For the second time, I was attempting to downgrade from ICS to HC last night and ran into a bit of a problem. Here's what I have and did:
TF101 with 9.2.1.24 US 20120503
I rooted with PERI-0.4 (found here) and that worked fine. I then installed Super User and Recovery Installer. Started Super User, closed, then started Recovery Installer and clicked the button. It did its thing and rebooted. I had the zip of the latest released HC built on my microSD card and booted into the recovery console (Power + Volume Down). From there I wiped the cache and installed from the zip file. It did its thing for several minutes before saying done.
I then clicked reboot and instead of getting to the android guy with the green progress bar (like it did last time), I get to the revolver screen where it stays there for a few minutes and reboots..and repeats. I left it overnight and still doing it. I tried getting to the recovery console again to try and reinstall, but when I do that (power + volume down), The android logo comes up with a yellow triangle with an exclamation mark in him. It might also be worth it to add that I can't turn it off unless I hold the Power + Volume Up buttons. Holding the Power or the Power + Volume Down do not turn it off, it just reboots.
PLEASE does anyone know what I might be able to try?
can u cold boot from linux?
Thank to the wonderful people over at AndroidRoot.mobi and their custom NVFlash tool, along with using the latest stock ROMs, I was able to flash the stock rom and now have a full functional tablet again, AND as a double plus? Its at HC
Why did you use Recovery Installer after PERI though? What PERI does is install custom recovery xD
I did because when I tried to install the HC zip file in the recovery manager, It said it was unable to do so (something like directory doesnt exist IIRC) so ran Recovery Installer and then it was able to recover from the HC zip file....before crapping out on me.

I just exchanged my g tablet at office depot and before I put clockwork recovery on the new one, I decided to update it to see what changes were made to the stock g tablet shell as I have been running vegan for a while. The tablet boots and runs as it should, but I cannot get into recovery mode. I hold power and volume + on boot and it says Dectect recovery key and it looks like it is going to boot into the stock recovery but then it goes to a screen where it looks like the tablet is updating (as if it was installing a new firmware) for about 10 seconds, then reboots into the OS...any ideas as to why I cannot get in?
thanks

I don't think the stock firmware's recovery mode has anything like the Clockworkmod's menu. The stock's recovery mode basically looks for a recovery folder and an update.zip in the internal sdcard's root directory and that is. Since there isn't a recovery folder and a file named update.zip in your internal sdcard's root directory therefore the behavior you observed was correct when you tried to boot into recovery mode. You will have to install the Clockworkmod to give you a more advanced recovery tool on the gtab.
Follow this link by scsione889 to install Clockworkmod on stock rom.

What you are describing sounds very much like a successful update via the standard recovery console.
• Are you sure your update didn't work?
• Did you have the update.zip in the root of your sdcard and the command script in the recovery folder?
• What version do you see in the settings screen?
• Did you know that you may need to wipe user data to see the new UI even with the latest ROM?

thanks for the replies
The strange thing is, I have done all of these things. I just did the same steps I did with the old tablet and cannot get it to work.
I will reread all of the tutorials and follow your steps..maybe I am missing something? I just dont see what I am missing..
Here are my steps.
DL clockworkmod.
Put it in the root of my microSD card.
power on device holding PWR and VOL +.
Wait for the viewsonic splash screen to show detect recovery buttons.
Release buttons.
Then gTablet splash screen appears.
then stock android update screen appears as if it is updating something.
about 10-15 seconds later, device reboots to regular OS..
I have also tried these steps putting the clockwork files on the root of the tablet's storage with no luck...It is crazy that I cannot even get into the stock android recovery. I have never had an issue with this as I have had a Droid, Droid X and Droid Incredible and have already modded on tablet..
The only thing that has changed between my tablet and my returned one is the OS version. This one shows 3389 in the settings and I know I never updated my other one.
Did something change with OS 3389?
I successfully rooted my 3G XOOM today, installed ClockworkMod Recovery, but can't get into recovery mode! No matter what I do, I get stuck at a screen showing "Entering Android Recovery Mode Reading ODM fuse:1".
I waited for several minutes, and nothing happened. I tried to format th SD card, but didn't work too.
If I manually reset the Xoom, it stars normally and everything works fine.
Did you wait 3 seconds at the Motorola screen and hit volume down and then volume up? Were you able to get in it before?
Yes, i did that, but it gets stuck at that same point. And no, I never tried to enter recovery mode before.
How did you flash recovery the first time. Did you flash or push? Have you tried to push the recovery?
The first time I flashed recovery using the button inside ClockworkMod, and CWM said it went fine.
How can i push recovery? Using adb?
Got it! I don't know what caused the problem, but flashing the newest version of CWM recovery using this guide solved it!
Now I can proceed updating my Xoom to HC 3.1.
what worked for me was volume-down volume-up while holding down the power buttom ( like a shift key )
hi all i have a T-mobile G2X and im trying to root this phone so... i try to flash CWM using NVFLASH and everything goes according to plan but once i try to boot into recovery by pressing both volume up and down buttons nothing happens. Once i flash stock recovery phone boots and everything is back to normal but once i flash either version same thing happens again. I tried searching but couldn't find a solution. So if anyone can help me or point me to the right direction i will appreciate it.
You boot into CWM recovery by holding power + volume down (do not touch volume up). Hold the keys a good 10 seconds and wait for the fancy LG logo. Once you see the fancy LG logo (not plain white) you can let the keys go. You will then boot into CWM. You are just pressing the wrong keys. Don't boot that way into stock recovery as it will do a factory reset on your phone.
I seem to be having the same problem, except that my phone only shows the s/w update screen and wont revert back to the stock recovery when i try. nvflash just leaves my phone on the update screen for hours. it will boot up normal if i pull the battery and put it back in, but it only shows the s/w update screen when i try to boot into recovery. any thoughts?
To boot into Clock Work Mod Recovery, you press and hold the "volume down key" and the "power/sleep" button at the same time.
Hold the buttons all the way through the Lg boot logo. After a short moment, you will see a distinct "purplish" bluish glow to the logo. At that time, release both buttons.
You will boot into Clock Work Mod Recover and ready for flashing
or use the Terminal:
$su
#reboot recovery

This command does not work on the P999. Recovery is not on the standard partition and this command will only reboot the phone. To reboot into recovery (if you have CWM installed on the physical recovery partition and not installed by ROM Manager) you need either Weapon Rom installed, which has this built in or there is an app on the Android Market written specifically for LG 2X/G2X devices that knows where the recovery is installed and can reboot into it. On some G2X (P999) models it says not compatible because of the way LG wrote the build.prop but instead of saying "Ok" which closes the program you simply use the back key to get to the main program screen and it works like a charm.
This app is also preinstalled as a system app on my roms.

Thank You everyone for ur help. Ive figure everything out and im now running MIUI ROM.
After I updated my (unrooeted/locked) Nexus S (9023) to 4.0.3 I wanted to try the 4.0.4 upgrade. After the 4.0.3 the recovery mode lost the backlight, so I figured the it was a good time to root.
I tried this one-click script to unlock. It worked and I installed CWMR and flashed the 4.0.4 upgrade. After a reboot the phone had ICS 4.0.4 and got root.
But not all is working. I lost the ability to get into the bootloader by pressing 'vol down.' & 'power'. The phone just starts normally.
The only way I can get into the bootloader, is to "reboot to bootloader" from a command line. If I choose recovery, I get a picture of an android at its back with a red ! (2105.dk/temp/img_1161.jpg). After two minutes it automatically reboots. What has gone wrong? What does it mean? And how can I fix it?
I'm new at this, so i'm out of ideas
try Vol up + power
Ahhh... now i'm feeling a bit stupid
Okay, i'm able to get into the bootloader, but the problem with the recovery still remains. (what does the picture mean? - 2105.dk/temp/img_1161.jpg)
I've tried both CWRM and TWRP. They seems to flash with no errors, but i still can not get them started from the bootloader (fastboot mode?).
Not sure if it's what you are looking for since I can't see the picture you are talking about but I think it's the recovery "security" screen. When you are there press power first and maintain it to press vol up, you should now be into the recovery...
Also remember stock rom has a script that overwrites any custom recovery with stock recovery each time the rom loads.
Yes, pressing [power] + [vol. up] at the recovery "security/error" screen, starts up a recovery.
I also didn't knew that the stock ROM overwrites the recovery. I never seen it mentioned any where else.
Thanks for the hints.
Okay, after learning how the stock OS trying to reinstall stock recovery, I managed to rename /etc/install-recovery.sh to *.bak
Now the stock recovery stays away, and CWM recovery stays on permanent.
Also, the error screen doesn't show up any more. (never found out what it means)
Hi, i have a start 101 tablet with a Cortex-A9 cpu, a WM8850 chipset and a Mali-400 GPU and i do have root, it has android 4.0.3, im not very good in these things but i wanted to install google apps on this tablet, i already found a site that gives some links to some zip files for every android version, but i don't know how to install them. The site that gave those zip said that you need to boot into the recovery of the device and press install from zip, but the problem is that my recovery doesn't have any menu on it.
So 2 days ago i tried finding a way to boot into the recovery, holding the power button and volume up do not take me to the recovery, they take me to a screen which says "do you want to do system recovery? press power button before 10 seconds to confirm" and if i press the power button the tablet factory resets, if i wait 10 seconds the tablet shuts down, i also tried holding the power and volume down buttons but they just took me to normal android.
Now yesterday i found a way to boot into the recovery by using an adb command or by using an app called "Reboot manager ROOT", but the problem is that when i use abd or this app and reboot to the recovery, an android robot with a red triangle appears without any menu on it, and searching this on the internet i was told to basically press power and volume up / down untill a menu appears but i can't get this menu to show up, and since there is no menu if i hold the power button to reboot im stuck into this boot to recovery loop unless i factory reset which works and takes me back to normal android, so then i was thinking that maybe the recovery in this tablet does not exist but is that possible? im not very experienced with this but i also found out about custom recovery yesterday, so after like 5 hours on the internet i found a cwm recovery for my chipset and i saw a video on youtube that said that if you had a twrp/cwm recovery for the same chipset of your android device you can make a custom recovery for your device, the video i followed is this:
so i made this custom recovery img file now but how can i flash it? or can i just use the recovery that is already into my tablet to install the google apps?
because i searched the internet a bit and it seems that for flashing a recovery you need to go to the bootloader but i can't access this thing for some reason, power + volume down takes me to normal android so then i tried adb reboot bootloader but it also takes me to normal android, then i also tried the same app i used to reboot into recovery (reboot manager root) but pressing the reboot to bootloader buttons also does not work (it asks for root permission, i press allow and then it reboots to normal android) same with the reboot to download mode button, then as a last attemp i downloaded an app called "flashify" which basically allows to flash recovery, zip and etc, so i first tried to flash the recovery but pressing the button choose file made the app freeze, so then i tried the flash zip option to maybe flash google apps without recovey, but after choosing the zip it gets stuck at downloading 92% and the app freezes and it doesn't seem to have installed the google apps, do you know if there is any way to boot into this bootloader to flash this cwm recovery or maybe any way i can get the normal recovery to work?
thanks for the help!
