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] P6800 ROM Questions

Recently I hard-bricked my Tab whilst installing a Rom on it (Brick Bug). Now I have a replacement, and it's about time I replaced the HC with something else.
I plan to use the 'Singha ROM ICS P6800DXLP7' ROM and ' Dedraks' GT-P6800' kernel. I'm guessing installation for both is via CWM, but that is how I bricked my tab last time. How can I work around this as to not brick it again? Odin? Which do I install first? Any guidance would really be appreciated!
Thanks

Which cwm you using that cause it to brick?
Share some detail procedure...wipe on stock rom, custom rom, kernel...etc which end with brick?
For now I believe safe atm..
- From stock ICS
- Root with this method: http://forum.xda-developers.com/showthread.php?t=1849235
- Install cwm using Mobile Odin
- Boot to cwm recovery
- Flash custom rom and custom kernel
- Reboot recovery NOT reboot system.
- Full wipe and fix permission
- Reboot system to home screen
That what I always do

Here's what works for me
first, d/l CWM to SD card.
then power down.
reboot into download mode ,PC Odin is my install of choice for the roms...
then power down again after the new rom installs and re-boots
re-boot into recovery and choose install zip from SD and choose CWM (which is a temporary install)
dont wipe anything, just choose to install zip and then choose your new kernel.
After kernel (a safe one) installs, then re-boot system.
Ive never bricked this tab or my GN7000 Note
good luck

correct me if im wrong, but as long as you do not factory reset in stock ics recovery you are okay. Right?

Some Note GT 7000 guys reported that they bricked their phablets by copping large files (being on ICS). If this doesn't affect our P6800s, then you are not wrong.
I had installed LQ2 without wiping anything. But had many Screen Offs and Shut Downs, so I considered to risk the clean install.
Did it with Mobile Odin Pro, but first
Ensured that I already have CWM 6.0.0.1
Flashed Dedraks Kernel.
In Mobile Odin chosen "open file..." and then the particular md5 file,
BUT EXCLUDED:
1. Kernel
2. Recovery
Then I selected "wipe" and "clean", crossed my fingers and everything went OK.
Not quite everything, because I lost root, although I am pretty sure that I did not unselect "everroot'.
It was not a big issue. Installed again "root.zip" via CWM recovery.
Its about a week since then and I have nothing to complain.

...

Thanks for the responses guys.
Does this sound safe?:
Flash LQ2 via PC Odin
Root from universal recovery
Flash CWM 6.0.11 via PC Odin
Flash Dedraks Kernel via CWM
Then root again if needed.
Thanks

[Q] TF101G back to stock rom.

Hi guys,
I've been thinkin about selling my TF101g and buy a new model, but my tablet has custom recovery and Rom, and I would like turn it all stock, and i couldn't find any thread to the Tf101g.
Can somebody help me with a thread that works?

Hi, I'm new to this forum (first post).
I had the same problem - e.g. I wanted to return to stock. I flashed ' PERI 1-click recovery' and the latest version of Revolver custom ROM for the TF101G but I couldn't get 3G to work (unknown Baseband), and PERI wouldn't let me flash the stock ROM - it gave an error 'assert failed' 'Status 7'.
Thought I'd b*****d it thoroughly and couldn't find a thread telling me how to get back to Stock, but trial and error prevailed.
This is what I did (assume you already have ROOT and a custom recovery installed):
1. Download the latest ASUS stock ROM zip from the ASUS site to the PC. Make sure you select the right one for your model (mine's the WW TF101G version)
http://support.asus.com/Download.aspx?SLanguage=en&m=Eee+Pad+Transformer+TF101G&p=20&s=16
2. For some reason ASUS put the stock ROM zip image inside another zip file, so extract it from the downloaded zip file and copy the extracted stock ROM zip (e.g. WW_epad-user-9.2.2.6.zip) to TF101G Internal Storage (not an external SD)
3. The custom recovery you have installed my allow you to flash the stock ROM, in which case just do steps 7 and then 10 onwards. Mine (PERI) gave me an Assert Failed error, in which case ....
4. Download ClockWork Recovery for the Transformer. I used Clockwork_Recovery_5.8.1.8_by_JvS_Corp_V3 from this site and it worked just fine. I don't know which other versions work and which don't:
http://forum.xda-developers.com/showthread.php?t=1577929
5. Copy the downloaded Clockwork_Recovery_5.8.1.8_by_JvS_Corp_V3.zip to TF101G Internal Storage (not external SD)
6. Now boot the TF101G into recovery mode (Power + Volume Down until prompt appears, then Volume Up for recovery)
7. Wipe all caches (including the user data cache)
8. Flash Clockwork_Recovery_5.8.1.8_by_JvS_Corp_V3.zip - you'll see lots of scrolling @@@@@@@s, don't worry that's normal
9. Once the Install is complete, Boot into recovery mode again - you should now be in Clockwork Recovery V5.8.1.8
10. Flash the stock ROM (e.g. WW_epad-user-9.2.2.6.zip). Wait until the install is complete.
11. Reboot normally. You will see a blue status bar which will take a while to complete and then it will reboot itself, you may see a message 'Android is Updating' which will also take a while to complete.
After doing this, you should now have the stock ROM, stock recovery, no ROOT and you will be asked to set up the Tablet for the first time, i.e. back to stock.
P.S. If you don't wipe the User Data cache, you can flash to stock without using your apps / settings / data.
Hope this helps.

i dont understand. If youre going to sell the tf101 why not load it up with custom overclockable kernel, new JB rom, and a custom touch recovery? those are added features compared to a lame stock version of the transformer.

because it doesn't exist a JB ROM with 3G working, and usually, when i'll sell something, i prefer selling with the stock image, it's more guarantee that will work properly, like when leaving the store, so they can root and change roms themselves.

In my post, where I said "P.S. If you don't wipe the User Data cache, you can flash to stock without using your apps / settings / data", I meant "...without losing your apps / settings / data". That way you can carry on using it until you sell it, and then just do a factory reset once you have a buyer.
Good luck.

CWM & CM10/10.1 problem (hung on "The device is unlocked")

Hi,
On my TF300T I flashed the CWM 5.5.0.4 using fastboot and installed CM 9.1 with the CWM - boots & works fine
I want to install CM10 or 10.1 (using the steps I found in the CM Wiki) but the TF300T always stops on "The Device is unlocked".
Now I found a new CWM (6.0.2.3, recovery-jb.img) for using with JB here at xda-developers - finally to install CM10 or 10.1.
But after flashing the recovery-jb.img with fastboot I want to boot into recovery mode, but the TF300T stops on "booting recovery kernel image".
A boot into the previous installed CM9.1 is still possible.
How can I upgrade to CM10 or CM10.1?
Thank you for any help!

What is your bootloader version? Si it fresh enough?

Bootloader...(!)
I was using ww_epad-9.4.3.30-20120604 - so I upgraded to stock ww_epad-user-10.4.2.20 (using CWM 5.5.0.4), after this I flas the recovery-jb.img (6.0.2.3) - now I can boot into CWM 6.0.2.3 recovery and install CM10. :laugh:
Thank you!

Yeap,.. Bloody bootloader
No problem

Sorry for reopening but - I's crazy!
Heres what I've tried (using Bootloader 1.00e (ww_epad-10.4.2.20-20121226 A03):
First flashing cm 6.0.2.3 and install cm10 and also tried the cm10.1 nightly. Installation works without errors, but on reboot the tf300 freeze on "the device is unlocked"
So I try it with twrp (2.4 jb). The installation of cm10 and also cm10.1 failed with the error "assert failed: getprop"
I also cannot mount /data, no matter what I try.
I've wiped data, cache and dalvik cache every time before I try to install one of the ROMs.
At this time I can do nothing with my TF300, only boot to cwm or twrp!
What the heck is wrong?

But U probably haven't format /system, right? It's another mandatory thing to do when switching roms.
If it fails, using fastboot try to flash system with original blob file (get it from archive of latest official release) - it will fix /data problem - been there, done that
U can also try to install official rom from zip... IF it fails, try fastboot method.
Let system boot, reboot into recovery again and do full wipe with /system format and install newest cm10.1

- now I formatted data and system and also wiped all possible parts
- flashing cwm 6.0.2.3 and installing asus stock ROM (ww_epad-user-10.4.2.20), reboot
- cannot access cwm recovery, so I reeflash it with fastboot method
- access cwm recovery and install latest 10.1 nightly, reboot, done.
Thank you so much!

I'm having the same issue.
I bought my TF300T when if first came out. I finally decided to play around with it.
I unlocked it with the Google Play app.
Used fastboot to push the latest ASUS JB4.2 firmware (US_V10.6.1.8)
My bootloader says: (1.00 e) released by "US_epad-10.6.1.8-20130225" A03
I rooted and installed TWRP v2.4.4.0
Everything is working fine for me and I have taken a solid backup, so I'm able to restore back to that when things fail.
I loved using CM7 on my phone, so I wanted to try CM10 on my tablet.
I have tried installing the stable CM 10.0, and I've tried all of the CM 10.1 Nightlies.
Every single time, the install goes perfectly fine, but when I reboot I just get the plain white Asus screen and then it freezes.
I have tried installing with and without installing the gapps.
Every time I install I do a Factory Reset, wipe the Cache, Dalvik Cache, and System. The only thing I didn't do is wipe Data as I'd prefer not to lose my files. (is that the problem, is the data-wipe required?)
Is there something obvious that I'm missing or a step I left out?
Any help would be greatly appreciated.

I tried doing it again with wiping all my data too...that didn't make a difference either. Still freezes on the white asus screen.

Hi, I just registered to reply, as seems noone did. And Ive been there myself, also with the 10.6.1.8 bootloader. Thats the issue. Cyanogenmod isnt compatible yet with the newest bootloader 10.6.1.8.
I hope it will in the future, Im awaiting it too. Until then I just rooted the stock rom, and using it that way. You could try the CROMI-X rom, but its also stock based, I havent tried it yet, maybe ill give the newest update a try (4.3) which will be available in a couple of days, as I really love their newest boot animation(wich I believe isnt included in the 4.2 version)
Till then, no Cyanogenmod for us with the newest bootloader.....also downgrading is not worth the risk if you ask me,,, even if its possible. So Ill wait for the Cyanogenmod team to update their version to ours.
Advice: dont mess with the bootloader nor the recovery img files. Always read carefully if you wanna change recovery if its compatible with your bootloader. If its not, and you flash it...tada....youre the owner of a cool and expensive brick. Dont wipe data in the bootloader, cuz as I understood reading posts here at xda, it will wipe your entire device, including bootloader...then your kinda screwed. So stick to what you have and let the devs do their work to update their roms for the 10.6.1.8 bootloader...MOST importantly, DONT store your device with the keyboard dock closed...(like a laptop)...your screen will crack eventually.I gathered this info on youtube as well as here, and Ive a friend, who was using the device with the dock till last month like that, had it from last august...result, screen cracked 3 weeks ago...its a design flaw in the transformers, the screen is under heavy pressure while in the keydock..I just got my dock last week,, Im storing it separately, and I never close it, only use it for typing, battery and usb.
im writing all this as I think I wont find this post again to reply if you read it.

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!
