asus tf300 unlocked bootloader with jb. how to downgrade to ics?

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...
Sent from my ASUS Transformer Pad TF300T using xda app-developers app

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???

Clockworkmod Recovery or TWRP Recovery, what's better?

I have a TF300 with OTA Jelly Bean, unlocked, rooted and with ClockWorkMod Recovery installed, i want to know what is the best recovery to flash ROMS (ex: Hydro JB).

I don't know that there is best. They both do it. I'm a new user of recovery in general, and I chose cwm. Twrp seems to have a tad more under the hood, like a keyboard built in, but both will get the job done for you.

Twrp is a lot faster at doing backups

How can I get back to a stock ASUS .26 boot from AndroidRoot?

Hey guys,
So I recently did the procedure to enable NVflash on my TF700, and flashed the AndroidRoot bootloader in the process (over my stock .26). Unfortunately, I forgot to make a backup of the bootloader before doing that.
My question is, is there any way I can get back to a stock .26 bootloader now? A bootloader image file I can download somewhere? I want to do so to get back to stock .26 firmware and then upgrade to stock Jellybean.
Thanks

I'm really curious as to *why* you'd want to do this... If you just want to get to Jelly Bean with the stock bootloader, you can download the full JB firmware from Asus now (it's a FULL install, not just an upgrade like the OTA was) - it will replace the bootloader as well.
I just can't think of any valid reason to revert to the .26 bootloader just to get to get back to the stock bootloader in order to upgrade to JellyBean/stock bootloader.

So can I just run the Jellybean installer to return my tablet to stock (keeping bootloader unlocked of course)?
By the way I have TWRP recovery. So I need to change to stock recovery first to run that file, right?

Actually, just installing the stock JB image from Asus will replace your bootloader and your recovery, so no need to change to stock recovery first...

But I can't find a way to run the ASUS update, since I have TWRP recovery (seems like it requires a stock recovery)... If I start the update from within Android, it just takes me to TWRP. How do I run the file?

Never mind, I just tried installing the ASUS update file from within TWRP, to my great surprise it worked! I thought it was going to brick my tablet, honestly (I have an NVflash backup so no worries). Well, I'm happy, thanks for your help, jtrosky.

after install cleanRom 3.4.6 cant boot

i have a TF300t upgraded to stock 4.2.1 with bootloader unlocked, with twrp 2.4.4.0 rooted, trying to install the cleanRom 3.4.6, successfully installed but was not able to boot (stuck on boot screen), i read on another thread that it is due to the bootloader of the 4.2.1 is not going to work with the rom. is it that if i install the CROMi-Xenogenesis 4.3b4 ROM then it should boot fine?

Yes mate you need to use cromi-x on that bootloader

I did exact the same thing, installed cromi-x (without the patched kernel option), install successful, but it sill doesn't boot.
any idea?

[Q] TF700 Stock Recovery

This question might be posted somewhere else, and if so, I apologize.
I recently unlocked my TF700 and installed cwm. I didn't realize this would disable the OTA updates. Is it possible to re-enable the OTA updates while keeping cem installed? If not, what is the easiest way to uninstall cwm and re-enable the updates?
I am currently running the 10.6.1.14.8 firmware with a US sku.
Thanks in advance!

After unlocking you will not be able to receive OTAs anymore, not even if you flash back a full stock firmware. Unlocked bootloader = No more OTAs

Thanks for the quick reply. Will it still be possible to upgrade the firmware and still keep root?

Yes - but why would you run the stock firmware if you are unlocked and have a custom recovery???
Both CM roms or CROMi-X run circles around the stock rom.
But if you insist on running stock: You can flash the latest Asus firmware in your recovery (full disclosure: I have only used TWRP, don't know anything about CWM but assume it's the same - research it though).
CWM will be replaced with the stock recovery if you flash the full firmware, so you have to flash CWM or TWRP in fastboot again, then you can flash a Superuser package in your custom recovery to gain root.
But it would be so much easier to just flash a custom rom from your current setup - any specific reason you don't want to try it?

You can forget about all the root keeping hassle after unlocking, you will be able to root anytime.

It was more a curiosity thing than anything. I haven't had much time lately so I was sticking to what was familiar. Once things slow down, I plan on playing around with custom ROMs to see what I like best. Do you have any recommendations?
