Sim Unlock ZVG lollipop

Hey guys!
I have searched through the forums and found a solution to unlock the sim card on the sprint g2 ls980.
YOU MUST HAVE ROOT FOR THIS
download: https://www.mediafire.com/?tomzuzno01m8zgi
1) Install R.E manager from the rar file. OR any other root browser.
2) copy the carrier files in the /carrier/apps folder and etc files in the /system/etc folder. Make sure you change the permissions to 0644 after pasting.
3) Restart your phone
4) you should receive the signal but the data would not be working.
-Enter ##DATA## (##3282##) in the dialer
-Hit APN Setting
-Hit menu button, and Reset to Default. That should get it working.
5) To get rid of handsfree activation:
install shortcut master, select the search, keyword lte, find com.lge.SprintHiddenMenu.iot.LTESetting, click on the launcher, appear after selecting Operation Mode tab, change the options for Lab Network, the machine will automatically restart, no more handsfree activation pop up.
P.S this is not my work, i just eased the method from two threads.
Special Thanks: @linyincsz @scottdanpor @ysabxe

I used the one click method and was able to use AT&T service on this phone. See my post in the one click forum.

Yes, it will still be unlocked. But you'll have to activate data connection again (step 4) or config apn manually.
And about permissions, you'll have to change them for all the files you copied.

Glad to hear

IS these files copy with Total commander ?
copy the carrier files in the /carrier/apps folder and etc files in the /system/etc folder

If total commander works, yes. Otherwise you can use any root browser

Add L24 LTE bands to BND-L22 or BND-AL10?

Just got the phone bootloader unlocked (thanks to Wh1t3Rose for the guide) and now need to add the LTE bands from L24. Settings > About says the model is BND-AL10, however, HCU client says it's BND-L22 so a little confused. Can't find any fw in firmware finder for L22 so assuming AL10 is the right model.
Can I now safely use HuRUpdater to flash BND-L24C567CUSTC567D1B344 (8.0.0.344) FullOTA-MF on this device? Or I am missing some steps like rooting / installing TWRP etc.?
Another question - what TWRP to use with HuRUpdater? Would the first one from here work for 7x?
Thanks for any comments!

If you need to change model bands , it takes more than that.
If you do like that , the model number doesn't change and modem bands also stay the same. You will need to do what is referred to as "re-brand" which changes the oeminfo file , then flash the l24 full ota.
Changing the oeminfo. Makes bootloader lock again. But the same key is supposed to still work.
It can be easy to make brick during re-brand
. You should Study the bnd-hwota-eng script to understand the process.

Thanks mrmazak. Is this a viable option of getting L24 bands on AL10?

Found the L24 oeminfo here. Is there a way I can backup the oeminfo from my AL10 just in case I brick it
Maybe installing TWRP and taking a full backup is a better idea but can't find a TWRP img for AL10 Naugat :|

I will look at it tonight when I get home.
I had found good hwota tool with the re-brand script in it. I had to translate from russain and add L24 oeminfo but ithas been used successfully.
I will look at that linked oeminfo and compare to the one I put in the hwota tool.
A search on the 7x main page for "bnd hwota- eng" or similar should show the tool like.
If you don't find Ivan upload again.

Thanks again, mrmazak. I saw your post in the other thread while searching but wasn't sure if there is more up to date information or an alternate tool.
Is it possible to just add certain bands to a model without removing existing bands? The only bands of interest are LTE 12 and 17 that are missing in this. The person doesn't really care about Oreo or Nougat - as long as it works with AT&T

Thanks mrmazak for updating HWTOA. I'll try rebranding AL10 to L24 tomorrow. Don't see a way to just add new bands so rebranding L24 seems to be the only way for now.
BTW, I took a backup of Boot, OEMInfo, System and modem_fw partitions. For some reason backup of Data partition failed after multiple attempts (unable to find partition for path /system and createTarProcess() ended with error 255). Is Data partition important in this case? The phone has no real data or app installed anyway as it's not in use.
Another question - planning to use HWOTA7 since I have Nougat right now but downloaded BND-L24C567CUSTC567D1B344 (8.0.0.344) full OTA - is this ok? I can't find a Nougat version for L24C567.

I flashed from L21C10 to TL10,before that I saved 8 modem files with L21 to him and the emui tweaker from the phone,then I restored it,and I had 4G+,try so.

There is a nougat full it's. It is labeled for Oreo roll-back. But should work for you . It is found as 'bond' intead of 'bnd'. ( Wait, the rebrand script is looking for three files. I will try and adjust the script to not fault out with just two.)
And link is actually in the hwota thread as a downgrade package.
I do reupload most current hwota file yesterday. I found a bug when I did a downgrade. So I proof read through the files again and re-uploaded.
Also added link to bnd-hwota-eng to the guide thread.

Did you do this to rebrand the phone to support other LTE bands? Or just to get OTA updates keeping the same radios? Sounds like latter.
I am trying to get the US radio bands on my AL10 by rebranding it to L24.

Ok, will wait for the updated script. I downloaded rest of the files.
In the oeminfo folder I see AL10C00 img but not AL10C675. Trying to root the phone to be able to copy custom.bin/oeminfo so that I can go back to stock later. For some reason SuperSU doesn't work... will try Magisk now

I have been looking at some ways to edit the script to make it automatically adjust if there is only 2 update files. And it will be easier to just manually edit the one script before you run it.
Add a "#" to the front of line 332 of hwota.sh.
"HWOTA_BND\HWOTA7_BND-eng\hwota.sh"
Need to just comment out the line with "$TARGET_UPDATE_DATA"
Code:
echo
echo "Copying recovery files, please be patient and wait...."
$ADB push $RECOVERY $RECOVERY_TMP
$ADB push $RECOVERY2 $RECOVERY2_TMP

Cool, done commenting #332. Also was able to root and make a copy of custom.bin / oeminfo.
Now, going to run the script :fingers-crossed:

Alright, an update - it went through lot of steps as expected (including installing oeminfo and unlocking the bootloader) but ended up with "software update failed" error on the phone. On command prompt here is the last few lines of the log -
Use the volume buttons to select YES and press the power button

Error for update_data_public.zip was expected and on close inspection I noticed there was an extra '.' in the name of update_all_hw.zip. It was update_all_hw..zip.
So, fixed it and put the phone in fastboot mode and re-ran update.bat. It installed recovery and asked me to put into TWRP. I tried but it never went to TWRP started installing the previously copied ZIP files. It took a while but after it restarted, it went to straight to Android (YAY!). Went to Settings > About and say the model as BND-L24 and build number System 5.1.0.98(07DV).
So far it seemed everything was fine - then I inserted the FreedomPop SIM (uses AT&T towers), added the fp.com.attz APN and restarted it - AND the same issue, can't see the carriers and 0 bars
The oeminfo was definitely installed as I see a lot more options in "preferred network mode" but selecting Global or LTE or anything else does nothing...
Since I am not able to boot into TWRP, I wonder if that's causing an issue. Every attempt to boot into TWRP goes into a screen showing "installing update" with 5% status. It eventually (after 10 minutes or so) boots into Nougat.

Gave up and started from scratch (after installing TWRP img mount manually) and it completed successfully (with expected error for the missing update_data_public.zip). Build number changed to BND-L24C567B150 so both zips were installed yet the problem remains the same - no cellular connectivity and settings > More > Mobile Network > Carrier remains disabled...

It’s just that the L21 is always 4G,and on the TL10 it goes to 3G,I switched from L21 to TL10 because of gestures, now I have 4G+ as well as on L21.

Good catch with the renamed file. You did right thing to start over, because that first build number was not correct.
As far as I know this should have changed the radio files (modem).
I will keep looking for other confirmed way to change the selected bands.

Thanks mrmazak. What could be the reason behind disabled option? Earlier with AL10, I could go inside and see AT&T listed but selecting that would not help as corresponding radios were not enabled in AL10.
Now, even if L24 radios are not properly installed / enabled, I should be able to go inside and see AT&T listed - makes me wonder if all the radios are now disabled.
Is there another way to check what radios are available in a phone by running some app?

Not sure about other ways to check the bands. There are playstore apps that will show what band you are connected to, but have not seen one that shows which ones you can connect to.
side note::: Funkyhuawei (paid service) says of there rebrand guide, that you must flash the new firmware at least 2 times. So maybe take the flash one more time.
some general questions about your problem.
On about phone screen, what is shown for 'baseband' ?
does the imei # number show?
are you installing sim into slot #1 ? (#2 does not support 4g)
did you verify freedom pop sim is activated? (tested in other device)
edit:
found few posts in some "rebranding" threads, that say what you want to do might not be possible.
They say on the software side it will have drivers for the correct bands. But he hardware may not suppport it.

There are 2 long numbers for the baseband - both start with 21C60B. Yes, both IMEIs show and are the same as before.
Yes, I always used the dedicated SIM slot as I have a micro-SD inserted for backup.

I am inclining towards this as well - possibly missing hardware
Now, how do I get back to AL10C675 (don't see a Nougat option in FW Finder) and original radio? HWOTA doesn't have C675 as option, it has C00. I do have the original custom.bin and oeminfo but how do I create a zip to install with TWRP?

My complete bootloader unlock and root guide.

So I just got this phone just for fun, it was 75 USD, and went straight to XDA to root it so i can remove some bloat etc. but holy moly i ended up have 10 tabs with different guides open, i have compiled what I did to get this phone rooted.
I want to thank everyone who made different threads about rooting and installing Magisk on this phone, i have read so many guides now so i cant remember their names!.
BUT THANK YOU!.
Let's get to it
Here is what I did for to unlock the bootloader, install magisk and root my Huawei P20 Lite ANE-LX1
First you need to install HiSuite: https://consumer.huawei.com/minisite/HiSuite_en/
and then install ADB and Fastboot drivers: https://dl.google.com/android/repository/platform-tools-latest-windows.zip
(extract the platform-tools folder to the root of your C: drive)
Plug in your phone and let it install drivers.
Then you need to downgrade your firmware to 146 using Dload method, as DCU Client can't read the bootloader unlock code on newer firmwares.
I used "Huawei P20 Lite ANE-L21 Anne-L21 8.0.0.146(C432) Firmware Android 8.0.0 EMUI 8.0.0 05014YXX androidhost.ru.zip" (https://androidhost.ru/6ti)
When finished downloading, open the zip file, open software and copy the folder "Dload" to the root of your EXTERNAL SD CARD, not internal storage!.
Now take your phone and "dial" *#*#2846579#*#* go to Software Upgrade -> SdCard Upgrade and click OK.
Your phone should now begin installing the old firmware, when the phone first boots up, dont set it up, turn it off and hold Volume up + Power and select Wipe Data/Factory Reset, Wipe Cache, and then reboot.
With the phone booted, enable USB Debugging (Settings > System > About Phone > version number > Tap it 7 times to become developer, AND click OEM-Unlock, then go to Settings > System > Developer Options > USB Debugging).
Now we need to buy 4 credits from DC-Unlocker (4 Euro) ( https://www.dc-unlocker.com/buy ) when you have 4 credits on your account, go and download https://hcu-client.com/download/hcu-client-v1-0-0-0287/ Password: hcu
extract the contents of the zip to a folder called HCU in the root of your C: drive
Open up HCU.exe, type in your username and password (check your mail, the info will be there).
Grab your phone and dial *#*#2846579#*#*, go to Background Settings -> USB Port Settings -> Manufacture Mode and press close.
Plug in your phone and let it install drivers.
Open up HCU client, select Unlock, and then Read Bootloader Code.
when you have the code, save it!
Turn off your phone
Hold volume down and power, now we are in fastboot mode.
Open CMD and write:
CD C:\platform-tools
fastboot oem unlock YOUR UNLOCK KEY HERE
Accept the stuff and unlock your bootloader, your phone will be factory reset, and all your data lost if you dont have a backup.
Turn the phone off and on again, set it up, and go to settings -> System -> System update, and update, mine was ANE-LX1 8.0.0.162(C432)
Now re-enable USB Debugging option in Developer Options.
install Magisk Manager (https://github.com/topjohnwu/Magisk/releases/download/v18.0/Magisk-v18.0.zip)
Download patched_ramdisk.img (https://mega.nz/#!GWp1ia6R!xUcg_T_17v1ktlFQPq-Ujo4DRKfAg8E4-_k2J2zLO60)
and place it in the root of your phones internal storage
Open up Magisk Manager, press install -> install -> Patch Boot Image File -> find the patched_ramdisk.img and click OK.
Now open CMD and write:
CD C:\platform-tools>
adb pull /storage/emulated/0/download/patched_boot.img
Now you should have the patched_boot.img in your platform tools folder.
Turn off your phone, hold volume down and power to get to fastboot mode.
in CMD write:
CD C:\platform-tools>
fastboot flash ramdisk patched_boot.img
reboot your phone and check if magisk was installed correctly and check if you have root.
Hope this works for you!

Great guide. Just a tip instead of using cd C:\platform-tools you can shift+right click on the adb folder and click "open powershell here". Saves some time

Thank you for this, but I have a question about this part:
Then you need to downgrade your firmware to 146 using Dload method, as DCU Client can't read the bootloader unlock code on newer firmwares.

Mine is ANE-LX3, what would be the equivalent to 146 so that DC-unlocker can read it?

Yes, you just need to find a firmware for LX3, i dont think flashing a 64gb firmware on a 32gb device is smart.

I have tried that and PowerShell doesnt Work on my pc(i have replaced shift click shortcut so its CMD indtraf) and i wanted a noob proof way to make this work
And thanks.

Where could i find the correct firmware of ANE-LX1

Just use the address bar

Maybe you already know but I learned that you can just clic the address bar in a Windo(w)s system and write 'cmd' which is exactly the same as 'open a command prompt that starts in this very specific folder'.
E.g. in attachments.
Now I just want to know what firmware to downgrade to :/

Maybe you already know but I learned that you can just clic the address bar in a Windo(w)s system and write 'cmd' which is exactly the same as 'open a command prompt that starts in this very specific folder'.
E.g. in attachments.
Now I just want to know what firmware to downgrade to :/

Sweet thanks!.
Try and use this firmware:.
https://androidhost.ru/9V2

Using that as a reference I found one for my region I think (C69) that says:
Integrates Google security patches released in Apr 2018 for improved system security.

Is this April FullOTA a safe security patch to work with DC-u?
ANE-LX3C69CUSTC69
An another one big question: I am in the believe that my P20 lite is Single-SIM. Does it matter if that FullOTA (or any ROM/Update.app/etc) says DUAL-SIM? Should I look for the oldest Single-SIM??? or a Dual-SIM file would work just fine?

If its single sim, you need a single sim firmware and just use a firmware under 150, you should be okay

Would someone like to pay for me cuz I don't got a way to pay i don't have any credit cards..i know this is stupid but im just a teenager and my parents wouldn't pay for it so here i am lol

You first flash 146 firmware with Service menu.
Then unlock bootloader
Then update via the settings menu

thank you very much for your guide, brugernavn.:good:
I arrived without problems at the point: "Turn the phone off and on again, set it up, and go to settings -> System -> System update, and update, mine was ANE-LX1 8.0.0.162(C432)"
but the phone can not find updates ... (i before was in 150) but this isn't a problem.
My doubt is on how to install Magisk Manager (https://github.com/topjohnwu/Magisk/...gisk-v18.0.zip) .... with TWRP ?
Thank you again

what software are you running now?

no signal - a2lite 4gb

Hi,
I did something wrong with my A2 Lite, i've updated the Magisk boot file from the Magisk app. Caused my phone to stop booting Android.
So i tried reflashing it with Mi Flash in EDL mode. That worked but i don't have any signal when i put a SIM in.
It shows my provider in settings so it recognizes the SIM but doesn't do anything with it.
Tried 10.0.13.0 manually and via Mi Flash = no signal
Tried 10.0.2.0 via Mi Flash = no signal
Loaded TWRP, switch A/B = no effect
Does anyone have a clue what i can do now?
Looks like the IMEI numbers are 0.

I don't know how you got here, but it looks like some important stuff was overwritten.
The mobile network is probably blocking you due to the invalid IMEI...
This is typically something that is stored only in the phone's flash. I'm not sure you'll be able to recover the phone.

It might be. In theory. You'd need to know the format of whatever was overwritten.

You can't rewrite the IMEI, I've have that issue before and I created a guide on how to fix it
https://forum.xda-developers.com/mi...-to-fix-efs-corruption-sim-card-t3928910/amp/
Enjoy ?
You can download the latest rom and install it (ignore the rom that's in the guide it is outdated, but the rest of the guide stays the same).

Thanks, will check it out the next couple of days.
I do see some websites/youtube video's of people/apps claiming it is possible by re-writing the QCN file...
I do know where i made a mistake, i tried to manually install all files in an image folder, including flashing a not-so-good QCN file...

Works partially!
I cannot install the latest "QPST_2.7.453" due to "Installation errors".
If i try "QPST_2.7.422" i can restore the created QCN but i cannot select "Enable Multi-SIM" and it only restores IMEI-1

Works now! both IMEI's are now shown in the settings.
IMEI SV is still at 0 though.
Your manual needs some work though.
Latest QFI: https://androidmtk.com/download-qualcomm-flash-image-loader-qfil
Enable Multi-SIM is not in all versions. I've used v2.0.1.9
Restoring QCN with this version can take a while. DO NOT USE PC until done!
8. daisy_sprout:/ $ su
/system/bin/sh: su: not found
127|daisy_sprout:/ $ setprop sys.usb.config rndis,diag,adb
setprop: failed to set property 'sys.usb.config' to 'rndis,diag,adb'
16. is not "QPST.exe" but "QFIL.exe"
20. 21. 22. not needed. directly went to 23 from 19.
stopped at 27, rebooted phone, IMEI's are back. Did not proceed with the manual any further.

How To Guide No caller id on VOLTE/VOWifi calls

For anyone searching..
I was facing the "no caller id issue" on VOLTE/VOWifi calls
The solution for me was always this guide.
However, this wasn't a stable solution for A12, as the made changes to the modem config were gone after a reboot and defaulted back to ROW Commericial. My own network wasn’t available in the PDC list as well (NL KPN)..
Then I recently started playing with the firmware flashable img from xiaomifirmwareupdater.com (fw_alioth_miui_ALIOTHGlobal_V13.0.3.0.SKHMIXM.zip in my case).
I had extracted the modem.img , opened it with powerISO and I found that the PDC tool wasn't showing my specific network because my network wasn't listed in one of the txt files in the folder \image\modem_pr\mcfg\configs\mcfg_sw.
However, the right modem config file (mcfg_sw.mbn) was available, deeply nested in the generic folder.
(\image\modem_pr\mcfg\configs\mcfg_sw\generic\EU\KPN\Commercial\NL).
So there are a lot more (hundreds) configs available than the PDC tool shows!
Not knowing which txt file I needed to change to add my network, I boldly replaced the default ROW commercial mcfg_sw.mbn file (\image\modem_pr\mcfg\configs\mcfg_sw\generic\common\ROW\Commercial) with the one I found nested.
- Saved the image file.
- Replaced it in the firmware zip.
- Flashed the edited zip file.
- Boot into system
Success!
I now have a working VOLTE/VoWifi after each reboot!
Checking with the PDC tool afterwards. It showed that my own network was automatically chosen.
No root acces needed!
Good luck!

Hi there landgenoot,
Came across your topic. Facing the same issues overhere with KPN on a Mi10tpro.
Can you tell me how you extracted the modem.img from the firmware. I did my research but not way I could find the modem.img file in the firmware (extracted with winrar)
TY

hi there, problem solved. your solution was great and working for me too!
Thank you very much!

I guess it can easily be an universal for Xiaomi Devices

I also tried this method on a Poco F3 device, but it didn't work. I am from EU\Slovenia and my mobile operator is Mobitel. I found the settings in the file structure
\image\modem_pr\mcfg\configs\mcfg_sw\generic\EU\Mobitel\Commercial\SI\mcfg_sw.mbn
and copied them to the
\image\modem_pr\mcfg\configs\mcfg_sw\generic\common\ROW\Commercial\mcfg_sw.mbn
in the modem.img file, but I still get an unknown caller ID when using VoLTE.
I also added the path of my carrier settings to the text files (mbn_global.txt, oem_sw.txt, oem_sw_j11.txt and oem_sw_l3a_global.txt) that were missing at
\image\modem_pr\mcfg\configs\mcfg_sw
hoping that would solve my problem, but the caller id didn't work in that case either.
In order to check if the settings for my operator are correct, I also tried the process with the QPST and PDC tools. This time the caller id works, but the process is really complicated, especially with root access in the ArrowOS I'm using and I don't want to do it every time I upgrade.

Sorry it didn't work for you. I assume that you properly replacement the edited modem IMG in the firmware zip and flashed the edited firmware?
Perhaps you can also try again using the same config you chose with the PDC tools

I did try I think three times even with different national mobile providers (A1, Telemach), but it didn't worked. For now it is working because I set it up with PDC tool. I guess I will try again on next update of ArrowOS

Do i need to unlock the bootloader to flash the firmware and how do i flash the firmware?

These instructions are for custom roms only. If you have any of the available custom roms installed for Alioth, you already have an unlocked bootloader. The firmware can be applied in recovery.

I've been searching high and low for a solution, and this one is so relatively easy.
There is an other way to do this, if you've already a working connection with PDC.
- extract the correct .mbn file from the firmware with your suggestion.
- start the PDC tool
- chose load and then chose the .mbn file
- activate it on the sub0 and sub1
- reboot your phone and check if it still works.
Thanks a lot!!! Because I used the wrong modem config, it reseted itself on reboot. Had to use PDC every time I rebooted my phone. Now with the right profile, it stays active.
