      With full access mode only some parameters can be changed with this software. If you need more options, you need to use bq studio or other professional tools, but those only support ev2300 or ev2400. So if you want to change only cells, , do recell and dumb and upload eeprom, it will clear errors and do cycle count change and full charge capacity. Other parameters can't be simply changed, it needs more information and knowledge.

    Hello Sir, it just seems that the writes are accepted at 00 register but the chip wont unseal, further write commands are accepted but changes are not made, tried both keys but none has effect on unsealing this BQ4050 gauge ic, the pack was made by samsung, i think it should have different keys, where can i extract them? i cannot understand the proccedure in the TRM manual. i will try with CP2112 method and later with the aliexpress knockoff of the EV2400 to check if i have luck

      First try all common keys available on the internet. And there is no universal way to enter boot mode. Free tools are not offering easy unlock. Because nobody knows the correct way of unlocking. So at this point we need to use other paid software which supports the unlocking of your chip.

      reading the TRM for the BQ4050 they explain that all keys are presented in the memory but not in plain sight... if this whole thing was actually not that difficult at this point... try with cp2112 method which uses other software. if no luck go to the aliexpress knockoffs of the EV2400 which can use the official software BQStudio from texas instruments...
