Don't give assumed information. Do some research first.

Are you telling me what is and what is not......if TWRP was not patched to use ubifs, and if i didn't test the functionality of my recovery myself, do you think i would share it.

TWRP has been fully patched to use ubifs filesystem and now has full support for mtk devices since 2014, thanks to some devs, with support for things like nonstandard touch interfaces (flip screen, swap screens), and backup of special mtk partitions.

Our device has a layout of (swapXY----Flip-Y) which is what i discovered and is why iv been able to now succesfully port a touch recovery, so next time before giving assumed information, go do your research......:cool::cool::cool::cool:

so @george676 what do you mean

by ""and backup of special mtk partitions.""` Posted by [MENTION=5873934]george676[/MENTION]. is that a hint at a full spflashtools flash able ROM, or would it require a halfbricked device : ie a recovery bootable device, to re-flash,, im still shooting for the ever elusive full recovery from total brick,, mainly because a fresh device is technically a brick when its first made then its flashed into a working device ... and .... .. .. though i would bring it up... ... ..

Guys, codelover & i have prepared another test ROM, which we hope can be used to revive bricked devices.

Earlier uploaded files were merely a pure dump without any touch, while this one has been processed.

This ROM has not been tested on fully working device and we hope those with bricked device can test it first.

To try, load the scatter and choose "Format All + Download" and connect your device while powered off.

You can use the SP Flash Tool that i provided earlier.

If you were lucky you might atleast be able to enter stock recovery, perform a factory reset before running the rom.

Ok i got this and have been trying to root it since last night. i have tried 2 differnt pc's one 32 bit windows 7 and the other 64 bit windows 7 and kingo didnt work for me on either one tried everything. even updated android sdk and usb driver files with no help at all.

then i tried this IROOT which is the first time i ever heard of it... the apk version didnt seem to work but the windows one did. it added a chinese Superuser and i switched to SUPERsu. If kingo isnt working for you, I vouche for the Iroot. it worked for me.

oh and i have like 10 rooted androids so im not a newbie, just seemed to have HTC drivers defaulting for this tablet.

So maybe with some luck there will be custom recovery & maybe oc kernel? Hopefully lol. Would be nice to have performance tweeks as well?
[General Questions and Answers] TripFX:
almost got twrp 2.8.1.0 working once i do then hopefully i can start working on a better kernel. like others have pointed out. rca advertises as 1.4ghz real is 1.3ghz and according to mediatek our cpu should actually be 1.5ghz. However being this is a cheap tablet they used a weaker battery and underclocked it to keep battery life up. You can keep up with progress on twrp here note the main op is not mine and you will find my posts towards the end. If you got the know how and better skill then me feel free to do it and share. I will make an official op for this tablet once i get some things working properly other than root.

UPDATE yes it is a quad not a dual core it has mt8127

The viewing angle is horrendous. You have to be dead on to see BUT the picture quality is good for a $30 tablet. Kids won't be bothered by it since they plant their faces directly to the screen.

The backup was made with spft ( [MENTION=6253458]synius[/MENTION] Thanks for supplying the backup to be diced ) and then it was diced up to make what was released. :)

[MENTION=5211506]leetree2001[/MENTION]

No its not even look at other firmwares with same soc preloader is only 1xxKB's. You must be thinking of the partition size which is where your probably getting the 16MB from.;)
[General Questions and Answers] synius:
the read back from my device is everything from start address 0x00000000 until 0x000000006800000 which according the the devices dumchar_info is the last partition start address before bmtpool (userdata) this could be wrong because of the updates vampire summited

i brought this issue up before why does the update.zip scatter files dont match any of the mtd tables or dumchar_info file i think this should be taken into consideration if i should do another readback with a different end address from the V2 scatter the 0xffff address of bmtpool.

TripFX let me know what you think about that?

just a thought....
[General Questions and Answers] TripFX:
correction codelover used my backup files we made for the zip not yours, he used yours for reference, but still thank you for helping thou. Scatter is on v3 now. [MENTION=2472806]vampirefo[/MENTION] mentioned his partitions was different then ours so thats probably why fhey dont align. Sorry i don't feel like going back thru the posts to find exactly what he said but im sure you can easily find it or perhaps he may post a better explanation. You'r free to try making another backup or w/e you want as its your tablet. But as of right now we don't need anything other than bricked/bootloop testers to report back. If there is something else we need I will message you or post pending on what is needed if and when that time comes.

copy

how can i download a copy my working rct6773w22 i flashed clockwork recovery with v2 scatter and i cant get a full backup because it cant mount /system
[General Questions and Answers] synius:
your misunderstanding yes vampires partitions are different but im talking bout the signed rca updates that contain the source of our scatters. which means all 3 scatter files are identical in regards to start addresses. where as the on board device mtd table and dumchar_info have different start addresses.

should i have used the start addresses of the scatter file for the end address for readback or the dumchar_info like i did?
[General Questions and Answers] TripFX:
please read the entire thread and you will have your ansere as it has been mentioned multiple times.

Ok now I understand the question better. let's see if my wording is correct, if not terribly sorry.

So the question your asking what you should have used for the end address readback. 1st dont use the dumchar_info as the start address are completely wrong and look like this

0x00000000

0x00000001

0x00000002

so the scatter file has the real start address. now looking at the scatter file say you wanted to do a readback to just before userdata as it gets wiped anyways when you do a factory reset i would use the start address of userdata for the end address which should be 0x81000000 and if you wanted to do userdata as well you would use the BMTPOOL start address. Hope that clarifies it better for you. also do not use sparse for readback

I stated the problem wrong before the tablet boots to rca dogs then black screen like there is no os
[General Questions and Answers] synius:
So I assume you flashed. The new Files and scatter if not, try updated files they include all partition files.. Then try to boot

If it doesn't boot up still then we check recovery

Push hold power + vol up button hold it until tablet shutdown and reboots

This should put you in standard recovery

Try factory reset then reboot system

I just wanna see if this feature works

If it does great. If it doesnt then there's a problem

If it loads recovery there is hope flashing cwm recovery and then restoring from backup would be the next phase if the flash didn't fix it

But as I saw in previous post you used v2 scatter. There is now a v3 with partition files try these and report back

If anyone can offer any other information that I may b incorrect about please feel free

Please read what he actually said and what he actually referred you to before asking useless questions plz.

He refered you to this

"This link is for latest v3 complete ROM dump provided to us from tripfx and codelover"

and not his which says

"ive pulled a new rom it contains 2.17 gig ill upload it to mediafire link already provided"

He did not refer you to his as his is completely useless as is. It would need diced into different files for different partitions. His may include userdata which is nothing YOU actually need as it would contain his pics, apps, vids, music, etc. He referred you to mine as it is already diced for the the partitions and contains a blank userdata which as it is when you first turn it on from a factory wipe thus the reasoning why mine is smaller. Also note that he mentioned his was mediafire link not google.

[General Questions and Answers] synius:
to clairify the 2.17 gig readback is a pull according to the v3 scatter upto userdata. i figured a correct pull shouldve been the reference instead what i provided before may have been incomplete due to the start addresses from dumchar

THIS was entirely for tripfx and codelover.. no one else should download it unless the plan on dicing and producing there own stock rom.... enough said.

so its a working rom thats great news, seeing as he got language setup woot

no touch response should be able to be fixed quite easily.

altho why wouldnt it work is the question really.
[General Questions and Answers] acejay3200:
yes the rom boots you guys are good
[General Questions and Answers] TripFX:
So to clarify. The method i provided worked? was it just delayed touch from first boot or was there something else? If that is the case and your tablet is fully working what i would recommend is to use spft to flash the test cwm. then update supersu, then flash back stock or just leave it as cwm if you dont use recovery least until we get a fully functional recovery. you should be able to update su binary without cwm but if not the use cwm to update binary and do nothing else with recovery. if you want to wipe davlik-cache you could use Performance Control as there is an option in there to do it as well as freeze bloatware that you dont need if you want to be able to do ota updates still but ota also requires stock recovery.
