What are the differences between your rom and Wolfgang 's?
[Android General] kkffiirr:
in this firmware somewhere laid signature verification, some applications from other drivers simply are not seen, or return to the native kernel, or there H2 for N850

This is a quote from some of the experts in the Russian forum translated in Google translate.

Is there anything to do to bypass this verification?
[Android General] a.marduk:
i think u have to build the kernel from scratch :D

if you're looking for another source for custom rom, try my local facebook group

IMO S89 group 1

or IMO S89 group 2

or u can try walton primo fb group

Walton Primo H2 group

as far as i know, some roms still have bugs here and there,

i think amoi N828 missing the power chip for OTG, maybe using paralel OTG cable? (one to phone, one to power source, and one to the usb device) ... it's just maybe though :D
[Android General] jaydvn:
They're have no differences, but the sms auto active warranty. In other country, its ok and no problem, but in Vietnam, its very annoying. I don't want to lose money each time I factory reset my phone. It's really crazy.

---------- Post added at 11:34 AM ---------- Previous post was at 11:28 AM ----------

I don't think so, I think we need a new kernel to active OTG support, I use OTG test in Engineer mode (access via Mobile Uncle tool), and phone was give my Flash disk power, but the kernel don't allow us to read and write data.
[Android General] kkffiirr:
AFAIK, the people from mobileuncle forum has made progress with otg support, they said it will be published after more tests.
[Android General] graal:
Please anybody who uses Walton or Wolfgang based ROM tell weather you have a problem with assigning the ringtone.

The matter is that it's played always a ringtone specified in build.prop file.
[Android General] kkffiirr:
Using Walton, you have to delete the default ringtone
[Android General] graal:
Thanks. I know at least four ways to fix the problem.

Is the issue common? That is a question. Such a little survey :)
[Android General] a.marduk:
yup, it's the same for me here, 4 ways? what's the other 3 :D
[Android General] graal:
As I see in your signature you're using Wolfgang ROM. Could your replace your Phone.apk with modified one and check whether the problem is fixed.
[Android General] mistraller:
For Wolfgang users: Dutch people are also reporting problems with changing the ringtone on the original rebranded phone. Ambiance Technology is aware of the problem.

I have another problem on the AMOI rom which is anoying: After a reboot, all apps which should autostart, don't autostart (That is at least; tasker, dropbox-for photo upload, NoLED) Maybe this is caused by the same problem of not getting read/write on system.
[Android General] graal:
I used to manage auto start with AmoiTools.
[Android General] kkffiirr:
Is there an option to get a boot log like in Windows? I want to know what prevents the system from start when I use n850 kernel
[Android General] jaydvn:
Did you mean ADB logcat?
[Android General] kkffiirr:
i will try.

thanks.

btw, what is the apk that is reponsible to the warranty issue?
[Android General] mistraller:
What is amoitools? Can't find anything on it...
[Android General] graal:
This is a preinstalled apk in official AMOI ROMs. If you're using some custom ROM it could be removed.
[Android General] mistraller:
Well, I'm still on stock v5.6 but I can't find anything like amoitools...
[Android General] kkffiirr:
okay, i tried doing logcat in a good boot (with the original kernel of wolfgang version) i have it.

then i flashed the N850 kenel files (lk.bin and boot.img), no boot, and no log.

then i tried to flash only one file at a time, when i flashed boot.img, i got no boot.

when i flashed lk.bin, it booted, but still, can't connect to camera.

now what i think about is to make a cross rom combing the Vietanamese rom and Wolfgang, since the Vietanamese rom can boot with the n850 kernel.

i can still use an updated n850 kernel if someone will found a rebranded version of N850
[Android General] jaydvn:
It's Settings.apk, I've decompiled it, deleted all smali files about warranty, but after that, I can't recompile APK back. I think warranty only works in Vietnam.

Are you trying to get Wolfgang ROM fully working on your N850?

lk.bin is uboot and it contains camera and LCD drivers. I've tried many devices base on MT6589 and they also have video recording issue, I don't know why but it's very annoying. And I hate to record video in low-light with N828, everything will be more darken.
[Android General] graal:
Well. it's little strange.

Just in case, here is a link to AmoiTools from v5.6 ROM.
[Android General] kkffiirr:
That's strange, because I could use the n850 ' s lk.bin, but as I said, still no camera.

Is the logcat from a successful boot will help me why it refuses to work with n850' s boot.img?
[Android General] a.marduk:
i've resolved the problem by changing lines in build.prop

ro.config.notification_sound=
ro.config.alarm_alert=
ro.config.ringtone=

ps : seavovk's version didn't have this problem...

can u post your boot.img... i'd like to take a look at the ramdisk section (comparing it to wolfgang boot.img ramdisk)
[Android General] kkffiirr:
You can find it here : https://disk.yandex.com/public/?hash=AQoj5fsCdnsqAq6OIrj126XNQm7t5jKBg+nabuPWdLM=
[Android General] graal:
It DOES have the problem.

I just asked for testing modified Phone.apk for my custom ROM.

I don't like anybody's ROM version with replaced original apks for no reason.

And so I've made self-cooked ROM. Deoxeded, with original content (patched a little), gapps updated, rooted, aroma based.

And I don't mind if anybody will flash it and maybe write a word or two about it.

Link to download
[Android General] mistraller:
I'm sure I've never seen this icon. Maybe it is not there, because the phone's root ability is not correct. (I can't get RW on system), tried several options. Does AmoiTools need to be in system?

... I really need to flash this phone.... :)
[Android General] jaydvn:
I'm on Wolfgang too and I've tested your moded phone.apk, it works perfectly! I can change ringtone for each sim card without touching the build.prop file. Thanks!

Your port patch is'nt enough to make rom work, I'll make another patch for you.

[Android General] kkffiirr:
What are the changes you made?
[Android General] jaydvn:
Add some files, lib, xml... Etc... Repack boot.img with Walton Ramdisk.
[Android General] kkffiirr:
Well, camera still not working

Unable to connect to camera
[Android General] a.marduk:
i've looked at your file, it's the standard camera patching, i don't know what went wrong :sorry

maybe you can find your answer here

wolfgang rom is really similar to acer v370 ver.030 jb 4.2.2 rom, just by replacing the boot.img with the patched wolfgang boot.img, the rom can boot, and all the sensor and hardware is working (no files changed, can't charge on off state), i even try to flash the original acer boot and system.img, and it booted :D but with display error...
[Android General] kkffiirr:
Well, until now, using the file that I linked before, I was able to use any n828 rom on my n850

---------- Post added at 12:19 PM ---------- Previous post was at 12:03 PM ----------

Enviado desde mi AMOI N828 mediante Tapatalk
[Android General] a.marduk:
try this

repack boot/recovery img into kernel and ramdisk folder

if you read the previous post, there are some link for roms, i think most of the roms are in multilanguage...
[Android General] kkffiirr:
maybe i can repack the wolfgang boot.img, and replace the camera driver.

it might work

which file i should replace?
[Android General] a.marduk:
init.rc

but your boot.img is already patched...

#Camera
chmod 0664 /dev/camera-sysram
chmod 0664 /dev/camera-isp
chmod 0664 /dev/camera-pipemgr
chmod 0660 /dev/kd_camera_hw

chmod 0660 /dev/kd_camera_hw_bus2
#chmod 0660 /dev/FM50AF
#chmod 0660 /dev/OV8825AF
chmod 0660 /dev/OV5647AF
chmod 0660 /dev/CAM_CAL_DRV

chown system camera /dev/camera-sysram
chown system camera /dev/camera-isp
chown system camera /dev/camera-pipemgr
chown system camera /dev/kd_camera_hw
chown system camera /dev/kd_camera_flashlight
chown system camera /dev/kd_camera_hw_bus2
#chown system camera /dev/FM50AF
#chown system camera /dev/OV8825AF
chown system camera /dev/OV5647AF
chown system camera /dev/CAM_CAL_DRV

amoi n828 use /dev/OV8825AF (# is removed)

and i think N850 use OV5647AF

so it's already patched... the camera probs is not coming from the boot.img

but you can try using your stock boot.img
[Android General] kkffiirr:
Stock kernel doesn't work.

I think I should make as little changes as possible.

That's why I want to try to modify Wolfgang 's kernel to work
[Android General] kkffiirr:
Btw, is this the place where I can disable the annoying auto zoom in the video camera?

and three more questions:

1. what is the role of lk.bin file?

2. where in boot.img i can find an option to flip the functionility of the touch buttons? (in N850 the left touch button is back)

3. i found more entries with the camera, in ramdisk files and in init_project, and meta_init.rc, what are them, and what is FM50AF?
[Android General] a.marduk:
[MENTION=5439748]kkffiirr[/MENTION] , i'm really new to android, don't have java skill or linux , just a regular window user using the power of google.. :D

maybe there're fellow members here who can give the explanations

:cheers
[Android General] jaydvn:
1: lk.bin is uboot and as I know, it contains cameras and display driver and some boot instructions that I don't know.

2: boot.img does'nt contain key layout, it's in vendor or xbin, I don't remember and tell you later or you can find it in my patch I gave you (extract zip file and search "key")

3: I think they are codes to control the camera and don't know what exactly they are!
[Android General] kkffiirr:
Thanks for the answer.

I know for sure that boot.img control the key layout because I tried this once, when I switched this file the key layout changed.

Inside boot.img there is a binary file named kernel, I think it may have to do with those problems, will it be wise to put the n850 kernel in there?

Sent from my AMOI N828
[Android General] jaydvn:
Ah, you're right! key layout is in boot.img

Sure, you have to put N850's kernel in there then repack boot.img.
[Android General] kkffiirr:
I hope it will work. I hoped that the camera will work if I only change the init files, and to resolve the key layout using xposed

Sent from my AMOI N828
[Android General] kkffiirr:
Okay, I successfully patched the boot.img, camera works properly.

Only problem that the stock camera app isn't present, and I have to install 3rd party camera app.

Is it has anything to do with this?

You need to make a jumper between the two pins on the board in order to work!There is no OTG out of the box! Check video comments.

it turns out that the stock kernel already support OTG, just need to solder those 2 pins on the board to make OTG works.

Now my question is this, there are 4 unuse pin there on the picture from [MENTION=3267736]nikosst[/MENTION] , so "maybe" there are two more pieces of hardware that is supposed to be there (either resistor or diode or whatever). From googling amoi N850 , it says that it support OTG, and "maybe" N828 and N850 use the same board. CMIIW

May I Have My Phone Bricked?

Hi there,

I have the following problem and would be very glad for any help:

My internal phone storage went full and i decided to try a custom rom. i installed cwm using MTKDroidTools and everything went well. I tried three roms and two worked well. However then i did something stupid. As i dont need the internel sd card storage i tried to get the internal storage repartitioned. therefor i downloaded SP Flash Tool. I dont really remember what went wrong, but my phone does not boot anymore. Neither to usual android nor to cwm. the only way i still can communicate with my phone is the mtk preloader. Now i have to get a working operating system on my phone using the SP Flash Tool, right? Does anybody know, how i can do that?

Thanks in advance

---------- Post added at 07:06 AM ---------- Previous post was at 07:02 AM ----------

I think the best solution for you is looking for a N828 rear camera and replace the one come with your phone.

N828 and N850 mainboards are exactly the same.
[Android General] kkffiirr:
Seem crazy, with a risk of killing the phone, there could be some differences in caps and resistors that are not placed.

And yet, I want to check how much the camera module cost, can you please tell me the exact model of the camera?
[Android General] jaydvn:
I don't know how much does it cost and it's model, but I know that mainboards are the same, cos' my friend's N828 mainboard was replaced by N850 mainboard and everything works perfectly... I can take pics of dissasembling for you because my N828 is out of warranty, you can compare with yours.

I bought a battery from MBS and it's brand is AT(WolfGang), I believe MBS has N828 8Mpx rear camera module but don't know how to send it to you.

I found the camera is ov8825, I can get it for 5 usd and 15 for shipping, not so cheap...
