i337UCUF NB1 wifi problems.

Hi all,

new to posting on xda, but were reading you guys since 2011 / S2.

PROBLEM:

#1: I have a standard problem when wifi does not switch on after reboot. it appears on most roms (except ROM with default NB1 (which is Venomous Droid Blue droid) .

problem#2: Also I noted that I can't unlock(screen unlock) the phone after a some time (12hrs+) on most all roms - phone freezes after i try to unlock it, just black screen with no response from phone(or main menu frozen screen), however it works as people can call me, but phone does not display any signs of activity.

Story:

I got S4 refurbished from Aliexpress. seller advertised it as 9505. It appears (from download mode/ability to odin nb1 roms) that it is i337. Phone initially came with weird firmware I9505ZHUEMK2 (which is Hong Kong version). after couple of days i figured out that twrp would not work and I need safestrap. I decided to odin mk2 stock rom, which failed (wrong binary in download mode screen on the phone or smth). using this code i figured out that I am on nb1 and odin nb1 successfully.

I flashed custom google edition 1.2 4.4.4 rom as per instructions (initially odined back to nb1 stock that worked almost fine, incl wifi/reception; then TRed it, safestrap 3.72, wipe, then rom+Su in SS, then NB1 modules in same SS straight after ROM).

i have following in default recovery: KOT49H.I337UCUFNB1

Problem details:

When phone boots 1st time or couple of times after custom ROM installation everything works perfectly fine, BUT after rebooting wifi disappears (stuck on switching on wifi process). re-flashing just modules/modems helps...

Also after installation some firmwares had wifi working but cellular reception did not work. even with flashing modules in safestrap.

I tried to flash 4.4.2/4.4.4 roms like (all had wifi problem):

Google Edition for SafeStrap v1.2 -- 4.4.4 -- ATT -- 2.24.15

Pure Nexus Edition for SafeStrap -- 4.4.4 -- ATT -- 2.5.15

S4 Google Edition for SafeStrap -- 4.4.4 -- ATT -- 6.28.14

MD v1.2 -- UCUFNJ4 -- ATT -- 2.11.15 (touchwiz) (this one probably had problem with cellular reception, not wifi)

GoldenEye v49.2 -- XXUGNK4 -- ATT -- 1.26.15

Now I am on the following ROM (wifi works fine, but phone sometimes can't be unlocked/black screen with no signs of life while still others can call me, but I can't respond due to black screen/no ringtone):

Venomous Droid Blue Chrome SS Edition v1 -- UCUFNB1 -- ATT -- 4.16.14

which has default NB1 module/modem or whatever it is. Works fine!

But I want google edition/cynogen type rom, without touchwiz/weird customization like in this rom.

Thanks in advance!

Crazy question as I assume you've read the first page of this thread. Have you flashed the appropriate kernal modules after flashing each rom? For NB1 there would be an NB1 module that will make wifi work.

[AT&T Samsung Galaxy S 4 General] trueyakuza:
thanks for responses.

I tried nb1 and nj4 and other modules as well as RockRatt modems. does not help.

now I took stock NJ4 update, and flashed google play edition 4.4.4 v1.2. tried standard nj4 modules and rockratt modems. Same thing. Phone looses wifi after standart reboot.

However I found a walkaround:

I do hot reboot after standard boot/reboot, which brings wifi back.

after sometime wifi disappears again and hot reboot does not help, so I take standard reboot, and then hot boot.

any thoughts?

have not tried lollipop yet, as I honestly does not want any TW or samsung stuff..

[AT&T Samsung Galaxy S 4 General] t4duzan:
I forgot that you were flashing a GPE rom. I believe that is indeed what it takes to get the wifi working...the hot reboot. Also you'll be missing a direct wired PC connection when you are plugged in. You'll have to use wireless apps if you want to connect to the PC. I've not been flashing like I was last year so the threads have gone dry for me and there very well might be fixes for what I listed, but I don't think so.

I'm about to leave AT&T

I wanted to reach out to any who read this thread and get your opinion on Sprint? I have 3 contracts up by the first of May and to re-up with 3 new phones is a lot more than it was 2 years ago. Sprint will cut my bill in half and I could finance the 3 phones for $70 a month, for about what I pay now for my bill. Has anyone had any good or bad experience with Sprint? I know they update software quicker than AT&T so that would be a bonus also. Let me hear from ya.

Thanks in advance. ..

Edit: I forgot to mention that I've been with AT&T for over 12 years and have never frequented any other XDA forum. Hopefully they make magic as well as the AT&T side over here.

So I've successfully flashed Albe Lollipop and Golden Eye Lollipop to my i337 on OC3 with a few work around. Although I could not get the menu button remap add-on to work with Albe. I also failed at getting the GPE rom to boot. All I would get was a black screen. Those are the only roms I could think of using

Please, share with us your workarounds to install Albe95 LolliROM Official 3.1 on AT&T's OC3.

Thanks
[AT&T Samsung Galaxy S 4 General] eagleflyfree92:
Custom Roms on OC3!

1. Use the OC3 keep root method by [MENTION=4708661]muniz_ri[/MENTION] found here.

2. Of course, download the Rom and SuperSU to your device.

3. Install Safestrap 3.75 and install the recovery.

4. Download the OC3 Modules found here (Pulled by [MENTION=4802557]Apoplectic1[/MENTION]) and place it on your device.

5. Download the NC1 flasher app and the OC3 kernel from here by [MENTION=5300329]K-alz[/MENTION] and place them on your device.

6. Open NC1 flasher, read the warning, and then FLASH. Press reboot.

7. The phone will boot directly into Safestrap. Do everything like you normally would: Wipe, Flash rom, Flash OC3 modules, Flash SuperSU, then last, flash the OC3 kernel downloaded on the same page as NC1 Flasher.

If everything went ok, your phone will boot up. The Safestrap screen will pop up maybe 4 times, I think. Just keep hitting continue. Then after that the rom should boot.

If you have any problems you can Odin the NC1 kernel back to your device and get back into Safestrap.

As I said I only tested with Golden Eye, Albe, and GPE (which did NOT work) Lollipop roms.

All Thanks to:

Edit: Also don't flash any custom rom via FlashFire.

I found out the hard way and tripped Knox! Oops!

Anyways I hope all works out with this work around.

Do not forgot to either flash the OC3 kernel or Odin the kernel after flashing or you will have problem!

Nope. Nobody.

[AT&T Samsung Galaxy S 4 General] Guedeaux:
This worked for me going from OC3 stock rooted to Goldeneye V52.

Also, I think you can uninstall safestrap recovery after flashing to improve boot time (you can reinstall prior to running NC1 flasher as needed.
[AT&T Samsung Galaxy S 4 General] eagleflyfree92:
Yes you are correct I forgot to mention uninstalling safestrap. I'm glad it worked for you!

[AT&T Samsung Galaxy S 4 General] nickhaven:
In a nutshell yes. Odin to stock mk2, get root, get safestrap, flash nj4 (stock w/ root) in safestrap, odin the nj4 kernal, then you can install safestrap, and flash you desired nj4 ROM.
[AT&T Samsung Galaxy S 4 General] guut13:
No. Odin to NB1 stock and then take the OTA which will put you on NJ4.

If you have already Odin'd to NB1, you cannot go back to MK2.

If you are going to stay on NB1 base... sure. It will make life easier for you.

If you are going to upgrade to NC1, NI1, or NJ4, then you might as well flash the regular one.

KK 4.4.2 ROM flashing in rooted MK2 AT&T i337

Hello,

Probably have missed something in explanations and tons of info in i337 threads, and as a result I do something wrong. But I'm not sure where am I wrong. Please help to understand:

I try to flash a KK 4.4.2 custom ROM (several of those) out of Android Development threads here. Each time I do this it ends up in a bootloop, but ROM does not start up.

I have the Safestrap Recovery V3.71, and as I mentioned the phone was AT&T i337 MK2 rooted. I flash the ROM in a non-stock partition.

So, what wrong with the process? Is it possible at all, or I just do what cannot be done, and why is that?

What shoud I do to allow KK 4.4.2 ROM installation in this device? Should I update stock ROM, and what about having it rooted after that?

Thanks in advance!
[AT&T Samsung Galaxy S 4 General] rebel1699:
You cannot flash a 4.4.2 rom with safestrap 3.71, as it is intended for 4.3 roms. The 4.3 kernel is not compatible with 4.4 KK. There is no safestrap for 4.4 until after kk is officially released, if the dev, hashcode, chooses to do so.

How do I switch ROMs?

I have flashed the Google Edition S4/ Pure Nexus Edition[SAFESTRAP] ROM by Joe-tech, works great and I am able to use SuperSU and no matter what root checker I grab from the play store they always tell me yes my phone is rooted, however a lot of apps that need root, don't seem to work at all.

For example, I used to use an app by Killer mobile to record calls, this does not work anymore after I switched to this ROM. Also tried to use snapprefs for Snapchat through xposed, doesn't work. I want to try a different ROM, but I have no idea what I am doing and hand to get someone to hold my hand when I first flashed the google ROM. Would I just download the necessary files and flash through safestrap? Or do I need to do anything first besides a data backup?

Also can anyone recommend a ROM? I just care about battery life and don't want any unecessary apps.

Thank you.
[AT&T Samsung Galaxy S 4 General] t4duzan:
He might have meant to flash the supersu zip after the kernel, but I might be wrong here. I think the supersu zip would be the last thing you do.

---------- Post added at 12:16 PM ---------- Previous post was at 11:57 AM ----------

There are tons of safestrap compatible roms on the OP of this thread so I would take any of those for a spin. As far as how to switch roms, it always happens in safestrap. Just like how you initially flashed the rom you're on now is how you would flash your next rom. The only difference is your would wipe all except your SD card and then flash away. I would spend an hour or two and read the first page and some of the links it points to.

Something I've experienced with my current rom (Imperium, linked on the first page) is Supersu won't always work right when granting root permissions so inside of the SuperSU app, I changed it to always Grant permission when asked. Not the best solution, but it's a work around.

I see some have had success using Albe95's roms (I see [MENTION=2982241]guut13[/MENTION] has 2 linked to the OP) but wanted to reach out and see how everyone likes them? Seeing how it's a new OS to my current KitKat, I'm hesitant to jump in as a normal rom and try myself so I wanted to see if anyone has experienced problems. I do see that I'll have to flash SuperSU after flashing the rom and module, but other than that, how does everyone like it?

Not sure. I had a similar issue when I flashed GoldenEye, I even tried flashing the UPDATE-SuperSU-v2.46.zip right after the module.

I had to use the S4 for as a phone for a change so I was going to live without root for the day I needed it. After all that, I went back with Odin and flashed the NC1 kernel, and was about to wipe the phone but I thought I would give the UPDATE-SuperSU-v2.46.zip one more shot and that was when I got root. Not sure if the story of my journey to root on GoldenEye helps but I thought I would give you all the facts.

Just a side note I did open the SuperSU app and tell it to "allow root on boot" and "Allow all" instead of "prompt", just to see if that would help, and that was before I flashed SuperSU again.
