I tried to follow these instructions: https://www.xda-developers.com/t-mobile-oneplus-7-pro-root-tutorial/
I first flashed the phone to the international firmware and then installed the devleoper preview which allowed me to unlock the bootloader.
I then updated the developer preview to a beta version of oxygen os 10 which made it possible for me to use the fastboot mode in order to load the twrp and then install it with sideload
I then tried a few custom roms such as havoc os.
Unfortunately at that point I get kind of stuck because there is no service, which is strange considering that the article claims that the service would become available during a custom rom install.
After flashing the phone back to the international firmware the service works again.
I am not exactly sure what I am doing wrong.
Basically the main issue has to do with the fact that there is no service as the developer preview trick starts and me not getting it back until I flash back the international firmware which has the bootloader locked and has no custom recovery.
The main reason why I wanted to do all of this is to simply have root.
The solution ended up consisting of reinstalling the stock oxygen os with the TWRP recovery AFTER the whole unlocking thing was finished, at which point it should either be possible to jailbreak the oxygen or to install a custom rom.
Either way the service seems to be back.
If you ever encounter such an issue it's possible that reflashing the stock os with TWRP may fix it.

Hello everyone.
I live in Brazil and I bought at the Aliexpress MI4C Xiaomi. I haven't received it yet, but I've already started researching ways to use it with another ROM than the original. The seller sends the device with google apps and multilanguage option. So, he makes some modification in the ROM, and says to not update the ROM officially on Xiaomi servers.
I see a lot of complaints about the Chinese bloatwares in ROM and so I wanted to install one that was good, but nothing with applications in Chinese or unnecessary ones.
My question is: in this case the bootloader is already unlocked?
In the meantime, I sent my request for unlocking bootloader to Xiaomi and received the SMS containing a link. As soon as I get the cellphone I intend to do the procedure. There is a risk of bricking the phone?
I’ll do appreciate good links with how-to and good ROM to daily use.
Thank you.
The seller shipping a modified ROM and telling you not to update the official would suggest your bootloader will not be locked. For now only flashing the latest official China dev builds will lock your bootloader.
Getting pre-approved for unlocking couldn't hurt though I guess.. just in case. You might need to have a working Xiaomi framework in your ROM to register your phone once though. If your ROM does not have the xiaomi services, I would suggest either Xiaomi.eu or sMiUI as a ROM, both are pretty much stock MIUI with some chinese bloat trimmed.
But most likely you will not need to unlock your bootloader anyway. You will need to check your bootloader through adb anyway before doing the steps to flashing a new ROM. You will best be flashing your recovery through adb, the instructions can be found through most ROM pages or simply searching TWRP Mi 4C. The command to check if it's unlocked is
Code:
fastboot oem device-info
A very extensive directory can be found in the INDEX thread, first in this forum.

you cannot check the bootloader locked or not by that way. My phone when checking this, gets the input "bootloader unlocked: false" but I can flash other recovery freely.
in his case, he is using a modified rom, it means his bootloader is not yet unlocked. Right now, if he wants to come back to chinese rom, he should use Mi flash to flash his phone. If he wants other rom like CM13, he should download the latest TWRP and the rom, put the rom into his phone storage. Then try to go to fastboot to flash the recovery, then go to the recovery and flash the rom.

Ah, that might be incorrectly reporting indeed. In any case when trying to flash recovery, if you're locked it'll simply fail and won't be harmful.
But why would you think his bootloader is not unlocked? If he's using a modified rom, it was probably flashed through fastboot or a custom recovery, both require the bootloader to be unlocked.
But even if he was not on a modified rom, stock Mi 4c have always come bootloader unlocked. Someone would have to have gone out of their way to lock the bootloader and I doubt any reseller would do that, they would risk a lot of refunds from angry customers.
I strongly advise against using miflash to flash any official rom unless you have no choice, since then there's a chance you WILL lock your bootloader. For now only dev builds are locking it, but the next stable release might very well too.
The first step should be to flash TWRP
The second step to stay away from Official China build
The third step to keep away from Official China build
The fourth st...
^ sorry my bad.... I was not focused. Actually I mean his bootloader is unlocked .
The safest way is flashing via computer, using mi flash or flash twrp image. You are right
1. Ur phone not lock bootloader
2. U can flash custom recovery...(TWRP)
3. "MUST" Stay away from official MIUI ROM
4. Flash whatever u want...sMiui, CM13, etc,etc
5. Remember Point No.3
***Btw, download official Fastboot ROM and keep it to ur drive, for just in case if u want to sell it again
Hello. Thank you all. I just received my phone. Great, btw. I'll read again and again all instructions and try. Thanks again!

Even as a last resort to getting your phone working if you did something wrong, please don't install the newer official roms, it's the mistake I did this weekend now I have a locked phone with a rom that has force-closes everywhere and absolutely no way back.

yes, or the safer way is always flash the latest chinese rom via miflash. twrp does not like Chinese roms

Don't flash the latest chinese rom.
No.
The only scenario where you would want to use miflash to flash a chinese rom would be as a last resort to flash the fastboot version of V7.1.6.0.LXKCNCK to restore your phone. Any later version will lock your bootloader.
If you don't care about locking your bootloader and the arduous process of unlocking it, you're easier off just taking all the latest updates OTA via the updater.
Hello everyone. Thanks for the help. In fact my bootloader was unlocked. I flashed twrp 3.0.0.3 and flashed the CM13 teamluminial, Android 6.0.1. Excellent. Thank you.
Hi!
Same scenario here..
I will receive Mi 4c with the Bootloader Unlocked, Rooted and the Multilanguage ROM.
But I have already received from Xiaomi after my request also the number for the official unlock procedure but now I'm a bit confused..
Do I have to unlock the bootloader once and for good with the official way?
Because I've read that the unofficial way isn't so secure in long term.
Do I have to install from the Updater the latest Cina Dev ROM and after that to proceed with the official unlock? Or it is better to use the Fastboot ROM?
Please could some one tell me in any case what to do ?
Thanks !
If you don't flash something that will lock your BL, no need to Unlock.
Ok first I must check the status of the bootloader to be sure that it is unlocked (via cmd control or cpu-z)
And after that can I choose an unofficial weekly miui.eu international ROM and install it?
Can I download and also update every week via Updater this ROM without issues?
At the moment my problem with flashing is that I don't have my pc (the one I have now runs win xp) and I don't want to stuck with the eventually malware or fully spammed modified rom of the reseller..
Which options do I have?

TWRP works perfectly. The backup is simply stored in your internal storage。
Okay so here's the info to the best of my knowledge,
Phone Model : Moto G 3rd Gen (XT1550, dual sim, 2gb RAM, 16gb ROM, India)
Bootloader Status : Unlocked
Root Status : Rooted
Recovery : Stock
ROM : Stock ROM 5.1.1
I've been running the stock Recovery & ROM with high hopes of getting an official OTA Marshamallow update.
To truly customize the device to my liking I flashed the xposed framework (the arm version) , it worked fine and all the modules I installed worked perfectly.
I also had Device Control, Xposed Gels, and some other apps to bring my Stock ROM experience close to that of Cyanogen MOD.
When the OTA Marshmallow update started rolling in , I was unable to install the update even after successfully downloading the file numerous times. But i was so comfortable with my device and all the customization I had on my device that I decided to keep using my customized Stock ROM.
4 months later (now) the lack of a gyro in this device and my eagerness to get into VR headsets has left me with no choice but to sell it and get another phone. So i needed it in a sale worthy condition, without the customization and with the Marshmallow update installed.
I uninstalled the xposed framework and all the modules but was still unable to install the OTA update.
So i figured i'd install CyanogenMOD with TWRP custom recovery.
I have done this for quiet a lot of my friends and am fairly used to the steps involved. I use the " minimalADB fastboot " kit and my device on fastboot to flash recovery. For some reason i was not able to flash the lastest TWRP image (twrp-osprey-3.0.0-r2.img ) for the device nor was i able to boot from it :crying:. The fastboot command prompt on my PC would show success but the devices would not restart into the custom recovery like it is supposed to, but the device would stay at the fastboot mode and kept restarting everytime i selected the recovery mode option.
I had an older image (twrp-osprey-2.8.7-r3.img ) which i couldn't flash either but i was able to boot into TWRP with this image. From here i tried installing the latest CM12.1 nightly available (cm-12.1-20160227-NIGHTLY-osprey.zip) as soon as i swiped the device would just reboot, i tried this numerous times and with other nightly builds as well.
In haste and frustration i wiped the cache/dalvik , internal storage and system through TWRP , thinking that changes made in the quest of customizing my device were causing this hindrance. I had no OS now. I went over trying to flash TWRP and CM12.1 many times again with the same issues.
I came about a thread on How to " Fastboot Flash Moto G (3rd Gen) Factory Firmware Images " (http://forum.xda-developers.com/2015-moto-g/general/guide-fastboot-flashing-factory-t3187750) & used this firmware image " Retail Asia | India (2GB) - XT1550_OSPREY_RETASIA_DS_2GB_6.0_MPI24.65-25_cid7 ". Still no progress.
The bootloader unlocked warning has come back (i flashed a stock MOTO logo there earlier) which keeps flashing on my screen again and again , no booting into OS or anything else. Not even an error. As if there is no OS installed.
I have gone about the procedure in the above thread a couple of times, with no success and the same problem.
Is there any reason why i'm unable to flash a custom recovery or ROM ??? What am i missing???
Please help i'm stuck, pulling my hair out with no phone and completely frustrated.
Thanks in advance.
Did you check your build no for stock ROM?

Nope. Too late for that now.
If you're asking in regard to the stock firmware I tried to flash, it didnt depend on the build number. Just the model number and the RAM.

try to flash stock rom from here http://forum.xda-developers.com/2015-moto-g/general/index-moto-g-factory-firmware-images-t3169639 but dont mistake this time double check your model with build number using carefuly the steps from here http://forum.xda-developers.com/2015-moto-g/general/index-moto-g-factory-firmware-images-t3169639
You will not brick the phone if you use the latest firmware and do a factory reset before flashing.
Good luck.
but do at your own risk i am not responsible for anything

the link provided is the exact same link from where I flashed a stock rom before.
build number for stock rom??? am i missing something???
all i see is the model variant (xt1550 is my phone)
RAM specification (mine is 2gb)
and the region (mine is retails asia | india )
so i went with the following firmware
Retail Asia | India (2GB) - XT1550_OSPREY_RETASIA_DS_2GB_6.0_MPI24.65-25_cid7
where does the build number come into the equation???
Please lemme know if im doing something wrong. Thanks for the replies.
So I've successfully flashed twrp-osprey-2.8.7-r3.img to my device and I've been able to boot into twrp. The touchscreen doesn't seem to respond though. It asks to swipe to begin and I'm stuck again.
I had the screen replaced a couple of days ago.
Could it be a faulty screen or a software issue?
P.S. I have not been able to flash any version of twrp after the above mentioned version (v 3.0.0 is the latest stable version) but the ones prior are flashable.

Is not big issue
Is it still possible to boot back into the OS? If it is, check if you have OEM unlocking enabled, since you're on stock ROM, it might be gotten unchecked after unlocking your bootloader because that's what happened with me. If you do t wether or not that was checked, you're at a dead end and there's nothing you can do. You can try paying someone to fix it, i.e., Motorola.
What can cause this? My friend got a Pixel with the not-newest firmware and could unlock BL & root, etc, and he is attempting to flash custom ROMs but getting the same result (in the title). Does anyone know why? It is happening reliably on first boot of each ROM flash.
You don't give us much information to troubleshoot with. However, there a good chance you didn't follow the OP of whatever rom you flashed. Go back and follow every step. My guess is you didn't reboot to bootloader AFTER flashing the rom followed by flashing the vendor image in recovery to the newly activated slot.
Could also be any number of other things: outdated fastboot, outdated twrp, wrong flashing order, who knows with this little info.
I came from android nougat on my galaxy s8+, however, I wanted to update to oreo, so I flashed it through odin with all the necessary firmware files. I configured it all once after. However, OEM Unlock is missing from the developer options. I've read that you have to wait 7 days for it to appear but I don't have the time to wait as I have some projects to deal with. I'm wondering if I can dirty flash an old rom over stock rom to enable oem unlock through odin since I can't flash through twrp . Once I get the regular rom loaded, I'm going to flash twrp and find a custom rom based off oreo instead. Would be great if someone knows any work around for this.

Did you get a valid answer? Tx
Hi, I'm having a lot of trouble trying to install a custom recovery. I had it working a couple months back but wanted to go with official again for dumb reasons and now i want to go back but it won't let me flash TWRP, i can't find a TWRP specifically for this version either. It's Android 10 with March security patch.
I hope someone can help me.
Thanks.
Please only create one thread per topic. I've removed the duplicate thread you started on this topic.
As far as your issue goes, I don't actually know much about Samsung specifics, but I believe that particular message means you haven't unlocked your bootloader. You'll need to do that before you can flash custom stuff.

actually Im also having the same problem even though i have unlocked my bootloader.. I had previously installed twrp and was trying custom os until one os (evolution x) for some bricked my phone and i had to flash the stock firmware and after that when i try to re-flash twrp through odin it is saying officail binary can be flashed.

Like I said, I'm not 100% on Samsung shenannigans, but have you checked to verify that you didn't lock the bootloader as a part of flashing the stock firmware?
OEM unlock toggle in Developer's Options
Hi ¡...
1. You have to reinstall via odin the latest version 9 (AP, BL...etc)
2. On reboot do the entire TWPR flashing process for android 9
The current problem is that there is no TWPR for android 10.
