C103 Easy All in One Discussion Thread

Hi everyone, I'm using Coolpad Cool 1 C103 and through fire and hell in the early days, managed to get my device bricked, IMEI lost and then thrown into the dustbin just 3 days after buying it.

After a week of meditation, I decided to try to revive it and managed to get TWRP installed and the rest is history. So, in order to help the newcomer, I've decided to create a thread to help with the device. My device is C103, so my reviews and guides here are compilation of what I've done. Other member with different experience and method can feel free to share it.

Custom ROM Bugs :

Android 8.xx
LOS 15.1 by @SimbyOS
- everything works except that it's hard to lock into 3G signal. I can't get H+ signal.
- i can't switch between Wifi and Wifi Hotspot tethering without rebooting.
- no stock JUI camera, so Monochrome lens is unusable.

JUI 8.0 by @SimbyOS
- no Monochrome lens in stock camera
- wifi hotspot tethering doesn't work
- video recording works
- Magisk root and modules working well

Android 7.xx

JUI by @Cuoco92
- unable to record video and voice record
- ROM is rooted with Magisk but most modules don't work such as Youtube Vanced and Viper4FX
- device sometimes freeze and goes into non-stop vibrate.
- need daily reboot for ROM to be running smoothly.
- mic doesn't work in calls

JUI Cool Play 6 by @Machomotofan
- wifi doesn't work on my C103 but you can flash wifi driver.
- stock camera all working well including video record but no Monochrome lens option
- Bootanimation is in Russian

JUI Cool Play 6 by siv_88
- most stable JUI 7.xx for C103 for me
- prerooted with Superuser so you need to flash stock JUI boot.img and then root again with Magisk
- need to flash remove encryption after Magisk root .
- Magisk is stuck on Core Only mode so modules doesn't work.
- no sound and mic when calling. Fix in buildprop fixed it for me.
- stock camera doesn't work with gallery but i fixed it by flashing another JUI stock camera

I think JUI Cool Play 6 by @Machomotofan is really good the wifi worked at least for me...but IR blaster does not work in any of the JUI 7.0...And no monochrome lens...so had to revert to eui 18s

Help Please.How do i unlock bootloader?fastboot won't work ...remote failed error

 

[mamarama9904]

I cannot build any roms because of device tree bugs. there is a bug when merging kernel or vendor source.

you need to install all the corrent drivers. this device need a lot of digging and i've forgot most of the stuff and deleted the downloads since i've set my work station with all necessary esentials. but i remembered finding most of them in 4pda. you have to install coolpad download manager first to get the fastboot driver. and it's a pain in the ass when you're using win10. also you need to set you driver signature verification off and put your windows in test mode. yes, it's a hassle. go down this path if you're willing to tolerate and finding ways to repeteadly bricking and unbricking your phone. lol. and 1 more thing, update your phone to official JUI 1st and install Cuoco JUI to get the device ready with easy setup. Cuoco JUI comes with preloaded TWRP and Magisk.

maybe the source code has been offline. it used to get taken down before and then online again. maybe it's been taken down, AGAIN.

thanks to Droid Insight, I succeeded in building Superior OS for Cool1.
but I have not flash TWRP because of unknown error with QFIL.
so I didn't test this ROM and feel free to try this but all features are not checked.
It seems that there are same bugs with
https://forum.xda-developers.com/cool1/development/rom-t3948184
because I used same sources.

Have you flashed TWRP? Trying MiFlash might work for you then. Here, I've made a complete guide on how to goes to Android 9 from EUI/JUI. https://forum.xda-developers.com/co...upgrade-to-t3954064/post80007403#post80007403
