in some case you can contact your carrier and give them your imei # and the will give you the sim unlovk code. You can also buy an unlock code from ebay or other internet sites. Did you asked the persons who Jtag repaired your device if they can provide you this code?

SIM UNLOCK PIN seems to be a security code from the sim card, try with another SIM Card from same carrier. Apparently it has nothing to do with unlock code.

So I had SIM unlocked at&t htc one (I obtained unlock code from carrier). Once I unlocked it, i was using european simcard and then revone s-off came out. so I s-offed it successfully and after reboot i got exactly same problem - enter sim imsi unlock code or something like that. Any code would result in unlock successful and reboot phone, but it would ask code again. I ended up sending phone to HTC for repairs. I guess they completely reflashed firware or updated something else, since phone that i received back had different IMEI then what i send them (same physical device though - scratches on the side). I had to obtain new unlock code for new IMEI and new code unlocked it for european sim.

Dial prompt for sim unlock on ls991? (or another method?)

Hi everyone. Could someone please give me the dial prompt or another method to enter an unlock code? I bought an unlock code but can't find a way to enter it. I've also tried mayrer's method (here: http://forum.xda-developers.com/spr...sim-unlock-t3229801/post63465284#post63465284) to sim unlock without codes but it didn't work, unfortunately.
When I put an unrecognized sim into the phone, it tells me it's an "invalid sim" but it doesn't go to another screen to enter any codes as I've seen in some videos.
Any help would be appreciated!
Edit: I have the the ls991 zv5 5.1. Flashed to stock and rooted. Trying to get it to work on Orange network in Spain.

Hi,
Try these, maybe you can solve this issue:
Apply the Defreeze + Network Code if you still get the message “Unlock Unsuccessful”. It takes 5 steps:
1. Type your Defreeze code (or MCK): xxxxxxx and press Unlock button. You will get "unsuccessful” message again but don't worry.
2. Now type the Network code (or NCK): xxxxxxxxx and press Unlock button. If your phone shows “Unlock Successful" message, congratulations, your phone is unlocked. If not, proceed to step 3.
3. Make a hard-reset or factory reset of your phone. Please be informed that a hard-reset will restore your phone to the factory settings, so all apps, data and other settings added by you will be removed. We advise you to make a backup or save all data you want to keep.
In order to make a hard-reset you can either dial *27673855# on your phone or, if this method is not working, you can use these instructions in order to make the hard-reset.
4. After your phone restarts, type the Defreeze code (or MCK) xxxxxxxx, in the area below "SIM network unlock PIN" message or "Enter Network Lock Control Key" message. Press the unlock button. It will say "unsuccessful" again, don't worry!
5. Type the Network code (or NCK): xxxxxxxx and press Unlock button. Your phone should now give you the message "Unlock Successful".

Can't unlock bootloader

Recently I tried to debrand my P9 (EVA-AL10) with SRK-Tools, but something went wrong and my phone booted into E-Recovery. I tried to restore the phone via E-Recovery but during the download it gave an error and it won't let me download the firmware. So I downloaded the EVA-AL09 firmware from the internet and flashed it via dload. Everything went fine but when I tried to unlock the bootloader with dc-unlocker it only sayd unknown response. I tried to unlock the bootloader via the official emui site but it only sayd that the account has not been used more than 14 days on the phone. So I emailed Huawei support and they said I schoud send them my phone data. I did so but they only replied that my phone doesn't come from the state where I life in and they can't do anything. So im now stucked​ with a locked bootloader. Can I do anything? Like install an other firmware or unlock the bootloader in an other way ?

I also can't unlock my bootloader. When using the DC-unlocker to read the code, did you enter manufacture mode first? (Enable "manufacture mode" on your phone. This is done by entering in dial pad code *#*#2846579#*#*, select "Project Menu", "Background settings", "USB ports settings", "Manufacture mode". Then connect it to PC and install drivers)
I was able to get the code from Huawei, but when I try to enter fastboot command to unlock I get "Failed: password wrong"

I used the code from Huawei and it worked for me. On EVA-L09 though. Did you make sure you entered the details correctly to request the bootloader unlock code from huawei?

Strangely it wored now just fine with dc unlocker and I was able to root l.

I must have entered the information in 4 different times, both in English and Chinese site. I get the same code each time. I even rolled back to MM and requested. Same code each time. Not sure what else I could be doing wrong.
Edit/update: I tried to unlock with DC Unlocker and it worked. The code that DC Unlocker gave me was different from the official Huawei site.

Rebranded CLT-L29 Upgrade to EMUI 9 and no service - Emergency calls only.

Hi,
So a while back I rebranded my CLT-L09 to CLT-L29 C432 which went fine. Even though I have a dual sim tray it doesn't recognise the second sim, so I just left it as is as I was hoping that at some point in the future a tool would be released to convert to dual sim.
Yesterday I upgraded to 9 and the first sim which was working, now does not work. I don't get the prompt to enter the PIN and the phone just says emergency calls only. I tried reverting back to 8 and the sim is recognised again.
Would quite like to go to 9, so what are my options? Can I use the same rebrand files and oeminfo to rebrand to CLT-L09 C432 for example?
Thanks,

Ok - so the SIM had a PIN on it. Removed the PIN and it's now working - so perhaps there is a bug in 9 with the SIM PIN prompt which never gets shown to unlock the SIM?
