[Samsung Galaxy S10+ Questions & Answers] sikodemon:
Does anyone know if Service Mode (aka band selection) is still accessible on the S10 or S10+. I've been trying all the old codes (*#2263# and *#2683662#) to try and open it but nothing seems to work any more.

Is there still a way to launch it, even if the dialer code doesn't?

Just wondering if Samsung have completely removed it. Hope not as this was a really useful feature on my S9.
[Samsung Galaxy S10+ Questions & Answers] Mohamad Gahed:
*#0011#

But I don't know how to change the band in it

If you can help it will be appreciated
[Samsung Galaxy S10+ Questions & Answers] billa:
*#0011# is only a signal status page, there's nothing you can change on there, you need to get into the engineering test menu in order to change anything, which unfortunately is not yet accessible on the S10 series.

The following is only for phones with a micro-USB port, nonetheless it makes an interesting way to enable the hidden diag menus.

Without root or having to flash it with any other CSC firmware, you can actually enable most diag codes (including RIL test codes like *#2263# band change, *#2683662 lab test mode, *#2766338378# engineering diag menu, etc) on pretty much any model/firmware/region by simply plugging in a test cable into the phone (the other end doesn't have to be plugged in anywhere, it's just the built in resistor which enables diag mode/FactoryMode).

It's important to follow the next steps exactly in this order: Open the dialer, exit the dialer with the Back key (not the Home button!), reopen the dialer and now it should accept most test codes.

These cheap test cables can be found on Ebay or AliExpress, just search for "Samsung 523K uart cable" or "Samsung 619K uart cable". Some come as a combo where you can simply switch the resistor values via a switch, but you must try both values, since only one or the other will work on certain models/firmwares/regions.

I've been using this method successfully for many years (currently on my Samsung S7 with the latest 2019 firmware), unfortunately these test cables are only available for micro-USB connectors, so it won't work on the newer USB-C phones even with an adapter (because it doesn't extend the resistor lines, only the data lines). If anyone finds a solution for USB-C, please post a message here.

[Samsung Galaxy S10+ Questions & Answers] kirkers:
Thanks for posting this advice! It's been 4 years since you posted. I think that USB-C UART test cables now exist.

Here is one listed as "USB TYPE C HIGH SPEED UART" (link). Would this work? And does this method REALLY work for Verizon branded phones? Even unlocking them doesn't seem to make any difference regarding secret menus and service codes.

The data manual for the cable listed above can be found here (link). There is no mention in it about "523K" or "619K", which you say are vital to this workaround doing what it needs to do to access secret codes and menus.

There is also a general brochure covering "USB Type C Serial Cables" (link) from the same manufacturer, "Connective Peripherals". There are options for "USB to RS232 (DB9)", "USB to RS232 (wire ended)", "USB Hi-Speed to MPSSE", "USB to TTL UART", "USB Hi-Speed to UART". Which one(s) of these would perform the workaround you propose?
[Samsung Galaxy S10+ Questions & Answers] billa:
The serial over USB adapter your have mentioned wouldn't work because it contains an FT232 converter chip and no breakout for CC1/CC2 configuration pins A5/B5 as shown in the Wiki below, which are needed to solder in a resistor between those pins and the ground.

USB-C - Wikipedia

en.wikipedia.org

A better solution is to use a real breakout plug which has all the pins clearly marked.

Here's a couple, and there are many others available online on Amazon and on Ebay.

Make sure that it has a breakout for the all important CC1/CC2 (A5/B5) pins.

https://www.amazon.com/Type-Male-Plug-Breakout-Board/dp/B09KZRN8CX

USB C 3.1 Socket Breakout Board

USB C 3.1 Socket Breakout Board from PMD Way with free delivery worldwide

pmdway.com

You could solder in a 523K resistors between CC1/A5 and ground, and 619K between CC2/B5 and ground, which allows picking the resistor value by simply flipping the plug for different devices. Note that USB-C is only using one side of the pins at a time, that's why you can have two different resistor values on a single dongle.

I have tested those resistor values on several Verizon phones with a micro-usb cable (S4/S5/S6/S7), and they all worked fine. However, not sure if it will work on usb-c devices, so you'll have to test it.

Don't forget the important dialer steps, otherwise it will not work. First close down all apps, plug in the resistor dongle, open then exit the dialer with the BACK button (not the home or task buttons!), then try some codes like *#2263# band selection, *#22745927 enable hidden menu, *#243203855# CSC change, *#2683662# lab test, and *#27663368378# diag menu. If it doesn't work, try flipping the resistor dongle, restart, and do the dialer steps again.

Unfortunately I'm too busy at this time to play around with this, but let me know and post your results here.
[Samsung Galaxy S10+ Questions & Answers] kirkers:
Thanx billa!

You are truly a DIY gearhead, sir! :whistle:

This is way beyond my capacities to accomplish.

However it may help someone more in your league to accomplish the workaround.

I've taken an easier path of buying on Swappa a non-Verizon, unlocked 2-year-old Samsung S21 5G (it began life as an ATT phone), and the reseller has completely reprovisioned it to U1 (factory unlocked) status, or so they claim. I will soon discover if it is true, and whether I can do things like use service codes to access service menus, etc.
[Samsung Galaxy S10+ Questions & Answers] billa:
It's really not that difficult to solder in a couple of resistors on the breakout plug I have suggested, the pins are clearly labeled.

I'm quite familiar with the U1 firmware, and hate to tell you that even those are locked when it comes to more advanced diag codes such as *#2263# band selection, *#22745927 enable hidden menu, *#243203855# CSC change, *#2683662# lab test, and *#27663368378# diag menu.

The diag codes depend on the type of sim card being used, with ATT you will likely not get any, with Tmobile at least the band selection menu.
[Asus Zenfone Max Pro M2 Questions & Answers] aromohit:
Guys

I am new to this forum , and I am stuck with all my data locked in the device. The data is very important to me. my device's screen suddenly turned blue and touch is also not responding.

Service centre people said that the touch and display is fine the problem is with motherboard so they will replace it and all my data will be deleted and I have very important data in my phone.

Usb debugging is on in my phone but I haven't authorized in pc/laptop therefore when I run adb command it shows me device but with "unauthorized" tag. Stock recovery mode does not support all adb commands like push pull.

Is there a way to recover my data? Any custom recovery method without need of touch screen. Also which does not violate my warranty as my phone is under warranty and I need my motherboard replaced?

Please guys

P.s : my phone connects to my home wifi network and receiving Calls and messages.

[Samsung Galaxy A50 Questions & Answers] RandomAJL:
Some apps like Amazon for example don't have an adaptive icon. Some launchers will try and make an adaptable icon out of a standard icon if the adaptable version isn't available.
[Samsung Galaxy A50 Questions & Answers] RvD-86:
you can change it with the app adapticons
[Samsung Galaxy A50 Questions & Answers] RandomAJL:
You can yes however this will only work in the launchers, (not system wide) unless you get an icon pack from the Samsung store. Soo, in recent apps, for example, the icon from adapticons won't work... Unless your rooted and use lawnchair launcher with quickswitch, in which case the icon will also be applied in recent apps.

Hi

My friend bought a used Mate 9 MHA-L29 but build number shows NRD90M test-keys. The phone is on Android 7 with EMUI 5.

Is there a way to know the firmware region to flash the correct one. He tried Firmware Finder app but it didn't recognize the phone

Thanks in advance.
[Huawei Mate 9 Questions & Answers] zgfg:
Try with Fastboot.

Install Minimal ADB and Fastbbot to PC (find on XDA).

Enable Settings/System/Developer Options (tap 7 times to Build number in Settings/System/About).

In Developer options enable (in that order)

- Allow ADB debugging in charge only mode

- USB debugging

Connect to PC (wait to install drivers if needed), confirm PC key on the phone screen, run Minimal adb and fastboot

Run the following commands (you can copy commands to *.bat file and run that batch file in Minimal adb and fastboot window):

adb devices
PAUSE
adb reboot-bootloader
PAUSE
fastboot devices
PAUSE
fastboot oem get-bootinfo

The phone is on C900 region, will it be sim locked if I flash the C900 firmware? The phone is from Europe but we live in Africa.

And is it possible to rebrand to C432 firmware without unlocking bootloader?
[Huawei Mate 9 Questions & Answers] zgfg:
C900 is some global cust, it must not lock the SIM (to which provider to lock the SIM if that is global cust?) but let someone with c900 confirm about

You cannot rebrand without unlocking Bootloader - rebranding requires flashing and flashing is blocked with the Bootloader locked
[Huawei Mate 9 Questions & Answers] Haroun:
Thanks for the answer

It's true that it says the region is C900 but in the same time the sticker on the phone box says EU which should mean C432, also i've read here on xda that if u flash for example C185 firmware on a C432 phone it will result in C900 and no OTAs.

His vendor information say this Vendor: hw country: normal

So i'm a bit suspicious.

Also even dload method won't work if he try to flash stock firmware with locked bootloader?
[Huawei Mate 9 Questions & Answers] Haroun:
Btw he didn't use ur method to verify the region, he sent me a screenshot of version info which says: CVersion:C900 DVersion:Cust so i assumed the region is global.
[Huawei Mate 9 Questions & Answers] zgfg:
Any flashing by fastboot requires unlocked bootloader, dload does not require

But flashing by dload another cust may results in brick, or in the 'better' case with test keys (like you have)

What is written on the box corresponds to which firmware (cust) was originally installed by Huawei.

Once the phone was rebranded (that is why rehranding does) you can forget what the phone was originally, then the phone has new vendor, oeminfo - this is why I asked you to check by fastboot what the phone declares about its current/last firmware (it can be read even on the bricked phones if they can boot to fastboot, and then it can help for unbricking)

Project menu, Vendor hw means that SIM is not locked, it's not about firmware cust
[Huawei Mate 9 Questions & Answers] Haroun:
Everything is clear now, i'll ask him to check by fastboot, the phone is used and don't know what the original user did to it.

I see C652, I can't find a firmware for it? Is that the correct region

Or is there another way to fix it? He is on android 7 now.
[Huawei Mate 9 Questions & Answers] zgfg:
Im a bit suspicious about "NOT secboot recovery image!" but this must be all about the improper flashing resulting also with Test-keys

Use Firmware Fonder (install from Playstore) and choose Add Model and enter MHA-L29c652 (see screenshot)

However, your b109 (Nougat) is old, I cannot see there any firmware older than b158 Pie 9.01

You are (your friend) lucky - with Nougat you can instantly and only for 4-5 $ buy the Bootloader key - when contacting them, emphasize that phone is still on Nougat MHA-L29c652b109:

https://ministryofsolutions.com/paid-services/amp

https://www.dc-unlocker.com/

Actually, you can also (up to 20 $ or so) ask them for help/tools to install proper firmware, to get rid of Test-keys

Once you upgrade to Oreo (EMUI 8, Security patch Mar 2018 or newer) or even Pie (EMUI 9), obtaining Bootloader code is much more costly (45+ $) and you need to wait for a month or more.

However, BL code is unique for the lifetime of the phone and you can always (re)use it for relocking/unlocking no matter if you rebrand, upgrade, etc

Once you will have the BL code, you can follow the guides on this XDA Mate 9 subforum to rebrand to c432 and upgrade to the latest Pie 9.01 or even 9.1 (although, you can also read on this subforum that video stabilization and night photos were much better with Nougat and Oreo; to the other side, battery longs laster with Oreo or Pie, there are also other differences pro & contra)
[Huawei Mate 9 Questions & Answers] Haroun:
Thanks a lot my friend

I searched on xda and found that C652 can mean demo firmware, maybe the original user tried to flash C432 firmware which resulted in test-keys.

So basically DC unlock will generate the bootloader code and then rebrand to C432 region. I'll ask him to take it to a repair store for the code since we don't live in the same city. And assist him with the rebrand.

Thanks again my friend
[Huawei Mate 9 Questions & Answers] zgfg:
With DC, you need to buy credits in advance - so ask them and discuss with them if you/your friend want only the BL code or also 'unbricking' from Test-keys (you can give them Fastboot results and make a screenshot from Settings/About), and/or rebranding to c432

Then you don't need Huawei repair shop (?), and with DC you only communicate online, they provide you tools and assist

If taking Ministry, they want to remote connect to your PC by TeamViewer to do themselves (they are also little cheaper) - present them also Fastboot queries and About screenshot
[Huawei Mate 9 Questions & Answers] Haroun:
