[Tutorial] How to flash Spreadtrum | Unisoc .pac firmware using Research Download Tool

Requirements

• Download Research / Upgrade / Factory Download tool
• Spreadtrum phone
• Install Spreadtrum SCiU2S USB drivers
• Download Spreadtrum firmware / pac file/stock rom

If you encounter any error(s) before or during flashing then see our list of Research Download / Upgrade Download tool errors for how to fix

How to use the Research Download tool / Upgrade Download tool

The steps below explain how to use the research download tool or upgrade download tool to flash a Spreadtrum PAC file

• Open the download tool folder

• It's essentially the same procedure to use the Research, Upgrade or Factory Download tool.
• This tool is for Spreadtrum chips only. It will not work on any other chipset
• This tool only flashes firmware in .pac format. If the firmware you downloaded is in zip format then unzip to view its content. If the content isn't a PAC file (but each partition's files) then you need to convert it to a PAC file in order to flash using this tool
• Dumps made using Infinity Chinese Miracle II SPD are usually in .pac.sc format and can't be directly flashed using this tool. You'll need to convert the Infinity CM2 SPD pac.sc to pac format
• For some phone models, you might need to hold the boot key (could be either volume up or volume down) throughout the flashing process. This is to enable the flashing to continue in the face of a connection-disconnection cycle
• If you wish to flash selected partitions (using the Research Download tool), FDL 1 & FDL 2 are required to be flashed also.
• You should only flash a pac file for your phone model and build number/variant. Flashing anything else could brick your phone
• Do Not interrupt the flashing process as this could brick the device. If the flashing somehow gets interrupted, take out and re-insert the battery then retry the flashing
• Hold the boot key (volume up / down button depending on your device) till flashing is well underway. You might have to hold it throughout flashing for some devices.
• This tool was created by Spreadtrum Communications Inc. so credit to them for the tool

Quote: In this video tutorial, I'll be explaining how to use Research Download tool. You'ld usually use this tool when you wish to flash a Spreadtrum-based phone and you'll need to have your drivers which I have here and your Research (Upgrade or Factory) Download tool of course and your PAC file. Your PAC file is your stock rom. In the case of Spreadtrum, its in packets. You need to have your PAC file. I'll be using Itel 1452 for this video tutorial and you'll need your Spreadtrum phone. First thing is to install drivers In my previous videos, I explained how to install VCOM drivers for the Mediatek and the Spreadtrum drivers but just for those who might have missed the video, I'll be taking you briefly through how to install the drivers in this guide just to make it easier for you so we have a start to finish approach. You could also visit our website to check the video or guide yourself so you can manually install the Spreadtrum drivers yourself if you ever need to. I have everything I need. I'll install my drivers. I have the SCI driver; the Jungo and the Spreadtrum (USB) drivers so you just open a folder. The particular driver you'll install depends on the kind of PC you have. If you're using a 32 bit, you'll of course open this (x86) folder. I'm using a 64 bit PC for this tutorial so I'll just open this (x64). Just double-click this (DPInst). Now, before you proceed with this, its very important that you disable signature verification on your PC. I'd shot a video on on that. You can also check our website on how to manually disable signature verification on Windows PC ensure you do that because if you don't, you might not be able to install unsigned drivers. What you just need to do is click Next. I'll be installing both drivers using this same approach My drivers were successfully installed so I just click on Finish. Next up is to install the other drivers SciU2S 64 bit (based on my PC). Just run this, click Yes to confirm and just proceed.  That's all If you encounter any error at this point, what you just have to do is manually install the drivers you can check our website for how to manually install Spreadtrum drivers, you can also see the video Drivers installed. Next is to launch Research Download tool. I run as Admin just to avoid permission issues Click Yes to confirm. OK, we are open here. At this point, you'll want to disconnect your Spreadtrum phone If the battery is removable, remove the battery and slot it back in just to make sure that the phone is switched off. At this point, my Research Download tool is up, you'll want to load the packet (file). Click on Load Packet In the Window that pops up, select the pac file. Its very important you do not flash the pac file meant for a different model to your phone if not you're going to have serious issues. Flash the pac file for your model so I'll load this pac file. Its quite important you're patient with this because (I have not responding) It could be quite slow depending on your PC type. Now, this is loaded. I'm ready to go ahead with flashing all I have to do is just click this Start Downloading button but sometimes, you might encounter a couple of errors so I'll just take you briefly through some things you can do to avoid some errors You could get the NVdata failed error. If you ever come across that, all you need to do is just come to your Settings - Backup. If you're having the NVdata or some kind of NV error, untick all these items then click on OK. When next you flash, you'll not be having NV errors. You can also select which items you wish to flash In this case, the FDL 1&2 are compulsory for you to flash. You might selectively flash some items In this guide I'll not be flashing all items. I'll be flashing just cache to avoid any problems although the pac file is meant for my phone, I just want to make this flashing a lot faster by disabling all other items except cache so I have a fast flash. If you intend to flash all the files, you don't need to some here, just go straight to Start Downloading but in my case, I want to selectively flash. In a case where you have pattern lock maybe the owner forgot his pattern or something. What you'll want to do in that case is just flash userdata In that case, you would have your fdl files ticked and userdata (then maybe cache) ticked. Those 4 files. So you just go ahead with flashing. Basically, you can flash only what you want like recovery system.. tick whatever you want to flash. I have my 2 fdl files and cache ticked so I click OK. Remember this part is optional so you don't have to go through all that setting. I have everything set up, I'm ready to flash. Everything is good to go. Next, click Start Download and you'll have progress bar saying waiting At this point, remove your battery and slot it back in (if removable). Make sure the phone is switched off then connect the phone to the PC while its switched off (battery inside). Ensure the battery is well charged If after connecting to PC, all you still see is waiting (i.e nothing is happening). It likely you didn't install the drivers correctly so you might want to go  back to that step or your port is faulty, might want to change your port or in some cases, you might need to hold down the Volume down button while connecting to the PC but for some phones, once you just connect directly, it starts flashing. For phones like this one I'm holding you need to hold the volume down / decrease button while connecting to the PC for flashing. [connecting] My flashing has begun. Alright! My flashing was successful, my phone is going to reboot. So basically, that's how to use Research Download tool. You could decide to flash all the files and come straight to Start Downloading (I can click Stop now) or selecting which files you'll flash by going to Settings then unticking any unneeded item. That's how to use Research Download tool

Read Our Research On:

More than half of Americans are following election news closely, and many are already worn out

A majority of Americans say they are closely following news about the 2024 U.S. presidential election, a slightly higher share than in April 2020. At the same time, many people already say they are worn out by so much coverage of the campaign and candidates, according to a Pew Research Center survey conducted this April.

To examine Americans’ habits and attitudes toward political and election news and information, Pew Research Center surveyed 8,709 U.S. adults from April 8 to 14, 2024.

Everyone who completed the survey is a member of the Center’s American Trends Panel (ATP), an online survey panel that is recruited through national, random sampling of residential addresses. This way nearly all U.S. adults have a chance of selection. The surveys are weighted to be representative of the U.S. adult population by gender, race, ethnicity, partisan affiliation, education and other categories. Read more about the  ATP’s methodology .

Here are the  questions used for this analysis , along with responses, and its  methodology .

Pew Research Center is a subsidiary of The Pew Charitable Trusts, its primary funder. This is the latest analysis in Pew Research Center’s ongoing investigation of the state of news, information and journalism in the digital age, a research program funded by The Pew Charitable Trusts, with generous support from the John S. and James L. Knight Foundation.

How closely Americans follow election news

More than half of Americans (58%) say they are following news about candidates for the 2024 presidential election very or fairly closely. Another 28% say they aren’t following it too closely, and 13% aren’t following it closely at all.

The share of Americans who are closely following election news is slightly higher now than it was in April 2020 (52%). In October 2020, however, that share increased to 75%.

This year, Republicans and independents who lean toward the Republican Party are slightly more likely than Democrats and Democratic leaners to say they are closely following election news (64% vs. 58%).

As in past presidential elections, older adults are more likely than younger adults to say they are closely following news about the candidates. Roughly eight-in-ten U.S. adults ages 65 and older (82%) currently say this, compared with 68% of those ages 50 to 64, 48% of those ages 30 to 49, and only 34% of those ages 18 to 29.

Fatigue over election coverage

Although many Americans are following news about the 2024 presidential candidates, they are also experiencing fatigue over election coverage. About six-in-ten U.S. adults (62%) already say they are worn out by so much coverage of the campaign and candidates, while 35% say they like seeing a lot of this coverage.

This is similar to the share of Americans who said they felt worn out at later points in the last two presidential election years. In June and July 2016 , 59% of Americans said they felt worn out, and in October 2020 , 61% felt this way.

Americans who are following election news closely are less likely than those who aren’t to be worn out by election coverage. Four-in-ten Americans who say they follow news about candidates very closely say they are worn out by so much coverage, compared with 77% of those who say they don’t follow it closely at all.

Republicans are slightly less likely than Democrats to say they are worn out by election coverage (58% vs. 66%). This gap is driven by conservative Republicans (55%), who are less likely than moderate or liberal Republicans (65%) to feel worn out.

How Americans come across election news

Americans are more likely to say they mostly get political news because they happen to come across it (57%) than because they are looking for it (42%).

However, there are striking differences on this question by age. Just a quarter of Americans ages 18 to 29 say they mostly get political news because they are looking for it, compared with 60% of those 65 and older – a gap of 35 percentage points.

Those who say they closely follow news about the 2024 presidential election are also far more likely to actively seek out political news. About six-in-ten U.S. adults who closely follow election news (58%) say they mostly get political news this way, compared with 18% of those who are not closely following election news.

Republicans and Democrats are equally likely to say they mostly get political news because they look for it (44% vs. 43%). However, independents who do not lean toward either party (21%) are about half as likely to say this.

Sources of election news

We also asked what type of sources Americans get most of their political and election news from. A majority of U.S. adults (62%) say they get most of this news from journalists and news organizations. (The question did not ask how people access that news , such as through TV, print, news websites or social media.)

Around one-in-ten Americans (11%) say they get most political and election news from friends, family and neighbors. Smaller shares say they get most of this news from celebrities and social media personalities (4%), politicians and political parties (3%), and ordinary people they don’t know (2%). An additional 17% say they don’t get most of their political or election news from any of these sources.

There are a few differences in election news sources by Americans’ age and political party:

• Older Americans are far more likely than younger ones to say they get most political and election news from journalists and news organizations. Around three-quarters of Americans ages 65 and older (78%) say this, compared with 68% of those ages 50 to 64, 55% of those 30 to 49, and 45% of those 18 to 29.
• Adults under 30 are significantly more likely than those 65 and older to say they get most of this news from celebrities and social media personalities (10% vs. 1%). They are also more likely to get this news from friends, family and neighbors (18% vs. 6%).
• Democrats are slightly more likely than Republicans to say they get most political and election news from journalists and news organizations (69% vs. 59%).
• Republicans are slightly more likely than Democrats to say they don’t get most political or election news from any of these sources (20% vs. 12%).

First-principles study of optoelectronic properties and electric field modulation in pbs quantum dot/graphene hybrid systems.

The hybrid dimensional system of quantum dots and graphene combines the excellent photoresponsive properties of quantum dots with the ultra-high carrier mobility of graphene, providing a promising platform for the next generation of high-performance photodetectors and image sensors. However, further research and development are needed before this system can be truly applied and commercialized. In this article, the optoelectronic properties of the PbS QD/graphene system are studied through first-principles calculations based on density functional theory. By establishing a series of PbS QD/graphene interface models, the interaction between PbS QD and graphene is investigated. From the perspectives of electronic states, wave function coupling, and interface charge redistribution, the interaction between different halogen-passivated low-index crystal facets of PbS QD and monolayer graphene is discussed.The analysis demonstrates the PbS QD/graphene system with the strongest interaction among all established models. Furthermore, the enhancement of interaction between PbS QD's nonpolarized crystal facets and graphene is analyzed. Additionally, the modulation effect of an external electric field on the PbS QD/graphene system is studied. It is found that changing the direction and intensity of the external electric field can cause approximately linear changes in the system's energy level positions and charge transfer, which is very useful for manipulating device performance. Finally, computational studies and discussions on the optical properties of different PbS QD/graphene systems are also included in this work.
