Phone takes AGES to boot and WiFi doesn't work. - Galaxy S 4 Q&A, Help & Troubleshooting

Hello,
My Samsung Galaxy S4 I9505 takes ages to boot and does not turn WiFi on at all. And when I say it takes ages to boot I mean it takes ages for the phone to get past the initial samsung galaxy s4 i9505 screen.
I have tried a factory reset but no luck.
The problem has come from flashing backwards to firmware that is easier to root (due to Knox). I am using TWRP to try and restore the firmware to a working order, but I'm not having much luck.
Any suggestions are greatly appreciated.
Thanks!

[Q] Help! Rooted Samsung GT-9505 stuck on samsung logo

Hi!
I just rooted my Samsung GT-I9505 a few weeks ago with Odin v3.07 and CF-Auto-Root-jflte-jfltexx-gti9505.tar.md5.
Note that I didn't install any custom ROM.
It worked fine until now.
When I turned my phone off, it got stuck in reboot. The screen is black with a "Android OS is upgrading.. Opening all applications."
It's been 30mins and it just stayed there so I decided to take the battery off, put it back in and turn myphone on.
Now it's just stuck with the samsung logo. And whenever I factory reset and reset cache it, it just get stuck with a black screen with a "Android OS is upgrading.. Opening all applications."
Did I just bricked my phone? Is there any way to fix this?
Any help would be deeply appreciated. Thanks!
Wrong section maybe?

From your post I see you got gt-i9505 and that is plain Galaxy S4, not Galaxy S4 Active (gt-i9295). Although the phones are quite like twins, try S4 forum instead.
But if you really have S4 Active (again, it's gt-i9295, it has 3 physical buttons insted of just Home under the screen) and you flashed 9505 as root method, this forum deals with your approach and this particular post might be of interest. There is however even easier way and that is to root from now working CWM recovery for i9295.
Either way good luck with your phone :fingers-crossed:

Yeah! Sorry. Posted it in the wrong section. Just don't know how I'll delete this post.
Aww.. Thanks! Hopefully it'll be fix before the morrow.
Please pay attention to the device forum in which you seek help
There are many models of S4 and use of some software will turn your device into a $700 paperweight

[Q] Soft-bricked SM-T230NU (what next)....

Its been a few months since Ive bothered trying to figure out how to fix my Galaxy Tab 4, SM-T230NU, but Im finally getting around to fixing it. It sat in my closet for a few months simply because I did not have the time to fix it. It's soft bricked (loads the Samsung Galaxy Tab 4 bootscreen, but stays stuck on the single Samsung logo). Its not hard bricked as power turns on, but it is soft-bricked. Will running NE2 I found in the firmware section fix the soft-brick? I just downloaded odin 3.09, and right now NE2 is downloading through Mega.nz......any help would be appreciated....

Flash the right firmware for your device and see if it boots. If it doesn't boot within 20minutes after flashing, simply reboot into recovery and factory reset.
-DUHA
When I rooted the device, gaining root on the 230NU was abit of work, so I had to go through a lot of in and out holes just to root the sucker, and then a week or two later there are many different ROMs available for the 230NU...I'm shocked that someone finally found a workaround for the marvel processor in the 230NU because the 8 I believe has a snapdragon and/or euronoyx (however you spell it)

[Q] Galaxy s4 bricked after OTA failed update

Hello XDA community
Iam a longtime lurker here what a great community with a wealth of information.
I have a a grasp of the basic rooting and flashing custom roms/kernels over the past few years on my old galaxy s3.
My partner had an OTA update for her gt9505 galaxy s4 today whicg seemed to hang while updating, unfortunately she pulled the battery mid update
The phone can enter download odin mode but i cant get it to open the recovery. I have flashed (using odin) a few different compatible roms they finish installing via odin but when the phone restarts it just turns off it will not go past the galaxy white and black screen. It will turn off again.
It has never been rooted, i spent many hours trying to get to the OS but it fails when restarting. I decided to flash CF-Auto root hoping to get access to recovery. Again it successfully installs cf auto root and restarts and then turns off.
It seems everything i flash never ever saves to memory.
What else can i try please? iam happy installing a custom rom but i cant get it working. iam afraid its bricked for good without expensive repairs.
thanks
lol i managed to get it working.
It was a combination of dead battery and multiple problem cables not charging the phone.

Galaxy On5 sm-s550t stuck at frp

So I've searched around the past few hours and can't seem to find a solution to my issue. I have a friend that is currently down on his luck and staying at a homeless shelter, he bought this phone because phones are pretty much a necessity nowadays, samsung galaxy on5, trouble is that the phone was locked when he turned it on so he was stuck with a paperweight, it's been a long time since I tinkered with phones but I figured I could help him out by booting into recovery and doing a factory reset. I had no idea about samsung factory reset protection and now were back to paperweight mode. I downloaded jodin3 and heimdall, but it never shows as connected. Can I root the phone while in recovery or load the factory rom so I can get the phone working again? Thanks for any help.
No, the only options are either ordering a remote unlocking service or find a guide on YouTube. The YouTube way will involve some patience and trial and error. Many guides don't specify what update on the phone they are working on and/or will state that their particular method works for EVERY phone. The stock recovery will tell you what update that it is on by the build number. This might help pinpoint which method to work.
FRP = Google Factory Reset Protection
Samsung Reactivation Lock is a different beast.
Which one does the phone have?

Samsung S5 (SM-G900F) Stock Flash caused Samsung logo screen bootloop help/advice

Hi ladies/gents,
I've just flashed my Samsung S5 (SM-G900F) with the latest UK BTU stock firmware from sammobile.com for my unlocked device (I've used SIM cards in the device in 3 different countries fine).
I reset the device into Boot mode, cleared the cache and factory reset, then boot the phone into download mode.
Using Odin I flashed the .tar.md5 file under the "AP" section of Odin with auto-reboot & F.Reset Time checked , the process was a success (according to Odin), and then when the phone restart: nothing but being stuck on the Samsung S5 boot flashing boot screen.
I've tried clearing the cache and factory resetting again, as well as installing the AP file again, to no joy.
I'm pretty dumbfounded by this as it seems this is the most straight forward and "safe" flashing to do on the device, yet now I seem to have bricked the phone in doing so.
Most of the advice I can find on the internet to fix the boot loop issue suggests doing the exact process I have just ran through, so I'm pretty close to calling it quits and looking at another brand of smartphone.
If anyone has any advice on how I can try and recovery the use of my phone, I'd be most grateful.
Thanks.
Okay guys/gals in the time it took me to feel sorry for myself and get desperate enough to create a post here the phone seems to have just turned on and working fine
I did restart the phone a bunch of times, but it seems just leaving it 20-30+ minutes does the trick.
Patience is a virtue!
Hi
I am having exactly the same issue with a G900I - tried everything!
Any advice??
