U696CL Old Thread - Android won't show up as USB device on VirtualBox after putting phone in ADB/EDL mode?

Your TWRP recovery is brain-dead. I've tried to fix it. Give this a shot.

Your TWRP recovery is brain-dead. I've tried to fix it. Give this a shot.

I ran "fastboot flash recovery C:\Users\user\Desktop\fixtwrp.img" but it just has main stock recovery with the green robot, red warning icon, and "no command."

 

[Renate]

Yeah, I missed something there. I was just going to tell you not to bother.
You mean like the bootloader screen, right, not really a recovery screen? It doesn't say Recovery 123.456?

The original recoverytest.img is totally half-baked. It's missing init. I wasn't quite sure if there was a copy in system or what was happening.
I put in all the symlinks that were in the stock recovery.

What's your complaint with the stock recovery? That it doesn't have ADB? We can fix that easier than beating our heads against the TWRP.

I can access adb. I just want to put TWRP on it and figure out why non-stock keeps being overwritten. Currently cannot get the super.img extracted at all with anything. Using dynamic but not A/B.

 

[Renate]

I can access adb.

Yes, I know that you have ADB when the regular system is booted. But does the stock recovery give you that? What is it about TWRP that you want/need?

Me, I just need rooted ADB in recovery. If I have that, I don't need anything more. I can do my updates or whatever.

You really need to hook up a console UART so that you can see what you're doing. Without that you're flying blind.

 

[aIecxs]

so go to the contact form and ask for firmware

I actually did that this morning, haha

you could also request user release source code in compliance to GPL. You can probably pick up in person between 9-5 in Shenzhen office

I guess you need source code for building TWRP yourself. any response here?

 

[Renate]

As I said, there's a bunch of stuff that I've never run into before, the Android Type 2, dynamic partitions. That's one of the reasons I like mixing it up with stuff like this; I might learn something.

The TWRP that you're using is missing init, linker, sh, recovery, basically everything needed to be functional.
Edit: Oh, @PizzaG I hadn't realized that this was your build.

I know this phone is MSM8937...

The EDL HWID tells us that this is a "QM215". Despite hints otherwise, it is no MSM8937.
I learned something here too. I never knew about multiple DTBs in one file.
The stock system, recovery and the TWRP all have DTBs for 8 models! What wackiness.
And the silly things are unaligned even. Sheesh, there was a patch for that in 2016.

Qualcomm Technologies, Inc. MSM8953 + PMI632 SOC
Qualcomm Technologies, Inc. MSM8953 + PMI632 SOC
Qualcomm Technologies, Inc. QCM2150
Qualcomm Technologies, Inc. QM215
Qualcomm Technologies, Inc. SDA429 CDP
Qualcomm Technologies, Inc. SDA439
Qualcomm Technologies, Inc. SDM429 MTP
Qualcomm Technologies, Inc. SDM439 MTP

Not that it's that big a deal, but you could cut down the size of the DTB from 2,235,141 bytes to 222,705 bytes.

Edit: The screen resolution is 480 x 960? That's incredibly cheesy. My $35 phone is 720 x 1440.

Well, here's a shot in the dark, a proof of concept (or not). It's a custom recovery.
If it works you should get a white screen, hopefully with text, but I'll accept diagonal whizzes.
If you are lucky you might have ADB on 18d1/4ee7

You can try it fastboot boot or fastboot flash.

Will this allow TWRP? I'm not sure what "18d1/4ee7" is or means.
Regardless, it seems when I hold power+volume up to enter recovery, I just get a blank black screen.

 

[Renate]

Well, do you get ADB? Does it bong when you connect/disconnect.
No, this is not TWRP.

No.

 

[Renate]

Oh, well, try this.

 

[gregeerg]

Oh, well, try this.

Nope. Just sits on UMX boot logo screen for a bit then keeps resetting. No ADB.

 

[Renate]

This stuff is too tough tedious to do by remote control without even an operating console.

Sure is, haha.
Any idea why my phone keeps rebooting and then going into recovery?
All I did was have LineageOS19 on it and set up, then I went to recovery and wiped phone, then flashed LOS18 back on it as well as stock recovery.img to be safe, and now I can't get it to boot into LOS18. Just UMX boot logo then resets then goes into recovery green robot logo screen.

 

[Renate]

C:\>fastboot erase misc

 

[gregeerg]

C:\>fastboot erase misc

The fix was re-flashing super.img (thank you, PizzaG).
fastboot flash super super.img

Sent you the files that we pulled.

sorry but the files pulled are just garbage. you probably did from windows, right? please remember exec-out is only working from linux. I did not find a way to pull files from windows, yet. please upload to mediafire it's free. also please provide checksums

phhgsi_a64_ab:/ # sha256sum /dev/block/*/*/*/by-name/*

I did it from Linux

 

[aIecxs]

then adb exec-out is probably not working in general. do you have access to MicroSD Card meanwhile?

then create some directory on it and make dumps in there (where 0815-4711 is the UUID of my SD Card, yours is different!)

phhgsi_a64_ab:/ # cd /storage/????-????
phhgsi_a64_ab:/storage/0815-4711 # mkdir u696cl
phhgsi_a64_ab:/storage/0815-4711 # cd u696cl
phhgsi_a64_ab:/storage/0815-4711/u696cl # for b in $(ls /dev/block/*/*/*/by-name/!(userdata)); do dd if=$b of=${b##*/}; done
phhgsi_a64_ab:/storage/0815-4711/u696cl # sha256sum /dev/block/*/*/*/by-name/* | tee sha2.txt
