I would Not recomnend that. This way will erase the fitting cust on 701 models. I don't think the cust it's a nice goiter which we can replaced by a randomly selected one. Why do you think the device runs in bootloop on this guide?
This is more complicated than the way AJ figured out.
The 'universal cust 112' is the key.
I did it on 3 devices now with 100% success in dload and no bootloops.
2 factory resets and 3 dloads (106 112 and 209) are necessary.
Then install 202 or 211 KangVIP from AJ to have a full functional rooted ROM with your origin cust you came from.

Perhaps indeed it replaces information of 701, I am not a specialist.
The bootloop when its causes are on both models 701 & 702.
Despite this my tutorial that my 701 & 702 work perfectly with the wifi and bluetooth.
I do not question the quality nor the audioralf skills,
I just shared my tutorial after many trials of other tutorials that never It Works for me.

Well you link files you don't write where you got them from and don't write for wich model they are made for and what are requirements they based on.
Maybe it works, but it's a risk to continue on a bootloop with further installations.
The regular way works without errors.

If someone is looking for another dirty short way :

Simply run the official downgrade script from 6.0 to 5.0. for 702.

It even runs on a 5.0 701 model.
After this it behaves like a 702.

Then you can dload the regular update to 6.0 for 702 models.

After this flash TWRP 6.0 and install AJ b211

This method is also dirty because you loose the 701 cust for your region and hardware
This may be have consequences we don't know.

So better go the regular way AJ had figured out and ask in forum if you habe problems.

B111 SimpyGoogle => KANGVIP B211 link?
Hi Audioralf,

thanks for pointing this out. I followed your great guide and got to SimplyGoogle B111 on a GEM-701L. (You updated it with a shortcut to B111, which worked just fine. Some lines in the guide are a bit misleading due to the newer shortcut but all is great).

Now I'd love to get to KANGVIP B211 on Android 6. But how do I get there from B111? I can't find AJs guide you pointed out in your comment. Could be please post a link? (I have searched but without success).

I did succeeded with a mixture of both methods.

I started off following the "original version" of AJ and when I never got into upgrading into 6 I decided to stay at Near...B111.

When I saw Oblemay's tuto I decided to try it. Funny enough, coming from B111 I (701l > 703l) I never got the boot loop!
Also, since I was not able to unpack the rar file from step 6.2 I simply ignored this one and continued with 6.3.
Guess what it worked perfectly. Only issue was unstable wifi until I did a factory reset from within 211 (not TWRP)!

I am very happy with my former 701l now on Marshmallow. Thanks to AJ and Oblemay - Maybe it worked for me with Oblemay's (reduced) version as I also live in France .... Do you also have problems with the mail app in 211?

It could be really good to have some clear way... Actually I was asked about such process by one of russian friends who own GEM701 and do not uderstand nothing, specially using Google translator . As I am owner of GEM703L I am not familiar with 701 ways... But I want to help my companion...
