[Q] Missing Lock screen? - Samsung Galaxy Tab Plus

Ok so i confess i was tweeking my 7.0 plus and i think i took the files out of the efs folder but im not sure. Now i its not rooted anymore, i reset the tablet back to factory settings and it's still missing. Now the question is how do i get it back? ive trived all the settings and nothing helps. Basically when i hit the power button to wake it up the lock screen is gone. Help please!!!! PS ive tried downloading one from the market but i guess whatever folder is associated to the lock screen is gone so they dont work. Thanks Gil

basic rules before messing with device:
make full nandroid backup
and for samsung devices : backup EFS folder
This is my first Samsung device and I figured this out. only hope may be reinstall stock from kies or Odin. best of luck to ya.

[Q] Galaxy s2 no service after factory reset

Hi all,
I bought the GS2 two weeks ago, did nothing but rooting it, stayed with the original gingerbread OS.
A few days ago i noticed i had no reception, i tried turning airplane mode on, and then off (to restart the connection), but the phone got stuck in airplane mode.
I restarted the phone a couple of times, but it didn't work - still was stuck in airplane mode. I eventually decided to factory reset it.
After doing this the phone was not in airplane mode anymore, but it had no service (a circle with a cross line is appearing in the top right corner).
The really strange thing is that i have no imei number, no wifi or BT mac (when entering the 'about' section in the settings menu).
It looks like the phone still thinks it stuck in flight mode.
I tried looking in the efs dir, and noticed that the files nv_data.bin, nv_core.bin, their md5's and the nv_state files, all were renamed (now starting with a dot, hidden files).
I tried removing the dots from the beginning of the file names, I tried reinstalling the original ROM... nothing helps. I have no backup of the efs dir, before the problem appeared.
I don't know how really flight mode works, but it looks like the process handling it got stuck while entering flight mode, leaving the files in this strange state. Maybe there is a 'flight mode flag' in one of the files, telling the phone it is not allowed to access the files regarding the imei, wifi and BT identifiers.
It is worth mentioning that when i start using the wifi, the wifi mac updates and appears - the same would have happened if the phone was in airplane mode.
Any ideas?
Thanks in advance,
sami
Sorry I don't know but I have *exactly* the same problem and symptoms starting on 7th Aug after 3 months of use. I didn't even root. You're not alone. I think it needs to go back to the shop.
I have the exact same problem. Did anyone find a solution to this?
Never heard about this problem before, but I have a couple of suggestions:
1. Try to power off the phone, remove the SIM card and battery, wait for a minute, insert them and power on the phone.
2. Try to wipe cache and dalvik cache.
3. Try to install a different ROM with full wipe.
Mobile Network Unavaible
Good evening friends!
I am facing a strange problem with my Galaxy S II. Last night I was using the Rom Criskello, and everything was working fine. So I decided to make a backup and install other roms just to test. I installed the rom and my device Miui NDT was unsigned, I ended up doing strange and full wipe to install the ROM GalnetMiui. But I opted to return to the Criskello Rom. This morning I realized that my phone does not make calls and even shows that the data is active, but strangely, the signal is full.
Reinstall the original rom Retail Brazil and yet when I try to make calls I get Mobile Network Unavailable ...
My simcard is old, I'll buy a new one for testing. Someone tell me if this is normal?
galaxy s2 no service
Hi all,
I had a similar problem, while using Skype I suddenly got the dreaded no service indicator.. Took phone to Samsung and they said to check if it was maybe barred from the network which it wasn't.. I was about to take it back to the shop I bought it from, then decided to remove my google account but the phone forced me to do a factory data reset, under settings -> Privacy.
I did this and then...... Happy days all was fine again )
I think it was the skype application that caused the problem but will confirm this...
Life is good again!
Hope this helps...
i having the same problem, after reboot I'm having respiration but only emergency call
it's started as i flash Lp1 modem, in the Base.b it's said Unknown, but after it i flashed KP4 and everything act normal
so i really don't know!!!
i thoght this is something in my modem F.w LP1 so i went back to factory KI4
didn't help.
changed my rom from CM9 to Checkrom v4 didn't help.
factory rest didn't do much.
i found by mistake that if i am using the sim card on different phone make a sort
phone call and putting back the sim card to SG2. only this my letting my take phone call.
I'm hopping may be some one will read my temporary solution, and will help as to find the right solution .
...
restoring the oldest CMW and EFS restore manually didn't do much
i will keep looking, please if someone got a clue ...
Thank you for all
i will keep on going till i will find a solution.
i believe that the main issue is that if i didn't delete /efs all the restoring didn't really restore this folder.
this is very risky, do a good backup with EFS-PRO
http://forum.xda-developers.com/showthread.php?t=1308546
it's all started because ididn't do a good backup!!!
pinkman, have any progress?

I really need help restoring my framework-res.apk?

Hi,
In an attempt to remove the emergency dial button from the lock screen, I got into boot loop. I had edited some xml file in the framework-res.apk, put it on the phone, but then every time I booted it up, I couldn't do anything, it would reboot and reboot... I have a backup of the original framework-res.apk, so I did factory reset in recovery mode, managed to get my phone working long enough to put the original framework-res.apk in the correct folder, but as soon as I tried to set the right permissions, it rebooted and now, logically, it reboots but it doesn't even get to the PIN lock screen...
I have had this phone 3 days now and I have no money for a new one, is there any way I can restore the original file with the correct permissions without being able to boot into the phone, the only thing I have is recovery mode with the options "apply update from sdcard", "wipe data / factory reset", "wipe cache partition" and "test redbend"
Please, I am really desperate here. Searching the internet for hours for a solution, but in most cases I just lack the knowledge to do it. Also, if it's possible, I'd like to maintain my warranty.
Please help me, I'd really appreciate it!
Thanks in advance,
rob

Flash a stock rom or custom rom for your phone. ALWAYS backup before you do any Modding or flashing...hope this helps

Yeah, I've done that now, but I can't find a stock rom of my region and I'm stuck with a qwerty layout, so now I think I'm going to restore a backup of my friend's phone (he has exactly the same phone). Hope I get everything back to normal then.
Greets,
Rob

Is there anything I should look out for before I restore my friend's backup to my phone? I'm kind of paranoid I'm going to screw it all up again...
Edit:
What I was planning on doing:
Root my friend's phone
Install ROM manager
Install Clockworkmod recovery
Create backup on SD card
Put SD card in my phone
Go into CWM recovery
Restore
Choose his backup
Restore
Boot up the phone, make sure everything is alright
Go into recovery mode
Factory reset / user data delete
Does this seem right or should I check some things first?
I thought I read that you have to have the same kernel version or something?
Since I'm running a stock ROM atm, I'm not sure if this is something I should be worried about.
Edit 2: I have already found out that we have different kernels, he has 2.6.35.7-perf-cl561624 and I have 2.6.35.7-perf-CL465576
ok first make a backup of your rom (i no your rom is messed up but do it anyways) flash your freinds backup, make sure you wipe data/system first. The reason I say backup yourrom first becasue you say your freind has a diffrent kernel, so if it dosent work you have a backup so you can restore where you started, understand?
Will do,
Thanks so much for taking the time to help me, I will post the results tomorrow.
ok let me how it came along
It worked
I created a backup on his phone, put the sd card in my phone, restored the backup, booted up the phone, everything worked great, rebooted in recovery mode and wiped user data en resetted factory settings, phone is up and running now with the original firmware. So glad it worked
Thanks again!

[q] heeeellllp!!!!!

Heeeeelllp! I was trying to get touchwiz 4.0 on my Samsung Galaxy S WIFI 5.0 running android 2.2.2 when it wouldn't let me move the apk to the system/apps folder. So i made a stupid mistake and moved the apps folder out of the system folder and into its parent folder what ever that folder is. While it was moving it started coming up with force close messages tell me that so and so had forced closed and it was just constantly repeating the force close vibration pattern. Then while it was still moving the screen went black (but still on) yet the force close vibration kept going. So i rebooted and the pattern was still going even when the boot animation was there and when the boot animations has finished i just displays a black screen but yet again there is still the force close vibration happening. It boots into recovery ok and i am rooted. No CMW or custom rom though. I was using a root browser, dont no wich one. Can you help me get my data back or even my galaxy working with my data. thanks
Now that's a realy nice title you picked there for your opened thread.
I ques a lot of people will understand your problem with that title.
Edit; maybe I'm being a bit of an ass like this sorry but I realy don't understand why people opening threads with a title like you use.
If everyone would start a thread with the title heeeelppppp imagine how far we would come.
Anyway, you write you are still able to come in recovery mode and that you placed the apps out of the system folder into another folder whatever that would be..
Can't you reverse it by digging into your folders, find the apps folder and place it back in sys?
I think that's the most easiest and only step to get your data back.
But how do you do that through the recovery? I'm only using samsung's standard.
Is it possible to connect your device to pc and brows on it using explorer on pc?
If that's possible you could cut an past the map back to the system folder?

Kies wont reconize it when i boot my device normally but when i put it in recovery or download mode it says connecting but never connects. my PC reconizes my device in the same modes but wont let me browse the files. Is there any way i can browse the files on pc.
Ok, iv'e now tried a factory reset and its still not working.
I'm going to try and flash an ICS ROM
I'm trying to get posts now so i can ask another question
Sorry but I do not understand what you are trying to explain.
If your pc recognizes the device put it in storage mode if possible.

Just flash a stock rom...your phone should work then...
And remember for thr future, before doing changes with root permissions, take a backup of your data...
And don't create a thread like this in the development section...unless you want to trolled/flamed/get infracted...
Typed using a small touchscreen
My PC would only reconize it in recovery or download meaning I couldn't put it in to storage mode. Doesn't mater anyway now I'm trying to flash a new ics rom. Bit I don't know if you can flash any Rom with odin or not and if it needs a new kernel. Do you need USB debugging to install a Rom or kernel? Im new to all this you see.
You see I don't think the factory reset did anything.
OK, I'l flash a new stock rom and see if that works.
A) put phone down. Wait. Put it in a box . Then bury it.
B) read for a week. All about your phone specs, what adb is, what the difference between CWM (clockwork mod recovery) and rom manager is, how to flash partitions with Odin and heimdall, and any other info u can get your hands on.
C) after said time is up. Dig up your phone and fix it up .

[Q] Samsung Galaxy S4 mini I9192 , soft bricked.

Hello , looking for help to unbrick a partially bricked phone that allows me to turn on and use mostly everything , it seems to reboot itself every once in awhile. I can goto Kies and and try to repair but that doesn't work , also have odin with factory file and that shows Fail every time i try that. Hoping someone can help try to get back to factory settings.
Oh and i have read for 2 days here downloaded files and tried everything i can , but nothing seems to work. And when i restart phone it seems to go back to exactly where i left when it got bad root file or something. In the phone part even after i erase calls , it shows the people that called that day every time it gets restarted.
If anyone can help and walk me through , i'd be greatly appreciated. And i've watched i don't know how many youtube vid's on trying to get this back to factory mode.
Thank you.
just go into download mode and flash stock rom through odin.....

I've tried mutiple times and always comes up FAILED.
Tried Kies option also....
Apparantly its stuck in Titanium backup mode and occasionally does a reboot on its own sometimes. But even if i try to reboot after erasing tons of stuff out of it.... it comes back to what it was or how it was. So basically the titanium even though it shows up nowhere in my apps or phone... it keeps reverting my phone back to where it was when it got messed up.....
Try this

I don't know if the fail you get in Odin may be caused by having the wrong settings. I have ran into a few tutorials online that use odin, each one had a specific way. Try running it again with all the options unchecked except for the Auto Reboot. Also make sure you place the correct file(s) in the correct slot. example: any bootloader file goes into the bootloader slot, etc. make sure its checked. Then run again, this may be the only reason your getting a fail, it may have nothing to do with Odin or your phone.
Of course disregard this message if you had already fixed you problem. Also another possible fix would be to use ADB command to push the files to your phone, I suggest looking into it, there is a good amount of info on it online. It could help down the line with future issues to know ADB. Here is a website I found helpful, it is a guide to using ADB sideload to save bricked devices. ------- (android-revolution-

Plus I know how you feel, I just bricked my phone too and I know how agravating it is when nothing works.
Good luck and let me know how it goes

[Q] Go Clever Tab R75 Factory Restore

Hi All,
This may not be the correct section for this topic so feel free to move if there is somewhere more appropiate.
I have a GoClever Tab R75, when setting it up i created a new Gmail account and what i considered a secure obsecure password with no recovery options (I know it was stupid).
The device has fully powered down after several weeks and of course i cannot rember the password, I tried the passwords i used on previous devices because they are all simular but tweeked to keep each one fresh. Now there has been too many attempts. Is there a way to do a factory restore, bearing in mind that there is no vilume buttons and the reset button is only a power reset button. I did try flashing the firmware to see if it may lead to a way to access the boot menu to do this but it didn't help and obviously the firmware flash dosn't interfeer with the data partition so the lock is still in place.
I don't know if it will work but i am looking for a micro usb keyboard with a volume button so i can try but don't expect it to work,
Any comments or tips would be appreciated,
Alan
