701L flashing just kernel - Huawei MediaPad X2

Hello.
I'm planning to get MediaPad X2 (701L version). I'm going to use it as a car media center - and for this reason I will need to rebuild the kernel (with CONFIG_SND_USB and CONFIG_SND_USB_AUDIO set to support my PCM2704 DAC). I don't care about system updates with 703L ROMs, especially that they seem to cause some trouble. So, my questions are: is it possible to flash just rebuilt kernel, not whole OS, and if it is, what I will need to do with the device first (unlock bootloader, root, flash TWRP)? Will it be possible (in case of RMA) to restore device to factory state?

I never got usb audio working on 701. I am on b211.

Have you tried rebuilding the kernel?

Have you checked GEM-701L.LL.EMUI3.0.opensource.rar from official Huawei support site? Looks like sources to me, but i'm no expert .

Same to me. But even if I we're, I have no idea what to do.
I have one usb device: zoom h4n, which should work, but if even does not work on my nexus 6p. Maybe you could be successful trying your device.

I tried the rom. I flashed my X2 to 703L so I can only fastboot flash this rom. No way to do a full dload.
Anyway, It works fine and smoothly for my X2, but my X2 is originally TW version and this is for TW X2, so it's supposed to working fine and smoothly.
I think hardware wise, there aren't any different in TW or other version of the Gem-702L version. Correct me if I'm wrong
Hmm! Maybe I'll make a stock rooted debloated version of this

Hey, wow I appreciate this very much.
I Converted from 702 to 703 will there be a way to go back to 702L?
If u make a stock debloatet, can u make one without huawei and google stuff as well??
A pure Rom without any supplementary Sniffing Data Stuff would be absolutely phantastic.
Nevertheless, If u d'ont, u do not, Hell on wheels, that's ok for me as well.
Thx, Ray

That would be extremely appreciated if you can do that. I'll try then to see if it converts my 702L with 703L rom back to its original form.
Huawei's TW stock rom is with gapps already, and less Huawei apps. It's basically for international use, only with a regional name.
It will take less trouble than doing a CN stock rom

It was downloading last night but Huawei's site is painfully show. When it said it was going to take 4 hours to download I just left the computer on and went to sleep.
So there's no one that have manually installed this Beta 6.0 on the original 702L ?,

A lot of Taiwanese users have upgraded. The feedback is nice. I don't know about other regions.
I couldn't try it because My X2 has been converted to 703L. It just won't let me get through the dloading.
======
By the way, I don't know if this is useful, but Huawei Taiwan actually provides a downgrade pack for 702L users to downgrade to 5.0 if they are not satisfied with android 6.0
Here's the download link:
http://download-c.huawei.com/download/downloadCenter?downloadId=81363&version=323452&siteCode=tw
It's only 1x kbs, really tiny pack. It says that dload the downgrade pack first then do the full B005(5.0) dload.
Here's Huawei Taiwan download page if you want to download other versions of stock roms:
http://consumer.huawei.com/tw/tablets/support/downloads/mediapad-x2-tw.htm
Anyone who wants to try might go ahead.
I've already downloaded both package, but unsure about wether I should upgrade or not.
Just read on http://www.mobile01.com/topicdetail.php?f=629&t=4812210 , on that the phone is laggy for some and it runs "hot".
All gem702L runs version b006 as latest, while the Taiwan version only has b005 as their latest.
@iamhcg You write yesterday the downgrade script will also convert your 702to703device back to original 702.
Even if it goes hot, you would have enough time to be able to do the dload method to that B201 version.
Are there any advantages to use a version 201 instead 211? Only the strange thing with miracast. Maybe they bugged this after 201. Is there a difference if you go via this version here?

For what I see, the udate.app in downgrade pack contains some img files you can't flash through fastboot, such as crc.img curver.img, etc; those img files are for android 5.0 formaton.. It is a the first step of downgrading your device, then the full dload do the job.
The only thing is that the downgrade pack is for gem-702L. That's why I need to fastboot flash system img files of 702L to make it temporary go back to 702L, hence get the full process done.

The version No. in different regions are not equivalent. Huawei normally develops CN version first, then they make a few adjustment and roll out to different regions. So I'll say B201 TW is very close, if not equal, to B209 or B211.
For advantages, I do contact local Huawei guys, the response is: for regional roms, they make some adjustment to be more suited to the local environment, such as GPS tuning and some stuff. So now that gem-702L B201 is out, they suggest me to flash back.
Besides the official story, my personal experience is that B201 is more compatible to my gem-702l.
China is a huge but closed market. They setup their roms for local use (Hence, no Google services). But they put everything back to TW/International Roms. I think that's why miracast or other stuff runs well on my 702L in B201.
What I feel now:
1. no a lot of useless CN or Huawei apps.
2. complete gapps.
3. Miracast works.
4. Back to warranty of course.
5. stable.
It's basically just close to the user experience of B209 or B211 for 703L users. I am quite satisfied with it.
I think I'll stay in B201 unless the development gap between 702L and 703L becomes huge again, then I'll consider switch between models.
Now there's a safe way to get back, it wouldn't be a problem.
Thank you for this additional informations.
What do you think about the 701 users who had converted to 703 and want to downgrade for some reason.
Maybe someday Huawei could offer a 6.0 for 701 with fixed gps. I really saw an inaccuracy of 10-30 m on only gps using offroad usage and don't know if this is a consequence of my conversion to 703)
I think it could be possible
- flashing the four 702 img files,
and the universal cust b112,
Then it might be possible to use the downgrade script for 701 model, too.
Then I would install universal cust again and dload the B003 firmware for the 701.
Any comments about this idea?
My device: 701->703 Kang VIP B209
Ok.. I've finally decide to update my Gem 702L to this Android 6.0, and so far this is my review of this update.
Everything run smooths.
There aren't as many shortcuts in the pulldown menu as before.
DPI changer is a nice thing, otherwise there aren't many changes.

**sorry I have to edit my own post a bit:**
I am not a developer so I don't even know what the uiversal cust does. You probably know more than I do.
I only know there are 2 quiteria:
1. you have to cheat the downgrade script that your device is a 702L for the downgrade to work.
2. You'll need a 701L-cust zip when you want to convert back to 701L
I don't know if unversal cust does the job. If yes, then there's no problem. If no, I rememeber ZeuseZ made a 701 cust file here: http://forum.xda-developers.com/showpost.php?p=66824282&postcount=62
I think "Channel_ru.zip" is a 701 cust in Android 5.0 but I am not sure. Maybe you want to check with him.
Once you have the proper 701L flashable cust, I suggest you to follow my steps, first to make sure you can downgrade to android 5.0 as a 702L. The downgrade pack will check if your device is a 702L. If it's not, the downgrade/dload will stop.
Once the downgrading is done, it is easier from here.
You can simply extract img files from stock 701L, fastboot flash them, format internal storage, flash the 701l cust, then do the full dload thing. Then you should be back to 701L stock.
Yes I see. I doubted zeusez script would do the downgrade. Now we know that this is indeed only a partial of the process.
It just sets the system to a cust folder for region ru and offers that file.
I would need 'eu' for Europe.
I got that original eu file from a user with a untouched 701.
But it could be sufficient to set the model number and temporary to ru, so that dload for the B003 for 701 EU would work on the next step.
I will not test that personally until HW would offer a 701 upgrade. But I am sure there will be users who want to revert their phone for other reasons.

I've posted my process here. It's actually easy. You just have to go back to full B112 stock first; then follow the instructions. Where you are now is pretty much where I started.

Mate 9, cannot get bootloader unlock code from Huawei

Guys, I have an MHA-AL00 that I get an error on Huawei's unlock site:
https://emui.huawei.com/en/plugin/unlock/detail
"The Huawei ID used to apply for the unlock code has not been used on the device for more than 14 days."
I emailed support in the US but they sent a form letter stating they do not EVER provide unlock codes.
Any advice on how I can get this thing unlocked??
Wait 14 days or get bootloader code via dc-unlocker (it costs a few euro. I guess it is 4 EUR)
https://www.dc-unlocker.com/downloads
Watch the tutorial video there. Do not press 'unlock' button, but 'get bootloader code' button.

OK, I guess I'll wait, but do you think that message is confusing enough?? Did you get yours after 14 days, anyone else successful??

I'm reading that error message differently -- waiting isn't going to help you. The problem is that you haven't logged into the HiCloud or HiApp services (or anything else using a Huawei ID) in the last two weeks. Re-enable those apps if you have them disabled, log in, then request your unlock code.
The 14 days waiting is only for chinese models. AL00

Send an email to mobile AT mail01 Dot huawei Dot com, including the following information:
1. Dial *#*#2846579#*#*, ->Version Info->Other Info, make a screenshot
2. Your MEID, IMEI number.
3. The screenshots of failed unlock (including 2 IMEI and MEID).
Then ask them to give you the unlock code. You will get it in 2 days.
Good luck.

IMEI still 'null' after using FunkyHuawei to restore...

Hey guys, I'm desperate with this device... I never had so much troubles with a single android device before and I don't know what to do anymore.
I tried to restore my device via the offline-method, while this didn't work out And between these tries, I've lost my IMEI. After various other tries to restore it, I thought I could try FunkyHuawei to restore. It all showed up as it should and worked well. But the Mate 9 still wants a Certain Unlock Code for the SIM-Card and still shows up IMEI null ( 0000000000000 ). Is there anybody, who has an idea, how to fix this ****ty phone? I need to get it work, because I have to send in my S8+ because I broke my display..
EDIT: Bootloader shows PHONE Locked and FRP Unlock... if that helps? ><
Desperate greetings and thanks in advance,
Ardian

How to root Honor 6X BLN-L21?

Guys i want to root my device - Honor 6X BLN-L21. how can i do this?
after rooting my device ill be able to update my software ? i have the latest android 7 official update from huawei installed. i havent unlock the bootloader or anything like that.
thank you and soory for my english.
Follow this guide https://forum.xda-developers.com/honor-6x/how-to/root-huawei-honor-6x-install-twrp-t3671822
And for obtain your bootloader unlock code, note that the listed procedure is impossible to follow at the moment, because the necessary pages to ask for the code are unavailable on Huawei sites. But you should be able to have a work around thanks to the module available here https://forum.xda-developers.com/ho...cial-request-bootloader-unlock-codes-t3785100
I am resurrecting this thread as I have the **same** issue a year after.
I have recently aquired a BLN-L21 Honor 6x europe, with EMUI 5.0.3
This is the exact ROM version: BLN-L21C432B382
It has been rooted using dc-unlocker, but now I have some problems with rooting (that was my entire objective since start)
Compatible TWRP are scarce, I can only make it work with OpenKirin TWRP 3.1.1.0, linked in the guide above, or EliteTWRP-3.2.1.0, but this one cannot read any internal partitions, so I guess it's not very useful.
As soon as I flash Magisk-19.3.zip the device boots and asks me for a decryption password, that I clearly don't have.
So Flashing Magisk this way makes the terminal useless.
Can anyone suggest me a couple of TWRP + ROM that supports root quite well on this device?
EDIT: ouch, I defeated myself. I just tried to use SuperSU-v.2.82-201705271822 and it works like a charm on stock rom.
I wonder why Magisk makes a mess of the partition

What OS for Mediapad T5?

Hello guys,
I made a big mistake - I bought the Mediapad T5 in the 16GB 2 GB Ram version because I thought this is enough - however, it turns out that their EMUI occupies already 1.6 GB of RAM and therefore, even the keyboard crashes, lots of jerks when playing a video in HD, apps crash it is really a mess;
So the only idea I had (although I am not too familiar with custom ROMS) to replace EMUI by some system which does not occupy too much RAM; So I first was frustrated that the bootloader is naturally locked but I found a solution by downgrading the system and then unlock the bootlader with DC unlocker for around 4$;
Now I think I need to do the following steps:
1. Install TWRP
2. Flash a new OS
3. use TWRP to install a patch called the "low-ram property patcher", see here: https://forum.xda-developers.com/an...mod-low-ram-property-patcher-android-t3737373
Now in theory it seems easy; TWRP is naturally compatible to my device, right? So I can probably find many explanations how to get it; But then I need to find a new OS compatible for my device which is a problem; I want an OS compatible to my device with not too high RAM consumption; I thought of Lineage 15.1 but only the Mediapad M5, not the Mediapad T5 is supported; So anyone an idea what OS I can choose?
Many thanks

Hi everyone.
I have a Huawei mediapad T5 AGS2-L09. It has 2 GB RAM and 16 GB internal memory.
I updated the software and a new option in the developers optons emerged:
"OEM Unlocking" - Allow the bootloader to be unlocked
When I turn it on a dialog box pops up with a warning:
"WARNING: Device protection features will not work on this device if this setting is enabled."
You have the option to CANCEL or ENABLE.
This is it, right?
Does anyone know how to root it from here and hopefully has a custom ROM?
The build number: AGS2-L09 8.0.0.222(OCEC432)
Android security patch: September 5, 2019
This option may or may not help. On Xiaomi devices the bootloader can only be unlocked by Xiaomi. The option you see in do is not made by Lenovo I think, it is an Android option. Please check it and try to install TWRP. Afaik Huawei does not allow unlocking...
PLEASE MAKE SURE TO USE ONLY TWRP THAT IS PROOVEN TO WORK WITH YOUR DEVICE!!!!

Hello,
I just bought this tab ( 3gb version), but i don't understand why there is no custom rom on this Tab. No LineageOS for exemple ?
So sad
Why ??

Because it's Huawei, they don't want your device unlocked and replaced with unsanctioned software so you can remove the Chinese government spyware
