[Q] [SOLVED] How to enable diag mode on SGS4 without code - Galaxy S 4 Q&A, Help & Troubleshooting

Hi guys,
I have a samsung galaxy s4 with no imei label on the battery place and the screen is smashed so no way to activate the debug mode or the diag mode
The only thing I did so far to be able to read the IMEI is to boot the phone in Download mode but CDMA tools are not working as the phone is not in diag mode.
Anybody knows how can I read the IMEI of this phone? I checked this post but even getting into ADB it´s complicated as it never boots on the Recovery mode.
Thanks in advance.

Ok, I think I know now the answer for this just in case somebody will have the same issue...
As I don't have any option to control the phone as the screen is smashed, there is no way to activate the Diag Mode (*#0808#) in order to make the CDMA tool read my IMEI.
Solution: I found on Ebay an HDMI adapter with also USB host for 10 british pounds approx. This way I should be able to use my TV as the screen with a mouse or keyboard
It's on its way, so as soon as I get it working or not I will post how it goes.
Cheers,

Solved.
With the device I mentioned I was able to connect the phone to the TV via HDMI and also adapt a USB keyboard to be able to control it as the screen was broken.
Happy days!

[Q] I9000 boot problem

Hello,
I have problem with my SGS I9000. When I am trying to turn on my phone, I can see only SAMSUNG boot screen blinking again and again. I am NOT able to run recovery mode or download mode (it's strange for me). And what is strange, when phone is turned off and I will plug in battery charger, there is only "spinning" circle.
I know there are threads regarding this problem but other users were able to run download mode, but I am NOT :-(
Thanks to everyone for any answers.

Have you been able to get into download mode previously? If not it's probably not enabled.
The best approach is probably to make/buy a USB jig. Check ebay.
I was able to run download mode before. Yes, thank you, I already found out how to create jig and I made it.
So pls close this post and sorry.

[Q] Us cellular s4 Diag Mode

I am going nuts trying to figure this out. I got my phone into DM mode and was able to connect DFS and CDMA WS to it and then all of a sudden it no longer is able to be read. I have done just about everything I can think of to get it working including a rtn reset and clearing efs on the phone. Nothing seems to want to kick it back into a usable DM mode.....
Anyone care to help me??

can you share how you got it to connect diag mode in first place. i have been struggling to do that. usb debugging is on, hidden menu screen enabled but doesnt show qualcomm settings in the *#7284 screen. I did try *#0808# and it shows the qualcomm settings there however it doesnt connect to computer when changed to dm mode. thanks

*#7284# click modem i believe (you might have to toggle to pda later)
After you do that part this is what you do.
As long as the hidden menu is enabled
press *#0808#
this will bring up a menu kinda like the s3. Under usb settings change it to
dm+modem+adb
you'll get 2 serial and modem ports. Toggle the pda and modem back and forth and it should read. *now just need someone to find the 16 digit passcode and we're all in there!
Hope this helps!

Bricked A2017G B03 - help please

Hello!
As title says i bricked my Axon :crying:
I followed http://forum.xda-developers.com/showpost.php?p=68738854&postcount=100 (and the german one that linked to this one) but couldnt do the fastboot unlock.
So i couldnt finish this and my phone required a pin number to start android: bootet and started up but wanted a pin code to start/enter system.
Wasnt able to fix that with googling for answers so i went back to edl mode and rewrote my backup boot/recovery images with axon7backup.
Had no errors with that but it wont start now:
After the ZTE Logo the display goes black but it connects as "handset diagnostic interface (DFU) (ComX)" to my computer.
I fiddled around with driver installing etc and forced the HS-USB QDLoader 9008 on it but no luck, axon7backup/root can not connect.
When i did the actual flashing yesterday it never connected with the hold both vol-keys and connect usb way either, always had to reboot into edl via adb.
I cant boot anything else (no twrp/recovery) it just goes to the diagnostic interface mode.
Thanks in advance
you can try to get into adb mode with this:
- power off your device
- hold the vol down key while plugin in the usb-c cable (connected to your pc)
- keep holding
- you should get a white box with FTM factory test mode
- you are free to use adb again - so you can get into edl mode as well....
for pin part that'S normal while unlocking your device encryption gets deleted and you have to abort and factory reset your device in twrp....

Thanks. I tried it but it wont go to FTM. Only goes to diagnostic com port.
It seems i cant even turn it off. The little red light on the front is on the whole time .
sadly the disadvantage of a built in battery, so you have to wait till the battery is empty and try my instructions then....if it's not realy off it won't work, the mode you are currently in you usually only reach if you switch it on while holding both volume buttons, the edl mode is sadly not reachable with a key combination directly on G models.
adb don't show your device?

Oh ok. I expected ftm to work from vol-down and power-button till restart.
@adb: sadly no connection possible since it goes straight to Comport Connection.
Edit:
Couldnt make that work. It was off and i connected the usb. So it showed me the loading battery picture where i cant do anything. held the vol-down the whole time. But as soon as it had some battery it went straight to comport-connection again
im sorry to say, but ur device is bricked to a degree where you would need ZTEs Flashtool to fix it. Unfortunately we dont have that tool, so you might have to send it in
i have the same exact problem :'(
Have u been able to fix it?? I'm in a situation that i cant even send it to ZTE to fix it :'(

Hi,
couldnt fix it myself so i had to send it in.
Unless some tool/rom was released in the last few months to fix it yourself i would guess your device is bricked.
Hi I have almost the same problem, I tried to unlock bootloader and now I don't have the recovery, I can boot and use my mobile but I can't restore it or update it because I don't have the recovery
I try whit axon7tool to restore the recovery but I got a error.

Hi, do you have any idea, if there will be such a flashtool to work with DFU mode? I'm thinking that there are a lot of guys have bricked their devices (including me).

Enable debug mode on a LG Leon LTE with broken screen

Hi guys,
I have the phone of my father in law that (I think) is a LG LTD Leon that have a broken screen which stays black when I turn on the phone.
I would like to be able to get back all the datas, like the messages etc to put them back in his new phone (a Galaxy A5) using Wondershare MobileTrans, the thing is I can't enter the pincode on the LG nor activate the debug mode for MobileTrans to work.
I read here and there (on androidphonesoft and fonepaw for instance) that you can enable the debug mode of a phone with a broken screen using ADB commands but I don't know how, so is there anyone that could help ?
Also will the ADB commands help me enter the pin code ?
Thank you in advance for your help.
Ugo.

HELP! SG S4 i9505! Broken and Black Screen. Help on Enable USB Debugging! Please!

first of all, i'm sorry if i'm posting this o the wrong section (i'm new here seeking help)
second, I NEED HELP!
i tried using Dr. Fone for recovery and unlock but i'm getting "flash recovery packaged failed" on the end. when on recovery device mode, i can hear the new device/unplugged sound.
if only i can use OTG and mouse to enable USB debugging. but obviously i cant see. when i open the phone normally and try using screenshot, i can hear the sound. so that means that my phone is not dead and only have broken lcd/screen. i also cant open the device folder because its locked (i think its locked). i also looked some class a ldc/screen digitizer but its kinda expensive and going to technician doubles the cost. from this point, i don't know what to do anymore. i just want to get important pictures and video. been trying to find a solution for hours.
I have not seen a method to enable USB debugging without a working screen.
