Yes, the title sums up what I'm curious about.
Turns out I got an Xperia M2 Aqua with a broken display as a hand-me-down from a friend. I fixed it and it's working great! (check the pics if you'd like).
Spoiler: Pictures of the process

It's alive!
It works and looks great!
... except for the lack of proper LTE bands for my carrier, specifically bands 4 and 17. So yeah, it's currently stuck on 3G/HSPA, which is fine for chatting and checking email, but can be a bother for more intensive tasks.
I know there's another model of the M2 aqua which properly supports such bands: the D2406. Would cross-flashing the modem/baseband from that model do anything?
I actually thought about doing a motherboard swap but I would have to dumpster-dive the local phone repair market to get a motherboard from that specific model (or buy one online), and I can no longer justify the cost, time and effort haha.
I remember reading some LTE band unlocking tutorials for qcomm phones which used the USB diagnostics mode and QXDM or QPST for altering raw values. It seems very risky, that's why I'd rather ask if someone here has had a positive experience in this area, and if so, I'd ask for guidance or advice on the matter.
Any input is appreciated.
Thanks in advance!

That is the W8 model they reviewed. (Canada only model)
Would that have something to do with it? I don't keep up on all the bands/frequencies that all the carriers all over use.
I really was hoping the S6 would move away from all these region specific models since they are managing the radios on their soc with Broadcom now.
You almost have to buy an iPhone if you travel internationally a lot. I don't know of any other phone that has everything covered by the radio.

The Sony Z3 sold in Taiwan has most world bands on it of LTE.
Samsung and HTC suck at this. They should at least release an international model on their own website for those who do not mind forking out full price to get an unlocked model with most LTE Bands for those travel often.
Still just GSM though right?
I thought the iPhone covered much more than that. Maybe I'm wrong..
I just bought my RN7P, as soon as it turned on i connected succesfully to my 5Ghz wifi (Lower channels <48) after that phone asked mee to download update and in rush i agreed. It downloaded new ROM

After that it connected only to 2,4Ghz wifi. Curious about that issue i downladed band scanner to search for some 5G wifis and it detected only ones with 100+ channel. Turned out that its ROM related so after quite digging for info i learned about ARB, Bootloader etc.
So my RN7P have unlocked bootloader but "fastboot getvar anti" returns "anti: 1" so i need ROM with at least 1 arb. Pretty straight forward but after checking few ROMs (including same as installed) i could not find one with present arb, i looked for global and india versions (from xiaomifirmwareupdater.com , osdn.net/projects/xiaomifirmwareupdater/storage and xiaomi.eu) and all had no ARB present (checked that with miui_arb_checker python script) and at this point im so confused that i need someone smarter to explain it to me.
Does this script lies? or
"anti: 1" means it is disabled?
From where (or which version) can i download, to enable lower bands and have correct arb?
Is it a bug in software and will be patched sometime? (There is a lot of misinformation)
I kinda want to have lower channels of 5Ghz because all of my 4 routers can handle only that bands, also i did not check version before update which is irrevelant if i cant figure out whats wrong with that arb.
Thanks in advance for answer and sorry for my long and messy way of asking question :silly:
I am buying note 10 from someone who bought this from USA but didn't use it. (I want the snapdragon variant which is not sold in my country)

I watched a bunch of YouTube unboxing videos but none of them had the charger or headphones put in plastic bags so I got skeptical a little bit( 2nd photo)
Try download mode.

Check the IEMI number.
Step 1: You can dial *#06# on your phone to get your IMEI number. Also, you'll get it by going to Settings>About Device>Status.
Step 2: Once you get the IMEI, go to imei.info, input the number on the dialog box and hit Check
Step 3. The system will automatically phone's information. If it shows something else than what your phone is saying, it is likely to be a fake brand.

Does anyone know what this flex cable is for on the back of the Nvidia Shield LTE Tablet ? I broke mine by accident while opening the cover but everything seems to be working so far .
Please guys - I know this device is dated but someone here has to know what this is .

Thank you very much for responding . Today I had to go out and do stuff around town so I tried the LTE at a couple of different spots . I wasn't able to get 4g but could get 3g/ H/ H+ . Youtube played fine and didn't even buffer so I was getting a decent signal . It's interesting that you said this is the LTE antenna because I've never gotten the promised "LTE speeds " on this device . I know this is an old issue and lot's of Nvidia tablet owners researched and tried to fix this . My question to you is rather than replacing the OEM LTE antenna , do you think updating the antenna altogether would help resolve the LTE non connectivity issue that plagued this device ?

Hello A71 users,
My name is Kelly Bellis and this is my first post. Greetings from Ellsworth, Maine! I'm not writing code, but I do wade into what app developers wrangle with day-to-day as a technical illustrator, writer, user and tester.
About 8 months ago, a number of forum participants and early users of the Samsung Galaxy A71 5G reported no longer being able to utilize L5/E5a after a particular firmware update. Has anybody here ever discovered why the OEM turned off support for L5/E5a?
Has anybody discovered a way to turn L5/E5a back on? If so, were you able to discover any issues pointing to reason(s) why it was turned off in the first place; e.g., too much noise? Did it have anything to do with 1227.6 MHz being used instead of 1176.45 MHz?
Qualcomm boasts that their Snapdragon 765 is dual frequency, but when I contacted them asking why the SM-A716U was not dual frequency, they blew me off saying to contact the manufacturer, Samsung.
At 13:03 PM (UTC-4) Thursday, May 27, 2021 (VKB) - Posted on Samsung Community:
https://us.community.samsung.com/t5...NSS-Snapdragon-765-SM-716U/m-p/1853677#M46915
Almost immediately I started receiving nonsensical gibberish in private messaging spam before turning off my email notifications for private messaging.
I also prepared the attached illustration [Samsung Galaxy A71U6 PhaseCenterOffset and SensorEvent Origin.pdf] in case it might be helpful to any developers. On the second page of the PDF is the data from the example [gnss_log_antenna_info_2021_04_03_17_57_52.txt]
Tangentially, I've tried getting Google's developers (GnssLogger and GnssAnalysis) to help ferret things out as it applies in general to the smartphone's internal GNSS antennas: https://issuetracker.google.com/issues/188695837
Thank you for any reply.
Kind regards,
Kelly
