How to get DUAL SIM SELECTION 3/4G working on 702L after flashing 703 ROMs

UPDATE (on 28 Nov 2015)
====================
Updated thread by "ajsmsg78" on B110 ROM from 703L that can be flashed onto your 702L model plus the benefit of Dual SIM selection preserved, rooted with superSu, Google Play and Contacts sync included. Please go to:
http://forum.xda-developers.com/mediapad-x2/development/rom-stock-b106-gapps-t3230585
UPDATE (on 22 Nov 2015)
====================
Thanks to "ajsmsg78" for detailed explanation and posting flashable ROMs to achieve this for 702L owners like me. Please go to:
http://forum.xda-developers.com/mediapad-x2/development/mod-sim-card-switching-fix-t3254534
INITIAL POST
==========
Firstly please follow the guide on how to flash 703L ROMs onto your 702L here:
http://forum.xda-developers.com/mediapad-x2/general/how-to-flash-rom-x2-gem-703l-gem-702l-t3228915
After flashing your "About Device" will show mostly wrong info but the next step below will rectify it.
After rebooting and ensuring the 703L ROM is running fine on your 702L, go into BOOTLOADER mode and do:
"fastboot flash cust CUST.img" ---- the "CUST.img is extracted from your stock B003 (702L) UPDATE.APP ROM file.
For example I flashed stock B106 onto my 702L and then rooted it and installed Kang_5.1.1_twrp as well so that I can make backup of my phone whenever I flash anything new. The "About Device" will show that it's a B106 but the Android version will show 4.3 and EMUI 2.0 etc mostly wrong info. Also the Dual SIM selection of 3/4G will not be working anymore.
After I flashed the CUST.img from the stock B003, not only the "About Device" show the right info indicating Android 5.1.1 and EMUI 3.1 (the build info will show B003 but it's ok) now I got back my Dual SIM selection of 3/4G !!!

Great post. So you flashed the cust from your stock 702L ROM and everything is working. Any time you flash a new ROM that also flashes a new cust folder just fastboot flash your original cust folder and that should fix it I'm assuming.

Very likely this is the case - will try with B109 or B110 next time. Will observe my B106 for a week but so far working fine !

Ok saw it......will try tonight once I reach home (it's day right now my time zone)

I wanted to give this a try too but somehow I can't flash the CUST.img file ("cannot load CUST.img"). Would you mind sharing just the CUST.img file you used?
*Finally got it to flash. Stupid user error..
Thanks a lot for sharing the information, I can finally get dual SIM selection + carrier aggregation back!!!
**After some further testing, it seems the notification problem with the 702L is back. I.e. notifications aren't sent to android wear devices. (This bug was fixed in the later updates for the 703L hence why I decided to flash to 703L ROM in the first place)

I've no issue with notifications working with my Huawei Watch from my 702L ?
I used to have notification dropping issues B003 stock Android 5.0.5 but ever since I flashed 703 stock B106 which is Android 5.1.1 I never had the problem anymore.
Even after the Dual SIM selection now working the notifications working great on either my Sony SmartBand SWR30 as well as the Android Wear Huawei Watch.

I'll give it another go, factory reset the watch this time and uninstall / reinstall android wear
Btw, is multi-window working for you?

Thanks. I created a flashable zip to flash it. The thread and download link is here:

When I flash cust.img B003, File multiwindow_whitelist_apps.xml from /data/cust/xml/multiwindow_whitelist_apps.xml is missing.
I can't fix multiwindow for all app.
PS. All file in cust folder (data/cust)​ is missing. I copy cust folder from 109's rom then paste to. It's work but when restart, all file is missing again

After I flashed the CUST.img from 702L B003 / 703L B016 back and forth (I was testing) I suddenly lost the ability to use multi-window with my apps by changing the xml file. I discovered that the "cust" folder was corrupted (it became a file with no extension and flashing over it didn't get it back to normal). I finally deleted the "file" and created a "cust" folder myself and dropped the xml file in the newly created folder (/data/cust/xml/) and cleared cache + data from the HWdualwindowlauncher app and got multi-window working again.

Can I flash this 5.1.1 rom on GEM-702

http://forum.xda-developers.com/mediapad-x2/development/rom-stock-b106-gapps-t3230585
I'm waiting 14 days to unlock my GEM-702
Can I flash this rom without update 5.1.1 first ?
How to update it when I unlock my mediapad?
1. Unlock boot loader
2. Install TWRP Recovery for 5.0
3. Flash the B110 ?
Is the step correct? Or I need to flash the kangVIP first?

So far I've not known of any 702L owners that had successfully moved from B003 to B110 directly. You may try your above 4 steps and see whether it works but between step 2 & 3 please do a full nandroid twrp backup just in case.
My own exprience was from B003 you need to at least go to B106 first before you can flash B109, B110 or anything higher than B106 because it requires twrp 5.1.1 which only works with B106 onwards.
Twrp 5.0 seems to work up till B015 only.
On how to move from B003 to B106 please refer to "eenap" guide:

now my phone on X2-B111_Kangvip

cpu quad core 1.2 ghz
can go back to GEM-701LV100R001C199B001 via dload method.

Just flash the universal Cust, and this will fix the false info "about the phone".
Did you go all the steps which I have described here? http://forum.xda-developers.com/showpost.php?p=64623653&postcount=378
I had tried to jump directly vom B106 to B111KangVIP, but it was not working properly.
If you try to install back the B001 you will perhaps loose the function to charge the battery. So be warned.
And by the way: my 701L had version B003. Are you sure your phone had B001? If yes ok. But if you have fully upgraded to Android 5.1.1 the flash of a lower version could produce unwanted effects.
After some experiments I restarted by flashing the B106 did a factory reset and then installed B109 and B111 stock via dload and then B111KangVIP. Then you will have back the full working machine and you will be happy.

where is the universal Cust ??? my phone had B001 my ask can i back the B001 or cant

You find univeral cust here: https://drive.google.com/file/d/0B5I_q70mNuR4VFhMc21DNGYtMHc/view?usp=sharing
You must flash it via 5.1.1 TWRP https://drive.google.com/file/d/0B5I_q70mNuR4Uy1XdXVoSG1SMXc/view?usp=sharing
If you already are on B111 the way back may lead you in disability to charge the battery. So most people here will say NO. That was also my experience. But you can try that and report, if you see the light and lightning icon for charging. This would be interesting.

i will tray but if it cant charging can i return it ???
and which room hasn't Chinese language

Do a Backup in TWRP before you start the dload from the GUI.
If you have flashed the universalt cust you will see that the Andriod verson and storage Info will be correct.
But if did not go thru B106,B109,B111stock you will not have a full working Android 5.1.1. If this would be possible Huawiei would offer the dload for B111 if you are ond B106. No they don't. They inform you to upgrade to 109 via OTA or dload. When on B109 you will get the message tha there is a update for B111. So I guess we have to go that way, even if it seems that you have installed a B111. You have the wrong infos in the "about phone" and the universal cust is inside the B111KangVip.zip file. So this is curious. Start with flashing universal Cust, then flash 4 images for B106 and then go all steps via dload.

flashed the universalt cust and information still error

Do a Backup within TWRP (NANDROD) . Then do the dload after you have started the rom.
All ROMs for the 703 start in chinese, but you will be able to set the language. B111KANGVip has removed the most chinese.
---------- Post added at 10:45 PM ---------- Previous post was at 10:36 PM ----------
Ok if you still have the information error this is an indeed, that you must do all steps going thru all the fw versions.
Do that NANDROID of incomplete B111. If you have the "not charging problem" turn the device complete off to charge for a while. If it does not charge do a recover of the B111 to charge, then continue.
Start to install B106 and follow my instruction list http://forum.xda-developers.com/showpost.php?p=64623653&postcount=378

4. b This flashes GEM-703L official stock ROM b106 via dload folder. [This flash maybe abort on about (90-95%), but this does not effect the next steps] Wait to press ok until you have exchanged the dload folder for the next steps.
i wont do that setup restart and do nothing

Do you have your original cust folder or your original rom? You may have a different cust folder based on your region and I can add your cust folder to the cust mod so when you flash it your information will be correct.

i reinstall all and still stuck in fouls information

Problem of switching back to Gem-702l android6.0

Hi,
I really need some help. My phone is gem-702l model, on B112 stock rom of 703l.
Now that Huawei has released a stock Android 6.0 (B201) for gem-702l, I am thinking about switching back.
Here are the thing I did and problem that stopped me.
1. I updated to B209 following the instruction in XDA without any problem.
2. When successfully on B209, I downloaded my stock B201 rom in Huawei website and extracted the 5 required img files: recovery, system, boot, cust, userdata
3. I fastboot flash the 5 img files and reboot. So far so good. The About Pone is correct except internal storage volume.
4. I factory reset and format the internal SD. Now everything in About Phone is correct.
5, I put the dload of b201 in my MicroSD. Strangely there's no "update from SD Card" option, So I use the three key(power, vol+/-)to hard flash the whole dload directory. It failed.
THe problem is : it seems that I can only fastboot flash 5 img files of 702l, there's no way of doing the whole dload update.
Now my phone is not fully converted to Gem-702l. it's kind of half 703l and half 702l in android 6.0.
Is there anything I missed or anything I can do to make it fully converted to 702l?
Please help! thank you so much.

Now my phone is not fully converted to Gem-702l. it's kind of half 703l and half 702l in android 6.0.
Is there anything I missed or anything I can do to make it fully converted to 702l?
Please help! thank you so much.

First you need to go back to the last 703L 5.1 system (B112) then flash the universal cust mod, then try the dload to B201. You also may have to go back to the last 702L 5.0 rom before you try to update to B201 but i'm not totally sure.

thanks.
I downgraded to B112 successfully and then tried the dload update. It didn't even go through the first 5 seconds and failed. I guess it's because my phone's on 703L cust so the 702l stock rom didn't apply to it.
As for downgrading to 5.0, there's still no way of doing that for 702l, so I am still stuck here.
******edited***
I just "fake flashed" back to5.0, which means fastboot flash the required img files, and tried to dload update to B201 of 702l.
It's still not working. Now I am at my wit's end.

Flash the B112 universal cust in TWRP then fastboot flash back the stock recovery, then try the dload again. If that doesn't work, flash twrp, then the cust mod, then the stock recovery then so a factory reset from settings. If the reset completes successfully then flash twrp again then the cust mod then stock recovery then try the dload method again.

That's exactly what I did. The dload just wouldn't go beyond 5 seconds.
The problem, I think, is that the universal cust marked the phone as 703l(that's the point of universal cust), but the stock rom B201 is for 702l. Therefore, the first 5 seconds of dloading when it verified the model, the stock rom and the model just didn't match. So the dload failed.
There's no flashable cust for 702l to make the phone match the requirement of stock B201 rom. I think this might be where the problem is.

The cust mod includes the cust from the 701L and 702L as well so it should work as long as you go back to B112. What is the reason you want to go back to the 702L firmware?

There are certain functions that only exist in my region, such as the nationwide SMS warning regarding natural disasters. It's a system that being developing in my country. All phone brands will integrate the thing in their roms and push out for OTA. I would like to be on the receiving end. Also, If I need to RMA my phone someday, it will be nice to be able to switch back to stock rom for warranty.
I thought it was easier to switch between models when they were both on the same version of Android. I was wrong.

Hello,
Where can I find the Android 6.0 (B201) for gem-702l ?
Thanks

Here. But it's for Taiwan gem-702l and it's still a test version, I am not sure if it's applied to other region.
I'll advise you to wait a bit longer for the official version to be out.

Ok, thanks for the input!

How to FULLY convert back to gem-702L.

Updated Nov. 23, 2016:
For 701l users, if you need to downgrade, check out dimitarnc's post of how a 701L downgrading to B005 here
http://forum.xda-developers.com/showpost.php?p=69747367&postcount=6
===========
Gem 702L user's downgrade guide:
For people who want to convert their devices back to 702L and downgrade, there's a way. After Huawei Taiwan releases a downgrade pack, it's actually easy.
Result:
Battery charging is normal.
Debugging mode can be turned on.
Basically everything just working!
You have a functioning stock gem-702L.
Cautions:
1, My device was purchased in Taiwan. All files I used in this process are for TW gem-702l. Please download all the necessary files in TW version, just in case.
2, I am not a dev. I have no ability to help you if you brick your device. You need to consider this before you decide to go ahead.
Alright, here we go.
Preparations:
1. Download 702L downgrade pack (it's only 2 kb): http://download-c.huawei.com/download/downloadCenter?downloadId=81363&version=323452&siteCode=tw
2. Download 702L TW B005 stock firmware(1.25gb): http://download-c.huawei.com/download/downloadCenter?downloadId=59524&version=193667&siteCode=tw
3. Download 702L TW B005 flashable cust zip (Thank ajsmsg78 for making it a while back):https://dl.dropboxusercontent.com/u/19718077/CUST-GEM-702L-D001.zip
4. Download TWRP-ENG-5.0.img (please find it somewhere in the forum).
Process:
1. My device was on 703L Android 5.1.1. I am not sure if you can do it directly from android 6.0, feel free to try or downgrade to B112 stock first.
2. extract boot.img, cust.img, system.img, userdata.img, recovery.img from gem-702l B005 stock rom, and fastboot flash all of them.
Boot up your phone, do minimal setup. Now everything in "About phone" is correct except the internal storage volume.
Do a factory reset and format internal storage. Now everything in "About phone" is correct.
3, optional:
if your "About phone" is all messed up, you need to do this. Otherwise, not necessary for legit 702L devices.
Flash twrp 5.0, then flash gem-702l b005 cust zip. Then flash stock recovery to format your internal storage.
4. Extract files from the downgrade pack. Put the dload directory in your SDcard. Manual update it. It should go through 100%.
(If it fails, that means your system's still on Android 5.1.1, and this method doesn't apply to your device. No need to go any further, just flash back to gem-703L ROMs and stay there.)
6, After the phone boot up, copy the full gem-702l B005 stock firmware to your SDcard, manual update it. It should go through 100%.
Voila! You are back.
Now you are on gem-702L TW B005, You can upgrade to B201 if you want, or flash back to your regional stock rom.
Here's my phone back to gem-702L and upgrade to B201.

What if I am on Kangvip B211?
Do i have to go back the whole way or can I just put the Rom and the Cust from 702L on my converted 702?
Thx, Ray

I'll say it's safer to get back to stock B112 (Android 5.1.1).
you need to do a fastboot flash of B005(android 5.0) imgs during the process. I am not sure if you flash an android 5.0 img in Android 6.0, it won't go into bootloop or something.
It takes certain procedure even for a 703L to go back from 6.0 to 5.1.1, so I wouldn't recommend you to do the fastboot flash directly in Android 6.0.

This is a big effort and i d'ont know, if this fits for the Rom..........
I think i ll stay at Kangvip.
Thy for ur reply.

No problem. This is a backup plan.
Now that there is a safe way to get back, we can switch between 702l and 703l roms anyway we like it.

You must extract boot.img, cust.img, system.img, userdata.img, recovery.img from gem-702l B112 stock rom, and fastboot flash all of them First.

Great guide. I can see this being useful for anyone wanting to sell their phone and bring it back to stock after they already converted. I'll probably keep mine converted as the same thing with updates will probably happen in the future.

Install TWRP and try wiping system first.

What about the 701?
Would it be converted to 702 that way?
Could we change it to 701 after running downgrade script via fastboot flash b003 files from 701 and dload B003?

I think the trick is how to cheat the System that your device is in certain region for local firmware dload to work.
And that is where editing oeminfo sets in.
For 701L, since there's only downgrade pack for 702L or 703L, you need to downgrade as a 702L or 703L.(I recommand 702L because it's easier)
Now when your are on 702L B005, next step is to edit oeminfo to switch back to 701L.
You need to edit your oeminfo to eu. Then you can flash any Eu firmware, in this case, B003 701L. Then you are back to 701L.
I don't have a 701L so I can't try. but here's an instruction for Huawei devices to switching regions.. You edit your oeminfo to hw/eu(europe), then you can cheat the system that you are now an Europe device. It will let you go through the dloading of B003 for 701L.
Maybe someone wants to give it a try.
If it works, we might not even need that much work to switch between 703L and 702L/701L, we can simply edit our oeminfo and Voila!

Thanks for outlining the steps - I managed to bring my 702L on 703L-B109 ROM downgrade back to 702L-Taiwan-B005 and then upgrade to 702L-Taiwan-B201 Android 6.0 !!

Guyzz. For those who upgraded their phones to B201 .. do you have any bugs ?
I installed the rooted version on my 701L and it works fine but i have some issues with some web apps .. and i have strange error in the system log ..
Am not sure if that bug exits becuase it's a beta build or just because i converted my phone ..
Does anyone know what's happening

Sorry I've been playing around different roms so I just switched to 703L B111 near stock. I am not currently on 702L.
But when I was on it, there was one thing. One of my game apps counldn't connect to my Facebook account due to some "Hash key invalid" in B005 firmware, But the problem was solved when I upgraded to B201. Other than that, everything worked fine.

If you want to switch back to stock 702L from 703L roms, you need to do the full downgrade and conversion.

HI all,
i'm stuck at trying to dload the downgrade package. Somehow dload method doesn't startup, no matter which way i try: Updater=> Local Update or Vol Up+Down+Power.
Local updates does nothing and ends up normal boot up after another restart.
Vol up down pwr goes to TRWP.
Any help is appreciated.
Thanks and Regards,
Kevin Chan

I had similar situation and could solve it. I can not exactly remember, but it depends also on which version you were before.
In TWRP do factory reset.
In bootloader mode flash recovery boot and system.img from b112.
After system start do factory reset on EMUI. If system does not start try same with b106 files.
If you are on B112, dload update.app for B211 and then dload update.zip to B211.
In this state the downgrade script may run.
To continue normal install KangVIP or b203 international.
My device: 701->703 B211 xposed 86
