unknown baseband and imei null/null

This means phone's modem part is damaged in your phone. This can be Software (modem firmware is damaged or You have written unsuitable firmware) or HW problem.

Try to re-flash the device with different firmwares and check, whether modem (baseband) is correct (not Unknown).

If after writing all firmwares, which You have, phone's baseband is still Unknown - most likely, this is HW problem (problem with phone's eMMC flash chip).

is it possible to read modem firmware from working m919 and write on it?
If so what would be the procedure thanks

Octopus box · 06-20-2014, 11:23

You can try to write modem firmware "SGH-M919_modem_CWM_UVUAMDL" from the Support Area or You can try to read and write via Jtag tool.

caitontx · 09-23-2014, 20:06

I have the same issue. this happened after I tried repairing imei. when software asked to connect to box via uart cable. it never found phone and resulted in bad baseband and imei

Octopus box · 09-24-2014, 06:37

Please poshere full Software log with that Repair IMEI procedure. Also now You need to re-flash the phone to repair baseband.

ronsten56 · 10-17-2014, 21:49

hello. new with octoplus. i was doing imei repair on sgh m919 4.3. i rooted the phone manually. the usb part seemed to work fine. it made backup and said to remove usb. wait 1-2 mins and connect to box with uart. when connected it just says searching for phone forever. never finds phone or gives error, it just sits there. i was able to repair sgh t999 today with no problems but all was done on usb...no uart cables. i received a giant bag of cables with my box. i tried every one that can connect to the m919. most there was no response at all. with the cable labelled rx-at170 muai, the phone did beep and respond but still not recognized by box. do i need to be using a specific cable? is this something other then the cable? any help is greatly appreciated. thanks

ronsten56 · 10-18-2014, 00:33

i was thinking this could possibly be my problem. when i pull up the diag menu it says set to usb value. there are several options, two of which have the word usb in them. which option should i select. thanks

11. Enter "*#9090#" number.
12. Set "Diag config" to "USB" value.
13. Restart phone.
14. Press "Read Info" in software

Octopus box · 10-18-2014, 07:42

Hello.

Please post here full Software log (or, if You can't post it here, send us to PM, we will check) with all of your actions. Also, You can contact us to Skype, Yahoo! Messenger or ICQ, we will look remotely, where can be the problem and will try to help You. Our contacts You can find in our profile.

ronsten56 · 10-21-2014, 22:48

i sent the software log to you in a private message. not sure if it went through. can you please confirm you have received. thanks

Octopus box · 10-22-2014, 06:40

Try to do the next:

1. Install the latest Software version (Software).
2. Make Repair EFS.
3. Re-flash the phone.
4. Make Factory data reset and wipe cache partition.
5. Make Repair IMEI.
6. Write this QCN file (https://mega.co.nz/#!Tsgg1TZC!n6X6Bj...nB-yHpxiMBnkvM).
7. On the second step of Repair IMEI procedure, connect the phone to Box via Samsung Micro UART C3300k/C3303k cable. Try to use another Samsung Micro UART C3300k/C3303k cable, maybe the problem is with cable.
8. Post here or send us to PM full Software log with all of these actions and say the result.

ronsten56 · 10-22-2014, 22:07

not sure how to do step 6. how do i write qcn file. i have to ask. did you see anything in the software log? you recommend that i do all those steps, but then say if they dont work it may be the cable? is there no way to know? i have looked everywhere in the forums and seen many people with the same problem, but not any real solutions. seems like uart is problematic.

thanks

ronsten56 · 10-22-2014, 22:31

not sure if this could be the problem, but need to ask either way. when i do the *#9090#, it says set to a usb value. i am not sure which option to select. could this cause a problem with uart connection? i have been able to read info from the phone and it connects fine with usb, just not uart. thanks

Octopus box · 10-23-2014, 06:49

Try to use another Samsung Micro UART C3300k/C3303k cable, maybe the problem is with cable. Also, You can try to use another Box as UART inteface, maybe the problem is with Box COM port. Also prefrom all steps 1-7 and post here full Software log.
