I just purchased a 7840, updated to 5.0.2 and also found that the method from this page does not work.

In short, CWM never loads after the console shows that the T3 trigger method has completed.

Steps to reproduce + terminal output

:

0) Ensure Venue 7840 is updated to 5.0.2 and from Developer options, enable 'USB debugging' and disable 'Verify apps over USB'.

1) Enable unsigned drivers in Windows 8.1

2) Install the ADB Driver from page-2.

3) Download UPDATE-SuperSU-v2.46.zip to the 7840

4) Download IntelAndroid-FBRL-01-17-2015.7z and run launcher.bat as admin

5) Type "ACCEPT" and ensure DEVICE STATUS and DEVICE INFORMATION show relevant info.

6) Type "T3" and hit Enter.

Press any key to continue . . .

7) Before pressing a key to continue, this is what's shown on the 7840's screen:

8) After pressing a key to continue, the terminal returns to the original menu but nothing appears to happen on the 7840's screen as it continues to display as shown in the image above.

9) After waiting 10 minutes, the screen did not change and so I attempted to enter recovery manually by pressing volume-up/down and the power button on "RECOVERY MODE"

Any custom ROM for venue 7 3730 so far?
[Miscellaneous Android Development] social-design-concepts:
Unfortunately until Dell decides to release the dev-edition firmware for the 3730 it isn't possible :( send an email to opensource@dell.com and ask them to be fair to all users and release the dev-edition for the 3730 as they have for all their other Intel android tablets
[Miscellaneous Android Development] dk0r:
While I too am interested in this, the thread is about root via temp recovery, not rom's.

Please keep the thread on topic so those of us subscribed to the thread do not receive further irrelevant update notifications (..like this one I'm posting now).

Put my own fstab in the recovery.zip?

Hi,

the temp CWM starts up on my tablet when using T2, that's great. But it complains about the original.fstab etc. and cannot mount anything. I've unpacked the ramdisk from droidboot.img of my device and could find a file fstab.MBT05A_1 there, which is possibly what CWM needs to work. How can I modify the tool's recovery.zip to use the information included in the device's specific fstab?

Regards,

Maciej
[Miscellaneous Android Development] social-design-concepts:
You simply need to modify the fstab so its compatible for cwm then add it to the recovery.zip in the etc folder
[Miscellaneous Android Development] social-design-concepts:
i haven't got the pics yet but 1 tester just confirmed that the new trigger works to root the Dell Venue 7840 Lollipop release, should have it cleaned up and uploaded for all tomorrow.
[Miscellaneous Android Development] vampirefo:
That's good, is bootloader still locked on 7840?
[Miscellaneous Android Development] social-design-concepts:
Not sure if anybody has tried to roll back to the uos firmware after the lollipop upgrade. If I owned the device I would probably try to build a lollipop compatible boot image with the old image format shouldn't be to hard.

Biggest issue with Intel seems to be the inconsistency with their kernel image packaging
[Miscellaneous Android Development] vampirefo:
All depends on bootloader, if locked you can't flash modified boot.img.

If I own the device I would turn encryption off, but even for that bootloader needs to be unlocked.
[Miscellaneous Android Development] social-design-concepts:
Yeah that's why I would want to build a compatible lollipop boot image for the old 7840 dev-edition bootloader.
[Miscellaneous Android Development] social-design-concepts:
Hopefully this trigger will work for the Nokia N1 also
[Miscellaneous Android Development] vampirefo:
Nextbook Ares 11.6 is becoming poplar at walmart. My guess similar to trigger would be needed for it also.
[Miscellaneous Android Development] social-design-concepts:
Not heard of this one? What are the specs? OK looks interesting falls into my math of $10 a month over the expected life span of the device but man why has Intel dropped to a gig of ram.

[Miscellaneous Android Development] social-design-concepts:
Don't try this with the current tethered cwm launcher. Its more than just a change to the batch file. Changes had to be made to the recovery.trigger binary to allow it to work with out these changes it will continue to loop when starting the recovery.launcher. i'll have the new version up in a few hours so please be patient.

Thanks [MENTION=573077]docmo[/MENTION] for testing if you were one of the three testers i would appreciate it if you didn't share the link or the files. thanks

IntelAndroid-FBRL 05-16-2015 Public Trail Release

i'm not ready to post a full update so i guess you can call this a public trial , there's a few things i wanna fix not related to the 7840 really just a couple things i wanna add for a couple of other things.

IntelAndroid-FBRL-05-16-2015-PTR.7z

one tester reported that on the Dell Venue 7840 that it wouldn't mount the internal sdcard , it's probably an issue with needing a recovery designed for lollipop , but this will still allow you to root.
[Miscellaneous Android Development] olvrick:
Filehost is lagging=(

Unexpected response from the server:
[Miscellaneous Android Development] social-design-concepts:
i gotta run out quick if they are still having issues i'll post some where else they're normally fairly good maybe they are doing updates
[Miscellaneous Android Development] olvrick:
Its ok now, ive mistakely thought that it cant mount sdcard in this release and put supersu into internal memory=)

After launching CWM ive realized that it cant mount internal memory, and everythin is good with mounting external microsd card.
[Miscellaneous Android Development] lasset:
I used trigger T3 and after proccess ending, in fastboot mode I got the message "CMW wating".

What I´m doing wrong? And Thanks for your development.
[Miscellaneous Android Development] vampirefo:
Your data partition is encrypted so, cwm recovery won't be able to mount internal sdcard, external micro sdcard should work just fine.

---------- Post added at 08:03 AM ---------- Previous post was at 07:43 AM ----------

Are you sure it's trigger 3? I haven't even looked at the release but I would assume it would have been trigger 4.

Ok, I just downloaded it and as i said it appears to be T4 or trigger 4 not trigger 3.

T4 . launch using oem stop_partitioning trigger alternate version
if %choice% == T4 set OEMTRIGGER="/system/bin/logcat" &set OEMCMD="stop_partitioning" &set TRIGGER

unroot

For an Update of my Asus Fonepad 8 i need to UNROOT the Device.

Otherwise i have no option to install.

Need help.

SuperSU unroot don't funktion.

Also many other Apps in the PlayStore don't funktion.

For the 2. way my question.

Have anbody a firmware WW-Version for the ASUS Fonepad 8 (FE8030CXG)???

On time there is nothing to download by ASUS Support.
[Miscellaneous Android Development] lasset:
Thank you very much, installation work without problems., once more thanks!
[Miscellaneous Android Development] social-design-concepts:
not sure sorry

Isn't this it ? http://www.asus.com/Tablets/ASUS_Fonepad_8_FE380CG/HelpDesk/

the x at the end of the model i believe from looking at other Asus firmware for months is the model with large storage

so the 8GB EMMC 1 GB of ram would be model FE380CG and the 16Gb EMMC 2GB of RAM would be model FE380CGX
[Miscellaneous Android Development] nudi:
Sorry but No.

This is the older CG Version. I have the CXG Version. On time i don't find a WW-Firmware to download by ASUS support.

---------- Post added at 01:55 PM ---------- Previous post was at 01:54 PM ----------

Sorry but No. My device have also 8GB.

This is the older CG Version. I have the CXG Version. On time i don't find a WW-Firmware to download by ASUS support.
[Miscellaneous Android Development] social-design-concepts:
Read the model wrong sorry.

Asus is probably the best at posting firmware for their devices as long as its not a model sold only through Verizon or TMobile I probably suggest calling Asus support then.

Sorry I can only find the CN firmware for that model
[Miscellaneous Android Development] AxMaster007:
Worked like a champ on my 7840 with Lollipop! Much thanks!
[Miscellaneous Android Development] nudi:
Hy, social-design-concepts

I have to make a rollback (uturn).

First, i download firmware for both versions the CG and CXG. Then i see the firmware is for both good, because the Hardware Version is the same.

It is "K016". Both versions have the same Hardware code.

At next i flash the CG ww-version firmware. I flash it without any problem. After flashing the system make the "update". All is running fine.

At last, because i have a firmware now, root the device.

At last what i wan't to say. the firmware from here:

http://www.asus.com/de/supportonly/ASUS Fonepad 8 (FE380CG)/HelpDesk_Download/

is also good for this hardware:

I was having bootloop of my Zenfone 5, and everytime I tried to flash anything, it will return

E: failed to mount /cache (Invalid argument)

E: Can't mount /cache/recovery/log

E: Can't open /cache/recovery/log

repeatedly...

Tried this triggers as an alternative but no luck to make my phone alive again. Anyone got any idea? Thanks
[Miscellaneous Android Development] social-design-concepts:
Sounds like you'll have to add a recovery.fstab to the recovery.zip for your device , you also have to be more specific I think there is like 3 or 4 Zenfone 5 models.
[Miscellaneous Android Development] johnblackwood:
My Zenfone 5 T00J, WW version.

Do you mean just adding the .fstab into the .zip file?
[Miscellaneous Android Development] social-design-concepts:
You need to reformat the recovery.fstab to be compatible with cwm recovery you can Google examples or I can post a sample after work you'll probably get malformed errors using the factory fstab, it needs tobe named recovery.fstab and placed in the etc/ folder in the recovery.zip
[Miscellaneous Android Development] lamoid:
The same thing has happened to my Dell Venue 8 7000. In the recovery.zip for the temporary CWM recovery found in IntelAndroid-FBRL-05-16-2015-PTR.7z, the /etc folder is empty. How do I construct recovery.fstab?
[Miscellaneous Android Development] social-design-concepts:
The 7840 shouldn't need it , does the recovery seem to loop when loading then eventually settle at the cwm menu with that error? What OS you using?

Hi,

try a test on my new rooted Zenfone 2 but it doenst work, phone reboot into orig. fastboot screen but error was an unknown trigger. Any chance make it usable on Zenfone 2 (ZE551ML)?
[Miscellaneous Android Development] social-design-concepts:
Downloading firmware now I'll see if it can be add can you post screen shots of the command prompt and device when running the triggers
[Miscellaneous Android Development] lamoid:
Upon normal boot, the 7480's screen displays the Dell / Android screen then the Intel Inside screen and just sits there.

If I try to enter recovery from the boot loader I get the Dell / Android Screen then the dead android graphic with the exclamation point in the red triangle.

Later: OK so, I reran the FTBR dated 16 May (IntelAndroid-FBRL-05-16-2015-PTR.7z).

That got me back into the CWM vampire screen where as before it could do almost nothing because of the inability to mount /cache. However I was able to do a factory reset and to get back to where I was before the attempt at rooting.

3741?

DEVICE: Dell Venue 7 3741 on KK 4.4.4 (SIM + WIFI).

I've tried this and I got a fail warning on the batch command with option 3, and a squiggly mess on the device screen. After that I held the power button to reset, it booted back to the normal system, then rebooted and performed what looked like a ROM install (although the prompt was in Chinese, despite being an Australian purchase). After that it rebooted into the normal system again after optimizing all apps (no user data wiped). After a while a Dell notification popped up saying "you need to reboot to continue the update". Doing so returned me to the Chinese install screen, followed by a black text saying "AFU install: BIOS update" (I thought there was no BIOS on these?). After it completed it booted back to the system again with no data wiped.

Has anybody else got a 3741? Are they supported?
[Miscellaneous Android Development] social-design-concepts:
Not sure yet those are brand new and ive only seen it for sale on Dell's AU site ( side note the 3731 was Chinese only ) and some devices do have a bios the telcast x98 has a bios / uefi as well and telcast even supports an windows 8.1 installation on theirs unit.

but could you try again it might of had an ota pending can you post picture of the device screen while running and a screen shot of the tool window , you made sure you have fastboot drivers properly installed?

what was the fail warning ?

i think you had an ota pending cwm would still check for /cache/recovery/command and would execute it if it found it.

and a failed warning like to many links or something along those lines is normal as the first thing that happens is the droidboot / fastboot service is killed so it has no way of getting a return status from the command.
[Miscellaneous Android Development] Blufires:
Thanks for your fast reply.

I've just retried it again using option T3. Fail warning was too many links. This time I waited longer on the squiggly garbled device screen, and CWM booted. I guess I was a bit impatient before.

I can now confirm root works for ES file explorer on 3741.

Android: 4.4.4

IFWI: 5.6.5

BIOS: LW_T7GD2_0.40

Hey mate,

Thanks for your great tool.

I was able to run the recovery and install root via recovery for my tablet. I was using option T1 and was working perfect.

My tablet is a Chinese one with an Intel Z2580 processor. Main known model is Teclast P89 mini with many different clones (Explay i1 / Vido M6 / Allview Viva i8 / FreeTAB 7800 )

Now I want you help.

I had modified the recovery.fstab acording my tablet. https://www.dropbox.com/s/mtpm5ds71bdkksx/recovery.fstab?dl=0

I was able to make a back-up with the recovery but only for cache/data/system. How to back-up the rest (like boot.img and other things, especially for warranty/brick purpose).

The structure is so

https://www.dropbox.com/s/0t0u82n4abgo336/partitions.txt?dl=0

https://www.dropbox.com/s/tyvmqdluw25flih/parted.txt?dl=0

On several forum I had seen original and custom roms but all use Intel Phone Flash Tool to flash them, but I think is a bit risky and it will change a lot the tablet and cannot be restored factory, because for my type I don't have a factory rom (Allview Viva i8).

I will like to use more traditional flashing method via recovery with zip files.

Now i have root, how do I can extract all the other necessary files for porting roms.

Regards

Thanks again for the tool.

Respect!
[Miscellaneous Android Development] social-design-concepts:
I'll be posting more information after the holidays their is a few different ways those images are stored depending on the type of device and is being looked into. For now the biggest suggestion I can make is to make sure to capture ota updates they generally contain important files needed for unbricking. As for custom ROMs so far its not possible for devices with locked boot loads check back after Christmas the reserved post should be updated sometime shortly after.

[Miscellaneous Android Development] vampirefo:
What version OS are you using? Have you downloaded the latest version of your tablet's firmware? The additional files you seek will be in the firmware you download.

All that is needed to be backed up by CWM recovery is system and data, as these partitions, change the rest of the tablet's partitions, don't change unless you have an unlocked bootloader, and made the changes, ie added custom recovery, or boot.img.

OK,

I have downloaded several firmwares but I'm able to boot just those that are 4.2.2

The newer version available officially a 4.4.2 I'm not able to boot those. I've try to flash also the boot.img available in the zip file, but without success, still no boot.

At very beginning I have made a backup of all the partitions via did if=... but I don't know how to flash them back in case of some trouble. Can some help with that.

With this recovery I'm able to make a backup of data/cache/system, but not the recovery and boot.img.

The partitions structure you can see them a few post back. Any ideas will help.

Just got back from holiday stuff I'll be updating the thread to night adding a zip to run from the recovery that will dump the boot recovery and fastboot images as well as an update to the recovery launcher that will automatically generate the recovery.fstab

If device has an official boot it should flash but you need to remember to wipe data as well as the bootloader / firmware ( ifwi / dnx )may need to be updated to use the updated bootstub ( second stage bootloader ) that the KitKat images use.
