Hi, I have a XT1635-03 and have an issue of power on button go to bootloader mode instead of go to system. Phone is unlocked and on modified logo.bin. Any idea how to fix this symptom?
Thank you.
Hi,
First boot to twrp recovery menu and connect your phone via usb. And in your computer open the adb fastboot command And type the following:
adb shell dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
#but do a backup before! (just in case)
adb pull /dev/block/platform/msm_sdcc.1/by-name/misc misc.img

Thank you, but I'm currently on stock ROM (retcn).
So I have to flash TWRP, perform the 'dd' command and flash back the stock ROM and the issue will be gone?
Update: Flashed the TWRP and tried the 'dd', it returned error of no such file or directory.
dd: can't open '/dev/block/platform/msm_sdcc.1/by-name/misc': No such file or directory
Cheers.

Here is the process
adb shell
cd cache
mkdir recovery
cd /
cp /sdcard/log /cache/recovery/
cp /sdcard/last_log /cache/recovery/
dd if=/sdcard/updaterecovery.img of=/dev/block/platform/mmci-omap-hs.1/by-name/recovery
idme bootmode 0x5001
reboot
The cp command doesn't work on windows, IDK why but thats how it is, i figured I substitute cat /mnt/sdcard instead of cp/sdcard, but again dd command doesn't work even with /mnt/sdcard. Can someone please help me through the rest of the process? And no i don't have linux/mac computers.
Here are the rest of the steps
Now in recovery, you will see that the first option highlighted, is Install update.zip from sdcard. Press the Power button (ok).
When prompted to install, press the Power button again. The recovery is modded because it can’t be navigated through right now. No here is actually Yes so just select that.
Once the ROM is flashed, without rebooting your phone, open up command prompt or terminal and navigate to the location where the stock recovery is.
Now enter the following commands:
adb shell
mount sdcard
exit
adb push/sbin/
dd if=/sbin/stockrecovery.img of=/dev/block/platform/mmci-omap-hs.1/by-name/recovery
adb reboot
The device will reboot twice now, and once it’s done, the CM7 logo will appear. For updates and queries,
It's simple install Ubuntu in windows using wubi .... It installs like a program and then u boot into it ... Don't be afraid of a penguin ....
You may just fall in love with a real operating system and check out mint ... Too

i believe you are missing a "su" command after adb shell
Yeah....you need adb shell, then SU to make the prompt go from $ to #. Try the commands then. They all work in win7, as I did it last night....three or four times.

Wrong forum!!!
I am stuck on:
Now enter the following commands:
adb shell
mount sdcard
exit
adb push/sbin/
dd if=/sbin/stockrecovery.img of=/dev/block/platform/mmci-omap-hs.1/by-name/recovery
adb reboot
it just wont mount the sdcard says its busy, nevermind i rebooted and it worked.
But now i am stuck on the sbin part, i must be missing something
Ok, once again nevermind, i just modified the first recovery command to:
dd if=/sdcard/stockrecovery.img of=/dev/block/platform/mmci-omap-hs.1/by-name/recovery
and it worked out at cm7 boot anim right now.
Try "ADB shell" then "Su" then "Mount /sdcard"
Minus the " "

I would like to try flashing the stock bell rom back on my phone but I never backed it up initially.
I've been having Bluetooth music issues with both kernelpanics and ho!no!s roms so I have to get stock to test if its the phone or just the roms while its still in warranty.
Thanks guys!!

What are the ADB commands to flash the file to my phone?
Bump for new topic. Found System.img of stock bell canada rom

Okay, first, in CWM, you don't need to su for root permissions, your ADB shell has them. Second, if you haven't copied your file to the root level of your sdcard and if your file isn't named "system.img" exactly, that command will fail. I'll leave it to you to figure out how to move/rename your system.img file accordingly lol
Edit, it just occurred to me you might be having the garbled sdcard problem where it will spit out garbage if you type in the "ls" command in ADB. The solution has been posted by kernelpan1c, but first let us know what the output of ls is if you're sure your system.img is in the root level of your sdcard.

I already used ADB to push system.img to my phone's SDCard root directory.
Are you suggesting that I reformat my SDCard through windows?
I just realized that I am lacking the boot.img of the stock bell ROM. system and boot are the two that are absolutely necessary to get the phone working correct?
Which rom are you coming from? If it's a Nitro rom/kernelpan1c's rom, you shouldn't have to flash boot.img.
Yeah, according to kernelpan1c, there is something weird going on with the way our sdcard is formatted. After formatting it in Windows he says it should work just fine in the CWM flashed by Rom Manager (I haven't tested it myself, but I'm sure he's correct). I really want to know what is making the Rom Manager CWM unable to read it where bytecode64's CWM can read it just fine...

I think I'll be using HO!NO!'s rom as a base for the boot.img, since he has a bell optimus LTE, not the AT&T phone. I'm assuming that he hasn't made any changes to the boot partition, since no custom kernel development has occurred for this phone yet.
I found a so called legit CWM backup of the BELL rom, in one of the lu6200 threads, http://forum.xda-developers.com/showthread.php?t=1472501
but recovering the backup only hangs on the LG logo. I did a "advanced restore" and restored only the system and boot files but that didn't get past the logo either...
It booted after an advanced restore with the "stock" system(from that thread) and the boot (from HONO's), but the WIFI wouldn't start, it said error.
Where did you get your stock bell system.img? and can you provide it?

Mount sdcard in recovery.
After you enter adb shell
"mount /sdcard" (without quotations)
Then use the command "dd if=/sdcard/system.img of=/dev/block/mmcblk0p27"
Here is a link to the .img files. You can flash them using adb, but you will lose CWM. I am posting these in the hope that it will help someone who knows a little bit more about bootloader security and whatnot to make a CWM-compatible version.
The stock files are Here
Extract files to root of SD card, enable USB debugging and PC Software mode (if on LG rom)
Run the following from windows command prompt:
adb shell
su
dd if=/sdcard/boot.img of=/dev/block/mmcblk0p8
dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p13
dd if=/sdcard/firmware.img of=/dev/block/mmcblk0p1
dd if=/sdcard/baseband.img of=/dev/block/mmcblk0p14
dd if=/sdcard/system.img of=/dev/block/mmcblk0p27
Restart,
Congrats, you've got the latest Bell release for the P930.

Used Rom Manager to install CWM.
Whenever I try to boot into CWM, i get the following error:

The ROM boots though, and has root access. Superuser works, and I am currently using titanium backup to delete the massive amounts of bloatware present in the rom.
I have attempted to flash recovery.img with CWM on it, but the error persists.
Anyone have any ideas as to how we can get around this error?

You must downgrade to GB before you can install CWM properly.
I just wonder if it works if you just load boot.img and system.img with adb.

You're welcome to try. I am too busy today, and I have started getting random reboots, so I'm switching back to Liquid Nitro.
[EDIT] - adb commands work fine..
I am rooted and bootloader unlocked, trying to flash back to the stock kernel. I can boot into bootloader (fastboot mode), however when I issue the fastboot command from my pc, nothing happens like the usb connection is not recognized.
"fastboot devices" does nothing.
C:\Program Files (x86)\Android\android-sdk\platform-tools>fastboot flash boot boot.img
< waiting for device >
Is fastboot supposed to work?
Alternatively is there a recovery package somewhere that includes only the current stock kernel?
Thank you for your help.
You can actually use my all in one in the dev section to do it for you.

Shadow, thank you for your work! I jumped into your github to check out the code because I am not sure if the boot.img your app is downloading is the latest zv9 release kernel.
It looks like I can
1) drop boot.img into /sdcard/
2)issue the following from terminal on device (or from adb):
su -c dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/boot
su -c dd if=/sdcard/boot.img of=/dev/block/platform/msm_sdcc.1/by-name/boot
3) rm /sdcard/boot.img
4) reboot
EDIT: This worked great issuing commands in adb shell (grant su on the phone when it pops up)
THANKS!
Now I need to figure out how to get fastboot communicating
Guys please help me, i need laf.img, i lost my download mode
just do this for me:
adb shell # open a shell over adb

exit # exit the superuser shell
exit # exit the adb shell
adb pull /storage/external_SD/stock-recovery.img . # backup the recovery image from you external sd to the PC
