Please Help

This is my first post on these forums and I would like to start off by saying this is one of the best sites I have found and has already taught me so much. Ok so here is my problem. I recently realized that I can unlock my phone (I have a T-Mobile Dash) but I did not know how to go about doing it. So I looked and looked and read and read and decided to pay $39.00 and get an unlocker program from GSMliberty. I’m not sure if GSMliberty is a credible site but I still went thru them. I made the payment and followed the instructions on what to do. I connected my phone to my computer and once active sync was connected I ran the unlocker. Every time I tried this I received this error
I submitted a trouble ticket with the company and they sent me this reply:
"Make sure to run the unlock from home. Run active sync, then connect the phone while it's on in Windows mode with NO SIM or memory card. Rerun the unlock software. Only 1 active sync session must be running on system tray.
ALL firewalls, anti-virus software and pop-up blockers have to be off."
I have no clue how to fix this issue or what I am doing wrong and I am extremely frustrated with the whole dilemma but my question right now is what the heck windows mode is? I have never heard of windows mode before, I thought because I have a windows mobile phone that my device is always in windows mode lol. Anyways I am sorry for this long post but any help will make me feel better. Thank you in advance and once again sorry for this long thread.

I curious, what did you do to get it working? And, is is CID and SIM unlocked?

Yes it is SIM and CID Unlocked. I went thru IMEI-Check instead of GSM Liberty but I found out that if you get this error message while running the program all you have to do is unplug the USB cable from your device then stop the unlocker program, then re insert the USB cable back into the phone and right after that start the Unlocker program again. The program will pick up where it left off. I found this out after trying to get this to work for about a week. If any one decides to go with IMEI-check and they get an error message just do exactly what I explained and everything will work out!!!

EVDO HTC hero sprint

Hello .. I have my HTC hero back on sprint. but no EVDO or DATA connectiuon at all.. I went to the corporate store and of course the MSL code did not work.. so i told the guy well use 000000 and the guy said .. so u messed with the phone...and i had to say yes...therefore they are not messing with it at all...even when i putted the right MSL.. L*( so. what can I do to get my EVDO DATA back?
I can make calls etc...
my other question is...
if you flash your phone..with STOCK(RADIO,STOCK APPS) and you changed the MSL before...will the STOCK flash do all that it suppose to do?

I had the same sort of thing happen to me when I was trying to pass a rooted Pre to a friend. Using the RUU might sort it out, if it doesn't call customer care and ask them to send out the hands-free provisioning signal again. That will put the right info on your phone. Most of all, don't panic All will be well once again.

That's a problem..the hands free activation starts working when you turn oin the phone but it does not complete it gives an error 1012

that's probably due to the MSL not matching the one on file. have you tried rewriting the correct MSL code to the phone? the handsfree activation and profile update should work after that.

Yes I did that...They gave me the MSL...and It does matches the one on file...I am going to try using the RUU again ..

fix
Take the phone back to the store all they have to do is reprovision the phone. If the won't work on the.phone factory reset the phone. I work for Sprint and either will work.

But I am thinking that Update Profile...and Hands Free activation need a EV or 3g whatever connection...right? I don't have it there is no ICON
Just to make sure.. I am running the RUU properly...I have to go to the bootloader( 3 android skaters) and select Fastboot right?

3 things I can think of that worked for me the other day, you will need your MSL and do a ##RTN# (##786#) hit menu then reset. It will ask for MSL but it will also delete everything. should work as long as you have 1.5 based off the 1.29 or 1.56.. Or you can try ##DATA# (##3282#) and reset the data profile. If that does not work call sprint or go into your local store and have them reset your Vision username. 1 of those 3 things should get you where you need to be. If they do not work it is more than likely hardware related.
Just wanted to note as I am still an active employee for sprint as well, a data provision will not work, they will only be able to go these routes in this case, so def. back up any information you may want to keep if you have not already.

ok thanks for all the replies...I just came from a Sprint store, and they guy said that my DATA was not provision properly and I have to wait 1 hour take out the battery ... and turn the phone on again..that should do it...if it does not I ll call Sprint and have them reset my Vision Password ... Thankss!

Ok I think I know what's the problem...First I don't have a recovery thing....HOME+POWER ON brings me to a Exclamation ICON I guess there is where my info should be ... and because the phone was rooted before that image is gone...so the ##3282# USERNAME menu is empty...where can I get that info? that suppose to be there? IP, etc

Your data information will populate automatically once provisioning completes, Id try calling tech support having them reset your vision user name not password then preforming a RTN or doing the RUU prior which should reset everything to what it needs to be prior to root.

thanks man

FIX
It is not the username and password. It is the fact that the phone is not recognizing there is a network available i have seen this issue a bunch of times. you are going to have to do a hard reset (not a ##786#)or you can take it back to the store and have them provision the phone through icss.

I have done Hard Resets more than 5 times. now ... So i am getting a new phone, and that's it .. I'm tired of goind around with my phone..having i consirderation that my phone was in Metropcs and then to Sprint , maybe that screwed something, ahd the guys over in the corporate store don't want to work on it.

if you were in my area i would help!!

Hard resets will do nothing... Run the RUU... Your MSL has no ties to your provisioning.. So I don't know why that keeps coming up.. I'm not sure how Metro does things, but to take that ESN to another carrier usually needs a radio flash and if they had done that, you will not be able to use it unless you reflash the sprint RUU...
You cannot exchange a phone that you have maliciously changed... It has nothing to do with the phone, its the user....

Hey, he bought the phone. There is nothing 'malicious' about him modifying or customizing 'his' phone. The only thing malicious here is your attitude. Well, that and the phone company Nazis warping the brilliant idea that Google had when the Android was first conceived. It wasn't supposed to be about control, or about 'nickle and dime-ing' their customers to death reselling features that are already built into the OS.

[Q] Samsung Focus Unlock Code (ATT)

not sure if this belongs in this board, but Ive been calling ATT for a while now to get an unlock code for my overseas trip.
I got mine, but...
I just don't know how exactly I'm supposed to enter it, Ive been getting mixed messages from each rep involving the steps, but the code seems to be the same.
Can someone tell me how to enter it?
---things they've told me:
- you need a diff carrier's sim card
- you dont need a diff carriers sim card
- you need to enter stuff like (#7563*638*.........)
- you dont need to enter stuff like (#7563*638*.........)

Well I just called ATT and was given my unlock code... The directions given weren't the best but managed to get it unlocked to hopefully I can help.
The woman on the phone gave me a long winded code #746...*638*742.....# Which obviously didn't work since there is no option to type in # or * when getting to the unlock screen. So I just started typing in the different numbers she gave me. I typed in the second series of 742... numbers which was 8 digits in total and hit enter and my phone was unlocked. I should also mention I did have an Australia sim card in when doing this so I'm not sure whether or not another sim is needed in the process.
Hope this helps and you can get it to work...

what is the 742 number sequence they gave you? id like to try it with my unlock code.

I actually left the code I was give at work so can't give it to you ATM... From what I've read all each individual phone has its own unique code so its doubtful mine would work anyway.
Basically what I did is entered the last 8 numbers that ATT gave me with my Aussie sim in the phone. If you're still not able to get it to work tomorrow I'll find my code at work and you can see if it'd randomly work for you.

I still haven't been able to unlock mine.
Could you please give me a step-by-step guide for unlocking my phone the way that you did?
I just need the steps and the 742 number, i already have my code.
Thank you.

Found this (and cleaned it a bit):
How to enter the unlock code for Samsung Focus (aka NCK)?
To enter unlock code for most Samsung:
Method 1:
1. Insert a foreign sim card
2. Enter the PIN if the card has it
3. now enter code NCK
=> the phone should be unlocked
If your phone does not ask for an unlock code:
Method 2:
1. Switch ON your phone with a non accepted SIM Card
2. Compose:
#7465625*638*CODE#
OR
*#7465625*638*CODE#
OR
#0111*CODE#
WARNING: entering wrong code 3 times or more will FREEZE the phone and you will need an UNFREEZE code (another one).
Hope one of above works for you.

Samsung Focus Unlock worked..
Thanks to Zehns10, the instructions worked perfect. Not only the AT&T person spent an hour trying to help me without success, but I also spent an hour with Samsung Technical Support Level 3 guys and it was a total waste of time.
The key to unlocking your Samsung Focus phone is to have a "NON AT&T SIM CARD" with you and insert that in your phone to proceed with unlocking. Both AT&T and Samsung Tech support will tell you to take the SIM card off and try all kinds of stuff and it simply won't work.
Happy camper, I am now!

Yep, my phones unlocked now
Thanks.

I've asked AT&T (just in case) via email and they send me an unlock code with complete instructions including that step (non-AT&T sim card). Total time spent - less than 5 minutes (except waiting for reply, of course). So if you not in hurry, use email

what is the procedure?
i got the unlock code from AT&T
but no procedure.
when I power on I get SIM ERROR
so...where do I enter this lovely code?

AT&T instructions (my copy&paste):
1. Power off the device and insert a non ATT SIM card.
2. Power on the handset.
3. Network Lock will display enter the device unlock code.
4. The SOS key (Left Soft Key) on the lower left side of the device keypad will change to OK. Select OK.
5. Display should read Network Lock Deactivated.
PLEASE NOTE: You only have five (5) tries to unlock the phone. If this process is unsuccessful five times in a row, the phone will be permanently locked to the AT&T network.

Sir, I have got my unlock code. When i enter a non accepted SIM card i am getting an error "Incorrect SIM". It does not ask for unlock code. I want to try Method 2 mentioned by you but i am not quite sure what "Compose" means as mentioned in step 2. Also a few screenshots or a video tutorial demonstrating method 2 will be a great help.
Thanks in advance.

Where can I get the unlock code?

Ask your provider (T-Mobile).

question?
can I ask a really dumb question:
below Method 1 says "3. now enter code NCK" .... Where? using what? the widget that pops up asking for the Pin is a numeric keypad only.
what is it that allows the 'input' of "NCK"???
and similarly, in Method 2, what device/widget/applet allows the input of "CODE" ??
i guess others know this, but so-called "legacy" SIM's are not liked by the i917

I live in Egypt and I won a Samsung Focus S in a Windows Phone development competition (it was held by Microsoft Egypt).
The only problem is that it's locked by AT&T and I'm unable to use my Vodafone Egypt SIM.
I contacted Microsoft here but they keep telling me that they'll get me the code and they don't, so I decided to do this myself.
Can you tell me how to contact AT&T to get the unlock code? I don't think I can call them because that would cost me A LOT (international calls here are very expensive), and tell me what I need to say to them in order for them to give me the code

Contact AT&T via email (see my posts above) or just pay $20 to these guys: http://www.samsungimeiunlock.com/samsung-focus-s-unlock (I hope, $20 is not A LOT for you? )

Ok so I just discovered that I can call AT&T's customer service from Skype for free
So I called them and I told them about my case and gave them my IMEI number, but they couldn't find my unlock code
I asked them what could be the reason for that, they told me that with new phones like mine, the manufacturer doesn't release the unlock codes to the carriers until some time has passed, that time can be a month or a year or forever!
Can someone tell me why would Samsung do this? and does that mean I'll have to use samsungimeiunlock.com to SIM Unlock my phone?
20$ isn't that much (it's approximately 120 Egyptian pounds), but I would've preferred if I was able to get it for free

XDA Q&A isn't the best place to ask rhetorical questions. Forward your question to Samsung. Also, as for samsungimeiunlock.com better to ask samsungimeiunlock.com guys directly (I'm not working on samsungimeiunlock.com).

[Q] Problems with sim unlock galaxy s2 I9100, chainfire and helroz unsuccesfull

Hi there,
I am having difficulty unlocking my new (UK) galaxy S2 and I figured this is the best place to ask for help. I have searched the threads on this forum and have not been able to find the answers I need. So I'm starting a new thread.
I have rooted the phone successfully and followed the instructions with the chainfire app and when it finished it said it couldn't find the unlock code. The phone came from Virgin as part of a contract, however the contract has been cancelled and I don’t have a virgin sim any more so I haven’t actually tried it with the virgin network. It might be worth mentioning here that when I put a different sim card in it the screen that pops up asking for the unlock code isn't there. I have also completed the procedure with the “galaxy S Unlock” app created by Helroz and that was also unsuccessful. Because the three steps in "galaxy S unlock" were unsuccessful I have restored the efs folder back to its original state. I have not bothered to try the manual method of recovering the unlock code using the hex editor because after reading this forum it seemed unlikely to work and it looked like a bit of a hassle.
I have tried several sim cards in the phone that work with my friend’s phone. And my phone was unable to connect to any networks. Except, when I tried my friends T-Mobile contract sim card I connected to the T-mobile network but my phone wouldn't allow out going or incoming calls however the data network worked fine! Yes the internet was working through the t-mobile network (wifi was turned off)
Isn't that weird!!!! So it kind of looks like the phone might be being blocked by the service provider but I find that very unlikely because up until a couple of days ago the phone was sealed in its box.
I have read through most of the "[HOWTO] GT-I9100 Free SIM Unlock via nv_data.bin by Odia" thread and there is some mention of a new locking technique employed by the various phone network companies. Does my problem sound like it could fall in to that category??
It might also be worth mentioning that I took the phone to a phone shop to see if they could unlock it. They couldn't, but the guy did check the IMEI number on a website called checkmend.com and that site reported: "checkmend has a record of this item having been blocked by a cell phone network" and "checkmend has a record that this item is currently blocked by one or more cell phone networks". Does anyone know anything about this website and weather it is reliable or not. Like I say I find it extremely unlikely that it has been blocked because I have only just got it out of the sealed box.
I am very frustrated as you can all imagine and I would really appreciate some help. Feel free to ask any questions, I am a bit of a noob but I'm not completely incompitent so don't be afraid to get technical.
Thank you for listening,
Yours,
Dardarland.

Bump...
I'm having kind of the same trouble here...
I tried the Chainfire's app and it couldn't find my code, so i went and tried the Helroz App
after following the instructiones in the app and checking with *#7465625# it changed network block to OFF... but when i inserted a diff carrier sim it said: network block... and now my other carrier sim got blocked and won't get recognized by the phone it used to be in... LOL
pls help us both!!

Unlocking
Hi
I did have the same problems with the chainfire app
what i did is use Galaxy_S Unlock (google it as I can not post links at the moment)
Also you will need to install busybox for this to work.
just search for busybox in market and install the first app that comes up
Hope it works

Hi fjaraiza,
I saw somewhere in the forum guys that were having similar problems due to the carrier branded rom they had on the phone and due to helroz method which is far more intrusive than odia's. Helroz is flipping bits within nv_data.bin which might lead to corruption. The success of Helroz's method also depends on the phone protection method, some newer versions check the correspondent md5 and ignore the file if it's not the right one.
Your best bet would be to restore an /efs backup if you have one or backup the current state of /efs and try another rom.
Good luck,
Stefan.
P.S.: use thanks when the supplied information is useful

can unlock the messed up ones for a lil fee, pm

Helroz unlocks but then locks again...
Hi all, I've got a weird problem. I used Helroz SIM unlocker on my SGS2 (Im running the latest CM9 build 28/8) and it works. Helroz unlocks the phone but only for about 1-2h?! After about 1-2h the phone has lost NW connection and ask for the SIM unlock code. If I press 'dismiss' then I can run Helroz unlocker again and it will be ok for 1-2h and then loose the unlock again... Has anyone had this problem? Before I used a stock Samsung ROM and then Helroz unlocker worked perfectly, its since I've moved to CM9 ROM that I'm having this issue. Can anyone help?
Thanks in advance

[GUIDE] Xiaomi Qin F21 Pro with US Bands

Xiaomi Qin F21 Pro with US Bands
LTE Bands 2, 4, 12, 13, 17, 66, 71 as provided by the US Qin F30 Kosher.
Things you need:
Windows PC (as far as I know this only works on Windows)
Qin F21 Pro with unlocked bootloader and TWRP installed.
See: https://forum.xda-developers.com/t/tools-mod-scripts-mlgmxyysds-qin-f21-pro-unlock-tool.4368277/
(This can be a headache, there are probably better ways to do this.)
See: https://forum.xda-developers.com/t/...om-firmware-root-playstore-certified.4405615/
You only have to follow this tutorial up to the point of installing the boot_2.img in TWRP you do not have to root if you don't want to. I do believe most of us with F21's probably have already done this entire tutorial though.
SP Flash Tool: See tutorial above, it comes with it.
ADB (and please know how to use it): https://www.xda-developers.com/install-adb-windows-macos-linux/
The files I provide with this link Which are: F30 files (from my purchased F30), my edited scatter file to show new partitions, SN Write tool with provided Database files.
https://www.mediafire.com/file/3fba0dugos3lkdv/F30_US_LTE_Bands_Package.zip/file
I WILL NOT BE HELD RESPONSIBLE IF YOUR PHONE DOESN'T BOOT, SOFT/HARD BRICKED! THIS TUTORIAL IS TO DO AT YOUR OWN RISK!
GUIDE:
1. Write down your F21's Original IMEI, Wifi Mac Address, and Bluetooth Address.
Go into your phone settings and scroll all the way down to "About Phone".
Here you will find your IMEI, Device Wi-Fi MAC address, and Bluetooth address.
WRITE THESE DOWN!!!!!!!! YOU NEED THESE LATER!!!!!!! I even included a txt file for you to do it in!
We want to write these down because we will need them for the SNwriter tool later.
2. Turn off your phone and boot into TWRP, you can do this by holding the heart/owl key (top left) and the * (star, bottom left) key, you will see the Douqin Logo. Keep holding until TWRP boots.
3. Plug the F21 into computer and TWRP will allow ADB connections. We are going to use ADB to pull/backup your modem and identifier files in case you mess up =)
DO NOT SKIP THIS STEP. WE WILL BE OVERWRITING THESE FILES - THEY CONTAIN THE IDENTIFIERS THAT YOU WROTE DOWN ABOVE.
Even though we will no longer be using these files, they are original to your phone, and I think its incredibly important to have a back up. I even included an empty folder for you to put them in!
Use the following ADB commands:
adb pull /dev/block/by-name/nvdata
adb pull /dev/block/by-name/nvram
adb pull /dev/block/by-name/nvcfg
Now find those files and put them some where safe!!!
(You can also use TWRP and copy the files, and put the on a USB stick or maybe some where else on the phone)
4. Turn off the phone again, you can do this from TWRP by going to Reboot and chosing Power Off.
5. Open SPFlash Tool and load the scatter file provided from my files "MT6761_Android_scatter - edited.txt". This will add the NVData, NVRam, NVcfg partitions to flashable partitions.
5a. Uncheck all the boxes we don't need and only check off nvcfg, nvdata, nvram, and md1img_a. These are the ONLY partitions we are flashing. (They should already be selected! BUT SO WILL THE PRELOADER, UNCHECK PRELOADER, I had to include it in the folder for the flashing to work, but we do NOT need to flash it!)
5b. Click the "location" portion of each row and find the corresponding file from the files I provided. (This should already be done!)
5c. When you got everything set up, click the Green Arrow Download button. With your phone turned off, hold the BACK button (top right) and plug it in. It will flash these files to your phone. KEEP YOUR PHONE OFF FOR NOW.
6. Open SNwrite tool on your computer, make sure ComPort says USBVCOM, and Target Type says Smart Phone.
6a. Open the System Config button and make sure ONLY IMEI, BT Address, and Wifi Address are checked off in the "Write Option" (top left) section.
6b. In the DataBase File section (at the bottom) and make sure "Load AP DB from DUT and Load Modem DB from DUT are checked.
6c. Click on the MD1_DB button and select the "MDDB_InfoCustomAppSrcP_MT6761_S00_MOLY_LR12A_R3_MP_V88_3_1_ulwctg_n.EDB" file located in the AP DB Base\\MT6761 folder (within SNwrite folder).
6d. Click on the AP_DB button and seelect the "APDB_MT6761_S01__W1947" file located in the AP DB Base\MT6761 folder (within SNwrite folder).
6e. Click Save and go back to the main window, click on "Start" and a new window will pop up. Remember how I told you to WRITE DOWN all of these from your F21? This is where we need it.
IMEI_1 = your original IMEI.
BT Addr = Your Bluetooth Address (no colons!)
Wifi Addr = Your Wifi MAC Address (no colons!)
6f. Before you click OK be sure to have your phone at the ready. You will need to, just like with SP Flash Tool, hold the back button as you plug it in! Click OK and plug in your phone with the back button held. Wait for the bar to progress and the green PASS signal to light up.
6g. When its done, your original identifiers will be flashed to your phone! Another window may pop up making you think you have to flash again, just close it as long as you saw that Green PASS signal you are good.
7. TURN ON YOUR PHONE AND ENJOY US LTE BANDS!!!!!! 2, 4, 12, 13, 17, 66, 71
These cover most of T-mobile and Verizon users!
Go back into your phone settings as in Step 1 and make sure your original IMEI, Wifi Mac Address and Bluetooth Address are there.
To confirm the bands, use the phone dialer and type:
*#*#3646633#*#*
This will take you into engineering mode (use at your own risk, don't mess with anything!) and click on Band Mode. Scroll thru the bands and you can confirm which ones are active. As far as which ones are currently being used, I am unsure of how to do that just yet. Will update when I know (was told there are apps that might be able to do this).
-----------------------------
Things to note:
AGAIN: BE SURE TO BACK UP YOUR FILES and write down your IMEI, Wifi MAC ADDRESS and BLUETOOTH ADDRESS! I cannot state this enough.
If you do not do the SNwrite tool (section 6 of the steps) you will have DUMMY made-up identifiers, and technically those will work for a while.. but you don't want to have the same ones as others, so please do section 6.
I cannot help you with unlocking your bootloader, that part can be easier and the tool I linked was not fun. There are apparently much easier ways, please look into them.
If you can unlock your bootloader, and install TWRP you can do the rest of these steps easy!

I'd like to thank:
Jbazt_katuforzs (XDA forums) for the Unofficial Qin F21 Pro firmware tutorial.
Sense_101 (XDA forums) who I couldn't have done this without, they helped me with learning ADB commands and knowing which files I would need to get this done.
mosheys (XDA) who told me about SNwrite tool.. which I knew about, but couldn't work before, and gave me the motivation to try again, really made this all come together.
jbriones95 (Reddit) who got me into Dumbphones and introduced me, through his videos, to the F21 Pro. The perfect phone for me!
eitokai (Reddit) who worked on tinkering with the F30 and made me believe I could do it too, and make progress - and everyone they thanked helped too!
Quick shout outs to Highpowers23 (Reddit), and 154FAviator (Reddit).
Lots of other random tutorials online where other people were trying to do similar things with their phones!!

4/25/23: Fixed an issue where SPFlash tool was giving an Invalid Preloader error on Step 5a. I had to add the preloader file to the supplied download, but we do NOT need to flash the preloader. Edited step 5a to reflect change. Thanks to XDA user mosheys for pointing it out =)

amazing. looking forward to trying this out later tonight.

It worked! Amazing. Thank you for putting the time in to write this up.

Wow, and I always thought that network bands are hardware that can't be added...
How's that possible?

Hi
I have been using this flashed US Bands thing on my phone, and I notice there's few places that my phone just gets thrown off service, I can be in middle of a call and the call ends, etc
Also I miss a lot of calls due to it getting thrown off service in certain areas. (not talking here in basements etc, just random on street)
Anybody else experience such issues?

I'm sorry I haven't had any issues at all except for one time when I ran out of data unknowingly. What phone provider are you with? You might have to manually add their APNs to your settings.

That's what they'd like you to believe! It can be mostly true, but since the F21 has a US clone, the F30, I was able to make it work via their files. Next thing I really want to try is adding more bands if possible. But it involves hex editing perhaps which I'm no good at.

If you figure this out . Love my f21 so much since I used your guide

Can someone post a step by step video on how to do this

Will this work on f22 pro also?

Hi there! Thanks so much for the guide and the files
I followed all your instructions with my brand new F21 pro unlocked that I got from aliexpress, 64/4 version. when the phone arrived, it was already unlocked and had TWRP installed. So I went to follow your tutorial from that point. I specifically bought this phone to use on Verizon for a family member that does not use smart phones so this would be big upgrade for them, since most of the options for Verizon basic phones are bad choices.
Anyway, I consider myself fairly intelligent and computer savvy, I followed your instructions exactly and got no errors both times. first, I got the green checkmark after downloading the files then I did the imei writing I got the green PASS with 0 errors
so I go to turn the phone on, the system now appears "kosher." the Chinese play store is gone, etc. the system is telling me there is a software update which I ignore... when I plug the SIM card into the phone, I am not getting any cellular reception, however the phone does see that sim belongs with Verizon. my phone number shows up in the about section, as well as the original imei and Mac and bluetooth address. so it appears my writing to the phone was successful, but for some reason the bands are not active. I can do wifi calling with Verizon but not over cellular.
I really dont think I did anything wrong but I do have a question was the sp flash tool supposed to only say "download" in the drop down box from the first step?? was it supposed to be install and format??? I left it on download because I wasn't instructed to change anything and went about my business but I am just trying to figure out what went wrong.
again, I want to reiterate, the Verizon employee said they did not see the imei I provided to them with my current sim already in the phone, so why could they not see the f21 pro with original imei and lte bands after your guide? was he lying because they do not want me to use this phone? he asked me if the phone was Samsung and I just said yeah, he was foreign and I didn't feel like explaining.
really trying to figure out what went wrong here. it's frustrating that you can get it to work but I can't. I successfully copied the imei, Mac and Bluetooth address so I dont think that is it. when I go to look at the bands in the developer menu, I do not see the bands you mention with a check box next them. does that mean they are not active??
I really dont want to have to return this phone or sell it because it was a gift and it is actually quite nice for the money. so I put the SIM card back in the old basic phone (sonim xp5) and naturally, it is working as it should... this is a LTE sim and both phones use LTE, so I do not see what the problem is
is there something that must be changed manually in the cellular settings after sim insertion such as LTE/ CDMA only or something like that? again I am on Verizon and I have decent coverage where I am trying this.
thanks

it worked ! Thanks for sharing this guide !

Hey there,
The fact that the bands aren't checked off in engineering mode indeed means that the bands aren't active (I did it and the bands showed up) you should of course redo the setup carefully in case you might have missed a step.
About Sp flash tool all you have to press is the green download arrow at the top of the window. And remember to make sure to deselect the preloader partition.
And not sure if I understood you correctly but you mentioned that after you finished the process you got the full kosher version on the phone, that shouldn't be the case because we are only copying the necessary partitions from the f30 for the service to work(I might have misunderstood you on that last one).

I had prepared the phone for the user I bought it for thinking I did al the steps right. when I realized the phone wasnt working, I re did the tutorial. it wiped all the apps and work I had previously done on the phone such as adding the play store, certification, etc and various apps. it was ready to go... so when I did the tutorial again, starting at the step where you load the F30 files, the phone appeared "kosher" when I flashed it and was once again app less... that is what I meant. it looked like I had started over.
was there anything about the bootloader or the unlocking process that may have not been done properly by the seller of the phone? Again, the phone arrived to me already unlocked and with TWRP installed so I skipped all those steps thinking I wouldn't need to do them.
what did I do wrong if I erased all the apps and the kosher version got installed and wiped the stuff I had already done when I tried to redo the process ?? I'm literally just following the instructions on a brand new phone.
the only thing I could think that I did wrong was skip the unlocking process but I only did that because I assumed the phone was already unlocked. I would assume it's unlocked if TWRP was already installed.... am I wrong ?

Do you mean you bought the version with the Google play store ("unlocked") and that's why you bypassed the other stuff?

And now with the kosher version, are you following the steps to fully unlock it first?

I admit I skipped the unlocking part because I bought the "google unlocked world" version from aliexpress, and so I assumed it was done. and in the developer menu it said the phones boot loader was already unlocked... and the phone had TWRP already, so I assumed in order for TWRP to be there, it was unlocked already.
so I guess you are telling me that I shouldn't have skipped it because it wasn't truly unlocked then? okay, I will try it again.
I do not have the kosher version, I was referring to my f21pro phone after flashing with scatter f30 file.
also I just realized that when I was trying to unlock I was holding the wrong two "top buttons" I thought it was the owl button and the back button, not the camera button and the back button

Maybe give the two top buttons a try before trying the full unlock route? Only a suggestion! I also got the google unlocked world version and was going to try putting all of this on here this weekend. Hoping we don't actually have to go through the full unlock process and maybe it was just the wrong button combo!

I've read some conflicting reports about which buttons it's supposed to be. The actual readme says it's the top two buttons (Owl+back) and someone else, an administrator here actually, posted a photo circling the #+back button.... and someone liked that post assuming it was true
also, someone else said you can only get into TWRP by holding the Star and Owl button when the phone turns on then you have to immediately press the up and back button to boot into TWRP... which isn't entirely true... all you have to do is hold Star+Owl button to boot into TWRP...
I will admit I am new to the world of modding phones but not modding electronics which is why I felt confident enough to take on this project. I have modified many iPods with rockbox in my day and done physical modifications. I find this fun but it's teetering on extremely frustrating.
I am going to have to do the entire unlock process from the very beginning because I don't have any other choice, otherwise I am left with a phone I cannot use on Verizon. it will be waste of ~140usd. not the fault of the aliexpress seller, just poorly written instructions and dumb windows compatibility issues.

I cannot get the phone unlocked because I cannot get my computer to recognize the phone via usb. no amount of button combinations are letting my windows computer see the phone so I cannot unlock it.
