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?
My solution
got the same ishue on my phone you just need to do a efs restore.
there is an app on the marketplace for that
XXXmarket.android.XXXcom/details?id=net.hellcat.droiddev.ktoolXXX
(remove the XXX)
hope it helps it took me 3 days to find it and get he phone signal back
when you get the app:
press the: backup EFS to /sdcard/efs.img
then click yes verify
next run the check
press the close button
then click on the restore efs from backup(red button)
press the restore img button
press red button again
press the restore tar button
then click on the purple reboot button
and your good to go
you might night to restart after the reboot for the phone's signal to register with the carrier

HI, i need help restoring my IMEI back on my phone
Quick summary:
dropped my phone
IMEI is unknown
efs pro didn't back up my efs file - only back up that i have is one that i copied and pasted to my pc
Flashed back to stock rom - didn't restore my IMEI
Background:
a while back i my phone fell and the battery pooped out and i couldn't make any calls and such. after a while i learned that it didn't have an IMEI and i searched to find a solution.
soon after i did, i found this post http://forum.xda-developers.com/showthread.php?t=1358498 and it worked.
after that i used efs pro version 1.4.7.0 to back up my efs file which contains my EMEI number (for those who don't know).
i clicked to save it to both my sdcard and my pc
Current problem:
my phone fell and its battery popped out just like the first time and again its IMEI number was unknown. i then went to restore it using efs pro but it seemed that it didn't save it to my pc or my sdcard.
I used helmdall one-click to restore to stock rom but the IMEI is still unknown.
the first time i rooted my phone the guide i used said to copy my efs file from my phone and pasting it to my pc using usb mass storage.
i still have that file but idk what to do with it.
Can anyone please help me?
I GOT MY IMEI BACK!
I went back to stock rom using the link in my first post then i turned my phone off, took the battery out, didn't plug any power into my phone, then i held the power button for a few seconds and let it sit for 20 min without the battery or usb cable plugged in and when i turned it on i had my IMEI back
hope this will help someone one day

Glad you got it working again. Please put [SOLVED] in front of the title of your original post so everyone knows you've fixed it.
For the record, it's IMEI
From what i've been hearing- I should ditch my triumph and maybe get a samsung gallaxy2 prepaid. Until i have $ for that i thought I'd try the cygen mod.
My phone was already rooted. I tried to put on clockwork as instructed on various forums.when igot to the part about swpping the recovery image when i tried to boot into cw ( pressing power vlume up and down) all it does is vibrate with a black screen. I have to take battery out to stop it.
Then i realized I already had clockwork on the phone i forgot i had downloaded ROM manager( with the derbyhat clockwork orange eye logo) long ago.
When i plug the phone back up to computer i still get the mobile drive so is it still in download mode?
I tried : making sure my battery is charged
re-downloading various recovery images and swapping
taking the .img off the file before unplugging
making sure there no space before the word recovery
When i try and ress power and volume down the phone does nothing
when i press just power it just vibrates continuous black screen
when i press all buttons at once it just vibrates continuous
how do I get my phone back the way it was before i tried this or make this clockwork work? I've been searching on the net all day and can't really find a clear straight answer. I found some leads but the links were old and broken. I feel like a cat chasing my tail!
Also someone recommended reformatting the mobile drive so i did that and now there is nothing in that file except the new recovery img i tried to put there. No boot img or eetc. didi I make things worse??
I really need help now cuz I have no phone that works- I am constantly worried my kid might need to call me from camp and can't reach me!!
If you have a fix could you please explain it simply so a newbie or child could understand? i am not a developer or anything. Just a girl try ing to get her phone back working.
Thanx in advance !:crying:
Problem Solved
I ended up reformatting my mobile drive since i had also accidentally wiped out all the files. Then i found a link for all the files that were missing on another forum and i reinstalled everything. then i tried to boot my phone. it still did not work so i plugged the phone into a wall charger and then tried to power on and it worked.( the battery was dead). my phone was back to normal intact! :victory:
Same problem
My phone has the same problem as yours .I have been trying fo a week on multiple forums to find an answer with no success. I see someone replied to you about reformatting ,but as far as I know that would require the phone to function well enough to get into a mode of some kind . Please if you don't mind would you drop me an email ([email protected]) if you come up with a solution . It is making me crazy, LOL ..If I find a fix for this I will contact you here or you can send me contact info and I will email you : Thanks ,my name is Paul

Well help hath arrived if you don't have it fixed already. I know XDA doesn't like it when we link to another site, but the Triumph guys normally hang out here: http://androidforums.com/triumph-all-things-root/ It's just more convenient for us. Honestly we were thinking about XDA due to XDA's excellent uptime (XDA is great, by the way) but AndroidForums stopped crashing years back so we stayed. Nothing against this site (I use both about equally) but we can continue the discussion here. Also, your fix lies here and don't read most of the first posts. The actual fix was from g60, and he kept a back up of Austrie's old files on his new server. The original link went dead, but you can find what you want here.
Greetings,
I have a jiayu G3S QUAD CORE MTK6589. I have been using it for over 6 months with no problem.The phone came rooted and i was happy with the ROM it had, so i didn't try to change it.Suddenly today the phone could not wake up.I removed the battery and put it back but no changes.The only way for the phone to wake up is to plug it to my pc.When i do that, i get the jiayu logo and after a while the battery charging image.I have tried to enter recovery mode, but i get the dead android with the red triangle sign.If i press the "volume down" button i get the factory mode, which is in chinese and doesn't do anything(i can move up and down but select nothing).
Here is the translation of that:
工厂模式（Gōng chǎng mó shì）=factory model
完整测试（Wán zhěng cè shì）=complete testing
单项测试(Dān xiàng cè shì)=single testing
测试报告（Cè shì bào gào）=test report
清除e MMC（Qīng chú e MMC）=Clear/Remove/reset e MMC
版本信息（Bǎn běn xìn xī）=Version Information
重启手机（Chóng qǐ shǒu jī）= restarting the phone
I have tried flashing this ROM
needrom.com/mobile/jiayu-g3s-2
and everything seems to be completed correctly but there is no change to my phone's condition.
Can anyone please help me with that?Is there maybe a way to install the OS from the scratch?
Thanks in advance
I have to answer my own question:
It is kinda stupid but the problem is somewhat solved.This is what had happened:
The power button was damaged!!! so when my phone turned off from battery i couldn't turn it on.Trying to put it to recovery mode and seeing the dead droid made me think that the os had crashed, so i tried to flash a new rom.The phone though wouldn't turn on (at that time i didn't know the button was not working) so i thought that sth was wrong.After flashing new rom for more that 20 times with all versions of sp tool and all roms i could find in needrom, the phone turned on!!!!But i had forgotten to put back my sd card.So i tried to turn it off and found that sth is wrong with the power button.I teard the phone apart and found that there in not good contact at the button film-cables.So i will have to do some soldering on that or order a new button...The good news is that through this I got familiar with all? the methods that i need to know for android.
So to sum up
IF THE PHONE DOESN'T TURN ON, CHECK THE POWER BUTTON FIRST!!!
Hi guys got the Excelvan ET704 tablet (phablet) it's a 3g phone tablet dual sim unlocked.
I had made a backup with MTK droid tools,and upon restore i got nothing just a black screen now,so i tried a hundred times to get something from the backups to run i flashed it 1st time with the recent backup made,and it then failed to register the usb saying unrecognized,eventually i did manage to flash only one of the earlier backups by holding volume down and pressing the reset hole at the back whilst holding volume down button.
Then i inserted the cable the flash succeeded and it said done,but on the bottom it says 29gb+4096mb unknown emmc? I know it's a 4gb rom what is going on and does anyone know where to get a rom please the model number is known to be a K7206 it's build is K7206_QSVGA_V10 an it's 1200x600 resolution a 7" tablet phone dual sim and 3g,.
Looking in mobile uncle tools said bird72_a_wet_jb3 ,other than this i am completely stuck,i have emailed excelvan but obviously it being tonight there's not going to be a reply any time soon if at all.I really could do with the firmware for the device,i tried to fromat before but it fails every time there is also no preloader file in the backup?
Here is a screenprint of a flash with the firmware i backed up and it ends with a green box after a yellow bar at the end.It's a screenshot of a flash in progress showing what i get happening as i flash it.
Excelvan ET704 recovery
I don't answer you questions but maybe I will able to help you if you or someone help me unlock my Excelvan then I can dump ROM for you.
My Excelvan ET704 is blocked by some kind of police virus.
I have no access to any settings, apps and etc..
I need to restore it to factory default but don't know how to get in recovery mode. Combinations of hardware buttons PWR +VOL UP or VOL DOWN don't work.
Someone know how to restore it or unlock?
