Default [Q] partition issue with mediatek n9002 note 3 clone

i just got a Star/Ulefone n9002 mediatek based clone of a Samsung Galaxy Note 3. the phone is pretty nice... i'm liking it. specs on it are pretty good, but i am having an issue with the internal SD card. when i ordered it, it was suppose to come with an 8gb internal SD card. i got it, took it out of the box and checked, and the system specs said that it had a 16GB internal card. originally, i thought, "Bonus!!" but the more i thought about it, the more i realized that this is probably bogus or an issue with whatever rom is flashed on it. checking needrom.com there are 2 rom images out there for it and they both list the original specs for an 8gb internal card. when i started loading things on it, i suddenly started to get strange errors about running out of space. it didn't make much sense. anyway, i rooted it with mtk droid tools, installed the custom CWM, and what not, and started poking under the hood. fdisk is giving me errors and parted refuses to even work on it. (maybe i am running the wrong commands, but attached are outputs).

anyway, i already know there is an issue with the ROM cause MTK Droid tools reports that it has an mt6582 cpu even though the software on the phone reports and mt6589. all of the roms say it should be an mt6582 also. not a big deal in my opinion.

my question is this... is there anyway to non-destructively fix the partition table? i have read alot about editing the EBR files to change partition sizes, but there has got to be a better way. also, i'd like to truely verify the size of the built in storage without opening up the phone and reading the numbers off of the internal SD card.

should i just get the latest ROM off of needrom.com and flash it? i don't know if this would fix the partition table either.

here are the outputs:

Default progress...

i take it by the deafening number of replys, no one has any idea whats up with my issue or any idea how to fix it. so i have been digging deeper myself and think i have come up with some solutions.

first of all, i was just planing on flashing one of the roms off of the NeedRom.com website, but i read a couple of posts on chinaphonearena.com and one in some german forum that listed a phone with my same baseband and ROM build, and when they flashed the new rom, it screwed up their touch screen. something about having an incompatible touch screen driver. i don't know if the person flashing the rom chose the correct rom, or incorrect rom, but it made me skidish to attempt this as a fix.

so i checked in on modifying the EBR files, which people have been doing on these mediatek phones for a while. i thought maybe one of mine was screwed up. i extracted the EBR1 and EBR2 file from my fine with MTKDroidTools and i pulled the files out of the rom update. i also took the scatter file generated by MTKDroidTools and the scatter file from the rom update. i compared them line for line. the EBR files are totally identical! as was the scatter file. address of where the partitions start and stop inside the phone are 100% the same. so flashing a new rom wouldn't have fixed the problem anyway.

i started googling around at the error that parted gives me: "Error: Can't have a partition outside the disk!" this is discussed elsewhere, but mostly on actual machines, not phones. there are some postings here on XDA, but none that address my specific issue. anyway, the ways it always suggests to fix it is to figure out which partition is oversized, used the sfdisk utility to dump the partiton table, fix it, and re-write the partition table to disk. simple enough, if you know what your partition table should look like.

back to fdisk, i reprint out a copy

this does indeed tell me that the internal flash memory is about 8gb (Disk /dev/block/mmcblk0: 7792 MB, 7792492544 bytes) but it is not obvious to me which partition is screwed up.

anyway, i'd love for someone that has an mtk6582 based phone with 8gb of internal storage to provide me with a dump of their partition table, then i could just restore it over mine, and it should fix the issue!... the command is simple...

Quote:
adb shell
su
sfdisk -d /dev/sdc > PT.txt
from what i see (i may be wrong here) but these phones run with something like 2 partition tables... there is the one that is physically connected to the first 512 bytes of the SD card. then they have the EBR's which map out all of the EMMC partitons. so there is just one big partition seen from the outside, but through software, we can map that big partition in to smaller ones by knowing start and end addresses inside that big partition. i tell you, it is confusing.

i'm sure if i use the spflash_tool and format my phone and re-install a rom, it would fix the problem, but i am nervous about doing that because so many people have had issues putting rom's on this phone. they report that even when going back to their original backup the touch screen issues persist.

anyone have any comments? any ideas? any mbr backup they could share with me?

I believe you read my thread in chinese forum, I have one here too, because my touch is not working well since the rom upgrade.

Anyway, I'm almost sure you have like me a STAR Ulefone N9002 MTK6582 (1.3GHz) with 8Gb total memory.
AnTuTu 17500 values are 6582, 13000 are 6589T.

The original ROM have 1Gb RAM, 2Gb Internal Memory, and 8Mpx camera.
The ROM you have, and the MARCH Rom Update of Needrom, make the fake values, and the ram and internal memory are not correct. The camera is updated to 13Mpx too.

If you want, here you could read the procedure to edit the MBR by yourself.

Or you could flash the JAN rom of needrom.

I'm not sure about what cause my touch to get screwed, I guess I will never know, but I will keep flashing my phones...
At the moment, I'm waiting for a new touch for replace.

Cheers and good luck.

PMoto.
