Awesome! How are you liking the Liquid? Is it good enough for daily use (browsing, using some basic apps, a little 3D gaming maybe)? Thanks!

I really Love the screen. 4.3 inch is just perfect (920x540 resolution). . And 1 GB Ram is enough for multitasking, for me atleast. Here a some screenshots of benchmarks i just made. With a lot of apps running in background. (550 MB Ram free) . This phone is really amazing (compared to a galaxy s plus) . The only thing you may not like, that it has no front-facing camera. But you may like the fact that it boots within 7 seconds .
I hope I answered your questions, and feel free to ask something you want to know.
Btw, I'm from Holland, and I bought this phone unlocked for €180,-

Are you seriously saying the (dual-core) Galaxy Nexus S is SLOWER than the (much cheaper single-core) E350? Damn makes me want the phone even more!
And yeah I noticed, I'm from Belgium and thinking of buying this phone (also carrier unlocked) for €199.

Never mind, I was thinking about the Samsung Galaxy Nexus, which is still a bit faster, but not a lot it seems.

Yeah indeed, I got the two mixed up. Still impressive.

I will have this phone next week :good:
Thanks for the root e for the governor change, i will try when i have the phone...
WE NEED'S DEVELOPERS ON XDA
I follow the MODACO forum...

i am thinking about getting a Gallant Duo so thanks for the info and the files, jaapstreepjan!
can you tell me how long the battery will last once you have set a proper governor (either conservative or on demand)
would be great, thanks!

I can reach 24hours, with intensive usage.
(but i do have the single sim version. So I can't tell you anything about the duo sim version)
I'm charging it every night when I'm asleep

@jaapstreepjan
1)
You recommend ROM Toolbox. I am interested with its capability of doing nandroid backup. But as far as I know, there is no custom recovery yet for the phone, so even with ROM Toolbox, there is no way to have nandroid backuping the whole system+user+recovery data. Could you confirm ?
The default Android recovery backups only user data, so it is not a really fail-safe for a rooted phone (for example, system application deleted by error).
2) During a phone call, by pressing menu button, there is possibility to record the call. Once recorded, I do not known where the recorded file is stored. My search inside /mnt/sdcard does not show anything. Do you know where this file is located?
Thank you.

1. The Rom manager in Rom toolbox doesn't work. I confirm that. I was working on a CWM recovery, but i don't have enough time and knowledge. So when I get time, I'm going to try to compile one.
2. I didn't even know there was a recording option while calling. will research that and inform you when i know more.
Thanks for the tip ^_^

Hi! Thanks for the tutorial, it will most certainly will be very helpful to get all advantages from my android device..
However, I am facing a terrible problem that I don't know how to solve.. I cannot connect my acer to any computer! When I connect the usb cable, there's no messages popping up, it just charges the smartphone..
I have tried with 2 different cables and in 2 different computers, so any suggestions about how I should proceed? The mobile phone has less than a month and never fell down, so I think it's very unlikely that it is broken.. moreover, the first time I turned it on, when arrived, I was able to connect it to the computer as a "hard drive"..
Please help me rooting my phone, guys!

Go to device manager on your computer, uninstall all acer e350 related drivers. reboot your computer, connect your phone again, and then reinstall the drivers. that should work. Good luck! :good:

Excellent news: the record file is created at /mnt/sdcard2/PhoneRecord directory.
The file name is of type YYYY-MM-DD_hh.mm.ss-xxxxx.3gpp.

Nice to see it's rooted. I was actually thinking on buying this phone, but one thing holds me back: do you think there will ever be a CM or MIUI rom for this device? I doubt because I imagine the custom dual-sim managment part of the phone software would be difficult to port... but maybe I'm wrong.

Hello,
Currently there is no custom recovery to perform nandroid backup. The default recovery backups/restores only
user data so it is not complete. In the meanwhile maybe 'dd' command could be used for manual backup the different
partitions. 'dd' could be invoked from a zip (script) inside the default recover.
But we need the mapping of different partitions.
From the Liquid Gallant 'ls -l command':
[email protected] -> /dev/block/mmcblk0p6
[email protected] -> /dev/block/mmcblk0p2
[email protected] -> /dev/block/mmcblk0p1
[email protected] -> /dev/block/mmcblk0p4
[email protected]_ro -> /dev/block/mmcblk0p5
[email protected] -> /dev/block/mmcblk0p3
Usually a custom recovery backups recovery, boot, system, data, cache (and /sdcard/.android_secure).
Question: How are they mapped with the Gallant partitions?
recovery <-> ?
boot <-> ?
system <-> android?
data <-> usrdata?
cache <-> cache?
And what is :
fat ? need to be backuped?
sec_ro ? need to be backuped?
Thank you for any idea or answer.

Thanks for posting this! Worked great! So far i haven't been able to find a tool to undervolt the CPU did u manage to find one? Seems like all those CPU control apps dont play nice with the mt6575 CPU...

If i have enough time, i will defenitely make a cwm and CM, but i have absolutely no experience, so i will have to learn it first.
the dual sim management part shouldn't be too hard to port. But now i'm going to install ubuntu etc, and trying to figure out how to compile CWMR

from what i know so far:
ebr1 = recovery
fat = sdcard (internal i think)
and sec_ro = android_secure or boot...
not sure.
will investigate further

for undervolting you need a custom kernel.
and undervolting requires a lot of testing,
so you must have patience

[Stock ROM] CAT B15Q ROM development

CAT has not yet managed to put official stock images or the kernel source code available - even for their oldest phones (even though they are required to)... so here's at least a beginning.
Every firmware archive contains the four partitions UBOOT, BOOTIMG, RECOVERY and ANDROID (/system). These are flashable using spFlashTool, a howto is here: http://forum.xda-developers.com/android/help/howto-firmware-flashing-cat-b15q-t2989627.
Please note that these firmware files were dumped from an EMEA B15Q, dual-sim - there are reports of other models being available under the B15Q model name. In doubt, always make a full backup using spFlashTool's readback mode before flashing one of these. (You should be doing these anyway before every firmware upgrade, CAT doesn't test stuff like compatibility with root!)
Credits for the scatter file go to bigal1337. Credits for spFlashTool and the driver package go to Russian website mtk2000.ucoz.ru.
1.019: https://mega.co.nz/#!UEp0hS7b!6aiqETvAu1Q9voNZtMLWoztbF7FGX0j9Pnj4rBhwoD4
1.022: https://mega.co.nz/#!YEAwmbxI!rVonLybVo6PL2bhNloGStR0EacKwE3-3hILzY9ri0NY
Scatter file: https://mega.co.nz/#!UEp0hS7b!6aiqETvAu1Q9voNZtMLWoztbF7FGX0j9Pnj4rBhwoD4
Tested tools:
MTK Driver package: http://mtk2000.ucoz.ru/down12/MTKUsbAll_0.9.2.rar
spFlashTool: http://mtk2000.ucoz.ru/down12/SP_Flash_Tool_exe_windows_v5.1420.00.rar
Do note that the drivers appear to be modified Google drivers and thus have no digital signature; you will need a 32-bit system to use them.
Flash mode needed for spFlashTool is achieved by removing the battery, starting the flash/readback in spFlashTool and then plugging in the USB cable. You may put in the battery afterwards.
The recovery, fastboot and factory test methods are entered by shutting down the phone and then:
recovery mode: press power + volup for 2 seconds, then release power, release volup as soon as recovery has booted
fastboot mode: press power + center for 2 seconds, then release power, release volup as soon as recovery has booted
test mode: press power + voldn for 2 seconds, then release power, release volup as soon as recovery has booted
In case that a B15Q or general CAT board is opened (for the B15, B15Q and the flagship S50), I request that this thread is moved into its rightful place. And in case anyone wants to help me with a CyanogenMod port, please PM me.

CWM Recovery
Using mtkdroidtools, I have built a CWM Recovery image to be flashed with spflashtool, all based on 1.022 firmware. There are two variants:
using stock Mediatek USB IDs: https://mega.co.nz/#!FRxxiRSC!EN5gORcYPtFONlH3V8-Yco3_w9RGhE8jevicedlT2kI
using Samsung USB IDs: https://mega.co.nz/#!8MowBZCJ!fhs-mXpGZR36g9JJh3IONIlOKBHIktFBDIrpynlK84M
The difference between them is that recovery #1 uses the same Mediatek USB id's as the stock image (and thus requires the Mediatek drivers in Windows, which sucks because these are not signed), and recovery #2 uses the USB IDs from a Samsung tablet - so you need the Samsung ADB driver instead, which is digitally signed and far more stable than the Mediatek.

Samsung USB ID fix
See above for the reason; the boot.img with Samsung USB IDs is at:
1.022: https://mega.co.nz/#!gcREQJKD!FCrxl9-PWSWM0_2Nh9D1KeA-zFV4nS9dmd6zjVnqPLc

Hybrid SD Card
And the CWM Recovery + boot.img for those who want to try out the "hybrid SD card" from http://forum.xda-developers.com/android/help/howto-external-sd-card-internal-storage-t2989650, the two images of 1.022 are here:
boot.img: https://mega.co.nz/#!MMYx1BYY!Rlnrxl1MURMgnx2luvPdYKJjMmNMbYVIGyFlGeRVcMY

I used this, it's great! Now I have 16gb of "internal phone memory" and 14 of "external" sd card. Did not see any performance issues with my SanDisk Extreme III. Do not need root anymore, I wanted it only for link2sd. Thanks harddisk_wp!!!

Great to hear someone was crazy enough to replicate my hack But I strongly advise you to keep off OTA updates with the hack enabled.

With or without the SD hack? Try putting the SD card into a Windows machine, chkdsk the fat32 partition. Then plug it into a linux machine and run e2fsck on the data partition.

I tried the sd hack. There was a problem with my sd card partitions... but i reformated it with partition magic and now it works like a charm. No lag or anything.
Better than i was thinking
Greatings!

after one week
OKAY,
after one week of usage my phone became laggy and unstable.
Maybe this is because of my sd card but.... its 10class, i dont know
So i reflashed with the original partitions and now its fast and stable

Custom Rom
Will there be any possibility to create a Lollipop rom for this device?

proximity sensor problem
Do someone have the problem with the proximity seonsor that i have? There is a screen turning on immediately after turning of when the phone is placed next to my head when i am calling. This leads to a lot of changes in settings and everything that my face is changed durring the phone call.
I tried a lot of apps from play store that "fix" the problem but... they work not on 100% proper.
The sensor is working at 100% i have checked it already.
Please give me suggestions because its very annoing!!

I had the same problem. CAT support told me to reset the phone to factory. I tried a lot of other things but only the factory reset helped me. My sensor was also working correctly, I also tried several Apps to chack this.
Give it a try. I know it's a lot of work, but it was (in my case) worth it. I changed the time an date settings with my face which lead to missed alarms and oversleeping

I will give it a try
I need the phone rooted and i am not sure if the cwm recovery can be flashed over 1.19 as it was my original rom and i flashed it to 1.22 from files here on the forum

any news about any cyanogenmod rom?

Just to tell you that the new official update is awsome!!! Upgrade as fast as possible Greatings!

CAT B15 help
Hi guys, i'm sorry i have to ask this in this forum but i've been asking for a couple of months now, and got no answer. I have a CAT B15 (not the B15Q). It is single sim version (IMEI write on the back) and i managed to do plenty of things in it. I swapped memory and worked fine, and even i installed a Dual Sim android rom and i managed to use the secondary Sim bay in it (that was tapped with a plastic fake sim) and used the phone with 2 sims for like 2 weeks. Then i started to play with deodex and build.prop and softbricked the phone, but it was piece of cake since it is easy to unbrick. The problem was that i wrongly flashed the phone with scatter file, and flashed all partitions in it, EBR1, MBR, UBOOT, etc, etc. The result was a non-working dual SIM phone. Everything works, but the SIMS, it does not detect any SIMs in it, in any of the SIM bays, and the IMEIs are wrong numbered. I did no buckup of the phone so i'm pretty screwed. I've been asking for someone to upload the EMEA_SS or US_SS ROM for the CAT B15, but nobody responded. I thaught maybe the CAT B15Q has a similar software/bands flashing partitions, but that i leave to you for answer. Anyway, if any of you has the possibility of taking the images of a single sim CAT B15 it would save me this awesome phone for me. I'm also willing to give a 20GB account of ownCloud server for 1-year free of charge if storage space is needed, no problem. This are the links i've been searching and asking.

VKWorld VK700 Pro , Root, Philz CWM recovery , Partition extended to 3gb

Hello
I bought this china phone called vkworld vk700pro . rooted it and used the official firmware to build recovery cwm and modified the EBR1, EBR2 files to extend the app partition size from 1 gb to 3gb .
Make sure the mtk drivers installed before u do this .
1- Download the Official firmware from here.
https://drive.google.com/file/d/0B_lwKUeCfjkPSXlHV0FFUF9VWTA/view
unrar it ,
2- download below link , its all what u need to root it and flash the cwm, ebr files .
https://drive.google.com/file/d/0B1YQfWNB26xbTTdLQWNwZzM0aU0/view?usp=sharing
unrar it .
3-backup the ebr1,ebr2,recovery.img,checksum.ini files from the original firmware in case something goes wrong.
4-copy ebr1,ebr2,recovery.img u downloaded from the second link and paste them in the official rom folder .
5-rename the ini file checksum.ini to something els like cheksum_old.ini .. this file is in the rom folder .
6-open SP_flash tool and locat your scatter file which is in the rom folder and hit download .
7-when its finished root ur device using kingo root software .
this a a quick demo i made on YouTube to how to do it .
https://youtu.be/XfI2tXf-CqY

Thanks!
Thanks so much for doing and sharing this! This is just what I needed for my daughter's phone since she was having trouble installing apps with the 1GB limit.
Have you tried to install another ROM on this device? If you know how, please share and make another video. The youtube video was very helpful in getting the 3GB partition to work on my daughter's phone.
Awesome job! :good:

Glad it helped u , i did not try another rom , i think the stock rom is pretty fine . no blotware apps or junk adware .. the only think i hate about this phone is the signal its very week it won't go to one bar when 3g is enabled . i was going to hack the gsm antenna but am not much into hardware soldering ..

I've removed one link from your OP. The host site you used for that one is not allowed on XDA, as it requires registration to it, or social media sites, to use.
Please replace it with a direct download host site link.

Do you have make video tutorial?

Any one try that? Can it really be expanded from 1GB RAM to 3GB Larger RAM? If true, it sounds wonderful!

it should work , it working for me i got 3gb partition ..

I can confirm that this works. Only problem I had was installing the MTK drivers before starting, because I'm running Windows 10 and I think the OP is running Windows 7. Just search online, download and install the drivers first and then follow the excellent video created by OP.

hi there
great tutorial do you have any problems with the gps on this phone i have one and i cant get the gps to work.
any help would be much appreciated.

Maybe i'll try it by myself one day. But still a little worried. Thank you all the same.

Can you post a tutorial using Windows 10?
I tried installing Win10 drivers with no avail.

I have the vk700 not the vk700 pro cannot find any hardware differences so my question is if anyone knows if the procedure will work with vk700 too.
Thanks in advance

Worked very well, just lets get clear some steps:
1. Download
2. Unzip
3. Run the tool, find the file.
4. Plug the phone, turn off the phone.
5. If u get an error after the installation, just try again with the battery phone off. Is not breaked yet.
Thanks OP.
P.S. Im using it with the MIUI launcher (look for it in the miui oficial forums), and goes very smooth.

I can confirm that this works. Only problem I had was installing the MTK drivers before starting, because I'm running Windows 10 and I think the OP is running Windows 7. Just search online, download and install the drivers first and then follow the excellent video created by OP.

How can we do to make the 1GB ROM of this phone to be 3GB? I don't quite follow you. And if you want to get an affordable smartphone with larger RAM, we can get the Bluboo Maya with 2GB RAM and 16GB ROM.

Well there is a tutorial at
cinafoniaci.com/smartphones/guide-e-tutorial/vkworld-vk700-pro-aumentare-la-partizione-per-le-app-fino-a-3gb
Me neither dont speak italian and yet easy to follow. I mean...if ever crossed path with flash tools - hard to forget since it turns to same
me,however, have the problem after flashing related to camera. no switch icon anywhere neither any app recognizes there is a front one,just rear.
tried cleaning data,cache, general system reset and nothing helped. is there a way to manualy ad another cam with different id and force android to accept it?

This is only for chip mtk 6580?

Is anybody out there who has rooted VKworld VK700X? I just can't find any instructions on that topic, I just found lots of misleading titles on the net. I'd like to install GNU/Linux on this outdated phone I don't use anymore.

Trojan
Had any one else had a warning about a Trojan hidden in device management 1.0
Have re flashed more than once trying to deal with chrome err_connection_refused problem, every time the Trojan is back, you have to use titanium to get rid of it.

Tablet is brick!
I have a P98 3G A9H8. I used the flash tool here to install the ROM using the "download" option & I got an error that the ROM is not there. I tried to start my tablet immediately & I could not.
Then I chose the "firmware update" option and it came back with a list of errors (3 errors). I tried to power up the tablet again- again fail- nothing happens at all. Not even attempt at rcovery.
In other words, by flashing this rom, my tablet is not BRICK.
Does anyone know of a way to unbrick it? I am thinking perhaps flashing a stock rom can resuscitate it? I googled but could not find its stock rom to download.
Any help will be appreciated.

This ROM is just crewed up!! So many different errors it is not funny. Don't ever touch this- it screwed up my tablet big time.

md1_db and ap_db files gretel A7
md1_db and ap_db files. Are there ways to get them somehow. I lost my IMEI and trying to write it with SN writer, but manufacturer did not send me those files, just tool.

Menaged to restore IMEI. Engineering mode doesn't work because there is no CDS settimg. SN writer also not working because of mentioned files missing.
At the end I had to root device, install mobile uncle apk and another tool within mobile uncla app and write it from there.

Hi, I have a gretel a7 cell phone that keeps restarting and showing the message "interf sist stopped" I would like to know if the rom made available in this topic is multi-languages, since I am Brazilian, and if following your tutorial I can use the cell again.
I appreciate the attention

Yes it is multi-language, you can follow the tutorial without any issue.

Just pay attention to keep an EMEI. Don't select download only, ot format+download. Keep it on firmware upgrade!

Hi,
My father have the same phone, and the same issues. I plan to flash the stock ROM and root it.
Which apps have you removed (pretty important, cause I can access to the phone just for some days, when I visit him) ?
And how ? Something like root uninstaller can do the trick ?
Thanks a lot

First you have to flash ROM.
NOTICE:
1.before connecting phone to PS always remove battery
2.Doing "Firmware upgrade" will not work, "Download only" also not working. Do "Format all". This will erase your IMEI, but after flashing and rooting you can install Chamelephon from Play Store and write your IMEI.
I did it with:

There are rooting instructions for rooting with TWRP through Recovery mode, in Power point on this Forum but can't find it right now. After rooting install Unninstall app from Play Store and it would suggest what apps you could unninstall. As i remember there are apps like Medias and com.android.com.service, and so. You should even delete it in file manager if located.
AND VERY IMPORTANT, if you ever try to sign in vit another Google account, or new account to your device, medias will emerge again, so you need to erase it again. It seems that it is a bug that appears with signing in to Google.

Thanks a lot for your time
What exactly do you mean by :
before connecting to PS (<= is for SP Flash Tool ?) always remove the battery (it's seem also unclear in the ppt, at a certain point, it's said to turn off the phone, then connect it for doing things with SP Flash Tool, then turn on by pressing Volume Up and Power Buttons. Is it right than we have to do it with the phone off ? And without battery like you suggest or we just remove the battery for a complet reset, and put it back when connecting to SP flash Tool, or let it remove when using SP ?)
com.android.service seems effectively a part of the problems, it appears in android warning message he receives. It could be usefull to create a list of apps than could safely be remove, for fixing the adware issues, I will do it, but I certainly not doing it before some weeks, I don't have the phone right now.
Thanks for the IEMI trick, I didn't know than an IEMI could be delete so easily.

It is a typing mistake, I ment PC. When connecting phone to the PC with USB you need to remove the battery first (it doesn's say so in the instructions), because if the battery is inside the phone will start charging and connecting to PC like external drive and na Flash can't be performed. When formating and flashing with SP tool is done, than you can disconnect from PC, insert battery, and Root with instructions below through Recovery mode.
Here are a Root instructions
https://docs.google.com/presentation/d/1NJcDBkLk8zMwyv2BTqRjn2NB_ZOWKjP1fRpSVr44Oxk/edit#slide=id.p
This adds popup, and background ram eating processes are a common problem with cheap smartphones from alixpress. There are several "cleaned" ROM-s from PDA developers for Gretel A7, but I didn't want to risk because the phone is now working fine, no bugs etc. Only thing that is pain in the ... is a proximity sensor that doesn't work, and it seems to be a hardware issue, so i need to manually turn off screen after answering the call.
