LEMFO LEM P 4gb + 64gb (Prime style watch) support thread

Hi, I have a Lemfo lemp and I really love this watch.

The battery uses to last from one to one and a half day when you use the watch connected to wifi AND/OR with 3G mode.
Not 4G. 3G.
If you enable 4G, the battery will last from 3 to 5 hours, on this and every 4G capable watch. 4G always uses more power.

Since at the end of the day is just a smartwatch (not a smartphone) I always let it connected by 3G when I’m not connected via WiFi. I receive all notifications and I even can use Google maps or GPS by using 3G, so it’s not really a problem to me and the battery saving it’s a gift.

Hey @stingray22 how do you enable 4G vs 3G? There’s a mode switch between 4G and sport, the latter supposedly saves battery, however @pablo11 in another thread explained that those are essentially are running the same OS, just with a different launcher (if I understood correctly).

Thanks for the advice, I won’t pursue firmware for now, I’m still just exploring the watch. When I check for updates the OS (LEMFO boot logo Android 9.1) tells me that I’m up to date. I read some topics how the hardware shifted from MTK to Unisoc. I have some rooting experience with Android phones, but I don’t consider myself a root or AOSP afficionado.

You need to go to Settings and network to change the cellular settings.
4G uses more power if the ISP provider does not allow access to their LTE network.
If you can connect as LTE it will use less power.

Go to settings → internet & network → mobile networks → advanced → preferred network → 3g/2g auto.
That’s all.

Hi all! Is it possible to patch boot image of this device and flash it in SP Flash tool to gain root access?

195

I wouldn’t take the risk…

196

So no one tried that before? Is it technically possible at all? I can get the device very cheap and I have another watch so I’m not too afraid

197

I don’t think it will work. But why not try it? It’s only a LEM P, after all.

yea, I think I’ll try when I get it in my hands :grinning_face_with_smiling_eyes: Do you possibly know where I can download the latest firmware/ROM for this watch? 4/64 variant

Using sp flash tool which is for MTK on an sprd chipset = bricked watch as far as I know.

It would be easier to OEM unlock the preloader if possible and then use fastboot commands.

My advice is to visit Hovatek and read what others have done. Above all, research as much as possible or you will have problems.

I can see what firmware is available

yes, thanks for the advice, I’ve been reading meanwhile and I know I’d have to use SPD Upgrade Tool instead. I’ll take a look on Hovatek forum as well.

Interesting case, I have quite a lot of experience with unlocking and rooting Android devices, but have never encountered this processor. A new challenge :smirking_face:

I’ll be greatful for latest firmware :blush:

meantime I found a guide on Hovatek regarding rooting Unisoc Android 9+: How to root Unisoc | Spreadtrum Android 9+; Case study: Teclast P80X
Perhaps it’s suitable for LemP as well… :thinking:

EDIT: And Auto TWRP porter :hushed_face: Auto TWRP porter; MTK v1.6 & Unisoc (SPD) v1.4 – Hovatek Blog

I won’t get the device until the end of the next week and at Saturday I’m going for a short vacation so presumably I’ll be able to perform some test later only. Until then I hope @pablo11 be able to find the latest available firmware. If I manage to get root, I’ll definitely let you know :slightly_smiling_face:
