I will to translate this post summarized to english although my english is poor. Sorry but I don’t contol the past tense verbs :/

Yesterday was a “frenetic” day, as says Cachorro, a companion in www.clublgmobile.com forum.

In the morning I were noticied about new firmware for Korean KH5200 device that included Android 1.6. KH5200 is the same device that GW620, has the same hardware, but is distributed with this name. I downloaded the firmware to work on it.

The firs step was extract a backup from my device. Then plug in the device to the PC and I did the update.

At start the device get Korean language automatically, you can select other languages but only UK english, US english or Korean.

I download the usb drivers from LG from:

http://octopusbox.com/files/drivers/LGUSBModemDriver_WHQL_ML_Ver_4.9.4_All.exe

I plug in the device and it was recognized. Then I activated the Debuging Mode and the PC don´t recognized it. I went to Device administrator and I can see that the hardware id isn’t the same as GW620, I update my android_winsub.inf with it USB\VID_1004&PID_618E&REV_0100&MI_05 and the PC recognized it.

I had access to the device via adb, but not total access, I hadn’t root access. I press 3845#*620# to enter in hidden menu, but didn’t work. Of course, I have a KH5200 phone now, I tried with 3845#*5200# and then it worked. I went to Module test->Stability Test->Enable root permissions and … as I thought, the device ask me for the password, the same thing as V10I and V10N versions.

Some days ago, I try to install V10I version under rooted V10G and I could see that the root access remained. The V10G to V10I update don´t delete userdata partition and then I could see that the root access flag was in userdata. But the problem persisted due to the Korean V10M update erase userdata partition, … Then I thought to do this steps:

1) Extract system and boot images from the korean version.

2) Install GW620 V10G firmware version.

3) Enable Root permissions on V10G.

4) Access to fastboot and flash system and boot images from korean version.

I would have root permissions enabled with this steps. But unfortunately, I couldn’t do the first step. I needed root permissions for extract images.

I started to get nervous, and I started to remember the mother of the engineer that had the good idea of ask for a password. I thought: “I have to found the password”

I searched in Inet, but I don’t found. I searched the apk of hidden menú in /system/app and I found it. I extracted it to my PC and opened it with an hex editor, but I didn’t find the pass. Then I remenber that I see a disassembler of dalvik opcodes. I searched it on Inet and I found. I extracted classes.dex file from apk and I did disassembly it. Then I found the needed password , yeah!!

I had root permissions.

Then I searched by a method to translate the OS to spanish, then I found an application called “MoreLocale 2″, I istalled it, selected Spanish and it’s works, I extracted libicudata.so from other ROM with all languages and put it on my GW620.

Then I discovered (after a complete day) that I hadn’t coverage, I went to Setttings->Wireless controls->Mobile Network settings->Network operators->Search networks, select my network from my operators and I got this message: “Your SIM card does not allow a connection to this network”. I don´t know why. I think that is restricted to KT korean operator. I have search the way to connect with my operator but I didn’t find.

Then I saw that Android Wify tether doesn’t work, no NetFilter on kernel. Medieval Bluetooth FTP neither, no OBEX on kernel…

The last step in this day was try to enter in fastmode, I got a surprise, I could access to fastmode:

1) Extract the battery.

2) Put it again.

3) Press power button.

4) Wait 0.5 seconds

5) Press space repeatedly.

PD: You can’t access to fastboot mode if you have open I, N versions or Corean K. I have accessed to fastboot in Coran version, but it’s due to something that I have changed, I don’t sure but I think that is for rooting the system or due to activate “ro.debuggable” property which I have changed in my ROM. When I will be sure I tell you.
