Can't flash CWM on ICS

I just bought a used Xoom Wifi. It was running Stock Android 3.2.1. Got the update notification to ICS. Updated to ICS and then tried to install CWM doing these steps:
1. Unlocked Bootloader
2. After successfully unlocked the bootloader tried installing the CWM 3.2.0 R4c
3. When I try to enter into recovery I get a Android with a red exclamation symbol and the I enter into Android Recovery.
I have tried changing the .img file name and flashed many times but nothing seems to work.
Any helo would be appreciated
Thanks

going from Thor to Stock

Hello,
I have an A500 with 8GB, bought in USA nov 2011.
it is currently running Thor/TegraOwners ICS ROM v164 (with CWM recovery)
my back-facing camera stopped working and I would like to go back to stock to send the tablet in for repairs.
I got the full stock firmware from here: http://forum.xda-developers.com/showthread.php?t=1113878 (Acer_A500_0.000.00_4.010.10_COM_GEN2_1310535068614_9b84abb1)
unfortunately, I'm not having much luck flashing this :| ... I decrypted the zip and extract the update.zip and put it on the sdcard.
-tried applying update.zip through CWM ... no luck (it extracts but nothing happens)
-tried installing stock recovery using 'acer recovery installer' ... no luck (i get the android with exclamation mark when i try to go into recovery)
acer recovery installer shows bootloader version 3.01
any ideas ?
thanks

First off, get your UID number just in case you need it. You can get it in the Dev forum (sticky). Always have your UID written down somewhere.
Then go to the "all files" Sticky thread in the Dev forum. Where they have all the Acer roms and updates.
Download 2 or 3 of the a500 ICS Update files. These are full update files.
Decrypt them if needed, then pull the update.zip out. Copy to EXT SD Card, and boot holding Vol+ and PWR till you see the text about installing, then release.
Might have to try more than one, but eventually one should install. These are full update roms, not patches.
Should give you a stock ICS. Hey, check your camera, might start working again

[Q] Unbricking / Installing stock ROM

I am trying to debrick my brother's A500 tablet.
He says while he was watching a youtube video, the tablet rebooted by itself and it got stuck at the Acer logo.
He has no idea about the version of android he was using or the bootloader. It was all stock.
And he doesn't know the CPUID.
I tried installing a bunch of FULL stock ROMS from:
http://forum.xda-developers.com/showthread.php?t=1816560
I tried to install:
Acer_A500_1.031.00_WW_GEN1 (ICS 4.0.3)
PB_G100W_4.010.01_COM_GEN1 (HC 3.2.1)
and
Acer_A500_4.010.38_COM_GEN1 (HC 3.1)
The only file I could install was the last one, HC 3.1 (The install bars did not move with the other ones).
However, with this one after reboot, I am getting red "Boot Verified Failed"
With USB-DeView, he can only see 11-digit serial number, is that an indication that his device was ICS from the beginning (he got it refurbished)?
It seems like I don't have a matching bootloader, is there a way to find out the version of the bootloader? Or install a custom bootloader in this stage?
Or any way to get the tablet back to working condition??
Any help will be appreciated.

[Q] Stuck on boot animation -- all ROMS

My Nexus 4 was previously running 4.4.2 ... I had a modified kernel patch (done via an app and I can't remember the name of it) and it was rooted. On occasion I would pickup the phone just to find out it had shut down. I would reboot it and it would be fine for days. One day it got stuck on the boot animation. It just wouldn't pass that point. Then the battery died (I assume) so I plugged it in via USB to both wall and PC and it would not charge. I had to put in on my wireless charging pad and it charged right up .. but still would not pass the animation.
Since then I have individually flashed each file manually from the newest lolipop ROM. Tried the nexus toolkit including most of the 4.X.X stock ROMS. Did a format and erase. Booted Clockwork Recovery and installed 5.0 from sdcard. (I can access the sdcard via USB on CWM). I flashed the kernel, Radio and bootloader several times each. I tried the Cyan ROM 10.x too
After the second attempt installing 5.0 (using the toolkit) I did get "Android is upgrading ... Optimizing apps" then it hung on "starting apps" and the animation continued for hours. I have had no other success since then.
I am at a complete loss. So I turn to the experts in hope of salvation.
Any idea what I'm doing wrong or what else I should be doing?

Well, here's a new twist. I'm able to flash 4.2 and 4.2.2 with no problems .. but 4.3 OTA and even manual flash will reproduce the stuck on animated logo problem.
I installed a sensor app and it seems like all sensors are working fine.
I remember that I was using the franco kernel before my problems started. Maybe I have a botched kernel. But I have flashed it when I did all the ROMs did I not?
What is the earliest kernel version that is compatible with 4.3, 4.4 and 5.0?

Does anyone know why I can't flash beyond 4.2.2?
Is there a way to systematically test each .img to discover the problem?
Also, even though I have USB debugging enabled, I can't use ADB to sideload at all. I keep getting ADB was not found. I can use ADB without problems on my nexus 5.

Same issue here. Could flash 4.2.2 and update with ota to 4.4.4, after that the boot animation stay's for more then an hour. Any idea how to solve this?

Just to share my own experience on similar issue..
my N4 was official Lollipop 5.0.1 unrooted & locked.
Unlocked & installed clockworkmod & latest official pa rom -> stuck in boot screen. (had done all resets etc )
full wipe & latest official CM nightly -> stuck in boot screen.
full wipe & installed full official google 4.4.4 image -> phone booted ok.
full wipe & install cwm & latest official pa rom (same as earlier) -> phone booted ok.
So my conclusion was that it had something to do with lollipop modem etc part, that didnt quite work with roms i tried to run.
BTW for some reason wasnt able to get adb sideload to work for me neither, so installed the factory images on fastboot / flash-all.bat

If you have a backup with USB debugging enabled, you could restore it and try to take a logcat while booting. This would make finding the culprit a lot easier.

Help me,, Cannot boot in to recovery

Please help needed!!
I'm stuck here for 3 days
Ok I'm going to tell everything I did,,
My Gionee E7 is indian version.
First I rooted my phone with kingo Root.
Than I flashed CWM chinese version.
I upgraded my system to kitkat and changed the recovery to stock.
I used it for a week than some how my music player and gallery were corrupted.
I don't have any rom so I download one but it was in chinese, flashed it to my gionee. than after rooting,,
I flashed the CWM, same I flashed weeks ago
Here my problem started :crying:
The CWM is not starting. I used recoery tool to boot into recovery after boot up it shows black screen. I used every method holding Vol+ and power button but the same result.
than I tired to get back to my stock recovery but it does the same.
flashed many times both recoveries but didn't worked.
I searched a lot and find a TWRP. I flashed it and wow it worked Finally I can boot into recoery mode.
Now I find the Nandroid backup of indian version. I made it a zip and flashed it through twrp.
My phone is back to indian version but its slow, not too much but its slow; camera, gallery and other apps take some time to open. I can't make or rcv phone calls. Now what i did is download the update form System update.
Now i got kitkat rom.zip but twrp failed to install it.
Some one on the internet was saying that its the problem with my Kernel. I have the latest kernel so CWM won't work cuz it uses old kernel and display drivers.
My
android version is 4.2.2
Kernel version is 3.4.0-svn2155
I also got TWRP for lolipop,
and I patched binary_update in my kitkat rom too but TWRP can't flash it

Hello my friend, please help me.
I am trying to flash stock inidan rom 4.2 but.. I installed all CWM for E7 found on the internet and I am getting black screen. I managed to Install TWRP but TWRP cannot flash the rom that I need to flash. I flashed a chinese 4.2 but is piece of garbage..
gngc-download-tool said that the com port is closed.
I have windows 64 is this the problem causing gngc not working?

No its not, it is working on 64bit windows very well.
In TWRP factory reset and format system and data, than install
Chinese 4.2 ROM. After that boot it and try it again.
It should work!

Help
I just rooted my gionee elife e7. Flashed the chinese recovery which seemed to be the only one which would be compatible. But, while changing a few setting using pimp my rom, the software just stopped working. Errors keep showing up on the screen - "system.ui is not working", "android app is not working", I cannot even go the settings because "settings is not working". Third party apps still seem to work, so, whatsap and stuff continue to function. Doing a factory reset or flashing firmware again seem to be the only viable option.
But, when I try to load up the bootloader using the power and volume keys, it gets stuck on the screen showing the gionee logo and it reads 'fastboot mode' in the bottom left hand side corner. So,
a. can you offer any advice which may be useful ?
b. can you share the link from where you got a TWRP recovery which will work on the Elife ?
c. do you have any idea what exactly went wrong here ?
Any help you can provide will be appreciated because, it's my mausi's phone and I will have a very tough time explaining what really went down here.
Regards,
