Flashed custom recovery, WiFi broken

I have an SGH-I337 with Android version 4.4. I have the Knox bootloader (sadface). I attempted to root this phone previously using Saferoot but this caused problems (relevant thread).
I can connect to the data network but I can't get the wifi to work. It won't even turn on. As soon as I tap the switch it goes back off.
Please help.

You'll probably have to use the NB1 full ODIN to fix it. Make sure to back up your internal storage and anything that doesn't sync to your Google or Samsung account.

Ok, I'll try that.
While I have your attention, I have a couple other questions...
- Do you know if this phone is actively being worked on by developers? As in, are exploits being researched to unlock the bootloader?
- Can the phone be rooted with an update? What is the preferred method to do this? Recovery (I have teamwin) or ADB?
EDIT: Is it safe to flash just the modem or would you recommend the full phone firmware. I found a thread here with firmware.

The phone is actively being worked on, most progress is kept between PM's or in a thread in the Verizon S4 section (they're in the same boat as us and chances are an exploit for one will work on both).
The phone can not be rooted with an update because we can't sign it once we add the su binary.
You can't flash the modem as those are recovery flashable zips and if you're on NB1 you can't get root or recovery without a more involved method first (no simple one click).

Thanks much for verifying that for me. I'm content to wait until a solution is found. Just relieved to hear that the smarties are still tinkering with it. :good:
I guess I don't have TeamWin then? That's odd because after my failed root attempt, it was after I tried flashing teamwin that the phone booted back on after being softbricked. I guess that was coincidence then. At any rate, I will try to flash the NB1 firmware to fix the wifi. At least I have data. :silly:

WiFi issues with OTA firmware too
Just thought I'd add that the OFW has WiFi issues as well, at least for a few if us. When I updated OTA to 4.4 the WiFi worked for a couple of weeks then stopped working (reboot will allow it to work for a while until the unit sleeps, then it won't toggle). I tried the Odin tar.md5 image and the same thing crops up. This thread is relevant: [Q] OFW 4.4.2 WiFi Not Turning On. I like KitKat, hopefully we can figure out what the problem is.

You likely overwrote the stock recovery. Here is the NB! stock recovery. Flash in PDA slot in Odin:https://mega.co.nz/#!M9EQBT5A!ri4QeMYpgi-JjmUGZ3FY2gtogDBWPEL7zRCjASIcVe8
If you need the NB1 stock modem here it is. Also flash in PDA slot in odin: https://mega.co.nz/#!sstkFRiJ!d9zTRte0KcVFv7o-bjKFuFMM1Q9ivzDlqJKy2OlP_7o

I haven't gotten around to trying it. The phone is working now so I'm a bit reluctant to do anything to it until future developments bear fruit.

[Q] Samsung Galaxy S4 AT&T root for I337UCUGOC3

I'm looking to root my s4, I just upgraded to lollipop and love it but there are some things I would like to do that require root. Hoping that someone can walk me through the process. Thanks in advance

Interested in this as well. Just need a point in the right direction. Thanks

I may be incorrect, but at the moment root for I337UCUGOC3 is only available via Flashfire.

So there is no straight root from 5.0.1 at the moment?

No. You have to downgrade to 4.4.2 first, root, then flash up to 5.0

Bumping an older thread.
I've been searching around the forums for a guide to downgrade and a link to the Stock 4.4.2 ROM. AT&T Upgrade happened inadvertently. I either wasn't paying attention or it happened automatically.
Found plenty of post saying the same thing but no trustworthy guide on how to downgrade effectively from 5.0.1 on the i337 to 4.4.2. Normally I'd be up for experimenting but a newborn has me a little sleep deprived and looking for an idiot guide.

Are you trying to get back to 4.4.2 then attempt to upgrade too 5.0.1 root?

Yes, but it sounds like from the tone of that question that I might be screwed.

You can flash back to nb1, root with towelroot, and go to lollipop with the keeproot method. Look in the general forum for [GUIDE]Odin to Stock, Updating, Rooting, and Installing Safestrap by guut13 and [How-To] Update to I337_OC3 - 5.0.1 and KeepRoot (4/7/2015) by muniz_ri.

I also have a I337UCUGOC3 running 5.0.1.
Unfortunately yesterday my phone got messed up (I'll spare you all the details) and I had to do a factory reset. I am really unhappy about this because I wasn't able to backup properly with Titanium Backup since I'm not rooted. As a result, I now need to spend a bunch of hours getting my phone back to the way I like it. I am honestly not interested in flashing custom ROMs. I simply want to root so I can run Titanium Backup.
Based on your experience, how long might it typically take for a root guide to come out for this model? I'm trying to decide whether I should try to wait it out with my phone feeling "unfamiliar" to me - or if I should just go ahead and give up the idea of rooting / backing up.
Also, is there one site or forum (this thread???) where I would be able to find out how to root this model when it comes out? If so, where?
I would very much appreciate your advice!

There is no way to root on OC3 at the moment. No clue on how long it'll take if a method even gets found. I recommend downgrading to NB1 using Odin then following the steps on herehttp://forum.xda-developers.com/showthread.php?t=3075814

FWIW my wife noted the user interface on her S4 suddenly completely changed. Looking at it when I got a chance I saw it was 5.0.1 (OC3). I actually don't know what it was previously. So AT&T is definitely pushing out the update.

Already on 5.0.1
I bought this ATT phone used, unlocked, and already on 5.0.1. We use it on the GoSmart Mobile network (owned/operated by T-Mobile). Today (a few weeks after the purchase), I get this message saying that there's an ATT software update available. How can ATT push an update to a phone not on their network? Will this update screw anything up? Will it re-network-lock it? I don't want to update this phone and, since it's my wife's phone, I don't want to risk a brick (I am in a similar situation with a baby and am quite sleep deprived). Previously, she had an HTC First (ATT phone use on GoSmart) and it notified us of an available update, but would not actually update (thank goodness). Do I actually have anything to worry about with this ATT update? Or is the notification just an annoyance? Thanks in advance.

The latest update, from 5.0.1, OC3 to 5.0.1 OC4 is a security update which is believed to be a response to the stagefreight bug. The update is relatively small, and should not "screw anything up." It will not affect network unlock.
As to why you're getting it on a non AT&T network, I'd guess that the update server determines the phone is an SGH-I337 and pushes the correct update for the phone.

How to root
Okay, so I have 5.0.1 with i337ucugoc3 and finally rooted it quite easily (after many failures).
I used WonderShare's MobileGo.
The process was actually very simple, but it was very confusing as to what the software actually wanted from me.
To make it easy, here's all you need:
1. Go to Settings->more->About Device
2. Tap on "Build number" seven (or more) times quicly
-- this will unlock the developer tools
3. Tap the back arrow
4. Tap "Developer options"
5. Tap on "USB debugging" to enable
6. Go to wondershare.com, download MobileGo, install
7. Run MobileGo
8. Connect your phone to your computer with a USB cable.
9. In MobileGo, click on the "One-Clock Root" button
You should be rooted quickly.
Not only that, it only installs SuperSU, and no malware.
10. Uninstall MobileGo if you don't want to keep it.

Would this work also for i337ucugoc4?
When you say "after many failures" - were there ever any negative consequences (something broken or bricking, etc.) from one of those failures - or just not getting root?

I don't know, but supposedly it works very well with most versions.
None of my failed attempts left any bad effects, this program worked first shot :good:

Does the phone get wiped in the process - or does everything stay intact / in place?

The Wondershare MobileGo One-Click Root process successfully rooted my unlocked GS4 i337 (OC4) today, and confirmed by Root Checker. So easy!

You wrote you want to reset your phone to the BS free ROM, but then at the end you write you want to get root access. What state was your phone in when you started to try this? Was your phone already rooted? Was your phone already rooted and on BS free ROM and just needed to clean up your phone and get back onto the BS free ROM? If you were not already rooted and had taken the Verizon OTA updates to Lollipop, chances are good you cannot root your phone, and therefore you cannot run the BS Free ROM. Let us know what state your phone was in when you started this so we can help you better.

What software version you're on and did you have root before you tried to reset to Verizon Galaxy S5 to BS_FREE_Lolipop??

To reply to everyone the only thing I ever did with the phone was update to 5.0 If I can't get root no big deal but I really want to install something that gets rid of all the Verizon junk apps :/

If you never rooted your phone and you took all of the Verizon OTA updates to 5.0 you are most likely on OG5 and cannot root your phone. If you took an OTA update in the past few days before trying this, you may have been on the latest OK3 security patch update. Your best bet would probably be to find the OG5 full factory tar file and flash it in ODIN to get your phone back to a working state. I think there is a thread in the general section where you can find the file you need.

Sorry to keep saying no, but if you are on OE1, OG5, or the new OK3 you cannot downgrade. You are stuck where you are.

SM-G900V on 442 - want to upgrade without losing root

Hi. Couple years back, I used Towelroot to mindlessly root my SM-G900V on version 4.4.2 (no CWM, stock bootloader, locked, thanks Verizon!). Google Now crashes the minute I open it and I figure it's time to update from 4.4.2 to 5 or whatever is stable these days. I'm paranoid to do this without running it by you gurus here, because I don't want to lose root, brick my phone, or turn it into a flaming fireball of doom. Can someone point me to a thread I overlooked or just type a few easy-to-follow steps with link to ROM so I can upgrade my Galaxy S5?
Is a downgrade back to 4.4.2 possible if I don't like the upgrade?
Thanks in advance!

Thanks. I've spent a couple of hours and am on post 171 of the thread. I'm a CID 11 that needs to follow those steps on post 3. Regardless, this seems to be designed to take me from Kitkat to Marshmallow, skipping me right past the land of Lollipop. I haven't tried it yet, but 2 questions:
1) once in Marshmallow, can I get back to Lollipop or Kitkat?
2) the intro to the steps say that CID=11 needs SafeStrap or Flashfire, but the actual steps never mention Flashfire (only safestrap). Is it truly either/or, or is there an advantage to SS?
Thanks!

1. Lollipop - yes, Kitkat - no.
2. You still can use SS on MM. It's a little tricky but still possible.
Flashfire requires root so it will not work on MM for CID 11.
This thread may also be useful for understanding the things: https://forum.xda-developers.com/ve...al/guide-painiacs-essential-guide-to-t3319848

I'll check out that thread (thank you for that), but I'm confused by something you wrote: "Flashfire requires root so it will not work on MM for CID 11." My Kitkat currently has root. Are you suggesting that when I throw Marshmallow on it I'll lose it?
And if you all will allow me to hijack my own thread, is Marshmallow really worth the upgrade from Lollipop? Heck, is Lollipop that much better than Kitkat? I've got a (mostly) working rooted system now, and it sounds like I can go up to 6 and back down to 5, but never again back to 4, hopefully keeping root the whole journey.
Thanks for reading and helping a new guy out. I figure others will find this information helpful down the road, as 4.4.2 was easy to root.... but where (if anywhere) from here?

Yes.
You say your phone has CID11. For SM-G900V it means it has a locked bootloader that cannot be unlocked (currently, but most likely - never).
Locked bootloader is called so because it's locked to boot only certain digitally signed kernel (aka boot.img)
Root on MM requires a modified kernel which cannot be booted by a locked bootloader.
That's why you cannot have root on MM and will lose it when upgrading.

Only you can answer for yourself.
What are you using root for?
I have 4 or 5 S5s (G900V) here running MM and only one (mine) is rooted. No claims so far They just work.
BTW, all of them are running Devbase-4.2 from Alexndr.
If you're on Verizon you may like one of stock debloated ROMs which can be found in this section.

Thanks for all your help.
Reading the first few posts here really helped a lot to get a background. Then I attempted the steps here you provided on post 3 for my 11.
I thought I could pick my build after reading painiac's post, and was shy about going all the way up to PB1, but all the ones I chose wouldn't TowelRoot. I really did have to follow the instructions as written and use the COMBINATION EMMC ROM provided there. It freaked me out at first that it ended me up in Kitkat, but the final step brought up Lollipop and completed the process well.
The one scary point is after I ran Titanium getting ready to put some apps back on and used the "restore previous ID" it gave a panic, took me back to recovery and froze... required removing the battery, where normally that just causes a reboot. I did read the part in Painiac's post where he says don't restore system app (I had to export and import my contacts using the phone app to SD card and not Titanium - that worked). I hope my "restore previous ID" didn't go against his advice.
Other than that, things seem to be working smoothly now. I'm on Lollipop PB1 and not sure I even need Marshmallow. Thanks for all your help.

A couple of months back, I updated from Kitkat to Lollipop using the instructions below, and ever since, I've had two persistent problems, and I'm wondering if anyone else has:
1) Wi-fi cuts out every few days requiring a reboot fix. This seems to be related to DNS.
2) Receiving picture texts (MMS) show up as "Message size: 2KB Expires: (date)" with no way to download or view. I see no workaround other to tell friends to email me pictures instead of texting them.
I've tried a factory reset, but haven't gone back to Odin yet to try to put PB1 on again (or a different ROM?). The good news is SafeStrap recovery is on the phone now. What can I try next to resolve these two problems? I can live with them with the reboot and avoiding MMS, but they are not trivial.
Thanks for any guidance or advice. Please help.

I really did have to follow the instructions as written and use the COMBINATION EMMC ROM provided there. It freaked me out at first that it ended me up in Kitkat, but the final step brought up Lollipop and completed the process well.
The one scary point is after I ran Titanium getting ready to put some apps back on and used the "restore previous ID" it gave a panic, took me back to recovery and froze... required removing the battery, where normally that just causes a reboot. I did read the part in Painiac's post where he says don't restore system app (I had to export and import my contacts using the phone app to SD card and not Titanium - that worked). I hope my "restore previous ID" didn't go against his advice.
Other than that, things seem to be working smoothly now. I'm on Lollipop PB1 and not sure I even need Marshmallow. Thanks for all your help.

Shortcut to being rooted on N910VVRU2CQI2

Here's my Cheat Sheet ! This is the same procedure I used a while back with N910VVRU2CPD1 . I just updated the thread to work with the newer package.
1. Odin SamMobile N910VVRU2BPA1
reboot and factory reset a few times if needed to remove custom icon
2. Odin hsbadr's N910VVRU2BPA1_N910VVRU2CPD1_FullFirmware.tar HERE
3. Unlock with the samsung_unlock_n4-fix PROCESS use SIM card for data. Wi-Fi will not work at this point.
4. Odin twrp-3.0.2-0-trltevzw.tar Uncheck Auto Reboot, Manually boot into TWRP
5. Odin hsbadr's N910VVRU2CPD1_StockRestore.tar HERE
6. TWRP BETA-SuperSU-v2.71-20160331103524, Factory Reset, boot system
7. Use FlashFire to Flash firmware package SamMobile N910VVRU2CQI2
( ! System and Cache only ! )
Your mileage may vary.
Before I install my personal apps I remove as much Verizon, Samsung and Google spyware as possible.
-------------------------------------------------------------------------------------------------
EDIT: I was able to skip the recommended rooting and unlocking of 5.1.1 and make the jump I described.
I did not do the unlock using Kingroot until step 3 and I did not permanent root with Super Su until step 6.
No matter how you get there the phone has to be on [Firmware] [MM] [6.0.1] [RetEd/DevEd] Safe Upgrade to Marshmallow [N910VVRU2CPD1] then you can use FlashFire.
Hyperlinks are in the text to most of what's needed.

I keep seeing people saying there is a way to just flash TWRP and Magisk and you're done. I'd like to avoid SuperSU and the other root methods if possible. How would that work with your updated guide? Thanks

My main concern is the spyware the guys on Reddit bring up. Not to use kingroot and the like. Was there any resolution to this thread you posted Dr cool? Want to unlock my bootloader and flash the MODest ROM but I want to be able to avoid spyware too. Thanks for your work.

I'm not sure if it was spyware or what. but my phone performance better after cleaning out that folder.

Thanks doc. Is that a folder that gets overwritten when you flash a new room?

This says "Continue with sim card data because wifi wont work at this point."
What if we don't have any data right now? Will it still work?

Kingroot needs to connected to root. I never seen it work without a connection. N910VVRU2BPA1_N910VVRU2CPD1_FullFirmware.tar brakes wifi but you get it back with N910VVRU2CPD1_StockRestore.tar, I dont know why. It just works

My best guess now is it's some kind of provisioning issue that is cleaned up. Some of the files deleted you may actually need some day.

does this require the developer version? btw how do i backup

I seem to lose root after I flash CPD1. Still have TWRP though and says developer mode. What could be causing this?
Edit - When I flash stock restore I mean. I get rooted on BPA/CPD and then when I go to the next step I'm losing root and Kingroot says it has no solutions. I must be doing something wrong.

As long as you have TWRP installed still you are in good shape. At that point, you could either flash (through TWRP) SuperSu or magisk (on certain kernels magisk install errors out in twrp). The main objective is to get the custom recovery (twrp) installed on the 6.0.1 bootloader and once that's done it's just a matter of flashing your preferred rooting method or flashing a rom that has root included.
You can use an app like this to check your bootloader to make sure it's the right one.

That's weird. I flashed SuperSU but it didn't show up in the apps and when I tried to use Flashfire it said I didn't have root.

Got there. SuperSU had an error message when I tried to install it the 1st time after flashing full system. So I rebooted and installed again. Now Flashfire crashes and won't open. Switched to Flashify and it seems to work ok.
Edit - Stuck here for now. Flashify can't seem to find the CQI2 file and I still haven't been able to get Flashfire to work. Tried an older version and still crashes when it checks to see if I have the pro version or not.

In case someone else has the same problem with Flashfire, it's because the program expired April 1st, 2018. Turn the date back on your phone and it will load.

Finally completed it!!!
Ok, so the things I learned from my trials and errors.
1) DON'T flash the kernal and SU after you root with the N4 fix. I did this the 1st 15 times and could never get Flashfire to work later on. So skip all of the stuff in that post after you flash TWRP. Then flash the next firmware step.
2) Uncheck auto time and date on your phone and roll it back to before 4/1/18 to get Flashfire to work.
I'm sure there are some more things and I'll add whatever else I think can help the next guy along. Good luck! And thanks for the guide doc!
Note: Did the phone icon on your lock screen disappear as well when you were done? The camera is there on the bottom right like normal, but the phone is gone on the bottom left and it displays the charging info there now.

Thanks for this - it was helpful to make clear that in my mind that despite what other guides say, there is no need to unlock a Lollipop bootloader with a Lollipop kernel + ROM first, and that we can boot a Lollipop kernel + ROM with a Marshmallow bootchain and unlock the Marshmallow bootloader from the get-go.
I tracked down the CQI2 full Odin and I made hybrid Odins that get you "rooted on N910VVRU2CQI2" in fewer steps, following hsbadr's file naming scheme:
N910VVRU2BPA1_N910VVRU2CQI2_FullFirmware.tar.md5: MM CQI2 bootchain/firmware/modem, LL BPA1 ROM/kernel/recovery
N910VVRU2CQI2_StockRestore.tar: MM CQI2 ROM/kernel (no recovery - TWRP isn't overwritten)
These should be fine as drop-in replacements for the files mentioned in steps 2 and 5 of your guide.
Using these obviously means that you are unlocking the CQI2 aboot instead of the CPD1 aboot in step 3 while temprooted, and - importantly - step 7 is unnecessary to get to a CQI2 ROM, which is good because Flashfire is now expired :3
I doubt there's much of a real benefit to being on the newer aboot, but hey, why not.

Hey, no one answered my question from a while ago. So I'll ask again, does this require the developer version of the Note 4?

No, this will work with both versions of the verizon note 4.

Ok, thank you very much. I'll try and root my phone with this tutorial now.

Please help!!!!
I followed this link because its supposed to be a way to downgrade from 6.1.0 to 5.1.1 so I can unlock boot loader. However, these instructions make no sense to me. Can someone PLEASE help me. I've been searching and searching for a way to root my note 4 (N910VVRS2CQA1) and can't seem to find a way. I've never done this before so I'm pretty clueless. When I read these instructions, I just don't understand what I'm supposed to be doing. A lot of this tech lingo means nothing to me unfortunately. I'm starting to thing I should just give up the idea of rooting this Note 4 that's getting slower and slower and just get a new one. I don't really want to though bc I love the fact that you can replace the battery. It'd be much easier to just root and upgrade.....well, easier if I actually knew how.
