Any CM7 based Rom hangs on boot - G Tablet General

Im having trouble flashing any 2.3 based Rom. VeganTab worked fine and so far Ive tried Corwin's and Kornyone's roms and just hang at the viewsonic boot screen. Im new to the GTAB but not android so I'm quite familiar with CWR and flashing Roms. Follewed directions to the T and have yet to successfully boot using a 2.3 Rom.
Any ideas? Not using SD card, only internal if that matters. Thanks in advance.

I know i had a heck of a time getting my first Ginger to flash, but after the first it was easy to jump between them. Only way i got it to work was in CM to mount and format \system and \cache before flashing the rom. Then after the rom was flashed, wipe data, cache and davlik.
Best of luck

I tried that numerous times. I tried mounting, formating, then unmounting. Tried it with a reboot in between the format and install and without the reboot. Still no dice, thanks for the response.

Maybe there is something I'm missing. Here are my steps. This starts out running Vegan 5.11 with no issues. So I am nandroided, partitioned at 2048/0, and have no issues with this Rom. Bekit .8 CWR.
1. mount system
2. mount data
3. Format both
4. Format dalvic
5. Install Rom (Tried different CM7 among others)
6. Factory Reset
7. Wipe Cache
8. Reboot
9. Hangs on white viewsonic screen
I also tried wiping again after a reboot into CWR. Still hanging up. Restore Nandroid and back to Vegan. Also tried mounting and wiping boot with no luck prior to install.

You need to nvflash your tab. Your partitions are wrong. After nvflash you will have no problems installing GB roms

[Q] G-Tab Problems at startup....

Ok, a pinch of history. I have had many Hardware problems and I am now on my 4th G-Tablet. Finally got a NEW one as a replacement. I got it home today and loaded it up. Let it update and the latest build still stinks.
So I installed cwMod .8 and then CM7.0.3 stable. It then started to hang at the "Viewsonic" Screen. I realized that I likely had the boot loader problem since I was installing over a newer version of stock.
I wiped back to stock with nvFlash and allowed it to update to 3588 since my understanding is that this is the transition point I need to be at. I reinstalled CWMod .8 and then loaded CM7.0.3 again but it hangs at the startup screen with the spinning circle.
So I tried installing Vegan 7.0.0 RC1 and this also hangs at the pshycodelic "Vegan-Tab" startup screen. Any thoughts about what is going wrong?
have you tried repartioning 2048/0?
It shouldn't be a bootloader issue, as 3588 is a 1.1 bootloader, as is CWM .8 and CM7. It's probably an easy fix (I hope) try repartioning, wiping data, etc...
i think it's not in the hardware problem.. try repartitioning sd card select 2048 then 0, then reboot..
for clean install, use nvflash + calkulin's format all, then partition sdcard for assuring.. cause i dont know if calkulin's format all does partition..
then install your desired rom + wipe data + wipe cache + devilk cache wipe(advance setting cwm)
I just posted about an issue like this and I had a ton of trouble with it the format or wipe data did not work but repartitioning the sd card worked like a charm thanks alot.

boot recovery image boot loop

okay 1.2 branch of Gtablet loaded cwm v3028 and cm7.1 Rc no problems also did the partition and permissions. Then I decided to push it and loaded vegan 7.0 over the top of CM7.1 RC. So I went back into cwm and cleared all the flash and loaded the rom.
now im stuck in a loop where it boots and goes directly into the recovery mode. the recovery mode has all the commands. So here are the things I have tried.
1. wipe data/factory reset
2.wipe cache partition
3. I have repartitioned sd card and wipe dalvik cache
So any ideas?
I have searched the forum but didnt find any answer
Thanks
well from my experience, when this happens i have nvflash back to stock.. if you go to install zip from the SDcard and there are no directories it didnt flash properly... NVflash back to stock then flash the rom... that always worked for me...
same
I have the same prob. Any solutions?

CM9 boot animation loop

I have clockworkmod recovery installed and rooted. It's been a few months since I rooted, and can't remember exactly what I did, but OTA updates stopped working. Hence, I am still on gingerbread.
Trying to flash a custom rom now, CM9. I tried the rom manager method several times, found out that wasn't recommended, and then tried the recovery method.
The same thing happens either way: it boots into CM9, but the boot animation keeps playing.
With the rom manager method, I tried wiping nothing, then tried wiping dalvik only, then tried... whatever the other option was, wipe cache and data?
With CMW recovery I downloaded CM9 zip and the appropriate GAPPS, moved onto the internal SD card, booted into recovery mode Wipe data/factory reset, then Wipe cache partition, then install both.
I'm able to restore from backup each time, but this is annoying.
Thank you
1. Install ICS Radio (UCLF6)
2. Wipe Data/Factory Reset
3. Format /System
4. Install CM9.zip
5. Install Gapps.zip
6. Wipe Cache/Dalvik
7. Reboot
:good:

So "UCLF6" appears to be rom that is similar to stock, I'm guessing the idea here is that I'm resetting the phone but retaining root, the idea being that something on my phone is messed up and preventing CM9 from booting but doesn't prevent the current rom from booting?
Two other questions
1. Won't format/system wipe out all my backups in addition to my data?
2. Have you had or seen this problem before? I'm hesitant to commit myself to something, especially with no backups, if it's just a theoretical fix. I do appreciate it either way.
UCLF6 is an ICS modem/radio you need if you're coming from gb.
If you back up though CWM you can restore again later if you want.
Formatting /system will delete the operating system.
Formatting /data will delete your apps/settings/wallpaper etc...

I had a similar boot animation loop when I went from stock GB to stock ICS. What seemed to fix it was updating my CWM from 5.0.2.6 (non-touch) to 5.5.0.4 (touch). (BTW, I couldn't find an advantage of stock ICS over stock GB. I have since put on CM9 which I'm liking).

Still got the boot loop.
When I did the "Wipe data/factory reset" I did get an error message during one of the processes"
"Error mounting sdcard/.android_secure!
Skipping format"
I had a boot loop problem when I first tried to flash JB. I went from GB to ICS with a custom rom a few months back, but I couldn't get any of the new JB roms to work. I ended up having to upgrade my CWM to the touch version in order to get JB flash to work. Also, a tip-- the boot animation will take a minute or two even when it is working. Don't assume it is still a problem if you see it more than once.

[Q] Problem booting custom image [A510]

Hi, this is the first android device I have played with so naturally I managed to mess it up.
The problem is with an Iconia A510, wrong forum but didnt find a Q&A for A510 so I tried here instead.
I rooted and installed CWM recovery. The custom firmware I have tried or stopped during boot and rebooted the device. Booted for 10-20 seconds, I see the animated logos before it reboots.
I upgrade with:
wipe data/factory reset
wipe cache
advanced -> format /system
advanced -> format /data
advanced -> format /cache
install zip from sdcard -> external sdcard
Am I doing something wrong with the upgrade? Can I upgrade CWM from inside CWM so I can try the latest Android version? Is there a firmware version that will work?
Info:
Files from: acer shreps fr
CWM version: CWM Recovery v6.0.1.9 by NoThrills for A510 tablets. Apparently can try KitKat with it, so only tried older Android.
All installed OK but stopped during boot:
7comp-JB-a510-Nightly-20130808

did you try to wipe data or/and dalvik cache after you installed the rom? (DONT WIPE SYSTEM!)
sometimes this will work for me.

Thanks for the tip. I tried wiping the usual suspects, flashing a CM rom and then flash data and dalvik cache. Same thing; started booting, the CM logo comes up and starts spinning before it freezes and reboots.
I'll play around a bit more. Tried the 'fix permissions' in CWM recovery, no go.
Solved it. Formatted everything except external_sdcard, flashed with AOKP and booted fine. Magic!

[Q] Trouble flashing Cromi-x JB 4.2.1

Ok, i'm trying to install Cromi x JB 4.2.1 by flashing it from my SD card
I'm on bootloader 10.6.1.14.0
TWRP 2.6.1.0.
I flash the zip from the sd card like i've done many times with other ROMS. Everything looks fine. I go through the install steps for Cromi-x, everything appears to install correctly. I get a friendly message telling me that everything went great, to reboot my tablet, and to enjoy!
But TWRP tells me that no OS is installed. When I reboot, it goes to the ASUS splash screen and just sits.
What could I be doing wrong?

Did you mean 10.6.1.14.10? It happens to me once in a while with that issue... If you don't have anything to save and I guess that you don't. First, you could try to wipe your system, cache, and data from your twrp. Then go to mount button and manually mount your system, cache, and data then try to install your ROM again..:fingers-crossed: If it still doesn't mount your system, you have to go through the steps above with a complete shut down of your device and don't install anything if ask.. Then boot back into your twrp and manually mount all your partitions then install your ROM. Good luck...:fingers-crossed:
That usually happens when /system can't be mounted correctly or the installer didn't actually finish (even though it reported it did).
Try rebooting and wipe /system and flash again as said.
