[HD7 General] the archer:
Can you please post what bootloader, ROM etc is on your phone. Also can you use the full 64gb?. Thanks in advance
[HD7 General] syedabdullah:
Hi,

Bootloader version: 5.12.2250.0(135916)

OS version: 7.10.8107.79

Total Storage shown: 59.25 GB, so I guess you cannot use the full 64 GB.

This is not a custom ROM, but the same original ROM that came with the phone.

Hope this info is helpful.
[HD7 General] dorianmuthig:
So, I hope you're telling the truth and the new bootloader has indeed support for SDXC cards now, because my phone, which is not carrier restricted still has version 5.11.2250.0(134578) and only works with SDHC cards.

Would you mind sharing your Phone Model, Firmware revision number, Hardware revision number and Chip SOC version as well?

The 59.25GB part appears normal, though: 64 * 10^9 / 1024^3 = 59.60464478...
[HD7 General] syedabdullah:
Hi, sorry about the delayed responses.

Well, I wouldn't be writing here if I'm not telling the truth. :-)

I bought my phone through an auction on eBay.com and got it over to India through a friend.

Since it was T-Mobile locked, I unlocked it through cellunlocker, I didn't jailbreak it any other way.

Here are the details you wanted:

Phone Model: HD7

Firmware revision number: 2250.21.51202.531

Hardware revision number: 0002

Chip SOC version: 2.2.5.0

Additional info, if this is helpful:

Radio software version: 5.71.09.02a_22.51.50.21U

Radio hardware version: A.12.0.D4

Note, it still shows Carrier as T-Mobile US.

I use an Indian sim card.

Thanks,
[HD7 General] dorianmuthig:
Could you please correct the data above?

Here's mine (64GB cards don't work):

Phone Model: HTC HD7 T9292

OS version: 7.10.8107.79

Firmware revision number: 2250.21.51101.401 (current HTC Europe region generic provider independent firmware)

Hardware revision number: 0002

Radio software version: 5.71.09.02a_22.51.50.21U

Radio hardware version: A.102.0.D4

Bootloader version: 5.11.2250.0(134578)

Chip SOC version: 2.2.5.0
[HD7 General] syedabdullah:
Hi,

You're right, there is a typo in Radio hardware.

Here's the corrected one:

Radio hardware version: A.12.0.D4

I'm guessing the model is T9295 (Is there any way to confirm this?)

Firmware is correct - 2250.21.51202.531

The reason I am hesitant to flash my phone with a custom ROM is, I am not sure if I'll be notified of updates released by MS.

Thanks,
[HD7 General] dorianmuthig:
Don't flash a custom ROM, flash a vendor ROM for your area (via goldcard method, will run you the equivalent of ~10-15 bucks) and you should be set.
[HD7 General] syedabdullah:
Thank you, will try it out.
[HD7 General] oce:
This memory works on the HD7? My Sandisk memory (32GB) isn't compatible with my phone and it do automatically an hard reset :(
[HD7 General] kocco004:
I will try this method.
[HD7 General] Riley600:
This is a Patriot PSF32GMCSDHC43P 32GB Class 4 MicroSD card. From what I read, it is unsuitable due to the inconsistent 4k write speeds and inconsistent random 512k and sequential write speeds. Is this correct?

[HD7 General] saeedk64m:
does this upgrade memory cause to prevent update to tango?
[HD7 General] dorianmuthig:
This card won't work. (It still might, but it is below recommended spec, that 41 IOPS should be 200 on allocated sectors)

Not to my best knowledge, then again the Tango update isn't out for HTC phones, yet (only select Nokia phones). Updating will be using the same traffic scheduling method as the other 7.5 updates did.
[HD7 General] Riley600:
Thanks for the input. I'm a little confused because in this post you say that QD=32 doesn't matter as much as QD=1. Based on my results for the Patriot card, they all exceed what you've posted there for the 8gb J35A card (except the 512k random writes which are about half as fast). Or is it that I'm missing something/not interpreting your post correctly.

Thanks!
[HD7 General] dorianmuthig:
Yes, they don't matter as much, because you will likely never reach a queue depth higher than 5. However since there is an obviously large difference between the QD32 and the results without command queuing (the former should usually be faster) I would be very careful with that card as this is an indicator for sequential write optimization logic in the SDIO processor inside the card, there may even be something seriously wrong with it.

You're welcome to try it in your phone, however, the card should satisfy the absolute minimum performance requirements for 1st generation phones, performance wise. Since the last HTC vendor update, IO is cached as well, so you shouldn't run into too many issues, but the only definitive way to find out if a card works is to actually put it in a phone. Performance should be better than before (opening apps and syncing media should be faster), if it isn't you may run into problems.

And as far as the original 8GB card goes, that card is actually inadequate, performance wise, as a lot of vendor installed cards were at the time, which is an issue Microsoft has been made aware during development of Mango.
[HD7 General] Riley600:
Thanks for the info, that makes sense. From what I read, the Sandisk B35 cards can be hit and miss as well now, right?
[HD7 General] dorianmuthig:
Pretty much, but if you get a recent card, the miss part should be very low.
[HD7 General] Riley600:
Awesome, I'll order a Sandisk one and post up the benchmark results when I get it. Thanks again for your input. :)

Transcend 32gb speed 4 working !!!!

testing for any problems..
[HD7 General] xdrc45:
Finally did it!

Just finished installing a PNY 32gb micro SD SDHC class 4 card in my HD7 tonight. She seems to have a little more pep in her step! Noticeably faster boot time, transfer between screens and apps and it seems to be more responsive all around, not as much of a delay and lag. Excellent tutorial! Didn't run into a single problem throughout the whole process. The lower 1/4 panel came off with ease and without damaging it. I was actually able to remove the torx screws with a new 3/64" slotted/flathead precision screwdriver without scratching any of the screws and the metallic tape over the SD card slot pealed back and re stuck in place with no problem. So there was no real evidence that I was even in there..so for a warranty issue... I might get away with reinserting the 16gb card without them knowing I was in there!

The only thing I did differently was that I used a pencil (isn't a conducter of electricity) to hold the inner plastic protective cover up and out of the way to allow for plenty of clearance and room to work and easily access the SD card slot. If you use this trick just note that there is a wire on the inside, on the side without the camera and volume keys of the device and make sure the pencil isn't resting on it... just incase it stesses the wire or soldering joint!
[HD7 General] Magpir:
i like to know if changing the sdcard to a better class 10 ect willr esult in improved battery life?

which micro sd card has the lowest power consumption?

will class 10 give better speed?

---------- Post added at 05:47 AM ---------- Previous post was at 05:42 AM ----------

i am still having 1.54 bootloader with a HD7....running custom 8779 rom....so which card will wrk?
[HD7 General] Magpir:
Today i removed the sdcard form th ephone and reinserting it did not work

Why?

now i must go to get a new sdcard...

or should i reformat it in a nokia device?
[HD7 General] xdrc45:
Hmm...that's weird! Usually the card will only work in the windows device that it came out of until its reformatted. WP7 devices lock the card

Did you hard reset after you reinstalled it? That's pretty much the mounting method for it.

Or now's your opportunity to upgrade to the 32gb!
[HD7 General] 5ft24:
if you powered on the phone while it's out, it may not like the card again until it is formatted with the Nokia. if you didn't power it on with the card out, it may be the card died. i'd try the format first... less expensive than a new card.
[HD7 General] Magpir:
yes thats the mistake , i took out the card and powered on the phone without it.

the WP7 OS then rejected the card. So its now clear the removing the card and powering on the phone will make the card bricked and wp7 will not recognise it again., Not even hard reset. So this is why , there is a sticky material sticker holding on to the card to prevent it from slipping out.

Anyway i just paid $6.50 for a new 8GB card at my local harvey norman store, its the sandisk ending with serial number B35, now it works ,

Hd7 recognised it immediately and booted after a hard reset. Worked like a charm.... works in custom rom

Well the original card is unsuable even if i did not power it on...went to 2nd hand dealer handphone shops and tried in a variety of nokia devices, still cant format it although it is recognised .

the new 8GB card seems to work slightly faster, no issues, still monitoring battery life.

Btw the sandisk witht he exact model number posted in this thread, seems to be abundant in large quanitites at the locals store i purchased .

So if anyone wants it, just contact me

here are the details

Sandisk Microsd class 4 ( SDSDQM-008G-B35A)

tango 8779 custom rom

Bootloader 1.54

Asia HD7

U only need to look at the first set and the last set of numbers in the serial

$6.50 for a class 4 is a good deal and this card has good reviews and a test done shows its faster than a class 10 PNY

---------- Post added at 02:11 PM ---------- Previous post was at 01:54 PM ----------

the original microsd which came with the HD7, we dont even know what class is it.It might be slower?

And it seems to get laggy if u install a lot of apps on it.

is this seen with the new PNY card?
[HD7 General] Magpir:
No it may not be nodo or mango OS , it could be the bootloader. I am still on 1.54 bootloader, which is the nodo bootloader but with Tango 8779 custom rom OS , and it worked for me.

So if u want to play safe, or u want a brand of sdcard to work other than sandisk or the confirmed ones or even sandisk itself

flash a stock nodo or before OS first with the the original bootloader meant for those ( eg. 7004,7008 ect) or those bootloaders when DFT RSPL/HSPL version 1 was first released ( eg. 3xxx)

Most of the tutorials made for upgrading sdcard on hd7 are from a year ago.
[HD7 General] 5ft24:
Check on the forums for the sd unlock cab file. I couldn't find a Nokia here in the us that could first an sd card. Did a hard reset, then loaded the cab file, ran sd unlock, powered off the phone and it was recognized and formattable with my pc
[HD7 General] xdrc45:
My original SD card that came out is a Sandisk 16gb class 4 and yes the read/write speed could be slower.

I haven't noticed the PNY to be laggy since I've put it in and I have all of my apps reinstalled plus I've start to put music and pics back on it and it still seems to be working just as well.
[HD7 General] Magpir:
a qn to sdcard experts?

the the sdcard wear and tear?

of so, will it drain the battery by using a worn out sdcard?
[HD7 General] Magpir:
can we use the same card back in wp7 ?
[HD7 General] oce:
Hi friends,

i buyed a microSDHC card (Samsung 16GB, class 10) and i've do a test with CrystalDiskMark. This is the report:

Do you think that this memory can work on my HD7 ?

Thanks a lot.
[HD7 General] Magpir:
it should be able to work so long it satifies wp7 requirements ....
[HD7 General] oce:
Ok, thx. :good:
[HD7 General] Magpir:
if u must play safe , just use a sandisk.

But i must warn u first, once u take out the original sdcard and turn on the phone, the original card is bricked and wp7 will not recognise it again.

So if yr new card does not work and u put in back yr original card, the card will not work.

So take care when u do this. Just get a sdcard u know works...

or

flash the xmod rom and unlock cab first to yr original card and unlock it before u do anything , take it out and put in the new card. this way the original stock sdcard can be formatted in PC and is usable again if yr new card does not work

This is a security mechanism that is built into wp7 to safeguard user information

---------- Post added at 04:42 PM ---------- Previous post was at 04:27 PM ----------

the original sdcard may not even be class 4. Some here claim its only class 2 but performaig like a class 4 as apparently sandisk card performance is different from other manufacturers who advertise the same speed class. i think they are refering to sustained read and write . or it may just be a generic card with modified parameters during manufacturing.

The original sdcard does not have any markings on it and i beleive its the OEM like HTC who choose this cards to work with their phone, not microsoft. wp7 OS may itself have minimum requirements for the card , just like the regular windows OS

it could be that for sandisk

class 2 = class 4

class 4 = class 6
[HD7 General] xdrc45:
Agreed...more than likely because of how old the card is and when it was manufactured it's actually a class 2 but performs like a class 4.

Although my original 16gb card does have a class 4 stamp on the card and you say yours does not... I don't know if this is because of the time frame that my device was manufactured or that it is an actual TMobile US device. I bought it new from TMobile in April of 2011 in the US.
[HD7 General] xdrc45:
Yeah, it looks as though the SD card should work well for you. From what I understand...The Random write/Sequential write and the Random read/Sequential real all match very well and the 4KB read/writes also look to be good.
[HD7 General] Magpir:
when we look at the hd7 sdcard we are likely looking at cards from 2009- 2010 which were mostly class 2. So this card may be modified one with higher speed. OEMs tend to choose the ones which are cost effective

since then commercially sold standalone cards may have caught up and this is why 2-3 years later when we change it we are able to make it work

also thanks to xda members who used the original card to test it before posting the rea/write speeds. fromthis we had an idea of the speed class needed for wp7

So i beleive most cards purchased recently which a class 4 should be able to work . just make sure its a big brand bname like sandisk, samsung ect...Personally i would avoid kingston ...But generally if u want to change/upgrade yr HD7 sdcard , then those that are microSD HC class 4 released recently in the last 1 year and above and advertised for general usage like mobile phones, cameras and PDAs should work . Of course u should not get those expensive cards like SDXC which are meant for high speed digital recording cameras , these may not work as they may be using newer technology.

for those interested, u can Pm me for purchasing the card. I am located here in Singapore.. and this card that is perfect match B35 is available in large quantities .

if i can get 5 orders and above for PM. i am willing to send to u ... if u purchase from me

the available sizes are 4,8 , 16 and 32GB

Im planning to sell my old HTC 7 Pro and I have a great Samsung 32gb class 10 card in there. I was thinking of downgrading it before selling so I can keep the card for future devices.

I wonder about this card, would it work because of the few slow numbers:

[HD7 General] Dr.8820:
Haven't visited this thread in awhile, but I'm allegedly getting a new replacement phone and I just picked up a SanDisk Ultra class 10 64GB from Best Buy for $59.99....I'm going to try it and report back. The number is SDSDQUI-064G-A11 if this works....
[HD7 General] emil_bg:
can we use any other card then sandisc?
[HD7 General] xdrc45:
You can use other brands of SD cards, if there newly manufactured....but I would recommend using a higher quality card over some of the really cheap ones available, there better made and typically your less likely to have problems with the Read/Write speeds.

I'm using a PNY 32gb class 4 SD card in mine for months now and recently just put it in my new replacement device and have not had any problems with it. It cost me $35.
[HD7 General] Dr.8820:
Yeah, I tend to stay away from the off brand ones, and I try to buy them from retailers because I got burned years ago buying one off eBay. If this works and with a brand new HD7 with 64gb....I will definitely be sitting out the first round of WP8's!

I can confirm that Toshiba microsd 32gb class 4 doesn't work. Its read and write is too slow for our phones. Model: sd-c32g2cyd. Stay away from this one guys. :rolleyes:
