E:Bad boot message

 

[asrhael]

Hello, im using the P500h cellphone with Entel PCS as my service phone provider.

Im tried to install this Custom Recovery, im follow all the step and type in the terminal using the "WiFi Keyboard apk" from Market, so the code its ok to my terminal (im avoid the #, i understand that i need to put "su" to get root permissions).

After copy/paste all the code (w/o the #), my device is self restarted and go to the Recovery mode, butttttt....my phone enter directly to "factory reset" (dont showme any menu) and showme the splash of the "box+droid+arrow"..after a couple of seconds, my phone is factory reseted

I have this issue from the beginnin, i press and hold the volumedown+home and then power on..after the LG logo appear, i release the keys and go inmediatly to the factory reset.

What happend with my LG P500h v10a?, what do not enter to the full recovery menu?.

Thanks a lot for any help. I want to make a nand backup for installing a custom rom (prime v2).


best regards,
asrhael

Guys, now everithing work fine for me :]

The problem was that i dont unziped both files. After unziped, run the commands in the Terminal with "WiFi Keyboard" apk from market (for avoiding any mistake) and my Custom Recovery was installed fine.

After that, im create a NAND backup and then installed the Prime V2 ROM for my P500.

Thanks a lot.

flash_image recovery /sdcard/recovery-RA-GNM-thunderg-1.1.0.img
permission denied
what do i do

 

[ravoyd36]

The recovery boot worked only on the immediate boot after typing the code. Its not opening now. And the flash image and the thunder-1.1.0 zip did not work when I tried to install it. It said " verification failed" and "installing aborted ". Nand and recovery worked though.

i got the same problem. What to do?

 

[ravoyd36]

The flash_image zip and the thunderg zip failed to install as they didn't find an update script. Can anyone tell me what this means? And I installed Megatron and a kernel nevertheless and all my data, cache and apps are gone and gprs isn't working anymore. My phone is much faster though. Can someone please help?

$ mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
mount: Operation not permitted


does anyone know why i get this error?

 

[jason0777]

when entering "cat /sdcard/flash_image > /system/bin/flash_image" i get invalid length! What might i be doing wrong? And do i want to have usb debugging on or off i have tried both?

 

[pwntigo]

Can't boot into recovery mode, every time I press power + vol down + home on poweroff phone it bassically wipes everything from the memory

 

[fuz2zy]

After typing in the command
# cat /sdcard/bin/flash_image > /system/bin/flash_image

I get
cannot create /system/bin/flash_image : read-only file system

I am unsure how to proceed after this.


Before this line, the line before
(# mount -o remount,rw -t yaffs2 / dev/block/mtdblock1 /system)
resulted in a reply
Usage: mount [-r] [-w] [-o options] [-t type] device directory

I assumed it to be correct and proceeded

Any help would be appreciated, thanks

Edit: Stupid mistake ==, copied flash and recovery images into sdcard, not sdcard/root

 

[theface08012]

i got all the steps down but when i get to the last line of the code i get a syntax error unexpected with "("

# flash_image recovery /sdcard/recovery-RA-GNM-thunderg-1.1.0.img

flash_image : 1: syntax error : "(" unexpected


any help would be greatly appriciated

Guys, how to paste the two image files to the SD card extracted from downloaded zip files? It always says cannot copy, write-protected, and access denied.

Please help..

Update:


Guys, there are several types of backup here:


- Nand backup
- Nand backup + .android _secure
- Nand backup + ext backup
- Nand backup + exter backup + .android_secure
- Backup Google proprietary sys


I have tried the "- Nand backup + exter backup + .android_secure" but it says run nandroid-mobile.sh recovery" from adb... . And so I tried the "Nand backup" only and it succesfully went through. Now I am bit confused why the first one(- Nand backup + exter backup + .android_secure) had an error...


Which is the best option of these backup?

# cat /sdcard/flash_image > /system/bin/flash_image

/sdcard/flash_image: No such file or directory

Yes I extracted it to the root folder of the sd card,

# mount -o remount,rw -t yaffs2 /dev/block/mtdblock1 /system
# cat /sdcard/flash_image > /system/bin/flash_image
/sdcard/flash_image: invalid length

Do not type the # . You have to do the su command 1st to call a root ie # shell. The $ shell is a user shell.

Hello guys,
I was just wondering whether there is a way to mount the sd card to your pc when in recovery mode. Also when I try to use adb to push a file I get an error saying that the device was not found, although it exists at the device manager. Any ideas?
Thanks in advance.

Thanks in advance.

Adb shell mount /sdcard or use gui mount menu (same effect as prior command) or ums to mount sdcard as mass storage.

 

[mihachris]

Thanks for your reply and congratulations for your work!
The problem is that the adb cannot find the device and I get an error. I also tried the other two options but none of them worked. I can see the phone to the device manager and I have USB drivers installed but I cannot access the sd card.
Do you have any suggestions?
