Two times now, once before, and once after flashing a new rom, I have been stuck in a recovery boot loop when I select "reboot recovery" from the advanced menu in CWM.
When I "reboot system now" the tablet magically goes back into CWM recovery. Without any keys being held, I see the message "Booting recovery kernal image" on the Viewsonic Birds screen.
Is "Reboot Recovery" a fatally flawed menu option in CWM?
More importantly, can I recover the tablet short of an NVflash (which is how I recovered the first time)?
I've tried holding down power+volumeup. I have run a keytest as well, all keys work. I feel like there must be a simple way to stop the tablet from rebooting into recovery? WTHelp?
Same issue here. Anyone have a solution?
You can go back into the CWM recovery menu and try to "Fix permission", if that doesn't work, "Clear Cache/User Data", if that stilll do not work?
Repartition 2048/0 and then mount USB, load the ROM and reboot
simpler?
I have the clockwork mod recovery loop. Going from 4349 to Flashback. None of the above mentioned suggestions have worked. I am not ready to try NVFlash yet as I >think< that SD card issues could really screw the Gtab if I might have one of "those" sd cards installed.. The ROM loads just fine, but reboot system just goes back into CWM recovery.
Help!
Try erasing the "misc" partitition (or the "bootbmp" partition as need be) as described here.
Do the same for the "cache" partition.
This has happened to me twice, I just nvflashed and it worked perfectly again. This is probably the only sure way you can get your tablet to boot to android again.
Interesting. I have not seen this problem, however I seem to have the opposite! Selecting "Reboot Recovery" either from Quickboot or the system shutdown menu (when I press the power button), just reboots normally. It will not boot into recovery. The only way I am able to get into clockwork anymore is to do a reboot and hold down the volume+ key. Everything else works normally though. I wonder if there will be any updates to CWM. Do you think this is a bug in CWM or something flakey going on w/ the G-Tab?

Click to expand...
Click to collapse
After you select "Reboot Recovery" does the first splash screen--the ViewSonic birds--disappear?

I tried to install the ROM. but every time I press and hold Volume+ and Power, it shows "Detect a recovery key pressed" and "Booting Restore Kernel image", then gTab shuts itself immediately. Also, tried the Factory Data Reset, rebooted to the birds and turned itself off again.
The device is not bricked, but I just can't load any ROM.
Please help.

use the microsd CWM install and see if it works. If it does, you'll see the box with install progress bar. If not, then NVFLASH...

Thank you very much, it works!
To install the utility ClockworkMod is the key.
I followed the instruction for installing the clockworkmod on viewsonic gtablet. I placed the update.zip and the recovery folder in the internal storage. I reboot the tablet (power and volume+)
The box with the down arrow appeared, and then I pressed apply update.zip, and then nothing happered for a long time. So I reboot it and tried to do the same steps again. BUT now it stuck when I reboot it at "Booting recovery kernel image"
so what shall I do?????
Depends...
1) Does it always reboot to "Booting recovery image..." or only when you're holding the volume up key? If not... can it boot normally?
2) What ROM are you running?
Hi! i need help. i deleted bascially everything from my phone. I was in recovery and deleted system, delvik/cache and i can't remember the other boxes i checked. now my phone is on the HTC logo with the red letters and won't go further. is there any solution? thanks in advance.
Maybe its obvious at this point, but it should still be said: you should not wipe anything in TWRP, if you do not fully understand what it is, and what the result will be. Those options are under the "Advanced" wipe section for a reason.
Access bootloader by: holding power button and vol up until the phone reboots (may take a minute or so, in the current condition). Once the screen goes blank (but before the logo screen reappears) let go of the buttons, and only hold vol down, and do not let go until the bootloader screen appears. If it doesn't work, you just didn't get the timing right (either started pressing vol down too late, or let go too early) so repeat until you get it right.
From bootloader, select recovery. If it still doesn't boot recovery, go back into bootloader, select fastboot. Then fastboot erase cache; and flash TWRP again using fastboot.
Once you can get into recovery, flash a ROM (either put a ROM on SD card, or adb push). Then reboot, and you should be good to go.
All else fails, relock the bootloader and RUU to stock.
I'm a bit stuck here, would appreciate some assistance.
I tried to root my device (UMI Plus) by yesterday using 'SP Flash tool' by flashing TWRP and then installing SuperSU. That went fine, but after booting my Google Play Services kept rebooting rendering the device unusable. In an attempt to fix this I tried a "Factory Reset" via the Android settings menu which I guess was a bad idea because it started auto booting into Recovery... At that point no matter what I did I ended up back in Recovery.. Reboot to system, factory data reset.. all rebooted the phone back into TWRP recovery.
So I thought I would just try putting the default recovery back on the device again but whenever I power off the device and connect it to my PC it boots into recovery.. The phone needs to be powered off for SP Flash Tools to work. Tried loading recovery image via fastboot but the volume rockers don't work in fastboot so I can't confirm the action.
After some digging I read online that holding down VolUp + Power can 'force' into preload mode, which seems to have some success. I can see the device boot into "Preloader mode" in device manager in Windows, but it loses connection after about 3 seconds. So I did that with my SP flash tool ready and it seems to have erased recovery mode. Oops! Now whenever I try to get into recovery it just says "No command". No combination of button pressing, button holding, button releasing or anything will change this (This is the only answer I could find on Google!). Neither fastboot or adb can see the device either. It shows up as "MTP USB device" in device manager in Windows...
Is it doomed? I can't figure out what to do next...
P.S. The full ROM is available here but in RAR format.. which seems strange to me...

I just unlocked bootloader.
Then I installed TWRP.
Tried to backup all partitions, failed. Maybe because I didn't know the data password.
Rebooted into system.
Now I want to boot into TWRP to backup then wipe and install Lineage.
But it just doesn't work.
I select reboot from menu, then hold Vol-Up.
It shows the unlocked bootloader warning, then boots up system
I shut down and start again pressing Power and Vol-Up.
If I release Power when the bootloader warning shows, it again boots the system.
If I continue pressing Power then it does nothing else as showing the warning, showing black screen, over and over.
thanks
So what the hell?
The stock system does not offer a "reboot into recovery" menu?!
Solved it myself. Booted recovery via fastboot.
And that probably was the issue: I initially booted it via fastboot and did not install it ever.
Edit: no. Maybe TWRP was replaced by stock recovery automatically.
