[Completed] Sgh-i337 no wifi? - XDA Assist

Hello. A year ago I bought an unlocked SGH-I337 which is the Galaxy S4, ATT unlocked. When I first got it, it had this Samsung Custom boot and it also was manufactured refurbished. After using it, I rooted it using towel root. I was on Kit Kat 4.4.2 and I saw a post where you have to first something through odin to let towelroot work. I rooted it, wifi worked fine after I put the kernel on. Now I tried to install CWM (I think) and I tried installing a rom which said it was to work with my phone. I wiped cache and everything. And it went through and nothing changed. I was back to my normal phone, with root but the wifi button is not working. Before I flashed the kernel it would go to green and get stuck, now after I tried to install a rom, the wifi wont turn on at all as in the button flicks back to the off position. I have the SGH-I337, unlocked att, I unrooted it, I reset it, nothing changed (ie. batter out, calling *#0010* and something like that). This is in the UCUFNi1 running 4.4.2. PLease help me! Thanks.

Hello,
Welcome to XDA.
If you installed CWM and then flashed a custom ROM with CWM did you do the wipes after flashing the ROM?
If you don't know what that is just boot to recovery, in CWM choose the "wipe data/factory reset", confirm the choice and let it wipe, then choose the " wipe cache" option, confirm the wipe and let it wipe, then choose the "advanced" option, in the advanced menu choose "wipe dalvik cache", confirm the wipe, let it wipe, after that go back to main menu and select the reboot to system option and let your phone reboot and set it all up again then see if WiFi works. Backup any apps and their app data that you want to keep before factory resting in recovery, it deletes your user installed apps and leaves only system apps, your pics and other stuff on internal will be safe, you won't need to back those up anywhere, only the apps and app data get wiped with factory reset in CWM. When it reboots install the backed apps and their data and you'll be back where you are.

[Q] wipe data on rooted and rom'd 3g xoom?

I am selling my 3g xoom rooted and rom'd with EOS 2.0. I need to wipe my data and keep the rom. I think I do this in cwm? Please advise.
1. take out your flash drive
2. delete all your userdata under /mnt/sdcard
3. press power button, select Reboot -> Recovery
device now reboots in recovery mode
4. select wipe data/factory reset
thats all.
I didn't get this msg in time. I ended up rerooting and that finally worked. However, when I tried to just use the wipe data/factory reseting cwm, I received the following error msgs. Posse see attatched photo. I sure would like to know what it means.

[Q] Can't get rid of encryption

I'm really stuck and need some help here, thanks in advance. So basically about a month ago I encrypted my rocket to use on my company's Exchange, but it turns out they don't support Android so that was a waste. At the time I was running Stock ROM ICS (Rogers), before then I had dabbled with Paranoid and a few others. I had CWD 5.5 installed.
Yesterday I was eager to try the new 4.1.2 JB leak, so I flashed it through CWD and all went well.. until it booted. It stops me just as it loads and gives me the message "Enter encryption key to unlock storage". It's been a while so I couldn't remember my PW, so I tried 100x until it said wiping data. I figured maybe it worked the same way as Blackberry, but even still after wiping it wanted the password and now when I enter anything in, it just reboots the phone.
Getting nowhere I went back into CWD, reset to factory default, wiped the caches etc, formatted system/data, and then reinstalled Stock ROM 4.0.(Rogers) using ODIN. That booted OK so I figured I managed to rid of the encryption, so again I installed CWD, and then the leaked 4.1.2 but again it's still giving me the same message!!! Arg! I've wiped all the caches a million times, formatted the system and data, reset factory defaults 10x, I've even tried flashing 4.1.2 Leak using TWRP but still no luck. I'm assuming I'm getting that message because it's still encrypted, so how the heck do I rid of this encryption? I'm thinking I have to re-partition the internal SD? Please help, I'm eager to try the new 4.1.2. Thanks
No amount of wiping /system, /data, or /cache will remove the encryption settings/keys because they are not stored in any of those partitions. They are stored in a partition that is not accessible by 'ordinary means'.
Did you perform the factory reset in CWM or in the stock recovery? I would suggest to use ODIN to flash back to the stock ICS ROM and recovery, boot to the stock recovery, factory reset from there, then reboot and make sure that encryption is no longer enabled in settings in the stock ROM.
If that's all good, then use ODIN to flash CWM and use it to flash a custom ROM.
Some info on Android encryption
Still no luck! arrg!! So I first used ODIN and install the Stock 2.3 Rogers ROM, I went into settings and reset back to factory. I rebooted, and went into the Stock Recovery however Up down arrow's worked but the enter "power button" wasn't working, so it doesn't look like i could choose reset factory from within stock recovery. Anyways, I rebooted into Download mode, used ODIN to install the STOCK 4.04 Rogers ROM, and rebooted. I checked the settings and it looked like encryption was off, or at least it had the option to encrypt. All signs anyways looked like it was off. I then installed TWRP 2.2, upgraded to 2.3, then flashed the leaked 4.1.2. And again when I rebooted, after the ATT logo I'm presented with the "Enter password to use encrypted device storage". I'm guessing it's still encrypted? And why is the stock google leaked 4.1.2 asking for the password but not the Rogers stock 4.04 ROM? Anything else I can try? It's also strange that when I enter the stock recovery mode the power button isn't funtioning as the enter key. Up down enter keys work, also if I press the home button, or maybe it was the back button it reboots. Thanks for the replies, hopefully there's more I can try. Maybe re-partitioning the entire internal SD?
Success... but lost cell unlock.
So after another Stock ICS Rogers ROM install, I went into backup and reset and did a factory reset. There's an option to delete the USB as well, which I may have been skipping... but I checked it off this time, then rebooted into the Recovery mode using TWRP 2.3. This time around I also made a few changes. I used the 4.1.2 debloat, but there's an option in TWRP to format the Android Secur... which I did... just because I wanted to nuke everything. So now yaahh!!! 4.1.2 boots up and no more encryption issues. Bad news, my phone is no longer unlocked
Idea's on the unlock?
NM... looks like using the debloat 4.1.2 I forgot to toss in the Radio, because using the regular 4.1.2 I tried again it works good. That'll be the last time I ever touch encryption.
To delete encrypted partitions successfully you need to install the android version which at least supports encryption. For example, if you install android 2.3 and you do a factory reset won't work for the internal sdcard, but probably will if you install android 4.1.2.

[Q] Help needed - stuck on CM10 boot-up animation

Hi All,
I have the Telstra HTC One XL, and have just recently attempted to install CM10 ROM - however have run into some problems that I would appreciate some advice to rectify. I had recently updated to Jelly Bean OTA.
I followed the guide on these forums - http://forum.xda-developers.com/showthread.php?t=1859478
I Successfully unlocked bootloader by following the steps at HTCdev.com
I Successfully installed TWRP Custom Recovery
I Downloaded CM10 as per - http://forum.xda-developers.com/showthread.php?t=1790032. I transferred this as well as Google Apps onto my phones storage.
When attempting to install CM10, I created the Nandroid backup as recommended, and proceeded to wipe the mentioned items using TWRP (a guide I saw said to wipe everything). This is when my Nandroid back-up got wiped. TWRP gives you the option to wipe cache, delvik cache, factory reset, system, external storage, internal storage and format data. I did alll of these, and this was my mistake I believe? I proceeded to try and install CM10 and gapps from internal storage (I had to re load these back on after I wiped everything), and the install of CM10 displayed as successful.
Upon rebooting to system, the HTC screen comes up first and then goes to the CM10 animation. The phone then stays on this animation (rotating circle) for up to 10-15 minutes.
I have read thread after thread with people experiencing similar issues, and have tried rectifying my problem with various versions of roms and different guides out there. I can still boot into recovery (TWRP) mode via bootloader, and this means I can still mount my phone's storage onto my PC and have access to the storage directory. As I have deleted the Nandroid backup though, and because the ROM's won't install, I am stuck in no man's land.
There must surely be a way to have a ROM installed (even if its back to stock Telstra) from the position I am in, it would be greatly appreciated if someone may be able to point me in the right direction.
Thanks,
Robbie
maybe yall need to "fastboot flash boot boot.img" now

Why do people keep doing this??? Just because TWRP gives you all those options, doesn't mean you should use them.
Sometimes, people will say to do a "full wipe" when flashing a ROM. But that term is a bit misleading. Factory reset (from TWRP, never from hboot), wipe Dalvik and wipe cache is all that is technically required when flashing a new ROM. Some people like to wipe more "just in case". But if you aren't completely confidant in what you are doing, keep in simple and don't make it more complicated than it needs to be.
I don't know if wiping everything is the cause of your woes, but it certainly didn't help, and caused you to do some extra steps.
Flash boot.img via fastboot as previously suggested. Otherwise, just try to re-download and flash the files agin. Its seems that some people are having troubles booting after flashing CM10 (even after doing the correct wipes and flashing boot.img). Doesn't seem to be much rhyme or reason, but just flashing again has fixed the problem for at least one person.
Thanks so much, such a simple fix! That has me booted up into CM10.
I have installed cm-10-20130107-NIGHTLY-evita and cm-10.0.0-evita , however with both of these versions, my touch screen is not working once it boots up. I can function with the volume up/down, and with the power buttons, but cannot get past my SIM card lock screen.
I noticed this thread http://forum.xda-developers.com/showthread.php?t=2083314 (no solution yet)...
Does anyone have a solution to this issue that seems a common one?
Alternatively, more than happy to get an alternative ROM on my phone in the interim...Can someone recommend me a ROM?
Again, I really appreciate the quick response to my problem, very happy my phone is in operation!

[Stock] Boot loop, wipe doesn't help

I've got a T-Mobile phone with stock updated to the last version, with TWRP 2.6.3.0 and root. Everything worked fine for a couple of months.
A month ago the phone started to boot loop with no apparent reason. I've wiped everything, re installed stock, rooted and used the phone again. I've thought it might be an app updated that screwed something.
Anyway, I've only got the basic apps on the phone and today it happened again. I've read that I need to boot into bootloader and selecr "CLEAR STORAGE", I've tried that but it goes into recovery and there I can only wipe the data. I've did that and rebooted and it didn't help.
Any other ways to fix this without re installing the rom?
I think that if you use the clear storage option, you will have to reinstall the rom. I believe it wipes the system partition as well.
If you want to do this, you should flash the stock recovery (get it here)
Go into the bootloader and select the clear storage option.
Then you can flash CWM or TWRP recovery again and install the ROM.

Factory data reset kept the photos, what else?

So I gave my old Nexus 5 to a friend and wanted to wipe the phone data.
The phone was rooted with supersu and xposed installed.
I did a "factory data reset" (under the "settings -> backup & reset" menu, NOT via the bootloader menu), and after it was done it rebooted into the new phone startup wizard mode. My friend then proceeded logging in under his Google account, and everything looked fine.
Today he tells me after taking a picture he saw that my whole photo collection was still on the phone. Why? It can't come from the cloud because this session never logged on my Google account.
Now I wonder what else stayed on the phone? I guess the Music folder, apart that anything I should worry about? Any way to flush everything that comes from my installation without my friend losing his current installation?
The phone was running a stock recovery or twrp?

twrp
Reset from the ROM settings will work to fully wipe the phone if it's running a stock recovery. With twrp installed, you need to wipe from twrp.

Ok, but now that I don't have access to the phone anymore, do you know if there's a list of what was deleted and what was kept? Apps, launcher theme and customization, application settings were indeed removed. But what about call and sms history? Saved passwords / searchi history? Download/Music directories?
Unfortunately, I'm not sure what would and would not be kept with a TWRP reset from the ROM settings.
Safest thing to do would be to boot into TWRP, perform a wipe of the data and cache, and then reboot. This will require the person to set up the phone again.
