Problem following Internal SD replacement

Sooooooo, I replaced my internal sd card with a 4gb class 10. I used the "cut away the plastic" covering the card method because I was too lazy to take the phone apart. Now the phone will not turn on. Tried placing the original card back in......still nothing. Plug the phone in and I get a battery symbol with a yellow triangle and exclamation mark. Any thoughts?
I pried up the one edge of the piece of plastic that I removed which was close to the contact for the back cover, so maybe I messed up that contact and the phone thinks the cover is not on there? Was there not a fix for the Streak to eliminate the need for the back cover to be on for powering up?
Any help is sincerely appreciated since I now have no phone, which is clearly not going to be warrantied. Congratulations me

Don't know if this helps because it requires what you didn't want to do - take your Streak apart. But a quick look at that tutorial and it seems that the 'switch' for the back cover is not near the internal sd card, so perhaps your problem is something different?
Did you do a reset from the recovery? I believe that you need to di that to initialize the new sd card?
There are a few threads here and at MoDaCo dealing with the replacement of the internal sd card, more reading may be in order.

The innerSD is the black square in the top right corner, slightly to the top and right of the sd card picture (that is the outerSD slot)
The battery cover switch is near where the greenish square in the bottom left corner.
It's possible he might have damaged a trace that connects the switch, but it seems a bit unlikely for it to run exactly where cut and also happened to be the only trace damaged.
You could try installing streakdroid as it ignores the batt cover switch, assuming that's the only issue

Can we use microSD card reader for innerSD card too? Does fixing innerSD helps power on our device(not booting but just power on)?

The inner SD Card is just a 'normal' micro sd card, so yes if you remove it you can put it in a card reader.
Whether making sure that the inner card is working properly it will fix your problem is unknown.
If you have not taken your Streak apart I recommend cutting the area above the inner card to remove it. I have done this to two Streaks with no issues. YMMV.

Thank you marvin,
Ill try it tomorrow, hope it will fix the device.

The innerSD is formatted in ext3, so you'd need to be able to read ext3 partitions if you wanted to examine it's contents

A few days ago I used TheManii's guide for flashing an image to the innerSD and it went off without a hitch, and solved a small error I was getting when booting into recovery. So if you want to eliminate a variable, I would highly recommend that so you know it has nothing to do with your problem

[Q] Volume down button is broken :(

Hi,
My phone had the dead-touch-screen syndrome & I got fixed by a repair shop.
Now it's working ok but during the fix they broke the VolumeDown button!
Is there any way to go to the bootloader?
Thanks,
WH

this should be in the Q&A forum, this forum is only for roms and kernals
You should be able to connect your phone via USB to your computer without turning on SD card mounting, I think you need the windows mobile software installed on your computer so that the phone can be detected and then initiate the flashing program which should be able to restart your phone and flash it... I may be wrong about some roms but I know the official windows mobile ones could do that without forcing the phone to boot into the flashing screen with the volume keys.
once you have ClockWork recovery installed you could successfuly navigate it using just the up arrow, back answer and hang up keys.
You will get stuck if the flashing doesnt work though, as you wont be able to force it into the HSPL page if the rom wont boot... so you have an increased possibility of bricking your phone if something goes wrong as you are cutoff from most of the unbricking techniques. With android NAND that is really only a problem when doing RADIO's and MAGLDR, once those are on you only need to hold down the hang up key to get into recovery and you can navigate slowly with just the up vol key
oh and you also will no longer be able to flash form your SD card to return it to factory settings, as that requires the vol down button as well

If you are sure they broke it, bring it back to the shop for complaint.
Htc broke my speaker and they fixed it for me free.

Had exactly same problem. They fix it in service.

you should give a good slap to whoever fixed and actually broke one of the main accessibilty.
demand a repair. its a very crucial button.
**note: actually the volume flex in hd2 breaks very easily. it requires a very minimum full bend to loose the metallic layer strip inside the plastic sheath.

Hi all,
Unfortunately I can't return it easily
I got it fixed in China as it was not easily fixed where I live
Is there any way I can fix it myself?
I'm an electronic engineer & fixed many mobiles before but I know it's not easy to open the HD2 & I don't want to lose it
I've checked many YouTube instructions on how to replace the screen but nothing for the volume.
Anyone have photos on how the volume button look like & what is the part number to buy I'll really appreciate it.
Thanks guys,
WH

Its pretty easy to take the hd2 apart... I think you should just grab another flex cable with a working volume buttons... usually I find broken hd2 in my town for 40-60 dollars
Sent from my LG-P999 using XDA App

actually i had taken apart my HD2 to clean the dust around the light sensor and also dirt around the power button.
i didnt take a clear shot of the volume buttons. but these shots which i took that time should give you some clear view.
THIS is the original htc hd2 disassembly / assembly video

My Snaps:
**The area marked red IN THE LAST PICTURE is where the volume button flex is located
The area marked in red are the area where you need to insert a plastic [namely an old credit card] to separate the panels

LG E900 Memory card not working problem solution

Hey guys,
I have found a solution to solve the hardware problem with the LG E900 Optimus 7,
showing the message 'Memory card not working' Your memory card has changed, is damaged or is non-compatible.

Flashing a new firmware or restoring images with zune does not solve the problem!
This message, if shown on a LG E900, implicates a hardware error with the NAND flash memory,
a Toshiba THGBM2G7D4FBAI9.
The memory chip is soldered to the top layer of the 2-layer mainboard, together with the led, sim card holding, head phone jack...
You can see it in the middle of this pic:
The hadware error is probably issued by broken solder joints, in turn probably issued by changes in temperature and/or physical exposure.
Following solution worked for me: (tried with one phone one month ago)
I heated the Toshiba memory chip with a heat tool with around 200 degrees Celsius (400 degrees Fahrenheit) for around ten minutes,
this is a technique sometimes used to repair broken graphic cards, please search google for this if you think there's something fishy going on here.
I used a 340 degree heat tool, with a 2cm distance first until I saw some solder balls, 'dripping' out, I increased the distance to 5cm.
After reasembling the phone works and does still work without problems.
Although this worked for me, it does not mean that it will work for you too.
Please try and comment, if it worked for you!!
Heating the memory chip should solve the problem not only temporary, if you get the same message some time afterwards, try again with more degrees (max 300) and/or a longer period (max 30min)
If you do not have the ability to heat the memory chip with a heat tool, you may trie to bake the whole mainboard layer. A problem could be a smelting head phone jack.
More information, pics at the www: manuga.bplaced.de
(i'm a new user and not allowed to post outside links)
If you find some language, logic or explanation mistakes in here, please tell me!
I hope that I find time to provide more information on the website mentioned above, I currently do not have much time to provide detailed phone dissasemble, assemble information, please search youtube for such vids.
Feel free to ask any questions in this thread or on my website.

Hope it works.
Going to try this out today, will let you know the results later...

Dear Guys,
I tried it (with Dremel Versatip tool with appropiate distance) and now phone even doesn`t react for on/off button. Nothing happens after switch on the charger.
Before "my fix" after charger on it shows "memory card error".
I assembled it couple of times in order to check if everything is on its place.
So now phone is completelly dead (in final nothings happen .
Any ideas?
rgds,
G.

Same problem...
Also gave this a shot, managed to get the solder to 'drip' out but straight after the chip itself actually caught on fire... perhaps a little too much heat? =P
Now can't boot past the LG logo with the top board attached. Strangely it boots up perfectly if I disconnect the top board, however this is somewhat useless since the digitizer and SIM are both located on this board. Perhaps a lost cause...

I had almost the same issue (I did not catch a fire on memory chip). After disconnecting top board phone boots, but because of unworking screen I can not proceed with anything.
After switching on the top board, phone does not want to start at all, not even giving me a LG logo on screen. No reaction on on/off button.
Have no more ideas what to do...?
rgds
G.

no boot only LG logo! Solved
I had a similar problem , my phone was frozen at LG start screen , i removed the memory board , i put it in the oven for 10 mins at 180 °C, put it back all together , and it worked!!!! i could save all my pics and video !!
THANKS a lot!!!
*pic in attachment

tanks so much, its worked for me, i have heat the memory chip with a heat tool for few minutes and ok.

I also attempted this repair. Removed the top part of the main board, insulated a few parts like the headphone jack with blu-tack, flooded board in flux, (even though none of it went under the chip...) Then I put the board in oven until infrared thermometer showed 240 degrees celcius on the chip and opened the oven door. After waiting for the board to cool down, cleaned with isopropyl alcohol, reassembled. Works, for the time being.. Thanks for info and ideas guys. :good:

I put it in the oven for 5 mins at 180 °C, it worked and I can recover all of my pictures. Thanks!

It worked! Thanks guys for help
Put it in at 180°C for 10 minutes.
All best.

Brand new Axon 7 - screen problem / corruption (video card problem?)

Hi all,
I just got a new Axon 7 from Amazon. Not refurbished, not open box - brand new.
Charged it up, started it and I get this madness :

The artifacts jump around on their own a bit, but also when the screen is touched. I removed the screen protector but the issue remains. So, I went to recovery mode, formatted data/cleared cache/reset to factory. Still the same. Just to be sure, I re-flashed B25 stock image from EDL mode, but it still shows the same screen/graphics corruption. Thoughts?

@heliosol ... Don't mess about - send it back to Amazon.

That's hilarious... One of the weirdest things I've seen in a while
Probably something wrong with the GPU, since you said that you reflashed the system. Do an RMA, don't you dare touch the bootloader

It's Amazon. Send it back and demand a new one. Why are you messing with it and potentially screwing yourself out of being able to return it?

To clarify (and add to the hilarity?): I bought an Axon 7 about 4 days ago. It had no display issues, but my SIM card didn't work in it and it had a tendency to not wake up from sleep (i.e. I press the power button or let it time out and then the only thing that would get it going is holding the power button again). I figured maybe it's my SIM card, or micro SD, or maybe some bug in the OS. Pulled out SIM and micro SD, re-flashed stock a few times, no luck. Send it back to Amazon.
Got a replacement. This one, with the screen issue. I am not at all messing around with it, it's going back on Monday. I just wanted to see if someone else was having similar issues with it -- perhaps it was some common thing that did not require a return and exchange. Doesn't look like it!

The bad thing is that a bunch of phones have every kind of trouble you can get on a phone. The good thing is that ZTE replaces them. Hell you can even RMA your phone if you messed the software so much that you can't see the ZTE logo...

You probably need to post screenshots of your device info page and firmware versions. One though is was this plug and play? or did you have to wire it? If you had to wire it perhaps the one of the power wires is not connected and the device can't keep power to the unit when you turn the car off. These things need access to power to fast boot. Mine has a setting to keep the unit on for a while after shutting car off, but that's not the fastboot option, on mine fast boot is just built in, no settings(that I've seen), which is why it may be hardware or wiring.

everything is wired correctly no extra wires , I contact the seller they told me they basically disable the features so I don't need to mess with it but that's the thing I want to mess with it lol

I guess the question is are they telling you that what you have is normal operation? Seems odd but perhaps they have no Fastboot.

Right and for the most part for most units I would agree with them, but are they saying your unit is designed to cold boot when car is turned off/on?

I'm not sure what they're trying to say I know I've been asking them since May of 2020 about it lol and nothing , I just know like 3-4 of my old androids I had the sleep option ,car settings the extra settings all them other features this one I bought it cause it said it had split screen but only one app opens the split screen which is igo but it closes as soon as I press split screen option and this one also has hdmi put in the back besides it being a 10" because I bought a SUV but it's not working like I want it to , I been thinking of changing like software/mcu I think it is idk . do you think that would be a good option to do ?

I can't speak for what custom firmware options you have, but I can tell you I have no sleep options either, what I have is a single option how long to leave unit active after accessory power is off, but no options for how long to sleep before hard power off. As I understand it most units won't hard power off for several days. I've only seen mine hard boot once when I wasn't pushing the reboot button.
