Got a new firmware update tonight. Tablet seems faster now. Anyone else get it? Glad to see they are still updating this tab.
i also got the update on my dell venue 7 3740. but it disabled the fastboot, now i cant root it.Got a new firmware update tonight. Tablet seems faster now. Anyone else get it? Glad to see they are still updating this tab.
Take a look at the kernel source for the 7840 it has a py script intended to unpack / pack the unsigned images a small modification can be made to the script to take into account the Sig . if you wanna better idea of the Intel image assembly I suggest at signing up for the baytrail bsp from wind river or other vendor.It's still 4.4.4 and the source code hasn't shown any signs of change yet either. Still can't pull the boot.img or recovery.img from the device, having trouble splitting the ones from hharte, still no email replies yet, kinda hate to think my email yesterday caused this as this isn't an answer to my questions, I'm just not stoked about an update that is basically the same as previous, going to snatch it and post it for those who think it's worthy of an update. excuse this rant, been sweating out my days and nights trying with this tablet, not going to stop, just isn't much of an update to me. Sound is still distorted, which really grinds my gears. ... ok, I feel an insey bit better. thanks 4 reading my O.
Thanks for the tools that'll hopefully help a great deal. I've played with the 7840 kernel code for two days and still was left with a non-flashable boot.unsigned.img, I truly appreciate any help I can get with this. I've tried like 5 different device tree cobinations and probably more than that. Hopefully this will truly bring a light for a breakthrough.

If your on windows this might unpack the signed image and repack as a unsigned image so you'll need the boot loader unlocked.

You sure about that? I only saw the 7840 mentioned on Dell's support site for the Apr 21 update to Lollipop.Lollipop is suppose to start rolling out to the Venue xx40 series on Tuesday April 21st, I suspect this is a preliminary update to make the device work for lollipop. The 3x30 saw similar small updates days before the JB to KK update.
I saw it in a 3740 thread and the 7840 all three devices are merrifield based tablets and the last email I got from dell legal said it was going to start rolling on the 21st and that at this time they have no word on if or when it would be available for the 3x30 I'd post the email but it full of Dell Private Confidential headings.You sure about that?

This andimgtool is very interesting, works on 3830, changes output boot.img into an img that 7840 packing script can unpack and repack that flashes and works.Take a look at the kernel source for the 7840 it has a py script intended to unpack / pack the unsigned images a small modification can be made to the script to take into account the Sig . if you wanna better idea of the Intel image assembly I suggest at signing up for the baytrail bsp from wind river or other vendor.

it removes the 480byte signature and corrects the image flag to be unsigned what ever image it wasThis andimgtool is very interesting, works on 3830, changes output boot.img into an img that 7840 packing script can unpack and repack that flashes and works.

Yeah the uos firmware doesn't validate the sigboot.img wasn't signed, haven't used or seen a signed boot.img since I unlocked the bootloader on this tablet.
pm-cz scripts leave the signature ? Never checked.

Alright maybe I am missing a major point if dude are capable of unpacking, repacking and all that good stuff, My question is wtf, why not me? what on earth can i do to get the appropriate file sizes to know where the boot sector is so I can extract it and if need be modify a script that'll allow me to do all of this and re-flash it for testing? the 7840 builds so smooth and I am losing my mind. I feel like theres a whole lot of know how in a small click. Initiate me, make me an apprentice, study buddy. idk I'm loosing my mind. Must have over 20GB worth of trials and errors. I'm going to Google the mentions of sdc from earlier but am really not sure of what I am looking for. If I could get a pm tutor that'd be nice. I can do all the work. But nothing I have tried so far has been acceptable. I'm getting other things done but this is my priority goal. Thanks for helping guys. I'm generous when I got it. I fell so behind in learning the specs of this new device to be successful at what I wanna do with it. There I go again giving reading material for the pooper seat. I need to build and sign a Sig for starts, lol, if momma only knew what I did all day and night now, lol.Yeah the uos firmware doesn't validate the sig
The 7840 build script is be able to unpack and repack your boot.img, don't know if it will boot on your tablet as I don't have your tablet and not interested in it, I did download a 3840 boot.img, unpacked and repacked boot.img flashed to my tablet just to see if it would flash, and it does flash without any problems, wont boot cause my tablet is a 3830.Alright maybe I am missing a major point if dude are capable of unpacking, repacking and all that good stuff, My question is wtf, why not me? what on earth can i do to get the appropriate file sizes to know where the boot sector is so I can extract it and if need be modify a script that'll allow me to do all of this and re-flash it for testing? the 7840 builds so smooth and I am losing my mind.
