Root Stuck with Download Mode and Stock Recovery, in a Bootloop. **Making the most of Download Mode**

[HasH_BrowN]

So I got stuck with download mode when flashing ZV6 update without TWRP.
http://androidforums.com/threads/zv6-ota-released.943636/

I flashed the update on my wifes "Data Done Right", lost root, got root, and now working okay. Tried using Xposed and a number of modules (the same ones I use on my VM Tribute) and caused a bootloop. I couldn't use the Xposed disabler, for some reason stock recovery replaced TWRP, so I factory reset (still had root). Reflashed recovery through Flashify.

I did use factory reset in stock recovery to boot back up.

My question is this:

How do I flash/install a recovery.img in download mode? Can ADB be used somehow (probably not)?

I tried everything I could do before the factory reset. PIA!! I've gotten stuck like this with my Nexus 7, but there is that nifty "WugFresh NRT" to fix things.

Any help/insight would be appreciated.

so after trying to find the orinal way to install fastboot i refound this thread

http://forum.xda-developers.com/android/development/guide-root-method-lg-devices-t3049772

which allows a serial connection thru download mode. not sure if use full

also post on the end of this thread

http://forum.xda-developers.com/android/help/lg-tribute-development-t2953342/page1

and ask undev "Unjustified Dev" what the original way was to install fastboot because he deleted the guide.

 

[HasH_BrowN]

Excellent.
That would explain why I couldn't find it.
Thanks for finding the links. I got so sidetracked, it wasnt even funny.

ive been there man i was one of the first people to brick my tribute with an ota.
and when i did it their was no fix. so i had to ask on the xda from but no one had anyway to fix it.
so after 3 days trying to fix it on my own i finally re flashed the stock boot loader.
the point is those 3 days sucked.

also on xda you did not tell them that you dont have access to android or twrp.

When I posted I did have access. I mess things up all the time, on purpose. I factory reset (ultimate goal of avoiding), then reflashed recovery. Everything works fine, I just couldn't find how to get into fastboot. I did do it on mine back around April and of course didn't copy it anywhere, but needed it when my wife got hers. It just irked me that I forgot it and got stuck with only download mode to work with.
There is always more than one way to crack an egg, skin a cat, (or pick your own euphemism).

Put the recovery image in the root of an SD card. I'll call it recovery.img.
Do steps 1, 3, 6, 7, 8, 9 in the rooting guide:
http://forum.xda-developers.com/android/development/guide-root-method-lg-devices-t3049772

Then at the "#" prompt, enter commands:

sh
dd if=/storage/external_SD/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery

Use the correct recovery image name if yours is not recovery.img.

You should be back at the "#" prompt if nothing goes wrong. At this point, the recovery is installed. Either type "LEAVE" to reboot, or unplug USB and pull battery.

Note: For anyone still with stock recovery, I'd recommend backing up the stock recovery in case you need to restore it to take an OTA update. To back up, after the "sh" command but before the "dd" command above, use command:

dd if=/dev/block/platform/msm_sdcc.1/by-name/recovery of=/storage/external_SD/recovery-stock.img

The stock recovery is saved as recovery-stock.img (or whatever name you use) on your SD card.

Excellent advice.
I forgot about the command for replacing LAF, but this really helpful.
When my wifes phone received the update it replaced TWRP with stock recovery. Then locked out the use of stock recovery. Plus it bounced root. But everything's fixed.

Get the drivers and root downloads on that link, then since you have download mode start with step 6. Then post back here.

 

[Arlyn_1994]

I am on stock rom without root without custom reocvery. I am stuck at lg logo. but still able to boot into stock recovery. Since I am not able to boot to android system, then I am not able to root it and install custom recovery.

However I am in download mode and able to use fastboot devices to see my device. any suggestion I can do with the fastboot inorder to recovery my phone?

The steps I described in #8 use shell access provided by download/laf mode, but I think the shell program itself is invoked from the system partition. In other words, if the system partition (/system) has become inaccessible, it's likely the shell would not work.

What can we do if the shell doesn't work? I don't know yet. I believe if "laf" (triggered by vol-up and usb, with a screen saying "Firmware Update" and "Do not unplug the USB connection until the process is complete.") fails, we'd get fastboot. So does "laf" mode work? Does the phone enter "fastboot" mode?

I have not personally used fastboot, but the steps to flash a partition can easily be found with Google (fastboot flash recovery recovery.img). Normal unbricking procedure with many LG devices requires a .KDZ or .TOT firmware file. Someone has mentioned that a .TOT file for Tribute can be purchased. Recently, .KDZ files for Tribute's sister devices (Transpyre and F60) have appeared. Even if LG doesn't release one for Tribute, it might be possible to construct a .KDZ file ourselves. Don't quote me on this though. I'm still learning as I go.

Transpyre and f60 custom roms are compatibility?
Sorry for my english!

Not quite, but as far as I know, they are all built on the same platform (I think their cases are compatible) and they are more similar than they are different. Developers have been able to use bits and pieces for one device on the others.

ok more than anything there CM12 wonder to this mobile does not work the camera and not talked about every 5 seconds vibrating like crazy thanks for the quick response brother!
