory resetting, wipping preoload etc. It's not my first time flashing.
It's not possible to downgrade from 4.4.2 to 4.2.2! End of..

Are you serious dude? Im running 4.2.2 right now. What is your point?`I didnt even ask about it. I asked about a solution to the problem that i get slow 3G/4G on my I9505 when running 4.4.2. If you want a proof Pic about it running 4.2.2, i can give you one. But i dont really get what your point is.
Hang on hang on hang on, it is common knowledge that you cannot downgrade from official samsung 4.4.2 to official samsung 4.2.2 because in odin you will get failure at aboot.bin because you cannot downgrade bootloader.
How ever what would be really good is instead of just trying to say it then jumping out saying what's your point, we'll my friend the point is, it would be advantageous to everyone in the entire samsung galaxy s4 i9505 community if you can tell everyone how you did it.
My perspective is your doing a bit of flaming.
Pictures really won't prove a whole lot as anyone can do some build.prop edits and show different rom name and version.

Well, if it sounded like flame to you, it wasnt. I didnt create this thread to flame others. But i wasnt kidding saying that i downgraded to 4.2.2. Here how i did it:
Was running 4.4.2 (I9505XXUFNB9)
Flashed TWRP recovery.
Flashed custom Rom 4.2.2, which FAILED!
Flashed Official 4.2.2 trough odin, which FAILED!
Flashed TWRP recovery again, since it was somehow damaged from the flash before
Flashed Wanamlite 4.4.2
Flashed Custom Rom 4.2.2
Flashed Official 4.2.2 with succes.
Im not sure what part of those flashes were essential, but i have no reason for liying to you. What would be the perks if i did?
But now again BTT, Did anyone else have that problem of slow interenet connection? Or is it just me? Maybe some ideas?
Regarding slow Internet maybe it's your carrier with issues.
Maybe the downgrade back to 4.2.2 has created issues in its self. Have you checked your baseband matches bootloader and build?
A problem we have is we can't see the version of the 4G modem (non-hols) so that might be also an issue.
When you flashed back did you do a factory reset?
In regards to downgrade do you still have the Knox bootloader?

Well, i called my operator and the girl on the phone said that some people already called with the same issue, but its not on their side. It's a problem with the update samsung released. After the downgrade i had my Knox Bootloader and everything worked like it always did.
Yesterday Sammobile released a new ''rom'' for my country. Downloaded it, flashed it and it works great now. I have a bit of a fast battery Drain, but the problem with the slow internet seems to be fixed.
Again: 4.2.2 worked perfectly after downgrade. It had no issue, No FC nothing at all. Maybe i was lucky? No idea, but im happy my 4.4.2 works now
Thanks anyway for your help guys
Edit: Yeah, my bootloader matched both baseband and build.

If you had done your homework, you would know that in almost all cases Samsung repairs it even with Knox set to 0x1. They even publicly stated it in the Netherlands that they will repair your phone even with custom roms.
And you don't know the law in Switserland. Nor do I. So you can't say that in Switserland his rights are voided by flashing.
If Samsung doesn't give you the warranty, then you still have your consumer rights in the European Union (not that Switerland is in it). No flashing, modding or other chances decleine you your rights if it's not related to a hardware failure. In the countries that you and I live in, it will never void your rights if the damage is not related to flashing or modding.
So well, i think that in switzerland they actually WONT repair it if you flash it, but i aint sure about that, since i never had to send it to repair. But anyway, it was only a software problem on their side. They released another version for switzerland and it seemed to have fixed the problem. I have a bit more of a battery drain, but i actually think im just too used to some other custom roms. Anyways, thanks for the help guys
I got my S4 about a year ago, and it came loaded with MF9 / 4.2.2. I rooted it and added the hotspot hack and have generally been pretty happy with it. I know there have been a handful of updates in the past year that have likely introduced new features but I know there are also new restrictions. I keep wondering if I'm missing anything significant by not upgrading. If I did, I'd probably err on the side of caution and go straight stock NAE.
So, any good reason to upgrade? I've been away for quite a while so appreciate your input.
Do you have knox? Cause if not never upgrade.. If you do.. No reason not to upgrade
Nope, no Knox, which has been my major hesitation because I know there's no going back. But I'm also falling further behind while stuck at MF9, which perhaps isn't such a bad thing, but I get antsy knowing there's been several releases since then.
My bootloader is mf9...But all my software and modem are up to date.
So i have android 4.4.2 and NAE modem.
So i am away from knox. All things are working well.
But i want to flash the full stock via odin and trip my knox counter since I will root my phone and also can flash custom recovery but the only thing i will miss if i decided to return to previous version of Android i can't do that.
So i won't see behind. I will flash anything new.
U have the holy grail of sgs4s dont go and ruin it. Keep bootloader flash twrp and rock a custom rom. Updates are only put out to destroy you and rape your gf.. Your not missing anything. To my knowledge bootloader being old only limits the STOCK roms you may use. (please c9rrect me if jeeded)... In my experience in 33 years i have never gained anything by upgrading a firmware on anything phone psp xbox router u name it.. Nothing but loss of hackability
Hello!
Today I had a really weird situation with my Samsung Galaxy S3 Neo !
I put the phone on the charger as usual, then went to sleep.... Only to wake up on the boot intro sound of my device several times!
The only obvious reason for this situation is probably just putting my phone on the charger!
I tried to reboot several times, removed the battery and waited for a while, but in vain! Sometimes I had the logo screen, very slow one with a stuttering audio, sometimes not.
I tried to flash stock Kitkat firmware 4.4.4 (the same Hong Kong one I was using already)... No change!
I couldn't boot properly into recovery till I decided to flash TWRP and do a full erase of just about everything that could be erased!
The result?? You guessed it... NO CHANGE! Still the same bootloop, while sometimes I could see the launcher before the reboot!
I decided to try to flash the previous firmware that was before the update (4.3 Jellybean, UAE) and send it to the service center, and I just removed everything from the phone: The battery, and all the cards were removed and put aside! However, I found that this will trigger the Knox Warranty flag to 0x1, definitely not the best shape for visiting the service center! :\
After all, I decided to give it one last try to boot before I send it to be serviced just the way it became. To my surprise, I managed to boot successfully and restore almost everything. The only noticeable loss was the Samsung "Over The Horizon" soundtrack! (Got links for this one, please??)
However, all that flashing wasn't for free! I had a change of both firmware statuses to "Custom" after I had a once "Official" firmware tag! To my chances, I didn't trip the Knox Warranty Flag, and I had my device rooted using CF-AutoRoot with Odin!
A few questions here:
1. What the heck is going on?! What caused all of this from the beginning??!! The phone was rooted and working great before that! I even managed to resolve the battery drain and the camera issues for good! (I'll describe my method later )
2. After all that play, how come I didn't trip the Knox flag?! Was it just... luck???!!!!
3. Can I change to the UAE firmware from the Hong Kong one without tripping the Knox flag???!!! I have little problems with the Hong Kong one, despite the fact that I had some crashes and minimal glitches before! As you all know, Android is a glitchy OS, but this one has much less glitches than before.
Thank you for your time. Hope to see your thoughts asap
Question 1: I read similar problem on samsung phone somewhere caused by defective or dirty microUSB connector. Perhaps your several flashing resulted on dislodging of the dirt from the connector thus your reboot problem was resolved.
Question 2: I also flashed 4.3 over kitkat from hongkong rom and the knox was not tripped. Perhaps only rom 4.2 and below will trip the knox?
Question 3. I have done flashing from Hongkong to UAE to Russia no problem with knox.
Good luck!

Thanks a lot!
BTW, which one is better to use of the three firmwares you flashed already?? I have the I9300I with the 1.4 GHz Quadcore CPU and I know that some firmwares are made for the 1.2 GHz edition...

You may have read my experiences with kitkat on a separate post? I am back to 4.3 now.
Anyway the most stable among the 3 is the latest Hongkong kitkat. Some users here suggest Kazak rom but I has heating problems with that...
Hi everyone ! I have my s4 for like 4-5 months and i still didn't get the lollipop update, i'm frustrated because i have a lot of friends who have got it and mine says "The latest updates have already been installed" . I just flashed stock 4.4.2 firmware so the device is CLEAN. Any ideas ? Should i try to flash 5.0 directly ? Are there any risks?
Samsung rolls its updates out based on region, carrier and production date, it's normally a few months before everyone gets the update. The update's been ready for quite a long time, but even mine only got it last month. Sit tight!
As to flashing, well the risk is bricking your phone.
I know that, and the fact is all my friends are on the same carrier and they got the update months ago. I strongly thinks it's my phone the problem.
No one wishing to help ? I'm sure it's something wrong with my phone, but i can't say what, i am just a noob. Last time i flashed some 5.0 CM firmware, then when i flashed 4.4.2 stock, i had lost my IMEI or something like that, i had to search internet 4 days to 'repair' it. It may have something to do with it. PLEASE help me ! If you won't help i will flash it manually w/e.
You can flash via ODIN, there is no risk and its virtually impossible to brink the S4 if you read well and perform everything according to instructions.
My i9505 was originally from Austrailia - Vodafone, and AFAIK it still has 4.4.2. Thankfully, my phone wasn't carrier locked so i was able to safely flash 5.0.1 of another region and its working perfectly for a long time now.
Flash there's no risk

I had your same problem. All my friends got it in December but I Didn't get it. So I flashed the stock Russian Rom which was the 1st one to come out via Odin. So there was no issue only google now didn't work as it is banned in Russia. Finally after a few months samsung released it for my country and I flashed my country update over Odin and google now also returned. Flashing via Odin is the best way to receive the update for impatient ones like us (oh and don't worry once you flash your country Rom back you will also get OTA updates as normal) l
