Hi, I am a happy owner of the HP Slate 7 Extreme which is basically the same device as you guys are using.I am still on the 4.2 Jelly bean since HP are not pushing over the air updates with our devices.I want to use the script from the development forum "[Script] [Utility] Nvidia Tegra Note 7 Kitkat Unlock BL, Restore, Recovery, & Root", I want to know if anyone has tried to use it with the Slate Extreme or if it simply should work on the Jelly Bean aswell. Thanks guys.

i have not test that yet but i believe it should work because i have tested the 4.4.2 and 4.2.2 evga ROM from here using the cwm install from sdcard method..

http://forum.xda-developers.com/show....php?t=2627671

The only thing that puzzles me now is i am unable to perform a system recovery from HP update.zip using cwm.

http://h10025.www1.hp.com/ewfrf/wc/s...t=6608632#N147

So right now i am stuck with 4.2.2 evga ROM all is good and functional.

I have read some post that by updating OTA fix issue in 4.4 but i have no idea on how to get the OTA update.

p/s: This is my first tablet and root attempt...

edit:

i found out that rootjunky has already released the 4.4.2 with 2.3 OTA i will give it a try and feedback later

First, nope, you'll still get freezing. I've tried all the ROMs.

Second, If you want to go back to HP's recovery, do the following:
  1. Create a copy of update.zip and navigate to META-INF\com\google\android and open up updater-script
  2. Delete the first three lines.
  3. Transfer your new update.zip to your device and flash. Allow it to re-write the recovery partition.
  4. NOTE THAT YOUR DEVICE WILL NOT ADVANCE PAST THE BOOT ANIMATION. THIS IS NORMAL.
  5. Copy the original update.zip to a SD card and insert it into the device.
  6. Now go to the HP recovery partition that now exists on your device and follow HP's restore instructions.
  7. You're done, the stock 4.2.2 that came with your device is now installed.

Had to figure this out the hard way after I lost my original backup.

To the original poster, you can get it to work, but you need to make modifications to the script's fastboot commands (they will require "fastboot -i 0x03F0" before they will do anything) and you will need to setup your machine for ADB with the Slate 7 Extreme. It won't work out of the box, you can find support for that here: http://h30434.www3.hp.com/t5/Android...s/td-p/2574571

There was an individual who has received the 4.4.2 update from HP on his Slate Extreme over at the HP forums. I believe he stated he received 20 units donated directly from HP and was wondering why only 1 of them received the update. I believe the reason stated is that he most likely received a non-retail unit by accident. Not sure if he ever dumped the ROM or even knows how. I don't know either otherwise I'd try to contact him to get him to do so.

I did flash the modified update.zip but CWM doesn't give me the option to re-write the recovery partition. I go straight to "Install from sdcard complete". How is that re-write done?

*Update* All done - Had to select NO to questions on reboot (Replace recovery and root). Thanks so much - back to stock 4.2.2

I downloaded a script editor and deleted the first three lines of updater script but it still fails to flash.

I have the 4450 extreme and one the things that was a little different- is that I had put the update zip on the sd card prior and it did the update on its own... WEIRD but acceptable! rooted and on 4.4.2- thanks man!

I didn't have any luck doing it this way. I ended up getting there by a slightly different avenue.

My s7e was totally non functional beyong fastboot and recovery mode being operational. I ended up downloading tegratools 2.2. Using the fastboot included in that I unlocked my boot loader with fastboot by the command
Code:
fastboot -i 0x03F0 oem unlock
(The '-i 0x03F0' is a code relating to the specific model, apparently without this the tablet will ignore your command. Please also remember that the unlock factory resets the tablet.)

It may be overboard again, but I also formatted all the system partitions
Code:
fastboot -i 0x03F0 erase boot 
fastboot -i 0x03F0 erase system 
fastboot -i 0x03F0 erase userdata 
fastboot -i 0x03F0 erase cache 
fastboot -i 0x03F0 erase preinstall 
fastboot -i 0x03F0 reboot
I uploaded cwm recovery from the above version of tegratools to my s7e as it seems a bit more forgiving with signatures than the stock recovery. I used that to upload a version of update.zip with the "assert" lines removed from META-INF\com\google\android\updater-script. I also self signed the .zip to reduce the likelyhood of my upload being rejected by the tablet, it may not be needed, but I did it anyway.
Code:
adb sideload slate7update-signed.zip
when completing the firmware flash, apparently there is a common problem of the kernel not flashing correctly when recovery takes place and giving an "Error 7", this is the problem I think you solved by re-writing the unmodified firmware (but that didn't work for me)

Anyway I had to fix it by dropping back to fastboot and flashing it to "staging", which puts the kernel in a placeholder until the next boot, at which point the kernel will be written to the correct spot. Because of this writing to the correct partition, you will notice a quick double-boot as the updated kernel is written to the correct point in firmware.
Code:
fastboot -i 0x03F0 flash staging "c:\fastboot-s7e\blob"
I hope this helps.
Oh and to those curious, the beats version appears incompatible with the standard s7e, I tried modifying a rom in the same way as above and it just went to a blank screen. My guess is they've done some form of sanity check in the kernel, given that every "beats" version I've read about in tablets has been a software-only modification. I've not bothered trying to use the beats version rom with the s7e kernel, I'll leave that for someone else to try in greater depth as I'm just happy that I got everything working again.

references:
Fastboot: This is a copy of the twrp/cwm roms as well as fastboot & adb taken from tegratools 2.2 mentioned above.
SignApk: The java files and self signing certificate I used to sign the .zip file. It was actually a bit of a pain to find a working signapk.jar that had the valid certificates included, most were broken in one way or another when trying to sign on ubuntu 12.04.
slate7update-signed.zip: A signed copy of update.zip with META-INF\com\google\android\updater-script modified to remove the assert validation lines sanity checks, be careful with this, you could nuke your tablet if you use it on an incompatible bit of hardware.
guide.txt: A full how-to with a number of things I've omitted from this response.

To those wondering, I collated the above procedure from a dozen different links on a good four or five websites, including a number of threads here on XDA. Thank you to anyone out there that contributed to the information I found, you really made my day so much better in being able to recover my tablet.
