Cant install new recovery

Hi, ive been trying to S-off and root my HTC sensation using this guide
http://forum.xda-developers.com/showthread.php?t=1870233
ive managed to get up to step 2, but unable to flash a new recovery using instructions in this guide and also whilst trying kgs utility…. Im pulling my hair out tbh been at it for hours…
so basically, I unlocked my phone, then have got s-off..but now cant get new recovery to get rooting.
when I use the utility in theafore mentioned guide. It either cant find device or just hangs. When I use the kgs utility, it looks promising until I get the message the system cannot find the bacth label specified - dl_4ext_found
any ideas?

try this
boot your device into bootloader
connect your device into pc via usb(it should say fastboot usb)
now in your pc place the recovery.img in the folder where you have adb and fastboot files
open a command window in that folder and do this command
fastboot flash recovery recovery.img

hi rzr86, thanks for the help. tried what you said, but it tells me remote not allowed. any ideas?

hmm ok,
do you have htc drivers installed?
also check if you are using 2.0 usb ports
enable also usb debugging mode
edit:i just inform you also that the recovery can be renamed as recovery.img
i mean when you perform the command do it like this
fastboot flash recovery <the name of recovery>

that's why you couldn't perform the command
if i remember well after S-OFF an unlocked bootloader goes again locked
but there was no need to unlock it again
you could use an eng hboot(juopunutbear) which is unlocked
nevermind
flash this zip from recovery now
http://download.chainfire.eu/310/SuperSU/UPDATE-SuperSU-v1.04.zip
it will give you root

hi and thanks..
So i should capy this to my SD card, then what? sorry for the noob questions.

hmm, i think i must be doing this wrong guys. it thought I flashed the recoevery ok, but then when i hit powerdown on the recovery option, it goes to an HTC logo for a while, then i see my vodafone logo etc and then have a clean install of the orginal rom i guess.
Where am i going wrong?
Many thanks

[Q] AT&T HTC One X Bricked and need advice

Hi,
I have an AT&T HTC One X with no OS. I wiped it when I was trying to flash a custom ROM.
I only have access to bootloader and TWRP. Fastboot is working fine but TWRP is not. It does
mount properly, and adb sideload fails as well. I am using a Windows 7 PC and used a USB 2.0 port.
I installed some HTC Drivers from here:
http://forum.xda-developers.com/showthread.php?t=2217396
but it still says "device drivers failed to install" when I boot into recovery.
When I try to mount, it does not let me mount the sdcard. I see an E: drive on my
PC but it is inaccessible.
I have S-On, my bootloader is unlocked, and I have hboot version 2.14 if that info helps.
Does anybody have any suggestions as to what I can try next?

First thing you need to do is clear your post up a bit. You said you have access to TWRP but it isn't working, can you elaborate on that please?
You also said that it does mount, but then you said later it doesn't mount, which is it?
Have you performed a factory reset from the bootloader at any point?
Exactly which ROM(s) did you try to install? I need the exact filename(s) please.
Did you remember to flash the boot.img with fastboot after flashing the ROM?
Do you have a TWRP backup on your phone?
Please answer all questions with as much relevant detail as possible, that'll aid me to help you properly.

I helped him over teamviewer so I can clarify the situation. He can't mount in TWRP, it must of been a typo. It seems he cleared everything when he was trying to wipe to flash a rom. I believe it was ViperXL. He has no backup and sideload does not work as well. Hopefully that will clear things up a little bit more. I installed some newer HTC Drivers since the ones he had were old. The only thing that works seems to be fastboot at this point.

Sorry it was a Typo, I was not able to mount at all. The error said "unable to mount /sdcard"
Yes I have tried performing a factory reset from bootloader but the phone restarts and comes back to TWRP and then same thing.
I tried installing the ViperXL ROM but was not successful.
I was not able to flash the ROM and I tried to fix that but meanwhile looks like I wiped all what I had on my Phone, so no but I did try to flash a new boot.img after and it didnt work.
I dont think I have any TWRP backup on my phone, even though I tried flashing new TWRP but all failed.

Ok first thing, don't ever perform a factory reset from the bootloader because it corrupts your sd card. That's why you're experiencing problems now. You need to wipe the sd card/internal storage using TWRP 2.6 to make it usable again. If you don't currently have TWRP 2.6 installed you'll need to do that. Download it from here. Put the file in your fastboot folder. Connect phone in fastboot mode, open command prompt from within fastboot folder, issue the following commands:
Code:
fastboot flash recovery "filename.img"
(the exact filename, minus the talking marks)
Code:
fastboot erase cache
Code:
fastboot reboot-bootloader
Now you should be able to mount your sd card using TWRP and copy a ROM across to flash.

Rebooted again and it displayed TWRP 2.6.3.0

Did you wipe the sd card/internal storage like I said before trying to mount it?

That's really screwy. I think you should try installing recovery again. What happens when you boot the phone normally?

Ok good news, something happened, I tried all the steps again carefully and now I see TWRP 2.6.0.0 on boot and I am able to mount the sdcard and my computer now recognises the phone and I can manually copy files on to it.
Now in order to not mess it up anymore, should I just copy ViperXL ROM or should I use ADB sideload?

Either one should be fine. If you have S-ON and the phone gets stuck on the HTC screen, you have to flash the boot.img. here's how to do it.
1. On your PC in the ViperXL.zip, take out the boot.img and put it in the directory where you have the adb and fastboot files.
2. Boot into fastboot.
3.Open cmd. Change the directory to the folder where you have those files.
4.type "fastboot flash boot boot.img"
5. Reboot the phone.
The phone should boot.

Definitely install through TWRP. You shouldn't need to flash a boot.img because Viper uses an aroma installer which does that for you. But, if for some reason it doesn't work just flash the boot.img via fastboot.

No I did not check the MD5, yes I'm on TWRP 2.6.0.0 and the errors it gives are as follows:

Always check the md5. It's possibly corrupt.

Yup redownloaded the file, checked/compared MD5, copied it back to the phone, removed the previous bad copy, flashed ROM successfully..., as per the message but system reboots to recovery.. is that expected?
And I still see both the TWRP's 2.6.3.0 and 2.6.0.0 the phone needs couple reboots in order to get to TWRP 2.6.0.0 but automatic reboot is in TWRP 2.6.3.0 whats the deal here?

I have no idea why your recovery is acting like that. Hopefully someone else can chime in on that.

[Q] Can't boot into TWRP after updating to 4.4.3

Before I updated to 4.4.3 I was able to boot into TWRP by using the fastboot commands:
fastboot boot twrp.img
It would automatically reboot the phone into TWRP where I could flash SuperSU yet retain stock recovery.
Now when I attempt to do the very same thing on 4.4.3 I get:
downloading 'boot.img'...
OKAY [ 1.320s]
booting...
OKAY [ 0.402s]
finished. total time: 1.722s
The phone reboots but instead of rebooting into TWRP it just reboots the entire system.
I'm using stock everything, S-off and Unlocked.
Any help is appreciated.

Why not just flash that recovery and then boot to it from the menu? Or you use flashify from within the Rom and change recoveries on the fly?

I know you got this resolved, but for future reference, your command should be: fastboot flash recovery nameofrecovery.img
You flashed the recovery as if it were a boot.img, which it's not.

I wanted to follow up on this. I've used his idea in the past on another htc device. I'd "fastboot boot <recovery>.img" and I could flash whole ROMs without touching the existing recovery. As soon as you reboot the old recovery is still there. His command wasn't an incorrect syntax for flashing a boot.img it was temporarily booting into a recovery. Is there any reason this wouldn't work nowadays?

Yeah I know that was possible in the past, to flash a rom using a recovery one time, without overwriting the current one.
As I've never seen any real need or purpose to doing that, I've never done it that way.
I do know that the other command is what should be used to actually overwrite and flash a new recovery for further use.
So I can't really answer as to whether that method still works or not.
Didn't sound like it did for him though.

[Q] Flashed the LPX13D image and now my recovery is gone.

Hi Guys,
Hoping you can help me with this.
I was originally running Slimkat 4.4.4 and had the latest TWRP installed.
I downloaded the file for LPX13D and extracted all of the files right down to the Flash-all.bat and the images for bootloader, radio, and the system.
I ran the Flash-all.bat, and it installed everything successfully. The device booted, and voila, I am on 5.0 now.
The problem now, is that when I reboot into recovery, I am instead met with the little android guy laying on his back, with a red triange/exclamation point in his chest.
No problem, I say to myself. I'll just flash TWRP manually.
So I go to the bootloader, and try the command fastboot flash recovery recovery.img (renamed to make it faster to type.)
It goes through the motions, and says it was successful.
But when I go to recovery, it's the same red triange guy still.
I tried pressing volume up, power+volume up, etc. No dice. After about 30 seconds, it reboots on it's own back to system.
When I connect it to the Nexus Root Toolkit, and click on Flash recovery, and then choose TWRP latest, I get a window that pops up that tells me :
______
File Dependency Download
Status: Stock Kernel: Not Present - Need to download (this is in red)
Then a button that says "Download + Update All File Dependencies"
So what's my best option here? Should I let the NRT update the dependencies?

Twrp is not optimized yet well like cwm is for andorid l

Recovery won't work AT ALL no matter what you do until you reflash a KK userdata.img, which also wipes all data in the process.
Lethargy said:
I flashed the new developer preview for 5 minutes or so then went to revert. Recovery wouldn't boot not matter what I flashed, until I flashed a KK userdata.img. So it seems like the new developer preview changes the internal storage/data partition more then the old one.

Well, Twrp worked until I rebooted and then tried going back to it. Then bam! back to the error dude with the triangle.
So, I flashed cwm again, and that one seems to be persisting after a reboot, so I guess I'm stuck with cwm for now....
I also flashed the boot.img and the supersu update to get root working, and it seems to be going well now.
Cwm tells me that I may have lost root immediately after flashing the supersu update, but when I reboot, root is actually working. What a weird bunch of crap to go through.

Okay:
So I extract the userdata from a 4.4.4 stock image, yes? If not, can you point me in the direction of the correct userdata.img
I assume the correct order and syntax is:
fastboot flash userdata userdata.img
fastboot reboot-bootloader
fastbook flash recovery twrp.img
Fastboot reboot-bootloader
Select recovery
Wipe data/Factory reset, and then and reboot system.
Set up phone as normal.
Have I overlooked anything?

Yeah. Don't need to boot into recovery and wipe data since flashing a .img with fastboot while in bootloader erases it first then flashes. Just make sure you backup your stuff, including internal storage, off to a PC first if you have anything important.

Unable to boot into recovery but able to boot system

Hi I wonder if anyone can help me. My tf700 is running Zombi-Pop 5.1.1-OMNI-DEODEX RC2 . I may have wrecked my recovery and boot-loader. My Infinity is unlocked and rooted and had TWRP 2..7.00 or roughly that. In preparation for installing KatKiss 6.0.1 . I updated TWRP to [RECOVERY] KANG TWRP TF700T [email protected] JAN 4 from within TWRP and it completed ok. When I went to reboot into recovery I got a unable to boot error boot-image is unreadable X000000 or something like that, But I am able to boot the system which seems to be working OK. Does anyone know if the is anyway for me to re-flash a working recovery or am I stuck without a recovery? If anyone can help me with this I would much appreciate it.
Cheers Al-Man
ps. I have read loads of posts but I am still unsure as to what is the best course of action. I don't want to make it totally useless.

Your bootloader is fine or you would not be able to boot Android.
Kang TWRP 2.8.x is fine for any current rom so that is not the problem either.
Did you let the tablet reboot after the recovery flash? Sounds to me as if that was when things went south.
So fastboot flash the recovery, then reboot to system once before you try to boot into recovery.
If you don't know how to fastboot flash it's high time you learned it.

You could also use flashify or dd commands if you have root.

I then try fastboot reboot and all I get is
rebooting......
on the boot loader screen it reads just under the boot version
Starting Fastboot USB download protocol this is constantly showing every time I boot to the boot loader.
and then I reboot from the tablet and its back to square one .

I have seen many cases of "unrecoverable bootloader error" but never that you could still boot into system with that error. So I have no idea what is going on for you, but the only method I know of to successfully recover from a unrecoverable bootloader error is to flash the Asus system blob in fastboot after fastboot erasing each major partition. We call it a buster99 and you'll find it here:

Before you do that why don't you try to 'fastboot boot recovery twrp.img' instead of flashing it. You should still be able to use TWRP as usual, flash a rom with it etc. It just does not get installed on the tablet....
See if you can use the recovery that way...

Any other suggestions, I don't like the sound of Buster 99 also tablet is the wife's.

Buster99 has been a tablet saver for many users.
But if you don't want to do the whole thing try to fastboot erase recovery, cache and misc, then flash TWRP again and see if you can boot it.
