How to write serial numbers to the MB - Galaxy Tab 2 Q&A, Help & Troubleshooting

I am trying to either find a legal program that can be used to do nothing more than write a serial number to a tablet Motherboard, or even find a way to create a simple program/app to do this for me. In replacing a board on a Samsung Android tablet, yellow block letter text appears on screen as well as displays incorrect serial number, anyone at all have any ideas on this. Needed for android tablets only though.
Thanks

it seems you have problem with your /efs partition which contains All Device information like serial and IMEI and MAC Address ,, If youhave a backup of it ,, you can restore it and your problem will be fixed ,, Otherwise You Must go to Samsung Service Center

What happens if you ddn't write down your device ID when you got your phone

I flashed to Froyo 2.2 leaked the day I got my phone and never even knew about device ID. What does this mean for my future

You can always flash back to stock using the following method (see link):
http://forum.xda-developers.com/showthread.php?t=731989
Once you flash back to stock, write down the ID and then do as you wish. This is the only way I can think of right now in order to get your ID. However, I thought the Froyo 2.2 leaks only changed the Android ID and not the device ID. But in any case, you can always go back to stock and write whatever information you need down.
Yeah, the problem is with the Android ID. After flashing 20+ times now, I decided only 2 days ago to save my Android ID when I flashed back to JF6. Before then, I was running with the incorrect Android ID or randomly generated ID without a problem.
And the way I ended up getting my Android ID was flashing to JF6, and downloading the app "Android ID Changer" (no root required just to view your ID)
I still have a backup copy of my JF6 settings.db file on my computer from when I first enabled sideloading. Just so happens, it's also my backup of my Android ID.
So just a thought for everyone else who comes around this thread for whatever reason, if you have a nandroid backup of your 2.1 rom, just dump the data.img file and grab your settings.db, open it with your favorite SQLite editor, and nab your Android ID out of it.
Ok, let me make sure I know what we're talking about. I flashed my Captivate to the leaked 2.2. It's rooted and lagfixed.
So, in doing so I've lost my device ID? How does this affect the phone? I haven't noticed any differences.

You may have periodic market problems. There are some games that may not work.
If it is working ok for you then go with it for now. When you are bored with what you are on and want to change roms you should and probably have to flag back to stock. St that time you can readily retrieve your id using app android id changer

i had an issue where even flashing back to stock one click wasn't rest IMEI or ID (also had changed my product code to tmobile.
Regardless your originial id can be found in multiple places
1. i believe its on the label under your battery
2. if the label is unreadable if you registered your phone with samsung website log in you can see your IMEI.

The IMEI and Android ID are NOT the same thing. They are not related in any way at all.
If you mess up your IMEI there is no way to recover it or change it without a hardware device. The IMEI ties your phone to the carrier network and is used in conjunction with your SIM card.
This discussion is about the Android ID - it has nothing to do with cell phone networks or carriers, but it is used by games and the Market to identify your device. It can be changed very easily.

not sure what your referring to as hardware device. Mine was messed up after flashing one of the i9000 roms as was my product code. Many of the custom roms assign a generic imei when installed but is usually restore to original when one click odin back to stock. In one instance doing such wouldn't restore it.
Both were able to be restored using root manager and a hex editor to correct the nv_data.bin file.
Where do you find the device id anyway?

I downloaded an app called "ID" made by "Sora Takayama" from the market. That lists your SIM Serial, Device ID, Android ID and Subscriber ID.

Actually if you look at the first post the user asked specifically about their DEVICE ID (+ the thread title is regarding DEVICE ID) which is the IMEI as i understand. The Android ID is in fact different than the IMEI (DEVICE ID) and its possible he meant to reference android id but i was simply responding to the question as it was stated rather than reading anything into it.
So to be clear my understanding is
IMEI = DEVICE ID
IMEI does not = ANDROID ID
DEVICE ID does not = ANDROID ID
-------------
and +1 on the ID app...i am going to snap a screen shot of it to keep saved on external and hard drive so i have the info accessible if something gets messed up.
Sorry I meant Android ID
What happens if you ddn't write down your device ID when you got your phone?
A little Korean dude shows up at your house, rings the bell and then laughs in your face.

Zeros for my Phones serial number

I have been looking around the forums and only found one other person that has had this issue and was hoping we could get some help. When I backed up my IMEI using This tread my serial number disappeared and now I get an error whenever I plug my phone into my computer.
When I plug it into my computer this error pops up
Hardware ID Missing
Windows cannot identify the device plugged into the
SAMSUNG Mobile USB Composite Device.
For assistance, contact the hardware manufacturer
If I have to I can revert back to stock and return the phone but I was hoping that this awesome community could help me out!

I get that error when I plug my phone in as MTP. If I switch it to Camera Mode Windows 7 pops up asking me what I want to do, browse/import/etc. I can then browse both my internal and external cards with no problems.
Edit: I don't have zeros for a serial # though
i am having the same problem still no fix?
There are much easier backup methods for the verizon variant over that thread you linked.
That being said, is it possible you applied a restore accidentally? There was a post a ways back where that happened and bad things occurred. I'm looking for the link for you, but yes there was a fix. In work now, may take a while though....

i got this error the first time i flashed a custom rom and plugged in my phone, it was in camera mode, maybe the point is that you need to CHANGE its mode period... thereby making the phone change how it talks to the computer which will put the necessary id in there.

[Q] Device Serial number differences

Hi,
I have noticed the following regarding the serial number of my phone (Huawei G500 pro - rooted - stock ROM)
When I go to System Settings\About phone\status i get the serial number 0123456789ABCDEF
But the sticker under the battery and in the package display a different one which looks like a normal 16 characters serial number.
I can only see the sticker's serial number when boot to factory settings (pressing power button & Vol -) in PCBA test.
In some other forums I read that the serial number can also be found in file /sys/class/android_usb/f_accessory/device/iSerial
In my case this file shows the 0123456789ABCDEF.
Does anybody has an idea what is happening?
Is there a way to have my normal serial number to be appeared?
Thank you
I don't know how to fix this but the same thing happened to me with my optimus v.

At least I ' m not the only one that noticed this. So you 've also checked and through factory menu or you compared with the sticker?
By the way are you rooted?
i have noticed that too on HTC phones and Samsung phones,tablets and tabs. turned to be all these chinese replicas that will bare the same look same software but different performance and lacking some software properties and features. especially in settings and camera. so now before i buy any phone, it has to be opened and i avoid any (0123456789abcdef or 00000000000000) serial numbers.

"an unknown error occurs... " while trying to unlock tf700 (with v7)

I´m having a problem with unlocking.....
I have the "an unknown error occurs, which may be a network connection issue. Please wait and try again later."
I've seen that many people have had this problem and signing up for the device tracker would be a good idea. I tried to sign myself up for the device tracker (to check if my serial number is in their data base). This didn't work, so I called the asus support and they told me that the device tracker doesn't work and that they're on it (which I highly doubt)... But I did ask them the question whether they could see if my serial number is registered there. They said that when they typed my serial number they saw that it was connected to my email-account so they thought this was the answer to the question. I don't really know whether it is, but I still can't sign up for device tracker or unlock the tablet....
Please help! (The motivation ship is sinking...)
Also I have changed all the settings correctly I think: Two-step-verification = disabled, apps with lower security = enabled, usb debugging = on, unknown sources = on
Mailing tech support
I have send the following mail to support and I'm awaiting their response....
---------------------------------------------------------------------------------------------------------
Dear Asus support,
After having bought this product of yours a couple of years ago, it now runs like a slug. That is why I would like to unlock my tablet using the unlock tool (the 7th version) supplied by your site. It is not working however and I keep getting this message: "An unknown error occurs, which may be a network connection issue. Please wait and try again later.". Now I have read on multiple forums that many people have experienced this problem already and that the fault lies with the asus server and not with my tablet. I know that you will need my serial number and mac adress which I've put below so that you can send the information to the main server in Taiwan. I will be happy to provide you any other information you might need.
Furthermore I think it is very foolish to enforce such a vague policy regarding unlocking, which in the long term will only lose you your reputation and your customers (and therefore money). All I want is for this unlocker tool to finally work. I will not stop until this problem is finally resolved, so please do not try to brush me of your shoulders....
serial number: /////////
Wifi mac adress: ////////
Kind regards,
Kostis
Receiving support
The customer support was quite friendly actually.
They did not say anything about not supporting unlocking and sent my status information to their main office immediately. They said they corrected the database, but I´m still not able to unlock my tablet. So now I really wonder what could be the problem.....
anyone????
I just had this same problem, resolved in mid-May.
I started a phone desk request since I didn't have a serial in Settings ->about tablet in mid-April. That was fixed quickly, thanks to xda.
THEN I was told that my serial number was for a motherboard, not a tablet.
After struggling to get them to understand and not just dismiss the unlock issue, I got the ASUS helpdesk to send the information to Taiwan (TW) for the server upgrade, I waited two weeks with no answer back. When I checked in, letting them know I was still waiting, they told me TW had updated the information. I had other things to worry about by then, so a week later, the tablet unlocked easily (on the third try.) The problem is, as stated in another thread, pairing of the MAC address and the serial number in the TW database.
Try a few times. If it still doesn't work, and you get the bogus network communication error, it's back to the emails. Continue by replying to the last one; they have different people answering to the same name so track by number. There are at least two servers: If they didn't state it was an update to the TW server specifically, that's the problem.
IF you get to the Google log in, and it doesn't go, or it says you have the wrong info (password, user name warning), TRY AGAIN. and again, and again. Eventually, Google will ask you if you want to change the correct setting. Check your email at this step too: I was using my daughter's account on her tablet, but Google even sent her a message stating they had blocked a hack attempt on her account... with someone who KNEW HER PASSWORD! We approved the device thru Google (links on the email) and we were golden.
(BOY did I have an issue with getting ASUS techs to even admit that there was a way to update the TW server... the ASUS device tracker is no more: ASUS won't be supporting it any longer, since Google has their Mobile Device Tracker up and running. They'll tell you that unlocking the device means you can't track too, which is definitely not true. --tested)
My daughter's 700 is now running on Crombie-KK (with patch), 'cause while she's an aerospace engineer (almost), she doesn't "get" computers.
TF 300 on firmware still (needs research), but unlocked and rooted for digitizer board update
TF700T with LCD issues, trying to resolve
Thanks XDA!!
I´m happy that the issue is resolved for you, however they did specifically say they updated the information on the Taiwan servers for me 2 times. So should I just keep pushing and telling them that they are bull****ting me and they should try again?

I would say it more tactfully; you don't have to be nasty to get decent service from them, as tempting as it gets.... As Droidbound says, "you need to be a Polite PIA." (If they send you the survey, be direct and honest, but be professional.)
I would also call the phone "help line" for the (don't tell them) serial number using only your MAC address and make sure that the information they give you matches what shows on your status screen. THEN have them check to be sure that the same serial number is actually linked to a tablet, not a motherboard. Call twice, using each call server. Add this information to the line of emails that you have already started.
If you haven't already, make sure you have the correct version of the "version 7" unlocker. Doesn't hurt to doublecheck.
Keep in mind it did take me several tries to get the unlocker to actually work, even after they updated the TW server. I have read stories of the unlocker not working for up to 50 tries, and then it miraculously does.
My TF701t is giving me the unknown error when I try and unlock, too. The machine is out of guarantee, but it had a new motherboard fitted under guarantee and I guess the problem is that it has a different serial number. I have emailed support repeatedly, giving them both original and new S/Nos and the MAC address, and they seem to have trouble understanding my simple request to ensure their database carries the correct information. In fact, I'm not sure the person responding always reads to the end of the thread because they keep repeating questions and suggestions.
I have registered the new serial number, but they say that the unlock tool still won't work because the new serial number will be recognized as a motherboard not a device.
Their only suggestion is to send the machine in as the "software may have been injected incorrectly" - does that imply that the serial number could have been set to the original but wasn't? - but as the thing is out of guarantee that will be at my expense.
Keep in mind that the 701 is a different creature than the 700. However, it does sound like the problem is the same as mine was.
The real problem is the server in Taiwan (TW) does not have the proper, updated serial number (and maybe MAC address) for your new motherboard linked to your tablet on their database. (yes, you got the correct answer, but maybe not the correct correction) This is part of the warranty work you had done, but it wasn't completed. You do NOT need to send in your tablet again. This isn't an installed software problem: it's a paperwork problem.
That being said:
First things first: does your settings information show a serial number? If so, half the battle is won already, even if it's the new one. If there's not a serial number, search xda for serial number programming: it worked for me when my tablet did not show one internally. (if I were to do this again, I'd try to put in the old serial just to see what would happen in the unlocking but I'm a maverick that way... lol)
The fight comes in when you're trying to have them update the server in TW. I think the thing that worked for me was sending an email to [email protected]. I don't know if Tien works there anymore, but the email WILL go through, and his section worked out in 2012 or 13 how to fix the issue. It WILL get done.
In the email, give them the RPA number when the warranty work was done (if you still have it), the old serial and MAC number, and the new serial and MAC number. You can openly state unlocking purposes.
Give it about 2 weeks after the email. You will want to check your ASUS account for any followup: i didn't get any communication directly, but a new RPA was started.
Loads of thanks for that. You're correct, I should be in the TF701t bit of the forum, I ended up here by accident but the problem is exactly the same and the necessary fix the same.
Mailing UK support is completely useless, they are not at all helpful, beyond offering to examine my tablet for £50 minimum charge.
My settings shows a serial number, which is different from the original, and I have given both to support. I don't think I have my old MAC address, though; but I do have the repair details so I will try your polite email to Taiwan technique and let you know how it progresses.
Thanks again. More help in one email than in multiple daily exchanges with Asus.

if this is when you try to unlock the bootloader i had same problem mine was a refurbished product
i finally fixed and unlocked the bootloader after months of trying to figure it out
i forgot what i frigen did to unlock the bootloader
i think i just deleted all my accounts like google play and gmail from the tablet and then did the unlock and worked
im not 100 percent sure if thats what i did cause i dont rmemeber well
give it a try and hopefully it works easy
Well I emailed them a while back. The email was given a unique number on their support site, but nothing has happened.
I have tried the delete all google accounts, I'm sure the problem in my case is the serial number. One unhelpful uk support reply just said "it won't work because your serial number is now the motherboard number not the machine number" and "send it in we'll fix it it will cost at least £50". Thanks a bunch.
I'm getting quite fed up with this, it should really be so easy, the poor support means I won't be buying another Asus product.

EXACTLY the problem I had.
Unfortunately, the poor children answering phones and emails only have scripts to read: they seem to recognize only key words and have canned responses. No, they don't keep notes on your account, so you get the same answers and suggestions over and over. This can be played against them, for their understanding of your problem.
You do NOT need to send in the tablet. This is a data entry problem, not a software problem.
I agree with the level of support. unfortunately, the drive for "younger workers" and lower wages that a company prefers does not corroborate with the level of brain power inclusive in anyone who searches xda for answers, let alone someone who will post. Stick to your guns, and demand (nicely, remember they're just working people) that they update the server. Check on your new RPA and see if it has gone through.....
and try to unlock again. It's been four long months.....Maybe it will work this time.

[q] rock dr.z smart cover activation

Anyone got one and can tell me how to activate it?
Purchased mine from Amazon, have scanned the barcode on back which takes me to the web and tells me its a genuine product however i have not been able to get rock app i downloaded to accept any of the combinations of numbers i have entered.
It says you need to enter the serial number but nowhere on the package does it say serial number or SN.......
Nothing else inside the box apart from the case either
Its driving me made please help.
Anyone?
You can find serial number and IMEI in Settings-About Device-Status.
I don't think it's asking for the device serial number but a serial number for the product.
Its the same
I've tried entering my device serial number and does not work. The little information I've seen on the net shows a paper slip that comes with the item that had a code on it along with a bar code for the app download .
Are you using one if these cases and can you confirm this is what you have done. Finding it very frustrating at moment
Thats the one.
Do you have a link or anything to the rock app that I should be using as I have download 2 now and the device serial number does not work with either

Can you explain clearer please. Did you get a card with your case that had a qr box and a code underneath that you entered into the app or did you just use your device serial number?
I had nothing else but the case in the box and my device serial number does not work.
Email them your concern.
Tried but no reply.
Item was purchased from amazon so should be genuine.
Where did you get yours from or do you not actually have one?
You can email Amazon instead.
I've done that and all amazon do is send your email onto the seller. They are Hong Kong based I believe and very slow to reply.
Just going to send it back as just seems pointless.
There is a blue card with a serialnumber at the bottom of the box behind the gray paper on the bottom of the box.
