Detailed Guide of Getting a Stock ICS Infinity unlocked

Hi Guys,
i decided to open this thread, because in my opinion my questions aren't really answered yet. So here is my question:
I have a Stock Infinity with 9.4.5.21 ICS Firmware and i want to get my NVFlash Files and finally install a Custom JB ROM on it.
But i don't really know in which order i have to follow the already postet guides. I think i have to do it as follows:
1. Unlock Bootloader with official ASUS APK
2. Gain Root (f.e. with the one-klick-root-tool)
3. Proceed with Nvflash (to make it Brick-Safe, because it seems that it happens very often)
4. Install Stock JB Firmware from Asus (But how to flash it?)
5. Flash Custom Recovery (f.e. TWRP with GooManager)
6. Flash Custom ROM (f.e. Clean Rom)
7. Be happy to have a non-bricked TF700
Can someone plz help me to verify these steps? I'm sure it will also help others who aren't certain about unlocking, too.

I would do this:
1. Unlock with the official tool and void your warranty, hope that Asus' servers work.
2. Root is not required at all for using fastboot or a custom recovery.
3. Do the NVFlash backups using fastboot and nvflash. Copy the created files from the tablet to your PC before you flash anything else.
4. Install a custom recovery using fastboot.
5. Flash the Asus JB firmware to get the JB bootloader. AFAIK this can be done from the custom recovery.
6. Restore custom recovery using fastboot, it was overwritten by the Asus JB firmware.
7. Flash custom ROM. If you use CleanROM, it's already rooted.

I see issue with your process. After step 4 (install Stock JB firmware from Asus site), after this you no longer have root/recovery, so you can't proceed to step 5 using GooManager. You should follow _that's recommendation, however at step 5, instead of flash the JB firmware, you just use fastboot to flash JB bootloader only, then you don't need his step 6. Go straight to step 7 (use custom recovery to flash custom rom).

Thanks for your help!
So now I think it should work like this:
1. Unlock Bootloader with official ASUS APK
2. Proceed with Nvflash (Afterwards boot into Stock Android to save NvFlash Files before continuing)
3. Install TWRP Recovery
4. Install JB Bootloader with ADB
5. Flash Custom ROM (f.e. Clean Rom)
6. Be Happy, because now it's unbrickable and ervery Custom Rom can be flashed
But i dont't know what I have to type into ADB to flash JB-Bootloader and where to get the Bootloader-Only-File?

PM me I give you JB bootloader zip file
No ADB, just use TWRP to flash JB bootloader just like you flash a rom.

I finally made it without bricking it
If anyone else have questions, feel free to ask me!
And thank you guys for your help

[Q] Acer Iconia A700 JB rooting

I just get my Acer Iconia A700 with android JB 4.1.1 installed.
I want to root it, but all I have found is for ICS 4.0.3.
I also want to keep the original rom.
Is it possible, just rooting, not flashing?
thanks in advance

There are a couple methods you can use, and still maintain the stock image.
Look at this thread;
http://forum.xda-developers.com/showthread.php?t=1953917
2 methods you can use.
a. The CWM method. This replaces your Stock recovery with a custom recovery you can flash zip files from.
b. Alternative method (keeps your stock recovery) This offers the least intrusive method of getting root.
CWM has been known to cause issues in the early days, but it seems the more recent versions have settled down. I still wouldn't advise making and restoring backups though. Just from my own experience.
The unsecure Boot.img (kernel) should be the method I would advise. This allows booting via "fastboot" (like when you unlocked your bootloader) and then "fastboot flash boot xxxxxxboot.img) Then you need only to get Superuser and busybox. Note that in some cases, you will need to use ADB to "push" the SU binary. You can can find the commands in my 701 unsecured boot.img thread here;
http://forum.xda-developers.com/showthread.php?t=1934056 Just don't use "my" boot.image as it's for the 701. Use the one in Vorbeth's thread.

[Q] 4.0.3 to 4.2 Upgrade Clarification

So I've been running the stock 4.0.3 Android on my TF300T for a very long time. at one point Idownloaded the asus provided unlocking tool, unlocked the device and installed CWM 5.5 and IIRC rooted the device in prep to run a custom ROM. I never got around to doing this but now I am ready to get this thing updated to the latest firmware ASUS provides ( V10.6.1.15.3)
There seems to be a mess of issues with the 4.2 bootloaders and such. So being a complete newbie to the world of Android I want to make sure I do not brick my TF300T or ruin it in any way.
As I understand... I can simply download the firmware. Unzip the .zip file to my SD card, boot into the currently installed CWM, install the new 4.2 update and all I will need to do in install an updated recovery for 4.2 afterwards correct?
EDIT: My plan is to use This guide >> http://forum.xda-developers.com/showthread.php?t=2187982 << I just want clarification that I can update to the TeamWin recovery after installing 4.2

Make sure you look into nvflash before you go updating to later firmwares because once you leave ICS you'll lose the option. Im not sure how many people here have access to nvflash because they brought their tf300t with JB pre-installed and dont have the chance to use nvflash as the exploit used is patched. But i was lucky and and took advantage of it while i was still on ICS, i would have bricked my tf300t 10 times over if it wernt for nvflash.
It makes your tf300t unbrickable, and lets you flash back to 4.0.1 bootloader if you have issues with 4.2:good:
And to answer your question yes you can update the 4.2 version of twrp AFTER the update with fastboot

New User with unlocked device looking for help

I recently bought a TF300t second hand and I really need some help! Some years back I was playing around with custom roms on Android devices but im very out of touch.
I would like to install one of the more recent roms on this device. Any suggestion here appreciated.
The device has already been rooted and has TWRP v2.6.3.1 installed. I understand that I need to upgrade this to 2.8. to install the latest roms but im having issues doing that. For a start im unsure how to find out if I have the latest Bootloader 4.2
I really dont want to brick this device!
I tried using ADB to update TWRP but the usb connection never seemed to find my device in the right mode.
The device is currently running Android 4.2.1
Custom ROM CROMi-Xenogenesis 5.4 - 10.6.127.5 WW ODEX.
Any help and advice really appreciated )

Android 4.2.1 is newest official.
10.6..... is bootloader version - newest there is.
flashing recovery and/or ROM will not overwrite bootloader - it stays the same.
You can go to twrp official website and get 2.8.0.1-4.2 blob to flash (unless your target rom states different version needed - see 1st post of yout target thread) - I got it from there - flashed KatKiss using it.
ADB - when android is running.
fastboot - on bootloader screen (booted with voldown+power - RCK / android / wipe data icons) - used to flash twrp blob

Ok got it all fixed now. Thanks!

So, not to hijack, but I'm actually in a similar boat. I'm currently rooted and unlocked on 4.1.1 TWRP 2.3.3.0 and am looking to flash the new 5.0 Rom.
Does anyone have a handy guide on what I should do? Do I just need to flash a 4.4 compatible TWRP version, then flash the ROM? Would like to avoid bricking my tablet.

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 ...
Thx Josh

Asus Transformer tf101 - Trying to install a Custom ROM

Hi,
Hardware: Original ASUS Transformer tf101
OS: Latest official ROM / update (Android 4.0.3)
Trying to make this thing usable again, which it really isn't in its current state.
It's been incredibly frustrating and confusing even getting this far (mostly because being an absolut noob (somewhat experienced Linux Admin, but no idea about Android, ROMs and Rooting) and also because the tf101 is obviously antiquated), but somehow I managed to both root the device (or at least the Root Checker App tells me so) and install a custom recovery (CWM) - but now I'm stuck because CWM won't let me mount anything containing the ROM I want to install (KatKiss 6.0, seems to be the newest available; not great, but better than 4).
So I tried installing TWRP instead of CWM - but I really don't know how. There are several ROM utilities that should be able to do this, but the only one that has been working so far was ROM Manager, which I used to install the currently active CWM. The TWRP App keeps telling me that it can't find the recovery partition, which I'm guessing is happening because it's looking for the original recovery and not CWM?
