[q] imei repair

Hi all,
Apologies but I am real new to this and not sure if I am doing it right.
My Galaxy S I9000 on day stopped receiving and making calls. To cut a long story short after a million calls to my network found that my IMEI was not the same as the one on the back of my phone and told me I have tried to Jailbreak it (whatever this means) and nobody will take responsibility for it. After much heartache I had to purchase a new phone as I really need it.
Now my Galaxy S I9000 is a pc. Works perfectly on the net, games, videos etc but cant make calls or receive them. All I can think is that my 3 year old did something to it while playing games.
I wonder if the IMEI number can be restore, this should be legal as the phone is mine and I just want to repair it.
I am absolutely useless at all the jargon so I will pretty please ask for plain plain english.
Thanks for your help in advance.

I`ts illegal to modify the IMEI.So noone can help you here.Even if that means restoring it to the original.

Flash a new stock rom. This will usually solve your problem.

If something has overwritten your IMEI details, I.e "jailbreaking" or updating firmware. Then flashing a stock ROM will not help. It's near to impossible to change the IMEI data as it is encrypted information.
What may be a possibilty is restoring the backup file located in your /efs filesystem. I have done this before and worked flawlessly
How much experience do you have within linux/android?
EDIT: Backup your /efs filesystem first.
What you will have to do first is move the nv_data.md5 to say.....nv_data.md5.old. Reboot the phone, if it is recreated, then you should be good to go to attempt a recovery to your IMEI.
You must have root access. Do not flash a new level of firmware yet. Type in to *#1234# and reply with what it says :-D
I'm going to try and find my old post on another forum which should help you.

Same question here. If it's possible, than the existence and purpose of the IMEI would be pointless.
Some googling brought up similar threads here on xda and other forums. One guy posted something like this, hopefully it will work:
Hey guys, I flashed back to JPY (single file - no 512 pit) and on reboot it came up with a load of errors. On recovery screen, I formatted everything, wiped the partition and formatted the internal sd. Rebooted the phone and everything was fine.

I cannot post link to the original topic because of my post number.
I hope this helps, I didn't test it myself (because I didn't have this kind of trouble).

Hello

Hello everybody
This is Siddharth from India. I am a mechanical engineer. I just purchased the Galaxy Note 2 a month back prior to this I always used an iPhone. I am new to the android platform and don't know how to flash, jailbreak or how to load different roms. I am very much tempted to install the moromoto00 theme on my phone but don't have a clue how to proceed. Frankly speaking it seems a lot more complicated than jailbreaking. Can anyone help me out??
Thanks in advance

Hello
I recommend you download and install the Note II Toolkit on your PC. You can find that here: http://forum.xda-developers.com/showthread.php?t=1923956
It makes flashing and rooting very simple, and everything is explained very well.
So the first step for you now is to root your phone, install CWM and then make a Nandroid backup. The toolkit will let you do all these things very easily. :good:
Those things are necessary to do first, then after that you can start flashing ROMs and themes!
Also recommended to backup your EFS before you start flashing things. Essentially, an EFS backup backs up your IMEI code in case something goes wrong you won't be left with a device with a faulty IMEI (that would be very bad). The toolkit lets you do this as well!

An overwhelmed noob

I have this shinny new powerful phone and I have no idea what to do with it. I've never got too deep into cell phones. But I want to get the most out of this phone. I pay a lot to be able to use it and I want to get the most enjoyment out of it. I've had it a while now and I haven't really done much to it.
I want to get rid of programs that is just taking up space. I want to get the best apps, learn about the phone. Customize it in cool ways.
Should I root it? Am I too much of a noob and or have too good of a phone to even need to worry about it?
Will you guys hold my hand and walk me through this phone or link me to some "lg g2 starter guide" threads to really have fun with this phone?
Thanks

Aye! First of all, welcome to the G2 community!
It's 4 in the morning for me right now, can we 'go for a walk' after I get my sleep?
Just wanted to reply so you won't feel lost and lonely, been there, done that.
In the meantime, enjoy your G2 first for what it is right now.

I feel the exact same way! Except I've had the phone for one month now.

Thanks. I bought my phone about two weeks ago. Switched from sprint to verizon after 7 years with sprint

honestly the phone is fast enough by itself with amazing battery, but if you like to get into flashing things first off
http://forum.xda-developers.com/showthread.php?t=2449670 this will teach you how to install TWRP. after that just download a rom of your choosing, more than likely the developer already root the rom for you so you dont need to do it. enjoy from there. make sure you know how to enter TWRP the hard button way... for tmobile is hold down and power button, once LG logo flash quickly let go and press the two button again. thats tmobile though.

I'm a bit of noob to the whole custom ROMS thing as well. I was just wondering what is a good program to make a back up before rooting and installing new ROMS?

TWRP (Team Win Recovery Project) and CWM (Clockwork Mod) both have backup utilities baked in. The stock full system backup will be quite large. Aside from being a best practice, it's too large to archive on the device, in my opinion. I would recommend offloading it to your PC and learn how to put it back using ADB (Android Debug Bridge) and the TWRP sideload feature in the event of a soft brick condition. Recommend you also backup and save your EFS/IMEI.

First step, ioroot.

Read and re-read on how to root and flash if you've never rooted or flash ROMS before to reduce to risk of bricking.

Hi. As someone who has very little understanding about this stuff, I'm struggling to get any use out of that guide. Is anyone else finding this?
For example:
"Ok, so if you look in the download page for your device and you are getting a zip file, this is a flashable zip, but it cannot be treated the same as an IMG file in this guide. You need to flash an older one that is a .img file, and then use that to flash the newer zip."
I have no idea how to do what it says in that last sentence, or what it even means.
Then where it starts describing option one, I don't understand what it's telling me to do. What does it mean to "push" the loki patch and the img? Where am I supposed to type that stuff in the code box?
I figured I'd just get my g2 rooted and back it up, then start reading about the stuff I didn't understand. But just getting started seems really complicated, and I'm struggling find the info I need to understand that guide. Is there a more detailed, baby step guide for idiots out there? Or can someone just quickly explain the things I mentioned about that guide?
Thanks for replies.

Firmware partiton request

Hello guys!
I'm in need of a help here. I have selected the infamous USA radio band on my Moto X Play XT1562/EU/6.0.1 and now only have access to 4G network, no calls available.
As i don't have access to a a computer atm, can anyone make a backup of modem and fsg partition using Partitions Backup app, upload it, or send it to me privately.
I know about the erase modemst1/2 commands, they work, i purposely selected the USA band again, to see, if i can fix this problem without a computer. I don't really understand why such a thing is so hard to revert...
I tried flashing the modem firmware with Flashfire by extracting the FW files from stock ROM, but no success so far. Maybe if i use the PB app and try restoring the partition from there, it would revert back to normal EU band. I'm highly doubtful this works though.
I would appreciate if anyone would make that backup and upload, any other suggestions on how to revert the problem without using fastboot/adb would be appreciated.
Thanks in advance.

Not possible. Get a computer, download whatever brand stock rom, extract the required files and flash it. You can find more information on this in the General section as there are threads regarding stock firmware downloads.

Alright, thanks for the answer. I'm still puzzled as why this is so hard to revert though.

When you flash system it ovewrites the target location and deletes what was previously there. In order to revert it you need to flash the original, and the easiest way to do so is with a computer. If you had made a backup before making changes then you wouldn't be in this situation mate

I understand, but still, just one click and it lets overwrite such critical information all too easily, if i was a total noob and not knew how to use google i would be very frustrated. Also, it's a bit of a security flaw in disguise IMO. People with bad intentions can just tap the code on the phone, change the band, and there you have it. The owner would have no calls and no idea what has happened. This is something that phone makers or devs need to take in considersation and possibly change it or remove the option alltogether. I understand laypeople are not supposed to mess with these unknown codes, but curiosity won't let us stop doing stupid things.

Do you frequently hand your phone over and let people reprogram it?
It's not a flaw, it's a feature. Not a useful one to the end user, but a feature none the less. That is like blaming an oven manufacturer, or the water company when you burned yourself on boiling water on top of it.

Alright, well i did exaggerate a bit but, still. Too easy to mess up and not so easy to revert is my point. I don't even understand why this feature is available. What purpose does it serve? Who wants to permanently switch to USA band without having an option to switch back to the old one. This is a bit mystical.

Advice on rooting my phone

Most likely this will have been asked many times, and I have done my own research already, but somehow I still feel uneasy about the whole process.
I've read this thread through and through and have even downloaded the appropriate zip file, but the ever-present risk of bricking my phone is holding me back.
What contingencies can I put in place in case this all goes horribly wrong and I brick my phone and what can I do to give me the best chances of success?
Thanks in advance

Just out of curiosity, which model note 4 do you have?
To answer your question though, there's very little chance of actually hard bricking your phone. Usually the worst case scenario is that you'll have to factory reset and lose your data and your internal sdcard data.
Just be certain that you have the correct firmware for your device that way things go sideways on you you'll be able to get back to a stock rom.

I was always scared about flashing mine too, I'll offer a couple things I did to make me feel a little easier.
1. (Correct software) Make sure you have the right software packages for your phone N910P/G/N/V...whatever, usually the first page has links to everything you'll need.
2. (Clean/Organize a little) Before you go to backup your current phone setup thin it out, delete any apps you wouldn't want on a new phone is the way I look at it. Move any pictures, Files, Music, anything you wouldn't want to lose off your internal storage (just in case)
3. (Create nandroid/backup, and store in a cool dry safe place) Assuming you're using TWRP recovery there is an option to back up your system, Data and Boot partitions (files). I believe those 3 are selected by default. I'd also recommend selecting EFS (that is the part that has all your phone's radio information in it so should you lose your network you can install that and get it back.
4. (Flash away) Make you do a clean flash the first which involves wiping everything most ROM's have good instructions on their first post.
5. ( Any problems boot into TWRP and flash your back ups) If you have the above backed up on an external SD card send a copy to Dropbox, Google Drive, i Cloud, your own computer, anywhere and everywhere you know it won't get lost, This file is a snapshot of your phone right now, treat it like gold. So if you nerf it up, install the recovery file you made and it'll be exactly like it was before.
I hope this helps ease your concerns a little, I've only been playing for a little while myself so I thought hearing from someone in a similar position would help.
Also if you run into problems always post your issue here, there are a lot of people with a wealth of knowledge willing to help here.
Good luck, most of all have fun!!
