Seeking help directly from developers as posting in general section has not yielded any help past few days.

I flashed ZCKPL Chinese stock rom from here

Rooting was quite a trouble as 2 methods of rooting both were breaking some of its features hence a member on xda [MENTION=4197544]chongns[/MENTION] ported a fresh CF root & that finally worked.

Since then I am having a strange problem & have flashed & re flashed over 30 times in various combinations but nothing is solving the problem on ZCKPL.

Summary of the problem

Whenever I call a contact or they call me, their names are not showing up and only numbers show as if they are not in my contact list (And I don't have a clue on who is calling). But if I check my call logs later, I can see their number along with their name. I want to see their names while they are calling. How do I do it in my case? As I recall there was some GB firmware it has this issue but was sorted out too.

I had backed up my contacts using super backup & restored using the same, on earlier many times of zckpl installs & never faced any issues with other rooting methods they had other issues though but not this bug.

Ganesh CF root does not work at all for ZCKPL

Bam kernel v15 breaks call recording

VurrutKER_stock_v9.1 breaks wifi

Amit Bagaria CF universal root breaks wifi,

A brief summary of resolutions I tried but failed every time

1. ZCKPL factory reset without formatting the internal card, this keeps the CF root rest all apps go away, signed to google account it started sync then installed super backup> restored contacts they give the same problem.

2. ZCKPL factory reset + formatted the internal card, all aps including CF root gone then signed to google account it started sync then installed super backup> restored contacts they give the same problem. (This was to root out if Cf root has created this issues or not)

3. Installed DDLF full rom with 3 files > then without adding any google account restored the backup from Super backup, all worked fine on DDLF2 no problems now all contacts name show when number is called.

4. DDLF2 factory reset + formatted the internal card > flashed ZCKPL then added 1 phone contact & called it works fine on ZCKPL, then the contact called that too worked fine. All this while no goggle account added as yet.

5. ZCKPL factory reset + formatted the internal card once again then without adding any google account restored the backup from Super backup, all contacts show but when i call they don't show calling number, when someone else calls they still don't show but call logs show them all.

6. So at this step I exported contacts to external SD card using contact import/export to .vcf file.

7. ZCKPL factory reset + formatted the internal card once again then without adding any google account restored the backup this time by importing them from .vcf file(no super back this time) but the problem remains as it is called number does not show at all where as on stock zckpl if I add manually then it does work as usual.

8. ZCKPL factory reset + formatted the internal card once again then CF root applied I manually added contact & called surprisingly the called number now does not show. Deleted the contact & imported from .vcf file & contacts show in contact list but when I call a contact they don't show any name of the called person.

9. Installed DDLF full rom with 3 files > factory rest+wipe data

10. then once again Installed DDLF full rom with 3 files > factory rest+wipe data

11. installed ZCKPL added a contact manually asked them to call me it works fine

12. applied the new CF root & flashed the gapps in recovery

13. tried calling the same contacts now the name does not show

so something wrong is happening with gapps/ google account & CF root

14. This time I was advised by [MENTION=4383421]SikanderKeynes[/MENTION]

15. Installed DDLF full rom with 3 files > factory rest+wipe data

16 installed ZCKPL + CF root & restore contacts with mybackuppro.

This time I took a backup from google contacts & deleted all contacts from my google account then followed the same procedure, even then it fails the same way.

So I am now getting to believe that CF root right from amit baragia version may have some bug which is indeed contributing in some or the other way in displaying the contacts name.

I cant find the code to change CSC to INU its set to CHN that might be one of the issue.

So the finding concludes the following.

1. CF root may or may not have anything to do with this bug,

from steps 2-7 all this while the phone was not rooted at all

2. Google sync is not creating this problem as I didn't even add any account from step 3-7

3. Super backup could be creating some issue the format in which it does the backup, which has then been inherited by other backup methods.

4. ZCKPL itself without root does not show this problem if I add the contacts manually

Now I have a kies backup too but I really don't want to install that stupid software & mess my system, its just a pain whenever I had to deal with it. So I rather prefer that I add contacts manually which will take me many days to do so as there are over 2000 contacts.

Can any of experienced developers help me to sort this problem, 1st we need to find the source of the problem & then you may need to mod some file/setting to make it work correctly.

Looking forward to hear from the developers.
