For root again with recovery after the 4.4.2 update ...

+ Flash TWRP

+ Start TWRP

+ Leave TWRP and say yes when it asks you for superuser installation.

+ restart

+ Recovery is replaced by the original and Slate is rooted.

Re-root with CWM fails on my Slate.

----

(My 4.4.2 OTA installation was made with integrated updater. Ramdisk without changes)

My experience with 4.4.2:

-Galerie stops when it was launched from the desktop

-Rotation was changed, but it is malfunctioning

-Apps move to SD is possible :victory:

-HP Multi-window not error-free

-Notifications tone volume too loud at minimum setting

Greetings to all.

I ask immediately apologize for my terrible English and for my questions that may seem trivial and repetitive.

Unfortunately I can't speak English very well and I'm not very familiar with Android modding.

I upgraded my HP Slate 21 to KitKat 4.4.2 by OTA.

Unfortunately now I can't copy files on the external sd card or on usb pendrive and so I'm forced to root my HP Slate 21 s-100.

To root my HP Slate 21 s-100 full stock with stock recovery, running 4.4.2 KitKat I have to follow this guide: http://xdaforums.com/showthread.php?p=56427281

, correct?

Is there a video guide on youtube?
[General Questions and Answers] evilpfeiffers:
Hi,

you must unlock the bootloader and install TWRP, instructions see here.

After that you can flash my OTA zip, see the steps here, rooting can be done directly in TWRP, after flashing the OTA zip it asks you to install SuperSU, say yes here.

SD Card / USB access:

For me access to external SD and USB Drive (ports on the back of the slate) is working fine.

Hello EP, sorry for the huge quote, I'm on my phone. I managed to brick my Slate (it won't manage to get bast the HP startup animation). I seemed to kill it while installing phobos-SuperSU-v2.02.img. I didn't get as far as getting TWRP in. I cannot get regular ADB or fastboot to work anymore as they don't see my Slate. I used the stock Android recover to reset to factory conditions and no luck booting past the animation. The stock recovery option to update from SD and ADB both failed with this rom as it says is has a bad footer and signature verification failed. Am I permanently bricked at this point?

Thanks!

So it appears that HP has removed the 4.2.2 builds from the FTP servers. This URL no longer works:

http://h10025.www1.hp.com/ewfrf/wc/...c=en&product=6967505&tmp_track_link=ot_search

It did lead me to the HP FTP servers which I downloaded 500 MB builds over and over at random (they are all named Update.zip and are buried inside hundreds of random folder names). No luck, but I did learn the product names for many of HP's Android devices. I guess I'll call tech support tomorrow and see if they have the ability to escalate a request for a recovery file that I can re-install. Night all. ;)
[General Questions and Answers] evilpfeiffers:
Hi,

think you've already tried, but is the key combination to start the slate in bootloader (fastboot) mode not working?

With the slate powered off, press and hold the Volume down button and Power button at the same time, hold it till you see the bootloader screen.

greetz,

evilp
[General Questions and Answers] charleypick:
Thanks,

I was able to get into fast boot, but from that screen ADB is not seeing any devices, so I try recovery mode (the default one that comes with Android) from there and select apply update from ADB. When I run that it says the OTA KitKat package: "E:footer is wrong", "E:signature verification failed" then aborts the installation.

So I guess I need a signed install image.

I read about using Fastboot flash:raw boot but the ZIP file form OTA Kitkat does not contain .img or .gz files I can install.

Okay, I was able to install TWRP (Yay!) from Fastboot and installed the OTA kitkat image. as well as the bootloader.

any easy way to go back from 4.4.2

My HP Slate 21 -k100 all-in-one has recently updated to 4.42 and I can't use SD card and USB stick as previously mentioned

Is there any easy way of reverting back to prev version on OS

Rooting isn't super-easy if you have not done it before. I'd suggest reading all the posts Evil linked to before trying it. I rooted a different device before but got a bit mixed up with my Slate 21 and got stuck. You need to follow the steps exactly or it won't work.

Hi Charleypick,

Please I need your assistance. I have the exact scenario you have described, I'm stuck on the HP logo. I tried to flash the phobos-SuperSU-v2.02.img but it got stuck on the HP logo. I can get to the fastboot screen, and have tried flashing twrp and the OTA zips, I only get the errors you described.

Can you please give me the steps you used to successfully flash the twrp and then successfully flash the OTA?

I will really appreciate your help and assistance.

bolam
[General Questions and Answers] charleypick:
From the terminal on your PC or Mac, type:

fastboot flash recovery twrp_revovery_phobos_v2.img

This assumes you installed ADB and Fastboot into your PC and that you are in the same directory that contains the TWRP file. I reinstalled the OS via TWRP from an SD Card. It also assumes that your PC is connected to the USB port on the side of the Slate using a USB A to USB a cable. This is using the power button and volume down but to get into Fastboot.

confusing slate

I tried to unlock the bootloader of my newly acquired slate 21.

I installed the driver for win 8.1 and did

"adb reboot bootloader" .. so far so good.

But with ""fastboot oem unlock" I get

"error: device not found"

Instead I get on my slate a 'fast boot mode' menu? Where I can select an option provided "recovery mode"... :confused: See the picture[IMG="Fast boot mode hp slate"]http://h20564.www2.hp.com/hpsc/doc/public/imageServlet?DOCID=emr_na-c03915683-3/c03962114.jpg[/IMG]

Should I sideload a bootimage provided here? Or what should I do?

I have the updated ROM provided by HP (Android 4.4.2)

And yes I rooted several android devices before... but this one is confusing..

problem solved... was a driver issue. Installed moborobo for the proper driver for the slate.. and voila: Unlock option was available in bootloader.

I have found the solution for me here but I had to adopt it.

Download Google USB driver from here: http://xdaforums.com/showthread.php?t=2588979

Once downloaded, unzip the package, there’s a usb_driver directory. Inside there open “android_winusb.inf” with notepad.

Add the 3 lines below to the sections [Google.NTx86] and [Google.NTamd64]:

;slate21
%SingleAdbInterface% = USB_Install, USB\VID_0955&PID_7100
%CompositeAdbInterface% = USB_Install, USB\VID_0955&PID_7100&REV_0000

In Device manager, select the Slate 21device and go to driver -> update driver -> browser my computer for driver software, select the usb_driver directory you just edited.

[T-Mobile HTC One (M7)] dilyn:
After an hour or two of wondering why I couldn't get s-off on my phone, I realized that I was using a slightly outdated guide. Used Rumrunner instead of Moonshine, s-off acquired. I was trying to get my phone to be recognized as a Developer Edition, so I had to change the MID and CID. I was using a guide for changing the MID on here, but I guess silly me misread a step or something, and now here I am: the phone is stuck in fastboot mode. If I try to get into recovery it just flashes to the white HTC screen for less than a second and back into fastboot. Rebooting the bootloader just returns me to a black screen as if my phone were off.

When I plug my phone into my PC, I can here it dinging as if a device were plugged in, and when I go into Device Manager the port it's plugged into recognizes a device is there, but it says "Device failure enumeration" and gives me Code 43 (Windows has stopped this device because it has reported problems). Any attempt to access via fastboot (I've tried reflashing a recovery and clearing cache, as well as rebooting) simply returns <waiting for device>, and when running adb devices it returns that there aren't any devices attached (explains why fastboot commands aren't working).

Any ideas? Or is my phone gone forever?
