I'm trying to flash the Vegan-Tab ROM on the gTablet I just got. I installed the 1.1 bootloader and CM .8. Or, I think I did. When I power up using power and volume +, I never got a menu when I tried installing these. The green box just popped up, so I assumed it was installing, then it rebooted normally. So when I try to boot into recovery mode, it does the same thing, and the menu never comes up. Did I do something wrong?
I have a similar problem ... loaded CM7 safely, was working for a while, all good. Decided (stupidly) to update recovery from CWM and now, nothing I do can get it to boot into recovery! Not manually, not through software (boot to recovery) options...
Also, the viewsonic birds screen is gone, so I assume something bad happened to the bootloader.
Still boots to 'production' cleanly, just not recovery or bootloader. Help!
FIXED - had to nvflash back to stock and start over!

After flashing the latest ROM I was messing around with (WajkIUI 2.1.6) the phone would crash and reboot within 30 seconds of booting up. The previous ROM that was running was FAUXMIUI_RG2xV2.0.0 (01/08/2011 [v2.0.0]OVERCLOCK) that was stable except for when I’d turn wi-fi on after being off for 8 hours or so phone would reboot.
I figured I would boot into ClockworkMod Recovery and restore one of the nandroid backups, I tried booting into recovery I found out that I could not. When I hold the volume down and press the power button I see the screen that says software update (like when flashing with OneClickRecoveryFlasher).
Whenever I flash a new ROM I will Wipe data/factory reset, wipe cache partition, and then wipe dalvik before installing zip. I’ve always run cyanogenmod nighties; FAUXMIUI_RG2xV2.0.0 was the first MIUI ROM I’ve used.
When I run OneClickRecoveryFlasher, I do not see any errors on the command prompt so I am assuming it was successful, or at least thinks it was.
I tried to Restore LG G2x Stock Recovery using OneClickRecoveryFlasher and then flashing v5.0.2.0 and still no ClockworkMod Recovery, also tried v4.0.1.5 and still no ClockworkMod Recover.
I then tried http://forum.xda-developers.com/showthread.php?t=1248644 and with that I was able to get back to stock 2.3.3, tried to use OneClickRecoveryFlasher to flash ClockworkMod, still no go.
I tried LG Mobile Update and that proceeded to install something, not really sure what the update was, after the update finished, phone rebooted into stock 2.3.3. Shut the phone down and tried to flash ClockworkMod and still nothing.
I did a hard reset following http://mobilephonerepairguides.blogspot.com/2011/04/lg-g2x-hard-reset.html
I also tried http://forum.xda-developers.com/showthread.php?t=1183168, that got me to stock 2.3.3 but I still could not boot in to ClockwordMod Recovery.
I’m having a hell of a time wrapping my head around what I screwed up. Did I somehow destroy the recovery partition, is that possible? Any ideas what I broke and how to fix it? Can I used adb to view the partition table, would that tell me if something was corrupt?
Any help and ideas would be appreciated, I have tried doing my due diligence and I apologize if I missed something obvious.
Thanks,

Faux never made a miui
Did you nvflashed recovery? If no then do that first.
NVIDIA NEVER AGAIN!
If you did the LG Updater it returned your phone to stock everything, including recovery. You need to use NVFlash (One Click method okay) to reflash CWM and then you should be good to go.
When the phone is completely off, hold volume down, then hold the power button and don't let go of both until the second lg logo.
If you hold volume down too early it'll give you the software update screen.
Well that's embarrassing, thanks buru898 that did the trick and got me into CWM Recovery. I never remember holding the power button for that long but it worked and I'll remember that for next time.
Thanks

Sorry, I only wrote in the actual zip file name, I meant RG2x-MIUI v2.1.6-MultiLang/Powered by Faux Kernels CM v0.4.8(01/08/2012)[v2.0.0].
Thanks
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)
I'm having issues getting recovery to work on a Verizon version xoom. I first flashed CWM version 4.0.0.4. The first time I tried to boot into it, it was stuck on the android with the red triangle for a long time before finally getting into it (coincidentally when I was hitting the volume key, don't know if that's related). Anyway, since then I haven't been able to get into it. It will be suck on the red triangle screen for a minute or two before rebooting into the stock rom (I'm running stock ICS). Since then, I've tried flashing the new TWRP 2.2.2 or whatever version it is and it has no effect. It's still doing the same thing. Any clue what's wrong?
So what I'm reading is suggesting that the android guy I'm seeing is the stock recovery. I'm not sure how that's happening. I'm installing the recovery using fastboot on my PC and being in the bootloader on my xoom. The prompts on both appear to confirm success.
I haven't tried this yet as I'm at work, but I think I've got the issue sorted. The following is what appears to be happening from what I've read.
1. I've still got the custom recovery stalled. When the Android guy pops up, one needs to press volume up to enter the options. Otherwise, it reboots.
2. The recovery flashes are taking because I'm booting back into the rom after a flash. The system's built in recovery protection is re-flashing the original recovery at that point.
3. To make my CWM/TWRP/whatever flash stick, I'll need to power down and then boot directly into the recovery.
I'll post again tonight to say if this works. Hopefully this thread can help out others who have the same issue.

fastboot flash recovery recovery-Tiamat-R4c-100611-1150-cwm.img
I rooted my MT4GS a few months ago but stuck with the stock ROM. I decided I wanted to try out the CyanogenMod 9.1 ICS ROM. I followed the following steps:
1) Installed ROM Manager.
2) ROM Manager indicated a newer version of ClockworkMod Recovery and I installed it (5.0.2.7).
3) Using ROM Manager, did a full backup of the current ROM. All went well.
4) Using ROM Manager, downloaded and installed CyanogenMod 9.1.0 stable-doubleshot. I specified to wipe the data and cache partitions. The installation seemed to go normally.
When the phone rebooted, it was stuck at the logo screen. Had to remove the battery to turn it off. Tried a couple times, still the same.
Since I had the backup, I decided I would use CWM to restore the old ROM.
When I boot into recovery mode, it shows CWM 5.0.2.7, but whatever option I try to choose from the recovery menu, The screen just goes blank with the CWM logo in the middle and nothing else happens. Hitting the power button returns me to the menu, but no option works, even power down or reboot. It just goes back to the CWM logo again and I have to remove the battery to shut it down.
So, I thought I would try using fastboot to flash the ROM again. When I boot the phone into the boot loader and select fastboot, then plug the phone in via USB, nothing happens. Windows does not see the phone and ADB or fastboot don't see it either. It's not a driver issue, as the computer is still setup from when the computer was rooted and I connect the phone all the time with no problems.
When the phone is off and plugged into USB or the charger, I still get the charging light, though it goes off after about 10 seconds, then comes back on and cycles like that.
Is there anything I can try at this point, or is my phone bricked? It seems like I followed all the steps correctly. Is there an update.zip I can put in the root folder and see if it picks it up?
Any help would be appreciated.

Ok, after rebooting Windows, I was able to get the USB connection to the phone to work in fastboot. It seems I missed the step described in this thread:
http://forum.xda-developers.com/showthread.php?t=1508556
which states with S-ON you must flash the boot.img separately. I did that via fastboot and the phone boots into cyanogenmod now.
However, I still seem to have the issue with clockwordmod recovery. As long as I do the recovery functions from rom manager, everything is fine, but when I manually boot into the recovery menu, I get the same behavior of any choice from the menu just blanks the screen except for the CWM logo and nothing happens. I tried reflashing the recovery image using fastboot, but still no go.

This is solved also. Seems on the MT4GS, the trackball is the selection button. The power button appears to only be a back button.
What a thread! Two nicely phrased problem definitions, two well explained solutions, and all from the same guy. Sorry we weren't able to help directly, but you obviously found the answers you needed elsewhere in the forum. And you updated the title as well to show it was solved. Thanks.
I scoured the forums, but have not been able to find out what I can do to solve my problem. So here it is.
I rooted my phone (to play around with some settings, what have you) and flashed TWRP recovery onto it. I got an error msg when booting up, so I decided to push an original recovery back onto the phone, because it wouldn't go to TWRP. I followed a guide (which I can't find now) to push back a stock version of recovery and it failed. My phone would boot normally just fine, but when I tried to go to recovery it would loop.
The OTA update came today, and dumbass me pressed continue (not thinking) and now I am stuck in a boot loop, and cannot get out of it.
Cannot get into recovery.
Cannot get into download mode.
Got any ideas?
Thanks
Same Problem
I have pretty much the same problem. Please help!
well without recovery/download mode working or the phone being in fastboot mode there really isn't much that can be done, you can always try to claim on warranty
boot loop
So, let me get this straight. If it failed when you tried to install the stock recovery, then you still have the TWRP recovery right?
I ran into a boot loop problem earlier when I tried upgrading TWRP. I just couldn't access my recovery so here is what I tried:
Code:
Turn your phone off.
Press volume down and power button until the LG logo comes on screen
Let go of both buttons
Hold the volume down and power buttons again until you see the "hard reset screen"
Press power once and then power again to confirm. The screen says it will reset your device but it will not as long as you have a custom recovery installed.
Your custom recovery should appear on screen.
Try the steps above and see if you can get into a recovery. Once you do maybe try resetting. Hope that helps.
