Fastboot for Grand X

47 posts in this topic

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?

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

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)

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.

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)

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.
