[HELP] HTC Desire VC - accidentally formatted the /system folder with recovery mode - Android Q&A, Help & Troubleshooting

My HTC Desire VC (T328d) was rooted and running Android OS 4.0.3 (ics).
In recovery mode, I accidentally formatted /system folder (from internal phone memory).
This is because the recovery mode is all in chinese language and I did a huge mistake.
The phone cannot boot showing HTC logo screen and no boot sound.
I've downloaded the kernel for this device at htcdev.com and I don't know how to use it and what it is for.
Fortunately, I can enter recovery mode. My friend has the same device and his is not rooted yet. Maybe I can get some files from him.
Any solution, please?

There is no forum for my device. Only for Desire, Desire HD, Desire V ,.........

Looks like your best shot is to root your friends phone, do a nandroid backup, restore it to yours, then reset to factory defaults.
Don't forget to use V6 SuperCharger afterwards... lol

Thanks for your advice. But, I don't know how to do nandroid backup. The instructions say that it is apk app. I can't even boot my phone and how can I use apk ? In addition, now I installed a recovery from china site (for Desire VC specifically) and it contains backup and restore function. Is it the same with Nandroid Backup or CWM ?
Can you instruct me in some steps, please ?

Yes, the backup option you see in recovery is Nandroid backup. Please be carefull in formatting system, it would wipe your ROM. Always take nandroid backup before you playing with other Rom.
Here you go,
1. Take nandroid backup of your friends ROM
2. Place the backup into your sd card( backup available in clockwork folder in ur friends mobile. Just copy the entire clockwork folder and paste in ur sd card. Now mount the sdcard in ur mobile)
3. Reboot in recovery.
4. Wipe cache and dalvik
5. Restore from nandroid.
Let me know this helps..

Dalvik is virtual machine that runs Android Apps on Android. Dalvik-cache is the cache area for Dalvik VM, it is created when the Dalvik VM optimizes your app for running.
Dalvik is the virtual machine that is used by Android. It is generally thought of as a java virtual machine, although this is not precisely correct. It uses an object model that is identical to java, and it's memory model is also nearly equivalent. But the
Accordingly, it uses a completely different bytecode than java. However, the Android SDK includes the dex tool to translate java bytecode to dalvik bytecode, which is why you are able to write Android applications in java.
When you install an application on Android, it performs some modifications and optimizations on that application's dex file (the file that contains all the dalvik bytecode for the application). It then caches the resulting odex (optimized dex) file in the /data/dalvik-cache folder, so that it doesn't have to perform the optimization process every time it loads an application.

4 - Empty the cache
5 - Backup and recovery
6- Mount storage
7 - Advance
- Empty the battery status
- Reporting errors
- Keys test

8 - Shutdown
I wish to succeed with nandroid backup and restore method.

Your recovery is not CWM recovery.
You must flash CWM recovery first. With CWM recovery, you can find "wipe delvik cache"
under Advance menu.

Try all basic things, like clearing RAM, Booting your phone etc. If its not solved, try to flash the kernel via recovery. Please ensure that you are s-off for this. Even after flashing the kernel that issue persists, please check your radio (baseband) is latest. Else update the radio. I guess, flashing kernel will solve the issue.
Please let me know whether you are s-off and rooted.
Tips: its my personal advice to be s-off (your warranty voids)
Edit:
If you are HTC.dev unlocked and s-on then follow below steps to flash the kernel.

From where do I have to find "boot.img" ?
I have only back up folder (ROM) from my friend's phone. And I just restored it (including boot.img) with CWM nandroid backup.
Is that the same with your instruction from step 1 to 5 ?
I can selectively restore "boot.img" with CWM nandroid recovery. Is that the same ?
In addition, the version of Kernel I downloaded is the same with my phone currently. I downloaded it from http://htcdev.com/devcenter/downloads
I got primodd-ics-crc-3.0.16-ead8920.zip file. When I extract it, I just found "bcm4329" folder under "primodd-ics-crc-3.0.16-ead8920/drivers/net/wireless" path. I can't find "bcm4329.ko"
Do you mean the driver in my system is not compatible with my phone after restore ?

Boot.IMG is consists of kernel and ramdisk. They both necessary to start up the device, initializing the hardware, phone etc.
Since you are s-on, while placing the boot.img from nandroid, its not well placed. S-0N means, security on that doesn't allows to flash boot.img from nandroid.
I guess, every time you flash the via recovery boot.img is not placed in correct partition.
So, you have alternative method which allows to place the boot.img in correct path.That's why asked to do it via fastboot mode. Hope you understand.
In addition, the version of Kernel I downloaded is the same with my phone currently. I downloaded it from http://htcdev.com/devcenter/downloads
I got primodd-ics-crc-3.0.16-ead8920.zip file. When I extract it, I just found "bcm4329" folder under "primodd-ics-crc-3.0.16-ead8920/drivers/net/wireless" path. I can't find "bcm4329.ko"

Since you have problem only with WiFi and Bluetooth. You can skip fastboot method. bcm4329.ko is same as what you found in the kernel that you downloaded from HTC dev. (Just right click and check the file extension from your pc)
Your friends WiFi and Bluetooth are working fine. bcm4329.ko is responsible for WiFi and Bluetooth. Since you used recovery to restore nandroid, the bcm4329.ko is not placed in the system/lib/modules path. So manually you are placing it
To make it easier do the following
1. From your friends mobile, goto system/lib/modules copy bcm4329.ko file into your pc (use root file explorer)
2. Place that file in your sd card.
3. Then use root explorer and follow the steps mentioned in previous post.( 4 steps under root explorer)
Please let me know if this works.
PS: take nandroid before performing. No warranty for any tips provided. Please do search on google regarding kernel, android partition, bcm4329.ko etc.
Since I don't have pc, I can't help you more with respective links to other sites. Yes, It took much time to compose in my android touch screen.

What does "shine" mean ?
My friend can't find "bcm4329.ko" such a file under /system/lib/modules
So, I'm trying to take matching the files under /system/lib/modules to know the missing files.
Any idea ?

---

My friend told me he has same files as mine in /system/lib/modules
These are the file list
bluetooth.ko
bnep.ko
btwilink.ko
cfg80211.ko
compat.ko
fm_drv.ko
hidp.ko
kineto_gan.ko
mac80211.ko
rfcomm.ko
wl12xx.ko
wl12xx_sdio.ko
He has only those files (not include "bcm4329.ko")
What should I do now ?
