[TEST]CAUSES of MICROSD FLASH PROBLEMS

BACKGROUND:
Many people (including me) can't flash ROM from microSD card
AIM:
To help identify possible causes of the flashing errors with the microSD card method
METHODS:
Method: A trial and error test was conducted on my X1
Variables: 1) Brand: Sandisk, Kingston and unbranded cards 2) Capacity: 1 GB and 2 GB cards 3) Format: FAT32 or non-FAT32 (other format)
Endpoints: Flash successful or Flash not successful
Total cards tested: 6
Write lock: released
RESULTS:
FLASH NOT SUCCESSFUL: All cards when non-FAT32 formatted
FLASH NOT SUCCESSFUL: All cards when brand = Kingston
FLASH SUCCESSFUL: All FAT32 cards from Sandisk brand or unbranded
CONCLUSIONS:
Seems like most of the problems reported could be due to 1) non-FAT32 format or B) Kingston brand cards
COMMENTS:
Conlcusions can not be extrapolated to all Kingston cards because I tested only two Kingston cards and both were 2GB. Possible confusing factors could be considered
PLEASE SHARE YOUR EXPERIENCE to add more input

Any of these was kingston ??

Works like a charm on 8gb microSDHC from Sandisk.
Always use sandisk, best memcards on the market atm.

Nope, all of them were Sandisk.

I have a 8GB kingston here, no problem with the microSD flash method.

seriously, but then admittedly I've not looked very hard
I've promised to be a quick website for someone in exchange for a 32gb card at somepoint, but I guess they aren't in the wild yet..

Yours is Kingston "SDHC" 8GB
My cards are "normal" SD 2GB
There could be a difference...
MORE USER EXPERIENCES PLEASE ???

what about the various errors? "no image file" appears to be default - could be worth loggin these too.

No luck with the 2G Sandisk MicroSD that came with my phone.
Only tried FAT32, but tried renaming card (and not) too - just in case.

Did you format to FAT32 ?? (PS: choose "default block size)

@ gtrab - connection lagging. tried editing original message when saw already posted, so changed it - oh the web we weave
what do you mean by choose default "block size"?

@gtrab - OK penny just dropped - you refer to default allocation size of card - cool, will try next time as did not even open that drop down option.
cheers.

- Remove micro SD card from phone
(I assume you have a SD slot or a USB card reader on your PC)- Insert the card with SD adapter on your PC
- Open Windows File Explorer
- All drives are shown on "My PC"
- Right click over the SD card drive (mine is "E:")
- Choose "format"
- A dialog box pops up (see attachment, mine is spanish but should give you an idea)
- From "file system" choose "FAT32"
- From "block size" choose "default block size"
- DONT CHECK THE "QUICK FORMAT BOX
If this doesn't work, then try ANOTHER SD card from another brand

no prob with kingston 8 gb card

transcend 8gb class 6 doesnt work, gonna buy another tomorrow..

I have a 4GB Kingston Micro SDHC and that has never once let me perform an upgrade via the SD flash method.
Also I tend to have serious problems getting UC to work at all, and when it does start to work the process is never completed successfully. I just end up manually installing everything.
Have been planning on getting a Scandisk card for a while, might have to invest before my next rom upgrade!

Kingston
here's my experience:
My phone is an X1i that comes with a 2GB Kingston.
Ive used this card for flashing for 5 times already and
never encountered any errors.
i used to always format my card to fat32 with the default allocation size
everytime im going to flash a new rom. all succesful with no hang-ups.
heres whats labeled in front of my card:
SD-CO2G JAPAN
SDC/2GB 35
so, my card is not a SDHC?

Cannot flash from 16GB microsd

Not a big problem but I cannot seem to flash with my 16GB microsd. My 8GB works fine. Anyone has similar issues or knows the solution? It can be troublesome to swap cards when flashing...

I have no problem flashing from my Sandisk 16GB card. Did you try reformatting the card (FAT32!) ?

I'm using a sandisk 16GB microSD card as well, and have no problems flashing from it. What brand is your microsd card? Then again, doesn't matter in your case, as you already bought it, but for the rest of us it might be important, so that we can stay clear of that brand.

I have the same problem mate, I could flash a few times at the beggining, from then, I have not been ablo to do so, I already tried formatting it to FAT32, erase all files and jut leave a blacimg.nbh file in it and it did not worked anyway.

Same here for me
Kingston 16 GB also SanDisk 16 GB.
After some flashes it stoped working, allways shows no imagefie

worked fine
- 16gb , 2gb
didnt work
- 2x 8gb and a 1gb
but i never sorted out why they wouldnt work even after re formating

I bought one week ago a new micro SD card 16Go Class 6 from Transcend...
And I have the same problem, which is not really a problem.
I use my old 8Go card for flashing.
I read few months ago that we can't flash the touch HD from anyone micro SD card. I don't know why ?
info : Transcend micro SD 16Go FAT32 32-Kilo

if you count free space on empty cards, transcend 8gb and sandisk 8gb will show 8gb but differnt values if you look in details
seems different layout of partitions for different vendors
flashing from sandisk is always OK
transcend = no go

I am using Sandisk 16gb class 6. My other 8gb sandisk class4 & kingston class 6 works fine...

Can flash but UC does not work
I can flash using my 16 gbyte Sandisk but I cannot get UC to work. I either get an error saying the cabs cannot be located or it just hangs. Anyone else see that particular problem?
Z

Transcend are BAD. They seem to have real problems with large files such as ROM Images and MemoryMap data files.

MicroSD support

According to the official information for the Lenovo K3 Note it only supports MicroSD cards upto 32 GB. I tried my Kingston 64 GB card and it doesn't work but I am hearing that people have gotten 64 GB cards to function in their phones.
Can anyone confirm one way or another whether 64GB cards can work in this phone? If so are they specific makes / models?
Many thanks in advance.

Try formatting the SDcard in FAT32, 64GB/128GB uses the ExFat format, that's why your K3 note won't see it, this SoC don't support exFat. When you put your Sd in the phone it won't offer a formatation to work?

It didn't appear to offer any formatting options but I will give it another go.

I had to format mine on a laptop before the phone recognised it

Well it seems like good news. I put the card into an SD card adapter and then into the PC. It loaded some drivers and recognised the thing. I then formatted it using NTFS and reinstalled it on the phone. This time the phone recognised it as either an empty card or a card that needed formatting so I re-formatted it once more and it registers as a card with 58 Gb free. Yippee!!!
Currently copying the 32 Gb card onto the new one using my PC. Hopefully it will go well and then I'll copy some more stuff over just to see that it will genuinely go over the 32 Gb limit.
So far....so good

Hi,
Can you please post the further testing of 64GB Card. I am planning to buy 64GB card Class 10 SDHC please help me with your review

Well I have been using the card for the last month and all fine. I switched to limoncelo this morning and the card is still recognised with no problems. For reference this is a Kingston 10X 64 GB card. I don't know if other cards might be problematic or not. All I can say is that this is a safe option.
Limoncello nice too....

I am using Sandisk 64GB class10 UHS-1 card directly on the phone, from the day I got the phone, without any issues...

if you go to mediatek "engineer mode"> 3d tab "hardware testing> "IO" >"MSDC" >"MSDC SD3.0 TEST
There are various options such as "sd3 mode: sdhc highspeed, uhs sd12 etc etc.
Does anyone have more information on what these options mean and if they can bring any change in sd card recognition?

just wanted to share i had a sandisk transcend class 10 32 gb, 2 weeks ago i got my chinese 512 gb class10 sdhc as for test purpose for 9$ of ebay. in benchmarks it scores better.
however all works, currently i am on the phoenix rom with exfat file system support.

i just installed my 64gb sd card, and let the phone format it as portable sd card. now i have 59G ! this is under 1606 Cuoco92 custom rom.

Anyone else get any errors when formatting their SD Card? I have a Samsung 64GB

Does Sprout 4 (Canvas A1) support 64 Gb sd Card..??!!

Hii Everyone,
I am having a 32gb sd card right now in my phone. So they(brand and websites selling this phone Mmx Canvas A1) say that our phone supports 32gb expandable memory via sd-card. But in other thread i read that it is supporting a 200gb card. So, since my sd card is full, i was thinking of buying 64gb card. But please first of all let me know that if it really supports it..??
Please mention if u had 64 gb card in your phone.. or maybe if u don't have a 64 gb card then can share your experience. Thanks in advance.

Bro, if a 200 GB card is working, then a 64 GB one would definitely work.

Yes sprout 4 gen 1 does support 64 GB SDXC micro sd card and also higher capacity. I am the one who's currently having a 200 GB sandisk micro sd card and previously had the strontium 64 GB sdxc memory card that did worked fine.
Most of latest phones do support 64 GB sdxc memory cards. If the phone supports sdxc ( Secure Digital Xtended Capacity) which supports eXFat format which is microsoft patented, so that sdxc cards are pricey than sdhc (upto 32 GB) which supports fat32.
You may reformat to any readable format after buying an sdxc card (like fat32, ntfs, ext etc). However it's advisable not to mess with the format unless until you know what you 're doing,
You may blindly go for a 64 GB micro sd card. It will work out of the box
thank you

Thanks buddy, so i will order a card tomorrow. But here are two more questions in my mind..??
1) Reading sd card is situated with which part of phone. Is it hardware,software(rom) or the kernal?? Coz u mentioned there that u were using cm12.1 beta5(i am on official marshmallow 6.0.1 with thunderzap 5.1 kernal and phone is rooted)
2) Why they (brand and sellers) had written 32 gb expandable only (sorry, i must ask it from micromax itself. I will surely mail them )
And 1 more (SanDisk Ultra® MicroSDXC™ 64GB 48MB/S UHS-I Card) is good to go....

1) Both hardware & software, In windows starting from windows xp to 10. (xp needs update patch to support eXFat). In mac version 10 and after will support eXFat, so as that older andriod version (Before andriod 2.3 Ginger bread) and host devices (old phones with limited hardware spec specially ram below 1 GB) don't support sdxc sd & micro sd cards.
2) It's because sdxc format reached the enduser in 2010. Most of the newer hosts (phones) that came after 2010 with decent spec will support sdxc cards. Irrespective of OS (Either it be Mac, Windows, andriod etc.).
And why manufacturers don't mention it. Because if they mention it in the official spec, you won't go for higher end models. If a 5k phone can officially support 200 GB card then most people don't even think of higher end models above 10-25k. Even today manufacturers for their own good will not mention in spec of low budget phones that sdxc micro sd cards are supported
You may go for the card brand of your choice, since you 're using it on a low budget device. The card read/write speed doesn't matter.

Thanks again bro,
All doubt's been cleared.

[Ques] Does Moto G LTE support 64 or 128 GB SD Card?

Has anyone tried to use 64 or 128 GB SD Card in their devices? Does it work properly?

Well it should. I remember using 16gb cards my old phones, who were supposed to support only up to 8 gb. Check this out:
http://www.androidcentral.com/moto-g-2015-and-sd-cards-everything-you-need-know
Just be sure to get a fast sd card.

Yes, my Thea has a Samsung 64 GB sdxc class10 and works fine.
Some users replys problems with Samsung, some with SanDisk, ... The Moto-Support says it must be a class 10 until 32 GB...
They can read exactly the manual...
