currently my phone is stuck at the logo and after seconds it loads Fastboot automatically i cant access the phone os to do anything i used the xiaomi bootloader unlocker app that works online but it didnt work . the local cell phone service shops told that they have to open the phones back case to fix it ... i dont want that i've just bought the phone didnt even use it for a whole month :(
[Redmi Note 11 Pro+ 5G (peux)/POCO X4 Pro 5G (veux)] Braain:
they don't have to open it they use licensed or dongle software (USB type) currently I use unlocktoll.net but if the phone is under warranty and you haven't removed the bootloader before it is better for you. It is possible that others have the same problem as you. Good luck

Rule number 1 for Xiaomi never flash anything on Mediatek devices, it will fail. If messed up, no way back as Xiaomi locks the devices for autorized service providers or local Xiaomi branches only. If you want to play with Xiaomi custom roms/development/etc. related only buy Snapdragon based devices.

I i.e. learned it the hard way, when this all started with the Redmi Note 8 Pro, I bricked it by flashing twrp in Android 11 and Xiaomi didn't want to repair it, so I had to pay some russian guy to fix it via Teamviewer with a modified unlock tool which was able to answer the unlock requests by pasting the answer manually from a generator. It's not like I messed up at a point, it's just that Mediatek devices easily fall in a unrecoverable state. In my term it was the combination of Android version and twrp. You will note there is no Mediatek support on xda and even when your device is named like a Snapdragon version, your device is offtopic here, because trying anything on it beyond unlocking the bootloader is harakiri

how to unlock my bricked Redmi Note 11 Pro 5g (China:pissarro) Bootloader​

Congratulation. Brick without unlocked BL :/

my opinion: you are done....

Some Xiaomi devices have pins on motherboard to

switch EDL, but i dont know with this device.

Try complaint and say something like: "my phone was upgraded and then i see only logo"
[Redmi Note 11 Pro+ 5G (peux)/POCO X4 Pro 5G (veux)] rakesh.aggarwal:
I did the same with my device. You can fix it using the MTK tools guide. Its lengthy but easy.

rule #1 with Xiaomi - bootloader is unlocked :D
[Sony Xperia XZ1 Compact Questions & Answers] asseforlife:
Heya, after switching out yesterday from my first xz1 compact after 3 years to my 2nd one, i'd like to buy spare one, and i'd like to buy a cheap docomo one but will it work in france for the 4g/3g bands please?

is there anything i should be aware of please compared to the g8441 please?
[Sony Xperia XZ1 Compact Questions & Answers] 4qx:
There is a difference in coverage of frequency bands between them. According to Frequency Check docomo does work with existing carriers in France, albeit g8441 has more extensive coverage and might work better in certain cases/areas.

Almost certainly, in case of docomo you'll have to pay to get your bootloader unlocked if you want root or custom ROM on board (23GBP is the price last I checked). There are also small possibilities of either docomo with a freely unlockable bootloader, g8441 with a bootloader which has to be paid to unlock, or docomo advertised as g8441.

No matter the version, I would buy from a place that accepts (free) returns just to be on the safe side. Some ebay sellers offer them.
[Sony Xperia XZ1 Compact Questions & Answers] asseforlife:
Thanks a lot dude!! it's sad that there are some missing bands :(, it's hard to find a G8441 with decent price after having mine for 3 years, i check ebay quite often
[Sony Xperia XZ1 Compact Questions & Answers] j4nn:
This is very interesting info. Thank you.

I am wondering if it could be possible to unlock the LTE band 20 on "docomo advertised as G8441" board?

I just happen to be the unlucky one to get Japanese version of xz1c motherboard unfortunately.
[Sony Xperia XZ1 Compact Questions & Answers] Purplearyes:
I'm probably late, but if you want bl unlocking the docomo version i think it's impossible even if with the mentioned software tool 23gbp, they have some dark magick locking on this version, even if you unlock it, you will run into problems flashing custom firmware :( i think this is all true I've owned a docomo xz1c as my main phone for more than one year, tried everything there is
[Sony Xperia XZ1 Compact Questions & Answers] asseforlife:
It will be only with stock rom using temp root from J4nn, but since unlock 4g band b20 is impossible, I will need to learn to repair my broken one or spending 300€+ for a new one :/
[Sony Xperia XZ1 Compact Questions & Answers] Purplearyes:
I have tried the temp root for SO-02K and it sucks, after you disconnect the cable, root is gone, also its a root that doesn't allow you to do anything really. Useless
[Sony Xperia XZ1 Compact Questions & Answers] tonsofquestions:
The purpose of J4nn's root is not to maintain it or end up with a fully open phone. You'd need to unlock the bootloader and install magisk for that.

The point of it is to be able to back up the various partitions and things (eg TA and DRM keys) that unlocking would normally erase -so that they can be restored...
[Sony Xperia XZ1 Compact Questions & Answers] Purplearyes:
Still pretty useless for our docomo
[Sony Xperia XZ1 Compact Questions & Answers] j4nn:
@Purplearyes , no offense, but the fact that you do not know how to use a temp root exploit does not mean it is useless - it is very useful for others as you can see with other posts in this thread.

Particularly interesting seems to be the post #41 (linked from the OP too), that allows to prepare a setup for root after reboot without need for a PC with adb access.

And it is even more useful particularly for docomo, where you have no other (free) option, as official sony bootloader unlock method is not allowed.

Without the temp root you would not have any way to even try to experiment with diag interface to see if unlock of missing LTE bands could be possible or not.

Unfortunately the exploit is useful not only to us, but also to aliexpress sellers, who use it to cheat us by selling Japan SO-02K model with patched firmware to show itself as G8441 as documented here :-(
[Sony Xperia XZ1 Compact Questions & Answers] Purplearyes:
My bad. Your explanation was extremely helpful. I'm sorry
[Sony Xperia XZ1 Compact Questions & Answers] Purplearyes:
These fake g8441, wouldn't they return back the Japanese version if a factory reset was done? Or do they somehow truly modify oem partitions and are able to integrate them on Japanese firmware? If so, how come we can't do this ourselves, like patch the Japanese boot img with magisk and get root??
[Sony Xperia XZ1 Compact Questions & Answers] tonsofquestions:
Fascinating. I hadn't been following that thread, so hadn't realized folks were doing that.

Unless I missed something, your root still isn't for Pie, right? Only Oreo?

So these folks are downgrading, rooting, flashing a wrong partition, then upgrading again? That's a lot of effort! Or I guess maybe they've found some other non-root method.
[Sony Xperia XZ1 Compact Questions & Answers] Purplearyes:
Utterly fascinating indeed
[Sony Xperia XZ1 Compact Questions & Answers] j4nn:
yes, the temp root is only for oreo

unfortunately yes, checkout my post with firmware version history - you can see there they downgraded to oreo from pie then went back to latest pie - they crafted oem overlays just to make SO-02K appear as G8441 - not nice at all :-(
[Sony Xperia XZ1 Compact Questions & Answers] j4nn:
It is quite clever - it is actually very well done de-bloat of Japanese firmware, plus property overrides to force model to appear as G8441, also switched in TA so that it looks that way even in flash mode. Still not accepting other .sin files than those for SO-02K.

It survives also factory reset.

You can do similar modifications in oem, but that does not allow to get root in pie - they do not patch boot img, only oem. Boot (and system and vendor) partition is checked by verified boot with locked bootloader.
[Sony Xperia XZ1 Compact Questions & Answers] Purplearyes:
Your explanations and Knowledge were an amazing gift. I appreciate it so much. Boosted my knowledge a lot.

Do you know other amazing tools we can use on a non rootable phone like this xz1c beauty. I use obvs utube vanced, i use button remapper for that extra key funcionality without root, i use grenify and naptime with adb. I de bloated with adb ofc.

Do you know more cool stuff? I wanna squeeze this docomo to its max.

Thanks brother

(on another note thinking about buying a g8441 motherboard but they go over 100 euro and can easily be a fake as you mentioned 😅😭🤣😔🙄)
[Sony Xperia XZ1 Compact Questions & Answers] the baz:
I purchased a G8441 new from ebay and had no idea it was a fake till 6 months later when it no longer worked on the Australian 3g 2100 band. (it worked on 4g for data and still did, but the phone would not work) I had a XZ2C Docomo SO-05K and an XZ2C G8314 that was also a SO-05K that had been flashed and sold as a G8314. I tried multiple things to get the VoLTE working but failed. I loved these phones but purchased a Samsung S10e and moved on.
[Sony Xperia XZ1 Compact Questions & Answers] j4nn:
@Purplearyes , @the baz or anybody else - can you please share me TA partition of your SO-02K (or the fake G8441 which is in fact SO-02K)?

I am on the verge of enabling LTE band 20 on my SO-02K, but I need to compare several TA partitions of that model in order to identify ta units that are device specific vs that are identical within the SO-02K model range.
[Sony Xperia XZ1 Compact Questions & Answers] the baz:
Forgive my ignorance , but what is the TA partition?
[Sony Xperia XZ1 Compact Questions & Answers] j4nn:
Check the point "6. backup your TA partition" here.

Basically it is a 2MB partition where sony phones store most of configuration settings specific to a concrete phone piece.
[Sony Xperia XZ1 Compact Questions & Answers] Purplearyes:
I can my friend, but I'll need some time and if you have a more convenient channel of communication like telegram also good stuff
[Sony Xperia XZ1 Compact Questions & Answers] mragonias:
I purchased i fake G8441 which is in fact SO-02K, on eBay, and will arrive on March.

Hi everyone,

any suggestions for a SIP softphone working with a local asterisk server? I used SJphone on my Axim before which worked great, but it seems to crash my HD when editing the profile. Had a quick look at fring but couldn't get it to work (besides, that's a 100% nono looking at the way they manage connections - dont like a man in the middle)
[OnePlus Nord N20 5G] bebop831:
Hey everyone!

So I made a rookie mistake and bricked my Nord N20 5g. I tried flashing what i though was the correct boot.img but turns out it wasn't and now the phone will not leave fastboot mode. I tried looking online to find the stock rom but I wasn't able to find it. Does anyone have any info on this or a way to recover this phone model? Thanks!
[OnePlus Nord N20 5G] DrScrad:
Hey man . I'm glad you started this thread because I only just yesterday received my unlock token from OnePlus. I've been searching throughout the night for the stock firmware (and low and behold, of course I've got the one ****ing OnePlus model in the universe not listed on their official website.. let me know if you make any headway or have any developments and I'll do the same
[OnePlus Nord N20 5G] bebop831:
Yeah it sucks lol I actually contacted support services seeing if I could get a copy of the stock ROM. Sadly, they just said it was unavailable for this device (they didn't give a reason) and that I would need to send in my device to get re flashed.

Do you think it would be possible for someone with a stock phone to dump theirs?
[OnePlus Nord N20 5G] FoMarl:
Yooooo
[OnePlus Nord N20 5G] FoMarl:
Man I legit did the same thing like 5 days ago I have done everything possible to restore it but cant do it. I have a dump of the phone, but i dont know how to make a flashable zip with it. i also have the ofp of the global or tmobile model {not due to a week of scouring} but cant seem to get msmtool to work without an account. also in flashing the wrong file i lost my efs folder so no internet connection what so ever. Here you are goodluck and please let me know if you get it going.
[OnePlus Nord N20 5G] bebop831:
Yeah, sadly I don’t think there’s a well documented path forward. However you mentioned that you had dumped the stock phone? Would you be willing to share that and I can take a look and see if I can keep make a flashable zip
[OnePlus Nord N20 5G] DrScrad:
I'm onboard to do whatever I can do to help us all three facilitate the same need we all share..
[OnePlus Nord N20 5G] johnmpage:
Hi Bradley Scott, I mean, FoMarl,

I would gladly take a look at what you pulled off your phone and attempt to use it to get my Oneplus NORD N20 5g up and running again. I will happily share what I discover as a thank you. Can you zip it up and upload it to a file sharing service? Or send it to me? Thanks, John ( xda at johnpage.net )

[OnePlus Nord N20 5G] Joey_nuss:
nicoblue1504, any word on that twrp? I can't find a patchable boot.img or a stock rom to root and a little nervous about the lack of info regarding rooting this device.

I got you homie... :-*
[OnePlus Nord N20 5G] iKlover:
I think I was able to magisk patch the boot image from the above dump. I'm still awaiting my unlock token, but perhaps someone wants to check? It's the us TMO variant.

Remember to only fastboot boot, not fastboot flash until tested further. It's not TWRP but it will still provide root access if successful.

Edit: Upon trying to upload, it goes to 22% and then stops. How do I fix this?

[OnePlus Nord N20 5G] PsYk0n4uT:
Does a dm verity or anything have to be flashed first? If so where would I find the appropriate file?
[OnePlus Nord N20 5G] iKlover:
I wish I could answer that question but unfortunately I cannot, as I don't know. I was just able to extract the boot image and patch it. I'm still a noob so that question is above my head
[OnePlus Nord N20 5G] PsYk0n4uT:
So I flashed it and it killed my modems I guess. No sim, no wifi, no mobile data
[OnePlus Nord N20 5G] PsYk0n4uT:
The one time in my life I don't have a backup of efs
[OnePlus Nord N20 5G] iKlover:
You flashed it first without testing it out via fastboot boot and not fastboot flash? I'm so sorry it caused you that much trouble. In my experience, you should always fastboot boot first to test it out, as that is not permanent. I'm terribly sorry.
[OnePlus Nord N20 5G] PsYk0n4uT:
Not your fault
[OnePlus Nord N20 5G] PsYk0n4uT:
Just another mission and a mistake that will hopefully keep someone else from making the same one lol
[OnePlus Nord N20 5G] PsYk0n4uT:
I have access to another device but it's not unlocked and not sure if I can use it to pull anything helpful
[OnePlus Nord N20 5G] PsYk0n4uT:
Actually wasn't even aware booting the image without flashing was even possible. Guess I still have a lot to learn. According to another member in the n10 threads.

Thanks for the tip though, Im sure that will be infinitely valuable in the future.

How would I go about trying to get twrp built for this? I know it's probably not simple. Can a device tree be made with the above posted backup for this purpose?
[OnePlus Nord N20 5G] PsYk0n4uT:
So when attempting to open in settings, STATUS, access IMEI etc..., It says this. I'm wondering if it's some sort of conflict from being still Sim locked? I ran the command via adb that has worked on other nord devices to OEM unlock with locked sim and then it rebooted, got the OnePlus loading animation instead of TMobile.

Also this message pops up over and over forcing me to reboot th phone, have tried clearing the data manually but it's obviously something outside of that. I'm wondering what would be different about your boot.ing than mine. Are you on the most recent update? Because I was not I don't think
[OnePlus Nord N20 5G] PsYk0n4uT:

[OnePlus Nord N20 5G] PsYk0n4uT:
Do you have any info about your sy...d a patched boot.img based on your boot image
[OnePlus Nord N20 5G] PsYk0n4uT:
Looking at the specs it looks like our phone may be the exact same phone as the nord ce 2 lite. Which would explain why OnePlus care detects the phone as such.

Could anyone verify this?
[OnePlus Nord N20 5G] PsYk0n4uT:
So looking at this from the N10, it seems that patching the boot.img with magisk is known to break radios:

https://xdaforums.com/t/flashing-gsi-roms-onto-your-nord-n10-5g.4294113/

Could you please post the unpatched boot.img? Want to try the unpatched boot.img and hope that fixes it. Not sure if it will. But hoping that it will.

Ok I got it fixed. Was given an unpatched boot.img and flashed that. Could not use fastboot boot boot.img but I took the risk and flashed it and all radios are back online. IMEI and everything is detected correctly

Lessons learned: be patient, don't mess with things unless you fully understand what your doing especially when someone who knows what their doing hasn't tested it out first,, boot images instead of flashing to test them out first(didn't even know you could do that but glad I know now). Sometimes it's worth a risk but def have to weigh the pros and cons. Flashing untested images is risky.
[OnePlus Nord N20 5G] PsYk0n4uT:
unpatched boot image worked for me with may security patch 1817 tmobile variant.

after flashing the patched boot.img i lost radios, flashed this unpatched and radios are working again here is the clean image:

Dumb questions, but I cannot get the N20 into download/fastboot mode. I booted to recovery, but no advanced options to enter fastboot mode. I tried power off, then power button + volume up, then power button + volume up & down together. I tried plugged in and unplugged. Any suggestions?? I've been rooting phones since smart phones have existed, but one confounds me.
[OnePlus Nord N20 5G] DrScrad:
you've tried adb reboot bootloader?
[OnePlus Nord N20 5G] PattasuBalu:
Try going to Fastboot by using adb
[OnePlus Nord N20 5G] dustinsmock20:
okay i really need some help.

it seems im having the same issue as some of you, i got the bootloader unlocked, and tried going through the process of rooting it. and then lost all radios. now im having the problem of not having the os to re install. i have the NordN205g rar file that people have been posting (the 12.1Gb one) but how do i actually put it onto my phone? no where can i find the steps to do so. some websites give me a whole command list i have to type in on the CMD prompt, but with that it wants a recovery.img which i dont have anywhere, as well as a few other things. and within that whole 12GB rar file, i cant find steps or any process as to putting it onto my phone. im going on day 4 of trying and ive never had my phone out of commision this long. if anything can someone make a video for youtube lol
[OnePlus Nord N20 5G] PsYk0n4uT:
easiest way is just use the super, and the radios i posted in other threads. wont be the newest security patch but atleast you will have a working rooted system. disable dm verity and verification since you will probably have mismatching system images

here is a july super. its not completely stock as system partitions have been set to RW but this along with the july modems and vbmeta disabling dm verity and verification should get you booting again

supersysRW.img

drive.google.com

if it doesnt work after flashing all that then join the telegram group and ask for a july vbmeta and use that to disable verity and verification
[OnePlus Nord N20 5G] dustinsmock20:
okay now how do i use the super exactly? im in the middle of downloading the file now, i just have no idea how to flash it or whatever
[OnePlus Nord N20 5G] dustinsmock20:
i tried flashing it to system and it says partition not found, sorry im so confused
[OnePlus Nord N20 5G] DrScrad:
Since he's having so much trouble, would it help if he just switched slots and flashed all the partitions (assuming they're on the same secuirty patch)?
[OnePlus Nord N20 5G] dustinsmock20:
do you know of the exact steps i should take on flashing the stuff? like im trying to figure this out. i found out i can flash that super file to the super partition. but im having issues on what to do with a lot of this stuff in the NordN205g.rar file. online it shows im supposed to flash all these things like the Abl.img, but the issue is, a lot of the .img files they want me to use, arent actually .img files in the rar, they are all .elf, .mbn, and pretty much anything except the .img files i need. i would go through changing them all to .img but im pretty sure that would just make them all unusable.

if i dont have any of those files, that means i only have 2-3 files i KNOW i can use, which is the supersysrw.img and the N20boot.img, i do have the july20Modems folder, but there are 2 different sets of modem files, the modem_a/b and Modemst1/2, and im not sure which im supposed to use, or if they are both used and places in diff partitions.

so it would just be helpfull to know a list of EXACTLY what files i should be using, what order i should flash or use them, and if im missing specific files, what those might be. whoever helps me through this, your a true miracle worker, i already cant express how thankful i am of this community
[OnePlus Nord N20 5G] PsYk0n4uT:
Yes that would probably be smart lol
[OnePlus Nord N20 5G] PsYk0n4uT:
To be honest you should be able to o flash either of the a or b modems to either slot just pick one and flash it to the slot your working on but make sure you flash the same all A or all B. You don't have to flash the A to slot A you can flash them to slot B just make sure you flash the same and if A modems don't work just try the B modems. Sorry for the confusion. One of them might be may patch and the other July patch since it was updated. If one set doesn't work just try the other to get your radios back. These were pulled from a device that had the same issue your having and had to be repaired so I probably didn't think to wipe the inactive slot down afterwards. Maybe that's a good thing for someone who may need May modems
[OnePlus Nord N20 5G] dustinsmock20:
what modems controll what? or does one modem controll all of it?
