hello xdadev,
i really need your help. I am a newbie in android world [just purchased my first android device] last month [samsung galaxy tab p6800]. since then, i was really excited to explore android world and its features where I was led to this site.
now, heres my problem: just this afternoon, at first, i used my wifi to access a shopping mall internet connection. but minutes after turning my wifi off, when i turned it on again to connect to another network, i was surprised that it wont start and when i open the settings menu, under it says error. im really worried.
had my unit restored to factory settings but still no changes. Rooted my galaxy tab but today, i unrooted it thinking that the rooting caused the trouble.
im also hoping to update my tab to ICS but with this problem, im really stuck! i dont know how to access my apps in the appstore.
is this a firmware error or a hardware problem? please help me. my tab helps me a lot.
thanks in advance. im willing to add some details if you could help me.:crying:
try to go back to the mall where it 1st connected, if it still doesn't connect, then use your warranty and ask for replacement.
7.7 is notorious for being a bit choosy when it comes to wifi, sometimes, it just stuck with "obtaining IP address" then will revert back to scanning.
I also encountered your error before, but I just simply turn the wifi on and off again
before going back to your retailer, try to totally deplete the battery first (it's like removing the battery) then charge your unit and try to connect again
good luck
the last thing i could remember was busybox got updated but failed to install. is there any possibility that the failure caused the problem?
nope

Ah, sorry, busybox could, and may very likely be the culprit! An older version did just that to my (I have the 6810), and a number of others, tabs.
This was for Stericson's version 8.0 and here was his reply to my email:
Sadly you fell prey to a bug that was in Version 8.0 of my installer. I fixed it in 8.1, but it seems many still got the bugged version.
To fix the issue, you need to reflash your current rom. You do not need to wipe or clear any data.
You can also look in this thread: http://forum.xda-developers.com/showthread.php?t=1691410&page=2
It has an update method that should fix your issues.
Again, I apologize for this error
Please let me know if you need anything else from me.
I did just that and reflashed my rom using Odin and then re-rooted. I haven't, since, re-installed Stericson's busybox although later versions supposedly fixed the problem. I see there has just been another update in the Play store.
Damn I got the same error today, also after a lot of updates came trough.
Still working on fixing it. Will restore backup first after full wipe..
EDIT : Ok just went to recovery via power+volume up , factory reset, a nandroid restore and wifi working again.
Phew.
Ah! Got my tab working again. Thanks guys for the link and comments. The (update. Zip), did fix the issue. Busybox related bug. Starting to re download my apps again since I got my tab data wiped. :-(

Not rooting my phone as of now. Will wait for the ICS first before rooting again. Tab is fully working already.

Just installed this ROM and as before, all previous Syndicate roms were amazing! But this one has a few issues id like to question. Biggest problem is when i turn my Epic off, it wont charge. It stalls at the battery loading screen. It just shows the "working icon" and doesn't go away. I have to pull the battery. Perhaps this isn't the rom, but i've never had this issue until now.
Second thing, a FC for "gapps" keeps coming up. Dunno why, never did before, perhaps a re-flash of the ROM would fix it. It's just a pain setting everything up over and over.
If anyone could help, I couldn't post this to the ROMs Specific thread because i'm a noob and havent posted 10 times yet, so here i am. Thank you in advance for all your help and knowledge.

The battery issue is an issue with CWM3.0.6... so i was told. So it isn't rom related. As for the gapps, I don't think they have made a gapps yet for this rom...

Roam Control
I have Flashed this ROM from supernova didn't like the battery drain so I wiped and went back to where I was before with my nandroid back up but Kernal was still stuck on twilight. I then reflashed this rom after using the samsung odin to get back to stock then the one click root from AC where you can keep data phone frooze on samsung re-odined from the ROM's OP to get CW3 and ext4. wiped 3x and flashed got a bad flash rewiped and flashed and it's finally working kind of.
I am in a place where we have no sprint 3G which is fine as @home in on wifi. Android market doesn't work unless on wifi. when off wifi it always says it looses connection or needs a connection (this never happened on any other rom I've ran before) it is way slower if I ever do get to download anything. Also other apps such as world war say I have no connection half the time as well. I used to use Roam Control from the market to get better service as I get zero in the office with sprint but now I can't even get that to work everytime I try and hit roam in the app it says to purchase from the market when I already have.
As i previously mentioned wasn't happy with the battery drain. so I have tried re downloading the zip for ROM and the new twilight fix. still losing a percent or 2 every 15-20 min seems pretty big drain compared to the supernova I was running and the midnight 4.1 before that. any help would be awesome. I wish I could put this in the ROM's thread but this is only my first post on xda. not a fan of that rule.
Re-download and reflash. Be sure to wipe 3x before doing so!

Gapps is baked in the rom, and I'm gonna try and reinstall everything. Ill post again with my experience.

If you are having issues, then I would suggest doing EB13 + EXT4 with ODIN and then doing a fresh install. The rom has been nothing but stable for me. And if you use titanium backup or some other type of app restoration then I would suggest only restoring apps with data in only the apps you really need. Otherwise you are going to run into trouble.

Can you try a fresh uninstall and re-install of Roam Control through the market? Then just make sure you have a signal the first time you change the roaming mode. Send me an email at roamcontrol (at) gmail (dot) com with any questions. Thanks!
Ok so, using CWM, I just wiped and cleared the cache a bunch of times. Not all gapps were there. Just market and contacts. I had to install gmail, search and others. I'm not getting ANY FC's. Its smooth as butter now. Now to fix the battery lock up problem. Is there a EB13 tar with the EXT4 CWM included? I'm sure someone has done it by now. Plus, this is the first version of the 2.2 rom. It can only get better. Thanks for your help fellas.

Thanks for the info on that chat help. I talked to them a bit consensus is another odin, wipe, and flash . I've tried so many times already i'm starting to get frustrated, oh well, all part of the experience right. I just got home so we'll see with new downloads of all files I can get this baby running.
Hi guys thanks for the awesome ROM
I just wanted to mention I am having the same email issue with my IMPAP AOL account, at first I was using IMAP SSL 993, I deleted the account and readded standard IMAP 143 and I am having same problem. I know you guys are aware of the email issue, I just wanted to share this info with you.
Before I installed this ROM I used ES File Explorer to copy my Angry Birds highscores.lua file to SD card and then to my computer. After installing this ROM I installed Angry Birds and it was working fine, then I installed ES File Explorer. I copied back my highscores.lua file back to the correct directory. Angry Birds started crashing after this whenever I cleared a level. It turns out the file I copied back was not writeable, so I installed Terminal Emulator and did a chmod to the highscores.lua to make it writeable, and now it works fine.
When I was on stock EBE13 my TWS was 51% I was able to fix this by changing my Mobile network from Automatic to Sprint Only and then it went to 2%. I am using this on Boost Mobile so I dont think I can Roam anyway. On this ROM my TWS is 50%, changing to Sprint Only has no affect on this, and I tried toggeling Airplane Mode on and off and it did not seem to help.
Once again thanks for this superfast ROM

it was answered in post #2, the battery lockup is an issue with CWM 3.x.x. It was also posted numerous times in the Syndicate ROM thread. I'm getting tired of reading about it.

They know about the email issue and are working on it.
Not sure about the angry birds issue sorry.
for the TWS issue I still do the airplane mode toggle to fix that. unfortunately I think that will be necessary forever, I see you've tried it already but try from a fresh reboot right away and see if that works and also I've heard of some having to toggle a couple times before it working. after a reboot I just toggle 3 times just to be safe. I have not found a rom that solves this issue. That's weird that changing to sprint only helped I have never tried that nor heard of anyone who has. I'd give it a shot but I use roam control at work so maybe i'll see if it works this weekend when I'm not at work.
I hope it works out for you, I don't know too much but hope i helped somewhat. have a good one.
I was able to fix Echange email issue by replacing Email.apk with the file from this thread.

Is anyone else having an issue with call volume? I just made my first phone call since flashing this ROM and I could barely hear the person on the other end despite having the volume up as loud as it would go.
Is there a fix for this? If so, can someone point me to it?
I just recently got this tablet from someone else. (This person had no problems and is trustworthy in reporting all that was done and care taken with it, even offering on advice on things you can do with it.)
My first step was to connect to Wifi. This happened without problems.
When returning home from work where I also connected, my wireless connection(s) said "Disabled" after trying to obtain the IP where they worked fine before. The first time this happened I had to do a factory reset to solve it (hardware reset didn't do it).
Today, it is happening again. I woke it from "standby" to start using again at home and received this message. In fact, any attempted WiFi connections comes up saying "disabled" after attempting to connect and obtain an IP. Again, these are saved connections that previously worked. I know for a fact that it's not the routers.
Please help if you can. I've tried:
1) power off/up 2x in a row to no avail
2) removing and adding back the connection with the appropriate passwords
3) a factory reset but I really don't want to do that again because I'm afraid flashing it back will bring back the same problem.
3) I haven't put any new apps on it since it last worked earlier today so I can't figure that as an issue. The first time it happened a week ago was when I'd just gotten it. It has worked for almost a week without problem. I did nothing special but travel home.
SPECS:
A500 Wifi
Rooted (was unrooted when it first happened); rooted now using IconiaRoot v1.3
(previously rooted and unrooted with Gingerbreak which would no longer root)
ROM: Honeycomb 3.1 with Virtuous Picasso v.1.1.0
Kernel: 2.6.36.4-UNITY-V5-ge7dee2a-dirty
Thanks in advance.
it's a known problem with this tablet when moving from one access poin to another, introduced with the update to 3.1. you have to reset using the pin hole near the micro USB port. i use a staple.
it may take a few tries. if it never works, there's a specific file you can delete if you're rooted. if you cant do that, you will have to do a device wipe.
There is a known issue of connecting to PEAP/EAP networks, which most work networks are. After connecting successfully, often many times, it will suddenly fail to connect. It also shows the signal from the access point to be very low or non-existent. After this happens, it can also cause problems with other PEAP/EAP access points as well.
If this is what happened to you, here's the fix. Try to connect to the access point giving you problems. While it is stuck on trying to connected, click the access point name and tell the tablet to Forget it. Then enter the same access point information manually and try to reconnect. This fixed my problem, and the fix sticks for a few weeks or so until it comes back.
Interesting, I had this same problem a few weeks ago when I visited my parents house. After a couple reboots it just started magically working again and didn't think anything of it. Their router is whatever the Verizon FiOS people install when you get their service.
Thanks, GeekGuy and Falkner, but.....
I've tried both before, but I went ahead and tried both of your recommendations again (pin reset and connection attempt/forget/add). Neither fixed it.
I would like to try to delete the file that Falkner mentioned, but you didn't specify a name and/or location of it. Can you share that?
I could never find what file to delete, so I've just installed a new ROM (thanks to XDA for info on all the how to stuff).
We'll see if it repeats.
Gone from V.Picasso v.1.1.10 with HC 3.1 to Taboonay 2.1 with HC 3.2.
Thanks for the attempted help!
Just guessing but I would say your problem is solved since no reply from yesterday?
Per my last post, I've switched ROMS. As it happened randomly before, I can only wait to see if it happens again. I will post back if it does.
And....as of tonight it happened again.
Note: Different ROM working since the last post 9-26-11.
ROM Taboonay 2.1
The only thing I can wonder about is if it happens when it tries to connect to a network that is actually down such that it cannot obtain an IP that actually gets internet access. However, it was "disabled" when I brought it up before ever trying to specifically reconnect to a network to realize the ISP wasn't doing their part.
Still....no reboots, or hardware resets have worked. I'm working on an image restore of only the system from the 9.25 install of the ROM rather than a factory data reset. Not sure if that would have been better. Trying to save some of what I've done recently. Gonna have to get used to a weekly backup if this is to continue.
Grrrrr..........restoring a backup turned out to be the last ROM. After reinstalling Taboonay 2.1, I still had all my apps and found the same problem. I'm doing a factory data reset as it's the only thing that fixed it before :-(
The only "oddity" I've experienced has been since last Thursday. The Android Market doesn't even recognize now that I have another device. Have communicated with them; they are investigating and saying they have received reports of this on free downloads giving an "unable to process purchase" message. It updates installed apps, but I cannot download any new ones through market, appbrain -even the appbrain app only and not to the market app. I can download through Amazon, so it's the Market issue. Still, that shouldn't affect this issue.
If you have any constructive feedback, I'd appreciate it!
This was happening to me. I had problems with every rom I tried until the following combo: Taboonay 2.2 with Richard's Villain ROM 3.7 kernel. Every other combo would lead to erratic wifi...now it hasn't happened in 2 days. I don't know why this is happening as many of the roms I tried claim to have the wifi fix integrated. I hope this helps. Just flash the latest Taboonay and then the kernel zip file on too of it. By the way, latest rabbinate is 2.2....NOT THE ONE YOU HAVE NOW.

Hi everybody, first of all sorry for my english.
I bought an A500 on ebay a couple of weeks ago, OS was 3.2 factory, I was thinking about trying to gain root permissions and maybe install a custom rom but tablet seems to work ok and I decided to wait for official ICS release, which arrived yesterday.
After the upgrade I noticed, as others did, strange behavior of wifi connection (strong to leak) and I cannot add any widget on home screen (keeping tapped shows only choices for changing theme).
At this point I guess it would be wise to try and install a custom rom, but I’m not confident and I really need help from the start.
I understood I need root permissions, but to gain them I have to downgrade.
Can anybody please tell me what to do, using dumb-proof terms ?
Many many thanks in advance.
update: i tried to downgrade to android 3, i think i bricked it ...
after the update i get a red error "Boot verified failed" .....
Probably wont help much now that you've bricked it, but to add a widget you need to be in the app menu and switch to the widget tab. And you should try looking at the wifi settings for default action when sleeping. For some reason, mine changed to always disconnect from wifi after turning off.
many thanks for your answer
Hello.
First of all thanks dzo for an amazing ROM Updating to latest version I faced a couple of problems, with wifi. First i had ran ICS 2.0 or so for a long time since that was working great i didn't see the need to update again, but now checking the thread and seeing there's loads of updates and hotfixes i decided to go for it and update to the latest, 5.0 u20 version. I decided to clean-up first, so i reverted back to 2.3.5 official and re-rooted and installed CWM 5.5.0.4, then ICS aurora 5.0 experimental, booted it up to see it was working ( I got to the startup screen, but couldn't press any buttons as the touchscreen was not working, not sure why but i continued updating hoping it would fix) and then rebooted back to CWM, installed 5.0 update 20.. Everything working fine now, except once i try to connect to my WIFI. I insert the password like I would normally, but instead of getting the "connecting... receiving IP" etc. it doesn't say anything. I can just see my WIFI as available but not able to connect to it.
I didn't want to give up so easily, so I re-did everything, now after 5.0 experimental i installed update 2 to see if some of the hotfixes caused the problem. Yes indeed, with update 2 my touchscreen was working just fine and so was WIFI.
So here I am wondering, what could be the cause for not being able to connect to my WIFI and how would I be able to fix it? Or maybe just settle for one of the earlier hotfixes, but I would prefer to sort this thing out.
Thanks.
Got same thing but with me its on every rom.
I think its because of the GB update I did. Maybe it had an WIFI problem the one that I had

Maybe you should just do all wipes again and flash up20 again. If you really want to update, wait for a newer version and try again
Lol... Well i did restore my backup back to 2.3.5 original ROM, then update thru ALL of the updates but no luck.. Then once i was out in shops and found a public WIFI, decided to try to connect, and voilá, it connected... Now back at home i decided to look thru my router settings and switched the mode to 802.11b+g and instantly connected... So i dunno, but now it seems to work.

Had this issue since Dzo changed Aurora's kernel to 3.0.8. I don't know why but after Aurora 3.1 wi-fi can't connect to my network if it's not a b+g or just b. After I understood that the problem is in wi-fi mode on router everything went fine.
Update 21?
Good Day

I've tried: clearing data & cache of camera app, clearing the cache partition, setting default settings of the camera app, changed camera storage from SD card to internal & vice versa

Sucks no one responded to your post. I rooted my sons S7 Edge and sometime after it acquired the same issue yours has/has. I had another S7 Edge phone so I ended up rooting that one and giving it to him. I still have his old one with the camera fail issue but I've yet to try to figure out what caused it to happen. I know my response doesn't help with info or duration from OP post to reply, I just wanted to let you know that your post wasn't ignored by everyone. Unfortunately I have nothing substantial to contribute.

So I ended up putting that phone back to stock then rooting it again and it had the exact same issue yours has. I did a clean root too and the issue is still present. From there I decided to again run it back to stock and this time do a nand erase all and repartition the device. After all was finished I checked the device and I'll be goddamned... it still has the same issue. So if the problem persists after all that reformatting is it safe to say that it's a hardware issue? I'm out of ideas. Sorry I couldn't help you.

you guys offer little information at all so this is why no one helps you. Maybe tell what firmware version you flashed what root version you did etc. There is a big difference between bootloader revB/11 and the others
Holy ****. Did I just get constructive suggestions from jrkruse?! Dude if you told me I could fix my phone by sucking a fart out of a wallaby's ass I'd do it cuz the advice came from you, and if there's one thing I know it's that you know your ****. You're ****in' awesome. I feel so special now. Ok sorry about that...
Well, I'm not too sure about the OP but I can tell you about the phone I have that seems to have the same issue.
My S7 Edge is a SM-G935V on android 7.0 on update 4BQK2. Prior to rooting I put everything to stock then I did a NAND erase and repartition. No issues with any of that.
I rooted my phone from this post

I AM NOT RESPONSIBLE FOR ANY OF YOUR ISSUES! ALL I CAN DO IS RECOMMEND A GOOD PSYCHOLOGIST! Hey guys. Stumbled on this by accident. I HAVE ABSOLUTELY NO IDEA WHY IT WORKS, BUT IT DOES. THE METHOD HAS BEEN TESTED BY ME AND A FEW OTHER PEOPLE HERE...
forum.xda-developers.com
which directs to your older method for gaining root privileges.
[DISCONTINUED] ROOT Method For Nougat
DISCONTINUED New Thread Found Here This Root Method For S7 Nougat Nougat_S7_Root_2_82_All_Carriers_V2.zip Includes Fingerprint Fix [Latest Verison] Nougat_S7_Root_2_81_All_Carriers_V2.zip Includes Fingerprint Fix Nougat_S7_Root_2_79_All.zip...
forum.xda-developers.com
I also flashed Unzip the Nougat_S7_Root_2_82_All_Carriers_V2.
Then I flashed the BL file in the BL slot from the G935U firmware with odin checking "Phone Bootloader Update". I used the BL file from G935UUES4BRA1 since it's the closest update for the U brand to the firmware this phone is on (G935VVRU4BQK2)
I'm aware that there are newer methods for gaining root access but I chose this method cuz I used it back in 2017-2018, I had read all the posts in the thread, and I knew it worked.
I currently have 3 S7 Edge phones all on the same firmware and build and are all rooted with the same combo method I just explained. The other 2 phones also have xposed installed and they both work well.. expect mine says weird stuff instead of the callers information. I think it only does it if they're a contact but in the notification tab it says an example like this 5556661234;verstat=No-TN-Validation. No clue how to fix that.
The phone that is having the same issue as the OP still had access to the private/secure folder when it was rooted; which I thought was weird cuz mine doesn't and from what I understood private mode gets disabled if the phone's rooted. Maybe it only gets disabled if you install xposed? I don't know. My son had the phone with the issue and it was his first smart phone and he dropped it a few times (with a case) so I was thinking it's an effect from something he downloaded from the play store (he's 20 now but pretty still very ignorant with android). Now I'm not sure if it's a software or hardware issue since the problem persisted after the NAND erase.
Something to note about my sons old phone also is that it has 2 thin pink lines running down one side of the screen (defective/dead pixels) and when the screen turns off it it flashes once before actually turning off. One time over the phone I tried troubleshooting the issue with him and he ended up being able to use his camera immediately after rebooting the phone though once he exited the camera app it wouldn't open again. We were trying a bunch of things, force closing any app I thought would be related to the issue. Not sure what allowed it work when it did, but even now right after a reboot the camera app still crashes.
This was long ago, I've since lost the phone. But, I was on the A bootloader and on OREO rooted using @/billa's method using an ENGboot file. I tried everything possible to get the camera to work including flashing back to stock but nothing helped. I just gave up finally. @kanesglove maybe try safely updating the firmware. Hope it helps
