apprently i was tired while editting, i made an error and never changed the cache to ubi_img which i just updated v4.1 http://www.mediafire.com/view/3q5bma2z1pmkqo8/MT8127_Android_scatter_RCA_V4.1.txt

sorry acejay please try once more and repost mtdinfo and mount

vampire shouldnt that mount cache for mtd17 and mtd21 like userdata and system are ubi_img

if that works the partitions are setup and its only a matter of fixing userdata

I suspect it was created because cache is also suppose to have a ubifs partition like system and usrdata have 2 different partitions and when it couldn't detect the cache ubi_img type partition due to type, to put there as mtd21 and with the userdata partition size it just partitioned it as fat system and was never mounted

Just seemed to make sense that it may just be a scatter issue
[General Questions and Answers] acejay3200:
this is with 4.1 scatter that i downloaded today
[General Questions and Answers] synius:
Good new is cache is where it is suppose to be minus that fat partition

( did your storage amount change any in settings storage?

one problem fixed
[General Questions and Answers] acejay3200:
no change in storage space
[General Questions and Answers] synius:
lets give it one more shot please

http://www.mediafire.com/view/3q5bma2z1pmkqo8/MT8127_Android_scatter_RCA_V4.2.txt ( updated bmtpool to test out 0x00000000 start address ) and renamed it sys22 as sys19 thru 21 are system cache userdata

hopfully this should fix it

trying to weive out where that fat partition is coming from im thinking its bmtpool reserving the rest of partition after 0x0000ffff

and post mtdinfo we got cache to mount so im done with that mount.txt
[General Questions and Answers] synius:
Do u see anything off vampire
[General Questions and Answers] vampirefo:
The fat partition is throwing me off, you got his cache working which is great. When I add the partition totals up, that makes the fat partition his internal sdcard, which is supposed to be added to his data partition.

How the internal sdcard and data partition split is beyond me, I think I can put together a tool to reclaim the space, if he can adb via cwm recovery.
[General Questions and Answers] acejay3200:
i can adb with cwm
[General Questions and Answers] nathanski:
?

could you try....

run the spflashtool with no sdcard in ? new scatter, full/format, and no sd would that not correct the missformat slash error-full mounting....
[General Questions and Answers] synius:
Me neither I'm guessing userdata partition could it be the image itself its flashing causing the split what if we set it in scatter that it doesnt need to flash that image but flash the partition by itself. I say that cause the usrdata file image is 1.2 gigs and even with the partition size set its ignoring it, and looks like it flashes the image and doesn't expand the space

Worth a shot?
[General Questions and Answers] TripFX:
codelover is thinking scatter files need to be fixed for both v31 and v38 variants.

As far as the oc goes. i found a Chinese flashable oc with app for a MTK6589/T soc. The problem with it is one its in Chinese which most people including my self cant read. I've already finished translating it all completely to English the app and config files. Another issue is the config for there's doesn't even touch the voltage settings. So currently I am putting all the info for our soc+voltage settings.

On another note. TWRP seems to be ready atleast the v38 variant is for sure as i am currently running it and took the risk of brick to get ubi formatting working.(Thanks to [MENTION=4893922]codelover[/MENTION] for his awesome coding skills) I believe the v31 might be ready as well. I choose not to release yet as there are somethings that are still some things that need fixed first such as scatterfile and v31 rom. Once we have verified that both known variants scatter files and pre-rooted roms work a new op will be made consisting of everything for our model tabs. As the original op that we are using now would make it hard for others to find as it was just a question about how to root. I will post link to it here when that time comes. The new op will consist known working root tool that gives you supersu (kingo) for those with already working non rooted tabs, as well as prerooted stock roms for those that are already bricked due to the bad updates rca did.,scatter files, twrp, spft tool+drivers for both windows and linux and lastly the oc.zip which may be posted at the same time or shortly after depending on how its going. Including some guides for new people ;)

[MENTION=6253458]synius[/MENTION] instead of the stock rom leave it rooted but use supersu instead of the Chinese based superuser.

Lastly I would like to thank the following people for helping us test (when needed), trying to help, giving feedback and your time in no particular order. [MENTION=6253458]synius[/MENTION] [MENTION=6315294]nathanski[/MENTION] [MENTION=2472806]vampirefo[/MENTION] without your help we may have never learned that there is 2 known variants for our tabs nor be as close to as we are now to having support for a tablet that prolly wouldn't have never had it being its such a cheap tab. So thank you and lets keep it up.
[General Questions and Answers] synius:
Well I've already unrooted and such having trouble switching back to supersu now stock ROM is already uploaded its using kinguser its in English but it works for purpose
[General Questions and Answers] vampirefo:
I need you use adb and get me this info.

adb shell ubinfo -a > ubinfo.txt

Upload this file, my tool needs to know what ubi number to delete, and how much data your partition will hold on your tablet.
[General Questions and Answers] synius:
if your attempt fails

remove userdata.img from folder

load this scatter ( http://www.mediafire.com/view/3q5bma2z1pmkqo8/MT8127_Android_scatter_RCA_V4.3.txt )

full format + download

this scatter should partition the whole userdata by itself full size and not flash the image
[General Questions and Answers] acejay3200:
ubiinfo didnt work tried 4 times removed userdata.img loaded v4.3 scatter formatted all and flashed got total space 8.00gb firmware 2.48gb available space 5.43gb
[General Questions and Answers] synius:
btw only 1 i --> ubinfo -a > file.txt

VIOLA SIR you are very welcome and please do continue to test and play with it glad we figure out the scatter issue

the 2 issues fix on acejay device were as follows cache's partition type is UBI_IMG and

userdata's problem was the file it was trying to flash (changed scatter to only place partition and not download the usrdata.img file and gave it the dumchar_info partition size from my device)

nothing like trial and error and just a hunch

(updated)

i do believe scatter 4.3 is correct now for v31-1.10.0

i also think i can modifie the v38 scatter for cache and userdata also

[MENTION=2472806]vampirefo[/MENTION]

[MENTION=2670928]TripFX[/MENTION] your using v38 right?

could u get me

mtdinfo -a

dumchar_info

just need the values for v38 revision to make sure the total adds up

Also slightly confused nathanski device didn't suffer those errors like acejay with an incorrect scatter
[General Questions and Answers] TripFX:
acejay flashed v38 instead of v31 first time which is what prolly caused more problems unlike nathanski. yes i have the v38 and below are the files you requested
[General Questions and Answers] synius:
this is the v38 scatter with the exact changes made to v31 for cache and userdata with the size adjustment for v38

My tablet is still bootlooping. If I try to turn it on when it isn't charging it shows low battery then turns off, but when it is charging is starts bootlooping right away and I can't do anything about it. No matter how much I let it charge when I unplug it it says low battery. I can't boot into recovery or fastboot.
[General Questions and Answers] TripFX:
sounds like a bad battery. You could try pressing the hardware button "reset" and hold it for a few secs. while holding press and hold the power button. then let go of the reset but keep holding the power button until it turns off.
[General Questions and Answers] synius:
After pluggin in Have you tried holding pwr and vol + while powering on it'll shutdown while you hold it, keep holding it, it'll boot up and should jump to recovery, the usb cord will tether power if it is a bad battery but it should be able to go to recovery

I tried that. It didn't work.

Can't wait to get my new laptop in! This is great news! My daughters tab bricked 2 days ago when she took an ota update, I can get into stock recovery still so its all good, now that we have TWRP & stock rooted rom! Nice work guys, thanks to all of you, testers as well! Awesome!
[General Questions and Answers] TripFX:
EDIT:

Could You

1. Identify your tab

2. Flash TWRP for your tab variant after identifying if its v31 or v38.

3. Backup /cache partition and send to me before Factory Reset

4. Wait further instructions if fails

[General Questions and Answers] bftiedt:
I can confirm iroot does work. I couldnt get any other method to work bht iroot. Everything is in chinese so you really have no idea if you are doimg the right thing or not but in the end i had root.

It installs a chinese verxion of super su that i had to freeze with titanium back up then uninstall via TB. Other than that no issues what so ever.
[General Questions and Answers] TripFX:
no i got touch squared away and am able to get twrp to work(partially) i am fairly certain that the issue can be resolved if someone can figure a way out to unlock the bootloader. Im not that skilled in android/linux to do it my self. i tried reverting back to stock recovery so i could do the system update (1.3.1) but it just kept freezing during the update. even after doing a factory reset. My main reason for getting twrp to work is 1 i like it better then cwm and 2. i hate the fact that MediaTek says our cpus factory from them is 1.5ghz, RCA advertises it at 1.4ghz and when in fact they have it at 1.3ghz so i wanted to make an updated kernel with MediaTeks specs are. i could care less about losing a little extra battery life. So i just gave up.
[General Questions and Answers] jediempress:
I bought one of these last Thursday night during Walmarts pre Black Friday special. I was able to root using Kingo. It took me a little bit to find the developer tools because they are hidden. Tapping on the kernal information about 5 times unlocked it. After that I was able to put it in USB debugging mode and root.
[General Questions and Answers] bradbarber35:
Has anybody got this tablet to do the firmware update? Been trying to update it to 1.3.1 and every time I do it reboots into recovery and gets halfway through and then says error. If anybody has the update could you post it here so I can try to update from sdcard in recovery maybe?

did you do anything to your tablet such as trying recoveries or anything? i had 2 of these but 1 wouldn't update while the other did just fine.
[General Questions and Answers] Asadullah:
If you have root then you should be able to get it from the /cache ....area using es file explorer then copy it to an external sdcard.

If anyone gets this please upload it. Me being lazy installed ubuntu and used some tools to make an insecure boot.img flashed it and it soft bricked my device. LOL may look into the return policy. on a side note bootloader mode doesn't work correctly it says it flashes but it doesn't really and I haven't been able to find an sbf tools that work with the tablet.
[General Questions and Answers] bradbarber35:
No haven't tried any recoveries at all. I know xposed sometimes causes issues with updates and I even tried uninstalling that and still won't update. I can't download the update just fine but once it reboots into stock recovery, it installs about half way through and then pops up with the android and says error :(
[General Questions and Answers] TripFX:
my guess we both got a defected devices.
[General Questions and Answers] Asadullah:
I just found a walmart that still had around ten of these in stock so I went to exchange it. I had it in my hand and was a couple minutes from getting my new tablet and then ....... "hold on a minute sir I'll be right back" five minutes later " I'm sorry sir but they are recalling this model and I can't sell or exchange this but I can give you a refund". In my mind I yelled "FUUUUUUUUUUUUUUUUDDDGG". Now I guess I'll get something else. Happy hacking.
[General Questions and Answers] wilmafingerdo:
Updating

I used KingoRoot to root the device as described in this thread. When I got notified of the system update, I delayed it, turned off the Xposed framework, UNROOTED with Kingo, ran the update, and it worked. I had a MicroSD card in the slot that was mounted as well (I don't know if that makes a difference). After update, I re-ran kingo and re-rooted, then re-enabled the Xposed framework. Chrome browser got whacked out, I had to delete all its data, remove the app and re-install Chrome.

I haven't been able to get a custom boot animation to work, I have tried modifying a bootanimation.zip (attached) to match the 640x1024 screen resolution, but it did not load during boot. I tried manually going into the filesystem and placing the file with the correct permissions with a root explorer, but the animation never showed up. I also tried some apps that do this process for you, but they did not work either. One of them modified the animation to 640x1023 and it did not work either. The file bootanimation.zip goes into \system\media as far as I can tell.

For a $30 tablet, its actually not bad besides the screen!

Sorry for the n00bish question (I'm more of a phone person). But with this new stock and recovery and everything, is it now doable / feasible / recommended at all to convert from UBIFS to ext4 ?
[General Questions and Answers] nathanski:
in my honest outlook i see ubifs as a hard to learn yet rewording,ly beneficial file-system as with ext4 you can disable its write caching and time stamp writing,, to aid in use with NAND applications,,, only thing is in my opinion UBIFS uses a nands half-life very well,,,,ware other file-systems may degenerate the life span of a memory chip a litle more acceleratedly,, further more i do believe those talks were on the grounds of using ext4 if we were unable to accomplish things that have seance became a reality,,,,,:D

[MENTION=2670928]TripFX[/MENTION] I can confirm too i flashed twrp others are sayin there is no touch, there is touch but its in the vertical fashion and buttons don't lineup vertically. Was able to swipe unlock holding device with camera up and swiping bottom. So the touch is displaced but does indeed respond to touch. The vol buttons do not function.

DONT USE GEORGES as his was made for v38 tabs and also doesn't fully work. We are now aware of the the exact problem and its a rather easy fix. v38 and v31 have different touch layouts being they have different lcd's.
