I guess I'll chime in.
Although I don't have a Samsung or an RC3 I have run into this before on CM7.1 along with many other users.
(Of course, a Data\Cache wipe is always recommended, especially if problems occur after a new ROM install)
Here are my suggestions:
1) Grab the free app Fix-My-Wifi from market and run it. Reboot with it enabled at boot at least once. Toggle Airplane mode on/off before and after rebooting. If this fixes it, Great, you can uninstall the app. If it doesn't fix it, you can uninstall the app and try the next step.
2) Next you'll want to remove any saved/restored APs. You can 'Forget' them one at a time if you'd like, attempting to connect after each removal, but it may be necessary to remove them all. Make sure you attempt to connect from the 'Wireless and Network Settings' too, and not from some other toggle. Reboot and Connect.
3) If that fails, it's been reported that changing the router's password type to WEP only (if I'm remembering correctly) can fix this symptom in some cases, as well as improving the data speeds through the phone. I may have the password type wrong, so try all password types that can be set as 'only'.
If you still cant connect I would redo\retrace your install, ensuring to wipe data/cache and only restoring a minimal amount of DATA with any of your backed up apps. Also, you should avoid restoring any 'System' apps\data (they're the red ones in Titanium Backup).
That's all I've got for ya to try at this point.
If it's still not working, more detail on what you've attempted so far in your troubleshooting and how\when the phone developed the problem might help another XDA'er provide you with a solution.

how about battery back up with cm7.2 mate ??? i asked u question while u r asking ,,by the if u like to say

Device isn't working properly after wiping...

So I have a problem with my Nexus 5. Yesterday I tried all kinds of different Lollipop roms and at the end of the day I sticked to Cataclysm. I liked it and my phone was all set up but I noticed there were a lot of unnecessary folders on my internal storage and a nested 0 folder (0 inside /0). I didn't like that so I thought about making a nandroid backup, storing it on my computer (together with my music etc.), wiping everything and restoring it by using TWRP and then eventually putting my music back.
So after I stored a backup on my computer, I started my device into recovery mode and chose the option 'advanced wipe'. Usually I would do a lot of research for everything I do but in this case I was a bit lazy to do that, I tried digging into the search results of Google concerning wiping but I gave up after some unsatisfying results. So I checked every box in the list, including data and system and went through with the wiping. So because my storage was completely wiped I didn't have a 'WRTP/BACKUPS' folder anymore. I made a backup from the stuff I had (which was only a few mb's) so I would have that folder again (otherwise I wouldn't be possible to locate my nandroid backup). I wanted to transfer my nandroid from my computer to my phone by connecting it through USB but for some reason the Nexus 5 didn't show up on my PC when it was booted in recovery (this sometimes happens for some reason)
I managed to do it by using 'adb push Cataclysm folder' in cmd. I went into recovery and restored my backup. My phone booted and I thought everything was as it should be. The wallpaper was black but that was logical because my internal storage was wiped, including my custom wallpaper. But then I noticed something strange, my status bar disappeared, sames goes for my navigation bar. I really have no idea what happened because I've restored nandroid backups before and everything went fine.
So then I put a clean version of Cataclysm on my phone and for some reason it asks me to insert a SIM-card into my device while it has one. I skipped that step and then it asked for my home Wi-Fi and I chose mine, then it checked the connection way longer than it would normally do. After I was done with all the steps my homepage entered my screen and guess what, my status bar and also my navigation bar were absent. It was like my cell phone was in immersive mode all the time. Then I tried flashing the KitKat factory image by going into recovery with my phone and opening 'flash-all.bat' on my PC but then it said '< waiting for devices >' while I enabled USB debugging... I opened cmd and typed 'adb decives' and mine showed up, so it was connected (although it now says 'unauthorized' when my phone is normally booted).
Then I flashed clean Cataclysm again and it again said I had to insert my SIM-card and it then again checked the connection with the Wi-Fi for a couple of minutes. When I was done with the installation I tried replacing the wallpaper with one from Lollipop but it didn't work although there was a preview available. There was again no status bar and navigation bar. I then opened chrome and went to this website and now I'm typing this on my Nexus 5 which has a permanent immersive mode now.
So I don't have much in my internal storage anymore, only a TWRP folder with backups, nothing more, not even a 0 folder if I'm not wrong. There's something wrong with my mobile connection and definitely something going on with my navigation bar and status bar. I hope anyone could help me with this because this is really frustrating becausr I tried to fix it for the last couple of hours, unfortunately without any result...
EDIT: I forgot to mention that when I was trying to figure out how to send the nandroid without being able to access my internal storage via my computer, I booted in recovery, went to 'advanced' and then to 'adb sideload' and tried that because I saw it somewhere on the internet. I somehow believe this contributed to the problem I have.
EDIT2: Now, when I try to power off my phone by holding the power button, it reboots the device instead, what's going on... And as I said, I have a black screen as wallpaper for some reason and I can't change this, but if I open my weather widget, the widget window shows up with my chosen wallpaper on the background, what kind of sorcery is this?
EDIT3: I wanted to download a terminal emulator from Google Play to do this but I couldn't get to 100% so I thought there was something wrong with the app on my device. I googled the apk and I wanted to download it from Zippyshare and when I clicked on the button 'download now', the phone showed the message 'no SD card', so I guess that's the culprit of all of this?
TL;DR My phone is acting really weird (no status or navigation bar, phone reboots instead of asking whether I want to have it shut down when I hold the power button, the wallpaper being strange, SIM-card isn't being recognised) after I wiped data and system and actually everything...

Reboot to bootmanager , flash a factory image , wipe , start over . Something must have gotten corrupted in your nandroid backup.
Regarding ADB not working , you also need to authorize the pc you are working from . You will get a prompt on your phone when connecting . If you dont , go to developer setting , wipe ADB credentials , reconnect the phone.
Also , adb push works fine for single files but it sometimes borks when you are pushing big/many files.
Edit : I hope you didn't wipe EFS as well ( though AFAIK TWRP doesn't wipe it on a advanced wipe) . If you did it's time to return it to stock and send it to LG/Google

Thank you for reading my huge explanation. After hours of searching and trying a lot of things with my device I figured out how to fix it. Do you remember I said that when I tried to flash the factory image with 'flash-all.bat' that it responded with '< waiting for devices >' ? Well, after reinstalling the drivers countless times and trying to find the culprit I realised I was trying to flash it with TWRP being open, and not the bootloader... So after I was aware of that I finally managed to put stock Lollipop on my phone, then I wiped everything and flashed Cataclysm. It felt pretty satisfying to have a working phone again, it's a pity I had to start from scratch but on the other side, I now how a phone without any rubbish.
Regarding adb push, if I would like to ever push a rom or a big file onto my phone in case I would ever have a similar annoyance, what do you recommend me to do it with?
And what is EFS exactly and what happens if I would ever wipe that? Thank in advance!

Regarding ADB push / twrp MTP mode you jst need to remember not to try and upload the entire content of a sdcard backup or > 3-4 gigs. Big files rarely missbehave , but I screwed up my SD permissions when trying to restore my sdcard ( thousands of files and about 14 gb total).
EFS is a secure partition that stores your GSM/network id and profile - IMEI and so on. AFAIK it's pretty hard to erase but it is possible if you play around with format/repartition commands. Just follow the guides and instructions on this forum and it should be fine.
Corrupted or erased EFS = no network connectivity besides WiFi . And since tampering with it is illegal in some countries the only way to fix it is by RMA/warranty.
I'm glad you've fixed it - I'm not surprised it was a simple mistake , I've been there myself ( tried for an hour to flash a factory image unsuccessfully only to realize I had my phone plugged in a USB3 socket ) .
Don't forget to make a nandroid now that you are set up with your fav. ROM - it will come in handy sometime.

[Q] No OS installed on my Nexus 5

Hello there, I am in a big problem with my Nexus 5.
I tried to root my nexus 5, and with all precautions except one Enabling the USB debugging. It installed SuperSU, but is still not root.
I thought of doing it from scratch. Then I went to recovery mode, And by-mistake wiped everything, left with no OS installed.
Now Please help me, My internet is very very slow and my data is limited 400mb. I can't download the 526mb Android L file.
Please anyone can send his Backup file, which can be restored. I just need it for week as my Internet would be recharged back, as I have to go to college and need Phone for important calling. Please help me
PLEASE! Provide me a backup file which can be restored. Any Help would be greatly greatly appreaciated.
THANKS

The nandroid backup for our device is almost 2 gb . If you can't download the stock image , how can you download that ?
That being said , try asking a friend/colleague - maybe they can download it for you and put it on a usb drive or something.
If you can't do that why not look for a place with free wifi or (if they still exist ) an internet caffee and download it there.
The most straightforward way is flashing the factory image...

A lollipop rom is around 150mb. Banks gapps is around 65. You still have around 185mb left..

Vienna calling with some problems ......

Dear all,
just registered and already huge difficulties and problems.
The story behind:
My memory-device (my brain) decided to cancel the "password-file" - so everything was lost. Not only the pattern for the phone, but all other numbers too (credit card, account numbers .......... was not very funny. Happend within 10 minutes. Nearly all important passwords are back now, but pattern still missing....)
As I could not remember the pattern, although I tried about thousand possibilities, I did a hard-reset.
As there are several programs out there in order to recover the phone-data and messages, I tried to get into the deep of Android - but failed.
Tried to root with several programs, but at about 75% they stopped and rooting failed.
I'm not very firm with root, boot and such things - so I would ask you to support me.
(I'm in urgent need of some of the data already .........)
(Needless to mention, that I did no back-up with the new phone........ I know, not very clever.)
Many thanks in advance for your efforts and assistance. :fingers-crossed:

If the phone was running stock Marshmallow, I don't think there is a method to root.

Lollipop - Android 5.0.2
Thanksfully I did not update, when phone was asking some weeks ago ....

Finally .......
Mobile phone is rooted.
After trying several methods, both .apk and .exe files, it worked then with kingroot.apk and the root.bat-file included in "Idol 3 Root". Checked with Root-Checker. So I'm a little bit proud of myself.
Happy am I ..... for the moment.
Next step will now be the recovery of the deleted data - like messages, documents and all the contacts.
Regards,
Uschi
(hopefully will sleep this night - last night I spent with searching, reading and re-checking) :cyclops:

If someone has a hint or two - would be great.
Device is not recognized as an additional drive - I knew that before, but thought, that there will be a possibility after rooting....
Thanks a lot in advance!

No hint at all?
I need the data (messages, contacts) urgently.
All photos, docs, etc. already found and back on the phone.
But still problems getting mentioned data ....
Keep my fingers crossed that someone can assist me.
Regards, Uschi

Other idea ....
As since Android 5, phone will not be recognized as "mass-storage", will it be possible to downgrade to latest version of Adroid 4.xxx, then trying to recover data via "Recuva".
If all data has been found and stored on PC, I then could updated to Lollopop again.
Or is this not possible?

at default your phone will be recognized as an MTP device (like a digital camera), so you won't see it as a pendrive ("mass storage")
if you did earlier a reset, it think you won't get back your messages.
how did you stored your contacts? sim card, local, google sync? if local only, you deleted them, when reseted your phone.

All data already recovered had been stored on the device.
When I tried the several programms available, I removed the SIM-card as well as the SSD.
So I thought, that there must be a possibility to get the messages too.
I know, that since Android 5, the device will not be recognized as "pendrive". That's why I tought about downgrade to Android 4.xxx, in order to try to recover the missing data.
Afterwards, I then would upgrade again to actual version 5.0.2.

you can´t recover contacts and messages after factory reset. Your contacts should be backed up automatically on your gmail account.

[SOLVED] Wi-fi "memory" reset on every disabling!

Hello,
I got a little problem with my phone (so freak... I'm explaining)
I got a router before but now I changed it, because I switched to another operator. But it feels like the Wi-fi of my phone is not agree with that.
I "forget" the now inexisting router I had and connect to the new one...
...But I do this each time I turn off then on Wi-fi, and even after switching off the device with enabled Wi-fi!
For now I just have to remember one Wi-Fi router (and, thank you Kika Keyboard developers who made an extensive clipboard where I can store my password <3) but figure out what it will be when I'll have to save more passwords! So yes it's annoying. And I also already lost at leat 8 router passwords because of this strange cr*p.
Fortunately I got a Wi-fi retriever app but this is not auto connecting and this is no longer working!
That was the last point: even the router password retriever app is acting like I didn't connect to a new router since its last analyze!
So could you help me fix this annoying bug?
For now I got an hypothesis: I got XPosed and a device ID changer app.
And it contains an useless but impossible to disable option that is "changing the SSID"
Default configuration make your phone to display your SSID. But not with the local variable where your actual SSID is displayed! No, with the SSID you got when you installed the app. So you can connect to another Wi-fi and still got the same SSID (perfectly useless)
Rest of my theory is that messing up with SSID display may cause network state not to be saved properly. But this is only a supposition. And this is hard to figure it...
So to corroborate this theory, a subquestion: What is the local Android variable where SSID is stored? Tried %WIFI, %SSID but it doesn't work. And I didn't found it after a quick search.
Thank you in advance!
Sorry for wasting your time with so much text :/

There are also people conplaining this problem.
In the link pasted on the top, there is a possible fixes for some fortunate people... But actually this doesn't work for me.
-First, ro.secure.storage or ro.securestorage. thing does not exist on my device. I don't even know if it existed on my device.
-Second, there is something about /efs/ss_data, a file that also not exists on my device.
So I don't know if it's because Samsung built it differently or it has been removed. Keep checking...

After a check of my backups I saw that I got none of the file and property mentionned before.
So I'm unable to know where is the problem...

If you're saying that you looked in build.prop but you don't see any lines that say ro.securestorage, you can add those lines if they don't exist. Just edit build.prop and type the line in at the bottom then save build.prop and reboot the device.

This is what I did. Uneffective.
Why? Because I never got this prop before.
I checked my backups where the Wi-fi worked perfectly in case all of this would be due to the fact that this prop vanished because of a dark and random informatic process. And after checks I finally realized that I never had this prop...
Same thing for the file I mentionned before, located in /efs. I didn't lose it because I basically never got it.
So... This means that my device save Wi-fi informations by another way. And because I don't know this way, I cannot fix it...

If you got a different router but kept the same network name and password and didn't change anything on your device, that might be the issue, your device is probably looking for your original router because the information you originally saved was saved while the other router was in use.
Try backing up your apps, app data and settings but don't backup your wifi settings or saved wifi information. Then boot to recovery and factory reset and wipe cache and dalvik/ART. Then reboot the device, when it boots to system, try connecting and signing into your network again and see if it saves it correctly.
If the backups you are talking about are nandroid backups created in TWRP, you can also try doing an advanced restore in TWRP, you can restore just the data from your previously working backup without restoring everything else.

Well, tried what you told me and this didn't end well...
I used to make a factory reset of my phone. The problem was fixed. When I connected to the wifi first time, now each time I disabled and re-enabled it automatically reconnected (auto-connect is miraculous lol)
Then I flashed data back with TWRP recovery (backup by Nandroid app because I got a classical TarFork error with TWRP 2.7.0.1...)
When rebooting to Android it spammed 1M layers of various program crash message box.
Then using TWRP I reflashed this time everything I got then rebooting to Android the bootloader freezed.
I thought my phone was dead until I realized I could boot to recovery again. So I flashed an older backup and lost some data (fortunately I backed up SMS and apk).
My device is safe now, but this misadventure taught me lots of things:
-When I did a factory reset data has been erased, but system still the same and it reworked. So maybe an app is locking my Wi-fi like this. But which?
-Nandroid backup app is NOT reliable. If your device isn't clearly identified your backups are corrupt. Gotta erase all Nandroid backups I made.

Solved. Bug due to a bad TWRP backup. Made a fresh install and everything is fine now.
Thread closed.
