[Q] Bootloader Upgrade - Transformer TF300T Q&A, Help & Troubleshooting

So my tablet is currently on the 10.4.2.17 firmware for the bootloader. I need to upgrade it to the latest. How would one go about doing that without flashing back to stock? I am currently on CM 10.1. Is there a way to only flash the bootloader to the tablet?

Well I flashed back to stock to upgrade. Oh well, haha

I think it was mentioned in the cm10.1 thread that flashing back to stock is the only way

Correct, there was however a bootloader update that was standalone but it was an old version.

Question on updating from 4.1.1 VBRBLK3 to 4.1.2 VBRMF1

I have a rooted Verizon S3 that is currently on 4.1.1 VBRBLK3, I would like to upgrade it to 4.1.2 VBRMF1. I understand that I can use Odin to do a full rom flash however but I don't want to go that route, I would like to use the apply the update using the recovery option . In order to do this, do I need to appy the updates in sequencial order? Like update it to VBRMB1 first and then VBRMF1 or I can apply VBRMF1 directly to VBRBLK3?
Thanks,

Are you rooted AND unlocked? Do you have a custom recovery? If so, you could just flash the rooted stock VRBMF1 rom posted by Scrosler.

Or you just go grab the modem/radio from the stickies and flash in recovery.

That's the complete stock rom that you're referring to, not just an update zip file, right?

Since its a rooted zip, it will upgrade the software to VRBMF1. Your baseband (Settings/About Phone/Baseband) will still read VRBLK3 so you'll need to flash the firmware that Sandman-007 just posted about. As I said before, this will only work if you are rooted AND unlocked. If you haven't unlocked your bootloader then do not try this method.
To answer your initial question in your first post, you can take the OTA which will unroot your device. You can then use Casual by beanstown106 to root/unlock again.

I think I have found both files now. Just to be sure, these 2 files are:
I535VRBMF1_I535VZWBMF1_VZW.zip (around 820MB)
d2vzw_VRBMF1_firmware.zip (around 20MB)
Does it matter which one I do it first?

Looks about right. The flashing order does not matter. I prefer to flash separately with a boot into the rom between flashes whereas others would flash all at once. Personal preference really.

You need to tell us what rom version you're running? Go into settings->about phone and report the rom version.(like 4.1.2 or 4.3 etc..)

Is this true for all 4.3 or just those with Knox? Last night I was trying to update from cm10.2 to cm11 and realised that trwp needed an update. After a some failed boots pf cm10 and 11 I decided to just go back to stock since I need it during the day..and unknowingly put the dreaded 4.3 on via odin. I understand how to get root...but what I really want is my bootloader again. Did I screw myself by putting 4.3 on? Thanks.

You're stuck on 4.3 now, your bootloader is locked. Using Odin to load a stock 4.3 firmware is the exact same thing.
You should've odin'd a stock 4.1.2 firmware, but it's too late now.

I'm in the same boat with 4.3 - rooted with saferoot, but when I went to download safestrap to flash the only customs roms I can (TW), I don't see a download for the SCH-i535. The closest I see is for S4. Where can I get the right Safestrap download?
Thanks for your help.

Awesome. This is exactly what I was looking for. I'm pretty set on doing this now, but I'm trying to find a solid rom to flash once I get Safestrap. Any suggestions? All I've found so far are S4 roms. The Google Play Edition rom looks pretty good.

Don't flash any ROMs for the S4 onto your S3. Through safestrap you can flash almost any of the 4.3 TW (ML1) ROMs found in this section:

If he rooted his Verizon S3 on VRBMF1 4.1.2, then he could use EZ Unlock v1.2 to unlock the bootloader. Or he could use Casual.

Great. Now if they accidentally or intentionally take the 4.3 VRUCML1 OTA, using EZ Unlock will cause a bootloader hard brick. Please make sure your friend understands this.

I have all ready tried there only one I have seen and tested is rogers. The only reason I am looking for it is that I need to update to kitkat and get the 4.4 boot loader so I can get the latest version of CyanogenMod. any other way to do it would work to but It needs to be for the XT925 Not the XT926.

I have flashed CWM fist and tried to install CM12 but it failed and displays that I need 4.4 bootloader, which I found out while searching that I need to install kitkat fido update first but I installed CWM before doing the up date and now I am unable to get 4.4 bootloader without removing CWM and from what I can find I need to flash the stock fido rom in order to remove CWM.
Just flash and then OTA update to 4.4.2 from http://web.archive.org/web/20130817...12.2_CANADA_VANQJBLTEFRCI_P004_CFC_fb.xml.zip
Rogers or Fido, it shouldn't matter.

You're flashing the wrong one. There is a jbbl version for your device for CM12. Even though i'm on an AHD, i'm running your device's CM12 (925's CM came out first and i've been running it since its release)

bootloader 10.6.2.12

Hello i have my tab unlocked with andoid 4.2.1 and bootloader 10.6.2.12, i want to flash recovery/root/cusom rom do i need to downgrade bootloader ?
That's the latest bootloader for the TF300TG, this forum is for the TF300T and the latest BL for that one is 10.6.1.27.5.
I don't think any of the roms in this forum work for the TG, but I'm not positive. Do some research on that...

Please start fastboot (Power on and Vol. down). In the left corner above of the display a message like "WW_epad-10.6.1.27.5-20130902" should appear. If so, the device is on the last Asus firmware JB 4.2. and has the right bootloader ending 27.5.
It reads Android cardhu-user bootloader (1.00 e) released by "TW_epad-10.6.2.12-2014103" A03

On this tablet??? With that bootloader? Or did you at some point flash the wrong bootloader to your tablet (if it actually is a T - not a TG)?
If you had Katkiss running you could try the same combo you had then. Whatever recovery version you had and then try to flash a rom. But be aware that the wrong bootloader/recovery combo can be fatal....

Then I would bet your son flashed the TG Asus firmware instead of the one for TF300T. They are identical in hardware except for the radio in the TG model.
I would recommedn you get it back on it's original firmware. So you would flash the stock blob from the 10.6.1.27.5 firmware in fastboot. Just follow the last part of the instructions for the buster99.
Once that is done you can flash the latest TWRP for the TF300 and then your choice of Katkiss, Katshmallow or Nougatella.
timduru is the last developer still working for the Transformers. I would go with one of his roms. They are all great!

Yes. You can skip the erase commands and go right to flashing the system blob. It'll overwrite everything anyway and you don't have a troublesome command stuck on any partition, so the wipes are not strictly necessary - but they wouldn't hurt either.
Actually - you probably should wipe userdata before flashing the blob and that command is missing from that post:
Code:
fastboot erase userdata
fastboot -i 0x0B05 flash system blob
