You must really be new to Linux eg android, how do you think backups are made? only via recovery? example MTK Droid Tools, you don't turn your phone off or go into recovery why in the world would you? makes no sense.

Linux eg android has no problem copying in use files, this isn't windows, it's similar to the way I backup my Linux I use tar, but done from running system.

Online Nandroid Backup hard to run an app outside of a running system.

Just help the [MENTION=5873934]george676[/MENTION] out, create a folder, open terminal cd to that folder

adb pull /system and upload it for the guy.
[General Questions and Answers] synius:
now which system do i pull according to MTD partition 16 + 19 are system.

according to dumchar_info MTD16 is labeled Android i assume this is the one im pulling

Partitions shows 18 partitions

19 thru 21 arnt shown i assume these are the main system, userdata, cache which are shown on /proc/mtd/

you said make folder ( on sd card ) in terminal cd to it and just adb pull /system

im just clarifying
[General Questions and Answers] vampirefo:
not on sdcard

cd to folder it's done on your pc, not sdcard.

open terminal cd to folder example

vampirefo@vampirefo-GA-MA78GM-US2H:~$ cd /home/vampirefo/Desktop/bob

vampirefo@vampirefo-GA-MA78GM-US2H:~/Desktop/bob$ adb pull /system

adb pull /system

System.zip Added to mediafire

previously asked if there is a upload of /system

it can be found https://www.mediafire.com/#af66xdpbd88vh at RCT6773W22 under the Original folder

file will be named system.zip the files are not compressed just stored i used 7-zip

if you dont see it there it hasnt finished uploading

at this point is the /system still useless until we can get adb thru recovering working then its as easy as adb push /system?
[General Questions and Answers] vampirefo:
Useless? LOL, no not at all.

When you first get an android, tablet, phone or what ever it is. The first thing you should do is adb pull /system.

Do this backup even before you root, Now you have complete stock backup.

You can use any file or files from this backup to repair your device.

After root do another adb pull /system.

Now do a tar backup which can be installed on the device when you need system completely restored.

All hope is not lost. I am not new to android. I have succesfully ported one of carliv touch recovery for our tab. its very old (doesnt work with touch only volume and power buttons) but its functional. it only has adb recovery mode, it doesnt work well with the /data partition even though it mounts it, however it can succesfully restore boot.img, recovery.img and system.img.

i will soon give and upload of it along with a cwm backup it created.

i used spflash tool to flash it to the device with one of the scatter files i found (will upload those two).

It can only be done on a windows 7 pc (any build or version) with VCOM drivers properly installed( i will post drivers also and how to install it, caause you will have to disable driver signiture varfication on your pc).

dont expect mush from this revovery it can only unbrick your bricked device.

it canot wipe data, so you will have to reflash stock recovery to do data wipe( even after reflashing /system, tab wont boot until a complete factory reset is done).

ohh...........the reason for such an OLD recovery is the fact thats its the only version of carliv which has ubifs support and cwm original backbutton because our tab doest support touch in recovery mode at the moment, at leas not on its present kernel.....

so look out ill start uploading all these thing in a while.

[MENTION=5873934]george676[/MENTION]

all you need is adb in recovery, and mount if you can get adb and mount to work the rest isn't important. The recovery I ported for RCA and now use on DL701Q, (which is almost the same tablet as this rca one), adb and mount works just fine, I thought codelover's port did also, I never checked it, perhaps it didn't.

Anyway doesn't matter as long as you were able to get the files you needed, to fix your tablet.

PS here are some ubifs recoveries that you can port if you want.

I use port_recovery-cwm-mod-kk_600-ubifs.img myself, I flash via fastboot.

So its possible now to have working cwm on the rca 7 voyager. I have not rooted or tried any hacking yet on my kids tablets but its nice to see things coming along. Also wish i could get a working cwm recovery working on my polaroid q10 tablet thats stuck in boot loop. I guess i can reflash stock rom from polaroid southern telecom sight. But if i had a stock filmware file is it possible to get working cwm recovery to work on it. Sorry to hi jack this thread but kids have rca 7 voyager and i have polaroid 10 q10 tablet.

when it finished,no come on.just black screan. windows can see it as mtk vcom port.

tryed flash preload cant ,bad scatter any help,please:confused::confused::confused:
[General Questions and Answers] vampirefo:
The scatter file was only for flashing recovery, my guess you bricked your tablet, the preloader file is no good. A good one can't be made, so no one can format or download preloader from flash tool.

One can only flash recovery, perhaps even boot and uboot but not system or preloader.

You are on your own.
[General Questions and Answers] vampirefo:
I just downloaded L_Speed from link you provided set it up to work on my tablet, first thing I did was change 666 and 999 to 10 and 11 those numbers are inappropriate around some of my family members.

Anyway I can't say I see any changes, perhaps it is working as expected, I never had any problems to begin with on this tablet, so willing to try a few hacks to try and improve tablet.

I have good backups, so if something went wrong returning to backup isn't a problem.
[General Questions and Answers] synius:
i did a readback and produced 1.6 gig rom_0 how do i dump split it into actual partitions

2nd question id prefer to make my own scatter file arnt the dumchar_info start addresses correct?

if not how do i go about producing one from device; directions would be awesome
[General Questions and Answers] QkTreasures:
So how did u restore back up, thru adb or cwm and is it even possible to get cwm or twrp recovery on these rca 7 voyager tablets. Thanks.
[General Questions and Answers] vampirefo:
Either way works just fine, these tablet's have ubifs partitions, if people remember that, they can use cwm to backup and restore, most people simply can't remember that.

---------- Post added at 07:31 PM ---------- Previous post was at 07:14 PM ----------

You don't this again is ubifs, you aren't going to split or unpack a ubifs image. When I flashed recovery on rca tablet the scatter file points for recovery were right.
[General Questions and Answers] synius:
For the sake of progress I question everything. Otherwise Everyone would just play follow the leader and only select few would ever achieve anything.

Now OK the start addresses may be correct. Because they come from signed updates But I wanna achieve the same results myself. It isn't a lot to ask for,like science results should be able to be duplicated instead of just taking info without questioning things

That's where ignorance is bliss but without ppl questioning crap there wouldn't be any progress so instead of being arrogant be a little more insightful

I believe nothing I hear, half of what I see, and everything I can do myself

I also read up on what ubifs reading it made what u said make more sense

Should a just said the scatter was signed from your updates where as I assumed that post about the start address were unsourced because obviously a signed scatter is proof enough
[General Questions and Answers] vampirefo:
Nothing wrong with asking questions, most scatter files can be made by hand or by mtktools.

The rca tablet isn't one of those tablets, it lacks the address info, so to get that info one needs help, eg rca signed zips.

Gotcha they did a good job trying to proof these tablets at least in that regards..

On a side note if any updates pass I'll unroot and update just to give a comparable update to triple on scatter info. More data the better

That would be the best way to do it, catch the update and upload it.

[General Questions and Answers] synius:
those are signed scatters, im sure there wont be any major changes to them unless theres a huge update, so regardless there as accurate as they can be for there propose; which is CWM,, backup and restore bricked devices

im thinking about preforming a flash of that CWM carliv touch recovery that supported ubifs and adb thru recovery.

i wanna get CWM recovery files uploaded just so once people get the CWM flashed on there bricked units its just a matter of downloading files booting recovery and restore from those files
[General Questions and Answers] TripFX:
Besides backing up a few partitions the test recovery i provide does flash and adb. codelover is just waiting for someone to report back that the scatter file he supplied for spft works once thats sorted out then we can get ext4 conversion and fully functional cwm/twrp.
[General Questions and Answers] vampirefo:
The first scatter worked for flashing recovery, I don't know about any other versions of the scatter file, glad you confirmed adb was working, never tested it, assumed it did, just never tried it.

I don't know if anyone with a bricked tablet ever got the flash tool to work, I doubt it, my guess a working tablet was needed to at least get drivers and such setup.

Doesn't work? Preloader is corrupt, you should be able to flash boot.img and recovery.img

[General Questions and Answers] TripFX:
just fyi when in preloader mode you shouldn't see charging screen.
[General Questions and Answers] nathanski:
well the flash had not the right perimeters even in many attempts

it should snap out of downloading mode upon reset and start correctly if i had the correct scatter perimeters and,or files.

That said I may have fouled out the sandisk nand back when i was playing with my first format and flash. but it is within hope that it should be resilient and take to a correct perimeter if i or we knew them. in MTK firmware files i have found many differences in the files and scatter files and have tried learning all that i can from them but feel lame in my paltry understanding of it all and well ubifs ... i found one company hosting a file that looked like one huge image but the scatter failed to load in the spflashtools i through it at,... and what of the MBR

i know there are people theat could re-flash this thing, but im left just to lust for; my as of yet unfounded knowledge. :cowboy: Learning is Hard um-kay... lol

I don't think, a bricked tablet will be fixed via splashtool, if the firmware I uploaded doesn't work, my guess nothing will. It's not possible to pull a usable working preloader from device.

[General Questions and Answers] vampirefo:
A scatter file is just a text file, it's complete, I think people think this text file is magic, it's not, just a text file. What is needed is the flashable firmware from rca, eg working preloader, and system.img.

It is agreed need the whole Firmware for this board, envizen em63 ts

What is interesting to me about the scatter, the info from device doesn't match its own update scatter. But I think its explained by the ubifs factor and how it operates on the device level , causing the mismatch
[General Questions and Answers] TripFX:
hence the reason for the test for bricked devices. once we get verification that someone has successfully flashed the provided recovery. Then at that moment happens we can then make the switch to ext4 instead of ubifs and make a full backup to hopefully fix most broken tabs if not all pending on the reason for the brick in the first place.
[General Questions and Answers] vampirefo:
Not going to happen, the preloader is no good. Once the device is bricked it's done. If the device can still boot into recovery, fastboot or bootloop it might be fixed, but if it's unable to do any of the above tablet is done.

I know that on some devices (particualrly samsung devices) people have made micro USB plugs that jump the correct pins that force the device to turn on in recovery or download mode (forget which one). This has been particularly helpful for users who have software bricked their devices.
[General Questions and Answers] vampirefo:
If one can get the device in recovery mode they should be able to get it into fastboot mode.

I had this tablet for two days, was able to port a recovery, setup dual boot, pull updates from tablet, and get tablet to boot into fastboot mode from off.

Hold volume up and power at same time.

Once in fastboot flash cwm recovery.

[General Questions and Answers] nathanski:
dual boot setup. how Would one do that, could you teach that?
[General Questions and Answers] vampirefo:
I can post guides, I made for other devices, but this tablet is UBIFS so you will need to make a dual cwm recovery.

Basically you need a micro sdcard, you make 3 partitions on it two ext4 one vfat.

I recommend a class 10, You need to take a stock boot.img open it change mount points from tablet to sdcard. you then back up your system, boot into the dual recovery, switch to ext4 recovery install the back up to sdcard.

Then boot into fastboot and flash the modified boot.img.

To switch back to using tablet instead of sdcard, boot into fastboot flash stock boot.img.

Can you explain why you've been saying it can't be done.
[General Questions and Answers] nathanski:
im not the one that said that or anything relating but i failed because mtk-tools is limited with its ability to run on our chipset and our ubifs format ,,, one can fake our chip-set or spoof it as the earlier one that has support but the ubifs side leaves it subtly corrupt,, devs do you all have corrections to my reply ,,, would love to converse this more....
[General Questions and Answers] TripFX:
until we get feedback as far as people being able to flash the recovery via flashtools we will begin conversion for ext4. so if you want to learn how to dual boot honestly your on your own and google searching or even searching in xda you will find what you need to pull it off but being we have ubifs i wouldnt count on it happening. Aslo be advised that in august i will be moving and when i do i will no longer have this tablet nor do anything more for it. This does not apply to [MENTION=4893922]codelover[/MENTION] as to he is free to do as he pleases and he may or may not say when he will be done helping as well.
