Help Unbrick Coolpad F1 8297 - General Questions and Answers

I have a Coolpad F1 8297 (from Hong Kong) which is currently bricked. The problem is unique for me. Sometime back I had rooted my phone and installed custom Rom (something like ASOP don't remember exact name and probably it was for 8297w). The same was installed through TWRP recovery module. I am sorry but I must say that I was playing around with TWRP options and through mistake I deleted something and since that day my phone remained in boot-loop. I can only see the Chinese script & F1 displayed on the screen when I push the power button. I also cannot enter TWRP recovery. I tried to connect to the PC but even then it would not connect. I have installed all necessary drivers etc. Tried changing ports, cables and everything that I found on the net. When I attach the device to PC it connects and disconnects and this goes on endlessly. Please therefore help me getting a fix for my phone. Thanks.

Help Please Please with my bricked Alcatel Ot 5020 (Evolve)

This is my first time asking for help directly here, I always find the answers in the other threads solved, but this time I can not find an answer.
I have a alcatel one touch 5020t evolve its a MTK6575 (t-mobile but is used in el salvador), I used to MTKDroidTools to install CWM Revocovery, I did back up with the same program but apparently did not because i look and i cant find anything in the back up folder, only left some files called:
ALCATEL-ONE-TOUCH-5020T_130818__boot_patched_140129-175612.img
ALCATEL-ONE-TOUCH-5020T_130818__recovery_140129-175612.img
in the folder called recovery.
Now the phone on, the startup screen and then turns off, I can enter a menu by pressing on + vol +, where it says enter recovery mode or normal mode, before they tried to install cwm I could go in and delete everything from there, now I get the menu of recovery mode and normal mode but since does not enter recovery mode, got it turns off, like when entering the normal mode.
I tried to flash with sp flash tool but I get an authentication error that is on the img
The pc recognizes my phone, makes the sound when you connect something, now if we go to Device Manager, a device called first appears:
MTK USB Port
After that is disconnected and then a new one appears called :
Media Tek Preloader USB VCOM Port
But there ir a problem, then this becomes a repetitive one disconnects and connects the other, but only when I connect the phone without battery only stays in:
MTK USB Port.

Sorry, but i could not solve yet, nobody helps me
So were you able to flash cwm to the device? there are several threads requesting a custom recovery for this device and either way could you upload those first two .img files I may be able to use them to try to recover my device
*** Okay so the problem is that the boot loader on this device is locked and for the time being a custom recovery is not possible. I still have access to the recovery on my device so if I could find a way to build an update file from the source code or an official firmware update I could fix mine. Yours may be too far gone. sorry.
any luck with a solution? How close to one have you got to...

A friendly warning: Don't just mess around with the Bootloader, that's one delicate piece of software, try to find how to unlock it first, then we can talk of changing the recovery. For rooting purposes I can attest that you can safely root it using the OneClickRoot solutions around the net. I used some chinese root and it worked like a charm.

I have had a OT-5020T with all the same symptoms as you describe. After much research and diagnosis here is what I have learned and know to be true.
You have soft bricked your phone. For this phone it results in the boot loop you described. At present a Custom Recovery that works is not available for this phone and any attempt to flash an existing one results in a soft brick. There are apps that will flash a Custom Recovery while the phone is one but once you reboot ... !!! Bricked!! This is because ...
a) the memory mapping for this phone is different that other OT-5020 models, so the Custom Recovery placement and indexing is wrong when flashed, causing the boot-loop, and inability for Custom Recovery to load,
and ,
b) the bootloader is locked for the 5020T (different story for other OT 5020 models), and no one has found a way around it yet. Trying to flash back stock firmware for the OT-5020T requires it to be unlocked.
One Touch Update 2.8.0 doesn't seem to want to work one the phone has been altered in this way. SPtools won't work because you need an accurate OT-5020T scatter file (memory map) ,and certification file (bootloader unlocker) to flash any image. In addition to all this the phone doesn't maintain a steady usb connection long enough to allow use of android tools adb and fastboot commands although it does can stay connected in a different mode.
What I have used to restore my phones firmware is a package from Furious Gold that allows the phone to be flashed to factory firmware. I have used it successfully, so I can confirm that the phone wasn't a permanent brick.

hi XDA community i have a problem regarding my a850 and i hope u or anybody can reply this comment in an instance cuz im in emergency...
IM EXPLAINING MY PROBLEM VERY DETAILED SO IT'S GONNA BE VERY LONG COMPOSITION, INCLUDING FROM IM ROOTING THE PHONE UNTIL I TYPED THIS COMPOSITION
so recently i "Framarooted" my device and was working properly as i expected,then i want to install TWRP, i see my baseband version does not have ROW or CN in there, it kinda like "A850.V13 ...(cant remember)", but i flashed anyway using the ROW version of TWRP and Mobileuncle MTK Tools. When I want to enter recovery (via MTK Tools) it doesnt show up, just stuck at white,big "Lenovo" logo (it probably doesnt work) but i was able to boot back to normal. Then i used System App Remover from Play and attempted to delete some chinese apps, and I DID a mistake... i was so clumsy enough to delete all chinese apps that origins from the rom i accidently deleted the file "classical" (which i guess the entire system ui, launcher etc) . Upon after deletion of that file I SHOULD HAVE NOT DELETE , it suddenly booted off with the startup sound muted halfway (its like, the boot startup sound have like 4 second duration and i heard the sound just for 1 sec).
Then it boots up again, but stuck at the logo "Lenovo For Those Who Do" after startup animation, so i assume this is bootloop or soft brick
Realising this incident i GOOGLED " a850 bootloop","a850 unbrick","a850 stock rom","a850 emergency reset" and "a850 emergency backup", then I found a website which describes how to flash stock rom to a850, so i did that, as it might work, but actually not for my case. I followed and downloaded exactly steps and files from that website and loaded Flashtool with its scatter file, then ticked PRELOAD and selected the preload.img, followed by checking USB mode ,clicking "Forced High Speed", checked the DA DL thingy, clicked Firmware Upgrade and the progress bar moved, after that i plugged my phone, without battery, to the pc via usb. I heard the hardware insert sound, but, Flashtool did not start flashing, it;'s still SEARCHING.
Then I read that u need the USB drivers, so I assume i do not have drivers for this phone. I used the Device Manager step and when I plug my phone, it pops up "MT65xx Preloader"(or MTK i dont remember) then I quickly rightclick and "Update Driver". It has two selections, ONLINE or BROWSE, so i clicked the online solution, but Windows seems cant find the driver i need,
so i used BROWSE option, which i used your usb driver by entering the directory of the driver in your file in "C:\Users\User\Downloads\Compressed\Lenovo_Drivers_SP_Flash_Tool_v3.1316.0.150\Drivers" clicked install then it pops up an error "The third party INF does not contain digital signature information", so it doesnt install. So I used USBDeview and plugged my phone again without battery, it pops up "MT65xx Preloaded" with a purple dot, and if you need, i rightclicked that purple dot and clicked PROPERTIES, and here's information it gave:
Device Name: MT65xx Preloader
Device Type: CDC Data

Driver Description: *blank

Instance ID: USB\VID_0E8D&PID_2000\5&9ec43f0&0&9
After checked, i resorted to HARD RESET via recovery (i tried to go to recovery again to see there's hope in there) and it BOOTED TO RECOVERY! (yay) but again problem strikes, the recovery I see now is FULLY CHINESE i dont understand even a single option i gave there.
So now my phone condition is still cant boot to launcher, and my very last resort is to use the JTAG option
pls help me u all and pls reply ASAP
thank you

You should log in to windows with out drivers verification in order to install the drivers. Tutorial on how to do than on windows 8 here. Then flashtool should regognize the phone... (you should fix this problem because you may also need it in the future)
There is also a way to fix your phone (if the classic theme is the problem) using ADB. Go to this page and scroll down to ADB method(tutorial) in order to install the classic.apk as a system apk through ADB.
(i am attaching you the apk: View attachment Theme_classic.apk)
Very thanks though cuz this actually solves my problem on my previous devices which doesn't detect upon connection, but I've actually resorted
to do unsoftbrick by a more professional person in my town (he sells and services phones) and it charged me RM50 ($15). Now my phone is back to normal with a rooted state (Chinese superuser app)
Again thanks for replying.
PS:also can somebody redirect me to lenovo a850 modding page? anybody

[Q] How to unbrick Xiaomi Mi3

Hi guys.
I have for a few weeks one Xiaomi Mi3 16GB Snapdragon (WCDMA). Because I thought it was too slow, I flashed another rom by Mirecovery, but I think I used a wrong one because the phone is completely dead! I am not able to get access to the recovery mode or fastboot. The keys don’t work anymore.
This is the rom I flashed: xiaomi.eu_multi_NX403A_4.7.11_jb-4.2. downloaded on miuiandroid.com.[later I heard this is a rom for zte z5s mini, so really wrong one ]
After installing of MiPhone2.11.6, the first time when I connected the phone with the pc, the red led kept lighting on and the driver wasn't installed, but the phone was recognized by MiFlash(com20, i think): flashing did't work because there wasn't a communication with the port. After that I tried to reinstall MiPhone and afther some attempts, when I connected the phone with the pc, the red led kept lighting on for a few seconds and the driver was installed. But the phone wasn't anymore recognized by Miphone, so again no possibility to flash it.
I’m really desperate because i used the phone just for 2 weeks.
I would really appreciate if somebody would come with a good solution.
Thank you.

if you have no access to recovery or fastboot, the phone is finished
one of the worst things you can do to a device is flash the wrong software, as you see.

Partially bricked Mi4c mi-globe 7.2.9

Good day gents and ladies
Well let me start from the beginning.
I'm was using mi-globe 6.12.22
Last week Friday evening downloaded 7.2.9 mi-globe,read around the mi-globe forum.Didn't see anything funny so flashed via twrp on Saturday morning.Hmmmmmmmm this is when all my problems started.
Basically what I should of done is download 7.2.9,new 3.0.3 twrp for norgat,go into recovery flash new recovery, restart recovery,flash 7.2.9 and then have happy days.But it wasn't to be and now I'm basically sitting with a useless mi4c device.
The device works but warms up and I only get about 4 hours battery life.
If I try boot into recovery I just get black screen.
If I connect device to PC it is not recognized, have tried 3 x different laptop/PC's and different cables.
So fastboot,mi-flash,mi-unlock are all not possible as device is not recognized.
I have been trying different solutions without any success.
I think if it would be possible to root device directly without PC then maybe it will be possible to get flashfire working and I can flash new norgat recovery?
Any suggestions would be greatly appreciated?
NB.I have tried loading Qualcomm drivers ,google drivers etc etc.no luck can't connect my device too PC,either get device not recognized or the PC doesn't even see the device.Enable USB debugging etc etc nothing works.Been fiddling for 4 days!!!!!!!
Tried to root with kingoroot,framaroot directly on device etc nothing works?
Please help,else device is a nice piece of plastic that holds paper down on my table.lol

Is usb charging via pc working and have you tried miui updater? , This seems weird state you have ... If none working might be tried deep flash cable flashing ... Or go to nearest service center. Hope that help. Best luck.
Hi,yes USB chargers device via PC but that's all.
How does one deep flash,could you post link please?
I bought the device in China about 18 months ago,Xiaomi never sold mi4c in my country so doubt they could help me locally.
Seems I have soft bricked the device?Tried every thing no solution.
If it would possible to root without USB cable I could maybe try flash new twrp via flash fire?Then could wipe all and try start again?

You havent answered the miui updater part, have you tried flash miui rom.zip, using miui updater apps ?
Does fastboot mode boot on your phone ? i mean the bunny sceen showed up ?
For dfc here the link http://xiaomitips.com/guide/miui-deep-flash-engineering-cable-solution-to-non-edl-device/
Please take dfc as last resort. And do research more on this... Do with your own risk. Good luck
Hi,
Yes sorry I have tried updater, I download rom start updater it starts but after about 2 minutes stops and phones shuts down.
I then have to restart phone with long press of power button. It restarts but nothing has changed.
Wrt fastboot it goes into fastboot but this is useless cause no Pc can see my device and if it sees it it sees unknown device, spent countless hours trying different things without any success.
Seems have soft bricked the device, phone works but gets hot and battery life maybe 4 hours if I'm lucky?
Not sure what more today?

Before this has your pc able to use the miflash ? Try to follow this guide to setup it correctly http://en.miui.com/thread-136188-1-1.html ... I follow this guide and the adb n fastboot even works on an old pentium 4, 512mb ram, win xp laptop.
Ps: I think, its only a matter of incorrect driver setup on your side, best luck.

My galaxy note 3 (SM-N9005) with a custom rom can't see my sim card. How to fix?

This is a bit of a longer story, but i'll try to make it brief.
I have a samsung galaxy note 3 (SM-N9005).
A few days ago, when I was deleting system bloatware and I must have also deleted some important parts of the system.
My homescreen stopped working and i couldn't see my phone when i connected it to my pc which is running win-10 (more on that later).
Unfortunately i didn't keep any backups, yes I was reckless.
Factory resetting with my default recovery mode didn't help at all.
After some time i managed to install twrp (team win project recovery) and flashed ressurection remix 5.8.5 (unofficial version from Lord_Eko) along with Magisk and the correct Gapps.
Everything is working fine except that I cant see my sim card (thus i can't call or text anyone) and I still can't see my phone when connecting it to my pc.
I wanted to try installing some firmware for my sim card or try flashing stock firmware before my custom rom but I can't, since I have to use bootloader/download mode for that.
I tried using Odin (v3.13 and v3.09) while in download mode, but it can't see my phone. Neither can Android debug bridge when using command "adb device" or "fastboot devices" (it just says list of attached devices and nothing).
Connecting my phone normally doesn't work either. My phone isnt even listed in device manager as an unknown device.
I even tried installing samsung usb drivers, but to no avail. My phone only gets charged from my pc.
I tried all sorts of things i don't even remember now, but none of them helped.
I read something about an IMEI being deleted and when i checked my IMEI through an app it was blank, so it seems to have been deleted.
My battery also keeps draining quite a lot, but that's probably because of how old it is.
I don't know anymore info i can give, so please, how do I get my simcard to work?
Thanks for any help and sorry if I posted this in the wrong section. <3
