[Q] Root method

I have an ASUS TF300T running stock 4.2.1 build JOP400D_epad-10.6.1.27.5-20130902. I'd really like to, at a minimum, root this thing so I can boost it up a little bit. And at the most, install another ROM like CM 11.
I've rooted other machines (Droid Incredible, and my current Droid Razr) so I am not a novice by far. But after searching around I am finding that I can't really determine the 'best' method for rooting the TF300T. By best I mean - easiest and safest. With this in mind, can someone suggest the best method (and URL) for rooting the TF300T? And if I want to go so far as putting CM 11 on it (like I did for my phone) can Safestrap be run on this tablet? Any caveats?
Thanks in advance!
P.S. I might mention I use a Mac, so if whatever root method can run on a Mac that would be great. Otherwise if the method can work under a Win 7 VM (VirtualBox) that would be fine too.

I don't know about safestrap, but this is one of the pickiest tablets when it comes to ROMs: One mismatched bootloader, and it becomes an expensive paperweight.
There are several root methods in the General Forum if thats all you want to do.
For Customs ROMs, you will have to first unlock the bootloader, then update to the latest stock ROM, install the right TWRP, then pick the corresponding ROM. Never click wipe data in the bootloader menu.

Yeah, that's my worry, from what I read it seems this is a very 'picky' tablet - and I don't want to blow it up... so maybe I'll just start with rooting it. That way I can at least customize a few things, get rid of bloatware, etc. Hopefully that will help it a bit.

So what would you consider the 'easiest' and 'safest' of the root methods shown in the general forum? Any suggestions? Also, I assume the latest stock ROM is still the 4.2.1 build JOP400D_epad-10.6.1.27.5-20130902? I haven't got anything newer yet via System Update. That's why I was thinking of going to CM 11 like I did on my phone - to get Kit Kit. We'll probably never get it directly from ASUS....

Hmm, I'll give this a try. So is this what you used to get root on your TF300T? It looks like it works for a variety of different machines.
Does this only do root? Or also bootloader unlock so you can run other ROMS? Also, if for whatever reason I had to revert root and reinstall stock, will that work after rooting with this method?
Thanks!

This does ONLY root. Your bootloader is still unlocked, but if you reinstall stock, the root will be removed. If you do choose to unlock your bootloader, it can never be relocked and your warranty is forever void.

OK cool, I'll give it a shot. I'll first start with root and see if I can then optimize the tablet to run a little bit better (and get rid of the bloatware). Then later on I may consider unlocking the bootloader and trying another ROM - especially KitKat.

OK cmendonc2, I like having root, but I think I am about ready to unlock this baby and put on another ROM. I know the risks, and that my warranty will be voided - but I've had this a couple of years so it's not under warranty anyway.
So... I got the ASUS Bootloader unlocker program from the ASUS site; and I have what I believe is the latest TWRP. Is there a good place for instructions on how to unlock this thing and install a new ROM? I know it can be picky so I want to do it right and not brick it.
Also any suggestions on a good ROM? I was thinking CM 11, but I've also heard good things about OmniROM.
Thanks.

OK so you have bootloader 10.6.1.27.5. That's the latest version, so you don't have to worry about upgrading stock. This TWRP (http://www.androidfilehost.com/?fid=23329332407579270) is compatible with the bootloader. Download any 4.4.4 ROM from here: http://forum.xda-developers.com/transformer-tf300t/development. Then download the latest GAPPS from here: http://goo.gl/ZcwCW9.
After unlocking, extract the TWRP blob and put it on your SD card. type this into Terminal Emulator on your tablet:
Code:
su
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4
Then restart and go into TWRP. Wipe Data and cache, then install your new ROM and gapps.

Thanks, cmendonc2... I'll give this a shot tonight. I think KitKat will perform better on this tablet (I hope). I think I'll try OmniROM first.
BTW, I thought I read somewhere that there was one TWRP option (a specific Wipe option) that I was to NEVER use or I would brick the tablet. You know what that option is?

Thats the Bootloader option "Wipe Data". You see that when u press vol down and power to get the three icons. It is the icon on the far right. Selecting that will result in an expensive paperweight.

OK I got the TWRP but when I extract it there is no .blob file. So what am I missing? There doesn't seem to be much in this .zip file.... I guess to do it the terminal way (seems the easiest to me) I need the blob file. I've googled left and right but I can't find a TWRP 2.7.0.1 blob.
Or would this ROM Manager app work?
UPDATE: Never mind, I figured out how to flash recovery using Fastboot on my Mac! TWRP is now installed and working! Going to try flashing OmniRom and see how that goes. So I think the only question I have left is: When I am flashing a new ROM (i.e. over the old stock) what wipe options in TWRP should I use first? Obviously cache and Dalvik, but which other ones? System? Data? For this first flash I obviously want/need to start fresh.

Flashing problems

OK guys let me tell you about my issue's
I'm using TWRP 2.7.1.0 (Tried 2.7.0.2 no difference) S-off, Unlocked, latest firmware from Santods files. The phone works fine with Sense ROMS but for the life of me I can't flash a GPE ROM. They fail every time. Santod tried to help me out the best he could by having me replace the Boot.img from the ROM I was flashing thinking that I was on a secure Boot image (And I may be but I replaced it and they still won't flash). Mr. Jaydee82 also modified a ROM for me to try out (although I'm not sure exactly what he did to it) and it wouldn't Flash properly either. When I try to flash these ROMs it will appear to flash properly and then they will go to the bootscreen and just sit there and churn. Depending on the ROM some will time out and power down the device and some will just sit there forever until I do a virtual battery pull. I'm freaking desperate to find out what is going on with this device and I don't feel right bugging Santod so I decided to post this in hope of more ideas about what could possibly be going on with my device. Any and all help greatly appreciated!!!
Thanks!

I used Firewater I'm able to Flash all of the Sense ROM's not sure if they are considered AOSP. Give me an example of one and I'll try it. I'm not 100% sure if I took the OTA update before I Rooted and S-offed/unlocked the device but I think I did. I Flashed Santods Nobootimg firmware via ADB to be sure I was on the latest firmware. I know my radios were up to date before doing this but I wasn't sure about the FW so I flashed it. Flashed fine, didn't need to flush again, flashed fine first time.

I really appreciate your help. Santod and me went back and forth via PM a few times and JayDee modified his Rom for me and now you. IDK....I'm dumbfounded. If you think of anything let me know. I'll just stay on AOSP for now. Always liked Cyanogen's stuff anyway, just never even thought about them since their ROMS are not in the forums. They used to be for my various other phones. Never really though about them not being on XDA until we did this just now. Thanks again for you time and help!!!

Yeah cm11 is what I'm currently using, it recently had a speakerphone issue but its been fixed since 7/30. The only AOSP ROMs that have incorporated the fix are cm11, liquidsmooth & aokp. Here is the section for all the aosp ROMs they are universal so means 1 zip for all HTC One M8 variants.

About Root in 05Q

Hello guys!!!, Today I get the new OTA with the firmware 05Q and I install it. I see in the forum a version of 05Q rooted LINK HERE
I only want to ask if anyone know another way of get root actually or if I should wait until our amazing toolkits for 1+1 get updated.
Thanks i nadvance!!! :cyclops:

You can gain root following, This thread. If you already have a custom recovery install, might be easier to install the pre-rooted 05QA. I went the second route.
P.S. That toolkit will root 05QA, just does not have the new firmware to go back to stock.

I have a custom recovery installed ofc, if I install the pre-rooted 05Q I lost all my data and apps? Should I do a factory reset? Thanks for your fast answer mate!!

If you have custom recovery installed. Do a back up first. You should not have to wipe or lose anything.

Wait guys, all you need to do is flash SuperSU from your custom recovery. That's it, nothing more.

You said that flashing entire ROM would be easier, it isn't. All that's need to get root is to flash the SuperSU zip. He's already on 05Q so flashing the ROM zip is completely and utterly pointless. It's like telling someone who's run out of petrol to install a entirely new petrol tank that's full of petrol (when all that's actually needed is the fuel).
It doesn't matter what someone thinks might be the solution, if you're going to answer in the q&a section you need to give the best and easiest solution.

The thing is flashing update-supersu is not working... for me at least. I updated OTA.. After installation finished, rebooted to TWRP and tried to install update-supersuv2.37.zip...
It doesn't show any error, but when I reboot my phone there is no supersu installed ( actually there is one but it's greyed out with android icon and not showing up on application list )

Sorry guys for don´t answer your comments, I have been working out of my country for a couple of weeks.
I get root on 05Q with just flashing SuperSU 2.46 from recovery. Easy and fast, just that.
Anyway you have my thanks in your respective buttons.

New at nexus :P(questions)

I used to have sony devices so i new how to flash roms on such phones pretty well. Now i moved to nexus 5. I need somebody to help me install twrp recovery and a good kernel (i found elementalx) for lollipop. Also i got a question.. If i get bored or need the warranty in order to get back to full stock will i just have to flash the factory image with the instructions google give us? Also if i flash the custom recovery will i have to reflash the rom?(by unlocking bootloader do i lose my data?

No, as long as your Google account logged in is the same

Oneplus one downgrade 6.0.1 to 4.4.4

Hi, Is it possible to go back to 4.4.4 from 6.0.1?

i think its possible , with cm11s. just try it, and let us know ! dont forget to backup , just incase

its CM13 back to CM11. Which software should I use. Read a lot of topics but, which one is for my phone?

I think you'll have to download 44s firmware and install it before you proceed with the rom.

You can! There are multiple way to do it:
First of all, you have the option to dual boot your phone with 4.4.4 using multirom or EFIdroid (not sure about EFIdroid)
You can just flash the full 4.4.4 zip as secondary rom, however! you NEED to flash the 4.4.4 modem in order to make the proximity sensor to work.
You can also just flash 4.4.4 as main ROM without using multirom or EFIdroid, make sure you wipe all the partitions first, then flash the full rom.
There is also the QHS_Bulk way.
First restore your phone using the color.zip in this guide.
When on color os (the chinese 4.4.4) you can fastboot flash the cm11s rom over it (step 4 in the guide, but make sure you use the cm11s rom).
Have fun!

You can but you need to flash KitKat firmware for oneplus one, also you need to find a compatible recovery menu to flash the ROM and firmware. Be sure to keep a backup of anything goes wrong

try this https://forums.oneplus.net/threads/how-to-back-to-stock-repair-system.225170/#post-8737053 , it might help.

Thanks all for the replies. I am a complete noob at this.
So what do I need to do exactly. I know my mums phone still has 4.4.4. so it is possible.
I have backup everything now so not afraid to lose any data anymore.

1. unlock bootloader
2. install twrp
3. flash new rom

Possible, but stupid idea.

You can just flash stock COS from fastboot
Choose what you want, I suggest the glorious 44s

PS
That ROM was the most stable with KK back in the days, but on some devices it needs a custom kernel to fix ghost touches.

Follow this until you install twrp:

And download the signed flashable zip you want, and install it from twrp.

By the way I am in twrp but, when I try flashing CM11 it says:
could not find meta-inf/com/google/android/update-binary
How to install twrp?
Oneplus CS has flashed mine back to 5.0.1 android with CM13. If I flash back 44S Will the android version go back aswell?

Thanks all got it reflashed to Kitkat and done now. Was stuck at step 4,5 and 6 while I only need 7,8 and 9.
