Hi,
My friends Samsung nexus s is stuck on the X screen. since the phone is on stock rom and no recovery installed and he doesnt want to root his phone and wants all his previous data back, what should i do to get back in orignal state without loosing data?
Well, if you unlock the booloader, then his data is gonna be lost anyways because unlocking the bootloader will factory reset the phone. The only way to get his phone working again is to unlock bootloader, and flash the firmware images, or a custom rom through recovery. Your friend is going to have to accept the change on his phone and data lost. Sorry, but I can't think of no other way to restore it WITHOUT losing data.
Hi guys need some help! :'(
I bought a N920-T from shop which was Unlocked and Working for other carriers on Kit Kat rom.
I then installed stock Marshmallow using Odin/Rooted and TWRPD it. And it was fully working with my international SIM. I made a backup of my fully working unlocked Marshmallow with all the items checked (EFS and MODEM too).
Today, somehow my rom got stuck and crashed and I decided to Restore it using backup which I made. Restore got through and everything was back EXCEPT I see "Network Lock:" screen on first time boot up after restoring it.
"The device can be remotely unlocked if eligible. Please use "Device Unlock" application to unlock the device."
Please help! What should I do? Should I launch the T mobile device unlock application and continue it with wifi and see what happens?. Or what?. My device was unlocked and fully working on Kit Kat and Marshmallow too. It means it was officially unlocked right?. PLEASE GUIDE.

It would not hurt anything or make things worst for you if you tried the Tmobile Device Unlock,
it will either network unlock your phone or it won't.
I used Device Unlock on my Tmobile Note 4 and my Tmobile S6 Edge+ and in both cases it
worked fine and unlocked my phones.
Good luck,
Have a great day!

First off the phone shipped with Lollipop not kit Kat. Second a true Sim carrier unlock is permanent and can't be undone as far as I know.
I do remember when you use the device unlock app their is an option to temporarily unlock, I wonder if that's what you had?

Unlocking the carrier lock is permanent
No amount of modding would change it
See if your phone is eligible to unlock: Mobile Wireless Device Unlocking.
From that Application list, tap Device Unlock.
Tap Continue.
Wait while the device connects to the server.
Choose the desired device unlock type:
Permanent Unlock: Permanently unlocks the device.
Temporary Unlock: Temporarily unlocks device for 30 days.
Note: Temporary unlocks must be performed with a mobile data connection. Wi-Fi will not work.
Wait while the device requests the unlock.
If successful, restart the device to apply the settings

I can't even use smart switch to go back to stock
The T-Mobile app didn't work. Permanent and Temporary Unlock said my device is "not eligible". I am confused, when I bought the phone it was working with other Sim and was on Lollipop/Rooted and then I installed Marshmallow T-Mobile Stock Rom via Odin/Rooted and it was still Unlocked then back up which I created was with EFS and MODEM checked in TWRP of Marshmallow. I think the EFS and MODEM option in backup creation and restoring it messed my phone up. But I am still wondering how was it unlocked?. T-Mobile says my mobile is ineligible, maybe shop owner used Z3X Box Samsung Tool Pro or something?
UPDATE:
I decided to use unlock services online. The one I used was unlockbase they have a software that unlocks the phone on-the-go and it requires internet connection. I got my phone unlocked and international SIM working. The question is that if I backup my EFS and MODEM now using TWRP and later restore it will it break the UNLOCK?.They guarantee that their unlock is permanent and modding won't do anything.
Because the unlock they do is of course by altering the EFS/FILES and in that case backing up EFS and MODEM is a safe way to UNLOCK my phone again in future if it somehow gets LOCK again, right?.
For Developers: I have my before/after EFS files backups. Before unlock and after unlock, if some developer wants it for research purposes, I can send it to you for the sake of development.

ask the gentleman to unlock it on xda he's awesome! Never restore it'll cause you to loose unlock under all cercumstances I've learned not a big deal
UPDATE:
I have Saved my UNLOCKED EFS and Modem Files, and upon restoring those using TWRP my phone gets unlocked, tried purposely after locking my device and it works, you just gotta save them EFS Files (unlocking services like via box or online tools edit these files in order to unlock) , they are the real deal lol. Made Several copies of my Unlocked EFS/Modem Files xD
Hello everyone,
I recently got an htc u11, my first android phone, to kind of play around with and see what I could do. I was messing around with rooting it and unlocking the bootloader etc. Then I started to play around with the firmware. Basically I got the sunshine app and flashed some firmware and now when ever it boots up it says the phone is encrypted and that if you enter the wrong password it will reset all the user data. After resetting all the user data the same screen keeps coming up.
The problem is now I can't flash the stock firmware back because the s-off from sunshine is temporary and now of course it is back on.
Any help or advice would be appreciated
Thanks for reading

Howdy all,
I'll try to keep things brief but informative.
Yesterday I got the unlock bin for my T-Mobile Oneplus 7 Pro. I unlocked it, flashed LineageOS (latest 17.1), Magisk (19.04 but then updated to latest after install), DM-Verity, and TWRP (unified Q version).
I have installed Nethunter, F-Droid, and some other basic apps.
I just got a new SIM Card from T-Mobile and activated it last night, however it shows the same as the empty SIM slot (which my phone doesn't have a physical second slot) and on the lock screen at the top left rotates between saying: "No SIM card" "No SIM card - T-Mobile" "No SIM card - No service". In the phone the top right does not show any bars, x'ed out or otherwise, however one time after taking it out, googling, then putting it back in it sis appear x'ed out until reboot.
I cannot send texts as it says no preferred SIM card selected, and I cannot make calls due to a lack of service; however, I can receive texts and calls and even answer calls and speak to the calling party just fine.
I was getting nothing, then I saw where someone received a text and it fixed it for them, so I texted myself, got a backlog of texts, but nothing else came of that.
I have no idea what to do from here and only vauge idea of why it may be like this but no understanding of it.
I found this reddit post seeming to detail the issue, but I do not know if it applies to me (presumably does) and I do not understand any of the information in the post, nor do I know what to do with this information:
reddit.com/r /oneplus /comments /gb5jlk /factory_reset_no_sim_card_detected_oneplus_7_pro /
(sorry for the spaces, can't post outside links until after I've posted 10 posts)
and with that I'm all out of idea and knowledge. My background is in Offensive Security, but I know very little about SIM Cards and smart phones so all help is greatly appreciated!
Is the device sim unlocked?

I didn't do it so I'm going to assume it is not. I've only unlocked the bootloader (obviously). How would I go about unlocking the SIM?
Also, the original carrier was T-Mobile and the SIM is also T-Mobile, I assumed this would be ok but is there an issue since I didn't unlock it yet I installed custom stuffs - or what would be causing an issue by not unlocking it? (just trying to learn more )

How did you root?
Did you grab a patched boot image or did you boot with the TWRP image and install Magisk yourself?
Grabbing the wrong image is the number one thing that causes WiFi and SIM issues.

Flash Rom again
Flash TWRP again
REBOOT TWRP
Flash Magisk 19.4!!!! <----This version
Flash DM Verity zip file <--- Always last file before system reboot
REBOOT SYSTEM AND ENJOY"
Gotta unlock for custom ROMs. Flash back to TMobile firmware do a sim unlock, then you can flash back.

I got the T-Mobile stock everything back and everything locked back down, but my SIM card is showing now service now - the same no sim message as was on LineageOS, not even receiving texts now.
I'll re-seat and mess with it when I get some more time.

Also, I went to the unlock app and it says it's fully unlocked already and can be used with any carrier...
If you didn't use the msm tool to get you back to the T-Mobile firmware, then you probably aren't on T-Mobile firmware. I had the same issue trying to get lineage to work, and was able to get back to stock and have data.
Since you probably don't have the bootloader unlock code, you need to convert to international firmware, and fully update to at least 10.3.2 before you flash lineage. If you don't, you won't have service.

I did use the MSM tool, it's locked, has the T-Mobile boot animation and everything.
I do have the unlock file & code, I had to wait a week to get it.
