Possibility to unlock other LTE CA band - Lenovo P2 Questions & Answers

Hi guys,the Lenovo p2 only support b3+b7 on LTE CA and in my country (Italy) and other european countries it's impossible to use 4g+ because it's only used b3+b20. Is it possible to do something with QPST to unlock band? I think yes because the Moto G5 Plus is the same phone like P2 and it support b3+b20. Thanks for answer me.

Nice question: same issue here in Italy with Vodafone!

yes i need this information too. because i really want this phone but for the model i want p2a42 is A LOT more expensive than the p2c72 chinese model. is it possible to some how unlock the lte bands from the chinese model??? i seen a post of here with people unlocking bands on their quallcom phones, mostly xperia z3 i think.

North American model in Europe

I apologize for my ignorance but I figured someone with more experience could assist. I know there are specific models for the NA and Euro version but there are overlapping bands. Think it'll work in perhaps...Croatia if I were to be specific?
I was able to use my unlocked USA model OP1 in the UK, France, Germany, Austria, and Belgium with no issues so the OP3 should be fine for global use too.
What specific frequency bands are you looking for on 3G or 4G/LTE in Croatia?
it wont be a issue to use it, just will lack in some frequencies/bands which ultimately give it poorer reception and speeds
on previous oneplus one and oneplus 2, there was ways of unlocked further lte bands on the usa variant, as they all have the same processor, im sure this will be the case again, if anyone knows how ? please advise

LTE Band Support From China Sellers

Hi, I'm from South America, so, my only option to get this device is to buy one from china sellers. But I'm confused because every page like willmydevicework (I don't trust this so much), gsmarena and devicespecifications.com show different information on LTE Band Support.
For example, in willmydevicework, none of the variants (p2a42 and p2c72) supports B4 AWS LTE (1700/2100) (The band that i need in my carrier)
On the other side, in gsmarena and devicespecifications, all the variants, no matter if is p2a42 or p2c72 and 32 o 64gb storage, supports that band.
From sellers, the Aliexpress store "Eternal Team" show full band support on p2c72 model: FDD Band 1/3/4/5/7/8/20/28
Other seller, Fantacy, says that his p2c72 supports only LTE FDD B1/B3/B7.
And finally, tinydeal and Aliexpress "Lenovo authorized store", shows that his 64gb model supports FDD-LTE B1, B3, B4, B7, B8.
So, which should I trust? I'm interested only if the phone supports B4, asking for advice if someone of south america or other america's countries have the device and working on his 4G LTE carrier with B4 AWS.
Thanks in advance.

Am having the same issues like you, I want to buy from Nigeria ?? but a feed up with the inconclusive description on Aliexpress. Am looking to get the model that has LTE band 28 but non of the descriptions contain band 28 now.
Please can anyone who is already using this phone confirm the LTE bands?
Are there different hardwares/modems for p2?
Please I need urgent reply

From my experience. You can't trust any of the chinese stores with listing proper frequency's.
They even list the wrong frequency's to catch you into buying the device in question.
I highly recommend following site to check for frequency support:
Look at supported cellular networks!
P2a42 = http://pdadb.net/index.php?m=device&id=11116&c=lenovo_vibe_p2_p2a42_dual_sim_td-lte_32gb
P2c72 32GB = http://pdadb.net/index.php?m=device&id=10515&c=lenovo_vibe_p2_p2c72_dual_sim_td-lte_32gb
P2c72 64GB = http://pdadb.net/index.php?m=device&id=10930&c=lenovo_vibe_p2_p2c72_dual_sim_td-lte_64gb

Thanks for clarifying me mate, Aliexpress guys are selling the P2c72 with 4G/64G but here is the issue as I also attached, they are flashing the ROM for P2a42 in it because of play store, multi language and to sell globally but the problem is,
If you they flash P2c42 ROM on P2c72, will all the LTE band work?
Is there any hardware difference between P2c72 and P2a42?
Or is it just a modem difference, same hardware?

No the LTE bands will stay the same. Its hardware limited.
What they do is. Use the available information here from XDA how to flash the P2a42 Firmware on the P2c72.
Usually they just flash the system.img and the boot stack. You will have P2a42 Userinterface in multilingual just like an P2a42 but will still have the same LTE bands like the P2c72.
The reason behind it.
The P2c72 is sold in their homecountry (usually china) for way cheaper than the P2a42 in the western market
and they sell the modified P2c72 for a higher prices on the international market, which is still cheaper tham the P2a42 price.
By tricking the customer into listing all LTE frequency and confusing them to have "P2a42" feature. They fall for the trap.
Always trust the listing at pdadb.net
Thanks mate, the seller told me no after I put forth the question to him without any explanation but I guess this answers it.
Really need a good mid range with LTE Band 28 that ships to Nigeria.
My target was Redmi note 3 special edition but All Aliexpress stores shipping to Nigeria is out of stock. Sadly enough, they still ship to Spain.

You can use pdadb to filter for phones by bands and other features. I use that to start my research. Stick with Snapdragon based devices if you want community freedom.
Avoid Oppo phones at all costs. They don't release kernel sources and removed fastboot and any way of unlocking the bootloader.
Preferably stick with a brand that:
1. Snapdragon based phones
2. Releases kernel Sources
3. Allows for Bootloader unlocking
4. Has a community on XDA
Such as Xiaomi, Motorola, Lenovo, etc just to name a few. In not any particular order.

One thing for sure that LTE does work fine on my P2c72 towards the american LTE bands.

So, you have LTE band 4 with your carrier and your using it on your Chinese p2c72?

[G5/XT1676] Can I unlock LTE Frequencies requiered on my country?

Hi there guys!
I've bought a Moto G5 model XT1676 a few days ago, and it doesn't work with LTE connectivity on my country (Argentina)
I've asked the carrier about it, and they told me that my mobile does not work on the same frequencies of LTE antennas.
I knew that on some mobiles you could "unlock" this unsupported frequencies, could it be possible on Moto G5?
Thanks!
looking at the frequencies - none of the carriers in Argentina support lte on the moto g5
Your country uses a different standard of lte to other countries so I dont know how you would get lte working
For example the UK uses
LTE 800, LTE 1800, LTE 2600
Argentina uses
LTE 700(28), LTE 1700(4), LTE 2100 (4)
Unless there is Argentine firmware from a Moto G5 that was released in your country and you know the model number you could try flashing the modem files from that firmware - but if the Moto G5 hasn't officially been released in your country and you imported it or its not fully supported in your country im sorry but I dont know what you can do

Galaxy S20+ SM G986N

Hello to all,
i recently bought the Galaxy S20+ G986N, mine is a korean version!
Now I accidentally read that the 3G/4G and 5G networks are limited! --> I did not know before!
Is it possible to unlock the networks?
Thanks in advance and regards
Daniel
PS:
Is it possible to unlock the Dual Sim version here? Since this is a SingleSim!
Allegedly yes if you bought the phone sans mobile network, pop you sim inside and talk to someone for 10 minutes, on your local network that is, it should reset to a "domestic" flavor of networks... it can be checked via the secret menu *#60# or something like that (google is your friend if not), dough snapdragon has no issue whatsoever with working on any network, the network locked ones and usa specific ones are a different thing, - even those can be made to work.
I was not aware any of the s10 and s20 series come with just a single sim as one slot can be used for sdcard and a sim... Give it a shot, you already bought the phone anyways...
I also just mean the 5g net. I guess only the Sub6 n78 is activated here. The mmwave not at all!
The question is, does it have a software or hardware limitation? If software, which one can I install via odin?

In fact 5G limited not only by software, but by hardware too, every band protocol of 5G requires appropriate specific antenna to be installed in your device. Moreover, you can't flash anything except the firmware designed for N version (no U/U1 whatsoever options) because of boot-loader.
Thanks for your reply.
For mmwave you need hardware, but I guess for Sub6 it's only limited by sw?!?
5g supported bands are limited by hardware.
Korean models only support 5G n78.
Hope this helps

Many thanks. Of course it helps...is there's a possibility to unlock the other frequencies which aren't limited by hardware?

It's possible (4G bands) on some old phones (pre-835 era), but not so much these days though
Thanks for your reply. Not so much means, currently no possibility?

Question Gsm Bands for Europe

Hi
I bought a 11x from India and I trying to use it in the UK. The coverage is very poor due to the bands being use by India rom. Do you think there is a way to improve it.
Thank

The bands are picked by your sim card not the phone. If I stick in my AT&t sim it always uses band 4 for LTE. I have the Poco F3 global edition working in America and I have the international Samsung S10 lite working same thing band 4.
Then using the same sim .. in s21 and m11x why do I get two different data speed. My understanding was Mi11 was using a different band to s21.
