I was experimenting on an old device (lenovo tab 2 a7 30hc) and hard bricked it.

I've been trying to install the stock rom from SP Flash tool and installed the mtk vcom preloader drivers but the phone still won't get detected.

Someone please help me out here please.
[Android Q&A, Help & Troubleshooting] respectablenoob:
Install vcom and Lenovo drivers.
[Android Q&A, Help & Troubleshooting] torrbunator:
I had similar soft brick problem with MTK tablet. Generally you need to remove battery (or unplug the battery connector) and install (plug) it back. If your battery has soldered wires you need to unsolder Vcc (usually red) wire and solder it back after a while (like a couple minutes after). If your battery is not able to remove/unsolder/unplug your only solution is discharge the battery and it can takes a long time.

[Android Q&A, Help & Troubleshooting] antifragiIe:
nokia 6 with android 9

i have a problem after restarting the device where i assume the SD card has not yet mounted, and this causes the custom sound files (which are stored on the SD card) to be "not found" and replaced with default nokia sounds or no sound at all (it just points to a file that it thinks doesn't exist)

i figure if i can transfer these custom sounds over to the internal memory, i might be able to avoid this problem. however, i've run into a problem with that too. when i connect the device to the computer (corded or bluetooth) i can see the internal storage directory (and the subfolders ringtones/alarms/notifications) but when i place the sound files in these directories, they do not appear within the android menu after hitting "+" to add a custom sound/ringtone. none of the files will load, instead i just see a blank menu with no files in it. (but the files do continue to appear when exploring the directory from the computer)

so how does this work? lets say i wanted to put custom sounds on my android 9 without an sd card. how would i make that happen for this version of android?

thanks
[Huawei P20 Pro Questions & Answers] JP8296:
Did Huawei already kinda give up on the P20 Pro? I know that there's is coming the EMUI 10, but new features? or features that other phones are getting? The Mate 20 has announced some new stuff like moon mode, DC dimming, ultra-low latency Bluetooth (maybe here there is a hardware difference), the Nova 4 is also getting front camera night mode. Also the camera on the P20 Pro still as a lot to improve especially on the video and front camera. I just kinda feel like they already letting go a last year flagship just like that.
[Huawei P20 Pro Questions & Answers] :
Low latency bluetooth might be because of the bluetooth 5 thing. Guess who's switching if they abandon the phone in the same way they did 2 years ago.
[Huawei P20 Pro Questions & Answers] JP8296:
Is a shame that an 800+€ flagship is just kinda 'forgot' already just like that because there are others flagship to push out to consumers, this phone is great and still can be better but yeah f**k consumers.
[Huawei P20 Pro Questions & Answers] sniper20:
We get every update possible up to emui 10. Who is forgotten??
[Huawei P20 Pro Questions & Answers] :
Some of the features that the mate 20 and p30 have are mostly hardware-related. The 30x zoom could had been bought to our phone, same goes for dimming, ar lens and more stuff.
[Huawei P20 Pro Questions & Answers] JP8296:
This.. Also when is Huawei gonna finally solve the video focus jitters or whatever is?
[Huawei P20 Pro Questions & Answers] dlevick:
Hate to be devils advocate here but if they put all there shiney new tricks on last year's phone what would be the point in the p30, it's a business decision.

Sicks but it's how phones are sold, I think given the p20 is nearly 2 now it's doing well with updates.
[Huawei P20 Pro Questions & Answers] :
Business is business until the customers do a massive refund and move on to something else
[Huawei P20 Pro Questions & Answers] forever_lol:
Something that almost never happens in real life.

The successful company must really fail on many fronts to make majority of their customers go. It must be combination of really disappointing product and terrible financial condition of this company. The closest example that comes to my mind is htc drastically losing its market share in 2011. Their models like Sensation or Incredible S had hardware defects and weren't match for Galaxy S II.

However an average user won't abandon Huawei because they don't want to make its really good p20 pro look (softwarewise) like p30 pro. Every vendor does that.
[Huawei P20 Pro Questions & Answers] JP8296:
I don't wanna my P20 Pro to look like the p30 pro or all the shiny new stuff that is hardware related (impossible of course) but it would be cool to have a last year flagship to record a video without is "focus jumping around" every few seconds and stuff like that that ruin the video and can be improved.
[Huawei P20 Pro Questions & Answers] dlads:
Does feel like we're being left behind tbh.

Emui 10 has been mentioned but no time line specifically. Video stabilization has actually got worse on 9.1 Vs 8.1 on 1080p 30fps

Battery had got worse too.
[Huawei P20 Pro Questions & Answers] JP8296:
This... It's a 800€ plus flagship from last year, the mate 20 will get the emui 10 fast, like every other update til now

Battery performance decreases over time. It's normal for this type batteries. I don't see much difference between 8.1 and 9.1.
[Huawei P20 Pro Questions & Answers] dlads:
There is a difference, it's not normal battery degredation, this is a specific drop between bases.
[Huawei P20 Pro Questions & Answers] forever_lol:
It's not like i don't believe you. I've just haven't noticed one yet on my device. My battery time us pretty much the same.
[Huawei P20 Pro Questions & Answers] :

[Huawei P20 Pro Questions & Answers] dlads:
Were you used to getting 9-10 hours SOT consistently on your P20 Pro on 8.1? And you're still getting that on 9.1 ?
[Huawei P20 Pro Questions & Answers] forever_lol:
I was getting 7-9 hours SOT on 8.1 and now I am easiliy getting more than 7.

In order to determine whether it's normal battery degradation (just an example: my old iphone's battery lost 8% of its capacity over a year) or result of update to 9.1 I would have to downgrade to 8.1 and test which I am not really willing to do.
[Huawei P20 Pro Questions & Answers] dlads:
Ok so that's a pretty obvious drop?

I know personally that the phone is less efficient with 9.1, it is what it is.

You just said yourself that you've noticed no drop yet you've just gone from 7-9 to 7 ?
[Huawei P20 Pro Questions & Answers] forever_lol:
Not exactly, I said I got easily more than 7 hours on 9.1 (it's average time but 8 hours SOT is not that unusual here either.) and that I was getting between 7 and 9 hours (at best) on 8.1 (sometimes it was 7 hours,. sometimes 8-9). This difference (30 min on average) is imo insignificant. I do not expect battery performance on 1,5 year old device to be as good as on brand new one. I use my device the way I used before. At the end of the day (normal usage, not the extensive one) I still have over 40% power left. SOT is imho not the best battery indicator to be taken into consideration when comparing firmware versions. Frankly speaking I'd rather compare battery drop on screen off/deep sleep.
[Huawei P20 Pro Questions & Answers] dlads:
I dunno, I've always got the most out of my phones. Admittedly this is the longest I've kept a device for, I usually get 2-3 per year.

I'll never overcharge (overnight) I'll always use non advert driven apps and I'll always streamline my device so it's light, so I'm pretty accustomed to what I use, the locations I use it and the subsequent battery usage and state that follow.

As im borderline OCD with this stuff, a variance in battery life without a significant change can mean only one thing.

The jump to 9.1 for me from AOSIP (which isn't even official lol, 8.1 and 9.0) I saw a heavy drop.

Still within the confines of what's acceptable, but nowhere close to what it would be should I downgrade and stick on AOSIP on 8.1 or stable 9.0

Either way. It's fine. It's impossible to compare two users devices, when there's so much that can differ.

Bare in mind that I've had 17 hours 45 SOT out of the p20 pro on 8.1 when I was sick over a weekend.

I've no chance of getting that now, no chance.

Hi, there

I have a A8+ with cracked screen and bought a display from ebay, however the touch function doesn't work on that new screen. After reading some of the related topics for other Samsung models, I figured that my screen is not original and will not work with the stock rom.

I'm wondering if there's similar kernel with that check disabled I could use to make my A8+ work again? so far I've tried Quantum_Kernel-A8_v4, and [Samsung][ROM][PIE][9.0][06-July-2019][A8_A8Plus_F][v11]LightROM without luck.

Is this all I should have for a DRM intact, bootloader locked device?

I notice that not all entries have [Key OK][Active] next to it.

Does that mean the device has been unlocked before and keys are gone now?

And, why does it say something about Factory Reset?

Also, I don't quite know the meaning of some entries (well, if not all).

What does the numbers mean following:

Although these might not have any significance.

I know all of us have a ton-o-fun reverting the settings back after flashing new ROMS (ok it's not really that fun...). But every time I change ROMS my data connection settings get messed up. Examples are Google Mpas can't connect and emails won't automatically download. I've searched and searched and haven't yet found a deffinitive answer to the isp.cingular / wap.cingular settings.

Presently I think I am just going through a WAP sever which from what I understand isn't all that great or fast. I am paying for unlimited data (w/out teathering), am I able to connect to the isp route? I guess the reason I'm asking is because I don't know if I've ever been able to get a good set of instructions on setting it up.

I know this is kind of a newb question but could someone please post a step-by-step for everyone to have?

Hello all

I have a Verizon galaxy note 9 that I flashed using AT&T pie update. So I'm still stuck on QS1CSAA January 1 update. Haven't been on forums much. I would like to get back to standard Verizon OTA updates.

As of now, while still on QS1CSAA, my phone says it's up to date. Probably because of at&t flash. How do I go about getting back to "normal boring Verizon phone"?

[Samsung Galaxy S7 Questions and Answers] CentennialMan:
So, I'll apologize if this has already been dealt with previously, but I just need to verify what I've been told by a friend who knows Android systems (and Samsung S7 phones) a LOT more than I will ever attempt to understand..

About a year ago, I bought a Samsung Galaxy S7 from a 'rebuilder' (my term) who mentioned at the time "... it was ATT phone..", and, yes, when I turn it on it does the ATT circle jerk logo and has an ATT logo on the back of the phone. This was of no real concern to me, because my service purveyor uses the ATT system (Consumer Cellular), so it's worked well enough. But unfortunately, it also has a boatload of 'semi-proprietary' ATT trash in the phone which I'd like to get rid of. To confuse the matter even more, it appears that I cannot 'unlock' the phone because it has not been associated with an actual active ATT account for close to two years, and it APPEARS that now they refuse to accommodate an unlock code for this phone.

So... according to my friend (Mr. Android Phone), I can 'root' this phone to 'factory original firmware' and make it (in essence) just a plain-old-vanilla Samsung S7 without this rather bogus ATT firmware and the myriad of craplets I'd like to get rid of..

So, I'm here looking for "expertise" in such things because I certainly don't want to 'brick' this pretty nice phone, but I also want to get this to a point where there is no association with ATT in any manner. So my question sorta comes down to: "can I root this and be rid of all things ATT?", and "will this allow me to achieve an 'unlock' without having to play ATT's games? (I had QUITE the discussion with an ATT 'support' dude a couple of hours ago when he flatly refused to give me an unlock code so I could simply ATTEMPT to see if Consumer Cellular's T-Mobile service might work better at my home, since CC tells me I'm right in the center of a brand new rebuilt 4G service area).

Does any of this make any sense to anyone? Pardon my ignorance, but if the IMEI # is somehow 'tethered' to ATT and they won't "release" it, how does rooting help with this? - or is this something more like an 'association' of the IMEI # AND the ATT firmware...? GAH!! I'd just like to be totally rid of all this ATT junk and have the freedom to choose whichever service I want.
[Samsung Galaxy S7 Questions and Answers] cooltt:
Hi There that's a lot of words partner! I'll try make the answer easy to understand and I've cut out much of the post so my reply isn't huge.

1. Yes you can install vanilla firmware which will remove all branding from AT&T and you don't need to root the phone to do this. here is the firmware for your device >>here<< You can also use XAS or XAA. You will see the guide and the Odin you need to flash this firmware.

2. This is another version of Odin on this website if you have any issues with the one on Sammobile. >>here<<

3. Unfortunately you cannot unlock the phone unless the original cell phone provider gives you their half of the unlock key as a code to input to the phone. In the UK once a phone is out of the initial contract period it is illegal for the provider to refuse to give you this code whether your still with them or not. I know in the USA you guys gets ****ed over. The original account holder of the phone can ask for the unlock code but not you.

4. Changing the firmware and unlocking the phone to any network are two different things, flashing unbranded firmware will not unlock the phone the network is tied to. They don't make it that easy!

5. As far as i know T Mobile (USA) has also moved to G930U firmware so you could be lucky with a T Mobile SIM working once the phone is flashed with this firmware but don't hold your breath. Check Sammobile for the T Mobile firmware too.

6. IMEI number is tied to the phone so in theory it can be changed after the phone is rooted and you are able to modify the EFS partition but it is extremely difficult even for veterans like me and it causes lots of problems with cell network registration. Leave well alone if you don't want a completely useless device.

Things to make flashing go easier

1. Turn off FRP lock or sign out of the Google account on the phone or delete it before you do anything, you can put that account back on the phone after flashing.

2. If you enable Developer options make sure " usb debugging" is enabled and OEM unlock, not essential but can help when things go wrong.

3. Anything you want to keep, pics media etc back up or move to SD card, the SD card won't be touched when flashing firmware.

4. Please follow the guides on how to flash correctly.

Any other questions please ask.
[Samsung Galaxy S7 Questions and Answers] Beanvee7:
It should be noted that if it's an ATT phone it's Snapdragon therefore permanently bootloader locked, OEM Unlock won't actually do anything, that setting only works on Exynos.

The only root method for Snapdragon is to use a leaked engineering bootloader to gain system access, and you can only install the leaked bootloader if your phone is already running old firmware. For up to date phones there is no root method.

AT&T's website says Snapdragon

Wikipedia says Snapdragon

https://en.wikipedia.org/wiki/Samsung_Galaxy_S7#Qualcomm_Snapdragon_820_Models

There isn't a single page when googling AT&T S7 Exynos that backs your claim up. The USA also uses completely different network technology than internationally, using the S7 Exynos in the USA is already known to cause issues with LTE, VoWiFi etc. They'd have to do a hardware refresh of the Exynos SoC if they wanted to support it in the USA, which they ain't going to do a for a 3 gen old phone.

[Samsung Galaxy Note 9 Questions & Answers] jcrompton:
Great discussion .... Thanks

I've been down several roads with this including an S9 Exynos and then an S10

I then tried a One Plus 7 Pro and even switched to TMO because I couldn't get WiFi Calling with AT&T.

Currently am experimenting with a Note 9 that I believe was original sim locked to At&T but now unlocked and now with the most recent U1 firmware

Calling features work fine with TMO including WiFi Calling, but I'm looking to try AT&T as well (my reception is much better in my rural areas with att vs TMO).

Do you know if the calling features will work with the U1 firmware and ATT? ( If I get IMEI compatibility issues squared away with att)

Or do I have to flash U firmware?

I'm awaiting a Note 10 that is unlocked. Wondering if I can get ATT calling features to work on it?
[Samsung Galaxy Note 9 Questions & Answers] IT_Architect:
I do not use AT&T. From what I've read, is no advanced features work with U1 on AT&T. With Verizon, VoLTE and Carrier Aggregation works fine, but ViLTE and VoWiFi does not.
[Samsung Galaxy Note 9 Questions & Answers] BladeRunner:
I live in a T-Mobile fringe area that uses B71 exclusively (at least at my house). My experience with U vs U1 is that even though the signal is relatively weak, -118 dBm, the T-mobile branded U firmware holds the LTE signal fine. On the unlocked U1 firmware the signal is a tad weaker, plus it will drop the signal entirely and give me a no network error and/or it will roam on AT&T hspa. So clearly the Tmo software has optimizations for B71 at least over the unlocked U1.

I also have used a Pixel 3XL, an iPhone XR and a Moto G7 power in the same area. They do occasionally roam but I don't experience the loss of signal that I get with the Note 9 and the unlocked firmware.
[Samsung Galaxy Note 9 Questions & Answers] IT_Architect:
This is very valuable information for a guy on the fence like me.

Thanks TONS!!!
[Samsung Galaxy Note 9 Questions & Answers] bober10113:
on U1 firmware, when you go to the phones dialer and dial:

*#2263#

do you get a hidden service mode menu like attached picture? if so then just force band 71 so that it dosen't switch. you can also disable other bands and leave only the ones you know work best so that device dosent try to switch to other weaker ones that you know will drop. also by setting to forcefully stay on LTE by selecting menu 4 in band selection and specifying the bands it should stop from reverting to hspa. but also might cause no signal. but again by selecting only the bands you know work i believe it should help. i have done many tests and what i do is to force bands one by one and check strength in a place where i know signal is poor. this way you weed out the bad bands. write it down somewhere and then go reactiavte all of them. then go to the disable band menu and remove everything except the ones listed previously and be left with only the stronger ones and stop fone from attempting to connect to random weaker ones.
