[General Questions and Answers] TripFX:
Overclock: We may be in luck to overclock/underclock as well as overvolt/undervolt. I literally just found a section in our tabs that has the info today. ATM I DO NOT KNOW if 1. IF it will work at all. 2. If it does work if settings are lost upon rebooting or 3. it works even with reboot. Bare in mind we do NOT have source code for this tab. If we did then yes OC would happen. I will be testing later and ONLY if it works I will post an extremely detailed guide as everyone chip is different for the min/max it can handle due to the way manufacturing is done. I've been overclocking everything i can since i first got into computers back during the Pentium I days and know how to safely do it without causing permanent damage to the chip. Also those who where using the sgh-t679 back when i had that phone knows I posted a very nice guide for fine tuning the soc.

Debranding: 1st screen (white RCA dog logo) im sure could be. 2nd screen (the actual bootanimation) not sure where it is located. Normally its in either /system/media or /data/local i've checked both places and cannot find the placeholder for it.

EDIT: OC/UV is possible in fact I'm 99% sure i could do it with any mediatek soc now xD. As for an ETA on release for it. All I'm going to say is 1. AFTER I've set the config up for it and tested it for 72hrs (3days for those that dont know there math) 2. After we have a working custom recovery as those with the newer revision still can't mount /system with the test version of cwm.

i look forward to your testing. Thanks :)

Yes, TripFX was an awesome attribute to the sgh t679 back in the day! I used his guide & still do it to this day every time I flash the exhibit 2 4g, thanks Trip & [MENTION=4893922]codelover[/MENTION] for every thing! This is defiantly coming together nicely! OC/UV & CWM for this tab... I'd never expected it when I was unboxing this thing, NICE WORK GUYS!

[General Questions and Answers] TripFX:
my goal with the overclock is to either bring the tabs to either RCA's "advertised" which is 1.4ghz or the more preferred mediatek's "advertised" which is 1.5ghz. after looking at the settings i can say without a doubt that whoever wrote the config for it, was a complete noob. Let's see who else can spot the noobs mistake and why. :D

default freq = 1300000, volt = 1300
default freq = 1196000, volt = 1200
default freq = 1040000, volt = 1150
default freq = 747500, volt = 1150
default freq = 598000, volt = 1150
[General Questions and Answers] synius:
Id say the Volts look a little off for the lower frequencys which means at lower frequency's you don't save battery if underclocked

Weird how volts look similar to clock speed also

But I am a noob when it comes to overclocking androids

But you asked if anyone else could see it
[General Questions and Answers] TripFX:
for being a "noob" you are dead on it. the only diff between running at 1040000 and 598000 is temperature which would only change by 1-3c not much at all. So why they have the loweset 3 same voltage is beyond me.

heres what the new one looks like that i will be testing later this isnt the final config either

default freq = 1400000, volt = 1300
default freq = 1300000, volt = 1275
default freq = 1196000, volt = 1200
default freq = 1040000, volt = 1150
default freq = 747500, volt = 1125
default freq = 598000, volt = 1100
[General Questions and Answers] synius:
Looks like a decent spread overall

the higher default will use more battery overall but shouldnt lag
[General Questions and Answers] TripFX:
Actually your wrong this about what you said for what looked wrong and WHY. Yes there is a better spread and higher performance however there won't be any difference in battery drain at max usage then stock however when your CPU scales down you will save more battery then stock.

EDIT:

synius, acejay or someone else with revision v31 please

adb shell mtdinfo -a > upload_to_xda.txt

for us thanks.

mtdinfo
[General Questions and Answers] TripFX:
you forgot to add the -a to that command. please redo the command properly.
[General Questions and Answers] synius:
this is the file aquired frrom that command

it made the file within the root of the device i used es file explorer wit root to move it to sdcard where i pulled it off and uploaded it

if u need anything else please dont hesitate to ask

the first mtdinfo was the one push to the computer ( nice and orderly)

the second mtdinfo is the one that was from sdcard ( the way things are not word wrapped )
[General Questions and Answers] mattkilla420:
Looks like a lot of interested people in testing and getting this working. A Lot of the talk was beyond my knowledge but have you guys successfully rooted ? I see you haven't gotten the rom yet just wondering in layman terms where you guys are with this?
[General Questions and Answers] TripFX:
root yes. kingo root, iroot, few others work for rooting this tab. recovery and so forth closest we've ever been eta still unknown as when we know you will know xD

Off subject from tab but still android related. FYI you can now start pre-ordering Razer's Forge TV on amazon now. I for one will be getting one as it's more open on hardware level then nvidia's proprietary version some time this summer.

[General Questions and Answers] acejay3200:
is there any way to remove superuser .apk without booting into android or recovery because thats when mine is freezing
[General Questions and Answers] synius:
was it already present on device or did it appear after rooting?

chances are it may have been made a system app

this can be dangerous as another person had created a bootloop from intregrating titanium back up to system

this action alone can cause bootloop

the rooting method i used is:

Download aptoide from browser, search for kingroot and install it open it and let it load push the green button at the top of the app with the word root in it

itll takie a couple minutes and it will install kinguser and su

it you wish to change this app to superuser or supersu

i changed to supersu pro and disabled superuser from prefrences and reenabled it, closed the app.

reopened the app and followed the su prompt for su binary update clicked normal waited and then rebooted

and then checked root by opening es file explorer and enabling root explorer when i was prompted for premissions it had switched supersu applications ive had no problems

i would not intregate anything into the system as it can cause bootloops, not 100% but it can happen
[General Questions and Answers] acejay3200:
it was in the rom that i flashed from here
[General Questions and Answers] synius:
This message is for codelover and tripfx. Should I uninstall busybox and unroot. Provide a new system IMG for acejay to flash. This way he can reroot and install busybox

Acejay does it let you do anything before it freezes example install a apk or run anything or does to boot froze. Example if I was to provide aptoide or kingroot would it work to at lest try to fix superuser. once you get superuser working properly we can erase the old superuser.apk from system

Could also try supersu try to update su binary normally of that doesn't work goto preferences in supersu disable superuser and reenable superuser then close app entirely. Start supersu again and try to update su binary normally.
[General Questions and Answers] acejay3200:
goes to homescreen after setup when a program asks for root access the system freezes i try to unroot it reboots gets stuck on second rca logo
[General Questions and Answers] TripFX:
have you tried updating supersu first via playstore? if not try it it should ask you to update binary which should work as newer builds did for me. Otherwise please wait patiently plz and ty.
[General Questions and Answers] synius:
do you get a chance to grant premissions or denie premissions

http://www.mediafire.com/download/h7udx68cnpfhvd0/KingRoot_3.5.0_25.zip

unzip, place in sdcard in settings allow install from unknown sources,

Or as trip said supersu update binary

install try to reroot

in the end you might need a clean stock flash and root and busybox yourself

have to wait and see what tripfx N codelover have to say

Updated:

I had gotten nandroid backup pro for free and backed up

Is there any usefulness if I do not have a custom recovery (wud need custom recovery to restore)

It did generate files

Cache.ubifs.tar data.ubifs.tar system.ubifs.tar md5.chksum recovery.log

These are my current tablet I imagen data contains all my user data

Therefore if these do have any potential I'll factory wipe install nandroid pro and provide a stock rooted with no accounts associated might be a chance to perform restore from recovery

My RCT6773W22 only boots up to a "No command" screen. The screen flashes/flickers about every 15 seconds. The volume buttons do nothing. I have read through the thread and can not find a solution that works for me. Any ideas?

Also it has never been rooted/been attempted to be rooted. Thanks in advance!
[General Questions and Answers] synius:
Please identifie the rct6773w22-android4.4.2-(finish this line). When it boots recovery you'll see it, Depending on version

Will depend if flashing will help
[General Questions and Answers] synius:
acejay have you gotten the CWM test working when you flashed just the recovery

( i have files from the forum for twrp, carliv touch recovery with ubifs support ( also supports vol + and - along with power as confirm buttons) and the cwm test

(example you flashed the entire rom) thats perfect

(unclick everything except for the recovery)

try to flash just the recovery

what i wanna try to do since we have the same revision tablet is pull off

the nandroid backup either with cwm support or twrp either one you wanna try

i will then provide you a completely stock recovery with the exception root via supersu + pro key and busybox will be the only things included in the recovery

ill skip setup and not assiocate the stock tab with any private information ( emails, etc )

with any chance if you have gotten the recovery to boot its worth trying to restore from the completely same working tab

you place the recovery files on ext sdcard, boot into recovery then select back up/restore then find the backup folder and let it do its things, before you reboot tab clear dalvik cache.

im basically providing you with essentially a clone of my device :P

if your willing to try this let me know and ill start saving the apks i need to perform the backup without any assoiations to any accounts

in theory this should produce decent results
[General Questions and Answers] acejay3200:
cwm works for me i would like to try it

---------- Post added at 01:42 PM ---------- Previous post was at 01:15 PM ----------

i have better luck flashing through recovery there is less chance of a transmission error
[General Questions and Answers] Jory76:
Not sure if your reply is for me or acejay.

If its for me, well thats the issue, I can't get into the recovery. I get the "no command" screen and thats it.
[General Questions and Answers] synius:
the comment was for you to identifie your tablet version as flashing different revisions on tablets is hardware problematic to know for sure to tell you what to do i need to know that

So doesn't boot up normally, and doesn't boot to recovery

Unknown version of tablet.

could be possible to do a readback using spft but im in no way able to determine the revision myself as that developement was achieved by codelover and he by far exceeds my exprience getting readable data

im passing this to someone else please

post results after boot hopfully we fixed the superuser freeze

This is a nandroid backup pro backup
[General Questions and Answers] synius:
[MENTION=6315294]nathanski[/MENTION]

also checkout the nandroid backup if you are having superuser freezing issues

Will require cwm to restore but supersu pro and nandroid pro are already present
[General Questions and Answers] codelover:
We will need to first determine your tablet revision before we can proceed, do you remember what is your tab version?

The version can be found at Settings -> About, something like V31 or V38? (eg: RCT6773W22-ANDROID4.4.2-3101-V38-V1.8.0)

If not, you will have to do a read back and send the files for me to check, you can zip the files and upload them here on xda.

Assumed that you have drivers installed and SP Flash Tools working, load the attached scatter and do the following readbacks.

Read back #1) Start Address: 0xa800000, Length: 0x800000, rename to ROM_v31, leave other settings default

Read back #2) Start Address: 0x9000000, Length: 0x800000, rename to ROM_v38, leave other settings default

His tab has other problems not only supersuper issue so cwm won't be able to help him atm.

But yes i was hoping you can make another clean readback, but i am not sure if the superuser that you used have 'Full Unroot' feature like SuperSU.

The unroot must be done properly to ensure no dependency files left or else the output will be the same like current one.

Well, we have got TWRP 2.8.6 patched and so far everything looks good but we are undergoing extensive testing to ensure everything is working correctly before we release it.

.
[General Questions and Answers] synius:
H

I have a couple things.

In regards to acejay the backup I provided should fix and replace the superuser.apk for supersu pro. That is if it restores correctly.

1.) I could make a twrp compatible nandroid backup for you

With updated SuperSu binary and busybox already. So its as easy as restoring. From twrp recovery

2.i would have to clean root,busybox, factory reset then right after setup skipped, non associated to any email read back to usrdata

Wouldn't be able to use dd if= of= without root and busybox right?

To pull images like before.

had to reformat used v31 rom booted first time used kingo root to remove root tablet works normal starts up all the way into homescreen only thing now how to correct storage space

---------- Post added at 10:58 PM ---------- Previous post was at 10:55 PM ----------

under settings storage says total space is 4.00gb firmware says 3.06gb only 0.94gb avalible to apps is there a way to correct this

---------- Post added at 11:17 PM ---------- Previous post was at 10:58 PM ----------

factory restore don't work either just checked that
[General Questions and Answers] synius:
weird how the total space is messed up

format all + download ( this has to be done to clear any remaining files on the nan)

sorta appears to me as it may be installed on top of the remaining os ( not 100% )

v4 scatter + files

the rom itself isnt that big

can you explain in details the process you took what you did

everything no matter how manute

disregard this if you did that just brainstorming

[General Questions and Answers] acejay3200:
there is 3 gb not partioned not in use by anything
[General Questions and Answers] synius:
i think i know what your problem is

its the usrdata we left out

figuratively speaking its a partition of empty space

( for someone that can help )

is it possible to determine the end address of the userdata when i do a stock unrooted readback to add that 3 gbs

in theory its the only thing we didnt include in the rom because of personal information and such we kinda thought the excess space would partition itself to userdata (because it is blank space but its also a partition which could explain your problem
[General Questions and Answers] acejay3200:
is there something i can do to get that space back tablet will not use that space as is
[General Questions and Answers] synius:
its in the hands of someone who can give me the end address for userdata for the readback

bmtpool says 0x0 which doesnt help me right now

(unless bmtpool address 0x0 refers to the rest but conflicts with start address would I use the old scatter bmtpool of 0xffff to read back the entire internal flash)

The address 0x000000FFFF on the bmtpool gives me a readback of 3.99 gbs might be the issue the bmtpool having 0x000000FFFF as the start address instead of 0x0

Unless while rooted and busybox I pull usrdata.img and you flash that under usrdata

Did you try that nandroid backup? Just curious it has a stock usrdata

Does anyone agree with me this cud be the issue

Literally sounds like usrdata wasn't allocated at flash

also my v31-1.10.0 tablet is unrooted and busybox is uninstalled, ready for stock readback, i need an address to include usrdata

i also created a twrp recovery backup with supersu pro and nandroid pro ill upload everything once i have collected everything

Twrp nandroid backup (w/ busybox + supersu pro + nandroid pro included)

Cwm nandroid backup (w/ busybox + supersu pro + nandroid pro included)

==**== i made an edit compairing scatters I changed v4 userdata partition size according to v1 scatter userdata size at first then checked device and changed it to 0x17f000000. changed cache's type to ubi_img also. (loaded the updated scatter into spft and doing a readback to bmtpool) 0x0000000ffff0000

ill also provide the Rom + v4.1 scatter as a raw source for codelover.. incase anything else is needed

*it was missing partition size and used 0x0 I change it to 0x17f000000 which it stated in the device as size (this might fix acejays userdata problem ) and allocate more space to userdata

as is correct for the v31-1.10.0 for userdata size

Not v38

tripFX did you ever find the jar that linked to the cpu scaling: mtK is crazy with there file-system mounting, i found the same file you spoke of modifying, I thought of modding it but never heard back after your initial three day test posting.... THanks EveRY ONE wish "all' the best...
[General Questions and Answers] vampirefo:
It's in proc, your mtdinfo isn't correct, you need to do it as you did before with the -a option.

Your mount shows you aren't mounting cache which is a problem, cache is needed for stability of tablet.

that is only one of many files that need to be modified. Just wait a little longer as we are almost ready to release twrp for both v31 and v38. As the files that needs to be changed can only be done via flashing with custom recovery.

there are only 2 differences between scatters userdata partition size and cache's partition type to ubi_img

i agree with vampire looks the same.

the scatter should fix these issues

unless i suspect the address of bmtpool is wrong, on my device it shows it at address 0x0 like preloader

[General Questions and Answers] vampirefo:
Both scatter files cache is wrong, neither scatter file creates a cache partition, so that explains why cache isn't mounted.

Doesn't explain why fat partition was created though.
