Thank you for your comment! We should keep in mind this clone then.

If there is any resources for this one please publish links (to e.g. FW's, discussions, etc.), so people could look around and exchange infos.

Konka as long as its contractors, hide resources for the platform including sources that directly violates GNU/GPL open-source license requirements. Anyone can claim abuses (to Konka, Panasonic, other OEM's and/or participate in an unofficial resource collecting here and other appropriate places.

Glad to here TWRP is working OK and helped you! Greets from Russia to India! I've never found Indian boards where this device were discussed. May be they talk in Hindi, I don't know. There should be Indian users of this device and they should discuss it somewhere, so please connect them to this topic if you can for a free info/resources collection/exchange. These forums is a central place in the world on the theme. Thank you!

I can just guess why the custom ROM you've flashed stuck your phone.

It would be whether some occasional failure during flashing/starting, whether some incompatibility between Android system firmware and Modem firmware. There are different frequency bands used in a various countries. Russian band list definitely varies from the one in India. That's why it always better to avoid flashing modem FW/data from other regions w/o engineering knowledge and experience in the area of modem-related problem fixation/adoption. Some Android/modem FW pairs may be significantly customized, so the particular modem FW's may become incompatible with a particular Android system images (being both for the same HW platform). Try another ROM's (having a full flash backup of your device) or explore logs, etc. to find the place of failure.

Sure there is a way to fix these problems, however it could be complicated for the novices.

Some people in Russia reported they have successfully cross-flash Panasonic T45 FW's to the MTS Smart Sprint 4G devices.

I should note Panasonic T45 FW's, I've posted links to above, does NOT contain modem FW images so it is definitely impossible to reflash other device's with a Panasonic modem FW from there. It would be nice if someone will find (or backup) [fresh] modem FW's, full images and other resources missing or obsolete. There is also no NVRAM images for Panasonic yet nor images of any other "secret" partitions too. However these data could be very important to repair bricked devices (if the owner doesn't have own full backups).

If someone have bricked device with a sensitive "secret" partition data lost, he can look/ask for "secret" partitions backup images and other resources in the Russian 4PDA forums, but only for an MTS Smart Sprint 4G (there is no other clones in Russia AFAIK) and only (read/talk) in Russian (that's not my rules, sorry, use online translators. I think a small parts in English will be tolerated).

To all! Please always DO a FULL firmware backup using MTK SP Flash Tool (Read Back function).

There are many illustrated manuals around how to make it. You can back up the full flash (NOR/NAND/eMMC) contents in one image (including your unique set data NVRAM w/IMEI's, etc) either any part of flash including particular partitions and address ranges.

Also it always preferred to know the TestPoint location in your particular device, which will allow you to activate Mask ROM Reference PreLoader and repair (restore your backup) from any software failure ever (including flash-located PreLoader damage).

Read how to deal with your device's HW. Make full flash backups to be on the safe side in any situation (excluding HW damage).

If you can make and have a full backup for MTK, then you should not afraid of any SW failures anymore, including inappropriate FW flashing. You can try any FW's w/no fear. However, please avoid flashing too much times a big amounts of data (like a whole FW) to the internal flash media (being it NAND or eMMC), because you will wear it out too fast, just like you worn out a few cheap USB flash drives in a last few years, I'm sure. :)
