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.

Below is flashing same boot.img on my iview i-700 same results as 3830 both will flash the boot.img but neither can boot from image.

Which device 3840 Correct? And you already unlocked the BL?
[Dell Venue] vampirefo:
LOL, yeah, if he hasn't unlocked his bootloader, he just been wasting his time. :good::good:
[Dell Venue] golfyrider:
my 3840 has updated ......... it seem faster? :confused:

No difference. :silly:
[Dell Venue] vampirefo:
I don't have the tablet, but looking at the update, I didn't see anything to improve the tablet, change to fastboot binary is the main change, apps were updated.
[Dell Venue] golfyrider:
i cant root it after update.

can not boot to fastboot mode
[Dell Venue] vampirefo:
You try

adb reboot bootloader
[Dell Venue] kgvs72:
Reset keys don't work

I received the firmware update, and it seems like the power + volume down button combo for entering recovery mode has either changed or somehow disabled. I tried different combinations, nothing worked. I'm a noob when it comes to ADB and rooting, but after setting up ADB and fastboot, I was able to boot into Recovery and reset the tablet. I got the Windows drivers from Dell Opensource. If you go up a couple directories, there's also info and drivers for other dell devices:

Venue_7_3730_CloverTrail_plus/

Venue_7_3740_Merrifield/

Venue_8_3830_CloverTrail_plus/

Venue_8_3840_Merrifield/

Venue_8_7840_Merrifield/

It's a well built tablet, but it seems like this tablet is more of a guinea pig for testing/rooting than for actual use; it lags, I barely have anything running, and don't like the bloatware installed. I hope that a lollipop update fixes some of these issues, but its achilles might the 1gb of ram.
[Dell Venue] justlovejoy:
It happened after I was treating and needed to go back to stock unbrick method. I actually didn't approve the update, it just rebooted.

I thought the not getting updates was from having am unsigned boot.img tho?

Yes my bootloader is unlocked but its after flashing the unbrick that it went back to being locked again I guess.
[Dell Venue] vampirefo:
You can now flash unsigned boot.img?

---------- Post added at 04:31 PM ---------- Previous post was at 04:28 PM ----------

Fastboot binary was changed, so that's why combo doesn't work, as each update happens dell may block fastboot altogether.
[Dell Venue] justlovejoy:
Never have it thought that way but I can't build a boot.img (signed or unsigned) to flash. That's what I'm after though. Or unpack and repack and flash but If I were able to compile an unsigned boot.img, I'd be closer to being a happy camper. That and recovery are my main objectives. So with greater detail what I was implying was this scenario:

-I Bork everything and need to use the unbricker method

-Afterwards I'm back to the point of getting updates again, ota.

-I got two bak to back updates instead of one.

-Swiped it and then shared

-went back to the unbricker method

-then flashed the half root (cause it enables unsecured adbd)

-rooted fully with superSu and am back to square one.
[Dell Venue] vampirefo:
Have you tried to flash the boot.img I uploaded?
[Dell Venue] justlovejoy:
Memory fails me as to which one that is, sorry, could you link me?
[Dell Venue] vampirefo:

[Dell Venue] justlovejoy:
Just did and it flashed without error. although I am at a screen that states:

[Dell Venue] vampirefo:
So you require a signature, http://xdaforums.com/showpost.php?p=56338132&postcount=4

hhrate shows how to sign the boot.img
[Dell Venue] justlovejoy:
So I have tried this method before, probably with a different image. How would I get the image to build like how you have though? I have My Surface Tab downloading a downgraded OS recovery that's 3GB and Everyone is on wifi at the moment, It may take a while before I can reboot to ubuntu to do this as I have not been familiarized with a way to do it on win7-64-pro yet. I'm sure cygen but it hsdn't helped me since... I cant remember

I was able to pickup a 3840 today at bestbuy for $119

http://www.bestbuy.com/site/dell-ve...lack/9990127.p?id=1219459039807&skuId=9990127

The tablet had an update waiting, downloaded update, then rooted tablet, pulled boot.img then repack boot.img, works just fine for me.

[Dell Venue] social-design-concepts:
lol I just order one to pick up after work did you have to flash the uos ifwi file to have unsecure boot?

I passed it up Tuesday when I could of got it priced matched for $99 but it turned out I needed a 64bit soc for a work project and its the only one unlocked

My biggest concern is going to be downgrading to 2cores 2threads and a 1GB of ram.

It really made no sense to produce a tablet with half the specs of the previous model.

Well just got around to installing cwm 51 recovery on this 3840.
[Dell Venue] vampirefo:
Well, while I have enjoyed having a new tablet to play with, reality stepped in. I use a lot of GPS stuff with me on the go, this device doesn't have GPS, So I would need to take two devices with me instead of one.

The 3840 tablet is nice, but a step down from 3830, my 3830 has twice the ram and twice the space of the 3840, plus a great GPS.

I may end up returning this tablet, I bought it cause of the price, now kind of having buyers remorse.

Returned tablet a few hours ago.
[Dell Venue] zmbutt:
New update available at OTA, I didn't install it yet, anyone else tried ?
[Dell Venue] vampirefo:
Does the update have a date or name? Any info on the update?
[Dell Venue] zmbutt:
No, it just said, "dell update available" I got 3840.
[Dell Venue] vampirefo:
No one else seems to have gotten an update, could be you didn't update when the old update came out.
[Dell Venue] zmbutt:
I've always up to date, I will check it again when i got time to update. and then post here :)
[Dell Venue] vampirefo:
Well let's hope it's lollipop, I just got done compiling 5.0.2 for 3830 of course it won't boot, don't have lollipop kernel, lol. Right now trying to compile 4.4.4 for 3830 see how it goes.

Anyway wish you luck.
[Dell Venue] social-design-concepts:
You using pure aosp or one of the official Intel BSP sources ? Did you try disabling selinux in the kernel config and the device tree?

What kernel source are you using? Intel's official source for lollipop is still 3.10.20 I guess the real issue is the lack of an official kconfig for the device but I know people were able to build and boot the DV8 3830 just by using the generic CTP kconfig.

I would suggest getting a custom kernel built and booting on 4.4.2 first so you know the issues are the kernel and not the android build.
[Dell Venue] vampirefo:
Pure AOSP, using prebuilt kitkat kernel.
[Dell Venue] vampirefo:
I will try the 4.3 kernel when I get home, Logcat didn't work, I could adb and issue mount command and seen that system, cache, data and so on was mounted, then it would just reboot to recovery.
[Dell Venue] social-design-concepts:
That was on lollipop? I think you need to look at cm-12.1 system core commits for init , lollipop aosp doesn't support .ko module loading Intel even has a reference in to it not being allowed in there kernel build script on android-ia cm had to either revert the commit or re add support for ko module loading in init.

Crashing and booting into recovery mean a critical service is failing to start with out logcat though hard to debug which one. Put a copy of logcat in /sbin that should allow you to debug maybe hash out any critical service in init.rc so it just hangs instead of rebooting into recovery.
[Dell Venue] vampirefo:
4.3 kernel just hangs doesn't reboot into recovery. I am looking at 7840 lollipop boot.img it loads modules.
[Dell Venue] social-design-concepts:
this is in the fugu kernel make knew i saw it some where but i think i was mistaken on it being currently removed from init i read it somewhere

define build_kernel_module

$(error Use of external Kernel modules is not allowed)

[Dell Venue] vampirefo:
HELL YEAH!!!!!! 4.4.4 ASOP just compiled, boot took a while, but she booted, and wifi connected so, I have some success. She is slow but works. Pure AOSP 4.4.4.
[Dell Venue] social-design-concepts:
hell yeah buddy awesome news. . . . using stock 4.4.2 boot image i hope : )
[Dell Venue] vampirefo:
Yes using stock kernel, 4.4.2.

I added some files to stable the build reals well, still needs work and testing.

Need to find compatible gapps, for intel 4.4.4.

Guess it will be FrankenGApps-x86-20140826.zip, They seem big but couldn't find any others.
[Dell Venue] rinshid:
Is that is for 3830?
[Dell Venue] zmbutt:
Unfortunately, it was minor update, download took about 5 minutes and it flashed. Checked the version it still 4.4.4 :(

dunno, what did it change.
[Dell Venue] rinshid:
Did 3830 got 4.4.4 update???
[Dell Venue] vampirefo:
No, I built 4.4.4 from source, still a work in progress, rom runs some stuff doesn't work, it's a developer rom, not user rom.
[Dell Venue] rinshid:
Take ur own time :D

Finish the work:beer:

I am also rooted :p

It is lollipop I confirmed from Dell on G+.
[Dell Venue] quevon24:
There's any new update for venue 8 3830? Right now i'm with android 4.2.2 because i always had problems with 4.4 because some times the screen turns black and i have to lock and unlock the tablet to get the screen working again and this doesnt happen with 4.2.2 .

Thanks.
[Dell Venue] vampirefo:
I doubt it, lollipop would be a big update, not a small update.
[Dell Venue] graphdarnell:
Quick question: I flashed the Vamp-boot.img without problem, then proceeded to flash the CMW in your release.zip with your linux-tethered CMW. Completed fine except it still showed stock recovery. How did you make the CMW stick?
[Dell Venue] vampirefo:
Those recoveries are all temp recoveries, they don't install they are for fastboot mode.

To install recovery permanently you have to flash a permanent recovery, I did make one but never released it.

I have returned the 3840, looking to get another device. I don't release permanent recoveries for devices I don't own.
[Dell Venue] graphdarnell:
Thanks for the reply. Now I know I didn't miss anything.
[Dell Venue] Chaosblader:
have any update for 3840 ?

i want update to lollipop
[Dell Venue] vampirefo:
No, update.
[Dell Venue] cassfutbol:
Can anyone tell me how to remove the latest firmware update? I was told this would speed up my tablet.
[Dell Venue] vampirefo:
There is no way to remove an update, unless you backed up your device before applying update.

You can install older version that dell has on their open source website, No ideal what version that is though.
[Dell Venue] wiltzky:
Got a new firmware update tonight. Tablet seems faster now. Anyone else get it? Glad

helo,

i have problem about the dell venue 8 3840 tablet when i open the application and it says stopped or unfortunately then close automatically the application. now, my question is if i will update the firmware all error will be solved? and can you please send me the guide on how to update the firmware on my tablet? please help me and if ok with you kindly send to my email the procedure wilsonbataoilmay01@gmail.com...thank you so much:):):):):):):):):)
[Dell Venue] megaghostgamer:
I received an update recently as well. It does appear to modify the fastboot so I removed the lines in the updater script that flash the patch. I made a zip and flashed it through temp cwm. I'm wanting to say the tablet is faster however it still says there's an update. I guess it's depending on the fastboot patch. Anyways, if anyone would like to try the modified update that I did, I'll upload it. I'm still rooted and what not and yes I still have access to fastboot.
[Dell Venue] graphdarnell:
Would you please upload the patched zip, add the link, and lay out the procedure as to the flash sequence so everyone who'd like to give a shot would know what to follow. I know I might be asking much but if you could, I'd appreciate it very much.
[Dell Venue] megaghostgamer:
Not a problem at all! :) I just want to reassure everyone that I'm not going to take responsibility in your tablet being put into some fastboot lockdown or loss of root. I'm uploading what has personally worked for ME.

Alright, now first you're going to need to download the file to your internal/sd card storage on your tablet, (don't be alarmed by it saying v4, i was testing several things) https://drive.google.com/file/d/0BwM2zCxNnCZnTElILUIzOXRMd1E/view .

Next, get into the temp recovery that you had to originally in order to root the tablet using this thread - http://xdaforums.com/android/development/intel-android-devices-root-temp-cwm-t2975096 . The instructions for doing so are on that thread.

Next, you're going to want to direct your tablet into the folder (While you're in the Temp CWM Recovery) in which you downloaded the update. Once you've found it, flash it and reboot.

I want to reassure that the update flashed properly, please post back feedback. I'm avoiding the whole fastboot patch. I removed the lines so it wouldn't touch it. However, I do see a boot.img (kernel) patch in it. For me I do see a ever so slightly increase in performance, mainly multitasking if anything. Dell keeps wanting to notify me that there's an update so I disabled the dell update service to get it to go away.

Best of luck! :)
[Dell Venue] graphdarnell:
Thanks for the instructions. Quick question, however. Do you flash the modified zip first, then allow the OTA to install? Seems from where I stand, if you go with the OTA first, then fastboot would've been locked and you can't flash anything afterwards. But if you do the OTA afterwards, wouldn't it overwrite the modified zip? Am I wrong?

For what it's worth, I've been receiving the OTA notification, but haven't touched it yet for the obvious reason that it would lock fastboot and remove root when applied.
[Dell Venue] SirBeherit:
I just installed OTA on rooted device and everything works :) After that I rooted device again, because its lost after upgrade.
[Dell Venue] megaghostgamer:
From a previous report (not the one before this post), someone stated how they took the ota and it locked their fastboot. If you let the OTA install after the modified zip, it'll flash the fastboot patch. The patch is the same thing as the ota just minus the fastboot. The modified zip does not prevent the original ota from patching your fastboot.
[Dell Venue] graphdarnell:
Thanks for clarifying. I'll give it a shot and will post feedback by this weekend. Take the OTA first, then flash the modified zip.
[Dell Venue] sime23:
Sorry for being lazy, but can you guys please post firmware version you have after updating? Thanks
[Dell Venue] megaghostgamer:
Don't let the ota run lol. It's said to have block the fastboot access. Just use my patch..

IFWI Version - 0005.2235
[Dell Venue] golfyrider:
then idownload and flash it ...... it say .................error code 7
[Dell Venue] megaghostgamer:
try downloading again and flashing again
[Dell Venue] waingro808:
After the latest OTA update, the tablet seems much faster :)
[Dell Venue] graphdarnell:
Sorry for being late in reporting. Funny thing happened. I downloaded the modified zip twice to flash onto the 442 ROM and it failed every time. Out of frustration, I let the thing update to 444 on the OTA just to see what it would cause. Surely enough, Fastboot still works and Root is still there. Right now I have the same IFWI Version as above. So it looks like a hit-or-miss with the OTA.
[Dell Venue] megaghostgamer:
I was already on 4.4.4 when it showed that I had an update, odd. I guess the newest doesn't lock the OTA or it may to some users. I guess more users have to report. Thanks for the feedback!
[Dell Venue] golfyrider:
i load it again

try to flash it in temp CWM

it say error status 7 again
[Dell Venue] megaghostgamer:
Odd. I'll have to look at it when I have more time on my hands. Currently having issues at home and it's not the best time to be messing with updates. I'll check in and out for those that have questions. I'll just mess with the update when things lighten up. Thank you for the feedback! :)
[Dell Venue] AwesomeLewis24:
Thanks mega for supplying the zip. Sigh, everyone is saying how the performance has increased with the latest update and I'm desperate for it. Whenever I try and install the update, it fails because I'm missing "TelephonyProvider.apk", and I've followed through with tons of solutions. This is my last straw, I'll do a full Titanium backup and reflash the OS to install this update. Please Dell, this better be worth it...
[Dell Venue] sime23:
Just to let you people know, after last update IFWI Version - 0005.2235 stays the same as before.

Only kernel version changes to Oct-9. It's a bit odd and hard to distinguish in discussion, so I thought it might help pointing that out here.
