[Samsung Galaxy S7 Edge Questions and Answers] Citdo3:
I flashed the combination of binary U2 to restore my i Mei and drk error but it shows modem crash in the binary mode and cp crash mode.

I hope someone can give me a solution that's useful and it's okay for me to pay by PayPal after it has been fixed.

The following is the message I sent to cubz but he doesn't seem to be free to active these days so I hope anyone else can help me.

{{{{Hi, I've seen many posts in the xda and many people refer the solutions and fix advice to your name on comment so I think you will be the only one who can help with my issue.

Firstly, I had my S7 edge flashed with many roms before and flashed with odin ( with sim card always, not knowing if this is a major problem), but after once I did after using the encryption on the S7 edge with the lineage OS ( the 8.1.0 one in Feburary), I tried to flash with other rom without decrypted it and flashed fail. ( roms are all android 7.0 and 7.1.2)

Since then, I tried to flash other rom (7.0 like superman rom or rom from SAC) but still losing cellunar signal. then I tried to flash the original android 6.0 official firmware through odin but it failed on the step which shows DRK error on the samsung official 6.0 recovery.

After reading your post on how to fix DRK error, I tried the method but maybe because of I don't really know the steps or how to restore on the binary factory firmware, it boots up but still lose of IMEI and cellunar signal.

After the android 8.0 is released officially, I flashed the official rom and I tried using the U2 version of bootloader binary factory which you shared, but same problem happens and I also tried the V5.7 devbase rom and same.

Very seldomly the baseband and imei will show as normal and having cellunar signal but not long and after I reboot will gone to unkonwn to the imei and baseband and show as 'no sim card'. ( there was one time that I ticked clear efs on odin then i lost the imei. But after i flashed the binary firmware, imei show unknown in the binary firmware mode but when i flashed back the devbase rom with twrp, the situation of mostly showing unkonwn of baseband and imei happens but very seldomly it will load as normal which they are shown correctly)

*Btw the first flash the U2 binary firmware( Im using the U2 version because my bootloader has been updated to the oreo one), it boots into the screen that shows cp upload or modem upload error? page , then i flash again but with efs clear which was what happened as I mentioned before. ( thats the only time I ticked EFS clear as i can remember)

Dear CuBz90:

I really hope that my s7 edge can be fixed because I have had it for more than two years already and it was the first time that i buy a phone using my own my money but not my parents, I hope you can help me with this issue.

Thank you very much!!!

( its okay if I have to pay( its okay through paypal) after its fixed, but hopefully not too much)}}}}
