[Q] G2 iunlock and no GSM service

Hi all,
I know that many of you have the same problem and I found that you have the thread about it.
But it's too long for me to follow up. So anybody to tell me what exactly I should do for this problem? When I press volume down + power to go to SimUnlock process, it has a error: MCCMNC, CID failed. On the phone, It can be searched the network.
Please help me, sorry for my bad english.
Thanks and Best Regards
Nguyen

well since you are too lazy to read whole thread...
return the cellphone and get a new one.
Btw, did you tried to unlock it after OTA, or you have not did the OTA upgrade yet?

I did it with OTA not upgrade yet.
You know, the thread about it is too long and sometime I read but cannot understand, it's hard for me to follow up to find the solution. So I want s.o help me clearly and exactly what should I do for this problem, and maybe, it helps others too.
Regards

As I said, return the phone and get a new one. At this moment there is no fix for unlocked phone that is not connecting to any network.
Personally I've tried to find the answer for wether OTA solves the issu BEFORE unlock, since from reports I've read that once unlocked and not working OTA does not helps.
Also iwas trying (unsuccessfully) find what OTA really upgrades.
Good luck.

Hix, I'm living in Vietnam and cannot return the phone to T-Mobile.

sorry but I have to laugh, dude you need to read the entire post to understand the severity of the issue.
return your fone cause its done no service no fix.

I tried to contact with Tmo but there's no reply from them until now. Further more, many people got this problem too and no solution for this.

AT&T Samsung Galaxy S4 mini (SGH-i257)

Hi guys,
I know this doesn't belong here but since I couldn't find the thread for the AT&T device I decided to post it here.
I have a handful of SGH-i257, this is the AT&T version of the S4 mini. As you might imagine the booloader is blocked and I don't have that much time to dig in to the unlocking process (I have tried) but I managed to root it and extract the images (boot, radio, efs, system, etc.) So if someone is interested in this please let me know and I will be more than happy to help.
Thanks

Hi guys,

Ramping up
The AT&T i257 is great news! I have a Telus i257m, and these phones are great. They are like the i9000, so much potential!! Now that a larger carrier will be pushing them I hope we can get some developers on board and start getting some ROMs up!

We do have a thread started at http://forum.xda-developers.com/showthread.php?t=2520299 where we're trying to get the stock images for most, if not all, the carriers. Do you mind uploading them there?

Does i257 have a notification led like the Verizon version? If so, anybody test it with light flow?

Hallo can you please post or email me step by step root process for this device? would be good to know, my friend was asking me to help him with that.

If you have the current and up to date firmware, you won't be able to root it. Knox will block any root access

Correct me if I'm wrong, isn't the locked bootloader is the one preventing from rooting? There's plenty user around with Knox and rooted... Just with the Knox flag triggered and void their warranty.

Hell, I'd be happy if they would just give us the 4.4 update...

I'm trying to root this phone and would really be interested in more information as well. None of the recovery images will flash using Odin ("auth" error), and none of those automatic rooting apps have managed anything either.

I have tried every version of Towel Root but to no avail. It is my understanding that the dev that created this exploit is now working for Google and to my knowledge, there will be no more updates! I can only hope that someone here on XDA that's way smarter than me can pick up the baton and get things going again. Probably easier said than done but I'm very hopeful!

Need help rooting an LG V20 h91810s?

So I am interested in rooting my LG V20 h91810s. From what I gather I have to roll it back to 10j or i. I have the bootloader unlocked already. But I'm not sure about the rollback. Will a factory reset take it back to 10j or 10i? If not, I haven't been able to find step by step instructions on doing this. I think once I can get it rolled back I should be able to follow https://forum.xda-developers.com/v20/how-to/instruction-to-root-h918-10i-t3536472 in order to root it. Any help or comments would be greatly appreciated. Thank you very much.

No can do..... You will make your phone into a paper weight.

So there is no way to root it? I need to root it in order to recover some very important texts. If it can't be rooted does anyone know how I could recover a deleted sms thread?

Thread title changed on OP's request

Thank you very much.

As of right now anything 10p or higher is ARB01. Which means you can't roll back to root. Trying will create a brick. There are people working hard to make it happen but until then it's a waiting game. As for the recovery of SMS hopefully someone can help you. Chances are if you've searched and searched for an answer with no luck, it'll be hard to get that answer here. But you never know. Good luck.

Ah, that sucks. Well tyvm anyway.

We are both on the same boat unfortunately, we'll have to wait patiently.....

Me too waiting to root my h91810s.... hopefully someone will find a method soon.....

Sucks! But I like this phone. It'll be a shame to switch. ?

might be a dumb question but has any of you guys tried kingroot?

Yeah no reason for you to try... Cause of it works we would be rooted Samsung style using flashify instead of twrp.

No I remember I used it to root get the used flashify to flash TWRP.img then flashed magisk and removed kingroot after. If someone with a unlocked boot loader could try it because they had many requests for root

Care to interpret what exactly they did to root? Where to get files and how to? Maybe this can be changed to English format.....

Just wondering if there's a progress thread for the h91810s exploit. I just received mine and it's on the same firmware.

OP5 bootloader relock and reencrypt

I've done some searching and I couldn't find any straight forward info about how to relock the bootloader and reencrypt my OP5.
I'll sell it but the buyer asked for it.
Can anyone shed some light and/or direct me to a thread I can rely on in order to do so?

if the customer wants it all stock, u can use that unbrick tool. it'll get ur device all stock again (I guess). do some research bout it before, as I'm still a newbie nd this may just seem a bad idea.
Good luck!✌?

You can have it even simpler(https://forum.xda-developers.com/on...bootloader-flash-twrp-t3704592/post79512430), but it's also a way.

Unlocking the Bootloader

I just bought this is a second/work phone. I would like to get rid of all the extra software, root the device and possibly flash another ROM in the future. SInce this is my first Xiaomi device, I am wondering what is the procedure to unlock the bootloader?

From searching, it sounds like the only way is to REQUEST it via this procedure (requires SIM, MI account, and TIME/waiting for approval.):
https://www.getdroidtips.com/unlock-bootloader-xiaomi-redmi-7/
I'm wondering if anyone knows if that is absolutely the ONLY way, or if one has the Redmi 7A phone physically, there is some way to root/unlock boot loader.
