Question about flashing and restoring - Xperia Arc Q&A, Help & Troubleshooting

I've been using JJ's hybrid + ArcKnight Kernel, but now I want to test a GB firmware.
I downloaded this from XDA: "LT18i_4.0.2.A.0.62_Generic World UK.ftf", which I think is the latest stock GB.
I've made a nandroid backup via ClockWorkMod, however, looking into backup folder I see there are only 4 files inside, which are
data.yaffs2.img (370 MB);
system.yaffs2.img (190 MB);
cache.yaffs2.img (37 KB);
nandroid.md5 (some bytes);
My questions:
1. When I flash the above .ftf file with Flashtool which folders/partitions will be overwritten?
2. How about the other folders such as /etc, /sys, /dev and so on?
3. After flashing the above .ftf file, will I be able to restore my current ROM only by restoring those 4 files with ClockWorkMod?
Thanks guys!

Answers to your questions:
1. When you flash a ftf file, everything on your phone will be flashed unless you have chosen not to flash certain contents of the ftf like the simlock.ta since it will lock your phone to the UK network. The options are under Flashtool which you can select prior to the flashing operation.
2. As I said earlier, everything on your phone will be flashed. These files will be overwritten. Only the memory card is not affected.
3. Yes, you can, but you have to flash a CWM kernel after flashing the ftf file as the ftf file also flashes a new kernel.
Hope this helps

Deleted System/Apps folder by accident

I was deleting some junk files from the Apps folder and when i finish i deleted the whole folder by accident, My phone keeps rebooting I have an Arc S L18a.
Please Help. Thanks
What rom are you on?
If you are on stock, you could extract the system/app folder from the ftf file, make a flashable zip from it and flash the folder back via CWM.
If you are on a custom rom, flash the rom again without clearing data.
Don't forget to make a nandroid in case anything goes wrong

I'm dont think im using custom rom, I just rooted my phone with the help of this thread (http://forum.xda-developers.com/showthread.php?t=1683957).
How do I do that?
Download the ftf file for your phone from this thread
http://forum.xda-developers.com/showthread.php?t=1330314
You can extract the ftf file with winrar or 7zip.
Then use the Xperia ROM Manager to convert sin to img and then unpack system.img.
http://forum.xda-developers.com/showthread.php?t=952732
When you've unpacked the system.img you can drag the contents of the app folder into the update.zip, copy the update.zip to your sd card and enter CWM to flash it.
http://www.mediafire.com/?1268g66o25ehqkm
Use this app to install CWM to flash the zip.
https://play.google.com/store/apps/details?id=com.pvy.CWMinstaler&hl=nl
When your device starts booting, keep hitting the volume down button until you get into cwm.
Then select "apply update from sd card" with the volume keys and press it with the home key.

[Q] Problem with nand bakcup

Hello
My problem is that I downloaded the nand stock rom from the thread and extracted it and tried to put it in the clockworkmod\backups folder and I think it was ok (not sure) but by mistake I deleted all of backups (the stock and the one i created) and I tried to copy it again and create another one but I noticed that there never 2 backups.
The one that I created I can see only from the restore option in recovery and not in the folder ( I used to see it in the folder ..) and the stock one I can see in the folders but not in the restore option.
Should it be like this ? Am I doing something wrong ?
How can I restore that stock backup if I cant see it ?
I'm on ordroid 9 with TWRP recovery.
And the stock one gets in ZIP but i extracted it and copied as folder.
Thanks in advance , I'm afraid to flash new version.
That's because you didn't put it into clockworkmod>backup folder in the sd card and btw you don't extract anything .....every nandroid backup must have 5 zip files in it (don't extract it) and should be named as the date and time it was created
The folder should be like this
Clockworkmod\backup\date & time folder\backup files

I know :\
I extracted the stock backup folder from the zip . not the content in backup.
Forgot the part about renaming, that actually might be the case.
Thanks both of you, I'll try it.

[Q] Extend internal memory

Hello! Could you provide step-by-step guide on how to extend internal memory in i8160 or replace USB+internal with internal partitioning only? Thanks!
That's how I did it.
I flashed aem's stock prerooted rom, using Odin.
With terminal, using dd command - I flashed custom recovery HD 1.2 with twrp.
Then downloaded modified vold.stab file ( in the development threat some dude linked his file, sorry, I forgot his nick ), and flashed .zip in recovery.
That's it.
Check out my Dropbox Folder for the kernel and the modified vold.fstab:

Flash with recovery.

how to restore a nandroid back up rar file

hello. i need to get back to stock im on cid htc 001
h,boot 1.39.0000
radio-5.1204.162A.29
3.20.401.1
what i think iv found out is that there is no ruu out for this, iv found a nandroid bk up but it is a rar file. this is what im stuck on how to restore with it
Open the rar with winrar/winzip/7zip and extract all the files to your pc... and now transfer all the files to your phone in this directory /clockworkmod/backup/02-06-2013/ and put the boot.img file in the fastboot folder.
Go to fastboot mode and then flash the boot.img and then erase cache... Go to recovery and then wipe everything! and finally restore backup and then reboot!
PS: I'm assuming you have a backup made with CWM recovery!
CWM recovery made 2 rar file

can any1 help? has any one experienced this type of backup and restored using these type of files?

[Q] embarased for asking this.

In TWRP, when you flash a rom you are pointing it to a .zip file, or bootloader or modem or whatever. Great, but when I create a backup of my rom in TWRP it doesnt make a flashable .zip it just makes 4 .win files. If I then go into TWRP and select restore it asks for the location of the .zip and if I go to that location obviously there is none to be found. Do I just use like winrar or 7zip and make it a .zip or what? I dont understand this and I better because If I ever need it Im screwed.
TWRP backups are not zip files. You point it to where TWRP created the backup folder.
