Tecno Pouvoir 3 LB7 says Unknown Bootloader
(14-10-2021, 02:53 AM)Ogwuche I formatted whole ROM and flashed my LB7 with a stock rom on SP Flash Tool, little did I know I was never to do that. now the phone says unknown bootloader, IMEI NOs gone, and phone doesn't respond to engineering mode code.
(14-10-2021, 02:53 AM)Ogwuche Luckily, someone wrote the IMEI code back, but the other issues persist. other apps say the device is not an MTK chipset.
(14-10-2021, 02:53 AM)Ogwuche ...and still I got this error: invalid preloader format.
(14-10-2021, 02:53 AM)Ogwuche I also tried to flash NVRAM.bin into the phone from the stock room I got, but it failed. the rom did not contain NVRAM.data. is there any solution to this challenge???

you probably used the format option in sp flash tool

not sure what apps you used but cpu-z or droid hw info should give you the correct chipset

stock / factory rom never contains nvram, you can either backup nvram from a working phone or try writing imei, mac addr using modem meta or aftersales imei tool ; see https://www.hovatek.com/forum/thread-116.html

However, using Droid HW Info, it says Unknown preloader. Is this an Issue?
(15-10-2021, 09:53 PM)Ogwuche Secondly, when I dial *#*#3646633#*#* I get a blank page. This situation applies to other GSM codes aside from *#06# which displays my IMEI numbers. Is there a way to fix this?
(15-10-2021, 09:53 PM)Ogwuche Lastly, when I used MTK Engineering mode and MTK Engineering mode apps from play store, CDS INFORMATION option is missing.
(15-10-2021, 09:53 PM)Ogwuche When I click on the android settings MTK, it tells me it cannot find the engineering mode app. Although none of these issues appear to negatively affect the phone's functionality, I am curious to know if there is a way to fix it?
Quote:i think you mean "bootloader" not preloader, either way it's not an issue
Quote:this ussd code doesn't work on all mediatek devices, if you're trying to get to mtk engineering mode then you should use the "mtk engineering mode" app from playstore
also note that engineering mode isn't available to all mediatek devices either
it all comes down to what featues the OEM implements on the device or not e.g in most nokia mtk phones if not all, they removed mtk engineering mode completely
Quote:No way to fix it, it's not a bug rather that's how the oem made their devices, to come preinstalled without the feature
