THIS IS FROM EAZYTERRYS
The real answer is if you have ICS, to install a custom recover or custom kernel you must have an unlocked bootloader.
The following resources are related to the new bootloader, a quick read of the OPs of the first two are highly recommended, even if you install with the third link. (This is to have a highlevel idea of what you are changing on your device, as it will help you find what you need to look closer at in future if something goes wrong, or possibly prevent a problem in the first case) bootloader thread civato's guide Afterota tool (windows users bootloader install tool)
If you already have the unlocked bootloader installed, but can't boot into recovery:
This is likely because you have a stock ICS rom overwritting recovery with the stock recovery in every boot; either use fastboot or (if you have root) a program such as acer recovery installer to force the install of a recovery and immediately reboot into it. (Most bootloader installers will also install a recovery that you can immediately boot into)
Once in recovery you can backup/restore/or install a rom modified to prevent the overwrite of recovery. (More advanced users can stop this from adb by removing some files)
Personally I use a lightly modified version of the stock rom you are using now: http://forum.xda-developers.com/show....php?t=1661492
it ought to be safe to do a no wipe update to that and receive a more expected environment with a custom recovery, optional custom OC kernel, and busybox support.
However if you explore the dev section, many other (both more and less modified) versions of ICS roms exist. Themed and otherwise. So feel free to explore.

Flash custom recovery on an already rooted Aria with clockworks recovery?

is it possible to switch to another custom recovery after I already got clockworks?
I tried unrevoked but its stuck in the reboot (I believe its trying to root my aria again)
not sure what youre trying to do.... i believe Clockwork is the only Recovery for rooted phones. if you want to flash a custom ROM, well that is something else altogether. please be specific as to what you want to flash to the phone. include a link to the flash too
I was trying to flash psfreedom recovery rom from here
http://psfreedom.com/wiki/HTC_Aria
I believe the method on that website was for unrooted arias without clockworks

To flash a different custom recovery on your Aria, you need to rename the zip file LIBEIMG.ZIP on the SD card and boot in HBOOT (Power on the phone by holding down VOL DOWN and the Power Button). When it boots to the HBOOT screen you should see text stating that it found LIBEIMG.ZIP and is installing it.
awesome. now before I go ahead, is there any clockworkx recovery image I can revert back to?

I'm curious, what recovery are you talking about?
thanks for including the link. the instructions are clear.... Root IS required, Clockwork recovery is recommended, the Freedom Aria flash appears to be a custom ROM.
once the phone is Rooted, boot into Recovery, make a Nandroid backup, and flash downloaded zip file from SD card.
if you need help Rooting, there is all sorts of good methods available on this site. I use the Unrevoked method myself, but it works best on Linux or Mac OS

hmm I think you are looking at the old method which is a custom rom
The new one is a custom recovery which brings me to the question as I dont think you can flash a custom recovery in the clockwork custom recovery.
its possible im looking at the wrong thing, but far as i can tell it states "Recovery Custom ROM" which is totally different from Custom Recovery ROM
From link posted above:
"Update can be installed in recovery mode in Psfreedom settings menu via Update (local) or Update (net) if you have configured your wifi connection. Put the file on your SDCARD and install it.

I have similar questions. I was trying to update my version of clockwork also using unrevoked again, but couldn't get it to work. I guess my questions are:
1. Is there any benefit in updating to a newer version of clockwork? My current version is 2.0.x.x and I believe the latest one is 2.5.0.4.
2. Will this same method work to do so? Can I rename the latest clockwork .zip file like this and get it updated?
I thought using the flash clockwork option in ROM Manager would do it, but it doesn't. If I reboot from ROM Manager it goes to the newer version, but if I reboot otherwise it goes to my original. The couple times I've used it, there appears to be maybe some different features/options in the newer one and I feel like I might be missing out on something!
What's the difference with this recovery?

These are probably two different things. once you got the recovery rom flashed you can upgrade it in recovery mode (hence its different from original clockwork recovery)
Ok bro, I didn't see much info about it so I'm gonna take your word for it.
@brswattt, far as I can tell this is " basically" used for jailbreaking the ps3.
@armyengineer;
you can use unrEVOked to flash the new recovery. if youre a Windows user, download the unrEVOked tool and run the .exe as Administrator. also make sure there are no conflicting s/w on the PC such as HTC Sync and you have all the drivers installed(HBoot, ADB drivers, etc.)

This still isn't working for me. Everything appears to go well at the start, then I get:
Waiting for root...(safe to restart if this doesn't work)
At which point the only way I can restart is to pull my battery. After doing so, it reboots and I get:
This was a triumph
It is not, however, any such thing. After another minute I get this:
Internal error: couldn't find misc.
So I've still got my original version of clockwork, 2.0.1.3, despite the fact that ROM Manager is telling me I have 2.5.0.1. I'm obviously missing something here.
BTW, if it matters I'm running CM 6.1.0

Although there is a ClockworkMod 2.5.0.4 version, I don't think it is for the Aria. According to ClockworkMod ROM Manager, 2.5.0.1 is the most current one for the Aria so I am believing what ROM Manager is telling me since it is written by the same the vendor.
I have tried CM 6.1.0
original HTC Aria 2.1 International Rom
and FR001 RC1
all no go. I think it has something to do with the phone already been rooted and has clockworks installed which makes unrevoked unhappy

OK, let's start from the beginning. You asked about installing an alternate recovery (PSFreedom recovery), but apparently it has its own installation procedure that needs to be run on an unrooted Aria.
What you need is to find just the PSFreedom recovery and copy it to your SD called in a file called LIBEIMG.ZIP and that is how you need to install it on a root phone that has ClockworkMod. Perhaps you need to go back to the PSFreedom thread and ask if a LIBEIMG.ZIP can be produced that can be flashed from HBOOT to replace ClockworkMod.
Looks like everything you need is located in the PSFreedom wiki:
http://psfreedom.com/wiki/HTC_Aria
I got a recovery.bin which is suppose to be used with unrevoked.
are you talking about the same one if I just compress it into a zip file?

[GUIDE] Install ClockworkMod Recovery image after updated to 2.3.4 (GRJ22).

Not applicable
Delete this thread
Hello, thanks for the post.
I got a brand new Nexus S, I got a update direct from Google so I just flash it to GRJ22 :-(. I follow your guide (I have to do the step 1/2 in the other post you refer). Now I got clockwork done. But everytime I restart my phone, I always boot into clockwork. I try to 'mount sdcard' and reboot, but still boot into clockwork. How can I boot into the stock ROM?
many thanks!!
Too complicated.
Just:
1. turn on phone by holding volume up + power to go to bootloader
2. fastboot oem unlock (confirm it on the phone)
3. fastboot flash recovery recoveryfilename.img
4. Select recovery on the phone.
5. You're in ClockworkMod. Go flash a new ROM.
Let me answer myself.
I don't think the latest rom 2.3.4 is compatible with the clockwork you supplied. So I have to flash my phone back to GRH78. I downloaded the stock ROM from the internet. and then push all the images file into /sdcard/clockworkmod/backup/2010.xxx.
Next, I restore the image in clockwork menu.
after restore, reboot the phone, now I am back in business.
When the phone is boot, i lost the root again, so i went to modaco.com and get Paul's package. run it, restart, I got the root.
Finally, go to market place and get ROM Manager, install the clockwordmod. and I have a 'proper' phone.
although I don't have the least rom, at least i got a working phone that is rooted.

I have the same problem. How did you handle it?
Wow, why risk messing up your phone with flashing a boot.img when you can just rename /etc/install-recovery.sh to something like /etc/install-recovery.bak?
Here's one way to rename (courtesy of Matridom). Another is to use Root Explorer.
Matridom said:
The new update applies the install-recovery.sh script into our phones (not there previously.
Boot into the bootloader
flash CWM
select recovery from the bootloader (DO NOT reboot the phone)
apply the su binary
boot into the OS and test root
make sure busybox is properly installed
run ADB shell
then:
Code:
su
mount -o remount,rw /dev/block/mtdblock3 /system
mv /system/etc/install-recovery.sh /system/etc/install-recovery.bak
Boot back into the bootloader and re-flash CWM, should stay permanent now.l had applied the SU binary at the same time as the OTA update, then renamed the installer script and flashed back CWM.

This is a totally unorthodox way to make the custom recovery permanent. If your phone is messed up, good luck fixing it.
There is a much easier and safer way like I mentioned.
PS: flashing recovery for 2.3.4 is the exact same as for 2.3.3!

I cant use command prompt, as it says "Image cant be loaded".
So I had to use this method.

so I decided to share it
Hope you understand.

Wow people like to make things complicated. Why install an entire rom to get ride of a script?
if you can flash cwm, you should have some basic understanding of fastboot, adb and the search options in the forums. the answers are all there already.
Sent from my Nexus S
No disrespect, I agree flashing recoverys should only be done after you understand how to use the tools to do it. there is no reason someone who is going to mod systems on their nexus shouldn't be able to use fastboot and adb properly. all the right drivers are in the sdk.

This is what I did.
I rooted my NS, which had 2.3.3
Used phone with stock 2.3.3 until I figured out which ROM I want to flash.
Before I flashed any ROM, did a Nandroid Backup through CWM.
Used the ROM for a few days, but when I saw that official update is ready for download for i9020A, did do a restore from the Nandroid backup I created.
Updated from 2.3.3 to 2.3.4, phone works fantastic, video chat also works great.
After update when I tried using any of the apps required SU permission, they didn't work. I tried installing a couple of .apk files, couldn't either install it or after installation it didn't work.
Thought let me try wiping my phone clean and start all over again, may be I will use a custom ROM again, downloaded ROM, went to ROM Manager to reboot into recovery, nothing happens.
Tried booting into Recovery option manually by pressing Volume Up and Power button, nothing happens but the Bot with an Arrow appears on screen.
So, I thought I will follow this procedure to reflash CWM to my phone and get it going. I was able to use the command FastBoot once, and suceeded pushing .img file to my phone but now whenever I try using the commands from my computer, this error message appears : "This application has failed to start becasue AdbWinApi.dll was not found. Re-installing the application may fix this problem."
Why this error message if I have the sdk on my computer already through which I was once able to push .img file without any troubles?
Can anyone tell me what would be a possible solution?
Also, how can I fix this problem and get ClockWorkMod Recovery installed on my NS again?
How can I get stock recovery image on my phone if I want start all over again from scratch?
Thx a million.
Edit ::: I found the answer as to how to how to install CWM again. Thx anyways.
Other question still remains a puzzle... why am I not able to install certain programs or if did manage to install, can't run them?
I ran your method and I think I'm stuck at some step...
My phone now default boots into CWM 3.0.2.4
Recovery boots to a newer recovery I flashed.
How do I get my phone to default boot into the OS again?
Edit: nevermind, just downloaded the full 2.3.4 rom, extracted and flashed the original boot.img.

After installing the sdk and a platform, I have adb, but where is fastboot?
I was getting the same error as "Image cant be loaded". after hours of struggling I found that It's only because I was not in the same directory as the img file. silly eh?
hi,did you repaiar your phone,i have try everything but it just keep going in clockwork mode,if i than pres reboot now in clockworkmode it stays on google padlock
i realy need phone if you can help or someone else,than ....
just tried this method of window7 (thanks for the work) with cwm 3.0.2.4, but got the same result like the others in this thread: cant boot the android 2.3.4, the system is always booting into the cwm, no way out.
I don't think this tool works as it should.
:-(
EDIT:
I didn't realize that window7's tool would install the cwm into the boot-partition instead of the recovery-partition.
To get my boot partition back I downloaded the 2.3.4 firmware image from http://forum.xda-developers.com/showthread.php?t=1056062 and extracted the boot.img from the zip.
with "fastboot flash boot boot.img" I restored my orginal boot partition an can boot into android again.

Unable to boot into recovery using "Acer Recovery" from market/playstore

Hello. After updating my A500 to the official ICS rom, I easily rooted my tablet succesfully by downloading a program found on this website:
http://forum.tegraowners.com/viewtopic.php?f=30&t=350
Then, I downloaded an app from the market/play store called "Acer Recovery" wich lets you flash CWM recovery (which is built in into the app). The app said it flashed the recovery succesfully. Now, when I press the "boot into recovery" button I get stuck in the Acer logo and on the top left corner it sais in red: Recovery Failed
I would like to flash custom roms. What am I doing wrong?

Firmware Specs are same as yours
I wonder if there is a simple way out
Anyone can help ?

Ok, both of you need to go to this thread and read over the info.
The reason why your recovery "might have failed" is probably because you didn't delete a certain file from your rom before you flashed your CWM. That is... "recovery.from.boot.p" in the system folder.
If you don't, every time you reboot your will lose your CWM.
Anyhow, read this thread. Everything you need is there.
http://forum.xda-developers.com/showthread.php?t=1622425
And if you;re going to install some ICS Customs in the future, I advise you install a patched unlocked bootloader.
EDIT: One more important thing. Before you folks go off flashing and everything, PLEASE... Get your UID number now, and write it down in a safe place (like the box your tablet came in . If you tab gets borked up, it's the only thing that'll save it.

I would advise making sure you have at least Version 3 or higher of the unlocked bootloader. Version 4 is better as you can change the boot image. Also, with version 4 (and higher) you can flash any future bootloaders through CWM.
Also, make a system (nand) recovery backup before you go flashing roms. This way you have something to go back to if the flash doesn't go right.
part of the original problem you had was the recovery you tried to flash was an earlier version which doesnt match ICS , You can get the beta copy of Acer Recovery ,but you'll have to search for it , it also has updated ICS recovery listed

It's serious: I need help... flashing stock A501 rom

Hi,
atm, I have an A501 with CWM-based Recovery v5.5.0.x(thor2002ro rev1.7) and Android 3.2 (EMEA CUS7 - Germany).
My Tab tells me that there is an update, which I downloaded and tried to install. However, after a few seconds an Android with a red exclamation mark appears and the installation of the updates aborts.
So, I want to remove CWM Recovery and root and return to a stock rom. However, that seems impossible. I downloaded the Acer Recovery Installer App but this one offers me a USA A500 stock rom - but I need an A501 rom because of 3g.
When I try to install this one (http://forum.xda-developers.com/showthread.php?t=1234039) I decrypted before, CWM tells me
"Installating update...
Installation aborted"
So, this does not work either.
I am really desperate because I have to revert to a stock rom...
Can someone please, please, please help me out?

The update has overwritten yr custom recovery with the Acer stock recovery. It also checks yr system files if it ain't completely stock it will abort. being rooted can also affect the update.

Yes, I did install cwm again from acer recovery installer, but that did not change anything.
Unfortunately none of the roms offered on xda work, they all abort in cwm and I don't know why.
I would prefer to go back to a stock rom with stock recovery because I want to give the tab to someone else.

Yes, I did install cwm again from acer recovery installer, but that did not change anything.
Unfortunately none of the roms offered on xda work, they all abort in cwm and I don't know why.
I would prefer to go back to a stock rom with stock recovery because I want to give the tab to someone else.

Yeah, you may have difficulties flashing full packages via CWM. Especially if you didn't decrypt the rom first.
I've got a few 501 roms you can try. All HC 3.2.
One of them, is an ATT full package update which will probably work for you. Just pull the update.zip out of it. Put it on your Ext SD card, and boot holding PWR and Vol+. This will force it to install update.zip from the SD card.
Any rom you use, you have to decrypt it first. Some try renaming the rom to update.zip, and some have success using this method.
Like I say, it's an AT&T rom, but is probably really a ComGen 1. So it should have decent language support.
If you're interested, I can throw them up on a server tomorrow.
But I tell you this first, before you go messing around with these things. GET YOUR UID Number first, and write it down. You can get instructions on UID in the Development Forum, 1st page usually. It's easy.

No probs!!
U must use a "update.zip" , decrypted first as Moscow said, and booting into recovery via button combo may help too,
also remember to remove the zip file off the ext. sdcard when you are done!!
....good luck

[Q] Can't Enter Recovery Mode to do anything

Hi,
I need a little help as I am a complete noob and have just crash landed into the world of Rooted Roms.
I recently rooted my stock 4.0.3 ICS rom for my Iconia tab A500, using blackthund3r_ICS_Root_6.0. It worked brilliantly as far as I can tell. The Superuser function is there and I even deleted some of the annoying stock games that are on the stock ROM.
As the next step, I installed the Acer Recovery
However, I am interested in trying a leaner custom ROM in order to improve the performance of my tab, so I downloaded the Acer Recovery Installer from the Play store. I chose the Recovery version CWM rev1.7 by thor2002ro (for ICS Bootloader) and clicked on the install Recovery Image.
When I clicked on the Reboot into recovery mode because I wanted to back up my ROM and eventually install a leaner faster ROM, I got the following error message:
Booting recovery kernel image
Recovery verified failed ...
Anyone have any suggestions to help me out?
Thanks in advance for your help and putting up with my Noobish ways!!!!

sounds like your rooted correctly if u cud install the recovery file, but u should use thors cwm 1.7.3 to flash roms because it supports aroma installer which the newer roms use. did u get message from acer RI saying recovery installed?
u can find cwm 1.7.3 by thor here .
just put the zip from that link on ur sd card
if u can get into the recovery you installed.
choose install zip from sd in your cwm menus and select the zip.
let it finish then reboot.
viola! you have updated your recovery and shud be able to make the backup u need.
it is what i used.
if u cant get into recovery yet try turning off your tab
power it on and hold the volume down button.( the volume rocker side closest to the power button)
hold them to u see the white righting in the upper right corner of your acer screen
if u get in, update.
if u still cant get into recovery. try one of those other recoveries
try to install thors cwm 1.7.3 zip from there.
if u like i cud point u to some roms ive tried, since we have the same tab. happy to help.
Hi shadowmikeshadow;41918411
I will give it a go and tell you if it worked. Thanks for your advice. After all I could use all the help I can get. I am totally new and clueless to this whole rooting thing. I've only had my tablet for about 9 months and I got tired of all the lags and thought it was time to root and get rid of all the bloatware.
I really appreciate all the support you profis out there are offering. In general this whole site is GREAT!!!!!
np man im happy to help. well get u goin for sure
also couldnt hurt to double check your root with root checker(free app) could be making ur AcerRI not work correctly
and if u still cant get it to work and u are rooted correct theres still more we can do. its just more complex so try those first..
Do I have to do anything with this Recovery zip file that you suggested. I put it on my SD card and rebooted in Recovery mode and I still get the same error.
Please keep in mind I am complete Noob at this.
Thanks.
So if u can't get any recovery working install that zip via adb.
u can download this so u won't need android sdk.
follow all the instructions on the platformer page.
If everything went OK and adb sees your device
Follow this guide for adb here
but use the recovery from the zip in earlier reply.
Still desperate

Hi Everyone,
As of posting this original thread above I am still stuck in limbo. I have read, read, and read and am more confused then ever.
There are so many suggestions out there and I dont know what to do.
My problem is this: I have no way to enter the recovery mode to do anything (flash a new ROM or Stock)
If someone out there has the time and patience to help me and can talk me through step by step how to fix this problem, it would be highly appreciated.
Thanks for your understanding and support.
