I come from many years using and flashing Samsung phones. This is the first time I have a Huawei phone and this is all new territory for me and very worried to do something wrong. Could not some give me a very quick overview of what steps are needed to get bootloader properly unlocked to start with?

I bought my 702L a couple days ago. Have done nothing to it yet. I'm still on a B003 ancient build and getting several notifications to update but I haven't because I don't know if I should first to the unlocking and rotting with that it is, or with what updated Android 5.x build.

To start off, the instructions on the first post of this thread seem wrong as when I go to http://www.emui.com/plugin.php?id=unlock&mod=detail I'm greeted with a jump page (also all in Chinese) that instantly takes me to the main EMUI portal, or eventually to a error message page:

emui.huawei.com/huawei/static/html/600.html

By the way, I successfully created a user name and password for the site but till cannot access the page related to inputting the phone's information to request the unlock code..

I will go with the DC Software Unlocker option because seems the email option requesting the unlock code is also a big waste of time as I don't read about ONE SINGLE PERSON that has ever gotten a reply from Huawei.. typical..

Anyway, getting my around the DC Unlocking Software to get the unlock code, I think I can manage, but the next steps, I am a bit gush out of the water:)

Before I even put my phone in bootloader mode and connect it to the computer, I assume I need some sort of drivers package from Huawei (like I also got for each Samsung device I've had in order to flash them). What are these drivers from Huawei and where to get them? Next, I never used fastboot and seems daunting. Is this like a terminal? Can I use a minimal fastboot install package or I also need install the full Android SDK/ADB stuff that is a nightmare?.. I tried it a couple of times with Sony phones before and everything went wrong for me. I gave up all Sony phones since then specifically because of the insanely complex procedures just to get the bootloaders unlocked and the phone rooted. Now I realize I'm back at having to use the same set of apps that I failed on miserably in the past. Maybe I'll be more lucky this time:)

So, finally when (if) i get all to be running and phone/computer/fastboot all talking to each other, what exactly will I need to be typing and where? The first post mentions to type the oem unlock xxxxxxxxxxxxxxxx where will be my bootloader unlock code, but I have no idea what I'll be doing because site never done it.

If someone could explain this to me or get me some screenshot I'd be super appreciated. I'm very worried I'll brick or kill my lovely new x2 at my first attempt to tweak it!

Thanks again:)

First do the update that keeps coming up. I have experience with all brands of Android phones. Fastboot is the easiest and can be even easier then using Odin. Then use DC Unlocker to unlock the bootloader. Then you need to download android platform tools first then download the rom you want to fastboot flash. (see eenapps thread for that) Then download Huawei Update Extractor to extract the actual img files you need to flash (boot, cust, cache, system userdata) Then put those img files into your platform tools folder and open a command prompt to the platform tools folder and one by one type in fastboot flash boot boot.img then fastboot flash cache cache.img, fastboot flash cust cust.img, fastboot flash system system.img, fastboot flash userdata userdata.img

After this type in fastboot reboot to reboot the phone. It should boot up into Android. After it does you go into settings and do a factory reset and choose erase internal storage or else it will only see it as something like 7gb instead of the full amount. Then take that same rom you downloaded (the one you fastboot flashed) and make a folder on your internal storage called dload. Take the update.app file from that rom (it should be over 2gb) and put it in the dload folder. Then go into settings /updater and hit the three lines at the bottom and choose local update and it should find it then hit update. Do this for each rom you're upgrading to (B015,B106, B109, B111)
[Huawei MediaPad X2] VeEuzUKY:
First of all thanks VERY MUCH for the detailed information, ajsmsg78.

Wow, overwhelming, I'm crushed!? I have a few pending questions:

- The update that keeps coming you recommend that I first do is the B003 to B006 OTA, correct?

- Next, to begin using fastboot, I first need to install some sort of Huawei software USB drivers so the computer can recognize and communicate with the phone thru the USB port, correct? What drivers are these and where do I get them?

- The Android Platform Tools you mentioned I'll need, I assume I need them already installed on my computer before I can unlock the bootloader with the unlock code I'll get from the DC software app, correct? Will a minimal fastboot setup be enough or I'll need the whole Android SDK Suite? Before, when I tried play with Sony Ericsson phones, I realised a minimal fastboot install was all needed to make make fastboot work properly without the full Android SDK Suite that was an overkill and nightmare to ever get properly configured and working.

- Once I have unlocked the bootloader, I should install a recovery and root the current stock ROM first prior to do anything else, correct?

- Finally,regarding the intricate procedures you mention to later update to custom ROMs by extracting the IMG files and flashing them one by one.. can't that simply be done by using the recovery to flash a ZIP/ flashable format of the new ROM?.. or that is just for Samsung stuff that I am used to?

Super awed at this whole process all new to me. Thanks a lot again for your help and expert guidance on this:)
[Huawei MediaPad X2] ajsmsg78:
When I get home I'll send you links to each one.
[Huawei MediaPad X2] ajsmsg78:
Android Platform Tools. You don't have to install this, just extract it to a folder on your desktop:

https://docviewer.yandex.com/?url=ya-disk-public%3A%2F%2FvI5Y3Obeku4qzIrtHfPviJPL3yhTpSABBi9V4fM0UpU%3D%3A%2Fadb%2Bfastboot%2Fplatform-tools.zip&name=platform-tools.zip&c=568f1d91f927

Huawei Update Extractor. You take the stock ROM (update.app) file and extract the img files from it with this tool. Then you put the 6 img files (listed below) you need to flash in the platform tools folder:

https://docviewer.yandex.com/?url=ya-disk-public%3A%2F%2FvI5Y3Obeku4qzIrtHfPviJPL3yhTpSABBi9V4fM0UpU%3D%3A%2FRomUnpack%2FHuaweiUpdateExtractor.zip&name=HuaweiUpdateExtractor.zip&c=568f1e877bdf

You then open up a command prompt to the Android Platform Tools folder and flash each img by typing in the following:

fastboot flash boot boot.img

fastboot flash cust cust.img

fastboot flash cache cache.img

fastboot flash recovery recovery.img

fastboot flash system system.img

fastboot flash userdata userdata.img

Then hopefully the new ROM boots up. Then go into settings and do a factory reset. This will make your internal storage show the correct space. Then make a folder on your phone's internal storage called dload and put the update.app (from the ROM you downloaded before you used Huawei Update Extractor to extract the img files) inside the dload folder. Then go into settings, updater and at the bottom choose Local Update. The phone will see the update.app file you put on the interneal storage and just select that and hit update. This will flash EVERYTHING from the new ROM on to your phone including the radios etc.. These are the things that Huawei doesn't let you flash in fastboot. Then once this is successful you'll officially be converted to a 703L. Now you should be able to do 703L OTA's .
[Huawei MediaPad X2] VeEuzUKY:
Thanks so much for all the info. Very much appreciate it. Let me do these things one by one and see how far I can go. I didn't know before the plan is to convert my 702L to a 703L. I thought they are almost the same units for all practical manners. I try to do some research and cannot really find out the differences between the two models. I guess just radio frequencies? I'm in Hong Kong (I'm from Los Angeles but here for very long time working).. so don't know if the 702L is in fact maybe more suitable in the region for me or not. Here they only sell the 702L, no other model. What do you think about this or what would be the practical benefits to convert to the 703L version?

Thanks again for all info and links!
[Huawei MediaPad X2] audioralf:
I have described this as list with all links at eenaps thread.

http://xdaforums.com/showpost.php?p=64623653&postcount=378

I have extracted the 5 files from version B015, so you will not need to install Huawai Update Extractor.

It seems to be ok just do the fastboot flash the 5 files for B015 and then the factory reset with format of SD.

Then you can do one dload after another. This maybe faster than waiting for the OTAs.
[Huawei MediaPad X2] ajsmsg78:
Yep, you are correct. The key is after each fastboot flash and factory reset that you do the dload method afterwards to get everything else updated. This will update the bootloader radio zdiffer, etc. The dload method will NOT fail or at least it didn't fail for me on my 702L after I flashed the proper cust for the rom I was currently on.
[Huawei MediaPad X2] rakesh_4utoo:
I am new to x2 and having model 702L but while providing all details while unlocking on official site i am getting message that i should be login into device with Huawei id for 14 days.

But on my device i couldn't find where to login my Huawei id.

Pls help
[Huawei MediaPad X2] omniphil:
I tried that DC Unlocker site and paid the 4 credits. Software runs fine but I end up with 4 unlock codes. NCK, NetSub, SP, and Unblock.

I tried fastboot oem unlock xxxxxxxxx with all 4 codes and they all come back with wrong password?

If I do fastboot devices, it sees the device fine. I can even run fastboot reboot-bootloader so the phone is responding, just doesn't like the codes I got..

Which of the 4 codes did you guys use that tried this method?
[Huawei MediaPad X2] ajsmsg78:
When you went to unlock did you choose Read Bootloader Code? If you didn't you're gonna have to buy another 4 credits and make sure you choose Read Bootloader Code.
[Huawei MediaPad X2] audioralf:
You were pressing the wrong button in dc-unlocker. Read bootloader code is the correct one.

Ralf via Tapatalk. GEM701L, B111Kangvip Rom
[Huawei MediaPad X2] omniphil:
Huh, ok. So read unlock code was what the instructions said to do.... I'll try again with read bootloader code
[Huawei MediaPad X2] audioralf:
Well this is a trap. On page 1 in OP you find the instruction 'get bootloader code'. And the fast boot command is unlock.

So this is confusing. The button 'get unlock code' is made for unlocking SIM.

Ralf via Tapatalk. GEM701L, B111Kangvip Rom
[Huawei MediaPad X2] omniphil:
Yup, read bootloader worked!

Thanks guys!
[Huawei MediaPad X2] ajsmsg78:
I edited the instructions slightly to make it easier to understand.
[Huawei MediaPad X2] audioralf:
Just for all who want to go back to the firmware which was on the device when you bought it.

Clarice has found the long updade for the for our Mediapad X2

It is not the expected update to B106, but the [https://drive.google.com/file/d/0By1mhgPLc1LqbnpXTVhWU3RSYVU/view?usp=sharing]original B003[/URL] firmware.

Maybe it could be useful, if someone founds that LTE Band 20 (LTE 800) does not work anymore (I know no one !)

In this case we could put the baseband related images into the dload for the B111 stock. (But this is a just theoretical item)
[Huawei MediaPad X2] jytprf:
in the dc-unlocker forum were giving unlock bootloader codes for free to huawei phones, now those forums are closed...
[Huawei MediaPad X2] karl1234:
hi all. here is where i am, i have put in the code and it said unlock. but he phone in fast boot mode. and it came up unlock. Someone told that the phone bootloader is unlock. i put the code in again and it said that it is already fastboot unlocked. so I unlocked the bootloader or the fastboot loader. are they not the same thing. if i have unlock what next. i really want to root this phone.

thanks
[Huawei MediaPad X2] audioralf:
Fastboot is a word for the application which can send commandos to the phone and transfer data like a new recoveryprogramm (TWRP)

This is what you can do now after unlocking bootloader. Follow the guide how to flash the 5.0 TWRP, and in TWRP install supersu. After this you are save rooted.

Unlock bootloader

Just to let you know I used option 2 and got my unlock code instantly on the Huawei page! Perhaps they changed their policy about the two weeks, or it's because I've an 701L, I don't know.

So don't be "afraid" of option 2, just give it a try :)

Thanks to this forum I'm unlocked and rooted, now thinking about going to install a 703 rom.
[Huawei MediaPad X2] karl1234:
so have i unlocking bootloader.or do i still need to do something else. or can i move on to lash the 5.0 TWRP, and in TWRP install supersu.
[Huawei MediaPad X2] karl1234:
still not sure that i have unlocked bootloader. but i move onto the next step. i downed twrp eng 5.0 and twrp eng 5.1. put the phone in fast boot most then upoad file via cmd with fastboot flash recovery twrp_cn.img. the cmd said send recovery . it did took a few second then finished and then writing recovery. then done. .i was expecting my phone to turn off and reboot or see my phone do anything. nothing happen so . turn the phone on. see if the phone was able to be rooted and nothing. i then turn the phone off again. started it up with volume up and power. but got the startard recovery message. no sure what i am doing wrong. or i am dont have the bootloader done or i am just missing. ok thanks
[Huawei MediaPad X2] ajsmsg78:
If you plug the phone into the computer and hold in power + volume down to boot into Bootloader Mode and it says in red Phone Unlocked then you are unlocked.
[Huawei MediaPad X2] karl1234:
yes i can put it in fastboot mode. by pluging the phone into the computer and hold in power + volume down to boot into fast boot Mode and it says in red Phone Unlocked then you are unlocked. So my phone sayes unlocks. ok so what are the other problem that i haven't with the i downed twrp eng 5.0 and twrp eng 5.1. put the phone in fast boot most then upoad file via cmd with fastboot flash recovery twrp_cn.img. the cmd said send recovery . it did took a few second then finished and then writing recovery. then done. .i was expecting my phone to turn off and reboot or see my phone do anything. nothing happen so . turn the phone on. see if the phone was able to be rooted and nothing. i then turn the phone off again. started it up with volume up and power. but got the startard recovery message. no sure what i am doing wrong. or i am dont have the bootloader done or i am just missing. ok thanks
[Huawei MediaPad X2] audioralf:
Pull out the usb cable iff you want to boot into TWRP.

Why should the phone reboot after you have flashed something? There are situations, where you will need to flash more than one file.

You could reboot via command: fastboot reboot

Then quickly unplug usb and press power abd Vol up. If you have 4 hands you will be able to proceed this. I don't. So I unplug, and then press the keys.

[Huawei MediaPad X2] xdvsr:
Even when trying to flash TWRP it says:

"FAILED (remote: image verification error)"

(nb: bootloader is unloacked, it says in red: phone unlocked)

What is the best way forward from here to root this 702L ?
[Huawei MediaPad X2] audioralf:

I get the same error message for TWRP as when I try SuperSu images for the "fastboot+SuperSu" procedure (correct B-version provided).

What could be the reason, what should I test?
[Huawei MediaPad X2] audioralf:
You must install supersu via the correct TWRP
[Huawei MediaPad X2] xdvsr:
It is now stuck in a bootloop, but not the "fastboot & rescue mode", but the worse kind,

"rescue mode" only. Neither stock rom on microSD in /dload nor vol & power combinations seem to help, and fastboot is not available... :eek: :confused:

What can help here? Any help much appreciated ;)
[Huawei MediaPad X2] audioralf:
To start TWRP you must unplug usb.

What was the exact command you typed on adb console?

#

To get a fresh start I erased with fastboot all img of

boot, cache, cust, recovery, system, userdata

and then was stuck in the bootloop, out of which I got with usb cable plugged in and then the vol/pwr button combinations (without the usb cable in it would not go anywhere and stay with the errors on screen: rescue mode...pls update sys again...user guide...zh.ui.vmall...error!...Func NO: 10 (boot image)...Error NO: 1 (security verify failed))

#

Then tried to have another update.app of B012 read in, but it did not work. Same for stock B106 which was on it before (stopped at 90%, twice).

#

Now in fastboot/rescue, all original B106 img were flashed OK, except system.img:

fastboot flash system i:\system.img

load_file: could not allocate -1976481844 bytes

error: cannot load 'i:\system.img'

#

Then tried via microSD, but am not sure if it can read it at all:

fastboot update /mnt/sdcard1/dload/update.app

error: failed to load '/mnt/sdcard1/dload/update.app'

fastboot flash system /mnt/sdcard1/system.img

error: cannot load '/mnt/sdcard1/system.img'

fastboot flash boot /mnt/sdcard1/boot.img

error: cannot load '/mnt/sdcard1/boot.img'

fastboot flash boot /dev/sdcard1/boot.img

error: cannot load '/dev/sdcard1/boot.img'

As you can see, dev or mnt, same error, perhaps it cannot even get to it, yet it said also failed. Not sure what to make of this.

-----Any help to get this working again, and most importantly root it, will be much appreciated :)
[Huawei MediaPad X2] audioralf:
Who told you to delete the bootloader?

You must flash the files of the version you were last on. Then you could try dload form ext sd via power vol up and vol down. If something appears on screen release power key and keep holding the vol keys until dload starts.

It may be in Chinese, but with 2 buttons. Try which button will start dload.

Your commands are false. Fastboot refers to a file which is on your pc adb directory. The adb window is no terminal.

Put the TWRP and the other files inside the adb directory on pc.

Open a cmd window on this path and you will be able to use the commands without path.

Put update.app inside a folder dload on sd card and try to start dload like described. If system starts, you can flash TWRP for 5.0 as substitute for the normal recovery. If it does start try TWRP for 5.11

[Huawei MediaPad X2] ajsmsg78:
On your second # that is where you made the mistake. Before you did the volume up volume down and power to do the dload you needed to flash TWRP then the cust mod first to get your phone on the proper cust folder. Then you flash back the stock recovery.img. Then it wouldn't have failed at 90%. Even if it failed you should have still been partially updated to b106, then you could just flash the cust mod after it booted (if it booted)
[Huawei MediaPad X2] xdvsr:
As from the other post, I cannot get any twrp flashed, all the same error re verification. Until that is fixed, no cust mod, no root, no file recovery, no usage...
[Huawei MediaPad X2] ajsmsg78:
The only other thing I can tell you is if you wanna ship me the phone i'll try and fix it and ship it back to you, if not you may have to send it back to where you bought it from.
[Huawei MediaPad X2] xdvsr:
Many thanks, I strongly consider this, especially if I cannot get it done myself shortly, and if the seller does not fix (but I should get a new one, as this one was obviously not factory standard w/ 703L B005 on 702L and bootloader unlocked, not updating at all).
[Huawei MediaPad X2] xdvsr:
As trying to flash certain images, begets this error message:

"FAILED (remote: image verification error)" a search suggested, it might be a bootloader still locked.

What else could be the reason for such an error (provided other images flash fine and the files are not corrupt)? Is it possible that some images for say 'recovery' or 'boot' flash fine, and others not?

I thought my bootloader was unlocked, as dc-unlocker and Alkalinorap showed it so.

No the comand is

Yes, sorry, that's what i meant. fastboot oem unlock xxxxxxxxxxxxxx where x is your bootloader unlock code. You need your unlock code to verify that you're actually unlocked.
