The tab don't work.. i see the bootlogo ... The cmw work, so i tried to restore to jb hydro... but it doesn't work... Now how can i resolve?

hi !
In the recovery mod, try to wipe dalvik, cache and data after that flash your rom again...
if you can try CWM or TWRP recovery ...

I'm having the same Problem
Today i went to CyanogenMOD site and downloaded the most resent Nightly build of Cm10, flashed it into my TF300T and now im stuck in Boot Loop. I used CWM to make a full rom backup before than, but when i do restore from backup everythign goes well, until i reboot it, then it hangs in boot loop again. What can i do? (I followed more than 3 tutorials step by step so i dont know what went wrong. It was OTA JB 4.1.1 , then i unlocked bootloader and rooted, then i did stock rom backup with cwm and then i flashed cm10 nightly and issues started. =(

There is no way of flashing Cyanogen JBs if you are on stock JB. Only Rom available for you is Hydro JB. All otheres are not flashable until the Cyanao Crew get the new Kernel and bootloader to run.

Did you do a full-wipe (wipe data, cache, dalvik-cache, and system) if you did, try TWRP recovery 2.2.2.0 it might say it wiped, but it might be leaving some data behind or you can try a double wipe. I usually wipe front to back, but some people wipe back to front.

The only reason i tried CM10 was to overclock using ezoverclock (if thats possible) because it failed to OC on Stock JB due kernel changes.
Can I overclock using ezoverclock on Hydro JB?
Why didn't my Stock rom backup work either?

Ok then, im going to download stock JB from Asus site , and after it boot ur and start running smooth im goign to restore backup, and hope it all return normal, thanks for the help, i let ya'all know if it worked.
Edit: I downloaded stock firmware from Asus site and extracted the blob file, moved blob file to c:\Fastboot, then put tablet in fastboot mode via recovery, and flashed blob following this instructions to make it work again.
"U could reflash your unit with stock ROM using fastboot. I just unbricked my unit doing that after 5 days of fighting.
This is what I did, I downloaded job update from Asus then moved the blob to c/fast boot, loaded unit to fast boot then typed
fastboot -i 0x0B05 flash system blob
But make sure our boot loader is 10.4 or it will signature mismatch, so down load the appropriate boot loader .
That's what I did at least and my unit is working again. "
So i'm happy again, thanks for support xda-developers !!! (the instructions in the quote are also from xda-developers)

[Q] ROM Problem : Stuck on boot logo

This is the story
I first installed Unlocked bootloader from asus, CWM recovery for tf300t, and then i used the update.zip to gain root access
I downloaded the CM nightly build, used CWM to backup, then flashed the CM ROM.
It was stuck on CM boot logo for about 30 min, so i restarted and cleared my cache.
I tried flashing again, and it was still stuck on boot.
I then restored to my backup, and now it is stuck on the original ASUS boot animation.
What do I do?

restore with cwm,ifyou can, to earlier version,working
then remove ClockWorkMod Recovery, by fastbooting TWRP instead...much more reliable (team win recovery)
then to root, theres a theres a batch script tool, that,when tablet is connected to pc, will run and reboot the tablet several times, rooting it.
ill look for the link, its in the forums here, debug,defug..something
there are other methods,that worked the best for me...
CM had been having issues, install CleanROM 2.1 HAS THE JB UPDATE V13 in it. its smooth

I have tried recovering with CWM, and restoring to factory settings.
Both didn't work.

I am having the same issue installing any ASOP roms on my tf300t.
I have the TWRP recovery, gained root by flashing.
I can install ASUS based roms like CleanROM fine, but I cannot flash any ASOP roms like CM10.
Just curious on what is preventing us from doing this. Especially when our devices are supposedly "unlocked" with custom recoveries and root.
If this device still continues to be this locked up, I might just have to sell mine when the GN2 comes out.

First declare your bootloader. Have you ever been on a jb-rom, stock or otherwise?
Looking at git for cm it appears the kernel is 2.6, so I would expect that is not a jb rom.
cwm has some issues on this unit.
get into cwm and use fastboot to flash twrp for the proper bootloader you have.
or get into fastboot by use of power and volume down
at that point you can twrp a rom into place; probably not to restore your backup as twrp and cwm have issues reading each others backups.
Good Luck!
Note: If you can power up and access recovery (cwm in your case) you are not bricked and should be able to recover. I have as well as many others. Take your time and go a step at a time! Make back ups and make sure you have fastboot and adb access to your unit! If you are still ics bootloader consider nvflash once you have this mess sorted.

This is a known problem... once u get the OTA asus jb update, u can no longer flash any aokp or cyanogen jb roms. This is due to the kernel in these roms which are based on ics but since uve installed new ota jb bootloader it will not work and get stuck on boot screen. Restore in recovery will not work either. U need to download latest asus firmware and flash it then fastboot a recovery (i recommend twrp) and reroot.

Ah, ok. I have the JB OTA update so i have the latest bootloader :/
I restored my nandroid of stock and it worked fine.
Just flashed CleanROM which is running great. Cant wait till the CM team gets the JB bootloader worked out as i have always loved being ASOP. Any info on when it might happen?

[Q] Stuck on Asus screen after flashing new rom

I bought my Asus tf300t and upgraded to Jelly bean last night. I was able to install TWRP and CWM sucessfully and was able to root using Superuser-3.2-RC3-arm-signed.zip but everytime I try to flash a room it gets stuck on the AsUS screen with top left saying "the device is unlocked" and doesn't move past that point and I have to restore from my backup. I've tried using the CM10 nightly rom and the Hydro rom with the same issues.Am I missing something?

This is probably not the case, but better just double check... You are not trying to flash ICS based ROM on JB boot loader ?
Or perhaps you have not properly wiped all cache/dalvik/data etc before attempting to flash new ROM ?

All the rom's that I've tried were all JB based roms.
Using TWRP i went to wipe - dalvik/cache and then did a factory reset and then tried installing the rom. I think at one point I tried doing a system wipe as well but still no luck

Did you get an answer?

I am having exactly this problem with mine. Did you ever get an answer to the problem?

Which custom recovery have you installed? Version?

[Q] xt926 CM10.2 Stuck on Boot Logo After 1st Reboot

xt926 with unlocked bootloader and can run 10.1 nightly from get.cm with no problem. However, when I install a 10.2 nightly - whether from get.cm, epinter, dhacker or skrilaz - even though the initial boot comes up clean, rebooting after the initial boot gets stuck on the boot logo.
I have tried different recovery images - cwm, twrp, oudhs - and different versions of each.
I have tried clean installs, full formats and dirty upgrades from 10.1.
I have tried multiple force boots from this state (power+vol up).
I have tried with and without the updated gapps and UPDATE-SuperSU-v1.51.zip.
Restoring from backup does not get past this hang. The only way out is to revert to stock (I use mattlegroff's DROID_RAZR_HD_Utility_1.21).
Does anyone have any idea how I might get past this or even get a log?

Only thing that fixed this for me was to flash back to stock 4.1.2, flash newest CWM touch recovery, then flash newest nightly, Gapps, and SU. Then, a popup comes up saying something about the ROM wants to flash your boot image, and asks if you'd like to fix this. I answered YES (fix) and been working since.

Any chance you could link where you got your recovery and SU?
Much appreciated.

Same issue here...
I've also tried everything listed above. I've done everything i can possibly think of to get cm 10.2 on my xt926. For some reason my phone just isn't making it after the first reboot. I've searched and found similar issues but none of the troubleshooting has been working for me. I hope to find a way around this. I need that 10.2!

Same issue here. Not just CM, every 4.3 based ROM I've tried has either failed to boot or failed to boot more than once (more often than not, they won't boot at all).
I've been at this for hours, but I've had no success so far. I'll let you know if I come up with anything.
EDIT:
Here's my setup:
After every try, I flash back to stock 4.1.2 with VZW_XT926_4.1.2_9.8.1Q_62_VQW_MR-2_VQW_CFC.xml. I've edited it so it doesn't flash the stock recovery and so it flashes a modified logo that doesn't show the bootloader warning. Partway through, I booted up and updated to the latest OTA, so I had to comment out the tz.mdm files as well. I was using TWRP 2.2.2.1, but I updated to 2.6.0.0 earlier.

one of 2 things should fix this problem,
use cwm 6.0.3.5 from here or
go to recovery/mounts and storage and format the data-media line (i know it says sd card but its internal, do not format the external ed card line or you will loose data on it)
also i updated matts utiliity to the latest ota, so you dont have to take the ota just to get the baseband. its in the dev forum. i will be updating it to a newer version if you wait until later, with the newest recoveries.
edit, btw 2.6.0.0 is not the latest twrp although i recommend using cwm as some have had issues with twrp including me.

First off, the latest TWRP seems to have fixed the problems (for me, anyway). Second, you'll need to use the most up-to-date GAPPs when you flash. Also, a lot of people have noted that mounting sytem prior to doing their wipes has solved the reboot issues.

Thanks a ton for the help. Flashed latest CWM and bumped up to 4.4 and everything's working fine. I appreciate the help!

TWRP Recovery

Hello, I am having some problems installing a working recovery, here is my story... So first the device was 10.6.1.27.5 and its unrootable, so i downgraded to 10.6.1.15.3, where I installed TWRP recovery, and flashed CM 10.2 ROM, but it was too glitchy, so i wiped all data, and fastbooted 10.6.1.15.3 build and stock ROM. So I am now stock,
I am rooted using MottoChop method, and I cant install a custom recovery... I tryed to install TWRP 2.5.0.0 thats the version I was on before, and also tied 2.6.3.0, when flashing the .blob My device turns unresponsive, even when rebooting it with fastboot.
So left with no choice i tried flashing the .img one for JB, (Note: It is currently NOT a OTA update, but manual, so i used the 4.2 first)
I was Able to Flash the custom recovery 2.6.3.0 JB.img and it booted up and worked fine, but then it couldnt mount anything,
I was getting error message:
E: Cant mount /data
and so on... I then tried to flash 2.5.0.0 and got the same result.
GooManager cant find a recovery script for this device...I flashed the TF300T, since thats the kind i have not TF300TG
Im really lost now... I tried ClockworkManager to find a recovery and it said the same thing, I dont want to flash a CWM with flashboot since i here It is terrible.
Any Help Is greatly Appreciated

I notice that alot of these problems, I end up fixing myself... I fixed the issue
But If anyone ever comes into the same situation, heres the fix...
UPDATE to 10.6.27.5 (Yes newest version) Im using US...
Install openrecovery-twrp-2.5.0.0-tf300t-4.2.blob IMPORTANT dont flash the JB version because its only for OTA updates
Open recovery and TWRP will prompt you to install, and beleive it or not, but apparently you can root the newest version,
Just not With MottoChopper and other quick root methods!
If you have any more question, post!
