[Q] Newb trying to fix his G-tab - G Tablet Q&A, Help & Troubleshooting

So heres my problem, had Vegantab 7.0.0 on a Gtab I just purchased online. I wanted the Vegantab on it because Ive seen it beeing used but have not done anything with ROMs prior to this.
When I got it, it was stuck in a Bootloop just rebooting the Vegantab screen.
-NvFlashed the tab,
-Now I got the Gtab and the birds as part of the loop
-Tried to reinstall Vegantab via SD card, Keep getting an error
What am I screwing up because this tab is about ready to go flying across the room.

Try repartitioning the sdcard while in clockworkmod recovery (which I assume you've installed to install VeganTab).
I've seen the Gtablet loop over and over at the bootanimation until that partition is repartitioned (2048 for first, 0 for swap).

I was able to load clockwork back on it but now am getting
cant mount dev block mmcblk3p1 Error
All I see is to change the command line? Which I have no idea what they are talking about

You better just nvflash and start with a clean slate. There's good guides on nvflash just search them.

Internal SD (mmcblk3)

NVflashing will probably not correct this problem. mmcblk3 is on your internal sd (2 partitions p1 & p2) which nvflash doesn't touch. The internal sd contains the /data partition & /sdcard partitions. I believe p1 is /data.
Two things to try (both accomplish the same thing...the first is the quickest).
1. Boot to CWM, go to Advanced & Partition SD, 2048, 0. This will attempt to wipe out everything on the internal SD & recreate the /data & /sdcard partitions or
2. Boot to CWM, got to Mounts & Storage & format /data & format /sdcard.
If that doesn't work, the resident expert on troubleshooting gtab internal sd problems is rajeevvp. If he doesn't chime in, you can PM him & he can have you do further diagnostics.

[Q] Vegan Ginger sdcard2 format command formatted sdcard and will not boot!

So I just finished putting the final tweak on a re-install of Vegan Ginger. My previous install had some issues with long boot times and the Gallery was not synchronizing with my Picasa Web Photos. The last step in the process was wiping the external SDcard which was complaining from Ginger since I formatted originally to FAT32 on my PC and was unsure of the "preferred" format for Android/Gingerbread. So I went into settings, and under sdcard2 selected "Erase". I then attempted to mount and got some errors regarding the sdcard was empty or not formatted, so I selected "Format". I attempted to re-mount again and got the same error. So I figured that I would give the CWM format a try and rebooted into CWM. I then selected "format sd-ext" and CWM complained that apps2sd did not exist. I then rebooted the tablet through the CWM main menu.
Somehow in this process my internal sdcard was formatted!
The next boot, Vegan Ginger displayed the G Tab Devs and Vegan Launch screen but would boot loop about 5 times until the screen went black.
I was able to boot into ClockWorkMod (CWM) and attempts to mount /data or /sdcard result in:
mount /sdcard
Code:
Can't mount /sdcard
Can't mount /dev/block/mmcblk3p1 (or /dev/block/mmcblk2p1)
(No such file or directory)
mount /data
Code:
Can't mount DATA:!
Can't mount /dev/block/mmcblk3p1 (or /dev/block/mmcblk2p1)
(No such file or directory)
I attempted to do a restore through CWM which resulted in a failure.
Any suggestions on how to get back to a running system? My guess is the following:
format data
format sdcard
The following information would be very helpful:
Is there any chance recovering the current system?
Is it possible to do a "system snapshot" of my tablet to avoid this issue in the future?
What is the preferred Android external SD card format?
Thanks!
Run nvflash from the dev section. There is nothing there to save anymore
I had this same issue with a 32gb micro sdcard formatted in fat32. After finally getting things back in order with nvflash/wipe/reload, Im hesitant to try again. Any idea on the cause or how to prevent it from happening?

In CWM, do a backup (this is the nandroid backup mentioned often here on xda)
When you boot into android, copy the backup file OFF the device, and onto a desktop PC, or a USB flash drive - anywhere but onto any storage that is on the gtab.
Repeat both those steps any time you're about to make major changes, or do any formatting, or otherwise play with sharp objects near your gtab.
When you screw the pooch, you can always copy your latest backup back to the backup directory on the gtab, and then restore from CWM. You may need to nvflash first to get the thing into some sane state, of course. But you'll have the image which will save lots of setup time after...

[Q] Installing a ROM using External SD Card

I recently made a mistake on my phone & got it stuck in a boot loop. I figure the easiest fix is to just wipe system & install a new ROM from the CWM Recovery Menu. My problem is I cannot access the external sd card.
When trying to navigate install zip from sdcard > choose zip from sdcard > external_sd/ it simply returns "No Files Found". I'm assuming because that's probably just a symlink.
If I go to Mounts & Storage and attempt to mount /sd-ext, I get "Error mounting SDEXT :!.
Maybe I'm going about this the wrong way, so any help would be appreciated. I'm still fairly new to the whole Android scene.
I should note that my USB Port is broken so using that is out of the question. I've already attempted twice to replace it (damn thing wont desolder), but that's a whole other bag of worms.. That I won't bother re-visiting unless it's my only option.

You install a rom with cwm through the internal sd, not external; so yeah, you're going about it the wrong way.
*tear* Just what I didn't want to hear.
a little help
you could try flashing a different kernal ie siyah pr cm9 these have different versions cwm included so you might be able to access your ext sdcard just a thought.
It depends on the version of CWR you have flashed. Whenever I run ICZen the version of CWR (5 something) that Deficient Development bakes in lets you flash zips from the external SD; very convenient.
Can the OP use DroidExplorer, and transfer a rom to the internal? I've not used DroidExplorer, but have heard it talked about.
Sent from my SGH-T959 using XDA
If there isn't a ROM on the internal SD card to install from recovery, and the current kernel version does not support install from the external SD. Then I would assume you would need to ODIN to stock.
Good luck!
Sent from my SGH-T959 using xda premium
Why can't you use something like Dropbox or Box and upload it from your PC, then download it to your phone and transfer to the sdcard of choice with a file explorer? Then flash away. In fact I just did this the other night bc I was too lazy to go to my PC and hook up my phone. I just uploaded it with my tablet and then downloaded it to my Vibrant.
Edit::: I just re-read your OP.
If I go to Mounts & Storage and attempt to mount /sd-ext, I get "Error mounting SDEXT :!.

This is NOT the external sd card. SD-ext is another partition that has to be set up on the sdcard with something like Gparted or MiniTool Partition Wizard. It is for when you do not have the standard Samsung 2gb partition or the /datadata partition set up. FWIW, I have never seen this particular partition set up in the Vibrant.
I can't remember what the actual Mount option is in CWR but I definately know this is NOT it. Not sure if you remember seeing it or not but when you do a Nanadroid backup, it will always skip the SD-Ext part b/c there is nothing there. This is more mainly for older phone that were running Eclair and did not have native App2sd support. It was used as a hack to force that support.
i think go to a shop get your USB port repaired and get back to STOCK if you dont have any rom on your internal sd or do a (wipe cache etc etc) so that the phone will run on the ROM's kernel

[Q] Talk, Trebuchet errors. Explain cm10 boot menu? iamafan's build

Hi all, I built my sdcard per: http://iamafanof.wordpress.com/2012/...r-nook-tablet/ (built by"Succulent")
My kids have two NT's. With two 16GB Sdcards, one class4 the other class 10. I know class4 is recommended, but one poster in forums said he's taken images of CM built on class4's and applied this image to class 10's in several cases and has had no problems. So I thought what the heck, can't hurt to try, so that's what I did (using Winimage). It booted fine 5 or 6 times for me, and I installed several APK's of games from Humble Bundle . I turned over the Nook to my little girl and she brought it back to me later showing she gets errors on boot, after swiping the lock symbol to unlock it. One is "Unfortunately, Talk has stopped". If you click OK on this, you get ""Unfortunately, Trebuchet has stopped". Clicking OK on this does nothing, it keeps popping up indefinitely. I don't know if the sdcard is hot pluggable (can be removed with power to the tablet), but she did admit to doing this. So I'm wondering if some corruption occurred to the CM build on the sdcard. Has anyone seen these errors? I could reflash it from the image I made off the class 4, but want to understand what happened so we don't run into it again. The funny thing is, I don't recall the startup wizard off the 1st class4 card prompting me with several screens regarding Google crap like it did on the 2nd card which was flashed from the same image. That was even after telling it I had no Google acct hoping it would leave me alone.
can anyone explain the boot menu you get when you press the N button? (I'm not including the faded selections) I'm wondering especially about the recovery options. Here's my menu:
INT BOOT ( I assume will boot to B&N native OS?)
INT RECOVERY ?
SDC RECOVERY ?
SDC BOOT (Iassume, boot to CM10 off sdcard?)
SDC ALTBOOT ?
START FASTBOOT ?

Yes,
internal boot - boots Rom in emmc
Internal recovery - recovery in emmc
Sdcard boot - boots your sdcard Rom.
Sdcard recovery - boots sd card recovery ( keep recovery.img in root of sdcard for it to load recovery)
Sdcard altboot - alternate recovery ( not necessary, unless you want both cwm and twrp at same time)
Fastboot - fastboot mode , fastboot commands to flash .img file etc with this method .
As for your problem, try entering recovery, wipe cache and dalvik cache partition (I've done this on emmc version, never tried sdcard version of any Rom) this may solve the issue. If not try factory reset.
And removing sdcard while device is switched on is called hot swapping , hot plug is a CPU governor. Not sure if sdcard roms are hot swappable, but I think not.

Thanks.
emmc=internal nook memory I assume?
Oh, and...just to clarify, I haven't modified (rooted) my tablet. (you mention factory reset). I should mention that with the sdcard out, it boots B&N OS just fine.
And the part you say about wiping the two caches, so I should go into SD Card Recovery to do that? Once you get into it, you have various choices like the ones you mention? (I'd read that this choice was to backup your NT to sdcard). And please, I want to be very, very careful not to wipe out the B&N stock OS, so please, any detailed instructions you can give so I don't make that mistake, I'd greatly appreciate it. (I see so many posts on these forums about people bricking their Nook tablets it worries me.)

Um I don't know much about how it works for sdcard Rom. I've always only used emmc version. I guess if you were to enter recovery, it would access the stock cache partition by default , and we aren't trying to clear that.
Try this - use titanium backup (only talking about your sdcard Rom here, nothing to do with your stock) and in options, you may be able to wipe your cache or dalvik cache.
Or,
boot into your sdcard Rom, in settings > backup and restore > factory reset. This will delete all user data and return Rom to original Cm10 that you flashed on sdcard.
Or if it's only google talk and trebuchet launcher issue, install a new launcher (go launcher, adw etc) , then use titanium backup to uninstall trebuchet and talk.
Sent from my ST27i
From what I see, titanium backup is an android app. If I can't boot to Android (Trebuchet error loops as I said) I don't know how I can install this to do anything? Nor can I install another launcher or go into Settings as the error doesn't let you get any further.
I guess if there was a way to browse files/folders on the sdcard partitions on the sd to manually delete the cache files.....but if they're linux partitions (ext3 or4) you can't do that under windows...

In cwm, enter mounts and backup, then (if) you see /sdcard /cache, mount that and format that ONLY.
Do not format anything else as some options can brick device (Rom, bootdata, factory etc)
Wiping cache is safe (99%)
Again, I have never used sdcard Rom so I don't know what will show up in your recovery. But if you see something like sdcard cache, it can be cleared. If it doesn't specify sdcard, let us assume it refers to stock emmc.

Why backing up now when it's not working? Fix your issue, then make a backup. So the next time there's a problem you can restore to working condition.

Well, backing up, I think, was a good suggestion by Digimax. So I'm glad I did it. and now i know how to do it for future. Just in case anything EVER goes wrong, I'll always have that image now on my pc. Bad thing was, apparently B&N nook OS apparently keeps lots of APKs around after installing them. I had to make my 1st fat32 partition over 2GB for the entire backup to process without running out of space. backup size=1.6gb
I ran into lost chains - convert to cluster msgs trying to delete the folder of the first failed backup, but it never would delete even after a chkdsk, so I formatted the card and put the original image back onto it, adjusted the partitions, and then ran into a new probem.....the Cyanomod spinning logo never stopping spinning so it won't boot up. So I give up. I don't know if it's that it's a class 10 card that all these problems are happening. barring any other suggestions, I guess I'll make sure the other NT we have runs stable for a few weeks and if so I'll order another class 4 like that one has.

I don't know about your bootloop issue, but I don't think it's a sdcard class issue.
Anyhow, now that you have stock backup, aren't you going to consider flashing cm10 internally? Do you actually use stock?
Sent from my ST27i
I'm a little leery of it, at least while it's under warranty. I don't know how reliable recovery is.? Besides, my daughter wasn't thrilled with it being down for several days with me fussing with it and asked if she could have her "B&N boot" back I admit It is a bit of a pain having to pull it out of it's case, lift the flap, pop-in or out the sdcard to switch between them. (& also to have to remember to always turn it off b4 removing/inserting)
I may do it in the future though. Thanks for the help
FWIW, you don't have to actually remove the card to boot into stock. Just reboot, hold "n" to get into Cyaonoboot menu and choos "int boot" or something like that, and it will boot to stock with the sd-card still inserted.
Great, thanks for that tip!

I think many of these symptoms could have been caused by a dying card. It did have a corruption error once, and then it finally completely died. Just for anyone else that runs into these.

FWIW, /cache does not need to be backed up, which should help reduce the backup space requirement.

[Q] No Partitions Showing in Parted - Hardware Problem?

I have a Nook Tablet 16GB. It won't even power on to the "n" logo screen unless there is a CWM SD Boot card installed. I get mount errors once inside CWM.
E:Can't mount / cache/recovery/command/
E:Can't mount / cache/recovery/log/
E:Can't open / cache/recovery/log/
E:Can't mount / cache/recovery/last_log/
E:Can't open / cache/recovery/last_log/
I've tried the Factory Restore (repart.img) and it runs through and tells me the device will shutdown in 5 seconds. (The other times I've used this it sits at a green check mark until I shut it down manually) This doesn't resolve the issue or make any changes at all.
I've tried Adam's Ubuntu method and the device boots to the SD card but sits at a blank screen after a few seconds and does nothing, even when left on over night. This doesn't resolve the issue or make any changes at all either.
I can connect to the device in ADB and the plan was to use parted to fix some partitions using Veronica's methods, but when I run the parted /dev/block/mmcblk0 print command no partitions are found at all on the device. I'm never prompted to fix any partitions either. The only thing it sees in the ext sd card partition. In the past when I've done this it shows 11 partitions with some details. This time it shows nothing. I am unable to find any information anywhere as to what to do next.
It is as though the internal SD Card (memory/hard drive whatever you call it) isn't working or detected by the system any longer.
Does anyone have any recommendations on what to try next? Please help!
I'd suggest burning a CM10.x pre-made SDcard image (e.g., cm_acclaim_10.1_21APR2013_HD_SDC_IMG.7z from Succulent's repo http://iamafanof.wordpress.com/2013/02/18/cm10-1-jellybean-android-4-2-2-for-nook-tablet-0218/) and see if your NT can successfully boot and run a ROM from SDcard. If it does then you can proceed to restoring stock ROM (or flashing CM10) internally on emmc.
Also, refrain from reformatting any partition (other than possibly /cache, /system, /data, if you have good reason to do so and know what you're doing), as you risk making the problem worse -- see http://forum.xda-developers.com/showpost.php?p=37515697&postcount=31.

I made an SDCard using Succelent's repo and was able to boot to the Cyanoboot Bootloader but a few seconds later it just went to a blank screen. I rebooted and could get into recovery by holding the "n" button and selecting that. When I select to boot from SDC it just goes to Bootloader and then goes blank. It never boots into the OS.
I never mess around with partitions and I'm not sure how this thing got this way. I purchased it from eBay as a tablet for my daughter. It did say the device was bricked but that the hardware was okay. I've seen bricked devices in the past and the repart.img (Factory Reset) has always resolved the problem. I have a Nook Tablet that my son has been using so I've become pretty familiar with the basics of rooting, loading CWM, TWRP, Cyanogenmod, etc. But I've never seen it were I get mounting errors inside of CWM and am unable to flash anything. It won't even mount the external SDCard once inside CWM.
Not sure what to do and I hate to give up on this. Any help would be greatly appreciated.
Assuming that SD-based CWM is functional, you should try flashing flash_kernel_acclaim_30MAR2013_HD_SDC.zip under the heading "Flash this if your NT doesn’t boot newer kernel" in the SDC image section of http://iamafanof.wordpress.com/2013/02/18/cm10-1-jellybean-android-4-2-2-for-nook-tablet-0218/.
Also, you should try "wipe /cache" while in SD-based CWM recovery to see if that would take care of the /cache related mounting errors you encountered.
This happened to me last year. There is a post in development section about fixing partition table by So****e. It's the last resort, but worked for me.Also, Adam Outlers Ubuntu method loses your serial number, gone forever. Good luck

Happened to my first nookT not to long ago....It died but the best advice I can give has already been given try not to erase more stuff. Digimax helped me not to long ago. Make sure you format your sdcards correctly and if you can flash a recovery or boot into it you should be able to use one of Succulents cards. Good luck

I tried to download the file you suggested, but the actual file isn't there any longer. When I click on the download link it takes me to GOO to download it, but said file can't be found. I also tried wiping my cache partition again from inside cwm, but no luck. Still getting the mount errors.
I believe the real issue is that my device doesn't see /dev/block/mmcblk0 (or rather is sees it as the external SD card). there is no /dev/block/mmcblk1 either. I thought perhaps the internal and external were swapped, but that doesn't appear to be the case. So since the device can't recognize the internal SD card I don't think I will be able to get anything to flash until I get that resolved first. I'm certain that is why Adam Ubuntu fix and Meg's reprt.img aren't working.
Probably the only way to do that, if it is even possible, is to do it through ADB. Veronica has a thread that shows how to recreate all of the partitions, but when I attempt to do that it doesn't see the internal storage at all so I can't even get started.
I really hate giving up on anything so I will keep trying as long as it takes if I know it is possible to fix this, but I'm not sure what steps to take next to try and get the internal storage recognized.
For all I know it could be a permission issue.
Do you know any commands I can run from ADB Shell to try and get the internal storage recognized?
When I run a list command from ADB shell I get the following:
~ # ls
ls
boot fstab.acclaim sd-ext
bootdata init sdcard
cache init.rc sys
data internal_sd system
datadata proc tmp
default.prop recovery ueventd.acclaim.rc
dev res ueventd.goldfish.rc
emmc rom ueventd.rc
etc root
external_sd sbin
~ #
So it looks like the internal storage is working after all and I can get into some of these directories and files and CAT or TAIL them. Perhaps the MBR is messed up or something?

post root Bricked? Nook HD+ by Trimmer, weird boot behaviour, boots only with SD in

Hi
I'll try to make it brief. Some time ago, my stock Nook slowed down like a mule so I decided to root it, then applied Trimmer to enable trim. Beforehand I'd checked the eMMc with a Brickbug app and it popped up with "sane chip", as I'd read some Nooks had a faulty Samsung eMMc.
It went into a bootloop, and only started showing shredded Nook letters on an abstract background during boot. Then I tried various bootable SD cards to try to flash various stuff, as per available XDA threads, especially - leapinlar's, verygreen's and amaces'. First it would not complete the flashing of a ROM, just froze towards the end, then eventually wouldn't boot up at all.
Here's the weird part. Without an SD card, it doesn't boot up at all.
When I make a bootable SD, it only boots to TWRP 2.6.0.0 (some other versions [amaces] it won't boot to), but doesn't see any zips on the card and won't let me flash anything, even though it previously did, but wouldn't complete the flash.
Whatever else I burn on the card, it either doesn't boot up at all, or boots to whatever it is you can see on the attached printscreens, and won't mount anything. So if I'm guessing right, the eMMc is not borked, as it seems the device boots to some remnants of something that's there, and not on the SD.
Is there a way of fixing that mess? I'd appreciate any ideas.
Best
W.
You can try to flash this flashable_fix_bootdata-ovation.zip which typically should cure corrupted or missing bootdata issues.
Hi, thanks but how? The only thing I tried so far that the Nook boots to is a TWRP 2.6.0.0. bottable card and it won't see the zips on it. So how can I flash the fix bootdata zip?

Have you tried the verygreen's old SD-based CWM recovery?
If you mean the one from that thread:
https://forum.xda-developers.com/showthread.php?t=2600572
I have. The download links for the initial card image don't work. I looked elsewhere - nowhere to be found.
Sorry about the trouble, guys, forgot to update the dns when the server moved. I just updated it, but it'll take some time to propagate. The actual new ip address is now 178.34.187.142 - you can place it into your hosts file if you don't want to wait.
Nook HD+ Bootloop error
OK, I tried the succulentboot.zip from your folder:
https://www.mediafire.com/folder/6a4rivb8kkdfu/Nook HD+):
Now the zips on the sd are accessible, so I tried flashing the flashable_fix_bootdata-ovation and the screen shows the result.
I tried flashing stock recovery too and it says it's done that, but I guess without the fixed bootfiles it won't work anyway.

Assuming that your flashing of stock recovery was successful (recovery's reports of successful completion can sometimes be erroneous) and also your factory backup partition is still intact, you can try to initiate a factory reset by using the "8 failed boots" method: with the Nook in the power-off state, power it on, then as soon as the boot screen appears hold down the power button until it powers off, do this 8 times, and the Nook should go into stock recovery to revert to factory-fresh state.
Flashing your flashable_restore_stock-recovery-ovation zip ends with the screen I'm attaching.
Then I tried "8 failed boots" but it only boots to CWM SD, without the card - it doesn't power up at all.
Eventually, nothing changes.
Tried putting the stock ROM on the card and flashing that, but the partition size is too small, even though its a 16GB card.

If the issue is about the two files, you could mount /bootdata and copy them manually (ADB shell should be functional with any of these recoveries). You'd extract BCB and BootCnt from ZIP, and copy them onto SD card, then do something like:
Code:
mkdir -p /bootdata
mount -t vfat /dev/block/mmcblk0p6 /bootdata
cd /external_sd or /sdcard or /emmc (wherever SD card root is mounted)
cp BCB BootCnt /bootdata/
Or, you could edit the updater-script inside ZIP to remove the device assert line like in the attachment here. By the way, are the updated images here also failing?
Flashing your flashable_fix_bootdata-ovation-no-assert.zip shows "install from sd card complete" but the device still won't power up without the card.
Trying to mount bootdata results in "error mounting bootdata".
There's no adb command line in that sd recovery, just adb sideload. TWRP 2.6 had it but it didn't access the files on the sd.
Then, I'm not sure I'll know how to edit the updater-script inside ZIP to remove the device assert line.
Chances are your EMMC is hosed, in which case you can try running CM entirely off SD card using the succulent special build available at https://iamafanof.wordpress.com/201...-4-4-4-for-bricked-no-emmc-nook-hd-04nov2014/.
