SAMSUG S20 ULTRA AFTER I CHANGED THE ROM! PLS HELP! - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

I have one problem with one s20 ultra 5g ... after firmware uptade from 10 to 11 ...
I bought the phone from a pawn shop and I had a custom firmware installed
I couldn't install many applications and that's why I wanted an original firmware
at phone status I get custom
now I have official android 11 but no signal
is my network blocked? or? I can enter the pin code ... but it doesn't take a signal ...
MODEL NAME SM-G988B/DS
BEFORE CHANGE SM-G988B only. meybe here is the problem ??
someone said it was a roted phone after seeing the phone in download mode
I don't know what that means and how it can be fixed !
Another thing I noticed ... on the back of my phone is written live demo unit not for sale
only now I saw this .... after 3 months from buying the phone

What carrier sim are you using. Big risk buying from pawn shop, you never know what you are getting. Since demo unit it could have been a stolen phone. So many good re-sale options other than pawn shop.

i use telekom mobile romania

If this is a Live Demo Unit it does not have any cellular functions. You will not be able to get any signal - sorry.

N930X - Is this an actual regional variant of Note 7 or used only for display models?

I'm currently browsing in Qatar and keep seeing N930X as the model number for the displayed Note 7s in various different shops - Is this the Middle-East regional variant or is the "X" part of model number just used for display handsets??
What model number does your Note 7 have if you have purchased it in the Middle-East? Is it Dual-SIM??
dubai - n930fd
I live in mexico, and the displayed units have that 930x too, the model sold here is 930F, so, I think that the "X" indicates a demo unit
Philippines, X is also the display unit and FD is sold here.
Finland, N930X is the unit in the stores and N930F being sold.
Thanks people - so to confirm, N930X = a demo unit model number.
I managed to check the retail box today (...should have done it before posting this thread, duh!) - I can confirm that in Qatar it is N930FD (dual-SIM).
Now to decide if I should go for it or still stick to my Note5 for now in the unlikely hope of custom ROMs to extend its appeal-life......
man, if you found some help, do not forget the thanks button
I need help putting another n930 variant on n930x

Only way to make it work like a phone is to change the mainboard. The X models are demo unit with all the functions except cellular.

Dubai note 7 recall?? HELP

Alright... So basically... I was on holidays in Dubai over the last few weeks. And, over there, I was lucky enough to buy a note 7 SM-N930FD, from an official Samsung store. I had bought the phone on the 28th of august.. before the recall. Now I'm back home, in the UK, reading about the note 7 recall and have absolutely no idea how to proceed. I don't want to send my note 7 back to Dubai because I'll have no phone in the meantime and it just seems like a lengthy process. Is there a way that I can maybe get my device exchanged here in the UK? Or what are my other options?

Samsung UK are being pressed to replace the handsets with local variants. If you don't mind a UK variant you should have no problems. (Initially Samsung refused to swap at all!)
A few have said that Samsung service providers are exploring swapping out for the same model but I can't see that working. Most companies of the world only swap out a device for the local variant available in the country you're doing the exchange.
contact Samsung is your best bet......
accept the local variant, thats all
The fastest way is to directly contact a Samsung
Its easy tho, I purchased note 7 from Kuwait now I am in India (my home country). Here, Samsung delayed sale of note 7 that means till now no official launch of note 7 nor they have started any recall (obvious, they haven't sell single note 7 here). Now my question is how should I go for replacement? Help

Thanks, fortunately one of my friend went Kuwait today so I send my phone with him. :victory:
Got a call from Samsung UK. Basically stated they can swap the dual sim phone for the one sold in europe so single sim - coral blue or black.
Asked about getting the dual sim as replacement and they said I would have to sort it out with the region the phone is bought from - so Qatar in my case.
Might just get the UK version with its two year warranty

Galaxy s9 live demo

Hello Experts,
I have messed up I need some expert advice. I just bought an S9 live demo. I tried to installed stock filmware and now it is not working. It says installed unauthorized software and now it is not working please someone help me. How can I fix this issue.
How did you buy a live demo phone? Many times these phones don't even have all the hardware like the modem or antennas, plus many are stolen. You can't get support here for a possible stolen unit.
You can get demo units of phones in certain countries and online. I think they can be made to work as retail units. I don't know how.
If it's anything like the S7, there is no Modem in the demo units, and the Fingerprint reader didn't work
So no way to make calls or texts
You could however just flash the F firmware to them to remove the limits of the demo firmware iirc
did the sim card work?
here in Cyprus, they are using normal phones with the stock rom! and if there is no availability the offer you the demo mode(which is a normal phone 100% fully working) at lower price and beter warranty(from store)
try your luck by talking to the person you bought it or from Samsung directly!

Mi Mix 2 Imei change (unlocked bootloader)

Hi everyone.
i got my mi mix 2 one week back from spain it is working fine on both sims but in my country now there is rule to approve all the imported mobiles through an imei authentication system (for custom duty). all the mobiles imeis which are not approved by that system will be get blocked in near future so my device will become useless. As i tried to approve through that system but they are demanding too much money for which i could have buy a new phone (300 US dollars). so i have my bar phone which is dual sim and is approved by that system as i purchased that from here in my country.
my question is that whether is it possible that i can shift that bar phone's imeis which is useless for me (kept in the cupboard for 1.5 years) into this mi mix 2 for good . because i am not using that bar phone, i will be permanently using this mi mix 2.
I am little bit aware of this rom flashing things as i recently unlocked my bootloader and got my 2nd sim working (as vodafone spain allow only one sim in mi mix 2) through edl mode and flashed the global version.
I am running miui 10.2.2 with UNLOCKED bootloader.
Kindly help.....
wtf, which country do you live in?
Pakistan

The only phone which had this feature I know of, is LG V20.
You cannot change IMEI of Mix 2 unless there are supported tools for SD835 chipset (hardware hacking boxes).
Also by the rules of Pakistan, you can bring upto 3 (or 5) cellphones without their brand packaging into the country and get them activated for Pakistan for a very small price 1-2k PKR without paying hefty amount of import tax. Before it was stricter for a couple of months that you had to pay more than half the price of the phone you brought extra with your primary phone.

Global Rom - where to get PCT-L29 or similar

Hi, from Australia,
I have bought UK based honor phones before, (5C not global rom - so some carriers didnt work) but would like to get an Honor View 20 global version , and know the actual model, so I can check the frequencies on frequency checker website before I buy.
I have tried Amazon India, and also tried Hi Honor, and even emailed Huawei in Australia ( long time Huawei user prior to using Honor 5C) so far no luck .
I did find a PCI-L29 for.. $1219 ,but thats a lot more expensive than the Malaysian / Indian prices.
At this level of price purchase, i am hoping to get the model that works internationally, as I found the PCT -L29 has the right bands for Australia, but very hard to buy.
So I thought this forum would be a great place to make my first post, and see what I can did up for how to buy one. Perhaps someone can share a link , if they have bought a global one.. plenty of ebay ones etc, but when you follow the link... not global .
This isnt just for me, others on some Australian tech forums also would love to know.
Thanks!
I'm in New Zealand using Pct_al10 (bought from India) I can confirm 4g and 3g work full signal on both my sims. I use Spark and Vodafone. You could lookup the bands they use and compare to the ones you need.

Hi Flamery, checked on frequency checker and not suitable (PCT-AL10 ) 5 bands missing for Australia - just in 4g) .
all those bands are available in the global rom.
Glad its working ok for you in NZ.
Maybe somebody else has a source of where I can get the PCT - L29 , or the international version, for less than $1219 AUD

I got mine from the below link. Its a local online shopping portal. Usually discount coupons are given near weekends or every few weeks. Coupons will be something like $100 off minimum $800 purchase. Which will offset the price from $829 to $729 for the 8gb model. Its local set, so warranty is only for Singapore, n region is Asia, so asia rom. I'm not sure if they do overseas shipping, u can ask them through the portal.

I have bought other phones from red white mobile previously, not sure about mobyshop.
im from germany and bought a PCT-L29 last week for 490€.
Generally most devices sold over here are PCT-L29.
if you want links to sellers send me a pm since i cant post links
I obtained mine (PCT-L29) from Technolec, from eBay. They are an authorized reseller and have been great to work with.

Hello there. I have a big question.
I have the Chinese Variant which is PCT-AL10. Is it ever possible to install РСТ-L29 Global ROM on it by the aforementioned procedure? I have NO idea if the hardware is different or just the ROMs!
