Any CM7 based Rom hangs on boot

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

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.

wiped, bricked tf300 now installing c/roms but still booting to twrp?

hello, last week i bricked my tf300, this is what happened...
i installed the energy rom along with the 4.2.1 bootloader, i was already using twrp 2.4.3.0 and it seemed to work fine for a while but then i had problems with a double screen after trying a different rom (cant remember which) anyway i tried the usual resets and wipes to to fix it but no joy. I then used the wipe data in bootloader thinking a full clean wipe would sort it but it just booted straight into twrp.
in twrp nothing will mount apart from system, ive used fastboot to flash various stock blobs, proper twrp img etc but even tho fastboot said everything flashed ok, i still boot into the old twrp which wont mount anything apart from system.
i then got an old 8 gig sd card and put stock roms and energy rom on root of the sd card , in twrp i mounted system but cant mount cache, data or sd card but strangely, i was able to copy the above roms from the sd card and move them to the mounted system partition which i was then able to install the energy rom with aroma installer , happy days i thought until after installation it rebooted straight to twrp again asking for password?
when i try to install stock roms by the above method it fails because cache isnt mounted. i think the twrp is corrupted, how do i fix this?
could someone with the know how tell me what im doing wrong,? should i full wipe again? should i wipe the twrp and how do i do this?
i am sort of a newb to this and any advice would be great

Bootloop CWM ok+no format data+rom bootloop+no pc[SOLVED]

Hello,
First sorry for my English, i´m from Spain and i read-speak only a little.
I've been searching for a solution for my problem but i cannot find it.
On Friday when I had in my hands my TF101 (i just in chrome browser) just restarted, and restarted it again in a loop.
The first thing I did was go to Recovery ( CWM Recovery 3.2.0.1 -r1 Roach2010 ) to run a backup .
I try a cold boot, without results.
Then I try to restore to a previous backup and follows restarting.
Next i try was to install the stockrom I had previously installed, the last StockRom recovery from wipes and did the install , reboot the blue bar goes loading screen asus just restarts and restarts and restarts.
I think that the installation can't be completed because the restart.
Then, I do a wipe data/factory reset and I get an error.
I can not delete a file(/data/data/com.asus.reader/cache/files/media_external_file176Satellite.pdf ) and CWM cancel the formatting /data.
I try to make a format / data and I get the same error.
I´ve tried doing all wipes (data can't) installing all my previous buckups. Everything seems to be installed but reboot continue.
Otherwise I tried to connect to the PC ( 3 to be exact) OS: Vista x64, 7, 7 x64, Linux x64, Linux live cd.
I pressed Pwr + Vol + from 6-60 sg, after shutoff my tablet from CWM, connecting the usb cable before or after and no detects the TF101 .
I ordered a new cable, but mine seems to be good and i can charge the TF101 without problems.
I have read as Xda-topics as I can , I haven't seen in any solution to my problem ( CWM Recovery working + no format data + bootloop + pc no connection).
I´m afraid of brick my tablet. Only lives in recovery, no Android (reboot), no apx, no adb.
What can i do to format /data ?
Can I flash from my actual CWM another Recovery (maintaining the functionality of the microsd ) as TWRP? what happend if failed?
Thanks
PD. I really learn a lot with this problem reading yours posts.
Thanks

1.) Put this flashable zip on your Micro SDCard
http://nexfiles.kjonigsen.net/tf101/twrp/twrp2.6-tf101-unofficial.beta.zip
2.) Flash it from inside CWM Recovery
3.) Reboot tablet into recovery, check that TWRP is the new recovery
4.) Copy this ROM on to MicroSD Card
http://downloads.timduru.org/android/tf101/K.A.T/KatKiss/dev/KatKiss-4.2.2_226.zip
5.) Copy Gapps onto Micro SDCard
http://goo.im/devs/teameos/roms/eos4/gapps/gapps_4.2.2_TF101_20130323b.zip
6.) Boot into TWRP recovery
7.) Wipe SYSTEM, DATA, CACHE, DALVIK CACHE
8.) Flash ROM, Flash Gapps,
9.) Wipe CACHE and DALVIK CACHE one more time
10.) Reboot into working Jellybean ROM
The above will wipe everything clean and install a fresh JellyBean ROM to your tablet

First thank you very much Detection.
My new usb cable should arrive today and i'll try to apx mode recongnition.
In any case I downloading the files you provided me, but i have one question

Here i must to reboot into new recovery from old recovery. Not need reboot tablet to OS (bootloop) ¿ok?
Thanks, thanks, thanks.
Edit:
I do it, i flashed TWRP, reboot and reboot into RCK. ok
Now copying camera data to microsd, and ready for wipes.
Thanks.

Sounds like you are making good progress
No need to reboot into OS, just into new TWRP recovery, then wipe and flash new ROMs etc

Yes, thanks.
I plugged my tf 101 with my new cable and now is detected in windows 7 x64. Naked drivers installed.
But before that, i flash TWRP recovery and it's fantastic. I can copy all my photos to microsd. I need to have this out TF101.
Now i installing the rom and gapps, but seems to be freeze on the four colour circles screen.
More than 20 minutes.
I'm thinking on reflash all an try again.
Thanks Detection.

Make sure you wiped everything before flashing the ROM & Gapps
The animation should not freeze during boot

I do all wipe data, cache, system, dalvik.
flash rom
flash gapps
wipe cache and dalvik
reboot.
and, not freeze but keeps moving and now + 30 minutes.
Something's bad.
I'm thinking on trying apx mode to solve.
Maybe

EDIT - See if it boots without Gapps first (Wipe everything again but only flash ROM)
1.) EDIT - Try this

Use Easyflasher to flash TWRP again, then try wiping and flashing ROM and Gapps again
IF THE ABOVE FAILS DO THIS:
2.) Ok, try this to rebuild the Partitions, this will flash the stock ROM to your tablet, if you have SBK1 (Serial number B6O or before, some B7Os)
http://www.xdafileserver.nl/index.php?dir=Asus%2FAsus+Transformer+%28TF101%29%2FSTOCK+ROMS%2FICS+.27
Choose US or WW
Connect TF to PC > Power Off TF > Put TF into APX mode (Vol Up & Power)
PC will recognise TF but nothing on TF screen will show
Extract the ROM above > Run download.bat as Admin (Right click > Run as Administrator)
Let it flash the ROM, this takes a while, maybe 10+ minutes
If that works, and you can boot, we can use Easyflasher to root and install TWRP again, and then flash Jellybean ROM again

I tried flashing rom and gapps again. No works, keeps on 4 turning circles screen. I leave it all night connected to AC Power. This morning was in the same screen.
I tried flashing rom, wipes, reboot. No works keeps on 4 turning circles screen. After 1 hour i restarted.
I'm going to try easyFlasher metod. I'll update progress.
My tf101 is B80 that's Sbk2. ok? Then, how can i rebuilt the partitions?
Thanks.
UPDATE 1.
easyFlasher WORKED¡¡¡¡¡¡
Now I'm on Stock.
I flash recovery and also WORKED¡¡¡¡¡
Next work:
Fisrt root
Afteri ready to KatKiss.
UPDATE 2.
Flashed superuser.
Reboot
Flash KatKiss 226 and gapps.
Then not reboot. But coldboot done.
¡¡¡SOLVED!!!
Thanks Detection.

Ok, you can't use NVFlash with SBK2, but you can use Easyflasher
Try using Easyflasher I posted here in SBK2 mode and flash TWRP
http://www.putlocker.com/file/42672030BC26BD2F
Then try wiping everything and flashing ROM and Gapps again
If it still won't work, wipe again and try a different ROM

I believe that you have a bootloop... Can you tell us what is your bootloader version or firmware version? What is your TWRP version also? You may need to wipe your system to get it up and running again...

Thx LetMeKnow,
I'm using twrp 2.6.1.0. Bootloader number is 10.6.1.14.10-20130601.
When you tell about a wipe, full wipe with full install of the rom again? I will have to do a backup, data only is enough for apps installed?
thx

Your TWRP and firmware are good... I think that your data partition is corrupted and these are my suggestions..
1. In your TWRP, go to Advance and file manager, copy all your personal stuff to your external SD so you will not loose them when you format your data partition.
2. In your TWRP, do a nandroid backup of system, data, and boot
3. Try this first, Wipe everything except your system and your external SD and reboot...:fingers-crossed: If your device is up and running then it is telling you that you have a data partition corruption.. So your data backup from TWRP is useless..
4. If step 3 did not work, then your system is corrupted..You may want to do these.
--Format your data partition
--Wipe everything except your external SD
--Reinstall Cromi x and reboot so you a totally clean installion...
--Now you can restore your data backup and hope that it is not corrupted
--Good luck ....:fingers-crossed:

It's not a bootloop if he's stuck on the boot animation. If it keeps booting back - then yes, but getting stuck on the boot animation has happened to me numerous times (and always when I was on a Hund's kernel - sorry LMK, but Hund's just doesn't work on my tab), which a simple Factory Reset (the default option in the TWRP "Wipe" menu) took care of.
If that doesn't work, then yes - you will have to format data.

The only way to diagnose the cause of "stuck at boot animation" (i.e. to gain insight instead of trying random things involving data loss) is to read the logcat.

Hello guys
Thx for all these infos. Finallly, it was the data...
Just before your answers, I've tried a wipe of cache and dalwik cache. Android's apps updated, and stuck again on logo animation.
So I've tried to update to 5.2a, with no format of data, the same arrived.
I've reinstalled the 5.2a with full wipe, and now it's ok (I will have to do it again, some options unselected are finally necessary. I will go back on 5.1.2 one if no update of 5.2a in the week.)
How can the data be corrupted? I remember, I've had installed an apk from googleplay, this apk can be faulty?
Thx

I seem to be having the same issue with the same version of CROMI and TWRP 2.4.4.0 so I wiped the tablet and put the ROM on a microsd to reflash. For some reason, I'm not seeing the zip file in the file manager or the install option. Please help.

TF700 with Chrimi-x 5.2a
Hi Guys,
First post. I installed Chromi x 5.2a to my TF700 and it was working great.
I was looking at the options and it said I was using the 4.1 JB theme but I could switch to 4.2 Theme of JB. I did, and when my tablet restarted, I get a black screen and a bunch of errors once in a while.
Is there a way I can change it back to 4.1? I can't access the OS only TWRP.
Thanks!

Weird. I would re-flash the rom. It installs to the 4.1 launcher by default - but something is off... That shouldn't have happened.
Did you clean install CROMi-X?
