Can we take the rom from 4044 and put it on our devices
[Android Q&A, Help & Troubleshooting] outlawman007:
:(

no, the signatures are different, and the hardware is not the same, the only phone that is the same as ours is 4300, bit it has 4.0.3 so it's a downgrade, from our 4.0.4.. if someone would port the rom, then it would be possible.

Hello!

Is there even a possibility for our phone to get JB? any version? Couse more i look, the more i see that, everyone has stopped working on this phone...why? it's a good phone...and it could run JB. Thanx for the answers. I realy hope someone can do something,
[Android Q&A, Help & Troubleshooting] baluuu:
There is no kernel source available so developing a jb rom is close to imposible cuz there is no starting point.

[Android Q&A, Help & Troubleshooting] baluuu:
Im currently using LeWa OS from here http://4pda.ru/forum/index.php?showtopic=464688&st=940#entry26237909 I get a full day of heavy usage and 2-3 days battery when im only using the phone for calls and messeges (lots of messeges and ~hour call time). The boot.img of the rom is eddited to be 500 min 1000 max ondemand and has added init.d enabled. There are also moded stock roms on that forum but i like lewa better. If you dont want to change the whole rom you can probably try and flash the boot img only should work with all stock roms too. Other way is root and install no frills to set the governor to ondemand but the moded boot.img seems to kontroll the scaling much better. Hope i helped somewhat :)

Download this pack of original stock apps, install prestigio installer again, hopefully you have an backup with CWM so you can install it. After installing try to hard reset it and it should work. It worked for me as i realised that wizard always stops when you should get the apps for install, for which is prestigio installer responsible. good luck

[Request] Complete stock ROM?

Hi, so I'm new member in this website, but i've been here for a long time searching for stuff.

But now, I have a problem with my Prestigio PAP4040 Duo.

So, i've rooted it and i've got a CWM Recovery. I had a backup, but somewhy backup got messed up and doesn't recover /system.

I've been using Xposed tools, and it got messed up, soft-bricking my smartphone

Later, i've found MIUI for this phone, which works fine and stuff, but I miss a lot of features from stock ROM, for example, scheduled power on/off, which really saved me a LOT of battery life. So, I want to get complete stock ROM for this device (preferably from service center), but all the links in this topic are dead. All links i've found got me redirected here.

P.S. Yes, i know how to flash ROMs, all I need is complete stock ROM.

Thanks.

Will there EVER be Jelly Bean for this?

Is there anybody working on this device?I am so annoyed with the current OS:

-Extreme lag & irresponsiveness

-Generates huge thumbnail files(Solved)

-Had to root it in order to remove "PrestigioWizard.apk" (The one that Force Closed)

-Unable to handle basic operations such as watching a video,browsing, etc. (Note that I've removed ALL bloatware)

-LeWa is utter sh*t,looks extremely ugly and "Chinese"(Unfortunately,it's probably one of the only ROMs for it.)

-Random reboots and battery drains (Drops to 1% after reboot sometimes...)

-No Google Now support. I've downloaded & installed Google Now through a mod,but it is really outdated.

Will there EVER be any jelly bean release,at least buggy...but usable?

Please guys! :fingers-crossed:

If a JB rom ever appears on here,I will mod it. :D

New update

There is an update to 4040 on their servers.

OTA don't see it but there is one ;)
[Android Q&A, Help & Troubleshooting] kar10s:
That is a good news! Can you give us links for it so we can get it and install it manualy (without OTA)?

I'm asking because on their oficial download site ( http://yf2.value4it.com/Service_Files/Smartphones/PAP4040/ ), there is nothing new. Last version there is 1.0.10 which we already have :( And we all know it is full of bugs which they refuse to accept as theirs...:(
[Android Q&A, Help & Troubleshooting] WRaven512:
:) and there never will be any update :) updates are via ota only but i did trace their ftp server here is ip 176.9.25.204 login blank & pass to

but there is only updated libbcc.so.sha1 and some ****y usles apps and new 2nd boot animation
[Android Q&A, Help & Troubleshooting] kar10s:
Um, what is that you did? Or is there something missing in these pictures?

Why do you think so? For 4300, every update is there and the same aply to many of theirs tablets, just take a look...

Anyway, I will check your info, thanks for it...

EDIT: Ok, just chceked it, the FTP:IP you gave us is just public FTP access to the website I was reffering to. The visible content is not exactly the same but most is. And yes, there is one file that looks like it is update for 4040 to newer version, but it is a bit hidden... I will check it and let you know... (probably tomorrow, now I am going to bed)
[Android Q&A, Help & Troubleshooting] WRaven512:
internal storage 1,17 GB before ~600MB This is \Data

Phone Storage 1,43 GB before 1,99GB \SDcard

;)

but all updates for 4040 are on this ftp in dir HQ

latest is PAP4040_V10-13_package_20121226.zip

maybe there are different teams working on 4040 and 4300 in diffident places...
[Android Q&A, Help & Troubleshooting] kar10s:
ok, do I understand correcttly that you just changed sizes of internal partition for this? Can you give us some more info about how is it done?

I personaly would be interested in moving ALL the free space form internal storage to data (and removing the internal sdcard alltogether). Curently I am using a little hack which changes location of internal and external sd cards (simple renaming in /etc/vold.fstab), but this looks interesting...

Yes, that is exactly the file I was reffering to. Also I think, that the FTP is actualy used for development, and that might be why nor OTA neither web can display the file, because it is not yet finished (and thus moved to correct location) - from quick examination, I think there are only newer version of installed apps, but I will know more later.

EDIT: Oh well, seems I can't sleep, so...

I just aplied the update.zip from that archive... it looks like it is working. let me check all the stuff (did I miss something?)

* inceased the FW version to 1.0.13 - check

* is rootable with the old method? - check

* recovery modified for never version - check (why is that? oh well...)

* check if "framework(s) bug" is fixed - negative (not fixed)

* check for any workaroud for this bug - negative (maps are not accesible from other aplications using them - causes app crash)

* check if "com.google.android.gms" can be installed - negative (still the same error)

* configuration of kernel/cpu governor changed - negative (governor set to performace, CPU frequency stays 100% (1001MHz) no matter what...)

sumary:

whatever it did, it is prety useless - either it is a WIP or bad joke. I will reflash 1.0.10 back and wait for official OTA (if any)

btw this ftp address i trace while the ota was downloading update
[Android Q&A, Help & Troubleshooting] kar10s:
Thank you for the link (hopefuly the goggle translator will not change the meaning of anything important) :fingers-crossed:

EDIT: just great... that will be fun, I think: there are two diferent lines, and (I belive) one of them is saying REMOVE internal SDcard, while the second sais DO NOT REMOVE sdcard, but google translates both of them as REMOVE. oh well...

And for the OTA: Well, yes, I believe you and thank you for it. Its just that if it is real final update then I am really disapointed. So I hope it is not...;)

EDIT2: Ok, I have just experimented with the script to remove the internal SDCARD. It seems the script itself is fine, but the signature has failed and I had to use CWMR to flash it. When I was done with it (no error), I received warning that the system may replace the recovery (which actualy has happened as I found out later) - that was totaly new for me - it did not happened before, so I believe it was the result of the update to 1.0.13.

And also the phone failed to boot after that. I tried on stock 1.0.10 (well, I had to do it all again: flashed 1.0.10 firmware, rooted, flashed CWMR again), then again tried the script, but it failed again, so I believe there is some major bug somewhere. Seems i will do the same as you (but well, I think I wil shrink the interal SD to 100MB or something like that and then switch switch it, or maybe even switch it off by not mounting it :)

Sad thing is, that I can not report that failure to the author of that script (well, my knowlege of russian language is limited to google translator, which also is not too good :( )

You do not know (by any chance) any way how to modify the system.img so we (or I, or anybody) can add root directly to it, do you?

there is no way to full remove this sdcard, after adding this mod i have hanged vold file then i unmoumt it and camera stop working
[Android Q&A, Help & Troubleshooting] kar10s:
yes, I thought so much... I was just triing the other option because it just might worked (there is not that much difference in the file system), but the system probably has some reference to the internal card somewhere (which explains why the camera stopped working for you when the internal area is unmounted)...

well, again, thanks for the information, it sure saved me some time, so I will just stick to the original plan to shrink it as small as possible and then swap it with real SD card (the last part is working for me now without any problem).
[Android Q&A, Help & Troubleshooting] kar10s:
I did it! Now my phone thinks that my internal sdcard with size of 50MB is external and my external acts as REAL SD card in any other device and moreover, I now have 2.2 of 2.5GB free on my internal storage!

Only bad thing now is that the camera now can not save images to the SDcard - it looks like it has hardcoded device identificator for internal SDCARD and reads the location of EXTERNAL from vold.fstab or some similar location, which in my case means that even if I switch the storages insade the camera, it still points to the same location. Or is there another explanation? Oh, and by the way, even when there is 50MB free on the internal (well, external now) disk, the camera stil complains that the SD card is full amd refuses to make any more photos. I will try to solve this with DirectoryBind for DCIM folder, but that is just a stupid workaround rather than solution to the problem, oh well...

EDIT: Yes, the Directory bind http://xdaforums.com/showthread.php?t=1410262 did the trick - I have now DCIM mapped to real SD card as it should be!

Thank you for your assistance WRaven512!
[Android Q&A, Help & Troubleshooting] WRaven512:
maybe a silly question but did you change default write disk settings in system >memory ?

did youe edit 2 vold files ?

mine is saveing pictures corectly on phone strorage (real sd card)

any way there is a one useful mod

in /system/usr/heylayout/mtk-tpd.kl

change line

key 217 SEARCH VIRTUAL

to

key 217 CAMERA VIRTUAL

and you will have a buton to tak instant photos in camera without AF each time

Set AF touching on it in camera and af will be all time while touching old search button and if you touch it and wait it will power on camera :)

[Android Q&A, Help & Troubleshooting] kar10s:
What do you mean? I restarted the phone and no other apps have no such problem? And if you mean if I changed settings for preffered storage medium, then no, I did not - I expect the SD Card to be swapped completely (I even moved (duplicated) the content of these to awoid problems when the change takes effect.

Hey! that is a nice trick :)

well, yes, there is a difference - I wanted to have extrernal in place of internal, so I changed vold.fstab

dev_mount sdcard2 /mnt/sdcard2 emmc@fat /devices/platform/goldfish_mmc.0 /devices/platform/mtk-sd.0/mmc_host

dev_mount sdcard /mnt/sdcard auto /devices/platform/goldfish_mmc.1 /devices/platform/mtk-sd.1/mmc_host

which is diferent to your setting and for the vold.fstab.nand - I did not touched that file, so I have there only this:

dev_mount sdcard /mnt/sdcard auto /devices/platform/goldfish_mmc.0 /devices/platform/mtk-sd.1/mmc_host

And now I am confused, what is the difference between yours and mine setting, but I think, the only diference is in the vold.fstab.nand file, I will try to change that.

BTW: does the mount name have any real inpact on the system? (that is the only difference between ours vold.fstab file

EDIT: yes, you were right! The problem with the camera WAS caused by the vold.fstab.nand - when I changed it to

dev_mount sdcard /mnt/sdcard2 auto /devices/platform/goldfish_mmc.0 /devices/platform/mtk-sd.1/mmc_host

it started working fine. Oh and that is also the answer to my question - the mount name has some importance (although I do not fully understand it... :silly:)
[Android Q&A, Help & Troubleshooting] WRaven512:
it is worth to try also remane .nand because there is no need to use additional app to map DCIM

on clean soft i had a 2 DCIM folders one one /mnt/sdcard and 2nd on /mnt/sdcard2 now i have it only on /mnt/sdcard (microsd) and any other dir from android system is not created on /mnt/sdcard2 (old phone storage) i have a backup only

And it seems to be working fine...
[Android Q&A, Help & Troubleshooting] t830mc:
Greetings everybody,

I'm very suprised this topic came to life, as well to see horza joining.

Therefore I would like to share two really annoying bugs with you here, as well as couple ideas.

1. UI Stuttering and laging, especialy in low light envirnoments

At first I tought it was lack of memory and the fact that 4040 has only single core CPU. But I remember my older phones also had single core CPU and 512MB of RAM didn't have this issue. I found this issue is maniffested only when autobrightness is enabled (autobrightness bug). My workaround is disabling autobrightness and installing some custom autobrightnes app (in my case Lux Autobrightnes). Downside you cannot control screen brightnes in video players.

2. Stuttering on autorotation in some cases usually related with video playback (youtube, mxplayer)

For this I have no solution (acctualy never spend any time to see what could causing it), but it doesn't bother me so much

3. Video lag when playing video using HW acceleration

For this I have no solution, but it doesn't bother me so much

I think 2 and 3 are related

-------

I'm having two ideas in mind. First to change the phone for some other device with better custom rom support (CM or else), or (second) to spare some time to create barebone / optimised custom ROM based on stock with:

- bloatware removed (we could discuss the list of apps we can freely move to some other folder, for later usage)

- deodex (to add battery percentage inside the battery icon, everything else I'm not interest as a default theme)

- gapps updated

- bugs addressed (as much as possible without source code / workarounds etc)

- apply speed and power usage optimisation

- optimise UI behaviour (I hate this kinetic scrolling setting, it stretches like a chewing gum, touch screen optimisation)

For further development kernel source is needed and expertise which I don't posses regarding porting etc.

And one more thing before I complete my tought. I've found kernel source for huaqin77 (i think 4040 is huaqin75 (6575))https://github.com/icevoux/kernel_mediatek that someone willing and more skilled can look at. I've skimmed through source code and see that 6575 as well as 6577 is covered.

These are just my 5 cents.
[Android Q&A, Help & Troubleshooting] kar10s:
Hi there, and thanks for your ideas Here are my thoughts about some of them

This is (as you say) most likely caused by the "automatic brightness setting", as a lot of people complains that when the display brightnes is set that way, the lagging is there, but only from time to time, not always. Probably it depends on how bright the display actualy is. On the other hand I did not noticed any lagging, most probably because I do not use the "automatic" option and I have the bightnes set above 60% (two "dots" highighted)

Well, I have no trouble with playing videofiles, so I suppose the problem might be in your videoplayer, or maybe some backgroud process?

Well, here I am not syure what are you triing to say, Is it that you do not like the phone, or that you want it to be tuned up?

And moreover - are you going to do something of that optimisation you are speaking of or are these just suggestions about what should be done?

I am asking, because, I was having similar thoughts about modding the rom, but (sadly) my experience with this kind of things is not realy great. And also I did changed my job a few days ago, so now I do not have realy much free time for playing with the phone.

I would certainly love if somebody would be able to (at least) mod the rom the way you suggested. Well, not everithing is necessary for me - root (I hate rooting after each flash), gapps, fixing (or adding) google play service and batery indicator would do for me. Ok, maybe partition resize option would be also great.

I was thinking to do some of this thing myself, but I found I can not access (open) the original image files, and as I mentioned, now I do have a very little time, so I do not think I will be able to look into it any time soon. But I have noticed on some russian website, that there are some people who are actualy modding roms for MT657x, which I was going to give a try, but I had not yet the time.

EDIT: ok, I have tried to mod the rom for myself, and after two days of experimenting i managed to do something partialy useful, but sadly it alsways results in bootloop (for now). - even when I do not change anything :(
