Unfortunately we do not have NXT-L29 version factory firmware nor it could be found in Huawei, so your best chance is to revive it with same model, different version factory firmware, then try to update via upgrade mode/sd card with stock NXT-L29 firmware.

@Valdemaras

Do not use test points, use method 2 from dc phoenix guide. Without trying you won't know if possible as we can nopt confirm such thing when different phone version is being updated with factory firmware from another.
