While the school maintains a strict policy on discipline and focus, the natural curiosity of adolescence means that dating—often kept secret from parents—is a common part of the high school experience. These relationships often navigate the tension between traditional Bangladeshi values and the globalized "Gen Z" dating culture. The "Ideal" Match: Societal Pressures
This report summarizes recent events, administrative issues, and serious allegations involving Viqarunnisa Noon School and College (VNSC)
Like many major institutions, anonymous "VNSC Crush" pages often pop up, where students post coded messages or public declarations of admiration for peers or students from brother schools. While the school maintains a strict policy on

However, the walls of the school cannot keep the outside world at bay. The quintessential "Viqar romance" often involves the external male figure—students from neighboring boys' schools or colleges. The geographic reality of Dhaka facilitates this. Proximity to institutions like Notre Dame College or St. Gregory's High School creates a backdrop for accidental meetings and intentional loitering. In the pre-digital era, romance was conducted through the dangerous thrill of exchanging letters near the school gates or the fleeting eye contact during the chaotic rush of dismissal. These interactions were high-stakes; a letter discovered by a teacher or a parent meant social ruin and potential expulsion. Thus, early romantic storylines were defined by secrecy and the adrenaline of rebellion against the strict moral code the school represented.
Despite the modernization of dating, VNSC remains a conservative space in many ways. Romantic storylines are often lived in the "gray area"—hidden from strict parents and school administrators. The tension between the desire for romantic autonomy and the pressure to maintain the "perfect student" image is a recurring theme in the lives of many students. | | Bhalobashar Kotha (2024) | Maya &
: Many stories center on the iconic Baily Road campus. This area is culturally synonymous with first crushes and "gate-side" encounters, where students from nearby boys' schools (like Notre Dame College or St. Joseph’s) often feature as romantic interests in fictional plots. Academic vs. Emotional Conflict
The usage has changed and /e is only for erasing NAND memories.
To zero out sections of eMMC or UFS use the new /f fill command.
/u takes a hexadecimal value.
This should make no difference on the standard LUNs (0-7) but will make things clearer on LUNs 81, b0, c4, d0.
Qualcomm processors support two different protocols, "Sahara" and "Firehose". Sahara is supported in ROM and is always present. Firehose is implemented in downloadable loaders in ELF format.
The usual procedure is to first get your device in EDL mode, i.e. where it is presenting USB VID/PID 05c6/9008. This can be achieved by:
Everything under Windows needs some kind of driver. Zadig is a simple generic driver generator. Select "WinUSB" as the type of driver to install. Do NOT use any Windows drivers from Qualcomm. They will try to present your device as a serial port. Now you can do a simple check if you like.
This shows you that the device is connected and has the right driver.
Next, you must use the Sahara protocol to load a loader for the Firehose protocol.
Loaders are specific to processor, device manufacturer, possibly flash memory type and hash.
To decide which one you need you need to collect some basic info.
There are reports that Sahara protocol version 3.0 does not support querying the HWID or Hash.
If this happens to you, use the /qbc quirk (see below).
These files often use .bin or .mbn as the extension despite it actually being a normal ELF file. The file names are based on the 16 hexit HWID and the first 16 hexits of the Hash. By one website they are listed under the last 8 hexits of the Hash. As the filenames tend to be cumbersome, you might rename them something short and mnemonic.
To look up available loaders by Hash see this table.
For Boox Onyx devices see this table.
From this point on the processor is using the Firehose protocol and you need not (can not) reload the loader unless you reboot.
A device might be using eMMC storage (older devices), NAND storage or UFS storage (newer devices).
The /u flag must be used for all operation in Firehose on devices with UFS.
The flags /d (slot), /u (LUN), /p (partition), /s (start block), /c (count of blocks) and /b (block size) are used to specify the range of operation.
If the partition is specified then the start block is relative to the start of the partition.
If partition is not specified, then the start block is absolute.
Zero is the default for both start block and count of blocks.
Partition operations often do not specify either start block or count of blocks.
Operations on raw devices (i.e. not a partition) require an explicit /s and /c to prevent accidents like edl /f.
| Start | Count | Partition | |
|---|---|---|---|
| Unspecified | Specified | ||
| 0 | 0 | Whole device | Whole partition |
| 0 | + | Start of device | Start of partition |
| + | + | Middle of device | Middle of partition |
| + | 0 | End of device | End of partition |
| − | 0 | End of device | End of partition |
| − | + | Part of end of device | Part of end of partition |
The major operations are /r (read), /e (erase), /w (write).
The erase and write operations can be combined which yields the non-optimized operations of full erase and (possibly) partial write (depending on the size of the input file).
Be very careful when you specify /e (erase), /w (write) as not specifying a partition means the whole device!
Partitions are sized for the maximum anticipated size of the contents.
Often the fraction of a partition that is actively being used is as low as 20%.
(There are often many partitons with all zeroes in them also.)
There is no particular need to transfer a whole partition when 20% will do.
Of course, if you still want to transfer another 50MB of zeroes, just don't use the /t flag.
Also note that some images have signing or other (sometimes) necessary things after the end of the normal image.
Currently the EDL utility has the capability to recognize the actual size of:
Android images are naturally aligned to pagesize (normally 4096 bytes) but ELF files can be any size. Therefore, when they are read, even when truncated, they are rounded up to the current device blocksize (normally 512 or 4096 bytes). This simplifies matters when/if they are written back to the device.
NAND memory has two peculiarities that require special handling. The first peculiarity is that they have "bad blocks" (an erase block is sometimes 64 x 4096 bytes). During a read the output file will be filled with 0xff wherever bad blocks are to maintain alignment. During a write the input file will be skipped over wherever bad blocks are to maintain alignment. The second peculiarity is that because of the hidden CRC32 and ECC on each page, a freshly erased page must never be written with all 0xff values. The EDL utility will do explicit multiple writes (in the hundreds) around the bad blocks and the empty pages. The EDL utility will do explicit multiple reads (a few) around the bad blocks. You must explicitly erase whichever region of the NAND memory before writing but this may be combined in the same command. The EDL utility now supports NAND volume tables analogously to GPT partition tables.
Quirks are idiosyncracies, anomalies or incorrect implementations of Firehose loaders.
By specifying the /q flag you can bypass problematic parts.
/qabcd, for example, will not query serial number, HWID, hash or SBL version.
There is a default of /qad so you need to /q to display serial number and SBL version.
| A | Do not query serial number |
| B | Do not query HWID |
| C | Do not query hash |
| D | Do not query SBL version |
| E | Allow CSD read to fail (Sony Vivo) |
