Unfortunately there's no root on MM, root only on Lollipop.
By the way, are you really on z21z? do you experience problems like fingerprint error, cant uninstall app, etc?

i'm on v21z am experiencing bootloop, i thing flashing is the only solution but can't flash it with any version lower than v21z or else it will kill my device.. what can one do in a situation like this

But were you experiencing these problem before bootloop?
About your problem, its likely hardware problem so you need to go to a technician. Or if you want to do it yourself, there're some youtube links about it.

[Q] Unknown Baseband, will you help a technician in need?

Hello everyone!
I got this G920V today,
Basically I need to achieve fully functional Hebrew language in that device.
I searched for custom roms and nothing with Hebrew on it..
So I took my time to explore it.. just a couple experiments(TECHNICIAN RAGE)
I installed Flashfire and tried to install G920F system partition from stock rom G920FXXU1AOD4 ILO.
The phone is on and fully Hebrew working as well but no baseband & no IMEI
Tried Flashing modem and EFS backup from Flashfire but without success..
If anyone's asking, Morelocale is not a solution..
I will try Messing with it with my boxes, but I would prefer a safer solution
If anyone can help I would gladly return the favor !
Thanks in advance!
P.S dont worry about bricking anything if you got some experimental ideas, everything is working if I flash original stock rom
I am experiencing the same thing when I flash G9200 into G920A. This is the first time I've ever seen just flashing "system" messing up with baseband. Anything you have found out?

Mobile Upgrade Q is complete GARBAGE! Stuck on Eluga Switch software. Need help!

I have been attempting to get Mobile Upgrade Q working all day and have had no success because of one stupid little error message...
There is no greater software version available to upgrade your phone, actual version of your phone is the latest.
I can already tell you this isn't true.
To make a long story short, I was aiming to unlock the bootloader on my Idol 3, downgraded to Lollipop via Eluga Switch restore software, installed TWRP, rooted, then attempted to flash Lineage OS 14.1 to the device. It refused to boot, no matter what I did...
Deciding that I wanted to go back to stock firmware, I installed Mobile Upgrade Q 5.1.8, opened the program, and tried to start the upgrade process. However, I was instead greeted with the error I mentioned above, how my device was allegedly already on latest software.
- I've tried using other versions of Mobile Upgrade Q with no success.
- I've tried reinstalling the Alcatel drivers via. the one I copied from my phone to the computer, same result.
- I've tried loading it from the bootloader, and with the device powered off and charging, both of which failed.
- Yes, I've tried wiping data/cache, and even system. I also tried Panasonic Eluga Switch again, which succeeded, but again, I don't want my phone to be branded under Panasonic, and I do want the Marshmallow software...
- I've tried restarts, multiple different drivers, and even relocking the bootloader, all of which failed...
Does anyone know how I can get the Upgrade software to work? I've tried everything I could on my side, and nothing seems to succeed...
Thanks in advance...
Your only chance is to use QFIL and flash stock ROM. You need to google and try to find a suitable ROM. May i suggest 4pda.ru website. It's russian but google translate does well enough. It has a lot of useful information for both variants, 4.7 or 5.5 version . Idol 3 is the worse when it comes to rooting, flashing etc. Don't mess with it. You can easily ruin it for good.

Thank you for the response...
Do you know where I can find the stock firmware file? I couldn't navigate through 4PDA that well due to the Russian interface, and Google Translate did little to no help.
Thanks

Here you go. Use google translate for more details.
If your model is 5.5 you can find it in this forum.
That's all i can do for you. I know it's not much. Sorry about that.

Hi guys! I have alcatel software that restores your phone back to stock similar to mobile upgrade q. It wipes everything back to factory rom. Just let me know if you want the link and instructions on how to use it because it can get a bit complicated.
Hi, I'm having trouble with the mobile upgrade q software. Can you please share any links/instructions on how to possibly get this working? I have a 6045O which was already upgraded to MM and now I'm stuck...

Hello @chewyboy0, you mean flashing latest stock ROM or just wipe partitions?
Hi, the software does wipe and then it flashes the latest stock rom, I do not have the phone currently but I can update on the procedure once I get the device since I have upgraded to a Samsung galaxy note 5 and I gave the old idol 3 to a friend

It would be nice, I'm sure many people will use it.
Hi all! Sorry for the late delay but I have not had the idol and still do not have it unfortunately. I will upload the software to google drive but be mindful that it does require a password to actually get into the program as I assume that it is used in Alcatel's factory to install the software update to the device.

Hiya! I have a guide here: https://forum.xda-developers.com/idol-3/general/guide-restore-idol-3-to-factory-rom-t3769739
I'm not sure if it will work with the Idol 4 but if it does not have the model number listed in the program you might want to try updating it using the dialog box that pops up at startup. Before updating the program, try seeing if it has your idol 4's model number listed and then if it doesn't close out of the program, reopen it, then update it.
Hope all goes well,
Jason

Lost LTE and dual sim not recognized after russian MM update 4.7 6039

So... i install an "update" MM for 6039 but at the end of the update I realized that the rom was only a sim and also did not connect the 4g so I decided to return to my previous rom (LineageOS 13) but the problem was still so I decided to use mobile upgrade, I finish the download, I installed it correctly and when I started the stock rom I realized that the problem was still going on !! I honestly do not know what I can do to solve it, please someone who knows something or who can help me. I would be eternally grateful to have helped me :crying::crying::crying:
Sounds like the phone does not have the correct modem installed.
Try to find the original modem files for your phone.

Please Help Me😭

I was trying to root my phone but i failed, doing so many wrong steps,now my samsung a7 is bricked, i cant charge it and i cant power it on, i also tried connecting it to a pc but the pc cant recognize it, any advice please to fix this? I really dont know what should i do now, thank you so much guys.
Can you talk us through the steps you did.
Is usb debugging enabled?
You may be able to use the samsung flashing software to recover but if you missed 1 or maybe 2 steps and have now wiped the device fully then you need to RMA. No os then no proof of your actions for a warranty claim to be rejected
enter download mode and flash firmware from Odin3

Im really sorry but i was actually not hard bricked, i thought i was hard bricked and i eventually got it turned on, so here is the whole story, i was about to root my phone and i watched a tutorial on how to but for some reason i trusted myself and didnt watch the video so i got into this situation, i enable USB debugging and OEM unlock( it deletes all of my files like a factory reset) i didnt know that i have to paste the magisk and the magisk apk to my phone and i flashed the bootloader thing from the tutorial i watched and then after that i decided to watch the tutorial and to my surprise the tutorial paste the magisk, so i panicked, i dont know what to do and i thought i was stucked at the downloading process so i decided to search more while panicking and i found that tenoshare Reiboot and Ult has this feature that will exit you to the downloading and now i tried them both but it failed, and i panicked more because now my phone just wont stop bootlooping so i just decided to drain its battery because its built in, i also tried flashing twrp but it cause me more panicking because it kind of glitches more so good thing i tried to go to downloading again by connecting to a pc and it worked, and the good thing is that the file i downloaded has a recovery flashable thing so i flashed it again, i escaped the teamwin bootloop and now i tried researching more causing me to figure it and i think i need to download the firmware again, but here is my biggest problem, i dont know the original place of the phone(i only know the country because its like a phone given only to me) i also dont know what is the original patch security of my phone( idk if its safe to just download the latest of the firmware) thank you for any advice

All you need is the correct firmware for your specific model number for your specific region/carrier and the firmware must have a binary that is equal to or higher than the binary of your currently installed firmware. The binary is indicated by the 5th character from the right in the firmware build number. Find that character in the build number of your currently installed firmware and compare it to the same character in the build number of the firmware that you want to flash. If the binary of the firmware that you want to flash is equal to or higher than the binary of your currently installed firmware then you can safely flash it, if the binary is lower than the binary of your currently installed firmware, you will not be able to flash the firmware that has a lower binary.

Hi, i just wanna know if i want to root my phone, is it important to unlock bootloader? And if yes, how should i do it in a samsung a7? Thanks!
Hi, i was planning to root my samsung a7 but i have a question that i dont know the answer, if OEM Unlock is enabled, USB debugging is also already enabled, why my OEM unlocked says bootloader is already unlocked even thought its still blue and not gray? Do i need to void my warranty and make OEM unlock colored gray or is blue enough? Thanks for all advice
