Currently I have Gem 702L B003, with no chinese apps and do have google. If I go and install Gem 703LB106, will that install the chinese apps and I lose playstore?
Hi - I've also got a 702L & would like the updates of the 703L - can I flash my ROM with 703L & then start updating ??
Many thanks
Paul
Still searching on this, dont think there are many using 702L on xda!
I have the same problem... have 702l and want flash 703l...
Try flashing it and report back. You can flash it through fastboot after unlocking your bootloader.
Still waiting to unlock the bootloader - at least another week to wait, maybe 10 days...

Must I go back to Stock recovery TWRP to update by this method or it does not matter ?
If I must come back to Stock recovery , How Do I get it ?
You can use the Huawei update extractor, extract the RECOVERY.IMG and flash it via fastboot.

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.

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.

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.

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.

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 ?

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!
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.

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.

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!

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. Therefor, all files I used in this process are for TW gem-702l. Please download all the necessary files in TW version, just in case.
I think it works on all 702l devices of other regions (I can't see why not).
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 TW 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 B112 stock. 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.
Let the phone boot into system, do minimal setup. Now everything in "About phone" is correct except the internal storage volume.
3. (I am not sure if this step is necessary but I did it anyway) Flash twrp 5.0, then flash gem-702l b005 cust zip.
4. Flash stock recovery, then do a factory reset and format internal storage. Now everything in "About phone" is correct.
5. Extract dload from the downgrade pack. Put the it in your sdcard. Dload 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 B112 and stay there.)
6, Aftet the phone boot up, copy the full gem-702l B005 stock firmware to your sdcard, then update it by dloading. 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.

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.

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.

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.)

Hi - I need this stock ROM and can't find a download link anywhere. can you drop it to me? GEM-702L / V100R001C209B005CUS
Hi. After start android nearstock rom. I hear some noise from speaker and then restart. Again and again . I come from gem-701L b003 to gem-703L b111. Then b211 Kangvip slim. But WiFi and Bluetooth not working. Then I try reinstall nearstock.
(make backup before that)
flash boot system and recovery from B106 in bootloader mode
Then start B106 and do factory reset from EMUI menu including format internal SD
Then restart and connect WIFI. You will get OTA to B112
put the file update.zip (from B211) in dload folder (not unzip it)
Then run from GUI local "partial update" for the update to 6.0
Then flash the TWRP for 6.0 and install AJs B211 KANGVIP version
Then restore your data.
Thanks.yesterday managed to reinstall kangvip slim B211 . So now I have to extract system and recovery of B106?
When I flash files from B106 will then brick from my phone ?
