[General Questions and Answers] Tawsif999:
Okay, First of all requirement-

A portable sd card- Because after flashing twrp, you might face issue where you can't access internal storage from twrp. That's because the phone might be encrypted. You have to decrypt it by flashing a "disable dm verity- forceencrypt.zip". In this case, you might not be able to transfer files from pc when booted into twrp. So, It's a smart move to insert a sd card containing all required files before to avoid these problems.

Another requirement is samsung drivers installed in pc. I will attach that file.

Follow these steps -

1/Unlock bootloader -Go to developer options. Turn on oem unlocking. It will tell you that you're going to loss all data. Proceed. If it doesn’t tell you anything, then there is definitely some extra process to unlock bootloader of your device.(search on internet)

2/Download your phone's official firmware in pc- it will help you if anything goes wrong. Search " Sm fw" on google. Go to first site. Create an account. Search the model number, Download a firmware that matches with all your device's information in "About phone".

3/ Download the lineageos rom and twrp recovery for your model. Then install device info hw from play store to check bits(32/64). Search open gapps. Go to the website. "arm" is for 32 bit & "arm64" is for 64 bit. Select which matches to your device’s bit. Then select the android version of the custom rom. Then select "Pico". Download the file. Next, download latest magisk 25.2 from github page. Rename the apk file to "magisk.zip" Move rom,gapps, magisk.zip to SD CARD. Keep twrp in pc.

4/In pc, download latest odin software. It's an special software for samsung download mode. (There is no fastboot mode in samsung)

5/Boot your device into download mode. And connect with pc.

6/In pc, extract the twrp file(If It's in zip format). Open odin software, Go to options, turn off auto reboot. Now select "AP" & select that extracted twrp file. Click open. Then hit start button.

(Note that most of the samsung devices can't boot stock rom after flashing twrp. So you have to flash custom rom to boot your device. Follow the next step)

7/Boot into twrp wipe>format data>type "yes". Press home button. Install>Select storage>SD card>select the rom.zip. Then add more zips> select the gapps.zip. Again, add more zips> select magisk.zip. After all, swipe to flash.

After installation, reboot device.

What if anything goes wrong?

Extract the stock firmware that you downloaded from sm fw. Connect device in download mode. Open odin, select AP,BL,CP,CSC file one by one. Start flashing. You device will be alive again.
[General Questions and Answers] joshtb86:
I've been increasingly looking into this option as I have an extra line on my phone plan and I have been looking at using a tablet on the line instead of a phone. This is through T-Mobile. There's been tons of stuff about people doing this years ago but nothing recently. Most carriers sell separate tablet plans that are cheap but provide very limited amounts of data. I've seen in the past solutions such as altering the IMEI number, build.prop changes, or using an international unlocked tablet.

Any idea where to start in 2022 Trying to get this done?

Thanks!

Altering the imei number can and will land you in legal problems. Never ever attempt such thing.

[Google Pixel 6] draexo:
I recently did a reset on my Pixel 6. When I signed into my Google account, it would not restore from the backup (though it is there), saying something to the affect that there were no backups. Now, Google Drive shows 2 backups for the phone. 1 from immediately before the wipe, and the new one it has made. Is there a way to restore the backup I made immediately before the wipe? Somehow, Google does not think it is associated with this phone, but it is.

[Sony Xperia XZ2 Questions & Answers] Atlax01:
I know there was many problems when Android 10 came out to this phone, but since then a lot of time passed, I guess there was some more updates to it. Is it worth upgrading the phone now? Is the latest 10 working just as fine, or better than the latest Pie?
[Sony Xperia XZ2 Questions & Answers] blackhawk:
Nothing wrong with Pie and security simply isn't a issue. It's the last good OS version before Gookill went insane, again.

I run two stock Samsung N10+'s, one on Android 9, the newer one on 10. The Pie variant runs best. There are over a hundred new system apps added to 10. It's a mess and 11 is even worse.

[8525, TyTN, MDA Vario II, JasJam General] Capt Fiero:
I just got off the phone with my cell phone company, I was calling in an unrelated matter about Road Side Assistance packages and I mentioned upgrading, they are willing to give me an HTC Touch Diamond for $99 bucks.

It has the built in GPS that I want, but no expansion slot. It has a better screen and faster CPU and better memory, but the screen is still only a 2.8 which is the same as my Tytn.

Whats your opinion on the Diamond vs the Hermes (Tytn)
[8525, TyTN, MDA Vario II, JasJam General] ultramag69:
The diamond beats the Hermes mostly due to the increased ram, g-sensor and GPS. I prefer the Hermes ability to use a micro sd but most people wouldn't use a lot of memory. Just make sure you are getting the 8Gb diamond, not the 4Gb,which is all I've been able to find in Oz.

You also don't get the slide-out keyboard but then, that makes the Diamond thinner than the Hermes by 1/2.

Personally, I'm gonna stick with my Hermes until the touch pro comes out here in Oz, probably in 2 or 3 years time..... :/
[8525, TyTN, MDA Vario II, JasJam General] Capt Fiero:
Thank you for the info, I spoke to them a couple days ago, and have not called them back to say that I want it. The no SD card kinda ruins it for me. I have 6gig now and am stuffed even carrying a spare 4gig card. I was going to pick up one of the 16gig Micro SD HC cards this month. I think the 4gig phone would be useless and the 8gig would barley be worth it. Even for 99 bucks I don't think I am going to take the deal.
[8525, TyTN, MDA Vario II, JasJam General] ultramag69:
I like the look of the touchpro better, it does support the sdhc and has a large amount of memory in it already. I also like the slideout keyboard as I've had my digitizer stuff up. Makes life easier if you don't have to rely on the touchscreen.

[Xiaomi Mi A3 Questions & Answers] ClaudiaS0fia:
Hi,

Sorry to put a new topic. If it's not allowed, delete it please.

I have a Xiaomi Mi A3, but i'm tired of the One Ui.

I've already tried MIUI 13 but it still has a lot of bugs and i don't know where i could find the rom updates.

I used EvolutionX, but it also has some bugs and didn't even have a camera app.

I've already put on Google and Youtube, which would be the best rom, but there are a lot of suggestions for roms and i'm not sure which one to use.

I wanted a rom with updates too and i give importance to the camera, especially the front one, so it would have to be a rom with a native app or someone who could point me to a good app without leaving the quality of the photos to be desired.

Thanks to anyone who can help.

[Mogul, XV6800 General] ygohome:
vx6800? or xv6800?

sounds pretty bad if you can't even get to the system - connections - connection app.

I'd suggest backing up your contacts etc... hardreset... or reflash the original vzw rom/radio.

then *228 option 1

you'll have to reauthenticate probably by calling vzw but that is simple and they are nice to work with.

Then you'll have to re-enter your network connections userid and password.

it's usually your phone# followed by @vzw3g.com

password is "vzw"

Then in the same phone call, ask vzw to reset/update your phone's IP settings from their end.

Then restore your apps and contacts from your backup.

Hello all! I would like to ask you guys for some help. I just bought mentioned projector (see subject), and it seems its running some android tv system. I would like to get the latest system possible but i fail to get anything...it seems that projector is no longer supported and i cant find anything literally in the internet. I even wrote to brookstone company but they are not knowing anything either...

Things i was able to find is that current compilation number/build is:

KOT49H.20170626_163421_V1.1.3

I tried to tap multiple times multiple options in the projector to get into developper mode - no effect. Update through system fails as it cant connect to the server (i guess its off due to no further support).

The only thing i managed to find is that its the same projector as ioChow i04 and similar to miroir m220. Unfortunately for these two i also fail to get any info...

Is there anyway to "read" projectors spec through any app, or programme from PC perspective?

I also can disassemble the whole projector to check chip or whatever is on motherboard if this would help anyhow.

In general it works greats connecting with HDMi but i also would like to try make it work as standalone (if possible).

Any suggestions or help you can offer - i would appreciate!! :). Thank you!
[General Accessories] hmattt:
Hey! I just dug up my projector and decided to do some research on it and found your thread through google.

Unfortunately, I do not think you can do anything further than what is on the projector itself. The build of android used is naturally stripped down, and I don't think its possible to "push it" past it's limits (at least on the software side of things ;)). But who knows? Maybe someday we'll see someone smarter than me exploit some vulnerability, for now I can only hope.

Sorry that this reply wasn't very helpful. I just mainly wanted to let you know that you aren't the only one wanting to get the most out of this thing :)
[Device Repair] R7027:
I have a Samsung Galaxy S7 (SM-G930F) that appears to be dead. I found the service manual online and I'm now trying to follow the troubleshooting flowchart for power issues. I am stuck at the third step (already), where it tells me to check the voltage level at a resistor.

So my first question is, how do you check voltage at a resistor in circuit without shortening something out? Ground to either side of the resistor? Multimeter in voltage metering mode?

Second question, what is a "high" voltage? How high is high? High as in digital circuit, like one (high) vs. zero (low)?

Two possible answers are given for this question in the flowchart. One is "No" and the other is "Abnormal". So my third question is, what does "abnormal" voltage look like?
[Device Repair] blackhawk:
Use a good set of probes and don't shake🤣

Clip one to the ground plane so you only need to hold one probe instead of two.

Abnormal is under 2 VDC... I think.

View attachment 5759483
[Device Repair] R7027:
No worries, it all went well. Thanks for the tip about ground plane! I didn't find a plane, but I did manage to land on the ground. ;) (I think got that in-joke right.)

I actually tried using both test leads directly on the resistor and while it did give me a reading, it also started to smell funny after a while. It also read something like 0.44 V. But after putting the negative lead on the metal shield, and positive on either side of the resistor, I got a very different reading. I got something like 3.7 V. Now that I understand the expectation, I know this is normal value. Because it's just the voltage from the battery which is rated 3.85 V nominal voltage. It's a bit discharged but it's OK (Samsung original replacement battery).

I do wish they had put more effort into writing these "service manual" things that they keep so secretive. They got me wondering what they mean by "abnormal" voltage. I admit do being a complete noob when it comes to repairing phones and electronics in general, but they could have used proper English and I would have understood (even though it's not my first language either). Now I understand this "abnormal" to mean "way above 3.8 V or way below 3.8 V". I get the impression they just slapped together some images and text, and they could not even spell things right or draw the little boxes in the flowchart with pixel perfect attention to detail. I do get it though. Why bother when no one else is supposed to even look at this except Samsung authorized service technicians? :rolleyes:

Why below 2 V? How do you figure it's TTL and not RTL or DTL? Full disclosure: I have no understanding of what either of these things mean. I just looked it up on Wikipedia. I do know it has to do with the way electronic circuits are designed, it's engineering jargon. TTL stands for Transistor-Transistor Logic.
[Device Repair] blackhawk:
Pretty sure it's TTL protocol.

You really don't want to muck with most of everything on the mobo. Keep the phone in a good case at all times and keep it away from water. 99% of the time it's easier to replace a defective assembly rather than try to fix it.
[Device Repair] R7027:
Protocol? As in data transmission protocol, like USB? Can you elaborate please? I am only familiar with the term "TTL" in the context of UART interfaces, where you use some kind of USB or RS232 to TTL adapter in order to communicate with defective devices and things of that nature. I have used an adapter like that many years ago to clear a firmware error in a Seagate disk for example so I could recover the data.

I am in a similar situation this time. This phone is not powering on and I need to recover my data. It died suddenly while it was charging. What do you suggest I do to extract the data? I don't care about MOBO or assembly, I just want my data back. But I have no experience with phone repairs, and I have learned that the UFS storage chip is encrypted too. So I can't just pull of the storage chip and put it in a chip reader, do a data dump and then take it from there. I need to repair this board to get to my data. Or is there an alternative?
[Device Repair] blackhawk:
Protocol; voltage specs for different states.

A data recovery specialist may be able to retrieve the data. For you as it it is now, no boot, no data.

Not backing the data up redundantly was a big no-no.

As Dirty Harry said: "A lot of things can happen to an Android...".
[Device Repair] blackhawk:
There are recovery specialists that go as far as pulling the SOC to attempt to recover data. No small or easy task.

Otherwise if you can't get that mobo to run I would write the data off... and save myself a lot of time and trouble for nothing.
[Device Repair] Rizzi87:
I'm stuck in a similar situation with my GT-i9060 (Galaxy Grand Neo) where I could care less about the board or phone and just want my data recovered.

This would be my last-resort attempt to repair but you could try it out maybe. I am attempting to figure out what's wrong with the mobo first and try to get that thing started.

Here's my post. Any inputs would be helpful.
[Device Repair] blackhawk:
Nice find. Last resort time... you see what a pain it is. Very involved and no guarantees.

Is the sim card still intact; are your contacts stored on it?
[Device Repair] Rizzi87:
Thanks for the reply.

The SIM is still intact but no, my contacts aren't saved on it. My Whatsapp backup is on there too and yes, I was ignorant enough to not have backed it up :rolleyes:

As I mentioned, if I try to switch it on using the battery or even plug the charger, certain areas of the mobo get hot which points out to some component being shorted (according to my limited knowledge)

I'm trying to test each component using the schematic diagrams because the repair flowchart mentions some equipment that I don't have access to. Gonna pop open the emi shields today so I can test those components too.

I also have a G930F with a bad display (I think) but that will have to wait ;)
[Device Repair] engage4:
You can't repair a mobile with just a flow chart. You need to be proffessional and also need some basic tools like dc power supply. Mobile pcb's most DC bus lines will normally shows below 30ohms resistance.

Connect phone to pc with charged battery and check phone's SOC detects or not, if detects probably emmc/bootloader failure.
[Device Repair] blackhawk:
You're welcome and welcome to XDA🤗

That link was an interesting read.

If you really need the data just stop now and send it in. If you have already or do damage the memory chipset it will be game over. One price quote I heard was $800 from another member here. Can't recall if they had to hot air the memory chip off or not.

Many people have no idea the trouble not backing up critical data causes or how fragile digital data can be. I have at least a dozen backup drives, many are redundant copies. No such thing as too much.
[Device Repair] Rizzi87:
@blackhawk Yeah, I will probably head over to some recovery specialists and then experiment with getting the board to work again.

@R7027 - If you have the service manual for the G930F, can you check if it lists the main parts and exploded view for the phone?
[Device Repair] Renate:
Forget "TTL" and 5V. There is nothing on your board that is at that level.

Sometimes signals that are designed for external things run at 3.3V, but they usually use a converter.

An actual SD card (if it's from the stone age) uses 3.3V levels.

Normally the system will just say, "Can we just talk at 1.8V levels?" And they do.

Most processors of the last decade work at 1.8V or less.

If a signal comes right out of the processor it will be at that level.

For instance, my Onyx Poke3 has UART running on 1.8V levels.

So, back to your power button. That's internal. It connect directly to a GPIO on the SOC.

That means the voltage levels are probably 0V to 1.8V.

I'd guess that "R7027" is a pull-down resistor to ground.

That means the power switch is connected to 1.8V and it pulls the input on the SoC up.

(Many other things tend to have a switch ground things and they use a pull-up resistor to 1.8V)

Did you find the test point for the power switch? Did you see what happens when you push it?

It should go to 1.8V (obviously).
[Device Repair] blackhawk:
What's the name of that protocol? The low/high threshold ranges for 1.8VDC?
[Device Repair] Renate:
CMOS or LVCMOS

Earlier logic families didn't generally go rail-to-rail, i.e. the full range of the power supply.

Since CMOS (complementary metal oxide semiconductors) the logic swings from the negative power supply (usually zero) to the positive power supply.

Over the years the voltage has gotten lower to reduce the power needed to swing the parasitic capacitances.

Your desktop probably runs at less than 1V

There is 5V on your cell phone motherboard, for the USB power in and the USB power out when powering peripherals.

Even then the actual logic on the data lines only swings from 0 to 3.3V (in USB2 low and full speed).

In USB2 high speed, it's 0.4V
