[GUIDE] Xiaomi Qin F21 Pro with US Bands - General Topics

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.

[Q] Operator/Network Branding Removal Help

Is there a way to remove branding on the LG P920? I bought the phone outright but it is filled with useless stuff from Optus here in Australia and i am with Vodafone.
Any help highly appreciated!

Just curious,how much does Optus charge for a outright phone,i thought they were available only on the $59 plan.
Dont know if these are any help,but they will remove Optus voicemail and other garbage :
HOW TO TURN OFF ALL OF OPTUS'S GARBAGE
1) Dial ##002# -> Turn off diversions. It works, but only partially.
2) Dial ##21# -> Turn off call redirect. Don't ask me what the difference to the above was.
Now, this is supposed to turn off ALL redirects (below), but Optus STILL didn't want to give up it's useless services! I had to disable them seperately.
So you will need to:
3) Dial ##67# -> Disable Busy redirect. People will NOT GET CHARGED if you're on the phone, and simply get a 'number busy' error.
4) Dial ##61# -> The phone will RING OUT and the caller will NOT GET CHARGED for useless voicemail, which whilst still apparently 'disabled' from above.. Isn't!
5) Dial ##62# -> The caller will simply get a 'phone not available' message, when Out of Coverage area or switched off. No charge-incurring voicemail.
Now, time to turn off useless services like Missed Call Services, which are redundant anyway.
6) SMS 'OFF' (without the ') to 159 -> Disable 'Missed Call Service'. You may get an error, but just keep spamming this number over days/weeks and it will eventually work.
7) SMS 'OFF' to 147 -> Disabled 'Call Recall'
Wow, so much info. Thank-you for taking the time to post all that. I bought the phone from Telechoice for $679, sold my iPhone 4 to get it lol.
I am trying to remove all the icons an menus on the phone that relate to Optus Zoo, there is so a lot. Also there is an Optus screen at startup. My call services are all working fine with Vofafone sim eg; Voicenail and diversions.
root your phone then install root unstaller you can remove anything

Cheers Mate, really appreciate this solution you have given me, when i can read more info and find an easy way to root that i am confident with i will give it a go. Only been using Android for 3 day's and don't know much yet. It's not easy from what i read here. I am used to the simple jailbreak tools for iPhone for the past 3 years.

Goto settings then applications then development turn on usb debugging
then connect the phone to your pc
download this http://www.megaupload.com/?d=IKMS0QN3
extract it run super one click as admin click root after it's done reboot the phone
you should see superuser app on your phone
SuperOneClick should be done in less than 20 seconds, if it's stuck then you probably need to load the proper drivers.
Download the LG Mobile Tool from here: http://www.lg.com/uk/support/mc-support/mobile-phone-support.jsp
Run it, set your country and language in the options menu and then press the Install USB Driver button on the right. Doubleclick on LGP920 and it should download and install the proper drivers. If for some reason the LGP920 doesn't show up in the list you can select another country where it's available (The Netherlands for example).
Then follow ik911's instructions again and you're rooted. I recommend getting the Busybox installer from the market and run it once you're rooted to get all the proper tools a rooted phone needs.
Adam ,be careful when you root this phone,several people on this board have bricked their phones after rooting it, unless the branding is severely annoying you then dont do it,its not worth the risk.I dont want to be the one who says "i told you so ".
Thanks for the info you all have provided. I feel that i am confident in the methods supplied but will head Bolino's advice and wait a little longer before i root the phone.
Regards to all for taking time on this,
Adam
I thought you could only brick it if you rewrite the bootloader, but that you can mess up the rom and recovery partitions as much as you like, as restore of the default LG rom/recovery partitions would be possible with the bootloader and software on PC...
Is this wrong? if so, how does it work?
or is this an special case of extra brickability with the Optimus 3D that i should be aware of, and not install common root apps like CWM recovery or ROM managers?
(I ask because I'm getting one in the morning, and will no doubt root it immediately,.. then after that ill gain root access to to OS..)
Thanks

verizon galaxy siii programming mdn required on non-stock roms?

Relocated from email discussion:
Hey, great tool[editorial: I think in reference to: http://code.google.com/p/cdmaworkshoptool/ ]. Would it be possible for me to get a copy of the most recent build? I'm looking into some things on the galaxy s3 because we lose the min and phone number on non-stock roms. -C
to C:
Most recent build is .2 which is public.. What exactly do you mean by lose? As in they must be reprogrammed after.a rom is flashed? Does the, normal version of dev term you have downloaded fail to write the number back?
3:39 PM (2 hours ago)
to me
It's a temporary problem with cm10. Development has been slow. It's lost on the first reboot and then mms doesn't work. In android, under status about it lists "My Phone Number" as unknown and Min as unknown. Just trying to see if I can write them while the OS is booted.
to C:
To write a mdn and min typically you would connect to the phone in diagnostic mode.. Send mode offline. Send spc. Then simply write mdn and min from the nam part of the interface.. There are typically three nv items which dev term writes for mdn, and min. Then, mode reset will reset and you can confirm if this wrote the nv item..
Did that answer any questions?
to C:
Having never tested a galaxy s iii I'm not sure if devterm should work... There is alot of chatter online about a program called ets, you might look.for that if devterm doesn't work. Please let me know if you are able to successfully write on the galaxy siii.
to me
We are able to write to it with qpst. I actually got the numbers back, but I'm not sure how. Now Im in the process of seeing if I can figure out how to replicate it. What is supposed to happen when you put it into reset mode? It doesn't work for me after that.
to C:
After mode reset the radio of the phone will literally reset.. Some phones this will actually turn off and on the whole phone.. Some will just show no.service temporarily... After mode reset.cdmadevterm will disconnect.from phone.. There are alot of variables, but typically if.qpst could write the phone devterm should also be able.. The mdn and min are really quite simply three nv items, I suspect the subsystem that normally stores this information is being overwritten or formatted by cyanogen...
if you have ever used cdma worksop or qxdm the mode offline and mode reset is functionally the.same..
to me
Thank you so much for going back and forth with me on this. I really appreciate it. The only major difference I noticed between an nv dump on stock and cm is that cm has a lock code for some reason. What is this ETS software you're referring to? CDMA workshop is a bit too expensive unfortunately.
Although I am not totally familiar with the tool it is linked on XDA in another section:
http://forum.xda-developers.com/showthread.php?t=1696621
I wonder if this might have something to do with the chipset not being qualcomm? On the other hand if you said it worked with qpst maybe they are somehow compatible?
The VIA tool probably won't work since we do have a qualcomm chipset. I still have not figured out how i managed to get it to work once but it came up with the unlock sim message I put in the code for my phone that I Found in nvram and then I tried the spc and a few other things and eventually hit dismiss. It said that it could not connect or something to that effect. Then I checked and it had my phone number as 000-000-xxxx which xxx was that unlock code. Then I restarted and I had the number again. I'm wondering if I somehow got the phone to let go of how its storing the phone number.
Hm. If it is qualcomm I would think that cdmaDevTerm should work... this is how one would normally write the mdn and min with devterm:
http://www.chromableedstudios.com/techninjutsu/howtowritemdnminwithcdmadevterm
Perhaps if this doesn't work you could include the response to the NV write from the LogQ tab to help understand the behavior? Maybe the rom is activating a different Nam profile or something?(I'm not sure if I even have a spot on the UI for that in devterm but a log might help understand)
(for logging purposes you may want to trying writing a fake phone number for privacy)
I guess my question also is: are you trying to figure out why the rom does this? or just a good way to fix it when it does?

[Q] [HELP] Heat and signal problems on ZTE V970

Hi to all, I'm writing here because I had my first problems with my v970 (with etotalk rom). This evening I checked my mobile and I found that none of the sim was active (I was not in airplane mode) and I could not activate them, as if they were not in their slots. Meanwhile the upper part of the device began to heat up, so I tought it could be an antenna/receiver problem. I almost forgot to say that I installed Truecaller (deleting Contapps) and updated facebook and few others apps less than one hour before the event, but I already uninstalled them to exclude some of the possible causes. I'll gladly listen to any advice. Thank's in advance. GL
Restart, and see if it continues.
Already tried a lot of times, with or without sim cards. I also noticed an abnormal use of battery.
When did the problem start? What did you do before it started? Does your cellphone always have no signal, or does it come & go (sometimes SIM works, sometimes it doesn't)? Have you checked your APN settings?

The problem started yesterday and I never experimented It till now. As I Said, before I encountered It, I updated some apps from the market and I changed the default caller manager (should I call It in this way?) with Truecaller. I also deleted my sim contacts
. I can't check apn because there are no apns to check (Android shows me the voice "mobile networks" but I can't select it
Update: I tried to restore the original rom, but the problem persists. I also made a check with the recovery, and it shows me that the device cannot detect sim cards. I begin to think that it's an hardware problem (ouch). Am I right?
What did you do in recovery that checks SIM cards? Are you talking about CWM recovery?

Nope, it's the faulty recovery that etotalk sent me with the phone. I would like to install the cwm and flash another rom, but I'll leave that as the last option
If the recovery they sent you is faulty, then what good is it? If there's a custom recovery available for your phone, you might as well go with it, not that it'll solve anything by itself.
You might try inserting some kind of shim along with the SIM card to see if the extra pressure help make contact with the leads. Careful, of course, that whatever you stick in there doesn't stay behind.

I know about the recovery, but I was trying to don't invalidate the warranty (as if I'll ever use it...). Now I'm charging the phone, it's already the third time today...
Aw, heck. If you've got warranty, just send it in.

Yep, I've got warranty, but sending it in China will cost me almost as much as buying a new one
Ok, I flashed a recovery and a custom rom, but nothing happened.The signal is still absent and the antenna heats up the same way as before. I tried to enter engineer mode and it shows me messages as "com.android.internal.telephony.CommandExcepti on: RADIO_NOT_AVAILABLE", "3G off. Cannot set", ecc... It also shows me "invalid IMEI" if I try to look at it and I cannot change it back with the AT +EGMR command (it says "Radio on" and "SIM State: ABSENT", altough the SIM card is in its slot).
I think you have to crack the case.

Hmmm... if your phone is reporting invalid IMEI numbers then I would try first to get that working as it should. Read this tutorial and re-write your IMEI numbers.
Then I would try the latest stock ROM, which is available on ZTE support website. Here is the direct link to the ROM.
If your phone still doesn't work after that, then I'm afraid you have a hardware problem.
I have had the telephone for more than one month with no problem. Trying every ROM made by Bruno with no problem at all with signal, but...
About 4 days ago, I started suffering exactly the same problems stated by ArcheoGian. I have tried everything (installing older Roms, rebooting, changing SIMs from 1 to 2, etc.) but unfortunately with no success. I just have to try to install the original ROM, but I supose it will be the same.
Afer a few reboots, I can make the telephone to search for a network, it founds it, it connects, it transfers data, I can make calls, but ramdomly (can be after 30 seconds, 30 minutes or maximum one hour) it disconnects and the red X of death (Xbox 360 times ) appears on top of the screen.
I can try to go and return from airplane mode, or search for networks that it won't re-connect.
I fear it can become a typical problem for this phone.
I am "delighted" to send it back to China and wait for two months to get it back (after explaining it to the seller and so on). Fingers crossed
@prinxo: did you buy it from eto...k? (I don't know if I can write the entire name of the seller)
Update: I tried everything it was told me (except to crack the case, at least not yet...), my last hope is to manually insert the IMEIs inside the data folder. There's just one problem: none of the methods suggested in the link posted by bcgngm works on my phone, so I need to generate the IMEIs whit my pc (I couldn't open the exe with windows 7, I'll try with win xp in a while, otherwise I have to ask someone to create it for me).
ArcheoGian said:

No, I bought it from another seller at Aliexpress.
As I thought: I tried to re-install an original ROM, and everything remains the same. I thought I was successfull but after one hour the phone disconnected itself from the network. After that moment, I need about 3 re-boots to get signal again and it lasts for just a few minutes.
At this point, I would disregard a software problem.
Happy happy to have to send it back to China.

Why do you say it is not working? My preferred method is to use the adb commands (and for that you have to install Android SDK). Don't forget that when you type the commands there is no output message on the screen. The phone has to be restarted so that changes take effect.

The third and the fourth ones are the only methods to restore IMEI I didn't try, just because I never used sdk and adb (and I'm not sure to be able to use them). I followed the others options (I also created the IMEI file with the russian program), but it continues to show me the "invalid IMEI" message. Can you help me, maybe showing me a good walkthrough?

Options with Motorola Razr M at Red Eye

Hi, first time poster hoping for some help with my first encounter with Red Eye at bootup. I have a stock phone. I don't really care about the phone but my wife really wants the pictures off it. It doesn't have an SD card or cloud backup and the pictures are on internal memory. I am able to get into the boot options (like AP fastboot) but I do not know what the options will do for me exactly. Can I choose an option that may fix the phone but will not wipe the memory? Is there any possiblity a PC can see the phone at the Red Eye screen if I connect with USB(would a certified Verizon data cable help?) Would actually opening the phone and doing some sort of mod get me any closer to retrieving pictures? I am a complete novice at this kind of thing and only have experience with PC hardware and software and the like.

none of those options will be of any direct help, however fastboot may be used to try and fix it later.
first,
- do you know what caused it to become like this?
- is it bootloader unlocked? if you dont know what that is, there will be some dialogue on the fastboot screen. status code=0 locked or similar.
- do you know what version it was on? if you dont know, did you always update when available? would likely mean latest version.
- do you have a windows pc available, with a usb 2 port, and a cable to connect the phone to it?
edit,
ultimately, this is where we are headed, if you want to take a look at it. specifically the "rsd flasher". i was going to go another route, but this is probably a more direct option.
the rsd flasher will take you to another site, and is made by samuri. im not real familiar with his tool, but know its good. just will save me time in having you tear the fxz apart and flash certain things.
**note, im not sure if this phone was made for multiple carriers, this will only be relevant when getting the correct fxz file. samuri will know more about this than i would.

Not exactly sure what happen to the phone. My wife tells me one minute it was charged at 26% and working fine, the next moment it was 'dead'.
It is locked with a status of 0
My Wife says if the phone had automated updates(if stock phone is configured that way) then yes she has all the updates. If updates require manual intervention then it's probably not updated.
Yes, I have a Windows PC with 2 USB ports and a generic data cable that fits the phone.
I'm looking at the post you linked too now... Thanks again for your help!

no problem
its likely your phone is fully updated, but since we arent 100% sure, its going to be best to go with the most current file. reason being, because you are locked, you can only flash = or forward. if you try to flash back, it will either not work, or bootloop. usually not work.
it would probably be best if you continued this in @SamuriHL's thread for the rsd flasher. he is very helpful, will likely be able to quickly point you to the most current file, and will be able to answer any questions about the tool where i wouldnt.

Need help undoing what my old roommate done to my phone

A guy that is apparently a hacker hacked into all my devices and have been controlling my phone. I just don't know how to get him off. Here's 2 pics of the recovery log.
It's taken me 2 months of reading different forums to kinda figure out what he has done to my phone. I just don't know how to fix it and get him completely off. Right now he can control all apps and anything I do on my phone. If I need to upload more logs I will do that.
I see NO logs whatsoever here. Can you please add the logs?

Yes sorry I thought I did put them up here's 3 pics I'll post the rest in a minute I'm gonna get an app that will generate logs.
If this post vanishes that means he deleted it. If been trying to post here for over a month now.
How did you find out he hacked you?
What's your phone model? (Edit: from the logs it is probably a Moto G Stylus 5G 2022)
(PS I saved those photos so I have them even if they're deleted)
@HackD_1 you might be able to reflash the firmware if you're scared, but I still want to know how you found this out (it would be helpful) and if you know what exactly he did.
Sorry for the delay in response.
Yes my phone is a moto stylus 2022 5 G.
I found out after a series of events took place that ended in me catching him on my network. When I confronted him and told him I got a screenshot is when the attacks really started.
He hijacked my network by installing openwrt on my router. I had TMobile home internet and they supply the router so I couldn't just go buy a new one. I eventually got a new router but he just did the same thing to the other one. It got so bad I had to just turn my internet off. In the beginning the attacks would be in direct result of things happening. He moved out but he still has my phone under control. When I buy a new one he just hacks it this is phone 5 in 2 months.

Im actually not sure what all he has done. I do know he uses system apps and changes permissions. He uses project treble to get system root and then he somehow has root privileges over on the phone. He can delete or just turn off any app he wants. It's so complex it's hard for me to even explain. Here's logcat logs hopefully it will help so you can help me.
I tried to reflash the firmware with the moto rescue and recovery but it stopped half way through. He messed the computer up so bad I can't even get on it without him knowing. Then he stops all downloads that have to do with fixing the phone.
It's extremely aggravating.
Ok this person is extremely intrusive and seems to be targeting you.
I have a question: the TMo gateway already runs openWRT, so how do you know he has access?
Did this happen to all your phones? Does he have physical access to your phone?
Can you reset your PC from Windows recovery (or settings if it is a Mac)?
And how do you know that he did it?
Can you boot to Recovery (volume down while powering on) snd send a pic?

@Cheshire147 @HackD_1 Don’t use that MediaTek flash tool; it won’t work in this case.
You should use RSDLite (Motorola’s internal flash tool; it works on 10/11 in my experience if you don’t plug your phone into a blue USB port (usb 3.0) ) to flash this (firmware for US retail version of the G Stylus 5G 2022).
and @HackD_1 The extent to which people on XDA can help you with are with tech related issues. If this gets serious, please report this to your local authorities.
Also, backup and reset any other devices (you said your pc is messed up) to remove any makicious software lingering on your computers, and DO NOT give this person access to any of your devices to make changes.
You should also change you WiFi password and take ALL devices off the network (for security purposes).
@HackD_1 Also, how come you now have 5 phones? You can reset all of them and sell off / give away the ones you don’t want.

I know there's only so much people on here can do. This whole thing has really been one of the worst things that's happened to me. People don't think about how much loosing control of your cell phone will stress you out. The aggravation I felt in the beginning of this because I didn't know what was wrong or how to explain it so everyone would say things like. It's possible to control a cell phone but it's HIGHLY UNLIKELY your phone is hacked. The helplessness I felt from not even being able to get tech people to believe me was unreal.
It's already gotten worst. There's no money in it for him so I thing he is getting bored with it all.
Worst part about all this and imagine how helpless you would feel when you finally say ok enough is enough and call the police just for them to say there's nothing they can do.
So here's what I know. He hacked into my network. Once on he could attack my devices. To get into the device he used either Google apps or Motorola app or even system update then once I unknowingly click his package it's game over
Project treble gets enabled and the recovery partition gets a genteric system image from AOSP once his OS is installed on my device he controls it like a developer building an os except he does things to stop me. I'm not even sure how this is possible if my bootloader is still locked.
I did read something about project treble and being able to flash certain images without unlocked bootloader so I guess that's how.
I wish i could have gotten the MOTO R&R to work but I think he did something to the download file. If I'm downloading a file he don't want me to have he will do a man in the middle and take away from the file or add to it to mess it up. I've download the Stock OS fir the stylus probably ten times. He will mess them up during download or delete them when he sees them in my phone.
I don't even have a computer anymore because he screwed mine up and got it stuck in boot loop.
If I had a USB OTG cable then I could download it onto a USB drive and install windows but mine unfortunately broke.
I have a question. Can I flash the phone using wireless debugging and another phone using tetmux or something similar?
He probably has tetmux configured to not flash it.
It seems every solution I try he has blocked.
Also if I flash the phone will that delete all the partitions? He has a bunch of partitions I've noticed. He's been kinda quiet these past couple days. Usually this post would have been erased and me blocked from this site.
He is also using my USB interface to gain access.
Rmnet. I know he's using it but can't figure out how to stop that either.
@HackD_1 flashing wirelessly is not going to work.
If he was intercepting requests to Google/Motorola servers (although idk how he signed any system apps for update), you should first fix your PC and network before trying to flash your phone.
You can order a Windows usb from eBay or something if you need windows now. And keep a USB around next time.
And can you remove all connected evices from the router configuration and change your wifi password?
