[Samsung Galaxy S7 Questions and Answers] Alex.NoName:
Hi all!

I have got a strange problem on my smartphone Samsung Galaxy S7 (SM-G930F).

The network connections (WLAN and HSPA/LTE) starts with normal speed and crashed after a few seconds. Sometimes it cames back for only a few seconds again. (In Google Play Store I got 491/495-error.)

I tried all the known work-a-rounds like resetting network, clear cache, wipe cache/dalvik, factory reset, installed orig firmware again etc.

The reseller and the samsung support couldn't find any problem (or better any solution).

So I decided to install the latest LineageOS 14.1 (Android 7.1.2) from 2017-11-07. But the problem still exists.

With aLogcat I couldn't found any hint.

After installing F-Droid store and trying to install an app, I got error messages like this;

Read error; ssl=0x7f8c3c9440; Failure in SSL library, usually a protocol error

error; 1e000065;Cipher functions;OPENSSL_internal;BAD_DECRYPT (external/boringssl/src/crypto/cipher/e_aes.c;1187 0x7f9b150e7e;0x00000000)

error;10000008b;SSL

routines;OPENSSL_internal;DECRYPTION_FAILED_OR_BAD_RECORD_MAC (external/boringssl/src/ssl/tls_record.c; 221 0x7f9b150e7e;0x00000000)

hypertext secure link to fdroid pakage fdroid_1000011.apk

(the memory addresses in the error message may change/all semicolons are colons in original and I had to remove all hyper text prefixes because of restrictions for new users)

Next I tried to change the WLAN-MAC-address. because of the MAC hint in the error message. But nothing happens. The problem still exists.

ps; Surfing webpages seems to work without any problem. Maybe it still exists not before big data is requested.

pps; On faster network connection more data received before the problem comes up.

Thanks for your advices!

Hi!

A little update:

bigger downloads even over the hypertext-secure-protocol from firefox works without any problems.

Seems that all software using the boringssl-lib from Android doesn't work. Downloading the amazon app store worked perfect - starting the app and logging in does not.

[Samsung Galaxy S7 Questions and Answers] Alex.NoName:
Hi again!

Hope all of you have nice hollidays.

I'm sure right now, that it must be a problem between the modem and the boringssl library.

But I coudn't find a way to report a bug to the boringssl project.

As it is part of Android project should I report it to them?

I think the reseller and Samsung are really interrestet giving a solution to me.

Thanks and happy holidays!

hello

i need help

can anyone unlock spv E650 ??

please say something

thanks
[HTC Vox] tobbbie:
There are several sources for unlocking:

first contact the operator where it locked to, some give the code for free (T-Mobile Germany.

contact jockyw2001 here for reasonable offers (usually cheaper than commerical sites)

compare prices of unlocking services and the way they work. The most complete unlocking comes form the guys at http://www.imei-check-uk as they also CID unlock the device (check with them to be sure).

Hi,

My wife has broken the screen on her S6 and as a result it is completely dead. She now has a new phone and I've managed to connect to my PC to get all her old photos off.

However, I was hoping to sell it for spares or repairs with the dead screen but was wondering how I would go about clearing any personal information off it.

Do I have to delete all the necessary files off individually and of so which ones? or is there software that will do it for me.

Any help with this would be appreciated.

if you get an mhl cable you should be able to connect the phone to the tv and use that as your screen but only if the screen still responds to touch failing that use the samsung smart switch software and do an emergency firmware recovery I think that wipes your phone.

[Fire TV Q&A, Help & Troubleshooting] rdpdo:
Thanks you for the links... but the links above are for TV stick v1 not for TV stick basic edition.

Anyway, I will post there.
[Fire TV Q&A, Help & Troubleshooting] iLLNiSS:
I'm also looking for the eMMC pinout on the basic. From what I've read, it's the same as the FireTV Stick 2nd Gen, but even that I can't find pinouts for.

Here are some board pics for the Basic.

UPDATE: pic updated with pinouts as I find them.
[Fire TV Q&A, Help & Troubleshooting] iLLNiSS:
UPDATE: It seems as though the difference between the two chips may be more important than I had previously thought. The PD/ZB is the package code, and comparing the MT29TZZZ8D5JKEZB-107 W.95Q to the MT29TZZZ8D5JKETS-107 W.95Q it would appear as though the BGA is completely different (168 pin vs 221, layout also being completely different). I may just have to donate this FireTV basic to the cause and lift it. If i'm lucky my BGA rework skills are still half as good as the Xbox 360 days.

Did a bit of digging, and it seems the markings on the eMMC do not simply reflect any internal models of the chip (as evident by a simple google search), but luckily Micron has their own decoder you can use.

The chip beside the ARM CPU appears to be an eMMC/RAM combo unit. Searching their site I cannot locate anything for MT29TZZZ8D5JKEPD-107 W.95T specifically, but there are some that are very close, like the MT29TZZZ8D5JKEZB-107 W.95Q. The difference between the chips is one has 8GM RAM the other (which I can't find) is the FireTV Basic which has 1GB ram.

Regardless, it looks like we're gonna have to pull the chip to determine where the required BGA pins can be accessed externally as there doesn't appear to be anything close to the eMMC. My guess is the underside of the board will be where most the pins will be accessed (hopefully).

Data sheet can be found here

And below is a cheat sheet:
[Fire TV Q&A, Help & Troubleshooting] iLLNiSS:
My SMD rework station came in (needed a new iron and was sick of heatgunning BGAs) so I put it to use right away and lifted the eMMC/RAM BGA.

Lo and behold, my guesstimate appears to be correct.

It would appear as though the MT29TZZZ8D5JKEPD-107 W.95T layout matches that of the board.

I unfortunately lost my bottle of rubbing alcohol so couldn't clean up the board for better pictures so this will have to do for now. Hopefully I'll have some time to trace some of the required pins in the near future once I get some more rubbing alcohol. CMD/DAT0/DAT5 can be visibly traced to outside the chip, the others will require manually mapping across the PCB for alternate locations. But for now, this is looking promising.

It's also worth noting (I picked up another FireTV in case I can't reball this one) that the one I just lifted the BGA from was a Samsung eMMC and not a Micron like my first FireTV Basic. Of course though, the datasheet is not available so I will work from the pinout in the MT29TZZZ8D5JKEPD-107 W.95T as planned.
[Fire TV Q&A, Help & Troubleshooting] rdpdo:
Thanks you it's really a great work !
[Fire TV Q&A, Help & Troubleshooting] iLLNiSS:
Well guys, I'm trying to interface with the eMMC by dead bug (pulled BGA, wired it to the exploiteers low voltage adapter but I'm not having any luck. Can't seem to find any issues with the wiring, but she just won't recognize in the computer. Anyone got some hints/ideas?
[Fire TV Q&A, Help & Troubleshooting] goalguy10:
iLLNiSS do you have the pinouts? I have the same device and would be willing to try.
[Fire TV Q&A, Help & Troubleshooting] iLLNiSS:
Negative. I took a break after the dead bug method came up empty handed for me. I suppose I can trace out the points still and someone else can try without lifting the BGA but I wouldn't make any guarantees.

Keep an eye out here in the near future. If I get around to it I'll have them posted here right after, I'm just busy with other projects and work.
[Fire TV Q&A, Help & Troubleshooting] pd_ace:
Hey guys,

I opened also my fire TV stick (2nd gen) that shoud be the same like the fire tv stick basic and found the same layout of the board as shown in the picture of iLLNiSS.

The emmc on my fire tv stick is made by SK HYNIX with the part number "H9TQ64A8GTACUR-KUM".

I didn´t find the data sheet for this emmc. However, I found the data sheet for "H9TQ17ABJTMCUR" that has the same dimension but 16gb storage. In this data sheet there you can see that the pinout is the same as found by iLLNiSS. So we are heading the right direction.
[Fire TV Q&A, Help & Troubleshooting] goalguy10:
You get a chance to trace the points? I have one with the chip still on it I would be willing to try.

[Fire TV Q&A, Help & Troubleshooting] iLLNiSS:
Well, I'm back!

Sorry for the delay, I mostly lost interest due to taking on a new position at my company.

So, good news! I've successfully communicated with the eMMC. I was having the same issues as I mentioned previously, and was about to give up when I traced some voltages while the MMC was plugged into the reader and it came alive. Not sure why, but I'm not complaining. I can confirm that the cheatsheet pinout I previously posted is correct.

Currently setting up a linux distro again so I can dump the contents. Hopefully all goes well!

If anyone who knows what they're doing feel free to request the dumps. Maybe it could help with a non hardware root.

UPDATE: So it wasn't dumping the partitions fully (kept failing randomly) and now it's no longer reading like it was before. I suspect there is too much interference so I may try shortening my wires (they are only like 6" long). So for now, all I can say is the pinouts are accurate.

UPDATE2: CLK pad ripped up as is tradition! Looks like I'll have to look at tracing again. Sorry folks!

Please refer to this post for pinouts. I will be adding them as I find them. https://xdaforums.com/showpost.php?p=74633569&postcount=4

Have you tested this with an emmc adapter?

I suppose you have to desolder the clk resistor, in order to stop the SOC from booting?
[Fire TV Q&A, Help & Troubleshooting] oktay50000:
you have to pull the emmc to use in the adaptor , if your micros soldering skill is good then you can do it without removing the resistor by using thin wires if not ,remove it program the emmc and then solder the resistor back ,its better than removing the ic itself lol

Ok, thank you.

Yeah, I have the low voltage emmc adapter from exploitee.rs, had it connected to the first generation stick and the first generation firetv.

[Galaxy S 5 Q&A, Help & Troubleshooting] VoltexYT:
Do I need a new battery for my Galaxy S5(kLTE)?

Below are some details about my current phone & battery, Please help me determine if I need a new battery or not

Phone Age: 3 years

Rom: Lineage OS 14.1-20170823 (Android 7.1.2)

Battery Capacity: 2800mAh

Charge time(to 100%): ~3 hours

Time able to use from 100%: can full use total 2-4 hours. When idle, the battery will still drain(even with bg apps closed)
[Galaxy S 5 Q&A, Help & Troubleshooting] Many40:
2-year-old phone and you can use it max for 2-4 hours only? :confused:

My phone is 3-year-old and with light usage on stock firmware I can reach about 3 days.

It seems that you are facing unusual wakelocks on your custom firmware which heavily drains your battery.

I would recommend you (before deciding to buy new battery) to do following:

1. Install one of the available battery monitoring apps. I recommend BetterBatteryStats:

https://xdaforums.com/showthread.php?p=15869868#post15869868

2. Read carefully the instructions/help

3. When you get some knowledge about battery overview and wakelocks -> analyze the results from the app by your own and try to find a cause for your problem or

4. Make proper dump file from the app and post it on the BBS thread asking for help.
[Galaxy S 5 Q&A, Help & Troubleshooting] VoltexYT:
Thanks for your help! I will try this later today :)
[Galaxy S 5 Q&A, Help & Troubleshooting] Oswald Boelcke:
I can only second what @Many40 stated in the valuable post above. I'm personally using BBS.

Idle dumps should be taken after a full charge and unplug for at least six hours. Don't touch the device during the time at all. Screen-on-time must be less than one minute i.e. after the at least 6 hours, turn on your screen and immediately get the dump.

Here you find a slightly different but even better procedure by @Davey126.

Final remarks as they could provide some benchmarks:

- Fully charge then turn off the device completely and let it rest for e.g. ten hours. Turn it on and check how much the battery lost during this time frame having in mind that the device used some juice to power up. Obviously, you will never be able to get less battery drainage than that you experienced during this test.

- Secondly, conduct the procedure from the very top but with the device in airplane mode. Again, you'll never to be able to achieve less drainage than during this run.
[Tilt, TyTN II, MDA Vario III General] cinguliano:
I need some special help here, please.

In older PPC models (Cingular 8125/8525 and Sprint PPC 6700), it was possible to type accented characters by pressing the unaccented character and then holding down Fn and pressing Spacebar until the desired character was displayed. On the Tilt, the Symbols keystroke has been changed to Fn+OK (I can live with that), but now instead of cycling through the relevant accented characters, we get a SIP full of irrelevant symbols and we have to scroll until we find the desired one.

This new method is inconvenient for those of us bilingual folks who frequently type in a non-English language, but more important, this method is not compatible with screen reader programs for the blind, as keyboard focus remains on the document and the user is expected to tap symbols via the touchscreen.

I've read somewhere that the TyTN II uses the old-school method (Fn+OK/Sym) to cycle through the relevant accented characters. Short of reflashing a Tilt with a TyTN II ROM, is there some registry setting we can tweak to get the Tilt to use the traditional symbols behavior?
[Tilt, TyTN II, MDA Vario III General] cinguliano:
BUMP. Anyone? Please.
[Tilt, TyTN II, MDA Vario III General] pdtp:
yea i would like to see this happen too. it annoys the hell out of me when im typing in a web address and i try to do it the old school style to get my forward slash
[Tilt, TyTN II, MDA Vario III General] cinguliano:
Figured it out.

HKLM\Hardware\Devicemap\Keybd

Setting for the value CWSLayout should be changed from 1 to 0.

This sets the Tilt to use the keyboard layout of the TyTN II, which means some symbols have different placement. I'm OK with that as now I'm happily typing on my Tilt's QWERTY keyboard without language constraints.
[Tilt, TyTN II, MDA Vario III General] cinguliano:
The forward slash / is Fn+R on mine. It was before I made the layout change and it still is on the same place.

[Samsung Galaxy S7 Questions and Answers] Tim2790:
I've been asking people online about this, but still have not found the fix.

It would be better if you try doing the following to rule out the issue if there is any.

My s7 is connected to wifi. When I walk far enough to lose the connection and return to the place with the wifi connection, it does not automatically reconnect unless I turn the screen on.

I investigated it using "web.whatsapp" on my laptop in which a connected-to-wifi s7 is required in order to use whatsapp services on my laptop. Unfortunately, I can't use such services because my s7 is not connected to wifi and i have to turn its screen on first to reconnect.

What could be the problem? Is it the router? or my phone? what should be done? I'm desperately looking for the fix.

I'm in Vietnam now. Thank you.

Probably Doze related
[Samsung Galaxy S7 Questions and Answers] Tim2790:
Really? My goodness! I don't think this phone is supposed to work this way. It causes notification delays especially if you leave the phone's screen off for a long time. It seems its radios stop scanning for a signal until we turn the screen on.

Are you really okay with this feature? How I wish we could do something.
[Samsung Galaxy S7 Questions and Answers] *Detection*:
Doesn't really affect me because if WiFi is disconnected I am on 4G data, so I still get notifications etc

Think it was the same on my S5 too

Make sure in WiFi > Advanced > Keep Wifi on during sleep is enabled, but I don't think this is the cause as WiFi is still turned on, just not reconnecting

Doze is likely the cause, AOD might help as it seems to break Doze
