[Samsung Galaxy S8 Questions and Answers] TheMadScientist:
You can't post pics or links yet. Either 10 or 25 posts.

I always tell people first check imei. Make sure the device isn't black listed. If that's good. We need to make sure it's truly sim unlocked. If so. Then maybe need to flash your carriers csc

---------- Post added at 02:32 PM ---------- Previous post was at 02:30 PM ----------

I don't know how to flash the csc from other countries. Maybe try flashing the newest u1 bit 6 firmware. In the latest Odin
[Samsung Galaxy S8 Questions and Answers] idrissbravo:
i've checked my phone is "clean status" is not black listed it was working normally.

G950U1 ? U1 bit 6 firmware i will search to try thanks

im running the U1 version of the firmware for my phone and its been perfect. The U1 is the unbranded version, so no dumb boot animation anymore etc etc
[Samsung Galaxy S8 Questions and Answers] idrissbravo:
after flashing many csc (there is no for my country for 950U) it stucks in bootloop

I have no boot animation but there is sprint OMADM notification now
[Samsung Galaxy S8 Questions and Answers] TheMadScientist:
Yea since I'm in us I don't habe to mess with changing csc never had to. That's what it sounds like if he updated. It replaced the csc to. And don't know what to do with his sim. Unless his apn is gone and needs 're input

---------- Post added at 03:07 PM ---------- Previous post was at 03:05 PM ----------

I've seen guys flash other country csc files. I just don't know the method as I believe Odin will fail.
[Samsung Galaxy S8 Questions and Answers] Youdoofus:
since you would be technically changing carrier information with the Odin flash, yes, it should fail in stock Odin. But it will work in modded Odin.

---------- Post added at 03:07 PM ---------- Previous post was at 03:05 PM ----------

factory reset the phone.
[Samsung Galaxy S8 Questions and Answers] idrissbravo:
i downloaded the U1 6 firmware csc:xaa . I used the modded odin (odin 3b) i ve made a factory reset i tried to reflash csc the modded odin fails

Still bootloop
[Samsung Galaxy S8 Questions and Answers] Youdoofus:
try another cable, reboot your machine, get a new fresh download (dont go directly to sammobile.cim to get it, get the Frija tool or Samfirm, they take literally 1/5th the time to download the firmware sets), try a different computer, uninstall the drivers and let windows reinstall them when you connect your phone, is ADB installed system wide? if not, there is a small tool to do it for you
[Samsung Galaxy S8 Questions and Answers] idrissbravo:
NO THING of those done . i think erase NAND and re-input SN (that i didn't found) , IMEI and information (prod name, device type...) the repairer made a catastrophe. i installed phone info i can't imagin what i found all information are false.

can i set to zero and re-inter the information ?
[Samsung Galaxy S8 Questions and Answers] Youdoofus:
IMEI changing and that kind of stuff is sketchy. Can they reflash it for you?
[Samsung Galaxy S8 Questions and Answers] idrissbravo:
how those "they" we haven't samsung service , we have just some stores that sell phones and they can "repair" them :mad:

they says to me that they don't knows about american samsung (something that i love because of snapdragon)

thank you for all your effort to help me ;)
[Samsung Galaxy S8 Questions and Answers] TheMadScientist:
Nand erase does not wipe IMEI.

And rewriting isn't discussed on XDA
[Samsung Galaxy S8 Questions and Answers] Youdoofus:
the "they" is the repair shop you had work on it. its hard to know how to un-do what they did if we dont know what they did

i also cant imagine a repair shop that can work on Exynos S9s competently but not snapdragon ones

Hi there!

I'm a game developer. And we plan to promote our new game app in October. As a small studio, we do not have enough budget to spend on ads.

Do you have any suggestion to increase the download of the new app?

Thanks for your advice.
[Touch Dual, MDA Touch Plus ROM Development] jonburge:
Have read the sticky on Niki GPS problems, but the Neon (the one sold by Best Buy in the US) probably has some type of GPS for 911. Has anyone had a look at whether the Neon GPS can be activated?

I now use it as my primary device and all it is missing for me is gps (although vga would be good)
[Touch Dual, MDA Touch Plus ROM Development] NetrunnerAT:
Do you know the different, betwen A-GPS and GPS? 911-GPS Tracking is different.

[Miscellaneous Android Development] skeleton1911:
You have the F1play ? And Look into your flashtools settings. Are they by default?

And hold vol+ then plug in the cable ( after you pressed download button)

I tested it over 10times and it works.

I use flashtool v5.1916

[Miscellaneous Android Development] zironia:
I updated SPtools from 5.16 to 5.19. and it flashed. My IMEI are messed up though. Looks like you need latest SP flash tool for sure.
[Miscellaneous Android Development] skeleton1911:
But your imeis are not gone/messed up because you flashes my rom.

In flashtools never use format+download.

Only use download only option. Or if necessary firmware+download.

With format+download it will wipe the nvram and IMEI...

[Miscellaneous Android Development] zironia:
it gave an error that pim was out of date and said I had to use format and flash. I will fix the IMEI no big deal
[Miscellaneous Android Development] skeleton1911:
Next time use firmware upgrade + download when pim makes an error ;)

boot loop on Umidigi screen. Red State on screen with message Your device failed verification and may not work properly. Please download boot image with correct signature or disable secure boot. Your device will reboot in 5 seconds

---------- Post added at 05:22 PM ---------- Previous post was at 05:14 PM ----------

did I lock my bootloader again? not sure what secure boot is.
[Miscellaneous Android Development] skeleton1911:
If you choosed firmware+download in flashtool it might lock the bootloader again. Not sure about that.

But not a problem at all.

Press and hold vol+ and power together . When the screen boots up release power button but still hold vol+ . You will enter recovery then.

Make a reboot to bootloader and check if you are unlock or not.

Also you use twrp? You can ,but at the first flash you have to use stock recovery , otherwise it will be in red state.

Flash my rom.zip as it is . Should be working.

If you need help send me a private message. We can go via TeamViewer .

[Miscellaneous Android Development] zironia:
I used SP tool. I still get the boot loop when I flash your rom through sp tool. I have flashed back the factory rom and boot fine. I will make sure bootloader unlock is set in developer options. I have to go to work now so I will mess with it more later.
[Miscellaneous Android Development] skeleton1911:
ok thank you.

steps i did when i tested it:

i unlocked bootloader.

flashed the rom via flashtools ( first with firmware upgrade option) because the base was new.

after that i tested it over 10 times with "download only" and it worked fine.

let me know how it goes later for you.
[Miscellaneous Android Development] InTheY2K:
As I need my phone as a daily driver and I cannot afford to have it not working for a longer period of time, I am still hesitant... Especially because of the full wipe. :(

What's your recommended quickest way of restoring the status quo (i.e. apps and settings) after installing your ROM? I would love to make the move, especially to have TWRP on it, but I am dreading the whole process of setting up and downloading everything from scratch again. :( Would Titanium be an option?
[Miscellaneous Android Development] skeleton1911:
Flash it in flashtools . And don't mark userdata.

This would be like a dirty flash.

Otherwise copy the data/app folder with a root explorer to your sdcard and then to desktop

Gesendet von meinem F1 mit Tapatalk
[Miscellaneous Android Development] InTheY2K:
Sounds tempting. But that would be something of an in-between status. The data partition is still encrypted then, no? Which means one way or the other I would have to bite the bullet and wipe it. :confused:
[Miscellaneous Android Development] skeleton1911:
no. i didnt removed the encryption yet.

so its ok

i tested and edited many hours . but that fileencryption is

not

panic wait,check,quota,formattable,resize,[COLOR="Red"]fileencryption[/COLOR]=/dev/block/platform/bootdevice/by-name/userdata

its

panic wait,check,formattable,quota,resize,reservedsize=128m,[COLOR="red"]forcefdeorfbe[/COLOR]=/dev/block/platform/bootdevice/by-name/metadata

its a bit more complicated and also in boot.img..

so encryption is still there. :)
[Miscellaneous Android Development] InTheY2K:
Oh! I thought encryption and TWRP are mutually exclusive. :-o OK. I'm surprised.

[Miscellaneous Android Development] skeleton1911:

[Miscellaneous Android Development] alec.claire:
1. What recovery is included with this ROM?

2. Can it be flashed with TWRP or only SP Tools?

3. Does flashing it resent bootloader to locked state? If yes, can it be flashed without boot to keep the bootloader unlocked?

EDIT: self-reply

Ad. 1. No idea, flashed the only proper one just to be sure instead. https://xdaforums.com/android/development/recovery-twrp3-3-1-umidigi-f1-play-t4007315

Ad. 2. Only SP Tools. Bit shame. Only use "Download only".

Ad. 3. Flashed everything including boot - bootloader stayed unlocked happy to say. HOWEVER, you need to use "Download only". If you use "Firmware upgrade" the phone will loose the bootloader unlock and it will go into bootloop. If it does, reflash stock ROM using "Firmware upgrade". Then repeat bootloader unlocking procedure.

This is very important - DO NOT TRY TO UNLOCK BOOT VIA ADB while having Eragon installed on your phone. You will loose bootloader unlock (yes, when unlocking and confirming the unlock and phone showing successful unlock). Then phone will go into bootloop and you will have to flash the stock ROM and unlock the bootloader once again. You may also experience occasional boot but with prompt saying that some apk stopped working and frozen, unresponsive screen. After that you may try reflashing Eragon with SP Tools or if it doesn't work flash stock ROM and start unlocking bootloader once again.

Eragon when installed comes with pre-installed Magisk 19.3, Magisk Manager and unlocked bootloader. Do not touch OEM bootloader unlock or try messing with it via ADB. Magisk can only be updated via Magisk Manager (at least on my phone) via "Direct install". DO NOT try to install Magisk update via TWRP or the system will boot but with prompt saying that some apk stopped working and frozen, unresponsive screen. After that you may try reflashing Eragon with SP Tools or if it doesn't work flash stock ROM and start unlocking bootloader once again.

There is file manager called MiX, but you also can browse to SD card via Settings and install file manager apk of your choice.

[Miscellaneous Android Development] Fudgesiclesqq:
Hi, I've been following this thread for a couple of days now because my UMIDIGI F1 Play has a screen delay when I lower the screen brightness. I saw a youtube video and it says that I need to flash the firmware again in order to fix it.

My mom bought this out of an official online store, it's only been 2-3 months.

I read all of the thread and followed all of the procedures but now it won't turn on.

here's the procedures I've done: unlocked bootloader by turning it off then using a laptop, then flashed the original UMIDIGI ROM using spflashtool V5.2032 (firmware upgrade) and lastly flashed Eragon (download only).

I think, I've everything right although this is my first time using this method.

Can you point out the things I've done wrong.

(sorry for scuffed english)
[Miscellaneous Android Development] :
Did you make sure to wipe your Phone's data before flashing? "Dirty Flashing", which is when you do not wipe your Phone of its Data before flashing a ROM of any kind, Stock or Custom, can lead to many issues. Also: can you still load into the Bootloader or Recovery? If so: you can definitely save your Phone.
[Miscellaneous Android Development] skeleton1911:
Not yet. Twrp will work when you flash it separately after first boot. But encryption is still there.

My v1.0 has focus on performance and battery with a few more mods ..

Next is to get the encryption thing ....

(As said above, it seems to be a bit more difficult to remove it, so I have to investigate and code more..)

Gesendet von meinem F1 mit Tapatalk
[Miscellaneous Android Development] InTheY2K:
OK, still on stock ROM, I flashed TWRP with the official app. It can't do much (not even backup) because of the encryption. That's expected behavior, correct?

And with the Eragon ROM it will work like it's supposed to?

Gesendet von meinem F1 mit Tapatalk
[Miscellaneous Android Development] skeleton1911:
That behaviour is normal yes.

In my rom the encryption is the same like in stock ..

So there it will be the same behaviour.

As said above. I will try to remove encryption asap. In v2.0

Some Google Apps that are available in Playstore anyway. Like : Duo , Maps, YouTube , Kiosk, etc..

And some unnecessary System Apps Like : flashlight , Quick launcher etc..

Also there is many more in system added from me. Hardcoded..

Should we install/download everything to the phone? even the preloader.

Sorry if it's a noob questions but this is my first installation after like 7 years :(

Any tip before installing?
[Miscellaneous Android Development] skeleton1911:
Yes.

1. You need to unlock the bootloader.

(If you don't have it)

2. Install it like stock rom.

Means install mtk drivers to pc and flashtools.

Then extract the rom.zip and flash the full folder via flashtools.

Tip:

This based on the latest umidigi update , if you are not already on the latest September stock rom and after flashing the rom don't start , use the option "firmware upgrade " in flashtools.

The preloader etc all based on the latest....

[Miscellaneous Android Development] Aerozy:
1. You have a tutorial about how unlock the bootloader?

(I found https://xdaforums.com/showpost.php?p=79367004&postcount=4 but is not that clear)

2. My PC detect the phone when I connect it, so, I guess the drivers are properly installed.

Yah, the phone is updated to the latest version, V1.0_20190724_20190903-1850
[Miscellaneous Android Development] skeleton1911:
I don't have a tutorial bit it's easy

You need adb for it

1. Power off phone.

2. Hold vol+ and power together and release only power button when the phone turns on . But still hold vol+

3. Now you are in recovery mode.

(If you see a dead android icon. Just press vol+ and power short, then you enter recovery)

4. In recovery choose reboot bootloader.

5. Now connect the phone to pc and open a CMD to adb ( for me it is c:/adb )

6. Use this command.

Fastboot flashing unlock

7. Look at your phone and apply.

Done.

I conscious didn't made a tutorial for this and how to flash , because there are many of them here and on umidigi community..

[Miscellaneous Android Development] skeleton1911:
Or use adb when phone is on.

Enable usb debugging in developer settings.

And via adb use this command

I think I found an easier way to unlock the bootloader:

Steps to Unlock Bootloader on UMiDIGI F1 Play

1. First of all, Enable Developer Mode on the UMiDIGI F1 Play

2. Launch the Settings application

3. Scroll down and tap on the Developer Options option

4. Toggle the OEM Unlock option on

5. Confirm by tapping the enable option.

##

Now Imma install the ROM to test it :D
[Miscellaneous Android Development] skeleton1911:
Well . Yes enable the OEM ... In developer settings is also necessary. But it will not unlock the bootloader. It is need to enable that that you are able to unlock it. But it's still close .. you need to make that steps in adb.

Gesendet von meinem F1 mit Tapatalk
[Miscellaneous Android Development] Aerozy:
I think I'm doing something wrong,

The CMD keeps on:

C:\adb>Fastboot flashing unlock

< waiting for device >

The phone is already in FASTBOOT mode...
