try flashing entire rom reflashing instead of just bootimg and dont forget to do factory wipe. report if it's back please use one of the following options when reporting

1. Works again - no touch

2. Don't know what happened but its working with touch

3. bootlooping can access recovery

4. bootlooping cant access recovery

[General Questions and Answers] codelover:
Your ROM dump does not seem to be correct, did you load the V3 scatter before dumping?

Once you loaded the scatter there should be some options for you to choose from, please use the following configs:

Anyway, i will need your stock recovery.img, can you upload it?

It would be great if you can provide more details when reporting, eg: explain which steps you used to flash, what error msg you see, etc, instead of just 'not working'.

Please try the new attached boot_V38K2.img, please replace the original boot.img in the ROM and flash all together.

Based on some of the files you guys provided i have to believe that there could be some different revisions of the tab.

Where synius & acejay3200 sharing the same tab, while TripFX has a different revision, or simply a newer/older ROM, can't tell for sure now until i have all the files.
[General Questions and Answers] synius:
tryed to do another readback this morning as requested my config looked exactly like that except when i put 0x81000000 in the start address it changed to 0x00000081000000 which it accepts

if i put 0x8100000000000000 i get address or lenght byte not align

even with v3 scatter loaded

hopfully someone can provide a direction to go from here..

codelover : http://www.mediafire.com/download/mulxjevmai45ejn/recovery.img stock image

also how did u dice the rom up

The first ROM I provided was according to the dumchar_info's start addresses 1.67 gigs (Figured this was incomplete)

I dunno how it looked diced and if it actually was complete

Was advised not too use this address

The second ROM was according to v3 scatter addresses 2.17 gigs

Noticed towards the end of read back speed and size stats skewed

In settings ->storage Flash info states firmware is 2.48 gigs

(Shouldn't this be the amount of data pulled from read back)

In /proc/mtd there are 2 system, cache, userdata.

Dunno if there's relavance

[General Questions and Answers] nathanski:
maybe its power level.

in reading other things relating to this the battery needed to be charged all the way up for some recovery options. on a un related sidenote for the factory mega download mode the battery needed to be out, seeing as its soldered in the last part of my comment is more of a non helpfull question ,,, but all in all when it was in recovery processes that shutoff.

I have this exact tablet. I got mine this Christmas so I haven't rooted it yet. Gonna root it 12/23/15... The day I got it...

I would try poot.apk and ministro but those you have to download superuser... Kingo android root I don't know if its safe again or if XDA has allowed it back on...

Z4root seems to work OK...

Haven't tried Linux root using CMD...

I ROOTED my LG LS670 using Poot and so far it seems to work...

I rooted my old ZTE Z993 AND Samsung Sch-r740c using Kingo Root... Both eventually lost os... Thanks to Odin I was able to put os back on Samsung but the zte is fully hard bricked now...
[General Questions and Answers] nathanski:
what you can do is use our new custom recovery and it has an option to root on exit

and by then you will have plenty of time to re-read this thread and find out what it is i speak of ..... hint its the rcatest.zip on the g-drive from tripFX...... and its the best way to keep safe as i recommend a 32gb micro sd card and doing a full backup that way your recovery is there from the start of your root adventure and if it turns south ,,,, boot the custom recovery and restore your working rom no hardship on snafu,z one year to learn this spflashtool install... thats doable

i need to find my lcd version should i temp flash cm recovery then go back to stock recovery
[General Questions and Answers] codelover:
Thanks for the recovery.img, i can now confirm the following:

You guys : [B]RCT6773W22-ANDROID4.4.2-1401-V31-V1.10.0[/B]
TripFx : [B]RCT6773W22-ANDROID4.4.2-3101-V38-V1.8.0[/B]

Yea, 0x00000081000000 is correct while 0x8100000000000000 is not, either way SPFT readback is NOT giving us proper dump.

By the way, can you check if the test cwm backed up your /system? if yes can you upload the system.img for us? (zip it).

If not, can you make another two dumps for me? I want to check if the addresses are correct on your tab.

1) 0x9000000 -> 0xa000000 (recovery.img)
2) 0x11000000 -> 0x40000000 (system.img)

If the dump still not right, then i might need adb access to your device, are you able to provide me teamviewer access? Thanks!

We don't need 2.48GB as that includes your /data too, which stores you apps configs & personally data.

There are many ways to dice the dump, you can find the guides on xda, but most of them are not suitable for this tab.

The way i did, i looked at the dump & backup files with hex editor for hours, guessed the about size and cut them manually, and hope for the best.

Can you double confirm if you flash the whole ROM again (with the old boot.img) you can still boot the ROM - without touch? (+ factory reset if needed)

And yes you can also flash the test cwm and get us the output for /proc/cmdline, not really important tho, just to check something.

There is nothing much we can do now until we get the rom dump that was used on your device.

EDIT:
[MENTION=6253458]synius[/MENTION],

1) Run the following as root and upload the file, the process will takes some time.

dd if=/mtd@android of=/storage/sdcard1/system.img

2) Optional, i need the above first, and yes, use the same V3 scatter and the addresses that i provided above.
[General Questions and Answers] synius:
1.)I have the ability to do a read back on both tabs as I have the other one waiting for repair of broken screen (cud try to emulate screen display onto puter) (friends tablet im getting fixed)

I have done "adb pull /system /storage/sdcard1/system.IMG"

exact command I used..

Will this produce what u need? Or do u want me to test cwm

2.) Two readbacks with those modifications to addresses

Am I changing the scatter? Or Am I using those as end addresses?

Confused as to what u need

Teamviewer is an option

All I gotta say is wow seriously

Manual hex split, thought of this method but lack of experience and vampirenfo said it was pointless so I stopped trying

Serious props for that ridiculous mess of binary

For info purposes picture of partition sizes, names, etc might be useful when you extract exact partition size

uploading file images ( link once upload is complete )

What I did is dd if=/mtd@everything of=/.... Then 7zip stored everything

I haven't started readbacks yet. Been doing life..busy

Do you still need those or is the purpose strictly to see if addresses r correct.

Was testing something with mtkdroidtools i cleared logs and started with fresh logs. I get a partial scatter in the logs

looks like the dumchar unfortuantly. Won't hurt flashing these addresses to see the result on acejay's device with my upload

Do not try this until advised too.

safe mode is an option ,,, tho its dumb how i make my tablet boot with safemode

i have had a few times "well maybe more than a few times" ware my system will not finish a fresh boot or reboot because whatever mishap i had done ,,, in those cases i will usually get safe-mode to boot by rapidly tapping all the hard keys right after the first boot screen loads into the second rca screen ,,, i have had it boot safe-mode once by just taping power button rapidly, just a idea dont know if it could help ...

added seen this option in other posts "To boot into safe mode just boot the phone while holding Vol Down. It will enter into safemode. Reboot the phone to comes out safemode."

I would not suggest using Kingo Root as I used it to root a Samsung sch-r740c (cricket CDMA galaxy discover) and it ended up losing the OS/ROM FOUR TIMES!!!

Thanks to Odin I was able to reinstall the stock update.zip and Bootloader etc and it worked...

Don't have any experience with this tablet but I am hoping it is a lot easier than most phones or tablets...

With this tab not being a really high-end device like Motorola or newer Samsungs I would hope that it be easily rooted using Z4root, poot and ministro II, etc.

and i told you the best way because if you brick the RCT6773w22 is its over, I do wish you had read my reply to your first post ,, root is nothing without a custom recovery and solid backup,,
[General Questions and Answers] vampirefo:
Does the recovery not allow custom backups? Advanced backups and restore?

You shouldn't give people your data, recovery should be able to do advanced backups, meaning you could select to only back up system.

If for some reason the recovery doesn't do advanced backups, you could a factory reset then back that up, it would contain no data.
[General Questions and Answers] nathanski:
wish i was willing to give up my current environment and do a reset for everyone

im not going to do that sorry. to much config time in my xposed framework apk,s and alike.

wish everyone the best; and i have more that i can link to as i have my g-drive set to give files to anyone with a link and im dumping the .9GB in full. i will share links to all files except data.
[General Questions and Answers] vampirefo:
Not sharing your data is for your security, example if a person installs your data on their tablet, they have access to everything you have on your tablet, passwords, bookmarks, apps, ebay account, paypal and so on.

Think of a full back as a clone of your tablet, system alone doesn't contain any of your info, just factory files, unless you rooted and added other files to system.

I am sure I have stock instable system for this tablet, just too lazy to look, lol. I backup every device I hook up to my computer, via script, been doing so since 2010, it's an almost automatic response.
[General Questions and Answers] nathanski:
yes i agree

i have no idea if a incomplete backup is restore-able thus i was offering my system.ubifs.tar "as is" for [MENTION=4893922]codelover[/MENTION] in hope of the making of a spflashtool firmware. but if a cwm restore is able to be done that would offer recovery from a soft brick state, a full spftool ROM would be good for the hard brick device. im losing hope that i restore my original RCT that i bricked with spflashtool way back when. most tablets are only going to be soft-bricked anyways

https://drive.google.com/open?id=0B90C5EpCsLk6WlVTVFdxYXAxanM&authuser=0

is it your own script or one available on the www. that is a great idea but restoring a backup was our problem, the stock recovery was locked and this clockworkmod made all the difference. providing a window-or-port into a bricked slate. and even cwm has to be flashed by scatter file and smart phone flash tool, but [MENTION=4893922]codelover[/MENTION] and [MENTION=2670928]TripFX[/MENTION] really have made all the difference with this device. Thank you guys !!!
[General Questions and Answers] vampirefo:
The current spftool rom didn't work for you? Yes most tablets should be able to be fixed via cwm recovery, either by restore or adb.

[MENTION=4893922]codelover[/MENTION] if you are interested you could port my DL701Q recovery over to this tablet, just unpack replace kernel and repack, if interested not trying to step on toes.

If you think it would help, with my recovery special instructions have to be followed, if followed recovery does backup and restore, via adb, normal, advanced.

Thanks a lot for the files & MTK Droid & Tool logs, this kind of clear things up.

TripFX's tab does not contain any partition address, hence why we used the OTA scatter's addresses previously.

If addresses are available in your device dumchar then you must use that instead, i believe you both have a different revision of the tab.

Oh hey, thank a lot for the link :good:, i will have a look at it later once we get this rom dump issue settle down.

Yes they are, and they could have different sensors for different revisions, eg: they found a cheaper chip to use that can help them save more money.
