Dear All,
I am new to android phone. I have SFR(ZTE) Staraddict. It is unlocked and I want to remove google account already entered in it as it is not mine. I search the internet and only find that the factory reset can only do that. Since it is unlocked I am not sure whether I can factory reset it as it will result in locking the phone (As far as I know). If there is another option or something I can do. Kindly help
Thank You

Thank you. But how can I carrear unlock it again. I don't have any device to unlock staraddict. Can any software be used for unlocking it or I need hardware of some sort.
Regards.

If it is carrier unlocked it will still be that way after a factory reset.

Go here:
http://www.asus.com/Tablets_Mobile/ASUS_Transformer_Pad_TF300T/#support_Download_32
Go to utilities, download the unlock app V8 on your device, install and follow instructions. Be aware! No more warranty (depending on your location, mine was still under warranty after bricking mine flashing the wrong bootloader!), so make sure what you are doing after unlocking it. Read. After you think you've read it all, read a bit more! There are a lot of manuals out here to explain everything to you, but make sure that what you read is applicable to YOUR situation. I went wrong by installing a 4.0 bootloader after updating to 4.1. Installed the wrong CM, wiped and was bricked. So read, and read some more Good luck!

Oh, and after you've done all the reading and read some more, and you've decided that all you actually want is root access, you can go here:
http://forum.xda-developers.com/showthread.php?t=2187982
It will explain you how to install TWRP on 4.2!!!! only!!!
After that, you can follow the rest of the info to get root or use TWRP for installing a custom ROM (like CROMI)!
Again, good luck

You can't load CM10.1 from the JB4.2.1 bootlader. They are not compatible. So that will be a fruitless task. Only CROMI and Energy Roms are compatible with the new bootloader right now.

Hi there, I know this is old but I am trying to root an old TF300T. Where can I get V8 of the unlock tool? The official Asus site no longer hosts it.

Here we go!
Please prepare your device carefully. Deactivate your Google account firstly. Your device should be registered at the Asus server. If there are any issues, search the thread for "unlock"!

I've been trying to unlock for a couple of days. No luck though it keeps telling me there could be a network issue. I've read a few places that it's because the device isn't registered. When i try to register the device it tells me that it should already be under 'My Products' . I assume someone has already registered the serial. Though if its already registered then my device should unlock. I've contacted support hopefully they can get it registered properly then I can run the unlocker. If anyone has had any experience with this before please let me know. Thanks

I've been in contact with Asus support and they have sync's my device to their server with the MAC and Serial. The unlocker still doesn't work for me. Says network error. They asked if the motherboard has been changed. I don't think it has, but perhaps as it's the CN(China) version it won't unlock. Does anyone know a way to unlock without Asus unlocker?

Nope! There is no other way.
The trick is to factory reset the tablet, DO NOT GIVE IT A GOOGLE OR GMAIL ACCOUNT, then run the unlock tool! Good luck!

I have unlocked the TF300TG executing the unlocker tool v8 after removing the google account from tablet (without rebooting) with internet active.

Just doing a factory reset now. Asus support suggested that it could have been a MoBo change if there was an issue before, therefore the serial I gave them to activate/sync the tablet with their system would be invalid.
ty
UPDATE: Same thing "unknown netowrk error". I guess i'm unable to sync this tablet with Asus server.
Is there another way to unlock the device without the unlocker tool?
Can't install any other ROMS or Google Play Store on this CN version, its making the tablet useless.

Did you provide to Asus the current SN of the devise? .
Please open Settings ->Status and pick up there the current SN and try the whole process again. Keep in mind there is no other way to unlock the bootloader.

Yes I provided them with the serial number (sticker on outsid of device). Also the serial number in Settings->Status. Also the MAC address in status. an App called King Root seems to have rooted the device.
I'm trying to get the play store working too.
Also Asus explained that the serial in status is not a valid one. I tried registering it myself andit does say that teh serial is invalid. only on the one on the ouside sticker is valid.
update: looks like it could be to do with being a refurbished unit, the serial starts with C2NK and does not register as valid. I found a thread about an ASUS Zenbook that serial starts with C4N0 and they were unable to register their device either.

PLEASE DO NOT GIVE THE DEVICE A GOOGLE OR GMAIL ACCOUNT!!! PLAYSTORE BELONGS TO GOOGLE.

Nope never did that, was a clean tablet after full reset no Google account.
Thanks for your help, but I think it's the refurb that is the issue, Serial number of the motherboard is not recognised by support or the asus website.

Please keep in mind the current SN of YOUR Tablet is the number shown in "Settings -> Status" not on the sticker. So you have to register your tablet on Asus website like a new one after exchange MB. Seems you never did.
PS:
※Version V8_For Android 4.2 only works with TF300T 4.2 JB of TW,US,WW CN SKU. It won’t work on other devices.

Thanks for your help.
Yes I tried to register with that serial, it's unrecognised by the website and by the support team.
I read another post somewhere who has the same issue, both our serial numbers start with a similar sequence of letters.
Another user suggested this can be when a service center that Asus use - use a different unofficial manufactured part. This would be why Asus do not recognise the serial number. I bought my device refurbed so I guess this has happened to mine.
Reference:
http://forum.notebookreview.com/threads/cannot-register-with-asus.673127/
:good:
Hence I need a different unlocking method. Which seems one isn't available.
Does anyone know how to get the play store working? Without unlocking? Root only?
Perhaps I need to somehow change the serial number like this:
https://forum.xda-developers.com/showthread.php?t=2243521
I don't quite understand how to do this on my TF300t though.

You are welcome! However using the "Thanks" button is also greatly appreciated.
Your issue is really confusing. To clear it up I would like to recommend to you to write an email to Asus Support in order to report your issue. Provide the WiFi MAC address and the current SN (Settings -> Status ->SN) of your device. Ask them to be so friendly to unlock your device. In general it takes a few days and hopefully your tablet will be unlocked.

Yes I have done exactly that. They were very helpful over several days of communication. They told me the details are invalid even in the screenshot I sent, and that they suspect a repair on the mb or swap was done.
I've found several posts with this issue in fact with a different model.
Thanks for trying. If someone knows how to change the serial number on my device that's be great, it seems doing that may fix the issue. Some users have had success using ratchet (from my earlier post https://github.com/AndroidRoot/Ratchet/blob/master/ratchet.c)

I got this tablet from my work. I'm trying to unlock the bootlaoder but no sucess... Might asus servers has been down? This tablet's from 2012, so I don't except thaht kind of services/apps using network to unlock/register are working by now?
I read on this thread to remove google account / hard reset the tablet.It didn't helped.
If anyone has somthing to try, i will. May ADB/Fastboot command will help?

Power of the phone. Now press power button and volume down simultaneously. It will boot to erecovery then select the first option.

You're missing a data_hw_XX.zip package for your region. Not a big deal. It happened to me when I didn't understand how to flash software to our phone and once when updating through FirmwareFinder. Give us more details regarding your phone (which region is it) and how this happened and we'll help you.

you have many options:
factory reset again (which may not solve tthe issue)
or
unlock bootloader> install twrp> install any 3rd party keyboards zip (search in the xda, you might get any)
or
try to connect your phone to pc and check if adb is working, if yes, follow the procedure:
1. download any 3rd party keyboard app and rename it as keyboard.apk and place it inside sdktools folder
2.open command window and type the following command
Code:
adb install keyboard.apk
now reboot your phone and try , you might have your keyboard
(ask me if you have any doubt regarding this procedure)
or
you can even do a complete firmware flash of update.app through dload method (easiestt of all the above methods, but you will lose all the data inside your internal storage)

I solved, i reinstalled b131 firmware and keyboard appears, i bypassed google verification and i make the updates, now it s working good, thx all.
Can you help me to unlock bootloader without appear me FRP Lock and the Enable OEM Unlock to appear grey again?

I'm hoping someone will advise me. My Honor 8 FRD-L04 is soft bricked. I did or tried to do a factory reset, had originally TWRP, the bootloader is in Relocked status, not unlocked like I want it, I did the dload process with the only thing that would load which was the Rollback from Huawei, now I can't input information on the setup screens because all I get is the stupid Google Voice. PLEASE HELP ME.
UPDATE: Never mind I fixed it. I'm not really for sure how either but I think it mainly was just persistence.

Question brick phone

help the brick to return to a living state!
I flashed the Indian version, it seemed to work, I blocked the bootloader and that's it. The phone on the key combination always reboots and shows the same thing:
the current image(boot/recovery) have been destroyed and cannot boot
It only reacts to clamping the volume + and - in the off state, appears in the device manager for a couple of seconds "Device with a USB serial interface" and then reboots again and again "the current image (boot / recovery) have been destroyed and cannot boot"
Mtk client does not work: handshake error - read them on the git that the device does not support or the exploit does not work.
What to do, how to unbrick now?

Hello Friend I was asking the same in other forum. Actually I am on the Indian firmware running OK but I want to relock bootloader. I want to be sure about the correct steps to do it and don't make any mistakes with my phone.

Got my phone fixed after locking the bootloader. Since I can't have it fixed on the service center, I looked for someone that can fix it remotely.
It's a paid service though.

It's most likely a scam
He says the phone is being repaired remotely, while it can't even connect to a PC, if I understand the phone's behavior after relocking the bootloader well. Then he mentions that it's paid. All these + you can contact them through WhatsApp is more than suspicious.
I saw a few less well-intentioned users on GT Neo 3's forum. Mostly simple liars, but listening to their comments might lead you to trouble, like when one of them claimed it's safe to relock the bootloader after installing the global ROM, he did it, and his phone works as before. I doubt that he has a GT Neo 3.
