This is how I managed to upgrade 7D-501L European 4G model of Mediapad X1 7.0 to kitkat
(this is the X1 model sold by Conrad)

WARNING: This is not for 7D-501U / 7D-503L but only for 7D-501L

Step 1: download HiSuite to your PC
http://www.huawei.com/minisite/HiSuite_en/
and install it on your PC. Connect your PC to your X1 with the USB cable.
When asked by X1 allow USB debug mode.

Step 2: use HiSuite to make a backup of your apps and data
(warning: Note that data from some apps are not included in the backup so you need to back up these other data from these apps to a SD card, also your google account is not back-upped by HiSuite, so you need to synchronize with google servers and set the google account up again after the kitkat upgrade and restore of backup and then re-synchronize)

Step 3: Download the latest kitkat ROM for European 7D-501L model from this German link:
http://huaweidevices.de/mediapad-x1-7?show=downloads
At the time of writing the most recent version is "Software update version B102". Don't worry about not speaking German, the update has a very large amount of languages, including English.

Step 4: Take an empty SD card of at least 2 GB and at most 32 GB. Make sure it is formatted as FAT or FAT32. (note that NTFS and ExFAT formats will not work!)
(On your PC) create a new folder on the empty and correctly formatted SD card named: dload

Step 5 Go to the downloaded zipfile with the kitkat ROM, open it, and locate the file named "update.app" and extract that file.
(in the HUAWEI_MediaPad X1_SDCard_Upgrade_B102.zip it is in the folder /HUAWEI_MediaPad X1_SDCard Upgrade_B102/ but this may be different in versions >B102) The size of the B102 version of the update.app file is 1,515,820 bytes.

Step 6 Copy the extracted update.app file to the dload folder on your SD card.

So you now have an SD card with just one folder named dload and in that folder one file named update.app and nothing else.

Step 7 Make sure your X1 has enough power to complete the update. To be sure, connect it to the power adapter.

Insert the SD card in your X1 and reboot.
Wait and be patient while android runs its update app and outputs all kinds of comments on what it is doing to your screen.
Just leave the X1 untouched during this update process until it is ready and shows a big OK on the screen.
At that point it will ask you in small font to remove the SD card and reboot.

IMPORTANT: If you want to use the SAME SD card in the X1 for extra storage, make sure to delete the update.app file before reinserting the SD card in your X1.

After reboot, in the welcome screen scroll to select the preferred language BEFORE you press start, and follow the instructions that follow to re-setup your X1.

Go to Settings, About Phone to check your Android version number and Build number.

After your account etc. has been re-set up you can restore the backup of your apps and data using HiSuite (and next you can re-synchronize with google servers if you use them)

If you don't like the 400DPI problem of this kitkat implementation for X1, you can revert to the 4.2.2 Android 320 DPI version using the B006 rom available here:
http://consumer.huawei.com/download/...mp;siteCode=tw
After installing that B006 ROM, the X1 initially will only speaks Chinese or English, don't worry: after going to settings, updates,system updates, online update, it will upgrade from B006 to B007 (7D-501LV100R001C324B007) and provide much more languages to choose from.

I hope this is of help.

Thank you. Strange user shah6630 said : "but on network mode theres only 2g only no more 3g only" ??
Anyway I think I had a bad download. The download took nearly 4 hours lastnite and was probably bad.  It fail to install and I only see continous Huawei splashscreen logo ( did a manual update and switch off phone restart too) . Tested on 2 other ext SDcards - similar scenario too
The zip file however extracted well - no issues
Will download again

Dear sir,
your problem is mine at 100%
Exactly the very same similar issue on mine
BUT I am an old man and newbie
my email is bvannier@famille.im
Kindly yours

HI Beny 888 and other
you can extract the recovery.img from an update.app with the "Huawei update extractor" search on google.
ive the same issue i extract the recovery from the B007 and flash with fastboot (flashify dont work)  and all its done
the fastboot command is:  fastboot flash recovery recovery.img

the link to the official xda thread http://forum.xda-developers.com/showthread.php?t=2433454

you can also extract .IMG than you want , modify it with android image kitchen
http://forum.xda-developers.com/showthread.php?t=2073775
,flash .img with fastboot look for command or a fastboot/adb gui to google or repack the entire firmware with huaweii update extractor for a full flash

i tried to modify boot.img but it seems the .header of certains files is separate and i cant extract those files so cant modify kernel for gpu oc or add frequencies or gouv if somebody have an idea

I have updated last time to R002.... B102. Why are we downgrading to R002.....B007. My last update was from the German rom and this B007 is from the Taiwan website. Somebody please clarify.

Malaysia Huawei has released a firmware update

7D-501LV100R002C209B008
http://consumer.huawei.com/my/tablets/supp...iapad-x1-my.htm
Kitkat Version??

I Believe Malaysia release the Firmware is because my e-mail to their Richard Yu, CEO of Huawei Consumer Business Group

Below is my e-mail to him on MOnday

Dear Mr Richard Yu,
Good day to you, I'm a very disappointed MedaiPad X1 user from Malaysia.
I must tell you that, the Mediapad X1 indeed a very good design product, unfortunately there was no Firmware update for International Version 7D-501L to settle the bug.

I do understand there was many firmware update released for Chinese Version such as 7D-501u and 7D-503L.

as a Global top 50 companies, if you not ready for International market and yet only focus on China market then please don't sell the product such as MediaPad X1 outside China!

One more things is that, and I'm sure you won't know about it. Your Malaysia Huawei FB is suck! those people there is sleeping and is great cheater!
they always tell us the firmware is coming...but, after waiting for more than TWO months the firmware ready is never happened!!!

after post many message on your Malaysia Huawei Facebook and we never get any reply!

I hope Mr Richard you yourself go and read the messages post at the Malaysia Huawei Device MY check out your self how BAD is your Huawei FB!

Mr, Richard Yu, I'm so sorry to write you this post over here, but I have no choice because non of your Huawei staff do care about me and others disappointed customer!

Mr. Richard Yu, if still no new Firmware update release before 26 Sep 2014.
I hope you instruct your Malaysia Huawei staff to refund me my money in FULL and I'm not willing to wait any longer.

my contact is chinkc01@gmail.com and my HP no is +6013-32XXXXX

Good evening,
With rootexplorer,I can modify easily the properties of any files inside my internal X1, but I have been trying to get a file only readable on my Extsdcard. I can't do it because "you don't have the autorisations to modify on extsdcard.
Any ideas folks?
Think you very much
Kindly yours from an old man
