Flashing A Recovery Rom..

I have searched this forum multiple times and i can not find my answer so i am posting this hoping someone with some patience will help me.. when i followed these steps.. "III: Flashing a Custom Recovery
Flashing a custom recovery will make your life easier when flashing ROMs in the future.
1. Download this file: Recovery.zip
2. Extract file contents to your \tools\ directory of your Android SDK.
3. Open up a command prompt and go to your tools directory, and execute these commands:
•adb shell mount -o rw,remount /dev/block/mtdblock3 /system
•adb push recovery.img /sdcard
•adb push flash_image /system/bin
•adb shell chmod 755 /system/bin/flash_image
•adb shell flash_image recovery /sdcard/recovery.img
4. Success! You now have a recovery partition installed on your phone. You can access it by running "adb shell reboot recovery" or by powering off your phone, holding "Volume Up + Power On"
It says that what i have typed is not an executible file.. someone please help.

are you 100% sure that you extracted the file out of the zip and not just put the zip into the folder?

yea im sure

Are you typing out each command? or are you pasting them into your terminal? Also, what OS are you running ADB from, and have you had success with it before? Or is the eris your first android device
Also, you did the previous steps first correct? IE: you're ROOTED

there is an easier way posted by i think Zinfab it was something like.
su
adb shell
reboot bootloader
at this point make sure it says fastboot USB on the screen
then in the same window fastboot flash recovery recovery.img (make sure your recovery.img is in the same directory as all your SDK tools)
this worked for me when the method u posted didn't work

where do i type this stuff in at.. i have my phone plugged in usb debug checked i installed the usb driver update it and i have the recovery thing extraced in my tools folder now what do i use my computers command prompt or my phones command prompt

did u set the enviromental variable? its not that important I'm just curious.
if not in command prompt first command would be
(directory to tools)\adb shell
"su"
"Reboot bootloader"
then once its in bootloader
(directory to tools)\"fastboot flash recovery (directory to recovery.img)"
now the quoted sections should be typed exactly as is, without the quotes, but you have to know your own directory.

when i type it in on my phone it says adb not found

whats that

ok my phone now is in fastboot usb mode what do i do know

as suggested, did you set the variable? type fastboot devices to see if its even working correctly, to start.

how do i get out of fastboot usb

Type in the command fastboot flash recovery recovery.img

ok now it says waiting for device

You didn't search that well.

[HOWTO] Recover from checksum errors

As I've seen a few people around having some checksum erros, I decided to write a small HOWTO.
!!!
The most important information needed to recover from a bricked device is the UID
If your device is not bricked and you read this thread ensure that you have saved your UID!
!!!
​
Because some people do not read big red text, here it is once again:
GET YOUR UID even if your device is not bricked.
If you need help please contact me with PM or ask for help in this thread.
If your device does not boot anymore it may display the following checksum erros:
"LNX checksum error" - when trying to boot into normal mode
"SOS checksum error" - when trying to boot into recovery (VOL- + Power pressed)
<CASE 1> SOS checksum error
Steps:
- Switch off your device by pressing power for ~8sec
- Switch on your device and boot into normal mode
- If LNX checksum error is displayed, stop here and see <CASE 3>
- Download itsmagic (see this thread). Extract "itsmagic" to the tools folder of android sdk.
- Connect your device to your PC (Windows: drivers can be obtained from Acer website)
- If not already done, get your UID using Method 1 of "How to get the UID"
- If not already done, get a dump of mmcblk0_start (see "How to get a dump of mmcblk0_start")
- In the command window type:
Code:
adb push itsmagic /data/local
adb shell
su -
chmod 755 /data/local/itsmagic
/data/local/itsmagic
exit
- If everything went fine you should see some output of itsmagic
- Reboot and check if you can boot again
- Store your UID and mmcblk0_start to some safe place
Possible reasons for this error
- You tried to install a new recovery without calling itsmagic before
- You have not remove /system/etc/install-recovery.sh
- Your recovery partition is corrupt
<CASE 2> LNX checksum error
Steps:
- Switch off your device by pressing power for ~8sec
- Switch on your device and boot into recovery by pressing VOL- + Power
- If SOS checksum error is displayed, stop here and see <CASE 3>
If you have stock recovery:
- If not already done, get your UID using Method 2 of "How to get the UID"
- Apply an official OTA, see this thread
If you have thor's CWR:
- If not already done, get your UID using Method 1 of "How to get the UID".
- Select "reboot system now"
If you have any other recovery (that does not have itsmagic integrated):
- If not already done, get your UID using Method 1 of "How to get the UID". If Method 1 does not work, try Method 2
- DO NOT apply any official update.zip . Otherwise you will end up in <CASE 3>
- send me a PM or ask for help in this thread.
Possible reasons for this error
- You tried to install install a new kernel / stock update.zip without calling itsmagic (will not occur with thor's CWR)
<CASE 3> SOS and LNX checksum error
- If available, upload the "mmcblk0_start" dump to some file hoster (e.g. dropbox)
- Send me a PM with your UID and a link to "mmcblk0_start"
- If you do not have your UID: DO NOT connect your device to your PC:
- Pray that you are able to recover the UID from a PC the Iconia was already connected once.
- Windows: Try Method 2 of "How to get the UID" but DO NOT connect your device to your PC.
- Linux/Mac: Check old syslogs for messages where your device was connected to your PC (normally some "usb " kernel messages)​
Possible reasons for this error
- You tried to install a new kernel athough you already have a SOS checksum error
- You tried to install a new recovery altough you aleady have a LNX checksum error
How to get the UID
Method 1
- If not already done, follow the instruction "Howto install ADB" below
- In the command shell, type:
Code:
adb devices
and press RETURN
This will output something like this:
Code:
List of devices attached
370014740c00594 device
The number is your UID.
- Save this number somewhere it won't get lost
Method 2
- Connect your device to your PC and ensure that drivers are properly installed (Windows: Can be downloaded from Acer website)
Windows:
Download this tool (download link is nearly at the end of the page):
- Open the tool
- Sort after VendorID
- Find all devices with VendorID = 0502 and ProductID = 3325. Check the "Serial number" column for these devices.
Linux:
Call (as root) and see the iSerial field for Iconia.
Code:
lsusb -v
Mac:
- Should be visible in system profiler. Sadly I don't own a mac. So if anyone can help me out with this?
How to get a dump of mmcblk0_start
- If not already done, follow the instruction "Howto install ADB" below
- In the command shell, type:
Code:
adb shell
su -
dd if=/dev/block/mmcblk0 bs=512 count=13312 of=/sdcard/mmcblk0_start
exit
exit
adb pull /sdcard/mmcblk0_start .
- This will create a file "mmcblk0_start" in the tools folder of your android-sdk.
- Copy this file to some safe place
How to install ADB
1. Download android SDK from here. Windows: Download the .zip file instead of the exe file.
2. Extract android SDK somewhere
3. Open a command shell:
- Windows: Press Winkey+R . Some small window appear. Enter "cmd" and click ok. A black command promt window will open.
- Linux/Mac: Open a terminal window
4. "cd" to the "tools" folder of the android sdk by typing the following in the command shell:
- Windows:
Code:
cd "<path to tools folder>"
Sample:
Code:
cd "c:\android\android-sdk-windows\tools"
- Linux/Mac:
Code:
cd /path/to/tools/folder
5. Ensure that your device is connected, that drivers are installed and that USB debugging is enabled (on Iconia: Settings->Applications->Development->USB Debugging)

Im just asking, in case3 u need dump of mmcblk0_start ,but what if dont have it, only UID?

Having a dump in <case 3> makes everything easier. But it is not mandatory. Nevertheless it's generally a good idea to backup mmcblk0_start.
btw: thor's CWR will backup mmcblk0_start since version 1.2 if you do a nandroid backup.

Code:
if: illegal argument combination or already set
What i should do?

when i get a SOS checksum error and a LNX checksum error,can i copy files from pc to a500 device? how?

The procedure for this case is much more complex. If you do something wrong, it is getting even more complicated.
I will not publish details currently, sorry. If you get this error, contact me.
As soon as some tools are finished i will update the OP.

You need to be root
Type
Code:
su -
before.
I will update the guide

Thanks but it's doesn't work yet. I have root access. I tried type "su-" but it is the same message "cannot open for read: Premission denied". I install usb drivers and the others think from guide hmmmm....

Did you type su- or su - (notice the space between su and -)?
Also you'll have to confirm su permissions on the tablet.

I typed "su -" with space between su and -
I have USB debugging turn on
When i type "su -" it say "Premission denied"
I really sorry for problem and thanks you for trying to help me

Is your device rooted? Because it has to be.
And if it's rooted did you notice a superuser app popping up after you run the command.

What a shame, I did not notice a superuser app popping up :/ Now it's ok. Thank You very much. I must learn a lot. Only think was taht I can't pull this file to my computer via "adb pull /sdcard/mmcblk0_start" but i copy it directly from device Now I feel safe.
Thanks a lot guys

Well, actually you should be able to dump directly to adb without copying to device to save some time.
like dd if=/dev/mmcblk0p1 count=X bs=Y
but without specifying of= or using of=-
and don't forget to redirect it to file. like "adb shell "dd if ..." > dump_p1". Not sure it will work fine, but I used it once on another device to dump block device image.

i download the android sdk zip file, but is seems that the "tools" folder doesn't include the adb executable file , how should i do?

[Guide][NOOB-Friendly] How to share your Nandroid Backup and Modem

As we are having a lot of Jelly Bean leaks lately, a lot of users want to share the Nandroid backup to others but sometimes they make mistakes which ends up in md5 mismatches or some of them don't know how to create a share-able zip.
I have tried to create this guide to enable them in doing so. Hope this will help everyone.
Requirement:
CWM Recovery
7zip, Winrar or any file compressing tool
ADB setup in your PC

Once you have applied the OTA and done a factory reset, Follow the process given below:-
If your have ClockworkMod Touch Recovery 6.0.1.2 (Believe me it is easier and better in Touch recovery - Get it from here) follow these:-
In CWM Recovery
Reboot into Recovery => Hold Volume Up + Home + Power buttons together for about 5-7 seconds, release the buttons when you see the recovery menu
Choose -> Backup and Restore
Chooose -> Choose Backup Format (Optional)
Change Backup format to tar (Optional)
Choose -> Create image.zip
This will create an image.zip and an image folder in your Internal Sdcard inside the clockworkmod>backup folder
Copy the image.zip file to your PC, rename it to the software version you are sharing for e.g. GT-I9300-XXXXXXXX. Important do not put spaces in the name.
Upload this zip to whichever Filehosting site you want to share with.
*this image.zip can be flashed in CWM directly without having the need to extract the files inside*
Click to expand...
Click to collapse
If you have ClockworkMod Recovery 5.5 (Get it from here) Follow these:-
In CWM Recovery
Reboot into Recovery => Hold Volume Up + Home + Power buttons together for about 5-7 seconds, release the buttons when you see the recovery menu
Choose -> Backup and Restore
Choose -> Backup (either Internal or External SDcard by default it will backup to ExtSDcar)
Your Backup will now be there inside the clockworkmod>backup folder, Copy this folder to your PC
Zip the Folder and give it a name for e.g. GT-I9300-XXXXXX (Dont use spaces)
Now you can upload this zip to any filehosting service of your choice
Click to expand...
Click to collapse
How to extract the modem:-
For extracting the modem you need to be rooted (If you are not or want to know how go here)
Using ADB (Go here if you want to know how to set up ADB)
Connect your phone to you PC (Please ensure that ADB debugging option is checked in Developer Options)
Type
Code:

Well that escapes me..may be someone knowledgeable can shed some light on it..
Sorry..
Maybe the that provided with the firmware is a patch..I know OTA files are patches but can't say much about full firmwares..

I'm trying to do this using the terminal emulator in Rom toolbox and u keep getting permission denied?
(from what I understood we had two ways of doing this correct? A computer and adb or TE, correct?)

thank u soooo much bro i just successfully un brick my device tomorrow i will make a thread again thanks for ur time and million thanks to u :laugh:

Hi, I've used your CWM script but it doesn't have created the ZIP file with the debrick image.
I've searched it on all memories (also the system folder) but nothing. I've a GTI9301I ITV Firmware UANI1
I've tried also the adb shell and when i type adb pull /sdcard/debrick[phonemodel-memorysize].img it show me no devices (but it's enabled and the phone receive correctly commands)
