Is it possible to CID Unlock via the Manual Bootloader?

Is it possible to run some type of application that would CID Unlock through the manual bootloader for Tmobile Dash? Or maybe a way to manually do it?

It has been suggested on this board that if you use the "upgrade only" rom in the ftp, then you can flash your phone with the roms available without cid unlocking your phone. I have tried everything with the information received from the helpful people on this board, but it seems that the methods suggested work on some Dash phones but not others. Give it a go, I haven't bricked my phone trying yet. Good luck.

When I try the UpgradeOnly ROM, I get the same error as everything else. ERROR 300: INVALID UPDATE TOOL... any ideas? I thought I remembered seeing somewhere that you can add /something tag when you execute the file in DOS to circumvent this error but I can't find where I saw that.

Interesting, I haven't seen that error yet. Mainly I get Invalid vendor id for the upgrade only rom.

Does nobody know the answer to this question? Moderators? Or does anyone know how to circumvent that error?

same mess on the htc rom
I have now tried for 3 hours but i get the same error message. My T-Mobile Dash is unlocked, so all I am trying to do is make it a clean HTC 620 ROM.
Does anyone know how to help us???
thanks

the invalid vendor id message that your getting is telling me that your phone is still CID locked. you have to CID unlock then run the update util then it will allow you to load the HTC ROM.

basically put -
IMEI-CHECK.com
38 bucks
Done

CID unlock
Any idea how to unlock the CID?? i got the invalid vendor ID error...

Error Code: Secure boot 1002 - What should I do? Please help

Dear XDA community
I recently bought a LG G4 from an online retailer. According to their website they said it was a UK model, which according to the back of the phone beneath the battery it is: LGH815. But then after booting the phone the ROM being used was: LGH815T. Then I typed in the IMEI number and found out it was a: Verizon US model??
Basically I am having trouble identifying my model. The phone apparently came unlocked and rooted, but the person who sent it must have done something wrong because when I flashed a TWRP recovery image to the phone it comes up saying: secure boot error code: 1002.
The good thing is, is that I can boot into the device and still operate it as per usual. But what I want to do is bring the recovery back to normal. I was searching around and apparently there are some KDZ files that can be used just to flash the recovery? Is this correct? If so could you assist me in what I have to do to fix my issue which is: secure boot error 1002.
I would really appreciate any help regarding the matter. :crying:
Tried posting photos, but forum would not let me, all they showed was the model numbers.

Use LGUP-NEW ( https://forum.xda-developers.com/g4/help/lgup-install-kdz-mm-lp-t3249803 ) to install/flash ... the appropriate stock KDZ for your specific model once you ascertain it (LGUP - NEW may recognize your model and you can use that info to find the right KDZ). You will have to re-root the phone if you still wish to have root.
If you do root, suggest you might want to check out steadfasterX's [LOCKED][G4][TWRP][UNOFFICIAL] TWRP-in-FIsH for all locked G4 devices at: https://forum.xda-developers.com/g4/development/locked-twrpinfish-locked-g4-devices-t3573048
It has been tested on locked devices AND unlocked devices. Version 3 Beta 4 and 5 seem very stable and the links are available in the later posts on the site. It works like a charm and has been tested on a quite a number of devices now.
Addendum: I'm wondering if the online retailer may have meant it was carrier unlocked (i.e., so you could use other service provider's sim cards), not bootloader unlocked? That could account for the secure boot error getting TWRP to load.

LM-G710V going back to stock possible?

Hi!
I have this G7 with the model LM-G710V with an unlocked bootloader and managed to successfully flash Phh-Treble by following this thread:
https://forum.xda-developers.com/lg-g7-thinq/development/rom-phh-aosp-8-1-t3808649 :victory:
but then i would like to convert back to stock but unfortunately there are no available KDZ for G710V in the interweb.
would it be possible to convert G710V to G710EM ,or to a similar effect, by flashing 10b Vendor img and boot img then the kdz found in this thread:
https://forum.xda-developers.com/lg-g7-thinq/development/dump-g7-stock-vendor-t3840834 ?
or would this just leave me with a dead bricked phone?
additional notes:
bought this phone as a secondhand from someone in facebook with the bootloader unlocked and with, as the seller stated, "G7+" rom with issues.
no backup was made before
Thank you for anyone willing to answer! :good::fingers-crossed:

Hello @xElouise, according to the LG Open Source Code Distribution website (here), the G710V is equivalent to:
G710VM
G710AWM
G710AWMH
G710VMP
G710VMX
KDZs from any of the models above should work fine, just note that they may come with carrier bloatware. Reflashing the stock firmware is the same as any other G7 version (here, up to the first half step 5).
Does your phone have an IMEI code and working telephony? Because from the info I have gathered on the internet, looks like the G710V is a retail demo unit without either baseband or IMEI.

Hey there! Thanks for the reply!
Unfortunately since after flashing Phh-Treble LGUP does not recognize the phone anymore (Shows up as Unknown)(maybe because i flashed the vendor img(?) idk.)
Anyway, since back then before flashing Phh-Treble i was already trying to flash KDZs Thru LGUP, but unfortunately LGUP throws me error saying it does not support cross flashing.
I have tested the following before:
G710VM - LGUP Error cant cross flash G710V to G710VM
G710AWM - LGUP Error cant cross flash G710V to G710
G710VMX - LGUP Error cant cross flash G710V to G710
This unit IMEI & Baseband says unknown. This also has the white sticker at the back with some of it's details like unit model, FCC Id, etc.

Try hooking it up to LG bridge. It will automatically recognize the phone in download mode and it will update it to the latest stock.

LG Bridge fails to recognize the phone on download mode.
It says " Notice: Can not connect. disconnect the USB cable from your computer and reconnect" done this multiple times, even swapped usb cables with other phone
edit: So i was able to make LGUP recognize the device again but still same problem with cross flashing <see pic for reference>

You can contact the guy that sold the phone to you and see if he has a dump. Otherwise I can pack the system and the vendor but I'm not 100% sure if it will work

Hi, is your unit the demo unit one, without phone function and with retail mode app? Did you encounter any issues with the flashed ROM so you're changing again? I managed to land one of those demo units but there's too much restriction for usage so I was thinking of flashing another ROM but I'm a complete noob with regards to that.
Thanks.

@LameMonster82 , The seller said that he bought it off someone when it has boot loop issues and have his buddy fix it for him & he does not have any backup (guess that makes me a third hand(?) not really affected by it since i got the unit for a dirt cheap price around <$100 and it's quite a smooth unit too).
If you could, in your spare time of course, make the pack that would be really much appreciated! Thank you very much!
@ceezae , This may be a demo unit since i got it without any sim functions and a blank IMEI. I don't know about retail mode, though there was an widget applet before which showcases LG G7's features. I already bought the unit with it's boot loader already unlocked so I have no idea how a G710V got unlocked. When i bought the unit it does not have any audio at all either thru the headphone or speaker that's why i flashed a custom rom.
Anyway , since I flashed Phh-Treble 8.1 the phone's working smoothly aside from the aforementioned bugs in this thread
I am going back to stock since i can not utilize the quad DAC feature in custom rom and I could not get Gcam to work (it either crash or extremely Laggy)
I would also like to mention that:
I can not seem to boot to recovery via (Vol down + Power button) it always say that "Factory Reset is Disabled by Kill Switch" even though OEM Unlock is ticked in the developer settings as well as unsynced Google Account.
And my internal storage is showing that I only have 16 GB of internal (would be easy to fix with TWRP but again no luck with custom recovery)

Hi there!
I am terribly sorry but my device is kinda a bit soft bricked(?) at the moment.
I was trying to flash the Stock Korean PIE KDZ and was successful but it had problems like WIFI can not be turned on and Random Reboots.
I think I also have lost access to Fastboot since the phone only Reboots itself normally.
My dumb self did not make a backup so I am a bit screwed at the moment.

Someone with an intact phone (which hasn't been flashed) will have to pack up their partitions and post it here. The G710V seems to be technically similar to the G710N but can't actually be flashed to a G710N (you can force this through using LGUP but it results in a phone that crashes all the time due to some issue with the wifi driver).

Hey, I tried backing up these via adb shell myself on my G10V but... "permission denied". Great. Probably because the demo units force a Retail Mode device administrator that you can't remove at all. Can't even access the page itself in Settings ("you are not authorized..." blah blah). It's a shame, because I was really looking forward to helping OP.

have you succeeded I have the same problem as you

[GUIDE] Flashing XQ-AT51 Firmware on XQ-AT52 Device

Disclaimer: I am not responsible for any bricks/ issues you may encounter following this guide. Although, I will do my best to try to help you if something were to go wrong.
MAKE SURE OEM UNLOCK IS ENABLED UNDER DEV SETTINGS BEFORE YOU DO ANYTHING BELOW
Update 2: 3/11/2021 : I see maybe deleting the .ta files may help avoid soft bricking, feel free to try it I have not personally tested yet to see if it works.
Update#3 3/13/2021 : If you are following this guide recently make sure you update to Android 11 first! Do not do any updates after the first one to Android 11! Then the flashing should work just fine. Tested and verified this on Taiwan XQ-AT52 to 51 firmware
Hello, I've managed to successfully flash AT51 firmware on my AT52 without issue using Newflasher.
Step 1 download = the US firmware/ whatever region is needed for you and new flasher/ the sony xperia drivers needed to flash the firmware to your device. Extract it to your desktop. Install the Xperia driver from newflasher if you need to/ haven't yet. Newflasher needs to be extracted into the same folder where the firmware files are that you downloaded from Xperifirm. This step is crucial!
Step 2 : Power off your Xperia and put it in flash mode by pressing down on the volume and connecting it to your PC via usb. (Do not use the USB C cable that came with the phone use a different one if you have one) You'll know it is in flashmode if the notification LED turned green and the screen remains off.
Step 3 : Open newflasher.exe
Step 4: type n then press enter
Step 5: type n again and press enter
Step 6 : This is when you should get to the flashing stage. Press Y and enter to everything you are prompted to. type y for yes to. This for me resulted in a successful conversion over to AT51.
Step 7: Once everything is done and it says you are safe to disconnect your phone please do so and then press and hold your power button until the phone boots up.
At this point you should have a fully working AT51 firmware!
Bare with me as I"m working on getting developer access for androidfilehost and will upload the files asap. In the meantime you can download newflasher and the firmware files yourself using Xperifirm if you don't wanna wait for me to upload.
Xperifirm: https://forum.xda-developers.com/cr...xperifirm-xperia-firmware-downloader-t2834142

Can you please help? I followed and i got a corrupted message and power off in 5 second.
I tried xperia companion, failed.
I tried to reflash newflasher with original firmware again, failed.
Please help.

Can you tell me the model of your xperia phone? If you can still get it into flash mode when the notification LED turns green you may still be able to recover it.

Hi, I finally managed to restore it. I have to remove all the ta files to flash it, then it booted up.
Thanks for your respond.

I have using newflasher
After using 3 time xperia companion it work normal again

Hi, I didn't find this thread until after I made an attempt at flashing the device. I followed the instructions from the link below and ended up with the device saying it's corrupted.
https://www.xperiablog.net/2018/01/...-firmware-for-xperia-xz-premium-xz1-and-more/
I tried redownloading newflasher as well as redownloading the firmware I wanted as well as a new cable and that did not help. I reflashed it with this procedure listed above and it did not help.
Xperia companion won't let me do anything because it says the device is locked even though the device was not locked and there doesn't appear to be a way to unlock it. edited to add that I did get xperia companion to repair it successfully
edit again to advise I succeeded only after doing n and enter a third time then hitting y and enter for the final flashing step and that was successful in getting it updated correctly

Would it work to unlock my phone
Thanks for the guide!
Can I ask few questions please?
First is do I need to have my bootloader unlocked? I enabled OEM unlock setting in developer settings but that is only one thing I did.
And the second one is could this flash unlock my phone?
I am in this situation where my AT51 won't work with other sims except for Vodafone. UK.
I stayed with them for 30 days, (required time frame to get your phone unlocked) requested unlock code and it has been more than 10 working days but still have not received the code.
So today I did some searching online and found the service code to check if my phone is locked to a network and to my surprise it says it's not. So I am guessing that they have limited my phone to using only their sim through some other means andnot buy locking my modem. But this is ofc just a guess.
I kept chatting with the customer support and he keeps saying wait for the code which I do not believe is going to come, they have to unlock it on their end. But I am not sure about that. I don't think they are sure either..
Basically I'll wait fem more days maybe they will unlock it but if they won't when I am thinking maybe my modem is not locked and I could unlock it by flashing different ROM?
Or do you think this won't work?
Sorry for a rambling post. Looking forward to your reply. Thanks!

You do not need the bootloader unlocked as you are flashing official firmware.

Anyone know if you can flash a XQ-AT52 to a XQ-AT51 and then back to the XQ-AT52 firmware?
Sent from my XQ-AT52 using Tapatalk

I know this thread is a few months old at this point but I'm really struggling to flash to XQ-AT51. I've successfully flashed from XQ-AT52 Hong Kong (my original firmware) to the Taiwan version which is slightly better because of the messaging compatibility but I really want to get the US version. I have tried at least 20 times over the course of a full day and I have not been able to flash the US firmware without getting an error saying "Your device is corrupt It can't be trusted and will not boot" every time. I have repaired it back to the Hong Kong firmware (back when that was the one I had) and to the Taiwan version once I had that installed. But I have never gotten the US firmware to take without the "Device is corrupt" error.
My phone is the Sony xperia 1 mark 2 running the then default XQ-AT52 Hong Kong, and now running the default XQ-AT52 Taiwan. I've been trying to flash to XQ-AT51 US. I've been using newflasher v39 and the US firmware downloaded for xperifirm v 5.5.0.

So I was able to flash from the hong kong version to the Taiwan version and back with no issues at all. But I'm still unable to flash to the US version without the "Your device is corrupt It can't be trusted and will not boot" error that seems to happen every single time I try to install the US firmware.

Can someone make me a favor and can upload the latest ftf of Android 10 for the Xperia 1ii Single SIM?

The 1 II has downgrade protection, so as long as the firmware version of the US version isn't the same or newer than the highest version you've ever used you're gonna get the corruption error.
What you could try is flashing the newer EU version and then flashing only the older US customisation image. That's what I did for a while since US firmware was older than EU firmware, and it worked. Not sure if it'll work with Android 11.

I know this thread is a few months old at this point but I'm really struggling to flash to XQ-AT51. I've successfully flashed from XQ-AT52 Hong Kong (my original firmware) to the Taiwan version which is slightly better because of the messaging compatibility but I really want to get the US version. I have tried at least 20 times over the course of a full day and I have not been able to flash the US firmware without getting an error saying "Your device is corrupt It can't be trusted and will not boot" every time. I have repaired it back to the Hong Kong firmware (back when that was the one I had) and to the Taiwan version once I had that installed. But I have never gotten the US firmware to take without the "Device is corrupt" error.
My phone is the Sony xperia 1 mark 2 running the then default XQ-AT52 Hong Kong, and now running the default XQ-AT52 Taiwan. I've been trying to flash to XQ-AT51 US. I've been using newflasher v39 and the US firmware downloaded for xperifirm v 5.5.0.

im in the us and was looking to the 256gb version (i think its taiwan). is the hong kong or taiwan version missing anything? or is the only reason to flash to US to get better coverage with us carriers?

It's for better coverage and for VoLTE and Wi-Fi calling support. Also if you get a HK one with Android 11 you will be unable to flash the US firmware, because it is still on Android 10; and the phone has anti-rollback protection.

it arrived on 10 still, but its bugging me to update.

This isn't the case now since the US models have Android 11 too now

Can anyone confirm that this process has to be done using USB 2.x? I've read in a separate post that newflasher isn't compatible with USB 3.x, which is currently what all my computer use. Also, should I be using the newest version newflasher?
EDIT: Tried on USB 2.0 and it worked perfectly.

Question Oneplus 9 pro bricked error with msmtool

Please any one can help me with unblinking my device I already passed all errors except for error called firehose getufsinfo failed anyone help please

Hello! Give us more details about what MSMTool did you used. Where did you downloaded? Is your device recognized by the MSMTool? What OP9Pro model do you have exactly? What region? Is carrier locked? Did you installed the Qualcomm drivers to detect your device in MSMTool?

Make sure u are using correct msm.. And b4 running msm make sure to click to use "use lite firehose" and u csn uncheck sha256 if it isn't msm for ur device amd it shld still work. Also it seems easier for msm to connect if u click enum a time or two til it says connected then click start
