thx i already found it, but cant download due to download limits.

lets start over: i sold a a820 to a friend, after 2 month it showed only blank screen with lit display.

but it shows up in usb devices and i was able to do adb reboots and so on. but no recovery and so on.

i found now that SP flash tool, but did something wrong, now i didnt have a lit display.

its now been detected as mtk preload usb device. as far as i read, thats still good. think i damaged the bootloader, so i need the entire flash, or at least so bootloader.

found now the entire flash on a polish site. lets see if that works :P

jeah it works !. but i still have just a lit display, but now hear the rom sounds. before i had cyanogen mod installed. looks like a display problem.

I'm using this rom: http://www.needrom.com/download/lenovo-a820-12/

Can I just over-install your Rom or do I have do do something with the repartition? Beacuse I used the Infrared's file to repartition and disable internal SD.

Thanks
[Miscellaneous Android Development] ovindigo:
Best ROM for Lenovo a820. THANKYOU... I Hope there is newer version of it.. Nougat maybe? :(
[Miscellaneous Android Development] cappa72:
You did it well. :)

The other possibility could have been the MobileUncleTools version (if your phone was a rooted one). (I updated the post#3 with pictures... and I plan to add pictures about how you did the flashing).

The scatter file contains information about the phone's partition, not about the content.

On your MOD v. 4.1 installed through TWRP the whole screen, after bootlogo, goes bricked - I see only artifacts and pixels...On 4.0 v3 all is ok.

Maybe it's cause install is through TWRP, I will check on CWM. Does anybody have this?

And lol - you didnt provide any link for proper CWM here - we have to find it on some hungarian sites...

Edit: I checked all of possible recoveries - all when I enter them - screen goes into pixels... I dont know what may cause it... Maybe it has something with preloader? I only upload recovery to the phone. I saw some fixed_bootimg etc. Dont know what to do. Anyway, I cannot your 4.1 MOD.
[Miscellaneous Android Development] cappa72:
Thanks for feedback.

It is really interesting and annoying that another owner in the Hungarian forum also reported this screen issue.

May the hardware changed?

I saved the original "Chinese CWM" (I would say it was not the real original, but I got this phone with this Chinese recovery), and it did not work for him.

I hope your hone works with as the phone (in normal way).

What is your current custom buils of your current kernel? 135? 138?

Until this question is not clarified, please do not use CP4.1 mod ROM, not any of the CWMs ! (It contains older kernel, the "130" one and could generate the same issue when you want to use you phone )
[Miscellaneous Android Development] cappa72:
Request for dumchar_info file

Dear Owners,

For clarification of some issues, I need your help.

I need the partition decription of different phones.

The really detailed one is the /proc/dumchar_info.

This can be accesses without root rights.

If some of you can post or link it, i would appreciate.

Thanks.
[Miscellaneous Android Development] LethalOne:
I checked your 4.1 ROM on all possible A820 recovieries - on all it doesnt work. Whats more - the only recovery that works is TWRP, all other when turned on, go into pixels on screen after any move in them.

So please clarify - what exact recovery must be used to install CP4.1? You managed to run it, so you must have used some recovery, that I didnt try.

Fortunately - I got back to normality, by putting back TWRP and installing previous version of your MOD, and now its all ok. I wasnt afraid, cause still I could install A820_S138_ru_mid, wchich is installed through SPFlash with "Firmware Upgrade" function, so even if recovery is crashed and unusable - you can get it working :)
[Miscellaneous Android Development] cappa72:
Thanks,

I would appreciate if you could share recovery.img and the boot.img of the S138_ru_mid rom. It could help me (and the others)

About the CWMs modified by me:

I used the S130 kernel for the CWMs (when I prepared them, only the S130 was available; I got this phone with this kernel), it could cause your failure. As I mentioned may the hadware is changed. For me all these CWMs worked (apart from the restoration issue.)

I also mentioned that other people reported this screen issue, which nean that slight difference there can be between the phones. Many people did not report this issue at the beginning.
[Miscellaneous Android Development] LethalOne:
Cappa, how is it going making working version of your 4.1 ROM? :)
[Miscellaneous Android Development] cappa72:
Nowadays I did not have enough time and I did not have this phone for 2 weeks.

Now I have got a new one, so I will continue the work.

First, the repartition has been solved, so the /data partition is 2.6GB; the "internal SD" card is disabled and the physical SD card is mounted as "internal SD".

The camera issue with green bars is decoding issue.

I will come back soon.

Thanks for your patience.

Etotalk rom is a ported ZTE rom and not based on official a820 firmware. I rather have a rom based on official firmware instead of a ported rom (mainly for compatible issues)

Etotalk rom has the best multi lanuage support at this moment.
[Miscellaneous Android Development] cacofonix3:
So, excluding the multilanguage, you suggest another ROM?
[Miscellaneous Android Development] benz0076:
No at this moment the best rom is the etotalk rom.

It preforms great and it has no bugs.

I am tweaking it at the moment to make it better.

There are some annoying little things in the etotalk rom wich need some work.

Hopefully i can provide you all with a good mod version of the etotalk rom just give me some time.

Sygic is working with GPS EPO and A-GPS + FasterGPS;

Osmand+ too, but you still have to wait a couple of minutes . . .
[Miscellaneous Android Development] cappa72:
Yes, sure. I want to.

About CP4.0 v4 -> the kernel is the stock S130, but it does not work on newer phones. If your phone was delivered with S135 version of the original ROM, I would not recommend that.

I am preparing the post, where I want to renew the information I gathered and explain the easiest way of the repartition as well.

And also, the cp5.x, where the aromainstaller will be used. This is the main change compared to the 4.x versions

Currently, the 5.0-v2 is only for testing purpose, with kernel S130 still: also not recommended, only for brave people.

For your information, when you remove the Galery2 and apply the GaleryGoole instead, the video playback will not contain green bars (if you record with GaleryGoolge; but still contains green bars, if you record the target with Galery2). But, and it is not so comfortable, the the video recording with GaleryGoogle is not perfect: when there is too much black on the target, the screen became black... The CameraMX (free and available on the PlayStore) does not do this inadequacy.

So, this is what I can say at the moment, I'll be back (I'm not a terminator anyway ;) )

It takes time.
[Miscellaneous Android Development] cappa72:
Updated 1st post

I would like to inform you that the repartition has been solved, see the 1st post.

[Miscellaneous Android Development] deaglecat:
Is it true that you cannot backup or restore ROMs if you have an Etotalk modded phone with their modded CWM version installed ?

If so, how can it be fixed. I don't want to rip off their ROM but I do want to try other ROMs and have the option to go back to the Etotalk ROM.

Thanks
[Miscellaneous Android Development] benz0076:
Yes its true but if you go to my thread and install the cwm recovery there you can make backups again.

Follow the guide but first delete the etotalktools apk and install mobileunce mtk tools...its the same app but etotalk disabled the recovery flash option wich you need.

Delete the etotalk tool app....its in /system/vendor/operator/apps and in vendor/operator/apps.

Reboot your phone and go to the playstore to install the mobileuncle tools and use it to flash the cwm recovery.

Look here for my thread and download the cwm recoveryhttp://xdaforums.com/showthread.php?t=2301212

Please, I need ACTIVATE my INTERNAL SD CARD (I use the script to disable internal SD card), if it was possible. Is there a script to do this?

Thanks.
[Miscellaneous Android Development] cappa72:
Yes, sure.

Here is a CWM script, which restores your original vold.fstab file.

It contains the original mounting points, so your internal SD card will be enabled again.

But after the repartition is only 14MB.

There's a way to set external SD card to be the default storage.

Why I have to do that?

The reason I have to do this is because I have to storage the game data and map data, the game will check the internal SD card for the data

as well as navigation apps.

This limited the data you can put in.

So, if I have to change the default storage to external SD card to read the data:laugh:

You need to change the CWM recovery to one, which really prepared for you phone. In the post #3 you can find how to install it via flashtool, or MobileUncletools.

For the Etotalk question: I have not seen that ROM, but in post #55 benz0076 describes how you can delete the Etotalk's blocking applications.

I hope it helped.

You can hide the signal icon for the unused sim by editting systemui.apk.

Yours the version 4.2
[Miscellaneous Android Development] cappa72:
So, the "manual version" can work.

I mean, if you replace the current /etc/vold.fstab file to a new one, you canhave your physical SD card mounted.

To have it, please do the followings:

download this A820-vold.fstab-disabled-internal-sd file, and rename it to vold.fstab

0, save your curent /system/etc/vold.fstab file to any directory as a copy.

1, copy the vold.fstab file into the /system directory.

2, give this file the right permissions (with e.g. root explorer, EX Explorer), like this:

3, copy the new vold.fstab file from /system to /system/etc directory (allow the replacement to the new file)

4, reboot your phone.

I need you feedback, if it works.

I managed to change the text in the file as it is in the new file: that means changing the #dev_mount sdcard /storage/sdcard1 emmc@fat into #dev_mount sdcard /storage/sdcard0 emmc@fat

Right?

Then I reboot it and still no changes :crying:

Thanks for that rom

Hi Cappa,

Many Thanks for that rom, it works really good.

I had a Etotalk rom so :

- I remove Etotalk application

- I install Mobile uncle

- Update CWM

- Install the new rom.

- After that i wanted the new memory partition, so :

- I install the two zip file from CWM.

- It works great but if I do a recovery of a backup after that things didnt work anymore, so I kept with no recovery.

- I put Gapps of V3 (tricky to find it in the first post)

- GPS with EPO and A-GPS has a quick fix (less than 30s)

I have just the problem of green bar on video.

The problem is not on recording, but with some video playing (including the one I record), the colors are fanzy and I have a green dot line.

For example I have it on Street Fighter 4 (SF IV HD) introduction video (see files below).

Do you think you can do something ?

[Miscellaneous Android Development] cappa72:
Having more /data partition size, your "internal" SD has got less size.

With other words, your "internal" SD card is added to /data partition.

If you use the CWM script to have repartitioned internal storage with the size of 2,7GB (for /data partition), your internal SD is around 14MB.

For this reason it is good to disable it (do not mount the 14MB as an available partition).

What do you mean by "usb storage nothing?".

Have you checked that your physical SD card is visible?

You can restore your storage state to the factory one, see post #75
[Miscellaneous Android Development] dragimacak:
Green Bar

You are right.

VLC doesnt run smoothly with camera recorded videos.

But if you choose normal quality Green Bar is gone en you can record and play your video's without a problem.

If you are professional and you need high quality video's, than you shuld use a professional video camera ;)
