init.gammaw.class_core.sh (you could have mentioned its name :p ) Yeah these shells are from the ramdisk in boot, recovery and laf partitions, and have always displayed in my file managers (since root). Dynamic memory management, I believe, is different from dm (device mapping ) verity that is referred to in the article that I posted. But these shells may do play a part in the show. I'm not a coder, but I can glean some rudimentary information from some of these. And it especially helps when they are well commented. ?

Edit:

And looking at the comments, I think I see what you mean.

Edit: Maybe can modify kernel to disable dm verity, so as to allow modifications. Complete source may, or may not contain bootloader. We'll see. Downloading now (although my 32bit machine won't compile it).

Edit 2:

All that source is the kernel and proprietaries (vendor, external, etc.). But may gain some insight before download of full kitkat source. We'll see.

Download Mode Access

Toxinburn,

I have been going through this thread and found this particular hack very interesting but I could not do myself. I was able to root the phone using Towel Root. Once I had root, I sent the following commands through adb:

1) "ls -l /dev/block/platform/msm_sdcc./by-name" to show all of the partitions on device

2) "dd if=/dev/block/mmcblk0p15 of=/dev/block/mmcblk0p17" to write laf partition over recovery

3) "reboot recovery" but at this point the phone becomes stuck at LG Logo

Can you please tell me what I'm doing wrong. I'm thinking once we have download mode can attempt to flash over device with LG L90 firmware.

Thanks!
[Android Q&A, Help & Troubleshooting] toxinburn:
If i wanted to write the laf over recovery i would do....

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

That makes a backup of the recovery

dd if=/dev/block/platform/msm_sdcc.1/by-name/laf of=/sdcard/laf.img

Makes backup of laf recovery

dd if=/sdcard/laf.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery

That will push the laf over recovery

I have tmobile l90 d415 i can provide any parts you need also what from l90 are you thinking of using?

I was able to boot into download mode! Thanks for the help. I see some USB ports load while in download mode but I don't have a tool that can connect to phone right now for flashing. It would be ideal to have fastboot instead to be able to flash modified boot or recovery image.

Brick?

I have also managed to brick my LGL34C. Due to my own stupidity of course (trying to swap the sd cards), the phone just sits at the lg logo and of course the bootloader is super locked down on this model. It appears it can be connected via adb but adb says device unauthorized. Is there any way around this? Any ideas would be appreciated

Don't understand how that could brick the phone. Unmount sdcard before removing? Need to start a thread: "All ways to brick LG L34C".

Found some good information on a dated thread for boot sequence/ choices:

http://xdaforums.com/showthread.php?t=1856327

Pay special attention to qfuses, voting. This is for different processor, but should be similar. According to this, rpm is primary bootloader. So I don't know how aboot fits into the sequence (appsbl?). Haven't read the whole thread yet. There are also similar (newer) threads.
[Android Q&A, Help & Troubleshooting] nakperry:
Radio Shack has the LG-VS415PP for $40. Verizon has the phone locked in the setup screen. I had to setup an account in order to get passed the screen

As for as I see the bootloader is locked and there is no recovery option in the fastboot mode.

is this phone related with L34C? how to get to where showing in the photo?

this looks promising for me because i believe if my L34C can get factory reset, it probable will be live again!
[Android Q&A, Help & Troubleshooting] nakperry:
Yes, this is Verizon's version of the L34C . To get to the menu, volume down and power . It will be promising if someone can modify the menu to allow a fastboot option.
[Android Q&A, Help & Troubleshooting] everseen:
unfortunately L34C does not boot into menu for Vol down and power :(

tried every combination before like vol down + power, up + power, up + down + power, down + home + power, etc. none makes difference other than normal boot.
[Android Q&A, Help & Troubleshooting] nakperry:
The only option that works for the LG34C is Safe Mode by holding the power and volume down and then release power and keep holding volume down.

I assume you read previous posts and tried jumping the battery terminals to discharge any memory settings and I would hold down the power button with battery out and no power cable, too. That worked for me when my phone was stuck in a loop.
[Android Q&A, Help & Troubleshooting] everseen:
Thanks for help on this. Still didn't succeed. hope my post does not divert the thread.

Tried LG mobile System Tool for safe mode. it recognized my phone AS L34CV10, then I started upgrade recovery, but always got error saying like "connection problem, disconnect phone pull out battery then try again".

also tried quite a few times for safe mode by down + power without success. have questions:

1. is power held when battery back after 5 seconds holding? I managed to hold power all the way from start until battery back and start buzz.

2. is phone screen still black when release the power? it seems LG logo appear at the end of buzz.

3. when safe mode appear? before LG logo or after LG logo or after blue track phone screen.
[Android Q&A, Help & Troubleshooting] nakperry:
Just release the power button once you are sure the phone is on, don’t worry about timing it you have plenty of time, I was able to boot into safe mode by pressing volume down at the end of the LG screen cycle, too. The safe mode will come up after the blue track phone screen.

I assume you are not able to access through the adb command prompt and you are stuck at the unauthorized device prompt. Maybe just keep entering adb shell and see if there is a system quirk and it allows you access.
[Android Q&A, Help & Troubleshooting] nakperry:
I was playing around the LGL34C hidden menus and I see the Battery option, the Charging Bypass Boot is grayed out, if this option is enabled the battery charging screen would disappear and the phone will boot once connected to power, would this help in creating a fastboot mode?

I tried changing the com.lge.hiddenmenu_preferences.xml settings from 1 to 0 , but once I reboot it reverts back.

Any insight into enabling these options would be appreciate.

Commands:

adb shell

su

cd data/data

am start com.lge.hiddenmenu/com.lge.hiddenmenu.settings.Settings
[Android Q&A, Help & Troubleshooting] everseen:
my L34C always stuck at blue tracfone screen when boot, maybe that's why it can't get into safe mode. adb devices shows empty, although my computer shows 3 hardwares found when connect phone to pc:

USB Composite Device Ready to use

LGE AndroidNet USB Modem Ready to use

LGE AndroidNet USB Serial Port (COM19) Ready to use

it seems a dead end for me.

btw, here is how i bricked my phone:

i did a factory reset, then booted into system, LG setup wizard kicked in, I was bored then managed to get into application settings from accessible button in wizard, then disabled wizard, reboot...

L34C service manual

Well, I was looking for the service manual for the L34C (not the regular User Manual, but the detailed one with schematics, etc.), and it does seem to be available from a rather nefarious spot. In fact, they supposedly have a firmware, too, but these items are being sold, and are not freely available. That said, the 1000 credits they ask for the manual is apparently only $20 so maybe it is worth it? I tried to supply a link, but I can't because I'm a newbie. So instead, if you are interested in seeing this, do a Google search for "LG L40(L34/L34C) TOT/KDZ/DLL Download", and pick the "forum-93-1" link (should be top of search).

[Android Q&A, Help & Troubleshooting] ibub:
No luck. QFPROM has already been written to, and as far as I know, irreversible. So no access to fastboot or recovery by key combination. No way to bypass verity checks, so no custom recovery. [emoji20]

Thanks, and I'll post the link for you:

:)

This is for Motorola, and is only slightly dated (one year). But Qualcomm in both. After reading this (and understanding a little) it seems that I might have conflicting information. This basically says that a qfuse must be blown (written to ), in order to unlock bootloader. But the Qualcomm tech release from the thread that I linked to basically says that blowing a qfuse disables certain boot modes (fastboot), which I translate to mean locked bootloader. Dan Rosenberg did write the Loki exploit, and this may be part of, or a continuation of that work. In either case, I think I'm gonna start following Dan...a little closer. ;)

Sorry ibub.... got busy dealing with the bootloop also a Kindle Fire HD toasted and a LG Lucid toasted....grrrrr.....

Anyway

1.rooted phone with towelroot all was great.

2. Uninstalled bloatware with root app delete all was great.

3. Installed all my favorite apps all was great.

4. Decided to be a smart+++ and be the first to find a recovery for this thing and flashed a CWM recovery for another phone ( sorry I can not remember for what phone ).

Phone rebooted into a bootloop.

I can 'briefly' ADB to the phone but SU picks up the connection and CMD tells me I am unauthorized.... About as far as I get.... bootloop. :eek:

Edit::.. No I can not boot into safemode =(
[Android Q&A, Help & Troubleshooting] ibub:
Yeah, as far as I can figure, the bootloader verifies and loads the kernel, which in turn verifies nearly everything else(recovery, laf, some of the system, etc). But without system boot, can't authorize adb (unless previously allowed). And without adb or fastboot, we're lost. Try looking back through the thread. There have been some successful methods (pull battery and short the center two terminals on the phone to clear memory. Then try to safe boot, or regular boot. Grandkids? I thought I was the only old geezer on this forum. :)

While OUDHS can not work on every device, we do try to at least provide root and a custom recovery so that others may pick the ball up and run with it from there."

Over at Android Forums, they are talking about a Russian-sourced CM11 rom for the L70. The most interesting comment in the thread is comment #25, which says "So the source was for the w3 aka lg L40 but I think it works for the w5 tho with a few changes." Thus, the rom is based on sources for the L40, a.k.a. the retail equivalent version of the the TracFone L34C. Maybe this can help efforts for the Optimus Fuel, too???

Here's a Chinese forum that supposedly offers the official Verizon LG Optimus Zone 2 firmware, but you have to register. Nonetheless, maybe this means a kang'ed/debloated version is a possibility???

Gonna call LG and tell them I forgot my pin and need to hard reset the phone. In the instruction manual it says to press and hold both the power and down volume, then wait till the LG logo comes up then release the power,then press the power again within 3 seconds to get into it. Then choose factory reset with the volume up down then press power to confirm.

I haven't been able to reach that yet it just loops or it loads os with safe mode in the lower left corner.

Might make a good argument for telling them we need access or a replacement phone if we can't reset the phone outside of the Os.
