I just compile non touch for my phone, really need to get the dumchar_info for you device.

adb pull /proc/dumchar_info

I will upload a test you can flash through your cw to see what it looks like.
[Android General] smartmanvartan:
jerryvail posted it for you earlier
[Android General] vampirefo:
Yes i can't use a pic, I need text file.
[Android General] smartmanvartan:
How do you get the file with terminal emulator?
[Android General] vampirefo:
if rooted and have file manager just navigate to it.

with terminal

su

cp /proc/dumchar_info /sdcard/proc/dumchar_info

I have just now started backup with cwm on my phone, once done will test restore.
[Android General] smartmanvartan:
Give me five minutes... Rooting now
[Android General] vampirefo:
here is a recovery to test, built from my phone specs, most likely will work on your tablet.

testing now... so far so good... testing backup restore
[Android General] vampirefo:
Default backup and restore worked for me, I am going to compile another one with your tablet's specs.
[Android General] smartmanvartan:
Backup restore was successful! Nice touch son the carliv options!
[Android General] smartmanvartan:
What device did you compile this one for? it seems to work perfectly...
[Android General] vampirefo:
It's built for my blu energy x plus phone, mount points are same as your tablet, boot, recovery same size, so I figure should work on your tablet.
[Android General] smartmanvartan:
Kernel too? Or did you use the one from the last time ?
[Android General] vampirefo:
Kernel is from your device, so is ramdisk, I added cwm to your device stock recovery.
[Android General] NepoRood:
I figured you'd pull it off before the rest of us, thanks man.

[Android General] Jacube22:
When you flash the unlocked bootloader, do you have to flash it with the whole firmware? or do you just flash the bootloader?
[Android General] jerryvail35:
just the bootloader
[Android General] smartmanvartan:
Flash the bootloader alone... What firmware are you running right now anyways?
[Android General] Jacube22:
1.9.1 V32
[Android General] smartmanvartan:
Oh yeah you be careful. You have that link to the firmware right. Just flash the altered bootloader and see if it boots. If it does then proceed to unlocking it. If not then you have the 1.9.1 firmware link as a backup
[Android General] Jacube22:
Ok. (I'm doing it tomorrow anyways)
[Android General] Jacube22:
Bootlooped it again :(
[Android General] smartmanvartan:
You flashed the bootloader and it bootlooped?
[Android General] Jacube22:
No I just bootlooped while messing around with Xposed
[Android General] smartmanvartan:
Oh OK .. No stress you got that firmware ;)
[Android General] smartmanvartan:
Did you receive your USB cable yet?
[Android General] Jacube22:
Is it ok if I flash the altered bootloader with the firmware, or do i have to flash it later?
[Android General] jerryvail35:
I would start with your firmware first then try the bootloader since you on a different version than us.
[Android General] Jacube22:
I know this sounds like a dumb question, but how do you flash just the bootloader?

do you just grab the bootloader and scatter file?
[Android General] smartmanvartan:
Just load the scatter file but take( or copy) the scatter file or off the folder where it's at. When you load the scatter file there will be nothing checked. Check the "uboot" option and on the right in that line, click and select the modified bootloader. Then press download and plug your phone in the pc.
[Android General] Jacube22:
Do I have to rename the bootloader file? (to lk.bin instead of lk_patched.bin)
[Android General] Spartan Legionnaire:
I ordered just a micro usb to usb type A adapter, it should work I think, I didn't tried yet
[Android General] smartmanvartan:
No it doesn't matter

Edit: sorry the no it doesn't matter was for Jacube22

The USB micro adapter should work.. It's what I use.:)
[Android General] Spartan Legionnaire:
I will try just to send some files to the tablet. When I have more time I will root also
[Android General] Jacube22:
Not Working...

It just shows a black screen.

It looks like it is trying to boot, but then it turns off.

Reflashing stock firmware now...
[Android General] smartmanvartan:
The transfer of files won't work... There is no file transferring capabilities. But the USB adapter you ordered should work for fastboot and preloader mode.

---------- Post added at 07:23 PM ---------- Previous post was at 07:01 PM ----------

OK once again you can just flash the bootloader... That's too bad...
[Android General] Jacube22:
Yep... Guess we gotta get this to work on my firmware too now. (or at least try)

I'll try to patch my bootloader tomorrow.
[Android General] Spartan Legionnaire:
Ahh, OK. I will try when I have some time :D thanks again
[Android General] Bogram:
Good luck, I hope it works. If the button check code is the same, the patch I posted earlier should work. HxD is the hex editor I used to test that patch on a couple of lk.bin versions (v66, v72), if you're on windows and don't have one it's small/free.

Reposting for convenience:
[Android General] Jacube22:
Bootloader

I have edited the bootloader:, flashing it now...

It Booted! Will now attempt to unlock...

Something happened.. I pushed some buttons once it got to the fastboot unlock screen, and then hit the reset button.

The android robot then showed up for about 10 seconds, then it rebooted again.

It bootlooped... Reflashing stock

Second Try:

after trying it again, it did unlock, and it booted just fine.

Probably failed the first time because i didn't do the fastboot oem lks command first.

And Here is another somewhat related question:

Once I try to flash the recovery, If it bootloops, do i just have to flash the recovery partition, or do I have to keep flashing the whole firmware each time...
[Android General] smartmanvartan:
the recovery wont boot on your .9... hang tight ill hook you up

see if it works .. if not ill fix it when i get back later tonight
[Android General] Jacube22:
It Will show up, but the recovery just gets replaced when the system boots normally.
[Android General] smartmanvartan:
Did you boot system? System reflashes stock recovery...
[Android General] Snigglez:
WoRKED!!

Flashed with Rashr & it took (running v.32 1.9.1); thank you - this is awesome:laugh:
[Android General] Jacube22:
CSpan Confirmed

Works for me too.
[Android General] smartmanvartan:
Awesome man! glad to hear. There is a file in the system folder called "recovery-from-boot.p"... Delete it! At some random point it will flash stock recovery all by itself and replace cwm. Can you post a link to your modified bootloader for other x.9.x users?
[Android General] jerryvail35:
it almost seems time to start another thread for these devices ,since now that we have root,unlocked bl and cwm for this device for almost all of the versions.
[Android General] smartmanvartan:
I was seriously going to post the same thing...
[Android General] jerryvail35:
Well! Between you,bogram,vampirefo and csla. Someone has to.
[Android General] Snigglez:
i am unsure what you are asking; you see, im unable to utilize sp flash tools on my native debian desktop, nor on vm windows. All i did was take the cwm image linked, change its name to 'recovery.img' - removing the stock image from /system & replacing it with the new image (making sure permissions were kinked); then just flashed it as a recovery image with Rashr.

Yes, i realize i am a n00b skeez-hacking in the halls of Craftsmen, and I share my discovery most humbly & with gratitude & respect for the efforts, time & labour of those with whom I now enjoy guidance & company - thus, please let me know how I may be of any help, although my methods and background are different.

It is well to conclude that indeed, a successful backup, wipe (reset, cache and davlik) & restore was performed. There is Joy!
[Android General] smartmanvartan:
@vampirefo @Bogram @ewilley2008 @NepoRood @Jacube22 you guys ok with me making a new thread with all of this organized and your contributions listed with links?

---------- Post added at 01:04 AM ---------- Previous post was at 12:41 AM ----------

I'm sorry.. sometimes I'm on my phone and i mix up the replies.... @Snigglez I'm glad you got the recovery working on your tablet. take note of the file i mentioned to delete in the /system folder or the recovery will be replaced with stock when you reboot. @Jacube22 I'm really glad you got the bl mod to work on your bl. the question about linking the modified bl was meant for you... Also to answer your earlier question, you can flash anything individually with sp flash tools and a detached scatter file.
[Android General] Spartan Legionnaire:
Can you @ me there to know about the new post?
[Android General] smartmanvartan:
For sure. And I would post a link to that thread here as well.
[Android General] Bogram:
I'm fine with that.
[Android General] NepoRood:
It needs to be done, maybe even zip everything up and put it into one download (well, one for each version)

[Android General] jerryvail35:
quick question. any one here have the new-ish htc desire 626s?(new project)
[Android General] Snigglez:
I'm here too - day off - yay! I want to port PACrom or something to this device; I have now a male to male USB cable, but my laptop isn't recognizing the device at all by the myriad methods presented in this thread, yet it will recognize the device with the standard male to mini-male USB. I'm going to make my own.

Btw, is there any cool 'in-slang' for these cables? Maybe something like a "Bath-House-Cable" or "Phil & Fat-Franky Cable" for the hard to find 'male-to-male'? Perhaps regarding the standard yet unworkable 'male-to-mini-male?' could be dubbed the "Eros-Cable," or "Forbidden Cable"? :)

I love you guys - thank you for everything - this thread has proved a great introduction to XDA, and I've enjoyed catching up with developments posted here everyday.

I've started working on the Maven Pro (RCT6213W87DK) to see if all this stuff will apply to it as well (root method works).

Plus side, the Maven has ADB access, so I may be able to pull files from it to build for the Viking, that's what I'm hoping anyway ;)

i call mine (jerry rigged) because its home made.
[Android General] Bogram:
I've been messing around with the usb stuff and thought I'd dump what I'd figured out so far. (Or at least what I think I've figured out.) Sorry this is probably going to be a bit of a ramble.

According to what I can glean from poking at /sys/devices/platform and other places as well as digging in android kernel source for other mtk chips, the side big usb port we use for the flash tool and for usb devices is in OTG mode but is stuck as host either via driver compile time options or possibly the OTG id pin is internally shorted but I haven't taken my tablet apart. (The big usb A connector lacks the ID pin a micro would have but the chip would likely have the pin) If we could get it into client/peripheral mode it looks like the necessary stuff is present for it to function with adb/mtp/ptp/mass storage/etc. The side port has 5 little contact pads recessed in front of the 4 usb pins that I couldn't find any info on. From the looks of it the driver has most if not all the debug/configfs stuff disabled.

I think the keyboard USB_POGO port is considered separate, it has it's own entry under /sys/devices/platform, a different bus number and looks like it's probably non-OTG host mode only but I haven't successfully hooked anything up to it besides the keyboard. I took the keyboard's connector apart but the ribbon cable is soldered to the pins so I couldn't hook my test leads there.

Even if we could find a kernel module that would work with usb the kernel seems to have been compiled with external module support disabled and no /proc/config.gz support. I've been trying to find tablets with the same specs to try kernels from but I haven't had any luck, but there are a few that may be similar.

[MENTION=4666511]smartmanvartan[/MENTION], I've attached a signed driver I got online. (The preloader driver is the CDC one.)

They're the ones I've been using because Microsoft made test mode still need a signature on windows 10 and I didn't want to have to go through the reboot menu every time I wanted to use the flash tool. The signer is MS so they should be trustworthy.
[Android General] NepoRood:
A "Jerry Rig", or just a "Jerry" works for me, lol. EG: Make sure you got a "Jerry" cable before you flash with the SPFT...

So, I managed to unlock the bootloader on the Maven by using the [MENTION=7182821]Bogram[/MENTION] patch (had to patch the kernel that came with the tablet, ours didn't work) and now am working on the recovery (ours don't work there either, :( ) But, since the BL patch worked, I think I can patch the CWM recovery that [MENTION=2472806]vampirefo[/MENTION] made, as well (hoping a swap out of kernels will work)

Peace Folks, Hopefully we'll port a ROM Soon!

Nepo

---------- Post added at 05:30 PM ---------- Previous post was at 04:40 PM ----------

Success!!

I've managed to patch the recovery to work, funny it's in "landscape" mode on the Maven, but not the Viking. Anywho, as far as the Maven is concerned, the bootloader is unlocked and the recovery works (now, after testing) I'm gonna post a new thread that's "device specific", but I'm gonna need some stuff from this thread to give a proper guide. [MENTION=4666511]smartmanvartan[/MENTION], [MENTION=7182821]Bogram[/MENTION], [MENTION=2472806]vampirefo[/MENTION], I'm gonna need to reference your past posts, if it ain't cool, let me know, either here, or via PM
[Android General] jerryvail35:
did kingroot and supersu swap work as well?
[Android General] smartmanvartan:
ok so i finished the new thread... let me know if there is any thing i should change. also the recoveries i edited them so they will backup nvram if you want to reflash. for the guys on x.9.x, i have a newer firmware posted there as well if you want to try it.
[Android General] NepoRood:
Yes, it did. It's almost the same tablet, just a little bigger, 11" screen (1366x768) and running the x.9.x version of firmware.

Im trying to do the same thing to get magic twrp to work. I've been fighting it for two days and it's not working.

I actually forgot how to disable UAC for a second.. :silly:
[Android General] Jacube22:
White screen

I got Magic TWRP to work, but when it flashed the recovery, it shows up as a white screen as soon as I turn it on. So no help there :(

Will Retry...

Try 2: Same result. But in the log I realized it flashed it in the wrong place. So This time, I will Retry using fastboot to flash the recovery.

Try 7: After multiple attempts at getting this to work, it ain't working. Guess that was a failed experiment...

On to other stuff.
[Android General] NepoRood:
White screen tends to indicate that the recovery is too big, it should be 6mb or less to fit :)
[Android General] smartmanvartan:

Progress and Regress, the past few days...

Using CM12.1 I managed to build Cyanogen Simple Recovery from source for this tablet (pics attached). Although it's nice looking, it's really not worth much (ie: can't do Nandroid backups, hence the name). But, the point is: I built it from source, and it WORKS! lol, I thought that some progress in the right direction, so went back to trying to compile TWRP.

After a lot of compiling and a lot of flashing, I've managed to get my tablet to only boot into recovery :confused: I've flashed every original recovery file I have, including stock, but when I turn it on, it goes straight to recovery. I've restored all 3 of my backups, and still nothing. I'm going to try a few more things, if all else fails, I will flash the whole tablet back to stock (one version or other, lol)

Anyway, just taking a small break, and thought I would post.

access is restricted...lol ... not having much luck today.. i requested access

Very cool... I.m do for a reformat and install on my system... gonna go dual boot and install mint or ubuntu and maybe take a swing at building from source...
[Android General] NepoRood:
Be forewarned, it's time consuming, lol Takes me a few hours to download the source (CM or OMNI), not long to compile recovery, after the first time. First compile is slower, took my machine (duel core, 4Gb ram) 25 minutes, 2nd and onward averages between 8 and 11 minutes, unless you change to a different device, lol, then it starts over.

I compiled a rom only once, just to see if it would work, took a little over 12 1/2 hours, I didn't think it was EVER gonna stop, lol

Let me know when you get setup, I've done alot of work you don't need to do, and I'll share it with you to save some time. I'm using Ubuntu 14.04 LTS, but thinking about upgrading to next version. Whatever you choose, we should still be able to work together over git, just get with me before you set up your build environment and do a repo sync ;)

Best of Luck,

Unless I missed something in the fs for the usb driver to force modes I think I'm as far as I can go on the usb investigation without opening up the tablet to look at chip numbers & try to see if the otg ID pin is present/shorted.

I've made a patcher for lk.bin so that people who want/have a different lk version (so long as the code that gets replaced is the same) don't need a hex editor, it's attached below.
