Asha repair advice when imersed( not powering)?

Evans phiri, you will have to approach this like any other device that has been immersed. First thing you want to do is to stop trying to charge it, sync it or trying to turn it on. Remove the battery do not reuse it at all, and disassemble your phone. Clean every part, including the connectors on the board as well as on the cabled with 90%+ isopropyl alcohol and a soft brush. Use this guide to show you how to clean it. It was written for an iPhone but all the steps are still pertinent to your phone. Be diligent about it and clean it well. This does not mean to scrub hard, just rinse it in alcohol often. Check for any burned looking or missing components. After that replace the battery (not an option but a must), reassemble it and re-evaluate. Water damage is the hardest to trouble shoot and the hardest to repair. Even with all those steps, chance are slim to get it done, but the longer you wait the smaller your chances. Hope this helps, good luck.
