Hi everyone,
Im using FutureRom B175 right now. I want to change my custom rom to stuck because of some reasons but i can't install stock rom. I suspicious some reasons why it doesnt work well, maybe xda can help my problem.
First of all;
Bootloader unlocked
Recovery, TWRP & ERecovery
Root, Magisk thanks to custom rom
My thoughts:
1 - My phone was VKY-L29C636 when i bought it. After installing future rom B175 it changed to VKY-L29C432. Maybe data files changed it, i dont know
2 - I'm using this rom -> VKY-L29C636B172 Full-OTA. Firmware Finder says it available for you when i check availability from IMEI page. This is link:
http://pro-teammt.ru/firmware-database/?firmware_model=VKY-L29C636B&firmware_page=0
Downloading update.zip and extract it. Copy update.APP data to my SD Card's root into dload folder. Pressing Vol +, Vol - and Power button. Installation page opens but when its %5, it says software install failed
3 - I tried this method too. What if i use VKY-L29C432 Full-OTA?. I tried it as i mentioned above. It returns this same error.
4 - I saw some text about dload method. Some people say that we should use our SD Cards in FAT32 formatting mode. But i can't send my files into FAT32 SD Card. Because update.app's size is more than 4GB and FAT32 doesnt give any permission to do it. So i had to stay in NTFS format.
My questions
1 - Should i relock bootloader before trying to install stock rom with dload method?
2 - Should i use VKY-L29C636 or C432 update files?
3 - Which format method that i have to use?
4 - If format has to be FAT32, how can copy my update.app into SD Card?
5 - If i send my phone to service, do they say to me "it's mainboard has to change or smt. else"?
Please help me. Im working on it for 2 days. Thanks
