Hi,

It isn't exactly "download mode" (like on a smartphone as Samsung Galaxy Sx) but a restart in "bootloader mode".

To do this you have to use this step :
.../...
1st step : you must generate the file parameter.txt
Restart in bootloader mode (with Cydia Impactor, or with a command line using Adb.exe like adb reboot booloader).
.../...

Do not be surprised, when the tablet restarts in bootloader mode : the screen remains frozen on the HP logo .
But HP Slate isn't stuck ;)
If you were able to install the correct drivers (not standard drivers, nor ADB drivers) you will be able to continue with ROM_Dumper_Tool.exe or ROM_Flash_Tool_137.exe... depends on where you left off.

I hope you will get there, by following the process everything should be fine.
But if you fail to enter in bootloader mode, I can't help you much more.

Ooooooooo OK well then it boots into download mode then the comp(win8) says USB unreconginzed. Doesnt show up in adb either. Installed moborobo and used the .inf file to update drivers....hmmm

I remember !
You must have RockChip USB drivers for your HP Slate to be recognized with USB in "bootloader mode".

Try do download and install this : Rockusb Driver v3.5 and/or this : Rockchip driver USB fix

Choose the right version for you Windows (or maybe try many of them). Then try to reboot the computer too.

Hoping that it will help you! :good:

(I've tried in both windows 8 x64 and 10 x64 and it works)

@poulette73 cant seem to get it to work right. Tried installing drivers(multiple) and the fix, made sure it copied the files, while in bootloader, ot shows up as rockusb class but with triangle. Should I not be in bootloader when installing these drivers? Followed guide to unsigned drivers but while not in bootloader it tells me that theres no driver file found make sure ita for x64 blahblahblah.

Aaaargh..... difficult to go further without having the material at hand.

Yes you're right, when you reboot with HP Slate 7 :
- in "booloader mode" AND
- in Windows 8 with "non-signed drivers verification check" (sorry for my english)

You can go into Device Manager, choose devices with triangle and select "Have drivers" then go to the .inf files and try them..

I'm very sorry if it does not work for you.... :crying:

I think I have been as far as I could, really sorry :confused:

Here's how I make a rollback to 1.05.14 version on my HP Slate 7 2800 tablet (sorry for english, I'm french).

Firstly a big thank to all those who advised me in PMs... !!

Note : I will neither be held liable in case of mishandling or brick. So be careful or do not start these operations if you don't feel able to accomplish them.

First of all, you need to get RK 2.1 tool from finless (thanks to Bob !) : http://freaktab.com/forum/developme...p-your-rk-device-rom-with-the-new-rk-2-1-tool
Download link : http://www.freak-tab.de/finless/rk_tool21_how_to.zip

I assume you have already installed the ADB drivers. If it's not the case, you can continue with this topic from MrTheV : http://forum.xda-developers.com/showthread.php?t=2660208
Or install Morobo here : http://www.moborobo.com/ or else Google it.
Yo may need Cydia Impactor 0.9.14 (by Saurik) later, download it here : http://www.cydiaimpactor.com/ to root, or easily restart in bootloader mode.

1st step : you must generate the file parameter.txt
Restart in bootloader mode (with Cydia Impactor, or with a command line using Adb.exe like adb reboot booloader).
Use the program ROM_Dumper_Tool.exe (on the third tab Advanced Function) and read and follow the file INSTRUCTIONS_README_FIRST.TXT
Suppose that at this stage you have exported the file, rename it, and have it changed and saved as specified in the documentation.

2nd step : download other archives
[ROM] Stock for HP Slate 7 2800 (by rjwil1086) : http://forum.xda-developers.com/showthread.php?t=2608181
Download link : http://goo.gl/f5bL3p
[CWM] 6.0.3.3 for HP Slate 7 (by rjwil1086) : http://forum.xda-developers.com/show....php?t=2599500
Download link : http://goo.gl/GDbDyc

Then, you have to use the tool in Flasher_tool\ROM_Flash_Tool_137.exe
With parameter.txt, we will flash ONLY boot.img contained in the archive pine-update-signed.zip and recovery.img contained in the second archive CWM 6.0.3.3.zip (read the instructions carefully).

Now we have a functional CWM recovery.

3rd step : Back to 1.05.06
Now reboot in CWM recovery and flash the pine-update-signed.zip file already got.
Then you have to put the stock recovery.
Download it here : http://goo.gl/cGtlt1

We'll return into bootloader mode, and flash ONLY this stock recovery ( 20131217.recovery.img ) located in the zip with the tool Flasher Tool\ ROM_Flash_Tool_137.exe.

We now have an HP Slate 7 in 1.05.06 version with a 1.05.10 recovery.
You can now reboot into recovery mode and flash the update.zip of 1.05.10 in order to be consistent.
Download link here (and rename it to update.zip) : http://www.4shared.com/zip/YE4jxMtoba/update_10510_.html

4th step : Back to 1.05.14
Reboot in recovery mode and flash the update.zip 1.05.14
Download link here (and rename it to update.zip) : http://www.4shared.com/zip/ZBxJS9Pdce/update_10514_.html

You can now easily root your tablet with shuame, Cydia Impactor, or a lot of others methods available on XDA. Then install SuperSU (from Chainfire).

5th step : Back to CWM Recovery
You can use my method here : http://forum.xda-developers.com/showthread.php?t=2570936

Others credits goes to :

Prerequisites :
- The battery in your tablet should be fully charged, or at least 50% to avoid a brick.
- You must have CWM Recovery installed.
- You must download this update : 4shared (Download link 1) or Mega (Download link 2)


Content of this 1.05.18 update :
- stock bootloader
- stock boot
- stock recovery
- stock apps and system (all untouched)
- root !

How to install :

- Simply reboot in CWM recovery mode.
- Flash this update file : update-cwm-slate-7-supersu-1.05.18.zip
- Reboot after update completed.


And if you want to retrieve CWM 6.0.3.3 Recovery, you can repeat the operation already mentioned in an earlier post :

Hello,
Sorry to reply to an old topic but I am the owner of an HP Slate 7 2800, and would like to flash with your " update-cwm-slate-7-supersu-1.05.18.zip " but it is no more available on Mega or 4shared, would you mind to reupload it somewhere ? Thank you very much in advance :unsure:

    General Warning, read before doing anything to your tablet:
    Whenever you try to do anything to your system ALWAYS back up everything since there is always the chance that something might go wrong.
    If something goes wrong you have to download and install the boot images from HP support, HP Slate 7 2800 restore image and HP Slate 7 4600 restore image, the install instructions are in the same page in "How to install".
    Some users have had problems with the alternative rooting method using Bin4ry's tool, since it is some I will asume it is something someone is not doing correctly, because other users with the same slate model have been able to root, if it is your case where you can't actually root post here I'll try to help you in any way I can.
    To end this sort of disclaimer, my Slate 7 is the model 4600 so I'm not actually able to try the method with other slate models, anyhow other users have had no problem but as always this could be your case and I'm not responsible in any way if you brick your device.


    Cydia's Impactor tool has been updated and it's working with all versions of the roms (Confirmed by users).
    Bin4ry's rooting tool has been updated, chances are it's more friendly user and won't throw any errors, up to you to try it out.


    Just as a side note, the screenshots below are just for reference, they are not the same drivers/devices, they are only meant for you to know where to click.

    Step 1: Download Tool Package (this is an old package, the drivers in the package works but you NEED TO ALSO DOWNLOAD Cydia's Impactor (Link to home page in case you are interested in reading a bit) and Googles ADB Drivers with a little modification in the ini file so it installs the driver for our HP Slate 7 tablet). If your Slate 7 model is 2800, you have to also download Moborobo that will find and install the drivers for you. I've received messages from users who have had both good luck and no luck installing the drivers, this must be dependant on your operative system and administrative rights, I did all this steps on a Windows 8 64bits machine with administrative privileges.
    Download latest Cydia's impactor tool from the link above. The one in the package won't help you if you are trying to root v9 and above.

    Step 2: Unzip the package anywhere you like, meanwhile go to your tablet and set it to USB Debugging.

    usb-debugging.jpg

    YOU MUST SET IT ON USB DEBUGGING MODE, else nothing that you try will work.

    Step 3 OPTIONAL: Just in case if your computer doesnt realize there is a device connected you need to copy the file in "\.android\adb_usb.ini" over to your user path "%USERPROFILE%\.android\" and reboot the computer (Just in case it wont recognize a device as connected).

    Step 4: Now open the computers Device Manager and you will see something similar to this picture

    a1.JPG


    Step 5: Right click the HP Device and choose to update driver, search for drivers in the computer (2nd option), then "let me pick from a list of device" as follows:

    a2.JPG


    Step 6: Next click in "have disk" and navigate to where you unpacked the file downloaded earlier and choose the ini file.

    a3.JPG


    a4.JPG

    Pictures for reference only.

    Step 7:All you have left is open Cydia's Impactor tool, you will see a small window with a default command on screen which is the following:
    Code:
    # drop SuperSU su to /system/xbin/su
    Just click Start next to it aaaaand you are done!
    (PS: If this worked you are done, skip Step 7B. If you were unable to root your device try Step 7B)

    Step 7B (ONLY IF Cydia's tool did not work): Warning: I've received messages from some users that this exploit has left them on bootloops, this method is tested on the 4600 model, if you have another and it works please do post your results, if you have problems all you have to do is download your model ROM from HP support and boot it through your microSD card to restore factory settings, also check in Bin4ry's thread for information if it is your case, if you find another method please do let us know ;) . DO THIS ONLY IF STEP 7 FAILED, you will have to download the following rooting tool from Bin4ry's XDA thread, execute "RunMe.bat" and use method 1 and follow the on-screen instructions (This method will reboot your tablet 3 times if I remember correctly, after 2 reboots it will be stuck in a black screen for a couple of minutes (or more, it took me around 10 minutes) this is as it pushes the files for superuser, don't panic).

    You can check your build version as it's shown in the following picture.
    Slate_7_model_number.jpg



    Just open an app like Titanium Backup which needs root to see if it worked.

    This method is simple plus you don't have to download anything chinese or unnecesary software into your computer, the tutorial is really long because I tried to be as detailed as posible but in the end you shouldnt take more than 5 minutes (The downloads might take a bit longer though for the SDK), I would take screenshots of the process but my computer runs on a Spanish version of Windows (The same reason why you might see things with different names I was just trying to guess the device manager label part).

    If you have any question feel free to ask (of course... as long as it hasn't been asked again and again in the thread ;) ) and if it worked for you a thanks would be awesome so more users will try

    PS: My Slate 7 model is the 4600 but it should work with others slates and for that matters, with any tablet as long as the adb driver is recognized.
    PS2: If you could upload the package into a new mirror that might help more people.
    PS3: Updated to March 16th 2014.
    PS4: I just realized the screenshots facilitated by another user have been deleted, will try to find new ones.
    PS5: If this helped you, please do thank, this way more users will benefit from it.

    We'll return into bootloader mode, and flash ONLY this stock recovery ( 20131217.recovery.img ) located in the zip with the tool Flasher Tool\ ROM_Flash_Tool_137.exe.

    We now have an HP Slate 7 in 1.05.06 version with a 1.05.10 recovery.

    Easy root success

    HP slate7 2801 easily rooted just by this VROOT english software, just USB debug on, antivirus disable as it may inhibit VROOT installation( for me NOD32 antivirus)
    just install this software
    2
    Doesn't work. When I run Impactor I get an error: Signature bugs unavailable.

    I tried updating impactor and I have the latest version.

    I can factory reset and root again, but how do I stop the OTA update prompts from popping up?

    Ok I found a working root for latest 1.05.10 patch you can download here.

    Once you download the tool you have to run the "RunMe.bat" file and follow the instructions, the method that worked was method 1 "New Standard-Root", it seems to also come with an unroot option for those who have asked for it, havent tried it though.

    PS: Be careful when "press a key to continue now" because you can make it a double tap and miss a step, it won't brick the device but you will take longer.

    Hello


    Thanks for the tips.

    I think I have found a simpler method to root the HP Slate 7 2800 from a Windows 7 PC.

    At first, I installed adb drivers for HP slate 7 2800 as described here:
    http://forum.xda-developers.com/showthread.php?p=50592161

    Then I downloaded the LATEST Cydia Impactor from here:
    http://www.cydiaimpactor.com/
    (the previous version did not work).
    I ran Cydia Impactor and clicked Start and I gained root access to my HP slate 7
