Let keep my finger crossed

I was trying to upgrade my ROM to 2.3.4

Then I received good news that I got an Interview

While trying, I go back to HOT HD9
and download
HD9 Android 2.2 V6.1MOD by BM.7z (70,925 KB)  




The HD9 went die


I quickly change USB port and tried original ROM
but again I noticed the original ROM has too big of system.img file that it keep failed

I have went through many times from heaven to hell and back heaven


When I finally get back HD9_2.2.1
I was again relieved

Well at least I was not going to be forced to buy THL  V9 next week ...

Now I have to try out the different ROM in a slower pace ...

After I use CWM v4.0.0.5 and restore back to my original ROM dated this monday

Each time, like a ritual, I will take out the battery and put back again

Then I switch on the handphone

After few exercise , I still struck with my original ROM

But my wish is to start with a simple ROM with tethering hotspot

but version 2.2 show it has

http://en.wikipedia.org/wiki/Android_version_history

v2.2

On 20 May 2010, the Android 2.2 (Froyo) SDK was released, based on Linux kernel 2.6.32.^[27][28] Its features included:^[27]

• 
  
• USB tethering and Wi-Fi hotspot functionality

But anyway, let check out for other options 


Now the mobile is back working ... that is the relieve ! 

HD9 2.3.4 ROM

This morning I tried to change to HD 2.3.4 ROM

Few things bother me
there is no secro img ?

Is there a CH2.3.4.zip file and can it be done via zip file ?

Half way the data connection loss
(I was doing something at the same time ...)

I tried to flash 2.2.1 ROM but USB connection lost

So I press vol up for recovery mode
(luckily I did not change the recovery img )

Blessing by disguise
I do a recovery and it prove work
This is what YS wanted too
It is just like a Norton ghost on PC
everything is restored back to normal
with even the IMEI installed

I will try again after lunch time

Why can not login Google via 3 G

It has been a while after trying with few devices that I realize that
I Must login to google account via WiFi

Even for CS Lai as he keep complainting that he can not login google gmail
each time he change the SIM cards

I have not research on Internet yet
but it seem to be a practice to do so

HD9 2.2.1 ROM

I have loaded this ROM two days ago
as it is the simplest

Few things I may not appreciate as it lack of tether hotspot
I need this Foyo feature a lot of time
For example to login google via wifi

Even this ROM take off gmail completely

The hacker keyboard give me the most headache as it does have Chinese inpu

Finally again I have successfully flash_tool recovery to my Chang Jiang HD9 !!

If following through the thread, although very messy

I was not able to use the flash_tool to flash the HD9

I keep question about the process of the 3 interfaces

Adroid ADB interface

Adroid bootloader interface

Adroid Composite ADB interface

I even post the query on 

http://products.mobileuncle.com/viewthread.php?tid=115548&highlight=%CE%D2%D3%D0MT6516

I tried to down other windows versions too (even for win98 version) from mobile uncle

and I even thinking to use the old windows XP computer at home too

Then I reload the interfaces again

I turn off the HD9 and load a new driver

I purposely choose the Adroid bootloader interface

I load win XP driver (but I not sure ... )

Then suddenly the flash tool works !

(It was a shock as I have flash tool multiple times before that

almost two cycles of switch on and off the HD9

as I also read that the Hd9 battery must be take on and put back)

http://products.mobileuncle.com/viewthread.php?tid=93885&highlight=HD9

I was lucky to load the CWM recovery 4.0.0.8 too

So immediately I go to backup and download

http://www.4shared.com/dir/5nPtvIuJ/_online.html#dir=225928852

However, after I have boot up HD9

and tried to link up with MyPhoneExplorer

MPE fails to connect as win_usb fails to work now

So I have to wait to see if there is other methods or explanations

for the time being I dun use MPE on HD9 ...

All versions of CWM

Take note it is for

• LG Optimus 2x
• Optimus 2x Android Development

From
http://forum.xda-developers.com/showthread.php?t=1098745

I found a good download place for all versions of CWM

http://www.mediafire.com/?gtj2fms2edid5#s1svbbb2c00rr

Hopefully will find one version that will work for my HD9
then I can do for viewpad then ACE
and future hps and tablets

What Is Bootloader And How To Unlock Bootloader On Android Phones [Complete Guide]

http://www.addictivetips.com/mobile/what-is-bootloader-and-how-to-unlock-bootloader-on-android-phones-complete-guide/

I was not able to boot into recovery mode in HD9

Maybe the manufacture lock the bootloader as they know I am trying to break into it

got adb shell root prompt #

I got the answer to get root on adb shell as in

C:\MTK\downloads\IMEI>adb shell

* daemon not running. starting it now on port 5037 *

* daemon started successfully *

$ su

su

http://www.droidforums.net/forum/droid-hacks/14605-adb-shell-su-permission-denied-rooted-phone.html

Make sure the phone is on and unlocked when you try to run "su" and a window will pop up asking you to allow it to run, check for it to remember, then allow.

----------

is usb debugging mode on? and when u do su it usually pops the allow. i had this problem before so yea.

----------

Yes...they figured it out. read above. You have to answer Yes on the phone to allow access to root. Make sure you check the box below it that says do you want to allow it every time and then you won't have to answer that again...until you flash another rom and wipe all your cache that is.

----------

So under the USB debugging mode , I check on Stay awake

and it works

as previously

I am using Z4root to root the HD9

However, I keep suspect HD9 is not fully root as I do 

C:\Program Files\Android\android-sdk\platform-tools>adb shell

adb server is out of date.  killing...

* daemon started successfully *

$ su

su

Permission denied

$

My last rooting of viewpad 7 using superclick

I was able to got the root # prompt

however, I did run the root checker

and it report HD9 is fully rooted

It take me a while to translate Russia website

and finally found the HD9

As mentioned, in GuanZhou there is another vendor (CJ hp battery vendor THL)

got a shop selling V8 at 999 RMB (same as V7 and it has own flagship shop)

http://www.thl168.com/products_detail/&productId=20.html

In summary CJ HD9 / THL V8 is almost the same model
