I have a UK model Xoom, WiFi only. A while back I unlocked the bootloader and flashed the US system image on it.
I am trying to get a recovery image installed on this, but literally every recovery image I try seems to be incompatible. When booting into recovery I get the "!" in a triangle in the Android's belly image.
Flashing a recovery ROM is pretty simple stuff. Is there something I should know about the WiFi Xoom from the UK? Are the standard recovery images not compatible? Is there something stupid and simple I might have overlooked?
The issue will be the fact that you're on stock android and trying to boot a custom recovery image. You must either be rooted or have a custom ROM otherwise the system will wipe over the custom recovery and put back the system recovery, this is why you are getting the android with the exclamation mark in it.
You can also, once flashed a recovery image, is to boot immediately into recovery on the first boot after flashing the recovery image, thus not giving a chance for the system to overwrite the recovery

That makes a lot of sense. I guess in the past I've always rooted my devices a matter of course; I never considered that you had to root before installing a custom recovery.
Thanks for the help!

no worries bro
Hi,
Actually the problem there are two files which flash the stock recovery back. To remove them you need to root your device.
To use the custom recovery follow the idea of matt4321, just boot it right after flashing .
Good luck,

So. I'm sorry to say, but this phone has given the biggest headache. Here's the background:
I really only use this phone for entertainment and stuff. BUT I decided to root and unlock the bootloader, somehow or another the phone apparently lost root a few times (According to some users here) but never lost SuperUser or anything. I've never been able to flash a rom on this thing. Then a few weeks ago the phone just encountered an error of some sort and would only get to the ICS boot animation and loop over and over. I just gave up on it. Then one day I decided to play with it. I got it into fastboot and then into recovery, (Not CWM Recovery) and was able to get it all set up again. So I figured I'd give it one more shot. I downloaded CWM and downloaded recovery, and a custom rom. tried to flash through fastboot>recovery but it's still the stock recovery, not CWM recovery. So I factory resetted it etc and started from scratch. Now if I download CWM it WILL NOT download recovery. It gets about 99% of the way and tells me: "An error occurred while attempting to run privileged commands!" If I download it from a link I can't open the file....... Someone help I just want a good JellyBean Rom. :crying:
Edit: I've Googled as much as I could stand and still haven't come across anything entirely helpful. Please explain so I could understand. Pictures help if needed lol
Anyone?
You can't use clockworkmod app to flash recovery without root.
Get the fastboot image of cwm recovery ( not the app). Or twrp. Flash it with fastboot.
Boot directly into it and flash what you want. If you boot up a stock os it overwrites the custom recovery on boot.
clockworkmod app sucks IMHO and should never be used for anything period. Not fond of the recovery itself either.
Hey guys.
I just got a very nice condition used TF700T. I am trying to get recovery to install so I can flash a rom. I used the Transformer Toolkit to unlock it, which worked, it says device unlocked when booting.
But I absolutely cannot get it to Root, or flash recovery. If I try using debugfs root generic 2.3 it fails to write everything. If I try to flash any recovery with the toolkit it downloads and says flashing but just sits at about 25%, it boots my device into the screen that says usb fastboot mode with the three icons that say RCK Android and factory wipe. If I click the RCK it says rebooting and then goes to android mascot installing icon, but then the one with an X and error appears. What on earth am I doing wrong?
Is it the latest 4.2 update locking me out? Can I downgrade? I just can't get anything to root or flash recovery no matter what I do. I feel a little defeated being a long time member and 3 phone habitual rom flasher :crying:\
Any ideas what i'm missing?

What custom recovery are you installing? You may want to try with fastboot or adb method to flash your custom recovery which doesn't require rooted device, good luck....

Well I tried TWRP 2.7.1.1 I believe and also CWM , and Phil's custom touch CWM that all three are options to flash with the all in one ADB Toolkit app via USB from windows (http://forum.xda-developers.com/showthread.php?t=2094746)
How do I do the Fastboot method? I read about that, but have no idea how the process goes. I'm ok with skipping root and going straight to recovery and a rom because I can just flash superuser after if the rom isn't rooted already.

I wanted to try an app I used to get twrp onto my LG G2 for the first time called "flashify" that worked like a charm. I just installed the app, downloaded the twrp file and flashed it then it reboots to recovery, but it requires root as far as I know. Does unlocking the boot loader allow things like this?

Unlocked bootloader is allowed you to install the custom recovery so you can install the custom ROM, I believed..... You can check this guide out to see if you can setup your fastboot/adb. It is very easy to follow for the beginners, good luck....:fingers-crossed:

Once you unlocked the bootloader you can flash a custom recovery and after that - the sky's the limit.
Flashify works great, and it is a wonderful tool as long as you're able to boot into Android.
My problem with Flashify and Goomanager and TwrpManger is that it saves users from setting up a proper ADB/fastboot connection from PC to tablet.
As long as you can boot Android, these apps are great. But what if you can't? Once the tablet doesn't boot it's so much harder (and often too late) to get the correct drivers installed for ADB and fastboot.
So if you flash your recovery with any of those apps still make sure you have access with ADB and fastboot from your PC.
You will regret it if you don't - I (almost) guarantee it.
That's an excellent point. Thanks. I did actually get the Fastboot method to work. The problem was that I kept clicking into RCK recovery when I ws supposed to just leave it on that screen to push twrp instead. I got recover and just got done doing a backup. I'm about the flash my first rom (http://forum.xda-developers.com/showthread.php?t=2672751). Do we need to do factory reset / wipe data/system etc? The instructions on the ROM post say to just flash it from twrp so I'm guessing it has a built in wipe feature during install?

The instructions in the OP actually say that you have to do a full wipe (Factory Wipe) in TWRP coming from a different rom base. Which would be you unless you had a version of CROMBi-KK installed prior to this.
It's the default selection under the Wipe menu in TWRP. Just do that and then flash the rom and your ok.
Do not use the Factory Reset option from Settings or the Wipe Data option from the BL menu! Do this in TWRP only!
Cool thanks. I figured so because that's the norm with roms on all my phones. Thanks a lot for the help guys. So happy to be get KK running on my new toy!
Just wanted to update. KK 4.4.3 rom flashed and booted in. It's much nicer. The stock was a little laggy, and KK breathed a lot of new life into my ancient single core 1.0 ghz Galaxy S that I use as a music player so I figured it would help make the tab real nice and snappy too. Gotta go now, much fun to be had!!
Hey guys,
I'm having some trouble with flashing a new ROM and now I've soft-bricked my device.
I was trying to flash from CROMi to CM11 so I wiped data, cache, dalvik using TWRP. But when i tried to flash CM11 M9, i would get the "failed" error. I tried flashing other ROMs but same result - "FAILED".
So I thought maybe it was the recovery. I downloaded a CWM recovery (in .zip) and tried to flash it. FAILED!
I tried to restore my device using the "Recover /Downgrade from Jelly Bean to ICS/Clean Factory Restore with custom recovery" method from this post. Since it is basically flashing the stock ROM, naturally it fails.
Now I'm out of ideas. How can I save my tablet?
Thanks for your help guys!
PS: I'm trying to install CMW via fastboot. When I press power + vol down, I get to the screen with "RCK, Android, Data Wipe"; I dont see the USB icon. How do i boot into fastboot?
You are in fastboot mode when you see the three icons. Read the tiny script.
Except for CM11 M9 you did not give us anything to work with.
Give us the version numbers of:
- CROMi-X you were running
- your bootloader
- your recovery
My best guess is you are trying to flash something with an incompatible recovery, but that's just a wild guess.....
And stop flashing willy nilly until you know what's going on. You can brick this tablet if you try hard enough, you know....

Hey bern,
Thanks for the reply.
My tablet got really slow so I decided to flash CM 11 M9, which is what I use on my Note 3.
I'm running TWRP 2.6.1.0. Not sure which CROMi I was running because I can't boot into Android. I did a data wipe prior to (attempting to) flashing CM11 and now it boots straight to recovery.
I read that TWRP is not compatible with CM11 and that I should flash CWM. But TWRP fails when I try to flash anything so I'm thinking I should attempt ADB sodeload or terminal command and load that way?
Thanks again
Edit: I downloaded CM11 M9 for tf700. I also tried various nightlies in case my original download was corrupt. It ends in failure

Hi berndblb!
I'm also having this problem and I see that you're quite active in the TF700 forum that you could help me out. I wouldnt say I'm an expert but I have tinkered with phones (mostly Samsung and Nexus devices) in the past so I am familiar with ADB, terminal commands, flashing ROMs, etc.
I'm running TWRP 2.6.1. I was running CROMi-X (not sure which version) and wanted to flash OmniROM. However, TWRP would show "error flashing zip" and "failed" in red. I tried flashing a few other zips including TWRP 2.7.1.1 and CWM (I readTWRP is not compatible with some ROMs) and I would still get the error and "failed".
So now, I can't boot into the OS to flash a recovery via fastboot or via CWM Rom Manager, nor can I flash anything in TWRP. I also attempted to flash TWRP 2.7.1.1 via terminal command
HTML:
dd if=/sdcard/twrp.blob of=/dev/block/mmcblk0p4[HTML]. I loads but it doesnt install when i restart my device.
What do you think I should try next? I'm getting pretty desperate at this point. Is my device bricked-bricked or can i salvage it?
Thanks!

Right now the most important thing is the bootloader version ....
On the bootloader screen upper left there is a bootloader version in really small print ...
This is what we need to know ...

Exactly.
I also would like to know how you performed the wipe you mentioned. The tablet booting only and straight to recovery would indicate that you used 'Wipe Data' from the bootloader???
Also, do not use ROM Manager. It does not work well with the Transformers and can cause a lot of problems.
I have a feeling another user is going to benefit from your excellent unbrick guide, Josh...
Aren't you glad you wrote it?? [emoji12]

No boot to recovery ?
No bootloader ?
No nvflash blob backups ?
If that is the case then you are not looking good ...
There is no way out of this one ...

Do you have adb access when it boots to the Asus splash screen?
Hi,
I wanted to flash the just released lollipop image so I unlocked my phone and updated TWRP from 2.8.0.1 to 2.8.1.0. Then I started Recovery and it was doing some werid thing in a list (was too fast), then rebooted. Recovery came up again (only the image of TWRP) and a restart again. Since then always when I try to go into recovery the starting image will show up, after 2-3 secs it gets black for half a second, then the image will show up again. This is a permanent loop. I flashed back to the old recovery but nnothing, still the same (and this one worked before!).
Hopefully someone of you knows whats wrong.
Thanks,
S3cret
reflash twrp recovery. but to correct you on your mistake before you do it, factory imgs are not flashable via any recovery, you can only flash them via fastboot.
I reflashed recovery several times now. I just thought being on the latest recovery version would be good. I know how to flash the lollipop image via fastboot, but I still need recovery for root.
I locked and unlocked the bootloader again and the same happened. Recovery started, doing some weird things and then the loop again.
Edit: Ok, I fixed it, somehow, I dont rly know how...
TWRP only starts after flashing it on my device. After a reboot, it doesn't work.

Yup, dead Android with red warning triangle appears...
My stock recovery is broken after fastbooting the latest 5 image. Shows a red triangle above the laying down android.
How are we supposed to fix this?
Moreover, I've just reflashed the entire rom, and can't access the stock recovery. But the stock recovery seems to work beacause I can to factory reset via the settings menu, backup and restore.... Maybe it is the new security policy from google, to avoid that a thief make a factory reset directly from the recovery ?
So we can't navigate in the stock recovery anymore ?
Highway 55 said:
After fastboot flashing the .img files you need to (WITHOUT REBOOTING) flash custom recovery, TWRP etc... After that from the bootloader reboot into TWRP or whatever. When your in the custom recovery you need to adb push a permissive stock kernel or custom kernel as well as suspersu.zip. Again, without rebooting into the system, flash the kernel first then supersu. Now you can reboot into the system. ?

Yes I think it does have to do with the new selinux security stuff. I don't know the specifics. Maybe you want to refer to this thread. http://forum.xda-developers.com/showthread.php?p=56538538 @rootSU knows far more than I do. [emoji6]

It is exactly as he said in the post you linked.
Flash TWRP recovery and immidiately after run auto root. Then TWRP recovery will survive system boots.
Hello guys. I think I have a very particular problem since Noone on the forum has mentioned/solved this problem before. Basically I have my old tablet replaced with b01 battery. It came with lollipop os 2.2.2 (I think) I rooted it like I did before with flammable y01 with twrp so no problem on that hand.
Now I'm selling it and I need to get it back to the stock os with stock recovery. But as is seems this turns into something impossible :
Every time I try to flash stock image the red triangle appears when I try to boot into recovery no matter what I do :tried to flash Via fastboot many times, tried different fastboot drivers (one from Nvidia, another one from Google) tried to mess with flashing sequence - staging - reboot - boot.img - recovery.img - reboot - system. Img, userdata.img - dtb - oem lock - reboot and still the red triangle with broken Android. Tried flashing it from 2 different notebooks, with clean win 7 and clean installation of Nvidia drivers. Still no luck, as soon as I finish flashing staging and booting into recovery with volume keys I always get the red triangle. However when I try to install a twrp it boots into recovery instantly. I even tried erasing all partitions before flashing :fastboot erase recovery, erase boot system ecc without result, tried even to flash staging, boot and recovery partitions from older os versions keeping the system and userdata from 2.2.2 and no luck.. Can please some one explain why the original recovery doesn't want to stick?? The cwm recovery like twrp work like charm whenever I try to flash them... So it's not up to hardware.. Please help me guys
Maybe have to relock the bootloader. Why can't you sell it with a custom recovery and rom?

Stock recovery doesn't really have a user interface like TWRP or CWM so I wouldn't worry about the red triangle. Is there any reason you can't sell it with the custom recovery?
You can easily lock and unlock the bootloader so what's the issue with trying that? And if you want it to be 100% retail stock, the bootloader would be locked.
You can also try to re download the stock restore files again and try again. I don't recall the stock recovery giving you any options anyways so that screen you're getting should be fine.
