what gps and wifi chipsets has this phone? bmc rtl?
BCM4329 for wifi?
i am thinking in port boot-img of this other phone: http://forum.xda-developers.com/showthread.php?t=1045910.
This is the init script to load from sdcard:
/bin/sleep 5
mkdir -m 0755 /proc
mount -t proc proc /proc
mkdir -m 0755 /sys
mount -t sysfs sys /sys
#Configure Devices
MAKEDEVS
fail() {
echo "Failed"
echo "$1"d
exec /bin/sh
}
while [ ! -e /sys/block/mmcblk1 ] ; do
echo "Waiting for SD Card"
sleep 1
done
partition=mmcblk1p1
# Try unpartitioned card
if [ ! -e /sys/block/mmcblk1/$partition ] ; then
partition=mmcblk1
fi
mkdir -m 0777 /sdcard
echo "Checking SD card for errors"
dosfsck -y /dev/block/$partition
mount -t vfat -o fmask=0000,dmask=0000,rw,flush,noatime,nodiratime /dev/block/$partition /sdcard
[ $? -eq 0 ] || fail "Failed to mount the SD card. Cannot continue."
mkdir -m 0755 /rfs
if [ -e /sdcard/linux/rootfs.ext2 ] ; then
losetup /dev/block/loop2 /sdcard/linux/rootfs.ext2
[ $? -eq 0 ] || fail "Failed to find rootfs.img on SD Card. You need to unzip a rootfs zip file to the root of your SD card."
e2fsck -y /dev/block/loop2
mount -t ext2 -o noatime,nodiratime,sync,rw /dev/block/loop2 /rfs
[ $? -eq 0 ] || fail "Failed to mount /rootfs"
fi
umount -l /proc
umount -l /sys
echo "Switching to rootfs..."
exec switch_root /rfs /init
simply script. and this is MAKEDEVS script:

the more normal is that it differ for lg optimus black.
For launch ubuntu in lg optimus no need more. Only wifi drivers and touchscreen but we don´t know bcm driver. SGX drivers for 3d acceleration is offered in maverick 10.10. multitouch is possible that run with utouch driver. omap3 kernel images are ofered and it`s easy create img with rockstock and create ext2 file (http://androlinux.com/android-ubuntu-development/how-to-build-chroot-arm-ubuntu-images-for-android/)
source code of v10a is offered in the web of lg http://www.lg.com/global/support/opensource/opensource.jsp

bcm4329, correct.
And you're probably the only one who wants ubuntu on optimus black.
maybe i'm wrong, but i found this:
http://android.git.kernel.org/?p=pl...c;hb=f427424c414886903e4ad654c143c8ce6ec10e3c
and this:
http://www.mail-archive.com/[email protected]/msg09253.html
ok, then it ´s the driver:
1 Downloaded the modules from the link I posted earlier (direct link to the module you will need: http://www.mediafire.com/?mmaqtlr3k35bhol )
2. Mount the image on an ubuntu computer using the commands from the first post.
3. Overwrite the file in /lib/modules with this one
4. unmount and boot up ubuntu on your phone.
5. Open the wifi mode on your phone.
6. Connect your phone to your pc.
7. Cd to the androidsdk folder and type adb shell.
8. In the adb shell (it starts with # ) type cd /lib/modules
9. Type "insmod bcm4329.ko" (without the "").
10. Go back and connect to your favorite network.
11. Have fun!
only we needs one makedevs with the parameters correct.

it is one good experiment.
Hi everyone,
First of all - apologies if this is in the wrong forum. First time I post something, so not too sure if this is the right place.
I've been struggling with my Nexus 5 for the past 3 days after I attempted a factory reset. After trying everything I could find, I managed to combine some strategies from different threads, and got some help from a friend who is a linux specialist. As it has been REALLY HARD for me to fix this, I thought I would post the solution in case anyone is seeing the same issue.
Summary of my issue:
I attempted a factory reset to cleanup the phone. That was really all I intended to do.
The factory reset got stuck on "erasing". After 30 minutes waiting, I forced the phone to reboot. Then everything went downhill.
My Nexus 5 started bootlooping. It wouldn't even get in recovery mode.
I've flashed ClockWorkMod Recovery, and tried to format everything and start again. The processes to wipe partitions would fail.
Flashing stock also failed, as things would hang on "erasing cache".
I found references on multiple threads about things to try - from flashing other ROMs, to formatting the file system manually, and basically trying every step of a flashing a stock installation manually.
The bottom line is everything would hang because the system could not mount the /data partition.
When I tried to use "e2fsck" to check /userdata partition, it would give me an error about the file system being corrupted, and suggesting to use a different superblock.
Some threads here in XDA suggested to use CWM and TWRP to format the partition, as that would usually fix the problem. It didn't work in my case.
The system would basically hang when trying to format /data, with any method I tried.
When using the "dmesg" command, I would also see lots of errors with superblocks when trying to mount "/data".
I considered it could be a hardware issue, but I was not seeing problems with the other partitions (/cache, /system, /recovery, and so on).
Solution:
I fixed the problem by removing the partition, recreating it with "ext2" file system, then upgrading to "ext4" manually, and finally flashing the system images again WITHOUT flashing userdata.
Every time I flash "userdata", the partition just gets corrupted.
This is the step by step on how I did it:
1) Start the phone on bootloader by holding power button + volume down. Flash CWM recovery through fastboot.
Download CWM recovery from here: https://clockworkmod.com/rommanager
I'm using windows, so I opened a command prompt on the "Android SDK\platform-tools" folder.
run: "fastboot flash recovery <CWM_Recovery_Folder>\recovery-clockwork-6.0.4.5-hammerhead.img"
2) Reboot in recovery mode, so that it would load ADB. In the command prompt I ran "adb shell" so I could use the linux tools
Use "parted /dev/block/mmcblk0" to open the parted tool for the mmc block.
Use command "print" to list all partitions. You should see something like this:
Number Start End Size File system Name Flags
1 524kB 67.6MB 67.1MB fat16 modem
2 67.6MB 68.7MB 1049kB sbl1

28 2032MB 31.3GB 29.2GB ext4 userdata
29 31.3GB 31.3GB 5632B grow

Click to collapse
3) Remove the existing data partition by running command "rm 28" .
4) Recreate the partition and the file system with "mkpartfs". I didn't use all parameters at once, but just informed the proper values as requested by the tool:
(parted) mkpartfs
mkpartfs
mkpartfs
Partition name? []? userdate
userdate
userdate
File system type? [ext2]? ext2
ext2
ext2
Start? 2032MB
2032MB
2032MB
End? 31.3GB
31.3GB
31.3GB
Click to expand...
Click to collapse
5) The partition should now be recreated as "ext2" file system. I've set the partition name with:
(parted) name 28 userdata
name 28 userdata
name 28 userdata
Click to expand...
Click to collapse
If you print again, you should see the new partition as ext2 file system:
(...)
28 2032MB 31.3GB 29.2GB ext2 userdata
(...)
Click to expand...
Click to collapse
6) Upgrade the FS from ext2 to ext4 by using make_ext4fs:
make_ext4fs -l 29236371456 -b 4096 -g 32768 -i 8192 -I 256 -j 32768 -L msdos -a /data /dev/block/mmcblk0p28
Now here is the interesting part. When I tried to run "flash-all" from the google stock image, this is what I would see when it ran the format script on the userdata partition:
OKAY [ 13.186s]
formatting 'userdata' partition...
Creating filesystem with parameters:

sending 'userdata' (139109 KB)...

OKAY [ 16.625s]
finished. total time: 29.811s
Click to expand...
Click to collapse
When I manually ran the make_ext4fs, the only difference was I added a label "msdos" and this was the result:
Creating filesystem with parameters:
Size: 29236371456
Block size: 4096
Blocks per group: 32768
Inodes per group: 48
Inode size: 256
Journal blocks: 32768
Label: msdos
Blocks: 7137786
Block groups: 218
Reserved block group size: 1024
Click to expand...
Click to collapse
Almost the same thing, but with a difference in "Inodes per group": stock script shows 8192, and running manually it shows 48.
I have no idea why is that. Honestly I know very little about linux and its file systems, so I don't know what that means.
After I did this, I was FINALLY able to mount the "/data" partition.
8) Checked the file system with e2fsck. It now worked fine:
~ # e2fsck /dev/block/mmcblk0p28
e2fsck /dev/block/mmcblk0p28
e2fsck 1.41.14 (22-Dec-2010)
msdos: clean, 11/10464 files, 45158/7137786 blocks
~ #
9) Manually flash google stock system, cache, boot, and bootloader.
I was using this image: hammerhead-ktu84p-factory-35ea0277.tgz
I uncompressed this to a folder, and also uncompressed the image-hammerhead-ktu84p.zip.
So I ran:
fastboot flash system system.img
fastboot flash cache cache.img
fastboot flash boot boot.img
After this, I rebooted the system and it loaded, after loooooong 3 days reading through everything I could on XDA!
These were some of the threads that helped me in one way or another to get to this solution:

I really hope no one else had the same "luck" as I did, since this problem has been a nightmare.
But in case you unfortunately do... hope this helps!
Great guide. Might become handy for other users. It should be stickied
Why would you force reboot while factory resetting in the first place lol
Sent from my Nexus 5
Good guide but a bricked phone is rendered useless, hence the name 'bricked.' If your phone can still power on, it is not bricked. You said your self you got it out of a bootloop. That's essentially all you had, a bootloop, and you were able to figure out what was wrong with it.
Just a heads up so we don't throw that term around loosely since a lot of people do so.
You can't bring a phone back from a brick. I think JTAG is an option but its for Samsung phones only. (Feel free to correct me if I'm wrong.)

Yeap, I know it sounds stupid but the factory reset was hanging, lol.
I tried multiple times and it would hang every time. I left it running for more than 3h once and nothing happened.

Thanks for clarifying! I thought bricked also meant "the phone is about to go useless, but there is a tiny hope", lol.
Is there a way to correct the thread name?
You're right - it was only bootlooping.
There's soft-brick and hard-brick.

dont know how it got bricked..in morning when i wake up its suddenly start showing the boot only for hours. I've tried flashig it.evertime got flash write failure for bootloader and other images except boot.img .i've checked for emmc its fine and showing the device partion.
I'm using nexus 5 16gb device.pls anyone help
I assume the bootloader is unlocked since you are able to flash the boot.img. Try this: re-lock the bootloader, reboot to fastboot and see if the bootloader remains locked. If the bootloader unlocks itself, this is an indication that the memory chip is damaged. Also try flashing the older stock ROM available.

Try the suggestion about relocking there bootloader and checking to see if it stays locked. If it doesn't stay locked, I would replace the motherboard.
When trying to delete partition 28, I get:
Error: Input/output error during write on /dev/block/mmcblk0
Anybody else got this and found a way to solve it?

I assume the bootloader is unlocked since you are able to flash the boot.img. Try this: re-lock the bootloader, reboot to fastboot and see if the bootloader remains locked. If the bootloader unlocks itself, this is an indication that the memory chip is damaged. Also try flashing the older stock ROM available.

Thanks, I've been reading for quite some time looking for a solution to fix my Nexus 5 (I bought it brick just to fix it), and it does exactly what you mention here in your post. It recognize fastboot, it lock the bootloader but when the phone reboot, it display bootloader unlock. It doesn't let me flash the recovery img. by computer.
Thanks
The motherboard's flash memory is defective which means you'll need to replace the motherboard to have functional phone.
