I really fretted the decision of a new phone as my upgrade was from the Htc thunderbolt. I looked at the S3 it seemed ok but had a cheap plastic feel like I could break it by holding it to tight. Plus I dont care for touch wiz. Moto Razor maxx HD screen still has gray tint to every thing not as bright, dull colors as moto always had. And typical moto style. Thought both phones had good and bad as all do, when I looked the DNA at the big red store it was hands down the fastest phone I had ever picked up. screen colors beautiful felt better to hold than S3 or moto seems I forgot I ever had a TB was worried about no SD card but no problems yet and battery life is so much better than TB with extended battery I am truely a happy DNA owner hope you will be to

I would only switch to Tmobile if Carly Foulkes started dating me...lol JK! (she's the t mobile spokesperson)
[HTC Droid DNA] zone23:
The big question is what makes this phone any better then the rest? Well for me its really just a couple things. The first thing is I like Sense. Now people say well whats Sense? They are widgets designed by HTC. Some of them include the Weather Clock Widget that shows animated weather on your home screen when the phones unlocked. HTC includes bookmark, people, weather widgets all designed by HTC. Now you maybe thinking well weatherbug has widgets already (for example). Their widgets are crap in comparison IMO. That said I also like the wireless charging (cost 40 bucks for the charger). I like the LCD display looks fantastic. The phone doesn't feel like a cheap plastic kids toy. And that's all I have to say about that.
[HTC Droid DNA] nrage23:
What he said. I have done Motorola and Samsung before. They do not have the build quality in my humble opinion as HTC. Also Moto Blur and the Samsung UI are not nearly as polished as Sense is. Last thing for everyone complaining about the storage space. I bought a USB-OTG cable from Amazon to use with my Nexus 10 and it also works with the DNA even in TWRP I do my backups to it. You can plug a thumb drive or I use a very small MicroSD adapter with a 64gb card.
[HTC Droid DNA] aFancyTickler:
S-OFF

well the dna has s-off now! so that makes this phone even better with custome hboots and radio.imgs
[HTC Droid DNA] softBrikt:
I debated the DNA/Note II/GSIII. I went in to Verizon and held each one and used each devices specific features and I ultimately left with the DNA here's why:

Everything about this screen is incredible (5", 1080p) and it's no bigger than my GNex

I wanted to use the S-Pen and it's features, but after playing with the phone for a few minutes in the store I realized it wasn't practical... to me.

HTC, in my opinion, makes quality phones and support their hardware.

GSIII is an older phone and, while still a very solid device, has already been surpassed specwise by phones like DNA and Note II

I love the wireless charger from Nokia (purchased through Verizon for a discount). No BEEPING and works like a charm.

Devs have shown it some pretty decent love since it's debut

Good luck!

Wtf...

Not a lot of us base our phone purchases on the chances of being trapped under a building..

Its free to get into the us right now. Come on over and get u some of this Internet :)
[HTC Droid DNA] Tybaltus Prime:
i have been from incredible to Droid x, to droid bionic, to gnex to DNA.

gnex rules, but we all know why. at least we should. if we do not. please do not comment. The DNA build quality and radio strength is leaps and BOUNDS. seriously. the screen is beautirul as well, but we all know all the phones will have 1080p soon, so i dont consider it a factor. If you like ur phone stock, then (i dont know why you are here), but you will be more than satisfied. Software is the biggest dissappointment here. I am hoping to see sense 5 here becasue all iterations previous i DESPISE. However, we are unlocked, rooter, and s-off and noone thought we'd be unlocked. Dev is definitely there and moving, so i feel the software side is just getting started. STOCK software sux ONLY if you want openness. Otherwise the phone is beatiful, looks and feels great, takes great pics, and has impressvie battery life especially given the size screen and processor. if you are here for the benefits of root, and open source loving.. GNOTE2... or something... sorry for the ramble.. im at work and hurrying
[HTC Droid DNA] nrage23:
Please stick with Samsung if you do not like Sense. People either like Sense or not at least with HTC phones you have the option of Sense or eventually AOSP where as with the Gnex you have Aosp only. I am personally a huge fan of HTC for build quality and Sense. I done have Motorola (Bionic) and Samsung and have no interest in ever going back to either one for a phone.
[HTC Droid DNA] famous145:
Well I had the htc droid eris awhile back and liked sense on there but never had a Samsung phone yet
[HTC Droid DNA] rfarrah:
The ONLY reason not to get the DNA over any samsung phone depends on your need for additional memory. Battery lasts over 24 hours for me (med-light use) and everything else is perfect. But if you NEED a lot of extra memory for music or games or whatever, then you may need to reconsider.

Odp: [Q] Qauestion about flashing stock rom

The easiest way would be rooting, installing cwm, backup with cwm of your stock rom, than flash custonexus. When you want go stock, you restore system from backup and eventually unroot.

Why would you post a random post with 2 codes and zero details which requires a Google search to understand what you are asking and then expect a reasonable response?

The code is for the Nexus docking station BTW. It took a search to find out.
[Nexus 7 Accessories] jonnyg1097:
I would assume it has something to do with the country/region the dock is being sold in. I say this because for the Samsung Captivate, the Canadian model was the i896 and the American version was i897.

Or I could be completely wrong.

Hello lovely people.

Not long ago, my wonderful Samsung Galaxy S2 dropped dead. Before I send it in for service, I would LOVE to get the data on the internal storage back.

The phone does not get hot while charging, and nothing else whatsoever makes it show sings of life.

Is it possible to swap out the internal storage chip from the motherboard, and place it on an another identical phone, and retrieve the data that way?

Any sort of tips for businesses that would do something like this is welcome!

As you can guess, I learned to back up my stuff the hard way. My last clockwork backup was 20 days ago. Precious 20 days ago :(
[Hardware Hacking General] psytr0nic:
probability = 99,99% yes ... a SD-card no matter of where it was before. have good luck
[Hardware Hacking General] gl3nborj:
And the deadly .01% is if the damaged part is the internal memory itself.

:good:
[Hardware Hacking General] Rebellos:
While emmc chip got like 20 important pads to solder (out of even hundred, when most are there being N/C) it is still BGA. A ****ass small BGA covered with glue. That would require someone really experienced with reworking such things. I do not know the prices but I would be prepared to pay even 100$ or more for such job, done right.

That from HW level. From SW+HW look: in theory there should be no trouble with properly swapped emmc ic from other phone. But you shall not forget about the said 0.01%, maybe more - reworking such chip might have influence on its content (I might be wrong) + GS2 had the emmc hardbrick bug - how did it die?

Please let us know how did it go.

Oh and btw - there must be companies working on such data recovery with proper HW to wire up to the unsoldered chip with sort of socket or other hackaround - I'd lookup there.
[Hardware Hacking General] E:V:A:
Max specified operating temperature of an eMMC is about 85 °C, there's no telling what happens above that... So whatever way you use to re-connect your eMMC, make sure it is not by soldering!
[Hardware Hacking General] NiTrOwow:
Of course it is possible but you need highly expensive tools for it to solder of the chip. it is BGA it's not just like a transistor..

It does have hundreds of micro balls under the chip. Did you try adb shell already? Or is it really 99% dead.

You may find a company that can do it but it will cost A LOT of money. Because you need special tools for it.

Something like this

You best bet would be to try to use a heat gun on the main board. Just heat it up for a few seconds and cool it down to zero as quick as possible. Maybe the bga is cracked because it got hit by the ground when you accidentally dropped it. By heating it up you may temporarily fix this crack(will also cause slightly damage to the chips) in the soldering. So you can back it up and sent it back. I think it will void the warranty, but you have to decide for yourself what to do. Try to get back the data or get a new working main board from Samsung (if you sent the phone back they will just replace it with a new one most likely).

Bga soldering crack
[Hardware Hacking General] psytr0nic:
0,1% of chance .. playing with Samsung EMMC chip = bye bye phone . look around forum or elsewhere 100% of bricked is due to it .

Question : what make you confident to say that your internal memory is good ?

to remind : it is also your phone flash chip which manage boot sequence and all . don't forget it .

every time I tried with hot air , I removed chip with missing pads cause of glue under chip which make hard to remove .

why not to give a try ? have good luck
[Hardware Hacking General] NiTrOwow:
Those are options you have instead of paying hundreds of euro's to a company that can recover it if it isn't the nand/emmc itself that is the dead part of the phone.

Of course i recommend him to go to a professional company and let them do recover it. Because they will do it the proper way but like i said before it cost you a lot of money.

So your best bet would be to try it yourself or just sent it back to Samsung for warranty.(by trying yourself i don't mean to solder it off because thet will not work out good. It will probably kill the chip, just try to reflow the mainboard and maybe you have luck.)

I know about glue in the corners of bga based chips in HP & Acer and other brands in laptops and such but didn't know that phones had that too.

But glue under the chip, never seen that before. And btw you cannot remove a bga soldered chip with a heatgun you need ir so that the whole surface under the chip gets loose. And you need to cover up all other components or they will get loose too or fry :)

Acer bga soldered chip -> glue in corners (this is not nand or emmc, its the chipset & cpu/gpu)

Recovering data from snapped Galaxy s2 motherboard

Hi everyone, i really need some help

My galaxy s2 motherboard has snapped (around the long thin bit) with all other parts of the motherboard still intact. I really need to recover all of the data. The data has sentimental value and cannot be replaced. Is there any chance of recovering the data either through chip extraction and onto new board? Can the existing motherboard be fixed?

All i keep hearing is that it is too difficult, the motherboard is multi-layered and would be impossible to fix. I am reluctant to take this as an answer. Is there anybody out there that has a solution for recovering all the data? Who would i go to? who do i pay? Ive contacted samsung and they say it is impossible, when questioning them why it is impossible they state tit would cost too much and they cannot do it.

Please help. thank you.

EMMC reball and some other tips

Hey guys,

I know this thread is a little bit old but I'll try to give in my 2 cents maybe someone here may find it helpful :)

So I come from background where I do around 20 bga reballs per week, so I do know a thing or two I guess about this although my knowledge on Samsung platform is relatively low compared to an iphone logic.

So to begin with replacing the emmc chip alone is not enough as you'll need a programmer box which connects to a jtag interface which is able to rewrite the initial files like bootrom to the emmc. You can find these boxes at any prominent gsm repair shops; boxes named such as RiffBox or Z3X Samsung box are the best I found recently.

Having said that before any repair is attempted by mainly removing the flash chip it is imperative to try to resurrect the phone using these said boxes, to try to find whether or not the NAND chip is actually detected. As one may have simply installed a ROM which is not compatible with the phone and all that is required is to rewrite the bootrom files. If the NAND (basically the same name as a flash chip) fails to be detected then obviously something went wrong and it either could be the NAND is burnt inside, or the NAND has some cracks under its critical ball pins or even may be a problem that the main power management chip inside the phone is failing from supplying usually around 3V to power up the NAND.

The emmc chip at least found in a samsung is a 14 by 14 pins which only about 1/3 of it's pins are critical, the rest are dummy and do not worry if they eventually get removed, while removing the chip or cleaning the board after desoldering prior installing the new chip.

Some tips on reworking:

Always cover critical glued components like CPU + POP (package on package) RAM, baseband processor usually XGOLD found in Samsung.

Clean surrounding chip glue before attempting to remove by giving around 250C of heat and with a needle scratching the glue around

Do not exceed more than 350C to remove the actual chip to prevent more damage to the built in tracks inside the motherboard.

Last and not least a schematic for your phone would always be a lot of help to help you detect what voltages are missing on bootup to make sure that the boot up sequence is starting fine and also the relative points of each pin under a chip while knowing which pins are critical and which are dummies, or NC (not connected)

If you need any help you can always message me and I'll try my best to answer your questions.

Regards,

Ryan

solder with care

Solder with care mate, else it will be totally gone :rolleyes:
[Hardware Hacking General] AnArChYm:
The glue in samsung is very easy to remove you just need to heat the board up to 250C and gently scratch the glued area with a needle. Do not worry on the removed pads as 1/3 of the pads under the EMMC are not connected and therefore not needed. Always clean the chip from the glue and use leaded solder for best shiny connections.

You will need special programmer boxes like riffbox to be able to rewrite the bootloader. JTAG is a dedicated space on the board where the riffbox will communicate with the phone.

Would like the learn how to reball

Hi Ryan,

My son's galaxy s3 i9300 was inadvertently given a spin in the washing machine. When I realised what had happened I took it apart into its various components and put it in rice for a week. When I switched it on everything worked except the cell phone signal. From what I can gather the eMMC chip has been damaged and no software can fix it. I don't have it with me now but I think IMEI and baseband is unknown. The EFS folder is empty or corrupt.

Stumbling across your post I was interested in the fact that you seem to be an expert in re-balling. My son has since got a new phone and since I am a basic amateur in phone repair (for family and friends) I have been toying with the idea of replacing the eMMC chip on the s3 after watching this video:

http://www.youtube.com/watch?v=s38vQxXv0GE

I don't mind if I buy the chip and it doesn't work I am more intent on gaining the experience and going through the stages. Do you think this is a good idea and do you have any tips or things I can research on the topic?

Data recovery - Siemens A31

Hello everyone,

this thread seems to be what I've been looking for. My Siemens A31 got some water from a torrential rain while it was on. When I got to removing the battery, the phone was already off. I dried all accessible parts but I did not have the necessary torx screwdriver, so some water stayed inside. It was Friday evening and I got the screwdriver no earlier than on Monday. There was some corrosion in the phone, of course. It could not be turned on and subsequent cleaning with alcohol and even ultrasound improved only the look of the main board, but not its behavior. :( The only sign of life was that it seemingly recharged the battery while connected to the charger.

I have asked several repair services and people and I am quite confused whether it is possible to recover the data by soldering the memory chip into another A31, a functioning one of course. Last time, I asked a laptop service and I was told it is impossible, not just because of the difficulty of soldering a BGA chip. They told me it would not work because the phone would get blocked due to IMEI mismatch! This was surprising for me. If it is true, it implies that the IMEI is stored in both the flash memory and some other chip. I was unable to find any evidence for such a claim on the Internet. :confused:

Can anyone tell me if the target phone with replaced flash memory will actually work, assuming the memory is functioning? The video referred to by yiannos50 suggests it may really work. Anyone else has tried it? Two people in this discussion were about to do so.
[Hardware Hacking General] AnArChYm:
Each phone brand is somewhat different but I'll comment on what I know. iPhone uses 2 chips to match an IMEI namely the baseband CPU and a serial flash IC, if the IMEI do not match than the phone would not be able to activate or do any radio related activity such as calling, sms, gps, wifi. Samsung on the other hand uses both the baseband CPU and eMMC ic again if a mismatch exist the radio activity will fail to work.

This is done in order to secure the phone, as you may know the IMEI is the unique ID that a phone can have.

With regards to your query, yes there may be a need to match between the NAND of your device and the main applciation/baseband cpu (since in older phones, these cpu's where combined as one due to less complexity in electronics). However being that the IMEI does not match one can still take the data from the phone's NAND chip as these are completely different sectors and electronic lines. In fact to restore the boot sector of a Samsung either due to bricking the device or maybe chip failure, writing directly to the eMMC chip one does not need to have the radio firmware online.

If you are willing to repair the phone I may be able to investigate it for you and look for the possibilty to repair the phone for you. If you're interested pm me.
[Hardware Hacking General] PepaLogik:
Hi AnArChYm,

thank you for your reply! Before possibly PM-ing to you, just a few supplementary questions:

(I suppose the "NAND chip" is a synonym for the "flash memory chip", right?) I do not understand in what way the data could be read. By just turning the phone on and reading them normally (on display or via cable), or by using some special equipment only?

I have already downloaded the technical documentation of this phone. The CPU has a JTAG section but I can find no JTAG connector on the board - there are just some contact points. Could these be useful even in the "dead" phone (i.e. without moving the memory)?

In addition, I have just noticed that the flash memory is combined with SRAM on the same chip. Do you think this decreases the probability that the chip survived the accident?
[Hardware Hacking General] AnArChYm:
Yes NAND is the flash memory. It is not called NAND in this case as it combines the RAM rather than a POP (package on package) like nowadays phones. But yes that SRAM ic also has your personal data on it, possibly even the IMEI too to match the baseband ic, like discussed earlier.

As you have said yes there is a JTAG connection directly with the CPU with several testpoints which according to my knowledge enough to hook it up if it is enabled by the jtag controller to read addresses by a programmer box (like riffbox) however you would need to know additional stuff like start address offset and length of the memory to be able to extract your relevant data.

I guess at this point in time the only available option for you is to repair the board, reball the corroded ic and hope for the best. Luckily the phone's board does not look complicated with just 3 main chips, namely, Power management, baseband cpu and 128MB SRAM.

Let me know.
