[Q] How to create a Backup of a stock A500 ?

Hi fellow Android lovers
I'm still not sure how to make a proper backup of my completely stock A500 (HC 3.0.1).
My plan is:
1. Root with Gingerbreak
2. Install Acer Recovery Installer App
3. Backup my Recovery with the app
4. Install CWM with the app
5. Make a Backup with CWM
Is this a good/correct way to make a backup ?
What would be the best way ?
Thanks a lot for any useful input

Yes. This is EXACTLY what you should do but with a step 6 added.
Make a copy of your shiney new backups to seperate storage, such as your PC.

Cool ...
Thanks for answering.
Of cause I will safely store that backup on my PC.

A little bit more detail so you don't miss your original recovery.img:
Those interested in getting back their OTA, properly backing up their original ROMS or restoring them, please follow the tutorials in this thread:

Backup Help
I have rooted the device and installed the Acer Recovery app. Where's the backup function ? I can do the restore but how do I backup the device and cw install?
thanks,

you have to reboot into clockwork mod . Recovery .. then in there you can choose backup/recovery

Another thing to try and remember, if/when Acer Recovery updates with a new version of CWM - when you are putting this version on your device and updating recover, don't backup - it will overwrite your "stock" recovery backup with the previous CWM backup (which is likely not really needed with the new version of CWM) - leaving your only way back the final Acer Recovery option of "use stock <whatever version is included with that version of Acer recovery but may not match your recovery version>"
Learned that the hard way

I can, however, confirm that the stock recovery they have still works in all versions of 3.1. Just ran into that with the 4.010.13 update.

Yes, but then you won't have the stock recovery. It also won't be 'stock' because it has probably been rooted and apps removed etc.

It's unrooted if you restore a backup before you rooted your device.

Here's the thing. I want to go back to the stock ROM but I didn't do a nandroid backup. Stupid of me, I know. Anyway, I got from a friend the stock recovery.img(3.0.2.8) and also the stock ROM (U8800V100R001C00B135SP02(WIND-HELLAS)). It is a greek ROM. I applied the recovery.img and now I'm downgraded to 3.0.2.8 from 4.0.0.5. Then, I booted in clockworkmod and tried to apply the stock ROM's .zip . However, I get "Installation aborted" message all the time. I cannot understand where I'm wrong. Maybe someone that did return to stock ROM can help me out here.
edit: Sanpsa, you said that someone should follow the instructions of the extracted files. You mean "UPDATE.APP" and "UPDATE_CUST.APP" files? In my stock ROM with these files you can upgrade the ROM. Is it necessary to upgrade the ROM and then apply the .zip? I don't get it...

If you want the stock Rom back, follow these exact steps:
1 - Go into the Bootloader (pink screen), put the recovery 4.0.0.5 back.
2 - Take out the battery to exit Bootloader (pink screen)
3 - Press Vol+ and Power until you boot into Recovery.
4 - In Recovery go to Mounts and Storage, connect the USB cable and select the last option Mount External Storage (SD Card)
5 - Use the computer to explore the SD card now, Create a folder called "dload" and put both files "update.app" and "update_cust.app" inside the folder.
6 - Disconnect the cable and select the option Power off.
7 - Once the phone is switched off, press VOL+, VOL- and POWER together for 5 seconds.
8 - This should start the automatic installation and you will have your stock Rom back in 5 minutes.
Cheers

These files are not present in the (U8800V100R001C00B135SP02(WIND-HELLAS)) ROM. Only in "overseas". So, I cannot proceed.

Strange, as all stock Roms come as zip archive with these 2 files inside. Are you sure that's a stock Rom?
Did you actually unzip the U8800V100R001C00B135SP02(WIND-HELLAS).zip ?

To give you an idea...
I did these exact steps
1. Installed recovery 4.0.0.5
2. Copy/paste the images ".android_secure", "cache", "cust", "data", "system" and "nandroid.md5" from (U8800V100R001C00B135SP02(WIND-HELLAS)) ROM to mnt\sdcard\
3. Booted in recovery
4. "Backup and restore"-->"restore"
So, into "restore" there is only one backup file from a previous ROM, which btw I don't know how to get rid of it because I don't need it anymore. I can't find any "delete" selection or something.
edit: Yes, I did unzip it. This stock ROM was uploaded by a fellow Greek to provide assistance in such situations. Nobody else complained about his upload for not working.
edit2: I found how to delete backups!

SOLVED!!!
I just pasted the ".android_secure", "cache", "cust", "data", "system" and "nandroid.md5" files into /sdcard/clockworkmod/backup/ and did a restore one by one. AT LAST!!!
Warranty is on...again!

FYI, what you have is not the stock rom, rather a nandroid backup of the (presumably) stock rom..
thats why the steps to restore are totally different in these 2 cases..
anyway glad that u got it sorted out..

No what he means is that you didn't install a new Rom, you just did a restore from a backup...Which is a totally different process altogether and that's why my instructions were not what you needed.

OK. Got it now!

If u restore a backup from recovery to stock rom, then u still have the custom recovery. I you worry about warranties, then you should also go back to stock recovery. Easiest way to do this is to flash any official rom, these restore the stock recovery also.
Like said, these .zips with the two .app files cant be flashed from any recovery.

i think if i do this, i rewrite my rom and i can not boot after this.
are u sure, if this correct operation?

1 - do a cwr full backup (cwr - backup and restore - backup)
2 - flash the new rom as mentioned above, 9 times in 10 it will work fine, no data loss.
if it doesn't boot after the update
3 - in cwr do a 'wipe data factory reset'
4 - flash new rom - let it boot all the way to the android welcome screen, then reboot into cwr
5 - in cwr - backup and restore - advanced restore - restore the sd-ext and data partitions.

its not a new rom. Its camera and browser update. Just 3mb.

Then follow the same steps but instead of wiping everything just flash the update file . Like in CWR choose install zip from sd card . then choose the zip which you just downloaded and flash it .
its actually really simple .
1. Boot into recovery
2. Choose "Install zip from sd card"
3. then "Choose zip from sdcard"
4. Choose the zip file which you just downloaded . the one that has the camera and browser update in it .

oh right, i see now, that option 'flash update.zip from sd' in cwm, , you don't need that one, a normal install zip from sd will do fine, without wiping anything.

Yes it will overwrite your original wmobile rom as booting winsows mobile 6.5 from magldr is not supported yet. You can boot only to windows phone 7 or android. It will not brick your phone it is just bootloader on the top of original bootloader for hd2.

I am also wish to perform an update like the thread starter but I have read from the developer's thread mentioning that I need to reflash the file flash.cfg with a new partition before applying a new update. Would it clean my previous setting of the ROM if I flash a new flash.cfg? Or I still have to go through flashing the entire ROM again? I had previously flash 2 updates on my ROM and noticed a drop in performance speed. I had to do a task29 then reflash back the ROM to get the initial performance speed. Would appreciate anyone's help.

when you flash flash.cfg, you are re riting all teh partitions, so they will all be empty, so you need to do a full backup, flash the new rom, let it boot all teh way first boot, turn off, into cwm, backups and restore - advanced restore - restore sd-ext and then restore data.

[Q] Which custom recovery are you using?

Which Custom Recovery are you using? and why?

I just realized that CWM has a problem on Nexus 7. Can't delete old backups!! You can't delete files in the CWM backup folder thru file explorer, terminal with SU or ADB. For that, and so many other performance reasons, I dropped CWM faster than drunk girl in stilettos. TWRP is what I use on my Galaxy S2 and I just love it. You can queue up several zips for install in order, like: 1) TDJ cache wipe, 2) install ROM, 3) install Gapps, 4) TDJ cache wipe again. then, come back 2 minutes later, and you're ready to reboot. ALso, TWRP has a file manager in recovery, so you can actually delete those annoying backup folders that CWM won't even let you delete. TWRP FTW.

I also notice that TWRP has the nice backup options for "System/Boot/Data" backup only. So I can clean backup my rom without all those apps(which is HUGE)
guess I'll need to put back TWRP in my Nexus 7 again.

TWRP. I tried the latest CWM but even the touch version is not that good for me. Also the De duplication backup of CWM is just not quite right in my opinion. In my experience, leaving thousand files in the sd card is causing performance problems compared to just few large files.

If I flash Clockworkmod Recovery in Rom Manager and then Reboot into Recovery from Rom Manager, I go right to cwm recovery. I have tested making and deleting nandroid backups there and it works just fine. My backups consist of a folder containing 5 files including an md5 checksum so I don't know what people are talking about with 'thousands of files'. I think the people criticizing CWM don't know how to use it. I just make sure I flash Clockworkmod Recovery in Rom Manager before I Reboot into Recovery. Works every time. I don't use the Touch version, just plain old Rom Manager v5.0.2.1 and CWM 6.0.1.0.

I had installed CWM first, but now I changed to TWRP and I like it much more. With an USB-stick connected you have the possibility to backup / restore ROMs from there directly, which makes much more sense than backing up to internal memory. Also the other options provided for install / backup / restore are well done. Really nice work!

Big icon easy to use.

CWM, in all honesty, I unlocked and rooted and have never gone back into recovery. Because this is the first device I've ever owned where I didn't feel the need to flash a ROM yet! ( key word,YET) I use my Galaxy S 2 for my flashing addiction.

[Q] Installing custom ROM's

I've seen instructions for installing custom ROM's where you bring up the ROM file inside Odin (PDA area),
then you place the cell in Download mode, then you hit the [Start] button.
Instead of doing this, why can't you place the ROM files onto the SD card, then use Recovery mode to install them from there?
Thanks!

I only used Odin to root my device. After setting up a custom recovery, I've downloaded all my ROMs to the SD card and flashed them from there. Since you're (hopefully making and) putting your nandroid backup on the SD card, it makes it very easy to recover from an accident.
The method I used was from a Youtube video where the guy used Odin to root, and then GooManager to install TWRP. I've got a custom ROM on my phone and haven't looked back.
Good luck and have fun,
-Jeff

you need a custom recovery, I prefer TWRP, as stated above you can get it through goomanager which is available from the play store. after installing the recovery you can download any rom you want to your pc, transfer it to your phone (either phone storage or external SD) after that go into recovery mode on the phone (hold volume UP home button and power button down at the same time, when you see the Samsung logo, let off all buttons) at this point you can find the rom you transferred, and flash, before flashing anything you will want to do a nandroid backup, then do a full wipe before flashing the rom. after the rom is installed you can go into recovery through the power menu. good luck!

So a couple of questions then:
1: You cannot install a ROM using stock recovery?
2: What's included in an nandroid backup?
I'm assuming it includes the modem/radio files, yes?

1. no, you will need either TWRP ot CWM
2. backs up all your data, etc, so yes everything gets backed up

You use Odin to flash .tar files, which reverts your phone back to stock, unrooted factory condition.
Once you've rooted the phone, you use a custom recovery to install unsigned .zip files, which will generally be custom roms and/or mods.
Stock recovery will only install .zip files that are signed by the manufacturer, such as OTA updates and....not much else. If your phone is rooted, you have absolutely no use for stock recovery.
A Nandroid backup will usually include the boot image, system files, and user apps & data. I use TWRP, which also gives you the option to back up your recovery and EFS partition (telephony data). In most cases, you only need to make a backup of boot, system, and data.
Hope this helps.
