[Q] Boot loop help - G Tablet Q&A, Help & Troubleshooting

haven't had time to play anymore and looking to wipe and sell my gtab. I had C7 running, so I went to settings/privacy and wanted to remove my account, saw a /dev/null popup, but after rebooting, I saw the birds and right into recovery and that's where I am stuck. There are other posts, none of which I could really follow, but here is my scenario;
On boot I get the birds, top left "booting recovery kernel image". I tried a wipe, install from zip and 2 or 3 numerous ROM's that had worked in the past, so that is where I am stuck. The bottom of CWM shows;
ClockworkMod Recovery v.3.0.2.8 (GTAB 1.2 and NI Adam rev5)
I don't have my old windows VM that I used to flash 1.2, but I really don't care what ROM I go with, custom, TNT, etc. so just need to know how to get back to a bootable system.
Thanks.

Your problem description is not very clear. Is your gTab always booting into recovery? If yes, then, see this thread.

[Q] [Solved!] HELP!! How to unbrick my tablet? - fix inside

I am one of the lucky ones who got their tablet from woot/amazon for $280.
I got it in yesterday and absolutely hated the Tap Tap interface.
Naturally, I wanted to install a new ROM. I could only get the TnT Lite to install, but still not what I wanted. I tried Vegan and G-Harmony and I got the dreaded 3 bird screen. I downloaded and successfully installed 3588 and rebooted it. I noticed the ClockworkMod is no longer on there, which is no problem.
I followed the directions to install Clockwork and ROMS from here:
http://forum.xda-developers.com/showthread.php?t=865245
I, for some reason, decided to install Vegan again w/o clockwork installed.
I mounted the internal memory card, copied he ROM over as update.zip with the Recovery folder and the command file set to install from SDCARD. A reboot later and now I am stuck at the 3 birds...
I was able to do the Power +Vol and get the "Recovery key detected" message and it seems to load something, hitting the home button gives me the verbose which indicated that it was trying to install something off SDCARD2.
I have tried 3588, clockworkmod and Vegan as update zip on the external SD card with the Recovery folder command file pointing to SDCARD2.
When booting into Recovery, the verbose says: "FORMATTING MISC... REBOOTING..." takes about 4 seconds to complete, reboots and back to the 3 birds screen.
So, how do I [email protected]#$ myself here?
UPDATE!
I got my tablet to boot into CWM!! I ended up putting the MicroSD version of CWM and held down the Power +Vol longer that normal, saw the Android text and it installed the update.zip.
I tried in vain to boot into CWM, but it would re-install the update.zip. *Head smack* took out the SD card and now it boots into CWM!
Now, to try to install a ROM w/o those damn 3 bird screen...
Bootlogo not part of a ROM
You can replace the birds logo, but it is not part of a ROM. Search for replace boot logo, but make sure you know the correct partition to push your custom logo too. Read the entire thread when you find it first. There are tools out there that will let you back up your partitions, I highly recommend doing that first. Search for backup bct and look for PooR's thread and tools.

The boot logo is not my issue, it's just that it does not go past it no matter what non-TnT ROM I try to install.
I just want to install anything other than the factory OS or a modified factory OS (no disrespect to the dev who made TnT Lite).
I started another thread on my troubles getting a new ROM on there:

[Q] Help! G-Tab won't boot into Recovery

Hi, I just brought my G Tablet and I have downloaded "ClockworkMod_Gtab_v08.zip" and copy the "update.zip and "recovery" into my internal SD Root dir.
I boot into recovery mood and ClockworkMod install but after reboot into recovery mood again, the screen freeze in "Booting recovery kernel image" and don't go into ClockworkMod screen (for more then 10 mins and have try rebooting it a few times).
The G Tab can still boot up normally in to TapnTap, everything seem working find and I can connect to my computer using USB cable. But just can't boot into recovery.
I wanted to install new rom, how do I make boot into ClockworkMod screen (recovery)?
Any help is welcome.
Thanks
Take a look at the recovery script and make sure it says sdcard vs sdcard- ext that's the only thing i can think of right now that May do that.

This is the symptom of installing the wrong cwm. You're on the 1.2 branch but you put the cwm for the 1.1 branch. You hosed your recovery. Go to my website and use code red in the "start here" page to recover.
Same thing I happened to me. I bought mine off Woot a few days back and it came with 1.2 bootloader (4349). No matter how many times I tried, I could never get back into recovery. Here are the steps I did to fix that:
1. You need to do nvflash to recover your stock recovery (http://forum.xda-developers.com/showthread.php?t=861950) - I followed all steps in the "Installation" section.
2. After this, you should now have your stock recovery back. You're going to need to downgrade manually to 3588 - Just follow the "POST NVFlash" section on that same page.
3. Once you're done downgrading, should be able to install CWM without issue.
Problem solved!
Thanks goodintentions you save my G Tab, it works!
And now it can boot back into ClockworkMod recovery mode.
Your website is very good and informative. Good job.
Thanks again.
Thanks "goodintentions", You saved me as well
Followed your post and it worked.
Good information...thanks for the help!

nvflash for dummies not working
Bro I connected my gtab to my computer in apx mode and my computer couldn't see it. Went to device manager and apx device was absent. Needless to say connecting my gtab to the computer was as far as I could get. If it helps any, I'm currently running bottle of smoke. Where I screwed my tab up is when I opened up time manager and it had an ota update for the recovery I was using.... Shoulda known better than to select advent vega for the device when it was running on the 1.2 branch recovery. Any tips? I wanna change my time but I need my recovery up n running.

Gtab Stuck in Reovery Boot

Hi All, I have attempted to flash clockwork mod onto my G-Tab using This guide. I put the update.zip into its proper place in the internal sd card, and then booted to recovery where it looked as if it installed and then it rebooted, I then went back into recovery where now it is stuck at the Viewsonic Birds screen and says in the corner "Recovery Key Detected" "Booting recovery kernel image". It never made it to clockwork. I know that it is not bricked, I can still boot to the normal OS but would like to get it to clockwork and then to a custom Rom. Any Suggestions or help for this?
I have done several samsung captivate root's and flashed them with custom Rom's so this is not my first rodeo.
Thanks
Sam
What bootloader are you on?

That CWM version is for 1.1 bootloader. Boot to Android, go to Settings, About & see which TapNTap version you are on. If it starts with 1.2 you are on 1.2 bootloader. If it starts with 1.1 you are on the 1.1 bootloader & you flashed the wrong version.

Issue with recovery freezing

Recently decided to try and switch over to CM10, and have been having an issue with recovery. Both of the latest CWM and TWRP recoveries freeze for me after booting into them. The only recovery that works for me is the one that is flashed with the old app by Indirect but that flashes a really old CWM recovery. The recoveries that I have tried flashing are the ones linked to in the http://forum.xda-developers.com/showthread.php?t=1877217 thread. Both http://celticstorage.co.uk/cm10/CWM_v6.0.1.5_emmc.zip and http://celticstorage.co.uk/cm10/TWRP_v2.3.1.1_emmc.zip are doing it. I have a 16GB that ive kept (rooted) stock forever.
What happens is i go to boot to recovery, go through cyanoboot to recovery, and then CWM freezes up and blackscreens after I try to wipe something or install a zip, TWRP just locks up immediately and gives me a black screen. Any help fixing this would be greatly appreciated.
Use this thread to install CWM, I'm not a fan of TWRP. http://forum.xda-developers.com/showthread.php?p=25786947 I used this and had no problems updating

This has been happening to me occasionally. I have found that when I get the black screen, pressing the Power button launches Recovery (CWM in my case). See if that works for you.
I now have the exact same problem. I've always ran off emmc. It says cwm 6.0.1.5 is installed. When I try to either wipe, or install zip-from-sd, cwm freezes then goes to the black screen. I cannot install any zips, so right now the tablet has nothing installed only a freezing cwm recovery it seems. I can use the power button to get out of the black screen and into cwm thru cyanoboot all day, but get nothing but these same steps reoccurring. Freeze, then black sod. I'm ready to try anything but cannot flash anything.
To the rescue
Ok, I have posted this on a different day. Try this with a blank sd card. Look at the bottom post called "Here is a video"
It a external boot cwm v.5 but you can copy this into your sd then flash and you have cwm v6.0.1.5 internal. Either way you have two ways to do recovery (external and internal):victory:

Well, I think I need to clarify more. Maybe somebody can help if I give more info. I've had cm7 running perfect, then decided to install cm10. I first flashed a cwm 6.0.1.5 zip to emmc. I did a factory reset via this recovery thinking my next move would be to flash the cm10 zip I'd put on the sd. No joy. This is where I'm at now.
In recovery it freezes and reboots to the "2 androids" screen with a sod. I hold power for 20 sec.s to turn off, then turn back on and get to cyanoboot fine. There, if it's allowed to just boot it freezes at the 2 androids. If I hold "n" to get the menu and recovery (6.0.1.5) it looks normal, will boot to recovery OK until anything is selected like the cm10 zip. It freezes before any selections can be finalized, and boots to that sod screen.
I know nothing of ubuntu! Sorta scared to go there with my limited knowledge. But will read up if it's required. Is it possible that this new recovery image don't play with what is currently on the sd? Is there anything I can put there that it may recognize in order to get a flash? Man, I'm lost!
Look pass the fear and go one step at a time, before you know it, your there.
It looks like you have already resolved this from this thread.
Ok, basically I'll go step by step.
1. Download ubuntu iso from ubuntu website (you can donate or put 0$ then download iso) and burn it to cd. 5 minutes
2. Stick the cd into a system that you don't plan to look at the video that is showing you the process and boot it up from a reboot and not from within windows. Select the left square which basically load the ubunbu from cd but does not install anything to your hard drive.3 minutes
3. You can view the whole video but I would skip to the section in video (3:28 watch to 4:43, 6:56 watch to 8:06 ) where I mentioned the setting the two flags in your sd after quick format fat32 and extracting the four files into your sd within ms windows platform from the post . I did this with a normal mini sd card adapter and not the usb stick adapter he used in the video. Since you are doing this to a blank mini sd then there really nothing to worry about since it is blank in the first place. 2 minute
4. If you had your apps backup with titanium backup then it still will be on the main mini sd and not the one that working with for this recovery.
5. I notice you did not mention wipe dalvik cache from your post. You should always wipe dalvik then wipe factory then do a single flash to test boot up.. You can flash gapps after a successful boot up into jellybean. (here's a video showing that I'm using external cwm v.5 even though its recommended to use v.6 .) You can always use cwm v.6 on your next cm10 test rom or use cwm v.6 to reflash to same rom once a successful boot up have been obtained with external cwm v.5. This purpose is to get it running on your nt.
6. Be patient for the first boot. Should not be more than 5 minutes max. It will look black then load. If it boot loops then wipe dalvik then wipe factory and do a single flash to test boot up again.
This will at least get cm 10 flavored rom on to your nt.

Got it back! Thank you for your help & patience. Also for the timely responses. I now have a bootable "recovery sd card" for curing these type problems. I've labeled it & filed away for any future borks of this kind! And I have cm10 up & running stable.
Thank you!

[Q] will not boot into recovery

Hi,
I have a rooted (using Indirect's method, I believe, with help from Albert W.'s video) Nook Tablet 16GB. I'd like to try a custom ROM and installed GooManger (1.2.1). I can download a recovery file (openrecovery-twrp-2.3.1.1 -blaze.img), and it says it installed it, but when I try to boot into recovery ("Reboot recovery" option) it just reboots normally. If I try to browse compatible ROMs, it says "No roms were found".
Googled but could not find an answer. I would appreciate if someone could point me in the right direction!
Thanks,
Pat

I think you're trying to use the wrong recovery file. Try downloading CWM or TWRP from the links listed in the first post of this thread -- I've used both with no problems on my NT.

Removing CM9
HELP! I installed CM9 on my nook tablet 8gb and I am not happy with it. I want to take it back to stock so I can load CM7. HOWEVER I cannot find a single website with this information. I keep trying to power it off and then hold the power and n to no avail. The cyanoboot menu just loads and I cant load any of the ROMs. Its really pissing me off and I would like to just get rid of this os. Can anyone help?

You don't need to go back to stock to downgrade from CM9 to CM7. All you need to do is boot into recovery and flash the new ROM. With that being said, it would be well worth your time to start by installing Titanium Backup and backing up your system before you do anything else... That will let you restore any apps you've downloaded and want to keep (along with their settings and data), which will eliminate one headache after you flash the new ROM...
Review this thread from Lavero.Burgos about installing a customer recovery on your tablet. You've already got one installed if you're running CM9, but the thread has got lots of really good info, and if you have the Clockwork Mod 6.x recovery installed, you need to replace that with Clockwork Mod 5.x to flash CM7.
Next, check this thread from Celtic Web Solutions. The link to the internal CM7 ROM is in the first thread, along with the instructions for installing this ROM to your emmc (internal) storage.
Now, when you start you tablet, instead of holding Power + n to boot into recovery, wait for the Cyanoboot splash screen to open (the one that says CYANOBOOT, not the animated CM9 splash screen), then press and hold the n button until the boot menu appears. From here you can select to boot normally into CM9, into your internal recovery, or into a recovery.img loaded on your SD card. Select one of the recovery options, and you should be able to do a nandroid backup of your device, then install CM7. Since you're changing to a completely new ROM, I strongly recommend that you do a factory wipe/reset as well as wiping the cache partition and Dalvik cache.
NOTE: There's a big difference between an Titanium Backup backup and a Nandroid backup! You'll want to do both as you go through this. Titanium Backup will take a snapshot of your apps (including the settings and data associated with them) that you can restore after installing the new ROM. Super helpful, since you don't have to re-install everything from the Play Store, nor do you lose data like savegames, etc. Nandroid runs from recovery mode, and will do a complete image of your system, including the ROM. It protects you in case you run into a major problem while flashing a new ROM -- it's saved my life a couple of times...
