[Q] how to get fastboot mode back on the tablet - Asus Transformer TF700

What I have done so far, in order:
Installed the OTA JB upgrade on my 100% stock unrooted tablet.
Installed and configured ADB.
Downgraded to the .30 firmware.
Rooted my device (confirmed working).
So right now I have rooted ICS, but I can't choose the fastboot option anymore when I boot using the volume down+power combination. I only have the option to boot the device normally or wipe data.
How can I get fastboot back on my device? ADB is still working normally.
It's probably a simple solution I'm missing but I've been trying to get CM10 installed for about 2 hours now just trying to work my way through the steps one at a time and right now I'm a bit lost.
Thanks in advance for the help.

I have been on JB for awhile, so if my memory served me right, for ICS, you need to unlock your device to get to fastboot? On JB, you could get to fastboot without unlocked. Correct me if I'm wrong ppl.

That's correct. You need to unlock if you want fastboot on ICS. If you upgrade to JB, you can keep your root and have fastboot back.
Also, you need to be unlocked regardless if you want to install a custom ROM like CM10 or any custom recoveries. Even if you upgrade to JB and get fastboot back, it will not flash if you're not unlocked.

I forgot to mention that I already used an unlock tool and it says this device is unlocked during boot. I'm on my phone right now so if someone could provide me with a link with more information about this unlocking I would be very appreciative.

That's the app I already tried, but the fastboot option is still missing.

[Q] What is the best option for my situation?

So I have a ns4g that I attempted to root but got hung up and am now stuck with a unlocked bootloader but no super user. So as I see it I have 3 options (if you see others PLEASE TELL ME)
1. somehow get my bootloader locked again and go back to stock (unroot)
2. keep unlocked bootloader and eventually accept ics ota (will this be ok or will having an unlocked bootloader much things up with the ota?)
3. figure out a way to finish the root process I'm sort of in the middle of (aka get super user)
If it matters I am running 2.3.7 and using a macbook running 10.7.2
What would you guys suggest?

flash a custom recovery(cwm or twrp) via fastboot, then flash a custom rom(and gapps). thats all you need. all the custom roms out there have root. you dont have to flash superuser.
How do I flash cwm? I think when I did this before I had the wrong version as it didn't allow for me to mount after I unlocked the bootloader
Use http://forum.xda-developers.com/showthread.php?t=1250583 to root! It will recognize that your bootloader is already unlocked and skips to flashing CMW and giving you root! There's a youtube video showing it in action if you get stuck by qbking!
Will this work with osx?

heres the latest version of cwm recovery for the nexus s(not ns4G) http://download.clockworkmod.com/recoveries/recovery-clockwork-5.0.2.0-crespo.img
heres where all the cwm recoveries can be found, including the ns4g http://clockworkmod.com/rommanager
Ok, now how do I get that img on my phone?
The cwm for ns4g that I just downloaded that is
I'm fairly content just waiting for the google ics ota... when that comes will it mess my phone up because of my unlocked bootloader?
or even better can someone write me instructions to lock my bootloader?
I found this forum http://forum.xda-developers.com/showthread.php?t=875630
But obviously there are steps before this to have the terminal put these commands towards the phone.

look at part 3 http://forum.xda-developers.com/showthread.php?t=1007782
only you dont need superuser, any custom rom has root.
Ok, I think I just want to relock my phone and wait for the ota...
I've tried just going into terminal and typing "fastboot oem lock" and it says that the command is not found... what did I do wrong?
You don't need to lock bootoader to get ota.
I've read before that accepting an ota with an unlocked bootloader will brick your phone... Can anyone else confirm that it's ok to accept the eventual ota with an unlocked bootloader?

HELP! Messed up with HTC Vivid

So as some of you may know, the vivid was recently unlocked. Being comfortable with root and custom roms from my nexus one, I unlocked the bootloader and rooted it...
I then wanted to install a ROM that many were reporting to work well with the ATT vivid... however I did something wrong.
I first went here- http://forum.xda-developers.com/showthread.php?t=1365853 which says you need to install the kernel here- http://forum.xda-developers.com/showthread.php?t=1359656
However I guess I have no recovery? If I click on recovery in bootloader it just shows a phone with some arrows... and if I open ADB on my computer it just scrolls through stuff quickly then closes. Am I screwed? I can get to my bootloader at least... any help would be much appreciated.
If I could somehow flash the stock kernel back I'm sure it would work, as the stock kernel source is available at htcdev However I can't figure out how to get adb to let me actually enter commands while in the bootloader.
Solved it!
I pushed the recovery using fastboot on the computer and was able to flash the ROM. Yay!
Ok so how does your rom work for you? is it better than stock? Oh and of course what rom was it?

Recommendations on OTA (ATT 4.0.3/4.0/1.73)

Hey all,
I rooted my HOX (1.73, 4.0.3) with the kpenn ne-Click a few days after I got it for the Tether and to de-bloat. Since then I haven't read anything on the One X till I heard Jelly Bean coming along. Anyhoo my question is what the upside of getting the new OTA (4.0.4) would be and how I would go about it if I wanted to (I've never updated before and ATT has stopped asking me to update, also I get nothing when I try to check for an update).
I've been reading around and it seems like most people are on to 1.85 and are flashing 4.1/2.2. My primary uses of my phone are for the media applications/web browsing and I haven't noticed any real drop in performance but I have heard the new updates have sped up the HOX considerably which is something I'm always interested in.
Thanks!
DON'T flash any OTA you will lose your root and will lose your ability to re root because there is no boot loader unlock for the new base. If you want to update and flash a new ROM and want to stick to sense, look at clean rom or xi40. Both are updated on the new base and are heaps and bounds better than the original ATT software :thumbup:

i one-clicked unrooted my phone earlier and freaked out (and the new updates didn't work out on my phone anyway). i ended up getting kpenn's one click again and putting SU back into my phone. Do you have any links that can take me on a step by step process of unlocking my phone and flashing those roms on it? I just love being able to control my phone and pushing it to its absolute limits.
Sigh. I followed the tutorial but I made a few mistakes...
1) I unlocked my phone way earlier than I should have so I wiped everything before I could make a back-up..
2) Re-locked accordingly to see if I could keep updating. I did manage to get to 1.85 like the tutorial said but.....
3) Since I didn't have a custom recovery I wasn't sure how to proceed. I couldn't get the root to flash so I tried using the 1-click 1.85 root since my phone was running 1.85.
....This ended up updating to 2.2 so now I have an unlocked HOX 2.2/4.0.4. With all the bloat.
Dumb dumb dumb. Ugh.

it's UNLOCKED?
you're lucky then.
just push a recovery like twrp then push root. Then you can debloat.
Yep, it's still unlocked. That was around the 4-7th reset I did (I messed up a lot). Do you have a link that shows me how to do that? I'm actually not as bummed about going to 2.2 since it runs so much faster than 1.73 did.

make sure you have your unlock token and then go to http://www.htcdev.com/bootloader/unlock-instructions/page-4/

after that look at this thread to install twrp http://forum.xda-developers.com/showthread.php?t=1777773
then this one to re-root
http://forum.xda-developers.com/showthread.php?t=1673935
I notice one of the links is for 1.85. Does that mean that I'll go from 2.2 back to 1.85? I just wanted to make sure since my impression from the forums is that there is no 2.2 root yet unless it was flashed.

no those pages just tell you how to manually install root and recovery.
your bootloader is still unlockable
unlock it
then install a recovery
then install root via that recovery
Ahh, thanks a bunch man.
Sorry if this is repetitive....
So I've checked my phone and currently it states that it is
"Re-locked"
I downloaded a recovery so it's currently on my phone. Furthermore I all ready had a copy of SU sitting in my phone's download folder.
Does this mean that I'm going to...
- Unlock bootloader (that is currently relocked) and have everything erased again.
- Reboot from recovery (of the evita 2.2.img I just downloaded with TWRP)
- Then flash the SU root I all ready have on my phone?

yeah unlock the boot loader. set up the phone again
then install the recovery then root.
to make your unlock stick, turn off fastboot in power options, then power down phone completely then restart it to the bootloader.
Hmm, so my phone is definitely unlocked now. I installed the recovery and I manually flashedthe new SuperSU in that link you posted for me. As far as I can tell nothing is happening.
Note: It says that it installs the recovery but there is no reboot that occurs. I've done this both with the android app and manually and nothing is happening.
I don't see SuperSU and rootchecker is confirming that my phone isn't rooted yet.
so you reboot to recovery, choose the superSU package to install then what happens?
I know this works I've done it quite a few times myself.
Presently I installed the latest img file with TWRP with the app. There is not reboot that occurs (unless I'm suppose to reboot on my own?). If that's the case then I've been a total idiot.
I've just been installing the openrecovery and then I press "Flash Roms" to flash the supersu. I get a little notification that says "Preparing to Flash" and then nada.
After you install twrp recovery you reboot. Then you boot to recovery and flash the super su zip manually
Wooh! I got it to work! Thank you so much!

Does this also mean that I can flash any ROMs I want on my phone now?
Yes. But you will have to flash kernels aka boot.img separately using fast boot.

[Q] thinking of installing a custom rom

i was thinking of unlocking my device and changing the rom.. however, ive permanently bricked this tablet for and had to have it repaired at a high cost, so im cautious.. i believe i fell victim to the having the twrp and resetting via the bootloader problem... how do i avoid this, how do i prevent this from happening again? i cant use nvflash, and is there any way of changing this annoying bootloader?

If using the wrong version of custom recovery vs bootloader can brick your device. The best way to approache this is, first upgrade your device to the latest JB .25, then unlock your device, then use fastboot to push your latest twrp recovery (2.3.3.0), then flash custom rom. Pretty much straiht forward without risk.

do i still need twrp installed or do i use fastboot for that?.. also i had to downgrade to 9.4.5.30 to root it first, should i need some kind of root protection before upgrading back to JB?

You don't need to root if you're unlocked because all custom roms are pre-rooted. Maybe this will be clearer;
Let pretend you're on JB, if you are on ICS, just use OTA upgrade to JB.
1. use Asus unlock tool to unlock (the tool will work with ICS or JB and very safe to use)
2. Use fastboot to push TWRPcustom recovery to your device
3. Boot into TWRP to flash custom rom (now have custom rom and rooted).
Done.

Yes, "fastboot flash recovery ... " installs a recovery.
I rooted mine when I had ICS and used OTA rootkeeper to OTA to JB to keep root. Unlocked it then used Goomananger (required root) app from the market to install TWRP. I like goomanager as you dont need to hook it up to your pc and was pretty easy. If you're already rooted I would go this route to install custom recovery.

I was just as hesitant as you are. Took the leap yesterday and I am VERY happy I did. CROMI turns this baby into a whole new experience!
Just follow the instructions in this thread:

Read it, follow all the links, read it again and when you feel you really understand the process, follow it step by step.
The whole process turned out to be a breeze - especially compared to the trepidation I had about this

Best rom is CleanRom version 3.2.1.
ok.. well it seems i have twrp installed just fine now, used the fastboot method... im going to try cleanrom a bit, and try out the ubuntu LXDE rom as well, ill try cleanrom first
it looks as if everything was successful, and i made it past the stage that caused a brick before, so i would say im in the clear now, tried clean rom, pretty cool you can choose your stock launcher but i really want to experiment with ubuntu on it as well with a mouse and keyboard, see if i can replace my netbook with this

[RESOLVED] Bootloader Unlocked, rooted, OTA update failing?

Hey all,
Ok, so I rooted my Razr HD, unlocked the boot loader, and now would like to take the latest OTA update. It is failing right now. I tried a factory reset before doing it, and saved root with voodoo and all that. I am assuming though, that it is failing because the recovery is not stock? It's TWRP.
What do I need to do to get the damned OTA update installed, and then have the custom recovery with root intact?
Thanks!

Resolved:
Used clockwork mod instead, downloaded stock image, flashed using RSD Lite 6.1.4.

You can go the hard route and re-load the stock recovery, re-load all of the stock apps, and take the OTA. You can also fastboot to the latest OTA and just re-root. It's easy to re-root with an unlocked BL, you just need to flash SU in recovery. The easiest option is to find a stock ROM on here and just flash it. I believe there are a couple in dev section. Also, there is one on Batakang that's based off of the latest DST ROM.

as long as you didnt delete or freeze any stock apps put stock recovery back on using this tool. http://www.mediafire.com/download/tt7cwwua49n24uv/Razr_HD_Recovery_Flasher_V7.rar then take the update. make a note of your baseband before you start because the update is going to fail at the end even if it installs. the bb will let you know if you got all you could or if there are issues. afterwards, restore root and use the tool to put cwm or twrp back on.
Hi guys,
So i had my phone rooted with an unlocked bootloader running CM for quite some time. I decided yesterday to go back to stock (factory reset via matts utility). Its been hitting me with an OTA update since then, and i kept hitting install later...install later....
and today i accidentally hit install now. So it tried to do it via CWM recovery, and obviously failed. and when it fails, no matter what i do, it reboots back to the system (which is good), but then immediately tries to run the update again.
Is there any way for me to get this to stop happening? I turned off my phone in case i have to do something via fastboot (save the battery). but can i maybe flash the stock recovery through the utility? would that do it?
Thanks for any help!

Just compare the stock & mod9 xmls, no secrets.
Just be warned that downgrading to 4.0.4 will NOT allow you to unlock the bootloader.
