Null IMEI/Baseband

Hey guys, so I'm pretty new to all this, I wanted to root my Galaxy S6 - SM-G920F - to be able to play pokemon from home... yes, that sad. So I started reading XDA like my brother recommended and "learnt" how to root my phone. In the beggining when i was installing SuperSU I had some problems and my phone went into bootloop, but it was because of my cable, I then reflashed it with another cable and it fixed the bootloop issue. I went on to install TWRP and that's when mistakes started happening. First of all, I forgot to back up my phone, including the EFS which, after reading countless posts, I understood is what gives the phone the IMEI code.
I tried installing the standard Xposed on Galaxy S6 (only later on i learnt you must use Wanam on samsungs from S6 and above) and my phone went into bootloop, with out knowing what to do (i tried the uninstall zip but it was failing to install from twrp...), very stupidly, i deleted my System folder... After much more reading, i tried using KIES3 and Smart switch to recover, but they always ask for the stupid recovery code,which I don't have, when i tried the upgrade and initialization option... I tried costum roms and a ****load of stuff. Custom Roms would usually work, my phone would turn on and that's when i noticed my SIM wasn't beeing recognized. (later on i also found out i didn't have IMEI) tried flashing the appropriate MODEM for my galaxy but it all failed. I don't remenber all the stuff I did tbh... I tried the tyrannus ROM and XtreStoLite Universal Deodexed Mod Edition ROM, and tried flashing the MODEM that comes with the last mentioned ROM and yeah, probably just useless attempts that wouldn't fix the problem in the first place. Then i tried flashing Stock, from Sammobile: I bought my phone at the Portuguese vodafone, so G920FXXS3DPF5_G920FVFG3DPC1_TCL (marshmallow) with Odin but it would always fail. Then i read something about splitting the folder in 5 and flashing 1 by 1 and it would work until the Hidden zip, which would always fail. I tried not flashing Hidden and my phone turned on and I went back to stock although, still with out IMEI or baseband. Then after more reading, i found out the best solution would be giving it to a store.
So i just rooted, twrp and did what i wanted to do in the first place. With the correct Wanam Xposed this time (later on i found a way to hack pokemon with out root... sucks :v) and i managed this time.
Yesterday i went to the stored and today the guy told me to go get it, with high hopes i went there, to find out he couldn't fix the problem... He tried Octobox to rewrite the IMEI from the one in the back of phone, but he says it failed. So now I really don't know what to do. The guy went on holidays and told me to go back there when he comes back, we wants to try to downgrade to lollipop and try to fix it from there (he said he has more tools available to work with). It could work, Galaxy S6 just got marshmallow 1/2 months ago officially, and i bought the phone in october of last year, so maybe with the ROM it came with, I really don't know.
At this point I'm just looking for suggestions. I'll be paying attention to the forum and try to reply to all the questions you might have to my best. Thank you all for your time and patience!
:EDIT: so... another major mistake i guess, I found out today, by asking my parents where they got the phone, that the phone wasn't actually purchased in vodafone, the phone was bought in a Samsung store, so it is unblocked. So most likely I've been flashing the wrong stock rom all along. Could you guys guide me in the right direction from here?

What would be the appropriate ROM for the unblocked? vodafone portugal is TCL, optimus is OPT and MEO is MEO. There is another one under the name TPH, would that be the appropriate one?

Solved
Okay... using the correct stock rom fixed all my problems... sorry for wasting your time guys! TPH was the right one

Where did you find your roms?

[Completed] Need to Flash ROM to Xiaomi Mi5. Every time I get freezing issues

Hello. This looks like the place I can get the best help.
Got a Xiaomi Mi5 last week - cheap and very cheerful. Having read online about possible fake roms and bloatware I thought the safest option would be to load the official stable rom to be safe.
Attempt 1
Following the MIUI guidance I downloaded the ROM, copied it to my phone in Windows explorer and then used the MIUI updater tool within the phone to load the new ROM.
http://en.miui.com/a-232.html
Everything went swimmingly for a couple of hours, but then the phone began crashing.
Attempt 2
By this stage I realised the above method was no longer available to me. So I got unlocking privalidges, unlocked my phone. Then, using MiFlash I flashed the latest ROM to the phone. Now the crashing problems happen within about a minute. It actually froze the screen first time round so I did it again.
Added fun issue - left my phone on overnight to charge. And it had stopped charging at 58%.
Attempt 3
Downloaded the EU MIUI Rom. Accessed TWRP in my phone and tried to use it to wipe and install. Not sure the wipes were fully effective - got a lot of red writing. And when I went to install the new ROM the internal storage was 0MB.
Had a look at guidance, and I forget what I did, but was finally able to see the zip file on my phone through TWRP. I got the "7" error. Have read how to fix this but seems too risky considering whats gone before.
Desired solution
I would just like any ROM on my phone which works. Don't really care which, I have followed each guide religiously. It may well just be a faulty phone but I don't want to send it back to China without ruling out the problem being me screwing with the software. Especially as I assume i've technically voided warranty... (I can reload Global Developer and relock it though so have hidden it pretty well. Only difference I can tell is that I now get a menu in recovery mode when before I got instruction to go to PCsuite).
Also - I seem to remember there originally being a downloaded_rom file in the internal memory which is no longer there. If im sending it back do I need to recreate one to hide my activity?
Appreciate any advice.

Greetings and welcome to assist. Xiaomi phones are encrypted by default so you need to wipe your phone in fastboot to access your storage again and you also need to flash latest su zip to disable dm verity. That should clear you internal memory issues and allow you to flash a zip through twrp
Good Luck

Has Anyone Gotten a Custom ROM onto a BLN-L24 (US Variant)?

I have tried quite a few ROMs, and all ended up going back to stock firmware because they wouldn't boot. I know I have to format data, and some ROMs ask you to change the data partition as f2fs.
Still, I think that there may be no ROMs that currently work for the US variant. One guy said LOS 13 worked, but when I flashed it, it failed. If someone has gotten it to work, can you please post as many steps as you remember on how to get it work?

Debrand to BLN-L21 following this guide and you're ready to flash cooked ROMs https://forum.xda-developers.com/honor-6x/how-to/guide-successful-debranding-to-bln-t3701050

Thanks, but wouldn't there be more issues down the line with a debranded phone? What if I soft-bricked my phone, it seems like it'd be really hard to restore? Has anyone actually ever done this on a BLN-L24?

Hello all,
I too am having issues with flashing roms to this device, US variant (BLN-L24). In my particular case, the rom boots up (EliteRom v7.1) and will actually function. However, wifi does not work, as well as I have no sound whatsoever. Youtube also will not play, nor will any videos, which I'm guessing is tied to whatever issue is with the sound. I have flashed multiple times per the step by step instructions, as well as following the Youtube video, all with the same result over the last few days. At this point, my phone is effectively useless to me, though cellular data does still work, just no calls can be answered. Anyone have any suggestions I might be able to follow? Also, even my TWRP backup that I made before installing the rom will not restore at this point. Any help is appreciated, thanks.

You must be missing a step or something, because [Elite ROM][EMUI 5.1] Elite ROM v7.1 for Honor 6X by HassanMirza01 works on the L24 us variant without issues, I have none.
Perhaps go back to stock and start over. I haven't had any issues with his rom and I didn't do anything more than what's needed to root/install twrp and flash the rom per his instructions.

I just followed the instructions; I believe to the best I could, and I'm stuck in a bootloop now. Which version of EMUI were you on before flashing? I was on EMUI 5.0 which may be my issue.
I started from EMUI 5.0
Unlocked my bootloader
Let it factory reset
Installed the Elite TWRP on the page
Booted to Elite TWRP
Formatted all partitions excpet for external sd card
Reformatted Data to f2fs
Re-wiped data
Checked that it was f2fs
Installed Elite ROM zip
Installed open gapps 7.0 ARM64
Installed the patch
Rebooted
Bootloop

On one of the attempts that I did for installing, I installed the patch and it put me in a boot loop. Maybe not installing the patch can help you?

I cant get anything to work for the US version. Sure stuff boots but some of it is just broken. On octOS i am unable to use root unless i switch supersu to automatically grant root to apps. I cant get root access by using prompt because nothing pops up. On crdroid i have the same exact issue. Id rather have the prompt than allow any app root access without my knowledge. With ELITE ROM my first boot brings up a home screen with no keyboard. It completely skips any kind of setup screen. I can get the setup screen by flashing a keyboard from an aroma gapps installer but then i lose google services. The US version also seems to be forgotten as for most roms you wont see it anywhere under supported lists.

I've never been able to get a custom rom to work on my BLN-L24. Everything just ends in a never-ending bootloop of frustration.
Though, I have only ever tried with EMUI 5.0+. Maybe an earlier version of EMUI gets better results...?

It really sucks that nothing seems to work. Ive tried flashing using multiple recoveries and ive tried all kinds of flashing to fix issues with the ROMS. Nothing helps. If anyone has successfully gotten a ROM fully working on BLN-L24 they need to tell people exactly what they did step by step.

It seems that for the roms located here, they seem to all assume that the phone has been debranded to bln-l21 variant. I don't know if it has any bearing on the current issues we're all experiencing, but I did notice that all twrps available for this device on the forums state they are the "Open Kirin Edition". It's been a while since I've rooted or rom'd a phone besides this one, but I've never encountered a twrp with a custom name like that.
I know that the developer of the EliteRom had his custom twrp, but is there a different twrp besides that one that does not state it is an "Open Kirin Edition"? Like I said, not sure if it has any bearing on things here, but I've been very confused about that.

For most phone i've ever owned you never had to change the recovery for each ROM. Its confusing. Most recoverys say Open Kirin Edition when booting. What confuses me is why we need to debrand to get the ROMS to work. If the phone pretty much run on the same hardware then why is L24 having so many issues? Why are the devs not testing on these devices?

Right, that's what I was thinking. For any phone I've ever rom'd, there was always just one twrp that everyone worked from.
Edit: found this while looking through the roll back to stock forum. I don't know if it will help anyone else, but figured I'd put it here as well if it might. All credit for this goes to the original poster johnnyrichter:

Tried this method after being on LineageOS for a week or two and having poor LTE signal, no MMS, and voicemail issues so I'm trying to go back to stock so I can have a fully functional phone since I rely on it heavily for work. Followed all steps using BLN-L24 B360 firmware. On step 10 I rebooted to update and it went right to "5% Installing Update" and stuck there for 5 mins, then rebooted itself, has been sitting at "honor" boot screen for 14 minutes so I made it reboot to EMUI recovery, wiped/factory reset, rebooted, loaded EMUI afte 2 more minutes. Appears to have worked and hopefully my issues are fixed!
Edit: Signal, mms, and voicemail issues fixed.

Hopefully will benefit someone here as well.

When debranding the BLN-L24, and branding it to BLN-L21, are there any issues with the ROMs once they're installed? I imagine the radios, and such are different for the two models??

Devs can only test devices they have in possession. If they don't have your phone model, how are they going to test it?

well, many don't want to give them a phone because most developers here tend to stop work on a ROM and leave people hanging.

I have gotten several ROMs working on L24 variant...
Yes it seems to me any Elite kernel based ROM works or should work on the L24. But /data must be ext4 format. Then even that the ROM works, the fingerprint scanner never allows a complete successful scan. I think because it must be f2fs format for that encryption to work or something. This is the link to those ROMS https://hassanmirza01.blogspot.com/p/custom-roms.html?m=1
On the other hand the LOS based ROMs never work or at least they reboot and the screen is always black or the ROM branding just stays there flashing. This sucks cause I want to run the newest Resurrection ROM but I ask the developer about why I have that problem or how long that ROM takes to boot and I never get an answer. He also just put a new beta AOKP ROM up and it does the same black screen thing too.
I am also suspicious it has to do with the version of TWRP. I think some are capable of formatting f2fs correctly or the encryption or whatever. Point is some of the devs need to be a little more consistent answering questions at a minimum. I know it takes time to fix bugs but give us a little heads up.

differents problems with my j7...

Good morning, I've been on the phone for two days now that's crazy ... and everything is clear to touch where I should not surely hehe
I comment a little to see if you can throw me a handle, either to put the phone right or neck.
I had a rom on my cell phone for maybe 4 or 5 months and the only thing that a couple of weeks or so ago every time I went in the car or with the bike when using bluetooth calls failed, so I started looking in internet and I saw that many rom failed in that, because I decided to put another rom. All good, but the same mistake followed and the one that did not vibrate added up. Well now I have been trying to try different but yesterday there is no way, you can see that I made a small brick. After talking for some comments on YouTube, he told me that it could be that he has damaged binary, (I do not know what it is), they told me to download to Android 6.0
The question is yes, I tried a firmware (the only one that I could install with odin, the rest always fails) and I have now the phone that works half, because it still does not vibrate, every time I turn on I have to enter key wifi and some more things , not counting the andorid that I have haha ​​that is outdated.
Testing with Odin to install other firmware now I get on the mobile, secure check fail bootloader. (I understand that it may be that the bootloader is blocked) but I do not know how to unblock it either, I have the developer options enabled with debugging usb and OEM.
I have also tried to install with Odin the TWRP and it comes out that if it has been installed correctly but then I try to get in and out fail and restart.
I have seen that there is a guide here for TWRP but it is for android 7.0 ... so I do not think it's good either.
After this billet ... does anyone give me a hand?
Thank you very much in advance!
PD: I add, right now I have the J710FXXU5BRC3 version but J710FXXS3AQG1 runs too. both with android 6.0
PD2: another mistake, is that when I go to flash it puts: sw rec. check fail. device 5, binary 3

SIM Unlocked G920W8, 9.0 and 10.0 ROMs no longer detect SIM.

*SOLVED: see reply*
The ROM I used before was LineageOS [10.0] and used a custom ROM with Android 9 before that. Needed to unlock my phone, and couldn't do that on Lineage, and had troubles flashing firmware with Odin, so I ended up using FrankensteinS6. The Stock kernel seems to let me input the NCK, and unlock the phone. So that's luckily finally over.
For about 4 days now I've been formatting phone and trying again and again. FrankensteinS6 works, some other 6.0/7.0 ROMs work. But LineageOS now enters a bootloop, and Pixel Experience (9.0 and 10.0) and Evolution X 10.0 don't detect the SIM. The ones that don't detect SIM also show no IMEI, which was worrying at first because I though I lost a partition.
Possibly related, the ROM of Pixel Experience Android 10.0 for G920W8 will not install because (paraphrasing) "This device is zeroflte, this file is for zerofltecan, zeroflte***, zeroflte***" claiming that my phone isn't one of those models. I got this S6 from Bell Canada, and I still have even the sticker that says it is a G920W8, not G920F. However, the Pixel Experience ROM for G920F flashes fine (sans the main problem).
I don't know the exact LineageOS ROM I used before, but I've tried all of their 10.0 releases, tried redownloading, and I get the bootloop every time. I see some info online of flashing modem firmware, but... I don't even know where to start with that. As I mentioned at the start, Odin is crapping out. I couldn't flash firmware with it, because it would reject the phone right after I started flashing. Anything I could do within TWRP would be great. I moved it back to FrankensteinS6 for my sanity, I started doing this Sunday and I'm starting to repeat steps over and over hoping that it just solves itself.
I tried to keep this straightforward, and I'm sure I did a bad job. I can extrapolate on what I have attempted. Please tell me what I have to do to get an android 10 ROM working on this old beauty again.

I do not have all the solutions. As per my tests with my SM-G920W8. I have managed to find ROMS and try them out. I have only seen Nougat 7.0 ROMS to work almost flawlessly. NOT 7.1.2, important, 7.0 only.
I have also tested some Pie and v10 ROMS like Pixel Experience. The ROMS boot nicely but since I do not use a SIM card to call as I use SIP phone numbers and require WiFi. But that left asside, I came upon serious camera issues no matter what I try. Up to now, SamStock ROM is pretty much the best Stock ROM I found but I always need to run the Magisk UNINSTALLER before re-installing the latest Magisk version..
As for Kernels, well, Anything that is oriented with Lineage OS, I've had camera issues even with Nougat v7.0. So basically, the only ROMS I found good, as of today, for now, are stock ROMS v7.0. But, to do your tests, Even if you have a 920F ROM, you can download a 920W8 kernel as long as you download a kernel which supports your installed Android version. Also make sure to download the proper Stock or AOSP kernel (AOSP for LineageOS). There's not many but there's a few ones that work properly.
Another option is to download an AOSP ROM that works for W8 phones, unzip the file and grab the boot file inside corresponding to the W8 or T-Mobile version. You simply unzip your real ROM you want top install, replace the boot file for the one you got and rezip it. This made my phone boot properly for some F version ROMS but again, not without issues. That's why, I really suggest v7.0 Srock ROMS. I hope this helps you a bit. Again, you can have your own tests and other users may have other answers, but this is based off over 30 bootloops in my case of trying to mod a ROM for the W8 model. It's not easy to find a good one for Canada, I admit!!!

I flashed TWRP years ago, and I found out that I had a G920F version flashed. I don't know why Lineage allowed me to use SIM before, but rectifying this issue seems to made the SIM work in newer versions.
I don't know what the S6's predisposition to having crashing cameras is, but I have avoided this in the past by using custom camera apps, like Open Camera. This has saved me every time.
As for the boot loops... I think another thing that helped is that "format data" doesn't wipe the OS. When you are in recovery, having issues with bootloops in various ROMs, try advanced wipe, and wipe the system. It didn't fix right away, but the time I got Pixel Experience 10 up and running that was the trick.
