Bootloop! Need help, please! - Galaxy S 4 Q&A, Help & Troubleshooting

Hello. This morning I decided to install a custom ROM on my S4 i9505. I installed Clockwork Recovery, installed CM12.1, but few hours after, I decided to go back to stock ROM, which I backed up entirely through Clockwork. After everything was restored, I booted up and my phone was stuck at SAMSUNG glowing screen. I managed to go back to recovery and tried to reinstall CM12.1 from backup but that didn't helped me eighter.......CM12.1 gets stuck ever earlier......at Samsung GT-i9505 screen and shows on top of the screen "kernel is not seandroid enforcing". What should I do now? Is this a "pretty" common problem or I'm fked? In this situation can I flash back stock ROM through ODIN?
Thanks in advice,
Andrei.

Solved bootloop, but now there is no Wi-fi
I've solved 1 stupid I did, I need to solve another one. I've told you guys that this morning I've installed Clockwork recovery. Now my Wi-Fi is not working and I think I changed the kernel this morning. Anyone can help me?
Thanks in advice.

Flash the ROM again. Sometimes it takes a couple flashes for the modem to properly work.

Wi-Fi won't turn on

Just got a brand new i9505 and the Wi-Fi won't turn on.
When I hit the Wi-Fi toggle it goes on for 1 sec then back off. I have tried a factory reset etc but just can't turn it on. I can't believe it's actually faulty. This is my 2nd faulty S4 out of the box. I brought a i9500 about a month ago and it keeps freezing & rebooting after a minute of use. Unfortunately I can't send that one back as it has a custom Rom & there is no way to reset the counter. I gave up on it and through it in the draw.
I decided to get a new one but went with the i9505 this time. How can I have so much bad luck. Is the S4 that unreliable?

I had the same problem with a custom rom wifi won't turn. All i did was change the kernel.
Hope this will solve your problem.

Instead of clicking the wifi toggle, why not try to go into settings and mobile networks
and turn it on there.
Good luck!

I,m using KERNEL][INT'L][AOSP/TW][6/10/2013B] KT-SGS4 - MDM - KTweaker
You can try booting into recovery and clearing the Cache and Dalvik Cache to fix the wifi. It's worked for me and other people on this forum.
i also have the same problem on my S4, basically the wifi wont turn on, i already did flashing firmware, wipe cache and dalvik cache but still the same thing
yeah same here. I've been researchin and flashin almost a month now and nobody seriously nobody could fix this issue. shame. i hate that it happened suddenly and without a warning.
Happened to me also...This is how I fixed it (accidentally of-course ):-
---First mistakenly dirty flashed stock ROM via odin v 10...That was an honest mistake
---Couldn't start my phone due to it...FC messages were appearing again and again...
---went to download mode...directly flashed CF-Auto Root and TWRP from ODIN again...
1) Wiped everything from TWRP
2) Went to download mode and flashed Stock ROM via Odin.
3) WiFi didn't turn on even in Stock ROM (came as a shock to me)
4) went to download mode...directly flashed CF-Auto Root and TWRP from ODIN again
5) Flashed "Doctors-Amputated-V3" and "CWM-Modem-I9500ZCUJOH2_2" via TWRP.
voila !! WiFi working again in the new ROM :laugh:
Hi mate,
Could you please explain what "Doctors-Amputated-V3" is? A custom ROM?
Basically, I have flashed the stock Samsung image and a previous backup, and still have issues having used PryFi. I'm trying to get my WiFi back to stock and probably flash a kernel or revert to whatever is most compatible, so as to stop my device rebooting...
Could you please recommend a kernel or modem to flash, and then the best kernel or modem to flash afterwards, in order for maximum compatibility. My S4 has always been stock rom, just with Root.
Appreciate your time Prateekgupta!
Cheers,

---Yes its a custom ROM...
---PryFi breaks phone's Wifi every time you use it...I've given up and uninstalled that app....Flash stock rom again through ODIN...
---The process I described didn't solve my problem...My wifi worked only for 20 minutes...After that it went back to grey...
---No software trick can help if your Wifi and Bluetooth both are not working...Its basically the Wifi antenna/IC that needs to be fixed...Its a hardware issue...

[Q] Doesn't boot

Hello,
I've got a problem with my gt-i9505.
I've managed to root the phone and install TWRP.
So i decided to install CM10.2 (21-08) and the right gapps for it.
Everything worked very good and I couldn't be happier.
All my apps were back and it was ready to use it!
I turned off the phone and went to sleep.
The next day i turned it on and it got stuck on the bootscreen (not the CM bootscreen, but the SAMSUNG GALAXY S4 bootscreen).
So I tried to do factory reset and install rom again, gapps again, afterwards again wipe dalvik and cache.
But i keep having the same problem. Right now after flashing the rom it doesn't even boot up the first time.
I also tried going back to 10.1, but same problem.
I don't know what to do, i just got my s4. Really hope i can fix it.
Luckily i can enter the recovery. But i didn't do a backup or anything.
Does anyone have any tips on how to get it working again?

Hi,
Look HERE
Put everything back to stock then, try again.
I found some 10.2 ROMS do not like rebooting,and just hang.
Remove the battery and try again normally worked.

Thanks for replying
I followed the instructions and succesfully installed the official stock rom for my device and region.
But it's still stuck at the samsung boot screen.
And now i can't boot into TWRP anymore either, is that correct?
After that I flashed with the .pit file. But still stuck on bootscreen.
Is there any other way to solve this problem?
idgaf about custom roms or CM10.2 anymore, i just want my phone to work.
Wether it's with custom or with stock firmware.
Really hope I didn't break my phone. :crying:
EDIT:
I wiped cache after flashing, but no data wipe/factory reset. That did the trick.
God i can't be happier my phone finally works again. Now i'm scared to flash a custom rom again. I think i need to install TWRP or CWM again too I'll just wait for now.

help please

Hiya guys need some help
I have a galaxy s4 gt-i9505 that I had running the Google play edition ROM
Then my wife ordered a galaxy gear for my birthday (early January)
I tried to put the latest carrier ROM on through Odin and it flashed OK but kept coming up with procces.android.acore has stopped
I did some googleing and then re-flashed the ROM but clicked the wipe button and it flashed OK
But when it restarted it got stuck in a bootloop and wouldn't get past the Samsung logo
I then flashed twrp recovery and managed to get 4.4 ROM on there (but it seems really laggy and drops calls everytime)
I have tried to recover my backup but twrp can't see it and the cwm recovery won't flash on
So how do I either get stock back on my phone or a ROM that will accept the gear and isn't laggy or buggy
Thanks in advance for the help guys

Download the triangle away app. (search google or xda)
Download the latest Samsung ROM from Sammobile.com
Enter in recovery mode and WIPE all data,
Flash the ROM via ODIN.
When its done, enter in recover again and make another wipe.
If u get a successful boot, and if u have a new bootloader(knox) u wont be able to use WIFI, u'll need to use Triangle away to wipe the binary counter. SO then u will need to REFLASH the ROM.
After all of this, u should get the phone working fine.
Sorry for the text. ;o
IF U DONT HAVE THE NEW BOOTLOADER (KNOX), JUST WIPE THE SYSTEM BEFORE AND AFTER FLASHING.
Good luck, bro.

Correct ROM for ur UK branded to Vodafone is this ONE
ok so i admit i'm an idiot,
what i forgot was that i needed to use adb to get into cwm recovery
when i realised that i could recover back to my stable version
so in order to use the gear (when it arrives) do i need to go back to stock or can i use the google play edition rom i like ???

also have to admit i was freaked out that you knew i was on voda ..... till i realised it was in my profile lol
ok so i did all of the above with the correct firmware and again it just keeps saying acore ?? process stopped ..so i had to flash back through to the 4.4 rom then flash cwm on and restore my old 4.3 rom
i tried a wipe through odin and that just caused a bootloop again
any other ideas on how to get back to stock ??

Mate, try this steps:
1. Flash stock recovery
2. Flash stock rom from sammobile
3. wipe
The gear only works with stock rom 4.3
ok so i tried everything nothing worked and i got stuck in a constant bootloop
then i tried flashing it with odin 3.09 .......all was going well till it failed and left me with nothing on the phone at all
i re-tried with through 3.07 and this time it worked
i now have stock on my phone thankfully
thanks for all the help guys

[Q] Galaxy S4 Sacs Rom Issue Please Help

I just flashed this rom successfully yesterday. The rom was stable and working, however I wanted to get the hotspot to work. I used a hotspot mod on a previous 4.3 rom, so I tried it again on this rom. I flashed the MDC Hotspot Mod while in Philz Touch 5.18 recovery. After flashing the hotspot mod, I reboot the system and it is stuck at the "Kit Kat" splash screen. I went back to recovery, wiped everything (data reset, cache, davlik cache) and reinstalled the rom and it seemed to work fine. However, I wanted to get the hostpot working so later in the night I reinstalled a 4.3 rom, and now I can not get any rom to work. When I boot up I am not faced with the Galaxy S4 screen saying:
KERNEL IS NOT SEANDROID ENFORCING
Set Warranty Bit: kernel
It will not go to the Kit Kat splash screen, I can get to download mode and recovery mode. I tried completely re-rooting the device, Installing different roms and even a different kernel, but I can't seem to get anything to work. At this point, I just need my phone to work and will use any rom. I don't think this is a fully bricked device because I can get into recovery and download mode. I can live without hotspot for now, just need a working phone. If anyone can advise here or help please reply here or email me at [email protected]. This is my daily driver phone and I need it to work, hopefully it is an easy fix like getting a stock 4.4 kernel? BTW this was a brand new galaxy s4 which came with stock 4.4, so I am not sure if installing 4.3 had an issue with it. Maybe using ODIN to fix the problem, I am not sure. I have successfully rooted many phones including HTC EVO 4G, HTC EVO 3D and Galaxy S4( until now) and have never ran into this issue. Please advice anyone!! Thanks!
RE: S4 Sac Rom Issue Please Help
I ran into a similar problem and my device would not boot. I simply just reflashed clockwork 6.0.4 recovery from Odin and was able to get back into recovery to wipe and reflash a new rom. Hope this helps. Note: I selected PDA in Odin. Here is a tutorial to get recovery back.

Boot problems after stock flash

A friend of mine was running CM on her L720 and asked me to re-image it. I'm not sure what version of CM it was but it was definitely a 4.4.2 build. I tried to flash back to stock using Odin and FNG2 img. Odin reported that it passed but the phone won't boot. It displays the Galaxy logo for 5-6 seconds then goes black and nothing else happens. I can boot into download mode and recovery (CWM). I've tried reflashing and factory reset, but no luck. I have not flashed stock recovery back yet...could this be the issue? It seems like a logical next step but since I know little about troubleshooting these issues, I thought I'd better ask before I screw things up further. Any help would be greatly appreciated. TIA!
Nevermind...apparently I did not have the full image somehow. Downloaded from another location and it's working now.
