Fastboot for Grand X

[Guest kliskobg]

Hi all,

I am trying to test CWM but don't know how to get into fastboot mode. When I try adb reboot bootloader, I get nothing - phone reboots into normal (user) mode. Powering on with VOL- doesn't boot the phone, red LED lights up, the screen remains blank but fastboot devices does not give any response.

After rooting the phone, I made dd copy of system (/dev/block/mmcblk0p3), boot (/dev/block/mmcblk0p2) and recovery (/dev/block/mmcblk0p1) partitions but I am not sure if that is enough to have a safe backup. Any suggestions on that?

I built CWM with recovery builder (from stock recovery I pulled out) and would like to boot into it without flashing it (using fastboot boot recovery.img). Do I need to use NVFlash or what? Anyone knows if the bootloader is locked? How can I check if it is (without bricking the phone :D )?

For those who are more familiar with these things, below is partitions layout. Is there is any other interesting info to pull from the phone so more knowledgeable people can give us hints how to get recovery ported for this phone?

Google found for me that following are mappings into androind partitions

 APP -> system

LNX -> boot.img

MDA -> Unknown

MSC -> Misc (bootloader commands and other misc stuff )

PER -> usually a fat partition containing sensor calibration etc. - per device provisioned.

SOS -> recovery.img

UDA -> /data - "user data area"

USP -> Staging

Yay! I wish I could help but I am just gonna thank you for at least trying to develop custom recovery!

[Guest tillaz]

is the bootloader not locked on this device

[Guest kliskobg]

I don't know. How can I check if it is locked?

[Guest tillaz]

I don't know. How can I check if it is locked?

not been able to get into bootloader mode might be a sign its locked,

best guy to ask about what you are doing is seb > http://www.modaco.co...8-sebastian404/

maybe ask him if can take a look at your thread

[Guest CoaBalboa]

Can anyone check this? http://jenkins.cyanogenmod.com/job/recovery/7088/ Some one compile it and posted on one Serbian forum that is for Grand X, but no one has try it. Me neither.

[Guest kliskobg]

I uploaded the stock recovery to recovery builder which generated CWM from the link in CoaBalboa's post. I'd like to try to boot into it without flashing it the phone but haven't been able to do so. If any one can help, I am open for suggestions.

From what I learned, LG O2X is also tegra 2 based so I tried to get into APX mode following this thread but nothing really happens when I connect the phone to PC. I am out of ideas what to do, so I'll go with what tillaz has suggested and PM Sebastian404. Tillaz, thanks for the tip.

edit: cannot send PM to Sebastian404 :(

according to Chinese version of xda forums, root & recovery are achieved

Willing to try, but seem that recovery are all in Chinese.

Maybe someone can translate in english

Downloaded files, and uploaded here

Files included:

zteU970_Tools.exe (another root method)

recovery-off-open-adb.img

Instructions are on Cninese XDA site (use Goggle translate)

[Guest tillaz]

look here, he has a tut for clockworkmod on the zte v970 (grand x)

it might not work with the tegra 2 versions though

[Guest CoaBalboa]

Someone need to test it...

edit:

copied from topic:

i just figured that i have a phone with Tegra chipset, so can't use your ROM

This is where we should look, Chinese u970 is almost identical to ours Grand X, it have tegra but stock clocked at 1,2ghz and 1gb of ram.

There is even a MIUI version for U970 with instruction on how to root & install it from recovery, but all is in Chinese and I don't know if its safe to do it on our Grand X, if there would be any hardware issues because of its differences.

Miui for U970

trying to dump system and boot.img, but get error: permission denied

but adb pull /system working

[Guest bartasrex]

tried to flash the recovery from MIUI site but when i booted to it there is no back light and i can only navigate by pressing down the - vol key, but i cant enter any option, pressing power button to chose does nothing. could anyone provide a stock recovery form his phone so i can flash it?

[Guest killar_aka_arabu]

here Download

p.s. this is just rar archive with recovery what i adb pulled from my stock rom.

can you provide link to site where you downloaded custom recovery?

i have translated the tools which was provided on the miui site and uploaded them here

could you help me with it? how can i push it to my phone?

[Guest killar_aka_arabu]

there are thread with stock rom

download it and put to sdcard

then turn off the phone and conect to usb cable

when phone showing charging battery, open cmd and locate adb files, then type

adb reboot recovery

then apply update from sdcard and choose file

[Guest bartasrex]

but as i said, my recovery is kind of broken, after i flashed the one i have downloaded from miui site. i'm not able to choose any option;/

[Guest killar_aka_arabu]

try this with adb

adb shell

su

dd if=/sdcard/recovery-from-boot.p of=/dev/block/mmcblk0p1

[Guest bartasrex]

did as you said and now it wont even boot to recovery. good thing is that system is still working, phone is booting and is fully usable, but without recovery i cant install anything and do factory reset;/

[Guest killar_aka_arabu]

try this:

flash again custom recovery from MIUI

boot phone and

go to settings - about phone - software update - update from sd-card

[Guest bartasrex]

this isn't working too, my version is form uk, and the system is named GEN_UK_GRANDX1.0.0B02, mayby i should find a system for uk device?

i have the following information after trying to flash this rom you provided:

failed to verify the whole-file signature

signature verification failed

installation aborted

Edited October 14, 2012 by bartasrex

[Guest killar_aka_arabu]

just now i have verified zte support from UK, and unluckelly, they not provide Downloads for this device(((

only russian support have alvaiable downloads for this device(

meybe try to unpack only build.prop file from /system folder, open in notepad and change this -> GEN_AP_P943HV1.0.0B10 to this -> GEN_UK_GRANDX1.0.0B02

save and put it back in archive to /system folder (delete old build.prop and paste new)

Edited October 14, 2012 by killar_aka_arabu

[Guest killar_aka_arabu]

i have translated the tools which was provided on the miui site and uploaded them here

this is for zte u970 (with 1.2Ghz processor, 8mpx camera and 1gb ram), but too is tegra 2.

[Guest kliskobg]

bartasrex, here you can find recovery I pulled from my phone (mine is not from UK either, look at my location):

http://jenkins.cyano.../recovery/7088/

inputrecovery.img should be the original one, while recovery.img is supposed to be CWM recovery build based on factory recovery. I have't tried flashing any of these back to my phone.
