[Q] No Download mode, no fastboot mode, no hard reset mode topic

Dear all,

Thanks for reading this post first. I have a G3 D855 with a unknown ROM inside (as i bought it from others, i don't know what the ROM is, but it is obviously a custom ROM). I try to flash a stock ROM and search the method from the net, but no method i can use for the following reasons:

1. i can't go into download mode (tried turn off phone, hold volume+ and plug in cable method)
2. i can't go into recovery mode with any key combination (used the method online, the screen will light up but LG logo won't show, there light off, keep looping like this)
3. i can't hard reset with any key combination
4. as you can see above, i can't get into fastboot mode with any key combination (but i do can use program in Win7 to call the phone into fastboot mode)
5. When i connect the phone (turned on) with Windows 7, it can recognised as LG G3, and i can explore the internal storage. But if i try to connect it for the Download Mode, then it can't be recognised, just "dang dang" sound from the computer. (i have installed the latest LG drivers). My phone can't be recognised in Ubuntu.

So, i try to figure out what has happened to my phone, and after searching for few days, i believe that i may flash sbl1.img, aboot.img, rpm.img, tz.img to get back the above modes for my phone (see http://forum.xda-developers.com/show....php?t=2582142). I would like to know if my thought is correct at this point.

If yes, can i just make my phone into fastboot mode with the help of the Windows Program to flash back those img, or can i use Flashify to flash those image?

Thanks for all your help.:)

[Q] Stock boot.img to flash via fastboot topic

Hi,
i have a Z1C with rooted stock-rom 14.2.a.1.142 (Android 4.3) and Recovery from DoomLord (CWM).
i tried to make a system-Upgrade, but it fails in cwm with error "failed to mount .../update_package". The file is present in this location, but i can't manually mount this "image".
searching about this message says me, that the flashmode can't be entered, seems that boot.img with cwm overrides that. now i search a stock-recovery/kernel with this mode to upgrade regularly.

i found also this thread: http://forum.xda-developers.com/show....php?t=2699858
and coverted the kernel.sin (9,9MB) with actual flashtool (linux) to kernel.elf (also 9,9MB). I tried to flash it, but get error that its not a valid boot-image. the boot.img from DoomLord ist 21MB

a direct flash via flashtool seems not possible because i cannot enter flashmode

regards Frank

Fastboot issue topic

Just got my N9 today. When I ADB devices, i see the serial # of my device properly. If I go into bootloader, when I fastboot devices, it comes up as all question marks (??????????????? fastboot). Windows properly sees my device as "Android Bootloader Interface". I am able to do basic commands (oem unlock, reboot-bootloader, etc). However I cannot push any files (root or custom recovery.) My DOS window just hangs and nothing transfers.

I googled for three hours and can't find if this is fixable or if I have to RMA. (And if I do RMA, how would I? I can't say I am having issues pushing custom recoveries to the device LOL)

Thanks in advance! :D

[Q] Lost fastboot access topic

Last night I unlocked the bootloader of my lte tablet running 2.1. Since unlocking it I lost fastboot access in bootloader. I tried everything I can think of, reinstalling naked fastboot drivers in both android and bootloader after purging anything resembling old drivers and alternatively tried getting fastboot access on a macbook and Linux laptop. In all cases my shield is recognised by adb while in android, but not after the reboot bootloader command. It seems so unlikely I broke fastboot access after a successful unlock, I hope someone can offer some ideas of what could be going on.

Thanks a million!

[Q] Using fastboot -c topic

Hello everybody. I need help figuring out what command line configuration to put inside of the parentheses of

Code:

---

fastboot -c "    "

---

How can I find out what command line to put in so that I can use

Code:

---

fastboot boot

---

Apparently since Android 4.4 you can no longer simply do the command

Code:

---

fastboot boot img.mg

---

and you have to do it something like

Code:

---

fastboot -c "console=ttyHSL0,115200,n8 androidboot.hardware=mako lge.kcal=0|0|0|x" img.img

---

or

Code:

---

fastboot -c "lge.kcal=0|0|0|x" boot img.img

---

or else it won't boot. The above commands work for the nexus 4. I do not have the source for my device but I do have the boot.img and zimage. I need this info to help me root the HD6!

[Q] How to Get Into Fastboot? topic

Hello,
I'm trying to get back into fastboot mode...my device is a d415, and I have already successfully installed a custom recovery and a custom ROM. However, I want to get back into fastboot mode and I can't figure out how. I zeroed out my laf partition again thinking that would do the trick - but anything I try either boots me into recovery mode or just turns the phone on like normal. Any suggestions for how to get into fastboot? Preferably a way where I can still get into Download mode/recovery mode?

Fastboot not working!?!? topic

So I managed to install the adb drivers for my OPO and then used the OPO Toolkit to reboot into fastboot mode. But the phone just shows a black screen. I tried manually booting into fastboot but it doesnt work. Just shows a black screen, windows detects something but seems like it gets disconnected immediately. The cable is working fine, I checked that already.

I unplugged the cable and booted into fastboot manually and it works but as soon as I plug the cable back in, the phone just shuts down I think and returns to the black screen. I tried searching but couldnt find a solution. Any idea where I'm going wrong? :confused:

PS: Now I think my phone is stuck in a bootloop at the bootscreen :crying:

[Q] No fastboot menu on Atrix (when pressing power on and vol down) topic

Hello,

I've searched for an answer but no luck as yet, hence posting.

I am following the instructions to flash CM onto my Atrix using an Xubuntu computer. However, I cannot get into the 'fastboot' menu on the device itself (pressing Power on + Vol down). I have a YouTube video of the problem, but I can't post links to external sites as less than 10 posts.

Incidentally, pressing Power on + Vol up does take me to the correct 'Starting RSD protocol support' menu.

Here's the instructions that I've been following:

Quote:

Unlocking the Bootloader with sbf_flash (Linux & OS X) You will need fastboot on the computer to unlock the bootloader of the Motorola Atrix 4G. Follow the Android SDK guide, to get fastboot on the computer. Download sbf_flash and the appropriate unlockable bootloader: sbf_flash: Download AT&T Atrix 4G Only: Unlockable Bootloader: Download md5: a5da47565160e0f95b84a1e769b9028b International Variants Only: Unlockable Bootloader: Download md5: f609dbc4c5842f9654e44a1980375100 Unzip the sbf_flash zipfile. Unzip the bootloader and place it somewhere easy to access. Power off the Motorola Atrix 4G. Boot into RSD Protocol Mode by holding down Up Volume and the Power button. Connect the Motorola Atrix 4G to the computer via USB. On the computer, open terminal and run the following commands: chmod +x sbf_flash ./sbf_flash <SBF File name here>.sbf It should take a few minutes to flash the unlockable bootloader, and the device may reboot multiple times. Once RSD lite reports that it's finished (or appears to be waiting for the device even though the device is booting into android), the device should be powered off. Pull the battery and power back on while holding the Volume Down button. Once you see the bootloader screen with some text options, cycle through the options using the Volume Down and select "Fastboot Protocol". If your device has "fail to boot" message, try to pull the battery and power back on while holding the Volume Up button.<<< This is where the problem occurs

(STUCK) Kindle goes into "fastboot mode" screen even when entering recovery topic

Yesterday was my first time rooting a Kindle Fire, and the root process went very smoothly when I followed this guide which uses saferoot: http://forum.xda-developers.com/kind...6-3-3-t2814955

While I made use of this guide for flashing FFF and TWRP: http://forum.xda-developers.com/show...13&postcount=3

After successfully rooting it, I wanted to try the OtterX ROM/TWRP/Bootloader, since I read the comments and saw it would be good to try it out. After flashing the bootloader (otterx-u-boot_v2.05), the kindle kept rebooting showing the logo and the option to 'press power to enter boot menu'. I thought this was normal so I didn't mind it. (During this time, I could still enter recovery.) I proceeded to Step 2 which was flashing TWRP for OtterX (I downloaded zip-otterx-twrp-2.8.2.0-recovery.zip and installed it using the previous TWRP I flashed: openrecovery-twrp-2.2.2.1-blaze.img).

I wasn't able to remember what I did next, but I know I was already having issues. I was getting anxious and sleepy at the same time, I remember exploring the boot menu and foolishly/stupidly tried the EMMC Corruption Fix, without even trying to research about it beforehand, so now I'm stuck at the "fastboot mode" screen (I've attached a photo of the screen). Whenever I turn on the device, it shows the kindle fire logo and the option to enter boot menu. If I let it be for a while, it goes into the "fastboot mode" screen, the same thing happens when I try to choose "continue boot" or "recovery boot". Windows doesn't recognize it anymore whenever I try to connect it too (I'm using Windows 8.1 by the way.)

Please help, I've tried reading about how I could restore the kindle to the state it used to be after I rooted it, but no luck, I couldn't find anyone encountering the same problem as me since I think I'm the only one stupid enough to apply that EMMC corruption fix without knowing or reading what it actually does. Thanks in advance to anyone who could help.
