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!

Yes, you can... It is a good guide if you can follow it.. You must make sure that you have the latest bootloader and compatible TWRP.. Those are very important so you are not brick your device... Good luck and ask all the questions that you have before trying to install the TWRP and bootloader...:fingers-crossed:

ok so i'm having a bit of trouble following this guide...
1) I installed TWRP (with the help of this page) http://www.teamw.in/project/twrp2/105 I had to use the Download - Recovery Image / Fastboot Method because the app method wouldn't download the blob file
2) Now, when I power + volume down boot I can see my bootloader isn't the correct version. how can I update the bootloader? I have the files from the original link i posted (http://forum.xda-developers.com/showthread.php?t=2481892) so there is the correct bootloader i just don't know how to install it.
is there a more detailed guide with actual step by steps?
Congrats on getting TWRP installed! The rest is easy.
In TWRP select 'Install' and navigate to wherever you have the zip file with the bootloader/TWRP package, select it (if it has xxx signed.zip in the file name you need to check the "verify zip signature" option. sbdags usually signs his zips - don't know if he did with this one).
Swipe the button to flash the file.
When it finished, boot back to system. Do not flash a rom at this point! That would cancel the bootloader flash. Boot back into system first, then back into TWRP and then flash the rom.
BTW - flashing the modified Asus stock rom is perfectly fine, but I wonder why you don't flash CROMi-X 5.2.2?
That rom is from the same developer, based on this stock rom and miles improved since sbdags debloated the stock version.
sbdags stock rom is not really supported whereas he puts out a better version of CROMi-X about every 10 days! It's exhausting to keep up! LOL
You'll find it here: http://forum.xda-developers.com/showthread.php?t=2425383
You can still flash the BL/TWRP package you downloaded already. It's the same as the one for CROMi-X.

Thanks, Honestly whatever custom rom I have now can randomly reboot and i think is giving me touch screen issues so was just going to hit up a stock install and see if that fixes any problems.
gonna try out the rom you suggested and i can always go back if necessary.
one thing, when i installed theTWRP the blue bar filled up completely and i left it for about 10 minutes and it was still there. so i powered down and everything booted back up correctly (and i can get into the recovery mode).
does everything sound ok to proceed?

You have to kick it out when it is completed by using the fastboot command or just using your power button.. So you are good to go...
You have to try out all the rom and kernels that are available then choose the best one that fit your need...Good luck...

[Q] Getting error when trying to downgrade to 10.6.1.14.08

Hi there,
I am running an unlocked TF700 on 10.6.1.14.10.
I am currently trying to get downgrade to firmware 10.6.1.14.08 in order to get root and to install custom firmware (stock Asus firmware is just too damn slow).
I've put the unzipped (it was a zip inside a zip) "WW_epad-user-10.6.1.14.8.zip" into the root director of TF700. When I reboot and the system offers me to downgrade, everything seems to be going okay.
But once the downgrade process begin, I get an error message (just a red "error" and a broken android mascot) and i have to turn the TF700 off and reboot back into the 10.6.1.14.10 firmware.
I tried downgrading my going directly into the boot / recovery menu and I get the same result.
How can I find out what's going on?
Thanks,
Levi
You probably have some system apps or bloatware frozen or uninstalled. The upgrade/downgrade checks for system integrity. If it doesn't find certain apps it will not install.
But why downgrade? Root doesn't help you getting a custom recovery onto your tablet.
Unless GooManager works again for flashing recoveries. Have read conflicting reports on that. If you go that route and it works, please let me know.
It is just as easy to flash the recovery in fastboot though. No need for downgrading either...

How do I find what I s causing this? I tried Clean Master but that didn't change anything. How can I get more info on this problem?
I following the instructions for the latest cromi ROM. they need unlock and root.

Go to settings, apps, and scroll over to the right, do you have anything disabled?
If so enable it.
It's probably easier if you block and follow the fastboot instructions to flash twrp and then CROMi-X.

You do need to unlock your tablet to run a custom rom. You do not necessarily need root.
If you are looking at a CROMi thread, you probably look at outdated information. CROMi was JB 4.1 based.
The same dev - the guy up there^^^^, sbdags - developed CROMi-X from the JB 4.2.1 base. That's the latest and greatest rom in the CleanROM lineage. His thread his here:
http://forum.xda-developers.com/showthread.php?t=2425383
Check out the OP for information how to proceed.
I recently wrote a little tutorial with current information on another forum geared towards users new to flashing custom roms. Maybe it helps:

Thanks, that last link is exactly what I was looking for. I will try fastboot once I am back home and report back.
P.S. the instructions for the current version of cromi don't reference the fastboot method.
cheers,
levi
Hummm, might be wrong here but if you want to downgrade the version unzip the file one time while it's on the PC rename the unzipped file to EP201_768_SDUPDATE.ZIP plug your sd card into the PC and copy that to the root of the sd card. Then try it.
Got CROMi running using the fastboot method. So far everything is working greater. The UI is much more responsive than with stock 4.2.1. The tablet is actually usable now.
I will provide more feedback in the CROMi thread once I get a chance to use it properly.
Thanks berndblb!

[Q] T300 install CM 10.1 and up to TWRP 2.7

I know this is the wrong place to post this, but everywhere else tells I can't. So here goes:
I've a T300 with AndroidBlue 3.0 and JB 4.1.1 on nit. Web browsing is typically slow.
I need to up TWRP from 2.2 to the latest and greatest, and would like some input as to whether or not going with CM 10.1 would help my "Browsing Experience"?
It seems that Rom Toolbox would take care of installing CM (or from TWRP), and TWRP Manager (with the right file - it dl's the ICS version) would take care of that.
Correct?
I'm sure this has been discussed before, but searching has yielded pages and pages that do not help.
All help have my thanks in advance.

OK so first you have to update that ancient bootloader of yours to use KitKat. Do that by flashing the latest Stock ROM via fastboot.

Thank you for answering - I've been ill since I wrote that, so I'm finally getting back to you. I'm looking at ASUS's site, as I can not find my build number (AndroidBlue over-wrote that in status) - but this is a US version, so I'm assuming 10.6.1.27.1 US SKU?
Can I not flash this via TRWP - I'm assuming Fastboot, just as when I flashed TWRP.
When I flash this will everything be back to stock: no root, no TWRP?

Hope you get getter
10.6.1.27.1 Will work, and I suggest flashing with fastboot so you can confirm that fastboot works so you can reflash TWRP later. When you do flash the 10.6.1.27.1 stock, everything will be erased, including TWRP, so you will have to flash a newer version of TWRP. That can be the stable branch here: http://forum.xda-developers.com/showthread.php?t=2772093

I don't see the "THANKS" button.......
Ok, so if I do this I LITERALLY start over, and should ASUS up another F/W version, I do this all over - correct?
Here's the REAL crux of the matter; I like the unit as it is EXCEPT that half the day the wifi sucks, either via 3g phone or RV park WiFi which I built! I'm getting closer to the reason for this, close my Dell 6400 down and the WiFi gets better, so interference.
OVERALL, would upping this one (I have 2) make any perceptible difference on the WiFi? I mean all else is fine.
So I need 3 things: newest F/W (have), Latest TWRP(don't have - yet but looking, 2.7 I believe), latest way to root(don't know) - Correct?
Again where is that thanks button!!!!!

Thanks button is below the username at the end of the post
Upping the tf300 would make the pages load faster on the tablet after they have downloaded, and would make Chrome or whatever other browser you are using load the page much faster. It would unlikely change the download speed to the tablet.
It's also unlikely that Asus will release another FW version because the tf300 is already 2 or 3 years old and they tend to cut support after that time. Then again, they could release an update tomorrow for no reason, but that doesn't mean the bootloader has to change requiring you to flash stock again. I updated my stock FW a more than a year ago and there has been 2 or 3 updates since that, but the bootloader hasn't changed so I haven't done any of those updates.

(The custom ROM is already rooted for you with the exception of Omni ROM)
Copy ROM to SDcard, flash in TWRP to confirm it works.
I would strongly recommend using KitKat over CM10.1 because KitKat is much mroe optimized for older devices, and you should see a performance upgrade.

Found my notes and kept reading system blob.blob, as renaming it to system.blob - gotta get new glasses.
Waiting for the media databases to upgrade.
Flash extract img from "CUSTOM_TWRP_JB_KK_v2.7_STABLE_TF300T"? to be sure
Just rebooted, and it's 4.2.1, but everything I had - most of what I had, is still there!?! And the run?

Yes the img from "CUSTOM_TWRP_JB_KK_v2.7_STABLE_TF300T" like this:
Code:
fastboot -i 0x0b05 flash recovery twrp.img
Dont forget to reboot after flashing the stock ROM and reboot after flashing twrp.

This should be the last question as the latest everything is on - no sweat really - bugged the hell out of your patience because I couldn't find my bloody notes till now.
So, the which KitKat (after a wipe) is the most stable - I've read through http://forum.xda-developers.com/showthread.php?t=2686228 and it would seem that the only obvious choice would be http://forum.xda-developers.com/showthread.php?t=2686228, but I can't/don't see the file!

That's the problem - WAY too many links ... I'm downloading the one in you response but that would be the latest CM nightly - correct?
I would rather have the most stable KitKat, as you've stated that works the best with my older devices. But which is the file for the T300?
SO, CROMi-X_DEODEX_5.4_Signed.zip as DEOdexed is a bit better. Now I assume as I can't do a nanobackup I can skip that , just do a Wipe Factory from TWRP.
I can't believe how easy this was when I did 4 different tablets and 2 phones and now ... maybe I was sicker than I thought.

I linked you to the latest build of CROMBi-kk, the updated version of CROMi. From the ROMs I have tested, it is the most stable KitKat ROM, assuming you don't want those cutting edge features.

Sorry misunderstood. While I've been waiting for the ROM to dl, I noticed that my notes have fastboot xxxxxxx boot recovery.img, yet mostly what I see is fastboot xxxxxx recovery recovery.img. I also noticed that when I do a Vol/Dn/Pwr I get the 3 icons and have to select RCK to get to TWRP - I haven't noticed that mentioned anywhere - did I screw up?
To be clear - I want wipe / and "swipe to factory reset) then flash KK.
I going to try VERY hard to leave you alone now - I have taken way too much advantage of your kindness in helping me.

I'm not sure what you are talking about with "fastboot xxxxxxx boot recovery.img, yet mostly what I see is fastboot xxxxxx recovery recovery.img". As long as TWRP is working you shouldn't have to use fastboot anymore.
The new bootloader that you upgraded to only has 3 icons when you press vol-down and power. Fastboot now connects automatically if you turn on your tablet with the USB plugged in and pressing the key combo. To access TWRP, selecting RCK is the correct choice. As always, never select the Wipe Data in the bootloader menu or you will brick.
Before flashing new ROMs, you should only have to do the "swipe to factory reset" option in the TWRP recovery. If you update your ROM with a newer version of that specific ROM, you only have to Wipe Cache and Dalvik Cache.

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 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

when i wrote:

it didnt gave me the right output, it gave me a long list of descriptions.
my main concern is that my android is 4.2.2 and my bootloader is 4.1 - is that even matter? is that could affect the "bricking" of the device?
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

You don't need to push that file to your tablet...
It's for unbricking your bootloader

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.

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]

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?
