[Q] What is the best upgrade path from HC to ICS?

My Transformer has been playing second fiddle to my iPad for a few months now (shoot me) and I have never upgraded it to ICS. I am at 8.6.5.19 with CWM 3.2.0.1. Is there an easy way to go from HC to ICS?
What upgrade path should I take?
Thanks!

Figuring out which release bugs you want to live with if you stick with the Asus rom, will be the biggest question

I usually am satisfied with the stock rom, rooted. It shows 9.2.1.24 as the latest. is it simple as just loading the rom through CVM? Am I over thinking this?
Can I go from 8.6.5.19 to 9.2.1.24 via CVM that simple?
Thanks!

OTA upgrades won't work with CWM

I know. I was wondering the way to go from 8.6.5.19 to current. I see there was a ROM to upgrade from any ROM to 9.2.1.11 so I guess I am gonna try that. I was wondering if there was another way to go.
Thanks again.

Sorry, didn't fully read. Not sure if the stock from will install with cwm. Maybe someone else will answer. Otherwise you will have to do a complete nv_flash to install a stock pics rom

You don't want to flash an ota from ASUS, unless you remove the SOS partition of the blob, it will make you lose your CWM recovery and you'll need to reroot. Since you're rooted and whatnot, why not try out one of the amazing custom roms in the development forum? You can get a rom that's based off stock (looks the same, based off official otas) with extra features and tweaks, and most of all considerably less bugs. If you want stock flavour, I recommend ARHD or Revolver 4.
The process:
Download the rom's .zip file to your External SD card (since you have cwm 3.2)
Download superwipe.zip from ARHD (Should do this, it's more in depth than a normal wipe)
Run the superwipe script by installing it from the sd card, this will COMPLETELY wipe your tab.
Go to wipe, hit wipe Cache.
Go to Advanced, hit Wipe Dalvik-cache
Go to wipe, hit wipedata/factory reset (just in case)
Now install zip from SD card, and install the Rom.zip.
Power off your tab, then hold vol-Down and let it Cold-Boot. It will take a few mins to boot.
Once you're in, set up how you like and let run for a min.
Download Guevor's V20.1 or Test17c kernel from Development and put on microsd.
Go back into cwm recovery, wipe cache and dalvik cache again.
Install the kernel .zip from sd.
Cold boot again, and all set
This will give you probably the most stable ICS you can get, the kernel is important too, even if you decide to stay stock rooted, you should flash the kernel IMO to fix bugs. Sorry for long post xD""

with TWRP for JB,no rom worked,help!

my English is poor,apologize
I have a tf300t(bought from US,I am a chinese),it isn't unlocked until update to stock JB(i update to 4.1.1from OTA,locked),but after unlocked,I flash the CWM 5.5.0.4,but it didn't work.Then i flash the TWRP 2.2.1.3 for JB only(http://forum.xda-developers.com/showthread.php?t=1843694),it worked.But after i flash the fireware "ASUS-ICS-HYDRO-PONIC"(http://forum.xda-developers.com/showthread.php?t=1750861),after reboot,the device hanged at the asus logo for a long time(i watched it for even 10 minutes.....),so i tried the stock rom(download from ASUS site,US_epad-user-9.4.3.30.zip)but it didn't word too.Now my tf300t can't boot to the OS,it only can get into the recovery(TWRP2.2.1.3 for JB).somebody help me......,I wonder if it is the update from OTA to cause my problem)

There are others in the same situation. Keep watch on this thread http://forum.xda-developers.com/showthread.php?p=30516010
And others. There should be a fix soon to downgrade back to ICS and start over. Hang in there and be patience. At least you can get into TWRP so there's still hope.

yes it worked,my tf300t is unlocked,there is the word"this device is unlocked" on the asus logo screen.but it can't load os.

So I wonder if maybe you would have luck wiping and trying to install a jb based ROM like cm10? Since you're already on jb firmware its understandable that an ICS ROM fails... I'm by no means an expert but just someone considering an unlock after JB ota

Looks like partition sizes chaged with the Asus update. I couldn't flash CM10 or any other rom as well (signature mismatch). If you installed the official 4.1.1 update, you need to manually install it again. Older versions and rollbacks wont work unless you push to some trickery mmcblk0p4, but that's another thread in itself
Download the JB update from Asus's website (if you still have it, that's fine) and extract the blob file. Put the blob file in teh same directory as your fastboot. Boot your TF300 into bootloader and enter:
fastboot -i 0x0B05 flash system blob
It will take a while to install, so be patient. Hope this helps

Not yet. This fix is in the works. The new custom recoveries need to be modified for OTA JB first. Keep an eye on the development threads.
Sent from my Amazon Kindle Fire using Tapatalk 2

So if you put all these steps together...
1. Update to JB using OTA
2. Unlock
3. Flash TWRP
4. Flash extracted blob
You have an unlock/custom recovery method for those of us on JB am I correct?

yes exactly! but you need flash the TWRP again after flash the extracted blob,or it will be the stock recovery.and then you can flash the ROOT.zip.So the device will be rootd.

[Q] Looking to fix these problems

So I own an Asus TF300T and I'm using Jelly Bean [Rooted 4.1.1]
Here are my current problem's.
1) I am unable to get CWM to work on it as it will install correctly through Fastboot but when I reboot into Recovery it will hang t the RCK screen. I don't know how to fix this as I've tried a few different recovery images, all of which were CWM.
2) When transferring via Bluetooth to my Nexus 7 the TF300T will reboot for some reason... same thing happens when I'm sending files from my N7 to the TF300T. Any idea's as to why this would be happening?
3) I am unable to reset my device to stock, has anyone else had this problem?
4) I have minor time's where the device will just reboot because of what I assume to be the processor taking on to much of a load from the Android OS. Is there a fix for this problem?
Any answer's or solution's would be helpful. Every time I find what I think to be a fix doesn't work...

1) What bootloader are you running from? [Edit: Sorry, forgot you mentioned you are on Jelly Bean there -- You will need to make sure the CWM is JB compatible (again look at the link I posted here for the CWM JB Recovery)] If you are on the new JB bootloader you have to have CWM recovery that recognizes this. I don't use CWM on my TF300, but you might try HERE to find info on that. I do know that TWRP version 2.2.1 and higher have a JB bootloader version. You can find it from their site HERE.
2) No clue on the bluetooth. I don't use the bluetooth transfer so I haven't ever tried this out.
3) By "reset device to stock" do you mean the Factory Wipe Data option from the boot menu, or something else? Please explain and I'll do what I can to assist.
4) I've had my device reboot a time or two for no reason, but I don't know enough about debugging things in the software to know what's going on.

Hey nate, thx for the reply, but by "Reset to Stock" I mean ou download the original stock image and re-flash the original firmware...

Being that you are already on the Jelly Bean bootloader, you cannot flash any firmware to working condition that is not a Jelly Bean bootloader. This means that you can only flash 10.4.2.9 or 10.4.2.13 firmware versions. Anything else won't boot on the JB Bootloader. Also, the ZIP file you might download from the ASUS site requires it to be unzipped first. There is another zip file inside of the downloaded file that is used for the actual flashing process.
-Nate

Yup I know that part...
Just confused as to the process of getting it done...
I have some experience in flashing new firmware but with the TF300T I'm so confused xD
Sent from my ASUS Transformer Pad TF300T using xda app-developers app

There isn't anything "rocket-sciencey" to flashing on the TF300. If you have ever done any type of ROM flashing, the returning to Stock is the exact same way, just using the stock firmware file downloaded from ASUS.com. Find the firmware you want to load, download and unzip the file to a YY_epad-X.X.X.X_2012xxxx.zip where the YY is your location code (US more than likely) and the X.X.X.X is the version of the firmware you are loading up. The xxxx should say "user" if memory serves correct. Put it on your MicroSD and flash it like you would any normal custom ROM. Wipe Data, Wipe Cache, Flash ROM, Wipe Dalvik, Reboot. I'd be happy to put together a more fluid tutorial on this if needed.
-Nate

I didn't see anything from US so I tried WW.....
Sent from my Nexus 7 using xda app-developers app

If you go to asus.com and click on United States, then go to the Tablets and the TF300 download section the only ones available should say US. But I think WW should work, no guarantees though.

I'll try that today thx...
I'll post back later

[TWRP&CWM/Install JB OTA from custom recovery] Jelly Bean OTA for Unlocked Devices

[TWRP&CWM/Install JB OTA from custom recovery] Jelly Bean OTA for Unlocked Devices
Hi guys,as you may know,if you unlocked your bootloader you won't be able to receive OTA's anymore so you have to wait for Asus to upload the firmware on their site.Or even better you can use your custom recovery to flash a modified OTA pack wich will update your device just fine.
Warning:
** I'm NOT responsible for any damage caused to your device by using these files so use them on your OWN risk.
** This update will also flash the Jelly Bean bootloader so if you are still on .26 bootloader and you didn't used the NvFlash tool yet,well,it's time to do it because after installing this update there's NO WAY to go back,yet.
** You Custom Recovery will be replaced by the Stock Recovery (You can install this CWM Recovery after installing JB)
** I only tested with TWRP but it should work with CWM recovery too
** Verify your MD5 checsum after download
Requirements
* Your device must be unlocked and rooted
* You need to be on STOCK 9.4.5.30 ROM with no modifications to system files (build.prop,etc) (no need to do the Factory Reset)
* Use OTA RootKeeper before installing this update if you want to keep ROOT
Installation
1) Download the file for your specific SKU
2) Move the downloaded file on your internal or external storage
3) Boot your device in Recovery
4) Install the update / That's it,wait for the install proccess to finish
NOTE: If you are getting errors and you are using CWM recovery try renaming the file (i.e TF700T WW_10.4.4.16-20120927 OTA.zip - - > TF700T_ WW_10.4.4.16-20120927.zip)
Download Links
WW_SKU --- > TF700T WW_10.4.4.16-20120927 OTA.zip ----- MD5 checksum: 9d4e1e91a08254256357eb2870d2df7d
US_SKU --- > TF700T US_10.4.4.16-20120927 OTA.zip ----- MD5 checksum: 4131cab5458153856185c43e05b67ebe

Because the update will fail to install if some system files are missing or beeing modified.Please don't try this on custom firmware,but if you do,just don't complain about it in case is failing or even worse.

Asus OTA updates aren't a complete replacement. Instead the update performs a patch to your existing files. A non-stock or non .30 version may cause a failure during the update process.
Truthfully if you're running an unlocked device you should wait for a ROM developer to make a new ROM and use that to update instead of trying to flash the Asus official update. It should only be 24 to 72 hours and a ROM won't do things like remove root or replace your custom recovery with the stock recovery.

Works 100% with CWM recovery!
Thanks a lot My friend!

I can also confirm, this method works! I`m on jelly bean now

Quoted for fiction
It's fine to flash if you are on stock .30. Replacing the recovery costs about 30 seconds, and replacing root on an unlocked device takes about 30 seconds as well. Then you can evaluate an Asus jb yourself before seeing a custom jb.

Can't Flash CROM 4.1 please help!

I am having problems flashing Clean Inheritance Rom 4.1 and I believe my TWRP 2.4.4.0 may be the problem because it seems corrupted.
I followed the instructions on this thread. http://forum.xda-developers.com/showthread.php?t=2187982
So far I have been able to flash the patched twrp 2.4.4.0 and install the Asus stock 4.2.1 but every time I try to flash CROM 4.1 twrp will initiate updating partition and then it will just restart w/o warning to its home screen. I think that my twrp may be corrupted but i have used fastboot to repush the twrp multiple times and the asus stock 4.2.1 multiple times but this is not solving my issue. I see that fastboot has a erase command and wanted to know if i would use that to erase the recovery img completely and then try flashing twrp again to see if this resolves the issue or will the erase command brick my device? Also do I need to have my stock kernel for the CROM 4.1 to work? I am attaching screenshot of my tablet info, please let me know if more info is needed or if i need to upload a video of what is going on thanks.

have you redownloaded twrp mate it might have been a dodgy download or maybe a bad download of cromi, or you could try installing cromi 4.0 first

Update! bump please help someone
I am still having issues installing clean rom 4.1 but I noticed that if I keep selecting to flash the CROM 4.1 or 4.0 rom it will eventually initiate and let me choose the options and actually start flashing but once it says it is complete and i reboot it does not boot CROM just gets stuck at the asus boot screen. Then i must use fastboot to flash the stock android 4.2.1 to get the thing up and running and then twrp pretty much breaks after i use fastboot to flash teh android 4.2.1 blob file so I have to reflash the patched 2.4.4.0 again. I really do think the problem is with twrp because ever since this new 2.4.4.0 update i have been having issues i remember before twrp was a great utility but now it seems like it is a nightmare is there a way from me to try flashing crom 4.1 with clockwork mod yet?

I was able to flash SuperSU as well
I was able to flash SuperSU and it was confirmed rooted with root checker. I still don't know why CleanROM will not work I have downloaded the ROM multiple times but it just refuses to flash is there something else I need to check in order to flash the rom or is TWRP partially broken where it can only flash very small simple files but not a complete custom rom?

I just downloaded the energy rom and tried to flash it do my device and ended up having the same issue. It says the rom has been flashed and completes but after reboot it is just stuck on Asus bootscreen and never boots into the OS. What the hell is going on

I think my bootloader is somehow screwed up because it can't boot any custom roms it can only boot the asus stock 4.2.1 when i flash the blob file using fastboot. Did i miss a step or something to allow the bootloader to boot custom roms
