hello ,
suddenly my s2 won't read any sim card and it's always on flight mode ! i tried to restart the phone and it didn't work , also tried to take the battery and the sim card off for a while and it didn't work also , i did factory reset still nothing.
- the sim card worked normally on another phone
- the phone is running on android 2.3.5 because we didn't get the ICS in the middle east for some reason.
- the phone is not rooted.
- kies doesn't recognize the phone anymore .
so how do i make it work ?
and sorry for the bad English because I'm not a native speaker .

sorry i mean 2.3.5
I'm pretty sure you EFS folder is messed up. There is a guide in general to recover it altrough most likely it won't. Other way is to contact xda member odia, I think he can recover it.

Do one more factory restore but this time without Sim card and SD card.
Use the dial code to wipe.

Check first your IMEI is correct .
What do you mean by not read sim card network or you cannot read the data on the sim contacts etc .

the network doesn't work and i can't show the data , it basically tells me to "insert the sim card" so it's like the sim is not even in the phone at all.

Then it may not be you efs folder (IMEI!) becoming corrupted after all! Try cleaning the contacts on your sim & inside your phone & make sure none of the pins are bent or broken internally also, then try somebody elses sim card in your phone first before replacing your own! If your sim works in another phone then it's got to be something to do with the contacts/pins, as you haven't flashed your phone or anything to corrupt stuff in the first place!!

Annoyed with Android
I have the exact same symptoms except I did not play around with any software updates or “internal settings”. The memory on my phone was filled with photos I took over the weekend and some apps refused to start up because of the lack of memory. Probably the mistake, I took the SD card out to try to read it from my Win 7 notebook, because the “Gallery App” did not want to open to allow me to delete of some images to free up memory. (Well why not, most other equipment allow their SD cards to be read by Windows.)
Whatever the reason the phone is completely stuffed; the SD card is not recognised and that result in no phone connection!! The phone can't be used. This is absolutely ludicrous. One cannot sell equipment that can be made unusable this easily. I can understand maybe losing image/data on the SD card if I took it out, but now the entire phone is useless, and it seems (from other forums too) that it is quite a process to get the so-called IEMI folder back. I am really frustrated at this point and have a real annoyance with Android. Judging from the amount of hits returned after a Google search, this SD card problem is a fairly common one. I am not going to fix this; will rather get a new phone, one that works, and it will not be an Android phone. Yes I know hardcore Andriod followers will be all over my post, but just think a bit, this kind of problem should not happen and is really nonsense
(PS: People that moan about multiple postings, can't you just answer the question, even if there is another similar thread, do you have to nit pick on everything.)

Apologies for the double messages. I tried to fix it numerous times, but it does not seem to take effect.
Jokesy, the fact people don’t get paid for commenting here is completely irrelevant; I also have a day job and don’t have 6 hours in the evening to get a phone to make a call. Pointing out severe problems with a product is not spamming.

Posting the same thing 3 or 4 times within 3 minutes and again in another person's thread is indeed spamming.

Jokesy you sure are not very observant. You should have noticed the multiple messages were due to an editing problem. Report my post; hopefully an administrator can clear up the extra messages as sure as tax this editor cannot. Do you think for one moment I value membership of a site where some rude one-eyed geeks hang out?
To the $20 guy; the phone is not worth that much. I will probably not come back to this site, so it is pointless, but I would even mail the phone to you in its original box, free of charge, if I could.
could you please tell me how did he fix it? Because I apparently have the same problem!:crying:
Try reflashing stock ROM

Interesting...
I am in a similar situation with a t989 phone that doesn´t recognize my simcards.
Some days ago I tried to upgrade my phone to the latest official ICS using ODIN as KIES
was always giving disconnection errors before finishing the upgrade.
Finally I got my phone stuck at the download mode with an error message and a yellow warning triangle.
I thought I had a bricked phone, but fortunately I managed to recover it using an old
official ROM. The problems is that now it doesn´t recognize any simcard inserted.
The current installed software versions are:
Android 2.3.5
Base band: T989UVKID
Kernel version: 2.6.35.11
Compilation number: GINGERBREAD.UVKID

Hello please i just read your post and would need your advice, my S2 just stopped recognizing my Sim card yesterday night, i was playing a fast action game on my phone and the phone suddenly went off, when it came back on it did not recognize my Sim card any longer. I tired putting the same Sim in another phone and it worked but when i returned it to mine it still did not recognize my Sim, please can you tell me what to do with regards to this issue?
Hi, I'm a total noob when it comes to WP and Lumias, but a friend who knows me as being interested in phones has come to me with a problem.
The screen of his Lumia 800 is competely smashed. He has got an estimate for it to be fixed, but they will wipe the memory of the phone - along with all his important work contacts. He has never backed these up in any way.
He said he just downloaded Zune to try and back everything up, but it's impossible since he cannot see or use the touchscreen of the phone.
Suggestions?
JusThinK said:
If the phone can boot up successful, and can be recognize by ZUNE, then you can take backup.
You don't have to use your touchscreen for taking backup.
Use this tool to take backup.

Thanks very much. Turns out all his contacts were backed up in Live after all!
Ok, so my friend's contacts were backed up to Live but now he's asking for me to get the photos off the device.
WP7 Easy Backup Tool was suggested before, but it only works if you're restoring to the same device...
Is there any way to get the photos off this phone before he sends it away to be "repaired" (eg. wiped or replaced)? He has some irreplaceable photos of his pregnant wife and newborn child on there - yes, I know and you know he should've copied them off the phone long ago, but this is the situation he's now in!

If his device is paired in Zune they Pictures are synced automatically. Does he have a Qualcomm or DLOAD bootloader?

1. I have no idea if it is. Does pairing it require use of the touchscreen (if it isn't already paired)?
2. I have no idea. How would I find out, and is there something that can be done if it's one or the other?
I can find out tomorrow.
Thanks!
First of all there is no need for a wipe of the device when you replace the screen, sounds more like they are swapping the complete phone.
When you have Zune installed and running, then connect the phone it will attach itself and sync photos and other media files depending on settings in Zune.
Replacing the screen is a 5 minute job, you could easily do it yourself and get the parts off of Ebay so do not get fooled into any high cost repair due to labour. A Nokia Care Point will charge you about 150 GBP for a screen assy (ex labour), on Ebay they can be had for about 90.
Hello,
I'm writing this as a last refuge to console myself. I got caught up in a dangerous situation today in which I had to give up my android phone i.e. Motorola Atrix 2 in order to save my life. Since all my personal and official data was stored on the sd card, which I couldn't pull out from the phone, I had activated the factory reset - including sd card formatting - before handing it over. As luck would have it, I was pressurized to give it up before the process finished so in a bid to save the data from getting into the wrong hands, I pulled out the battery while it was erasing data from the sd card according to the dialog box. My questions is: What are the chances of the sd card getting corrupted and the data becoming inaccessible? I need to know as I'm under a lot of stress because of it and there's no chance of getting it back. I had changed my google account's password the moment I reached home (after fifteen to twenty minutes) so I also the phone would have locked out. Please respond at the earliest.
Thanks.
It probably deleted some files depending on how long the dialog was up. From my past experiences sometimes I got a corrupt card (very rare) and sometimes a few files were deleted. The only thing you can do from this point is to actually check and see it any damage was done.

It was up for 30 seconds to a minute. May be a little more. What do you think?
How much difference does it make if I change my Google account's password?

Could be a lot of data was deleted but it shouldn't be corrupt as far as I know just most likely completely formatted. So yea, tell you carrier that you don't have the phone anymore. The person who took your phone will just have to create his own Google account afterwards. Call the cops? They could trace the number and whatnot. I guess I didn't understand what I was reading the first time I read the post, you were held at life or death to give up your phone? That sounds horrifying, I'm sorry.

Being an ordinary citizen, I don't have such luxuries available in my country so I have to do pretty much everything myself. I was and it's been a terrible experience - mostly just because of my data. If he logs in from another Google account on my phone, will he be able to access my apps/contacts? I had taken the battery and sim out while it was factory resetting so he'd be asked to sign-in again, right?

Really sorry to hear that!
Quite shocked as well
Well,if factory reset is complete which I believe shouldn't take upto 1 min [still,depends on your data, ]
Then,he'll have to sign in for sure!
If you've not backed up your contacts to Sd card and he doesn't know to recover it back, then you're contacts are safe!
However you should have probably tried not removing battery at that time [I know it's easier said than done, anyways I sincerely hope things go fine and also hope you are alright]

Yes, I'm still in shock and under a lot of stress.
Factory resetting hadn't completed and it was erasing sd card when I pulled the battery out hoping it would get corrupted. To see what happens in such a situation, I went to a friend's place today who has the same phone. We used his spare sd card of 4 gb (mine was 32gb with at least only twelve gbs free) to perform the same action. I started the factory reset with sd card formatting and pulled the battery out once it started erasing (didnt give it as much time as I had given to mine. After doing that I inserted the battery again and restarted the phone to check the sd card but it had corrupted although it didn't ask me for any gmail id. That's some relief but my card had larger storage so there are some doubts as well. *sigh*
I don't remember backing them up so I'm not sure.
I wish I could...
Thanks a lot, brothers. Do let me know what you think. Its very much appreciated.
You take care as well.
Apps and contacts data are linked to your Gmail so the guy shouldn't have access to any of your data without your Gmail account. Good news that the sd card got corrupt, at least it's safe to know there's a higher chance to know it corrupted or not.
If you backed up your contacts on sd card and he finds the vcard he will restore it into another android phone! I think the sd card will got corupted!

Good to know that! I agree. I'm just hoping everything and everyone remains safe...
Just to be 100% safe, I would change the password to all my major information first. Things that have to do with credit cards like PayPal or ebay. But since you factory reset the phone it also removed the pass code you had put in it (I'm almost certain it does). Just watch yourself is all I can say, watch your online activities to see if he has any of your info.

Hello everyone,
first-timer, so I hope I won't screw up!
My Samsung Galaxy SII I9100 is broken. And I don't just mean the screen (which is what I found threads on aplenty on here), I mean really broken.
It won't turn on at all. No Recovery/Download-mode, either. The only reaction it shows at all is when I plug it into a computer via USB, the area around the camera starts heating up slightly. That's it.
The last thing I did with it was visiting facebook when my phone froze up, I turned it off and it didn't start back again. It might have been exposed to a certain high temperature from the sun when I had it in my pocket but it's unlikely it reached any temperature above 40°C/104°F.
I was running the latest Cyanogen Mod 9 for SGSII.
Anyway, this thread is less about trying to find a fix for my phone (though if you can help me with that –*cool) but instead I'd like to know if there's a way to recover the data on my phone. That includes photos and music, possibly contacts, messages and Whatsapp-content.
If there is any way to do that, no matter what, I'd like to hear about it. I'm thinking about sending it in to get it repaired but before I do, I'd like to hear about my other options.
Thank you very much in advance.
Almost zero chance. The fix is replacing the motherboard, which has the internal storage on it. A company that specialises in recovery of data from dead HDD's might (but it's a very remote chance, and expect it to be very expensive if it is possible) be able to help, but you really don't have any options (shoulda/coulda/woulda backed it up).

Figured as much... I guess I'll cross my fingers when I send the little bastard in for repair/data-recovery.
I did a back-up on a whim some months ago so at least some stuff is saved but I got some new data on it since then, so that would have been nice.
Anyway, thank you very much. I just ordered a USB-jig as a last resort but I'm not having high hopes.
Hello experts,
I have Samsung Galaxy S3, I was using messenger then it hanged up and then I restarted my mobile by pressing and holding the power switch. Then Galaxy S3 logo appeared after restart and again hanged up. Then I again restarted the phone, again at the same point it hanged up i.e. at the logo of Galaxy S3. Then I pulled out battery and reinsert it but after this it never started again not even blinked once. I have also checked on another battery.
I went to the mobile repairing shop then he said CMC chip is dead so its circuit will be replaced. Then I went another shop, he said I will flash the device but I don't guarantee about the data (stored in phone storage). I said him that it is not turning on then how will you flash it. He said I will do it yet.
Now, tell me experts that what should I do to get my phone data back? What should I do that it just turned on for some minutes so that I could take my data to SD card. My data is much important. Also tell me how did the shopkeeper say that he will flash the phone even it is not turning on anyhow.
Thank you.

If it's super important, you would've backed it up, right? Everyone I know backups their important data at least 2 times
The other shopkeeper could use a jtag to force the device into download mode (helped me to unbrick a hard bricked s4).
My 2 seconds of Googling brought me to this link.
That's what I'd assume they'd do (that's what I'd do if I was them).
As for the first one, they might be correct, or not. My strongest recommendation is to try the jtag method and if that doesn't work, I will be really surprised if they actually replace the CMC. Usually what they do is just replace the motherboard which you can do at home (there are plenty of motherboards on ebay) however, it's cheaper but your data chips would need to be transfered over to the new motherboard, which is just better to go with the CMC replacement (if they don't replace your mobo, your data is fine, if they do, it's gone with the mobo).
As for the second option regarding your data, unfortunately it's correct. However, it they get into download mode, they can flash a recovery (different partition, meaning your /data partition is safe) like twrp which they can use to make a nandroid backup and then after extracting the backup, flash new rom. Then you can restore the different apps/settings from the twrp backup file (there are plenty of tutorials on the net).
Good luck! If I helped, hit the "thanks" button

Hi,
Thank you for your reply. I am afraid, if I post my issue under that running thread then how would I get answer because that thread has already more than 200 pages. And if you are asking me to read the issue, obviously you are also a busiest person having life issues and others, you can't also read that thread and want to resolve the issue ASAP. Pardon me if I get wrong as my English is not much good.
Hi, ramiabouzahra

What I understand from this, the shopkeeper who is asking me to bring life to the phone, would use jtag? What is jtag and how can I do it at home and what thing like cables, etc do I need for this. Further what I understand, is that by using jtag, the device is forced to go into download mode. Right?
My 2 seconds of Googling brought me to this link.
That's what I'd assume they'd do (that's what I'd do if I was them).

What I understand from the given link, it is a method of flashing the device. Right? By the way, do you think that the mobile which is not turning on anyhow even by trying all methods, it will turn on by flashing the device? But again, as I read the thread that data can be gone. Again, no safety for data.

Yeah, I can do this at home as I am aware of little bit electronics. Can you tell me which is suited for my Galaxy S3 on EBAY? Can you give the link so that I could buy?

And further I don't understand what do you mean by the line "which is just better to go with the CMC replacement (if they don't replace your mobo, your data is fine, if they do, it's gone with the mobo"
As for the second option regarding your data, unfortunately it's correct. However, it they get into download mode, they can flash a recovery (different partition, meaning your /data partition is safe) like twrp which they can use to make a nandroid backup and then after extracting the backup, flash new rom. Then you can restore the different apps/settings from the twrp backup file (there are plenty of tutorials on the net).

Here the second option you mean, flashing the rom? you said in the bracket the "data partition is safe" means in this method, I can safe my data? OK, I read about twrp as per my understanding, it can get my data back? Right?
Thank you for answering me, I am a dumb. Thanks for tolerating me.

Hi, ramiabouzahra
Thanks for your reply. Here is what I understand from your reply, I give answer below step by step.
Unfortunately, I didn't because I was thinking that mobile is working fine, I will backup after a week or two but before I do this, my mobile gone dead
What I understand from this, the shopkeeper who is asking me to bring life to the phone, would use jtag? What is jtag and how can I do it at home and what thing like cables, etc do I need for this. Further what I understand, is that by using jtag, the device is forced to go into download mode. Right?

What jtag is etc can be checked out in the link below. What cables you need depend on specifically your device (it might be s3, but there are different variants of the s3).
And yes, normally that would mean that it would be forced into download mode
What I understand from the given link, it is a method of flashing the device. Right? By the way, do you think that the mobile which is not turning on anyhow even by trying all methods, it will turn on by flashing the device? But again, as I read the thread that data can be gone. Again, no safety for data.

Regarding the jtag, you can check out this great forum question and answer Keep in mind that jtag doesn't always need a controller, in my case (s4 not s3), I had to create a micro usb connector with a resistor on one of the ends and plug it into the device for it to work again
You recommend me to use jtag method? OK. And what is CMC? What does it stand for? How they replace it? Any tutorial?

I don't really know what CMC is, maybe the guy meant SMC? SMC is a common abbreviation used in circuit board repair and stands for System Management Controller so in one word or another, a chip (correct me if I am wrong, I am not super educated in the circuit board area).
I do recommend you use the jtag method since if it doesn't work, at least you can rest a sure you've tried multiple ways to revive it and not sit and wonder after the board repair is complete if there was a more efficient way to solve the issue.
Yeah, I can do this at home as I am aware of little bit electronics. Can you tell me which is suited for my Galaxy S3 on EBAY? Can you give the link so that I could buy? And I hope, I would able to transfer chips on the new mobo, just locate the chip for me which is to be transferred. And further I don't understand what do you mean by the line "which is just better to go with the CMC replacement (if they don't replace your mobo, your data is fine, if they do, it's gone with the mobo"

Are you sure you can do it at home? It isn't normal solder, it's more of a ballpoint solder requiring to heat up the board to let the solder flow and then extract the nand chips. I cannot give you link since I don't know specifically what phone you have (you stated s3, but there are plenty of s3 variants such as the s3 lte etc all with different internals).
What I meant by that line is that since the data chips are on the motherboard, replacing the motherboard means losing your data. If they don't replace your motherboard (mobo), your data is intact/fine .
Here the second option you mean, flashing the rom? you said in the bracket the "data partition is safe" means in this method, I can safe my data? OK, I read about twrp as per my understanding, it can get my data back? Right?

Yep, with twrp you can create a backup and extract from that backup apps and whatnot. So technically, your data is safe (you will wipe the phone, but you'll have a backup ). If it's photos that are the issue, you can hope that your sync was on and that you had Google Photos set up (automatically backs up your gallery).
