Spoon feeding is not allowed here.
If you're a Android n00b and want to know how to root or flash custom or stock roms I suggest you do some reading/research. We have plenty of Q&A and guides that cover this.
Asking "how do I root" is a silly question to ask because its already been asked and answered so just look/read.

If you lost somehow your IMEI number(0 under *#06#), rooting the device won't help.
First, before any movement, backup your data and then restore defaults. Maybe it's some king of bug?
Settings->backup &restore -> restore defaults, erase memory.

yea i did type *#06# but imei is not showing up . its empty!! its not a bug. its a corruption in the imei ... i have no idea what to do now

First, relax. Its just a phone.
If the phone is still under warrenty - get it replaced/fixed for free where you bought it from.
If not, try to recover the iemi like it's explained here: http://forum.xda-developers.com/showthread.php?t=1264021

thing is its hard to relax because i dont have an altrenative phone and it costed me a lot . my warranty just got over a few days ago another problem ........
well i checked out the link . but i dont get the cmd, adb shell part .. the whole 8th point i dont get it ???.

If you don't get it, there isn't anything further anyone here can do to help you. Send it to a Samsung service centre/authorised repairer, or ask local mobile repair shops. This is not something you're going to fix yourself.

hmmm.. well i went to them . they asked me to change the motherboard whith a total cost of 800 dhs.. which my parents wont give

CMD is command line - like MSDOS or Linux terminal. ADB is not something that you'll get by asking questions and getting answers, you need to read about it and understand it. It will take you a couple of days to figure it out.
I'd try going to several different phone shops/labs. Hopefully they will diagnose the problem without replacing the entire PCB. It's worth a shot.
If every shop says that you must replace the board, ask around. Maybe one of your friends knows someone who is able to fix this.
From what you described it seems like water damage or other hardware fault.

If you want anyone to -try to- help you get your phone back you should at least consider searching for easy questions.
Check what ROM you are on and perform a search at xda or google (or both).
Now, are you sure warranty is voided? if it was 2 years you still got time....If you root your devices, warranty will be off the table for you.
Seat back and get you sh*t together, take a long breath and then report back to see what's up.

Hi all,
I have exactly the same issue on my Galaxy S2 on Vodaphone in the UK. It's out of warranty and not rooted. I did an IOS upgrade to ICS v4.0.3 and at that point it shows no signal and the IMEI no. is blank after dialing *#06#. Somehow it has lost/corrupted the IMEI no. during the upgrade.
Is the only way to recover the IMEI no. to root the phone? Or is there another method?
Thanks all!

An iOS upgrade ? No wonder you borked your IMEI
Go to Samfirmware, find the latest stock rom for your carrier/country. Flash it with Odin. How ? Search/read/learn. If you're lucky, yours is a case where the IMEI disappearing is a transient thing & doing a 'good' flash of stock (as opposed to the update that obviously barfed in some way - I presume you're talking about an OTA update as opposed to something you did manually ?) might well fix the problem. We've seen a number of similar problems on here lately.
If you're unlucky, you're SOOL & it ain't coming back. Rooting it isn't going to magically fix it unless you have an EFS backup, which you won't have if you're someone who's never rooted their phone. Take it to a local mobile repair shop, they may be able to help. A Samsung service centre/authorised repairer will also fix it for you regardless of the warranty status, they'll just charge you more than a local mobile shop who isn't an authorised Samsung repairer will, likely.

Thank you for your response! I took the S2 to a phone repair shop, the guy tried flashing it back to stock IOS but this failed. He ended up replacing the motherboard, all fine now. Would like to find out the safest way to upgrade the IOS to Jelly Bean now, it's currently running Gingerbread v2.3.3. Any advice appreciated, in the meantime will do some reading up.
Thanks all, great forum!

Okay i might be able to help you .but tell me your model number ......
if its GT-I9100 then you can update easily ,but if its gt-i9100G or smoething else,im nt sure i cn help .. u might have to do some readings ..

The model is GT-I9100, I managed to successfully upgrade the IOS to 4.1.2 using Kies. Perhaps I should've done that first time around instead of selecting Settings-About Device-Software Update over Wifi - which resulted in the phone losing it's IMEI no.
Many thanks for the replies!

okay dude .. enjoy your JB ...

[Solved] help with a soft-bricked phone ((urgently))

Somebody help me with my issue
I was having RR ROM with Siyah 3.3.3b Kernel and the secondary boot is port JB
I was on the secondary boot and I was restarting I found that the device is crashed
I thought it’s the kernel so I booted the phone to the download mood and flashed a kernel again and its not working also
I tried to add new software from Odin and it was giving me errors like | failed to mount emmc
I searched the internet and by mistake I flashed the device with i9100G PIT files and I re-partitioned the device and also I flashed a new boot loader not only this but also during the flashing process my pc crashed and it restarts leaving my device with no life
I can’t even turn the device on or go to download mood or anything the only thing that let me have a faith that the mobile is still a live that its getting heat while the battery is plugged in
Anyone can help with this?
Hard Brick?
As far a I know flashing a wrong bootloader hard-bricks your phone. the bootloader is what loads first, ans then in turn loads the rest of the system. if your bootloader is broken, it will neither load recovery, DL-Mode nor the system. maybe you can find a solution to this by searching for wrong bootloader or anything of the sort.
if everything fails you would need to get a new motherboard or whatever it is called in an android phone. there are guides in this forum on this, I once used this one: http://forum.xda-developers.com/showthread.php?t=1253969 althogh the photos only seem to work with the old xda2010 theme.
I hope it is not what it looks like and you get your phone up and ruing again.
Bootloader had nothing to do with what went wrong for him. He flashed an I9100G pit file to an I9100.
OP, unfortunately there's nothing you can do at this point short of JTag service, or visiting/sending the phone to a Samsung service center.
find a repair center that preforms jtag near you, it should cost you about 40$

am living in Egypt we don't have Jtag services .. i saw what they can make on you-tube and am still in warranty so i don't know what to do should i pass it by the warranty should they let me pay or it will be free ?
From what i've read on this forum its better if you try to send it to samsung for warranty your chances to get it repaired is 50/50 just play dump you have nothing to loose
thanks guys for your reply i think i made an issue with the MB BOIS firmware hence it has to be hard flashed in the warranty so am scheduling the same on next Friday i hope that they will not ask for money as it was on a custom ROM
because here in Egypt Warranty is make fool of us and they always take much money to fix noob issues so guess what they can do regarding mine.
I've got my device from the warranty , its working fine now .. i need to inform you that Warranty in Egypt confirmed that flashing custom ROMs is not voiding the Warranty its just black listing the device in their records .
They are flashing boot loaders smoothly.

Galaxy S II 100% Bricked

Hello XDA,
I was trying to flash CM9 on my Samsung Galaxy S2, was running Stock ICS XWLP7, successfully flashed it, proceeded to CWM and Wipe Data/Factory Reset unaware of the eMMC Brick Bug, went away during the wipe process, as I came back, I saw that the phone was completely bricked. Download/Recovery Modes don't work, Odin doesn't recognize anything, can't charge phone, the phone is cold and dead. Jig or JTAG don't work either.
btw. I can't get it replaced.
1. Is this the infamous superbrick?
2.If yes, what can I do about it? If no, what is it?
Yes, looks like you've encountered the infamous superbrick
The only way to revive a superbricked phone is to send it to Samsung service center.

Then he needs to pay for a motherboard replacement, simple as that.
Also, by the way, why did you create this thread when we already have plenty of this exact topic? You could have diagnosed this easily by looking at one or more of the threads we already have without creating yet another one and waiting for same answers.
Is it insured under home insurance or bank/credit card? Otherwise it's buy a new phone or send back to Samsung for repair and pay. Good luck.

Because all the fixes were like, flash X from Odin, but the phone doesn't get recognized by Odin.
The phone was bought from Germany, Samsung Turkey refuses to replace it, it must be sent to Germany for replacement.(if possible)

And in those cases the devices were never actually "bricked" at all, those were just n00bs who couldn't fix their system boot problem and like to describe their device as "soft-bricked". In your case your device is actually "bricked" what the n00bs call "hard-bricked" when in reality their is only "bricked". If you can flash via odin or recovery your device is not bricked.
In your case you wiped your device with a buggy kernel (which has been discussed at length as I said) and only option is mobo replacement.

No service/network after Root + Custom Rom Install - PLEASE HELP ME.

I have an S3 i9305 4g lte version, on orange network uk. I rooted the phone using CWM. Then installed the Panorama ROM, using the guide on here. And yes i have used the search function, followed pretty much every guide there is. Still no solution. Im beginning to think my phone will forever be caught up with this problem
on top of there being no service. The phone itself has started to randomly turn off, and also lags!
I regret rooting lol just wasn't meant to be.
Can anyone help me? Literally, I would be so grateful if someone can actually help me fix this problem. I basically just want my network service back, regardless of unrooting or not.
Thanks a million in advance!

Also, if you're unhappy with the ROM, flash another one. Plenty of good roms out there.

[Solved]IMEI has changed, No Network, No Phone Calls (Any Suggestions?)

My IMEI was 353************** and changed to 0499901********. So I am not able to make any phone calls right now.
I have no idea how it happened. I am flashing ROMS for 8 months. I have no EFS backup because i didn't know how much important it was [I AM REALLY STUPID ]
I know 049999**** is a test imei. In every forum there is a solution for SGS / SGSII. There are things for SGS3 but threads are very old like 5-6 months ago and they don't work...
I've tried installing softwares called NsPro or Samsung Tools. But I know they need some special stuffs and they are not free..
I've tried stock roms, modified Roms,kernels,modems after this happened.(Yesterday i was on 4.2.2 now 4.0.4)
So i gave up
Is there any suggestions? Any help way ? Because if I can't find any solution until tomorrow, I'll give the phone to technical service and i don't like it.
Last time I gave my phone to the service it took 25 days and they changed the motherboard with new IMEI (Nokia C7)
And the most important question : Can I update my phone if technical service fixes it? Android 4.2.2 original firmware or 4.3 , 5.0 in the future?
Sorry for bad English.I live in Turkey,Istanbul if there is anyone who can contact me.
Thanks!

Good your issue was resolved. It is always bettwe to keep a back up of efs folder. nv_data_bin would have corrupted which restored on another flash of ROM and you are lucky. Most of the time flashing an unsuitable kernel would lead to this problem.

Galaxy S3 another null&network problem..

Hi, I know are many threads here with this problem and I tried every metod like installing another ROM, installing a stock ROM but without success. My phone got broken when fell from my hand to the ground, after that IMEI is null and I can`t use network. How can I get back the IMEI or using another to work my network again? I tried with custom ROM, stock ROM, some tutorials on internet like arizandroid but nothing helped me out. Thank you guys
How do you expect a forum to help with hardware damage?
Take it to a repair centre or buy a new phone.
Ok, thank you for your reply but how could you know this is a hardware damage problem if everything is fine beside IMEI doesn`t works?
