I bought SM-C7000 and it was on TGY (HK) version with Play Store. I love to root my Android phones, found a post on XDA, and was able to root, install Xposed, etc. One night, I thought to remove the root because Xposed modules were not working well. So, I unrooted the device in SU. Restarted and then the accident happened. My device was bricked. I tried to install the HK version from Sammobile but in vain. Always got auth error or invalid data error showing data is too big. Then I tried Smart Switch and downloaded it by entering the model number and the serial number of my device. My phone booted. But when I used it, it was now the CHC (China) version with no Play Store. Then I again started searching. Again file big error. Searched the net and found that it was a partition error and I need a PIT file. But after searching, I found that the PIT file for both TGY (HK) and CHC (China) are the same.
For Odin, the solution is to first flash only the
ap file and it will give the error at userdata ext 4. Remove mobile and again, put it into download mode, and now flash
csc files only. Remember not to touch repartition. And untick reboot also. After flashing, reboot into recovery and wipe data and cache partition.
Now your phone will be the TGY (HK) version with Play Store, etc.
