Has anyone ever thought about whether it would be possible to increase the ram/upgrade memory in a G1. As outlandish as this might sound.. similar things have been done for a variety of devices.... if possible it would probably be the number one speed booster out there? or are there certain limitations out there that would make that impossible... Anyone ever opened up a G1?
This might be what you are looking for
http://forum.xda-developers.com/showthread.php?t=566410
Theres some ram on the g1 that isnt being utilized by default.. this hack, for specific roms, can push the g1 to use more of the rom that it initially comes with. as far as a PHYSICAL upgrade im not too sure how that would work out.. never opened a g1, due to warranty void
This does happen a lot nowadays. Original Xbox's (before v1.6) had extra 'spaces' for RAM chips.
Simple to do, if you can find the right RAM for your device, which was hard enough for the Xbox until a German manufacturer was found.
http://www.xbox-linux.org/wiki/Upgrading_Xbox_RAM_HOWTO
Edit: Also remember, this only works if there is an extra 'space,' piggybacking does not work 99% of the time (and I doubt there would be enough space within the housing...)
so the question would be is there anyway to open the g1 remove a ram chip and solder on a higher capacity one.... I mean wouldnt that be awesome...

I was actually referring to how the Xbox got more RAM, by adding ANOTHER RAM chip. Possibly higher capacity would work, but I don't know **** about drivers or software compatability blahblahblah. I'm only good for actually putting it together not knowing how it works :3

There is nowhere to put it.
Ram and rom come integrated on the same chip: samsung k522f1gacm-a060
You need to find a compatible chip (as mentioned, the one from magic or hero *might* be compatible), you also need to program it with something... which you may need to hack together since there is no such thing as a dream with 256MB ram, etc.
hmmm....ok... so not possible to replace the chip flash a custom rom? Maybe we can have some bricked g1's donated to see what can be done...

I never said it wasn't possible. I simply said that what is there must necessarily COME OFF in order to put another one in its place.
And yes, you most definitely CAN program these chips outside the board, as long as you have the right equipment to do so, but the big question is to "program it with WHAT?".
Well according to this video our phone uses standard DDR ram made by Samsung. So I belive this is very possible.
Anyone wanna donate a bricked phone for tinkering hehe.

As lbcoder has stated, finding a compatible chip isn't the problem.. it's a matter of what do you program onto the chip? Simply replacing the current chip with a blank one wouldn't do anything.
WELL, I don't know if this will work but I tune cars, where you use a eeprom reader get a dump off the old chip into a hex editor and then just burn it onto a new chip with changes made and just stick the new chip with new maps on it.
Would it be possible to do something like this with this chip? Just do a complete dump of one to another?

Yea thats the way it would be done. You'd have to hex-edit the dumped rom to address the right amount of memory for the new chip and it should work. I'm certainly not going to be trying this myself but it would be an interesting experiment.
Anyone know someone who has the smarts to do that... find me someone and I'll find you a few bricked g1s ...probably the only way to get them unbricked anyway.... or I have a g1 here whose wifi does not work. I bet you there are a ton of g1s out there where this or that does not work but that would be fully suited for something like that.
Anyway lets find a genius or a few that are brave enough to go where no one has gone before... I'd be pretty certain, that twice or four times the Ram would be a pretty dramatic experience.... imagine the possibilities with ram discs.... etc...

Believe it or not guys, my wife can do this. LOL. (I did marry the perfect woman, she also fixes my cars, folds the laundry and gives the best blowjob on earth). I digress <grin>.
If someone wants to donate a couple of bricked phones, I can get the chips swapped out. The issue of hex editing doesn't scare me at all I've been doing that for years, but finding the right addresses could be interesting. I'd probably need help with that as it is a lot different then bipassing a cd check on a video game
i work with embedded devices and here are my 2c about this, but take this lightly, I havent looked at how the G1 is setup on a board yet, nor do I know what hardware it is running.
if there is external ram, then perhaps it is a matter of swapping out the chips, given that they have the same pinout/packaging, etc.. if that was the case, you wouldnt get even another bit of more addressing because to get another bit, another wire is required to address it.
if the ram is internal on the microcontroller, then it would need to be swapped out, and good luck desoldering/soldering a BGA chip by hand. if you manage to find a new MCU with more internal ram to put on, the pinouts would have to be identical or else things might not work. additionally, you would need to have some method to kind of bootstrap the MCU because they typically come blank from the manufacturer.
Ok this is getting interesting... the easiest way to find out is probably contact HTC.. does anyone know someone, or is there a way to contact an engineer... or can anyone look up the specs? If it is using standard ddram by Samsung.. there might be a possibility.
Let me see what I can find for bricked G1's than we might have redir's wife take a look at it.. or John5788, if you'd volunteer. PM me your contact info...
We could just check the service manual, no?
edit: i tried to upload it, but the upload script here blows..
mediafire to the rescue! [download service manual here]
i just looked through the service manual, nothing specific about the ram/mcu locations. everything is just located on the mainboard without any sort of diagram. the people that look at the service manual dont need to know the device at that sort of hardware level.
hi, i bought a hd2 off eBay and the guy i bought it off had tried to install android on the NAND memory and it now wont turn on. i have tried the hard reset, the phone will vibrate once when you press the power button then go to a clear screen, like the back-light is just on i need help urgently.
Sorry if this is a dumb question, but have you tried powering on while holding the volume down button?

If you can not get to the bootloader by holding down the volume down button while powering on then the HD2 is bricmed and will ha e to have a JTAG used on it or replace the mainboard. Sorry friend but it sounds like the guy you bought it from new this when he sold it.
You're best off disputing it on eBay and trying to get your money back as to JTAG a device is a complicated procedure. He probably flashed a bad radio which lead to the phone dying (not battery).

Same problem here - fortunately, I've still got access to the bootloader
If you can't get into the HSPL bootloader by holding the volume control down, so that you can reflash the NAND ROM then I would dispute via eBay. Especially if the ad showed the HD2 to be operating correctly.
i bought the phone as is because the guy i bought it off read somewhere it can be fixed he couldn't understand how to do it and apparently yo can take out the nand memory and put a working one in.

My knowledge of ebay rules & regs isn't great, but from the sounds of it the guy's done nothing wrong. If he sold it to you having stated that a component needed replacing and that it was sold 'as-is' then I imagine you've got no comeback. Have you looked into the problem yourself? (ie how much to change the mobo on an hd2?)
Sorry dude, but I think this is one of those 'learn from' mistakes. Hopefully you didn't pay much or can at least sell it on in the same condition...

Sorry but like I said before the only two ways to fix a bricked HD2 like you have is to use a JTAG on it or replace tbe intior mainboard. The NAND chip is not replacable as it is secured by a hard opoxy that requires a very higb temperature to melt and this will ruin the CPU and the intior mainboard. Go to the thread I linked below and read you will seewhat I mean.

+1. JTAG is most likely your only logical shot here. Not many do it, I do this for HD2's but I see you not in the US and may not want to send it to me. Good luck with whatever you decide!
Alright, I'm an idiot and should leave the hacking to the hackers. I've managed to hard-brick my RAZR M. It acts like it has no battery.
I thought hmmm... if the bootloader unlock exploit targeted the TZ (TrustZone) partition and the OTA patched out the TZ exploit, maybe I can downgrade the TZ partition to bring it back! So like the idiot that I am, I "dd" the old tz.mbn into /dev/block/mmcblk0p7. Attempted to reboot to see what would happen, and well, brick happened. So yeah, don't do that.
Anyway, is there a way to JTAG it back, or is my only recourse to use it as parts to fix a phone with a cracked screen or something?
Also, I'm not smart enough to know why it won't boot with a downgraded TZ partition. Is a hard-brick what happens when the "chain of trust" is broken? Could it have worked had I downgraded every single partition involved in the chain of trust, or am I super far off base?
What exactly do you mean when you say it acts like it has no battery?
Try hooking it up to the computer and quickly press all 3 buttons to get to the boot menu. If you can, go into AP Fastboot and RSD a stock image back to stock everything.

It pretty much acts exactly like a phone from which the battery has been removed. Dead as a doornail.
No power, no lights, holding buttons does nothing, plugging it into USB does nothing, holding buttons while plugging into USB does nothing. Can't get into AP Fastboot, nor do any USB devices ever show up to run RSD. Zero signs of life whatsoever.
Either make or buy a factory cable/adaptor .... Its.not hard to make or team black hat has them for $10usd
Sent from my XT907 using xda app-developers app
Just read up on them, I'm not sure if it'll work for me. Team Black Hat's twitter says it just bypasses the phone battery and allows it to be powered from USB. Sounds like it would mostly be useful for phones whose battery died during the flash. I might try it anyway, but my phone had 100% battery when I tried to reboot it.
Use it to flash the stock firmware... It should recognize the battery after that

http://www.droidforums.net/forum/droid-labs/146492-how-why-make-your-own-motorola-factory-cable.html
Verified +5V on both pin 1 and 4.
Nothing.
I think to get into AP Fastboot or even for the bootloader to launch, it probably requires an unbroken chain of trust and my downgraded TZ partition breaks the chain so it doesn't even try to start the bootloader. Just guessing though.
I've been searching around... Can't really find much to assist with this... You may be able to get some help from the higher up's if you message them...
Sent from my XT907 using xda app-developers app
Thanks for searching. I'll probably end up looking for a phone with a smashed screen on ebay and swap the motherboard. Maybe I could get lucky and find one that's never been updated, though I doubt that.
Can't help but wonder if I'd flashed every single partition involved in the chain of trust if that would have worked to downgrade. Dangerous thinking. I'd best stop thinking about it or I'll end up with another bricked phone.
After months of my phone being bricked, I decided to plug it into USB and the green light came on and it shows signs of life. No picture on the display, but it shows up as USB Input Device, shows as "HID-compliant" in device manager. Hardware ID is VID_05C6, PID_F006. All I could find is the VID belongs to Qualcomm. Any ideas?

Sorry, my Google-fu is not as good as yours. Searching for that VID and PID only comes up with an XDA thread on an HTC Unbricking Project in the Evo 4G LTE section. Google has zero hits linking either VID or PID with "RAZR M". Everything I've read about unbricking requires the phone to be able to get into Fastboot AP.
Tried Bing too, but my Bing-fu is worse than my Google-fu.

My problem is similar, but not exactly the same. I don't get "Qualcomm HS-USB QDLoader 9008", just "HID compliant device", but I know it's Qualcomm just from the VID.
At bottom of the thread is just a link to a JTAG unbricking service for $50. Is that the solution you're referring to?
If that's the only solution, I'll try a motherboard swap first. It's half the price.

I thought that was the same....
Not up on the subject. I know cellzealot is, on that thread.
The problem is that we don't have the signed images for the low level boot ram downloader for these models available to us.
I helped someone fix their hard bricked Moto X but we were only able to do that because the boot loader repair kits for that chip set were included in some of the leaked engineering firmware builds for those devices. Those kits have the bin and hex files and a .bat script that writes the images to the raw QC flash device that allows it to be enumerated as an Android fastboot device and flashed normally with signed firmware images.
Unless we get those repair kits or find all of those components in the wild, we can't recover these phones from a hard brick.
FIXED! But not in a "good way" that's helpful for the community.
I bought one with a cracked screen on eBay and swapped my screen onto it. The screens are still quite expensive for these phones (~$90) so cracked screen versions go pretty cheap. Paid $26 shipped for mine which is on the high-end, most went for ~$20 shipped but I'd miss the auctions for one reason or another. This one also was in nicer shape than mine which was worth the extra $6 to me. Although I later came to find out it takes a good deal of heat and force to get the screen out of the metal bezel since the rubber glue adhesive Motorola uses is DAMN STRONG, not like the 2-sided tape from my iPhone fixing days. Didn't want to risk cracking my good screen trying to swap it into the nicer bezel so I just swapped the entire screen/bezel assembly. Super easy.
Worst part, 98.18.78. BOOOOOOOOOOOO!!!
Oh well, nothing gained, and only $26 lost.
Any reason at all to keep it on 78 and not upgrade to 94?
just curious if anyone has played with qpst while in qhusb (?) mode i know the qpst software has the ability to flash to devices in this form of download mode if someone were able to recover a device with it then the next thing on my mind would be can we downgrade with it to a version that could be bootloader unlocked. i'd try it myself but its very risky to try on a device thats perfectly good. but perhaps... one with a broke screen or otherwise scrap would be perfect to mess around with
QPST didn't seem to notice the existence of my phone when it shows up as a "Qualcomm USB Input Device".
Part of it could be it won't stay on for very long, not even using the USB cable I bought that's supposed to be a Motorola factory cable.

I replaced the motherboard on my bricked hdx 8.9 also had to order a daughterboard as it was borked also.
I tested with the daughterboard from my wife's tablet.
Works like new.
Total cost was about $50 from ifixit
They are out of motherboards but I'm sure you can find one somewhere online.
With the proper tools and watching a few teardown videos on YouTube and some patience it's not a hard job at all really.
Hope this helps those out there that are stuck with a paper weight.
Be gentle removing the screen from the back, there are tabs on top and glue in the middle on each side. Don't just try to pull it apart, go slow and be careful.

You will likely need a daughter board too. Depending on cost it may be less expensive to pick up a used HDX 7 at an auction site. If you decide to repair no one can say if it will work or not as your situation may be different than others.

Mainboards include internal storage. So similar to starting with a new device or whatever the previous owner left behind.
Hmm...is there a way I can pull data off my dead hdx? Looking to get pictures off it.
Device is dead...tried all the soft and hard reboots, with charger, etc...just blank screen.
Trying to get a working hdx 8.9 off ebay for parts. Was thinking to try battery, then daughterboard, then motherboard...but it seems if the motherboard is the culprit, my data is hosed.
Hoping some way to hot wire something...mount it or something to get that data if possible!
Any advice?
Thanks

Identify suitable pad connections is above my pay grade.
Not sure anyone has had any real success with this approach. There was a flurry of activity early looking for boot exploits and ways to recover bricked devices. Also getting power to the USB port for OTG support. AFAIK nothing came from those efforts.

Thanks Davey,
Guess should save some money and accept the loss...will wait for the 2017 models to come out and get one of those.
Contacted a pro recovery place and they wanted 900-2000 to do the recovery!!!
Saw some wild post about sweating out the chip from the motherboard and solder it onto another one...wish I took those electronic courses all those years ago
Davey,
Thinking of doing something radical.
Do you or if anyone else wants to chime in, know if I get identical motherboard with same internal storage size, could I just swap out the storage chip from the bad motherboard and move it to the working motherboard, or are there other things on the board that would differ that would cause an issue?
Thanks

whoa! Pressure is on!!!
I'll give it a go in the next week or two.
I already got a working doppelganger device that I will start replacing components to see if anything else is truly defective.
If that doesn't yield any results, I got another scrap kindle off eBay to practice my IC chip removal process. It seems pretty simple and actually quite forgiving.
I will need to maybe get a more fine solder tool...one I got maybe too big of a needle...used it for soldering pipes...also need to get some removal items...but other than that...just need time, steady hand and lots of luck!!
If it is a success, I'll document the process and post it here, if it fails, I'll post as well and state what issues I came across for prosperity sake!

Other than that: I also have a bricked and a working HDX 8.9 here. I am wondering if I could just somehow dump the software from the working device and flash it onto the bricked one. Does anybody know how to do this or know if this would be possible somehow?

Other than that: I also have a bricked and a working HDX 8.9 here. I am wondering if I could just somehow dump the software from the working device and flash it onto the bricked one. Does anybody know how to do this or know if this would be possible somehow?

Unfortunately not possible (or at least practical) on a locked device. Even when unlocked 'bricked' HDXs are not easy to work with.
Heya,
It seems like my usb connector is busted (or the entire daughterboard. i'm not sure) but I'm wondering if anyone has had experience replacing just the connector?
The phone still charges via usb, but when i plug it in, it says that the USB device has malfunctioned and it won't connect to the computer. I don't know if this is a daughterboard failure or just a port failure.
i'm hoping to find a way to replace the part without having to remove the screen if it is even remotely possible..
any advice?
Thanks
It looks like you need to remove the screen to replace the USB port. The part is probably quite inexpensive and unless your soldering is extremely good then I'd just replace the whole thing. I did it in my Note 3, that was easy, but never done it on my Note 4.

yeah, my biggest worry is that if i have it done by someone, they would crack the screen and a $65 repair will turn into a $300 repair....
Device modified in any way? Knox tripped?.....If not then (in the EU at least) Samsung provides a 2 year warranty......
It *could* be argued that the usb port should be expected to last for the full 2 years at least......
Check your paperwork/warranty card and try for warranty repair.

have you try connecting it to another computer?
my 910H is acting like that too when connected with my home PC.
but if connected with office PC, no problem appears. It mounted well on windows explorer.
driver issue, perhaps.

I wish that was the case.

I know this is a silly question, but have you tried installing drivers before connecting?

yup. uninstalled the driver completely on 2 of the computers and reconnected. the moment i insert it, it says usb device has malfunctioned. it'll charge, it just will not establish a connection

lol i know. I'm still trying to figure out if I should do my own repair... or pay 50ish bucks to get it done by someone else...

So did you get it repaired already? I have exactly same problem on my N910C. Tried different cables, different pc, factory reset, reinstall driver and other possible fixes that I can find on the net but still can't get it recognized on pc. I sent the phone to some repair shop to replace the usb board but the outcome is still the same.
I've bought the phone as a used unit and straightaway updated it OTA to Marshmallow. It is possible that I got a bad firmware?

unfortunately not yet. I'm still waiting for the part to arrive.
I might pay someone to do it for me, but other than that, i'll have to just try my luck.
I don't know about firmware because my issue cropped up randomly and I've been on this rom for over 3 months. so i think it's more of a port or board failure.
One thing *might* come in to play with the replacement......
On both the S2 and the S5, there were/are several versions of the board for each device.....none of them are interchangeable.
If Samsung follows previous form, this may well be the case for the Note as well.

yup! indeed that was what was holding me up. I have the N910C and no repair shop in the US has that board, so i have to order it from China....

But....If it follows the Samsung pattern, there will be more than one version of that board for the N910C......
Going back as far as my experience with the S2, my device was the international variant, and i discovered that just for that one device, there were 4 different versions of the board.
They were....
REV1.2, REV2.2, REV2.3 and REV2.4....
I had to get the matching version otherwise it led to problems like reduced/loss of signal, otg failure, data transfer failure......The list went on and on....

oh if you're talking that specific, then no there's no problems that I know of about specific revisions.
If there was it would be all over ebay with different revisions of the boards.

Um....done a little ebay research and for the F variant, I've seen 4 different revisions (so far)........
0.6, 0.8, 0.9 & 1.8
I think getting the right one is gonna be critical if, as I said before, it's the same 'pattern' as with previous devices.....

I looked up the N910C variant and there's no revision.
and looking up the F variant.. I don't see any revisions as you said either: http://www.ebay.com/sch/i.html?_odk...+usb+board.TRS0&_nkw=n910f+usb+board&_sacat=0
I went into a random selection of listings and zoomed in on the images.....
The printing on the black ribbon cable is where I saw the revision information....
