Hello
So i decided that i was going to upgrade my bootloader from 4.1 to 4.2 so i could keep installing CM10.1 nightlies. I downloaded all the necessary files (Stock Asus, twrp2.5-42 and CM10.1 nightly), put them on my SD and rebooted into the bootloader. Here's where i think i screwed things up. While in the bootloader i accidently selected the Wipe Data option. It did completed teh wipe and booted into a fresh Andriod install. So i rebooted back into the bootloader and went into twrp and flashed the stock Asus update. After rebooting into hung (after 30 minutes) at the Asus screen with the spinning circle. I rebooted holding the power button and tried letting it load again and after another 30 min still "loading"
i can still get into the bootloader and twrp (fastbooted that back on) but i can't flash any ROM's successfully
My question is did i screw up the partition table or file system since i have read that this can happen. If so how can i verify this and can i fix it? IS there anyway to recover my tablet or am i going to have to pay Asus to fix it?
Thanks
No, no brick you have to flash stock Asus firmware blob via fastboot then flash latest twrp then flash Asus firmware in twrp

Why do you think it's screwed?
BTW if you used the correct version of twrp (-jb for 4.1 -4.2 for 4.2) it should have wiped them correctly!

Because it says tmpfs...which i think means temp file system
also i didn't do the wipe in twrp i did it in the bootloader
Yes, the bootloader contacts the recovery and the recovery peforms the wipe! If you have an older version of twrp: it doesn't know the partitions so it wipes Them wrong!

already rooted. is there a step by step to downgrade to ics. really miss my flash player. can't get it to work on jb.
There is not a way to downgrade at the moment if you are running the OTA JB.
Btw flash can still work with JB using the stock browser. Here's a copy of the recent flash player if you need it

I would think to truly do this, you would need to flash the bootloader, system, and recovery all at the same time so everything is in sync with ICS, just not worth it.

Well, can't we just download the latest ICS factory image from Asus? Or would the bootloader prevent us from even using the factory ICS image?

When I was locked, I tried to take the zip and put it in internal storage. It installed the downgrade as it called it, but when done, I was still on jb. I would think if you're on jb and force flashed the ICS blob it would possibly brick the device because jb has different permissions and from what I've read a different partition table all together.

I don't believe it has a different partition table but even if it did, asus blobs include the partition table in every update so that wouldn't be an issue, the issue however is that you cannot download the bootloader, the bootloader is now signed seperately to the rest of the update to prevent abuse like what we did with the tf201 to obtain nvflash access. When you unlock the bootloader signature remains enabled while the blob flashing signature check is disabled. This has a side effect of preventing downgrades as the bootloaders pre-JB do not have this same signing mechanism in place.

I actually attempted to downgrade last night. Quite frankly, I think that I came close o a few soft bricks. I tried flashing a custom ICS rom...no go. I tried loading the firmware from the Asus website to the root of the SD card and restart...no go. I tried force flashing the firmware using recovery mode, and it completed "successfully." When I rebooted...no go...and no ROM. This is when I started getting worried, because when I tried to boot into recovery, I received a red error message saying that there was a mismatch. I hard rebooted again, and booted into recovery, and reflashed my JB Rom. I did everything BUT use fastboot to load an ICS recovery image. I didn't want to take that risk.
My suggestion....leave it alone. I am leaving it to the experts. And if you are not an expert, then LEAVE IT TO THEM TOO!

Good suggestion haha - now I have been reading about nvflash being usable for the tf300, but only if you were on the ICS bootloader, wondering if you can do an nvflash type backup - don't know much about it - but after backup, upgrade to jb, then use backup to return to ICS...

I tried every method out there to get back to ICS. So there is no way. Tried fastboot, tried adb, tried wolfs downgrade method, tried restoring a backup with CWM and TWRP and many more. So unfortunately there is no way, but Scotts and Seanz Roms were the best Roms on ICS, so I think I dont have to, cause I have the best Roms to choose.
Only thing missing is NVflash and OC (its been working on )
Have you tried erasing everything

I recently just restored my bricked Tf300 by using these commands from fastboot thanks to user Buster99
fastboot erase system
fastboot erase recovery
fastboot erase userdata
fastboot erase boot
fastboot erase misc
fastboot erase cache
fastboot -i 0x0B05 flash system c:\adt-bundle\platform-tools\blob (this is my path - your's may vary depending where you stored your blob)
fastboot -i 0x0B05 reboot
this completely erased my system, fixed my bootloo and brought it back to stock. Can there be a way to erase the bootloader this way???
Link to how i recovered "http://forum.xda-developers.com/showthread.php?p=45386598#post45386598"
Managed to brick up my tablet good, thought i'd describe the "symptoms" and what I was doing when it happened to prevent it happening again.
I was on:
Firmware: 10.4.4.16
Recovery: TWRP 2.2.2.0
Description:
I was attempting to get root, however TWRP does not work with the new firmware/bootloader version. I wanted to do a factory reset of my data, but TWRP would not let me. I booted into the bootloader menu (voldown + on) and selected data-wipe option. The tablet then rebooted into TWRP but nothing happened.
I have tried to reboot after this but it will not load Android, it just loops into TWRP recovery
I have tried to boot into fastboot, but It will not even load the bootloader menu, it just loops into TWRP recovery
I have tried to flash stock firmware using TWRP but it does not work because i'm running the crappy new firmware!
Anyone got any ideas? I think this one is for Asus :/
are you trying to flash ics or jb?
i would stick with jb at this point.
do you have any backups? one guy said he was able to restore cm10 with twrp.
and if you don't have a backup you can restore, you can always wait for the next version of twrp to be released and try flashing that first. you still have options!
did you activate NVFLASH? please tell me you did!
you can always jump back to the .26 stock bootloader (or TWRP/CWM if you had one of those installed at the time)
there is an unofficial 6.0.1.4 version of CWM Recovery posted and I used that no problem with Official JB to re-root after the update.
you do need fastboot access to install it though, so without NVFLASH and the ability to downgrade your bootloader... um... yeah, you're kinda borked. sorry.
No backups.. :/

Boot into fastboot and try flashing the unofficial cwm recovery! If you have recovery, you should absolutely have fastboot. I would really recommend that you try to stay away from the official recovery since it isn't quite as "feature rich" as cwm/twrp... Good luck,have fun!

Edit. Woah, reading failure... are you completely sure you're doing it right? The new jb boot loader menu is different. You don't wait for a secondary menu, you just vol-down to select the USB icon then vol-up
Make that two. Same as you, tried to get root, wiped data, BRICK. Get TWRP each time, every time unless I hold VOL UP which of course goes to APX mode.
No fastboot, can't flash ROMs, tried the whole "dd if=/sdcard/blob /dev/block/mmcblk0p4" thing and it reboots the tablet automatically. Flashing a ROM gives "E:cannot mount /data".
"ls /dev/block" command from adb shell only shows /dev/block/mmcblk0p3 and /dev/block/loop0-9.
Bricked and bricked good!
Bugger. I'll give it a week then rma, I've still got adb through twrp..

ok do this, boot into TWRP, adb push my CWM recovery, dd if=cwm-recovery.img of=/dev/block/mmcblk0p9, it should flash the CWM Recovery, or you can do it using via fastboot as well. Then flash the .30 zip, remember now .26, but only .30, wipe data, wipe cache, reboot

DId the dd command complete correctly?
Also try this:
1) download .30 blob from asus website
2) unzip it twice till you have a blob file
3) adb it to device
4) dd if=blob of=/dev/block/mmcblk0p4
5) reboot and wait for the flash to complete.

Yes it completed.
The blob reboots the tablet 5 seconds after the dd command is entered.

I could provide you a flashable zip with the stock recovery, send me a PM if you are interested.
I've been having similar issues after installing JB woith recovery. I wanted to wipe data but glad I wasn't able to after reading this thread. I don't understand how some people have managed to upgrade and still seem to have full access to twrp
My understanding is that TWRP is *not* compatible with Jelly Bean! It may install, but it doesn't work right. Stay away....
I have been unable to get the "unofficial" CWM recovery installed at all - everything looks like it works during the install, but I still get the stock recovery. Strange...

Sure I'd give that a go. If anyone wants to go through the trouble of a clean install TWRP backup I'll try that too.
Hi,
I was wondering if you just flashed with fastboot the blob file as I am gettin an error and cannot upgrade to JB.
Is this the only way for it though?

Best and thank you very much (using WW version),

P.S.: As CM10 is switched to JB bootloader, I and a lot of others need to upgrade...
look here
I was using CM10 on the ICS bootloader. I downloaded the most recent JB update from Asus to my pc and unzipped once. I copied that zip to my internal memory. Booted into recovery. Using TWRP, I wiped cache, dalvik, system, factory reset. Then installed the Asus zip. Voila, updated to the JB bootloader. I then downloaded twrp 2.3.1 for JB bootloader to my pc and put it with my adb/fastbbot files. Rebooted into fastboot and installed TWRP. Rebooted into recovery, made a backup and installed CM10 10/31/12 nightly for JB.

Maybe I am too stupud but
I have a TF300TG
I ejected my micro sd card so format should not matter.
I still get Error7.
If I edit updater-script it just failes instantly.
I am using TWRP ICS recovery for TF300T but this should not matter as well??
Can someone with a TF300TG can give me a hint how to update?

Hello.
A was installed a recovery on my tablet ( CWM ) and rooted.
Then i wipe all ( data/factory reset, cache, dalvik cache ) and the i was install cm10.1
Now my tablet are stuck on asus logo and i cannot do anything.
My firmware is 10.4.2.18 ( i was updated then a was rooted my tablet )
What can i do?
Sorry my english.
Thank you.
Please someone.
Nobody?
My tablet is on from yesterday because if i turn off she turn on

READ COMPLETELY BEFORE ATTEMPTING!
While the tablet is on, hold power down until it turns off. As soon as it turns off press volume down while still holding the power button. That will enable you to choose to go back into your recovery or fastboot. Recovery will be the icon labeled RCK and fast boot will be the USB icon.
You could also choose to just enter RCK (recovery) and try to do a factory reset, try to flash the ROM again or flash another ROM from your SD card.
If you are positive you have choosen and flashed the correct ROM the first time, did you remember to do a factory reset, clear cache and dalvik before flashing the ROM? That could very well be the reason you are in a boot loop.
If you are using CWM as your recovery and cannot use it to flash a new ROM from your SD card, you may need to flash TWRP using fast boot in order to flash a different ROM from your SD card.
There is a TWRP thread in the development section. Download the TWRP recovery blob and flash it using fast boot.
You also have another option. You can choose to flash back to stock using fastboot. Here is a great tutorial that will guide you step by step on how to do it. If you are unsure of what to do and want a quick fix, use this. Make sure to thank him for the great tutorial after you finish if you decide to go this route.

Hello.
Yes, i was sellected factory reset first ( wipe data / factory reset ).
I have jellybro and cm10.1 on my sdcard. I wipped all more times and try to install roms, but the result was same.
In this case, shoud it by solve it in the same way?
Sent from my LG-P500 using xda app-developers app
I had this problem with mine when I was flashing it, but I was still on the ICS firmware when I tried to flash CM10, that's what caused the problem since the boot partition gets resized in the stock JB update.
Are you sure you were on a 4.1 OTA stock update before you tried this? Have you tried wiping data/system/cache and re-flashing the ROM again?
I ran a backup of my stock rom before flashing CM10, so when it wouldn't boot after the initial flash, I restored, and it was then stuck at the ASUS screen saying 'unlocked device' what I had to do to mine was extract boot.blob from cm9.1, boot the tablet into fastboot, and then run fastboot -i 0x0B05 flash boot boot.blob that got me booted back into a live tablet. I then took the JB OTA, and started over, flashing recovery, root, doing another backup, and then wiping and flashing CM10, which worked perfectly.
HOWEVER. If you're 100% certain you were on JB already, this may not be the case.
Yes. I was on jb 4.1.1, kernel 3.1 ( i,m not sure, but this i remember ) and, for sure, firmware 10.4.2.18
Sent from my LG-P500 using xda app-developers app
I would use the link I posted above. It will at least get you back to stock. It's a very easy tutorial to follow. Once you get the tablet where it will boot, then you can decide on another ROM.

Yeah, dont interrupt the installer. It installs some other important stuff after the boot.img.
And yes, it takes a long time. If nothing has happened after 15min or so, then it might be something wrong.
For me, the boot.img part seems to take between 5 and 10min, depending on the weather outside, the alignment of the stars etc
