COMPATIBILITY of TWRP and Roms for v410 and v400 and between WIFI only vs. WIFI+LTE.

HOW TO FLASH ROMS & RECOVERIES:

AFAIK, it is possible to flash most androids (including the LG G-Pad 7" model v410 LTE, AT&T 4g) via TWRP, CWM, DD or Nandroid Scripts (with or without Apk front-end). Apparently, it can also be done in Fastboot.

CAVEAT:

I've heard its a bad idea to try v400 CWM/TWRP on v410 (I'm not sure if anyone has reported def. success with that), and THE ONE AND only person (hcgonzalezpr) who I recall promising a recovery compiled for v410 specifically said they had some limited success with CWM on a v410 but did not release or publish a link to any binary, instead saying they had decided to go with TWRP instead and promised to share it ASAP. Here is the link to their TWRP Build: http://xdaforums.com/showpost.php?p=57842616&postcount=316

COMPATIBILITY OF RECOVERIES (between v410 WIFI and v410 LTE):

Other than diff.'s in the actual manufacturers model (which might affect hardware and drivers, etc.) I can't imagine HOW it would make any diff whether one's gpad is with or without cellular, when choosing/compiling a basic, no frills recovery, at least, for the basic functions most recoveries include.

NOTE: I missed it (of course), when the post of TWRP (via link above) was made to this thread, because it is only one of the 4 diff places I've found that GPad 7 users have been posting; because the mods have not created a forum for us (despite numerous official requests for a new forum for us). It is also a bit tiring sometimes to wade through endless searches of unorganized irrelevant search results via poorly designed navigation and search tools.

HELPFUL CLARIFICATIONS: what is true of ROMS & Radios is NOT (in the vast majority of cases) true of the 2 most popular recoveries (TWRP & CWM), when it comes to flashability (compatibility for flashing) between the cellular+Wifi vs. the Wifi-ONLY variants of the SAME model tablet.

** [ END (mostly) OF EDITED SECTIONS ] **

Note that gpad and g3 are NOT models in the sense I am speaking of. Those are marketing words. Actual (more specific) model names such as v410 and v400 identify tablets each with yet further sub-model variants (and likewise, the D850 is a model of the g3 phone). Sometimes with a single model of phone (e.g., the XYZ-900) the sub variants will be incompatible (or barely/crippled compatible) with each other's ROMs, for example, due to radio packet characteristics other than cellular frequency, between China/Asia and US/Canada and EU.

So ROM's (the main Operating System that you normally use after bootup) are probably compatibly between all v410 WIFI tabs, but NOT between the v410 wifi and the v410 Lte. Likewise, neither TWRP or CWM are compatible between the v410 and the v400, HOWEVER, the TWRP and CWM recoveries should both be inter-flashable, between all versions of the v410 that we know of in these forums (thus far), whether wifi only or LTE. Note that everywhere on XDA when someone writes 'flashable', they mean that it is desirable. Sometimes (rarely) a flashable binary (compiled software) won't flash till the second time around, so double check its hash (PLEASE, ALWAYS publish hash values for any file you share). Likewise, sometimes a flash might complete for a bad or incorrect/undesirable file.
