my lenovo vibe b A2016a40 experience

hey guys!

i had the stock version S235 for the lenovo vibe b a2016a40, unlocked the bootloader, flashed recovery with version twrp-3-1-0-0-al732row-unofficial.img and installed supersu.

i also upgraded to stock version s238 later. and managed it to get root. all working for me.

then i tried a few custom roms, such as:

lineage 13.1 al732row version

lineage 14.1 al732row versions from carlos and from eduardo (i tried a few different uploads from him as well from may, from sept 2017) so i tested 3 versions of the 14.1

resurrectionremix version RR-N-v5.8.4-20170916-al732row-Unofficial from eduardo

viperos al732row-7.1.2-Python-v2.1 versions 20170912 and 20170916 from eduardo

(all without gapps installed/flashed)

all mentioned systems seemed to work okay. could boot them, could "use" them.

lineage13 version has the wellknown camera bug, etc etc.

the other minor bugs are fixable. with some research. e.g. in viperos or resurrectionremix versions the camera is working. the soundbug in resurreciontremix is fixable with some data; and other stuff too. the only thing i recognized was the flashlight working only a few secs, then turning off for no reason.

...

but all of the versions had one BAD THING in common: i got "no service", no sim cards detected, no imeis, etc.

so i could use the device as a little computer, connecting it to wifi and play around with apps and other functions. but i couldn't use the device as phone ... couldnt fix this.

not with other programs, such as aroma efs backup, chamelephon app, efs-imei-backup app, andromizer app, rommanager, mobileuncletoolbox app, and a few more. so i tried a few things to back up some parts of the system to save the imei and other infos needed but it didn't work out. also not with extern progs or some kind off dd if= of= things etc.

so, what steve 8x8 says about the the baseband and sim issues in post #31 could be true or was tested with this. what do you think?

with stock version, "adb shell getprop | grep -i ds" returned:

[gsm.project.baseband]: [HQ6735_65T_B1A_M_HW(LWG_DSDS)]

[gsm.project.baseband.2]: [HQ6735_65T_B1A_M_HW(LWG_DSDS)]

[persist.radio.multisim.config]: [dsds]

[ro.lenovo.lcdsize]: [4.5]

[ro.lenovo.sim]: [dsds]

[ro.product.ota.model]: [Lenovo A2016a40 ROW DS]

after flashing rom(s), the command returned only:

[persist.radio.multisim.config]: [dsds]

has anyone a clue or a solution, how to fix this specific problem?

p.s. i could fix this "bricked phone" with spflash tool and a stock recovery img. so its working again and the sim cards are working with the stock os.

btw: for a Stock os rom or as you may call it --- just type "Lenovo A2016a40 stock firmware" in your searchengine. that should provide you with a link to the file.

p.p.s. is there any rom out there for the lenovo vibe b A2016a40? e.g. some old cyanogenmod version or sth else that is working, tested? for me it would be ok if the version is a bit outdated. as long as i got a "clean" system, that i can customize and that i can use as a phone :)

p.p.p.s. anybody out there who tried the ubuntu touch os ? perhaps this could be a solution for the lenovo vibe b ... ???
