lol, im sorry, ill start over.
a year ago, when i bought it, i unlocked it, put the cwm recovery and burned "baked" rom which is based on android 4.2.2
didnt do anything since then.
now i want to change my rom to a new one (cm11) which is based on android 4.4.4.
every rom higher than 4.1.2 is required to have bootloader 4.2. i dont have 4.2, i have 4.1 and i dont know how to update it to 4.2.
that my main problem.
every "new" recovery from the past year requires 4.2 bootloader and i dont have it so im stuck with "baked" rom which now giving me a hard time.

anyone?

You need to flash stock ROM in order to update your Bootloader.
Here's a similar thread: http://forum.xda-developers.com/transformer-tf300t/help/want-to-to-stock-rom-t2861116

what can i do in order to update my device to cm11 or 10?
its driving me crazy!!!!

What did you do so far?
It's basically just flashing the stock blob:
Code:
fastboot -i 0x0B05 flash system boot.blob
You can always wait for lj50036 and see what he suggests. He's the expert

if there is a video on how to flash a stock rom (downgrade) from 4.2.2 i would love a link for it
thanks!

Read the thread I linked again. You don't need to follow the whole guide to go back to stock:
"skip to the fastboot erase system command and go from there ..."
If you are unsure about the bootloader versions, just flash the stock ROM you had before and let it update itself when you are booted up in Android

[Q] New user - German Xoom in DK (MZ604) no ICS update

Hi everybody
Returned my Prime because of a lot of reasons and now I've ended up with a Xoom
This is my first tablet.
But why cant I see/recieve the ICS update?
I chose Danish as language, is that the reason?
Model: MZ604
Android-Version: 3.2
Tell me what u need to know, or what I have to do
Thx
is it a bad thing to make it a GED device? Got the guide ready.
Im using it in Denmark. Does that mean anything? Im not going for custom roms rigth now. Maybe later
Plz answer!

'cause there just is no ICS update for any xoom that supports more than wifi
forget what I said. I kind of read MZ601... Clearly, your model is a Wifi-only-xoom. I am not sure though if this (the european) version should already have received the ICS upgrade. Some sources I found state that it will be released in Q2/2012... However, another pointer I found was: are you positive your xoom is not unlocked (/are you the first to own it)?

if you have fastboot set up on your computer reboot your xoom into bootloader mode (for example by entering adb reboot bootloader in a windows terminal, after all, if fastboot has been set up, adb is most likely also set up; USB debugging must be turned on in android settings for this) and once the xoom rebooted into bootloader mode just enter fastboot getvar all, that should return something like
Code:
...
(bootloader) battery-status: 61%:7.671V:0.9844A:21.75C
(bootloader) unlocked: yes
(bootloader) iswarrantyvoid: yes
all: Done
finished. total time: 0.547s
unlocked will be yes if the device is unlocked and no if it isn't; iswarrantyvoid will be yes if the device has ever been unlocked.

that is correct. You can re-lock your bootloader if it isn't locked, but you need to have stock everything for that to work (/system /recovery /boot)
Trackid worked which i read meant it was locked
there you go.
Not unlocked!
Why do you prefer stock rom? The custom roms work great. If you want a rom that is very close to stock I'd recommend TeamEOS 1.0.
I dont say I dont want a custom ROM soon, but I would like to try the official ICS first.
And I cant figure out why I dont recieve the OTA update? Is some of my infos wrong regarding the screenshots I've posted?
decided to go the custom room way..
but need some help!
What to do after I have unlocked the bootloader?
I've downloaded Eos wingray and the eos Gapps.
Havent done this before
Did you install ClockworkMod recovery? If so:
-place the EOS rom and Gapps on the external SD card
-make a backup of your stock rom
-do a wipe/factory reset
-flash the EOS rom
-flash the Gapps
-reboot your Xoom
kunddizzle said:

Click to collapse
after you unlocked your bootloader you have to flash a custom recovery (I recommend the recovery linked in this thread), then boot into the recovery and flash the custom roms .zip and the gapps.zip. To do all that, you can just follow the instructions in that thread, just don't flash the xoom-root.zip, instead flash the team EOS-zip and the gapps.zip
If I was you, I'd make a nandroid backup right after booting into recovery for the first time, you could use that backup to restore to stock later on, if you like. This will even overwrite your custom recovery once you boot it, after that you can lock your xoom again.
tl;dr
put roms zip-file(s) onto SD-Card
unlock bootloader
flash recovery
boot recovery
(optional) Backup everything
flash the roms zip-file(s)
I decided to test the US GED ROM first.
Then I have something to compare with!
Thx for the guide. Will use it soon!
If I want to download the german or european version, can I use those listed here?:

Stock in the Asus LOGO! After i rebboted by holding the power menu and volume down, i choosed the wipe option ( i dont know why) and from tht time, it rebbots only in the 6.0.2.3 CWM what ever i do!
For 5 days, i have tried to flash via fastboot twrp.blob, i have pushed the firmware from asus to /sdcard and flashed via fastboot always, i have tried and read similaire problems! didt succed! i have always the message tht Can not mount sdcard! cant mound E/data! cant mount anythingg!! What ever i do, always reboot to this CWM !!!!!
please any one help me!!!!!!! thanks a lot!!!
You have installed an incompatible older custom recovery on the 4.2.1 bootloader. What you should have one is downgraded the bootloader from the energy thread to 4.1.1. You didn't need to downgrade your recovery.
Anyway I think you have bricked now.

but i can use adb commands, and fastboot commande ( except tht i have waiting for device each time) so its bricked for EVER?!
You appear to have the same brick as everyone else. Caused by an older recovery on the latest bootloader.
If you can get fastboot to accept a lower bootloader or get it to accept TWRP 2.4.4.0 you should be able to recover but as you said it won't accept anything........

How are you trying to downgrade? Can you get to the booloader? If yes, try this:
In bootloader, wipe data
Reboot into bootloader
Then, using fastboot, flash system blob from Asus stock ROM using fastboot (fastboot -i 0x0b05 flash staging blob)
If that succeeds, flash appropriate TWRP from bootloader using fastboot, then flash bootloader compatible ROM
If it only (re)boots to recovery, then you'll have to hang in there until a solution is invented. Until that time, you're bricked

You wouldn't be bricked if you had read the instructions and followed them to the letter (and ask questions when unsure).
With that in mind - you can just as easily brick any device.

No that's just wrong for a bunch of people. At the time I did it. There was no warning, no indication of any problems. Just decided to do it at the wrong time. If it was 1 day later, I would have seen the bricked threads or had the patched TWRP.

Wrong? No.
Harsh? Yes.
Read read read. Learn learn learn. Then read some more. When unsure, ask questions. Don't just try, then read the manual tot learn how you screwed up...
I am unsure tot flash 4.1 bootloader based roms through the 4.2 patched TWRP. I am NOT just going to try, I am awaiting an answer for 3 days now.
Is a Tab(2) as easily to brick as a Transformer? Yes it is.

As long as you can use fastboot, replace it with the version that works on your bootloader:
TWRP 2.4.4. 0-4.2.
CAREFUL: A lot of people bricked their tablets in this state.

OK, so flashing fails silently for some reason.
Do you see the blue flash bar on the bootloader screen, when fast boot says "writing"?
Never had any fastboot issues on Linux, but I have seen lots of people having issues with drivers on Windows. If you are using Windows, you might want to read up, how to make sure you have the proper drivers installed.
Short of that, no idea. :-/
Maybe can you post the full output of fastboot?

Make sure you're using the newest fastboot. There may be a bug on your current version.
Back in August I soft-bricked my tablet - no recovery and no ADB access. Fastboot would turn on on the tablet, but fastboot on my computer (Debian) kept hanging on "waiting for device". I had used fastboot on the same computer a couple weeks earlier to flash a recovery, and lsusb showed all the correct device info, so I thought fastboot was broken on the tablet and I was SOL. Well, fastboot got added to the Debian repos at some point, and I installed that version. 8 months and 2 fastboot updates went by before I even attempted to fix my tablet again (2 weeks ago), but somehow it worked, and I now have an awesome tablet to play with. I have no idea what happened with fastboot when my tablet first bricked, but I can only assume that one of the fastboot updates fixed a nasty bug that only showed up when I bricked the tablet.
I know your device is being recognized by fastboot, and your situation is much different than mine was, but you could be experiencing a completely different bug.

In your bootloader, what version of ASUS firmware does it say you are running. It makes a big difference for which version of TWRP you should be using.
edit:
sorry in your first post i could see you listed it, I think you may be getting this besause you dont have the TWRP version for 4.2 jellybean. the versions that are compatible are labeled -4.2 at the end.
here is the link for the right twrp for asus firmware 10.6.1.8 - http://techerrata.com/file/twrp2/tf300t/openrecovery-twrp-2.4.4.0-tf300t-4.2.blob

at first i didn't install the correct TWRP but now i can't even flash the correct one that's my problem
I believe this may be the same issue that alot of devices suffered from when the 4.2.1 update first came out.
Here is a thread on the issue
http://forum.xda-developers.com/showthread.php?t=2179874
From what I understand it seems that the 4.2.1 bootloader changed the way that the partition table was setup and thus all previous versions of custom recoveries could not mount any partitions (twrp would ask for password & not be able to mount any partition & cwm also not able to mount any partition) and a new twrp-4.2 version had to be made specifically for the 4.2.1 bootloader.
Still not sure as to why this caused the fastboot issue with the majority of people that flashed an incompatible version of twrp or cwm.
The fastboot issue I am talking about is that when you use the "flash" command everything will seem to go fine , it will say writing... and successful on the command prompt but you will not get any blue progress bar on the tablet itself and after the flash command has completed the fastboot reboot command will not reboot the tablet. Which I find very odd as other fastboot commands will still work without issue.
The only know solution if this is the issue you have is to replace the motherboard.

Well, don't give up yet. That there is no known solution does not mean we can't find any.
If fastboot is broken, can you access via adb, while in recovery?
Also there was a thread on unbricking with fastboot issues. Might try that:

I'm in the same situation that you're in. I can send simple fastboot and ADB commands to the tab but as soon as I try to write anything, it just freezes and requires a hard reset. You'll find that you will be able to erase and send simple reset/info request but no write commands. You'll be able to erase your recovery partition but you will not be able write anything new to it. Good luck!
I ordered a MB from ebay last night. Now I just need to find a guide on replacing it.....

One way is to use fastboot to flash the latest 4.2 stock ROM. The bootloader is also upgraded in the process. Then you flash the 4.2 TWRP and whatever ROM you want from there.

I've used fastboot before, but a little more info - where can we find the 4.2 stock ROM? I followed a few links off this forum that took me to ASUS support page that stated you must select your OS (which there was no option).
Is there a thread dedicated to this?
I'm sitting on CleanROM (my Aunts), and over time, I guess this thing runs like a pig (so does my mom's stock 4.2 tablet). I am looking to make these two devices actually useful again.

OK, so with this 4.1 modded tablet, if I take the latest version of 4.2, grab the blob, and do the following:
Code:
fastboot -i 0x0B05 flash system blob
fastboot -i 0x0B05 reboot
Is that going to work, or am I going to end up with a brick?
I know that there has been some warnings on upgrading to 4.1 with 4.2 files, so I want to double check before I make a bookend out of this thing.
EDIT: Pulled the trigger - worked out fine. Now I will install a recovery and we'll be good to go!

Update from 4.1 to 5.0

Hey guys, posted in a few threads but starting a separate thread to keep my issues out of them.
Anyways, my tablet is out up date and I havent kept up to speed on the last 2 years worth of developments. So im looking to upgrade my rooted and unlocked tablet on 4.1 to the 5.0 rom. My twrp version is 2.3.3.0.
How would i go about updating to a 4.4/5.0 compatible bootloader and recovery?
Ive been advised to update the bootloader, but should i flash the boot before the updated twrp or the other way around? While we're at it, I've noticed the nvflash tools. I'm assuming doing the nvflash stuff would help me recover from any possible bricks?
Any help would be appreciated.

Yes here you are ....
Get the SKU from your bootloader screen .....
Then go to the Asus website and get the firmware for your SKU ending in 27.5 ...
Then unpack the zip and there will be another zip unzip it you will find a file called blob ....
Flash this blob from fastboot ...
Let me know if you need any help along the way..
Thx Josh

Thanks for following me around my 3 posts, lol.
Quick questions:
1. Should I flash the bootloader BEFORE flashing the updated TWRP? Or does the new TWRP get flashed before the bootloader.
2. When I flash the new bootloader, will i still be able to run 4.1 on the tablet (i.e. is the new bootloader backwords compatible?)
3. Will the NVFLASH stuff help me in the event that I do mess something up? Seems like it supposed to be a brick-proof safety net in case something goes wrong.
thanks for the help man!

1. The blob file contains the SOS which is the stock recovery, so flash TWRP after ....
2. No you would have to revert back to a 4.1 bootloader to do that ...
3. Yes I would highly recommend doing this ......
4. If you need any help ever shoot me an email we can hangouts [email protected]
Thx Josh

Thanks Josh, I think I know what to do now:
Step 1: Set up NVFLASH and get my backup files.
Step 2: Flash the 27.5 Bootloader using fastboot.
Step 3: Flash TWRP openrecovery-twrp-2.8.1.0-tf300t.blob
Step 4: Wipe system/cache, etc
Step 5: Flash Katkiss 5.0
Is this correct? Am i missing any steps in there?
Looks like you're not on hangouts right now, shoot me a message if we can chat. [email protected]
So, Josh TOTALLY hooked me up on this issue. Not only offer his help, he actually walked me through the entire process watching my screen through screenshare. I'm now up and running on Kitkass 5.0.... sweet sweet lollipop goodness.
Not sure how to edit the title to solved, but maybe a mod could do that?
