[LG V30 Questions & Answers] ChazzMatt:
Japanese "V35" is really V30+

Keep reading, I'm taking care of the boring stuff first. ;)

1) I'm answering your question here in the Q&A section. Please do not ask general questions about a phone in custom ROM thread. Your question has nothing to do with that ROM, where you posted your question.

2) This is the V30 forum, not the V35 forum -- but your phone may be an exception. I'll explain in a second.

3) Kingo root app? Please. Nothing like that is going to bootloader unlock and root a V30 or V35. It's only going to try to infest your phone with malware and send your IMEI back to China. There's no such thing as 1-click roots for V30, V35, G7.

4) If you were interested in rooting your phone you would have researched here on XDA first before buying the phone. There are many phones which do not have root and will never have root (2015 Kinzie Verizon Droid Turbo 2, for instance.) Even when seemingly guaranteed root, like with LG's "open market" US998 V30/V30+, LG broke it's implied promises. Only thanks to their wonderful Oreo bootloader unlock exploit which [MENTION=6158380]TxanMoe[/MENTION] found does every V30/V30+/V30S -- except T-mobile H932 -- have bootloader unlock and root. Point is, don't buy a phone without researching first. Don't buy a phone, then come to XDA to find out whether it can or can't be rooted.

5) Now the good stuff. Japan LG phones are DIFFERENT. They demand different model numbers, sometimes different specs. Japan also still uses the 4G WiMax protocol, besides using the 4G LTE protocol. (Google if you don't know what WiMax is.) The Japan LG V20 was called the LG "V34", and had different (smaller) dimensions from the LG V20. Internally it was an LG V20, but for the Japanese market it was V34 (isai Beat).

Japan-exclusive LG V34 is a 5.2" waterproof version of the V20

It was ONLY released in Japan.

What does that have to do with YOUR 2017 "V35" phone? The Japanese V20 was called the V34. The 2017 Japanese V30+ is called the "V35". It is completely different from the 2018 LG V35 released here in the U.S. and to AT&T, B&H Photo, and Google Fi. The Japanese "V35" was released last November 2017 to Japan with Oreo already installed, and is exclusive to Japan. It's a V30+ for Japan market called "V35", as the successor to the V34.

If you go here, to LG.com website for Japan (note this is OFFICIAL LG website!), and use Google translate....

https://www.lg.com/jp/mobile-phone/lg-LGV35

You will see it's a 128GB V30+ with 4GB RAM and Snapdragon 835.

Towards the bottom they even mention the free VR goggles promotion for the V30+:

So, your phone is really a V30+, it really is JOAN (not the JUDYP of the other 2028 V35). It possibly can be bootloader unlocked and rooted, and use [MENTION=3475147]SGCMarkus[/MENTION] JOAN TWRP for V30.

And yes, this is totally confusing for all the other 2018 V35 owners who have been correctly told their phone is NOT a V30 and is totally different. But using one of the CPU type apps on Google Play, you can easily see the difference is YOUR phone has Snapdragon 835 and the other 2018V35 (AT&T, Google Fi) have Snapdragon 845.

6) I had researched a little about the Japanese 2017 V35 before and thought the Japanese press was mistaken in calling it a V30+ when it was released. I thought it was just the first of the V35 which were then released here in the U.S. a few months later. No, from the LG.com website the the Japanese "V35" is indeed a V30+.

How do you bootloader unlock and root it? How do you carrier unlock it? You would have revert back KDZ with pre-July 2018 security patch for

bootloader unlock and root, IF your phone has fastboot flash commands

. If it doesn't then you would have to

Frankenstein

(convert) your V30+ to a

carrier unlocked H930DS

, which does has fastboot flash commands. That would also carrier unlock it, if it doesn't totally brick it. I assume you don't need the WiMax 4G stuff? Only LTE? Being "exclusive" Japanese, it might have some of the complications the Korean V30/V30+ variants have. They have to flash to H930, bootloader unlock and root, then flash to US998 to get modem back working.

Good luck!

7) You have an interesting phone -- but if it's carrier locked to a Japanese network you don't use, then it's not much use to you. Theoretically, you can bootloader unlock it, and possibly carrier unlock it. But it's going to be a lot of work and there's probability you will brick your phone. I really don't know about the Japanese V30+ variants... Whereas, you can buy "mint" LS998 V30+ on eBay for a little over US$300 and easily Frankenstein them to carrier unlocked US998 V30+, bootloader unlock and root them. See point #4. Research FIRST before buying a phone.
