Cannot unlock after upgrading- pattern - G4 Q&A, Help & Troubleshooting

I upgraded to MM v20c and had a pattern unlock set - since then I can no longer unlock. I even went to Android Device Manager and set a code lock - but still can't unlock. I have some important info on the device and do not want to reset the system. Is there any way to do it?

Just to add - I do have access to my gmail, so if there is a way to reset the lock screen do let me know.

Using ADM I can again "lock" the device but dont get a prompt to enter the code. I can also make my phone call another number - but there seems np way to unlock it. Any help will be appreciated. Thanks!
EDIT: There is no option to enter the code from ADM anywhere.
EDIT 2: I can use adb

Issues flashing a locked T-Mo Wing

Ok, so I'm sure someone will say this has been answered 100 times but I can't find it in the forums.
I have a locked T-Mobile Wing. I tried entering unlock codes but I guess I entered wrong codes enough that it's really locked. It boots to a screen asking for the Password to unlock (only shows a numpad on screen) and Active Sync won't connect to it (it says I have to unlock the device before it connects).
Hence, I'm not able to run the ROM loader tools which require me to install a CAB file on the device first.
Anyone have a solution to this?

you could just call tmobile and tell them what happened?
I'm sure they might have a way to unlock it.

Yeah.... I bought the phone on eBay. T-Mo says I need to be the original customer in order for them to provide me an unlock code.

[Q] Unlocking an LG P350 with unlock code?

Hi,
I paid for an unlock code from one of those services where you give them your IMEI number and they give you an unlock code. The problem is I cannot access this hidden menu that is supposed to appear when you enter 3845 # * 350 #
Did I make a mistake in flashing the GingerDX ROM before unlocking? Did I need to unlock it through the stock ROM first or does the ROM have nothing to do with this hidden menu?
Any help would be great, thanks.

Hey,
Try using these codes to access the hidden menu instead:
2945#*71001#
or
2945#*350#
If they don't work, maybe it would be a good idea to return the phone to the stock firmware. Often rooting can change the way the phone responds to certain commands and this is a pretty painless task.
I hope that helps.

Thanks for the reply,unfortunately neither of those codes work.
I'm going to try the stock ROM route, are these appropriate or is there a clean untouched original ROM around somewhere?

Done and working, thanks. I did need a stock ROM, the following one worked for me:

And this code was necessary 2945#*350#

[Q] Help with Unlock issue

Hi, I'm hoping someone here might have some suggestions on what to try with my following issue. I need to unlock my i747. I've gotten an unlock code from AT&T, but it flat out does not work. I've called AT&T support 8 times, and they have been no help. they say they are opening a tech support ticket to troubleshoot the issue, but each time they just come back with the same unlock code that fails to work. I'm on stock 4.2.2, it's a phone given to me that's never been rooted or modded in any way.. Can't find any reason why it would fail to unlock. Any suggestions? Thanks in advance!
What bootloader is on your phone? If you have an older bootloader, you may be able to downgrade the phone to 4.1.1 and unlock it using the free method.
Unfortunately, the bootloader is up to date and so I can't roll back. My understanding is that would certainly brick the device if you're not on the old bootloader. Can't understand why a legitimate unlock code would fail to work, anyone seen that before?
Your original post says you're on stock 4.2.2. Can't rollback once you have the 4.3 bootloader.
aha, that's a typo. sorry, meant 4.4.2.
So you're getting the prompt to enter the code and, after entering the code, it is still locked?
I enter the code and it says the unlock failed. then re-prompts. I reboot the phone and continue to get the prompt, and the phone remains locked.

Are you entering the code with a non-AT&T sim in the phone?
yes, I am testing with a T-Mobile sim card. that's what triggers the unlock prompt. thanks!
Even though you are getting the prompt to enter the code, try this:
a. Go to the Dial pad and dial *#197328640#
b. Please click on number [1] UMTS > [1] Debugging screen > [8] Phone Control > [6] NETWORK LOCK
c. You will see 3 options
d. Please click on number [1] Perso Sha256 INFO, the screen will change slightly
e. Please hit the MENU button then when the menu pops up please carefully hit BACK to return to the previous screen
f. Next Please click on number [2] Perso Sha256 ON, the screen will change again to a one line message
g. Restart the phone on the screen by holding the power button and click RESTART
h. When the phone prompts for the unlock code simply enter the unlock code provided to you
i. Your phone is now permanently unlocked!
Thank you audit13! That did the trick! I appreciate your detailed response and instructions. I don't understand exactly what we did there, but whatever it was ,it worked!

Root Method Available?

Hi Community,
I have the M2 since a few month and I'm still looking for a working root method. So far I've tried Kingroot and the official way via Huawei-Support, but they couldn't give me the code because I cannot find the Product ID of the M2 (Mine is wifi only, no dialer -> no chance to "dial" the code to get the product ID).
I read through the forums here and some chinese forums and it seems like it is possible, to use the TWRP for the X2 for the M2 as well. But of course I need to unlock the bootloader in order to be able to flash that.
Is anyone of you aware of any working root or unlock method for the M2-801W?
Any hint is greatly appriciated. Thanks in Advance!
Tested srsroot as well without success even though it says it is supported. It patches the system and reboots - but su binary isn't there after the reboot.
FRP Protection is disabled in developer options (OEM Flashing -> Enabled), Bootloader says FRP Protection is not active

I found a youtube video with the title HUAWEI MEDIAPAD M2 UNLOCK USING FURIOUSGOLD.
There it is shown that you have to go to the calculator and type in ()()2846579()() and then =. (Tablet must be in landscape mode to get the parenthesis.) This opens the project menu where I found my IMEI, although I do not understand why my WIFI only tablet has one. Anyway, it was the same as the serial number.
For the product ID I tried the same procedure: Calculator -> ()()1357946()() and then =. Shows an 8-digit number.
I then went to the Huwai site for the unlock key. After pressing the submit button, I get 'SN and IMEI are mismatched.' I will contact Huawei about this error.
Does this work for anybody else?

Works for me as well. Got also an error message on the huawei unlock side saying "The Huawei ID used to apply for the unlock code has not been used on the device for more than 14 days."
Edit: Furios Gold is a sim unlock tool. We need a bootloader unlock tool!
Thanks
It is actually possible to unlock the bootloader just fine, did it on mine. The option 3 on http://forum.xda-developers.com/med...apad-x2-unlock-bootloader-root-guide-t3212325 ie. using DC-unlock and then "fastboot oem unlock xxxxxxxxxxxxxxxx" using adb works. I have not tried the TWRP meant for X2 on the M2, but as far as I have understood it should work.

Thank you for sharing that information - unfortunately it is not working for me, DC unlocker fails to detect the tablet. I followed the instructions carefully, all drivers are present as described on dc unlocker page. I tried it in a windows VM and on HW, doesn't work for me.. (I tried autodetect huawei phone and Mediapad X2 directly)
Do you have the LTE or the wifi version? Has anyone managed to unlock the wifi only version?

I have the LTE-version, so that's probably why it worked for me.
I just wanted to let you know, that I was able to root the device with the latest kingroot apk

Is there difference between m8, m10 wifi & lte?
well kingoroot didn't work for me i have the m2 8.0 on lollipop 5.1.1
latest kingroot is not working for me as well.. any other suggestions? thank you in advance.

I have mediapad m2-801L.
I have rooted my phone already by following the guide in mediapad x2.
Well that's good that there is alternative method if kingroot doesn't work.
A. Please go to this link: here
B. I have used DC Unlocker to unlock my bootloader (costs €4) and it can directly unlock the mediapad by using their app. Please click here
C. I flashed the TWRP in the link above using fastboot.
D. I flashed the SuperSU found in the same link above and done! Mediapad M2 is rooted now.
Do you know Iif it's possible to root without unlocking bootloader? do we loose anything if bootloader is unlocking.
I have xperia z5c and I don't want to unlock bootloader because some features will be disabled
Kingroot worked for me (latest version, APK run directly on the tablet)
I have the 802L Wifi only on 5.1.1, Kingroot said that there is no root method available, but I was able to continue and got root.
Previously, i had disabled the FRP Protection (Developer Options -> Enable OEM flashing)
DC Unlocker worked for me as well - the Mediapad 8.0 seems to be supported now in the latest version. You need to set your device to manufacturing mode (open the calculator, turn the tablet around to see it in landscape mode, type ()()2846579()() and =
then, from the background service menu, select USB Options -> Manufacturing mode.
You need to install the driver package from this page: https://www.dc-unlocker.com/how-to-read-huawei-bootloader-unlock-code
After the bootloader was unlocked, I was able to flash TWRP (the chinese version for the X2) and an english language pack (just place the ui.zip in TWRP -> theme folder on the tablet) - SuperSU worked as well, I'm having some trouble with xposed, sometimes it is working, sometimes it's not.

does resetting phone change the unlock code?

i am trying to lock the bootloader again with my unlock code and it keeps saying the code is wrong, and it worked fine for unlocking.
my question is does the code change after a reset? i completely reset the phone to stock with stock loader,ercovery/recovery just cant seen to be able to relock the device.

I don't think it is supposed to have changed. At least it hasn't before.
fastboot oem relock *code_here*
what do you mean "stock loader"?
but if code is not working , it seems safe to say if you do lock it, and it will not work to unlock again......, if needed.
EDIT: god im stupid... this was the code they sent me: https://i.imgur.com/Zz2VgQz.png
so i was putting in 64ZR9670112GJ3F8 the code is supposed to be 64ZR96701I2GJ3F8
so lesson learned. make sure you really look at the code one's can look like i's in a pic.
