Um... What? I made the zip to upload a backup of my tablet without anything personal. I backed up everything I could via twrp. Unzip the file. Place on SD card. Restore in twrp. It worked for me but then again its my tablet. Hope it helps someone who "bricked" their at&t v410

Soooo...I see on lge.com that there are 2 separate files labeled android and one labeled kernel. Could it be that they put up Rom source?

Nah, those are the proprietary libs, binaries and apps that LG packages into their firmware. That kernel source will come in handy though :)

Not sure if anyone noticed but I posted the Stock ROM over in the Android Development section.

Also I'm working on a stock based ROM that is de-bloated, deodexed , zip aligned, rooted, etc.
Any chance that you're experienced enough to create a stock Lollipop ROM once you're finished creating the one you're currently working on? Or would that be impossible without LG releasing Lollipop kernel source for our 410?

By stock I'm assuming that you mean an LG Lollipop ROM which would be impossible becuase they haven't released Lollipop for the tablet yet. I am however going to be working on AOSP Lollipop ROMs, i.e. Cyanogenmod 12, etc.

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

.

Thanks Tim!

** [ BEGIN EDITED SECTION ] **

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://forum.xda-developers.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.

Thanks Tim!

When the time comes, will we flash a Glad 7" model v410 LTE (AT&T 4g) via TWRP or CWM or DD or via Nandroid Script (with or without Apk front-end)?

I think some lying bullshisters (or morons who cannot id their own model) said they were using official TWRP/CWM "without any prob" on a v410 -- a few months back, but it's been a while.

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 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.

I could have missed it of course, if a post was randomly made to one of the 4 diff places gad 7 users have been, since the generous mods have COMPLETELY IGNORED CLOSE the MANY MANY official, polite, requests for a gpad 7" forum. I tire sometimes of the endless searches of unorganized irrelevant search results via poorly designed navigation and search tools.

can you please give me a link to the recovery you flashed? Or to the post/thread for it? (Just to confirm, you have/are flashing images using a recovery on a v410 (not a v400) CORRECT?

Not so sure what you're asking for but if you go back in this thread to page 32 and comment number 316 you'll find the working bumped TWRP for the v410..

That's what I'm using. I'm not stupid. I guess I should make a signature stating all my devices I own/owned and what I've done with them for his viewing pleasure.... ;)

Actually, I shouldn't have said stock Lollipop...I meant vanilla Lollipop, no pun intended, haha. So glad that there will be some ASAP Lollipop ROMs in the works for our 410!

I'm hoping that ART will make this device much more capable when it comes to multitasking. Currently, it's pointless for me to use the built-in split-screen capability, as most apps close, leaving only the other on-screen. A friend of mine who is usually more tech-savvy than myself told me that because I rooted the device, it's causing the multitasking issues, because LG devices always have issues when rooted for some reason. That doesn't make sense to me though...does it to you?

I gotcha. Yes I am working on getting us to a place where we can have some AOSP ROMs. You will notice a night and day difference with those ROMs over LGs stock firmware.

The multitasking issues are typically slow and laggy across most device when stock. I would say that LG is especially bad though.

As for ART, you can use that now on KitKat. It's in Developer Options. It does make a difference in performance

After root, do I have to unlock the bootloader first to install custom recovery?
If not, do I have to unlock bootloader after installing custom recovery?
Do we ever need to unlock bootloader?
